본 논문은 재난관리의 성과에 대한 근원적 의문에 대한 문제제기에서 출발하였다. 재난관리의 성과는 재난에 대한 정부의 관리적 측면, 즉 행정관리 역량이나 산출지표 등으로 평가되어 왔다. 재난은 일상의 삶에 대한 도전이자 생존의 문제와 직접적으로 연계되어 있다는 점에서 재난에 대한 정부의 책임 요구가 지속적으로 강조되어 왔다. 정부 역시 재난에 대한 책임과 역할을 위하여 다양한 정책적 노력과 전문성을 강화하기 위한 노력을 지속하여 왔다. 그렇다면 재난에 대한 책임을 모두 정부에 물을 수 있는 것일까? 여기에 대하여 상황을 고려해야 하며, 반드시 정부가 책임이라고 답하기에는 분명 한계가 존재할 것이다. 즉, 재난에 대응하는 과정에서 정부의 노력과 함께 개인적 차원의 관심과 노력 역시 필요하기 때문이다. 따라서 본 연구는 재난관리의 성과가 정부 조직의 책임역량이 증진되는 것과 함께 시민들의 참여도 증진 역시 그 성과로 이해할 수 있을지를 검토하고 실증분석하는데 목적이 있다. 분석을 위하여, 기존 연구들에서 재난관리의 주요한 독립변수로 활용되던 재난경험, 재난위험, 조직특성 등을 주요한 독립변수로 사용하고자 하며, 종속변수는 재난조직의 책임역량과 재난현장에의 시민들의 자원봉사 참여도로 구분하여 설정하였다. 즉, 기존의 재난관리 성과와 대안적 성과로서 시민참여도 증진을 실증분석하고자 하였다. 분석결과, 재난성과는 조직의 내부적 책임역량의 증진과 함께 외부적으로 시민들의 참여를 이끌어 낼 수 있어야 한다. 이러한 시민 참여는 재난관리의 성과로서 정부의 새로운 지표가 될 수 있다. 시민들의 참여는 지역에 대한 재난의 위험 인식이 높을수록 그 참여도가 증진되는 것으로 나타나며, 이는 재난에 대한 대국민 인식개선 및 환경에 대한 위험도 증진의 정책적 노력이 필요함을 의미한다.

The objective of this study is to build a methodology for evaluating intelligent transportation systems (ITS) projects, by selecting measures of effectiveness (MOEs) and developing an approach to collect and process traffic data. While reviewing the existing MOEs and evaluation methodologies for ITS projects, several problems were found, such as the complication in delineating study areas, the absence of standardized evaluation methodologies, and the duplication in selecting MOEs. To tackle these problems, two MOEs capable of directly evaluating traffic conditions were chosen: i.e., average vehicle speed and traffic volume. Both MOEs can not only include all the functions of the existing MOEs, but also be simpler and more objective in evaluating real traffic conditions. The traffic volume can be measured by using either "cordon line" or "all point average" methods. On the other hand, measuring the average vehicle speed depends on site-specific characteristics such as traffic flow states (interrupted or uninterrupted) and traffic conditions (congested or uncongested). The present methodology is easily understandable for anyone and applicable for any ITS project, and is also expected to contribute to building a standardized evaluation system.

The comparison of water balance and nutrient loading from paddy field with different irrigation management were carried out during 1999 ${\sim}$ 2002 at two different sites; one is irrigated with groundwater and the other is irrigated with surface water. For the surface water irrigated paddy field, irrigation was performed continuously during growing season. Whereas, initial irrigation with groundwater was applied during initial growing season, and the ponded water depth was maintained by natural precipitation since initial irrigation. The runoff frequency of groundwater irrigated paddy field was less than that of surface water irrigated paddy field. The nutrient concentration of ponded water was high by fertilization at early cultural periods, so reducing surface drainage during fertilization period can reduce nutrient loading from paddy fields. Amount of irrigation water to surface water irrigated paddy field was higher than to groundwater irrigated paddy field and evapotranspiration was similar because it is influenced by climate. Overall input in and output from paddy field irrigated with goundwater were less than that with surface water. This study indicate that efficient water management can reduce surface drainage outflow, save water, and protect water quality. It might be important BMPs for paddy field.

Artificial intelligence, which is developing as the core of an intelligent information society, is bringing convenience and positive life changes to humans. However, with the development of artificial intelligence, human rights and property are threatened, and ethical problems are increasing, so alternatives are needed accordingly. In this study, the most controversial artificial intelligence ethics problem in the dysfunction of artificial intelligence was aimed at researching and developing artificial intelligence ethical measurement indicators to protect human personality rights and property first under artificial intelligence ethical principles and components. In order to research and develop artificial intelligence ethics measurement indicators, various related literature, focus group interview(FGI), and Delphi surveys were conducted to derive 43 items of ethics measurement indicators. By survey and statistical analysis, 40 items of artificial intelligence ethics measurement indicators were confirmed and proposed through descriptive statistics analysis, reliability analysis, and correlation analysis for ethical measurement indicators. The proposed artificial intelligence ethics measurement indicators can be used for artificial intelligence design, development, education, authentication, operation, and standardization, and can contribute to the development of safe and reliable artificial intelligence.

In this study, on the basis of an analytic hierarchy process (AHP) method and through a questionnaire on subjective preference and importance, various power supply systems were comprehensively compared with multiple decision criteria such as environmental, social, healthy, and economic viewpoints and then overall priority was assessed. When a decision-making problem is modelled by a hierarchy structure, the AHP method is regarded as a useful tool for extracting subjective opinions via the aforementioned questionnaire. Here, the overall preferences were obtained by linearly aggregating weighting vector and preference matrix. The energy systems such as nuclear, coal, and LNG power plants were selected because they took share over 90% of domestic electricity supply in Korea. Furthermore, wind power and photovoltaic solar systems were included as representative renewable energy systems in Korea. According to the results of this demonstration study, the following comprehensive comparison indicators were yielded: 1) weighting factors for 4 types of main criteria as well as for 11 types of sub-criteria; 2) preference valuation for 7 types of energy systems under consideration; 3) overall score for each energy systems.

The purpose of this study is to analyze the actual operation status of the financial performance target management system which is currently operated and to provide improvement plan based on this analysis. For this purpose, I examined the performance management system and performance indicators of the Ministry of Justice, which is one of the criminal justice administration agencies. Although the overall appropriateness of the current performance management system is considered to be somewhat appropriate as a whole, there is a negative perception about the performance measurement method for measuring the achievement of the performance target, and the evaluation of the performance of the performance target is relatively low. In addition, there were many criticisms about the establishment and measurement of the Ministry of Justice's overall performance indicators, such as the tendency to select indicators that are easy to achieve and easy to measure. In order to remedy these problems, it was highly suggested that the importance of indicators should be more emphasized and expanded so as to set up high-performance indicators. Based on the results of this analysis, some suggestions for policy implications and some alternatives for improvement of financial performance target management system were suggested.

용수공급 계획의 수립이나 수자원시설물 운영에서 주어진 목적의 달성여부를 판단하는 기준은 사회적 합의를 바탕으로 한 공개념으로 작용하기 때문에 기준 적용은 매우 신중하게 다루어져야 한다. 이런 기준들은 신규용수공급시설 설계나 기존시설의 경우 이행도를 평가하는 척도가 되며 경제성이나 대안을 결정하는데 이용된다. 또한 이런 기준들은 국가 수자원 정책의 지표가 될 뿐만 아니라 물 공급 서비스를 받는 사람들에게 최소 필요로 하는 물을 어느 수준으로 얼마를 어떻게 공급할 것인가를 약속하는 의미를 갖는다. 이를 위해 우선 검토하여야 할 사항은 용수공급신뢰도 조사를 위한 기본체계를 제공하고 현재 신뢰도가 어떻게 정의되었으며 물 공급관리지표에 맞추어 예상되는 물 수요의 증가를 언제 어떻게 맞출 것인가라는 측면에서 신규시설물을 계획하면서 공급신뢰도에 의한 계획공급량(목표공급량)을 정하였다. 물을 공급받는 수요자는 공급에 대한 신뢰도가 높은 상태를 원하며 자신이 원하는 물을 아무런 장애없이 지속적으로 공급될 수 있는 조건을 전제로 물 공급계약을 체결한다. 이와 같은 신뢰도가 늘 엄격히 지켜지는 것은 아니나 현대 사회에서도 수요와 공급관계에서 지켜져야 할 기준으로 인식되고 있다. 아울러 수자원 기술자들에게 는 최적으로 달성해야할 업무목표가 된다. 그러나 제한된 정보를 이용하여 용수공급의 신뢰도를 정하게 되며 설계치를 초과하는 수문사상의 불확실성 및 수리구조물의 불안정 등으로 물 공급의 위험도는 항시 발생할 수 있다. 또한 인구증가나 새로운 산업입지에 의한 물 수요의 증가는 기존 시설물의 용량을 초과하여 물 공급의 신뢰도를 악화시킬 수 있다. 가장 널리 이용되고 있는 공급신뢰도 개념은 목표한 용수공급량 혹은 수요량을 충족시키느냐 못하느냐의 정도를 발생빈도 확률로 나타내는 것이다. 그러나 신뢰도의 적용에 대한 기준은 국내뿐만 아니라 외국에서도 종종 논란거리가 되고 있다. 또한 한 국가 내에서나 수자원을 개발하는 기관 내에서도 동일 목적의 사업별로 적용기준이 천차만별이다. 본 연구에서는 국내 외 이수안전도에 대한 정의와 적용사례를 분석하고 각각의 기준이나 지표의 장단점을 비교 평가하고자한다. 아울러 도출된 문제점을 바탕으로 개선방향을 제시하고자 하며, 궁극적으로 국내의 이수안전도 기준설정에 대한 종합적 의견을 제시 하고자 한다.

6th Industry reduced agricultural income and rural areas, the economic downturn is going to be activated is attracting attention as an alternative. 6th industry means that the integrated or linked, the manufacture and processing of secondary industry based on primary industry, the distribution and service of tertiary industry. Park Geun-hye government to realize the creative economy in agriculture as an alternative to specifically evaluate the 6th industries and suggests various policy alternatives. In addition, to support the development of models and analysis of best practices, including sleep studies are in progress. However, the 6th Industry management body for performing management level, technical level, the leader in comprehensive evaluation of competencies and indicators on the development of an evaluation study is insufficient. In this regard, the present study performed 6th industry management body for the management level, technical level, the leader competency evaluation indicators to develop a comprehensive evaluation by utilizing AHP method was developed indicators. The results achieved in Korea As different countries and the FTA as cheap agricultural imports increased 6th industry revenues associated with the management body is very likely to be worse. The endless competition to survive in the most important of the strategy for each individual project management body to operate on their own, rather than to strengthen internal capacity by strengthening linkages with other industries, products, and services that promote the sale will be. This also is that you need to improve revenue management body. Thus, all 6th industry management body at the location of their efforts to gain the trust of consumers will require, moreover, for each management body to build cooperation between the various measures will be sought. In addition to the smart era rapidly changing needs of customers, depending on the life cycle of products and services are getting faster and the new consumer is getting more and more tend to find new products. Thus, customers and management body 6th industry changes quickly and accurately predict market trends, and also to market new products and services that further efforts would be needed.

The increase in the area of impervious water due to the recent abnormal weather conditions and rapid urbanization led to a decrease in the amount of low current, resulting in an increase in the amount of surface runoff. Increased surface runoff is causing erosion, destruction of underwater ecosystems, human and property damage in urban areas due to flooding of urban river. The damage has been increasing in Korea recently due to localized heavy rains, typhoons and floods. As a countermeasure, the Busan Metropolitan Government will proceed with the creation of the Eco-Delta City waterfront zone in Busan with the aim of creating a future-oriented waterfront city from 2012 to 2023. Therefore, the current urban river conditions and precipitation data were collected by utilizing SWMM developed by the Environment Protection Agency, and the target basin was selected to simulate flood damage. Measures to reduce flood damage in various cases were proposed using simulated data. It is a method to establish a disaster prevention plan for each case by establishing scenario for measures to reduce flood damage. Considering structural and non-structural measures by performing an analysis of the drainage door with a 30-year frequency of 80 minutes duration, the expansion effect of the drainage pump station is considered to be greater than that of the expansion of the drainage door, and 8 scenarios and corresponding alternatives were planned in combination with the pre-excluding method, which is a non-structural disaster prevention measure. As a result of the evaluation of each alternative, it was determined that 100㎥/s of the pump station expansion and the pre-excluding EL.(-)1.5m were the best alternatives.

This paper introduced Railway Network Design Problem (RNDP) to provide priority decisions on high-speed railway investment scenarios defined by various network segments and train systems. The RNDP optimizes the objective functions of minimize total travel time. Results show that the priority of high-speed railway investment is found to be East-west, West-coast, and South-coast line respectively. An entirely new line built with 400km/h is found to be the best alternative to East-west line. Regarding West-coast and South-coast line, the combined alternative of upgrading Geolla and Kyeonjon line with 200km/h and building a new line with 400km/h and 350km/h for remains of each line is the best.
