  • This study aims to quantitatively compare and analyze kinetic variables in the motion of male and female professional golfers to suggest basic scientific materials for golf iron swing. Five male and five female professional golfers participated in this experiment. Ground reaction force and foot pressure were measured during performing 10 swings for each participants using an iron club. The result of the ground reaction force indicates that the force occurs at the left foot toward right(-) direction in the mid-downswing(E3) and impact(E4) events in X-axis, while it occurs at the right foot toward anterior(-) direction in Y-axis for both male and female, showing a big difference between them. Also, in Z-axis, large force occurs at the left foot in most events. The analyzed result on foot pressure indicates that men have the highest pressure and area at the left foot, and women have the highest ones at the right foot in the mid-downswing(E3) and impact(E4) events in the max foot pressure, ground contact area and average pressure. It is considered that there is difference of central movement methods between men and women. Thus, different education and training on golf swing should be necessary by gender due to their different patterns of golf iron swing.

  • The purpose of this study was to kinematically analyze the differences between short(2.17 m) and long(10.94 m) putting stroke motions. Thirteen male professional golfers were participated in this study. Experiment was conducted on the artificial grass mat in the gymnasium. Kinematic data were collected by the 60 Hz Kwon3D motion analysis system. Differences were compared by SPSS paired t-test and one-way ANOVA. Duncan was used for post-hoc test and a=.05. The results were as follows: 1. Ground projected trajectory of the putter head were statistically straight during both short and long putts. 2. There was no consistent alignment tendency among shoulder, hip, and stance alignments. However stance alignment was consistent between short and long putts. Thus it is assumed that professional golfers align their body based on their stance alignment. 3. During putting, shoulder rotated not only up and down but also right and left. 4. Left and right elbow distance was maintained during all phases of the putts for both short and long putts. 5. Inter foot distance of long putting was longer than that of short putting.

  • This is a case study on the violent collective activities of spectators in professional soccer games. The purpose of this study is to examine the reasons and the processes of the activities. In order to achieve the purpose well, I analyzed two cases of violent collective activities in spectators of professional soccer games that were held on June 24 and July 28 in 2001. The data for this study was collected from 14 kinds of daily newspapers from June 10 to August 20 in 2001 to maintain the objective validity of the outline, the reasons, and the processes of the violent collective activities of spectators in two cases. The data was collected from Korea Integrated News Database System(KINDS) of Korea Press Foundation, and Chollian, on-line service of DACOM, for its efficiency, accuracy and promptness. On the basis of the above-mentioned method as well as the consequences of data analysis, I've reached to a conclusion as follows. The reasons of the violent collective activities of spectators in professional soccer games were the mass effect, the activities of players, umpires and the results of games, etc. The violent collective activities of spectators in professional soccer games need pre-requirements and have relationships with special affairs that are developed in a regular sequence. In other words, a collective activity gives an effect on another one directly or indirectly. Therefore, this study shows that we can reduce or prevent the damages by the violent collective activities of spectators in sport games when we analyze the processes of collective activities and make a previous counter-measure for that.

  • Due to the competition between the various professional events, it is imperative for the team's management to improve efficiency by removing the inefficiencies of the professional team in order to gain a competitive edge. This study use different Data Envelopment Analysis (DEA) models to measure the efficiency of professional sport organizations. In this mathematical-analytical study, this study first reviews the related literature to analyze the input/output variables. In the end, the variables were detected and the data for this study were gathered from the Korean Basketball League (KBL). While previous studies examine relative efficiency of Korean Professional baseball teams by using CCR model, this study fully utilize the DEA method to investigate Korean professional sports organizations' operating problem. Thus, this study propose full results of DEA analysis such as efficiency score (overall, technical, and scale efficiency), slacks in inputs and outputs of inefficient organizations, Malmquist index) As a result, this study provides not only the exact productivity information of a team and a way of improving a firm's productivity with a decision maker.

Results: As a result of the analysis, it was found that CSR activities had a statistically significant effect on regional attachment. In addition, CSR activities were found to have a statistically significant effect on expansion of fans. Finally, it was found that regional attachment had a statistically significant effect on the expansion of fans. Conclusions: Based on these results, CSR activities of the professional football club are considered an opportunity to build regional attachment. In addition, it is thought that the expansion of fans can be achieved through CSR activities.

  • 본 연구는 프로스포츠팬의 이민자에 대한 인식과 스포츠선수의 국적이동에 대한 인식을 분석하고 이민자에 대한 인식이 스포츠선수의 국적이동에 대한 인식에 미치는 영향을 분석하였다. 이를 위해 프로스포츠 경기장을 직접 찾은 팬 600명을 표집한 후 설문조사를 실시하였으며 다음과 같은 결론을 얻었다. 첫째, 국내로 귀화한 외국인선수에 대해서는 중립적 태도를 나타냈지만 해외로 귀화한 한국선수에 대해서는 개인적 선택을 존중하는 것으로 나타났고 이민자에 대한 인식에서는 중립적인 태도를 보였다. 둘째, 국내로 귀화한 외국인선수에 대한 인식을 종속변수로 한 회귀 분석 결과, 「귀화긍정」에서는 성별요인과 수용적 요인이 종속변수의 39.1%와 38%의 설명력을 나타났다. 「귀화부정」에서는 여성 팬과 이민자에 대한 배타적인식이 높을수록 외국인선수의 국내 귀화를 반대하는 것으로 나타났다. 셋째, 해외로 귀화한 국내선수에 대한 인식을 종속변수로 한 회계분석결과, 나이가 많고 이민자에 대한 배타적 인식이 높을수록 부정적 인식이 높게 나타났으며, 여성 팬일수록 국적이동을 개인의 선택으로 인식하는 것으로 나타났다.

  • The purpose of this study was to analysis of pelvis and lower extremity using orientation angles during a developpe a la seconde. Data were collected by Kwon3D program. Two females professional modem dancer were participated in this experiment. Subjects performed a developpe a la seconde in meddle heights(about 90 dog.) The results were as follows. The orientation angles of pelvis were, in most cases, caused by the movement of trunk and thigh. It was restricted the movement of pelvis within narrow limits because the movement of pelvis was very important to lower extremity alignment. The orientation angle of shank against thigh showed a change of angle about $3-6^{\circ}$ in internal external rotation. The orientation angle of foot against shank showed a change of angle about $6-7^{\circ}$ in internal external rotation.

  • The purpose of this study was to analyze a change of maximal grip forces and EMG of agonists in upper extremity of 8 professional Ssirum players according to Satbar-grip patterns, to elucidate prime agonist muscles, contribution rate of each muscle, and a difference on EMG in upper extremity. one-way ANOVA(RM) performed for average and maximal values of each player after standardization and statistical significance was set as p<.05. The result includes the following: the highest grip force was A type with a statistic significance using one-way ANOVA and Duncan's comparison between A and C type. In summary the highest grip force was exerted on extension in the wrist than flexion in all grip types. Average and maximal values of biceps brachii and brachioradialis muscles were statistically significant and ones of flexor carpi ulnaris and extensor capi ulnaris were not.

  • In order to Know the correct swing methods in golf swing it is important to understand the whole swing path but also the concept of swing plane. But, most amateur golfers don't Know the concept of swing plane well. Therefore this study was trying to make a good material that makes the concept of swing plane easy to understand. A good swing motion data was obtained from a professional golfer using the three-dimensional DLT method. This swing motion was divided into 10 phases and evaluated using the concept of swing plane. The result of the analyze show a good matches between the path of the club and swing plane. This result was summarized as a 3 dimensional graphics to provide a good material to teach the golf swing well.
