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.

A local festival is to be an essential element for the revival of regional economy and marketing since the management concept have introduced in the local government. Each local government is trying to achieve a maximum of efficiency at short period of time. But, most festival are each similar and common. In Asancity, it was holding the 'Great Admiral Yisunsin Festival' every year in April. It has grown into a representative historical figure festival nationally, but can't get over the limitation of historical figure festival. For differentiation from other festivals, The Asancity developed a online game in collaboration with hoseo university game engineering. The e-sports competition with this game was held, as a result, Many youths whose are a neglected class of people on the festival came in the festival and this e-sports competition has become benchmark for many local governments.

Is university restructuring for 'reinforcing university education quality and competitiveness of higher education'? The fundamental problems of the on going university restructuring becomes crisis of university and moreover, Sports Related Departments faces huge crisis. This research analyzes university crisis and progress of Sports Related Departments. After conducting discussion about a directivity of Physical Education in university with a focus on role and direction of 'Physical Education' which is for realization of 'University''s ideal, Sports Related Departments proposed four practical tasks, which is for preventive improvement, not for prescriptive improvement. First, Effort to establish academical identity. Second, characterization strategy for each different region and university. Third, Reforming of Sports Related Departments related with prospect of the labour market. Last, Drawing up a plan for establishing Sports Related Departments' united system.

The purpose of this research was to examine the effect of dance sports for twelve weeks on physical self-efficacy in post-menopausal depression obese women. A total 38 women participated in this study, and they were divided into three groups: mild-depression group(n=9), light-depression group(n=14) and control group(n=15). For the exercise program in this study, a dance sports program performed at an intensity of heart rate reserve 50~80%, 60 minutes of exercise time, and the frequency of 3 times a week. Physical self-efficacy for mild-depression group after 12-week dance sports program was significantly increased compared to before the exercise. Although light-depression group and control group didn't show significant increase in physical self-efficacy, dance sports is expected to act positively on mental stability, such as depression and hope used as an effective tool to improve the quality of life. Furthermore, we expect a convergence is achieved between the sports science and medical research sectors.

The purpose of this study is studying the relationship among experience choice, experience effect and experience satisfaction of marine leisure sports for the vitalization of marine leisure tourism. After preparing a questionnaire, investigation and analysis were done by visiting Boryeong area. The result of the study is as following. First, it was found that the major cause of choice in marine leisure sports has positive impact on choice satisfaction. Second, it was found that the major cause of choice has positive impact on experience effect. Third, it was found that the choice satisfaction in marine leisure sports has positive impact on experience effect. Fourth, it wa s found that the marine leisure sports visitors like motor boat, banana boat and yacht experience. Fifth, it is suggested that an equipment rental desk, safety facilities and marine leisure experience facility included in a marine leisure experience center to be built.

The purpose of this study was to analyze the sports ethics awareness of college student athletes. To this end, data was collected from 312 college student athletes. The collected data were analyzed by descriptive statistic and chi-square analysis by the experience of college student athlete's intentional defeat, recognition of intentional defeat, cause of match-fixing, and necessity of sports ethics education. The conclusions are as follows. First, 7.1% of the college students had experienced losing intentionally. Second, 16.3% of the college student athletes did not perceive intentional losses irrelevant to gambling as match-fixing. Third, the college student athletes perceived that the causes of match-fixing included illegal pursuit of profits, environmental factors, human relationships, lack of education, etc. Fourth, 8.1% of the college student athletes viewed that sports ethics education is necessary. This study can be used as a basic data of sports ethics education for student athletes and it is expected to grow as a student player who can maintain moral character.

The purpose of this study was to investigate the structural relationship between advertising attributes, advertising attitude, brand image, and purchase intention of sports brand on SNS. For this purpose, 250 valid samples from the convenience sampling method were used as the final analysis data. Entertainment, information, and credibility among ad attributes had a positive effect on SNS users' advertisement attitude toward sport brands, and irritation has a negative effect on ad attitude. The ad attitude formed by the advertising attributes positively affected the image of the sports brand and the purchase intention. Brand image had a positive effect on purchase intention. The results of this study may be helpful to maximize SNS advertising effect of sports brands and to identify some important factors that can affect direct purchasing behavior of sports majors, one of the target groups of companies promoting sports brands using SNS.

As composite materials are used in many applications, the modern world looks forward to significant progress. An overview of the application of composite fiber materials in sports equipment is provided in this article, focusing primarily on the advantages of these materials when applied to sports equipment, as well as an Analysis of the influence of sports equipment of fiber-reinforced composite material on social sports development. The present study investigated surface morphology and physical and mechanical properties of S-glass fiber epoxy composites containing Al₂O₃ nanofillers (for example, 1 wt%, 2 wt%, 3 wt%, 4 wt%). A mechanical stirrer and ultrasonication combined the Al₂O₃ nanofiller with the matrix in varying amounts. A compression molding method was used to produce sheet composites. A first physical observation is well done, which confirms that nanoparticles are deposited on the fiber, and adhesive bonds are formed. Al₂O₃ nanofiller crystalline structure was investigated by X-ray diffraction, and its surface morphology was examined by scanning electron microscope (SEM). In the experimental test, nanofiller content was added at a rate of 1, 2, and 3% by weight, which caused a gradual decrease in void fraction by 2.851, 2.533, and 1.724%, respectively, an increase from 2.7%. The atomic bonding mechanism shows molecular bonding between nanoparticles and fibers. At temperatures between 60 ℃ and 380 ℃, Thermogravimetric Analysis (TGA) analysis shows that NPs deposition improves the thermal properties of the fibers and causes negligible weight reduction (percentage). Thermal stability of the composites was therefore presented up to 380 ℃. The Fourier Transform Infrared Spectrometer (FTIR) spectrum confirms that nanoparticles have been deposited successfully on the fiber.
