The purpose of this study was to provide the evidence necessary to establish job stress management strategies to improve office workers conditions by looking at the impact on job stress factors depending on the nature of the organization. The stress related variables (job stress and psychological well-being) and organizational effectiveness variables (job satisfaction, job engagement, intention to leave, and presentieesm) was included. A total of 154 questionnaires were distributed from 26th June to 1 August 2014 and 150 people were analyzed. The results indicated that a lack of reward was negatively correlated with job satisfaction and job engagement, and positively correlated with the intention to leave (p<0.05) in a large-sized company model. Moreover, in a medium-sized company model, organizational injustice was statistically significant with job satisfaction and job engagement. Organizational injustice, lack of reward, and occupational climate was positively correlated with the intention to leave (p<0.05). This study has its significance in that it looked at the job stress as a predictive variable to explain the organizational effectiveness and highlights the need to establish a stress management strategy depending on the nature of the company.

The purpose of this study is to understand attributes, stress and burnout related to job environment of healthcare facilities workers for the aged, care-givers, analyze the effect of these factors on job satisfaction, and improve their organizational task to help advance the quality of life and the healthcare facilities for the aged. A survey was made on 129 care-givers working in the healthcare facilities for the aged(care facilities, in-home facilities for the aged) located in Jeonbuk Gunsan area. This study showed that sub-factors of care-givers' job environment such as human environment, compensation system and job expertise have a significant effect on the job burnout, stress and satisfaction. This means that a well-organized compensation system, which is proportionate to the job expertise and ability for human environment, and achievement of innovative thinking, will make a positive relationship, reduce the job burnout and stress, and improve the job satisfaction at the same time. Compared to the rapid increase of old aged patients for long-term care and care-givers' real role and job in the facilities, the job specialization has to be guaranteed to improve job environment of care-givers as various beneficial workers for welfare - professional workers - and the compensation system needs to be properly systematized according to their job capacity. Consequently, the production and participation of professionals with high self-esteem may raise organizational commitment through the maximization of job satisfaction by the participation and devotion to the organization of more professionals by removing factors, which can reduce the frequent job burn-out and stress of care-givers.

This study surveyed 230 firefighters working in Dae Gu City and Kyung Sang Buk Do in order to analyze the influence of social support and empowerment on occupational stress and its sub-categories. The study results show that occupational stress is reduced for firefighters when there is more social support and empowerment. For subcategory variables of occupational stress, occupational autonomy stress was influenced only by empowerment. Stress related to lack of compensation and stress from the organization's culture were influenced the most greatly by social support. The weekly fre quency of emergency mobilization and years of working were also found to influence occupational stress and its subcategory variables. The group difference analysis revealed that the fire department had a significantly higher occupational stress than the first-aid department, and 4 to 7 weekly emergency mobilizations corresponded to significantly higher occupational stress than 8 or more weekly emergency mobilizations. Based on the study results, stress management programs focused on increasing social support and empowerment for firefighters are suggested.

This study aims to investigate the impact of job stress on the job satisfaction and life satisfaction of local government officials who participated in the reading academy from January 2023 to March 2023. The research involved collecting 300 questionnaires and conducting multiple regression analysis to analyze the obtained data. The results of the study are presented below. Impact of Job Stress on Job Satisfaction: The analysis revealed that among the sub-factors of job stress, inappropriate compensation significantly increases job stress among local government officials in the reading academy. Moreover, the study found that turnover intention was particularly high when compensation was not recognized as appropriate, indicating it as the most significant source of job stress. Impact of Job Stress on Life Satisfaction: The findings demonstrate that several factors negatively influence job stress, leading to reduced life satisfaction among local government officials in the reading academy. These factors include undesirable changes in working conditions or situations, anxiety about reorganization, inconsistent work orders, gender discrimination, and an authoritative organizational atmosphere. Effect of Job Satisfaction on Life Satisfaction: The analysis of the relationship between job satisfaction and life satisfaction indicated that turnover intention and remuneration level in job satisfaction positively influenced emotional satisfaction. Conversely, the job itself and interpersonal relationships had a significant negative effect on emotional satisfaction. Furthermore, the job itself and the level of remuneration in job satisfaction showed a significant positive effect on physical satisfaction. Similarly, the job itself and the level of remuneration in job satisfaction positively affected social satisfaction, while the intention to change jobs had a significant negative impact.

본 논문에서는 최근 서버에 적용되고 있는 180~305 Vac의 높은 입력에 대한 종속 벅 부스트 형태의 역률 보상 회로를 제안한다. 제안된 컨버터는 277 Vac인 공칭 입력 전압에서 기존 부스트 역률 보상 회로와 동일하게 동작하며, 277 Vac 이상의 입력에서는 추가된 벅 스위치의 간단한 피드-포워드 제어를 통해 부스트 단의 평균 입력 전압을 낮추는 방법을 사용한다. 따라서, 277 Vac 이상의 높은 입력 전압에서도 기존 보다 낮은 출력 전압으로 컨버터가 동작하기 때문에, 기존의 부스트 컨버터에 비해 출력 콘덴서의 크기와 부스트 스위치, 다이오드의 전압 스트레스를 감소시킬 수 있다. 이를 통해 공칭 입력 전압에서 부스트 스위치의 스위칭 손실을 감소시킬 수 있고 높은 전력 밀도를 가질 수 있다. 본 논문에서는 제안된 컨버터의 분석과 함께, 유효성 확인을 위해 입력 180~305 Vac, 출력 400 V, 750 W 급 컨버터를 제작하였으며 실험을 통해 얻은 결과를 제시하였다.

The main purpose of this study was to examine the relationship among hoteliers' emotional labor like surface acting (SA) and deep acting (DA), job stress such as physical stress (PS) and mental stress (MS), and extra-role behavior (EB). Using data from 264 surveys collected from five-star hotels' employees, the author empirically tested the research model. Main results on applying structural equation analysis are as follows. (1) SA had positive impacts on both PS and JS while DA was negatively significant on only MS. (2) ER was influenced by DA while there was no significance on SA. (3) MS was negatively related to ER, and PS was also significantly effective; however, the estimate of PS indicated a positive correlation unlike theoretical prediction. In conclusion, a discussion about the interesting phenomenon was held based on self-rewarding acts.

Occupational Stress is defined the stress which occurs in the workplace or organization. In Korean workers, the rate of occupational stress was 87.8% which was the highest level among OECD countries(average 80.0%). The purpose of this study was to examine the empirical verification of the Korean Occupational Stress Scale(KOSS) in physical therapists. For this purpose, the subject of this study was set up physical therapists who were working at Gyeonggi province and collected from 388 persons by using purposive sampling. The collected data was conducted explanatory factor analysis and confirmatory factor analysis in order to ascertain factor structure and practical verification of KOSS. Major results were as following: first, the reliability of KOSS was 0.83, and it means that a measure of internal consistency is high. Second, the KOSS result of physical therapists was composed 7 subscales(job demand, insufficient job control, job insecurity, interpersonal conflict, occupational system and lack of reward, organizational climate) and that is more appropriate measurement scale than the original one by using explanatory/confirmatory factor analysis. This study could be contributed as a tool for evaluation and outcome of the basic information of related occupational stress in physical therapists.

This paper studied the stress of Metropolitan Transit driving crews. Stress to such workers can not only lead to fatalities and infrastructure damage but also enormous loss of competitiveness. The study was carried out to search for ways of alleviating stress of driving crews. In order to reduce the various factors that exacerbate job stress of driving crews of Metropolitan Transit, it is first necessary to expand training in order to enhance their expertise, and improve facilities to protect driving crews in the event of accidents. Second, psychological compensation or organization's systems may cause job stress. It may therefore be possible to solve fundamental problems through typical organization level approach such as leadership training programs. Third, job stress may be reduced through proper life habits such as personal regular exercise. Fourth, we need to improve driving crews' working conditions and adjust working hours by avoiding excessive performance competition and an unfair evaluation system, by understanding their mental states, and by setting up systems such as a comprehensive health improvement and management program at the organization level.
