Introduction: The changes imposed by congestive heart failure (CHF) on health status and poor prognosis can influence the behavior of autonomic cardiac modulation and worsen the quality of life (QL) of these individuals, especially in the presence of type 2 diabetes mellitus (DM2). Objectives: To evaluate whether cardiovascular variables and cardiac autonomic modulation are more affected in individuals with CHF and reduced left ventricular ejection fraction (LVEF) in the presence of DM2 when compared to isolated CHF. Methodology: Individuals diagnosed with CHF and DM2, distributed in 2 groups: GHF and GHFDM2. All were submitted to echocardiogram examination, assessment of the degree of physical activity, evaluation of QL and assessment of cardiac autonomic modulation. Statistical analysis: Student's t-test or Mann-Whitney test, Chi-square test and Fisher's exact test, with significance level of p <0.05. Results: i) GHF presented a mean RR interval response (iRR) to active postural change, however, the heart rate variability index didn’t change in response to this maneuver; ii) In the individuals studied, the DM2 associated with CHF doesn’t modify the QL. Conclusion: Individuals with isolated CHF respond to active postural maneuvers only with adjustments of the mean iRR, and that the presence of DM2 in CHF doesn’t modify the QL of these individuals.

The present work is an approach to the trajectory and documentary work of Miguel Mirra, Argentine filmmaker who has developed several works in the field of communication and audiovisual production, motivated by the action of social movements that have been formed in his country during the last three decades. In this context, it is proposed to investigate and analyze the methods, concepts and ways in which this director structures a type of social and political documentary film, whose objective is to make visible and be in solidarity with the oppressed, the excluded and the exploited peoples. Based on a referential framework with historical, political, economic, argumentative and stylistic components, the project provides a reflective analytical of the cinematographic, cultural and ideological proposals of Miguel Mirra, whose documentary film is an immediate reflection of the cinematographic movements that emerged in Argentina. From the second half of the twentieth century, they have aimed to project a distinctive point of view, in order to generate alternative visions and new spheres of the public.

In the family environment, individuals maintain their first interpersonal relationships with significant people, establishing important affective support for the development of each member. In this way, it is known that family is a privileged space for the development of the individual and of society. However, the birth of a disabled child can alter family relationships, and for many families there will be a need to undergo changes and adaptations. Considering the importance of families for child development and that parents of children with disabilities can experience parental experience in a differentiated way, this research aimed to identify and compare quality of life, resources, parental educational social skills, marital relationship, needs and social support, between parents and mothers of children with intellectual disability, physical disability, autism and delay in child development and correlate these variables. The research was developed with 120 participants, being 60 mothers and 60 parents. Participants were divided into four groups, each group being composed of 30 participants (15 fathers and 15 mothers). The groups were divided according to the diagnosis of children (intellectual disability, physical disability, autism and delayed child development). To collect data, the following instruments were used: Quality of Life Questionnaire "WHOQOL-bref"; Inventory of resources in the family environment; Script of Social Parenting Educational Skills Interview; Conjugal Relationship Questionnaire; Questionnaire on family needs and Social support questionnaire. These instruments contain quantitative data, which have been carried out measures of central tendency and dispersion. To compare the data of the parents and the mothers, from each group separately, the t-test was performed and the Pearson correlation test was used to relate the variables. The results showed that there were differences in at least one aspect related to quality of life, social educational parental skills, resources in the family environment, marital relationship, need and social support, when comparing fathers and mothers of children with intellectual disability, physical, autism and delayed neuropsychomotor development. As an exception, the items related to the follow-up and non-follow-up (G1, G2, G3 and G4), the daily activities of the child (G1, G3 and G4), the attitudes of the spouse who (G1 and G3) and social support (G4), which did not present statistically significant differences. The data suggest that the parents of children with disabilities experience their role in a different way, emphasizing that the interventions must meet the demands of the same considering their singularities. The correlations showed that the higher the parents' satisfaction with quality of life, marital relationship and social support, the smaller the family needs were, the higher the levels of social support were available, and the more skilled the parents could be. present in the parental and matrimonial relationship. It is concluded that the parental demands are modified depending on the deficiency and developmental delay that the child has. Thus, it is important to provide services, projects and programs that involve families and consider their real demands.

In this dissertation, we investigate the magnetoelastic properties of nickel ferrite compared to the pure metal nickel, either by ab-initio calculation or through experiments using the capactive cell technique. The first step of our approach is to establish the convergence criteria on density functional theory (DFT). This also required us to benchmark our method by using other materials such as pure Fe, Co and diamond. The first step of our study is to explore not only the approach of DFT but also its capacity to describe other properties. Since all the electronic structures of theses material have been suitably reported, the second step of our calculation demonstrates how close to the experimental data DFT may result the elastic constants. The results has shown reasonably error to the actual values. On the third moment, our investigation resides to find the magnetostriction coefficient through DFT, which met in accordance with the experiments we carried out using the capacitance technique.

The Distance Education has undergone significant changes that concerns the way in which the teaching work is organized. In the modality, not just one, but multiple professionals should work in consonance to guarantee the teaching-learning processes. In addition, in the Brazilian experience, the Distance Education has been developed, in public institutions, by policies with an emergency character such as the Universidade Aberta do Brasil System (UAB). In addition to the inherent complexities of the teaching work in Distance Education, it is added, therefore, related aspects in the precariousness of work. Thus, this research has the main objective of analyze the consequences from the teaching work organization in the Distance Education in light of the concept of polidocência. In order to meet the main objective, our analysis is based on five specific objectives: to perform a bibliometric study on the scientific production of the area; to characterize the Universidade Aberta do Brasil system and the configuration of the teaching adopted in its courses, analyzing the implications in the institutionalization of the Distance Education; to discriminate the division of teaching work and its implications for teaching in the Distance Education; to investigate the labor relations between teachers in the Distance Education; to explore the teacher knowledge used in Distance Education and its implications in the relations of power and knowledge in the context of polidocência. About the methodology, we used methodological triangulation, considering that we simultaneously used qualitative and quantitative methods. The methodological procedures, in turn, occurred as follows: bibliometric analysis using the thesis basis elaborated by the Grupo Horizonte; documentary analysis from the pedagogical projects of courses offered under the UAB System; application of virtual questionnaires to teachers-authors, teachers-applicators and virtual and face-to-face tutors who work or have already worked in the UAB System; semi structured interviews with these same teachers. Through this research, we observed that the researches about Distance Education and especially about teaching work in the modality, still represent a very small part of the scientific production related to Education in Brazil. We also verified that the UAB System has standardized the configuration of teaching work in the Distance Education. Our study also reveals that teaching in the modality is divided and fragmented, so that each professional is responsible for a specific set of activities and functions. In addition, the Distance Education has characteristics related to productive restructuring, such as flexibilization and teleworking, which, among other aspects, promote perversities for the teachers. In the research we also identified that the constitution of teaching knowledge is complex. Thus, the knowledge base for the teaching of each professional comes from multifaceted sources and includes knowledge of digital technologies. Our study also suggests that the relations of knowing relate to those of power in the context of polidocência.

The concern with the future of water on the planet has increased in past years, mainly due to the recent water crisis suffered throughout the country. The dissolved air flotation (DAF) operation is an example of the resumption of studies in the application and optimization of classic industry operations and has its potential for water treatment confirmed in the literature. It is characterized by using air microbubbles for the removal of suspended particles in liquid mixtures and has already been presented as an useful operation for treatment steps, however, with a high operating cost. In the study of flows in equipment, the Computational Fluid Dynamic (CFD) technique has been highlighted. This technique can aid in analyzing and obtaining information on constructive equipment configurations, scaling parameters and optimized operating conditions. In this work, the Ansys Fluent 14.5 software was used for the CFD simulation of the DAF process in horizontal tank, seeking to fit a representative mathematical model (set of equations) and numerical procedure based on experimental data from the literature. Initially, for the definition of the computational mesh, the GCI test was applied, capable of quantifying the mesh discretization error. Then, different multiphase models that consider the Euler-Euler approach were compared through the qualitative behavior for the diameters of 30-50-70 μm. With the diameter of 50 μm, the influence of the turbulence, trawling and contour conditions for the tank surface used by the literature to represent the FAD process was verified. After adjusting the fluid dynamics model, the population balance equations (EBP) for the microbubble size distribution was applied and the influence of models describing the phenomena interaction like coalescence (turbulent and Luo model) and breakage (Luo model) in the structure of the air flow and air distribution was verified. A greater influence of the coalescence phenomenon was observed.

The objective of this research was to analyse which initiatives and repercussions with regard to the democratization of the affirmative policies of action about the admission and continuity in the college education of the degree course of the Pedagogy of UERJ, in accordance with the 12.711/12 law though the prevailing professors outlook of the recurrence painted out and forwarding demanded for the attendance to the students from the reading of your institutional reality. The central points of the leading me course are: a) affirmative action policies in international experiences; b) the contextualization of affirmative action policies within the framework of Brazil's public educational policies; c) explaining the genesis, development and deployment of education policies actions in the UERJ and d) discuss in the light of the prevailing speeches the perspective of the professors of the Pedagogy of UERJ a reading between proposition, actions and demands. The theoretical methodological axis was preliminarily a bibliographical and documentary survey through the Bank of theses and dissertations of CAPES and the institutional repository of documentary base of UERJ. The Collective Subject Discourse (DSC in Portuguese) was used as an analytical theoretical framework, which emphasis was to situate and filter incidences of discourses, recurrences and demands, guided by the quanti-qualitative approach and in this section, the case study, considering that the UERJ is the local epistemological research. As one of the instruments of data collection, interviews were chosen through a semi-structured script, preceded by characterization of the respondents. We had 17 returns as the respondents set, that is, professors who work with disciplines in the Pedagogy course. In the procedural scope, we use the documentary analysis technique (CELLARD, 2010) regarding UERJ records and initiatives and more specifically the pedagogy course in the referral of the recurrences to attendance, debate and reflection on the affirmative action policies within it. Regarding the data collection technique, the interviews helped us to understand the respondents' perception of the meanings and meanings that were triggered within the pedagogy course in the reality of UERJ (POUPART, 2010), followed by content analysis (BARDIN, 2009) and Collective Subject Discourse (LEFEVRE, 2014). Through the return of the respondents, it was verified that the affirmative action policies implemented in 2002/2003 the UERJ selection process through the statutes 3524/00 and 3708/01 and continue to fulfill their objectives of providing population access to university education, but in the Pedagogy course, due to low competition, the access to the course is seen in a simple way. Professors, for the most part, know the quota system and support it. They report that there was no impact of the quotas reflected in the classroom, because they reach their goals in the classroom and they do not notice a difference between the student and non-quotators, because the difficulties presented in the first moments are general, having the coordination of the course as support to the students as voluntary initiatives of teachers. However the inclusion to the university education is a subject that do not requires only suitability programs of the inclusive ones, are effective necessary polices to the non exclusion of the expropriated in a social and economic way.

Introduction: school is a favorable environment for health problems. Prevention and health promotion actions are priorities, however, it is necessary for teachers to know how to handle the situation. Yet educators are fearful and insecure. General objective: to analyze the self-confidence of preschool and basic education teachers with regard to the management of health problems at the school. Specific objectives: to describe the construction and validation of the visual analog scale of self-confidence of teachers to handle health problems at school and to identify the factors associated with self-confidence before and after educational activities and associated to the promotion of self-confidence. Method: organized in two stages: the first stage refers to the first specific objective and is characterized as a methodological study. Twelve judges participated in the content validation and 25 teachers in the semantic validation. Internal consistency was determined by Cronbach's alpha coefficient. The second stage addressed the second specific objective and is characterized as a quasi-experimental pre- and post-test study. Seventy-six teachers participated, subdivided into four schools. For each school, the production of the empirical material took place in three meetings. The research instruments used were: characterization tool; Visual analog scale of teachers' self-confidence to manage health problems at school; Knowledge assessment questionnaire to deal with health problems at school and Scale of satisfaction with the simulated clinical experiences. The educational activity consisted of four simulated scenarios. Data were analyzed using descriptive and analytical statistics, using the Mann-Whitney test, Kruskal-Wallis, Spearman's correlation coefficient and multivariate linear regression. The ethical provisions for research involving human beings were met. Results: The final visual analog scale consists of 12 items. All items were evaluated as pertinent, obtaining 100% of agreement among the judges and being considered clear by the target audience, with high internal consistency among the items. Regarding the second stage, a low average self-confidence score was found before the educational activity. After participating in the simulated scenarios, self-confidence was promoted. The variable "background experience with health problems" presented a statistically significant association with the mean self-confidence score (p=0.026) and the mean self-confidence promotion score (p=0.001). The variable "knowledge promotion" had a weak negative correlation with the mean self-confidence score (p=-0.273). The variable "professional experience" maintained a significant relationship with the mean self-confidence score in the post-phase (p=0.008). Final considerations: teachers feel uncomfortable to cope with health problems at school. The results can support the planning of health education actions in the school environment.

Our main goal is to study Hopf algebras and Galois objects, from the point of view of the polynomial identities, more precisely how these objects are distinguished by their polynomial H-identities. To this end we follow the program started by C. Kassel. There he defines polynomial H-identities to H-comodule algebras, gives some properties of these T-ideals and uses Galois objects classifications, as made by Bichon for the monomial Hopf algebras of type I, to find polynomial identities that distinguish those objects. In that case, the existence of an algebra homomorphism such that the kernel coincides with the T-ideal of the H-identities is crucial.

Due to the increasing demand for potassium in Brazil, it is feasible to exploit carnallite in order to supply part of the national need for this alkali metal, whose reserves of raw material - in this case sylvite - are depleted and, therefore, at imminent risk of scarcity. This work proposes to develop, simulate and verify the economic feasibility of the process of dissolution and crystallization of potassium chloride (KC1) from the Carnallite ore, based on theoretical and practical data available in the literature. By means of applied methods and observation of the results, it was verified that the reconstruction of the system diagram KCl-NaCl-MgCl2-H2O (Hoffman, 2004) and the obtaining of its representative equation presented positive results, verified during the comparison between values calculated in the equation and values collected from the original diagram. Another crucial factor in obtaining the equation is that it makes it possible to calculate the concentrations of potassium chloride (KCl) and magnesium chloride (MgCl2) at various temperatures, from 0ºC to 105ºC, which is more imprecise from the interpolation of the limited diagram temperatures. The proposed process provided more than 85% crystallization of potassium chloride, demonstrating its superior performance compared to existing procedures. In this work the simulation of 3 process trajectories was developed, with all its variables and results. These were effective for studies of the determination of the crystallization processes of potassium chloride (KCl) and its economic feasibility, since in Brazil the situation is of a market with great demand and possibility of expansion, an agricultural country and in full development of technologies to expand production, which may mean an increasing demand for potassium chloride (KCl) as fertilizer. The best simulated configuration (higher yield) provides a return rate of 93.71% of the capital invested in a year.

Introduction: Individuals after stroke expend more energy during walking and this contributes to an increasingly inactive lifestyle, increasing the risk of developing a new cerebrovascular and/or cardiac events. The Compendium of Physical Activities may overestimate or underestimate energy expenditure in people following stroke. Thus, more accessible methods to estimate energy costs in this population are important to prescribe physical activity and exercise. Objective: To evaluate whether there is a correlation between StepWatch™ Activity Monitor (SAM) and the energy cost of walking in participants after chronic stroke. Methods: This study is a correlational, cross-sectional pilot study. Twenty participants following stroke were analyzed. All procedures were carried out in two days. On the first day, the performance on the six-minute walk test (6MWT) was measured, and then the SAM was placed on the participant’s non-paretic ankle. Metabolic variables were collected using a portable metabolic system (Oxycon Mobile®) during walking in the 6MWT. Nine days later, the participants returned and the SAM was removed. The energy cost of walking was calculated by dividing peak oxygen consumption by the distance in meters achieved in the 6MWT. Spearman’s rank correlation coefficient was used to evaluate whether there is a correlation among variables of interest and the magnitude of the correlation was based on Munro’s classification. All analyses were carried out with the SPSS 20.0 software with a significance level of 5%. Results: The energy cost of walking correlated with the number of steps (r¬s = - 0.666, p = 0.001), percentages of time in inactivity (r¬s = 0.503, p = 0.024), low cadence (r¬s = 0.782, p < 0.001), medium cadence (r¬s = - 0.632, p = 0.003) and high cadence (r¬s = - 0.673, p = 0.001) and the percentages of steps taken at low cadence (r¬s = 0.707, p < 0.001) and high cadence (r¬s = - 0.620, p = 0.004). Conclusion: SAM seems to be a good activity monitor to infer the energy cost of walking in people following chronic stroke, and should be considered to help clinicians to prescribe exercise for the prevention and treatment of cardiovascular diseases after stroke.

In the last years several strategies have been developed by companies that intermediate the communication between the passenger and the taxi driver with the call applications. This intermediation is known as assigning a taxi to a passenger and is used in methods of dispatching taxis. To select a taxi it is necessary to adopt some strategy, such as: the taxi nearest to the passenger, the taxi that has the least estimated time arrival, among others. It is worth mentioning that at any moment passengers can cancel the request and taxi drivers can cancel the service. Several factors lead to this type of cancellation, being for the passenger the main reason for the distance of the driver and the driver the destination of the passenger, because the driver only has the knowledge of the destination of the passenger after the accept of the request. In this way, depending on the adopted strategy, we can assign a taxi that does not have the interest in accept this request or canceled. One of the strategies related to the dispatch of the taxi to the passenger is to direct the service requests for the taxis with the greater chance of acceptance. Thus some parameters can be analyzed for decision making regarding the choice of taxi to be assigned to the passenger. In this scenario, the optimization methods can be used to aid the decision-making process and, thus, to select the taxi with the greatest chance for service. Therefore, the objective of this work is to propose an optimization method that uses a mathematical model of linear programming for decision making of which taxi to be assigned to a determining passenger in order to direct the request to the taxi with greater chance of acceptance. In this taxi dispatch method, the following criteria will be adopted: distance between taxi / passenger, taxi's note given by the passenger, taxi driver's cancellation and refusal quantities, taxi's fidelity stamp, go to home and the aging index for the homogenization of taxis / passenger assignments. Actual data were used in the tests and comparisons considering the point of origin of the taxi and the passenger were performed. In the comparisons, the Euclidean distance methods and the actual distance calculation method were used (the latter, carried out through the collaborative mapping project - OpenStreetMap. The analyzes related to the diversity of parameters for taxicab / passenger assignment were performed and demonstrated the influence of the weights assigned to the parameters in the mathematical model and showed that the sending of the requests were to the taxi drivers with greater chance of acceptance.

The generalized gamma (GG) distribution is an important model that has proven to be very flexible in practice for modeling data from several areas. This model has important sub-models, such as the Weibull, gamma, lognormal, Nakagami-m distributions, among others. In this work, our main objective is to develop different estimation procedures for the unknown parameters of the generalized gamma distribution and related models (Nakagami-m and gamma), considering both classical and Bayesian approaches. Under the Bayesian approach, we provide in a simple way necessary and sufficient conditions to check whether or not objective priors lead proper posterior distributions for the Nakagami, gamma, and GG distributions. As a result, one can easily check if the obtained posterior is proper or improper directly looking at the behavior of the improper prior. These theorems are applied to different objective priors such as Jeffreys's rule, Jeffreys prior, maximal data information prior and reference priors. Simulation studies were conducted to investigate the performance of the Bayes estimators. Moreover, maximum a posteriori (MAP) estimators for the Nakagami and gamma distribution that have simple closed-form expressions are proposed Numerical results demonstrate that the MAP estimators outperform the existing estimation procedures and produce almost unbiased estimates for the fading parameter even for a small sample size. Finally, a new lifetime distribution that is expressed as a two-component mixture of the GG distribution is presented.

Zeolites are microporous, crystalline aluminosilicates that have numerous advantages due to their intrinsic properties such as acidity, hydrothermal stability and shape selectivity. However, the presence of micropores causes diffusion limitations and reduces the accessibility of the molecules to the active sites. To overcome this problem, mesopores are generated in zeolitic framework, combining characteristics of microporous and mesoporous materials. In the present work, the USY zeolite was modified by alkaline treatment in the presence of the CTABr surfactant and subsequently hydrothermal treatment. The influence of the alkaline medium, surfactant concentration, hydrothermal treatment time and temperature on the framework, textural and chemical characteristics of zeolites modified was evaluated. By X-ray diffraction and nitrogen adsorption, it was found that mesopores are generated in the USY zeolite while maintaining its faujasite framework. It has also been observed that the simultaneous presence of the basic medium and the surfactant is required for the formation of mesopores. By dispersive energy spectroscopy (EDS) analysis, it was found that the overall Si/Al ratio of the USY zeolite was kept constant after the modification. The samples were evaluated in the esterification reaction between acetic acid and butanol or tert-butanol, concluding that the amount of acid sites was more relevant than the mesoporosity generated.

The goal of this research was to study and to understand the educational processes from the social practice of Rock through the trajectories of the lives of some musicians from São Carlos. The theoretical purposes start from a perspective that Rock is a social practice and that through this practice the educational processes occur. Therefore, authors such as Oliveira et al., Brandão, Chacon, França, among others, constituted the basis for comprehending Rock as a social practice, both from the educational perspective and from music itself. Other authors such as Freire, Fiori and, again, Brandão supported the educational concepts, and Joly, Severino, Souza, Green, Lacorte, Galvão and others constituted the basis of the concepts regarding the musical education. The methodological proceeding used for the data collection was the “História Oral” method, in which the collaborators, in this case, Rock musicians, shared their musical and life stories in friendly meetings with the researcher. The hearing, the appreciation of the other the act of living with others and the solidarity were important aspects in this relation between researcher and collaborator. The authors used as reference to the “História Oral” method were Thompson, Meihy, Holanda and Alberti. The organizing of the data had as a reference point the Content Analysis, especially the one that was described by Franco. What came to be revealed as educational processes were those that were related to the musical learning, what made possible for the musicians to live their lives more fully and to contemplate the human relations and the life aspects in general. Some aspects like the importance of the family as a mediator of the musical and the human educational processes as well as the school and the learning within a group of friends emerge in the lives of these musicians in an effective manner as a result of the social practice in the Rock environment.

Motivation is considered an important variable in the process of learning a foreign language. The nature of students' motivation is complex and variable, and can be influenced by internal factors, specific to the learner, and external factors related to their school context. In this scenario, we consider that actions of the teachers can favor the motivation of the students during the class. We established as objectives of this research: to investigate how motivational strategies can be applied in the Spanish classes and to analyze how the teacher can contribute to promote and/or maintain the motivation of the students. This work is based on the concepts of motivation in foreign language learning (PINTRICH and SCHUNK, 1996; GARDNER, 2001 and DÖRNYEI and OTTÓ, 1998). It is also based on the concept of motivational strategies in language classes (DÖRNYEI, 2001). This is a qualitative research and was carried out based on the action-research methodology. The data were generated in a Center of Language Studies in the State of São Paulo and the participants were 08 students of Spanish as a foreign language and their teacher who is also the researcher. The following instruments were used to produce the data: questionnaire, student-participant and teacher-researcher diaries. The results show a number of factors that influence the students' motivation.

Monitoring tools have evolved over the years to keep support of advances in computer network technology, adapting to new paradigms such as virtualization, software orientation, and more recently a programmable data plan. However, few advances have been made in the area of interface and interaction in network management systems, nor to know about the main actor, the network administrator, who uses these tools to solve problems and make decisions. Thus, in the current dissertation we present a investigation based on the HCI perspective, through the analysis of data collected in both field researches and experimental approaches, which together enabled the development of recommendations for software developers to the (re)design of data in network monitoring tools.

The present work was developed according to the methodology of bibliographical, documentary and field research. It aims to investigate the projects and actions in the area of education accomplished by the social movements of culture of the region of Sorocaba / SP, in order to reveal if the praxis of these movements can collaborate with the fight for the construction of another hegemony. To do so, the text begins with a discussion of the multiplicity of the concept of culture and the dichotomy between postmodern and Marxist perspectives in the study of the term. This debate continues guided by the Gramscian Marxist approach, in order to present the culture from the historical-dialectical materialist paradigm. In the sequence, the concept of social movements is discussed, presenting studies on the history of social movements in Latin America, the conceptualization of social movements of culture, a discussion about the limits existing in the so-called theory of new social movements and ends with the exercise of to approach social movements in the light of historical-dialectical materialism, according to the Gramscian perspective. In the third and final chapter is the analysis of education projects carried out by the social movements of culture of Sorocaba / SP, where it is evident that the praxis of these movements, which in general are not oriented by a centrality in the class debate, , yet an important instrument in the struggle for overcoming the capitalist mode of production. In the conclusion, it is evident the need of interpretations of the term culture that transpose those that designate the concept only as a mere reflection of the material relations, just as it also demonstrates the still incipient character of the studies on the social movements in the light of historical materialism suggesting that advances in this field of study may reveal the impacts of social movements on concrete reality.

The aim of this research is to analyze the work activity of higher level teaching, identifying the constraints that the professionals of this category are submitted, due - especially - to the system of evaluation of the intellectual production linked to the postgraduate programs. It will be studied the teacher’s activities that works in the Department of Production Engineering (PE) of a federal public university, in the interior of the state of São Paulo. The choice of this theme considers that the teaching work started to have a new logic in the academic routines, based on the acceleration and intensification of activities and the stimulus to productivity, that reproduces in the university scope the characteristics of flexible work. Thus, the teaching activity, related to teaching, research and extension, as well as the administrative management of the university, will be analyzed from the perspective of the Activity Ergonomics. As for the methodological design, this research is classified as descriptive, with a qualitative approach, of a bibliographic character, complemented by the application of a single case study, outlined by the methodological approach of the Ergonomic Work Analysis (EWA), which allows to systematize the investigation of situation of the work environment. he results show that the teachers who work in the postgraduate program of the selected institution are submitted to greater constraints and experience feelings of frustration due to the charges for publication. Some teachers consider the evaluation of intellectual production as an oppressive and motivating process of unproductive productivism, which does not reflect the performance of a good teacher in the exercise of his teaching, research and extension activities. Despite the physical and cognitive impairments arising from the function, the work environment, the autonomy to perform the activities and the satisfaction in developing research are factors that positively influence the work activity of this labor category. Therefore, higher level teaching has proved to be an activity of high physical and cognitive demand and represents an even more pronounced dichotomy in graduate studies, between the pleasures of producing knowledge and the wear and tear that the demands of intellectual production impose.

Late-expiratory neurons (late-E) located in the parafacial respiratory group (pFRG), a critical region for the emergence of active expiratory pattern, are conditional and remain silent at baseline conditions. In situations of metabolic challenges, these neurons become active and contribute to increase the abdominal motor activity during the late expiratory phase. It was found that late-E neurons are silent at rest due to inhibitory inputs. Interestingly, in conditions of sustained hypoxia (SH), commonly observed in people moving to high altitudes, this inhibitory drive is reduced and generates the active expiratory pattern. In the present study we hypothesized that the Bötzinger complex (BötC), located in the ventral respiratory column, plays an important inhibitory role on the emergence of active expiration. We also explored the possibility that BötC inhibitory mechanism is reduced after SH and the activation of this mechanism is able to normalize the expiratory pattern of SH rats. The aim of the present study was to explore the contribution of the BötC neurons in the generation of the active expiratory pattern in control and SH (10% O2, 24 h) rats. To reach this goal, we recorded the pulmonary ventilation (in vivo) and respiratory motor activity in in situ preparations of juvenile rats (60-80 g) to evaluate, under normocapnic and hypercapnic (8-10% CO2) conditions: i) activity patterns of BötC post-I (n=5) and aug-E (n=9) neurons of control rats; ii) changes in the respiratory pattern after BötC pharmacological disinhibition of control rats with gabazine (GABAA receptor antagonist, 250 μM, n=7) or strychnine (glycine receptor antagonist, 10 μM, n=7); iii) the respiratory pattern of SH rats in situ (n=7) and in vivo (n=12); iv) effects on the respiratory motor activity of control (n=7) and SH rats (n=7) after microinjections of L-glutamate in BötC (10 mM); v) changes in respiratory pattern of SH rats (n=8) promoted by the pharmacological disinhibition of the BötC with strychnine (10 μM). In control rats, post-I and aug-E neurons were recorded under hypercapnia (8% CO2). Hypercapnia evoked late-E activity in the abdominal nerve (AbN), in association with a decreased post-I activity and augmented aug-E activity. Regarding to the bilateral microinjections of gabazine in the BötC of control rats, we observed a decrease in baseline phrenic nerve (PN) bursts frequency and increases in the expiratory time and in the AbN activity, with the emergence of late-E bursts. On the other hand, bilateral microinjections of strychnine in the BötC of control rats diminished the PN, vagus (cVN) and AbN nerve amplitudes, but did not modify the 3-phase respiratory pattern; and attenuated the emergence of the active expiratory pattern under hypercapnia conditions. Concerning the basal ventilatory pattern of unanesthetized SH rats, we observed an increase in minute ventilation, associated with a higher respiratory frequency and tidal volume. These findings obtained in in vivo parallel with our data from in situ preparations, showing that SH evoked active expiratory pattern at baseline conditions. BötC stimulation of SH rats with L-glutamate was able to briefly abolish AbN late-E activity. In addition, BötC disinhibition of SH animals with strychnine eliminated the late-E AbN firing and restored the respiratory motor pattern, similarly to control animals. Taken together, our results indicate that BötC perform a relevant inhibitory role on the mechanisms of active expiratory pattern generation. In addition, short-term SH seems to change the activity of BötC neurons, reducing this inhibitory drive and contributing to the emergence late-E AbN activity at resting conditions in these animals.
