Massive migration is underway in rapidly urbanizing Guangzhou, the south gate of P. R. China. Over half the migrants choose to rent in "villages-in-the-city" in the downtown area because of the low-cost and prime location. The overpopulation and resulting poor environment and high crime-rate turn villages-in-the-city into de facto ghettos. As a result, these ghettos are undergoing a manner of demolition-development, leaving migrants' housing needs unmet. A private-sector initiative-the Tulou Commune-intends to address this considerable market potential. Targeting low-income groups, the Tulou Commune creates a socio-spatially exclusionary enclave. This paper analyzes the Tulou Commune and the implications if more low-income migrants shifting from village-in-the-city (excluded ghetto) to Tulou Commune (exclusionary enclave). This study argues that the intervention of the private sector causes the demographic, social, and spatial similarities and differences of the two living arrangements. Socioeconomic and institutional factors also affect the initiative. This study also provides more empirical evidence in the field of low-cost housing and socio-spatial development in transitional Chinese cities. As the first project of its kind, the analysis of the case can suggest how to improve strategies for accommodating migrants in the future.

The indices to choose the object countries for developing overseas industrial park were developed and applied in this paper. The results are showing as follows. First, the Korean enterprises are branched out into total 128 countries as of the first quarter of 2010, and the 13 asian countries including China, Vietnam, Japan, and Hongkong shows the majority of precedence 20 countries among the reported during 1980-2010. Second, the 3 steps of selecting the principal region to branch out, establishing assessment indices and criteria, and choosing strategical target counties were developed to choose the countries for developing overseas industrial park. The 38 of 128 countries were selected where the GDP per capita is lower than Korea, and the local reports of incorporation during 2007-2010 are more than 10 times. Then, the 10 countries were excluded where the minimum wages during 2008-2009 are similar to Korean ($815/month). Consequently, the 28 countries including China, Vietnam, and Cambodia etc. were selected as the major target regions. Third, the indices to choose countries for developing overseas industrial park are classified into 5 categories-investment condition, labor market flexibility, potential market demand, population, changing rate of the reported number of manufacturing industry, and detailed indices for each category were selected, then the weight were given with the consideration of importance. Finally, Indonesia, Mongolia, and Uzbekistan were selected as the strategical target counties where acquire the high score in labor market flexibility and investment condition, relatively undeveloped, and friendly to Korea.
The Effects of Apartment Brand Image Characteristics on Purchase Intention

There have been a lot of previous studies that brand image has a positive impact on purchase as well as the value enhancement of the product with the spread of brand importance and the introduction of brand in the apartment. This study verified that brand image can be factorized and separated into two factors - basic characteristics and additional characteristics. The basic characteristics means essential parts that generally should be provided for housing and the additional characteristics are competitively developed concepts introduced by construction companies for sales promotion. The results of the empirical analysis that verified the effects of the two factors on purchase intention are as follows. The basic characteristics have the positive impact on purchase intention while the additional characteristics are otherwise. This result suggests that it is more important to be faithful to the basics than to be competitively differentiated by the additional characteristics in the apartment market.

This study aims to introduce "Street-Housing" Redevelopment Projects adopted by the revision of regulations in 2012 and promote them by surveying residents' needs. The objectives of the street-housing redevelopment projects are to maintain existing street systems and redevelop housing by small units, as an alternative to the large-scale housing redevelopment by the expropriation. Residents, however, do not seem to support the new projects since they are satisfied with their current housing, have difficulty in raising funds, and are uncertain about proceeding with the pre-arranged. Despite these barriers, residents may support the projects if project charges can be lowered by the reduction in each resident's share and the increase in supporting funds. This study proposes new practical methods for realizing the projects: choice of an appropriate site, engaging for resident's participation in projects, reduction in project charges, and removal of barriers to co-operative development. etc.

This paper defined the concept of unsold land and diagnosed the cause of unsold land of LH business site. The results are showing as follows. First, unsold land is defined as land could not be sold until the completion of the project, and plan to sell the unsold land can be changed partially. Second, the status of unsold land in the 226 project sites were analyzed.
area corresponding to 74.8% of the total capital area(
) are unsold. By purpose, co-residential(
), exclusive residential(
), commercial business(
) was larger in order. Third, value enhancement target project sites were selected and its symptoms and the cause of unsold land were analyzed. For the project site over average unsold rate, 6 sites located in province and 2 sites located in capital region were selected through collecting the practitioners and expert opinion. These 8 sites are characterized that sale of land for medium and large co-residential, urban support facilities, block-shaped house and attached house was inactive. Also, these sites commonly experienced economic fluctuations, changes in market demand, supply and demand mismatch, inflexible planning standards.
3D Finite Element Analysis of Lateral Loaded Pile using Beam and Rigid Link

The BNWF (Beam on Nonlinear Winkler Foundation) model is one of the simplest idealizations for a pile embedded in soil as it ignores the continuity of the soil. This method is difficult to model the behavior of pile group foundation subjected to lateral loading. The limitation can be overcome with the utilization of the finite element method (FEM) or finite different method (FDM) to represent a pile element embedded in a soil medium. Both the ground and piles are modeled with soild elements. The solid elements, which do not have rotational degree of freedom, is not appropriate for modeling piles. It can be overcome by substantially increasing the number of elements, which can be prohibitive for 3D modeling. This paper used the beam element and rigid link incorporated in the OpenSees to model the pile. The accuracy of the model is validated through comparison with lateral load test and BNWF analysis. It is shown that the method can capture the measured behavior accurately. It is therefore recommended to be used in group pile analyses.

Driving a prefabricated pile is the efficient construction method with low cost and excellent bearing capacity charateristics. But pile drinving method has often been changed to bored pile method with mechanical boring due to the unexpected problems occurred in the various domestic ground condition with landfill. So, pile driving method has more uncertainty than the Bored Pile method. This paper proposed LRFD design value which is one of limit states design method for the PHC driven pile used as building foundation to guarantee the reliable design with reduced uncertainty. This paper analysed 221 dynamic load test results(E.O.I.D : 93, Resrike : 128) and the different methods of estimating bearing design(Meyerhof method & SPT-CPT conversion method), and proposed LRFD value for each design reliability Index 2.33 and 3.0 for PHC driven pile. LRFD value of PHC driven pile represents 0.43~0.55 for Meyerhof method and 0.40~0.49 for SPT-CPT conversion method according to the deign reliability index.

Energy saving strategy for public housing is given a sizable portion in Land and Housing corporation. From this reason, the consumer's characteristics and energy consciousness of public housing dweller was derived from field survey for compare with sale housing residents characteristics. Utilities fees (e.g. gas and electric) for public housing residents was about 50 percent of sales housing dweller, but real energy consumption was accounting for 70% of sales housing residents in electric consumption. Among the respondents for public housing dweller up to 80 percentile of end-user comment that they have less demanding utilities fees. Given the major energy saving strategies, such as install EMS, make a teaching tool for children, sale housing residents is more proactive approach to participant energy saving strategies than public housing residents.

In this study, cases of domestic tall residential buildings were investigated for the structural types, numbers of stories, total heights, type of lateral load resisting systems, and zoning of concrete strength. Based on these investigation data, the structural planning pattern of tall residential building was analyzed. SRC structure is main structural types of tall residential building at the initial stage of domestic tall residential building, but RC structure is substituted for main structural types since 2005. Retaining wall system is positioned at the core part of structural plan as a lateral load resisting system. Concrete strength zoning of vertical members like columns are divided by vertical heights of lower parts, middle parts, and upper parts. Basic data of structural planning of 40stories and 60 stories residential buildings was proposed based on case investigation.
