B2B EC 플랫폼에서의 구매 프로세스를 지원하기 위한 구매자 쇼핑카트는 위치에 따라 판매자쪽의 s-cart, 중개자쪽의 i-cart, 구매자쪽의 b-cart로 분류할 수 있다. 본 논문에서는 B2B EC에서의 구매자 쇼핑카트의 요구기능을 사용자 식별, 상품정보수집, 물품정보제거, 주문처리, 지불처리, 진행사항 추적, 구매기록, 구매의사결정지원, 전자구매시스템에 구매기록 전송 등 9 가지로 제시하고, 이러한 관점에서 각 구매자 쇼핑카트에 대한 정성적인 비교 분석을 시도한다. 그리고 효율평가모델 제시를 통한 정량적인 분석과 상장기업 30개사의 구매직원에 대한 인터뷰를 통한 변수값 설정을 통해서 B2B EC환경에서의 구매자 쇼핑카트의 효율성 평가를 시도한다. 본 논문을 통해서 B2B EC환경에서는 b-cart 방식의 구매자쇼핑카트 방법이 효율적인 플랫폼임을 제시한다.

B2C EC has two kinds of perspectives such as technology-oriented and trust-oriented perspectives. As lots of fraud damages on the B2C EC have been reported every day, the trust-oriented perspective receives lots of attention. In this study, an integrative typology for developing and validating trust measures for B2C EC proposed by McKnight et al.(2002a) and McKnight and Chevany(2002b) has been used for trust-oriented perspective, and the TAM(technology acceptance model) model proposed by Fred Davis in 1985 has been used for technology-oriented perspective. An research model had been developed by using the 4 factors of an integrative typology and 5 factors of the TAM model such as perceived usefulness, perceived ease of use, trust beliefs, intention, and actual transaction. All 13 hypotheses had been proposed from this research model and tested by field study. 12 hypotheses, including the 4 f actors of an integrative typology as antecedents on trust beliefs, were significant, whereas the hypothesis 5 on the relationship between structural assurance and perceived ease of use was insignificant. Structures on B2C EC like guarantees, regulations, promises, legal recourse, or other procedures seemed to be difficult to B2C EC customers. Therefore, these structures should be developed more easier to B2C EC customers.

The alkali extraction of anticoagulant from a clove revealed 3-to 6-fold more effective than hot-water extraction. The highest anticoagulant activity was found with 0.1 N NaOH at 7$0^{\circ}C$. The anticoagulant fractions from a clove, EC-2B and EC-2C were separated by alkali extraction, ethanol precipitation, cetavlon treatment, and ultrafiltration. The anticoagulant activities of these two fractions were, respectively, 6.57 and 8.63 times higher than those extracted with hot-water. As of the sensory evaluation, boiled pork added with EC-2B fraction revealed similar sensory acceptability to raw clove material, while EC-2C fraction had low sensory acceptability due to a mild chemical odor. Antibacterial characteristics against pathogenic microorganism of both fractions were confirmed in the control strain. The inhibitory effect of growth by EC-2B was noticed above 0.016% in S. aureus. Also, EC-2C showed the inhibitory effect at 0.004% in both E. cole and S. aureus control strains.

Nowadays, the spreading of electronic commerce using internet demands a lot of change in business environments, as it is called B2B. Especially, the B2B based EC have a majority rates over the 10% of whole EC markets. As the approach way and the core axis of e-Marketplace in B2B markets are changed more by the business section and industry section than by each company sections, all of the world leading company including Korea are trying to take a prior occupation in e-Marketplace market. In korea, B2B e-Marketplace are mainly leaded by ministry of commerce, industry and energy which choice the company, run a trial managed company. Above MOCIE efforts are now having a lot of trial and error. Accordingly, this thesis are focused on researching the construction trends of B2B e-Marketplace, the future prospects, and promotion plans.

According as Internet based EC(Electronic Commerce) has been activated, More requirements for exchanging digital documents are being proposed in B2B(Business to Business) and B2G(Business to Government) environments. However, the documents can not be processed automatically, because the structures of documents in each site(companies, central/local governments) do not match. Therefore, W3C(World Wide Web Consortium) has proposed XML(eXtensible Markup Language) DTD(Document Type Declaration) technology to support structuring documents. The XML DTD technology can support interoperability between EC sites. And, XML DTD based documents can be processed automatically in every sites. They will improve efficiency of services in B2B and B2G environments. In this paper, we propose interoperable DTD architecture and IDEP(Interoperable DTD Exchange Protocol) protocol which supports searching DTDs and exchanging DTDs. This technology can popularize DTDs and digital documents.

Time domain reflectometry (TDR) is a newly developed method for measuring simultaneously solute concentrations and volumetric water content of soil. Bulk electrical conductivity ($EC_a$) of soil is obtained from TDR signal using several equations proposed, and electrical conductivity of soil solution ($EC_w$) can be calculated using the linear relationship $EC_a=EC_w\theta(a\theta+b)+EC_s$ between $EC_a$ and $EC_w$ at constant soil water content. The objectives of this study were to evaluate $EC_a$ proposed by several workers and to obtain the empirical constants (a, b, and $EC_s$) for $EC_w$ of the soils from A, Bl, and B2 horizon of an agricultural field (Coarse loamy, Fluvaquentic Eutrudepts). The $EC_a$ proposed by Yanuka et al. responded most sensitively to the KCl solute concentrations. The empirical constants of a, b, and $EC_s$ for $EC_w$ were -0.249, 1.358, and 0.054 for A horizon, -2.518, 2.708, and 0.097 for Bl horizon, and 2.490, -0.250, and 0.103 for B2 horizon, respectively. Therefore, the results of this study showed that Yanuka et al. equation was most useful one in determining $EC_a$, from TDR signal for agricultural soil with low salinity and that the empirical constants for the calculation of $EC_w$, from $EC_a$ can be obtained through a simple calibration experiment.

Close collaboration among businesses is required in B2B EC environment. Furthermore, emergency requests or critical information among businesses should be processed in an immediate mode. Most current systems, however, due to firewalls for the systems' security and autonomy, can not handle these requirements appropriately, but handle them in an ad hoc manner In this paper a method of timely collaboration among businesses and an active functionality component to support it in B2B EC environment are proposed. Since the active functionality component supports high level ECA rule patterns and event-based immediate processing, system administrators and programmers can easily program and maintain the timely collaboration independently to the application logic. The proposed active functionality component uses HTTP protocol to be applied through firewalls and is designed using a commercial DBMS for practical purpose.

Emergent requests or urgent information among enterprises require their intimate collaboration in B2B EC (electronic commerce). This paper analyzes the needs of intimate cooperation of distributed EC systems in terms of business contracts and presents an active rule-based methodology of close cooperation among EC systems and an active rule component to support it. Since the rule component provides high level rule patterns and event-based immediate processing, system administrators and programmers can easily program and maintain intimate cooperation of distributed EC systems independently to the application logic. The proposed active rule component facilitates HTTP protocol. Its prototype is implemented in B2B EC environment and evaluated using basic trigger facility of a commercial DBMS.

The use of the internet to facilitate commerce among companies promises vast benefits. Lots of e-marketplaces are building for several industries such as chemistry, airplane, and automobile industries. This study proposed new B2B EC business model for the shipping industry which concerns relatively massive fixed assets to be fully utilized. To be successful the proposed model gives participants to support useful information. To do this the expert system is constructed as the hybrid prediction system of neural network (NN) and memory based reasoning (MBR) with self-organizing map (SOM) and knowledge augmentaton technique using qualitative reasoning (QR). The expert system supports participants useful information coping with dynamic market environment. with this transportation companies are induced to participate in the proposed e-marketplace and helped for exchanges easily. Also participants would utilize their assets fully through B2B exchanges.
