Purpose: The present study was intended to assess stress, depression and fatigue of nurses working for university hospitals and to reveal its association with the type A behavior pattern. Method: The self-administered questionnaires were given to 810 nurses employed in 4 participating hospitals located in Daejeon City. The questionnaire items included sociodemographic, job-related, and the type A behavior patterns as independent variables and the PWI, SDS and MFS as dependent variables. Result: The proportion of the type A behavior pattern was 24.3% of subjects, in the degree of stress, high risk stress group was 87.0%, in the degree of depression, normal group was 60.9%, in the degree of fatigue, high risk fatigue group was 48.6%. The degree of stress, depression, and fatigue were significantly higher in the type A behavior pattern group then the type B behavior pattern group. The type A behavior pattern was significant positive correlation with stress, depression, and fatigue. The degree of stress(OR=1.2, 95%CI=1.167-1.262), depression(OR=1.1, 95%CI=1.11-1.17) and fatigue (OR=1.1, 95%CI=1.04-1.06) were significantly higher for the type A then the type B behavior pattern group. Conclusion: The degree of stress, depression, and fatigue were significantly higher in the type A then the type B behavior pattern group.

Purpose: The purpose of this study was to investigate the depression, anxiety, stress response and self-care, to analyze the correlation among depression, anxiety, stress response and self-care by gender, and to determine factors associated with self-care in diabetic patients. Method: The subjects of this study were 103 participants with diabetes mellitus. Data were analyzed by chi-square test, t-test, Pearson correlation coefficient and multiple regression analysis by using SAS program. Result: Items for self-care evaluation by gender were significant differences in hospital visit, hypoglycemia preparation, proper hygiene, taking a rest, foot injury check, drinking, and smoking. The female patients are more likely to have higher self-care score than the male patients. However, there were no differences in depression, anxiety and stress response by gender. In male patients, there were positive correlations between the degree of depression and stress response, the degree of anxiety and stress response. In female patients, there were positive correlations between the degree of depression and stress response, the degree of anxiety and stress response. In multiple regression analysis, gender and experienced admission is associated with self-care. Conclusion: We should consider integrated approaches for psychological problems in the management of diabetic patients.

The release of residual stress by mechanical loading and unloading is often performed in the fabrication of box structure fur steel bridge. The proper degree of loading and unloading is significant at release method of residual stress by mechanical loading because that degree is changed by material and geometric shape of welded structure. Therefore, the simulation model that could exactly analyze the release of residual stress by mechanical loading is to be necessary. In this study, the non-linear behavior of weldments under external loading and unloading, such as the decrease and increase of structure stiffness, was investigated by monitoring of nominal stress and strain. Tensile loading and unloading test and the proper degree of stress relaxation was measured by sectioning technique using strain gauge. Analysis model that is indispensable for the effective application of MSR method was established on the basis of test and measurement result.

The purpose of this study is to identify the principal factor controlling transverse residual stress at the weldment for joining unit hull blocks. In order to do it, the comprehensive FE analyses were carried out to evaluate the effect of distance between fillet and butt weldments, in-plane and out-of-plane restraint degree on the amount and distribution of transverse residual stress in way of the weldments between unit hull blocks. In accordance with FEA results, principal factor controlling the amount of transverse residual stress at the weldments was identified as in-plane restraint degree of butt weldment for unit blocks. The effect of other variables on the transverse residual stress was very small relatively. Based on the results, it can be concluded that the proper distance between fillet weldment for stiffener and butt weldment for joining unit blocks should be determined in consideration of in-plane restraint intensity of butt weldments.

Objectives : The purpose of this study was to examine the effect between job stress in jobholders and xerostomia. Methods : 250 jobholders living in Jecheon city were the subjects of this questionnaire. The questionnaire was made up of three contents and 37 items: general characteristic(13), job stress(14), degree & behavior of xerostomia(10). The data were analyzed by two-sample t-test, one-way ANOVA to examine the subjects general characteristics, job stress and degree of xerostomia and were analyzed by Chi-square test to examine the subjects general characteristics, job stress and behavior of xerostomia. Results : Only 215 jobholders were evaluated due to inadequate responses. The results were as follow. 1. As general characteristic of jobholder, male(83.7%) were more than women(16.3%), 30~39 year-old(47%) in age variable, university graduation(63.7%) in the last educational background variable, 2~3 million won(31.2%) in the month average income variable, 1~5 year(33.5%) in tour of duty variable, non-smoker(47.9%) in smoking variable were most. Married(58.6%) were more than unmarried(39.5%). Alcoholic(69.8%) were more than non-alcoholic(30.2%). 2. As classification of job stress, high strain group was 28.4%, active group was 26%, low strain group was 24.2%, passive group was 21.4%. 3. Analysis of effect between general characteristic and degree & behavior of xerostomia showed smoker were statistical significantly higher than non-smoker on 'dry eat', 'Am-sal', 'Night awake', 'Slip-liq'and 'Gumcandy'(p<0.05) and showed alcoholic were statistical significantly higher than non-alcoholic on 'Dry PM', 'Night awake, $H_2O$-bed'(p<0.05). 4. Analysis of effect between job stress and degree & behavior of xerostomia showed hight strain group were statistical significantly higher than low strain group on 'Dry PM', 'Dry-day', 'Am-sal', 'Eff-life'and 'Night awake'(p<0.05). Conclusions : As high strain group were higher than other groups on degree & behavior of xerostomia, stress would be factor that have an effect on xerostomia. Thus consider and management of stress is necessary for diagnosis and treatment of xerostomia.

Purpose: This is a descriptive research study that aims to identify factors affecting fatigue by examining the degree of emotional labor, job stress, and fatigue of 119 emergency medical technicians (119 EMTs). The correlation between emotional labor, job stress, and fatigue was also confirmed. Methods: A total of 139 EMTs working in the Daejeon area participated in this study. Data were collected from July 6-15, 2021. Results: When the number of dispatches was high and the job was dissatisfying, the degree of emotional labor was high. In addition, the shorter the work experience and the lower the job satisfaction are, the higher the job stress is. The degree of fatigue was significantly higher in female than male 119 EMTs, and when they had short work experience and were dissatisfied with their job, the degree of fatigue was higher. Moreover, there was a significant correlation between emotional labor, job stress, and fatigue of the 119 EMTs. Conclusion: To reduce emotional labor, job stress, and fatigue of 119 EMTs, appropriate interventions for each factor and institutional improvements are required.
