In this study, we try to formulate a FTA negotiation strategy for the Korea-GCC FTA, to open up the GCC construction market to Korean construction companies. We look at what Korean negotiators should include in the Korea-GCC FTA provisions, based on the analyzed problems and the results of the Singapore-GCC FTA and the EFTA-GCC FTA negotiations. We conclude that firstiy provisions to guarantee transparency of the procurement process must be included, and the rights of Korean companies to question and request reviews of the procurement process must be guaranteed. Provisions which prohibit any requirements in the bidding requirements not directly related to fulfilling the conditions of the construction projects should be included in order to eliminate or reduce the requirements for foreign construction firms to hire local sponsors or agents. Offset requirements should also be restricted through the FTA. If such provisions are not possible, the negotiators should insist on an ombudsman system to mediate problems between Korean firms and local agents or sponsors. Also, GCC allows price preferences of 5~10% for suppliers from GCC countries. Korean negotiators should follow the lead of the Singapore-GCC FTA, and negotiate a matching price preference for Korean firms.

This paper has analyzed the causes of Cheonse price hike issue in term of home owners' yield maximization. The results are as the followings. First, I exhibit a critique to the previous studies that monthly rent rate and expected price growth rate are the same. There are thresholds that vary by the home owners' preference of the lease contracts type. It is true only if the expected price growth rate is equal to the sum of monthly rents and loan interests. Second, rental income and sales prices, Cheonse prices, monthly rent rates were analyzed as a function of the empirical relationship. Because of tenants' budget constraints, the more expensive sales price, the percentage of the Cheonse price on the sales price is falls. Finally, based on historical data, I determine the probability distribution of sales prices, Cheonse prices, deposits, rent rates, expected price growth. And assuming a given interest rate factors, how potential homeowners, who seek to maximize expected investment yield, would prefer Cheonse contract estimated through Monte Carlo simulations. The percentage of Cheonse contracts appeared to be shrinking depending on the expected price growth rate decrease. Finally, empirical relationship between MR and security deposit is negative and statistically significant.

Recently, ‘the amended Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents’ was proposed to introduce the Management and Disposal Method(MDM) for the purpose of expanding the application and residents' options of the residential environment improvement projects(REIPs). This study aims to analyze the applicability of the MDM to the project districts empirically, because the development conditions of the districts are different case by case, and to propose the direction toward institutional improvement of major problems which is expected to occur in applying MDM as a countermeasure. The results are as follows; First, the application of MDM can be different depending on the various local conditions including residents' preference on the project methods, residents' affordability distribution, and a feasibility of development profit. In other words, the MDM system needs to be applied differently considering the district conditions. Second, it is required to consolidate planning contents of REIPs for publicness and to prepare the allocation standard of development profit considering investment ratio.

The purpose of this study is to analyze the spatial distribution of the welfare facilities for the aged in Incheon. This study analyzed accessibility of the welfare facilities for the aged in Incheon. Based on GIS network analysis, this study identifies the service areas of the welfare facilities for the aged. Prior to network analysis, the welfare facilities for the aged are classified into three groups considering of walking range of the aged. After the classification, this study conducts network analysis to determine service area of the welfare facilities for the aged. The distribution of the welfare facilities for the aged in Incheon implies that most facilities have unbalanced distribution among inner cities. And there is no location standard about the welfare facilities, while the facilities are distributed based on the character of the operating welfare facilities. The areas with inadequate supply of the welfare facilities are drawn by the density of users. These blind spots should be considered above all in supplying the welfare facilities for the aged.

This study aims to develop an assessment methodology of CNS(Car Navigation System). First, this study defines the concept of benefit of travel time saving. Travel time saving benefit is defined as travel time saving times value of time of traveler who uses CNS. Subsequently, this study develops a methodology to measure travel time saving of CNS and calculates the benefit with an algorithm. In order to estimate benefit of travel time saving of CNS, this study used UTIS data which is urban transportation information system. In the analysis, we calculated unit of travel time saving in Seoul. Unit of travel time saving resulted at 60.21 seconds per person, and travel time saving benefit of CNS estimated at 3,469 million won per year. In order to examine the accuracy of the benefit, this study verified UTIS data used in this study. As a result, the error between actual travel time and UTIS travel time data is less than 10%. In addition, a paired T-test was taken to prove the accuracy of UTIS travel time data. Consequently, this study can contribute on creating formalized analysis tools to analyze the effect of CNS.

Depression of Housing market along with global financial crisis is becoming an international issue, and South Korea and Seoul Metropolitan Area is also not an exception. Interestingly, the quality of unsold new apartment is differented between si, gu and gun in seoul-metro area. Besides, The pattern of unsold apartment is differented between unsold by presale and unsold completed units. Paying attention to this point, we perform Hot-Spot analysis and estimates coefficient based on 66 counties penal-data from 2001 to 2009. Result of this analysis shows that factor which causes unsold units is different depend on presale and unsold completed units. In addition, each hotspot pattern of Si Gun Gu (city, county, district) is observed to be different as well. In conclusion, Based on understanding about unsold by presale and unsold completed units, In conclusion, it is needed to come up with diffrentiated measure based on understanding of state of unsold apartments status in both period, before and after construction.Measure to settle unsold apartment issue in the metropolitan area is also needed to be prepared.

Advances in information and communication technology have made telecommuting a viable option for more and more workers over time. Therefore, several studies have been made on the impacts of telecommuting on urban form and travel behavior in the planning research field. Against this backdrop, this research synthetically examines the theoretical background and empirical evidences focused on the two main issues: 1) the relationship between home-based telecommuting and urban form, and 2) the relationship between home-based telecommuting and travel demand. Our literature review indicates that even though many researches have been made on telecommuting impacts, little is known about the causalities between home-based telecommuting and residential location, and the secondary impacts of home-based telecommuting on travel behaviors via residential location. Moreover, previous empirical studies have not consider the job locations of telecommuters. Therefore, this paper suggests the Structural Equation Model, which embodies the causal relationships among the telecommuting, residential location, job location, and daily Person Kilometers Traveled(PMT) variables, for the framework for future research. We expect that this conceptual model will be able to be applied in the future empirical studies focused on Korean cities.

Excess commuting has been extensively examined over the past two and a half decades, but it has been argued in the previous research that the inconsistencies of spatial analysis zones could cause the variance in excess commuting estimates. This is related to the Modifiable Areal Unit Problem(MAUP) that addresses three main effects: (1) scale effect; (2) zoning effect; and (3) boundary effect. Among them, the first two effects have been investigated in the previous studies but the impact of the boundary on the results of excess commuting is still unknown. This study aims to explain how the position of city boundaries changes the estimation of excess commuting. A case study of the Daegu and Gwangju areas provides an ideal example for examining the subtle variations in the excess commuting estimates. The effects of changing city boundaries on the results of excess commuting are examined in relation to the discussion of monocentricity and polycentricity. Based on the results, this study argues that considerable variation in excess commuting in the previous literature needs to be understood in relation to different spatial structure and MAUP.

In this study, the existence of spatial housing submarkets in the Capital Region was tested using Self Organizing Map and Chow Test. The Self Organizing Map was used to form 9 large sized area-wide socio-economically homogeneous regional clusters and 44 middle sized area-wide socio-economically homogeneous regional clusters. To form the clusters, 13 socio-economic indicators of the 78 spatial administrative units in the Capital Region were used. One of the 9 large sized regional clusters, which includes non-Seoul spatial administrative units, was selected and, then, the stability of the coefficients of the hedonic housing price functions across the adjoining spatial administrative units in the cluster was tested using Chow Tests. The results of these tests showed that there exist spatially very disaggregated housing submarkets in this area. The results imply that we need to see the housing market of the Capital Region as intrinsically spatially disaggregated when we estimate hedonic housing price functions for this area and one should consider using Spatial Expansion Method or Geographically Weighted Regression which allows the spatial changes of the parameter values to conduct hedonic analyses about the Capital Region.

This study intends to estimate the initial rent cost for the university dormitory BTO(Build-Transfer-Operate) by the private partnership project. The cost can be estimated by three pricing approaches: consumer based, cost based, and competition based. The preliminary rent cost has been developed by cost and competition based pricing. And the initial rent cost has been estimated by consumer based pricing, where the Price Sensitivity Meter(PSM) and the Unique Target Point(UTP) method is implemented based on the survey questionnaire asking the students such as the willingness to pay the rent for the university dormitory. Research findings indicate that the private universities, financial investors, construction firms should review the project feasibility and adjust the conditions of the optimal size planing, quality, service and interest rates etc for the improvements of pricing method for the BTO project. It aims that the consumer-friendly decision making for the project feasibility can leads higher satisfaction of students and accordingly lower vacant ratio can make the financial status of project sound.
