조서현,이성갑,여진호 한양대학교 세라믹연구소 2016 Journal of Ceramic Processing Research Vol.17 No.4

In this study, we fabricated the electrolyte-insulator-metal sensor on the base of Si3N4 film-coated AAO template with variationof the heat treatment time. The structural and electrochemical properties of AAO sensor were investigated for applicationsin chemical sensors. Si3N4 layer was uniformly coated with the thickness of about 10 nm. Alumina layer, heat-treated for 10h, crystallized from the amorphous phase to crystalline phase of γ-Al2O3, and the spacing of lattice plane of the oxide layerwas about 2.638 Å. The AAO sensor heat-treated for 10 h showed the good normalized C-V properties, and the set values ofthe capacitance and the pH sensitivity were −0.3 V and 54.1 mV/pH, respectively

반편견 교육에 대한 유치원 교사의 인식과 실태조사

조서현 한국교원대학교 유아교육연구소 2006 한국유아교육연구 Vol.8 No.-

The present study was to investigate how kindergarten teachers' awareness and the actual condition of anti-bias education differ according to their educational level, career experience, and kindergarten type. Findings of this study were as follows: First, kindergarten teachers' overall awareness of anti-bias education showed that most teachers were "a little" interested in anti-bias education and had "moderate" knowledges related to anti-bias education. Second, regarding the actual condition of anti-bias education, most teachers were "not so much satisfied" with current anti-bias education. The most highly responded category about the number of giving anti-bias education was "when necessary." Its teaching method was found to be "giving anti-bias education wh en necessary rather than giving intensive education within one unit." The most highly responded category about the parent educating program for anti-bias education was "using messages." The Parent educating method using a udio-visual education had significant differences according to educational level, career experience, and kindergarten type. "Shortage of in-service training" was perceived as the biggest problem of anti -bias education and "providing teaching materials for anti-bias education" was perceived to activate anti-bias education. Teachers who had higher educational level and career experience and worked for public kindergartens more highly required development of the teaching material appropriate for our situation and the in-service training program for anti-bias education. 본 연구의 목적은 반편견 교육에 대한 유치원 교사의 인식과 실태가 학력, 경력, 기관유형에 따라 어떠한 차이가 있는지를 알아보는 것으로써, 인식을 전체적으로 알아본 결과는 첫째, 유치원 교사의 반편견 교육에 대한 관심 정도와 관련 지식은 학력과 경력이 높을수록 높은 것으로 나타났다. 반편견 교육에 관한 현장의 실태를 알아본 결과 현재 실시하고 있는 교사들은 그다지 만족하고 있지 않은 것으로 나타났으며, 실시정도와 실시 방법 면에서는 ‘필요시마다 실시한다’에 가장 높은 반응을 보였다. 반편견 교육에 대한 교수 방법을 알아본 결과 이야기 나누기 시간과 대․소집단 활동에서 가장 많이 실시하고 있다고 응답하였고, 반편견 교육 활동 시 참고 자료는 교육부 지도 자료집을 가장 많이 참고하고 있다고 나타났고, 교수 매체는 ‘시각매체(도서자료 등)’에서 학력이 높을수록 높게 활용되고 있는 것으로 분석되었다. 반편견 교육의 교사 연수에 관한 참여 정도는 전체적으로 2년에 1회 정도에 가장 높은 반응을 보였으며 학력이 높고 경력이 높은 교사일수록 반편견 교육의 연수 참여 정도가 높은 것으로 나타났다. 반편견 교육을 위한 부모교육 방법으로는 가정 통신문을 활용하고 있다는 것에 가장 높은 반응이 나타났고, 반편견 교육의 문제점으로 워크숍 또는 연수 기회의 부족이 가장 큰 원인이 된다고 분석되었고, 우리나라 상황에 맞는 반편견 교육자료 개발과 반편견 교육 교사 연수 프로그램 계발이 시급히 요구됨을 알 수 있었다.

조서현,정혜린,이성갑 한양대학교 세라믹연구소 2016 Journal of Ceramic Processing Research Vol.17 No.5

We fabricated the Si3N4 film-coated anodic aluminum oxide (AAO) template for chemical sensors. The average depth anddiameter of pores were increased with increasing the second anodizing time and pore widening time, respectively. The averagedepth of pores of AAO template with the second anodizing time of 10 min was about 1.49 µm. The porous AAO sensor withthe second anodizing time of 10 min and pore widening time of 15 min showed the highest capacitance of 142.92 nF. Thecapacitance increased in the pore widening time from 0 min to 10 min and gradually saturated at 15 min or more. The porousAAO sensor with the second anodizing time of 10 min and pore widening time of 10 min showed the good normalized C-Vproperties, and the pH sensitivity and the set values of the capacitance, working point, of these devices were 0.63 V, 0.27 V,53.6 mV/pH and 48.2 mV/pH, respectively

조서현,이성갑,여진호 한양대학교 세라믹연구소 2015 Journal of Ceramic Processing Research Vol.16 No.1

We fabricated the electrolyte-insulator-metal (EIM) sensor on the base of Si3N4 film-coated AAO (anodic aluminum oxide) template for chemical sensors. The average pore size and the thickness of the AAO template were approximately 160 nm and 168 nm, respectively. The outer oxide layer thickness of the bottom part, the interface between the Al2O3 pore and the Al metal substrate, was thicker than that of the side part, and the thickness of inner oxide layer and outer oxide layer of the bottom part were about 24 nm and 30 nm, respectively. The spacing of lattice plane of the oxide layer was about 2.387 Å. The average pH sensitivity was 51.6 mV/pH.

조서현,김대영,정광호,이성갑,김영곤 한양대학교 세라믹연구소 2012 Journal of Ceramic Processing Research Vol.13 No.1

PZT/BFO multilayer thin films were fabricated by the spin-coating method on Pt(200 nm)/Ti(10 nm)/SiO2(100 nm)/p-Si(100)substrates using BiFeO3 and Pb(Zr0.52Ti0.48)O3 metal alkoxide solutions. All PZT/BFO multilayer thin films show the typical XRD pattern of a polycrystalline rhombohedral structure and a uniform and void free grain microstructure. The thickness of the BFO and PZT film by one-cycle of drying/sintering was approximately 40 nm and all films consist of fine grains with a relatively flat surface morphology. PZT/Pt and Pt/Ti interfaces became more and more rough interfacial layers with an increase in the number of coatings because the diffusion of Pb from PZT film into the Pt bottom electrode and the diffusion of Ti was more advanced with an increase in the number of annealing process. All the films showed hysteresis loops with high rectangularity. The remanent polarizations of PZT/BFO and PZT/BFO/PZT multilayer thin films are 47.85 C/cm2 and 39.97 C/cm2, respectively.

딥 러닝을 활용한 인공지능의 예술표현 사례 연구

조서현,이필하 사단법인 한국조형디자인협회 2019 조형디자인연구 Vol.22 No.1

This study examined artistic expression by artificial intelligence(AI), which is one of the recently emerging topics in the human industries. By analyzing cases of artistic expression by AI up to the present, this study aims to ascertain the new possibilities and limitations presented by AI with regard to the artistic acceptance of science and technology. It also intends to provide the foundations for the future development of AI-based art. For this purpose, we first presented the concept of deep learning in addition to the direction and characteristics of how art is evolving in the age of AI. Based on this, we analyzed cases of AI-based artistic expression such as Deep Dream, The Next Rembrandt, and Aaron, making distinctions between the aspects of direct and indirect expression and based on the criteria of creativity and autonomy of action. This study’s case analysis revealed that machine learning systems built upon ANN, which mimics human neural activity, were able to imitate the information processing methods of the human brain—i.e., discovering patterns within the myriad data and identifying objects—such that they could learn diverse images from the 15th to the 20th century. We also found that they could use the vast accumulated data to freely draw pictures as they intended. Furthermore, we confirmed the need to study how the highly superior learning speed of AI, and the development thereof, would affect the arts in general. This study’s significance lies in that, by examining artistic expression through science and technology, it explores the changes in how the meaning of art—which is a relative attribute that changes with the times—is realized and expressed. Therefore, based on this research, we expect to expand the artistic expression of artificial intelligence that thought about the relation between art and artificial intelligence in various angles. 본 논문은 최근 떠오르고 있는 인류 산업의 과제인 인공지능의 예술표현에 대해 연구하였다. 지금까지의 인공지능 예술표현 사례 분석을 통해 앞으로 과학기술의 예술적 수용에 있어 인공지능이 지니는 새로운 가능성과 한계점을 파악하여 인공지능을 활용한 예술이 발전할 수 있는 기반을 마련하는 데 그 목적이 있다. 이를 위해 딥 러닝의 개념과 인공지능 시대에서 예술의 전개 방향과 특징을 파악하고, 창의성과 행위의 주체성을 기준으로 인공지능의 예술표현 사례를 간접적 표현 측면과 직접적 표현 측면으로 나누어 Deep Dream, The Next Rembrandt, Aaron 등을 분석하였다. 사례 분석을 통해 인간의 신경활동을 본떠 만든 인공신경회로망을 기반으로 구축한 기계학습, 즉 인간의 두뇌가 수많은 데이터 속에서 패턴을 발견한 뒤 사물을 구분하는 정보처리 방식을 모방한 인공지능은 스스로 15세기부터 20세기에 이르기까지 다양한 이미지를 학습할 수 있으며, 축척된 방대한 데이터를 통해 원하는 형태의 그림을 자유롭게 그릴 수 있다는 사실을 알 수 있었다. 또한 인간과 비교할 수 없는 인공지능의 습득 속도에 따른 발달이 예술분야 전반에 미칠 영향으로 연구 필요성을 확인하였다. 본 연구를 통해 과학기술을 활용하여 예술을 표현하는 것은 변화하는 시대 속에서 다르게 요구되는 상대적 속성인 예술의 의미를 구현하는 방식의 변화이자 표현양상임을 알 수 있었다. 따라서 본 연구를 기반으로 다각도에서 예술과 인공지능의 관계에 대해 생각한 인공지능의 예술표현 확장을 기대한다.

『화엄경』 보살도가 가진 인성교육에서의 의의

조서현 동양사회사상학회 2017 사회사상과 문화 Vol.20 No.4

Buddhism can provide some workable solutions to the CEPA’s stated goal of “an education aiming for cultivating humane character and capacity.” In particular, the list of core values specified by the CEPA corresponds to practice techniques stipulated by the bodhisattva path presented in the Avataṃsaka Sutra, which teaches how to practice the values desperately needed in our time. The bodhisattva path of the Avataṃsaka Sutra provides a manual for putting the values of character education into action, and concrete guidelines for specific conduct. I believe the bodhisattva path, as presented in the Avataṃsaka Sutra, has great potential to provide a refreshing paradigm in developing a strategy for the implementation of character education. I want to limit the boundary of the “core values” and “core capacities” presented by the CEPA within that of the values for character education that can be implemented in the Korean educational system based on the bodhisattva practice techniques presented in the Avataṃsaka Sutra. These values can be applied to teachers and leaders in charge of character education, as well as to students, and I expect a variety of departmentalized programs be developed for this purpose. Because the bodhisattva path stipulates concrete methods for how to put values into action, I want to shed new light on it as a source of values needed for human character development in our time. 불교는 2600여년의 오랜 세월 속에서 다양한 수행법이 전승·변용되어 왔다. 그래서 불교는 ‘인간다운 성품과 역량을 기르는 것을 목적’으로 하는 인성교육에 수많은 대안을 제시할 수 있다. 특히 “인성교육진흥법”에서 제시한 핵심 가치·덕목의 내용은 『화엄경』 보살도에 풍부하게 제시되어 있다. 『화엄경』의 보살도는 인성교육의 실천덕목의 안내서이며, 구체적 행동 지침서이다. 보살의 서원(誓願)은 일으키는 마음이며 인성교육의 인성을 함양시키는 마음가짐과 나아가야 할 바를 자세히 알려주고 있기 때문이다. 『화엄경』의 보살도는 인성교육에 새로운 패러다임으로 기여할 것으로 기대된다. 『화엄경』 보살도는 “인성교육진흥법”에서 제시하고 있는 ‘핵심 가치·덕목’과 ‘핵심역량’을 교육현장에서 실행할 수 있는 인성교육의 또 다른 길이 될 것이다. 보살의 수행의 바탕엔 이타심과 자비심이 있다. 이타심과 자비심은 사회공동체를 위한 회향의 마음이며, 인성 가치 덕목인 이해와 배려, 공감과 소통의 버팀목이 되는 마음가짐이다. 또한 학생뿐 아니라 성인, 학생, 인성교육을 담당하는 교사와 지도자의 덕목으로 더 다양하고 세분화 된 실천 프로그램이 계발될 수 있을 것이다. 『화엄경』 보살도를 통해 이 시대에 우리들의 인성 함양을 위한 가치덕목을 재조명하고자 한다.

The purpose of this study is to examine the moderating effects of supervisory relationship between play therapist's developmental level and countertransference management ability. The subjects of this study were 165 play therapists with supervision experience. The results of this study can be summarized as follows. First, as a result of a correlation analysis on the relationship between play therapist's developmental level, supervisory relationship (safe base, reflective education, structure) and countertransference management ability all showed a significant and positive correlation to each other. Second, as a result of hierarchical multiple regression analysis conducted to examine the moderating effects of supervisory relationship (safe base, reflective education, structure) between play therapist's developmental level and countertransference management ability, safe base, reflective education, structure showed significant moderating effects on the relationship between play therapist's developmental level and countertransference management ability. In this study, it is meaningful to expand the study on the play therapist's ability to manage countertransference by examining the moderating effect of the supervisory relationship in the relationship between play therapist's developmental level and countertransference management ability.
