이동 단말기, 무선인터넷 기술, 센서 기술의 발달로 인한 유비쿼터스 환경의 등장은 사용자의 위치에 상관없이 자유롭게 네트워크에 접속하여 다양한 서비스 이용과 정보 공유를 가능하게 하였다. 따라서 원할한 정보 공유와 서비스 이용을 위해서는 사용자에 대한 정보 보호 기술이 요구되어 진다. 또한 이런 유비쿼터스 환경에서의 프라이버시 정보는 개인의 동의 없이도 노출될 수 있으며, 제 3자에 의해 공유되거나 또는 악용적으로도 이용될 수 있다. 이에 본 논문에서는 유비쿼터스 환경 내에서 사용자의 프라이버시를 보장하기 위해 사용자에게 프라이버시 정보에 대한 배타적인 통제권을 부여함으로써 사용자 편의성이 제공되는 개인에 의한 RBAC 기반의 접근 제어 프레임워크를 제안한다.

To bridge digital divide, the nation's information services should be focused their attentions on people with disabilities. According to this philosophy, the public library's services for people with disabilities should be main streamed into its regular services. Providing equitable access for people with disabilities to public library's resources, facilities, and services, the standard library services policy or guideline should be developed as soon as possible. A draft in this papers may be helpful to a policy maker for public library services for people with disabilities

The increased concern about national security in the U.S. after the 9/11 terrorist attacks has influenced public rights of access to government information and its legal foundation, the Freedom of Information Act (FOIA). Public access to government information has been restricted at the policy level by a series of legislative and executive changes in FOIA after September 11, 2001, but the examination of statistics on FOIA implementation between fiscal years 1999 and 2004 shows that the strengthened national security measures did not have a considerable impact at the implementation level during this period. These contrasting findings might be due to the public officials' informal reaction to the criticism of the restriction on public access, bureaucratic inertia, and the use of new record categories not subject to FOIA.

Many visually handicapped people face difficulties with using libraries. Public libraries are thus required to meet the need of visually handicapped people. Public libraries should guarantee the visually handicapped the right to use appropriate services. If so, the visually handicapped can improve their life quality by decreasing information gap and increasing information comprehension or accessibility. This study is designed to analyze how visually handicapped people can use public libraries. Based on the analysis, this study can provide actual suggestions to improve opportunities for the visually handicapped to use libraries. Data are collected from visually handicapped people who are the members of Suseong Public Library, Daegu, Korea. In specific, this study can analyze various characteristics(i.e., information needs, selection and use behavior of information sources, difficulties and gaps to access information, use behavior and service satisfaction of public library) regarding their library use by telephone interviews.

본 논문에서는 HTPC를 제어하기 위한 제스처 기반의 인터페이스를 제안한다. 제안된 인터페이스를 이용하여 사용자는 HTPC와 떨어진 장소에서 쉽게 HTPC를 제어할 수 있다. 제스처를 인식하기 위해 인터페이스는 실시간 연속 영상으로부터 사용자의 손을 검출하고, 손의 움직임, 모양, 위치 정보를 추출한다. 사용자의 제스처를 인식하기 위해 추출된 정보와 HMMs 을 사용한다. 실험 결과는 제안한 인터페이스가 멀티미디어 응용프로그램뿐만 아니라 다른 종류의 컴퓨터 응용프로그램에서 사용자와 HTPC간에 상호작용하여 접근할 수 있음을 보인다.

Though shared virtual memory (SVM) system promise low cost solutions for high performance computing they suffer from long memory latencies. These latencies are usually caused by repetitive invalidations on shared data. Since shared data are accessed through synchronization and the patterns by which threads synchronizes are repetitive, a prefetching scheme bases on such repetitiveness would reduce memory latencies. Based on this observation, we propose a prefetching technique which predicts future access behavior by analyzing access history per synchronization variable. Our technique was evaluated on an 8-node SVM system using the SPLASH-2 benchmark. The results show the our technique could achieve 34%~45% reduction in memory access latencies.

For people with physical or sensory limitations, broadcasting is the main means of information acquisition and leisure. Recently, changes in the media environment, such as convergence of broadcasting and communication, digital mobile conversion of broadcasting, and active media usage behavior of users, make broadcasting accessibility of the disabled difficult, and as a result, the information gap between the disabled and the non-disabled is increasing. A notice on broadcasting rights for the disabled was enacted in consequence of the amendment of the Broadcasting Law in July 2011 and the web accessibility guideline became more effective with the amendment of the National Informatization Act in 2013 so that legal basis for the right of media access for the disabled was established. However, media services for them are still lacking quantitatively and qualitatively. In this study, we describe the present status of the audio description service for the visually impaired, and analyze the results of the questionnaire survey on the usage status, satisfaction and improvement requirements of the audio description service for 100 visually impaired people.

온실가스 에너지 목표관리제도 뿐만 아니라 배출권거래제도도 도입을 준비하고 있는 등 외부에서 제도의 압박이 거세지고 있다. 기업에서는 온실가스 감축과 관련하여 조직 전부문이 참여하는 실질적 에너지경영체계를 구축해야 하며 조직 외부와 에너지 감축기술에 대한 커뮤니케이션 네트워크를 구성하는 등 기후변화에 대한 대응이 필수적인 사항이 되었다. 이제는 규제대응을 넘어 미래 전략 차원에서 접근과 노력을 해야 한다.

The development of IT technology that has come to symbolize the fourth industrial revolution, the introduction of online government, and the change in environment has caused radical changes in record management. Most public institutions under the government make use of information systems that are objects of information protection such as electronic document system, document management system, and Onnara system. Further, protection and access control of record information through physical environment and electronic system in a user-centered record management environment is an essential component. Hence, this study studies how professional records management professionals in public institutions recognize safe protection and access management of record information, deriving areas that require improvement and providing a discussion and suggestions to bring about such improvement. This study starts by examining laws and policies on information protection in Korea, analyzing items on access control to compare them with laws and policies, as well as the current situation on records management and derive implications. This study is meaningful in that it aims to substantialize records management by suggesting areas of improvement necessary for the protection and management of record information in public institutions and providing professionals with tangible authority and control.
