The goal of this paper is mainly to review and summarize the multimedia information formats and technical standards that have been applied so that library and information specialists can understand them systematically. The most fundamental differences between digital library and the classic one are specified by describing the general characteristics of hypermedia information environment. With the proprietary advantages of multimedia technology to digital library developments, the core technological standards (publicly available) of text and non-text data, including multimedia data, are reviewed. Finally, it describes some important and professional perspectives and roles of library practioners as well as researchers who are engaged with the innovation of digital library.

This study intends to implement a OPAC prototype for digital kids. To the end, this study applies prototyping techniques that design, evaluate and improve an early sample model. Included in this study are as follows: (1) design a conceptual model of new OPACs based on the information need analysis of digital kids, (2) implement a OPAC prototype with WordPress 4.2 version, (3) evaluate the prototype OPAC from the viewpoint of digital kids and children librarians, and finally, (4) suggest the improved model and implementational strategies for kid's OPAC. 6 fourth and fifth graders in the elementary school and 5 children librarians in public libraries participate in the final evaluation process.

The major role of school librarians in Korea has been providing reading guidance and library user education with paper resources. However, digital users have become more ubiquitous and demand more information with the images and digital materials. Therefore, school libraries need to collect more images and digital materials. At the same time, school librarians have to equip themselves with the ability to cope with this transformation. The qualified school librarians not only should have a teaching certificate but also know about techniques to transform various library materials into digital formats. Teachers and students could use these materials for their Web site homepages and Powerpoint presentations.

In this digital environment, license contracting and technical protection measure are being used by copyright holders as a means to restrict the rights of information users. The study reviewed the conflicting relationship between the copyright law and the contract law for digital resources the use of which is based on license contracting, and investigated the legal interpretations of the conflicting relationship between the two. And then based on the analysis of IF LA's position on copyright in the digital environment, the study suggested the expected role of librarians to cope with the technological overrides of copyright rules and to expand the rights of information users.

This paper aims to seek ways of optimizing the operations of Collaborative Digital Reference Service(CDRS) in Korea. CDRS tries to specialize the reference service through world-wide collaborative service. In this study seven international CDRS services including "QuestionPoint" operated by ALA and one national service, "Ask a Librarian" by the National Library of Korea were surveyed. A focused analysis of CDRS in Korea shows not only a sharp increase in use by the public, but also much application in research and academic activities by university students and workers.

This article reviews the current infrastructure of multi-media network which has significant implications to digital library development and the networked information service. Network information service which is based on the digital technology has become quite popular in recent post-Web environment. But it is not easy and simple to develope digital library system with the rapid media innovation and digital network technology The existed multimedia network infrastructure need to be observed precisely and discussed critically in the context of economy and policy development for digital library service.

Many of the development countries in the world have been investing a lot of money and developing plans for a national digital library in order to .:em the information power in the 21st century. In order for our country to compete with others, it is also urgent to build a National Digital Library in Korea, which can provide a variety of multimedia information for the people. In this study, based on the investigation of the several cases of the national digital libraries in the developed countries, we suggest a detailed plan for the National Digital Library which includes building, facilities, equipments, organization, staff, events, frictions, and expected budget.

The change in information technology demands drastic change in digital library service. This study defines what a social semantic digital library should consist of and proposes a new architecture that incorporates core functions needed in designing a SSDL. The SSDL supports semantic information processing based on metadata and ontology and is an innovation system that allows SSDL users to participate in generating new knowledge by interacting with existing metadata and ontology structures. This study designed a SSDL model that consists of five horizontal and two vertical structures.

Currently, 54 kinds of digital maps are provided by National Geographic Information Clearinghouse and the majority of those maps are based on aerial photographs or satellite image. The digital maps which symbolize and simplifies the topography and objects from ortho-photos does not reflect the objects 'shapes and facilities' changes. Especially, underground structures and complex building shapes are not correctly identifies by ortho-photos. Furthermore, the 1/1,000 and 1/500-1/2,500 maps for urban area produced by some local government or public organizations have detailed information with high precision, it is not easy to update the information due to the frequent changes of structures in the city. Although some efforts to solve this problem such as conducting field survey and shorten the survey period were tried, it is not the fundamental solution due to the high cost. Therefore, in this study, a realtime renewal and update of digital map using general survey are suggested. By assigning absolute coordinates to the general survey products and matching with digital maps, it is possible to update the digital map economically and rapidly. In addition, it is suggested that the construction of DB for general survey and sharing among survey companies to solve the duplicated survey.

Latest digital cinema is getting more interest on recent days. The combination of visually immersive 3D movie with chair movements and other physical effects has added more enjoyment. The movement of the chair is controlled manually in these digital cinemas. By the analysis of the digital cinema's video sequences, movement of the chair can be controlled automatically. In the proposed method first of all the motion of focused object and the background is identified and then the motion vector information is extracted by using the 9-search range. The motion vector is determined only for the movement of background while the object is stationary. The extracted Motion information from the digital cinemas is used for the movement control of the chair. The experimental results show that the proposed method outperforms the existing methods in terms of accuracy.
