An application implementation that allows users to train yoga posture based on the landmark of yoga posture of yoga instructors obtained from the Google Firebase ML Kit was introduced. Using the ML Kit, the user's posture is classified and landmarks corresponding to each joint are obtained. The accuracy measurement reference value for the yoga posture is set through the angle formed by the joints of the obtained landmark. The accuracy between the reference landmark for the yoga posture of professional yoga instructors and the landmark for the user's pose through the ML Kit was compared. According to the accuracy reference value, information on malfunction and correct motion is provided to the user through Text-to-Speech (TTS). Users are managed effectively with Firebase, and a system that displays the amount of exercise through a counter and timer when the user performs an exercise that meets the accuracy reference value was explained.

This study aims to analyze the relationship among emotional labor, Job burnout, and organizational citizenship behavior(OCB) of yoga instructors. Especially, we focused on the mediating effect of job burnout between emotional labor and OCB. A total of 250 questionnaires were distributed and 221 were returned for final analysis. In order to verify the hypothesis, structural equation modeling was conducted using AMOS 23.0. The results of this study were as follows: First, surface acting had a positive effect on job burnout, but deep acting had no significant effect on job burnout. Second, job burnout had a negative effect on OCB. Third, Surface acting had no effect on OCB, but deep acting had a positive effect on OCB. Last, the relationship between surface acting and OCB was perfectly mediated by job burnout, however there was no mediating effect of job burnout between deep acting and OCB.

South Korea is entering an aging society, and since the musculoskeletal system directly affects elders' daily life, muscle exercise and flexibility are required. In particular, yoga relaxes the mind and the body and heightens stress coping ability. To investigate keywords about yoga, news articles provided by BIGKinds, a news analysis system, was applied to collect articles from January 1, 2019, to December 31, 2021, and an analysis was conducted about the monthly keywords and the relationship followed by the weighted degree. Based on the research findings, first, it showed that there is high interest in yoga during the spring and autumn seasons. Second, yoga is offered in non-contact methods nowadays, and various social network services are applied for the operation. Third, there was high public attention to articles on yoga instructors and trainers, and this revealed the importance and interest in online coaching. It is anticipated to apply it for the development of yoga workout programs and base data to develop sports for all.

The purpose of this study was to investigate range of motion (ROM) and muscle activities according to the skills of Surya Namaskara in Vinyasa Yoga. Six females (skilled 2, unskilled 4) of university students participated in this experiment. The research factors were ROM and muscle activities for static poses on Surya Namaskara in Vinyasa Yoga. The six infrared cameras (Oqus 300, Qualisys Inc, Sweden) and Zero Wire EMG (Aurion, Italy) were used to acquire raw data, and the Qualisys Track Manager and Noraxon (MyoResearch XP Master Edition, USA) were used to process data. The %MVIC and ROM were analyzed with Visual 3D (C-Motion Inc, USA) and Noraxon. In conclusion, ROM and %MVIC between two groups were remarkable different according to the static poses of Yoga, therefore instructors have to provide step-by-step information that was suitable to themselves (ROM and EMG of poses).

The purpose of this study was to examine the current status of elderly sports both domestically and internationally, and to explore strategies for the activation of Silver Taekwondo as one of the sports disciplines for the elderly. To investigate the status of elderly sports globally, press releases and statistical data from various national public institutions and sports facilities (including the Ministry of Culture, Sports and Tourism, the Ministry of Health and Welfare, the Korean Statistical Information Service, e-National Indicators, and the Korea Sports Promotion Foundation) were collected. Comparative analysis with related papers, journals, and books led to the following findings for activating Silver Taekwondo. Firstly, elderly sports in South Korea are primarily conducted through welfare centers, with a preference for dance, yoga, and music, while martial arts, including Taekwondo, had a lower preference rate. To increase participation in Silver Taekwondo, a variety of marketing approaches, similar to those used internationally, such as experiential case studies in media, film production, distribution, and telephone promotions, are necessary. Secondly, the development of Silver Taekwondo programs tailored to the training targets and the cultivation of instructors capable of executing these programs are needed. The development of programs should involve collaboration with Taekwondo institutions, dojangs, universities, and lifelong education centers, requiring the participation of majoring students and elderly sports instructors.
