Published: December 2022

Indonesia's coffee production will reach 774.6 thousand tons in 2021, an increase of 2.75% from 2020, which was 753.9 thousand tons, and is the highest in the last decade and is expected to increase threefold in 2050. Hence, the evaluating environmental performance of the coffee agroindustry is essential if it is to become a more sustainable agroindustry. This paper aims to assess environmental performance (energy footprint, water footprint, and carbon footprint) in Gayo Arabica coffee green bean production with different agro-industry models. The method to evaluate environmental performance that can be used to identify indications of sustainability is Life Cycle Assessment (LCA) Method. The study was conducted on coffee production and exporter cooperatives in Central Aceh. Primary data were obtained through interviews with farmers, collectors, huller owners, and cooperative administrators. Secondary data comes from cooperative reports. The LCA study is described in two product systems, the model of 2015 and the model of 2016. The LCA model of 2015 is based on the green bean production system carried out in 2015 which includes water treatment, pulping, collecting, drying, hulling, finishing, and transportation. The LCA model of 2016 is based on the green bean production system carried out in 2016 until now which includes sub-processes for water treatment, pulping, collecting 1, hulling, collecting 2, finishing, and transportation. The results show that the energy footprint of the 2016 model (2.5128 MJ per f.u) is greater than that of the 2015 model (1.2336 MJ per f.u), the water footprint of the 2015 model is the same as the water footprint of the 2016 model product system, namely 0. 0086 m3 per f.u., and the carbon footprint of the 2016 model (1.93 kg CO2-eq per f.u) is greater than that of the 2015 model (1.48 kg CO2-eq per f.u). The cooperative initiative (in the model of 2016) is for the purpose of process improvement but cannot reduce carbon emissions. To reduce emissions from the use of fossil fuels, it is necessary to optimize land transportation routes and energy efficiency.

Published: December 2022

Prevalensi wanita dengan diagnosis Diabetes Mellitus (DM) meningkat sepanjang tahunnya termasuk dalam kehamilan. Kami laporkan kasus seorang wanita 36 tahun dengan persalinan anak pertama yang dikonsultasikan dengan peningkatan gula darah sesudah persalinan. Dari hasil anamnesa dan pemeriksaan fisik tidak didapatkan riwayat DM pada pasien dan keluarga yang dapat menjadi penyebab keterlambatan diagnosis DM pada kehamilan. Anamnesis, observasi dan hasil pemeriksaan laboratorium mengindikasikan potensi DM yang dimulai sebelum kehamilan namun tidak dikonfirmasi melalui skrining pemeriksaan gula darah pada kehamilan. Bayi yang dilahirkan mempunyai berat badan normal namun sempat mengalami hipoglikemia. Pasien diberikan terapi injeksi insulin basal dimulai pada dosis 6 iu dan dinaikkan bertahap menjadi 8 iu dan 10 iu, sesuai dengan hasil evaluasi hingga tujuan terapi tercapai. Kasus ini menunjukkan pentingnya penggalian riwayat dengan teliti dan skrining DM dalam kehamilan pada mereka yang berisiko untuk mencegah komplikasi pada janin maupun ibu.

Authors: Skakun Oleksii , Fedorov Sergiy , Seredyuk Nestor , Verbovska Olha
Published: December 2022

Background. An interleukin-6 (IL-6) is a proinflammatory cytokine which plays an important role in COVID-19-associated hyperinflammation.

Aim. This study aimed to assess the predictive ability of serum IL-6 levels for the development of severe/critical clinical conditions, a hypoxemic state requiring supplemental oxygen, and lethal outcomes in patients with COVID-19-associated pneumonia and arterial hypertension (AH).

Materials and Methods. One hundred and thirty-five unvaccinated patients hospitalized for COVID-19-associated pneumonia were enrolled in the study. AH was diagnosed in 78.5% of cases. Pneumonia was confirmed radiologically. SARS-COV-2 as an etiological factor was confirmed by either PCR or ELISA. In addition to conventional laboratory tests, IL-6, ferritin, and soluble interleukin-2 levels were measured.

Results. Among AH patients, the median levels of IL-6 were higher in non-survivors (95.1 [37.8 - 158.8] pg/mL) as compared to survivors (39.5 [13.6 - 81.1] pg/mL) (p=0.04). Among AH patients, the median serum level of IL-6 was 98.3 [37.8 - 158.8] pg/mL in critically ill patients, 41.7 [11.8 - 83.4] pg/mL in severely ill patients, 37.8 [13.6 - 74.4] pg/mL in moderately ill patients (p=0.051). The median serum level of IL-6 was lower at the time of discharge (6.5 [2.0 - 21.5] pg/mL) as compared to that on admission (43.2 [16.1 - 92.0] pg/mL) (p< 0.001). IL-6 level failed to predict severe/critical condition (AUC=0.59, p=0.13) and the need for supplemental oxygen (AUC=0.61, p=0.06); however, it might be used for the prediction of the lethal outcome (AUC=0.69, p=0.03). The cut-off value of IL-6 level for lethal outcome prediction of 91.0 pg/mL showed a sensitivity of 58.3% and a specificity of 78.7%. Patients with IL-6 levels > 91.0 pg/mL on admission had higher odds of lethal outcomes (OR = 4.87 [1.40 - 16.92], p=0.01).

Conclusions. Serum IL-6 level on admission did not show significant predictive ability for severe/critical conditions and hypoxemic states requiring supplemental oxygen in AH patients. However, serum IL-6 levels on admission were higher in non-survivors and might be used for the prediction of lethal outcomes with a cut-off value of 91.0 pg/mL in AH patients.
Clinical Outcomes After Use of Inhaled Corticosteroids or Oral Steroids in a COVID-19 Telemedicine Clinic Cohort: Retrospective Chart Review
Authors: Cellai Michele , Roberts Jodi , Moore Miranda A , Gandrakota Nikhila
Published: December 2022

Background

COVID-19 concerns remain among health care providers, as there are few outpatient treatment options. In the early days of the pandemic, treatment options for nonhospitalized patients were limited, and symptomatic treatment and home-grown guidelines that used recommendations from the Global Initiative for Asthma Management and Treatment were used.

Objective

The possibility that inhaled corticosteroids (ICS) might reduce the risk of respiratory symptoms and promote recovery was the impetus for this review, as it has already been shown that in the nonhospitalized patient population, oral corticosteroids (OCS) in the acute phase could have an adverse effect on recovery. We investigated if (1) patients treated with ICS were less likely to require referral to a post–COVID-19 clinic or pulmonary specialist than patients without ICS treatment or with OCS therapy, and (2) if OCS use was associated with worse health outcomes.

Methods

In a retrospective chart review, we identified all patients with acute illness due to COVID-19 that were followed and managed by a telemedicine clinic team between June and December 2020. The data were electronically pulled from electronic medical records through April 2021 and reviewed to determine which patients eventually required referral to a post–COVID-19 clinic or pulmonary specialist due to persistent respiratory symptoms of COVID-19. The data were then analyzed to compare outcomes between patients prescribed OCS and those prescribed ICS. We specifically looked at patients treated acutely with ICS or OCS that then required referral to a pulmonary specialist or post–COVID-19 clinic. We excluded any patients with a history of chronic OCS or ICS use for any reason.

Results

Prescribing ICS during the acute phase did not reduce the possibility of developing persistent symptoms. There was no difference in the referral rate to a pulmonary specialist or post–COVID-19 clinic between patients treated with OCS versus ICS. However, our data may not be generalizable to other populations, as it represents a patient population enrolled in a telemedicine program at a single center.

Conclusions

We found that ICS, as compared to OCS, did not reduce the risk of developing persistent respiratory symptoms. This finding adds to the body of knowledge that ICS and OCS medications remain potent treatments in patients with acute and postacute COVID-19 seen in an outpatient setting.

Published: December 2022

Background

Particulate matter (PM) is detrimental to the respiratory and circulatory systems. However, no study has evaluated the lag effects of weekly exposure to fine PM during the period from preconception to delivery on the risk of hypertensive disorders of pregnancy (HDPs).

Objective

We set out to investigate the lag effect windows of PM on the risk of HDPs on a weekly scale.

Methods

Data from women with de novo HDPs and normotensive pregnant women who were part of the Peking University Retrospective Birth Cohort, based on the hospital information system of Tongzhou district, were obtained for this study. Meteorological data and data on exposure to fine PM were predicted by satellite remote sensing data based on maternal residential address. The de novo HDP group consisted of pregnant women who were diagnosed with gestational hypertension or preeclampsia. Fine PM was defined as PM2.5 and PM1. The gestational stage of participants was from preconception (starting 12 weeks before gestation) to delivery (before the 42nd gestational week). A distributed-lag nonlinear model (DLNM) was nested in a Cox regression model to evaluate the lag effects of weekly PM exposure on de novo HDP hazard by controlling the nonlinear relationship of exposure–reaction. Stratified analyses by employment status (employed or unemployed), education level (higher or lower), and parity (primiparity or multiparity) were performed.

Results

A total of 22,570 pregnant women (mean age 29.1 years) for whom data were available between 2013 and 2017 were included in this study. The prevalence of de novo HDPs was 6.7% (1520/22,570). Our findings showed that PM1 and PM2.5 were significantly associated with an elevated hazard of HDPs. Exposure to PM1 during the 5th week before gestation to the 6th gestational week increased the hazard of HDPs. A significant lag effect of PM2.5 was observed from the 1st week before gestation to the 6th gestational week. The strongest lag effects of PM1 and PM2.5 on de novo HDPs were observed at week 2 and week 6 (hazard ratio [HR] 1.024, 95% CI 1.007-1.042; HR 1.007, 95% CI 1.000-1.015, respectively, per 10 μg/m3 increase). The stratified analyses indicated that pregnant women who were employed, had low education, and were primiparous were more vulnerable to PM exposure for de novo HDPs.

Conclusions

Exposure to PM1 and PM2.5 was associated with the risk of de novo HDPs. There were significant lag windows between the preconception period and the first trimester. Women who were employed, had low education, and were primiparous were more vulnerable to the effects of PM exposure; more attention should be paid to these groups for early prevention of de novo HDPs.
Implementation and Performance Analysis of Temperature and Humidity Monitoring System for Server Room Conditions on Lora-Based Networks
Authors: Effendi Siti Zubaidah , Oktiawati Unan Yusmaniar
Published: December 2022

Abstract – A server room is a room used to store applications, data and network devices such as routers. The server room is the data center of a company or institution in which there are applications and databases that store all important and valuable information for the company or institution concerned, therefore the server room must always be in good temperature conditions because the devices work for 24 hours no stopping. If there is a significant increase in temperature, it can cause system performance to be disrupted or hardware damage occurs. The cooler in the server room is not optimal because the cooler is often constrained by frequent power outages. From these problems, a solution is needed to be able to monitor the system remotely so that changes in room temperature can be seen in real time. The Internet of Things (IoT) is the solution to this problem, by using LoRa, which then sends the data to the Telegram application that has been installed on the smartphone so that real-time temperature changes can be obtained

Authors: Hameed Hadeel Faroak , Mohammed Alaa K. , Zageer Dheaa S.
Published: December 2022

For criminal investigations, fingerprints remain the most reliable form of personal identification despite developments in other fields like DNA profiling. The objective of this work is to compare the performance of both commercial charcoal and activated carbon powder derived from the Alhagi plant to reveal latent fingerprints from different non-porous surfaces (cardboard, plain glass, aluminum foil sheet, China Dish, Plastic, and Switch). The effect of three variables on activated carbon production was investigated. These variables were the impregnation ratio (the weight ratio of KOH: dried raw material), the activation temperature, and the activation time. The effect factors were investigated using Central Composite Design (CCD) software. The optimum activation conditions were found as an impregnation ratio of 1:2.6, activated time of 160 min, and temperature of 630oC. The results of the comparison show that Alhagi active carbon powder (AAC) has a high ability to develop latent fingerprints on all surfaces except on plastic surfaces while the commercial charcoal failed to develop the latent fingerprint on both plastic and aluminum foil sheets surfaces. AAC was found to clearly show every feature of the latent fingerprints more than commercial charcoal for both males and females. Also, AAC has the ability to show latent fingerprints till 15 days while commercial charcoal has the ability to show latent fingerprints just till 7 days.

Objectives The purpose of this study is as follows. First, we examine how learners have perceptions of Korean (classical) classes in the school field. Second, we examine the effects of classical fiction classes linked to visual thinking on learners' interest, confidence, attitude, and anxiety through pre-examination and post-examination. Third, by examining learners' responses to open questions about visual thinking, we examine the effect of classical novel classes linked to visual thinking on learners.
Methods A test was conducted on 165 middle school students in Incheon to measure variables related to visual thinking. We tried to analyze the results by collecting data through activity papers and questionnaires. The questionnaire was reviewed by experts (one Korean language professor and one Ph.D. in education) and divided into a pre-test and a post-test, and a survey was conducted to find out students' reactions to classical novel classes using visual thinking. The results of the survey were analyzed using SPSS 26.0, and open questions and activity papers were analyzed in content. Details of the analysis are as follows. In order to examine the effectiveness before and after the program, descriptive statistics were compared and analyzed for learners' pre- and post-test results.
Results Compiling the results of a survey of students after Korean language classes using visual thinking, it was found that classes using visual thinking were generally more satisfactory in the areas of learners' interest, confidence, attitude, and anxiety than conventional text-oriented classes.
Conclusions As an alternative to improving the problems of classical teaching patterns, this study could confirm the positive effect by using visual thinking in classical novel classes.

Practical moral education plan according to Aristotle's concept of happiness
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Yoon-kyung , Park Han-Sook
Published: December 2022

Objectives In this study, for a practical approach to a happy life, the philosophical concept of happiness is explored centered on Aristotle's Nicomachean Ethics. The purpose of this study is to find out the plan for practical moral education through.
Methods To this end, we conducted a literature study by examining the preceding research papers related to Aristotle's Nicomachean Ethics, and based on the analyzed content, we tried to suggest educational methods that can be practiced in the educational field in relation to the current elementary school morality and basic practical guidelines of the curriculum.
Results As a result, a moderate activity according to Aristotle's practical wisdom is a moral activity, that is, a virtuous activity, and such virtuous activity does not end as a one-time thing, but can be recognized as virtuous only when it is carried out with educational continuity. Since the formation of practical wisdom is possible through long life experiences on the premise of a perfect understanding of theoretical wisdom, it is necessary to have a pedagogical perspective that enables students to habituate the understanding of practical wisdom through practice in the field of elementary school.
Conclusions Therefore, an important purpose in moral education is an educational environment that allows students to achieve practical wisdom by themselves rather than approaching them through a knowledgeable dialogue about virtue so that they can lead true happiness and become a habit in life. It is necessary to incorporate practical moral education according to Aristotle's concept of happiness in school experience so that it can lay the foundation for habituation of virtue that can form and implement practical wisdom through self-understanding.

Published: December 2022

Objectives The purpose of this study was to look at the exhibitions that are naturally expressed in children's play, and to see how children-led exhibitions appear and what their meanings are.
Methods From November 21, 2019 to February 21, 2020, 18 children in a 4-year-old class participated and observed at a workplace daycare center located in Seoul. Data was collected. Based on the collected cases, meaningfully described dialogues were extracted through the process of ‘transcription-coding-topic generation’, and analyzed by categorizing them into 5 areas according to context.
Results Depending on the purpose and intention of the children, children's exhibitions are ‘exhibits without an audience only for me’, ‘exhibits that I want to show to someone’, ‘exhibits to play afterwards’, ‘exhibits to keep safely and to possess’. It was categorized as ‘Exhibition’. From secret private exhibitions that only oneself knows, to the types of exhibitions that change and expand while communicating with the members of the daycare center (children, teachers, parents, etc.), they appeared in a new and colorful appearance as they gradually changed. Children's play was exhibited as a single scene, and as time passed and the exhibition changed again, the circulation of play and exhibition was meaningful as a way for children to communicate with the world.
Conclusions Children's exhibitions were not simply intended to show the outcome of the work, but were a process that contained experiments and challenges that followed by play. Through exhibitions expressed in play, children expressed what they were interested in as a representation, and exhibited them in their own way to establish their own identity. By paying attention to the value of exhibitions led by children as a process of play where children's learning takes place, teachers should support children so that they can exhibit them in any way they want.

Published: December 2022

Objectives For the successful introduction and settlement of the high school credit system, it is important to expand the role of teachers related to the operation of the high school credit system and secure expertise. To this end, it is necessary to examine the actual difficulties experienced by high school teachers in the process of operating the high school credit system and derive the new role performance required by teachers based on this.
Methods Therefore, in this study, the difficulties experienced by teachers with experience in operating the high school credit system in terms of ‘formation of school culture’, ‘curriculum organization and operation’, ‘career and academic design guidance’, ‘school designs and support for related departments’, etc. were analyzed through focus group interviews. Then, we looked at the role of field teachers who are to operate the high school credit system in the future.
Results As a result of the analysis, it was found that teachers were required to have the ability to perform roles related to the formation of a school culture suitable for the operation of the high school credit system and the establishment⋅support of the operating system. In addition, since the organization and operation of the student-selective curriculum is the core of the high school credit system operation process, it was confirmed that it was essential for teachers to secure the role performance ability to prepare and operate the educational system that students need. Finally, it was found that teachers were required at a professional level to have the ability to perform roles that support students to design and perform their own studies according to their aptitude and career path.
Conclusions In the future, it is expected that understanding of the role of teachers essential for the operation of the high school credit system derived in this study will be helpful in providing various administrative support to secure teachers' expertise and improve their capabilities.

Objectives This study aims to overcome the practical difficulties of regionalization instruction in elementary schools by designing and developing a Wiki-based platform to assist elementary school teachers' instruction design as a knowledge-building community.
Methods To this end, this study applied a rapid prototyping methodology for dynamic interactions in the design, development, and evaluation process. First, We designed the platform by conducting a literature review and a needs analysis. Moreover, We developed the final platform through two formative cycles of prototype development and usability evaluation. Through the user experience analysis of the finally developed platform, the value and improvement points of the wiki-based regionalization instruction support platform were derived.
Results The final platform is a wiki platform based on Java, allowing easy materials modification through WYSIWYG editing. It has functions such as discussion, history, and statistical information. The number of wiki articles in the area, which was about 300 initially, has more than doubled to 765. As a result of user experience analysis, the usefulness of this platform is to support the design of regionalization instruction for teachers, update regionalization materials, provide effective learning resources for students, supplement the limits of book-type materials, and provide the experience of collective intelligence. On the other hand, we also confirmed subsequent issues such as reflection of students' level, management quality of information, enhancement of information productivity, enhancement of interactivity between users, and expansion of participants.
Conclusions This study is significant in that it provided practical support for the difficulties faced by teachers through using wikis as a knowledge-building community and that it derived meaningful suggestions that should be considered when designing wiki-based knowledge-building communities.

Published: December 2022

Objectives Universities have expanded various support to strengthen students' learning capabilities. However, the meaning and interpretation of learning capabilities were diverse and ambiguous, causing uncertainty in deriving directions for setting learning support goals and establishing promotion strategies. Recognizing these problems, this study aims to prepare evidence for establishing a university learning support system by analyzing trends in studies related to learning competency and extracting topics related to learning competency through text mining and network analysis.
Methods Basic statistical analysis, core word selection, topic extraction, and research trend were analyzed using keyword network analysis and LDA-based topic modeling techniques by collecting information on the titles and abstracts of 621 academic papers on learning competencies.
Results The keywords related to learning competency were groups, and the results of selecting key words were learning immersion, self-efficacy, self-regulated learning ability, learning community, problem-solving ability, cooperative learning, knowledge, and creativity. As a result of topic modeling, five topics were extracted, and they were named as learning motivation, learning analysis, learning execution, learning relationship, and learning expansion. Next, as a result of analysis of research trends related to learning competency, it was found that research on learning competency has continued to increase since 2010, and research on learning relationships and learning expansion topics has increased since 2015.
Conclusions This study is meaningful in that it identified the keywords mentioned in current learning-related studies to foster future talent, extracted and presented related topics, and presented basic data on finding effective support directions to improve student learning competency in universities.

Objectives This study tried to explore the direction of language network analysis-related research in the field of special education in the future by analyzing the trends of studies using language network analysis methods in the field of special education in Korea.
Methods For this purpose, 28 studies using language network analysis in the domestic special education field were analyzed from 2007 to June 2022. Based on previous research, the analysis criteria were set as ‘year of publication and published journal, research topic, analysis tool, visualization analysis method, and analysis index’.
Results As a result of the study, it was found that the largest number of studies were conducted in ‘Special Education Rehabilitation Science Research’ and ‘Intellectual Disability Research’. was found to have been carried out. In addition, most of the research was conducted on the subject of research trend and knowledge structure analysis, and it was found that the majority of collected texts were articles published in academic journals. As a network analysis tool, ‘UCINET’ was used the most, and the most studies that visualized the results through a network map were the most. In all 28 papers to be analyzed, the centrality scale was used as an analysis index, and methods such as clustering and ego network analysis were also used.
Conclusions These results have significance in providing a direction for conducting language network research in the field of special education in the future, and the need for continuous expansion of qualitatively more diverse topics, as well as network analysis tools, visualization presentation methods, and analysis suitable for research purposes and topics. The necessity of presenting the research results abundantly using indicators was suggested.
Efficient simulation of Gottesman-Kitaev-Preskill states with Gaussian circuits
Authors: Calcluth Cameron , Ferraro Alessandro , Ferrini Giulia
Published: December 2022

We study the classical simulatability of Gottesman-Kitaev-Preskill (GKP) states in combination with arbitrary displacements, a large set of symplectic operations and homodyne measurements. For these types of circuits, neither continuous-variable theorems based on the non-negativity of quasi-probability distributions nor discrete-variable theorems such as the Gottesman-Knill theorem can be employed to assess the simulatability. We first develop a method to evaluate the probability density function corresponding to measuring a single GKP state in the position basis following arbitrary squeezing and a large set of rotations. This method involves evaluating a transformed Jacobi theta function using techniques from analytic number theory. We then use this result to identify two large classes of multimode circuits which are classically efficiently simulatable and are not contained by the GKP encoded Clifford group. Our results extend the set of circuits previously known to be classically efficiently simulatable.

A pandemia da covid-19 transformou o ensino presencial para o modelo não presencial. O tempo de permanência em isolamento social modificou a percepção de saúde, o bem-estar e a qualidade de vida das pessoas. Assim, unindo ensino, pesquisa e extensão de forma virtual, desenvolveu-se um produto educacional cujo tema é a promoção da saúde. O produto é um guia de ações composto pela coletânea de projetos de ações extensionistas desenvolvidos durante o ensino interdisciplinar não presencial. A metodologia utilizada foi a baseada em projetos colaborativos, de cooperação e interdisciplinar, em parceria com a comunidade e com base na realidade local em saúde. O produto denominado A Promoção da Saúde em Tempos de Pandemia: um guia para a prática, o ensino e a extensão em Fisioterapia, contém 35 projetos, desenvolvidos durante quatro semestres letivos e separados em três partes, de acordo com a situação de isolamento social, a saber: 1. Estresse, ansiedade, biomecânica e dor durante a pandemia; 2. Isolamento social prolongado; 3. Retorno presencial e diminuição das restrições à participação. Espera-se que o produto possa auxiliar o ensino e a extensão em cursos de graduação em Fisioterapia e o fisioterapeuta em sua prática de promoção da saúde da população, em tempos de isolamento social ou não, e de forma virtual ou presencial.

Em 2020 o mundo foi atingido pela pandemia da COVID-19, causada pelo vírus SARS-CoV-2, que desencadeou a impossibilidade de realizar atividades presenciais pelo isolamento e o distanciamento social. A Internet se tornou uma grande fonte de informações sobre a COVID-19. Versões distorcidas dos fatos começaram a ser disseminadas pelas pessoas por este meio, as quais se aproveitaram da desinformação, do medo, e da insegurança da população para criar narrativas de comunicação científica errôneas. No auge da pandemia, devido às condições sociais, o Instagram, que é uma poderosa ferramenta de comunicação no contexto das redes sociais, e possui um alto alcance, foi altamente utilizado para disseminar informações sobre a pandemia. Visando contribuir para disseminação de informação acessível e segura sobre COVID-19 e assuntos relacionados a saúde, nosso grupo criou um perfil no Instagram denominado @grupo.cienciagram em julho de 2021. O @grupo.cienciagram foi criado por estudantes do Instituto Oswaldo Cruz, sendo composto por: uma doutora, uma aluna de doutorado, um aluno de mestrado e três alunas de iniciação científica. Nele são disponibilizadas informações nos formatos: (1) “postagem rápida”, (2) “postagem carrossel”, (3) vídeos em reels e (4) vídeos de IGTV, abordando temas como: segurança e eficácia das vacinas; a diferença entre seus mecanismos (diferentes tipos); o significado dos testes de IgG e IgM; o que são variantes de um vírus, entre outros. Em seis meses de atividade, foram feitas 68 postagens e durante esse período o perfil acumulou mais de sete mil seguidores, com reels que chegaram a atingir mais de 2 milhões de visualizações. As análises das métricas de acesso e visualizações foram feitas a partir dos dados do Instagram Insights. Nossos dados demonstram que o Instagram é uma rede social com grande potencial para disseminação de informações de qualidade sobre saúde e para a divulgação científica com grande visibilidade. PALAVRAS-CHAVE: COVID-19; coronavírus; divulgação científica; Instagram.
