Education has always been considered by social movements, especially the black movement, as an important playing field to be included in their discussions, as it is understood to be a means of promoting awareness, appreciation and social inclusion. Therefore, the approval of Law no. 10.639 / 2003 and its guidelines, which amended the Education Law (Lei de Diretrizes e Bases, or LDB, in Portuguese), can be considered a new milestone in the history of education in Brazil, because they represent substantial changes that alter the country's educational policy and reflect profound social changes in the way our society is represented. Compulsory education about ethno-racial relations and the history of Afro-Brazilian and African culture in all primary and secondary education reverberates in textbooks and supplementary course material, seen as important tools that play a key role to promote the history, culture and identity of Brazilians of African descent and erradication of prejudices. It is understood that publishers occupy an important space, creating, editing and disseminating textbooks and educational material; in other words, structured spaces that permit the transfer of symbolic capital for the legitimation of discourse and the discussion of topics of interest related to social demands, dictating themes and directing debates. In this context, the objective of this study is to investigate the publishing market in the Brazilian context, identifying how changes in the legal field have impacted its dynamics, starting from theNational Textbook Program and the National School Library Program.

Cervical cancer is the second largest cause of deaths from malignant cancer among women worldwide. Many studies show the importance of the HPV virus in the onset of cervical cancer, but because of the monoclonal nature of this cancer, it is suspected that HPV infection may not be considered the only causal factor responsible for the development of cervical carcinoma. Studies have indicated that EBV may have a role in cooperation with the HPV16 tumor development. Such cooperation could influence the tumor microenvironment by creating a favorable niche for its progression. Cancer cells secrete enzymes that degrade the extracellular matrix (ECM). Such enzymes such as matrix metalloproteinases (MMPs) facilitate cell movement in tissues and induce the activity of growth factors that promote angiogenesis. Among the group of MMPs, MMP-7 seems to have a crucial role in the development of carcinogenesis, since its action has been associated with the cleavage and release of adhesion molecules important. In this sense, this study was performed to establish the relationship between the HPV coinfection / EBV and expression of MMP-7. They were examined immunohistochemically histological slides of cervical lesions biopsies of 60 patients aged 35 to 65 years. The samples were divided into high grade lesion and low grade and evaluated semiquantitatively by scoring system ranging from 0 to +++. Histopathological indexes the degree of injury were established. It observed a statistically significant association between high-grade lesion, the expression of MMP-7 and the presence of the HPV virus, with p = 0.007 at the junction portion squamocolumnar and p = 0.023 in the portion of the ectocervix. This correlation

In Brazil, where social issues arising from the structural inequality of a capitalist society did not lead to configuring a State of Social Welfare at any time in its history and that, moreover, it coexists with extreme levels of wealth concentration, encouraged the question about how, nowadays, this social issue is whether or not considered by occupational therapists. Understanding that occupational therapy is a profession that can direct its interest of study and involvement to the social inequalities and its problematics, and highlighting interventions and therapeutic-occupational propositions that occur with individuals who are on the margins of the social organization, this project made a proposal of research that goes back to the relationship between occupational therapy and the "social issues" in Brazil, focusing on the publications produced by researchers until March 2015, when data collection ended. The survey was conducted from the CNPq Research Groups Directory in the Lattes Platform, where occupational therapists researchers working in the occupational therapy subarea were selected in this directory. Then an assessment was held in their resumes on the same platform in order to gather all its productions in format of articles, books and / or book chapters, so that later those related to the subject studied could be selected. In addition to this source of information, all publications in this area in the two indexed Brazilian journals in the field were gathered. The aim was to bring together the production of researchers in occupational therapy with what has been brought in knowledge dissemination vehicles in the area. The data collected after the application of the inclusion criteria for the study were gathered in 112 texts of 155 different authors. The content thereof permitted to categorize and analyze what was produced in the academic area, allowing the apprehension of the theoretical foundation of the relationship between occupational therapy and social issues in Brazil. It is noteworthy that the productions on the theme intensified from the 2000s, and mostly cover the adult population. What has been proposed by social occupational therapy in Brazil and the authors linked to METUIA Project marks sharply the set of this production. Moreover, it is clear that professionals turn to the demands arising from the social question in Brazil, noting that occupational therapy has indeed tools and resources to do so.

Brazil is a country with a wide range of socais problems that need to be resolved so that it can be considered a developed nation. In this sense many social problems could be studied by public research in order to mitigate social inequality. This research aims to identify and understand the obstacles and possibilities for the formation of the research agenda of the public university demands from the local community. The methodology was qualitative and exploratory, which is outlined in literature and literature. The literature encompassed thematic as science, technology and innovation policy (PCT&I); channels of communication between university and society; social technology; and territorial development. The result of the survey pointed out as an obstacle to the construction of the university agenda based on the demands of local communities PCT&I developed based on international models; political control centered in the hands of a few actors, especially scientists; research agenda aimed at an international science, business or particular demands; lack of communication channels and strategies and exchange of knowledge between universities and local communities; little research on the research agenda of Brazilian scientists. As possibilities the search result pointed adherence by the PCT&I concepts such as: social technology; regional development; solidarity economy; social technology park; sustainable development; and actions as public policy development: municipalities, states (master plan) and urban planning.

Public policy incentives are essential to the effectiveness of environmental law and the preservation of services provided by ecosystems. In this context, Payments for Ecosystem Services –PSE programs remunerate environmental services providers through funds built from the user/polluter pays logic. This study aimed to evaluate the possibility of implementing a PSA program in Pirajibu watershed, Sorocaba -SP, and suggest suitable alternatives for the conservation of water resources in the region. To this end, secondary data were collected on public agencies. In addition, were analyzed pictures from the RapidEye satellite (Ministry of Environment-ME), and with the help of satellite images from Google Earth, processed in Quantum GIS 1.6 software- Open Source Information Systems Finally, field trips were made to verify the information found. The results indicate that there is difficulty identifying possible providers and calculate the opportunity cost of the land, since agriculture is a rare activity in the region. Regarding environmental services, there was a great potential of the Pirajibu –Mirim River for water supply. This watershed has been studied in more detail, its water sources were mapped and some of them diagnosed in macroscopic analysis in the field. The water sources are, for the most part, in particular areas, with water having satisfactory aspects. However, there is the presence of garbage, lack of identification, proximity roads and the lack of environmental compliance expected by the Brazilian Forest Code (Lei nº. 12.651/ 2012). This scenario shows the importance that public policy in Sorocaba-SP considers the recovery and protection of water sources, however, not directly compensating the owner. It is suggested that the model has the forecast works for soil conversation on dirt roads, in addition to a donation of inputs and technical assistance to owners interested in recovery. Also considering the characteristics of relief and zoning of the master plan, it is proposed to establish a Private Reserve of National Heritage - PRNP at the head region of Pirajibu -Mirim River. Finally, it is suggested the implementation of other tax incentive policies in the region, such as property tax reduction in suitable properties with economic and social use.

In the field of nanotechnology, the titanium dioxide (TiO2) has been widely studied for its optical and electrical properties. This oxide is an n-Type semiconductor and is found naturally in different crystalline phases. Recently, this material has attracted much attention as photocatalyst for the electrochemical photolysis of water displaying a high efficiency, chemical stability and a large surface area. Furthermore, for this application has been proposed that the synthesis of TiO2 nanotubes (Nts-TiO2) prepared by anodization are promising. Thus, we aimed to study the correlation between the synthesis - morphological and microstructural properties for the optical properties of Nts-TiO2 prepared electrochemically, using the photoelectrochemical decomposition reaction of water as a reaction target optical properties. For this, the Nts-TiO2 were prepared by anodizing the titanium substrate in Ethylene glycol solutions /water/ ionic liquid (BMIM-BF4), followed by a heat treatment at 450 °C. In this study, we performed a factorial design 23 to: i) evaluate the statistical significance of synthesis variables: applied potential (Eapl), bath temperature (Tbanho) and percentage of water in the electrolyte (%A); and ii) quantify the correlation between synthesis, morphological, microstructural and optical properties of Nts-TiO2. The synthesized nanotubes were characterized by their morphology and photoelectrochemical properties. The characterization by X-ray diffraction indicated characteristic peaks only the anatase phase interest. The band gap determined by the Wood-Tauc method were calculated values near 3.2 eV. The scanning electron micrographs showed the formation of Nts-TiO2 in all conditions of synthesis, with an internal diameter with values between 23 and 65 nm, being statistically significant main effects Tbanho and %A and interactions effects of Eapl -%A. To study the photoelectrochemical properties of the electrodes, linear voltammetry experiments were carried out in the light and dark in 0, 5 M H2SO4 solution, the photocurrent density values obtained in the course showed values up to 300 μA cm-2 at 1.01 V vs Ag/AgCl/KClsat. (Water oxidation potential for the system studied) compared with the response obtained in the dark. With the results obtained, is observed the variability in current density in function of morphological, microstructural and semiconducting properties of Nts-TiO2.

Companies incubators can be considered the center of a relationship network comprised by companies, government agencies, universities and research centers. The support offered to incubated companies was designed to accelerate the implementation of new organizations and make them competitive in the market. Therefore, companies networks inserted in these environments favor the exchange of information and cooperation for use of these resources to the development of new products, thus supporting innovation and business competitiveness. Considering that, the aim of this study was to investigate the social networks and resources of Softnet incubator and their incubated software companies, analyzing the networks, regarding its structure, nodes, connections and flows, and identifing shared resources between companies belonging to Softnet. For this, we interviewed the managers of Softnet incubator and Cubo TI, Onion and NeoInfinito interprises. Our results demonstrated the close relationship between available resources and cooperated social networks, since most available resources drives companies to seek the creation of networks, leading to the perception that cooperation provides benefits that would hardly be achieved in isolation and contributed to the understanding of the organizational environment in which incubated technology-based companies operate and Softnet incubator.

Teachers of students who have special educational needs often complain that, despite their previous training in special education area, it is hard for them to fit their student´s needs properly. Considering these teachers´ demands this study aims to investigate in what ways a continuous formation program, based on the production and analysis of teaching cases in a virtual learning environment / AVA, could foster learning, researching skills and professional development of special education teachers who work in multifunction classrooms. This program was developed according to the training needs of special education teachers who participated in a survey that took place in Maraba-PA from 2011 to 2014. The research was part of the National Network Study of multi-functional resources classrooms in Brazilian public schools (http://www.oneesp.ufscar.br/). This study has a qualitative approach based on the principles of collaborative action research in a social and historical perspective. The participants were twelve teachers of multifunctional resource classrooms and a coordinator of special education in Marabá-PA. The program has six modules and is 120 (one hundred twenty) hours long. It has been developed in a virtual learning environment and its method is based on the production and analysis of teaching cases which contents and themes belong to special education area. Results were organized in different axes, according to its themes, in order to: a) analyze the influence of collective reflection spaces in virtual learning environment on teaching skills of special education teacher b) investigate the effect of production and analysis of teaching cases on learning and professional development of teachers special education teachers, c) evaluate and validate the potential and limits of using teaching cases in a training program for teachers who teach students with special educational needs in multi-functional classrooms. The study comes to the conclusion that use of teaching cases, demanded theoretical and practical knowledge of teacher, who also had to get in touch with contents of legal documents. The creation and analysis of cases attended many training needs of teacher who have joined this research. The program could also improve their performance and teaching skills. In addition, it supports the inclusion of students with special educational needs in regular schools. Although the collaborative research has led to the arrangement of a course created and developed by teachers, this program has its own limits and doesn´t aim to fulfill every necessity of educator who work in special needs education field.

Due to the high capacity of oxygen transfer and versatility, pneumatic reactors have been constantly used in bioprocesses. However, aiming to expand the use of these bioreactors in the industry, as well as increase the understanding of the complex phenomena that occur in these devices, this thesis aimed to evaluate the hydrodynamic, oxygen transfer and shear conditions in three models of pneumatic reactors (bubble column, concentric-tube airlift and split-cylinder airlift) in the scales of 5 and 10 L, using as liquid phase four Newtonian fluids and eight non-Newtonian fluids, and five specific air flow rate (air of 1 to 5 vvm). Related to the hydrodynamic were studied the global gas hold-up (g), the gas hold-ups in the riser (R) and in the downcomer (D), liquid circulation time (tC), superficial liquid velocity in the riser (ULR) and in the downcomer (ULD), and the percentage energy losses in the riser (%ER+%EFR), in the downcomer (%ED+%EFD), and in the bottom (%EB) of airlift reactors. The values of g, R, D, ULR and ULD showed increasing behaviour with increase of air and decreasing behaviour with the kinematic liquid viscosity (L) and the rheologic properties (K e n), and observed the opposite for tC. The higher values of g, R, D and tC were obtained for concentric-tube airlift reactor (ACC) and scale of 10 L. With exception of ULR of Newtonian fluids, the others liquid velocity tests resulted in higher values for split-cylinder airlift reactors (ASC) and scale of 10 L. This result was attributed to the greater driving force (R-D) to liquid circulation obtained in the ASC reactors and the higher energy losses in the riser and in the downcomer observed in the ACC reactors. In the bottom of the airlift reactors, the higher values of %EB were obtained to the ASC reactor. To evaluate the mass transfer were studied, the average bubble diameter (Db), the volumetric oxygen transfer coefficient (kLa) and the terms that compose the kLa, the convective mass transfer coefficient (kL) and the specific interfacial area of mass transfer (aL). With the increase of air, L, K and n, the air bubbles were predominantly coalescent in water, presenting distorted shape, and non-coalescent with spherical/elliptical shape in the other solutions. It was observed a similar behavior between the kLa and aL parameters, which were directly proportional to the air and inversely proportional to the L, K and n. In water, the aL values were lower than glycerol solutions due to the higher Db values observed in this liquid. For the kL, it was observed a decreasing behaviour with the increase of the air in the most solutions. The magnitude of kL values was due mainly the oxygen difusivity in the liquid, and the higher values were observed to the water, following by the non-Newtonian solutions. In general, the higher values of the mass transfer parameters were obtained in the ACC reactor and in the scale of 10 L. The proposed method to the estimate the average shear rate velocity based on Kolmogorov’s theory of isotropic turbulence showed results consistent with the literature relative to the behavior and magnitude of this variable, as well as the results obtained by the analysis of the morphological changes of Streptomyces clavuligerus in two models of airlift reactors and two aeration conditions. Were proposed correlations to predict all evaluated parameters. Were obtained in all cases a good fit with the experimental data, with deviations between the calculated and experimental values below 20%.

This study aims to build a theoretical framework that embase the proposal, creation and implementation of a People's Health Information Center in public libraries and third sector organizations in the communities with socioeconomic vulnerability in São Carlos (SP) and the region as a public communication channel of science among the population through the dissemination and popularization of scientific library collections and information services. This information unit is designed based on the existing literature theory about People's Documentation Centers. The focus of this work is the health information, specifically information on popular health and alternative medicine. Moreover, the epistemological stance advocated to guide the professional practice and librarian policy stance should act on in Popular Health Information Centres follows the ideological line of the Popular Education movement of Paulo Freire, as well as the concept of "organic intellectual" of Antonio Gramsci. Finally are listed some spaces and contexts considered favorable and suitable for the application and development of the proposal. It also points up some theories and methodologies that would be advisable to start a research work of information needs in community health to be met by the Centre.

The main goal of this dissertation is to find movies made in Brazil up to 1950 that can be interpreted as queer. The first chapter explains the meaning of queer and the establishment of Queer Theory. The second chapter focuses on Queer Cinema (as in what is Queer Cinema and how a film can be queer), its key moments and how the historiography was created. The third chapter the focus is on the homoeroticism found in Brazilian society and literature during the first half of the 20th century. We also discuss the current state of affairs regarding Brazilian cinema studies and the lack of essays considering the role of (homo)sexuality in the pictures. The few cases of homosexuality in Brazilian film studies are brought up and we also present some cases of deviant sexuality on Brazilian screens up to 1950. After this, the fourth chapter analyses Poeira de estrelas (1948, Moacyr Fenelon), in which a duo of female singers split after one of them abandons the theater to marry a man. Brasa Dormida (1929, Humberto Mauro) is the main film described in the fifth chapter, as it presents an all-male love triangle. The sixth and last chapter is dedicated to an analysis of Limite (1931, Mário Peixoto), an experimental film with minimal plot, using the concepts of queer authorship.

This research intends to investigate the influence of ideological debate and therefore the internal political struggle in the formulation of Brazilian foreign policy during the democratic period of 1945-1964. It tests the hypothesis that the formulation and implementation of the Independent Foreign Policy, in the early 1960s years, corresponded to the radicalization of the national development project and was the culmination of a instrumentalization process of the foreign policy to the national project, started at least since the second government of Getúlio Vargas (1951-1954). Through the analysis of some documents and texts from Francisco Clementino de San Tiago Dantas, important Brazilian intellectual and politician, we intend to identify concepts, theories and arguments that characterize his political thought as well as its correspondence with the ideas that supported the foreign policy in the period 1950-1960.

Over the last decade, sustainability reporting have gained prominence as a growing practice among organizations around the world, accompanied by the increased popularity and adoption of the Global Reporting Initiative (GRI) framework. This has opened space for studies on the disclosure practices of organizations, resulting in the creation of evaluation methodologies for sustainability reports generally focused on the detail level of the information disclosed. As the GRI guidelines are now the main reference for the preparation of such reports and from January 2016 onwards his fourth generation is mandatory, an appropriate methodology is necessary. Mainly considering a focus hitherto despised, as the compliance with the GRI framework and the reporting of meaningful content to the stakeholders, which can be a good representative of the disclosure practices and performance of the organization towards sustainability. Thus, the study aims to propose an evaluation tool for sustainability reports according to GRI G4 guidelines, in addition the study also seeks to clarify how the GRI framework is being used by organizations, to identify the methodological weaknesses of the other evaluation methods and to analyze the performance of various organizations in the new tool. Through a Systematic Literature Review, the main evaluation methods were raised and, after analysis, the methodological weaknesses have been identified. Then, we first tried to explain how the GRI framework is being used to monitor and report on organizational sustainable practices. Hence, it was analyzed GRI reports of the automotive sector published between 2010 and 2014. Thirteen reports at national level and 76 reports globally were analyzed. After, a questionnaire was applied to researchers from around the world on issues related to evaluation, reports and sustainability, and the results were used to determine the weight of the GRI elements using the Mudge diagram. Therefore, a quick and easy to use evaluation method based on GRI guidelines has been developed and applied for all the 89 analyzed reports. Additionally, the Spearman's rank correlation coefficient and direct comparatives were conducted to identify behavioral patterns in sustainability reporting. The research brings contributions both to the academic area, such as the identification of errors in the reports currently released and present weaknesses in the existing assessment methodologies; and to practice area, once the sustainability report assessment tool is pratical and useful to organizations, stakeholders and the GRI itself.

The Minha Casa Minha Vida Programme (My House My Life) was launched in April 2009 with anti-cyclical objectives, in order to counteract the effects of the crisis triggered by the bursting of the housing bubble in the United States in 2008 (the subprime crisis), which caused consequences for the global economy. The PMCMV, however, reduced attention to the objectives of PlanHab - National Housing Plan, calling for the urgent need to maintain the level of economic activity. After five years of operation, the program is intimately linked to the National Housing Policy, to the point that, in practice, it has replaced it. The amount of produced houses is impressive. The Caixa Econômica Federal, a public bank, as the founding manager of the Housing policies and the PMCMV, attached to the Ministry of Finance, apparently gives priority to economic and financial issues for the approval of projects, to the detriment of the priorities with the quality of the urban environment and housing production. These issues are delegated to small and larger towns, where the PMCMV is realized. Such towns do have the power to make demands of adjustments on the projects, according to their master plans and local regulations. What is found, however, in several towns of São Paulo, is that the projects are usually built in very contradiction to what is expected of a master plan or a democratic urban and housing management, as recommended by the Federal Housing Policies and Plans (PlanHab). This study aims to investigate it, through a case in Araraquara. As we go through a whole process of three PMCMV assemblies for low-income people, we will be able to verify the compliance with the laws and municipal urban guidelines, as well as the urban and social impacts, both for the town and for the population served by the MCMV Programme.

Water is one of the most abundant natural resources on the planet, but at the same time is becoming scarce in both quantity and quality in many regions, causing numerous conflicts. The watershed must be a permeable environment, where water infiltrates the soil and reaches the water table and then can be distributed abundant and continuously. Knowledge of the physical and biological characteristics of the basin influencing the handling and consequently the production of water. This study aimed to characterize the Itanguá watershed to support the management of the National Capão Bonito Forest, SP for conservation of water. This dissertation was divided into chapters: chapter 1 contextualized the issues relevant to this study, in the form of bibliographic review, chapter 2 discussed the hydro-environmental characterization of the basin, chapter 3 identified the vulnerability of Itangua watershed to the floods and the areas to be reforested in the permanent preservation areas, chapter 4 identified the priority areas for soil and water conservation and chapter 5 provides a general conclusion. The first results indicated that 60% of the sources analyzed in situ, were characterized as point while the others were diffuse and according to macroscopic evaluation, 13% of the sources were considered with great, 80% good and 7% with reasonable conservation state. The main negative environmental impacts observed were the presence of both exotic species such as: Boar (Sus scrofa) and Pinus spp. and the absence of native vegetation in the area of permanent preservation. The morphometric analysis showed that the Itanguá watershed is an important site for the conservation of water resources by having more elongated and low tendency to form flooding. Were also found nine different priorities classes of soil conservation practices implementation and six classes for forest restoration in permanent preservation area of waterways. The results provided a characterization of the basin Itanguá and important information, since they contribute to the Flona the management plan of Capão Bonito. All methods used in the study were satisfactory to achieve the proposed purpose.

The use of flavor has become increasingly common in the food and pharmaceutical industry, including menthol and ethyl hexanoate (EH) (main ester passion fruit aroma) has achieved prominence in the industry due to its applications ranges in branches different sectors. Among the various properties that flavorings have, the main one is the volatility and the ease of leaving the environment. In this sense, there is a great interest to seek new mechanisms to increase the aromas of residence time in the array. The present work, looking for encapsulating the aromas of mint and hexanoate Ethyl (EH), through polymeric nanofibers, also studied the influence in the tunnel when the β-cicldodextrin is added to the solution and when the fibers are obtained by different routes electrospinning and spinning blow solution (FSS).After obtaining the polymeric fibers of poly (lactic acid) (PLA) by electrospinning and solution blow spinning techniques, the fibers were characterized by Scanning Electron Microscopy (SEM),Ray Diffraction (XRD), Vibrational Spectroscopy Absorption Infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC) and thermogravimetry (TG / DTG). The release profile was performed for all conditions studied aromas. The results showed the polymer nanofibers, a promising tool for encapsulation of flavorings, may be enhanced by the cyclodextrin. The Solution blow spinning (SBS) techniques and electrospinning were effective to form fibers. SBS methodology originated more homogeneous samples with smaller diameters and without the presence of beads.

A few years ago, several studies have been conducted to transformatio n of raw matter into renewable biodegradable materials, since it is necessary to rethink consumption and rationalize the use of packaging derived from synthetic polymers. Among these raw materials can be detached corn starch produced worldwide, with low cost and high potential for biodegradability. In this paper, aiming a possible application in biodegradable packaging, starch polymeric films were developed using native corn starch with the incorporation of 1 to 4% of fibers sugarcane bagasse from industrial wastes, 2.5, 5 and 10% of castor oil, and 2.5, 5% epoxidized soy bean oil, and modified corn starch films with the incorporation of 1 to 3% fibers sugarcane bagasse, and 2.5, 5 % of epoxidized soybean oil. Some mechanical and thermal analysis for characterization of the films were made. The mechanical p roperties were analyzed by tensile test in Dynamic-Mechanical Thermal Analysis (DMTA) equipment. Among the films tested in tension, they stood the native corn starch films that have the best tensile strength results (1.05 MPa) and elongation at break (77.66%), followed by the native starch containing film 3% fiber (0.81 MPa) and native starch films containing 2.5% epoxidized soybean oil (58.55%). The fractured samples were analyzed by Scanning Electron Microscopy (SEM). Thermal an alysis of all kinds of developed films were made by Differential Scanning Calo rimetry (DSC), Thermogravimetric Analysis (TGA) and Thermogravimetric Analysis Derivative, where the DSC curves showed higher thermal stability for native starch films containing castor oil and epoxidized soybean, in which the thermal decomposition was observed between 270 and 291 o C, being higher than the temperatures of other films , and four stages of degradation for these films, and the others had only three stages of degradation. Native starch films with incorporation o f 3% fiber and 2.5% epoxidized soybean oil were buried in soils incubated for completion of the biodegradability test, and analysis of the emissions o f CO2, CH4, and N2O were performed by gas chromatography, it was possible to observe high CO2 emission rates in the first month of incubation for all films. After 90 days, the films were dug up, and the polymer matrix was completely biodegraded.

In contemporary society, pervaded by media culture, the school permanently interacts with the media and information and communications technologies. In specific regard to science education, teachers and students are in contact with science information and thus representations of science and technology present in the media, either in their everyday lives outside of school, either by intentional inclusion in pedagogical practice. However, consolidated policies for media treatment by educational systems at different levels do not exist in Brazil yet. Among other elements that hinder this consolidation, lack of media education programs in teacher training, especially in undergraduate courses in science, is identified as a major obstacle. Thus, the research reported in this paper seeks to contribute to the transformation of this scenario, through the understanding of how students pursuing a licentiate degree in Biology, Physics and Chemistry relate to the media and what their expectations for the insertion of media productions at school are. In order to achieve this objective, we analyzed textual productions developed by these students within a course about the the use of science diffusion media productions in science education, in the light of a media education framework that, with contributions of Critical Theory and Cultural Studies, supports the relevance of considering media production as a social process and thus reflections and simultaneous and articulated analysis of the media industry, the media texts and the audiences and reception processes, as well as training for the use of media as selfexpression tools, creativity and resistance. The investigation process was a qualitative one, characterized as a documentary analysis carried out based on the methodological framework of discursive textual analysis. The results indicate some aspects worthy of special attention in structuring media education policies and programs in teacher training, including the permanence of prospects of media education as protection and not as a preparation for autonomous, critical and creative access and use of media; the understanding of media as a social process detached from other processes of reproduction and transformation within our societies; and the need for further reflection and advances in achieving articulation between the uses of media in science education as sources of content, pedagogical tool and object of study in its analytical and creative dimensions.

Local hypoxia (i.e. intramuscular) resulting from resistance training (RT) contributes to ions H+ accumulation and decreased muscle pH (i.e. metabolic stress). It has been suggested that the accumulation of these metabolites promotes an increase in the motor units (MU) recruitment and consequent increase in cross-sectional area (CSA) and muscle strength. Nevertheless, it remain sunknown whether the level of local hypoxia can affect the magnitude of these adaptations. Objective: The objective of the study was to analyze and compare the effect of local hypoxia during low-intensity resistance training with blood flow restriction (LI-BFR: 3-4 x 20/20% of one repetition maximum [1-RM] / 60% total pressure of occlusion), high-intensity resistance training (HI-RT: 3-4 x 10/80% of 1RM) and high-intensity resistance training with blood flow restriction (HI-BFR: 3-4 x 10/80% 1-RM / 60% total occlusion pressure) on muscle activation, strength, mass and architecture in young individuals. Methods: Thirty young men were selected and each leg allocated to three experimental conditions through unilateral knee extension in randomized order and counterbalanced after ranking by strength level (1- RM) and vastus lateralis (VL) muscle CSA quartiles. The dynamic maximum force was measured by 1-RM test and CSA acquisition, muscle thickness (MT), pennation angle (PA) and VL fascicle length (FL) was performed through ultrasound images. The training program consisted of 10 weeks with a minimum interval of 72 hours between training sessions and the measurement of muscle activation by surface electromyography (EMG) and deoxyhemoglobin ([HHb]) and oxyhemoglobin ([HbO2]) concentrations through near-infrared espectroscopy (NIRS) of VL, performed during the training session with relative load obtained after the 1-RM, before (T1), after five (T2) and ten weeks (T3) training. Results: The training total volume (TV) was greater for HI-RT and HI-BFR compared to LI-BFR. There was no difference between the groups in regarding the increase of 1-RM, CSA, MT and AP. However, the FL showed higher increase for HI-BFR compared to HI-RT and LI-BFR. Regarding the magnitude of the EMG, the HI-BFR group showed higher values than HI-RT and LI-BFR. On the other hand, [HHb] were higher for HI-BFR and LI-BFR, however there was no difference between groups on the reduction of [HbO2].Conclusion: The level of local hypoxia does not influence the magnitude of the increase of muscle activation, strength, mass and architecture changes after resistance training. However, the addition of local hypoxia seems to have a greater contribution to the adjustments resulting from the low-intensity resistance training compared to high intensity.
