This paper introduces an approach to ontology-based framework for knowledge management in a product development domain. The participants in a product life cycle want to share the product knowledge without any heterogeneity. However, previous knowledge management systems do not have any conceptual specifications of their knowledge. We suggest the three levels of knowledge framework. First level is an axiom, which specifies the semantics of concepts and relations. Second level is a product development knowledge map. It defines the common domain knowledge which domain experts agree with. Third level is a specialized knowledge for domain, which includes three knowledge types; expert knowledge, engineering function and data-analysis-based knowledge. We propose an ontology-based knowledge framework based on the three levels of knowledge. The framework has a uniform representation; first order logic to increase integrity of the framework. We implement the framework using prolog and test example queries to show the effectiveness of the framework.

A CAD system of grid element for vacuum fluorescent disply has been developed. In order to reduce design man-houre and human erros, it is used to automate the design process using a knowledge base system. In the case of VFD product design, the most important consideration is the short-life cycle. So the development of CAD system for VFD product is needed. The developed system is based on the knowledge base system which is involved in a lot of expert's technology in the practice field. Using C-language under the HP-UNIX system, CIS customer language of the EXCESS CAD/CAM is used as the overall CAD environment. Results of this system will provide effective aids to the designer in this field

Nowadays the Project Management is increasingly adapted into almost all the fields in business management processes among leading companies both in Korea and overseas. However its actual practices are rare to be found. Among the Project Life Cycle, this report covers the real cases of the PMBOK knowledge areas in NPP Architect Engineering. The areas of the Construction, Start-up and Operation will be exception of the cases. By way of analyzing the KEPCO ENC's Processes/Procedures/Systems and the ones in PMBOK Guide, this report will show the contents in the PMBOK Guide is rather practical than theoretical. Meanwhile, implications whether the conclusions of this report might be applied to other industries such as general construction, non-nuclear plants, etc. should be left behind to follow-up studies.

A company needs low cost and high efficient S/W tools to improve the white color productivity in daily operation, These needs may be satisfied by end-user knowledge management system to be suggested in this paper. We suggest that the end-user knowledge management is not made by specialized developer but directly made by end-users of some related managers using company-wide DB and department DB. We expect that this end-user knowledge management system will increase the efficiency of end-user daily operation and minimize the total life cycle cost of end-user computing system in industry. The suggested end-user knowledge management system has been tested in some companies through the training course.

This study relates to develop a quantitative method through which promising technology-based business items can be discovered and selected. For this study, we utilized patent trend analysis, technology-industry concordance analysis, and keyword co-occurrence analysis of US patents. By analyzing patent trends and technology-industry concordance, we were able to find out the emerging industry trends : prevalence of bio industry, service industry, and B2C business. From the direct and co-occurrence analysis of newly discovered patent keywords in the year, 2000, 28 promising business item candidates were extracted. Finally, the promising item candidates were prioritized using 4 business attractiveness determinants; market size, product life cycle, degree of the technological innovation, and coincidence with the industry trends. This result implicates that reliable discovery and selection of promising technology-based business items can be performed by a quantitative, objective and low- cost process using knowledge discovery method from patent database instead of peer review.

For decades, thousands of corporation introduced knowledge management systems to respond knowledge-based society. However, it seems that the systems merely focusing on knowledge accumulation and its sharing have been bounded by many restrictions in terms of new knowledge creation based on the life cycle of knowledge management systems. Moreover, recently, a variety of knowledge management activities regarding organization, systems, and process is emphasized as a strategic asset for a corporation to create core knowledge. Therefore, this study adopted the Csikszentmihalyi's flow theory to investigate the factors affecting knowledge creation and the success factors of knowledge management systems in virtual space. Prior studies argued that flow experience should be a prerequisite for creative knowledge creation. In that vein, this research revealed the causal relationships for flow experience between the determinants of clear goal, immediate feedback, congruence of challenge and skill. Additionally, it empirically examined how flow experience affected the exploratory behavior of knowledge creation.

전문용어는 사전, 시소러스 및 온톨로지를 비롯한 다양한 기반지식자원에서 사용되고 있으며, 해당분야 발전에 민감하게 반응하는 특징을 가진다. 그럼에도 불구하고, 용어를 생명주기 관점에서 바라보고 이를 효율적으로 사용할 수 있도록 하는 연구가 부족하다. 본 논문에서는 한정된 인적${\cdot}$물적 자원을 효율적으로 사용할 수 있도록 가까운 미래에도 유용한 용어들을 선정하고 관리하기 위한 방안으로서 용어지배값 (TDV; Term Dominance Value)을 제안한다. 이를 통해 용어 생명주기의 각 단계를 생성, 성장, 유지, 쇠퇴, 소멸, 재생 등으로 정의함으로써 관리해야 할 대상 용어를 명확히 할 수 있도록 한다. 용어지배값과 Coverage와의 관계 실험을 통해 유망한 용어들을 선정하고 관리해야 하는 당위성을 보여준다.

최근 소프트웨어 개발에 적용하기 시작한 객체지향 방법(OOM:Object-Oriented Method)은 독립적인 소프트웨어의 재사용을 통한 개발 비용과 시간의 단축을 강조하고 있다. 그러나 개발 기술에 대한 지식 부족과 확장성 및 성능을 배제한 설계로 많은 문제점이 나타나고 있다. 따라서 본 논문에서는 소프트웨어 개발 생명주기에서 소프트웨어 생산성 향상을 위한 효율적인 객체지향 모델링 방법을 제안하고자 한다. 제안 방법은 Use Case 모델링, 분석 모델링, 그리고 설계 모델링 방법들을 포함하고 있다.

In the 4th Industrial Revolution and changes in the construction industry market, the importance of information management is becoming more emphasized. For efficient use of information, construction data must be collected, processed and analyzed more quickly and accurately, depending on the purpose of the project. Thus, data could be utilized as integrated knowledge. However, there is a limit to searching or managing construction information produced in various formats over the entire life cycle by index words. Therefore, this study proposes a construction information integrated management plan that reflects the characteristics of the construction industry by applying the OWL concept. For this, as an initial study, an architectural object of small size and clear features was needed. Therefore, a construction information management study using OWL was conducted for Korean traditional architectural style houses (Hanok) which has these characteristics.

Purpose: This study aimed to evaluate the effects of sex education, focusing on the sexual activities of the elderly, on high school girls' sexual knowledge, attitudes, and perceptions. Methods: A quasi-experimental pre-post design was used, and the data of 82 participants (41 in each group) were analyzed. The educational effects were assessed through sexual knowledge, attitudes, and perceptions. The data were analyzed through SPSS 18.0, using descriptive statistics, chi-square tests, and paired t-tests. Results: The experimental and control groups had similar demographics. Sex education was effective in increasing sexual knowledge (p<.001), and changing the attitudes (p<.001) and perceptions (p<.001) of members of the experimental group for the better. Conclusions: This study has shown that sex education can improve high school girls' understanding of elderly sexual activities. This study is meaningful in that, it sought to facilitate a positive change in young people's attitudes towards elderly sexuality and quality of life.
