The amount of construction waste increased to 176,447 ton/day in 2008 from 28,400 ton/day in 2000, a 6-fold increase in just 10 years. Such dramatic increase in the waste of concrete, asphalt concrete, wood and metals was due to demolition of old buildings as well as a great number of building redevelopment projects and hurried city industrialization. Many buildings targeted for demolition today were built in line with the government policy to provide affordable housing to citizens in the shortest time possible and consequently, said buildings underwent rapid deterioration and required periodic repairs and reconstruction. Based on the above, we predict that construction waste will continue to increase for the foreseeable future. In particular, due to limited availability of suitable space to construct apartments and residential buildings in the city, old buildings are being torn down to make space for new development, further increasing construction waste. In light of that, efforts to recycle as well as reduce generated waste are urgently required.

As many stakeholders are taking part in the Housing Redevelopment Project, their opinion mediation is considering very important issues. Thus disputes on projects are inevitable due to complexity of interest. To effectively progress the project, this paper analyze the risk factors by phase in implementation phase that the association participates in person. We identify 50 of risk factors in implementation phase by reviewing and analyzing related studies and actual cases of disputes, then we present 26 of risk factors through experts interview. Also, we calculate weights of risk factors by using AHP for quantitatively analyzing them and present final weights and priorities of risk factors by summing weights of risk factors by phase. In results, it is found that 'the inappropriateness of the Management Disposal Plan' in management disposal plan phase and 'the inappropriateness of the Project Implementation Plan' are the most significant risk factors. To maximize the utilization of risk factors analyzed, we present the checklists that can be aware of these risks in advance and prevent these risks. Based on these findings, if risk factors in implementation phase are managed actively, the housing redevelopment project will be performed more effectively.

This study tries to promote an effective use of semi-public space of urban street in social point of view. The main results are follows. First, semi-public space is occupied by private users and it makes urban landscape unrecoverable. The real problem is that people do not know the space is for public use rather than pure private use. Second, the standard of semi-public space requirement should be changed from floor space to lot area. In addition, the standard should apply to buildings on an area less than a legal standard. Third, some ways of attaining the semi-public space in relation with adjacent lots should be introduced in the case of urban redevelopment nad living condition improvement projects.

The purpose of this paper is to highlight the main policies of the last half century that have shaped the urban architectural fabric of Seoul today, and explore whether a modified approach might better address the current socioeconomic conditions in Korea. The paper defines and examines urban planning in Korea through an overview of the four main urban project policies implemented in Seoul from the 1960s to the present: Land Readjustment (LR), Housing Site Development (HSD), Urban Redevelopment (UR), and Housing Reconstruction (HR). While the fundamental ideology behind these policies served well during a prolonged period of high economic growth, evidence is growing that these policies are losing steam under today's conditions. A growing legacy of stalled and incomplete urban projects from the mid-2000s-the New Town Project is an example-begs the fundamental question as to whether an alternative urban planning paradigm is needed for Korea in an age of low economic growth, low birth rates and a fossil fuel energy crisis. Through the urban morphologies of the three residential areas in Seoul developed by LR projects, this paper looks at the possibility of urban regeneration through the sustainment of urban architecture in those residential areas that have not been affected by HSD, UR, and HR.

Urban renovation projects (reconstruction and redevelopment) have a longer licensing period than general housing projects, and many consultations with the licensing authorities require expertise. Most of the members of the union do not have basic knowledge of the maintenance business, so they have a lot of authority to promote smooth business Is entrusted to the union leader. However, contrary to the original purpose entrusted by the members, it is easy to find a case where the business is suspended because the union leader is exposed to corruption for the private interests of the union, and the members' disputes could not be resolved. In order to overcome this risk, the problem of the maintenance project was found through a questionnaire survey composed of practical experts, and a solution was presented through the KCSI evaluation model. This study mentioned the necessity of a responsible CM that can make independent business decisions without interference from the union, rather than a management-type CM limited to the cooperative's work assistance. In order to promote the construction industry's national role, it was necessary to revitalize responsible CM, so six practical alternatives were proposed.

Urban space structure in South Korea when through drastic changes ever since public housing policies began their full-fledge implementation. That is, public housing policies represent the main cause for formation of the current urban space structure, as the public houses are constructed in accordance with changes of demographic/social structure, considering changes of housing demand, in urban spaces demanded by the end users. After rapid industrialization and urbanization in the 1960's, each government in different periods have implemented housing supply policies through massive urban developments, to resolve the issue of housing shortage and residential instability. Phase 1 New Towns were developed in the 1980's resulting in suburbanization of the Seoul Area, followed by urban sprawl due to construction of small-size New Towns after deregulation in the 1990's, and construction of Phase 2 New Towns for resolution of housing shortage in the early 2000's and the resulting urban problems. In the mid-2000's, construction of Bogeumjari houses in GB areas led to insufficient housing supply in downtown areas, and the period after 2010 witnessed continuous deterioration of existing urban areas and acceleration of the rental housing crisis caused by rental housing shortage in downtown areas. Moreover, the residentially vulnerable classes consisting of young, 1~2-member households is expanding, with the real estate market in recess. Therefore, the government is trying to achieve urban regeneration through public housing policies so as to resolve the urban space problem and the housing problem at the same time, and the Happiness Housing Project has been implemented as a policy to achieve that goal. The Happiness Housing Project for young, residentially vulnerable classes in downtown areas, is going through diversification aimed at conjunction with urban regeneration projects in downtown areas, as exemplified by conversion of rental houses in residential environment improvement project districts and redevelopment/reconstruction project districts into happiness housing, and supply of happiness housing in conjunction with small reorganization projects for deteriorated residential areas in such areas as those excluded from New Town designation. Continuous supply of Happiness Housing in conjunction with urban regeneration requires mixed-use residential development which includes convenience facilities and public facilities, along with improvement of rental conditions (rental period/rent) and diversification of project methods, considering that the project is implemented in downtown areas.

As that experienced in other developing countries, Mongolia has already faced multilateral side issues for two decades due to economic growth that created Ger areas or internationally 'Slum', public housing and living conditions for low-income citizens, on the basis of rapid migration from rural areas to urban. Ger areas appear to be the main cause of environmental pollution problems and impending comfortable living conditions of the city's residents by covering more than half area of Ulaanbaatar city. Also, the spread of the Ger areas has many side issues such as prevention of urban development and unaesthetic. Most inhabitants of the areas are on low-incomes, and living in the detached houses or felt yurts (Ger) usually build within a low budget, by themselves or unprofessional people, and by using materials of poor quality. Therefore, Ger areas are an inevitable issue that requires effective, proper and immediate housing policy coordination under the government and even the housing market. Unfortunately housing policies, laws, and projects adopted by Mongolian government have shown inefficient results. The government housing policies, unlike other developing countries did not target low-income households' housing which is the priority issue for two decades. But only in 2014, the Long-term housing policy with the strategy for affordable housing initiated the housing policy for low-income households. This policy has five main broad directions such as redevelopment of Ger area, the land readjustment, public rental housing, new settlements and new city and reconstruction for old apartments, which are rather general and would require tremendous financial resources if each of the directions is implemented simultaneously without prioritization. Therefore this research aims to suggest the efficient and adequate housing policy direction for the low-income households in Ger area based on achievement of other developing countries' strategies, performances and generic characteristic with explanatory models. Also, this research adopts a literature analysis method that uses various research reports, related papers in domestic and international journals, and theses by experts, researchers, public institutions, and agencies.

An increasing number of cities employ rescaling strategies that not only construct metropolitan production network scaled down from national context, but also tune up new governance to effectively control local geographies of the city. In this context, urban redevelopment has emerged a key 'global' strategy to empower governmental institutions of the city, which not only eliminate such threatening spatial variables as deteriorated housing, working-class ghettos, and crime areas, but also increase and extract exchange value of those spaces. I view such practices a process of 'glurbanization'. This paper investigates how state/city government employs the discourse of urban re/development for 'inventing' poverty at an urban scale: how it institutionalizes the discourse for implementing concrete projects: and how urban institutional apparatus appropriate their discursive practices of redevelopment for their own ends in the city. By particularly focusing on the California Redevelopment Law and the Community Redevelopment Agency of the City of Los Angeles, this paper analyzes the ways in which the law and the agency extract value from what they define 'blight areas' by means of eminent domain and tax increment revenues. For empirical analysis I employ discourse analysis and institutional ethnography. I conclusively argue that the urban spaces stigmatized as 'blight areas' are increasingly entrapped by the urban redevelopment agency, which extracts increased exchange value from the areas and redirects it for supporting external investors, private developers, and the body of the agency itself.

For the past few decades, residential improvement projects have been mainly carried out after demolition of the original dwelling place. So far, interests and opinions of the existing residents have largely been ignored during the projects. However, citizen participation in local redevelopment has recently been regarded as essential part as progress in democracy and diversified public interests have offered more importance to citizen participation in the implementation of public policies. While the importance of resident participation has been increasingly emphasized in principle, there still has been more to do in its application in reality. We should develop the experience of collecting community opinion to make them reflected in public policy, if we are to achieve the resident and citizen-centered society. The purpose of this study is to develop an image map tool that can be applied to "Maul-Mandulgi" projects as a visualized method to facilitate the exchange of opinions and work toward agreements. The tool is supposed to assist the public discussion by visualizing the policies and reducing the possibility of misunderstanding, so that residents can properly respond to them. In addition, this study will verify the effectiveness of the tool in the application to local community workshops.

This study is about the research of living environment in residential areas created by the land readjustment projects in the modern era, and recently lifted from Residential Environment Improvement district at the same time. The five criteria for evaluating the residential area are safety, health, convenience, comfort, and sustainability. The level of resident satisfaction in general is as follows. [completely dissatisfy as 5.30%, dissatisfy as 16.29%, neutral as 49.62%, satisfy as 16.29% and completely satisfy as 6.82%]. The results of the five survey items on the residential areas show that residents are aware of the area not as an old residential area to be demolished, but as a comparatively excellent residential area, namely very different results from the designation criteria of the redevelopment area designated by the Urban and Residential Environment Improvement Act. If the road conditions and the deterioration of the buildings are judged to be designated as the redevelopment area and to be removed these settlements, the residential areas with social sustainability could demolished. Based on this study, it is necessary to conduct the research to find out the reason for deriving the results of each evaluation item in the succeeding study. These studies are needed to rediscover, to develop and manage the value of many old residential areas scattered in the city centers of local areas.
