Deep Learning Inversion (DLI) has emerged as a promising and computationally efficient alternative to traditional seismic inversion. However, its practical adoption is limited by the scarcity of large and diverse training datasets. Existing research in DLI has primarily emphasized the design of novel network architectures, while largely overlooking the potential of data-centric training strategies. This dissertation addresses this gap by systematically evaluating the effectiveness of synthetic data strategies for enhancing DLI workflows. We first establish the fundamental capabilities of data synthesis, demonstrating the generation of high-fidelity velocity models using Denoising Diffusion Probabilistic Models and exploring semantically controllable geological feature engineering through Variational Autoencoders. Building on these foundations, we conduct a comprehensive comparative study that empirically assesses the impact of a spectrum of data augmentation techniques (ranging from simple interpolation to advanced generative diffusion) across multiple DLI architectures. The results show that data augmentation consistently improves performance, while also revealing that more complex strategies do not always outperform simpler ones. Importantly, the choice of augmentation method is closely tied to the underlying model architecture, highlighting a critical cost-benefit trade-off in data strategy design. The practical relevance of this research is further demonstrated through the development of a state-of-the-art DLI solution that leveraged a massive-scale synthetic dataset to secure a top 1% ranking in an international seismic inversion competition. This dissertation contributes to advancing data-centric approaches for seismic inversion, underscoring that the strategic use of synthetic data is essential to fully unlock the potential of DLI.

In order to formulate its basic hypothesis, this research starts from the following question: does Barsa Livros, an independent bookstore, present itself as an element of friction [rugosidade] within the dynamics of vertical and horizontal relationships of the social organization? Barsa Livros is an independent bookstore in Ribeirão Preto, state of São Paulo, Brazil. It began its activities in 2020, initially operating digitally and with a sales system based on orders. As it developed, it adopted a hybrid approach: dealing with printed books and building its inventory; participating in fairs held in various cultural spaces; and, subsequently, also establishing a physical location, where its activities now take place and where its entire collection is housed. Through a case study, we propose to analyze the publishing market – notably the bookselling sector – in its current historical particularity, with the presence of digital technology and the power exerted by the use of information, presented within the empirical framework of John B. Thompson (2021) and through Bourdieu's (2018) field theory, in order to define the publishing and bookselling field and position the studied bookstore within it. Furthermore, in light of José De Souza Muniz Júnior's thesis (2016), we will study the position of "independent" within this publishing field, as well as the polysemy of the term and its possible characteristics in order to understand the possibility of Barsa Livros presenting itself as an independent bookstore in this field. Subsequently, using Milton Santos' geographical theory (2023), the dynamics of verticalities and horizontalities that compose the banal space will be analyzed in order to verify whether Barsa Livros presents itself as an element of friction within it. Finally, we will test the hypothesis that this bookstore functions as a medium and materializes this friction in space through the methodology of materialized organization and organized matter (OM/MO) as seen in Régis Debray (2000), in addition to analyzing the bookstore's collection as a technema: a technique that makes it point to reticular and/or contiguous organizations, as well as, in its double-body, relate to hegemonic and/or popular sensibilities (Santos, 2022).

This Final Course Assignment Thesis is part of the requirements set forth in the Pedagogical Program of the Medical graduation at the Federal University of São Carlos (UFSCar). It takes the form of a critical and reflective narrative about my personal journey - especially the academic one - throughout the past six years, primarily about my dedication to medical training. Although this is an academic assignment, reflecting on my experience as a medical student cannot be separated from the broader context of my life. After all, medicine is a profession rooted in caring for others, and both the person I am and the professional I am becoming are inseparable from the experiences and learning that have shaped me. This narrative is structured chronologically, starting with my entry into medical school, and is contextualized within the reality I lived at that time. It follows the academic progression through the three curricular cycles of the UFSCar Medical Program, with emphasis on the specificities of the course and how they resonated with my own way of learning, seeing and engaging with the world. Throughout, I critically reflect on each personal stage of this six-year journey, from 2020 to 2025, drawing connections between personal growth and professional development. The final section of this work addresses my current perspective on Medicine and the way I hope to practice it. It also touches on my expectations for life beyond the University and how I still believe there is space for emotion within professional life. I view as outdated the notion that Medicine must be purely rational, devoid of feeling. I’ve come to understand that empathy - an essential component of care - cannot exist without personal emotions. At the same time, I recognize the importance of practicing evidence-based Medicine, while striving to balance it with what I describe as “listening with the heart”. I am fully aware that this balance is not easily achieved; it is a continuous, intentional effort that requires continuous commitment. Caring for others also depends on caring for myself. Both are essential for providing meaningful, compassionate care. In the end, the very title of this work itself offers a fair summary of everything it represents.

Introduction: Studies conducted in recent years have associated pulmonary auscultation and imaging patterns with the etiology of SARS-CoV-2 in patients with pneumonia. However, there is a need for studies to confirm and validate such diagnostic accuracy. Improving diagnostic suspicion with medical propaedeutics combined with imaging tests can bring clinical benefits in cases of difficulty in accessing the etiological diagnosis and even in the event of the advent of new strains that may be less detectable. Objective: This study seeks to associate the clinical and radiological propaedeutics of patients hospitalized with SARS with the etiological diagnosis, focusing on COVID-19. Materials and Methods: A cross-sectional observational study comparing pulmonary auscultation and radiological patterns on chest computed tomography (exposure factor) with the diagnosis of COVID-19 (outcome). To this end, the medical records of adult patients (≥ 18 years) hospitalized with SARS for at least 24 hours at the UFSCar University Hospital in 2020 were reviewed, with a confirmed or excluded diagnosis of COVID-19 by RT- PCR, with plain chest radiography or chest computed tomography in the 72 hours before or after admission. Pulmonary propaedeutics, radiographic and tomographic images were evaluated according to forms developed in the Redcap program. The calculated sample consisted of 42 clinical evaluations, 52 chest radiographs, and 96 tomographies. Patients were matched 1:1 by sex, date of admission, and age. Radiological images were analyzed by two evaluators. Results and conclusion: A total of 122 patients were included, with no significant differences between COVID-19 and non-COVID-19 patients in terms of pulmonary auscultation. Chest radiography was performed with the appropriate technique in only 53.8% of cases. The characteristics of plain chest radiography most associated with SARS-CoV-2 etiology were the presence of micronodules, involvement of the lower lateral region, and greater intensity of opacities. Chest computed tomography showed greater discrimination of etiological diagnosis in adult patients with SARS, with crazy paving opacities associated with COVID-19 and the finding of septal thickening not accompanied by ground glass and mediastinal adenomegaly associated with other etiologies. There was low agreement in the assessment of lung fields on plain chest radiography, which was better for assessing the mediastinum and costophrenic sinuses. There was moderate agreement in the assessment of tomographic images regarding the nature and distribution of lesions and the suspected etiological diagnosis.

This work presents a critical reflection on the journey of medical education, based on the author's personal experience. It aims to highlight the contrast between the initial idealizations of the medical profession and the practical realities of clinical work. Throughout the course, the student is faced with the daily routine of medical practice, which proves to be far from the collective imagination of heroism and social prestige. Medicine is understood as a continuous, demanding, technical, and human-centered activity that requires constant learning, emotional balance, empathy, and adaptability. The importance of understanding the patient as a unique individual is emphasized, recognizing that the experience of illness goes beyond pathophysiology and includes social, emotional, and contextual aspects. The text addresses the vulnerability of the Brazilian healthcare system, social inequalities, and the social determinants of the health-disease process. The academic experience during this period allowed the author to observe how factors such as housing, income, and access to information directly impact illness and healthcare. The persistent lack of health education is also discussed as a major challenge, making it difficult to promote healthy habits and patient autonomy. The role of the physician is highlighted as that of a guide, caregiver, and agent of change, even in the face of resistance. Extracurricular experiences in basic research and data analysis contributed to the author’s critical and scientific development, reinforcing the understanding of medicine as a technical, social, and investigative field. It is concluded that medical practice must be grounded in listening, science, and ethical responsibility, as a daily task of action, reflection, and constant improvement.

This work presents a reflective account of the author’s personal experience as a hospitalized patient in 2020, immediately before entering the Medicine course at the Federal University of São Carlos. The hospitalization occurred due to a ruptured ovarian ectopic pregnancy, requiring exploratory laparotomy and oophoroplasty, followed by care in the intensive care unit and general ward at the Centro Hospitalar Municipal Dr. Newton da Costa Brandão, located in Santo André, São Paulo. The account explores how experiencing a traumatic event and undergoing hospitalization impacted the author’s academic development and perception of life and the doctor-patient relationship. The reflection articulates concepts of life and death from both scientific and existential perspectives, integrating personal experience with the six years of medical training. This experience highlights how being “on the other side of the bedside” contributed to the development of humanistic competencies, empathy, and understanding of patient suffering and vulnerability. This work aims to demonstrate that experiences of illness can significantly influence the academic trajectory and professional development of medical students, reinforcing critical reflection on clinical practice.

This Final Coursework consists of an experience report in a narrative format about the six-year journey through undergraduate medical training at the Federal University of São Carlos (UFSCar) between 2020 and 2025. The objective is to analyze the difficulties, learnings, and transformations that shaped the construction of my professional identity. The trajectory is initially marked by the impact of the COVID-19 pandemic, which imposed a distance learning model for the first two years. This phase generated frustration due to the absence of practical activities, insecurity with clinical skills, and the need to develop resilience and proactivity. The return to in-person learning from the third year onward represented a "turning point," allowing for the rediscovery of the passion for medical practice, despite the reality shock of dealing with the complexity of real patients. The fourth year was a period of consolidating confidence and maturing clinical reasoning, with the development of the concept of "longitudinal care". The internship (fifth and sixth years) is described as a "culture shock" between hospital medicine and primary care, and as the period of definitive discovery of the vocation for Internal Medicine, motivated by the intellectual challenge of complex cases. Extracurricular activities are presented as a strategic tool that evolved from online exploration to immersive internships that solidified the choice of the future specialty. It is concluded that, despite its flaws and challenges, the training was paradoxically effective in forging a resilient professional with a profound clarity about his path in medicine.

In Brazil, many unplanned pregnancies occur during the postpartum period, causing harmful consequences for women, children, and families. The use of an appropriate contraceptive method in this group aims to mitigate this unfavorable situation. In this sense, long-acting contraceptive methods (LARC) appear to be quite satisfactory options due to their specific characteristics, especially the etonogestrel subdermal implant. This study aims to evaluate the experiences of vulnerable postpartum women using the etonogestrel implant in a city in the interior of the state of São Paulo. The study has an observational, cross-sectional, descriptive/quantitative profile of postpartum women who have been using this method for at least three months. The survey revealed that the social profile of most participants was between 17 and 19 years old (24.1%), mixed race (41.4%), high school graduates (31%), and the majority were single (51.7%), and evangelical (27.6%). Regarding parity, the vast majority of women already had at least one child (93.1%). Regarding vulnerability, the most common conditions were alcohol and/or drug use (28%), adolescents with children (24%), and mental and cognitive disorders (20%). Regarding previous contraceptive methods, we found that more than half of the women were already using some form of contraception before implants (51.7%), with the main choices being oral contraceptives and male condoms. Breastfeeding was also common among study participants (82.7%), with the duration ranging from 1 month to 2 years and 4 months. The implant was considered satisfactory by most participants (55.2%), with efficacy (65.5%) and convenience (34.4%) being the main positive aspects reported. Regarding bleeding patterns, 41.3% reported patterns considered favorable (infrequent/regular/amenorrhea). Although frequent and prolonged bleeding was the main complaint (55.1%), and prolonged bleeding predominated between 6 and 24 months, with a tendency to improve after this period, 75% of users were satisfied with their bleeding pattern, and almost half (48.2%) considered the reduction in menstrual flow positive. The data obtained allow us to conclude that there is a trend toward a high level of overall satisfaction among users of the etonogestrel implant, reinforcing its efficacy, convenience, and suitability, especially in vulnerable settings.

The limitations of throughput remain one of the main challenges for mobile network performance. They stem from factors such as capacity constraints, coexistence of multiple technological generations, user mobility, massive integration of the Internet of Things, and unequal access in regions such as Latin America. This variability directly compromises Quality of Service (QoS) and Quality of Experience (QoE), highlighting the need for predictive mechanisms capable of anticipating performance fluctuations, optimizing radio resource allocation, and ensuring efficient connectivity in heterogeneous and complex scenarios. In this context, accurate throughput forecasting plays a central role in adaptive resource management and in maintaining service quality in mobile networks, especially under high-mobility conditions. This work systematically investigates two fundamental dimensions of time series modeling applied to this problem: (i) the contrast between local and global models, and (ii) the impact of including or excluding external covariates. To this end, statistical, machine learning, and deep learning methods are evaluated using real-world mobile network data, where throughput is predicted from channel quality metrics and user speed as potential covariates. Experimental results show that global tree-based models, such as LightGBM, provide the best balance between accuracy, robustness, and efficiency. Furthermore, the use of covariates—mainly related to network quality—proved insufficient to consistently improve predictive performance given the inherent complexity of the forecasting task.
Planejamento da paisagem à conectividade entre Unidades de Conservação: estudo de caso na Bacia Hidrográfica do Sorocaba e Médio Tietê

This study analyzed the ecological connectivity among Protected Areas (PAs) in the Sorocaba and Middle Tietê River Basin (UGRHI-10), a region marked by intense urbanization, forest fragmentation, and anthropogenic pressures. The objective was to identify ecological corridors to support landscape planning and guide compensation and forest restoration strategies. To this end, three target species from the Columbidae family were selected, representing different degrees of forest dependence (Geotrygon montana, Leptotila verreauxi, and Patagioenas picazuro), used as models for defining the landscape resistance matrix. The methodology involved an integrated analysis of land cover and land use, PA zoning, interviews with managers, construction of resistance matrices with expert consultation, and modeling of least-cost paths using Linkage Mapper software. The generated routes (i.e., ecological corridors) were spatialized and overlaid with municipal boundaries, and Kernel density analyses were applied to identify connectivity hotspots. In addition, data on the reduction and deficit of Permanent Preservation Areas (PPAs) and Legal Reserves (LRs) were incorporated, enabling the definition of priority areas for environmental compensation. The results revealed a landscape dominated by agriculture (40.17%) and pastures (24.03%), with only 20.38% of forest remnants. Sorocaba stands out as the main urban center and a hub of anthropogenic pressure, while municipalities such as Ibiúna, Piedade, and Bofete hold the largest remnants of native vegetation. The analysis indicated that potential corridors are concentrated in the southeastern and northwestern regions of the basin, connecting larger forest blocks and strategic PAs, although urban and agricultural barriers limit overall landscape permeability. The integration of connectivity routes with environmental deficits highlighted Anhembi, Bofete, Botucatu, Conchas, Itu, Porto Feliz and Tietê as priority municipalities for compensation, guiding restoration actions toward the landscape’s connectivity needs. It is concluded that landscape planning at the regional scale, based on target species and spatial analysis of the resistance matrix, is an effective tool to inform public policies and forest compensation processes. The proposed approach contributes to strengthening ecological connectivity, supporting biodiversity conservation, and promoting greater environmental resilience in the face of anthropogenic pressures and land-use changes in the basin.

This decolonial study seeks to break historical silences and question the notion of a universal knowledge. By confronting the coloniality of knowledge, particularly the myth of scientific neutrality, I acknowledge my own non-neutrality and adopt writing in both the first-person singular and plural. The use of the plural expresses the voices of a collective of adolescents who participated in the investigation as researchers, recognizing them as protagonists of their life processes and the topics that concern them. This choice responds to the need to overcome adult-centered and exclusionary perspectives that have historically marked the production of knowledge about this population. Furthermore, despite advances in the field of child and adolescent mental health, there is still a need to expand knowledge production focused on adolescents, in order to support the design and implementation of effective mental health promotion strategies that recognize their singularities, given the increasing experiences of suffering among adolescents. The sense of belonging has been highlighted as an important element in this debate, as it directly influences adolescents’ mental health. Objectives: To explore, identify, and analyse adolescents’ perspectives on the sense of belonging, examining its relationship with the different contexts in which they are embedded and with mental health. Methodology: The theoretical-methodological framework that underpins this investigation is participatory research, characterized by its commitment to occur democratically and horizontally, and to be conducted WITH the subjects rather than ON them, which already implies a potential for transforming reality. The study took place in a community space located in a socially vulnerable territory. Seven adolescents participated, and their engagement was fostered through creative methodologies and methodological coexistence, also supported by my professional perspective as an occupational therapist and by the principles of Popular Health Education. To produce the data, we used various resources, including poster and mural construction, field trips inside and outside the territory, model-making, photography, and interviews, which stimulated group discussions. I also used field diary records written by myself. Data analysis was conducted collectively and integrated into the production process itself. Results: Data were constructed throughout the process and are organized into three axes. In the first, I describe how adolescents’ participation in the research was constituted. As the research group consolidated, the sense of belonging to the collective also strengthened. This belonging, present from the beginning, acted as a driving force for participation: the more it expanded, the more significant adolescents’ engagement in the investigative process became. In the second axis, I present data emerging from the experience of sharing daily life with adolescents, highlighting how they experienced the community space. We observed that the sense of belonging is reinforced when there are opportunities to play, share food, and move freely. In the final axis, I describe activities developed at a stage of the research when adolescents already had a more solid participation repertoire and demonstrated greater proactivity, showing how “belonging-being” (“perten-ser”) enhances participation/action (“particip-ação”). From these activities, we produced data revealing adolescents’ appreciation for experiences of community and solidarity experiences, the complexities and difficulties of social relationships among them, and the school as a space perceived as one of exclusion and non-belonging, while also providing adolescents’ suggestions to transform this school reality. Discussion: Initially, I propose a reflection that highlights the sense of belonging as an analytical key to understanding adolescent participation. Then, I emphasize that “belonging-being” seems to be related to the strengthening of bonds, connecting to concrete possibilities of access and rights guarantees. I also discuss belonging in light of social markers and intersectionalities, emphasizing that “belonging-being” in contexts of social inequality and exposure to different forms of prejudice and violence constitutes an act of resistance. Finally, I address my role as a researcher and occupational therapist, reflecting on the contributions of the field to conducting participatory research.

This thesis investigates the upcycling of orange juice waste biomass into aerogels and cryogels, and their performance as organic carriers of phase-change materials (PCMs). PCMs can store and release thermal energy at nearly constant temperatures during phase transitions, typically solid–liquid, which makes them suitable for passive temperature regulation applications. Aqueous suspensions were prepared by subjecting the whole and fractionated biomass waste (namely peels, pulp, and bagasse) to a citric acid pre-treatment, which promoted the extraction and solubilization of pectin into the liquid phase, and the swelling and fibrillation of the insoluble fraction. The kinetic stability of suspensions was tuned by adjusting preparation parameters (e.g., washing or non-washing, biomass and citric acid contents), enabling the production of homogeneous 3D porous materials using different processing routes. Aerogels were prepared via non-solvent-induced phase separation (with ethanol or acetone) followed by drying with supercritical carbon dioxide, and cryogels via suspension freezing followed by lyophilization. Aerogel beads were also produced by dripping the biomass suspension in ethanol prior to supercritical drying. Porous materials with varied morphologies, textural and mechanical properties, thermal conductivities and biodegradation rates in seawater were obtained. Two organic PCMs, polyethylene glycol and coconut oil, were loaded into obtained porous materials via vacuum-assisted melt impregnation for dimensional stabilization. The resulting phase-change composites were characterized for their thermal behavior and leakage resistance above the PCMs melting temperature, showing that the porous materials’ morphology and compatibility with the PCMs had a decisive impact on their performance as carriers for PCMs.

A reflective narrative about a unique academic journey marked by the integration of prior knowledge from school during medical school, facing challenges such as a suspension of enrollment, the COVID-19 pandemic, and the struggle with depression during her six years of undergraduate studies. Upon entering medical school with a constructivist methodology, she needed to integrate her prior knowledge and use adverse experiences as catalysts for her personal and professional growth. The constructivist approach to medicine led to effective learning and guided her toward a patient-centered practice, recognizing the importance of individuality and fostering empathy and respect in clinical relationships. Completing this training not Only provides her with a medical degree, but also ethical and compassionate medical practice. A journey that reflects the ability to transform challenges into driving forces for building a unique medical education.

Software systems must continually evolve to remain useful, but this evolution often increases complexity and degrades quality, making refactoring essential for long-term maintainability. Despite significant research on automated refactoring recommendations, existing approaches remain limited: the vast majority focus on solving specific problems like code smells or rely on software metrics, while neglecting the rich semantic and syntactic representations of source code. Moreover, they usually provide partial support, such as identifying where to refactor without specifying what refactoring to apply or suggesting a refactoring type without clarifying its rationale. This narrow scope not only overlooks diverse and real refactoring needs but also undermines developer trust, reducing the practical usefulness of such tools. This work addresses these limitations by proposing an artificial intelligence–based approach for generating complete recommendations for Extract Method refactoring. Grounded in real refactorings applied in the past of the projects and leveraging the semantic representation of code, the approach delivers recommendations that explicitly cover the W3B criteria, developed in this work: Which refactoring to apply, Where in the code it should be applied, Why it is suggested, and the Benefits it brings. The methodology followed a multi-phase pipeline. First, a specialized dataset of Extract Method samples was systematically built. Second, a recommendation model was developed by fine-tuning CodeBERT to measure the affinity between candidate fragments and the analyzed method. Third, a consensus-based explainer was designed, aggregating outputs from SHAP, LIME, and ANCHOR with a Random Forest surrogate to provide interpretable explanations. Finally, the outputs of all phases were integrated into a concluding phase, completing the proposed approach and delivering complete and interpretable Extract Method recommendations. Evaluation was conducted through a controlled experiment with postgraduate students (7 participants out of 9 initially enrolled), who provided a total of 24 evaluations by assessing more than one method each. Results showed a statistically significant improvement in participants’ confidence scores (p = 0.011), strong alignment between tool suggestions and participants’ own choices (57.7%), and high agreement (96%) with the stated benefits, including readability, modularity, and maintainability.

This thesis aims to investigate the conceptions of the human being expressed by Philosophy teachers working in public high schools in the state of São Paulo, Sorocaba, Brazil . Based on the premise that an educator’s understanding of the human being directly influences their teaching practice and educational vision, the research sought to comprehend how these conceptions manifest in everyday school life and what contributions they offer toward a more humanizing education. Ten teachers from different schools across the state were interviewed to capture their philosophical, pedagogical, and existential perceptions about human nature, its potentialities, and challenges in the contemporary context. The theoretical framework is primarily grounded in the philosophical anthropology of Max Scheler and the existential personalism of Viktor Frankl, in addition to contributions from other classical and modern thinkers such as Plato, Marx, Descartes, Heraclitus, Hegel, and Aristotle, among others. The research integrates these references with the teachers' narratives, demonstrating how different philosophical traditions still influence contemporary pedagogical thinking. The methodological approach was qualitative, with a phenomenological and constructivist emphasis, aiming to understand the teachers' experiences based on their concrete realities, educational paths, and theoretical foundations. The analysis values the teachers’ narratives as legitimate sources of knowledge production about the human being and the role of Philosophy in schools. The findings reveal a plurality of conceptions of the human being among the interviewed teachers, reflecting influences from a wide range of philosophical perspectives — from Cartesian rationalism to Heraclitean becoming, from historical materialism to existentialist transcendence. Despite the challenges faced in their school contexts — such as the devaluation of Philosophy, limited class hours, and a rigid curriculum structure — these teachers demonstrate a strong commitment to the ethical, critical, and reflective formation of their students. Their testimonies reflect an active resistance to the dehumanization imposed by contemporary social, political, and educational crises, reaffirming Philosophy as a fundamental tool for fostering awareness, empathy, and human dignity. The research concludes that the teaching of Philosophy, when grounded in a conception of the human being attentive to historicity, freedom, culture, and spirituality, has the potential to contribute to an emancipatory education and the construction of a more just, supportive, and humanized society. This study thus hopes to provide theoretical and practical support for strengthening the role of Philosophy in basic education and for recognizing the Philosophy teacher as a key agent of social transformation and a builder of consciousness.

This Undergraduate Thesis presents a longitudinal reflective narrative on the author’s experience throughout the six-year medical course at the Federal University of São Carlos, addressing both professional and personal development. The work traces the trajectory from moments prior to entering the university to the approach of graduation, in a narrative, critical, and subjective manner. It explores aspects such as entering the course during the COVID-19 pandemic, adapting to a new learning methodology, early involvement in patient care and assistance, and the choices and expectations that emerge near the end of the program. Throughout the narrative, the author engages in a reflective dialogue on anxiety, one of the most prominent feelings during the course. The thesis presents reflections on the challenges of anxiety within the program and the ways students cope with it. Additionally, the author discusses anxiety as something imagined to guide the formation of personality, but which, in practice, proved to be more of an obstacle than a support, creating a point of rupture regarding this ideal.

This study addresses the issue of knowledge production regarding the schooling of students with Autism Spectrum Disorder (ASD) during the COVID-19 pandemic (2020-2023). The objective is to understand the obstacles the COVID-19 pandemic created in this schooling process, investigating the main difficulties faced in the school context, their repercussions on pedagogical practices, and the possibilities for transformation and learning that emerged in this scenario. This is a qualitative bibliographic research study, in which the BDTD and CAPES databases were used for analysis, with the following descriptors: "schooling ASD pandemic" and "schooling autism pandemic." It should be emphasized that only the abstracts of the papers were read due to lack of time for a complete reading. A total of 39 papers were found, 22 in the BDTD database and 17 in CAPES. However, 10 of these were repeated across the databases, with only one occurrence of each being considered to avoid duplication, totaling 29 verified works. It is clear that the majority of the works are dissertations. Furthermore, 27 works were produced at public universities, demonstrating the need to defend free, high-quality public education. The Southeast region produced the most works due to the country's largest concentration of universities. The specific topics addressed were: teacher training, life history and school trajectory, pedagogical practices, teaching-learning processes, and technologies, with a greater emphasis on pedagogical practices, that is, how teachers and education professionals dealt with the COVID-19 pandemic. Regarding the level of education, most works did not specify the level studied, but early childhood education and more than one level were highlighted. The same occurred with the theoretical basis: 20 works did not specify their bases; those that did were divided between the historical-cultural aspects of human development and Freirean pedagogy. Regarding methodological approaches: 15 studies did not specify their approaches; among those that did, qualitative approaches, which are common in education, stood out. Regarding methodological procedures, case studies stood out. Consider that social inequality is one of the main factors that shaped emergency remote learning. Despite all the challenges of the COVID-19 pandemic, several actions and strategies were created to maintain the educational process involving students with ASD, with research playing an important role in this process.

This paper aims to present, in a concise and reflective manner, the experiences, emotions, and learning experiences throughout medical school, from the personal perspective of a student from a public school and a beneficiary of affirmative action policies. The narrative covers the main events that marked the educational trajectory, highlighting the challenges faced, the emotional impacts, and the influences of faculty, colleagues, and institutions on the process of constructing a professional identity. More than proposing solutions, this report seeks to raise relevant questions about medical education, highlighting points of tension and aspects that require further debate and in-depth analysis. The work values subjective experience as a tool for critical analysis and a contribution to improving medical education in Brazil.
