Discovery is an emerging concept to enhance the search capabilities of library resources with the Next Generation Library Catalog. This paper defined the Discovery feature based on the information search behavior, and then derived the elements that make up its function. After that, the 11 regional representatives libraries' OPACs and 3 Internet bookstores are evaluated and compared against Search & Discovery capabilities. As a result, the Internet bookstores were superior to the libraries' OPACs for all the elements that make up the Discovery functions. This study verified that the public libraries OPACs are still concentrating on known item search, and it is hard for the users to meet a serendipity which is gained through the Discovery functions.

Based on the comprehensive literature search and the sample library surveys, some observations are made on the impact of online information technologies for reference services. Various issues specifically with OPAC, CD-ROM, remote database access, and internet environment are overviewed as the source of and trigger for change in reference librarianship and in terms of expectations as well as difficulties. The paper then focuses on how these technologies influence on the roles of reference librarians as intermediaries in information providing, instructing, consulting, and evaluating functions. This leads to rethinking the conceptual basis of today's reference service and the competencies for reference librarians with new functions and responsibilities.

Needs for up-to-date research information in various academic and research organizations are rapidly increasing in our country. It requires that researchers utilize worldwide information networks such as Internet to obtain recent information. In this study, various information searching tools and services available on Internet are investigated and information resources, especially scholarly resources, are explored using WAIS, WWW. Gopher, and OPACs. These information resources are analyzed to evaluate the value of Internet as a research network.

The purpose of this study is to evaluate the quality of the Serials Union Catalog(UCAT) of KISTI. In examining both MARC records and bibliographic display records of 172 Japanese serials, AACR2R and KORMARC formats were used as the standard rules. Those records were described in the minimum or incomplete level ; but had repeated errors in various data fields, which included the incorrect choice of main headings, parallel titles and other titles, the improper use of language codes and related data fields, and the provision of incomplete information, etc. To improve the overall quality of bibliographic database, thorough comprehension and application of cataloging rules and MARC formats are strongly required.

Library and information science professionals have to grasp user's needs and make the best decisions when designing, acquiring, and managing library information systems. However, it is not easy for them to make the decision owing to the lack of an understanding of the characteristics of a specific user group in computer-based information systems in libraries. The aim of this study was to provide information on the characteristics and abilities of specific user groups such as male & female student groups, undergraduate & graduate ones, Sciences and Humanities majored ones etc. The actual OPAC systems were searched by specific student user groups in selected academic libraries in both Republic of Korea and the States for the purpose(Author, Title, and Subject search). Ouestionnaire was prepared and administered to Korean college students in the city of Taegu, Korea and adjacent area. Two hundred and seven usable questionnaires were obtained and analyzed. These were analyzed using descriptive, inferential statistics, and SPSS software. The major findings by data analysis of this study were described in chapters 4 and 5 of this paper in detail. Also, conclusions were drawn from the findings in this paper, and recommendations were proposed when designing, adopting, or managing a new system.

This research looked into both meaning and value of library catalog through the information behavior of user and suggested a plan to improve the quality and search functions, which are reflected the users' information needs and search behavior. U-CAT, a experimentally developed with reinforcing the contents and search functions of current library catalogs, was tested with the degree of satisfaction by the sample user group. The test results showed that the user's satisfaction on U-CAT was very high. The result verified that a little change with current library catalogs (to upgrade its quality) could result in a higher satisfaction of user group.

Catalogers have been reporting the ways they use the Internet for several years, but as yet there has been little evaluation done to determine for which areas of cataloging the Internet is a valuable tool and for which areas it is not as useful. A survey was conducted in an effort to elicit this information. The responses indicated four areas in which catalogers use the Internet : searching the OPACs of other libraries, communicating with colleagues, accessing online cataloging documentation and publications, and authority work. Some catalogers also related processes for which they have found the Internet to not be efficient.

This research is a case study that describes the NUCLIS21(Nuclear Information System 21), an integrated web-based information management system of KAERI(Korea Atomic Energy Research Institute), implemented to carry out the role of a national nuclear information center with government support as an information infra implementation programme. Through its user-centered single interface, the system aims at building an infrastructure for the national nuclear information center, as well as improving the information management system of the TID(Technical Information Department) within the institute. The system consists of two major parts which are an integrated module of the MIS and six different kinds of system. These include the Integral search system with OPAC, My Library, the Acquisition system, the Catalogue system, the Information Supply system, and the Serial Publication system. The DB is composed of Bibliographical DB, Original text DB and Abstract DB. A special feature of this system was designed as a unified network system through connection to MIS(Management Integration System) of the institute, so users can get research information for projects. Therefore, they have access to available information easily and access to the ongoing service of this system. Furthermore, users can share information by using our system. The survey has it that 75.7%(200 persons), 62.1%(164 persons) and 78.4%(207 persons) of the respondents are satisfied with the fidelity, speediness, and convenience of the system respectively, and the overall satisfaction of the respondents is comparably high.

The microphysics and spatio-temporal distribution of atmospheric aerosols are responsible for estimating the optical properties at a given location. Its accurate estimation is essential to plan efficient simulation for radiative transfer. For this sake, synergetic use of reanalysis data with optics database was used as a potential tool to precisely derive the aerosol model on the basis of the major representative particulates exist within a model grid. In detail, mixing of aerosol types weighted by aerosol optical depth (AOD) components has been developed. This synergetic aerosol model (SAM) is spectrally extended up to $40{\mu}m$. For the major aerosol event cases, SAM showed that the mixed aerosol particles were totally different from the typical standard aerosol models provided by the radiative transfer model. The correlation among the derived aerosol optical properties along with ground-based observation data has also been compared. The current results will help to improve the radiative transfer model simulation under the real atmospheric environment.

With a purpose of investigating the current status of resource organization for infants and young children's resources, this study examined 8 municipal libraries in J city and suggested recommendations for improvements. To do that, interviews were conducted with 8 children's librarians and 25 users, who were parents visiting the libraries. All libraries examined were using KDC to classify young children's resources, but books were shelved by the alphabetic order of publishers' names. This arrangement strategy was regarded very convenient in re-shelving materials from the perspective of librarians, but users had difficulties in finding books because of the separation of the classification system and the arrangement system. Also, the online public cataloging system did not provide accurate and sufficient information to locate a book. Based on the results, this study suggested two ways for improvements: (1) classifying and arranging books by KDC, (2) developing a new classification system customized to infants and young children.
