Recently, needs for the window cleaning for 2~5 stories in a building has been increased but existing window cleaning work by workers is not easy to clean the windows. Therefore a demand for development of alternative techniques have been raised. The purpose of this study is to analyze feasibility of development of the guide rail-type cleaning device for cleaning window for the lower stories. For this, we analyze the status of the job, such as risk, limitations of by workers and examine the potential producer needs through interviewing field experts of the cleaning work. Futhermore, we define the required features of the window cleaning device and proposed the validity of the relised device development of the function.

This study suggests how to evaluate the business model feasibility of Geographic Information Service(GIS) before they are commercialized in Ubiquitous Environments. It suggests the evaluation framework for business feasibility in order to provide a successful method. The framework is consisted of various evaluation dimensions and Indices like technology, marketability, business ability, customer satisfaction and business risk. From this research, we will anticipate a high rate of successful GIS business in respect to various elements related in the commercialization of the former business in ubiquitous environments.

This study analyzed the regional economic feasibility of greenhouse gases (GHGs) reduction technology in paddy rice. Firstly, the impact of GHGs reduction technology on productivity, emission reduction, and costs is different from region to region. Secondly, the water irrigation system contributes to productivity, GHGs reduction, and water reduction, but the profit of paddy rice will decrease because of increase in fixed costs and variable costs. Thirdly, the economic feasibility shows that water-savings plot has a 1.41 in a benefit-cost ratio.

Hydrogen is considered a key energy source to achieve carbon neutrality through the global goal of 'Net Zero'. Due to limitations in domestic green hydrogen production, Korean companies are interested in importing green hydrogen produced overseas. Because Australia and the Middle East possess high-quality renewable energy resources, they are attracting attention as suitable regions for producing green hydrogen using renewable energy. The cost of constructing and operating a green ammonia plant varies depending on the region. In this study, an economic feasibility comparison of green ammonia plant construction in Australia and the Middle East is conducted. Through this, it is expected to contribute to the economic analysis and feasibility analysis of the project to import hydrogen in the form of green ammonia into Korea.

The purpose of this paper is to investigate economic feasibility of creating artificial tidal flats using cost-benefit analyses. We assumed that the cost factors are associated with designing, construction and monitoring, and the benefit factors are associated with fisheries production, habitation, prevention of disasters, water purification, aesthetic value and existence value. First, for analyzing economic feasibility, the scenario suggests that a design can be made in a year, construction can be completed in three years and monitoring must be made for 20 years. Assuming the discount rate of 7.5%, economic feasibility analyses showed that B/C was 2.26 and IRR was 14.50. This study indicated there is economic validity of implementing creation of artificial tidal flat. In addition, we carried out a sensitivity analysis at the change of discount rate and restoration rate. The result of sensitivity analysis clearly showed that economic validity is low when discount rate is over 15%, and changes in restoration rate did not significantly effect on the economic validity.

The purpose of this study is to develop concept map as a tool of performance assessment in mathematics and to conduct feasibility test of the task. I developed and applied a concept map, an assessment tool, in the form of a mathematics performance task for 1st and 2nd year middle school students. I also conducted feasibility test of the task, and at the same time sought ways to guarantee reliability of the assessment procedure. Results of the task assessment can be summarized into the following four points. First, the concept map task was found to be appropriate for an assessment of mathematics in middle school. Second, results of all 10 factors on verification of validity of the content of the task were positive with over 50%. Third reliability of teachers who conducted marking of the four concept map tasks was high, all recording over .871 in correlation number.

This study is focused on the cases that Korean hotels stepped into international airports, public facilities, and successfully solved the contract related disputes by using arbitration in accordance with arbitration law. This case study on arbitration derives the hotel management strategy points as follow: 1. It must be a good chance for a famed hotel to step into international airports that have big publication effect. The feasibility study focused on marketing feasibility rather than finance feasibility may, however, not be good. 2. Written contract is required in entering into a contract with government organizations. However, oral contract still exists. 3. If the contract is made to always pay the higher amount between annual minimal guarantee and sales rate in expenses of store using charge, such contract shall cause very hard sales environment from the initial stage of the contract. 4. The airports have made optional contracts for national service. Such optional contracts are, however, not free from public criticism. 5. This case study is the first case study on arbitration applied to hotels. This study shall be, therefore, frequently referred to in setting a management strategy of hotels that want to run restaurants in another facility outside themselves.

This study aims to evaluate the feasibility of remodeling business by predicting the future price of apartment house after remodeling using Hedonic Price Model. The data concerning such 9 independent variables as location, unit size, unit plan, landscape, parking, the number of elapsed years after completion, number of units, mechanical performance, interior from 25 regions in Seoul metropolitan city were collected and evaluated by established evaluation criteria. The coefficients affecting the price of apartment unit were made by way of linear multi-regression and put into Hedonic Price Model. The feasibility evaluation model for apartment was made and verified by data of remodelled apartment. The predicted results using suggested evaluation model coincide with actual apartment market situations.

Over the past 10 years, South Korea has implemented various plantation projects including the Pine Restoration Project in Tujiin Nars and the desertification prevention forestation in Lun soum. This study has evaluated the implementation feasibility on the small-scale A/R CDM projects in Mongolia through which carbon emission credits can be secured. Characteristics, pros and cons, economic feasibility, and project execution feasibility were compared among three possible sites, Khyalganat, Tujiin Nars, and Lun soum. Among the three evaluated sites, Tujiin Nars has the better condition in tree growth, economic feasibility, and the applicability of experience than the other two sites. A/R CDM project in Mongolia, which has a great environmental benefit of combating desertification, is expected to have some effectiveness such as lowering costs from credit benefit, sustainable management by villagers, contribution to communities, investor's contribution to society and achievement of green image, and strengthening forestry cooperation between Korea and Mongolia.
