본 논문은 온실가스 저감 정책인 탄소세 정책과 배출권거래제 정책을 통해 창출되는 경제지대를 획득하기 위한 집단 간의 혹은 집단 내의 경쟁 상황을 분석한다. 집단 간의 경쟁상황인 탄소세 정책에 대해 구성원들이 결정하는 성과보수를 공시하는 경우와 공시하지 않는 경우로 나누어 분석하여, 배출권거래제 정책과 후생을 비교한다. 본 논문에서 나타난 결과는 다음과 같다. 첫째, 본 논문은 집단들이 성과보수를 공시하는 경우 집단 간의 과열경쟁으로 인해 탄소세 정책이 배출권거래제 정책보다 항상 후생이 작게 된다. 둘째, 집단들이 성과보수를 공시하지 않을 경우, 탄소세 정책의 집단 간의 경쟁이 완화되어 탄소세 정책의 후생이 증가한다. 만약 배출권거래제 정책의 오염배출권 거래량이 상당히 많은 경우에는 오히려 탄소세 정책의 후생이 배출권거래제 정책보다 더 크게 된다는 것을 보였다.

Recently, for the efforts of low-carbon deduction and to solve the problems of global warming, many industrial nations in world have been strengthening positively their competitive power into the research, development and industrialization of new renewable sources of energy and clean energy. In the most promising source of photovoltaic, it is essential that the government take an initiative role to develop and industrialize the materials, ingot or wafer, solar cell, power conditioning system and photovoltaic system, and need to establish both short-term and long-term technical development of goal setting and forward plan in the direction of the technical development strategy and forward industrialization for the strengthening of world market. This paper analyze new technology, policies and the market trend of photovoltaic field which are currently strategically and actively enhancing the research, development and practical-industralization by Korea and other nations.

Electric vehicles contribute greatly to energy conservation, $CO_2$ reduction and energy security through high fuel economy and various electric sources. Electric cars have a huge economic impact. More than 14 million hybrid electric cars have been sold worldwide. More than 3 million plug-in electric vehicles have been sold worldwide. The environmental impact depends greatly on the amount of national power generation, and as the electric grid becomes more and more carbon-intensive, countries are increasingly adopting hybrid and electric vehicles. Electricity is expanding beyond cars. Electric buses, trucks, and ships have similar benefits.

Purpose: The plant industry is a key order-taking industry that leads national industrial development through convergence and integration with various industries in all value chains from planning and marketing to financing, design and engineering, purchasing, construction, and operation and maintenance (O&M). Research design, data and methodology: The Korea government has been actively promoting overseas plant market development support projects to support large and public enterprises and medium and small enterprises. Results: The Korea government are working with the industry and the government so that the Korean plant industry can establish itself as a key driving force that provides the foundation for low-carbon and energy transition that our times demand and makes our world a better place to live. Conclusion: A high value-added industry that brings enormous profits and international fame to exporting countries. Korea is highly dependent on trade, should recognize the plant industry as a key national export sector.

The electrochemical CO₂ reduction (ECR) to produce value-added fuels and chemicals using clean energy sources (like solar and wind) is a promising technology to neutralize the carbon cycle and reproduce the fuels. Presently, the ECR has been the most attractive route to produce carbon-building blocks that have growing global production and high market demand. The electrochemical CO₂ reduction could be extensively implemented if it produces valuable products at those costs which are financially competitive with the present market prices. Herein, the electrochemical conversion of CO₂ obtained from flue gases of a power plant to produce diesel and formic acid using a consistent techno-economic approach is presented. The first scenario analyzed the production of diesel fuel which was formed through Fischer-Tropsch processing of CO (obtained through electroreduction of CO₂) and hydrogen, while in the second scenario, direct electrochemical CO₂ reduction to formic acid was considered. As per the base case assumptions extracted from the previous outstanding research studies, both processes weren't competitive with the existing fuel prices, indicating that high electrochemical (EC) cell capital cost was the main limiting component. The diesel fuel production was predicted as the best route for the cost-effective production of fuels under conceivable optimistic case assumptions, and the formic acid was found to be costly in terms of stored energy contents and has a facile production mechanism at those costs which are financially competitive with its bulk market price. In both processes, the liquid product cost was greatly affected by the parameters affecting the EC cell capital expenses, such as cost concerning the electrode area, faradaic efficiency, and current density.

Generation and physico-chemical characteristics of municipal solid wastes are very important for sanitary management. However, that has not been investigated so far especially in chunchon. And so, we tried to examine many things in detail. It was resulted that density was $90{\sim}94kg/m^3$ in school and office zone and $290{\sim}298kg/m^3$ in apartment and market place. The compositional weight fraction was food, 40~54%, paper, 14~18%, vinyl and prastic, 14~20% in house zone and market place and paper, 42~70% in school and office zone. Moisture was estimated to be 54~57% in independent house zone, apartment and market place and 11~23% in school and office zone. And three composition was water content, 44.1%, incineration particle, 11.2%, volatile parts, 44.7% in respectively. That is because of seasonal effects and regional chracteristics. In the results of chemical composition and caloric value analysis, carbon(C) was 80% in vinyl and plastic and oxygen(O) was 54.4% in paper.

With the pace of rapid innovation in technology of IoT (Internet of Things) and smart devices, biometric technology becomes one of the most progressive industries. Recent trends in biometrics show most are focused on embedding biometric sensors in mobile devices for user authentication. Multifactor biometrics such as fingerprint, retina, voice, etc. are considering as identification system to provide users with services more secured and convenient. Here we, therefore, demonstrate some major technologies and market trends of mobile biometric technology with its concerns and issues.

Depending on the industrialization, construction market has grown buildings are based on concrete will continue to increase. But the problems of environmental pollution come to the fore with the indiscriminate use of concrete and rapid development. In addition, carbon dioxide(CO₂) in the process of producing cement being emitted a large amount of has been caused a serious problem of environmental pollution. This trend is being actively conducted research to reduce the use of cement. In this study, eco-friendly materials, such as flats, Blast-furnace slag by mix and cement review the mechanical characteristics of the mudflats eco-friendly cement mortar to reduce the usability of the review were seen as a green building material.

The hydrogen economy is still a niche market and a new system. If we believe in the optimism and the hope of human history of technological progress, the hydrogen economy will be a new paradigm to replace the carbon economy. The research question is what kind of leadership the government should show in order to revitalize the hydrogen economy. In response to the research question, this study highlights the governance leadership. The new economy must be newly recognized before they can find a solution. This research can be the first step in finding the way.
