North Korean market created by reunification of the Korean Peninsula is expected to serve as a new growth engine to the already-developed construction industry of South Korea. Improvement on deteriorated construction facility of North Korea is a project in urgent need at the initial stage of reunification. Prior to market entry of the Korean peninsula under these circumstances, economic feasibility analysis on construction technology application must be preceded by considering reunification period. Therefore, this study conducts an economic feasibility analysis on construction facility improvement project of North Korea considering application period of technology developed by South Korea. Results of this study are expected to be utilized in future reunification process as the basis for establishing relevant guidelines for construction facility improvement project of North Korea.

In this paper, we tried to find the engineering feasibility of the component functions of the seven selected application technologies which are going to be installed on the next generation high speed train as the IT and smart sensor application technologies. The component functions of the seven applications, including the "Emergency or reminder notification", were identified and analyzed. In order to justify the feasibility of applications development, effect analysis and sufficiency analysis were performed. In effect analysis, how each function has an effect on safety, convenience, and efficiency of the passengers and attendants was evaluated. In sufficiency analysis, the importance and implementability of each function as a component was evaluated. The feasibility analysis was focused on the technical aspects of the functions. The following work will be the settlement of the final applications that are going to be designed and implemented. This will be done by studying the strategic feasibility in relation to the service or business of the high speed train.

The intent of this study is to investigate the feasibility of small-scale developments in residential blocks in the city, and to propose development strategies and models. This research is done on the premises that large housing developments ignore the urban structure of its own quality, whitens on-lot-based multi-unit housing developments fail to maintain amenity and livability in residential blocks. For solving these shortcomings, this research proposes the possibility of small-scale housing development models as an alternative development system. And some residential blocks were selected as case sites and analyzed into typical block types, to support the proposal of pertinent development types. Each type was investigated and discussed in terms of development feasibility and proper development strategies. Finally, three development schemes are proposed as prototypical models for the best application in residential blocks.

The short circuit current problem is one of the operational problems that need to be solved by power system engineers in Korea. It is an important issue in the Seoul metropolitan area especially because of highly meshed configuration. Currently, it is regulated by changing 154 kV system configuration from loop connection to radial system, by splitting of the bus where load balance can be achieved, and by upgrading circuit breaker rating. A development project for 154 kV/2 KA SFCL application to 154 kV transmission system after 2010 is proceeding. In this paper, a feasibility study of superconducting fault current limiter (SFCL) is carried out in Seoul metropolitan area to find out the effects of its application and feasibility. This study shows that it can reduce fault current considerably, and as it can minimize the upgrading of circuit breaker rating, the economic potential of SFCL is evaluated positively.

With the continuous development and progress of science and technology, the field of mixed reality applications has involved scientific research, medicine, entertainment, education, information dissemination, and people's daily lives; This paper will focus on the application of mixed reality in the field of education and teaching, relying on the characteristics of mixed reality technology. This article will use the combination of mixed reality and smart glasses to fully consider the characteristics of photography darkroom teaching, design and produce a mixed reality photography darkroom teaching software, and explore the feasibility of the application of mixed reality in teaching. This paper will use literature research methods, practical research methods, and survey methods as the main methods of research topics to determine the importance, feasibility, and necessity of the relevant theories studied in this paper. The application of mixed reality technology in photography darkroom teaching can not only solve many problems in the existing darkroom teaching methods, but also develop and expand students' Independent learning ability. It is concluded from this that mixed reality teaching software has the feasibility of sustainable development, which brings particular application value to the development and research of other education and art discipline software.

The SOC project such as road and railway performs a preliminary feasibility study according to the priority of the individual projects after establishing the master plans. For a preliminary feasibility study, feasibility evaluation should be performed according to the transport demand estimation and economic analysis. The feasibility of individual project will be performed by focussing on the results of analyzing economic feasibility. In case that analysis of the traffic demand and the economic feasibility every phase is performed, a lot of time and expense will be required in the course of promoting projects. So this study could give help to determine the priority of the project by intuitive method only in the phase to establish the master plan and a preliminary feasibility study.

In Korea, new total energy-saving solution has planned to build test-bed in underground subway station. Breaking energy is one of the most energy saving method in railway, but it has not be fully used up for economical purpose. This paper demonstrates on energy saving technology application including breaking energy and heating energy to underground subway station. It also offer solution of optimization of power energy flow. Moreover, economic feasibility analysis performed for undergound test bed constuction.

The construction industry is known to be one of the representative industries that generate fine dust. Therefore, reducing the amount of fine dust generated in construction sites is very important for the overall fine dust management. Based on this, this study proposed the concept of fine dust measurement and removal technology combined with advanced technologies such as drones and IoT. The qualitative, quantitative and risk elimination effects that can be expected when applying the proposed technique are analyzed. We will verify the effectiveness of the proposed concept through system development and field application, and evaluate specific economic feasibility through cost analysis. The proposed concept will be validated through system development and field application and evaluated specific economics through cost analysis.
