In this study, we constructed a hypertext-based bibliographic information retrieval system, which is very usell tool to browse and retrieve structured data. We minimized the problem of the use; s disorientation with the keyword retrieval technique. We also presented the potential advantages of this system which could be obtained by implementing it on WWW.

The AC power lines and signal lines of info-communication networks are muted on overhead poles and are exposed to lightning strikes. Due to the potential difference between groundings of the AC power lines and telecommunication lines, the electronic equipments connected to the telecommunication lines can easily be damaged by lightning surges. In this work, in order to develop the reliable ways to protect information and communication facilities from lightning surges, the reliability and performance of surge protective devices were experimentally investigated in actual-sized test circuit. The operation behaviors of surge protective devices against lightning surges from the AC power lines and telecommunication lines and the coordination effects of SPD installation method were evaluated. As a consequence, it was confirmed that the bypass arrester and common grounding system is very effective.

This study aims to investigate bibliometric services practices of foreign libraries by service types and suggest practical considerations for Korean libraries wishing to implement bibliometric services. Through the examination of previous research and library websites, nine types of bibliometric services were identified under two broad categories - education & consulting services and research evaluation & research trend services. According to the service types, a wide range of bibliometric services activities were analyzed and described. Recommendations from the study for service development include: building an institutional repository for scholarly output; developing subject guides and education programs at the initial phase of service and providing more advanced services such as consulting and analysis services at the later phase; identifying the potential service needs of researcher groups.

현대 산업에서 정밀기기와 정보기기의 사용이 증가되면서 전력품질의 중요성이 강조되고 있다. 또한 건축물 뇌 보호 관련 규정이 KS C IEC 62305로 개정피면서 선택사항에 불과했던 내부 뇌 보호 시스템 서지보호기(SPD)의 설치가 의무화 되었다. 그런대 사용자들이 실제 이용하고 있는 서지보호기를 현장에 적용하였을 때 많은 문제점이 드러났다. 첫째, 서지보호기를 설치 후 제대로 작동 하는지 동작 상태를 파악할 수 없고 단지 낙뢰가 몇 번 유입되었는지의 카운터 기능의 시각적 판단만 가능하다. 또한 시간이 지나면서 서지보호기의 특성 변화 파악이 불가능하다. 설치 후 제 성능은 얼마나 발휘하는 가를 알 수 없고 LAMP에 의해 SPD의 소손 여부만을 판단할 수 있어 SPD의 교체시기를 알 수 없다. 이런 문제점을 해결하기 위해서는 서지보호기에 유입되는 서지크기, 유입경로 및 횟수를 통한 서지의호소자의 성능에 대한 대책 마련을 가능케 하여 바람직한 서지보호 및 적용이 가능토록 하고자 한다.

In this research, several ways of creating effective STI(Scientific ＆ Technological Information) databases were suggested. We put emphasis on the selection of input data, while on the other was handled, such factors as standardization for data entry, data entry system, etc.. In order to decide priority of target data, the status of document delivery service was analyzed. The result shows that conference proceedings were given priority to academic journals. In case of journals, ranking in the number of documents requested at KORDIC (Korea R＆D Information Center) and 16 Specialized Information Centers was compared with the ranking in citation frequency and impact factor, appeared at SCI.

In accordance with the educational paradigm that values self-directed creative education, school libraries and public libraries emphasize self-directed learning support through curriculum-linked programs as their main tasks. For self-directed learning, it is essential to provide learner-centered educational knowledge information, and there should be abundant textbook-linked references that can deepen and expand the curriculum reflected in textbooks. This study established KDC-linked information related to unit and cross-curricular learning topics through the analysis of elementary school textbooks and curriculum-linked books, restructured KDC system based on major subjects in the elementary school curriculum, and established a curriculum-linked subject information. Libraries can strengthen support for self-directed creative learning for elementary school students in an online environment by linking library content targeted for each user with elementary school education content focusing on learning topics in the curriculum.

Intellectual structure analysis, which quantitatively identifies the structure, characteristics, and sub-domains of fields, has rapidly increased in recent years. Analysis techniques traditionally used to conduct intellectual structure analysis research include bibliographic coupling analysis, co-citation analysis, co-occurrence analysis, and author bibliographic coupling analysis. This study proposes a novel intellectual structure analysis method, Keyword Bibliographic Coupling Analysis (KBCA). The Keyword Bibliographic Coupling Analysis (KBCA) is a variation of the author bibliographic coupling analysis, which targets keywords instead of authors. It calculates the number of references shared by two keywords to the degree of coupling between the two keywords. A set of 1,366 articles in the field of 'Open Data' searched in the Web of Science were collected using the proposed KBCA technique. A total of 63 keywords that appeared more than 7 times, extracted from 1,366 article sets, were selected as core keywords in the open data field. The intellectual structure presented by the KBCA technique with 63 key keywords identified the main areas of open government and open science and 10 sub-areas. On the other hand, the intellectual structure network of co-occurrence word analysis was found to be insufficient in the overall structure and detailed domain structure. This result can be considered because the KBCA sufficiently measures the relationship between keywords using the degree of bibliographic coupling.
