The effect of low-dye taping technique applied to flexible flat-footed adolescents on mSEBT and Standing long jump in place was investigated. The subjects of this study were 35 youths with flexible flat feet, 17 people with elastic tape and 17 people with non-elastic tape, and the low-dye taping technique was applied. The data analysis of this study used t-test to compare before and after the application of group intervention, and between each group. As a result of the study, significant results were found before and after the application of the intervention in mSEBT and Standing long jump in place (p<.05), and there was no significant difference in comparison between groups (p>.05). In conclusion, the low-dye taping technique applied to adolescents with flexible flat feet is effective for mSEBT and Standing long jump in place, and low-dye taping is appropriate as an intervention method to see the immediate effect of raising the inner longitudinal bow.

The purpose of this study was to investigate the effects of 12 weeks of muscle power and agility training on physical fitness factors and isokinetic muscle function in elementary school male soccer players. For this purpose, 6 muscle power and agility training programs were organized for 12 elementary school male soccer players and were conducted 3 times a week for 12 weeks. The results of measurement and analysis of physical fitness factors before and after the muscle strength and agility training are as follows. First, there was a significant difference in the standing long jump in place of muscle power(p<.001). Second, there was a significant difference in the standing vertical jump of muscle power(p<.05). Third, there was a significant difference in the side step of agility(p<.01). As a result, 12 weeks of muscle power and agility training can be expected to have a positive effect on the improvement of agility and agility of elementary school male soccer players, and it is judged that it can provide training basic data for injury prevention and performance improvement.

The purpose of this study is to analyze the effect of one-off capraise movement on the quickness of the lower extremities among the basic physical strength factors. The subjects of this study were 16 students majoring in physical education at Y University in D Metropolitan City, and all subjects were familiar with the contents of the measurement items and crime prevention, and the experiment was conducted with the students who answered the questionnaire and agreed. In summary, it seems that only a single calfraise is effective in strengthening the quickness of the lower extremities, and in particular, it is judged that the thicker the circumference of the calf muscle, the more it affects the quickness of the lower extremities. In addition, although the results of this study may not be considered to be effective for all ages, it is considered that it is good to use it as basic data for physical fitness evaluation as it shows the effect of improving records only with a single exercise. In future studies, it would be nice to recruit subjects by age and conduct studies that can raise the need for exercise through age differences.

Before (March 26, 1994) or after the occurrence of a downslope windstorm (March 29), the NO, $NO_2$, and $SO_2$ at the ground level of Kangnung city were monitored with high concentrations in the afternoon, due to a large amount of gases emitted from combustion of motor vehicle and heating apparatus, especially near 1600-1800 LST and 2000-2100 LST, but at night, they had low concentrations, resulting from small consumptions of vehicle and heating fuels. When both moderate westerly synoptic-scale winds flow over Mt. Taegwallyang and easterly meso-scale sea breeze during the day, atmospheric pollutants should be trapped by two different wind systems, resulting in higher concentration at Kangnung city in the afternoon. At night, the association of westerly synoptic wind and land breeze can produce relatively strong winds and the dissipation by the winds cause these low concentrations to lower and lower, as nightime goes on. From March 27 through 28, an enforced localized windstorm could be produced along the lee side of the mountain near Kangnung, generating westerly internal gravity waves with hydraulic jump motions. Sea breeze toward inland appartantly confines to the bottom of the eastern side of the mountain, due to the interruption of eastward violent internal gravity waves. As the windstorm moves down toward the ground, an encountering point of two opposite winds approaches Kangnung, and a great amount of NO and $NO_2$ were removed by the strong surface winds. Thus, their maximum concentrations are found to be near 18 and 20 LST, 17 and 21 LST. In the nighttime, the more developed storm should produce very strong surface winds and the NO and $NO_2$ could be easily dissipated into other place. The $SO_2$ concentration had no maximum value, that is, almost constant one all day long, due to its removal by the strong surface winds. Especially, the CO concentrations were slightly lower during the strom period than both before or after the strom, but they were nearly constant without much changes during the during the daytime and nighttime.
