The primary questions addressed by this research are the followings: Have the OPAC interfaces of children's libraries been designed user-friendly; What difficulties have OPAC searchers experienced in using OPACs; How do they perceive the system after searching it; Through the answers of those questions the problems of OPACs for children as searching tools have been grasped and recommendations have been suggested in order to improve the OPAC interfaces. An experiment was conducted and 28 children of grades 4 to 6 performed 5 searching tasks. The searching behavior of OPAC searchers has been analyzed thoroughly. The data of their perceptions about the system was collected through a questionnaire after completing the tasks.

This study attempts to reorganize the knowledge classification system for the research fields and majors in education by designing a new classification schedule. Content analysis of the majors and curriculums in the universities and major areas of the academic professors in Korea, and the comparison with the various headings in several classification systems for research fields were carried out. Based upon the comparison with library classification systems and reviews and opinions of subject specialists in major disciplines, finally, a knowledge classification system composed of three parts - schedules, tables and a relative index - was presented. The proposed classification scheme was tested for classifying the research projects listed in the 1998 catalog of the academic research funded by Korea Research Foundation. Also, several ways for developing a more useful knowledge classification scheme to organize disciplinary information effectively and to encourage interdisciplinary research were suggested.

Bibliographic Network has been a goal about not only to support resource sharing within libraries but also to pursue economic efficiency of cataloging. But nowadays, as resources in diverse media and format have been poured out, printed resources based union catalog should change to new resources finding system which include diverse type of resources. This study analyzes changing factors of bibliographic network and strategies for LC, NII, OCLC, NLA who try to turn over a new service. Finally basis on these findings, suggest task for Korean new generation bibliographic network service which is focused on introducing new collaborating model and developing new resource finding system.

지리정보시스템에서 사용되는 공간데이터의 특성은 양이 방대하고 구조가 복잡하여 데이터를 구축하는데 많은 비용과 노력이 요구된다. 또한 각 지리정보 응용시스템마다 특정한 포맷으로 데이터를 구축, 사용하는 실정 때문에 기존에 동일한 데이터가 구축이 되었더라도 재사용하지 못하고 다시 재 구축하여 사용하였다. 대부분의 지리정보 응용시스템에서 기존의 데이터를 재 사용지 못하고 전체 예산의 60% 이상을 데이터 구축에 중복 투자하는 문제점이 존재한다. 또한 데이터구축의 문제점뿐만 아니라 소프트웨어적으로 시스템 환경에 의존적으로 구현되어 시스템 환경이 변하는 경우에 시스템 자체가 수정되거나 재 구현되어야 하는 문제점도 존재하였다. 본 논문에서는 이러한 데이터 중복구축 및 투자와 시스템 의존적인 구성의 문제점들을 해결하기 위해 기존에 존재하는 데이터를 온라인상에서 검색하여 사용자가 재 사용할 수 있도록 OpenGIS에서 제안한 CatalogService를 구현하고 분산된 상호 이질적인 환경에서 서로의 데이터를 공유하고 연동하는 모델을 제안하고 구현하기 위해 WWW, COM, CORBA 기반으로 시스템을 구현하였다.

The classic graphical method to determine the epicenter uses differences between the arrival times of P and S waves at each station. In this research, a robust approach is proposed, which provides a fast and intuitive estimation of earthquake epicenters. This method uses an empirical relationship between epicentral distance and traveltime of the first arrival P phase of local or regional earthquake. The relationship enables us to estimate epicentral distances and draw epicentral circles from each station with P-traveltimes counted from a probable origin time. As the assigned time is getting close to the origin time of the earthquake, epicentral circles begin to intersect each other at a possible location of the epicenter. Then the possibility of the epicenter can be expressed by a function of the time and the space. We choose the location which gives the minimum standard deviation of the origin time as an estimated epicenter. In this research, 918 P arrival times from 84 events occurring from 2005 to 2006 listed in the KMA earthquake catalog are used to determine the empirical P-traveltime function of epicentral distances.

In the recent you, as the development of computer network and web, the amount of electric document exchange is dramatically increased through B2B, B2C, electric bid and et cetera. The medical world also needs to share and exchange good information for medical treatment like H2C(hospital to hospital), H2C(hospital to company). In this paper, we design medical information model using DTD and inplement medical information support system based on xml and xslt.

The Temporal Database Management Testbed supports valid and transaction time. In this paper, we discuss the design and implementation of a testbed of a temporal database management system in main memory. The testbed consists of a syntactic analyzer, a semantic analyzer, a code generator, and an interpreter. The syntactic analyzer builds a parse tree from a temporal query. The semantic analyzer then checks it for correctness against the system catalog. The code generator builds an execution tree termed ann update network. We employ an incremental view materialization for the execution tree. After building the execution tree, the interpreter activates each node of the execution tree. Also, the indexing structure and the concurrency control are discussed in the testbed.

This study proposes a 'Bibliographic Universe Relationship Vocabulary'(burv) using the RDF/OWL Object Property under the SPO predicate logic according to the relationship type among all entities of bibliographic universe and implemented a 'relationship ontology system' to establish a new cataloging business domain called 'Relationship Description Cataloging' based on the ontology.

In accordance with the recent expansion of collection operation of independent publications through public libraries, this study conducted a status analysis on independent publications collection in public libraries and in-depth interviews with staff in charge of independent publications in order to suggest ways to effectively manage independent publications. As a result, it was deduced that the measures needed for effective management of independent publications are construction of joint cataloging system for building and sharing independent publications catalog in public libraries; platform for collecting various information of independent publications; support for ISBN, ISSN, CIP issuance of independent publications; and improvement of distribution system.

The study designs and implements a KORMARC/EAD integrated system for the Myongji Digital Library Collections. The purpose of this paper is to design the metadata to Myongji Korean History Collections to provide digital information of high quality to clients, and to develop and implement a model for managing digital library collections. In order to test the model and the quality of the derived metadata, we built a metadata management system, which is connected to the existing KORMARC system. The system consists of two modules- a retrieval and an input module. While in the retrieve mode, one can retrieve KORMARC records of books and archival items, with links to modified EAD files for archival items or to image files for books, in the input mode, one can type two types of data such as a catalog data and an inventory data. Finally, we evaluated the proposed system via mail questionnaires, and propose three suggestions to make this system a much more comprehensive and effective system.
