This paper studies the Brazilian cinematography corporation political joint between 1999 and 2003. Starting from fiscal renounce model crisis in the national film production, wherein the dialog narrowing between filmmakers and the State led to the creation of the National Cinema Agency (Ancine), which generated the cinematographic group split concerning the agency link in the federal organization chart. In this context, I analyze the problems showed by the filmmakers to the sector sustainability and the possible solutions for this, including its limitations inside the scenario involving the cinematographic corporation, the State, the foreign distribution companies and national broadcasting companies. To do this research, it was used books, articles, internet site information, congress documents, federal legislation and interviews to set up the Brazilian cinema political joint development and its problems to execute the sector demands oriented to the sustainability.

In his retiring Presidential address to the American Mathematical Society in 1971, Zariski proposed some questions in the Theory of Singularities. One of them concerns the topological invariance of the multiplicity of complex hypersurfaces. In more accurate terms, Zariski asked: if two complex hypersurfaces are homeomorphic as embedded varieties, then are their multiplicities at the origin the same? The multiplicity of a complex hypersurface at the origin is the number of points of intersection of the hypersurface with a generic complex line passing close to the origin, but not through it. The problem still remains unsolved. However, there are some special cases which were answered affirmatively, such as the case of homeomorphic hypersurfaces by a bilipschitz homeomorphism. This work aims at understanding the main results settled for the problem. In the present dissertation, we will make a precise concept of multiplicity of a complex hypersurface and we will give special emphasis to C1-invariance of the multiplicity, bilipschitz invariance and quasihomogeneous hypersurfaces. Besides having great importance by themselves, these cases bring their own interpretations of multiplicity helping us to understand better such an object.

In this work we consider the long-term survival model introduced by Berkson & Gage (1952), for modeling survival data of nonhomogeneous populations, where a subpopulation does not present the event of interest, despite a long follow-up period. The cure rate models presented in the literature usually are developed under the assumption that censorship is noninformative. In the usual survival models Lawless (1982) considers that the variable of censoring is informative if its density function and its distribution function involve some parameter of interest. We propose a new definition of informative censoring in a similar way. This de_nition is extended for the unified long-term survival models (Rodrigues et al., 2009). Moreover, we verify, with simulated data, the impact caused by informative censoring in the coverage probabilities and in the lengths of asymptotic confidence intervals of the parameters of interest. A Bayesian approach with Jeffreys prior is also proposed. An example with real data is analysed.

Air-breathing fish are classified as obligatory (when breathing obligatory atmospheric air independently of the water O2 tension) or facultative air-breather (using an air breathing organ ABO -, when theirs gills are not able to extract all O2 necessary to maintain the aerobic mechanisms under hypoxic conditions). The catfish, Clarias gariepinus, is airbreathing fish that shows modifications on the gill lamella, forming a ventilatory fan, and on the 2o e 4o gill arches, forming an arborescent organ. These structures form the ABO of this specie.The objectives of the present study were: 1. To determine if C. gariepinus is an obligatory or a facultative air breather. 2. To analyze the cardio-respiratory responses ( VO2 - metabolic rate; VG - gill ventilation; VT ventilatory volume; fR respiratory frequency; EO2 O2 extraction from the ventilatory current; fH- heart frequency) in response to progressive hypoxia. 3. To verify if the critical O2 tension (PcO2) of this specie is correlated with the O2 uptake from the atmospheric air.To classify the air-breathing mode of C. Gariepinus, the fish (Wt ~ 350 g; n = 7) were maintained in normoxia during 24 hours without access to air. The fR maintained constant during all the experiment and there was no mortality, indicating that C. gariepinus is a facultative air-breather. To analyze the cardio-respiratory responses to progressive hypoxia, VO2 , EO2, fR, VT, VG , EO2 and fH were recorded under the following water O2 tensions(PwO2): 100, 70, 50 e 30 mmHg. Fish maintained a constant VO2 until the PcO2 (~ 55 mmHg), below which VO2 decreased significantly. This decreasing was followed with the significant reduction of EO2 in PinspO2 of 62,7 ± 1,30 mmHg reaching values of 19,6 ± 1,9 % in severe hypoxia. The VG and the VT increased progressively until PinspO2 of 28,0 ± 0,5 mmHg, reaching highest values of, respectively, 1545,7 ± 63,5 mLH2O.kg-1.min-1, 33,9 ± 0,8 mLH2O.Kg-1.resp-1 e 57,2 ± 1,4 resp.min-1. The fH reduced progressively from 43,4 ± 0,4 bpm, in normóxia, arriving significant values just above the PcO2 and reaching minimum values (19,2 ± 3,0 bpm) in severe hypoxia. Under progressive hypoxia (100, 70, 50, 30 e 20 mmHg) and with the access to the atmospheric air, C. gariepinus (Wt ~ 610 g; n = 9) presented a 5-fold increase in the air-breathing frequency (fRA). A bradycardia was observed just before the air breath and a tachycardia just after.Concluding, C. gariepinus is a continuous facultative air-breathing fish that regulate the 2 O V until the PcO2 of ~54 mmHg. Below this tension fish increase the VG mainly due to a larger increase of VT (lower metabolic cost of VG ). The hypoxic pre-air breath bradycardia is characteristic of aquatic breathers while the post-air breath tachycardia is typical of air respirators. The fRA increased proportionally with the progressive hypoxia, mainly just above the PcO2. These results show that C. gariepinus is adapted to survive at hypoxic habitats and that this species show a higher dependence of the atmospheric air than the others facultative air-breathing fishes.

For decades the search for determinants of biodiversity and structuring processes of natural communities has been concentrated on the role of environmental factors and differences in species niche. The neutral theory of biodiversity challenged this view by assuming functional equivalence between species and a major role of stochastic spatial processes. In this thesis, I aimed at analyzing how local and regional ecological processes interact to influence the structure of aquatic metacommunities. The thesis has three chapters. In the first one, I investigated one of the most widespread patterns in ecology, the relationship between species local abundance and regional distribution. I used niche characteristics, estimated independently from local and landscape metrics, to explain the relationship. In the second chapter, I tested whether common and rare species are influenced by environmental and spatial processes in a different manner. In the last chapter, I tried to identify taxon association within the Chironomidae that occur in São Paulo State. Besides, I built ecological models considering information from environmental and spatial processes at different scales aiming at predicting theses associations. In general, I conclude that to understand the dynamics of aquatic metacommunities one must include local, landscape and spatial variables in the analyses. Furthermore, it seems that some species do not differ in their realized niches. In other words, they occupy parts of the environmental gradient in a similar way, thus they respond in a similar way to the same type of ecological processes. This opens an avenue for monitoring and conservation programs. For example, we can use a reduced number of species to monitor entire communities. In my opinion, now we need to advance the way we measure and include spatial processes like dispersal in our models.

The World Health Organization (WHO) recommends performing regular physical activities as a way to combat the population inactivity. In São Carlos-SP municipality such activities are promoted by the health units and generate a large amount of data that needs processing. The aim of this work are to develop and evaluate an information system for managing physical activity data of the population enrolled to the São Carlos-SP health units, allowing for the generation of health and performance indicators, which will support the planning of public policies for the promotion of physical activity. Qualitative researches and field observations were conducted in order to capture the system requirements, and quantitative researches were done for its evaluation. This system was developed in Java using the Netbeans IDE 6.7.1. tool, and has interfaces that allow the management of the health units, physical activity groups, physical activity sessions, participants, and the caregivers responsible for these groups. For evaluating the system interfaces and usability, SAM questionnaires were applied to caregivers, with the following results: 84.44% for Satisfaction, 78.89% for Motivation, and 92.22% for Control Sense. For evaluating other system characteristics, a QUIS based questionnaire was applied to these same caregivers, with the following results in a 1-5 scale: 4.0 for Ease of Use, and 4.6 for Utility. This system has proved to be useful and easy to use, and its main contribution is to support the WHO recommendation for the practice of regular physical activity, since it provides the computational means for the effectiveness evaluation of physical activity groups of the São Carlos-SP health units.

The purpose of this research is to analyse the participatory construction of the technological space of a solidarity economy organization of production and commercialization of Brazil nuts integrated by inhabitants of riverside communities of the Lower Madeira River, in Rondônia. The restore of household extractive economies is one of the proposals of forest peoples social movements to match life quality improvement and environmental conservation. This opposes to the hegemonic model of development of the Amazon Rainforest region, based on technocratic state intervention, which is responsible for the harsh social and environmental crises that hit the region and which has in the expel of.traditional forest people from their home lands one of the most perverse effects. New extractive economies have two features that also oppose the early rubber tapping period. Firstly it is based on democratic work relations, what suggest a connection with solidarity economy movement. On the other hand, it purposes it should incorporate new technologies which would radically improve productive forces, calling for integration with social technology movement. Exploring the existing synergies of these counter-hegemonic movements, the dissertation aims to demonstrate that engineers, technologists and other professionals involved with technological development may assume an important role to merge community strengthen and forest conservation. To do so, the methodology developed by Herrera (1981), alluding to the generation and technology for rural areas, is taken as an important reference. The scope of this method is adapted to be applicable to a solidarity economy organization including extractivists of the Lower Madeira River producing and commercializing Brazil nuts. Recognizing the social character of rational systems, the methodology demands qualified participation of the workers and results in the technological space of the organization, agreed upon the associated producers and the professionals aiming to support them. The experience of the adapted method proved to be effective, pointing out that real engagement of specialists with social transformation demands the capacity of dialoguing with groups which and usually considered irrelevant in the technological development process.

The current market of artisanal cachaça has growing continuously in the last years, especially in the last decade. This is a result of governmental programs to stimulate low-scale producers, which correspond to 30% of the cachaça production in Brazil. These familiar producers have been using traditional and rudimentary processes and techniques, with a little or no quality control. The ferment is prepared in an artisanal way (caipira ferment or natural ferment), with autochthonous yeasts and bacteria present in the sugar cane juice. This obviously difficultates the quality control of the beverage, however, it may contribute to a better sensorial quality. The organic cachaça production appears to be a promising alternative for low-scale producers because the demand for natural products, healthy and ecologically correct is increasing. In this context, this work aimed to evaluate the contribution of the type of the ferment (caipira and commercial) and the ageing (in oak barrels) to the chemosensory quality of the cachaça and to the development of this agro-industrial segment. The fermentation with the caipira ferment has shown a great number of wild yeasts and a lower number of total yeasts, however, there was no difference in the number of bacteria comparing to the fermentation with a commercial strain. For the latter, an increased or stabilized number of wild yeasts was observed along the fermentative cycles, white for the caipira ferment this number decreased or stabilized. There was an intense acidification of the medium during the preparation of the caipira ferment, which was repeated in the initial cycles of the fermentation with this ferment, decreasing afterwards. Significant alterations in the composition of redistilled cachaças were observed after ageing in oak barrels, especially concerning to pH, total acidity (fixed and volatile), alcoholic content and secondary compounds, as npropanol, acetaldehyde, isobutanol and total volatile compounds. All the parameters presented values within the limits of Brazilian laws. The type of the ferment influenced the beverage quality, because the cachaça produced with the caipira ferment has shown increased fixed acidity with the ageing, while for the one produced with the commercial strain, there was an increase in the volatile acidity. The sensory tests of preference revealed that the cachaças produced with the caipira ferment were significantly different (p<0.05) from the cachaças produced with the commercial strain regarding the aroma and global impression, after ageing. Although the fermentation with caipira ferment has shown a great number of wild yeasts in the inoculum and in the sugar cane juice, the cachaça produced with this ferment showed better preference. There were no differences in the sensory tests concerning both ferments for the non-aged cachaças, showing that not only the ageing influenced the quality of the cachaça, but also the type of ferment utilized in the fermentation for the cachaça production.

In the context of automated manufacturing systems, combinatorial optimization problems, such as determining the production schedule, have been focused in many studies due to the high degree of complexity to their resolution. Several studies point to use of metaheuristics for the problem dealt, where different approaches perspectives have been proposed in order to find good solutions in a short time. In this paper, we propose an approach based on Ant Colony Optimization metaheuristic (ACO) for the reactive production scheduling problem in an FMS aiming the combination of problem characteristics with metaheuristic characteristics. For this, the problem is addressed from two perspectives, based on modeling and the search method. The problem representation is characterized by a description of the problem at the operations level, since the production schedule is included in this context. On the model is applied a constructive search method based on ACO that using the collaboration principle, establishing a relationship between operations so that it lead the search for promising regions of the solution space. The goal of this work is to obtain a reactive programming in acceptable response time in order to minimize the makespan values. Experimental results showed an improvement of the results obtained so far by other approaches.

Flowering plants need some external pollen vectors to accomplish sexual reproduction. For plants, the access of sexual mates by pollinators agents is a limiting factor, wich make pollen vectors a critical resource for plants to reproduce successfully. Simpatric plants that share the same pollination guild avoid direct competition differing the pollinators use mode. These thesis investigate in a cerrado community the coexistence mechanisms between plant species that use the same pollinators guild, the bats. The work was carried out in a cerrado area in Brazilian southeast, between July, 2007 and June, 2009. First of all, I assessed the chiropterophilous species composition in the area, describe the floral biology and the interactions with their flower visitors. I found nine species framed in the chiropterophily syndrome, and which the flowers received visits mainly from the bat Glossophaga soricina (except in Irlbachia alata). The species flowers are adjusted to the bats morphology, ethology and physiology, and offer flowers all year long, assuring food for the bats. Then I verify the mechanisms that allow the chiropterophilous species coexistence or the facilitative interactions in the area by pollinators share. I assess the floral characteristics, blooming phenology, nectar attributes and floral visitors. Nine plant species share similar floral characteristics that are noted by the bats sense, which play as facilitative interaction between species, which produces a single floral display for attract the pollen vector in common. However, the plant species differ in the places for pollen deposition in the bats body due to differing in floral morphology, species offered distinct nectar volume and concentration which may select/segregate the pollinator and share the pollinator use during the year by flowering at different moments, which allows species that share pollinators to coexist. At last, I checked how two species in the same genus and that use the same bats as pollinators differ in the way to use the same pollen vector. I estimate the bats role in the plants species floral biology and if the species differ in floral characteristics, nectar attributes and secretion time, flowering period. I verified that group - flowers with different size shall avoid pollen mixture among species, nectar with distinct soluble concentration shall attract higher number of visitors in distinct moments, massive flowering in different periods and sequentially, allows the Bauhinia holophylla and B. longifolia coexistence in the area, even sharing the G. soricina use as main pollinator.

A Flexible Manufacturing System is a production system where more than one event can occur simultaneously in parallel, asynchronously or concurrently. These are designed to meet the needs of the market, demand for improved product quality, lower costs and shorter delivery times. Due to the complexity and flexibility of these systems, conflicts can occur when more than one process requests the same resource, such as machines or AGVs, or when a product can be produced in more than one production routing. Thus, a conflict resolution policy is needed in this type of environment. This study uses Fuzzy Coloured Petri Nets for modeling a manufacturing system. The manufacturing system is modeled considering the resources, buffers, production routings, AGV routes and identifying conflict points. The conflict resolution is performed considering both information on the shop floor and production management. Fuzzy rules are constructed to prioritize conflicting processes and a fuzzy rule-based system is modeled on Fuzzy Coloured Petri Nets in the same network as the manufacturing system, making the model of the system independent of other systems of support for the resolution of conflicts. In this work we considered the conflicts that can occur when loading and unloading station and the input and output buffer. According to the source of conflict, a rule base is shaped to assign priorities to processes. From this model it is possible to make the control system and ensure that identified conflicts are resolved.

In the present work, bulk magnesium metallic hydrides (MgH2 and Mg2FeH6) were produced. Commercially pure Mg and mixtures of 2Mg-Fe were processed by severe plastic deformation (SPD) by using High Pressure Torsion (HPT) method, and also by hot extrusion. Studies were accomplished with relationship to the possibility of bulk hydrides production from those materials. Also, it was evaluated the influence of the obtained microstructure from different processing conditions and also the influence of the iron in the hydrogen sorption properties. It was verified that cycles of hydrogenation do not cause bulk disintegration in any samples. The formation of Mg2FeH6 was verified in all samples of the 2Mg-Fe mixtures. This hydride is known by the difficulty of synthesizing. In spite of the excellent results regarding the hydrogenation properties improvement and, in the ability to resist superficial oxidation, a large limitation still exists regarding the use of these results in automotive applications. Bulk hydrides were produced following the conditions studied in this work, however the kinetics is still reasonably slow and the operational temperatures are still high. This fact takes to the consideration of the verification of others possibilities of application types. In the current state of this work, the most probable application is in the static storage of hydrogen, where such problems are not so significant.

The CO preferential oxidation reaction (PROX-CO) has been widely studied in last few years. Aiming H2 purification for proton-exchange membrane cells (PEMFC) use, the main role of the PROX-CO reaction should be reduce the CO contained in reformed gas to an acceptable level of CO concentration that do not provoke deactivation of Pt electrocatalyst. The search for substitutes for noble metals like Pt and Au, the first catalysts tested in PROX reaction, has been the subject of several studies. Among the proposed new solid, the Cu-O-Ce have received considerable attention. These catalysts have been shown be active and selective for PROX-CO in a temperature range that is appropriate for application in PEMFC cells and are materials of low cost. The metal-support interface of Cu-O-Ce system favors the CO oxidation reaction and some properties as metallic dispersion, particle size and morphology are determinants for the better performance of these catalysts. Therefore, in this present work, xCuO/CeO2 and xCuO/CeO2-Al2O3 catalyst (where x is the copper loading) were synthesized, characterized and tested in the CO preferential oxidation reaction. The effects of metal content, support composition, support preparation method and catalysts preparation method were evaluated. Experimental results showed that the metallic content influences the catalytic performance and the catalyst with 1% of copper content was the most active and selective for the PROX-CO. That catalyst also showed the best performance at lower temperature reaction. The study of the effect of support nature in the PROX-CO reaction showed that the strong interaction copper-ceria is a determining factor for the good performance of the catalysts. With alumina or ceria/alumina supports, the metal-support interaction is weaker and, in consequence, the catalysts were less active and selective. The preparation method study of ceria support showed that morphologic characteristics from its synthesis lead to different results of catalytic activity. The catalyst preparation method was important to catalytic activity results. The solids prepared by impregnation and citrate method were more active and selective than others. Although the catalysts synthesized by the deposition-precipitation and co-precipitation methods have also been active for the PROX-CO.

In the contemporary knowledge society, universities are increasingly valued for what they produce and disclose: they earn credibility as they externalize the knowledge produced, making available your content on the web. Much of this knowledge is now registered in digital documents, due to the ease of creation and mainly of access. With an increase in the generation of information in digital format and its rapid technological obsolescence, a new challenge and fundamental requirement arises in this context: digital preservation. Given its importance to libraries university students, the general objective of this research is to develop a computational framework for the digital preservation of scientific knowledge, based on a diagnosis of the technological obsolescence of the Digital Library of Theses and Dissertations of the Community Library of the UNiversidade Federal de São Carlos (BDTD / UFSCar), object of study of the research. Action research was the method used and comprised diagnostic activities of technological obsolescence, based on in a framework of reference requirements necessary for digital preservation, constructed from articles dealing with the theme. After the diagnosis, a computational solution based on free software was developed for the digital preservation of scientific knowledge produced by Graduate Programs Graduation from UFSCar. The results achieved were: 1) formatting and application of a reference structure to support the diagnosis process of the BDTD / UFSCar's technological obsolescence status; 2) development of a computational solution for the digital preservation of scientific knowledge. The reference structure and the computational solution presented contribute to the digital preservation initiatives in university libraries, by making available a system for assessing technological obsolescence and a solution involving the preservation process called Refreshment. The results ensure that the cultural, historical and scientific contribution of the scientific community UFSCar, expressed more and more through manifestations of digital documents, can be continuously accessed, in terms of content and functionality through the technological resources available at the time, having guaranteed its integrity, authenticity and reliability.

Osteoporosis has been considered the most common metabolic disease, affecting about one third of postmenopausal women, accounting for a high rate of morbidity and mortality. This study was to evaluate the effects of a treatment program for aquatic therapy of muscle performance and balance in women with osteoporosis. We selected 40 volunteers, with a densitometric diagnosis of osteoporosis at the beginning and end of treatment, the volunteers underwent a physical therapy evaluation consisting of anamnesis, evaluation of peak torque and work normalized by body mass and power isometric and isokinetic 60 ° / sea 120 ° / s knee and ankle muscles in the dominant (D) and nondominant (ND) with five repetitions, with concentric contractions performed on the isokinetic dynamometer Biodex Multi-Joint System 2. The postural control was assessed by questionnaire Berg, the Time Up and Go test (TUG) and the force platform BERTEC. After the initial assessment, a researcher who was not part of the research generated through computer, a randomization list and placed one by one, in opaque envelopes, which were not translucent sealed. Participants were selected consecutively through the withdrawal of the envelope, and assigned to two groups: control group (CG) and intervention group (IG). The treatment was performed twice a week with one hour for 12 weeks in therapy pool. It is noteworthy that the GC has received the same treatment of the GI, after 12 weeks. Normality was tested using the Shapiro-Wilk test. For comparison of, we used the nonparametric Mann-Whitney test to compare results before and after physical therapy, we used the nonparametric Wilcoxon test. For the evaluation of qualitative data was used chi-square test. It was adopted a significance level of 5% (p ≤ 0.05). In isokinetic knee with a speed of 60 ° / s, there was a significant improvement in the IM variable peak torque normalized by body mass during flexion and extension of member D and ND, the work variable normalized by body mass significant improvement in member D in flexion and in extension of GI, and variable muscle power, no significant improvement in GI and GC. When evaluated the knee joint with a speed of 120 ° / s, significant improvement was observed in all variables of GI and CG no significant improvement and work in variable proportion to body weight not only significant improvement in knee extension of GI ND . In the evaluation of ankle at the speed 60 ° / s, variable work normalized by body mass and muscle power was a significant improvement in all variables of GI. For the evaluation of balance, significant improvement was found for the questionnaire Berg, TUG and some variables of the force platform IM This training program was effective for improving muscle strength in some muscle groups important for maintaining the standing posture and activities of everyday life, thus reducing the risk of falls.

With the advancement of hardware capability and key technologies of software and networking, ubiquitous computing is becoming a reality. The term ubiquitous computing refers to environments saturated with computing devices and communication networks that integrate naturally to human activity. According to Mark Weiser, the father of ubiquitous computing, "the most profound technologies are those that disappear." In this sense, ubiquitous computing can be considered the opposite of virtual reality. While the second one the user enters the virtual world, the first computing is penetrating into the user's physical world, building the connection between the two worlds. Research in different areas have been undertaken to improve the process of software development in ubiquitous computing. In software engineering, this new paradigm, mainly due to the amount and diversity of devices and platforms, present problems, such as applications development in manual and on-demand, and difficulties in maintenance and development of applications to meet the new requirements and monitor changes platforms. These problems have motivated the search for methods, processes, techniques and tools for modeling, implementing, testing to support the development of ubiquitous applications. Motivated to search for a solution to these problems, this project developed a model-driven approach to building software in ubiquitous computing. The approach is based on Domain-Specific Modeling (DSM) and Model-Driven Architecture (MDA). With a focus on reuse of software at different levels in the life cycle of software from the application modeling through implementation, the approach provides a productivity gain in application development that must be performed on different architectures of ubiquitous computing, as the numerous mobile devices such as cellphones, PDAs and others. The main mechanisms that automate part of the activities of a Software Engineer in implementing the approach are: a CASE tool, a code generator for the modeling of specific applications of a field, the IDE (Integrated Development Environment) Eclipse is a framework for science context and content adaption. Case studies in the field of medical education were developed to test and evaluate the proposed approach.

The decision support tools are importants in many domains of our society. But there is a need to make users understand the decisions made by those tools in order to increase the faith of the users on the results. In the literature, Bayesian networks are considered as a probabilistic classification system with good performance. But it still need a better presentation of it results to make it more understandable to the users. In other hand, the fuzzy logic ofer potential to deal with imprecision and uncertainty, as well as a linguistic representation, which facilitates user's understanding. The combination of Bayesian networks and fuzzy logic is proposed by the method BayesFuzzy, which make use of fuzzy rules as a form of explanation of a Bayesian network, it aims to obtain a decision support tool with good performance and easy to be understood by users. So we are proposiing the method Pruned BayesFuzzy (PBF), it is a BayesFuzzy incorporated with minimum certainty degree, default rule and Rule Post-Pruning as a form to select the most important rules for classification between all the rules generated, it also simplifies those rules. The results of PBF show an improvement in understanding but a loss in correct classification rate. But the improvement in understanding is promising enough to further research and enhance of the PBF. Then beside PBF, we also propose the Pruned BayesFuzzy 2 (PBF2), which is PBF incorporated with a feature selection technique based on Markov Blanket. With the incorporation of this technique, it's possible to deal with situations that contains a large amount of variables inside of the Markov Blanket of the class variable. The results show a loss in correct classification rate, that is already expected when we try to simplify further more the Markov Blanket. However, the availability to be able to deal with big scale problems is something to be considered.

This paper proposes a case study in a computer room at a school for Special Education of a midsize city in the State of Sao Paulo, with a teacher of this modality of teaching. The objective was to develop computerized teaching strategies which foster the learning of children with disabilities in special classes through the process of training teachers for this purpose. As a research problem arose the question: How to transform the teaching of a computer room dedicated to serving people with disabilities? To identify the practices of the teacher in the computer room before the stage of intervention was developed and implemented an initial questionnaire, immediately after the intervention was administered a questionnaire to determine the final outcomes after this step. Data collection for the entire intervention process was described in a diary, which was completed in the ending of each stage of intervention. The digital literacy of the teacher was important for the new feature available in the school favored the formation of its students with a teaching practice consistent with current reality. However the computer room was only used when the researcher was present at the school. For the teacher the research contributed to her teaching practice because she did not know before how to use the computer resources as a teaching resource. Other relevant data is the scarcity of time and lack of organization of school hours for use of the school environment.
