Each equipment has a durable life. The state of the equipment may change or fail until it is introduced, operated and disposed of. It is difficult for each organization to have a significant amount of these equipment and to understand each issue. Therefore, systematic life cycle management of equipment is more necessary than just for inventory purposes. In this paper, we design and implement an integrated management system for information assets. If it is an environment that can use the Internet based on the web, it can easily and easily access computerized information resource data through PCs, tablets, and smartphones. In addition, an integrated management system was established to limit the functions of higher and lower institutions through centralized management and user-level empowerment methods and to understand the overall status of resources.

Interoperability between heterogeneous domains is a very important point considered in the field of scholarly information service as well information standardization. In case of the large information system, interoperability between internal information resources becomes to affect the performance of the whole system. The automatic method for understanding heterogeneous system environment will be very helpful to solve the problems like this. This paper shows that automatic method for interoperability between heterogeneous scholarly classification code structures will be effective in enhancing the information service system.

Information modeling that is broadly applied in digital archiving process privides conceptual process that can be used to guide the creation of descriptions for the objects of preservation. However, it has faced with the limitations on substantially applying to the creation of preservation metadata records. This research proposes the concept of Resource Cluster in order to address these problems and efficiently describe the objects of preservation during digital archiving process. It also constructed Preservation Description Framework (PDF) based on RDF in order to substantially manifest preservation descriptions. This framework combines the structure of OAIS Reference Model and Functional Requirements for Bibliographic Records (FRBR) and can be an alternative approach to the creation of preservation metadata in more efficient and effective ways.

KISTI 슈퍼컴퓨터 시스템은 슈퍼컴사용자가 하나의 계정(account)으로 여러 번에 걸쳐서 CPU Time을 구매하여 사용하는 체계이며, 그 계정에 소속된 다수의 연구원에게 각각 로그인 아이디가 발급되어 하나의 계정으로 슈퍼컴 사용량이 과금(charging)되는 것이 계정관리 체계이다. 그리고, 슈퍼컴을 유료로 사용하는 방법이외에 창의적인 아이디어 또는 거대과학 문제를 가진 국내 연구자가 슈퍼컴퓨팅 자원을 이용하여 세계 수준의 연구 성과를 창출할 수 있도록 슈퍼컴퓨팅 자원을 무료로 제공하는 지원사업이 있다. 사용자는 유료계정외에 무료인 지원사업 계정을 보유 관리하여야 하며, 지원사업 운영정책과 통계 정보 관리상 슈퍼컴퓨터 사용은 별개의 계정과 로그인 아이디로 각각 사용하여야 하는 이원체계로 되어 있다. 만약, 사용자가 작업에 따라 과금계정을 개별적으로 지정할 수 있는 기능이 있다면, 하나의 아이디를 계속 사용하는 단일체계의 활용이 되는 것이다. 본 논문에서는 하나의 로그인 아이디로 여러 개의 계정으로 과금할 수 있도록 사용자가 과금계정을 선택할 수 있는 동적자원할당시스템(Dynamic Resource Allocation System, DRAS)을 만들어 계정관리 체계를 개선하고자 한다.

This paper proposes an efficient market mechanism-based resource transaction model for grid computing. This model predicts the next resource demand of users and suggests reasonable resource price for both of customers and resource providers. This model increases resource transactions between customers and resource providers and reduces the average of transaction response times from resource providers. For prediction accuracy improvement of resource demands and suggestion of reasonable resource price, this model introduces a statistics-based prediction model and a price decision model of microeconomics. For performance evaluating, this paper measures resource demand prediction accuracy rate of users, response time of resource transaction, the number of resource transactions, and resource utilization. With 87.45% of reliable prediction accuracy, this model works on the less 72.39% of response time than existing resource transaction models in a grid computing environment. The number of transactions and the resource utilization increase up to 162.56% and up to 230%, respectively.

There is a recognition that traditional resource sharing methods such as interlibrary lending and document delivery are now inadequate to meet user needs in the increasingly networked environment. The current study identifies barriers to resource sharing and provides analysis of stakeholders engaged in resource sharing. Focused interviews with six professional librarians were also carried out to seek out deeper understanding of perceptions of barriers among librarians. Results show that the size of the library was not necessarily result in active resource sharing. There was a wide gap among librarians in terms of their attitudinal and organizational orientations towards resource sharing. Barriers specifically identified in the study include the narrowly defined notion among librarians of what constitutes research and the untested fear of swamping where there is an imbalance of collections. Overall, while resource sharing is recognized as an integral part of library services, it seriously lacks funding and staff. The study recommends earnest efforts to build librarians' community to invigorate resource sharing among libraries.

In order to promote the volunteer activity management of public libraries, the need on the standard manual for volunteer activity of public libraries has become inevitably urgent. In this context, this study builds a theoretical background on the volunteer activity of public libraries, on its management and on its standard manual; examines the volunteer activity management of public libraries including its planning, personal management and administration; and classifies them into twelve domains and six work flows based on the literature review and case studies; and develops the standard manual for volunteer activity of public libraries. By so doing, this study aims at enhancing our understanding on the volunteer activity management of public libraries.

방대한 양의 분산 멀티미디어 자원에 대한 엑세스를 제공하는 하이퍼미디어 기능을 사용한 WWW의 성공은 정보관리 시스템의 구성요소로써 하이퍼미디어 항해자의 실행 가능성에 대한 확고한 증거를 제공한다. 그러나 논 논문에서는 현존하는 하이퍼미디어 시스템에 거의 없는 필요한 모든 기능을 제공하는 방법을 보였다. 개방형 분산 멀티미디어 자원 통합 모델의모든 기능을 제공해 주기 위하여 개방형 분산 하이퍼미디어 계층의 프리젠테이션 계층과 양질의 서비스 계층을 통하여 융통성 있고 확장 가능한 분산 멀티미디어 정보 시스템이 개발될 수 있는 범위 내의 모듈러 프레임워크(modular framework)로써 행동하도록 설계되었다. 개방형 분산 하이퍼 미디어 프레임 워크 모델은 QoS(Quality of Service)제공을 위하여 이질적인 분산 멀티미디어 자원 통합의 하이퍼미디어 프레임워크 모델을 하이퍼미디어 세션과 함께 제시함으로써 넓게 분산되어 있는 자원에 대하여 투명하게 접근할 수 있는 방법을 제시하였다.

기존의 인폼드 검색 모델에서 자원 보유 피어의 검색 결과는 검색 과정에서 선택된 피어들 각각의 라우팅 결정 정보로 저장되는데, 자원 적중률에 따라 다음 피어를 선택할 때 주요 결정 요인으로 작용한다. 이러한 라우팅 결정 정보를 이용하여 검색 트래픽과 검색 성공률 등의 측면에서 기존의 Random Walks 등에 비해 효과적인 성능 평가 결과를 보인 LTO(Leveled The Orienteering) 검색 알고리즘은 검색 과정에서의 라우팅 경로가 편중되어 있어 해당 노드들에 검색 부하 집중 경향을 보인다. 이에 본 논문에서는 검색 적중 빈도에 다라 LTO 검색 알고리즘이 검색 과정상에서 라우트 대상 노드들의 성능을 고려한 적응적 P2P 검색 알고리즘으로 확장 제안한다. 제안한 알고리즘의 성능 평가 결과 노드들의 검색 부하 집중률과 자원 검색 노드의 검색 성공률 측면에서 적절한 타협점에서 동작함을 확인하였다.

This study is to suggest a classification system to classify the agricultural information resources on the internet. In the first part, I analyzes KDC's class 520(agriculture science). The second part compares the agricultural classes of Yahoo! Korea with those of Empas search engine. The third part compares the classes of AFFIS with Agri_Directory. Based on the comparative analysis, it proposes a classificatory system for the agricultural information resources on the internet.
