From the perspective of Special Education (SE), Brazilian legal provisions ensure some supports’ types for students with disabilities (SWD) in regular education systems. However, when considering Physical Education (PE) classes, which have specific conditions and different features from those of regular classrooms, it is necessary to think about who should become the professional responsible for this support. In some countries, there is a specialist teacher in Adapted Physical Education (APE), who provides support services for PE at school, however, in Brazil, this presence is still not common. Thus, this research aimed to analyze the possibilities and limits of the role of the specialist teacher in APE in inclusive contexts in Brazilian Basic Education. Its specific objectives were: 1) to identify what the educational legislation, in different governmental spheres, and the Brazilian and international academic literature, offer with regard to support services and specialized professionals aimed at SWD, in PE classes; and 2) to elaborate, develop and analyze a proposal of inclusion support services offered by the specialist teacher in APE, to the different actors involved in the inclusion process in PE classes, in a public municipal education network in the countryside of São Paulo (SP). As method, the collaborative research was selected and it involved the participation of a pair formed by a PE teacher (n=1), who met the inclusion criteria, and the researcher, who work in the same school municipal education network. For data collection, four stages were defined: I. Approximation, Communication; II. Co-planning; III. Collaborative Action, and IV. Co-evaluation, using as procedures: two interviews - initial and final; systematic observation and field diary; and as instruments their respective scripts. For data treatment, thematic analysis and three reliability criteria were adopted (intra-judge agreement, member checking, and data triangulation). As results, it was elaborated and analyzed through the collaborative action between the research participants, a proposal of inclusion support services that can be offered by the specialist teacher in APE, to the different actors involved in PE classes, establishing some general guidelines and indicating possible attributions, roles, responsibilities and strategies, directed to the Brazilian context, based on the consulting, itinerancy, and co-teaching approaches. Finally, it was verified that benefits were promoted not only to SWD, but to all students and to the research participant PE teacher, and that these services should be performed by expert teachers properly qualified with 1) pre-service teacher training in the area of PE; 2) recognized experience and performance with people with disabilities in PE classes at school and in various fields of APE; and, initially, 3) with specialization at the Stricto Sensu Graduate level, in the area of SE and/or APE. In conclusion, the urgency for creating independent Stricto Sensu Graduation Programs in APE and the need for implementation of specialist teachers in APE, as well as the insertion of this professional in regular education networks, was identified, so that they belong to the support networks and are offered the specialized support services needed to the specifics of PE classes.

The use of renewable energies, such as solar and wind energy, reduces carbon dioxide emissions into the atmosphere and enables the implementation of distributed microgeneration and minigeneration systems in homes, businesses and industries. However, it is only possible to integrate renewable energy sources with the electrical grid with the use of inverters, which are devices based on power electronics. Thus, this research presents an analysis of the implementation of a photovoltaic system in a commercial establishment, operating as distributed microgeneration. To carry out the analyses, the main agents that regulate the Brazilian electricity sector and the regulations that determine the minimum and mandatory requirements for connecting power inverters to the electrical distribution network were studied. To understand the operation of the photovoltaic generation system, a study was carried out about the equipment that make up the system, such as photovoltaic panels, inverter and bidirectional meter. In order to broaden the understanding of the procedures necessary for the operation of an on-grid system, a case study of the CPFL concessionaire was carried out, applying all the procedures described here, demonstrating a significant reduction in the amount paid for the energy bill of the consumer unit studied. Finally, a comparative study of an informative nature was generated between the CPFL, Light, CEMIG and Celesc distributors, on the documentation required at each stage of the process of connecting the system to the network, demonstrating that the operation of distributed micro and mini-generation is extremely important. importance for advancing the diversification of the national electricity matrix.

Capacitive deionization (CDI) has emerged as a promising electrochemical technology for the desalination of brackish water, which promotes the electrosorption of ions in the electrical double layer. In recent years, there has been significant growth in studies on capacitive deionization, however, challenging issues still persist, such as obtaining low-cost carbon electrodes with high electrosorption capacity and stability over electrosorption/desorption cycles, as well as a better understanding of how the hydrodynamic aspects influence mass transfer and process efficiency. In this sense, the objective of this thesis was to develop an activated carbon electrode using a polymer obtained from residual glycerol from biodiesel as a precursor and to investigate the effects of the architecture of different CDI cells on electrochemical desalination. The results showed that it was possible to prepare electrodes using residual glycerol polymer as the precursor. In electrosorption experiments, the PGAC electrode demonstrated stability over 50 cycles, applying voltages of 1.1 V and 1.2 V, in a symmetrical configuration, desirable behavior to allow the process for long periods of operation. However, when applying 1.4 V, the positive electrode potential exceeded the limit potential of anodic stability, causing oxidation reactions at the anode and, consequently, loss of desalination capacity. The asymmetric and membrane configurations (MCDI) were also analyzed in order to improve the salt adsorption capacity (SAC). Using an asymmetric configuration, it was possible to minimize the deleterious effect of co-ion repulsion, since there was an increase in charge efficiency (QE) from 62.9% to 88.4%. In the MCDI configuration, the application of ion exchange membranes led to a significant increase in the values of SAC and QE. This improvement is attributed to the presence of co-ions repelled from the micropores and which are prevented from migrating into the solution due to the presence of the membrane. These co-ions then accumulate in the macropores of the material, constituting an additional force of attraction of the counter-ions, since electroneutrality must be maintained. These results showed that the PGAC electrode, in addition to being a low-cost material, proved to be promising for brackish water desalination by capacitive deionization. In sequence, the comparison of the different CDI cells showed that the cell architectures influenced the mass transfer and kinetics of the process. For a thinner electrode, the flow-by cell (FBC) showed better desalination performance compared to the flow-through cell (FTC), due to the lower resistance to charging of the electrical double layer and higher diffusion in the micropores. However, for a thicker electrode a notable reduction of SAC occurred in the FBC, a result attributed to the lower mass transfer from the electrode surface to the adsorption active sites. This effect did not occur when using FTC, because in this architecture the convective transport of mass in the interstitial pores promotes a faster kinetics when compared to FBC. Considering these results, a percolation flow cell (PFC) was proposed, to combine the beneficial aspects of previously investigated cell architectures. With the flow of electrolyte percolating through the electrode and being perpendicular to the electric field, the PFC allowed the increase of optimized salt removal (OSR), due to faster mass transfer promoted by the permeation of the electrolyte through the carbon film of the electrode. An investigation of the particle size used in the preparation of the electrode showed that this size directly influences the mass transfer phenomenon, being possible to increase the kinetics constants with smaller particles, but they promoted a lower SAC due to changes in textural properties. These results showed that there is an ideal particle size to obtain a high OSR value. Finally, galvanostatic and quasi-single-pass mode analysis were analyzed using PFC. The results showed that higher flux flow and current density accelerate the kinetics, but quickly reach the cutting potential, affecting the OSR. Therefore, the operating conditions that showed to be more effective to obtain the highest OSR value were 7 ml min-1 and 1 mA cm-2, highlighting the importance of simultaneously analyzing SAC value and cycle time.

We sought to analyze the processes of tension evidenced in three experienced teachers, Early Childhood Education (ECE) mentors of beginning teachers (BT), participants. Tension can be characterized as opposition of ideas, feelings and actions and decision-making and actions of confrontations to these circumstances. These processes occurred from situations that provoked doubts, dilemmas, disagreements, conflicts, and difficulties throughout their participation in the Hybrid Mentoring Program (HMP). The HMP (2017-2020) - the investigative context of this study - refers to a constructive-collaborative research-intervention, funded by FAPESP, coordinated by UFSCar researchers. This program helped Basic Education BT (ECE, Elementary Education, Youth and Adult Education) with up to five years of experience, through mentoring actions, to deal with the typical difficulties of this career stage. The support offered to the PIs happened through hybrid formative actions developed by experienced teachers, autonomous and prepared to be mentors. Then, they participated in an initial and continued training throughout their performance in PHM. The theoretical basis of this thesis dialogues with notions related to learning and professional development, third space, professional conversations, mentoring (Mizukami, Reali, Zeichner, Loughran, Vaillant, Marcelo, among others) and with the Bioecological Theory of Human Development (BTHD), discussed by Bronfenbrenner (1996) and Tudge (2008). Data was provided by written narratives of the three ECE mentors recorded in diaries, activities in the Virtual Learning Environment (VLE), conversations on WhatsApp, online questionnaire and research reports, as well as individual interviews conducted during their activities in the HMP. From the identification of the dilemmas, conflicts, doubts, difficulties, etc. faced by each of the participants, episodes were selected regarding i) tensions experienced during the initial training process of the mentors in the HMP; ii) individual tensions arising from the lack of mastery over certain knowledge, divergence of pedagogical conception between mentor-BT and acting in the pandemic of COVID-19; iii) similar tensions faced by the three mentors associated with the difficulty of identifying the demands of the BT and in planning mentoring practices related to the NATIONAL COMMON CURRICULUM BASE and in the context of the pandemic of COVID-19. The results indicate that the tensions experienced by the ECE mentors arose as a result of the peculiar characteristics of the HMP, the very nature of the act of teaching to teach, issues arising from mentoring practices, and even aspects more external to the program. In all these cases, we observed the mobilization of the mentors - who put themselves in the position of learners - so that, while they sought alternatives to help their BT, they were also involved in a process of recognizing and overcoming their difficulties. Despite the discomfort caused by the tensions, the mentors were resilient in facing these situations and building new learning about being a mentor. The formative activities offered in the HMP as well as the collaborative exchanges with the mentor, educators and researchers favored the mentors' professional development.

This dissertation analyzes the scientific elites involved in the production of knowledge regarding meteorological and climate information in Brazil. To this do so, it was necessary a prior study of some currents of thought around the theme of the elites, a theme that is among the main issues discussed in the science since the end of the 19th century, and throughout the 20th century. Among the main currents of thoughts, stands out Pierre Bourdieu, since his work, together logic of the prosopographic methodology, provided the necessary means for a analysis of the Center for Weather Forecasting and Climate Studies (CPTEC), which is linked to national institute of space research (INPE). To this do so, it was necessary to present the origin, formation and trajectory of some of its main exponents, in order to bring this discussion to the academic debate with the aim of responding to how was the emergence of scientific careers in this group; as well as what the impacts of consolidation of an "elite" in the field of Brazilian climate science. We will investigate the characteristics of the CPTEC team in the period 2001-2010 with the objective of understand what are the essential leaders in the process of training and consolidation of the group of symbolically dominant researchers responsible for the production of data and information essential for monitoring, advancing and controlling studies Brazilian climate change

This is a qualitative approach study, developed in the intervention research modality, which had the purpose of understanding the obstetric violence impacts in the maternal health scope, identifying possible connections between the obstetric violence and the psychic suffering of women victims of this violence. For that, an online questionnaire publicized using the snowball sampling and the results of a focal group with 7 respondent women were used as data production techniques. Results: the analyzed narratives will be presented in 3 categories: the obstetric violence description from the participants' perceptions about that violence; the obstetric violence impacts in the women’s mental health; the obstetric violence resonances or effects in the women’s daily life. The study concludes that it is possible to identify violence obstetric impacts in the women’s mental health, from both the psych suffering and the trauma, symptoms and mental disorders development; as well as that the violence experiences can negatively affect the after birth activities, the motherhood and, even, a future motherhood perspective.

This research aimed to analyze how the characters with disabilities in comic books from Marvel publishers comics and Detective Comics (DC), considering comic books as means of mass communication through which many people come into contact with different cultural realities. Four characters were selected from each publisher, being heroes with disabilities who obeyed the following criteria: Relevance and possible implications that would have on the representation of disability, type of disability, and the amount of information available about he. A table was created containing the main information for each of the characters such as codename, publisher, how they acquired their disability, occupation, powers and abilities. The results point to situations that, sometimes, cover up the disability, passing the story through the myth of compensation and reducing the disability in order to overcome it with skills that compensate some lack, erasing the various social, physical and attitudinal barriers existing bodies for people with disabilities, as if bodies with disabilities do not could fully establish themselves in the heroic subject without making the need for major correction such as gaining super-powerful prostheses or superhuman abilities that compensate for the deficiency.

Purging blocks are important components located in the bottom of Steel Ladles. Its main objective is to protect and connect the ladle and the plug, throughout inert gas, usually argon, is injected into the liquid metal bath. Such components generally suffer with constant chemical and physical solicitation, which requires properties as high resistance to corrosion and thermal shock to be able to operate as required. Due to these solicitations, it is important that, during the production of the purging blocks, defects are minimized, such as micro cracks, which reduce their useful life and even make their use unfeasible. During the manufacture of purging blocks at the Monolithic and Pre-Molded Factory (FMPM) of RHI Magnesita located in Contagem-MG, several specimens began to present cracks after the drying stage, being discarded for not attend the required quality standard. This study aims to understand the cause and effect of the appearance of these cracks, as well as changing the calcium aluminate-based binder and the additives used in the concret production for the purging blocks, to propose a solution to this problem, avoiding the waste of raw materials and optimizing the production process of these strategic components for the steel industry.

Despite laws that guarantee the presence of deaf students in the classroom through resources such as sign language and the presence of an interpreter, there are many difficulties, especially in relation to subjects with very abstract contents and with technical terms such as the case of Programming Logic. The development of specific material for this discipline can be very useful, but in times of pandemic and social distance, how would construction be possible considering the teacher and interpreter partnership? The approach adopted for the development of this study is exploratory, using qualitative and quantitative methods. In a constructivist and interdisciplinary character, this work aimed to understand the dynamics of distance construction of material for deaf high school students in Programming Logic using available and low-cost materials and technologies. The Actor-Network Theory approach is used, which is based on the idea that human and non-human actors interact linked to a social network of elements, providing an analysis that helps to understand the dynamics of those involved in the construction of the teaching material. In this way, it was possible to observe how these humans or non-humans influenced each other and allowed better choices in the development of teaching materials. In a pilot test, a course on Programming Logic was carried out for deaf students, showing that the teaching material in video classes alone is not enough for the understanding of the deaf student, requiring the mediation of the teacher and interpreter and that this partnership is fundamental for the lesson planning and execution. There is also a preference of students for practice over theory. A questionnaire submitted to expert evaluators in the education of the deaf was applied to verify possible problems in the didactic material, opinions and suggestions were obtained that made possible the improvement in a second version. In the second round of evaluation, a good improvement was achieved in the aspects of visual communication. The results suggest that most of the problems reported about didactics in the first evaluation of the material were in the way of bringing the contents of the Portuguese language to Libras and that the creation of the material can benefit when supported by imagery elements to the detriment of texts only verbal offered by the teacher. The fact that the teacher and the interpreter were not recording the scenes together was one of the difficulties observed in obtaining a more interactive result. Images should be more valued and inserted at the time of construction of the text together with the interpreter so that contents and languages are valued. The communication and interaction between teacher and interpreter needs to be more intensified in order to improve the quality of information for the deaf student. The Actor-Network Theory made it possible to present the importance of non-human actors in the creation of didactic material, such as the storyboard, as well as helping to perceive the connections that must be strengthened, such as that of the teacher and the interpreter.

Over the past century Haiti has experienced successive international interventions in the name of peace. By alleging that Haiti’s internal instability threatens international security, the United Nations (UN) has undertaken peace operations in the country and installed administrative apparatuses to guarantee the proper functioning of democratic institutions, assessed by institutionally established criteria. This ethnographic analysis of one of the peace operations in Haiti – MINUSTAH – explores how the data production on the levels of violence builds an intervention-legitimizing consensus that mobilizes an international bureaucratic apparatus, whose role is to produce even more data in order to create what I call a “statecrafted landscape”. I carried out the field research among the documents, among the bureaucrats, among the Haitian social movements, and among the Brazilian military that participated in the mission. Empirical evidence from fieldwork among UN experts and Haitian activists suggest a mismatch between the Haiti inscribed in UN documents and the Haiti reiterated in local stories about the nation. By contrasting the production of ‘official history’ as a truth and ‘unofficial’ Haitian narratives, I will shed light on the relations of power involved in the enactment of historical facts. Field work among the military highlighted the relevance of the Brazilian Army's participation in MINUSTAH. Through combat experience acquired in Haiti, as well as the bureaucratic training required by the mission, the Armed Forces have improved their techniques for managing the territory and people, and have then reiterated their position as guardians of stability - at home and abroad - by manipulating legal resources to gain control over the population, engendering effects on internal politics and escalating a conservative and authoritarian power in Brazil.

Metallurgy was one of the first industrial processes developed by humanity, being improved according to the evolution of this species. Before, practically artisanal, today extremely industrialized and technologically updated. Inherently, its nature is a polluting industry, and can reach abiotic environments such as soil, air and water, thus impacting the balance of different food chains. The controls of its environmental impacts are mandatory and the results observed by a demanding market. Investments go beyond technological modernization, as it is verified that attention to human beings is essential in the development of an organizational culture that is conscious and committed to good environmental performance, thus naturally guaranteeing better results in performance indicators, and when associated with planning strategy, better competitive conditions in the market. Methodology: This study aims to understand from a Systematic Literature Review (SLR): i) how are the debates about the influence of organizational culture on environmental issues; ii) understand how organizational culture influences an Environmental Management System (EMS); and iii) whether the involvement of senior management is relevant in aspects related to organizational culture. The research shows an urgent need to produce knowledge in this area. Therefore, in view of this conclusion, pointing to the aridity of technical-scientific productions, which could more effectively guide this sector, the effective contribution of this dissertation is to indicate an area to be better explored and studied.

Introduction: Chronic noncommunicable diseases often affect older adults, who may experience decompensation and hospitalizations. Given the high prevalence of these diseases and increased longevity, many older people may have functional limitations and need a caregiver. However, family caregivers are not always able to develop the task of caring, which may lead to burden and family dysfunction, variables that can influence the quality of care provided. Therefore, early identification of these aspects is essential for planning interventions to improve the quality of life of these individuals. Aim: to analyze the relationship between family functionality and burden of informal caregivers of hospitalized older people. Methods: this is a cross-sectional study conducted with 98 informal caregivers of hospitalized older people in an inpatient unit of a large hospital in São Carlos, São Paulo. For data collection were used questionnaires to sociodemographic and care context characterization, to evaluate burden and family functionality. Descriptive analyzes and Spearman’s correlation coefficient were used. Results: female caregivers predominated, who took care of their parents and had no training. Approximately 59.8% of caregivers had good family functionality and 49.5% scored for mild to moderate burden. There was a negative correlation, moderate magnitude, between family functionality and burden (p<0,001). The higher the burden score, the lower the family functionality score and vice versa. Conclusion: caregivers with high burden had worse family functionality. Therefore, nurses need to identify such conditions early and implement assertive interventions so that the family functions as a therapeutic resource.

Sb2Se3 semiconductors have been shown to be excellent photocathodes with attractive optoelectronic properties when compared to other photoabsorbers commonly used. However, its photocorrosion in aqueous media prevents it from reaching satisfactory rates of photoelectrochemical (PEC) conversion and requires further modifications to make its use viable. In the present work, two co-catalysts are investigated separately to verify their influence during PEC experiments, these being MoSx and Pt. MoSx was deposited with different deposition cycles and showed a photocurrent density (jph) between −0.6 and −5.7 mA cm−2 at −0.2 VRHE, that is, a maximum value of ~70× greater than the non-modified film. The result showed that the lower the number of cycles, the greater its photoresponse, since the effect of parasitic light absorption was present. In addition, there was a reduction in the number of charge carrier recombination in the surface states in the presence of MoSx. Pt deposition was performed by electrodeposition (ED) and photoelectrodeposition (FED). The FED method resulted in superior performance compared to that in the absence of light, reaching a value 3× higher than the ED method, i.e., a jph value of −1.4 mA cm−2 at 0 VRHE. This result was related to the greater number of Pt particles distributed on the semiconductor surface due to the increase in available sites for Pt deposition. In short, the presence of both co-catalysts was essential for Sb2Se3-based semiconductors to achieve considerable results and allow their use as a promising alternative in solar water splitting. While MoSx needed to be in a strongly acidic medium and at −0.2 VRHE, Pt proved to be a more energetically favorable and eco-friendly alternative (i.e., at 0 VRHE and at pH 6.5).

Education is an institutionalized social practice, which the State has the duty to guarantee and promote its management. In this way, it is necessary to understand that it is part of a system – capitalism – and therefore undergoes changes according to the need to maintain this system, the economic and ideological interests of the ruling class. The changes that are promoted in the educational system occur through social policies, which have the function of organizing rights and duties of the subjects inserted there. Inclusion is part of these social promotion policies, aiming to alleviate inequalities, whether those arising from some type of disability, or due to the need for historical retraction, in order to make them actively part of society. However, the ways in which it occurs perversely include people with special educational needs, as it guarantees access and basic conditions in line with the law, but not effective permanence. That way, our objective is to analyze what was produced from public policies in the period from 1990 to 2020, in the Brazilian educational system at the federal level, in order to understand whether these regulations guarantee what is proposed in a more humanizing and inclusive education, as well as their intentions when actually applied. This work is intended to result not only in an analysis of these laws from a Marxist perspective, but also with the intention of producing a survey of legal formulations at the federal level for further consultation.

The design of new steels with high yield, ultimate strength and good ductility is one of the desirable goals of the industry. The ultra-high strength steels with twin induced plasticity (TWIP) effect are used in applications that demand high ultimate strength, tenacity and use at cryogenic temperatures. Nevertheless, the knowledge of the mechanical behavior of this class of materials under different load conditions is still an object of research. Austenitic stainless steels attend to this classification. In this work the mechanical behavior of a 316LV austenitic stainless steel was evaluated in tension and compression at different temperatures (-100 a 300 ºC) and strain rate of 10-3. The results of the mechanical tests were correlated to the microstructural transformations through evaluation by optical microscopy, x-ray diffraction and electron backscattered diffraction (EBSD) maps. The influence of temperature and strain rate on the mechanical twinning mechanism was analyzed. Based on the results, it was possible to propose a constitutive model proposed to predict the mechanical behavior

Objective: To characterize the knowledge of nursing students before and after expository and dialogued training and the participation, evaluating the implications of clinical simulation on self -confidence and satisfaction of participants after simulated experiences. Method: Methodological study, developed in two steps with use simulated clinical scenarios built through the Fabric Referential and Recommended Practices of the International Nursing Association for Clinical Simulation and Learning. The selection of the judges followed the criteria of Fehring and Snowball Technique, the collection of data occurred in two steps as Delphi. The analysis of the results considered the level of agreement 0.80. Results: Two scenarios were validated resulting in scale-level content Validity Index Global greater than 0.80; Both make up items on the prior knowledge of the apprentice, general objective and specific learning, theoretical foundation, responsible, complexity, documentation, briefing, theme, human and material resources, target audience, Team training, debriefing and evaluation. The analysis of the results in the second stage occurred in two moments, the first with the statistical analysis of the results from the scales and a descriptive analysis of student responses during telessimulation. In the first moment, a descriptive analysis was performed considering the PIEPER Knowledge Test before and after educational intervention. To identify if the average pre and post-intervention points were statistically different, it was considered the signaled classification test of Wilcoxon (1945). After the analysis of the knowledge presented by the participants before and after the intervention, specific evaluations were made about the intervention it self applied, using scales: simulation design scale (EDS) and satisfaction scale of students and self -confidence with learning (ESEAA). Conclusions: Scenarios simulated were validated for the teaching and learning of nursing students, to Evaluate and treat pressure injury in the hospital and home context. The educational strategy of telessimulation used in this study allowed the comparative evaluation of the perceptions of students in prevention, evaluation and treatment in pressure injury, characterizing the level of knowledge in pre and post educational intervention.

The use of rapid diagnostic testing (RDT) in primary health care (PHC) is one of the strategies of the Brazil's Ministry of Health to make it easier for people to access to timely diagnosis of some diseases of interest to individual and collective health, such as infections by human immunodeficiency virus (HIV), hepatitis B and C virus, bacillus that causes syphilis, SARS- Cov- 2 and others. RDT are immunochromatographic assays that allow quickly detection of the presence of antigen or antibody in the specimen tested. Its have the advantage of being easy to store and transport for collect in the field, without need of sophisticated techniques or reagents of difficult preservation. Thus, is not necessary complex laboratory structure for its execution, reading and interpretation. Its realization delay up to 30 minutes, considering all steps, what collaborates to reduce the overhead of central laboratories. It is hypothesized that PHC faces difficulties in incorporating this technology into the routine of services due to various contingencies. Objective: To describe the difficulties of PHC professionals in relation to the decentralization and implementation of RDT. Methodology: This is an integrative literature review carried out from March 2021 to July 2022. The data search was performed online on the SCIELO, PubMed, Google Scholar and virtual health library (VHL) data platforms. Because “quick test” is not a descriptor, we choset o search with words that, when associated, could refer to “rapid test”. (HIV; Human Viral Hepatitis; Syphilis serology; acquired immunodeficiency syndrome (AIDS) serology; serological tests, sexually transmitted diseases). This dissertation is the conclusion work of a professional master course, through which it was possible to elaborate a training proposal for the application of rapid tests in PHC. Results: 2,200 publications were found: 70 were duplicates and 579 were excluded; 21 were used in this integrative review. Conclusion: The process of decentralization of rapid testing in PHC is in progress and occurs unevenly in units across the country. Thus, among the difficulties encountered by health professionals, the lack of adequate environment and materials, deficiency in team training, insecurity of professionals in carrying out rapid tests in the delivery of results and work overload. Health professionals who work in PHC, in the process of decentralization and implementation of rapid tests, have similar opinions regarding this process, they know the importance of testing in the direct improvement of the population's health, they believe in a new model of health care, however, they report the difficulties mentioned above.
