The psychological work environments which facilitate technology innovations in organizations are divided into two dimensions of supportive work environments and challenging work environments. The confirmatory factor analysis confirmed the construct validity of two work environments. And simple and hierarchical regression analysis confirmed the significant effects of two work environments on motivations to the technology innovations. Therefore, Both of the challenging work environments(uncertainty of exta- organizational environments and tasks) and supportive work environments(managerial environments of intra-organizations) are the two important psychological work environments which facilitate technology innovations in organizations.

The psychological work environments which facilitate technology innovations in organizations are divided into two dimensions of supportive work environments and uncertain work environments. The measurement variables have significant reliability. And the confirmatory factor analysis confirm the construct validity of two dimensional work environments. Two work environments have the significant effects on motivations to the technology innovations. So, simple and hierarchical regression analyses confirm criterion-related validity. Therefore, Both of the uncertain work environments(uncertainty of external-organizational environments and tasks) and the two important work environments(supporting idea, resource supply, job autonomy) are the two important psychological work environments which indicate technology innovations in organizations. Measures for innovative psychological work environments are provided.

Background: Social status might be a determinant of occupational health inequalities. This study analyzed the effects of social status on both work environments and health outcomes. Methods: The study sample consisted of 27,598 wage employees aged 15 years and older from among the Korean Working Condition Survey participants in 2011. Work environments included atypical work, physical risks, ergonomic risks, work demands, work autonomy, social supports, and job rewards. Health outcomes comprised general health, health and safety at risk because of work, the World Health Organization-5 Well-being Index, work-related musculoskeletal disease, and work-related injury. Multivariable logistic-regression models were used to identify the associations between social status and work environments and health outcomes. Results: Employees in the demographically vulnerable group had lower occupational status compared with their counterparts. Low social status was largely related to adverse work environments. Especially, precarious employment and manual labor occupation were associated with both adverse work environments and poor health outcomes. Conclusion: Precarious and manual workers should take precedence in occupational health equity policies and interventions. Their cumulative vulnerability, which is connected to demographics, occupational status, adverse work environments, or poor health outcomes, can be improved through a multilevel approach such as labor market, organizations, and individual goals.

Stress is a primary health promotion issue in worksite research because psychological distress is closely related not only to workers　 health status but also to their job performance. This study identified the work environment and work condition factors affecting workers　 stress symptoms among the Korean manufacturing factory workers. A total of 7,818 factory workers employed in 1,562 manufacturing companies participated in the Korean nation-wide occupational health survey conducted by the Korean Occupational Safety and Health Agency in 2003. Participants were selected by the stratified proportional sampling process by standardized industry classification, company size, and locations. Trained interviewers visited the target companies and interviewed the factory workers randomly selected in each company. Work environments included physical work environments (temperature, noise, hazardous organic compounds, and so on) and psychological work environments (job demands, job control, and social support at work), and work conditions included daily working hour, rest time, and so on. Men were 71.5% and the mean age was 34.0 years old. The average working period in the present company was 6.9 years. The average stress score was 26.2 under the perfect score, 50, which means the moderate level of stress. Perceived stress had significant correlations with young age, poor physical work environment, high fatigue, bad perceived health status, and high job demands in Pearson's simple correlation analysis. Perceived health status and perceived fatigue explained 21% variance of stress symptoms and the work environment factor explained 4.8% of that; however, work condition did not have the sufficient effect. In particular, psychosocial work environment variables (job demand, job control, and social support at work) had a clear effect on stress symptoms rather than the physical work environments. Poor perceived health status, severe perceived fatigue, poor physical work environment, high job demands, low social support, heavy alcohol consumption and little exercise were significantly related to high stress symptoms in the Korean manufacturing workers.

The objective of this study is to investigate various jobs and foodservice environments, as well as work performances of school foodservice dietitians and nutrition teachers in accordance to the years of service in Daejeon and Chungnam provinces. A survey was conducted among school foodservice dietitians and nutrition teachers; a total of 415 from selected elementary, middle and high schools in the areas. In this study, we surveyed the participants and analyzed the current state of general characteristics, status of their job environments and foodservice environments by frequency, and the averages and differences in work performance with regard to 12 work parts and 57 works using one-way ANOVA and Duncan's multiple range test according to the years of service. Six parts among 12 work parts were significantly different in work performance according to the years of service. The 6 work parts were menu (nutrition) management, utensil recovery and management, sanitation management, foodservice administration & evaluation, dietary habit guide, and other works. The 11-15 years group ranked as the top on the total score and means of work performance. While the 16-years or more group, 6-10 years group, and under 5 years group followed consecutively. Correlation analysis between job or foodservice environments and work performances showed that work performances of school dietitians were mostly influenced by employment status, education level, and annual salary among the variables of job or foodservice environments. Other works, dietary habit guides and menu management were mostly influenced by variables of job and foodservice environments.

Purpose: This study aimed to compare work-related musculoskeletal symptoms, occupational stress and nursing work environments of nurses working in patient-sitter wards and general wards. Methods: The study surveyed 240 nurses with more than one year of experience working in both patient-sitter wards and general wards. The collected data then was analyzed by SPSS statistics version 22. Results: As for the musculoskeletal symptoms, the survey showed that 85.2% and 67.8% of the nurses had such symptoms respectively in patient-sitter wards and general wards. In terms of occupational stress, no significant difference was observed between the patient-sitter ward and the general ward (t=-0.23, p=.821). Lastly, the study showed that there is a significant difference in terms of work environment considering the scores recorded 2.65 and 2.55 points respectively in patient-sitter ward and general ward (t=2.53, p=.012). Conclusion: Follow-up research should look at ways to lower the rate of experiencing work-related musculoskeletal symptoms; analyze work performances and establish work standards to lower occupational stress; and devise measures to improve the work environment for the nurses working in patient-sitter wards.

In ubiquitous computing, shared environments adjust themselves so that all users in the environments are satisfied as possible. Inevitably, some of users sacrifice their satisfactions while the shared environments maximize the sum of all users' satisfactions. In our previous work, we have proposed social welfare functions to avoid a situation which some users in the system face the worst setting of environments. In this work, we consider a more direct approach which is a preference based clustering to handle this issue. In this approach, first, we categorize all users into several subgroups in which users have similar tastes to environmental parameters based on their preference information. Second, we assign the subgroups into different time or space of the shared environments. Finally, each shared environments can be adjusted to maximize satisfactions of each subgroup and consequently the optimal of overall system can be achieved. We demonstrate the effectiveness of our approach with a numerical analysis.

Work environments have been changed with the advent of new technologies, such as computer technology. The newer technologies, the more changes in our work conditions. However, human cognitive limits can't keep up with the change of work environments. Mental workload has been an important factors in designing modem work environments such as human-computer interaction. Designing man-machine systems requires knowledge and evaluation of the human cognitive processes which control information flow workload. Futhermore, under an urgent situation, human operator may suffer the work stress, work error, and resultant deleterious work performance. To describe the work performance in the urgent work situations, with time stress and dynamic event occurence, a new concept of information density was introduced. For a series of experiments performed for this study, three independent variables(information amount system processing time, information density) were evaluated using such dependent variables as reaction time, number of error, and number of failure. The results of statistical anlysiss indicate that the amount of information effected on all of five dependent measure. Number of failure and number of secondary task score were effected by both amount of information and operational speed of system, but reaction time of secondary task were effected by both amount of information and information density.

The purpose of this study was to determine the correlation between the COVID-19 related post-traumatic stress, nursing work environments, and the resilience among nurses in Tertiary General Hospitals. Data were collected from 155 nurses who directly cared for COVID-19 patients and were working at the K University D Hospital in D Metropolitan City using an online survey. The SPSS 28.0 program was used for data analysis. Based on the results of the survey, post-traumatic stress showed a significant negative correlation with the nursing work environments(r=-.17, p<.001), and the nursing work environments showed a significant positive correlation with the resilience of nurses(r=.20, p<.001). Through the results of this study, it is necessary to improve the nursing work environments for managing post-traumatic stress, to build an active support system by securing manpower from the government, and to develop and apply intervention programs for improving the resilience of nurses in the COVID-19 situation.

Purpose: The aim of this study was to explore the association between psychosocial work environments and depressive symptoms among Korean registered nurses. Methods: The study population of 331 registered nurses was derived from the 2014 Korean Working Condition Survey (KWCS). Depressive symptom was assessed using the WHO-5 wellbeing index. Results: The thirty-five percentage of Korean registered nurses reported the risk for depressive symptom. Korean nurses with higher 'work-family conflict' were more likely at the risk of depression almost 1.83 (95% CI 1.04~3.20) times than their counterpart. Higher 'possibilities for development' were more likely decrease almost 60% of the risk of depressive symptom. Conclusion: Work-family conflict and possibility of development were associated with depressive symptom among Korean registered nurses. We suggest future researches identifying strategies for decreasing work-family conflict and its negative effects.
