From 1990s the Ministry of Education and KERIS have developed nationwide academic resource sharing and service system based on universities, and have contributed to bridge the gap of information and to facilitate resource sharing between universities. Meanwhile, in Japan which starts 15 years earlier than us, the Ministry of Education and NII built nationwide academic resource sharing and service system with starting on the project of university holding resource sharing and until now have shown similar aspect of development like us. But lately, since information environment has been changing rapidly, Japan try to find new paradigm which goes around electronic resources management substitute for physical resources and open access based academic communication, institutional repository which disseminate university's research output to the outside world. This study compare academic resource sharing and service system between Japan and Korea and try to suggest for Korean academic resource sharing and service system development. In Korea, firstly we should try to replacing published resources management system to electronic resources', secondly, reorganizing oversea's resource sharing and service system, thirdly, reactivating institutional repository toward open access, finally, unification of distracted driving force.

Motivated by the open access movement, research institutions are building Institutional repositories for a nation-wide knowledge distribution infrastructure. IKIS (Institute Knowledge Inventory System) was proposed to integrate materials produced by government-sponsored 23 institutions of the economic, social and human fields, to contribute for policy-making in national agenda and to proffer services to a people. As IKIS project goes on. the project turns out to be slower than planned especially In terms of building up content and improving system functions. This study aims to investigate the methods for promoting the system in terms of management and system developments using multiple research methods such as surveys and interviews. Five issues including budgets and marketing are proposed for the management strategies, whereas three ones Including content and system performance improvements are suggested for the system development. The study results can be utilized as guidelines for managing university and school repositories as well as IKIS.

Interlibrary loan has been a very common library service in the developed countries but it is yet to be actualized formerly in Korea. As Korea is moving toward an information society where all the individual user's request in the library should be met, we need to understand, in detail, the theory and practice of interlibrary loan service. As various information technology has been applied to the libraries, the libraries became the open system. Thus, the libraries become more cooperative, form networks, and make interlibrary loan service available. This study is based on the following three hypothesis formulated from the systems theory. 1. If libraries cooperate each other and form some kind of networks by mail, computers or telecommunications, they become the open system. 2. If a library develops as the open system, interlibrary loan becomes available in the library. 3. If the interlibrary loan system works, the role of the librarians will be changed. The research was carried out by analyzing the various studies about interlibrary loan service and by examining the interlibrary loan systerns presently working in the U.S.. The conclusions are reached deductively from the data. Some of the terminology used are defined as follows: System: a network of interrelated procedures that are joined together to perform an activity or to accomplish a specific objective. It is, in effect, all the ingredient which make up the whole. Cooperation: Working together to benefit participant libraries. Network: a much more structured type of cooperation in which definite regions or areas are connected by electronic or other means to promote interlibrary loaning of materials, in-service traing & other sharing of resources. Interlibrary loan: the lending of books between libraries. The model of cooperation or networks was used to be (1) a star type, (2) a hieranchical type, (3) a distributed type or (4) the combination of aforementioned three. However, the development of the telecommunications and computers enables all kinds of libraires cooperate together. Interlibrary loan service starts with the needs of user's information. The information have to be logically accessed through bibliographies, computers, electronic mails and satellite communications. And the logical access requires the information technology and the libraries become cooperative. The physical access to the information follows next but only traditional method of mail and some commercial service are currently available for this purpose. Therefore, researches are needed to develop this physical access. If the libraries form networks, the microaspect of library changes accordingly as the macroaspect changes. If the libraries . cooperate to become one large world library, the librarians plan, organize, control library operations and report the results. And the librarians work inside and outside of the library to cooperate with other libraries. Only the cooperation of the libraries will enhance interlibrary loan and the Korean librarians have to be prepared to accept the new role of librarianship for the interlibrary loan service.

Slicing Radio Access Network (RAN) can help in effectively utilizing the network bandwidth and to better manage the increasing traffic over interent. RAN slicing system discussed in this paper is based on an open-source slicing mechanism in which we write a JSON configuration file for slicing policy and send it to the FlexRAN controller. FlexRAN controlls the core networks (CNs) through OAI-RAN on the evolved packet core (EPC) component of this system. Each CN is responsible for handling a saperate RAN slice. The type of internet traffic is identified by the FlexRAN crontroller and is sent to the respective CN through OAI-RAN. CN handles the traffic according to the allocated bandwidth and in this way the internet traffic is sliced inside the EPC component.

This study aims to propose management plans for 'Archive Village' that are operating in order to protect important private records and archives. Since 2008, Archive Villages from National Archives of Korea have had nearly 3,000 more records by 2014. However, many users have had difficulties to know the status of the recorded material, even less access to record's informations. This problem arising is that it is difficult to manage and use records. The purpose of this study is to propose a plan for the management of records, which is to realize the 'Computerization of records' official opinion, one of which was raised in the previous study. Because the project is facing the issue of 'human resources and costs', 'the burden of system construction'. This study is implemented records management system considering the problems noted above, utilizing AtoM (Access to Memory).

The ultimate goal of preserving and maintaining the records is to use them practically. The effective use of records should be supported by the reasonable recordskeeping systems and access standards. In this report, I examined the Korean laws and administrative systems related to the public records access issues. After I pointed out major problems of the access laws, the Government Information Opening Act (GOIA), and the problems in practices, I suggested some alternatives for the betterment of the access system. The GIOA established "eight standards of exemption to access" not to open some information to protect national interests and privacy. The Public Records Management Act (PRMA) applies to the archives transferred to "professional archives." The two laws show fundamental differences in the ways to open the public records to public. First, the GIOA deals with the whole information (the records) that public institutions keep and maintain, while the PRMA deals with the records that were transferred to the Government Archives. Second, the GIOA provides with a legal procedure to open public records and the standards to open or not to open them, while the PRMA allows the Government Archives to decide whether the transferred records should be opened or not. Third, the GIOA applies to record producing agencies, while the PRMA applies to public archival institutions. One of the most critical inadequacies of the PRMA is that there are no standards to judge to open the archives through reclassification procedure. The GIOA also suggests only the type of information that is not accessible. It does not specify how long the records can be closed. The GARS does not include the records less than 30 years old as its objects of the reclassification. To facilitate the opening of the archives, we need to revise the GIOA and the PRMA. It is necessary to clearly divide the realms between the GIOA and the PRMA on the access of the archives. The PRMA should clarify the principles of the reclassification as well as reclassifying method and exceptions. The exemption standards of the GIOA should be revised to restrict the abuse of the exemption clauses, and they should not be applied to the archives in the GARS indiscreetly and unconditionally.

High-resolution satellite image processing software should be able to ensure accurate, fast, compact data processing in offline or online environment. In this paper, component software for high-resolution satellite image processing is developed using OpenGIS components and real-time data processing architecture. The developed component software is composed of three major packages, which are data provide package, user interface package, and fast data processing package. The data provider package encodes and decodes diverse image/vector data formats and give identical data access methods to developers. The user interface package supports menus, toolbars, dialogs, and events to use easier. The fast data processing package follows the OpenGIS's data processing standards, which can deal with several processors as components with standard procedural functionalities.
