The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

In this study, I compare and analyze the difference of recognition between 97 teachers and 107 parents in actual condition of management, appreciation, curriculum, the direction of development about child physical education in child physical education institute through questionnaire attached appendix 1,2 The result from analyzing the questionnaire is following First, though both parents and teachers understand the need and appreciation of child physical education, there is a significant difference in that teachers are more understanding. It is appeared that both of them think that child physical education is needed for harmonious physical and mental development. Secondly the contents that teachers think the most important to be taught in child physical education is to percept and move body and the contents that parents think the most important is to participate in physical activities. The large number think to percept and move body there is a significant difference among them. Child physical educations which are often lack of creative education and basic movements are needed to be planed by both child educators and child physical educators, who discuss and work together as an expert to make a better program. To make child physical education continue to lifelong education, various programs based on developmental physical education program should be developed and institution for child physical educators should be made.

Early repolarization is a common electrocardiographic (ECG) feature found in young adults, men and athletes, and has been considered to be a benign feature for the last several decades. But recent studies suggest that early repolarization may be related to idiopathic ventricular fibrillation and sudden cardiac death. We report a young man, 35 years old, who had life threatening ventricular fibrillation and sudden cardiac arrest. He was evaluated for cardiac causes of ventricular fibrillation. There was no explanation other than that his ECG showed an early repolarization pattern so we treated him with implantable cardioverter defibrillator. Thus, we suggest that early repolarization may be related with life threatening ventricular arrhythmia.

The feasibility using an isolate derived from the enriched microbial consortium for explosive degradation was explored. The present study reports on the isolate which was developed to grow aerobically with RDX (hesahydro-1,3,5-trinitro-1,3,5-triazine) as the sole sources of carbon and nitrogen. Complete depletion of RDX a the initial concentration of 15 mg per liter was achieved within 24 days of incubation in bench-scale bioreactors. Addition of supplemental carbons (e.g., succinate, glucose, fructose) stimulated the degradation of RDX. The isolate also could degrade structurally related explosive 2,4,6-trinitrotoluene. Degradation of RDX was verified by HPLC analysis of the residual RDX concentration in the test culture. Microscopic examination of this degrader, HK-6 revealed a Gram-negative and coccobacillus shaped cell. Strain HK-6 was characterized by using the Biolog system and an analysis of the total cellular fatty acids. The strain indicated that the bacterium could be identified and designated as pseudomonas putida HK-6

To examine the change of blood lactate concentration, EMG power spectrum, and Torque during fatiguing isokinetic contraction and recovery phrase, 6 sprinters performed maximal isokinetic knee extension at angular velocity of 3.14 rad.sec??(180°sec??) to 75% decreasing point (25%PT) using CybexⅡ system. In exercise phase, there was significant correlation between the decrement of peak EMG and median frequency and that of torque, and decrement of torque was greater than that of EMG . In recovery phase, EMG was restituded as normal value rapidly in a minute, but torque was restituded more slowly, and blood lactate concentration increased gradually from 50%PT to 3 minute after recovery. As a result of this study, it is suggested that muscle fatique due to decreasing of metabolic substrate and accumulation of metabolic products in peripheral site of muscle, and that inhibitory factors act neuromuscular junction in the end of exercise from rapid restitution of EMG in recovery phase.
