During the settlement house movement in the United States, Hull House (1889–1930) was the setting for experiments that would lay the groundwork for the not yet named Occupational Therapy, which emerged in this context under the influence of various social movements of the Progressive Era, such as feminism and the Arts and Crafts movement. Music was already an established activity at Hull House since 1893. It served as a major cultural center attended by low-income workers and immigrants, coordinated by reformers—mostly women—such as Jane Addams, Ellen Gates Starr, and Eleanor Clarke Slagle. This research is a historical recovery and grouping of archives from this period, highlighting music at Hull House. The methodology used is the interpretive analysis of texts, along with the iconological interpretation of photographic records from the time. In this research, the presence of music at Hull House is revealed in various formats, such as: singing, dancing, musical theater, through instruments and composition, emphasizing the work of musician Eleanor Smith. Music took place in educational settings, such as in classes for children and youth offered by the Hull House Music School, as well as in performances and events for the entire community. This work discusses how these musical activities can be understood as artistic practices that preceded Occupational Therapy, in its sociocultural and therapeutic dimensions, and it aims to contribute to this scarce discussion in the literature.

Introduction: Sedentary behavior (SB) can lead to adverse health outcomes in older adults. During hospitalization, older adults tend to experience an increase in SB, which may remain elevated after discharge. Additionally, hospitalization is considered a stressful event and may contribute to the development or worsening of frailty syndrome. Some studies suggest an association between frailty and SB; however, this relationship is not well understood in the post-hospitalization period. This study aimed to evaluate the relationship between the trajectory of SB and the trajectory of frailty in older adults during the first month after hospital discharge. Methods: This was a longitudinal study in which older adults were assessed at hospital discharge and one month after discharge. SB was measured using the ActivPAL3™ micro accelerometer, and frailty was assessed using the Clinical Frailty Scale (CFS). The association between SB and frailty trajectories was examined using Generalized Estimating Equations (GEE) models. Statistical analyses were conducted using Jamovi software, with statistical significance set at p < 0.05. Results: In the first month after hospital discharge, older adults showed a mean reduction of 57 minutes of SB per day (p = 0.008). Moreover, men spent an average of 122 more minutes per day in SB compared with women (p = 0.002). Each additional year of age was associated with an average increase of 4.88 minutes of SB per day (p = 0.027), and each additional point in the CFS over the 30 days after discharge was associated with an average increase of 37.43 minutes per day of SB (p < 0.001). Conclusion: The findings highlight the importance of considering sedentary behavior as a clinically relevant and potentially modifiable outcome during the hospital-to-home transition period.

Mental health care has historically been marked by segregation, institutionalization and medicalization, often neglecting the individuality and rights of those receiving care. With the advancement of psychiatric reform, there has been a shift toward more humanized approaches, prioritizing treatment in community-based services. In this model, psychiatric beds in general hospitals are designated for acute cases, emphasizing short-term admissions and social reintegration. Within this context, the use of non-pharmacological care strategies becomes crucial, particularly those that foster individuality and autonomy. Among these strategies are expressive workshops, which involve artistic activities and offer spaces for plastic, bodily, musical, and verbal expression. Various authors highlight the importance of art and culture for human development, including psychoanalyst Donald Winnicott, who defines creativity as a means of personal growth and expression. For him, creativity enables individuals to experience and explore the world in unique and meaningful ways, leading to the discovery of the self. Although the literature points to the relevance of expressive workshops in mental health care, there is still a gap in research on their application during inpatient treatment in psychiatric wards within general hospitals. Therefore, this study aimed to investigate the perceptions of both users and health professionals regarding expressive workshops conducted in this setting, analyzing their impact on care processes and psychosocial rehabilitation. A qualitative approach was adopted, using semi-structured interviews with hospitalized users and questionnaires administered to the health team. Data were interpreted through thematic analysis, and the findings were discussed in light of Winnicottian psychoanalysis. Results indicated that the workshops promote emotional expression, social interaction, and the stimulation of autonomy, contributing to more humanized and person-centered care. The conceptual analysis suggested that workshops can serve as a space for care, functioning as a “good-enough” environment that, by fostering transitional space, encourages play, creativity, and subjectivation. These activities may thus support the resumption of emotional development toward independence, aligning with the concept of psychosocial rehabilitation. This study reinforces the importance of recognizing and expanding the use of light care technologies, such as art and culture, as essential tools in psychosocial rehabilitation, ensuring the rights and subjectivity of individuals experiencing psychological distress.

Through a concept that contested the supremacy of neoclassical ideals, emphasizing an aura that was barbaric, irrational, chaotic and mysterious, the Gothic style made its way into the lives of English readers. We can see this in the case of Catherine Morland, a reader of Jane Austen's novel Northanger Abbey (1817). therefore aim to investigate the issue of the rationalization of the Gothic in this novel, based on the discussion proposed by Sandra Guardini Vasconcelos (2002) in her book “Dez lições sobre o romance inglês do século XVIII” – on the emergence of the English novel genre, and also from the method of levels of interpretation in Fredric Jameson's (1992) political reading, contemplating the literary text as a socially symbolic act. I argue that in the novel in hand it would already be possible to observe the idea of the rationalization of the Gothic, not at first reading, since it is directed at a new audience of readers, of the bourgeois order, with this genre appearing at a time of change, just as in the society of the regency period, marked by the transition between aristocracy and bourgeoisie.

This research explores the relationship between poetry and cinema in the work of the poet Marília Garcia. It starts from the premise that the presence of cinema in the author’s poems is intrinsically connected to her theoretical-critical-reflective engagement with the theme of displacement, revealing a critical perspective that acknowledges the centrality of the technical image in the processes of subjectivation and in the perception of time and space, and regards cinema as a privileged medium for thinking about displacement in our time. It is assumed that this art, in Garcia’s poetry, reveals itself in a dual aspect: as a metaphor for the world and as a method of poetic creation. In this sense, the term cinematic consciousness is proposed to designate this relationship with cinema, in which it functions both as a worldview and as a strategy of poetic creation. Accordingly, this poetics is understood to establish, between the poetic image and the cinematic image, a relationship of “otherness” (Paz, 1992), in which cinema figures as the other of poetry—a way of thinking the world and the self. This research thus aims to demonstrate how Garcia mobilizes cinematic ideas and procedures in order to construct her poetics around displacement. For this purpose, Deleuze’s concepts of movement-image and time-image are shown to be essential to understanding why cinema serves as a privileged means for Marília Garcia’s theoretical-critical-reflective approach.

This research aimed to analyze the work carried out by religious therapeutic communities (TCs) located in the municipalities of Araçatuba and Tatuí, in the years 2024 to 2025. We sought to understand the relationship between the activities of these institutions and public policies aimed at treating drug addicts. Specifically, we sought to: a) understand the forms of assistance offered by the State to these institutions, whether through therapeutic protocols, the provision of professionals in the field, or medical supplements; b) sociologically analyze the conceptions of drugs and health imposed by religious therapeutic communities. To conduct this research, we analyzed national protocols on the treatment of drug addicts, as well as internal documents from two selected institutions. The objective of this monograph was to understand the system of isolation and treatment of drug addicts, in addition to investigating how the disciplines and procedures of the internal regimes of these therapeutic communities are applied. The abuse of psychoactive substances can cause serious psychological, family, and social problems. These substances include both illicit drugs—such as cocaine, heroin, and methamphetamine—and legal but equally addictive substances, such as alcohol, tobacco, and prescription medications, such as prescription drugs used to treat anxiety (anxiolytics) and sleep aids (sedatives or sleeping pills), which can cause dependence. These medications include benzodiazepines (such as diazepam and lorazepam), barbiturates, zolpidem, zopiclone, and others. Chemical dependency can affect people of all ages, genders, groups, and social classes, and the signs and symptoms vary depending on the substance and the individual. Religious doctrines offer a moral and ethical framework to help people overcome addiction, while the community can provide emotional and social support. Therapeutic communities are a form of treatment for those struggling with chemical dependency. For this, sociological reflections are of great importance.

Muscle symptoms are common and disabling complaints in Long COVID, however, their pathophysiology remains to be elucidated. Two main hypotheses have been proposed: a local and persistent viral infection or the effects of chronic systemic inflammation. To test these hypotheses, biopsies of the vastus lateralis muscle from individuals with Long COVID and healthy controls were analyzed using Western Blot, immunofluorescence and functional analyses. The results refuted the local infection hypothesis: there was no increase in Spike protein or ACE2 receptor antigens, and the pro-viral protease TMPRSS2 was decreased (p < 0.05). The immune profile was atypical, with a decrease in macrophages (p < 0.05) and no change in T lymphocytes, suggesting immune dysregulation rather than classic cellular inflammation. This dysregulation was associated with tissue remodeling, including selective atrophy of type I and IIA fibers and an unexpected decrease in collagen content (p < 0.05). Functionally, the tissue showed a profound deficit at the cellular level, with a significant reduction in single fiber strength (p < 0.05), a finding not detected in global strength tests. Taken together, these results suggest that muscle pathology in Long COVID is not caused by direct viral damage, but rather by inflammatory and immune dysregulation that leads to atrophy, matrix remodeling and contractile dysfunction at the cellular level.

This dissertation analyzed the digital transformation (DT) process at the Federal University of São Carlos (UFSCar), relating it to the goals and guidelines of Brazil’s Digital Government Strategy (EGD), established by Decree No. 10.332/2020 and Law No. 14.129/2021. The main objective was to investigate how national digital government guidelines have been appropriated and operationalized in the university’s daily management, considering local specificities such as technological infrastructure, human capacities and regional context. For this purpose, the Digital Transformation Plan (PTD), the Information and Communication Technology Master Plan (PDTIC), Management Reports (2018–2024) and minutes of the Digital Governance Committee (CGD) were analyzed. A qualitative approach was adopted, based on documentary analysis and critical interpretation supported by literature on digital government, public administration and digital transformation. The results reveal advances in process digitalization, systems integration and digital services, but also highlight persistent structural challenges such as limited technical staff, budget constraints, fragmented systems and governance gaps. It is concluded that TD at UFSCar is not consolidated solely by virtue of regulations, but requires coordination between technology, financial investment, processes, organizational culture and people management. The study confirms that technology is necessary but not sufficient to generate sustainable public value, and points to ways to strengthen the role of Federal Universities in building an inclusive, secure and transparent digital government.

Environmental, Social, and Governance (ESG) factors, initially applied exclusively within the business context, are beginning to be introduced into the environment of Higher Education Institutions (HEIs). Accordingly, this research aimed to investigate how ESG factors are applied in leading HEIs featured in the QS Sustainability Ranking, through a comparative analysis of institutional reports from both Brazilian and international universities. A qualitative, exploratory, and descriptive research approach was adopted. The research methods included a systematic literature review and documentary analysis of institutional reports and documents found on university websites. One of the main theoretical outcomes of this study is a conceptual framework, developed from the literature review, that compiles dozens of ESG factors applicable to HEIs. Based on the documentary analysis and the proposed framework, ESG factors were investigated in national HEIs (University of São Paulo – USP; University of Campinas – Unicamp; São Paulo State University – Unesp) and international HEIs (University of Toronto; University of California, Berkeley; The University of Manchester). The findings revealed a concentration of ESG initiatives in the environmental dimension, followed by the social dimension, with governance being the least addressed. The comparative analysis showed that the six universities demonstrated a similar performance in terms of the number of ESG factors addressed. However, governance initiatives were found to be more prevalent in foreign universities. It is believed that the results of this study may yield several contributions. The identified ESG factors can support the advancement of sustainability on university campuses, foster stronger relationships between HEIs and the community, and promote teaching and research related to this theme. This study contributes to the ESG and sustainability literature by offering a theoretical framework that can inform university actions, as well as presenting various examples of initiatives already implemented by top-ranked universities in a sustainability index. It is hoped that this work will promote the importance of expanding the application of ESG factors in HEIs, in synergy with businesses, the community, and government, aiming for increasingly widespread implementation of sustainable solutions.

The coronavirus SARS-CoV-2, the infectious agent that causes the disease known as COVID-19, has negatively affected the lives of millions of people since last year. COVID-19 is a multi-organ infection that has significant effects on the musculoskeletal system of infected individuals, causing excessive fatigue, arthralgia, myalgia, muscle damage, and muscle weakness. These symptoms can persist for weeks or even months after the end of the infection, giving rise to what is known as long COVID-19. However, little is known about the effects of SARS-CoV-2 on skeletal muscles, particularly in individuals who did not require ventilatory support and/or hospitalization. Objectives: To assess the impact of the coronavirus SARS-CoV-2 on the human musculoskeletal system, with the aim of contributing to a better understanding of the effects of the infection after its acute phase. Methods: This study included participants divided into a control group and a long-COVID group. They underwent muscle biopsy, blood collection, and isokinetic dynamometer testing for morphological, functional, and biochemical analyses. Results: The long-COVID group showed morphological changes in the vastus lateralis muscle, including decreased capillaries, nitric oxide, and myogenin, accompanied by increased IL-1β, Pax7, and ROS. Functionally, an increase in peak torque was observed during isometric sessions, as well as a reduction in the mean frequency of the electromyographic signal. Conclusion: SARS-CoV-2 infection is associated with muscle changes that can negatively impact the morphology and function of the vastus lateralis muscle in humans, even after the acute period of the disease.

The growing urbanization and accelerated expansion of civil construction has generated a significant increase in construction waste, and even with waste management through the adoption of Transhipment and Sorting Areas (ATTs) and Ecopoints, there are still numerous irregular disposal points in peripheral neighborhoods in several small and medium-sized cities, which generates degradation of the surroundings in critical areas and vulnerable populations with environmental impacts. This study aims to diagnose the management of Construction and Demolition Waste in the municipality of Catanduva/SP, focusing on the Transshipment and Sorting Areas and the Municipal Ecopoint, aiming to identify the factors that lead to clandestine disposal. This is a qualitative and quantitative study, exploratory and descriptive in nature, aimed at analyzing the Construction and Demolition Waste management system in the municipality of Catanduva, São Paulo. The research was conducted with three different samples: four licensed ATTs operated by private companies operating in the municipality, five owners of construction companies working with construction waste C&DW in the municipality, and 109 residents of different neighborhoods, selected by non-probabilistic convenience samples within the municipality. Three different data collection instruments specific to each sample were applied, consisting of a semi-structured questionnaire via Google Forms. Although the municipality adopted measures such as joining the SIGOR (Surveillance System) and creating the Municipal Ecopoint, the discontinuation of two of the four licensed ATTs and the lack of visible public planning for the expansion or replacement of these units compromised the consolidation of a solid and integrated RCC management policy. The lack of updated public data and an environmentally oriented government plan reinforces the need for greater transparency and political commitment to urban sustainability.

This doctoral research investigates the role of writing in the teaching of English to Young Learners (EYL) in the early years of primary school, aiming to contribute to a more meaningful inclusion of this skill in English language classes. Based on a didactic unit designed according to the Communicative Approach (CA) and grounded in the principles of Vygotsky’s Sociocultural Theory (SCT), the study seeks to understand how writing practices in English can be developed with children, reframing writing as a communicative practice from an SCT perspective and drawing on teachers’ perceptions of their own classroom practices. The research was conducted in four public schools in the interior of São Paulo state, with 5th-grade classes. Data were collected through questionnaires, semi-structured interviews with teachers, recorded meetings, and analysis of students’ written productions. Anchored in teachers’ perceptions, the data made it possible to identify how they understand and experience the teaching of writing in the classroom. The study also discusses the concept of the Zone of Proximal Development (ZPD), highlighting the role of mediation and scaffolding in learning to write and in the development of higher psychological functions such as autonomy in textual production. Findings suggest that contextualized writing practices in EYL classes, supported by consistent theoretical foundations, tend to enrich learning and may foster the development of linguistic competencies. Teachers reported indications of greater student engagement, progress across the four skills, and reduced anxiety regarding writing in English. The experience also appears to have encouraged teachers to revisit some of their conceptions, moving toward a more process-oriented and integrated approach guided by mediation and student agency. Finally, the study outlines possible directions for pedagogical practices that may enhance the value of writing in English language teaching for children.

Drug use has been a part of humanity since ancient times, present in different cultures with different motivations. Harmful use can lead to fragility and the rupture of social bonds, isolation, and vulnerability in various aspects of people's lives. In this context, Occupational Therapy works to promote social reintegration and a meaningful daily life. Through activities that are meaningful to the individual, the aim is to rescue abandoned experiences and create possibilities, aiding in their recovery and social reintegration. This doctoral thesis aimed to understand the meaningful activities and daily lives of people suffering from psychological distress due to alcohol and other drug use from their own perspectives. The research, which used a qualitative approach, involved 10 people suffering from psychological distress due to alcohol and other drug use who attended a Psychosocial Care Center for Alcohol and Drugs in a municipality in the Triângulo Mineiro region. The theoretical framework used was the theory of everyday life proposed by Agnes Heller. Data were collected over a five-month period, specifically from February to July 2023, through a sociodemographic questionnaire and an adaptation of the Photovoice method. This consisted of asking participants to take photos of meaningful activities they perform, would like to perform, represent their daily lives, and would like to be part of their daily lives. The data collected through the sociodemographic questionnaire were analyzed descriptively. The data collected through the adapted Photovoice method and the interview guide were analyzed using thematic content analysis, from which three categories of analysis emerged: What is meaningful to do: human activities; A daily life of meaningful activities; Using drugs is a meaningful activity (yes)! The results showed that participants attributed different meanings to meaningful activities and daily life, including the use of psychoactive substances itself. Daily life was understood as a daily routine composed of various activities, in addition to care/assistance activities, interpersonal relationships, and work activities. The data revealed that drug use influences the performance of meaningful activities and the daily lives of participants, but that it can also be considered a meaningful activity in people's lives. The research findings demonstrated the relevance of the Alcohol and Drug Psychosocial Care Center and the development of feelings of belonging in the contexts in which people with psychological distress due to alcohol and other drug use live for the performance of meaningful activities and the redefinition of their daily lives. Based on the theoretical framework adopted, it was possible to analyze the influence of psychological distress and drug use on the daily lives of participants. The study demonstrates the importance of considering the perspectives of people with psychological distress due to alcohol and other drug use in valuing their meaningful activities and redefining their daily lives, enabling qualification for this area of Occupational Therapy.

This study aims to develop and evaluate Automatic Speech Recognition (ASR) systems tailored to the needs of individuals with dysarthric speech — a condition that compromises communication clarity and limits the use of voice-based assistive technologies. One of the main challenges in dysarthric speech recognition lies in the scarcity of labeled data, and to address this issue, two complementary and interdependent approaches were examined. The first investigated pathology-oriented data augmentation techniques applied to two Transformer-based processing pipelines: FW1 and FW2. Signal perturbation methods — additive noise, time-stretching, and the proposed Spectral Oclution (SO) — were applied individually and in combination to recordings from the UA-Speech corpus. Exploratory analysis of Word Recognition Accuracy (WRA), Word Error Rate (WER), and Character Error Rate (CER) curves showed that combining noise and time-stretching consistently reduced errors in speakers with moderate intelligibility; SO provided additional gains in specific cases; and the union of all three perturbations benefited severe cases, although it could degrade nearly typical voices due to spectral overheating. The second approach, built upon the findings of the first, employed supervised pre-training on typical speech from the LJSpeech corpus. These baseline models were then subjected to a self-supervised contrastive cycle on the typical partition of UA-Speech, where the same transformations from Phase 1 (noise, time-stretching, and SO) were reused to generate positive pairs for contrastive training. Thus, augmentation strategies were not only validated in isolation but also served as the foundation for the contrastive stage. We evaluated two methods: Simple Framework for Contrastive Learning of Visual Representations (SimCLR) and Swapping Assignments between Views (SwAV). The refined weights were then transferred for fine-tuning on dysarthric datasets. Compared to the baseline trained solely on LJSpeech, both contrastive methods enhanced performance: SimCLR showed higher sensitivity to severe speakers, while SwAV maintained stable performance across all intelligibility levels, further reducing CER and WER and increasing WRA. In some severe cases, WER was reduced by more than 20 percentage points. In summary, the integration of targeted data augmentation and contrastive pre-training resulted in ASR models more robust to the articulatory variability of dysarthria, supporting the inclusion of dysarthric speakers in voice-based communication systems.

This research aims to describe and analyze hesitation in interactions carried out through customer service chats that use Artificial Intelligence (AI) systems, based on the Interactive Textual Perspective (Jubran, 2006). The investigation focuses on identifying and describing the linguistic markers of hesitation in interactions mediated by three types of interlocutors: human agents, users, and a chatbot, as well as verifying how these markers manifest and impact the perception of fluency, comprehension, and humanization in dialogue. The study is grounded in the understanding of AI as a technical field that also seeks to develop agents capable of simulating human behavior (Russell; Norvig, 2016; Nilsson, 1998), with particular focus on automated conversational systems (Jurafsky; Martin, 2023), such as chatbots, which constitute hybrid environments between orality and writing. In this context, hesitation is defined as an interactive-discursive phenomenon with a textual function, capable of signaling doubt, organizing discourse, and seeking cooperation, as discussed by Marcuschi (1999), Marcuschi (2000). The analyzed data are drawn from a corpus of real customer service interactions conducted by a nationally recognized company that authorized the use of the data. The methodology involves the qualitative and quantitative categorization of hesitation markers according to linguistic criteria, including frequency of hesitations, type of hesitation, communicative context, impact on interactions, user response, human vs. AI comparison, conversation length, pragmatics of hesitation, cognitive aspect of hesitation, and interactional aspect of hesitation. The analysis shows that hesitation, when more frequent among human interlocutors—mainly in functional words and hesitation markers—is associated with interactions that generate effects of empathy and cooperation from users. In contrast, the absence or superficial simulation of this phenomenon in AI turns compromises the continuity and naturalness of the interaction. By situating hesitation as an important element in the construction and fluency of conversations mediated by humans and robots, this research explores and connects the subject to the field of technology and may contribute to studies on the humanization of AI in automated customer service, reinforcing the importance of integrating linguistic, pragmatic, and technological aspects in the design of conversational systems that are more sensitive to natural language.

When we reflect on authorship, we can shed light on a multitude of perspectives and ideas that draw us to both literary studies and discourse studies, making this concept, in its own way, the result of discussions and practices that constantly call the author into question. In this context, Dominique Maingueneau, in Literary Discourse (2006), posits that the author is composed of three instances that function intertwined and simultaneously—namely, the person, the writer, and the inscriber—thus giving shape to the authorial work. However, in Ten Concepts in Discourse Analysis (2010), by proposing the notion of the author’s image, Maingueneau challenges his own formulation of authorship by arguing that the work with the text and the construction of a work are not the exclusive domain of the author, but also of managers, commentators, and interveners who, together, shape the image one has of the author, as well as help mold that image into positive or negative values. From this perspective, we seek to understand the functioning and management of the authorship of Carolina Maria de Jesus and Conceição Evaristo, examining two lines of analysis, respectively, each with a different starting point, that is, with distinct materials and excerpts. To this end, within the framework of discursive studies, we draw on the concept of the author’s image (Maingueneau, 2006, 2010) to examine the functioning of authorship and the management of Carolina and Conceição’s authorial image, constructing two analytical trajectories based on Maingueneau’s (2007) notion of the “trajectory” as a non-topical unit. Following the analyses, it was possible to observe that the functioning of authorship and the construction and management of an author’s image occur, on the one hand, through the materials and excerpts analyzed by the researcher and, on the other, simultaneously through the authorial work itself as well as through the managers, commentators, and interveners of the work — while the authorship and construction of Carolina Maria de Jesus’s authorial image are currently managed by posthumous interveners, Conceição Evaristo exercises her own active management because she is alive, yet her authorial image is still valued by interveners and commentators, demonstrating that authorship, far from being the exclusive domain of the author, is markedly dynamic and determined by various factors.

Several clinical situations require surgeries that reduce the volume of the orbital cavity, making it necessary to replace this volume to preserve the patient's aesthetics. There is still no consensus on the ideal material for this. A promising alternative is the Biosilicate implant, already clinically tested. However, its fabrication by melt-solidification limits the creation of complex shapes. In this context, the digital light process (DLP) emerges as a ceramic additive manufacturing technique that offers high surface quality and dimensional accuracy. Therefore, the objective of this study was to manufacture, in a novel way, intraorbital implants based on Biosilicate using the DLP technique. Biosilicate was successfully obtained and characterized using differential scanning calorimetry (DSC) and X-ray fluorescence (XRF) analysis. The effects of milling with and without solvent were demonstrated through dilatometric analyses. Sintering can be performed at 950°C without significant foaming, preserving the integrity of the printed structure. With the Biosilicate in hand, the suspension was prepared for DLP printing, aiming for high solids concentration and good stability. Rheological studies with different solids (30, 40, and 50% vol) and dispersant (0.1–5% vol) contents indicated that the formulation with 40% solids and 5% dispersant, although presenting a viscosity slightly above the ideal value, was considered suitable and chosen for printing the intraorbital implants. The implants were successfully printed, resulting in defect-free, gyroid-like parts after the thermal debinding and sintering processes. In vitro bioactivity tests in simulated body fluid (SBF) showed the formation of hydroxycarbonate apatite (HCA) after only 6 hours of immersion.

This study focuses on public use (PU) and ecotourism in the Capão Bonito Forest (FLONA), with a particular emphasis on planning ecotourism itineraries for the Visitation, Interpretation, and Environmental Education Program in the Conservation Unit (UC). The UC is located in the state of São Paulo (SP) and covers the municipalities of Buri and Capão Bonito. Located in an area of high ecological and sociocultural importance, the study aimed to evaluate potential itineraries and attractions that could contribute to the UC's visitation program. The study sought to diversify ecotourism practices by considering different visitor profiles and demands. Ten itineraries were evaluated based on the attributes and indicators of the List of Visitation Opportunities in Conservation Units (ROVUC) and were classified according to the experience classes suggested by the ROVUC. In conclusion, FLONA has high ecotourism potential, offering diverse experiences aligned with the management zones. A Public Use Plan should be developed to regulate public visitation and integrate conservation, education, and local development.
