디지털 정보의 비중과 그에 대한 의존도가 현격이 높여져감에 따라 디지털 정보자원의 효율적인 수집, 저장 방법의 논의가 활발해져가고 있다. 이런 디지털 라이브러리의 분야에서 학술정보의 자유로운 이용(Open Access)에 대한 개념은 확고한 기반을 다져가고 있으며, 기술적 지원으로 제공된 OAI 프로토콜을 활용하여 해외의 학술자료들을 수집, 저장하여 배포하는 과학기술정보 유통체제는 이미 큰 이슈로 자리잡고 있다. 한국과학기술정보연구원(KISTI)은 과학기술중앙정보센터로서 논문, 특허, 연구보고서, 사실정보, 생물다양성정보 등을 비롯한 다양한 종류의 과학기술관련 데이터베이스를 구축, 수집하여 서비스 하고 있다. 이에 국내외 과학기술 정보의 종합포털 및 디지털 전자유통 체제를 확립하기 위해 OAI 프로토콜을 통한 학술자료의 유통이 요구된다. 본 논문에서는 OAI 기반 지식정보 수집 저장시스템인 stOAI(OAI 과학기술유통시스템)을 구축, 개발하였다. 본 시스템은 해외학술자료들을 OAI 프로토콜을 통해 수집 저장하여 Yeskisti(과학기술정보포털서비스)의 OA(Open Access)를 통해 해외저널을 무료로 배포하며 또한, KISITI의 과학기술정보를 효율적으로 외부 정보서비스 연계기관에게 제공하게 된다.

In spite of the development of computers, the present state that a lot of electronic documents are overflowing makes it more difficult for us to get appropriate information. Therefore, it's more important to focus on getting meaningful information than processing the data quickly In this context, Semantic Web enables an intelligent processing by adding semantic metadata on yow web documents. Also, as the Semantic Web grows, the knowledge resources as well as web resources are getting more and more importance. In this paper, we propose an OWL storage system aiming at an intelligent Processing by adding semantic metadata on your web documents, plus a system aiming at an OWL-QL Query Processing.

The international community reached an implicit consensus that knowledge management will be the core of our civilization in the next millenium. This dissertation is to view the knowledge management from the point of information science rather than from the standpoint of the business management, which has been the trends of our academic circle so far. The underlying reason is simple, knowledge is the center of the knowledge management and other factors like humans, organization and culture are merely peripheral elements required to apply knowledge in a more appropriate and efficient manner. This paper looks at knowledge-sharing system as the heart of knowledge management emphasizing significance of the procedures such as validation and valuation and knowledge management processes. Adding to this, I dare to say the term 'Information technology Infrastructure' should be changed into'Information Infrastructure' since knowledge itself and how to express them play a more important role in knowledge management than the information technology does.

IT 기술의 급격한 발달로 인해 개인의 생활뿐만 아니라 국내 기업들의 업무 환경까지도 많은 변화가 일어나고 있다. 이러한 변화 중 가상화 기술을 이용하여 업무의 효율성 증대와 경제적이며 관리 능률의 향상을 기대하며 가상화 환경을 도입하려는 기관이 많이 생겨나고 있다. 하지만 가상화 기술은 안정적인 서버의 운영이 뒷받침 되지 않는다면 막대한 피해를 줄 수 있다. 따라서 본 논문에서는 데스크탑 가상화 환경에서 프로비저닝(Provisioning) 과정을 이용하여 가상 서버의 시스템 자원을 최적화시키고, 최적화된 가상 서버에 사용자VM(Virtual Machine)을 할당하는 부하 분산 방안을 제안한다.

In this paper, I presented that transformation of library from the collection management to knowledge contents management along with paradigm shift under the web-based multimedia information environment is required. Effective web contents management call maximize users'satisfaction with personal customizing services for library users. Especially, contents customizing service using the metabrowsing service contributes to maximize the user'satisfaction by supplying core contents that the user seeks. In this paper, I studied the scheme of knowledge contents management to increase of user'satisfaction, concentrating on the management factors of web-based multimedia knowledge contents and service strategy.

최근 건강에 대한 관심이 높아지면서 의료 분야를 지원하는 애플리케이션 개발이 활발히 이루어지고 있다. 심장의 상태를 곡선으로 나타내는 ECG 를 기반으로 심장병의 유무를 발견하는 애플리케이션은 의료 분야 애플리케이션의 좋은 예라고 할 수 있다. ECG 만으로 질환을 판단하는 것은 제약이 있어, 이를 극복하기 위해 MCG 혹은 가상심장과 같은 다른 자원을 활용하는 것은 좋은 방법이다. 이와 같은 통합 시스템을 지원하려면 각 도메인에 대한 지식이 정의되어야 한다. 이에 본 연구에서는 ECG 와 심장계 질환에 대한 지식을 온톨로지를 이용하여 구축하고 ECG 를 통해 질환을 발견할 수 있는 추론 시스템을 제안하고 프로토타입 시스템을 개발한다.

Ontologies are formal theories that are suitable for implementing the semantic web. which is a new technology that attempts to achieve effective retrieval, integration, and reuse of web resources. Ontologies provide a way of sharing and reusing knowledge among people and heterogeneous applications systems. The role of ontologies is that of making explicit specified conceptualizations. In this context, domain and generic ontologies can be shared, reused, and integrated in the analysis and design stage of information and knowledge systems. This study aims to design an ontology for international organizations. and build an Internet web retrieval system based on the proposed ontology. and finally conduct an experiment to compare the system performance of the proposed system with that of internet search engines focusing relevance and searching time. This study found that average relevance of ontology-based searching and Internet search engines are 4.53 and 2.51, and average searching time of ontology-based searching and Internet search engines are 1.96 minutes and 4.74 minutes.

Information on and knowledge of science and technology in the knowledge-based society can be a valuable natural resource and a source of competitive advantage for a country. In addition, in conducting research and developing technologies, information on and knowledge of science and technology is becoming increasingly important and customer's needs are becoming more diverse. This study thus aims to propose appropriate strategies for effectively coping with needs of those customers who use such knowledge and information by actively reflecting a broad diversity of customer' needs and comments. Using such strategies, we developed a standardized and integrated helpdesk system to enhance the quality of customer support and other services, customer monitoring service, and customer satisfaction.

The knowledge resources take a role in promoting the sustainable growth of organization. Therefore, it is important for the members of organization to acquire knowledge consistently so that the company can continue to grow. Knowledge service is the field that provides information and infrastructure which enable the members of organization to acquire new knowledge. As we recognized the importance of knowledge services, we analyzed the level of knowledge service management and development through the impact of knowledge quality on user capabilities. First, the matrix of knowledge patterns was presented based on the type of information and the level of customer interaction. According to patterns, the knowledge service was classified into three types of information providing, information analysis, and infrastructure, and then the results of structural model analysis were presented for each type. It found that the impact of knowledge service quality on user competence was different according to the type of service. The results suggested new indicators for measuring the performance of knowledge services, and provided information for reconstructing services based on the user considering the integrated operation of knowledge service and organizational designing knowledge service.
