Shear Strength of a Synthetic Transparent Soft Clay Using a Miniature Ball Penetrometer Test
Authors: Ads Abdelaziz , Iskander Magued , Bless Stephan
Published: October 2019

This article is concerned with the properties of Laponite colloids, which are being used as a transparent surrogate for soft natural clays. Laponite is a synthetic smectite clay similar to natural hectorite clay that is made of magnesium lithium phyllosilicate (MLPS). The effect of aging on the shear strength of transparent soft clay formed from MLPS and water is presented in this article. A miniature ball penetrometer (MBP) was developed for this study. MBP tests were used to measure the shear strength of samples at three different concentrations of MLPS in water. Sodium pyrophosphate was used to slow down the flocculation of MLPS by altering its rheology, thus improving the transparency of higher MLPS concentration samples. Parameters that were studied included the water quality, aging, penetration rate, penetrometer geometry, and repeatability. The strength of clays made of MLPS was found to increase with MLPS concentration, depth, and penetration rate. Water quality had little effect on strength or transparency. Equations to predict the strength of MLPS based on constituents, age, and stress, as well as the effect of rate of loading, are proposed. The performance of the MBP test was also investigated. It showed excellent repeatability, although the shear strength measured was dependent, to some degree, on the penetrometer’s dimensions as well as the rate of loading.
Reduction of noise and interference by rational selection of electronic components in lumped parameter channels at high speed data processing
Authors: Tynynyka A. N.
Published: October 2019

When designing most electronic systems, the main focus is on the development of the devices themselves, while the problem of meeting the requirements for the interference protection usually take second place, which calls for a need in this particular study. The article is devoted to methods and rules for design of radio electronic devices, which reduce noise and interference. The author provides practical guidance in the issues of choosing components, installing cables and connectors, designing print nodes and interference filtering. The urgency of these tasks is caused by several principal reasons, i.e., the increase of the speed of semiconductor devices and electronic circuits in general, reducing the amplitudes of the working signals of digital devices, increasing effect of interconnects and cascade layouts on the stability and speed of electronic devices and systems, the complex, costly and time consuming process of finding and eliminating the causes of low noise immunity of electronic devices. With the speed growth and the layout density of the elements, ensuring the noise immunity of the electromagnetic interaction between different devices and systems becomes the most important task of designing the radio electronic systems in general. When designing any electronic circuit, additional resistive, inductive and capacitive parasitic parameters are inevitably introduced. This can critically affect the performance of the real-life design by lowering its speed and noise immunity, even leading to complete failure. Design and installation have a particularly strong influence on the operation of high-speed (high-frequency) circuits and devices. In such cases, system speed, noise immunity and electromagnetic compatibility become the main criteria for the quality of electronic design.
Changes in the characteristics of silicon photovoltaic cells of solar arrays after current overloads
Authors: Ivanchenko A. V. , Tonkoshkur A. S.
Published: October 2019

Recently, much attention has been paid to the study of the influence of current overloads and local overheating on the degradation of the electrical characteristics of the photovoltaic components of solar arrays. First of all, it is connected with the tasks of increasing the reliability and durability of the operation of such renewable sources of electrical energy. Such studies are of particular interest due to the recent emergence of new methods and devices for improving the reliability of solar arrays by isolating inactive (defective or shaded) areas of their photovoltaic components (photovoltaic cells and photovoltaic modules).
This paper presents the research results on the influence of current overloads on the current-voltage and volt-watt characteristics and the electrical parameters of photovoltaic cells of solar arrays based on monocrystalline silicon.
The testing was performed using the cyclic current overload mode, which is the flow of electric breakdown current passed through the back-turned diode of a photovoltaic cell for several seconds. After that, the photovoltaic cell was cooled to room temperature, and then its current-voltage and volt-watt characteristics were measured.
The degradation (decrease) of all the basic electrical parameters of photovoltaic cells (open-circuit voltage, short-circuit current, filling factor of the current-voltage characteristic, and maximum power) has been established. The additive nature of the changes and the average relative decrease of the indicated electrical parameters for one breakdown cycle are determined. Comparison of the response time range of the PolySwitch fuses with the breakdown durations of photovoltaic cells is performed. The conclusion is drawn about the prospect of using such resettable fuses as protection in emergency situations that are associated with current overloads in solar arrays.

Published: October 2019

Wild tomato species, like Solanum chilense, are important germplasm resources for enhanced biotic and abiotic stress resistance in tomato breeding. S. chilense also serves as a model to study adaptation of plants to drought and the evolution of seed banks. The absence of a well-annotated reference genome in this compulsory outcrossing, very diverse species limits in-depth studies on the genes involved.

We generated ∼134 Gb of DNA and 157 Gb of RNA sequence data for S chilense, which yielded a draft genome with an estimated length of 914 Mb, encoding 25,885 high-confidence predicted gene models, which show homology to known protein-coding genes of other tomato species. Approximately 71% of these gene models are supported by RNA-seq data derived from leaf tissue samples. Benchmarking with Universal Single-Copy Orthologs (BUSCO) analysis of predicted gene models retrieved 93.3% of BUSCO genes. To further verify the genome annotation completeness and accuracy, we manually inspected the NLR resistance gene family and assessed its assembly quality. We find subfamilies of NLRs unique to S. chilense. Synteny analysis suggests significant degree of the gene order conservation between the S. chilense, S. lycopersicum and S. pennellii genomes.

We generated the first genome and transcriptome sequence assemblies for the wild tomato species Solanum chilense and demonstrated their value in comparative genomics analyses. These data are an important resource for studies on adaptation to biotic and abiotic stress in Solanaceae, on evolution of self-incompatibility and for tomato breeding.
The Trithorax Group Factor ULTRAPETALA1 Regulates Developmental as Well as Biotic and Abiotic Stress Response Genes in Arabidopsis
Authors: Tyler Ludmila , Miller Mark J , Fletcher Jennifer C
Published: October 2019

In eukaryotes, Polycomb group (PcG) and trithorax group (trxG) factors oppositely regulate gene transcription during development through histone modifications, with PcG factors repressing and trxG factors activating the expression of their target genes. Although plant trxG factors regulate many developmental and physiological processes, their downstream targets are poorly characterized. Here we use transcriptomics to identify genome-wide targets of the Arabidopsis thaliana trxG factor ULTRAPETALA1 (ULT1) during vegetative and reproductive development and compare them with those of the PcG factor CURLY LEAF (CLF). We find that genes involved in development and transcription regulation are over-represented among ULT1 target genes. In addition, stress response genes and defense response genes such as those in glucosinolate metabolic pathways are enriched, revealing a previously unknown role for ULT1 in controlling biotic and abiotic response pathways. Finally, we show that many ULT1 target genes can be oppositely regulated by CLF, suggesting that ULT1 and CLF may have antagonistic effects on plant growth and development in response to various endogenous and environmental cues.

Published: October 2019

Researches on relevance of financial ratios on stock returns mostly adopt linearity assumptions. This research aims to show the relevance of financial ratios on stock return and to compare the accuracy of linear and  non linear models. Linear and non  linear multivariate regression models are constructed from several financial ratios towards stock return to identify ratios with significant influences and subsequently compared in regard of their determinations. The samples consist of manufacturing companies listed on IDX  from 2009 through 2016 totaling 97 companies. Results of bivariate regressions show consistent relationships exist in form of positive-quadratic relationships for profitability ratios (ROA and ROE) and negative-logarithmic relationships for liquidity and solvability ratios (CR, QR and DER). In general, profitability ratios remain the dominant ratios affecting stock returns

Learning foreign languages, especially Arabic and English at the Imam Bonjol State Islamic University in Padang has been going on for a long time but the results have not been as expected and are seen as not satisfying stakeholders. For this reason, it is necessary to conduct research on the programs that are run based on the need analysis   for training foreign languages. Need analysis is the process of finding gaps between what people know, do, or feel and what they have to know, do, or feel in order to be able to do competently. Therefore, needs analysis is planned and carried out to obtain a number of data or information about conditions and needs. Needs analysis helps organizations and individuals to find solutions. Needs analysis is needed before implementing the program to see gaps or differences between ideal and optimal conditions. The results of the needs analysis inspire the design of the type of program, the objectives and indicators of success, the structure of the program, the material, the evaluation and monitoring system, and the criteria for the participants and relevant resource persons. Through this research, Present Situation Analysis, Target Situation Analysis and Expected Improvements were carried out. From the analysis carried out it can be concluded that the foreign language training that has been conducted has not yet fulfilled expectations and has not been maximized, therefore comprehensive improvements need to be carried out from various sides.
Episcopado católico versus 3º Programa Nacional de Direitos Humanos: Uma análise dos atuais discursos eclesiásticos sobre sexo e reprodução
Authors: Borges Guilherme
Published: October 2019

Resumo: O presente esforço investigativo visa esquadrinhar discursos reproduzidos pelo episcopado católico em oposição ao lançamento do 3º Programa Nacional de Direitos Humanos (PNDH-3). Ao analisar reações do alto escalão da Igreja, procura-se sondar o repertório que pauta a institucionalidade católica em suas intervenções políticas contemporâneas, que dizem respeito, no mais das vezes, ao campo da moralidade, com especial predileção pela moralidade de cunho sexual. Na trincheira contrária ao PNDH-3, bispos chancelaram seus posicionamentos com o uso de justificativas laicas. Iniciativas episcopais revelaram-se respaldadas por uma gramática fundada no jusnaturalismo e na Constituição. Em suma, adotou-se o repertório dos direitos com a finalidade mesma de cercear direitos.

“Pentecostais em movimento por moradia: O caso da "Ocupação do Glória" em Uberlândia (MG)”
Authors: Swatowiski Claudia Wolff , Barbosa Luciano Senna Peres
Published: October 2019

Resumo: Este artigo trata da relação entre a composição de um movimento social por moradia e o pentecostalismo. Partindo de uma pesquisa realizada entre 2015 e 2017 na “Ocupação do Glória”, localizada na cidade de Uberlândia (MG), analisamos como a demanda pelo direito à moradia se entrelaça às dinâmicas e à cosmologia pentecostais. Trata-se de examinar como o pentecostalismo contribui para o estabelecimento das condições de possibilidade das ocupações urbanas, e configura uma imbricação entre luta política e batalha espiritual. Argumentamos que, no caso do Glória, o pentecostalismo potencializa o movimento pela moradia, constituindo uma dimensão relevante de mediação entre ocupantes e coordenação, bem como de acionamentos e contornamentos de referentes morais, embora institucionalmente não se confunda com o movimento social.

Resumo: O artigo apresenta uma análise sobre o processo de construção dos relacionamentos entre as religiões ayahuasqueiras e o Estado brasileiro. Estas religiões utilizam a bebida psicoativa ayahuasca, sendo associadas ao debate público contemporâneo sobre drogas. Ampliando seus direitos, conforme constroem sua legitimidade social elas passam a se afastar do tema das drogas. A conquista do direito do uso religioso da ayahuasca e a possibilidade de inclusão deste tema nas políticas culturais do Estado brasileiro são expressões das escolhas, estratégias e projetos políticos das religiões abordadas no presente artigo. Pretende-se traçar algumas comparações entre a política das religiões ayahuasqueiras com a de outras expressões religiosas brasileiras.

Resumo: O PRENACEL é uma pesquisa que incorpora duas abordagens inovadoras para a saúde materna e perinatal: a necessidade de melhorar os níveis de satisfação das mulheres com a experiência do parto; e, a avaliação de impactos do uso de tecnologias de informação e comunicação em saúde. Trata-se de um programa de comunicação via mensagens curtas de textos no celular desenvolvido para gestantes brasileiras atendidas no pré-natal do Sistema Único de Saúde. Nesta análise, pretende-se determinar se o programa contribui positivamente para a percepção das mulheres de sentirem-se melhor preparadas para o parto. Um ensaio aleatorizado por conglomerados foi realizado em 20 unidades de saúde da atenção primária de Ribeirão Preto, São Paulo, entre 2015 e 2016. Dados de entrevista e revisão de prontuários foram coletados de 1210 mulheres. Estes foram submetidos a dois modelos de análise, por protocolo e intenção de tratamento. Receber informações do programa PRENACEL durante a gestação foi associado a um aumento na percepção das mulheres de se sentirem melhor preparadas para o parto, e na percepção de que o pré-natal colabora para que se sintam mais preparadas. Também foram observados impactos positivos no estabelecimento do contato pele a pele e aleitamento materno em sala de parto e no conhecimento sobre intervenções obstétricas. Não foram encontradas diferenças nos demais desfechos maternos e perinatais avaliados, incluindo a satisfação das mulheres com o atendimento ao parto. O PRENACEL pode contribuir com a ampliação do acesso das mulheres a informações que lhes sejam estratégicas para que se sintam mais bem preparadas para a experiência do parto.

Abstract: This paper will report the findings of an education intervention performed by a workshop aimed to provide pregnant women with knowledge about pregnancy, delivery, breastfeeding and newborn care. A cross-sectional study, using a pre and post-intervention research design, was performed with 105 pregnant women from an obstetric service for a two-year period. Time points (pre and post) were compared using either Student t test and ANOVA. Significance was set at p ≤ 0.05. After the intervention all items increased their level from the three stations: antenatal care (20.4%), labor and delivery (36.8%) and postnatal and breastfeeding (32.1%). The total score of the surveys also increased 31.7% when comparing the pre and post applications (p < 0.001). It was evidenced the importance of strategies to improve knowledge about pregnancy and its surroundings to pregnant women. The workshop proposal presented increases in its knowledge and can most likely bring better results in short and long-term outcomes.

Published: October 2019

Objetivo analisar as complicações intra-hospitalares de internação prolongada em pacientes com AVC isquêmico ou ataque isquêmico transitório, internados na unidade de AVC de um hospital terciário. Método trata-se de um estudo correlacional avaliativo. Todos os pacientes com primeira incidência de acidente vascular cerebral isquêmico ou ataque isquêmico transitório admitidos foram analisados retrospectivamente. Durante a internação hospitalar, os fatores preditores de internação prolongada foram: 1) complicações clínicas (pneumonia, infecção do trato urinário, lesão por pressão e trombose venosa profunda), e 2) complicações neurológicas (acidente vascular cerebral isquêmico maligno e transformação hemorrágica sintomática). Resultados 353 pacientes receberam alta no período do estudo. A média de idade foi de 64,1±13,7 anos e 186 (52,6%) eram homens. O tempo médio de internação hospitalar foi de 13,7±14,3 dias. Pneumonia (25,3±28,8 dias, p<0,001), infecção do trato urinário (32,9±45,2 dias, p<0,001) e acidente vascular cerebral maligno (29,1±21,4 dias, p<0,001) aumentaram significativamente o tempo de permanência hospitalar em relação aos pacientes sem quaisquer complicações (11,2±7,1 dias). Conclusão este estudo mostrou que três complicações atrasaram a alta hospitalar em pacientes internados em uma unidade de AVC, duas delas evitáveis: pneumonia e infecção do trato urinário. Medidas mais intensas para evitá-las devem ser incluídas nos indicadores de desempenho para reduzir o tempo de permanência hospitalar nas unidades de AVC.

ABSTRACT: The aim was to determine the spread of genetically similar profiles of Campylobacter in chicken carcasses and evaluate their ability to produce transcripts for ciaB, dnaJ, p19 and sodB genes, before and after cultivation in Caco-2 cells. The strains used were isolated from 420 samples of chicken carcasses chilled and frozen ready for marketing. The species were identified by PCR-multiplex, the phylogeny was determined by RAPD-PCR and the presence of transcripts was performed by RT-PCR. We identified 74 (17.6%) of Campylobacter strains, being 55 (74.3%) C. jejuni and 19 (25.7%) C. coli. The phylogenetic relationship demonstrated heterogeneity between isolates of the same species, with absence of clones, indicating the high level of diversity of circulating genotypes. The gene transcription showed conflicting results before and after the culture in Caco-2 cell, so that before cultivation isolates showed greater capacity to transcribe genes related to survival and after the interaction with human cells, the strains showed higher potential to transcribe genes associated with virulence. The result of this study contributes to the understanding of how these seemingly fragile microorganisms are the most prevalent bacterial agents in human gastroenteritis.

ABSTRACT: The gray scale histogram (GSH) makes it possible to measure the amount and distribution of gray shade frequencies, providing quantitative information on both echogenicity and echotexture of tissues. There is a need to diminish the subjectivity of the ultrasound images of the nuchal ligament (NL). This work proposes to evaluate the NL by ultrasound B-mode GSH images in different ages of Quarter horses. It used 15 healthy Quarter horses, which were classified by age into three different groups: “baby” (1), “sobreano” (2) and “adult” (3). The animals were submitted to chemical restraint for the ultrasound examination. Subsequently, the GSH tool was used in each image for statistical analysis. There was a significant difference between Mean and Mode between groups. Group 1 differed significantly when compared to Group 2 and 3. Group 2 presented superior echogenicity to Group 1 and 3. The height of the NL did not vary considerably between groups. GSH indicated that the echogenicity of NL in Quarter horses varies with age.

Published: October 2019

ABSTRACT This study aimed to verify the applicability of using MODIS-EVI sensor time series for land use and vegetation cover mapping in the Pampa biome, Rio Grande do Sul state, Brazil. The study period comprised the months from June 2013 to June 2014. The procedures included the use of MODIS Sensor images, altimetric data and nighttime images, associated with a hierarchical decision tree classifier, constructed using the C4.5 algorithm. The proposed approach stems from the consideration that the study area has varying characteristics and, therefore, should be treated simultaneously by different and intuitive classifiers, which justifies the choice of decision tree. To evaluate the results, reference data acquired from Landsat 8-OLI satellite images and IBGE data were used. The classification using the MODIS time series showed a global accuracy of 90.09% and Kappa index of 0.8885. When compared to the IBGE reference data, the Soybean class obtained a correlation coefficient of 0.94, the rice class obtained 0.97 and the silviculture class obtained the lowest value, 0.78. The highest spectral similarities were found in the vegetation cover classes, such as grassland, forest and silviculture. Therefore, with the use of multitemporal data from the MODIS sensor, combined with the use of altimetric data and nighttime images, it is possible to generate a land use and vegetation cover map for the Pampa biome with an acceptable accuracy, considering the MODIS sensor resolution limitations.

ABSTRACT Nitrogen exerts a marked influence on the yield and quality of the onion. The present work was developed from June to October 2016, aiming to evaluate the yield and quality of two cultivars of onion under a system densified as a function of nitrogen doses in Mossoró, RN, Brazil. A randomized block design was used in a 2 x 7 factorial scheme, with four repetitions, corresponding to two cultivars (IPA 11 and Rio das Antas) and seven nitrogen doses (0, 45, 90, 135, 180, 225 and 270 kg ha-1 of N), provided by fertigation, with four repetitions. The dose of 92 kg ha-1 of N provides the highest total and marketable yields of bulbs. Nitrogen fertilization increases the concentrations of N, chlorophyll a, b and total in the leaves of the onion, as well as the percentage of bulbs of classes 3 and 4 and the pungency, reducing the percentage of bulbs of class 2 and non-commercial. The doses of 108 and 82 kg ha-1 of N provide the highest rates of return for ‘IPA 11’ (R$ 2.07) and ‘Rio das Antas’ (R$ 2.41), respectively.

Published: October 2019

ABSTRACT The characteristics of materials used in packages for seed storage may have a negative influence in the deterioration process, causing future problems during the period of storage and in emergence in the field. In this study, the objective was to evaluate the physiological quality of soybean seeds, stored in different packages with and without the addition of CO2 (modified atmosphere), for different periods of storage and in uncontrolled environmental conditions. In order to carry out the experiment, a completely randomized design was used in a split-plot scheme, with three types of packages (permeable, hermetic package inside the permeable package and hermetic package inside the permeable package with CO2 injection) in the main plot and six storage periods (zero, 45, 90, 135, 180 and 225 days) in the subplot, with four repetitions, totaling 72 experimental units. In hermetic packages multi-layer paper was used with or without CO2 injection, stored them for 225 days and performed an assessment at regular intervals of 45 days. At each period, the seeds were submitted to tests for moisture content, germination, seedling emergence, accelerated aging and electrical conductivity. The hermetic package, with and without CO2 injection, decreases the speed of deterioration of soybean seeds. The hermetic package allows a higher physiological quality of soybeans compared to the permeable package, with a storage period of up to 180 days under uncontrolled environmental conditions. The addition of CO2 inside the hermetic packages favors the maintenance of the physiological quality of soybean seeds in storage.

Published: October 2019

RESUMO Investigamos as representações sociais dos professores do curso de Medicina de uma universidade no litoral norte de Santa Catarina quanto à abordagem de pessoas com hipertensão arterial sistêmica (HAS) na prática clínica. Realizamos uma pesquisa qualitativa, utilizando entrevistas semiestruturadas para a coleta de dados com oito docentes do curso em uma amostragem de conveniência, representando as grandes áreas envolvidas no internato médico. Os dados foram analisados conforme a metodologia do Discurso do Sujeito Coletivo, usando como operadores as idéias centrais e expressões-chave. Verificamos que as pessoas com hipertensão chegam aos profissionais de diversas formas: a partir de um achado no exame físico realizado por outros motivos, na revisão de saúde por questões preventivas, em situações de urgência, referências ou com queixas que a pessoa atendida relaciona à pressão arterial elevada. Os docentes identificaram falta de associação entre a HAS e sintomas, atribuindo tal associação às pessoas acometidas, ainda que o discurso dos próprios sujeitos tratasse a HAS como doença mais do que como fator de risco. A má adesão ao tratamento surgiu como limitação das medidas não farmacológicas e farmacológicas, evidenciando-se a dificuldade de justificar as mudanças exigidas na vida das pessoas para lidar com um risco que não se traduz em illness na ausência de complicações associadas. Sugere-se a importância de definir de forma adequada a HAS como um sinal vital e fator de risco na graduação médica, a fim de evitar a promoção da doença e abordar de forma efetiva o problema por meio de um Plano de Manejo Conjunto quando as intervenções se fizerem necessárias.

RESUMO Introdução A Educação Baseada na Comunidade (EBC) no contexto da formação de profissionais da saúde não é um conceito novo, pois sua origem data da década de 1970. Porém, ao longo dos anos, o modo como a EBC é aplicada na educação médica vem sofrendo transformações. No Brasil, desde 2001, a EBC foi incorporada às diretrizes curriculares dos cursos de graduação da área da saúde e, mais recentemente, em 2014, na publicação das novas diretrizes dos cursos de graduação em Medicina. Objetivos Os objetivos do estudo foram levantar os sentidos e significados que os professores atribuem à Educação Baseada em Comunidade nas matrizes curriculares em vigência no ensino médico da Uniceplac no ano de 2016 e identificar possibilidades de aprimoramento do ensino na instituição em consonância com as diretrizes nacionais em vigência. Método Estudo de caráter qualitativo, realizado no Centro Universitário do Planalto Central Apparecido dos Santos (Uniceplac). Os dados foram coletados por meio de entrevista reflexiva com 13 docentes que estão ou estiveram diretamente ligados à EBC nessa instituição no ano de 2016. O método de análise de dados foi a Análise de Conteúdo de Bardin, com a utilização do software Atlas-ti 7 para o suporte na análise. Resultados Os resultados demonstram que a maioria dos docentes afirma conhecer o conceito de EBC, mas sua compreensão diverge da literatura. Além disso, os docentes indicaram falhas na carga horária, nas relações dos professores entre si e com a coordenação, no planejamento e na conquista de cenários adequados das disciplinas ligadas à EBC, além de desafios macropolíticos de aplicabilidade da EBC nos cenários do Sistema Único de Saúde (SUS). Estes resultados estavam relacionados à burocratização das parcerias e a uma falta de corresponsabilidade entre professor, instituição de ensino e Estado. Conclusão Como a EBC vem sendo incorporada gradativamente à educação médica, as instituições também têm uma necessidade crescente de transformação e adequação às diretrizes curriculares vigentes. Sugere-se uma capacitação permanente do corpo docente sobre a compreensão e aplicação da EBC, bem como a criação de um órgão, setor ou funcionário destinado apenas à institucionalização, formalização e manutenção dos cenários, destacando-se cenários da atenção básica no SUS. É também essencial instruir os alunos sobre o tema, para que possam compreender a aplicabilidade da EBC, sua importância na formação médica e sua contribuição para a melhoria da qualidade de vida da população.

ABSTRACT Background Medical schools all around the world are engaged in curricular reforms aimed at fostering patient- and learner-centeredness, implementing curricular transformations in order to counterbalance the erosion of humanistic and professional values and the loss of idealism of recent graduate physicians. In Brazil, medical schools are facing the challenge of redesigning medical curricula towards more learner-centered and patient-centered approaches, stimulated by recent national medical education guidelines. However, desirable outcomes towards medical education have not been fully achieved. Aim To access medical students’ attitudes and determine predictors of medical students’ patient-centered attitudes among students from different curricular designs (traditional, innovative and advanced). Methods Medical students from 1st to 6th year from 21 Brazilian medical schools participating in the project for evaluating change and trends proposed by the Brazilian Association of Medical Education, with different stages of curricular designs (traditional, innovative and advanced), answered the Brazilian version of the Patient–Practitioner Orientation Scale (B-PPOS) and a questionnaire with curricular and sociodemographic variables. Results Brazilian medical students care more than they share information, power and responsibility (p < 0.001; d = 0.599). They are more concerned with the psychosocial context than with patient’s perspective (p < 0.001; d = 0.797) and share more power and responsibility than understanding (p < 0.001, d = 0.455). Female gender (B = 0.180), students from public schools (B = 0.132), year of medical training (B = 0.021), preference for future medical practice in public services (B = 0.053) and extracurricular activities (B = 0.068) were predictors of patient-centered attitudes among medical students (p < 0.05). Meanwhile, the father’s educational level and choice to study surgical specialties (p < 0.05) were predictors of less patient-centered attitudes among students. Different curricular designs were not associated with students’ patient-centered attitudes (p > 0.05). Conclusion tant predictors of patient-centered attitudes among medical students. Further research should investigate the direct influence of faculty professionalism development programs on students’ patient centered-attitudes.

RESUMO O curso de Medicina da Universidade Federal do Pampa desenvolve-se sob pilares transformadores e vanguardistas da metodologia ativa. O curso transcende as práticas e educação biomedicalizadoras tradicionais por meio do reconhecimento dos aspectos humanos e sociais da medicina, em busca de uma formação centrada na visão holística do cuidado, preconizando um Serviço de Saúde público de qualidade. Além disso, a formação médica do Pampa traz à tona a necessidade de valorizar a autonomia do estudante, por meio de atividades que promovam a reflexão crítica e a aplicabilidade em situações reais dos temas propostos pelos docentes, valorizando ainda a articulação em grupo para diálogo, construção de ideias e resolução de problemas. A apropriação e aplicação de metodologias ativas em ambientes de promoção de saúde contribuem, portanto, para esse ideal de formação. Nessa perspectiva, este estudo consiste em um relato de experiência de abordagem crítico-reflexiva de acadêmicos do quarto semestre do curso de graduação em Medicina da Universidade Federal do Pampa (Unipampa). O estudo se refere ao componente de Práticas de Integração Ensino, Serviço e Comunidade (Piesc) do Núcleo de Prática Profissional (NPP) no período de abril a junho de 2018 e se trata de uma atividade proposta com o objetivo de compartilhar a vivência desses estudantes na construção e execução de uma atividade para o Programa de Saúde na Escola (PSE) vinculada a uma das Estratégias de Saúde da Família (ESF) de um município da fronteira oeste do Rio Grande do Sul. O assunto promovido pelos alunos foi escolhido por ser fundamental à prática de uma medicina com foco na prevenção de agravos e ainda assim pouco discutido devido à delicadeza do tema: saúde sexual. A atividade foi proposta com base teórica centrada no Aprendizado Baseado em Equipes (Team-Based Learning – TBL), destacando o autoconhecimento, prevenção contra infecções sexualmente transmissíveis, empoderamento no quesito de direitos sexuais e reprodutivos e o consentimento sexual. Foi realizada uma análise dialética das discussões com o propósito de avaliar as atividades realizadas, (re)significar as vivências e compilar as expectativas e impressões acerca da experiência

Abstract Objective: To analyze the knowledge, potentialities and barriers related to the implantation of the Kangaroo Method in the perception of nurses who work in the maternal-infant units of a school hospital. Method: An exploratory-descriptive research with a qualitative approach, guided by the Policy of Humanized Attention to the Low Weight Newborn, Kangaroo Method. Held between January and March 2018, with eight nurses from a maternal-infant unit. Data was collected between January and March 2018, through semi-structured interviews, transcribed and submitted to Thematic Content Analysis associated with Atlas Ti version eight resources. Results: Three categories emerged: Barriers to the development of the Kangaroo Method; Knowledge about the Kangaroo Method; and Potentialities of the Kangaroo Method. Conclusions and implications for practice: The nurses' speeches revealed partial knowledge, lack of practical experience and barriers related to team resistance and lack of institutional support, although they considered the method with potential benefits to provide bonding and indicate continuing education as a necessary strategy for its implementation.

ABSTRACT BACKGROUND: Liver transplantation is the main therapeutic alternative for patients with advanced liver disease. These patients have high prevalence of psychiatric comorbidities that may negatively interfere in clinical outcomes and quality of life. It is not clear in the literature whether the different etiologies of hepatic disease have the same prevalence of psychiatric disorders. OBJECTIVE: The aim of this study was to investigate whether patients in the liver transplant list showed differences in psychiatric characteristics, medical variables and quality of life among different etiological groups. METHODS: This is a cross-sectional study that evaluates quality of life, psychiatric and clinical comorbidities through the application of validated questionnaires and instruments in 248 patients who were on transplant waiting list from 2010 to 2014, assisted in a University Hospital and in a Private Hospital in Salvador/Bahia, Brazil. The patients were evaluated through the Mini International Neuropsychiatric Interview (M.I.N.I. PLUS 5.0) and Medical Outcomes Short-Form Health Survey (SF-36). RESULTS: The etiology of the most prevalent liver disease was hepatitis C virus. A prevalence of 50.8% of at least one mental disorder was identified. When alcohol abuse/dependence was excluded, the prevalence was 25.8%. Mental health did not show a statistically significant difference in the diverse etiological groups, but a higher prevalence of psychiatric comorbidities was detected among women and younger than 40 years. No cases of psychotic disorders were detected, possibly by exclusion prior to listing. There was no difference in the quality of life domains in the different liver etiological groups. CONCLUSION: A high-prevalence of psychiatric disorders was found among all clinical conditions most associated with indication for liver transplantation. Attention is drawn to the absence of patients with psychotic disorders, which suggests that transplantation may not have been indicated for this group of patients. For these reasons, professionals caring for liver transplant candidates should be highly vigilant for the presence of mental disorders, regardless of the etiology of liver disease. Specialized care is recommended to minimize the early exclusion of patients with no other therapeutic possibilities, as well as care of all people with mental disorders.

Resumo A rede pública municipal de ensino do Rio de Janeiro desenvolve práticas de mídia-educação desde os anos 1980. A pesquisa a que se refere este artigo teve como objetivo analisar características e abrangência dessas práticas e possíveis relações destas com diretrizes formuladas pela SMERJ para o setor. Foi realizada, em primeira etapa, através de questionários, junto a gestores(as) das 1009 escolas de ensino fundamental; na segunda etapa, foram feitas visitas a oito escolas, com práticas mídia-educativas diversificadas, com observações e entrevistas; por fim, foi realizada análise de documentos da SMERJ, nos quais se encontram diretrizes propostas para as práticas mídia-educativas nas escolas. Em razão da extensão dos dados produzidos, o artigo aborda os resultados da análise dos questionários, em articulação com a análise documental. Os resultados indicam que a mídia-educação está presente em mais de 90% das escolas da rede, prevalecendo amplamente práticas de análise de conteúdos de produtos das mídias de massa (materiais audiovisuais; textos do jornalismo on-line; telejornalismo) e, em menor escala, de conteúdos de redes sociais. A produção de mídias, prática importante na perspectiva da mídia-educação, é pouco usual nas escolas, assim como o uso de TIC nas práticas pedagógicas. Os resultados indicam que as propostas formuladas pela SMERJ para essa área, nos anos 1990 (sob influência das diretrizes para a media education, sistematizadas pela Unesco), estão fortemente presentes nas práticas escolares. No entanto, as novas formulações desse campo, embora integrem diretrizes mais recentes da política educacional da Secretaria, não integram ainda o cotidiano escolar.
