The discussion on monetary policies in the history of economic thought has shaped itself facing political and economic events throughout history. From the quantitative theory of money (QTM) and the Keynesian theory to the policies of inflation targeting and zero interest rates today. This recent interest in zero interest rate policy (ZIRP) or negative interest rate (NIRP) has attracted the attention of economists, academics and policy makers. The present work aims to evaluate and to identify if the reduction of economic growth imposes or not a technical limit for the formulation of policies of interest rates. In addition, it aims to incorporate population variables into the analysis to model possible demographic impacts on interest rates, as populations in most countries are showing lower or even negative population growth rates, shifting demographics of countries towards greater representation of the older population. The possible relationships between the variables will be tested through panel data models, where annual data of interest rates, economic growth, inflation rates and demographic growth/evolution for the period from 1960 to 2015 will be used for a set of countries which adopted zero and/or negative interest rates after the 2008 crisis. The conclusion is that the aging of the population seems to restrict the possible stimulus of monetary policy, generating lower interest rates over time.

The objective of this research is to analyze an intervention in a Sports Curriculum Activity of futsal as well as the application process in test to evaluate the game performance. The research method consisted of strategic action research developed at a state school in São Carlos, for which the researcher carried out an intervention of ten classes that included the application of the TSAP test at the beginning and at the end of this process. The test itself is an effective evaluation method for team sports worked in a teaching unit because it is able to collect data that serves to understand the level of collective and individual game. The training was carried out from the tactical demands of the game based on the pedagogy of team sports. With the application of the intervention we can report that there was on the part of the students a concern with the objectives of the game and questions during the activities and the TSAP helped to see at the end of the intervention the performance of the students.

The objective of this research is to analyze the economic impacts of the reorientation of the national transport flow towards the ports of the North, as it is currently concentrated in the ports located in the South and Southeast of the country. Through an analysis of the freight prices and export volume of the soybean from the Central West Region to the ports of the North and South and Southeast of Brazil, it was possible to establish efficiency gains, which supported the shocks applied through a computable general equilibrium model, to identify the direct and indirect effects of this possible reorientation trough North. The results indicated that there are gains caused by a possible redirection of the transport flow, however, as a rule, they concentrate income and benefit mostly the Central West Region. Thus, competitive gains obtained by this region are in detriment of the other regions of the country. In addition, the economic impacts of the shocks did not present a high intensity, since the "transport" input, where the efficiency shock was applied, is only one among the various inputs used in soybean production. The alternative of increasing the transport flow trough the North has been shown effective, but not enough to fix the logistical deficit that challenges the Brazilian agribusiness performance. Therefore it is necessary to combine this reorientation with other measures that may bring greater dynamism to the country.

The present work describes a case study with the objective of investigating the impact of intrafamily violence on the academic performance of children in the target group of special education considering the conditions of children with disabilities exposed to this context of violence. The participants were a child with disabilities in school, his mother and the teacher of the regular classroom of the school he attended. The results showed the low quality of family relationships and the impact on the child's academic life. It was concluded that the low quality of interactions in the family environment can be aggravating for the learning of the target audience of special education.

Brazil went through a political and economic crisis period from 2013 to 2016. The electoral results, in 2014 interfered in the local stock market risk. Data from BM&FBOVESPA suggested an increase in the local stock market volatility. Similarly, loss in the most of the companies` market value. Recession and crisis marked the following years. However, loses in financial and consumer`s sectors seemed to be lower. In this way, we asked if also the systemic risk would have grown, if the central companies and sectors would have changed and what would be the minimum variance and systemic risk portfolios. A dynamical Minimum Spanning Trees (MST) analyzed the systemic risk. I built 48 mothly MST´s from October 2012 utill September 2016 and analyzed the first four moments of the distance correlation matrix. I proposed two MST`s to verify the optimal portfolios and changes in the central companies and sectors: one for the two years before the re-election of Dilma Roussef and another for the two years after. I compared the central vertices and the number of clusters by hierarchical clustering. By observing the MST length`s shrinking and the increases in the correlation level, I discovered that the systemic risk grew through the following six months after the electoral results. Changes in the inclination of the distance correlation`s asymmetry and kurtosis suggested expectation and uncertainty changes. The hierarchical clustering revealed that the central stocks before the reelection were BBDC4- Bradesco Bank and EVEN3-EVEN Construction Company. After that, BBCD4 and ITSA4 – Itau Bank remained as the most central stocks. Construction sector left to be an important sector and stood by ITSA4 periphery. I suggested 8 clusters for each period as the available number for portfolio diversification for systemic risk reduction. The 20 lowest closeness centralities indicated the minimum variance portfolios for both periods.

Public initiatives in the field of technological education in Brazil aim to minimize the problems related to digital exclusion through the mass distribution of computers to schools and the construction of collective internet access centers. Such initiatives, aimed at digital inclusion, are often advertised as synonymous with social inclusion policies. In order to problematize this reality, the present work investigated, in the light of the Critical Theory, the contradictions observed in the process of implementation of the program conceived by the State Department of Education of São Paulo called Acessa Escola, considered one of the most comprehensive policies of digital inclusion from the country. The analysis has shown that the numerous obstacles to ICT use in schools, such as low connectivity, the constant need for equipment maintenance and the lack of training courses for teachers, lead to the underutilization of the technological apparatus, contributing to disseminate the semiformation in the teaching units.

In the quebrada of Heliópolis, anually on the Sunday before Christmas, the famous soccer team Flor de São João Clímaco performs in its Villa Arapuá’s field the party of the Black Versus White’s Game, a festival that mobilizes residents of Heliopolis and surroundings. The event took place forty-four years ago, and, since the first editions, it updates two premises that knowledge teaches. Firstly, to celebrate the friendship. Secondly, it is sought to establish whether the best is the black or the white ones. Not excluding the differences, it’s in the first premise that I prefer to conduct the mind to reflect with the quebrada. Thereby, when we take the opportunity to celebrate the friendship at the Black Versus White, beyond engaging in a celebration, we experience the situation of producing connections and differences between we, who are from the quebrada. With these teachings, the Black Versus White suits me as a metaphor to express the writing of this dissertation. In each pen’s movement, I seek to establish connections and contrasts between my quebrada and Anthropology in a single narrative regime. A writing that places the epistemological problem of the knowledge’s possibilities when the thinker has the opportunity to join the university through affirmative actions and chooses to study Anthropology to master the quebrada’s knowledge that projected him to the world. Humbly, this dissertation is part of my struggle, and, because of the method that struggles for the right, I could only present what follows in the shape of this mixtape. In the A-side, I present a more conceptual stuff, and, in the B-Side, the tracks aims a certain type of narrative about my quebrada, in which I intend to develop with the master’s degree in social anthropology.

Brazil, that already was the largest producer of natural rubber in the world, faces a deficit in its production, what has resulted in the necessity to research of clonal varieties of rubber trees with high quality and productivity adapted to different areas. In view of this scenario, this study sought to evaluate the chemical composition and as properties from natural rubber of the new clones the effect of the coagulation method on the latex clones RRIM 600 and RRIMM 937 and the influence of the non-rubber constituents soluble in acetone in properties of plasticity Wallace (P0) and plasticity retention index (PRI). The samples were evaluated by physical-chemical, thermal and rheological tests of: DRC, TSC, particle size distribution and Zeta potential, FTIR, NMR, determination of macro and micronutrients by ICP-OES, acetone extract content, ash, nitrogen content, Wallace plasticity, plasticity retention index, Mooney viscosity, thermogravimetry, DSC and rheological behavior. From the obtained results a variance analysis with repeated measures and tests of multiple comparisons was made to evaluate the behavior of the clones in relation to the plots and the collections. Pearson's correlation was used to evaluate the correlations of the variables. The results showed that there were more variations between the clones and the collections in the composition than in the properties. The rubber produced by the new clones presented good performance considering the standards established by the norms, except the clone RRIM 711 that presented the greatest variations in properties and lower values than the others. All clones showed uniformity in the thermal evaluation, and in the inert atmosphere the decomposition occurred in a single stage with a temperature of beginning of degradation varying between 275–280 °C and in oxidative atmosphere occurred in three stages with the temperature of beginning of degradation varying between 210–220 °C. The NMR and FTIR spectra have shown that the natural rubber structure for all the clones studied has mostly the cis-1,4-polyisoprene form. The coagulation method altered the properties of the natural rubber and the extraction of the non-rubber constituents soluble in acetone directly affected the PRI values.

Given the difficulties of the educational system, new strategies seeking learning and teaching proposals have been suggested. Cinema stands as a possibility, because it is possible to convey information and raise the interest of the audience in a very effective way through the movies language. The outreach activity – ACIEPE: Cinema with Science (2016) was proposed to connect cinema and science through discussion of scientific issues informally addressed in the movies. Surveys were answered by the end of the exhibitions. The perceptions of the ACIEPE’s attendees on the movie “Creation” have been analyzed through a qualitative methodological approach. Common elements students speeches allowed the setting of categories. Results have established six categories based on the main aspects raised by the survey’s participants. Among them, the most relevant aspect (corresponding to 53% of responses) was related to the reason why people enjoyed the movie and referred to the humanized vision of the scientist depicted in the art piece. This contrasts with the stereotyped way scientists are usually portrayed by the media. The experience of watching a movie that shows a scientific personality, Charles Darwin, through a different approach has allowed everyone to be closer to a more natural and human view of the scientist. This highlights the cinema as an interesting didactics tool, because this art would assist in the teaching-learning process through its potential to deconstruction and reconstruction opinion.

Several studies take place in order to reduce and even extinguish formaldehyde use in its various applications. This is due to its classification as a carcinogen according to the International Agency for Research on Cancer (IARC). Most of the formaldehyde production is destined to obtain amino resins. After the synthesis of these resins formaldehyde being fully reacted is no longer found free and therefore presents no carcinogenicity risk. However, these amine resins when used as a binder in wood composites, can release formaldehyde. MDP (medium density particleboard) panels were produced on laboratory scale using as binder urea formaldehyde resin and the mixture of urea formaldehyde resin with MDI (diphenylmethane 4,4 'diisocyanate). The MDI partially replaced the formaldehyde urea resin at concentrations of 10%, 20% and 30% in order to evaluate in these mixtures the influence on perpendicular tensile strength, also known as internal adhesion, in determining swelling and water absorption after immersion For 2 hours and 24 hours, formaldehyde emission and flexural strength. The resin blend was effective in reducing the emission of formaldehyde and an increase in the mechanical properties was possible. Among the conditions evaluated, condition 3, with 20% of methyl 4,4 'diisocyanate (MDI) and 80% of formaldehyde urea, presented the most satisfactory results in relation to cost-benefit. In condition 3, the formaldehyde emission was reduced by 75% and the results of the mechanical properties evaluated were satisfactory. In all analyzes, an increase was observed in relation to the panels produced with urea formaldehyde resin.

Ultrasound imaging is one of the most used modalities in medicine since it is low cost and has no ionizing radiation. However, ultrasound images are corrupted by a signal-dependent noise, known as speckle, causing a granular pattern that makes it difficult for visual or automatic image interpretation. Many filters have been proposed in the literature for speckle removal, and more recently, a great deal of attention has been focused on non-local techniques, as the non-local means filter (NLM) and the block-matching collaborative filtering (BM3D). The central idea of these recent methods is a measure of similarity between patches, originally proposed as the Euclidean distance for filtering additive white Gaussian noise. In this work, an approach is proposed for reducing speckle noise based on the non-local techniques and using the support of the information theory. Stochastic distances are derived for Rayleigh, Nakagami and Fisher-Tippett distributions, and used as similarity measures in NLM and BM3D filters. Two methods are applied to generate these stochastic distances. The first method is based on symmetrized statistical divergences and the second one related to the geodesic distances in probabilistic spaces. Although similar approaches already exist to despeckle synthetic aperture radar (SAR) images, here they are adapted and extended, in an unprecedented way, to handle the specificities of the ultrasound images.

Some studies have shown that posterior capsule tightness may be related to shoulder dysfunctions and alterations in range of motion. However, there is no consensus in literature about how to specifically assess posterior capsule tightness, considering that bony adaptions, as humeral retroversion, may influence the clinical measurements suggested in previous studies. Furthermore, few studies have evaluated the effect of interventions on the posterior capsule tightness. In addition, the low quality of the studies limits the clinical decision-making. The aims of this thesis were: 1) to assess scapular and humeral kinematics, shoulder range of motion and external rotators strength, pressure pain threshold, pain and function in individuals with posterior capsule tightness with and without shoulder pain; 2) to compare the effects of a specific and a non-specific intervention to posterior capsule tightness and pain in individuals with capsule tightness and shoulder pain on the same outcomes presented in aim 1; 3) to determine how the posterior capsule tightness and humeral retroversion interact and influence measurements used to measure shoulder range of motion in the clinical practice. The posterior capsule tightness was quantified by the Low Flexion test. The humeral retroversion was quantified using the bicipital forearm angle. The electromagnetic system was used to measure kinematics. Digital inclinometer, dynamometer and goniometer were used to assess range of motion, muscle strength and pressure pain threshold, respectively. The Shoulder Pain and Disabilities Index (SPADI) assessed shoulder pain and function. In general, the results showed that individuals with shoulder pain presented changes in scapular and humeral kinematics and in shoulder range of motion, which were not intensified with posterior capsule tightness. However, the capsule tightness associated to shoulder pain contributed to worse pain and function of the shoulder, and decreased pressure pain threshold, which suggest increased pain sensitivity. After 4 weeks of intervention, only the specific one decreased the posterior capsule tightness. Both protocols decreased the humeral translations, shoulder pain and increased shoulder range of motion and pressure pain threshold. The posterior capsule tightness and humeral retroversion influenced the clinical measurements, but the two combined condition showed greater shoulder range of motion deficit. Thus, it is believed that individuals with the same musculoskeletal dysfunction, as shoulder pain, may respond differently to pain and develop individual adaptations to avoid pain and to preserve function. Further investigation of the clinical measurements used in the present study is needed in individuals with shoulder dysfunction.

In this research, the concept of applied competence (AC) of Almeida Filho, developed in the context of the Almeidian Model, is analyzed. This model covers two specific frameworks of the Language Teaching and Language Learning Field (LT/LL): The Foreign Language Teaching Overall Operation (FLTO) and the Overall Operation of Professional Education (OPE). The first deals with the phenomena and the theorization of the processes related to language teaching and learning. The second deals with the processes of teacher education. This investigation is aligned with a reflexive education perspective, endorsed by the OPE. The Almeidian Model, therefore, is taken as the main theoretical orientation of this study, but it also resorts to other theoretical support as those presented by Moscovici (2007), Jung (2000), and Bandeira (2015) among other authors. The focus of this research relies on the Applied Competence (AC) developmental aspects. In order to achieve the research results, phenomena which arise as relevant factors in the clarification of the elements in the language teaching and in the dialectical synthesis of the components in the process are examined. This applied, interpretative, and ethnographical research had as tools in the data collection: class observation and recording in video and audio, semi-structured questionnaires, field notes, interviews and informal conversations with the participants of the research. The main leading question of this study inquires about how the participants of the research develop their AC. A subsidiary question aims at identifying what necessary elements are manifested in the applied competence development. The main purpose consists in understanding the aspects of AC and a secondary objective aims at identifying the elements needed for the development of the AC. The research has as its scenery a public language center. The participants of the research are teachers who work in that language center. They were divided into two groups. The first group, which was constituted of all the participants in the research, provided the data on the school context and collective or social aspects within the range of the space where the research took place. The data provided by the second group, formed by three members of the first group, are directly related to the questions addressed and the research objectives. The results demonstrate that the AC, inserted in a system of competences, is a competence of formality, that is, it comprehends two categories: one of explicitness and the other of synthesis. The first is developed stem from the process of making the elements of OPE explicit, including the teaching approach, language teaching and learning theories, attitudes facing the elements and subjects in the professional field and the professional activity. The second is constructed from the dialectical relationship of the elements of the explicitness category. The synthetics category gives origin to the components of the AC. The data analysis also indicates that the elements involved in the process of explicitness do not form the AC components. It occurs through the process of synthesis of the elements previously made explicit. This research contributes, among other factors, to the elaboration and implementation of policies and programs of language teachers continued education.

Xylitol is a five-carbon polyalcohol presented in many fruits and vegetables, as well as yeasts, lichens and mushrooms. It is a white crystalline powder and odorless sweetener. Compared to sucrose, it has similar sweetness and reduced caloric value, besides being independent of insulin for its metabolizing, so it is tolerated by diabetics. Xylitol can be obtained by solid-liquid extraction, chemical reduction of xylose and biotechnological conversion of xylose. The low concentration of naturally occurring xylitol (less than 0.9 g/100 g) makes solid-liquid extraction process economically impracticable. The catalytic reduction of xylose offers high yields, but suffers disadvantages mainly due to extensive intermediate purification steps and huge energy requirements, which makes the overall process very expensive. The disadvantages in the conventional method of xylitol production and the market growth over the last years have motivated researches looking for alternative ways of obtaining this product. One of the most attractive processes is microbiological route, which uses microorganisms (yeasts, bacteria and filamentous fungi) with capacity to assimilate and ferment xylose. Xylose is obtained by treating methods of lignocellulosic materials, such as hydrolysis. Sugarcane bagasse is a highly lignocellulosic residue produced in Brazil as a result of the intense sugar-alcoholic activity and it can be used in xylitol production. Thus, this study aimed to simulate and evaluate batch production of xylitol by fermentation using Scilab, a free software for numerical computation. This was possible by defining kinetics for substrate consumption (xylose), cell growth (yeast) and product accumulation (xylitol) and by resolution of the ordinary differential equations resulting system. The kinetic model used was proposed by Mohamad et al. (2016) in the study of xylitol production by fermentation of pure xylose by Candida tropicalis and was suitable to this process. The simulation of data obtained by Arruda (2011) in the fermentation of detoxified hemicellulosic hydrolysate of sugarcane bagasse by Candida guilliermondii resulted in many divergences between experimental values and those predicted by the mathematical model. The kinetic model was suitable only at the beginning of the fermentation process, but it is promising in the prediction of xylitol formation from hemicellulosic hydrolysate of sugarcane bagasse. Studies indicate that this process is a satisfactory alternative for xylitol obtaining, but still needs a better understanding.

Various environmental problems have been lived during the last decades, mainly caused by socioeconomic predominant models, confirming the needed of accomplished with Environmental Education, principally regarding school ambit, where the Environmental Education development must be responsibility of all subjects, that the highlight is Chemistry. Considering this problematic, this master degree work looked for didactic strategies to articulate the Environmental Education in the Basic Education Chemistry Classes, using water as the subject generator and the National Curricular Guidelines for Environmental Education as guiding, the strategies proposed were structured by Didactics Sequences . Three Didactics Sequences were building by study of National Curricular Guidelines for Environmental Education , São Paulo Chemistry Curriculum and the previous questionaries’ analysis applied in students participants of search. The Didactics Sequences elaborated were applied in the classroom and data collected by questionnaires, class reports, students’ activities, observation and audiovisual records. The data analyses show that the developed activities contributed for the student’s environment perception evolution from Naturalist for Globalizes, as well as insert social elements in contents which relate with Environment Education, however, the Didactics Sequences did not get successful to engage students regarding environment question, being one of the points to be improved on them. In relation of Chemistry Teaching, the classes dynamics allow diagnostic compression problems and students lacks, which in the traditional style of classes only would be revealed by writing evaluation, activities of final periods. The socioenvironmental contextualization allows to close the contents of the student realities and motivate their learning. The activities proportionated the development of abilities to realize searching and argumentation building, the responsibility and autonomy stimulation of students.

The research aimed to create a Scientific and Technological Knowledge Management Model for organizations of Profession and Technological Education, departing from the implementation of the institutional repository Dspace in São Paulo Federal Institute of Education, Science, and Technology (IFSP). Methodology comprehended an exploratory-descriptive case study composed of four methods: 1) Literary review on knowledge management (KM) in organizations of professional and technological education; 2) Empiric research with the use of a data collection technique - questionnaire; 3) Creation of the proposed model; 4) Implementation of the institutional repository. The results are presented accordingly to the objectives of the study: 1) comprehension of the state of the knowledge management art in the professional and technological education context; 2) elaboration of a knowledge management model for organizations of professional and technological education. For the model composition it was used the community of practice technique, which presented itself opportune; 3) Implementation in initial stage of Dspace in São Paulo Federal Institute of Education, Science, and Technology; 4) structuration of storage and use of information policies in the institutional repository for the tool implementation. For considerations, the study points out that: a) the proposed model can offer a parameter for congener organizations; b) the proposed model, yet conceptual, will be able to be susceptible to replication; c) the inclusion of the administrative documentation in the institutional repository presents itself as relevant element in the organizational process; d) The institutional repository will be able to act as management tool in institutional decision-making; e) it is suggested greater exploration of the use of the community of practice technique in the academic-scientific context. We conclude that the proposed conceptual model presents the possibilities of implantation of the KM in IFSP and the applied questionnaires made possible to understand the panorama in KM of IFSP. We highlight the importance of the community of practice for the socialization and externalization of the organizational knowledge.

To address the diversity of users and the different interaction requirements, the user interfaces could be more flexible, being adapted according to each user profile. Currently, some web interfaces are already flexible, but this flexibility is usually made from explicitly made adjustments by the user in each website. The flexibility achieved by the interfaces of the current websites is not enough when the diversity of users and different interaction needs are considered. In addition, to adapt a web system, currently the user has to configure each system individually and not all users are aware of the different possibilities of presentation and configuration of the websites. Since the interfaces must be flexible to meet the different needs and diversity of users, this work aims to provide users with the possibility to adapt the websites according to their needs and preferences. To achieve this goal, an approach was formalized where the user defines his interaction profile, based on rules, guidelines and good design recommendations, and later this interaction profile is used to adapt the interfaces. In addition, the UIFlex tool was developed, where the user defines their interaction profile and, from this profile, the tool flexibilizes the interfaces of the websites that users navigate according to the interaction profile defined by the user. Finally, two evaluations were carried out in different scenarios: one face-to-face and the other online. These evaluations were carried out with the purpose of verifying the viability of the UIFlex tool and whether it meets the diversity of users. In both scenarios, users accessed certain websites with and without the UIFlex tool and subsequently answered questionnaires related to user satisfaction, website behavior and interaction efficiency. The results of the questionnaires answered indicated that the UIFlex tool brings benefits during the interaction of the users with the websites, mainly related to the efficiency, due to the adaptation made in the websites by the tool, without the need to configure each website individually. With the studies carried out and with the analysis of the answers of the questionnaires it is concluded that the UIFlex tool contributed positively to the users adapting the interfaces of the websites according to their preferences and/or needs.

This research has as social practice the Popular Extension in Environmental Education, developed by an extension group formed by seven people, six students of the Environmental Engineering course, University of Uberaba and the researcher, professor of the same course. The bibliographic review reveals the existence of a close relationship between critical environmental education, popular extension and popular education, since its fundamental bases are structured in the protagonism of the subjects, in the conquest of their autonomy, freedom and emancipation, besides recognizing that the process of domination, oppression and colonization of knowledge, which is triggered by social / environmental injustice. The theoretical reference of the research is linked to that of Popular Education, Popular Extension and Environmental Education, specifically Critical Environmental Education. It has as general objective to know the educational processes that propitiate the formation of environmental engineers as environmental educators, based on the social practice previously mentioned. We opted for the qualitative research modality, which is understood as an investigation that has as central concern the examination of the data in depth, taking into account the historical and / or social perspective of the moment in which the analysis is performed. We also understand that this research is descriptive, because it exposes the characteristics of a certain population or a certain phenomenon, and it is worth, as far as the means to obtain data, of field research and bibliographical research. The observations were recorded in field diaries. To analyze the data, we are using the content analysis, in which, in the pre-analysis, the analyzed documents were the field diaries, without losing sight of the problem question and the research objectives. The transformation of the data into units of registers occurred from the interpretive convergence of the paragraphs of the field diaries. Starting from the convergence between these units, the initial, intermediate and final categories were elaborated, the latter being object of analysis and final interpretation in the thesis, which is structured as follows: Initially, in the introduction, I present my life trajectory and in it I include my academic trajectory, arriving at the doctoral research, to, from the bibliographical review, present the problematic, the problem question and the objectives of this research. The research was carried out together with a group of environmental engineering students from Uberaba University, in the city of Uberaba, who are popular extension with a group of residents of Vila Esperança II and Jardim Itália, a working community. The first chapter brings the methodological approach of the research. The second chapter presents a discussion about education and culture, education as culture and education in the context of social practices, which has popular education as a way of possibilities for overcoming existing relations of oppression. The third chapter presents a historical-critical review about the context of the Brazilian university, from its origin to the present day, looking more especially for the practice of university extension. In addition, it takes popular extension as a social practice, in order that through this look, understand it as a source of production of conversational knowledge. The fourth chapter presents a discussion about the critical concept of what we mean by sustainable development, going through an analysis of the environmental dimension of education, and then discussing Brazilian environmental education, based on the study of macro trends in the country, with emphasis on macro-education Critical Environmental Education and one of its four currents, Popular Environmental Education. The fifth and final chapter presents the analyzes and results of the research, especially around the educational processes that permeated the training of extension students in the work community.

Due to existence in abundance in Brazil, low energy consumption, less fuel quantity in its production process, not being flammable and recycling possibility, gypsum is extremely viable in civil construction. Among its applications, it is used as acoustic and thermal insulation due to the natural porosity of this material. One way to improve these applications is by adding pores. However, with pores addition in this material, its mechanical resistance decays significantly, necessitating the addition of micro silica. In this way, the study of gypsum foams for acoustic and thermal insulation together with micro silica percentages, to increase mechanical resistance, are presented as important and original from a technical and scientific point of view. The present study covered two important steps: preliminary experimental planning and definitive experimental planning. The preliminary experimental planning was important to define the base additive percentages, as well as the best water/gypsum ratio to be used and the ideal cure time. In the definitive experimental planning, the micro silica percentages were varied and statistical analysis (regression models) was performed, thus defining the best percentage of micro silica in order to reach the best result of each property. The gypsum foams results were satisfactory, reaching 87.88% porosity and excellent acoustic and thermal absorption. The micro silica also showed its effectiveness, improving 200% the uniaxial compression resistance and maintaining the effectiveness in acoustic absorption and thermal conductivity. The regression models used had representativity, in other words, with micro silica percentage, it was possible to estimate gypsum foam properties, allowing to extrapolate micro silica percentage to values not used in this research.

The project chased the characterization of the new institutional formats in the diffusion of the logic of venture capital in the public banks of Brazil, as public banks are adopting tools linked to the venture capital industry with the justification of gaining greater financial flexibility, otherwise the agents would use these structures legitimized in the financial market with the purpose of seeking greater innovation leveraging the development of the economy. The collection of data was done through financial reports as well as normative reports. In the analysis the adopted structures and the interactions with the other agents of the financial space were identified with the proposal of an analysis framework taking into account the economic sociology and the theory of the organizations.
