  • The disaster prevention information system is to comprehensively support information collection, processing, search and supply in disaster counter measuring activities, as well as to manage information mainly related to natural disasters unilaterally. Building an optimal system in adequate consideration of features and demands in terms of disaster prevention is requested. Suitable infrastructure that can support information technology (IT) in various aspects should be established in order to utilize IT effectively in disaster prevention information. In addition. accuracy, reliability and efficiency as a disaster prevention information system should be equipped with. In this study, a basic framework for the establishment of disaster prevention information system is presented.

  • 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.

  • In the field of forest disaster prevention, drones are expected to save higher human resources than the existing manpower has, and produce high-efficiency results over time. However, operational limitations brought by short flight times have brought the environment of limited use of the various capabilities of the drone, and the existing development systems operating the multi-drone are mainly for performance purpose, so it is a difficult to use for forest disaster prevention. The purpose of this paper is to design the concept based on multi-drone operation procedure through analysis of mission of ground control system for forest disaster prevention.

  • Reasonable disaster prevention signs play an important role in guiding evacuation. Through the field investigation on disaster prevention signs in shelters and surrounding areas in Beijing, some problems were found in the using of sign system. Based on the principle of integrated design, evacuation and rescue requirements, it is necesssary to make further study on aspects such as, design of function, systematic consideration, humanization design, as well as the internationalization using. This paper presents an evaluation index system for disaster prevention signs. Such a system is very important for strengthening the independent guiding function of sign systems and improving evacuation efficiency. An effective connection could be realized between the internal environment of buildings, evacuation routes, and emergencey shelters.

  • This study attempted to develop and suggest a more appropriate method for the determination of event mean concentration (EMC) and pollutant removal efficiency of a stormwater best management practice (BMP) considering rainfall. The stormwater runoff and hydrologic data gathered from 22 storm events during a 28-month monitoring period on a swirl and filtration type of BMP were used to evaluate the developed methods. Based on the findings, the modified EMC method resulted in lower (average) values than the overall EMC, although the differences were not significant (P>0.05). By comparison, the developed 'Rainfall Occurrence Ratio' (ROR) method was most significantly correlated (r=0.967 to 988, P<0.009) with the other existing removal efficiency determination methods such as the 'Efficiency Ratio' (ER), 'Summation of Loads' (SOL) and 'Regression of Loads' (ROL) methods. In addition, the ROR method gave the highest efficiency values, with no significant differences with any of the pollutant parameters, unlike the other three methods. These results were obtained because the ROR method integrated both pollutant loading and rainfall, which are not considered by the other three methods. Therefore, this study proved the suitability of the modified EMC and ROR methods for application in other BMP monitoring studies.

  • Recently, industrial accidents rate has been gradually decreasing due to the development of safety management methods, but until now, the accident rate in the construction sector is higher than other industries. Large-scale construction sites are operating systematic safety systems to reduce industrial accidents. However, small and medium sized construction sites do not have systematic safety system and lack safety management ability, so that disaster is not reduced compared with large scale construction site. As a result, disaster prevention technology instruction system has been implemented to reduce the disasters of small and medium scale construction sites. However, in the case of a small construction site less than 2 billion won, there is little decrease in the accident rate, and in some cases, the accident rate increases. After the technical guidance system has been implemented, it is necessary to identify the performance and problems of implementation and to improve its effectiveness. In this study, we suggest the improvement plan to improve the efficiency of the technical guidance system by analyzing the problems and actual conditions of technical guidance operation in small and medium sized construction work sites.

  • 재난 발생시 보다 안전하고 효율적인 도로 운영을 위해서는 사전에 대피 및 방재경로 등의 지정과 더불어 재난 발생시 상황 변환에 따른 신호운영 방안이 정의되어 있어야 한다. 특히 재난 발생시 운영자의 대응이 지체된다면 도로 이용자의 안전을 확보할 수 없을 뿐만 아니라 막대한 사회적 손실을 입게 되므로 교통방재시스템의 설계방향에 대한 연구가 이루어져야 할 것이다. 본 연구에서는 풍수해로 인한 피해가 잦은 청주시를 대상으로 교통방재시스템을 설계하고, 도로 이용자의 안전을 위해 대피 및 방재경로를 새롭게 정의하였으며, 경로의 효용성을 높이기 위해 신호운영방안을 영향권별로 정의하여 그에 대한 효과를 분석하였다. 본 연구에서 정의한 신호운영을 적용하여 분석한 결과 평상시와 유사한 교통흐름을 나타내었으며, 재난 발생시 재난에 대한 정보를 도로 이용자들에게 최대한 빠르게 전달하고, 상황에 적절한 신호운영을 실시한다면 이용자들의 안전을 확보할 수 있을 것으로 판단되었다.

  • 인적 물적 자원이 고밀화된 도시에서 발생하는 홍수 또는 침수는 도시의 기능을 마비시키거나 많은 인명피해를 발생시킬 수 있다. 본 연구에서는 유역을 재해발생지점, 재해직접영향권, 재해간접영향권으로 구분하고 각 구역별로 적합한 재해저감 도시설계기법을 적용하여 피해를 최소화하고자 한다. 이를 위해서는 우선적으로 도시설계기법을 적용하여 시뮬레이션하고 정량적으로 효과를 검증할 필요가 있다. 따라서 본 논문에서는 국내에서 사용되고 있는 도시유출모형을 활용하여 재해저감 도시설계기법의 효과 분석을 위한 적용성을 검토하였다. 검토결과로써 효과분석을 위한 FFC2Q모형, XP-SWMM과 같은 집중형 모형의 한계점을 제시하였다.

  • The number of landslides has increased since the 2000s due to the increased frequency of heavy rainfall caused by abnormal weather. A variety of debris flow prevention facilities have been installed as a countermeasure against this problem. However, it is not easy to evaluate the efficiency of debris flow prevention structures except for the structures with constant volume such as the erosion dam, because the other structures are limited to be reproduced in simulation program for debris flow. Therefore, the methods by which the debris flow prevention structures were modeled were proposed, and the efficiency of four prevention structures installed in Baekyang Mt. in Busan was evaluated with UDS, which accuracy had been verified, using these methods. The initial amount of debris flow was determined based on landslide which occurred in 2014, and specifications of the complex retaining walls around the settlements were measured and applied modeling for terrain. The numerical results showed that the efficiency of debris flow prevention structures could be quantitatively presented. Among the debris flow prevention structures installed in Baekyang Mt., prevention structure of barrier type for debris flow was the most efficiency and debris flow prevention device was the lowest efficiency when the only depth of debris was evaluated. It seems that this study is meaningful to propose the methods which were used to model the debris flow prevention structures that could not be reproduced in most 2D debris flow numerical analysis programs. If precise verification of the presented methods is carried out, it will be possible to provide clear criteria for the efficiency evaluation method of disaster prevention structures.
