The purpose of this study was to see if a relationship existed between the level of modesty in clothing ana clothing values of male and female university students. The difference between sex was also investigated. A questionnaire composed of Engelbrecht's 'Modesty in relation to women's dress' and Creekmore's 'Measure of eight clothing values' was administerd to 1, 100 students and the data from 888 respondents (466 male, 422 female) was analyzed by t-tests. findings were as follows : 1. There was no significant difference between male and female in the level of modesty in clothing. 2. Each score of sensory, economic. social, theoretical, and religious clothing value of male students was significantly high and exploratory, aesthetic and politicalclothing value score of female students was significantly high at the .005 level of confidence. 3. Each score of sensory economic, theoretical and religious clothing value was significantly high in Modest group and exploratory, aesthetic and political clothing value in Immodest group was significantly high at .005 level of confidence.

The purpose of this study was to examine the peer acceptance of children as a function of children's behavioral traits, mother- and father- child attachment and family-related variables. The sample was consisted of 224 5th grade children from elementary school in Kwang-ju. Data were gathered through questionnaires of peer acceptance, behavioral assessment, mother- and father-child attachment, and family- related variable. The results show that the children's behavioral traits, mother-child attachment, and the sibling's being has the significant differences on the peer acceptance of children. Among these variables, prosocial behavior was the most significnat variable.

This paper describes on the development of power monitoring system using microprocessor. The detecting power system is composed of main controller system and analyzing software. The system detected voltage, current temperature, leakage current and its saved in ROM. This system applies the 'AT89C52' to CPU and 'AM29F040B' used a memory to save the data.

A conventional UPS can supply the clean power to the load. However, it may generate input current harmonics and the input power factor can be very poor. Therefore, the UPS itself may be a power interruption. This paper provides multifunctional converter of using single phase UPS. The proposed UPS can supply the clean power to the load without polluting the mains power system. The multi-functional converter provides battery charging, var compensation and harmonic suppression simultaneously. It was simulated to verify this work.

This study was undertaken to assess the school flood service management and its perception by dietitians. Questionnaries were developed and answered by 162 dietitians in elementary schools in Chollanam-do. The duration of the flood service system was the longest in remote areas followed by rural and urban areas. The average number of persons served a day was 680 per dietitians. More than three schools were supervised by 52.4% of dietitians. Lack of facilities, including restrooms for the flood service personnel and storage compartments for convenience products were indicated. Regardless of the type of school flood service system, the dietitians pointed out that they urgency needed gas fryers, gas griddles and vegetable cutters, which would be helpful in preparing fried flood for the students. Despite the dietitians' eagerness to teach nutritional education, 80.9% of the respondents did not provide nutritional education to the students, because of the lack of class roomtime. It was suggested that the teaching nutritional education by dietitians was desperately needed for the improvement of health and the nutritional status of school children.

Purpose: The study evaluated the effects of a fall prevention program in a Korean rural area. Methods: A single pretest-posttest design group was studied. Thirty nine residents in the same rural area participated in a program comprised of education and exercise. The 5-week fall prevention program was performed for 60 minutes, once a week. Results: Fall Efficacy Scale (FES) score and Activities-specific of Balance Confidence Scale (ABC) score were significantly increased after the program, but the pre-and posttest FES and ABS scores were not significantly different between the fall experience group and non-fall experience group. Conclusion: The fall prevention program can improve rural residents' FES and ABS, and is recommended as a fall prevention intervention.

A photovoltaic panel is a device that, through the photovoltaic effect, converts luminous energy into electric energy. Photovoltaic generation system uses infinity of solar energy, cost of fuel is needless and there is no all pollution or waste occurrence. This paper summarizes the results of these efforts by offering a photovoltaic system structure in 50kW large scale applications installed In Chosun University dormitory roof. The status of PV system components, are inter-connection and safety equipment monitoring system will be summarized as this article. This describes configuration of utility interactive photovoltaic system which generated power supply for dormitory In this paper represent 50kw utility PV system examination result

The major part of SMES (Superconducting Magnetic Energy Storage) system consist of the superconducting coil, cryostat and current lead, power converter. The 0.7MJ SMES coil was a design and manufacture by using SMES device that we developed a design code. A SMES coil was wound with high winding tension in order to prevent wire motion from Lorentz force. This paper described optimum design for the SMES coil.

We are developing a small-sized superconducting magnetic energy storage ($\mu$ SMES) magnet with the storage capacity of a few megajoules, which provides electric power with high quality to sensitive electric loads. As the earlier step of the fabrication of the $\mu$ SMES magnet, this paper describes recovery current experimental results of a kA class superconductor. Recovery current of a superconductor was tested in two points of copper ratio and cooling effect.
