Purpose: This study explores the impact of discrimination experience on stress levels among Seoul's public housing complex residents, emphasizing the moderating role of social capital. Research design, data and methodology: Utilizing the 2019 Seoul public housing (PH) panel data and an ordered logit model, the research categorizes residents based on personal and environmental factors, contrasting them across different local housing price levels. Results: We find that public housing residents' experience of discrimination has a significant impact on stress, and local housing prices are positively related to stress. Interestingly, stress due to discrimination is more pronounced in high-priced neighborhoods, which are associated with real estate inequality. Conversely, this impact is less pronounced in lower-priced neighborhoods. Importantly, social capital not only has a significant moderating effect on stress for all residents, but in high-priced neighborhoods, it also moderates the stress caused by experiences of discrimination for social housing residents. Conclusions: These findings highlight the need for policy interventions to strengthen social capital and address socioeconomic disparities in public housing, and are significant for analyzing the nuanced relationship between neighborhood, housing affordability, discrimination, and stress in urban communities for public housing residents, which is a socially problematic issue.

Objective We developed easily accessible imagery-based treatment program for patients with post-traumatic stress disorder (PTSD) related to workplace accidents and investigated the effects of the program on various PTSD related symptoms. Methods The program was based on an online platform and consisted of eight 15-min sessions that included script-guided imagery and supportive music. Thirty-five patients with workplace-related PTSD participated in this program 4 days per week for 4 weeks. Its effects were examined using self-report questionnaires before and after the take-home online treatment sessions. Results After completing the 4-week treatment program, patients showed significant improvements in depressed mood (t=3.642, p=0.001) based on the Patient Health Questionnaire-9 (PHQ-9), anxiety (t=3.198, p=0.003) based on the Generalized Anxiety Disorder seven-item (GAD-7) scale, and PTSD symptoms (t=5.363, p<0.001) based on the Posttraumatic Stress Disorder Check List (PCL). In particular, patients with adverse childhood experiences exhibited a greater degree of relief related to anxiety and PTSD symptoms than those without adverse childhood experiences. Conclusion The present results demonstrated that the relatively short online imagery-based treatment program developed for this study had beneficial effects for patients with workplace-related PTSD.

The moderators that relieve negative effects of emotional labor have been studied such as job characteristics and situational variables. But as reviewing these studies, they focused on the degree of emotional on certain condition, there's no distinction between that degree and moderating effects. So we should focus on the moderating variables as a organizational involvement. In this study, I hypnotized the mediating effect of job stress between emotional labor and organizational effectiveness. Then I explored moderating role of 'fairness perception of emotional labor' and 'problem-focused stress coping'. This study tested these relationships using data from 166 employees of domestic security service company. From this data, I found that emotional labor increases job stress and job stress fully mediates the relationship between individual attitude(job satisfaction, turnover intention). And one who perceives display rule fairer, feels less job stress than who is not. Lastly, one who copes more problem-focused when he/she experiences job stress, have less negative effect on turnover intention.

This paper aims to analytically investigate the effect of shear stress at the concrete-steel interface on the mechanical behavior of the circular steel tube-confined concrete (STCC) stub columns with active and passive confinement subjected to axial compression. Nonlinear 3D finite element models divided into the four groups, i.e. circumferential-grooved, talc-coated, lubricated, and normal groups, with active and passive confinement were developed. An innovative method was used to simulate the actively-confined specimens, and then, the results of the finite element models were compared with those of the experiments previously conducted by the authors. It was revealed that both the predicted peak compressive strength and stress-strain curves have good agreement with the corresponding values measured for the confined columns. Then, the mechanical properties of the active and passive specimens such as the concrete-steel interaction, longitudinal and hoop stresses of the steel tube, confining pressure applied to the concrete core, and compressive stress-strain curves were analyzed. Furthermore, a parametric study was performed to explore the effects of the concrete compressive strength, steel tube diameter-to-wall thickness ratio, and prestressing level on the compressive behavior of the STCC columns. The results indicate that reducing or removing the interfacial shear stress in the active and passive specimens leads to an increase in the hoop stress and confining pressure, while the longitudinal stress along the steel tube height experiences a decrease. Moreover, prestressing via the presented method is capable of improving the compressive behavior of STCC columns.

Purpose: The aim of this study was to identify the correlation among job stress, drinking, and smoking of local government staff. Methods: The participants of this study were 205 government staffs working in a local government office. The data were collected by self-report using questionnaires from March 2 to April 30, 2009. The data were analyzed using t-test, Chisquare test, ANOVA, and Man-Whitney test. Results: Physical stress was the highest in job stress components. Majority of the participants (96%) had drinking experiences more than once per month. 25.4% of respondents reported they drank more than 10 glasses each time. Smoking was habitual in 36.6% of the subjects and 28% of subjects had participation in a smoking cessation program. Respondents who reported high job stress had a longer history of smoking. Conclusions: Job stress was highly associated with drinking and smoking. Stress control programs and smoking and alcohol cessation/moderation programs could be beneficial for the health of government staffs.

This study aimed to identify parents' experiences of child-rearing on Saturday with no class as well as their perceptions and demands on the Five-day School Week system. The study participants were 640 parents with first to second grade children. The major results were as follows: First, parents were generally satisfied with the Five-day School Week System. Second, the Five-day School Week System increased fathers' role-sharing on the Saturday with no class. It was also related with some of the demographic variables and the Five-Week Workweek System of the father and the mother. Third, both the fathers and mothers had more parenting stress on Saturdays with no class than on Saturdays with classes. Their parenting stress on Saturdays with no class was related with some demographic variables and work flexibility.

In this paper, the thermal stress analysis of spent nuclear fuel disposal canister in a deep repository at 500m underground is done for the underground pressure variation. Since the nuclear fuel disposal usually emits much heat and radiation, its careful treatment is required. And so a long term safe repository at a deep bedrock is used. Under this situation, the canister experiences some mechanical external loads such as hydrostatic pressure of underground water, swelling pressure of bentonite buffer, and the thermal load due to the heat generation of spent nuclear fuel in the basket etc.. Hence, the canister should be designed to designed to withstand these loads. In this paper, the thermal stress analysis is done using the finite element analysis code, NISA.

A general treatment is to restore abfraction lesions with dental filler materials to reduce stress concentration. A material should be selected from various dental products based on long term experiences of dentist or personal preference concerning filler methods. A quantitative criterion is necessary to make an evaluation of the results as dentists decide treatment methods and dental materials relying on their clinical experiences. The purpose of this study is to find an optimal restoration method and material for noncarious cervical lesions using the finite element method. An objective function was defined to minimize the sum of tension or compression stress. Trial-and-error and approximation were used to find an optimal restoration method. An optimal solution was to fill TetricFlow inside the lesion and Z100 in the remaining region. The most desirable thickness ratio of the two filler materials was 0.125 with trial-and-error and it was similar to the results of approximation, 0.121 and 0.132.
