The urban development, resulting from the economic growth that initiated in the 1960s, focused on outward expansion until the 1980s. However, beginning in the early 1990s, there has been a steady increase in the attention paid to the qualitative aspects of life. With increased income and awareness of quality life, citizens today demand for various good quality services. For them, urban public facilities are an important part of community life because the facilities have effect on their psychological comfort or satisfaction with residential area. Nevertheless, in reality, due to the lack of society's awareness of the importance and necessity of public facilities, not enough investment is being made in public facilities, failing to meet the growing demand for the facilities. This study examined the public facilities of provincial cities with focus on the number and total area size of the facilities, then compared and analyzed the facilities in terms of number and total area size. It is hoped that the findings from the study will encourage policy makers to increase support for public facilities, contributing to achieving the sustainable growth of cities.

Mine drainage from coal mines is mostly acidic, polluted and/or contaminated, even if its quantity has increased substantially during recent days. This causes two kinds of problems arising at mining districts; one is the environmental disruption and the other is insufficient water supply for living, employee's bathing and industrial purposes. In order to mitigate the aforementioned problems, a specific equipment of Korea type for mine drainage purification has been developed and its prototype manufactured, followed by its applicability tests implemented at mine site. The results of the tests indicates that the new equipment developed is much lower than and economical compared to, other existing neutralization facilities at home and abroad in capital investment at installation stage, the consumption of neutralizing chemicals at operation stage and the requirements of installation site. Whangji area where the prototype water treatment equipment is installed has been sustaining a short supply of usable water, especially in dry seasons and supplementing about 40㎥ of water brought from a location farther than 4km in distance to meet water requirements. The prototype water treatment equipment is however considered capable of providing compressor cooling water in sufficient amount from winter season In the future.

Nowadays, the humankind's lives are affluent enough and the modern medical cure systems have made the humans' lives much longer. In spite of the modern medical development, the chronic & regressive diseases are rapidly increasing ironically. In this regards, many countries endeavoring to rely on the traditional or CAM instead of Conventional and Modern Medicines. The late Steve Jobs who sought for the natural therapy for his pancreatic cancer was one representative example. Every countries are investing huge amount of money to become the leader in the CAM market. Moreover, by preoccupying the world-wide standards, each country is trying to grab the market monopoliy. In this thesis, I examined several coutries' CAM markets and their CAM development strategies. These strategies should be considered for the KTM development Strategy. Fortunately, KTM has doing the main role in the Korean CAM development strategy. But to become the world leader in CAM market, the governmental committee should be established and the Financial Investment and Aid Program should be followed. It is very important to obtain the world standards. To do so, the R&D capability should be enhanced also. The world trends in CAM should be scrutinized and the Government Agency - Scholartic Group - Research institute have to cooperate for the same target.

RFID is a technique that plays an important role in identifying and tracking the movement of objects by inserting small chips in objects. It is somewhat similar to bar codes from the various points of applications, but is hopefully considered to lead to tremendous development by solving the present drawbacks of bar codes such as slow identification. Speed, low rate of identification, limitation on the distance of identification and on the amount of saving capacity. Through the development of RFID technique, revolutionary growth is anticipated in the area of logistics and commodity distributional systems. Futhermore, the self processing RFID makes the communications between man and objects possible, and through which introduction of ubiquitous atmosphere will be accelerated. Therefore RFID is considered as one of the most attracting area of investment by developed countries as well as Korea. In this paper, we analyze the world wide tendency on RFID, and propose the conditions for activating RFID industry and also suggest directions for national strategy for diffusing RFID.

As sewerage works has become one of the major public works in Korea, the employment of advanced and more appropriate sewerage technology has become essential to improve the efficiency of sewerage works. During last 10 years, the Korean Government has made tremendous amount of investment on sewerage works so that treatment plants in 58 cities have treatment capacity which is equivalent to 52.8% of total daily sewage generation in Korea. This remarkable development, however, has heavily depended on one technology, the conventional activated sludge process as more than 95% of the existing plants employ this process, Recently, the Korean Government and local authorities have plans to introduce more appropriate sewage treatment technologies and research and development in this area has become very active. To encourage employing new and appropriate technologies, however, the proper technology evaluation and verification program for new process is needed. The public sector should play a key role in this program since the sewerage works is one of the major public works. In this paper, the technology evaluation and verification programs related with sewerage facilities in the US and Japan are briefly reviewed. The Innovatived and Alternative Technology programs which was operated by US EPA until recently and Environmental Technology Verification(ETV) program which was commenced in 1995 are introduced. The technology verification programs operated in Japan and also in Korea are also reviewed in this paper to propose a future direction for development of the appropriate evaluation and verification system.

At the moment, in Korea, over 90% of energy resources depend on imports, and nearly 60% of electric energy is produced using fossil fuel. Therefore, the government adopted the Climatic Change Convention and has implemented the RPS system since 2012 to actively cope with the dependence on imported energy, and to grow and expand the new renewable energy industry. This study examined the performance results of mandatory supply of solar photovoltaic energy and non-solar photovoltaic energy assigned to providers and the present state after implementation of the RPS system. As a result, the achievement rate in 2012 was 64.7%. Especially, solar photovoltaic energy showed a high achievement rate of 95.7%, whereas non-solar photovoltaic energy showed a low achievement rate of 63.3% due to several problems and was highly dependent on the government. In 2013, the burden of each provider has increased due to more mandatory supply and addition of unfulfilled supply of 2012, and the separate mandatory supply of solar photovoltaic energy established for protection of the solar photovoltaic market is restricting investment. Therefore, there is a need to assign mandatory supply in consideration of the available amount of each new renewable energy.

This study was carried out to evaluate the Life Cycle Cost(LCC) of three types of RTPV(Building Integrated Photovoltaic) systems-Glass plus Granite. Crystalline BIPV and See through Amorphous BIPV-which were vertically installed to generate the same power output(76 kW level). Initial investment costs. cost. savings and maintenance costs had been predicted during the period of analysing the LCC of three types of BIPV(Building Integrated Photovoltaic) systems installed for the purpose of evaluating the LCC. In case of cost savings, it had been analyzed by measuring the amount of electric power generated, reduction in lighting load and heat & cooling loads through simulation. From this analysis, it was predicted that the See-through amorphous BIPV offering cost saving advantages demonstrated the economical efficiency similar to the Class plus Granite when it is backed by more than 20 years of durability.

Seasonal variation of natural gas demand coupled with rigid and stable import pattern of gas represents the characteristic feature of the Korean Liquified Natural Gas(LNG) industry. This attribute has required a huge amount of investment for the construction of storage facility. Thus, to minimize the supply cost, it is legitimate to reduce storage requirement itself. In this study, we combine three alternative methods to deal with the storage requirement to minimize the supply cost. Those are (1) adding additional storage tanks, (2) inducing large firm customers, and (3) constructing gas-turbine self generation facilities. Methodologically, we employ the mixed integer program (MIP) to optimize the system. The model also consider demand and price-setting scheme in separate modules. From the results, it is shown that if alternatives are combined optimally, a number of storage tanks can be reduced substantially compared with the original capacity plan set by the industry authorities. We perform various sensitivity analyses to check the robustness of the results. The methodology presented in this study can be applied to the other physical network industry, such as hydraulics. The empirical results will shed some light on the rationalization of capacity planning of the Korean natural gas industry.

Recently, amount of cargoes from main ports in Northeast Asia have rapidly increased and as well surplus port development in same region corresponded with the boom in external trade that resulted from successful export-oriented economics strategy by China, Japan and South Korea. To cope with this business circumstances, a certain form of port alliance is desperately needed to provide a suitable service to customer and establish their countervailing power against the shipping alliance. Nevertheless, Incheon seaport has not made a definite port alliance system with main ports in Northern China yet. Thus, the purpose of this study is to identify the key success factors to form a port alliance through examining previous studies. We have benchmarked previous studies which are related to main ports in global region and the questionnaire on customers of ports. By studying this, we are able to suggest a few strategies for forming successful port alliance to enhance Incheon port's capabilities in the long term plan. As a policy proposal, this study suggests Incheon port and main ports in Northern China should construct a logistics infrastructure through mutual investment and provide an incentive system when the ocean carrier makes port call to both ports.
