The automated construction machines have been recently developed to help solve the construction industry problems that significantly affect labour, productivity, quality, and profit. Despite the importance of performance analysis to commercialize the automated construction machines, previous studies have mainly concentrated on developing hardware and software of automated construction machines. This research now focuses on two objectives: (1) to propose an analysis model which can measure productivity, quality, and safety improvement rate of automated construction machines based on research and development (R&D); and (2) to develop a performance analysis system which will aid the evaluator in analysing the performance of automated construction machines. Finally, it is anticipated that the effective use of the performance analysis model and computerized system will ably develop the high-performance, automated construction machines and establish the marketing strategy to increase not only the commercial value but also the upkeep and development of construction machines.

A femur occurs a fracture easily as it is broken, since it is surrounded at a thick muscle etc. But a problem of impediment by a reduction and a fixing still remains. An angumentation is recently used as a method of a fracture. We analyzed a various stress and displacement of a femur as a finite element analysis in this project. And we make certain that a profit of an augumentation existed from the result.

International contractors must consider the substantial risks related to unexpected foreign exchange fluctuation incurred by conducting their business and using foreign currencies in foreign countries. Most international contractors attempt to minimize foreign exchange exposure within a manageable range because it may influence the company's fundamental financial structure, reduce market value or profit margins, or disrupt ongoing and future projects. This research provides a qualitative study of existing foreign exchange exposure (transaction, operation, and translation exposure) and current & effective foreign exchange risk management in American and Korean international contractors, as they represent both new and long-time members of the global construction market. Finally, recommendations of techniques for new and existing international contractors to minimize and better manage foreign exchange risk will be offered.

For a commercial building, property managers play an important role in maximizing the benefit by reducing cost and increasing revenue in the operation and maintenance phase of the building. However, most of property managers are spending their time in monitoring facility managers who have little impact on cost reduction and maximization of operating profit. The industry practitioners have difficutlty in increasing the efficiency of thier work due to this work environment. In addition, both property managers(PMr) and facility managers(FMr) are dependent on the paper drawings and manuals, which can worsen the inefficiency and human errors are inevitable. This study aims to contribute to improvement of the current practice by developing a novel algorithm that autmatically links the facility information with 3D model, which can provide an efficient property management for commercial buildings.

To respond to global warming and climate change, Korean Government has implemented the GHG Target Management, which leads to a voluntary reduction in greenhouse gases from large businesses. Korean universities have put efforts on reducing GHG emissions and energy consumptions in the campuses, however, because of various activities and its characteristic of non-profit organization, establishing a long-term plan for reducing greenhouse gases is necessary. In this research, the Seoul National University's energy usage is analyzed and applicable technologies for reducing GHG emissions are extracted. Hence, three scenarios for performing the GHG Target Management are established. Proposed scenario is available for GHG Target Management and it would be expected to support decision- makings for reducing GHG emissions.

Tatami serves as a multi-functional flooring and furniture material in traditional Japanese houses, and Westerners use it with suitable arrangements. Some choose to sleep on tatami for health reasons, while others adopt the lifestyle of 'floor living' to solve the spatial problems in cities. In any case, people use tatami for practical reasons rather than due to a cultural preference. I surveyed 750 respondents, including 463 non-Japanese people, and conducted both quantitative and qualitative analysis. I also interviewed European vendors and users of tatami during 2022-2023. The results showed that non-Japanese customers, especially Europeans, wanted authentic tatami mats made of natural materials such as igusa and rice straw to ensure health and sustainability. On the other hand, Japan's tatami industry is shifting towards artificial, or alternative, tatami-like mats. Few authentic tatami rooms exist in Japanese homes nowadays, and producers of tatami materials are almost extinct in Japan. Chinese farmers who supply almost 80% of igusa to the Japanese market may also discontinue their trade because the production is time-consuming and yields low profit. This paper discusses the possibilities of continuously producing and selling tatami in and outside Japan.

The United States Department of Agriculture (USDA) funded collaborative project on The Economic Feasibility Analysis of Crop Cultivation Practice Project in Pirganj and Kurigram Districts in Bangladesh will started during 2008-2012, for 4 years with total project cost of US$ 571,270. The project will be implemented in 6 villages; has 1,097 hectares areas which is divided into 948 hectares of agricultural land, 52 hectares of forest land and 345 hectares of other land, covered 1,059 households equal to 5,305 persons in Pirganj and Kurigram districts The project has proposed to be implemented in joint collaboration by Bangladesh Agricultural Research Council (BARC), Bangladesh Agricultural Research Institute (BARI) and Rangpur Dinajpur Rural Service (RDRS) Bangladesh with full participation of the farmers' groups of respective project site. The specific objectives of the project are: (1) to estimate the productivity of paddy, wheat, maize, tobacco and sugarcane (2) to determine the cost of production and returns to the above mentioned crops (3) to study the interrelationship between inputs and output of the above mentioned crops and (4) to examine the resource utilization patterns at farm level. In this project analysis, the net incremental profit is US$33,028. The expected incremental project benefit and incremented production cost are estimated as US$ 219,959 and US$ 186,931 respectively. The financial decision making criteria would be followed in this crop cultivation practice project. After the project implementation, the expected project benefits are assumed to be continued for 15 years. The benefit cost ratio (B/C) of the project is estimated at 1.077 (table 11) when using discount rate of 10% as an opportunity cost of capital in Bangladesh. FIRR of project is estimated at 26.15% which is bigger than the opportunity cost by more than double. So this project is financially feasible and acceptable. Therefore, this project should be extended to other areas to increase the farm income and economic growth of marginal poor farmers in Bangladesh.

This study is intended to develop an economic feasibility methodology of A/R CDM projects based on two project cases in China and Vietnam and to evaluate the project profitability from the view point of credit type selection between temporary CER (tCER) and long term CER (lCER) as well as from the aspect of CER prices by using indicators IRR, the year in which a single year profit is achieved and the year in which the accumulated deficit is cleared. For A/R CDM projects of industrial plantations, tCER is more suitable than lCER. Profitability of A/R CDM projects depend on the price of wood and CERs. In the case that the project participants take responsibility for replacement of credits to make the price of their CERs at higher levels, thus the project may not be feasible as a CDM project. However, minimum required tCER prices without replacement are 11US$/t $CO_2$, thus the project may be feasible under the future carbon market scheme.

France owns a unique film production process with the big share of public funding. In its background there is the most developed film support scheme in the world. We consider the French film industry has the fair competition order than any other country. This study follows the French film production process from the project planning to film screening. It looks into various aspects French cinema: production scale of French films, investment/production agreement, actors casting, decision of the film budget, major investors, staffs' wages and collective convention, screening, overseas sales and profit-sharing. It aims to get across the French film industry, especially the film production sector. As a case study, we choose a romantic comedy, Heartbreaker(L'Arnacœur) made in 2010. This study presents a French film industry structure. It will give you some hints to reconsider the existing problems of Korean film industry, for example, screen monopoly, vertical integration of conglomerates, poor secondary market, low earnings rate… etc.

In this study, we classified and analyzed the type and cause of resident conflicts and made a solution at side of resident through resident survey study for research subjects located at photovoltaic system will be installed or not. The factors of resident conflicts based on news media release from 2006 to 2018 were classified to four types such as economic, environmental, technological and procedural factors. According to the news analysis, the types and proportion of resident conflicts in the photovoltaic system projects showed 33% of economic factors, 32% of environmental factor, 21% of technological factor and 14% of procedural factor. This news analysis may suggest that it is very important residents to share the economic benefits as well as to ensure the fairness of the procedures for carrying out the project based on transparent information disclosure during the business promotion and profit distribution stages. We conducted the poll survey in the rural towns where photovoltaic system will be installed or not. The poll survey results showed that (i) there is quite difference in agreement rate and other recognition for sensitive matters such as profit distribution, environmental and technological factors whether photovoltaic system will be installed or not, (ii) the resident conflict regarding the photovoltaic system installation can reduce through direct involvement of residents process. To solve these resident conflicts, the local governments should mainly effort and consider the supporting technologies and consults to solve clearly resident conflicts. In addition, it has to advertise the safety of photovoltaic systems regarding electromagnetic wave which were within the range of scientifically harmless to the human body.
