동영상을 활용한 음악과 마이크로티칭에 대한 예비 초등교사의 성찰

최미영 미래음악교육학회 2023 미래음악교육연구 Vol.8 No.1

The purpose of this study was to investigate what and how preservice elementary school teachers reflect on after watching their own video-taped microteaching. Fifty-one preservice teachers wrote reflection journals two times, right after their microteaching and after watching their video-taped microteaching at home. Preservice teachers' pre-watching and post-watching reflection journals, and transcripts of the meeting between instructor and preservice teachers after watching video-taped microteaching were qualitatively analyzed. As a result, there were no major changes in the content of preservice teachers' pre-watching and post-watching reflection journals but they could reflect on their music teaching in detail after watching their video-taped microteaching. The video-taped microteaching allowed them to identify the causes of difficulties like time management and students' level setting, and find ways to improve their teaching practice. Also, they became aware of problems to be unrecognized during microteaching such as presentation-styled teaching and the necessity of appropriate, diverse teaching materials through video observation. Preservice teachers paid the attention to their appearance on the screen while watching the video. They recognized that video was a springboard to reflect on their teaching, and helped them to look into it objectively. 본 연구는 예비 초등교사들이 음악과 마이크로티칭 녹화 동영상을 보며 수업에서 어떤 점 에 초점을 두고 무엇을 성찰하며 어떻게 활용하는지 예비교사들의 수업 성찰에 대해 분석하 였다. 이를 위해 예비교사 51명이 마이크로티칭 직후와 동영상 관찰 후에 각각 작성한 자기 성찰지와 동영상 관찰 후 실시한 협의내용이 분석되었다. 연구 결과, 마이크로티칭 시연 직후 와 동영상 관찰 후 예비교사들이 작성한 성찰지 내용의 큰 변화는 없었지만, 구체적인 성찰 을 하였음을 알 수 있었다. 예비교사들은 동영상 관찰을 통해 수업 시간 운용과 학생 수준 설정의 어려움에 대한 원인과 개선 방안을 모색하였고, 수업 시연에서 미처 인지하지 못했던 점으로 발표식 수업 진행과 수업 자료의 적절성 및 다양성을 발견하였다. 그들은 동영상을 보면서 화면 속 자신의 모습에 가장 많이 주목하였으며, 동영상이 자신의 수업 성찰을 위한 발판이며 객관적인 시각에서 자신의 수업을 보는 데 도움을 준다고 인식하였다.

N4SSB 단백질의 C-말단기의 7개의 아미노산이 N4SSB 단백질의 in vivo 활성에 미치는 영향

최미영,Choi, Mieyoung 한국미생물학회 1998 미생물학회지 Vol.34 No.4

Bacteriophage N4, a lytic phage specific for Esherichia coli K12 strain encodes single-stranded DNA-binding protein, N4SSB (bacteriophage N4-coded single-stranded DNA-binding protein). N4SSB protein is originally identified as a protein required for N4 DNA replication. N4SSB protein is also required for N4 late transcription, which is catalyzed by E. coli ${\sigma}^{70}$ RNA polymerase. N4 late transcription does not occur until N4SSB protein is synthesized. Recently it is reported that N4SSB protein is essential for N4 DNA recombination. Therefore N 4SSB protein is a multifunctional protein required for N4 DNA replication, late transcription, and N4 DNA recombination. In this study, a variety of mutant N4SSB proteins containing internal deletions or substitutions were constructed to define and characterize domains important for N4 DNA replication, late transcription, and N4 DNA recombination. Test for the ill vivo activity of these mutant N4SSBs for N4 DNA replication, late transcription, and N4 DNA recombination was examined. The results suggest that C-terminal 7 amino acid residues are important for the activity of N4SSB. Three lysine residues, which are contained in this region play important roles on N4SSB activity. Esherichia coli(E. coli) K12 균주를 숙주세포로 삼는 박테리오파아지인 N4는 single-stranded DNA에 결합하는 단백질인 N4SSB(bacteriophage N4-coded single-stranded DNA-binding protein) 단백질을 만든다. N4SSB 단백질은 N4 DNA replication 뿐만 아니라 late transcription과 N4 DNA recombination에도 필요한 여러 가지 기능을 가진 단백질이다. N4 late transcription은 숙주세포인 E. coli의 $E{\sigma}^{70}$ RNA polymerase에 의해서 수행이 되나 N4SSB 단백질을 반드시 필요로 하기 때문에 N4SSB 단백질이 생성될 때까지는 N4 late promoter로부터 RNA 합성이 일어나지 않는다. 본 연구에서는 N4SSB의 N4 DNA replication과 late transcription, 그리고 N4 DNA recombination에 필요한 영역(domain)을 알아내기 위해서 여러 가지 돌연변이형 N4SSB 단백질을 만들어 N4 DNA replication과 late transcription, 그리고 N4 DNA recombination의 3가지 작용에 대한 in vivo 활성을 조사 분석하였다. 그 결과 N4SSB 단백질의 C-말단기에 있는 7개의 아미노산이 N4SSB 단백질의 활성에 중요하다는 것을 알 수 있었다. 특히 C-말단기의 7개의 아미노산에는 세 개의 lysine이 포함되어 있는데 이 lysine이 N4SSB 단백질의 활성에 중요한 역할을 한다는 것이 제시되었다.

본 연구의 목적은 옴니채널 환경에 익숙한 20대 여대생 60명의 쇼핑 다이어리를 분석하여 패션 소비자의 쇼핑패턴 유형별 정보탐색 행동 및 구매과정과 구매 후 정보공유로 이어지는 일련의 구매여정을 살펴봄으로써 변화하는 패션유통환경에서 실무적으로 대응할 수 있는 시사점을 제안하는 것이다. 사전설문 결과 응답자들은 패션및 쇼핑 관여가 높고 SNS 활동에 대한 관여 또한 높은 디지털 소비자 집단으로 나타났다. 이들은 구매의지가없더라도 항상 모바일을 이용한 다양한 탐색활동을 통해 쇼핑에 관한 관심을 표출하고 있었다. 실증적 연구를통해 밝혀진 결과는 다음과 같다. 첫째, 응답자들의 쇼핑패턴은 정보탐색과 구매채널에 따라 8가지로 유형화되었다. 모바일 쇼퍼의 비중이 가장 높았지만, 전통적인 오프라인 채널을 이용하는 오프라인 쇼퍼도 포함되었다. 또한, 쇼루밍 쇼퍼와 역쇼루밍 쇼퍼 뿐 아니라 온·오프라인 채널 경계 없이 패션정보를 습득하고 구매하는 옴니채널 쇼퍼들이 세분화되어 나타났다. 둘째, 지속적인 정보탐색뿐 아니라 구매결정 단계에서 외적정보탐색에 의한 정보획득이 활발히 이루어지고 있었다. 셋째, 주의 및 흥미 단계에서도 필요한 브랜드나 제품에 대한 정보탐색을 위해 키워드 검색과 쇼핑몰 및 블로그 게시판의 리뷰와 후기 등을 활용하고 있었다. 넷째, 구매고려 및 비교/평가단계에서 매장 내 POP와 VMD 외에도 모바일을 통한 온라인 정보를 활발히 이용하고 있었다. 다섯째, 구매 결정에의 영향은 전통적인 매체 광고보다 온라인 네트워크 채널이 중요하게 작용하였다. 여섯째, 구매 후뿐 아니라 구매단계에서도 상품과 서비스의 사용 또는 이용 경험을 공유하고 있었다. 이때 모바일은 쇼핑 과정중 매장 쇼핑환경과 소비경험을 유기적으로 결합시킴으로서 소통의 장과 경험의 폭을 확장시키는데 활용되었다. 끝으로 본 연구가 패션 기업의 온·오프라인 통합채널 운영전략 및 옴니채널 서비스 개발을 위한 기초자료로활용될 수 있기를 바란다. The purpose of this study is to investigate the information search behaviors and purchase process of shopping patterns in the entire purchase journey by analyzing the shopping diary of 60 female college students in their 20s who are familiar with the omni-channel environment. The survey results showed that respondents were a digital consumer group with high involvement in fashion and shopping and social networking services. They were always expressing interest in shopping through a variety of mobile search activities, even if they had no intention of buying. The results of this empirical study can be summarized as follows: First, the respondents’ shopping patterns were categorized into eight types according to information search and purchase channel. Mobile shoppers accounted for the largest share, but offline shoppers using traditional offline channels were also included. In addition to showrooming shoppers and reverse-showrooming shoppers, Omni-channel shoppers using a variety of online and offline channels had been segmented. Second, on-going information search and information acquisition through external information search at the purchase decision stage were actively performed. Third, at the attention and interest stage, they showed an active attitude by searching keywords and reviewing shopping malls and blog boards to search for necessary brands or products. Fourth, the mobile was actively used without any on-offline boundary in the consideration and evaluation stage. Fifth, online network channels were more significant than traditional media advertisements at the stage of decision making. Sixth, they were sharing the experience of using goods and services not only after purchase but also at purchase stage. At this time, mobile was used to expand the field of communication and experience by combining the shopping environment and consumer experience in the shopping process. Lastly, it is hoped that this study can be used as basic data for developing the integrated channels strategy and omni-channel service of fashion companies.

The purpose of this study is to empirically test the effect of community social capital on theelderly's subjective quality of life by mediating sense of depression. For an empirical study,structural equation model and mediating regression model were applied to the final 261questionnaire survey data collected in Cheongju City. The result shows that among 4 socialcapital variables, only community attachment and community organization participation havesignificant influence on sense of depression and quality of life. They appear to affect the qualityof life indirectly as well as directly. On the other hand, there is no significant influence ofneighboring and neighbor trust on mediating and dependent variables. As implication, this studysuggests activation of the elderly's community organization, its mobilization for tacklingcommunity problems, and policy intervention for residential stabilization in the long run. 본 연구의 목적은 노인의 주관적 삶의 질에 미치는 지역사회 사회자본의 영향을 우울감을 매개로 하여 실증적으로 검증하는 것이다. 실증분석을 위해 청주지역 60세 이상 노인 261명의 설문조사결과를 최종적으로 활용하였고, 구조방정식모형과 매개회귀모형을 적용하여분석을 수행하였다. 연구결과, 지역사회 사회자본을 구성하는 변수들 중 지역사회 애착과 주민조직 참여가 우울감을 매개로 삶의 질에 간접적으로 영향을 미칠 뿐만 아니라 삶의 질에직접적인 영향을 미침으로써 노인의 정신건강과 삶의 질 향상을 위한 정책개입의 중요한 초점이 될 수 있음을 보여주었다. 이웃유대와 이웃신뢰는 우울감과 삶의 질에 유의미한 영향을 미치지 않은 것으로 나타났다. 정책적 시사점으로 노인의 지역사회 주민조직 참여의 활성화, 지역사회 문제해결을 위한 노인 조직의 활용, 그리고 장기적 관점에서 주거안정성의확보를 제시하였다.

유황성분 이용한 피부관리가 청소년 여드름 피부에 미치는 영향

최미영,임미혜 대전대학교 기초과학연구소 2014 自然科學 Vol.25 No.-

The purpose of this study was to determine potential effects of a skin care program - including home skin care products containing sulfur as well as skincar using contour mask- upon acne skin of adolescence. In order to achieve the purpose, total 18 teenagers residing in Boryeong city (Chungnam province, Korea) were asked to participate in an experiment, and were subdivided equally (6 subjects respectively) into three groups of subjects: Negative control was asked to just wash their face twice a day (in the morning and before going to bed) for about 4 weeks. Positive control was asked to practice skin care at home with aloe gel and sulfuric cream. And experimental group was asked to participate in a skin care program every 3 days along with skin care at home. Then, this study employed Derma vision(Optobiomed, Korea) to measure skin conditions of these 3 groups for 4 weeks (before experiment and every 3 days from baseline onward). As a result, it was found that negative control (just washing face) had no indication of significantly fewer skin pores than before, but positive control (just practicing skin care at home) had indications of little fewer skin pores than before, and care program group (joining a acne skin care program along with skin care at home) had indications of significantly fewer skin pores than before. In addition, it was found that negative control had no indication of significant fewer wrinkles than before, but positive control had indications of most significantly fewer wrinkles than before, and care program group showed significantly fewer wrinkles than before. However, it was found that only positive control (practicing skin care at home) showed favorable turns in the severity of erythema. Based on the above experiment, it was found that skin care program in combination with home skin care and contour mask was effective in reducing the number of skin pores, narrowing the area of wrinkles and improving melanin pigmentation. On the other hand, it was found that practice of skin care at home contributed significantly to alleviation of erythema, but skin care program in combination with home skin care contributed somewhat less to alleviation of erythema than expected. It is concluded that a combination of home skin care and acne skin care program (including sulfur as main ingredients) will be more effective in acne skin care. Ultimately, this study seeks to provide useful materials for development of manuals available at skin care clinics that deal with acne skin care.
