Electronic catalog contains ich semantics associated with products, and serves as a challenging practical domain for ontology application. Ontology is concerned with the nature and relations of being. It can play a crucial role in e-commerce as a formalization of e-Catalogs. Description Logics provide a theoretical core for most of the current ontology languages. In this paper, we present an ontological model of e-Catalogs in DL. We take an Extended Entity Relationship approach for conceptual modeling method, and present the fundamental set of modeling constructs and corresponding description language representation for each construct. Additional semantic knowledge can be represented directly in DL. Our modeling language stands within SHIQ(d) which is known reasonably practical with regard to its expressiveness and complexity. We illustrate sample scenarios to show how our approach may be utilized in modeling e-Catalogs, and also implement the scenarios through a DL inference tool to see the practical feasibility.

고객이 요구하는 정보를 효율적으로 제공하기 위한 전자 카탈로그를 구축하는 것은 e-business의 성공의 핵심적 요소이다. 우수한 상품 판매 기술을 이용하여 고객의 판매 결정을 촉진하는 전자 카탈로그가 있는 반면, 그렇지 않은 경우는 사업적 손실과 법적인 분쟁까지 초래하기도 한다. 전자 카탈로그가 전자 상거래 사이트의 중심 요소임에도 불구하고 이제까지 학문적, 실용적 분야에서 전자 카탈로그의 평가 방법에 관한 연구는 찾아보기 힘든 상황이다. 따라서 이 연구에서는 우선 효과적인 전자 카탈로그 구축을 위한 요구사항을 도출해 내고 그것을 전자 카탈로그 평가 기준으로 적용하여, AHP(계층적 분석 방법)를 사용해서 평가 기준간의 상대적 중요도를 개발해 내는데 목적이 있다. 그 평가 기준의 상대적 중요도는 기업이 전자 카탈로그를 구축할 때 중점을 두어야 할 사항을 결정하는데 기준을 제시해 줄 것이다. 이 연구의 결과는 평가는 물론 효율적인 전자 카탈로그의 개발을 위한 지침을 마련해 줄 것이다.

We can buy products everywhere from Web-based shopping mall using desktop, cellular phone or PDA. To guarantee the various services for different equipment, shopping mail systems should allow a lot of different size or quality of images to provide a good service to their customers. Despite of same product image, each shopping mall saves the image in its storage space individually. Furthermore, all the product images in each shopping mall are stored as images of different quality. It may waste resources of shopping mail server and bring us developmental overhead. It is difficult to update all the images for product that is used by distributed e-catalog in everywhere. In this paper, we extended the proposed Web Image Server (WIS) for sharing one image with all clients and processing Image dynamically, so that we strengthened the function of managing shopping mall as a client of WIS and added the function of recording clients'log file and image catalog for shopping mall. We measured the response time from WIS and conventional e-Commerce site using by WAS which is one of the stress test tools for Web application. Furthermore, we measured WIS responses image requests in reasonable time when the current user is increased.

Build-to-Order (BTO) capabilities enable manufacturing firms to design, produce, and deliver a high volume of differentiated products that meet specific customer needs in timely manner as well as at close to mass-production prices. Aim of BTO is to simultaneously achieve customer responsiveness, cost efficiency, and high volume production. This paper attempts to define the BTO system and suggests the critical components for its realization. A case study is also described to show the impact of a successful BTO implementation.

최근 정보화의 추세를 보면 인터넷의 사용이 다양하게 발전하고 있다. 회사간에 정보 인프라를 통해서 거래를 할 수 있는 e-Catalog의 필요성도 급속하게 대두하게 되었으며 e-Catalog는 단순한 상품 전시 수준에서 벗어나 기업활동 전반에 걸친 XML 기반의 B2B e-비즈니스로 확대되어 가고 있다. 한 걸음 더 나아가 e-비즈니스는 앞으로 전 세계의 모든 영역으로 급속히 확산될 것으로 예상된다. 따라서 XML 기반의 B2B e-Catalog가 미치는 전자상거래상의 파급효과를 검토하고, Java를 활용한 XML 기반의 B2B e-Catalog의 관점에서 기존의 Catalog를 재조명해보는 것이 필요하다고 본다. 논문에서는 특히 기업과 공공부문 상품에서의 XML 기반의 e-Catalog 유용성에 대해 논의하려고 한다.

This study was carried out to examine the e-Business status of Korea Forest Product Industries and to propose the development. The use level of e-Business in korea forest product industries have stayed in internal company information network integration stages. But lots of companies located in the insufficient of e-Business models, the lack of qualified staffs, and the shortage of e-Business operating technology and implementation. As the result of this study, the followings must be considered; 1. For the promotion of e-Business use, it is needed to maintain price competitiveness, quality competitiveness, and market correspondence capacity. 2. For the settlement of e-Business models, it is important to connect information network among cooperation companies as like forest products standardize, common database, and standard electronic catalogue. Also, it needed developing program to strengthen the competitiveness of forest product industries, expanding to outsourcing and affiliated companies.
