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

This dissertation reports the results of a research which has aimed to analyze the senses attributed to the curriculum by the students of the Technical Course of Computation Maintenance and Support, organized through the Programme of Integration of the the Professional Education with the Basic Education in the Youngster and Adult Education Modality (PROEJA), at Instituto Federal do Rio Grande do Norte (IFRN), Campus Santa Cruz. It has been sought to know who the students are and to investigate their curriculum conceptions, on which the this investigation has been based on. Thus, those senses attributed by the students on their narratives have been compared to the official proposed curriculum for the Programme and to the curriculum implemented by IFRN. The current research follows the qualitative approach being led by a study case and life stories methods. In order to effective that approach, two data collecting instruments have been developed: questionnaires and semi structured interviews. The collected data has been complemented by the legal and institutional documents analysis. This study is derived from the presupposition that PROEJA s students, although are able to access school after the educational system restructuration, are still facing difficulties during their courses because of the excluding and traditional curriculum, decontextualized with their personal and work life, that is, without curriculum integration. This study has accomplished PROEJA s students characterization presenting important data for the integrated curriculum construction at IFRN and revealing that the students consider the Programme as inclusive. Nevertheless, the practices concerned to the democratic construction of the curriculum and its dialogical action indicate partial inclusion, considering that, in order to include those students indeed, it would be necessary to include them to the institutional and academic context. Contradictory situations have been detected on the course pedagogical project, considered traditional and decontextualized, especially regarding to methodological aspects. The research also allowed to increase PROEJA s investigation field as well as to contribute with a better implementation of the Programme as curricular proposal bonded to Basic and Professional Education in the Youngster and Adult Modality Education Modality

This study deals with a historical, descriptive and exploratory approach aiming to recall the origin and trajectory of the Pediatrics Hospital at Universidade Federal do Rio Grande do Norte. This research also deals with the insertion of the nursing department in the same Hospital. This was realized through existing records and discourse collected through interview of professionals-doctors, nurses, midwifes, nursing attendants and psychologists. Thus, a network was established and consisted of qualified informants, composed through reference analysis. Data treatment and analysis was performed based on the collection of oral data. The data was considered according to the font s context, all of which depending on process of comprehension and interpretation. The research was based on the main theme, through oral history used in order to build a historical background. These main themes were then subdivided and other discourses were made present such as: the historical scene, the dream came true and the insertion of nursing, present in the history construction; all of which enabled the research. Thus, in this process, it was possible to identify the most important characters of the origin of children s health services organization and assistance at Rio Grande do Norte. It was possible to perceive that this institution aimed to initiate health services that dealt with an education for future generations. This was observed through the creation of the Faculty of Medicine of Natal and as a consequence, the installation of a Pediatrics Hospital that dealt with medical education. The research made evident that the nursing contributed for a structuring of quality health assistance towards children, even though the resources and working conditions were scarce, extensive work shifts and low professional qualification. It was observed that the there was change in the category s profile, once nurses were introduced in the service. Once this happened, changes in mentality, and innovative processes as well as professional conducts were established. The distinctive relation between acting and doing of doctors and nurses were also dealt with. Thus, the first item is done towards the idealization, projection and prescription. The second issue deals with concretization in realization of something that was not projected and realized, causing suffering and unsatisfaction. At the end, it was possible to confirm that oral history is a very rich element and it is possible through subjects that build history, through their perceptation of the facts and the context in that their are inside

Analyzes the factors that unleash violence by banalization of the problems and health questions of workers in a federal public institution, in Natal/RN. It analyzes transformations in the world of the work, with its politic, social and economic determinatives and its relation to the worker health. Boarding the violence in the work enviroment and its implications to the worker health, focusing on the banalization of problems faced by the workers as a kind of violence in and with the work. It was chosen an analitic methodology with qualitative approach, through the collection tecnic and information analyzes according to the thematic oral history, with recorders of authorized personal narratives, through individual interview with a semi-structured guide. In the analyzis of results it were made empiric cathegories: the daily work enviroment and its influence to the worker profession and life; the violence presents in the work enviroment and its consequences to the worker life and health; the banalization of the social injustice, due to violence against the worker that broked their dreams concerned to the nursing contribution. The results revealed the ordinary work of these workers showing enviromental and organizational unhealthy conditions, caracterized by physical and tecnical insecurity; absence and disqualification of instrumental and human supplies; overload and complexity service; bad distribution of the duties and pressure to the deadline and productivity, producing tension, conflict and anxiety related to the users, colleagues, superiors and to the duties. In the work enviroment, it were identified a external violence, caracterized by physical and verbal aggresion, psychic suffering, worker depreciation; and internal, caracterized by: moral and psychological molestations and accupational structural violence. These kinds of violence bring consequences to the life, that is, professional, economic and moral order of factors and to the health by biological, mental and emocional factors. The banalization of social injustice during the daily work was discussed in the aspects of banalization of problems and work conditions, the health, qualification banalizations and professional valorization. The workers expectatives pointed out to the necessity of: secure conditions of work; trainning and tecnical assistance; politics of attention to the physical, mental and social health to the workers and their family. We conclude the enviromental and organizational conditions of the workers interviewed do not offer physical and tecnical security that they need to the execution of their activities, neither offer comfort or physical and psychological satisfactions. The politic the instituition has used points out to the depreciation and inhumanization of them producing feelings as unsatisfaction, frustation and indignation related to the institution and the work, bringing suffering and physical and mental sicking. We noticed the most terrible violence found in the work enviroment is the banalization of social injustice related do the problems and health of these workers, producing a slowly debility and simbolic death of their lifes. Therefore, it is necessary the implementation of a politic that promotes assurance, health and integral education, valorization and humanization of these workers

The therapeutic possibilities for chronic renal failure closely are related to the biological and social condition, and in this perspective the renal transplant is considered the best option, for providing quality of life better. This study it objectified to apprehend, by means of the rescue of the verbal history of life of the kidney transplant patients, the experiences lived since the diagnosis of the renal to the current with the current therapeutic modality. One is about a study of qualitative boarding, exploratory and descriptive, having the verbal history of life as a technique and method. The colony was formed with the ten first kidney transplant patients of the Rio Grande of the North, taken care of in the clinic of the Nephrology in the University Hospital Onofre Lopes-UFRN, located in the city of Christmas-RN. The net was composed for collaborators of both the sex, in the age band between 21 and 56 years of age, submitted it more than has one year to the renal transplant and that, in some cases, together of its familiar ones, they had voluntarily accepted to participate of the study. The first collaborator interviewed for this was excluded not to desire to participate the study more than. After approval for the Committee of Ethics in Search of the UFRN, we carry through the collection of data, by means of a halfstructuralized interview, recorded individually, in environment chosen for the collaborators. We carry through the transcription of the interviews and later we return to the interviewed ones so that the same ones made the conference, what it made possible in them to carry through the transcriation, after consecutive readings. We analyze the stories by means of the analysis of content of Bardin. Guiding the analysis of the stories of the collaborators, we find three axles thematic: Impact in the social relations, Impact in the social condition and Behavior front the illness and treatment. We conclude in this study that the loss of the renal function reed-echo drastically in the life of the collaborators, but that the acceptance of the pathological condition emerged, mainly for the support of the family and in the belief in God. The renal transplant was seen as the chance for a new life, however, so that they reach an improvement in the quality of life, other questions must be optimized, as the guarantee of constitutional laws, the rescue of the citizenship and offer of bigger support of the professionals of the health, family and society for the confrontation of the problems generated for the chronic renal illness and its treatments

The studies paths in the maze: life story of individuals with oncological diseases into use of blood transfusion in Natal has the hemotherapy as a primordial procedure to review the relationship between users of oncological health and the due ramifications. The hemotherapy looks for supply the organic needs through blood transfusion, which acquires vital function to the ones that have cancer, because it might reestablish the functionality of the organism throughout the raising of blood components. The impact over the transfusion affects emotionally and physically the users life. Aiming to reflect on these impacts, this study tried, through narratives of lives, rescue their experience since their knowledge of the disease until the time of blood transfusion using. It s about an exploratory-descriptive study, where the qualitative approach uses the theoretical-methodological reference of the oral life history to analyze a colony consisting of five users of health diagnosed with cancer, with achievement of at least three blood transfusions, the clinic Núcleo de Hematologia e Hemoterapia - UFRN, in Natal-RN. The network, in turn, was composed by employees of both sexes, regardless of age, who voluntarily agreed to participate in the study. The data collection, with approval of the Ethics Committee in Research, Liga Norte Riograndense Contra o Cancer, on the number 001/001/2012, occurred through semi-structured interviews, recorded individually in the home context that was previously chosen by employees. The methodological procedure occurred with the transcription of the interviews and their transcreations, and analysis of reports by thematic content analysis. At the reading orientation and interpretation of the employees stories, were discussed three categories of analysis: the impact on psychological REVIEW; impact on socialization and group membership, the environment and the impact of blood transfusion on treatment. Based on the narrative of the life histories of employees, we conclude that the experiences and feelings, hope and sorrow, pain and faith, even when facing a disease like cancer, bring lots of teaching and learning to health professional that deposits humanization health and reinstate hemotherapy forms of clinical critical

Several epidemics marked the lives of individuals and communities in all historical periods, and a prime example is leprosy, infectious disease marked by stigma, prejudice and social exclusion. In the past, the compulsory isolation of patients with leprosy caused serious social and psychological problems, resulting in the separation and the partial or total disruption of the family relationship. Children deprived of this living, removed often inhumanely, were kept and bred in preventoriums / educational establishments. This study aimed to: rescue the oral history of life of the children of leprosy patients that were built in preventorium Osvaldo Cruz, Natal, Rio Grande do Norte; develop a contextual analysis about these children; know the life trajectory of children of leprosy patients institutionalized in preventoriums / educational establishments; produce a documentary on the history of life of children of parents separated by leprosy; forming MORHAN of Rio Grande do Norte state; and implement the I Meeting of MORHAN of Rio Grande do Norte state. This is an exploratory and descriptive study, with a qualitative approach, approved by the ERC No. 024/024/2012 Liga Norteriograndense Contra o Câncer. We used the contributions of the method and technique of oral history of life as methodological reference. We interviewed 10 individuals egress from preventorium Osvaldo Cruz in Natal/RN, sons of former patients proven to be residents in the city, of both sexes, older than 18, with cognitive, intellectual and emotional conditions preserved. The analysis of the histories obtained from collaborators was performed in the light of Thematic Content Analysis. The results and discussions are presented through two articles which meet the proposed objectives. The first, called Contextual Analysis on the children of leprosy patients in preventoriums aimed to record the phenomenon of children of leprosy patients in preventorium through four contextual levels, which identified the need to broaden the debate on public policy in the field of leprosy as a way to enable more effective measures to propagate in the search for harm reduction and direct consequences resulting from stigma and marginalization around patients and their healthy children, egress from preventoriums. The second, Leprosy and the denial of history: the story of separated children , aimed to know the life trajectory of children of leprosy patients who were institutionalized in preventoriums / educational establishments. In this article, we discuss the research question through the establishment of three main themes: 1. Losses and damages: disintegration and reintegration into the family and denied childhood; 2. Unforgettable: remarkable things you do not forget; and 3. Expectancy in living new situations: in search of other paths and destinations. These thematic axis highlighted the negative implications for the lives of the subjects, arising from the separation of their parents, leprosy patients at the time of compulsory isolation; however, has also been shown that this separation was not decisive in their life histories, once they have succeeded in providing a new sense of these experiences and lead their lives with dignity and fortitude. It was concluded that these children demonstrated resilience as form of defense and fighting stigma and prejudice, being able to reinvent themselves and build new paths and destinations

The aim of the present study was to understand the feelings and the difficulties faced by the family caregiver in the care of the person affected by Alzheimer`s Disease (AD). It is a descriptive, exploratory study with a qualitative approach, using the oral life history proposed by Bom Meihy as the method. Data collection was conducted in the Basic Health Unit of Candelaria, located in Natal -RN, with five collaborators that carry out the role of family caregivers for people affected by Alzheimer`s disease (AD) and are members of the Group "Caring for those who Care". Caregi vers who resided with the affected family member for at least one year were selected for the study, and as a collection tool, it was opted to use semi-structured interviews via a script of open questions, recorded by permission of the collaborators, then t ranscribed and subsequently returned to respondents for checking the contents described. To analyze the results, the collaborators narrative technique was used in conjuction with the specific literature on the subject.The discussions were organized around five themes inherent to the guiding questions, and defined as follows: the incorporation of the role of the family caregiver; life before and after assuming the role of caregiver, the caregiver`s feelings and attitudes after assuming the care, difficulti es in caring, participation of the group as a foundation for caregivers. The stories showed many difficulties in the daily routine of the caregivers, and also that their participation in the group "Caring for those who Care" helps them in maintaining the q uality of their lives. The results open possibilities for the construction of new forms of approach and care for the people who fulfill the role of family caregiver contributing to strengthening of subsidies that help them better face the daily difficulti es.This study helped shed light on the fact that being a family caregiver of a person affected by AD is a suffered, exhausting and stressful condition involving much self-denial in one´s life. The situation experienced by these collaborators is considered a public health issue, and thus highlights the urgency for governmental political -social actions, besides the programs of care and health promotion for this target group.

The main objective of this thesis was the study of bracing panels of structural masonry, by applying the Finite Element Method and Strut and Tie Method. It was analyzed the following aspects: the effect of orthotropy on the behavior of the panels; distribution of horizontal forces between panels for buildings; comparison between Equivalent Frame and Finite Elements models; panels design with the Strut and Tie Method. The results showed that one should not disregard the orthotropy, otherwise this can lead to models stiffer than the real. Regarding the distribution of horizontal forces, showed that the disregard of lintels and shear deformation leads to significant differences in the simplified model. The results showed also that the models in Finite Element and Equivalent Frame exhibit similar behavior in respect to stiffness of panels and stress distribution over the sessions requested. It was discussing criteria for designing Strut and Tie Method models in one floor panels. Then, the theoretical strength these panels was compared with the rupture strength of panels tested in the literature. The theoretical maximum strength were always less than the rupture strength of the panels obtained in tests, due to the fact that the proposed model cannot represent the behavior of the masonry after the start of the panel cracking due to plasticization of the reinforcement

Usually masonry structures has low tension strength, hence the design to flexural efforts can results in high reinforcement ratio, specification of high unit and prism strength, structural members with larger section dimensions and modification in structural arrangement to be possible to use masonry members. The main objective of this study is to evaluate the stiffness, the efforts distribution and the effect of horizontal elements (girders) and vertical elements (counterforts) distribution on the behavior of masonry blocks retaining walls. For this purpose, numerical modeling was performed on typical retaining wall arrangements by varying the amount and placement of horizontal and vertical elements, beyond includes elements simulating the reactions of the soil supporting the foundation of the wall. The numerical modeling also include the macro modeling strategy in which the units, mortar and grout are discretized by a standard volume that represents the masonry elastic behavior. Also, numerical model results were compared with those ones of simplified models usually adopted in bending design of masonry elements. The results show horizontal displacements, principal and shear stresses distribution, and bending moments diagrams. From the analysis it was concluded that quantity and manner of distribution of the girders are both important factors to the panel flexural behavior, the inclusion of the foundation changed significantly the behavior of the wall, especially the horizontal displacements, and has been proposed a new way of considering the flanges section of the counterforts

Bayesian networks are powerful tools as they represent probability distributions as graphs. They work with uncertainties of real systems. Since last decade there is a special interest in learning network structures from data. However learning the best network structure is a NP-Hard problem, so many heuristics algorithms to generate network structures from data were created. Many of these algorithms use score metrics to generate the network model. This thesis compare three of most used score metrics. The K-2 algorithm and two pattern benchmarks, ASIA and ALARM, were used to carry out the comparison. Results show that score metrics with hyperparameters that strength the tendency to select simpler network structures are better than score metrics with weaker tendency to select simpler network structures for both metrics (Heckerman-Geiger and modified MDL). Heckerman-Geiger Bayesian score metric works better than MDL with large datasets and MDL works better than Heckerman-Geiger with small datasets. The modified MDL gives similar results to Heckerman-Geiger for large datasets and close results to MDL for small datasets with stronger tendency to select simpler network structures

The red ceramics and structural ceramics, as they are known, include ceramic materials made by blocks of seals and structures, bricks, tiles, smail flagstones manacles, rustic floors and ornamental materials. Their fabrication uses raw material such as clay and clay sites, with some content of impurity. It has good durability and mechanical strength to compression, low cost, making it one of the mainly used materials in civil engineering. The incorporation of many industrial activities residue to ceramic products is a technological alternative for reducing the environmental impact caused by its carefree disposal. This incorporation can promote chemical change and inertness of metals from residue, by fixation in the glassy phase of ceramic during the burning stage. The main aim of this project is to study the technical feasibility of the addition of ceramic oven ash into formulations of mass for structural ceramics. In this project two kinds of clay (plastic and non-plastic) were used, as well as the ash from firewood used in the process of burning of structural ceramics. A group of experiments was outlined, which permitted the evaluation of the influence of the burning cycle in different temperatures of the ash content in formulations for ceramic blocks through technological properties, mechanical behavior and microstructure. Five samples were processed of each one of the masses of plastic and non-plastic clay without addition of ash and with addition of ash on the percentages of 10 % and 20 %, for temperatures of 850 °C, 950 °C, 1050 °C and 1150 °C, obtained through sinterization process. Among the studied compositions, the one which presented best performance was the mass of clay with 10 % of ash, at temperature of 1150 °C, with the smallest absorption of water, the smallest apparent porosity, specific apparent mass a bit over the others and greatest mechanical resistance to flexion. The composition made confirmed the technical feasibility of the use of ash in the mass for structural ceramics with maintenance of its necessary characteristics for its purposes

There are a number of damaging mechanisms that various materials can suffer in service. However, when working with polymer composite materials, this is something that requires analysis, especially when exposed to adverse environmental conditions. Thus, the objective of the present thesis is the study of the direct influence of environmental aging and the form of hybridization of the reinforcement woven on the structural stability, surfacedegradation and fracture process of polymer composites laminates. For this, the development of two polymer composite laminates was necessary, where one of them was reinforced with a bi-directional woven with hybrid strandsofkevlar-49/glass-Efibers, and the other also with a bi-directionalwoven, however with weft and warpformed of alternating strandsof Kevlar-49 fibers and glass-E fiber The reinforcementwoven are industrially manufactured. Both laminates use a polyester resin as a matrixand are made up of four layers each. All laminates were industrially prepared by the hand lay-up method of manufacturing. To do this, test specimens were manufactured of the respective laminates and submitted to environmental aging accelerated through the aging chamber. They were exposed to alternating cycles of UV radiation and moisture (heated steam) for a standard defined period. At the end of the exposure period the specimens were subjected to mechanical tests of uniaxial tensile and bending in three points and to the characterizationsof the fracture and surface deterioration. In addition, they were submitted to a structural degradation assessment by the measurement of mass variation technique (MMVT) and the measurement of thickness variation technique (MTVT), this last technique being developed in this thesis. At the end of the analysis it was observed that the form of hybridization of the reinforcement woven and the aging process directly influence with losses or gain in mechanical properties, with losses in the structural degradation and in the formation and propagation of damage mechanism of the developedcomposite laminates
