Objectives: This study aims to examined whether physical activity prevent the negative effect of psychological stress on cardiovascular reactivity by reducing stress induced sympathetic output and preventing norepinephrine depletion negative psych-affective responses. It is assumed that physical activity reduces the magnitude of cardiovascular responses and psychological responses to stress which threaten individuals' physical and mental health. The result of investigating the effect of physical activity on reducing negative physiological and psychological responses would suggest useful information health for practitioners who want to prevent stress-induced diseases, especially coronary heart disease. Methods: participants of this study were 30 students (10 males & 20 females), whose mean age was 21.30 (SD=2.29). Fifteen students (5 males & 10 females) were assigned for in each group, treatment and control groups. They were interviewed and given a survey that included a consent form, demographics sheet and psychological tests, such as State-Trait Anger Expression Inventory and State-Trait Anxiety Inventory. Before the application of psychological stress, participants in treatment group were going through with a course of physical exercise, running on treadmill 15minutes, while participants in control group were not physically active. After exercise, there was 15 minutes resting period before applying cognitive stress. During the experiment, all participants performed challenging cognitive tasks for 20minutes in situations that were designed to experience learned helplessness and measured their cardiovascular reactivity including blood pressure and heart rate every 5 minutes, until 10 minutes after finishing the application of psychological stress(recovering state). In the end of experiment, they were given some psychological test again. Results: Heart rates of exercise group were significantly higher than non-exercise group, especially, five minute after applying cognitive stress and at the end of recovery, in other word 10 minutes after stressful event. Systolic blood pressures of exercise group were lower than those of non-exercise group during the stressful event, but this differences in borderline level of significance. state anger level of exercise group decreased even experiencing stress, while those of non-exercise group increase. And state anxiety level of exercise group decreased in borderline level of significance. Conclusion: This study reiterate health benefits of physical activity and suggest that regular moderate exercise may regulate cardiovascular reactivity and psycho-affective responses from stress by reducing stress induced sympathetic output.

The result shows that the households which had a low economic status and high economic stress from the objective viewpoint participated in more economic activities. Their reactions were to decrease the overall expenditure through reducing the expenditure rather than to manage the asset effectively through re-employment or to inaugurating a business. Third, I analyzed situational factors, economic stress, and economic coping strategy in order to compare relative contributors to psychological well-being through using regression. At the third phase in the process of analysis, the socio-psychological factors appeared to be significant factors contributing to psychological well-being. Regarding the stress caused by income expenditure increased, when elderly households were more concerned about reducing expenditure and re-employment, their feelings of depression increased.

Irregularity of meal times and skipping breakfast were positively correlated with tiredness in lessons and befor school. Consumption of some foods was related to perceived tiredness. High sugar or fat containing ice-cream, hamburger of fizzy drinks in boys, and crisps and cookies in girls were positively associated with tiredness. Whereas beans and mushrooms were negatively associated with tiredness in girls. Life stress(by scholastic problem and personal problem) of adolescents was positively related to tiredness. The contribution of stress to tiredness was much greater than of food behavior according to multiple linear regression .There was no relationship between nutrients intake and tiredness in lessons and before school which were more strongly influenced by stress, whereas the relationship was found at weekend without influences of stress.

As the number of foreign workers increases in Korea, people's interest in their adaptation to this society has also increased. The purpose of this study was to investigate the effect of a forest-healing program on foreign workers' cultural adaptation stress and psychological wellbeing. The experiment was conducted in a recreation forest located in Hongcheon-gun, Gangwon-do. The subjects who participated in this study included 40 foreign workers (16 males, 24 females). The experiment was conducted for three days and two nights from June 26 to 28, 2019. The forest healing program was composed of activities that can enhance immunity and restore physical and mental health by utilizing various healing environmental factors such as landscapes, sunlight, anion and oxygen in forest. The independent sample t-test was conducted to examine changes in cultural adaptation stress and psychological well-being before and after the program. The collected data were analyzed using SPSS 18.0 program. As a result, cultural adaptation stress was statistically significantly reduced in sub-factors including discrimination experience, language conflict and legal status. Psychological wellbeing improved in all the surveyed sub-factors such as self-confidence, ego, immersion, and joy.

Pilots are indispensable and central to the aviation industry, with the relevance of their psychological stress and resultant human errors increasingly recognized as critical. This study aims to meticulously explore the interrelations between psychological stressors and associated factors among helicopter pilots, assessing the consequent effects on potential accidents and incidents. The study comprised active pilots from domestic helicopter airlines, with data collated through both focus group interviews (FGI) and comprehensive surveys. These data were subsequently analyzed using SPSS and AMOS for structural equation modeling. The results reveal that heightened psychological stress in helicopter pilots correlates with an increased incidence of human errors, which in turn, elevates the likelihood of potential safety incidents. Based on these findings, it is proposed that interventions designed to mitigate psychological stress among pilots could significantly reduce human errors and enhance overall aviation safety. This research provides crucial insights into specific ways to improve the operational conditions for helicopter pilots and strengthen the safety protocols within the aviation industry.
