The filtration of gases is an important industrial operation with the primary aim of removing unwanted solid particles contained in a gas. The filtration of gases at high pressures is an operation widely used in natural gas industry with the aim of separating impurities called black powder, from rust inside pipelines along the transportation. These residues can cause wear on equipment such as, for example, rotor pump, obstruction of gauges and pressure decrease in product quality. Despite being an operation widely used, few studies exist in the area to study what the best type of filter. Therefore this study is very useful to improve the steps of transportation, measurement and purity of the final product. To simulate this process, we used the dry compressed air, injecting a phosphate rock as particulate matter. The filters were tested RAD cellulose and acrylic. The surface speed of filtration was kept constant at 0.05 m / s, throughout the filtering operation. The flow of compressed air used were 14 l / min to the total pressure 1 bar, 42 l / min at a total pressure of 3 bar and 86 l / min at a total pressure of 6 bar. Total load losses were 5, 10, 20 and 30 mbar. The results showed that, initially, the curves of head loss versus deposited mass showed the same growth trend. However, when forming a layer of cake from about 0.03 kg/m2, the filtrations higher pressures had lower pressure loss. This is because the larger pressure forming pies more porous and less resistant to air flow. At the end of the study it was also observed that the acrylic filter performed better compared to the cellulose RAD, due to its greater mass of accumulated dust and low pressure drop.

The objective of this work was the development and application of a Virtual Learning Environment (VLE), based on the Moodle platform, for the study of Mathematic topics at the elementary education level. Furthermore, another purpose is to observe the student's work within this environment and, subsequently, the analysis of the results of this proposed teaching method. The VLE concept was developed with the ISMART foundation students in mind, which are studying at the Bandeirantes School, in Sao Paulo. This foundation is a nonprofit organization that grants scholarships to academically well performing students as well as those of low income families, which are selected through exams and interviews. The selected themes within VLE are quantities and also measurements, chosen for their importance and relevance in every-day life, divided into four units: Measurements of Length, Surface, Volume and Percentage. Emphasis is given to the concept of measurement, by studying the various quantities and diverse approaches, such as: historic, the use of nontraditional unit standards and interactive applications. In relation to the percentage theme, it is important that the students familiarize themselves with different representation of rational numbers (fraction, decimal and percentage). Besides that, this theme is part of the everyday information, where we are dealing with spreadsheets, graphics and statistic data. As part of the VLE, it was the intention of this study to seek real life problems that would involve the use of calculators for more complicated calculations. Furthermore, mental percentage calculations were practiced by applying a specially developed game. Resources were utilized in form of texts, images, audio, video, flash animations and Geogebra applications, besides PowerPoint exercises that were solved in a step by step method as well as other proposed exercises. The VLE was executed with ISMART students of 2011 and 2012, whereby some activities were developed at the School and others at home.

The interaction between humans and the computers has improved substantially during time through the evolution of interfaces of interaction. The possibility of users to interact with machines through several modalities of communication, and in a natural way, can increase the level of interest from the user and ensure the success of the application. However, the literature of the area of multimodality has shown that developing such interfaces is not a simple task, mainly for non-experienced or recently graduated professionals, since each designer’s modality of interaction has its complexity in technical terms, as acquisition and adaptation with new tools, languages, possible actions and etc. Moreover it is necessary to verify which modalities (voice, touch and gestures) can be used in the application, how to combine these modalities in a way that the stronger point of one completes the weak point of the other and vice versa, and also knowing in what context the final user will be involved. The GuiBuilder Multimodal was developed aiming to try providing the basic needs in implementing an interface that uses voice, touch and gesture. The framework promotes an interface development through the WYSIWYG (What You See Is What You Get) model, where the designer just sets some parameters so the component is multimodal. During the interface creation phase, agents supervise what the designer does and supply support, clues, with design patterns that might be divided in categories such as: multimodality, interaction with the user and components.

The aim of this study was to use experimental design techniques during the development and validation of high performance liquid chromatography (HPLC) methods for analysis of drugs in the pharmaceutical industry in order to demonstrate its applicability and benefits of its use. A multivariate assessment of the robustness of an assay method for vitamins of the B complex enabled the visualization of interactions between variables, which would not be possible through the univariate approach. A mixture design was performed for determining the extraction solvents of sesquiterpene lactones in pharmaceutical formulation containing arnica tincture. The mixture of solvents selected through the study allowed desirable extraction of compounds of interest from the sample, which was confirmed through the validation of the methodology. Finally, we conducted an exploratory planning on an analytical methodology for the determination of latanoprost, timolol maleate, preservatives and degradation product in eye drops. The design allowed the reduction of chromatographic run time and waste generation by about 44%.

To increase the awareness of breastfeeding practices, one must bear in mind that this is a complex act, permeated by the influence of several factors, including the family members. In order to better understand the family context of pregnant/lactating women and identify what they learn with their mothers and mothers-in-law we developed the following research question: What are the existing educational processes in the dialogue between two generations of women about breastfeeding practices and newborn care practices? The objective of this study was to understand what women of different generations learn and teach about breastfeeding practices and newborn care practices, seeking to reveal the type of support and influence that mothers and mothers-in-law may exert on breastfeeding practices. This was a qualitative study, which had the participation of eight women residing in a low socioeconomic neighborhood, and the following techniques were used for data collection: semi-structured interviews and informal conversations. For data analysis we adopted the assumptions of the hermeneutic-dialectic analysis, which led to the development of categories that enabled us to understand: the diversity of motherhood and breastfeeding experiences, the grandmothers knowledge on breastfeeding, the educational processes in the dialogue between women of different generations and the grandmothers potential for encouraging and supporting breastfeeding. We conclude that grandmothers are reference persons in the family, that they have various forms of knowledge about breastfeeding and about caring for newborn babies and who transmit this knowledge to their daughters and daughters-in-law. Thus, when developing actions to promote, protect and support breastfeeding, health professionals need to acknowledge and value the knowledge that women bring from their own child rearing experiences, in addition to building a dialogical relationship that enables to consider and expand this knowledge, enhancing the role of grandmothers as supporters of breastfeeding.

The aim of this dissertation is to present how homeless people have been produced and managed in a contemporary context. It also intends to show how changes in the practices of care to the homeless influence directly in their daily lives, specifically in the ways they organize themselves in the city. We highlight bancas - a term which defines, in Carlos and in other cities of São Paulo s State, groups of homeless people which are designed in certain places of the city. We have chosen the bancas as the locus of analysis here due to the fact that it is the most common way of living on the streets among the homeless in the researched city. Also, it gives a visibility to these groups in the urban space, obligating the creation of new forms of public management to this situation. As a mythological approach, we developed an ehtnograpy on Social Care Institutions and on the streets. Also, we performed in-depth interviews with care workers. The use of ethnography allowed us to develop analytical constructs such as Circulation and Settlement , which permitted us to conduct investigations about the changes in care practices in this population, giving the contemporary device of public management on the issue of the homeless.

This research aimed to conduct a few works that articulated the category race to the field of education in order to verify the relevance of the role played by the school institution as it relates to ethnic-racial issue in Brazil. Seeking to achieve this objective it is a mapping of the papers presented at two major national associations of research and graduate of Social Sciences and Education, the National Association of Graduate Studies and Research in Social Sciences (ANPOCS) and the National Association of Graduate Studies and Research in Education (ANPEd) during 1988-2003. The observation of the aforementioned mapping identified the concepts of identity and citizenship presented directly related to ethnic and racial issues and education in the analyzed texts. Both this mapping as the monitoring of the contemporary literature of Social Sciences and Education, issues related to ethnicity, race, reported the need to study the relationships established between the formal education, the black movement and educational policies. In this sense, the research aimed to examine the interconnections between theoretical treatises that articulate race and education in ANPOCS ANPEd and pointing to the understanding of space and school education as central places in the constitution and re-discussion of the parameters of citizenship and / or as construction place processes to identify the persons to whom they are intended educational processes through the racial-ethnic membership. Finally, we sought a rapprochement between the normative instruments / legal policies that institutionalize public education in the country: the Law of Guidelines and Bases of Education (LDB), the National Education Plan (NEP) and the Development Plan for Education (PDE) and discussions presented by the works analyzed.

The Amazon region has the largest hydrographic basin on the planet, the one that includes Amazon River, and it also has the largest rainforest in the world. Moreover, it presents a great biological diversity, both related to the fauna and flora, and microbiological. Microorganisms are responsible for most biogeochemical cycles that shape the terrestrial environment and the freshwater and marine ecosystems, and they can be widely exploited biotechnologically. It is estimated that less than 1% of all bacterial species is known due to our inability to simulate the environment in which they live. However, new techniques have allowed the study of these microorganisms. Through Metagenomics it is possible to study complex environmental samples without the need for isolation and individual cultivation of these organisms. For this purpose, the16S ribosomal DNA (16S rDNA) is used in bacteria and archaea in order to study phylogeny and diversity. This sequence is used because it has been fairly maintained during the processes of biological evolution and it may serve as an indicator of how organisms are closely related. For these studies, this region was amplified by the Polymerase Chain Reaction (PCR) and cloned into vectors through the recombinant DNA technology, thus enabling the construction of 16S rRNA libraries. These libraries were then sequenced and the microorganisms were identified by comparison with databases. In this study it was used DNA extracted from Solimões River filtered water, in addition to water from other rivers and adjacent lakes, to the construction of libraries, in order to study the biodiversity through 16S rRNA analysis. In all libraries, phylum Proteobacteria was the most abundant, and most of the genera observed belong to the Betaproteobacteria class. The freshwater cosmopolitan taxa Candidatus Planktophila limnetica and Polynucleobacter were observed, as well as primary producers were represented by the genera Synechococcus and Cyanobium. Samples in which the construction of 16S rRNA libraries was possible for Archaea, the phylum Crenarchaeota was the most abundant in all libraries.

This paper discusses the use of Information and Communication Technologies (ICT) in Chemistry Technological and Investigative Gymkhana, activity of the Sciences Center of Araraquara, an UNESP science museum. The objectives of this study were to investigate the use of these resources in the activity, the conception of these participants on such use and contributions to the Teaching of Chemistry. The research subjects were museum visitors students and data collection was done through a questionnaire answered at the end of the visits. The data indicated the participation of students from public, private and SESI system during the period of analysis. It was observed that the computer is materialized as a cultural tool and is used by visitors during GTIQ to perform the action for resolution of the proposed activity. Also making use of the internet to search for information, visitors indicated appropriate of this resource as a mediator of the action. So we can suggest that the use of technological resources changes the relationship of the students with the chemical contents, since they showed more interested when using equipment to which they have affinity (cellular and computers). Another important factor to be noted is that the use of ICT makes the search for information more dynamic, which, in the view of visitors, facilitated research and become more motivating. ICTs used during GTIQ played motivational role, arousing the interest of visitors by subjects and drawing attention to the same themes. ICTs being used in a investigative approach encouraged the active participation of visitors. Technological resources used during the activities of the Gymkhana had their potential exploited, helping assisting visitors in the problems solving presented and stimulating the use of the Internet as a learning environment.

Photodynamic Therapy (PDT) is known to be limited to applications in large volume tumours due to its limited penetration. Therefore, the PDT with the Luzitin® photossensitizer as well as a combination of PDT and laser surgery may constitute a potential to destroy bulk tumors. Thus, with the aim of proposing a minimally invasive treatment protocol involving the application of PDT for large tumors, the present study analyzed histomorphometrically necrosis resulting from both a combination of a laser ablation with PDT as PDT with the photosensitizer Luzitin® (a bacteriochloryn synthetic with greater potential for penetration into biological tissue) in livers of healthy rats. In the first study, 87 animals were divided into 2 groups: CO2 laser and diode laser. Each of these groups were subdivided into six subgroups: 1) only laser ablation, 2) administered the PS and ablated with laser, 3) only PDT (drug and ligth), 4) drug and light (PDT) followed by laser ablation, 5) ) laser ablation followed by a PDT and 6) drug, followed by laser ablation and ligth. For each subgroup, three types of photosensitization were used: topical 5- aminilevunic acid (ALA), intravenous ALA and intravenous Photogem®. Thirty hours after the different treatments, the animals were sacrificed and the livers removed for the histological and morphometric study of necrosis. The results showed that the effects of treatment were considerably improved when PDT was used in combination with laser ablation. For the group CO2 laser, the average depth of necrosis obtained showed a minimum difference between the studied conditions for the group photosensitized Photogem® and with an increased depth of necrosis after the combined procedures in comparison with the isolated techniques for the subgroups fotossensibilizados with ALA, especially treatment with PDT was performed before ablation by CO2 laser. In the diode laser group, subgroups with better performance were those in which the ablation was performed before PDT using intravenous photosensitizers and ALA topic. From these results, it is suggested that PDT and laser ablation can synergistically in the treatment of large tumors. In the second study, sixteen normal male rats were randomly divided into 4 groups with 4 animals each. Initially, all groups were intravenously photosensitizated with 2 mg/kg or 2.6 mg/kg of the drug and after 12 hours, a 1cm2 of area, in the right abdominal region, corresponding to the liver, was irradiated during 22 minutes and 13 seconds or16 minutes and 40 seconds. Groups are described following: 1) control group: photosensitized with 2mg/kg, but untreated, 2) treated group 1: irradiated with light dose of 100J/cm2 after photosensitization with 2mg/kg of 12hs and 3) treated group 2: irradiated with light dose of 70J/cm2 and photosensitized with 2mg/kg of Luzitin®, 4) treated group 3: photosensitized with 2.6 mg/kg of the drug and irradiated with light dose of 70J/cm2 Animals were sacrificed 30 hours after irradiation, except the control group, which were sacrificed 42hs after drug administration. Livers were removed and prepared for histological analysis. Moreover, macroscopic aspects of liver were observed. Results showed significantly more extensive necrosis and greater severity in treated group 1. Data suggested that, among the conditions studied, light dose suitable for PDT treatment of photosensitized tissue by Luzitin® is 100J/cm2 and that 30% of reduction in this value produces decay in PDT response, even with proportional increase of drug concentration in the organism.

In recent years the possibility of incorporating the process of Learning Organizational (LO) during the life cycle of projects has been drawing the attention of scholars. However, there are few studies that analyze the subject in a practical and deeper way. The traditional studies try to consider and discuss the learning after the project more accurately due to its wide use in the business world. Nevertheless, the learning process may also occur during the projects when stimulated by mechanisms that systematize the externalization of knowledge and by means that encourage the sharing and the transference of them between projects team. Structured by means of a research action, this dissertation collaborate with the expansion of the knowledge about the subject investigating and improving actions that promote the practice of learning organizational during the development of projects in a medium-sized Consulting Engineering company from the civil construction sector located in the metropolitan region of São Paulo. The actions are guided aiming to promote the transference of explicit knowledge (technical documents and reports), the reuse of the learning from their own experiences and past history (tacit knowledge) and the systematic problem solving. The implemented actions were incorporated in the procedures of the Quality Management System of the Company and, from trainings, observations and informal and formal evaluations (internal and external audits) it was possible to point opportunities of improvements to reinforce the process of organizational learning during the development of projects. The research revealed that the transference of knowledge generated in documents, reports and technical studies to other projects is not effective in organizational level, being a lot more employed among the project coordinators with more length of service that know a larger number of projects performed or ongoing. In the other hand, despite the tacit experiences developed by the people (own experiences), the learning occurs when the coordinator of a project compulsorily identifies and registers in a Project Execution Plan (PEP) the similar developed or developing contracts in the company, interrelating them with the people involved in these contracts. Following the process, the plan is disclosed to the team members of this coordinator, which consult those people. The generation of knowledge provided by the dynamic of systematic problem solving appears as incipient because, in the consulting engineering, a lot of factors hinder the capture of this knowledge in the form of register for later reuse. Among these factors it is possible to mention: difficulty in determining the categories of problems that comprehend all the projects, imposition of the clients not to generate registers, hesitancy of the project coordinators to externalize the problems of the projects and, as a result, their reputations.

The use of pesticides in agriculture, in order to enhance and ensure food production for a growing population has led to many concerns about risks to human health and the environment. Therefore, search for new strategies which seek a safer alternative is very important. With this aim, herein we describe new ruthenium(II) and magnesium(II) complexes containing phenanthroline and flavonoids (hesperidin, hesperetin, naringin or naringenin) ligand, These complexes were synthesized and characterized by elemental analysis (C,H,N), atomic absorption and ESI-MS(+). The structures were investigated by computational calculation and 1H, 13C NMR spectroscopic techniques. The complexes are stable in solid state, in most of the organic solvents tested and at various pH values. They are more hydrosoluble and liposoluble than the free flavonoides. The insecticidal activity bioassay against the leafcutting ants Atta sexdens rubropilosa demonstrated that the complexes show a delayed kill action. The activity of the Electrophorus electricus AChE enzyme was moderately inhibited by the Ru2+ complexes whereas the Mg2+ complexes were powerfull inhibitors only against AChE of Atta sexdens rubropilosa, indicating their high selectivity to insects. Further, the complexes are essentially non-toxic to the aquatic bacterium Vibrio fischeri and to human HeLa cells. The Mg2+ complexes presented unique properties: (i) in the electrochemical experiments in aqueous solution was observed the formation of a cyclic mechanism stable involving neutral, ionic and radical species; (ii) are better scavenger superoxide radical than the free flavonóides; (iii) presents a strong blue fluorescence. They act as an on/off fluorescent switch through the changing of the medium, solvents and pH. The fluorescence observed by confocal microscopy allowed to detect the high absorption of the magnesium complexes in the HeLa cells. Overall, the physicochemical and biological properties observed for Ru2+ and Mg2+ complexes opens new frontiers of application for these compounds in various areas of science such as agriculture, medicine, and optical materials.

The Internet suffer an increased amount of traffic. This increase could affect the structure of computer networks generating packet losses and delays. This loss and delay stems from the packet flows that generate more traffic that particular path or subpath, can support. Given this situation we show in this paper a mechanism based on P2P that balances the load by using multiple paths along with the breaking of the flow in smaller streams. For this mechanism called P2P-Flow that can be implemented in OpenFlow. In our simulation we compare this mechanism with multicast and unicast in multiple scenarios. The contributions of this work are detailed in the idea P2PFlow and compared with the multicast and unicast topology in various scenarios.

Postural stability is an important ability of the human body in standing position as well as in dynamic activities like locomotion. It influences all motor and muscle aspects related to the execution of a motor task and is achieved by appropriate support conditions, coordinated muscle activity and proprioceptive information. The center of pressure behavior can be studied under different conditions, providing information on how the body reacts to postural instabilities. Thus the main purpose of this study is to propose a methodology for the study of the center of pressure behavior in order to evaluate static and dynamic equilibrium conditions of the human body. In order to achieve the goals, the structure of this thesis is composed of three studies. The equilibrium control during single leg ballet poses and the anticipatory postural adjustments prior to the first step in gait were discussed in the first and second study respectively. In the third study, methodological aspects were reviewed and a data processing standardization to study the center of pressure behavior during gait initiation was proposed. Dynamometry with force platforms was the measurement method used for all studies. The results allow to identify balance control strategies in ballet dancers and anticipatory postural adjustments existing during the transition from standing still to the cyclic gait steps. Some clinical applications of the results are presented and also directions for future studies.

Autonomous mobile robots are machines capable of executing repetitive/dangerous tasks more efficiently. Most of them have an embedded software which is responsible for their execution. Over the last years, the complexity of these applications has continuously growing and they are presenting challenges that are uncommon to traditional information systems development. Therefore, any technique that can support their development is a great contribution. A technique that improves the productivity is to use domain-specific languages (DSLs). These are modeling and programming languages whose constructs are concepts and abstractions of a particular domain. It frees developers from worrying about generic programming concepts (classes, objects, attributes, etc.) and allows them to focus on the problem to be solved. As creating a DSL is not a trivial task and pointing the idiosyncrasies of mobile robots, this dissertation presents an approach for engineering DSLs to mobile robots. The aim is to make the activity of creating DSLs to this domain more systematic and controlled. In this approach, an application is taken as input and a series of domain statements is extracted from it. These statements are classified into categories and each one of them are analized in order to extract commonalities and variabilities, wich are transformed into components of a DSL. An important characteristic of the approach is that it asks for just one application to reach a first version of a running DSL. We suggest that the same DSL can be evolved just by applying the approach again using another application as input. So new components could be created and the existing ones could be modified. We also present a generic language model providing a foundation architecture that allows one to easily create new DSLs by extending it. Two proofs of concept are presented in order to exemplify the application of our approach.

Software development techniques continually evolve in order to improve development and maintenance processes in addition to lower costs and higher quality. The goal of MDD is to reduce the semantic distance between a problem and its solution specification. Therefore MDD focuses on high-level abstraction modeling and successive model transformations, until finally, generate code. Studies assert that model-driven development can be significantly more efficient than traditional source code-driven software development and still reduce the possibility of occurrence of several problems during the software life-cycle. Likewise, Web engineering can also be benefited by MDD adoption, especially when supported by approaches that facilitate MDD use. Web development is usually agile with frequent releases, these approaches must be flexible to adapt to this context. However, generally, the approaches proposed by the academic community have complex processes which involve many different model definitions, programming languages, plug-ins and IDEs. These features contradict the practices adopted by Web developers. This paper presents the MWDA (Model-Driven Web Applications) approach that provides a simple process to support model-driven web development. This approach does not depend on tools, technologies or plug-ins and encourage combination with other forms of reuse and development processes. Furthermore, the Ruby- MDWA was developed with Ruby language and Ruby on Rails framework support, in order to create Web applications with MDWA assistance. This tool provides a set of textual models and defines M2M and M2C transformation tools, maintaining the requirements traceability since its specification to its construction and further maintenance. In order to show the use of the approach and tool, it was performed a real study case with a software company, from São Carlos SP, where a project management system was developed. In parallel, two experiments were conducted with undergraduate students in Computer Science and Computer Engineering and a Masters in Computer Science, to evaluate the gains and limitations of the Ruby-MDWA tool.

The sources selected were the theses defended in Physical Education Graduate Programs in Education at UFG, PUC / GO, UNB, UFMT, UCDB and UFMS and the Graduate Program in Physical Education at UCB / DF and UNB from the beginning of creation of these courses by 2010. For the development of the collection were developed two forms with the help of MS Excel work sheet named: 1 Form Collection Bibliometric/Epistemologyand2 -Form for Collection of References. The first form was composed of bibliometric indicators (author, year, coach handbag, concentration area, online search, job title, institution, graduate program, keywords, abstract, etc.) and elements underlying epistemological analysis, which were adapted and included building on the instrumental analysis called "Mother epistemology." The results showed that there was a predominance of bias biological and biodynamic(from the empirical-analytic approach38%) in the production of scientific EF produced mainly in PPGEF However, apart from these, there are in evidence and booming scientific production is more critical for consolidation in this region of the country, demonstrated by their characteristics and interests from research conducted in Education Programs, as well as the evidence revealed in PPGEF the UNB/DF greater scope for the construction of other references (phenomenology and Marxist which to gether accounted for59%), strengthening and rescuing the subarea sociocultural and pedagogical.

The advance of pedagogical thinking supposes beforehand a more intelligible elucidation of the relationship between work and education. In the current sociability, despite the hegemony of industrialism and machinery, the craftsmanship of the past still remains in different ways and plays an important role in the formation of education. Thus, the role played by craftsmanship in Education is the main subject under investigation in this thesis. Also, the general goal is to investigate the purpose, content and form of craftsmanship in contrast with industrial work in order to criticize the aims of the former set by the studies on Education. The main idea is that the precedence of craftsmanship in pedagogical thinking hinders and delays the social function of school education as well as the integral development of generations. This study carried out a literature research that combined the method of investigation with the method of exposition by presenting results intrinsically linked to the corpus. The theoretical perspective is based on the Marxist tradition, in special on the studies conducted by Karl Marx and Antonio Gramsci. The thesis was organized into three chapters: (1) "Craftsmanship in the 'shadows' of industrial work"; (2) "The heritage of craftsmanship in contemporary Education"; and (3) "Challenges for the contemporary pedagogical thinking". The conclusion remits to the identification of three problems: (1) the contradictory aspects of craftsmanship; (2) the allurement of the pedagogical principle based on experience; and (3) the mismatch between the pedagogical principles based on work and experience. Four fundamentals were established following the problems which were pointed out in the conclusion: (1) the great theme of contemporary pedagogy is the relationship between work and education; (2) craftsmanship holds precedence in the contemporary pedagogical thinking; (3) the cursed legacy of craftsmanship jeopardizes the universalist character of pedagogical thinking, risking the social function of school education and the integral development of generations; and (4) as the current pedagogical studies can be understood as an affirmative proposal for human formation and school education and as a mediator between mankind and cultural work, their challenge is to detect the contradictions resulting from this ideological operation and suggest new ways to overcome them. It is also said that work - vital activity and pedagogical principle is an open book for the objectivation of mankind s generic life and for the school education in which the contemporary of our time is formed.

This research aimed at salvaging the history of creation of three school institutions from Minas Gerais State (Brazil), as far as history, capitalism and education are concerned, focusing on the Professional Education, mainly for the Agricultural Teaching: Uberlândia Campus, belonging to the Federal Institute of Education, Science and Technology of Triângulo Mineiro (previously named Uberlândia Agricultural School and Federal Agrotechnical School of Uberlândia) and Rio Pomba Campus (previously named Rio Pomba Agricultural School, Agricultural Gymnasium of Rio Pomba and Federal Center of Technological Education of Rio Pomba) and the one of Barbacena (once named Barbacena Agricultural school, Agricultural School of Barbacena and Agrotechnical Federal School of Barbacena), which belong to the Federal Institute of Education, Science and Technology of the Southest of Minas Gerais. Its objectives were the following: a) understand what motivated the creation of these institutions in the countryside of Minas Gerais State, in terms of education policies and its relations to the national economy aimed at the agricultural sector; b) understand if the pedagogical practices of the Agricultural School were in accordance with the desired aim , considering its foundation, and if they were in consonance with the laws; c) investigate if the formation of the Agricultural or Farming Technician, offered by these institutions, has been in accordance with the Agricultural modernization during the researched period and if this formation was accomplished in and to this modernization desired by the Federal Government; d) analyze its curricular structures and verify if they were all identical; e) evaluate which social class it was aimed at. In order to carry out this investigation, a sinuous methodological way was used to comprehend a bibliographic review of the most adequate themes to the research and the analysis of oral, iconographic and written sources. As theoretical support, we can highlight the contributions of Magalhães (2004), Faria Filho (2003), Werle (2004), Fonseca (1961a; 1961b), Cunha (1979a; 1979b; 1983; 1984; 2000a; 2000b; 2000c; 2001), Ianni (1996), Prado Júnior (1967), Ramos (1995), Romanelli (1998), which are already considered acknowledged studies by the Brazilian traditional, technical and professional education, mainly, in the context of its public policies and the critical appreciation of the composition of this chain of institutions in the national scenario. In their historic trajectory, the searched schools experienced a series of transformations which, in the superficiality of the legal texts, were conducted for administrative reasons, but which, under a hermeneutic point of view, were deliberated transformations to meet economic issues. The acknowledgement that the economy and the political interests determined the routes of Education in Brazil, becomes even more obvious when, in the modernization context, the School-Farm System was implanted, according to which pedagogical practice and the production in economical conditions are confused and direct the formation of the technician to act as an agent of modernization. The used sources (public and institutional archives, local newspapers, Town-hall minutes, pictures, bibliographical mapping, etc) enabled the analyzes and the comprehension of the facts and educational discussions in national and regional levels and permitted to confront them with those described by the specialized literature to the Brazilian reality. Finally, the thesis establishes a dialog with historic and theoretical bases and also search for interrelations with Brazilian Education issues, mainly, the ones which refer to Agricultural teaching.

Assuming that the work is the central category in the production process, the relationship between the recent modernization, in special in the harvesting activities, and the manual harvesting work intensification were studied in the Sugarcane Agroindustrial Complex of São Paulo State. The work intensification, which involves high energy expenditure by the workers, is produced by a strong degradation of their life and work quality, in special as a result of the meritocracy system adopted for their payment, once it takes into account the sugar cane harvesting production per worker. The modernization of the Brazilian agriculture, that started in the 60`s, heavily influenced the manual work intensification. At that time, the Brazilian organization model encouraged an aggressive concentration of land and capital, and tried to suppress most of the social workers movements in rural areas. In the 90 s, the sugar and alcohol sectors presented a sharp increase, mainly due to the broad plan for implementing the use of biofuels, specially produced from sugarcane. A new process of modernization started in 2007, when an agri-environment protocol was signed up between sugar cane mills owners and the State of Sao Paulo government. Seeking to reduce the environmental and social liabilities of this sector, this protocol prescribes the end, by 2014, of the pre-harvesting sugarcane burning in areas where harvesting could be mechanized. The present study includes information from three sugarcane mills and from interviews with actors of the Agroindustrial Sugarcane Complex of São Paulo State to evaluate the consequences of sugarcane harvesting mechanization on manual harvesting labor intensification. Taking into account the harvesting costs, it was obtained a value of R$6.24/ton by using manual harvesting and R$3.41/ton to R$5.33/ton when harvesting was mechanized, taking into account 860 and 550 ton/day of harvested sugarcane. ..These results indicate a great economic advantage of the mechanized over the manual harvesting. Therefore, it was observed that mechanization did not attain the goals proposed by the agri-environment protocol. The sugarcane manual harvesting is still widely used to support the mechanization harvesting , which include areas of high slope and low machine accessability. Higher productivity areas are mechanized to obtain higher benefit/cost, leaving those of low productivity for manual harvesting. The comparison of the historical series data of the manual harvesting productivity between 2007/2008 and 2011/2012 indicates that sugarcane harvesting mechanization is responsible for the increase of labor work intensification, This increase in work intensification 10 is a consequence of the effort to attain about the same wage as before harvesting mechanization was implemented.
