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.

법제도는 사회현상을 적절히 규제함을 그 목적으로 하고 있고, 그 규율의 대상인 사회현상에 있어서의 분쟁가능성을 최소화하고 아울러 법적 생활의 안정성을 도모하여야 하는 것이다. 또한 예측 가능한 범위내에서 닥쳐 온 미래의 사회현상에 대하여도 대비하여야 하는 것이다. 통신인프라의 발달은 의사나 정보의 교환방식에 대한 획기적인 변화를 가능하게 하였고, 이른바 전자적 방식에 의한 정보, 문서의 교환이라 할 수 있는 전자문서교환(Electronic Data Interchange), CALS(Commerce At Light Speed) 또는 전자상거래(Electronic Commerce)라는 개념이 등장하기에 이르렀다. 그러나 기본적으로 종이문서에 기반을 두고 마련된 기존 각국의 법제도는 이러한 새로운 형식의 거래를 규율함에 있어 적합치 않은 점이 많이 있을 뿐 아니라, 현재 우리나라의 해당분야의 전자문서교환을 개별적으로 규율하는 특별법에 의하더라도 해결되지 아니하는 많은 문제점을 발견할 수 있다. 이하에서는 인터넷 환경하에서의 전자상거래와 관련한 각국에서의 활용현황 및 제도적 준비를 검토한 위 우리나라의 현행법 체계의 문제점을 점검함과 아울러 입법의 기본원칙과 입법 항목을 점검해 보고자 한다.

전자상거래의 과정은 종래의 거래방식으로는 생각지 못했던 방식으로 계약이 체결되고 결제가 이루어지며, 상품이나 서비스가 이동되고 무역거래에 수반되는 각종절차를 수행하게 된다. 따라서 과거의 법이론 및 사회제도 안에서 예측하지 못했던 많은 문제점들이 표출되었고 이러한 추세에 따라 미국에서는 자국내의 법 제도적인 환경을 전자상거래에 적합하도록 하기 위해 통일상법전(Uniform Commercial Code ; UCC)의 개정을 단행하였다. 특히 대개정에서는 제2장 물품매매계약 분야를 대폭적으로 개정하여 컴퓨터나 정보통신기술을 통한 전자식 매매계약의 성립요건을 규정하고 있다. 이러한 개정안은 전자적으로 계약을 체결하고자 하는 요구의 증가로 우리에게도 상당한 영향을 미칠것으로 예상된다. 따라서 본 연구에서는 UCC의 Cyber 매매계약법의 내용을 우선고찰하고 컴퓨터 On-Line을 통한 매매계약관계의 성립범죄와 계약의 전제조건을 서면에 의한 일방계약법이론과 구체적 비교분석하여 국제매매계약의 성립이론을 정립하는데 일조하고자 한다.

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.

전자상거래는 비교적 짧은 연륜에도 불구하고 경영, 경제 전반에 걸쳐 상당한 주목을 받고 있다. 비록 아직은 시작단계이기는 하지만 그 규모가 급성장하고 있으며 경제적인 중요성도 날로 더해갈 것으로 전망된다. 한편 인터넷을 기반으로 발전하게 된 전자상거래의 가장 큰 특징은 범세계화 (Globalization)라 할 수 있다. 전자상거래의 확산은 이러한 세계화 추세를 더욱 가속시키고 있으며 여러 국가의 경제가 하나의 시장으로 통합되어 갈 것으로 예측된다. 따라서 이러한 새로운 경제 패러다임에 적절히 대응하기 위해서 국제적인 협력과 공동 노력이 필요하게 되었다. 이러한 이유로 전자상거래는 APEC, OECD, G7 등 주요 국제기구의 주요 의제가 되고 있다. 현재 전자상거래와 관련된 국제협력은 미국과 서유럽국가 (유럽연합:EU) 들이 주도하고 있으며 주요 협력 내용도 전자상거래의 인프라 및 환경조성 등에 초점을 맞추고 있다. 본 논문의 목적은 아시아 국가들 간의 전자상거래 활성화를 위한 국제적 협력의 필요성을 제기하고 주요협력 안건을 찾는 것이다. 이 목적을 위해 전자상거래와 관련하여 미국과 유럽연합의 접근방법을 재검토하고 전자상거래 활성화를 위한 주요 현안을 제시하였다. 이를 위한 전자상거래 발전 모형을 제시하였으며 이를 통해 국제협력이 필요한 영역을 살펴보았다.
