Recently, as a part of measures against large-scale natural disasters in Korea, disaster prevention matters are strengthened in urban planning. With the introduction of the disaster vulnerability analysis system, plans for disaster prevention are being reinforced in urban planning. However, there are many problems to be solved at the stage of operation and practical application of the law. When disasters occur, we are focusing on response and recovery plans. Therefore, it is not enough to construct a comprehensive disaster prevention system to prevent disasters in advance. The established disaster prevention plan is difficult to plan management centered on disaster prevention due to factors such as economic efficiency, convenience, and comfort. This study is a basic study for supporting disaster prevention mitigation plan. For this purpose, the analysis of the actual situation of disaster prevention plan at home and abroad and improvement plan were derived. ased on these improvement plans, we have developed a method to apply the element technology of urban design to the test bed to reduce sediment disaster. The test bed was investigated and examined in the disaster hazard area of Busan and Seongnam city. And the defense technology is applied to the selected site, and the basis of the disaster prevention plan and design is proposed. If the proven techniques are reflected from the urban planning stage, it will be possible to contribute to the mitigation of sediment disaster caused by the city.

최근 기후변화, 도시화 등으로 도시의 환경이 변화함에 따라 재난이 빈번하게 일어나고 있다. 이와 같은 상황을 해결하기 위해 건축가 및 도시계획가에 의해 다양한 도시방재디자인이 실험되고 있고, 새로운 방재기법인 리질리언스 개념이 적용되고 있다. 이에 따라 본 연구는 건축가 및 도시계획가에 의해 제시된 도시방재디자인 사례를 연구대상으로 하여 도시방재디자인의 유형과 리질리언스 특성을 분석하였고, 더 나아가 지속가능한 도시방재디자인을 위한 방향을 제안하였다.

This study aims to contribute to urban policy for more effective disaster prevention, as abnormal natural disasters are becoming more frequent. Up to now, the urban plan for disaster prevention in Korea merely includes basic principles and necessities of measures as an early stage. Furthermore, there are difficulties to make specific programs because the legal system, technical instruments, and financial supports are not sufficient. Therefore, this study figures out problems in the current plan related to urban prevention after analyzing the legal system and practices. Resulting from case studies in developed countries, the study draws significant implications, as follows: enhancing legally binding force; improving the procedures for the programs; establising technical infrastructure. It first suggests a way for the urban policy for disaster prevention by considering our local features comprehensively. It then defines the roles of central, local governemnts and research institutions, and the procedure for urban disaster prevention planning building on the individual roles. This study concludes that an emphasis should be placed on institutional tools necessary to publish technical guideline and establish the system so that urban planners more easily access to disaster risk information.

Resilience has been suggested as a new paradigm of disaster management which reduces losses against disasters under the uncertain circumstances. The purpose of this study is to define the concept and to set up the objectives of urban resilience for disaster management. The common concept and components of resilience were analyzed by examining recent studies on resilience. The resilience was defined as "a capacity of physical and social urban elements adapting and recovering against disaster for better condition" and the five objectives of resilience - Robustness, Redundancy, Resourcefulness, Rapidity, and Regional Competency - were derived from the review of literatures. The major disasters and accidents were analyzed focused on those objectives. The concept and objectives of urban resilience could be used as a guidance for disaster prevention planning and disaster management processes.

In recent years, the scale of damage from disasters such as earthquakes and large-scale fires and floods that are occurring in Korea is increasing. Accordingly, interest in urban disaster prevention that combines living infrastructure such as roads and parks is boosting, and it is urgent to prepare measures to reduce the damage scale of local cities. The purpose of this study is to derive implications for disaster prevention measures in areas where disaster prevention safety of local cities is weak through examples of disaster prevention safety of local cities in case of disaster. To this end, this study analyzed the regional characteristics, current status, and disaster prevention problems of regional cities in Japan, and selected disaster-vulnerable areas, and considered the distance relationship between disaster prevention bases through road network analysis. In addition, road closure simulation using ArcGIS Network Analyst was conducted to analyze disaster prevention safety in the area. As a result, the situation of the village which has a high possibility of isolation by natural disasters was grasped in advance. Through this, the suburbs confirmed the necessity of supplementing the disaster prevention function through transportation maintenance such as forest roads, and it was found that the city needs to prepare a risk management system. Furthermore, this study suggests the need for research on areas with a high possibility of isolation, especially in areas where disaster prevention functions are weak in local cities in case of disaster, and shows countermeasures for disaster prevention measures and resident education.

도시화 산업화로 인하여 도시지역과 농촌지역은 인구 구조, 경제수준, 인프라 등 다양한 특성에서 차이를 보이고 있으나 재난안전대책은 이러한 특성을 반영하지 못하고 있는 것이 현실이다. 다양한 분야에서 도시와 농촌을 비교하는 연구를 실시하고 있지만 재난 및 안전 관리적 측면에서의 연구는 전무한 실정이다. 지역의 재난관리 대책 마련 시 도시지역 및 농촌지역 주민들의 자신이 살고 있는 지역에 대한 체감안전도, 문제점, 요구사항이 무엇인지 파악하고 주민의견을 반영할 필요가 있다. 따라서 본 연구에서는 도시와 농촌의 재난환경에 관한 이론적 검토를 실시하였으며, 도시지역과 농촌지역에 거주하고 있는 주민들의 재난안전에 대한 인식을 알아보기 위해 주민들에게 재난안전(비구조적요소, 구조적요소, 인적요소, 환경적요소)에 관한 의식조사를 실시하였다. 또한 이를 토대로 향후 도시지역과 농촌지역의 재난관리계획 수립 시 반영사항을 도출하였다.

In this study, among the W-S-R(Wiper-Signal-Rainfall) relationship methods used to produce sensor-based rain information in real time, we sought to produce actual rainfall information by applying machine learning techniques to account for the effects of wiper operation. To this end, we used the gradient descent and threshold map methods for pre-processing the cumulative value of the difference before and after wiper operation by utilizing four sensitive channels for optical sensors which collected rain sensor data produced by five rain conditions in indoor artificial rainfall experiments. These methods produced rainfall information by calculating the average value of the threshold according to the rainfall conditions and channels, creating a threshold map corresponding to the 4 (channel) × 5 (considering rainfall information) grid and applying Optima Rainfall Intensity among the big data processing techniques. To verify these proposed results, the application was evaluated by comparing rainfall observations.

홍수는 도시가 피할 수 없는 자연재해이다. 홍수 재해는 도시의 경제와 안전, 그리고 지속발전을 심각하게 저해한다. 수변 공간에 대한 개발과 건설 과정에서 기본적인 방재시설의 건축을 통해 홍수의 경제적 피해를 줄이고자 막대한 자본을 투입하더라도 이를 완전히 피할 수는 없으며. 재해 발생 후 도시의 재건 비용은 방재(防災)시설의 건설비용보다 훨씬 많은 비용을 필요로 한다. 최근 몇 년간 도시재건 등에 있어 탄성(resilient)이론은 학계의 광범위한 토론과 주목을 불러일으키며 도시의 문제해결에 관한 주제가 되어왔다. 즉, 탄성의 방재개념을 이론과 경험적 요소를 토대로 어떻게 실천으로 전환시켜야 하는지가 도시방재가 마주하고 있는 현실적 문제이다. 본 논문은 도시의 수변(공간) 완충지역(홍수 취약지역)여 관한 이론 문헌과 도시의 실천 사례연구를 통해 탄성 방재이론인 5R 요소를 명확화하고, 이에 따른 상세 대책을 제시하고자 한다. 또한, 도시의 수변완충지역을 중심으로 탄성 방재이론 요소의 도시수변(공간)계획에서의 실행 가능성을 강조하는 동시에 다음과 같은 두 가지 문제를 해결하고자 한다. 첫째, 방재계획수단을 이용해 도시수변토지의 개별 효용과 수변완충지역의 방재기능 간의 갈등을 완화하는 것과 둘째, 수변완충지역이 탄성 방재계획을 통해 방재 측면에서 홍수가 수반하는 문제에 최대한 대응할 수 있게 하는 것이다.
