ABSTRACT
Cartoons have become one of the social artifacts used to express ideas in the world. These ideas often represent the views, perspectives, behaviors and the core patterns of human life. This is so because cartoons are designed to contain social events or activities, typically combining satiric and hyperbolic features to reflect various social mores that affect all facets of society. Such a development has demonstrated a genuine role of cartoons in providing knowledge to specific human activity. this esoteric role of cartoons in edifying human society has led to the development of several studies of which the current study is not exceptional. By this, the nature of the current study is to examine how cartoons have been used as a social model to communicate COVID-19 messages in Ghana.The study employs content analysis in its development and applies (Kress, van Leeuwen's (1996) Reading images: the grammar of visual design. Routledge, London;Kress, van Leeuwen's (2006) Reading images: the grammar of visual design. Routledge, London) Grammar of Visual Design theory as the core theoretical framework. The data for the study are taken from the canon of ‘Tilapia Da Cartoonist' of Media General Group. In all, seven different forms of cartoons were purposively sampled and used for the study. The study later revealed that cartoons were used to signal hope, caution, relief, warning and anxiety on the dangers associated with COVID-19 pandemic. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
ABSTRACT
As the world is still recovering from the detrimental effects of the COVID-19 pandemic, one key aspect of the pandemic era were the global efforts for containment, case tracking and several other factors. While the scientific and governmental initiatives were largely successful and effective, a notable surge was observed in contributions from individuals and programming communities that developed their own software for COVID-19 by using data retrieval and analysis along with visualization methodologies. To achieve their goals, they turned their attention to knowledge exchange portals and asked questions regarding technological queries. In this paper, we present a collective platform that retrieves such questions from a well-known Q&A portal and visualizes the contained information. This platform serves as a useful tool for assessing programming and technological interest in COVID-19 related software development efforts while also promoting the open science principles. © 2022 ACM.
ABSTRACT
Aerosol transmission has played a leading role in COVID-19 pandemic. However, there is still a poor understanding about how it is transmitted. This work was designed to study the exhaled breath flow dynamics and transmission risks under different exhaling modes. Using an infrared photography device, exhaled flow characteristics of different breathing activities, such as deep breathing, dry coughing, and laughing, together with the roles of mouth and nose were characterized by imaging CO2 flow morphologies. Both mouth and nose played an important role in the disease transmission though in the downward direction for the nose. In contrast to the trajectory commonly modeled, the exhaled airflows appeared with turbulent entrainments and obvious irregular movements, particularly the exhalations involving mouth were directed horizontal and had a higher propagation capacity and transmission risk. While the cumulative risk was high for deep breathing, those transient ones from dry coughing, yawning, and laughing were also shown to be significant. Various protective measures including masks, canteen table shields, and wearable devices were visually demonstrated to be effective for altering the exhaled flow directions. This work is useful to understanding the risk of aerosol infection and guiding the formulation of its prevention and control strategies. Experimental data also provide important information for refining model boundary conditions.

Objective: Many studies have suggested herbal medicines as alternatives or adjuvants to modern drugs for COVID-19. Their scientometric analyses can provide a scientific overview of this topic. Materials and methods: Web of Science (WOS) and Scopus were searched for articles on the use of herbal medicines in COVID-19 published until 26 October 2020. Collected data were analyzed for document type, subject area, top journal, citation number, and authors' collaboration network using VOSviewer 1.6.15, ScientoPy 2.0.3, Gephi 0.9.2, and SPSS 15 statistical tools. Results: After screening the 3185 retrieved records, 378 and 849 records, respectively from WOS and Scopus, remained for quantity analysis. Original and review articles were the two main types of papers in both databases. Top subject areas were drug and medicine, respectively in the WOS and Scopus databases. The top three productive countries in the field were China, the US, and India. The most cited article was a practice guideline in both databases. "Journal of Biomolecular Structure Dynamics" in WOS and "Chinese Traditional and Herbal Drugs" in Scopus were the top journals. Top keywords included "COVID-19â³ and "Traditional Chinese Medicine". US authors had the highest collaboration with other authors. Conclusions: The current study provides a snapshot of the quantity and characteristics of published scholarly documents in recent months in the intersection of herbal medicines and COVID-19. Our findings help scientists to find the existing gaps, identify the active authors and scientific institutes to collaborate with and use their experience to produce new knowledge in the future.
ABSTRACT
The purpose of this study was to explore strategies for distributing online content of dance post COVID-19 in Korea. And specially to discuss the distribution strategies of online performances through videoization of dance performances and OTT (over-the-top) streaming: (1) Methods: For this purpose, a survey was conducted on the distribution strategy of dance online contents for a total of 100 practitioners such as dance field, video contents, and art management. A total 91 sample were used except for defective questionnaires, and Vavra (1997)'s modified important performance analysis was conducted; (2) Results: The results of the matrix through the modified IPA analysis are as follows: first, the first quadrant included 'quality of dance performance', 'platform for OTT streaming', and 'promotion for potential audience development'. This means that both explicit and intrinsic importance are high, and it is an important execution factor that has a positive effect on the satisfaction of the online contents of dance only if it is met. Second, the second quadrant included 'brand awareness of choreographer or dance company', 'creative composition and choreography', and 'fee and price criteria'. This is a case of low explicit importance but high intrinsic importance, and these factors are attractive attributes that affect the satisfaction of dance online contents, although consumers do not expect it to be important. Third, the third quadrant included 'new formats and curation', 'convergence technology (AR, VR, 3D, etc.) for the field sense', and 'online audience service (communication, membership, etc.)'. This means that both explicit and intrinsic importance are low, and if these factors are met, it can have a positive effect on the satisfaction of viewing of dance online contents. However, it does not have a negative effect even if it is not met. Fourth, in the fourth quadrant, 'production and editing competency', 'quality of videos and sounds', 'copyright of performance creation', and 'fandom and audience management' was included. This is an essential attribute in the distribution strategy of dance online contents because it has high explicit importance and low intrinsic importance, and it can have a negative impact on satisfaction when these factors are not met.
