A QUÍMICA NA LITERATURA DE PRIMO LEVI: ASPECTOS FILOSÓFICOS SOBRE EXPERIMENTAÇÃO, MATÉRIA E OFÍCIO QUÍMICO
Authors: Valero Rafaela , Mori Rafael , Massi Luciana
Published: January 2023

CHEMISTRY IN PRIMO LEVI’S LITERATURE: PHILOSOPHICAL ASPECTS ON EXPERIMENTATION, MATTER AND THE PROFESSION OF CHEMISTRY. The Italian chemist Primo Levi (1919-1987) published a testimonial literature about the period he was captive in Auschwitz, later exploring other literary genres. In his work as a whole, the science-art relationship takes place both in terms of content (when chemistry and scientific knowledge are themes) and form (when the author appropriates the language and logic of science to communicate his experiences, especially those lived in the concentration camp). Three themes related to the chemical universe are present in Levi’s writings: experiments, man’s relationship with matter and chemistry as a work. In this article, we bring these topics closer to current discussions in the field of philosophy of chemistry. The philosophical discussion and Primo Levi’s literature converge on the understanding that experiments assumes a particular role in chemistry, that matter is a central category for this science and that the chemical profession raises ethical questions, such as those related to impacts of the incessant production of new substances.
EFFECT OF ELECTRIC PULSE TREATMENT ON MICROSTRUCTURE, ELECTROCHEMICAL AND DISCHARGE PROPERTIES OF AZ61 ANODES FOR Mg-AIR BATTERIES
Authors: Zou Jinchao , Zhang Tao , Huang Zhiquan , Zhao Chunjiang , Wang Junpeng
Published: January 2023

In this work, the effects of electric pulse treatment on the discharge and electrochemical properties of rolled and extruded AZ61 as anode of Mg-air battery were studied. The microstructure, electrochemical behavior and surface morphology after discharge were discussed to relate the discharge performance. The experimental results show that compared with the original magnesium anode (rolled and extruded), the magnesium anode treated by electric pulse has more negative corrosion potential, lower impedance value, higher discharge voltage and better specific energy. This is because electric pulse treatment can cause the coarse second phase in magnesium anode to dissolve and the grains to become more uniform. In particular, in the discharge process, the surface of magnesium anode after electric pulse treatment will form micro cracks, which is beneficial to promote the self-stripping of discharge products. It is worth noting that the effect of electric pulse treatment on rolled anode is better than that of extruded anode. It may be due to the different dislocation density in the two anodes. During the electric pulse treatment, the dislocation density in the alloy is highly correlated with the dissolution rate of β-Mg17Al12, which ultimately affects the volume fraction of the second phase in the alloy.

Authors: Christian Yuriko , Darmawan I Dewa Made Bayu Atmaja
Published: January 2023

Rindik is Balinese traditional music consisting of bamboo rods arranged horizontally and played by hitting the rods with a mallet-like tool called "panggul". In this study, the transcription of Rindik's music songs was carried out automatically using the Wavelet transformation method and spectral subtraction. Spectral subtraction method is used with iterative estimation and separation approaches. While the Wavelet transformation method is used by matching the segment Wavelet results with the Wavelet result references in the dataset. The results of the transcription were also synthesized again using the concatenative synthesis method. The data used is the hit of 1 Rindik rod and a combination of 2 Rindik rods that are hit simultaneously, and for testing the system, 4 Rindik songs are used. Each data was recorded 3 times. Several parameters are used for the Wavelet transformation method and spectral subtraction, which are the length of the frame for the Wavelet transformation method and the tolerance interval for frequency difference in spectral subtraction method. The test is done by measuring the accuracy of the transcription from the system within all Rindik song data. As a result, the Wavelet transformation method produces an average accuracy of 83.42% and the spectral subtraction method produces an average accuracy of 78.51% in transcription of Rindik songs.
Myers-Briggs Type Indicator Personality Model Classification in English Text using Convolutional Neural Network Method
Authors: Sugihdharma Joseph Ananda , Bachtiar Fitra Abdurrachman
Published: January 2023

Myers-Briggs Type Indicator (MBTI) is a personality model developed by Katharine Cooks Briggs and Isabel Briggs Myers in 1940. It displays a combination of preferences from four domains. Generally, test takers need to answer about 50 to 70 questions, and it is relatively expensive to know MBTI personality. The researcher developed a personality classification system using the Convolutional Neural Network (CNN) method and GloVe (Global Vectors for Word Representation) word embedding to solve this problem. The dataset used in this research consists of 8,675 data from the Kaggle site. The steps in this research are downloading the dataset from Kaggle, text preprocessing, GloVe weighting, classification using the CNN method, and evaluation using accuracy from the Confusion Matrix. Based on the tests carried out, using GloVe weighting can improve the model accuracy rather than random weighting. The best GloVe word dimensions depend on the metrics used to measure the model performance and the data of the classes contained in the dataset. From the CNN hyperparameter tuning test, the Adamax optimizer performs better and produces higher accuracy than the Adam optimizer. In addition, the CNN hyperparameter tuning increased model accuracy more significantly compared with the best GloVe word embedding dimensions.
Battling Against Environmental Crisis: Children in Action

Published: January 2023

With its historical privilege of the relationship between children and nature, children’s literature has long attended to ecological problems, often in concert with its attendant social problems. In a century of stories, from The Secret Garden (1911) to The Wizard of Earthsea (1968), The Iron Man (1968), The Iron Woman (1993), and The Marrow Thieves (2017), children’s authors have been demonstrating how children, prefiguring actual child activists such as Greta Thunberg, can lead the way towards solutions. Whether in literature or real life, it seems that it is the children who understand the urgency of environmental crises and can bring about responses. Children activists, such as Lucy, Hogarth, Frenchie and his companions, take decisive action in saving nature and the human world.
Psychological Trauma and Socio-Economic Burden of Girl-Child Marriage in Nigeria: Stephanie Linus’ ‘Dry’ as a Filmic Advocacy

The need to proffer solutions to the consequences of girl-child forced marriages in Nigeria has continued to draw scholarly attention within the ambits of sociology, history, law and human-right, women and gender studies, health, and psychology studies. However, studies examining the application of Nollywood films as advocacy texts in this regard are scarce. In response to this gap, this study examines interpretively Stephanie Linus’ ‘Dry’ as a filmic advocacy text, portraying the psychological trauma and the socio-economic burden of girl-child marriages in northern Nigeria. Our interpretive analyses utilize theories espousing how denial of childhood can become traumatic to the child-wives and eventually become a socio-economic burden to their family, community, and country. The key observation is that ‘Dry’ typifies a proper and efficacious utilization of film as an advocacy platform to interrogate and communicate matters relating to health and wellbeing revolving around girl-child forced marriages.

Published: January 2023

The study interrogated university students’ perception of suicide in a social system where self-murder is seen as a taboo yet constantly on the increase. In light of the difficulty expressed in studies on detecting risky behaviour, we focused on the influences of social factors on the perception of the normality and preventability of suicide. We administered a 47-item questionnaire to 490 students from five universities in Southeast Nigeria. Frequencies, percentages, Pearson’s bivariate correlation coefficient and multivariable binary logistic regression were used to analyze data. We found a significant positive but weak relationship between the perception of the normality of suicide and the perception of the preventability of suicide. The majority of the respondents did not show a tendency to suicide but ironically acknowledged that the high prevalence of risk factors such as depression were expected and normal. Place of residence, being seen as deeply religious, and the class of study had a significant impact on the perception of the normality and preventability of suicide. We discussed the implications of our findings on social integration among students.
Formation of Emotional Security of Students during the Period of Training in Conditions of Military Conflict
Authors:   V. G. Korolenko Poltava National University, Ukraine., Orlov Oleksii Petrovich
Published: January 2023

Ukrainian teachers and students are now in an extreme situation of military conflict when the territory of the country is under constant air fire, and the line of hostilities stretches for 1500 kilometres. The purpose of the article is to analyze the extreme learning conditions of Ukrainian students and develop a strategy for optimal emotional relaxation by selecting fiction for reading and deepening artistic perception. Respondents’ data (120 students and 53 pupils) were collected, systematized, evaluated, and analyzed using systematic written surveys (Project Tuning methodology) and statistical analysis methods. Testing corresponded to three stages of conflict development: conflict deployment, escalation, and post-conflict phase. Pedagogical activity mirrors this parable but in the opposite direction. Fiction thematically and genre-wise at each stage plays the role of a protective shield, which draws the line between students’ own emotions and the feelings of literary heroes. Perception of artistic texts was aimed at 1) identifying visual, auditory, and tactile associations; 2) olfactory sensations; 3) the ability to build associative chains; 4) imagining literary heroes; 5) emotionally immersing yourself in the world of fiction. Comparison of one’s own emotional perceptions with those that caused anti-utopian works and fantasy literature prove the effectiveness of the chosen pedagogical hypothesis.

The relevance of the present study follows from the necessity to establish parameterized cause-effect relationships that describe additional disease cases among population caused by chronic exposure to chemical factors. In this study, our aim was to explore relationships within the ‘environment – public health’ system to quantify and predict chronic risks under exposure to chemicals in ambient air. To achieve this, we collected statistical data on some municipalities located in the Russian Federation with different structures and levels of chemical pollution in ambient air. Data on population incidence and ambient air quality were coordinated at places where calculation points were located; these points were centers of residential buildings and their coordinates were applied in the study. Mathematical modeling of the relationships was conducted by using multiple linear regressions. Pollution indicators (chemical concentrations in ambient air) that met the requirements of biological plausibility and statistical significance of pair correlations were selected as independent variables. The obtained regression models contain 190 factors for 36 chemicals occurring in emission into ambient air from stationary and mobile sources, which allow calculating the frequency of additional disease cases for 29 diseases. The established factors make it possible to perform operative estimations of a number of diseases associated with ambient air quality at a place of residence relying on medical aid applications. The resulting relationships can be used to predict chronic health risks. Establishing criteria for ranking chemical health risks in zones influenced by hazardous chemical objects can become a next step in development of the suggested approaches.

Knee osteoarthrosis (OA) is a multifactorial disease with genetic factors playing an important part in its development. Our research goal was to examine associations between polymorphic variants rs1060105 and rs56116847 of SBNO1 gene, rs6499244 of NFAT5 gene and rs34195470 of WWP2 gene and developing stage 4 knee osteoarthrosis in people living in the Central Chernozem Region in Russia. Genotyping of polymorphic loci of candidate genes was accomplished in 95 patients with stage 4 knew osteoarthrosis and 500 people without the disease who were included into the reference group. We estimated associations between polymorphic loci of candidate genes and knee OA by using logistic linear regression within the allele, additive, recessive and dominant genetic models with gPLINK software. As a result, we replicated an association between a GWAS-significant rs6499244 polymorphism of NFAT5 gene and knee OA in people living in the Central Chernozem Region in Russia. An allele variant A of rs6499244 of NFAT5 gene was established to be “a risk factor” regarding stage 4 knee OA within the additive (OR = 1.61, рperm = 0.02) and recessive (OR = 2.07, рperm = 0.02) genetic models. The rs6499244 locus of NFAT5 gene is located in an area of DNAse I hypersensitivity; it increases DNA affinity to four transcription factors (CDP_6, RFX5_known1, RORalpha1_2, TCF4_known1); it is localized in functionally active promoters and enhancers; it is associated with expression of nine genes (CLEC18A, COG4, EXOSC6, NFAT5, NOB1, NPIPB14P, NQO1, PDXDC2P, SMG1P7) and alternative mRNA splicing of three genes (NOB1, NPIPB14P, NQO1) in various organs and tissues in the body including those that are pathogenetically significant for OA (fat tissue, tibial nerves and arteries, and skeletal muscles).
Moda e Decolonialidade: Colonialismo, vestuário e binarismo
Authors: De Oliveira Santos Heloísa Helena , Medrado Mi
Published: January 2023

Entendemos que o conceito Moda compõe, em seu espectro histórico-sociológico, categorias nascidas no seio da colonialidade do poder. A um só tempo, a noção de Moda associa capacidades intelectuais, produtivas, de cultura e espaço-tempo. Assim, perguntamos se há colonialismo nos primeiros textos sociológicos brasileiros que abordam a moda, notadamente em Gilberto Freyre e em Gilda de Mello e Souza. O objetivo deste trabalho é questionar como as diversas abordagens sobre o vestuário, desenvolvidas a partir da epistemologia do Eixo Norte, legitimam e produzem uma leitura que hierarquiza as relações de roupa, modos e moda, reproduzindo e divulgando a concepção de que o vestir das sociedades não-brancas está engessado ou é inferior. A proposta é problematizar o binarismo categórico da colonialidade Moda (desenvolvida) versus indumentária/traje (primitiva): este último relaciona os colonizados à ideia de tradição-cópia-indumentária, enquanto ao colonizador são associadas modernidade-inovação-moda. Nesta divisão, a moda europeia determina as categorias de classificação e relacionamento do vestuário no sistema-mundo, ao passo que, estabelece sua posição de hierarquia e poder no campo das decisões da moda, estabelecendo “A” forma de se relacionar e produzir. Desta maneira, como compreender as dinâmicas e as lacunas de silenciamentos e apagamentos que o projeto da modernidade impeliu como prática universal?  Como formular uma crítica radical à epistemologia colonial que opõe criação versus cópia?

A partir das disciplinas de Educação Inclusiva e Ensino de Língua Brasileira de Sinais (I e II), centrais ao núcleo das licenciaturas da Universidade Federal Latinoamericana UNILA, decidimos construir um modelo pedagógico em linha com o projecto político epistémico de integração e descolonização da América Latina. Este é um campo com fontes escassas e restritas. Concentramo-nos em fornecer algumas notas introdutórias baseadas nas fontes mais específicas e especializadas, bem como algumas notas críticas sobre a Educação na América Latina e no Sul Global. Num primeiro passo, fizemos um breve levantamento histórico da questão, para depois mostrar as relações existentes entre Escola e Colonialidade do Poder na experiência da Subjectividade Surda. Posterior, algumas considerações finais mais orientadas, para deixar em aberto questões e tarefas na construção de novos horizontes de racionalidade alternativa.
A escrita e o outro: dialogismo e formação do sujeito autor
Authors: Petrus Wilton , Santos Elian da Silva , Cavalcanti dos Santos Adriana , Gomes Yana Liss Soares
Published: January 2023

Este artigo teve como objetivo analisar um evento de produção textual no qual os sujeitos, em seu contexto de produção, puderam constituir o ato de reflexão de sua práxis tornando-se autores por intermédio da palavra própria e da palavra outra. Trata-se de uma pesquisa-ação (THIOLLENT, 2011) de abordagem qualitativa (BAUER; GASKEL, 2002). A partir dos pressupostos teóricos de Bakhtin (2010; 2011; 2017), Volóchinov (2017), entre outros, analisamos o desenvolvimento do texto dos alunos que aconteceu por intermédio do processo da mediação dialógica por uma oferta de contrapalavra (BAKHTIN, 2011; GERALDI, 2002). Os resultados indicam que, através da interação dialógica, o outro tem papel fundante na construção e enriquecimento do texto, colaborando na formação do sujeito autor e contribuindo para o desenvolvimento de eventos de narração mais detalhados através do uso de recursos linguísticos como densidade informacional e variedade lexical.
Identidade cultural do Brasil no seu interior sertanejo Euclides e Rosa
Authors: Magalhães Costa Gregory
Published: January 2023

O motivo civilizatório da literatura euclidiana culmina no Grande sertão de Guimarães Rosa. Em Euclides da Cunha, há um espelhamento entre primitivo e civilizado. A elite litorânea brasileira se considera civilizada e, desinformada pela manipulação midiática, considera seu interior sertanejo como bárbaro. Se a cidade vê o sertão como primitivo, o narrador-personagem simpatiza com a plural organização religiosa e social sertaneja e denuncia a tirania daqueles que se consideram modernos. Em Rosa, o sertão primitivo de Joca Ramiro e Hermógenes precisa lutar para manter sua cultura poética da terra mediante o ataque civilizatório de Zé Bebelo. O canto catártico de Riobaldo busca resgatar a intuição poética da humanidade e faz a mediação entre centro moderno e periferia simbólica.
Construções metadiscursivas constituintes do processo de referenciação em narrativas afiliadas ao lendário amazônico
Authors: Moura Heliud Luis Maia
Published: January 2023

O objetivo deste trabalho é apresentar o uso de construções metadiscursivas no processo de elaboração de narrativas afiliadas ao lendário amazônico. Tais construções residem em operações por meio das quais o narrador/produtor textual insere frequentemente, no seu discurso, formas verbais e sequências oracionais que remetem a outro narrador/locutor, a partir do que também implementa a atividade narrativa. Logo, enquanto recurso de textualização das mencionadas narrativas, esse tipo de construção se apresenta como uma estratégia de “reafirmação” do que já é dito, num determinado contexto sociodiscursivo, em relação a histórias de Boto, Cobra, Matinta Perera e Curupira. As citadas construções constituem também formas usadas pelo escritor (produtor) para implementar a progressão temática do texto. Na perspectiva textual-narrativa propriamente dita, configura-se como um artifício utilizado pelo narrador para dinamizar e dar mais consistência ao tópico em elaboração. Assim, no intercurso da atividade de narrar há uma interpelação a falas ou dizeres que passam a constituir o próprio processo narrativo, com um deslocamento recorrente para fatos, situações e eventos que se colocam como novos na estrutura referencial. O Corpus em análise constitui-se de dezessete narrativas referentes às entidades Boto, Cobra, Matinta Perera e Curupira. Tomo como referencial teórico as postulações de Jacqueline Authier (1981), Ingedore Grunfeld Villaça Koch (2004), Edviges Maria Morato (2005), Ingedore Grunfeld Villaça Koch e Vanda Maria Elias (2010), Clélia Spinardi Jubran (2005) e Heliud Luis Maia Moura (2013), para os quais a metadiscursividade reside na capacidade do produtor do texto de ter mais “acesso” ao que diz, podendo manipulá-lo de forma mais efetiva e consciente. No que trata dos processos referenciais, os procedimentos metadiscursivos servem para indicar o modo como o locutor textual “visualiza” os referentes gerados no interior do discurso, tomando posição acerca da forma como ele mesmo participa da atividade interacional.
O labor filológico e as humanidades digitais
Authors: Sampaio Holanda Maria Aurilene Pinto , Ximenes Expedito Eloísio
Published: January 2023

Pensar o fazer filológico sob a perspectiva das humanidades digitais é quebrar paradigmas de métodos e conceitos, visto que o ‘texto’ ganha novos usos, manuseios e intervenções por parte dos leitores/filólogos. Assim, as definições se ampliam, dando lugar a um novo objeto de investigação, que Paixão de Sousa (2009) denomina ‘texto digital’. Partindo deste princípio, objetivamos, neste trabalho, trazer a lume discussões teóricas, tendo como ponto de partida trabalhos científicos que versam sobre a interseção do campo filológico com as ferramentas digitais, assim, discutir a aproximação da filologia (SPINA, 1977; GUMBRECHT, 2003; XIMENES; 2013; FERREIRA, 2016) à perspectiva das humanidades digitais (PAIXÃO DE SOUSA, 2014). Tendo em vista que, o texto, como produto social e objeto de investigação da práxis filológica, interage e sofre pressão com as mudanças sociais, sobretudo as mudanças de cunho tecnológico, pois elas interferem diretamente na produção, no armazenamento e distribuição dos textos, pressupondo ao filólogo novos suportes e diferentes formas de manipulação e processamento da escrita. Assim, realizamos buscas, por meio de palavras-chave, em sites que portam em sua base de dados, trabalhos de cunho científico que discorrem sobre a temática aqui explorada. Elegemos o Portal de Periódicos da Capes e o Google Acadêmico, pela confiabilidade das informações armazenadas. Na busca, elegemos três trabalhos em língua portuguesa e de recente publicação. Na análise dos trabalhos, destacamos que a interseção do labor filológico com as humanidades digitais é um campo investigativo fértil, de positivas contribuições para o estudo da língua e da sociedade. Bem como, apontamos discussões que versam sobre a repercussão das ferramentas tecnológicas à materialidade textual sob a perspectiva das humanidades digitais. Por fim, destacamos a produtiva discussão acerca do fazer filológico sob a ótica das humanidades digitais, ampliando o debate sobre o acesso, a preservação e o manuseio de documentos que guardam histórias sociais e linguísticas.
Contextos referenciais em narrativas da amazônia: uma análise de anáforas indiretas
Authors: Moura Heliud Luis Maia
Published: January 2023

Este artigo objetiva analisar anáforas indiretas presentes em narrativas amazônicas, considerando que essas anáforas constroem processos referenciais i­­mersos no contexto em que tais narrativas são produzidas. As teorias que embasam este trabalho ancoram-se em Koch (2004; 2006; 2008); Marcuschi (2005; 2006; 2007); Schwartz (2000); Tesnière (1977); Tomasello (2003) e Moura (2013; 2017). As anáforas indiretas constituem atividades sociocognitivas e culturais, mobilizando-se processos como: anáforas indiretas (doravante AI) baseadas em relações semânticas inscritas nos SNs definidos e indefinidos; AI baseadas em papeis temáticos dos verbos; AI baseadas em elementos textuais ativados por nominalizações; AI baseadas em esquemas cognitivos e modelos mentais; AI baseadas em inferências ancoradas no modelo do mundo textual; AI sem antecedente cotextual, estando em jogo não somente estruturas textuais, mas também elementos imersos em contextos de referência. O corpus, em análise, relativo ao fenômeno em estudo, constitui-se de 5 (cinco) narrativas, constantes em 13 (treze) números da Revista Visagens, Assombrações e Encantamentos da Amazônia, de autoria de Monteiro (2000; 2002). Vale esclarecer que os números totais da revista foram editados entre os anos de 1997 a 2004, versando sobre: Boto, Cobra, Matintaperera, Curupira, Lobisomem e Assombrações e Visagens. As análises levam-me a concluir que os processos estudados são constitutivos dessas narrativas, reafirmando-se a premissa de que reconstroem significados simbólicos e sociocognitivos específicos.

Published: January 2023

Este artigo tem o objetivo de analisar a memória retomada na declaração do presidente Jair Messias Bolsonaro “Tem que deixar de ser um país de maricas”  (2020), referindo-se aos papéis de gênero e de sexualidade no enfrentamento à Covid-19 no Brasil.  A partir dos pressupostos teóricos inscritos na Análise do Discurso, inaugurada por Michel Pêcheux, tratamos dos efeitos de sentido produzidos a partir da afirmação da masculinidade normativa, como condição de superação da crise de saúde pública responsável pela morte de mais de 670 mil pessoas no Brasil. Interessa demonstrar de que maneira o dizer do presidente Bolsonaro  nega a ciência, ao tempo em que  precariza  e silencia gêneros dissidentes do padrão binário, num jogo de polarização  de sentidos autoritários.
As vogais médias pretônicas em Minas Gerais e em São Paulo: o Rio Grande como fronteira linguística
Authors: Magalhães José , Agreli Melo Campos Rosana
Published: January 2023

Este artigo tem como objetivo principal descrever a variação linguística nas margens sul e norte do Rio Grande, observando o comportamento das vogais médias pretônicas, a partir dos princípios da Sociolinguística Variacionista (LABOV (2008[1972]); WEINREICH, LABOV e HERZOG (2006[1968]). Para coleta de dados ao norte do Rio Grande, foram entrevistados 12 informantes de Uberaba, selecionados por amostragem aleatória estratificada. Para a região sul do Rio Grande, foram coletados dados de Igarapava, Franca e Ribeirão Preto, por entrevistas televisivas. Para lidar com o fenômeno, foram utilizadas a variáveis independentes linguísticas natureza da vogal alvo, altura da vogal tônica, distância entre vogal alvo e vogal tônica, e tipo do item lexical; e as extralinguísticas sexo, escolaridade, faixa etária, além da região geográfica para confrontar o sul e o norte do Rio Grande. Para as análises estatísticas, utilizou-se o software GoldVarbX. Os resultados apontaram que a vogal baixa /a/ na sílaba tônica não favorece o abaixamento da pretônica, ficando este gatilho a cargo de outra vogal média baixa. Confrontando os dados mineiros com os paulistas, constatou-se que, ao norte do Rio Grande, o abaixamento é categórico, com peso relativo 0.902; enquanto ao sul do Rio Grande o peso relativo é de apenas 0.015, revelando que o abaixamento da vogal pretônica não é a escolha dos paulistas. Depreende-se, pois, que o leito do Rio não demarca apenas uma fronteira geográfica, mas também uma linha divisória de natureza linguística, no que se refere à escolha do falante pela vogal pretônica como média baixa ou média alta.
Agarrando uma “minhocastanha”
Authors: Soares Motta Renata , Martinho Ferreira Maria Manuela
Published: January 2023

As sociedades urbanas ocidentais, separando a natureza da cultura, das crianças, da educação e da vida há séculos, instauraram uma dicotomia que persiste mesmo nas práxis e nas investigações que promovem o contato de crianças pequenas com o mundo “natural”. Dialogando com os estudos críticos da infância, novos materialismos, pós-humanismos e epistemologias ecológicas visamos contribuir para repensar “nossos” modos de ser/estar no mundo para além das tradições dicotômicas e compor um olhar acerca das crianças como seres enredados em várias naturezas-culturas. Com base em pesquisa etnográfica com crianças de um Jardim de infância privado ao “ar livre” em Portugal, analisa-se e discute-se como as crianças se relacionam com uma floresta e como esta se emaranha em suas brincadeiras. O engajamento das crianças e vidas mais-que-humanas – pássaros, pinheiros, castanhas – em modos de ser/estar coletivos, dá pistas para reposicionar as práticas educativas num mundo comum, heterogêneo e interdependente, valorizando um espírito de companheirismo e parentesco.
Astragaloside IV (ASIV) Mediates Endothelial Progenitor Cell (EPC)
Exosomal LINC01963 to Inhibit Pyroptosis and Oxidative Stress in
High Glucose-impaired Endothelial Cells
Authors: Xiong Wu , Zhang Xi , Zhou Jian-da , Tan Mei-xin , Liu Yu , Yan Yu , Lei Hua-Juan , Peng Jia-rui , Liu Wei , Tan Pei
Published: January 2023

Background:

Hyperglycemia is widespread in the world’s population, increasing
the risk of many diseases. This study aimed to explore the regulatory effect
and mechanism of astragaloside IV (ASIV)-mediated endothelial progenitor cells
(EPCs) exosomal LINC01963 in endothelial cells (HUVECs) impaired by high glucose.

Methods:

Morphologies of exosomes were observed by light microscope and electron
microscope. Immunofluorescence was used to identify EPCs and detect the expressions
of caspase-1. LINC01963 was detected by quantitative reverse transcription
PCR. NLRP3, ASC, and caspase-3 were detected by Western Blot. Nanoparticle tracking
analysis was carried out to analyze the exosome diameter. High-throughput sequencing
was applied to screen target lncRNAs. The proliferation of endothelial cells
was measured by cell counting kit-8 assay. The apoptosis level of HUVECs was detected
by flow cytometry and TdT-mediated dUTP Nick-End labeling. The levels of IL-
1β, IL-18, ROS, SOD, MDA, and LDH were measured by enzyme-linked immunosorbent
assay.

Results:

ASIV could promote the secretion of the EPC exosome. LINC01963 was
obtained by high-throughput sequencing. It was observed that high glucose could inhibit
the proliferation, reduce the level of SOD, the expression of NLRP3, ASC, and
caspase-1, increase the levels of IL-1β, IL-18, ROS, MDA, and LDH, and promote
apoptosis of HUVECs. Whereas LINC01963 could inhibit the apoptosis of HUVECs,
the increase the expression of NLRP3, ASC, and caspase-1, and decrease the levels
of IL-1β, IL-18, ROS, MDA, and LDH.

Conclusion:

EPCs exosomal LINC01963 play an inhibitory role in high glucoseinduced
pyroptosis and oxidative stress of HUVECs. This study provides new ideas
and directions for treating hyperglycemia and researching exosomal lncRNAs.

Authors: Hu Panpan , Zhai Shuheng , Liu Xiaoxie , Chu Hongling , Wei Feng
Published: January 2023

Background

Spinal metastases of lung cancer (SMLC) usually have a high degree of malignancy and require multimodality treatment. Patients with SMLC who experience clinical symptoms (eg, local pain, emerging or potential spinal instability, and progressive neurological dysfunction) require surgical treatment. However, there are discrepancies in the comparison of outcomes between surgical treatment and nonsurgical treatment.

Objective

This paper presents the protocol for a study that aims to compare the clinical outcomes of surgical treatment and nonsurgical treatment for SMLC, explore the prognostic factors of SMLC, and establish a survival prediction model based on these prognostic factors.

Methods

This is a prospective cohort study, with an anticipated sample size of 240 patients (120 patients in the surgical group and 120 patients in the nonsurgical group). We will collect baseline data, including demographic, clinical, and radiological information, as well as data from patient-reported questionnaires. Patients will be followed up at 3, 6, 12, and 24 months after treatment, and survival status will be assessed every 3 months. The primary outcome is the overall survival period. Prognostic factors associated with overall survival will be analyzed by univariate and multivariate Cox proportional hazards regression. Odds ratios with 95% CIs will be presented. Statistical significance is set at P<.05.

Results

This study has been approved by our institute’s Medical Science Research Ethics Committee (IRB00006761-M2021085) after a careful audit of the design and content. Patient enrollment began in June 2022 at our hospital. Data collection is expected to be completed by early 2026, and the study results will be published by mid-2027.

Conclusions

In this study, we propose to set up a prospective cohort of patients with SMLC to investigate the outcomes between surgical treatment and nonsurgical treatment. We will explore the role of surgical treatment in SMLC and provide guidance to peer surgeons.

A Medical Assistive Robot for Telehealth Care During the COVID-19 Pandemic: Development and Usability Study in an Isolation Ward
Authors: Wang Ruohan , Lv Honghao , Lu Zhangli , Huang Xiaoyan , Wu Haiteng , Xiong Junjie , Yang Geng
Published: January 2023

Background

The COVID-19 pandemic is affecting the mental and emotional well-being of patients, family members, and health care workers. Patients in the isolation ward may have psychological problems due to long-term hospitalization, the development of the epidemic, and the inability to see their families. A medical assistive robot (MAR), acting as an intermediary of communication, can be deployed to address these mental pressures.

Objective

CareDo, a MAR with telepresence and teleoperation functions, was developed in this work for remote health care. The aim of this study was to investigate its practical performance in the isolation ward during the pandemic.

Methods

Two systems were integrated into the CareDo robot. For the telepresence system, a web real-time communications solution is used for the multiuser chat system and a convolutional neural network is used for expression recognition. For the teleoperation system, an incremental motion mapping method is used for operating the robot remotely. A clinical trial of this system was conducted at First Affiliated Hospital, Zhejiang University.

Results

During the clinical trials, tasks such as video chatting, emotion detection, and medical supplies delivery were performed via the CareDo robot. Seven voice commands were set for performing system wakeup, video chatting, and system exiting. Durations from 1 to 3 seconds of common commands were set to improve voice command detection. The facial expression was recorded 152 times for a patient in 1 day for the psychological intervention. The recognition accuracy reached 95% and 92.8% for happy and neutral expressions, respectively.

Conclusions

Patients and health care workers can use this MAR in the isolation ward for telehealth care during the COVID-19 pandemic. This can be a useful approach to break the chains of virus transmission and can also be an effective way to conduct remote psychological intervention.
Mediating and Moderating Effects of Internet Use on Urban-Rural Disparities in Health Among Older Adults: Nationally Representative Cross-Sectional Survey in China (Preprint)
Authors: Liu Jing , Peng Junwei , Chen Minyan , Zhang Tao
Published: January 2023

BACKGROUND

The urban-rural disparities in health outcomes in China are remarkable. The internet has shown the potential to reduce the likelihood of contracting a disease by increasing disease knowledge. However, little is known about the effects of internet use in alleviating health inequities between urban and rural areas.

OBJECTIVE

This study aimed to examine the mediation and moderation of health disparities between urban and rural older adults through internet use.

METHODS

A total of 8223 respondents were selected from the China Health and Retirement Longitudinal Study 2018 data set. Basic activities of daily living, a brief Community Screening Instrument for Dementia, and the Centre for Epidemiologic Studies Depression Scale were used to measure functional disability, cognitive function, and depressive symptoms, respectively. Logistic regressions testing “internet use×urban-rural status” interactions for moderation and Karlson-Holm-Breen decomposition for mediation were performed.

RESULTS

Internet use moderated the urban-rural disparities in cognitive function (odds ratio 7.327, 95% CI 3.011-17.832) and depressive symptoms (odds ratio 1.070, 95% CI 1.037-1.787), but the moderating effects were significant only for those using the internet daily. Karlson-Holm-Breen results showed the suppression effects of using the internet daily (β=.012, 95% CI .002-.021) on the association between urban-rural status and cognitive function. The urban-rural inequality in depressive symptoms was partially attributed to the disparity in internet use (β=−.027, 95% CI −.043 to −.009).

CONCLUSIONS

The urban-rural inequalities in mental health are partially attributable to disparities in the prevalence of internet use between the 2 groups. However, using the internet is more beneficial for the psychological health of rural users, thereby alleviating the urban-rural disparities in health. Providing convenient channels for rural older adults to use the internet, improving the ability of rural users to effectively use the internet, and promoting internet popularity in rural areas are effective approaches to reducing urban-rural health inequalities.

Authors: Marri Shiva Shankar , Inamadar Arun C , Janagond Ajit B , Albadri Warood
Published: January 2023

BACKGROUND

Artificial intelligence (AI) aims to create programs that reproduce human cognition and processes involved in interpreting complex data. Dermatology relies on morphological features and is ideal for applying AI image recognition for assisted diagnosis. Tibot is an AI app that analyzes skin conditions and works on the principle of a convolutional neural network. Appropriate research analyzing the accuracy of such apps is necessary.

OBJECTIVE

This study aims to analyze the predictability of the Tibot AI app in the identification of dermatological diseases as compared to a dermatologist.

METHODS

This is a cross-sectional study. After taking informed consent, photographs of lesions of patients with different skin conditions were uploaded to the app. In every condition, the AI predicted three diagnoses based on probability, and these were compared with that by a dermatologist. The ability of the AI app to predict the actual diagnosis in the top one and top three anticipated diagnoses (prediction accuracy) was used to evaluate the app’s effectiveness. Sensitivity, specificity, and positive predictive value were also used to assess the app’s performance. Chi-square test was used to contrast categorical variables. P<.05 was considered statistically significant.

RESULTS

A total of 600 patients were included. Clinical conditions included alopecia, acne, eczema, immunological disorders, pigmentary disorders, psoriasis, infestation, tumors, and infections. In the anticipated top three diagnoses, the app’s mean prediction accuracy was 96.1% (95% CI 94.3%-97.5%), while for the exact diagnosis, it was 80.6% (95% CI 77.2%-83.7%). The prediction accuracy (top one) for alopecia, acne, pigmentary disorders, and fungal infections was 97.7%, 91.7%, 88.5%, and 82.9%, respectively. Prediction accuracy (top three) for alopecia, eczema, and tumors was 100%. The sensitivity and specificity of the app were 97% (95% CI 95%-98%) and 98% (95% CI 98%-99%), respectively. There is a statistically significant association between clinical and AI-predicted diagnoses in all conditions (P<.001).

CONCLUSIONS

The AI app has shown promising results in diagnosing various dermatological conditions, and there is great potential for practical applicability.
Photosynthetic efficiency in species with C3 and C4 metabolisms
Authors: Neto Benjamim Pereira da Costa
Published: January 2023

Beans and corn are very important crops in terms of human nutrition worldwide, however each of them has its particularities, especially in the characteristics of photosynthetic metabolism (energy production), which are C3 and C4, respectively. According to studies in the field of physiology of higher plants, the C4 metabolism is an evolution of the C3 metabolism, being, according to the literature, more efficient from the photosynthetic point of view. The present work was based on the following question: In fact, is C4 metabolism more efficient than C3 from the point of view of energy production?. Thus, this work aimed to quantify and compare the photosynthetic potential of species with C3 and C4 metabolisms. The results of this study, therefore, pointed to C3 metabolism as the major energy producer in the photosynthetic process. On the other hand, it considered that the relationship between the energy produced and the energy stored in grains was higher in the C4 metabolism culture, that can change from species to species.

Published: January 2023

Este estudo objetivou analisar o quantitativo e tipos de Resíduos de Serviços de Saúde (RSS) gerados em uma instituição hospitalar à época do início da implantação do Plano de Gerenciamento de Resíduos de Serviços de Saúde (PGRSS) (2013), comparando com os dados de geração dos dias atuais (2020). Visando assim, discutir potencialidades e desafios inerentes à sua estruturação nos serviços, identificar alterações sazonais ou mesmo correlacionadas à pandemia da Covid-19. Trata-se de um estudo descritivo e exploratório, de natureza quantitativa. Os dados foram obtidos em planilhas do PGRSS da instituição, contendo registros diários da pesagem dos RSS. Os dados sugerem uma influência positiva da implantação do PGRSS na redução de resíduos vez que, embora tenha se observado o aumento do quantitativo de resíduos infectantes e químicos, identificou-se a redução dos resíduos comuns, sugerindo melhorias na segregação dos resíduos potencialmente contaminados e que remetem ao maior risco para a saúde coletiva e o meio ambiente.
