The purpose of this study was to analyze park golf-related keywords based on social network data and present park golf trends. Park golf keywords were collected through the crawling process from the Naver News and Blog portals. Python package BeautifulSoup was utilized for crawling, and keyword analysis was conducted using KoNLPy and CountVectorizer for text mining. Furthermore, Document Term Matrix (DTM) was employed to analyze four centralities(connection centrality, betweenness centrality, closeness centrality, and eigenvector centrality). The results were visualized using Network X, yielding the following outcomes.BR Firstly, among the park golf-related keywords, the term ‘golf course’, had the highest frequency, followed by ‘composition’, ‘park, ‘project’, ‘facilities’, ‘hole’, ‘region’, ‘plan’, ‘usage’, and ‘sports’. Secondly, the structure of park golf-related keywords showed that ‘park’, ‘creation’, ‘facilities’, and ‘project’ had relatively high centrality indices.BR As a result, the comprehensive analysis of keywords related to park golf has led to the conclusion that park golf course site selection and development, as well as facility management, have become a prevailing trend. Even the park golf-related business has taken shape as a trend. To promote the activation of park golf, strategic marketing approaches should be implemented, including operational plans through the construction of multifunctional park golf courses, expansion of site areas through private park golf course development, and fostering the park golf industry through the growth of equipment, tour competitions, and coaching.
本研究的目的是基于社交网络数据分析公园高尔夫相关关键词，呈现公园高尔夫趋势。“朴高尔夫”关键词是在Naver新闻和博客门户网站中通过抓取收集的。使用Python包BeautifulSoup进行爬行，使用KoNLPy和CountVectorizer进行关键字分析进行文本挖掘。此外，采用文献术语矩阵(Document Term Matrix, DTM)分析了四种中心性(连接中心性、中间中心性、接近中心性和特征向量中心性)。使用Network X将结果可视化，产生以下结果。首先，在与公园高尔夫相关的关键词中，使用频率最高的是“高尔夫球场”，其次是“构成”、“公园”、“项目”、“设施”、“洞”、“区域”、“规划”、“用途”和“运动”。②公园高尔夫相关关键词结构显示，“公园”、“创造”、“设施”和“项目”具有较高的中心性指数;BR因此，通过对公园高尔夫相关关键词的综合分析，公园高尔夫球场的选址和开发以及设施管理已经成为一种主流趋势。甚至与公园高尔夫相关的业务也形成了一种趋势。为促进公园高尔夫的活跃，应采取战略营销手段，包括通过建设多功能公园高尔夫球场来实施运营计划，通过开发私人公园高尔夫球场来扩大场地面积，通过设备、巡回赛和教练的增长来培育公园高尔夫产业。

This study investigated the relationship between the experiential value and behavioral intention of golf participants through the service landscape of the golf course. A study was conducted on 868 golfers who came to a public golf course located in Yongin, Gyeonggi-do to participate in golf. A questionnaire was used as a research tool, and the data processing method was SPSS 26.0, AMOS 26.0 Ver. Using the program, we conducted regression analysis applying frequency analysis, exploratory factor analysis, confirmatory factor analysis, reliability analysis, descriptive statistics analysis, correlation analysis, multivariate regression analysis, and partial distribution model. As a result, first, the number of visitors to the golf course was Servicescape perception was found to have a partially significant effect on behavioral intention. Second, the servicescape of golf course guests was found to have a significant impact on the experiential value. All sub-factors of servicescape were found to have a significant impact on all sub-factors of experiential value. Third, the experiential value of golf course guests was found to have a significant partial effect on behavioral intention. Fourth, the experiential value was found to partially mediate the influence of the servicescape perceived by golf course guests on behavioral intention. The implication is that the environmental factors felt by golf course visitors should be improved in the mid to long term to improve the course, facilities, environment, service, and value aspects of the golf course and increase the positive image of the golf course. Furthermore, ESG management strategies should be promoted at golf courses to pay attention to the environment by not using chemical products and using grass that grows only from natural groundwater.

The purpose of this study was to investigate the effect of L-carnitine supplement intake before combined aerobic and resistance exercises on body composition, physical fitness, and metabolic risk factors. The subjects of this study were 18 overweight young-adult women with no exercise experience, and they were randomly divided into two groups; combined training+placebo intake group(PLA, n=9), and combined training+L-carnitine intake group(CAR, n=9). Combined training which consists of aerobic and resistance exercises was performed 3 times a week for 8 weeks. To investigate the effect, body composition, grip strength, back strength, power, muscular endurance, cardiopulmonary endurance, blood pressure, fasting blood glucose, blood lipid concentration, and waist-hip ratio were analyzed before and 8 weeks after combined training. Significant differences between group and period were determined with two-way repeated ANOVA. To summarize the results of this study, the oral intake of 2g of L-carnitine supplement with combined training significantly decreased percent body fat and significantly increased fat-free mass, but did not effect on physical fitness and metabolic risk factors. Therefore, our findings suggest scientific evidence that L-carnitine intake and combined training might be used as an ergogenic supplement to improve body composition in overweight young-adult women.

To win in taekwondo need to be able to kick faster and among the factors that influence velocity, core stability is important, but the relationship between core stability and kicking velocity in taekwondo is unclear. The aim of this study was to investigate the association between core stability and lower limb segmental COM velocity at the moment of kick. A total of 13 subjects (male. 172.6±7.3 cm. 64.3±11.78 kg. 2 9±4 years.) participated in this study. Data were captured using 13 infrared cameras at 120Hz, kinematic data were obtained using the motive motion capture system, the data were exported to Visual3D to calculate the centre of mass velocity of the left lower limbs segment at the moment of the kick, the level of core stability was measured using the Sahrmann core stability test and finally the two were analysed using Spearman rank correlation correlation. During the Naraechagi, most of the lower limb segments COM with SCST showed a strong correlation. Therefore, we believe that adding core stability training to taekwondo training has the potential to increase kicking speed. Future research may focus on the effects of stability training.

This study aimed to investigate the mediating effect of physical activity enjoyment on the relationship between enjoyment of virtual classes and class satisfaction during the transition from virtual to face-to-face classes, i.e., whether a blended class, i.e., a combination of face-to-face and virtual classes, is more appropriate than a fully face-to-face class when students have adapted to virtual classes for a long period of time.BR To obtain the above results, this study was conducted from April 24 to May 8, 2023, with a total of 264 students taking a liberal arts physical education class. The results of the study are as follows First, virtual classroom fun positively influenced class satisfaction. Second, virtual classroom fun positively influenced physical activity enjoyment. Third, physical activity enjoyment mediates the relationship between virtual class enjoyment and class satisfaction.BR The implications of this study are that blended learning, a combination of virtual and face-to-face instruction, has a greater impact on class satisfaction than single modalities of either face-to-face or virtual instruction. This study makes a significant contribution to the teaching methodology of liberal arts and physical education, which has been disrupted by the shift to in-person classes this year.

Variables of regional bone mineral density(arm, leg, trunk, ribs, pelvis, lumber, spine, total) were measured and compared between korea dance group and control group as well as pre and post-training using two way repeated ANOVA. Main results were as follows. Both the dance group and the control group had the highest bone density in the lumbar region, and the lowest bone density in the ribs and pelvis regions. Arm, trunk, total BMD was increased significantly in the dance group. lumbar region BMD was decreased statistically significantly in the control group, and the analysis of variance showed a significant difference between groups. Leg region BMD was the analysis of variance also showed a significant difference between groups. Total BMD were statistically significantly improved in the dance group, and as a result of ANOVA, there was a significant difference between groups, and a significant interaction effect appeared. In conclusion, self directed Korean Dance program would have positive effects on regional bone mineral density in female college students with sarcopenia syndrome.

This study used a mixed research method to predict changes in the future Taekwondo industry and Taekwondo Dojang management from the perspective of the Taekwondo business model, and 167 out of 168 Taekwondo masters in the Seoul metropolitan area(Seoul, Gyeonggi, Incheon) were analyzed. As a result, first, it was found that the rent level fluctuates due to population density, inflation, and development of commercial districts between regions. Second, the average training period was 3-4 years, and the main cause was study. Third, as a result of a specialized Taekwondo Dojang survey, there were many subjects such as Poomsae, kindergartens for subjects, direct specialized operations, and jump ropes for graft programs. Fourth, the limitations of Taekwondo Dojang management were external factors, lack of standard educational content, lack of leadership capabilities, Taekwondo Dojang overcrowding, profit structure limitations, and leaders
