The purpose of this study is to examine the differences among the income level groups of young single-person households and newlywed households in factors affecting the choice of residential location in the Seoul metropolitan region. To summarize the results of the analysis, first, there were differences in the factors affecting the choice of residential location by income level in both single-person young households and newlyweds. Second, among young households, the low-income group showed a behavior of choosing a residential location based on bounded rationality considering the economic condition of the household. Third, even though the income level is similar, the difference in the factors for choosing a residential location between single-person young households and newlywed households was confirmed, which is results of the life-cycle changes. These results imply that it is necessary to prepare appropriate housing policies that can supplement the economic conditions of young households living in the Seoul metropolitan region, and to review customized housing policies that reflect changes in life-cycle stages as well as age or income level.

This paper is aimed to study on residential choice after retirement. For this reason, this study is analyzed in three aspects ; the factors of residential choice, preferred house types and scales, the characterization of residential mobility. This study reached several conclusions. Firstly, Korea baby boomers are likely to select their residence with different factors after retirement, and they are likely to choose their residence in the view of comfort and convenience. Secondly, apartment resident ratio is shown to be reduced after retirement, and the preference for the country houses and town houses is shown to be increased. Thirdly, the baby boomers don't reduce their residential scale in batches, while they are to show a different appearance depending on the retention scale of housing. Fourthly, The 62.4% of Korean baby boomers is to plan move their residences after retirement, 52.3% of movers, more than half of them, is to go to the different residential area. Fifth, it is analyzed that different variables are to influence on the local and regional of residential mobility of the baby boomers in Korea.

In this study, the author suggests utilizing unsold and unused land as temporary commercial parking lots as a way to raise funds for active public transport use. In addition, reasonable parking fee scheme is suggested by estimating marginal parking fee and marginal parking distance for the commercial parking lots based on the CVM. The author conducts a survey to investigate citizens' opinion on utilizing unsold and unused land in the urban development project area as temporary commercial transport facilities such as parking lots. Based on survey outcome, travel behavior and requirements are analyzed and marginal parking fee and marginal parking distance are estimated through the Contingent Valuation Method (CVM). The results are as follows: in the single-bounded dichotomous choice model, people are willing to pay 216 KRW for 165m in average for 10 minutes and their willingness to pay goes down against reaching distance to the parking lots from 365 KRW for 50m, 295 KRW for 100m, 173 KRW for 200m, and 51 KRW for 300m; in the double-bounded dichotomous choice model, people are willing to pay 285 KRW for 165m in average for 10 minutes and their willingness to pay goes down as well against reaching distance to the parking lots from 310 KRW for 50m, 297 KRW for 100m, 272 KRW for 200m and 248 KRW for 300m. It is clearly appeared that people's willingness to pay goes higher as distance to reach the parking lots goes shorter.

This paper reports novel empirical results of a choice experiment that elicited the economic values that residents in the Seoul metropolitan area place on the amenity services realized from the landscape views and accessibilities to urban green spaces (i.e., mountains, rivers and urban parks). The 1,000 respondents in the sample were divided into two residential of housing types (apartments vs. houses) and occupancy types (owners vs. tenants). Residents living in apartments are willing to pay an average of 28% (5.0 million KRW per year) above the current housing prices per household for a mountain view, compared to an apartment view from their living room. Their willingness to pay values are about 22% (4.0 million KRW per year) and 10% (1.8 million KRW per year) respectively for a river view and a urban park view. Economic benefits of having access (i.e., a 10 minutes working distance) to mountains, rivers and urban parks are estimated to be an average of 16% (2.9 million KRW per year), 20% (3.6 million KRW per year) and 18% (3.2 million KRW per year), respectively, above the current housing prices per household. On the other hand, access benefits for those residing in houses are 18% (4.7 million KRW per year), 16% (4.1 million KRW per year) and 22% (5.6 million KRW per year) per household, respectively. They are also willing to pay an average of 35% (8.9 million KRW per year) above the current housing prices for keeping or having a garden or vegetation bed. Furthermore, a strong "greenspace premium" is centered around the three Gangnam districts for house-dwellers, whereas it is areas of "new real estate boom" for apartment dwellers.

It has been used so many kinds of architectural materials and interior products in current building construction, and use of composite architectural materials is increasing with the development of chemical technology. As the green architecture has become the center of public interest, much effort is conducted in advanced countries on the LCA point of view, such as restriction of architectural materials that emitting pollution substances, developing of Non-Toxic architectural materials, and recycling of used materials, etc. with the cooperation of related organizations, material manufacture companies, and construction companies. Because the kinds of materials to be used in building constructions are so various, there might be some possibility of personal and subjective choice at the time of materials selection resulting the missing the requirements of building components and the choice of harmful materials to human. One way to resolve the material problem is to present the green architectural materials which coincide with the quality performance at service and not harmful to man and nature. At this point of view, this study aims to develop the material classification model by investigating the major labelling system about green architectural materials in both domestic and abroad and to implement an efficient material selection system by making a powerful database of environmental standard and quality basis of building requirements.

The number of single households in Korea has been sharply increasing due to dissolution of the family community and changes in housing culture. Therefore, there is a need to develop a plan for diagnosis of changes in the housing market in response to a rapid increase of single household to suggest a proper direction of housing policy. This study was conducted to clarify the factors influencing housing occupancy type targeting a single adult household. To accomplish this, a cross-sectional analysis was conducted using the multi-nominal logit model and the Korea Welfare Panel's 9th survey materials. Occupants of ingle households in their 20s and 30s were found to be much poorer than those in their 40s, or older. Additionally, single household in their 20s and 30s, the characteristic of a household having an influence on the choice of housing occupancy type showed a result in a different direction even from the same household characteristic of those in their 40s, or older. Finally, the characteristics of occupants of single households in their 20s and 30s showed room for improvement through public support. Overall, the results of this study implied the need to inquire into the government's periodic support in more diverse ways.

This study applied the value of floor-area-ratio standard calculation method to case areas and analyzed them to overcome the limits of previous studies in calculation methods for area standards and land price (value) standard development rights. The results are presented as follows: First, criteria to select sending areas and receiving areas are needed. Second, calculation methods based on the value of floor-area-ratio standard can be widely used as standardized criteria in various areas. Third, for the connection of sending areas with receiving areas, the connections of 1:1, n:1, 1:n, and n:n are available and the location of possible dealing areas should be considered. Also, the choice of connecting unions that meet the purpose of TDR presented by local governments is available. Fourth, for Gwangju, as receiving areas downtown provide higher profits than previous renewal projects, the application of TDR is available. Application methods to overcome problems are presented as follows: First, criteria to select sending and receiving areas should be prepared and implemented in an order of priority. Second, in calculating development rights, methods based on the value of floor-area-ratio standard should be used. Third, the standards and principles of sending and receiving areas should be designated and possible dealing areas should not be limited.

Double pipe system in which PB pipe is inserted in CD pipe buried in the concrete slab is widely used for cold and hot water supplies in apartment housings. The system, however becomes complicated and the overlaying pipes in the concrete slab weaken the compressive strength of the slab. Also, insufficient insulation increases energy loss. In this work, the problems of the double pipe system are studied and plans A, B, and C are suggested for improvement. In terms of compressive strength of the concrete slab, plan A(total pipe length 73 m) was the weakest and plan B(2 m) was the strongest. Energy loss of plan A was the largest with 558.9 W and plan B was the lowest with 220.7 W. However, considering the combined effect of strength and heat loss, plan C becomes the best choice, which retains the advantage of the double pipe system.

The present study investigates the effects of lopsided regional policy and social prejudice on homeownership disparities by household's place of birth of household head in Seoul. The present study utilizes individual household-level census data (2% sample) to evaluate households' residential well-being denoted by homeownership status during the period of 1980-2000. Decomposition techniques based on tenure choice models were used to provide evidences of the home-ownership disparities caused by regional policy and prejudice. We found that households from Gangwon and Honam provinces represent a disproportionately small percentage of homeownership compared with those originated from other provinces. In the statistical analysis, the present study found that having controlled for the factors traditionally thought to influence households' choice of housing tenure, as well as other housing market characteristics in Seoul, place of birth has played a primary role in determining whether or not households become a homeowner. Most strikingly, while most of the disparity in homeownership ratios between households from Youngnam and households from Gangwon in the housing market is due to the endowment differences in human capitals they bring to the market, those between households from Youngnam and households from Honam is largely due to residual differences explained mainly by social discrimination and prejudice against people from Honam. The present study summarized that place of birth has played a primary role in determining whether or not households become a homeowner in Korea. The present study concluded with some policy issues relevant to this study and suggested some future studies.
