This study analyzed the comparative effect of Cooper exercise and continuous aerobic exercise for 10-12-year-old children with obesity for 60 minutes daily, three times a week for 12 weeks. The selected research participants were 76 children consisted of 54 boys and 22 girls with the %fat rate over 30% and were checked for the BMI, and %fat for the obesity index and blood lipid component for TC, TG, HDL-C, LDL-C and TC/HDL before and after the program, A 12-minute running was exercised for cardiorespiratory endurance, The intensity level of HRmax 55%-65% with the Karvonen formula measured the target heart rate for the exercise, The continuous aerobic exercise was performed for 40 minutes during the main exercise, and Cooper exercise was carried out by having the research participants carry a sand bag weighing 5% of theft body weight, A two-minute dynamic break was allowed after every 12-minute exercise. The repetitive measurement value for the pre- and post-programs was analyzed for the changing factors among the groups by using the comparative t-test analysis. A significant decrease occurred between the two groups as the result of the exercise program, weight, changes in the rate of the body formation for obesity; however, no statistical significance was resulted among different exercises, Further, the LBM was increased for every group but no statistical significance was supported, All the comparative groups showed a significant increase; however, the LBM was not significantly increased according to the statistics. The change in the blood lipid component significantly decreased for both groups; but it was significantly increased for the HDL-C, For the case of the comparative group, a significant increase was resulted; while a significant drop was evidenced for the HDL-C. For the change in the cardiorespiratory endurance, statistically significant increase was observed for the continuous exercise group and the Cooper exercise group while the comparative group showed no meaningful changes. As a result, an exercise program can significantly improve the changing factors for body shape and body formation of the children with obesity, and effectively play a role for the diseases related to arteriosclerosis and coronary heart disease. No significant difference between the two exercise groups entails a necessity for a long-term program when designing an exercise program for children with obesity, rather than a short-term program according to nutrient supply and exercise mode considering the fact that they are children in grow.

張訓梓 大韓法醫學會 1989 대한법의학회지 Vol.13 No.1

Extracts of ground seeds of Korean Celosia argentea L. were prepared in the usual manner, thereafter the agglutination tests with washed red blood cells and whole blood wee carried out. As a result, author demonstrated that washed red blood cells were markedly agglutinated by C. argentea L. extract, while whole blood was agglutinated in a small number. In the first experiment on a series of 291 blood specimen, washed red blood cells were agglutinated 278 (95.53%), failed 13 (4.47%), while the whole blood was agglutinated 8 (2.75%), failed 283 (97.25%). Since such differences in reactivity were observed, agglutination inhibition test of Celosia extracts by human serum was performed and revealed that by the all sera of 12 of agglutination positive with whole blood, the agglutination of C. argentea L. extracts were completely inhibited, however 429 sera of agglutination negative with whole blood revealed that 414 (96.5%) was inhibitor and 15 (3.5%) was non-inhibitor.

The effects of Pre-exercise BCAA injection on amino acids levels and exercise performance. The subjects of present study were 10 university students. All subjects participated in VO₂ max test to calculate their 75% VO₂ max workload with BCAA injection and without BCAA injection. All exercise test were continued until subjects stopped because of fatigue. There were no big changes in the total exercise performance between BCAA injection experimental conditions. In the blood isoleucine, leucine, arginine, and phenylalanine concentration, there were no significant differences between BCAA injection experimental conditions(p>.05). The blood glutamate concentration was decreased following exercise, and end of exercise were a little bit increased. The blood alanine concentration was increased and there were significant differences at the end of exercise between BCAA injection experimental conditions(p<.05). The blood ammonia concentration was increased during exercise, but there were no significant differences between BCAA injection experimental conditions(p>.05). In this study, there was no positive effect of BCAA injection as a ergogenic aids and pre-exercise BCAA injection might be lead to premature fatigue.

This research has the purpose of finding out the cause of stress which is inflicted on the women soccer players belonging to girls' high schools and women's colleges, and examining the different methods of solving their stress. To turn out reliable calculations of average and standard deviation, I used the data collected through questionnaires which are answered by the total number of 266 women soccer players (188 high school players and 78 women's college players), which is followed by the conclusion reached with the t-test for statistical verification, Among the causes of stress imposed on soccer players of the women's high schools and colleges, the most stressful low-factor is the time when they are despised by the others, the least stressful factor is the problem with the other sex. The difference of the causes of stress classified by factors reveals that the athletics performance factor is the highest for both the groups of soccer players of women's high schools and colleges. The factor with the most meaningful difference between both the groups of women soccer players is before-competition factor (girls' high school: 2.49±.69; women's college: 2.27±.72), with the meaningful difference at the level of t=2.38 p <.018, and the rest of the factors don't make any meaningful difference. The low factor of the stress-solving method which soccer players of girls' high schools and women's colleges have chosen the most is thinking the matter over and over, the low factor chosen the least by them is depending on smoking and drinking, and the difference of stress-solving methode classified by factors demonstrates that the clarification of the causes of stress is the highest factor for both the groups of soccer players of girls' high schools and women's colleges. The factor with the most meaningful difference between both the groups of women soccer players is conversation factor (girls' high school: 2.06±.78; women's college: 1.79±.64), with the meaningful difference at the level of t=2.38, p <.006, and the physical factor is the next (girls' high school: 2.04±.61, women's college: 2.25±.62), with the meaningful difference at the level of t=-2.25, p <.011, and the rest of the factors don't make any meaningful difference. Therefore, the fact that women soccer players get much of serious stress from a sense of shame tells us that we should be more careful about our words and deeds in the field service. In addition, fear of failure accts greatly as the cause of stress, which requires a preventive alternative through psychological training, Finally, it is thought that it is necessary to make athletics performance ability maximalized by making the most of healthy leisure hours.

Since the introduction of phytohemagglutinin (PHA) by Stillmark in 1898, PHA contributed to modicolegal field with new classification of blood types by their agglutination activities to human red blood cells and some of them have been used as lectins instead of antisera. Recently there were reported human serum types classified by their inhibition properties to agglutination reaction of panphytagglutinins with various red blood cells. To classify the serological relationships of human serum types classified by their agglutination activities to cat and rabbit red blood cells, and by their agglutination inhibition properties to D. lablab extract with cat and rabbit red blood cells, agglutination test and agglutination inhibition test with 1409 human sera were carried out. The results could be summarized as follows: 1. Human sera were classfied by their agglutination activities to cat red blood cells, and all rabbit red blood cells were agglutinated by human sera. 2. Human sera were also classified by their agglutination inhibition properties to D. lablab extract with cat and rabbit red blood cells and no serological relationship were demonstrated between them. 3. There were serological relationships between the human serum types classified by their agglutination activities and by their agglutination inhibition properties mentioned. 4. Human sera could be classified into 8 types by combination of their agglutination activities and by their agglutination inhibition properties to D. lablab extract with cat and rabbit red blood cells.
