The purpose of this research is to find a better knowledge service R&D management process. There are four basic characteristics in service : intangibility, inseparability, inconsistency, and no inventory. These intrinsic characteristics require us to change the traditional manufacturing sector based R&D management process. It is necessary to develop an effective knowledge service R&D management model to improve the competitiveness of the service industry and Korean economy. A model case knowledge service R&D has been performed to find a better R&D management model. The whole cycle of R&D process, such as planning, selection, performing, and evaluation has been reviewed by real experience. Several important aspects of R&D process are compared between manufacturing R&D and service R&D. A knowledge service R&D management framework has been suggested. The results of this research can be used for building a better service R&D management process.

Ultra-fine Ag line was automatically patterned to the extent of 10 ${\mu}m$ in width by slit coating on the $10^4$ $mm^2$ glass, which was pre-patterned as hydrophobic and hydrophilic zone by using hydrophobic material. The resistivity of Ag film was about $4{\mu}\;{\Omega}{\cdot}cm$.

Let m, n, r be nonzero fixed positive integers, R a 2-torsion free prime ring, Q its right Martindale quotient ring, and L a non-central Lie ideal of R. Let D : $R{\rightarrow}R$ be a skew derivation of R and $E(x)=D(x^{m+n+r})-D(x^m)x^{n+r}-x^mD(x^n)x^r-x^{m+n}D(x^r)$. We prove that if $E(x)=0$ for all $x{\in}L$, then D is a usual derivation of R or R satisfies $s_4(x_1,{\ldots},x_4)$, the standard identity of degree 4.

The authors report on the fabrication of thin film transistors (TFTs) that use amorphous indium-gallium-zinc oxide (a-IGZO) channel and have the channel length (L) and width (W) patterned by dry etching. To prevent the plasma damage of active channel, a 100-nm-thckness $SiO_{x}$ by PECVD was adopted as an etch-stopper structure. IGZO TFT (W/L=10/50${\mu}m$) fabricated on glass exhibited the high performance mobility of $35.8\;cm^2/Vs$, a subthreshold gate voltage swing of $0.59V/dec$, and $I_{on/off}$ of $4.9{\times}10^6$. In addition, 4.1” transparent QCIF active-matrix organic light-emitting diode display were successfully fabricated, which was driven by a-IGZO TFTs.

정부는 국가연구개발사업을 통해 매년 4,000억원 이상 신재생에너지 분야 R&D에 투자하고 있다. 본 연구는 신재생에너지 분야 정부 R&D 투자의 효율성을 측정하고, 비효율성의 원인을 파악하는데 있다. 이를 위해 2009-2011년 동안 정부가 신재생에너지 분야에 지원한 4,213개 R&D 과제를 대상으로 자료포락분석(DEA)과 통계검증을 실시하였다. 분석결과에 따르면 수소, 바이오, 연료전지, 태양광 등이 다른 신재생에너지에 비해 상대적으로 R&D 효율성이 높게 나타났다. 또한 대학이 기업에 비해 보다 효율적으로 R&D 과제를 수행하였으며, 기업 내에서도 중소기업이 대기업에 비해 R&D 효율성이 높은 것으로 분석되었다. 마지막으로, R&D 비효율성은 과다한 총사업비나 논문실적 저조보다는 주로 국내외 특허실적 저조에 기인한 것으로 확인되었다.

The world largest 21.3" LTPS LCD has been successfully developed using SLS crystallization technology. Integration of gate circuit, transmission gate and level shifter was successfully performed in a large area display. Uniform and high performance of high quality grains of SLS technology make it possible to realize a uniform large size LTPS TFT-LCD with half the number of data driver IC's that is typically used in a-Si LCD. High aperture ratio of 65 % was achieved using an organic inter insulating method which lead to a high brightness of 500 cd/$cm^2$.
