오주현 아주대학교 일반대학원 2011 국내석사

최근에 개발되는 많은 신소재들 중 박막재료는 반도체나 전자 부품관련 산업에서 중요한 부분을 맡고 있으며, 박막재료에 대한 연구 및 개발이 진행됨에 따라 박막재료에 대한 열물성 측정기술도 그 필요성이 증가하고 있다. 그러나 박막재료의 열물성 측정 시 투명재료로 인한 몇 가지 문제점을 갖게 된다. 그 이유는 대부분의 박막재료는 투명재료여서 박막 표면상의 공기영역에서 충분한 온도구배를 얻을 수 없기 때문이다. 이는 검사빔의 편향을 감퇴시켜 열물성 측정 정밀도를 낮춘다. 이러한 문제를 해결하기 위하여 Collinear Deflection Method을 이용한 투명한 박막재료의 열물성 측정기법을 개발 및 적용하였다. Collinear Deflection Method는 광열편향법 중 한 방법으로서, 가열빔(pump beam)과 검사빔(probe beam)을 시편 표면에 수직으로 주사하게 된다. 그리고 검사빔은 시편 내부의 온도구배로 인한 굴절지수 변화에 의해 편향을 일으킨다. Collinear Deflection Method의 경우 검사빔이 가열빔과 평행하게 진행하고 시편을 직접 통과하기 때문에 온도변화에 따른 편향이 더욱 두드러지게 할 수 있고, 결과적으로 열물성 측정 정밀도를 크게 높일 수 있는 장점을 갖고 있다. 본 연구에서는 Collinear Deflection Method를 이용하여 박막재료에 대한 열전도계수 측정에 대한 연구를 진행하는 것을 목표로 하였다.

This study was composed of two parts. The first part was a longitudinal study. The effect of 8 years(1994-2002) of meal service was explored for the elderly regularly served lunch at a congregate meal site in terms of the changes of anthropometric data, dietary intake, dietary behavior and biochemical data. The subjects were 52 elderly (elderly with meal service(served ; 35), elderly without meal service(non-served; 17)aged >65years living in Suseo area of Seoul. The difference of the data of the served group were also compared to the those of non-served group. The second part was a cross-sectional study. The nutritional and health status were compared between the group with meal service at a congregate meal site and the group without meal service. The total subjects were 273 composed of the served group (N=137) and the non-served group (N=136) and the mean age was 76.1, 77.1, respectively. The difference of anthropometic data, nutrient intakes and biochemical data were investigated between the two groups. Study 1. Longitudinal study The effect of 8 years of meal service at a congregate meal site on the nutritional and health status of the elderly. 1. The proportion of the elderly living alone was 5.9% in 1994 and increased to 23.1% in 2002 for the served group. The proportion of elderly living with spouse was 21.6% in 1994 and decreased to 11.5% in 2002 for the non-served group. 2. Intakes of nutrients estimated with 24-hr-recall method showed tendency of increases in most of the nutrients. Significant increases were observed in the intakes of fat, calcium and riboflavin (p<0.05, respectively) for the served group after 8 years. However in the non-served group, intakes of vitamin C was the only nutrient that significantly increased after 8 years. 3. Appetite score, fruit intake score, milk intake score and the score of eating food not spicy were significantly increased(p<0.05, respectively)in the served group. In contrast, only the grain intake score was significantly increased in the non-served group after 8 years. 4. Triceps skinfold thickness (p<0.01), subscapular skinfold thickness(p<0.001), systolic blood pressure(p<0.01), diastolic blood pressure(p<0.1) were significantly dropped in the served group after 8 years of meal service. While non-served group showed significantly elevated weight (p<0.05), BMI(p<0.01), PIBW(p<0.001) and systolic blood pressure(p<0.01) after 8years. 5. The served group showed significantly elevated serum TG(p<0.05) and the non-served group HDL-cholesterol(p<0.05) after 8years. Both group were observed as having significantly increased serum total protein and albumin. Both group also showed similar pattern in terms of hematological iron status indicators. They both showed significantly increased serum iron(p<0.05) and TBC(p<0.001) and decreased MCHC(p<0.001) after 8years. 6. Increase of serum cholesterol was associated with the decreased grain intake score(p<0.05) after 8 years for all subjects. Increase of HDL-cholesterol was associated with the increase of energy (p<0.05), protein(p<0.05), calcium(p<0.05) and vitamin B1(p<0.05) intakes. Study 2. The cross-sectional study A comparison of nutritional and health status between the elderly with meal service and without 1. The served group had higher proportion of the elderly living alone and lower income. 2. The served group showed significantly higher intakes in animal protein (p<0.001), animal fat(p<0.01), animal calcium(p<0.01), animal iron(p<0.01), zinc(p<0.01), vitamin B2(p<0.001), vitamin B6(p<0.01) and cholesterol(p<0.001) compared to those of the non-served group. 3. Lunch service at the congregate meal site contributed more to the daily intake for the most nutrients in the served group compared to the non-served group. 4. There was no difference of food behavior score and food habit score related to the prevention of hyperlipidemia between the two groups. 5. The nutrition risk index score or the depression score of the served group were similar to those of the non-served group. 6. No significant difference were observed in the anthropometric data except the non-served group showed significantly higher height. 7. The served group showed significantly lower level in MCH but higher in TIBC. Other hematological variables related to lipid, protein, glucose and calcium did not show any significant difference between the two groups.

생태정치학적 측면에서 본 리더십 - 동학사상을 중심으로 -

오주현 성신여자대학교 대학원 2005 국내석사

본고는 생태 패러다임의 틀 안에서 정치의 문제를 다루는 생태정치학의 체계를 수립하고 생태정치학에 입각한 리더의 특징과 의미체계를 구축함으로써 새 시대의 요구에 부응할 수 있는 새로운 리더의 상을 정립하는 것을 목적으로 한다. 생태 패러다임은 이원론에 입각한 기존 세계관으로는 해결이 불가능했던 근대 산업문명의 여러 폐해들을 극복하고 공존의 대안적 사회를 마련하려는 모색을 시도하고 있는 총체적ㆍ통합적 패러다임이다. 정치학에서 생태 패러다임의 실현은 19C 후반 이미 동학사상을 통하여 시도된 바 있다. 존재의 본질적 문제를 다루고 생명을 중히 여기는 패러다임으로의 전환, 이론과 실천을 통합하여 현실의 장에서 그것을 구현하려 한 점은 생태정치학의 핵심인 동시에 동학사상의 목적이다. 따라서 본 논문에서는 동학사상을 생태정치학이 시도된 예로 보며, 생태정치학과 동학사상을 접목시킨 리더의 상을 조망하고자 한다. 생태정치학적 리더십은 전일성, 통합성, 평등성, 자각성, 자율성 등의 다섯 가지 기본 특징을 바탕으로 거시적으로는 우주 전체를 망라하고 미시적으로는 인간 개인의 실존 문제까지도 헤아릴 수 있는 통합적 시각을 갖출 것을 강조한다. 생태정치학적 리더의 역할은 조직원과의 관계, 세계와의 관계로 구분한다. 먼저 조직원과의 관계에 있어서 리더는 조직원이 스스로의 존재의식을 자각하고 자기 효능감을 확산시킴으로써 조직에 직접 참여할 수 있도록 유도하는 역할을 해야 한다. 세계와의 관계에 있어서는 공동체 의식을 확립함으로써 세계가 하나라는 연대의식의 확산 및 공고화를 위해 노력해야 하며 궁극적으로는 에코토피아(Ecotopia)를 구현하는데 조력해야 한다. The object of this paper shall be to construct the image of new leader who is able to meet the needs of new age and the system of eco-politics based on the eco-paradigm. The eco-paradigm is the integrative and comprehensive view of the world which be able to overcome all the problems caused by Cartesian view of the world. The realization of the paradigm had tried by "Donghak" in the latter half of the 19th century. The eco-paradigm and "Donghak" have the same view. The one is the transitional thought which treats the substance problems of all beings and respects for all life. Another is the unification of theory and practice and trying them in the field of reality. Therefore this paper is try to construct the image of new leader by the eco-paradigm and "Donghak". The eco-politician leadership has characteristic of the oneness, unification, self-consciousness and autonomy. According to these, eco-political leader plays an important role between leader and personnel, leader and world. The former role is making spontaneous participation of personnel to one's group by letting them awake their being and diffusing their self-efficancy. The latter role is helping to diffuse and consolidate the union thought means the world is the one. Ultimately the leader should help to realize the Ecotopia by realizing the very oneness of all life and letting people awake that.

오주현 수원대학교 교육대학원 2009 국내석사

This research selected possible materials and methods to be educationally used in actual lectures of Chinese language by using Chinese TV drama <The Story of a Noble Family> with basic and intermediate level learners as the subjects; moreover, appropriate professors and study systems were also planned. The organization of this research paper is as follows: In the second section, theoretical knowledge has been discussed by having two sections, which are the content of TV drama in general and the content of <The Story of a Noble Family>. First, in terms of the relationship between TV drama and Chinese language education, the concept of TV drama is explained. Then, a concise summary on the characteristics of TV drama follows. Furthermore, five educational effects by using TV drama for Chinese language education have also been stated: Motivation, cultural understanding, pronunciation and tone, vocabulary, and listening comprehension skills. After that, information related to TV drama <The Story of a Noble Family>, a brief summary, and main characters were presented. In the third section, a teaching method that can strengthen Chinese listening and speaking skills has been investigated; this was with the fact that TV drama, a set of audio-visual documents, can give the greatest effects on learners' listening and speaking sections. Before anything else, basic level and intermediate level learners were separated in categories. Then, contents and methods to educationally use for listening and speaking sections were chosen from <The Story of a Noble Family> considering each learner's ability to face a certain degree of difficulty. Finally, suitable professors and study methods were proposed. In the fourth section, educational materials were sorted from TV drama <The Story of a Noble Family> and several instructional methods were studied. First of all, educational materials were largely divided into four categories: Language, culture, history, and literature. Proper study materials for each category were selected, and professors and study methods were gathered considering interest of students and practicality. Together with this research, the expectation is to have more research in the future with respect to instructional methods using various TV dramas. This will be in order to set up a systematic way to study deliberating interest of Chinese language learners and practicality.

자유학기제에서의 현악 합주 수업 지도방안 연구 : ASSURE 모형을 기반으로

오주현 연세대학교 교육대학원 2022 국내석사

The purpose of this thesis is to develop an instruction plan for string ensemble classes in the free semester system using the ASSURE model. In this study, the concept, purpose, and curriculum of the free semester system were reviewed through various studies to better understand the free semester system. In addition, the concept and step-by-step characteristics of the ASSURE model that was to be used for the development of string ensemble instruction were identified; based on this, string ensemble instruction plans were devised for first-year middle school students lasting for 17 sessions in total. Classes are held for 90 minutes once a week by applying the block time system of the free semester system, with the same learning goal for two sessions each, and for the last 17th session, a volunteer concert is to be held. Through this class, students can learn the musical concept of a musical piece and learn in depth musical concepts that they have acquired by playing an instrument. The materials of the class are “Twinkle Twinkle Little Star”, Bach's “Minuet No. 3”, and Mozart's “Serenade.” In order to incite students' interest, the teaching method requires students to systematically practice songs starting from easier songs, gradually increasing the difficulty level. In Lessons 1-4, after understanding the atmosphere, composition, and tempo of a musical piece through “Twinkle Twinkle Little Star”, students will learn how to apply the concepts learned in those lessons by actually playing an instrument. Lessons 5-8 aim to understand not only the composition and tempo of Bach's “Minuet No. 3”, but also performance techniques. In addition, students will apply what they have learned and understood into practice by playing an instrument. Lessons 9-14 study Mozart's “Serenade.” Students will practice playing in an ensemble based on understanding the background of the music and the sonata form through its structure, rests, and musical symbols. In the 15th and 16th sessions, students will practice the three pieces of music that they have learned so far, and prepare for the volunteer service concert to be held in the final session. In the 17th and final session, there will be a volunteer service performance. Through this, students will have an opportunity to directly experience the meaning and value of volunteering through music. The significance of this study is as follows. Through the free semester system, there is sufficient time to experience the string ensemble, which was previously difficult to enact in a class setting due to time constraints. In addition, if the class is designed through applying the 6 steps of the ASSURE model, a clearer and more systematic class design is possible. Finally, through playing in a string ensemble, students are expected to grow a more ethical attitude which will last into their adulthood by cultivating not only the ability to hear and appreciate music, but also cooperation, consideration, and responsibility. It is hoped that this study can contribute to the educational field as a guidance method that promotes in-depth understanding and enhances musical sensibility by directly engaging the students as they will gain a better comprehension of musical concepts via playing them with their instruments. 본 논문은 ASSURE 모형을 활용하여 자유학기제에서의 현악 합주 수업 지도안을 개발하는 데 목적이 있다. 본 연구에서는 자유학기제에 대한 이해를 위하여 자유학기제의 개념과 목적, 교육과정을 여러 문헌을 통해 고찰하였다. 그리고 현악 합주 지도안 개발을 위해 활용할 ASSURE 모형의 개념과 단계별 특징을 파악하고 이를 바탕으로 중학교 1학년 대상의 총 17차시의 현악 합주 수업 지도안을 고안하였다. 수업은 자유학기제의 블록타임제를 적용하여 주 1회 90분씩 진행하고, 2차시씩 같은 학습목표를 가지고 활동을 하며 마지막 17차시는 봉사 연주회를 진행한다. 본 수업을 통해서 학생들은 악곡에 대한 음악적 개념을 학습하고, 악기 연주를 통해 배운 음악적 개념들을 깊이 있게 학습할 수 있다. 수업의 제재곡들은 <작은 별>, 바흐의 <미뉴에트 3번>, 모차르트의 <소야곡>이다. 학생들의 흥미를 돋우기 위해 쉬운 곡부터 어려운 난이도의 곡들을 체계적으로 연습한다. 1-4차시에는 작은 별 악곡을 통해 악곡의 분위기, 조성, 박자에 대한 이해를 한 후, 악기 연주를 통해 배운 개념들을 적용해본다. 5-8차시는 바흐의 미뉴에트 3번 악곡에 대한 조성과 박자뿐만 아니라 연주 주법에 대한 이해를 목표로 한다. 또한 이해한 내용을 악기 연주를 통해서 실제로 적용해본다. 9-14차시는 모차르트의 소야곡을 학습한다. 악곡에 대한 배경과 소나타 형식의 구조, 쉼표, 악상기호에 대한 이해를 바탕으로 합주 연습을 한다. 15-16차시는 그동안 배웠던 세 가지의 악곡을 전체적으로 연습하며 다음시간에 있을 봉사연주회를 준비한다. 17차시는 봉사 연주를 진행한다. 이를 통해 음악을 통한 봉사의 의미와 가치를 직접 체험해보는 기회를 가질 수 있도록 계획하였다. 본 연구의 의의는 다음과 같다. 자유학기제의 활동을 통해서 단 시간으로 학습하기 어려웠던 현악 합주 경험을 할 수 있는 시간적 여유가 생긴다. 또한 ASSURE 모형의 6단계를 적용하여 수업을 설계한다면 보다 명확하고 체계적인 수업 설계가 가능하다. 마지막으로 현악 합주를 통해서 소리를 듣는 능력뿐만 아니라 협동심, 배려심, 책임감을 함양하여 바른 인성을 가진 성인으로 성장하기를 기대한다. 본 연구는 음악적 개념을 악기로 직접 연주하며 깊이 있는 이해를 도모하고 음악적 감수성을 증진시키는 지도방안으로서 실제 교육현장에 기여할 수 있기를 바란다.

오주현 공주대학교 대학원 2010 국내석사

해상지자기 관측자료로부터 연구지역의 지자기 특성 및 자기이상을 분석하였으며, 선행연구들과 비교하여 주변해역에 대한 전체적인 지질특성 및 구조를 확인하였다. 지자기 특성을 통해서 연구지역의 지질구조 해석을 하기 위해 먼저, 해상과 육상의 고정점에서 지구자기장을 측정한 Data를 정리했다. 그리고 지하 지질에 의해 발생되는 지자기 이상을 얻기 위해 일변화보정, IGRF보정, 잡음제거, 교차점 보정 등의 자료처리과정을 거쳤으며, spectrum 분석을 통해 연구지역 밀도불연속면의 심도를 파악하여 음향기반암(Acoustic basement)의 심도모델을 만들었다. 정규보정 및 자료처리과정을 수행한 결과 조사해역의 전자력분포는 49000~51600nT 로 황해 해역에서의 정상 전자력세기 분포에 속하는 것으로 나타났다. 등자력선의 분포는, 북동-남서방향으로 분포하고 있는 것으로 나타났으며, 북서쪽으로 갈수록 전자력치가 증가하는 경향을 보였다. 연구지역의 자기이상은 -600~1200nT 사이의 분포를 보였다. 연구해역의 자기 이상 분포는 대체적으로 해저면 하부에 발달되어있는 제3기 퇴적분지와 백악기 기반암의 분포에 따른 영향을 나타내고 있는 것으로 판단된다. 연구지역의 음향기반암 심도 모델링 결과 최저 0.42km, 최고 8.14km의 심도를 보여주었으며, 평균 깊이는 3.66km로, 탄성파 및 기타 물리탐사결과로 보고된 황해의 평균 기반암심도를 보여주었다. 북북동-남남서 방향의 황해도-서해 구조선을 따라 나타나는 이상대와 흑산분지와 군산분지 사이에 발달된 넓은 띠모양의 양의 이상대는 퇴적분지 내에서 융기된 기반암의 존재를 시사한다. 백악기 기반암 지역은 상대적으로 높은 자력이상을 나타내고 제 3기 퇴적분는 낮은 자력이상을 나타내고 있다. 연구지역 남서부와 북동부에 나타난 고자력이상대는 화성관입암체 혹은 분출암의 영향으로 사료된다. This study analyzed characteristics of terrestrial magnetism and geomagnetic anomaly in the study area from the observed data about ocean terrestrial magnetism, and it examined total geological features and structures in surrounding seas by comparing with precedent studies. To analyze the geological structure of the study area through characteristics of terrestrial magnetism, the study firstly arranged measurement data of earth magnetic field on the fixed point of a sea and a land. It conducted data processing such as diurnal correction, IGRF, and removal of noise, and cross-over correction, and made an depth model of acoustic basement by grasping the depth of density discontinuous layers in the study area through spectrum analysis. According to the regular correction and data processing, the distribution of electromagnetic force in the study sea was 49000~51600nT which is within the distribution of normal electromagnetic force in the Yellow Sea. The isodynamic line is distributed to the northeast and the southwest. Shifting to the southwest, electromagnetic force is increasing. The geomagnetic anomaly in the study area showed the distribution of -600~1200nT. The distribution of geomagnetic anomaly in the study area is shown to be affected by the distribution of in the tertiary marine basin and the Cretaceous basement that is generally developed in the lower part of the sea floor. The result of a depth modeling of acoustic basement in the study shows 0.42km of the lowest depth and 8.14km of the deepest depth. As a average 3.66km depth, the average depth of basement in the Yellow Sea that is reported as analysis of the elastic wave and physical prospecting. An anomaly shown in the tectonic line of the north-northeast and the south-southwest Hwanghae-the western sea and a wide band-shape anomaly developed in Huksan basin and Gunsan basin imply existence of basement uplifted in sedimentary basin. The basement area in the Cretaceous shows relatively high magnetism while the tertiary marine basin shows low magnetism. The anomaly with high magnetism shown in the southwestern and northeastern areas seems to be affected by igneous intrusion or igneous extrusive rocks.
