One of the fundamental roles of libraries is to provide users with efficient and easy retrieval of materials. Various discussions have been made at domestic and abroad to improve the accessibility of materials by category, user, and collection, and at the center of this is the issue of improving classification and cataloging systems. However, there are few studies in this area dealing with the data accessibility of the DLS catalog, which is a central tool for accessing domestic school library materials. This study started from the appeal of school library users to the difficulty of searching and accessing books, especially literature. This study is an exploratory study that attempts to derive problems by finding the causes of there difficulties from various aspects. To this study, we surveyed and analyzed the current status of school library collections, the data registration of the school library support system DLS, the subject accessibility of catalog records produced through this, and the recognition and opinions of school library professionals. As a result, school library collections were highly concentrated in the literature field, and it was found that there was not enough catalog bibliographic records to provide efficient access to these collections. In addition, it was found to be somewhat lacking through the DLS search function to compensate for this. Surveys of school librarians and librarians have also identified this problem, and a rich topic index and search keyword assignments have been drawn to the majority of opinions as a way to improve access to materials in school library catalogs. As a continuous discussion on this subject, the plan for improving access to school library materials will be more concrete through future user studies and new challenges for bookshelf classification.

The purpose of this study is to identify users behavioral characteristics for using the online catalog opened in May 1996 at Duksung Women's University Library. 278 student users were surveyed from October 4th to 8th in 1996. Major findings are as follows. 1. Most users$(87.4\%)$ prefer the online catalog to the card catalog and regard the online catalog easy to use$(89.6\%)$ 2. $(65.8\%)$ of users are active users who frequently use the online catalog at least 10 times or more per semester. 3. $10.4\%$ of users feel the online catalog difficult because they do not know how to use it. 4. Most users prefer the menu search mode among menu, command and fill-in-blank search modes offered by DISCOVER. The most preferred access points are the title for known-item search and subject headings for subject search. 5. User's attitude toward the online catalog is very favorable$(83.5\%)$, however, the search success rate is rather low $(77.0\%)$ compared to that of the card catalog $(87.0\%)$ 6. The title and author are regarded easy to use among access points offered by DISCOVER. Classification numbers and call numbers are the least easy access points to use. 7. Since users show lack of knowledge of how to use the online catalog, education and training programs on the online catalog use for users are needed. 8. Users showed different search patterns for pursuing different search goals. The most preferred access points are the title for known-item search and subject headings for subject search. These search behaviors are different from those in using the card for both the known-item search and subject search was the title.

The purpose of this study is to improve the faceted navigation function of next-generation library catalogs(NGC) using the tables in a classification scheme. Because the tables provide forms or contents of materials systematically, faceted navigation based on the tables can be as effective as faceted navigation based on language, publishing date, or class-level subject facet. Therefore, class numbers based on the Korean Decimal Classification (KDC) were examined and the characteristics of schedules and tables were analyzed. As a result, suggestions to improve faceted navigation was provided. Moreover, the method using the tables does not need additional resources to derive facets because the facet analysis process is always carried out in the classification process.

The revision of the Korean Cataloging Rules (KCR) is in progress in order to conform IFLA LRM conceptual model and to strengthen its internal stability. Religious works, along with musical works and legal works, have been treated as special and important in cataloging rules. This trend continues in the new cataloging rules that seek a bibliographic model that interconnects related materials. However since KCR2(1966), there are no rules for access points or specific rules on religious works. Under the circumstances, this study analyzed (1) the contents of religious works in the recently revised cataloging rules, (2) the access points and their functions for religious works implemented in online catalogs and authority system, and finally (3) the direction and scope of KCR revision. As a result of the study, this study suggested that it is necessary to prepare detailed rules for preferred title and authorized access points for various religious works in KCR. In conclusion, some issues for further discussion were summarized.

인터넷 사용자의 증가로 인한 서버의 과부하 및 네트워크 응답시간 지연의 대안으로 캐시서버의 사용이 보편화되고 있다. 그러 나, 최근 유해사이트의 급격한 중가로 캐시 서버의 부가 기능인 ACL(Access Control List)또한 중요한 기능의 하나가 되면서 대량의 유해사이트 차단 목록이 캐시 서버의 병목현상을 가중시키고 있다 본 논문에서는 캐시 서버의 대명사격인 Squid의 ACL방식과 대량의 black list를 적용했을 때의 ACL의 regular expression방식의 문제점을 살펴보고, 대량의 black list에 적합한 hash기반 ACL 처리 방식을 제안한다. hash를 이용한 ACL방식은 빠른 검색을 제공하여 캐시 서버의 응답시간에 큰 영향을 주지않기 때문에 캐시서버가 정상적인 서비스를 할 수 있도록 해준다.

Real-Time Linux는 기존의 Linux에 실시간 기능을 추가한 것으로서, 태스크 스케줄링 방법은 우선순위 기반의 스케줄링 방법을 사용한다. 그러나, 태스크의 개수가 많아지면 가장 높은 우선순위의 태스크를 찾는데 걸리는 시간이 태스크 개수에 비례해서 많이 걸린다. 이러한 이유로 태스크의 개수가 제한적일 수밖에 없다. 본 논문에서는 우선순위별로 서로 다른 목록을 유지하고, Bit Masking 기법을 사용함으로써 가장 높은 우선순위 태스크를 선택하는데 걸리는 시간을 상수시간으로 줄이고 각 태스크들의 시그널을 처리하는 부분을 좀더 효율적으로 처리하도록 함으로써 Real-Time Linux의 실시간 스케줄링 기능을 개선하였다.

Currently, most academic libraries provide OPAC 2.0 service which applies Web 2.0 based-internet search engine to OPAC. The new service is for the users' convenience and so the considerations for the users' opinions are of great importance for each of services. The objectives of the study were to investigate perceptions of the students as the main user for academic library on the importance for the main services of OPAC 2.0 and analyzed information sources and the reasons for book search by the virtue of this service. The study showed that there were the users' high expectations on accuracy and satisfaction for OPAC 2.0, and the main searching information source was the OPAC of the universities to which the users belong due to familiar screen as well as convenient reading and book loan through it. The OPAC 2.0 service needs to be improved with the consideration of the users' opinions.

This study attempts to investigate the current practice of electronic resources in the academic libraries and to explore the changes of paradigm in the organization of information. It reviewed how academic libraries have acquired and organized electronic resources. It also investigated the library home pages of 30 academic libraries in order to identify the category of electronic resources, metadata, and linkage methods with various material types such as printed resources and theses. To perform extended functions of library catalogs, it is essential for academic libraries to manage the metadata of various resources together and provide enhanced access and linkage of related resources.

This study explores the importance of OSI standards in library environment and specifically of Z39.50/SR information retrival protocols and ILL protocol. Libraries and other information systems need to implement these ap lication protocols in order to facilitate the sharing of library information resources through information networks. The foreign systems which have implemented the standard protocols are reviewed in this paper, and it is suggested that search results of OPACs and other bibliographic databases be directly used for electronic document request for fast document delivery, first by implementing Z39.50 OPACs and standard interlibrary loan systems and next by integrating the two systems in Korean electronic libraries.
