    Using the Mobile Big Data for the Smart River Space Management : Data Validation and Water-Friendly Space Indicators

    Jongso Lee | Lee Sangeun | 2019, 101() | pp.3~18 | number of Cited : 6
    Abstract PDF
    While local governments implement various policies related to urban development and regeneration, welfare, culture and tourism, the river space, in particular, which river managers designated as water-friendly space, provides residents with opportunities for their relaxation and leisures. As a local resource, the value of the space continues to increase. Hence, river managers recently recognized necessities to manage and operate the river space in accordance with visitors’ demands, and to examine usefulness in applying mobile big data to improve the understanding of visitors’ demands. In these regards, the authors first validates the number of visitors obtained from mobile big data with several water-friendly space cases. The accuracy of mobile big data turns out to be quite good enough to significantly reduce river managers’ burdens in field surveys, although it remains to be improved further. By using various information that can be inferred with the data, the authors then define eight water-friendly space indicators. Those indicators seem very useful to understand how residents interact with river spaces. With all results, authors conclude that mobile big data and defined indicators have potentials as valuable data sources for river managers’ practices, especially, in making decisions upon classification of water-friendly space, establishment of convenient facilities, optimization of O&M budget, and deregulation on the river space use permission system.

    An Exploration of Intention to Homeownership of Renter Households Based on the Theory of Planned Behavior

    Oh Yeonkeun | Bang, Song-Hee | Lee, Young-Man | 2019, 101() | pp.19~38 | number of Cited : 0
    Abstract PDF
    The purpose of this study is to analyze the determinants of intention to homeownership of renter households by the Theory of Planned Behavior, which is one of the social psychological theory, with the data of Korea Housing Survey. According to the Theory of Planned Behavior, intention to homeownership is determined not only by the attitudes of homeownership but also by the subjective norms and perceived behavioral control about homeownership. The result of the analysis shows that intention to homeownership of renter households is influenced by the increase rate of neighboring house price and the DTI ratio. This means that the Theory of Planned Behavior also applies to intention of homeownership. Additionally we find that the rate of intention to homeownership in 2010 appears higher than in other years by assuming respondent’s affordability when asking housing intention in the 2010 Korea Housing Survey. Besides it is identified that the increase rate of neighboring house price by household’s age group affects intention to homeownership differently in a time of stability or boom of house price.

    The Effects of Greenbelt Release in Medium-sized Cities on Vegetation Conditions

    Jae Ik Ki | Lee Seomgyeol | Hyun Jun Yong | 2019, 101() | pp.39~48 | number of Cited : 0
    Abstract PDF
    This study intends to analyze the effects of greenbelt release on vegetation conditions in the case of the three medium-sized cities in Korea. For this purpose, two types of the difference-in-difference models are performed to estimate the determinants of the NDVI (normalized difference vegetation index) by utilizing the panel data of the study areas which includes both attribute data such as population and land price, and spatial data such as distance to the city center. The findings of this study indicate that the release of the greenbelt restriction made the vegetation condition worse off in all three medium-sized cities. This reflects that the greenbelt functions as a green area reservoir, and proves that the greenbelt restriction is an effective tool to control land development.

    An Empirical Analysis of Influential Factors of Spatially Exclusionary Residential Mobility in Korean Metropolitan Environments

    Minju Lee | In Kwon Park | 2019, 101() | pp.49~73 | number of Cited : 4
    Abstract PDF
    This study analyzes influential factors of such ‘Spatially Exclusionary Residential Mobility’ (SERM) in Korean large cities. Based on pooled data from the Ministry of Land, Infrastructure, and Transport’s (MOLIT) Korean Housing Survey, we analyze the factors that contribute to SERM through a multi-level ordered logistic model. The study finds that various regional factors as well as household characteristics influence SERM. Specifically, the study confirms the influence of regional mean of housing prices, apartment share, public rental housing supply, small-scale housing supply obligations, and activities of social enterprises. The results show that a high level of spatial openness for low-income households has a positive effect in mitigating SERM. Based on these results, this study calls for a continuous supply of public rental housing, a greater variety of housing types, more affordable housing for residents displaced by redevelopment projects, and the implementation of mitigation policies differentiated by region.

    A Study on Intermediary Organization to Manage Deteriorated Low-rise Residential Area: The Case of Neighbourhood Management Center in Siheung City

    Yang Keum-nan | Park Joon | 2019, 101() | pp.75~95 | number of Cited : 1
    Abstract PDF
    The purpose of this paper is to examine main features and limits of intermediary organizations and cooperative network system for the neighbourhood management of deteriorated low-rise residential area in Siheung and extract policy implication. Firstly, this paper reviews the case studies on resident-led neighbourhood management systems in deteriorated low-rise residental area of developed countries. Secondly, a case of the neighbourhood management center in Siheung is reviewed by in-depth interviews with local experts in urban regeneration, citizen autonomy, and social and economic business. It was found that the cooperation between the citizen autonomy association and the neighbourhood management center is crucial in Siheung as they complement the weaknesses of each other. From the interviews with experts, the importance of necessity of the participation of residents using appropriate technologies such as Apps on smart-phones and community business with sharing economy are emphasized. These are pointed out to enhance the capacity of citizen’s autonomy for revitalizing and managing the deteriorated residential area.
