The farming and fishing village roads is located in a mountainous geographical feature, a resident's movement zone is followed by many restrictions in economic activities or social activities. Establishment of general planning gets into guide of long-term development direction for road in farming and fishing villages area. This study examined and analyzed a regional characteristics such as a regional environment and traffic condition, etc. and an actual condition of farming and fishing village roads, selected a factor affecting a priority to open a road, calculated a weight per each factor by AHP & Statistical analysis techniques, converted it into GIS database, and determined a priority for paying forming and fishing village roads. It is that development precedence and estimation calculation are decided applying result of research, GIS and AHP and statistical processing techniques.

Korea is constructing the disaster management system to prevent various disasters and minimize damages. In spite of these efforts, however, Korea lately suffered from a number of diverse disasters. These disasters once again lead to the questions and criticisms concerning the effectiveness of the disaster management system. So research into how to quantify the disaster management system is very significant in securing the right of the people to lead a safe life, keeping human life and properties from being injured. The purpose of this study is to prioritize policies which can be considered for establishing and operating disaster management system. To do that, this study conducts a questionnaire survey, targeting for 282 fire man. The survey includes various factors according to four stages in disaster management process: prevention, preparedness, response and recovery. The method used is AHP(Analytic Hierarchy Process) technique using expertchoice 2000. Results of the analysis are as follows. At the first stage of analysis, prevention is found as the most significant factor. The other significant factors are response, preparedness, and recovery factor in order. At the second stage of analysis, share of role among disaster facilities is the most significant factor. Reorganization of disaster facilities and connection of law are significant in order.

This study choose the Criteria by conducting survey questionnaire of expertise, ANP analysis, and reviewing literature to samples of School Zone in a synthetic and reasonable way. It draws the estimating factors including a variety of existing aspects (user, facility, operation and management, and education and institution) from the analyses and applies ANP to reflect the decision making process. The results show as follows: first, first level of weights presents proportion of 'facility' and 'user' takes 65% of total weights. It implies that the facility protects children from obstacles is the top priority of the settings. second, the second level of weights present similar importance with the first level. Facility management, road to school, surroundings, safety facility, decelerating facility hold approximately 72% of overall levels. This indicates that improving and repairing surroundings, and safety and decelerating facility are the first priority to consider. These estimating indicators will be properly utilized to rationally appoint prevention zone with reflecting various factors and social class.

본 연구는 농업지역의 가뭄 발생에 대하여 활용되는 관정의 효율적 관리를 목표로 우선관리가 필요한 취약지역을 선정하는 방안을 수립하였다. 특히 한국에서는 논 위주의 농업 생산기반정비가 진행되어 왔으나 최근 경제성장과 소득증대에 따른 농산물 소비 구조의 변화로 다양한 밭 작물경작이 증가하여 밭 관개시설물에 대한 정비가 요구되고 있다. 따라서 가뭄 대응을 위한 밭작물의 용수공급 시설물인 관정에 대한 취약성 평가를 통하여 관리의 목표와 우선관리 지역의 선정이 필요하다. 가뭄에 대한 관정 취약성 평가는 최근 널리 사용되는 다기준의사결정 기법인 TOPSIS를 적용하였으며, 한국 전역 158개의 시, 군을 평가대상으로 한다. 평가 인자는 관정능력 및 효율에 긍정적 영향을 주는 강수량, 지하수위, 관정 당 양수량과 부정적 영향을 주는 경지면적, 연속무강우일수, 민간관정 비율을 선정하였다. 평가결과로부터 관정 당 양수량과 상수도 보급율이 관정 효율 취약성 평가를 통한 우선 관리 순위선정에 주요한 영향을 주는 것으로 분석되었다.

In March 2016, the Korean National Assembly passed the Counterterrorism Act called as "Counterterrorism Law for the Protection of the People and Public Safety", and relevant functions and roles of the counterterrorism institution were granted based on the law. However, a number of problems have been raised in the course of the job performance of the counterterrorism related institution, and various improvements have been discussed. This study conducted 'Analytic Hierarchy Process(AHP)' on the experts to identify the issues related to the improvement possibilities of the counterterrorism system that had been discussed previously. The results of the analysis to improve the current counterterrorism system are as follows. First, the priorities of the top factors were identified as in the order of legal institutions, cooperation, and operational aspect. Next, the priorities of the individual sub-factors were identified as the reorganization of the counterterrorism task force, the organic cooperation of domestic counterterrorism institution, and the cultivation of specialized human resources for anti-terrorism work. It was found that we should discuss the reorganization of counterterrorism institution as a policy consideration to improve the counterterrorism system.

In this paper, we propose operations and maintenance (O&M) planning approach for floating offshore wind farm using the mathematical optimization. To be specific, we present a MILP (Mixed Integer Linear Programming that suggests the composition of vessels, technicians, and maintenance works on a weekly basis. We reflect accessibility to wind turbines based on weather data and loss of power generation using the Jensen wake model to identify downtime cost that vary from time to time. This paper also includes a description of two-stage approach for maintenance planning & detailed scheduling and numeric analysis of the number of vessels and technicians on the O&M cost. Finally, the MILP model could be utilized in order to establish the suitable and effective maintenance planning reflecting domestic situation.

Most of all Castle Remains in Korea were built on an axis of development with a scale of great magnitude. Because of its characteristics, the restoration and conservation plans should be phased in over medium and long term. There is no standards for evaluating the value of Castle Remains to set up the restoration and conservation sections. Some plans were set up through the value evaluation of its Castle Remains but those plans didn't have Evaluation System and different weight depending on different environment between Sanseong(mountain fortress) and Eupsung(fortress built in villages). To solve the limitation of Evaluation System of Castle Remains, this study try to approach in the Evaluation System methodology for selecting restoration sections. The results of its study follow below. First, this study drew the Evaluation Indices for selecting restoration sections of Castle Remains. There are three kinds of Elements(upper Index) and nine kinds of Evaluations(low Index). Second, Calculation of weight index by index on the questionnaire survey from expers through the relative importance analysis of AHP. Third, This study suggests the specific Evaluation System according to types; Sanseong(mountain fortress) and Eupsung(fortress built in villages);. Therefore, this study suggests standards to select the priority list for the restoration and conservation plan process and it can be used one of important standards in future plans.

One of the important roles used to ensure victory in a war is to maximize the overall military forces and to make sure that the capability of the military forces can be sustained as much as possible. Although several researchers have proposed various possible methodologies for logistics support, no research trials have been undertaken to investigate logistics support that considers all relevant elements of such. Unlike previous in trials that consider and analyze the system fault ratio as the main methodology, we propose an approach that simultaneously decides and recommends logistic priority by reflecting and combining item costs, transportation, fault-ratio, and system complexity. Also, we designed an algorithm that can recommend optimized logistics support priority using stationary distribution.

Korea Hydro & Nuclear Power Co. (KHNP) has implemented engineering programs for operating nuclear power plants. Engineering programs are maintenance rule (MR), functional importance determination (FID), single point vulnerability (SPV) and functional equipment group (FEG). Recently, KHNP has developed engineering programs for APR1400 feedwater supplying system to establish the advanced engineering system and will verify the suitability of engineering programs through implementing in new nuclear power plant. Consequently, it is expected that the reliability of APR1400 feedwater supplying system will be improved by implementing engineering programs.
