  • The objective of this study was to establish Facility classification for military barracks among military facilities. The military barracks are the place where soldiers spend most of their time. Thus, a new type of space in military barracks is required to improve the quality of life of the soldiers and make the military more advanced for national defense. The research method was to derive problems through a survey of the previous literature and case studies and to select target places in the Army, Navy, Air Force, and Marine based on the derived problems. An improvement scheme was proposed by developing criteria for military barracks spaces through a questionnaire survey. The following results were obtained: Facility classification inside of national defense military facility standard should be reorganized. The alternative plan is demanded for some camp which has no need about setting up the office facility. And the study of reasonable facility area after improvementing facility categorization is required.

  • In recent farming communities, the international open-economy tendency has been accelerated, and they are in the situation where they cannot but compete against international producers and markets. As a means to survive in this competitive era, a systematic agricultural information system is required to be established. Accordingly, in recent Korean agricultural communities, it's been regarded as an important alternative to provide and construct agricultural facility and to build an information system to maintain and manage them. However, in reality, the agricultural facility has not been constructed systematically enough, and the information system for the users of the agricultural facility has not been sufficient enough. Therefore, this research aims at analyzing the demands of users which might help establish the agricultural facility information system, and at providing information by suggesting what information the users of an agricultural facility information system want. Once the agricultural facility users are provided with some necessary information, the construction process will be more systematized, a structural safety will be secured by the construction by a professional enterprise, and the cost burden has to bear for users who can be effectively decreased by actively reacting to the natural disasters on the facility.

  • Disposal cover as an engineered barrier of a near-surface disposal facility for low and very low-level radioactive waste is composed of a multi-layer to isolate radioactive waste from environmental influences for the long term. To acquire a realistic forecast for the post-closure period of the disposal facility, it is essential to carry out long-term experimental research in a similar condition to the actual disposal environment. Hence, a performance test facility of the disposal cover was constructed in Gyeongju low and intermediate level radioactive waste disposal center in 2022. The constructed performance test facility has differences from the material properties presented in the design. These differences are factors that affect the prevent rainfall infiltration, which is one of the important roles of the disposal cover. Therefore, in this study, a numerical simulation of rainfall infiltration into the performance test facility was performed for the designed case and the actual constructed case. To simulate the behavior of water infiltration, the FEFLOW software based on the finite element method is used. Through the analysis of numerical simulation results, it is confirmed that the hydraulic conductivity of the material constituting the multi-layer of the disposal cover greatly influences the amount of water infiltration.
