Abstract Introduction: The HaDQ is an alternative to conventional hospitalization for clinically stable surgical patients who require complex nursing procedures due to intensity, frequency or characteristics, and control by a surgical specialist at home. Method: Cross-sectional, descriptive and retrospective study of the HADQ activity of our hospital during the first six months of 2020, to analyze the impact of the SARSCov2 pandemic in the unit. Three periods are distinguished: pre-pandemic (Jan-Feb), lockdown (Mar-Apr), post-lockdown (May-Jun). Two groups are differentiated: A (conventional HaD) and B (COVID19 preoperative screening). Various variables were collected: month, type, stay (HaD and hospital), procedures, readmissions, address, type of visits, covid+. A quantitative and qualitative descriptive statistical analysis of the results obtained was carried out. Results: 345 patients were admitted, 225 in group A (phase Pre (34%), Phase C (40%), and phase Post (25%)), and 120 in group B (Phase C (75%), phase Post (25%)). %)). The confinement (phase C) was the most active period of the HADQ, both due to the number of admissions (53%), and the complexity of group A, which required more procedures (71%) and more home visits (52%). There was also an increase in patients from the non-coverage area (42%), which involved medical and nursing visits at the Day Hospital (HD) (21%), and an increase in medical telephone consultations (36%). In the phase Post, the income of group A decreased by 37%. Conclusions: The HaDQ was reorganized due to the pandemic to care for more surgical patients, being an essential care resource, especially during confinement.

Resumen Introducción: La hospitalización a domicilio para pacientes quirúrgicos (HaDQ) es una alternativa a la hospitalización convencional para pacientes quirúrgicos estables clínicamente, que precisen procedimientos de enfermería complejos por intensidad, frecuencia o características, y control por especialista quirúrgico en el domicilio. Método: Estudio transversal, descriptivo y retrospectivo de la actividad de la HADQ de nuestro hospital durante los primeros seis meses del 2020, para analizar la repercusión de la pandemia por SARS-CoV-2 en la unidad. Se distinguen tres periodos: prepandemia (enero-febreo), confinamiento (marzo-abril), posconfinamiento (mayo-junio). Se diferencian dos grupos: A (HaD convencional) y B (despistaje preoperatorio COVID19). Se recogieron diversas variables: mes, tipo, estancia (HaD y hospital), procedimientos, reingresos, domicilio, tipo visitas, COVID+. Se realizó un análisis estadístico descriptivo cuantitativo y cualitativo de los resultados obtenidos Resultados: Ingresaron 345 pacientes, 225 en el grupo A (fase Pre (34%), fase C (40%), y fase Pos (25%)), y 120 en el B (fase C (75%), fase Pos (25%)). El confinamiento (fase C) fue el período más activo de la HADQ, tanto por número de ingresos (53%), como por la complejidad del grupo A que requería más procedimientos (71%) y más visitas domiciliarias (52%). También aumentaron los pacientes de zona de no cobertura (42%), que implicaron visitas médicas y de enfermería en Hospital de Día (HD) (21%), y aumento de consultas telefónicas médicas (36%). En la fase Pos disminuyeron un 37% los ingresos del grupo A. Conclusiones: La HaDQ se reorganizó por la pandemia para atender a más pacientes quirúrgicos, siendo un recurso asistencial esencial, especialmente durante el confinamiento.

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. 19191987 1919 1987 (1919-1987 Auschwitz genres whole scienceart art when experiences camp. camp . camp) Levis s writings mans man article questions substances 1919198 191 198 (1919-198 191919 19 (1919-19 19191 1 (1919-1 (1919- (1919 (191 (19 (1 (

RESUMO Objetivo: Avaliar o perfil de idade e antropometria dos pacientes com diagnóstico de fratura do fêmur proximal em idosos admitidos em um hospital filantrópico de São Paulo. Métodos: Estudo retrospectivo, observacional, transversal. Foram incluídos todos os pacientes com fratura do fêmur proximal e idade superior a 59 anos, internados em um hospital filantrópico de São Paulo entre janeiro de 2019 e abril de 2020. A análise dos 85 prontuários levantados resultou na coleta de dados antropométricos, idade, sexo e etnia, doenças associadas e uso de medicações, além de dados relacionados ao mecanismo de trauma. Como esperado, a maioria dos traumas apresentou mecanismo de baixa energia. Resultados: Houve predominância de 3:1 do sexo feminino, com idade entre 60 e 104 e média de 78,5 anos, havendo um risco maior para pacientes acima dos 80 anos. O índice de massa corpórea (IMC) foi de 16,53 a 39,80, com média de 24,16 kg/m2. Quanto ao mecanismo do trauma, 89,4% dos casos foram de queda da própria altura. Conclusão: Fraturas do fêmur proximal em idosos ocorrem mais em mulheres, com idade média de 78,5 anos, IMC na faixa normal e queda ao nível do solo como principal mecanismo de trauma. A lesão mais prevalente foi a fratura transtrocanteriana, com média de 70,5%, e o tratamento mais realizado foi a fixação interna com haste cefalomedular (66,1%). Nível de Evidência VI, Estudo Epidemiológico Descritivo.

ABSTRACT Objective: To evaluate the age and anthropometry profile of patients with a diagnosis of fracture of the proximal femur in older adults admitted to a philanthropic hospital in São Paulo. Methods: Retrospective observational cross-sectional study. All patients older than 59 years with femoral fractures diagnosed and hospitalized between January, 2019 and April, 2020 were included. The analysis of the 85 medical records resulted in the data collected in the present study. Anthropometry, age, sex, ethnicity, presence of comorbidities and mechanism of trauma of these patients were considered in this study. Most traumas, as expect, presented low energy mechanisms. Results: Prevalence of 3:1 in females, aged between 60-104 and mean of 78.5 years, with an increased risk in patients over 80 years. The body mass index (BMI) between 16.53 and 39.80 with an average of 24.16 kg/m2. Being 89.4% cases of fall from own height. Conclusion: Proximal femur fractures in older adults occur more often in women, with a mean age of 78.5 years, normal BMI range, whose main trauma mechanism is fall to ground level. The most prevalent injury is transtrochanteric fracture, with a mean of 70.5% and the most performed treatment is internal fixation with cephalomedullary nail, with a mean of 66.1%.

Resumo O estudo avaliou a viabilidade da adequação de cardápios em relação às exigências nutricionais estabelecidas pelo Programa Nacional de Alimentação Escolar (PNAE) e a relação entre o custo do cardápio. Cada cardápio semanal contou de uma combinação de alimentos dentro de cada grupo. Para cada combinação de alimentos foi elaborado um modelo de otimização de dados para obter as quantidades de cada alimento de forma a atender às exigências do PNAE ao menor custo possível (cardápios com 20% e 30% da ingestão dietética de referência para energia, macronutrientes, cálcio, ferro, magnésio, zinco, vitaminas A e C, além de restrições para sódio, gorduras saturada e trans, e açúcar de adição). Não foi obtida nenhuma solução que acomodasse todas as exigências do PNAE. Os componentes limitantes foram cálcio, sódio e carboidratos; para os demais os cardápios foram adequados. O custo foi diretamente correlacionado com a frequência de carne e frutas, e inversamente com os conteúdos de sódio e carboidratos, e com as frequências de arroz e feijão. A probabilidade de adequação de carboidratos foi próxima de zero quando a frequência de carne foi acima de 1 vez por semana. Concluindo, é pouco provável a obtenção de cardápios que atendam à todas as exigências do PNAE.

Abstract We evaluated the feasibility of the menu adequacy regarding the nutritional constraints established by the National School Feeding Program (PNAE) and its relation to the cost. Each menu accounted for a given food combination within each food group. A diet optimization model comprising each set of foods was designed to obtain food quantities in order to meet the exigences of the PNAE at the lowest cost (menus with 20% and 30% of dietary reference intake for energy, macronutrients, calcium, iron, magnesium, zinc, vitamins A and C, also restrictions for sodium, saturated and trans fats, and added sugar). There was no feasible solution that accommodated all nutrient targets. Limiting components were calcium, sodium, and carbohydrates; but the menus were adequate for the other nutrients. There was a positive correlation between the menu cost and the frequency of meat and fruits, and a negative correlation with the contents of sodium and carbohydrates, and with the frequencies of rice and beans. The probability of obtaining carbohydrate adequacy was close to zero when the meat frequency was higher than one serving per week. In conclusion, it is unlikely to obtain menus that meet all the requirements of the PNAE.

Resumo A obra O livro didático de Ciências no Brasil, organizada por Hilário Fracalanza e Jorge Megid Neto, foi publicada em 2006. Mais de 10 anos após sua publicação, algumas de suas proposições precisam ser reanalisadas, dadas as alterações sofridas pelo Programa Nacional do Livro Didático (PNLD), que geraram impacto nos próprios livros. Este trabalho compara enunciados dos capítulos do livro com guias do livro didático produzidos pelo Ministério da Educação, pesquisas sobre o livro didático de ciências e manuais escolares produzidos durante a vigência do PNLD. Em que pesem as desatualizações da obra de Fracalanza e Megid Neto, muitos de seus apontamentos permanecem válidos, embora necessitem ser relativizados à luz das complexas relações enunciativas em que se situam os manuais escolares atualmente.

Abstract More than ten years after the publication of the book “O livro didático de Ciências no Brasil” [The Science textbook in Brazil], edited by Hilário Fracalanza and Jorge Megid Neto, in 2006, some of its propositions require a reanalysis due to changes in the National Textbook Program (PNLD). This paper compares excerpts from the book’s chapters with Didactic Book Guides produced by the Ministry of Education, researches on Science textbooks, and textbooks produced during the term of the PNLD. Despite the outdated assertions in the book of Fracalanza and Megid Neto, many of their statements remain valid until the present days, requiring but a relativization in light of the complex enunciative relations in which school textbooks are currently situated.

ABSTRACT Purpose: Prostate cancer screening in the elderly is controversial. The Brazilian government and the National Cancer Institute (INCA) do not recommend systematic screening. Our purpose was to assess prevalence and aggressiveness of prostate cancer in men aged 70 years and above, on the first Latin American database to date. Materials and Methods: Cross-sectional study (n=17,571) from 231 municipalities, visited by Mobile Cancer Prevention Units of a prostate-specific antigen (PSA) based opportunistic screening program, between 2004 and 2007. The criteria for biopsy were: PSA>4.0ng/ml, or PSA 2.5-4.0ng/ml with free/total PSA ratio ≤15%, or suspicious digital rectal examination findings. The screened men were stratified in two age groups (45-69 years, and ≥70 years). These groups were compared regarding prostate cancer prevalence and aggressiveness criteria (PSA, Gleason score from biopsy and TNM staging). Results: The prevalence of prostate cancer found was 3.7%. When compared to men aged 45-69 years, individuals aged 70 years and above presented cancer prevalence about three times higher (prevalence ratio 2.9, p<0.01), and greater likelihood to present PSA level above 10.0ng/ml at diagnosis (odds ratio 2.63, p<0.01). The group of elderly men also presented prevalence of histologically aggressive disease (Gleason 8-10) 3.6 times higher (p<0.01), and 5-fold greater prevalence of metastases (PR 4.95, p<0.05). Conclusions: Prostate cancer screening in men aged over 70 may be relevant in Brazil, considering the absence of systematic screening, higher prevalence and higher probability of high-risk disease found in this age range of the population studied.

Considering the importance of non-school educational spaces to diffusing scientific knowledge, as well as arguments for the inclusion of such spaces into initial teacher education, this study presents four strategies to make them practice field institutions in chemistry teacher licensure programs. Assuming that the modalities of the educational phenomenon can be divided into unsystematic and systematized - whether they be school or non-school forms -, the strategies were named as follows: a) Learning (from) the concept of systematicity; b) The school learns from the museum (or the museum learns from the school); c) The museum in the school; and d) Systematizing non-systematic school education. After describing the strategies, we analyzed reports of chemistry teachers in training. These reports included reflections on the social importance of school and chemical knowledge, and they overcame the technical and practical rationalities by incorporating principles of critical rationality.

Resumo O karate é uma luta originária de Okinawa, ilha ao sul do Japão. Historicamente, atravessou três períodos: a partir do século XVII, como bujutsu, técnica clandestina de luta; depois, como budo, quando foi convertido em luta tradicional japonesa, em fins do século XIX, propugnando valores educacionais e identitários; e finalmente, como esporte de luta, quando foi associado a performance motora e competitividade, no século XX. Ao considerar o papel do karate como veiculador de valores de um Japão idealizado – japonesidade –, este trabalho analisa representações cinematográficas dessa luta. A análise focou nos aspectos educativos retratados nos filmes, a série estadunidense The karate kid e o japonês Kuro obi, sendo conduzida conforme três categorias: a relação entre teoria e prática; ruídos e conflitos entre professor e aluno; e formação do aluno como futuro professor. Os resultados revelam que as obras criticam a esportivização do karate, enfatizando a representação de aspectos educacionais associados aos períodos do bujutsu e, principalmente, do budo. Também, colaboram para reafirmar e atualizar a japonesidade, ao tratar os princípios do budo e sua transmissão educacional de forma idealizada, sem aludir a seu caráter moderno. Ainda, os filmes apresentam divergências em relação à proposta contemporânea de uma pedagogia das lutas, fundamentada na ciência da motricidade humana. Por outro lado, as produções cinematográficas contribuem para a área educacional na medida em que possibilitam discussões a respeito dos processos formativos e seus percalços, retratados de forma original, recorrendo aos conceitos de yin/yang relacionados aos princípios zen-budistas do budo.

Abstract Karate is a fighting style that originated in Okinawa, an island in the south of Japan. Historically, it spans over three periods: from the seventeenth century, as bujutsu, a clandestine fighting technique; later, as budo, when it was turned into a traditional Japanese combat form in the late nineteenth century, promoting educational and identity values; and finally as a fighting sport, when it was associated with motor performance and competitiveness in the twentieth century. In considering the role of karate as a carrier of values of an idealized Japan – Japaneseness –, the present study analyzes representations of this fighting style in filming. The analysis focused on the educational aspects portrayed in the American film The Karate Kid (and its two sequels) and in the Japanese film Kuro Obi, being conducted according to three categories: the relationship between theory and practice; noises and conflicts between teacher and student; and student training as a future teacher. Results show that these cinematographic works criticize the sportivization of karate while emphasizing the representation of educational aspects associated with the periods of bujutsu and, specially, of budo. They also collaborate to reaffirm and actualize Japaneseness by treating the principles of budo and its educational transmission in an idealized way, without alluding to its modern form. Moreover, the films diverge from the contemporary proposal of a pedagogy of martial arts based on the science of human motricity. On the other hand, these cinematographic productions contribute to the educational area in that they allow discussions about educational processes and their mishaps, which are portrayed in an original way, using the concepts of yin/yang related to the Zen Buddhist principles of budo.

Abstract Introduction: the prevalence of hospital malnutrition is high and involves an increase in health care costs. Home hospitalization (HH) allows better clinically stable patient control after an acute illness by a highly specialized health care team. Objective: to know the nutritional condition of home hospitalization patients using a computer application that allows the implementation of early nutritional measures at home and improves post-hospital control of these patients. Material and methods: prospective multicenter study of the nutritional condition of patients in four different home hospitalization centers during a period of two consecutive months in 2016. Variables were collected: home hospitalization, age, gender, reason for admission, associated morbidity, origin, diagnosis, social assessment, previous nutritional support, height, weight, weight loss, time of weight loss, total proteins, albumin, lymphocytes, cholesterol, body mass index (BMI), nutritional condition, type and degree of malnutrition. Nutritional condition was assessed using the application HEN-Persan and results were statistically analyzed using the SPSS 21.0 software. Results: no significant differences were found between the four centers. In home hospitalization patients, 36% presented a normal nutritional screening and 87% presented some degree of malnutrition, while combined malnutrition prevailed (63%). Depending on the nutritional degree, 36% of patients had mild malnutrition, 27% presented moderate malnutrition and 35% had severe malnutrition. Conclusions: a computer application allows for an immediate, secure and reliable nutritional assessment in home hospitalization that helps introduce early nutritional measures and improve post-hospital control of patients.

Resumen Introducción: la malnutrición hospitalaria tiene una elevada prevalencia y comporta un incremento del coste sanitario. La hospitalización a domicilio (HaD) permite el control en el domicilio de un episodio hospitalario agudo estable clínicamente por un equipo sanitario especializado. Objetivo: conocer el estado nutricional de los pacientes que ingresen en HaD con una misma aplicación informática (app) para poder instaurar medidas nutricionales precoces en el domicilio y mejorar la evolución posthospitalaria de los pacientes. Material y metodología: estudio multicéntrico prospectivo y descriptivo del estado nutricional en cuatro unidades de HaD, durante un periodo de dos meses consecutivos durante el año 2016. Se recogieron las variables: unidad de HaD, edad, sexo, motivo de ingreso, patología asociada, procedencia, diagnóstico, valoración social, soporte nutricional previo, talla, peso, pérdida de peso, tiempo de la pérdida de peso, proteínas totales, albúmina, linfocitos, colesterol, índice de masa corporal (IMC), estado nutricional según el IMC, riesgo nutricional, tipo y grado de desnutrición. Se realizó la valoración nutricional con la app HEN-Persan y se analizaron los resultados estadísticamente con el programa informático SPSS 21.0. Resultados: no existen diferencias significativas entre las cuatro unidades. Globalmente, el 36% de pacientes ingresados en HaD presentaban un estado nutricional normal. El 87% presentaba algún tipo de malnutrición, predominando la desnutrición de tipo mixta (63%). Según el grado, fue leve (36%), moderada (27%) y grave (35%). Conclusiones: la utilización de una app permite tener una valoración nutricional inmediata, de manera fácil, segura y fiable en HaD, para poder introducir medidas nutricionales precoces y mejorar la evolución posthospitalaria de los pacientes.

Resumo Objetivo: O artigo apresenta uma avaliação econômica de opioides atualmente utilizados no controle de dor pós-operatória relacionada ao tratamento cirúrgico do câncer (fentanil e sufentanil) no contexto do Sistema Único de Saúde. Método: A avaliação baseou-se na perspectiva do governo, de forma a colaborar na promoção da efetividade das políticas públicas de saúde e melhorar a alocação de recursos públicos em saúde. Uma análise custo-efetividade foi realizada a partir de dados coletados no Sistema Único de Saúde e de informações provenientes de revisão da literatura para construção de uma árvore de decisão contendo alternativas para controle de dor pós-operatória relacionada ao tratamento cirúrgico do câncer entre pacientes adultos. Os desfechos considerados foram: efetividade da analgesia pós-operatória e ocorrência de náusea e vômito no período de 48 horas após cirurgia e em ciclos adicionais de 24 horas de seguimento do paciente. Uma análise de sensibilidade univariada foi conduzida para verificar a robustez do modelo estimado. Resultados: Na revisão de literatura, um número limitado de estudos efetuou comparação direta entre fentanil e sufentanil no controle de dor pós-operatória. A adoção de sufentanil (custo = U$ 25,72 / desfecho = 1,6 pontos VAS) foi dominante em relação ao uso do fentanil (custo = U$ 32,58 / desfecho = 2,6 pontos VAS). O modelo estimado demonstrou robustez em relação a mudanças nos parâmetros analisados. Conclusão: O sufentanil apresentou razão custo-efetividade superior em relação ao fentanil no controle de dor pós-operatória em cirurgias relacionadas ao tratamento de câncer entre pacientes adultos no Sistema Único de Saúde.

Summary Objective: The authors performed an economic assessment of opioids currently being used for control of postoperative pain relating to the surgical treatment of cancer (fentanyl and sufentanil) within the Brazilian Unified Health System (SUS, in the Portuguese acronym). Method: The assessment was based on the perspective of the government, in order to collaborate with the promotion of effectiveness in public policies of health, and to optimize the allocation of public resources into health. A cost-effectiveness analysis was performed using data collected from the Brazilian Unified Health System and information from literature review, in order to build a decision tree on the alternatives for control of postoperative pain related to cancer treatment among adult patients. The outcomes considered were: effectiveness of postoperative analgesia and occurrence of nausea and vomit in the 48 hour period after surgery, and additional 24-hour cycles in patient follow-up. A univariate sensitivity analysis was conducted in order to verify robustness of the model estimated. Results: Literature review showed a limited number of studies directly comparing fentanyl and sufentanil for control of postoperative pain. The adoption of sufentanil (cost = U$ 25.72 / outcome = 1.6 VAS points) was dominant in relation to the use of fentanyl (cost = U$ 32.58 / outcome = 2.6 VAS points). The estimated model showed robustness in relation to changes in the parameters analyzed. Conclusion: Sufentanil presented higher cost-effectiveness ratio in relation to fentanyl for control of postoperative pain in surgeries related to cancer treatment among adult patients in the Brazilian Unified Health System.

Resumo: O objetivo deste trabalho foi avaliar o crescimento dos enxertos e a caracterização anatômica de cultivares de pereira e marmeleiro enxertadas nos porta-enxertos Pyrus calleryana e Chaenomeles sinensis. Foram feitas avaliações quanto às percentagens dos enxertos brotados aos 60 dias e quanto ao comprimento e o diâmetro da brotação dos enxertos aos 120 dias. Cortaram-se porções caulinares da região da enxertia, em seções transversais e longitudinais, e o xilema secundário foi separado para comparação dos tecidos. As pereiras apresentaram bom desenvolvimento sobre o porta-enxerto P.calleryana, e os cortes anatômicos apresentaram tecidos vasculares conectados, o que não ocorreu quando as pereiras foram enxertadas em C.sinensis, em que os enxertos brotaram mas não se desenvolveram, e os tecidos vasculares não se conectaram. Os marmeleiros apresentaram bom desenvolvimento em ambos os porta-enxertos, em razão da boa conexão dos tecidos vasculares. A conexão dos tecidos vasculares é fundamental para o sucesso da enxertia. As espécies utilizadas não diferiram significativamente quanto a seus tecidos do xilema secundário. A incompatibilidade encontrada entre as pereiras e o porta-enxerto C. sinensis não é anatômica.

Abstract: The objective of this work was to evaluate the graft growth and the anatomical characterization of pear (Pyrus communis x P. pyrifolia) and quince (Cydonia oblonga) cultivars grafted on Pyrus calleryana and Chaenomeles sinensis rootstocks. Sprouted graft percentages at 60 days and the length and diameter of the graft sproutings at 120 days were evaluated. Stem cuttings from the grafting region were performed in transversal and longitudinal sections, and the secondary xylem was separated for tissue comparison. The pear trees showed good development on P.calleryana rootstock, and the anatomical sections showed that the vascular tissues were connected, which did not occur when the trees were grafted on C.sinensis, in which the grafts sprouted, but did not develop, and the vascular tissues did not connect. The quince trees showed good development on both rootstocks due to the good connection of the vascular tissues. The connection of vascular tissues is essential for the success of grafting. The evaluated species did not differ significantly as to their secondary xylem tissues. The incompatibility found between the pear trees and the C.sinensis rootstocks is not anatomical.

Abstract: Objective: To analyze efficiency indicators of human resources working at Mexico's Ministry of Health. Materials and methods: Three dimensions of efficiency were explored: a) labor wastage, b) distribution of human resources (HR) across levels of care, and c) productivity. Results: Health workers present significant levels of unemployment and underemployment; distribution does not meet international recommendations, and heterogeneous levels of productivity were found among states. Conclusions: Health and educational authorities should develop and implement a HR plan that takes into consideration the needs and demands of the covered population, and includes a clearly defined set of measures to regulate the future production of HR as well as their distribution among and within state health systems, and that allocates incentives to improve performance.

Resumo Este trabalho procura realizar um diálogo entre o pensamento do filósofo e educador brasileiro Dermeval Saviani e os estudos sobre a educação em museus e centros de ciências. Primeiramente, investigamos o desenvolvimento histórico dessas instituições para, em seguida, analisarmos, nas obras de Saviani, menções às formas não escolares de educação. A partir dos textos do educador brasileiro, e considerando os diferentes sentidos que a literatura confere às expressões educação informal e educação não formal, propõe-se que as modalidades de educação sejam situadas entre as categorias sistematizada / assistemática e escolar / não escolar. Assim, compreendendo-se a educação museal como uma modalidade de educação não escolar que vem se sistematizando, e a especificidade dos museus frente aos conceitos de conhecimento e cultura, são comentadas algumas possibilidades para que tais instituições colaborem para a democratização do saber, complementando e valorizando a educação científica escolar. Em acordo com a concepção crítica de Saviani, considera-se que os museus e centros de ciências, no estabelecimento de ações educativas, possam contribuir para a elevação da qualidade do ensino de ciências, estabelecendo uma relação comunicativa entre os saberes museais e os saberes escolares. Dessa maneira, não se dissolvem nem a especificidade da instituição museal enquanto guardiã do patrimônio da humanidade, nem a especificidade da escola enquanto transmissora da cultura para as novas gerações.

Abstract This work aims to conduct a dialogue between the thoughts of Brazilian philosopher and educator Dermeval Saviani and studies about education in science museums and centers. Firstly, we investigate the historical development of these institutions, and then analyze mentions to non-school forms of education in Saviani’s works. Based on the writings of this Brazilian educator, and considering the different meanings that the literature assigns to informal education and non-formal education, we propose to situate education modalities between the systematized/unsystematic and school/non-school categories. Thus, by understanding museum education as a modality of non-school education that is becoming systematized, and the specificity of museums concerning the concepts of knowledge and culture, we comment on some possibilities for these institutions to collaborate in making knowledge democratic, thus complementing and valuing school science education. In line with Saviani’s critical position, we consider that, as science museums and centers establish education actions, they could contribute to improve the quality of science teaching by establishing a communicative relationship between museum knowledge and school knowledge. Thus, the specificity of the museum institution as the guardian of human heritage is not dissolved, nor is the specificity of school as the transmitter of culture to new generations.
