El estudio tuvo como objetivo identificar los niveles de desarrollo del pensamiento geométrico en los estudiantes involucrados en la resolución de preguntas en la primera fase de OBMEP, nivel 3, basado en la producción de prototipos visuales. La contribución teórica de la investigación fue la teoría de Van Hiele y la Ingeniería Didáctica, la opción de metodología de investigación. Los sujetos que participaron en la investigación fueron 22 estudiantes del tercer año de secundaria en una escuela pública en Taquaritinga do Norte - PE, miembros del programa OBMEP en la escuela. Para cumplir con el propósito de la investigación, se llevaron a cabo tres reuniones con los estudiantes, cuya producción de información presentada para el análisis resultó de fotografías, registros escritos y diálogos entre maestros y estudiantes. En la primera reunión, las actividades de los estudiantes se llevaron a cabo con lápiz y papel. En la segunda reunión, la pizarra digital y el software GeoGebra se utilizaron como dispositivos digitales para el desarrollo de un prototipo visual, es decir, la construcción de una figura geométrica basada en el enunciado de una pregunta. Finalmente, en la tercera reunión, solo GeoGebra se utilizó para reproducir figuras geométricas de las declaraciones de cinco preguntas objetivas, en forma de prototipos visuales para ayudar a resolver estos problemas. Como resultado de la investigación, GeoGebra contribuyó a la transición del primer al tercer nivel de pensamiento geométrico, además de presentarse como un recurso con el potencial para resolver preguntas objetivas de la primera fase de OBMEP, cuyas declaraciones integran figuras geométricas.

Multi-label classification a machine learning task whose objective is to generate models capable of learning relationships between descriptive characteristics of objects and the sets of classes to which such objects belong. In certain applications, it is important for the models to be interpretable so that their users can trust it or so that its predictions can be explained. In this research, we investigated the generation of multi-label classification models based on consistent sets of rules. We proposed an evolutionary algorithm and two auxiliary algorithms that guide the rule generation process, ensuring that the rules created were consistent with each other. A set of rules is consistent if whenever multiple rules covers an object, such rules predict the same set of classes. The proposed evolutionary algorithm utilized multi-objective optimization techniques to generate collections of classification models that offer different compromises between interpretability and predictive power. Experiments were conducted with the proposed algorithms and with algorithms from the literature and, based on statistical analysis, we concluded that the generated models were, in terms of interpretability, superior to those generated by literature's algorithms and, in terms of predictive power, they were comparable to most.

This qualitative and exploratory study aims to analyze the perspectives of a group of foreign language learners about what they claim to have learned from the English language, mostly through music and without the mediation of a teacher. In addition, we seek to find out how these students explain the English language learning, seeking to recognize the interfaces between their statements and their strategies for learning the target language. To this end, we rely on studies on the approach and / or culture of learning languages conducted by Almeida Filho (2010, 2014 and 2015) and which address precepts or practices underlying the act of learning a Foreign Language. We focus, through the studies of Ferraço de Paula (2008), on the spontaneous competence of learning languages whose approach is determined by the traditions of learning and reflected in the practices and habits of studying. We were also interested in investigating how factors such as learning strategies, Oxford (2003), used by the research participants reflect their culture of learning languages. Other fundamentals and concepts, likewise, served as supporting pillars for the development of this study, such as motivation in the context of foreign language learning, Gardner (2005, 2010, 2012) and Deci and Ryan (1975, 2000). Studies by other researchers also contributed to the composition of the theoretical framework. To the data production, this research included a semi-structured questionnaire and an interview script that guided us in conducting this study. Through data analysis, the following results can be obtained: language spontaneous competence is evident in the procedures demonstrated by the participants. The recognition of the culture of learning languages and the learning strategies adopted by these learners influenced by their peculiar styles of learning and by an intrinsic orientation allowed us to glimpse their attitudes, beliefs and motivations in conducting their autonomous learning.

The city of Cumari is located in the southeast of Goiás state and is predominantly covered by the Brazilian Savanna (Cerrado). This biome is considered a biodiversity hotspot and for this reason this area has priority for conservation actions. The Cerrado Mammals Conservation Program (Programa de Conservação Mamíferos do Cerrado - PCMC) promotes some of these actions through its diverse research with carnivores of the region (especially canids). However, the PCMC team recognize the need to improve environmental education actions for conservation with the local community. To fill this gap, the present research sought to understand how the application of diagnostics and participatory methodologies can assist in the planning and execution of actions that comprise a process of community engagement in socio-environmental issues and scientific research. This process was based in critical environmental education (EE) and participatory methodologies like Intervention Research, Action-Research, Social Learning and Citizen Science. The first stage thorough a meticulous collaborative diagnosis of the community using questionnaires and group interviews (focal group) to establish and characterize the main research participant-public (teenagers - high school students) and what actions would be taken. Following the diagnosis conclusion, the second stage was initiated, which consisted of educational interventions with the participant-public, such as EE actions, research activities and diffusion actions. Throughout this process some challenges have arisen, however the community actively collaborated in all actions, as well as became familiar and in close contact with conservation and science research conducted in the region. In addition, the community interest in participate and contribute to local socio-environmental issues was observed.

Introduction: The evaluation of the pelvic floor musculature (MAP) is important because through this it is possible to verify possible dysfunctions of the floor musculature pelvic floor (DMAP) that can have repercussions in urinary and fecal incontinence, prolapse of pelvic organs and sexual dysfunction Therefore, one of the methods of evaluating the MAP's function is through bidigital palpation using the PERFECT scheme. Objective: To evaluate the inter and intra-examiner reproducibility of the PERFECT scheme for evaluation of the pelvic floor musculature by means of bidigital vaginal palpation. Materials and methods: This is a test-retest reproducibility study. Were 41 women were evaluated, with a mean age of 23.7 years old (with standard deviation 3.9). A researcher carried out the participants' anamnesis and randomization of the order of the examiners who underwent bidigital vaginal palpation and graduation of the MAP function through the PERFECT scheme (P = ”power”, voluntary contraction maximum (CVM); E = "endurance", maximum sustained contraction (CSM); R = ”repetition”, repetitions of CSM contractions; F = ”fast”, repetitions of fast contractions ”; ECT = ”every contraction timed”, monitoring contractions). It was adopted a time of ten-minute rest between assessments. One of the examiners repeated the assessment 7-10 days from the first meeting. The reproducibility of the data was analyzed using of the kappa coefficient test for ordinal data, and intraclass correlation coefficient (ICC) for numerical data. Results: Inter-examiner reproducibility was considered moderate for the items “P” (k = 0.57), “E” (ICC = 0.53) and “F” (ICC = 0.65) and low for item “R” (ICC = 0.27). Intra-examiner reproducibility was substantial for the item “P” (k = 0.62), moderate for items “E” (ICC = 0.62) and “F” (ICC = 0.55) and low for item item “R” (ICC = 0.26). Conclusion: CVM reproducibility was greater when performed by just one researcher. However, the assessment of sustained contraction and repetitions of fast and slow contractions shows equal reproducibility in the evaluations performed by one researcher at two different times, or by two researchers at one same evaluation day.

This work presents and analyzes the transition between the bench production process of a given product and the steps that lead to interest in industrial production. The theme addresses the history of acids, their importance and the reason why over time their production was rescheduled for industrial production increasing. Taking sulfuric acid and hydrochloric acid as an example, this work presents a flowchart of the preparation up to the production chain. In this context, we describe how the market reacts with the variation in supply and demand and how this defines the decision to increase production. Finally, we present a market survey using the fertilizer sector as an example to show the importance and function played by sulfuric acid in the production chain.

The Alto Huallaga Valley, rural territory of the Peruvian Andean Amazon, has been associated with long-lasting social representations that mainly relate it to drug trafficking and political violence. Despite its high historiographic detachment, this image has played an essential role in quenching the repertoires of resistance that the peasant movement has been displaying in response to the asymmetries that the republican national project has triggered in the region. After a secular abandonment and in a kind of continuity with colonial projects, the mercantile turn has been expressed here, between political messianism and exceptional languages, through a developmental discourse on population, market and territory. And it has done so throughout its four different constitutive cycles: i) colonization projects, ii) the cocalization of its economy, iii) the armed conflict and iv) the policies of the so-called "alternative development". This study, halfway between oral history and ethnographic work, eclectic from the methodological point of view, aims to reconstruct, in its complexity, the social history of Alto Huallaga; critically contrasting the official account with the experiences of the peasant sectors that express the social impact and the limits of the modernizing project. Likewise, it seeks to enhance a ruralistic, diachronic and subordinate perspective that replaces the centrality that until today the security dimension of the conflict have deserved. Finally, it is hoped to contribute to rethinking the historical fabric of contemporary Peruvian society, without losing the perspective of the subjects located on its margins.

Introduction: In recent years, the epidemiological picture has shown that chronic non-communicable diseases are increasingly prevalent. Consequently, there is an increase in the use of health services, which causes greater expenses for the public health system. Offering health promotion actions in Primary Health Care is considered an effective strategy for healthy aging. Thus, participation in these actions can have an economic impact for users and the public health system. Objective: To evaluate the relationship between health promotion actions offered in Primary Care and the use of health services in the city of São Carlos, SP. Methods: It was a longitudinal and retrospective research which found health promotion actions in all health units in the municipality and analyzed the medical records and attendance records of the participants in the actions, in order to verify how they used the health network at the primary level, compared to those who did not participate, with a sample of 496 people. Number of visits, reasons for seeking service, professional responsible for the service, number of tests and number of medications were analyzed. The study followed all ethical aspects of research. Descriptive analyzes and intergroup comparison were performed using the statistical package Software Statistical Package for the Social Science (SPSS) considering the value of p ≤0.05, with the Mann Whitney Test for comparison between groups. Results: Of the 28 units analyzed, 71% had health promotion actions, divided into two categories:a) supervised body/manual activities (40,6%), and b) health education activities (59,4%). The average age of the participating group was 60,6 years (SD±13,1) and the non participating group was 60,4 years (SD±13,0). Of the 3252 consultations analyzed, there was a statistically significant difference between the groups for the variables number of visits, number of medications and number of tests. Conclusion: Individuals who participated in health promotion actions used the health service more due the strengthening of the bond with the health unit, promoted through participation in the actions, which positively influenced the adherence of recommendations for maintaining health and disease prevention by health service users.

Both hemispheres of the human brain, left and right, are separated by a fissure called interhemispheric (IHF), which is commonly shaped by a geometric plane, known as midsagittal plane (MSP). However, despite the name, the MSP is not always plane, once the brain is not perfectly symmetric. The detection of the MSP in human brain images is an essential task to segment the brain hemispheres. Studies suggest that abnormal values of asymmetrical brain may be related to traumas and neurological diseases. Through the years, various computer methods were proposed to detect MSP in an automated way, nonetheless the main methods that were found in literature focus on the detection of a plan, imposing such a geometric restriction on IHF. This work proposes a new automatic computational technique for the detection of a median sagittal surface (SSM) in magnetic resonance (MR) images for application in the analysis of asymmetries between cerebral hemispheres. The proposed method uses a MSP as guidance to the definition of an region of interest (ROI) that potentially contains an IHF. The RM 3D image is decomposed in 2D slices, which are processed, filtered and piled to form an MSS. Based on the results obtained, it appears that the proposed method enables a higher precision when getting the volumetric measures and therefore in the calculation of brain asymmetries. The MSS precision is evaluated comparing the left and right hemispheres segmented from the detected MSS, with the sketches handmade by two specialists.

Despite the devastation to which it was subjected, Atlantic Forest is still home to very high levels of biological diversity and endemism. From Callitrichidae family, the endangered buffy-tufted-ear marmoset (Callithrix aurita É. Geoffroy, 1812) is endemic to the Atlantic Forest of southeastern Brazil and is the least known. Its restricted distribution, the destruction of its habitat and competition with invasive species, have corroborated the population decline, increasing the risk of extinction of the species. In view of this scenario, this work aimed to collect data in situ to analyze the current situation of the groups of buffy-tufted-ear marmoset, evaluating their distribution, estimating density and population abundance in a remnant of seasonal semideciduous forest in Serra do Japi, in the municipality of Cabreúva-SP. We sampled four transects that totaled 17,6 linear km. In each transect, a division of consecutive points was established every 200 m, totaling 81 sample points, where the species' vocalization was reproduced with the use of playback. Once the presence of animals was detected, the location (GPS), the estimated distance from the observation point and the number of individuals in the group were recorded. Data collection was carried out using the monitoring method throughout the year, from June 2018 to June 2019, and data were twice a month collected. During the 13 months of monitoring 415,4 km were covered and 15 groups of buffy-tufted-ear marmoset were identified, among them, two presented hybrid individuals. It was calculated a density of 1,06 groups/km² (7,6 ind./km²) and an abundance of 4.6 groups/10 km. The groups were sampled in almost the entire length of the transects and the average number of individuals sighted was 7,2 ± 1,8 individuals/group (± SD; N = 191). These values when compared to the literature are relatively high, indicating this protection area is an important region for the conservation of the species. This is a pioneering work to present data of population estimates of buffy-tufted-ear marmoset inhabiting Serra do Japi. Despite the presence of groups in the area, future studies monitoring these populations are essential, since they are subject to several threats (loss and fragmentation of habitat, invasive species, etc.).

The advancement of new digital technologies has driven organizations to adapt their strategies and businesses. In this scenario, the present study aimed to verify how a company located in Brazil has adapted its business to the process of digital transformation. To this end, a qualitative research approach was used, and a case study was conducted with a large manufacturing company. The data were collected through interviews, documents, and direct observation. The data analysis allowed to verify: (a) a clear need for transition and changes for industry 4.0 due to the market demand; (b) evidence of the implementation and adoption of technologies such as internet of things, cloud computing, artificial intelligence, and data mining; (c) practices and changes in the organizational environment resulting from digital transformation, such as the creation of new areas dedicated to digital transformation, stimulating innovation and open communication, holding workshops, events, training, collaboration with external partners and benchmarking; and (d), finally, the existence of barriers as financial, knowledge of technologies, support from leadership and organizational culture. At this point, it was found that the necessary change for digital transformation in companies goes far beyond technological issues or new work tools. The basis for transforming processes, actions, and operating mode is mainly in the mindset of employees and leadership. This work brings theoretical contributions, by approaching a topic that is still little explored in the Brazilian context and adding evidence to the literature, and managerial ones for providing insights and clarifying practices to managers.

Proteins are macro-molecules responsible for virtually every task necessary for the maintenance of cells, having a fundamental role in the behavior and regulation of organisms. Advances in the area of Molecular Biology have allowed an almost complete listing of the proteins that make up the organisms. However, there are a large number of proteins whose function is still unknown, opening space for a new research focus in Molecular Biology. Usually, protein function prediction is performed using homology-based Bioinformatic tools, comparing a sequence with a database with many sequences belonging to previously known functions. This is a limited strategy, since it ignores the sequences' biochemical properties, and also the hierarchical relationships that may exist between the different classes. In the literature, the use of Machine Learning for the protein function prediction has shown to be promising, obtaining significant advances regarding the use of homology and other methods. Making use of Machine Learning, it is possible to model the protein function prediction problem as a Hierarchical Multi-label Classification (HMC) problem, due to the fact that protein functions are hierarchically organized and that they can occur simultaneously. This project proposes modeling the protein function prediction task as a Hierarchical Multi-label Classification problem through interaction data. Interaction data are characterized by two sets of objects, each described by their own set of features, which makes it possible to predict the interactions between two instances. In particular, we adapt the "Predictive Bi-Clustering Tree" (PBCT) method to HMC tasks. Our experiments demonstrate that PBCT-HMC is competitive to the state-of-art competitor.

In the commercial sphere, attempts at fraud and counterfeiting have caused several problems for manufacturers and the consumer market. In view of this scenario, in order to promote greater reliability and security in commercial transactions, several techniques are being used to verify the authenticity of physical products. Among them, the most used are QR Codes (Quick Response Code), holographic stamps and RFID (Radio Frequency Identification). In this work, a product authentication system that uses the visual encryption developed by Naor and Shamir is proposed. This system uses two computationally generated masks that when overlapped allow visual authentication without the need for any computational processing by the customer. With visual encryption, this authentication system was proposed by Cicareli in submitted work .

Desde o surgimento da definição de superfícies parametrizadas, foi questionado sobre suas propriedades que independem da parametrização. Propriedades essas que caracterizam objetivamente a geometria dessa família facilitando muito a sua compreensão. No século 19, com o aperfeiçoamento da geometria semi-Riemanniana feito por Bernhard Riemann e Carl Friedrich Gauss, foi introduzida na literatura a noção das curvaturas média (H), gaussiana (K) e principais (k₁,...,k_{n-1}) onde n-1 é a dimensão da superfície. Essas noções independem da parametrização e são fundamentais na caracterização de uma superfície. O objetivo desse trabalho é o estudo e a caracterização de superfícies de Weingarten em espaços não triviais como , por exemplo, o espaço hiperbólico H³ , o espaço lorentziano L³ e o hiperboloide I₃ contido no espaço de Lorentz-Minkowski L⁴. Definimos uma superfície de Weingarten (de dimensão 2) como uma superfície dotada de uma relação entre suas curvaturas principais k₁ e k₂ dada por W(k₁,k₂)=0. Notemos que essa família generaliza exemplos clássicos de superfícies já estudadas atualmente, como as superfícies mínimas, onde W(k₁,k₂)=k₁+k₂ . Esse trabalho terá um enfoque especial no caso em que W(k₁,k₂)=k₁²+k₂²+C, onde C é uma constante real. Que é um caso não linear, um pouco distante da literatura atual. O segundo capítulo introduz alguns pré-requisitos de geometria Semi-Riemanniana, que serão admitidos como verdade de modo a dar suporte para todos cálculos realizados nos capítulos seguintes. O terceiro capítulo será uma breve introdução ao caso mais natural possível, onde as superfícies serão imersas no espaço euclidiano R³. O capítulo quatro englobará quase toda a teoria do primeiro capítulo aplicada no espaço hiperbólico, com enfoque nas imersões isométricas de hipersuperfícies e exemplos. O quinto capítulo abrangerá a mesma teoria do primeiro capítulo, agora aplicada no espaço de Lorentz-Minkowiski. Já no sexto capítulo, falaremos de um subconjunto do L⁴ que se relaciona com o H³: O hiperboloide I₃, com muito enfoque, novamente, na teoria de imersões isométricas de hipersuperfícies. Nesse capítulo vamos relacionar os três modelos hiperbólicos de modo a facilitar determinado problema, que talvez possa ser complexo em um determinado modelo mas não em outro. Por fim, vamos estudar o problema de superfícies de Weingarten numa dimensão maior, tratando novamente de um caso bem natural: Superfícies dentro do ℝ⁴.

The current Internet architecture has been the same since the time of its creation and has undergone increments and modifications in its protocols to meet new demands that have been arising over time. As the resolution of all these issues is not easily solved with the addition of new functionalities or architectural modifications, proposals for the development of new Internet architectures started around the world. With several new Internet architectures being proposed, choosing a new Internet architecture to replace the current one becomes an extremely complex task. Thus, the emergence of a heterogeneous environment composed of multiple Internet architectures that allows the coexistence of new Future Internet Architectures, through the current network infrastructure, becomes a viable solution. Thereby, this work presents a proposal that enables the coexistence of multiple Internet Architectures on the current network infrastructure, in order to enable communication between entities of the same Internet architecture, enabling the emergence of the heterogeneous environment composed of multiple Internet architectures. To this end, this proposal defines the creation and joint operation of programmable switches implemented in P4 language, specific controllers for each Internet architecture supported by the proposal and a Control Protocol used to standardize the exchange of control messages, regardless of the architecture, thus enabling the exchange of traffic between entities of the same Future Internet Architectures, through the existing network infrastructure. To demonstrate this proposal, a proof of concept was implemented in a virtualized environment, where the Future Internet Architectures ETArch and NovaGenesis were chosen to be initially supported by the solution, as well as the IPv4 protocol. Finally, the proof of concept validation and tests related to the processing time of data and control packets were performed, where the independence of processing time was observed in relation to the size of a package of such an architecture as well as other performance information.

INTRODUCTION: Primary care workers assume an important role in terms of the multiplication of health information, however the overload in their work environment makes disease prevention and health promotion programs that include them indispensable. OBJECTIVE: To evaluate the perception of effectiveness and feasibility of a program to support lifestyle changes for health professionals in Primary Care. METHODS: This is a qualitative study carried out in the city of São Carlos, SP, part of a randomized clinical study carried out in the Basic Health Units (UBS) and Family Health Units (USF) in the municipality. The program consists of an intervention with six meetings of approximately 40 minutes, the first being a pre-assessment, the four consecutive meetings addressing themes that pertain to behavior change, such as: Tips and Benefits; Barriers; Relapses and Saboteurs' Thoughts, using different strategies in order to support the change in behavior of the workers involved, and the sixth meeting consisted of a post evaluation and qualitative interview. Twenty health professionals were interviewed, aged over 18 years, who reached 85% of frequency in the program offered. A semi-structured interview was conducted at the end of the program's participation, by trained interviewers, in which the individuals answered, according to their opinion, what their level of satisfaction with the program was, how effective it was, what their suggestions for improvement about it and about the knowledge acquired with the program. The interviews took place at his workplace and were recorded using the interviewer's smartphone recorder, with the interviewee's consent. The data were analyzed through content analysis by Bardin and Minayo, with categorization of the main domains identified in the participants' statements. RESULTS: From the workers 'reports, it was identified that the program is perceived as viable, of quality, effective and that it contributes to the improvement of the participants' lifestyle. CONCLUSION: The behavior change program was effective and feasible in the perception of primary care health professionals.

The object of the present research, the disciplining of the babies' bodies in the daycare center, emerged during the internship experiences in a classroom with two-year-old babies and also from the professional work as a professional in Early Childhood Education. In those contexts were observed disciplinary actions and strict control of bodies and movements of babies by educators. So the research question-problem was born: What are the consequences in the life of the young child of disciplining the bodies in the nursery? The work is divided into three chapters. The first is the Memorial, which gathers reflections on school life and field experiences at school that led to the study of the subject in question. The second chapter presents a methodology that configures a qualitative research, of bibliographic character complemented by the analysis of some field experiences. The third chapter presents the theoretical framework and reflections on school routine situations that were marked by discipline, control of babies' bodies. The results point to losses for children in relation to their integral development as a consequence of the exacerbation of the schooling of young children, with impositions of rigid postures for their bodies and prohibition of playing, the most important activity in this age group, through which she learns and develops.

The excessive consumption of these drugs can cause the development of superbugs capable of resisting treatments in humans, in addition to environmental consequences. Among the alternatives used, fibers obtained by electrospinning stand out as a simple and low cost strategy, increasing the bioavailability of an active principle at an infected site, for example, reaching therapeutic levels with a single dose. Thus, the objective of this work was to obtain fiber polylactic acid: starch: clay for controlled / prolonged drug release. The fibers were produced using electrospinning technique in which four different systems were developed: polylactic acid; polylactic acid and starch; polylactic, starch and laponite; polylactic acid, starch and montmorillonite. However, for each system developed, benzathine and sodium cloxacillin were tested. Bactericidal tests were carried out with all samples against the bacteria S. aureus and E. coli. In addition, mechanical analysis of the developed systems was carried out. The release tests were carried out in buffered pH 7 solutions and the drugs were quantified with the aid of an ultraviolet-visible spectrophotometer. The results indicated that the fibers of the polylactic acid starch and montmorillonite system showed higher values of tension and deformation, approximately 4 times, when compared to the polylactic acid fibers. In the release tests, controlled/prolonged release profiles were observed, by adding clays, laponite and montmorillonite, which were adjusted by the Korsmeyer-Peppas model. In the other systems, burst release profiles were observed. Microbiological tests for these systems, using benzathine and sodium cloxacillin, have shown bactericidal activity against the bacterium S. aureus. Therefore, systems that contain clays are promising for application involving the release of cloxacillins, especially those that require dosage, whose concentration remains for a long time in the therapeutic range of this medication

The object of this work was born from my experiences as an educator in the early years of elementary school in a private school in the city of Sorocaba / SP. Such experiences provoked a rescue of my memories as a player in theatrical experiences and impelled me to look for other languages to be worked in the school context. Therefore, this work represents my journey as a researcher of my own practice. The research aimed to inquire about the place of movement, play and theater games in Elementary School, observing the spaces / times granted to them and the possibilities of teaching performance through them. It is constituted as a qualitative research, of bibliographic character with field study. The main author studied is Viola Spolin (1987), creator of the theater games methodology. As a way of enriching the reflections, the work is also built based on Karine Ramaldi (2015; 2017), Robson Camargo (2017), Lucia Lombardi (2010; 2011), Joaquim Gama (2010), Alessandra Ancona de Faria (2002, 2010). On playing in childhood, the work is based on research by Tizuko Morchida Kishimoto, Gilles Brougère and Marcos Garcia Neira who study playing as a children's play culture. The work is divided into four chapters. The first chapter presents my memorial as a reflection on the paths that led me to the object of research. The second chapter presents the methodological procedures used, including the bibliographic survey. Chapter III, entitled “Theoretical framework”, presents the references that support the work and the reflection, the crossing of studies carried out on the subject and the definitions of concepts. Chapter IV deals with the analysis of experiences, experiences and reflections during my period as a teacher in elementary school that motivated the work, reflecting supported by the authors and by the questions that each of them generated in me. The results reveal that school spaces focused on art need to be occupied in order for movements and recreations to happen from within - from each player - and from outside - in every school environment.
