This study aims to figure out the effectiveness of low-carbon oriented residential regeneration by on-site improvement method. For this, we examined some technical planning elements for carbon reduction and selected standard criteria of computation on energy use-based amount of carbon emission through previous literature review and case studies. Next, based on this, we compared and analyzed three types of carbon emission in the designated renewal area in Cheongju City. The three types of carbon emission were the existing development, the redevelopment of apartment by overall removal, and the development of low-carbon oriented residential regeneration by on-site improvement method. Finally, we examined proper way to reduce carbon emission in low-carbon oriented residential regeneration.

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.

Necessity of paradigm change has been awared in urban redevelopment especially, in housing regeneration from uniform scratch without serious consideration about resident's lives to holistic approach based on local culture and residents' participation. The purpose of this research was to identify community places recognized and attached by residents of a housing improvement district which was scheduled to be changed for improvement of the area, in near future. This research itself was considered as an resident participation technique. Group interview at a field site was carried as the main research methodology. As results, valuable places cherished by residents were identified. Most of them could be explained in relation to religious leadership, traditional cultural heritage and democratic movement. In regeneration process those places which have a strong tie with residents needs to be deliberately considered as a target to be preserved rather than demolished. The places also play a role in diffusing a livable village making movement. The result is expected to be used to make a cognitive and emotional community map of residents which is meaningfully differentiated from just a physical and geographical map. The places, place recognition activities and diffusion movement for common appreciation can be a basic foundation for residents participation in improving their housing neighborhood environment, and in creating value added strategies for the area.

The population of Daegu, the third biggest city in Korea, is two point six million. Daegu is known as a basin or a city where it is not only too hot in summer but also too cold in winter. Recently with redevelopment apartment house boom, a 40-story or more apartment complexes are under construction near Shin-cheon and Dondaegu-ro, the south-north axis of Daegu. It is necessary to raise several points about blocking a road of the wind by high-rise apartment buildings and apartment complexes. As a kind of the green policy, Daegu enlarge the distance between apartment building by reconstructing low-rise apartment into high-rise and impose a duty of a green space on the ground by making a parking zone into an underground. Through this process, apartment complexes changed from a '一'shape to a '口'shape. It increases heat island phenomenon of a city by blocking a road of the wind that comes from Shin-cheon and Dondaegu-ro. To circulate the polluted air of Daegu basin, we need local wind. There are four effective measures. 1) Throw three greens into one in the center of the road at the north side in the same way of the south side of Dongdaegu-ro, 2) reflect the information of roads of the wind including heights, spaces and directions of buildings, 3) steer clear of a high-rise buildings and development apartment house constructions, and 4)select a city for benchmarking to be the environmental capital.

The trend of current urban redevelopment and new city development project shows that the superstructure of building is getting larger and higher in consequence of a limited plottage condition and the preference of landmark. For this reason, it is definitely required to extend pile diameter and install the pilein deep foundation to support superstructure. The pile method causes construction-related problems such as increasing quantities, difficulty of storage & transportation material and decreasing design load while construct pile in deep foundation. The Bored Pile method has applied to minimize those problems. As above shown, this article will be presented construction case study of Barrette Pile and R.C.D in order to make a counterproposal for the quality control of a large building foundation work.

In recent years, many high-rise buildings have been constructed for the purpose of redevelopment of urban environments in Korea. However, generally the construction durations do not increase in proportion to the number of the floors or the height of the building. So new materials, equipments, and methods are applied to high-rise building construction in order to overcome this problem. In most cases, applying these new resources is considered mainly as the technical issue, and the organizational aspects of this is frequently overlooked. This study discussed the performance variance in time and identified the causes of time variance in high-rise building construction from organizational viewpoint .

While there has been a substantial amount of studies on public rental housing of Korea, most have focused on housing policy changes, international comparisons, and current characteristics and future prospects. This article aims to examine the evolving roles of the national and local governments, and the private sector in provision of Korea's public rental housing. The findings suggest that one, although the wave of neoliberalism and financial crisis have prompted the national government to reduce its role and to encourage engagement of other actors by utilizing incentivizing tools, it has continued to assume a central position in formulating and implementing housing supply plans. Two, local governments have played a marginal role throughout the history of public rental housing supply, although they have expanded their participation through redevelopment projects and utilization of existing housings. Three, private sector actors have expanded their role to delivering public benefits of making housing available for a wider range of populace leveraging various incentives that make projects financially more feasible. The study poses a question on how responsibilities and risks can appropriately be allocated among three key actors to achieve housing welfare going forward.

A Soil Nail is a structural element which provides load-transfer to the ground in excavation reinforcement applications. The nail may simply consist of a steel tendon, but most commonly the tendon is encapsulated in a cement grouted body to provide corrosion protection and improved load- transfer to the ground. For temporary excavation support in a congested urban area, the steel bar of Soil Nails should be removed to get permission of the private land to install Soil Nails. Several removable nail systems were developed and evaluated by pull-out load tests. The Soil Nail pull-out tests were performed on five nails installed in soft and hard rock at a 00 housing-redevelopment area in seoul. Two nails are plastic socket type and two are complex socket type mixed steel and plastic. The nail was 0.1mm in diameter, 4m long. In this study verification tests, and steel bar removing tests of plastic socket type nails and complex socket type nails were performed and presented.
