ENSINO SUPERIOR E SOCIEDADE BRASILEIRA: ANÁLISE HISTÓRICA E SOCIOLÓGICA DOS DETERMINANTES DA EXPANSÃO DO ENSINO SUPERIOR NO BRASIL (DÉCADAS DE 1960/70)

O trabalho é resultado de uma pesquisa teórica, documental e histórica sobre a expansão do ensino superior brasileiro nas décadas de 1960 até meados de 1970. Especificamente, objetivou demonstrar como e de que forma se deu o processo de expansão do ensino superior e seus determinantes políticos, econômicos e sociais, além de analisar as causas sociais do aumento da pressão pelo acesso ao ensino superior. Para tanto, o trabalho está baseado na obra de diversos autores brasileiros sobre o ensino superior e sobre a formação social brasileira no período, além da análise de documentos e legislação específica sobre o ensino superior. Conclui que as transformações ocorridas na sociedade brasileira a partir de meados da década de 1950 levam as camadas médias, mais que qualquer outra classe, a elevar a pressão pelo acesso ao ensino superior. Tal pressão das camadas médias vai, no contexto político aberto pelo golpe militar de 1964, dar base social ao movimento estudantil, que figura como principal foco de contestação política da ditadura. A expansão do ensino superior, que se deu no processo da reforma universitária de 1968 e nos anos seguintes, levada à cabo pela ditadura militar, determinou modificações administrativas que já estavam presentes nas reivindicações dos estudantes, assim como já vinham sendo colocadas em prática em instituições como o ITA e a UNB, ao mesmo tempo que promoveu o ensino superior privado, baseado na multiplicação dos cursos e estabelecimentos isolados, com a intenção principal de conter o movimento estudantil e impedir a passagem das camadas médias ao campo da oposição, o que auxiliou na conquista da hegemonia possível na sociedade brasileira.(AU)

Determinação da concentração de metais no material particulado (PM10 e PM2,5) do ar atmosférico em uma área urbana da cidade do Natal – RN

This study aimed to assess ambient air quality in a urban area of Natal, capital of Rio Grande do Norte (latitude 5º49'29 '' S and longitude 35º13'34'' W), aiming to determine the metals concentration in particulate matter (PM10 and PM2,5) of atmospheric air in the urban area o the Natal city. The sampling period for the study consisted of data acquisition from January to December 2012. Samples were collected on glass fiber filters by means of two large volumes samplers, one for PM2,5 (AGV PM 2,5) and another for PM10 (PM10 AGV). Monthly averages ranged from 8.92 to 19.80 g.m-3 , where the annual average was 16,21 g.m-3 for PM10 and PM2,5 monthly averages ranged from 2,84 to 7,89 g.m -3 , with an annual average of 5,61 g.m-3 . The results of PM2,5 and PM10 concentrations were related meteorological variables and for information on the effects of these variables on the concentration of PM, an exploratory analysis of the data using Principal Component Analysis (PCA) was performed. The results of the PCA showed that with increasing barometric pressure, the direction of the winds, the rainfall and relative humidity decreases the concentration of PM and the variable weekday little influence compared the meteorological variables. Filters containing particulate matter were selected in six days and subjected to microwave digestion. After digestion samples were analyzed by with Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The concentrations for heavy metals Vanadium, Chromium, Manganese, Nickel, Copper, Arsenic and lead were determined. The highest concentrations of metals were for Pb and Cu, whose average PM10 values were, respectively, 5,34 and 2,34 ng.m-3 and PM2,5 4,68 and 2,95 ng.m-3 . Concentrations for metals V, Cr, Mn, Ni, and Cd were respectively 0,13, 0,39, 0,48, 0,45 and 0,03 ng.m-3 for PM10 fraction and PM2,5 fraction, 0,05, 0,10, 0,10, 0,34 and 0,01 ng.m-3. The concentration for As was null for the two fractions

Aplicação da destilação simulada por cromatografia gasosa e da termogravimetria para a avaliação da influência da redução do teor de enxofre sobre as propriedades físico-químicas do óleo diesel

One of the main problems related to the use of diesel as fuel is the presence of sulfur (S) which causes environmental pollution and corrosion of engines. In order to minimize the consequences of the release of this pollutant, Brazilian law established maximum sulfur content that diesel fuel may have. To meet these requirements, diesel with a maximum sulfur concentration equal to 10 mg/kg (S10) has been widely marketed in the country. However, the reduction of sulfur can lead to changes in the physicochemical properties of the fuel, which are essential for the performance of road vehicles. This work aims to identify the main changes in the physicochemical properties of diesel fuel and how they are related to reduction of sulfur content. Samples of diesel types S10, S500 and S1800 were tested according with the methods of the American Society for Testing and Materials (ASTM). The fuels were also characterized by thermogravimetric analysis (TG) and subjected to physical distillation (ASTM D86) and simulated distillation gas chromatography (ASTM D2887). The results showed that the reduction of sulfur turned the fuel lighter and fluid, allowing a greater applicability to low temperature environments and safer for transportation and storage. Through the simulated distillation data was observed that decreasing sulfur content resulted in higher initial boiling point temperatures and the decreasing of the boiling temperature of the medium and heavy fractions. Thermogravimetric analysis showed a loss event mass attributed to volatilization or distillation of light and medium hydrocarbons. Based on these data, the kinetic behavior of the samples was investigated and it was observed that the activation energies (Ea) did not show significant changes throughout conversion. Considering the average of these energies, the S1800 had the highest Ea during the conversion and the S10 the lowest values

Avaliação do impacto socioambiental de indústrias têxteis no rio Jundiaí - Macaíba/RN/Brasil

The contamination of aquatic environments is a phenomenon that dates back the origins of human civilizations and was amplified by the advent of industrial processes. The Jundiaí river , Macaíba's main water source, suffering discharge of effluents from various industries. The study work´s in two fronts, the environmental perception front was conducted through semistructured interviews whose textile effluent was appointed by the population as the main problem in the river. It was observed that nearly all respondents had concerns about the environment. In addition, there is an inclusion of individuals as the cause of the problem, because a significant part recognizes that its activities may cause damage to the environment and people's health. In other front, the experimental monitoring of water quality was conducted through ecotoxicological tests and physiochemical analysis that proposed to assess Pomacea lineata .Mysidopsis juniae isolated effect of textile effluent and its influence on the river compared with the limits established by Brazilian law. Although the physio-chemical analysis shows is inconclusive about the participation of the textile effluent in environmental contamination of the river, the ecotoxicological tests have shown to blunt the signal that the effluent may present a risk to aquatic organisms and consequently to human health. Thus, an interdisciplinary way it was possible to study the cause of the environmental problem identified by the population in the realization phase and measurable effect on water quality analysis in the river by means of the tests mentioned.

Estimulação transcraniana por corrente contínua (ETCC) sobre o córtex motor na modulação autonômica em pessoas com lesão medular com diferentes graus e níveis de lesão

Introduction: Transcranial Direct Current Stimulation (tDCS) has been used in studies for the treatment of chronic pain, but their effects on the autonomic nervous system (ANS) are non-existent. Therefore, the need for studies is of fundamental importance, as these individuals have autonomic imbalance and the intensity of this is dependent on the degree and level of injury. Objective: We investigated the effect of tDCS on the ANS in people with spinal cord injury (SCI) with different degrees and levels of injury. Methods: Randomized, placebo-controlled, double-blind, applied anodal tDCS or sham on the primary motor cortex (M1), bilaterally. The subjects (lower incomplete injury, n = 7; lower complete injury, n = 9; and high complete thoracic injury, n = 3) visited the laboratory three times and received active or sham tDCS for 13min. The heart rate variability (HRV) was measured before, during and after stimulation and analyzed the variables LF, HF and LF / HF. Results: The tDCS modulated the ANS in different ways among the groups. In individuals with SCI high complete thoracic the tDCS did not change the HRV. However, for individuals with SCI low incomplete, tDCS changed the HRV in order to increase sympathetic (LF, p = 0.046) and reduced parasympathetic (HF, p = 0.046). For individuals SCI low complete to tDCS changed the HRV reduction sympathetic (LF, p = 0.017) and increased parasympathetic (HF, p = 0.017). Conclusions: The present study suggests that anodal tDCS applied on the motor cortex bilaterally could modulate the ANS balance in people with spinal cord injury and that this effect is dependent on the degree and level of injury.

Diagnóstico da comercialização de produtos da medicina popular em feiras livres do semiárido do Rio Grande do Norte: avaliações socioeconômicas e sanitárias, com proposta de legislação específica

Historically, man has empirically acquired knowledge about the therapeutic applications of extracted elements of the natural environment in which belonged. Such knowledge over time culminated in the formation of traditional health systems. Among its features, the use of bioactive plant species - medicinal plants - stands out for its efficiency and high popular acceptance. Despite its importance for public health, the population still has in the open-air fairs the main source for the acquisition of the species used. In these spaces, the trade generally occurs informally, under unfavorable conditions to the quality of the products and to the financial sustainability of the business. In this context, this study aimed to characterize the socioeconomic, cultural and sanitary aspects related to the trade of medicinal plants in municipalities of a semiarid region of Rio Grande do Norte, and additionally, proposing a specific legislation to the activity. Socioeconomic data were collected through on-site interviews, guided by structured form. The observations about the hygienic and sanitary adequacy of physical facilities and practices employed at the point of sale /environment were conducted and recorded with the use of assessment tool developed for use in open markets. The adequacy of medicinal plants to consumption was determined by microbiological analysis. The activity was carried out by individuals who are aged between 21 and 81 years of age, low educational level and low-income, predominantly males. The data showed a tendency to extinction of the activity in all the districts studied. It was observed in all the fairs studied hygiene and sanitation inadequacies that characterized very high health risk, representing in this way, the high probability of Food Transmitted Diseases outbreaks Such conditions were reflected in the high percentage of inadequacy to the consumption of the analyzed medicinal plants samples, illustrating the potential health risk to consumers. To contribute to the correction of hygiene and sanitation inadequacies observed in the studied open-air fairs, educational interventions were made to the training of traders in Good Practices. As a complement, was drafted a specific legislation for the marketing of folk medicine's products in open-air fairs. Such actions, products and its developments will contribute significantly to improving the quality of products available to the population and the preservation of activity, potentially reducing the risks to public health.

Abordagem da ergonomia para avaliação do treinamento simulado das equipes de resposta à emergência em lançamentos de veículos aeroespaciais

This dissertation introduces a study that aims to analyze the simulated training of emergency teams and proposes recommendations for the current training system in order to improve the collective skills and resilience of these teams when facing possible critical situations, triggered by possible accident occurrences during aerospace vehicle launching operations in the Barreira do Inferno Launch Center in Parnamirim / RN. This is a field, exploratory, descriptive, explanatory, and a case study with a qualitative approach. Therefore, we adopted the ergonomics approach, using the situated method of ergonomic work analysis (AET), combining observational and interactive methods. The relevance of this research is characterized by the contributions to minimize the human and material hazzards resulting from possible accidents in these operations, the scientific contribution of the AET for simulated emergency training analysis in the launching operations of aerospace vehicles - which are complex and involve risk of accidents - and consequently, the scientific contribution to the current process of recovering the Brazilian Space Program. The survey results point to problems of various kinds in the current simulated training system which compromise the safety of the operations. These problems are grouped into four categories: technological, organizational, team training and from the activity itself, regarding more specifically communication and cooperation (among the team members and these ones with other sectors involved in the launching operation) and regarding the coordination of actions. We propose: a) a new training model, from the creation and application of scenarios based on postulated abnormalities, which could simulate real critical situations, in order to train and improve the skills of the emergency response teams especially in terms of communication, coordination and cooperation; b) restructuring and reorganizing the current training system, based on the formal establishment of a managing staff, on the clear division of responsibilities, on the standardization of processes, on the production of management indicators, on the continuous monitoring, on the feedback from trainees about the quality of the training and on the continuing and frequent training of emergency teams.

As raízes históricas da política criminal na legislação e nas práticas de atendimento ao adolescente em conflito com a lei

This thesis investigates the historical influence of the criminal policy in the context that shapes the first specific law for children and adolescents in Brazil, the 1927 Children's Code, a standard that inaugurates the conceptual scission between children and "minor" and their different treatment by the State. The study addresses the demand for order in the context of changes in the working world in the transition from the slave system to the capitalist mode of production, and the corresponding disciplinary and punitive control mechanisms directed to the segment of childhood and adolescence. The theoretical route proposes a questioning of the political construction of law and justice, as well as the conformation of the punitive techniques, and the construction of the stereotype of the "delinquent", prime target of the criminal policy, focusing on the process of criminalization of the segment in question through the confrontation of the Critical perspective with the approaches of Classical and Positive schools. This research shows the imposition of a bourgeois morality that obscures the social conflict attributing it to people isolated by the criminalization of their conduct; and points out that the historical forms of selective social control were greatly influenced by psychiatry and psychology, either by the elaboration of the image of the "delinquent" or by the expected performance of custodial institutions. Finally, the developments and the permanence of the historical roots of the criminal policy are problematized, relating them to the difficulties currently encountered in the consolidation of the legal garantism paradigm proposed by the Children and Adolescent Statute.

A prescrição de medicamentos por enfermeiros na atenção primária à saúde no Brasil: caracterização, normatização, formação e lições aprendidas.

O papel do enfermeiro como prescritor vem se ampliando em muitos países nos últimos anos, em diferentes situações e amplitudes de ação, se configurando como prática avançada na enfermagem. No Brasil, a prescrição de medicamentos por enfermeiros está prevista na Lei do Exercício Profissional desde 1986, e permite a esse profissional, a prescrição de medicamentos estabelecidos em programas de saúde pública. Esse estudo tem como objetivo geral analisar as determinações e perspectivas da prescrição de medicamentos por enfermeiros nos protocolos da Estratégia Saúde da Família. Os objetivos específicos são: apreender a atual situação internacional da prescrição de medicamentos por enfermeiros em comparação a essa prática no Brasil identificando semelhanças e diferenças; identificar os contornos legais e normativos da prescrição de medicamentos por enfermeiros no Brasil apontando sua história, tendências e desafios; caracterizar o modelo de prescrição de medicamentos por enfermeiros nos protocolos de Atenção Primária à Saúde no Brasil; investigar possíveis lacunas entre formação, capacitação, autoavaliação e prática da prescrição de medicamentos na Atenção Primária à Saúde na perspectiva do enfermeiro. Trata-se de Estudo de Caso Exemplar com abordagem qualitativa através de Revisão Bibliográfica, Análise Documental e Grupo Focal com enfermeiros. A análise dos dados deu-se por meio da Análise de Conteúdo e Análise Qualitativa de Conteúdo. Os resultados revelam que a categoria da enfermagem contribuiu para a legalização da prescrição, porém não para a sua legitimação; na Atenção Primária à Saúde, essa atribuição está consolidada por meio de protocolos e legislação, embora sem estratégia clara de acompanhamento pelo Ministério da Saúde; observa-se resistência em algumas normatizações dentro do setor saúde. Quanto aos protocolos, observou-se não há exigência de pré-requisitos na maioria deles; há possibilidade de diagnóstico pelo enfermeiro na gravidez, nutrição infantil e doenças sexualmente transmissíveis; observou-se variados graus de autonomia; amplo grupo de medicamentos prescritos por enfermeiros. Dos 37 participantes do Grupo Focal, 97,3% eram do sexo feminino; 54% formados há menos de 10 anos, 27% entre 10 e 20 anos, 16,2% há mais de 20 anos; 83,8% com especialização em Saúde Pública. Todos os enfermeiros relataram insuficiência da disciplina de farmacologia para instrumentalizar a prática prescritiva. Destacou-se a necessidade de pós-graduação; a importância da experiência clínica; falta de discussões e capacitação. Apenas alguns se autoavaliaram como competentes para prescrever, outros revelam medo de reação adversa a medicamentos. Conclui-se que há tendência da prescrição de medicamento por enfermeiros permanecer apenas na legalidade e o principal desafio é alcançar a legitimidade. Confirma-se uma prática prescritiva sem requisitos, diversidade de orientações induzindo a multiplicidade de ações que pode afetar a qualidade da prescrição. Há lacunas entre formação, capacitações e exigências cotidianas da prescrição de medicamentos por enfermeiros na Atenção Primária à Saúde. No Brasil se faz premente pesquisa para avaliar o impacto, a qualidade e a segurança da prescrição de medicamentos por enfermeiros. A experiência internacional sugere também que essa prescrição deve ser apoiada pelo coletivo de enfermeiros, com robusto plano de capacitação nacional, além de governança e apoio local.

Projeto iterativo, simulação, análise e otimização de máquina a relutância variável monofásica

Variable reluctance motors have been increasingly used as an alternative for variable speed and high speed drives in many industrial applications, due to many advantages like the simplicity of construction, robustness, and low cost. The most common applications in recent years are related to aeronautics, electric and hybrid vehicles and wind power generation. This paper explores the theory, operation, design procedures and analysis of a variable reluctance machine. An iterative design methodology is introduced and used to design a 1.25 kW prototype. For the analysis of the machine two methods are used, an analytical method and the finite element simulation. The results obtained by both methods are compared. The results of finite element simulation are used to determine the inductance profiles and torque of the prototype. The magnetic saturation is examined visually and numerically in four critical points of the machine. The data collected in the simulation allow the verification of design and operating limits for the prototype. Moreover, the behavior of the output quantities is analyzed (inductance, torque and magnetic saturation) by variation of physical dimensions of the motor. Finally, a multiobjective optimization using Differential Evolution algorithms and Genetic Algorithms for switched reluctance machine design is proposed. The optimized variables are rotor and stator polar arcs, and the goals are to maximize the average torque, the average torque per copper losses and the average torque per core volume. Finally, the initial design and optimized design are compared.

Dinâmica industrial, emprego e pobreza no Brasil, uma abordagem alternativa

Between 2003 and 2014 Brazil has increased exports by 52%, increased the formal employment and paid employment by 19% and reduced multidimensional poverty by 42%. The purpose of this work is to test the hypothesis that there is a Brazilian Growth Virtuous Circle where these three variables would be connected in order to increase exports and reduce poverty through the salaries transfer of funds. The construction of the hypothesis is made for Export Industry through ideas Verdoorn, Kaldor and Thirlwall presenting the export industry as an engine of economic growth. To present employment acting directly on economic growth is used Wage Led Rowthorn approach. The Capability Approach of Amartya Sen is used to understand the Multidimensional Poverty. The hypothesis was tested using data from the National Household Survey and Aliceweb between 2003 and 2014 with the use of the Generalized Method of Moments and the generation of elasticities between export and employment, employment and poverty, and export and poverty.

Análise da força propulsora do motor de indução linear alimentado com imposição de corrente

This work intent to study the motive power provided by the plane linear induction motor, in a lock condition. It uses a method of imposition of the electric current to the stator via a frequency convertor PWM driven by a refed platform. The reading of the motive power was performed by a load cell using an electronic circuit for reading and conditioning of the signal. Aiming a complete analysis of the linear motor, it was performed a computational modeling that employs all relevant parameters to the study of the locked machine. At the end it was held a theoric-experimental confrontation that evaluated the effectiveness of the proposed method.

Associação entre comprometimento motor, mobilidade e qualidade de vida em crianças com paralisia cerebral espástica, nível I, II e III do Gross Motor Function Classification System

The objective of this study was to verify the association between some mobility items of the International Classification Functionality (ICF), with the evaluations Gross Motor Function Measure (GMFM-88), 1-minute walk test (1MWT) and if the motor impairment influences the quality of life in children with Cerebral Palsy (PC), by using the Paediatric Quality of Life Inventory (PedsQL 4.0 versions for children and parents). The study included 22 children with cerebral palsy spastic, classified in levels I, II, and III on the Gross Motor Function Classification System (GMFCS), with age group of 9.9 years old. Among those who have participated, seven of them were level I, eight of them were level II and seven of them were level III. All of the children and teenagers were rated by using check list ICF (mobility item), GMFM-88, 1-minute walk test and PedsQL 4.0 questionnaires for children and parents. It was observed a strong correlation between GMFM-88 with check list ICF (mobility item), but moderate correlation between GMFM-88 and 1-minute walk test (1MWT). It was also moderate the correlation between the walking test and the check list ICF (mobility item). The correlation between PedsQl 4.0 questionnaires for children and parents was weak, as well as the correlation of both with GMFM, ICF (mobility item) and the walking test. The lack of interrelation between physical function tests and quality of life, indicates that, regardless of the severity of the motor impairment and the difficulty with mobility, children and teenagers suffering of PC spastic, functional level I, II and III GMFCS and their parents have a varied opinion regarding the perception of well being and life satisfaction.
