  • The purpose of this study was to suggest the proper shaft and head fitting methods of the golf club to increase the flight distance of the golf ball. Rotations per minute of the golf ball(RPM), ratio of Ball speed to club head speed(T-Ratio) and launch angle right after impact(LA), which are directly related to ball flight distance, were measured using Spectra with shutter speed of 1/1000sec at the constant head speed of 95mph which was controlled by robot golf swing machine. In order to investigate the effect of club shaft to the 3 selected variables, 10 shafts were used to make ten test clubs with one controlled club head which is the most commonly used by golf players. To measure the effect of the club head to the 3 selected variables, 6 golf club heads which are most commonly used by golfers were selected to make 6 test clubs with a controlled shaft which is one of the best known by players. The shafts and the heads were identified by statistical analysis to increase or decrease the RPM, T-ratio and LA. A proper fitting method of the selected shafts and the club head was suggested to increase the ball flight distance in golf.

  • The purpose of this study is to experimentally analyze swing motion with soft golf clubs and compare with that with normal golf clubs. Soft golf is newly devised recreational sport based on golf but focus on the playability for the elderly. The subject fur the experiment performed swing motion using a normal golf club and a soft golf club in turn. The swing motion of the subjects was tracked using an opto-electric three-dimensional motion analysis system. The results were compared against those obtained with a normal golf club. The range of motion was analyzed along with top head speed for two cases. It was found that higher club head speed could be achieved with reduced range of motion at lumbar joint using soft golf club when compared against the swing using regular club. The lower range of motion fur lumbar bending means reduced risk of injury at the joint. So, it is projected that we can reduce the risk of injury with soft golf while maintaining the club head speed.

  • This study was carried out to investigate the utilizing of cool-season turfgrass in areas, excluding greens, of Korean golf courses. Data collected from 120 golf courses were subjected to frequency and T-test analysis using SPSSWIN. The results obtained were as follows: 1) seventy eight golf curses were utilizing cool-season turfgrass in areas except of the greens. At thirty five golf courses (46.0%) of them, the area utilized appeared tee, green collar, green approach etc. (tee>green collar>green approach). At 37 golf courses(48.7%), a mix of Kentucky Bluegrass and Perennial Ryegrass was utilized and the ratio of the mix was 70:30(v/v). At 57 golf courses(76.0%), seed sowing was utilized. 2) In Korean golf courses, the cognition of utilizing cool-season turfgrass depended on the existence of the practice. The cognition of the experienced was more´ affirmative´ than that of the inexperienced. 3) In the experienced, the preference was determined by turfgrass quality and good appearance and recuperative rate of cool-season turfgrass. In the inexperienced, the preference was determined by turfgrass quality god appearance. 4) The experienced recommended the mix of Kentucky bluegrass and Perennial Ryegrass. 5) It seems that the golf courses having used cool-season turfgrass have difficulties in the maintenance in summer while the golf courses without using cool-season turfgrass have difficulties in the maintenance in summer and the selection of turfgrass variety.

  • Golf has emerged as one of the key leisure activities in Korea. This study examines the characteristics of golf consumption typology. A total of 256 questionnaires were collected from membership and public golf courses in the Incheon and Gyeonggi district. This study explores user satisfaction with and service at the golf course. The results of this research show that there are primary factors in user satisfaction regarding course facility, scores and operational services. Detail responses regarding these golf courses prove that the whole of the golf course, satisfaction with the course layout, landscaping and user gratification with the golf facilities are influenced by contentment with the management of the golf course. Satisfaction with scores were correlated with user contentment with the golf course. Detailed factors regarding operational services cited such aspects as ease of reservations, staff and tee time, all factors related to the smooth arrangements and progress that are influenced by operational services. This research was more concerned with course design and facility operations than marketing operations, which can satisfy users through investment in variety and expansion of the course facilities. Satisfaction in these areas is correlated to revisits and recommendations to others. The types of membership and public golf courses face difficulty in development, operation, and facilities maintenance, among other features. This paper will help separate out each quality in order to formulate difference stratagems for marketing and operation tactics in the future.

  • The purpose of this study is to discovered assessment items for improving athletic efficiency and management of golf courses. Through this, the study intended to provide basic data for creating competitive golf courses and management. Important assessment items were selected by inducing preliminary assessment items and conducting a preliminary survey and a main survey for specialists through a theoretical study. For the survey results studied, reliability and average value for importance were calculated using SPSS/PC Window Release 12.0. As assessment of importance by assessment area, in athletic efficiency assessment, course management level was the highest, followed by fairness of games and operation of games. In management assessment, importance of service level, information management, facility management, management of game assistants, etc. were high. As assessment of importance by assessment item, it was found that 'variety of golf shot' and 'the length of a course' were important in course layout. Also 'start interval among teams' and 'disturbance of play' were assessed as important items in game operation, while 'fair reservation' and 'rounding rotation time' were important in fairness of games. In addition, in information management, 'kind service of golf course staffs' and 'prompt reservation and notification' were found to be important assessment items. In facility management, all assessment indexes were over 4.0, which means all of them are important for quality of golf course and competitiveness. In membership service, 'appropriate price of goods for sale' and 'service for members' were relatively important assessment items. Further, in management of game assistants, 'qualifications and skillfulness of game assistants' was assessed as a very important index. Although the current study only selected important items to assess excellent golf courses, it is necessary to apply the study results to the actual sites and verify them for golf course both at domestic and abroad.
