Programa alfabetização solidária: um estudo sobre a experiência no município de Lagoa de Pedras/RN (1997 - 2003)

The educational reform of the 90 s was tainted by the objectives of the fiscal adjustments, resulting in the redefinition of the state s role in the financing and offering of teaching services, and bringing about a shuffling of the responsibility between the public and private sectors to promote education to young people and adults. The 90 s also highlighted the proliferation of providers and the multiplication of Educational Programs for Youths and Adults (EJA), implemented through partnerships between governmental and nongovernmental agencies. During this period of time, the agenda of educational responsibilities concerning analphabetism was organized in a process of decentralized of the state, with the following political, social, and economic objectives: to reduce the public deficit, increasing public savings and the financial capacity of the state to concentrate resources in areas considered indispensable to direct intervention; to increase the efficiency of the social services moffered or funded by the state, giving citizens more at a lower cost, and spreading services to more remote areas, expanding access to reach those most in need; to increase the participation of citizens in public management, stimulating communitarian acts as well as developing efforts towards the effective coordination of public figures in the implementation of associated social services. Thus, Assistance Programs co-financed by the government try to deal with the problem of analphabetism. Within the sphere of the 90 s educational policy decentralization, we come to see how the agenda dedicated to the reduction of analphabetism was formed by the Solidarity Alphabetization Program (PAS). Between 1997 and 2003, the latter agenda s decentralizing proposal was integrated in the management partnership for the operationalization of tasks and resources faced with the execution of the formal objectives. In this study, we identify the dimensions of the implantation and progress of the tasks carried out by PAS, in the municipality of Lagoa de Pedras/RN. However, we consider these Programs to assist in the process without guaranteeing the reduction of the causes or substituting the responsibility of the system once the monetary resources for program maintenance provided by the partners is exhausted

Prevalence and histopathology of Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae) in Prochilodus lineatus Valenciennes, 1836 from Volta Grande Reservoir, MG, Brazil

O presente trabalho estudou a prevalência e a histopatologia de Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae) em curimbatá, Prochilodus lineatus Valenciennes, 1836. Dezoito peixes com comprimento total médio de 46,7 + 1,1 cm e peso médio de 1.674,8 + 75,6 g foram coletados com rede, bimestralmente, de dezembro de 1995 a dezembro de 1996 na usina hidrelétrica do Reservatório de Volta Grande (Cemig), Minas Gerais, Brasil. Dos peixes analisados, 15 estavam infectados com acantocéfalos no intestino (prevalência de 83,3%). A maior intensidade média ocorreu em agosto de 1996, com 66,5 (16 a 208) parasitos. A análise histopatológica revelou completa descamação do epitélio intestinal com severa hiperplasia e hipertrofia das células caliciformes. Observou-se, ainda, forte reação inflamatória na submucosa, deslocamento de feixes, associado a edemas, bem como infiltração mononuclear e eosinofílica.

Trajetória de vida de ex-portadores de hanseníase com histórico asilar

Hansen's disease, despite significant advances regarding the diagnosis, treatment and control still carries an immense burden of stigma as a result, mainly of its socio-historical marked by prejudice and isolation of patients, translated by suffering, abandonment and psychosocial problems. Thus, the study set out to rescue the life stories of former leprosy patients with a leprosarium history; recovering the life trajectory stories of these former patients and to identify common factors to these life stories. Exploratory-descriptive study with a qualitative approach, using the Life History Research Methodology. The sample was composed by twelve former leprosy patients who lived while undergone treatment in the Colony Hospital St. Francisco de Assis, located in Natal, Rio Grande do Norte. The network was composed without considering sex and age limit, patients that lived in the Colony Hospital for at least six months and who agree to participate freely in the study. The subjects with special physical needs (hearing) or mental disabilities and those who do not agree to participate were excluded. A semi-structured interview was used to data collection, the interviews were recorded in the household context of individual, residents in neighborhoods Felipe Camarão, Km 6 and Jardim America, more precisely at Nova Vida village, all located in that district. The data collected were subjected to the technique of thematic content analysis. This study had obtained an appropriate consent of the UFRN Research Ethics Committee under the protocol No. 016/2010. After extensive and careful readings of life stories we identified three themes that guided the data analysis: behavioral stages, social exclusion and, stigma and prejudice. Thus, it is clear that the practice of compulsory confinement of patients in nursing homes and the mythical image of Hansen's disease as being ugly and deformed, contributed to solidifying the historical stigma surrounding the disease and its patients, raising in society and family attitudes and feelings of exclusion, prejudice and fear. Moreover, there are remarkable stories in the lives of these interviewed reporting suffering, denials, anger that reverberate to this day, affecting negatively the social and family reintegration of these individuals. As a result, we see the need for managers and local health professionals, especially nurses, rethink existing strategies for social rehabilitation of the patient and ex-leprosy patient aiming to suppression unjust and harmful stigma rooted in image and stories of these individuals

As ações de controle da tuberculose na atenção primária à saúde: a visão do doente

Tuberculosis is a disease of great impact on the world context today. In Brazil, the disease management was directed to the Primary Health Care, due to the determination of the Ministry of Health to decentralize health actions for primary care. Thus, since the actions of diagnosis, treatment and control of the disease should happen in this context, however, there are still many barriers that may hinder the realization of these determinations. This study aims to analyze the development of tuberculosis control activities conducted in the services of primary health care from the patient's vision. This is a descriptive, cross-sectional and quantitative study. The population consists of 517 tuberculosis patients treated in units of Primary Health Care in the city of Natal-RN; the sample consists of 93 TB patients. The collect instrument is structured, based in The Primary Care Assessment Tool (PCAT), validated in Brazil and adapted to assess attention to TB in Brazil, with modifications. This instrument was divided into blocks: the first one describes the socio-demographic information of patients with TB and the second one describes the health services working in control, diagnosis and treatment of TB, and includes issues related to the dimensions of primary care: access, bond, services, coordination of care, guidance to the community and family focus. For quantitative analysis, were built indicators for each item of the instrument. The response patterns are followed according to the Likert scale, which was assigned a value between one and five meant that the degree of preference relation (or agreement) of the statements. Values between 1 and 3 were considered unsatisfactory for the indicator, between 3 and less than 4, regular, and between 4 and 5, satisfactory. The results indicate that 62.37% of patients are male, 27.96% aged 41 to 50 years old, and 34.41% unemployed, with low education and low family income. It was found that the reference hospital services are the front door to the patient (59.14%), and are also the local diagnosis of the disease (72.04%). On access, the conditions satisfactory found are: the number of times the patients need to pick up the health care issue, the marking and the facility to get a consultancy in the HS, assistance provided without harm to the individual's attendance labor and facilities related to the proximity between the residence and services; were considered unsatisfactory conditions related to travel to the HS, and on hours and days of operation of services. As for the cast of services were satisfactory and regular actions related to the request for examination to become viable in the first HS, the availability of pot to perform smear and medicines for the treatment, as well as consultations control and receiving information about the disease and the treatment performed; it is considered unsatisfactory the performance of the home care for patients with TB by the HS that acts as a front door, for implementation of the Directly Observed Treatment (DOT), home visits during treatment, the provision of transportation allowance to the patient and the existence of groups for TB patients. Regarding the coordination of care, resulted in regular the action of referring the patient to other HS to obtain examinations, and as unsatisfactory referral to obtain medications. The relationship bond between patient and health team were considered satisfactory in the majority or regular. As for the family and community focus, is satisfactory only the indicator relating to questions from professionals to the patient about the existence of respiratory symptoms in the family. It is considered that there is need for greater commitment from government entities to the incentives required to TB control, as well as the availability of necessary inputs and training of human resources working in the PHC in the ongoing quest to strengthen primary care, as a place of broader host needs to contact the user with the actions and health professionals. It is recommended the adoption of management mechanisms possible to expand the capacity of the health PHC, promoting the service delivery to the user and ensuring attention to population health.

Vivências compartilhadas de filhos separados pela hanseníase no RN a luz da história oral de vida

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

Trajetória de profissionais da saúde de um hospital colônia para hanseníase

Leprosy as a public health problem , there is still quite some time , even with treatment for decades . Your health-disease process is marked by a historical backdrop of stigma , prejudice, social exclusion and authoritarian decisionducts , in order to extinguish the disease milieu under the regime of compulsory confinement of the patient. In this perspective , the Brazilian public health twentieth century adopted policies of compulsory isolation , which meant that those who receive a diagnosis of leprosy were isolated from society and their families in hospitals colonies . Objective is, to the study, rescue the trajectory of health professionals in the Colony Hospital St. Francis of Assisi , in Natal / RN ; Identify the policy was perceived as compulsory institutionalization imposed for leprosy patients by health professionals ; describe the behaviors Professional Hospital adopted in Cologne ; Retrieve information about the existence and functioning of the Hospital and Create a documentary of historical fragments of leprosy from the point of view of professionals from a former colony. Exploratory - descriptive method with a qualitative approach , using the methodological framework thematic oral history was used . Obtained approval by the IRB of the Federal University of Rio Grande do Norte, under Protocol No 461 403 and CAAE 19476913.9.0000.5537 . Be interviewed during the period of November and December 2013 , five health professionals who worked in the hospital colony , using audio recorder and images to capture and record the statements. The interviews were transcribed , textualized, transcriadas and sent to reviewers to step conference of the reports. Subsequently , analysis of the stories was made from the proposed content analysis of Bardin . The results and discussion are presented in the form of article: Opinion of nursing professionals who worked in a hospital for leprosy colony , which aimed to : identify the opinion of nurses who worked in hospital colony on the lives of patients . In this article, three main themes were highlighted and discussed from the reports of colaboradoes : I - The socialization process of internal II - 16 Prejudice , stigma and discrimination III - Social exclusion versus inclusion . We conclude that , in the context of the colony hospital, the performance of health professionals contributed significantly to that stigma , prejudice and social exclusion would be minimized and that the experience of asylum seekers in the colony were not seen more traumatic

Avaliação do desempenho de uma cortina de estacas espaçadas, atirantada, em areia

It is presented the analysis of a retaining wall designed for the basement of a residential building, located in Natal/RN, which consists in a spaced pile wall, anchored by tiebacks, in sand. This structure was instrumented in order to measure the wall s horizontal movements and the load distribution throughout the anchor fixed length. The horizontal movements were measured with an inclinometer, and the loads in the anchors were measured with strain gages, installed in three places throughout the anchor fixed length. Measurements for displacement were done right after the implementation of each stage of the building and right after the conclusion of the building, and the measurements for loads in the anchors were done during the performance test, at the moment of the locking off and, also, right after the conclusion of the building. From the data of displacement were obtained velocity and acceleration data of wall. It was found that the time elapsed on braced installation was decisive in the magnitude of the displacements. The maximum horizontal displacement of wall ranged between 0,18 and 0,66% of the final depth of excavation. The loads in the anchors strongly reduced to approximately half the anchor fixed length, followed an exponential distribution. Furthermore, it was found that there was a loss of load in the anchors over time, reaching 50% loss in one of them

Um método para determinação da profundidade combinando visão estéreo e autocalibração para aplicação em robótica móvel

This work proposes a method to determine the depth of objects in a scene using a combination between stereo vision and self-calibration techniques. Determining the rel- ative distance between visualized objects and a robot, with a stereo head, it is possible to navigate in unknown environments. Stereo vision techniques supply a depth measure by the combination of two or more images from the same scene. To achieve a depth estimates of the in scene objects a reconstruction of this scene geometry is necessary. For such reconstruction the relationship between the three-dimensional world coordi- nates and the two-dimensional images coordinates is necessary. Through the achievement of the cameras intrinsic parameters it is possible to make this coordinates systems relationship. These parameters can be gotten through geometric camera calibration, which, generally is made by a correlation between image characteristics of a calibration pattern with know dimensions. The cameras self-calibration allows the achievement of their intrinsic parameters without using a known calibration pattern, being possible their calculation and alteration during the displacement of the robot in an unknown environment. In this work a self-calibration method based in the three-dimensional polar coordinates to represent image features is presented. This representation is determined by the relationship between images features and horizontal and vertical opening cameras angles. Using the polar coordinates it is possible to geometrically reconstruct the scene. Through the proposed techniques combination it is possible to calculate a scene objects depth estimate, allowing the robot navigation in an unknown environment

Modelagem de máquina de indução trifásica sem mancais com bobinado dividido

This work presents a model of bearingless induction machine with divided winding. The main goal is to obtain a machine model to use a simpler control system as used in conventional induction machine and to know its behavior. The same strategies used in conventional machines were used to reach the bearingless induction machine model, which has made possible an easier treatment of the involved parameters. The studied machine is adapted from the conventional induction machine, the stator windings were divided and all terminals had been available. This method does not need an auxiliary stator winding for the radial position control which results in a more compact machine. Another issue about this machine is the variation of inductances array also present in result of the rotor displacement. The changeable air-gap produces variation in magnetic flux and in inductances consequently. The conventional machine model can be used for the bearingless machine when the rotor is centered, but in rotor displacement condition this model is not applicable. The bearingless machine has two sets of motor-bearing, both sets with four poles. It was constructed in horizontal position and this increases difficulty in implementation. The used rotor has peculiar characteristics; it is projected according to the stator to yield the greatest torque and force possible. It is important to observe that the current unbalance generated by the position control does not modify the machine characteristics, this only occurs due the radial rotor displacement. The obtained results validate the work; the data reached by a supervisory system corresponds the foreseen results of simulation which verify the model veracity

Com o propósito de avaliar a colhedora Penha CLM-350, visando fornecer subsídios aos projetos e usuários, realizou-se o presente trabalho, onde foi estudada a eficácia do sistema espigador, determinando-se a porcentagem de milho colhido para os diversos tratamentos estudados. Definiu-se um parâmetro adimensional U, que é a relação entre a velocidade periférica dos roletes e a velocidade de deslocamento da colhedora. Procurou-se relacionar as diversos tratamentos U, com os valores percentuais de grãos de milho colhidos e perdidos no solo. Os resultados foram estudados através da análise de variância, empregando-se o teste F, aos níveis de 1% e 5% de probabilidade e o teste Tukey para a comparação estatística entre as médias.

UMEB - Unidade Móvel para Ensaio da Barra de Tração

Um equipamento denominado Unidade Móvel de Ensaio da Barra de Tração - UMEB, foi desenvolvido na FCA/UNESP de Botucatu para realizar ensaios de tratores em solo agrícola. Construída a partir de um reboque (trailer), a UMEB foi adaptada para servir como carro dinamométrico instrumentado, utilizado na avaliação do desempenho de tratores submetidos a ensaios na barra de tração. Sua massa total é de 10.500 kg sustentados por um conjunto de seis rodados pneumáticos. Ensaios de campo mostraram que a UMEB proporcionou força de tração acima de 35 kN, mantendo-a constante, em diferentes condições de superfície do solo, mesmo quando a velocidade de deslocamento foi modificada.

Avaliação operacional do controle mecânico de plantas aquáticas imersas no reservatório de Jupiá

O presente trabalho foi realizado com o objetivo de estudar a coleta e o descarte de plantas aquáticas em diferentes locais e infestações do sistema Tietê/Paraná, no reservatório de Jupiá. A operação foi realizada com auxílio de instrumentação instalada em uma colhedora de plantas aquáticas, com sistema de GPS dotado de sinal de correção diferencial. Os tempos gastos para carregar e descarregar a colhedora foram determinados por cronometragem, e a distância do ponto final de coleta ao ponto de descarte e o tempo de deslocamento, por cronometragem e uso de GPS convencional. em algumas coletas foram demarcados polígonos, instruindo-se o operador a trabalhar exclusivamente na área correspondente. A interpretação dos resultados permitiu determinar a participação do tempo de coleta em relação ao tempo total de operação, indicando um valor significativo do ponto de vista operacional (>70%). Considerando o descarte em áreas infestadas com taboa, o deslocamento total médio foi de apenas 383 m, com gasto médio de 200,96 s. Os valores de capacidade operacional da colhedora oscilaram entre 0,23 e 1,60 ha h-1, indicando valor médio de 4,48 ha dia-1. A maior limitação à capacidade operacional associou-se à velocidade média de deslocamento, com maior agravante em áreas com altas infestações ou profundas. Considerando-se o deslocamento da colhedora, houve grande dificuldade de orientação em condições normais de operação, inviabilizando a manutenção de espaçamentos uniformes entre as faixas de coleta e sobrepondo as passagens. Conclui-se que a avaliação operacional indicou a impossibilidade de operar a colhedora sem o auxílio de um sistema de navegação que permita orientar a sua movimentação nas áreas de controle.

Desenvolvimento de equipamentos para o mapeamento de áreas infestadas por macrófitas aquáticas imersas

Foi desenvolvido um conjunto de equipamentos com o objetivo de mapear as áreas infestadas por macrófitas aquáticas, auxiliando operações de manejo mecânico, as quais são realizadas por uma colhedora desenvolvida especificamente para essa finalidade. O conjunto de equipamentos foi constituído por um GPS com programa de correção diferencial, acoplado a um palmtop, um sistema com dois teclados ligados em dataloggers e um transdutor de deslocamento linear LT. O GPS, através do palmtop, proporcionava o mapeamento da área de deslocamento, auxiliando o operador na movimentação da máquina, otimizando a operação e evitando, dessa forma, a sobreposição das faixas de coleta na área a ser manejada. Um dos teclados monitorava a movimentação e operação da colhedora, além da presença de obstáculos, como tocos e bancos de areia, enquanto o outro gerava dados sobre a presença de determinada espécie de planta, como E. densa, E. najas e C. demersum, além do nível de infestação destas plantas. O transdutor, instalado na plataforma frontal da colhedora, se movimentava linearmente, gerando informações sobre a profundidade da coleta realizada. Dessa forma, pôde-se observar que o desenvolvimento desse conjunto de equipamentos foi de grande utilidade e auxiliou a operação de controle mecânico de áreas infestadas por macrófitas aquáticas imersas, possibilitando, assim, o planejamento de operações de manejo e controle subseqüentes.

Análise espacial da distribuição longitudinal de sementes de milho em uma semeadora-adubadora de precisão

In the operation of sowing with planter numerous factors interfere with the establishment of the plant stand, among them, the longitudinal distribution of seeds depending on the displacement speed can significantly affect crop productivity.The present study aimed the evaluation of longitudinal distribution of maize seeds in two different speeds of dislocation of a precision grain drill, through classical and geostatistics. A regular grid sample, totalizing 100 points in each area, was built with 10-meter distance among the points. Each sample point comprised 3.6m(2) (1.8 x 2.0) where the percentage of acceptable, double and fail spacing among the plants was measured after sowing at 4.58 and 5.94 km h(-1) speed of dislocation. Classical and geostatistics were used for data analyses. The percentage of acceptable and failed spacing has shown significant difference between 4.58 and 5.94 km h(-1) speed. The results has shown absence of spatial dependence regarding the percentage of the studied spacing (acceptable, fail and double) at both speeds, showing that studies and statistical inferences can occur based on parameters of classical statistics for distances higher than the shortest one used in the sampling.
