Experimental study of the influence of friction at the supports on longitudinal shear resistance of composite slabs

Abstract The aim of this work is to evaluate the behavior and strength of composite slabs considering the influence of the friction at the sheeting-concrete interface in the region of the support. Results from tests conducted in the Structural Engineering Department of Federal University of Minas Gerais (UFMG) were used. A Steel Deck 60 system was considered, which consists of a trapezoidal profile with “V” shaped embossments. Deflections, end slips and strains of the steel decks were measured, allowing for the analysis of the behavior of the composite slab system and for the determination of its failure mode. The influence of friction of the region of support in the longitudinal shear resistance was evaluated through the partial shear connection method, which also allowed for establishing criteria and determination of analytical expressions for calculating the ultimate load. Comparative analyses reveal that the influence of the friction of the region of support in the shear-bond resistance is more significant in composite slabs with short shear spans. Design expressions which incorporate friction will also be presented. Their application have demonstrated the efficiency of the method for evaluating the longitudinal shear resistance.

Effectiveness of Medical-Care Equipment Management: Case Study in a Public Hospital in Belo Horizonte / Minas Gerais

This study aimed to identify and analyze the factors that contribute to the effectiveness of the management of medical-care equipment at the Hospital of Federal University of Minas Gerais (HC-UFMG) in Belo Horizonte, Minas Gerais. To achieve this goal, a case study was performed along with a field research at HC-UFMG, through interviews using a semi-structured questionnaire to professionals who handle and operate medical-care equipment; professionals who provide maintenance on equipment, and professionals who manage the operation and maintenance of equipment. As a strategy for discussion of the results, the Collective Subject Discourse (CSD) was used supported by the analysis of the Central Idea (CI) of each question or question groups. According to the CSD results, it was possible to identify factors that contribute to the effectiveness of the management of medical-care equipment, such as: professional qualification; practical knowledge; work professionalization; supervision focused on evaluation, development, results and continuous improvement; professional updating and technical support; individual accountability; adequate infrastructure; and implementation of equipment management planning. These factors indicate, to the institutions, opportunities of culture change and organizational growth.

Pedagogia e máscaras: entrevista com dois mestres canadenses

É no contexto do pós-doutoramento intitulado "Brincantes mascarados da cultura popular: possibilidades para a formação do artista cênico na contemporaneidade" que insiro as duas entrevistas a seguir. A primeira aconteceu no início de 2016 na UFMG em Belo Horizonte, quando Steve Jarand trouxe um workshop de máscaras expressivas durante três dias e organizado por Mariana Muniz, que foi também a tradutora no momento da entrevista. A segunda aconteceu com Sue Morrison no início de 2017 em Toronto – Canadá, quando finalizei um workshop de Clown Through Mask. Para esse momento foram fundamentais as participações de Isaac Luy como tradutor e Mayara Gabaldi no registro em áudio e transcrição do diálogo na língua inglesa.

Retrospective analysis of 103 diaphragmatic injuries in patients operated in a trauma center.

to analyze the factors associated with death in patients with diaphragmatic injury treated at a trauma reference hospital. we conducted a retrospective study of patients with diaphragm injury attended at the Risoleta Tolentino Neves Hospital of the Federal University of Minas Gerais, between January 2010 and December 2014. We used The Collector® database of trauma records (MD, USA). We gathered data on demographics, location of the diaphragmatic lesion, site and number of associated lesions, type of therapeutic approach, complications and Injury Severity Score (ISS). The variable of interest was the occurrence of death. we identified 103 patients and mortality was 16.5%. Penetrating lesions occurred in 98% of patients. Univariate analysis showed a mortality higher in patients whose treatment was non-operative, without closing of the defect (p=0.023), and lower in patients submitted to diaphragmatic suturing (p<0.001). The increase in the number of lesions was associated with an increase in mortality (p=0.048). In multivariate analysis, ISS>24 (OR=4.0, p=0.029) and diaphragmatic suturing (OR=0.76, p<0.001) were associated with mortality. The findings indicate that the traumatic rupture of the diaphragm rarely presents as an isolated lesion, being frequently associated with injuries of other organs, especially the liver and hollow viscera. Mortality was higher among those with ISS>24.

Event review: Seminário Nacional de Tecnologia Lítica, Goiânia, Brazil

Between 5 and 9 October of 2016 the Seminário Nacional de Tecnologia Lítica (National Seminar of Lithic Technology) took place on the campus of the Pontifical Catholic University of Goiás, Brazil. The seminar aimed to create a space of exchange and learning among students, researchers and professors which currently work with prehistoric lithic technology, developing studies in different regions of Brazil, in addition to the special participation of a researcher from Peru. The event was conceived and developed through the efforts of three Brazilian institutions: the Pontifical Catholic University of Goiás (Dr. Sibeli A. Viana and Marcos Paulo Ramos), the University of Pelotas, Rio Grande do Sul (Dr. Maria Gluchy), and the Federal University of Minas Gerais (Dr. Jacqueline Rodet), in addition to a partnership with Paris West University Nanterre La Défense (Dr. Eric Boeda). Activities of practical analysis on lithic material and knapping were developed with the aim of better understanding the methods and techniques involved in the production of archaeological tools. As the event sought to develop practical activities, with dynamic ones, it was accompanied by monitored knapping sessions. It was necessary to restrict the participation to a small number of people (20). Still, there was participation by students from undergraduate, master's, and doctoral programs. As well, places were reserved for archaeologists working with rescue projects involving lithic period sites.

Avaliação da qualidade microbiológica e físico-química da água consumida em escolas municipais de Divinópolis/MG

Tendo em vista a ausência de informações acerca da qualidade da água consumida em escolas municipais de Divinópolis - MG, o presente trabalho teve como objetivo levantar dados, de natureza microbiológica e físico-química, de amostras de água coletadas em unidades de ensino da cidade a luz da Portaria 2.914/2011 do Ministério da Saúde (MS). Com a autorização da Secretaria Municipal de Educação (SEMED) as coletas foram realizadas nos meses de junho, julho e agosto de 2016, e os experimentos conduzidos no Laboratório de Microbiologia da Universidade do Estado de Minas Gerais (UEMG) - Unidade Divinópolis MG e no Laboratório de Química de Proteínas da Universidade Federal de São João (UFSJ) - Campus Centro-Oeste (CCO). Foram assepticamente coletadas amostras em variados pontos de cada unidade escolar: caixa d’água, bebedouro e torneira da cozinha, seguindo manual prático de análise de água da FUNASA - 2013. Foram avaliados 8 parâmetros por ponto divididos em 3 microbiológicos e 5 físico-químicos. Para avaliação da presença de coliformes totais e termotolerantes foi adotada a metodologia do substrato cromogênico e empregada a técnica spread-plate para a contagem padrão de bactérias heterotróficas totais. Em relação aos parâmetros físico-químicos foram analisados cloro residual livre, pH, temperatura, cor aparente e turbidez, conforme protocolos padronizados. Ao longo do desenvolvimento dos trabalhos foram percorridos aproximadamente 420 km e avaliadas amostras de água de 15 escolas, sendo 9 da zona urbana e 6 da zona rural, selecionadas de tal forma a garantir distribuição espacial suficiente para cobrir boa parte da extensão territorial do município. Das 15 escolas analisadas somente 3 atenderam a todos os padrões de potabilidade, representando apenas 20% do total. As demais escolas apresentaram um ou mais parâmetros em desconformidade legal, totalizando 80% das unidades avaliadas.

Quantification and Determination of Starch in Diets Using Different Methodologies: Infrared Spectroscopy with Fourier Transformer, Laser Diffraction and Enzymatic Analysis

A digestibility experiment was conducted in the Animal Nutrition Laboratory of the Veterinary School of the Federal University of Minas Gerais (UFMG), Protocol ethics committee for work with animal experimentation CETEA/ UFMG 212/2010, in order to validate the instrumental techniques Laser Diffraction (Partica) and Infrared Spectroscopy with Fourier Transformer (FTIR) method, as replacement methods of the reference (Enzymatic Analysis) Technique, of starch quantification in diets of growing pigs. The experiment lasted 12 days (7 days of adaptation to the cage and diet and 5 days of total collection). Fifteen barrows with average weight of ±25 kg and 65 days old were used for this study. A completely randomized experimental design was adopted, with split plots and subplots. The plots were the diets (1—Reference, 2—Reference + inclusion of 30% micronized soybean and 3—Reference +30% substitution of plasma) and the subplots were the techniques (Partica, FTIR and Enzymatic Technique, with five repetitions (animals) per diet). The results obtained with the Partica and FTIR techniques were compared to the reference method. There was no statistical difference (p > 5%) between these techniques evaluated in comparison to the reference method to quantify starch. However, it was observed that the FTIR technique was different from the reference method for (p > 5%) overestimating the means of evaluated samples.

Health Information Exchange for Continuity of Maternal and Neonatal Care Supporting: A Proof-of-Concept Based on ISO Standard.

Background Around the world, people receive care at various institutions; therefore, clinical information is recorded either on paper or distributed on different information systems with reduced capabilities for sharing data. One approach to handling the complex nature of the health information systems and making it interoperable is the two-level modeling, and the ISO 13606 standard is an option to support this model. A regionally governed EHR program in Brazil proposed to use the ISO 13606 standard and archetypes. This program includes an EHR repository for consolidating the longitudinal electronic record of patients' health. Objective This article aims to present the results and lessons learned from a proof-of-concept (POC) for integrating the Maternal and Neonatal Healthcare Information System (SISMater) developed by the Federal University of Minas Gerais (UFMG) with the EHR system developed by the Department of Healthcare for the State of Minas Gerais (SES/MG). Methods The design of the architecture and software development were driven by the content to be exchanged between the SISMater system and the EHR system and the usage of XML transformation to translate an ISO 13606 EHR extract and vice versa. This POC did not include tests related to revision objects according to ISO 13606 reference model. Results The software architecture and software components required for this POC were proposed and tested. The EHR system validated the syntax and semantic and persisted the extract in the EHR repository. Complete results can be accessed at https://github.com/pocppsus/repository. Conclusion The approach for using XML transformations could make easier the process for ISO 13606 noncompliant EMR systems to exchange EHR data with the SES/MG EHR system.

The Brazilian Twin Registry.

The Brazilian Twin Registry (BTR) was established in 2013 and has impelled twin research in South America. The main aim of the initiative was to create a resource that would be accessible to the Brazilian scientific community as well as international researchers interested in the investigation of the contribution of genetic and environmental factors in the development of common diseases, phenotypes, and human behavior traits. The BTR is a joint effort between academic and governmental institutions from Brazil and Australia. The collaboration includes the Federal University of Minas Gerais (UFMG) in Brazil, the University of Sydney and University of Melbourne in Australia, the Australian Twin Registry, as well as the research foundations CNPq and CAPES in Brazil. The BTR is a member of the International Network of Twin Registries. Recruitment strategies used to register twins have been through participation in a longitudinal study investigating genetic and environmental factors for low back pain occurrence, and from a variety of sources including media campaigns and social networking. Currently, 291 twins are registered in the BTR, with data on demographics, zygosity, anthropometrics, and health history having been collected from 151 twins using a standardized self-reported questionnaire. Future BTR plans include the registration of thousands of Brazilian twins identified from different sources and collaborate nationally and internationally with other research groups interested on twin studies.

The perception of graduate students in early childhood education regarding the oral habits of preschoolers

Aim: This cross-sectional study aimed to assess the perception of graduate students in early childhood education programs about the oral habits of preschoolers. Methods: All 47 graduate students enrolled in the early childhood education program at the Federal University of Minas Gerais (UFMG), Belo Horizonte, Brazil from 2012 to 2013 participated in the study. Participants were approached during their lecture classes and were asked to respond to a pre-tested self-completion questionnaire. Data analysis involved descriptive statistics. Results: The majority of participants were women (95.7%) between 25 and 46 years of age, with a mean of 32.3 years of age (SD = 4.36). Most believed that all children should be bottle fed (91.5%) and use a pacifier(80.9%). The majority also reported that they would like to receive further information on oral health (91.5%). Conclusion: Graduate students in the early childhood education field can be important allies in promoting oral health. However, they need to acquire further knowledge on the subject during their professional training.Uniterms: Nursing bottles. Child. Faculty. Habits. Pacifiers.

Mathematics teachers’ conceptions and constraints for changing teaching practices in Brazilian higher education: an analysis through activity theory

ABSTRACTIn recent years, changes in the Brazilian economic and social scenario have generated a growing demand for higher education in the country. In response to this new context, the federal government launched in 2007 a programme aiming at expansion of the enrolment to public higher education. In such environment of changes, several proposals have emerged to adapt the Brazilian federal universities to a new reality. Taking this context into account, the focus of our study is on proposals from the Mathematics Department of the Federal University of Minas Gerais. Their aim is to create a new model of teaching practices for the freshman lessons of the Exact Sciences area, which at first were being experimented in special classrooms of students attending their first course on differential and integral calculus. The data were collected from interviews with students and professors from the mathematics department. They were analyzed and systematized using an activity theory approach. We became instigated by a model developed by Engeström in his study on the changes in the Finnish public health system, considering it as a test (testbench) for activity theory in its application to a particular case. Following Engeström's footsteps when developing his research, we arrived at our own model showing the internal tensions in the activity of reformulation of the courses offered by the Department of Mathematics and in the conceptions of teachers that promote – and constraint – the proposals for change.

Entre o cristal e a chama: a natureza e o uso do conhecimento científico e dos saberes tradicionais numa disciplina do Curso de Formação Intercultural para Educadores Indígenas da Universidade Federal de Minas Gerais (FIEI/UFMG)

Resumo Neste trabalho discutem-se os significados que envolvem a formação intercultural para educadores indígenas a partir das tensões decorrentes do encontro das diferentes culturas e da pluralidade de saberes em sala de aula. As reflexões têm como panorama as questões em torno da função social da educação escolar indígena em suas articulações com as dinâmicas culturais em suas comunidades, considerando-se tanto a construção da educação básica nas aldeias quanto a formação docente na Universidade Federal de Minas Gerais (UFMG). Para tanto, são analisadas algumas situações vivenciadas em sala de aula, em uma disciplina de formação de educadores indígenas, sob a metáfora do texto visto como chama ou cristal. A experiência permitiu uma melhor compreensão da realidade da educação escolar dos povos indígenas como contato cultural, e não como folclore.

Potencial de mudança nas práticas de saúde: a percepção de trabalhadores de uma Rede de Reabilitação em (trans)formação

RESUMO A saúde da pessoa com deficiência alcançou prioridade na agenda do governo brasileiro, resultando na formulação de políticas específicas para esses usuários no Sistema Único de Saúde (SUS). A criação de uma rede de cuidados à pessoa com deficiência e o uso da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) estão entre as normativas recentemente publicadas. Esta pesquisa qualitativa examinou uma proposta de capacitação articulada entre Universidade Federal de Minas Gerais e Secretaria Municipal de Saúde, concebida para auxiliar a reorientação da Rede de Reabilitação de Belo Horizonte a partir do modelo da CIF. Teve como objetivo conhecer a percepção de profissionais sobre suas experiências nos cenários do SUS à luz dos conhecimentos adquiridos sobre o modelo da CIF, e este como potencial de mudança das práticas cotidianas de trabalho e construção da Rede de Saúde. Utilizou-se análise documental, observação não participante e grupos focais. A análise de conteúdo permitiu identificar dois eixos temáticos: consonância entre trabalho e formação profissional e potência do modelo biopsicossocial para a organização da reabilitação. Os resultados revelaram distanciamento entre formação acadêmica e realidade de trabalho e, ao mesmo tempo, um processo de transformação da forma de conceber constructos importantes para a reorientação da reabilitação, como funcionalidade, contexto e a relação entre eles. O modelo assistencial vigente ainda encontra inconformidades para a coordenação integral do cuidado, mas motivação, conhecimento das políticas públicas e mudanças na formação de profissionais para o SUS podem facilitar a comunicação entre atores e serviços, favorecendo o trabalho em rede.

DIVULGAÇÃO SOBRE A UNIVERSIDADE FEDERAL DE MINAS GERAIS PARA ALUNOS DE ESCOLAS PÚBLICAS DA REGIÃO METROPOLITANA DE BELO HORIZONTE

Entrance to a Brazilian public university still has been considered an almost unattainable goal for many high school students. Besides, it is extremely surprising that many of these students do not know the actions to be taken to gain access to higher education. Within the context of a lack of information, the project Grupo de Estudantes que Multiplicam e Transformam Ideias (GEMTI) developed educational activities that enabled students from Federal University of Minas Gerais (UFMG) and students from public schools of metropolitan area of Belo Horizonte to exchange knowledge among them. It was conducted by reading scientific articles, meetings with the group, audiovisual technology and questionnaires.Through the interventions it became clear that there is a gap in the education system. Thus, the GEMTI team believes that the outreach actions contributed positively to give them opportunity to reflect and to obtain knowledge as well as contributing to improve their professional future and the students as well.

The university and metropolitan planning: an innovative experience

Abstract: The Federal University of Minas Gerais (UFMG) has been carrying out an experience of metropolitan planning in Belo Horizonte, Brazil, since 2009, involving a significant number of faculty and students. In this paper, we highlight some of the innovative aspects of this planning process. We stress the specificities of a planning experience conducted under the auspices of the University in an attempt to move beyond both its disciplinary and academic boundaries. Therefore, we emphasize the participatory dimension in which the University team is engaged along with civil society. We also describe proposals that put the environmental concern at the forefront of metropolitan restructuring and the efforts to materialize them through a Green and Blue Weft (Trama Verde e Azul - TVA). Finally, we discuss our understanding of planning as a political process beyond the institutionalized public policy practice in an attempt to give voice and visibility to different ways of seeing and making the metropolitan region.

O portfólio: um estudo das representações sociais dos licenciandos em ciências biológicas

Há muito se tem falado sobre as vantagens do Portfólio como um instrumento de avaliação da aprendizagem, mas sabemos que as indagações acerca de como ocorre a sua construção ainda são questões pouco discutidas. Esta pesquisa de cunho quanti-qualitativo, pretende identificar e analisar as Representações Sociais dos alunos do curso de Licenciatura em Ciências Biológicas, na modalidade a distância, de uma Universidade mineira sobre a realização do Portfólio como instrumento de avaliação formativa. Considerando o objeto de estudo desta pesquisa - a construção do Portfólio como instrumento de avaliação formativa -, cabe aqui evidenciar o Portfólio como um procedimento de avaliação na Educação a Distância, de organização e reconstrução das aprendizagens, que permite aos alunos participar da formulação e da sistematização dos objetivos propostos, assim como avaliar seu progresso, suas potencialidades e fragilidades. O estudo foi realizado por meio de pesquisa bibliográfica e de campo. A pesquisa bibliográfica fundamenta-se em autores da Teoria das Representações Sociais e do Núcleo Central, do Portfólio, da Educação a Distância e da Avaliação formativa. Participaram da pesquisa de campo 150 alunos do curso de Licenciatura em Ciências Biológicas, na modalidade EAD, dos polos de Barbacena, Belo Horizonte, Governador Valadares, Guanhães, Janaúba, Montes Claros. Teófilo Otoni e Uberaba, que estão cursando as etapas finais da sua formação acadêmica. A coleta dos dados foi realizada a partir de um questionário. Ele apresenta dois objetivos: o primeiro é identificar o perfil dos sujeitos, uma vez que os dados caracterizadores do perfil apresentam relação com as Representações Sociais; o segundo, identificar se os licenciandos do curso de Ciências Biológicas reconhecem o Portfólio como um instrumento de avaliação formativa. Quanto aos caminhos metodológicos seguidos, esta investigação, toma como referencial teórico-metodológico as Representações Sociais, descritas como expressões do conhecimento reconstruído pelo sujeito a respeito de sua realidade cotidiana. Essas representações são resultantes da interação social e influenciam o nosso modo de pensar, sentir e agir diante das experiências da vida prática. Por isso, nesta pesquisa destacam-se as atitudes, as percepções, os juízos de valor e as crenças dos alunos, no que se refere à construção do Portfólio na modalidade a distância. Concluindo, podemos afirmar que a construção do Portfólio, no curso de Ciências Biológicas da Universidade mineira, apresenta elementos que o caracterizam como instrumento de avaliação formativa. Porém, sugerimos à instituição, estudos mais sistematizados sobre a construção do Portfólio, visando a expandir o repertório de variáveis e conhecimentos sobre esse sistema de avaliação, já que, ao mesmo tempo, esse processo cria representações que irão dificultar sua prática pelos próprios alunos. Entendemos que empreender uma pesquisa, procurando identificar quais são as Representações Sociais dos licenciandos em Ciências Biológicas, na modalidade a distância sobre a construção do Portfólio como instrumento de avaliação, pode traduzir-se em contribuições relevantes para cursos de formação de professores e instituições que utilizam ou têm intenção de utilizar o Portfólio como instrumento de avaliação formativa.
