In this study, the author suggests utilizing unsold and unused land as temporary commercial parking lots as a way to raise funds for active public transport use. In addition, reasonable parking fee scheme is suggested by estimating marginal parking fee and marginal parking distance for the commercial parking lots based on the CVM. The author conducts a survey to investigate citizens' opinion on utilizing unsold and unused land in the urban development project area as temporary commercial transport facilities such as parking lots. Based on survey outcome, travel behavior and requirements are analyzed and marginal parking fee and marginal parking distance are estimated through the Contingent Valuation Method (CVM). The results are as follows: in the single-bounded dichotomous choice model, people are willing to pay 216 KRW for 165m in average for 10 minutes and their willingness to pay goes down against reaching distance to the parking lots from 365 KRW for 50m, 295 KRW for 100m, 173 KRW for 200m, and 51 KRW for 300m; in the double-bounded dichotomous choice model, people are willing to pay 285 KRW for 165m in average for 10 minutes and their willingness to pay goes down as well against reaching distance to the parking lots from 310 KRW for 50m, 297 KRW for 100m, 272 KRW for 200m and 248 KRW for 300m. It is clearly appeared that people's willingness to pay goes higher as distance to reach the parking lots goes shorter.

In order to present the enhancement direction for the military administrative facilities, that can satisfy the user demands and achieve cost-effectiveness the goal of public projects, this research analyzes the features of functional spaces using Analytical Hierarchy Process(AHP). Basically, the scope is selected to four facilities commander office, private office, public office, and meeting room, because they have an effect on military administrative facilities. Since the space is established by a combination of their own functions, this research begins with an analysis of functional spaces of military administrative facilities, which is verified through literature review and interview with expert. Thereafter, an AHP survey is conducted to military personnel to analyze the priority of functional spaces and to re-classify the functional spaces of each Military administrative facilities. Resultingly, the difference of functional spaces preference according to ranks and facility type are identified. Even though the same military facilities, it means that user satisfaction is different. Therefore, user satisfaction should be considered for each facility at the construction plan. It can minimize overlapped and unused spaces, which can help ensure cost-effectiveness. Consequently, this research suggested the methodology and the process that can take user satisfaction and can support the enhancement of military facilities standards.

In this study, we have evaluated the hazardous factors of fires such as heat release rate, smoke density, ignition temperature, and flammability of carpet and curtain used in the public facilities. As a result of flame retardant treatment, the heat release rate of materials treated with flame retardant was lower than that of not treated. However, the smoke density of treated materials was higher than that of not treated. Also, we have investigated the fire characteristics of used and unused carpet. As a result, the heat release rate and the smoke density of used for 3 years carpet were higher than those of unused carpet. The distinct differences of flammability and ignition temperature between used and unused carpet were confirmed.

Recently (2019), more than 3,800 schools have been closed in Korea due to the decrease in the number of students. Among them, 1,000 closed schools were used, 400 unused closed schools were sold, and the remaining 2,400 were sold. However, considering the absolute lack of elderly facilities due to the aging population, it seems necessary to recycle these public assets into elderly facilities. The purpose of this study is to explore the cases of remodeling closed schools in Japan and recycling them as elderly facilities, and to find ways to resolve the very serious shortage of elderly facilities while seeking measures to closed schools in Korea. The results of this study are summarized as follows: 1) In the case of Shinagawa in Tokyo, it was easy to change its use because the building was owned by the old district. 2) The existing classroom space was used as it was to create an elderly living space consisting of two or three rooms and one bathroom unit. 3) In case 2, even if the earthquake-resistant structure was reinforced, the overall construction cost was reduced by 30% compared to the new construction.

This study has proposed a methodology to detect suspicious facilities that occupy national and public land by using the cadastral and digital maps. First, we constructed a spatial database of national & public land based on the cadastral maps by linking its management ledger. Using the PNU (Parcel Number) code as a key field, the data managed by different institutions are integrated into a single spatial information DB (database) and then, the use or nonuse state of each parcel is confirmed on the cadastral map. Next, we explored the suspicious facilities that existed in the unused parcel by utilizing the digital topographical map. Then, the proposed methodology was applied for various regions and tested its feasibility. Through this study, it will be possible to improve the utilization of digital maps and to manage the national and public land efficiently and economically.

In recent years, there has been a movement to create a learning city where people can learn and enjoy what they want whenever, wherever, and whenever, so that the self-realization of individuals and the quality of life can be enhanced to improve the competitiveness of the city as a whole, It is becoming active. Many developed countries in the world are supporting projects to build learning cities by utilizing schools and public facilities, thereby providing local residents with opportunities for self-growth and solving community problems. In Korea, too, there are various programs using idle facilities. However, there is a lack of education programs for local residents and learning programs by partnership with local communities. It is when spatial and software strategies are needed to build a successful learning city. Therefore, we want to systematically organize the spatial data of the facilities that can be learned, analyze the current problems, and explore various ways to utilize them. We also analyze the programs that residents need to implement real and efficient learning cities.

Abandoned mines represent unused space resulting from resource use and changes in industrial environments. Efforts are underway to repurpose such underground spaces, leveraging their unique attributes of temperature stability, shading, and security. This study aimed to assess the feasibility of operating high-demand data centers and public sports facilities as potential recycling options for abandoned mine spaces. The status of data centers located in abandoned mines abroad was examined, including their operational technology capitalizing on the advantages of underground spaces. Considering the varying sizes of underground spaces in different types of abandoned mine in South Korea, the suitability of installing facilities for 12 different sports was evaluated for potential contributions to the health and welfare of local residents. The utilization of abandoned mine spaces as data centers and public sports facilities is expected to not only recycle industrial heritage but also to allow new development opportunities for local communities.

The purpose of this study is to estimate the available potential heat source for heat pump in the district heating supply area in the city. Unused energy potentials were estimated and integrated based on open source based data. In particular, geographical spatial analysis of recoverable heat energy density and heat demand in the heat source area of large retailers and public sauna facilities in the DH network located in the southern part of the metropolitan area (Pyeongtaek-si) was conducted. As a result of the study, the DH network area had a total potential energy of 1,741.7 toe/year for the two heat sources of large retailers and public saunas. It is estimated that 1,006.9 toe/year, which is 57.8% of the total, can be linked to the district heating. The large retailers showed a positive correlation with the floor area and energy use of 0.4937. The recoverable energy intensity was estimated to be $0.0017toe/m^2$ per unit area and $0.0069tCO_2/m^2$ for greenhouse gas emissions. In addition, public saunas were analyzed by comparing the empirical case with the theoretical calculation, and it was estimated that energy conservation estimate of 80% was $0.0315toe/m^2$ per bath area and $0.1183tCO_2/m^2$ for greenhouse gas emissions. The total potential energy amount of this area was positively correlated with the heat demand of apartment house by administrative district, and it was confirmed that it had a relatively high potential energy especially in traffic and commercial center.

This study was aimed at determining the characteristics of circular multi-family housing under the assumption that the shape of a residential building affects local identity. A total of six case studies were included in this study, three case studies on idle historical industrial facilities turned into residential buildings and another three on multi-family housing located in newly developed residential complexes. The study drew its conclusions as follows. First, the design of circular multi-family housing was intended to maximize security and defense from the outside in older times. This was later developed as the terrace house style with geometric urban squares designed under the urban planning of the Baroque period. This evolved high-density housing with a courtyard in the center offering a green open space, with the aim of restoring a sense of humanity. Second, the six case studies on circular multi-family housing were analyzed from the viewpoint of each factor of local identity, including historical and cultural, landscape, and community. Third, the historical and cultural elements of circular multi-family housing are found in some unused historical industrial facilities remodeled into residential buildings. They provide new capabilities and shapes desired by society at a given time, while maintaining familiar styles and elements of history, integrating a legacy of the past into the present. Fourth, circular multi-family housing with unique shapes and structures often become landmarks of a region with their distinctive appearance against a uniform urban environment and the monotonous scenery of residential complexes. They also show a high level of visual awareness with the distinctive shapes made possible when new elements are added to a historical exterior. Finally, circular multi-family housing with courtyards in the center prompt social contact between inhabitants, especially with dormitories and rental houses for the low-income bracket, which provide a small individual units with high use common space. Circular multi-family housing are planned in a manner similar to a small village or a city. They are designed to enhance sense of community, allocating various public amenities and provide cultural and commercial spaces on the ground floor and courtyard areas.
