The purpose of this investigation was to determine the effects of low intensity circuit weight training on physiological variables such as body composition, blood lipid profile and cardiopulmonary function in obese middle school girls. Thirty obese middle school girls (%fat>25%) were divided low intensity into weight training (CWT; n=10), aerobic training(AeT; n=10), and control(CTL; n=10) groups. The participants in the training groups had trained 50 min each day three times pre week for 10 weeks. The results were summarized as the follows: 1.Anthropometry and body composition The height(P<.01) increased significantly. Although the body weight did not show statistically significant changes, it decreased. W/H decreased 11.34%, even though it was not statistically significant increase in LBM. After the 10-week training, there were no significant differences between the CWT and AeT groups in all the variables related to body composition. 2.Blood lipid profile There was a significant decreases in all blood lipid profile. With 10-week training, there was significant difference in TC and TG between the CWT and CTL groups, However, there were no significant difference between the CWT and AeT groups in all the blood lipid profiles. 3.Cardiopulmonary function There was a significant increase in VO2max/kg. There were significant differences between the CWT and CTL groups in VO2max/kg and VO2max/LBM. However there were no significant differences between the CWT and AeT groups. HRrest and Hrmax did not change signicantly. With 10-week training, did not result in significant difference between the groups in all the cardiopulmonary function variables

This paper presents a design and implementation of a distributed audio/video stream services based on CORBA distributed objects and JMF(Java Media Frameworks). Our design abstracts software components concerning the processing of audio/video streams as distributed objects. And we separate the transmission path of control data and media data for efficient stream transfer. CORBA RPC calls are used as control signals such as connection establishment, call control, device control. But media streams are transmitted by a RTP(Realtime Transport Protocol) directly. Distributed objects are designed by IDL(Interface Definition Language) and implemented using Java and various JMF components. We show a connection establishment and flow control procedure of streams. And we introduce an implementation environments and evaluate a performance.

Injection molding technique is directly related to high quality, low cost which customer needs. Injection molding process is very importantly dealt with the sharp increase of resin consumption and so is studied very actively nowadays. The influential factors to injection molding parts are material melting temperature, mold temperature, injection speed, injection pressure melting temperature are especially important. The boundary and contents of research and development are design injection molding making test specimen of KS rules, manufacturing injection mold, injection varied on mold temperature, injection pressure and melting temperature, mechanical properties injection test specimen, and analysis of test. In this study the specimen for tensile and impact strength tests were made under various cylinder and mold temperatures. Measurements were done to find optimum region of mechanical strength through the tests. And me found that mechanical strength decrease by increasing mold temperature and decreasing melting temperature. Therefore if the molding process is done under the optimum injection characteristics of resin for the final parts can by optimized as well as formability.

The athletic high-school was established to discover young players having good character early, bring them up to good players by scientific training program and related guide, to develope athletics of local society and enhance national glory finally(1982, Department of Sports). The capacity of energy-consuming is an element that decides athletic ability. Adoption of large-energy is caused to growing corpulent, so athletic ability is decreased. Also adoption of little-energy becomes stoppage-factor of training. If that is so, this research produces several conclusions and opinions to provide an athlete, especially students of athletic high-school, with a criterion of nutrition-supply. (The object of this research is students of K-athletic high-school ) 1)All capacity of energy-adoption per a day is 4349±513kcal, capacity of energy-adaption per a kilogram is 60.24±7 kcal. 2)All capacity of energy-consuming per a day is 4553±491 kcal, capacity of energy consuming per a kilogram is 63.81±14 kcal. 3)The time, students consumes energy most, is in exercise. At this time, the capacity of energy-consuming is 2084±613kcal. 4)The average of the HR per a day is 73 per a minute. When students take exercise, HR is 107 per a minute and is fastest. 5)The relation between 'all capacity of energy-adoption per a day' and 'all capacity of energy-consuming per a day', namely energy-balance, is 0.959. The result shows (-). This result means 'all capacity of energy-consuming per a day' is more than 'all capacity of energy-adoption per a day', but it is difficult to say "this result is energy-unbalance." These are several opinions, based on above conclusions, about the nutrition-condition of K-athletic high-school students. 1)'All capacity of energy-consuming per a day' is more than 'all capacity of energy-adoption per a day', but it is possible to say "Nutrition-balance of K-athletic high-school students is normal." 2)So, students have to adopt more, 10% of 'all capacity of energy-consuming per a day'. The reason is that students of K-athletic high-school are in growth period, so students need capacity of energy-adopting used in order to grow up, only so students is in nutrition- balance. 3)I think that 'The proper capacity of energy-adoption per a day' of K-athletic high-school students is 'all capacity of energy-adoption per a day', 4349±513kcal, and 10% of 'all capacity of energy-adoption per a day', RDA is 5000 kcal. (but, this is not applicable to all sports.) 4)The capacity of energy-consuming in this research is more than preceding research This result means the exercise of students of K-athletic high-school is too much.

This study was taken their weight and measured eight and measured kinds of physical fitness for the study intended for fourteen weight lifters in Kangwon Physical High School. The measure had been carried for ten days before the game. We have also measured the physical fitness while reducing their weight for two days. We compared the result after the loss in weight with that of before. As a result, we have the conclusion as follow 1. According to the statistics, there was no significant difference in muscular fitness (sit- up, back muscular strength, vertical arm pull test) between the two results. 2. There was no significant difference in leg muscula power (sarjent jump) statistically. 3. There was no significant difference in muscula endurance (handstand push-up, pull squat). 4. Statistically, we had no significant difference in agility (side-step) 5. The appropriate weight for lifters is about two kilograms lower than usual. Two kilograms mean about three percent of his own weight. As mentioned above, we can see that the method, the degree and the period of the loss in weight don't influence the physical strength for weight lifters. Therefore, they need to keep their weight proper all the time within the limit of around two kilo-grams of weight limits.

The purpose of this study was to examine effects of adolescents' life styles, such as sleeping and meal patterns, on their arousal level in school. The experiment was conducted on a sample of 253 male students, 202 first graders and 51 third graders in junior high schools. The Korean edition of "A self assessment questionnaire to determine morningness-eveningness," originally prepared by Horne and Ostberg, was used to judge the morningness or the eveningness of the students. In order to check the validity of the questionnaire, the students' body temperatures from 7 : 00 a. m. to 12 : 00 p. m were taken, and the presence of a difference in fluctuations of the body temperatures between the morningness group and the eveningness group was confirmed. Their life style were surveyed using a our-own made questionnaire, while their arousal levels were measured by the Flicker test. Between the morningness group and the eveningness group, their are statistically significant differences in the patterns of rising (P<0.05), the appetite in the morning (P<0.05), and physical and mental conditions (P<0.01), Especially, the morningness group shows a significantly higher arousal level during schooltime from 9 : 00 a. m. to 4 : 00 p. m. than the eveningness group. Comparison of life styles of the groups shows that students in the eveningness group the tendencies to stay up till late, get up without recovering from their fatigue, and suffer from loss of appetite when they begin their daily work in the morning. Further, since the eveningness group shows a much lower arousal level in school than the morningness group, it seems that a special care should be paid to the former group not only for the enhancement of the efficiency in their learning but for prevention of various possible accidents. As a results, persistent and good guidance is required to lead adolescents to a sound life style.
