CTAB(cetyltrimethylammonium bromide)-capped CdSe nanoparticles were prepared by using a 4 : 1(v/v) distilled water-isopropyl alcohol mixture. The cadmium chloride and sodium selenosulfate were used as the cadmium and selenium source. By the analysis of XRD and XPS, the resultant particle was confirmed to be cubic CdSe phase. TEM image showed CdSe nanoparticles with empty core. The CTAB-capped sample showed an maximum absorption at 418nm, blue-shifting compared with bulk CdSe, which indicated stronger quantum confinement effect compared with uncapped sample. From FT-IR analysis, it was found that the presence of the new peaks in the $850{\sim}1250cm^{-1}$ range indicated the existence of chemical bonding between CTAB and surface of CdSe nanoparticles. Also TG analysis indicated that there were two weight-loss steps for the CTAB-capped CdSe nanoparticles. It was suggested that CTAB played a significant role in protecting CdSe nanoparticles.

Elongated CdSe nanoparticles with a diameter of 3-7nm have been successfully synthesized using two surfactants of trioctylphospine (TOP) and hexadecylamine (HDA) at $160^{\circ}C$. The formation of elongated CdSe nanoparticles is possibly due to the cooperative effects from both the different binding capability of two surfactants (TOP and HDA) and intrinsically anisotropic crystal structure of the CdSe. The electron diffraction pattern of CdSe nanoparticles revealed the formation of wurzite phase. The CdSe samples showed red-shifted wavelength from 560 to 580nm with increasing the refluxing time due to the gradual growth of CdSe nanoparticles. The relatively broad absorption band can be attributed to the surface state of CdSe nanoparticles. The possible formation mechanism of elongated CdSe nanoparticles was proposed and the characteristics of CdSe have been discussed as well.

CdSe nanoparticles were prepared by chemical solution methods using CdCl₂{cdot}4H₂O (or Cd(NO₃)_ 2{cdot}4H₂O) and Na₂SeSO₃. The characteristics of CdSe nanoparticles were controlled by the react ion time, reaction temperature and reaction method as well as the surfactants. Cetyltrimethyl ammonium bromide(CTAB) was used as a capping agent to control the chemical reactions in aqueous solution. Polyvinylalcohol(PVA) was used as a templet in sono-chemical method. CdSe nanoparticles synthesized in aqueous solution showed homogeneous size distribution with relatively stable surface. CdSe nanoparticles synthesized in non-aqueous solution containing diethanolamine(DEA) showed the structure transformation from cubic to hexagonal as the reduction temperature increased from 80 to 160?C. Core shell CdSe was synthesized by sono-chemical method. Characteristics of CdSe nanoparticles were analyzed using transmission electron microscopy(TEM), x-ray photoelectron spectroscopy(XPS), x-ray diffraction(XRD), UV-Vis absorption spectra, fourier transform infrared spectroscopy(FT-IR) and photoluminescence spectra spectroscopy(PL). This paper presents simple routes to prepare CdSe nanoparticles for solar cell applications.

Line-Design에 관한 Python 프로그램

Line-Design을 작도하는 원리를 컴퓨터 프로그램으로 작성해 보았다. 컴퓨터 프로그램을 처음 익히는 초보자들도 흥미를 가지고 컴퓨터의 기본 원리를 학습할 수 있고, 각자 컴퓨터에서 Python 프로그램으로 코딩을 하다보면 컴퓨팅 사고력도 신장될 것이라 본다. 그래서 Line-Design의 Python 프로그램의 작성방법을 부족한 수준이나마 코딩의 예시를 제시하였다. 초·중등 학생들이 쉽게 학습할 수 있는 내용의 수준으로 작성하였기 때문에, 현장에서 초·중등학교 교사들이 Python 프로그램을 처음 지도할 때 보탬이 되길 희망하는 마음으로 학술지에 게재하고자 한다.

This study is aimed at re-analyzing English Quotative Inversion Constructions(QIC) from the viewpoint of parallel movement operation proposed in Chomsky(2005). To begin with, we examined and argued in favor of the v-to-T movement and the Spec-v*P subject position in QIC suggested in Collins(1997) and C & B(1997), but with several problems unsolved. In the syntactic distribution of Quote in QIC, we observed that it behaves not only as an argument but also as a non-argument like wh-phrases. We proposed, on this ground, that copies of the Quote rise to Spec-TP and Spec-CP respectively, which Chomsky(2005) called parallel A/A’-movement. In conclusion, we verified that this type of movement is the best way to account for the position of Quote in QIC in English which has been discussed for a long time.

싱가포르의 경제특구 활용을 통해 본 한국의 경제자유구역사업

김신호(Shin Ho Kim) 한국정부학회 2013 한국행정논집 Vol.25 No.4

경제자유구역사업은 외국기업단지조성사업임과 동시에 외국자본유치사업이다. 외국인이 우리나라에 자본을 투자하기 위해서는 투자기업에 최고의 가치가 마련되었는가를 전제로 한다. 이는 경제자유구역사업이 세계의 유사사업들과 경쟁을 거쳐 상대적 우위를 점유해야함을 의미한다. 외국자본유치의 국제 경쟁적 상황에도 불구하고, 우리나라는 2013년 기존의 경제자유구역에 동해안 및 충북 2개의 경제자유구역들이 추가 지정되어 발표되었다. 그렇지 않아도 우리나라 미래 산업을 위해 최적의 외국기업들을 유치하기에는 외국인 정주환경, 투자조건, 행.재정적 지원을 위한 생태계 조성이 어렵다는 비판들이 많은 상황에서 선택과 집중을 통하여 경쟁력 확보가 더 어려울 수 있다. 본 논문은 1965년 말레이시아연방에서 축출되어 인적 물적 자원의 부족과 적대적 주변국들이 생존을 위협하던 상황에서, 외국자본의 유치를 통한 수출산업육성 만이 유일한 생존의 길이었던, 싱가포르가 어떻게 세계 자본주의 경쟁시장의 냉혹함을 이겨내고 1인당 국민소득 512불에서 오늘날과 같은 5만 불이 넘는 무역과 다국적기업의 중심지가 되었는지 분석하여, 한국의 경제자유구역사업에 적용방안을 모색하고자 한다. 약소한 저개발 국가로서 세계도시로 편입될 때의 정치.경제적 위험 속에서 정책의 시행착오를 거칠 여유가 전무한 싱가포르는 국내 산업 보호망을 걷어 버리고, 다국적기업이 진출하기 가장 좋은 조건을 구축하기 위해 관세, 법인세, 각종 수입세 등의 면제를 단행하고, 외국기업을 위한 생태계를 과감히 이행하였다. 많은 국내 기업들이 해외자본의 소유가 되는 어려움과 정부조직을 투명.청렴하게 할 때의 어려움들이 있었으나, 기득권 없는 경쟁으로 세계무역도시로 거듭나게 되었다. 그들의 절박했던 생존논리와 기득권 없는 경쟁을 우리의 경제자유구역사업은 어떻게 실현할 것인가? 국내의 병원과 학교, 노조와 산업 등의 보호를 기득권으로 내세우면 과연 국제경쟁력이 있는 것일까 하는 문제와 고통스럽지만 절박할 정도로 과정에 충실할 수 있는 방안모색을 싱가포르의 상황발전과 비교하며 논의하고자 한다. Korean Free Economic Zone Business is the business to build up foreign corporation clusters and to lure foreign investment. The foreign investors search for the best spot for their future corporation to make the maximum profit. Therefore, Korean FEZs should provide best conditions for them to invest to our FEZs. It is a competition in this cold world economy market. Korean government announced the establishment of additional two more FEZs in 2013, one in East coastal region and the other in Chungbuk. There had been many critics that our FEZs are in difficulties to lure the competitive foreign investments due to the lack of ecology for the living condition, counselling, financial and administrative support. We can loose the opportunity to concentrate efforts to our FEZs because there are too many. This paper is to deal with the Singapore which was kicked out from the Malaysia Federation in 1965, was threatened from the surrounding hostile countries. Without manpower and material, Singapore choose to make export oriented economic development with the inducement of foreign investments. There was a political and economical risk that the small and poor country could be merged into the cold world-wide economy. The only way to survive is to remove their protection for their home industries, and to build the best conditions for the foreign corporations to extend their business. Singapore provided the foreign corporations the redemption of tariffs and taxes, medical and education services, land and houses with low cost. Singapore had got difficulties for their home industries to be merged into the foreign capital, for their government to be cleansed, but they removed their vested interests and become one of the best world cities. Can our FEZs make world economy competition with the protection of our hospital, school, labor union, and home industries? This paper tries to find out the way that how can our FEZs accomplish the competition without privileges, how to do our best in the process of our problem solving, comparing with the Singapore`s deployment of their situations.
