For the construction safety manager, it is expected that job stress is significantly high due to lack of expertise about new technology, new construction methods, and enlargement of scale as well as due to work intensity and unstable work hours. It is probable that such an increase in job stress not only has bad effects on individual, but also the bad effects spread to construction industry at large, resulting in rise in accident rate, increase in direct and indirect loss cost, and loss of reputation. In this context, methods for controlling construction safety manager's job stress are needed at the levels of both government and company. Therefore, this study investigated and analyzed the effects of construction safety manager's job stress on job satisfaction and job commitment, and proposed methods for relieving job stress. In addition, this study was suggested policies for higher job satisfaction and job commitment at the levels of the government and companies.

Many emerging mobile ad-hoc network application communications are group-oriented. Multicast supports group-oriented applications efficiently, particularly in a mobile environment that has a limited bandwidth and limited power. Energy effectiveness along with safety are 2 key problem in MANET design. Within this paper, MANET is presented with a stable, energy-efficient clustering technique. In this proposed work advanced clustering in the networks with ticket ID cluster manager (TID-CMGR) has formed in MANET. The proposed routing scheme makes secure networking the shortest route possible. In this article, we propose a Cluster manager approach based on TICKET-ID to address energy consumption issues and reduce CH workload. TID-CMGR includes two mechanism including ticket ID controller, ticketing pool, route planning and other components. The CA (cluster agent) shall control and supervise the functions of nodes and inform to TID-CMGR. The CH conducts and transfers packets to the network nodes. As the CH energy level is depleted, CA elects the corresponding node with elevated energy values, and all new and old operations are simultaneously stored by CA at this time. A simulation trial for 20 to 100 nodes was performed to show the proposed scheme performance. The suggested approach is used to do experimental work using the NS- simulator. TIDCMGR is compared with TID BRM and PSO to calculate the utility of the work proposed. The assessment shows that the proposed TICKET-ID scheme achieves 90 percent more than other current systems.

Purpose: The purpose of this study was to identify the influences of type D personality, burnout and work environment on nurses' intention to stay at the hospitals among nurses. Methods: A cross-sectional descriptive design was used. Participants were 135 nurses working at general hospitals. Data were collected using self-report questionnaires. Data were analyzed using the SPSS/WIN 23.0 program for descriptive statistics, independent t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation, and hierarchical multiple regression. Results: The score of nurses' intention to stay was 4.78. 39.3% of participants were classified as type D personality group. The scores of burnout and work environment were 2.92 and 2.39, respectively. Intention to stay was negatively correlated with burnout and positively correlated with nurse participation in hospital affairs, nursing foundations for quality of care, nurse manager ability, leadership, and support of nurses, staffing and resource adequacy. Burnout and manager ability, leadership, and support for nurses explained 46.0% of variance of nurses' intention to stay in the hospitals. Conclusion: The results of the study indicate that nursing intervention programs for increasing intention to stay for nurses should include strategies for decreasing the burnout and increasing manager ability, leadership, and support for nurses.

The study is conducted in order to establish validity of industrial safety field's neo-qualification composition by suggesting reengineering procedure of NCS based industrial safety field's qualifying occupational plan. Industrial safety fields are first classified into great classification which are environment energy safety, and then into sub-classification which are industrial safety management, industrial health management, and nondestructive test. NCS based neo-qualification plan is deveopled into progress as following steps; First, planning NCS neo-qualification system. Second, presenting work education combined program certification standard. Third, developing NCS based neo-qualification assessment standard. Fourth, developing work education qualification prototype problem. The process of qualification plan was composed with Worksheet 14 and with 4phase being completing summary of each section, certification and development of assessment standard, and development of prototype problem. As a result, Industrial safety manager was redesigned into Industrial sfety manager and Construction Safety Manager, and Occupational Health Care Manager was redesigned into Occupational Health Care Manager and Industrial Health Manager. This study, in conclusion, suggests development of qualifying occupation that could be applied to the integrated management system and development of future industrial safety field's specialized neo-qualifying occupation.

Objective: This study aimed to investigate the influence of child care center managers' coaching leadership on teachers' motivational self-concepts via middle managers' coaching leadership. Teachers' motivational self-concepts consisted of personal self-concept and social self-concept. Methods: A questionnaire survey was conducted on 475 child care center teachers regarding teachers' recognition of the coaching leadership of managers and middle managers and motivational self-concepts of teachers. To analyze the collected data, the path was examined through descriptive statistics, correlation analysis, structural analysis using Amos, and the mediating effect was confirmed by conducting the Sobel Test. Results: The middle manager's coaching leadership was found to mediate the pathways from the manager's coaching leadership to the teacher's social self-concept, but did not mediate the personal self-concept of teachers. Conclusion/Implications: This study showed that the manager's coaching leadership was mediated by the middle manager's coaching leadership and that the manager's coaching leadership had an influence on the social self-concept of teachers. These results imply that both managers and middle managers need to develop coaching leadership skills in order to improve the motivational self-concept of teachers, which is important for work efficiency at child care centers.

In this study, the relative importance for the perception of managers on the comprehensive rural village development projects was evaluated using the AHP method. The fields for evaluation were 4 fields including human relationships, working conditions, work compensation and work burnout. Also, the relative importance for the perception of managers and priority order were analyzed through 15 evaluation items. The analysis result shows that the human relationships among 4 fields were regarded as the most important field, followed by work compensation, working conditions and work burnout. Also, the relationship with the chairperson for the human relationships, continuity of employment for the working conditions, salary for work compensation, and mental stress for work burnout were considered respectively as the most important item. Also, salary among all evaluation items was considered as the most important item for the relative importance, followed by continuity of employment, relationship with village residents and mental stress. However, work load, consulting firms, impersonal treatment and the relations between the administration showed relatively low importance and priority order. It is considered that this analysis result will be used as important preliminary data for establishing the role of manager in the comprehensive rural village development project.

In this paper we developed a CCM Manager which is a management system to support efficient development, publication and promotion of Clinical Contents Model(CCM)'s outcomes. We derived the functions of manager and user from the analysis of work process from development of CCM to management and publication, designed the database based on CCM architecture, and developed web-based system for each user to easily access and search the contents. CCM Manager supports to share the results between model developers well, distribute and promote the outcomes of model type to general users without manager's manual packaging and publishing it. This paper shows superiority compared with other clinical information model management system in aspects of providing multiple search functions, visual model browsing methods and management functions. The proposed CCM Manager is currently used in process of CCM development, and the analysis of its efficiency with the results will be made in the future.
