In this study, we tried to predict the change of future land-cover and relationships between land-cover change and geo-spatial information in the Gongju area by using fuzzy logic operation. Quantitative evaluation of prediction models was carried out using a prediction rate curve using. Based on the analysis of correlations between the geo-spatial information and land-cover change, the class with the highest correlation was extracted. Fuzzy operations were used to predict land-cover change and determine the land-cover prediction maps that were the most suitable. It was predicted that in urban areas, the urban expansion of old and new towns would occur centering on the Gem-river, and that urbanization of areas along the interchange and national roads would also expand. Among agricultural areas, areas adjacent to national roads connected to small tributaries of the Gem-river and neighboring areas would likely experience changes. Most of the forest areas are located in southeast and from this result we can guess why the wide chestnut-tree cultivation complex is located in these areas and the possibility of forest damage is very high. As a result of validation using the prediction rate curve, it was indicated that among fuzzy operators, the maximum fuzzy operator was the most suitable for analyzing land-cover change in urban and agricultural areas. Other fuzzy operators resulted in the similar prediction capabilities. However, in the prediction rate curve of integrated models for land-cover prediction in the forest areas, most fuzzy operators resulted in poorer prediction capabilities. Thus, it is necessary to apply new thematic maps or prediction models in connection with the effective prediction of changes in the forest areas.

Rural Traditional Theme Villages are one of the village-based businesses, which obtains excellent results. However, it also has brought negative results such as splits in locals due to income disparity, and ill-advised development which does not consider surrounding potential resources, etc. So, this study analyzes several problems of Rural Traditional Theme Villages, and proposes how Rural Traditional Theme Villages can be revitalized by benchmarking other successful cases. First, it is important to pursue differentiation of operating programs for Rural Traditional Theme Villages. Second, it is possible to give weight to elements which show efficiently rural atmosphere to enhance images of Rural Traditional Theme Villages. Third, expanding budget support and securing a new route for budget are definitely needed to cultivate self-growth capability of villages. Fourth, it is necessary to apply experts and facilities of local-based universities, cooperate with relevant organizations, and nurture local leaders by various means such as study in/visits to advanced regions at home and abroad and experts training. Localgovernment should be in charge of nurturing talented people. Fifth, it is necessary to reinvigorate rural economy by networking each Rural Traditional Theme Village, providing a wide range of information on diversified villages to people in cities, and promoting consumption. Moreover, securing immovable customers is important through networking city-rural exchange with city consumers and other organizations, and sisterhood relationship, membership businesses and events. As mentioned above, it is expected that Rural Traditional Theme Villages will be able to be developed continuously as a model for rural revitalization, which is stagnant, by expanding city-rural interchange.

Despite numerous efforts on reducing road-kill worldwide, the collisions have been occurring continuously. Many factors are affecting road-kill occurrences and the effect is various by species. We investigated Hydropotes inermis argyropus road-kill characteristics on the national highway. We examined 9,099 H. i. argyropus road-kill points with distance to the gaps on road (interchange and intersection) and distance to six natural land-cover types as explanatory variables. We also examined the number of road-kill occurrences according to temporal variation using chi-square test with 9,658 events. In general, H. i. argyropus road-kill location tended to occur close to the gaps on road, agricultural lands and forests. The average distance from road-kill to the gap was 694.7 m and 78.6% of the collisions were occurred within 1 km from the gaps. In addition, Kruskal-Wallis test showed the distance between road-kill points and each land cover and the gaps was significantly different. The temporal analyses showed that the differences of the H. i. argyropus road-kill frequency are significant in both month and season. Our results implies H. i. argyropus road-kill location tended to occur close to the gaps on road, agricultural lands and forests in general, especially during May and June, according to their seasonal behavior. Thus, we suggest there is a need of concentrated management on the roads with specific characteristics for both wildlife and human safety.

The purpose of this study is to investigate how the hollowization in rural villages which causes marginal villages appears in Korean rural villages and whether the hollowization has relation with decrease and aging of population or not. For achieving the research objective, survey was carried out focused on Geumsan-gun. As a result, it confirmed that rural out-migration and rural decline especially in 'people', 'land(economic situation)' and 'community' have being progressed. Also variance analysis and regression analysis were executed with using the number of population and the ratio of people over 65 as dependent variables and using each survey contents(variables) as independent variables. The results of analysis showed that the ratio of people over 65(+), the income level per household(-), the rate of fallow lands(+), the number of empty houses(+), programs for urban-rural interchange(+), and the implementing public projects(+), etc. have a relation with the number of population(-) and the number of population(-), the income level per household(-), the rate of fallow lands(+), the number of empty houses(+), activities of communities(+), and the implementing public projects(+), etc. have a relation with the ratio of people over 65(+) (+: increase, -: decrease). So the hollowization in people', 'land(economic situation)' and 'community' has direct relation with decrease and aging of population in rural areas.

The purpose of this study is to analyze the impact of land-use and population change in rural area by new expressway. Chungbu expressway constructed in 1987, going through the south area of Kyunggi province from Seoul, was selected as a case expressway, and also 2 cities and 18 subdivisions of county in its surrounding area, as a case study area. To analyze the change characteristics before and after the construction, land-use maps of 1986 and 1996 were collected, including the census data for the years in cities and counties yearbooks. Remote sensing technology was applied to classify the land-use maps with six types of land use. Geographic information system was also used for spatial analysis, such as the land-use and accessibility changes. A 5 km buffer zone from interchange of the expressway showed about two times increase of urbanized built-up area than a 5 km buffer zone from the expressway. Accessibility from Seoul and cities was improved in most areas, which is accessing to Seoul through existing Youngdong expressway. Ten rural areas showed increased population with accessibility of average 52 minutes to Seoul and 19 minutes to cities, while eight areas showed decreased population with average 73 minutes to Seoul and 35 minutes to cities. This shows that the threshold value, which is time distance to Seoul and cities for population increase or decrease, one and half hours, respectively. Urbanized area was increased in most areas, even in population decrease areas, so this indicates that there are thinning rural areas, increasing urbanized area while decreasing population.

본 연구는 공주지역의 지표변화를 분석하기 위해 우도비 기반의 베이지안 예측모델을 이용하여 지리공간 정보와 지표변화와의 연관성 및 미래의 지표변화를 탐지하였다. 지표변화 지역은 위성사진을 토지피복분류 한 후 선분류 후비교법을 이용하여 변화지역을 추출하였다. 지표변화와 관련이 있는 지리공간 정보는 GIS 환경에서 구축하였으며, 우도비를 이용하여 지표변화 예측도를 작성하였다. 분석결과, 도시지역 및 농업지역 지표변화에 가장 큰 영향을 미치는 주제도는 고도, 하계망, 인구밀도, 도로, 인구이동, 총사업체수, 지가 등이다. 또한 산림지역 지표변화에 영향을 미치는 주제도는 고도, 경사도, 인구밀도, 인구이동, 지가 등이다. 지표변화 분석결과, 도시지역은 금강을 중심으로 구도심과 신도심지역의 도시 확산이 이루어지고, 인터체인지 및 국도를 따라 시가화 지역이 확산 될 것으로 예측되었다. 농업지역은 금강의 소지류 및 인접지역과 연결되는 국도주변 지역이 변화가 일어날 확률이 높다. 산림지역은 대부분 남동쪽에 위치하고 있는데, 그 원인은 밤나무 재배단지가 본 지역에 넓게 나타나면서 산림훼손이 일어날 확률이 높은 것으로 예측되었다. 예측비율 곡선을 이용하여 검증한 결과, 지표변화가 일어날 확률이 가장 높은 상위 $10\%$지역에서 도시지역은 $80\%$, 농업지역은 $55\%$, 산림지역은 $40\%$정도의 예측능력을 보였다. 따라서, 본 통합 모델은 산림지역 예측에는 부적합한 것으로 볼 수 있어서, 향후 새로운 주제도 선정 및 예측모델 등이 필요하다. 결론적으로 본 방법은 향후 토지피복 변화 연구를 위한 효과적인 방법 중의 하나로 적용될 수 있을 것으로 기대된다.
