본 논문은 골프 수행 능력(핸디캡)을 향상시키기 위한 도구인 골프 스코어 관리 시스템을 조사 연구하였다. 이 도구 개발의 주된 목적은 보다 체계적인 골프 스코어의 관리를 돕는데 있다. 이 시스템은 골프 코스 관리, 골퍼 스코어 관리와 코스제자의 세 가지 모듈을 중심으로 구성되어 있다. 골퍼 스스로가 자신의 플레이 정보를 입력하여 과학적인 통계분석을 얻도록 하며, 이 결과를 통해 파악된 자신의 취약점을 개선하도록 하여 골프 수행능력 향상에 커다란 효과를 갖도록 연구하였다.

This study used the questionnaire method to find out the golf factor comparison and purchase inclination according the golfers' demographic characteristics. The golf factor comparison according to the Gyeongnam golfers' demographic characteristics was performed with cross analysis and $X^2$ verification, the purchase inclination with T verification and analysis of variance. And the Golfs' factor relation according to total income was performed with cross analysis and $x^2-test$. The golfers' demographic characteristics showed a significant difference in gender, educational background and occupations. The participation purposes of playing golf for men were as a hobby, relations and business. And the participation purposes of playing golf for women were as a hobby and health. The higher age was, the more the golf career was for both men and women. In the factor of marital status, unmarried people play for a hobby and married people play for better relations and business. In the factor of gross income, male golfers varied in the gold career and monthly playing times. Female golfers varied in the golf career. Regardless of gender, the higher the income was, the more the golf career was. In the comparison of buy behavior according to the golfers' demographic characteristics, male golfers showed a significant difference in ostentation and fashion according to the monthly purchase of golf-wear. The group that spends more on the monthly purchase of golf wear was higher than the group that spends less on the monthly purchase of golf wear. Unmarried golfers showed more ostentation tendency that married golfers.

Robot mobility and intelligence become more important for robots to be used in various fields other than automation. The main purpose of providing mobility to a robot is to extend the robot's manipulability. In this paper, we introduce a small humanoid robot that can autonomously play golf as an example of incorporating robot intelligence, mobility, and manipulability. The robot has 12 degrees of freedom for legs and has various basic walking patterns. It can move to a desired position and change orientation by combining the basic waking patterns. The robot has a color CCD camera and can extract coordinates of the objects in the environments. The small humanoid robot has 8 degrees of freedom for arms and can play golf autonomously with two kinds of dexterous swing motions. Kinematic analysis of the robot arms, vision data processing for the recognition of the environments, algorithm for playing robotic golf have been performed or proposed. The experimental results show that the robot can play golf autonomously.

In this study, we propose a pseudo golf club which can sense user's swing motion and virtual golf simulation system using the pseudo golf club. The proposed system is a virtual golf simulation system of a complex play type in which a player can enjoy various types of golf play according to the user's taste by providing a play mode for hitting an actual golf ball and a play mode for swinging the pseudo golf club. This virtual golf play system calculates and displays the trajectory of a golf ball by a simulator just like playing a real golf, and suggests suitable swing motion, so it helps users to learn golf easily.

We propose a novel simulation method for modeling the game of golf using SystemC, a system description language that allows modeling of a concurrent system's behavior. Utilizing the proposed simulator, we compare different outing formats of golf, namely, regular and shotgun, in terms of playing time. Our simulation results reveal that the shotgun format can take longer than the regular format if the number of groups in a golf course exceeds 33 for the scenario we tested, confirming the belief that the shotgun format can take longer than the regular format. We also justify our simulation by comparing the simulation and analytical results.

The golf industry has become the center of attention for recreational activities in the participant sport market; however, there has been little effort made to understand golf consumer and their consumption behavior using the concept of 'recreational specialization' which segments the golfers based on level of specialization in golf. The purpose of this study was to explore the differences in the relationships among perceived service quality, price of playing golf, overall customer satisfaction with the course, and a player's intention to revisit the same golf course based on the magnitude of recreation specialization in golf. Four public and two private golf courses from the southeastern state of the United States were randomly chosen from a list in a golf magazine. The 365 surveys among 417 participants were ultimately analyzed. Multiple group analysis was conducted in order to investigate differences in relationships among service quality, price, customer satisfaction, and revisit intentions between groups based on the level of recreation specialization. The key findings were 1) for more specialized golfers, satisfaction with price did not affect overall customer satisfaction or revisit intention, however, service quality significantly influenced both overall customer satisfaction and revisit intention, 2) for less specialized golfers, satisfaction with price significantly influenced overall customer satisfaction but did not affect revisit intention. Knowledge about which the determinants of satisfaction are different between more and less specialized golfers could provide a better understanding of how different marketing strategies should be implemented for different specialized levels of golfers.

본 논문에서는 골프채 헤드가 골프공을 일정속도로 움직여 치고 난 후 골프채의 헤드는 같은 방향으로 일정 속도로 움직일 때 골프공을 치고 날아가는 골프공의 속도를 구한다. 골프공을 치기 전의 속도가 각각 다를 경우의 골프공의 속도를 각각 구한다. 골프를 칠 때 헤드의 속도, 골프공의 질량, 임팩트, 임팩트후의 날아가는 속도, 그리고 임팩트 후의 이동 방향 등을 쉽게 알아보도록 하는 것이 본 논문의 목적이다. 실험 결과는 표와 그림으로 자세히 나타나 있고 본 연구와 기존 연구와의 비교 평가 결과와 시사점 및 향후 연구 방향도 제시하였다. 본 연구 결과는 다른 연구와 달리 몇 가지 요소들의 측정으로 우수하게 골프공의 속도를 측정함을 알 수 있다.

Background: Golf is a popular sport involving overhead activity and engagement of the rotator cuff (RC). This study aimed to determine to what level golfers were able to return to golf following RC repair, the barriers to them returning to golf and factors associated with their failure to return to golf. Methods: Patients preoperatively identifying as golfers undergoing RC repair at the study centre from 2012 to 2020 were retrospectively followed up with to assess their golf-playing status, performance and frequency of play and functional and quality of life (QoL) outcomes. Results: Forty-seven golfers (40 men [85.1%] and 7 women [14.9%]) with a mean age of 56.8 years met the inclusion criteria, and 80.1% were followed up with at a mean of 27.1 months postoperatively. Twenty-nine patients (76.3%) had returned to golf with a mean handicap change of +1.0 (P=0.291). Golf frequency decreased from a mean of 1.8 rounds per week preinjury to 1.5 rounds per week postoperatively (P=0.052). The EuroQol 5-dimension 5-level (EQ-5D-5L) index and visual analog scale (EQ-VAS) score were significantly greater in those returning to golf (P=0.024 and P=0.002), although functional outcome measures were not significantly different. The primary barriers to return were ipsilateral shoulder dysfunction (78%) and loss of the habit of play (22%). Conclusions: Golfers were likely (76%) to return to golf following RC repair, including mostly to their premorbid performance level with little residual symptomatology. Return to golf was associated with a greater QoL. Persistent subjective shoulder dysfunction (78%) was the most common barrier to returning to golf.

목적: 골프 운동시 발생한 흉배부 통증의 원인은 늑골골절인 경우가 많다. 이런 늑골 골절은 일반 방사선 검사상 놓치기 쉬운데 이러한 놓치기 쉬운 늑골 골절에 대한 진단에 초음파 검사의 유용성을 확인하는데 있다. 대상 및 방법: 골프 운동 중 발생한 흉부 및 배부통증을 주소로 내원하여 늑골 골절로 진단된 20 대에서 60대까지의 남녀 환자 56명을 대상으로 시행한 일반 흉부 방사선 검사(전후, 측면, 좌우측 사선 촬영)의 결과와 초음파 결과를 비교 통계적 분석을 시행하였다. 결과: 56례의 늑골 골절로 진단된 환자 중 일반 흉부 방사선 검사상 골절로 진단된 경우는 34례였고, 초음파 검사상 골절로 진단된 경우는 51례였다. 흉부 방사선 검사의 민감도는 60.71%, 초음파 검사의 민감도는 91.07% 를 보였으며, 카이제곱 검정상 초음파 검사의 결과가 일반 방사선 검사에 비해 통계적인 유의한 차이가 있었다(P=0.0004). 초음파 검사가 늑골 골절을 진단하는 데 매우 민감한 검사임을 확인할 수 있었다. 결론: 골프운동 중 발생한 흉부 및 배부 통증 환자에 이학적 검사 상 늑골 골절이 의심되는 경우 일반 흉부 방사선 검사상 골절 소견이 관찰되지 않을 시, 초음파 검사가 진단 및 치료에 도움을 줄 수 있다.

이 연구는 점차 증가하고 있는 젊은층과 여성 초보 골퍼들이 골프를 배워가는 과정에서 자세의 어려움, 골프 자체의 지루함, 더딘 실력 향상 등의 이유로 골프에 대한 흥미를 잃고 골프를 포기하는 사례가 많아 이를 보완하기 위한 보조기구를 개발하는 것이 목적이다. 이를 위해 먼저 골프채 그립 하단에 각종 센서를 탑재한 하드웨어 장치를 부착하여 골퍼의 스윙 자세와 비거리 등의 데이터를 수집, 전달할 수 있는 플랫폼을 설계하였다. 이후 이러한 데이터들을 분석, 보관할 수 있는 스마트폰 앱을 개발하고 연동하여 골퍼의 자세를 식별하고 자세를 스스로 교정할 수 있도록 하였다. 아울러 스마트폰 앱은 자기 비교와 타인 비교 콘텐츠를 통해 게임적 요소를 가미하여 초보 골퍼들의 지속적 운동참여를 위한 내적 동기부여도 제공할 수 있다.
