    Abstract PDF
    It can be helpful to look over the traditional discussion about the conditions of dwelling environment for examining Korean Healthy & Longevity City prototype. Intellectuals were regard the dwelling environment as the basic and important factor in the Late Joseon Period. Fengshuimainly fulfilled its function as the welling location theory and the environmental management principle. There are lots of useful contents on the Healthy & Longevity dwelling environment in the documents(Sallimgyeongje, Jeungbosallimgyeongje, Taengniji, Imwongyeongjeji) of Confusion Silhak School. The suitable spatial scale fit the environmental capacity and the succession of the nature friendly dwelling tradition are needed to get to achieve the Health & Longevity city project in Korea. This research could be a help to make ideal concept and model of the Korean style Healthy & Longevity city.

    Analysis of Change in the Population Distribution Based on Spatial Relationship Using the Sphere of Influence

    KIM HOYONG | 2012, 73() | pp.47~61 | number of Cited : 7
    Abstract PDF
    Recently, there has been a wide range of research in space by introducing the concept of spatial relationship such as spatial autocorrelation. It is very important to set a spatial-weighted value according to the analysis target since spatial effects differ due to a variable affecting space in the study of applying spatial relationship. It is, however, as a matter of fact that researches with regard to setting methods and usefulness of spatial-weighted values fit for the analytic purpose lack. Accordingly, this study presented an appropriate model for analyzing the population distribution change and spatial-weighted value setting by applying the concept of spatial relationship. The results from the analysis using the population data collected every 5 years for 50 years since 1970 interpreted the population distribution change as well as exploring urban planning backgrounds including a large scale development affecting chronological population change. In order to interpret population change and spatial relationship, Anselin’s local Moran’s I model useful for spatial cluster and outlier analysis and spatial-weighted value methods for the sphere of influence type regarding the spatial distribution characteristics of accumulation unit and applying the reaching distance of influence from each respective unit were well-suited.

    A Study on the Network Residence of Single Career Women in Korea

    Jungmin Choi , 박영미 | 2012, 73() | pp.63~82 | number of Cited : 4
    Abstract PDF
    This study focused a separate residence of single-person household which is recently growing rapidly, analyzed exchanges and mutual aids in respect of network residence, scope of family recognition, realities of housing expenditure burden, etc. and sought policy implications. For this, a survey was performed for 1,000 single office women nationwide from 20’s to 40’s who are living apart from their main families. The results of this study are as followings. First, major elements of choosing residential areas for single career women are accessibility for mass transportation, convenience for workplace and cheap housing expenditures and the most layout of residence housing was a type with more than 2 bedroom space. Second, as for separation cause, workplace(64%) followed by seeking independence life(24%) was most and they communicated with main families with mobile phones(98%) once in 2~3 days(30%) as for major communicating means. Third, it was found that the average monthly income was 2,100 thousand Won and composition of expenditure was housing expense including rental fee and administration charge(17%, 360 thousand Won), food expenses including eating out(19%, 400 thousand Won), transportation & telecommunication expenses(10%, 210 thousand Won), living expenses including shopping(21%, 120 thousand Won), money transfer to main families(6%, 120 thousand Won) and saving amount(27%, 570 thousand Won).

    A Study on the Optimality of SOC Investment : An Endogenous Growth Model Approach

    Ryu Deockhyun | 2012, 73() | pp.83~97 | number of Cited : 8
    Abstract PDF
    This study aims to evaluate the optimality of SOC investment in Korea. To do this, we employ an endogenous growth model to assess the optimality of SOC investments in the central government, local government, public enterprises, and private-public-partnership investment. The theoretical ratio of SOC investment to GDP is 2~4% with 3~5% of GDP growth rate, 0.255 of output elasticity, and 1~2.5% of depreciation rate of SOC stock. The actual 2004-10 SOC investment to GDP ratios of the central government budget were bounded within a proper scope in the context of central government. However, if local government budgets, public and private investments included, the ratio was significantly increased to 4.28% in 2010, that can be seen to the maximum range. Meanwhile, the investment ratio in the 2011-15 National Fiscal Management Plan on the SOC is shown to be appropriate in terms of this evaluation model.

    A Study on Effect of Housing Asset on Financial Portfolio Choice of Households

    임미화 , Eui-Chul Chung | 2012, 73() | pp.99~114 | number of Cited : 13
    Abstract PDF
    The purpose of this study is to analyze the effects of housing asset on financial portfolio choice behavior of households in Korea. Financial and liquid assets are divided into two categories based on the degree of risk: a relatively safe asset such as savings and insurance and a relatively risky asset such as stocks, funds and derivatives. Our focus is on how housing related variables affect households’ risky asset holdings. Housing related variables include housing tenure, amount of mortgage principal relative to house value, and house value relative to total asset. Similar variables are also considered for the other real estate. Empirical results show that the ratio of risk asset to liquid asset is higher as households have more income and net worth and as they have higher risk preference for financial asset investment. It is also found that the ratio of mortgage principal to house value and the ratio of house value to total asset are important variables to their risky asset holdings. Thus, it can be concluded that households’ financial portfolio choice is strongly influenced by their real estate decisions.

    The NOI Growth Rate and the Risk Premium Adjustment Process of the Office Buildings in Seoul

    Seonghun Min , Koh Sung Soo | 2012, 73() | pp.115~129 | number of Cited : 9
    Abstract PDF
    Determining the risk premium of office and understanding its adjustment process is important for office investors, because risk premium is a fundamental element of discount rate and its change is directly reflected in value. This study conducts 1) the estimation of NOI growth rate using actual data on the rent and vacancy rate 2) the calculation of risk premium based on the Gordon Growth Model 3) the analysis on the adjustment process of risk premium through the Error Correction Model on the office in Seoul. The empirical result suggests that 1) there is very rapid risk adjustment mechanism in Seoul office market with the error correction term of significant -0.9093 2) office absorption(-), CPI(+) and vacancy rate(-) in long-term equilibrium and office absorption(-), vacancy rate(-) and interest rate(-) in short-term adjustment were significant. The reason why vacancy rate is (-), which was expected to be (+), seems that the increase of vacancy rate under the level of natural vacancy rate doesn’t affect significantly on risk premium and investors apply not so high capitalization rate as the increase of vacancy rate immediately in that situation. This study is the first case of analyzing risk premium of office in Seoul using actual NOI data.

    Developing Trip Generation Models Using Spatial Regression Analysis : A Case for Seoul, Korea

    Jin Changjong , Hyang sook Lee , Choo Sangho | 2012, 73() | pp.131~143 | number of Cited : 12
    Abstract PDF
    The paper develops trip generation models using the 2006 Seoul Household Travel Survey data for trip production and attraction models by the total and purpose(commute, school, shopping, business, others). The existing models frequently use linear regression models assuming independence among the error terms. However, traffic analysis zones(TAZs) are not simply distributed at random while having autocorrelation each other. To control such autocorrelation, spatial regression models need to be considered rather than linear regression models. Therefore, the paper examines the autocorrelation for trip production and attraction, and verify if the spatial regression models are suitable. Then, SEM(Spatial Error Model) or SLM(Spatial Lagged Model) is estimated according to the spatial regression decision process. The results indicate that spatial regression model is more reliable for most trip generation models except the school attraction model and other production/attraction models. The paper provides the improved trip generation models by applying the spatial interactions among TAZs and land use data.

    Feasibility Study System for “National Rental Housing” Development Project

    Ryu Sungho , Lee Yongbum , Seon-Jong Yoo | 2012, 73() | pp.145~162 | number of Cited : 2
    Abstract PDF
    It is necessary to make an accurate judgement of the loss size of the project through the close economic analysis to achieve the smooth supply of rental housing for the stability of common people’s dwelling. It is thought that it is necessary to consider the loss compensation scheme through this. For this purpose, this study attempted to investigate the improvement scheme of the economic analysis system with the construction and operation of the national rental housing No. 1. The application of crosssubsidization was made clear by dividing it into the land sector and the housing sector, reflecting the loss arising from the supply of rental housing land in the land sector and reflecting the legally administered price for rental housing land in the housing sector. And it was made possible to make an economic analysis of each sector by dividing it into the construction project and the rental project. Second, the economic analysis system was reestablished by introducing the annual average rising rate of land price in calculating the sales price of rental housing. Finally, an attempt was made to analyze the economic analysis system by dividing it into the capital cost of the construction project and of the rental project. Analysis showed that great loss occurred in the rental project sector other than the construction project.

    An Analysis on the Classification of Regional Development Using “Just Growth” Characteristics: Focusing on Seoul Metropolitan Area

    Kwang-Sik Yang | 2012, 73() | pp.163~181 | number of Cited : 1
    Abstract PDF
    It has traditionally been presumed that economic growth reduces poverty mainly through tricklingdown effect, but it also has a deleterious effect on the level of inequality in a society. Because new paradigm is necessary to change regional policy which social equity, as a ideology and value for regional development, can be improved in spatial planning. From this perspective, this research was to analyze a regional development level and a correlation between economic growth and social equity using “Just Growth” Concept. Four policy directions are suggested. First, it is necessary to set up new goals and strategies for regional policy with regional development level. Second, the local governments are oriented mostly regional policy for enhancing social equity. This indicates that social cohesion and regional stewardship to improve the social equity are strongly required. Third, this study found that new political guideline can be introduced using regional development level. Firth, policy directions should be suggested to enhance the cooperative regional development.

    A Proposal for Effective Management of State and Public Land through Land Consolidation: Case of Public Land Consolidation in Cheongju

    조영태 | 2012, 73() | pp.183~202 | number of Cited : 2
    Abstract PDF
    Of state and public land managed by the national and local governments, the land which is used for public use may be composed of a plural number of land units, even if it is occupied by one single facility. As management of public facilities standing on a plural number of land units has its efficiency compromised, local municipalities consolidate sites used for a set of public facilities as a solution to the problem. This thesis aims to push for effective and aggressive consolidation of public lands by making a proposal regarding the obstacles arising in the process of consolidation. The study has examined different cases involving a survey related to scale change, registration conversion etc, or conflicts related to registration, or mismatch between official documents related to real estates, or unreasonable administrative zoning, or passive management by management authorities to suggest solutions.

    Knowledge Externalities in Regional Labor Markets : Evidence from Occupation-related Knowledge Requirements

    Sungchul Cho , Lim,Up | 2012, 73() | pp.245~260 | number of Cited : 3
    Abstract PDF
    This paper examines the role of occupation-specific knowledge requirements in wage inequality across regional labor markets in Korea. By employing a hierarchical linear model, this study can help us to understand the sources of wage inequality and to estimate its magnitude more accurately. This study also introduces an alternative way of measuring local knowledge. We use the data from the Korea Network for Occupations and Workers. The major finding is that high knowledge in the areas of business and management, engineering and science has a positive effect on individual wages, while high knowledge in production and design is not rewarded or even penalized in the labor markets. According to the results, knowledge externalities are found mainly in the area of business and management.

    Case Study of Time Headway Distribution on Suburban Arterial

    parkchangsoo , 장진환 | 2012, 73() | pp.261~270 | number of Cited : 1
    Abstract PDF
    Time headway is fundamental importance in traffic engineering. For any of the traffic simulations to address traffic problems to be effective, accurate vehicle generation is essential. Previous research into this subject has focused on the stochastic modeling for uninterrupted facilities. Yet little researches for an interrupted facility have been performed. This paper proposed the theoretical headway models for a suburban arterial in Korea. Using the laser sensor-based traffic detector, a large amount of accurate headway data was obtained. To analyze by traffic flow states, the headway data were divided into five flow states. Subsequent runs test rejected the randomness for the 5-9 v/m flow. Hence, theoretical modeling for the remaining flow (10-14 v/m, 15-19 v/m, 20-24 v/m, and 25-29 v/m) is performed. The goodness of fit tests by Kolmogorov Smirnov (KS) statistic revealed that the Johnson SB model for 10-14 v/m flow, the Johnson SU model for the other three flows fitted best. The Log-Logistic model was second-best for 20-24 and 25-29 v/m flow. The Log-normal model was also accepted for 25-29 v/m flow. Some analyses not only on the statistics of the headway, but the fitted model exhibited somewhat different characteristics compared to those of the headway from uninterrupted facilities. This paper can provide better understanding of the headway from interrupted facilities and starting point for developing a well-descriptive simulation model for signalized arterials.

    An Analysis on Economic Effects of Overseas Construction

    Kim, Myeong-soo | 2012, 73() | pp.271~281 | number of Cited : 10
    Abstract PDF
    This study tries to analyze the economic effects of overseas construction on national economy, using Input-Output model. National economic effects are investigated in forms of inducing production effects, inducing value-added effects, and inducing employment effects based on the Input-Output model. It is derived that 0.88 trillion won, in the year of 2011, flows into national economy from overseas construction activities. Domestic inflow of the sales of overseas construction as factor for production has the same input-output structure as the domestic construction industry. It is assumed that domestic inflow of the sales of overseas construction as factor for production is an export (the change of final demand), then I-O analysis is executed. The 0.88 trillion won, domestic inflow of sales of overseas construction, causes 1.24 trillion won production-increasing effects, 0.67 trillion won value-added effects, and 100,000 creating employment effects. It is needed to collect more specific data on the structure of overseas construction for further study in the future.

    A Case Study on the CRPs and Political Implications

    Kim Joojin , 송영현 , 김옥연 | 2012, 73() | pp.283~302 | number of Cited : 5
    Abstract PDF
    This study considers 4 conjoint renewal projects(CRPs) including Emun-3 rearrangement zone(RZ), Haebangchon RZ, Wonmi-6B RZ and Kwangmyung-11R RZ and suggests main political implications for activation of Conjoint Renewal Program(CRP). On the base of the case studies, we find that the detailed purposes or backgrounds of CRPs are similar but the conflicts phase between local government and residents depends on some differences in the aspects of the decision making process, the socioeconomic characters of communities, and residents’ attitudes to the renewal projects. The main political implications are as follows ; First, CRPs should be applied for the public good which is directly related to the residents of CRP RZs for flexibly carrying out the policy. Second, it is important to make consensus and converge residents opinion on the RZ by the law. Third, it is required to comprehensively consider not only the physical conditions but also the socio-economic qualities of RZ communities to designate RZs. And the last, the CRP incentives should be increased to draw profitable RZs for facilitating CRPs.
