교양 영어 교육에서 플립드 러닝이 학업성취도 및 수업 만족도에 미치는 영향

오현영,구정모 한국지식정보기술학회 2016 한국지식정보기술학회 논문지 Vol.11 No.6

In Korea, universities have been providing liberal arts education to improve their English proficiency. There are problems such as lack of response to various levels of students, native English professors' lack of ability of teaching and classroom management, and rigidity of teaching methods. Recently, it has been trying to induce learner participation by using flipped learning in domestic and foreign universities considering learners' level and interests. In Korea, however, there are not many empirical studies using flipped learning in general English courses at universities. In this study, we designed the flipped learning lesson and developed the necessary apps for English education, PowerPoint slides, and other instructional materials and applied them to the actual classroom. A traditional teaching method and a flipped learning method were applied to control and experimental groups for sixty-three students who attended in general English classes at a local university. There were no meaningful differences in academic achievement and class satisfaction between the two groups. However, the students in the experimental group responded very positively to the before-class learning and overall satisfaction in the assessment of awareness for flipped learning. We hope this study will contribute to the application and dissemination of flipped learning in general English courses at universities.

온라인 수업 평가에 미치는 중요 요인 분석 -일본어 교과 수업을 중심으로 -

오현영 한국일본어교육학회 2023 日本語敎育 Vol.- No.103

본 연구는 일본어 회화와 작문 수업을 중심으로 온라인 수업 평가에 미치는 중요 요인과 교과별로 중요시되는 요인을 비교 분석하였다. 그 결과 평가에 미치는 중요 요인으로는 요인1 상호작용, 요인2 기기조작, 요인3 학습효율, 요인4 수업편이성 요인이 도출되었다. 다음으로 교과별로 각 요인에 대한 평균치와 차이를 보기위해 t검정을 실시하였다. 그 결과 유의차가 보인 요인1 상호작용은 회화수업에서 더 중요시되는 것을 알 수 있고, 요인4 수업의 편이성 요인은 작문 수업에서 더 중요시되는 결과였다. 이상의 결과로부터 교과에 상관없이 온라인 수업 평가에 상호작용, 기기조작, 학습효율, 수업편이성이 평가에 미치는 큰 요인으로 생각되며 온라인 수업 개선을 위해서는 위의 4가지 항목에 대해 좀 더 다양한 질문지를 작성해야 할 것이다. 또한 교과별로 평가에 미치는 요인이 다르다는 점에서 수업 평가에도 교과에 따라 상이한 질문지를 제시하거나 질문지 항목의 내용을 교과에 맞게 작성하는 것이 온라인 수업의 개선으로 이어질 것이다.

오현영 한국일본언어문화학회 2022 일본언어문화 Vol.59 No.-

This paper compared and analyzed the results of a questionnaire about online lessons, focusing on Japanese class. The results obtained in this study are summarized as follows. First of all, regarding online class in general, students are (1) emphasize three factors largely technical, interacting,Physical aspects. Next (2) Real-time online class are recorded lessons It is possible that it cannot be solved with, but in the case of writing class (J3), Real-time online class. However, there is not much problem in the progress of the lesson, and the efficiency of the lesson is improved to make up for the weaknesses in the class. There is also a point to be gained. In the case of the last conversation class (J1, J2), (3) Recorded class will be launched. It is possible to repeat the practice of pronunciation and listening, but feel uneasy about practicing alone. It was seen that it could be supplemented by online lessons. Therefore, the conversation class will be recorded on the grammar side,and can be conversation practice easier. But on the other hand, feel anxious about pronunciation and practice. In online lessons, the interaction with students and professors depended on the quality of the lessons.

Removal of Heavy Metal Ions from Wastewater by Polyacrylonitrile based Fibers: A Review

오현영,이재훈,라즈쿠마파텔 한국막학회 2019 멤브레인 Vol.29 No.3

Environmental pollution caused by the presence of heavy metal ion from growing industrialization or from leaching is increasing area of concern. There are several area of water purifications but among them adsorption on the functionalized polymer fibers is efficient and cost-effective method. Polyacrylonitrile (PAN) is exciting polymer due to the presence of excessive functional group which can be easily transformed for metal ion adsorption. PAN can be easily electrospun to prepare nanofiber that have higher surface area leading to better metal ion removal. Composite PAN fiber is yet another type of polymer covered in this review for waste water treatment.

初対面場面における自己開示に関する意識調査 - 韓国人日本語学習者と日本語母語話者を対象に -

오현영 한국일어일문학회 2020 日語日文學硏究 Vol.112 No.-

In this study, the purpose of the study is to reveal what kind of rituals the Korean learners of Japanese and the native speaker of Japanese are making conversation with first-timers while giving consideration to first-timers. Until now, prior research has focused only on language and nonverbal elements. In addition, the focus is on the ignition itself, such as the consideration needed to actively carry out the dialogue and the consideration needed to make the other party understand more deeply, but the specific method is not studied until further. There, the main study conducted a questionnaire survey on self-initiated fires. The questionnaire prepared 21 items on self-initiated and 10 items on self-initiated recipients. The assessment was assessed in Step 7 to the extent of relevance for 31 items. In order to avoid the learning effects that can be done while answering questions, we prepared a reversal from the first half of the question. The survey collaborators targeted 70 Japanese students enrolled in Japanese universities (one in Ibaraki Prefecture), 15 of them male, 55 female, 70 Japanese language students enrolled in Korean universities, 20 of them male, 50 female, and those who have no experience studying abroad. The average age of a Japanese student (J) is 20 years old. What was revealed in the survey was a marked difference in consideration of ignition rather than as a listener. Specifically, compared to J, who cares about the other person, it is either an interest in the opponent or an activism that serves as a consideration for K. However, the question remains whether it will appear in the conversation as it is a survey of consciousness, not a real conversation. Therefore, it is thought that there is a need to conduct both dialogue and questionnaires investigation 본 연구에서는 한국인 일본어 학습자와 일본어 모국어 화자를 자기개시 발화에 관한 질문지 조사를 통해 어떤 의식을 바탕으로 초면인 사람과 배려를 하면서 대화를 하는지 밝히는 것을 목적으로 했다. 지금까지의 선행연구에서는 언어, 비언어적 요소에만 집중되어왔다. 또한, 대화를 적극적으로 진행하기 위해서 필요한 배려와, 상대방에게 자신을 보다 깊게 이해시키는 배려 등 발화 자체에 집중되어있는 것도 있지만, 구체적인 방법에 대해서까지는 연구되어 있지않다. 거기서, 본연구에서는 자기개시의 발화에 관한 질문지 조사를 실시했다. 질문지는 자기개시에 관한 항목 21개, 자기개시의 받는이에 관한 항목 10개를 준비했다. 평가는 31개 항목에 대해서 어느 정도 적합한지를 7단계에서 평가받았다. 질문에 답하는 동안 할 수 있는 학습효과를 피하기 위해 문항의 전반과 역전시킨 것을 준비했다. 조사 협력자는 일본 대학(이바라키 현 1개)에 재적하는 일본인 70명, 그 중 남자 15명, 여성 55명, 한국 대학에 재적하는 일본어 전공 학생(이하 K)70명, 그 중 남자 20명, 여성 50명, 유학 경험은 없는 사람을 대상으로 했다. 평균 연령은 일본인 학생(이하 J)20.5살 한국 학생은 20세이다. 이번 조사에서 밝혀진 것은 초면에 상대에게 듣는 사람으로서의 배려보다 발화에 관한 배려의 차이가 현저하게 나타났다. 구체적으로는, 상대를 배려하는 J에 비해, 상대에게 흥미를 나타내는 것이나 적극성이 K에게는 배려로 작용하는 것이다. 그러나 실제의 대화가 아니라 의식에 대해 조사한 것이기 때문에 그대로 회화에도 나타날지 의문이 남는다. 따라서 대화와 질문지 조사를 병행할 필요가 있다고 생각된다.

금속 산화물을 기반으로 한 이산화탄소 포집과 저장에 대한 최근 기술

오현영,라즈쿠마 파텔 한국막학회 2020 멤브레인 Vol.30 No.2

이산화탄소 포집 및 저장기술(CCS)은 인류발생적 요인에 의한 이산화탄소 배출 증가와 그로 인한 기후변화를 완화시킬 수 있는 기술 중 하나이다. 그 중, 매체 순환식 연소(chemical looping combustion, CLC)와 칼슘루핑(calcium looping) 기술은 현재 아민 스크러빙(amine scrubbing)을 대체할 수 있는 유망한 기술로 주목받고 있다. 두 방법 모두 금속 산화물을 이용한 연속적인 순환 사이클 반응에 의한 것이다. 전체적인 이산화탄소 포집 및 저장 성능의 향상을 위해서는 사이클을 거듭 하며 발생하는 소결(sintering)로 인한 안정성 저하 문제를 해결하고 금속 산화물의 구조 또한 최적화해야 한다. 금속 산화물 표면에 얇은 박막을 형성하는 것은 소결로 인한 손상을 막을 수 있는 방법이다. 이러한 박막 제조 기술로 잘 알려진 기술에는 화학기상증착법(chemical vapor deposition)과 원자층증착기술(atomic layer deposition)이 있다. 본 총설에서는 CVD, ALD 기술을 비롯하여 효과적인 반응 안정성 향상을 위한 안정제 첨가 방법, 금속 산화물 구조 개선에 대한 다양한 최근 기술들을 다루었다. CO2 capture and storage (CCS) is one of the promising technologies that can mitigate ever-growing emission of anthropogenic carbon dioxide and resultant climate change. Among them, chemical looping combustion (CLC) and calcium looping (CaL) are getting increasing attention recently as the prospective alternatives to the existing amine scrubbing. Both methods use metal oxides in the process and consist of cyclic reactions. Yet, due to their cyclic nature, they both need to resolve sintering-induced cyclic stability deterioration. Moreover, the structure of the metal oxides needs to be optimized to enhance the overall performance of CO2 capture and storage. Deposition of thin film coating on the metal oxide is another way to get rid of wear and tear during the sintering process. Chemical vapor deposition or atomic layer deposition are the well-known, established methods to form thin film membranes, which will be discussed in this review. Various effective recent developments on structural modification of metal oxide and incorporation of stabilizers for cyclic stability are also discussed.

「んです」の使用実態と特徴-日本語母語話者と韓国人日本語学習者の会話を中心に-

오현영 동북아시아문화학회 2023 동북아 문화연구 Vol.1 No.74

In this study, analyzed the tendency and characteristics of the use of ‘ndesu’ for the first face-to-face conversation between Japanese native speakers and Korean Japanese learners. The results of the analysis of the utterance of “ndesu” were divided into KF and JF, and the analysis of KM and JM was divided into male and female. The characteristics of the actual conversation were also described. The main results are summarized as follows. First, looking at the tendency of native Japanese speakers, both female native Japanese speakers and male native Japanese speakers showed a tendency to use “description”, “true questionnaire”, and “questionnaire”. Next, women and men, who were Korean learners of Japanese, used the most frequently after “explanation,” “true questioning,” followed by “conviction” and “teaching.” Both native Japanese speakers and Korean learners of Japanese had something in common with each other in terms of “explanation” and “truth and authenticity questions.” However, most Korean learners of Japanese were followed by “pushing” and “teaching” followed by “surprise” and “confirmation” among native speakers of Japanese. Next, looking at the difference between men and women, it was found that both native Japanese speakers and Korean learners had similar usage trends, but women used them more frequently. Finally, describe the characteristics that are not found in previous studies from actual conversation examples.As a characteristic of this, there were several expressions that strongly expressed disapproval in the “noda” of “pressing carefully.” If you continue to use the word “ndesu” in “ndesu” when you disagree with the other person, you may make an unpleasant impression on the other person may have an unpleasant impression. In addition, “teaching,” which was often used by Korean learners of Japanese and native speakers of Japanese, seemed to teach the other person's questions in detail. In particular, the words of “teaching” seemed to teach each other about each other's culture and things they didn't know.
