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 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.

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.
