Objectives: The purpose of this study was to examine whether Temporomandibular Joint Balance Appliance-Golf (TBA-G) can improve postural control ability of healthy adults. Methods: Twenty participants (10 male, 10 female) aged 20 to 39 years were involved. Postural control ability of all participants was assessed before and after applying TBA-G with Balance $Master^{(R)}$ system. Modified clinical test sensory interaction on balance (mCTSIB), unilateral stance, weight bearing and rhythmic weight shift were used to evaluate postural control ability. Results: After applying TBA-G, mCTSIB on a firm plate with eyes open increased from 0.2 to 0.23 (p<0.05) but directional control was improved in slow and moderate velocity of front/back rhythmic weight shift test (P<0.05). In two cases with postural imbalance, most of the postural control measures improved after applying TBA-G. Conclusions: The results suggest that TBA-G could improve balance control ability. A larger controlled trial is needed to determine more accurately the effect of TBA-G on balance control ability.

The purpose of this study was to verify prprioception perception and compare between collegiate golfers and non-golfers using tilting platform. Thirty golfers and twenty-eight non-golfers were participated. All participants were performed perception test on the tilting platform. Frequency analysis was performed using SPSS(ver. 24.0) to determine the perception response according to the grade, and performed using independent t-test. Most participants were perceived from $1^{\circ}$ to $2^{\circ}$ of slopes and perceived left-right slope than forward-backward slope. Repeated practice such as walking on the uneven ground or standing on sloped ground might help to improve proprioception perception. Future research using a tilting platform will be to develop the training program.

The purpose of this study was to investigate the training and detraining effects of a 8-week water exercise on lower extremities coordination during obstacle gait in the female elderly. Eight elderly participants (age: $76.58{\pm}4.97$ yrs, height: $148.88{\pm}7.19$ cm, body mass: $56.62{\pm}6.82$ kg, and leg length: $82.36{\pm}2.98$ cm), who stayed at the Seoul K welfare center, were recruited for this study. All participants had no history of orthopedic abnormality within the past 1 year and completed the aquatic exercise program which lasted for 8 weeks. To identify the training and detraining effect of 8 weeks of water exercise, a 3-D motion analysis with 7 infrared cameras and one force plate sampling frequency set at 100 Hz and 1,000 Hz, respectively, was performed. A two-way ANOVA was performed to find training and detraining effects among diferent obstacle heights. In this study significant level was set at .05. Significant training effects of LTS (lead foot thigh and shank) coordination in all obstacle height were found (p<.05). It is also found that the training effect of LTS remained 37%, 58%, and 25% in obstacle height of 30%, 40%, and 50%, respectively. Lead foot showed the greater detraining effect of coordination compared with trail foot, and SF (shank and foot) coordination revealed better detraining effects of coordination compare with TS (thigh and shank) in both feet. Based on the findings, a 8 week water exercise give an positive effects to the elderly in terms of segment cooperation which potentially helps reducing their accident falls. The magnitude of detraining may also help the elderly to find the retraining moment.

The purpose of this study was to examine clothing purchase behavior of sports participants based on outdoor sports types and sports participation motivation. The research was conducted with the use of a self-administered questionnaire. A total of 703 respondents between the ages of 25 and 55 participated in the research through an internet survey. Motivation for participation in particular sports was comprised of four factors: impress others, mental rejuvenation, social interaction, and health maintenance/improvement. Perceived benefits of clothing choice were categorized into three factors: brand/fashion pursuit, positive image pursuit, and practicality pursuit. Outdoor sports activities was categorized into six types, climbing, jogging, cycling, fishing, golf, and others including ball games. Each sports group presented differences in demographics, sports motivation factors, and benefit factors. Four segments were identified based on sports participation motivation: active group, social group, health and revitalization group, and inactive group. The active group considered three clothing benefits and 14 evaluative criteria as being the most important among the four segments, indicating the major target market for outdoor sportswear brands. On the other hand, the members of inactive group showed passive attitudes toward clothing purchasing behaviors. This study discusses the results of this research within the context of the managerial implication for outdoor sports marketers.

The purpose of this study was to evaluate the difference in grip force and angular kinematic variables between elite (handicap${\leq}2$) and novice golfers. Three-dimensional motion analysis system with synchronized grip force measurement system was used. The participants consisted of two groups based on their playing ability: 10 elite golfers and 10 novice golfers. Each subject performed 5 putting strokes at the distance of 1, 3, and 5m with randomly selected order. During entire putting phase, elite group showed relatively constant grip force but novice group showed continuously increasing grip force pattern. There existed a clear difference in the trajectory of shoulder line between two groups. As for novice group the rotational center did not converge into one point, for elite group the rotational center converged into precise single point. And there was a clear difference pattern in anterior-posterior directional movement at shoulder between two groups. These difference might be helpful for improving consistent putting skills.

The purpose of this study was to compare the differences in kinematic variables and grip forces among professionals(PG), amateurs(AG), and novice group(NG) during golf putting. The participants consisted of 3 groups based on their playing ability: 8 professional golfers (handicap<5), 8 amateurs (handicap<18) and 8 novice. Each subject attempted 2.1m putts from the hole. 3D motion analysis system(Motion analysis Corp., USA) with 6 high speed cameras and grip force measurement system(Kim et al., 2007) were used to acquired kinematic and force data, respectively. To compare differences among groups, joint angles of upper limbs, trajectory and smoothness by jerk cost function(JC) of putter head and grip forces were used in this study. Results showed that there were significant differences among groups in most of variables such as joint angles, trajectory & smoothness of putter head, and distribution of grip force in both hands. In brief, we confirmed that putting stroke in PG was more accurate and smooth than that in other groups, especially NG, due to their well-controlled upper limbs and keeping grip forces constant in both hands. It can be concluded that due to skilled levels, fundamental differences of putting movement could be identified and these differences might be helpful for improving one's putting skills.

This Study is designed to present the concret data on the contents of the economic role and their change in the recent decade among women in a Korean Village. The Case Study method was used and the data was obtained through the participant observation. This Study is composed of the three parts. The first part deals with the effect of the agricultural mechanization upon the agricultural labor pattern of women. The second part examines how the introduction of a golf course and the textile factory in the vinicity affects the labor pattern among village women. The last part tries to demonstrate that the increasing contribution of women to the village economy has not yet produced any positive effect to their social status in the village. This is seen through the detailed description of two important village activities, one social(Tae dong-Gae) and the other ritual (Mokshinjae). The Results of the Study can be summarized as fallows. Firstly, the mechanization of farming is responsible for the increasing marginalization of women's labor in farming. This is particularly true for rice cultivation. Horticulture is still cultivated by women. As the mechanization progresses further, this trend will be more articulated. Secondly, it is found that women are actively utilizing the new external economic opportunities. In fact they are found to prefer those non-farming works to the traditional farming work. The former offers them less burdened work, less working hours, and more income than the letter. Lastly, women are found to be completely excluded from the process of the two important village activities. Only men are participants in them, and women only provides the labor for preparation of food and the necessary chores.
