  • 자연재해로부터 야기되는 피해를 줄이고 자연재해저감활동을 전개하기 위해서는 기상정보와 재해자료에 근거한 정확한 예보와 방재활동이 요구된다. 또한 사전방재활동을 위해서는 방재기상정보로의 처리가 필요하다. 이를 위하여 본 연구에서는 행정자치부에서 발행하는 통계연보와 재해연보, 중앙재해대책본부에서 발행한 최근 10년간 자연재해 피해 현황, 기상청에서 발행한 기상연보를 이용하였다. 이들 4가지 자료를 이용하여 자연재해의 원인과 피해요소, 발생빈도, 취약지역 등을 분석하였는데, 이들 자료는 피해내역과 기상현상에 대한 분류 및 용어가 일치하지 않으므로, 재해의 종류와 피해액을 비교 분석한 결과, 기상재해 원인과 피해 요소, 피해액, 피해지역 등과 같은 재해 변수를 선정하고, 재해연보를 이용하여 database를 구축하였다. 이렇게 구축된 database는 앞으로 자연재해 저감계획과 risk model을 개발하고 자연재해를 평가하는데 유용하게 쓰일 수 있다.

  • 최근 수년간 급증하고 있는 자연재해로 인해 사회적 관심과 함께 연구개발 투자도 지속적으로 증가하고 있다. 하지만, 현재 자연재난분야 연구개발 사업의 성과관리는 기술개발활동 건수, 특허 건수, 논문 건수 등 정량화하기 용이한 지표위주로 구성되어 있으며, 단순히 지표들을 집계하는 차원에 머물고 있어, 해당 분야의 연구개발 특성과 효과를 적절하게 반영하지 못하고 있으며, 연구개발사업의 성과관리 차원에서도 한계를 가지고 있다. 본 연구는 자연재난분야 연구개발 사업에 있어 보다 효율적인 연구개발 사업관리와 연구개발의 당위성 확보를 위한 성과지표 및 성과평가체계를 개발하는 데에 목적이 있다. 이를 위하여 개발한 기존 연구개발 사업 성과지표를 고찰하고 자연재난분야 연구개발 사업이 갖는 고유의 사회 경제적 파급효과의 특성을 고려하여 성과측정지표를 도출하였으며, 이러한 성과지표를 활용하여 사업유형별 특성을 고려한 성과평가체계를 개발하였다. 개발된 성과평가체계의 활용을 통해서 자연재난분야 연구개발 사업에 있어 획일적인 성과평가체계를 개선하고, 사업 특성에 적합한 측정지표항목을 선별적으로 선택하여 평가가 가능한 유연하고, 신뢰성 있는 성과관리가 이루어질 수 있을 것으로 기대된다.

  • In order to reduce the amount of damage from natural disasters, we needs prevention meteorological database classified into the cause of disaster, damage elements etc. For this, we have analyzed four data, such as Statistical yearbook of calamities issued by the National Emergency Management Agency and Annual Climatological Report issued by the Korea Meteorological Administration and Recently 10 years for natural disaster damage and Statistics Yearbook from the Ministry of Government Administration and Human affairs. Through the analysis of disaster data, we have selected input variables, such as causes and elements, occurrence frequencies, vulnerable areas of natural disaster, etc. In order to reduce damage from natural disaster, the prevention activities and forecasting based on meteorological parameters and damage datas are required. In addition, it is necessary to process meteorological information for disaster prevention activities. Through these procedure, we have established the foundation of database about natural disasters. This database will be used to assess the natural disasters and build risk model and natural disasters mitigation plan.

  • Natural vibration of truss cable structures is analyzed based upon the general structural analysis software ANSYS, energy variational method and Rayleigh method, the calculated results of three methods are compared, from which the characteristics of free-vibration are obtained. Moreover, vertical seismic response analysis of truss cable structures is carried out via time-history method. Introducing three natural earthquake waves calculated the results including time-history curve of vertical maximal displacement, time-history curve of maximal internal force. Variation curve of maximal displacement of node along span, and variation curve of maximal internal force of member along span are presented. The results show the formulas of frequencies for truss cable structures obtained by energy variational method are of high accuracy. Furthermore, the maximal displacement and the maximal internal force occur near the 1/5 span point. These provide convenient and simple design method for practical engineering.

  • Over the past few decades, the impact of natural, manmade and natech (natural hazard triggering technological disasters) disasters has been devastating, affecting over 4.4 billion people. In spite of recent technological advances, the increasing frequency and intensity of natural disasters and the escalation of manmade threats is presenting a number of challenges that warrant immediate attention. This paper explores the integration of drones or Unmanned Aerial Vehicles (UAV's) into infrastructure monitoring and post-disaster assessment. Through reviewing some of the recent disasters, effectiveness of utilizing UAV's in different stages of disaster life cycle is demonstrated and needed steps for successful integration of UAV's in infrastructure monitoring, hazard mitigation and post-incident assessment applications are discussed. In addition, some of the challenges associated with implementing UAV's in disaster monitoring, together with research needs to overcome associated knowledge gaps, is presented.

  • This study aims to find out a state of the damages and vulnerable areas from natural disasters in the Korean peninsula using the prevention meteorological database information made by Park(2007b). Through the correlation analysis between damage elements and total property losses, we investigate the damages of public facilities, which have high correlation coefficient, and the cause of disasters and want to propose the basic information to set up the disaster prevention measures in advance. As a result, because most of the total property losses is the damages of public facilities, we can reduce the damages of natural disasters if we can predict the damages of public facilities or carry out the prevention activities in advance. The most vulnerable area for the natural disasters are Cangwon-do and Gyeongsangnam-do provinces. The vulnerable areas for the damages of public facilities by typhoon are Daegu metropolitan city, Cangwon-do, and Gyeongsangbuk-do provinces. These vulnerable areas will take place more frequently due to the climate change including Gyeongsangnam-do province so that we need to set up the disaster prevention measures and natural disaster mitigation plan. Also, we think that it has effect on reducing the damages of natural disasters to predict the damage scale and strongly perform the prevention activities in advance according to typhoon track and intensity.

  • This study aimed to design the accelerated life testing (ALT) of concrete, which stimulating the special natural environment maximumly. Its evaluation indexes, such as dynamic elastic modulus, mass and ultrasonic velocity were measured, and the variation of relative mass and relative dynamic elastic modulus of concrete were studied. Meanwhile, the microanalysis method was used. Moreover, an exploratory application of the stochastic approach, the Weibull distribution and the lognormal distribution, were made to assess the durability of concrete structures. The results show that the ALT for simulating natural environment is more close to the service process of concrete structure under actual conditions; The relative dynamic elastic modulus can be used as the dominant durability evaluation parameters, because it is more sensitive to the environmental factors compared with the relative quality evaluation parameters; In the course of the concrete deterioration, the destruction of the salt freezing cycle is the dominant factor, supplemented by other factors; Both of those two stochastic approaches can be used to evaluate the reliability of concrete specimens under the condition of ALT; By comparison, The lognormal distribution method is better to describe the reliability process.

  • Two types of responses to climate change exist. First is climate mitigation which includes efforts of reducing CO2 and GHG emissions. Second response is climate adaptation process which is establishing climate resilience in the supply chain. The two are inherently different since mitigation strategy focus on eliminating the source of climate change and is long term in nature but adaptation strategy is moderating the impact of potential or current climate change. In order to embed climate resilience in the supply chain, mitigation strategies and adaption strategies must be implemented simultaneously. Corporation's adaptation to climate change related natural disaster can be seen as a response that includes mitigation and adaptation strategies simultaneously. A comprehensive climate change resilience supply chain approach has to be developed. This paper illustrated guidelines and adaptation process framework businesses can utilize in order to build climate resilience. Screening process before the actual assessment of risk was introduced as well as the whole adaptation process of establishing information system and strengthening climate-related operational flexibility.
