This paper is a comparative study of feature selection methods for Korean web documents clustering. First, we focused on how the term feature and the co-link of web documents affect clustering performance. We clustered web documents by native term feature, co-link and both, and compared the output results with the originally allocated category. And we selected term features for each category using X2, Information Gain (IG), and Mutual Information (MI) from training documents, and applied these features to other experimental documents. In addition we suggested a new method named Max Feature Selection, which selects terms that have the maximum count for a category in each experimental document, and applied X2 (or MI or IG) values to each term instead of term frequency of documents, and clustered them. In the results, X2 shows a better performance than IG or MI, but the difference appears to be slight. But when we applied the Max Feature Selection Method, the clustering performance improved notably. Max Feature Selection is a simple but effective means of feature space reduction and shows powerful performance for Korean web document clustering.
In the era of knowledge and information society, specialists with a specific concentration are more appreciated than broad knowledge. Therefore, it is a growing trend that universities and departments restructure their vision and plans to foster specialized professionals. While responding to the needs of working libraries and adhering to the basic educational goals, the programs of the library and information science sector should be flexible to the external changes. In this sense, each university should develop customized curriculum based on its related policies, resources, and surrounding circumstances, with an emphasis on specialization over standardization. This paper discusses how to build specialized education programs in line with specific environments that each university is surrounded with, and by doing so, raise information professionals with specialized concentrations.

본 논문은 일본사회의 어린이 독서운동의 핵심인 문고운동을 고찰하고, 그것이 학교도서관에 미친 영향을 중점적으로 분석하였다. 어린이 독서운동과 학교도서관의 관계를 조사하기 위하여 두 가지 내용을 연구하였다. 하나는 일본의 정부가 주도하는 학교도서관, 어린이 독서활동과 관련된 정책이고 다른 하나는 시민이 주도한 190년대에는 학교도서관 활성화 운동에 참가하였다. 이 두 내용은 학교도서관을 교수-학습센터로서 보다 주로 어린이의 독서환경으로 강조하고 있다는 점에서 서로 밀접하게 관련되어 있다. 학교도서관을 독서시설로 이해하는 경향은 교과과정의 전개를 지원한다는 학교도서관 전문성의 확립을 저해하고 있다.
This paper investigates the Bunko, the center of Japanese child ren's reading movement, and its consisted by two parts; one subject is the programs and the law made by government which is related to either the school library or children's reading, the other is Bunko movements initiated by c itizen mostly mothers who wish to improve their children's reading ts started in 1960's and motivate the establishment of public libraries in 1970's, and it has tri ggered activating the school library after early 1990's. By analyzing the relationships of the two subject s it can be concluded that they are tightly connected each other by emphasizing the function of sch teaching-learning center but as a reading facility. It makes di fficult for the Japanese school library to establish the most important function of supporting curricul um.

It will review the ma in projects about them in order to portray what the future libraries will be like and how they can be developed. In particular, the eLib University and Penn State University, and the ubiquitous library projects in Carnegie Mel on University and Maryland University will be surveyed, through which the characteristics of the information services being operated by the ubiquitous libraries will be scanned.
The purpose of this study is to redefine the concept and scope of universal service and to develop universal service policy of South Korea for Korean reunification. The basic assumption of this study is that well developed universal service may contribute to the eventual reunification by ensuring equal access to information resources for the two peoples. The theoretical foundation of this study includes social capital and diffusion of innovations theory. This study uses policy analysis as both data collection and data analysis, more specifically qualitative policy analysis with triangulation for improving credibility. Data for the analysis were collected through legislation, other policy documents, and major agreements between North and South Korea related to informatization and unification. This study, identified the major characteristics of universal service and explored the current universal service in South Korea by analyzing major policy instruments of South Korea. In addition, this study presented a great possibility of cooperating in telecommunication policy and telecommunication infrastructure. Consequently, this study proposed policy recommendations in five areas: 1) redefining the scope of universal service, 2) developing a unified telecommunication infrastructure, 3) developing policy instruments, 4) restructuring government organizations, and 5) creating a participatory universal service model for Korean reunification.
The purpose of this study is to present a curricular model of information literacy at a national level to build a foundation for information literacy education that has not yet been systematically established in the Korean education system.
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.
본 연구는 서울 지역에 소재하고 있는 21개 공공도서관을 대상으로 DEA방법론을 사용하여 정보서비스 활동의 효율적 운영에 초점을 맞춰 상대적 효율성을 평가하였다. 정보서비스 활동의 평가를 위해 필요한 데이터는 202년 관측치를 사용하였으며, 투입요소로는 장서수, 연속간행물수 그리고 연간증가책수가 사용되었으며, 산출물로는 도서관이 효율적인 도서관이 되기 위해서는 현재 수준의 산출물 생산을 기준으로 현재 투입물의 29%를 감축해야 한다는 것을 의미한다. 그리고 비효율적인 도서관은 산출물의 과소생산보다는 투입물의 과다사용에 비효율의 원인이 있는 것으로 나타났으며, 특히 장서수의 운영이 가장 비효율적인 요소로 평가되었다. DEA방법론에 의한 평가 결과는 투입요소와 산출물의 수 또는 정의가 달라지면 다른 결과를 보여줄 수 있으므로 절대적인 것은 아니다.
This paper asesses the relative efficiency of public library s ervices by examining the relationship between library inputs and library outputs in library systems. Using Data Envelopment Analysis, this study derives efficiency scores in the provision of librar Seoul. The data are survey observa tions for 2002. We employ tot al holdings, total serials, and total acquisitions as inputs, and total circulations and reader visit s as outputs. The result shows that the could be reduced by one-three without sacrificing output if all libraries were as efficient as the be nchmark 4 identified by DEA. Too many total collections are the main source of inefficiency.

This study aims to examine and analyze the operations and activities of Friends of Libraries groups in foreign countries. Friends of Libraries are groups of people who are voluntarily associated in order to assist libraries in their work. They have been involved with various libraries in many countries for almost a century. They support libraries by raising funds, working as volunteers, performing P.R. activities, operating political campaigns and being involved in the community. Nowadays, Friends groups are considered more important than at any time in their history because they provide such diverse support. Thus, new groups are being established in many countries. This study suggests that the establishment of Friends groups could improve library operations and services in Korea.
이야기 들려주기는 예술의 한 분야로서 글을 모르는 취학 전 어린이에게 취학 준비과정으로 매우 효과적인 방만 그 효과는 크다고 할 수 없다. 이는 무엇보다도 프로그램 자체에 대한 인식이 부족하고 아울러 체계적으로 프로그램을 운영하고 있지 못하고 있기 때문이다. 따라서 본 연구의 목적은 오래 전부터 이야기 들려주기 프로그램을 운영하고 있는 미국 공공도서관의 실태를 조사, 검토하여 한국 공공도서관의 프로그램 운영 실태와 비교한 후 이야기 들려주기의 네 가지 구성 요소인 프로그램, 어린이 사서, 취학 전 어린이 및 도서관 환경에 초점을 맞춰 한국 공공도서관 실정에 맞는 효율적인 프로그램 운영 방안을 제시하는 데에 있다.
