    Effectiveness on Storm Water Management of Green City Planning Elements: Focusing on Multipurpose Rainwater Utilization Facilities

    윤재봉 | KWON TAE JUNG | 2013, 77() | pp.3~16 | number of Cited : 5
    Abstract PDF
    This study attempts (1) to find effective urban design elements in consideration of both heavy rainfall hazard mitigation and green city planning and (2) to evaluate their effectiveness in the field, a natural disaster-prone urban district in Busan, Korea. The analytical matrix considering previous green city planning research and ICPP’s three factors of disaster risk suggests three main urban design elements that can be used against heavy-rainfall natural disaster, which elements include green roof, permeable urban surface, and rain water utilization facility. Rain water utilization facility is, however, introduced alone to the field analysis given that its effectiveness has not been fully tested in the previous studies. The field analysis using EPA-SWMM reveals the possible role of rain water utilization facilities in reducing the amount of the peak flow reduction as well as in expanding the runoff flow time. The analysis also suggests that a better result is expected when rain water utilization facilities with small-to-medium capacity are introduced in a dispersed way. The analytical results help guiding municipal governments’ hazard mitigation efforts in consideration of green city planning and also promoting future studies to make connections between green city and hazard resilient city planning efforts.

    Taewon Park | CHun, Hyeonsook | Song Hyangsook | 2013, 77() | pp.17~34 | number of Cited : 4
    Abstract PDF
    This study is conducted to setting up planning components of women-friendly housing complex by carrying out an exploratory survey on what women need in an apartment housing complex. Because, previous studies are macro-oriented discourse about the direction of the urban planning. In order to enhance feasibility of planning components, not only qualitative research but also quantitative research of factor analysis and AHP (Analytic Hierarchy Process) are used together. As a result, 32 sub-factors and 6 major factors are selected. According to importance, the 6 major factors are safety, childcare affinity, life convenience, pedestrian amenity, self feasibility and aesthetic landscape. Through that process, the planning components of women-friendly hosing complex was set up. This Criterion is expected to be used in planning housing-complex development in near future. In addition, this study need to go along and consider the various types of co-housing and expanded samples.

    The Regional Effects of Interest Rate Change: Multiregional CGE Model Approach

    Jeong, Kiho | Kim, Jae-hyun | 2013, 77() | pp.35~48 | number of Cited : 1
    Abstract PDF
    This study analyzes the regional economic effects of changes in interest rates. Since the regional differences of economic structure are relatively large in Korea, the effects may be not the same over regions. A multi-regional CGE model is used for the analysis. The multi-region SAM is constructed using the 2005 regional input-output table and the regional data. In the scenario analysis of 10% increase of the call rate, it is found that production goes down in most regions, except for Gyunggi, Daegu, Gyeongnam which are unaffected and for Incheon in which production increases. The relative prices decline in major industry sectors in most regions, while the relative price of real estate increases in all regions, primary metal products’ either increases or is unaffected depending on regions and the relative prices of the major industry sectors except for the construction sector’s increase in Chonnam. The reason of the regionally different ripple effects on production and relative price of the rise in interest rates seems due to different capital-intensity among regions. It is shown that the larger the capital intensity is in a industry sector or and a region, the larger decrease of production the sector or the region has.

    A Study on Driver’s Gaze Area in Variable Road Characteristics Using Eye Tracking System

    Park Jinho | Hyung Chul Kim | 2013, 77() | pp.83~101 | number of Cited : 2
    Abstract PDF
    Eye tracking system means tracking and detecting the movement of driver’s eyes using a series of device. This study analyzes driver’s gazing area in variety of road characteristics using Eye tracking system. The contents of this report include the history of development in terms of the techniques of eye detection and the application of Eye tracking device. For collecting driver’s eye gazing data, we used a head mounted device to 14 people in various road conditions. In the conclusion section of this study, gazing characteristics of drivers’ eyes change according to the road characteristics, speed of the vehicle, number of lanes, and environment of running road. Moreover, we found drivers’ eyes are more shifted to the other various spots when the vehicle is stopped on the crossroads compared to on the normal road and express road. Furthermore, the drivers’ eyes dispersed more on the urbanized roads than on the rural roads, and more on the two-way with 4 lanes than on the two-way with 6 lanes. It can be adopted when we design and plan the road and also set the location for street furnitures and transportation facilities.

    Social Contribution and Optimal Level of Road Capital in South Korea

    Kook Woo-Kag | 2013, 77() | pp.103~117 | number of Cited : 2
    Abstract PDF
    In order to better inform decision-makers, more work should be done. More work should be done to analyze how Road investments and the provinces impact national economic growth and competitiveness. More work should also be conducted to understand the costs and benefits of Road investments and their industry specific impacts across national. Using a set of “aggregated” estimates, we calculated the “optimum” level of road capital and compared it with its actual level over the period 1970~2007. This results emerges is that the ratio of the optimum to actual road capital, measured by road, was high at beginning of the period 1970s and declined 2000s. There appears to be evidence of under-investment in road capital. That is continuous and premeditated investment for road which lead to saving time and finance. Contribution of the road capital of total factor productivity growth was positive (+) in the total industrial. The degree of contribution to total factor productivity growth in the total industry was disembodied technical change, an exogenous demand effect, road capital effect. In addition, Road capital contribution in about 0.13 which compared with reported estimates in the literature is relatively small.

    Housing Tenure Transition Decisions of Older Homeowners in Korea

    Eui-Chul Chung | 2013, 77() | pp.119~136 | number of Cited : 21
    Abstract PDF
    This study examines housing tenure transition decisions of homeowners. The focus is on transition from homeownership to renting. Based on a panel of households over 55 years of age obtained from 2004~2008 KLIPS data, discrete time hazard models were estimated to figure out the key determinants of tenure transition. Contrary to the traditional life cycle hypothesis, older owner households are not likely to move until the age of 75. Estimation results of hazard models show that the relative weights of housing asset to total asset and of financial asset to total asset are important variables in explaining older households’ tenure transition decisions. While the ratio of housing asset to total asset is positively related to their tenure status change from owning to renting, the ratio of financial asset to total asset negatively affects the change. This implies that housing wealth are not consumed until nonhousing wealth has been consumed. Another important finding is that demographic factors influence tenure transition decisions to a greater extent. Health status of household’s head and spouse, change in the head’s marital status, death or disappearance of the head are important determinants of tenure transition process. Employment status of the head is also found to be influential.

    A Study on the Performance of Local Public Investment Policy and Its Implication on Balanced Local Development Policy: The Case of Gyeongsangnam-do

    Choe, Byeong-Ho | Keunjae Lee | Shin Seyong | 2013, 77() | pp.137~154 | number of Cited : 2
    Abstract PDF
    The objective of this study is to figure out some policy implication on the ongoing Balanced Local Development Policy of Gyeongsangnam-do by evaluating the outcome of the public investment policy for under-developed localities initiated by the central government. Main findings are as follows: First, the impact of public investment policy on local economic growth has appeared to be greater in the cities than the under-developed counties. Second, it is shown that public capital has been over-provided in counties so that there is a considerable inefficiency in the spatial allocation of public capital. Third, the public capital invested in the counties has appeared to be weak inducement effect to private capital. Fourth, it is shown that the economic growth of the counties has not been guaranteed by the expansion of public capital. These results bring up some important questions to the effectiveness of spatial public capital allocation policy initiated by the cental government. More importantly, the findings suggest that the same type of policy led by Gyeongsangnam-do regional government is required to be reconsidered or redirected.

    Housepoor Problem: Diagnosis and Remedies

    KIM, JUN HYUNG | 2013, 77() | pp.155~174 | number of Cited : 5
    Abstract PDF
    This study defined the housepoor as households who have used mortgage financing to purchase housing for the purpose of residing but are facing unaffordable debt service. Based on this definition, this study analyzed the micro data of Survey of Household Finances and Living Conditions by Statistics Korea, and found 70 thousand households fit the definition of housepoor, 0.4% of total households. Adding those households at risk of becoming housepoor, it increases to 328 thousand households (1.8% of total households). Policy implications are as follows: first, we need more detailed definition of housepoor in terms of concept and operation. Second, the target group of the policies should be specified, particularly with regards to the occupancy status of the homeowner. Third, the voluntary rescheduling of loan payment between lenders and borrowers should be regarded as the first and the best solution. Fourth, the DTI (Debt-to-income) regulation should be restored in the policy package (its removal being a major factor resulting in the housepoor). Fifth, government intervention would be inevitable due to the need to protect homeowners who have to move out of a house and chonsei-tenants who wish to move in. Finally, before announcing more detailed policies for the housepoor, the research on the characteristics and the necessity of government intervention for them should be performed.

    A Study on the Characteristics of Reverse Mortgage Contract and Its Influence Over Monthly Payment

    Seon-Jong Yoo | Lee Seokhee | 2013, 77() | pp.175~188 | number of Cited : 7
    Abstract PDF
    The main variables that affect when calculating Reverse mortgage’s monthly payment based on actuarial model are big changes in the economic environment. Inflation on Housing price, expectation on interest rates and demographic factors that influence on life expectancy. A paradigm shift in retiring financial services markets is to be expected. A new standard of reverse mortgage’s monthly payment will be reflect by stable housing prices, rise in average life expectancy. The purpose of this study recognize the changing demographic characteristics of reverse mortgage subscriber and examines any impact on the way they are calculated to determine the monthly payments. As a result, the independent variables that affect monthly payments are house prices, building area, address, total guarantee fees, the sum of loan, payment methods, payment type, age, and household make-up. That shows a total of nine variables significant at the significance level of less than 1%. Among them, payment type variable shows that affects the most on contract characteristic parameter of pensioners which is research focus of this paper sum of mortgage amount comes as second influencing variable in estimation of monthly payment of reverse mortgage. These results, when viewed in light of the analysis from the perspective of reverse mortgage provider, presents implications for the policy-making authority.

    Estimating Urban Railway Demand Based on Catchment Area

    Lee Euna | Shon Eui-Young | Kim Seoljoo and 1other persons | 2013, 77() | pp.189~203 | number of Cited : 5
    Abstract PDF
    Currently the urban railway is constructed in some metropolis to solve the traffic congestion, but some errors have occurred in estimating its demand. In most cases, the demand is calculated from the basis of traffic analysis zone (TAZ) as a minimum administrative area, i.e. Haengjeong-dong. Here all trips in Haegjeong-dong are assumed to be generated in one location. However more than two urban railway stations might be located in one Hangjeong-dong. So the actual demand of urban railway is most affected by the catchment area rather than Haengjeong-dong. Therefore, the segmentation of TAZ based on the catchment area is required to estimate its demand more accurately. In this study, the estimation model based on the catchment area has been developed and its demand forecasting has been made using the newly developed catchment area based model. As a result, it shows the urban railway demand estimation by the catchment area is more accurate than that by Haengjeong-dong. That is, this study shows that it is possible to estimate urban railway demand more accurately by segmenting TAZ based on the catchment area.

    Asymmetric Effects of Oil Prices on Highway Travel Demand in Korea

    Lee Jaimin | SangYong Han | 2013, 77() | pp.205~225 | number of Cited : 0
    Abstract PDF
    We investigate the effects of oil price changes on highway travel demand using Korean monthly data and time series analysis. In detail, we examine if oil price elasticities for the highway travel demand when oil prices are high are less than those when they are low. In order to find this asymmetry, we use the monthly numbers of vehicles and vehicle-kilometers in the first type car from January 2000 to December 2008 provided by the Korea Expressway Corporation. We use monthly oil prices as a key explanatory variable and also control other explanatory variables such as real gross domestic product, length of highways adjusted by lane, and so on. We run unit root test for non-stationarity and cointegration test among them for long-run relationship. We estimate them using autoregressive distributed lag model and error correction model. Based upon the analysis, we can say that there are asymmetric effects of oil price changes when oil prices are low or high. The agents to use private cars in the highway when oil prices are low from January 2000 to June 2004 responded more sensitively than when oil prices are high from July 2004 to December 2008.

    Analysis on Characteristics of Residential Property Management Companies in Japan and Its Implications

    Sang-Young Lee | 2013, 77() | pp.227~240 | number of Cited : 8
    Abstract PDF
    The government supports to develop the residential property management (RPM) industry in order to stabilize rent markets in Korea. However, for the subject and the institutional support system of this industry are ambiguous, the analysis on paths of industrial development in Japan is needed in order to understand this industry. Especially, in the use of individual companies data, characteristics of RPM companies in Japan have been studied. This analysis is concluded that the synergy of RPM in Japan is made of 4 industries, i.e., real estate brokerage, FM, construction, architecture design. Among these industries, the construction companies have led the sub-lease business to the big size. For these companies have had a high credit of this area and synergy effects with RPM. Many players in the Korean real estate markets are interested in developing sub-lease business, the same as master lease business in Korea. If the sub-lease business is growing to the level of that in Japan, the tax deduction on owners of rent house and the rent surety insurance of tenants should be institutionalized.

    Cultural Cluster Strategy as a Tool for Urban Revitalization: Case of Daein Art Market in Gwangju Metropolitan City, Korea

    SeHoon Park | Kim Eun Ran | 2013, 77() | pp.241~260 | number of Cited : 14
    Abstract PDF
    With the rise of cultural economics in the post-industrial cities, the urban cultural strategies have been widely accepted as a effective tool for urban revitalization. However, the previous literatures have paid little attention to what factors behind cultural strategies can produce desirable consequences, and how we need to implement the strategies to make sure to generate positive impacts on neighborhoods. By adopting the research framework of the industrial cluster studies which has been developed in the economic geography circle, the paper tried to develop the conceptual model of the cultural cluster strategies and applied the idea into Daein art market in Gwangju Metropolitan city. Daein art market, a traditional market at the city center troubled with declining number of customers, is now trying to revitalize itself by harnessing the activities of local artists clustered at the market. Focused on the three factors of the cultural cluster strategies which are the sense of community, the work network and the local connections, the paper attempts to shed light on the potentials and the limitations of cultural cluster strategies in Korea.

    A Study on the Improvement of Evaluation System of the Contractor’s Construction Capacity through the Questionary Analysis and the In-Depth Interview with Experts Group: Focused on the General Construction Company

    Kim, Seong Yeun | 2013, 77() | pp.261~276 | number of Cited : 3
    Abstract PDF
    The purpose of this study is to analyze the problems of the Evaluation System of the Contractor’s Construction Capacity (ESCCC) and suggest some efficient improvements of it. In order to achieve the goal, this study reviews preceding research and categorizes the problems of ESCCC as the lack of relevance in providing information, the concern for possible information distortion and the limit in protecting and promoting Small and Medium Construction Company (SMCC). Depths interviews and surveys are carried out to examine the understanding of expert group on these problems. According to the results, they answered the ESCCC does not provide sufficient information of construction firms relevantly. They also showed positive stance on the appropriateness of the criteria in assessing the Evaluation Amount of the Contractor’s Construction Capacity (EACCC) and the effect of the ESCCC on the protection and promotion of the SMCC. However, the expert group was divided apparently in terms of providing information by the ESCCC. In order to improve the on-going ESCCC, this study proposes that specifications consisting the EACCC be changed into public announcement on a rolling basis and qualification procedures in case of revising detailed creiteria be established. Furthermore it is suggested that the policy object be selected clearly through the ESCCC to protect and promote the SMCC.

    A Comparative Study of the Production Structures and Production Technologies in the Seoul Metropolitan Region and the South East Region in Korea

    Kim,Gyeong-Pil | Lee, Jin-sang | 2013, 77() | pp.277~291 | number of Cited : 0
    Abstract PDF
    This paper investigates overall production structure and production technologies of regional industries in the Seoul Metropolitan Region and the South East Region in Korea by the method of triangulation. The Seoul Metropolitan Region and the South East Region have different industries as more of IT industries and high-technology industries are located in the Seoul Metropolitan Region, whereas heavy and chemical industries are in the South East Region. Even though both regions have different industrial structure, the basic characteristics of production structure of two regions are very similar. To find the degree of similarities of production structure and production technologies, the Spearman rank correlation coefficient (r) was calculated. The value of r was 0.64258 and strongly supports the similarities of production structures in both regions. We compared the production technologies of detailed industries in both regions by the absolute column measure which was used in the previous studies. P-values reflect the differences of production technologies and it is less than 1 at the base line in most industries except the chemical industry. These findings show us that similar production technologies are being used in production process in two regions. This study concludes that there are considerable similarities in regional economies. With the methodologies used in this research could be more meaningful if we apply detailed regional input-output tables, and the results could support regional industrial policies.
