  • 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.

  • 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.

  • 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.

  • The objective of this study is to introduce the urban utility concept that combines urban growth and urban disasters in the aspect of a conceptual theory. While many studies focused on the dollar amount damaged from a disaster, it requires adding not just building damages or human body losses but also the quality of life satisfaction. An issue in measuring the quality of life satisfaction needs to introduce a proper mode quantifying it. This study introduces the urban utility change in measuring the negative impacts of a disaster on urban life, which has been rarely investigated. To identify urban utility, urban flooding that is a cross-sectoral agenda and important to both developed and developing countries was adopted to respond to its increased frequency and damages, encouraging governments to focus on flood control policies. By combining a literature review on urban utility and urban growth, this study defined the urban utility concept as a net benefit of a resident with earnings subtracting housing and commuting costs. The theoretical study also explained that urban utility and its components dynamically change as per urban growth and disasters that even reversely affect urban growth. Because the urban utility can be one of the useful indices to appreciate the relationship between a disaster and urban growth, it is highly expected to apply for similar disaster impacts on urban areas, including COVID-19 and various global warming issues.

  • 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.

  • 본 연구는 도시화가 도시의 자연재해에 어떤 영향을 미쳤는지에 대해 패널모형을 통해 실증분석하고 있다. 연구의 문제의식은 도시화가 지역의 환경변화를 통해 도시의 기후변화에 따른 자연재해 취약성을 더욱 높일 수 있음에 착안한다. 본 연구의 분석틀은 도시재해 피해에 영향을 미치는 요소들에 대한 개념화에서 출발한다. 도시화는 토지이용과 인구밀도 두 가지 관점에서 조작적으로 정의되었으며 도시재해 피해를 늘리는 중요변수들을 위주로 모델링되었다. 본 연구의 분석결과는 도시화가 도시의 자연재해 피해를 반드시 증가시키지는 않으며 오히려 적절히 관리될 경우 피해를 줄일 수도 있는 것으로 나타났다. 도시화는 자연재해 피해를 늘리기도 하지만 동시에 저감시킬 수 있는 가능성을 가지고 있음을 확인하였으며, 이를 토대로 향후 기후변화에 대응하는 바람직한 적응정책(adaptation policy)의 방향을 제시하고 있다.

  • 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.

  • The earthquake input is required when the soil-structure interaction (SSI) analysis is performed by the direct finite element method. In this paper, the earthquake is considered as the obliquely incident plane body wave arising from the truncated linearly elastic layered half space. An earthquake input method is developed for the time-domain three-dimensional SSI analysis. It consists of a new site response analysis method for free field and the viscous-spring artificial boundary condition for scattered field. The proposed earthquake input method can be implemented in the process of building finite element model of commercial software. It can result in the highly accurate solution by using a relatively small SSI model. The initial condition is considered for the nonlinear SSI analysis. The Daikai subway station is analyzed as an example. The effectiveness of the proposed earthquake input method is verified. The effect of the obliquely incident earthquake is studied.
