When an age of low growth and population decline, population migration plays an important role in spatial structure of region. There have been many researches on migration and regional spatial structure. The purpose of this study is to examine the changes of Gwangju and Jeonnam region’s spatial structure and central area using social network analysis methods. For analysis it was used that population and migration data and passenger OD(Origin and Destination) travel data released by Statistics Korea and Korea Transport Database(KTDB). Using Gephi 0.8.2, migration and passenger OD networks were visualized, and this describe network flow and density. The results of the network centrality analysis show that the most populated village is not always network center though population mass is an important factor of central places. The average eigenvector centrality of 2010 migration is the lowest during 2005-2015, and it means few regions have high centralities. When comparing migration and travel networks, travel data is more effective than migration data in determining the central location considering spatial functions.

The objective of this study is to accurately understand the spatial distribution characteristics of the main production area for the three vegetable crops such as Chinese cabbage, radish, and hot pepper. We applied the 8 landscape indices such as TA, NP, PD, LPI, LSI, PLADJ, COHESION, and CONNECT to 35 cities and counties using FRAGSTATS. In the case of main production area for Chinese cabbage, six cities and counties in Gangwon province were revealed as a relatively high degree of aggregation by cultivation parcels than other area. In addition, Gangneung city and Hongcheon county have been analyzed to be the most aggregated area in the case of radish and hot pepper, respectively. In the future, the spatial analysis method used in this study would be helpful to develop an effective regional plan of the main production area.

본 연구는 강건성 지수와 불확실성 분석기법을 활용하여 기후변화 취약성 평가과정에서 발생하는 불확실성을 정량화하였다. 본 연구는 우리나 라의 6개 광역시(부산, 대구, 인천, 광주, 대전, 울산)를 대상으로 다기준 의사결정기법 중 하나인 TOPSIS 기법을 이용하여 용수공급 취약성 순위를 산정하였다. 강건성 지수는 두 대상 도시의 순위가 가중치의 변화로 인해 순위역전현상이 발생할 수 있는 가능성을 정량화하고 불확실성 분석 기법 은 두 도시 사이에 순위역전이 발생할 수 있는 가중치의 최소 변화량을 산정한다. 그 결과 인천과 대구는 용수공급 측면에서 취약한 것으로 나타났 으며, 대구와 부산은 용수공급 취약성에 민감한 것으로 나타났다. 따라서 대구는 다른 대안에 비해 상대적으로 용수공급이 취약한 지역으로 나타났 으나, 취약성에 민감하기 때문에 기후변화 적응대책 수립 및 시행을 통해 취약성이 크게 향상될 수 있을 것으로 판단된다. 본 연구는 기후변화와 용 수공급 측면에서의 적응전략을 계획하고 수립하는데 있어서 우선적으로 고려해야하는 방향을 제안하는 데 사용될 수 있다.

Aging phenomenon is an important issue in Korea national policy. This aging phenomenon depends on the social and environmental characteristics of regions. Also aging phenomenon and regional characteristics have spatial dependency. The purpose of this study is to discover the spatial changes in aging population rate and to find local factors of regional aging phenomenon considering spatial autocorrelation. For spatial analysis of ageing phenomenon, local Moran’s I and Geographically Weighted Regression (GWR) were applied. As the results, the most significant changes of aging phenomenon appeared between 2000 and 2005, and most of hot-spot regions (aged regions) were distributed in Jullanam-do and Jullabuk-do. The results of GWR (R-square: 0.681) shows that total fertility rate, the number of doctor per 1,000 people and forest area rate have positive relation with aging population rate, but the number of private academy per 1,000 people has negative relation.

As a result of analysis based on the observed data for BOD, COD and TOC in order to manage non-biodegradable organics in the Geumho River, COD/BOD ratio was analyzed as the occupying predominance proportion. In this study, the classification(changes in water quality measurement : increase, equal, decrease) and measurement of BOD and COD were analyzed for trends over the past 10 years from 2005 to 2014 in the Geumho River. The Geumho River is expected to need non-biodegradable organics management because BOD was found to be reduced 61.1% and COD was found to be increased 50%. As a result of the analysis of land use, the Geumho-A is a unit watershed area of 921.13 km2, which is the most common area that is occupied by forests. The Geumho-B is a unit watershed area of 436.8 km2, which is the area that is highest occupied by agriculture and grass of 24.84%. The Geumho-C is a unit watershed area of 704.56 km2 accounted for 40.29% of the entire watershed, which is the area that is occupied by urban of 15.12%. Load of non-biodegradable organics, which is not easy biodegradable according to the discharge, appeared to be increased because flow coefficient of COD and TOC at the Geumho-B were estimated larger than 1 value. The management of non-point sources of agricultural land is required because the Geumho-B watershed area occupied by the high proportion of agriculture and field. In this segment it showed to increase the organics that biodegradation is difficult because the ratio of BOD and TOC was decreased rapidly from GR7 to GR8. Thus, countermeasures will be required for this.

본 연구에서는 소규모 지역 내 6대의 우량계를 설치하여 조밀한 강우 관측망을 구축하고 이를 통하여 소규모 지역에 대한 강우의 공간적 변화도를 분석하고자 하였다. 우량계는 60 m의 동일한 간격으로 배치하고 총 54일간의 강우관측을 수행하였다. 이물질로 인하여 오작동을 일으킨 1대 우량계를 제외한 5대의 우량계를 이용하여 50일간 강수량에 대하여 분석을 수행하였다. 각 우량계에 관측된 50일간 누적강우량 비교결과 최대 약 38.5 mm의 차이를 나타내었다. 상관성 분석결 과 일강우량은 소규모 지역에서 매우 일관성 있는 자료를 보여주고 있으나 1시간 이하 강우량 시계열에서는 차이가 있음을 확인할 수 있었다. 공간 변화도 분석결과, 변동계수가 시강우량의 경우 최대 약 224%, 일강우량의 경우 최대 약 91%로 나타났다. 면적강우량 불확실성 분석결과, 4대의 우량계만을 이용할 경우 대상지역에 대하여 95% 이상의 정확도를 확보하 기 힘든 것으로 나타났다. 향후 보다 신뢰성 있는 홍수예보와 효율적인 유역관리를 위해서는 점 중심의 강우 관측이 아닌 면적 강우 관측방법의 개발이 필요할 것으로 생각된다.

The relationship between urban spatial structures and GHG-AP integrated emissions was investigated by statistically analyzing those from 25 administrative districts of Seoul. Urban spatial structures, of which data were obtained from Seoul statistics yearbook, were classified into five categories of city development, residence, environment, traffic and economy. They were further classified into 10 components of local area, population, number of households, residential area, forest area, park area, registered vehicles, road area, number of businesses and total local taxes. GHG-AP integrated emissions were estimated based on IPCC(intergovernmental panel on climate change) 2006 guidelines, guideline for government greenhouse inventories, EPA AP-42(compilation of air pollutant emission factors) and preliminary studies. The result of statistical analysis indicated that GHG-AP integrated emissions were significantly correlated with urban spatial structures. The correlation analysis results showed that registered vehicles for GHG (r=0.803, p<0.01), forest area for AP (r=0.996, p<0.01), and park area for AP (r=0.889, p<0.01) were highly significant. From the factor analysis, three groups such as city and traffic categories, economy category and environment category were identified to be the governing factors controlling GHG-AP emissions. The multiple regression analysis also represented that the most influencing factors on GHG-AP emissions were categories of traffic and environment. 25 administrative districts of Seoul were clustered into six groups, of which each has similar characteristics of urban spatial structures and GHG-AP integrated emissions.

The purpose of this study is to show the relation of the change between spacial structure and social conditions of rural area. The spacial structure change of Asan city was analyzed using Space Syntax, and multiple regression analysis (dependent variables: connectivity, global integration, local integration / independent variables: population, household, farm population, farm population of 65years old and over, farm household, part-time farm households, cultivated land) was accomplished. As th result, that the increase of connectivity is related to the increase of population and farm population of 65years old and over and the decrease of farm population, and the increase of local integration is related to the increase of farm population of 65years old and over was showed. However, that global integration is not related to change of social conditions was proved.

The purpose of this study is to estimate regional economic effects of spatial diffusion of wildfire using Cobb-Douglas production function of agriculture and forestry. The analysis is applied to Gangwon and Gyeongbuk provinces where are the most damaged of wildfire in Korea. The damaged areas are derived from multiplied by the occurrence probability of wildfire and diffusion areas of wildfire for micro-spatial unit level with ArcGIS techniques. The models of wildfire provides that the spatial diffusion of wildfire increases with the rising of highest temperature and average wind speed. Through the production function, value added of Agriculture and Forest sectors get damaged where the Cos-converted slope aspect of mountains are toward the South. The production model provides reductions of regional value added by increasing damaged areas of wildfire. It reveals that the most damaged region is Andong city in Gyeongbuk province, where value added loss is 1.25 billion Won, which is about 0.72% of total value added in agriculture and forestry of the city. As a view of policy makers, it needs to be considered to establish prevention policies against wildfires because regional economic losses from wildfire are depending on geographical conditions and performances of the major industry related to wildfire's diffusion such as agriculture or tourism sector according to the result of analysis.

본 연구에서는 지역특성(위도, 경도, 고도)과 기후학적 특성(연최대강우량)을 계층적 Bayesian 모형안에서 연계하여 공간적 분석이 가능한 지역빈도해석 모형을 개발하였다. 기존 지역빈도해석은 강수지점의 지리적/지형적 특성을 반영한 해석이 어려운 단점이 있으며, 지점을 기준으로 해석된 확률강수량을 유역면적강우량으로 변환 시 불확실성이 큰 단점이 있다. 이에 본 연구에서는 계층적 Bayesian 기법을 이용하여 지역특성 및 기후학적 특성이 고려된 Gumbel 확률분포형의 매개변수를 추정하였으며, 이들 매개변수들을 공간적으로 보간하여 한강유역내 모든 지점에 대해서 확률강수량을 추정할 수 있도록 하였다. 결과적으로 기존 L-모멘트 방법과 유사한 결과를 확인할 수 있었으며 확률강수량의 불확실성 정량화와 더불어 지리적/지형적 영향을 고려한 해석이 가능하였다.

다목적댐 저수지는 여름철에 발생하는 성층현상이 발생하고 가을철에는 성층화된 저수지의 밀도 차로 인한 전도현상이 일어나게 된다. 이러한 현상은 저수지의 시공간적 수온분포의 변화에 의하여 발생하며, 이를 정확히 모의하고 예측하기 위해서는 수온에 작용하는 관련 매개변수의 작용특성을 명확히 파악할 필요가 있다. 이에 본 연구에서는 합천댐 저수지를 대상으로 횡방향 평균 2차원 저수지 수리 수질 해석모형인 CE-QUAL-W2를 적용하여 저수지내 발생하는 수온성층, 탁수의 거동 및 수질을 예측하기 위해 선행되어야 할 수온모의를 통해 합천댐 저수지에 적합한 수온 매개변수 산정에 대한 연구를 진행하였다. 특히 모델에서 합천댐 수온모의와 관련된 매개변수 중 바람차폐계수(WSC), 복사열계수(BETA), 빛소멸계수(EXH2O), 바닥 열교환계수(CBHE)의 민감도 분석을 수행하였다. 첫 번째로, 민감도가 높은 기간을 확인한 결과 WSC, BETA, EXH2O는 공통적으로 4∼9월, CBHE는 8∼11월로 나타났다. 두 번째로, 매개변수가 영향을 미치는 수심대를 확인한 결과 BETA는 0∼9 m, EXH2O는 8∼14 m 구간으로, 수표면과 가까운 표층과 수온약층, CBHE는 바닥에서부터 12 m 구간으로 심층구간에서 영향이 나타났다. 마지막으로 연단위 혹은 각월에서의 최적매개변수를 적용한 결과 WSC와 CBHE 매개변수는 모의온도의 편차가 그다지 크지 않았으나, BETA와 EXH2O의 경우 연단위와 월단위 최적매개변수 적용 시 모의수온편차가 각각 월평균 0.20℃와 0.51℃로 다소 큰 값을 보이고 있으며, 특히 수온이 최대로 상승하는 5∼8월 중에는 0.4℃와 1.09℃의 편차를 보여 월단위 매개변수사용의 필요성이 뚜렷이 확인되었다. 이는 현재 저수지수질모형의 검보정에서 입력요구조건에 따라 혹은 관행적으로 사용되고 있는 연단위 매개변수의 사용에 있어서 월단위로의 개선이 필요한 부분으로 사료된다.

강우는수문순환에서중요한요소중에하나로시·공간적변동성이크므로정확한공간강우장의파악이요구된다. 열대강우 관측 위성(Tropical Rainfall Monitoring Mission, TRMM)에서 제공하는 3B43 월 누적 강우량 자료는 25 km의 공간해상도를 갖고 있어 공간 강우장의 정확성을 높이기 위해 상세화 기법을 적용하여 1km의 공간 해상도로 생성하였다.Terra 위성에 탑재된 MODIS (Moderate Resolution Imaging Spectroradiometers) 센서가 제공하는 정규식생지수(Normalized Difference Vegetation Index, NDVI) (공간해상도1km)와강우자료의관계성을회귀식으로나타냈고상세화기법에 적용하였다. 이에 따른 결과를 지점과 위성 강우 자료와의 차이를 통해 보정하는 방법인 GDA (Geographical Difference Analysis)와 지점과 위성 강우 자료와의 비율로 편차를 보정하는 GRA (Geographical Ratio Analysis) 상세화기법을사용하여공간강우장을나타내었다. 우리나라의공간강우장결과를지점자료를기준으로비교검증을실시하였다.그결과GDA 상세화기법의경우가2009년(Bias=4.26mm, RMSE=172.16 mm, MAE=141.95 mm, IOA=0.64), 2011년(Bias=17.21 mm, RMSE=253.43 mm, MAE=310.56 mm, IOA=0.62)으로가장잘맞는것으로나타났다. 이를바탕으로우리나라의공간 강우장을 1 km의 공간 해상도로 파악할 수 있었으며, 더 나아가 지점의 수를 늘려 보정을 정밀하게 하거나, 강우레이더 자료를 가지고 상세화 기법을 적용한다면 더욱 정확한 공간 강우장을 파악할 수 있을 것이다.

A lot of rural development projects have been planned and implemented for revitalizing rural areas in South Korea. However, it is not easy to properly evaluate and quantitatively analyze project outcomes. For this reason only selected regions have been evaluated for rural projects by government agencies. In this study, we analyzed the purpose and the contents of the Rural Village Development Project (RVDP) and Green Tourism Village Project (GTVP) to find indicators for evaluating results of rural projects using logistic regression analysis. Outputs of this study show that RVDPs increase regional population and GTVPs positively affect the sales of agricultural products. We also estimated the spatial distribution of project effects through spatial autocorrelation analysis and local-spatial autocorrelation analysis. Results show that the Moran's I values for the proportion of farmers with avocational jobs, product sales changes, and population growth in Jeol-La province are positive and the biggest one is population growth. Especially, key areas of agricultural product sales are widely distributed.

The aim of the research was to analyze a correlation between rural villages and a space of amenity resources in order to provide objective basic data for rural renewal planning in the future. 15 villages were selected to analyze amenity resources. A Space Syntax Method(SSM) was used to analyze a spacial structure of each village and location characteristics of amenity resources. Finally, Statistical Package for the Social Sciences(SPSS) was used for a cluster analysis. The results of spacial analysis showed that the MeanDepth of rural villages was 4.482 and Global Integration Value(GInteg) was 0.956. Relatively, a depth was lower and GInteg was higher, compared to other villages. Rural villages were easily recognized and accessible by outsiders, compared to mountain and fishing villages. In the case of rural villages, the MeanDepth of amenity resources was low and GInteg was high in the results of cluster analysis using a nonhierachical method. Results indicated that an access was easy and amenity resources were closely located each other. However, the deviation of each village was great in mountain villages. This research suggests that an effective maintenance of road network for improving accessibility would be given priority in an undeveloped farming and fishing villages' renewal. Especially, using a spacial analysis in village renewal planning process can improve accessibility and maximize an utilization of public facilities and amenity resources.

본 연구에서는 용담댐 상류, 천천 시험유역을 대상으로 분포형 수문모형을 이용하여 강우의 공간분포 특성에 의한 유역에서의 침식 및 퇴적양상을 분석하고, 유출 및 유사량 모의결과에 미치는 영향을 분석하였다. 일반적으로 강우의 공간적 분포를 묘사하기 위해 사용되는 지점 강우 내삽기법(Thiessen Polygon: TP, Inverse Distance Weighting: IDW, Kriging) 및 레이더 강우 합성기법(Gauge-Radar ratio: GR, Conditional Merging: CM)을 이용하여 태풍으로 인한 3개의 집중호우 사상기간동안의 강우장을 생성한 후 각 기법들에 의해 생성된 강우장의 양적, 공간적 특성을 평가하였다. 또한, 각 기법별로 생성된 공간분포형 강우를 분포형 수문모형에 적용하여 강우의 공간분포에 따른 유역에서의 강우-유사-유출 분석 및 유역에서의 침식 및 퇴적양상을 비교·분석하였다. 그 결과, 지상 우량계를 이용한 내삽기법의 경우 유사한 우량주상도 및 수문응답을 나타내었으며, 원시 레이더 자료 및 GR기법에 의한 결과는 각각 과소, 과대산정된 반면 CM기법은 레이더 강우의 공간적 특성을 유지하면서 양적으로도 개선된 결과를 보여주었다. 또한 양적으로 유사한 강우장임에도 불구하고, 각 기법에 의한 강우장의 공간적 특성으로 인하여 대상유역내 침식 및 퇴적양상은 매우 상이하게 나타났다.
