    Yoo Hansol | Kim, Ikki | Kim Jonghak and 1other persons | 2020, 107() | pp.3~23 | number of Cited : 0
    Abstract PDF
    A Hyperloop is technically feasible as a future mode of transportation that moves at super high speed in a partial vacuum tube with little friction. Before realizing the Hyperloop, a network plan reflecting Hyperloop characteristics must be considered. Therefore, it is necessary to study the basic concept of the Hyperloop network design and its specific plan. The characteristics of the Hyperloop mode include high speed, small-capacity vehicles, and short headway in operational aspects. Considering these characteristics, this study proposes that the final Hyperloop network in South Korea uses a three-step process. The first step is to select cities that will be served by the Hyperloop. The second step is to determine the minimized cost network using the network flow mathematical model. The third step is to design the network; this step will utilize professional judgement and the results of the mathematical analysis. In addition to the network design, the final network was chosen based on network capacity, travel time reduction, and possibility of a cyclical network. The study suggested a network structure that included the Gyeong-bu axis, Ho-nam axis, Jung-bu axis, and Yeong-dong axis in South Korea when assuming that 20% of Hyperloop use will be mid-long distance trips. This network structure for South Korea can provide Hyperloop services to as many cities as possible while minimizing construction costs. In addition, it has an alternative route axis that can decentralize the demand generated by many cities to avoid insufficient network capacity.

    The Effects of Transportation Accessibility on Influx of Population and Gross Regional Domestic Product

    PARK JONG HOON | Chansung Kim | Lee, SeongWoo | 2020, 107() | pp.25~40 | number of Cited : 0
    Abstract PDF
    The purposes of this study are firstly to measure spatial spillovers of transport infrastructure investment on the influx of population and gross regional domestic products and secondly to present policy implications to enhance the effectiveness of the transportation infrastructure with respect to economic efficiency and balanced regional development. This study utilizes panel data that encompass 226 local autonomies from 2005 to 2016. This study utilizes the 2005 to 2016 panel data to investigate influx of population model and the 2010 to 2016 panel data to analyze the gross regional domestic product model. Through the application of the spatial panel model that best fits the spatial structure of our data, we were able to test our research hypotheses. Based on the findings, this study makes two policy recommendations. First, road accessibility should be improved to target whole regions for equity based on a balanced development strategy instead of concentrating on the nodal region. Second, an increase of railways in the nodal region is closely related to the efficiency gains of neighboring regions. A future policy to target the increase of railway accessibility to a nodal region should go along with an increase in road accessibility of neighboring regions that are connected to the nodal region.

    How Could Chamisul Village Community Last more than 10 Years?: Focusing on the Role Change of New Participants and Existing Members

    Kim HyeBin | Ju JongWng | 2020, 107() | pp.41~60 | number of Cited : 0
    Abstract PDF
    Recently, the government and local governments have gathered residents of the community to plan and implement various community-building activities for the village. As part of this project, a number of village communities have been formed nationwide. However, after the project is complete, a number of village communities were unable to continue their activities. Therefore, in order to understand how the Chamisul Apartment Village Community, which was formed on the basis of the village community support project in 2007, has been sustained, this study analyzed the participation structure of village community members and the changes that took place after the formation of the village community. According to our research, the Chamisul Village Community attracted and organized the residents with the educational training program. In addition, community activities were being carried out through various participation methods so that individual members of the community could demonstrate their capabilities. The community could sustain itself through the active participation of the newly organized resident groups and through changes in the roles of existing members. It was possible because the community provided various pathways through which residents could participate.

    An Assessment of the Effect of the Relocation of Public Institutions to Local Innovation Cities on Regional Growth

    Cho Gyumin | Sohn Dong-wook | 2020, 107() | pp.61~78 | number of Cited : 0
    Abstract PDF
    Various problems have been raised in Seoul metropolitan area due to the overpopulation. To resolve the imbalanced regional growth problem, Korean government initiated the innovative city project in 2010s. Although 153 public institutions have been relocated to the innovative cities by 2019, the gap between Seoul metropolitan area and the local provinces has increased, and the population of the Seoul metropolitan area exceeded that of the whole other regions in 2019. In this study, we analyzed the effects of the public institutes relocation to the innovative cities on the regional growth using three indicators (the number of registered population, local taxes and the number of employees). The analysis showed that the population concentration to Seoul metropolitan area has been steadily weakened for the last decade, but there was a lack of evidence on whether that was because of the innovative cities or not. Local tax indicators show that innovative cities had a highest contribution to the regional tax growth rate. Employment indicators also showed that there is a significant contribution of innovative cities to the growth of employment in the local provinces. Finally, it is suggested that the growth rate of individual cities and their contribution to regional growth should be measured together to make more balanced assessment of their performance.

    A Study on the Improvement of Heat Wave Adaptation through Questionnaire Survey on the Heat Wave Cognition in Busan

    Kang Ji Yoon | Jongbae Heo | Bongchul Park and 1other persons | 2020, 107() | pp.79~92 | number of Cited : 0
    Abstract PDF
    Abnormal climate events are increasing the risk of heat waves and causing economic and social damage. This study draws implications of the present heat wave cognition and responses from the result of the heat wave cognition survey, and establishes baseline data for the efficient countermeasures. The results show while the heat wave is seriously perceived to the most respondents, they do not aware the behavior against it. This suggests the necessities of the heat wave information delivery system and education of the emergency instructions. As eighty percent of the shelter visitors indicated the cooling effect of the shelter, it could help to efficiently reduce the heat wave damage through the operation of the shelters. Especially, to improve the effectiveness of the various countermeasures, currently being applied or planned, citizens’ awareness and use of those need to be increased, and this requires long-term effort of the central and the local governments.

    Analysis of Gradual-shift Causality and Volatility Transmission between KOSPI Index and Apartment Price Index

    Kim Sangbae | Lee Seung-A | 2020, 107() | pp.93~106 | number of Cited : 0
    Abstract PDF
    This paper investigates the price transmission and volatility spillover between the KOSPI index and the apartment price index in Korea. Unlike previous studies, we consider gradual shifts as a smooth process in causality and volatility spillover estimations (Nazlioglu, Gormus and Soytas 2019). To take the gradual structural shifts into account, we adopted an extended version of Toda and Yamamoto (1995) and the LM volatility transmission test by incorporating a Fourier approximation and the LM volatility transmission test. The estimation results from the extended Toda-Yamamoto model show that the apartment price index does not cause the KOSPI, but the KOSPI does cause the apartment price index. However, the results from the volatility spillover tests with the Fourier approximation show that there was no volatility transmission effect between the apartment price index and the KOSPI index. We believe that knowledge of the transition effect will help policymakers assess the risk to the real estate market. It could also help investors diversify their portfolios and make risk-averse decisions by allowing them to model incremental shifts.

    An Analysis of Factors Influencing Agglomeration Around the Information and Communication Industry Jobs in Seoul

    Hyeon Ji Yu | Youngsung Lee | 2020, 107() | pp.107~128 | number of Cited : 0
    Abstract PDF
    After the Fourth Industrial Revolution, the significance of the information and communication industry has expanded, and the agglomeration and dispersion of jobs within the industry are expected to show a new trend. In terms of industrial location, several previous studies on the location of the industry identify the trend in which jobs have been integrated and grouped into the places previously known for the information and communication industry. However, the recent development of cities and industries requires a job-oriented approach instead of an industry- oriented one. Thus, this paper notes the new trend of agglomeration and dispersion within urban job settings in the new industrial paradigm following the Fourth Industrial Revolution. It also identifies the factors and traits of cities that affect jobs within the information and communication industry. First, the overall imbalance of job openings within the information and communication industry in Seoul was identified, and a new trend of crowding around the areas of Mapo-gu, Jung-gu, Seongdong-gu, and Jongno-gu was shown. Second, the model’s rate of completion was improved by verifying the suitability through exploratory and confirmatory factor analysis. Third, it has been found that culture, food, and entertainment, which are related to tertiary locations, are influential factors for jobs in the information and communication industry. This paper identified changes after the Fourth Industrial Revolution in areas where the ratio of jobs in the information and communication industry is high, and it defined a new trend. In addition, the significance of this paper provides not only as influential in these jobs but also as what could be used to evaluate the level of a city is expected to help better policymaking.

    The Effect of the Residential Environment on the Residential Satisfaction: Focused on the Comparison of Public Jeon-se and Private Jeon-se

    Jeong Hyun | Moon, Sang Ho | 2020, 107() | pp.129~149 | number of Cited : 0
    Abstract PDF
    The purpose of this study was to analyze the effects of various residential environments on the satisfaction of the residents using a sample of SHift apartment residents in Seoul. A multiple regression analysis and structural equation model were carried out, and we compared the regression and path coefficient of public Jeon-se and private Jeon-se residents in order to understand the differences in the factors affecting the residential satisfaction of the two groups. As a result, only indoor and outdoor environments showed a significant positive effect on residential satisfaction in public Jeon-se and private Jeon-se residents. Physical factors, such as housing and locational factors, did not have an effect on the residential satisfaction of the two groups on average. The social environment had a statistically significant effect on the satisfaction of the residents depending on the Jeon-se type. In a group of public Jeon-se residents, multiple regression analysis showed that the social environment had a significant effect on residential satisfaction, but the structural equation model indicated that it had no significant influence. On the other hand, in the private Jeon-se residents group, the analysis showed that the social environment affected the satisfaction of residents.
