Electronic Commerce (EC) has been at the center of discussion as a symbol of the integration of unprecedentedly developed Information and Communication Technologies (ICTs) and traditional commerce. In spite of much attention to EC, the research from a spatial perspective has not proliferated yet. EC was regarded to have aspatial characteristics based on the expectation for a global expansion of business activities in a digital economy. This paper attempts to figure out the spatial characteristics of public Business-to-Business electronic marketplaces (public B2B e-MPs), as one of the most evolving forms of B2B EC, regardless of the low proportion in B2B EC at present. Many of the firms operating public B2B e-MPs in Korea were located in Seoul, especially in Gangnam-gu. The analysis of three spatial indices showed their extreme spatial concentration. The analysis on the location factors of Public B2B e-MP firms in Korea demonstrated that location factors of public B2B e-MP firms were differentiated by regional groups: Gangnam-gu, Seoul except Gangnam-gu, and the provinces. It was againt an initial extreme expectation that the firms relevant to B2B EC will not care about physical locations because they mainly do businesses in electronic space. The differences between those in Gangnam-gu and in the provinces were strikingly prominent. Such differentiated location factors by region were closely related to the different attributes of the public B2B e-MPs by region. In conclusion, public B2B e-MPs are not irrelevant to physical space and physical proximity, at least at a current stage. Customized spatial strategies are required for successful online businesses.

With the proliferation of electronic commerce (EC), the product items which are transacted and the user classes who utilize the EC are spread rapidly. Many users have to expend time and effort in searching of products an or the shopping malls which deal with the products. For his reason, the intelligent retrieval of both malls and products based on an intelligent software agent has been raised as a hot issue. In this paper we have constructed an ontology server that is an essential constituent for agent-based intelligent EC. And also we have designed and implemented a use adapted personalized product search function based on the ontology that are registered in the server.

최근 통신 기술과 컴퓨터 기술의 괄목할 만한 발전으로 가장 않은 연구의 초점이 되고 있는 것은 인터넷을 이용하여 거래하는 전자거래이다 따라서 실세계의 상거래를 사이버 스페이스에서 구현할 수 있도록 하는 한 가지의 기술로서 인공지능을 이용하여 모델링하는 방법이다. 본 논문에서는 전자거래(EC) 컴퍼넌트형 지식 기반의 지능 에이전트 유형을 제시하고, 특히 기존의 전문가 시스템의 추론 엔진에 다층의 지식 기반과 정보처리 엔진을 이용하여 에이전트 상호간에 효율적이고 유기적인 활용 방안을 제안한다. 또한 컹색 에이전트에 필요한, 고객 만족을 위한 상품 검색의 이론적 모델을 설계한다.

There are many web-based applications which need graphs and charts to be generated from data stored in the database. This paper does a comparative study on graph processing techniques for web-based applications through a case study of building a stock information system. The result of this paper can be used for building effective web applications with graphs in areas of EC(electronic commerce), EIS(executive information system), and DM(data mining).

As the world-wide use of the Internet increases rapidly due to development of computer network the Electronic Commerce for business by treating it is growing as compared to the traditional one for the information exchange in the academic and research areas. The Electronic Payment System used for EC includes the Payment Broker System and the Electronic Purse System. And usually Electronic Purse System operates with IC cards. Saving the money in IC card has a high portability and security. Therefore, the Electronic purse System based on IC card is recently issued in the EC. In this paper, we design and implement of a IC card security system for Common Electronic Purse Specifications in Internet. CEPS is a Electronic Purse System proposed VISA, and conform EMV(Europay Mastercard VISA) security structure. With our system, users easily use Electronic Purse System with only Web browser and IC card. Original EMV paid no regard to using in the Internet. But our system, conforming to CEPS and EMV, is easily used in the Internet.

Traditional intermediaries refer to service providers such as travel agents, real estate brokers, job agencies and insurance agents which matching services for buyers and suppliers in a traditional market. The introduction of Electronic commerce resulted in the automation of many tasks provided by intermediaries and seemed to eliminate the role of many traditional intermediaries, which is called disintermediation. However, depending on their market power, traditional intermediaries either will be disintermediated or fill new roles by providing added value and assistance, which is called reintermediation. According to the research of Alina M. Chircu et al. there are three conditions for reintermediation for traditional intermediaries. Three conditions are weak appropriability of EC innovations, ownership of co-specialized assets for both market intermediation and EC innovations and economies of scale. Besides these three reintermediation conditions, we hypothesize that leveraging BPO can be a suitable strategy for traditional intermediaries to be transformed into reintermediaries. Business Process Outsourcing (BPO) is the leveraging of technology or specialist process vendors to provide and manage an organization's critical and/or non-critical enterprise processes and applications. This paper will investigate the relationship between above reintermediation conditions including BPO and reintermediation.

Nowadays Electronic Commerce shopping mall is welcomed more and more on the Internet. It is expected that Shopping mall systems come to be various and adaptable to complex requirements according to customers who have these various needs, but just show products list, instead. This thesis suggests various structures of shopping malls showing interface agent model using Case-Based Reasoning one of reasoning method of Artificial Intelligence instead of the method of prior EC shopping mall. 1 constructed case base by making index with shopping mall members and customers' private informations, and pursued difference from prior EC shopping malls by proposing to customers cases of other users' selection of products who have similar private informations with them.

현재 전자상거래는 관련기술의 발달로 인해 세계적으로 빠르게 확산되고 그 규모 또한 커지고 있는데 전자상거래는 단순히 구매행위만을 의미하는 것이 아니고 상거래와 관련된 문서교환, 교섭 등의 일련의 모든 행위를 포함하는 개념으로 최근 이 전자상거래를 CALS와 연관하여 CALS/EC라고 부르기도 한다. 우리군에서도 국방조달본부 등에서 CALS/EC 체계의 구축을 위한 사업이 추진되고 있는데, 이러한 체계가 이루어진다하더라도 많은 문서량과 관련업체로 인해 사용자가 업무를 수행하는데 많은 어려움이 있을 것이다. 따라서, 전자상거래의 여러 기술요소들에 부가하여, 최근 크게 주목을 받고 있는 에이전트기술을 이용해 사용자의 비전문성을 극복하고 편리성을 제공해줄 수 있도록 국방조달업무중 공고, 입찰, 계, 구매, 지불 업무를 위한 국방 군수 조달 전자상거래용 지능형 멀티에이전트 시스템 설계에 대해 연구하였다.

The Internet has become a part of our life and has changed our living environments dramatically. However, Electronic Commerce (EC) stays currently at a level that a buyer deals only with an one-sided condition (price) proposed by a seller or compares the proposed condition to find a better one. As the agent technology makes progress, EC requires negotiation that is not one-sided but is a way to maximize profits of both seller and buyer. Moreover, negotiation in EC should consider multiple issues rather than a single issue to replace the traditional commerce. In this paper we propose a negotiation model, which guarantees balanced profits between two agents through negotiation using multi-issues, and makes a deal successfully under time-constraint environment. The proposed negotiation model suggests strategies(alternative and simultaneous strategy) that change the value of issues with each agent has time for negotiation. In this paper, we also suggest a strategy that proposes an offer to each other. We compare the proposed negotiation model with another negotiation model. The experimental results show that dynamic conceder tactic and linear tactic showed balanced profits and a high percentage of deals for negotiation between two agents, and the sum of utilities of two agents is high, when the alternative strategy is used.
