The effects of job stress factors on psychological job stress and job satisfaction levels of school dietitians were evaluated. Questionnaires were distributed to 163 elementary school foodservice dietitians in the Seoul and Incheon area. Statistical data analysis was completed using the SPSS program. The highest stress factor was the importance of the job followed by role ambiguity, autonomy and identity, communication and participation. When dealing with job stress, the subjects showed improved and positive behaviors when communicating and participating with each other. The analysis of the relationships between job stress factors and job satisfaction revealed that the importance of the job had a negative effect on jog satisfaction. while role conflict and overload, personal relationships, and experience accumulation had positive effects. Ample occupational experience and background had highly positive effects on school dietitians' job satisfaction level whereas negative results were shown concerning circulated appointments(p<0.01). Based on these results, we suggest that role conflict and overload should be reduced in order to lower job stress levels and enhance job satisfaction levels.

Objectives: This study aimed to analyze research literature, created over the past 10 years, on occupational stress among domestic dental hygienists and identify the major factors affecting occupational stress. Methods: Of the 192 articles found through literature searches, 26 were selected for the analysis after reviewing titles, abstracts, and full texts. General characteristics of each study, measurement tools employed, and data related to pertinent factors were systematically analyzed. Results: Seven instruments were utilized to measure job stress. Among the variables exhibiting positive correlation with occupational stress, turnover intention was the most prevalent, while variables showing negative correlation were predominantly associated with job satisfaction. Factors influencing occupational stress included emotional labor, workload, organizational social capital, and experiencing verbal abuse. Conclusions: With regard to the most influential factors, "emotional labor" and "turnover intention" had the greatest impacts on job stress and occupational stress, respectively. Based on the findings of this study, follow-up research needs to be conducted to suggest ways to prevent, manage, and reduce occupational stress among dental hygienists

Fashion stress is a pertinent aspect of modern consumer culture that has been underexplored in academic research. This study developed a conceptual framework of fashion stress and a multidimensional scale to measure consumers' fashion stress. The qualitative study included literature reviews on consumption stress, shopping stress, and consumer behavior, as well as focus group interviews to gain insight into various dimensions of fashion stress. NVivo 12.0 was used to analyze the qualitative data and identify core categories following the grounded theory methodology. The quantitative study involved a preliminary and a primary surveys to verify the validity and reliability of the fashion stress scale. A total of 220 questionnaires were used for data analysis. The results show that fashion stress consists of eight factors: care, shopping, fit, brand, financial, closet, style, and disposal. Choice difficulty plays a significant role in all factors of fashion stress. Moreover, shopping stress had a negative impact on impulse buying, while other factors such as fit, brand, closet, and disposal stress had a positive impact on impulse buying. Thus, fashion stress is a potential antecedent of impulsive consumer behavior. The results also confirm the validity and reliability of the scale. The fashion stress scale developed in this study offers researchers a valuable tool for assessing and understanding consumer experiences.

Objective: The purpose of this study was to investigate the job stress factors of mobile communication network construction workers using survey based on 'Job stress factors evaluation tool for Koreans' that was developed by KOSHA in 2003. Background: Due to the rapid growth of penetration rate of smartphone, the necessity of LTE service changing from 3G network was brought up. The demand of LTE network construction in a short period of time leads to the aggravation of the job stress of mobile communication network construction workers. Method: Two hundred and fifty workers who were in the mobile communication network industry participated in this study, and among them 206 responses were analyzed for this study due to the unreliability and insincerity of responses. The eight job stress factors which are physical environment, job demand, job autonomy, relation conflict, job instability, organizational system, inadequate compensation, workplace culture were analyzed. Results: The job stress factors of mobile communication network construction workers were compared to those of other industry workers, and other work related characteristics were analyzed. The results showed that the stress level of a physical environment and job requirement were relatively higher than those of manufacturing industry workers, meaning that mobile communication network construction workers have rough working conditions and increased amount of work due to the demand of LTE network construction. The stress level of physical environment for outdoor job workers was relatively higher than that of indoor job workers. With the analytical result for level of job satisfaction, significant difference was observed (p <0.05) with every factor, and the job stress was found the highest with those not satisfied with every factor Conclusion: From the results of this study, the work loss due to the job stress could be prevented, and accurate stress factors could be removed at the workplace. Application: The results of this study may not represent the whole mobile network construction workers, the effort for job stress management is needed to improve the work efficiency and the workers' quality of life.

Job stress factors are factors that induce biological, psychological, and behavioral responses in individuals when they encounter mental and physical stimuli in the workplace. According to occupational safety and health standards, employers are responsible for the health consequences of job stress when workers engage in activities that result in high levels of physical fatigue and mental stress. Such activities include long working hours, shift work (including night shifts), driving vehicles, and operating precision machinery. Therefore, precautionary measures should be implemented. Following the COVID-19 epidemic, the logistics industry in Korea has experienced rapid growth owing to the shift from offline to online platforms facilitated by advanced digital infrastructure. Consequently, this study conducted a survey to analyze job stress factors among delivery workers. The survey utilized a Korean job stress factor assessment tool comprising 43 items and analyzed job stress factors considering the work characteristics of the courier business field obtained from responses provided by 421 courier workers nationwide. The survey analysis revealed that the physical environment, job demands, and job autonomy exhibited higher stress indices among Korean workers. Furthermore, the younger the age, the higher the stress on job demands, whereas the higher the age, the higher the stress on relationship conflict, job instability, and workplace culture. In addition, daytime delivery work was associated with higher stress levels in job demands and job instability compared with nighttime delivery work. These findings can serve as foundational data for reducing and preventing job stress among courier workers, whose workload has increased owing to the growth of the logistics industry.

Accelerated life tests (ALTs) are frequently used in manufacturing industries to evaluate the reliability of products within a reasonable amount of time and cost. Test units are subjected to elevated stresses which yield quick failures. Most of the previous works on designing ALT plans are focused on tests that involve a single stress. Many times more than one stress factor influence the product's functioning. This paper deals with the design of optimum modified ramp-stress ALT plan for Burr type XII distribution with Type-I censoring under two stress factors, viz., voltage and switching rate each at two levels- low and high. It is assumed that usage time to failure is power law function of switching rate, and voltage increases linearly with time according to modified ramp-stress scheme. The cumulative exposure model is used to incorporate the effect of changing stresses. The optimum plan is devised using D-optimality criterion wherein the ${\log}_{10}$ of the determinant of Fisher information matrix is maximized. The method developed has been explained using a numerical example and sensitivity carried out.

Stress intensity factors for the bimaterial interface cracks are determined by the boundary element method employing the multiregion technique along with the double-point concept. For this purpose, the formulas relating the stress intensity factors to the crack surface displacements, which are applicable to both the homogeneous and the bimaterial systems, are derived and the accuracy of the results is discussed using the preexisting analytic solutions. Besides, the stress intensity factors for the edge-cracked bimaterial plates are computed with various crack lengths and shear modulus ratios under the biaxial and the uniaxial loadings, respectively, to demonstrate the dependence of stress intensity factors on the loading conditions and the material properties.
