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.

Today, information society is affected by new technologies including Electronic Commerce(EC), Electronic Data Interchange(EDI), Commerce At Light Speed(CALS ), multimedia and teleconferencing. Electronic Commerce is believed to be a field that will bring about a huge revolution of human life in the 21st century and thus its industry will give greatly influential effect on other industries In this paper, we have surveyed and studied through the internet and related materials for the development of framework of Electronic Commerce. It is required that we need the leading role of our government for the earlier activation of Electronic Commerce usage and have to establish the solid background of EC technology creation of our nation's originality and to activate the venture industry oriented for idea and technology rather than the industries in the form of larger enterprises. In conclusion, we have to expand our own ability of research and development to keep the continuous growth of our Electronic Commerce market and industries through the development of new product and prior acquisition of market as well as to expand the path of various technology aquisition by the strategic M&A and capital investment with the leading foreign enterprises.

Inspired by the growth of the Internet, electronic commerce(EC) has grown rapidly over the last few years and has become a major Internet application domain. EC encompasses various profit-oriented activities such as purchase of goods and services over the network, banking, and business-to-business trade. The purpose of this research is to develop an electronic commerce merchant server for the small and medium size business. The proposed solution is designed to meet a cheap, simple, extensible, and interoperable requirement. Also, our solution supports one-to-one marketing concept by using matching technology. We expect that our solution makes the small and medium size EC market more easily.

Intercompany online businesses can offer digital information to each company, and yet without legal verification business activities are less efficient. Just one single country cannot control this problem with its own EC law and now international cooperations are being required. Currently, International Regularization is the main agenda among the international organizations such as UNCITRAL, OECD and WTO and so on. Furthermore, most of the advanced nations, including the USA and EU, announce their fundamental strategies for the multilateral regularization in their favor. At the present stage, South Korea's Electronic Commerce law and Digital Signature law went into effect as from July 1, 1999, indicating that they can strike the keynote of the systematic infrastructure for the electronic commerce transactions in this country.

Nowadays, the explosive evolvement of Internet. which is referred to as EC, has been prevailing. That has given the chance all of the world consumers to contact all of the world companies to enter into business relationship. But, electronic commerce laws have been established per conventional jurisdiction. some legal issues take place in the field of cross-border electronic commerce, including the governing law and competent courts. In this situations, it is gradually and widely required to lay down the internationally harmonized electronic commerce legal framework. Now, there are a lot of legal issues assumed in EC, in this study, we studied three precedence problems concerning B2C: Consumer Protection Law regarding B2C, Personal Information Protection Law in Private Sector regarding B2C, Web Site Trust Mark System.

This paper attempts to identify variables which affect Korean electronic commerce(EC) venture's strategies for the international market entry decision making. Especially in the perspective of quality management perspective, it is highly relevant question which factors are critical when the industry has high technology driven characteristics such as EC, product quality related factors or environmental factors. Technology competence, operational competence, local marketing competence, psychological barriers, domestic competition level, and local infrastructure level are included to generate the explaining model for international market entry decision. The result is that the higher technology competence and local marketing competence are the significant factors. The higher the perception in these factors, the higher the intention to enter the international market in EC industry. These factors play a pivotal role in determining to go abroad the foreign EC market. Our finding implies that the subjective confidence on quality of EC solution(technology competence) and venture's capability of maintaining it(local marketing competence) are the important factors, when EC ventures make the decisions to enter the foreign markets.

This Study intends to find the impact of industry type on the relationship between Electronic Commerce(EC) implementation and performance. For this purpose, empirical study of domestic small and medium enterprises(SMEs) is carried out to test the relationship between EC implementation and EC performance and the moderating effect of industry type on the relationship between them. Previous empirical studies on EC mostly focused on the adoption of EC by business firms, and also have been carried out with the data from big enterprises. More often than not, the results obtained from the large business firms are used to provide the guidelines for SMEs. SMEs are, however, different from large business firms in many aspects, and need to be studied on their own. Empirical test shows that there are differences between manufacturing industry and service industry in utilizing EC and in achieving EC performance. The results of data analysis indicate that the industry type of SMEs is moderating the relationship between EC implementation variables(EC type, EC strategy, EC formality and EC character) and EC performance variables(EC utilization, EC satisfaction and EC usefulness).

The objective of this paper is to propose a brand new interface mechanism to provide more intelligent decision making support for EC problems. Its main virtue is based on a numerical process mechanism by using an Extended AND-OR Graph (EAOG)-based logic algebra. Using this mechanism, decision makers engaged in electronic commerce (EC) can effectively deal with complicated decision making problems. In the field of traditional expert systems research, AND-OR Graph approach has been suggested as a useful tool for representing the logic flowchart of the forward and/or backward chaining inference methods. However, the AND-OR Graph approach cannot be effectively used in the EC problems in which real-time problem-solving property should be highly required. In this sense, we propose the EAOG inference mechanism for EC problem-solving in which heurisric knowledge necessary for intelligent EC problem-solving can be represented in a form of matrix. Finally, we have proved the validity of our approach with several propositions and an illustrative EC example

EC(Electronic Commerce) which is done on the virtual space through Internet has strong point like independence from time and space. On the contrary, it also has weak point like security problem because anybody can access easily to the system due to open network attribute of Internet, Therefore, we need the solutions that protect the EC security problem for safe and useful EC activity. One of these solutions is the implementation of strong cipher system. YK2(Young Ku King) cipher system proposed in this paper is good solution for the EC security and it overcome the limit of current block cipher system using 128 bits key length for input, output, encryption key and 32 rounds. Moreover, it is designed for the increase of time complexity by adapting more complex design for key scheduling algorithm regarded as one of important element effected to encryption.
