This research aims to analyze the relationship between historical Syrian migration and the arrival of Syrian refugee families to Itapira, a city in the countryside of São Paulo, in order to understand the similarities and continuities in the migrant experience of a Syrian extended family that in 1945 had a relative who came to live in the country. After her, due to the impacts of the Syrian war, her brother and nephews came to take refuge in this same city, starting in 2011, and were also supported by her. Using ethnographic observation, statistical data and bibliographic references from Anthropology, Sociology, History and Demography on international migration and refuge in the state of São Paulo and Brazil, between 1880 and 2016, it was verified, from the trajectories of the interlocutors participating in the research, that the similarities and continuities in the integration process of refugee families are similar to those experienced by the aunt. In general, they are related to the difficulty of communication due to the language, the prejudiced view that the receiving society had towards them, but also the opportunities to live and have a dignified life in foreign territory after years established in Brazil. In addition, it also shows that migratory categories homogenize and frame refugees in a process that removes their identity, peculiarities and diverse possibilities and modes of existence that cooperate with the processes of invisibilization for the maintenance of social vulnerability and withdrawal of rights. In addition to adaptation, the trajectory of religious and conflict refugees is marked by memories of the violence they have suffered and in a way keeps them connected, or not, with their homeland.

Introduction: lay people facing and Extra-Hospital Cardiorespiratory Arrest may panic and discredit themselves, delaying care for the victim. Therefore, a simulated and repetitive training experience, during which the apprentice can practice his skills without causing harm to the victim, can be na opportunity to acquire knowledge and skills. Objective: To evaluate the influence of training using Rapid Cycle Deliberate Practice in university students facing a situation of Cardiorespiratory Arrest and performing Basic Life Support with the use of the Automated External Defibrillator. Methodology: Cross-sectional and quasi-experimental study of the type before and after a single group intervention, developed at the Health Simulation Unit of the Federal University of São Carlos, with a sample composed of 29 lay undergraduate students in the subject of the study. Data collection took place from August to December 2022, after approval of the research by the Human Research Ethics Committee under number CAAE: 50590821.0.0000.5504. Theoretical training and simulated training were carried out with the use of Rapid Cycle Deliberate Practice for teaching Basic Life Support and the use of Automated External Defibrillator. Knowledge was evaluated pre and post training through the instrument built with theoretical concepts on the subject, technical performance and practical performance through the evaluation guide in Rapid Cycle Deliberate Practice and, finally, self-confidence, pre and post training through the Self-Confidence Scale for intervention in emergencies. Descriptive analyzes were performed for each item, the other statistical analyzes were performed using Poisson regression models, ANOVA models and linear regression models. Results: The profileof the participants was: female (75.86%), between 21 and 22 years old (34.47%), the majority (79.31%) belonging to courses in the health area and 6 (20, 69%) reported having the habit of accessing materials related to the theme. As for the knowledge and self-confidence test, in general, there was an improvement in the scores on all items in the post-test. Regarding the performance of the participants, when comparing the times between the groups, those participants who acted first in the scene obtained significantly greater times in stage 1 and 3, while in relation to the number of repetitions, only in stage 3 there was relevance in the comparison between groups, with two more repetitions in the “not first of the day” group. Conclusion: There was a significant increase in knowledge and self-confidence after training with the use of Deliberate Practice in Rapid Cycles. As for performance, the participants' total performance time was greater in stage 2 and 3, which may be related to the greater complexity of the scenes; while the need for the number of repetitions in the three seasons was similar. The academic area and access to education influenced the time of work in this sample; and the relationship between being the first of the day or not during the performance, impacted the number of repetitions and the total time of stage 2.

Water has a direct influence on health, quality of life and human development. Most of the infectious disease burden in developing countries refer to water contamination by pathogenic microorganisms, emphasizing the importance of proper treatment, even in point-of-use solutions. Ultraviolet C radiation (UV-C) as a germicide has been studied since the beginning of the 20th century. Microorganism inactivation by UV-C is caused by alterations in DNA that lead to the formation of the pyrimidine dimer. In this study, the performance of a UV-C reactor coupled to a storage tank was evaluated, aiming to disinfect water artificially seeded with Escherichia coli. The prototype consisted of a closed-circuit system, with continuous flow, able to operate with different storage volumes. In the system, water circulates by mechanic agitation impelled by two peristaltic pumps. The UV-C irradiation source was based on 6 units of 30 W germicide lamps. In this study, operation was investigated in different volumes (1, 2, 5, and 15 L), under constant flow rate of 1 L/min of fluid exposure to light, for 60 min maximum. Finally, an analysis was carried out considering the empirical relationships found, to allow extrapolate results aiming to determine the required time to remove a given concentration of E. coli in different volumes of water. The effect of germicidal lamps on microbial inactivation showed that there is a bacterial reduction in different volumes, since in the experiments carried out the initial concentration of E. coli in logarithmic scale in volumes 1, 2, 5 and 15 L were 7.13, 5.74 , 6.10 and 5.78 log CFU/mL, respectively. The analysis shows us that in volumes 1, 2, 5 and 15 L there was a reduction in E. coli survival of 6.24, 4.03, 2.78 and 1.64 log CFU/mL, respectively.

There are several actions in which we strive to make cities viable and sustainable, pursuing to be an alternative to the actual problems in the daily life of urbanization. In this dissertation, one of these alternatives is presented, urban agriculture (UA), which aggregates diversified practices aimed at self-consumption and/or sale to urban local markets. It occurs in distinct areas, in terms of size, location and land ownership, whether public or private. This paper focuses on pointing out that UA practices happen informally, spontaneously and in different localities. UA techniques such as soil management, vegetable and animal farming which have been incorporated into the concept are not new in the urban environment, but in the academic and institutional environment this subject is a novelty. Thereby, the objective of this work is: To analyze how the Agroforestry System Odara becomes a mechanism for the development of ecological subjects through the transformation of urban space. The data were collected through semi-structured interviews carried out with the Odara Group, residents at the surroundings of the Odara AFS and, the public power of the municipality of Itapetininga. With this dissertation, it is concluded that urban agriculture plays an important role in shaping an ecological subject, contributing to awareness and social transformation regarding environmental issues.

The aim of this study was to evaluate the effect of using treated domestic sewage from the Sewage Treatment Station (ETE) at CCA/UFSCar – Araras as an alternative source to commercial nutrient solutions in the cultivation of anthurium (Anthurium andraeanum cv. Sumi), using 3 treatments (TA: drinking water + mineral fertilizers; TR: reuse water; TRA: reuse water + supplementation with mineral fertilizers), through the collection of data on the total chlorophyll index and biometric measurements, namely stem size, of the largest leaf, spadix, spathe length, plant height, number of flowers and leaves. The experimental design was in randomized blocks, with four replications, and the data were submitted to analysis of variance, and determined by the F test, the means were compared by the Tukey test. The use of reuse water (RT) showed lower values in the total chlorophyll index, and its biometric measurements were lower when compared to the other treatments. The TRA treatment did not present a significant difference in the biometric measurements, when compared with the TA treatment, but it presented a lower chlorophyll index when compared to the same. In this way, the use of reuse water complemented with mineral fertilizers can be a viable alternative option for the cultivation of anthurium.

In this work, we investigate the existence of positive stationary solutions of the Kirchhoff equations in a limited domain, an inhomogeneous spatial coefficient and a function of first order terms with growth up to the natural. Unlike the coercive cases where the operator has a suitable lower-order term or a Dirichlet boundary condition, in the case of a refreshing Neumann boundary condition, a lack of coercivity in the Kirchhoff term occurs. In this last scenario, we prove an existence result that plays the role of a sub-supersolution principle for positive solutions of. As an application, examples are provided that show the existence of positive stationary solutions satisfying the Neumann boundary condition. To overcome the lack of coercivity we combine monotonicity and truncation techniques, with the theory of elliptic regularity, in order to construct parametric approximate problems that are coercive, and whose solutions converge, as the parameter tends to zero, to a solution.

The teacher is a fundamental figure in the learning process of social skills in the School context, in articulation with academic learning. This articulation involves teaching strategies that require, in addition to mastering the academic content, a good repertoire of social educational skills from the teacher and their continued training in this direction. For this, guidance and support through specialized advisory is essential. The present study focuses on the final stage (module 4) of a process of continuing education for teachers, whose objective was the construction, implementation and evaluation of virtual advisory for teachers to promote socioemotional development at school. To this end, module 4 included making resources and guidance sheets available in a virtual environment and advising teachers to develop, apply and evaluate a social skills program with their class of students. This thesis is composed of three chapters. Chapter I describes the process of analyzing materials and preparing guidance sheets for Elementary School teachers to promote socio-emotional development in the classroom, as well as evaluating the acceptability and feasibility of using these sheets from the teachers' perspective. Sixty-nine resources were selected and guidance sheets were created to be used by the teachers participating in module 4. Based on the data, the acceptability and positive evaluation of the teachers regarding the application of the resources with the students was noted. In Chapter II, the process and results of the virtual assistance offered to three Elementary School teachers are evaluated. The results, analyzed qualitatively and quantitatively, showed effectiveness, acceptability and viability of the online advisory process in the performance of teachers and promotion of students' socio-emotional development. Finally, Chapter III aimed to evaluate the impact of this program, guided by the advisory process, on: (a) the repertoire of social skills and (b) academic performance of students and (c) on the HSE of the three teacher’s participants. Tools from the virtual environment were used to provide resources and guidance sheets, record teaching plans and application reports, as well as self-assessment by teachers and assessment by the advisory staff. Students' assessment instruments were also applied in relation to the HS repertoire, behavior problems and academic competence. In general, positive changes were identified in the social and academic performance of the students and the social educational skills of the teachers. Furthermore, the participants made positive evaluations of the program. The set of studies suggests the viability of continuing education for teachers in social skills and social educational skills, with specialized support, in the EaD format. Positive aspects of the work, social and scientific contributions, as well as limitations and aspects to be improved are discussed

Global concern around sustainable development has increased and production practices that can contribute to this have gained prominence – with reverse logistics (RL) being one of these. However, the topic is still emerging and requires new efforts. The definition of which contributions reverse logistics can bring to sustainability is still inexact. The research aim is to extend the understanding of the sustainable impacts that RL can generate economically, environmentally and socially and to define which SDGs (Sustainable Development Goals) are the most impacted by RL adoption. In addition, it is intended to contribute to the production of knowledge related to RL and sustainability in its three dimensions – where there is a lack of studies –; demonstrate to companies interested in increasing their adherence to the global SDG pact how the adoption of RL can benefit them; identify the main impacts of RL for sustainable development and elucidate how RL adoption can help the achievement of the SDGs. For these purposes, the research will make use of: (i) a systematic literature review in order to gather the empirical evidence of RL impacts on sustainability, (ii) expert elicitation through the IDEA protocol to evaluate the relation between RL and the SDGs and (iii) VIKOR to the analysis and to define which SDGs are the most impacted by the adoption of RL practices. It was found in literature that: the environmental pillar of sustainability is the one with more impacts reported; the social pillar still has minimum impacts reported – even with the great social contributions pointed for human welfare – and the RL impact most cited in literature was “improve profit and cost savings”. After the analysis in the second article presented in this dissertation, it was found that SDG 12 has the greatest contribution from RL adoption and SDG 1 is the one which has its accomplishment least driven by RL. At the end, instructions for further research are given.

Given the important role of fashion in the construction of social identities and the actual relevance of digital media, this dissertation aims to analyze how gender subjectivation processes take shape through fast-fashion discourses regarding digital influencers. Characterized by technological as well as social transformations, the digital age made it possible to create personal or corporative accounts in digital platforms. Consequently, corporate accounts started to post fashion images which enabled interaction through “comments” and “likes”. In this way, any personal account interested could engage interaction. Hence, the digital age became responsible for a major shift on gender and fashion related studies in the Sociology field, since it enabled different forms of interaction, sociability and subjectivity. Before the digital age, it was actually possible for some researchers to question to what extent traditional media really got through its public, since they barely seemed to be paying attention (given that they didn´t have the habit of commenting those contents). A completely different scenario seems to be on display nowadays, since the hundreds and thousands of likes and comments show an exact opposite behavior from that of the public back then. This certainly challenges the very questions some of these researchers posed before. Given this shift, in order to investigate its impact on the analysis proposed here initially, this dissertation takes @cea_brasil as its field site. More specifically, there were selected posts where, majorly, BBB21 participants were the main subjects. Methodologically, an incursion inspired by digital ethnography was conducted. Techniques such as participant and non-participant observation as well as semi-structured interviews were used. The interviews were conducted with those who either commented or liked the posts @cea_brasil. As theoretical references, there were taken into account authors who work from a foucaultian viewpoint, such as Judith Butler and Manuel Castells. As main results, the subjectivation processes were comprehended to destabilize the heterosexual power matrix from within the many tensions they dwell.

The road freight transportation activity is highly relevant nowadays, both financially and socially, since human survival depends on the resources transported by road freight transportation. However, cargo transport also has negative impacts, mainly due to the high emission of polluting gases, congestion and traffic accidents. Thus, it is essential to adopt technologies to make road freight transportation more efficient from an operational point of view and make it more sustainable. Knowing that technologies play an important role in road freight transportation, it was identified in the literature that technologies enable specific capabilities for road freight transportation. Thus, the main objective of this thesis is to study the role of capabilities enabled by technology in the road freight transportation system. To achieve these goals, three basic steps are taken. The first stage comprises a multimethod study to identify the capabilities enabled by technology in the road freight transportation system and verify the technological readiness level (TRL) of these capabilities based on secondary data. At this stage, 32 capabilities enabled by technology in the road freight transportation system were identified and organized into six categories (transport infrastructure; transport information; transport management; transport operation; transport monitoring; transport sustainability). In the second stage, the cause-and-effect associations between the resources enabled by the technologies for managing road freight transportation operations were analyzed. For the study of capabilities related to operations management, we used a mixed method approach based on three basic steps: identification and validation of technology-enabled data visibility capabilities; cause and effect association analysis; construction of technology-enabled capabilities framework for data visibility in road freight operations. As a result of the study, a framework was built with 11 technology-enabled capabilities for data visibility in road freight transportation operations. In the third stage of the study, the cause-and-effect associations between technology-enabled data visibility features in road freight transportation operations were analyzed. Basically, the same research method as in the second stage was used in this third stage of the study. The result of this step is a framework with 12 technology-enabled capabilities related to road freight transportation management, and a framework for classifying these capabilities was proposed. Finally, based on the analysis of the three stages of the study, a final conceptual model was proposed, systematizing the results obtained. This conceptual model presents three basic steps: (1) identification of capabilities related to the considered performance factor; (2) identification of which capabilities should be prioritized; (3) identification of which technologies should be prioritized.

This research aims to analyze the visual arts known as "contemporary Afro-Brazilian" through the prism of the African Diaspora. Starting from the following question: How does contemporary Afro-Brazilian art represent the demands of populations constructed as black? I analyzed the exhibition design of the PretAtitude exhibition: Emergencies, Insurgencies, and Affirmations in Contemporary Afro-Brazilian Art, curated by artist Claudinei Roberto da Silva. In this analysis, I sought to highlight the relationship between the Afro-diasporic aesthetics of part of the itinerant exhibitions and their political agency. The objectives were to investigate the catalogs, identifying techniques, themes, and studying the present artists to better understand the aesthetics of each one. Through interviews, I sought to identify how the curator chose the title and what he is referring to with the terms that guide the exhibition. The hypothesis is that, from an artistic perspective and in the exhibition's agenda, we see how Afro-diasporic aesthetics and political agency are connected in a movement to reposition the place of Africa and the contributions of the racialized black population to human history.

Body Centered Cubic (BCC) multicomponent alloys have gained attention in the research of materials for H2 storage. These alloys have the potential to optimize H2 storage properties via compositional control. However, the investigation of the various storage properties is still scarce for these alloys, and the comprehension of hydrogenation reactions is in the early stages. Based on these challenges, this doctoral project aimed to: 1) Investigate the effect of the addition of non-hydride forming elements (M = Cr, Co and Ni) on the hydrogen storage properties and microstructure of multicomponent alloys of the Ti-V-Nb-M system; 2) Identify the formation of possible hydrides and structural changes caused by absorption/desorption reactions; 3) Design alloys of the Ti-V-Nb-M system with different storage properties for various applications. The hydrogen storage experiments, such as pressure-composition-temperature (PCT) diagrams, kinetics of absorption and partial hydrogenation, combined with detailed structural characterizations, allowed us to identify that the alloys absorb H initially forming an intermediate BCC hydride followed by the formation of a face-centered cubic (CFC) hydride reaching storage capacities of 2.4-3.2 wt%. The addition of non-hydride forming elements has been shown to contribute to the formation of secondary phases such as Laves C15 phase. Additionally, it showed influence on the thermodynamics of the CFC hydride formation (increasing the content of these elements results in higher equilibrium pressures for H absorption/desorption). The results also indicated that this influence is related to the valence electron concentration (VEC) of the alloys. Finally, computational thermodynamic tools proved to be excellent tools for the design of alloys with excellent storage properties. These tools allowed the obtention of the Ti11V30Nb28Cr31 BCC alloy with reversible absorption/desorption capacity of 1.7 wt%. of hydrogen at room temperature.

Imbalanced data refers to a dataset where one class has significantly fewer observations than the other class. This can lead to poor performance of both machine learning algorithms and statistical models, since most of these tools assume that the data has the same proportion of observations in both categories. To deal with this challenge, several authors suggest the use of asymmetric link functions in binary regression, instead of the well-known symmetric link functions: logit and probit. Thus, it is possible not only to improve the predictive performance of the model, but also to reduce the bias in the estimation of parameters and probabilities. This is a solution that generates probabilistic models, which excel in decision-making compared to those that simply assign a single class without considering the associated probability. Therefore, this work aims to present new asymmetric link functions generated from the transformations of the Lomax distribution. These functions include the Double Lomax (DLomax), Power Double Lomax (PDLomax), and Reverse Power Double Lomax (RPDLomax) distributions. The proposed functions have proven asymmetry and can be easily implemented in statistical softwares. In addition, the simulation study indicates that these functions can perform better than logistic regression in various imbalanced classification scenarios. They also proved to be promising in modeling real-world datasets, as in this work we obtained better results than classic link functions in two applications.

This research started with the planning and execution of Didactic Sequences in the area of Science, using the construction of a Conceptual Map as a didactic resource for the development of scientific literacy. The activities were carried out by students in the 4th year of Elementary School I, in a post-pandemic reality where relationships were still apathetic, based on their experimental experiences, the resocialization process, developed in a municipal public school in the city of Sorocaba. The Didactic Sequences (SDs) elaborated started from the pedagogical proposals referring to the 4th year, thus, the Water theme was the content adopted following the following strategies: classes and activities on the school Blog, presentation of seminars, carrying out experiments and construction of Conceptual Maps . The research was supported by the theoretical assumptions of Sasseron and Carvalho, Ausubel and Novak, which point to the need to re-dimension the scientific work at school, based on the knowledge of the world that students already have, based on Meaningful Learning through the construction Conceptual Maps and the development of Scientific Literacy. The methodology used is part of a qualitative, descriptive and interpretative approach. For data collection, recordings of the classes were used, the debate of the members of each group and the Conceptual Maps constructed by the students, with the aim of analyzing the resocialization and the development of Scientific Literacy. The results showed that the Conceptual Maps provide an active involvement of the students in the process, showing us in their dialogues, the interaction between peers, the resocialization of each one in the school environment, thus providing learning, living together in a meaningful way, offering possibilities of advancing the exchange of knowledge and collaborating for the development of scientific literacy.

Since its inception, the field of Studies on the relations between STS envisioned understanding the development of science and technology as a human construction, which suffers interference from social, economic and political interests. Thus, we assume that the approximation of these studies with science education is oriented towards social transformation and the socio-political formation of students, which has also resulted in the implementation of discussions on socio-scientific issues (QSC) in education, as well as in the elaboration of of academic works to disseminate these research data. That said, an in-depth analysis of the literature produced is essential, with the aim of understanding the development of this field and its marks on science research and teaching in our country. For this, we used a state-of-the-knowledge survey, so that the information was compiled in two stages: 1) Complete articles published in the Annals of national events in the area (ENPEC, ENEQ, EPEF and ENEBIO) and 2 ) Complete articles published in national journals evaluated as Qualis CAPES A1, A2 and B1 (2013-2016 Quadrennial), in the teaching area. Thus, through the constitution of these data, our analyzes point to the main trends in the field of studies on QSC in Brazil: the majority of production by researchers located in the south-southeast axis, a fact that has changed over the last few years due to the expansion of universities and the creation of graduate programs in the north, northeast and midwest regions of the country. As the main silencings found, we highlight the absence of references for the delimitation of the teaching methodology used, as well as with respect to what training is aimed at with the inclusion of QSC in teaching. Finally, from the analysis of these documents, we seek to contribute to a greater understanding of studies on QSC in Brazil, as well as deepen discussions on trends, silencing and emerging themes of this field of studies in our country.

Brazil is increasingly gaining global prominence in the generation of bioenergy, mainly in the production of ethanol, some residues result from this process, such as vinasse. Because it contains high levels of organic matter, vinasse has been used as fertigation for plant cultivation. However, its application has a high polluting potential when handled incorrectly and can contaminate the soil, surface and groundwater. This study carried out a comparative study of the environmental impact of the application of vinasse in the soil. The study analyzed the evolution of vinasse biodegradation using respirometry and the environmental toxicity levels of in natura and concentrated vinasse to L. sativa. It also verified the soil chemical changes influenced by biofertigation and used Principal Component Analysis in the statistics. Evidence was observed that vinasse biodegradation works well with both raw and concentrated vinasse. In addition, as a result of ecotoxicity, vinasse, when properly applied to the soil, does not harm L. sativa and improves initial plant growth.

A presidential election process can generate rational expectations of a ‘risk premium’ among investors, with a speculative bias due to political uncertainty, allowing for the occurrence of explosive behavior in stock prices. In this study, stock prices were used at 5-minute intraday intervals to identify and date episodes of rational bubbles (explosive dynamics) in the sectors of B3 (Brazilian Stock Exchange and Over-the-Counter Market) throughout the Brazilian electoral process of 2022: comprising between the 5th business day after the start of electoral propaganda (08/23/2022) until the 15th business day after the second round (11/18/2022), totaling 60 trading sessions. To this end, the Generalized Supremum Augmented Dickey-Fuller test was applied in a panel configuration (Panel GSADF), with each B3 sector being a data panel. The following question was sought to be answered: during the Brazilian electoral period of 2022, were there rational bubbles in the B3 sectors? With the Panel GSADF test methodology, it was possible to detect multiple bubble episodes in the Oil, Gas and Biofuel (2 episodes), Health (2 episodes) and Information Technology (5 episodes) sectors. November 16th presented bubble episodes in these three sectors, with the Health sector having the longest explosive behavior. The studies and results presented in this work may be useful for theoretical and empirical researchers, economic authorities and private sector agents in order to become aware of mechanisms to identify bubbles in financial markets and measure their extensions.

With the increasing population and demand for food, increasing crop productivity without expanding agricultural land is a crucial challenge. Soil chemical analysis and foliar diagnosis are important tools to ensure healthy plant development, assisting in the decision-making process for the appropriate and sustainable application of inputs, especially fertilizers, amendments, and pesticides. In this context, the LIBS technique stands out for allowing quick and multi-elemental analysis with minimal or no sample preparation. LIBS also has a wide range of configurations, with the most common being single-pulse (SP-LIBS) and double-pulse (DP-LIBS) configurations. However, analyzing data generated by LIBS is complex, requiring automation. This work presents the development of a software called LIBSsa, which automates the analysis of LIBS data to develop quantification models of macro and micronutrients in sugarcane, coffee, and soybean leaves. The software was created in Python, a widely used language in both scientific and corporate environments, mainly for being open-source and offering a wide range of scientific tools. In addition, protocols for foliar analysis with LIBS were proposed, using two sets of samples: Set 1, measured in a DP-LIBS system, and Set 2, measured in an SP-LIBS system. Promising results were obtained, where for Set 1 samples, quantification models were obtained for Ca, Mg, Mn, and P, with calibration and validation correlations above 83%, while for Set 2 samples, quantification models were obtained for Al, Cu, Fe, K, and Zn, with calibration and validation correlations above 70%. All results were obtained using LIBSsa, which proved to be intuitive and computationally efficient, in addition to having open-source code, offering a promising path for quick and accurate nutrient analysis in plants using LIBS.

Cannabis, popularly known in Brazil as "marijuana", has been used culturally by humans for millennia. It is indicated that, currently, its use is associated with several purposes: medicinal, gastronomic, industrial and social (known as "recreational", and also named as "adult use"). This research presents from a historical perspective, the social developments of the illegality of Cannabis, the cultural context of Cannabis, in addition to the industrial use and medicinal use of Cannabis. Particularities about the development of science, the characteristics of scientific communication and the development of scientific journals are discussed. This research found answers, in scientific periodicals specialized in Cannabis, regarding the status of its medicinal use. As for the method used to identify the universe to be researched, it allowed the identification of scientific journals in Ulrich's, which has an editorial scope focused on Cannabis studies, available in open access, namely: [1] Cannabis, [2] Cannabis and Cannabinoid Research, [3] Journal of Cannabis Research and [4] Medical Cannabis and Cannabinoids. In addition, it was confirmed that the pathways that characterize open access publications expand the reach of scientific communication and optimize access to the publications themselves, also amplify the social value of research, the value of funding agencies and research institutions. The reading and analysis of the keywords, title and abstract of each material allowed the identification of thematic nuclei of the documents, enabling the creation of categories of analysis according to Bardin's (1977) proposal. The following research themes were identified: treatment of pain of different origins; use of cannabinoids as substitutes for other medications; management of endometriosis; treatment for arthritis; treatment of inflammatory bowel diseases; treatment for sickle cell disease; treatment for cachexia; treatment for refractory stuttering; treatment for anxiety; medicinal use of Cannabis for COVID-19; self-medication with Cannabis; treatments for Cannabis overuse disorders; drug interactions; cannabidiol (CBD); other cannabinoids; chemical components of Cannabis and its derivatives; perioperative uses of Cannabis; consumption patterns for medicinal purposes; healthcare professionals; patients using Cannabis for medicinal purposes; studies and reviews. It is stated that the therapeutic potential of Cannabis is vast, a fact that allows the topic to assume a significant role in scientific studies soon, as well as to expand its own use in medicine.
