본 논문에서는 골프 코스 시뮬레이션을 위해 수집된 데이터의 정제 및 처리에 요구되는 딥 러닝 모델과 모델 적용 과정에 대해서 논의한다. 최근 스크린 골프 시장의 확대와 골프 시뮬레이터 기술의 발전으로, 위성 이미지, 항공 촬영 이미지, 공간 정보 시스템 (GIS) 등 다양한 데이터 소스로부터 골프 코스에 대한 정보를 수집에 대한 요구가 증가하였다. 이번 연구에서는 이러한 데이터 소스로부터 생성된 원시 데이터를 최적의 시뮬레이션 입력으로 변환하기 위한 컴퓨터 비전 기법과 딥 러닝 모델 구조에 대해서 검토한다. 특히, 데이터에서 골프 코스 시뮬레이션에 요구되는 메타 데이터를 도출하기 위해 코스 분할(Segmentation)과 코스 오브젝트 분류(Classification) 모델을 적용하는 과정을 다룬다. 이를 통해, 본 연구는 골프 코스 시뮬레이터의 개발 과정에서 중요한 기술 요소를 제공하며, 이는 시뮬레이션의 정확도와 골프 코스의 다양성을 증진시키는데에 기여한다.

본 논문에서는 최신 모션 인식 기술을 활용하여 골프 스윙 비디오에서 사람의 자세를 추정한 후 다양한 원인으로 오검출된 좌표들을 보정하여 자세 추정의 정확도를 높이는 방법을 제안한다. 기존의 사람 자세 추정 모델은 골프 스윙 데이터에서 오검출, 반전, 불안정성, 미검출의 문제를 보여 정확한 자세 추정을 어렵게 했다. 이를 해결하기 위하여 본 연구에서는 자세 추정시 발생하는 이상치 데이터들을 Bi-LSTM 으로 학습하고 골프 스윙의 특징을 고려한 간단한 규칙을 통하여 이상치 데이터를 효과적으로 검출하고 이를 보정하는 방법을 제안한다. 또한 다양한 실험과 분석을 통하여 제안하는 방법이 골프 스윙 모션에서 사람의 자세를 정확히 추정할 수 있음을 보인다.

This study verified the relationships between trust of simulation golf lesson programs, golf passion, and psychological happiness of active seniors. The subjects of study were adults from Seoul, Gyeonggi-do. For data processing, this study conducted frequency, reliability, confirmatory factor, correlation, and structure equation modeling. The results were as follows: First, trust of simulation golf lesson programs had no influence on golf passion (p>.05). Second, trust of simulation golf lesson program had no influence on psychological happiness (p>.05). Third, golf passion (harmonious passion) had a positive influence on psychological happiness (p<.05). However, golf passion (obsessive passion) had no influence on psychological happiness (p>.05).

The purpose of this study is to investigate the effect on the revisit intention and recommendation intention on the golf course selection attribute factors of Chinese golf course users using IPA. In order to carry out this study, a survey was conducted on 388 Chinese golfers, data processing and IPA analysis were conducted, and the following conclusions were obtained. First, the importance of the selection attribute was the highest in employee etiquette, and the price of restaurants and food and beverage was the highest in satisfaction. Second, as a result of the IPA matrix analysis, there were 8 selection attributes for continuous maintenance, 14 for concentration improvement, 5 for low priority, and 3 for excessive effort avoidance. Third, cost, accessibility, course facilities, auxiliary facilities, caddy expertise, and satisfaction with user management were found to affect both revisit and recommendation intentions. Since this study was limited to Chinese golfers, there may be differences in comparing the results with previous studies conducted in other countries on golf culture. Therefore, studies considering cultural diversity should be conducted in the future.

The purpose of this study is to investigate the relationship between golf leader trust, exercise flow and psychological happiness for golf practice users. This study surveyed 256 golfers. The data were used to examine the causal relationship between variables using SPSS 18.0 and AMOS 18.0. Main findings were as follows: First trust of Instructors had a positive effect on exercise flow. Second, exercise flow had a positive effect on psychological happiness. Third, trust of Instructors had a positive effect on psychological happiness. Fourth, exercise flow mediated the relationship between golf participant trust of Instructors and psychological happiness. If golf participants have higher confidence in their leaders and more commitment to exercise, the quality of life will be higher.

This study collected basic data for the design of and research and development for golf wear with an eye toward various consumer needs such as design, activity, function, comfort, and durability as requirements for golf wear. 64 men and women in their 40s, 50s, and 60s were surveyed on the state of wearing golf wear and their satisfaction of the garments. As a result, it was confirmed that the quality of golf wear participants currently possessed did not sufficiently satisfy the research group consumers. Therefore, research and development of golf wear for these consumers should be advanced, while considering reasonable price, age-appropriate design, pattern development, and material selection with keeping in mind the intended activity level as well as comfort. It was thought that the development of functional golf wear would contribute to more comfortable golf activities.

The purpose of this study is to investigate the relationship between trust, satisfaction and cognitive performance of golf participants in golf device, focusing on the swing analyzer. A total of 328 questionnaires were collected. Collected data were analyzed by SPSSWIN and AMOS program and frequency analysis, confirmatory factor analysis, validity test, correlation analysis and structural equation model analysis were performed. The result of the study were as follows. First, the trust of golf participants in golf device data has a positive effect on satisfaction. Second, the trust of golf participants in golf device data does not affect Perceived performance. Third, the satisfaction of golf participants in golf device data does not affect Perceived performance. In conclusion, golf participants' trust and satisfaction of the golf swing analyzer are irrelevant to the perceived performance. In conclusion, it was found that golf participants trusted the data presented through the golf device and obtained satisfactory results. However, in that it did not affect the perceived performance, golf participants can think that golf devices should be used to play golf rather than thinking that golf devices enhance their performance.

This study attempted to verify and examine the effect of screen golf course service quality on reuse. A total of 300 copies were distributed, and a total of 247 copies were used for analysis, excluding 53 questionnaires with poor responses or many missing questions. Based on these results, the following implications were derived. First, screen golf course users were mainly used by friends, acquaintances, and social groups, and information was obtained through human and Internet, and empathy and reliability among service quality affected the reuse of screen golf courses. When users experience high-quality services, they have high satisfaction and high service quality, and they can increase the probability of forming loyalty and recommending and promoting them to people around them. However, experiencing poor quality services can disappoint customers and leave negative comments on people around them, which reduces the likelihood of reuse. Therefore, in order to increase the reuse of golf courses, quality management, customer opinions and feedback must be accepted, and problems must be dealt with quickly to improve the quality of services and provide services that satisfy customers. Second, although the types, responsiveness, and certainty of sub-factors of screen golf course service quality were not significant in this study, management strategies should be used to increase survival in the highly competitive screen golf industry and reuse them by providing differentiated services.
