Areas developed through land reclamation projects have huge economic advantages in terms of supplying lands that can be used for farmlands, urban areas and etc., however have relatively small areas of grasslands and densely located buildings compared to inland cities. Hence, an urban heat island is occurring in these areas due to this characteristic, and in particular, the urban heat island in Cheongna International City is getting serious. In this study, the urban heat island in Cheongna International City was evaluated and analyzed by classified into the three periods after the reclamation project: farmland(2001-2008), development(2009-2013) and artificial grassland(2014-2020). The land cover map and Landsat time-series imagery were utilized for measuring the differences of the land surface temperatures between the urbanized areas and the grassland/forest areas in Cheongna International City. The statistical results showed that the differences in the land surface temperature between these areas were calculated to be at most 0℃ during the period of farmland, at most 3.60℃ during the period of development, and at most 2.51℃ during the period of grassland. This study proved that the urban heat island phenomenon increased when the urbanized areas increased, and the urban heat island phenomenon decreased when the artificial grassland areas increased in Cheongna International City where the reclamation project was carried out. The statistical results derived through this research can be used as the reference data for identifying the urban heat island problem in urban planning and establishing the reduction plan.

The existing tax law provides that alloted resident tax on corporation tax is apportioned in accordance with the number of employees and total building area as of the end of business year. Through a case analysis, however, this study found that such apportionment is not applied to businesses whose operation was already withdrawn as of the end of business year. To solve this problem, the study proposed that the apportionment of alloted resident tax on corporation tax should be made in accordance with the number of employees and total building area in the middle of business year and a standard of corporation tax assessment, that is, sales assessed according to the value-added tax law. This proposal already proved to be reasonable by lots of actual cases that showed the realization of balance in taxation. To make more precise standards of the above mentioned apportionment, then, the study proposed that in the ordinance of the local tax law, 'as of the end of business year' should be replaced by 'in the middle of business year'. In addition, 'in the middle of business year' should be defined as 'in the period of continuous business' from the date of business end in the previous year to the date of business end in the present year and the length of the period should be calculated by month. These moves would bring more transparent and balanced local tax assignment than present under the local tax law.

Potentials of AR CDM project in North Korea are assessed and feasible land area for AR CDM project is estimated. According to our estimation, There could be 515,000 hectares of forest lands deforested before 1990 in North Korea and 8,854 hectares at the regional level of Gae-sung City, which are eligible for AR CDM project, based on researches of satellite image analyses conducted from 1980's to 1990's. A baseline scenario assumed 44.73 tones of carbon stored in soil per hectare with no vegetation above ground remained during the project period following the default value of IPCC's Good Practice Guidance for LULUCF considering soil structure, climate and land use of the project area. The scenario also assumes that black rocust (Robinia pseudoacacia) is planted and the CDM project is implemented for 20 years. The costs for producing greenhouse gases CER (certified emission reduction) credits include costs of tree planting and forest management, and costs of project negotiation and transactions for issuing the credits. It is estimated that 376 tones of carbon dioxide per hectare can be accumulated and 503 temporary CER credits per hectare and 265 long-term CER credits per hectare could be produced during the project period. It is estimated to cost US$ 4.04 and US$ 7.67 to provide one unit of temporary credit and long-term credit, respectively. These values can be regarded as the cost of conferring emission commitment of a country or a private entity. However, it is not clear which option is better economically because the replacement periods are different in these two cases.

The purpose of this study is to analyze the impact which the plan characteristics of Residential Land Development Projects have on land price changes in the project district and to derive policy implications for the efficient promotion of these projects. For this purpose, we analyzed the promotion land price change progress of Residential Land Development Projects step-by-step. After theoretical consideration and a review of the references, 16 plan characteristics of Residential Land Development Projects affecting land price changes were selected ((1) The rate of land price change, (2) Business area, (3) Residential land ratio, (4) Commercial land ratio, (5) Semi-residential land ratio, (6) Neighborhood facilities land ratio, (7) Apartment house ratio, (8) Street ratio, (9) Park & green ratio, (10) Ratio of land for schools, (11) Site development cost for $1m^2$, (12) General residential area ratio, (13) Semi-residential area ratio, (14) Commercial area ratio, (15) Semi-Industrial area ratio, and Natural green area ratio). We used SPSS Version 20.0 to analyze the impact of the 16 selected plan characteristics on the land price changes. As a result, it was found that the land price began to rise two years (before/after?) the appointment of the district and became stabilized after the completion of the project. The plan characteristics that affect the land price changes were found to be the (2) Business area, (4) Commercial land ratio, (6) Neighborhood facilities land ratio, (8) Street ratio, (11) Site development cost for $1m^2$, and (12) General residential area ratio.

정부는 축산업 허가제 시행에 맞추어 허가대상 농가의 부담을 최소화하기 위해 축사시설현대화사업 예산을 대폭 확대하여 허가기준에 맞는 시설을 갖추도록 할 계획이다. 한편 무허가 축사의 경우는 건축법과 축산법은 별도의 법률이므로 기존 무허가 축사는 축산업 허가를 받을 수 있도록 할 계획이나, 신규 진입농가 및 사육면적을 확대하는 농가에 대해서는 적법한 축사에 한하여 허가토록 할 계획이다.

The purpose of this study is to analyze the housing price variation within the redevelopment project district, affected by the characteristics of project and implementation stage. This study implemented the hedonic price model employing the actual transaction price with 24 dependent variables from 2006 to 2016 inside 19 redevelopment districts in Seoul. Research finding indicates that the larger ratio of the number of tenants and general distribution, the smaller ratio of rented households and the more positive effect of housing price. It is noteworthy that this study demonstrated the actual transaction price of houses located within the project districts by implementation stage. This study is expected to help the policy makers, the developers and the investors make more reliable decisions on the feasibility study related to the redevelopment project.

Considering that the Seoul subway sector is expected to see extension of lines, addition of stations, and changes of operating companies, a review is needed to identify ways to eliminate or minimize financial deficits in its operation. As for deficits from the operation, additional businesses for extra income have been suggested as alternatives, but inasmuch as Western urban development (that of the subway containment area) may not be applicable to Korean settings, a practical alternative is to maximize income by efficient use of rental facilities that are located inside station properties. This alternative requires the estimation of appropriate facility size and rent for each station; few, however, have addressed this topic. At this juncture, this study aimed to draw an equation for estimating the sizes and rents of station properties by reflecting characteristics of lines and locations; a case study was performed for Subway Lines 5 and 6. Analytical findings are that rental facility sizes and rental incomes are affected mainly by the subway ridership and transport revenues, whereas the influence of ground-level commercial activity is relatively weak. A particularly great influence was found to be the value of apartment housing in areas through which the subway lines run. Stations on Line 5, which runs through areas of high-value housing, were assigned smaller facility sizes and higher rents than those on Line 6, which covers areas with relatively low housing value. The equation suggested in this study would make possible more practical feasibility studies when the need arises to estimate sales of new or extended facilities affiliated with stations.

The policy introduced recently in order to promote small-size reconstruction housing projects for rehabilitating downtown area consists of aged multi houses has been little practiced, as preferential provisions for such projects are more likely applicable for large projects. Several expert interviews and surveys were conducted to find efficient clauses to overcome the problems and their relative weights. As the results, it is revealed that 'relation of floor area ratio' and 'relaxation of building height limit criteria' are the most effective whereas 'purchasing and operating of residents' common facilities with public fund' is little. The study results would be a great interests for public institutions to rebuild aged housing area without destroying local communities and to provide socially disadvantaged class with rental housing at the same time.

최근 기상이변으로 인한 이상홍수가 전국적으로 빈발하게 발생하고 있고 홍수에 의한 인명과 재산피해는 과거와는 비교할 수 없을 정도로 규모가 커지고 있다. 이와 같은 수해 피해를 경감시키기 위한 치수사업의 필요성은 인식하고 있으나 사업타당성을 정확하고 객관적으로 분석할 수 있는 경제성분석 방법이 미진한 실정이다. 따라서, 본 연구에서는 현재 국내에서 사용중인 치수경제성분석의 문제점을 파악하고 선진외국의 사례와 비교분석하여 개선방향을 도출하고 현재의 여건에서 정확성을 높일 수 있는 방법을 검토하고자 한다. 주된내용은 예상피해지역의 일반자산조사(건물, 건물내용물, 농경지, 농작물, 사업체유형${\cdot}$재고자산)를 통하여 $100\%$피해규모를 산정하고, 이 후에 침수심조건에 따라 피해율을 적용하여 예상홍수피해액을 산정한다. 기존의 침수면적 피해액의 회귀분석법과는 달리 각지역(시${\cdot}$군)의 통계연보를 중심으로 피해액을 산정하기 때문에 지역특성을 반영할 수 있으며, 또한 GIS와 연계되어 침수면적뿐만아니라 침수심의 공간적 분포를 검토하여 피해액을 보다 정확하게 산정할 수 있다.
