  • 본 연구는 빠르게 발전되는 네트워크 환경을 고려한 분산된 자원 활용에 필요한 기반 연구이다. 앞으로의 자원공유에 대한 노력은 기술적인 문제가 아닌 의미져인 상호운용성이 강조되어야 한다. 이를 위해 본 연구에서는 자원공유를 위한 컬렉션 단위 기술(collection level description; 이하 CLD라고 함) 모형을 제안하였다. 먼저 컬렉션의 범위, 구축목적, 관련 행위자들을 기반으로 하여 컬렉션에 대한 정의를 설명하였으며, CLD의 중요성을 강조한 연구와 그와 관련된 표준들을 비교 분석하였다. 마지막으로는 기존의 CLD의 기능에서 보강되어야 할 관계 중심의 모형 구축을 시도하였으며, 이를 위해 온톨로지 개념을 사용하였다. 온톨로지기반 CLD 모형은 새로운 관계를 창출하기 위한 다양한 표현 기술들을 정의하였다. 기존 연구와는 달리 클래스와 속성을 구별하고, 속성 중에서도 클래스 자체에 대한 특성과 클래스들 간의 관계를 연결하는 속성으로 나누어서 제시하였다.

  • In NCW(Network Centric Warfare) environment, mobile nodes communicate through wireless link. But wireless link provides limited networking performance due to signal interferences or mobility of nodes. So it is quite challenge to acquire enough networking resources and use the resources efficiently. In this paper, we have proposed a P2P based tactical information sharing system which provides satisfactory visual information playout for mobile nodes(i.e., military personnel, vehicle,..) in NCW environment. Our proposed system consists of two components. One is caching-enabled switch which stores tactical information segments at its internal storage and then transports them to mobile nodes when require. Another is centralized scheduling algorithm which exploits networking resources more efficiently. To validate performance of proposed system, we performed series of experiments in wireless network testbed. Results show improved performance in terms of segment-missing ratio, networking resources usage, sharing time, and number of simultaneous playout mobile nodes with acceptable playout continuity(i.e., over 95%).

  • This paper discussed the factors that necessitated information networking, types of networks, benefits of information networking, library information networking and the University of Port 0Harcourt library network initiatives. Information networking is a process of communication, exchange of ideas, resource sharing and collaboration between individuals, organizations, institutions and libraries and it is facilitated by ICTs and the internet for improved accessibility. It has been brought about by information explosion, rapid advancement in information communication technologies, inadequate funding and increased demand for quality information. Networks can be classified into local, national, regional, and international networks and are formed to serve different categories of user communities. Benefits of information networking include resource sharing, on-line conferences and participation in programmes at distant centers, collaboration among scholars in different countries. Communication flow through the internet, social media, and electronic mail. Library information networking started with the interlibrary loan which has metamorphosed into library consortia in which groups of libraries partner to coordinate activities, share resources and combine expertise. The University of Port Harcourt Library network initiatives started with an e-granary (a CD ROM) and the establishment of a local area network. The library subscribes to more than 10 electronic databases. Information networking has greatly improved the sharing of resources in acquisition and dissemination of information resources since no single institution can acquire the overwhelming number of information resources in their various formats.

  • Recently, various wearable personal devices such as a smart watch have been developed and these personal devices are being miniaturized. The user desires to receive new services from personal devices as well as services that have been received from personal computers, anytime and anywhere. However, miniaturization of devices involves constraints on resources such as limited input and output and insufficient power. In order to solve these resource constraints, this paper proposes a resource collaboration system which provides a service by composing sharable resources in the resource sharing environment like IoT. the paper also propose a method to infer and recommend user-customized resources among various sharable resources. For this purpose, the paper defines an ontology for resource inference. This paper also classifies users behavior types based on a user model and then uses them for resource recommendation. The paper implements the proposed method as a prototype system on a personal device with limited resources developed for resource collaboration and shows the effectiveness of the proposed method by evaluating user satisfaction.

  • Objectives : The 10th Conference of the Parties to the Convention on Biological Diversity (COP 10) was held in Nagoya, Japan in October 2010, during which an international convention on access to genetic resources and conventional knowledge and sharing of benefits thereof was adopted. The Oriental Medicine field uses medicinal herbs based on genetic resources, as well as traditional knowledge about genetic resources. As such, if Korea, China and Japan compete over the ownership of such traditional knowledge, it will almost certainly trigger disputes over the payment of royalties among other problems. Notably, since the traditional medicine industry is closely related with China, it is highly likely this will adversely affect Korea's production of medicines using natural materials, including Korean herbal doctors' prescription, formulation and preparation of medicinal herbs. Methods : This study also analyzed the recent situation in Japan, which is the chair nation of the Nagoya Protocol and a member nation like Korea. It analyzed the Japanese people's awareness of the Nagoya Protocol and its strategies in the two years since its adoption, as well as the Guidelines for Genetic Resources, which were newly revised in 2012. Conclusions : The Nagoya Protocol requires the preparation of legislative and administrative measures and policies in order to pave the way for sharing the benefits deriving from the use of genetic resources and the relevant traditional knowledge with the providers of such resources. Thus, corresponding domestic legal measures need to be taken. Such measures include the refining of the procedure of accessing genetic resources, the designation of liaison offices, a competent agency and a supervisory agency, and the building of a system designed to issue internationally acknowledged certificates. It is also important to operate related professional consulting offices, as is the case in Japan. In addition, in the case of genetic resources, there is a need to seek multinational and bilateral cooperation including free trade agreements. Regarding traditional knowledge about genetic resources, measures need to be prepared to enable the three East Asian countries, namely, Korea, China and Japan, to commonly use ancient literature on Oriental medicine and to claim exclusive rights to such intellectual properties. Notably, with China now moving to expand the scope of traditional knowledge through the WIPO, Korea needs to prepare response measures.

  • Many companies have tried, with mixed success, to leverage knowledge resources by knowledge sharing functions. Trust is one of the integral factors for fostering knowledge sharing. This paper categorizes trust on the basis of its multi-dimension and multi-level. In view of this category, it investigates the relationship between trust and knowledge sharing. A sample of 191 employees from 24 companies is used for an empirical exploration. Our analysis results imply that both organizational trust and trust among peers are crucial for effective knowledge sharing.
