This study was instigated by the documentary Van Gogh (1947), by Alain Resnais. The main reason for this analysis was given by the peculiar structure of the short film that had only the painting of Vincent Van Gogh as a source image. This nature allowed us to believe that the filmmaker's intention was to 'make' cinema from plastic pictorial material. And he did so in a dynamic that involved his process of creation and that of the painter, because at the same time that he thought the pictorial image, he conjectured it as cinema. Analyzing the creative movement of the artist the director supposedly evidencedhis own movement. The analysis of the structural transformation experienced by the painting was carried out according to the transcreation studies (Haroldo de Campos), of poetic translation (Roman Jakobson) and the implications of the poetic, phatic and metalinguistic functions in the elaboration of the aesthetic object. For this unique condition Van Gogh we recognize it as a film-essay (Arlindo Machado and Ismail Xavier) that transcends the paradigms of the documentary genre. We also sought to guide our analysis of translation from Jacques Aumont 's three operations: diegetization, narration and psychologization, which allowed us to point out the translation procedures (filming, editing and oralized text) responsible for the transformation of painting into cinema.

This study aims to analyze the behavior of Omentin and Vaspin in relation to a high intensity interval training protocol (HIIT) in rats fed a hyperlipidic diet. To this end, male Wistar rats, divided into 4 groups, received standard or high fat diet depending on the group for 4 weeks. After the induction to body fat gain, the training protocol began, with duration of 10 weeks, divided in 2 weeks of adaptation and 8 of HIIT. The animals in the trained groups performed 3 training sessions per week. Body mass and food intake were measured daily. At the end of the experimental period euthanasia occurred by decapitation, 48 hours after the last training session. Blood was collected and the tissues: gastrocnemius muscle, liver, epididimal white (EPI), retroperitoneal (RET) and visceral (VIS) adipose tissue were removed and immediately weighed. Serum concentrations of the cytokines TNF-α, IL-6, PCR, IL-L8, IL-10, IL-4 and adipokines omentin, vaspin and adiponectin were determined by ELISA and protein expression of omentin and vasin by Western blotting . The results are expressed in mean and standard deviation, the statistical comparisons were made through analysis of variance, and p <0.05 was considered to denote statistical significance. The results demonstrated that the hyperlipid diet protocol is able to promote a significant gain of body fat in 4 weeks, besides promoting, at the end of the experiment, an increase in serum levels of vasin and triglycerides. On the other hand, the high-intensity interval training was able to improve the animals' maximum exercise capacity and to slow the increment of the fat gain. However, training promoted an increase in total cholesterol levels and a reduction in serum adiponectin levels in IL- 10. Thus, the research supports the evidence that high-intensity interval training is able to mobilize fat significantly in a population with excess body fat, however, due to suppression of adiponectin and IL-10 levels, this may not be the ideal protocol for this population in such circumstances and we reinforce the use of vaspin as a biomarker for obesity.

This doctoral thesis resulted from a research process that was developed along a stretch of the Brazil-Bolivia border, in the southwest of Mato Grosso. In order to develop the study, the period 1940-2016 was delimited and an extension of the border area comprising the rural towns of Santa Clara do Monte Cristo, also known as Ponta de Aterro or Punta de La Carretera, part of the Nossa Senhora Aparecida and the community of Morrinhos, which belong to the municipality of Vila Bela da Santíssima Trindade. In the Bolivian side, the research covered the Vila de San Vicente de La Frontera and part of its surroundings. This study sought to analyze the meanings of that frontier in the perspective of the distinct frontier groups inhabitants of the region, composed of merchants, rural residents, farmers, public servants, remnants of the “Chiquitano” indigenous people and representatives of the Bolivian government. For that, investigations were made about the occupation and settlement process of the region, the social relations, constituted sociabilities and the forms of territorialization used by that society. The methodological procedures adopted were: direct observation with registration in field book; interviews and documentary research. The analysis was built using the inductive method, with a perspective and a qualitative approach, using narratives effectively, supported by oral history tools and intensive field work, with selection and direct contact with the investigated subjects. In sum, it was concluded with the study that "the self and other" in the boundary Brazil-Bolivia border are constituted from the differentiations of the subjects and not only on the nationality factor, since the limit can be constituted in a real or imaginary form, which transpires in the social relations established between frontier settlers, including: culture, language, parties and other forms of sociability. The frontier, in this sense, extrapolates the meaning of limit, of the material rigidity of the existence of a physical place. It transcends, heading for the between-places.

Beta thalassemias (BT) are a group of hereditary diseases characterized by the partial or total suppression of beta globin chains synthesis. Clinically, it manifests itself in three distinct forms: minor (BTm), intermedia (BTI) and major (BTM), and are differentiated by the frequency of transfusions, being the most severe form BTM. Since it is known in the literature that BT phenotype occurs independently of the genotype, a study conducted by the group, evaluated globally, genes that were differentially expressed in patients who had the same genotype, but different clinical presentation. By analyzing these results and looking for genes related to the increase of reactive oxygen species (ROS), responsible for causing cell damage and collaborating even more with the reduction of the erythrocyte lifespan observed in these patients, we identified the genes ABCB10, APEX1 and HMBG1 as differentially expressed, the former being increased in BTI patients and the latter two being increased in BTM. Peripheral blood samples extracted from a control group (n = 9), a BTI group (n = 8) and a BTM group (n = 4) were used to perform the real-time PCR experiments; for the experiments with CD34 + cells two healthy cultures and two containing the IVSI-6 mutation were used on the 7th, 10th and 13th days; A control group (n = 4), a BTI group (n = 5) and a BTM group (n = 6) were used to determine the protein content of APEX1, and a control group (n = 4) ) and a BTI group (n = 5) for the HMGB1 experiment. The data were analyzed using the GraphPad Prism 6 software and considered significant values of p <0.005. Using the real-time PCR technique (qPCR), we confirmed these results in a larger number of patients. The ABCB10 gene, on average, was 5 times more expressed in BTI patients (p = 0.0077). The APEX1 and HMGB1 genes were differentially expressed in patient BTM (both 3 times). Analyzing the expression of these genes during differentiation of thalassemic beta cells in CD34 + cell culture, compared to healthy cells, by real-time PCR, we found an increase in ABCB10 expression and a decrease in APEX1 and HMGB1 at the end of the differentiation. A protein analysis using western blot indicated that the protein content of APEX1 is increased in the two phenotypes of BT indicating its relation to the disease independent of the phenotype. Since erythroid cells did not show detectable amounts of HMGB1 in the cytoplasm, it was analyzed in the plasma of healthy individuals and BTI, showing a significant increase of this protein in patients. In this way, we conclude that our results contribute with unpublished data for the literature and can show in the case of differential expression of ABCB10, a more efficient response against oxidative stress, besides an important role in the erythroid differentiation in BTI patients. The higher production of APEX1 in beta-thalassemic patients seems to be independent of the phenotype being associated with the disease and related to the increase of oxidative stress observed in these patients. Finally, increased secretion of HMGB1 in the plasma of patients may be associated with prolonged inflammatory conditions, contributing to systemic cytotoxicity. The data presented here contribute to a better understanding of the disease, pointing out new targets for future studies.

Most ceramic tiles have a slip layer and this has a significant influence on the characteristics of the ceramic tiles. In contrast to this reality, the specialized literature on engobes is sparse and superficial. It is known, from experience, that the engobe layer influences the texture of the glazed ceramic tile surface, the curvature of the tiles, the appearance of pathologies such as the water stain, etc. In this context, the objective of the present work was to contribute to a better understanding of the role of the engobe in the ceramic tiles. For this, the influence of the fusibility variation and coefficient of thermal expansion of different engobes on the development of the central curvature of the tiles during and after burning was studied. Four engobes with different coefficients of thermal expansion and different fissures were developed. To determine the fusibility of the engobes, a heating optical microscope was used and a contact dilatometer was used to determine the coefficients of thermal expansion of the engobes and the substrate. In order to evaluate the influence of the differences in the coefficients of thermal expansion and fusibility of the engobes in the development of the central curvature of the tiles the optical fleximeter of heating was used. With the results, it was possible to perceive that the more refractory the engobe in relation to the substrate will be the development of the convex curvature and the more the flux the greater the development of the concave curvature, and the greater the probability of this accompanying the behavior of the substrate until the beginning of the cooling due to the creep mechanism provided by the volume and viscosity of the liquid phases formed during burning. In cooling, the higher the coefficient of thermal expansion of the engobe in relation to the substrate, the greater the development of concave curvature and the smaller the greater the development of the convex curvature.

The aim of the present study was to investigate the physiological and somatic changes, with emphasis on the analysis of effects on cardiovascular function, induced by exposure to chronic stress in normotensive male and female rats. We also investigated the possible vulnerability of spontaneously hypertensive females rats (SHR) to physiological and somatic effects induced by stress protocols. The animals were exposed to 10 days protocols of repeated restraint stress (RRS) and chronic variable stress (CVS) protocols. We observed that control females presented basal HR values higher than males, and this effect was related to higher cardiac sympathetic activity and lower cardiac parasympathetic activity, when compared to males. In addition, both RRS and CVS caused HR increase in males, in which it was related to an increase in cardiac sympathetic activity. However, only RRS increased basal HR in females, in which it was also accompanied by an increase in cardiac sympathetic activity. Both RRS and CVS increased plasma corticosterone levels in females. We observed that both stress protocols decreased body weight gain only in males. In addition, CVS caused adrenal hypertrophy in males. Both RRS and CVS reduced the reflex bradycardia response triggered by increased blood pressure in males. In addition, CVS increased the reflex tachycardiac response triggered by decreases of blood pressure in males. Neither of the chronic stress protocols influenced baroreflex activity in females. Regarding the blood pressure response to vasoactive agents, we observed that the pressor response due to the intravenous administration of phenylephrine was not altered by neither of the chronic stress protocols in both genders. The response of acetylcholine was reduced only by CVS in males and increased by both stress protocols in females. The RRS also increased the SNP response in males, but in females both protocols decreased the response to SNP. As expected, we observed that SHR females had higher baseline blood pressure values than normotensive females. RRS caused an increase in basal heart rate in both normotensive and SHR female rats, in which it was related to an increase in cardiac sympathetic activity. Both chronic stress protocols increased baseline plasma corticosterone levels and reduced body weight gain in both SHR and normotensive females. In addition, CVS and RRS caused hypertrophy of the adrenal glands in normotensive rats and increased thymus weight in SHR rats. In summary, concerning to the influence of sexual dimorphisms, the results indicate that, regardless of the type of stress, males are vulnerable to somatic effects and on body weight, while females appear to be more susceptible to the effects of chronic stress on baseline HPA axis activity. In addition, present findings indicate that females are selectively vulnerable to cardiovascular and autonomic changes evoked by homotypic stressors, whereas homotypic and heterotypic stressors similarly affect cardiovascular function and autonomic activity in males. Regarding an influence of hypertension, the findings did not indicate differences in cardiovascular, somatic and neuroendocrine responses induced by stress protocols in normotensive and SHR female rats.

Increasing levels of eutrophication in aquatic environments favors the appearance and proliferation of cyanobacteria that can produce toxic compounds and exhibit varying levels of toxicity. Microcystins (MCs) are hepatotoxins that can be produced by different species of cyanobacteria, but which can affect other organs. The objective of the present study was to investigate whether the crude extract of Radiocystis fernandoi strain R28, which contains MC-RR and MC-YR variants and small amounts of other oligopeptides, may present fish toxicity (Piaractus mesopotamicus), compromising the osmoregulatory processes in gills and kidneys, as well as liver function. P. mesopotamicus were injected intraperitoneally (ip) with 100 μg of MC-LR equivalent per kg-1 body weight using 0.5 ml of saline solution (NaCl 0.9%) as vehicle and the gills, kidneys and liver were analyzed 6 and 24 hours after injection using biochemical and morphological biomarkers. The respective controls for each time were i.p. injected with 0.5 mL of saline solution. The gills showed no changes in PP1 and PP2A phosphatase proteins and in the kidneys there was inhibition 6 h after injection. A change in ionic balance occurred. In the gills, Na/K-ATPase (NKA) activity increased after 3 h, decreased after 6 h and did not change after 24 h, the activities of H-ATPase (HA) and carbonic anhydrase (CA) were not altered; there was no change in these enzymes. Chloride cells (CC) decreased 3 h after crude extract injection and showed a tendency to increase in the lamellae after 6 and 24 hours. Several histopathologies such as cell hypertrophy, partial lamella fusion, and lamellar epithelial dislocation and disruption were observed in the gills, but no changes occurred in the kidneys. The histopathological and enzymatic changes in the gills after the injection of crude extract of R. fernandoi and the alteration of Na+plasma show that the substances present in the extract influence the ionic homeostasis in fish. Changes in hepatic and cellular architecture, hyperemia, cellular hypertrophy, cellular atrophy, nuclear alterations and, after 24 hours, the increase of intracellular inclusions together with pycnotic nuclei may be indicative of the inhibition of PP1 and PP2A in the liver of cell death. In addition, alterations in plasma levels of alanine aminotransferases (ALT), aspartate aminotransferases (AST), acid phosphatase (ACP) and alkaline phosphatase (ALP) of liver function as well as changes in bilirubin levels indicate impairment and damage to hepatocyte structure . In conclusion, the results suggest that the crude extract of the R. fernandoi cyanobacteria can compromise the osmoregulatory processes with the alteration of the NKA and chloride cells with consequent alteration in the plasma concentration of ions and present hepatic toxicity compromising the function of the liver and being able to affect the health and survival of fish.

This work is the product of a PhD research in Education and focuses on the professional identity of the school’s music teacher. The objectives were: (1) to analyze the identity construction process of the Music teacher, in order to understand the relationships that it establishes with the context of Music Education in Brazilian basic education; (2) understand which are the processes of socialization that influence the construction of the identity of the teacher of Music of basic education; (3) To analyze how different experiences, social relations and contexts influence the identity of Music teachers in basic education. The research question that guided the work was: How is the identity of the music teacher who works in basic school constructed?The key concepts of the research are: Identity, based on the Dubar, Socialization, having Dubar, Berger and Luckman as reference and Culture, based on the productions from Raymond Williams. The methodology is mixed, being bibliographical research, analyzing scientific articles on the subject, and field research, with semi-structured interviews. As data, I analyzed 16 articles from five different countries and interviewed two music teachers, who were admitted to work in the public education system. I concluded with this work that being a musician and being a teacher are two aspects that add up to the professional identity of the Music teacher; that the context, both specific to the classroom and broader: of the city or country in which professionals work, has a strong influence on the formation, consolidation or crisis of the Music teatcher’s identity; and, the recognition and value given by society will open or close the possibilities and potential of musical work in the basic school. The aim of this work is to understand the music teacher’s professional identity in order to contribute with his recognition, his training process and his space of action

Engineered stones, commonly known in Brazil as quartz surfaces, are materials used as large tiles for application in architecture and interior decoration. These materials consist of about 90% by weight of mineral particles of various shapes (usually quartz, but mica and feldspar are also used) dispersed in a polymer resin matrix. Despite its aesthetic appeal, the use of a polymer matrix leads to low wear resistance, low chemical resistance and great possibility of degradation of the polymer by UV rays and permanent marks by contact with hot objects. Thus, this project objective was the development and optimization of compositions and conditions of thermal treatment, characterization and viability of engineered stones with glass instead of a polymer matrix. Glass-mineral composites containing up to 70% weight of albite, alumina, petalilte and quartz (the rest being recycled window glass) were studied, with special attention in obtaining samples with low porosity. The composites were also characterized in relation to some properties, such as flexural strength, hardness, Kc, water absorption, resistance to thermal shock and resistance to chemical attack. With the exception of Quartz / Glass composites, it was possible to obtain materials of low porosity and diverse competitive properties in relation to other products already available. A composition containing glass and alumina had a flexural strength of 115 MPa and a hardness of 9 GPa; The composite of petalite and glass exhibited greater resistance to thermal shock; The albite and glass composite exhibited better resistance to chemical attack practically unchanged even when in contact with solutions of NaOH 10% (v / v), acetic acid 10% (v / v) and citric acid 3 g / L.

The decomposition of a single macrophyte species may not represent entirely the carbon cycling in aquatic ecosystems, once in these environments several species growth and decay concomitantly. To describe the interaction of decomposition, the temporal variation of particulate organic carbon (POC) of Hedychium coronarium, Typha domingensis and the mixed samples (50% of each species) of these macrophytes were analyzed. Kinetic models were used to verify the temperature and the availability of dissolved oxygen, as regulation factors for the in vitro decomposition. Decomposition bioassays were prepared with dry plant fragments and water samples from the Fazzari Reservoir (47 o 53 ́ 15.80 ́ ́W and 21 o 58 ́ 15.19 ́ ́S). The incubations were maintained under aerobic and anaerobic conditions at 15, 20, 25 and 30 o C. From the chemical point of view, the detritus (single plants and the mixed samples) presented heterogeneous characteristics. The mean values of the labile fraction decay coefficients (k LS ) and the refractory fraction (k R ) of POC were parameterized. The POC temporal variation decay of H. coronarium (Treatment I), T. domingensis (Treatment II) and mixed litters (Treatment III) allowed to observe that, in general, aerobic processes favored the faster POC decay. The increasing temperature influenced the POC loss of mass in the three treatments (I: H. coronarium, II: T. domingensis and III: mixed samples). The Q 10 values in aerobiosis were 1.46, 1.55 and 2.00, and in anaerobiosis were 1.03, 1.26 and 2.09, for Treatments I, II and III, respectively. The anaerobic processes presented higher dissolved organic carbon (DOC) yields than the aerobic. The detritus decay in the Treatments I, II and III was % higher in the aerobic conditions. In general, a trend of pH increases during aerobic and anaerobic decomposition processes was observed. Among the 3 treatments, the mixed samples presented lower electrical conductivity values at 15, 20 and 30 o C, in which T. domingensis presented the highest values, however at 25 o C, the highest values were observed for H. coronarium. A tendency of increased enzymatic activity was observed in H. coronarium (aerobic and anaerobic conditions) and in mixed litters (aerobic conditions) as the temperature increases. The average phosphorus content of the remaining POC found in the aerobic and anaerobic incubations of H. coronarium showed the highest values among the 3 treatments, and T. domingensis litters presented intermediate values, as the temperature increased. The highest phosphorus content was found in mixed litters incubations under anaerobic conditions at 30°C. Interactive responses were evaluated in the mixed litter decomposition. Extrinsic factors (i.e. temperature and dissolved oxygen) and the chemical plants composition influenced the mixed samples decomposition processes, being observed antagonistic effects in aerobic incubations, at all temperatures, and, in anaerobic conditions, antagonistic (15 o C), additive (20 and 25 o C) and synergistic effects (30°C) were observed.

Public organizations management has undergone major changes in order to modernize. One way to achieve this goal is to modernize People Management. One approach is People Management by Competencies (PMC). PMC incorporates several concepts such as competency, complexity and occupational space. In Brazil, the Decree no. 5707/06 provided the establishment of policies and guidelines for the development of personnel in the federal public administration, autarchic and foundational, among them the Federal Institutions of Higher Education (FIES) and it allowed the PMC to be put in practice. Minor struggles were encountered when the FIES implemented the PMC, such as: the existence of legal premises that do not include PMC in public admission assessments, career plans, and remuneration progress that are not adequate to this new reality, and especially the non-appropriation of the concepts of complexity and occupational space by the current initiatives. Hiring Administrative Technicians in Education (ATE) through a trial of tests and titles, and the difficulty to map their competencies makes it difficult to maneuver the ATE. Being unsatisfied with their activities, the are more prone to deliver unsatisfactorily, as evaluated by their "clients". The goal of this research was to investigate the concept of complexity applied to work processes in the public context with the purpose of allocating servers in positions compatible with their professional performance. The research method used was action research, and the case was the Federal University of São Carlos (FUSCar). The results obtained comprised a proposal for the lack of a model for the internal movement of personnel, which included the mapping of the work processes and the classification of the server’s performance in these processes in levels of complexity. The theoretical discussion and the results achieved brings us to the conclusion that the use of the concepts of complexity and occupational space empower the employees and managers in their decisions about shifts in the organizational structure, by making them aware of their role and their contribution in the different units of the organization.

Biological invasions are considered the second major cause of biodiversity losses and invasions by exotic grasses constitute one of the most severe cases of invasions in native plant formations, intensely modifying ecosystems functioning. Invasive species change important ecosystem processes such as nutrient cycling, decomposition and fire regimes. According to some authors invasive grasses can alter soil microorganisms, in such way that these become a facilitator to their establishment. This study aimed to compare the abundance and metabolic activity of soil microbiota in the rhizosphere of invasive and native grasses. The research was carried out in the Ecological Station of Itirapina, São Paulo, in four areas being two in “campo cerrado” and two in “campo sujo” plant formation. Two samplings were carried out in the year 2015, one in March, at the end of rainy season and other in September at the end of the dry season. Abundance of microorganisms (bacteria, fungi and protozoans), carbon (C) and nitrogen (N) content in the microbial biomass were quantitatively determined in the soil of the rhizosphere of three species of native (Loudetiopsis chrysothrix, Tristachya leiostachya, e Panicum sp.) and three species of invasive grasses (Melinis minutiflora, Melinis repens e Urochloa decumbens). The metabolic activity (microbial respiration) was measured and a metabolic quotient calculated as an indicator of the efficiency of carbon incorporation into microbial biomass. Physical and chemical characteristics of soil in the rizosphere of all species of grass studied were measured: granulometric soil fractions, temperature, pH, humidity, total C, N, and organic matter concentrations. Significant differences were found when comparing the soil from the rhizosphere of invasive and native grasses in both “campo cerrado” and “campo sujo” formations regarding Fungi density, total carbon and total N in the microbial biomass, total organic C and N in the soil and metabolic quocient. Values of carbon and nitrogen in microbial biomass and also total organic C and N in the soil were higher in native species than in invasive ones. Metabolic quotient values showed high values for invasive than for native grass species, thus indicating that the microbiota in the rhizosphere of invasive species has lower efficiency of carbon incorporation into their biomass, what appears to be a consequence of changes in the rhizosphere of exotic invasive grasses.

The independent cultural manifestation of the digital games, can be for many, a recent phenomenon, that has been brought by the digital distribution and the increasing number of platform; from smartphones and tablets to the videogames of the latest generation. However, delving deeper into the historical bias of independent production we can notice the first experimental manifestation from this medium, outside of the commercial means. Experimentations that celebrate the unrestricted access to computers outside scientists, experimentation that made possible the formation of communities connected online before the advent of the internet, that created ways for hobbyists, amateurs, and new game designers explored a rich means of expression in this medium. Therefore, this study was made in order to obtain an understanding of the evolution in independent production in video games and its complex unfolding. These unfolding allowed that indie games to have different impacts. The first impact analyzed here is the growth of the Brazilian game production, the importance of a low-cost format of production moved by creativity and the shaping of a strong independent movement in Brazil. The other impact analyzed is the recurrent phenomenon that blurs the line between mainstream and indie. This work aimed to study this phenomenon under the lens of the complex game No Man’s Sky, made by a small and unknown independent studio called Hello Games. Hello Games became infamous in the game industry due to the problematic launch of No Man’s Sky, one of the most anticipated titles of 2016 that failed to meet the expectations of the players. It was then analyzed the artistic approach, narrative, interactivity and technical complexity of No Man’s Sky in other to comprehend how a small studio was capable of creating 18 quintillion planets.

Precision Agriculture (PA) is an agricultural cultivation strategy which uses technologies and principles to manage the spatial and temporal variability related to all aspects that surround a crop, in order to increase yield in a sustainable way, enabling both the reduction of environmental risks and the increase of profits. One of the processes used by this strategy to achieve this goal is the delineation of the crop area in smaller plots with similar characteristics, known as differentiated management units (DMUs). In order to achieve success in this process, dissimilarities between the DMUs must be properly identified from spatial data collected through field or remote sensors. Therefore, the delineation of DMUs may be considered as a spatial data clustering oriented process, in which a clustering solution corresponds to a map of DMUs. The computational approaches found in literature in order to assist in automating this process, usually based in fuzzy clustering algorithms, do not consider, for the most part, the geographic coordinates which compose the collected samples during their methods execution, which can make the DMU maps overly stratified. Therefore, it is possible to observe the lack of a consensus approach in the literature which may allow expert users to obtain DMU maps with minimum internal variability and which, at the same time, are easily interpreted by expert users. Given the above, the process for the delineation of DMUs in PA is discussed in this thesis, whose main contributions are: (i) the SD-Spatial internal validation criteria, which considers issues related to clusters cohesion and separation both in the attribute space and in the coordinate space; (ii) the SWMU Clustering spatial clustering approach, which explores in a weighted way the dissimilarities of the conventional and spatial attributes, using parameters provided by the expert user without the determinism of the solutions being impaired; and (iii) the complementary approach SWMU Polygon, which allows to represent the DMU maps in polygonal shape. Based on the experiments, the SWMU Clustering approach presented average gains of 31.94% in the validation measure considering both the attribute space and the coordinate space, in comparison to approaches using fuzzy clustering; and the complementary approach SWMU Polygon provided average performance gains of 61.14% in the retrieval of DMU maps stored in spatial databases.

In this thesis, we present a concrete methodology to calculate the epsilon-optimal controls for non-Markovian stochastic systems. A pathwise analysis and the use of the discretization structure proposed by Leão and Ohash jointly with measurable selection arguments, allows us a structure to transform an infinite dimensional problem into a finite dimensional. In this way, we guarantee a concrete description for a rather general class of stochastic problems.

The main objective of this research was to construct guidelines for a future formulation of policies of access and permanence for students from disadvantaged economic sectors, based on the current legislation, that intend to enter in the courses of master academic and doctorate. This was done through the collection of information on the lattes platform and on institutional sites, both of free access, and also through questionnaires applied to undergraduate and graduate coordinators. It was also part of this objective to verify what are the current institutional policies geared specifically to graduate students. Finally, the following proposals for guidelines for actions for access were elaborated: a) Increased dissemination of UFSCar's research groups to motivate undergraduate students to join these groups; b) Offer of language courses for UFSCar undergraduates who wish to enter the master's and doctoral courses; c) Assistance in the elaboration of research projects, both at the undergraduate level (CI projects) and at the postgraduate level (Master's projects, mainly). Actions for permanence: d) Improvement of UFSCar infrastructure to meet people with special needs; e) Encouraging the active participation of postgraduate students in the discussions involving scholarship, housing, food and transportation; f) Expand the offer of scholarships that take into account socio-economic criteria, in addition to the academic criteria. For both of them: g) To create spaces for discussion at UFSCar that deal with the problems of access and permanence in postgraduate courses of students from economically disadvantaged social strata, involving teaching staff, technical-administrative staff, undergraduate students and graduate students.

Resistance training is characterized by the action against a resistance leading to a muscular stress, which can be generated by different methods, be they maximum, until the concentric failure or submaximal, finalized series before the concentric failure. In relation to the energy expenditure (EE), the literature suggests that there may be a point of proximity of the concentric failure in which the energy metabolized to the execution of each repetition becomes higher, even with the maintenance of the intensity. Another important aspect is the level of muscle injury determined by creatine kinase (CK), an indirect marker of muscle injury induced by exercise, however, the literature does not present studies comparing the blood CK response to RT with and without concentric failure. soon this study proposed to analyze the GE and the muscular damage in the conditions according to the protocol of 3 sessions of training with different volumes and weight of 20RM in 9 men trained and untrained. The energetic GE was measured by the collection of expired gases (aerobic component) and the anaerobic component was determined by the product of lactate variation (Δlac) by body weight, with Total expenditure being the sum of these two. Kinetics of blood CK were determined in collections performed before and 24h, 48h and 72h after each session. All data were analyzed using the software Statistic 7, normality was analyzed by the Kolmogorov- Smirnov test e homogeneity by Levene, a two-way analysis of variance (ANOVA) with Tukey post-hoc was used for parametric variables and nonparametric variables were analyzed by Kruskal Walls ANOVA. Comparisons between groups were made with t student test. Significance level was established at 5% (p<0.05). The IFMR was significantly higher in all exercises for the trained group. In the 3 training sessions, trained group performed the higher training volume. Regarding EE, the untrained group has no difference between the 3 sessions while the trained group had higher EE in the 20rep session compared to the other sessions. CK kinetics peaked at 48h for all groups and training sessions and the highest values were found after 16rep for the untrained and 20rep for the trained. Since the CK / rep was higher in the sessions closer to the concentric failure.The result of the present study showed that it is not necessary for the untrained individuals to perform maximal training to obtain higher EE because they lose efficiency during training, which may have been due to a failure in the inter and intramuscular interaction that occurs through neural adaptation to training. For the trained individuals, the increase in the number of repetitions per series is an efficient strategy for the increase of the EE, since there is an increase of the expense that is closer to the failure, which was observed when analyzing the EE / rep. The CK concentration analysis also showed that there is no difference in the level of training, but it is larger the closer to failure. In addition, it is important to observe the peak of 48h for prescription of similar protocols.

Student satisfaction is a response from the student evaluation regarding several aspects of the educational experience. The objective of this study is to investigate the effects of service quality, learning outcomes, employability, value and institutional image on the satisfaction of students enrolled in Vocational Education, considering the multiple relationships between the mentioned factors and the impacts on the student loyalty. A conceptual model was proposed that differs from others because it adds two important constructs for the educational context - learning outcomes and employability. Both are especially relevant in Vocational Education. For the validation of the model, a quantitative survey was carried out with students enrolled in courses offered by the Federal Institute of Education, Science and Technology of São Paulo. A valid sample of 505 students was obtained. The data were analyzed using Structural Equation Modeling The results showed that the final model has a large capacity to explain the variation in factors related to student satisfaction. It was identified that educational quality of services and employability have the greatest effects on student satisfaction. While the value that the student attributes to the educational experience is mainly determined by learning outcomes. Theoretical and managerial implications are made.

The service sector has gained prominence both in the Brazilian and in the world’s economies, impelling organizations to seek excellence in their service. Faced with this need, in the banking sector, institutions have emphasized a mutually beneficial relationship with their clients, in order to make the management of services a competitive differential. Service quality and customer satisfaction have been identified as key factors for competitiveness and customer retention. In this context, there is a challenge in understanding the relationships among the antecedent factors of customer satisfaction. In fact, previous research agrees neither on the direction nor on the degree of relationship of these factors, besides being studied in different countries and service sectors. Thus, the purpose of this study is to investigate the multiple relationships among the constructs – service quality, perceived value, corporate image and customer satisfaction. For that, a literature review was carried out on the concepts pertinent to this research; the constructs were conceptualized individually, providing the theoretical basis for their operationalization. Then, the relations among them were evidenced by the statement of hypothetical links, thus specifying the theoretical model. After articulating the knowledge in a theoretical manner, in the city of Sorocaba-SP, a survey was conducted, using a questionnaire randomly applied to 136 clients of the banking services, which use at least one of the five largest Brazilian banks. Data analysis was performed through the structural equation modeling technique, in order to test the consistency of the hypotheses and to identify the direction of the relations. The results showed that service quality directly influences the perceived value and the corporate image and that the image directly impacts customer satisfaction, making it a potential mediating variable for the quality-satisfaction relationship. The direct relationship between quality and satisfaction as well as perceived value and satisfaction were not observed, considering the sample of this research and the levels of significance. Therefore, this study might be both theoretically and practically relevant. Such knowledge directs banking institutions to prioritize the allocation of resources and efforts on the corporate image. Through this factor, the expected implications related to customer satisfaction will be achieved directly. Simultaneously, banks must acknowledge that the delivery of high quality is an important driver of corporate image and perceived value. In the academic field, the study develops architecture of measurable indicators making it possible to evaluate the proposed constructs, besides constructing an explanatory theory in the understanding of the relations among them for the banking sector.
