마임 창작 활동이 초등학생의 신체적·창의적 자기효능감에 미치는 영향
최청아 춘천교육대학교 교육대학원 2020 국내석사
본 연구는 마임 창작 활동의 자기효능감 향상과의 관련성을 규명하는데 그 초점을 두고, 프로그램이 초등학생의 신체적·창의적 자기효능감 향상에 미치는 영향을 실험적으로 검증하는데 그 목적이 있다. 연구의 대상은 D초등학교 5,6학년 183명을 대상으로 실험집단 137명과 통제집단 46명을 선정하여 구성하였다. 실험집단에 적용된 프로그램은 체육과 탐구학습모형이 적용된 마임 창작 활동으로, Claude Kipnis(1974)의 마임의 기능적 요소를 익힐 수 있도록 새롭게 구성한 것이다. 먼저 실험집단과 통제집단의 학생들에게 자기효능감 검사를 사전 실시한 후 실험집단만 마임 창작 활동을 1주일에 2회씩 10주 동안 투입하였다. 실험처치 후 연구문제를 해결하기 위해 실험집단과 통제집단에게 사후 자기효능감 검사를 실시하였다. 수집된 자료는 SPSS 25 프로그램을 이용하여 통계처리하였다. 이 연구에서 수집된 자료를 분석하고 나타난 결과는 다음과 같다. 첫째, 프로그램 실시 여부에 따른 신체적 자기효능감의 차이 검증은 유의한 것으로 나타났다. 따라서 마임 창작 활동이 신체적 자기효능감을 호전시키고 유의한 차이가 나타났음을 알 수 있다. 둘째, 신체적 자기표현 자신감은 실험집단이 통제집단보다 큰 폭으로 상승하여 유의한 차이를 보였지만, 인지된 신체능력의 두 집단 차이는 유의하지 않았다. 셋째, 프로그램 실시 여부에 따른 창의적 자기효능감의 차이 검증은 유의한 것으로 나타났다. 따라서 마임 창작 활동이 창의적 자기효능감을 호전시키고 유의한 차이가 나타났음을 알 수 있다. 넷째, 창의적 사고 자기효능감과 창의적 수행 자기효능감 모두 실험집단의 사전-사후에서 유의한 차이를 보였다. The focus of this study is to demonstrate the relationship between mime creative activities and self-efficacy improvement and the purpose is to investigate the effects of improving the physical and creative self-efficacy of elementary school students. The results of this study are as follows. First, the effects of physical and creative self-efficacy on elementary school students were experimentally verified. The study subjects were 183 grades 5, 6 of D elementary school. and carried out by selecting 137 students as experimental group and another 46 students as a control group. The program applied to the experimental group is the instructional models in physical education and I made and configured it anew to learn the Claude Kipnis's functional elements of the mime. After testing self-efficacy to both experimental and contrl groups at first, I tested mime creative program to the experimental group only for 10 weeks, and 2 times per week. Then, I carried out self-efficacy test to the experimental group and the control group in order to resolve the research matter. The collected materials were gathered as data by SPSS 25 program. The following results have come out after analyzing the collected data in this study. Firts, after testing program, the experimental group had higher scores of physical self-efficacy than the control group. therefore, mime creative program effects to Improvement of physical self-efficacy. Second. There was a statistically significant wide gap in physical self presentation confidence between the experimental group and the control group. but perceived physical ability was not. Third, after testing program, the experimental group had higher scores of creative self-efficacy than the control group. therefore, mime creative program effects to Improvement of creative self-efficacy. Fourth, There was a statistically significant gap in creative thinking self-efficacy, creative performance self-efficacy between the experimental group and the control group.

형광 on/off 제어용 pH민감 탄소양자점 기반 암세포 및 박테리아 진단 연구
최청아 한국교통대학교 일반대학원 2019 국내석사
We will conduct a study of the diagnosis of cancer cells and bacteria based on pH-sensitive carbon dots fluorescent on/off. It can be diagnosed quickly and accurately for a variety of diseases and will have a unique treatment effect. First, we studied target drug delivery based on the fluorescent nanoparticles, which are highlighted by bio imaging systems. We based on HA, the cancer-cell target polymer, to form a pH-sensitive carbon positon by combining boron esters with other polymers including catechol. Afterwards, the fluorescence was turned off using the MnO2 nanosheet, which acts as a quencher, and the anti-cancer drug Pacliteaxel was loaded. This has a targeting for cancer cells using HA, effectively diagnosing cancer cells using low pH in cancer cell environment and high glutathione concentration, and a high cancer cell specific drug release. The following study was conducted on the detection of bacteria based on fluorescent carbon dots. The boronic acid was synthesized with a fluorescent dye containing a diol to synthesize a carbon dots with a fluorescent pH sensitive bond. Polysaccharide compounds present in bacterial cell walls contain large amounts of diol, which are capable of both fluorescent dye and ligand exchange of synthetic carbon dots. Therefore, the presence of bacteria gives rise to fluorescence and allows effective detection of bacteria. The combined carbon advantage also includes the ability to detect even a small amount of bacteria quickly because they have lower detection limits than traditional bacterial particles.
