This work aimed to investigate the physical health of Brazilian Sign Language (Libras)/Portuguese Language Translators and Interpreters (TILS) who work in schools. It was intended to problematize the working conditions and possible health problems that may be presented by these professionals as a result of their working conditions. This is a qualitative and exploratory research, in which online questionnaires were applied to TILS professionals in the State of São Paulo, who worked in Elementary School or had worked in the last two years. Ten professionals participated in the study. The questionnaire had objective and essay questions that dealt with the physical health and working conditions of professionals. Data analysis was carried out according to the laws that guides the work of TILS and of studies that deal with the physical health of Brazilian Sign Language (Libras)/Portuguese Language Translators and Interpreters (TILS) who work in the school environment. The results indicate different factors that can lead TILS to develop diseases such as repetitive strain injury work- related muculoskeletal disorders (WRMD) due to repetitive movements.

In the current Brazilian scenario, one of the facets of violence that most kills individuals is violence motivated by homophobia. One of the forms of homophobia that has the potential to be traumatic for the victims, and which lacks in-depth studies - especially in the areas of qualitative research and psychoanalysis - is that which comes from the family environment, called intrafamilial homophobia. The present study sought to investigate how intrafamilial homophobia can cause long-term traumatic effects on subjectivity, through the qualitative research approach "Method of Narrative Interviews of Free Association", and based on Sándor Ferenczi's theory of trauma. For this, four homosexual men were interviewed, of which two suffered explicit intrafamilial homophobia and two implicit intrafamilial homophobia.

The present work aims to collaborate with the management of urban green spaces through the technologies of geographic information systems. These spaces impact the life of the population through the provision of ecosystem services, cultural and environmental quality regulation. Based on the mapping of areas available on the SIGAVERDE platform (https://sigaverde.web.app/map), the objective was to validate its operation by monitoring maintenance/cutting/pruning process and verifying the indexes corresponding to vegetation growth. The observation of the vegetation growth rate of Bahiagrass species is intended to facilitate the management of the maintenance/cleaning of a previously delimited area or lot, predicting the growth time, and indicating when the grass is tall, as well as allow the user to register on the platform when maintenance is carried out, thus optimizing the planning processes for better management. The model simulates growth by measuring some environmental stresses, such as water availability and radiation. Seeking to evaluate the model, we used vegetation indices (NDVI and EVI2) obtained from the PlanetScope satellite to estimate the leaf area index (LAIP) and compare this with the model outputs, which return LAI and biomass values. The results show that the model fits relatively well to the real scenario, although there were setbacks in the platform update. With some adaptations for operational conditions, it is believed that it has a lot to contribute to the municipal administration, adding management efficiency, collective participation of citizens and conservation of the environment.

En este trabajo de conclusión de curso, presento una propuesta de producción audiovisual bilingüe, en la que se destaca Libras para la presentación y discusión del tema que trata sobre la reflexión del cuerpo del traductor/intérprete de Lengua Portuguesa/Libras (TILSP), específicamente el cuerpo Trans (poco visto en este campo profesional), sus cruces, desafíos y potencia en el contexto de la traducción e interpretación de Libras y en el campo de la sordera. En este sentido, mi objetivo fue desarrollar/crear/producir material audiovisual, de carácter autobiográfico, accesible a personas sordas y oyentes, quienes puedan beneficiarse de la producción para la reflexión y discusión sobre la idea canónica del cuerpo del profesional. Libras traductor e intérprete, así como la inclusión y las diferencias y sus diversas posibilidades de intersección dentro de este campo de actividad, en este caso un cuerpo travesti asumiendo la posición de intérprete. El material editado y finalizado estará disponible de forma gratuita en el canal de YouTube del curso TILSP, así como el guión en portugués y la sistematización y fundamentación teórica remitidos posteriormente en la plataforma de la biblioteca pública de la Universidad. Como resultado, espero contribuir a incitar a la reflexión crítica sobre la diversidad de los cuerpos, para proponer un replanteamiento de las representaciones de TILS y, a su vez, en la imaginación del sentido común, hacia el escenario de los Traductores e Intérpretes de Libras.

In this work, we propose one of the many possible ways in which the scientific method can be introduced in different schools, utilizing simple materials such as a ruler, paper, a twelve-sided die, and creativity. The objective is to promote the development of scientific thinking in high school students through pedagogical interventions, involving activities related to both science and pseudoscience in the classroom. Pseudoscience is represented by Astrology, and the activity is divided into two parts: in the first phase, each student must choose one of the twelve presented characteristics that they identify with the most, and then roll a twelve-sided die, noting the upper face that appears. The idea is to demonstrate that both events are random. On the other hand, science is represented by the scientific method, and the activity involves calculating the area of three different rectangles, so that in the end, students realize that the precision of calculations results from errors and refinements throughout the process. The results obtained show that the majority of personality descriptions chosen by each student do not coincide with their birth sign and follow a random distribution, much like the numbers obtained from the die. They also demonstrate that the values of the area for the rectangle with a more defined border deviate much less compared to the one with a thicker border. This is because achieving a value closer to reality requires adjusting materials, methods, and discussing conclusions with others. This approach allows students to discover connections between different topics, such as the concept of measurement involved in calculating the areas of a simple geometric figure, in this case, the rectangle, and the randomness associated with Western Astrology sun signs.

Biosurfactants are multifunctional compounds of microbial origin of industrial and environmental interest due to their surfactant and emulsifying properties of biodegradable nature and low toxicity. Several culture media and carbon sources are used in the production of these compounds, as well as a wide variety of microorganisms, isolated from multiple environments. The present work aims to promote a bioprospection in the microbiota associated with fruit residues (orange, mango and fruit mix) in order to identify the genetic composition of this microbiota related to the biosynthesis of biosurfactants. For this, the residues were evaluated through a metagenomic approach, where the genetic potential of their associated microbiota for biosurfactant biosynthesis was determined. The residues presented a common core that includes the genera Klebsiella, Enterobacter, Stenotrophomonas, Acinetobacter and Escherichia and similar functional profiles related to biosurfactant biosynthesis, presenting a genetic potential mainly for lipopeptide biosynthesis, with emphasis on genes related to the biosynthesis of putisolvins, mycosubitilin and iturin A. The taxonomic assignments to the genes present in higher abundance in the samples were related to the common core found. From the metagenome, 34 genomes (MAGs) were retrieved, 10 of which were of high quality, which were evaluated for genes related to the production of biosurfactants. MAGs showed genetic potential for the biosynthesis of biosurfactants, especially lipopeptides, corroborating the metagenomic analysis. The MAG OB01 taxonomically identified as Brevibacillus laterosporus stood out for the number of assigned genes. Subsequently, the microorganism isolated from mango residue, identified as Brevibacillus borstelensis ISM04, was used in the fermentation process for the production of biosurfactant using glycerol as a carbon source. The produced biosurfactant showed an emulsifying activity of 67 % in kerosene and showed thermal stability up to 80 °C and at pH range between 6 and 10, in addition, it did not show toxicity in tomato and lettuce seeds. The compound produced was partially characterized and the analyzes suggest that it is a lipopeptide biosurfactant.

The aim of this paper is to critically analyze the environmental education activities carried out by the Australis Institute in Imbituba/SC during "Whale Month", which celebrates the month with the highest number of right whales (Eubalaena australis) on the southern coast of Santa Catarina. This analysis sought to identify the limits and potential of the educational practices carried out by the Australis Institute team during this month, in 2021, adopting the concepts of dialogue, problematization, contextualization and interdisciplinarity conceived within the framework of the foundations of Critical-Transformative Environmental Education via generating themes as an analytical framework. The results of the analysis reinforce the importance of carrying out activities that address environmental problems, aim to increase visitors' criticality and lead them to critically reflect on the issues addressed, so that they become more aware and can once again feel part of nature, and the analysis also points to new forms of educational approach during the application of the activities developed, using interdisciplinarity as a key point.

En este trabajo de conclusión de curso, presento una propuesta de producción audiovisual bilingüe, en la que Libras se destaca por la presentación y discusión del tema que trata sobre la educación de las personas sordas y los desafíos que enfrentan los estudiantes sordos en una de las escuelas de la Red. Municipio municipal de São Paulo de Olivença, en el interior de Amazonas. En este sentido, desarrollé material audiovisual accesible a personas sordas y oyentes, quienes pueden beneficiarse de la producción. El trabajo muestra la realidad de la educación de los sordos y los desafíos que enfrentan al adquirir educación sin la presencia de un intérprete Libras profesional, discutiendo más específicamente las dificultades que enfrentan estos estudiantes ante la falta de un intérprete Libras profesional para trabajar en la educación. A partir de una encuesta realizada en una de las escuelas municipales que atienden a estos niños y adolescentes sordos, y en entrevistas realizadas al director de la escuela, se buscó identificar qué prácticas utilizan los docentes de la escuela en el proceso de enseñanza a los estudiantes, presentando y discutir las estrategias de enseñanza presentadas, problematizando la ausencia de intérpretes profesionales que los asistan, a pesar de que existe una legislación nacional que garantiza el acceso de las personas sordas a la educación.

The presence of the Deaf Instructor in school contexts is a recent development when compared to the entire history of deaf education in Brazil. This professional, who is part of the proposal for bilingual education, has as his main function to provide the reaffirmation of the identity of deaf students, their specificities, and the valorization of their language and culture. This motivated the research regarding the performance of this professional, since the work of the Deaf Instructor is still little explored in the field of education. The aim of this research was to investigate how the Deaf Instructor's work is carried out, seeking to understand how this work is done and what strategies are used in their workshop to promote the learning of deaf children, considering in this learning the construction of the deaf child's identity and also the valorization of their language and culture. Data collection was carried out through observation of their work in the classroom with deaf children in early childhood education, with records in a field diary, in order to report the practices developed by this professional. It was possible to identify the importance of play in the relationship between the Instructor and the student, based on Vygotsky's studies on language development, mediated by a more experienced adult and the role of play in this acquisition process. The data presented are excerpts from these reports, analyzed in light of studies on language development and deaf identity. The results indicate that the work of the Deaf Instructor is fundamental in the development of the child, focusing not only on teaching (Brazilian Sign Language) Libras, but also on play, relationships, and giving meaning to the elements present in communication, enabling them to acquire knowledge of the world.

Youth and Adult Education (EJA), a basic education modality, has historically faced invisibility in official education documents in Brazil. The objective of this paper is to analyze how this modality is addressed in recent official education documents: the National Common Curricular Base (BNCC) and the São Paulo Curriculum (CP). In addition, it aims to delve deeper into the discussion of the political context surrounding this modality from the 20th century to the present day. To this end, qualitative and documentary research was applied through the exploration of the aforementioned documents. Regarding the perspectives obtained in the National Common Curriculum Base, Youth and Adult Education is little explored in the introduction and does not have any further visibility throughout the document. Regarding the perspectives obtained in the São Paulo Curriculum (CP), Youth and Adult Education has a space in the document with visibility to show that it is a basic education modality and to explore its specificity. The document takes the opportunity to develop the following fact: the methodologies applied in regular education are not applicable to EJA due to the diversity of the subjects and their experiences. The results corroborate the invisibility of Youth and Adult Education (EJA) in the documents, leading to the understanding that this modality has suffered and still suffers from disrespect from government agencies. The investigation helps to reinforce that the documents analyzed serve thousands of people and that this could be an opportunity to, even if minimally, guide curricular paths for this audience.

The puerperal pregnancy cycle marks a period of intense changes in the woman's psyche and body, filled with particular emotional demands. Childbirth is an emotionally relevant event, which, depending on its consequences, can significantly impact maternal mental health. The aim of the study is to understand, from the maternal perspective, how the experience of childbirth took place and the thoughts, feelings and emotions involved in this process. To this end, 6 women, recruited in the third trimester of pregnancy, took role in the study. Participants answered a characterization questionnaire, two semi-structured interviews (prenatal and postnatal), the Childbirth Violence Assessment Questionnaire and the Edinburgh Postpartum Depression Scale (EPDS). Quantitative data were analyzed using descriptive statistics, while qualitative data were analyzed using Interpretive Phenomenological Analysis (IPA). Four of the six interviewees experienced some type of violence during childbirth and two had scores that suggest more intense distress symptoms. The analysis of childbirth reports highlights the diversity of perceptions and emotions in relation to pregnancy and childbirth. The study also emphasized the importance of expectations and the perception of control for the women involved, and the importance of a positive relationship between mothers and health professionals in shaping a positive childbirth experience.

This study addresses the importance of accessibility in health campaigns aimed at the deaf community, highlighting the need to overcome challenges to ensure full social inclusion. Although legislation has advanced, there are still obstacles to ensuring the inclusion of Brazilian Sign Language (Libras) in these contexts. The main objective of the research was to evaluate the accessibility of health campaign videos on the official YouTube channel of the Government of the State of São Paulo, between February 2022 and February 2023. During the analysis, 21 videos related to the theme "health" were found during this period. The evaluation took into account the presence of a Libras interpreter or Libras window, the provision of subtitles, and the use of images and visual resources. The results showed that, in some cases, resources were adopted to make the content accessible, such as interpreters, Libras windows, plain language, and complementary images. The analyses indicate that the inclusion of interpreters or Libras windows, combined with the use of visual resources and more accessible language, is essential to ensure the effective inclusion of the deaf community. Despite the progress, it is still necessary to pressure the government to improve accessibility in health campaigns, ensuring equal access to information and health care for all.

Bertholletia excelsa, also known as the Brazil nut tree, stands out as a dominant and safeguarded species within the ecosystem, serving a pivotal function in the cycling of nutrients and the delivery of essential ecosystem services in the Amazon rainforest. This study aimed to model the suitable habitat distribution of this species, by comparing different ensemble models constructed using various spatial filtering resolutions. Additionally, we aimed to include an evaluation of the influence of human activities in promoting or dispersing B. excelsa seeds and/or stands. The results highlight the impact of model selection on the present and future projections, with a significant difference between the projections for the 2050s. We emphasise the importance of considering multiple models for different climatic conditions to better assess the uncertainty of future projections when making climate change policies. The best model (AUC = 0.94) was achieved with geographic plus environmental filtering and a resolution of 2.5 arcminutes. The model predicted a contraction of the suitable habitat area for Brazil nut trees in the present and an even more severe scenario in the future, with precipitation seasonality being the most impactful variable in the species distribution. Future studies should also examine the expected impacts of climate change on the seed production of Brazil nut trees, including indirect effects such as changes in pest and disease incidence.

Devices known as prostheses and orthotics are commonly used to aid mobility and improve the quality of life of people with disabilities, supplying and meeting biomechanical needs for the absence of limbs or treatment and functionality of the musculoskeletal system. However, in Brazil there are not many properly documented projects on how to perform the necessary tests and performance validations of these same devices for the necessary reliability for development. Thus, the objective of this work is to design a virtual transtibial prosthesis, detailing the processes and validating the performance by CAD/CAE based on international parameterizations in accordance with the current standards on the subject. Initially, a modeling of all the necessary components was made in CAD. Subsequently, a simulation of the complete structure and parameters for declared configurations was carried out, which resulted in a proposal for a prototype with proof test validations of the static type with loading conditions for patients of up to 100 kg. Acceptable values of forces, deformations and safety coefficients were obtained for the structure, validating the process and applied methodology.

The present work aims to analyze how high school textbooks, approved in the National Textbook and Learning Material Program (PNLD) 2021, approach Genetics content and all its complexity. The teaching of Genetics, as well as that of Biology in general, to be effective and meaningful, must be based on the assumptions of STS education (Science, Technology, and Society) and the progressive education of Paulo Freire, to form critical citizens and aware of their realities, capable of transforming them. Genetics is a complex area in continuous development, difficult to understand and with many challenges in its teaching, the main one being the prioritization of the textbook as a teaching tool, wich has the potential for the formation of critical citizens, if aligned with critical and emancipatory perspectives of education. Therefore, sought to analyze how this area is being approached in eight textbooks distributed to the public school system by the PNLD, using qualitative research and document analysis methodologies, based on the aspects: I) approach to genetics and relation with other areas of Biology and Natural Sciences; II) Approach of the history of science; III) Language complexity and explanation of concepts, IV) Approaching content to students' lives and V) Approach of New Biology and Genetic Counseling. From these aspects, it was possible to observe that there is a concern to make textbooks less content-oriented and more connected with the development of student's critical thinking, making teaching go against STS education and emancipatory education, despite still needing constant attention and updating.

Children and adults learn new information in different ways: through direct experience and the testimony of people around them. It is therefore necessary for children to select who, among these people, is trustworthy. Recent research has revealed that children use not only epistemic criteria (e.g., who seems to have the most knowledge about a subject) but also non-epistemic cues to accept informants or information. For example, when two possible informants prove to be equally competent, young children show a preference for an informant who looks more like them (e.g., of the same gender or a native speaker of their language, as opposed to someone who speaks with an accent). When there is evidence of the same reliability history from two possible informants, will children choose the one with a similar accent to their own or the one with the same gender? To answer this question, 73 children aged between 4 and 5 years (Mage = 4 years and 6 months; SDage = 6 months) participated and were administered a selective trust task. Initially, during a familiarization phase, children were shown an animated video in which the characters narrated early parts of the story "The Three Little Pigs", which enabled them to identify the presence of an accent and the gender difference between two informants. During the test phase, the two informants provided conflicting information about the location of a lost object and the child had to choose the testimony of one of them. Participants were randomly assigned to three conditions. For each condition, there were male and female participants. In Condition 1, the two characters were a man and a woman, both with foreign accents. In Condition 2, the informants were a man with a foreign accent and a woman who is a native Portuguese speaker. Condition 3 featured a man who is a native Portuguese speaker and a woman with a foreign accent. No age effect was found in the choice of informants. Data analysis showed that children preferred informants with the same gender as their own (in detriment to those of a different gender) in all conditions. In C1 and C3, significant differences between boys and girls were found with regard to both the preference and the endorsement measures. However, in C2, a significant gender effect was only found for the preference measure. Together, these results are consistent with previous studies suggesting that informants’gender may be more important than accent in their selective trust judgments. Despite the fact that many studies on the topic have been conducted, more research investigating the relationship between different characteristics of the informants is needed.

The development of technologies to combat microplastics in the marine environment contributes to achieving the goals of the Ocean Decade in the 2030 Agenda. In this context, this research explores the degradation efficiency of microplastics (5 mm) of the polypropylene (PP) type by halophiles induced from the soil simulating marine conditions (salinity 3.5%) as an optimized alternative for depollution, evaluating microbial degradation through the evolution of CO2, given that soil microorganisms have nutritional plasticity and can seek alternative sources of food and when capable of survive environments with high salinity are classified as halophilic microorganisms, this class being more likely to degrade polymers. The use of PP as a material to be degraded is due to the fact that it is one of the most produced non-biodegradable plastic materials worldwide and its presence in the oceans is also the largest. Therefore, the four bacteria were selected from soil collected on the premises of UFSCar-CCA (Araras) and induced into the simulated marine environment. These bacteria were part of the respirometric biodegradation tests, lasting 56 days, in which weekly titrations were carried out to measure CO2 production, this being the main method chosen to evaluate the biodegradation of PP. The material was subjected to two treatments: one with exposure to UV (PPt UV) and the other without treatment (PPi). Subsequent tests verified the interaction and transformations in the polymer, such as (i) colorimetry, (ii) Fourier transform infrared spectroscopy (FTIR), (iii) scanning electron microscopy (SEM), (iv) the percentage of mass loss, (v) substrate consumption tests in solid media to evaluate the presence of microorganisms embedded in the PP after biodegradation, and (vi) ecotoxicity tests with Lactuca sativa. The results of biodegradation through the production of CO2 indicated activity for all four isolates, identified as AS1, AS3, AS4 and AS5, with the AS1 and AS4 strains being the most effective in degrading PP. The data regarding the biodegradation of PP by the AS1 lineage, when it consumes PPt (UV) and PPi, obtains a higher production of CO2, with a difference of 28.3% and 20%, respectively, more compared to the control group in that the AS1 lineage is found consuming only the culture medium and when comparing the PPt (UV) and PPi data associated with the AS4 lineage it is possible to observe an increase of 17% more when the PP undergoes UV treatment. Another interesting fact is the toxicity present in the substrate resulting from the biodegradation of PP on all strains, proving that the degradation pathways of this polymer must be explored in order to develop better studies. Therefore, from this experiment, the evaluation of the biodegradation of PP by soil microorganisms induced in the marine environment, brought significant biodegradation results, mainly from the AS1 and AS4 lineages, obtaining an even greater oxidative degradation when the PP is treated with UV, reveal are microorganisms with great biotechnological potential for PP degradation in marine waters. This research also contributes to more in-depth discussions about the adaptation mechanisms of microorganisms and their multiple functionalities, in addition to proposing studies on the toxicity of biodegradation byproducts with other test organisms.

The Botucatu Formation is globally renowned for its ichnofossils. Originally part of a massive paleodesert from the early Cretaceous Period, the Formation consists of aeolian sandstones, with one of its main outcrop areas located in the municipality of São Carlos. Here, we aimed to conduct a survey and analysis of the ichnofossil diversity found in the public roads of the municipality, with the intention of documenting and preserving the fossil heritage present within them. Using the Street View tool on the Google Maps platform, a survey of locations featuring Botucatu Sandstone slabs was conducted. Subsequently, the obtained addresses were physically visited to assess the condition of the slabs and the presence or absence of fossil records. These sites were photographed to create a database. In total, a sum of 1285 locations containing Botucatu Sandstone slabs, some of which presented fossil traces were identified, ranging from invertebrates to mammals, theropod and ornithopod dinosaurs. There is a significant diversity within these groups, with 487 addresses displaying traces of invertebrates, 28 of mammals, and 21 of dinosaurs. Additionally, a loss of this collection was observed at a rate of 1% per month. Preserving this "open-air collection" is therefore of great scientific and national interest, with the present study potentially serving as a basis for drafting new laws for its preservation or as supplementary material for future studies on the fossil heritage of São Carlos.
