  • The goal of this study is to seek for the method of effective DB conversion and related system development for the integrated KORMARC Format on the basis of the case of Sogang University Library. Since the integrated KORMARC bibliographic format was established, libraries have been converting bibliographic DB according to the new format. Loyola Library of Sogang University internally proceeded DB conversion using bibliographic DB convertor, which was developed and customized with a system vendor for Sogang University Library. The internal conversion enabled to correct or supplement bibliographic data errors. Besides, it enhanced stability of conversion and shortened the project time by adopting sampling conversion method. It was effective to reduce the additional work for DB quality maintenance, so this kind of conversion is recommendable to the library that has limited manpower for manual data correction.

  • Author co-citation analysis(ACA) technique has been widely used for identifying research areas and trends in a discipline. But this technique has some limitations, mainly due to citation delay, on analyzing current trends and identifying active researchers. In this study, a new method, named as Bibliographic Author Coupling Analysis (BACA), is suggested for overcoming those limitations of author co-citation analysis. BACA is based on Kessler's bibliographic coupling approach and focuses not on documents but on authors. Simply stated, BACA technique assumes that those likewise citing authors have the same research interests. For the purpose of comparing with author co-citation analysis, two preceding studies with author co-citation analysis are reconsidered and re-examined using BACA. The comparing results can be regarded as promising the usefulness of BACA in analyzing current research trends and identifying active researchers.

  • Library of Congress introduced BIBFRAME as a new bibliographic framework to enhance web accessibility of bibliographic records and their integration to Web of data. This study introduces BIBFRAME model and its current status, reviews BIBFRAME classes and properties, and presents a mapping between MARC21 and BIBFRAME. The study aims to help the understanding the deployment of BIBFRAME in bibliographic description. BIBFRAME categorizes bibliographic entities into Work-Instance, and employs RDF/XML and URIs to identify resources and specify semantics of the resources on the Web. It also suggests an Annotation entity to provide additional information produced by users and external organizations. BIBFRAME is significant in that it presents a new paradigm of bibliographic description and expands users' information discovery in the context of Linked Data. Continuous researches are required to support its content model agnostic application to diverse resource type, which may entail a modification of BIBFRAME model and vocabulary. It also calls for guidelines for using the complicated vocabulary in a coherent way.

  • With purpose of improving library technology, one of the core elements of library automation technology, are suggested. The results of the study revealed article database standards briefly described as follows: First, database concerning articles in serials are generated from previous indices & abstracts journals. Second, bibliographic elements of ten representative domestic and international bibliographic database systems showed many dissimilar descriptive field types, as well as differences in entry orders and details. Third, database standards or guidelines were non-existent in domestic and international bibliographic database agencies, and different format have been adapted among those agencies. It is strongly recommended that all library should create a plan for adapting internationally standards in data input format as well as output format. Fourth, conforming with ISO 690 bibliographic descriptions, their ten components will be adapted as the basic framework for building the database and appropriately select additional seven data components of total 17 categories.

  • This study was to suggest the creation of hybrid bibliographic records in complicated bibliographic environment applying both AACR2 and RDA for uniform display and correct search. The literature reviews and case studies were used as the research methods. In case studies, Kent State University, University of Houston as the libraries, and Backstage Library Works as algorithm converting to hybrid records were surveyed. For creating the hybrid records, it was needed to differentiate hybrid records and born RDA records, to keep the data that appeared in 250 tag without spelling out edition data, to maintain 260 tag instead of converting 260 tag to 264 tag, and last to design mapping table for converting GMD to CMC. This study would suggest uniform display and search through hybridization of bibliographic records of foreign resources.

  • 전차 선로용으로 적용되는 직류 피뢰기의 설계 기술을 소개하였다. 현재 국내에 사용되는 전차 선로 서지 보호용 직류 피뢰기는 전량 수입에 의존하고 있다. 안전한 피뢰기를 설계하기 위해서 적용 구간의 임펄스 서지 환경을 파악하고 이에 맞는 적절한 내량의 피뢰기를 설계하는 것이 요구된다. 특히 직류 구간의 경우 과도 서지 발생의 형태가 기존 계통 환경과 다르기 때문에 피뢰기 보호범위와 정격의 설정에 주의가 요구된다.

  • Surge Protective Device(SPD) is installed by increasing information and communication equipments and home network equipments by individual home, and the amount of SPD used is increasing by revision industry regulations and strengthening equipotential grounding system. Parts of SPD installed in residential distribution board has ZnO varistor, voltage constraint type devices, but it is exposed to Temporary Overvoltage Characteristic. This thesis analyzes products through Thermal Stability test for SPD for general house and suggests the better method. As results of analysis, Gas Discharge Tube(GDT) to cut off from a leakage current and more than two kinds of safety devices to protect Thermal Runaway were needed.

  • Generally, speed control for Induction motor widely used in industrial field is accomplished by commercial inverter. Induction motor driven by commercial inverter causes the micro surge voltage because of high speed switching of inverter. Micro surge brings about not only the breakdown of motor but also noise in PLC control system. And they court the enormous interference in activity for production. In this paper, we suggest the suppressible countermeasure for the breakdown of motor after the consideration of productive mechanism about micro surge. Experiment is performed by inverter with LCR filler in its output terminal. As a result, we confirmed that micro surge voltage is reduced. And the suppressible countermeasure for the noise of PLC control system is suggested by theoretical consideration.

  • 정보 기술의 발달로 문헌정보의 양이 증가하고 있지만 정확하고 빠른 정보를 지역적으로 분산된 서지정보 데이터베이스에서 찾기에 이미 개발된 방식으로는 시간이 많이 걸린다. 현재 사용중인 텔넷(telnet)을 통한 방식이나. 웹/CGI 기술을 이용한 방식은 문헌정보가 존재하는 각각의 서버를 사용자가 한번에 하나씩 접속하여 검색을 해야 하므로 검색시간이 많이 걸릴 뿐 아니라, 사용자는 각 서버마다 상이한 검색방법을 익혀야 한다. 최근에 이러한 단점들을 개선하기 위해 한곳에서 종합적인 서지 및 본문정보검색을 하는 통합 검색시스템이 중앙 집중형 시스템을 모델로 하여 구축되고 있으나 이 방식 역시, 자료의 불일치성, 시스템 공장과 과부하등 여러 문제점들을 내포하고 있다. 따라서 본 논문에서는 이러한 문제들의 해결책으로 분산 서지정보 통합검색시스템 DBIRS를 제안하고 구현한다. DBIRS는 웹 환경하에서 CORBA 기술과 Java언어를 이용함으로서, 단일 사용자 인터페이스로 병렬 복수질의를 수행하여 동시에 각 도서관에서 자료를 찾을 수 있다. 또한 객체를 기반으로 하는 표준 모델을 사용하여 소프트웨어의 개발과 확장을 가능하게 하고, 향후 멀티미디어 데이터나 웹과 같은 비 정형 데이터 시스템과의 통합을 쉽게 해준다.
