테크놀로지 교수내용지식(TPACK) 관점에서 설명 동영상의 멀티모달 표상전략 탐색

김예인,소효정 한국교육정보미디어학회 2024 교육정보미디어연구 Vol.30 No.3

본 연구는 최근 온라인 학습 플랫폼에서 빠르게 증가하고 있는 짧은 길이의 설명 동영상에 주목하여, 설명 동영상의 멀티모달 표상을 분석하고 설계전략을 탐색하고자 하였다. 이를 위해 TPACK 관점에서개발된 멀티모달 표상의 유형 및 목적에 관한 코딩 체계를 기반으로 EBS, Khan Academy, Udemy의 설명 동영상 20개를 멀티모달 내용분석 절차에 따라 분석하였다. 연구 결과, 멀티모달 표상의 유형별 사용 빈도는 전체적으로 주석이 51.78%로 가장 많이 사용되었으며 글쓰기 유형은 37.35%이고, 상대적으로 시각적 요소의 활용은 10.87%로 낮은 편이었다. 세부 설계 요소의 사용 빈도를 살펴보면 전반적으로 실시간으로 포인팅 주석을 활용하는 빈도가 가장 높았으며, 그다음으로 실시간 손글씨, 준비된 타이핑 글씨, 실시간 수학/과학 기호 순으로 높게 나타났다. 강조를 위한 실시간 주석 활용의 경향성은플랫폼과 주제 영역에 걸쳐 고르게 나타났다. 멀티모달 내용분석 결과를 기반으로 설명 동영상의 세가지 유형을 도출하고 설계적 고려점을 제시하였다. 본 연구는 설명 동영상에서 집중을 위한 실시간주석 및 글쓰기 이외의 멀티모달 요소의 사용 빈도가 그리 높지 않으며, 따라서 설명자가 보다 다양한 형태의 멀티모달 표상전략의 활용에 대한 지식을 습득하고 적용할 필요가 있음을 시사한다. 더불어, 본 연구는 그동안 암묵적 지식으로 간주되었던 설명 동영상의 멀티모달 표상전략을 외현화하고연구 방법을 확장하였다는 점에서 의의가 있다. This study aims to examine the multimodal representation strategies of explainer videos, which are rapidly increasing on online learning platforms. For this purpose, 20 explainer videos from EBS, Khan Academy, and Udemy were analyzed following a multimodal content analysis procedure based on a coding system developed from the TPACK perspective, identifying types and purposes of multimodal representations. The results showed that annotations were the most frequently used type of multimodal representation, accounting for 51.78% of the total, followed by writing at 37.35%, while the utilization of visual elements was relatively low at 10.87%. Among the specific design elements, the most frequently used was real-time pointing annotations, followed by real-time freehand writing, prepared typing text, and real-time math/science symbols. The trend of utilizing real-time annotations for emphasis was evenly distributed across platforms and subject areas. Based on the results of multimodal content analysis, three types of explainer videos were identified with design considerations. The findings suggest that the frequency of using multimodal elements other than real-time annotations and writing for emphasis is not very high, indicating the need for explainers to acquire and apply knowledge on the utilization of diverse forms of multimodal representation strategies. Additionally, this study is significant as it unpacks the multimodal representation strategies of explainer videos, which have been considered implicit knowledge, from the TPACK perspective and extends research methods.

This study was conducted to obtain basic information for the use of the ATP fluorescence detection method in consideration of the most common and frequent contamination situation that occurs in laboratories dealing with fire blight causing bacterium, Erwinia amylovora. ATP luminescence measurements (Relative Light Unit, RLU) were tested against these pathogen cells (CFU/cm2 ) which were artificially introduced on the disinfected surface of a bench floor of a biosafety cabinet (Class 2 Type A1), on a part of the disinfected surface of a lab experimental bench, on a part of the disinfected floor, and on a part of the disinfected floor of an acryl chamber for bioaerosol studies in a biosafety laboratory (BSL 2 class) using two different ATP bioluminometers. RLU values were not much increased with the bacterial cells from 2.15 × 102 /cm2 to 2.15 × 106 /cm2 . RLU values varied among the four different surfaces tested. RLU values measured from the same number of bacterial cells differed little between the two different ATP bioluminometers used for this study. RLU values obtained from bacterial cells higher than 2.15 × 107 /cm2 indicated the presence of bacterial contamination on the four different surfaces tested. The R2 values obtained based on the correlation data for the RLU values in response to different E. amylovora cell numbers (CFU/ cm2 ) on the surfaces of the four test spots ranged from 0.9827 to 0.9999. .

기수산 물벼룩 Diaphanosoma celebensis 에 대한 아세트아미노펜과 이부프로펜의 급성독성과 해독, 항산화 및 탈피 연관 유전자의 발현에 미치는 영향

Acetaminophen (ACT) and ibuprofen (IBU) are most frequently detected pharmaceuticals in aquatic ecosystem, and they can induce various harmful effects on aquatic biota. However, the toxicity of ACT and IBU on marine biota and their underlying toxic mechanisms are not well-understood. Thus, in this study, we investigated acute toxicity of ACT and IBU on the brackish water flea Diaphanosoma celebensis, and subsequently, transcriptional modulation of genes related to detoxification, antioxidant system, and ecdysteroid signaling pathway was analyzed. Acute toxicity test showed ACT and IBU have relatively less acute toxicity on D. celebensis (48-h LC50ACT: 120.72 mg/L and 48-h LC50IBU: 212.23 mg/L). After exposure to ACT, the expression of most detoxification-related genes was down-regulated, but the expression of cytochrome P450 (CYP) 360A8, glutathione S-transferase (GST) theta, and ATP-binding cassette (ABC) transporter B1 was significantly up-regulated following IBU exposure, which suggests that ACT and IBU might differently affect detoxification system of D. celebensis. However, the expression of most genes related to antioxidant system and ecdysteroid signaling pathway was significantly decreased following ACT and IBU exposure. These findings suggest that ACT and IBU may be metabolized by different mechanisms and have potential toxicity on redox homeostasis and reproductive process of marine zooplankton. 아세트아미노펜(acetaminophen, ACT)과 이부프로펜(ibuprofen, IBU)은 수생환경에서 발견되는 대표적인 의약품으로, 다양한 수생생물에서 생물독성영향을 나타내는 것으로 알려져 있으나 이들이 해양생물에 미치는 독성영향은 잘 알려져있지 않다. 이에 본 연구는 ACT 및 IBU가 기수산 물벼룩 Diaphanosoma celebensis에 미치는 급성독성영향 및 해독, 항산화, 탈피 연관 유전자의 발현에 미치는 영향을 조사하였다. 급성독성시험 결과, ACT 및 IBU는 D. celebensis에 상대적으로 낮은 급성독성영향을 나타냈다 (48-h LC50ACT: 120.72 mg/L 및 48-h LC50IBU: 212.23 mg/L). 해독효소 유전자의 발현은 ACT 노출 시 모두 유의하게 감소한 반면 IBU 노출 시 Cytochrome P450 (CYP) 360A8, glutathione S-transferease (GST) theta, 및 ATP-binding cassette (ABC) transporter B1 유전자의 발현이 증가하였으며, 이는 ACT 및 IBU가 해독 경로에 미치는 영향이 서로 다를 수 있음을 의미한다. 반면 ACT 및 IBU의 노출은 공통적으로 D. celebensis의 항산화 및 탈피 연관 유전자의 발현을 감소시키는 것으로 나타났다. 본 연구의 결과는, ACT 및 IBU가 서로 다른 작용기전을 통해 대사될 수 있지만, 공통적으로 해양 동물성플랑크톤의 산화환원 항상성과 생식경로에 잠재적인 독성영향을 나타낼 수 있음을 시사한다.

Fungal contaminant in the indoor air is one of risk factors that could damage valuable paper-based records preserved in libraries. In the process of monitoring airborne fungi at the Nara Repository, the National Archives, Seoul, Korea, three fungal strains, DUCC 16098, DUCC 17764, and DUCC17767 were isolated from the archive’s air samples. Fungal identification was performed based on the morphological characteristics and phylogenetic analysis of the internal transcribed spacer (ITS), the 28S LSU rDNA, and β-tubulin gene (BenA), and TEF1-α gene. These DUCC 16098, DUCC 17764 and DUCC17767 strains were identified as Clonostachys farinosa, Penicillium cosmopolitanum, and Cephalotrichum purpureofuscum. These species have not been recorded before in Korea. Information on these fungi will help the monitoring and management of airborne fungi in the archival facilities.

The purpose of this study was to identify the relationship between the relational loss and post-traumatic growth among college students, and how balanced time perspective and adaptive cognitive emotion regulation strategies mediate this relationship. For this, 261 Korean college students were asked to complete questionnaires measuring relational loss, balanced time perspective, adaptive cognitive emotion regulation strategies, and post-traumatic growth. The results show that first, the severity of distress from relational loss was positively correlated with the deviation of the balanced time perspective. The deviation of the balanced time perspective was negatively correlated with the adaptive cognitive emotion control strategies and the post-traumatic growth. Second, balanced time perspective, but not adaptive cognitive emotion regulation strategies, significantly mediated the relationship between the severity of distress and post-traumatic growth. Third, balanced time perspective and adaptive cognitive emotion regulation strategies in a serial order fully mediated the severity of distress and post-traumatic growth. Implications for counseling practice and further research are also discussed.
