The concept of the sharing economy, which has shifted the economic paradigm from possession to access to resources, is consistent with the traditional and current roles of public libraries. Thus, this research empirically analyzed the influence relationships between public library use and the sharing economy. Results showed that participation in public library programs serves as a motivational factor for satisfaction with and trust in the sharing economy, while the use of public library facilities and equipment is correlated with attitudes toward and participation in the sharing economy. The use of library collections positively influences sharing intangible resources such as knowledge, information, and personal experience. By contrast, checking out library resources negatively influences the recognition of economic benefits from sharing, which is contrary to claims of library communities. Based on these results, public libraries should aim to have a complementary effect on the sharing economy founded not only on information networks but also human networks grounded in social relationships.

Mobile Internet using mobile devices provides Portability to users and is Spreading throughout out lives. But Practical use of the mobile Internet is insufficient due to it's fundamental limitations. Especially, mobile resources are not sufficient because they are not closely connected under current mobile Internet services which are provided with pre-designed structure. For these reasons it will take a lot more time and effort for mobile Internet to grow as a popular service. In this paper, we are focusing to overcome the local limitation and to enhance the 'Sharing of Mobile Resources' by expanding mutual connectivity between resource objects scattered over the mobile Internet environment. To archive this, we propose the MRSS(Mobile Resources Sharing System). MRSS automatically converts single request from user to multiple instructions based on 'Context-Awareness' to search for proper information. Using MRSS, we can expect 'Mobile Ubiquitous Computing' environment which users can reach to information anywhere, anytime.

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.

In case of scheduling tasks with shared resources in multiprocessor systems, Global Earliest Deadline First (GEDF) algorithm, equally applied Earliest Deadline First (EDF) which runs scheduling with deadline criterion, makes schedulability decline because GEDF typically does not have a specific process in order to handle tasks with shared resources. In this paper, we propose Earliest Deadline First with Partitioning (EDFP) for tasks with shared resources which partitions a task into two kinds of subtasks that include critical sections to access to shared resources, gives their own deadline respectively and manages them. As a result of simulations, EDFP shows better performance than GEDF for tasks with shared resources since system load goes up and the number of processor increases.

객체지향 프로그래밍의 발달과 필요성에 따라 분산된 통신망에도 객체지향 기술이 적용되는 분산객체 컴퓨팅이 새로운 버젼으로 대중화되고 있다 따라서 분산 객체간의 자원을 효율적으로 이용하고 다른 통신망의 사용자들과 원활한 통신을 하기 위해서는 자원의 공유가 필연적이다. 그러나 이러한 정보와 자원의 공유는 불완전한 통신 채널을 통해 이루어지기 때문에 불법적인 사용자들이 정보를 악용하는 보안상의 문제가 발생한다. 본 논문은 다양한 컴퓨팅 자원들이 통신망으로 연결되어 있는 개방형 분산 객체 컴퓨팅 환경에서 운영되는 컴퓨터 통신망의 정보를 보호하고 정당한 사용자에게 자원을 효율적으로 제공할 수 있는 인증 메카니즘으로 CORBA 환경에서 티켓을 사용하지 않은 Kerberos 인증을 제안하였다.

Today, despite the increase in professional knowledge-related information needs of citizens, the expansion of citizen participatory research in academia, and the provision of information services for the professional knowledge, there are still difficulties in access to scholarly information resources by laypeople. Focusing on this problem, this study investigates laypeople's scholarly information needs and behaviors through a questionnaire survey. By examining the search and use behaviors of scholarly information resources, and the perception of the need to support the utilization of them, this study analyzes the degree and pattern of social sharing of scholarly information resources beyond the scholarly community. This study is significant in that it expands the range of users in traditional scholarly communication and emphasizes the need to support them to access and use scholarly information resources.

본고는 개입 게임(Intervention Game)을 이용한 효율적인 자원공유 방법에 대해 알아본다. 무선통신과 같이 제한된 무선자원을 효과적으로 사용하기 위한 자원공유 방법으로 개입 게임을 이용할 수 있으며, 개입 장치에 의해 자원공유가 조절된다. 개입 장치는 사용자의 행동을 관찰하여 행동에 따른 처벌을 제공하는 장치로 모니터링 능력과 사용자들의 행동에 개입 할 수 있는 개입 능력으로 특정지을 수 있다. 개입 장치가 모니터링 할 수 있는 정보량과 개입량에 따라 다양한 개입 게임이 존재할 수 있으며, 개입 게임을 통해 시스템 관점에서 이상적인 자원공유를 이룰 수 있다. 본고에서는 개입 게임에 대해 알아보고, 기존의 접근 방법과의 차이점에 대해 알아본다. 또한, 개입게임을 모델링하고, 개입 게임을 사용한 간단한 통신 시나리오를 소개한다.

연구 개발자들은 자신의 정보활동에 있어 전체 활동의 20 ${\sim}$ 40%를 관련 정보의 탐색 및 분석에 사용하고 정보활동 결과는 개인 컴퓨터에 저장한다. 그러나 개인 컴퓨터상의 유용한 정보는 정보관리 및 공유 도구의 부재로 인하여 가치 및 유용성을 상실하고 있다. 본 연구에서는 데스크 탑 서치와 P2P 기반의 정보공유 기능을 갖는 시스템을 제안한다. 데스크 탑 서치를 통하여 연구 개발자는 본인의 컴퓨터에 저장된 정보를 효율적으로 활용할 수 있다. 연구 개발자들이 많은 시간을 들여 축적한 유용한 정보자원을 쉽게 공유할 수 있게 하는 P2P 기반의 정보공유는 연구개발 활동의 전체적인 생산성을 높일 수 있다.

In this study, we analyzed the effects of how Human resource management affects the knowledge sharing that facilitates organizational performance. Human resource management has received very little attention in the study of knowledge management. However, main drivers of knowledge activities are individual members of an organization and thus knowledge management strategies should be discussed in relation with human resource management. The results show that human resource management was significantly positively related to knowledge sharing, and the relationship between human resource management and organizational performance was partially mediated by knowledge sharing. Lessons and implications of this study for management leadership are presented.

Sharing knowledge is an important factor in the discourses on the knowledge management on the campus. This article analyzed the impact of organizational context on faculty's perceptions of knowledge-sharing capabilities in the university. As a result, perceptions of knowledge-sharing capabilities and performance-based reward systems were found to significantly affect faculty knowledge-sharing capabilities in the university studied. Also, results from multivariate analysis showed that the faculty's perception of knowledge-sharing more significantly affected knowledge-sharing than reward system.
