Research and development (R&D) is very important to acquire new knowledge in various fields. The significance of public R&D is also increasing, especially related to health policy making, establishing basic databases, and enhancing basic and clinical science. The total budget of general public R&D in Korea was approximately ten billon US Dollars in 2008, but the proportion of health care research was just below 10%. In private sectors, it was three times the amount allocated to the public budget. In this article, recent trends in public R&D in Korea, especially related to health care policy and biotechnology are summarized. A brief overview of the application process for a specific policy fund is also described for early-stage researchers in these fields.

Now, there are two big issues threatening global society, which are the depletion of fossil fuels and the environmental disruption. Therefore, marine diesel engine, taking up over 95% share of the marine power market, has met the environmental and economical problems, too. These problems have caused a necessity of new, alternative power systems in ships and fuel cell systems has been playing a central role as one of the alternatives. This paper analyzes the characteristics of marine fuel cell systems, R&D trends of advanced countries, and mapping out R&D strategy of Korea.

Emergence of the fourth generation mobile communication system (4G system) is now in its dawn. This article proposes a perspective framework on the 4G system, and discusses various kinds of system aspects and technological requirements in terms of novel service features, spectrum management, radio access technologies, wired access integration, core network, and mobile terminal. The focus of the article is to define the scope and features of the 4G system in an overall system/network viewpoint. From the foreseeable development trends, it is highly expected that whatever emerges in the 4G system will be some kind of constantly evolving and grand recursive concatenation of all the existing system/network developments.

As design trends has changed to have flexible aft hull structure, increased power output and stiffer shafting system, owners and classification societies have more concerned about shaft alignment. In the shaft alignment analysis, there are many uncertainties which are related in propeller generated force, bearing stiffness, crank shaft model and etc. in this study, it is focused on the effect of crankshaft model by comparing between equivalent model and actual crankshaft model.

변전소는 에너지 측면에서 볼 때 에너지를 연계하거나 분리 또는 변환하는 지점에 설치되어지며 변전소 자동화 시스템은 이러한 변전소의 주요 기기들이나 각 피더를 감시하고 보호하는 역할을 수행하게 된다. Microprocessor 기술의 발전과 통신기술 및 프로그래밍 기술의 발전을 통하여 변전소의 시스템 또한 90년경부터 디지털화가 가속되어 그 시스템 또한 구조적으로 변화하게 된다. 기존 아날로그 시스템의 경직된 구성에서 탈피하여 변화의 속도 또한 점차 증가하고 있으며 이러한 흐름을 파악하기 위해 변전소 자동화 시스템의 현재 발전 상황과 앞으로의 변화 방향에 대하여 서술한다.

Light elevated temperature induced degradation (LeTID) was noted as an issue in multi-crystalline silicon solar cells (MSSC) by Ram speck in 2012. In contrast to light induced degradation (LID), which has been researched in silicon solar cells for a long time, research about both LeTID and the mechanism of LeTID has been limited. In addition, research about LeTID in single-crystalline silicon solar cells (SSSC) is even more limited. In order to improve understanding of LeTID in SSSC with a passivated emitter rear contact (PERC) structure, we fabricated four group samples with boron and oxygen factors and evaluated the solar cell characteristics, such as the cell efficiency, $V_{oc}$, $I_{sc}$, fill factor (FF), LID, and LeTID. The trends of LID of the four group samples were similar to the trend of LeTID as a function of boron and oxygen.

최근 CPS(Cyber-Physical Systems)는 IoT(Internet of Things), 빅데이터 기술과 함께 미래 전력산업의 핵심 키워드로 등장하고 있다. CPS는 산업의 중심이 하드웨어에서 소프트웨어로 빠르게 전환하고 있는 현시점에서 기존의 물리시스템 혹은 물리프로세스를 효율적이고 안전하며 지능적으로 만들고 운영하기 위한 기술이다. 지난 2007년 미국을 중심으로 기술개발이 시작된 이래 다시금 새로운 전환기를 맞이하고 있다. 미국은 지난 2013년 제 2기 PIF(Presidential Innovation Fellow)의 주도로 SmartAmerica Challenge라는 이름으로 새로운 가치와 일자리 창출을 위한 국민생활 밀착형 대규모 CPS 융합 프로그램을 추진 중이다. 이를 통해 미국은 학술적이고 이론적인 CPS R&D 전략으로부터 보다 현실적으로 국부를 창출할 수 있는 개방형 R&BD형의 CPS 기술발전을 모색하고 있다. 본고에서는 CPS의 태동 배경으로부터 최근 SmartAmerica Challenge에 이르는 전반적인 CPS 기술동향을 조망하고 향후 우리의 나아갈 바를 제언하는 것으로 글을 맺고자 한다.
