The plant parasitic nematodes were surveyed from Zoysia matrella, Agrotis palustris, and Poa pratensis at Anyang Benest Golf Club, Dongrae Benest Golf Club, and Gapyeong Benest Golf Club and from A. palustris at Castle Pine Golf Club. Criconema sp., Ditylenchus sp., Helicotylenchus sp., Meloidogyine sp., Pratylenchus sp., Tylenchus sp., and Tylenchorhynechus sp. were separated from unhealthy turf areas. In addition, Tylenchorhynechus dubius was firstly recorded from A. palustris at the green of Castle Pine Golf Club. Meloidogyne sp., Helicotylenchus sp., Ditylenchus sp., and Pratylenohus were separated from Z. matrella, Meloidogyne sp. and Pratylenchus were from A. palustris, and Meloidogyne sp., Tylenchus sp., Tylenchorhynchus sp., Criconema sp., and Helicotylenchus sp. were from P. pratensis. Out of separated nematodes, Meloidogyne was the most serious nematode and widely distributed.

The purpose of this study is to present a caddie education program that can improve the performance of golf caddies in China by comparing and analyzing the golf caddie education programs in South Korea and China. Caddie education programs were collected from 4 golf clubs, 3 professional caddie education institutions and 8 public institutions in South Korea and 6 golf clubs and 2 professional caddie education institutions in China. The following results were obtained. Although the caddie training in China is conducted over more time and term than in South Korea, it is necessary to have an education program considering golf expertise and quality of customer service. Therefore, the caddie education program in China is composed of golf related education(golf etiquette, golf practice skill), caddie duty training(safety management, customer service and image making), and training for caddie(fitness management, injury prevention, skin care, and cost-saving etc.). In the future, the Chinese golf club industry will has a potential to develop. In order to provide a consistent and systematic education, manual training on caddie education and training on caddie master to manage caddies should be conducted.

The impact sound of the golf club is one of the major factors to purchase it. Sound quality metrics has been mostly developed for harmonic sounds. Sound quality evaluation techniques for the impact sound have been contrived in this study. Jury test, one of the typical subjective evaluation scheme, is carried out for evaluating the sound quality of 13 different golf drivers, which classification results are assumed to be correct answers. Conventional objective evaluation methods such as Zwicker loudness sensory pleasantness are calculated. Wavelet analysis and instantaneous loudness are applied in order to evaluate the sound quality of transient sounds, which scheme shows better correlation with the results from jury test.

Host plants of Popillia flavosellata (Coleoptera: Ruteridae) were investigated at the courses of three golf clubs, East Valley Golf Club, Anyang Benest Golf Club, and Anseong Benest Golf Club and their surrounded forests. In addition, seasonal occurrence was examined from East Valley Golf Club using Japanese beetle pheromone lure and a eugenol feeding attractant. Twenty six species of 25 genera in 18 families were recorded as hosts of P. flavosellata from given surveyed golf clubs. Out of them, 22 species of 21 genera in 15 families were newly recorded host plants of P. flavosellata. Thus, host plants of P. flavosellata were 49 species of 41 genera in 23 families in total including hosts from literatures. The main damage part of P. flavosellata adult was flower of host plants. Peak activity of P. flavosellata adult was observed around 20 June. Mean numbers of attracted P. flavosellata adults at the peak day were 197.6/trap/day in 2008 and 268.1 in 2010, respectively. Occurrence of P quadriguttata was much lower compared with P. flavosellata at the given golf club. That is, mean numbers of attracted P quadriguttata adults from the same trap at the peak: day were 0.4/trap/day in 2008 and 2010, respectively.

Computer-Aided Engineering (CAE) is one of the most effective method in design of golf clubs for determination of optimum shapes in short lead time. A new design of golf club drive with gas-filled titanium head has been carried out using two FEM softwares MARC and DYNA-3D. The main research work focuses on the decision of face thickness and the effect of filled gas pressure by analyzing the change of the kinematic energy of the ball during impact.

Objective: The aim of this study was to identify the biomechanical determination factor for improving club head speed during the driver swing in male golf players. Method: Twenty-seven golf players were participated in this study. Eight motion capture cameras (250 Hz) and two force plates (2,000 Hz) were used to collect peak angular velocity and ground reaction force data. It was performed stepwise multiple linear regression analysis and alpha set at .05. Results: The peak plantar flexion angular velocity of the left ankle joint and the peak adduction angular velocity of the right shoulder joint were statistically significant. The peak plantar flexion angular velocity of the left ankle joint and the peak adduction angular velocity of the right shoulder during downswing. Conclusion: It is suggested that applying body conditioning training aimed at improving related body functions to increase maximum plantar flexion angular velocity in the left ankle joint will be effective in improving club head speed.

This study analyzed performance according to kick point and stiffness of Soft-$golf^{TM}$ shaft. This research team developed soft-$golf^{TM}$ as a new fusion sports with similar motions with golf and it can be learned safely for all age groups in 2002. The head of Soft-$golf^{TM}$ club is made of zinc alloy and has a mesh or a grid structure, and shaft uses carbon graphite to reduce the total weight of the club. To improve carry distance and to assure consistency of a ball during Soft-$golf^{TM}$ swing, this study manufactured shaft with various kick points (low, middle and high) and stiffness (stiff, regular, lady, morelady) and analyzed a swing motion with characteristics of each shaft presented in a dynamic condition such as a ball's speed, a head's torsion angle and a ball's deviation with ProAnalyst program through a high-speed camera taking pictures using a swing machine robot system(Robo-7). From all of the results, this study determined an appropriate shaft of Soft-$golf^{TM}$.

This paper presents a visual tracking algorithm for the golf swing motion analysis by using the information of the pixels of video frames and movement of the golf club to solve the problem fixed center point in model based tracking method. The model based tracking method use the polynomial function for trajectory displaying of upswing and downswing. Therefore it is under the hypothesis of the no movement of the center of gravity so this method is not for the amateurs. we proposed method using the information of pixel and movement, we first detected the motion by using the information of pixel in the frames in golf swing motion. Then we extracted the club head and hand by a properties of club shaft that consist of the parallel line and the moved location of club in up-swing and down-swing. In addition, we can extract the center point of user by tracking center point of the line between center of head and both foots. And we made an experiment with data that movement of center point is big. Finally, we can track the real trajectory of club head, hand and center point by using proposed tracking algorithm.

Competition to attract customers to the increase of the golf club, but the less people enjoying golf for a variety of issues, including the economic downturn, so golf is going deepened. Therefore, the local golf club is faced with the difficulty of management. In the case of the golf club human resource is the most important factor, because it has a high labor intensive nature of the industry as a type of facilities and services on the basis of intangible human resources. In this paper, to confirm the internal marketing activities and internal service quality, basic premise is that for an external customer satisfaction, internal customer satisfaction should be preceded, and try to analyze these execution factors on job satisfaction and customer orientation, either directly or indirectly affected. The empirical results, the management support in the internal marketing activities were the factors affecting the intrinsic job satisfaction, and the internal service quality were factors affecting employees of the intrinsic job satisfaction and extrinsic job satisfaction.
