  • Purpose : This study was to describe health behavior, self-esteem, health knowledge, health education needs, and to assess the effects of health behavior on self-esteem, health knowledge and health education needs. Study Methods : A self-administrated questionnaire was carried out to randomly selected students in two middle schools in Seoul, Korea. The questionnaire contains items of health behavior on self-esteem, health knowledge and health education needs. Results : The mean score differences of health behavior were not meaningful. Health behavior had significantly positive correlation with self-esteem, health knowledge and health education needs. The multiple regression showed that higher self-esteem, health knowledge and health education needs was associated with higher scores of health behavior. Discussion : Health knowledge has a significant effect on health behavior Therefore, regular health education class must be based on health knowledge and health education needs.

  • Knowledge sharing occurs through voluntary interactions between human actors. In this paper, from the perspective of social interaction, the effect of transactive memory capability and social capital (bridging social capital and bonding social capital) on knowledge sharing intention was analyzed, and tenure was demonstrated as a moderating factor that can strengthen their relationship. Therefore, the results of this study are summarized as follows. First, it was verified that the transactive memory capability had a significant positive effect on the knowledge sharing intention. Second, it was found that the bridging social capital and bonding social capital held by individuals had a significant positive effect on knowledge sharing intention. Social capital is understood to form an individual's voluntary motivation for knowledge sharing. Third, it was verified that the moderating effect of tenure suggested in this study was not significant. Based on the results of this study, implications and future research directions were presented.

  • The purpose of this study is to investigate the relationship between knowledge sharing and academic performance in the context of quality-assurance related work. It furthermore aims to explore the role of information technology in mediating this relationship. Quantitative method was applied to collect data from the participants using an online-based questionnaire. Convenience sampling technique was used. The responses were collected from 140 participants in a university from Saudi Arabia. The study found a strong positive relationship between knowledge sharing and individual performance. It was also found out that information technology partially mediates the relationship between knowledge sharing and individual performance. The research unearths the significant contribution made by information technology in mediating the relationship between individual-level knowledge sharing and the individual performance. This helps to understand the positive impacts on individual work performance in institutions of higher education that would be derived if individuals use various forms of IT to share knowledge. The focus of the research is the individual performance as the pertinent contribution towards positive outcomes in institutional performance.

  • 다양한 정보자원들로부터 사용자가 요구하는 맞춤화된 정보를 추출해 내는 것은 더욱 어려워지고 있다. RSS를 비롯하여 개선된 다양한 정보 수집 방법들이 개발되었지만, 여전히 정보가공자인 사람의 도움 없이 필요한 정보들을 수집하여 정리 및 가공하는 작업이 쉽지는 않다. 따라서 본 연구에서는 정보사용자들이 사용 목적에 맞게 정보를 가공하는 부담을 줄여주기 위해 사례기반추론과 온톨로지에 기반한 맞춤형 통합정보생성 프레임워크를 제안한다. 본 프레임워크는 세 단계로 구성된다. 첫째, 수집된 웹 정보를 정보가공의 용이성을 위해 사례로 변환한다. 둘째, 동적 유사도 검색을 통해 수집된 사례들로부터 정보 사용자의 동적 요구사항에 적합한 사례를 검색한다. 셋째, 전 단계에서 추출된 사례를 정보사용자의 요구사항에 보다 적합한 지식으로 가공하기 위해 집중 유사도를 적용한다. 본 프레임워크는 여행자들의 정보수집을 위한 여행정보시스템에 적용되어 그 효과를 입증하였다.

  • This paper describes a research work of developing a computer-aided design of product with bending and piercing for progressive working. An approach to the system for progressive working is based on the knowledge-based rules. Knowledge for the system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system has been written in AutoLISP on the AutoCAD with a personal computer and is composed of four main modules, which are input and shape treatment, flat pattern layout, strip layout and die layout module. Based on knowledge-based rules, the system is designed by considering several factors such as radius and angle of bend, material and thickness of product, complexities of blank geometry and punch profile, bending sequence, and availability of press. Strip layout drawing generated by the piercing processes with punch profiles divided into for external area is simulated in 3-D graphic forms, including bending sequences for the product with piercing and bending. Results obtained using the modules enable the manufacturer for progressive working of electronic products to be more efficient in this field.

  • This paper describes a research work of developing a computer-aided design of blanking and piercing for irregular-shaped sheet metal products. An approach to the development of compact and practical CAB system is based on the knowledge-based rules. Knowledge for the CAD system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system has been written in AutoLISP on the AutoCAD with a personal computer. Based on knowledge-based rules, the system, STRT-DES, is designed by considering several factors, such as complexities of blank geometry and punch profile, availability of press equipment and standard parts, utilization ratio which minimizes the scrap in a single or a pairwise operation, bridge width, grain orientation and design requirements which maximize the strength of the part when subsequent bending is involved. This system checks a forming feasibility with both internal and external features, a dimension of blanked hole, and a corner and a fillet radius for irregualrly shaped sheet metal products. Therefore this system can carry out a die design for each process which is obtained from results of an automated blank layout drawing with a best utilization ratio for irregular shape of product that was successful in production feasibility check module and those of an automated strip layout drawing and generate part drawings and the assembly drawing of die set in graphic forms.

  • 본 연구는 배뇨곤란 환자 사례기반 교육이 간호 대학생의 단순도뇨 지식, 단순도뇨 자신감 및 단순도뇨 술기능력에 미치는 효과를 확인하기 위한 연구이다. 본 연구의 자료는 2019년 5월에서 6월까지 수집하였으며 J시내에 위치한 간호대학생 3학년을 대상으로 수행되었다. 간호 대학생 75명을 실험군 37명과 대조군 38명으로 구성하였다. 수집된 자료는 ��2-test, independent t-test와 paired-test를 통해 분석하였다. 분석결과 단순도뇨 자신감(t=4.60, p<.001)과 단순도뇨 술기능력(t=3.46, p=.001)에서 유의한 효과가 있는 것으로 나타났다. 하지만 사례기반 교육이 간호대학생의 단순도뇨 지식에서는 유의하지 못한 것으로 나타났다. 배뇨곤란 사례기반 교육은 단순도뇨 자신감, 단순도뇨 술기능력 향상에 효과적인 교육 중재로 사용될 수 있을 것이지만 단순도뇨 지식에서는 추가적인 연구를 통하여 교육의 효과에 대한 검증이 필요할 것이다.
