For the last several decades, it has been recognized that technology is a key factor in becoming an ADC and an advanced firm. So many countries and individual firms have been increasing investments on technology development. Especially LDCs including Korea choose technology transfer and transaction as an important alternative of their own technology development. To activate technology transaction and transfer, it is necessary to establish an technology transaction system, namely a Technomart that will make good connections between technology suppliers and technology buyers, and efficient functional linkages of supporting infrastructures including organizations and laws related with technology transactions. Therefore this study reviewed both the characteristics of technology transfer and transaction and a conceptual structure of a Technomart through a literature review. And then, the study analyzed the Technomart related laws including an intellectual property right, a copyright, a patent right, and electric transaction related laws. In conclusion the study proposed the development directions of the Technomart related laws.

B2C is not doing well in Asia and Pacific countries in comparison to U.S. and Europe. But there is misunderstanding of low growth of B2C electric commerce caused by cultural factor. Consumers in market are rational to decide their purchase according to total cost - market price and transaction cost. I examined this with data of Korea and U.S. Transaction cost in real market is less in Korea than in U.S. but that of electric commerce, it is much less in U.S. As a result, the choice of consumers in Korea is real market transaction while consumers in U.S. choose electric commerce.

The electric power industries are moving from the conventional monopolistic or vertically integrated environments to deregulated and competitive environments, where each participant is concerned with profit maximization rather than system-wide costs minimization. Consequently, the conventional least-cost approaches for the generation resource schedule can not exactly handle real-world situations. This paper presents a game theory application for analyzing power transactions and market design in a deregulated energy marketplace, where the market participants determine the net profits through the optimal bidding strategies. The demand elasticity of the energy price is considered for the realistic modeling of the deregulated marketplace.

We estimated the price range of electricity transactions under the prosumer system, considering the spread of renewable energy and the prospect of introducing a surplus power trading system between power consumers in Korea. The range (min/max) of power transaction prices was estimated by prosumers and consumers who could purchase electricity from utilities if needed. It is assumed that utilities purchased electricity from prosumers and consumers under a Time-of-Use (TOU) rate, trading at a monthly price. The range of available transaction prices according to the amount of power purchased from utilities and the amount of transaction power was also estimated. The price range that can be traded is expected to vary depending on variables such as the TOU rate, purchased and surplus power, levelized cost of electricity, etc.

기업간전자상거래 거래액은 그룹(항목)별로 다양한 원인에 의해서 거래액 결정이 이루어지고 있어 복잡성을 띠고 있다. 본 연구에서는 복잡성을 띠고 있는 전자상거래 거래액의 제 변인들을 파악하기 위해 패널 데이터를 이용한 연구 모형을 설정하고 이를 통해 기업간전자상거래 거래액에 결정적으로 영향을 미치는 제 변인에 대하여 조사, 분석, 검증한다. 본 연구는 7 그룹(제조업, 전기 가스 수도업, 건설업, 도소매업, 운수업, 출판, 영상, 방송통신 및 정보서비스업, 기타)을 분석대상으로 하였다. 분석기간은 2005년 1월부터 2009년 12월까지의 자료를 이용하였고. 기업간전자상거래 거래액을 종속변수로 설정하고 사이버쇼핑몰 거래액, 회사채, 종합주가지수, 신용카드 거래액, 예금은행 대출금리, 환율을 독립변수로 투입하였다. 기업간전자상거래 거래액 요인을 추정한 결과 사이버 쇼핑몰 거래액, 종합주가지수, 그리고 예금은행 대출 금리와 환율은 각각 유의적인 정(+)의 영향을 미치는 것으로 나타나고 회사채는 음(-)의 영향을 나타내는 비유의적인 변수이고 신용카드거래액도 정(+)의 영향을 미치지만 기업 간 전자상거래 거래액에 큰 영향을 주지는 않은 것으로 나타났다.

신재생 에너지원 등 분산전원의 확산에 따라 단순한 소비자에서 적극적으로 에너지 거래를 원하는 프로슈머에 대한 논의가 확산되고 있다. 프로슈머는 잉여 에너지 혹은 분산자원을 이용하여 생산한 에너지를 전력회사, 다른 에너지 사업자 및 타 수용가에 판매할 수 있는 새로운 형태의 소비자이다. 이러한 개념을 지원하기 위해서는 프로슈머의 거래를 지원할 수 있는 기술과 플랫폼이 필요하나 이에 대한 연구는 시작 단계에 있다. 본 논문은 거래기반 에너지 관리를 위한 대표적인 기술의 비교분석을 통하여 향후 거래기반 에너지 관리 기술의 진화 방향에 대하여 검토하였다. 아직 거래기반 에너지를 충실하게 지원할 수 있는 기술이나 표준은 정립되지 않은 단계로 기술간 경쟁을 통해 지속적으로 발전해 나갈 것으로 예상된다.

Interstate electric power system, as an alternative for energy cooperation under regional economic bloc, has been hotly debated before progressing the restructure in electric power industry and rapidly expanded in many regions after 1990s. Especially, since northeast asia has strong supplementation in resource, load shape, fuel mix etc., electric power system interconnection in this region may bring considerable economic benefits. Moreover, since Korean electric power system has a great difficulty in a geographical condition to interrupt electricity transaction with other countries, it has been expanded as an independent system to supply all demand domestically. As a result, Korean electric power system makes considerable payment for maintaining system security and reliability and expands costly facilities to supply a temporary summer peak demand. Under this inefficiency, if there are electricity transactions with Russia via the North Korea route then economic electric power system operation nay be achieved using seasonal and hourly differences in electricity price and/or load pattern among these countries. In this paper, we estimate price cap of transacted electricity via interstate electric power system in northeast asia. For this study, we perform quantitative economic analysis on various system interconnection scenarios.

As the construction of renewable energy generators is on the rise and gets bigger in size, researchers pay more and more attention to the impact of such facilities on the power market as well as on the stability of power grid system. In Korea, while studies on the latter, including calculating the marginal capacity of renewable energy generators, is being made, those on the former has not yet been performed. As such, this paper analyses the impact of a big renewable energy generators on the price and transaction cost of domestic power market and proposes ideas to minimize such influence by applying the technology of forecasting renewable energy.

This paper deals with the design and the characteristic analysis of a coreless axial flux permanent magnet (AFPM) motor. Because a direct-drive wheel motor is easily derived from it, the AFPM motor is very suitable for application in an electric scooter. Compared to a conventional motor of the same size and weight, the AFPM motor is proven to have more power and torque per unit weight. In this paper, an AFPM coreless motor with a double-sided rotor disk equipped with Nd-Fe-B rare earth magnets is designed and a prototype of the motor is manufactured, which will be properly applied for the low-speed, and high-torque direct drive required for the electric scooter. The manufactured prototype of the motor has a rating of 300W, 510rpm, 5.6Nm, and 85% efficiency.
