Cardiovascular, respiratory and electrodermal responses to acute stress episodes modeled by combined presentation of intense white noise and performance of word recognition task with noise background were studied in 15 college students. Experimental procedure consisted in sessions with white noise, word recognition task presentation with noise background and test with noise background. Recorded physiological variables were analyzed in terms of their sensitivity to detect activation of sympathetic and parasympathetic branches of autonomic nervous system and thus reflect autonomic arousal level during shout-term stress-inducing experimental manipulations. It was shown that performance of effortful mental task with noise background elicited significant physiological responses typical for active coping behavior, namely electrodermal arousal and increased cardiovascular activity. this response profile was more profound as compared to white noise only or attending task in noise background. However, all physiological responses were mostly phasic, without long-term tonic changes, since almost all variables recovered to their initial baseline levels, suggesting that dominant autonomic mechanisms in transient acute stress episodes were of parasympathetic nature (withdrawal in stress with subsequent activation in restoration period), while sympathetic contribution was not long-lasting. Nevertheless, increased number of stressors and their longer exposure may result in higher profile of tonic sympathetic arousal and reduced functional role of vagal mechanisms in autonomic balance regulation.

Purpose: This study was done to examine the effects of assertiveness training on Intensive Care Unit (ICU) nurses' assertive behavior, job stress, communication conflict, and self-esteem toward improving their communication skills and coping. Methods: The assertiveness training program was developed to a 10-hour program consisting of 3 sessions. The goals were to understand assertive behavior and learn how to practice assertive communication in general conflict situations and/or a difficult conflict situation in the ICU. Participants were 65 nurses recruited from a tertiary teaching hospital and of these, 27 nurses completed the program. Data were collected from Jan. 30th to Mar. 28th, 2009 using a questionnaire which included demographic characteristics, assertive behaviour scale, job stress scale, communication conflict inventory-specific, and self-esteem scale. Data were analyzed using SPSS v. 14.0 for $x^2$ test and t-test. Results: ICU nurses in the experimental group had a significant increase in aspects of assertive behavior and a decrease in job stress. Conclusion: The results of the study indicate that assertiveness training is effective in increasing ICU nurses' assertive behavior and decreasing job stress through reinforcement of assertiveness behavior.

Purpose: The purpose of this study was to identify factors influencing nursing performance of clinical nurses. Methods: This was a descriptive study involving 172 nurses who worked for 6 months or longer at one general hospital in B City. The data analysis was conducted with t-test, ANOVA, Scheffé test, Pearson's correlation coefficients, and stepwise multiple regression. Results: Nursing performance of participants positively correlated with job stress (r=.16, p=.033). The factors affecting nursing performance were total clinical experience (β=.37 p<.001), salary (β=.19, p=.028), and job stress (β=.13, p=.045). These variables had a 27.2% variance to explain nursing performance. Conclusion: Based on these results, administrative and financial support are required for the development of a clinical career program, including the differentiation of salary systems of clinical nurses. There is also a need to develop and implement job stress management and coping programs.

Purpose: This study examined the effect of emotional intelligence, job stress, and communication ability on nursing performance of nurses caring for cancer patients. Methods: This is a descriptive study involving 185 nurses with an experience of longer than 6 months at K university hospital in B metropolitan city. The data was collected from March 2nd 2021 to March 31st 2021, and analyzed using the descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: The factors affect the nursing performance of participants were emotional intelligence, total clinical career, communication ability, job stress and satisfaction of current department. The total explanatory power of those variables on the nursing performance was 43.8%. Conclusion: In order to improve nursing performance, it is necessary to apply a program for improving emotional intelligence and communication ability, and for controlling and coping with job stress, considering the career of a nurse taking care for cancer patients. In addition, efficient manpower management and material support at the hospital organization level are required.

Purpose: Smoking is a way of coping with anxiety and stress. This study aimed to identify the effects of forest-thermal combined therapy on anxiety and depression in smokers who desire to quit smoking. Methods: Thirty participants were included in the study, 15 in the experimental group and 15 in the control group. Those in the experimental group participated in a three-day forest-thermal combined therapy program. The program includes forest walks, meditation and thermal therapy in the charcoal kiln. Results: Before and after the program, physiological indicators such as cortisol, heart rate variability, and serotonin anxiety level using the state-trait anxiety inventory (STAI), and stress level using the psychosocial well-being index (PWI) were measured in both groups. The differences in STAI (p=.012) and PWI (p=.006) scores between the experimental and control groups were statistically significant. However, cortisol, heart rate variability, and serotonin were not significantly different between the two groups after the program. Conclusion: These results show that forest-thermal combination therapy effectively reduces anxiety and stress in smokers. It suggests that forest-thermal therapy can potentially increase smoking cessation rates.

Objective : To investigate the sources, extent and related factors in South Korean doctors. Methods : The study subjects were 934 doctors in Taegu, Kyungpook Province, Korea(540 independent practitioners, 105 employed at hospitals and 289 residents in training). Information concerning job stress was obtained using a 9-item questionnaire. Information regarding related factors such as demographic characteristics(age, sex, marital status), perceptions on the socioeconomic status of doctors and working conditions(work time, on-call days per week) was also obtained by self-administered questionnaire during April and May, 2000. Results : Major sources of job stress included clnical responsibility/judgement factor, patient factor and work loading factor. The job stress score of residents was the highest among three groups. The score was lower in older doctors. The score was low among those who thought doctors' socioeconomic status was not good. The longer the work time, the higher the job stress score was. Multiple regression analysis was conducted to control for the mutual influence of independent variables. In regression analysis, the score of residents was higher than practitioners. Work time and socioeconomic status perception had negative effects on job stress score. Conclusion : The average job stress score of the doctors was high. Age, work type, working conditions and perceptions of socioeconomic status were found to besignificantly related to job stress score. Although the job stress of doctors is somewhat inevitable due to the nature of the doctor's job, control of work time, development of coping tools and other intervention methods are needed to reduce job stress of doctors. Further studies are required to understand the characteristics of iob stress and reduce the job stress of doctors.

This study was carried to estimate the prevalence of obesity and to investigate the relationship between stress and obesity in children. The subjects were 508 children, who were randomly selected from the fifth and sixth grade at nine elementary schools in Kangnung. The height, body weight, waist and hip circumferences and body fat(%) were measured and the levels of stress were assessed by a questionnaire consisting of the following 3 domains ; 4 items for personal factors, 11 for home, and 18 for school. The prevalence of obesity in male and female children greatly varied by the indices from 2.5% and 1.7% when judged by BMI, 9.5% and 4.0% by obesity index, and 29.7% and 34.4% by body fat(%). The stress scores from personal(47.1%) and school (47.9%) factors were higher than the stress score from home(38.5%). The stress score from personal factors of female children is significantly higher than that of male children, but the stress score from home of female children is significantly lower than that of male children. The personal stress score and the total stress score of obese female children were significantly higher than those of non-obese female children. In male children, the obesity index(%) or body fat(%) have a significant positive correlation with the stress scores from over-expectation of parents, a lack of conversation with family, examinations, discontent about school, teacher's partiality to students, and sexual curiosity. The female children have a significantly positive correlation of obesity index (%) or body fat(%) with stress scores from appearance, quarrels of parents, and inferiority complex to brothers or sisters. These results suggested that counselling and education about not only balanced diet but also the strategies for actively coping with stress are needed to prevent and treat childhood obesity.
