This paper examines the characteristics and status of the major development policies for under-developed region by ministries and studies how the awareness or perspective of public officials on such policies impact the policy environment. This paper aims to redefine the goal and strategy of regional development policy so that it can effectively contribute to enhancing the quality of life of residents and improving competitiveness of the region. The problems and improvement direction found out through a documentational and practical research on the development policy for underdeveloped region can be summarized as follows: Firstly, more streamlined and integrated policies which are currently fragmented being implemented by different ministries are needed to enhance the effectiveness of policy execution. Secondly, improvements on the process of securing government funding and operating systems are needed to guarantee the rational standard of providing state subvention, the expansion of comprehensive subsidy and the independence of policy execution. Thirdly, amendments on the policy measures are needed to support the development and execution of the customized projects, strengthen cooperation among those projects by establishing a system for effective regional development project.

Recently multifaceted advantages of urban agriculture are emerging in civil society and related policy arena such as food safety, environment, and social welfare. This study tried an estimation of residents' willingness-to-pay for urban farming to examine feasibility of using part of urban green infrastructure as urban farm (e.g. allotment garden). A survey targeting Bundang and Dontan new-town residents was carried out and willingness-to-pay for urban farm rental was estimated by contingent valuation method (CVM). The estimated rent was cross-checked with the rental cost and travel cost paid by hobby farm users in the outskirt of metropolitan area. The result of this study showed that the potential demand for urban farming is ample if urban farms or allotment gardens are planned within new development areas. That is, 72.6 percent of new-town residents questioned had intention of using allotment garden within urban parks and green spaces. Estimated willingness-to-pay for renting a plot,
of urban farm, was about 236,000 won(KRW), which is higher than rent for a plot of allotment garden which is located out of city. Variables which were statistically significant to estimated willingness-to-pay for urban farming were sex, age, and occupation of respondents, among other explanatory socio-demographic variables, while expected frequency and duration of visit to urban farm were insignificant.

The importance of corporate social responsibility has been more highlighted recently for the sustainable management of the company. The purpose of this study is to empirically find out if the effects of CSR activities on public corporation are shown as same as they are on the private companies which have been verified in the previous studies. We set 'CSR activities' and 'Brand Image' to the independent variables and 'Corporate favorableness' and 'Purchase intention' to the dependent variables. The empirical analysis results are as follows. We have found that high positive causal relations are shown in 'CSR activities'
'Corporate favorableness', 'CSR activities'
'Purchase intention' and 'Brand image'
'Corporate favorableness', 'Brand image'
'Purchase intention'. Therefore just as product related 'Brand image' influences positively on purchase intention, the CSR activities have positive influence on product purchase intention and on the whole corporate image as well.
Land Bank Bond for the Diversification of Land Bank Financing Resources: Comparative Case Study and the Improvement of Legal, Accounting System
Lee, Jong-Kwon ; Choi, Eun-Hee ;
LHI Journal of Land, Housing, and Urban Affairs , volume 3, issue 4, 2012, Pages 333~341

The financial resources for public land banking enacted by Public Land Banking Act (2009) are LH (Korea Land and Housing Corporation) contributions, LH Bond, Land Bank revenues, etc. But, in real, the efficient funding resource is mainly LH bond. In these days, LH has experienced deep financial distress, and difficulties in issuing it's bond. Therefore, Land Banking project also has been inactivated because of poor financial resources. As Land Banking project depending its financial resources mainly on LH Bond does not have financial sustainability, it is necessary to reform the fundamental funding structure. This is the starting point for the topic of this paper. This paper suggests to reform the funding structure, and to introduce Land Bank Bond guaranteed by Government, and also to modify the accounting method of Land Bank to separate the Land Bank accounts with LH accounts. The funding structure reform can be summarized as follows; In early stage of the Land Banking project, sufficient government support by guaranteeing the Land Bank Bond is necessary. Gradually, the portion of LH's contribution can be increased in company with LH's financial distress being solved and administration being normalized. When the project reached on the stage of maturity, cash inflows by selling the reserved land can exceed the cash outflows for reserve new land. To introduce the Land Bank Bond guaranteed by government, the Public Land Banking Act (2009) should be revised. Along with this, to modify the accounting method of Land Bank, the rule for public enterprise accounting system must be partially revised.

Lee, Sang-Jun ; Yoon, Jeong-Joong ;
LHI Journal of Land, Housing, and Urban Affairs , volume 3, issue 4, 2012, Pages 343~355
DOI : 10.5804/LHIJ.2012.3.4.343
The purpose of this paper is to propose reasonable improvements of demand estimation methods of commercial site through the case study. Thus, we investigated the problems and limitation of demand estimation methods and process applied to primary and secondary new towns in Korea. And we suggested the way to reduce error of demand estimation and to raise its objectivity. The result of case analysis is as follows; firstly, it was insufficient to consider location, hierarchy and change of land use like mixed-use development in commercial site. Secondly, improper comparable group or operated relevant index data in the same light were selected the aggregated unit requirement method such as comparative analogy method and planning guidelines. Thirdly, there were many cases that demand estimation value was amended arbitrarily, and it tends to occur a serious reliability problem. Therefore, to improve these problems and to make better use of demand estimation hereafter are required the sublation of arbitrary commercial sphere's settings, the making of comparative group considered development conditions, and putting forward objective revision basis.

Jeong, Yeun-Woo ; Seong, Jang-Hwan ;
LHI Journal of Land, Housing, and Urban Affairs , volume 3, issue 4, 2012, Pages 357~367
DOI : 10.5804/LHIJ.2012.3.4.357
The efficient business scheme were suggested with the consideration of the local development condition at Ulaanbaatar. Major findings of the study were presented as follows. First, high level of education and the underground resources are presented as the merits of Mongolia. On the other side, the defects are limited domestic demands of 2.6 millions of population and the insufficiency of the infrastructure. The improvement of the infrastructures like roads, water & sewage, electric power, and heating is urgent while the development pressure of Ulaanbaatar is expected to be high due to the continuous inflow of population. Secondly, the Mongolian land system consists of the right of ownership, lease and use, therefore there are some differences among the right of land. Thirdly, definite business scheme to sell land in lots and to sell buildings in lots are suggested which are actual methods to participate in the development project in Ulaanbaatar. Moreover, enhancing the possibility to sell the lands, fixing the proper sale price to secure the profit, finding the proper buyer for the profitable lands, investing of quota and guaranteeing of granting the principal and interest by the Mongolian government, etc. are presented as consideration when participate in projects.

In France, there are many forms of organizations based on the intercommunal solidarity for city development and management. The purpose of the collaboration among Communes is to achieve high quality and well-equipped service-delivery system through co-operation of public services needed grand finances : water supply and sewage system and waste disposal system etc. The cooperation among French Communes and its effects, even though these were owing to the existing French local administration system, continued throughout regional co-management and social co-development process. This study suggested some characteristics and implications of the collaborative-style French new-town development and management organizations focused on the EPA, SAN and CA. First, the role of developmental corporation like EPA and its collaborative structure of decision-making are meaningful, because in these ways many related Communes could share a goal of new town development. Second, the way of new town corporation (SAN) is important in the sense of enabling the Communes to collaborate with each others while maintaining autonomy, so those are not simply state-directed objects, which was very difficult in the former French local administration system. Finally, transforming to CA (Communautes d'agglomeration:city community), EPA as an intercommunal corporation is possible to extend its purpose to the domain of regional planning including new town and periphery areas and change its position to a subject which can practice Commune's sustainable development according to stages of city's development and maturity. The most important implication of this study on urban development in Korea is that administrative consultative council or association among local governments and related authorities need to be established and effectively operate because multi-stakeholders could share a goal of urban development and management through that.

This paper analyzes characteristics and changing phenomenon of Chonsei & monthly rental real estate market based on a survey of participants. The frequency analysis, mean analysis, and cross-table analysis was utilized for this study, and a survey for 2,000 rental market participants was accomplished. The survey result of tenants and land-owners regarding the Chonsei market stability indicates the expansion of public housing supply is needed together with lowering of mortgage related restrictions. The major conclusions include that the expansion of public housing and rental supports for low-income families are needed, due to the population structural change and an aging society. In addition, survey result suggests the tenants require the expansion of public housing supply for the residence stability.

In this study, crosshole seismic test, donwhole seismic test, SPT uphole test, and suspension PS logging (SPS logging) were conducted and the shear wave velocities of these tests were compared. The test demonstrated the following result: Downhole tests showed similar results compared to those of crosshole tests, which is known to be relatively accurate. SPS logging showed reliable results in the case of no casing, i.e. in the rock mass, while, in the case of soil ground, its values were lower or higher than those of other tests. SPT-uphole tests showed similar results in the soil ground and upper area of rock mass compared to other methods. However, reliable results could not be obtained from these tests because SPT sampler could not penetrate into the rock mass for the tests.

One-third of total energy and 50% of
emissions arise from construction phase. Because of this global amount of energy consumption and
emission, we must do our best to solve this problem. But our existing ways of meeting this problem has focused on the energy consumption saving of the construction and dwelling stage. On the other hand, we has been treated too lightly for handling the
emissions problem during the maintenance management and the demolition process so far,. In this paper, we quantitatively predicted and evaluated the environmental load in each construction step during all life cycle. And, we developed the environmental load assessment program for each construction step. And we proposed the reliable decision support model for objective and reliable environmental load assessment and reduction. This result must help the development of construction technology and low carbon & green growth.
Applicability of the Hysteretic Steel Dampers to the Shear-wall Dominant Apartment Buildings
Chun, Young-Soo ; Park, Ji-Young ;
LHI Journal of Land, Housing, and Urban Affairs , volume 3, issue 4, 2012, Pages 407~413
DOI : 10.5804/LHIJ.2012.3.4.407
In this study, the possibility of applying the damping devices to shear-wall dominant apartment buildings(SDA) was examined. In order to achieve research objectives, ASCE/SEI 7-10 design procedure for structures with damping systems applied to four representative apartment buildings which are under design or previously designed with the shear-wall dominant system, and the performances of damping devices were investigated. It is shown that in order to secure the seismic performance of SDA by using dampers, the stiffness of the dampers should be very large because of the effects of shear walls with the high elastic stiffness. But since this large stiffness is highly difficult to implement in reality, prudent decisions have to be made in designing the SDA with damping system and friction dampers with the high initial stiffness are more effective than hysteretic steel dampers.

In case of Korean housing complex, there became more mixed arrangement of buildings with different number of layers for a variety of urban skyline, recently. For example, around 33% of the construction sites of 'A' public corporation have gaps of more than 4 layers between high-rise buildings and low-rise ones in the same site, according to the survey. Generally, construction duration of the housing complex is estimated based on the layers of the highest building. Due to this baseline, whole construction duration could be extended so that the project cost could be increased. Therefore, framework duration of higher-rise buildings should be reduced to secure the feasibility of the project. On the other hands, these shortenings could adversely harm the feasibility in some cases because there are a wide range of combinations of the buildings with different number of layers in designing housing complex. Therefore, this study shows the results of analysis on effects of framework time shortening on the cost in housing complex project. Moreover, this could set the baseline of checking possibilities in condensing the construction duration of projects with buildings of different layers by supplying comprehensive database.

The trends of Green growth and environmentally-friendliness came to be the key development indicator for sustaining global environment for the future. Korean government reflected these trends in the main flows of the national development index. Korean construction industry is concentrating investment on fields related to these trends such as technologies for carbon dioxide deduction, materials or products for environmentally-friendly building and alternative energy development, as well. However, efforts to follow these trends during the construction process as a step for production phrase are not being considered enough. In this study, we analysed current status and points to be improved of on-site environment management by surveying major project owners and representatives of the environmental affairs in the leading companies of those fields. Also, we suggested organizational structure and operation model as a solution for enhancing environmentally-friendliness for systematic approach to manage on-site environment in public construction sites. In addition to these solutions, further approaches such as shifting paradigm of project owners and contractors, securing workforce and practical budget for efficient management activities, developing environmental management manuals, setting standards for evaluation of activities are needed for the stable settlement of on-site environmental management.

DOI : 10.5804/LHIJ.2012.3.4.433
An experimental investigation was conducted to study the behavior of RC wide beam-column joints with slab subjected to reversed cyclic loads under constant axial load. Six half scale interior wide beam-column assemblies representing a portion of a frame subjected to simulated seismic loading were tested, including three specimens without slab and three specimens with slab. The primary variables were the ratio of column-to-beam flexural capacity (
; 0.77~2.26), ratio of the column-to-beam width (b/H ; 1.54, 1.67). Test results are shown that (1) the current design code and practice for interior joints(type 2) are apply to the wide beam-high strength concrete column. (2) the presence of a slab have an effect on the performance of the wide beam-high strength concrete column interior joints(type 2). therefore in the design of the wide beam-high strength concrete column interior joints(type 2), the width of slab effective as a T beam flange should be considered. It was show that the case of the ratio of column-to-beam flexural capacity is more than 2.0, the effective width of slab are 2 times of an effective depth of wide beam, however if the ratio of column-to-beam flexural capacity is 1.4~2.0, the effective width of slab are not able to be considered.

Kim, Sang-Yeon ; Park, Jong-Bae ; Park, Yong-Boo ; Kim, Dong-Soo ; Lee, Sei-Hyun ;
LHI Journal of Land, Housing, and Urban Affairs , volume 3, issue 4, 2012, Pages 451~456
DOI : 10.5804/LHIJ.2012.3.4.451
In this study, a numerical analysis to evaluate the reduction of seismic load due to pile group was performed and compared the peak ground acceleration(PGA) measured at free-field and foundation. The special attention was given to the amplification of seismic acceleration on the foundation due to the pile effects. The analysis considering pile effects was carried out for 4, 8 and 12 piles with same condition by PLAXIS 2D Dynamics. Based on the analysis results, it is found that the overall reduction in seismic load due to foundation and reduction rates are similar irrespective of pile numbers. This study gives a possibility for effective design of piled foundation by reducing seismic load about 20~25%.
