The purpose of this study is to employ a method called 'conflict impact assessment' to analyze the progress, background, cause and relevant issues of conflicts related with affordable housing for youth (Happiness Housing Project), a project that has been implemented since last May 2013, thereby identifying the relevant problems and draw out objectives for improvement. The researchers expect that this study will contribute to solving the current issues regarding Happiness Housing, and contribute to improving the quality of the government's policies. For the above purpose, literatures on Happiness Housing produced from August to November 2013 were reviewed, in-depth telephone or face-to-face interviews were conducted with personnel associated with project implementation in the Ministry of Land, Infrastructure and Transportation and LH, etc., and major interested parties including Yangcheon-gu residents. Key issues identified regarding Happiness Housing construction include: the way that the project was implemented, living quality of residents, impact on educational environment, inconsistence with existing plans, relatively high construction cost, insolvency of public corporations, land use fee issue with Korail, need of preliminary feasibility survey, securing sufficient amount for supply and issue of additional designation, likelihood of finishing construction in time and issues related with actual source of demand, etc. Through analysis of conflict development and positions of interested parties, the main causes of the conflicts were identified as follows: lack of deliberation on pledges during election, lack of viability review on pledges, lack of conflict management plans, one-way implementation without consent of interested parties, project plans established with no regard to local circumstances, frequent project revision, underwehlming level of conflict management. In order to address issues above, the following measures need to be taken: selecting election pledges based on actual effectiveness, thorough assessment on pledges by relevant departments, gradual implementation based on consideration of the actual circumstances, participation of key interested parties, consistent policy and adopting conflict management techniques that reflect the reality.

The purpose of this study is to derive institutional improvement methods for promoting the Damaged Area Restoration Project in greenbelts. The current status of greenbelts in Gyeonggi-do, where greenbelts are extensively distributed was analyzed, and the relevant laws and regulations were reviewed to suggest measures to promote the restoration project. The area of damaged areas within greenbelts in Gyeonggi-do was 6,121,024 m², accounting for about 0.52% of the total area of greenbelts, and more than 80% was found to be located in Namyangju (55.49%), Hanam (16.48%), and Siheung (8.68%). Various measures to improve the policy were examined as follows: reducing the minimum size of the restoration project area; adjusting baseline of recognizing range of damaged areas; introducing the right of claim for land sale; allowing long-term unexecuted urban parks to be replaced as alternative sites for parks and green spaces; simplifying administrative procedures; and allowing public participation. All of them are expected to promote the restoration project within greenbelts. In results, when the minimum size of area for the restoration project was reduced from 10,000 m² into 5,000 m², 3,000 m² and 2,000 m², the ratio of the number of combinable lots to the total number of lots increased from 4.4% to 18.8%, 38.8%, and 55.9% respectively in Namyangju. Morever, when the recognizable ranges of the restoration project were extended to the structures obtaining building permit as of March 30, 2016 and obtaining use approvals before December, 2017, the number of applicable lots increased by 5.1% and 9.2% respectively.

Recently, one of the critical issues in Korea is the huge debt and future role of Korea Land and Housing Corporation. In this regards, the purpose of this study is to get implications from other public housing agencies in Asian countries such as UR of Japan, HDB of Singapore and HA of Hongkong. The changes of housing policy since 1960s, business and financial structure of housing agencies in each nation are investigated and compared. As a result, some policy directions can be proposed as follows : review of current mass housing program, relaxing qualifications for public rental housing, promotion of urban renewal projects, reinforcing cooperation with private sector and local governments, more government's support to LH's financing and loss from businesses for public interests and re-evaluation of LH's debt. The contribution of this study is that suggestions to improve housing policy and to alleviate financial problem of LH are based on the actual conditions of public housing agencies in Asian countries where the housing policy implementation system is similar to Korea, not on the theoretical basis.

SWMM-LID was calibrated with flow monitoring data in LHI to evaluate runoff after LID application. The flow rate in the B basin was estimated to be 0.94 and 6.15 for O/S and $D_v$, respectively. In the A and C basins, the difference between the observed and simulated data was greater than in the B basin. As a result of runoff reduction efficiency by the application of LID facilities, the change of infiltration increased from 34.6 % to 45.8 % in the entire watershed, and the runoff decreased from 58.8 % to 46.3 %. In the runoff reduction of each LID facility, rain garden E showed the highest effect with 99.9 % and bioretention B showed the lowest effect with 27.5 %. In order to evaluate the efficiency of each LID facility, a comparison is made between the pore volume (V) of the LID and the catchment area (A). The runoff showed a runoff reduction effect of about 70 % above the 0.1 volume/area (V/A) value. As a result of examining the runoff reduction with LID facilities by the LID module of SWMM, a reasonable design is possible by reflecting the appropriate LID volume to drainage area.

One of the problems associated with the current system of land development projects implemented by the public sector in Korea is that various service facilities are not ready in time for the occupation of residential dwelling. A major cause of the problem is the lack of financial arrangements which would smooth the cash-flow of the suppliers of the facilities during the project period. In this paper we present two schemes which will contribute to the optimal provision of service facilities by easing the financial constraint facing the land developers and suppliers of the facilities. The first scheme involves channeling a fraction of profits from a land development project and of the proceeds of mandatory sales of Type II National Housing Bonds as a loan to the suppliers of the service facilities. The second scheme considers the participation of the private sector in the project as a member of a consortium comprising the Korea Land development Corporation, the National Housing Fund, and private developers. It is proved that each scheme is superior to the current system. as well as entailing a very small cost.

At the Korea Land and Housing Corporation(LH), concretes with high design strength of 50 MPa and 80 MPa that are composed only of ordinary Portland cement, blast furnace slag, and fly ash are developed. To determine whether the developed high strength concretes have the same properties when they are produced in batch plant(B/P) condition in the ready mixed concrete plant, and as existing high strength concretes, field tests are performed and material properties are evaluated. To investigate the material properties of the high strength concretes before and after pumping, compressive strength, flowability, air content, hydration temperature, pumping and compactability are evaluated. In field tests, before and after pumping, flowability satisfied the relevant criteria. In terms of air content, while it was slightly decreased after pumping, it satisfied the requirements. Hydration temperature criteria were satisfied, and compactability was excellent as well. The study found that the developed ternary high strength concretes have the same properties as existing high strength concretes. They can also be useful for the construction of high-rise buildings, as they are economical.

In era of lowbirth, aging population, low growth and social polarization, the effective welfare delivery systems are taking on added significance than past years. Public housing welfare resources, such as public rental housing, housing voucher, affordable housing loan, are more diversified and expanded. These programs could work effectively by the comprehensive interlink and community based delivery system. From the standpoint of recipients, how effectively the substantial benefits of welfare resources being delivered to each individual is more important than how much welfare resources being produced totally. This study aimed to explore the reform of public housing welfare delivery system. For this purpose, diagnosed the current states and key issues related to public delivery system, and analyzed what kinds of housing welfare services should be strengthened, and finally suggested the collaboration among the public sectors (local government, LH, HUG, HF etc.) and the partnership with non-profit organizations. Main research implications are as follows. The main housing welfare services which could be categorized as the housing welfare center's role are advice & information offering, several public resources interlink and accessibility improvement, community based network construction, etc. And the most important key for successful delivery system reorganization is the collaborative operation of the public sectors and local government, non-profit organizations.

Colombia experiences a population growth in their metropolitan areas through an accelerated urbanization process, a housing deficit and a shortage of urban developable land. To solve these problems, the central government developed a national policy for a large-scale housing city development including supra-municipalities planning instruments such as Macroprojects. However, the amount of housing land supplied by this policy is insufficient and additional policies for shortage housing and qualitative deficit are required, particularly in regions with a high concentration of population. The purpose of the study is to compare urban development systems of Colombia and Korea and explore the possibility of applying guidelines to Colombia through i) comparing the capital region cities of the two countries with an asymmetry context method, ii) comparing both urban planning system founding similarities and differences, and iii) suggesting new urban development challenges in the Bogotá metropolitan area based on Korea's new town experience.

This study is to identify quantitatively the function of carbon dioxide emissions reduction due to temperature and energy reduction according to direct carbon dioxide storage, shade provision, and evaportanspiration of urban park. According to the result of study, landscape tree indicated high carbon dioxide storage effect compare to bush, in which broadleaf tree indicated higher storage function than coniferous tree. It is believed to be the storage of carbon dioxide can be increased by increasing the composition rate of forest plants in the urban park. According to the direct estimation result of carbon dioxide storage in terms of example area, storage of carbon dioxide is estimated to be "seoul a zone" $476,818.8kg{\cdot}CO_2/m^2yr$, "anyang b zone" $186,435.7{\cdot}CO_2/m^2yr$, "daejeon c zone" $262,826{\cdot}CO_2/m^2yr$, "kwangju d zone" $231,657.8{\cdot}CO_2/m^2yr$. The carbon dioxide storage per unit area estimated to be "seoul a zone" $3.4{\cdot}CO_2/m^2yr$, "anyang b zone" $5.0{\cdot}CO_2/m^2yr$, "daejeon c zone" $2.6{\cdot}CO_2/m^2yr$, "kwangju d zone" $5.6{\cdot}CO_2/m^2yr$. The result of indirect carbon dioxide reduction effect estimated to be "seoul a zone" $291,603.4{\cdot}CO_2/m^2yr$, "anyang b zone" $165,462.4{\cdot}CO_2/m^2yr$, "daejeon c zone" $141,719.2{\cdot}CO_2/m^2yr$, "kwangju d zone" $154,803.4{\cdot}CO_2/m^2yr$. Carbon dioxide reduction potential amount through the urban park was increased to 1.6 times to 1.8 times when calculated to the indirect effect.
