The purpose and content of Chonnam National University Center for Science Talented Education program and students' responses were described. The program was developed with the purpose of providing various learning opportunities for science talented students according to the level of their learning abilities. Students are given a variety of activities based on their potentials and interest. The program was developed in four subjects, such as mathematics, information science, science Ⅰ (physics and earth science), and science Ⅱ (biology and chemistry). Each subject consisted of simple inquiry, advanced one, and project, even though it had its own distinctions. Students were selected for each subject based on two criteria, that is, achievements in school science or mathematics (the upper 3 percent of the 8th grade students) and examination scores. Means and standard deviations for each subject were as follows: 51.8 and 13.3 for Science Ⅰ, 53.1 and 13.9 for Science Ⅱ, 36.7 and 10.7 for mathematics and 36.4 and 12.5 for information science. Thirty hours of summer classes were performed, and a survey was administered to obtain students' responses concerning difficulty, interest, teaching and content of the program. They gave relatively favourable responses in most area, but lack of time for studying was revealed in mathematics and information science. Further study in needed to get detailed and more accurate results of our program.

Purpose : The aim of this study was to clarify the lung capacity, maximal insufflation capacity, and peak cough flow when a mechanical insufflation-exsufflation(MIE) method was used to increase Duchenne muscular dystrophy patients' lung function. Methods : The subjects of the study were 21 patients with Duchenne muscular dystrophy. They were randomly selected from patients within the boundaries of the selection criteria, and divided into two groups; The subject group(n=11) used the mechanical insufflation-exsufflation method with traditional therapeutic exercise. The control group(n=10) used only traditional therapeutic exercise. Results :The results indicated that maximal insufflation capacity, unassisted peak cough flow and assisted peak cough flow significantly increased in the subject group(p<.05). By contrast, in the control group, the results didn't indicate the significant differences from the variable. There were significant differences in maximal insufflation capacity and assisted peak cough flow between the subject group and the control group before and after the application of the mechanical insufflation-exsufflation method. Conclusion : A mechanical insufflation-exsufflation method has positive effects on the improvements of cough functions and that of pulmonary functions such as lung volume, lung elasticity in patients with Duchenne muscular dystrophy.

This study proposes a lower-limb exoskeleton system that is controlled by a wearer's muscle activity. This system is designed by following procedure. First, analyze the muscle activation patterns of human leg while walking. Second, select the adequate actuator to support the human walking based on calculation of required force of knee joint for step walking. Third, unit type knee and ankle orthotics are integrated with selected actuator. Finally, using this knee-assistive system (KAS) and developed muscle stiffness sensors (MSS), the muscle activity pattern of the subject is analyzed while he is walking on the stair. This study proposes an operating algorithm of KAS based on command signal of MSS which is generated by motion intent of human. A healthy and normal subject walked while wearing the developed powered-knee exoskeleton on his/her knees, and measured effectively assisted plantar flexor strength of the subject's knees and those neighboring muscles. Finally, capabilities and feasibility of the KAS are evaluated by testing the adapted motor pattern and the EMG signal variance while walking with exoskeleton. These results shows that developed exoskeleton which controlled by muscle activity could help human's walking acceptably.

Chirimen (silk crepe) has been one of Japan's most distinctive textiles since times and has gained a reputation worldwide as the supreme example of Japanese costume. It is because of its distinctive quality and features, transcending the history, lacation and lacal of the people who wear this form of clothing, that chirimen has continued to highly valued over a long historical period. There is a wide range of literature on the subject of chirimen written from the standpoints of introducing the various types of material, discussing its history, and looking at the origins of the textile unions. However, most such writings are little more than fragmentary attempts to describe these matters from an empirical and publicity-oriented position. Very little serious research has ever been published in this area. In the present study I examine the features of chirimen. I began by directly interviewing kimono wholesalers, kimono stores and Western-style clothing stores on the subject of chirimen in order to establish a clear image of this fabric. I then went on to examine the subject experimentally in terms of the physical properties of the fabric in connection with the features of this image. In the study of the physical properties of the material, I selected habutae as a silk fabric to offer comparisons with chirimen. Habutae is used frequently together with chirimen in garments such as semi-formal visiting kimono (homongi), kimono in non-color fabric (ironashiji), mouming kimono (mofuku), broad-sleeved kimono (tomesode and furisode), and undergarments such ad juban.

The CAI (Computer-Assisted Instruction) system for science teaching has been increasing both in quantity and in quality during the last two decades. However, science learning by computer has not played a leading role in the science teaching process. Therefore, the purpose of this study was to analyze the effectiveness of tutorial CAI programs according to the learner's characteristics such as sex, inquiry skills, attitudes toward science subject, logical thinking skills, achievement motivation, science content achievement in science teaching. One group pretest-posttest design was used as an experimental design. The three tutorial science CAI programs were used for thirty males and females selected in grade eight. According to the analysis of CAI achievement scores the female students showed significantly higher (P<0.05) than the male students. Also, one-way analysis of variance was used to investigate the effects of interaction between sex and achievement motivation. The significant difference on the effects of interaction between sex and achievement motivation has not found. The effects of tutorial CAI between logical thinking skills, attitudes toward science subject, inquiry skills, achievement motivation, science content achievement according to upper and lower levels were investigated by using the statistical analysis of one-way ANOVA. The results indicate that tutorial CAI might provides a good opportunities for the improvement of science achievement to the lower level students of attitudes toward science subject, inquiry skills, science content achievement.

Korean civil and environmental organizations had selected and announced ‘The top ten pieces of news in the environmental field of the year’ on Dec. 2, 1999. This study investigated the possibilities that these could be used as subject matters of environmental curriculum and infused into the environmental textbook of secondary schools, referring to documents and internet materials. The top ten pieces of environmental news could be clarified as controversial topics. The locality was analyzed that 2 pieces occurred mainly in a specific area, 4 pieces in several areas and 4 pieces around all over the country. Most of them had the opposing partners as the federal and local governmental vs. civil organizations and people. Each of them could be used as subject matters for 7 to 13 contents domains of the 6th and 7th Korean environmental curriculum. The knowledge of most of them had related counterpart concepts to be infused into the ‘Environmental Science’textbook for the high school students. The results suggested that more concerns and efforts are needed to deal and use these controversial issues as real world problems of Korea in the environmental education practices
