This study was conducted in order to analyze job stress factors of radiotechnologists in order to inprove the work efficiency and to organize system management plans. For data collection, total 261 radiotechnologists, who work in Busan, took part in structured questionnaire survey. The collected data were analyzed by using SPSS/PC+ Win 13 version. For verification of the differences among groups, one-way ANOVA was executed. For analyzing efficiency of system, which is affected by job stress, multiple regression analysis was taken. First, work stress classified by age group was found as the biggest stress factor among radiotechnologists in their 30s. Among radiotechnologists in their 20s, 40s and 50s, the biggest stress factor was communication problems. In terms of, job stress classified by division, no statistical difference was observed among groups. Second, as the result of system efficiency analysis, high values were found in organizational immersion and job satisfaction among radiotechnologists in their 20s and oncology division has the highest values in concentrating the system and job satisfaction. For this result, statistically significant differences were observed among groups. Third, in terms of the sub-factors of work stress, communication problem was found as the variable that exerted statistically significant impact to organizational effectiveness. However, no statistically significant differences were observed inadministrative and personal problems. Job stress decreases as communication within the organizations or communication with other divisions becomes more successful. In other words, system efficiency can be enhanced by decreasing conflicts within organization through successful communication.

3D histology is a imaging system for the 3D structural information of cells or tissues. The synchrotron radiation propagation phase contrast micro-CT has been used in 3D imaging methods. However, the simple phase contrast micro-CT did not give sufficient micro-structural information when the specimen contains soft elements, as is the case with many biomedical tissue samples. The purpose of this study is to develop a new technique to enhance the phase contrast effect for soft tissue imaging. Experiments were performed at the imaging beam lines of Pohang Accelerator Laboratory (PAL). The biomedical tissue samples under frozen state was mounted on a computer-controlled precision stage and rotated in $0.18^{\circ}$ increments through $180^{\circ}$. An X-ray shadow of a specimen was converted into a visual image on the surface of a CdWO4 scintillator that was magnified using a microscopic objective lens(X5 or X20) before being captured with a digital CCD camera. 3-dimensional volume images of the specimen were obtained by applying a filtered back-projection algorithm to the projection images using a software package OCTOPUS. Surface reconstruction and volume segmentation and rendering were performed were performed using Amira software. In this study, We found that synchrotron phase contrast imaging of frozen tissue samples has higher contrast power for soft tissue than that of non-frozen samples. In conclusion, synchrotron radiation propagation phase contrast cryo-microCT imaging offers a promising tool for non-destructive high resolution 3D histology.

The aim of this study lies on verifying the mediation effect of organizational justice in the relationship between R&D personnel's job characteristics and organizational performance within their Government-sponsored research institute. For this, a survey was conducted on 362 R&D personnel members from 25 state-sponsored research institutes under National Research Council of Science & Technology, and then, a multiple regression analysis was used to seek any possible relationship. As a result, job characteristics such as autonomy and feedback were found to have positive (+) influence on organizational commitment. In addition, the result of the mediation effect of organizational justice indicated that the impact was made only by autonomy. This study finds its significance in the fact that it revealed the relationship between job characteristics and job satisfaction among R&D personnel in state-sponsored research institutes who have rarely been the source of objectives in related studies, and that it revealed organizational justice mediated the relationship.

The purpose of the present study is to investigate the structural relationships of work-family culture, work-family balance and organizational commitment among Korean hotel employees. In order to achieve the study goal, frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis and covariance structure analysis were undertaken using SPSS(18.0) and AMOS(18.0). The results showed that 'managerial support' had a significantly positive effect on work-family balance, and 'fewer negative career consequences' had a significantly positive effect on affective organizational commitment. In addition, work-family balance had a significantly positive effect on affective organizational commitment, Hence, in order to enhance employees' affective organizational commitment, the atmosphere in which employees can take advantage of family-friendly policies without any worry about the future disadvantages should be built. Also, management has to consider employees' work-family balance to be important and needs to develop various policies to keep employees' work and family stability.

In this study, we analyzed the effects of how Human resource management affects the knowledge sharing that facilitates organizational performance. Human resource management has received very little attention in the study of knowledge management. However, main drivers of knowledge activities are individual members of an organization and thus knowledge management strategies should be discussed in relation with human resource management. The results show that human resource management was significantly positively related to knowledge sharing, and the relationship between human resource management and organizational performance was partially mediated by knowledge sharing. Lessons and implications of this study for management leadership are presented.
