전자문서 전자영수증 대금결제 서명 및 상호인증 등 전자상거래의 거의 모든 영역에서 사용되고 있는 전자서명의 경우에는 특히, 거래 상대방을 확인할 수 있는 확인 절차와 더불어 안전하고 신뢰성 있는 보안시스템의 구축을 위한 암호화가 필요하게 된다. 따라서 전자서명의 일반적 고찰과 관련하여 각국에서 제정되고 있는 법규는 물론 전자서명에 따른 보안문제를 고찰하고자 한다.

The single phase switched reluctance motor (SRM) has many merits; simple structure and driving circuits, easy operation and speed control, and etc. This paper presents the torque characteristics of disk type single phase SRM by changing the salient pole lengths and pole arcs. The prototype single phase SRM has a three dimensional magnetic flux pattern because of its structure. That is, the radial and axial magnetic flux contributes to torque generation. Thus, 3D analysis is required for computation of its magnetic field. In this paper, 3D FEM is used for analyzing the magnetic flux distribution and magnetic co-energy.

This paper presents magnetic field analysis technology that uses a vector magnetic characteristic. Recently the magnetic material was found to be measurable using the vector quantity technique. Therefore considering the anisotropy of the magnetic material in the vector field analysis is necessary. The magnetic field analysis method, which is considered the anisotropy by combining the finite element method with the E&$S^2$ (Enokizono, Soda, and Shimoji) modeling, is applied to a permanent magnet motor model.

In this research, we developed a Multi-Agent based Negotiation Support System to be able to increase the competitive power of a company in dynamic environment and correspond to various orders of customers by diffusion of electronic commerce. The system uses the agent technology that is being embossed as new paradigm in dynamic environment and flexible system framework. The multi-agent technology is used to solve these problem through cooperation of agent. The system consists of six sub agents: mediator, manufacturability analysis agent, process planning agent, scheduling agent, selection agent, negotiation-strategy building agent. In this paper, the proposed Multi-Agent based Negotiation Support System takes aim at the automation of transaction process from ordering to manufacturing plan through the automation of negotiation that is the most important in order-taking transaction.

Since the Start of WTO in 1995, world trade volume was substantially increased as much as over $250 billion by lifting the trade barriors This effect brought new problem of increasing disputes. Significantly an ever increasing atention is paid to the Question of means and procedures of settling such disputes by arbtration. The problem of arbitration has indeed become most popular with all those who take interest in legal aspects of international cooperation in various spheres. In practice arbitration seems to renovate its function to take over new disputes arising from electronic transaction such as internet trade. Looking at the actual use of arbitration, its merits than litigation should cover new aspect concerning new kind of claims caused by new type of transaction. The efficient procedure for dispute will help every country save loss of profit by the delay of settlment. This thesis aims to facilitate the appearence of more efficient arbitration procedure for dispute settlment system.

The Study investigated economic effects and the conditions in the public Shipping e-marketplace. For efficient operation of the public Shipping e-marketplace, this study analyzed how do the participation and community actualize in the public Shipping e-marketplace actualize. According to the research results of the Shipping Cooperations, For Promoting participation in the public Shipping e-marketplace, the Cyber-intermediary operating public Shipping e-marketplace provides timely shipping information, needs publicity strategy generating more benefits than offline transaction, and gives a conviction of the searching costs and transaction costs decrease. Second For promoting community, the Cyber-intermediary must playa major role in electronic community and drive forward continuous publicity strategy in the public Shipping e-marketplace.

In this paper we propose a fair and secure e-commerce model for P2P network, in which communication entities can buy and sell products by P2P contract. In particular, we focus on a fair transaction protocol that is based on a collaboration with distributed communication entities. This feature makes our model very attractive in P2P networking environment which does not depend on any central trusted authority for managing communication entities.

The utilization of Internet, which started only at the level of advertisement, has been gradually expanding its application areas as the trial commercial transaction becomes successful, the password-coding technology which removes the risks on the cyber transaction develops, the electronic money appears and other various related technologies progress. Following this trend the securities industry has been experiencing changes along with efforts to use it commercially. This study is to analyze the work of cyber securities companies on the basis of the theoretical background through preceding studies and literature and also analyze the common and different reasons for superiority-securing strategy in competition along with problems and their reasons. And also the objective of this study is to offer new superiority-securing strategy in competition and problem-solving strategy.

This article explored the bank's responsibilities in electronic payment system between Korea and U.S.A. In order to complete my research object, I used Article 4A of the U.C.C. and EFTA of 1978 and by Electronic Financial Transaction Act of Korea as a analytic instruments. I also adapted America's various regulations to regulate concerned parties(banks). The system of this article is going to display as fellows; First, I presented recent trend and legal stabilities of electronic payment in this article. Second, I focuses on the allocation of risk of loss caused by ambiguous term in payment orders that do not express the subjective intention of the senders. I also did analyze the solution procession of error occurring in course of send of payment order. Third, In any action which involves a customers's liability for an unauthorized electronic fund transfer, the burden of proof is upon the financial institution to show that the electronic fund transfer was authorized. Forth, Customers have to report the error and unauthorized electronic fund transfer after awaring of it. Then bank will be liable for such a unauthorized electronic fund transfer. But If customer's failure to report, the bank has exemptions. Lastly, In order to prevent or detect the unauthorized electronic fund transfer, bank will agree with custom to establish a commercially reasonable security procedure, while bank has duties to notify in order to decrease the loss resulted from unauthorized payment order in korea law.
