From february 20th, 1988 to May 10th 1989, I examined into the caloric intuke, living contents phsicail strenght, physique subcutaneous fat and capacity of exercise in 56 girl middle school gymnasts representing their cities. Especially, correlations of physique, physical strength and subcutaneous fat with power of exercise were af followings. A. The twirl gymnast's average age was about 14.4 years old and have exercised for about 5.2 years. B. When exercising, they took about 1933, 1 Kcal a day but when participating in games, they took 1,500 Kcal a day C. The average height was 148.8cm and the tallest ones were I-ree girl middle school gymnasts and their heights averaged 151.4 Centimeters. The weight averaged 38.1 Kilograms. The highest figures in weigh, the circumference of chest, and sitting height were 39.9 Kilograms, 76.0 Centimeter, 83.0 Centimeters respectively and all these highest figures were applied to I-ree girl middle school gymnast's. D. Subcutaneous fat averaged 12.55mm and the maximum subcutaneous fat was 16.4mm in Chun Cheon girl middle school gymnast's. In the case of muscular strongest ones were Chun -Cheon girl middle shcool gymnast's and their record was 37.6kg in total. In the case of long-hanging, Soo-yu girl middle school gymnast's recorede 43.4 seconds, in Buppe test, Won - Wha twirl middle school gymnast's 8.4 times, in forward flexibility, I-ree girl middle school gymnasts recorded 27.2 Centimeters, and backward flexibility, Won Wha girl middle school gymnasts recorder 64.3 Centimeters and each record represented the highest bevel. E. In vertical jump, Soo-yu girl middle school gymnasts recorded 45.8 Centimeters, in long broad jump, Chun-Cheon girl middle school gymnasts recorded 433.8 Centimeters. Each record was the highest level. In kinetic balance test, Chun-Cheon girl middle school gymnasts showed hight stability. In still balance test, Soo-yu girl middle school gymnasts showed stable balance. F. There were reliable or high correlationship between energy and hight, energy and weight as the carolic intake increased but there were no correlationships between energy and endurance power, energy and balance and energy and vertical jump. The conculsions above were based on gymnast's the 10 day carolie intakes when exercising and the 5 day carolie intakes when participating in games.

Plastic microlenses play an important role in reducing the size, weight, and the cost of the systems in the fields of optical data storage and optical communication. In the present study, plastic microlens arrays were fabricated using micro-compression molding process. The design and fabrication procedures for mold insert were simplified by using silicon instead of metal. A simple but effective micro compression molding process, which uses polymer powder, were developed for microlens fabrication. The governing process parameters were temperature and pressure histories and the micromolding process was controlled such that the various defects developing during molding process were minimized. The radius and magnification ratio of the fabricated microlens were 125$\mu\textrm{m}$ and over 3.0, respectively.

This investigation is based on the questionnaires answered by 300 people who are the members of 10 private enterprise tennis courts in Chung-nam. The aim of this investigation is to know whether tennis could be a high recommendable one as a social sports and what favorable effects could be produced by playing tennis. And I could obtain the following results. 1. Members : Those who answered the questionnaires, 247 of them 82.3% almost are the thirties or the forties in a middle age. And 207 of them 69.0% are the salaried classed-public servants, teachers, and company employee who make use of their spare times. 279 of them 93.0% belong to the higher or middle classes in the standard of living. 2. Causes : They play tennis not only to take card of their health but also to do for mere pleasure and associate with other persons. 3. Career, Time : 157 of them 52.3% have the experiences of playing tennis for two or five years. 201 of them 67.0% usually play tennis from a.m. 6 to a.m. 8 and play it 1 or 2 hours a day. 4. Frequency : 190 of them 63.3% play tennis twice or fifth in a week. 191 of them 63.6% began to play it in spring or fall. 5. Injury : 38 of them 12.7% have got injured but 220 of them 73.3% said they would play tennis. So we can say tennis has favorable effects more than injured factors. Regardless of age the following results are got by the effects' comparison - if after playing tennis has better effects than before play tennis or not. 6. Biological effects : They said playing tennis is good health in breath, sleeping, digestion. 7. Physical effects : 204 of them 68.0% have promoted their health and controlled their weight through playing tennis and have experienced the favorable results such as removal of fatigue and increase physical strength. 8. Psychological effects : 175 of them 58.4% said that they have enjoyed their life and found their lives worth living and had increased endurance and self-confidence and decrease anxiety in a working place. 9. Effects in family life : Some of them have suffered from financial difficulties and discontent of their family resulting from neglect of their homes but most of them could create pleasant astomosphere in their homes. 10. Social effects : 219 of them 73.0% said that have known a lot of people during playing tennis and so they have got along with the others. From the above results, I have come to the conclusions that tennis is a good sport which has good effects in physical, psychological, and domestic lives. So I hope that those people who have never played tennis would be able to a take part in playing tennis and they could enjoy good healths and happiness by playing tennis.
