The HANARO, a multi-purpose research reactor of 30 MWth open-tank-in-pool type, has been under normal operation since its initial criticality In February, 1995. Many experiments should be safely performed to activate the utilization of the HANARO. A flow simulation facility is being developed for the endurance test of reactivity control units for extended life times and the verification of structural integrity of those experimental facilities prior to loading in the HANARO. This test facility is composed of three major parts; a half-core structure assembly, flow circulation system and support system. The flow circulation system is composed of a circulation pump, a core flow pipe, a core bypass flow pipe and instruments. The system is to be filled with de-mineralized water and the flow should be met the design flow to simulate similar flow characteristics in the core channel of the half-core test facility to the HANARO. This paper, therefore, describes an analytical analysis to study the flow behavior of the system. The computational flow analysis has been performed for the verification of system pressure variation through the three-dimensional analysis program with standard k-$\epsilon$ turbulence model and for the verification of the structural piping integrity through the finite element method. The results of the analysis are satisfied the design requirements and structural piping integrity of flow circulation system.

The purpose of this study was to analyze the kinetic factors of the golf driver swing using the Inverse Dynamics function. For this purpose, joint force were calculated. In order to test the possibility of Inverse Dynamics function(motion-dependent interaction), a triple segmental system was set for wrist, left shoulder and lumbar and joint force working on the anatomical joint region was estimated. For this study, 7 professional golfers were sampled, and then, their driver swings were recorded with two high-speed digital video cameras (180 frames/sec.) to be synthesized into 3-dimensional images and coordinated. Then, Eular's equation was used to produce some kinematic data, which were used to calculate joint force and torque with Newton's function. All data were calculated using LabVIEW 6.1 graphic program. The results of this study can be summarized as follows; It was found that the joint force was generated on wrist, shoulder and lumbar joints in the direction of the target, and that the joint force was stronger in the direction of target immediately before impact. The joint force was generated towards the target to activate the nodes, and then, it was generated in the reverse direction to increase the speed during impact.

Purpose: The aim of this study was to investigate prevalence and ecological characteristics of excessive television viewing among elementary school students in Seoul. Methods: Secondary data, representative sample of 11,082 subjects in Seoul was used. After prevalence of the excessive television viewing was identified by using factor analysis, 6 main factors explaining the ecological indicators was founded. After identifying prevalence of the excessive television viewing, by using factor analysis, we found 6 main factors explaining the ecological indicators. After categorizing factors into socio-psychological and lifestyle characteristics, we were investigated the odds ratio of excessive television viewing per characteristics by using multiple logistic regression. Results: The prevalence of excessive television viewing was 29.7% among the elementary school student in Seoul. The prevalence were higher in male, higher grade, and non-South of the Han River. Socio-psychological indicators which expressed excessive television viewing were annoying or bullying, scolding from teacher, depressed mode, thought for a runaway from home, an experience of diet, and negative body image. Life style indicators were a lower intake of fruit and vegetables, a higher intake of Ramyun and soft drink, a worse life style of hand washing, and wearing safety equipment. Conclusion: Lifestyle of television viewing was the comprehensive results from family, school, and society rather than a personal preference. Therefore, it is necessary to educate the hazard of excessive television viewing, to reenforce the students' health competence, to activate a safe leisure program as an alternate of television viewing, and to develop a recommendation.

Purpose: This study was to investigate the effects of health education on health knowledge and health promoting behaviors in elementary school students. Methods: 17 sessions of health education were provided to the fifth graders in two elementary schools in Gyunggi Province and data were collected from 268 students. The data of 250 students who had responded both pretest and posttest were analyzed using SPSS program. Results: The scores of health knowledge for mental health, social health, sex and health were lower than other domain. The scores of knowledge for drug abuse/smoking and disease prevention/management were higher than other domain. Overall health knowledge was improved significantly from 0.60 at pretest to 0.81 at posttest (t=15.98, p<.001). The score of health promoting behaviors at post test was higher than score at pre test but this change was not significant (t=-0.91, p<.365). Conclusion: Health education had significant effects on health knowledge and we need to maintain and activate health education in elementary schools. Health education did not have significant effects on health promoting behaviors, we need to do further research for understanding why and how we improve health promoting behaviors.

공공도서관의 독서회 운영은 독서활동을 활성화하는데 중요한 역할을 하기 때문에 독서회 발전과정을 살펴보기 위하여 그 동안 독서회 운영에 관한 실태조사를 1991년 1999년 2번 실시했었는데 2004년에 3번째 실시하여 그 결과를 서로 비교 분석했다. 공공도서관의 개관은 처음 실태를 조사할 때보다 배로 증가하였으며, 독서회운영에도 많은 관심을 보여 공공도서관의 독서활동을 활성화되고 있는데, 공공도서관 자체에서 독서회를 조직하여 운영하는 현상이 아주 적극적으로 나타났으며, 운영 예산도 많이 확보하고, 독서활동 장소도 적극적으로 제공해 주고 있다. 그러나 독서활동 프로그램의 개발과 독서회 운영 전담 전문가의 배치는 여전히 독서회 운영의 과제로 남아 있다.

The purpose of this study was to survey on the awareness of teachers and students to mass media as a source for school environmental education. This study was performed with the questionnaire to 179 teachers who participated in certificate in-service training for $\ulcorner$Environment$\lrcorner$subject and to 635 students(primary: 177, middle: 179, high school students: 279). The results derived from this study were as follows: First, most teachers(86.6%) evaluated that mass media's effects on students were high and positive in terms of school environmental education, thus they thought that the application necessity and possibility of mass media for environmental education were so too. Second, many teachers evaluated that more program related with environment had to be produced(57.0%) and disseminated, and information on them had to be apprised teachers to activate school environmental education(44.1%). Third, both teachers(87.1%) and students(70.4%) evaluated that audio-visual media such as television, video, movie was better than others for environmental education because audio-visual media could be more realistic and dynamic(T: 48.0%, S: 41.7%). Fourth, we found that as the result of statistical analysis, students's friendliness. credibility and preference on media were different to school classes. But we could not analize the relationship between factors for the limit of sample.

The purpose of this case study was to introduce a myoelectric hand prosthesis for upper extremity amputee and prosthetic training program. Limb loss can result from disease, injury, or congenital causes. Trauma has been increasingly important role as the cause of amputaion in young, vigorous, and otherwise healthy individuals. The higher the level of amputation the greater the functional loss of the part, and the more the amputee must depend on the prostheis for fuction and cosmesis. Myoelectrical control of prostheses is a recent development and has been steadily gaining in clinical use over the past 20 years. Such a prosthesis uses signals from muscle contraction within the stump to activate a battery driven moter that operates specific component fuctions of the prosthesis. This twenty years old male case was operated a right above-elbow amputation due to tracffic accident and admitted to Yonsei Rehabilitaion hospital for the preprosthetic and prosthetic training. The case was able to successfully complete his myoelectric hand prosthesis training in the February of 1995.
