The development of blockchain-based art trading platforms has not been revitalized despite the recent recovery of the cryptocurrency market. In this paper, we found that blockchain-based art trading platform is not revitalized due to the large volatility of cryptocurrency price. As a solution, we propose a trading system using dual types of cryptocurrency that one is Stablecoin and the other is legacy cryptocurrency. Through cryptocurrency dualization, the proposed system can satisfy both user's requirements of stability of art price and value growth of the blockchain system. In addition, the proposed system is expected to be able to balance the use of dual cryptocurrencies and market capitalization ratios according to market principles. Finally, the proposed cryptocurrency dualization is expected to be used in other applications that require both the stability of the value of transactions and the growth of the value of the blockchain system.

What are the implications for us through the discussion on the effect of Germany's dual system of vocational education on the youth unemployment rate? You can find out what kind of evaluation Germany is receiving on the dual system vocational education system implemented based on the 'Vocational Education and Training Act' (Berufsbildungsgesetz), and the specific system establishment form for the industry-academic-government cooperation system. It was possible to present the crises and problems of these systems. Responsibility for the dual system of vocational education in Germany rests with the national and state ministries of education, and private enterprises and chambers of commerce are responsible for business practices. Practical work in a company is conducted through skill-oriented education, and in vocational schools, competency-oriented theoretical education is received. In addition, the necessity and demand for digital vocational and education training in accordance with German Idustrie 4.0 and higher vocational education degree acquisition through dual-degree courses were identified. It can be seen that the youth unemployment rate is the lowest in Europe due to the successful development and utilization of human resources to improve the competitiveness of companies, such as dual vocational education and training (VET) at all levels, higher vocational education at universities, and continuing vocational education programs. Vocational education in Korea will also be able to improve the unemployment rate by establishing a system that allows schools and businesses to conduct vocational education and training simultaneously. In particular, it was possible to judge the necessity of 'close consultation between labor, management, and government', which we consider the most important and should lead to in-depth discussion and cooperation for dual education between vocational schools and companies.

Vehicle classification system in Korea is operated by two different types depending on operating purpose and place. 8-category classification system operates in Expressway and Provincial road, and 11-category classification system operates in National highway. These different operations decrease the efficiency of practical use of gathering data. Therefore, this study proposes new-modified vehicle classification system for solving this problem. For classification, this study not only focuses on mechanic survey system which is based on vehicle specs, it's also focuses on the applicability of roadside survey. This proposed classification system considers the tendency to vary of vehicle types, and the compatibility with the other classification systems. This system might be the most suitable system for our present situation.

환원공정은 산업 전반에 걸쳐 매우 광범위하게 이용되고 있는 기술로서, 현재 활용되고 있는 환원공정으로 대표적인 것이 일반금속 및 비철금속 등의 열처리 공정이다. 열처리 공정에서의 환원공정은 적용되어지는 제품의 종류에 따라 차이는 있겠으나, 기본적으로는 제품에 적합한 경도 및 조직 구조를 형성하고, 공정 과정 중에 발생할 수 있는 표면 산화를 최소화함으로서 제품의 품질을 향상시키는 역할을 하게 된다. 그러나 기존에 적용되고 있는 이러한 환원공정들은 환원가스의 발생과 에너지원의 공급이 이원화되어 있어 비효율적인 시스템 운영 및 이원화에 따라 공급되어지는 에너지원이 이중적으로 소모될 수 있는 비경제적인 요인을 내포하고 있다. 반면 촉매 연소 방식은 이러한 기존의 단점을 보완, 극복할 수 있는 기술이다.(중략)
