Bi_2(M_0O_4)_3 single crystal was grown by Czochralski technique. From the UV-VIS spectrum and the IR spectra Bi_2(M_0O_4)_3crystal was turned out having a indirect absorption process with energy gap, 2.8eV and having complicate absorption edge with maximum value in vicinity of 1860cm^-1. According to the crystallographic point group(2/m) and monoclinic system,Bi_2(M_0O_4)_3 crystal has two Raman active modes(Ag, Bg mode). Thus, the evolution of Raman spectra with temperature corresponding to selected experimental configuration-x(zz)y (Ag-mode), x(yx)y(Bg-mode)-was observed. From photoluminescence experiment, a violet-fluorescent light was observed. But we had a difficulty in analyzing the broad -spectra detected actually.

β-In2S3 and β-In2S3:Co2+ films were prepared on indium-tin-oxide (ITO)- coated glass substrates. X-ray diffraction spectra showed that the β-In2S3 and the β-In2S3:Co2+ films were preferentially grown along the (109) orientation. The crystal structure was defective spinel (tetragonal) with lattice constants of a = 7.62 Å and c = 32.33 Å for β-In2S3 and a = 7.89 Å and c = 32.91Å for β-In2S3:Co2+. From X-ray photoelectron spectroscopy, the binding energies of the In-3d and the S-2p core levels due to the formations of β-In2S3 and β-In2S3:Co2+ were found to be 445.28 eV and 162.13 eV and 445.82 eV and 170.05 eV, respectively. The optical energy band gaps, measured at room temperature, of the as-deposited β-In2S3 and β-In2S3:Co2+ films were 1.84 eV and 1.62 eV and those of the 400 ℃-annealed films were 1.7 eV and 1.84 eV, respectively. The dynamical behavior of the charge carriers in the β-In2S3 and the β-In2S3:Co2+ films were investigated by using the photoinduced discharge characteristics technique.
반부패청렴정책의 효과 분석: 서울시 청렴시책평가를 중심으로
이정주,이선중 한국행정학회 2012 韓國行政學報 Vol.46 No.3
본 연구는 반부패청렴정책이 청렴도 제고에 미친 영향에 대해 서울시 청렴시책평가를 중심으로 패널자료를 구축하여 분석을 실시하였다. 분석자료는 2008년에서 2011년까지의 서울시 25개 자치구의 청렴시책평가 자료와 국민권익위원회의 공공기관 종합청렴도 자료를 활용하였다. 분석결과 청렴교육·홍보, 행동강령의 내면화, 행정정보공개는 외부청렴도를, 청렴도향상 개선 노력도는 내부청렴도를 높이는 것으로 나타나, 부패통제시기를 기준으로 사전예방적인 요인이 청렴도를 제고하는데 중요한 영향을 주는 것으로 나타났다. 이는 오늘날 사전예방기능을 강화하기 위해 노력을 하고 있는 국제적인 반부패통제전략의 주요 흐름과 일치하는 것으로 평가할 수 있다. 하지만 새롭게 개편된 2012년 서울시 청렴시책모형이 사전 예방적 기능보다 지나치게 사후 처벌적 기능에 초점을 둠에 따라 이에 대한 개선이 필요할 것이다.

In this paper, I investigate the art of Miro, who is a great modern painter, and his influence on the 20c painting. Miro once had participated in Surrealism. His art contributed to the abstract painting as well as the concrete painting. By distorting, simplifying and transforming forms he tried to find innocence, which most of the paintings lacked in those days. His works give us fantastic and symbolic mood by forms and symbols. The free colors, pictures and automatic lines composes the works which win the sympathy of people. In addition, his investigation on unconsciousness, subconsciousness and psychoanalysis had an important influence on the world of painting.
