This study aims to evaluate the quality of Bibliographic database : The Union Catalog system(UNICAT) and Korean Library Information System Network(KOLIS-NET). The seven criteria(Coverage, Accuracy, Completeness, Currentness, Consistency on the quality of data itself and easy of use, Customer Support on the quality of database service) are used to measure their quality. The purpose of this study was dignose the quality of two bibliographic database mentioned above and analyses the measured result of quality comparatively and to find out the problems of them and also to provide possible suggestion for their improvements.

Customer sensibility based recommendation agent system was developed to tailor to the customer the suggestion of goods and the description of store catalog in on-line shopping mall. The recommendation agent system composed of five modules and seven services including specialized algorithm. This study was to investigate the effectiveness of the customer sensibility based recommendation agent system in on-line shopping mall. This study asked 30 male and female students to perform the task in on-line shopping mall and facilitated them questionnaires. The questionnaires were administered to subjects to measure quality precision, ease of use, support of buying, purchasing power, future intention of the system. The study revealed that good part of the subjects positively evaluated the customer sensibility based recommendation system except for ease of use. The study on usability of the recommendation agent system has need to be performed in next. This paper shows that the satisfaction and the buying power of customers may be improved by presenting customer sensibility based recommendation in on-line shopping mall.

본 연구는 공간데이터 동기화 표준 프로토콜 명세인 SyncML(Synchronization Markup Language)을 이용하여 모바일 장비와 서버사이에 공간데이터를 동기화 구조를 정의하여 상호운용성 확보를 위하여 기존에 사용되어온 GML(Geographic Markup Language) 데이터와의 통합 및 다양한 데이터 소스에 대한 접근 가능성을 제시한다 뿐만 아니라 Metadata 및 Catalog Service를 이용한 공간데이터 동기화 시스템을 제시함으로써 분산되어 있는 다양한 형태의 공간데이터, 비공간 데이터의 관계성을 고려한 데이터 연동을 가능하게 한다.

최근 인터넷에서 문서 포맷의 기준으로 XML이 각광을 받고 있으며 XML schema를 통하여 DTD에서는 할 수 없었던 부분을 할 수 있게 되었다. 또한 e-카탈로그에서 XML 문서의 사용이 급증하면서 XML 문서의 설계가 점차 복잡해지고 XML schema 설계가 DTD보다 한층 더 복잡하게 되었기 때문에 XML schema 모델링이 중요한 문제로 대두 되었다. 이에 본 논문에서는 복잡한 XML 문서를 체계적이고 구조화하기 위하여 XML 문서를 UML로 설계하고 UML 모델링 정보를 변질과 누락 없이 추출하기 위하여 REI를 이용하여 UML 모델링 정보를 추출하여 XML로 변환하였다.

In this paper, we propose a framework for synchronization of spatial data between mobile devices and a server by using SyncML(Synchronization Markup Language) that is standard specification for synchronization protocol. We used GML (Geographic Markup Language) to support interoperability of spatial data between various data sources. We also used metadata and catalog service to access and integrate distributed spatial data, considering relationships of spatial data and non-spatial data.

Discovery of association rules has been used useful in many fields, especially in the fields of the inventory display, catalog design and cross selling. In previous works, all transactions In the database are treated uniformly. In this paper, we present a method for partitioning transactions in the database using time weights. Transactions are assigned different weights as time goes on. Examples show that these method provides purchasing patterns in the database as well as finding association rules.

Defense analysis & evaluation includes menace analysis, validation analysis, problem analysis, scientific technical analysis, technical trad-off analysis, alternative analysis, cost analysis, etc. Reliable related data is required to perform these analysis activities efficiently. but in case of these defense analysis & evaluation data acquisition system, the data is insufficient and scattered about each organization. the data of database system is also not utilized sufficiently. abroad technical data is also low level data such as catalog or military officer's collection. therefore, this paper propose defense analysis & evaluation data acquisition system by systems engineering process. we also propose construction method of data acquisition system.
