This study attempted to determine the division indexes which could identify mountain villages region at the eup and myeon administrative districts. The division indexes were selected first, by choosing variables which could show the characteristics of mountain villages region and permanent indicators, second, by verifying through the statistical analysis. According to the analysis, the division indexes of mountain villages region were the percentage of forest area and the mean altitude of villages; the percentage of forest area was more than 70% and the mean altitude of village was more than 250 meters in each administrative districts, or the mean altitude of village was over 400 meters. Mountain villages region divided by the division indexes was composed of 32.2% of total national area and 3.6% of total national population, respectively. Furthermore, the mountain region villages had the characteristics of severer depopulation and poorer agricultural base condition than those of the other regions.

The developed composite index has limits to estimate and predict economic status due to economic pattern change and the response change of explanatory variables. A higher precedence individual indicators should be selected to predict the future accurately. In this study, effectiveness of Jeju Island precedence indicators consists of constituents in the area, the consumer price index, services production index, mining and manufacturing production index. The average temperature of Seogwipo and credit card purchase amount is reviewed as an economic turning point consideration and time lag correlation analysis with real data. In addition, we suggest the proper reference cycle in Jeju composite precedence index and evaluate the configuration in leading indicators for Jeju by comparing national economic indicators. Based on the derived results, the current problems of Jeju Island precedence indicators will be illustrated and the improvement methods to estimate a regional composite index will be suggested.

This study is a basic study to evaluate the ecological environment of Changwon City. The study site was 6 ecotourism districts in Changwon-si, and the ecotourism index was evaluated through direct visits and interviews with the person in charge through preliminary research and various literature data from June to July 2021. There are six ecotourism indicators: climate crisis, air quality improvement, water conservation, natural coexistence, citizen participation, and tourism resource management. When looking at the scores for the six ecotourism areas in Changwon, it received the highest score in the areas of natural coexistence and air quality improvement. However, the ecoregion received the lowest score in the water resource conservation category, indicating that the water resource conservation as a whole was weak. Next, tourism resource management, climate crisis, and citizen participation are at the same level in all regions. As a result of the evaluation through the low-carbon ecotourism index, the Changwon City low-carbon ecotourism certification system should first be operated as a measure to revitalize the ecotourism region. It is necessary to prepare a low-carbon ecotourism level for Changwon City. Second, it is very important to guide and promote ecotourism areas to revitalize ecotourism areas. Lastly, to operate a sustainable eco-environment area, it is necessary to operate using local governance above all else.

This study was performed to identify neighborhood deprivation indicators associated with health and to test the contextual effects of those indicators on individual health. This study calculated SMR based on Dong district and see the differences of prediction across deprivation index and indicators. Then, a multi-level analysis using HGLM was conducted to test the contextual effect of neighborhood depreivation indicators on health after controlling for demographic and socioeconomic status of individuals. The results showed that regional SMR had strong correlations with land price, education, welfare recipients, female household proportion in Dong district but failed to show the correlation with individual health and neighborhood deprivation. Individual health was only associated with individual level of demographic and socioeconomic status. That is, spatial dispersion of illness is understood as the distribution of social classes in terms of socioeconomic status of individuals, not the contextual aspects of community.

본 연구의 수행을 위해 23개의 JERS-1 SAR 와 두 개의 ERS-2 SAR 자료를 이용하였다. 비록 ERA-2 pair로부터 생성된 인터훼로그램(interferogram)은 70일의 짧은 간격 자료임에도 불구하고 수목, 구름, 눈 등에 의한 temporal decorrelation 과 낮은 관측각에 의한 layover등에 의해 인터훼로그램의 질이 좋지 않아 분석에 이용될 수 없었다. 반면에 JERS-1 SAR(L 밴드) 자료간의 pair는 매우 긴 시간 간격에도 불구하고 비교적 높은 긴밀도를 가지고 있어, 본 연구지역과 같이 지표 변화률이 매우 느릴 것으로 예상되는 지역에서 장기간의 변화를 관측하기에는 적합하다. 우리는 altitude of ambiguities가 매우 큰 3개의 인터훼로그램과 2-pass, 3-pass DInSAR 방법을 사용하여 1992년 9월과 1998년 10월 까지 약 6년 동안의 지표변위를 관측하였다. 다양한 시간 간격(704, 1056, 1100, 1118, 1232, 2112 days) 별로의 차분 인터훼로그램(differential interferogram)의 결과와 그들간의 상호관계성를 이용하여 연구지역의 지표변위를 분석하였다. 2-pass, 3-pass, 그리고 altitude of ambiguity가 큰 인터훼로그램으로부터 관측된 결과 모두, 백두산 산체와 남서쪽에 위치하고 있는 홍두산을 중심으로 수십km에 걸쳐서 지표가 상승하고 있음을 지시한다. 계산된 지표상승률은 1년에 약 9cm 정도이다.

Observation of land surface temperature in industrial areas is problematic, as it is not possible to construct a network of weather stations with sufficiently high density and continuous operation in such zones. Multiphase remote sensing data that cover a wide area and take a short time to process can enable the user to precisely and continuously measure the current and changing land surface temperatures in a certain region. Jeollanam-Do in South Korea is undergoing rapid industrialization, with the establishment of a number of industrial complexes, such as the Gwangyang Steelworks, Yeosu Industrial Complex, Yulchon Industrial complex, and Daebul Industrial Complex. To look into the properties of industrial complex's temperature, this study uses the thermal band of Landsat 7 ETM+ images acquired under thermal infrared wavelengths in order to calculate and compare the surface temperatures of the four above-named industrial complexes. From this, it is possible to obtain the basic information about industrial complex for environmental and natural resource management, which will aid industrial complex planners in developing methods of addressing environmental problems.

The existing researches related to the fog have focused on mainly the fog itself and its spatial variation. This study defined the hazardous fog as the fog with visibility under 500 m which caused the severe dangerous situation on roads and might cause traffic accident due to insufficient visibility. This study aimed to develop the hazardous fog index which quantified the degree of danger and included frequency of fog, visibility and its duration. We applied the index to 3 years weather station data in Korea and the results showed the distribution of the hazardous fog and their priority in terms of safety management. This was the first study that introduced the fog index in Korea and that quantified the degree of hazardous fog. These application results were useful for identifying the dangerous area due to hazardous fog and contributing to ensure the safety of eventual road users and road authorities.

This study aims to identify the factors that contribute to the regional innovative capacity and to analyze the effects on the regional economic development including newly-established corporation and job creation. The results are as follows. First, as a result of factor analysis, the 14 variables were grouped into 3 factors, i.e. innovative input, infrastructure, and linkage. Second, the panel models were developed using the above factor scores and economic performance variables such as the number of newly-established corporation and employees. As a result, innovative capacity factors positively contributed to the newlyestablished corporation and job creation. The innovative input was the most influential factor determining the regional economic performance, followed by linkage and infrastructure. This study suggests several policy implications for the reinforcement of innovative capacity and regional competitiveness.

최근 물부족 현상은 심각한 사회ㆍ환경적 문제가 되고 있으며, 이에 대처하기 위한 방안의 하나로 지표수-지하수 연계이용이 대두되고 있다. 지표수와 지하수 연계이용은 수자원을 수문학적 순환 사이클의 관점에서 파악하고 상호보완적 이용을 도모하는 통합적인 방안이다 본 연구는 계획 수립단계에서 연계이용의 가능성, 시급성 측면에서 최적의 대상지역을 선정하기 위한 체계적인 적지분석 방법론을 제시한다. 이를 위해 복잡한 의사결정 문제를 계층적으로 나누어 분석하는 기법(AHP)이 적용되었다. AHP를 통해 분석에 필요한 의사결정인자를 도출하였고, 그 상대적 중요도를 정량화 하였다. 입지인자의 중요도를 바탕으로 가상의 지역에 대한 각 측면의 적합도를 산정하였고, 비중을 달리함으로써 얻어지는 다양한 대안에 대하여 최종적인 적합도가 산정되었다. 이러한 방법론에 의거한 분석자료는 최종적인 의사결정을 위한 기초정보를 제공할 것이며, 지역 간 연계이용 우선순위를 평가하는데도 활용될 수 있을 것이다.

본 연구는 무주군 적상산 부근에 위치하는 소유역에서 지표수와 인접한 천층 지하수의 안정동위원소 조성의 시공간적 변화를 규명하기 위해서 시행되었다. 조사는 2001년 8월과 10월, 2002년 4월 세 차례에 걸쳐 수행되었다. 각 계절에 따라 지표수와 지하수의 안정동위원소 조성이 비슷하게 나타나는 것은 이 지역 지표수와 지하수사이에는 배수와 충진이 지속적으로 생기고 있음을 암시한다. 조사지역의 안정동위원소 조성은 북쪽에 위치하는 한강의 안정동위원소 조성보다는 무거우며, 남쪽에 위치하는 섬진강의 안정동위원소 조성보다는 가벼운 위도효과를 잘 나타내고 있다. 또한 시료를 채취한 가장 높은 지점과 가장 낮은 지점의 고도차가 400m인 작은 소유 역에서도 계절의 변화와 관계없이 안정동위원소의 고도효과는 잘 나타나고 있다. 선행된 연구에서 우리나라 강우가 우량효과를 반영하는 결과를 나타내는 것과 같이 강우의 영향을 직접 받는 8월 지표수의 안정동위원소 조성은 10월과 4월보다 더 가벼운 조성을 나타내고 있다.
