Long-term exposure to loud noise affects performance since it changes arousal level, distracts attention, and also is able to evoke subjective stress accompanied by negative emotional states. The purpose of the study was to analyze dynamics of subjective and physiological variables during a relatively long-lasting (30 min) exposure to white noise (85 dB[A]). Physiological signals were recorded on 15 college students during 30 min of intense auditory stimulation. Autonomic variables, namely skin conductance level , non-specific SCR number, inter-best intervals in ECG, heart rate variability index (HF/LF ratio of HRV), skin temperature, as well as respiration rate were analyzed on 5 min epoch basis. Psychological assessment (subjective rating of stress level) was also repeated every 5 min. Statistical analysis was employed to trace the time course of the dynamics of subjective and autonomic physiological variables and their relationships. Results showed that the intense noise evoked subjective stress as well as associated autonomic nervous system responses. However it was shown that physiological variables endured specific changes in the process of exposure to the loud white noise. Discussed were probable psychophysiological mechanisms mediating reactivity to long-term auditory stimulation of high intensity, namely short-term activation, followed by transient adaptation (with relatively stable autonomic balance) and then a subsequent wave of arousal due to tonic sympathetic dominance.

Purpose: This study aims to identify factors influencing the health-related quality of life among women merchants at traditional markets. Methods: Participants in this cross-sectional descriptive study included 121 women merchants. Data were collected from May 01 to June 30, 2019 using the patient health questionnaire-9 (PHQ-9), psychosocial well-being index-short form (PWI-SF), subjective health status, and HRQoL. Selected data were analyzed using descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression by applying the SPSS/WIN program 22.0. Results: The HRQoL was significantly different by age (F=5.87, p=.001), education (F=2.98, p=.022), working period (F=4.70, p=.004), exercise (t=2.20, p=.030), chronic disease (t=-2.57, p=.011), BMI (F=5.04, p=.008), depression (F=4.70, p=.004), stress (F=7.82, p<.001), and subjective health status (F=7.91, p=.001). Factors influencing the HRQoL for women merchants included BMI (β=-.35, p<.001), subjective health status (β=.33, p<.001), and stress (β=-.18, p=.021). The explanation power of this regression model was 29.8% (F=5.51, p<.021). Conclusion: BMI, subjective health status, and stress affect the HRQoL of the subjects evaluated. Therefore, there is a need for health management programs that may decrease stress, control the BMI, and improve the subjective health status of women merchants at traditional markets.

Objective: This study aimed to compare the subjective health status, physical activity index, and perceived stress rate of obese children with those of healthy children through propensity matching analysis and to use the results to help manage obese children. Design: Descriptive correlation study. Methods: This study conducted a secondary analysis using raw data from the National Health and Nutrition Examination Survey. Propensity matching (1:2) was conducted between obese and healthy adolescents. Results: The number of days of physical activity was 1.22 days for the obese adolescent group and 1.01 days for the non-obese adolescent group, which was higher in the obese group (p=0.003). The subjective health status was 3.43 and 3.81 in the obese and non-obese adolescent groups, respectively, showing a higher difference in the normal group (p<0.001). No statistical difference was observed in the perceived stress rate (p=0.871) or strength exercises (p=0.190) between the two groups. Conclusion: This study suggests the need for development measures to effectively improve youth physical activity, muscle-strengthening programs, stress management, and subjective health status in obese and normal groups.

This study was conducted to identify the major dietary patterns of Korean adult men and to examine the relationship between subjective stress perception and these dietary patterns using data from the 2014~2016 Korean National Health and Nutrition Examination Survey (KNHANES). Of the 23,080 total subjects, adult men between the ages of 19 and 64 who did not take the questionnaire or answer the questions relating to depression, and cases where the daily energy intake was less than 500 kcal or more than 5,000 kcal in the Food Frequency Questionnaire were excluded. This left a total of 3,464 subjects who were included in the final analysis. We performed a factor analysis based on the yearly mean intake frequency of 41 food groups to identify the major dietary patterns. Three major dietary patterns were identified (factor loading >0.3), including the 'Healthy pattern', 'Processed meat pattern', and the 'Alcohol pattern'. The 'Healthy pattern' was characterized by higher intake of beans, tofu, vegetable, fish, and fruits. The 'Processed meat pattern' was characterized by high consumption of processed meats and instant foods. The 'Alcohol pattern' was characterized by a higher intake of alcohol. As a response to the subject's subjective perception of stress, the most answered 'a little' according to age, marital status, occupation, income, residential area, smoking status, drinking status, and exercise status. People whose diets followed the 'Processed meat' and 'Alcohol' patterns had significantly higher scores on subjective stress perception compared to people following the 'Healthy pattern'. To manage subjective stress, it is more effective to maintain health by relieving stress through a healthy method that combines healthy eating and exercise rather than following an unhealthy diet as characterized by the 'processed meat' and 'alcohol' dietary patterns.

This quasi-experimental study was to explore the effects of back massage with Lavender essence oil on the stress response of the ICU nurses. Method: Twenty nurses were selected as an experimental group and twenty nurses were in the control group. Lavender essence oil mixed with Jojova carrier oil was used to massage the neck, shoulder, back, and low back. Massage was done three times a week for 20 minutes for 2 weeks by the massage therapist. The stress response was measured with a subjective stress score, Cortisol and IgA level in saliva. The cortisol level in saliva was analyzed by an radioimmunoassay before and after back massage. The level of IgA in saliva was analyzed by an immunoturbidimeter assay and subjective stress scores was measured by Visual Analogue Scale. The data was analyzed using SPSS 8.0 and the hypotheses were tested by ANCOVA and the Pearson coefficient correlation. Result: 1) Score of subjective stress decreased significantly after the use of back massage with Lavender essence oil. 2) Level of Cortisol in saliva did not change significantly after the use of back massage with Lavender essence oil. 3) Level of IgA in saliva increased significantly after the use of back massage with Lavender essence oil. 4) After the use of back massage with Lavender essence oil, there was significant negative correlation between subjective stress and level of IgA in saliva. Conclusion: Back massage with Lavender essence oil is an effective intervention to reduce the stress response in the ICU nurses.

Purpose: The purpose of this study was to determine the influence of job-seeking stress, career decision-making self-efficacy and self-esteem on subjective happiness of university students. Methods: The participants were 281 university students in D city. Data were collected using a structured questionnaire. The data were analyzed using SPSS/WIN 19.0 using one-way ANOVA, t-test, Pearson correlation, and multiple regression. Results: Subjective happiness showed positive association with career decision-making self-efficacy, self-esteem and negative association with job-seeking stress. Factors that had an influence on subjective happiness were monthly family income (less than two million won ${\beta}$=-.263, p<.001, between two million won and four million won ${\beta}$=-.207, p<.001), major satisfaction (very unsatisfied ${\beta}$=-.221, p<.001, satisfied ${\beta}$=.161, p=.003), gender (female ${\beta}$=-.154, p=.005), subjective health (unhealthy ${\beta}$=-.134, p=.013), and school year (sophomore ${\beta}$=-.123, p=.024). These factors explained 22.6% of the variance in their subjective happiness. Conclusion: The results of this study showed that more positive career decision-making self-efficacy, self-esteem and more negative job-seeking stress were needed for their subjective happiness. This study also indicated that economic status, major satisfaction, gender, and subjective health were very important in predicting their subjective happiness. Thus, to improve their happiness, it would be necessary to consider both intrinsic factors such as major satisfaction and extrinsic factors such as general characteristics.

Purpose: This study was conducted to determine the factors affecting a hypothetical model of testing for general hospital nurses' job embeddedness. Methods: Data were collected from August 20 to September 19, 2021, by a self-administered questionnaire answered by 428 general hospital nurses. The data were analyzed by SPSS and AMOS. Results: Nine of the hypothetical model's 12 hypotheses were supported by the data collected from all participants. The test results indicate that ego resilience, subjective career success, and recovery experience from job stress directly affect participants' job embeddedness. Nurses' work environments were reported to affect ego resilience and subjective career success, while at the same time ego resilience and subjective career success affected the participants' job embeddedness. Work-life balance was found to affect ego resilience and ego resilience affected subjective career success, and at the same time subjective career success directly affected participants' recovery experiences from job stress and job embeddedness. Of these variables, subjective career success had the strongest direct effect on participants' job embeddedness. Work-life balance affected the participants' recovery experiences from job stress, and their recovery experiences from job stress were found to directly affect job embeddedness. Conclusion: These results suggest that different management strategies to enhance hospital nurses' job embeddedness should address nurses' ego resilience, subjective career success, and recovery experiences from job stress.

The purpose of this study was to analyze mediating effect of resilience and daily spiritual experiences in the relationship of stress situations and subjective well-being of Christian college students. The subjects of this study were 157 Christian college students in a certain University which is located in Seoul, and mediating effect were analyzed through structural equation model. As a result of the analysis, first, there was a significant negative correlation between perceived stress and subject well-being. Second, resilience and spiritual experience had a full mediating effect on the relationship of perceived stress and subjective well-being. Third, in the relationship of perceived stress and subjective well-being, indirect effect through resilience has a greater mediating effect than spiritual daily experience. Implications of these results were concluded that spiritual daily experience of Christian college students is a significant variable in terms of stress and happiness. Apart from spiritual experience, however, resilience also could be a very important variable that mediates stress and happiness for Christian college students. In addition, suggestions for future research were discussed.
