Topic: “Electrochemical Deposition and Synthesis of Advanced Nanomaterials for

Electrochemical Biosensors and Energy Storage Applications”

Shen-Ming Chen


Abstract- The existing carbon materials can be classified into activated carbon (0-dimensional), carbon

nanotubes (CNT) (1-dimensional), graphene (2-dimensional) and carbon foams (3-dimensional). Among

these, graphene is well known to be the top candidate; However, preparation of graphene from graphite is

an intricate procedure that can lead to an explosion during the oxidation of graphite. Similarly, the

preparation of CNT also has some practical difficulties due to the complicated instrument setup.

Fascinatingly, the preparation of ACs is simple, environmentally friendly and cost-effective. For the first

time, Pongam seed shells-derived activated carbon and cobalt oxide (~2-6 nm) nanocomposite

(PSAC/Co3O4) is prepared for the high performance non-enzymatic glucose sensor and supercapacitors.

Remarkably, the fabricated glucose sensor is found to be exhibit an ultra-high sensitivity with a lower

detection limit, and long-term durability. Moreover, the PSAC/Co3O4 electrode possess an appreciable

specific capacitance and long-term cycle stability. The high surface area carbon porous materials (CPMs)

synthesized by the direct template method via self-assembly of polymerized phloroglucinol-formaldehyde

resol around a triblock copolymer template were used as supports for nickel nanoparticles (Ni NPs).

Further electrochemical measurements by cyclic voltammetry (CV) and differential pulse voltammetry

(DPV) also revealed that the Ni/CPM modified electrodes showed excellent sensitivity (59.6 µA µM-1

cm-2

)

and relatively low detection limit (2.1 nM) toward the detection of Hg(II) ion. The system is also been

successfully applied for detection of mercuric ion in real sea fish samples. Furthermore, a facile method has

been developed for fabricating selective and sensitive electrochemical sensor for the detection of toxic

-derived

porous activated carbons (PACs). The Pd/PAC-modified GCEs were exploited as electrochemical sensors

for the detection of toxic heavy metal ions, viz. Cd2+

, Pb2+

, Cu2+

, and Hg2+

, which showed superior

performances for both individual as well as simultaneous detections. For simultaneous detection of Cd2+

,

Pb2+

, Cu2+

, and Hg2+

‒1 cm

‒2, and detection limit of 41, 50,

66 and 54 nM, respectively, were observed. Moreover, the Pd/PAC-modified GCEs is also show

perspective applications in detection of metal ions in real sample, as illustrated in this study for a milk

sample. In addition, the synthesis of highly dispersed and stable ruthenium nanoparticles (RuNPs; ca. 2–3

nm) on porous activated carbons derived from Moringa Oleifera fruit shells (MOC) is reported. The

as-prepared MOC carbonized at 900 oC was found to possess a high specific surface area (2522 m2 g

−1)

and co-existing micro- and mesoporosities. Upon incorporating RuNPs, the Ru/MOC nanocomposites

loaded with modest amount of metallic Ru (1.0‒1.5 wt%) exhibit remarkable electrochemical and

capacitive properties, achiving a maximum capacitance of 291 F g‒1

at a current density of 1 A g‒1

in 1.0 M

H2SO4 electrolyte. These highly stable and durable biomass carbons modified electrodes, which can be

facily fabricated by the eco-friendly and cost-effective route, should have great potentials for practical

applications in energy storage, biosensing, and catalysis.

Topic: “Latex Technology and Interfacial Phenomena Behind the Dipping of Quality Medical

Gloves”

Ho Chee Cheong


Abstract- Medical glove is a medical device for the protection of healthcare workers and for

controlling infection. After the emergence of AIDS/HIV pandemic in the late 1980s, the

wearing of medical gloves by healthcare workers have been made mandatory in advanced

countries to curb the transmission of highly infectious diseases and viruses. In recent years

with the outbreaks of avian flu and other highly contagious diseases such as Middle East

respiratory syndrome (MERS), medical gloves have played an even greater role in preventing

the spread of pathogens.

Medical gloves are made from latexes, mostly from natural rubber latex obtained from the

Hevea brasiliensis trees. In recent years they have also been made from a limited number of

synthetic latexes such as acrylonitrile butadiene rubber (NBR) latex, polychloroprene latex

and synthetic cis-polyisoprene latex. One of the paramount pre-requisites for medical gloves

as a barrier device is that it should be impervious to pathogens. Others are it should be

highly stretchable and yet elastic so that it returns its original shape immediately without any

deformation after the force is removed; it is soft and conform to the shape of the hand to

confer comfort to the users; it should be easily donnable on the inner surface of the glove and

able to provide the right degree of grip on the outer working surface. In other words, it should

feel like a second skin to the user to exercise the right dexterity to perform the task.

The choice of the right latex feedstock for the gloves pre-determines its qualities. The

molecular structure of the polymer material of the latex underpins the latex film formation

properties and the physical characteristics of the gloves produced. The ease of processing is

very much dependent on the ability to control the colloid stability of the compounded latex

during dipping. The formation on the mould surface of a wet latex gel and converting that

eventually into pieces of gloves on a very fast moving dipping chain carrying hundreds of

moulds is an engineering feat and requires an in depth understanding of the surface science

involving interactions between multitudes of interfaces on the rapid moving chain. The

ensuing surface treatment of the gloves to impart to them the necessary application

functionalities is another interfacial phenomenon.

This presentation will attempt to elucidate and connect the relevant technologies involving

latex and interfacial phenomena that enable a consistent trouble-free dipping process to

produce quality latex products.

Topic: “Applications of Model Predictive Control for Chemical Processes”

Paisan Kittisupakorn


Abstract- Model based predictive control schemes have been developed for chemical

processes: CSTR, batch reactive distillation and steel pickling process. In this work. State and

parameter estimation techniques have been incorporated to provide estimates of

unknown/uncertain parameters as well as states. In addition, process models used in the

formulation of the model predictive control approach are developed based on not only first

principles method but black box model using neural networks as well. It can be observed that

the applications of proposed model predictive control approaches are applicable in several

chemical processes. The performance of the controllers are much superior than conventional

PID in several cases in simulation such as for set point tracking, disturbance, model mismatch

and presence of noise.

Topic: “Protein Engineering Using Photo-Induced Chemical Labeling Technology”

Hiroyuki Nakamura

Laboratory for Chemistry and Life Science, Institute of Innovative Research, Tokyo Institute

of Technology, Japan

Abstract- Techniques for the visualization of target proteins by small-molecule probes in

living systems are highly important to investigate the function, dynamics, localization, and

crosstalk of individual proteins. Especially, photo-induced chemical labeling is one of the

most very useful strategy for detecting target proteins of biologically active molecules having

undefined action mechanisms. In this paper, our recent developments of target protein

identification and modification using photo-induced chemical labeling technology will be

presented. We succeeded in the design and synthesis of multifunctional chemical probes of the

hypoxia-inducible factor (HIF)-1 inhibitor, that contain a benzophenone as a photoaffinity

labeling group to identify the target protein. HSP60 was identified as a primary target protein,

indicating that HSP60 has an important role for HIF-1α stabilization under hypoxia.

We also focused on Ru(bpy)3 complexes which would genetrate tyrosyl radicals under

light-irradiated conditions. We established a target protein-selective modification thechnology

using ligand-directed Ru(bpy)3 photocatalysts (LDRP). We developed a suitable tyrosyl

radical trapping agent (TRT) which made covalent bond with tyrosine residue under the

reaction condition with LDRP and visible light irradiation. We demonstrated carbonic

anhydrase (CA)-selective modification in mouse erythrocyte lysate Furthermore, LDRP

induced chromophore-assisted light inactivation (CALI) of target proteins under visible light

irradiation in cells. In addition, selective purification and chemical labeling of a target protein

in a protein mixture were simultaneously achieved on the surface of affinity beads

functionalized with ligands. Our technologies are expected to open doors to new applications

of affinity chromatography as well as highly sensitive detection of target proteins.

Topic: “Legislating Construction and Building Materials for Productivity Improvement in

Singapore”

Low Sui Pheng

Department of Building, National University of Singapore, Singapore

Abstract- The presentation highlights Singapore’s journey towards higher productivity and

quality in the construction industry. A significant development in this journey is the

introduction of the Building Control (Buildability and Productivity) Regulations 2011 that

provides the regulatory framework within which design consultants and contractors must

achieve minimum Buildability Scores and Constructability Scores at the upstream and

downstream phases respectively before their projects are approved by the authorities. The

Regulations have also been revised regularly to consider new game-changing technologies

(including Amendment No. 2 in 2017). Through the Code of Practice on Buildability (2017),

this presentation highlights the construction technology and building materials mandated to

meet these regulatory requirements. Singapore is the only country in the world to regulate the

use of specific construction technology and building materials to enhance productivity. This

Topic: “Mechanical Properties and Long-Term Deformation of Concrete Depending on the

Moisture Distribution”

Jin-Keun Kim


Abstract- Moisture inside the concrete structures is hard to predict properly because it is

affected by many factors such as mixture and environmental conditions. However, moisture is

one of the most important factors that affect the mechanical properties and long-term

deformation of concrete which are the fundamental properties of concrete for design and

maintenance of concrete structures. This paper explains the overall concept regarding the

moisture distribution and the relationship between the moisture and properties of concrete.

Also, the improved prediction methods for mechanical properties and long-term deformation

considering the moisture are provided. These prediction methods can be extended to various

concrete structures.

In-Situ Measurements of Carbon Stable Isotopes Ratio in Karstic Cavesby Ftir Spectroscopy

Ira Litvak, Yaakov Anker and Haim Cohen

Ariel University, Israel

Abstract—Carbon stable isotope ratios measurement serves as an important implement for

environmental geochemical processes study. While Mass spectrometry is commonly used for

the task, FTIR (Fourier Transform Infra-Red) spectroscopy has the potential for determining

these isotopic ratios with the advantage of simple in-situ measurements. On-line analysis

enables continuous processes monitoring and decreases sampling errors, caused by the

sampling and the laboratory analysis procedures (e.g. for measurement in the mass

spectrometer).

Variance in carbon stable isotope ratios are results of water-rock interactions, phase transitions,

changes in ambient temperature and humidity, biochemical reactions and more. In this study

carbon isotope ratios were measured using FTIR spectrophotometer in both field and in

laboratory conditions and corroboration of the analysis validity was done by Mass

spectrometer measurements.

The research results suggest that: Carbon isotope ratio (13C/12C) may be determined by

FTIR spectroscopy of the CO2 released from water samples under acidic conditions.

As a case-study, FTIR analysis was used for characterizing phase transitions and water-rock

interactions of runoff infiltrating a cave. By profiling the stable isotope systems, we have

found that the δ13C values, which were calculated using FTIR showed sufficient agreement to

those of the Mass Spectrometer measurements.

A case study analyzing water samples from karstic cave (Sif cave, Israel), verified that: (a) On

line determination of water 13C/12C ratio can be carried out with the portable FTIR

spectrometer, hence can be taken to field measurements as preformed in the Sif cave. (b) The

C concentration sensitivity achieved was 7‰ in δ values, which is applicable for most carbon

stable isotopes applications.

Atom-Transfer Radical Polymerization on the Living Cell Surfaces

Sung Ho Yang

Korea National University of Education, Republic of Korea

Abstract—Simple but highly versatile in the formation of polymer brushes on solid substrates

is surface-initiated, atom-transfer radical polymerization (SI-ATRP), where polymers are

grown, by controlled radical reactions, from the ATRP initiators that are introduced onto a

substrate.1 Although hybrid structures of living cells and synthetic polymers have a great deal

of potential in cell-based applications, such as cell-based sensors, biomotors, biocatalysis,

theranostics, cell therapy, and cells-on-a-chip, it is extremely challenging to perform SI-ATRP

(and of course other polymerization protocols) on the surfaces of individual living cells,

because the reaction conditions are lethal to chemically labile cells.2 In this work, a

cytocompatible method of surface-initiated, activator regenerated by electron transfer, atom

transfer radical polymerization (SI-ARGETATRP) is developed for engineering cell surfaces

with synthetic polymers.3 Dopamine-based ATRP initiators are used for both introducing the

ATRP initiator onto chemically complex cell surfaces uniformly (by the material-independent

coating property of polydopamine) and protecting the cells from radical attack during

polymerization (by the radical-scavenging property of polydopamine). Synthetic polymers are

grafted onto the surface of individual yeast cells without significant loss of cell viability, and

the uniform and dense grafting is confirmed by various characterization methods including

agglutination assay and cell-division studies. This work will provide a strategic approach to

the generation of living cell–polymer hybrid structures and open the door to their application

in multitude of areas, such as sensor technology, catalysis, theranostics, and cell therapy.

Asymmetric Michael Addition of 2-Oxochroman-3-Carboxylate Esters to

Trans--Nitroolefins for Construction of 3,4-Dihydrocoumarin Derivatives

Hui Jin, Soo Min Cho, Geum-Sook Hwang and Do Hyun Ryu

Sungkyunkwan University, Republic of Korea

Abstract—The enantioselective construction of an all-carbon quaternary stereogenic center is

a great synthetic challenge. In the last decade, substantial efforts have been made in the

catalytic asymmetric construction of quaternary carbon centers. Among them, the

organocatalytic asymmetric conjugate addition of prochiral trisubstituted nucleophiles to

b-substituted Michael acceptors has proven to be a powerful strategy for the asymmetric

construction of highly functionalized adjacent quaternary and tertiary stereocenters.

In this presentation, highly enantioselective Michael addition of 2-oxochroman-3-carboxylate

esters to trans--nitroolefins will be described. L-Proline derived bifunctional thiourea

catalyzed reaction can give direct access to dihydrocoumarin derivatives bearing adjacent

quaternary and tertiary stereocenters with up to >99% yield, >20:1 dr, and >99% ee. This

reaction is not sensitive to air or water, and can be carried out facilely on a gram scale without

reducing stereoselectivity or yield. The adduct was further transformed to a

spiro-dihydrocoumarin compound in three steps with good yield.

Biocompatibility-Related Chemical Modifications of Poly (Propylene Imine) Dendrimers

Influence Their Interactions with Coomassie Brilliant Blue Dye

Lukasz Pulaski, Izabela Jatczak-Pawlik, Anna Janaszewska, Dietmar Appelhans and Barbara

Klajnert-Maculewicz

University of Lodz, Poland

Abstract—We have previously characterised a family of sugar-modified dendrimers

(glycodendrimers) with a poly(propylene imine) core for biological applications. Since amino

group-covered PPI dendrimers are strongly cytotoxic, the modifications were designed to

increase biocompatibility with cellular systems. While performing immunochemical studies

on glycodendrimer biocompatibility, we encountered unexpected chemical behaviour of the

nanoparticles with regard to their propensity for binding triphenylmethane dyes from the

Coomassie Brilliant Blue group. These dyes are known to bind positively charged polymers,

including linear poly(ethylene imine) and some dendrimers, but their interactions with PPI

dendrimers have not been characterised yet. We compared dendrimers with various levels and

densities of surface modifications, including several simple and compound sugars as well as

polyethylene glycol, separately or in combination. We present data that demonstrate multiple

modes of Coomassie dye binding to glycodendrimers, including electrostatic interactions with

ionised amino groups, hydrophobic stacking and intercalation. These noncovalent interactions

are significant both for increased knowledge on physicochemical properties of

surface-modified nanoparticles and for practical application since stained dendrimers are easy

to detect using absorptiometry or infra-red fluorimetry.

Synthesis and Characterization of Chemically Functionalized Amorphous Silica Nanoparticles

Equipped with Uniform Nanopores for Removing Heavy Metal Ions from Wastewater

Eun-Hye Jang and Sungwook Chung

Pusan National University, South Korea

Abstract—Silica is a mineral commonly found in nature and has been widely employed in

industrial fields. In particular, amorphous silica nanoparticles (ASNs) are one of the most

common nanomaterials being used in many applications including industrial manufacturing,

composite materials, cosmetics, and foodstuffs due to their favorable physicochemical

properties. Because of their good biocompatibility, facile synthesis, and relatively easy

surface modification and labeling, ASNs are being developed for various biomedical and

pharmaceutical application such as drug delivery and therapy, multifunctional bioimaging

probes, biosensors, etc.

We are developing synthetic methods to prepare chemically functionalized ASNs in order to

use them to remove heavy metal ions from wastewater. We demonstrate highly monodisperse

(< 10%) ASNs with the average size range of ~15−300 nm are obtained from our method.

Furthermore, our methods allow ASNs can be produced with uniform nanopores of a high

specific surface area formed inside the nanoparticles. As-prepared ASNs and nanoporous

ASNs have been characterized by various means of materials characterization techniques

including transmission electron microscopy (TEM), scanning electron microscopy (SEM),

powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray

photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). These results

on the formation and chemical functionalization of ASNs and nanoporous ASNs, as well as

use as a means for removing heavy ions from aqueous solutions will be discussed in the

presentation.

Effect of CoFe2O4 Content on Structural, Thermal, Magnetic, Electrical and Adsorption

Properties of CoFe2O4/Mwcnts Nano-Composites

Mohamed Gaba, N.H. Al-Zahrani, Y.M. A Angari and M.A. Abdel-Fadeel

King Abdulaziz University, Saudi Arabia

Abstract—CoFe2O4/MWCNTs magnetic nano-composites were synthesized via gelatin

auto-combustion method. The weight percent of the ferrite content was found to affect the

structural, thermal, electrical and magnetic properties of the entire composites. XRD

confirmed the presence of the two components. The nano-composites with ferrite ratio up to

30 % only exhibited the characteristic diffraction peaks of MWCNTs while in the higher

ratios the characteristic ferrites` diffraction peaks predominate. FT-IR spectra indicated the

presence of the two components with the existence of some interactions between them. TEM

images showed that MWCNTs decoration was accompanied by a gradual change in the size

of the ferrite particles with increasing ratio. An appropriate decoration mechanism was

suggested based on XRD and TEM measurements. The severe reduction in thermal stability

by addition of CoFe2O4 was attributed to its catalytic activity. VSM measurements indicated

ferromagnetic characteristics and showed a gradual increase in magnetization with increasing

ferrite ratio. Ac-conductivity measurements exhibited metallic properties for all investigated

nano-composites. The obvious decrease in the conductivity at higher temperatures, for ferrite

contents starting from 50 %, was attributed to the degrading of the MWCNTs skeleton and

decreasing electrons delocalization. Depending on the magnetic sensitivity and high surface

area the nano-composites (10 and 20 %) were investigated for the efficient removal of acid

red dye (AR) from wastewater. The effect of various parameters kinetics and thermodynamic

of the adsorption process was investigated and discussed.

Determination of Antioxidant Capacity and Total Polyphenol Content of the Extracts from

Three Different Parts of Olive Plant and the Green Production of Iron Nano Particles (GInPs)

Ulker Bakir Ogutveren, Fadime Karaer, Esra Findik and Burcu Kagnicioglu

Anadolu University, Eskisehir, Turkey

Abstract—In this study, three different extracts were obtained from the stems, leaves and

seeds of the olive plant by ultrasonic method, and the antioxidant capacities and total

polyphenol contents of these extracts were determined. Chemical and physical properties of

GInPs produced using these extracts were identified.

In order to synthesize GInPs, 5 g sample was extracted in 100 mL water at 80 °C during 15

minutes in ultrasonic reactor with 45 kHz frequency. Folin-Ciocalteu method was used for

determining anti-oxidant capacity of the extracts and total polyphenol contents were

determined by FT-IR (SHIMADZU IRTracer-100 Model) and ATR (Pike Tech). 0.1 M

FeCI3 solution as a source of iron was mixed with these extracts using different volumetric

ratio to achieve nano-sized iron particle. The size distribution and zeta potential of iron

particles produced from each extracts were determined with zetasizer (Malvern 500210). The

volumetric ratio of iron solution and these extracts were investigated; these results were

correlated with anti-oxidant capacity and total polyphenol content. Final GInPs products

image was taken by stereomicroscope (Zeiss Discovery 20).

As a result of this study, it was shown that GInPs ranged from 10 nm to 100 nm were

produced easily, and the production efficiency was related anti-oxidant capacity and total

polyphenol content.

Removal of Lead from Water by Electrocoagulation Applying Response Surface Method

(RSM) in an Uniquely Designed Rector

Ulker Bakir Ogutveren, Umran Tezcan Un and Nihal Erginel

Anadolu University, Eskisehir, Turkey

Abstract—Lead is highly harmful to living organisms even in very low concentration. Lead

exposure in humans can have severe neurological and physiological repercussions. The

objective of this study is treatment of lead from water by electrocoagulation using iron

electrodes applying RSM in an uniquely designed reactor. The evaluation of the main and

interaction effects of process variables such as current density, initial lead concentration, pH

and Na2SO4 concentration as a supporting electrolyte on the removal efficiency of lead were

analyzed applying RSM. The levels of the factors were determined with variance analysis

and found to be 10-50 mAcm-2 with the increments of 10 units for current density, 50-250

mgL-1 with the increments of 50 units for initial lead concentration, 3-7 with the increments

of 1 units for pH and 0.01-0.09 molL-1 with the increments of 0.02 units for Na2SO4

concentration.

As a result of study, it was found that current density has a linear effect while current density

and initial pH have quadratic effects on the removal efficiency. Lead removal efficiency

reach a maximum value of 98.76% when the current density was 40 mA/cm2 and initial pH

was 4.7.

Mechanisms of Asymmetric Periodic Patterns in Precipitation of Calcium Phosphatein

Hydrogels

Min Kyung Jo and Sung Ho Yang

Korea National University of Education, Republic of Korea

Abstract—Biominerals such as bones and teeth are constructed of natural organic-inorganic

hybrids under elaborate controls in living organisms and mimicking these of perfection

structures, which is called biomineralization, has attracted many researchers’ attention.

Biomineralization is important in that it can be not only used for bone regeneration but also

for bottom-up microstructure designs. Bones are a complex system comprised of both organic

and inorganic components that are mainly collagen fibrils and calcium phosphates

respectively. Hydrogels are suitable matrices for biomineralization because they are very

similar to natural tissues and extracellular matrices, the organic components of bone, and can

be used for controlled diffusion of growth factors. We performed calcium phosphate

mineralization in a gelatin gel and unique structured periodic patterns which are a kind of

Liesegang pattern are discovered. Liesegang pattern is a discontinuous and periodic

precipitation bands under condition that the electrolytes diffuse into the gel containing other

electrolytes. The patterns are differentiated from ordinary Liesegang patterns by asymmetries

in each single band. Although there are abundant asymmetric structures in nature, few

asymmetric structures are investigated. The mechanism behind peculiar asymmetric periodic

patterns are investigated on the basis on the interaction between reaction and diffusion, which

is an insignificant factor in ordinary Liesegang pattern systems.

Finding the Simple Rule for Diagnosing the Operation Fault of Freezer

Seung Yeoun Choi, Bok Han Kim and Sean Hay Kim

Seoul National University of Science and Technology, South Korea

Abstract—This study aims to find a simple rule if freezer is left open, or refrigerant is

insufficiently charged. We have a comparative experiment to find an opportunity that the

simple rule is able to replace the machine learning approach. In contrast to the previous study

performed with the machine learning approach, this paper has derived more explanatory

variables and rules for diagnosing the operation faults of freezer. i) Freezer wall temperature

is found to be the most sensitive variable for diagnosing the door opening. When the open

door rule based on the freezer wall temperature is applied to the actual state, however, only

62.4% of windows are assessed as “True”. In other words, there is 37.6% chance of false

alarm. ii) We also assume that refrigerant mass is proportional to the ratio of accumulated

power to power factor. However, only 51.5% of windows turn out “True” when the

insufficient refrigerant rule is applied to the actual state. When refrigerant is actually

insufficient, 33% chance of critical false alarms still occur, which can harm the credibility of

the insufficient refrigerant rule. iii) To diagnose if the door leaves open by means of using

machine learning, all three variables (Active Power, Laboratory indoor temperature,

Refrigerator wall temperature) may not be necessary. Only the refrigerator wall temperature

but framed with 3 min window appears sufficiently credible, rather than the refrigerator wall

temperature at each time step. iv) To diagnose if refrigerant is insufficiently charged, instead

of the three variables, only power related variables including active power and power factor

would be sufficient for simpler monitoring and more accurate assessment.

Full-Scale Standard Fire Experiment and Numerical Modelling Behaviour of Non-Load

Bearing Calcium Silicate Partition Drywall

Ching-Yuan Lin, Yinuo Wang and Ying-Ji Chuang

National Taiwan University of Science and Technology, Taiwan

Abstract—The study uses the non-load bearing calcium silicate partition drywall as the test

specimen, with full-scale standard fire test and the CFD finite element numerical modelling

simulation on 300 cm × 300 cm area specimen. The whole process of experiment fire test and

the numerical modelling simulation result is highly correlated. This numerical modelling

simulation can be applied to other researches on the other wall systems. This is an innovative

and valuable research. Since they are highly correlated, the CFD finite element numerical

modelling can be processed to work out the predicted results before the test, which can

greatly save the cost of test. When the predicted results is satisfying, the standard fire test can

be processed to verify the results.

Synergy Action of Glass Powder and Foaming Additive in Production of Lightweight

Cement-Based Materials

Jaroslav Pokorný, Milena Pavlikova, Martina Záleská, Jiří Studnička and Zbyšek Pavlí

Czech Technical University in Prague, Czech Republic

Abstract—Waste glass in the form of finely grounded powder can be, due to its assumed

pozzolanic behaviour, used in cement and concrete industry as a Supplementary Cementing

Material (SCM) helping to reduce the consumption of natural resources and emission of

greenhouse gases. In this sense, the presented paper is focused on the use of waste

borosilicate glass in production of cement-based lightweight composites. For both Portland

cement and glass admixture, chemical composition, pozzolanic activity and basic physical

characteristics were accessed. In composite mixes, cement binder was partially replaced with

glass powder in the amount of 15 and 20 mass %. In order to produce lightweight materials,

foaming agent in the amount of 0.58 ml/kg of blended binder was used. For the developed

materials, bulk density, matrix density, total open porosity, mechanical resistance, water

transport parameters and thermal properties were tested The obtained experimental results

revealed pozzolanic activity of micro scale milled waste glass that led to the decrease in

porosity and thus improved mechanical resistance of the investigated composites. High

porosity of foamed concretes significantly improves their thermal-insulation function and

helps to save raw materials for their production.

The Effects of Carbon Fiber Reinforced Polymer Strengthening on Cylindrical Steel Storage

Tanks under Bending Shear Load

Phan Viet Nhut and Yukihiro Matsumoto

Toyohashi University of Technology, Japan

Abstract—Large thin-walled cylindrical steel storage tanks play important roles in the

development of economy and infrastructures. Storage tanks subjected to internal pressure can

cause buckling modes, especially elephant foot bulge at the bottom of the tanks. The design

of tanks against buckling is very necessary. In this paper, the load-carrying capacity and the

failure modes of the storage tanks subjected to internal pressure under bending shear load

will be calculated by the finite element analysis. The results will be compared with the design

method from Architectural Institute of Japan. Moreover, this paper will also consider the

effects of the use of carbon fiber reinforced polymer layers to strengthen storage tanks

against buckling and the increase of the load-carrying capacity of the tanks under bending

shear load.

Cyclic Loading Tests of Composite Moment Frames Using Octagonal CFTs

Jong Jin Lim and Tae Sung Eom

Dankook University, South Korea

Abstract—This research investigates the seismic performance of two interior beam-to-column

connections with floor slabs. Concrete-filled octagonal steel tube column, H-section steel

beam, and U-section steel beam were used for composite moment frames, respectively. To

release the stress concentration at the column face, two design methods were proposed. First,

H-section steel beam passed through the column, directly. Stopper plates were also used at

the column faces to decrease the slip deformation. Second, top and bottom flanges of

U-section beam were not welded to the column face. Instead, to transfer the tensile force of

the beam flange, reinforcement bars passing through the column were welded to the beam

flanges. The test results showed that the ductility of moment connections was sufficient in the

case of through details; However, the load-carrying capacity was significantly affected by the

details of beam-to-column connections.

Study on Mechanical Behavior of Self-Tapping Screws Connection Using Washers in

Single-Lapped Glass Fiber Reinforced Plastic Plates by Experiment and Finite Element

Analysis

Nguyen Ngoc Duong, Phan Viet Nhut, Chito Satake and Yukihiro Matsumoto

Toyohashi University of Technology, Japan

Abstract—In recent years, mechanical characteristics of Glass Fiber Reinforced Plastic

(GFRP) connections using bolts/rivet have been researched in detail, and they are used in

many GFRP structures. However, the connection lack bearing strength compared with

material strength and they need the prepared holes. In this paper, we surveyed the

self-tapping screws connection strength and effects of washers on connection strength of

single-lapped GFRP plates using self-tapping screws under tensile-shear loading by

experiment and finite element analysis (FEA). The strength of self-tapping screws connection

in GFRP plates depends on the washer's diameters. When increasing washer's diameter, the

bearing strength of connections increased. Hence, increasing washer's diameter at reasonable

levels is an effective method to increase the load carrying capability for self-tapping screws

connection in GFRP plates. Moreover, FEA was proposed to investigate the bearing strength

of connections and there were good agreements between FEA and experimental results.

Properties of Portland Cement Type V Mortar Mixed with Ground Rice Husk Ash and

Limestone Powder

Burachat Chatveera and Permphon Srinourn

Thammasat University, Thailand

Abstract—The objective of this research is to study the Properties of Portland cement Type V

mortar mixed with Ground Rice Husk Ash (GRHA) and two types of limestone powder (LS1

and LS2). The physical and chemical properties of Portland cement Type V, ground rice husk

ash, and limestone powder were tested. The properties of mortar such as water requirement,

compressive strength, compressive strength loss and drying shrinkage were investigated. The

solutions used in this study were sodium sulfate (Na2SO4) and magnesium sulfate (MgSO4).

The concentrations of both solutions were 5% by weight in accordance with the ASTM C

1012 standard. GRHA, LS1, and LS2 have particle sizes of 29, 12 and 128 µm. The

replacement levels of GRHA, LS1, and LS2 in Portland cement Type V were 0%, 20% and

40% wt. of cementitious materials. The ratio of water to cementitious material was controlled

based on the water requirements conforming to flow value at 110 ± 5%. The results showed

that the compressive strength of mortar was decreased with increase the percentage

replacements of GRHA and LS in Portland cement Type V. At 180 days, the compressive

strength of all mortars was lower than that of the control mortar. Mortar containing 20% of

GRHA and LS (C80R10LS110) was the highest development in compressive strength and as

high as that of the control mortar. From the results of sulfate resistance, it was found that the

higher was the percentage replacements of GRHA and LS in Portland cement Type V, the

lower was the strength loss and drying shrinkage of mortar. The strength loss of mortars in

magnesium sulfate solution was more than those in sodium sulfate solution.

Abstract—The reinforcement design and seismic performance analysis of the Teaching

Building of Jiangyan Experimental Elementary School are investigated in this paper. Firstly,

according to the seismic assessment results from an inspection company, the seismic

strengthening design is conducted by using the methods of enlarging sections and sticking

CFRP. Secondly, a three-dimensional model is established by using the structural analysis

software Open Sees, and both the dynamic characteristics and seismic responses under

frequent earthquake of the structure are analyzed. Lastly, the dynamic elastic-plastic time

history analysis of the structure is conducted under rare earthquakes, then seismic

performance of the structure with and without strengthening are compared under far-field

earthquakes. The results show that the seismic performance of the structure is effectively

improved, as the maximum reduction of the storey drifts can reach 35%, when the structure is

Experimental Investigation on Inelastic Cyclic Behavior of Bracing Member with

Wide-Flange Section

Dong-Hyeon Shin and Hyung-Joon Kim

University of Seoul, South Korea

Abstract—Braced frames have been frequently employed as the lateral force resisting system

of low- to mid-rise buildings. However, available test results are relatively limited to

establish analysis models of braces with wide-flange that are required to capture their

inelastic cyclic response. To address this, a full scale quasi-static test of a brace with

wide-flange section was carried out to investigate the important structural characteristics

which significantly influence its inelastic cyclic behaviour. This paper focuses on the

buckling strength, tensile yield strength and local buckling of the test specimen and compares

them with those predicted using an existing physical theory model. The physical model well

predicts the hysteretic curve within tensile regions. However, the analytical compressive

resistance of the specimen after buckling is overestimated compared to that obtained from the

test results.

Can Existing Design Codes Be Used to Design Flexural Reinforced Concrete Elements

Strengthened with Externally Bonded Novel Materials?

Christos G. Papakonstantinou, Christina Kakae and Nikolaos Gryllakis

University of Thessaly, Greece

Abstract—The use of composite overlays to strengthen or rehabilitate existing structural

elements has been investigated over the past few decades. The most common composites that

were used are based on Glass or Carbon fibers impregnated in an organic polymeric matrix,

known as GFRP or CFRP, respectively. Thus, many design codes throughout the world

provide methodologies to calculate the flexural strength of reinforced concrete members

strengthened with externally bonded Carbon or Glass fiber composites. It is essential to keep

in mind that the experimental databases that were used in these codes were based on

experiments conducted on these materials. However over the last years new materials have

emerged, such as steel fibers (SRP/SRG) and basalt fibers (BFRP), as well as textile

reinforced mortars (TRM). In this study the target was to investigate if the analytical models

described in the codes can effectively be used to describe these novel materials as well. In

order to do so, a statistical analysis was conducted to compare experimental results to results

obtained using the methodologies described in the codes. It was found that most codes

perform surprisingly well and in only few cases they do not provide acceptable results.

Abstract—The paper studies estimate ultimate strength and local buckling of circular

concrete filled steel tube (CFST) specimens subjected to axial load using strain gage, force

transducer and displacement sensor. The strain responses of CFST column in testing

procedure and the results of finite element modelling will be used to predict failure modes

when cracks occur in concrete core and deformation increases on steel tube’s surface.

Besides, the principles of Eurocode 4 and AISC 360-10 are used to calculate the critical

buckling stress in comparison with experimental approach and numerical evaluation.

Combining experimental and simulation data can be very useful for diagnostic load rating

and limit, and effective to evaluate the damage on long-term structural health monitoring of

Abstract—Coupled shear walls are efficient in resisting lateral forces induced by winds and

earthquakes. However, it is difficult to construct coupled shear walls particularly because

current design codes require complex reinforcing details within coupling beams. The

objective of this study was to investigate the cyclic behaviour of HPFRCC (high performance

fiber reinforced cement composites) diagonally reinforced concrete (DRC) slender coupling

beams. For this purpose, HPFRCC and conventional reinforce concrete DRC coupling beams

were made and tested. This experimental study shows that HPFRRCC DRC coupling

produced better seismic behaviour than corresponding conventional DRC beams.

Abstract—The objective of this study was to develop simple reinforcement details for

diagonally reinforced coupling beams; reducing transverse steel by use of high-performance

explored. Four coupling beam specimens with length-to-depth aspect ratios of 2.0 or 3.5 were

fabricated and tested under cyclic lateral displacements. The test results revealed that

HPFRCC coupling beams with bundled diagonal bars and widely spaced transverse

reinforcement (one-half the amount of reinforcement required by current seismic codes.)

exhibited excellent seismic performance compared with ordinary concrete coupling beams to

bundled diagonal bars and code-required transverse reinforcement.

Green Tea Extract Inhibits Corrosion of Steel Reinforcing Bars Embedded in Mortar

Ivan Pradipta, Daniel Kong and Joash Tan Ban Lee

Monash University Malaysia, Malaysia

Abstract—Natural antioxidants are organic compounds which are rich in functional groups

with potential electron-donating activity: polar atoms and π–electron rich bonds. Electron

donation by these functional groups may promote an adsorption of natural antioxidants on

steel reinforcing bar (rebar) surface as mixed-type corrosion inhibitors, making the

antioxidants ‘green’ alternatives to commercial inorganic-based corrosion inhibitors. Green

tea is one of the richest sources of natural antioxidants. Therefore, this paper compares the

corrosion inhibition efficiency of green tea extract (GT) against the commercially established

calcium nitrite corrosion inhibitor (CI) on steel rebars embedded in mortar (i.e. reinforced

mortar specimens). Rebar corrosion was accelerated by subjecting the reinforced mortar

specimens to impressed current and cyclic wetting-drying exposure, and the corrosion

development was measured with linear polarization resistance technique. CI and GT were

used as admixed corrosion inhibitors, with the amount of CI and GT added into mortar were

referred to as doses. Doses of CI were calculated based on the ratios of chloride

concentration to nitrite concentration. Nitrite is the ionic component of calcium nitrite, which

is the active constituent of CI. Same dose and same amount of active constituent are ideally

ensured to compare the corrosion inhibition efficiency (IE) of CI and GT. However, at same

inhibitor dose, GT had a lower amount of active constituent than CI, because it had a

ten-times lower percentage ratio of active constituent weight to inhibitor weight (i.e.

concentration, concentration of GT and CI were 3% and 30% respectively). Therefore, two

separate IE comparisons were proposed, based on: 1) same inhibitor dose (volume) and 2)

same inhibitor weight of active constituent. In comparison at same inhibitor volume, same

volume of CI and GT were added into mortar. However, GT had a lower weight of active

constituent than CI due to its lower concentration. On the other hand, in order to compare the

IE of CI and GT at same inhibitor weight of active constituent, concentration of CI was

diluted to the same concentration as GT, which concurrently maintained similar doses

between the inhibitors. Results showed that CI and GT produced a similar IE (51-70%) at the

same weight of active constituent. However, at same inhibitor volume, GT showed a

significantly higher IE than CI (75-80% vs. 14-24%). This significantly higher IE of GT was

contributed by a significant reduction in anodic reaction rate of iron oxidation (βa) and a

significant increase in rebar resistance to external polarization potential/current (Rp).

Meanwhile, the changes in cathodic reaction rate of oxygen reduction (βc) and open circuit

potential (OCP) of the rebars were not significant. These changes in βa and βc without a

significant change in OCP indicated that GT behaved as a mixed-type corrosion inhibitor as

hypothesized, which inhibited rebar corrosion by forming a protective layer on rebar surface

and increased Rp of the rebars. In fact, the significant increase in Rp was the most prominent

factor among the aforementioned factors contributing to a significantly higher IE of GT, as

GT specimens consistently showed a significantly higher Rp than CI specimens, even until

the end of corrosion test (191-221 vs. 56-64 Ω).

Abstract—Recently, materials and structure analysis techniques used in various structures

have been developed and have made remarkable progress. As the design method for

reinforced concrete structures is shifting to the limit state design method, it is necessary to

conduct the limit state assessment. So far, several researchers have evaluated the safety of

many structures covered by the civil engineering field by introducing the limit state

assessment. However, there is a lack of research on bridge piers considering the level of scour.

Therefore, in this study, T-shaped bridge piers with a height of 11.5 m and a width of 2.8 m

installed in underwater ground were selected and the critical condition of bridge pier for 20

seismic waves was evaluated using LS-DYNA. The presence or absence of scouring was also

set as a variable and the level of scour is changed from 0 to 5 meter. As a result of the analysis,

the main fracture was tensile failure at the maximum ground acceleration of 0.2g to 0.4g, and

the maximum ground acceleration after the earthquake was found to be weak as a whole

except compression. Finally, as a result of comparing analysis results according to the

presence or absence of scour, the limit state reaching ratio showed a similar pattern without

significant change.

subjected to the procedures of proper surface preparation and is coated by thermal twin wire

arc spraying process with a consumable arc cored wire of high-chromium steel. As the result

of analyzing sprayed coating layer, it is found that Vicker hardness is high as 901.2 HV,

indicating that the arc sprayed coating has an excellent wear resistance. Black stripes in a

lamellar microstructure have small quantity. The XRD analysis reveals that they are mostly

the oxides of Fe3O4 and FeO with very few Cr2O3 and the oxide content in the coating

analyzed by Nitrogen/oxygen determinator is low as 4.25 wt%. Therefore, the deposited

coating enable to adhere to the surface of shaft well and the coating is strong adequate to

prevent the propeller shaft from corrosion, abrasive wear and erosion. The assessing result of

On Consideration Damage in Drilled Composite Laminates Modified by Nanofibers under

Three-Point Bending Test

Nikbakht

Tafresh University, Iran

Abstract—FRP composites were first adopted as structural materials after World War II and

were applied in the boating and aerospace industries. In the following years, the advantage of

lightweight, high strength, and corrosion resistant composite materials gradually gained the

attention of the civil engineering community. Aided by a growth in research and

demonstration projects funded by industries and governments, the application of FRP

structures in civil engineering has progressed substantially around the world since the late

1980s. Because of the advantages in thermoset-based laminates, such as glass/epoxy

laminates, this type of composites is used mostly in many structures. But, low toughness is

the most disadvantages of these materials. Recently, a novel method was presented in which

nanofibrous mats are interleaved between composite layers.

On the other hand, in many structures like bridges it is necessary to drill composite parts and

joint them by bolts and nuts which make stress concentration around the hole. In this

situation, the condition is suitable for delamination. Therefore, the usage of nanofibers

around the holes can be a good choice for decreasing the damage. In this study, we used

GFRP laminates and all layers were interleaved with Nylon 66 nanofibers. Then, a hole

(diameter of 10 mm) was made in the middle of sample (200*36*5.5 mm3). The drilled

samples were tested under three-point bending tests. According to obtained results, the

damaged area decreased from 526 mm2 to 342 mm2 which shows 35% decrease. Other

damage types like debonding and matrix cracking were also considered by acoustic emission

method.

Plastic Deformations Occuring in Shells with Developable Middle Surfaces during Bending

Marina Rynkovskaya


Abstract—A huge number of investigations on developable surfaces have been made, but the

problem of analysis of plastic deformation during bending was usually out of the path. It is

widespread in practice to make these surfaces with the means of bending. In previous papers,

there has been found no note of the appearance of plastic deformations in a plate which is being

bent into a cylinder. That is why analytical investigation of bending of developable shells is

considered to be of great value. In the paper, analytical formulas which give the opportunity to

determine the bending moments appearing due to parabolic bending of an elastic slab, as well

as formulas for limitations to the slope angle of rectilinear generator of evolvent helicoids

during the process of parabolic bending of an annulus into the given helicoids, are presented.

The author also derived the formulas for determination of the minimum radius of a cylinder

made by bending of a plate without the emergence of plastic deformation in it.

Empirical Stress Intensity Factor Equations for Cracked Steel Plates Repaired with

Double-Sided FRP Patches

Bach Kim Do and Akhrawat Lenwari


Abstract—This paper presents an approach that combines the finite element (FE) modeling and

genetic programming (GP) to provide accurate empirical stress intensity factor (SIF) equations

for center-cracked steel plates repaired with adhesive-bonded double-sided fiber-reinforced

polymer (FRP) patches. Several past studies in recent years independently showed that the

reduction on the SIF of cracked structures after the patch repair is dependent on many factors

such as bonding techniques, material parameters, geometric parameters, environmental factors.

In this study, the SIF of the repaired cracked steel plate was considered to be a function of seven

parameters including the crack length, elastic modulus of FRP material, shear modulus of

adhesive material, dimensions (width, length, and thickness) of rectangular FRP patches, and

thickness of adhesive layers. Empirical SIF equations were created by the data mining process

of genetic programming analyses performed on a database created from the FE results. The SIF

values obtained from these equations were also compared with an analytical equation to assess

whether their ability to perform well on a certain design or not. It was found that the proposed

SIF equations fitted well with the FE results as the squared Pearson correlation coefficients R2

are higher than 0.9. In addition, the correlations between proposed equations and the analytical

equation are approximately 0.8.

Effect of Shrinkage Reducing Admixture on the Strength and Shrinkage of Alkali Activated

Cementitious Mortar

DaNang University of Science and Technology, Vietnam

Abstract—The effect of a shrinkage reducing admixture (SRA) on the mechanical properties

and drying shrinkage of a proprietary alkali activated cementitous material (AACM) was

investigated. Five AACM mortar mixes were prepared. SRA replaced the liquid activator at a

dosage of 0%, 1%, 2%, 4% and 7%. The liquid/binder ratio was 0.38. The samples were cured

in water. The flexural and compressive strengths of all mixes were determined at 1day, 2 days, 7

days and 28 days and the drying shrinkage was determined up to 80 days. The results show that

SRA reduced the shrinkage of AACM mortar by up to 69% after 80 days at 7% dosage.

However, SRA also reduced the compressive and flexural strengths of AACM mortars.

Increasing dosages of SRA reduced the compressive and flexural strength while recording less

shrinkage. Regardless of the dosage of SRA, a unique relationship exists between flexural

strength and compressive strength, which correlates with the data of previous research. The

AACM mortar maintained strength of over 43MPa (greater than 75% of the control mix at 0%

SRA dosage) at 7% SRA dosage, which is classified as high strength in accordance with British

Standard PAS 8820:2016.

Abstract—A visible light-driven activated charcoal adsorption Bi2O3/TiO2 composite

photocatalyst was prepared by an sol–gel method in which activated charcoal acted as a

adsorption to capture metal ions by reacting with bismuth and titanium sources via a

complex polycondensation pathway. The phase and particle size of the photocatalyst were

characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM).The results

revealed that adsorption of Bi2O3 / TiO2 composite powder with activated carbon is not easy

to agglomerate and sinter during the preparation and calcination process, and it has the

advantages of good dispersibility, less agglomeration and uniform particles. The

photocatalytic activity of the as-prepared catalyst was evaluated by degradation of methylene

Assessment of Ecosystem Impacts by Engineering Measures Using the Concept of Building

with Nature

Chien-Yuan Chen and Cr Ku

National Chiayi University, Taiwan

Abstract—A field investigation monitored a river restoration indicator, Kandelia, following

the idea of Building with Nature (BwN). The main objective of the present study is to

understand the relationship between Kandelia growth areas and river patterns; such an

understanding can support river watershed management after engineering measures have

altered rivers. The fitness-existence of Kandelia was evaluated through measurements and

numerical simulations of river discharge, flow velocity, and depth of the river flow. The

ecological survey results showed that although the quantity of Kandelia exhibited periods of

growth and decline, the overall quantity did not change substantially. Even though the

growing area shrank, the number of Kandelia plants did not decline and the biomass density

increased. The flow rate was less than 0.4 m/s, equivalent to static. The numerical

simulations indicated that the downstream sandbar area favored the growth of Kandelia, even

under floodwater after typhoons had brought rain. When typhoons bring rain, the upstream

has a high flow rate, which is not conducive to plant growth. A 5S model and a SWOT

analysis were used for a comprehensive analysis. The indicator Kandelia is a local ecosystem

index of environmental impacts after engineering measures have been conducted. The results

may be used as a reference for river watershed engineering planning and to enhance the

concept of BwN.

Effect of Waste Expanded Polypropylene-Based Aggregate on Mechanical and Thermal

Properties of Lightweight Concrete

Martina Záleská, Milena Pavlíková, Jiří Studnička and Zbyšek Pavlík


Abstract—Resource efficiency and building energy consumption is in recent years an open

question for construction industry. Recycled plastic aggregate can be used as an alternative

aggregate to produce lightweight concrete with low environmental impact of both concrete

and waste plastic and moreover, the obtained lightweight concrete is characterized by

improved thermal insulation properties. In the present study, waste expanded polypropylene

(EPP) aggregate is used for partial replacement of natural aggregate to produce lightweight

cement-based composites containing synthetic coagulated amorphous SiO2 as supplementary

cementitious material. For the applied EPP, basic physical properties were measured and

specific attention was paid to thermal transport and storage properties that were studied in

dependence on compacting time. The effect of EPP content on the mechanical characteristics

and on the thermal properties of developed material was investigated for 28 and 90 days

water cured samples. Composite with incorporated EPP aggregates exhibits enhanced

thermal insulation properties with sufficient mechanical resistance and can be considered as

promising material for building subsoil or floor structures.

Thermal Stability of Lightweight Concrete with Incorporated Regranulated Polypropylene

Aggregate

Lenka Scheinherrová, Martina Záleská, Milena Pavlíková and Zbyšek Pavlík


Abstract—Plastic waste and its low recycling rate make a significant contribution towards

the pollution of the environment. Therefore, it is essential that plastic waste is utilised in

different applications, such as aggregates in concrete. Since the coefficient of thermal

expansion of polypropylene (PP) is significantly higher than for the ordinary concrete, the

resulting mismatch in thermal expansion behaviour of the lightweight concrete can cause

many problems, especially when the external temperatures reach the higher values. In this

paper, an investigation of a manufactured plastic aggregate as a partial replacement for

natural silica aggregate in concrete is presented. For concrete manufacturing, regranulated

polypropylene (R-PP) waste coming from PP pipes production was used for the partial

replacement of silica sand in concrete mix composition by 10, 20 and 30 mass %

respectively. The studied materials were heated up to 120 °C. The basic physical properties

before and after thermal treatment were studied. To analyse the thermal strain and the

coefficient of thermal expansion of the studied materials, the horizontal thermodilatometry

was applied.

Disaster Resilience: A Sustainable Way for Niue

Anthony Freddie and Shenuka de Sylva

Victoria University of Wellington, New Zealand

Abstract—The increasing frequency of natural hazards and disasters, due to climate change,

severely compromises Niue’s fragile economy and its future as a sovereign nation.

Sustainable measures to building resilience and preventing natural hazards from turning into

disasters are urgently needed to reverse Niue’s population decline. Urban renewal and

development projects formulated based on individual’s experiences, outdated attitudes and

approaches, or research conducted through pan-Pasifika and western lenses, and without the

necessary policy controls, have severely compromised the safety of people and property.

The dearth of research on sustainable and resilient planning, design and building practices,

suited to the unique conditions of Niue and its people aggravate this situation. The paper

presents traditional solutions and key findings from community-based studies conducted in

Niue and from disaster preparedness and community resilience research in the Asia Pacific

region. Using a case study approach the paper discusses new and sustainable solutions,

methods and materials that are economically viable and practical, and resonate with local

people, traditions, practices and the place. The aim of the paper is to demonstrate the

opportunities that exist locally for devising and designing sustainable solutions to Niue’s

problems.

University of Sopron, Hungary

Abstract—An energetic model of a typical log home was placed in ten different regions of

Russia and examined the yearly heating energy demand. The building was supplied with

three different types of windows to demonstrate the effect of windows on the heating energy

demand. In a 108 m2 building, changing the 3.5 W/m2K thermal insulation capacity

windows to 1.4 W/m2K and 0.7 W/m2K windows caused an energy saving of 11.9% and

15.9% heating energy respectively. In a heated space reducing the night temperature by 2

degrees Celsius can result in only a 2.7% (1 865 kWh) saving in the colder Magadan region,

while in the Mediterranean Krasnodar, there was a 4.48% (1 151 kWh) saving of the net

heating energy amount. Calculations estimated that Russia possesses a very significant

heating potential savings.

BIM for Existing Buildings: Potential Opportunities and Barriers

Md Aslam Hossain and J K W Yeoh

Nazarbayev Univeristy, Kazakhstan

Abstract—Building Information Modelling (BIM) can play a significant role for better

operation and maintenance (O&M) and building facility management (FM) through the use

of Information and Communication Technologies (ICT) tools. However, most of the existing

buildings have no BIM. Research in creating BIM for existing buildings has received

growing attention in recent years. It is evident from current literature that generating BIM for

existing building is complex, tedious, time consuming and costly. The objective of this

project is to explore potential opportunities and barriers in constructing BIM for existing

buildings. Different techniques used in capturing building data such as imaging, 3D scanning,

Ground Penetration Radar (GPR), 2D scanned plans and so on, have their pros and cons in

terms of high modelling/conversion efforts necessary to construct a semantically rich BIM.

Moreover, most of these techniques are complex; require expert knowledge; core steps are

still manual; face challenges in handling occlusions/uncertain data; and BIM conversion

becomes cumbersome with the BIM’s increasing level of detail (LoD). A systematic analysis

is done on various techniques used in data capturing and how they are converted into a

semantically rich BIM, accuracy of the converted model, interoperability of the generated

BIM in terms of functionality, potential barriers in the automation process and how they can

be overcome.

Flores University, Indonesia

Abstract—The community participation is expected to realize the appropriate housing. But

the financial condition does not support, so that appropriate housing to be half constructed,

which eventually became jammed unsustainable. Lock-brick system building construction

can be implemented for appropriate housing and water infrastructure, such as small ponds

and retaining wall construction. Lock-bricks are made from soil as the main ingredients

added a little cement, thoroughly mixed in dry conditions, has dampened with water to a

level sufficiently moist. Then, pressed with a pressing machine to 60%, forming interlocked

bricks when arranged to form the walls of the liveable house. Columns, beams or retaining

walls can be constructed with this system. Similarly, other water basin infrastructure such as

rainwater catchers-canals can be constructed with this system. Lock-brick systems are used

for a wide range of building infrastructure while considering the strength of the structure, so

as to meet the standards. Various examples of usability have been done for the simple

building liveable housing, student dormitories building, rain water reservoir, runoff

catchment canals, soil retaining walls, and pavement floor. The usability, simple, easy to

make and cheap, making this lock-brick system can support the development of sustainable

infrastructure and built environment.

Plant Species Selection Based on Leaf Vibration Experiments

Mengmeng Li and Jian Kang

Harbin Institute of Technology, China

Abstract—Noise pollution is exacerbated by the rapid urban development. Noise has a serious

impact on both people's life and the cities' ecological environment. The noise should be

controlled immediately. Plants are one of the natural noise-reducing materials, which become

increasingly important and popular. In urban landscape design, it is very important to select

the plant species which have good noise reduction effect. The aim of this paper is to find out

the characteristics of the plants with good noise reduction effect and apply it in urban

landscape design. In this study, an experiment of sound attenuation by plants focusing on leaf

vibration is carried out. This study investigates the vibration of leaves of 6 plant species in a

sound field using a Keyence (IG- 1000 /CCD) Laser Micrometre. The results show that the

vibration amplitudes of plant leaves increase significantly by about 4-12 μm after being

stimulated by sound. In addition, driven by the same sound, the amplitudes of all leaves

varied with the difference of leaf thickness, leaf size and leaf mass. The amplitudes of all

leaves increase with the increase of leaf size and leaf mass, while decrease with the increase

of leaf thickness.

Agent-Based Simulation on Pedestrian Flow Capacity of Narrow Space

Shi Sun, Cheng Sun and Kai Xing


Abstract—The narrow space in the urban pedestrian traffic system is the area which is more

liable to be congested. At present, researches on the maximum pedestrian flow of space

mainly focus on the width of the exit, but there are not sufficient researches on the walking

space with a certain length. The purpose of this paper is to analyze the change of pedestrian

flow capacity of the narrow space with a certain length under the influence of width. The

simulation model of walking behavior was established by Net Logo software. By changing

the space width and the number of pedestrians entering into the space per unit time, the

quantitative relationship between the width of space and the space pedestrian flow capacity

was simulated. In the simulation, the pedestrians' walking behavior is influenced by the target

area, the space boundary and the visible surrounding pedestrian density. The results show

that when the length of the walking space is 30 m and the space width is less than 10.33 m,

the increase of the width will significantly improve the pedestrian flow capacity of the space.

When the space width is more than 10.33 m, the increase of the width will enhance the

pedestrian flow capacity less significantly. The research results can be applied to the design

of the width of urban long and narrow walking space.

Ledras (Ledra Street): Discovering It’s Visible and Invisible Multiple Layers

Gizem Ozturk

Near East University, Cyprus

Abstract—Today, historic preservation and re-use of historic sites are common techniques in

urban development process of cities with rich historical background, which creates many

contradictions and architecturally aesthetical problems. Architects should try to find ways to

understand the problems underneath them and suggest a technique with a continuous

outcome. Researching the multiple layers of this study area will help to discover the

time-space relationship of the existing environment.

Prof. Dr. Semra Aydinli states at her presentation in Boston “Enmeshed experience

motivates us to grasp the multi-sensory qualities of the existing environment. Every place

that has specific spatiality in Istanbul establishes a different integrity for production of

sensation because of its major changes in life and enmeshed experience.”

The disconnection between heritage and contemporary leads this research to search for

possible ways to maintain the environmental value of the Cyprus’ architecture in terms of

quality, continuity, and aesthetical experience. Every historic building, their surrounding, and

society carries its own aesthetical value and identity. The island’s built environment is rich in

variety and each nation has its own unique spatiality in its context. Therefore it is inevitable

to not to come across with enmeshed experiences through a detailed research at any of the

historic quarters of Cyprus. Places contains enmeshed experiences and cultural codes, with

the intention that in this research the chosen method is the bodily experiencing to point out

the identity of the area to identify a new conception of sense and to produce new events.

Bodily experience of Ledra is supported with photography, and maps.

Performance of Concrete Blended with Inhibitors and Slag Exposed to Chloride Environment

Anita N Borade and B Kondraivendhan

S.V. National Institute of Technology, Surat, India

Abstract—In this paper, the performance of concrete with organic inhibitor and slag on

compressive strength and chloride penetration resistance were studied for different

water/binder (w/b) ratios and different curing ages. Organic inhibitor (Amines) was admixed

with cement during the manufacturing process itself of the cement named as corrosion

resistance cement (CRC). The influence of this cement on compressive strength was studied

over different curing ages such as 7, 28, 56, 90, 180 and 360 days. Rapid chloride penetration

test (RCPT) was conducted to explore the resistance to chloride penetration. Half-cell

potential was observed for the period of one year as a measure of corrosion tendency of

reinforced concrete (RC) exposed to 3%, 5% and 7.5% of sodium chloride (NaCl) solutions.

The results of the concrete with inhibitor (CRC) were compared with the concrete with

Portland slag cement (PSC). Significant improvement was observed in compressive strength

with increase in curing ages. The performance of CRC concrete shows remarkable

improvement in corrosion potential (delayed corrosion initiation) as compared to PSC

concrete.

National Institute of Technology, Kochi College, Japan

Abstract—We studied on the anticorrosion effect by applying silane type surface penetrants

on RC degraded by carbonation. Two types of carbonation residue and two types of

environmental conditions after accelerated carbonation were prepared and investigation was

made on the corrosion behaviour of reinforcing bars by applying surface penetrants. As a

result, by blocking water penetration by applying surface penetrants, there was a difference in

anticorrosive effect in the behaviour of half-cell potential, polarization resistance, and

investigation of reinforcing bar corrosion after the end of exposure. From the above, this

paper reports on the possibility of realizing anticorrosion effect by suppressing invasion of

moisture from concrete surface to carbonated RC.

Jenderal Soedirman University, Indonesia

Abstract—Lightweight concrete is a low-density concrete that can be made by replacing

coarse aggregate with artificial lightweight aggregate such as bloated clay, crushed bricks, or

coarse fly ash. This paper presents a study of the influence of carpet waste fiber on the

properties of artificial lightweight aggregate concrete. Tests are performed on 30 concrete

cylinders of 150 mm in diameter and 300 mm in height with various additions of carpet waste

fiber, namely 0%, 0.25%, 0.50%, 0.75%, and 1.00%. Superplasticizer is added at 2% of

cement weight for convenience of casting. We find that using artificial lightweight aggregate

can reduce concrete density to a maximum of 1.94 t/m3. The compressive strength of artificial

lightweight aggregate concrete increases by 17.22% with addition of 0.44% carpet waste fiber,

while the split tensile strength of artificial lightweight aggregate concrete increase by 75.18%

with addition of 0.85% carpet fiber.

Can Tho University, Vietnam

Abstract—This experimental study investigates the develop-ment of compressed stabilized

earth block (CSEB) as an eco-friendly and sustainable wall making material. In the study,

three different types of stabilizers of cement, lime, and wood ash with 5%, 10%, and 15%

replacement of soil are used as stabilizers. Moreover, lime and wood ash were blended with

cement with 2.5%, 5%, and 7.5% of each in order to improve their efficiency. The CSEBs

with dimensions of 300×150×100mm were prepared and cured for 28 days. Finally, the

compressive strength, density, and water absorption of the CSEB were analyzed. Cement

stabilized blocks had the better compressive strength and density and low water absorption

rate but cement is environmentally unfriendly and consumes energy. Lime stabilized blocks

showed good compressive strength and density but high water absorption. While wood ash

stabilized blocks exhibited the poor strength and density and high water absorption but these

properties were improved when wood ash was blended with cement. As the results, the

optimum proportion was found to be L5C (5% lime and 5% cement) or WA5C (5 % wood ash

and 5% cement).

Abstract—This paper presents the experimental results of an investigation on the engineering

properties and durability of high loss on ignition-fly ash concrete fully immersed in 5%

sodium sulfate solution. The fly ash used in this study is a raw material with the loss on

ignition of 15.8%, which is much higher than the upper limitation of 6% as stipulated by

ASTM C618. Eight concrete mixtures were designed with different water-to-binder ratios of

0.35 and 0.45. For each water-to-binder ratio, the fly ash was used to replace 0%, 10%, 20%,

and 30% amount of cement. Test results show that the workability of fresh concrete

increased, while its unit weight decreased with increasing the fly ash replacement level. In

addition, the concrete mixtures with 10% and 20% fly ash content showed the higher

compressive strength, especially at long-term ages, than that of the fly ash-free concrete

mixture. Further, all of the fly ash concrete mixtures exhibited the good quality with

ultrasonic pulse velocity values of higher than 4100 m/s.

Compressive Strength of Concrete with Sewage Sludge Ash (SSA)


Ungku Omar Polytechnic, Malaysia

Abstract—This study was carried out to determine the density and compressive strength of

concrete using Sewage Sludge Ash (SSA) as combination of cement and fine aggregate

replacement. The SSA suggested replacing the cement in the concrete because it has similar

Pozzolanic properties of Ordinary Portland cement (OPC). Besides that, the particle size of

the SSA after incineration process is similar to the fine aggregate that used in the concrete.

The incineration process of the SSA takes 2 hours at the temperature of 1000oC. The sieving

process will take place after incineration process and the SSA will be used as fine aggregate

replacement. The remaining SSA will be grounded with ball mill and used as cement

replacement. In this study, the compressive strength design by using DOE method to

achieved 30 MPa (target mean strength of 46 MPa) at 28 days. The density of the SSA

concrete has higher value compare to control sample because the incineration at 1000˚C will

increase the density of SSA. Previous study shows that 10% of SSA replaces cement in a

concrete give same compressive strength value as control sample and the acceptable

percentage of fine aggregate is between 10 to 25 percentages. Comparatively, the

compressive strength of concrete when SSA used as combination of cement and fine

aggregate replacement also give higher value compare to control sample.

Abstract—Studies about the sewage sludge becoming popular since the sewage sludge can be

treated to produce sewage sludge ash (SSA) which has the potential to replace a percentage

of cement. This study focuses on the flexural strength of the sewage sludge ash (SSA)

concrete for 3, 7 and 21 days of curing relatively to its density. In this study 10 percentages

of SSA was used as a replacement to cement and fine aggregates. SSA had known to exhibits

pozzolanic properties similar to Ordinary Portland Cement (OPC). SSA was also used to

replace the fine aggregates since by products of incineration as the particle size distribution

has similar sizes to fine aggregates normally used in concrete mix. Besides, many studies

also mention that SSA used in concrete may produce lightweight concrete. The SSA was

incinerated at 1000˚C for 2 hours followed by cooling in open air. Some of the SSA was

sieved to be used as fine aggregates and some was grounded to be used as cement. Number

of sample that was prepared for this study was 14 and it was design to achieve compression

strength of 30MPa at 28 days based on DOE method. The flexural strength of concrete for

cement replaced with SSA was lower than the control sample but it has an early flexural

strength. The flexural strength of concrete for fine aggregate replaced with SSA was higher

compared to the control sample.

Modified Pervious Concrete Containing Recycled Asphalt Pavement and Waste Tire Rubber

Thevaneyan Krishta David, RS Chandrasegaran and Sivasan Karan Nair

Universiti Teknologi MARA (UiTM), Malaysia

Abstract—Portland Cement Pervious Concrete (PCPC) can reduce the risk of flash flood by

letting the storm runoff to sip through the voids available in the PCPC hence infiltrate into

the soil. This unique ability of pervious concrete offers advantages to the environment, public

agencies, and building owners by controlling rainwater on site and addressing storm water

runoff issues. Thus, this study was conducted to substantiate the usage of inorganic, cheap

and reusable material namely Recycled or reclaimed asphalt pavement (RAP) and Fine

Crumb Rubber (FCR) in pervious concrete. The primary objective of this study is to compare

the compressive strength, density and the surface infiltration rate of pervious concrete

containing waste tire rubber with pervious concrete that is made up by using natural

aggregate without any enhancement. Standard pervious concrete will consist of natural

coarse aggregates and cement. In this study, RAP will be replacing the natural coarse

aggregates, the same size with the previous research. The modified pervious concrete will

also be mixed with a certain percentage of FCR, replacing certain percentage of the coarse

aggregate. The results of this study indicate that using recycled material could achieve

similar performance as using natural aggregate, hence may reduce the construction cost.

Yamaguchi University, Japan

Abstract—This paper presents an automatic crack inspection system for concrete tunnel

lining based on image processing technique and computer vision. The system includes a

video image acquisition device, an image stitching software, and a crack detection software.

Firstly, the video image acquisition device uses six video cameras and three illuminators

mounted on a steel framework which is capable of sliding from side to top of the inspecting

vehicle to shoot the full surface of the tunnel lining. Secondly, the image stitching software

based on image matching technique was developed to create layout panorama from the tunnel

lining surface images, making it easier to visualize a large and detailed section of the tunnel

lining. Finally, we propose a semi-automatic crack detection software relied on a

combination of image processing technique and interactive genetic algorithm (iGA) to crack

detection for concrete surface images of the tunnel lining. Experimental results demonstrate

the effectiveness of the proposed method.

Development of Ultra High Performance Concrete and Reactive Powder Concrete with

Nanosilica

Rudolf Hela, Lenka Bodnarova and Lukas Rundt

Brno University of Technology, Czech Republic

Abstract—The article is dedicated to the design and production of Ultra High Performance

Concrete (UHPC) and Reactive Powder Concrete (RPC) using silica fume and nanosilica.

Nanosilica and fine steel fibres were used for the production of RPC. Compressive strengths

of UHPC and RPC above 150 MPa have been achieved. It has been demonstrated that UHPC

and RPC can be produced using standard concrete mixing system without the use of

activating mixing and without a special treatment regime during maturing of the concrete.

Aging of the concrete took place in a normal environment, without elevated pressure or

temperature. The aging process at 20 °C allows the use of UHPC and RPC for the

ready-mixed concrete when working on high volume construction projects. Even without

thermal treatment, without the application of solidification pressure and without autoclaving,

RPC reached a compressive strength of more than 180 MPa and a flexural tensile strength

after 60 days greater than 22 MPa. The high tensile bending strength may be considered as

the main advantage of RPC, as the RPC parameters allow, for instance, the use for

pre-stressed structural elements where a high initial strength is also required.

Study on Compressive Strength Prediction on Steam Curing

Nozomi Nakajima, Hiromitsu Koyama, Shin-Ichiro Hashimoto and Shigeyuki Date

Tokai University, Japan

Abstract—Steam curing process is generally adopted for precast concrete products to

improve productivity. For setting reasonable production cycles and selecting economical

formulation, it is important to predict the strength of mortar / concrete at early stage.

Compressive strength estimation by the Maturity method is being widely used in

conventional research. However, it is pointed out that accuracy is relatively low for

estimating the strength of concrete under steam curing condition. Therefore, in this study, a

relation between effective material ages based on the Maturity and Arrhenius’s law and both

initial and long-term strength were evaluated. As a result, it was confirmed that the

Arrhenius's law shows higher estimation accuracy than the Maturity method. Furthermore, it

was confirmed that the prediction method using effective material ages based on the

Arrhenius’s law which takes the activation energy into consideration has higher estimation

The Effect of Different Heights and Angles of Energy Director on Interface Temperature for

Ultrasonic Welding of Thermoplastics

Thang Nguyen Vo and Petr Lenfeld

Technical University of Liberec, Czech Republic

Abstract—Besides technological parameters in the ultrasonic welding process, height and

angle of energy director (ED) also affect the quality of the joint strength owing to its energy

transfer and melting. This paper deals with evaluating the effect of distinct ED heights and

angles of butt-joint on temperature distribution at the weld interface. Experiments were

simulated using transient thermal analysis of Ansys 18 for 3D-samples made of acrylonitrile

butadiene styrene (ABS) and high-density polyethylene (HDPE). The results obtained from

simulation of temperature distribution in various ED heights and angles and welding

amplitudes are presented and compared with each other.

University, South Korea

Abstract—Triboelectric nanogenerator (TENG) is an up-and-coming technology operates

based on the triboelectrification and electrostatic induction to generate the electricity from

various mechanical energy sources. Even though TENG has high power conversion efficiency

in many previous studies but still demand a significant improvement of the output

performance, so the optimization of some key parameters such as tribo-material selectivity,

surface contact area, and nanopatterned morphology is very crucial. Here, we focus on the

output enhancement of TENG based on anodic aluminum oxide (AAO) as a mold and

nanocones polydimethylsiloxane (NC-PDMS) film with simple and cost-effective fabrication

process, high output performance, and long-term stability by soft-lithography technique. The

TENG output improvement is based on the optimization of the structure dimensions of

NC-PDMS distributed on its surface. Follow that varying period and diameter of NC-PDMS

surface is theoretically and experimentally investigated. For the theoretical study, the

NC-PDMS is considered as a viscoelastic material. By this simulation, we calculate the

contact stress for NC-PDMS layers and compared the behaviors by considering the contact

area and stress together (i.e., the product of contact area and stress, called as a contact force).

As the result of a simulation study, the calculated and the experimental data are well matched.

Furthermore, an optimal NC-PDMS with the period and diameter of 125 nm and 60 nm,

respectively, exhibit the open-circuit voltage (Voc) of 568 V and short-circuit current (Isc)

value of ~ 25.6 µA under 10 N pushing force and 5Hz of pushing frequency. The

enduringness test of the TENG device is also conducted to confirm the mechanical stability

and durability. For the windmill integrated TENG model device, the optimal NC-PDMS is

also used and obtained the Voc and Isc values of ~ 200 V and ~ 24 µA, respectively, at the

wind speed of 14-15 m/s.

Synthesis of Cyclic Carbonates from Epoxides and CO2 Using Cu(II) Tryptophan MOF as a

Catalyst

Gyeong-Seon Jeong, Ga-Hyung Kim, Hee-Chul Woo, Kwang-Sun Huh, Dong-Ok Lim and

Dae-Won Park


Abstract—Carbon dioxide is an abundant, non-toxic and thermodynamically stable C1

feedstock. Engaging them for the synthesis of five-membered cyclic carbonates represent an

attractive means of CO2 utilization while viewing from an atom-economic perspective and

also for its splendid applications such as solvents, precursors for synthesis of polycarbonates,

and intermediates in organic material synthesis. Biologically important natural and

biocompatible materials, such as amino acids consists of amino-carboxylate terminals and

side chains functional groups which provide multiple metal binding site in coordination

chemistry. An amino acid-based copper-tryptophan complex was synthesized by an efficient

direct-mixing method under mild conditions, and characterized using several analytical

methods. An amino acid based metal organic framework (MOF) CuTrp was synthesized using

L-tryptophane as a linker, and it was employed as a catalyst to synthesize cyclic carbonates

from epoxides and CO2 in a synergistic manner with a quaternary ammonium salt co-catalyst

(TBAB). A plausible mechanism involves the penta-coordinated Cu center of CuTrp complex

as an active Lewis acidic site, while the nucleophilic bromide anion from TBAB assists in the

ring opening of the epoxide. Furthermore, the catalyst showed good recyclability even after

three cycles.

KOH-Activation Effect on the Electroactivity of Reduced Graphene Oxide/Fe2O3 Electrodes

Seok Kim, Kyu Suk Hwang and Yongchul Chung


Abstract—For the preparation of attractive electrode materials for capacitors, KOH activation

of cheap and available natural precursors, such as coals and pitch-derived carbonaceous

materials has often been used. Chemical modification of graphene nanosheets by KOH was

examined as a way to enhance the specific capacity of graphene nanosheets in supercapacitor.

This method efficiently develops the micropores, and allows various pore size distributions. It

has been shown that some large values of capacitance obtained with KOH activated carbons

are related with important surface functionality. Also, KOH activation improve the wettability

on the carbon surface and they contribute to an additional pseudocapacitance through the

presence of a large amount of oxygenated groups to carbon surface. We fabricated

Fe2O3/KOH-activated rGO composites using a facile two-step synthesis by homogeneous

precipitation and subsequent reduction of the GO. The total specific capacity of

Fe2O3/KOH-activated rGO was higher than the sum of KOH-activated rGO and nanoparticle

Fe2O3. It is thought that the synergistic effect between Fe2O3 and KOH-activated rGO resulted

in a full utilization of electrolyte ions for good charge transfer.

Steam Reforming of Liquefied Oil Derived from Macro Algae over Ni/Mg/Al

Hydrotalcite-Type Catalyst

Yong Beom Park, Hankwon Lim, Hee Ju Ahn and Hee-Chul Woo

Pukyong National University, South Korea

Abstract—Currently, hydrogen is mainly produced from a wide variety of fossil fuels such as

coal, natural gas, petroleum by-products and waste. Hydrogen from renewable resources, such

as biomass, exhibits a promising prospective. Biomass would strongly contribute to

decreasing greenhouse gas emissions due to neutral CO2 balance. Macro algae (seaweed

biomass) have the advantages of high productivity and low CO2 emission compared to land

biomasses, which can be used as a potential source of next generation biomass.

In order to produce hydrogen, we study steam reforming of liquefied oil from macro algae.

Macro algae have high H2O content over about 80%, which it is one of most suitable biomass

for converting to liquefied oil by hydrothermal liquefaction. We investigate the catalytic

performance of Ni/Mg/Al hydrotalcite-type catalyst for steam reforming of liquefied oil

derived from macro algae. The effects of chemical composition on the structure and catalytic

behavior of Ni/Mg/Al catalysts were investigated.

The operating steam reforming conditions were as follows: reaction temperature, 873-1173 K,

liquid hourly space velocity, 0.5-4, steam to carbon (S/C) ratio, 5-30. The catalysts were

reduced in the reactor prior to each reforming reaction under 10% H2/N2 flow for 5 h at 773

K. The gaseous products were analyzed by on-line gas chromatography (HP5890) system

equipped with Hayesep DB column.

Development of Improved Gene Expression Cassette for Glycerol Dehydratase Enzyme in

Pseudomonas Denitrificans

Park

Ulsan National Institute of Science and Technology(UNIST), Korea

Abstract—3-hydroxypropioinc acid (3-HP), an important platform chemical, can be produced

from glycerol through a two-step reaction catalyzed by glycerol dehydratase (GDHt) and

3-hydroxypropionaldehyde dehydrogenase (ALDH). When these enzymes are highly

expressed from multi-copy plasmid(s), recombinant microorganisms can produce 3-HP

efficiently. However, for industrial purposes, the enzymes should be expressed from the

chromosome. In this study, using the recently-discovered novel promoter which is induced by

the target product 3-HP, expression cassette for a GDHt was developed. Gene expression was

modified at transcriptional and translational levels, and the expression efficiency was

evaluated by RT-PCR, protein production, and/or enzyme activity measurements. The GDHt

expression/activity, under both non-induced and induced conditions, could be varied in a wide

range by proper combination of the gene expression control methods.

One Day Visit February 25, 2018 (Sunday) 9:00~17:00

(Tips: Please arrive at LIBERTY CENTRAL NHA TRANG HOTEL before 9:00 a.m. The following schedule

is only for participants who registered the visit & tour. The following places are for references, and the

final schedule should be adjusted to the actual notice.)

1. (9:00) Assemble at LIBERTY CENTRAL NHA TRANG HOTEL

2. Visit Nha Trang Cathedral

Built between 1928 and 1933 in French

Gothic style, complete with stained-glass

windows, Nha Trang Cathedral stands on a

small hill overlooking the train station. It’s

a surprisingly elegant building given that it

was constructed of simple cement blocks.

Some particularly colourful Vietnamese

touches include the red neon outlining the

crucifix, the pink backlighting on the

tabernacle and the blue neon arch and white

neon halo over the statue of St Mary.

3. Visit LongSon Pagoda

Long Son Pagoda, also known as Chua

Long Son, is situated on the foothill of

Trai Thuy Mountain in the city of Nha

Trang. The temple is famous for its

large white Buddha image, which sits

atop the mountain crest and can be seen

from anywhere in town. Built in 1886

in the style of Taoist architecture, Long

Son Pagoda has been home to many

high-ranking Buddhist monks and the

Vietnam Buddhist Studies Foundation

was founded here in 1936.

After being destroyed by a cyclone in

1990, the whole complex was rebuilt at the present site further down the hill. In its attempt to recreate the

exact replica of the old temple, Long Son underwent many restorations and additions, interrupted at times

by the Vietnam War and civil unrests. The white Buddha image was constructed much later in 1964. Today,

Long Son Pagoda boasts beautiful and unique turn-of-the-century Taoist architecture characterised by the

embellishment of mythical animals and sculptures of Taoist gods. It is also a working monastery complete

with a school for monks in its grounds. An impressive three-tier roofed entrance, decorated with mosaic

dragons, leads to the large temple grounds decorated by potted topiary.

4. Have Lunch Together

5. Visit PoNagar Cham Towers

Built between the 7th and 12th

centuries, these impressive Cham

towers are still actively used for

worship by Cham, Chinese and

Vietnamese Buddhists. Originally

the complex had seven or eight

towers, but only four remain, of

which the 28m-high North Tower

(Thap Chinh; AD 817), with a

terraced pyramidal roof, vaulted

interior masonry and vestibule, is

the most magnificent.

6. Visit HonChong Promontory

Hon Chong complex has

included large rocks stacking

each other for centuries. This is

a large square rock block lying

on a flat and huge rock. The

side overlooking the sea houses

vast hand-shaped indentations.

The promontory has long

become a tourist spot attracting

tourists to Nha Trang city. Here,

tourists can feel Hon Chong

Promontory as the intersection

of the mountain and sea. Just a few steps, tourists can touch the sea or the foot of the hill. In particular,

going to Hon Chong, tourists also have a chance to hear many interesting stories about the promontory

among charming natural scenery. Hon Chong Promontory is becoming one of the new enchanting tourist

attractions in Nha Trang.
