        중간 강의평가에 대한 온·오프라인 수업 비교분석

        전보라 ( Jeon¸ Bora ),류상현 ( Ryu¸ Sanghyeon ),구경희 ( Ku¸ Kyunghee ) 인하대학교 교육연구소 2021 교육문화연구 Vol.27 No.4

        본 연구는 COVID-19로 인한 대학 온라인 수업의 활성화에 따라 학생들이 경험한 온라인 수업과 오프라인 수업에 대한 요구를 확인하고, 수업 유형에 따른 수업 개선방안 및 향후 수업의 방향을 제시하는데 그 목적이 있다. 이를 위해 부산광역시 소재 A대학의 2021학년도 1학기에 개설한 454개 과목에 대한 중간 강의평가 22,380건 중 오프라인 수업 107개(6,747건), 온라인 수업 170개(9,412건)를 분석대상으로 하였다. 자료분석 방법은 5점 리커트(Likert) 척도의 9개 문항과 복수응답 가능 유형 1문항에 대해 빈도분석 및 기술통계분석을 실시하였으며, 서술형 주관식 문항으로 수집된 질적 데이터는 반복적 비교분석법을 활용하였다. 연구결과를 통해 문항별, 영역별, 교과구분별 중간 강의평가에서 전반적으로 오프라인 수업의 평점이 높게 나타남을 확인할 수 있었다. 또한 오프라인 수업의 긍정요인은 원활한 상호작용, 다양한 교수법의 활용, 학습 참여 촉진 및 동기부여로, 부정요인은 수업환경에 대한 불만족, 수업의 일회성으로 나타났다. 아울러 온라인 수업의 긍정요인은 반복학습 가능, 다양한 자원 활용, 부정요인은 불안정한 온라인 학습 환경, 수업 콘텐츠의 질 저하, 수업 집중도 저하로 나타났다. 분석한 내용을 바탕으로 수업 유형별 부정요인을 감소할 수 있도록 수업설계 시 긍정요인을 반영한 보완책을 마련해야 하며, 온라인 수업의 비중이 높아지는 만큼 제도적 차원, 교수자 차원에서 수업의 질 관리를 위한 노력이 지속적으로 요구된다. This study aimed to identify the needs of students in online and offline classes following the activation of online education at universities due to COVID-19, and to suggest ways of improving classes for each type and future directions of classes. Altogether, 107 offline classes (6,747 cases) and 170 online classes (9,412 cases) were analyzed based on 22,380 mid-semester evaluations in 454 subjects in the first semester of 2021 at A University in Busan. Frequency analysis and descriptive statistical analysis were performed on nine questions scored on a 5-point Likert scale and one multiple choice question. Qualitative data collected through an essay question were analyzed using iterative comparative analysis. The results confirmed that offline classes generally had high ratings in the mid-semester evaluations by question, area, and curriculum classification. Also, the positive factors of offline classes were shown to be effective interaction, use of a variety of teaching methods, promoting learning participation, and motivation. The negatives were dissatisfaction with the class environment and non-repeating classes. On the other hand, the positive factors of online classes were the possibility of repetitive learning and utilizing various resources, while the negative factors were unstable online learning environment, low quality of online class content, and poor concentration. To reduce the negative factors for each class type, countermeasures reflecting the positives factors should be prepared when designing classes. Also, as the proportion of online classes increases, continuing efforts to manage the quality of classes at the institutional and professors levels are needed.

        Sylvia Plath’s Snakecharmer and William Wordsworth’s Self Portrait: Hope and Aspiration to be a Poet, Growth of a Poet’s Mind

        임보라 ( Im¸ Bora ) 한국현대영어영문학회 2021 현대영어영문학 Vol.65 No.1

        Sylvia Plath was afflicted by the fear of death. Thus she desperately needed a place where she could be free from it and create new things like a god; the place was her own world of poetry. Controlling and sublimating her fear of death and the reality Plath grew the poetic mind and became a poet. On the other hand, Wordsworth's poetic mind was formed by the poet's interrelation with nature. Nature was Wordsworth's loving mother; young and old Wordsworth was solaced by the power of nature. It was also a stern teacher to Wordsworth. Wordsworth's love of nature led him to love human including himself. Wordsworth considered that “to love” is synonymous with “to know,” and thus the poet's love of nature made him learn and know of human nature fully. In this article I would like to read Plath's poems “Getting There,” “Snakecharmer,” and “The Lady and the Earthenware Head” etc. along with Wordsworth's The Prelude to examine the two poets' artistic aspiration and growth of their poetic mind.

        웹툰을 활용한 여성결혼이민자 대상 한국어 거절 화행 수업 방안 연구 -<며느라기>를 활용한 사례를 중심으로-

        이보라 ( Lee¸ Bora ) 국제한국어교육학회 2021 한국어 교육 Vol.32 No.4

        This study aims to propose a method for teaching married female immigrants the Korean refusal speech acts by using “Webtoons”. This study reviewed the Korean rejection strategy types proposed through previous studies and discussed the usefulness of webtoons in Korean language education. Based on that content, this paper designs a class on Korean refusal speech acts by using < Myeo-Neu-ra-gi > and applied it to Korean language classes. Educational implications were derived by analyzing the results of a class satisfaction survey for learners and institutional personnel. This study explored the possibility of using webtoons in the education of Korean refusal speech acts for female married immigrants and suggested pedagogic implications through class design and application.

        Poetic Elaborations in the Age of Romanticism: Contemporary Poetry’s Engagement with London Daily Press

        ( Im¸ Bora ) 한국현대영어영문학회 2021 현대영어영문학 Vol.65 No.3

        It is important to explore the British literature in the Romantic era, while appreciating its close relationship with the daily press and periodical publications. This paper aims to examine the interrelationship between the Romantic literature - especially the genre of verse - and daily press, which was published in London at that time. In this paper I would like to focus on the conservative and patriotic language shown in three publications issued in London, the British Critic, the Sun and the True Briton. Based upon the discussions about the language of the three publications, the British Critic, the Sun and the True Briton, I would like to explore contemporary poetry’s fruitful sharing of patriotic sentiments with those journalistic organs. In doing so, I will read James Thomson’s important verse, which is titled “Rule, Britannia” for the better understanding of British Romanticism. This paper treats the conservative tones of “Rule, Britannia” and the journalistic publications mentioned above. (Jeonbuk National University)

        중·장년층을 위한 OTT 서비스 인터페이스 사용성 연구 - 아이트래킹과 사후적 think-aloud 기법을 활용한 -

        김보라 ( Kim¸ Bo Ra ),연명흠 ( Yeoun¸ Myeong-heum ) 디자인융복합학회(구.한국인포디자인학회) 2021 디자인융복합연구 Vol.20 No.5

        OTT 서비스의 부상으로 기존 TV 시장이 지각 변동을 일으키고 있으나, 중·장년층은 이러한 변화에서 소외되어 있다. 2019년 기준 NETFLIX는 4%, WAVVE는 5%만이 50대 이상 사용자이다. 이를 개선하고자 본 연구는 중·장년층의 OTT 서비스 사용성 개선을 위해 진행되었다. 선행연구 조사와 인터페이스 분석을 통해 시각적 피드백, Autoplay(자동재생), 검색방식이라는 3가지 연구문제를 도출하였고, 이를 알아보기 위해 중·장년층과 청년층에게 동일한 태스크를 제공하여 실험하였다. 실험을 통해 중·장년층에게 특수하게 발생하는 문제 상황에 대한 다음과 같은 개선방안을 도출할 수 있었다. 우선 시각적 피드백에서는 대비보다 일관성 있는 디자인이 더 중요하다는 점과, 중·장년층의 멘탈모델에 부합하는 아이콘을 사용해야 한다는 점, Autoplay에서는 중·장년층이 느끼기에 적절한 시간을 발견하여야 한다는 점, 검색 상황에서는 멀티태스킹을 도울 수 있는 검색 인터페이스를 디자인해야 한다는 점을 발견하였다. 본 연구는 특히 아이트래커를 이용한 사후적 think-aloud 기법을 사용함으로써 보다 실증적이고 구체적인 데이터를 얻어낼 수 있었다는 점에서 의의가 있다고 할 것이다. The rise of OTT service is causing a seismic change in the existing TV market, but the middle-aged and elderly people are marginalized from these changes. As of 2019, only 4% of NETFLIX and 5% of WAVVE are users in their 50s or older. This study was conducted to improve the usability of OTT service among middle-aged and elderly people. Through interface analysis, three research themes were derived: visual feedback, autoplay, and search method. To find out, the same task was provided to middle-aged, elderly and young people and the experiment was conducted. Through the experiment, we were able to discover the following problematic situations and inconveniences that are specially issued to middle-aged and elderly people. First, in visual feedback, we found that consistent design is more important than contrast, that icons that match the mental model of middle-aged people should be used, in Autoplay, that middle-aged people need to find an appropriate time to feel. In search situations we found that we need to design a search interface that can help the middle-aged and elderly people to multitask. This study is particularly meaningful in that it was able to obtain more empirical and concrete data by using the eye-tracking retrospective think-aloud technique.

      • The Catalytic Reduction Performance of Nitrogen Oxides over the Vanadium based Catalysts : Effect of Colloidal Silica and Glass Fiber

        Bora Jeong(정보라),Myeung-jin Lee(이명진),Bora Ye(예보라),Seung-Yeop Chun(전승엽),Taewook Kim(김태욱),Hong-Dae Kim(김홍대) 한국에너지기후변화학회 2021 한국에너지기후변화학회 학술대회 Vol.2021 No.5

        Regulation of air pollution (e.g., EURO 6, TIER 3) has been strengthened in many jurisdictions due to the occurrence of problems such as particulate matter (PM). At present, selective catalytic reduction (SCR) is the most effective method to control NOX emissions. Industrial V2O5-WO3/TiO2 catalysts (usually containing 0.5–3wt% V2O5 and 5–10wt% WO3) exhibit high de-NOX efficiency, and excellent resistance to sulfur (SO2) and H2O. Nevertheless, they also have several disadvantages such as high and narrow effective temperature range(300–400°C), and a tendency to oxidize SO2 to SO3. Therefore, SCR catalysts with high de-NOX efficiency at lower operating temperatures are required in order to obtain economic benefits and reduced energy consumption. Typically, silica has a good candidate to improve catalytic properties such as led to generation acid site, specific surface area, thermal stability. In this reason, enhanced the SCR catalyst property by using colloidal silica and glass fiber. The aim of this work, we confirmed the effect of silica on the chemi-physical properties and de-NO<sub>X</sub> efficiency of vanadium based catalyst. These synthesized catalysts were analyzed by BET, TPD, FT-IR and catalytic performances using fixed-bed reactor in the range of 200-450°C.

        Hesperidin Suppresses Melanosome Transport by Blocking the Interaction of Rab27A-Melanophilin

        ( Bora Kim ),( Jee Young Lee ),( Ha Yeon Lee ),( Ky Youb Nam ),( Jong Il Park ),( Su Min Lee ),( Jin Eun Kim ),( Joo Dong Lee ),( Jae Sung Hwang ) 한국응용약물학회 2013 Biomolecules & Therapeutics(구 응용약물학회지) Vol.21 No.5

        We investigated the inhibitory effects of hesperidin on melanogenesis. To fi nd melanosome transport inhibitor from natural products, we collected the structural information of natural products from Korea Food and Drug Administration (KFDA) and performed pharmacophore-based in silico screening for Rab27A and melanophilin (MLPH). Hesperidin did not inhibit melanin production in B16F10 murine melanoma cells stimulated with α-melanocyte stimulating hormone (α-MSH), and also did not affect the catalytic activity of tyrosinase. But, hesperidin inhibited melanosome transport in melanocyte and showed skin lightening effect in pigmented reconstructed epidermis model. Therefore, we suggest that hesperidin is a useful inhibitor of melanosome transport and it might be applied to whitening agent.
