한현서 동아대학교 대학원 2022 국내석사

동물은 인간과 다양한 관계를 형성하고 있다. 가족 구성원의 하나로 동거하는 반려동물부터 가축, 야생동물, 그리고 우리가 먹거나, 치장하거나, 연구하는데 사용하는 동물들까지 그 종류는 다양하다. 우리는 동물들의 생명을 소비해왔다. 생명 그 자체를 존중하지 아니하고 동물을 마치 종이와 같은 소비재인양 쉽게 사고 팔며 죽이기까지 해왔다. 동물들은 왜 그 자체의 생명으로써 대우받지 못하고 사람들로 하여금 이용되기만 했을까. 그들 또한 그들의 소리로 끊임없이 그만해달라며 소리쳤을 것인데, 그 소리에 귀기울여주지 못하고 그저 그들의 희생으로 발전된 과학을 누리는 삶에 만족했던 자신이 부끄러웠다. 본 연구는 동물 상업주의가 팽배한 사회상을 꼬집는 본인의 작품들을 프로젝트 형식으로 담아내었다. 동물 생명의 수요와 공급 패턴에 대하여 분석하고, 그로 하여금 불거진 동물 생명경시풍조를 다양한 사례를 들어가며 비판했다. 본인 뿐만 아니라 동물 상업주의가 만연하게 된 자본주의 사회 자체를 지양, 지향하는 많은 현대미술, 현대도자 작가들에 대해서도 분석하며 본 연구를 통해 전달하고자하는 바를 명확히 하였다. <펫샵>, <동물원>, <모피,가죽>, <동물실험>의 4가지 주제의 프로젝트를 진행했다. 우리 주변에서 가장 쉽게 맞닥뜨릴 수 있는 주제를 통해 다양한 사례 속에서 동물들이 느낄 감정과 공포를 작품으로 오롯이 표현하는 데에 주안점을 두고 진행했다. 그들의 표정과 상황을 낱낱이 작품으로 표현하고 인간과 동물의 역할을 뒤바꿔 표현하며 관람자들에게 스스로 되돌아볼 수 있는 시간을 만들고자 하였다. 작품만을 그대로 표현해내기보다 왜 이런 작품을 구성하였는지에 대한 스토리와 구체적인 흐름을 표현해내기 위해 노력했다. 동물과의 가까운 관계부터 내 주변의 일이라고는 생각지 않았던 관계들까지 다루어내었기에 본 연구를 통하여 많은 사람들이 동물 생명경시풍조의 문제점들을 인식하고 함께 고쳐나가는데에 동참하기를 바란다.

한현서 국민대학교 자동차공학전문대학원 2020 국내석사

최근 위험상황에서 운전자의 인지반응 특성을 이용한 고의 교통사고가 증가하여 점차 지능화, 조직화 되는 경향을 보이며, 선량한 운전자들이 받는 경제적 피해부담이 증가하고 있다. 이는 경제사회적으로 막대한 손실을 초래할 뿐만 아니라 장기적 관점에서 사회불안요소로 작용할 수 있는 상황이다. 국내에는 고의 교통사고를 판별할 수 있는 체계적인 감정기법이 부재하며 운전자의 고의성 여부를 판단할 수 있는 “위험 인지반응시간”데이터베이스 등이 구축되어 있지 않다. 국내 운전자의 인지반응시간 및 행동특성에 관한 연구는 주로 도로설계기준의 확인 위주로 수행되어 교통사고 감정에 활용하기에 적절하지 않다. 따라서 국내 교통 환경 및 내국인의 특성을 반영한 운전자의 행동특성 연구가 필요한 실정이다. 본 논문에서는 도심로 내에서 발생하는 4가지 교통사고 위험상황(맞은편 차량의 중앙선 침범, 끼어들기, 보행자 무단횡단, 교차로 위험상황)을 시뮬레이터에 구현한 뒤 20대, 30대, 40대 실험참가자를 대상으로 위험상황 발생 시 대처방법 및 인지반응시간 등을 확인하였고, 이를 연령대, 성별, 위험상황, 속도별로 통계적으로 유의미한 차이가 있는지에 대해 분석하고 제시하였다. Recently, the number of intentional traffic accidents using driver cognitive response characteristics has increased, showing a tendency to become intelligent and organized gradually, and the burden of economic damage suffered by good drivers has increased. This is not only an economic and social loss, but also a situation that can serve as a social anxiety In Korea, there are no systematic appraisal techniques for determining intentional traffic accidents, and there are no "Perception-response time" databases that can determine drivers' intent. Research on the cognitive reaction time and behavioral characteristics of domestic drivers is mainly conducted to verify road design standards and is not suitable for use in traffic accident feelings. Therefore, it is necessary to study the behavioural characteristics of drivers that reflect the domestic traffic environment and characteristics of locals. In this paper, we implemented four traffic accident hazard situations (intervention of the centerline of the right vehicle, interception, pedestrian jaywalking, crossroad hazard) in the simulator and identified response methods and cognitive response times in case of a hazard, and analyzed whether they differed statistically by age group, gender, risk situation and speed.

한현 한밭대학교 대학원 2012 국내석사

용액공정이 가능한 유기반도체 물질은 다양한 인쇄공정인 Gravure printing, screen printing, 그리고 Ink-jet printing 과 같은 자유로운 인쇄 방법에 의해서 저가의 빠른 공정 속도로 다양한 전자기기를 제작하는 것이 가능하다는 그 장점을 가지고 있다. 유기물질의 고유의 특성인 낮은 전하 이동도 와 낮은 산화안정성 등의 단점을 가지고 있지만 기존의 무기물을 이용한 소자에 비해 초경량, 초박형, 저가격, 유연성, 저온 제작 등의 장점과 더불어 많은 연구가 진행되고 있어 최근에는 산화안정성이 크게 개선되었으며, 전하 이동도 면에서도 비정질 실리콘 기반 (>1cm2/Vs)의 소자와 견줄 수 있을 정도 까지 이르렀다. 특히, 용액공정용 유기박막 트랜지스터 (OTFTs) 는 유기전자의 기본이 되는 소자로써 RFID tags, 디스플레이 구동소자, 센서, E-paper 등 그 적용범위가 광범위 하여 그 관심이 증가하고 있다. Complementary Metal-Oxide-semiconductor (CMOS) 인버터는 여러 종류의 회로에서 가장 많이 쓰이는 소자이다. 이러한 CMOS는 p-형, n-형 의 두 종류의 반도체가 사용되는데 유기반도체의 용액공정을 통해서 제작하기 위해서는 여러 가지 인쇄 공정이 있다. micro-contact printing, Ink-jet printing 과 같은 다양한 Patterning 방법이 있는데 이와 같은 다양한 Patterning 방법들 중에서 잉크젯 인쇄 공정은 제작비용을 절감할 수 있으며16, 사용하는 물질의 낭비를 막을 수 있고, non-contact 방식으로 device를 제작할 수 있으며 기존의 photolithography 공정과는 다르게 마스크를 사용하지 않는 등 다양한 장점을 지녔다.1본 연구에서 개발된 OTFT는 P 형, N 형 모두 0.1cm2/V.s얻었으며, 인버터의 Voltage Transfer Curve역시 안정적으로 얻었고 10~15정도의 Gain을 얻었다. 더 나아가서, 본 연구에서 개발된 인버터를 5-stage ring oscillator circuit에 적용하여 약 30kHz정도의 유기물 Ring oscillators(R.O) 특성을 얻었다. 또한, Au Gate 메탈의 전도도가 RO의 스위칭 속도에 미치는 영향을 알아보기 위하여, 서로 다른 전도도를 보이는 두께의 Au 전극을 이용하여 RO의 전기적 특성을 평가해보았으며 전도도에 따라 달라지는 트랜지스터 및 유기물 링발진기 소자의 특성을 확인하였다. Solution processed conjugated molecules enable to manufacture various electronic devices by unconventional and cost effective patterning methods such as inkjet, screen, or gravure printing with a high throughput. Although the organic field-effect transistors (OFETs) using conjugated molecules as an active layer are not suitable for electronics requiring high charge carrier mobility due to intrinsic limitation of those materials, the advantage in manufacturing processes make them ideal for large-area, flexible, transparent, and disposable electronic devices such as drivers for flexible or transparent displays, digital circuits for radio frequency identification (RFID) tags, sensors, and memories. Moreover, the charge carrier mobility of state-of-the-art organic semiconductors is comparable with amorphous silicon so that it is expected that many applications will be replaced by cost-effective solution processed OFETs in near future. To realize advanced integrated CMOS circuits, those p-channel or n-channel conjugated molecules must be patterned. However, conventional patterning processes such as photolithography are not suitable since conjugated molecules are very weak under UV light illumination and cost of manufacturing facility is also very high. Therefore various novel patterning methods have researched such as micro contact printing or inkjet printing. Among those methods, inkjet has a variety of advantages such as removal of need for masks, which lead to cost-savings, efficient use of materials and waste elimination, non-contact deposition method (little contamination). Here we demonstrate high performance inkjet printed p-channel and n-channel top-gate/bottom-contact polymer field-effect transistors (FETs), and applications to elementary organic complementary inverter and ring oscillator circuits. We have obtained high field-effect mobility more than 0.1 cm2/Vs for both of p-channel and n-channel FETs, and the CMOS polymer ring oscillator showed very high operating frequency of 10 KHz. In addition, we did evaluation of ring oscillator circuit characteristics using different conductivities gate materials.

(The) role of strain in epitaxial oxide thin films for energy applications

한현 Pohang University of Science and Technology 2018 국내박사

Energy and environmental issues such as energy supplies, energy costs, environmental diseases and greenhouse gas emissions are spurring the demand for environmentally harmless renewable energy sources, including solar energy, hydropower energy, wind energy, tidal energy, biomass energy, geothermal energy. Recently, the strain in oxide thin film heterostructures has known that it greatly affect various physical properties, such as ferroelectricity, magnetic ordering, ion conductivity, electron mobility. The reason for this diverse change in the physical properties is mostly due to their strongly correlated properties in metal oxide thin films. In this regards, this thesis focuses on the energy related research based on metal oxide thin films using the flexibility of the property alteration. Among the renewable energy fields, the role of epitaxial strain in ferroelectric photovoltaics and exsolution for fuel cells will be discussed. The first topic is about ferroelectric photoltaic effect. Ferroelectric photovoltaics (FPVs) have drawn much attention owing to their high stability, environmental safety, anomalously high photovoltages, coupled with reversibly switchable photovoltaic responses. Among various factors influencing the FPV efficiency, narrow Eg and large polarization are known as the two most important factors. This is because the absorption of sun light by ferroelectric materials is limited by their Eg values and large polarization is crucial to efficiently separate the photo-generated exciton (electron-hole) pairs. Here, we present an easy and simple method of simultaneously achieving the above noted two important goals of FPVs, i.e., reduced Eg and enhanced polarization, by applying a film strain to epitaxially grown hexagonal YbFeO3 (h-YbFO) thin-film heterostructures. We further show the switchable FPV effect of these h-YbFO thin-film devices. The crystal structure of h-YbFO is featured by an alternative stacking of two distinct layers: one layer of corner-linked FeO5 bipyramids and the other layer of trivalent Yb3+ cations (Figure 1a). We demonstrate enhanced FPV efficiency by suitably exploiting the substrate-induced film strain. More explicitly, a compressive-strained h-YbFO/Pt/MgO heterojunction device shows ~3 times enhanced photovoltaic efficiency than that of a tensile-strained h-YbFO/Pt/Al2O3 device or multiferroic BiFeO3 which is known as the prototypic FPV. The origin of this enhanced PCE is investigated by examining the substrate-dependent band gap (Eg) and polarization (Pr), in conjunction with first-principles calculations. The second theme is about the exsolution of nanoparticles for renewable energy and catalysis. Catalytic metal particles dispersed on oxide surfaces play a key role in catalysis, energy conversion, and energy storage industries, including batteries, fuel cells, electrolysis cells. These catalytic metal particles have been prepared mainly by deposition techniques. However, the deposited particles mostly show limitation of particle size and distribution control, and degradation by agglomeration or carbon coking. The exsolution of the B-site ions from perovskite lattices (ABO3) under reduction conditions is emerging as an alternative, which shows possibility of in situ growth of nanoparticles. Compared to deposition procedures, this process shows higher cost- or time-efficiency, good thermal stability, and resistance to coking problems. However, the exsolution from stoichiometric ABO3 perovskites has primarily shown (i) a limited number of active cations, (ii) preferential occurrence within bulk (inside) rather than surface, and (iii) a slow speed of particle generation. To overcome these problems, the A-site deficient perovskites were employed to promote the B-site caion exsolution on surfaces, leading to both A-site and oxygen deficiencies that make easier ion diffusion and electron generation during the reduction by hydrogen. It was further revealed that voltage-driven reduction is two orders of magnitude faster than conventional reduction and yields a small particle size (~15 nm) and the highest population density of ~400 particles∙μm−2, resulting in outstanding electrochemical activity. To date, the studies on such exsolution have been performed mainly in bulk polycrystalline ceramics. Unlike bulk systems, thin-film heterostructures can induce strain in a film lattice because of the lattice mismatch between substrate and film, which affects various physical properties such as ferroelectricity, electron mobility, ionic conductivity and electrocatalysis. In particular, thin-film oxide fuel cells are currently attracting renewed attention owing to advantages of low temperature operation and portable device applications. Here, we demonstrate an unprecedentedly high degree of exsolution of nanoparticles in strained epitaxial thin films (particle density of 1177 particles∙μm−2, size of 5 nm) at a temperature as low as 550 oC. Compressive-stained films show a larger number of exsolved particles and higher thermal stability than tensile-strained films. The strain-driven in situ exsolution further offers rapid release of particles, good coking resistance, numerous particles even in μm-thickness, and wide tunability of particle growths. This finding opens a new way to design and development of catalytic functional materials and portable energy applications. The present studies will (i) offer a new standard for selecting substrates towards optimal design of ferroelectric optoelectronics and photovoltaic devices and (ii) opens a new way to design and development of catalytic functional materials and portable energy applications.

ABSTRACT A Comparison of Child Rearing Stress of Fathers between Ordinaryand Multicultural Families Having Preschool Children Han, Hyun Yi Department of Early Childhood Education, Graduate School of Education, KongJu National University Supervised by Prof. Oh, Eun Soon This study was to get basic data for a father education program which would decrease father's child rearing stress by comparing the child rearing stress of fathers in ordinary and multicultural families. For the purpose, following research questions were set up: Question 1) How are the child rearing stress of fathers in ordinary families having preschool children according to father's socio-demographic variables? Question 2) How are the child rearing stress of fathers in multicultural families having preschool children according to father's socio-demographic variables? Question 3) Is there any difference in the child rearing stress of fathers between ordinary and multicultural families having preschool children? Subjects for this study were 132 fathers in ordinary families and 127 fathers in multicultural families which have preschool children under the age five. All of them lived in O or B counties, Chungbuk. The instrument used in this study was the Parenting Stress Index/Short Form (PSI/SF) which had been developed by Abidin (1990) and translated by Cho (1998). This index, consisting of father, father-child, and child factors, measured the overall stress which might happen between parent and child. Collected data were analysed using SPSS/WIN Version 12. One-way ANOVA was utilized to detect group differences according to socio-demographic variables. And t-test was utilized to compare the child rearing stress of fathers between ordinary and multicultural families. The results of this study were as follows: First, statistically significant differences of father's child rearing stress were found in the father and child factors among socio-demographic variables. Regarding the job variable, fathers working in manufacturing showed high child rearing stress in the father factor. The group with lower income also showed high child rearing stress in all three factors. Second, with regard to fathers in multicultural families, no significant difference of father's child rearing stress was found according to father's age. In case of the job variable, fathers working in offices showed high child rearing stress in the father and child factors. Third, fathers in multicultural families had relatively higher child rearing stress than those in ordinary families in all three factors.
