After industrialization has been started, mankind needs and consumes more resources. Now, the resources depletion is a serious problem in the Earth. However, there are infinite resources in the Space. Especially, the Moon is the closest planet and has much resources, including Helium-3 and rare earths, which are needed to human being in the future. Humanity needs to reside on the moon to harvest these resources. For the resident, much resources, such as food, construction, and industrial materials, are needed. However, to transport these resources to the Moon from the Earth, an astronomical cost should be consumed. Thus, research is underway to support human activities by procuring resources locally. This is called In-Situ Resources Utilization (ISRU), which is the essential technology for the space development. In this paper, the reason why ISRU is essential and the its status are introduced and future research projects will be explained.

This study aims to determine the necessity, role, utilization, and operation and management plan in relation to the underwater space platform where humans can newly reside. It provides a comprehensive opinion on the need for creating undersea space and operation plans based on opinions of industry-university-affiliated organizations involved in the R&D project of the Ministry of Maritime Affairs and Fisheries for the utilization of undersea space and external experts participating in marine technology development. In this study, a survey was conducted on researchers participating in the construction of a Korean submarine space platform. FGI was conducted on marine technology development experts. Results were then derived. As a result of the analysis, the need for subsea space construction was found to be high. As for the role of subsea space, the most common opinion was to develop technology for utilizing subsea space and to secure marine science research functions. It was found that the creation of subsea space would have a positive impact on the domestic industry, especially the deep-sea development industry and the shipbuilding/offshore structure industry. In terms of utilization, after the end of the seabed space test bed, the response to utilization as a marine observation base and marine ecosystem research had the highest proportion. As for expected inconvenience, discomfort in the psychological environment was the highest. Experts suggest that securing a continuous budget is most important for stable operation in the future and that securing a manpower budget is essential for itemized budgets. In addition, it was judged that it would be appropriate to establish a prior agreement from the time of the prior agreement and prepare a countermeasure before proceeding with the project in order to ensure ownership issues, consignment management issues, and cost issues when using the project after the end of the project.

Recently, mainly in downtown, there have been frequent safety incidents in underground space like ground subsidence and land sinking. Out of diverse coping measures, the government is carrying forward the establishment of underground space integrated map. As a core element of the underground space integrated map, the 3D geotechnical information is used as major data of underground space impact assessment obliged in accordance with the "Special Act on the Safety Control of Underground Space Safety". The construction method of 3D geotechnical information is drawn when establishing the basic establishment plan of underground space integrated map, and the continuous construction is performed by the Integrated DB Center of National Geotechnical Information. However, it is necessary to draw concrete measures with accuracy, efficiency, and utilization. This study drew the construction plan considering the accuracy, utilization, and efficiency of 3D geotechnical information for the support of underground space safety. For this, accuracy between elevation and underground level is compared using MVS and MakeJiban which are software to construct boring information with geotechnical information in geotechnical information portal system. In the results of general analysis, the milepost-based construction of whole strata in a lump would be the most suitable in the aspect of accuracy, utilization, and efficiency. Based on the results of this study, Plan to construct 3D geotechnical information will be pursued.

In order to increase the utilization of limited space in urban area, it can be a good solution to make use of underground space. For the last few decades, underground space systems, such as underground passages, subway stations, and underground shopping arcades, have been constructed in many cities all over the country. Despite of the advantages on the utilization of space in urban area, underground space systems have always been exposed to the risk of inundations resulted from severe rain storms. In this study, it has been examined to apply 2-D flow models (TUFLOW and FLUMEN) to establishing the preventive measures to the risk of flood. For the part with relatively complex configuration, such as a corridor junction, 2-D flow models present the detailed information about the effect of geometry on the inundation events and the temporal and spatial distribution of inundation over the space. From the result, it can be concluded that the 2-D flow model can be the effective implement for establishing the proper measure to the inundation on underground space systems, which generally have relatively long and narrow geometry with complex inner configuration.

This study aimed to present the possibilities that a variety of conversions can be made in terms of the spatial function through the situation analysis and in-depth case studies, focusing on the cases of the conversion of historic buildings. Literature analysis and case analysis technique were conducted as the research methods. For the literature analysis, the researcher selected 105 cases of conversion-type buildings by recombining and reanalyzing them to space functional changes; the SPSS PC+ 18.0 program was used as the analysis tool to conduct a frequency analysis and cross analysis. In-depth analysis was conducted to investigate the overview of the architecture, building history, spatial functional changes, space program, conservation value, and the conserved parts by selecting 9 cases in Korean and foreign countries that have been recently converted through literature analysis and the results of the study were as follows. 1) As a result of analyzing the changes in function, the highest percentage of the cases was conversion into the cultural function (63.8%). 2) There were cases for conversion into the commercial function, business function, accommodation function and educational function besides cultural function. 3) As a result of spatial program, the attempts to increase the utilization of the building generally by applying the complex space with more than two functions could be seen. 4) The buildings with historical and architectural value were conserved most of the outer wall and some portion of internal parts; the buildings with symbolic value were renovated largely, while preserving symbolic parts; and the buildings with practical value were renovated in a way that maintains the structural parts while changing the interior space to be suitable for their function.

Prior to the concrete and practical use of closed schools, this study was designed to identify trends in the use of closed schools, and the possibility and direction of the library's use of closed schools based on the status of closed schools and use cases. As a result of the case analysis, the building of libraries using closed schools can be reborn as libraries with different characteristics from general public libraries, such as providing complex cultural spaces, eco-friendly spaces, and local community places. In addition, based on the results of the study, future direction of library closure is suggested as follows: Provide local economic contribution and local revitalization opportunities, life-friendly and friendly space for local residents, recycling space linked with elderly welfare, care service, urban to rural Immigrants, creation of added value and creation of local business using closed schools, environment-friendly space, recycling as a complex community center, recycled into a space that meets and complements local needs.
