Recently, many researchers have tried to establish EC framework EC framework for automated contract and brokerage using agent technologies in electronic commerce. Traditional researches, however, often enforced the user's participations during the automated brokerage process of agents an did not supported the procedures and methodologies for satisfying various user's requirements. In this paper, we propose a brokerge framework based on multi-agent to overcome the defects of the previous researches. For the optimal brokerage, the proposed framework is divided into tow layers, which are called competition layer and constraint satisfaction layer. The Agents process behaviors of brokerage through two layers accroding to th proposed message driven communication protocol. W also apply CSP (Constraint Satisfaction Problems) techniques to brokerage process to satisfy various preferential requirements from the user. That is, e model the relationship between buyer agents and seller agents using CSP and propose efficient CSP models for the optimal brokerage as the types of brokerage. Finally, e implemented prototype systems applying the proposed framework and showed the efficiency of he proposed framwork with the experimental results.

A legal system is designed to regulate social phenomena appropriately minimizing potential disputes arising out of conflicts with social phenomena and to seek for stability of legal life. The development of information technology and network infrastructure changed way of communication significantly, which realized the new transactional concepts, such as EDI(Electronic Data Interchange), Commerce At Light Speed(CALS) and Electronic Commerce(EC). However, current legal systems of each nation, which are based upon the paper document, do not seem to accomodate such types of emerging transactions. In that context, we can observe many issues which cannot be resolved among the parties involved in such transactions even under the several sui-generis statutes regarding EDI in Korea. Based upon the recognition of the above circumstances, this paper will browse legislative efforts in advanced countries and international institutions like UNCITRAL, and WTO. Also this will cover outstanding issues in relation with the deployment of electronic commerce in Korea and suggest what should be revisited for better accommodation of the changes going on.

Electronic commerce, driven by the development of the Internet and computer, premises to be an important engine for growth for the world economy in th the 21st century. Electronic commerce offers considerable new opportunities for the business and citizens in all regions of the world by enhancing productivity across of our economics and encourage trade in both goods and services. Specially in relation to contract, electronic commerce requires a coherent, coordinated approach internationally on key issues such as a validity, a legality, consumer protection. Electronic commerce, which breaks down national boundaries and widens the gap between the place where services are performed and the place where they are consumed, requires a new paradigm when making an between contracting parties.

As EC replaces traditional market methods in many places, the market size of EC is greatly expanding year by year according to some researchers. Even though several researchers have proposed several success factors for the success of EC, there are many differences among these factors. The main purpose of this research is to improve the original research works of Lederer et al.(2001) which might have some more modification works. This study modified and added several success factors based on the original research works of Lederer et al.(2001). This modified research works have been tested by using SPSS and Lisrel statical packages. The results of this study shows some improvements against the of original works of Lederer et al.(1991).

As a rapid development of electronic commerce transactions in these days, the security and private protection problems became more important matters under the electronic transaction base. Because electronic transaction using electronic documents be carried without direct person to person meeting, there can be the possibility to use other's identity illegally without notice, and very hard to verify authenticity of transaction as well. In addition, it is very hard to find out that the electronic documents on the process of submitting is forged documents or not, and also have much difficulty in maintaining transmitting secret. Therefore, to solve such problems on electronic commerce transactions and electronic documents, the digital signature and certification system with cryptography skill is inevitably necessary. As the wide use of digital signature together with beginning of digital government and financial transaction, not only the issuance of electronic certification, but certification market came to gradually expand. In Korea, after enacting digital signature act in 1999, the act contents were expanded to the wide range of contents complying with global standards from the end of 2001 to April, 2002, including the new clause of certification problems. And the act was put into operation now. Therefore, in this paper, we'd like to suggest development scheme through the investigation on electronic certification related problems, such as, concepts, procedures, service conditions here and abroad.

The study on the critical success factors (CSF) for electronic commerce systems has been a hot topic in both academe and industry. On the basis of reviewing papers on CSF and analyzing their problems, this paper designs the initial assessment indictors and website features and functions influencing EC success. Using Delphi survey and data analysis, we get the five important assessment indictors and seven important web features and functions. Furthermore, the hypothesis of CSF model is proposed. Finally, we conduct a survey on the Chinese Publishing Industry to test the hypothesis. The result shows that the hypothesis is partly supported, which means useful and understandable information, complete and timely information, credible and accurate information, all product-related information are the critical success factors for EC publishing industry. This research not only impels EC research in China, but also has instructional effect on the implementation of EC for enterprises to increase the success rate of EC.

Nowadays, most companies seek after the greatest profit by means of offering the goods which consumers want timely and efficiently and minimizing the cost of inventory and distribution channel which amounts to the great portion of total cost. And according as EC(Electronic Commerce) market has increased rapidly, SCM(Supply Chain Management) for EC become one of the most important facts for companies, therefore this paper suggest SCM scheme which EC, especially B to C, is added to the existing commerce system. This paper uses internet for information integration of distribution channel which is away from one another and applies TOC(Theory of Constraint)'s DBR(Drum-Buffer-Rope) Scheduling for synchronization through the whole supply chain. It is possible to synchronize the whole supply chain by means of making the speed of manufacturing and distribution to be controlled by consumer's order which is received in distribution center, and inventory and loss of sales opportunities are minimized by constant. Buffer Management. If inventories in distribution center is short, then it needs to search CCR(Capacity Constraint Resource) in supply chain and to control the speed of manufacturing and distribution according to the ability of CCR. This paper applies PT(Partial Transshipment) strategy for Delivery from distribution center to store or cyber consumer. the strategy this paper suggests chooses neighbour area from area which each distribution center takes charge, and then makes product ordered by cyber consumer which lives in the chosen area to be delivered according to inventory of distribution center.

CALS(Commerce At Light Speed)/EC(Electronic Commerce) is drawing considerable interest as strategic part of efforts for computerization of the government and companies and for industry-wide innovation, using Internet and information superhighway that is widely expanding world-wide with the development of computers and information communication technology. In the current industry infrastructure, standardization is difficult but very important among the parties that want to share the added value, as external environmental components increase since the advent of computers. However, information security technology is not permitted to be exported in light of national interest or high amount of royalty should be paid. Moreover, if we cannot fully analyze the international standard and imported technology in order to verify the safety of using them, domestic information can be exposed according to the desire of the country exporting the technology. In particular, information security technology should be developed by ourselves, considering technology Protection and export Prevention Policies of foreign countries. Therefore, this paper presents information security technology and standardization trends for several application fields regarding CALS/EC implementation in our and foreign countries. This paper also analyzes such trends and proposes strategic direction for standardization suited for domestic environment.

Electronic Commerce (EC) is a relatively new and has been attracting a considerable amount of attention. Even though it is still in an introductory stage, growth rates are impressively high and its economic importance will continue to grow. Electronic Commerce is born to be global because its connectivity using the Internet is universal. As Electronic Commerce accelerates the globalization, it will also increase both the interdependence of national economies in different countries and the need for international cooperation and coordination. Electronic Commerce is really a global challenge that requires global solutions. For this reason, Electronic Commerce becomes an important agenda in major international cooperative organizations including APEC, OECD, and G7 (G8). However, current international discussions on Global Electronic Commerce are initiated mostly by the United States and European Union (EU). The objective of this paper is to raise awareness creation activities in which the international cooperation is needed for promoting the global electronic marketplace in Asia. For this purpose, this paper reviews the approaches of U.S. and European countries (or European Union), and suggests an development framework on the basis of the reviews. The framework is used to analyze current issues around Electronic Commerce, and identify some fields which require coherent work among researchers in different countries.
