XML이 웹에서 데이터 교환의 표준으로 부각된 이래 전자 거래의 핵심 요소로 자리 잡으며 유비쿼터스 컴퓨팅 환경에서도 XML 데이터에 대한 효율적인 질의 처리에 관한 연구가 발하게 이루어지고 있다. 최근에는 XML 문서를 XML 조각으로 분할하여 스트리밍하고 이동 클라이언트에서 이를 수신하면서 질의 처리하는 기법이 제안되었다. XML 조각 스트림에대한 질의 처리는 스트림을 구성하는 각 조각의 전송 순서에 따라 평균 접근 시간에서 큰 차이를 보인다. 따라서 질의 성능을 높이기 위한 효과적인 XML 조각 스트림 구성 방법이 요구되며, 튜닝 시간의 단축을 통해 에너지 효율적인 질의 처리를 가능하게 하는 인덱싱도 요구된다. 본 논문에서는 사용자 질의 빈도와 질의 처리 시 접근되는 XML 조각의 크기 및 중복에 기반을 둔 XML 조각 스트림 구성 및 능동 XML 형식의 인덱스 구성을 제안한다. 구현 및 성능 실험 결과 본 논문에서 제시한 기법이 다양한 사용자 질의 집합 및 빈도에 대해 기존의 XML 조각 스트림 구성 기법에 비해 접근 시간 및 튜닝 시간 양면에서 모두 우수함을 확인하였다.

The rapid expansion of regionalism has resulted in the creation of blocs of the global economy, so that those countries not belonging to one or more blocs can be discrimiated. Though signed on the bill of FTA with Chile, Korea is actually alienated from major stream of the blocs. Therefore, Korea government makes efforts to contract more FTAs with countries such as Singapore and Japan, others. FTA is believed to be an important method to secure export and national competitiveness. Therefore, we need to exactly understand critical issues and the long-run effort of FTA. This paper tries to find out important issues and potential strategies relating to electronic commerce in Korea's FTA with other countries. In these means, relationship between FTA and e-Trade are closely related to global business chance. In these means, we should use FTA potentials for encouraging global commerce by e-Trade and develop e-FTA in the foreseeable future.

Collaborative filtering is one of the popular techniques for personalized recommendation in e-commerce. In collaborative filtering, user profiles are usually managed per product category in order to reduce data sparsity. Product diversification of Internet storefronts and multiple product category sales of e-commerce portals require cross-product category usage of user profiles in order to overcome the cold start problem of collaborative filtering. In this paper, we study the feasibility of cross-product category usage of user profiles, and suggest a method to improve recommendation performance of cross-product category user profiling. First, we investigate whether user profiles on a product category can be used to recommend products in other product categories. Furthermore, a way of utilizing user profiles selectively is suggested to increase recommendation performance of cross-product category user profiling. The feasibility of cross-product category user profiling and the usefulness of the proposed method are tested with real click stream data of an Internet storefront which sells multiple product categories including books, music CDs, and DVDs. The experiment results show that user profiles on a product category can be used to recommend products in other product categories. Also, the selective usage of user profiles based on correlations between subcategories of two product categories provides better performance than the whole usage of user profiles.

This study has analyzed the international trade flow of medical devices in Korea, China, and U.S. more theoretically and systematically through a mutual connection of the medical device export structure of Korea and the import structure of China and U.S. organically, with an intensity approach on the bilateral international trade flow. Also, it is meaningful to find a solution to boost exports of Korea to China and U.S.. Therefore in this study, we recognize the importance of the medical device market in China and U.S., which is the main competition for Korea and its market, and look into the trade situation of these three countries. We also look into the relative market stream and the trade intensity of the main medical devices in Korea, China and U.S., and seek measures for the steady growth of the medical device market in these three countries.

The purpose of this paper is to examine whether the international electronic payment system through IDENTRUS can be active in the future or not. For this purpose, we have reviewed the various aspects of the typical systems : their types, operational mechanisms and actual limitations in real trade. Then we have proceeded to examine the distinguished features of IDENTRUS in terms of operational procedures and characteristics by comparing to other systems. Specially as the preconditions of activation, the possibilities of cost down, time reduction, risk hedging and operational efficiency have been studied. Thus we are not sure that the IDENTRUS will have a position as a main stream in the future electronic payment system, but this system would contribute positively to the establishment of electronic payment system if some functional additions will follow.
