During the COVID-19 pandemic, social distancing affected daily life and leisure activities, including forest recreational activities. This study identified changes in people's participation in forest recreational activities and factors affecting their participation. It collected data from 1,000 samples through an online survey and analyzed it using a binary logit model with interaction terms. It was observed that there were decreases in the participation in visits to urban parks and green areas, outdoor activities in forests and mountains, and trips to mountain villages after the COVID-19 outbreak. People in their 40s, 50s, and 60s were more likely to decrease their participation in all kinds of forest recreational activities than those in their 20s. Moreover, higher household income earners were more likely to decrease their involvement in outdoor activities in forests and mountains. With respect to the place of residence, the residents in the Seoul metropolitan area were less likely to decrease their participation in trips to mountain villages than those outside this area. Thus, this study suggests that online forest recreation information services and forest management are needed to meet the demands of forest recreation for young generations and diversify the function of forests and rural areas as a safe leisurely space.

Stress has become one of the largest health risk to shorten the life time of health. Accordingly, in order to increase the life time of health, stress relief can be very important. Many social expenses and economic commitment have been inputted for this purpose, but their effectiveness compared to the current situation is not very high. In this paper, we carried out an identification work of rain sound which is similar to the white noise that can stabilize the body and mind of the person by analyzing the variations of 3rd formant frequency bandwidth. Also, for relieving stress, the sounds of rain that is easily accessible at a relatively among the sounds of nature instead of consuming a lot of money and time were selected for solving these problems. In addition, we identified the effectiveness of the stress relief about the sound of rain and research on whether there is a difference between men and women in their 20's or not was performed. Finally, we discussed the personal - adjusted rain making to maximize the effectiveness of stress relief.

This study was done to investigate the effect of stress on appetite and eating habits, and other health-related behaviors. The subjects of this study consisted of 188 males and 224 females in Ulsan area. The results were as follows: When stressed, 56% (n = 231) of the subjects experienced a change in appetite and of these, 32% (n = 132) experienced an increased appetite. Stress-induced eating may be one factor contributing to the development of obesity. There was a gender-specific response to stress in which women are more likely to use food to deal with stress, whereas men are more likely to use alcohol consumption or smoking. It was found that types of stressors were individual (52.9%), social (50.7%), family relations (34.5%), work demands (34.2%) and physical environment (32.3%). Stress-induced symptoms of the subjects were anxiety (38.3%), headache (36.7%) and neck or shoulder aches (36.2%), and females experienced those symptoms more than males. Those older than 50 years had a higher eating habit score and lower stress score compared with younger subjects. There were significant differences between sex, age, occupation, family type, BMI, exercise, sleeping hours and eating habits or stress level. This study may be helpful in advancing findings in this area to better provide health professionals with appropriate counseling tools to improve the health of all individuals.

In previous studies, the dynamic exercise equipment just focused on the trunk stabilization exercise. However, our study is targeted at evaluation for the impact on the postural balance of those researches. Twelve male and twelve female subjects were volunteered for the balance training using this system. They had no medical history of backpain for the past six months. Trunk Stability and postural balance training was performed for 15 minutes a day, three times a week duing four weeks. To evaluate characterization of the postural balance using Balance System SD, Evaluation consist of the postural stability test and the postural limit test. As a result, this training with 3D dynamic exercise equipment help subjects improve the postural balance. These results are expected for using basic materials to the elderly with a high risk of falling and trained athletes needed to be a postural control.

Social interaction becomes increasingly complicated, sophisticated and specialized. Popular methods of communication has expanded from face-to-face to the use of IT media, as the amount of needs for remote communication increases rapidly as well as the scope of the contents of communication. The purpose of this study is to empirically examine the relationship between the use of IT media and the level of interpersonal trust, and further examine the differences in interpersonal trust across the use of different IT media. A questionnaire survey was performed against 193 individuals in the age group between 20s and 40s, which is considered most active group of IT media. According to a series of regression analysis, the frequency of mediated information exchange is found to be correlated to the level of interpersonal trust. The effect of the amount of time spent with the media was not significant. We also found that the effects on interpersonal trust differed across the use of different types of communication media.

This study investigates the effects of instrument-assisted soft mobilization (IASTM) and manual myofascial release (MFR) on the muscle activity of the biceps brachii. This study was conducted on 10 men and women in their 20s, and all subjects participated in the experiment for 3 days and measured muscle activity of the upper forearm muscles. On the first day, the muscle activity value was measured before the intervention, and the remaining two days were measured for muscle activity after the intervention of each manual therapy in a random order. All muscle activity values were compared and analyzed through the dependent t test and the independent t test. The before and after comparison of muscle activity values before and after each intervention was verified by performing the dependent t test and comparing the values of muscle activity between groups between each intervention after intervention by performing an independent t test. According to the results of this study, both interventions significantly increased muscle activity of the biceps brachii before and after intervention, and there was no significant difference in muscle activity values between groups after intervention. Therefore, both manual therapy (IASTM, MFR) are thought to be effective in improving neuromuscular control ability.

The purpose of this study is to measure the trust and distrust perception of our society about science and technology. In addition to examining trust and distrust in science and technology, we also looked at trust and distrust in geoscience technology. In addition, by comparing the levels of trust and distrust in science and technology and geological resource technology, the implications for improving the reliability of geological resource technology are drawn. This study surveyed male and female office workers over 20 years of age working in the Seoul metropolitan area on the trust and distrust of science and technology. The results of this study show that respondents showed above-average trust in science and technology and geological resource technology. According to the gender or age of respondents, there was no difference in trust and distrust of science and technology and geological resource technology. As a result of examining the difference between trust and distrust in science and technology and geological resource technology, respondents showed higher trust scores in science and technology than geological resource technology. These results suggest that current communications activities on geological resources should be more active and diversified.

The present study explored how 1) individuals' perception about attributes of exercise/fitness apps and 2) their motivation for exercise/fitness behaviors influence perceived usefulness and usage of the apps. A survey of 323 males and females in their 20's and 30's revealed that attributes of apps that satisfy their basic psychological needs are crucial in promoting perceived usefulness and usage of the apps. Participants were more likely to perceive exercise/fitness apps useful as they perceive them having more attributes related to autonomy and competence. The perception regarding relatedness attributes did not have the main effect on perceived usefulness but showed an interaction effect with relative autonomous motivation. This convergence study which examined health apps from the perspectives of psychology and public health provides practical implications to development and evaluation of health apps.
