While it is the DNA sequence which holds the information deciding the amino acid sequence of the resulting proteins, in order to fully comprehend the entirety of the structures and functions of proteins in an organism, further information than just the amino acid sequence is a necessity. Of the numerous modifications that occur on proteins, glycosylation is a field in the limelight in post-genome research. In February of 2003 the Massachusetts Institute of Technology published an article on “10 Emerging Technologies that will change the world” – glycobiology was selected in the field of biotechnology, therefore its potential and merit acknowledged, and since then research in the field has been burgeoning in the USA and Japan. Before Dr. Gerald Hart of Johns Hopkins University School of Medicine had discovered the existence of nuclear and cytosolic O-GlcNAc modification in 1984, complex carbohydrates were known to exist only in the endoplasmic reticulum, the Golgi apparatus and outside the cell, thus until now researches conducted on complex carbohydrates were limited to the endomembrane system. However, when O-GlcNAc modification was revealed to be closely involved with diabetes, Alzheimer’s disease and tumorigenesis, as well as that it competes against phosphatase for the modification sites on serine and threonine residues, the biological functions of O-GlcNAc modification, more specifically its role in cell signal transduction became the focal point of researches on molecular and individual levels. 3% of all glucose that enter the cell pass through the hexosamine biosynthesis pathway and are converted into UDP-GlcNAc. Utilizing UDP-GlcNAc as its substrate, O-GlcNAc modification is a modification unlike its predecessors in that its level is dynamically regulated by O-GlcNAc trasferase (OGT) which attaches O-GlcNAc onto target proteins, and reversibly removed by O-GlcNAcase (OGA). Proteomics and glycomics research technologies have determined that over 1,800 proteins are modified by O-GlcNAc, but due to a slowed development of technological infrastructure with which to recognize and study the function of O-GlcNAc modification, locating O-GlcNAc modification sites of a protein has only recently become an active field of research. There are only around 100 proteins of which the exact modified amino acid and its resulting functions are known – a vastly small number compared to the number of proteins known to possess O-GlcNAc modification as aforementioned.

In this study, waste natural fibers and natural adhesions were used to prepare an environmental biodegradable nonwoven type mulching material. Especially, the nonwoven mulching with higher content of cotton shows a improved biodegradation. Also, the physical properties of nonwoven mulching with different ratios of cotton/rayon were studied. It was found that the degree of biodegradation was controlled by the type of nonwoven materials and adhesions.

본 연구에서는 양자 역학 계산 이론 중 하나인 Density Functional Theory (DFT)를 사용하여 $Pd/Pd_3Fe$ 촉매 표면에서 개미산(HCOOH) 분해 반응으로부터 수소를 생산하는 반응 메커니즘을 분석하였다. 기존 연구에 따르면, 단일 원자 촉매 중에서 개미산 분해 반응에 가장 높은 수소 생산성을 기록하는 원자는 Pd 촉매이지만, 부 반응으로 생산되는 CO가 Pd에 독성을 띄우기 때문에 Pd 촉매의 성능을 저하시킨다. 이러한 단점을 극복하고자, Pd를 기반으로 Pd와 Fe를 3:1로 합금하여 $Pd_3Fe$가 코어(core) 형태로 존재하고 Pd가 표면에 위치한 core-shell $Pd/Pd_3Fe$ 촉매를 설계하여 개미산 분해 반응에 의한 수소 생산 속도를 계산하였다. 순수 Pd촉매 보다 $Pd/Pd_3Fe$ 촉매의 수소 생산 반응의 활성 에너지가 감소하였다. 그 이유는 Pd와 Fe가 합금화 되면서 $Pd_3Fe$의 격자 상수가 $2.76{\AA}$로 줄어 들어 HCOO의 흡착에너지를 0.03 eV 감소시켰고, Fe에서 표면 Pd로 전자가 이동하면서 표면 전자 구조가 변화하여 HCOO의 흡착에너지를 0.29 eV 낮추었기 때문이다. 본 연구에서 제안하는 결과를 바탕으로 추후 개미산으로부터 수소 생산이 더 용이한 새로운 촉매 설계 메커니즘을 제안하고자 한다.
Formic acid has been known as one of key sources of hydrogen. Among various monometallic catalysts, hydrogen can be efficiently produced on Pd catalyst. However, the catalytic activity of Pd is gradually reduced by the blocking of active sites by CO, which is formed from the unwanted indirect oxidation of formic acid. One of promising solutions to overcome such issue is the design of alloy catalyst by adding other metal into Pd since alloying effect (such as ligand and strain effect) can increase the chance to mitigate CO poisoning issue. In this study, we have investigated formic acid deposition on the bimetallic $Pd/Pd_3Fe$ core-shell nanocatalyst using DFT (density functional theory) calculation. In comparison to Pd catalyst, the activation energy of formic acid dehydrogenation is greatly reduced on $Pd/Pd_3Fe$ catalyst. In order to understand the importance of alloying effects in catalysis, we decoupled the strain effect from ligand effect. We found that both strain effect and ligand effect reduced the binding energy of HCOO by 0.03 eV and 0.29 eV, respectively, compared to the pure Pd case. Our DFT analysis of electronic structure suggested that such decrease of HCOO binding energy is related to the dramatic reduction of density of state near the fermi level.

Fall-arrest systems(maximum arrest force and allowable free-fall) have been widely applied to provide a safe stop during fall incidents for various industrial activities. Fabric structure affects on the mechanical properties of shock energy absorber. The object of this study is to perform the basic research for the evaluation of the capacity of fall arrest energy absorber in relation to the different interlace yarn density. In this work, pack style energy absorber was prepared by weaving 10 types(Interlace yarn density used high tenacity PET 1000D : 60, 59, 58, 57, 56, 55, 54, 53, 52, 51). The paper presents the results of theoretical investigations of the performance of adjustable absorber during fall arrest. Dynamic load tests based on the EU fall protection equipment standard(CE : EN355:2002) were conducted. Results showed that the maximum arrest force by dynamic load test of energy absorber was satisfied with global standard(below 6,000N). Also, Maximum allowable free-fall of energy absorber showed below 1.75m.

Work-related falls are a major problem in the construction and roofing industries. To avoid serious injury to the worker caused by high decelerations or forces, different systems to absorb the energy of a fall are implemented in personal protective equipment. In this study, shock energy absorber lanyard protection tube was prepared using high tenacity PET fiber, P-aramid fiber, and UHMWPE fiber, respectively. Dynamic load test and static load test, bursting strength test based on the Korea fall protection equipment standard(Korea Occupational Safety & Health Agency standard 2013-13) or conformity European safety test(CE : EN355) were conducted. Especially maximum arrest force by dynamic load test of energy absorber showed below 6,000N.

With a new method of applying chitosan and alginate onto cellulose, multi-coated cotton fabrics with chitosan and alginate were prepared and characterized. To coat cotton with chitosan, raw cotton was dipped in chitosan solution, mangled of 1kgf/$cm^2$, neutralized in 2 wt% NaOH soluton, washed, and dried at $60^{\circ}C$ oven. The chitosan-coated fiber was dipped in sodium alginate solution, 1kgf/$cm^2$ mangled, neutralized in 2 wt% $CaCl_2$ solution, washed, and dried at $60^{\circ}C$ oven, resulting in CCAC(coated cotton with chitosan and calcium alginate skin) fiber characteristics. Excellent absorbancy of distilled water and saline solution was observed by the absorption test on cotton fabric treated with CCAC(0.5 wt% calcium alginate) and 0.5 wt% calcium alginate respectively. The SEM photograph confirmed the uniform coating on the cotton fabric surface.
