The rebuilding or redevelopment of buildings in the Readjustment Project District is generally built high-rise buildings. It sometimes makes our residential area to be uniform in height and disharmony with surrounding houses and infrastructure. Then this research examines the landscape effects of the height of buildings built using landscape simulation on hillside and level ground. We suggested that it was desirable for a land readjustment project district to be managed by District Plan and Development Density Controlled Area. In addition, a consideration for the introduction of Average Floors is needed to mitigate the uniform and disharmony with surroundings.

공공시설물 건설을 위한 적지분석을 위해서는 대상지에 국유지 또는 시유지(지자체소유)의 포함비율이 중요한 요소가 된다. 일반 건설과는 다르게 사업예산을 축소하기 위해서 국가 또는 지자체소유의 토지를 포함할 수 있다는 특수성이 있기 때문이다. 사유지를 수용할 경우 소유자와 필지수 그리고 지가 등이 판단요소가 된다. 뿐만 아니라 물리적조건으로 경사도, 향(aspect), 교통편이성 등이 동시에 분석되어야 한다. 본 연구에서는 속성과 공간적인 분석을 통해 공공시설물의 적지분석을 수행하였다.

Interest in communities continues to grow. Policies to support the community are also being strengthened. However, the problem of developmentalism that destroys the community is still present. Although it has been revealed clearly in the Four Major Rivers project, developmentalism still dominates the community. Reform of developmentalism is very important for the protection and upbringing of the community. It can be done through reforms of institutions that make developmentalism work. It can also be a result of reforms in development laws and development agencies. The reform of laws related to the land compulsory acceptance system and the reform of the development corporations including the Water Resources Corporation(the K-Waters). Here, it is necessary to transform the composition of 'community versus state' into a composition of 'community and state'. Communities and states should have complementary relationships for good societies. The reform of developmentalism is a core task.

우리나라의 수질오염에 대한 규제는 주로 호소 및 하천의 수질을 향상시키기 위하여 하수 및 공장폐수 등 점오염원을 중심으로 관리되어 왔으나 강우와 함께 대량 유출된 비점오염원은 수용하천의 자정능력을 감소시키고 있고 이로 인해 하천과 호소의 수질은 향상되지 못하고 있다. 또한, 농촌지역에서 배출되는 비점오염원은 정확한 기작의 분석이 안 되고 있으며, 비료$\cdot$농약의 사용 증가에 따라 영양염 및 유해물질에 의한 수질오염의 영향이 증가되고 있는 실정이다. 본 연구는 농촌지역의 강우-유출로 인한 비점오염물질의 유출특성 및 배출부하량을 조사하기 위하여 영산강권역의 외남천을 대상으로 조사하였다. 대상 유역의 토지용도 구분은 (1)논지역, (2)밭지역, (3)산지지역, (4)농촌주거지역, (5)복합지역(논, 산지)으로 구분하였다. 시료의 채취는 강우시 5회에 걸쳐 조사하였으며, 2L 용량의 무균채수병에 채취한 후, 아이스박스에 $4^{\circ}C$이하로 보관하여 24시간 이내로 실험실에 운반하여 실험하였으며, 매회 시료 채취 주기는 강우유출이 발생하기 전부터 강우 종료 후 유출량 변화가 없을 때까지 $9\~12$단계로 세분하여 유출량과 pH, DO, BOD, COD, SS, T-N, T-P의 농도를 측정하였다. 본 연구에서 조사한 결과 토지이용별 비점오염원의 SMC를 살펴보면 BOD의 SMC는 $4.38\~11.02mg/{\ell}$, COD의 SMC는 $7.07\~23.99mg/{\ell}$, T-N은 $1.57\~5.20mg/{\ell}$, T-P는 $0.11\~0.274mg/{\ell}$의 범위를 갖는 것으로 나타났으며, 전반적으로 논 지역에서 비교적 높게 나타났는데 이는 농작물의 경작에 따른 시비법의 영향으로 판단된다. 또한, 비점오염원의 유출특성을 보면 전반적으로 초기 오염물질 유출특성 갖는 것으로 나타났다.

PSM is widely used pricing tool in field by the reason of data collection convenience and analytical intuitiveness. However, In high involvement environment, strategic respondent bias influence in reducing the price. By using 3 empirical cases of LH apartment for sale, We found that latent consumers' recognition of the range of acceptable and the range of optimal price are lower than real estate agent representative respondents'. This phenomenon is considered loss aversion effect of prospect theory to reduce loss by reducing price, and more influenced in high involvement situation than latent consumer respondents'. Also we found PSM result using real estate representative data is more useful in real market than latent consumers data distorted by loss aversion effects. The meaning of this study is finding some limitation in PSM using consumer data generally used. In further study, development of PSM measurement tool to minimize the effect of strategic bias are need to be studied. Also some new approaches in reinterpretation of the range of acceptable price and the range of optimal price are need to be followed.

Based on the spatial and land price data of innovation cities and their periphery areas in Korea, this study examines the degree and timing of changes in land price in relation to projects concerning innovation city. The study result confirms that the current system is inconsistent with the principle of restitution of development gain and therefore, this study attempts to seek improvement measures so that the current system can better fit the principle. The analysis reveals that most innovation cities, excluding Sinseo-dong of Daegu and Ujeong-dong of Ulsan, recorded a statistically significant increase in land prices since 2005, compared to those of their neighboring areas. It can be said that the information related to projects concerning innovation city was reflected in the land price since 2005. However, the standard land price pursuant to Article 70 of the Land Compensation Act is the officially assessed land price released on 1st of January 2007, and this official land price was actually applied to the compensation process. Therefore, estimating the compensation amount for land expropriation based on this land price will contradict the principle of restitution of development gain. In other words, despite the fact that development-related information was already reflected in land prices of innovation cities from 2005 to the end of 2006, the compensation process were carried out without institutional arrangements or efforts to exclude such reflection. To solve this problem, this study makes two suggestions. First, it is necessary to cast aside the limitations of the official land price that can be retroactively applied in accordance with Paragraph 5 of Article 70 of the Land Compensation Act, and instead apply the land price which is the most latest but deemed to have no reflection of development gains. Based on this revised standard land price, if the compensation amount is corrected by the average inflation rate and the average rate of increase in land price during the period until the time of the recognized land price, the amount would better satisfy the principle of restitution of development gain. Second, it is necessary to clearly stipulate the standards of development gains being reflected on the land price by including it in the secondary legislation. Under the current system, it is highly likely that appraiser's arbitrary interpretation on development gains is included in the process of calculating the amount of compensation for land expropriation. In this regard, it is necessary to improve the standards on determining whether development gains are reflected based on the results of this academic research and the existing guidelines for appraisal of compensation for land expropriation published by the Korea Association of Property Appraisers.

In order to study the water quality status and its causal environmental factors, the water quality variables of chemical oxygen demand (COD), chlorophyll a (Chl a), Total phosphorus (TP), and total nitrogen (TN), the hydrogeomorphologic variables of water level fluctuation, total water storage, dam elevation, watershed area, and shoreline development index, and the land cover variables of forest, agricultural area, and urbanized area in the watershed were investigated in total 73 reservoirs with various operational purposes, water level fluctuation and geographical distribution in South Korea. The water quality was more eutrophic in the reservoirs of the more urbanized and agricultural area in the watershed, the low altitude, the narrow water level fluctuation, the narrowed watershed area, and the more circular shape. In terms of the purposes of reservoir operation, the reservoirs for agricultural irrigation were more eutrophic than the reservoirs for flood control. The results of the variable selection and path analysis showed that COD determined by Chl a and TP was directly affected by water level fluctuation and the shoreline development of the reservoirs. TP was directly affected by the urbanized area of the watershed which was related to the elevation of the reservoir. TP was also influenced by the water level fluctuation and the shoreline development. In conclusion, the eutrophication of the reservoirs in Korea would be influenced by the land use of the watershed, hydrological and geographical characteristics of the reservoir, water level fluctuation by the anthropogenic management according to the reservoir operation purpose, and the location of the reservoirs.

This research explores the potential of purchased rental housing as a versatile solution for residential development. By focusing on smaller-scale construction compared to large residential complexes, purchased rental housing projects offer benefits such as shorter project durations and enhanced flexibility to accommodate residents' needs. This public-private collaboration extends to community planning, enabling tailored models beyond traditional rental housing frameworks. Currently, purchased rental housing, which is predominantly comprised of multi-unit house, multi-household house, and rowhouses, is in high demand and in short supply in metropolitan areas. Utilizing volumetric modular housing, considerations for module size and transportability are paramount, while advancements in construction methods, particularly prefabrication, offer efficiency and quality benefits. This study proposed three construction techniques to plan modular housing models and enhance construction and demolition efficiency: planning without columns in the middle of the unit, core production using volumetric modular construction methods, and industrialization of construction components alongside dry construction methods. Utilizing these methods, a new construction model for purchase lease housing was presented to address the need for new housing in the context of ageing housing renovation and demand fluctuations. The model comprises 16 units, with sizes ranging from 36 m² to 54 m², and can be applied on sites larger than 600 m² with access to roads wider than 6 m. This promotes cluster-style development, which in turn increases construction efficiency in nearby plots.

To designate rural landscape spatially, land use and topographic features for 383 of "Ri"s or "Dong", which is a basic administrative unit in Korea, were analyzed using GIS application. We have categorized rural landscape into three types such as agricultural, natural and urban landscape by land use. On the basis of spatial landscape pattern, rural area could be classified into 6 groups of Mountainous area (MA), Mountainous village area (MV), Developing mountainous village area (DM), Plain agricultural area (PA), Developing plain village area (DP) and Urbanized area (UA) according to the ratios of land for agricultural and urban use as the criteria. In MA, the ratio of upland area including orchard was slightly larger than that of paddy, while that of paddy was about 1.5 times larger than upland in other groups. Forested area was distributed more than two-thirds among natural landscape area in MA, MV and DM. In plain types (PA and DP), the ratio of irrigated paddy was extremely larger than partially irrigated paddy and the ratio of water body area among the natural landscape area was two times as large as that of forested area. The ratio of land for industrial and livestock facilities among urban landscape area were 20% or more in MV, DM and DP, and it means that these facilities are mainly distributed in the developing ru ral area where residents and industry are closely related each other. According to the relative ratio of sloped land of 6 categorized areas, the MA area have lots of land with E and F slopes and MV and DM have all grades of sloped land evenly distributed in relative to other types of rural landscape. It has been showed that PA, DP and UA occupied more than two-thirds of land with A or B slope. In case of the analysis of topological distribution in 6 types of rural landscape, there were overwhelmingly lager highland areas in MA. Conclusively, we have confirmed that 6 types of rural landscape classified by land use pattern in 3 categorized areas such as agricultural, natural and urban landscape area would be useful for the management of rural area. For development of sustainable agriculture and the preservation of rural amenity, proper management ways should be properly applied according to rural landscape patterns.
