Objectives : The purpose of this study was to analyze the relationships among social participation, self-rated health status, self-esteem and daily life satisfaction of the elderly with disabilities. It especially focused on the mediating effects of self-rated health status and self-esteem on the relationship between social participation and daily life satisfaction. Methods : From the fifth panel survey of employment for the disabled, data for 518 elderly over age of 65 were analyzed with SPSS 22.0, SmartPLS 2.0 M3 and the Sobel test. Results : First, social participation of the elderly with disabilities had a positive influence on the self-rated health status and self-esteem. The direct effect of self-rated health status and self-esteem on daily life satisfaction was statistically significant. However, the influence of social participation on daily life satisfaction was not statistically significant. Second, the self-rated health status and self-esteem had a mediating effect on the relationship between social participation and daily life satisfaction. Conclusions : This study shows that it is important to provide an integrated social participation support program that coincides with a variety of social programs to elderly with disabilities.

Purpose: This study aimed to evaluate the performance of Clinical Research Nurses (CRNs) and the importance of their roles at the Regional Clinical Trial Centers (RCTCs). Method: A questionnaire focused on the role of CRNs was crafted by a researcher and the content validity was verified by a panel of experts on clinical research. The subjects of this study were 91 CRNs and Clinical Research Coordinators (CRCs), who were Korean registered nurses working at nine RCTCs. 77 subjects yielded valid data were analyzed using descriptive analysis, the Mann-Whitney U test, Spearman's rank order correlation coefficient, and Kruskal-Wallis test. Results: The performance of CRNs and the recognition in the importance of their roles were statistically significant different in age, education, CRN careers, positions, employment status and the phase of clinical trial. The role of direct caregiver was performed most often by CRNs. The role of coordinator of care and research (pre-study) was considered the most important role but performed the least frequent. Conclusions: The role of CRNs can easily be differentiated from CRCs who are not registered nurses. The domains of CRNs should be clearly identified and established. Moreover, research should be carried out on CRN training programs to cultivate competence in CRNs.

Korea Ministry of National Defense has directed the state-of-the-art technology Forces troops structures that can respond to security threats in all directions through the Defense Innovation 2.0, which aims to reorganize the personnel and organizations in response to population decline. An implement of effective analysis to maintain combat power is necessary due to possible restrictions on combat power, especially in division of mobilization where reserve manpower is operated frequently. In this study, the normal operations of the reserve officers were investigated, the direct effects of the combat forces of the reserve officers was analyzed using ARENA modeling, and the budget required to operate the innovation and indirect effects of employment of veterans were studied. The result of the simulation proved to be effective in demonstrating unit combat power when the reserve officer was in full-time operations and economic benefits were also significant in terms of efficiency of defense budget management.

The purpose of this study is to analyze the effect of sex of supervisor on the stress and promotion of Korean women workers in the workplace using the Korean Women Manager Panel. The results demonstrate that when the direct boss of female workers was female, stress in the workplace was high and the promotion rate of staff and assistant managers was low. According to the theory of queen bee phenomenon and role congruity theory, a structure of glass ceiling and the male-dominated working culture does not require positive qualities of female leadership but requires a high recognition standard or competitiveness. It can be interpreted that the female worker with the female supervisor showed more stress in the workplace and the probability of female promotion in staff and assistant managers is low.

Objectives: To deter job migration and to facilitate a more efficient personnel management system, a personality type analysis tool, such as MBTI and Enneagram, may be considered. These tools can facilitate better recognition of talent among prospective employees, as well as more efficient allocation of tasks for greater job satisfaction. Methods: This study conducted direct interviews with dental hygienists currently employed at two major dental organizations, which operate the largest networks of clinics across the greater metropolitan area. Results : First, in terms of number of turnover experiences, the Head Type showed lower task satisfaction, whereas the Body Type exhibited greater task satisfaction. Second, the Head Type showed greater job satisfaction compared to the other types. Third, the SJ Type, often considered the traditionalist in terms of long-term employments, exhibited greater tendencies toward long-term commitment with one employer. Fourth, dental hygienists, in terms of long-term employment, are negatively affected by task satisfaction, and positively affected by job satisfaction. Conclusions: It is thought to be considerable to use personality type analysis tools in clinical human resource management.

This paper presents the test results of total 35 direct tensile specimens to investigate the effect of high-strength concrete on the tension stiffening effect in axially loaded reinforced concrete tensile members. Three kinds of concrete strength 25, 60, and 80 MPa were included as a major experimental parameter together with six concrete cover thickness ratios. The results showed that as higher strength concrete was employed, not only more extensive split cracking along the reinforcement was formed, but also the transverse crack space became smaller. Thereby, the effective tensile stiffness of the high-strength concrete specimens at the stabilized cracking stage was much smaller than those of normal-strength concrete specimens. This observation is contrary to the current design provisions, and the significance in reduction of tension stiffening effect by employment of high-strength concrete is much higher than that would be expected. Based on the present results, a modification factor is proposed for accounting the effect of the cover thickness and the concrete strength.

This paper aims to discuss the concept of resilience in floating housing, to investigate the resilient features of floating houses & to review the possibility of floating housing as a new form of resilient living, and to suggest some reference ideas for the planning and design of floating housing projects. Resilient features of the floating house can be summarized as the buoyant characteristics for natural disasters, the easy employment & potential use of renewable and nearly self-sufficient energy systems in locations subject to limited energy sources, the movability, mobility, long life, water recycle system, prefabrication and modular construction with the potential for reduced environmental impact. Additional benefits include the potential for a peaceful and comfortable atmosphere due to direct connections with nature, good relationship with neighbors, a solid social spirit of unity, and sense of security. Considering the resilient features of floating house at a time of serious climate change requires a new paradigm, and floating/amphibious/floatable housing has great possibility as a new form of resilient living.

The demand of large capacity in coming cellular systems makes inevitable the deployment of small cells, rendering more frequent handoff occurrences of calls than in the conventional system. The key issue is then how effectively to reduce the chance of unsuccessful handoffs, since the handoff failure is less desirable than that of a new call attempt. In this study, we consider the control policies which give priority to handoff calls by limiting channel assignment for the originating new calls, and allow queueing the new calls which are rejected at their first attempts. On this system. we propose the problem of finding an optimal call control strategy which optimizes the objective function value, while satisfying the requirements on the handoff/new call blocking probabilities and the new call delay. The objective function takes the most general form to include such well-known performance measures as the weighted average carried traffic and the handoff call blocking probability. The problem is formulated into two different linear programming (LP) models. One is based on the direct employment of steady state equations, and the other uses the theory of semi-Markov decision process. Two LP formulations are competitive each other, having its own strength in the numbers of variables and constraints. Extensive experiments are also conducted to show which call control strategy is optimal under various system environments having different objective functions and traffic patterns.
