The multifamily housing has various advantages in construction cost, land-use intensity. KRIHS(1997) recommended the proper scale of th multifamily housing as 800 households in constructability, 1,000 households in facility compactability, 500 households in social aspect. At the early planning stage of project, the size of the multiftmily housing has, until now, been maximizingly considered under the regulation on which has been emphasized at the building volume ratio, land area, etc., except for the expenditure during the maintenance stage. This paper aimed at providing the proper size of multifamily housing in aspect of area and household number with maintenance cost at the early stage of project. For these, it took 곧 average cost function which is made from the 3-rd quardratic form and analyzes the unit increasing rate of the average cost. It surveyed in nationwide focused on the central heating system using diesel and kerosene. The number of samples is 88 and items of management cost is 11. The results are as follows ; first, 3rd-order quadratic function is proper at explaining the cost variation, considering the multicollinearity and statistics. Second, the proper size of multifamily housing is recommended with 83,000 $m^2$ on management area, 820 or over the 2,630 household number in aspect of total management cost.

Repeated use of land is depleting future resources and causing many ecological problems, prompting the need for a natural resource policy focusing on effective conservation. This study aims to identify methods based on international cases useful for introducing sustainable conservation of domestic natural resources. Currently, South Korea has developed and enforced many management and evaluation strategies for natural resources. However, due to limitations on policies and management, they show signs of strain. Therefore, this study compares and analyzes international conservation policies for nature and scenery, such as Germany's impact mitigation regulation, the USA's HEA (habitat equivalency analysis) and REA (resource equivalency analysis) policies, and Japan's three laws for landscape and greenery, to achieve the following three goals: first, find natural resources suitable for South Korea and define them. Second, plan goals for mitigation of total natural resources and build a basis for them. Third, establish effective complete plans for evaluating the total amount of natural resources.

Since the design Standard for Energy Conservation in Building was implemented in 2008 for the first time, building elements such as window and door should satisfy the minimum criteria to apply for a building. Though its regulation does not cover the whole building yet, recent demand to reduce energy consumption in building sector grows rapidly year by year and also draws a lot of interest to ensure the whole building level. For example, a Zero energy building, one of low-energy buildings, requires a customized solution to resolve the air leakage issue to meet the standards in achieving the high level of air tightness. In this study, six non-residential buildings were tested by fan pressurization method to observe the air tightness of whole building to suggest the construction guideline for air tightness of low-energy building. Five out of six tested buildings showed 0.27 to 1.16 h^-1 of number of air changes except one community center. These buildings were carefully constructed not only for building planning but also for parts where there was a concern of air leakage, thereby securing high levels of air-tightness. The construction skills were developed as a checklist to manage and supervise the construction site. It is our suggestion to use this checklist at construction sites for ZEB with the high level of air-tightness.

Along with the urbanization, the risk of urban flooding due to climate change is increasing. Flood regulation, one of the ecosystem services, is implemented in the different level of function of flood risk mitigation by the type of ecosystem such as forests, arable land, wetlands etc. Land use changes due to development pressures have become an important factor in increasing the vulnerability by flash flood. This study has conducted evaluating the urban flood regulation service using InVEST UFRM(Urban Flood Risk Model). As a result of the simulation, the potential water retention by ecosystem type in the event of a flash flood according to RCP 4.5(10 year frequency) scenario was 1,569,611 tons in urbanized/dried areas, 907,706 tons in agricultural areas, 1,496,105 tons in forested areas, 831,705 tons in grasslands, 1,021,742 tons in wetlands, and 206,709 tons in bare areas, the water bodies was estimated to be 38,087 tons. In the case of more severe 100-year rainfall, 1,808,376 tons in urbanized/dried areas, 1,172,505 tons in agricultural areas, 2,076,019 tons in forests, 1,021,742 tons in grasslands, 47,603 tons in wetlands, 238,363 tons in bare lands, and 52,985 tons in water bodies. The potential economic damage from flood runoff(100 years frequency) is 122,512,524 thousand won in residential areas, 512,382,410 thousand won in commercial areas, 50,414,646 thousand won in industrial areas, 2,927,508 thousand won in Infrastructure(road), 8,907 thousand won in agriculture, Total of assuming a runoff of 50 mm(100 year frequency) was estimated at 688,245,997 thousand won. In a conclusion. these results provided an overview of ecosystem functions and services in terms of flood control, and indirectly demonstrated the possibility of using the model as a tool for policy decision-making. Nevertheless, in future research, related issues such as application of models according to various spatial scales, verification of difference in result values due to differences in spatial resolution, improvement of CN(Curved Number) suitable for the research site conditions based on actual data, and development of flood damage factors suitable for domestic condition for the calculation of economic loss.

전 국토에 대한 난개발을 방지할 목적으로 2002년부터 시행되고 있는 토지개발허가제는 재산권 제한의 한 유형으로서 의의가 있지만, 전통적으로 이해하고 있는 토지소유권의 내용에 대한 수정도 불가피하게 하고 있다. 그리고 토지의 개발금지를 해제하는 것은 토지개발의 자유를 회복하는 데 그치는 것이 아니라 토지개발권을 형성하는 원인으로 해석될 수 있으며 이를 물권(物權)으로 발전시켜야 한다는 것이 이 논문의 취지이다. 개발행위허가를 재산권 제한의 한 유형이라는 점에서 보면 헌법상 그 제한의 근거와 보상요부 문제가 발생하게 된다. 그러나 그 제한은 개발행위허가를 통하여 회복되거나 완화될 수 있으므로 보상 문제가 해소될 수 있다. 개발행위허가제에 의해 토지개발권은 토지소유권에서 분리되어 공유화되었으며, 토지소유권은 이제 토지의 현상이용권만 남아 있고 장래의 현상변경권은 원칙적으로 가지고 있지 못하므로 전통적인 토지소유권 개념의 수정을 불가피하게 하고 있는 것이다. 토지개발허가제는 토지소유권의 권능에서 개발권을 독자적인 권리로 분리할 수 있는 성질이 있어야만 그 정당성이 부여될 수 있다. 만약 이러한 성질이 없다면 토지개발허가제는 토지개발권의 사회적 필요성을 충족하지 못하고 토지소유권 제한이론의 범주에서 그 논의를 벗어나지 못할 수 있다. 현행 "민법"이나 토지규제법 체계 하에서 토지 개발권을 물권으로 일반화하기는 여러 가지 어려움과 한계가 있을 것으로 보인다. 따라서 사회법이념의 토지기본법을 제정하여 재산권이나 물권이론에서 토지권 이론을 특성화하고, 이곳에서 토지개발허가제나 개발권 이론을 독자적 체계적으로 연구 발전시켜야 할 것으로 생각된다.

The purpose of this study is to find a way to improve damaged forest in rural area in terms of both landscape . quality and regulation. Mountain and forest cover 65% of total land in Korea, and the shortage of areas for developing housing, road and facilities made us to use forest area for above purposes. This led various types of damages on the sensitive rural landscape visually and ecologically. There are rules and regulations for decreasing damaging effect by constructions on forest area, but it was not so effective because theses rules focused on quantitative issues only. This study will consist of three phases, 1. analyse landscape damage types by development tendencies in forest area 2. find diminution plan on each damage types 3. set improvement on rules and regulations both qualitatively and quantitatively. This study will meet the goal of improving and managing rural and forest landscape by providing objective standards, rational procedure and amelioration plan.

이 연구의 목적은 토지적성평가를 기개발된 도시지역에 적용하는 것이 평가의 근본 목적에 부합하는지를 검토하여 제도 개선안을 도출하는 것이다. 이 연구에서는 서울시 환경 생태적·물리적·공간적 특성을 정리하여 입지현황, 수립현황 등의 내용적 특성을 검토한 후 선택지표를 적용한 토지적성평가 시뮬레이션 분석을 수행했다. 서울시 내 토지적성평가의 적용대상인 녹지지역에 대한 토지적성평가 시뮬레이션 분석 결과 모든 토지에서 개발성향 결과가 나왔다. 또한 도시지역에 적용할 경우 지역적합성이 반영되는 선택지표와 별도보전지역 지정에 따라 정성적 평가를 추가할 수 있는 장치가 있지만 이러한 선택지표 및 정성평가를 추가한 시뮬레이션 분석에서도 대부분의 녹지지역이 개발성향으로 분류되었다. 이는 서울시에서 도시계획적 차원에서 보전지역으로 관리하고 있는 녹지지역의 성격과 배치되는 결과이며, 그 이유는 전체 평가대상 토지의 적성값 평균과 표준편차를 이용하여 표준정규분포곡선상의 표준화값으로 변환하는 방식의 토지적성평가에서 적성등급의 비율이 가지고 있는 구조 때문이다. 따라서 기개발된 도시지역은 토지적성평가 수립에서 제외하는 등 관련 규정의 재정비가 필요하다.

Agricultural or rural landscape provides various ecosystem services. However, the ecosystem services function is declining due to various environmental problems such as climate change, land use change, stream intensification, non-point pollution and garbage. The A1B scenario predicts that the mean air temperature of South Korea will rise $3.8^{\circ}C$ degrees celsius in 2100. Agricultural sector is very vulnerable to climate change, so it must be thoroughly predicted and managed. In Korea, the facility horticulture complex is 54,051ha in 2016 and is the 3rd largest in the world(MAFRA, 2014). Facilities of horticultural complexes are reported to cause problems such as groundwater decrease, vegetation and insects diversity reduction, landscapes damage and garbage increase, compared with the existing land use paddy fields. Heat island phenomenon associated with climate change is also accelerated by the high heat absorption of horticultural sites. Therefore, we analyzed the heat island phenomenon occurring in the facility of horticultural complex in Korea. As an improvement measurement, I examined how much air temperature is reduced by putting the channel and the open space. In the case of the Buyeo area, the Computational Fluid Dynamics (CFD) simulation was analyzed for the average summer temperature distribution in the current land use mode at $38.9^{\circ}C$. As an improvement measurement, CFD simulation after 10% of 6m water channel was found to have an effect of lowering the summer temperature of about $2.7^{\circ}C$ compared with the present average of $36.2^{\circ}C$. In addition, CFD simulations after analyzing 10% of the open space were analyzed at $34.7^{\circ}C$, which is $4.2^{\circ}C$ lower than the present. For the Jinju area, CFD simulations were analyzed for the average temperature of summer at $37.8^{\circ}C$ in the present land use pattern. As an improvement measure, CFD simulations after 10% of 6m water channel were found to have an effect of lowering the summer temperature of about $2.6^{\circ}C$ compared to the current average of $35.2^{\circ}C$. In addition, CFD simulations after analyzing 10% of the open space were analyzed at $33.9^{\circ}C$, which is $3.9^{\circ}C$ lower than the present. It can be said that the effect of summer temperature drop in open space and waterway has been proven. The results of this study are expected to be reflected in sustainable agriculture land use and used as basic data for government - level policy in land use planning for climate change.

The objective of this study was to assess the effect of policies on water quality management based on the changes in pollutants and water quality in Special Water Preservation Area (SWPA) of Lake Paldang watershed from 1990 to 2016. The population, total sewage and flow rate of wastewater in SWPA continuously increased from 1990 to 2016, while the location of new facilities for industrial and livestock facilities has been restricted. However, unlike the buffer zone in which industrial and livestock facilities were continuously reduced after implementing of TMDL, it was found that the effect of land-use regulations on industrial and livestock facilities in SWPA were mitigated by the increase in the size of large facilities. Since 1999 when the emission standard of public sewage treatment plants (STP) was changed, the water quality of Lake Paldang has increased despite the increase of pollutant source. Since emission standard of STP changed in 2012 (BOD 5 mg/L, TP 0.2 mg/L), BOD concentration in Lake Paldang has also improved to the level of water quality in the early 1990s where as TP concentration has remained at its lowest since 1990. BOD and TP average discharge concentration of 43 STP (${\geq}500m^3/day$) in 2016 have been maintained $1.7{\pm}0.7mg/L$ and $0.06{\pm}0.02mg/L$ respectively. While the discharged load of STP in SWPA was decreased by the concentration management, the contribution rate to the total discharged load of non-point pollutants increased to 70 % in 2015, and the contribution rate to the point discharged load of individual treatment facilities increased to 80 %.
