Purpose: The aim of this study was to examine the effects of a yoga program on perceived stress, stress response and heart rate variability in professionals. Methods: The research design was a quasi-experimental intervention study. The participants were 47 adults with professional jobs consisting of an experimental group with 23 adults and a control group with 24 adults. The duration of the yoga program was eight weeks from July 4 to August 30, 2012. Results: There were significant decreases in the stress response score after the yoga program. No significant changes in perceived stress and heart rate variability were observed between the experimental group and control group. However, there were significant decreases in perceived stress, stress response scale, and heart rate variability for some participants whose stress levels were high. Conclusion: An eight-week-long yoga program could be considered as an intervention to decrease the stress response of professionals even though it might not reduce their perceived stress and heart rate variability. To further analyze the effects of a yoga program in professionals, changes in intervention strength (such as longer periods and frequency) and the development of physiological measures, which would show the co-relationship between perceived stress and physiological response, are necessary in future studies.

This study examined the effects of social comparison orientation and stress coping styles on job-seeking stress experienced by university students. The participants of this study were 324 junior and senior students (151 males and 173 females) from six universities located in Seoul who were preparing for employment. They were asked to respond to a written questionnaire to measure research variables for the Job-Seeking Stress Scale, the Social Comparison Orientation Scale, and the Ways of Coping Checklist. The data were analyzed by means of descriptive statistics and a hierarchical multiple regression. The major findings of this study were as follows. First, social comparison orientation had a positive effect on job-seeking stress of university students, revealing that students with a high level of social comparison orientation were more likely to experience job-seeking stress. Second, both emotion-alleviation coping style and wishful thinking coping style increased level of job-seeking stress. In addition, problem-focused coping style had a negative influence on job-seeking stress, whereas social support seeking coping style had no significant effect on it. The results suggested that it would be possible to reduce job-seeking stress of university students by changing either social comparison or stress coping style.

This study analyzed the effect of young farmers' stress on farming satisfaction and Intention to Leave the Farming. The analysis targets young people living in rural areas and engaged in agriculture among 4H members nationwide. As a result of the analysis, there were significant differences in stress of young farmers according to the characteristics of the investigator, and there were differences according to family composition and community activities. In addition, family stress and social stress showed significant results according to the type of young farmers, community activities, and economic stress according to the type and family composition of young farmers. And the stress of young farmers had a positive (+) effect on Intention to Leave the Farming, and family and social stress also had a positive (+) effect on Intention to Leave the Farming. In addition, the stress of young farmers affected farming satisfaction, and family stress and social stress also had a negative (-) effect on farming satisfaction. Therefore, efforts will be needed to improve farming satisfaction and reduce Intention to Leave the Farming by reducing stress among young farmers.

Background and objective: Recreation or activities in forest are regarded as therapy. Many forest therapy programs have been developed and assessed in the domestic. This study was conducted to investigate the effect of the forest therapy program on academic and job-seeking stress in college students. Methods: Thirty five subjects were selected as the experimental group and 25 as the control group, and 29 subjects in the experimental group and 11 in the control group participated in the follow-up test to verify the persistence of stress reduction effects. The forest therapy program was carried out once a week for 2 hours each from September 4 to December 4, 2018, adding up to total eight sessions. Results: The experimental group showed statistically significant reduction in both academic stress and job-seeking stress, whereas the control group did not. For the persistence of the forest therapy program, the experimental group did not show a statistically significant difference between the posttest and the follow-up test, and thus the stress reduction effect was maintained. Conclusion: This study proved the reduction of academic and job-seeking stress in forest therapy programs and the persistence of the stress reduction effect of the forest therapy program. The result is consistent with the Stress Recovery Theory (SRT) that shows the stress reduction effect of nature. In addition, it has significance in that it has verified that the program using the forest on campus can reduce stress of most college students.

Purpose: This study was to identify the level of job stress and turnover intention and to explore the impact of job stress on turnover intention among emergency room (ER) nurses. Methods: With a correlational survey design, 155 emergency room nurses were recruited in D metropolitan city. Data were collected using a structured questionnaire including ER-related job stress, turnover intention, and subjects' characteristics from March 18 to March 26, 2013. Results: Overall mean score of job stress was $284.34{\pm}40.60$, indicating higher level of job stress. The highest job stress category was conflict related inside the hospital and transportation team, and followed by matters related the patient and the guardian, conflicts with doctors, and heavy workload. The average score of turnover intention was $15.41{\pm}3.68$, indicating higher intention to quit their jobs. There was a moderate level of positive correlation between job stress and turnover intention (r=.44, p<.001). Turnover intention was high when ER nurses had higher job stress (${\beta}$=.38), were female (${\beta}$=.22), and wished to move to another department (${\beta}$=.17). Conclusion: The most important factor of turnover intention was job stress among ER nurses. Strategies to lower turnover rate for ER nurses should be focused on seeking ways to reduce their job stress.

To investigate applicability of the reference stress approach as simplified inelastic stress analysis to estimate local creep rupture, detailed finite element stress analyses of a T-piece pipe with different inner pressure and system loading levels are performed. The reference stresses are obtained from the finite element (FE) limit analysis based on elastic-perfectly-plastic materials, from which the local reference stress for creep rupture is determined from R5. The resulting inelastic stresses are compared with elastic stresses resulting from linear elastic FE calculations. Furthermore they are also compared with the stresses from full elastic-creep FE analyses. It shows that the stresses estimated from the reference stress approach compare well with those from full elastic-creep FE analysis, which are significantly lower than the elastic stress results. Considering time and efforts for full inelastic creep analysis of structures, the reference stress approach is shown to be a powerful tool for creep rupture estimates and also to reduce conservatism of elastic stress analysis significantly.

Purpose: This study was conducted to examine the relationship between stress and quality of life of family caregivers of patients with lung cancer. Methods: From April 18 to May 4, 2009, data were collected using self-report questionnaires with 95 family caregivers of lung cancer patients in G cancer center. The data were analyzed using descriptive statistics, t-test, ANOVA and pearson's correlation coefficient with SPSS 14.0. Results: The mean score of the stress level was 27.5 (SD=14.77). The mean score of the QOL was 73.0 (SD=17.86). The stress level of family caregiver showed significant difference according to gender (psychological stress p=.011, total level of stress p=.042) and availableness of second caregiver (physical stress p=.023, psychological stress p=.035, total level of stress p=.001). The QOL of family caregivers showed significant difference according to daily caring (positive adaptation p=.045) and financial burden on treatment expense (positive adaptation p=.004, total quality of life p=.043). The negative correlation was found between stress and QOL of family caregivers (r=-.67, p=.032). Conclusion: These results indicate a need to develop nursing intervention programs for family caregivers to reduce stress and improve QOL.

Purpose: This study was done to identify relationships among post-traumatic stress (PTS), job stress and turnover intention in emergency department (ED) nurses. Methods: Participants were 250 ED nurses who had worked for one month or longer in the ED one of three university hospitals or seven general hospitals in Daegu City or Gyeong Buk Province in Korea. Structured questionnaires were used to measure PTS, job stress, and turnover intention of participants. Data were analyzed using descriptive statistics, one-way ANOVA, path analysis, and stepwise multiple regression with the SPSS program. Results: There were significant relationships between PTS, job stress and turnover intention. PTS influenced turnover intention directly and was indirectly mediated by job stress. The experience of traumatic events influenced PTS, job stress, and turnover intention. Indirect experience of traumatic events in the ED was an important predictor, explaining 20.1% of PTS in high-risk post-traumatic participants. Conclusion: PTS can be an important factor for job stress and turnover intention. The direct and indirect experience of traumatic events can influence PTS, job stress, and turnover intention in ED nurses. Based on these results, strategies for managing PTS and relating job stress are recommended to reduce turnover intention in ED nurses.

In this study, a graphical automatic system is developed in order to investigate the stress redistribution of structural members in a steel cable-stayed bridge. The generalized Maxwell model is selected for stress relaxation estimation, and it is carefully verified and applied to all the cable members of a steel cable-stayed bridge to investigate its stress relaxation. A set of stress relaxation parameters in all cables is determined using the fmincon optimization function. The stress redistribution of the steel cable-stayed bridge is then analyzed using ABAQUS. To shorten the investigation time, all the aforementioned phases are built up to be an automatic system. The automatic system is then employed to investigate the effect of cable cross-section areas and girder spans on stress redistribution. The findings from these studies show that the initial tension in the cables of a steel cable-stayed bridge should be kept to less than 55% of the cable's ultimate strength to reduce the effect of cable stress relaxation. The cable space in a steel cable-stayed bridge should be limited to 15,000 mm to minimize the effect of cable stress relaxation. In comparison to other structural members of a steel cable-stayed bridge, the girders experience a significant stress redistribution.

Increasingly nursing science is embracing the concepts and methodology derived from psycho-neuroimmunology. It has been previously shown that stress increases and immune function declines in students undergoing examinations. To date, however, no many studies have been reported on stress levels, immune function and interventions in Korean students undergoing their first clinical nursing rotation. It was proposed that nursing students during their first clinical rotation experience increase in stress because of the novelty of the situation and their lack of clinical knowledge. It was also hypothesized that biofeedback and progressive relaxation, methods of self-regulation of involuntary autonomic nervous system responses, would reduce the stress response. The purpose of this study is to test the effectiveness of progressive muscle laxation using biofeedback The effectiveness of the experimental methods was tested by measuring the degree of symptoms of stress (SOS) and the values of ephinephrine, pulse rate, blood pressure and natural killer cells. The subjects of this study were thirty nursing students divided into two groups: experimental group was progressive muscle relaxation group using biofeedback and control group. This study was conducted for 8 weeks of clinical practice. Biofeedback training was done by software developed by J&J company (1-410 form for progressive muscle training). Progressive muscle relaxation training according to Jacobson's Theory was done by messaged word from biofeedback. The data was analyzed using Chronbach' ${\alpha}$ and t-test of the SPSS program and the significance level of statistics was 5%. The results of the study were : 1) The progressive muscle relaxation training using biofeedback was effective for the reduction of symptoms of stress(t=-4.248, p<.001) under clinical practice stress conditions. 2) The progressive muscle relaxation training using biofeedback was not effective for the values of epinephrine(t=-1.294, p=.206). 3) The progressive muscle relaxation training using biofeedback was effective for the reduction of systolic blood pressure (t=-2.757, p=.01). 4) The progressive muscle relaxation training using biofeedback was effective for the reduction of diastolic blood pressure (p=-2.032, 0=.05). 5) The progressive muscle relaxation training using biofeedback was not effective for the reduction of pulse rate(t=-15, p=.988). 6) The progressive muscle relaxation training using biofeedback was effective for the maintenance of natural killer cells (t=2.381, p=02). The first clinical rotation for student nurses is a stressful experience as seen by the rise in the SOS in the control group. Biofeedback using progressive muscle relaxation were effective in preventing the rise of symptoms of stress and the blood pressure means when comparing the pre to post clinical experience, The mean natural killer cell count was depressed in the control group but not significantly different in the experimental groups, It is proposed here that stress via the hypothalamic - pituitary - adrenal axis suppressed the NK cell count whereas the relaxation methods prevented the rise in stress and the resulting immune depression. We recommend relaxation techniques using biofeedback as a health promotion technique to reduce psychological stress. In summary. the progressive muscle relaxation training using biofeedback was effective for the reduction of symptoms of stress under clinical practice stress conditions.
