전자책 산업은 인쇄문화와 정보통신의 융합이며, 새로운 비즈니스이지만, 우리나라의 시스템적인 변화는 역동적이지 않다. 세계적인 시장 플레이어들은 단말기, 플랫폼, 네트워크를 활용하여 회원제 또는 커뮤니티형 비즈니스 모델을 만들어가고 있지만 우리나라는 창조적인 콘텐츠 제작에 아쉬움이 많다. 단말기 또는 네트워크 서비스 등에 국한되어 있는 바, 본 연구는 다각적인 모델링의 가능성을 제안했다. 그리고 전자책 산업의 발전을 위한 전략적인 접근방법으로서 플랫폼 기술과 서비스 콘텐츠의 다양한 개발도 중요하지만 개발된 기술의 응용을 시사하고 있다.

In high temperature aircraft electronics, aluminium based brazing filler is the prime choice today. Aluminium and its alloys have compatible properties like weight minimization, thermal conductivity, heat dissipation, high temperature precipitation hardening etc. suitable for the aerospace industry. However, the selection of brazing filler for high temperature electronics requires high temperature joint strength properties which is crucial for the aerospace. Thus the selection of proper brazing alloy material, the composition and brazing method play an important role in deciding the final reliability of aircraft electronic components. The composition of these aluminium alloys dependent on the addition of the various elements in the aluminium matrix. The complex shapes of aluminium structures like enclosures, heat dissipaters, chassis for electronic circuitry, in avionics are designed from numerous individual components and joined thereafter. In various aircraft applications, the poor strength caused by the casting and shrinkage defects is undesirable. In this report the effect of various additional elements on Al based alloys and brazing fillers have been discussed.

Modern control theory and high speed switching device such as IGBT have been developed day by day, but it hardly has been applicated practically to the various fields of industry, specially power electronic fields, because there is no cost effective hardware that accommodates modern control theory. Thus, in our study, DSP based ultra high speed general controller which may be exclusively used for power electronic applications is developed.

Differential sensing methods are more effective in alleviating panel noise than single-line sensing, and thus have been increasingly used in the touch screen industry. However, they have a drawback: they tend to cancel out multiple touches and need touch position recovery algorithms. This paper introduces a novel algorithm of touch position recovery for differential sensing, which is a low-complexity but high-accuracy approach for determining multiple touch positions. We have implemented the proposed method in a touch screen controller system on a chip. In the simulation experiments using realistic touch screen models and a differential sensing circuit, the algorithm exhibited a high detection performance of a signal-to-noise ratio gain of up to 52.21 dB. Therefore, we can conclude that the proposed method is substantially more accurate than the previous method. Further, the proposed method incurs little or no overhead in terms of the detection speed and the chip size.

Recently, the automotive industry has been introduced to ISO 26262 in November 2011 to address the necessity of safety risk from sensor to actuator by providing guidance in the form of requirements and processes. The malfunctioning behaviour of these systems could have significant impact on the safety of humans and/or the environment. Most of the modern automobiles are equipped with embedded electronic systems which include lots of Electronic Controller Units (ECUs), electronic sensors, signals, bus systems and coding. Due to the complex application in electrical, electronics and programmable electronics, the need to carry out detailed safety analyses which focuses on the potential risk of malfunction is crucial for automotive systems. In this paper, the international trends on pre and post introduction of ISO 26262 through publications will be analyzed as well as to take a glimpse in the activities for implementing this standard by the automotive manufacturers. The issues and challenges which have been occurring from implementing this standard also will be highlighted.

To reduce the cost of solar electricity, the crystalline-silicon (c-Si) photovoltaic industry is moving toward the use of thinner wafers (100 μm to 200 μm) to achieve a high efficiency. In this field, it is imperative to achieve an effective passivation method to reduce the electronic losses at the c-Si interface. In this article, we review the most promising surface passivation schemes that are available for high-efficiency solar cells.
