Shared Reading을 통한 영어 동화 지도가 초등학습자의 영어 읽기 능력, 흥미도와 동기부여에 미치는 효과
권초롱 공주대학교 교육대학원 2014 국내석사
This study examines how Shared Reading during after school class affects elementary students' English reading ability and attitude. It provides basic data which can help beginning reader. In this study, we mainly used the Shared Reading as the method for reading instruction, and additionally examined if the improved reading ability level of each group within the experimental group differed as well. To perform this study, we selected two groups out of T elementary school respectively as experimental group and controlled group. In the former class, the Shared Reading activity was carried out with 3 English storybooks during the after school class for three months and, in the latter class, it was conducted with CD-ROM title provided as an auxiliary textbook by the Ministry of Education & Human Resources Development during the same period. The result was produced through a statistical analysis by SPSS and Excel program on basis of the test results on the students' English reading skills and attitude before and after the study. The results of this study are summarized as followed. First, the experimental group who read by using English storybooks showed a meaningful improvement in their reading ability for elementary students. The effective use of the storybook stimulated the students’ curiosity and aroused their interests. It also helped them understand the story content and have confidence to read aloud. Second, the learners in the experimental group showed significant in terms of affective factor, interest and motivation. The use of stories in the classroom had a positive effect on students' interests, class participation. In conclusion, instruction by using Shared Reading method showed positive effects on elementary students' reading ability, their interests, motivation. These results suggest that English storybooks are effective tools to improve reading ability as well as their affective factor for elementary students. On the basis of these results, we intend to make the following suggestions on the English reading activities for the reading beginners in elementary school. First, this experiment can receive different results in agricultural area, fishing area. If the 3rd grade, 4th grade and 6th grade students participated in the experiment, then the results may vary. Therefore, more long-term studies are needed. Second, each class or school library and local library must retain various English storybooks to satisfy children's interest. Third, we need to make sure English storybook reading activities continue as educational activities connected with the family and the school and shared with the teachers and the parents.

대학생의 외향성이 주관적 안녕감에 미치는 영향 : 성인애착의 조절효과를 중심으로
본 연구의 목적은 대학생들의 외향성과 주관적 안녕감의 관계에서 성인 애착의 조절 효과를 살펴보는 것이다. 이를 위해 대구·경북 지역에 위치한 4개 대학에 재학 중인 334명의 남녀 대학생을 대상으로 연구를 진행하였다. 수집된 자료는 SPSS 22.0 for windows를 이용하여 기술통계와 상관분석을 실시하였고, 조절효과 검증을 위해 Hayes(2013)가 개발한 SPSS macro 프로그램인 PROCESS를 활용하였다. 주요 결과를 살펴보면 다음과 같다. 첫째, 외향성과 애착불안, 애착회피, 삶의 만족, 긍정정서, 부정정서 사이에는 유의한 상관관계가 있었다. 둘째, 애착회피는 대학생의 외향성과 긍정정서의 관계를 조절하는 것으로 나타났다. 즉, 애착회피 수준이 낮을 때 외향성은 긍정정서에 유의한 영향을 미치는 것으로 나타났다. 또한, 외향성과 주관적 안녕감의 관계에서 애착불안의 조절효과는 유의미하지 않은 것으로 나타났다. 이러한 결과는 외향성과 애착불안이 서로 독립적으로 주관적 안녕감에 영향을 미치는 것으로 해석할 수 있다. 본 연구 결과는 외향성이 애착 회피가 낮을 때만 긍정정서에 유의한 영향을 미친다는 것을 밝힌데 의의가 있다. 또한 본 연구 결과는 높은 외향성을 가지고 있음에도 불구하고 주관적 안녕감이 낮은 대학생들의 긍정정서를 증진시키는데 기여하였다. The purpose of this study was to examine the moderating effects of adult attachment between extroversion and subjective well-being among university students. The subjects of this study were 334 university students attending four universities in Daegu and Gyeongbuk provinces. The collected data were analyzed using descriptive statistics and correlation analysis using SPSS 22.0. PROCESS, a SPSS macro program developed by Hayes (2013), was used to examine the moderating effects. The major findings are as follow. First, there was a significant correlation between extroversion and attachment anxiety, attachment avoidance, life satisfaction, positive emotion, and negative emotion. Second, attachment avoidance was found to moderate the relationship between the extroversion and the positive emotions among the university students. In other words, when the level of attachment avoidance was low, extroversion had a significant effect on positive emotion. In addition, the moderating effect of attachment anxiety was not significant in relation to extroversion and subjective well-being. This result can be interpreted that extroversion and attachment anxiety independently influence subjective well-being. The results of this study contribute to enhance our understanding the context that extroversion have significant effects on positive emotion only when attachment avoidance was low. This study has implications for promoting positive emotions among university students who have low subjective well-being despite their high extroversion.

Synthesis of catalyst supports by electrospinning for durable PEMFC
권초롱 Green School Graduate School of Energy and Environ 2013 국내석사
Polymer Electrolyte Membrane Fuel Cell (PEMFC) is electrochemical energy conversion devices that react hydrogen and oxygen to produce electricity. Carbon black is the typical catalyst support material in PEMFC due to its large surface area, high electrical conductivity. However, during fuel cell start-up and shut-down, carbon support is subjected to serve corrosion in the presence of water. Therefore, it would be desirable to switch to non carbon support material such as metal oxide. TiO2 have been attractive as supports due to stability in fuel cell operation atmosphere, low cost, commercial availability, stability in water, and the ease to control size and structure. Nano structured materials such as nanofibers have received much attention as catalyst supports for PEMFC. Recently, the electrospinning technique has been used as synthesis for support materials. However, TiO2 have low electrical conductivity. Therefore, it is important to explore possibilities for synthesizing TiO2 with good electrical conductivity. In this study, electrospun TiO2 nanofibers as a catalyst support have high electrical conductivity in different calcination temperature for PEMFC. Moreover electrospun Nb-doped TiO2 (Nb-TiO2) nanofibers as a catalyst support for cathode in the fuel cell is prepared. Electrochemical properties of Nb-TiO2 supported cathode catalyst are evaluated and compared with those of carbon supported catalyst.
