        홍영우(Hong Young-Woo),김정묵(Kim Jeoung-Muk) 한국체육과학회 2003 한국체육과학회지 Vol.12 No.2

        The purpose of this study is to investigate the relationship between sports activity and organization commitment. Firstly, the difference of organization commitment of the participation yes or no sports activity, Secondly, the influence of participant degree of sports activity on organization commitment. The subjects of this study was selected by stratified cluster random sampling of involvement(male 367, female 210) in employees'. The survey questionnaires were used to collect the data. The questionnaire for the formalization factor of organization commitment by Choi(1996). The statistical methods such as analysis of covariance, multiple classification analysis were used to analyze the collected data. From the analyses of the data, the study reached the following conclusions: Firstly, organization commitment different sports activity participant character. That is, all of sub-factors of organization commitment is high sports activity participant than non-participant. Secondly, participant degree of the sports activity are influence on organization commitment.

        트레드밀 운동프로그램 적용이 고혈압자의 혈압과 혈청지질 및 심폐기능에 미치는 영향

        홍영우,최건식,정영자,황수관,박철빈 대한스포츠의학회 1996 대한스포츠의학회지 Vol.14 No.1

        In order to clarify how the treadmill program influences the blood pressure, serum lipids, and cardiopulmonary function of the hypertensive adult, total 34 subjects - 26 male subjects and 8 female subjects - in an age group of 30-65 year joined in a program of treadmill exercise which was carried out for 12 weeks sequentially. In the result of such study, findings are as follows; 1. It appeared that systolic pressure and diastolic pressure in a stable condition after the execution of the program significantly decreased(p<0.001) in the male group and the total group, with also decreased heart rate showing as well in these groups. 2. It appeared that forced vital capacity(FVC), forced expiratory volume for 1 second percent(FEVI), and maximum voluntary ventilation (MVV) after the execution of the program significantly increased (p<0.05, p<0.01) in the male group and the total group, and however only maximum voluntary ventilation increased in the female group. Regarding age, FEVI increased more in the age group of less than 50 years than in the age group of more than 50 years. 3. Body weight, present body fat, and fat body weight decreased in all the groups -the male group, female group, and total group since the execution of exercise, and body fluids increased only in the male group, and total group. Regarding age, persent body fat decreased more in the male group whose age is less than 50 years and in the female group whose age is more than 50 years than in other groups. Regarding the decrease rate of blood pressure, the group in that systolic blood pressure decreased more than 20mmHg in male body fat rate and the group in that diastolic blood pressure decreased more than 11mmHg showed more decrease rate blood pressure than other groups. 4. Total cholesterol(TCH), low density lipids protein(LDL), ratio of total cholesterol to high density lipids protein and triglycerides(TG) decreased in all the groups - the male group, female group and total group since the execution of exercise, however high density lipids protein increasing. Regarding age, total cholesterol decreased more in both the male female groups whose age is under 50 years than both the male and female group whose age is above 50 years. And triglycerides decreased more in the female group whose age is under 50 than in the female group whose age is above 50. Regarding the decrease rate of blood pressure, the group in that systolic blood pressure decreased more than 20mmHg in male triglycerides and the group in that diastolic blood pressure decreased within 6-11mmHg showed more decrease rate of blood pressure than other groups. 5. Heart rate in exercise decreased after the execution of the program than before the execution of the program. 6. The increase of systolic blood pressure in exercise decreased in all the groups- the male group, female group, and total group, however no change showing in their diastolic blood pressure. 7. The amount of oxygen uptake in exercise and after exercise inceased in all the groups - the male group, female group, and total group after the execution of the program than before the execution of the program. 8. Maximum oxygen uptake significantly increased(p<0.01) in all groups - the male group, female group, and total group after the execution of the program. 9. A regression equation showing the relations between systolic blood pressure, heart rate and oxygen uptake was obtained, and it indicated a close relation between them. Based on the finding indicated so far, those results after the application of the treadmill exercise program to hypertensive adults such as decrease in blood pressure, weight, body fat rate, and body fat, increase of body fluids, improvement of the metabolism of serum lipids and cardiopulmonary function, and more increase of both systolic blood pressure and diastolic blood pressure in the male group whose age is less than 50 years than in the male group whose age is more than 50 years-all these indicates significance. And also, based on the regression equation, the possibility to estimate heart rate and oxygen uptake with only systolic blood pressure is a noteworthy result of this study.

      • 卓球選手의 競技內容에 關한 分析硏究

        申甲浩,洪榮佑 明知大學校 自然科學硏究所 1984 자연과학논문집 Vol.2 No.-

        In this study I could get a few results as follows from making out the couses of gains and loses of games acconding to batting tachnique selected from several semifinal games of players porticipotel in the Second Seoul International table tennis game, and from comporing and analyzing also the ralation to gaining and losing -points depending in the effctiv e methods and any other technique in controlling the game management. 1. We can easily find and so I could attain the average contents, s follows, of each player's game of gaining and losing points and ball dropping paints according to the technique of batting balls. A)Mr. Park's stroks number amaunted to 34.91 in all of his games, the forehand's 23.95 strokes were more often than backhand by 13 strokes, and forehand strokes gained 12.98, lose 10.97 and backhand strokes gained 4.32, and losed 6.04 The most major couse of gaining points was "cutting" balls(6.66)and that of losing points was "Smashing'(4.16). B)Eric Boggan stroked the balls 41.5 times in tatal which contain 16.5 strokes of backhand and 25 strokes forehand, and he losed 16.50 points in back strokes and gained 15 points, and his forehand smashing strokes made him enable to gain most of points of them by 4 times,.on the other hand, losed by short of back strokes of 4 times. C)Mr. Waldner stroke balls 41.5 time in all forehand strokes 28.5 time was more than backhand strokes and his main coerse of gaining points was 15.5 time of forestrok and was more than 6.5 times of backstrokes and alsed points by forestrokes in 13 times, while backstrokes make him lose points in 6.5 times and he could have same points gained and losed in using the backhand strokes, while forehand strokes gained more points 15.5 to 13 points We could find him get more points by the same forhand Driving. D)The total stroke number of Maehara Amounted to 34.58 times. Forehandstrokes were 29.28 times . and backhandstrokes only 5.3 time And he losed more points in forehandstrokes (gained 13.97 points losed 15.31 points)And the fact, that he mainly gained by using the backhandstrokes by gaing 3.31 points to 1.99 losing points, may be colled peticular phenomenon. His 'Forehand spin euabled him get more points by getting 7.66 times and he losed points 8.66 times by using Forehand spin method. E)Miss Shin strokes balls 41 times in all and she mostly used Forehandstroke 33 times and there were no deffernces in gaining and losing points in 16.5 time whether she used Fore or Backhandstrokes, But she mainly get points by Forehadn Smashing of 7 times and losed points by Forehand spining. F)Mis Lee's stroke number were Cmporably loss than other players and amounted to 32.28 time in all her Forehandstroke came up to 28.63 times, but losed more points by it than gainded by 11.32 to 17.3 points and also in Backgandstroke gained 0.99 time and losed 3.66 time, Her main skill was Forehand spin dn it mde her more points in 8 times, and lose times by skill. G) Wada's tatal strokes amounted to 36.2 time and Backhand strokes number were of 22.6 time which shows more strokes than 13.6 time of Forehandstrokes, and it can be side the only phenomenon of Miss Wada, she could get paints more often by Backhandstroke than by Forehandstroke(Forehand 9 to Backhand 12)she also losed more points by Backhand( fore 4.60 to Back 10.6). Her favorite skills, back long-cut (5times)and Both -cut (5 times) enabled him equally gain most o points and mostly she losed points by Bachand long-cut,(5.8).
