Avaliação da sobrecarga do cuidador informal no desempenho de suas funções à pessoa idosa dependente, no Concelho de Santana

O processo de cuidar do idoso dependente é multidimensional e executado por cuidadores formais e informais. Sempre foi uma função designada à família onde havia divisão de tarefas entre os diversos membros,. O objetivo do estudo foi avaliar a sobrecarga dos cuidadores informais no desempenho de suas funções à pessoa idosa dependente, no concelho de Santana; estimando o nível de dependência dos idosos e determinando a satisfação, as dificuldades, o coping e a sobrecarga dos cuidadores. A população acessível foi constituída por 69 cuidadores informais. O estudo foi, transversal, descritivo - correlacional. O formulário inclui questões de caracterização sociodemográfica e escalas: de satisfação, de dificuldades em cuidar, e de estratégias de coping (Nolan et cols,1998), de percepção da sobrecarga do cuidador (adaptação de Zarit et cols,1983) validadas para Portugal (Sequeira 2007). Utilizou-se a Escala de Barthel (Mahoney; Barthel,1965) para determinar a dependência dos idosos. Dos resultados realçamos: a maioria dos cuidadores é mulher, casada, com escolaridade até o 6º ano, baixo nível sócio económico sendo familiar do idoso cuidado. Dos cuidadores, 38% são-no entre um a quatro anos e 72,5% cuidam 12 horas/dia A etapa do ciclo vital familiar dos cuidadores é o fim da vida (76,8% ). Dos idosos cuidados, 68% era muito dependente. Dificuldades no cuidar incluíram: restrições sociais, exigências e reações ao cuidar e estratégias de coping mais limitadas. Os cuidadores tendiam sentir-se satisfeitos com o cuidado. Não sofrem sobrecarga 36,3 % mas, 63,7% refere-a ligeira e intensa. Nos homens realçou-se a intensa e nas mulheres a ausência de sobrecarga. Ela foi mais significativa entre os analfabetos, os que sentiam dificuldades, os mais carenciados economicamente e que não gozavam de férias. Evidencia-se a importância da intervenção junto aos cuidadores informais por parte da rede formal de apoio para prevenção da sobrecarga.

Atividades investigativas: utopia ou realidade na aprendizagem significativa da matemática?

A matemática, infelizmente e de uma forma errada, ainda é encarada por muitos como uma ciência que é acessível apenas para alguns “iluminados”. Segundo a frase célebre de Paulo Freire, “Não há saber mais ou saber menos há saberes diferentes” e é este tipo de filosofia que é necessário incutir nas nossas escolas e na sociedade. A meu ver, as atividades investigativas vão ao encontro do pensamento de Paulo Freire, uma vez que, neste tipo de atividades, deve ser dado enfoque aos diferentes percursos e saberes. A matemática deveria ser encarada como uma disciplina que educa para a vida – educação matemática. Neste sentido, ela deveria ser trabalhada em diferentes contextos para que os alunos alarguem o seu campo de visão e utilizem a matemática de uma forma crítica e em prol do seu bem-estar. O presente estudo visou compreender de que forma as atividades investigativas contribuem para a aprendizagem significativa da matemática e qual o seu contributo na formação de alunos autónomos e com competências para pensar e agir. A investigação incidiu sobre a prática matemática dos alunos quando realizavam atividades investigativas sobre a unidade temática das semelhanças, nomeadamente, sobre figuras semelhantes, razão de semelhança e critérios de semelhança de triângulos, onde foi utilizada uma metodologia qualitativa de natureza descritiva através da observação participante. O estudo foi efetuado numa turma do sétimo ano e teve por base três propostas de trabalho, sendo que a primeira foi mais de carácter introdutório. Nestas atividades, foram utilizados materiais manipuláveis e o Microsoft Excel no sentido de motivar os alunos e facilitar a compreensão dos conteúdos trabalhados. Os materiais utilizados despertaram um enorme interesse nos alunos, os quais começaram logo a explorá-los, manuseando-os livremente sem qualquer objetivo pré-definido, isto é, antes de se inteirarem do propósito da atividade. As atividades investigativas aliadas aos materiais manipuláveis são uma maisvalia na aprendizagem dos alunos uma vez que o conhecimento é construído de uma forma natural através de um processo espontâneo e dinâmico, consequentemente, significativo. Com a realização de atividades investigativas, são proporcionados aos alunos momentos de exploração e de investigação aleatórios, culminando numa aprendizagem de improviso, no sentido em que esta não obedece a regras pré-definidas e estimula e desenvolve o raciocínio dos alunos.

Visitabilidade-vivenciabilidade em assentamentos informais : um estudo da acessibilidade de percursos urbanos no Conjunto Santa Terezinha em Fortaleza-CE

This research approaches the issue of accessibility in informal settlements, seeking for the challenges and limits defined by informal urban settings, about the application of accessibility parameters. Take the empirical universe as the Conjunto Santa Terezinha, located in Fortaleza- Ce. Initially, the study presents a reflection about the housing issue in Brazil and the informal settlementes in view of the Right to the City. In this sense, the main references are, the works of Suzanne Pasternak (2008), Nabil Bonduki (1998) and Erminia Maricato (1996-97), among others. Follows with the discussion of the concepts and classifications of this type of settlement, making a content analysis of legislation and regulations relating to accessibility and proposed the discussion of the accessible route as the right strategy for the city. In another step, the methodology of 'walking together' created by Dischinger (2000) was applied in a passage previously chosen, which the researcher follows the disabled person during the journey through city making records like photos and video. The comments and perceptions are compared to the spatial analysis of urban morphology, made from the method of Del Rio (1990) and Panerai (2006), and the parameters of NBR 9050. Knowledge of the area is enriched by the methodology of the production of space made by Henri Lefebvre in his book 'The production of space' (1974) with these categories: space conceived, perceived and lived. Another key reference of this author it s the book 'The Right to the City' (991), which allowed in-depth reflections on the social function of town. In conclusion, the study finds that to guarantee a minimum access conditions in informal sittlements it´s necessary to know the specifics of their morphology, their relations and urban practices in view of the visitability- experiencebility, describing it as complementary concepts

As repercussões dos serviços hospitalares em diferentes contextos: uma análise de profissionais de saúde

This study has as general object: to verify as the health professionals that work in different hospitals evaluate the hospital services; and specific objectives: identify how health professionals evaluate the work conditions in different hospitals and verify the central nucleus and the peripheral elements of the social representations elaborated by these professionals about these institution. This is a descriptive study realized in Natal, capital of Rio Grande do Norte. Were collected 213 questionnaires. Concerning the evaluation of the health services, high averages had been verified in the philanthropic hospital, for example, quality of the customer service. At the state hospital was observed lowest ones: respect to the privacy of the patients. Similar results were found about work conditions. It was observed as central nucleus the categories Overcrowded and Humanized care, in the state and philanthropic hospital respectively, and as peripheral elements Low wages and Overcrowded. Being thus the conflicts in this scene are inevitable because of the poor structure of some public hospitals, however, these problems can be foresee and solvable if the hospital has a free expression channel accessible to all agents. The evaluation has to become integrant part of the culture of the organization, a time that this will guide the steps in direction to the best quality in the hospital assistance

Crescimento e nutrição de plantas de leucena (Leucaena leucocephala (Lam.) R. de Vit) sob salanidade

Excessive salt can to promote water soil retention, reducing your availability to plants. Besides, they can interfere in protoplasm metabolism. The plants ability to survive in salinity conditions is an important factor to geographic distribution and agriculture in salinized regions. The objective of this work was to verify the effects of the NaCl in the growth, dry matter distribution and N, K, Ca, Mg, Na, and Cl content in young plants. The experiment was conducted in 'Leonard' pots, with nutrient solutions, with NaCl ( 0, 25, 50 and 100 mmol L(-1)). Increasing of NaCl concentration reduces growth and total dry matter. There was an increase of N and K content, in shoots, and N and Mg content in roots. There was an reduction in Mg content in shoots, and reduction of Ca content in roots with increasing of NaCl. Leucaena plants were inefficient to exclude Na and Cl, in shoots principally.

Juizados especiais federais e o acesso à justiça federal no Rio Grande do Norte

This work aims to study the performance of Juizados Especiais Fedrais (JEF) in Rio Grande do Norte and its contribution to the facilitation of access to justice by ordinary citizens. Created in 2001, the JEF looks simplify and reduce the procedural steps and reduce the number of appeals referred to the courts so that justice is possible to provide a more agile. In this sense, are designed to contribute to the democratization of access to justice. In Rio Grande do Norte, the JEF was established and began operating in January 2002, serving in causes civil pension. From 2005, the Court began to receive all types of civil cases and have a virtual system of processing of cases. Among the methodological procedures used in conducting research, highlight the documentary survey in the virtual site of the Federal Justice of RN, to obtain data on the shares tried and sentenced in the years 2005, 2006 and 2007, using the quantitative research. Were also conducted interviews with federal judges, using the qualitative research method. Among the results, we conclude that the Juizado Especial Federal in Rio Grande do Norte is complying with its objective of making justice more accessible and responsive to ordinary citizens, especially the short time that an action leads to the entry in the Court to be given the sentence

Corpo e gestualidade :o jogo da capoeira e os jogos do conhecimento

In the direction of questing a sociology that considers the flesh dimension of the existence, that favors to think the body while place of the production of the knowledge, our itinerary of research is characterized for the reflection on the gesture of the body as power of life and production of knowledge, recognizing the precision of the gesture as a privileged breach of comment of the collective life, of the projection and registration of the culture, of the symbolic, of the sensitivity. Our problematic can be meet in the possibility to enhance an open and sensible rationality, tattooed in the body and accessible for the gestures, that its materialized in the relations of the human being with the other and the world, in singular and collective relations. Therefore, the gesture, constructed in the intention the experience of the body, can tell us about the human being, the society and the culture, therefore the sensed of the gestures is constructed from the established and recognized mutual actions for the citizens. It is in this field of production of the knowledge, of knowing of the meat that we direct our perception, in the challenge to immerge into the intention of the gesture in the capoeira game. Of the methodological point of view, for the analysis of the gestures of the capoeira, therefore, of the body as knowledge power, we consider registers of images as well as narratives registers of the universe of the capoeira, as well as my experience of more than seven years in the group of capoeira cordão de ouro1. A epistemological exercise has as support a qualitative research where parts of the quantity of images of the investigated group, as well as interviews, daily registers in of field and over all my experience of life next to the group and to the capoeira, in intention to recognize symbols tattooed in the body and for it produced in the inter subjectivists relations. We search therefore, to evidence sensible and meanings drawn for the gesture and evidenced by the look of the researcher. We presents as objectives of this inquiry to nuance ribbings around of the social and cultural elements in the production of the knowledge of the body, of the gesture, weaveeed for the sensible rationality

Do olhar inquieto ao olhar comprometido: uma experiência de intervenção voltada para a atuação com alunos que apresentam paralisia cerebral

Compte tenu de l importance de la formation des enseignants pour répondre, de nos jours, aux besoins des élèves dont les caractéristiques marquantes sont la diversité et la différentiation, desquels nécessairement font partie , à un échelon croissant, des personnes atteintes d une déficience quelconque ; devant le constat que les actuelles politiques d éducation, en fonction de leurs limitations, peuvent être considérées comme un des principaux facteurs qui entravent la concrétisation d un vrai processus d inclusion de ces personnes ; compte tenu, encore, que le confront des situations éducatives concernant le processus d inclusion de ceux ayant des déficiences physiques, notamment lorsqu il s agit d élèves atteints de paralysie cérébrale, engendre chez les enseignants un état de troublante inquiétude du fait de ne se sentir convenablement préparés pour se confronter avec des situations pareilles, cette recherche, centrée sur cette problématique, a chosi comme objectif planifier, mettre en marche et analyser un programme d intervention pédagogique dans une école régulière de la ville de Natal/RN, auprès de quatre enseignants de l école fondamentale (7e Série) qui avaient reçu, dans leur classe, deux élèves atteints de paralysie cérébrale. S utilisant comme recours méthodologique de la recherche-action, le programme d intervention s est structuré autour de troix axes thématiques : l attitudinal, le pédagogique et le vécu en milieu scolaire, sous la forme de discussions théoriques et la mise en oeuvre de ces thématiques. Les données qui devraient être soumises à l analyse ont été collectées à partir des procédés d observation, d entretiens avant et après l intervention, du régistre de photos et d un questionnaire. Les interprétations faites, basées dans la comparaison du discours des sujets ont signalé que les enseignants ont progressé dans la maîtrise des savoirs scienfiques concernant la paralysie cérébrale et dans la connaissance des personnes atteintes par cette déficience. Par rapport aux valeurs et significations attribuées par les enseignants à ce programme d intervention à partir de leur choix des photos dans l ensemble du déroulement de ce processus formatif, elles s expriment par une prise de conscience très marquée, de la part des enseignants, par rapport :aux besoins éducatifs des élèves atteints de paralysie cérébrale ; à l importance et au vrai rôle que l école doit jouer face aux politiques d éducation inclusive ; aux difficultés vécues par ces personnes, qui réclament le plus profond respect de leurs ingularités ; la reconstruction d une nouvelle image concernant ces personnes ; la constatation qu il est possible aux enseignants d adapter et même de créer à l école des ressources et matériaux pédagogiques envisageant la qualité du processus d enseignement et apprentissage de l élève atteint de paralysie cérébrale ; finalement, la perception de l importance du travail en équipe, d un milieu scolaire accessible à ces personnes et de l appuis de la famille dans le contexte de l éducation inclusive. Les résultats obtenus, issus de ce programme d intervention, d après l évaluation finale des sujets, de part de témoigner de son efficacité, montrent que l intervention a été une excellente opportunité d habiliter ces enseignants et d améliorer le processus d enseignement à l école choisie comme le locus de cette recherche

Um Estudo de Politicas e Práticas do uso do GNV no transporte público urbano do Brasil

The use of Natural Gas Vehicle has had a fast increase lately. However, in order to have a continuous success this Program needs to develop converting devices of Otto-cycle engines, gasoline or alcohol, to the use of NGV (Natural Gas Vehicle) that presents low cost, maintaining the same original development of the vehicle and low level of emissions, considering the PROCONVE rules. Due to the need to diversify the matrix in order to avoid energetic dependence and due to strict pollution control, it has increased in the Brazilian market the number of vehicles converted to the use of NGV. The recent regulation of the PROCONVE, determining that the converted engines with kits should be submitted to emission testing, comes to reinforce the necessity of the proposed development. Therefore, if we can obtain kits with the characteristics already described, we can reach a major trust in the market and obtain an increase acceptance of the vehicle conversion for NGV. The use of natural gas as vehicle fuel presents several advantages in relation to liquid fuels. It is a vehicle fuel with fewer indexes of emissions when compared to diesel; their combustion gases are less harmful, with a major level of safety than liquid fuels and the market price is quite competitive. The preoccupation that emerges, and the motivation of this project, is to know which are the main justifications for such technology, well accepted in other countries, with a low index or emission, with a high level of safety, where its maintenance becomes low, reminding that for this it is necessary that this technology has to be used properly, and once available in the market will not motivate interest in the urban transportation companies in Brazil, in research centers in general. Therefore this project exists to show the society in a general way the current vision of the main governmental factors, of the national research centers and of the private companies concerning the use of natural gas vehicles in urban transport vehicles, in order to give a major reliability to the population as well as to motivate national market competitiveness with a low cost and reliable product and to enrich the national technology

Sistema web didático para a supervisão de redes fieldbus

Technological evolution of industrial automation systems has been guided by the dillema between flexibilization and confiability on the integration between devices and control supervisory systems. However, there are few supervisory systems whose attributions can also comprehend the teaching of the communication process that happens behind this technological integration, where those which are available are little flexible about accessibility and reach of patterns. On this context, we present the first module of a didactic supervisory system, accessible through Web, applied on the teaching of the main fieldbus protocols. The application owns a module that automatically discovers the network topology being used and allows students and professionals of automation to obtain a more practical knowledgment by exchanging messages with a PLC, allowing those who are involved to know with more details the communication process of an automation supervisory system. By the fact of being available through Web, the system will allow a remote access to the PLC, comprehending a larger number of users. This first module is focused on the Modbus protocol (TCP and RTU/ASCII)

Estudo da Potencialidade da produção de tijolos de adobe misturado com outros materiais: uma alternativa de baixo custo para a construção civil

The production of the red pottery brick, made traditionally with clay, is a technique that is already stabled. However, in spite of the little complexity that involves the conventional process of these bricks production, it are exposed to many problems that begin in the fase of exploration of the mines, the problems get worse because of the lack of the clay's characterization, and they continue through the steps of the dough preparation, conformation of the products, the drying and the burning process. The wastefulness is shown and so is the low quality of the material produced. Among other factors, the high use of energy in the burning makes the cost of this material inaccessible to the low income consumer. Besides this, the destruction of the environment around the mines and the use of native vegetation to produce wood - the most used fuel in the pottery industry - make serious environmental damage. The production technique of a new type of simple brick (adobe), that has low cost and no environmental damage, can be the viable altemative to lower the cost of this part of the civil construction, and, consequently, in the building of cheaper houses. In this paper, the results of the mechanical resistance of the adobe brick are shown, using in its composition, clay, natural vegetable fibers, cement and plaster in a process that is completely handcrafted and manual. It is intented to make clear that are possible alternatives to be put in practice, with the simple process, using "raw earth" that has been used in the construction of houses in thousands of years, trying to solve these severe problems. Analysis and tests were performed to find results that could prove the possibility of the utilization of this kind of material. Other studies are in progress, and the new researches are necessary to enrich this work, but it stays the certainty that there is potential to produce bricks from adobe, as an alternative that has low cost to civil construction

Desinfecção solar de água para comunidades de baixa renda

The use of solar energy for water disinfection, and is accessible to disadvantaged communities because of its low cost, has the advantage of using disposable materials such as bottles of polyethylene terephthalate (PET). We present a study that used two methods of disinfection: the methodology proposed by the project Solar Water Disinfection (SODIS), which consisted of water disinfection by solar radiation and temperature and the methodology which the temperature of the water for disinfection. In both, we seek to eliminate microorganisms that cause serious diseases such as dysentery, typhoid, cholera, etc. Water samples were collected in the community of Bass, where the population has low income and the incidence of waterborne diseases is high. The experiments were divided into two stages. In step 1 we studied the feasibility of disinfection and in step 2 the feasibility of the pilot plant to obtain adequate levels of disinfection temperatures desired. The results showed the efficiency of the disinfection process, reaching an average of 80 to 100% death of microorganisms, but regrowth was observed in some samples. Finally on the good results of stage 1, is designed and built and tested in an experimental pilot plant, which has shown to be feasible to promote water disinfection through the use of solar energy. The water after treatment is in accordance with the limits established by Brazilian legislation for clean water, maintaining a positive performance for the disinfection and acceptable levels of bacterial regrowth
