To keep enterprise's competitiveness on condition of the automatic manufacturing system such as FA, FMS and CIM, all the maintenance problems should be considered seriously in not only production and maintenance but also related industrial safety. As we analyze in the surveys for the maintenance management of domestic enterprises and the causes of Industrial accident, there will be necessity of drawing up countermeasures for prevention of industrial accidents and for ensuring expertise maintenance technologies. Based on these analyses, this study studied the safety information system, maintenance management information system, and the machinery condition diagnosis technique by using of the knowledge-based system under the internet environment. This web based knowledge-based diagnosis system can easily provide not only the knowledge of expert about deterioration phenomenon of industrial robot, but also the knowledge of relating safety and facility on everywhere, everytime. Therefore, when we use this system, it is expected to improve the efficiency of business processes in the production and safety.

In this paper, the informative space is proposed to implant ubiquitous functions into physical spaces. We merge physical and virtual spaces through the space structurization using an RFID system, and solve the space localization and mapping problem for a robot to navigate through the distribution and synthesis of information and knowledge. To distribute knowledge flexibly and reliably to changing environment and also to develop a system which allows a robot to invoke and merge the distributed knowledge more freely, we employ a novel approach of knowledge management based on Web services. The proposed method is verified by building a physical space with two kinds of RFID tags and a virtual space with knowledge database based on Web services.

Purpose: The purpose of this study was to develop a web-based education program on control vancomycin-resistant enterococci (VRE) infections and to identify the effects of the program on knowledge and performance of nursing students. Methods: The web-based VRE infection control education program was developed by using the network-based instructional systems design model. The nursing students in the experimental group could access this web-based education program at any time, and as many times as they wanted, during the clinical training period. Effects were evaluated by assessing knowledge and performance of VRE infection control measures during the clinical training period. Results: The contents of the education program included diagnosis, transmission, and treatment of VRE, contact precautions, hand washing, personal protective equipment, environment management, and quizzes. The lecture portion was filmed in a virtual screen studio using flash animation, video, and sound effects, and it was uploaded on an internet site. The knowledge and performance scores of the experimental group after using the education program were significantly higher than those of the control group. Conclusion: The results suggest that the web-based VRE infection control education program is an effective educational method to enhance knowledge and performance of VRE infection control measures.

This paper introduces a search method based on conceptual graph. A hyperlink information is essential to construct conceptual graph in web. The information is very useful as it provides summary and further linkage to construct conceptual graph that has been provided by human. It also has a property which shows review, relation, hierarchy, generality, and visibility. Using this property, we extracted the keywords of web documents and made up of the conceptual graph among the keywords sampled from web pages. This paper extracts the keywords of web pages using anchor text one out of hyperlink information and makes hyperlink of web pages abstract as the link relation between keywords of each web page. 1 suggest this useful search method providing querying word extension or domain knowledge by conceptual graph of keywords. Domain knowledge was conceptualized knowledged as the conceptual graph. Then it is not listing web documents which is the defect of previous search system. And it gives the index of concept associating with querying word.

본 연구 목적은 웹 페이지 설계자가 가지고 있는 WWW에 대한 지식구조를 조사하는데 있다. 이를 위해, 공공도서관 웹 사이트를 연구대상으로 하였으며, 독립변인으로 공공도서관의 운영주체를 선택하여, 공공도서관 웹 페이지에서 링크하고 있는 관종별 도서관과, 운영주체 기관 웹 사이트, 그리고 생활정보 사이트를 대상으로 분석하였다. 연구 결과, 운영주체에 따라 전문ㆍ특수도서관을 링크하는데 차이점을 보여주고 있었으며, 운영주체 기관에 대해서도 다른 점을 보여주었다. 이러한 차이점은 지리적인 요인과 링크된 웹 사이트에서 제공하는 정보의 형태에 따라 차이가 나는 것으로 나타났다.

본 연구에서는 웹기반 멀티미디어 정보환경에서 자원관리 패러다임 변화와 함께 도서관의 장서관리가 지식컨텐츠관리로 변화할 필요성을 제시하였다. 효율적인 웹 컨텐츠관리는 개인별 맞춤화 서비스를 제공함으로서 궁극적으로 이용자 만족을 최대화 할 수 있다. 특히, 메타브라우징 방식을 이용한 컨텐츠 맞춤화 서비스는 이용자 개인이 일하는 핵심컨텐츠만을 집중 서비스함으로서 이용자 만족의 극대화에 기여한다. 본 연구에서는 이와같이 이용자의 만족을 강화하기 위한 웹 기반 멀티미디어 지식컨텐트 관리방안에 대해서 관리요소와 서비스방안을 중심으로 연구하였다.

본 논문에서는 Hadoop MapReduce 병렬 분산 컴퓨팅 환경을 이용해 개발한 공간 지식 추출기를 제안한다. 이 공간 지식 추출기는 대용량의 공간 데이터 집합으로부터, 임의의 두 공간 객체들 사이에 만족되는 위상 관계와 방향 관계를 나타내는 정성 공간 지식 베이스를 생성해낸다. 본 논문에서 제안하는 MapReduce 기반의 대용량 공간 지식 추출기 MRSPAKE는 HDFS 상의 분산 공간 데이터 파일에 대한 R 트리 색인과 범위 질의들을 이용함으로써, 웹 규모의 정성 공간 지식 베이스를 매우 효율적으로 추출해낸다. 대표적인 공개 데이터 집합인 Open Street Map(OSM)을 이용한 성능 분석 실험을 통해, 본 논문에서 제안하는 웹 규모의 공간 지식 추출기 MRSPAKE의 높은 성능과 확장성을 확인할 수 있었다.

본 연구는 재미 한인 이민자들의 교육수준, 체류기간, 영어실력 변인들이 전통 뉴스매체(텔레비전, 신문, 라디오, 시사잡지)와 뉴스 웹 이용에 어떻게 영향을 주고, 전통뉴스매체와 웹 이용은 그들의 정치지식, 정치관심, 정치활동 참여 증진에 유의미한 영향을 미치는 지를 고찰했다. 연구결과는 다음과 같다. 첫째, 교육, 체류기간, 영어실력 변인들은 주류사회의 전통 뉴스매체의 매개적 역할을 거쳐 한인 이민자들의 정치지식, 정치관심, 정치활동참여를 증진시키는 것으로 나타났다. 둘째, 한인 이민자들에 의한 미국 뉴스 웹 이용은 주류정치에 대한 관심을 증진시키는 것으로 나타났다. 셋째, 한국어 전통 뉴스매체 이용 역시 주류정치에 대한 관심을 증진시키는 것으로 나타났다. 넷째, 한국어 뉴스 웹사이트 이용은 정치사회화에 유의미한 역할을 하지 못하는 것으로 나타났다. 결론적으로 이민자들의 주류 정치사회화 과정에서는 인터넷 웹사이트가 제공하는 뉴스보다는 전통매체 특히, 주류사회의 전통뉴스매체의 역할이 매우 중요한 것으로 밝혀졌다.

Web 2.0, characterized as openness, sharing, and participation, has enabled Internet users to easily generate a variety of contents, and to share them through Web 2.0 services. Knowledge search service (KSS) is positioning itself as one of typical Web 2.0 services. Yet, few studies have sharpened our understanding of users' knowledge sharing behavior in the KSS environment. In order to address this knowledge void, this paper attempts to explore antecedents of their usage behavior in the KSS environment. Typically, they utilize stored knowledge and share their knowledge simultaneously. Considering this characteristic, our study regards service usage intention and knowledge sharing intention as final dependent variables. This study advances a research model based on Bhattacherjee's expectation-confirmation model, which is expanded by incorporating trust belief. Because of the openness of KSS, trust belief is believed to play a critical role in forming users' service usage intention and knowledge sharing intention. Furthermore, this study examines the difference of the antecedents' effects in terms of users' gender. We collected data from 275 respondents who have experience in using KSS. PLS (partial least squares) was employed for the analysis of the data. Analysis results confirm the important role of user satisfaction and trust belief in the formation of users' service usage intention and knowledge sharing intention. More importantly, trust belief has a more salient effect on knowledge service usage intention than user satisfaction. This study also shows the moderating role of users' gender. Finally, this paper provides managerial guidance on strategic planning aimed at improving users' service usage intention and knowledge sharing intention in the KSS environment.
