Global e-Trade system which electronically processes all trade transactions of trading companies is an essential platform where export and import firms enhance international competitiveness. This study is to develop research models suitable for e-Trade and empirically analyze them in order to examine and verify factors affecting e-Trade system of trading companies on the basis of previously-verified studies on global e-Trade such as TAM, TOE, and Task-Technology Fit Model(TTF). Among many factors, this paper comprehensively analyzes an acceptance factor, which is one of the factors affecting the implementation and performance of e-Trade, from the technological, organizational, and environmental context. The finding from this paper will be applied to e-Trade projects carried out by the government in the future by analyzing the correlation between acceptance and performance.

E-learning has the potentials to provide educational publicity and equality, and has been deployed rapidly in many areas of our society. Growth of e-learning market is also rapid and sustained. However, for e-learning to be a good solution, enough contents should be provided, for which sharing limited contents in the early deployment stage should be necessary. In this paper, we survey some activities about contents sharing. On the other hand, there have been many complaint from e-learning about its effectiveness. Therefore, in this paper, based on the poll results on concentration and satisfaction of e-learning, we also study practical ways to improve studying efficiency of e-learners.

Since MegaStudy started e-learning business for Korean high school students, the Korean e-learning industry began to expand and steadily gain attention. This paper focused on the analysis of the development of the Korean e-learning business for teens and the growth of MegaStudy. The three institutional mechanisms were used to examine the factors that aided the development of the business. The regulatory mechanism was the government policy to prevent the expansion of the offline private education sector, which greatly aided the growth of the e-learning business. The mimetic mechanism was the notion to mimic the characteristics of the Korean e-business initiatives. The normative mechanism involved the widespread social norm suggesting that every student should be given an equal opportunity of private education. This paper also examined the case of MegaStudy as a successful case of the e-learning companies. It analyzed the business model of MegaStudy, which is based on its advantage as the front-runner and its high-quality contents and services.

The International Chamber of Commerce (ICC) eUCP came into force on 1 April 2002. The eUCP is a supplement to the current existing Uniform Customs and Practice for Documentary Credits (UCP500), which governs the use of electronic presentation. The eUCP is not a revision of the UCP. It is a supplement intended to deal with situations where presentations are made electronically. That is to say, the eUCP is a supplement to the UCP that, when used in conjunction with the UCP, will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. The purpose of this paper is to study on the criterion of examination of electronic records under the eUCP.

This paper proposes a public oriented e-Marketplace that induces strategic coalition using database in which detail information about each firm is contained. A public oriented e-Marketplace links each firm through the type of Internet business model and constructs a trading community. We introduce a design methodology of public oriented e-Marketplace called as social network analysis. Social network analysis helps each firm's network easily visualized and completely modeled. Additionally, this paper tries to analyze the relationship among the level of competition, potential of strategic coalition, and financial performance. We demonstrate the firm to easily accept various strategic coalitions can make higher financial performance under the more competitive condition. This implies that strategic coalition through public oriented e-Marketplace provide the each firm with various opportunities.

This paper is a case study on determinants of e-SCM performances. It suggested effective factors related with e-SCM performances for common feature, and point of difference between case firms. So the paper investigated former literature. Then it derived determinants on e-SCM performances. The authors found that establishment of e-SCM project team, mind change of top management, sharing of information, establishment of exact demand and supply plan, the best use of information technology, scale of organization, and collaboration of between firms are key success factors of e-SCM. Case company were three companies. The paper chose SONY, and Samsung Electronics among electronic companies, and HAITAI among confectionary companies. It analyze three companies about common feature, and point of difference, regarding seven effective factors as mentioned above.

e-Commerce in Small and Medium-sized Enterprises(SMEs) provides a platform for fair competition between SMEs and large enterprises, and brings economic benefits to SMEs. Thus in the recent years, the e-Commerce in SMEs developed rapidly. However, the overall proportion of e-Commerce in SMEs in China remains low, and many SMEs' decision-makers tend to feel that their business is relatively weak in terms of information construction of scale and financial management, thus they keep the 'wait and see' attitude about the e-Commerce development decisions. Therefore, SMEs are facing three puzzles about e-Commerce application. First, if the companies need to implement e-Commerce, what are the e-Commerce adoption decision factors. Second, what are the successful implementation factors of e-Commerce. And how about the relationship between them. The third is how to measure the implementation effect of e-Commerce. What is the performance evaluation factors of e-Commerce. In this paper, the theoretical and empirical exploration and research are conducted towards these SMEs. Considering the actual situation of SMEs, this paper builds a theoretical model, then puts forward relevant hypothesis. This paper analyzes present influencing factors based on enormous research papers, and finally discovers the critical successful factors in doing business with e-Commerce in SMEs by conducting Structural Equation Modeling. Five critical factors are verified by cases of enterprise by demonstration study. Lastly, we can draw a conclusion that the innovation ability of leaders, the IT support of leaders and e-Commerce strategies are the success factors of e-Commerce for Chinese SMEs.
