This study intended to make new suggestions by clarifying usefulness of analysis methodology for the intellectual structure of disciplines, which combines author co-citation analysis and author bibliographic coupling analysis. It also aimed to identify the recent research trend and key researchers recently doing research activities actively as well as the intellectual structure in the field of social welfare. It was found to be more efficient to conduct both author co-citation analysis and author bibliographic coupling analysis in order to identify traditional sub-areas of disciplinary subject or the research trend of actual researchers in examining the intellectual structure of a specific discipline.

This study intends to design the bibliographic framework based on IFLA-FRBR model for television program materials and to evaluate this in terms of effectiveness of retrieval and usability of the system. The FRBR model supplies mote suitable bibliographic framework of audio-visual material which has a sufficient hierarchical relations and relative bibliographical records. The followings are research methods designed by this study; (1) The experimental metadata system named it FbCS based on FRBR was developed by using the entity-related database and composed of multi-layed and hierarchy. FbCS is developed through benchmarking of a case study for iMMix model in Netherlands based on FRBR. (2) To evaluate effectiveness of retrieval and usability of FbCS, this study made a experiment and survey by user groups of professionals.

This study examines the concept of the FRBR model of IFLA, which stratifies the bibliographic relationships between related works and bibliographic records and effectively links them, as well as the problems occurring in the applied cases. Moreover, it modifies the FRBR model by accepting the excluding perspectives of main entry heading and introducing ISTC as a linking device of the related work. This study examines the validity of the M-FRBR model by applying it to Korean literature, resettles the data elements of MODS based on the M-FRBR model. and realizes a bibliographic system based on the modified record format.

The KERIS Union Catalog is the largest bibliographic database in Korea. It has over 5.7 million bibliographic records and at present 330 university libraries are participating in shared cataloging services. The database, however, includes various errors and a large number of duplicate data because separate databases from many university libraries were merged without proper quality control in a short period. This study intends to find error data types by analyzing dissertation bibliographic data. The results show that error data are mainly caused by input errors, and the mistakes in using MARC formats and cataloging rules.

Objectives : Every year tens of treatises have been published on the journal of oriental gynecology. But until now there were no papers on the analysis of those treatises and no efforts to evaluate them. Method : To analyze the treatises of journal of oriental gynecology, we examined 19 journals published from 1987 to 2001. There were no rules to analyze treatises, we followed the way of Seo, classifying treatises into bibliographic, experimental and clinical categories. Results and conclusions : 1. Until 1994 most of treatises were bibliographic but from 1995 experimental treatises were increased. 2. Many(29.5%) of them were studied about the diseases in pregnancy, Many(25.4%) of experimental treatises were reserched about the diseases on leukorrhea. 3. In the clinical treatises most of them were case reports. 4. In the bibliographic treatises 90% of them were studied about the classic contents categories. 5. In the clinical treatises the way of treatment showed about same percentage between single herb medication and acupuncture-herb medication complex.

An automatic switch among ensembles of clustering algorithms is proposed as a part of the bibliographic big data retrieval system by utilizing a fuzzy inference engine as a decision support tool to select the fastest performing clustering algorithm between fuzzy C-means (FCM) clustering, Newman-Girvan clustering, and the combination of both. It aims to realize the best clustering performance with the reduction of computational complexity from O($n^3$) to O(n). The automatic switch is developed by using fuzzy logic controller written in Java and accepts 3 inputs from each clustering result, i.e., number of clusters, number of vertices, and time taken to complete the clustering process. The experimental results on PC (Intel Core i5-3210M at 2.50 GHz) demonstrates that the combination of both clustering algorithms is selected as the best performing algorithm in 20 out of 27 cases with the highest percentage of 83.99%, completed in 161 seconds. The self-adapted FCM is selected as the best performing algorithm in 4 cases and the Newman-Girvan is selected in 3 cases.The automatic switch is to be incorporated into the bibliographic big data retrieval system that focuses on visualization of fuzzy relationship using hybrid approach combining FCM and Newman-Girvan algorithm, and is planning to be released to the public through the Internet.

Library communities face many problems and limitations in describing alternative format materials based on the traditional MAchine Readable Cataloging (MARC) structure. To address these problems, this research proposes an XML-based descriptive metadata framework that establishes general but fundamental bibliographic aspects of various alternative format materials by providing core elements that are essential in describing these materials. Different from existing bibliographic structures, the proposed metadata framework can represent a fundamental descriptive structure by establishing four upper-level categories, 17 core elements, and 10 sub-elements in a hierarchical structure optimized to alternative format materials. By using this principal descriptive structure, the proposed metadata framework can guide different institutions in the creation of bibliographic records for these materials in a consistent way. It is also expected to address the difficulties in describing alternative format materials in library communities and enhance the information accessibility of individuals with various types of disabilities. In addition, the proposed metadata framework is an alternative approach which functions as a mediator between heterogeneous characteristics of alternative format materials and the existing bibliographic structures in library communities.

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.

The purposes of this study are to explore FRBR utilities such as work clustering and expression clustering and problems of application of the FRBR by developing work and expression clustering algorithm and implementing it into cataloging system, and to suggest new cataloging rules for FRBR and guideline of MARC description to improve FRBR work clustering. FRBR was suggested by necessitation of collocation function of bibliographic records according to increase of searching materials and multi-version materials, but FRBRization has some problems such as imperfect conversion of bibliographic records to FRBR records and inappropriateness of current cataloging rules for FRBR. Bibliographic records must be processed by FRBR algorithm to construct FRBRized system, but bibliographic records and current cataloging rules couldn't perfectly support FRBRization. Therefore cataloging rules and guidelines of MARC description for FRBR are needed. For constructing FRBRized cataloging system in Korea, it is needed to find problems and solution through FRBR practical application such as developing FRBR algorithm and applying it to cataloging records.

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.
