This study was to investigate whether there are differences in subjective bad breath-related characteristics and psychological characteristics of sports masks printed with natural minerals compared with quarantine masks and cotton masks. The study subjects were divided into 30 people in the Sports Mask Group, 30 people in the KF Mask Group (KMG), and 30 people in the cotton mask group (CMG), and a total of 90 subjects participated in the study. It was randomly sent to use 1 mask per day and 3 masks for 3 days. The study period was conducted from October 15, 2020 to October 30, 2020. As a result of the study, there was no difference in the use of masks between the three groups in terms of bad breath health and dry mouth. However, the sports mask was superior to other masks in oral respiration and bad breath angle. As a result of analyzing psychological factors, there was no difference between the 3 groups for depression. However, in the stress factor, sports masks were superior to other masks in stress. The results of this study are valuable as suggesting the direction of use of functional masks, and we hope that they will be used as basic data for functional mask research to be studied in the future.

From July 1 to August 30, 2022, a survey was conducted targeting home training users who applied the Internet of Things (IoT). 129 people participated in the survey through non-face-to-face self-administration method. For data processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and 3-step mediation regression analysis were conducted using IBM's SPSS 21.0 program. The results of the study are as follows. First, in the relationship between the home training PPM model and direct participation in sports, ease appeared to have a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. In the mooring factors, individual innovativeness showed a complete mediating effect. Second, in the relationship between home training PPM model and direct participation in sports, usefulness showed a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. Among the mooring factors, individual innovativeness showed a partial mediating effect. Through this research, it is expected that the sports industry will contribute to the expansion of consumption expenditure and economic growth through the expansion of digital technologies such as NFT, Metaverse, and virtual/augmented reality.

This study tends to grasp the physical activity on its influences and effect s to the mental health of middle school students and we tried to look for a specific plan that will help to improve middle school students' mental health. We analyzed 36,530 students in middle school using a basic data "9th (2013) health behavior of juvenile on the online". The study is analyzed by complex sample data analysis method. The degree of euphoria recognition showed the low feeling of happiness when students exercise directly below two times rather than three times a week in the Physical Education class at school. On the other hand, the possibility of stress perception degree and suicide attempt is lowered. If the number of sports team participating is below one team, euphoria would be lowered and the limit of stress perception is high. However, the participation of one or two teams make the possibility of suicide lessens rather than students taking part in more 4 teams. In order to help middle school students reduce their stress and improve their happiness, they need to participate in sports as a regular team and join intramural games more than three times a week. In this case of the lower grade, it is considered that it is necessary for them to combine the educational program for the emotional support to control their extreme behavior.

This study was investigated the effect of aerobic exercise and chrysin supplementation on macrophage infiltration and lipolysis in high-fat diet mice. To accomplish the purpose of this study, C57BL/6 mice were fed high fat diet(60% fat diet) during experimental period. The animals were divided into 4 groups; NC (normal diet control, n=5), HC (high fat diet control, n=5), Hch(high fat diet with chrysin, n=5), and HME (high fat diet with aerobic exercise training, n=5). Exercise training was performed for 16 weeks on a treadmill running. As a result, macrophage marker, F480 and CD11c were significantly decreased in HME comparison with HD and Hch. Also, M2 macrophage marker CD11c, and lipolysis marker PRDM were significantly increased in HME compared with HC and Hch These findings suggest that regular aerobic exercise has beneficial effects to inhibit macrophage infiltration in high fat diet mice.

The purpose of this study was to compare the golf performance on transcranial direct current stimulation(tDCS). Ten collegiate golfers were participated. SAMPutt basic unit was used to analyze the kinematic data of putter head. A putting platform and a tDCS were used for putting tasks. It was performed paired t-test to compare between before tDCS and after tDCS. A significant level of .05 using SPSS 24.0. Face at aim and backswing variables of putter head were significantly different during flat putting. Impact spot of putter head was significantly different during 2° of hook slope. However, there were not significantly different others slope angle. It was found that transcranial direct current stimulation had a positive effect on kinematic variables. Based on these results, further research is needed to confirm the effect of transcranial direct current stimulation on body stability during putting task.
