Authors: Erdas-Kartal Eda , Ada Ezgi
Published: May 2022

This study is a case study that investigates the perceptions of preschool children about the causes, consequences, and solutions to environmental problems. A total of 41 children participated in the study. The data were obtained by using the draw and explain the technique, which included 3 different drawings and telling the children about the causes, consequences, and solutions of environmental problems. In the analysis of the data, the content analysis method was used. As a result of the research, it was found that the preschool children's perceptions were limited; however, as the age group grows, it has been determined that the icons used in the pictures related to the causes, consequences, and solutions of the environmental problems vary. It was revealed that the children associate the causes and consequences of environmental problems with pollution and the ways of solving environmental problems with the prevention/elimination of this pollution. It has been observed that the number of children related to the destruction of nature and irresponsible consumption of natural resources with environmental problems is very limited. In order to improve children's perceptions of environmental problems, it is suggested that teachers and parents should give more space to activities and games related to the environment in daily flow.

The Impact of Private Entrepreneur’s Religious Beliefs and Political Identity on the Corporate Philanthropy Donations
Authors: Zhang Leilei
Published: May 2022

Corporate philanthropy donations act as one of the important ways for enterprises to fulfill their social responsibilities. There are many factors that influence corporate charitable donations, and one of which is the entrepreneur's personal characteristics. This study discusses the influence of private entrepreneurs’ religious beliefs on corporate philanthropy, and further analyzes the regulating effect of entrepreneurs’ political identity on religious beliefs and corporate philanthropy. Through face-to-face in-depth interviews with 11 charitable entrepreneurs in 11 cities of 10 provinces in China, applying continuous analytic induction, combined with NVIVO software for three-level coding, it can be concluded that the religious beliefs of private entrepreneurs have no absolute effect on corporate philanthropy, but entrepreneurs with religious beliefs are all keen on philanthropy; and their political identities of having a positive impact on corporate philanthropy. For entrepreneurs without political identities, their religious beliefs have a positive impact on corporate philanthropy, while for entrepreneurs with political identities, there is a stronger positive correlation between their religious beliefs and corporate philanthropy. The research results help to further understand the motivation for charitable donations of private enterprises, and play a practical guiding role in promoting the development of private corporate philanthropy.

Published: May 2022

The current research aimed to 1) identify the pronunciation abilities of EFL tertiary students at Rajamangala University of Technology Lanna Phitsanulok (RMUTL PLC) according to their self-evaluation, 2) reveal the English pronunciation learning strategies employed among EFL tertiary students with different self-evaluated pronunciation abilities, and 3) investigate whether there is any different employment of the English pronunciation learning strategies among the EFL tertiary students with different English pronunciation abilities. The participants were 270 EFL students enrolling in the second semester of the Academic Year 2019. Of the 270 participants, 40 participants anonymously and voluntarily took part in the semi-structured interviews. The data for analyses were obtained through the questionnaire and the semi-structured interviews. The quantitative data were statistically analyzed, and the qualitative data were scrutinized using the thematic analysis method. The results showed that, of the three pronunciation ability groups, namely good (GG), moderate (MG), and low (LG) groups, most of the EFL tertiary students at RMUTL PLC evaluated themselves as having a moderate English pronunciation ability. The GG participants employed the cognitive pronunciation learning strategy most often, while the MG and LG used the affective and social pronunciation learning strategies most often. Accordingly, the divergent employment of pronunciation learning strategies exists among these EFL tertiary students with diverse pronunciation abilities. They relied on online applications, such as Google Translate, for pronunciation demonstration because of its convenience and ease to access. When the participants did not use an online application, they sought help from their classmates rather than asking the teachers owing to their proximity and intimacy.

Sistema Hidráulico para el Beneficio del pueblo de Tochimilco durante el siglo xvi
Authors: Toral Echegaray Luis Fernando
Published: May 2022

Este artículo tiene el objetivo de explicar los beneficios que tuvo una comunidad al poseer diversas fuentes de abastecimiento de agua. Estos privilegios repercutieron particularmente en la historia y conformación del pueblo de Tochimilco durante los primeros años virreinales, y trascendieron favorablemente en soluciones constructivas encargadas de captar, conducir, distribuir o almacenar el agua para el gozo de sus pobladores. Además, los frailes franciscanos, al ser uno de los principales beneficiarios del vital recurso, implementaron sistemas hidráulicos con el objetivo de suministrar de agua a su convento. Esta investigación surge por el interés de comprender arquitectónicamente los aspectos tecnológicos y las soluciones constructivas que surgieron en los pueblos de doctrina para el óptimo aprovechamiento de agua. Estos matices fueron indispensables en el pueblo de Tochimilco para su desarrollo agrícola, estabilidad social y ecuanimidad en los repartimientos de agua desde el siglo xvi.
A Transcendental and Eco-critical Reading of Sunil Sharma’s Political Novel The Minotaur
Authors: Sangeeta Sharma
Published: May 2022

Sunil Sharma is in the vanguard of the contemporary fiction written in Indian English today. He has an enormous output of short fiction and poetry as well. Basically, a Marxist-text, but multi-layered, scholars are finding his novel highly relevant to assess the power -and wealth-driven modern societies. His debut novel, The Minotaur, is a master narrative that depicts the struggling humankind, groping for intellectual answers to old existential problems of the inequity of wealth and power, justice and good governance, and, oppression of the liberals. In short, the enduring human desires for a more humane, better, fair and liveable world for everybody. The novel is divided into an epilogue, eight chapters and an afterword. The most astonishing fact is the vision of the writer towards nature and its treatment at his hands. He has found nature to be a source of profound meaning, tranquillity and knowledge. Today, when there is a revived interest and lot of discussion over the reclamation of nature from mindless exploitation by man, it can be discerned that the writer in the very first decade of the twentieth century has posited wilderness with serenity, beauty, mysticism and spirituality. Nature has been delineated as life-giving and as a timeless marvel. The current paper deals with the transcendental and eco critical reading of this seminal text. It is an attempt to analyse and trace the writer’s oblique but remarkable portrayal of the virtues manifested in nature.
Tracing the Absent-Present Gandhi in Raja Rao’s Kanthapura
Authors: Shalini Kaushik
Published: May 2022

The paper tries to analyse the role of Gandhi in the nationalist movement which can be witnessed in the novel Kanthapura. The figure of Gandhi is not present in the text as one of the characters (apart from the interaction which Moorthy tells about that he had with Mahatma) but the whole narrative revolves around him. It is through media and Moorthy that women in the text get to know Gandhi and they are all united in spirit though they have never met Gandhi in person. This paper also tries to explore that how Gandhi challenges, contests, and redefines masculinity and femininity, thus blurring the lines between genders. The binaries of pure and impure, the issue of caste are examined and a new meaning to pilgrimage has been given. The political thinking of Gandhi seems to transform traditional meanings and one gets an alternative vocabulary of “home”’ and “masculinity”.
FORMAÇÃO CRÍTICA DOCENTE EM TEMPOS DE ESCOLA SEM PARTIDO
Authors: Yamauchi Cyntia Regina de Oliveira
Published: May 2022

O presente ensaio de análise teve como objetivo central traçar um diálogo entre os fundamentos bakhtinianos e freireanos na formação crítica docente e, sobre esse constructo, discorrer sobre a filosofia do ato ético, do Círculo de Bakhtin e sobre os conceitos de Paulo Freire que pressupõe a Educação como práxis geradora de autonomia, conscientização e libertação. Esse percurso se mostrou necessário para demonstrar a inconstitucionalidade do Movimento Escola Sem Partido. O posicionamento pela proibição do discurso ideológico no contexto educacional tem como pano de fundo a doutrinação ideológica, que visa um único e exclusivo ponto de partida. Isso porque banindo a capacidade de ação dos sujeitos de protagonizarem o seu processo educativo, também almeja-se dizimar a consciência e capacidade de ação política na vida cotidiana. Outrossim, a censura do debate político e a negação do cunho ideológico da educação detém perigoso fundo político, que é disfarçado de apartidário e destituído de ideologia. Por isso, ao romper com os pressupostos conservadores, no qual pressupõe que o professor é o detentor do saber, inauguramos outra postura docente. Àquela em que o educador é o problematizador, o mediador dos conteúdos, aquele que vai instigar e inquietar os discentes e não o dissertador.
ENSINO A DISTÂNCIA: A EDUCAÇÃO COMO FORMA DE ESPETÁCULO
Authors: Yamauchi Cyntia Regina de Oliveira
Published: May 2022

Pretende-se com este artigo abordar aspectos teóricos que norteiam a modalidade de Ensino a Distância e analisar de forma crítica como a espetacularização e comercialização desse modelo de ensino pode sustentar a ideia de que essa modalidade pode ser garantia de sucesso e empregabilidade. Seguindo nesta acepção, almejamos falar de estudantes reais em busca de uma educação real. A questão específica que se intensifica e, evidentemente, é geradora da inquietação para o tema se concentra em pensar: como a rápida comercialização da educação, baseada na tecnologia, pode mercantilizar o sistema de ensino e, em contra partida, espetacularizar o consumo? Observando o panorama que temos no referido tema, mostra-se como sendo de caráter emergencial pensar sobre esse contexto de maneira próxima, realista e interventiva.
USO DE PROBIÓTICOS NO TRATAMENTO DA DERMATITE ATÓPICA: UMA REVISÃO INTEGRATIVA
Authors: Belmont Eloah Jacinta , Egypto Lívio e Vasconcelos do
Published: May 2022

INTRODUÇÃO. A Dermatite Atópica (DA) ou eczema atópico é uma patologia de caráter recidivante e crônico, acometendo pele e atingindo todas as faixas etárias, porém com prevalência importante de 25% na população infantil. Dentre os tratamentos emergentes para a DA, destaca-se o uso oral de probióticos, mostrando a eficácia sobre o desenvolvimento da microbiota humana residual. OBJETIVO. Analisar os efeitos do uso dos probióticos no tratamento da dermatite atópica, visando uma melhor estabilidade e qualidade de vida para os acometidos. MÉTODOS.  Revisão Integrativa da Literatura para a sintetização dos principais resultados dos estudos encontrados nas principais bases de dados virtuais entre 2018 e 2021. RESULTADOS E DISCUSSÃO. Foi elucidado que a aplicação tópica de probióticos resultou em uma melhora dos sintomas da DA por meio de um maior estímulo à imunidade inata e um controle maior da colonização por S. aureus. Entretanto, extem outros artigos que refutam os efeitos dessas drogas, afirmando que não houve diferença significativa à essa terapêutica, sugerindo uma heterogeneidade dos resultados deste modo de tratamento. CONCLUSÃO. A aplicação desse tipo de terapia trouxe resultados explícitos por meio da diminuição do índice SCORAD e melhora dos índices de recidiva da doença, qualificando-os como possíveis alternativas tanto nos períodos de doença ativa e como forma de prevenção. Contudo, fazem-se necessários novos estudos com maior nível de evidência e maior número de participantes envolvidos, em busca de maior comprovatividade da atuação dessa medicação na doença.

Anestesia para cesariana em paciente com linfangioleiomiomatos
Authors: Cavalcante Rodrigues Andresa , Marques dos Santos Neto Jayme , Leite Fernandes Raphaella Amanda Maria , Ananias da Silva Neto Manoel
Published: May 2022

Introdução: A linfangioleiomiomatose (LAM) é uma doença rara de etiologia desconhecida, classicamente descrita em mulheres em idade reprodutiva e, ocasionalmente, na pós-menopausa. A gestação nestas pacientes é de alto risco, pois as alterações fisiológicas somam-se às da LAM, agravando o status cardiorrespiratório materno. Relato de Caso: Gestante, 29 anos, portadora de LAM e glomeruloesclerose segmentar e focal (GESF) colapsante diagnosticadas há 2 anos, teve indicação de interrupção da gestação no curso da 35ª semana por piora da função renal. Espirometria revelou importante distúrbio restritivo. Internada no curso da 34ª semana de gestação submeteu-se a corticoterapia para a maturação pulmonar fetal, quando apresentou piora da função renal e foi indicada a cesárea. Optou-se pela anestesia regional combinada. Comentários: A prevalência da LAM em mulheres varia de 1 a 2,6:1.000.000 de mulheres. Surge associada à Esclerose Tuberosa ou de forma idiopática. No caso, adotou-se a anestesia regional combinada, em virtude da dificuldade no manejo da via aérea na gestante. Fatores hormonais parecem ter papel na iniciação e progressão da LAM.

Introdução: Metástases oculares são subnotificadas e, adicionalmente, algumas apresentações são menos frequentes, devendo ser rastreadas de forma interdisciplinar. Relato de caso: Trata-se de mulher de 59 anos, branca, com história pregressa de câncer de mama unilateral, onde sintomas e sinais oftalmológicos foram as manifestações que levaram ao diagnóstico de recidiva da doença por metástase ocular após seis anos de tratamento. Comentários: Devido a possível apresentação assintomática das lesões, localização e ausência de protocolo de rastreamento para metástases oculares em doenças oncológicas, muitos casos de tumores metastáticos intraoculares não são diagnosticados. Após período considerado livre da doença, as queixas da paciente serviram de estímulo para avaliação oftalmológica, embora, muitos tumores intraoculares avançados podem ser assintomáticos, o que contribui para maior morbidade ocular. Sítios raros de metástase ocular pode ser fator preditor de gravidade da doença.

Purpose: To review the existing evidence in 2017-2018 and spreading the information, with solid scientific basis, regarding the use of no operative treatment for children with uncomplicated acute appendicitis. Methods: A literature search for the years 2017/2018 was performed using the following descriptors: uncomplicated acute appendicitis, children, paediatric appendicitis, pediatric appendicitis, management, medical treatment, clinical treatment, antibiotics treatment, no operative treatment and surgical treatment, appendectomy. Randomized controlled trials were considered the best source of information. Results: On the reviewed literature, one can say that the no operative approach for uncomplicated acute appendicitis in children presents similar outcome, hospital length of stay, antibiotic days, reduced degree and duration of pain, and overall perioperative complication rates, but there may be more inpatient readmissions and missing other diseases when compared with surgical treatment. However, this new approach reduces negative appendectomy rate, shorter days of sick leave and care leave, expedited return for the child go back to school and other normal activities, decreased hospital charge and less long term complications. Conclusion: Antibiotics treatment alone appears to be a safe first-line therapy in selected children with uncomplicated acute appendicitis and deserves a randomized controlled trial in tertiary hospitals in Brazil. Those patients who require future appendectomy do not experience significant complications. A multicenter Brazilian trial comparing antibiotics-first to appendectomy, including outpatient management, is feasible to evaluate efficacy and safety of this new approach.

Published: May 2022

Objetivo: Analisar a sobrecarga e qualidade de vida percebida por cuidadores, correlacionando-as com o grau de deﬁciência dos indivíduos com acidente vascular cerebral crônico e seu comprometimento nas atividades de vida diária. Métodos: Estudo transversal e analítico desenvolvido no Centro Especializado em Reabilitação CER IV-IMIP (Recife – PE). Foram avaliados trinta e oito cuidadores primários informais, quanto à sobrecarga e qualidade de vida após a avaliação de seus respectivos pacientes, quanto a sua funcionalidade ou incapacidade. Foi considerado paciente pós Acidente Vascular Cerebral (AVC) crônico, com mais de 6 meses de lesão. Os seguintes instrumentos foram utilizados: CIF - classiﬁcação internacional da funcionalidade; QASCI - avaliação da sobrecarga do cuidador informal, e WHOQOL- bref - avaliação da qualidade de vida. As análises estatísticas foram feitas com o teste Shapiro-Wilk com p<0,05 (SPSS). Resultados: Foram avaliados 38 cuidadores primários informais, os quais, em sua maioria, relataram 'sobrecarga intensa' (média de 102,92). Em relação à qualidade de vida, a maioria encontra-se entre 'necessita melhorar' e 'regular'. Houve correlação positiva signiﬁcativa, expressando relação direta entre a sobrecarga do cuidador e o item 'função do corpo'. Conclusão: cuidadores de pacientes vítimas de AVC que apresentam deﬁciências, relatam sobrecarga de trabalho e interferência na sua qualidade de vida.

Published: May 2022

Introdução: A infecção do trato respiratório é responsável por elevada morbimortalidade, além de levar ao uso frequente de antibióticos. É importante o conhecimento do perfil bacteriológico de acordo com o local avaliado e a doença de base do paciente, uma vez que, em muitas ocasiões, o tratamento dessas infecções é iniciado empiricamente. Objetivo: Identificar o perfil bacteriológico das culturas de escarro e dos lavados broncoalveolares e verificar a doença pulmonar de base dos pacientes internados na enfermaria de Pneumologia de um Hospital Terciário referência em doenças pulmonares do estado de Pernambuco. Métodos: O estudo consistiu de uma série de casos retrospectiva, onde foram analisadas as culturas de escarro e/ou do lavado broncoalveolar de 70 pacientes. Resultados: Os patógenos mais prevalentes nas culturas de escarro foram a Pseudomonas sp. e a Klebsiella sp., presentes, respectivamente, em 17 (24%) e 15 (21%) pacientes. Não houve predomínio de qualquer patógeno nas culturas dos lavados broncoalveolares. A doença pulmonar de base mais prevalente foi a bronquiectasia por sequela de tuberculose pulmonar, havendo relação significativa entre a sua presença e a infecção por Pseudomonas sp. (P < 0,05). Conclusão: O encontro de Pseudomonas sp. como a bactéria mais prevalente, principalmente em pacientes que apresentam bronquiectasia por sequela de tuberculose pulmonar, assim como o achado de Klebsiella sp. como o segundo patógeno mais frequente, ainda que não associado a alguma doença pulmonar de base, poderão auxiliar na escolha da terapia empírica de pacientes internados na enfermaria de Pneumologia de um Hospital Terciário de Referência em doenças pulmonares.

Published: May 2022

Objetivos: Identificar nos artigos revisados a FIO no intraoperatório e pós-operatório ideal para reduzir a incidência de ISC. Métodos: Desenvolveu-se uma revisão sistemática da literatura, com busca nas bases de dados: LILACS, PUBMED e SCIELO para responder a seguinte questão norteadora: Correlação da FiO no intraoperatório e pós-operatório imediato com a menor incidência de ISC. Resultados: Na avaliação dos  artigos estudados, não comprovaram relevante melhoria na ISC após a utilização de altas FiO. Porém, estudos evidenciaram menor incidência  desta infecção nos pacientes que receberam altas concentração de oxigênio suplementar no intraoperatório e pósoperatório. Conclusão: Existe correlação entre o aumento da FIO no intraoperatório e pós-operatório com a menor  incidência de ISC. Entretanto, diante da pequena quantidade de estudos disponíveis na literatura, da heterogeneidade das populações e dos procedimentos cirúrgicos conclui-se que são necessárias mais pesquisa.

Introdução: As plantas alimentícias não convencionais (PANC) destacam-se como plantas que possuem umaou mais partes comestíveis, sendo elas espontâneas ou cultivadas, nativas ou exóticas que não estão incluídas em nossocardápio cotidiano. Este trabalho visa abordar as plantas alimentícias não convencionais Objetivo: como alimentofuncional para a população, de forma a promover a disseminação do conhecimento dessas espécies na cultura alimentar e oincentivo ao seu consumo. Métodos: Foram sumarizados dados de 30 artigos recentes em português e inglês provenientesde bases de dados (Scielo e Pubmed), cadernos de saúde e livros. Comentários: As PANC estudadas demonstraram atuarnos mais diversos processos metabólicos, apresentando atividades anti-inflamatórias, antibacterianas, cicatrizantes,antineoplásicas e antiescorbúticas. Além disso, constatou-se a presença de concentrações significativas de cálcio, ferro,zinco, potássio e magnésio em suas composições. Aliado a isso, tem-se o alto teor de proteínas e de fibras, servindo noauxílio de processos gastrointestinais. Conclusão: As plantas alimentícias não convencionais ainda são pouco conhecidaspela população brasileira. Suas composições e valores nutricionais já são bem conhecidos, bem como a segurança de seuemprego na alimentação diária. Além de sabor agradável, elas possuem altas concentrações de fibras, vitaminais eminerais, necessários na manutenção da homeostase corporal.
Efeitos da desprescrição de inibidores de bomba de prótons
Authors: Martins de Paula da Mota Silveira Rebeca , Menezes de Melo Fábio
Published: May 2022

Introdução: Entre os medicamentos mais prescritos mundialmente encontram-se os inibidores da bomba deprótons (IBP), que apresentam bastante utilidade no tratamento de doenças gástricas e eficácia pela sua baixa toxicidade ebloqueio da secreção gástrica. Apesar da sua utilidade durante o tratamento, o uso prolongado destes medicamentos podecausar sérias complicações e prejuízos para o paciente que faz uso contínuo desses fármacos. Com o intuito de diminuir adose ou interromper o uso de medicamentos que possam trazer danos, tem-se investido muito na desprescrição de IBP, quedeve ser realizada de modo a considerar os benefícios, a finalidade do tratamento, a comodidade, a idade e também acooperação do paciente. Realizar uma revisão de literatura a respeito dos efeitos negativos Objetivo: e positivos dadesprescrição dos inibidores de bomba de prótons. Métodos: Revisão narrativa a respeito da desprescrição do IBPrealizada na Biblioteca Virtual de Saúde (BVS) e nos bancos de dados SCIELO, LILACS, usando os descritores:desprescrição, toxicidade, ácido gástrico e esofagite. Foram selecionados 15 artigos publicados nos últimos 12 anos queenvolviam os três núcleos temáticos: Ação dos inibidores de bomba de protóns sob a secreção gástrica, complicações pelouso prolongado de IBP e a importância da desprescrição dos IBPs. Resultados: Sabe-se que vários pacientes acabamautomedicando-se ou dando continuidade a tratamentos anteriores sem o conhecimento médico; além disso, o uso demuitos fármacos juntos sem uma análise prévia para a patologia pode ocasionar várias complicações. Desse modo, adesprescrição desses medicamentos, especialmente dos IBPs, é uma das maneiras de impedir efeitos indesejados,doençasno pacientee até mesmo complicações de doenças pré-existentes. A importância da desprescrição é evitar que IBPs sejamprescritos por tempo indeterminado e também garantir a segurança do paciente evitando sua exposição a riscos inerentesde reações adversas, erros de medicação, interações medicamentosas e internações em decorrência de complicações para omesmo. Conclusão: Nesse sentido, embora sejam potentes para as doenças gástricas, os IBPs são desnecessários paraalgumas doenças digestivas, daí a importância de uma equipe multidisciplinar para tratar o paciente e reduzir a prescriçãodestes IBPs. Concluímos que para realizar a desprescrição é preciso, então, escolher o tratamento que tenha umaabordagem geral e que traga menos prejuízo à saúde e à vida do paciente.

Objetivo: verificar e comparar a toxicidade aguda de extratos das folhas (Ppf) e do caule (Ppc) de Pimenta pseudocaryophyllum em Artemia salina. Métodos: Os extratos Ppf e Ppc, nas concentrações de 1, 10, 100 e 1000 μg/ mL, foram utilizados nos ensaios de toxicidade aguda utilizando o microcrustáceo Artemiasalina, incubados por um período de 24 e 48 horas, realizados em triplicata. O número de náuplios mortos foram quantificados e a CL50 foram calculadas por regressão nãolinear. Resultados: o extrato Ppc apresentou toxicidade apenas em 48hs (CL50 = 140,2 ± 76,7 μg/mL), considerada moderada. Já o extrato Ppf foi tóxico tanto na exposição por 24hs (CL50 = 372,0 ± 58,1 μg/mL), quanto por 48hs (CL50 = 0,8 ± 0,1 μg/mL), apresentando toxicidade moderada e alta, respectivamente. Conclusão: caule e folhas de P. pseudocaryophyllum possuem metabólitos ativos que levam toxicidade a Artemia salina,que provavelmente são substâncias diferentes ou estão mais concentrados nas folhas.
