RF 마그네트론 스퍼터링의 파워 ($50{\sim}150W$) 및 분압 ($2{\sim}10\;mTorr$)등의 증착 조건과 두께 ($50{\sim}1200nm$)에 따르는 Si 박막의 미세구조 변화와 그에 따르는 전기화학적 특성에 대하여 연구하였다. 파워와 분압이 증가할수록 미세구조가 거칠어지며 그에 따라 초기용량은 증가하였으며 두께가 증가함에 따라 사이클 특성은 감소하는 경향을 보였다.

This paper is compare to the enjoyment of way on Si-jo and Ga-sa in Lyric poetry. Si-jo and Ga-sa were created in Joseon Dynasty. Si-jo and Ga-sa is the Lyric poetry in traditional genre, representing Korea. These forms include the lyric genre but have a difference between the fixed verse and the long-poem in Joseon Dynasty. However, the two genres are the two genres had opened the possibility of communication from the very beginning in terms of gentry layer is the main writers. Joseon Dynasty those who enjoy the fixed verse and the long-poem, the literature of singing songs and reciting literature, in terms of the principle of metaphor and metonymy rhetoric will reflect the era of awareness and enjoyment of contemporary perception of reality characters. It can be said that performing Si-jo and Ga-sa of enjoyment fashion and work to compare with realistic about the versification principles but check ahead a lot of data, and add to the task of finding a logic that can explain clearly remain. This paper will have to complement the many points made in an attempt to unravel the complex issues in an integrated and comprehensive on-pronged approach and enjoyment of the fixed verse and long-poem Si-jo and Ga-sa and similar expressions are writing and testing the various parties of the enjoyment of culture in today's era of change in the 21st century can be the compass to navigate a new world culture.

This these studies on SiJo to be published Dongkwang magazine. Dongkwang magazine was published from 1926 to 1933 but in the concrete it proceeded for three years two month. It was published a little SiJo and SiJo would reflected a phenomenon of society and a character of literature. A representative characters of the Si-Jo in substance at that time was summed up three. First it described a warmth of farm village. Expecially make full use of a sensuous description expressed a landscape of farm village. Otherwise it revealed a life of austerity in farming area. Second it reflected a phenomenon of return to their home village. People who was familiar with their country loved to come back their old home. To relax their mind and body they came back home and they pursuit romantic life. Third it was a poetry of historical retrospect. Although their country was colonial situation they longed fot their country's independence. Because of this anxiety they expressed their heart by means of old sijo. Mainly using old castle, ring, historic site they revealed a hidden feelings thst they had. It was a sorrow, an eager, remembrance etc. In spite of a poor surroundings they sang hope, romance, an possibility of independence. and so SiJo reflected the phases of the times.

태양광 발전은 발전 셀의 특성상 태양광의 일사량과 태양과 셀 단면이 이루는 각도에 의하여 발전량에 차이를 가져온다. 태양전지의 표면의 입사각은 고정된 위치에서 태양전지 장치의 각도를 가변함으로서 변경 할 수 있다. 이 입사되는 빛의 각도를 변경하는 것은 효율개선의 한 측정의 방법으로써 사용된다. 본 연구에서는 입사각에 따른 a-Si/${\mu}$-Si 적층 태양전지의 양자 효율의 특성에 대해 분석하였다. 태양전지의 측정을 위하여 스테이지는 제작되었으며, 이 연구에서 양자효율 측정에 대한 유용성을 실험을 통해 입증하였다.

초미립 SiC분말과 SiC platelet을 2차성으로 Si3N4에 첨가하여 SiC/Si3N4 하이브리드 복합체를 가압소결로 제조한 후 2차상의 영향을 조사한 결과핫프레스법을 이용한 경우 SiC platelet은 Si3N4 기지 복합채의 치밀화를 저해하지 않고 초미립의 SiC 첨가는 Si3N4의 입성장을 효과적으로 억제하여 미세한 $\beta$-Si3N4의 grain을 형성함을 관찰하였다. 초미립 SiC첨가를 통한 복합체의 강도 증진은 상대적으로 $\beta$-Si3N4입자의 미세화에 의한 인성의 저하를 유도하나 SiC platelet을 첨가하여 급격한 강도 저하 없이 높은 인성을 갖는 하이브리드 복합체를 제조할 수 있었으며 SiC/Si3N4 하이브리드 복합체의 인성증진은 elongated $\beta$-Si3N4와 platelet SiC의 debonding에 의한 grain pull-out 영향임을 알 수 있었다.
