Purpose: This study examined the work-related musculoskeletal pain and quality of life of hospital workers. Methods: Self-reported questionnaires were sent to 350 hospital workers at Seoul and Gyeonggi-do, of which 341 were returned. The questionnaire had four items that covered the demographic information, areas of musculoskeletal problems, pain rating scale, and quality of life. The analysis was completed using descriptive statistic, and the differences between pain and demographic variables were identified using a chi-square test. The differences between the type of occupation and quality of life were analyzed by one-way analysis of variance and a Kruskal-Wallis test. Results: The 12-month prevalence of work-related musculoskeletal pain was 86.1% of physical therapists, 86.5% of occupational therapists, 77.1% of dental hygienists, and 75.8% of nurses. A significant difference in the general and work related variables was observed between the subject with a physical burden and type of occupation. The most affected pain sites of the physical therapist included low back, hand and wrist, shoulder, and neck. The occupational therapists included the hand and wrist, shoulder, neck, but the nurses and dental hygienists reported the shoulder, back, hand and wrist. A significant difference in the quality of life was noted between the subjects in physical therapists and dental hygienists and the subjects in the nurses and occupational therapists (p=0.00). Conclusion: These findings show that hospital workers appear to be high risk for work-related musculoskeletal pain, and the quality of life of physical therapists and nurses was higher than that of dental hygienists and occupational therapists.

The purpose of this study was to investigate the effects of clinical nurses' job stress, work-family conflicts, and burnout on their depression. Data was analyzed using descriptive statistics, t-test, one way ANOVA, Pearson's Correlation Coefficient and Stepwise multiple regression analysis. The results of this study shows that the job stress of the nurses was higher than average, the work-family conflicts was moderate, burnout was less than moderate, and depression was mild. The higher the job stress, the higher the conflict between workplace and family, the higher the burnout, and the higher the depression was. The main factor impacting upon the mental health of nurses was work-family conflicts followed by burnout. Therefore, it is necessary to develop a program that can prevent job stress and resolve burnout and support work-family conflicts to prevent depression of clinical nurses and to improve quality of life.

This study is a descriptive research study to confirm the mediating effect of work-life balance in the relationship between grit and job embeddedness of clinical nurses. Participants included 155 nurses from four hospitals located in D city. Data was collected from July 29 to August 19, 2022 using a self-report questionnaires. The collected data were analyzed by descriptive statistics, Pearson's correlation coefficient and Baron and Kenny's three-step hierarchical regression using the SPSS 22.0 program. In this study, it was found that there was a significant positive correlation between the nurse's grit, job embeddedness, and work-life balance, and it was confirmed that work-life balance partially mediated the relationship between grit and job embeddedness. Therefore, it is suggested that grit and work-life balance should be improved in order to improve the job embeddedness of nurses.

Purpose: The purpose of this study was to identify the effects of work stress, compassion fatigue and compassion satisfaction on burnout in clinical nurses. Methods: The sample consisted of 268 nurses from two general hospitals located in Seoul and Gyunggi province. Data were analyzed using frequencies, percentages, means and standard deviations, t-test, ANOVA, Scheff$\acute{e}$, Pearson Correlation and Hierarchial Multiple Regression. Results: Compassion fatigue had a significant positive effect on burnout, while Compassion satisfaction had a negative effect on burnout. The explained variance for burnout was 49% and compassion satisfaction was the most significant factor in burnout of nurses. Conclusion: The results indicate that the factors influencing nurses' burnout are work stress, compassion fatigue and compassion satisfaction. Therefore strategies to decrease work stress and compassion fatigue and to enhance compassion satisfaction for nurses are needed.

The study is to examine the mediating effect of psychological empowerment on the causal relationship between high-performance work system and organizational citizenship behavior. This study collected data from public organizations that are responsible for social welfare provision in Daegu, Gyeongsangbuk-Do, and Pusan in South Korea. This study employs confirmatory factor analysis in Amos 21 to find the discriminant validity of all constructs and regression analysis by Baron and Kenny (1986) to test that psychological empowerment is a mediator of the causal relationship between high-performance work system and organizational citizenship behavior. As the result of the analysis, psychological empowerment has a significant mediating effect on the relationship between high-performance work system and organizational citizenship behavior. The study suggests to the managers in social welfare organizations how they need to enhance organizational citizenship behavior through psychological empowerment themselves.

The objective of this paper is to estimate the PCE(Passenger Car Equivalents) of various vehicle types on expressway work zones. Headway samples of 5,359 vehicles were collected in 6 work zones in the Kyungbu Expressway between September and November of 1995. Average headways of 8 vehicle types based on the vehicle classification method of the Department of Construction and Transportation were calculated. A statistical test of effects of the types of the preceding vehicles were performed for the average headways between a vehicle type preceded by other vehicle types. The results show that the effects of the type of preceding vehicles are significant (exceeded 5% and 10% significance levels) and the PCEs of heavy vehicles on expressway work zones are higher than that of basic expressway section. Therefore, different adjustment factors should be applied for heavy vehicles in estimating saturation flow rates of expressway work zones. The study also derives an equation to determine PCEs of these vehicle types.

The purpose of this study is to Investigate color schemes, degree of its satisfaction, and color implication of office environment. This study is to find the proper current color schemes in offices today, as well as colors that will enhance efficiency and productivity in work for future uses. The study was progressed through visiting offices and survey The collected data were analyzed by using such descriptive statistics as percentage, frequency, mean, and t-test. The result of this study shows that most of offices applied the main color only for ceilings, walls, and floors; and, some of them applied supporting colors in addition to main colors. In general, workers are not satisfied by the color in their work environment. Therefore, careful planning and exploring color schemes of main colors and supporting colors in work environments can be suggested. Also, the study results of color implication in work environment indicates that there is a need to take a careful color planning, especially in relation to the type of work, sex, and the level of education of a worker.

The aims of this study are to evaluate the application on the stress-strain behavior of granite Soil using Lade's double work hardening constitutive model based on the theories of elasticity and plasticity. From two different sites of construction work, two disturbed and compacted weathered granite samples which are different in partical size and degree of weathering respectively were obtained. The specimen employed were sampled at Iksan and Pochon in order to predict the constitutive model. Using the computer program based on the regression analysis, 11 soil parameters for the model were determined from the simple tests such as an isotropic compression-expansion test and a series of drained conventional triaxial tests. In conclusion, it is shown that Lade's double work hardening model gives the good applicability for processing of stress-strain, work-hardening, work-softening and soil dilatancy. Therefore, this model in its present form is applicable to the compacted decomposed granite soil.
