The agreement to arbitrate is a central feature of commercial arbitration and the lack of a valid arbitration agreement is recognised as a reason why any arbitral award may not be recognized as binding by the courts or may be set aside. The purpose of this paper is to clarify the China's present arbitration law and practice in respect of determination of the validity of international commercial arbitration agreement. Most arbitration laws only require an arbitration agreement to be "in writing". But the arbitration law of the China require an arbitration agreement shall contain the following: 1. The expression of application for arbitration. 2. Matters for arbitration. 3. The arbitration commission chosen. And China's present arbitration law and practice in respect of determination of the validity of international commercial arbitration agreement are somewhat different from the other nations.

Heterotrimeric GTP binding proteins (G proteins) mediate signals generated by neurotransmitters and hormones Among G proteins, Go is found in a large quantity in brain and growth cone membranes of neurons. In spite of its abundance in neurons, the role of Go is not fully understood. In our previous study, we identified promyelocytic leukemia zinc finger protein (PLZF) as an interacting partner of alpha subunit of Go ($Go{\alpha}$) and confirmed their interaction employing several biochemical assays. To date, it is reported that PLZF functioned as a cell growth suppressor and a transcription repressor. To determine effect of $Go{\alpha}$ and PLZF interaction on the cellular function of PLZF, we performed luciferase reporter gene assay and BrdU incorporation assay. Co-expression of $Go{\alpha}$ and PLZF synergistically increased the effect of PLZF alone. These results suggest that $Go{\alpha}$ may act as cellular activator of PLZF. This novel feature of Go may provide insights into understanding diverse role of Go-coupled receptor as well as its cellular actions.

Targeted glycoproteomics is an effective way to discover disease-associated glycoproteins in proteomics and serial affinity chromatography (SAC) using lectin and glycan-targeting antibodies shows glycan diversity on the captured glycoproteins. This study suggests a way to determine glycan heterogeneity and structural analysis on the post-translationally modified proteins through serial affinity column set (SACS) using four Lycopersicon esculentum lectin (LEL) columns. The great advantage of this method is that it differentiates between glycoproteins on the basis of their binding affinity. Through this study, some proteins were identified to have glycoforms with different affinity on a single glycoprotein. It will be particularly useful in determining biomarkers in which the disease-specific feature is a unique glycan, or a group of glycans.

Multihoming is an attractive feature for mobile nodes (MN) equipped with multiple network interfaces in a converged networking environment. However, the current standard Mobile IP (MIP) lacks support for multihomed MNs. Accordingly, this paper presents an immediate solution to resolve the problems of multihomed MNs in a UMTS and WLAN interworking system. The interworking system is based on a hierarchical architecture according to the UMTS and WLAN coverage characteristics. The MIP is only operated in the WLANs, and not in the UMTS, allowing the MIP to be used for multihomed MNs with minimal modifications. In addition, MIP binding filters are used to realize the advantages of multihoming, enabling different traffic flows to be transmitted simultaneously through different interfaces. The overall design aims to minimize the modification to the MIP and impact on existing UMTS and WLAN systems. We evaluate the performance of proposed scheme using an OPNET simulator.

This paper describes an electrochemical immunosensor for simple, fast and quantitative detection of a urinary hippuric acid which is one of major biological indicator in toluene-exposed humans. The feature of this electrochemical system for immunoassay of hippuric acid is based on the direct conjugation of ferrocene to a hippuric acid. With the competition between the ferrocene-hippuric acid complex and hippuric acid for binding to the anti-hippuric acid monoclonal antibody coated onto gold nanoparticles, the electrical signals are turned out to be proportional to urinary hippuric acid in the range of 0.01-10 mg/mL, which is enough to be used for the point-of-care. The proposed electrochemical method could extend its applications to detect a wide range of different small molecules of antigens in the health care area.

Jeonju-Jang is the wood furniture that was made in Chonbuk Jeonju province during the Joseon Dynasty, and was used by middle-upper social classes. It has value as a local cultural heritage because it has unique characteristics in terms of the shape of the furniture, the metal ornament and various functions are integrated in accordance with user's requirements. Therefore, the purpose of this study is to define the structural characteristics of the Jeonju-Jang through case studies of 16 existing artifacts in order to preserve and inherit the value as local cultural resources. The conclusion is as follows. First, Jeonju-Jang in the late period of Joseon Dynasty that is made up of one board to the bottom with the binding of the board. and the front wall, the Juibyuckkan and the Meoruemkan are omitted or made small, so the structure of the surface is simple. There are three or four drawers under the Cheon pan(top plate). There are drawers and shelf inside the hinged door. In the case of a two-layer type, there is a Gaegumeong type door which has half of one side hinged. Second, Jeonju-Jang of the Japanese Ruling Era had a Juibyuckkan by frame binding and an increase in the number of Meoruemkan. and it had independent legs. The Cheon-pan(top plate) was more left and right than both sides. Third, in the late Joseon Dynasty period as a feature of the metal ornaments, cast iron and yellow brass were used as materials. In the Japanese Ruling Era, nickel was mainly used. Various patterns were engraved and the number increased, and it became gorgeous surface as a whole.

In recent years, there were frequent exogenous contagious diseases in Eastasia like SARS(severe acute respiratory syndrome), Avian influenza, Swine influenza, MERS etc. But there are various interpretations about their pathological differentiations and lead to controversy to diagnosis and medicinal use. So there needs universal and consistent understanding methods. Several conclusions are obtained from the research on differentiation theories of various epidemic diseases. Essential elements of differential diagnostic system are pathogen, characters and matters of disease and loci, especially three yin and three yang has close affinity with constitutional features or body shape. Binding these 3 categories, an integrated differentiation 3 dimensional coordinates are made. Out of these, each elements of 3 pathogen-axial lines are related with names of exogenous disease, and those of 3 feature-axial lines are related with 8 principal patterns. And those of 3 locus-axial lines implicating therapeutic method are related with steps and location of exterior and interior, 3 yin 3 yang, Defense, Qi, Nutrient and Blood, five viscera and six bowels and tissues. Additionally, 3 lines of each axis consist of factors which have their own affinity each other, so classification of pathogen, feature, locus of disease has layered interconnectedness. This classification system is included in constitutional features of individual patient. Afterwards, these cognitive structure can be used as a general theory guiding method of therapy, prevention and aftercure healthcare.

Biotin에 강한 결합 친화력($K_D=10^{-14}M$)과 함께 streptavidin의 tetramer 특징은 VHH 항체를 streptavidin에 융합시키게 하여 biotinylated horseradish peroxidase를 사용하는ELISA 와Western blot analysis 등의 면역분석법에서 VHH 항체의 항원결합력을 증가시키는데 응용 가능하다. 이를 응용하기 위해 우리는 Streptomyces avidinii 염색체 DNA로부터 PCR을 통해 streptavidin유전자를 증폭하고 이를 green fluorescent protein항원에 특이적으로 결합하는 8B9 VHH 항체유전자에 융합시켰다. 대장균에서 수용성 융합단백질로 발현시키기 위해 pUC119 플라스미드에 기초한 발현시스템을 사용하였다. 즉 lacZ promoter를 사용하여 IPTG에 의해 단백질발현을 유도하게 하였으며, 아미노말단에 pelB leader를 두어 발현된 단백질의 periplasmic space로 이동하게 하여 수용성 단백질형태의 분비를 촉진하였으며 카르복시말단에 6개의 polyhistidine tags를 두어 $Ni^+$-NTA-agarose column을 사용하여 발현된 단백질을 정제하였다. Streptavidin이 biotin에 강하게 결합함으로 대장균에 독성을 나타냄에도 불구하고 본 수용성 융합단백질은 성공적으로 발현되었다. SDS-PAGE에서 가열하는 경우 변성되어 30.6 kDa를, 가열하지 않는 경우에는 자연 상태의 122.4 kDa을 나타내었다. 이는 8B9 VHH항체에 융합된 streptavidin moiety에 의해 monomer subunit가 비공유결합으로 tetramerization됨을 제시해준다. 또한 본 융합단백질은 ELISA와 Westernblot analysis에서 보여진 것처럼 parental streptavidin과 유사한 biotin결합력과 green fluorescent protein항원 결합력을 모두 나타내었다. 결론적으로 streptavidin에 융합된 8B9 VHH 항체형태의 융합단백질은 대장균에서 수용성 tetramer로 성공적으로 발현 및 정제되었으며 biotin과 green fluorescent protein 항원에 동시에 결합함으로써 tetrameric and bifunctional VHH 항체제조의 가능성을 제시해주었다.

본 연구에서는 울금의 주요 성분인 커큐민과 나노 마이셀링 기법을 적용한 신규 조성물인 염화 커큐민(NMC)의 트랜스타이레틴(TTR) 단백질 활성 부위에 대한 in silico 분자 결합 친화도를 비교 분석하였다. 우선 NMC신규 조성물의 결정학적 구조를 광학 및 전자현미경을 활용하여 관찰하였을 때, 나노 마이셀링 적용 NMC 결정은 일반 천일염에 비하여 색상 및 질감이 전체적으로 균일화 되었고, 천일염과 NMC성분이 강하게 일체화되어 기간이 상당히 경과 되더라도 쉽게 분리가 되지 않는 고기능성 안전성 구조물이 형성되었다. TTR단백질의 3차원 구조 활성 부위에 대한 in silico 분자 결합 친화도는 NMC가 일반 커큐민에 비하여 상대적으로 높은 결합 친화도를 나타나었고, pharmacophore 모델링 분석에서도 NMC가 일반 커큐민에 비하여 TTR 활성 부위에서 현저하게 pharmacophore 각도의 차이가 나타났었으며 패턴 또한 밀집된 특징을 나타내었다. 결론적으로, 나노 마이셀링 적용 NMC가 일반 커큐민에 비하여 상대적으로 우수하게 TTR 단백질의 활성 부위에 결합하는 것을 확인하였고, 이는 TTR 활성에 의해 유도되는 질병 조절 물질로의 적용 가능성이 있다고 판단된다. 결론적으로 일반 커큐민과 같은 생리 활성 효능 성분에 나노 마이셀링 기법을 적용하므로서 효율적인 결합 타깃 단백질 활발 조절 및 이러한 성분을 활용한 기능성 식품 산업에 나노 마이셀링 기법을 효율적으로 적용할 수 있음을 확인하였다.
