The study aims were to verify the influences of job environment factors and work attitude on turnover intention of school foodservice employees, and then to verify the mediating effect of organization commitment between six areas of worklife and turnover intention so that organizations can intervene to reduce the turnover intentions of employees. The subjects were 205 employees who were working in the school foodservice field. The job environment factors were measured by six areas of worklife (workload, control, reward, fairness, community, value) and the organizational commitment was measured by two types of commitments (affective, continuance). The results were as follows. First, workload, reward, community and value of six areas of worklife reduced affective commitment, control and fairness increased continuance commitment, and affective commitment reduced turnover intention. Second, only reward and community showed direct effect on turnover intention, but all six areas of worklife had a statistically significant indirect effect on turnover intention through affective commitment. These results showed that job environment factors had both direct and indirect effect on employees' behavior through employees' affection. These findings imply that organizations can control employees' turnover intention by providing education or social support to maintain their affective commitment even when organizations cannot change job environment.

Virtual reality is a technology that enables users to implement environments that are separate from the real world, and immersion is an important factor in implementing separate environments. However, a variety of studies have been conducted to solve this problem as the lack of awareness of the surrounding environment can lead to an unstable virtual reality game environment. Most studies are focused on solving problems through visualization. On the other hand, because visualizations are generally information that is not relevant to the space of virtual reality, research is needed on the effect of the degree of immersion in virtual reality to which they are applied. The guidelines are necessary because there are differences in individual tendencies and the factors that influence the immersion. In order to solve these two problems, we are going to conduct experiments on two systems: a survey based on the immersion tendency and a visualized communication of information about the surrounding environment. Through these results, we will measure the immersion of individuals and identify the impact of visualizations on virtual reality games by dividing them by their propensity to do so to present guidelines on the creation of virtual reality game environments based on the individual's tendency to engage in immersion.

This study found out a process of effects of professional identity recognized by social workers on their job satisfaction and organizational commitment, and verified a mediated effect caused by working environment through the process. A survey for data collection was conducted among 205 employees of social welfare facilities located in Gyeonggi Province. Collected data was analyzed by using structural equation modeling. The data analysis showed that first, professional identity has an extremely meaningful positive effect on job satisfaction. Second, professional identity has a meaningful positive effect on organizational commitment. Third, working environment has a partial mediated effect on relationships between professional identity and job satisfaction, between professional identity and organizational commitment. These results proved that the enhancement of job satisfaction and organizational commitment of social workers is based on enhancing professional identity, and organizational commitment can be enhanced by the working environment. Based on the results, this study discussed practical plans for enhancing job satisfaction and organizational commitment of social workers.

The objective of this study was to examine the possibility of utilizing the immersion stereoscopic image with a curved-screen-display as a tool for evaluating the landscape. The curved-screen-display ensures the continuity of the image and can be simultaneously evaluated by many people. Fifty-meter-wide Gangnamdaero Boulevard in Seoul was selected for this study, and the simulation was done using computer graphics. With the computer simulation, a questionnaire on landscape preferences was conducted according to different visual environments (immersion, non-immersion) and different projection types(stereoscopic or plane image). In the results of this study, the landscape preference was largely dependent on the immersion environment. Using the immersion-type simulation, the observer can easily evaluate the preference with higher judgment power. The stereoscope or plane projection type does not have any significant result in terms of its judgment power. This result implies that it is very important to strengthen the sense of immersion by expanding the screen into an angled view in which the observer can become immersed while making and projecting the simulation to evaluate the landscape. As a landscape evaluation tool for examining the efficiency and usefulness of immersion simulation, this study has limitations in that it controls many factors in street landscape that adversely affect judgment. Accordingly, a detailed comparison and verification of the stereoscopic image in various environments, including street width and building height ratio, must be conducted.

This study analyzes the effects of the KTX driver's person-environment(job, organization, Coworker) fit on job satisfaction, organizational commitment and turnover intention. It, additionally, examines the mediating effect of job satisfaction and organizational commitment between person-environment fit and turnover intention. Consequence of the analysis indicates that person-environment fit has mostly meaningful influences on job satisfaction, organizational commitment and turnover intention. But person-job fit makes a meaningless impact on job satisfaction, and person-coworker fit also makes a meaningless impact on job satisfaction and turnover intention. The mediating effect of job satisfaction and organizational commitment is mostly effective, but the mediating effect of job satisfaction does not affect the relation between person-organization fit and turnover intention. In conclusion, this study implies that, in order to grasp KTX driver's turnover intention and to protect actual turnover, it is important to enhance job satisfaction and organizational commitment as well as to improve overall person-environment fit.

The purpose of this study is to investigate the mediating effect of psychological empowerment (PE) in the relationship between nursing work environment (NWE) and job involvement (JI) of nurses in operating rooms of small- and medium- hospitals. Subjects were 150 nurses in operating rooms of 24 small- and medium- hospitals nationwide, and data were collected from July to September 2018 using a structured questionnaire. Data were analyzed by t-test, ANOVA, Pearson's correlation coefficients and multiple regression. As a result of the study, JI was positively correlated with NWE or PE, PE was positively correlated with NWE. PE was found to partially mediate the effect of NWE on JI. In order to help nurses in small- and medium-sized hospital operating rooms to positively recognize the NWE and immerse themselves in the job, it is necessary to develop convergence program to increase PE.
