This paper proposes a fatigue recognition method using the C4.5 algorithm. Based on domestic and international studies on fatigue evaluation, we have completed the fatigue self - assessment scale in combination with lifestyle and cultural characteristics of Chinese people. The scales used in the text were applied to 58 sub items and were used to assess the type and extent of fatigue. These items fall into four categories that measure physical fatigue, mental fatigue, personal habits, and fatigue outcomes. The purpose of this study is to analyze the leading causes of fatigue formation and to recognize the degree of fatigue, thereby increasing the personal interest in fatigue and reducing the risk of cerebrovascular disease due to excessive fatigue. The recognition rate of the fatigue recognition system using the C4.5 algorithm was 85% on average, confirming the usefulness of this proposal.

The purpose of this study is to investigate the current service pattern of electronic scholarly journals at homepages of Korean academic societies and to provide some suggestions for the better service of electronic scholarly journals. Data were collected from December 26, 2003 to January 6, 2004. The object of the examination was from the number of 257 academic societies which are publishing Registered Journals designated by Korea Research Foundation. Among the number of 257 academic societies, 116(45.1%) of them are providing electronic scholarly journals at their homepages, and among the number of 116 academic societies, 62(53.4%) of which are providing electronic scholarly journals with their own efforts without other organizations' help. The number of 257, 116, and 62 academic societies are compared with national information circulation institutions in terms of the service of electronic scholarly journals. Suggestions for the better service of electronic scholarly journals at academic societies in Korea are also provided.

The purpose of this study was to investigate students' and parents' perceptions of nutrition education. In this survey, 7,577 elementary school students and 6,003 of their parents across the country were surveyed about the necessity of implementing nutrition education, its present status and problems and future methods for nutrition education implementation. The results showed that 96.6% of the parents and 62.8% of the students responded that nutrition education was urgently needed, at least once per week in the lower grades of elementary school, and that it should be related to and coordinated with special activities class. In addition, the survey showed that students and their parents wanted nutrition teachers to establish a nutrition counseling room, a practical cooking class, a special activity class, and/or dietary camp during school breaks. With regard to the status of nutrition education at home, there was statistical evidence that suggests significant differences between urban and rural schools. Approximately 63% of the parents indicated that they had difficulty teaching nutrition education in their own homes, because it was difficult to determine the dietary habits and nutritional status of their children. When asked about attending a dietary class for parents, 74% expressed their intent to attend. Parents were most interested in learning about cooking practices, diet therapy, and food information in that order. The results showed that the most effective method of dietary education was to teach appropriate nutritional practices in school and at home simultaneously. Hence, necessary information and education should be provided through special lectures, special cooking classes, and dietary classes for parents. The conclusions of this study suggest that a variety of education programs should be developed to achieve effective nutrition education for students and their parents.

정보자원의 변화에 따라 학습의 유형도 점차 변화되고 있으며 그에 따라서 컴퓨터를 이용하는 학습 형태도 변화할 필요가 있다. 그것은 학생이 중심이 되는 학습형태이며 그 중의 하나가 문제해결학습형태이다. 컴퓨터와 정보통신기술을 이용하는 문제해결능력은 구체적인 수준에서의 컴퓨터 관련 지식과 기술에 대한 체계적인 조직이 필요하다. 본 연구에서는 정보소양의 단계를 문제인식, 전략수립, 정보수집, 정보가공, 정보출력, 반성단계로 제시하고 그에 따른 컴퓨터관련 지식과 기술을 조직하여 문제해결능력 신장을 위한 컴퓨터 교육과정의 한 모델을 제시하였다.Abstract Learning styles have got to vary gradually according to the change of information resources. Thus We need to change learning styles with a computer. It's a student-oriented learning types. One of them is called a problem solving learning type. The problem solving ability with a computer and information communication technology require the systematic organization of concrete knowledges and the technology about computer. In this study we found the steps of information literacy as problem cognition, strategies establish, information collection, information processing, information presentation, reflection and proposed a model of computer curriculum to improve the problem solving ability.

The purpose of this study is to examine the factors that influence the risk perception of reality on social media. Specifically, we analyzed how exposure to risk issues through media and bridging/bonding social capital influence social and personal risk perception. Here, we categorized risk issues into infectious diseases, sex crimes, and radioactive contamination. Findings are as follows. The effect that the type of media and social capital have on risk perception vary depending on the risk issues. Regarding issues of disease and radiation, bridging social capital had a positive effect on social risk perception whereas bonding social capital had a negative effect on personal risk perception. In the case of sex crimes, bonding social capital affected both social and personal risk perception negatively, and an interaction effect between exposures and social capital could be found. The significance of this study is that it considers both media variables from previous studies and social capital variables essential to social media studies and combines the two in order to study the factors that influence risk perception.

This paper tests whether there are any differences in perceived effectiveness according to the range of outsourcing, and we tried to identify the reasons if any. By executing a field survey and T-test on composite success measure value of two types (integrated outsourcing type and backend outsourcing type), we testified that the perceived effectiveness of the two types in outsourcing was not different. Discussion fo the stududy result followed. First, 'integrated outsourcing type' does not generate very excellent performance. Second, so far the characteristics of 'integrated outsourcing type' such as strategic management of IS, activating end-user computing(EUC), and making the strategic partnership with vendors and so on have not been successfully utilized as expected.
