  • This study intends to investigate the processing of the bibliographic relationships in the MARC formats based on the analysis to the related cataloging rules. In the traditional cataloging rules, many methods are used to process the bibliographic relationships(vertical, horizontal, and chronological), including analytics, references, notes, and independent entry. Linking entry fields in the MARC formats have been introduced mainly to process the chronological relationship in the serials, but later expanded, as a chronological in MARC format, to include other relationships applied to all other materials. Comparative analysis on the linking entry suggests that there are rare differences between UNIMARC and USMARC formats except the terminology and display constants, and that it is desirable in the KORMARC and JAPAN MARC to introduce the linking entry more comprehensively.

  • 본 연구에서는 일반 산업현장에서 동력원으로 가장 편리하게 사용하고 있는 장치인 모터의 결함을 사전에 모니터링하기위한 연구를 수행하였다. 기존의 EOCR(electronic over Current relays)을 통해 모터의 전기적 결함에 따른 모터보호 및 전기적 결함측정뿐만 아니라 모터의 절연저항, 구동시간, MC(magnet contactor) 접점횟수, 베어링온도측정, 모터회전수 측정 등 전기적 결함과 기계적 결함을 동시에 모니터링 할 수 있는 다기능 모터보호장치를 구현하고자 하였다. 이를 위하여 다기능 모터보호장치의 데이터입력 및 제어장치, 디스플레이 및 인터페이스 장치를 구현하였고, 실제 MCC시스템과의 연동을 통해 동작특성평가를 수행하였다. 인위적인 전기적 결함 및 기계적 결함을 유발시키고 이를 검출하는 모의실험을 수행한 결과 전기적 결함과 기계적 결함 각각에 대해 100% 검출 가능함을 확인하였다.

  • 'One Book, One City' reading campaign is one of the major reading campaigns, successfully conducted by public libraries in this century. The purpose of this study is to evaluate the significance of 'One Book, One City' reading campaign, as an innovative, continuing, and collective reading campaign by analyzing its growth and diffusion during the past six years. Also, analyzed are the themes. genres, and publication dates of the books and the characteristics of authors selected for 'One Book' in order to understand the cultural, social, and community-wide trend and objectives of 'One Book, One City' reading campaigns. An analysis of lists of 'One Book, One City' Reading Promotions Projects' available from the website of the Library of Congress, the Center for the Books, and bibliographic records of ninety books from LC OPAC, shows the preference for books recently published, significance of biographies and biographical fictions, and focus on the themes which help people better understand a multi-cultural and multi-racial society.

  • The purpose of this study is to examine the current status of user-contributed reviews for the Next Generation Library Catalogs, and the potential impact of user reviews available from the external sources, including Amazon.com and GoodReads.com. During the period of February 16th through April 4th, 2012, the number of holding libraries and user-contributed reviews, tags and reading lists of ten selected books were examined from the WorldCat. Also the user-contributed reviews for the same books available from Amazon.com and GoodReads.com were examined, and a case of reviews for one book was analyzed. The result shows that only a few users participated in the WorldCat, and user-contributed reviews were rarely used, when compared with tags or reading lists. Several hundred to thousand user-contributed reviews for the same books were available from Amazon.com and GoodReads.com directly linked with bibliographic records. A case of one book from Amazon.com reveals the possibility of distorting the function of user-contribution. With the introduction of the function of user-contribution, it is expected that its growth rate should be carefully observed and its potential impact on users should be thoroughly and systematically analyzed in the near future.

  • This study came up a library thought and the theory of cataloging through analyzing the life and writings of Seymour Lubetzky who founded the principals of cataloging in the twentieth century. This study investigated the historical social, ideological, and cultural context, using a literature survey and the methodology of historical research. Moreover, this study aimed a comprehensive research based on the results of domestic and foreign fragmentary studies, and analyzed the effects of Lubetzky's thought of cataloging. Thus, this study found Lubetzky's library and cataloging thought. The theory of cataloging that analyzes the above findings is the design of cataloging rules and a bibliographical relationship establishment. First of all, the principles of descriptive cataloging should contain the necessity, simplicity, unity, consistency, finality, and the characteristics of interrelations, and clarify the purpose of cataloging. The bibliographical relationship is built on dividing a work as an intellectual product into a book as a physical substance. Moreover, a basic entry is entered on the basis of author names for planning the concentration of works, and a corporate name and an anonym are contained in the author names for extending the concept of author.

  • This study examined the characteristics of Buddhist books printed using metal type during the Joseon Dynasty period from a bibliographical perspective. It was found that there are 36 kinds of Buddhist books published using metal type during the Joseon Dynasty period that currently exist. In terms of the types used for publication, there were 9 kinds of printed editions by Gapinja, 13 kinds of printed editions by Eulhaeja, 2 kinds of printed editions by Jeongchukja, 3 kinds of printed editions by Eulyuja and 9 kinds of printed editions by Jeonsaja. Among them, The Buddhist books printed using Eulhaeja were 36 % of total with the highest quantity of 13 kinds. In terms of periods of publication, it was found that 27 kinds and 9 kinds of Buddhists books were published respectively in the first and latter parts of Joseon Dynasty periods. Among them, there were 19 kinds of metal type book editions published during the King Sejo period that occupied 70% of total. It appears that such phenomenon was a result of King Sejo's abnormal enthronement and Buddhism-friendly tendency.
