이예경,박성희 사단법인 한국융합기술연구학회 2023 아시아태평양융합연구교류논문지 Vol.9 No.5

The purpose of this study is to analyze whether there is a difference in digital citizenship by college student’s individual variables(gender, grade level), and Internet self-efficacy. As a result of conducting a survey on 300 college students from two 4-year universities located in the metropolitan area, the data of 237 students who faithfully responded were used for analysis. In addition to descriptive statistics, a t-test, one-way ANOVA, and multivariate analysis were conducted to verify differences in digital citizenship by gender, grade level, and internet self-efficacy. The results are as follows. First, as a result of analyzing the difference in digital citizenship by gender, female students showed higher overall digital citizenship than male students. As a result of analysis by sub-area, female students showed higher scores than male students in participation, expressive production, collaboration, and care for others. Second, as a result of analyzing differences in digital citizenship by grade level, there was no difference between grade levels in the overall score. However, as a result of analyzing the difference between grade levels by sub-area, freshmen showed higher participation than other levels. Third, when analyzing differences according to the level of Internet self-efficacy, digital citizenship was higher in the top 50% group than in the bottom 50% group, and there were differences between groups in five sub-areas except care for others in the digital citizenship. Based on these results, the provision of education and related implications for the improvement of digital citizenship for college students were discussed. 본 연구는 대학생들의 개인 변인인 성별 및 학년과 인터넷 자기효능감에 따라 디지털 시민성에 차이가 있는지를 분석하고자 하였다. 이를 위해 수도권에 위치한 4년제 대학교 2개교의 대학생 300명을 대상으로 설문조사를 실시한 결과 성실하게 응답한 237명의 데이터를 분석에 사용하였다. 수집된 데이터에서 성별, 학년별, 인터넷 자기효능감 수준에 따른 디지털 시민성 차이 검증을 위해 t검정, 일원분산분석, 다변량분산분석을 실시하였으며, 그 결과는 다음과 같다. 첫째, 성별에 따른 차이를 분석한 결과 여학생이 남학생보다 전체 디지털 시민성이 높게 나타났으며, 하위 영역별로 분석한 결과, 참여, 표현제작, 협업, 타인배려 영역에서 여학생이 남학생보다 높게 나타났다. 둘째, 학년에 따른 디지털 시민성 차이를 분석한 결과, 전체적으로 학년 간 차이가 나타나지 않았다. 하위 영역별로 학년 간 차이를 분석한 결과, 참여에서 1학년이 다른 학년들보다 높게 나타났다. 셋째, 인터넷 효능감 수준에 따른 차이 분석에서는 하위 50% 그룹보다 상위 50%의 그룹에서 디지털 시민성이 높게 나타났으며, 디지털 시민성 하위 영역에서도 타인배려를 제외한 5개 영역에서 그룹 간 차이가 있는 것으로 나타났다. 이와 같은 결과를 바탕으로 대학생을 위한 디지털 시민성 향상을 위한 교육 제공 및 관련 시사점을 논의하였다.

This study was carried out investigate the effect of water quality and the kind of media on the in vitro development of 1-cell and stage mouse embryos. $F_1$ hybrid mice were superovulated and timely mated. 1-cell stage and 2-cell stage mouse embryos were recruited and taken into Ham's F-10 or m-KRB media which was made of two of two kinds of water having different quality, highly purified water and tap water. 2-cell stage embryos grew up well in vitro to blastocyst or hatching blastocyst regardless of the composition of culture media, but 1-cell stage mouse embryo didn't develop well to blastocyst or hatching blastocyst in simple media like m-KRB. These results meant in vitro devleopment of 1-cell stage mouse embryo neded complex media like Ham's F-10 which contained abundant protein components. In case of quality control for water, in vitro fertilization program. observation of in vitro development of 2-cell mouse embryos up to blastocyst or hatching blastocyst media such as m-KRB would be efficatious in detecting the difference of water quality.

학습자의 경험 분석을 통한 플립 러닝의 재해석

이예경,윤순경 한국공학교육학회 2017 공학교육연구 Vol.20 No.1

This paper explored how university students viewed flipped learning from their own perspectives. Using qualitative research methods, 5 students from a Computer Graphics course at a mid-scale university in Seoul were interviewed for this purpose. Researchers collected data about their learning experiences, emotions, and reflections about flipped learning in general and its components such as online materials, in-class activities, and instructor guidance. Research findings indicated that students were not so much conscious about the unfamiliarity of the class, the increased work load, nor the online lectures. They rather prioritized ‘what they could actually learn’ from the course, and thus defined flipped learning as a method which enabled students to constantly check and fill in the gaps in their learning through team-based activities and prompt feedback from the professor. A combination of students’ positive attitude and active participation in team-based activities, the overall atmosphere of the department which supported interactivity and collaboration, the professor’s emphasis on learning-by-doing and student-centered learning appeared to form their notions of flipped learning. The use of technology did not appear to heavily impact students’ conceptions of flipped learning. Researchers suggest that pedagogical beliefs of the professor, culture surrounding the learner, and the good match between the course content and instructional strategies are central for designing a successful flipped learning class.

This study was conducted to investigate the quality characteristic of bread added with 0, 2, 4 and 8% liquid calcium acetate(LCA-breads) to the dough prepared with brown rice, vinegar and ash of black snail replacing wheat flour. The pH of the dough was 5.38 in control and 5.39~5.42 in the LCA-breads, which showed that the higher the content of LCA, the higher the pH. There was no big difference of the baking loss between control (10.73%) and LCA-breads(10.11~10.81%). The loaf volume index was 7.12 in the control, 7.18 in the 2% LCA-bread, while the index was 6.22 in the 4% LCA-bread, 5.80 in the 8% LCA-bread. Calcium content was 16 ㎎% in the control, 30, 60 and 120 ㎎% in 2, 4 and 8% LCA-bread, respectively. The hardness, gumminess and brittleness of LCA-breads were higher, while springiness and cohesiveness were lower than that of the control. In the LCA-breads, L^(*) values were lower and b^(*) value was higher than those of the control, while there were no significant difference in a^(*) values. Increasing the LCA, air cells were bigger and irregular, and starch matrix was unstable. There were no significant difference in sour and bitter taste. The scores of stickiness of the 2~4% LCA-breads were similar to that of the control and higher in the 8% LCA-bread. The scores of the flavor and overall taste in the LCA-breads were similar to the control, while the values were lower in the 4~8% LCA-breads. The shelf-life evaluated by the number of moldy spots was not different between the control and 2% LCA-bread, while it was extended two times in 4% and three times in the 8% LCA-bread.

L.V. Beethoven Piano Sonata op.81a의 形式構造의 分析과 心理的인 描寫에 關한 考察

이예경 安東大學 1985 安東大學 論文集 Vol.7 No.1

In order to reveal the profoundness of emotional content and self-expression, Beethoven composed this piano Sonata op. 81a which is programmed each movement and the only one among his 32 Piano Sonatas. The introduction of program music was started in the first time by Beethoven in the history of music. 1) First movement; sonata form. On the first three notes, Beethoven wrote 「Lebewohl」 which does not mean a generally expressed word of departure but implies his sufferings for the departure from his loved ones with full of missing emotion. The significance of 「Lebewohl」 is manifest throughout this sonata. In the exposition section, Beethoven presented the idee fixe and leading motive music, which was influenced on the later composers and modern music. It is not cleared whether he did it consciously or not. In the development section, 「Lebewohl」 theme and first theme are developed in a motive and there is no planned fancy, which is expressed in other sonatas. In the Coda section, performance of the tonic and dominant with his hands at the same time made the theorical convention broken and made the harmony disordered. The bitonality, which is one of modern music features is predicted by Beethoven. 2) Second movement, which is sonata form omitted a development section. It serves as the introduction of the third movement. In the second movement, the loneliness of absence and the anticipation of return are well expressed. 3) Third movement; As the sonata form, it is the introduction with 10 measures. Emotion in the excess of ecstasy for his loved one`s return, embrace, dialogue on the memory during absence, friendship and harmonized spirits are well expressed in this movement. In the first movement, 「Lebewohl」 motive takes very important role but nothing in the second movement and a little in the third movement. Beethoven attaches great importance to the musical contents and composition rather than description. He must be a great musical master in the history of music. He wrote the expression marks in German and Italian together in the first time, this attempt shows that Beethoven owns the subjectivity as German.

Utilizing AI and Big Data in Education: The Current State and Future Directions

이예경,유진은 한국열린교육학회 2021 열린교육연구 Vol.29 No.4

This study discusses the current state of, future directions for, and challenges of research on AI and big data in education. To accomplish this goal, first, a review of the state of research on learning analytics, large-scale data analysis, text mining based big data analysis, multimodal data analysis, and game-based learning was conducted. Based on the review researchers suggested future directions as the following: 1) The use of learning analytics in elementary and secondary schools should be promoted by developing instructional models to analyze learning analytics data and establishing an integrated system for data collection at a national level, 2) Large-scale data from various sources should be merged together into educational big data sets so that researchers can extend the potential for exploring complex and critical issues in our education system, 3) More research on sentiment analysis via text mining is needed considering its potential for providing insight into identifying students’affective states and administering effective interventions, especially for elementary and secondary school students. Despite the promising uses of AI and big data analysis for solving educational problems, the challenges we face are, first, disbelief about the contributions that AI and big data can offer to the field of education, second, the lack of government initiative for organized data collection and analysis, third ethical concerns about biases and privacy matters, and finally, the shortage of educational AI and big data experts.

무게조절 테크닉을 중심으로 한 피아노 연주법에 관한 연구

이예경 安東大學 1997 安東大學 論文集 Vol.19 No.1

피아노란 악기는 체격이 큰 서양인들에 의하여 발달된 악기이며, 작품들 또한 대부분 서양 남성들의 손 크기에 맞게 작곡되었다. 그리고 발달되어 무거워진 현대의 피아노는 손가락 중심 연주법으로는 힘이 들어 무게조절 연주법을 연구하기에 이르렀다. 따라서 작은 체격과 작은 손을 가진 동양인, 특히 여성들에게는 이 건반의 무게가 무척 부담이 된다. 그러므로 작은 손을 가진 여성들은 무게조절 연주법을 보다 많이 이해하고 활용해야만 이 어려움을 극복해 나갈 수 있다고 본다.
