This paper aims at studying how circular dance can afford to sight-disabled peoples movement and how they can learn to cope with the deep movement of relation, consciousness, appropriation and communion with the world. Inside circular dance, a cosmic metaphor, is inscribed the movement of the world, which tells and changes amorously the human history. In the works of Paulo Freire and Maurice Merleau-Ponty one can find the necessary support to discuss, as long as possible, movement and existence. Research-action is used as a methodological approach whose empirical center is placed on the Institute of Education and Rehabilitation of Blind, in Natal, which shelters eight sightdisabled adults. The research s data reveal that the practice of circular dance concurs to enlarge the movement of the research s subjects, to develop a more accurate perception of their selves and of their own capacities, as well as improve the relations Me/Others, Me/World, which require a context of differences. The study has revealed that the practice of dance develops a better perception of the limits and surpasses as a human condition and, in consequence, the discovery of one s own body and the other s body as a resource of lessons and representations of the self and of the world. It lets out the development of a new way of thinking and coping with discrimination surrounding the disabled persons. In movement, in circular dance, the barrier between sight disablement and vision loses force.

Vitamin A is important in many essential body processes and its deficiency results in serious consequences for human health. Breast milk is the only source of this vitamin for children that are exclusively breastfed. Analysis of vitamin A in mother s milk is important because its concentration is related to maternal vitamin A status and to its ingestion by the mother during pregnancy. The aim of the present study was to assess the effect of maternal supplementation with retynil palmitate on the concentration of colostrum retinol under fasting and postprandial conditions. A total of 149 nursing mothers were recruited at the Januário Cicco Maternity School (Natal, Brazil) and allocated to two groups: Comparison (n = 69) and Test (n = 80). Blood and colostrum (in fasting and postprandial conditions) samples were collected up to 24hs after delivery. Serum retinol and colostrum levels were analyzed by high-performance liquid chromatography. The serum retinol level of 41.6 ± 12.7μg/dL (mean ± standard deviation) indicates adequate biochemical nutritional status. Colostrum retinol level was not influenced by serum retinol levels under any of the conditions established. In the colostrum, the retinol concentration in the unsupplemented test group was 67.3 ± 37.7 μg/dL under fasting and 80.3 ± 35.1 μg/dL under postprandial conditions (p<0.05), showing an increase of 19.3%. In the supplemented test group the values were 102.6 ± 57.3 μg/dL and 133.4 ± 78.3 μg/dL under fasting and postprandial, respectively (p<0.05), representing an increase of 30%. Considering that under fasting conditions most of the vitamin A transported to the milk originates in the retinol binding protein (RBP), the postprandial increase in colostrum retinol suggests a different transport mechanism of retinol to maternal milk from that performed by RBP. This situation becomes more evident under supplementation conditions.

Mothers with good vitamin A nutritional status during gestation and lactation are better able to nourish and protect their infant with maternal milk. Our hypothesis is that women with more serum retinol have more retinol and secretory immunoglobulin A in colostrum. 190 healthy puerperal women from a Brazilian public maternity were recruited and divided according to the cutoff point for serum retinol (30 μg/dL). A number of the women was supplemented with 200000 UI (60 mg) of retinyl palmitate in the immediate postpartum. Serum and colostrum were collected on the 1st day postpartum and colostrum again on the following day. Retinol (serum and colostrum) was analyzed by HPLC and SIgA (colostrum) by turbidimetry. The mothers presented with adequate biochemical indicators of nutritional status, according to serum retinol (44.6 μg/dL). There were significant differences (p= 0.0017 and p= 0.043, respectively) in retinol and SIgA levels in the colostrum of mothers with serum retinol > 30 μg/dL and < 30 μg/dL. The concentration of SIgA in the colostrum of non-supplemented mothers on the 1st day postpartum was 822.6 mg/dL, decreasing after 24 hours to 343.7 mg/dL. Supplemented mothers showed levels of SIgA in colostrum of 498.9 mg/dL on the 2nd day postpartum (p= 0.00006). The colostrum of women with good vitamin A nutritional status had more retinol and SIgA. Additionally, maternal supplementation increases the levels of SIgA in colostrum. The higher levels of SIgA on the 1st day postpartum showed the importance of early breastfeeding, given that it provides considerable immunological benefits to newborn infants

Vitamins A and E are essential nutrients in many biological processes, so that their adequate supply to the neonate is crucial. However, the bioavailability of vitamins may be limited by factors such as maternal nutritional status and the interaction between nutrients. This study aimed to investigate the effect of biochemical nutritional status of retinol and alpha-tocopherol levels in serum and colostrum. The study included 103 healthy puerperal women treated at the reference state maternity hospital (Natal-RN). Colostrum and serum samples were collected fasting in the immediate postpartum period and the analysis of retinol and alpha-tocopherol were determined by high-performance liquid chromatography. Specific cutoff points were adopted to characterize the biochemical status of vitamins A and E. For the total group of lactanting women the average concentration of retinol in serum (1.49 ± 0.4 μmol/L-1) and colostrum (2.18 ± 0.8 μmol/L-1), as well as alpha-tocopherol in serum (26.4 ± 8.0 μmol/L-1) and colostrum (26.1 ± 12.8 μmol/L-1), indicated adequate biochemical state. However, when evaluating the individual, was found a high prevalence of deficient serum (15%) and colostrum retinol (50%), and also alphatocopherol in serum (16%) and colostrum (61%). In women with serum retinol ≥ 1.05 μmol/L-1, found an inverse correlation between serum retinol and alpha-tocopherol in colostrum (p = 0.008, r = -0.28). This association was not observed in women with serum retinol <1.05 μmol/L-1. This situation demonstrates for the first time in humans that high physiological levels of serum retinol, without supplementation, can negatively influence the transfer of alpha-tocopherol in breast milk. Although the diagnosis of satisfactory nutritional status lactanting women showed high risk of subclinical deficiency of vitamins A and E from measurements made in the colostrum

O objetivo deste trabalho foi avaliar o efeito da interação da deficiência hídrica e da toxicidade do alumínio no crescimento inicial e teores de prolina livre em duas cultivares de guandu, IAPAR 43-Aratã e IAC Fava Larga, cultivadas em hidroponia. As plântulas foram submetidas aos estresses em solução nutritiva (pH 3,8), nos potenciais osmóticos de 0, -0,004, -0,006, -0,008 e -0,010 MPa, com 0, 0,25, 0,50, 0,75 e 1 mmol dm-3 de Al3+. O experimento foi conduzido em sala de crescimento, sob luminária com irradiância média de 190 mmol m-2 s-1 , fotoperíodo de 12 horas e temperatura de 25+1ºC. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 2x5x5 (duas cultivares de guandu, cinco potenciais osmóticos e cinco níveis de alumínio), com quatro repetições. Os dados foram submetidos às análises de regressão polinomial, agrupamento e componentes principais. A deficiência hídrica causa redução do crescimento da parte aérea do guandu, e a toxicidade do alumínio provoca diminuição do crescimento radicular. Houve aumento nos teores de prolina livre nas duas cultivares sob deficiência hídrica, e apenas na IAC Fava Larga sob toxicidade de alumínio. Na análise multivariada, foi observada alta correlação no crescimento e no acúmulo de prolina na cultivar IAC Fava Larga, o que evidencia provável tolerância aos estresses associados.

Sugarcane is a very important economic crop in Brazil. The effects of abiotic stresses cause negative reduction of the productivity in the sugarcane industry. In order to identify indicators of stresses tolerance, two physiological variables were evaluated, nitrate reductase activity and chlorophyll contents in young plants of sugarcane, cv. IAC91-5155. The simultaneous effect of abiotic stresses of high occurrence in Brazilian soils are, water deficiency and aluminum toxicity. The plants were submitted to three treatments of water availability (% field capacity, FC): no stress (70% FC), moderate stress (55% FC), and extreme stress (40% FC); and three acidity treatments in the soil (base saturation, V%): no acidity (V=55%), average acidity (V=33%), and high acidity (V=23%). The experiment was carried out in greenhouse, with 29.7 +/- 4.3 degrees C and 75 +/- 10% RH. The experimental design was in randomized blocks, in 3x3 factorial arrangement, with four replicates. After 60 days, nitrate reductase activity and chlorophyll contents were evaluated in the diagnostic leaf. The results demonstrate that the response of plants to a combination of drought and aluminum toxicity, similar to the conditions in many natural environments, is different from the response of plants to each of these stresses applied individually, as typically tested in the laboratory. The nitrate reductase activity can be used as a biochemical-physiological marker of water deficiency while chlorophyll contents can be used as a biochemical-physiological marker of both of them, water deficiency or aluminum toxicity in soil. Both parameters can not be as a biochemical-physiological marker for acclimation of young plants of sugarcane cv. IAC91-5155, under the combined stresses.

With a focus on the need for effectiveness of fundamental rights of persons with disabilities, this dissertation held a scientific research to analyze the degree of implementation of reservation of positions and public jobs to people with disabilities in the Brazilian State, because the 1988 Federal Constitution expressly determined such a reservation in your article 37, VIII. Highlight that this subject is enough evidence, given the large number of open public competition in recent years in Brazil, as well as recent proposals to grant equal rights to blacks (Bill nº 6,738/2013). In addition, the wording the constitutional device comes fomenting heated discussions on the subject, which are flowing on the doors of the judiciary and are spicy because such protection Microsystem vulnerable group has several gaps in the regulation of this policy. However, the research produced, unlike other related theme, does not address the problem of inefficiency in its constitutional theory, that is, abstractly, but also focuses on a specific analysis of this ineffectiveness within Brazilian society, so that research based on a bibliographical analysis, plus a study case law, at the national level, as well as in field research, while case study, focusing on the technique of the analysis of everyday life, because it was believed that the degree of realization of the constitutional norm debated is not yet a satisfactory degree of effectiveness. Soon, the methodological procedures chosen confirmed such a hypothesis and contributed to the study of realization of the fundamental right to work of people with disabilities in Brazil, the light of a Constitutional State, proposing a constitutionally appropriate model the greater effectiveness of the constitutional norm studied

La défense d une école inclusive dans les forums internationaux du monde entier a stimulé l adoption de politiques éducationnelles d inclusion et la pratique d inclusion dans les écoles, de sorte à ce que la scolarisation des élèves aux besoins éducatifs spéciaux dans les classes comunes est devenue une réalité dans la majorité des systèmes d éducation. Et pourtant, l inclusion scolaire, au Brésil, avance à pas lents et pose d innombrables questions, notamment quand il s agit de l inclusion des personnes qui présentent une déficience mentale dans les niveaux d enseignement plus avancés. Basé sur ce fait, et tout en considérant que les études et recherches sur ce thème, au Brésil, sont centrées majoritairement sur l éducation enfantine et les séries initiales de l enseignement fondamental, cette étude se propose d analyser l inclusion d une élève ayant une déficience mentale, inscrite dans l Enseignement Moyen, dans une école appartenant au réseau d enseignement de l Etat, dans la ville de Natal RN. Pour répondre aux questions proposées dans cette étude nous avons fait appel aux méthodologies qualitatives, du genre Etude de Cas, et au cours de saalisation avons utilisé l interview demi-structurée et l observation libre dans l ambiance naturelle de l école. Ont participé de l étude, en plus de l élève qui présentait une déficience mentale, sa mère et deux segments de l école, desquels ont fait partie trois professionnels de l équipe administrative pédagogique et quatre enseignants. L analyse des données a mis en relief la résistence de l école à répondre au projet pédagogique d éducation inclusive, aspect qui a un rapport très étroit avec les spécificités de l Enseignement Moyen, la structure traditionnelle d un enseignement basé sur l idée d une classe homogène, et le bas niveau d attentes des éducateurs concernant les possibilités d apprentissage et de développement de l élève handicapée mentale. De surcroît, le manque de directives pour conduire les adaptations pédagogiques et du curriculum à l école ont rendu fragile l action des enseignants, dont le résultat est une pratique d intégration rudement malmenée. Au travers des points de refléxions suscités par cette étude, nous considérons que l inclusion des élèves qui présentent une déficience mentale doit être centrée sur une pratique pédagogique qui repousse l idée de soumettre tous les élèves à des procédures universelles cristalisées sur des pratiques imposées par les contraintes d homogénéisation, et qui, contrairement, puisse trouver à l école des conditions favorables au développement de chacun, au travers des processus d apprentissages formés par des instances de médiation et d interaction sociales

A partir des deux dernières décénnies, des changements importants ont touché l éducation des personnes aux besoins éducatifs spéciaux. On est dans une quête permanente de leur inclusion dans les différents niveaux de l enseignement régulier. De ce fait, les institutions éducationnelles se confrontent avec le défi du changement, devant s adapter de plus en plus aux besoins de ces élèves et devenir plus récptives à l égard de tous. Malgré la lenteur de ce changement, cela favorise beaucoup l accès des élèves à des niveaux d enseignement que jamais on aurait supposés, tels que l enseignement supérieur. C est bien dans ce contexte qu au cours de l année 2002 des étudiants handicapés visuels ont accédé aux formations de Philosophie, Economie et Sciences Sociales de l Université Fédérale do Rio Grande do Norte. Cela nous a motivé à conduire une analyse, au cours de 2003, pour connaître de plus près ce processus d inclusion universitaires de trois étudiants handicapés visuels. Comme méthode nous avons utilisé l étude de cas, et l entretien comme instrument de collecte des données. Après l analyse, les résultats montrent bien que l inclusion a permis à ces étudiants de surmonter un tas de barrières, telles que l examen d accès à l Université (Vestibular), outre la chance de se socialiser et d être bénéficiaires d expériences qui, suscités dans un milieu universitaire, vont au-dede l univers académique. Les collègues de ces étudiants, auprès desquels ils convivent, eux-aussi ont été les bénéficiaires, du fait qu ils ont eu l opportunité d apprendre ensemble les uns avec les autres, tout en respectant leur limitations et potentialités, mais en les appuyant et en les stimulant de mieux en mieux. Il faut reconnaître que plusieurs actions au sein de l Université envisageant l accès et la permanence de ces étudiants ont été couronnées de succès, mais force est de dire qu il y a aussi beaucoup de choses à faire en ce qui concerne : la préparation du corps enseignant et des fonctionnaires ; l orientation de la communauté plus élargie ; la chute des barrières pédagogiques et attitudinales, et surtout l appui humain et matériel indispensables au plein développement de ces étudiants

Inclusion of students with disabilities is a recent case that has been discussed in school contexts, but the current policy of inclusion for access and retention of students in higher education is still a problem face there is much to do, therefore, are incipient studies in which this student body is involved. Accordingly, what is happening is that the most studies deal with on these students and little is said about them. For inclusive education thus the institution should prepare to receive students, having as one of its premises their point of views about what actually experience aiming at promoting education for all. Therefore, this study deals with the process of inclusion of students with disabilities regularly enrolled in undergraduate courses at the Universidade Federal do Rio Grande do Norte - UFRN.They were used the assumptions of qualitative research enabled by the case study method and semi-structured interviews. It has been analyzed by guiding actions and teaching practices, under the views of disabled students and teachers, the conditions of access and permanence offered by UFRN. Twelve students with physical, visual, hearing disabilities participated and five teachers from the acedemic centers that in academic year 2008 taught to these students. For data analysis it was used the technique of content analysis. It was extracted two themes: access and retention of students with disabilities in UFRN, in which emerged the categories described and analyzed in the course of this work. The results show the difficulties of access and retention of students with disabilities within the UFRN, such as attitudinal, pedagogical and architectural barriers. However, as it has also turned out, initial advances in the quest for achieving more effective actions to guarantee access and permanence of these students in UFRN. It has concluded that the scope for the exercise of citizenship in the pupils with disabilities who need this Higher Education Institution has an inclusive education Project, wide and consolidated, for the actions undertaken by the Ministry of Education - MEC, by itself, are not guaranteed to all students due to mobility, autonomy and security. It has hoped this work will bring benefits for new studies to develop features that were located, but were not our focus, because then the UFRN may advance the inclusive process of disabled students

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

A mid the many transformations and advances that the contemporary society is going through, the right to education is a topic that does not end and becomes increasingly present, given the urgency of including students with disabilities in education. Given this new reality, schools are challenged to receive them with quality, and implement actions that promote favorable conditions for their development at school. Accordingly, it is fundamental the organizational restructuring of education to meet the specific needs of students. Thus, it is imperative that educational institutions defining the type of person who intend to form and the society proposing to build. These are aspects that precede any question, since the knowledge covered in the curriculum will contribute directly to the creation of human beings are involved there. Based on this theme, this assignment reports aspects of a survey of a local public school, located in Natal/RN, which deals with the analysis of the curriculum and its implementation in teaching practice in the classroom, before the inclusion of students with disabilities intellectual. Thus, to undertake a study of case with five professionals at school, involving documentary analysis and observation of the curriculum of the pedagogical practice of teachers in the classroom, as well as conducting an interview with all stakeholders. To this end, the data analyzed shows that, although the right of citizens with disabilities is guaranteed by constitutional law, the school, locus of this study, have not realized the extent of conquest. Does not recognize the fact of being in school and learn together with others is also a right of persons with disabilities. Thus, while your resume is to present a progressive vision, believed to be open, concerned with the selection and organization of content, with flexibility in defining the goals, with the search for diversification of the procedures adopted, as well as the planning activities teaching and learning based on the level of student learning, this is not effective in teaching practice, either through ignorance of the guidelines defined either by lack of knowledge about the proposal and an inclusive curriculum can provide answers to all educational students, including those with intellectual disability
