사전재해영향성 평가제도는 재해예방 차원의 절차로서 종합적이고 체계적인 개발사업을 위하여 2005년 도입되었다. 하지만, '재해영향성평가 실무지침'에 의거 제주도의 경우 수문지질학적 특성으로 인하여 홍수량 산정에 따른 확률강우량 산정 시 일반적인 방법이 아닌 고도반영이 가능한 등우선에 의한 확률강우량을 산정하도록 명시되어 있다. 하지만, 제주도의 경우 한라산을 중심으로 형성되어 있지만, 한라산 정상에 무인기상관측소(AWS)가 3개소 위치하고 있으며, 타 시·도 보다 기상관측소가 조밀하게 위치하고 있어 소규모 사업지구의 홍수량 산정 시 우량관측소의 확률강우량을 적용하거나 Thiessen 방법을 이용하는 일반적인 방법을 적용하더라도 무리가 없을것으로 판단된다. 따라서, 본 연구는 제주도내 사전재해영향성 평가제도의 적용에 있어 일반적인 우량관측소의 확률강우량과 등우선에의한 지점확률강우량을 비교·분석하여 그에 따른 영향성을 검토하였다.

Background: The evaluation of skyshine distribution, release of airborne radioactive nuclides, and soil activation and groundwater migration were required for radiological assessment of the impact on the environment surrounding In-Flight (IF)-system facility of the RAON (Rare isotope Accelerator complex for ON-line experiment) accelerator complex. Materials and Methods: Monte Carlo simulation by MCNPX code was used for evaluation of skyshine and activation analysis for air and soil. The concentration model was applied in the estimation of the groundwater migration of radionuclides in soil. Results and Discussion: The skyshine dose rates at 1 km from the facility were evaluated as 1.62 × 10^-3 μSv·hr^-1. The annual releases of ³H and ¹⁴C were calculated as 9.62 × 10^-5 mg and 1.19 × 10^-1 mg, respectively. The concentrations of ³H and ²²Na in drinking water were estimated as 1.22 × 10^-1 Bq·cm^-3 and 8.25 × 10^-3 Bq·cm^-3, respectively. Conclusion: Radiological assessment of environmental impact on the IF-facility of RAON was performed through evaluation of skyshine dose distribution, evaluation of annual emission of long-lived radionuclides in the air and estimation of soil activation and groundwater migration of radionuclides. As a result, much lower exposure than the limit value for the public, 1 mSv·yr^-1, is expected during operation of the IF-facility.

이 연구에서는 급경사지 재해영향평가 기준의 적절성을 확인하기 위해 급경사지 관리시스템(NDMS: National Disaster Management System)에 구축된 정보를 분석하였다. 분석결과를 통해 재해영향평가의 신뢰성을 저하하는 요인이 될 수 있는 평가방법 및 제도의 문제점을 도출하였다. 재해위험도 평가지표의 경우 콘크리트 옹벽, 보강토 옹벽, 석축 등 다양한 형태의 옹벽을 평가할 수 있도록 평가지표를 개선할 필요가 있는 것으로 나타났다. 또한 전도 배부름과 백태에 대한 평가 점수가 동일한 것은 평가의 신뢰도를 하락시키는 요인일 될 수 있어 가중치에 대한 개선이 필요한 것으로 나타났다. 사회적 영향도 평가지표의 경우 철도, 국립공원, 저수지 등 급경사지 주변 환경의 특성을 고려한 평가방법의 세분화가 필요한 것으로 나타났다. 급경사지 평가 제도의 경우 효율적인 관리를 위한 급경사지 시 종점 분할 기준이 마련되어야 하며 정비사업 전 후의 효과를 반영할 수 있도록 보호 보강 공법에 대한 평가지표를 보완하고 정비사업 후 재해영향평가를 실시할 필요가 있다. 본 연구에서 제시한 문제점은 현재의 평가 기준을 운영하는 과정에서 도출된 사항으로 향후 이를 반영하여 재해영향평가를 보완할 필요가 있는 것으로 판단된다.

As the procedure of the close examination of disaster impact at the initial stage of the beginning of development plans, the newly extablished Pre Disaster Impact Assessment Review Deliberation (PDIARD) system which have been introduced through the revision of the Natural Disaster Countermeasure Act-revised at August, 2005 is enforced for the purpose of the disaster prevention which caused during a development projects. From that time down to this day, the PDIARD system have been reviewed about 6,000 cases totally. However, the current the PDIARD system at the uppermost limit in the aspect of every Acts and operational problems is in need of sustaining supplementation at the present situation. To cope with this operational remedy related to the PDIARD system, this study deals in 3 major concerns. First, it is required to fix a criterion in detail because of a wide range of the subject plans of deliberation. Second, there is some ambiguity according to the area or length of the subjected administrative and development plans. So it should be excepted of the targeted plans which has few probability in disaster potential or vulnerability. Finally, the subjected plans need to be added as to the continuous urbanization and industrialization and the enactment or revision of the Acts related. This study focuses on the investigation and analysis to find out the improvement way about the main problem pending of the PDIARD system, consequently suggests a effective remedy and new categories, including future directions and detailed plans for operation.

자연재해의 경제적 영향평가에 대한 연구는 많으나 화산재해의 영향평가에 대한 연구는 상대적으로 매우 적다. 국내의 경우, 화산 폭발에 대한 국가적, 사회적 관심 부족으로 화산재해 영향평가에 대한 학계 연구도 매우 부족하다. 이러한 연구실정을 고려하여, 본 연구는 자연재해의 경제적 영향평가 연구방법론을 조사하고 향후 예상되는 백두산 화산재해에의 적용 가능성을 검토하였다. 본 연구의 주요 내용과 결과를 요약하면 다음과 같다. 첫째, 자연재해 및 화산재해에 대해 조사한 결과, 아시아지역에서 자연재해 피해규모가 가장 컸고 아시아와 아메리카 대륙의 경제적 피해가 가장 많았던 것으로 나타났다. 둘째, 최근 30년 사이에 화산분화가 매우 빈번했던 일본에서 화산재해로 인한 피해연구가 활발했던 반면, 화산분화가 드문 한국과 중국에서는 화산재해의 경제적 영향에 대한 연구가 매우 희소하다. 셋째, 자연재해에 의한 피해 유형 및 복합 피해구조에 대하여 살펴보았고, 그 중에서 정량적인 분석이 가능하다고 생각되는 경제적 간접피해를 추정할 수 있는 몇 가지 방법들을 비교 검토해 보았다. 각 방법론을 백두산 화산재해에 적용하는 경우, 모형 고유의 특징 때문에 피해규모가 과대 추정되거나 혹은 과소 추정될 가능성이 있으므로 계산된 피해결과는 사후적인 비교 검토가 필요하다. 마지막으로 일본의 화산재해에 관한 학술적 연구를 백두산 화산폭발의 경제적 영향 평가 연구의 출발점으로 활용할 수도 있겠지만, 미국에서 사용되는 Hazus나 뉴질랜드에서 사용되는 RiskScape와 같은 컴퓨터 SW를 활용하거나 개발하여 백두산 화산재해의 경제적 영향을 예측하는 것도 좋은 방법이라고 생각된다.

In an effort to analyze the impact of climate change, Gangwon provincial forest was divided into three sectors; forest ecology, forest disaster, and forest productivity and analysis of their current status from 2000 to 2009 and vulnerability assessment by climate change has been carried in this study. In case of vulnerability assessment, except for the forest ecology, forest disaster (forest fires and forest pests) and forest productivity sectors were analyzed in current status, the year of 2020, and 2050. It turned out that vulnerability of forest fires in the field of disaster would become worse and forest pests also would make more impact even though there is some variation in different areas. In case of the vulnerability of forest productivity there would be not a big difference in the future compared with current vulnerability. Systematic research on the sensitivity index used for vulnerability assessment is necessary since vulnerability assessment result greatly depends on the use of climate exposure index and adaptive capacity index.

This study applies the concept of climate change vulnerability assessment in order to suggest climate change adaptation effects in a quantitative manner, given that previous studies have hitherto rely on qualitative assessment, as climate change adaptive policies are currently being implemented by local governments of Korea. The vulnerability assessment tool used in this study is VESTAP ("Vulnerability assESsment Tool to build a climate change Adaptation Plan"), which was developed by the Korea Adaptation Center for Climate Change (KACCC), and applied to gauge the vulnerability of pine trees to diseases and pests within Chungcheongnam-do. The climate change adaptation project for vulnerability improvement was assessed only in terms of forest disaster prevention and change in regional climate change vulnerabilities within 16 regions of Chungcheongnam-do as the result of 2016 Climate Change Adaptation Project (Forest Disaster Prevention Project). As a result, it was observed that climate change adaptive capacity has improved according to change in the area of forestland with disaster prevention, and the vulnerability indicator decreased, confirming the impact of the climate change adaptation (forest disaster prevention) project. Also, analysis of regional climate change adaptation project scales and change in vulnerabilities allowed us to determine the regional propriety of climate change adaptation (forest disaster prevention) projects launched in 2016.

The purpose of this study is to identify the problems of environmental impact assessment(EIA) and to suggest new EIA technology. The problems of EIA in Korea can be summarized as follows. First, the EIA does not reflect the impact of policy, plan and program on environment. Second, the project EIA does not consider the cumulative impacts such as additive impacts, synergistic impacts, threshold/saturation impacts, induced and indirect impacts, time-crowded impacts, and space-crowded impacts. Third, the EIA techniques in Korea are not standardized. Finally, the present EIA suggests only alternatives to reduce adverse impacts. To solve above-mentioned problems, the development of new EIA technology is essential. First, the new EIA technology should be developed toward pollution prevention technology and comprehensive and integrated environmental management technology. Second, new fields of EIA for pollution prevention contain strategic environmental assessment, cumulative impacts assessment, socio-economic impact assessment, cyber EIA and EIA technology necessary after the reunification of Korean Peninsula. Third, EIA technology for integrated environmental management contains the development of integated environment assessment system and the development of packaged EIA technology. The EIA technology for integrated environmental assessment system contains (1) development of integrated impact assessment technology combining air/water quality model, GIS and remote sensing, (2) integrated impact assessment of EIA, traffic impact assessment, population impact assessment and disaster impact assessment. (3) development of integrated technology combining risk assessment and EIA (4) development of integrated technology of life cycle assessment and EIA, (5) development of integrated technology of spatial planning and EIA, (6) EIA technology for biodiversity towards sustainable development, (7) mathematical model and GIS based location decision techniques, and (8) environmental monitoring and audit. Furthermore, there are some fields which need packaged EIA technology. In case of dam development, urban or industrial complex development, tourist development, landfill or combustion facilities construction, electric power plant development, development of port, road/rail/air port, is necessary the standardized and packaged EIA technology which considers the common characteristics of the same kind of development project.
