    A Study on Improving Traffic Safety Evaluation Standard Based on Driving Simulators

    Hyang sook Lee , Joo Jaehong , Choo Sangho | 2014, 80() | pp.3~15 | number of Cited : 1
    Abstract PDF
    This study analyzed various methods to improve the evaluation standard of driving simulator operated by Korea Transportation safety Authority. First, we reclassified 23 dangerous driving types by considering related data and research, and applied them to the judgement method of driving simulator. Then, developed algorithms for deciding the level of danger of each dangerous driving type. As standard of dangerous driving, logical threshold value and human threshold value were established and compared. The comparison result indicated that difference between the two values occurs in some dangerous driving types, suggesting a reverification in the future through more elaborate field experiment. Finally, the research proposed a new evaluation standard and discussed how driving simulation results are provided to users effectively. This study can be utilized to establish the judgement method of other vehicles like buses, trucks.

    A Study on the Provision of Setting Permitted Building Use in Land Use Zone

    Kim Sangjo , Kim Dongkun , Lee Sunyong | 2014, 80() | pp.17~33 | number of Cited : 0
    Abstract PDF
    Building permission criteria by land use zone in Korea has been modified and changed with time and the change has made the zoning system distorted. This study started with critical thought that consistent basic principles for building permission criteria are needed although building structure types permitted in land use zone could be changed and modified according to contemporary paradigm of urban planning. The theoretical research concluded that the acceptance degree of the elements of planning (inducement coefficient of infrastructure, effects on the landscape and scenery, level of waste emission, and etc.) has to be considered before determining the division of zoning. Using data analysis, these elements were classified into 5 levels according to their degree of effects on the environment. Furthermore, the acceptable degree of the effects on the environment corresponding to each zoning was classified into 5 levels through expert survey. Ultimately, by matching the structures within the acceptance degree of the zoning, qualitative judgments were avoided as much as possible in determining the structures permitted per zoning. It would be reasonable to show the gap, because the result of this study is schematic and normative, so government policy should fill in the gap. Therefore, if government policies control the level of regulation as this study shows, they would achieve their goals within a range of principles.

    A Study on the Urban Spatial Structure Using Households Trip Survey: Focusing on the Case of Seongnam-si

    Mijin Joo , Kim, Seong Yeun | 2014, 80() | pp.35~48 | number of Cited : 10
    Abstract PDF
    The purpose of this study is to analyze the urban spatial structure in Seongnam-si by using households trip survey from 1996 to 2006. After the analysis, it was founded that in the case of external trips, travel to work in new town is related to Seoul while travel for shopping and leisure in old towns and new town is related to Gyeonggi-do. In the case of internal trips, it was analyzed that there is a strong relationship between old downtowns. While there is a weak relationship between old towns and new town. After the network analysis, it was also founded that centrality of some areas related to Bundang gu, new town, has increased. From the result, it should be concluded that Bundang gu plays a role as central place of travel for working, shopping, and leisure in Sungnam-si. However, if a city does not invest and redevelop old towns enough, spatial separation between old towns and new town will be increased. Thus, it is needed to prepare a comprehensive new town plan to invest and develop both new town and old towns together.

    A Study on the Risk Measurement and Determining Optimal Capital Structure of Project Financing on the Housing Market

    이경민 , Ahn, Ji-Ha , Jung, Chang Mu | 2014, 80() | pp.49~66 | number of Cited : 3
    Abstract PDF
    This study aims to empirically analyze the ripple effect of the project financing (PF) on private apartment housing to measure its risk, and present the optimal capital structure of project for sufficient absorb of the risk through simulation analysis. The result of empirical analysis showed that the increase of hosing PF project scale in certain region has positive effect on systematic risk of the region’s housing market, and the increase of construction company’s PF payment guarantee ratio has positive effect on systematic risk of company’s stock value. The result of simulation analysis showed that PF project requires 13% level of the ratio of owner’s equity on the standard of risk, and 23% level of the ratio of owner’s equity on the standard of profitability.

    The Characteristic of the Capital and Non-capital Apartment Markets Found through Cointegration Tests

    Imho Kang , Cho Youngjin | 2014, 80() | pp.67~81 | number of Cited : 5
    Abstract PDF
    This study aims to analyse the relationship between junse price indexes, between sales price indexes, between junse-sales ratios, and finally between junse and sales prices of Gangnam, Gangbuk, and six metropolitan areas, using cointegration tests considering lagged relationship of variables. The results are summarized as follows. First, junse indexes are strongly cointegrated nationwide. On the other hand, the sales indexes are cointegrated inside the capital and non-capital areas respectively, but not between the two areas. Second, junse-sales ratios are weakly cointegrated between the two areas. Third, junse and price indexes are not cointegrated with each other in the capital areas, but are in the non-capital areas. These findings imply that the nationwide apartment market can be divided into the capital area with unstable sales prices and the non-capital areas with stable sales prices, but generally can be viewed as one market.

    Items and Indicators of Evaluation for Decision of Priority in Improving River Water Quality

    Park Jong Seok , RHEE, KYOUNGHun | 2014, 80() | pp.83~100 | number of Cited : 7
    Abstract PDF
    This study selected the evaluation items and indicators of evaluation provided how to decide the priority of river water improvement and grasped the relative importance through stratification of the evaluation points through AHP technique exercised by group of experts. Below conclusion was acquired based on the study done. Firstly, for quantitative evaluation of the factors, it has been divided into 7 sections in the histogram based on the calculation of the average and standard deviation of each evaluation factor and each factor’s index has been calculated based on probability range of each section’s normal distribution. Secondly, the critically of the 6 evaluation sections applied in the classification model development to see the priority for river water quality improvement is in order of pollutant delivery load 29.3%, water quality 23.1%, flow rate 19.0%, density of the emission load 12.4%, emission load 10.5%, area 5.8%. Finally, the most important category among the 20 subcategories applied at the classification model is the flow rate being followed by BOD pollutant delivery load, TOC pollutant delivery load and Area. Being at order of TP density of emission load, SS pollutant delivery load, TN emission load, SS concentration showed to be relatively less important factors.

    Analyzing the Effects of Urban Agriculture on Housing Price: The Case of Creating ‘Pro-environmental Urban Farms’ in Gangdong-gu, Seoul

    In Kwon Park , Minju Lee | 2014, 80() | pp.101~116 | number of Cited : 12
    Abstract PDF
    This study aims to analyze the effects on housing price of urban agriculture in public community gardens (PCGs), using the case of ‘pro-environmental urban farms’ in Gangdong-gu, Seoul. We incorporated the difference-in-difference method into a hierarchical linear hedonic model to solve the problem of clustered data and to sift out the effects of creating community gardens from housing price changes over time and space. The results show that the opening of a PCG raises condo prices by KRW160,000~450,000/m2. In particular, condo prices rises much by KRW390,000~450,000/m2 in the 500~1,500m buffer of a PCG. But the price increase is not statistically significant in the 500m buffer. These results imply that municipalities should take into account spatial equity in benefits and costs when they raise and support urban agriculture.
