This paper reviews the one of problems that may occure for the tram operating in Korea, it's a free-riding problem, I analyzed the feasibility of combining the introduction of world-class technology solution "IT". It is under review the introduction of tram in Su-won city, Chang-won city, Wi-Rye new town. Free-riding is one of the biggest issues of any agency that operates the public transportation system. It has been acting as the main factors threatening the financial integrity of the operating agency, and the ratio of free-riding is further increased. In this paper, I want to build a foundation for the development of the system by analyzing the economic feasibility for the introduction of free-riding prevention system.

The purpose of this paper is to present a procedure for feasibility analysis of new hospitals. The major steps of the procedure proposed consists of determination of location for a new hospital, analysis of the community served, facilities planning, estimation of capital requirements and financial analysis. Technical details of the necessary analyses are covered by providing relevant information most of which is readily available in Korea. The procedure proposed in this paper can be applied not only for the case of the general hospital but also for the case of the clinic.

Through USN field Test Projects launched in 2005, 9 USN application service models such as u-Ocean, u-Construction, u-Farm, u-Hospital has been deployed. We conducted technical, industrial, economical feasibility tests to verify those services. This thesis will cover briefly the current situation of USN industry domestically and internationally. It will show the future prospect of convergence service model based on USN in conjunction with research details and results from previous USN field Test Projects.

This paper overviews the concept of the strategic niche management, which emphasises the social aspects of new technologies and calls for relevant government policies for socio-technical transition. Hydrogen energy technologies remain in the niche level, thus the SNM perspective is appropriate to be applied. The reason why, and the way how to see hydrogen as a socio-technical niche are discussed, followed by an analytic argument on hydrogen policies and their SNM characteristics. Final part of the paper deals the design of the socio-technical experiment. It is expected that this paper would contribute to not only policy development but also improving understandings on the socio-technical nature of hydrogen energy of hydrogen community.

Although much research has been carried out using recycled aggregates sourced from normal strength concrete, most of the buildings to be demolished are constructed with low strength concrete. Therefore, the properties of the concrete incorporating recycled aggregates, sourced from the waste of structural elements cast with low strength concrete, were investigated in this study. Four different concrete mixtures were designed incorporating natural and recycled aggregates with and without fly ash. The results of the mechanical and durability tests of the concrete mixtures are presented. Additionally, full-scale one-way reinforced concrete slabs were cast, using these concrete mixtures, and subjected to bending test. The feasibility of using conventional reinforced concrete theory for the slabs made with structural concrete incorporating recycled aggregates was investigated.

Crack sealing is a maintenance technique commonly used to prevent water and debris penetration and reduce future degradation in pavement. The conventional crack sealing operations are, however, dangerous, costly, and labor-intensive. Automating crack sealing will improve productivity and quality, and offer safety benefits by getting worker off the road. During the last two decades, several teleoperated and machine-vision assisted systems have been developed to automate the overall process of routing and sealing pavement cracks. However, the developed systems have not been commonly used in the construction sites because of the technical problems. Especially, the performance of end-effector, related to the productivity and quality improvement, is very important factor to improve the practical use of the developed systems. The main objective of this research is to develop an end-effector in automated pavement crack sealing machine and to analyze the technical feasibility of the developed end-effector.

The purpose of this paper is to investigate economic feasibility of manganese nodules in Korea area (Clarion-Clipperton Fracture Zone). We assumed that the production scale of manganese nodules were 3.0MT or 1.5MT and analyzed that the capital cost and operating cost were estimated in the four sectors, exploration, mining, transportation and metallurgical process. The capital cost and operating cost evaluation reflects the latest technical practices. First, for analyzing economic feasibility, the scenario suggests that the production of 4 metals can be made for 25 years. Assuming the discount rate at 8.0%, equity capital at 50% and tax at 27%. When manganese nodule were mininged 3.0 MT, economic feasibility analyses showed that IRR was 12.8 and pay-back period was 9.2 years, and when manganese nodules were mininged 1.5 MT, economic feasibility analyses showed that IRR was 4.0 and pay-back period was 11.8 years. This study indicated there is economic validity of at the product of manganese nodules 3.0 MT. In addition, we carried out a sensitivity analysis at the change of cobalt price on mining 1.5 MT. The result of sensitivity analysis clearly showed that economic validity is high at increasing of cobalt price 50% up.

The purpose of this study was to suggest an improvement plan ultimately to develop practical evaluation methods for national technical qualifications in the field of seeds and horticulture based on the National Competency Standards. Through this, national technical qualifications can be strengthened in terms of professionalism in the seeds and horticulture field. In order to conduct this study, the national technical qualification currently in use was matched to certain competency units and competency unit elements of National Competency Standards. We then visited an industrial site to understand the practical factors related to the technical, facility and equipment aspects of the seeds and horticulture industrial field, after which a practical evaluation exam was developed. Also, for a feasibility study, a pilot test assessment was conducted for students majoring in seeds and horticulture, with a survey also conducted with field experts and an advisory committee consisting of experts in seeds and horticulture. Based on the results, by suggesting an improvement plan for a practical evaluation method leading to better national technical qualifications in the field of seeds and horticulture, it was shown to be possible to improve knowledge, technical, and literacy aspects. This can lead to the training of outstanding technical professionals. Ultimately, the results here are expected to contribute to the improvement of the seeds and horticulture industry.

General aspects of deepwater petroleum exploration and production were identified and related technical challenges were addressed. Historical perspectives, insight, processes, and engineering applications are reviewed to enhance the design capability of the domestic offshore industry. The technical challenges and unique aspects of deepwater exploration and production were identified. The assessment of deepwater exploration, drilling, and production systems is a key stage for performing the front end engineering design (FEED). The global trends in deepwater development, including the feasibility for Korea, were reviewed.
