This study aims to investigate the impact of workplace safety on doctors' retention and turnover intention along with job satisfaction as the mediator. A questionnaire-based survey was conducted with 394 medical doctors working in thirty-five hospitals in Pakistan using a structural equation modeling. Results of the study showed that: 1) workplace safety has a significant positive relationship with employee retention; 2) workplace safety has a significant negative relationship with turnover intention; 3) workplace safety has a significant positive relationship with job satisfaction; 4) job satisfaction has a significant positive relationship with employee retention; 5) job satisfaction has a significant positive relationship with turnover intentions; 6) job satisfaction mediates between workplace safety and employee retention; while 7) job satisfaction failed to mediate between workplace safety and turnover intentions. The findings of the study suggest that in a fear-free and safe environment, employees' chance to stay will increases. The study also suggests that dissatisfied employees do not need to leave the organization. There can be other factors that can be explored in future studies. This study also provides a practical implication for the doctors' low retention and high turnover, specifically in the healthcare sector of Pakistan by providing guidelines to the human resource executives to focus on the strategic implementation of workplace safety.

In the construction industry, due to the nature of the job, the need for job training to maximize the performance of the job and to improve the organization's qualifications is needed to acquire professional knowledge that is practiced according to the training needs of the members of the organization. In the form of education, the government or the government or the government provides systematic and planned professional job training that is implemented to improve qualifications and instill pride in the profession by helping the employees of the design office acquire new knowledge, skills, and attitudes necessary for professional performance. Although it is recommended at the organizational level, as a result of examining the implementation, it was found that most workers did not receive job training activities. Therefore, follow-up studies that can maximize work efficiency at the individual and organizational level of design office workers should be continuously performed.

Recently, supercomputer has been increasingly adopted as a computing environment for scientific simulation as well as education, healthcare and national defence. Especially, supercomputing system with heterogeneous computing resources is gaining resurgence of interest as a next-generation problem solving environment, allowing theoretical and/or experimental research in various fields to be free of time and spatial limits. However, traditional supercomputing services have only been handled through a simple form of command-line based console, which leads to the critical limit of accessibility and usability of heterogeneous computing resources. To address this problem, in this paper, we provide the design and implementation of web-based HPC (High Performance Computing) job management framework for computational scientific simulation. The proposed framework has highly extensible design principles, providing the abstraction interfaces of job scheduler (as well as bundle scheduler plug-ins for LoadLeveler, Sun Grid Engine, OpenPBS scheduler) in order to easily incorporate the broad spectrum of heterogeneous computing resources such as cluster, computing cloud and grid. We also present the detailed specification of HTTP standard based RESTful endpoints, which manage simulation job's life-cycles such as job creation, submission, control and status monitoring, etc., enabling various 3rd-party applications to be newly created on top of the proposed framework.

This study was conducted to determine the relationship between the job stress levels of 669 subway operators in Seoul after the installation of screen doors and their mental health. Data were collected using a structured questionnaire and via web site. A multiple linear regression analysis was conducted using the SPSS 20.0 statistical program. The total score of job stress turned to be higher than the standard score, and physical environment, job demand, insufficient job autonomy, interpersonal conflict and occupational climate were within the top 50% and organizational system within the top 25%. A correlation analysis revealed that job stress was positively correlated with all sub-domains of mental health. In terms of effects of job stress on mental health, there were significant differences according to job demand, organizational system, lack of reward and occupational climate, with an explanatory power of 36.6%. It is expected that this study can provide foundation for the establishment of organizational measures accustomed to job characteristics to prevent job stress of subway operators and the development and implementation of intervention programs for mental health promotion.

When a tractor travels slope lands, problems of operator safety and the reduction of job efficiency usually occur. Therefore, maintaining the tractor body being horizontal is critical to improve the security of traveling and the job performance. An experiment was made in a soil bin using the experimental model system built and equipped with a leveling control system. Adaptability of the control system was tested and investigated by analyzing system response in time and frequency domains. Control response time of hydraulic cylinder with 10lpm flow rate on a step input of 10$^{\circ}$slope was about 0.42sec. And it showed a linearly increasing trend without any hunching state. A steady state error of 0.6$^{\circ}$occurred but it was negligible. The hydraulic control system showed a little phase differences within the range of 0.4Hz input frequency. The experimental model showed that implementation of the proposed tractor control system to on slope lands tractor was feasible.
