Sickness absence is one of the most important indicators for worker's health and occupational safety and health performance. Sickness absence is primarily depended upon sickness but psycho-social factors in workplace may moderate sickness absence. Even though worker is falling into illness, sickness absence can be prevented by job satisfaction. In Korea it is very difficult to find research output about the association of sickness absence with job satisfaction. This study is planned to investigate the effect of job satisfaction on sickness absence. The third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011 was used to analyze by logistic regression analysis. The result has shown that job satisfaction has statistically significant effect on sickness absence and simultaneously diminish the effect of symptoms experience on sickness absence. The effect of job satisfaction is greater in short term sickness absence than in long term sickness absence. This study has some limitation because of the cross sectional data of Korean Working Conditions Survey. In future, sophisticated statistical analysis may be done with modelling.

This study attempts to verify effects of CEO' supports, compensation and educational training and those of individual annual salaries and company's sales on promotion of knowledge management expected to contribute to enhancing construction industry's competitiveness, from the perspective of person-organization fit. For the analysis, a total of 368 effective questionnaires were used to conduct independent sample t-test, regression analysis and hierarchical moderated regression analysis. The findings show that individual annual salaries have a positive relationship with company's performance and company's sales also have positive relationships with both knowledge management activities and company performance, and CEO's supports, compensation and educational training are important factors that can improve knowledge management activities. In addition, the principle that the rich get richer and the poor get poorer is also operated in construction industry, as in other industries. Therefore, members in a company should conduct optimal strategies to enhance the knowledge management activities through selection and concentration, while governmental agencies require the establishment of IT system for it and supports for related cost and consulting of it.

Background: This study investigated the effects of positive psychological capital on the relationship between emotional labor and job satisfaction among dental hygienists. Methods: Data were collected from 296 dental hygienists working at clinical sites in Korea between July 25 and August 15, 2022. Participants were surveyed using structured questionnaires. Statistical analysis was performed using an independent t-test, ANOVA, descriptive statistics, and stepwise multiple regression analysis using SPSS/WIN 21.0. The mediating effect of positive psychological capital on the relationship between emotional labor and job satisfaction was tested using Baron and Kenny's 3-step hierarchical regression analysis. Results: Emotional labor was negatively correlated with positive psychological capital (r=-0.148, p=0.011) and job satisfaction (r=-0.214, p<0.001). Positive psychological capital had a positive correlation with job satisfaction (r=0.441, p<0.001). In addition, the positive psychological capital, had a partial mediating effect (z=-2.472, p=0.013) on the relationship between emotional labor and job satisfaction. Conclusion: Attitudes that reduce emotional labor, which adversely affects job satisfaction, and bolster positive psychological capital are needed.

There is no prior research on organizational commitment and supervision for social welfare public officials in charge of public-private cooperation in public welfare fields. Therefore we are designed to determine the impact of social welfare public officials' public-private cooperation awareness on organizational commitment to verify the moderating effect of supervision on the effect between public-private cooperation awareness and organizational commitment. The analysis data is 242 questionnaires collected from Incheon public health and welfare officials visiting towns, villages, and villages in 10 counties. Using the SPSS 22.0 program, descriptive statistics and relationships between variables were analyzed, regression analysis was performed to analyze the influence between variables, and hierarchical regression analysis was performed to verify supervision control. As a result of the study, it was confirmed that the perception of public-private cooperation affects organizational commitment, interacts with supervision satisfaction, and has a moderating effect. Based on this, in order to improve the organizational commitment of social welfare public officials during public-private cooperation work, specific measures were proposed for sharing awareness and understanding between the public and private sectors, establishing an official system, and establishing a supervision system.

It has gradually become important to estimate a forest stand volume utilizing LiDAR data. Recently, various statistical models including a linear regression model has been introduced to estimate a forest stand volume using LiDAR data. One of limitations of the current approaches is in that the accuracy of observed forest stand volume data, which is used as a response variable, is questionable unstable. To overcome this limitation, we consider a spatial structure for a forest stand volume. In this research, we propose a hierarchical model for applying a spatial structure to a forest stand volume. The proposed model is applied to the LiDAR data and the forest stand volume for Bonghwa, Gyeongsangbuk-do.

The purpose of this study is to examine how career decision-making self-efficacy and ego-resilience of college students after military service influence college life adjustment. For this purpose, the questionnaire was administered to 234 male college students who returned to the four-year university in Jeonbuk area. The collected data were analyzed by correlation analysis and hierarchical regression using SPSS 18.0. As a result of examining the correlation between each variables, the subscale adaptation of college life adjustment and university environment adaptation showed a positive correlation with the goal selection of career decision self-efficacy and optimistic attitude of ego-resilience. Future plan of career decision-making self-efficacy, optimistic attitude of ego-resilience and personal-emotional adaptation of college life adaptation showed a positive correlation between self-evaluation of career decision self-efficacy and self-resilience confidence. As a result of hierarchical regression analysis, it was found that ego-resilience had more influence on college life adjustment than career decision self-efficacy. The limitations of this study were discussed along with the significance of this study, which was revealed through data collection only for students who came back after military service.

Objectives: This study aimed to collect information that will help enhance the social networks and improve the quality of life among elderly people by observing the relationship between their social network and health-related quality of life (HRQoL) and by analyzing social network factors affecting HRQoL. Methods: This study was based on the 2008 Community Health Survey in Yeoncheon County. Three hundred elders were included in the study population. We compared the revised Lubben Social Network Scale (LSNS-R) score and Euro quality of life-5 dimensions health status index by demographic characteristics and chronic disease prevalence. We analyzed the data using multiple regression and tobit regression by setting the HRQoL as the dependent variable and social network and other characteristics as the independent variables. We analyzed social network factors by using factor analysis. Results: The LSNS-R score differed significantly according to age and existence of a spouse. According to the results from the hierarchical multiple regression analysis, the LSNS-R explained 0.10 of the variance and LSNS-R friends factor explained 0.10 of the variance. The tobit regression indicated that the contribution of the LSNS-R family size factor to the regression coefficient of the independent variable that affected the HRQoL was $B_T$=2.96, that of the LSNS-R family frequency factor was $B_T$=3.60, and that of LSNS-R friends factor was $B_T$=5.41. Conclusions: Social networks among elderly people had a significant effect on HRQoL and their networks of friends had a relatively higher effect than those of family members.
