Arleigh Burke(DDG-51) and Sejong warship are AEGIS destroyer of US Navy and Korea Navy. These are designed to make more than 30knots by applying a COGAG(COmbined Gas turbine And Gas turbine) system. However, the gas turbine(LM2500) in this system has a low SFC (Specific Fuel Consumption) when the warship operated low speed. So, many kinds of companies are researching the HED(Hybrid Electric Drive) system to improve this problem. The purpose of this paper is to analyze the HED system and simulate by Sejong warship data. Serveral methods were used for that purpose. More specifically, the equipment modeling are employed for regression analysis by LabVIEW. As a result, it was found that the warship installed HED system could cut their fuel bills by as much as about 80,000,000won per year.

In this paper, infrared image tracking techniques on complex cloud background is proposed. At the first, we determine size of target window using binary image, and then calculate sum of all pixel in the window while sliding on the absolute LoG(Laplacian of Gaussian) image. Each calculated result is mapped to a pixel of a sum map. By selecting the coordinates having the maximum value in the map determines the coordinates of target window. By implementation of infrared image tracking simulator, we confirmed stable tracking on complex cloud background.

A various ocean facilities are operating on the sea such as buoy, lighthouse, sea mark and drilling facility. Generally, buoy is the most inferior power condition fur operation, because it is received the electric power from stand-alone power system like solar system. The solar system fur buoy is influenced by weather condition, so the terms of power system design is very complicated. This power problem fer buoy is solved with solar and wave hybrid system. In this case, the output of wave system is reduced by marine life like mussels, barnacles and etc. This paper describes electronic anti-fouling system design for preventing the efficiency reduction of wave system in hybrid system.

본 논문은 지역혁신이 산업혁신을 통한 외형적 발전을 넘어 사회적 혁신을 통한 내재적인 삶의 혁신으로 확대 발전해야 한다는 인식하에 어떻게 하면 중앙정부를 비롯한 혁신 관여자들이 지역(지방)이라는 삶의 터전 개선, 즉 사람이 존재하는 그곳에서 혁신을 유도하고 촉진할 수 있는지를 찾아보고자 하였다. 디지털 전환 시대에는 전국적으로 고르게 지능화가 진행되어야 한다는 점에서 지자체가 주도하는 안정적 혁신조직 운영이 중요하고, 지역혁신을 위한 법·제도적 장치와 지역적 특성에 국가 지능화 전략 등을 결부시킨 정책 아이디어가 필요하다고 보았다. 기술적으로는 원격 경제, 플랫폼 경제 특성을 고려한 새로운 혁신 방정식이 필요하며, 지능화 기술혁신만이 아닌 국가 전체적인 디지털 전환전략과 연계할 것을 제안하였다.

This paper describes independent 6-phase BLDC motor which has a characteristic among BLDC motor used for electric propulsion system. Independent 6-phase BLDC motor has characteristics that phases of stator is independent electrically with each other and the phase of stator has more than 3 phases. We conducted simulation on independent 3-phase BLDC motor to analyze a characteristic of 6-phase BLDC motor. It is found that independent 3-phase BLDC motor has lower current pulsation and more stability in emergency situation than independent 6-phase BLDC motor.

Open R&D as new R&D methodology is becoming more important. The reasons are expanding the scope of IT industry, converging IT and other technologies as bio, nano, energy, environment, construction and so on, increasing the variety and scope IT needs, and intensifying the complexity of IT technologies. For such reasons, it is a urgent problem to make a new R&D system and R&D process under the economical, technological and political changes. To create a whole life cycle of open R&D system in NIS, researchers deeply understand the relationship of research activities such as planning, market survey, technologies, standards, and business model. We study on the cases of open innovation in public R&D sector. According to case studies, R&D in public sector will be changed efficiently as requested. R&D in public sector activity will be opened and collaborate with others such as universities, firms, and foreigner researchers. In this paper, we suggest the change`s directions of public R&D sector; (1) set up the new open concept and mind in R&D institutes, (2) the efficient R&D funding methods, and (3) openness in R&D platform. While we are encountering the new paradigm such as convergence and open R&D, this research will contribute to effectively create future R&D competitiveness. Also, the recommendation of new R&D system will be contributed to improve national innovation system and national wealth in the future.
