Cross-platform Development Tools are a technology that emerged to meetthe demand of development teams that operate simultaneously with more than onemobile platform. This technology mainly benefits small and medium-sized teamsthat did not have the capacity to maintain two or more different code bases for thesame project. The use of these tools has become more and more popular accord-ing to the evolution of the technology employed capable of producing applicationsincreasingly closer to one developed natively. As the popularity of cross-platformtools grows, so does the need for a concise, flexible and long-lasting way of definingtheir advantages and disadvantages over other tools. So the objective of this work isto find out through mixed methods of data gathering such as questionnaires, inter-views and practical studies what really matters to the developers, thus contributingto the evolution of the state of the art by providing a set of criteria that can beused to make comparisons. And enhancing the state of the art with a comparisonbetween the development tools most used today. Results shows that the most im-portant decision factors are Responsivity, Long Term Viability and Maintainability.It was also indentified that the most complete tools are React Native, Flutter andXamarin.

Science has consolidated itself in the social structure as much as technology, both differing in the relationship established with society. The scientist has as a commitment to science the need for scientific communication and its social function is scientific dissemination. Taking into account the proximity between the STS field and the scientific communication and dissemination processes, this research aims to investigate the scientific publication and dissemination practices of leaders of research groups in the STS field, registered with CNPq. This is an exploratory and descriptive research that aims to verify whether researchers working in the STS Field comply with the science dissemination assumptions recommended by the Field itself. With regard to the characterization of the STS groups and the scientific production of the leaders, the area of Education has great prominence in STS studies, proposing, predominantly, to study the ways in which the STS field impacts education and the way in which Education can contribute to advances in the STS field, such as deepening and discussing ways of dealing with the issue of scientific illiteracy, which is among the themes of greatest study by leaders. Bibliometric and altmetric indicators pointed out that bibliographic production and more traditional channels, such as congresses and journals, are the most used by leaders for scientific communication. In the altmetric analysis of the articles published by the leaders, Mendeley, the academic social network, received the most attention online. Of the 87 leaders of STS research groups, 17 are authors of articles that received attention online. It is concluded that although leaders denote having a consolidated scientific communication, according to the methods used in this research, they show that there is still a way to go for effective engagement in scientific dissemination through social networks, which in a way denotes that the premises advocated by the STS Field itself of the greatest proximity between researchers and society should be encouraged.

The AA 3104 aluminum is widely used as packaging for food storage, as it is a versatile alloy with easy mechanical conformation, however, it causes high wear to the cutting knife due to friction during the packaging operation. The objective of this study was to evaluate the wear resistance of steel containing 0.2% C, commonly applied to tools to perform forming and cutting operations on AA 3104 aluminum alloy, subjecting this steel to plasma ion nitriding and deposition treatments amorphous carbon film (a-C:H), to study the wear behavior of the material with and without surface treatment. The a-C:H films were deposited by PECVD on 1020 steel samples after cleaning the substrate by plasma ablation, with atmospheres of 80 and 90% CH4, with voltage varying between 500 and 600V. For the adhesion of a-C:H film to the metallic substrate, a silicon interface was deposited using hexamethyldisiloxane as a precursor, whose deposition was carried out with a gas flow of 30 sccm, containing 70% HMDSO and 30% argon. The plasma nitriding treatments were carried out with an atmosphere containing 80% N2 and 20% H2 with temperatures at 400, 500 and 600 °C. Also, plasma nitriding treatment was carried out where the temperature was maintained at 550 °C and the gas proportions were varied by 60% N2 and 40% H2, 80% N2 and 20% H2 and 92% N2 and 8% H2. All samples were subjected to the micro-wear test by fixed ball and the prototypes of the treated tools were tested using a wear machine specially built to simulate the friction between 1020 steel and AA 3104 aluminum. The final wear analysis was done through the optical moiré technique by phase-shifting that allowed to analyze both qualitatively and quantitatively the volume of body wear with and without treatment. Among the nitrided samples, those that were produced with higher nitrogen rates showed greater hardness due to the formation of the Fe2-3N phase, reaching values of 585 HV, however the samples with a low nitrogen atmosphere obtained Fe4N phase where they showed to be more resistant to frictional stresses due to its greater ductility in relation to the Fe2-3N phase, ensuring 60% less wear on untreated material. The a-C:H film produced with an atmosphere containing 80% CH4 showed a lower roughness among all samples (44.3 nm), leading to a lower wear volume (1.015x10-4 mm3). The a-C:H films gave steel 1020 results superior to nitriding, with a 95% reduction in wear volume. It was observed that all treated samples obtained an increase in wear resistance, when compared to the base material, thus making it possible to reduce the wear of the 1020 steel tools used for cutting aluminum AA 3104 and, subsequently, increasing its useful life.

In this work, a new class of discrete models for the analysis of zero-modified count data has been introduced. The proposed class is composed of hurdle versions of the Poisson-Lindley, Poisson-Shanker, and Poisson-Sujatha baseline distributions, which are uniparametric Poisson mixtures that can accommodate different levels of overdispersion. Unlike the traditional formulation of zero-modified distributions, the primary assumption under hurdle models is that the positive observations are entirely represented by zero-truncated distributions. In the sense of extending the applicability of the theoretical models, it has also been developed a fixed-effects regression framework, in which the probability of zero-valued observations being generated as well as the average number of positive observations per individual could be modeled in the presence of covariates. Besides, an even more flexible structure allowing the inclusion of both fixed and random-effects in the linear predictors of the hurdle models has also been developed. In the derived mixed-effects structure, it has been considered the use of scalar random-effects to quantify the within-subjects heterogeneity arising from clustering or repeated measurements. In this work, all inferential procedures were conducted under a fully Bayesian perspective. Different prior distributions have been considered (e.g., Jeffreys' and g-prior), and the task of generating pseudo-random values from a posterior distribution without closed-form has been performed by one out of the three following algorithms (depending on the structure of each model): Rejection Sampling, Random-walk Metropolis, and Adaptive Metropolis. Intensive Monte Carlo simulation studies were performed in order to evaluate the performance of the adopted Bayesian methodologies. The usefulness of the proposed zero-modified models was illustrated by using several real datasets presenting different structures and sources of variation. Beyond parameter estimation, it has been performed sensitivity analyses to identify influent points, and, in order to evaluate the fitted models, it has been computed the Bayesian p-values, the randomized quantile residuals, among other measures. Finally, when compared with well-established distributions for the analysis of count data, the competitiveness of the proposed models has been proved in all provided examples.

Compared with traditional separation methods, polymeric membranes have low operation cost, fast separation rate and versatility. One interesting way of changing membrane properties is mixing additives into the polymeric matrix. Polyelectrolytes complexes (PECs) (polyelectrolytes combined via electrostatic interaction) are a good material for that due theirs hydrophilicity, tunable surface charge, stable structures and insolubility in common solvents. Based in this context, inversion phase membranes containing PECs were obtained through three different methodologies: in situ, post crosslink and simultaneously crosslink. The chosen polyelectrolytes were 4-fluorophenyl sulfone terminated poly(diallylpiperidinium hexafluorphosphate) (PDApipPF6) and sulfonated poly(ethylene terephthalate) (SPET). The polymeric matrix used was polyether sulfone, known for its good mechanical strength and high temperature stability. Analysis by fourier transform infrared spectroscopy confirmed the presence of SPET in the PEC membranes, while the presence of PDApipPF6 was confirmed by positives values of zeta potential. Scanning electron microscopy images of the cross-section of the membranes were similar and showed asymmetric structure consisting of a dense skin and porous sub-layer. The increase of water vapor permeability and the decrease of water contact angle of the PEC membranes indicated that the presence of the complexes alters the membranes’ hydrophilic profile. Differences in the curves of the thermogravimetric analysis showed that depending on how the PECs are obtained, the interaction between the PELs changes, which produces membranes with different thermal behaviors. The results of filtration and adsorption of remazol red also varied with the methodology.

The correct inference of growth and forest production are important factors for decision making in planning, with different models based on regression statistics. These models are used to determine the technical and economic age of the cut, to generate production tables for the stands and growth curves. Due to its importance and the search for more accurate estimates, the development of more complex models has been applied in the forestry sector, among which we can mention the mixed modeling and the use of quantile regression. The aim of this work was to evaluate the use of a new technique using linear mixed models with quantile regression in the projection of growth and production in an eucalyptus stand and also to compare the volumetric estimates with those obtained by the traditional Clutter model and mixed modelling. The data came from a clonal Eucalytpus spp. stand, located in the interior of São Paulo state, aged between 24 and 64 months. Adjustments to the equations of the Clutter model, as well as the mixed-effect models and the linear mixed-effect models with quantile regression, as well as the linear mixed model with quantile regression and mixed-effect models were performed using the statistical software R. To check the accuracy of the methods, the last measurement was selected as a reference and, based on this, classes of projection periods were created at 12-month intervals, which are: (6,18], (18,30] and (30,42] months. The evaluation was carried out through the residual plot, as well as through the square root of the average error (RMSE %). It was found that the mixed model and linear mixed model with quantile regression obtained a lower RMSE of 3.94% and 4.20%, respectively, for (6,18] month class. For the classes (18.30] and (30.42) months, the traditional Clutter model that presented lower values of RMSE, being 4.28% and 4.75%, respectively. After the analyzes were carried out, it was defined that for the class of (6,18) months the use of the linear mixed model with quantile regression due to the RMSE is indicated and also present the best dispersion of the residues. For the classes (18,30] months, despite the traditional Clutter model presenting the lowest RMSE, after analyzing the dispersion of the residues it was found that the use of the mixed model is the most suitable due to better dispersion, and for the class of ( 30,42] months, the traditional model of Clutter is the most suitable.

Sodium-based materials are promising candidates for manufacturing stationary storage devices such as batteries due to their low cost and the Na high redox potential. However, the corrosion, flammability, and the degradation of cell components in sodium-ion batteries caused by the high operating temperatures may be listed as disadvantages of these devices. A possible solution to these problems is to optimize the ionic conductivity of the solid electrolyte. In this work, two methods were adopted to improve the ionic conductivity of NASICON (Na-Super Ionic Conductor) solid electrolytes. The first one focused on the substitution Si4+/P5+ in the unprecedented Na1+yTi2SiyP3-yO12 (NTSP) and Na2+yAlTiSiyP3-yO12 (NATSP) series, which allows the introduction of extra Na+ ions. In the second method, Na2AlTi(PO4)3 (NATP) and Na1.8Al0.8Ge1.2(PO4)3 (NAGP) glass-ceramics with different grain sizes were obtained to establish a correlation between microstructure and ionic conductivity. For the NTSP glass-ceramics, it was observed that the inclusion of Si4+ ions in the NASICON structure promoted an increase of up to four orders of magnitude in the total conductivity. The formation of a highly conductive phase was also seen in the compositions with a high content of silicon. In the NATSP series, there was no evidence of a Si4+/ P5+ substitution since the expansion of the unit cell was not observed. This behavior was attributed to the high tendency of precursor glasses towards phase separation. Regarding the NATP and NAGP glass-ceramics, materials with average grain size from the order of nanometers to micrometers were obtained. Therefore, it was demonstrated that the glass-ceramic method is suitable to obtain materials with controlled microstructure. The microstructural variation caused an increase of up to two times in total ionic conductivity. Thus, it was concluded that aliovalent substitutions promote greater increases in ionic conductivity of NASICON materials than those obtained by changes in the grain size.

This research aims to understand how the School Architecture theme, its object of study, has been considered within the History of Education area. The general objective of the research is to perceive within the highlighted time frame, the importance of the School Architecture theme within the studies of the History of Education field and how the theme relates the school physical spaces with the training of students and their learning. The specific objectives of this study seek to understand the contributions of research in the field of History of Education on the theme School Architecture, analyzing the methodologies used; periods of higher and lower academic production; which dimensions of the theme have been privileged and which conclusions it has established. The work methodology addressed in this study will be bibliographic research, with a qualitative approach. The research was carried out, initially, with the survey of academic works whose object of study privileged the theme School Architecture. Afterwards, studies were selected that intersected the theme with the Learning research category. The analysis of the works selected in the bibliographic research carried out in the research showed the historical and political character as a strong influence for the evolution of School Architecture and for the definition and determination of ideas and pedagogical trends. The research found demonstrated the educational factor that the materiality traits imprinted in the school environment. In addition to the teaching program, School Architecture determined a code of symbology, which surrounded behaviors and privileged others. The building, as a prominent place in the urban scene, was placed as a tool of power and segregation in the construction of the education systems, being of access and domain for few social strata and perpetuating itself in the collective memory as an intellectual and affective reference.

The aim of the research is to understand the conservative thinking of Francisco Campos and his reflections in Brazilian politics, especially during the Estado Novo, in the measure that he was the idealizer, based on the ideological construction of the National State. The research is justified by being an intellectual sometimes forgotten, but who played a prominent role in the national politics of his time, because camper thinking was based on integralist ideas and the European authoritarian and totalitarian movements of the early nineteenth century, and which were consolidated in Italian fascism, german nazism and bolshevik totalitarianism. The study is also relevant because Francisco Campos is characterized as anti-liberal and critical of party democracy, since in his perspective, this political model did not meet the new demands of the masses. In order to understand the camper thought, then, an investigation was needed in the period 1891-1968, passing through the brazilian integralist movement, led by Plínio Salgado, who contributed to the construction of Francisco Campos' conservative thinking due to the fascist influence. In addition, in order to reach the specific goal, that is, to identify whether Francisco Campos can be considered an authoritarian or totalitarian intellectual, it was essential to carry out an investigation of convergent points of thought campers with the political theology of Carl Schmitt, confronting them with the categories totalitarian views presented by Hannah Arendt. We also take advantage of Giorgio Agamben, especially his state of exception. The problem with the investigation lies in the fact that Brazil has always been lacking in its own political thinking, so much so that Francisco Campos, seeking to construct original thinking, flirted with authoritarian regimes and European totalitarian theories. However, to what extent did this contact with anti-liberal ideologies converge in the formation of his conservative thinking. In short, it takes care of a bibliographic and documentary research, since the proposal required an analysis of the works and writings to understand the formation of camper thinking, as well as the influence suffered by the Schmittian and integralist theories. In this complex scenario, it can be concluded that Francisco Campos, although conservative authoritarian thinking and advocate of dictatorship as a form of consolidation of a nationalist government, in opposition to liberal ideas, cannot be accused of totalitarianism, even if both Francisco Campos and Carl Schmitt are contemporary and some points of their theories may even converge.

The following study analyzes the educational processes which happen in Rodas de Leitura in a correctional facility in the state of São Paulo, Brazil. Our interest for the subject has arrived from our participation through unscholarly activities, in some correctional facilities, where we could notice that the gatherings taking place were spaces for personal improvement, exchange experiences, places for people to unburden themselves and that can change ways of thinking, perceiving and forge opinions. Driven by those experiences, we have built our research object: Which educational processes can the social practice Roda de Leitura develop in a space of deprivation of liberty? Guided by this question, we have defined our general goal: to present the educational processes which flow from the social practice of Roda de Leitura that happens in a correctional facility in the state of São Paulo. It is a research of qualitative nature and the data collection was done based on the principle of participating observation. The observation, the informal conversations and the gatherings which happen in Roda de Leitura were used to gather data which were organized in Field Journals. Questionnaires were applied to the collaborators with the goal of characterizing the group and exposing their perceptions about the Roda de Leitura and its educational processes. The data were organized, and four analysis focuses were determined: The meaning of Roda de Leitura, The contributions from Roda de Leitura to the school, The mediator role of Roda de Leitura, The organization of Roda de Leitura in the collaborator’s perspective. The analysis has shown that the Roda de Leitura allows the people to have pleasant dialogues, to interact amongst themselves, to disagree, agree and to partake in the construction of new knowledge. The analysis also shows that the mediator as an emancipating educator promotes situations for identity formation, self-esteem and self-reliance. The participants show themselves eager to keep having the Rodas, suggest other ways of doing them and show solidarity to the other people who inhabit the other areas of the correctional facility.

Databases and database systems are essential to modern life. In a scenario of increasing data handling arose the need to find newer ways to store and process data that are able to cope with the rapid evolution of society. NoSQL databases are an alternative to this scenario but the lack of standard between each database implementation increases the difficulty to perform some tasks when compared to a SQL database. To solve this problem, this paper increments the work of Noguera e Lucrédio (2019), using the query language it improves the join operation and implements the operations Cartesian Product, Selection and Projection that were proposed by Parent e Spaccapietra (1984). In order to make the metamodel creation process more friendly, a textual representation was created for the metamodels and a parser for generating code compatible with the algorithm. Two software systems were analyzed to validate the MongoDB code generated by the algorithm and to check if the query result conforms to the structure defined by the algebra. The query performance was also analyzed, comparing it to the performance of queries that were handcrafted by a Software Engineer. This paper shows that the ER algebra is compatible with document-oriented NoSQL databases and that automated query generation does not significantly affects performance.

This thesis proposes to understand how determined bodies are valued as negative in the work The Silmarillion, from J. R. R. Tolkien, especially because there is a marked division of different peoples and bodies in it, as well as an ethical and aesthetical relation, in which the author created one of the most complex and vast fictional universes for developing languages, ages, peoples, maps, and cosmogony. The theoretical-methodological basis of this work is based on the studies developed by the Russian philosopher of language Mikhail Bakhtin and the other thinkers of the Circle, mainly on the concepts of alterity, body, and grotesque realism. Thus, starting from a historical materialist methodology, the body, as a social construct, is part of an I-other relationship, being valued. Those who somehow transgress the current rules of a world are called monsters, building an aesthetical and ethical withdrawal from the human that acts as a process of social exclusion and extermination. Concomitantly, in the ethical world, one can observe how these mechanisms of social exclusion and death are part of the racism towards the black population. That said, to a comprehension of that valuation in art and in life, this work compared news about racism in Brazil. Thus, it is concluded that when one observes these bodies from a bakhtinian perspective, he understands that they are grotesque bodies, once they are a transgression and all those who are oppressed, negatively valued, excluded and killed, they are so from their bodies and their experience for breaking a current rule. Therefore, existing is a profoundly revolutionary act, for it is to resist.

Ionomeric polymer-metal composites (IPMCs) are smart materials, which have a metal/polymer/metal sandwich-like structure and are capable to deform in response to electrical stimuli and vice versa. In addition, they have low density, flexibility, biocompatibility and low drive voltage. Therefore, they are promising materials for a wide range of applications, such as actuators, sensors, and as artificial muscles. The operating mechanism of these devices consists of the migration of hydrated ions within the polymer's ionomeric channels in response to an electric field generated after the application of a bias between metal electrodes. For this reason, its electromechanical performance depends on several factors, such as electrical stimulus, hydration level of the polymeric membrane and counterions. Therefore, in this work, traditional (electrical, morphological and deformational) and complementary techniques (SEM, TGA and EIS) were used to characterize artificial muscles under different conditions of electrical stimulus (1 to 5 V), relative humidity (30% at 90%) and containing counter ions of varying sizes (H+, Li+, Na+ and K+) and distinct chemical characteristics (1-butyl-3-methylimidazole - BMIM+), in order to elucidate and understand their electromechanical behavior. Also, a method of video analysis was also used in conjunction with a video analysis and modeling tool built on the Java Open Source Physics (OSP) framework, allowing for a more accurate electromechanical behavior analysis. Results showed that the electromechanical behaviour, electric charge storage, and the Coulombic Efficiency of the devices increased with the reduction of counterion ionic radius and increase of the hydration level of the polymeric matrix. The mechanical performance decreased with the number of cycles, showing a limited life cycle for the device. The image analysis proved to be efficient, effective and low-cost technique.

This thesis deals with dynamics of life and death at the margins. Based on fieldwork carried out in a large slum in the city of Belo Horizonte, here called Morro da Luz, an analysis is made about the coexistence of different regulatory regimes in territories in the urban periphery, that is, the interaction between different logics, morally informed, to organize symbolically and materially the relations of sociability and the classifications of what is or is no longer socially acceptable, desired or disapproved. Throughout the text, it is demonstrated that, currently, there are three main normative regimes operating in Luz and, possibly, in other similar territories throughout Latin America: state (in its multiple and often antagonistic facets); crime (which, in Belo Horizonte, is characterized by the presence of several small groups that compete with each other, but which are still capable of building a criminal discourse unit); and church (especially the many evangelical strands). These three normativities build symbolic relationships among themselves that alternate between dispute and articulation, forming a normative triangulation that acts, based on the sharing of the appreciation of the notion of respectability, as a mechanism for the daily moral analysis of people and behaviors. These dynamics are made possible by a broader scenario, typical of post-colonial nations, of production and maintenance of economic and rights inequalities, which, in the favela, make subjects in an eternal negotiation between life and death.

In the current dissertation, we study the mixture regression models and present two Bayesian methodologies for their estimation. The first one considers the number of components is known and we propose the use of two Bayesian model selection criteria, DIC and EBIC, to identify the number of components. In the other one, we propose a reversible jump algorithm with splitmerge steps that estimates parameters and the number of components. We apply the proposed methodologies and also the EM algorithm, already available in R package, for simulated dataset and for Brazilian educational data, studying the relationship among the Basic Education Development Index and some socioeconomic and demographic data.

The objective of this thesis was to investigate, to analyze and to present the many aspects relative to the socioenvironmental impacts of the sugarcane agroindustry on the ways of life of the Nossa Senhora do Chumbo quilombola community, through the perceptions of community members, and taking into account gender, class and race aspects. The community is located at the northern region of the Mato Grosso Pantanal, known as the “Cerrado do Pantanal”, located in the municipality of Poconé, in the south-central portion of the state of Mato Grosso, in the Upper Pantanal microregion. Qualitative social research procedures were used in the research, as life stories and interviews with social agents selected by their representativeness in the community in relation to their experience with sugarcane socio-environmental implications in the region. Conflicts in the region began with the implementation of the sugarcane agroindustry, with unequal disputes between residents of communities that had and have their culture, identity and territory threatened by dominant groups, especially agribusiness. In the region, the deforestation carried out for the introduction of sugarcane monoculture and livestock have motivated conflicts between the owners of these large enterprises and the social agents who live from family farming and working in the mines. From the 1980s through 2012, we realized that these agents were subject to expropriation. As in other locations, this expulsion produced migration to search for work, which made the sugarcane agroindustry in the community a destination for this workforce composed by local people and migrants from the Northeast. The social and environmental impacts resulting of the implementation of sugarcane agro-industry in the community weigh disproportionately on different groups in this territory due to social and economic vulnerability, characterizing environmental injustice.

The black lion tamarin (Leontopithecus chrysopygus) is at the endangered of extinction and as a conservation strategy we have the ex situ management that aims to maintain a genetic and demographic bank of this species, seeking to reproduce these animals to reintroduce them into their natural environment when necessary and possible. Regarding foraging, the black lion tamarin consumes fruits, exudates, prey and flowers in the natural environment; capturing prey through manipulative foraging. However, the composition and the mode to provide their diet in captivity are different from what would be found in the natural habitat, and to don’t lost the foraging behavior it is necessary to make this aspect closer to the wildlife by food enrichment. Food enrichment decreases abnormal behaviors, stimulates new activities and the expression of the species' natural behavior that favors animal welfare. For this reason, the present study aimed to measure the influence of feeding enrichment on the foraging behavior of the black lion tamarin. To that end, 19 individuals were analyzed in two different environments and we made feeding enrichment by offering items from the natural diet of the species (jerivá fruits and tenebrio beetle) and from the captivity diet (fruits, vegetables and ration) in food enrichments, generating the total of 480 hours behavioral observation divided into 4 situations: without enrichment, with enrichment of the natural diet, with enrichment of the captive diet and with natural and captivity combined enrichment. Were observed 106 behaviors, grouped into 15 categories. In general, the enrichment with greater interaction was with captive items and as the important result it increased affiliation behavior compared to the situation of natural enrichment. Natural enrichment, on the other hand, increased feeding behaviors and decreased stopped behavior. The combination of enrichments with natural items and those of routine items decreased behaviors such as standing, locomotion and physiological categories. In addition, all situations had the interaction with enrichment and the ingestion of enrichment food increased significantly. Therefore, the results show that all the enrichments presented were important to stimulate natural behaviors and to improve the quality animals life, indicating a trend towards animal welfare.

Gymnastics for All is characterized by a manifestation of body culture that brings together the different interpretations of Gymnastics integrated with other forms of body expression in a free, creative and non-competitive way. In this sense, in order to give greater visibility to the new possibilities related to the teaching of Gymnastics for All and to contribute for this practice to be incorporated into Physical Education at school, this research aimed to develop and analyze an intervention process in class School Physical Education with Gymnastics for All content. The methodology based on the qualitative approach constituted a process of action research. Eighteen students from the 3rd year of elementary school in the early years of a municipal public school in the interior of São Paulo participated in the study. We carried out a total of thirteen interventions in a period of two months, corresponding to a two-month term. The technique for data collection involved: observations of classes recorded in diaries, which were recorded and transcribed for later analysis of the facts that occurred during the interventions. After intense reading of the data and articulation with the literature, we built two categories of analysis, being: 1. Pedagogical Teaching Processes; 2. Human Formation. Among the most outstanding results in category 1 are the teaching procedure that playfully and creatively contributed to the development of the contents organized and proposed according to the didactic pyramid for teaching Gymnastics for All, contemplating the manifestation of conceptual, procedural knowledge and attitudinal. With regard to category 2, Human Formation was subdivided into two subcategories called Advances and Setbacks in Human Formation. As the most noticeable advance, we highlight self-confidence. However, collective action as well as cooperation are also noteworthy, given that the students worked as a team for a common good, in this case, the choreographic composition. In the subcategory Retrocesses, the situations of disrespect and disorganization stood out for generating moments of indiscipline and demanding a directive teaching action to resolve conflicts. Analyzing the planning and intervention process, we identified Gymnastics for All present in the context.

The objective of this thesis was to analyze and contrast the existing methodological models within the geographic information system, its techniques and indicators for environmental urban planning, aiming at building bases for smart cities To achieve the objectives, the following objectives were proposed: (a) elaborate an inventory of erosive processes in the study area; (b) generate a collection of cartographic documents; (c) build training bases for different models of artificial neural networks (one-layer perceptron neural network, multilayer perceptron neural network and ANFIS); and discuss the methods and methodologies for environmental urban planning The study area is the Monjolinho River Basin inserted in the municipalities of São Carlos and Ibaté, with an area of approximately 273,77km2. The method used included: the elaboration of an input data structure for Matlab®️, extracted from a data matrix of the maps elaborated in the ArcGIS®️ 10.5 desktop version software. The training was carried out in two phases, the first with a structure of 203,496 points, extracted from a regular matrix of 100x100m, in the second phase a new training was done, with some modifications in the structure, two models were trained, design 1 with crisps data and design 2 with data normalized between 0 and 1, using the perceptron method with a layer, with a 30x30m matrix, with 13,152, 355 representing erosions. In the process, the removal of tuples with invalid data (for example, values -9999), counting the number of occurrences of repeated tuples and ending the removal of repeated tuples, all these steps were done to equalize the imbalance of the classes, totaling 710 “non-erosion” and 355 “erosion” maintaining a 2 to 1 ratio With the new training, a model was sought to more accurately represent the occurrence of erosive processes, so it is necessary that the values that represent false negatives are low, as it is critical for the system to indicate that there is no erosion when it actually exists. In this sense, the perceptron network of design 2 was the one that presented the best results, presenting less occurrence of false negative values than design 1.
