Among EC areas. the B2B EC market is being spotlighted as an important interesting research area considering its size and the potential impact on companeies and the whole society. In comparison with private consumers in B2C EC. business buyers in B2B EC have to precisely keep track of the purchase records. and integrate them with the buyer's e-procurement system, which might have been implemented as a part of integrated ERP (Enterprise Resource Planning) systems. There are three approaches for such integration between ERP and e-marketplace in B2B EC; Two previous approaches are Inside-Out approach and Outside-In approach. And a newly, one is b-cart approach. In this paper, we try to survey these three approaches and make a comparison analysis. From this research. we identify that the b-cart approach is the most efficient framework in integrating ERP with e-marketplace in B2B EC.

In the beginning of new millennium, Business-to-Business(B2B) Electronic Commerce(EC) is a hot issues of the world business and economic communities. The market of B2B EC is increasing rapidly, and become a more complex and competitive because many participants and intermediaries are play on their own objectives and strategies. To cope with the situation, participants of B2B EC market should make play with a competitive strategies. So, the participant enterprises must know the critical success factors of their own EC market. This study identifies B2B EC success factor measurement sets, and explores several success factors based on the perceived importance of B2B EC practitioner in the manufacturing enterprises. The study tests the differences of success factors by IS level, EC business model characteristics, and EC introduction and operating characteristics.

EC-2B와 EC-2C 획분은 정향(Eugenia caryophyllata)의 알칼리 추출물로부터 에탄올 침전, cetavlon 처리 및 한외여과를 거쳐 분획하였다. EC-2B 획분은 APTT에서 항응고 활성을 가지는 반면, EC-2C 획분은 APTT와 TT 모두에서 항응고 활성을 가지고 있으며 EC-2B와 EC-2C에서 모두 혈소판 응집억제능을 관찰할 수 있었다. EC-2B와 EC-2C 획분의 경구투여에서 두 획분 모두 독성이 없었으며 EC-2B 획문은 1,000 mg/kg (mouse, intravenours)에서도 독성이 없었으나, EC-2C 획분은 LD50 322 mg/kg 정도의 독성을 가지고 있었다. 두 획분의 in vivo 성에서의 항응고 활성을 60% 생존율을 갖는 dose로 표시한 결과 EC-2B는 131 mg/kgdlsep 비해 EC-2C는 58 mg/kg로 활성의 차이가 in vitro에서 보다 크게 나타났다. 이 두획분을 sulfation시킨 후 활성의 변화를 ex vivo를 통해 확인한 결과 두 획분 모두 활성이 증가하였으며 특히 EC-2B 획분의 활성이 급격히 증가하였다.

B2B EC는 그 시장규모와 기업, 사회전반에 미치는 영향이 커다란 주요한 연구 분야이다. 그런데, B2C EC와 달리 B2B EC에서는, 구매자의 전자시장에서의 구매기록은 ERP로 대표되는 기업내의 전자구매시스템과 통합되어야 한다. 이를 위한 구조로서 기존의 Inside-Out 접근방식과 Outside-In 접근방식, 그리고, 최근의 b-Cart 접근방식이 있다. 본 논문에서는 이들 3가지 방식에 대한 고찰과 비교 분석을 시도한다. 이를 통해서 기업간 전자상거래에 있어서 ERP와 전자시장과의 통합구조로 b-Cart 접근방식이 효율적인 프레임웍임을 확인한다.

Since B2C EC websites not only become a valuable channel for selling goods to customers and for communicating with the potential clients, but also offer companies an important vehicle for attaining competitive advantages in the new digital economy, the design and content of website must reflect its business goals and customers' needs. However, as little empirical evidence on the effect of B2C EC website contribution of firm performance exist, the functionality of B2C EC website has been decided voluntarily from its business experience. Hence, there has been a call for a rigorous empirical studies to examine the function level of an B2C EC website application. The purpose of this study is to examine the relationship between the function level of B2C EC website and its performance considering the characteristics of B2C EC strategy as moderating variable. 125 questionnaires from internet shopping malls which sell physical goods direct to an individual end consumer were collected. The results showed that four factors(price, product recognition, reliability enhancement, and purchase confidence) affect positive effects on the performance of shopping mall, and the characteristics of B2C EC strategy can be considered as a significant moderating variable between price factor and the performance of shopping mall.

Even though B2B EC is becoming popular, there have been not so much studies about performance evaluation methodology for B2B systems. In this paper, after analyzing buyer-carts systematically focusing on the buyer's interactional efforts on the typical buying processes of each buyer-cart, we propose a quantitative performance evaluation model. For this, we categorize buyer-carts in B2B EC as s-cart, i-cart, and b-cart depending upon its residing sites: seller, intermediary, and buyer sites. And after proposing the desired features of buyer-carts in B2B EC as identification, collection, trashing, ordering, payment, tracking, recording, purchasing decision support, and transmission of records to e-procurement systems, we derive a performance evaluation model by calculating detail sub-processes from the desired features' viewpoints. By setting variables from a survey on the actual condition of using buyer-carts in companies in Korea, we try to evaluate the performance of buyer-carts in B2B EC. In this paper, we suggest a new methodology of performance evaluation for B2B systems, and show that the b-cart platform is more efficient than other buyer-carts especially in B2B EC.

B2B EC에서 지능형 에이전트에 대한 요구의 증가와 함께 기업구매자가 직접 전자시장으로부터 구매하는 데스크탑 구매의 요구도 증가하고 있는 추세이다. 본 논문에서는 B2B 상에서 전자시장으로부터의 효율적인 구매를 지원하는 b-Cart 기반 에이전트 시스템의 설계 사례에 대해서 기술한다. b-Cart는 구매자가 소유하고 사용되는 구매자 사이트에 위치한 쇼핑카트로서, 본 논문에서는 B2B EC에서의 b-Cart 기반 에이전트 시스템의 요구 기능을 사용자식별(Identification), 사용자 다이알로그(User Dialog), 상품정보수집(Collection), 물품정보제거(Trashing), 개별 구매의사결정지원(Individual Purchase Decision Support), 조직 구매의사결정지원(Organizational Purchase Decision Support), 협상(Negotiation), 주문처리(Ordering), 지불처리(Payment), 진행사항 추적(Tracking), 구매기록(Recording), 전자구매시스템에 구매기록 전송(Record Transmission), 지식베이스에 새로운 지식 유지(Knowledge Maintenance)으로 정의하고, b-Cart 기반 에이전트 시스템의 메시지 인터페이스를 설계하고 시스템의 구조를 설계하여 프로토타입 시스템인 AgentB의 설계 사례를 소개한다. b-Cart 기반 에이전트시스템은 기업구매자의 전자시장으로부터 구매자 증가함에 따라 분산된 정보를 관리 해주고 통합적으로 구매처리를 해줄수 있는 효과적인 시스템이다. 향 후 B2B EC의 에이전트 시스템은 b-Cart를 기반으로 할 것으로 예측할 수 있다.

Buyer-carts to support the purchasing process in the B2B EC platform, can be categorized as s-cart, i-cart, and b-cart depending upon its residing sites : seller, intermediary, and buyer sites. In this paper, after proposing the desired features of buyer-carts in B2B EC as identification, collection, trashing, ordering, payment, tracking, recording, purchasing decision support, and transmission of records to e-procurement systems, we try to analyze each buyer-cart qualitatively from such viewpoints. Moreover, we propose an efficiency evaluation model for quantitative analysis. By setting variables from interview of employees in 30 listed companies In Korea, we try to evaluate the efficiency of buyer-carts in B2B EC. From this paper, we show that the b-cart platform is more efficient than other buyer-carts especially in B2B EC.

Emerging digital economy, e-business, especially business to business(B2B) electronic commerce is understood one most single critical competitive weapon for organizations' global competitiveness. According to government white paper, Korea's electronic commerce records expansion stage in its volume and variety. Although Korea has remarkable EC records, still some differences are existed compare to the developed countries. IT in the developed countries, played an engine for the economic restructuring as well as for the economic growth. But in Korea, it's not fully utilized by the reasons of economic and noneconomic bottlenecks. Under the digital economic surroundings, EC or e-Business, is a business system to achieve the economic efficiency in the levels of an organization as well as a nation. So, we have to find the ways to utilize our EC infrastructure to contribute for the nation's global competitiveness. To find the way, this study recommends two types of policies, pull and push, beyond the OECD's suggestion, to government in order to expansion of EC, especially B2B EC.
