In women affected by leprosy, work and daily activities are directly affected; this deepens the social difficulties and requires attention of health professionals.
Objectives: to analyze the understanding of homeless people living in a city in the countryside of São Paulo about what health is and about their experiences in health services. Methods: a qualitative exploratory study developed through interviews with homeless people and a field diary. The data were organized by themes and the findings were compared to a collective health framework. Results: the explored themes were: “Being healthy for the homeless population”, “The search for health services” and “Being a user of health services from the perspective of homeless people”. We present the interviewees’ understanding of health and their experiences in healthcare services. Along this path, we outline aspects that show the network’s weaknesses, permeated by prejudices and discrimination. Final Considerations: this population has conceptions about health and needs that need to be singularly taken into consideration to facilitate access and care.
RESUMONesse trabalho, apresenta-se uma das aplicações da modelagem matemática no sistema cardiovascular, a sua utilização na estimação do volume ventricular esquerdo -um parâmetro fundamental no diagnóstico de doenças cardíacas. Para isso, prepara-se um molde de um ventrículo esquerdo bovino, seu volume real é determinado e, então, comparado com os resultados obtidos por métodos matemáticos médicos e com um novo método proposto, baseado na integral de revolução de uma função polinomial específica. Os resultados preliminares indicam que o método proposto é mais eficiente que os métodos médicos, com diferença de apenas 3,5% do volume real.Palavras-chave: Modelagem Matemática. Novo Método de Cálculo. Volume Ventricular. ABSTRACTIn this work, we presented one of the applications of mathematical modeling to the cardiovascular system, its use in the estimation of the left ventricular volume, which is a basic parameter in the diagnosis of heart disease. To do that, a mold of a bovine left ventricle is prepared, its real volume is determined and then it is compared to the results achieved by medical mathematical methods and with a new proposed method, based on the integral of revolution of a specific polynomial function. Preliminary results indicate that the proposed method is more efficient than medical methods, with a difference of only 3.5% of the actual volume.
O objetivo desse trabalho é obter um modelo matemático para a evolução populacional da cidade de Pirapora/MG, baseando-se apenas nos dados de censos e contagens populacionais do Instituto Brasileiro de Geografia e Estatística (IBGE). Para isso, é utilizada a interpolação por splines cúbicas, pois as técnicas de interpolação linear e polinomial, e também o modelo logístico, não se ajustam bem a essa população. Os dados analisados não são equidistantes, então, utiliza-se como amostra anos separados com passo h de 10 anos. Os valores descartados inicialmente e as estimativas populacionais para esse município, descritos pela Fundação João Pinheiro, serviram para validação do modelo construído, e para a estimativa das diferenças percentuais de previsão, que não ultrapassaram os 2,21%. Ao se considerar que o padrão de evolução populacional de 2000 a 2010 se manterá até 2020, estima-se as populações da cidade de 2011 a 2020, cuja diferença percentual média foi de apenas 0,49%. Conclui-se que o modelo se ajusta muito bem aos dados, e que estimativas populacionais em qualquer ano de 1970 e 2020 são confiáveis. Além disso, o modelo permite a visualização prática de uma aplicação dessa técnica na modelagem populacional, e, portanto, também pode ser utilizada para fins didáticos.Palavras-chave: Splines cúbicas.

Objective: to know the interferences of leprosy in women's lives and how they reinvent themselves in coping with the disease. Method: a descriptive study with a qualitative approach. The theoretical-methodological framework adopts an approximation to the cartographic method and some concepts of schizoanalysis, which were used to analyze the data. The tools used to produce the data were the interview and the logbook. The interviews were conducted from July to November 2019, at the participants' homes. Results: the group consisted of nine women. To display the data, we were inspired by Deleuze's ideas about difference and repetition. The results were organized in three thematic axes that address the lives of these women affected by leprosy, which accompany concerns, anxieties and worries about the effects of the disease. The transformations in the female body, the financial maintenance itself due to the comorbidities caused by leprosy and its difficulties in guaranteeing rights are elements strongly pointed out by women. Conclusion: there is overlap and interference of the female condition in a patriarchal society that still accompanies it. We bet on the strength of becoming-a-woman and the need to consider them in their singularities and in their context for producing care permeated by meetings of the affirmation of the power of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
