This study analyzes the changes in the surface area of each forest cover, based on temperature data analysis and satellite imagery as the basic methods for the impact assessment of climate change on regional units. Furthermore, future changes in the forest cover are predicted using the double exponential smoothing method. The results of the study have shown an overall increase in annual mean temperature in the studied region since 1990, and an especially increased rate in winter and autumn compared to other seasons. The multi-temporal analysis of the changes in the forest cover using satellite images showed a large decrease of coniferous forests, and a continual increase in deciduous forests and mixed forests. Such changes are attributed to the increase in annual mean temperature of the studied regions. The analysis of changes in the surface area of each forest cover using the statistical data displayed similar tendencies as that of the forest cover categorizing results from the satellite images. Accordingly, rapid changes in forest cover following the increase of temperature in the studied regions could be expected. The results of the study of the forest cover surface using the double exponential smoothing method predict a continual decrease in coniferous forests until 2050. On the contrary, deciduous forests and mixed forests are predicted to show continually increasing tendencies. Deciduous forests have been predicted to increase the most in the future. With these results, the data on forest cover can be usefully applied as the main index for climate change. Further qualitative results are expected to be deduced from these data in the future, compared to the analyses of the relationship between tree species of forest and climate factors.

This study assessed the ecological health of border areas using the ecological health index and suggested Indicators for maintaining and promoting ecological values. We analyzed the change trends, pressures, and resilience of ecosystems and services in border areas, and identified their current status and sustainability. The main findings were: (1) ecological assets and ecosystem services in border areas could be compared through ecosystem health assessment; (2) it can be used to set priorities for management and conservation by identifying the relative importance and vulnerability of ecosystems and ecosystem services in each border area; and (3) the index presented in this study can be judged to have explanatory power for the characteristics of border areas and ecosystem health when compared to previous studies. Limitations of this study include the lack of literature and statistical data at the local government level and the resulting limited application of evaluation methods, which limited direct regional comparisons. To overcome the research limitations, further studies are needed, such as establishing ecological information in border areas, mapping and assessment of ecosystem services, and developing and applying assessments that reflect the opinions and participation of various stakeholders. This study was the first attempt to assess the health of ecosystems and ecosystem services in border areas and provided an important baseline for future changes in border areas. In the future, it will be helpful in national and local government policies and ecological assetecosystem management by supplementing insufficient information and presenting clear goals.

The need for designing and implementing integrated policy was further emphasized in tandem with the increase in interest concerning policy coordination and interactions. An active discussion is taking place in the field of innovation policy concerning "integrated innovation policy," which considers innovation along with financial, regional development, social, and environmental policies together in a holistic manner. In Korea since the beginning of the 2000s, there were many attempts at implementing integrated innovation policy through the restructuring of the overall S&T administration system. For the purposes of taking an integrated approach to S&T policies as well as to S&T-related human resources, industrial, and regional development policies, the Roh Administration (February 2003~February 2008) elevated the S&T Minister to the level of Deputy Prime Minister as well as launching the Office of Science, Technology, and Innovation (OSTI) (October 2004 ~ February 2008) under the Ministry of Science and Technology. This study investigates the policy coordination activities of the OSTI from the perspective of policy integration. It deals with the background of the OSTI, its roles and responsibilities, the coordination process, and its achievements and limitations while discussing the important implications for developing effective policy measures with the hope of contributing to the development of theories of integrated innovation policy.

상수도시설은 운영관리 환경, 사용범위, 빈도 등 특성에 따라 수명이 달라지며, 현행 법률에서 일률적으로 정하고 있는 내용연수와 차별된 접근이 필요함에 따라, 시설의 파손, 보수이력 등 관리현황 및 시설의 경시적인 변화 상태를 조사 분석하여 기술적 판단을 토대로 한 수명평가 방안이 필요하다. 따라서 본 연구에서는 국내외 내용연수 적용현황과 시설별 내용연수 산정 방안, 외국의 상수도시설물 관리 방법, 기존 관로 상태평가 기준 수립을 위한 현황 등을 조사하고, 매설 상수관로에 현장조사를 수행하여, 상수관로의 물리적인 파손위험성과 사고이력을 기반으로 경제적 가치 기준에 의한 잔존수명 평가 기법을 개발하였다. 또한 기존 우리 공사의 노후도 기법을 물리적인 노후진척에 따른 상태변화와 실측 데이터를 활용하여 통계적인 분석을 통하여 평가항목은 축소하고, 신뢰도는 제고하였으며, 관 상태평가를 통해서 합리적인 개량계획 수립을 추진할 수 있도록 관상태평가 가이드라인을 개발하였다.

지표를 활용한 대기오염 취약성 평가에서는 지표의 선정과 함께 지표별 가중치 결정이 중요한 문제이다. 본 연구는 전국 249개 시군구를 대상으로 엔트로피 가중치 산정법을 활용하여 오존을 중심으로 한 대기오염 취약성을 평가하고, 엔트로피 가중치 방법론의 활용가능성을 검토하였다. 연구방법은 대기오염 취약성 지표를 선정하고 이들을 표준화하고, 엔트로피를 이용한 가중치를 적용하여 취약성을 평가하는 방식을 활용하였다. 노출 지표는 기상요인과 대기오염요인을 고려하였고, 민감도는 취약대상과 취약환경요인을, 지자체별 적응능력은 지역의 사회 경제적 요소, 보건의료요인, 대기관리 요인을 적용하였다. 취약성 평가 결과는 단순합산의 경우 화성시, 광진구, 김포시, 광주시, 군포시 순으로 취약성이 높게 나타났으며, 취약성-탄력성 지표(VRI) 방식도 단순합산 결과와 유사한 취약지역 공간 분포 패턴을 나타내었다. 본 연구에서 제시한 엔트로피 가중치를 이용한 대기오염 취약성 평가는 자료에 기반한 객관적인 취약성 평가로 불확실성을 동반하는 기후변화와 대기오염 취약성 평가에 활용가치가 높을 것으로 보인다. 또한 취약성 평가결과는 지자체별 특성이 반영된 것으로 세부적인 분석을 통해 지역 맞춤형 정책수립에 활용될 수 있다.

본 연구는 환경부 보호종으로 지정된 삵을 대상으로 다양한 단위면적의 격자 및 유역을 평가단위로 설정하여 충청도 지역의 서식지 적합성 평가를 실시하기 위해 수행되었다. 이미 선진국에서는 GAP(Gap Analysis Program), 서식지 평가절차 및 서식지 적합성지수의 활용 등을 통해 종의 보전을 위한 서식지 평가 및 관리정책을 수립하고 있는 상황이며, 국내에서도 서식지 보전을 위한 다양한 평가방법들이 제안되고 있다. 그러나 국내 연구들은 아직 평가단위에 대한 고찰이 부족하고 분석 결과를 광범위하게 적용하는데도 문제가 있는 실정이다. 본 연구에서는 표고, 경사, 산림, 토지피복, 도로, 하천 등의 환경변수를 로지스틱 회귀모형을 활용하여 유역단위와 격자단위별로 서식지 적합성 평가를 실시하였다. 또한, 이 결과를 비교하여 광역적인 지역단위에 적합한 서식지 적합성 평가단위를 확인하였다. 평가 결과, 종의 발견지점 자체에 대한 환경인자 평가보다 주변의 일정 면적을 함께 고려하여 서식지를 평가하는 것이 적합하며, 그 단위면적은 격자단위 평가의 경우 반경 100m 유역단위의 경우 $1km^2$가 삵의 서식지 적합성을 평가하는데 가장 효과적임을 확인할 수 있었다. 본 연구는 기존의 서식지 보전을 위한 다양한 보전지역 선정 방법을 보완할 수 있는 방법론을 제안하고 있으며, 이 결과는 전국적으로 보전가치가 높은 종의 보전을 위한 관리정책에 활용될 수 있을 것으로 판단된다.

Korea's researchers have recently studied the prediction of forest change, but they have not considered landuse/cover change compared to distribution of forest vegetation. The purpose of our study is to predict forest vegetation based on landuse/cover change on the Korean Peninsula in the 2090's. The methods of this study were Multi-layer perceptrom neural network for Landuse/cover (water, urban, barren, wetland, grass, forest, agriculture) change and Multinomial Logit Model for distribution prediction for forest vegetation (Pinus densiflora, Quercus Spp., Alpine Plants, Evergreen Broad-Leaved Plants). The classification accuracy of landuse/cover change on the Korean Peninsula was 71.3%. Urban areas expanded with large cities as the central, but forest and agriculture area contracted by 6%. The distribution model of forest vegetation has 63.6% prediction accuracy. Pinus densiflora and evergreen broad-leaved plants increased but Quercus Spp. and alpine plants decreased from the model. Finally, the results of forest vegetation based on landuse/cover change increased Pinus densiflora to 38.9% and evergreen broad-leaved plants to 70% when it is compared to the current climate. But Quercus Spp. decreased 10.2% and alpine plants disappeared almost completely for most of the Korean Peninsula. These results were difficult to make a distinction between the increase of Pinus densiflora and the decrease of Quercus Spp. because of they both inhabit a similar environment on the Korean Peninsula.
