최근 중 소규모의 도시개발, 택지개발, 유통단지, 산업단지, 주택단지 조성 등의 단지개발이 급속히 증가하고 있으며, 이에 따라 재해영향평가 및 사전재해영향성 검토도 증가하고 있는 실정이다. 단지개발은 보통 지구지정 또는 기본계획을 수립하여 개발계획 승인을 받고 실시설계를 통하여 실시계획을 승인을 받는 절차를 갖는다. 이에 효율적인 토지이용계획을 위하여 개발계획 승인전에 수십 회의 토지이용을 변경하고 또한 실시계획승인 전에도 토지이용계획은 수회의 변경을 통하여 이루어진다. 이에 재해영향평가 및 사전재해영향성검토를 초기단계에서 수행하는 실무자들은 토지이용계획의 빈번한 변경으로 인하여 저류지 규모 산정에 어려움을 가지고 있다. 단지개발의 토지이용계획 특성상 투수지역이 다소 있는 단지, 투수지역인 공원 녹지, 불투층인 도로 주차장으로 주로 구성된다는 공통점이 있다. 따라서 최근의 심의 완료된 재해영향평가보고서들을 인용, 각 단지개발의 토지이용계획도를 고려한 저류지 홍수조절용량을 산정하는 경험적이고 통계적인 다중회귀모형을 개발하였다. 금회 유도된 다중회귀모형식은 재해영향평가 및 사전재해영향성검토를 수행하는 실무자에게 행정계획단계뿐만 아니라 개발사업단계에서도 신속하게 저류지 규모를 개략 산정하고, 비전문가인 검토자가 신속히 홍수조절용량의 적정성을 검토하는데 매우 효과적으로 사용될 것으로 판단된다.

The geology of Ulleung-Do is dominated by volcanic rocks with low strength and trachytic rocks with high strength but containing vertical joints that yield easily. Consequently, rockfalls along roadcuts are a major geological hazard, with the potential to affect the ring road of Ulleung-Do. In this study, we performed three types of rockfall hazard-risk assessment on the 3-km-long section of the ring road expected to have the highest possibility of rockfall. We used a rockfall ranking sheet in a roadside landslide hazard map, the Slope Stability Inspection Manual for National Highways (Japan), and a rockfall hazard rating system for inspection from the Japan Highway Public Corporation. We also employed the evaluation criteria of 'RHRS' developed by the Federal Highway Administration (FHA). An analysis of roadcuts at 27 sites with regard to geographic and geological conditions resulted in the identification of three classes of rockfall hazard (high, medium, and low). Of note, over 74% of slopes were assessed as high- and medium-class. Finally, a rockfall hazard map of the northeast region of Ulleung-Do was produced based on the evaluation results.

Issues with past practice in seismic hazard analysis of nuclear power plant sites in Korea are addressed. Brief review on both deterministic and probabilistic methods in seismic hazard analysis is given, and most of the continuing discussion is focussed on the probabilistic seismic hazard analysis. Causes of uncertainty are traced on the basis of the cases that the assessment methodology was applied to the nuclear power plant sites. Considerations on the assessment include the role of experts, a representative seismic catalog, seismic source zonation, earthquake ground-motion relationship, and evaluation process. Factors increasing uncertainty in each item are analyzed and some feasible solutions are discussed.

Since the introduction of the converted accident rate in Pre-Qualification(PQ) process in 1992, the safety evaluation system has contributed to a reduction of construction accidents and development of the safety management system in public construction projects. As the comprehensive evaluation method the government plans to introduce includes the indicators 'accident rate' and 'death rate per 10,000 workers', the influences on the safety evaluation in the bidding process would be broader in public sector construction projects. However, the current safety evaluation system is operated by different estimating standards in the bidding process. At this point, a study of improvement on the safety evaluation index is required to review its current conditions and to propose its efficient operating method. Therefore, the purpose of this study is to analyze problems of the current safety evaluation system through the questionnaire survey on the qualified workers in construction safety management and to propose an improvement plan for the problems noticed. Our results suggest the standards of the unified process for the safety evaluation index, the size of construction firms needed for accident rate estimation, and the improvement plan for unreported accidents. The proposed improvement plan enables the reasonable estimation and efficient operation of the safety evaluation index, and further, it would contribute to reducing construction accidents through the activation of voluntary safety management by construction firms.

There are many studies for the economic impact assessment of natural disasters, but there are few for volcanic disasters. Domestic academic research is not under active discussion because of the lack of national and social interest for volcanic eruption. This study investigated the research methodology for the economic impact assessment of natural disasters and discussed whether these can be applied to the economic impact analysis for the Baekdu Mountain volcanic disaster. The main findings are as follows: Firstly, Asia-Pacific region is the most affected by natural disasters and has the largest scale of damage. Asian and American Continent have the most economic damage. Secondly, Considering the types of damage caused by natural disasters and its complex structure, several methodologies that could be possible to estimate economic consequential damages have been compared. When applying each methodology to the Baekdu Mountain volcanic disaster, the scale of damage is likely to be over-estimated or under-estimated because of model-specific features. Thus, estimated values should be compared to each other after calculating the damage results. Thirdly, Japanese academic research on the volcanic disaster will be used as the starting point of the economic impact assessment studies for Baekdu Mountain. Using computer SW such as Hazus which is used in United States and RiskScape from New Zealand is also a good method to predict economic impact of the Baekdu Mountain volcanic disaster.

The high density of population and building; can cause catastrophe in urban areas when natural or artificial disasters break out. The aim of this paper is to assess comprehensive disasters risk of urban areas by Geospatial Information System. For this purpose, we classified disasters risk of urban areas into low categories: flood, fire, building-collapse, and shelter, and then determined factors for hazard risk assessment respectively. The results of hazard assessment can be applied to minimize the demage of disasters in establishing the urban management planning. For more systematic and professional approach the further research is need to consider more disaster assessment factors and join with related experts.

최근의 재해 발생은 하천에 의한 범람, 제방의 붕괴 등에 의한 피해발생보다는 일정지역에 국한적으로 내수배제 불량, 토사유출, 산사태 등으로 인한 피해의 발생이 증가하고 있다. 특히나 도시지역과 신규개발지역을 중심으로 집중호우로 인한 토사유출 등으로 인한 배수로 막힘, 산사태등의 2차적인 피해가 증가하고 있는 추세이다. 2011년의 서울의 우면산 산사태 등과 같은 도시중심에서의 피해와 강원도 등의 신규개발지역에서의 토사로 인해 2차, 3차 피해는 국지적이고 예측이 불가능한 곳에서 발생되고 있다. 이러한 토사유출, 산사태에 의한 예측기법은 최근의 정보기술의 발달로 인해 보다 다양한 방법의 접근들이 시도되고 있으며, 이에 대한 정량적인 평가기법들이 개발되고 적용되고 있다. 본 연구에서는 산지지형의 소규모 개발지의 토사재해의 위험성을 평가하기 위하여 GIS 기술을 이용한 사면의 안정성과 산사태 위험성을 평가하는 대표적인 방법으로 Pack et al. (1998)이 제안한 수리적 무한사면 안정모델과 결합하여 사면안정분석을 위해 개발된 SINMAP을 이용하여 소규모 개발지역의 토석류 해석과 사면의 안정성 검토 그리고 범용토양공식을 이용하여 토사유출량을 산정하여 개발지역내 사면 및 토사재해의 위험성을 평가하였다. GIS를 이용한 지형적 특성에 따른 사면의 위험성과 토사유출량 해석 결과를 이용하여 소규모 개발지역의 토사재해의 위험성을 정량적이고 다각적으로 평가하여 재해발생에 따른 위험성을 노출하고 이에 대한 대책 수립에 도움이 될 것으로 판단된다.

Natural disaster has been hard to prevent the occurrence of itself, thus in order to reduce the economic damages and loss casualties, it is important to be prepared in cases that the disasters should occur in advance. Interest of the related project to prevent various natural disasters has been grown along with an investment in Korea. Along with this movement, when investments related to natural disaster prevention projects were built on, the post evaluation that can verify the ripple effects of those investments on the community should be emerging as an essential task. For evaluating the effects of public investment projects such as natural disaster prevention projects in this study, the related researches would continue through qualitative analyses, for example, cost-benefit analysis. Even the qualitative analysis alone cannot fully explain the effects of those projects, the diverse methods of analyzing and evaluating those effects might not have been presented in those fields. For the post evaluation of natural disaster prevention projects through the qualitative analysis, this study derived subjects that had effects on the post evaluation of natural disaster prevention projects. Also, employing the structural equation modeling (SEM), the causation between post evaluation subjects and the effects of projects were quantitatively analyzed, and the weighting factors of evaluation items were calculated respectively. Based on these results, post evaluation index formula was proposed for the natural disaster prevention projects in Korea.
