실시간 온라인 화상 한국어 수업에서의 상호작용 -사회통합프로그램 수업을 중심으로-
최은지 ( Choi Eunji ) 겨레어문학회 2021 겨레어문학 Vol.67 No.-
본고에서는 실시간 온라인 화상 한국어 수업에서의 상호작용 양상을 분석하고 자 하였다. 이를 위해 본고에서는 3개의 한국어 교실에서 실시간 온라인 방식으로 진행된 한국어 수업 26차시를 녹화하고 이를 전사하여 분석하였다. 분석은 수업에서의 교사와 학습자의 발화량, 연습 활동과 의사소통 활동의 유형, 상호작용 활동의 조직 유형에 대해 이루어졌다. 본 연구의 분석 결과 실시간 화상 온라인 한국어 수업에서는 교사의 발화량이 전체의 80% 내외를 차지하는 것으로 나타났다. 분석 결과 온라인 수업에서 학습자의 발화량은 일반 수업에서보다 적었는데, 이는 학습자의 자유로운 발화를 독려하는 언어 사용 시간의 비중이 높지 않았기 때문이었다. 또한 언어 사용 시간에도 학습자의 주도적인 의사소통 활동이 많이 이루어지지 않고 있었으며 상호작용의 조직 방식 역시 단조로운 유형으로 나타났다. Interaction of Korean class on real-time online video is analyzed in this study. In this purpose, 26 times of Korean classes conducted on real-time online method in three Korean classrooms were recorded and transcribed and analyzed in this study. The analysis was conducted on the amount of utterance of teachers and learners in class, the type of practice and communication activities and the type of organization of interaction activities. It was found that the amount of teacher utterance accounted for around 80% of the total in Korean classes on real-time online video as a result of the analysis in this study. The learner’s speech amount in online classes was less than in general classes because the proportion of language use time encouraging learners to speak freely was not enough as a result of the analysis. Also, learners did not have many leading communication activities even during language use time and the organization of interaction was also in monotonous types.

Post-Use의 사용자조사를 위한 기초연구 : Post-Use의 정의와 사례조사를 중심으로
최은지(Choi Eunji),이건표(Lee Kunpyo) 한국디자인학회 2010 한국디자인학회 학술발표대회 논문집 Vol.2010 No.10
This study tries to understand, define, and categorize Post-Use as fundamental research of user research on Post-Use. Since user research has been mostly focused on tbe acquisition of product, and its usage so far, user research on Post-Use didn't get much attention, and were almost neglected. In order to figure out the potential of user research on Post-Use, the concept of Post-Use itself needs to be understood and well defined first of all. In order to define the concept of Post-Use, it is also required to look at life cycle of product, because it is the base that can be used in the definition of Post-Use. After understanding life cycle of product, and defining Post-Use, it can be largely classified into 3 categories: reuse, recycle, and remanufacture. Categories of reuse and remanufacture have its sub categories such as reuse by recognition, distribution, and repair, and remanufacture by component, and product itself. Based on these categories, case study was conducted. This study is helpful for understanding the concept of Post-Use, and expected to be utilized as a fundamental frame for conducting user study in the follow up research.

소포제 첨가에 따른 Trichoderma sp.의 cellulase 활성 변화
최은지 ( Eunji Choi ),김영숙 ( Yeong-suk Kim ),윤정희 ( Jeonghee Yun ) 한국목재공학회 2021 한국목재공학회 학술발표논문집 Vol.2021 No.2
Trichoderma sp. is a widely used fungal strain that produces lignocellulolytic enzymes. During the incubation in bioreactor, there are significant physical parameters such as temperature, pH and gas flow rate and they can affect enzyme production. The intense aeration and stirring in the process of bioreactor can cause the formation of foam. Foam can negatively affect cells and proteins and excessive foam on surface not only leads to reduction of oxygen transfer, but can also overflow the bioreactor and cause safety issues during operation. These problems can result in decreased process productivity, therefore antifoaming agents are crucial to preventing the formation of foam. In present study, Cellulase activity during incubation of Trichoderma sp. in lab scale bioreactor was monitored dependent on types of antifoaming agent. Endoglucanase(endo-1,4-β-d-glucanase EG, EC 3.2.1.4) and β-glucosidase(1,4-β-d-glucosidase, BGL, EC 3.2.1.21) activity were periodically measured. At the maximum enzyme activity, it was observed that Trichoderma sp. incubated with antifoaming agents increased EG and BGL activity by 4-fold and 3-fold, respectively after 15days of incubation. These results suggest that the addition of antifoaming agents is essential for incubation and may have significant effect on the increase in fungal growth and cellulase production.

A difference invertible Bloom filter(d-IBF) has been used to identify the difference of sets using two invertible Bloom filters. However, since decoding depends only on pure cells, the decoding performance is very low in case of memory less than a certain size. In this paper, we classify the types of decoding errors in d-IBF, and propose a new decoding method that improves the decoding performance. Simulation result shows that the proposed decoding method reduces the number of occurrences of each type causing decoding errors, which allows us to identify the difference of sets even in a smaller size of memory.

본 연구의 목적은 탈성매매 청소년이 탈성매매 이후 어떠한 삶을 살아가고 있는지 탐색함으로써 그들의 삶의 적응경험을 규명하고, 이를 통해 탈성매매 후 삶의 적응을 돕고 적응과정에 도움을 줄 수 있는 효율적인 개입방안을 밝히는 것이다. 이를 위해 청소년기 성매매를 경험하였지만 현재는 탈성매매 후 삶의 적응과정에 있는 후기 청소년 12명을 인터뷰하였으며, 변화의 과정을 근거이론 접근방법을 통해 분석하였다. 분석의 결과는 다음과 같다. 탈성매매 청소년의 삶의 적응과정에 인과적 조건으로는 ‘과거에 대한 후회와 죄책감’, ‘감추고 싶은 과거’로 나타났으며 중심현상으로는 ‘부끄러움 없는 떳떳한 삶을 살고 싶음’으로 나타났다. 이러한 중심현상을 가져오는 맥락적 조건으로는 ‘후유증’, ‘힘겨운 사회적응’, ‘끊임없는 낙인’, ‘두려운 앞날’이었으며, 작용/상호작용 전략을 중재하는 중재적 조건으로는 ‘사회적 지지체계 형성’으로 나타났다. 작용/상호작용 전략으로는 ‘성매매 재유입 유혹과 마주함’, ‘무너진 삶 속에서 희망을 싹 틔움’이며, 마지막 결과는 ‘성매매 재유입을 뿌리치기 위한 부단한 결심’, ‘다시 시작하는 내 인생’으로 나타났다. 선택코딩의 핵심범주는 ‘부끄러움을 버리고 떳떳한 삶으로 살아가기’로 나타났으며, 관계유형에 따라 ‘적응 포기형’, ‘적응 노력형’, ‘적응 성공형’으로 나타났다. 이러한 분석결과를 토대로 탈성매매 청소년이 사회 속에 재적응하여 자신의 삶을 잘 살 수 있는 방안과 연구를 위한 함의를 제언하였다. The purpose of this study is to investigate the adaptation experience of adolescents' life after de-prostitution by exploring their lives. Also, it is to identify effective intervention methods that enable them to adapt to life after de-prostitution and give them help in the adaptation process. For this purpose, 12 late adolescents, who experienced prostitution during adolescence but are currently in the process of adaptation to life after de-prostitution, were interviewed. The process of change that interviewees went through was analyzed through the grounded theory approach method. The results of the analysis are as follows. The causal conditions for the process in which the adolescent in de-prostitution adapted to the life were ‘regret and guilt for the past’ and ‘the past that I want to hide’. The central phenomenon that ‘I want to proudly live without shame’ was found. Contextual conditions such as ‘aftermath’, ‘difficult social adjustment’, ‘continuous stigma’, and ‘fearful future’ caused the central phenomenon. It showed that interventional conditions mediating action/interaction strategies were to 'form social support system’. Action/interaction strategies were to ‘encounter temptation to re-enter prostitution’, and ‘start to have hope in a shattered life’. The final result showed that there were ‘ceaseless decision not to re-engage in prostitution’ and ‘re-starting my life’. The key category of selective coding was ‘to be confident and lead a blameless life’. According to the relationship type, ‘adaptive abandonment type’, ‘adaptive effort type’, ‘adaptive success type’ were found. Based on the results of this analysis, this study suggested the implications for the future study, and ways that adolescents in de-prostitution re-adapt to the society and to live their own lives well.
