The empirical study was carried out through a survey, using an electronic questionnaire as a data collection instrument, which obtained a sample of 49.3% of the 136 Masters graduated from the Professional Master's Program in Management of Public Organizations and Systems (PPGGOSP) from the Federal University of São Carlos (UFSCar), graduated from 2015 to 2021, addressing the use of the knowledge obtained in the Program and the relationship with their work performance. The PPGGOSP was chosen as the unit of analysis because most students are employees of public institutions, which have their own dynamics for knowledge application and dissemination. After analyzing the research results using the PLS-SEM (Partial Least Square - Structural Modeling Equation) technique, the proposed model was measured and validated, confirming the relationships between Knowledge Conversion and Organizational Learning, and between Perceived Value of Knowledge and Acquisition of Knowledge. Additionally, it was evidenced, through a multigroup analysis, that the relationships between Knowledge Conversion and Organizational Learning, and between Perceived Value of Knowledge and Knowledge Acquisition are greater for employees with less time in the institution and younger age, identifying greater knowledge application, perception of the knowledge conversion impact and organizational learning by people who have worked for less than 10 years in the same institution.

This paper evaluated the resistance to abrasive wear of four types of hard coatings applied by welding to steel used in the sugar and ethanol and mining sectors that can coat defriber hammers, sugarcane chopping knives or loader teeth, in order to increase the service life of the parts and reduce the time of maintenance stops, which optimizes the production system. The coatings evaluated were manganese austenitic (FeMn), FeCrC with high chromium content, FeTiCW containing mixed tungsten-titanium carbide and FeNbC with niobium carbide. The coatings were deposited by the electric arc welding process on a 1020 steel substrate. The characterizations of the coatings were carried out by metallography, energy dispersive spectroscopy (EDS) analysis to identify the chemical elements present in the precipitates formed and Vickers microhardness test. The coatings were submitted to two types of tests to evaluate the abrasive wear resistance of the coatings studied. The fixed ball micro-wear test was performed using 4N, 8N and 12N loads. The rubber wheel test, standardized by ASTM G65:2016, was performed with stops every 10 minutes until completing 30 minutes, and in continuous test of 30 minutes, whose wear resistance was determined volumetric loss by weighing the samples. As a result, the presence of (Fe,Cr)7C3 carbide was observed in the FeTiCW, FeCrC and FeNbC coatings. The hard ternary WTiC carbides formed in the FeTiCW coating adhered and distributed in a martensitic matrix provided the highest hardness among all the coatings studied. The microstructure of the FeNbC coating was characterized by the formation of (Fe,Cr)7C3 carbides adhered to the eutectic matrix (austenite and chromium carbides) with lower hardness than that of the FeCrC coating containing only polygonal (Fe,Cr)7C3 chromium carbides, which are smaller and homogeneously distributed in the eutectic matrix. The FeMn coating showed an austenitic matrix with micropores from the welding process with the lowest hardness among the coatings studied. The results of the fixed ball wear test demonstrated that the 8N load is more severe than the test performed with 12N loads, which due to the large contact load prevents the abrasive from being transported between the sample and the ball. In the rubber wheel wear test, it was observed that the cumulative rate of volumetric loss is maintained with increasing test time, obtaining percentage deviations below 15%. However, the allowable error calculations were below 5%, showing that both tests demonstrate repeatability and reliability above 95%, evidencing that the increase in procedure B time, which is specified in 10 minutes, is ideal, and does not require an increase in test time to evaluate the coatings. In the comparative analysis of the results obtained in the micro wear and rubber wheel test, it was observed that the FeNbC coating was more wear resistant in both tests, followed by the FeCrC coating and FeTiCW coating, with the FeMn coating being the least wear resistant. For the FeMn coating, it was observed that for the fixed ball micro-wear test, increasing the test load provided improvement in wear resistance, evidencing that the mechanical maceration mechanism increases wear resistance as the coating is subjected to the work. It was concluded that higher hardness does not always determine higher wear resistance, since the FeNbC coating with the lowest hardness (569 HV) among the carbide-forming coatings was the most wear resistant, while the FeCrC coating (630 HV) showed higher wear resistance than the FeTiCW coating that has harder WTiC carbides (669 HV), which showed the lowest resistance among the coatings due to the high hardness and brittleness of the carbides, and its wear resistance was higher only than the FeMn coating (261HV).

Studies show that children and adolescents remain among the main victims of domestic violence, which represents failures in preventing and combating violence in the intrafamily context. The expectation of the international scientific community is that this worsens during and after the COVID-19 pandemic period, in view of that spaces considered protective (such as schools) were closed and victims they stay longer with their aggressors as a result of social isolation. It is therefore even more urgent to intensify efforts in the initiatives aimed at protecting these segments. Psychosocial intervention programs aimed at families can collaborate in the fight against violence against children and teenagers, as well as break with aggression and, eventually, minimize the recurrence of cases. However, programs of this nature are scarce and many of them, were not subjected to rigorous processes of scientific evaluation and validation, especially in the Brazilian reality. Based on these findings, the objective of this dissertation was to develop a psychosocial intervention program aimed at families who practiced intra-family violence against children and adolescents. Complementarily, the objective was to evaluate the content of the program, through analysis by expert judges on the subject. Based on the theoretical assumptions of the Cultural-Historical Psychology (PHC), the program took into account the reality of Brazilian families and the social and psychological demands of people assisted in the medium-complexity services of the Unified Social Assistance System. In this way, the program will train professionals (psychologists, social workers and educators) who work at SUAS to intervene with families The dissertation presents a chapter theory on the origin and perpetuation of intrafamily violence from the perspective of PHC. Next, the program is presented in its entirety, including the objectives of each session and the development of each activity. The subsequent chapter refers to the study validity of content conducted from the analysis of 3 expert judges on the subject of intrafamily violence and in psychosocial intervention programs. The evaluation encompassed dimensions about the structure of the intervention, contents, objectives, resources employees, among others. The main results of this study pointed to the need to review the proposed time for the execution of some activities, a adequacy of the language and contents addressed to the reality of the target audience, in addition to a qualification in materials and graphic resources. However, the study also revealed the quality, relevance and potential of the elaborated material, as well as its importance for the instrumentalization of professionals who work in the politics of social assistance. The entire investigative course, which culminated in the positive evaluation of the experts, motivated the continuation of the process of scientific validation of the intervention, which will be subjected to feasibility and effectiveness studies in the future. it is expected that the program developed in this dissertation can be widely disseminated in the contexto two national level and collaborate in strengthening families, so that they are minimized or broken cycles of violence that are perpetuated against children and adolescentes.

Border Gateway Protocol (BGP) is the predominant routing protocol that allows different Autonomous Systems (AS) to communicate on the Internet. Attacks on BGP typically have a significant impact as they can cause unavailability and compromise sensitive data over large geographic areas. Due to the topic’s relevance, several studies were developed that address different research areas on security in BGP. An area of study that stands out is the reproduction of testbeds for detailed protocol analysis. However, a common characteristic of validating the proposals is using a limited representation in scale and fidelity of the Internet structure. This limitation makes it impossible to have a global view of the risk associated with the attacks and identify the mitigation methods. Given this scenario, it became essential to carry out an in-depth analysis of the risks to the BGP protocol at the real and global Internet infrastructure level. This analysis demands solutions representing the real Internet topology and the accurate reproduction of the attack events on real BGP software implementations. This work presents the Minimalistic Security BGP (MiniSecBGP), an emulation-based testbed, and a methodology for risk analysis of interdomain network routing infrastructures. Our solution can use either real or synthetic data about attacks, which allows a better understanding of past attacks to “what-if” scenarios to identify more robust mitigation strategies. The validation tests demonstrated that MiniSecBGP faithfully reproduces real scenarios using topology data and attack events extracted automatically from public datasets or synthetically created by the user.

There is a large amount of text documents available on the web which increases as more devices and users connect to the network. Analyzing and organizing such documents considering characteristics such as subject and keywords becomes an increasingly expensive task, but indispensable, considering tasks such as text mining and information retrieval and, therefore, ways to improve the performance of such tasks are widely investigated. Most tasks aimed at organizing documents available today, such as clustering tasks, focus on only one dimension, that is, clustering only documents considering the occurrence of terms. However, an important aspect of clustering documents is finding topics that identify groups of documents by their content. Two-dimensional clustering strategies, which simultaneously group documents and terms, can be useful in this regard. However, the representation used is, in general, in the form of matrices of high dimensionality and sparsity, which does not include any semantic information. This work presents a new approach to organize documents using co-clustering and the representation of terms in the form of embeddings. The terms of the document collection are clustered in advance, allowing for the reduction of the sparsity and dimensionality of the matrix. In addition to the new representation, the proposed strategy includes contributions to assess the outcome of co-clustering that explore the association between groups of documents and terms. In co-clustering tasks, the results showed that the representation surpasses the traditional TF-IDF representation in specific cases.

The (auto)biographical research in the field of Education associated with the process of teacher education and professional development have been increasingly consolidated in the scientific field. Regarding the link between Mathematics Education and (Auto)biographical Research, it is worth noting that studies guided by the (auto)biographical method have stood out on the national scene, especially in the field of research concerning the teacher who teaches Mathematics (PEM), focus of this study. In this sense, the investigation carried out, of a qualitative nature, aims to investigate aspects related to the teaching learning processes and professional development evidenced by the (auto)biographical narratives of teachers who teach Mathematics. From this objective, we sought to highlight the heuristic and formative role of (auto)biographical sources as material for the study of the trajectories of teacher education who teach Mathematics, exploring the epistemological and methodological principles of (auto)biographical narratives that enhance references and listening to oneself, the lessons learned and the implications of the training trajectories of teachers who teach Mathematics. To answer the central question – which contributions regarding the teaching learning processes and professional development of PEM emerge from (auto)biographical research for the field of Mathematics Education? – a corpus was created with scientific productions related to Mathematics Education and (Auto)biographical Research in the dialogue with the PEM, published in the Brazilian Digital Library of Theses and Dissertations (BDTD), considering the period from 1991 to 2021. In this movement, the analysis of the findings evidenced fundamental contributions of (auto)biographical research to the field of Mathematics Education, with regard to studies focused on the PEM. By highlighting trends and gaps in the production of knowledge, subsidies and paths for new studies are presented, in order to broaden perspectives and meet the demands that arise in the scientific field. It was possible to observe that the (auto)biographical approach has contributed, in the context of Mathematics Education, to the consolidation, conceptualization and characterization of the PEM as an expanding field of research.

Social frailty is the decline in social relationships and social support that are directly linked to the determinants of the life course, which are age, education, income, gender, ethnicity, marital status, residential environment, lifestyle, life events and biological (GOBBENS, ASSEN, 2010). Thus, the need for care becomes a highly relevant factor to people with disabilities. On the other hand, the observed needs require caregivers, mostly informal, mainly family members. The process of caregiving can generate overload to the caregiver and also symptoms of depression. This process can be intensified due to the social changes caused by the COVID-19 pandemic. Thus, the present study aimed to evaluate the social fragility of family caregivers of people with physical and/or intellectual disabilities and its relation with depression in the context of the COVID-19 pandemic. This is a descriptive, correlational, cross-sectional research with a quantitative approach. Thirty-one individuals from a Non-Governmental Organization (NGO), located in the countryside of the State of São Paulo, participated in the research. The instruments Sociodemographic and Economic Characterization, the HALFT scale and the PHQ-2 (Patient Health Questionnaire-2) were applied; Among the results, most were male (56.70%), without a steady partner (61.30%), white (76.70%), with incomplete elementary school education (54.80), 35.5% of the participants self-assessed their health as good. Regarding frailty, 61.5% (n= 19) and 32.0% (n=10) were socially frail and pre frail, respectively. Regarding depression, 35.5% of family caregivers had probable depression. There was strong and statistically significant correlation between HALFT and PHQ-2 (r=0.604; p<0.001). It can be concluded that the level of social fragility and depression of family caregivers of people with Physical and/or Intellectual Disability was high and a strong relationship between social fragility and depression was confirmed.

The hybridization of hollow glass microspheres with short glass fibers in polypropylene can result in low-cost, low-density polymer composites suitable for engineering. Although the addition of fillers in thermoplastic composites generally reduces mechanical strength, recent research indicates that by properly matching high and low aspect ratio fibers, it is possible to achieve desirable mechanical properties, such as stiffness, strength and toughness. In order to broaden the understanding of this mechanical reinforcement mechanism in ternary PP composites with hybrid reinforcement of FV (pretreated with aminosilane) and MEVO, this work evaluated the influence of polymer-reinforcement interfacial interactions on short-term mechanical properties. Three different interfacial compatibilization conditions were analyzed: (i) MEVO pretreated with aminosilane and PP matrix modified with addition of interfacial compatibilizer of PP functionalized with maleic anhydride (PP-g-MAH), (ii) MEVO without treatment and matrix modified with PP-g-MAH and (iii) MEVO without treatment and matrix without compatibilizer. The composites were injection molded with direct mixing of pre-extruded PP/FV and PP/MEVO binary concentrates. Tensile and flexural tests showed a slight increase in the elastic modulus of the ternary composites with higher hybrid reinforcement, regardless of the MEVO content and the interfacial adhesion of the microspheres with the PP matrix. The strength, in turn, strongly depends on the polymer-MEVO interfacial adhesion, presenting a decrease in the mechanical properties without MEVO treatment, even with the presence of the PP-g-MAH compatibilizer. With the pretreatment of MEVO with aminosilane and the use of the compatibilizer, the mechanical properties remained high, comparable to the reference binary composites PP/FV with 25% and 30% FV. The dynamic mechanical analysis (DMA) confirmed the importance of interfacial compatibilization in the mechanical behavior.

Chronic Kidney Disease (CKD) is considered a worldwide public health problem and has a high morbidity and mortality rate. The disease exposes patients to a series of adjustments in their lives and their families, involving socioeconomic, physical, and psychological aspects. The absence from the school or work environment also characterizes the disease as a social problem, and in this way, social support and family functionality boost the well-being and health of patients based on the frequency or quantity of social relationships, performing important functions of an affective, educational, and socialization nature for the individual. The possible absence of this support network, along with dependence in performing activities of daily living, predisposes to possible negative outcomes, such as loneliness and depressive symptoms during the period of hemodialysis treatment. Objective: Verify the level of loneliness and its relationship with socioeconomic and health conditions, social support, family functionality and depressive symptoms in patients undergoing hemodialysis. Method: Analysis of secondary data, with a primary cross-sectional investigation, correlational with a quantitative approach, carried out in 2019, with 80 patients with CKD on hemodialysis. Applied instruments: socio-demographic, economic and health condition characterization, UCLA Loneliness Scale, Medical Outcomes Study Social Support Scale, Patient Health Questionnaire 9 and the Family APGAR. Results: Showed female prevalence (55%), white ethnicity (65%) and mean age 59,63years. In the perception of loneliness, the highest index was (55%), moderately high. Social support scored worst in the Positive Social Interaction domain, mean 74.31. In depression, showed prevalence of severe depression (28.7%). Family functioning showed good score (68.8%). There was a weak negative correlation between loneliness and all domains of Social Support, besides Family Functioning.

In this dissertation, we propose new univariate continuous distributions for modeling asymmetrical data. Initially, starting from a non-linear parametric transformation of an uniform random variable, we propose a new asymmetric one-parameter distribution that extends the uniform distribution, the so-called Lambert-uniform distribution. The transformation is expressed analytically in terms of the principal branch of the Lambert W function in such a way that the inverse transformation is expressed in terms of an exponential function. Consequently, the density function of the Lambert-uniform distribution has a simple closed form and exhibits increasing or decreasing monotonic behavior. Subsequently, based on the Lambert-uniform distribution, we propose a new distribution generator that allows adding one shape parameter to an arbitrary baseline distribution. The added parameter allows a variety of shapes for the density function of the resulting distribution, leading to an expansion of the skewness and kurtosis ranges of the baseline distribution. We observe that the parameter induced by the generator acts as a skewness parameter when the baseline distribution is symmetric. On the other hand, when the baseline distribution has positive support, we observe that the hazard rate function of the resulting distribution corresponds to a modification in the early times of the hazard rate function of the baseline distribution. This is exemplified through the study of four special cases obtained by considering the generalized-bimodal, slash, exponential and Rayleigh distributions as baseline distributions. We discuss the parameter estimation via the maximum likelihood method and evaluate the behavior of the estimators through simulation experiments. Finally, we consider some application examples that illustrate the usefulness of the proposed distributions in different real settings.

The penetration of photovoltaic distributed generation in distribution networks has become a reality; however, it still imposes challenges to be overcome, such as the operation of these networks with minimal deviations in the voltage magnitude profiles. Thus, this work proposes the daily planning of the hourly operation of microgrids in order to minimize the deviation in the voltage magnitude profiles and the minimization of active losses in the distribution through optimal tap ratio adjustments of transformers in substations, optimal adjustments of power banks remotely switched capacitors along the primary feeders and injections of active and reactive power from the photovoltaic generation distributed by smart inverters. In such a Volt/Var Optimization (OVV) problem, the discrete control variables associated with transformer taps and equivalent shunt susceptances of remotely switched capacitor banks are handled by sinusoidal penalty functions that modify the original mixed integer nonlinear programming problem into a nonlinear programming problem with only continuous decision variables. The results obtained for microgrids with 69 and 135 nodes show that the proposed OVV model and its resolution methodology are effective and efficient in reducing the deviation in voltage magnitude profiles, minimizing active losses and, at the same time, reducing of the overall reactive power demand of the distribution network.

The literature demonstrates the use of irradiated semiconductors in the treatment of effluents in a process called heterogeneous photocatalysis, a variant of advanced oxidative processes. The applicability of semiconductors is due to their electronic structure, characterized by bands that, when excited, present charges with redox potential capable of promoting various chemical reactions. TiO2 is the most studied semiconductor oxide for this purpose, however, it is limited by the high rate of recombination of photogenerated charges, which reduces its potential. Another limiting factor is the recovery of the catalyst when it is formed by small particles on the nanometer scale. One way to facilitate the recovery and reuse of the material is by applying them in the form of a film. In this context, using a metallic titanium (Ti) plate in a plasma-assisted electrolytic oxidation (PEO) process allows the formation of a thin layer of its oxide, the semiconductor titanium dioxide (TiO2) on the metal. Also, recent research demonstrates the incorporation of other materials, such as tin dioxide (SnO2), to assist TiO2 during photocatalysis, by forming heterostructures, which act to reduce the rate of recombination of photogenerated charges. Thus, this work aimed to study the applicability of the PEO process in obtaining TiO2 photocatalyst films and the incorporation of SnO2 in the structure by adding it in the form of particulate material to the electrolyte during the PEO process. The application of sulfuric and phosphoric acid in the electrolyte, as well as different concentrations of SnO2 in it, were studied. The characterization of the films was performed using the techniques of atomic force microscopy (AFM), scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS) and X-ray diffractometry. The characterization tests showed the influence of the electrolyte on the crystalline phase obtained, as well as on the surface morphology of the film. The incorporation of SnO2 in the final structure could not be verified, indicating that the concentration used was not sufficient for this purpose. Heterogeneous photocatalysis tests on the degradation of rhodamine B and methylene blue dyes under UV radiation showed the applicability of PEO in obtaining photocatalyst films. The films obtained via PEO showed activity after 4 cycles, indicating the applicability of the process to obtain photocatalyst films with the possibility of recovery and reuse.

The undergraduate medicine course at UFSCar aims at providing generalist, humanist, critical and reflective medical training, based on a differentiated learning model. The active methodology used transforms the graduation scenario, removing students from the comfort zone of traditional learning and creating a fertile ground for clinical reasoning and greater autonomy for the undergraduate. However, it has weaknesses that impact the lives of students and bring greater mental suffering during this learning journey. This Final Paper (FP) will be prepared in accordance with the guidelines of the Pedagogical Political Project (PPP) of the UFSCar Medicine Course. The critical-reflective narrative about my education will be based on the description of the activities proposed by the graduation and my experiences during that period.

This research has as its theme: "Pedagogical Residency Program: Challenges and Potentialities in the mandatory curricular internship and in the initial training of teachers.", aims to analyze the relevance of the Pedagogical Residency Program in the initial training of teachers and to investigate how preceptors (trainers) of the program, look at the potentialities and challenges of the PRP, as a supplementary part of the new policies in the field of teacher education. Contemplating the mandatory curricular internship as an integral part of the program, we seek to collect information through field, bibliographic and documentary research regarding the contributions of the mandatory curricular internship carried out concomitantly with the Pedagogical Residency Program, and how it can contribute to initial training of future teachers. In view of the issues discussed, we seek to relate the relevance of the mandatory curricular internship and the realization of the pedagogical residency as a training policy. As this is a new policy in the field of teacher training, it is opportune to analyze public policies for teacher training, mandatory curricular internship and the teacher training program. Given this content, this work will present a brief political history of teacher training in Brazil, elucidating the issues surrounding teacher training, from the mandatory curricular internship, the emergence of the Pedagogical Residency Program, school-university partnership and initial teaching performance

The spectroscopy methods of analysis, as Mid Infrared (MIR) and Raman spectroscopy, are based on the interaction of light and matter. These techniques present advantages, such as, non-destructive analysis, low cost and little or no sample preparation. However, in the analysis of complex matrices (food, beverages, and drugs), interferents agents decrease the capacity of these techniques, especially in detecting of minority compounds. In this way, the modification of these matrices in order to reduce the interferences, presents itself as a viable alternative, expanding the analysis capacity and enabling new applications of such techniques. In this work, it was performed the modification of matrices in three different applications for analyses using MIR and Raman spectroscopy. The aim of carrying out the treatment of samples before the analysis aimed to overcome limitations of analytical techniques related to direct analysis, such as fluorescence in Raman and water interference in mid-infrared. In the first application, it was proposed the quantitative determination and stability study of acetylsalicylic acid (ASA) in commercial samples by Raman spectroscopy and univariate analysis. For this purpose, four solution of 3% m/v AAS at pH values varying from 6 to 12 were prepared. Raman spectra were collected at intervals of 30 min in the first two hours of analysis and 1 h of interval after two hours, in a total of 8 hours. For quantitative determination, a concentration calibration curve in the range of 1 to 5% m/v of AAS, was built. After evaluating of stability, two commercial drugs containing AAS were purchased in the local market and the content of the active ingredient was determined. The values found by Raman Spectroscopy were compared with the results obtained by the standard method (HPLC) and presented relative deviation below 1%. In the second application, a sample opening method was proposed using liquid-liquid partition with ethyl acetate to analyze by FTIR-ATR 11 brands of Pilsner beers, divided into the Standard American Lager and Premium American Lager categories. The data were pre-processed the exploratory study performed using Principal Component Analysis (PCA). According to the results, spectral patterns (fingerprints) of the compounds present in the organic extract of the analyzed samples were obtained. It was possible to verify that FTIR-ATR technique was able to separate the analyzed beer brands in distinct groups. Moreover, the FTIR-ATR was able to separate samples of different brands according to the production location. Finally, in the third application the quantitative analysis of ethanol in beer, wine and whiskey samples was performed by Raman Spectroscopy. As a strategy to reduce interferents, the modification of the matrices with sodium hypochlorite was carried out. This method has as its main objective to suppress the fluorescence of samples, caused by the components present in these matrices. The results showed that the use of sodium hypochlorite was effective in the suppressing of fluorescence, allowing for the quantitative analysis of ethanol in the analyzed matrices. The relative deviation between Raman Spectroscopy and the reference method (Gas Chromatography - GC) was below10%.

The general objective of this work is to unveil knowledge of teaching in Higher Education, from the mapping of academic productions that dialogue with (auto)biographical narratives. For the composition of the corpus of analysis of this work, we used, as a database, the Revista Brasileira de Pesquisa (Auto)Biográfica (RBPAB). The time frame adopted considers the period from 2016 to 2021, marked by the beginning of the publication of the Brazilian Journal of (Auto)Biographic Research, culminating in the year this research was carried out until the month of November, considering the last published volume (v18). The theoretical framework adopted considers the academic production of different authors who focus their research on teaching knowledge in Higher Education, the construction of identity and teaching professionalism, research through (auto)biographical narratives in Education, among others. For the construction and development of this study, the quantitative-qualitative methodology was chosen, considering the realization of a Systematic Mapping of the academic production inherent to the aforementioned period, as well as the contributions of Falbo, Souza and Felizardo (2017) and Vosgerau and Romanowski (2014), composition of the analysis corpus and production of results. Twenty-six articles published by RBPAB were analyzed. The mapping of academic productions was made from the reading and recording of these works, among which four thematic axes emerged, organized in order to unveil the teaching knowledge in Higher Education, which used (auto)biographical narratives. The academic productions analyzed show that the teachers' memories of their trajectories influenced the generation of important knowledge for their professional training, as the images they had about what it was to be a teacher were related to representations that were being (de)constructed and (re)constructed from self-writing, from reflections on their formative processes, as well as from their professional trajectories and life stories. The narratives about life histories considered as a training device brought us a perspective of the teaching profession as practiced by a human being who needs to be considered as beyond a technically constituted professional, that is, as a person who is, in its entirety. Through this device, the (trans)formation of themselves and their teaching practices occur progressively, while they build and expand their knowledge through their (auto)biographies, as these provide them with opportunities for self-knowledge, self-training and a new way of seeing and living teaching in Higher Education.

In the daily routine of the regular classroom, teachers and educational interpreters need to organize specific aspects and solve demands related to the teaching of deaf students. Although they work together, these professionals usually do not have moments outside class hours to share experiences and reflect on their actions. Recognizing the importance of this process for the quality of teaching-learning of deaf students, we proposed the creation of a shared formative space between teachers and educational interpreters in service in a public school in the interior of São Paulo. We aimed to investigate the potential of this space for Bilingual Education of the Deaf, focusing on the moments of instruction, analyzing possibilities of the proposal, difficulties of implementation, gaps and potentials found in the educational practices of these professionals, in order to expand their experiences and reflections on the teaching process for this public in the classroom. To this end, we mobilized the cultural-historical theory proposed by Vygotsky and other authors, studies in the field of Deaf Education and studies on training aspects of teachers and educational interpreters. Focusing on the training process, we followed three pairs (teacher-interpreters) during one school year in the school where the project was developed. We recorded the meetings on video and audio (most of them) and collected the data to be analyzed by transcribing the speeches of the participants. The actions implemented in the training space consisted of dialogues with the pairs, during which we addressed specific issues related to deafness, methodological aspects of teaching deaf students, different possibilities of interpretation in Libras, forms of support for teaching practice and practices of the educational interpreter, in order to promote joint reflections on new possibilities of educational actions. From the analysis of the dynamics of the meetings, three cores of meaning emerged: Pedagogical practices, Organizational processes and Formative processes. As a main result of the analysis, we highlight the expansion of the dialogue between professionals for shared decision making, which enabled the creation of new strategies for the teaching of deaf students, in a more conscious way. The teachers and educational interpreters benefited from these common moments of organization, overcoming difficulties by jointly executing the planning with the external view of a professional trained to generate, discuss and forward reflections on other forms and possibilities of actions. We could see, therefore, that the establishment of this partnership in the training meetings leads professionals to a better work both for deaf students and for the school as a whole. However, it is a process full of challenges, permeated by dynamics of institutional functioning and important aspects that must be appreciated in order to promote, in fact, a quality Bilingual Education for the Deaf.

Indigenous peoples have the right to specific, differentiated, intercultural, bilingual/multilingual and community education, guaranteed by law. Like all the rights of indigenous peoples, school education was the result of several struggles and the union of different indigenous and indigenist movements. And in the same way that school education took time to have legal support and to take its own form, detached from its historical burden, Special Education is gradually being seen with different eyes by the indigenous themselves. Therefore, showing the interface of Special Education in Indigenous Schools is of paramount relevance. This research sought to answer some questions: Are indigenous students who are the target audience of Special Education (PAEE) being served at the indigenous school? What actions are developed to assist PAEE indigenous students? And how are these actions being developed by teachers and school managers? Thus, this work had as general objective to know the interface of Special Education in a Terena indigenous school. With the specific objectives of investigating whether there is service for indigenous PAEE students and how this service takes place; to describe what are the actions developed to assist the PAEE indigenous students and how these actions are being developed by teachers and managers of the school that is the focus of this work. It is a qualitative approach work. To obtain data, structured questionnaires were applied individually by the researcher. The questionnaires were prepared by researchers specialized in the field of Special Education, from the Federal University of São Carlos, through which we were able to characterize: the respondent, the school's data, the access and permanence of the PAEE student in the school, the school's infrastructure, administrative and pedagogical actions and the participants' sense of self-efficacy, etc. This work portrays the interface of special education in a Terena indigenous school in the municipality of Anastásio, in the state of Mato Grosso do Sul. We can conclude that the service to the Terena indigenous of this municipality has taken place and that the managers and professionals working in the school have sought to meet the demands of their public.

Let G be a compact Lie group and X be a finitistic space. If G acts continuously on X, we can construct the fibration X \hookrightarrow X_{G} \arrow & B_{G}, (1) called Borel fibration, where G\hookrightarrow E_{G}\to B_{G} denotes the universal G-bundle and X_{G} is the orbit space (E_{G}\times X)/G, also known as the Borel space. When the action on G on X is free, there is a homotopy equivalence between the orbit space X/G and the space X_{G}. Therefore, we can use the Leray-Serre spectral sequence {E_{r}^{\ast,\ast},d_{r}}, associated to the fibration (1), which converges to the cohomology of the total space X_{G}, to get the cohomology ring of the orbit space X/G. In this thesis, we use these tools to investigate the existence of free actions of the compact Lie groups Z_2, S^1 and S^3 on some finitistic spaces. Precisely, we study the existence of free action on finitistic spaces with mod 2 cohomology of a Dold manifold P(m,n), a Wall manifold Q(m,n), a Milnor manifold H(m,n), a product of spheres, the (real, complex or quaternionic) projective spaces and spaces of type (a,b). When the space X admit such such structure, we compute the mod 2 cohomology of the respective orbit space X/G.
