The research identifies and describes the principles and methodological procedures of the director Gilles Gaetan Gwizdek on the transposition of the dramatic text to the space of representation through action and movement. Besides that, it presents the results of the experiment in two different labor camps and conducting modes: the no-actor student, inserted into the basic education, and the actor-student, inserted in higher education. Through the scenic paths encountered by the director, the individuals were could find their own ways and verify, through the scenic conductions, how such methodological procedures can achieve a pedagogical thinking about the actor's work. As theoretical referential, were studied the artists-educators: Jacques Copeau, in what sensitizes to the use of dramatic text, and Jacques Lecoq, it approaches of the physical use of the actor's body to the theater. The concepts about theater of the scholars in theater: Constantin Stanislavski, Eugênio Barba, Meyerhold, Eugênio Kusnet, Bertold Brecht go through the theoretical revisions of the thinkers: Odete Aslan, Patrice Pavis, Ney Piacentini, Lúcia Romano, Flávio Desgranges e Anne Bogart, in what affects their practical experiences and conceptual about the text, the action and the movement. It was analyzed also the practical experience based on the principles and methodological procedures of Gilles director, in rehearsals and performances of students in the ninth grade of the primary school the Basic School of the Federal University of Uberlândia - ESEBA, as also, of the students of the sixth, seventh and eighth period, of the Theater Graduation in the same university. From this analysis, it was proposed an interrelation between the theoretical and practical works, done by reading of the artists-educators about movement and Gilles Gwizdek in his work process. The research suggests that, from the movement, the student can build autonomously a character through the experience of small movements of the body. Thus, this student would increase his relationship between stage and audience, and consequently, he would cause a possible state of "seduction" of the spectator to the spectacle.

One of the most common forms of reuse is through API usage. However, one of the main challenges to effective usage is an accessible and easy to understand documentation. Several papers have proposed alternatives to make more understandable API documentation, or even more detailed. However, these studies have not taken into account the complexity of understanding of the examples to make these documentations adaptable to different levels of experience of developers. In this work we developed and evaluated four different methodologies to generate tutorials for APIs from the contents of Stack Overflow and organizing them according to the complexity of understanding. The methodologies were evaluated through tutorials generated for the Swing API. A survey was conducted to evaluate eight different features of the generated tutorials. The overall outcome of the tutorials was positive on several characteristics, showing the feasibility of the use of tutorials generated automatically. In addition, the use of criteria for presentation of tutorial elements in order of complexity, the separation of the tutorial in basic and advanced parts, the nature of tutorial to the selected posts and existence of didactic source had significantly different results regarding a chosen generation methodology. A second study compared the official documentation of the Android API and tutorial generated by the best methodology of the previous study. A controlled experiment was conducted with students who had a first contact with the Android development. In the experiment these students developed two tasks, one using the official documentation of Android and using the generated tutorial. The results of this experiment showed that in most cases, the students had the best performance in tasks when they used the tutorial proposed in this work. The main reasons for the poor performance of students in tasks using the official API documentation were due to lack of usage examples, as well as its difficult use.

The increasing demand in electricity and decrease forecast, increasingly, of fossil fuel reserves, as well as increasing environmental concern in the use of these have generated a concern about the quality of electricity generation, making it well welcome new investments in generation through alternative, clean and renewable sources. Distributed generation is one of the main solutions for the independent and selfsufficient generating systems, such as the sugarcane industry. This sector has grown considerably, contributing expressively in the production of electricity to the distribution networks. Faced with this situation, one of the main objectives of this study is to propose the implementation of an algorithm to detect islanding disturbances in the electrical system, characterized by situations of under- or overvoltage. The algorithm should also commonly quantize the time that the system was operating in these conditions, to check the possible consequences that will be caused in the electric power system. In order to achieve this it used the technique of wavelet multiresolution analysis (AMR) for detecting the generated disorders. The data obtained can be processed so as to be used for a possible predictive maintenance in the protection equipment of electrical network, since they are prone to damage on prolonged operation under abnormal conditions of frequency and voltage.

This research is the result of research at the level of Master of the Graduate Program in Education of the Federal University of Uberlândia – PPGED/UFU, inserted in the line of research "State Policy and Management in Education." Its object of study International Degree Programme – PLI established officially in 2010, the Higher Education Personnel Improvement Coordination – Capes, in particular the PLI at UFU. The overall objective is to describe and analyze the implications, while limits and possibilities of its implementation in UFU in the 2010-2012 period, from the context of the internationalization of higher education and educational policies in this area. They were used as data collection instruments, bibliographical, documentary research and semi-structured interview applied to the former rector of the UFU, managers, engineers, teachers and students participating in the PLI/UFU 2010-2012. For the data analysis, the theoretical and political aspects influencing policies for teacher training, as well as the legal PLI documents were considered. As a result, on the one hand, it was found that the PLI, in the context of UFU, gives opportunity to the participants the possibility of holding courses abroad, contributes to their personal and cultural background. On the other hand, the PLI would not be, in fact, academically contributing to improve vocational training as its main objective, but rather, for what happened in Portugal over the three issues considered, it would have contributed to reaffirm, among the students, political will to not act as teachers in the context of basic education.

Lung cancer is the most common of malignant tumors, with 1.59 million new cases worldwide in 2012. Early detection is the main factor to determine the survival of patients affected by this disease. Furthermore, the correct classification is important to define the most appropriate therapeutic approach as well as suggest the prognosis and the clinical disease evolution. Among the exams used to detect lung cancer, computed tomography have been the most indicated. However, CT images are naturally complex and even experts medical are subject to fault detection or classification. In order to assist the detection of malignant tumors, computer-aided diagnosis systems have been developed to aid reduce the amount of false positives biopsies. In this work it was developed an automatic classification system of pulmonary nodules on CT images by using Artificial Neural Networks. Morphological, texture and intensity attributes were extracted from lung nodules cut tomographic images using elliptical regions of interest that they were subsequently segmented by Otsu method. These features were selected through statistical tests that compare populations (T test of Student and U test of Mann-Whitney); from which it originated a ranking. The features after selected, were inserted in Artificial Neural Networks (backpropagation) to compose two types of classification; one to classify nodules in malignant and benign (network 1); and another to classify two types of malignancies (network 2); featuring a cascade classifier. The best networks were associated and its performance was measured by the area under the ROC curve, where the network 1 and network 2 achieved performance equal to 0.901 and 0.892 respectively.

Health promotion is opposed directly to the biomedical model and established by intersectoral action, with collective and interdisciplinary approaches, considering the subject in their life contexts. Build healthy territories is to promote health, which necessarily includes intersectoral coordination and community mobilization. The health and education sectors can work together to promote health, developing so articulate actions and practices involving the subject in its territory of life and work. This study aimed to design and experience of health promotion strategies in school and Basic Health Units Family in Uberlândia - MG, from intersectoral relationship and community mobilization. The methodological research route was action research, or research intervention, because while researching already applied the ideas to solve problems through collective action. The research began in the Municipal School of Basic Education Prof. Eurico Silva, with the Health Centre's deployment to carry out surveillance and health promotion with active participation of students, involving all subjects of the school, students, teachers and other staff in the context of everyday life, which extrapolates the school walls, reaching the family and social groups in the community to which they belong. The health observatory has the objective existence with the establishment of the working groups, which at first were "healthy eating" and "drug-free world" and later, "dengue". The themes were chosen by the participants of the Health Centre, in which each is involved preferably. The second part of the research started with the approach between the Centre for Health and the health units (UBS and BFHU). The proposal was that the schools and the health nurse unit together should undertake prevention and health promotion, combating Aedes aegypti with intersectoral coordination and community mobilization. For it was crucial the involvement of ACS, ACE, ASE and the nurse coordinator of the Health Unit in creating community networks in the territory. home visits, community mobilization and intersectoral coordination: a training course in all BFHU and UBS teams with the following subjects was conducted. At this stage, were the Health Units that should approach the schools, in order to provide community networks to fight Aedes aegypti in each territory. The results and the scope of this experiment could only be brought to fruition because the Board of Health Surveillance and Care Coordination council of Basic embraced the proposal and helped in its implementation. It remains to continue consolidating this process of work in health units of primary care and the elementary schools, replicate the Health Centre's experience at school. The conclusion of this work is that schools and care facilities to health together with intersectoral coordination and community mobilization supported by community networks, can carry out prevention and health promotion, from a health model that considers the social determinants of health and overcoming hygienist model / sanitarian.

Nowadays, the amount of customers using sites for shopping is greatly increasing, mainly due to the easiness and rapidity of this way of consumption. The sites, differently from physical stores, can make anything available to customers. In this context, Recommender Systems (RS) have become indispensable to help consumers to find products that may possibly pleasant or be useful to them. These systems often use techniques of Collaborating Filtering (CF), whose main underlying idea is that products are recommended to a given user based on purchase information and evaluations of past, by a group of users similar to the user who is requesting recommendation. One of the main challenges faced by such a technique is the need of the user to provide some information about her preferences on products in order to get further recommendations from the system. When there are items that do not have ratings or that possess quite few ratings available, the recommender system performs poorly. This problem is known as new item cold-start. In this paper, we propose to investigate in what extent information on visual attention can help to produce more accurate recommendation models. We present a new CF strategy, called IKB-MS, that uses visual attention to characterize images and alleviate the new item cold-start problem. In order to validate this strategy, we created a clothing image database and we use three algorithms well known for the extraction of visual attention these images. An extensive set of experiments shows that our approach is efficient and outperforms state-of-the-art CF RS.

This work aimed to analyze the so called June Journeys which happened in Brazil in 2013, in an effort to establish a proper ontology for cyberspace that goes beyond old dichotomies that put men and techniques in polar opposites, making difficult to perform a constructive – and not merely pessimist – analysis of the crossroads between politics and technology. This analysis uses as basis and methodological guidance the Theory of Actor-Network (ANT or TAR) widely used in social studies of science and technology to overcome these dichotomies and allow the analysis of networks, so that is clear the political instability that arises in this context which profoundly changes the political game.

Urban violence, manifestly public and free, has changed the standard of sociability of townspeople. The city is an increasingly private space of hopes of reducing the risk of victimization, due to the fear of violence that separates and distances the classes in expectation of concealing this behavior. However, violence has many facets and, in one way or another, will always be present as a product of social friction. It is in the urban context and using drug trafficking as a backdrop that this work raises questions about the territorial violence in Montes Claros - MG. The objective was to analyze the dynamics of illicit drug trafficking from the concepts of territory, observing to what extent the appropriation of space contributes to the use of violence, especially in interpersonal disputes. Methodologically, it seeks from quantitative and qualitative techniques make the spatial distribution of criminal indicators, defining and creating hierarchy territories of violence in urban areas. From the qualitative approach seeks to organize and analyze data together to the Civil and Military Police, Brazilian Institute of Geography and Statistics -IBGE, João Pinheiro Foundation and the System of the Ministry of Health Mortality Information - SIM. The opportunity of miscegenation between the knowledge of the survey respondents and the official data has introduced qualitative part. The city of Montes Claros has been taken as an object of observation due to a set of conditions, which stood its medium size, your importance in the regional context and their socioeconomic disparities. The results point to the existence of multiple territoriality of violence involving the trafficking of illicit drugs in urban space. Territorial disputes by the traffickers have victimized people with socioeconomic characteristics and urban spatial origin similar. The dynamism of the established boundaries from the cohesion and / or rupture of the interests of those involved creates and destroys territories in the power struggle.

This paper analyses the sustainability under the environmental (ecological) perspective of Water Supply and Sanitary Sewers Systems from Uberaba city, MG. It was accomplished in this analysis, An Environmental Sustainability Assessment of those systems, by the means of specific sustainability indicators proposed for Uberaba, but which may be used for other simi-lar cities. To the characterization of the systems, visitations were made to the main units as well as a documental was elaborated. The definition of the level or stage of the sustainability by the indicators was made based on a literature review, on interviews with the technicians and managers of the systems and based on the characterization and observation of the system reality, being attributed to them the following classification: Non Sustainable, Low Sustaina-bility, Medium Sustainability and High Sustainability. It was verified that the indicators that have lower compatibility to the process of sustainability to the studied systems are those rela-ted to the water physical losses, to the water per capita consumption, to the electricity con-sumption and to the sludge from the water treatment plants disposal untreated into a water body, for the Water Supply System. And those ones related to the attendance with sewage treatment, to the electricity consumption and to the usage of the treated sewage, for the Sani-tary Sewers, all of them classified as Non Sustainable.

Arachidonic acid (AA) a precursor in the formation of eicosanoids which are lipid mediators with a number of functions in human physiology and pathology. The most of the eicosanoids act as proinflammatory mediators and contribute to the development and proliferation of tumors. In this thesis we evaluated two mediators: 15-deoxy-Δ12,14-PGJ2 (15d- PGJ2) and epoxieicosatrienoic acids (EETs) both act with an opposite activity of most eicosanoids, with an anti-inflammatory and and anti-tumoral action these two distinct mediators from AA pathway were used in this thesis in two different projects. First: 15d- PGJ2, was described that to have an antiproliferative activity and to induce apoptosis in several types of tumor cells however, the effect of 15d- PGJ2 in thyroid cancer cells was unknown in this sense, we tested in vitro cultured thyroid tumor cells, here in TPC1 cells, and treated with different concentrations of 15d- PGJ2 (0 to 20 uM) the treated cells showed a decrease in proliferation and an increase in apoptosis and a decrease in IL-6 release and relative expression. These key results together demonstrate that 15d- PGJ2 can be used as a new therapy for thyroid cancer. Second: The EETs are converted to their diols by soluble epoxy hydrolase (sEH) to maintain the stability of EETs and their anti-inflammatory activity, an inhibitor (TPPU) against was used to sEH in a periodontitis model induced with Aggregatibacter actinomycetemcomitans. The oral treatment in mice with TPPU and sEH Knockout animals showed bone loss reduction accompanied by a decrease in the osteoclastogenic molecules, like RANK, RANKL and OPG, demonstrating that pharmacological inhibition of sEH may have therapeutic value in periodontitis and inflammatory diseases that involve bone resorption.

The content-based image retrieval is important for various purposes like disease diagnoses from computerized tomography, for example. The relevance, social and economic of image retrieval systems has created the necessity of its improvement. Within this context, the content-based image retrieval systems are composed of two stages, the feature extraction and similarity measurement. The stage of similarity is still a challenge due to the wide variety of similarity measurement functions, which can be combined with the different techniques present in the recovery process and return results that aren’t always the most satisfactory. The most common functions used to measure the similarity are the Euclidean and Cosine, but some researchers have noted some limitations in these functions conventional proximity, in the step of search by similarity. For that reason, the Bregman divergences (Kullback Leibler and I-Generalized) have attracted the attention of researchers, due to its flexibility in the similarity analysis. Thus, the aim of this research was to conduct a comparative study over the use of Bregman divergences in relation the Euclidean and Cosine functions, in the step similarity of content-based image retrieval, checking the advantages and disadvantages of each function. For this, it was created a content-based image retrieval system in two stages: offline and online, using approaches BSM, FISM, BoVW and BoVW-SPM. With this system was created three groups of experiments using databases: Caltech101, Oxford and UK-bench. The performance of content-based image retrieval system using the different functions of similarity was tested through of evaluation measures: Mean Average Precision, normalized Discounted Cumulative Gain, precision at k, precision x recall. Finally, this study shows that the use of Bregman divergences (Kullback Leibler and Generalized) obtains better results than the Euclidean and Cosine measures with significant gains for content-based image retrieval.

The main aim of this research was to study pluviosity in the Paranaíba Riverbasin, especially concerning the variability frame and trends. For this end, we used data from 22 pluviometric stations of the Agência Nacional da Águas- ANA(National Water Agency)spatially distributed throughout the basin area. The data comprised the years 1979-2013, which is a historical series of 35 years, and was downloaded through the ANA website and tabulated using the Hydro 1.2 software (2015) and Excel. After tabulation process were applied based methodologies for statistical analysis of annual variability, monthly, daily and seasonal rainfall in the basin beyond the trend analysis. Results of this research showed that the annual rainfall averageis 1491 mm. Seasonality is a hallmark and rainfall variability occurs spatially and temporally. Rains are accumulated in the rainy season accumulating 85% of the annual volume in the basin. In daily analysis it was found that the daily rainfall above 30 mm occur in only 3% of the time. Dry season comprises 15% of the rainfall. Trend analysis using linear regression pointed to a downward trend in rainfall in 46% of jobs, stability in 18% of posts and increased rainfall by 36%. As for the analysis using the sign test indicated that 32% of the analyzed rainfall stations showed an increasing trend of rainfall over the time series and 68% of stations showed downward trend. This research is important because shows how rainfall worksin the area of the Paranaiba basin, and may be used to develop better management of natural resources and the area through public policies for this purpose.

The coexistence of gingival recession (GR) with root coverage indication and non-carious cervical lesions (LCNC) generates the need for a protocol that respects and promotes health of dental and periodontal tissues and allows treatment predictability. The main objectives of this theses were: (1) verify, through clinical evaluations, the connective tissue graft for root coverage on direct and indirect restorations made of ceramic resin; (2) analyze the influence of the battery level of the LED curing unit in the composite resin characteristics; (3) assess the influence of restorative materials, composite resin and ceramics, on the viability of gingival fibroblasts from primary culture. Nine patients with good oral hygiene and occlusal stability diagnosed with LCNCs the anterior teeth including premolars associated with gingival recession (class I and II of Miller) and only gingival recession were selected. After initial clinical examination, occlusal adjustment was performed and the patients had their teeth randomized allocated on direct composite resin restoration of LCNC, polishing and GR treatment with connective tissue graft and advanced coronally flap CR group (n = 15); and indirect ceramic restoration of the LCNC's and GR treatment (CTG+CAF) Group C (n = 15). The GR presented teeth with no clinically formed LCNCs cavity were treated using (CTG+CAF) being the control group (n = 15). Sorption and solubility tests, analysis of the degree of conversion and diametral tensile strength were performed in composite resin samples (n = 10) photoactivated by 100, 50 and 10% battery charge LED unit. The viability of fibroblasts on composite resin, ceramics and dentin disks (n = 3) was examined. Clinical follow-up was performed for three months. The data obtained at different stages were tabulated and subjected to analysis for detection of normal distribution and homogeneity. The results showed that: the LED unit with 10% battery affects the characteristics of the composite resin; restorative materials present biocompatibility with gingival fibroblasts; and the association of surgical and restorative treatment of teeth affected by NCCL and GR presents successful results at 3-month follow-up.

The theoretical and experimental developments in the biomaterials area have been directly applied to different fields of Medicine (odontology, regenerative medicine and radiotherapy). These advances have focused both for diagnosing diseases such as for quantifying degrees of progression. From the perspective of these studies, biomaterials are being designed and manufactured for application in various areas of science, provided advances in diagnostic radiology, radiotherapy dosimetry and calibration of radiotherapy equipment. Develop a phantom from a biomaterial has become a great ally of medicine in the treat patients with oncological diseases, allowing better performance of the equipment in order to reduce damage to healthy tissue due to excessive exposure to radiation. This work used polymers: chitosan and gelatin, for making the polymeric structures and controlled for different types of production and processing, characterizing and evaluating the biopolymer by physical techniques (STL, SEM and DEI) and therefore analyze applicability as phantom mouse lung. It was possible to evaluate the morphology of biomaterials quantitatively by scanning electron microscopy associated with imaging technique. The relevance of this work focuses on developing a phantom from polymeric biomaterials that can act as phantom providing high image contrast when subjected to analysis. Thus, the choice of DEI technique is satisfactory since it is an imaging technique of X-ray high resolution. The images obtained by DEI have shown the details of the internal microstructure of the biomaterial produced which have ≈ 10 μm dimension. The phantoms had made density ranging from 0.08 a 0.13 g/cm3.
