Synthesis and Mechanical Characterization of Metallic Glasses with High Elastic Deformation for Stretchable Encapsulation Films

Sun-Young Park Graduate School of UNIST 2019 국내박사

Metallic glasses have been researched expensively due to their remarkable properties such as excellent corrosion resistance, large elastic limit and strength, unique soft magnetic properties, wear resistance etc. One of the most attractive aspect of metallic glasses is impressive suite of mechanical properties. Compared to crystalline material with similar composition, metallic glasses exhibit significantly high elastic limit and tensile strength. On the other hand, they have a lack of tensile ductility that results in sudden and catastrophic failure due to intrinsic properties of atomic arrangement, disordered structure. Considerable work has been aimed at improving the tensile ductility of metallic glasses, and the development of glass-matrix composites with high toughness and tensile ductility is being explored. Two basic techniques are employed to attain high tensile ductility: introducing a softer secondary phase in the metallic glass matrix to induce generation of local shear banding around the secondary phase and reducing its external dimensions to suppress a propagation of shear bands or occur homogeneous flow instead, leading to enhanced strength and ductility. Since there are limited structural applications for monolithic metallic glass with dimensions of the order of 100 nm, nanolaminates with alternating layers of metallic glass (with dimensions of 100 nm or less) and another material have been suggested as a more practical material. Metallic glass-based nanolaminates with proper interfacial material and optimum layer thickness can exhibit improved strength and ductility by utilizing size-dependent homogeneous flow of metallic glass. In this study, mechanical behavior of nanolaminate with metallic glass and graphene is investigated. Nanolaminate with alternating layers of metallic glass and graphene is fabricated by repeating deposition of metallic glass by sputtering and transfer of chemical vapor deposition-grown graphene. In situ micro-tensile tests reveal that the addition of a very small fraction of graphene in the nanolaminate improve the elastic modulus and yield strength of the nanolaminate, comparing with those of the monolithic metallic glass. The nanolaminate also shows enhanced tensile ductility by homogeneous flow in the metallic glass layers. Using mechanical properties of metallic glass, metallic glass film is investigated for stretchable encapsulation material. Encapsulation is necessary to protect devices vulnerable to moisture and oxygen and as stretchable and wearable devices are developed, stretchability is also required in encapsulation materials. Amorphous structure of metallic glass material is advantageous in encapsulation film since diffusion path of moisture or oxygen vapor is increased comparing to crystalline or organic materials with grain boundary or large size of defects. The ternary metallic glass thin film with high thermal stability is fabricated by co-sputtering process. Electrical Ca test is performed to evaluated diffusion barrier characteristic and reveal metallic glass in the system of CuZr-Ti has water vapor transmission rate of 10 -3 order. Stretchability of ternary metallic glass thin film is evaluated as 4 % through in situ tensile testing and cyclic stretching testing, showing feasibility for stretchable encapsulation material.

A study on the expression and psychological understanding of FEAR shown in the works of art Park, Sun-Young Major in Arts Education Graduate School of Education Korea University Supervised by Prof. Rhee, Ki-Bong Before modern times, most of the expressions of fear shown in a work of art have largely been modified as the term of ''anxiety''. However, the direct expression of excessive aggressiveness and cruelty shown in modern art will make more appropriate use of the term of ''fear'' with a clear concrete object of threat rather than the term of ''anxiety'' as the unclear fear without any concrete object of threat. It is because some forms shown in the art related to fear are thought to provoke an instantaneous sense of fear even momentarily rather than bring about an unclear sense of uneasiness. Fear attracts a person''s attention as a new genre in a cultural area today. The term of ''fear'' in fine art is replaced by an academic term symbolized by psychologists, which is also applied to explaining the works of expressing it. The typical examples include Sigmund Freud''s concept of the uncanny -anxious strangeness- and Julia Kristeva''s abjection-humbleness and sickeningness. As the key word in this thesis fear is emotional condition of terror and dread. It responds to a particular object and situation, but occurs in most of people. Thus, it is the universal emotion and object to overcome. Freud who associated it with human instinct said that it was generated by the fear felt by human consciousness for unsatisfied, oppressed desire to be released to the outside. Fear is the one which most of people want to turn their faces away from and evade, whether consciously or unconsciously. However, in the area of art, a group of artists create works by using it as their own expressive language. This study presupposes the question of ''why'' regarding it, and aims at clarifying the understanding of their inner motives. It did not use an analysis of artists or an aesthetic viewpoint but a psychological approach. It presented from a consistent viewpoint the theories of the psychologists with the view that fear was associated with human oppressed instinct. The researcher derived the following conclusions from the study. fear shown in a work of art is not from the outside but from the artist''s own inside by human alienated instinct. Artists recognize themselves as fully integrated beings and try to achieve the purpose of existential pursuit through accepting and acknowledging instead of denying and oppressing consciously the fact that fear is generated in their own inside. The works which express it also reflect the times and the society which they belong to, from which I could also get the conclusion that the works were intended to awaken human violence and cruelty shown by the times and the society. If one aspect of human alienated, oppressed instinct generates fear as mentioned as a presupposition and conclusion in this thesis, I think that more studies on what are symbolized by the works which express fear will need to be made in various domains, and expect that more useful, better studies will be made later.

ABSTRACT The Effect of Teaching English Using Multimedia for Improving Listening and Reading Skills Park, Sun-Young Major in English Education The Graduate School of Education Kookmin University The purpose of this study is to examine the effect of blended learning method via multimedia such as CD-ROM title for improving listening and reading skills of young learners. For these purposes, the relationship between the multimedia and the second acquisition theories should be investigated to search for the ways to find the ways of designing language teaching methodology and the teachers need to select the suitable materials that maximize the teaching process. Teaching methodology using multimedia has a lot of benefits but also it has limitation so it is required to design blended English learning model to make the lesson effective. For this study, 24 elementary school students who study in a private English institute were chosen and they were divided into 2 groups after the prior test and questionnaire surveys. The questionnaire surveys consist of three categories like students' interests, self-motivated and satisfaction of using computer software, Rosettastone. They had similar proficiency levels, and their attitude toward English learning and using multimedia was similar, too. To conduct this experiment Rosettastone computer software was used to be applied to blended learning and individual e-learning. It is a computer software that is based on Dynamic Immersion Method that provides abundant authentic materials so that young learners learn foreign languages like the way of acquiring their first language. To measure the result of experiment, both groups were taught by two different ways for 5 weeks. The experimental group was taught with the blended learning applications(mixed traditional face-to-face learning and e-learning) that used Rosettastone computer software, while the control group took the courses of CD-ROM title, Rosettastone, during the self-study time individually. After conducting the experiment both experimental group and the control group were asked to do a survey and tested on vocabulary, listening and speaking skills and evaluated. Three results of this research are as follows: First, teaching English by using blended learning method gave the learners affirmative effects in terms of the affective factors. Even though both groups didn't show the evident effect in learning English through blended learning, the experimental group's gradual improvement in the interest of blended learning using Rosettastone computer software makes it possible to expect the positive results in long-term learning process. But the self-motivated attitude has dropped in both groups. Especially when a progress chart was given to the control group for tracking the scores and the learning process they complained a lot. Second, teaching English by using blended learning method helped the learners to improve their vocabulary mastery. The vivid pictures and authentic materials of the CD-ROM title helped the learners to build their vocabulary effectively. The experimental group who played Picture Cards game could get better test results because they could have more chances to speak out the vocabulary and understand the meaning of the words with the teacher's explanation. Doing guessing game, the learners could have time to remind the vocabulary and the learners could hold them in their long-term memory. Third, teaching English by using blended learning method helped the learners to improve their listening and speaking skills. The audio-visual provided the learners to be exposed to the target language and gave more chances to use target language. By applying the blended learning method, the learners could pursue learning English without distractive factors such as simple mechanical repetition and the lack of communicational interaction. The activities such as 'completing the dialogue looking at the pictures and picture description' that the experimental group had motivated them to speak freely and it made them fluently. Using multimedia for teaching English is wide-spread and a lot of courseware is being developed. In addition, Korean government announced that it will move forward with 'SMART Education' plan, that is to encourage the public schools to apply information technology in teaching so as to cultivate men of talent. Among overflowing softwares, it is necessary for the teachers to select suitable materials that maximize teaching in class. And by designing the blended English learning model teachers can apply the multimedia easily. This will help the learners to improve their English skills effectively.

Abstract A Study on the Relationship between Speed and Accuracy, and Strategy Use in Reading Comprehension. Park Sun-Young Department of English Language Literature The Graduate School Suncheon National University Advisor : Prof. Lee Hwa-Ja The purpose of this study was to identify the relationship between reading speed and accuracy, and strategy use in reading comprehension. In order to look into the relationship in terms of English proficiency level, 123 students in two schools, one in high level, the other in mid level, were chosen. Trial examinations and the questionnaires on reading strategics by Oxford(1990) and Lee Hyo Eung were employed. The results of this study were as follows : The upper group in a high-level high school got the highest grade on the speed and accuracy of reading. When the upper groups of two schools were compared. there was a big difference in the speed(M=11.66) and accuracy(M=18.45). But it was a marked feature that the reading speed of the middle group was slower than one of the lower class in mid-level high school. It implied that the lower group gave up the examination in advance and the middle group tried to solve it to the end. When they were analyzed by each major, liberal arts and natural science, the middle groups in each school got the lowest grade in the speed of reading. By these results, it was revealed that the middle group in the mid level high school. except the high-level high school, had the weak point in the speed of reading. In reading strategies, all the groups preferred the top-down strategies but they avoided the bottom up strategies. This result implied that students mostly studied reading parts because they appeared in the college-entrance examination. The reason made students neglectful of grammar parts universally. So, it seemed that they revealed their weak point in solving grammar parts and they avoided to study them.
