There was a rapid population change accompanied with changes in population structure recently in Korea. The changes were nationwide though greater in rural, where the population decreased steeply, through the internal migration from rural to urban. There, in the structure of Gun's population, severely distorted features have been shown in the study. Also, the structure differ greatly by Gun. It indicated that the rural problems were much more serious than anticipated when analyzed generally. It tells us that we should consider the problems related with different population structure in developing the programs for the rural.

A local government is not a group under central government, rather it fulfills the function independently as a economic social administrative unit. Belief and role of chief of regional government, and citizen's understanding and interest regarding importance of an election pledge are getting higher. Thus, this study researches election pledges which can be a main variable of urban plan. Especially, the study attempts to analyze impacts of election pledge on urban spatial structure and regional economic structure. When relationship between election pledge and Use Zoninig change were analyzed, the result showed that development related entire use Use Zoninig changes were related with election pledge. When it was subdivided according to each use area, relationship of use area change among election pledge and urban spatial structure found to have relatively high in resident area. In addition, relationship between population factor and election pledge was high. This can be judged as election pledge and urban spatial structure change have relationship. Particularly, sectors related with residents are expected to have high correlation. As a result, pledges regarding general welfare administrative part were a few at areas with many pledges regarding regional economic development. So, it can be classified as regional economic development oriented pledge suggesting area and welfare administrative oriented suggesting area. Through realization of these pledges, it might be able to affect urban spatial structure changes.

This study examines the impacts of land cover changes on the East Asia summer monsoon with the National Center for Atmospheric Research Regional Climate Model (NCAR RegCM2), coupled with Biosphere Atmosphere Transfer Scheme (BATS). To assess the goals, two types of land cover maps were used in the simulation of summer climate. One type was NCAR land cover map (CTL) and the other was current land cover map derived from satellite data (land cover: LCV). Warm and cold surface temperature biases of $1-3^{\circ}C$ occurred over central China and Mongolia in CTL. The model produced excessive precipitation over northern land area but less over southern ocean of the model domain. Changes of biophysical parameters, such as albedo, minimum stomatal resistance and roughness length, due to the land cover changes resulted in the alteration of land-atmosphere interactions. Latent heat flux and wind speed in LCV increased noticeably over central China where deciduous broad leaf trees have been replaced by mixed farm and irrigated crop. As a result, the systematic warm biases over central China were greatly reduced in LCV. Strong cooling of central China decreased pressure gradient between East Asian continent and Pacific Ocean. The decreased pressure gradient suppressed the northward transport of moisture from south China and South China Sea. These changes reduced not only the excessive precipitation over north China and Mongolia but also less precipitation over south China. However, the land cover changes increased the precipitation over the Korean Peninsula and the Japan Islands, especially in July and August.

This study was carried out to understand the mean of neighbourhood and community organizing model on lived experiences of their organizing and members which had changed. The methods of collecting data was progressed in depth interview. According to study questions and analysis challenges based on theory, we analyzed texts. outcome of study we understood experiences of their organizing and members which had changed. In changing phases of organizational dimension, meaning of 'the discovery of the community problem' was extracted. In this time, organization's members set the goal and experience qualitative and quantitative changes of organization. On the other hand, changing phases of individual dimension were followed, which are 'escaping from locked life', 'reconstruction of self image', 'reconstructing the meaning of both family and self-concept' as well as 'reconstructing the meaning of both neighbourhood and self-concept'. Conclusively, we suggested practical implication, which might increase the effect of neighbourhood and community organizing model.

Recently, the land degradation and pasture erosion in Tuv, located around Ulaanbaatar of Mongolia, have been increasing sharply due to escalating developments of mining sectors, well as the density of populations. Because of that, we have chosen the urban and mining area of Tuv for our study target. During the study, the temporal changes of land cover in Tuv, Mongolia were observed by the Landsat TM/+ETM satellite images from 2001 to 2009 that provided the fundamental dataset to apply NDVI and K-Mean algorithm of Unsupervised Classification and Maximum likelihood classification(MLC) of Supervised Classification in order to conclude in land cover change analyzation. The result of our study implies that the growth of mining area, the climate change, and the density of population led the land degradation to desertification.

전 국토의 산지 비율이 높은 우리나라는 산림지의 특성이 수질에도 많은 영향을 미치고 있다. 산림지역의 화재에 있어 산림이 갖는 수질, 토성의 변화와 발생한 연소 퇴적물, 유기물로 인해 수자원에도 악영향을 끼치게 된다. 산불은 단순한 산림지의 자원 유실뿐만 아니라 토양층의 물리적약화와 강수저류 효과를 떨어뜨려, 산불 후 유출의 증가를 보인다. 삼척시의 산불 선행연구에 따르면, 산불 발생 직후, 지역의 직접 유출이 기저 유출보다 높게 나타났다. 이에 따라, 모든 수질인자의 평균 농도는 비발생지역에 비해 발생 지역의 농도가 현저하게 증가하였으며, 이 중 T-N, T-P, SS의 농도가 특히 크게 나타났다. 또한, 계류 수질의 경시적 변화를 분석한 결과, BOD와 COD는 산불 발생 최소 4개월의 기간을 거친 후 점차 안정화하는 모습을 보였다. 다만, 산불로 인해 훼손된 물 환경의 상황을 복구하고자 하는 연구의 데이터가 부족한 실정이다. 따라서 본 연구는 2022년 4월 산불이 발생한 강원도 양구군 양구읍 송청리 비봉산 일대의 산불 유역을 대상으로 산불에 따른 물 환경의 변화를 밝힘으로써 산불로 훼손된 지역의 효과적인 수질 회복과 물 환경 보전 대책 수립을 위한 자료를 제공하고자 수행하였다. 2023년 4월 양구 비봉산의 산불 복구 작업이 본격적으로 시작되는데 복구 전 현재 수질의 상황을 살펴봤다. 조사 지역은 비봉산 일대의 산불 지역과 비발생 지역, 오봉산 일대까지의 유역 출구 총 7개의 지점을 선정하였다. 기본 수질항목은 현장에서 YSI PROPLUS (Mobile Multi Sensor Meter)를 이용하여 측정하였고 채취한 시료는 무균 채수 병에 담아 실험실로 운반하여 SS (Suspended Solids), TP(Total Phosphorus), TOC (Total Organic Carbon) 항목에 대해 수질오염공정시험기준에 의거하여 분석하였다. SS, TOC, t-p의 경우, 지정학적 특성, 산불에 의한 퇴적물들의 변화와 토양의 형태 및 식생의 변화로 인한 결과의 차이를 보였다. 1년이 지난 지금 산불 직후처럼 높은 수치는 보이지 않았다. 그러나 아직 복구 작업이 제대로 진행되지 않아 그 영향에 대해 무시할 정도로 안정화되지 않았다. 본 연구는 산불 발생 후 강우 및 토사유출에 대한 비 산불 지역과의 차이를 살펴봄으로써 수질 오염원으로 작용할 수 있는 가능성을 기초자료로 제공될 것이다. 또한, 수처리 기술개발을 포함한 예방책을 만들어 내는데, 기초자료로 활용할 수 있길 바란다.

The objective of the study is to analyze the impact of zone adjustment by comparing the changes from 2011 to 2018 of social and environmental factors such as the special-purpose area, actual construction activities including building development, land use environment, and officially assessed individual land price in the areas released from the National Park Zone during the second National Park Zone adjustment during 2010 to 2011 with the social and environmental factors in the areas that remained in the National Park Zone during the same period. We intended to investigate the problems of the second National Park Zone adjustment and explore alternative implications for the third National Park Zone adjustment. As for the special-purpose area, 80.4% of the released areas were converted to planned, production, and conservation area while 15.6% changed to the agricultural area, and 4.0% remained as the natural environmental conservation area. Regarding the change in building development scale, the average size of construction in the released area since 2011 was $106m^2$ while that in the retained areas was $91m^2$. For the land use environment, the rate of change from the natural area to developed area was 1.9% in the released area and 0.7% in the retained area. The officially assessed individual land price increased by 11,911 won in the released area and 4,413 won in the retained area. Although both areas showed an increase in the land price, the difference of officially assessed individual land prices was about 2.5 times. The problem concerning the private property rights of local residents in the national parks is still a challenge, but the second National Park Zone adjustment has resolved the problem significantly. Accordingly, it is necessary to offer the benefits for the residents in the national park area by analyzing the park zoning and park facility planning to present the rational alternative. It is also necessary to establish a support system that encourages the collaborative cooperation between the park authority and residents and assures that the residents to have pride in the national park.

Pyeongtaek port, opened in 1986, has played a role as an international trading port. Pyeongtaek city which is a hinterland with Pyeongtaek port has both landscape of city and rural area. Aims of this study is investigating the regional change of Pyeongtaek city according to the opening of Pyeongtaek port: the change in population and land value by the average distance(27.3km) between Pyeongtaek port and each region and the change in industry and regional industry with location quotient of region. The increasing rate of population and people who work for industry showed an aspect of rising as a place locates near Pyeongtaek port, yet the increasing rate of land value showed little differences. In short, as the area is closer to Pyeongtaek port, the number of population and employees are higher. Yet, the increasing rate of the land value showed little difference. The study showed that manufacturing industry is specialized in rural region(eup myeon region), and tertiary industry is specialized in urban region(dong region) of Pyeongtaek city according to location quotient.

기후변화로 인해 수자원에 발생할 수 있는 가장 큰 영향은 유역에서의 유출량의 변화이다. 유출량의 변화는 가용한 수자원양의 변화를 의미하므로 미래 가뭄 등에 대한 대책 마련 등을 위해 합리적인 추정과 분석이 필요하다. 본 연구에서는 기후변화로 인한 유역 유출량의 변화를 추정하기 위해 기상청의 과거 기상관측자료와 RCP 시나리오 자료를 기반으로 SWAT-K와 Tank 모형을 이용해 팔당댐 상류지역에서의 유역 유출량을 모의하였다. 특히 팔당댐 상류는 수도권의 2천만명에 가까운 인구에 대한 수자원의 공급을 담당하는 유역으로서 이 지역의 가뭄은 국가적인 재난을 일으킬 수 있어 매우 중요할 것이므로 기후변화에 의한 가용 수자원의 변화를 미리 예측해 볼 필요가 있을 것으로 판단되었다. 모의 시 모의 대상 지역에 대한 지형학적 인자와 인문학적 인자 등은 변화가 없는 것으로 가정하고 단순하게 기후변화에 의한 강수량과 증발산량 등의 증감만 있는 것으로 가정하였으며, 모의한 결과를 바탕으로 갈수량과 홍수량 등에 대한 빈도를 분석하여 유출의 변화를 살펴보았다. 분석 결과를 통해 팔당댐 상류의 유역 유출량 변화를 통계적으로 예측해 볼 수 있으며, 해당 자료는 지자체의 수자원계획 수립 등에 유용하게 활용 될 수 있을 것으로 판단된다.
