The purposes of this study were to examine whether aquatic exercise has influence on the neuroplasticity and vestibulo-motor function in diffuse brain injury rats. 80 Sprague-Dawley rats were assigned to four groups; Group I: control group (n=20), Group II: aquatic exercise (n=20), Group III: treadmill exercise with change of velocity and inclination (n=20), Group IV: simple treadmill exercise (n=20). And we applied exercise each groups for 3 weeks except Group I. Before the rats were sacrificed to identify immunohistochemistry study at each time of measurement day, Rota-Rod test was given to assess changes in vestibulomotor function. then, the immunohistochemistry study of GAP-43 in discrete regions of the rat brain was performed to measure changes in neuroplasticity. The results demonstrate that aquatic exercise group is more effective than other groups. expression of GAP-43 and vestibulo-motor function were increased most in aquatic exercise group. Therefore, this study suggest that aquatic exercise may effective therapeutic approach to increase neuroplasticity and vestibulo-motor function in traumatic brain injury.

The purpose of this study is to analyze the difference of the effect of adult golf participation on the exercise adherence through the exercise immersion and to suggest the adherence golf exercise. To achieve this purpose, 40~70 age subjects of adult golf club located in Gyeongsangnam-do jinju city were selected in January 2020 and sampled by systematic cluster random sampling. First, factor analysis and reliability analysis were conducted to secure validity and reliability. Second, the frequency analysis average(M) standard deviation(sd) were conducted to investigate the general characteristics of the respondents. Third, t-test and one-way ANOVA analysis were conducted to identify differences between exercise immersion and exercise adherence according to general characteristics. Fourth, correlation analysis and multiple regression analysis were conducted among variables. The results of this study through these methods and procedures are as follows. First, there was no significant difference in the exercise impression and exercise adherence of general characteristics. Second, exercise immersion showed a high difference in exercise adherence. Third, exercise immersion had a high effect on exercise adherence.

A series of experiments has been performed to investigate the flapping motion, which has been generally considered as an intrinsic characteristic of plane flow, of the horizontal merging buoyant jet discharged into stationary ambient water. For Horizontal merging buoyant jets, the flapping motions has been observed and the average onsets of flapping motion coincided with the start of merging transition. The Strouhal number, which describes the measure of frequency of vortices on the flow boundary with respect to the local properties of the flow, varies and converges to a constant value over merging transition. Considering the merging transition and the variation of local flow properties, the characteristics of flapping motion of plane flow can be applied to merging buoyant jets.

Objectives: This study was conducted to investigate the change of health status through the intervention of physical activity arid exercise program for the people living in the area where health promotion program has been executed. Methods: The data was obtained from self--administered questionnaire. The questionnaire consisted of general characteristics, physical activity transition and health status variables using the SF-36(36-Item Short-From Health Survey). Data were analyzed 134 subjects participating in the physical activity arid exercise intervention programs. Results: The 35.1% of adults above 20 years of age are regularly physical activity and exercise before intervention program. but the rate increased to 49.3% after that. Frequency and duration of physical activity were increased, and frequency of participating in physical activity was increased from 0.9 times a week to 2.1 times especially. Scores of health status measured by SF-36 was increased in category (if general health after intervention of program, but those were decreased in category of vitality and mental health. Physical function of four groups classified by change of behavioral pattern were increased after intervention of program, especially in groups starting to physical activity. Conclusions: Physical activity and exercise is associated with health status. This study suggest that effective strategy and policy supporting for the promotion of physical activity and exercise should be needed in all peoples.

Park golf is establishing itself as a daily sport that the silver generation can enjoy physically and cost-free. Accordingly, we have examined the impact of park golf participants' passionate participation behavior on sports immersion and sports performance. The subjects were 243 park golf participants, and SPSS 21.0 and AMOS 18.0 were used for data processing. In addition, frequency analysis, reliability, confirmatory factor analysis, and correlation analysis were conducted. Path analysis was performed using SEM, and mediating effects were analyzed using bootstrapping. First, regarding the relationship between passionate behavior and sports immersion, harmonious passion did not affect sports immersion, and obsessive passion had a positive effect. Second, passion had a positive effect on sports performance. Third, sports immersion had a positive effect on sports performance. Fourth, sports commitment played a partial mediating role in the relationship between passion and sports performance. Therefore, if the environment of the park golf course is improved so that passion does not decrease, exercise immersion and exercise performance will improve.

The purpose of this study is to investigate the effect of the perfectionism tendency of university athletes on athletic commitment, and ultimately to provide the importance of psychological factors to foster excellent athletes. A survey was conducted on 170 athletes attending universities in Hanam, China and Suwon, Korea. To achieve the purpose of this study, it was analyzed using SPSS 22.0. As for the analysis method, frequency analysis, exploratory factor analysis, internal uniformity, Pearson correlation analysis, and multiple regression analysis were performed. As a result, in the effect of the perfectionist tendency of Chinese university athletes on exercise commitment, behavioral commitment and cognitive commitment among the perfectionist tendencies of university athletes had a significant effect. Through this study, it is believed that it will be meaningful for university athletes to provide basic data by investigating the relationship between perfectionism tendency and exercise commitment of university athletes.

Recurrent motor branch entrapment syndrome is a compressive mononeuropathy of recurrent motor branch of median nerve. It is a rare condition as a cause of thenar muscle wasting and may have different pathogenesis. If such an anatomical variation is the cause, there is a possibility that thenar muscle atrophy remains if only the transcarpal ligament release is performed. We report a 25-year-old male patient with carpal tunnel syndrome with thenar muscle wasting 1 month ago.

The author studied EEG differences among normal, children, children with emotional behavioral problems determined by Rutter's questionnaire and children with attention-deficit hyperactivity disorder according to DSM-III-R. The results are as follows ; There were no differences in incidence and pattern of abnormal EEG between normal control children and children with emotional behavioral problems. But children with attention-deficit hyperactivity disorder tend to show lower average amplitude, and less wave percentage time of alpha wave in occipital area than normal did, furdermore wave percentage time of alpha wave appeared more in left occipital area than in right occipital area, These results demonstrated that emotional behavioral problems in elementary school children may not be related to EEG abnormality, Where as children with attention deficit hyperactivity disorder showed underdeveloped alpha waves as compared with normal control children.
