Purpose: This study concerns the cost of safety management in order to prevent accidents and disabilities in the construction industry. The purpose of the Chapter is to draw up problems and improvement measures for these safety management costs. Method: A detailed questionnaire was developed for 20 construction safety managers for the research. This questionnaire was analyzed and implemented by the Expert Group Interview (FGI) analysis method. Results: In order to understand the safety management cost system, alternatives such as preparing a standard manual, implementing regular on-site training, and establishing a monitoring system for the safety management cost were derived. In addition, there is a need to ensure autonomy in the execution of flexible costs so that they can be deployed immediately in case of emergency to improve the 'efficiency and necessity of the safety negligence system'. And it was analyzed as items that should be improved due to excessive demand for documentation. Conclusion: Through this study, problems should be recognized for the improvement of the construction safety management cost system. And it will have to come up with policy-based and institutional-improvement measures for experts.

The purpose of this study, which was conducted as a part of investigations for vitalizing the School Sheriff system proposed as a means to prevent school violence and promote school safety, was to survey recognition of elementary school parents toward the School Sheriff system and present an improvement scheme for the system. For the study, we selected as the research object a set of parents whose children attended schools with School Sheriffs and then sampled 200 parents out of them with cluster random sampling, before analyzing 189 finally. Validity of the questionnaire is verified by expert council and factorial analysis, and reliability by reliability analysis. Statistical means including chi-square test, t-test and F-test are used. The result of the study as follows : First, necessity of the School Sheriff system varies by individual characteristics. Second, recognition toward the system itself varies by individual characteristics. Third, recognition toward the role that should be played by School Sheriffs varies by individual characteristics. Fourth, there is a difference in perceiving the role and activity of School Sheriffs, Fifth, whether the system helped improving school safety varies by individual characteristics. Sixth, the satisfaction from the School Sheriffs.

While local autonomy is settled, each local government plans and fulfills policy to foster local industry for local development so it is important to establish industry location and economic foundation which is fitting to local conditions. Local development requires the development of local industry and it is necessary that this industry fits to the local conditions in order to be focused and developed. The regional input-output tables contain very useful data to understand the structure of local industry and interregional industry and also the analysis of linkage by industrial ripple effect among regions is needed. The study divided the country into 7 units and conducted factor analysis by using sum data of inducement coefficients in 78 parts of 2005's regional input-output tables, and as conclusion extracted 8 factors.

The purpose of this study is to analyze traffic accident reduction effect of the introduction of motorcycle safety inspection. To analyze the effect of motorcycle inspection, we first estimate the number of defective motorcycles, and calculate the probability of accident occurrences caused by the defect using four year traffic accident data. Finally, we estimate the number of reduced accidents due to the introduction of the inspection and the total reduced accident cost. In this study, we analyzed three scenarios. It is analyzed that when the safety inspection system is applied to all motorcycles, 642 cases of traffic accidents and 325 million won per year of traffic accident costs are reduced. It is approximately 0.1% of 2014 total traffic accident cost of 26.5725 trillion won per year. It suggests that the cost of traffic accidents and traffic accidents due to vehicle factors are reduced when the safety inspection system is introduced.

Diversification of college admission system has recently brought up the problem of system fairness. Studies on fairness of college admission system mainly focused on policy proposal or investigation of teacher's perception. Different from previous works, this study aims to analyze college students' perceptions of fairness of the current college admission system. This study used grounded theory and interviews from eleven students. Results of analysis are as follows. Causal condition proved to be frequent change in admission system happened in the course of diversifying admission criteria. The core phenomenon is fundamental unfairness in both procedural and substantive aspects of admission system. Contextual condition is information and infrastructure asymmetry among students which has a root in regional gap in Korea. Mediatory condition is advance of information technology and individual or group effort to overcome disadvantages. In conclusion, students consider that unfairness in college admission system reflects social structural problems that cannot be solved in a one-time prescription.

After forming a institutional framework with specified in Maritime Safety Law(ex. Maritime Traffic Safety Law) on May 27th, 2009, The efforts for improving 'Maritime Traffic Safety Assessment Scheme(MTSA scheme)' have continued to the present. But there's no review with the comprehensive and systematic approach for proceeding acceleration step of MTSA scheme. At this point, this study analyzed current status and derived improvement measures using by 'PIP'OU model' which was designed for the comprehensive analysis in accordance with metaevaluation theory, like as question investigation and etc. Consequently, it mainly needs to improve 'Assessment Plan' domain and minimized the difference in views between concerned parties. This study is expected to be used to develop systematic maritime policy by proposing the order of priority in improvement matters.

Complicated political situation still plagues charter schools despite their innovative education. Nevertheless, they experienced growth around 2011, yet only a few studies have explored why they had expanded from the political viewpoints. Therefore, using political institutions and political market framework, this study investigated the relationship between political institutions and charter school growth in the US(United States). To do so, this study conducted multiple regression analyses of school growth measured by the number of schools allowed, implementation points, and guaranteed funding. The findings revealed that only governors' partisanship has a significant influence on the number of schools. Moreover, supportive privatization organizations, governors' partisanship, and per capita income affects implementation points. Meanwhile, regarding guaranteed fiscal funding for the charter schools, the teachers' union enrollment rate, governors' partisanship, and per capita income are crucially influential. Finally, the results confirmed that political institutions are also important for education.

In this study, measurement and analysis results from Differential scanning calorimetry(DSC) and Thermogravimetric analysis(TGA) on the newly developed high-energy thermoplastic elastomer(ETPE) propellant are described, followed by the previous study done under the same title as this paper [1]. The characteristics of high-energy thermoplastic propellant were also verified by conducting thermal analysis, and the LSGT, Shotgun & RQ Bomb test, was carried out as well. High energetic thermoplastic binders containing 45% of GAP(Glycidyl Azide Polymer), energetic plasticizer(DEGDN) and Oxidizer Aonium Perchlorate), RDX(reseach development explosive, cyclotrimethylenetrinitramine) were used to formulate the propellant.
