The present research intends to map characteristic traces of the organizational changes occurred in educational instituitions, especially brazilian ones, in the last decades of 20th century. The present investigation’s emphasis is to study how the capitalist’s logic, throughout the neoliberalism, proliferates in the educational systems. The investigation originally came from a analysis of the statements contained in a educational document, and after that it were established the conetions with other contexts, thus revealing a mundial tendency. The document in question, which title is “Melhores Práticas em Escolas de Ensino Médio no Brasil”, is a research report carried out by Instituto Nacional de Pesquisas Educacionais Anísio Teixeira (a federal autarchy associated with Ministry of Education) in partnership with Inter-american Development Bank, in 2010. The research was divided in three investigative dimentions: documental, historical-sociological and philososophical. The document’s internal problems guided the establishment of the references for analysis. From the historical-sociological perspective, the research was supported by Christian Laval’s analysis, in his book School is not an enterprise: the neoliberalism assaulting public education, in which the sociologist traces the problematic contours of neoliberalism’s influence in the educational systems. From the philosophical perspective, the analysis was based in Gilles Deleuze’s diagnosis, in Post-scriptum about the control societies, a text in which the philosopher describes how the passage from disciplinary societies to control societies produces institutional and subjectives transformations. This mutation of domination forms, described by Deleuze, is strongly related to a technological transformation: the emergency of information technologies. The analysis was conducted by what we called cartographical method. This one was inspired by the concept of cartography, developed by Deleuze and Guattari in A thousand plateaus. We concluded that the contemporary transformations can be understanded as a result of a capitalist axiomatics’ rearticulation. In this new mode of realization, the institutional school’s specificity is deterritorializated, to be reterritorializated in the enterprise form. The school loses its relative autonomy to economical field, that is characteristic of the disciplinary regime, and starts to compose directly the financial capitalisms’ informational flows. In this paradigm, educational is no longer seem as a right, but as a merchandise. This conception implies a destruction of the school’s anthropological function – insert the new generations in a common symbolic universe. We understand that it is a scientific’s research duty to contest the doxa of its field in a determined historic moment. Therefore, we question education’s representation as a merchandise, and we reaffirm school’s specificity and the institutional function in ensuring the universal right to culture.

In the past few years, the self-styled No Party School Movement (MESP) and their discourses have risen throughout the Brazilian scene. It is understood that the MESP has the potential to cause drastic and at the same time retrograde changes in Brazilian education, especially over the school and in the way it relates itself with the students. Hence, to comprehend the historical construction of the MESP as a discourse, the concepts on which it is based and the types of subjects it seeks to produce and silence, configure an important topic of study in contemporary times. The research developed took the discourses supported by MESP as object of analysis. The analysis undertaken was supported by Michel Foucault's contributions regarding his studies on the production of truths and discourse. In addition, a study was developed on the appropriation and meaningfulness adopted by MESP regarding the concept of ideology, one of the pillars of the Movement, as well as its self-denomination as a social movement. The results provide a broad understanding of MESP as inserted in a neoconservative and neoliberal discursive field, defending an antidemocratic and excluding education project. Consequently, it points to the effects of MESP on teaching subjectivities in terms of control, repression and the construction of the other as a threat.

Nowadays, technological evolution has allowed advances in several areas, especially in healthcare. Digital transformation in health has brought benefits to both professionals and patients. What was possible to do only with high-cost and unwieldy biomedical equipment, has been popularized with the emergence of wearable devices. This technology allows clinical monitoring beyond medical offices, being able to be incorporated into the daily life of patients and working as another tool for prevention and promotion of health and well-being. Among the various features present in wearables is pulse oximetry. Through this non-invasive technique, it is possible to measure physiological parameters, such as oxygen saturation (SpO2) and heart rate (HR). However, the way pulse oximeters are developed and used directly influences the quality of the information provided to the user. Photoplethysmographic (PPG) signals from pulse oximeters are susceptible to noise, which is largely caused by user movement during monitoring. These motion artifacts can cause measurement errors and false alarms. In order to mitigate these issues, this work proposes an algorithm based on artificial neural networks (ANNs) capable of detecting and reducing the undesirable effects produced by noise in PPG signals. The performance of this algorithm, called OxiTidy, was compared with three other approaches — raw, discrete Fourier transform (DFT) and simple moving average (SMA) —, using data from 17 healthy volunteers. OxiTidy identified the intervals where the measurements were incorrect and estimate new SpO2 values with a good approximation to the readings performed by a pulse oximeter certified by the Brazilian Health Regulatory Agency (Anvisa).

Urinary incontinence (UI) and overactive bladder (OAB) are highly prevalent and affect women of all ages. Both UI and OAB can be diagnosed from the patient's report. In the case of BH, the report may be related to the urgency to urinate, increased urinary frequency, waking up at night to urinate; the report of UI is related to loss of urine due to effort, urgency or both. The King's Health Questionnaire (KHQ) is a questionnaire that aims to verify the quality of life of women with urinary symptoms and has a survey of the presence and severity of symptoms, it is translated and validated for the Brazilian population, however, some properties of measures are still had not been evaluated. In addition, the assessment of the patient's health status can be important for the assessment of utility and consequently be used for economic health assessment, which are important in the decision-making of health managers. Thus, the assessment of health status can be performed using a general or specific quality of life questionnaire. For women with urinary symptoms, utility can be assessed by the Short Form six dimensions (SF-6Dv1) or the five-dimensional KHQ (KHQ-5D). Thus, this thesis aimed to evaluate the properties of KHQ measures and compare the measures of utility of a general questionnaire (SF-6Dv1) and a specific questionnaire (KHQ-5D) for women with UI. The observed results involved a Brazilian version of the KHQ, called KHQ-Br, composed of a structure with five domains, Limitations of daily life, Personal Relationship, Emotions, Sleep/Energy and Severity Measures. In addition, it was possible to observe good reliability, moderate to strong construct validity, in addition to being responsive to physical therapy intervention. Regarding the indexes based on preference, it was possible to observe interaction on the set of values in the comparison between different countries and the presence of UI, also an effect between countries and an effect between groups with and without UI with the SF-6Dv1. In addition, it was possible to observe a small correlation between the indices obtained by a general questionnaire (SF-6Dv1) and a specific questionnaire (KHQ-5D). Conclusion: The Br-KHQ can be composed of a structure with five domains, showed good reliability, moderate to strong correlation of construct validity, and is responsible for physical therapy intervention. In health status assessment, a generalized questionnaire, such as the SF-6Dv1, is preferable for utility assessment, while a specific questionnaire, such as the KHQ-5D, should be used with caution until a new set of values is implemented for health status.

In line with the objectives and purposes for which they were created, it is in the genesis and in the attributions given to the Federal Institutes “to develop extension activities according to the principles and purposes of Vocational and Technological Education (EPT), in articulation with the world of labor and social segments, and with an emphasis on the production, development and dissemination of scientific and technological knowledge” (BRASIL, 2008). In this sense, by establishing the articulations of the EPT through academic and technological knowledge and the surrounding community, the University Extension is understood as spaces for the production of knowledge and the dialogue of systematized knowledge between the academic and the popular that result in the democratization of the knowledge. In this perspective, the starting hypothesis considers the fact that the IFPA - Campus Rural de Marabá (CRMB) is located within a settlement area and both are symbols of the achievements of the struggle and effective action of social and union movements in the countryside for the right to land. and the EPT, resulting in a public education institution based on the concept of rural education, agroecology and pedagogical alternation. Therefore, these characteristics changed the logic of making the University Extension, making it more transformative. In this research, the question is: Have university extension practices for agrarian reform settlers in the southeast of Pará Amazon in the EPT experiences in the IFPA-CRMB field have been marketing, assistentialist and/or transformative? In order to answer this question, the objective of this thesis is to understand the extensionist practices affirmed to the settlers in the EPT field experiences, taking as a case the IFPA-CRMB and the Agrarian Reform Settlements. For this, the research combines four distinct and interconnected studies. The first study describes the struggle for land and the constitution of rural settlements in southeastern Pará and the presence of the IFPA-CRMB within this territory; second, it seeks to discuss the conceptions and foundations of the EPT through the analysis of the work and education category, which give us support to discuss the ideas that were being established and the factors that influenced and legitimized the conceptions of the EPT in the face of the interests of the ruling class and the training the workforce in the stages of Brazilian capitalist development; The third seeks to base itself on legal and theoretical frameworks that deal with the concepts and conceptions of University Extension and its identity, as well as its constitution over time and its relationship with teaching and research and the place it occupies today in EPT ; and the fourth presents the University Extension at EPT at IFPA-CRMB through its projects, narratives and experiences. As part of this stage, a study was carried out of five extension projects carried out with the Agrarian Reform settlers with a focus on the dialogue of knowledge. For the scope of the research, the investigation took the perspective of historical-dialectical materialism, and used as a methodological route: bibliometrics, document analysis, semi-structured remote interview and virtual questionnaire. The results achieved allow us to conclude that the university extension carried out in the Settlements, despite the limitations found, can play a significant and transformative role in these territories in order to overcome inequalities. Studies show that university extension, when constituted from the constant interaction between the IFPA-CRMB, social movements, settlers and all democratic forces in society, can gain contours that transcend a welfare and/or marketing extensionist conception.

Thermal insulation and fire protection are two of the most critical features affecting energy efficiency and safety in built environments. Together with the associated environmental footprint, there is a strong need to consider new insulation materials. Tannin rigid foams have been proposed as viable and sustainable alternatives to expanded polyurethanes, traditionally used in building enveloping. Tannin foams structure result from polymerization with furfuryl alcohol via self-expanding. We further introduce cellulose nanofibrils (CNFs) as a reinforcing agent that eliminates the need for chemical crosslinking during foam formation. CNF forms highly entangled and interconnected nanonetworks, at solid fractions as low as 0.1 wt %, enabling the formation of foams that are ca. 30% stronger and ca. 25% lighter compared to those produced with formaldehyde, currently known as one of the best performers in chemically coupling tannin and furfuryl alcohol. Compared to the those chemically crosslinked, our CNF-reinforced tannin foams display higher thermal degradation temperature (peak shifted upward, by 30–50 °C) and fire resistance (40% decrease in mass loss). Furthermore, we demonstrate partially hydrophobized CNF to tailor the foam microstructure and derived physical–mechanical properties. In sum, green and sustainable foams, stronger, lighter, and more resistant to fire are demonstrated compared to those produced by formaldehyde crosslinking.

The right to housing has been discussed more widely in Brazil since the 1980s, when popular movements for the right to live in a dignified manner emerged. As a result, debates on urban property and its social function also gain space in the urban policy scenario. When observing the country's housing deficit, it is clear that this discussion is still current. With the approval of the City Statute in 2001, new tools appear for the organization of urban territory and enable the production of housing of social interest. In this sense, this work addresses issues of the right to the city, mainly in the context of the Federal Constitution of 1988, discusses the social function of the city and property, especially that of public urban property, and argues that the government can provide housing of social interest as a way of fulfilling the social function of the urban voids of public property. From the case study of the Minha Morada Program, a local initiative of the municipality of Araraquara-SP, it analyzes the program that allocates empty urban areas of public property to a program of urbanized lots, in view of the insufficiency federal housing policies and the inadequacy of the social profile of the population that makes up most of the deficit. The results demonstrate that by allocating areas well served by infrastructure and public facilities for a housing policy that serves the most socioeconomically vulnerable population, the program seeks to fulfill the social function of public urban property, promoting decent housing within the local context, meeting the specificities of the city's housing deficit.

This study has as perspective the promotion of data that contribute to the improvement of the evaluation practices, as well as to a review in the approaches of the evaluation theme in the teacher education courses. Our goal is to analyze the understanding of teachers about the assessment of learning approached in the process of initial training and the consequences of the discipline of Educational Assessment in their professional performance. In this sense, the research contemplates as specific objectives the necessity to: investigate what teachers understand by evaluation, what they defend and what they propose; identify the evaluation practices mentioned by teachers in the teaching-learning process; punctuate the limits and the reaches of the evaluation practices pointed out by teachers in their professional performance. The research is based on the epistemology of practice as a theoretical strand and on authors such as: Tardif (2000, 2012), Nóvoa (1992, 2017, 2019) and Gauthier et al (1998), to discuss the knowledge that underlies both the training and the professional performance of teachers; in addition to Freitas (1995, 2009), Hoffmann (1995, 2005, 2008), Luckesi (1995, 2000 e 2011), Vasconcellos (2006) and Villas Boas (2011), who deal with learning evaluation and its implications in Basic Education. Based on a qualitative approach, Bogdan and Biklen (1994), Lüdke and André (1986) and Gil (2008), and an exploratory-descriptive study (SELLTIZ et al, 1965), the analysis was developed with the completion of questionnaires applied to teachers mostly working in the public education system, graduates of the undergraduate courses of a higher education institution, an Autarchy under private law in the city of Avaré, São Paulo, who attended the subject Educational Assessment, offered by the institution. The analyzed data were organized into four category of analysis: 1) identity profile of professional training; 2) evaluation of learning, curriculum and initial training; 3) evaluation of learning and professional knowledge; 4) evaluation of learning and pedagogical practices. The results point to a probable contribution of the discipline of Educational Assessment in the initial training and possible reflexes on the professional performance, promoting the appropriation of concepts incorporated into the teachers' speeches, from a diagnostic, formative and procedural perspective, collaborating with the diversity of processes and allowing a more reflective and investigative posture focused on student learning.

Suspended particulate matter in the air represents a significant health risk, potentially leading to severe respiratory diseases. Bioaerosols, including viruses, bacteria, and fungi, are also part of this particulate matter and can be inhaled, causing illnesses such as influenza, tuberculosis, and COVID-19. Electrospun filters are particularly effective for capturing these particulates due to their high surface area. Additionally, these filters can be enhanced by incorporating nanoparticles and surfactants into their fibers, which improves their filtration efficiency and imparts biocidal properties. This study focuses on developing a filtration medium using polyacrylonitrile (PAN) combined with compounds that provide biocidal characteristics and assessing how these compounds affect filtration performance. The compounds investigated include zinc oxide (ZnO) nanoparticles and surfactants like cetylpyridinium chloride (CPC), cetyltrimethylammonium bromide (CTAB), and sodium dodecyl sulfate (SDS). Electrospinning was employed to produce nanofibers at the nanometer scale. In the initial phase, electrospinning parameters were optimized using only ZnO. Nanofibers made from PAN at varying concentrations (8%, 9%, and 10% w/w) were combined with ZnO nanoparticles at different levels (5%, 10%, and 15%). Scanning electron microscopy (SEM) was used to measure fiber diameters, and a 2³ factorial design was applied to determine the optimal conditions for PAN and ZnO concentrations and voltage to produce nanofibers with the smallest diameters, enhancing filtration efficiency. In the subsequent phase, the optimized conditions were used to produce nanofibers containing 15% ZnO nanoparticles and surfactants (CTAB, CPC, and SDS) at concentrations of 1.5%, 2%, and 2.5%. Characterization of the solutions was conducted for viscosity and conductivity, and the resulting filters were analyzed using SEM, FTIR, TGA, DSC, and contact angle measurements. The bactericidal and virucidal activities of the filters were also assessed. The findings revealed that the filtering media had nanofiber diameters ranging from 431 to 712 nm, with filtration efficiencies reaching up to 99.80% and a pressure drop of 170 Pa. Furthermore, filters containing surfactants showed bactericidal effects greater than 99% against Staphylococcus aureus and Escherichia coli, and virucidal effects exceeding 99% against SARS-CoV-2.

This work aims to analyze, in Indaiatuba, a medium-sized city in the interior of the State of São Paulo, the relationship between the implementation of projects dedicated to social housing, from the first projects in the 1970's to the most recent, produced by the Program Minha Casa Minha Vida until 2020, and the consequences arising from these projects in the urban environment. It seeks to assess the role that legislation – federal and municipal – played in these cases, and how urban fragmentation impacted the formation and configuration of these spaces.

Mechanical forming operations are developed in several applications in industrial environments and are divided into some different operations, including cutting, bending, forging. Among the various processes, the bending operation, although quite simple, presents a phenomenon that appears when the load is relieved, and this phenomenon is known as springback. The springback, which is also known as elastic material return, causes the material to partially return to its initial state that it presented before the bending process, which is a problem of great relevance in the industrial environment, which provides a gap research in order to minimize its impacts. The goal of this work is to propose alternatives to predict the elastic behavior of aluminum sheets when undergoing the bending process, suggesting possible changes during the process, such as the application of forces and adjustments to tools and molds. The applied methodology consists of experimentally studying the behavior of the springback during the application of folds in aluminum plates and comparing its results using numerical simulation resources with finite elements applying the Abaqus® software for the modeling and simulation of the process. A metallographic analysis must be performed before and another after the test to present the study of the microstructural variation in line with the springback behavior. Through the analysis of these, it is expected to be possible to propose significant changes in the process so that the negative effects of the emergence of springback are minimized, thus elaborating extended variations for a range of fold operations using the same materials. It was possible to conclude that the compensation proposal presented satisfactory results in the numerical and experimental analyzes using the solution proposed in the course of the work, which al inserting changes in the geometry of the matrices provided bending results close to the expected values.

Lubricants are among the many products whose manufacture is highly dependent on nonrenewable fossil resources, with high levels of production and a vast marketplace, so they are the focus of many environmental laws around the word. Currently, this market includes some biobased products, known as biolubricants, although they represent a very small fraction of this sector and have certain limitations. Studies concerning the development of new products, raw materials, and processes are essential for the expansion and commercial success of biolubricants. Therefore, the aim of this work was: evaluating the production of biolubricant base stocks such as fatty acid isoamyl esters (FAIEs) from soybean oil deodorizer distillate (SODD) as a fatty acids source, together with isoamyl alcohol (a byproduct from bioethanol fermentation and the main constituent of fusel oil), catalyzed by free Eversa Transform 2.0 lipase and Pseudomonas fluorescens lipase (PFL) immobilized by the hybrid nanoflower (hNF) method. Experimental design and response surface methodology were applied to define the parameters for PFL immobilization using hNFs (hNF-PFL), viz. protein concentration, metal concentration and immobilization pH, and for FAIEs production, viz. SODD/isoamyl alcohol molar ratio, reaction temperature, the enzyme mass and secant salt mass (for the reactions with hNF-PFL). Studies of the incubation step of the synthesis using hNF-PFL enabled the incubation time to be reduced from 72 h (static immobilization medium at 25 °C) to just 20 min using ultrasound, without losses of immobilization yield (IY) or immobilized activity (IA). The optimized IY and IA values for hNF-PFL were 54 and 64 TBU%, respectively. The hNF-PFL showed high operational stability, maintaining practically the same reaction yield (RY) values during 8 cycles, over a total of 192 h. At the 10th cycle (total of 240 h), the material presented relative RY of 80%, compared to the earlier cycles. In the production of FAIEs using ETL 2.0 with molecular sieve (for moisture control) at 39 and 9 wt.% (molecular sieve mass / SODD mass), RY values of 50 and 70 wt.% were achieved, respectively. When hNF-PFL was employed in the FAIEs synthesis, RY of 64 wt.% was obtained, without the use of a moisture control agent. Products of partial conversion of SODD into FAIEs, catalyzed by ETL 2.0, with RY of 44 and 55 wt.%, and catalyzed by hNF-PFL, with RY of 56 and 57 wt.%, presented physicochemical characteristics similar to those of commercial biolubricant base stocks. Therefore, this doctoral thesis has the potential to contribute economically to the lubricant market through an environmentally friendly enzymatic process for the synthesis of a base stock from by-products of the national industry.

Historically education aimed at the working class has not been a priority in Brazil. The expansion of the offer of Elementary Education only began to receive some attention from the national political class from the 1930s onwards, due to the need to train a workforce to boost the economic development project established by the government of Getúlio Vargas, guided by the binomial “urbanization-industrialization”. The universalization of Basic Education (Child Education, Elementary School and High School) is still a challenge to be effectively faced. Higher Education, in turn, has become an almost exclusive privilege of the ruling class, systematically denied to the working class, especially to peasants. In the perspective of undertaking the research, we defined as a first objective to verify the importance of scientific production and the contribution of the Group of Studies and Research in Education in the Field of the Federal University of São Carlos (GEPEC/UFSCar) for the development and improvement of public education, in especially that of the countryside; and as a specific objective to analyze the relationship between Marxian/Marxist theoretical foundations on education for rural populations and Historical-Critical Pedagogy (PHC). The methodology chosen for the development of the investigation had two fronts. The first consisted of a bibliographic approach, where we searched for the productions developed by GEPEC. The second methodology included a documental research, we sought to locate official documents that allowed us to understand the historical context of the creation of the Group. We conclude that GEPEC constitutes an important space for discussion about the realities that characterize life and work in the countryside through analyses, interpretations and reflections on education for rural populations, as well as for the knowledge and recognition of the importance of action and the role of social movements in the struggle and defense of agrarian reform and education.

The objective of the present work is to improve the performance of a Stimulated Raman Adiabatic Passage (STIRAP) in a 3-level system by applying successive non-selective measurements throughout the evolution (exploiting the properties of the quantum Zeno effect), so that a given quantum state is protected as the total time of evolution is decreased. This is a problem of great interest because it may take part in very important quantum techonologies such as the charging of quantum batteries and the optimization of Adiabatic Quantum Computing (AQC) processes. Through computer simulations it's been verified that it is possible to significantly reduce the total time of the population transfer via dark-state without taking the system off the adiabatic regime.

In this work we tried to approach how the land uses for development of economic activities and housing in rural areas can change the environmental dynamics in relation to the geomorphology, in an analysis integrating relief and water resources. Considerations were also made about the Sorocabuçu Basin is floodplain sector, which is within the urban perimeter. The basin is located predominantly in the rural area of municipality of Ibiúna-SP, which is a Sorocaba River tributary, contributing to supply the Itupararanga Reservoir. Thus, the study area is configured in a sub-basin of Sorocaba/Médio Tietê Basin. It supplies water to the municipalities of Ibiúna, Votorantim, Sorocaba and Mairinque. In addition, it is an economically important area for the municipality, due to the intense development of temporary agricultural crops, which is the main economic activity in the municipality. With respect to the methodological procedures, stages of analysis about relief, hydrography and environmental impacts were carried out, through the elaboration of thematic maps, interpretation of satellite images and field observations. During the research, the characterization of relief and drainage were carried out; four distinct geomorphological compartments were identified; analysis of chemical and physical parameters of main courses of the Sorocabuçu River; in addition to the identification of responsible elements for alterations in relief, as well as the water flow and quality.

This dissertation aimed to analyze the multidimensional (HAESBAERT, 2003) and polymorphic (BRENNER, 2018) process of the United Kingdom's exit from the European Union through Brexit, initiated in 2016 and consolidated in 2020 after years of negotiations. The focus was on the legal-political dimension of the territory (material and symbolic) through the reterritorialization of British sovereignty to the detriment of the supranational deterritorialization of the European regional bloc. Furthermore, the culturalist and economic dimensions of Brexit were also addressed as related axes. A geopolitical scenario of contradictions and conflicts, dualities and dichotomies: the Leave campaign and the Remain campaign, British autonomy and insular identity versus the heteronomy of institutions, nationalism against supranationality, local versus global.

The single point incremental forming method performed without die support is suitable for small batch and prototype product manufacturing due to the lower cost involved in its tooling acquisition, simplicity and flexibility of implementation. This concept makes the process viable for diverse applications in the medical, aerospace, and automotive industries, when largescale production of a product is not the priority but rather the individual analysis of a part or prototype construction and the manufacture of customized products. For frequent applications in industry the lack of some process information such as referential parameters of vertical displacements in the z-axis and velocity of displacements in the x and y axes makes it limited, they do not guarantee the appropriate guidelines that can ensure the use of incremental stamping on an industrial scale, which avoids wasting machine time and material resources in case of failure. To meet this need, the finite element method was used to perform the numerical analyses as an aid for a perception of the process particularities, applied in experiments that used a 0.4 mm thick plate of aluminum QQ-A-250/5 (2024-T3) as raw material and manufactured tooling composed of clamping brackets and dedicated tools, parameters were established based on limit diagrams that ensured the execution of manufacturing by incremental stamping of products with a good quality in surface finish. Using the computational model created and the information obtained regarding the final thickness of the material and its deformations after the conformation and after the simulations, parameters were obtained that inform the possibility of performing the operation. In the experiments performed, there was a guarantee of finalizing the depth determined when the tool with a 3 mm tip radius was used in three cases studied, being them with displacement in the z axis of 0.2 mm, 0.3 mm, and 0.4 mm. In the parts made with displacement in the z axis of 0.5 mm there was the appearance of rupture, which caused the interruption of the operation. In the cases where the tool with tip radius of 6 mm was used, all parts presented rupture, which compromised the performance of the operations. The use of the parameters that enabled the parts to reach the proposed depth, demonstrated by means of the failure prevention method applications in other profiles. All the data gathered were used to construct a method for analysis in the prediction of structural failures that may occur during the process, and by this method it was possible to predict the realization or not of the specific cases presented.

The present dissertation focuses on the learning characteristics of beginning school principals. The 5 professionals participating in the research were approved in the public contest of tests and titles at the State Department of Education of São Paulo-SEDUC, in the year of 2018. The research question of the study was: How is the learning of beginning school principals characterized? This is an exploratory study, of a qualitative nature, based on the analysis of the prose (ANDRÉ 1983, 2018). The theoretical contributions of the research were: the context of school administration; the public school as a place of work, of learning through teaching, struggles and contradictions; characteristics of the beginning in the position, knowledge and permanent learning. The professional characteristics of the work of school administration in contemporary times, the trends for the training of principals and the challenges of work in the face of social demands in favor of an education that meets more emancipatory and democratic practices were analyzed. By means of interviews, empirical data related to the first years in the position were collected, which made it possible to glimpse situations of survival/hardships and discovery/delights, according to early career aspects (HUBERMAN, 2013) in three work domains (administrative, pedagogical and political), to raise aspects and specificities of the initial phase of the principals' work, such as the subjectivity of their practices, their difficulties, coping with everyday situations and overcoming difficulties, in a process of permanent training, revealing factors present in the school routine that impact on the learning process of the position, sometimes favoring, sometimes hindering the work of directors: routine activities; the unpredictability of situations; peer support; conflicts and challenges arising from interpersonal relationships; bureaucratic activities and the challenge of pedagogical work aiming at quality education. We conclude that there are numerous difficulties that mark this initial phase of the work of school principals, similarly to teachers, principals also start working in difficult schools, bureaucratic activities and relationships are the most challenging aspects and overcoming difficulties makes with them to remain in the position, leading them to learn how to be principals.

The present work has as its starting point our professional and personal experience, in which we recognize the complexity of the educational process. Each student has an ancestry, a culture, beliefs, religions or absence of faith, different ways of eating, relating, living, being, socializing, which should be present in school. One of the reasons why the different ways of being are not considered is the racism that affects the curriculum and teaching materials. Considering that the studies of the natural sciences are important for us to appropriate knowledge of intra and extra corporeal cycles and natural phenomena, but also to have real conditions to take care of ourselves, to interact with the environment in a healthy, sustainable way, preserving the right to all lives and citizenship for all, we wonder how the textbooks of Natural Sciences/Biology, since it is the science that studies all forms of life, has approached the different manifestations of life, recognizing its diversity and complexity. We have used a racial perspective to analyze three textbooks of Natural Sciences/Biology, used in public high schools in the State of São Paulo. We carried out a literature review on natural science/biology textbooks and the approach to the theme of race; we approach the notion of human race, in the biological, sociological perspective and its resignification by the black movement, as well as the science curriculum and the education of ethnic-racial relations. We rely on authors such as Verrangia (2009, 2010, 2020), Monteiro (2010), Monteiro e Pinheiro (2016), Krasilchik (1987, 2000, 2004) in relation to the teaching of science and the education of ethnic-racial relations; we turn to Maldonado-Torres (2007, 2018), Gomes (2012, 2019) and Gomes e Munanga (2006) on curriculum coloniality and, on being black and the construction of the other as non-being, to Mbembe (2014, 2017, 2018) and Carneiro (2005). With Domingos (2011, 2017), we brought human life from an African cosmovision. For the analysis of textbooks, we performed the description and recording of the observed facts, analysis and ordering (PRODANOV; FREITAS, 2013). Images were selected, by direct identification, of black human lives, human bodies or parts of them. The selection and analysis of the images of human lives present in the Textbooks of Natural Sciences/Biology, showed that only 18% of the images were of black human lives. We emphasize that in addition to the low representation, the images of black human lives were associated, for example, with the study of animals. An image of a black child with the face marked in half was used to exemplify animal symmetry. The analysis of the books revealed the permanence of racism, remnants of colonialism, the appreciation of white human life as a reference standard for human beings and humanity. We conclude that, by placing black human life in a place of invisibility, the analyzed books contribute to the maintenance of epistemic racism. We confirm that the raciality/biopower device acts through the gears of knowledge and power, which still operate as a legacy of colonialism, in the production and social reproduction of education/knowledge, as well as in subjectivities.

The general objective of this research is to characterize the environmental and social dynamics of the Vergel Rural Settlement. In order to reach this objective, we will also go through some specific objectives: to understand the historical and current aspects in relation to the process of occupation and permanence of the settlers; recognize the settlement's relations with the cities of Mogi Mirim and Itapira (country-city relationship) and highlight the main social and environmental themes that permeate the reality of the settlement. The methodological course of the research consisted of the following steps: survey of reports and news; fieldwork; interpretation of geographic information; and collecting testimonies from residents on issues surrounding the settlement. The results showed that what stands out throughout the history of the settlement is agricultural production, mainly subsistence, and the successive attempts to commercialize its products. On the other hand, non-agricultural productions appear as a complement to the income of the families who live there. In short, we consider the relevance of surveying and relating the elements referring to the environmental and cultural dynamics from the spatialization of elements and phenomena through the collection of quantitative and qualitative data that contribute to the planning of the territory from the apprehension of information by the community and by the public power, in the sense of subsidizing decision-making and alternatives for the management of the territory.
