  • The tendency of lightning surge to propagate is a eared variously depend on the power system and subject equipment of protection. However, looking into the subject equipment with the lightning surge, the invasion route of lightning surge can be divided in between the two lines of power, between the power line and the ground, the power line and the PE conductor, between the neutral line and the ground and the like. In addition, in the event of the communication equipment, there exists the route of lightning surge incoming from between the communication lines, the communication line and the ground in addition to the power lines. In this study, the tendency of propagation of lightning surge penetrated on to the subject equipment is analyzed through the empirical experiment in accordance with the ground method by using the independent ground, common ground and bypass arrester ground for safety improvement in power lines.

  • The purpose of this study is to investigate how individuals assess Chinese, Japanese, and Korean (CJK) transliterated bibliographic information on current library catalogs. Two separate studies, a survey and an experiment, were conducted using the WorldCat system. Users noted that Romanization has many issues which can inhibit user‘s ability to understand the transliterated bibliographic information even when it is in the person’s own native language and even when the individual had extensive experience with transliteration systems. The experimental results also supported these findings: participants had better results and satisfaction when looking for information written in English than when searching for transliterated information written in their native language. Implications for future research suggests a need to investigate user preferences for translation vs. transliteration of bibliographic information. This study proposes consideration of using English translation as a parallel link with CJK Romanization for bibliographic information.

  • Disagreements between the technical environment and the conventional library catalog have caused a re-clarification of International Cataloguing Principles (ICP). Review is under way to finalize the publication of RDA (Resource Description and Access) in late 2009 by the Joint Steering Committee for Development of RDA. The impending RDA is based on FRBR (Functional Requirements for Bibliographic Records) which re-explains the bibliographic universe focused on entities, attributes and relationships between resources, but tries to maintain MARC as an encoding format for RDA. In this study, firstly FRBR, ICP and RDA were analyzed. Secondly, we propose 3 scenarios of RDA implementation: the future cataloging system based on the FRBR Entity, using a semantic web structure, and the scenario using the existing MARC format with some small changes. Finally, by examining response patterns of overseas bibliographic institutions, we present a set of urgent issues for future directions of bibliographic contro in Korea which includes, but not limited to, relationship between RDA/FRBR and KCR (Korean Cataloging Rules), continuation of KORMARC and authority control.

  • This study analysed work types of Chinese bibliographical records based on FRBR model to identify how many useful data there are in bibliographical records and how much difference in usefulness there is according to themes. For the purposes, the study randomly extracted samples of 2,200 Chinese books with 100 cases of 22 kinds from "Chinese Library Classification" through National Library of China's OPAC, targeting Chinese books collected by the National Library of China to analyse the work types of Chinese bibliographical records and their usefulness in application of the FRBR model according to themes and data types. The results are summarized as follows: Firstly, in applying the FRBR model for Chinese bibliographical records, 18.6% was considered as useful works for which simple work was added to complex work. Secondly, although it is a fact that usefulness is higher as bibliographical relations are more complex, only works by famous people collected in 'Marxism-Leninism'(A) and some classics and modern masterpieces collected in 'Literature'(I) have diverse versions of works such as sequels, revision, reproduction, adaptation, and critical books. However, if criticism, review, explanation and bibliographical introduction are included in specific subjects of 'Military'(E), 'Language and Words'(H), 'Literature'(I) and 'Comprehensive Book'(Z), it was clear that their usefulness is relatively high.

  • The purpose of this study is to identify the problems of describing bibliographic elements such as edition, impression, and year of publication in the current Cataloging Rules, and to present improvements to the KCR and the KORMARC Format. According to changes in the information technology environment in the library, the level and scope of the cataloging that can be provided to users should be adjusted. As data is diversified and descriptive method of metadata develops, the development of bibliographic elements and the change of the descriptive method are changing the framework of the existing standardization. As a research method, we will examine the concept of edition and impression, examine the transition process of description of edition and impression targeting KCR. And we would like to present the methods of bibliographic description to be added or modified through cataloging examples, and examine the format reflected in KORMARC. This study is intended to be limited to the descriptive form of books. The bibliographic elements of the entry in the library must be fully consistent with the bibliographic elements of the material to be catalogued. This study suggests an improvement to the cataloging rules. First, the edition of the cataloging rules shall describe the edition statement and the impression statement. In addition, the description of the year of publication describes the latest year, not the first year of publication of the edition of the material to be catalogued. The descriptive scope of the year of publication is extended to the month of publication. Second, in the KORMARC format, the description of impression in edition statement is given to the identifier in the 250 field, and is numerically described as the second impression. When presenting the month and year of publication, one identifier in the field 260 describes the year of publication and the other identifier describes the month of publication. The description for the month and year of publication is stated the latest month and year on the title page and the colophon of the publication.

  • The purpose of this study was to identify bibliographic characteristics of the top level articles among KCI indexed academic articles. Unlike the existing analysis on citation and most-cited articles, this study analyzed their bibliographic characteristics. The 3,453 articles were collected from 17 social science fields in KCI. The characteristics of authors, institutions, publications, journals, and citations were analyzed. According to the result of the analysis, there was a difference in the ratio of single authors to co-authors and in the number of co-authors. The authors were mostly single authors or two co-authors. In general, the percentage of authors of one article was high. Second, the types of institutions were mostly universities, and there were differences in the number of institutions with authors in each field. And the frequency of the authors' affiliation appeared uneven. There were a number of excellent research institutes and authors depending on the field. Third, the average of years to take to become the top articles for publication was 11 years in 2018. Fourth, most of the published journals were KCI registered journals, and the influence of the journals was not a factor. Fifth, there were differences in the number of cited counts between fields. This study is meaningful to grasp the influencing factors on the bibliographic characteristics of the most-cited articles for the social science field.
