There are recently a lot of inconvenience because every client should be set to the proxy server on the browser in order to control the access by means of the client authentication in the proxy server. The client authentication technology using the transparency cache in this paper will be transparently used for every user in the internet which option of the authentication function is simply set in the cache server. In addition, the administrator will get the benefit since he can control the traffic of each client and strengthen the security. And also, this system is expected to use in the eCRM deeply rotated to the tendency of the client in the field of the e-commerce like shopping mall in the internet since the administrator can monitor the pattern of the client using the internet. This technique can be applied to the company affiliated research center, the EC website, and the military where it is essential for the tight security even though there are no additional security devices.

Security is very important in EC(Electronic Commerce) environment because exchanged information(that is transaction details, private data, charges data(card-no, accounts), etc) is various and is very sensitive. So, In this paper, we propose Secure-ReXpis(Reliable St excellent Xh3 Processing Infrastructure) System that transfer message and support Message Level Security(Encryption/Decryption and Digital Signature). And we implement Message Confidentiality Service, User Authentication ＆ Message Integrity Service and Non-Repudiation Service among the various Security Services. This system support XML message format and EDI message, WEB Data and Private Format Data, etc.

Product catalog information is the most important factor to make customers purchase the product for various B2B or B2C businesses provided on the Internet. As catalog information differs from company by company, it cannot provide common criteria standard to customers to make decisions. Therefore, it is necessary to develop a platform independent system, which integrates incompatible data from each company' catalogs and manages its database. This paper describes the integrated E-catalog system made up DB module, catalog management module, and interface module. This system allows customers to view standardized product catalog information from different companies with real -time updates, and also provides extensibility, flexibility, and interoperability for the effective E-Business management.

최근 정보기술, 정보통신기술등의 발달로 기존의 상거래 방식과는 많이 다른 방식의 거래가 이루어지고 있다. Electronic Commerce의 활성화는 가상상점(Electronic Shopping Mall), 전자지불체계 (Electronic Payment System), Web EDI 등 인터넷을 기반으로 한 전자적 경제활동을 다양하게 하였다. 이러한 EC의 한 패러다임으로 이동 상거래 방식이 등장하게 되었다. 이것이 개방 네트워크와 공중망을 통하여 이용자의 위치, 시간과 관계없이 텍스트, 음성, 화상의 디지털 데이터를 이용하여 기업 또는 개인의 상거래 활동을 정의하는 전자상거래(Electronic Commerce) 방식 중의 하나인 모빌커머스(Mobile Commerce)이다. 본 연구에서는 이러한 모빌커머스가 기존의 인터넷 비즈니스의 한 방향으로서 유, 무선 통신망을 이용한 자유스런 정보의 전달을 통한해 어떤 상거래를 구축하는 것이 성공할 수 있는 것인가 이해하고자 전자상거래에서의 모빌커머스 역할에 대해 연구하고자 한다.

Recently, many companies and consumers are using Internet to sell and buy goods and manage their businesses. And for most companies, they have Electronic Commerce system and Enterprise Resource Planning (ERP) system. But the two systems manage separately and the data are not integrative. So it is hard to mangement the system alike and the costs may be higher than the system which has intergrated information. ebXML-based Electronic Catalog (e-Catalog) can provide intergrated information. In this paper, we took a manufacturing industry company for example. We planned to construct the e-Catalog System, analyze the products of the company as well as design e-Catalog system using ebXML to connect EC with ERPs.

21세기는 고도의 정보화 사회가 될 것이다. 이러한 정보화의 사회의 가장 중요한 요소는 수많은 문서 정보를 전자 문서로 만들고 관리하는 것인데, 최근 들어 OIS(Office Information System), 디지털 도서관, CALS/EC 등의 다양한 응용 분야에서 일한 전자 문서의 저장, 처리, 검색이 요구되고 있다. 이러한 상황에서 다양한 전자 문서의 표준들이 나오고 있고, 그 중 차세대 전자 문서의 표준의 선두로서 XML이 대두되고 있다. 따라서 최근에는 XML 문서를 저장하고 검색하는 다양한 응용들이 개발중이고, 이러한 응용들은 XML 문서의 다양한 문서 정보를 모두 만족할 수 있는 검색 기능들을 요구하고 있다. 본 논문에서는 이러한 다양한 XML 응용들의 요구에 따라서 XML 문서가 지닌 다양한 문서 정보에 대해서 검색할 수 있는 XML 질의 언어의 개발에 목적이 있다.

The population of consumers who purchase goods through electronic commerce(EC) is increasing due In the advance of Internet. They can purchase goods freely without time and space restriction and can have variety of choices of goods. Now most of e-Catalogs rely on the simple texts or images to present information on goods. As such, there is limitation in describing goods in detail, which might not make consumers interested in those goods. To solve the problem, more advanced e-Catalogs are demanded compared with the existing ones, requiring research on the e-Catalog authoring techniques that utilize dynamic multimedia data such as audios or videos in addition to the conventional texts and images. In this paper, we describe development of an e-Catalog authoring tnol that is based on SMIL(Synchronized Multimedia Integration Language) which is one of XML applications.

WebME is an Web-based integrated modeling environment that implements a multi-facetted modeling approach to mathematical model representation and management. Key features of WebME include the following: (i) sharing of modeling knowledge on the Web, (ii) a user-friendly interface for creating, maintaining, and solving models, (iii) independent management of mathematical models from conceptual models, (iv) object-oriented conceptual blackboard concept, (v) multi-facetted mathematical modeling modeling, and (vi) declarative representation of mathematical knowledge. This paper presents details of design and implementation issues that were encountered in the development of WebME.

In this report, we provide the focus on suggesting a method of estimating and measurement of CBM(Customer Behavior Model). Through the use of internet, a new trend of business for e-CRM on B2C Web Site known as EC has emerged. The purpose of this study is to identify the relationship between the customers of a shopping mall and CBM characteristics. It can be used to gain a better understanding of customers. From this we can determine trends, and so refine business toward customer's needs and target new products to particular customer groups. Result shows that there is a significant relationship between the customers pattern of shopping mall and CBM, CVM(Customer Visit Model).
