Because of the COVID-19 epidemic, many countries have made the obligation to wear masks normal. Wearing masks in public places has become a must. At present, wearing a mask to participate in sports makes it very common. People seek to gain health through exercise but ignore the potential respirato-ry health threat. That is, wearing a mask will cause a decrease in oxygen content in the body. This neg-ative impact becomes more prominent as the wear-ing time and oxygen consumption increase. To pro-tect people from viruses and enjoy a healthy life. This paper proposes a breathing pattern that im-proves blood oxygen saturation while wearing a jogging mask and walking. Namely, shouting breathing pattern. Use a pulse oximeter to measure the blood oxygen saturation of running at different speeds and compare the normal breathing pattern and the shouting breathing pattern. The results show that the shouting breathing pattern has a sig-nificant improvement in the blood oxygen satura-tion of low-speed walking and medium-speed jog-ging.

In an effort to obtain preventive, diagnostic and therpeutic medical and exercise training information of rheumatoid arthritis as well as to provide pertinent data to be used in development of exercise program for the management of rheumatoid arthritis, this study was conducted by using literature review. Because RA is a disease that involves both joints and muscles, its activity in the different functional classes influences the patient's ability to exercise. A patient in Functional Class 1 may perform any type of exercise because the disease involvement has not yet reached major importance. Exceptions may include hard physical exercise, running, and individual racket sports. In almost all cases, bicycle exercise is possible. Patients in Functional Class 2 and a few in Class 3 can perform most types of exercise (especially cycling, walking, heated pool exercise and even jogging) in low activity phases of RA. Although a few patients in Functional Class 3 can walk, jog, and perform similar types of exercise, most persons in this class can swim or exercise on a bicycle if the type of exercise, its intensity, and its range of motion are modified according to the patient's anatomic and pathologic conditions. Most patients in Functional Class 4 are not able to carry out complicated movements. We conclude that physical training for persons with RA has physical, psychological, and social consequences that are clearly beneficial. We recommend training be one part of the many involved in the complicated treatment of RA.

The effects of job stress factors on psychological job stress and job satisfaction levels of school dietitians were evaluated. Questionnaires were distributed to 163 elementary school foodservice dietitians in the Seoul and Incheon area. Statistical data analysis was completed using the SPSS program. The highest stress factor was the importance of the job followed by role ambiguity, autonomy and identity, communication and participation. When dealing with job stress, the subjects showed improved and positive behaviors when communicating and participating with each other. The analysis of the relationships between job stress factors and job satisfaction revealed that the importance of the job had a negative effect on jog satisfaction. while role conflict and overload, personal relationships, and experience accumulation had positive effects. Ample occupational experience and background had highly positive effects on school dietitians' job satisfaction level whereas negative results were shown concerning circulated appointments(p<0.01). Based on these results, we suggest that role conflict and overload should be reduced in order to lower job stress levels and enhance job satisfaction levels.

Purpose: The purpose of this study was to investigate the effects of appearance stress and appearance management behavior on job-seeking stress among male university students. Methods: The participants of this cross-sectional and descriptive study were 158 male students attending a university in K Province who completed a self-report structured questionnaire. The survey period was from September 19th to November 9th, 2017. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, correlation and multiple linear regression analyses with the SPSS statistics 23 program. Results: Job-seeking stress showed significant differences according to BMI (F=2.55, p=.042) and pocket money (F=3.08, p=.049). The results of the regression analysis showed that grade (${\beta}=8.93$, p=.008), pocket money (${\beta}=-5.11$, p=.029), appearance stress (${\beta}=.52$, p<.001), and appearance management behavior (${\beta}=.25$, p=.001) were significant factors affecting jog search stress. Conclusion: The findings of this study suggest that variables such as grade, pocket money, appearance stress, and appearance management behavior significantly explain job-seeking stress among male students in college. Therefore, it is necessary to develop a program to reduce job-seeking stress for senior male students who are preparing for employment before graduation. In addition, when organizing a program to reduce job-seeking for male university students, it is necessary to help them have a more positive evaluation of their appearance and pursue proper appearance management behaviors.

Root caries is very frequently developed on exposed root surface after periodontal surgical treatment. In order to determine the anti-caries effect of Nd : YAG laser irradiation on periodontally exposed root surface, 40 mandibular molar teeth that had been extracted due to excessive periodontal destruction were used as the experimental teeth. All teeth were treated by the same procedure as conventional periodontal root treatment, ie thorough scaling, root planing and root conditioning with tetracycline HCl(100mg/ml, 5min.). Within middle one third of root, mesial half surface(20) or distal half surface(20) was randomly irradiated at various power of 1.0W, 2.0W, 3.0W and 4.0W for 60 seconds by non-contact(5mm) delivery of a pulsed Nd : YAG laser(EN.EL.EN060, Italy). The microhardness was measured by Vikers microhardness tester(Wilson, USA) at 2mm/second of jog speed under 100gm load. The difference of microhardness between irradiated side and non-irradiated side was statistically analyzed ANOVA and Duncan's method. Following results were obtained ; 1. The microhardness(Knoop hardness number) was significantly higher in laser irradiated surface than non-irradiated surface(p<0.05). 2. There was no significant difference in microhardness between experimental groups classified by different laser power(p>0.1). The results suggest that Nd : YAG laser irradiation on exposed root suface after periodontal therapy may inhibit the root caries development by enhancing surface microhardness.
