Abstract
The purpose of this study was to identify the possibility of applying intensive combined training by analyzing the effects of intensive combined training of visual dependence and proprioceptive dependence on perceptual judgment and performance in golf putting. Forty-eight male novice golfers participated in the experiment. They were randomly assigned to one of four groups; visual-dependent, proprioceptive-dependent, intensive combined, and control groups. The experiment was conducted in the order of pre-test, training session, and post-test. In the pre-test, 15 golf putting was performed once per each distance from 1 to 15m. During the training period consisting of 3 blocks, subjects conducted golf putting 30 trials, 2 times for each distance from 1 to 15m in each block. The post-test was performed after the training session in the same manner as the pre-test. At each test session, absolute (AE) and variable error (VE) representing the accuracy and consistency of perceptual distance and performance in golf putting were measured. In the blocked session and post-test, AE and VE for perceptual judgment distance and performance were significantly reduced in the combined training group compared to other groups. These results suggest that the intensive combined training of visual dependence and proprioceptive dependence can be a more effective training method in a closed motor skill like golf.

Abstract
The purpose of current study is to classify the types of YouTube sports content using a two-step cluster analysis, and to analyze the characteristics of each classified type of YouTube sports contents. Through this, we tried to provide necessary information for market strategy by understanding the characteristics of sports content products in a new media environment especially on YouTube platform. To achieve this purpose, 124 major sports-related channels active on the YouTube platform were selected. 89,912 contents posted on the selected channel and web data formed on the contents were collected as analysis data using web crawling technology, data mining API, and contents analysis. The collected data were classified into five types of clusters by a two-step cluster analysis using three standard variables(sport type, content function, and thumbnail format), and the clusters classified afterwards were ‘video Mechanical Format’, ‘Performance Indicator’, ‘Easy to access video’, and ‘Creator property’ were used to analyze the characteristics of the contents. As a result of the analysis, the content cluster was classified into 5 clusters(area competitive sports-entertainment type contents, field competitive sports-social type contents, area competitive sports-analysis type contents, recorded competitive sports-analysis type contents, combat and training sports- lesson conets). And it was found that the clusters showed differences according to each content characteristic variable. Based on these results, the types of sports contents posted on YouTube were classified, the main characteristics of each type of contents were identified, and theoretical and practical implications for the new sports media market were discussed.

Abstract
Aging induces physiological changes in the human body. One of the major changes due to aging includes the decrease in muscle mass and strength, which is called sarcopenia. Sarcopenia is caused by various factors, among which the reduction of satellite cells is one of them. Satellite cells are a type of stem cell that regulates the process of muscle fiber regeneration and growth processes. It has been reported that exercise increases the content and function of satellite cells despite the fact that aging causes them to decrease. Exercise can also be used as a major strategy for improvement of aging satellite cells, as positive responses are shown in aged satellite cells regardless of exercise modes. Therefore, this study was conducted to provide additional information that can improve the health concerns of the elderly by reviewing previous studies on the characteristics and functions of satellite cells and suggesting the response of them to exercise of different modes.

Abstract
eSports is generally called as game. Here, game is used as a word with negative connotations compared to sports. However, if games mean competition and institutionalization, the orientation of sports-related games and eSports-related games is not different each other. This study attempts to explain that game is a word that can be applied to sports or eSports at the same time. The results of the study are as follows. First, Caillois describes the characteristics of four games: agon(competition), alea(chance), mimicry(simulation), ilinx(vertigo). These characteristics of game are also found in eSports. However, due to digital attributes, the emphasis on game-related eSports is only different. Second, according to Caillois, the characteristics of this game show the properties of sociality and corruption in the relationship between human nature and the sociocultural environment. In other words, we show the positive aspect when the game effectively retains human nature, while we see the property of degradation when it fails to control human nature with will. The same is true of eSports. Third, Caillois explains by imitation as one of the characteristics of the game. In other words, imitation is human nature and the driving force behind the game. Imitation evolves into simulation in eSports and into VR/MR/AR eSports.

Abstract
This study aimed to examine baby boomer’s correlation between physical activity, sedentary time, and subjective health by considering the differences of individual prevention of infectious diseases in the COVID-19 Pandemic. An online survey was conducted and we analyzed 282 baby boomers. The analysis of frequency, exploratory factor, Pearson’s correlation, multiple regression, and independent t-test were performed and the results are as follows. 1) Leisure-time physical activity showed a significant positive relationship with the subjective health. All types of physical activity and sedentary time showed a significant negative correlation. 2) Walking activity showed a significant positive relationship with the social distancing practice. 3) The degree of leisure-time physical activity was significantly lower and the sedentary time was significantly longer in the COVID-19 high-risk group. Among the types of physical activity, leisure-time physical activity could increase the level of baby boomer’s health in the COVID-19 Pandemic, and reducing the sedentary time can diminish the infection rate. Additional research is needed on the result that people who practice social distancing do more walking activities.

Abstract
This study verified the development and feasibility of relative leisure deprivation scales for standardized and validated scale development to objectively measure subjective emotional states that individuals feel relatively unequal to overall leisure resources. The survey was conducted through mobile in October 2020 and the final 512 copies were used for the final analysis. The SPSS 25.0 and AMOS 25.0 statistical programs were utilized to conduct frequency analysis, descriptive statistical analysis, exploratory factor analysis (EFA), question analysis, reliability analysis, and confirmative factor analysis (CFA), and correlation analysis. The conclusions drawn are as follows: First, the factors of relative leisure deprivation were derived from the individual’s egoistic, resourceful, cognitive, and emotional relative leisure deprivation factors. Second, conceptual reliability and distributed extraction index are shown to be appropriate for the baseline, ensuring internal consistency of the final model, and confidence and validity of all variables. In conclusion, the relative leisure deprivation measure was finally developed with a total of four factors 18 questions, confirming that all indices met the baseline and were reasonable. In the future, we hope that the standardized measure of relative leisure deprivation will be valuable in various real-world sites and academic areas so that everyone can be guaranteed a happy life in terms of leisure welfare.

Abstract
The purpose of this study is to identify the efficiency of drafts for Korean professional baseball team using the DEA efficiency analysis model. To find efficiency, the results of draft for each round of 10 KBO teams from 2010 to 2017 and the cumulative performance data of players until 2019 were used. Total 795 subjects were studied and the players who did not join in the team after the draft were excluded. For the DEA efficiency analysis, each team’s cost of round picks, signing bonuses were used as input factors, and the output factors were PA, OPS for the batter and IP, WHIP for the pitcher. Efficiency scores were derived from the CCR model, BCC model, and super-efficiency analysis model. The results of this study are as follows. 1) With ranking the efficiency through super-efficiency analysis, Nexen, KIA, and Doosan had good efficiency in the first round of batters, and Nexen, KT, and LG had good efficiency in the first round of pitchers. 2) With the top rounds (1-5) of the CCR model, Nexen, Doosan, and NC were the best efficiency teams in the batters, and Doosan, Hanwha, and SK were among the pitchers. 3) With the BCC model, Nexen and NC were the best efficiency teams in the batters, and KT, SK, and Doosan were the best efficiency teams among the pitchers. The results of this research provided feedback on the draft efficiency of teams and suggested meaningful data for more efficient decision-making.
