The purpose of this study is to investigate the impact of members' perception of unit change management efforts on their emotional-organizational commitment during the military restructuring. The mediating effect of change acceptance of the members in this relationship is also studied. Currently, the military is seeking to restructure its military construct in order to actively cope with the rapidly changing security situation and the decrease in military service resources. If an organization fails to effectively manage its changes when undergoing restructuring, it is difficult to expect the success of organizational change due to its members' resistance to change. Therefore, this study suggested the effect of members' perception of personnel fairness and transformational leadership on their emotional-organizational commitment and the mediating role of the members' change acceptance in the relationship between them as the hypotheses. Survey results show that personnel justice and transformational leadership has a positive impact on the emotional-organizational commitment of the members, and that the change acceptance of the members partially mediates the relationship between them. By presenting the mediating effect of change acceptance with theoretical implications, the theory has been expanded. In practice, the change management activities for the restructuring of the military structure have been identified, and the effort for enhancing the change acceptance of the members is required to success on the organizational restructuring.

The Korea Maritime Police Agency(KMPA) is the national maritime Search and Rescuee (SAR) authority with the responsibility to promote an efficient organization of SAR services and to coordinate the conduct of SAR operations within the Korean Search and Rescue Region(SRR). The maritime SAR operations shall provide an adequate and effective search and rescue services to minimize the loss by rendering aid to persons in distress and property in the marine environment. The essence of a successful search and rescue operation is the speed with which it is planned and carried out because survivors who need assistance and whose chances of survival diminish rapidly with time. This paper aims to propose an optimal allocation model of maritime SAR fleet in view of minimizing the search and rescue time. When maritime accidents occur, rescue units have to reach to the distress scene within the specified time. For this, SAR units must be redeployed to an advanced base so that Rescue Units(RU) can reach to the scene of distress in the shortest possible time. The Korean maritime SRR is divided into 180 sub-areas in consideration of an operational and technical ability of SAR units. The suggested model is verified through an empirical application to the Korean maritime SRR. And also the Rescue Vessels(RV) required is estimated for each Rescue Co-ordination Center(RCC).

Taking 195 Korean businesses and sorting them out according to the unit types, this study looks into how flexibility strategy in labor market, which consists of numerical flexibility and functional flexibility, takes effect on the organization's outcome variable, which in turn consists of productivity, labor-management cooperation, and job security. In addition, the present study analyzes the role of labor union's moderating effect on the relationship among labor market flexibility, labor-management cooperation, and job security. It is found out as a result that numerical flexibility has no meaningful relation with productivity, labor-management cooperation, and job security, while functional flexibility has a considerably positive relation with them. This result confirms the importance of functional flexibility of business strategy in labor market. The West has continuously insisted the importance of functional flexibility, pointing out problems of numerical flexibility. On the other hand, considering that this study has confirmed functional flexibility's meaningful relation, while it has not found out numerical flexibility's negative relation, it is necessary to study further on the relationship between these two kinds of flexibility. The result of analysis on the role of union power's moderating effect confirms only the union power's interaction effect in the relation between numerical flexibility and labor-management cooperation. The possibility of union's opportunistic behavior can be detected in this result.

The construction of National Spatial Data Infrastructure (NSDI) started from 2008 and was completed at 2012, with the aim of co-utilizing public agencies' national spatial information by integrating and linking. Despite the existence of the NSDI, an update of spatial data is not fully reflected because the spatial information has not been updated simultaneously by NSDI and public agencies. By examining the public agencies' services using the spatial information, a national budget is wasted because the re-usable similar services are duplicated. These issues could be solved by adopting a cloud system, whose concept is co-utilizing IT resources, to the NSDI. This study examined the service cloud based expansion and development plan for NSDI. The plan included an implementation strategy for a spatial information service cloud system and an establishment plan for a governance system. The service scenarios, concept diagram, and service functions for the system were derived in a system implementation plan. For the service functions, the unit functions of two modules were proposed and specific functions were derived. In the establishment of a governance system, the business roles and business processes were defined for organizations managing service cloud based NSDI. The business role and process were defined and derived by each service life-cycle step. With the proposed system implementation plan, a detail system design and composition of the organization could be possible, and a service cloud-based NSDI system could be implemented.

Purpose: The aim of study was to estimate the hand hygiene (HH) compliance of healthcare workers (HCWs) in a children's hospital. Methods: This study was conducted in a hospital which is a tertiary and educational children's hospital with 313 beds and 533 HCWs. Data were collected by direct observation methods from November 1, 2010 to December 31, 2010. Results: A total of 2,999 opportunities for HH were observed, and the overall HH rate was 95.3%. HH rate of the registered nurse, physicians and transferer was 97.7%, 89.2%, and 72.1%, respectively (P<0.001). Among physicians, HH rate of the fellows, professors, residents and interns was 97.5%, 93.9%, 89.7%, and 80.9%, respectively (P<0.001). HH rate in the emergency room, operation room, outpatient department (OPD), and the intensive care unit (ICU) was 97.2%, 97.2%, 95.4%, and 92.5%, respectively (P<0.001). Hand rubbing was the most frequently used (81.1%), and hand washing was frequently used in the case of 'after body fluids exposure risk' (37.7%) and 'after touching patient surroundings' (28.5%). HH methods were not statistically different from each departments (P =0.083), however, they were significantly different according to the World Health Organization (WHO) 5 Moments (P<0.001). Distributions in WHO 5 Moments by the job titles were significantly different (P<0.001). The odds ratio of physicians, ICU and OPD was 0.353 (95% CI, 0.241-0.519), 0.291 (95% CI, 0.174-0.487), and 0.484 (95% CI, 0.281-0.834), respectively. Conclusions: Compliance of HH was different by the job titles and departments. Effective custom-tailored HH programs for each job title and department need to be developed.

The estimation of PMP (Probable Maximum Precipitation) and the analysis of characteristics of PMF (Probable Maximum Flood) according to the types of time distribution of rainfall and variations of base flow for the determination of design flood of major hydraulic structures in the watershed area of Wi stream were analysed. The PMP was estimated by the hydro-meteorological method suggested by the guideline of the World Meteorological Organization(WMO). The Blocking method was cited to transpose from PMP to PMS (Probable Maximum Storm) with time distribution. The unit hydrograph, applied for the estimation of PMF was derived by Clark's method. The summaryzed results : (1) The 72 hrs duration PMP in the area is 477.3mm which is 80mm less than the PMP map in Korea and 134 mm lager than the maximum precipitation of 342.9mm in Taegu, near the Wi stream watershed. (2) According to the types of time distribution and variations of base flow, the ranges of PMF for advanced type, central type and delayed type are 3,145.3~3,348.3cms, 3,774.6~3,977.7cms and 3,814.6~4,017.3cms, respectively. Those mean that peak discharge of advanced type is 600cms less than the central type and delayed type. (3) Delayed type among three types by Blocking method has been estimated the largest PMF of 4,017.3cms, and the advanced type has been estimated the smallest PMF of 3,145.3cms. The mean value of the peak PMF of 3,653.6cms may probably be resonable PMF in the Wi stream watershed. The mean PMF could probably be 1.7 times lager than the result of Gajiyama's equation. It is equivalent to the flood of return period 1,000 to 10,000 yrs.

International Maritime Organization (IMO) is one of the most effective organizations in evolving international law for the protection and conservation of the marine environment. The IMO, MARPOL(Marine Pollution) 73/78 contains six Annexes that provide an overarching framework for the objectives of the international marine pollution. Annex IV was regulated by 64 th resolution in 2012 to control sea pollution from sewage. In 2014 large-scale wastewater treatment and nutrient removal device was developed with a grant from the Ministry of Oceans and Fisheries. A combined new process of Sequence Batch Reactor (SBR) and Membrane Bioreactor(MBR) was developed to overcome the pollution caused by shipboard sewage. In the present study, shipboard sewage wastewater was treated by mixing and aeration cycle in the newly developed SBR process. Furthermore, during analysis by NGS technique(Macrogen Co., Ltd.), dominant species of bacteria were found in the aeration tank of the Bench-scale wastewater treatment facility. Bacteroidetes and Gammaproteobacteria accounted for 27.1 % of the aerobicbacteria and 16.8 % of the anaerobicbacteria, respectively. Microorganisms play a vital role in shipboard wastewater treatment. A further detailed study is required to understand the precise role of the microorganisms in the wastewater treatment.

The purpose of this study is to propose implications by analyzing the textiles and clothing curriculum of vocational high schools. Literature and data were analyzed, surveys and FGI were conducted, and the following research results were derived. First, many schools chose 'Basic dress design' or 'Basic dress composition' as basic subjects. Through this, it was confirmed that technical training for practice is a priority for vocational schools, and that more discussion is needed regarding the lack of theoretical subjects. Second, similarly to the basic subjects, practical subjects offered are concentrated on 2 to 3 subjects. The teachers asserted that some subjects such as 'Knit apparel production' and the 'Leather and fur design production', which require a lot of equipment and advanced technology, cannot be offered without support from the government. Third, the NCS competency unit of the practical subjects is easy to proceed with the class or is closely concentrated on the type of manpower training presented by each department. Fourth, this study proposes that for technical education to expand students' choice, it is necessary to cultivate teachers competencies linked to the industry. The results of this study are expected to provide basic data on the organization of the next textiles and clothing professional curriculum and help understand vocational education at vocational high schools. In addition, it is believed that this study will contribute to developing and settling various subjects when the high school credit system is implemented by expanding students' choice of major-related subjects.

The purpose of this study was designed to help the operation of the hospital organization through analysis of factors influencing organizational commitment of general hospital nurses. 129 nurses in general hospitals were targeted in G City. This study was conducted to analyze the effects of group efficacy, self-efficacy, and nursing professionals on organizational commitment. T-test, ANOVA, Pearson's correlation coefficient, Descriptive statistics and multiple regression were used. Stepwise regression analysis found that organizational commitment was affected by group efficacy(β=0.240, p =.003), nursing professionalism(β=0.229, p =.004) and daytime work(β=0.249, p =.003), The F statistic was 10.478 (p <.001). Therefore, in order to improve organizational commitment, it will be necessary to prepare communication programs and cooperation programs per unit to improve collective efficacy. In addition, it is necessary to improve the system, such as a system dedicated to night workers, so that the working hours of nurses in general hospitals can be maintained constant. In addition, it is necessary to develop a support program so that nursing professionals do not decrease due to disappointment in reality in the nursing field.
