This paper is to probe foreign cases about risk management and to develop a method for the risk management of the digital resources, This is under the perception that the risk management is necessary for digital archiving implementation. OCLC and Cornell University Library are the leading institutions in the area of risk management. They are the best examples because they make a decision about the risk management through the testing and experimentation. Based on case studies, identification of element of risk management process in our environment, the foundation of national center for risk management, and testing file format and migration program as practical plan of risk management for digital resources are suggested.

Digital library in knowledge-information-based society of the 21st century should develop legally various digital information resources in order to provide information services to users. This study analyzes and examines in detail the related provisions of copyright law relating to the development of digital information resources(digitalized works, electronic books, electronic journals, electronic reserve materials etc.). This study also points out the problems of the current Copyright Act and proposed Copyright Act of Korea. And it suggests necessary measures and improved plans to promote the development of digital information resources.

This paper reviews digital collection development policies of academic libraries in America which attempted to digitize their collections in order to preserve their analog collections and to provide easy access to their digital collections. Such factors as selecting materials for digitization, sustainable size of digital collection, bibliographic control and collection management, coordinated digital collection project are discussed in order to be fully integrated into traditional collection development policies of academic libraries.

The current technological revolution pushes forward the innovation in the library information systems. This study proposes functional requirements and an architectural reference model of Semantic Library, recognized as a prototype of next-generation library information systems, that is a seamless convergence of the library information systems and the Internet technologies. Semantic Library can realize semantic interoperability and integration based on ontology and metadata, and also renovate information services for users with openness, sharing, participation and collaboration. Semantic Library will be effectively implemented by means of service-oriented architecture and the logical structure of FRBR. In this study, a reference model of Semantic Library consisting of 6 horizontal layers and 3 vertical elements is presented as a next-generation model of library information systems.

This study examined the perceptions of freshmen students on the use of a university library site. The students were in the beginning month of their undergraduate program in Hansung University without being taught a formal library instruction session. The results show users experienced uncertainty, difficultly, confusion and anxiety while they were interacting with various functions of the library site. The findings revealed that the users' perceptions were originated from: (1) the insufficiency of the students' knowledge and skills related to library use and (2) the inadequacy of the library system features, in particular its interface features. Based on the findings, implications to improve library instructional services and system interfaces are suggested.

This study measures library anxiety using K-LAS for senior users, who constitute the smallest part of a public library users group. According to the findings, the overall score of library anxiety was 2.95, which was higher than the score of university students and local residents measured in previous studies. It was analyzed that the anxiety score of 'Digital Information' factor was the highest. In addition, it was found that the anxiety score was high in the old age group and the low education level group. Senior users whose intention of visit was to attend a community class and frequency of visit was lower showed higher library anxiety. This study suggests a method to reduce library anxiety of senior users, based on the analysis findings.

Despite of many researches related to create 3D digital maps, it is still time-consuming and costly because a large part of 3D digital mapping is conducted manually. To circumvent this limitation, we proposed methodologies to create 3D digital maps with 3D symbols automatically. For this purpose, firstly, the 3D symbol library to represent 3D objects as 3D symbols was constructed. In this library, we stored the attribute and geometry information of 3D objects which define types and shapes of symbols respectively. These information were used to match 3D objects with 3D symbols and extracted from 2D digital maps and LiDAR(Light Detection and Ranging) data. Then, to locate 3D symbols into a base map automatically, we used predefined parameters such as the size, the height, the rotation angle and the center of gravity of 3D objects which are extracted from LiDAR data. Finally, the 3D digital map in urban area was constructed and the results were tested. Through this research, we can identify that the developed algorithms can be used as effective techniques for 3D digital mapping.

This study suggested a scheme of revitalization and development of digital talking books(DTB) for the print disable people. In Korea, the number of print disabled people is quickly increasing because of increasing of the acquired blind and the elderly in population. To promote information service and to encourage active participation from the group categorized as print disabled people, library is required two distinctive considerations, design and implementation of authoring tool for DTB and policy and administrative consideration for revitalization for DTB service to the print disable people.

In this study, co-word occurrence analysis was performed on 288 articles rerieved from the Web of Science DB with the topic of web archiving. Results showed that research on image archiving information technology and system were most frequently carried out especially in medical area. Within library and information science and records management & archives areas, web archiving/digital preservation project subject and web archiving tools and methodology subject were studied mostly. It is expected that research related to web archiving software and tools will be increased in near future.

Digital library is the most important database system that needs information retrieval engine for natural language documents and multimedia data. This paper describes the experimental results of information retrieval engine and browser based on natural language processing. It includes lexical analysis, syntax processing, stemming, and keyword indexing for the natural language text. With the experimental database ‘Earth and Space Science’ that has lots of images and titles and their descriptive text in natural language, text-based search engine was tested. Combined with content-based image search engine, it is expected to be a multimedia information retrieval system in digital library
