Published: May 2021

BLE beacon in an indoor location, battery efficiency usage must be right. Power beacons as one of the keys that need to be optimized. The decrease in power beacons will decrease the estimated distance from an indoor location based on the RSSI value. Therefore, an additional method is needed to recover the estimated distance's accuracy value due to the reduced power. In this paper, the method for recovery accuracy is by using a gaussian filter. Measurements were made at the same position on 3 BLE signals from multipower transmitters, which differed in their transmit power (TX power -1 dBm, -9 dBm and -20 dBm). The first six points are selected with the position of the line of sight as environment 1, and the second six points are chosen with the position of non-line of sight as environment 2 (obstructed). The first point of each environment is used as a reference. In environment 1, transmit power reduces the 24 dB effect to a decrease in accuracy distance estimation. The Gaussian effectiveness filter for improvement accuracy at all measurement points or 100%. In environment 2, reduce power transmit 12 dB is not followed by a decrease in accuracy distance estimation. The effectiveness of the Gaussian filter for improving accuracy is 60% of the number of measurement points. Finally, the Gaussian filter in the power optimization can provide recovery accuracy distance estimation is 80% from measurement sample for environment 1 and environment 2.

Mercury (Hg) as a gold extractor can cause environmental pollution, therefore, hyperaccumulator plants are needed, such as mustard greens (Brassica juncea L). Research on the effect of planting time of mustard greens on the adsorption of mercury (Hg) metal ion on contaminated soil waste has been carried out. The purpose of this research was to determine the concentration and adsorption mechanism of Hg metal ion from contaminated soil at roots and canopy of mustard plants at various planting times. Amount of Hg metal ion adsorbed on the roots and canopy of mustard greens at 2, 4, and 6 weeks of planting times were analyzed using Atomic Absorption Spectrophotometry (AAS). The results showed that the average levels of Hg metal ion adsorption at various planting time of 2, 4, and 6 weeks at roots were 156.611 μg/g, 810.256 μg/g, and 888.711 μg/g, respectively, and at the canopy were 69.486 μg/g, 134.580 μg/g, and 60.416 μg/g, respectively. The planting time of 6 weeks resulted in the highest adsorption ability of Hg at the roots. The results of the bioconcentration factor (BCF) test showed that the adsorption of Hg in the roots and canopy of the mustard plant took place using a phytoextraction mechanism (BCF < 1).

Liquid smoke contains acid, carbonyl, and phenolic compounds, so it is very appropriate to be used as a preservative. Traditional smoking can be replaced with liquid smoke because it is safer and more practical. The study of the use of coconut shell liquid smoke has been used in skipjack fish to determine the effect of liquid smoke concentration and storage time on dissolved protein content and total bacteria in smoked fish. The quality of smoked fish was determined by two treatments, namely the variation in the concentration of liquid smoke (2, 3, 4, and 5%) and storage time (2, 4, 6, 8, and 10 days). The results showed that the best concentration of liquid smoke to produce smoked skipjack fish is 3% with a water content of 62.41% and dissolved protein content of 17.58%. The maximum storage time of smoked skipjack tuna is 6 days with a total plate count (TPC) value or total bacteria 1.8 x 105.

Schistosomiasis is a disease caused by Schistosoma japonicum worms and Oncomelania hupensis lindoensis as the intermediate snails. Praziquantel is a drug used to reduce the prevalence of schistosomiasis. However, its use has several side effects such as headaches, dizziness, nausea, vomiting as well as abdominal, joint, and muscle pain. The development of alternative drugs is a solution to reduce side effects. Betel (A. catechu) seeds are known to the public to have an anthelmintic effect because they contain alkaloids, tannins, flavan, phenolic compounds, as well as arecoline. To increase the bioavailability and efficacy of the extract, the seeds were prepared in the formulation of nanoparticles. This study aims to determine the antischistosomiasis activity of the ethanol extract nanoparticles of betel nut as an antischistosomiasis. The rats were divided into 9 treatment groups consisting of normal, negative and positive control groups, extract treatment and treatment of nanoparticle preparations with dose variations of 30, 60, and 120 mg/kgBW. The parameter observed was the number of S. japonicum eggs in rat feces before and after treatment. Data obtained from the mean number of S. japonicum eggs was tested for normality with Saphiro-Wilk test, and showed that the data were not normally distributed. Furthermore, nonparametric statistical analysis was carried out with Kruskal-Wallis which showed there was no significant difference in the mean number of S. japonicum eggs in all treatment groups. The results showed that the ethanol extract nanoparticles of A. catechu had antischistosomiasis activity.

This study was conducted to determine the organic constituents and to test the antioxidant activity and toxicity of gaharu fruit pulp extract (Aquilaria malaccensis Lamk.). Gaharu fruit pulp extract was obtained through Microwave Assisted Extraction (MAE) method and then extracted with a solvent with different polarity, namely ethyl acetate and n-hexane. The obtained yield of ethyl acetate extract of the gaharu fruit pulp was 40.827% w/v, whereas 0% w/v in n-hexane extract, therefore, no further test for n-hexane extract, so that the n-hexane extract was not tested for the next stage. The results of the organic constituents of the ethyl acetate extract of gaharu fruit pulp showed flavonoids, saponins, glycosides, phenols and tannins. Antioxidant activity testing was carried out using the DPPH method with vitamin C as a positive control. The results of the antioxidant activity test showed that IC50 of ethyl acetate extract of gaharu fruit pulp and vitamin C were 143.789ppm and 13.797ppm, respectively. Extracts from microwave-assisted maceration that were partitioned with ethyl acetate solvent were categorized into moderate antioxidants because the IC50 value was between 101-150ppm, while vitamin C was categorized as a strong antioxidant because the IC50 value was between 0-100ppm. Toxicity testing was also carried out on ethyl acetate extract of gaharu fruit pulp using the BSLT method. The results of the toxicity test of the ethyl acetate extract of gaharu fruit pulp showed activity with an LC50 value of 11.282ppm. Based on this research, the ethyl acetate extract of gaharu fruit pulp is considered to have an anticancer potential.

Mandar coconut oil is one of the coconut processed products, which has become superior product in West Sulawesi especially in Majene regency. Unfortunately, the Mandar coconut oil can’t be used more than a month because the water content and free fatty acid content of the oil have exceeded the maximum standard of SNI, so it can adversely affect on health. On the other hand, the existence of rice husk in Indonesia itself especially in West Sulawesi has not received attention and is limited to a few needs such as for ash or livestock feed, and the rest is thrown away. This research aims to determine the effect of rice husk ash addition on the increasing of Mandar coconut oil quality. Completely randomized design was used in this research with 6 rice husk ash concentration variation levels i.e. 0%, 5%, 10%, 15%, 20% and 25%. The result shows that the addition of rice husk ash with 10% to 25% can reduce the water content of the oil until the quality standard of SNI is full filled. The highest reduction of water content was reached with 25% of rice husk ash concentration with 81% of reduction percentage. While, the addition of rice husk ash with 15% concentration can reduce the free fatty acid content of Mandar coconut oil until 32%.
Conserved Peptide Upstream Open Reading Frames Act Via Ribosome Stalling to Regulate Translation in Response to Environmental Signals.
Authors: Causier Barry , Hopes Tayah , McKay Mary , Paling Zachary , Davies Brendan
Published: May 2021

The regulation of protein synthesis plays a key role in growth and
development in all organisms. Upstream open reading frames (uORFs) are
commonly found in eukaryotic mRNA transcripts and typically inhibit
translation of downstream ORFs, in part by stalling ribosomes. Conserved
peptide uORFs (CPuORFs) are a rare subset of uORFs, some of which
conditionally regulate translation. Here we identify three Arabidopsis
CPuORFs that specifically regulate translation of any downstream ORF, in
response to the agriculturally significant environmental signals, heat
shock and water limitation. Mechanistically, we provide evidence that
CPuORF translation causes ribosome stalling, in a peptide
sequence-dependent manner, attenuating translation of downstream ORFs.
We propose a model in which plant CPuORFs are not simply on/off switches
for translation, but rather act conditionally, along a continuum, to
fine-tune translation dynamically.

Objective: We aimed to evaluate histopathologic alterations in the lung,
heart, liver, and spleen of coronavirus disease 2019 (COVID-19)
decedents through postmortem core needle biopsies. Materials and
Methods: Patients who died of reverse transcription-polymerase chain
reaction-proven COVID-19 were included in this postmortem case series.
Postmortem percutaneous ultrasound-guided biopsies using 14- and
16-gauge needles were performed in the lungs, heart, liver, and spleen.
Biopsy samples were stained with hematoxylin-eosin and examined under a
light microscope. Clinicodemographic characteristics, chest computed
tomography (CT) images, and COVID-19-related treatments of the patients
were also collected. Results: Seven patients were included in this
study. Liver and heart tissue samples were available from all patients,
and lung and spleen tissues were available from five and three patients,
respectively. Chest CT images predominantly revealed bibasilar
ground-glass opacities. Lung biopsies showed diffuse alveolar damage in
all biopsy specimens. Heart findings were nonspecific and largely
compatible with the underlying disease. Patchy necrosis, steatosis, and
mononuclear cellular infiltration were the main findings in the liver
biopsies. Splenic histopathological examination showed that splenic
necrosis and neutrophil infiltration were the common findings in all
patients. Conclusion: Tissue acquisition was complete for the heart and
liver and acceptable for lungs. The amount of tissue was sufficient for
a proper histopathologic examination. The histopathological findings
were generally in accordance with previous autopsy studies. The lung
radiological findings were also correlated with the histopathologic
findings. We consider that a postmortem biopsy is a feasible alternative
for histopathological examinations in COVID-19 decedents.

Authors: Zengin Mürşide , Başoğul Ceyda , Yayan Emriye Hilal
Published: May 2021

Aim: The aim of this study was to determine the anxiety levels of
parents with children aged 3-6 years due to the COVID 19 pandemic and to
examine the effects of Solution Focused Brief Therapy (SFBT) applied to
parents with high level of anxiety. Methods: The study was conducted as
a parallel-group, randomized controlled design. The sample of the study
consisted of 77 parents who were randomly assigned to the experimental
and control groups (control group n = 40; intervention group n = 37).
One session of online SFBT was applied to the intervention group each
week and 4 sessions were applied in total. No intervention was applied
to the control group. The data were collected using introductory
information form and State-Trait Anxiety Inventory (STAI). SPSS
programme and Analysis of Moment Structures (AMOS) 23 application were
used in the analysis of the data. Structural equation modeling was used
to examine a hypothesized model that SFBT has both direct and indirect
effects on anxiety levels of parents. Results: The state and trait
anxiety mean scores of the intervention group decreased compared to the
pre-intervention mean scores after the implemented programme. While this
difference between state anxiety scores was statistically significant
(p≤ .001), the difference between trait anxiety scores was not
statistically significant (p> .05). There was no
statistically significant difference between the pre-test and post-test
STAI-S and STAI-T total scores of the control group. Conclusions: In the
study, it has been found that SFBT applied to parents with high level of
anxiety is an effective method in reducing the state anxiety levels of
parents.

Authors: mirzaei khadijeh , bahrampour niki , Mirzababaei Atieh , shiraseb Farideh
Published: May 2021

Background: Obesity is a global issue. Energy density (ED) can influence
on body compositions (BCs). Consumption of HED (high energy density)
foods can increase body fat mass (BFM) and inflammatory markers.
Methods: This study was a cross-sectional research among 391 women. Body
composition analyzer (BIA) and food frequency questionnaire (FFQ) was
used to assess BCs and food intake of individuals. Blood samples and
serum level of high-sensitive C-reactive protein (hs-CRP), plasminogen
activator inhibitor- 1 (PAI-1) and transforming growth factor-β
(TGF-beta) were collected. ED per one gram of foods were calculated and
divided to quartiles. Linear logistic regression tests were used to
investigate the association between BCs across quartiles of ED intake.
Results: Results demonstrate skeletal muscle mass (SMM), total body
water (TBW), intracellular water (ICW), fat free mass (FFM), visceral
fat area (VFA) and fat free mass index (FFMI) was seem to be under the
effect of hs-CRP among ED intakes. TBW, extracellular water (ECW), FFM
with PAI-1, bone mineral content (BMC) with PAI-1 and TGF-beta, and
Skeletal lean mass (SLM) with hs-CRP were inversely associated. Fat
right arm (FRA), fat right arm (FLA), fat right and left leg (FRL,FLL),
fat trunk, TBW, ICW, ECW, BFM, FFM, SMM, SLM, waist circumference (WC),
FFMI and FMI were positively under the influence of TGF-beta after
following higher ED food intakes. FRA, FLA, FRL, FLL, fat trunk, ICW,
BFM, SMM, SLM, WC, FFMI and FMI were positively under the influence of
PAI-1. Conclusion: All adipose tissue content of subcategories of BC
were strongly associated with ED intake in the mediatory role of PAI-1
and TGF-beta.

Published: May 2021

Objective: De Quervain tenosynovitis is the most common cause of lateral
wrist pain. The diagnosis can be made with the Finkelstein test when
pain is provoked with wrist ulnar deviation. Conservative treatment
including rest, non-steroidal anti-inflammatory medication and physical
therapy is applied first, then there may be a need for corticosteroid
injections, and in resistant cases, surgery. The aim of this study was
to evaluate the effectiveness of neural therapy (NT) on pain and hand
functions in patients with De Quervain tenosynovitis. Methods: A total
of 36 patients admitted between May 2019 and March 2020 were randomly
assigned to neural therapy (NT) and control groups. Hand rest and thumb
spica splint were applied to all the patients, and NT interventions to
the NT group only. A visual analog scale (VAS) and the Duruöz Hand index
(DHI) were used to measure pain and functionality at baseline, then at 1
and 12 months after the end of the treatment. Results: The NT and
control groups both showed improvements in VAS and DHI scores at 1 and
12 months compared to baseline. The VAS scores were significantly lower
at both 1 and 12 months compared to baseline in the NT group. The DHI
scores were lower in the NT group at 1 month, and at 12 months there was
no significant difference between the two groups. No adverse effects
were seen in any patient. Conclusion: NT seems to be effective in
reducing pain and improving hand functions in patients with De Quervain
tenosynovitis.

Objective: To analyze the serum markers for the early diagnosis of
intestinal anastomotic leak (AL) after the gyne-oncological operations.
Methods: Between September 2017 and March 2021, patients with an
intestinal anastomosis performed during the gyne-oncological surgeries
were identified from a tertiary center in Turkey. As the local guideline
of the clinic, all these patients were followed by measuring serum
samples including procalcitonin (PCT) and C-reactive protein (CRP) on
postoperative day (POD) 1 through the day of discharge or the day of
re-operation for AL. Results: 12.5% (5/40) of the patients suffered an
AL and 4 of them were re-operated. The mean albumin values on POD 3-4
and the mean platelet values on POD 1 were lower in the AL group
(p<0.05). Although it was not statistically significant
(p>0.05), median PCT values (ng/mL) on POD 8-10 were higher
in the AL group compared with no leak group. The best cutt-off point for
PCT on POD 9 was determined to be 0.11 ng/mL (AUC: 0.917, Sensitivity =
%100.0, specifity = %66.7, positive predictive value = %66.7,
negative predictive value = %100.0). Conclusion: Serum PCT and CRP
concentrations were not found to be helpfull for the early diagnosis of
AL in patients operated for gyne-oncological malignancies. Low levels of
albumin and platelets in the first days after the operation may be clue
for a possible AL.

Objectives: Discharging a child home on long term ventilation (LTV) via
tracheostomy is complex and involves multiple healthcare providers
across healthcare sectors. To date, patient and family feedback of a
newly developed LTV discharge pathway has been anecdotal. Our objective
was to explore the perceptions of family caregivers (FCs) that have
completed the LTV pathway to home with respect to their: (1) experience
with transitions across the pathway (2) perceptions of competency
attainment and, (3) viewed opportunities for improvement. Methods: We
conducted 11 semi structured interviews with FCs. Interviews focused on
FCs experience with the training process, perception of competency from
a knowledge and skill perspective and opportunities for improvement.
Interviews were audiotaped, transcribed verbatim, coded and analyzed
using an inductive thematic analysis approach. Results: Eight mothers
and 3 fathers of 10 children participated. Six primary themes were
identified: 1) making an informed decision, 2) transitioning to
rehabilitation, 3) building capacity for self-care, 4) coordinating case
management, 5) readying for discharge home and, 6) experiencing home
care. Conclusion: Overall, FCs felt that the preparation and transition
support obtained through the application of a standardized LTV discharge
pathway allowed successful attainment of new knowledge and skills
necessary to care for their child with LTV at home.

Recentemente, o baixo desempenho dos estudantes brasileiros nas avaliações internacionais ganhou os noticiários, levantando a suspeita de que a qualidade da educação científica no país esteja em queda. Neste artigo, inspirados pela sociologia da educação de Pierre Bourdieu, nós investigamos o efeito da desigualdade social no desempenho dos estudantes brasileiros em Ciências da Natureza. Uma amostra representativa de todos os participantes do ENEM entre 2012 e 2019 (n = 489.167) foi submetida a uma análise de correspondência múltipla ajustada e inserida em um modelo linear multivariado. Como primeiro resultado, observamos que a origem social é capaz de explicar mais de 35% do desempenho em ciências dos estudantes. Logo, grande parte do sucesso escolar é devido ao privilégio de classe. Por outro lado, frequentar uma escola privilegiada é mais importante que nascer em uma família privilegiada, pois o efeito social da escola mostrou-se quase quatro vezes superior ao efeito social individual. Esses resultados trazem implicações importantes para pensarmos criticamente a educação científica em vista da ideologia do mérito e da distribuição desigual de recursos e oportunidades no sistema educacional.

Los objetivos que direccionaron el presente estudio fueron diseñar y evaluar una propuesta de enseñanza sobre la nutrición humana desde una perspectiva multidisciplinar, siguiendo los fundamentos didácticos del enfoque por indagación y el trabajo colaborativo. Los grupos participantes estuvieron conformados por alumnos del grado séptimo (N=109) de una Institución Educativa de carácter oficial de la ciudad de Medellín - Colombia. Se llevó a cabo un diseño cuasi-experimental con aplicación de un test de asociación de conceptos, antes y después de la intervención, el cual fue analizado por el método de agrupaciones jerárquicas. Así mismo, se compararon los resultados del cuestionario final utilizando la prueba t de Student. Ambas técnicas de análisis permitieron evaluar cambios en las relaciones conceptuales como fruto de la intervención, siendo esto un indicador de que la propuesta favoreció la comprensión de los estudiantes sobre la nutrición humana, en comparación con aquellos que siguieron el método de enseñanza convencional.

O Programa Institucional de Bolsas de Iniciação à Docência (PIBID) do Ministério da Educação tem como objetivo promover a integração entre educação básica e educação superior, inserindo os futuros profissionais no cotidiano da rede pública de educação brasileira. Desde a sua implantação, em 2007, estudos vêm defendendo a necessidade desse programa para formação dos futuros profissionais da educação, uma vez que contribui para o desenvolvimento da práxis pedagógica baseada na ação docente refletida. Sendo os estudantes dos cursos de licenciatura os principais agentes desse programa, esse estudo tem como questão de pesquisa: De que maneira os estudantes avaliam o PIBID? Assim, objetiva analisar a percepção dos estudantes dos cursos de licenciatura da Universidade Federal da Bahia acerca das contribuições do PIBID para formação docente. É um estudo de caso, de abordagem qualitativa, que utilizou como recurso de pesquisa as entrevistas semiestruturadas com estudantes. Foram entrevistados 18 estudantes bolsistas, vinculados a 9 cursos de formação docente, dos turnos diurno e noturno, ofertados pela UFBA. A partir da análise de conteúdo, foi possível identificar que os estudantes expressaram a relevância do PIBID enquanto política pública necessária para a formação dos futuros docentes. Por outro lado, reconheceram que apesar de ser inovação pedagógica com impactos significativos na formação docente e para a valorização profissional, o contingenciamento de recursos, por parte do governo federal, impõe desafios para o desenvolvimento do programa.
UM PERFIL DA INTERFACE ENTRE SENSIBILIDADE MORAL E COMPREENSÃO DE NATUREZA DA CIÊNCIA DURANTE A RESOLUÇÃO DE QUESTÕES SOCIOCIENTÍFICAS

Published: May 2021

Na resolução de questões sociocientíficas há uma interação de elementos distintos que se apresentam em dimensões de preponderâncias científicas mais internalistas (e.g., natureza da ciência) e em dimensões sociais (e.g., crença, cultura, moralidade). No entanto, ainda existem lacunas de conhecimentos minuciosos e empiricamente abalizados sobre o dinamismo e as características relacionais dos elementos que constam na interface dessas duas dimensões, notadamente aquelas que envolvem elementos da moralidade e da compreensão da natureza da ciência. Com a intenção de reduzir essa lacuna, realizamos uma pesquisa que teve como objetivo traçar um perfil relacional da interface entre sensibilidade moral e compreensão da natureza da ciência durante a resolução de questões sociocientíficas. Os participantes da pesquisa foram 14 alunos de um curso de Licenciatura em Ciências Biológicas de instituição pública brasileira. A pesquisa adotou uma abordagem qualitativa, na qual foram analisados os discursos e os materiais escritos dos licenciandos sobre a compreensão da natureza da ciência e os aspectos de sensibilidade moral manifestados no processo de resolução de um estudo de caso sobre xenotransplante. O perfil interfacial evidenciou que, embora exista uma dinâmica relacional entre elementos de natureza da ciência e sensibilidade moral, esse perfil é marcado pela predominância de elementos isolados de sensibilidade moral.

As atividades e as práticas humanas, assim como os processos de ensino e aprendizagem, são estruturadas por meio das linguagens e seus signos que podem ser produzidos de diversas maneiras, constituindo um fenômeno de comunicação e construção de sentidos (semiose). Este trabalho investiga as formas pelas quais os licenciandos em Química abordam conceitos, entidades, modelos e fenômenos científicos a partir da expressão artística do desenho. Para isso, analisamos, segundo a semiótica de Charles Sanders Peirce, seis desenhos produzidos por estudantes de licenciatura em Química representando os elementos carbono e mercúrio e suas substâncias. Assim, entendemos o papel dos licenciandos não só como observadores, mas também como criadores de símbolos, ícones e índices. As análises guiadas pelos pontos de vista qualitativo-icônico, singular-indicativo e convencional-simbólico propostos por Santaella (2018) apontaram uma pluralidade de construções de significados, oportunizada pela expressão artística, pela experiência estética e pelo conhecimento científico abordado em cada imagem. A apropriação de símbolos convencionados pela Ciência na identificação do elemento químico representado nem sempre assumiu um papel central na semiose, especialmente quando eram tratadas as propriedades e aplicações das substâncias. Nestes casos, os licenciandos optaram por uma mediação sígnica estruturada por criações próprias, utilizando-se de diferentes formas, cores e proporções.

Este estudo, de abordagem qualitativa e caráter exploratório, teve como objetivo compreender a experiência de famílias em um museu de ciência, com destaque para as interações e conteúdo conversacional. Participaram do estudo quatro grupos de famílias com crianças em visita espontânea ao Museu de Ciência e Tecnologia (MCT) da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS). O estudo contou com o registro audiovisual das relações das famílias com seus pares e com as exposições e, como instrumento de análise, utilizou-se um protocolo que combina aspectos teóricos e empíricos da interatividade. Os resultados indicam que, durante as visitas, as famílias conversam sobre aspectos das exposições, contemplando ou lendo textos e participando plenamente das atividades propostas. No entanto, foram reduzidas as conversas sobre temas de ciência. As análises sugerem que os pais, em maior ou menor intensidade, exerceram um papel importante de assistência e orientação das crianças, por exemplo, ao fornecerem instrução e apoio na interpretação para entender os conhecimentos científicos expostos, participarem em atividades e estimularem conexões com experiências anteriores que contribuíram para conversas nas quais emergiram reflexões de diversas naturezas e comportamentos de aprendizagem.

A Educação Popular pode contribuir na formação de cidadãos capazes de atuar na luta pela promoção da saúde, por incentivar diálogos e a participação popular na tomada de decisões. Jogos didáticos podem ser pensados para estimular debates que considerem a saúde de forma ampla, o que poderia ser de grande importância na questão das arboviroses, pela promoção de diálogos contextualizados com a realidade da população. Neste estudo, foi realizada uma revisão integrativa para mapear, no Brasil, o quanto os jogos didáticos relacionados ao mosquito Ae. aegypti e arboviroses apresentam enfoque em Educação Popular. Foram feitas buscas nas bases Google Acadêmico, Biblioteca Virtual em Saúde e Scielo. Foram analisadas características dos jogos didáticos tais como o tema abordado, a linguagem utilizada, modalidade (individual ou em grupo) e público-alvo, permitindo um mapeamento e síntese qualitativa dos jogos identificados pela busca. A fim de identificar características de Educação em Saúde, foram elaborados critérios para analisar com que concepção de educação em saúde os jogos mais se identificavam e balizar a análise do referencial teórico apresentado pelos trabalhos. Oitenta e um trabalhos foram incluídos, descrevendo setenta e dois jogos, em sua maioria voltados para o ensino formal e fundamental. Prevaleceu nos jogos o enfoque em Educação Sanitária, caracterizado pela ênfase em transmitir informações como tratamento e sintomas, ciclo biológico do vetor e formas de prevenção. A participação popular era reduzida à execução de ações individuais de controle do mosquito, com ênfase na necessidade de eliminar criadouros apenas no âmbito das residências. Apesar de alguns jogos apresentarem características de Educação Popular em seu embasamento teórico, em nenhum o tema Saúde foi abordado de forma abrangente, englobando aspectos socioeconômicos, culturais e ambientais. Os resultados apontam uma importante lacuna na produção e avaliação de jogos didáticos que problematizem os temas mosquito Ae. aegypti e arboviroses através de diálogos que valorizem os saberes populares e estimulem a ação popular na busca de soluções, no planejamento e tomadas de decisões.
CIÊNCIA, ARTE E FILOSOFIA: MOBILIZANDO DISCURSOS NO USO EDUCATIVO DO CINEMA NUMA ATIVIDADE NÃO FORMAL

Published: May 2021

Este artigo tem como objetivo compreender o uso educativo do cinema na divulgação científica no âmbito de uma atividade não formal de ensino, que incluía o debate com um convidado após a apresentação do filme, do gênero ficção científica, “A Origem” para uma audiência diversificada (estudantes universitários, moradores da cidade e turistas). Analisamos o discurso empreendido pelo convidado considerando interfaces entre ciência, filosofia e arte, sob a perspectiva histórico-cultural, teoria da atividade e do materialismo histórico e dialético. Os resultados apontam para diferentes estratégias enunciativas, dentre elas: a mobilização de saberes de distintas esferas de criação ideológica - ciência, arte e filosofia - enquanto sistemas estruturados de produção e atuação humana; e o estabelecimento de vínculos ontológicos (ciência-realidade; ciência-ficção e filosofia-ficção) com os objetos discursivos da sessão comentada de cinema. O caso analisado mostra, ainda, que atividades educativas podem ser melhor compreendidas como compostas por subordinação de ações estruturadas e conscientes.
A TEORIA DA EVOLUÇÃO EM QUADRINHOS: UMA ANÁLISE DA REVISTA “SAIBA MAIS SOBRE CHARLES DARWIN”
Authors: Vieira Júnior José João , De Almeida Sheila Alves
Published: May 2021

O presente artigo se configura como uma pesquisa documental com o objetivo analisar a Revista em quadrinhos “Saiba Mais sobre Charles Darwin”. Essa publicação foi comercializada nas bancas, e transita entre a fantasia que busca o entretenimento e a apresentação de conceitos sobre Evolução Biológica. Para a análise do objeto, em todas as páginas da revista foi observado como os quadrinistas utilizaram os recursos visuais em combinação com a linguagem verbal, e como eles se complementam contribuindo para a propagação da mensagem científica expressa pelos quadrinhos. Os resultados indicaram que a maioria dos quadrinhos apresentam verbetes. Em alguns quadrinhos da revista, a mudança abrupta de estilo nos desenhos revela certa dificuldade da indústria de entretenimento de transitar pelo gênero de divulgação científica para as crianças. Os textos escritos dos quadrinhos apresentam marcas discursivas bem acentuadas tais como definições, exemplificações e explicações. Assim, a obra apresenta um saber estável, não problemático, inquestionável, o que contrasta com o próprio conhecimento científico, que é assumidamente provisório, problemático, discutível. A chancela editorial opta por uma visão estereotipada do cientista como alguém que já se anunciava cientista. Contudo, reitera-se a importância da “Saiba Mais sobre Charles Darwin” para a promoção da leitura e a democratização da linguagem de divulgação científica para crianças. Pois, a revista analisada evidencia uma das mais importantes teorias cientificas, que mudou significativamente a forma como observamos o mundo natural, em um momento de grande pressão para enfraquecimento da teoria da evolução, através da tentativa de validação do criacionismo como teoria cientifica.
AS REPRESENTAÇÕES DA CIÊNCIA EM MATÉRIAS DE UMA REVISTA DE DIVULGAÇÃO CIENTÍFICA: A COSMOLOGIA SUPERINTERESSANTE

O presente artigo é produto de uma pesquisa de Mestrado em Educação desenvolvida junto à Universidade Federal do Triângulo Mineiro. Nela defendemos o pressuposto de que a educação científica de uma sociedade não deve ser atribuída unicamente ao espaço escolar e aos espaços de educação formal. Acreditamos que toda a sociedade, em seus diversos tempos e espaços, deve contribuir para esta promoção. Também consideramos que a ciência é um campo de construção de produtos culturais materiais e simbólicos, os quais incluem visões e concepções acerca do que do que é, quem faz e como se faz ciência. Compreendemos que essas concepções são promovidas pela e na sociedade via atores sociais que promovem a educação científica supracitada. Desse modo, consideramos interessante investigar como a ciência é apresentada em uma revista de divulgação científica que apresenta mais apelo ao público jovem no Brasil, a SuperInteressante, em sua versão digital, no período de 2010 a 2019. O delineamento da pesquisa se deu a partir de matérias que tinham como principal tema a Cosmologia, devido ao forte apelo que esse tema possuí e por sua ainda reduzida presença nas salas de aula brasileiras. A análise empreendida sobre os textos foi de natureza qualitativa, por meio da Análise Textual Discursiva. Compreendemos 5 elementos que consideramos fundamentais para compreender a apresentação da ciência na revista em questão, as quais se configuraram como nossas principais categorias: (i) conhecimento científico, (ii) trabalho científico, (iii) cientista, (iv) desenvolvimento científico e (v) suas influências. Identificamos apresentações consideradas adequadas a respeito do empreendimento científico, mas também uma visão por vezes ficcional desse campo do saber. Discutimos e concluímos a respeito das influências que essas apresentações podem ter sobre a sociedade e o público leitor desta publicação.
