사회과 법교육에서 인적자원 활용의 논리 : 미국 법교육을 중심으로
박용조(Park Yongjo) 미국헌법학회 2011 美國憲法硏究 Vol.22 No.3
The purpose of this study is to find the logics of using resource people in law-related education(LRE). In order to achieve the purpose of this study, I examined aspects of using resource people in it. Finally, I found the logics of using resource people in LRE. The major results from this study are as follows. First, the use of resource people is a way to support content expertise in LRE. Second, the use of resource people is a way to disseminate LRE throughout the United States. Third, the use of resource people is a way to integrate contents into the instruction for effective LRE. Fourth, the use of resource people is a way to implement LRE for delinquency prevention. In using resource people in LRE, above all, we should be based on the logic to integrate contents and methods into the instruction for effective LRE. 본 연구는 사회과 법교육에서 인적자원의 활용이 법교육에 주요한 특징으로 자리 잡게 된 까닭을 이해하는 것을 목적으로 한다. 이를 위해 한국 법교육의 모델이 되고 있는 미국 법교육의 변천과정을 검토하여 법교육에서의 인적자원의 활용 논리를 추출하고자 했으며, 1930년대부터 오늘날에 이르기까지 국가 수준의 법교육에 영향을 미친 프로그램을 대상으로 살펴보았다. 본 연구의 결과는 다음과 같다. 사회과 법교육에서 인적자원을 활용하는 것은, 첫째, 법 내용의 전문성을 교육적으로 완화시키기 위해서였다. 법 내용의 어려움과 전문성을 극복하기 위한 방안으로 법 관련 인적자원을 활용하였다. 둘째, 법교육의 확산을 위해서였다. 법교육을 확산하는 과정에서 조직화된 법조 단체의 인적자원을 활용하게 되었다. 셋째, 법교육의 내용과 방법을 효율적으로 통합하기 위해서였다. 법교육의 방법 면에서 인적자원의 활용이 효율적인 기법이었다. 넷째, 비행 예방 교육의 적절한 수단이었기 때문이다. 비행 예방 교육에서 인적자원 활용의 효과가 검증되어 법교육에서 항상 준비해야 하는 활동이었다. 이상과 같은 연구 결과가 시사하는 바는, 사회과 법교육에서 인적자원을 활용하는 경우, 내용과 방법의 통합이라는 교육의 논리에 기초하여야 하며, 이를 바탕으로 다양한 논리를 균형 있게 받아들여야 한다는 점이다.

<P>Solid-phase epitaxy (SPE), a solid-state phase transition of materials from an amorphous to a crystalline phase, is a convenient crystal growing technique. In particular, SPE can be used to grow α-Al<SUB>2</SUB>O<SUB>3</SUB> epitaxially with a novel structure that provides an effective substrate for improved performance of light-emitting diodes (LEDs). However, the inevitable two-step phase transformation through the γ-Al<SUB>2</SUB>O<SUB>3</SUB> phase hinders the expected improved crystallinity of α-Al<SUB>2</SUB>O<SUB>3</SUB>, and thereby further enhancement of LED performance. Herein, we provide a fundamental understanding of the SPE growth mechanism from amorphous to metastable γ-Al<SUB>2</SUB>O<SUB>3</SUB> using transmission electron microscopy (TEM) and density functional theory (DFT) calculations. The nanobeam precession electron diffraction technique enabled clear visualization of the double-positioning domain distribution in the SPE γ-Al<SUB>2</SUB>O<SUB>3</SUB> film and emphasized the need for careful selection of the viewing directions for any investigation of double-positioning domains. Void and stacking fault defects further investigated by high-resolution scanning TEM (STEM) analyses revealed how double-positioning domains and other SPE growth behaviors directly influence the crystallinity of SPE films. Additionally, DFT calculations revealed the origins of SPE growth behavior. The double-positioning γ-Al<SUB>2</SUB>O<SUB>3</SUB> domains randomly nucleate from the α-Al<SUB>2</SUB>O<SUB>3</SUB> substrate regardless of the α-Al<SUB>2</SUB>O<SUB>3</SUB> termination layer, but the large energy requirement for reversal of the γ-Al<SUB>2</SUB>O<SUB>3</SUB> stacking sequence prevents it from switching the domain type during the crystal growth. We expect that this study will be useful to improve the crystallinity of SPE γ- and α-Al<SUB>2</SUB>O<SUB>3</SUB> films.</P> [FIG OMISSION]</BR>

In order to develop transparent contacts for InGaN-based light emitting diodes (LEDs), we investigated the eects of the ambient gas (N2 or O2) during annealing of Ni/Au contacts on the contact resistivity, the light transmittance, and the performance of LEDs. The minimum contact resistivity of the Ni/Au contacts annealed in O2 was 8.9 10က4 cm2, which was much lower than that of the contacts annealed in a N2 ambient (6.1 10က3 cm2). The lower contact resistivity of the oxidized Ni/Au contacts was explained by both the formation of NiO and an enhanced outdiusion of H during annealing in the O2 ambient. The oxidized Ni/Au contacts produced a high light transmittance of 90 % at 470 nm. The LEDs with the oxidized Ni/Au contacts showed a two times higher output power and a lower operating voltage at 20 mA compared with those for contacts annealed in a N2 ambient.

<P><B>Abstract</B></P> <P>Breast cancer is the most frequently diagnosed life-threatening cancer in women. Triple-negative breast cancer (TNBC) has an aggressive clinical behavior, but the treatment of TNBC remains challenging. MicroRNAs (miRNAs) have emerged as a potential target for the diagnosis, therapy and prognosis of breast cancer. However, the precise role of miRNAs and their targets in breast cancer remain to be elucidated. Here we show that miR-218 is downregulated and miR-129 is upregulated in TNBC samples and their expressions confer prognosis to patients. Gain-of-function and loss-of-function analysis reveals that miR-218 has a tumor suppressive activity, while miR-129 acts as an oncomir in breast cancer. Notably, miR-218 and miR-129 directly target Lamin B1 and Lamin A, respectively, which are also found to be deregulated in human breast tumors. Finally, we demonstrate Lamins as the major factors in reliable miR-218 and miR-129 functions for breast cancer progression. Our findings uncover a new miRNA-mediated regulatory network for different Lamins and provide a potential therapeutic target for breast cancer.</P> <P><B>Highlights</B></P> <P> <UL> <LI> miR-218 is downregulated and miR-129 is upregulated in breast cancer. </LI> <LI> miR-218 inhibits and miR-129 promotes breast cancer proliferation and migration. </LI> <LI> Lamins are identified as a novel target of miR-218 and miR-129. </LI> <LI> miR-218 and miR-129 play their biological functions by Lamins in breast cancer. </LI> </UL> </P>
Growth of High Quality Ge Layer on Silica Nano-Spheres Integrated Ge/Si Template Using UHV-CVD
Shin, Keun Wook,Park, Sung Hyun,Park, Yongjo,Yoon, Euijoon The Electrochemical Society 2015 ECS journal of solid state science and technology Vol.4 No.3
<P>We have investigated the growth of high quality Ge layer on Si substrate using silica nano-spheres (NSs), which behaved as masks to directly block threading dislocations. Two-step growth after the silica NS incorporation into the surface led to a coalesced Ge layer with low threading dislocation density (TDD). TDD in the resultant Ge layer was reduced from 6.4 × 10<SUP>8</SUP> to 6.9 × 10<SUP>7</SUP> cm<SUP>−2</SUP>, and decreased further to 1.4 × 10<SUP>7</SUP> cm<SUP>−2</SUP> by post annealing. In addition to the TDD reduction, we speculated that the suppression of {111} facet during the growth restricted significantly the generation of planar defects.</P>

<P>The junction temperature rise of light emitting diodes due to self-heating effects during operation of the LED is measured using the electro-luminescence of the band-to-band recombination. This method is useful for the junction temperature monitoring of small geometry devices, indirectly. The junction temperature measured in InGaN/GaN multi-quantum well LEDs with 1 mm<SUP>2</SUP> device size rises to 180 °C when the input current is 380 mA. The relationship between the junction temperature and the LED efficiency is clarified with experimental results. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)</P>
