혈압저하작용, 이뇨기능 등의 다양한 생리활성을 나타내는 γ-amino butyric acid(GABA)를 고농도로 생산하는 유산균인 Lactobacillus sakei B2-16을 이용하여 GABA의 산업적 생산 배지를 연구하였다. L. sakei B2-16의 최적 상용 배지는 Lactobacilli MRS 배지였으며, Lactobacilli MRS 배지에 1% mono sodium glutamate(MSG)를 첨가하고, L. sakei B2-16을 배양했을 때 MSG의 99.3% 는 GABA로 전환되었다. MRS 배지를 기본으로 최적 배지조성을 검토한 결과, 탄소원으로 4% sucrose와 질소원으로 1% yeast extract를 첨가하였을 때 균체 증식과 GABA 생산량이 가장 우수하였다. 산업적 배지를 확립하기 위하여 미배아를 온수 추출하여 얻은 추출액 배지에 L. sakei B2-16을 배양한 결과, 7%의 MSG를 100% GABA로 전환시켰으며, 미배아 추출액을 이용한 배지는 산업적 생산용 배지로의 응용이 기대된다.

This study investigates Bi2O3-B2O3-BaO-ZnO glass with variations of the Co3O4 content (0.25,0.5,1,and 2wt%) and the interaction between transparent dielectric and Ag electrodes heat-treated at 500-560oC for30min. The glass transition temperature, softening temperature and thermal expansion coefficient were432oC, 460oC and 81.4×10-7/oC, respectively. The transmittance of 0.25wt% Co3O4 to which dielectric wasadded was highest and was decreased due to coloration with the addition of more than 0.25wt%. However,without Co3O4, the transmittance of the transparent layer was decreased due to the formation of Ba5Bi3;however, the occurrence of the crystal phase decreased as a result of the addition of Co3O4. The amount ofCo2+ ions increased as the Co3O4 increased. With a maximum of Co3+ ions, the highest transmittance wasobserved.

The 2-1 and 5-4 transitions of SiO have been observed toward the Sgr B2 region, including the Principal Cloud(the GMC containing Sgr B2(M)) and its surroundings. The morphology and velocity structure of the SiO emission show a close resemblance with the HNCO Ring feature, identified by Minh & Irvine(2006), of about 10 pc in diameter, which may be expanding and colliding with the Principal Cloud. Three SiO clumps have been found around the Ring, with total column densities Nsio ~1x1014 cm-2 at the peak positions of these clumps. The fractional SiO abundance relative to H2 has been estimated to be ~(0.5-1)X10-9, which is about two orders of magnitude larger than the quiet dense cloud values. Our SiO observational result supports the existence of an expanding ring, which may be triggering active star formations in the Principal Cloud.

The main purpose of this study is to identify the factors that affect purchase intention in B2C cooperative buying. The purchase intention is described in terms of participation frequency and total sum of purchasing on cooperative buying. It is very interesting that the influencing factors are not identical when two dependent variables. participation frequency and total sum of purchasing, are used. Residential area, sex, and product variability were selected as key influencing factors for the former case. On the other hand, residential area, price, and product quality were selected as key influencing factors for the latter case. Finally, it is worth while to stress that online community, one of the factors considered, will be a key factor as market of cooperative buying is getting bigger.

As e‐commerce in the Internet environment is settled as a main pattern of transactions among businesses, there are increasing demands for standardized B2B business models to break away from closed structure and enhance outsourcing capabilities. With the advancement of modularization, which is a major trend in the automobile parts industry, the role of finished car manufacturers has been shrunk and primary cooperative companies has been growing in their importance and company size. In this situation, it is strongly required to establish online B2B portals for cooperation with small part manufacturers. Thus the present study purposed to implement WebService by mapping existing EDI standard forms using ebXML platform, which is regarded as the international standard of B2B e-commerce. The implemented WebService facilitates interaction and integration with existing applications using REST technology, which was applied in order to solve problems in ORPC-based distributed application environment including single vendor solutions, the requirement of high‐performance environment based on management network and firewall/proxy problem.

SiO2-B2O3 막의 수소/질소 혼합 기체 분리 특성은 기체분리 압력을 달리하여 조사하였다. 25{℃, ΔP 155.15cmHg에서 수소/질소 혼합 기체를 분리하여 본 결과 SiO2-B2O3 막의 수소에 대한 real separation factor(α)는 4.68이었다. 그리고 투과셀의 압력차(ΔP)값이 증가할수록 real separation factor(α), head separation factor(β), tail separation factor((equation omitted))값이 증가하였다.

The H2S 22,0 - 21,1 line emission is observed to be strongly localized toward Sgr B2(M), and emissions from other positions in the more extended SgrB2 region are almost negligible. H2S is thought to form effectively by the passage of the C-type shocks but to be quickly transformed to SO2 or other sulfur species (Pineau des Forets et al. 1993). Such a shock may have enhanced the H2S abundance in Sgr B2(M), where massive star formation is taking place. But the negligible emission of H2S from other observed positions may indicate that these positions have not been affected by shocks enough to produce H2S, or if they have experienced shocks, H2S may have transformed already to other sulfur-containing species. The SO2 222,20 - 221,21 line was also observed to be detectable only toward the (M) position. The line intensity ratios of these two molecules appear to be very similar at Sgr B2(M) and IRAS 16239-2422, where the latter is a region of low-mass star formation. This may suggest that the shock environment in these two star-forming regions is similar and that the shock chemistry also proceeds in a similar fashion in these two different regions, if we accept shock formation of these two species.

웹 서비스는 서비스의 탐색(discovery), 합성(composition) 또는 관리(management)와 같은 다양한 요구 조건을 처리하고, 특히 WSDL이나 UDDI는 구문적 수준에서 서비스의 기술과 탐색을 위한 기능만을 제공하고 있기 때문에 컨텐츠에 포함된 의미를 처리하는데 많은 한계가 있다. 본 논문에서는 이러한 문제점을 해결하기 위하여 온톨로지 기반 시맨틱 웹을 이용하여 기업간 전자거래 서비스를 자동으로 합성처리 하는 합성규칙과 모델을 제안하여 각 합성단계에 따라 제품거래 서비스의 구문적인(syntactic) 특징과 의미적(semantic)인 특징을 비교하여 제품거래의 합성 서비스를 합성 할 수 있도록 합성 모델을 제시한다.

This paper suggests the process of performance measurement system development for B2B e-Marketplace using BSC (Balanced Scorecard). As the first step, main features and factors affecting performance of e-Business company and especially of B2B e-Marketplaces were derived based on the literatures. For the 2nd step, the nonnative performance measurement model for B2B e-Marketplace was suggested. Especially, the research range that the model covers is restricted to the neutral and systematic sourcing B2B e-Marketplace. And, the performance measurement model was based on BSC, for the BSC is very powerful and sound tool among all the available performance measurement systems. Also, the model was based on the AHP (Analytic Hierarchy Process) to make the model more structured, and to draw weights of performance measures from experts

With the recent trends of electronic commerce moving from B2B to B2B, Collaborative Product Commerce (CPC) is widely adopted as a part of B2B in the virtual collaborative environment. This paper proposes an integrated CPC framework supporting collaborativ

The official ebXML white paper states that the vision of ebXML is to create a single global "electronic marketplace" where enterprises of any size and in any geographical location can meet and conduct business with each other through the exchange of XML based messages. ebXML is an end-to-end solution between ebXML compliant software. However, B2B e-marketplace business models do not include such end-to-end B2B models that trading partners exchange XML or EDI based messages with each other. Therefore, this paper aims to clarify the difference between ebXML and B2B public e-marketplace as well as to discuss the application of ebXML to public e-marketplace for making a right decision to adopt a new B2B e-business technology.

This paper presents the business model and system functionalities of a B2B e-marketplace solution that not only can overcome some problems of the public e-marketplace, but also can be applicable to both public and private types of e-marketplaces. This sol
