The purpose of this study was to investigate the actual conditions related to the working environment of radiological technologist who is working in small or medium-sized hospitals or clinics. The results of this study were intended to improve the working environment of radiological technologist and care for patients. For data collection, a structured questionnaire was used as a research tool, and 838 women (52.4%) were used as a general characteristic of 1,598 people subject to this questionnaire. The annual salary of radiological technologists with less than one year experience was 33.76 million won, and the average annual salary of radiological technologists with more than 10 years of experience was 41.33 million won. It showed an increased of 1.84% per year. Among 1,540 radiological technologists, 879 workers were paid holiday work allowances, 340 workers did not, and 321 holiday workers work during the week. In addition, a total of 817 workers received overtime payment, of which 112 received overtime wage on a monthly basis regardless of the overtime hours. In addition, a total of 348 radiological technologists were not paid overtime wage, and 138 workers were included in the basis salary. There were no union in 85% of the them. According to the results of this study, the wages and working environment of radiological technologists in small or medium-sized hospitals or clinics were not appropriate. Therefore, the efforts of the radiological association and its members are necessary to provide a better working environment for radiological technologists. In addition, it is expected that this study will be used as basic data for the association's policy to improve the working environment of members who work in poor conditions.

Today, when innovation and creativity become increasingly important, management of human resources is a key factor for corporate performance and competitive advantage. Corporate are implementing and introducing various types of support methods for members to achieve goals and improve organizational performance. Organizational culture and organizational trust affect the cognitive and emotional state of members. Furthermore, it can bring about changes in organizational performance such as job stress and job satisfaction. From an institutional point of view, work-life balance is also a major factor affecting organizational performance. The imbalance between work and life leads to a decline in organizational performance, such as decreased morale and dissatisfaction with work. In relation to work-life balance, the low birth rate problem intensified and the importance began to emerge. Therefore, the government has implemented various policy support for workers' work-life balance, and the "52-hour workweek" is a representative example. This study analyzed the effect of organizational culture applying the competitive value model on workers' job stress. In addition, the mediating effects of overtime work per week and organizational trust were analyzed. Job stress corresponds to a prerequisite stage that affects job commitment, job satisfaction, and turnover intention. However, research measuring job stress by organizational performance is insufficient. In addition, there are few studies analyzing the relationship between overtime and organizational performance. Considering this, it is necessary to understand the influence relationship. The results of the study are as follows. First, a hierarchical culture increases the job stress of workers. On the other hand, innovation-oriented, relationship-oriented, and competition-oriented corporate culture reduce job stress. Second, a hierarchical culture has reduced trust in the organization, and other organizational cultures have increased trust in the organization. Third, relationship-oriented and competition-oriented organizational culture reduced overtime. Innovation-oriented, hierarchical-oriented culture increased overtime Fourth, organizational trust and overtime have the effect of mediating organizational culture and job stress. Based on these analysis results, this study presented academic and political implications.

This paper addresses a problem of machining route selection in multi-stage process with machine group. This problem is considered the subcontracting and the production in-house such as regular and overtime work. the proposed model is formulated as a 0-1 integer programming constraining the avaliable time of each machine for planning period and total overtimes. The objective of the model is to minimize the sum of processing cost, overtime cost, and subcontracting cost. To solve this model, a genetic algorithm(GA) approach is developed. The effectiveness of the proposed GA approach is evaluated through comparisons with the optimal solution obtained from the branch and bound. In results, the same optimal solution is obtained from two methods at small size problem, and the consistent solution is provided by the GA approach at large size problem. The advantage of the GA approach is the flexibility into decision-making process because of providing multiple machining routes.

Many enterprises are performing the production planning computerization for survival in unlimited competing period. But it is very difficult to directly apply many production planning softwares to the domain-specific areas of many small enterprises because one enterprise is different from the others with respect to product type, production process, and order fulfillment method. Practically most small enterprises depend on experienced production managers in production planning, so then many problems such as overtime work and cost have been appeared. The purpose of this study is to develop production planning module for order-made production system in order to reduce overtime works and surplus costs. We developed production planning module with RDBMS, which is fit for small manufacturing company. Developing this software, we use Visual Basic 5.0 to provide GUI environment for the production planning module and Microsoft Access 97 is used to construct Database. This production planning module is applied to enhancement of productivity in M manufacturing company located in Asan.

The policy proposal by the current Korean government that proposes flexible overtime rules is causing social controversy. This study has explored the 612 experts' opinions on the occupational safety and health impacts of the policy using an online self-report survey. They expected short-term overwork (87.25%), overwork inequality (86.44%), irregular working hours (84.31%), chronic overwork (84.15%), long working hours (83.66%), and unpredictability of working hours (81.86%) as a result of the policy change. They also responded that the policy change would increase industrial accident deaths (87.25%), mental illnesses (87.09%), deaths due to overwork or cardiovascular diseases (83.84%), and accidents (83.33%). They disagreed that the government's flexibilization policy, while agreeing that the necessity of policies on regulating night work (94.77%), guaranteeing wages to eliminate overtime (90.36%), establishing working time regulations for the bogus self-employed (82.84%), and applying the 52-hour workweek system to all workplaces (76.47%). These expert opinions are consistent with previous research on the health effects of working hours.

Purpose: The purpose of this study was to identify Relationship between job stress and job satisfaction of dental hygienists Methods: The subjects of this study were to 173 dental hygienists who work in dental diseases and clinics in Busan, Ulsan, and Gyeongnam, and through the Internet link using web questionnaire from August 1 to October 30, 2023. Distributed and collected. The collected data were analyzed using an IBM SPSS ver. 26. Results: As for general characteristics, job stress was high in the 40s age group, work experience was high in the 1-4 year group, and job satisfaction was high in the 4-7 year or more group. As factors affecting job satisfaction, it was found that the lower the Self- determination of duties , the lower the Job insecurity, and the lower the Inadequate compensation, the higher the job satisfaction. Conclusions: From the above results, in order to increase the job satisfaction of dental hygienists, it is necessary to ensure stable employment and at the same time allow them to focus on tasks specific to dental hygiene, as job satisfaction decreases if a lot of chores unrelated to dental hygiene work are performed, and Self- determination of duties and an appropriate compensation system must be established. If an excessive workload is given or there is frequent overtime work, compensation should be made commensurate with experience or ability, and in the case of frequent overtime work, appropriate compensation should be provided through allowances or incentives.

There are several types of shift work in Korea: rotating shift, 24-hour shift, day-night shift, fixed night work, and.so on. As a result of analyzing the 8th Korea National Health and Nutrition Examination Survey and the 6th Korean Working Condition Survey, Korean shift workers accounted for 11.6%-13.9% of wage workers. Weekly working hours of shift workers were 57.69 ± 1.73 (24-hours shift) and 49.97 ± 0.67 (fixed night shift), which were significantly longer than day workers. To prevent health consequences of night work, many countries regulate the working hours of night work not to exceed 7-9 hours a day. However, Korea does not regulate working hours for night work, and some occupations may work more hours than the prescribed overtime hours. To prevent health consequences and reduce working hours for Korean night shift workers, it is necessary to regulate the working hours of night shift workers by law.

Purpose: This study was conducted to understand the effects of daily hassle stress on the psycho-social health of male workers in manufacturing industry. Methods: Daily hassle stress and psycho-social health in manufacturing industry workers were estimated by using the Daily Hassles Scale for Korea Workers (DHS-KW) and general health questionnaire (GHQ), respectively. Results: The subjects were 553 male workers who had never been occupationally exposed to hazardous chemicals, were mean age 39.6 years and mean work duration was 15.66 years. DHS-KW total mean score had significantly higher in young ages (twenties and thirties ages), office workers, managers and daytime workers than other groups. GHQ total mean scores were significantly higher in un-married, daytime and overtime workers than others. DHS-KW and GHQ score correlated that they were negative correlation with age and working years, but was positive correlation with working hours and overtime work. The significant correlation between DHS-KW and GHQ were observed almost variables of DHS-KW and GHQ except a domestic and daily problem in DHS-KW variables. Domestic and daily problems were only significantly correlated with anxiety and insomnia of GHQ variables. Conclusion: This study indicated that physical health was associated with work condition and psychsocial health was mainly associated with domestic and daily problems of DHS-KW variables. Thus, the study on Daily Hassles stress and related with work stress should be further investigated for the comprehensive health program including stress management and coping behavior.
