TETRA system provides the radio authentication service which permits only authorized radio to access network. Radio authentication is the process which checks the sameness of authentication-key(K) shared between radio and authentication center by challenge-response protocol. TETRA standard authentication protocol can prevent the clone radio to copy ISSI from accessing network, but can't prevent the clone radio to copy ISSI & authentication-key. This paper analyzes authentication-key generation/delivery/infection model in TETRA authentication system and analyzes the threat of clone radio caused by authentication-key exposure. Finally we propose the new authentication protocol which prevent the clone radio to copy ISSI & authentication-key from accessing network.

With China Market and strengthening of an international and political position of China, we need to promote exchange and cooperation with China for the supplement of economic vitality and for contriving the contribution of the flow of growth. The necessity of salient traits is needed such as sharing information, training a specialist, network between China Specialists, system establishment of China information DB and sharing China information. Accordingly, KIEP makes the most of limited special manpower and information, and developed China Specialist Forum Website : CSF which will make a stepping stone of systematic, synthetic exchange and cooperation with China. KIEP presented a development direction, comparing and analyzing promptly easy to get the information China Specialists want here, CSF made for mutual exchange of science, trade and the other issue, Taiwan website "a commercial business intelligence network of China and Taiwan", and Singapore "IE Singapore".

There has been significant progress in the method of digital information sharing in recent years. To take advantage of the benefits of XML, OGC developed GML, which is the application of XML in the field of GIS, and released web service Implementation specification for offering GML services. Through the use of GML, therefore, it is possible to expand the methods of sharing geographical information through the Web. This study aims to develop a method to apply GML to improve the geographic information sharing services. GML can be used to effectively offer data in real time so that the currentness of the data can be maintained. This study analysed the architecture of the National Geographic Information Clearinghouse and developed a GML specification and web services that can be used within the existing architecture to expand the services. Based on the specification, this study constructed a prototype system to proved the concept.

The new technology, RSS(Really Simple Syndication), allows people to send and receive a lot of up-to-date information by constant monitoring websites and databases for new information, without having to visit the site or database. The "gatekeeping" task for capturing and delivering various information influx via new digital channels as speedy as possible, is being discussed as a new form of service in the field of information service system nowadays. Given this situation, the RSS tool can be greatly useful in the gatekeeping task. This paper, by analyzing concrete cases in which RSS is actually employed in libraries and also newly applied to other diverse information services in France, expects to provide insightful ideas for developing innovative information services in other countries.

This study aims at developing a policy framework for a digital curation based on the access, co-ownership, reuse, and long-term preservation of digital information resources. To accomplish this, our study analysed a similar policy and support services of a main UK research institution and the DCC. It selected the main stages of the DCC lifecycle and developed a policy framework accordingly. Such a framework could serve as the basis for both state and individual institutions, and for developing standards and guidelines for a digital curation of digital information resources.

한국과학기술정보원(KISTI) 바이오인포매틱스센터(CCBB)에서는 생명과학 관련 주제별 Open Archiving Community의 구성과 운영을 통한 연구자들 간의 정보교환을 유도하고, 더불어 논문뿐만 아니라 세미나, 연구노트 등의 최신의 연구 정보를 공유할 수 있도록 생명과학 Open Archiving Community 시스템을 구축하여 운영하려고 한다. 본 community에서 수집, 구축, 서비스할 점보의 종류는 아티클, 학위논문 연구보고서, 발표자료, 연구노트, 실험데이터, 전자자료 등이다. 그러므로, 전 세계적으로 많이 활용되고 있는 Dublin-core, Marc21, MODS를 비교 분석하여 MODS 메타데이터를 기준으로 아티클과 같은 문헌정보 뿐만 아니라 실험결과, 연구노트 등의 비문헌정보도 유연성 있게 적용할 수 있는 생명과학 관련 주제별 Open Archiving Community를 위한 메타데이터 스키마를 설계하였다.

온라인 커뮤니티는 사용자들의 상호작용을 기반으로 생성된 컨텐츠(member-generated content)를 그 핵심가치로 제시하고 있으며, 이용자들은 소통의 장으로써 온라인 커뮤니티 내에서 정보획득, 교육자료 공유 등 다양한 혜택을 누릴 수 있다. 최근 2년 페이스북과 카카오스토리, 밴드 등과 같은 대표적인 소셜 네트워크 서비스(SNS) 이용자 수가 감소한 반면, 온라인 커뮤니티만 상승세를 보이고 있다. 따라서 본 연구에서는 여자고등학생들을 대상으로 고등학생들의 온라인커뮤니티 이용 실태와 이용하는 의도를 살펴보고자 한다. 연구를 위해 정보품질, 커뮤니티 정보의 신뢰성, 학습 혜택, 사회적 혜택, 자아존중감 혜택, 쾌락적 혜택, 경제적 혜택, 신뢰, 몰입 그리고 지속사용의도와 관련된 설문을 실시하였다.

본 연구는 청소년들의 SNS 이용동기와 이용실태를 알아보고자 하였다. 연구를 위해 부산에 살고 있는 고등학생들을 대상으로 조사를 실시하였으며, 사회적 동기, 유희적 동기, 기능적 동기, 심리적 동기, 정보공유, 탈출욕구, 교우실현, 전문적 혜택 등에 대한 설문문항을 토대로 설문조사를 진행하였다. 설문 결과, 대부분의 학생들이 페이스북을 사용하고 있었으며, 그 다음으로 인스타그램을 많이 이용하는 것으로 나타났다. 그리고 청소년들은 기능적 동기와 유희적 동기와 교유관계 유지를 위한 동기 때문에 SNS를 이용하고 있는 것으로 나타났다. 현재 청소년들이 SNS를 활발히 활용하고 있고 왜 이용하고 있는지에 대한 동기를 파악하여 청소년들의 심리상태를 점검해 볼 수 있다는 차원에서 연구의 의의가 있다고 볼 수 있다.
