한승우,H.W. Lee,H.J. Lee,J.Y. Kim,J.H. Kim,C.S. Oh,S.H. Choa 한국물리학회 2006 Current Applied Physics Vol.6 No.1l

In the case of MEMS and NEMS, the mechanical properties of their materials are closely related to their performance and reliability.The measurement of the mechanical properties of thin lm for MEMS/NEMS is dicult because of the small sizes, forces, and displace-ments involved as well as the need for special techniques to prepare and handle the specimens.In general, micromechanical tests involve three main issues; specimen preparation, force application and measurement, and displace-ment or strain measurement. The microtensile testing system was developed. The grip ends of the specimen are glued to the grips attachedto a piezoelectrically actuated loading system. Strain is measured directly on the specimen with laser interferometry named ISDG.sputtering process, of which thickness is 1l m. For strain measurement the markers on the specimen was made by focused ion beam(FIB). Using the microtensile test, stressstrain curve, elastic modulus and ultimate tensile strength of Au thin lm was obtained.The results were compared with those of nanoindentation test.

《조선일보》와 《소년조선일보》 속 현덕의 작품을 통해서 본 식민지 헤테로토피아

한승우 한국 리터러시 학회 2021 리터러시 연구 Vol.12 No.2

While the Chosun Ilbo was a medium reflecting the colonial order as it was an adult world, the Boy Chosun Ilbo, which has the identity of a newspaper only for children, was a special space where people could enjoy a little freedom by being separated from the dominant order of the colony. In children’s newspapers, it was recognized as a modern sprout with a decent name of “child”, freed from the confines of being an inferior child produced in a colony. As such, “The Boys Chosun Ilbo” had the same function as “heterotopia”, a utopia that became a reality as well as a space of departure and escape. During the same period, Hyun-deok published novels and fairy tales in the Chosun Ilbo and The Boy Chosun Ilbo, repeatedly proposing a child protagonist named ‘Noma’. It should be noted that if the novel in The Chosun Ilbo depicts a Noma living in a ‘world of adults’ full of cold reality and absurdity, the fairy tale of the Boy Chosun Ilbo is a ‘children’s world’ with peace and coexistence. It means that he is drawing the inner normal. In the solid reality of the colonial rule, Noma is confronted and frustrated, but Noma, who is staying in heterotopia, grows safely and healthy. The space that reflected the wishes of colonial intellectuals who wished to grow in the right direction in a special space subtly hidden in reality was the Boy Chosun Ilbo, and it seems that the works of Hyeon-deok were the most visible. 《조선일보》가 어른들의 세상이면서 식민지 질서를 그대로 반영하는 매체였다면, ‘어린이만을 위한 신문’이라는 정체성을 지닌 《소년조선일보》는 식민지의 지배 질서로부터 분리되어 조그마한 자유를 누릴 수 있는 특별한 공간이었다.어린이 신문에서만큼은 피식민지에서 생산된 열등한 아동이라는 굴레에서 벗어나,‘어린이’라는 어엿한 이름의 근대적 맹아로 인정받을 수 있었다.이처럼,《소년조선일보》는 일탈과 탈출의 공간이면서 현실화된 유토피아인 ‘헤테로토피아’와 같은 기능을 지니고 있었다. 현덕은 비슷한 시기에 《조선일보》와 《소년조선일보》에 소설과 동화를 발표하면서, ‘노마’라는 이름을 가진 어린이 주인공을 반복해서 내세웠다.주목해야 할 점은 《조선일보》 속 소설이 냉철한 현실과 부조리함이 팽배한 ‘어른들의 세계’를 살아가는 노마를 그리고 있다면,《소년조선일보》의 동화에서는 평화와 공존이 있는 ‘어린이들의 세상’ 속 노마를 그리고 있다는 것이다.식민지 지배 체제가 견고한 현실 속에서 노마는부딪히고 좌절하지만,헤테로토피아에 머물고 있는 노마는 안전하고 건강하게 성장한다. 현실 안에 교묘하게 숨겨 둔 특별한 공간 안에서 바른 방향으로 성장하기를 바라는식민지 지식인들의 바람이 반영된 공간이 《소년조선일보》였으며,이를 가장 극명하게 보여준 것이 현덕의 작품들이었다고 본다.

‘배심원토론’을 활용한 민주시민 인성교육에 관한 수업방안 연구

한승우,김보영 한국 리터러시 학회 2019 리터러시 연구 Vol.10 No.1

This study sought the possibility of democratic citizenship education in universal liberal arts education. And the final goal was to develop the teaching model and to prove the effect. We introduced jury discussion as a method of democratic communication, and realized the lessons that can share and sympathize with the problems of the community. As a result, the teaching model of democratic citizenship education presented in this study and the meaning and efficacy of jury discussion are as follows. First, the combination of university liberal arts education and democratic citizenship education can be an alternative to the new personality education model. I showed the curriculum for 16 weeks, confirmed all the lessons, and confirmed the possibilities by running them. Second, we tried to differentiate from the existing university discussion methods in that we chose jury discussion as a means of communication. The structure of the jury s debate which has not been settled yet was able to present another developmental direction of the communication class. Third, we concluded that the communication 본 논문은 교양 교육 안에서 민주시민 인성 교육의 가능성을 모색해 보고, 이에따른 수업 모형을 계발하여 효능을 증명해 내는 것을 궁극적인 목표로 하였다. 민주주의에 입각한 의사소통의 방법으로 ‘배심원 토론’을 도입하였고, 공동체의 문제를 나누고 공감할 수 있는 수업을 직접 실현해 보았다. 그 결과 이 연구에서 제시한 민주시민 인성 교육의 수업 모형과 ‘배심원 토론’이 갖는 의의와 효능은 다음과같다. 첫째, 대학 교양수업과 민주시민 인성교육이 만났다는 점에서 하나의 새로운 인성 교육 모델의 대안이 될 수 있다. 16주 수업에 대한 커리큘럼을 제시하여 한 학기 수업을 전반적으로 조망할 수 있도록 하였고, 직접 실행해 보면서 그 가능성을확인해 볼 수 있었다. 둘째, 의사소통 수단으로 ‘배심원 토론’을 선택하였다는 점에서 기존의 대학 토론 방식들과 차별화를 시도하였다. 아직 자리 잡지 못한 배심원토론을 구조화하였다는 점에서 의사소통 수업의 또 다른 발전 방향을 제시할 수있었다. 셋째, 배심원 토론을 통한 의사소통 수업이 ‘사회윤리’ 측면에서 성과를 거두었다는 결과를 도출하면서, 수업의 유의미성을 실증적으로 확인하였다.

한승우,진선덕,임은홍,최성훈,이준우 한국조류학회II 2019 한국조류학회지 Vol.26 No.2

This study was conducted to investigate the effect of forest road construction on the home-range of birds in Mt. Minjuji-san. The total number of birds observed in the survey area was 879 individuals in 42 species (sum of the maximum number), and the largest number was 36 species and 335 in 3 site. The dominant species was analyzed in the top 5% in order of Emberiza elegans, Aegithalos caudatus, Paradoxornis webbianus, Parus major, Parus glandarius, Emberiza rustica. Changes in home-range by sites in Forest Road were analyzed using the coordinates of observation points for the top 5% dominant species. The home-range by MCP at Site 1 was 7.18 ha (Median). KDE 90% was 4.71ha (Median), 70%, 0.76ha (Median), KDE 50%(core area), 0.12ha (Median), respectively. The MCP of Site 2 was 7.90ha (Median), KDE 90%, 4.92ha (Median), KDE 70%, 0.8ha (Median), respectively. KDE 50%(core area) was 0.06ha (Median). MCP of Site 3 was 3.74 ha (Median). KDE 90% was 3.38ha (Median), KDE 70%, 0.45ha (Median), and KDE 50%(core area), 0.12ha (Median), respectively. KDE 90% was 3.38ha (Median), KDE 70% was 0.45ha (Median) and the core habitat KDE 50% was 0.12ha (Median). Forest road construction has brought about changes in the home-range of birds, which need to be managed because of concerns about fragmentation of habitats. 본 연구는 임도 개설이 조류의 행동권에 미치는 영향을 파악하기 위해 민주지산을 대상으로 수행하였다. 조사지역에서 관찰된 조류는 총 42종 879개체(최대 개체수의 합)이었고, Site 3구간에서 36종 335개체로 가장 많았다. 우점종은 노랑턱멧새, 오목눈이, 붉은머리오목눈이, 박새, 쇠박새, 쑥새의 순으로 상위 5% 이상 우점한 것으로 분석되었다. 임도의 Site별 행동권 변화는 상위 5% 우점종을 대상으로 관찰 지점에 대한 좌표를 활용하여 분석하였다. Site 1의 MCP에 의한 행동권은 7.18ha(Median)이었다. KDE 90%는 4.71ha(Median)이었고, 70%는 0.76ha(Median)이었으며, 핵심서식지인 KDE 50%는 0.12ha(Median)이었다. Site 2의 MCP는 7.90ha(Median)이었고, KDE 90%은 4.92ha(Median), KDE 70%은 0.88ha(Median)이었다. 핵심 서식지인 KDE 50%는 0.06ha(Median)이었다. Site 3의 MCP는 3.74ha(Median)이었다. KDE 90%는 3.38ha(Median)이었고, KDE 70%는 0.45ha(Median), 핵심 서식지인 KDE 50%는 0.12ha(Median)이었다. 임도 개설로 인해 조류의 행동권에 변화가 나타났고, 이는 서식지 단편화 등의 우려가 있어 관리가 필요하다.

大學 敎養敎育으로서의 讀書討論 授業運營 方案 硏究

한승우,손혜숙 한국어문교육연구회 2014 어문연구(語文硏究) Vol.42 No.2

The purpose of this study provide a theoretical framework for teaching reading, discussion, and real lessons here apply to step-by-step teaching and learning model adapts. For this, Kreft claimed by reading the text in the process of understanding, Waldmann the alleged ‘front stage' concept in addition, a new reading and discussion of teaching methods is proposed. In this study, the model proposed in the framework of the University of Reading in the classroom discussion ‘in the previous step (preparation phase)→1step(a subjective understanding of the text-the text to read through the task)→2step(text through the interaction between the members of the Check)→3steps(understanding of the text through discussion diversifi- cation)→4steps(text applies to external parts of the stage)’ is. As mentioned above, the University of Reading and discussion class model was proposed framework. Step 1, Read the text at the end of the preparation, the learner is the process of reading the text itself. Step two is delicate and surely it is important to analyze the text. As in step 1 to step 2, free reading must have objectivity. Step 3, the learner to experience a variety of text analysis is aimed. To do this, learners discuss the proce- dure goes through the process of thinking through the exchanges. Four step is a step of applying the text. While a variety of writing. development of their surroundings and society, to the historical part. Teaching model based on the reading and discussion, Aldous Huxley's ‘Brave New World' and Viktor E. Frankl's ‘Man's search for meaning:an introduction to logotherapy’ was to present the lesson teaching plan. Lesson Plan and thus worthy of a re-adjustment, Chungang University ‘reading and discussion' leverage in class, had the potential to sound. 본 연구는 讀書 討論 授業의 이론적 틀을 제시하고 실제 수업에 적용하여 단계별 교수․학습 모형을 實際化해 보는 것을 목적으로 한다. 이를 위해 Kreft가 주장한 읽기 텍스트의 이해 과정에 Waldmann의 ‘앞 단계’ 개념을 보강하여 새로운 독서토론 교수 방법을 제안하고자 한다. 본 연구에서 제시하는 대학 독서 토론 수업 模型의 기본 틀은 ‘앞단계(준비단계)→1단계(텍스트에 대한 주관적 이해:과제를 통한 텍스트 읽기)→2단계(구성원들 간의 상호작용을 통한 텍스트의 내용 확인)→3단계(토론을 통한 텍스트 이해의 다양화)→4단계(텍스트 외적인 부분들에 적용의 단계)’이다. 이렇게 구성된 수업 모형의 틀에 실제 텍스트(올더스 헉슬리의『멋진 신세계』와 빅터 프랭클의 『죽음의 수용소에서』)를 적용시켜 具體的인 講義 指導案을 설계하였다. 그리고 중앙대학교 ‘독서와 토론’ 수업 시간에 활용하여, 그 가능성을 타진했다.

한승우,강민주,박주호 사단법인 한국응급구조학회 2022 한국응급구조학회지 Vol.26 No.1

Purpose: This protocol aims to improve the simplicity of the existing two-person cardiopulmonary resuscitation (CPR) by focusing on chest compressions and artificial respiration, and classifying the roles within the scope that can be observed. Methods: In this study, the protocol was developed by forming an expert group consisting of a professor from the emergency and rescue department, a professor from the nursing department, and a first aid officer from the fire department. In addition, if the number of panels is 15 and the derived content validity ratio (CVR) value exceeds 0.49, a reference point that satisfies content validity at 95% reliability is presented. Results: All 11 performance items exceeded the CVR value of 0.49 to meet the reference point, and the CVR range of this protocol is 0.625 to 1.000. Conclusion: In order to improve the quality of three-person CPR, verification of simulation models and continuous protocol revision should be conducted by individuals specializing in various fields.
