Diálogos e aprendizagens na formação em agronomia para assentados

This thesis aims to investigate the Agronomy course in the perspective of the graduation course for the settlers of the Universidade Federal do Pará- Marabá. This course requires a partnership with the social movements of the North region of the country, with the purpose to understand knowledge production and how learning process occurs from the point of interaction and reliable relationships which are established in the organization during the course. The base of theses studies is to reflect of how the dialogue and learning processes occurred during the Agronomy course and resulted in changing in the teachers behavior and in the other integrated members of the group and mainly in the graduating settlers students. These changings happens as a consenquence of the dialogue production between the most varied areas, different people and institutions which take collective decisions. I observe educational actions, researches, extention concepts of extension and also development researches presented in the educative actions discussed by Freire (1985), Simões (2001, 2003) e de Amartya Sen (2000). The theory in which I am basing these studies are based in Boaventura de Souza Santos Simões (2001, 2003) and Amartya Sen (2000). Methodologically I analyse knowledge production by sudying the thesis and scientific works related to rural education, social movements, university and higher education in the last 20 years. I analyze the scientific works of all settler students, and besides, I do open interviews with the students, as well as, with the teachers and the leaders of social movements (MST, FETAGRI, CPT, EFA/FATA). I organize and analyze all the speeches from the ecological knowledge as defined by Boaventura de Souza Santos (2006). Finally, I visit five towns of municipal districts of the southeast of Pará, which represents the final methodological part of the research, in order to verify in loco the practices of the experiments purposed as final activity of the Agronomy course. I organize the work in five areas composed by the occupational process and the initiatives which emerged from them; development model and the social and environmental consequences; I also organize the university role and the relationship established between people and institutions which gave origin to the Agronomy course of UFPA and the programs developed in the region; conjuncture of creation of the groups of settled students, curriculum, principles and focus on the course and the experienced actions; developed practices in the course and the relations of reliability experienced internally and externally to the Academy, the learning and dialogue promoted by the course. I believe that the dialogue has caused changes in the organization of the knowledge and in the educative practices of the teachers, as well as, in the socio-productive practices of the regressed settled students

Simetria na dança: vestígios matemáticos na prática da dança esportiva em cadeira de rodas

To investigate in practice of the Wheelchair Dancesport (WDS), the mathematics of the characteristic isometric movements of the dance of ChaChaCha was the generating subject of this study. The subjects and the locus of the research were the athletes dancers of the Associação Baiana de Dança em Cadeira de Rodas (ABDCR). Referred him study aimed at to describe reflections concerning the athletes' practicing dancers of the technical acting Wheelchair Dancesport, using the inherent mathematical knowledge to the isometric movements executed in the ChaChaCha. For that, I stimulated in the athlete dancer the need to be investigating of his/her own practice, motivating him/it to be searching of information that they collaborate with his/her technical refinement, proposing like this roads to make possible his/her growth, while dancer and, also, promoting of their own movements. To reach my objectives I dialogued with some specialists to understand, to the light of their theories as, Espaçonumerática, Sociology of the mathematics, Etnomathematical, Dance and Symmetry, as those spaces they interact with the atmosphere of the Wheelchair Dancesport and that contributions could supply to the study. However, two authors of the Dancesport for walking , Ried e Laird, they brought contributions that aided in the creation of a prototype for the study of isometric movements in practice of the modality promoting the interface between the theory and the practice. The study showed to be possible to navigate still with the Mathematical Education in an universe little known as the one of the Wheelchair Dancesport. And it is in this adapts that propose a more attentive glance to the illustrations executed by the athlete dancer wheelchair and walking , in the dance of the ChaChaCha, verifying and proposing an analysis with focus investigate, looking for mathematical tracks concerning the symmetry that you/they characterize some of their illustrations

A recepção da criança com deficiência intelectual ao texto literário na educação infantil

The focus of this thesis is children's reception to literary texts starting from literary livelihood in an inclusive literary context, looking for the possible evidences that are present in the construction as reader/hearing of literature. Based on a study case, we search the ways of participation of a child (girl) with intellectual deficiency in situations of offering and reception of literary texts, looking for the understanding and explication of some aspects of her processing and the building up of an initial reader. The data were taken starting from observations in moments of reading and story-telling in the period from November to December/2008 and May to June/2009 in a public school of children education, in Natal- Brazil, in which there was a registered student showing intellectual deficiency associated to Down syndrome. As research tools we used: field diary, interview scripts and video recordings. The analyses were based on research from Amarilha (2001, 2006a, 2006b), Bettelheim (2007), Coelho (2008), Iser (1996), Jauss (1979, 1994), Luria (1990a, 1990b), Vygotsky (1991, 1993), Wallon (2007, 2008) amongst others. The research showed that although expressing little verbalization and limited levels of attention, body attitudes, movements and talks of the child under investigation, denounced engagement and rendition to the sonority of the texts shared. These data gives us traces that, under a mediating action, the child with intellectual limitation can turn into a reader/hearing subject of literature, developing a sensitive and a selective attitude towards the literary text. Amongst other aspects, we identified that (1) a conception of deficiency present through the school that recognizes his/her potential of developing and learning (2) the situation of sharing, that favours a relation with the texts through the other, and (3) the relevance of orality providing the semantic paths that help the child in the building up of meaning, presenting themselves as fundamental to her/his viewing of the literary text, and, therefore, the formation of the reader. Thus, recognizing her/his capacity and possibilities, we think it is important to guarantee to the child with intellectual deficiency, a space towards interaction with the fictional text in which the child can learn and live its ludic and interactive character, to enjoy its hearing abilities, benefiting, then, from the aesthetic experience lived, mainly, in collective situations mediated through the more experient reader and shared with her/his different pairs. The research shows yet that, looking after conditions that guarantee a comfortable environment to the story hearings in the classrooms that focus on children education, being aware of a selection and the prosody of stories, the didactic contract, the attention to individual reactions, enlarge the possibility of any child deficient or not to enjoy her/himself as reader/ hearing subject of literature, engaged in its richness and magic

Os jogos com regras na perspectiva do desenho universal: contribuições à educação matemática inclusiva

To think about a school that is for everyone has been a challenge for many people connected to education worldwide demanding from researchers of each level of knowledge an association to such effort. The study presented on this paper unites itself to the voices, movements and researches of these scholars, seeking to contribute on building possibilities on which mathematics can be thought and worked on schools in order for every student to learn, whether they have some sort of deficiency, disorders, syndromes or not. This essay has the goal to investigate the possibilities of inclusive pedagogical practices mediated by math games with rules, developed and used throughout the Universal Design perspective; a qualitative research took place with a collaborative methodology that involved managers, teachers and students from a public school situated on the city of Natal/Brazil. On the investigation math games with rules were developed and made according to the Universal Design concept, starting from initial studies which articulated theoretical groundings to the reality of school and the teacher s conceptions. After that, classes using these tools were planned collectively which oriented inclusive pedagogical practices of classes from the 1st to the 4th year of elementary school. Throughout the process many instruments such as: tape recording, video footages, notes from the researcher; the teachers and the students were used for constant work evaluation and also to record the research data. In the end, the data indicated effective contributions of the mediated pedagogical practices by games with rules under the perspective of Universal Design for Inclusive Mathematics Education

Ensinar/aprender a gostar de história: saberes docentes e construção do conhecimento histórico escolar com professores de Arez-RN

This dissertation aims to analyze the relevant knowledge in countryside History teachers practice in high school and understand how these teachers themselves construct school knowledge in History, from the mobilization of different knowledge that make up teaching practice. Tree teachers from State Jacumauma High School and the researcher himself worked together in order to carry out this survey. The main theoretical-methodological elements of this research are based on assumptions of a qualitative research in cooperation. This approach was used to make possible to construct knowledge between teachers and researcher considering a less oppressive relationship as well as to help a continuous school upbringing of the individuals what can make them to understand the professional practice as an aspect in which one can exercise autonomy and criticism. The empirical research procedures were oral individual interviews, reflexive sessions and cooperative observations. Individuals speeches have presented, in some moments, teachers concerns about the educational fragmented system in which there are few opportunities to dialogic interactions among educationalists making still more difficult the dialog between school and reality surrounds it. Their assertions pointed out that relevant knowledge can be identified during the daily educational work and that they find proper reasons from the aim that each knowledge exerts in relation to the construction of professional practice. Classroom connections points out to more intense interactions between teachers and students, by recognizing affection as an important tool in order to make the interactions not so authoritarian at all. Regarding the countryside teachers understanding, the school knowledge in History is produced by sharing concerns and senses assigned by the individuals who are involved in the teaching-learning process. The referential science knowledge pervade History teaching, however they take another meaning according to specific features of the school environment. The intense and complex dynamic of the educational context makes that historical knowledge acquires specific characteristics that are constantly changing. As they change, there are some marks of elaborations and re-elaborations not only the new but also the traditional

Body art, existência e conhecimento :a percepção do corpo na Educação Física

In the Renaissance, the anatomy project a map of the body. Since then, the human body has been investigated for innumerable techniques, configuring new landscapes on the condition human being and the proper knowledge. In accordance with Merleau-Ponty (1975), All technique is body technique. It configures and extends the Metaphysical structure of our meat. In this direction, any intervention in the human body, a tattooing, a surgery or a performance, extends the perception and the directions of the existence of the subject. Merleau-Ponty (1975) still affirms, that all technique presents objective interventions. However, the body, ahead of these interventions, doesn t have to be considered only object, but subject that, from the interventions, attributes sensible and meanings through the movements, also being this its way of being in the world. Searching to extend this reflection on the discontinuities between the object body and the subject body, as well as, with the objective to reflect on the relation between the corporal techniques and the production of the subjectivity and the knowledge of the physical education, we reflect on the body art, as one technique of body that marks the exterior of the body, exteriorizing the subjectivity, to search new means to the body and that ahead of this, we believe being able to project innumerable directions for the corporal transformations in the contemporarily. As a method for our reflection in we will support them in the phenomenology. IT presents as a new ontology, in which distinction does not occur enters the operating paper of the citizen that knows and the influence of the known object. The phenomenological understanding of body will be able to contribute with the knowledge of the Physical Education, a time that gives us important arguments on the experience of the body in relation with the nature, the culture, history. To be a body is to be tied to a world that we do not possess completive, but that we do not cease to search it

As ações político-pedagógicas do Serviço de Assistência Rural-SAR

This program resumes the history of the political-pedagogic actions on the Serviço de Assistência Rural SAR, of Natal archdiocese, and analyses the contributions of this actions on the process of rural workers organization in the social movements on the countryside. The educative actions of the RAS are happening in a permanent tension between the pedagogic project of a church in change and, a pedagogy of the groups, communities and social movements, that is centered in the cultural action, in the culture lived from its condition of citizens. This research reveals that this entity fulfilled a strategic attribution for the Natal s church on the formation of the community leaderships, at a first moment and leaderships for social movements. Before the military dictatorship, the work methodology of this entity had as priority, begin from the reality leaved by the rural workers in the expectation that these became to qualify themselves for a more citizen participation in the call development. During the military regime, the entity goes measuring theirs activities in the new context, until the moment that redefines the work line. Goes then defining regions and thematic of operation supporting the fights for land, salary campaigns, women agricultural workers organizations. The pedagogy of work has as one of its supporters the Paulo Freire s pedagogy, privileging the dialog as a source of production of knowledge from the reality leaved in a permanent transformation. The actions of this entity, with the groups and social movements, produces the necessary knowledge for the organization of the rural workers while individual and social subjects of a changing world. The process of action-reflection of the activities intended, by a creative form, a permanent production of strategies of fight of the workers. Research ever, not to make accommodate itself to the new knowledge acquired in the action-reflection it is part of the pedagogical idea of this Institution. One searched in this process of formation of the man and the woman to question the reality, to create actionreflection-action spaces on the fights for a possible transition of an ingenuous conscience for a critical conscience, in view of the transformation of the structures that oppresses them

Corpo e aprendizagem em Boris Cyrulnik e em Merleau-Ponty

This research seeks to identify views of the body and learning the authors Boris Cyrulnik and Merleau - Ponty, thus tracing reflective for the educational field in several areas, with emphasis on physical education paths . We notice that the above authors present a wide collection of books, needing to develop this theoretical construct a limitation in their works. Therefore , on the theme of the body , were used mainly books The Sixth Sense , Boris Cyrulnik and Phenomenology of Perception , Merleau- Ponty , as both present in their organizational context a specific chapter on this subject . The phenomenological approach is included as path to be taken to devise this study because it is based on daily reflections that the human being perceives through his experiences with his peers and mainstream culture. The phenomenological reduction was carried out from the readings and interpretations of texts, writers and commentators, as well as approaching with life aspects of experience as a police officer and professor of ethics. The interpretation points to the understanding of body and learning that can be propagated within the Physical Education and as a way to understand and learn the constructs lived through sensitivity. The design of the body, feelings and affections of Boris Cyrulnik firm the empathetic bonds between human beings, bringing confidence to explore the world, learning through the new link with the other. This notion is close to the notion of expressive body Merleau Ponty, who holds intentions in their gestures (movements), entwining in time and space. Boris Cyrulnik and Merleau-Ponty expressed as the human being is enigmatic, lying embedded in a social and cultural world, so the experiences to traçarem existential trajetória and learning need in order to enaltercer freedom of expression as a mechanism that can be deployed in the appropriation of concepts and the criticality of the subject facing widespread theories (biological, social, anthropological , etc.) . From the reflections of the research is that recomneda Physical Education , as epistemological working area apprenticeships stemmed body movements should enable reflection on their practice, other do be done, but enabling the creation of different senses and meanings each body attitude

Efeito da estimulação transcraniana por corrente contínua anódica sobre o controle do movimento em para-halterofilistas

Introduction: The sport practiced by people with disabilities has been growing in recent years. Consequently, advances in assessment and training methods have emerged. However, the paralympic sport keeps in tow these advances, with few specific studies that consider disability as intervening factor. The transcranial direct current stimulation (tDCS) is a technique that has proven to be capable of modulating brain function. Studies show beneficial effects of tDCS on muscle strength, power and fatigue during exercise. Objective: Investigate de the effect of tDCS on movement control in para-powerlifters. Methods: Eight subjects underwent two sessions of motion capture, which previously applied the anodic tDCS or sham sessions in the cerebellum. Three movements were performed with increasing load between 90-95% of 1MR. The movements were recorded by an 10 infrared cameras system which reconstructed the 3D trajectory of markers placed on the bar. Results: There have been changes between the anodic and sham conditions over bar level (initial, final, maximum during the eccentric and concentric phase) and in the difference between the final and initial bar level. Moreover, there was difference in bar level (final and during the eccentric phase) comparing athletes amputees and les autres. Conclusion: The findings of this study suggest that tDCS applied prior to the exercise over the cerebellum in para-powerlifters acts differently according to disability

Breed and selection line differences in the temperament of beef cattle

O temperamento de quatro raças bovinas foi avaliado utilizando-se o teste de velocidade de fuga (FT) e o escore de comportamento (BST). FT foi definida como o tempo necessário para animais percorrerem uma distância de 2 m após a pesagem. BST foi baseada no comportamento dos animais na balança, amostrando-se quatro categorias de comportamento: movimentos, intensidade de respiração, vocalizações e coices. Os coeficientes de herdabilidade de FT e BST foram estimados com uso de um modelo de máxima verossimilhança restrita, considerando meio irmãos paternos. Caracu apresentou menores médias para BST do que as demais raças. Nelore apresentou resultados intermediários, seguida por Guzerat e Gyr com médias mais elevadas (p < 0,05). Resultados similares foram observados para FT, mas as médias de Caracu e Nelore não diferiram entre si. Observou-se baixa associação entre FT e BST (r p= -0,36; p < 0,01). A correlação entre rank de touros ordenados pelos seus valores preditos (p) para FT e BST foi moderada e negativa (r s = -0,63; p < 0,001). A herdabilidade de FT e BST foi de 0,35 e 0,34, respectivamente. A comparação de rebanhos Nelore com diferentes critérios de seleção para peso corporal mostrou que linhas de seleção podem modular positivamente o temperamento de Bos indicus.

Controle de atitude e altitude para um veículo aéreo não tripulado do tipo quadrirrotor

A Quadrotor is an Unmanned Aerial Vehicle (UAV) equipped with four rotors distributed on a simple mechanical "X"form structure. The aim of this work is to build and stabilize a Quadrotor aircraft in the roll, pitch and yaw angles at a certain altitude. The stabilization control approach is based on a transformation in the input variables in order to perform a decoupled control. The proposed strategy is based on breaking the control problem into two hierarchical levels: A lower level, object of this work, maintains the desired altitude an angles of the vehicle while the higher level establishes appropriate references to the lower level, performing the desired movements. A hardware and software architecture was specially developed and implemented for an experimental prototype used to test and validate the proposed control approach

Sistema de supervisão aérea baseado em navegação visual para detecção de anomalias em instalações de petróleo e gás

This work deals with the development of a prototype of a helicopter quadrotor for monitoring applications in oil facilities. Anomaly detection problems can be resolved through monitoringmissions performed by a suitably instrumented quadrotor, i.e. infrared thermosensors should be embedded. The proposed monitoring system aims to reduce accidents as well as to make possible the use of non-destructive techniques for detection and location of leaks caused by corrosion. To this end, the implementation of a prototype, its stabilization and a navigation strategy have been proposed. The control strategy is based on dividing the problem into two control hierarchical levels: the lower level stabilizes the angles and the altitude of the vehicle at the desired values, while the higher one provide appropriate references signals to the lower level in order the quadrotor performs the desired movements. The navigation strategy for helicopter quadrotor is made using information provided by a acquisition image system (monocular camera) embedded onto the helicopter. Considering that the low-level control has been solved, the proposed vision-based navigation technique treats the problem as high level control strategies, such as, relative position control, trajectory generation and trajectory tracking. For the position control we use a control technique for visual servoing based on image features. The trajectory generation is done in a offline step, which is a visual trajectory composed of a sequence of images. For the trajectory tracking problem is proposed a control strategy by continuous servovision, thus enabling a navigation strategy without metric maps. Simulation and experimental results are presented to validate the proposal

Análise operacional e econômica do processamento de madeira de Eucalitpo com Hypro em região montanhosa

O processo constante de avaliação técnica e econômica dos sistemas de colheita de madeira é intrínseco às empresas florestais, devido ao fato de corresponder a uma fase de suma importância que despende elevado investimento financeiro. No experimento deste trabalho, estudaram-se o rendimento operacional e custos operacionais e de produção do processador florestal Hypro. A análise técnica englobou estudos de tempos e movimentos pelo método de tempo contínuo. O rendimento operacional foi determinado através do volume, em metros cúbicos de madeira processada. A análise econômica incorporou os parâmetros do custo operacional, custo de processamento da madeira e rendimento energético. A análise dos dados evidenciou que o rendimento operacional por hora efetiva de trabalho foi de 38 árvores e, em metros cúbicos sem casca por hora efetiva de trabalho, de 11,68 m³ h-1, com custo de processamento de madeira sem casca de US$ 6.85 por metro cúbico.

Desenvolvimento de Uma Órtese Ativa Para os Membros Inferiores Com Sistema Eletrônico Embarcado

This work presents the development of a prototype of an intelligent active orthosis for lower limbs whit an electronic embedded system. The proposed orthosis is an orthopedical device with the main objective of providing walking capacity to people with partial or total loss of lower limbs movements. In order to design the kinematics, dynamics and the mechanical characteristics of the prototype, the biomechanics of the human body was analized. The orthosis was projected to reproduce some of the movements of the human gait as walking in straight forward, sit down, get up, arise and go down steps. The joints of the orthosis are controlled by DC motors equipped with mechanical reductions, whose purpose is to reduce rotational speed and increase the torque, thus generating smooth movements. The electronic embedded system is composed of two motor controller boards with two channels that communicate with a embedded PC, position sensors and limit switches. The gait movements of the orthosis will be controlled by high level commands from a human-machine interface. The embedded electronic system interprets the high level commands, generates the angular references for the joints of the orthosis, controls and drives the actuators in order to execute the desired movements of the user

Identificação em tempo real de modelo dinâmico de robô móvel com acionamento diferencial e zona morta

Several mobile robots show non-linear behavior, mainly due friction phenomena between the mechanical parts of the robot or between the robot and the ground. Linear models are efficient in some cases, but it is necessary take the robot non-linearity in consideration when precise displacement and positioning are desired. In this work a parametric model identification procedure for a mobile robot with differential drive that considers the dead-zone in the robot actuators is proposed. The method consists in dividing the system into Hammerstein systems and then uses the key-term separation principle to present the input-output relations which shows the parameters from both linear and non-linear blocks. The parameters are then simultaneously estimated through a recursive least squares algorithm. The results shows that is possible to identify the dead-zone thresholds together with the linear parameters
