This paper studies the problems and improvements of government real estate policies. Moon Jae-in government shifted toward regulation and pledge to curb the tax imposed by speculators. It strengthened regulations on reconstruction and bank loans rather than supply, and raised capital gains taxes. As the government implemented measures, emphasizing political logic rather than the economy, the market is unstable and the economy is in a recession. Land has increased the vicious cycle of problems due to population growth, industrialization, urbanization, and wealth growth. Mis-established land policies not only accelerate land prices, but also accelerate the use of disordered land and lead to disruptions in the trading order. In addition, real estate is so difficult to recover from the land problem that it is difficult to contain water that has been spilled once. This is called the irreversible nature of land. Once the land price rises, it is difficult to regain control and reckless development leads to the destruction of the ecosystem, making it difficult to return. This is why such a complex real estate issue should not be implemented as if it were a punishment in a short period of time with government policies. This paper aims to examine the problems of real estate policies and to examine ways to improve them.

Recently, the land area for many people has been limited because of industrialization and modernization in Korea. The large-scale constructions like the reclamation development projects have been progressed to resolve this problem mentioned above. Therefore, as many of the useful construction materials as possible are needed to perform the largescale construction projects. Many studies for the utilization of pond ash which has a similar characteristic of sand have been conducted and there has been often occurred many structural problems on roadbed in winter. Therefore, the characteristics of the freezing and thawing for Controlled Low-Strength Material(CLSM) using pond ash were analyzed and evaluated by unconfined compressive strength test and mass loss test in this study. As a result of this study, it was confirmed that new CLSM using pond ash with cement(8.2% by weight) was able to stand for the freezing and thawing behavior and was satisfied with the standard of Portland Cement Association.

This study focuses on the relationship between housing sale prices and Jeonse prices, amid a recent surge of Jeonse price and Jeonse-to-housing sale price ratio. There are many studies about the relationship between house prices and Jeonse, but they couldn't fully explain what makes them spike up. In addition to this relationship, this paper deals with the difference of Jeonse system on regions and price levels. Using Granger causality and Spearman's Correlation Coefficient, the outcome is drawn. As the result, the expected rate for housing sale prices effects on the Jeonse-to-housing sale price ratio. The higher on sale price, the lower the Jeonse-to-housing sale price ratio regarding the region difference.

The Cadastral Resurvey Project implementation process must make some landowner better off (area increase) and others worse off (area decrease) by changing the boundaries of ones' own land. This study focuses on the Standard way to calculate compensation if landlords are worse off or charge otherwise. For this study, we analyze the compensation by comparing appraisal value method and a method based on the individual land value by public announcement in theoretic manner. we collected considerable amount of data on both appraisal values and the individual land values by public announcement. We found the difference of compensation between appraisal value method and a method based on the individual land value by public announcement. In this study, more desirable and efficient implementation strategy for government agency who is in charge of cadastral project nationwide is suggested.

The purpose of this study is to evaluate landscape characteristics of watersheds in the Nakdong River Basin for identifying the groups of watershed with similar landcover patterns by using Geographic Information System and statistical technique. According to the results based on the cluster analysis using cluster analysis tool in the ArcGIS 8.3 program, 22 sub-watersheds were classified into three types; "Forest watershed", "Agriculture watershed", and "Urban watershed". In the forest watershed that has the least potential of ecological disturbances by human, a forest management approach based on geographic conditions and coverage types, etc., should be developed to sustain the ecological and environmental functions of forest. For the agriculture watershed, environmental-friendly agricultural techniques should be performed in the particular enhancement of riparian buffer zone to the prevent direct inflow of soils, fertilizers, and other chemicals into the stream network. Finally, in the urban watershed, an environmental-friendly plan that may increase the ratio of pervious surface and amount of green-space to should be reserved.

기후변화는 범지구적으로 당면한 과제로서 국제적으로도 이에 대한 저감 완화대책 수립 및 시행에 힘쓰고 있다. 이러한 세계적 관심에 따라 최근 우리나라도 국가 물 안보에 대한 보고서 등의 개정에 관심을 기울이고 있는 실정이다. 그러나 이러한 당면한 문제에 대한 계획을 수립하기 위해서는 무엇보다도 직면하고 있는 사실에 대한 이해가 필요하다. 특히 우리나라의 경우에는 비록 국토가 좁은 나라에 속하지만 호우의 계절적 지역적 편차가 큰 편이기 때문에 무엇보다 지역별 변화에 대한 연구가 필요한 실정이다. 지금까지의 수문학 분야의 기후변화에 대한 영향 연구는 대부분 유역을 중심으로 수행되어 왔다. 이는 자연현상을 모의하기 위해서이나 실제적으로 국가예산 계획수립 및 투입은 주로 지자체단위로 이루어지기 때문에 지자체별 영향에 대한 연구도 매우 중요하다. 따라서 본 연구에서의 지역적 범위는 지자체단위로 하였다. 이러한 지역별 분석의 범위는 최소 단위의 의사결정자들을 위한 범주가 되면 이상적이겠지만 실제적으로 이는 여러 가지 이유로 어려운 점이 있기 때문에 본 연구에서는 우리나라의 광역지자체를 공간적 범위로 설정하였다. 또한 기후변화 시나리오는 IPCC(Intergovernmental Panel on Climate Change) 4차 보고서의 탄소배출 시나리오 중 널리 사용되고 있는 3종(A1B, A2, B1) 선정하였으며, GCM은 4종(CNRM: CM3, CSIRO: MK3, CONS: ECHO-G, UKMO: HADCM3)을 적용하였다. 최종적으로 각 광역자 치단체별-시나리오별-GCM 별로 4개의 기간 구간 (2080-2009, 2010-2039, 2040-2069, 2070-2099)으로 나누어 평균 일최대강우량 및 연총강우량의 변화를 분석하였으며, 이러한 분석법은 일본 국토교통성의 경우 이러한 방법에 일최대강우량에 적용하여 미래 기후변화로 인하여 치수안전도 변화 분석에 활용한 바 있다.

In the Seoul Metropolitan City, the PM(pariculate matter) application used by the citizens provides the PM concentration of the nearest monitoring stations located on the PM monitoring stations. Currently, the selecting method of the PM monitoring network considered by the Ministry of Environment is based on considering the monitoring station distribution and population density only. In this study, we analyzed the distance between PM monitoring station and the administrative center point in addition to the above considerations. The number of test sites was verified and the range of coverage of each monitoring stations was indicated by using the Voronoi algorithm and hexagon grid. The spatial position problem of the PM monitoring station was suggested by spatial data analysis. The variables of spatial data analysis are single-family houses, apartments, $1^{st}$ class neighborhood, $2^{nd}$ class neighborhood, garbage disposal plant, hazardous material disposal facility, factory, and the density map. The analysis result of the selection criterion considering the additional variables for new PM monitoring stations was presented, in addition to the selection criteria provided by the Ministry of Environment.
