The first chapter introduces the legal concept of disabled people and their types in order to provide a better understanding of who can be considered. It also deals with the role played by the State, society and family in relation to the treatment they are given to the disabled and their role in defending their interests. The second chapter is devoted to accessibility and fundamental rights for people with disabilities, given that accessibility is the gateway to freedom and autonomy for the enjoyment of a dignified and egalitarian life. The third chapter presents the concept of the Third Sector and the way in which it has been developing its activities in the provision of the public services that it performs, whose social function has been important for the target public. In the fourth chapter, a study directed to the assistance that the Third Sector has been rendering to the visually impaired person has been carried out, in the supporting role that it exercises in relation to the State. In addition to the legal research, a case study was conducted, with a questionnaire applied to the visually impaired who presented their demands and their perception regarding the Third Sector. Then the final considerations. / A presente disserta????o analisa como as atua????es advindas das organiza????es do Terceiro Setor s??o importantes para proporcionar acessibilidade ?? pessoa com defici??ncia visual no que diz respeito aos direitos que lhes s??o fundamentais.

The question that guides the problem is: which are the effects of schooling in the production of subjectivity in students with disabilities? The general objective is to understand the effects of the schooling process in the production of subjectivity of subjects with disabilities; two specific objectives were established by the author, one is to investigate the effects of the school trajectory in the production of subjective senses in these subjects, the other is to seek indicators of subjective senses built during the schooling process. The theoretical framework that supports this work used authors who understand the development of subjects from their sociocultural context, the category of disability and senses presented by Vigotsky, and the works on the production of subjectivity of Fernando Gonz?lez Rey. The investigation and collection of data took place in a private school, which has from the Preschool up to High School, in the city of Porto Alegre, Rio Grande do Sul, through analysis of documents and semi-structured interviews conducted with three students who are diagnosed with physical and/or intellectual disability and that are attending High School, as well as with their mothers. This study has a qualitative approach, with a descriptive character, that uses the semi-structured interview as instrument of data collection. From the viewpoint of data analysis, it was used the Discursive Textual Analysis (MORAES, 2011) which, in qualitative research, expects the immersion of the researcher in the documentary corpus, from which categories emerge from the research subjects' impressions. As for the findings of the study, it is concluded that the effects of the schooling process in the production of subjectivity in subjects with disabilities are unique, although permeated by social subjectivity, so that each subject produces a different sense and this sense is linked to the context in which the subject is inserted, in its trajectory that also produced meanings and that serves as the basis for new subjective senses. It is inferred that, within the scope of the social expectations that the school attends, the subjective senses produced are linked to the feeling of exclusion, and this occurs because schooling practices are still based on processes and methodologies that aim at the homogeneity of the subjects which, as a general rule, prevents teachers and collaborators from seeing the subjective processes of the students. This new attitude inevitably passes through teachers, since these are the very representation of schooling for students. / Este estudo tem como tema os efeitos da escolariza??o na produ??o da subjetividade dos sujeitos com defici?ncia. A pergunta que norteia o problema ?: quais os efeitos da escolariza??o na produ??o da subjetividade em alunos com defici?ncia? O objetivo geral ? compreender os efeitos do processo de escolariza??o na produ??o da subjetividade de sujeitos com defici?ncia; foram estabelecidos, pela autora, dois objetivos espec?ficos que s?o investigar os efeitos da trajet?ria escolar na produ??o de sentidos subjetivos nestes sujeitos, e tamb?m buscar indicadores de sentidos subjetivos constru?dos durante o processo de escolariza??o. Como marco te?rico que sustenta este trabalho foram utilizados autores que compreendem o desenvolvimento dos sujeitos a partir de seu contexto sociocultural, a partir da categoria de defici?ncia e de sentidos, apresentada por Vigotsky, e dos trabalhos sobre a produ??o da subjetividade de Fernando Gonz?lez Rey. A investiga??o e coleta de dados ocorreram em uma Escola da rede privada, que atende do Maternal ao Ensino M?dio, na cidade de Porto Alegre, no Rio Grande do Sul, por meio de an?lise de documentos e entrevistas semiestruturadas realizadas com tr?s alunos que t?m diagn?stico de defici?ncia f?sica e/ou intelectual e que cursam o Ensino M?dio, bem como com suas genitoras. Este estudo tem uma abordagem qualitativa, de car?ter descritivo, que utiliza a entrevista semiestruturada como instrumento de coleta de dados. Do ponto de vista da an?lise dos dados, utilizou-se a An?lise Textual Discursiva (MORAES, 2011), que, nas pesquisas qualitativas, prev? a imers?o do pesquisador no corpus documental, de onde emergem categorias a partir das impress?es dos sujeitos da pesquisa. Quanto aos achados do estudo conclui-se que os efeitos do processo de escolariza??o na produ??o da subjetividade em sujeitos com defici?ncia s?o singulares, embora permeados pela subjetividade social, de forma que cada sujeito produz um significado diferente e este est? vinculado ao contexto em que o sujeito est? inserido, na sua trajet?ria que tamb?m produziu significados e que serve de base para novos sentidos subjetivos. Infere-se que, no ?mbito dos anseios sociais que a escola atende, os sentidos subjetivos produzidos est?o vinculados ao sentimento de exclus?o, e isto ocorre em raz?o das pr?ticas de escolariza??o ainda estarem pautadas em processos e metodologias que visam ? homogeneidade dos sujeitos, o que, via de regra, impede que os professores e colaboradores enxerguem os processos subjetivos dos alunos. Essa nova postura passa inevitavelmente pelos professores, j? que estes s?o para os alunos a pr?pria representa??o da escolariza??o.

Under the effect of a - 15 atm stress (using mannitol as osmoticum), Centralmex showed the highest percent germination while IPEACS III showed the lowest. The germination of Piran?o seeds fell in between. There also differences in root and coleoptile growths of the three varieties as compared to that of the controls (germinated in demineralized water). At a more advanced stage of grouth (6-8 leaves, plants in pots kept in a greenhouse), the soil-water stress affected the plants differently. IPEACS III continued to be severely affected but Piran?o was now the least affected, with Centralmex falling in between. The effects of water stress upon the plant metabolic patterns resulted in a increase in the leaf content of nitrate-N, free amino-N, ammonia-N, free proline and soluble sugars.181 There was on the other hand a reduction in nitrate reductase activity and protein content. Although the same general metabolic pattern was observed for the three varieties, significant differences could be detected among the varieties. These results indicated that the greenhouse environment was adequate for the study of plant responses to water stress, even enabling the distinction between varietal differences. The content of free amino-N and soluble sugars in the plant leaves showed a higher sensitivity to moderate water stress than the other indicators. A special attention was given to the study of the increase in free proline levels in the leaves. The ellucidation of the factors governing the relative accumulation of this metabolite in corn leaves requires more detailed studies. Only then could proline content be considered a safe indicator of water stress resistance for corn plants. The plants under water stress were also submitted to growth analysis. This test was very efficient for the study of dry weight and leaf expansion variation among varieties. The results of this study shows that three main factors are responsible for the plant resistance to water stress, namely: a. Tolerance to dehydration (differences in R.W.C.) b. resistance to loss in protein (differences in protein-N levels and free-N/protein-N ratios)182 c. increasc in root/shoot ratios. The present study shows the necessity of experiments with field grown plants, to check the sensitivity of the various factors studied and to compare the behavior of different corn varieties in the field with that in greenhouse. / Tr?s variedades de milho (Zea mays L.), Piran?o, Centralmex e IPEACS III, foram submetidas a stress h?drico em duas fases do crescimento vegetativo. As diferen?as na taxa e percentagem final de germina- ??o, alongamento da raiz e do cole?ptilo foram avaliadas nas tr?s variedades, quando submetidos a um stress osm?tico de -15 atmosferas, usando-se manitol como osmoticum. Centralmex mostrou a maior percentagem de germina??o final nestas candi- ??es e IPEACS III, a menor; Piran?o apresentou um comportamento intermedi?rio. Diferen?as entre as variedades nos respectivos percentuais de alongamento da raiz e cole?ptilo foram notadas ao serem comparadas com seus controles mantidos em ?gua deionizada. Quando as variedades foram comparadas em um est?gio mais avan?ado de crescimento (6-8 folhas), e o stress h?drico induzido por desseca??o progressiva do solo, em casa de vegeta??o, a variedade IPEACS III mostrou-se severamente afetada,Piran?o, relativamente, a menos afetada, apresentando Centralmex um comportamento intermedi?rio. Neste ?ltimo est?gio de crescimento, fez- se uma compara??o da sensibilidade de distintos indicadores metab?licos ? defici?ncia h?drica. Com rela??o ao metabolismo de N, foram avaliados os teores foliares de N-n?trico, N-amoniacal, N-amino livre, prolina e N-proteico. No que diz respeito ao metabolismo de carbohidratos, avaliou-se o teor foliar de carbohidratos sol?veis. Foram observados incrementos nos teores de N-amoniacal, N-n?- trico, N-amino livre, prolina e carbohidratos sol?veis. Concomitantemente, observou-se decr?scimos para o teor de N-proteico e a atividade de nitrato-reductase. Este padr?o geral de varia??o, em resposta a stress h?drico, se expressou em forma diferencial (estatisticamente significativa) entre variedades, indicando que, o ambiente proporcionado pela casa de vegeta??o foi apropriado para a separa??o dos efeitos decorrentes do stress h?drico daqueles devidos ?s caracter?sticas varietais. Os teores de N-amino livre e carbohidrato sol?vel mostraram uma maior sensibilidade a deficits h?dricos moderados. Em adi??o aos indicadores metab?licos, realizou-se a an?lise de crescimento, que mostrou ser um procedimento apropriado para descrever as varia??es em taxas de acumula??o de mat?ria seca e expans?o de ?rea foliar entre as variedades. Os dados sugeriram que, as diferen?as observadas em resist?ncia ao stress h?drico entre as variedades podem ser decorrentes de tr?s tipos de efeitos: toler?ncia ? desidrata ??o (diferen?as em C.H.R.), toler?ncia a perda de prote?nas (diferen?as nos teores de N-proteico e na rela??o N-sol?vel/ N-proteico) e incrementos na rela??o raiz/parte a?rea. A evolu??o do teor foliar de prolina foi particularmente observada nos tr?s cultivares, visando-se ligar o seu teor ? explica??o das diferen?as em sensibilidade (ou resist?ncia) ao stress h?drico. Os resultados atualmente obtidos, mostraram que, pelo menos em milho, ? necess?rio um estudo mais detido dos fatores que governam a acumula??o deste metab?lito, antes de aplicar-se indiscriminadamente este par?metro como indicador de resist?ncia ? seca. Finalmente, foi destacada a necessidade de experimenta??o direta no campo, visando a determina??o do grau de sensibilidade dos distintos indicadores e a quantifica??o das diferen?as com respeito ao comportamento das variedades em casa de vegeta??o.

Em uma abordagem inclusiva, tais alunos(as) inseridos(as) em escolas regulares demandam modifica??es e reordenamentos did?tico-pedag?gicos e atitudinais. Assim, a investiga??o proposta nesta disserta??o procurou compreender, a partir das hist?rias de vida e escolar de jovens com DI, como suas trajet?rias escolares reverberaram na autoimagem, considerando a rela??o entre a interface estigma, identidade e DI. O estudo teve como objetivo analisar como as experi?ncias escolares de jovens com DI interferem na forma??o da sua identidade. Participaram da investiga??o tr?s jovens com diagn?stico de DI e suas respectivas tias/m?es. A metodologia empregada seguiu a abordagem qualitativa, norteada pelo m?todo de hist?ria oral de vida. Na constru??o de dados, foi utilizada a entrevista recorrente, o que permitiu apreender os sentidos atribu?dos ? vida escolar pelos sujeitos da pesquisa. Organizamos as categorias da seguinte forma: a) trajet?rias escolares e de vida; b) concep??es de si e experi?ncias de socializa??o na escola regular; c) processos de escolariza??o na escola regular. A an?lise dos dados permitiu compreender os tipos de experi?ncias com o estigma que os estudantes com DI est?o vivenciando no contexto escolar, ampliando consideravelmente os conhecimentos acerca da maneira como o processo de inclus?o de pessoas com DI est? sendo realizado, seus avan?os e limita??es no que diz respeito ? garantia da socializa??o e escolariza??o na escola regular. Verificamos, com o estudo, que a escolariza??o de pessoas com DI inseridas em salas regulares, nos ?ltimos anos do Ensino Fundamental e no Ensino M?dio, ainda ? marcada pela precariza??o dos processos de inclus?o, pela n?o aceita??o e estabelecimento de contatos mistos n?o rec?procos, refor?ando o estigma da n?o aprendizagem e desenvolvimento dos(as) alunos(as) com DI, bem como a cren?a de que a escola regular n?o ? o lugar deles. Uma das li??es desta disserta??o ? a necessidade da cria??o de um ambiente escolar menos restritivo para os(as) alunos(as) com DI, possibilitando a constru??o das identidades sem limit?-las e condicion?-las a um suposto r?tulo, considerando a multiplicidade de atributos e potencialidades que devem ser efetivamente desenvolvidas no decurso da vida escolar, criando novos significados sobre o que ? defici?ncia intelectual no cotidiano escolar. / In the XXI century, despite the speech of especial education in an inclusion perspective, some processes of stigmatization and segregation are still present practices in brazilian school institutions, especially, when it comes to students with Intellectual Disability (ID). In an inclusive aproach, such students inserted in regular schools require modifications, some didactic-pedagogical and attitudinal rearrangements. Thus, the proposed research in this dissertation aims to understand from the life and school histories of young people with ID, how their school trajectories had reverberated in the self-image they establish of themselves, Considering the relationship between the stigma interface, identity and ID. The study aimed to analyze how the school experiences of young people with ID interfere in the formation of their identity. Three young women diagnosed with ID and their respective aunts / mothers had the participation in the study. The applied methodology follows a qualitative approach, guided by the method of oral history of life. In the data construction, the recurrent interview was used, which allowed the apprehension of meanings attributed to the school life by the subjects of the research. We organized the categories as follows: a) school and life trajectories; b) conceptions and experiences of socialization in the regular school; c) schooling processes in regular school. The data analysis allowed us to understand the types of experiences with the stigma which students with ID are experiencing in the school context, considerably broadening the knowledge about the way the process of including people with ID has been done, its advances and its limitations with regards to the guarantee of socialization and schooling in the regular school. We verified, with the study, that the schooling of ID people inserted in regular classes, in the last years elementary and high school, is still characterized by the precariousness of inclusion processes, through the non-acceptance and the establishment of a non-reciprocal mixed contacts, reinforcing the stigma of the non-learning and development of students with ID, as well as the belief that regular school is not their place. At last, one of the lessons (provided by this) dissertation is the need to create a less restrictive school environment for ID students, allowing the construction of identities without limiting and conditioning them to a supposed label, considering the multiplicity of attributes and potentialities that must be effectively developed in the course of a school life, creating new meanings about what is intellectual disability in a school routine.

The youths who enter in this educational system need proper education which would enable them to continue and succeed. Among these youths, there are those with visual impairments. In Brazil their participation in courses of higher education has increased more than 370% between the years 2003 and 2005. Given this scenario, we chose a qualitative approach to the current research that aims to examine and analyze the inclusion of blind students in private Graduate Schools in Federal District. The paper represents the perspective of these students. To achieve this it was necessary to check and analyze the resources provided by these institutions to keep and successfully graduate students with visual impairments. And also reports from these students, interviews with representatives of institutions and on-site observation. It makes a comparison between the needs presented by these students and the specific treatment offered by the respective institutions of higher education. The process of data collection was based on interviews made by the researcher with students with visual disabilities and representatives of institutions of higher education, in addition to reports done during the visit to the institutions. This research revealed that the complete fulfillment of the student???s rights with visual impairments by institutions of higher education will not be met until there is a civic education of students and the legal prerogative for the actions of the institutions. Students interviewed showed no heed to their rights and duties when enrolling in an undergraduate course, instead they have only ensured their presence in the chosen course and enjoyed what was offered. On the other hand the institutions, despite receiving students with special educational needs for at least five years, do not reveal the institutionalization of actions to ensure adequate care to these students. It is necessary to deconstruct the image of the ideal or stigmatized disability in the school community and then allow the generation of equal opportunity for these students besides ensuring the rights and duties common to all people. / A not??ria expans??o da educa????o superior no Brasil nas ??ltimas d??cadas trouxe consigo uma s??rie de contradi????es e dilemas. Os jovens que adentram nesse sistema de ensino requerem condi????es educacionais que contribuam para sua perman??ncia e ??xito. Dentre esses jovens, h?? aqueles com defici??ncia visual que s?? no Brasil aumentaram sua participa????o em cursos da educa????o superior em mais de 370%, entre os anos de 2003 e 2005. Diante desse cen??rio, optou-se por uma abordagem qualitativa para a atual pesquisa que visa discorrer e problematizar sobre a inclus??o de estudantes cegos em institui????es de ensino superior particulares do Distrito Federal a partir da perspectiva desses estudantes. Para alcan??ar tal objetivo se fez necess??rio verificar e analisar os recursos disponibilizados por essas institui????es para promo????o da perman??ncia e conclus??o exitosa dos estudantes com defici??ncia visual, contando com relatos dos pr??prios estudantes, entrevista de representantes das institui????es e observa????o in loco; e ent??o tecer compara????o entre as necessidades apresentadas por esses estudantes e o tratamento espec??fico oferecido pelas respectivas institui????es de ensino superior. O processo de coleta de dados foi baseado em entrevistas feitas pela pr??pria pesquisadora com os estudantes com defici??ncia visual e os representantes das institui????es de ensino superior, al??m das anota????es realizadas durante a visita ??s institui????es. Essa pesquisa revelou que o cumprimento pleno dos direitos dos estudantes com defici??ncia visual por parte das institui????es de ensino superior n??o se far?? enquanto n??o houver uma forma????o cidad?? dos estudantes e a prerrogativa legal para as a????es das institui????es. Os estudantes entrevistados mostraram n??o se atentarem para seus direitos e deveres ao ingressarem em um curso de gradua????o, apenas garantindo sua presen??a no curso escolhido e aproveitando o que lhe foi oferecido. J?? as institui????es, apesar de receberem estudantes com necessidades educacionais especiais h?? pelo menos 5 anos, n??o revelam institucionaliza????o de a????es que garantam um atendimento adequado a tais estudantes. Al??m disso, atentou-se que ?? necess??rio desconstruir a imagem ideal ou estigmatizada da defici??ncia diante de toda comunidade escolar para ent??o possibilitar a gera????o da isonomia de oportunidades e assegurar a esses estudantes os direitos e deveres comuns a todas as pessoas.

After the Second World War, the practice increased all around the world, especially for the recovery of the people who were disabled in the war, to aid rehabilitation back into society. Periodically scientific and technological developments changes elite and amateur sport. Improving the performances is the main reason for continual long and hard training; however, these training sessions can be monotonous, occasionally they need to be renewed in order to motivate the sportspeople. There is a huge communication difficulty in the swimming environment. The aim of this study was the development of a wireless communication system, which allows the haptic signaling between one coach, and many athletes who may be deaf and/or blind. This work has found a solution to overcome these hindrances, the VIBERSWIM. The system is comprised of a transmitter in a graphic touchscreen display, and receivers embedded and fitted to the swimsuit. Using wireless technology, the transmitter sends encoded commands, which has the capability of addressing individual or multiple receivers. A power driver and vibracall motors allows the receiver to transmit haptic signals to the swimmers and those signals have pre-determined specific meanings. The receiver has low energy consumption, 14 autonomy hours, works in aqueous environments and is able to emit audio commands. The prototype was tested and has the capability of transmitting signals over 100 meters. The innovative features of the VIBERSWIM has the potential to, radically, increase the communication between coaches and para-swimmers, in order to elevate the effectiveness of the training sessions. / Esporte adaptado ? praticado mundialmente h? centenas de anos. Ap?s a Segunda Guerra Mundial, essa pr?tica aumentou sobremaneira em muitas partes do mundo, principalmente para recuperar lesionados em combate e retorn?-los ao conv?cio social normal. O desenvolvimento tecnol?gico e cientifico acarreta constantemente mudan?as no esporte de alto-rendimento e, consequentemente, no esporte amador. A busca pela melhoria da performance ? o que motiva o mundo esportivo, ent?o, as longas jornadas de treinamento t?m que ser sempre renovadas. H? grande dificuldade de comunica??o no ambiente da nata??o, devido ao ambiente externo ruidoso e do pr?prio meio aqu?tico. De tal maneira que se buscou encontrar, neste trabalho, uma solu??o para melhorar a comunica??o entre o treinador e para-atletas de nata??o. Este trabalho teve como objetivo principal o desenvolvimento de um sistema de comunica??o e sinaliza??o t?til sem fio para utiliza??o entre um treinador e m?ltiplos para-atletas de nata??o com defici?ncia auditiva e/ou visual, o VIBERSWIM. O sistema consiste de um m?dulo transmissor em um display gr?fico com interface touchscreen (de posse do t?cnico) e m?dulos receptores encapsulados e adaptados ao uniforme de treinamento (de posse dos nadadores). Com a utiliza??o de tecnologia de redes sem fio, o transmissor envia comandos ao receptor, de forma codificada e com endere?amento ?nico. Devido a um conjunto de driver de pot?ncia e motores vibracall, o receptor gera sinais vibrat?rios ao corpo dos nadadores para-atletas e esses sinais t?m significados espec?ficos para a corre??o das t?cnicas de nado. O receptor possui baixo consumo, autonomia de 14h, pode trabalhar em ambientes subaqu?ticos e pode ser adaptado tamb?m para emiss?o de comandos de ?udio. O prot?tipo foi testado e funcionou, conforme as especifica??es estabelecidas, a mais de 100m, e devido as suas caracter?sticas t?cnicas inovadoras, este sistema apresenta grande potencial para o aux?lio em treinos de nata??o.

Thus, we investigate the technologies, with emphasis on Information and Communication Technologies (ICT), used by university students with visual impairment in their learning process in Higher Education in the city of Macap? / AP, with two blind students from Stadual University of Amapa (UEAP). We established as research objectives: To investigate the technologies used by university students with visual impairment in their learning process; To characterize the choices of pedagogical tools of these students in the scope of Information and Communication Technologies; Identify possible technological barriers in the learning process in Higher Education; Characterize the impacts of the technologies used by these students in their learning process. It is worth noting that in order to problematize the process of inclusion of students with visual impairment through the use of ICT as a dimension of accessibility to knowledge, the objectives were deployed in the following study questions: There are other tools of assistive technology in the daily life of the room of class?; What are its impacts on the learning process of students with visual impairment in Higher Education ?; What barriers or obstacles are evident in the process of schooling of students with visual impairment in Higher Education ?; What assistive technology tools are privileged in the choices of these visually impaired students in their learning process ?; What are the didacticpedagogical impacts of the technologies used in the learning process of students with visual impairment? Thus, this study contributes, adopting the methodological conception of Critical Theory as a method, with emphasis on Theodor Adorno's thought, for the unveiling of the plots experienced by students with visual deficiency in Public Higher Education of Amap?. For this, we use as a data collection procedure the semi-structured interview. In the progress of this study, we obtained as a result that even with the possibilities in the access to bibliographic collections in universities and academic databases, with all the tools available to students with visual impairment, either through braille, extended text or digital media , The subjects of our study still face numerous didactic-pedagogical barriers / Nesse estudo discutimos os aspectos pol?tico-legais que se voltam para o processo de inclus?o de estudantes com defici?ncia visual na Universidade, considerando-a como geradora de conhecimento e promotora da emancipa??o de seu corpo discente, reafirmando o direito de isonomia e equidade de oportunidades. Assim, investigamos as tecnologias, com ?nfase nas Tecnologias de Informa??o e Comunica??o (TIC), usadas por universit?rios com defici?ncia visual em seu processo de aprendizagem no Ensino Superior da cidade de Macap?/AP, tendo como interlocutores dois estudantes cegos da Universidade do Estado do Amap? (UEAP). Estabelecemos como objetivos da pesquisa: Investigar as tecnologias usadas por universit?rios com defici?ncia visual no seu processo de aprendizagem; Caracterizar as escolhas das ferramentas pedag?gicas destes estudantes no ?mbito das Tecnologias da Informa??o e Comunica??o; Identificar poss?veis barreiras tecnol?gicas no processo de aprendizagem no Ensino Superior; Caracterizar os impactos das tecnologias utilizadas por estes estudantes no seu processo de aprendizagem. Destaca-se que ao problematizar o processo de inclus?o de estudantes com defici?ncia visual por interm?dio do uso das TIC como mais uma dimens?o de acessibilidade ao conhecimento, os objetivos foram desdobrados nas seguintes quest?es de estudo: ?Existem outras ferramentas de tecnologia assistiva no cotidiano da sala de aula??; ?Quais os seus impactos no processo de aprendizagem de estudantes com defici?ncia visual no Ensino Superior??; ?Quais as barreiras ou obst?culos s?o evidenciados no processo de escolariza??o de estudantes com defici?ncia visual no Ensino Superior??; ?Quais as ferramentas de tecnologia assistiva s?o privilegiadas nas escolhas desses estudantes com defici?ncia visual no seu processo de aprendizagem??; ?Quais s?o os impactos did?tico-pedag?gico das tecnologias usadas no processo de aprendizagem dos estudantes com defici?ncia visual??. Assim, este estudo contribui, adotando a concep??o metodol?gica da Teoria Cr?tica como m?todo, com ?nfase no pensamento de Theodor Adorno, para o desvelar das tramas vivenciadas por estudantes com defici?ncia visual no Ensino Superior p?blico do Amap?. Para tal, utilizamos como procedimento de coleta de dados a entrevista semiestruturada. No avan?o deste estudo, obtivemos como resultado que mesmo com as possibilidades no acesso a acervos bibliogr?ficos em universidades e bases de dados acad?micos, com todas as ferramentas dispon?veis aos estudantes com defici?ncia visual, seja por meio do sistema braille, texto ampliado ou em meio digital, os sujeitos de nosso estudo ainda enfrentam in?meras barreiras did?tico-pedag?gicas.

Entretanto, a baixa disponibilidade h?drica dessas regi?es fronteiri?as tem limitado o desenvolvimento de alguns gen?tipos de eucalipto. ? vista disso, objetivou-se: i) avaliar as respostas morfofisiol?gicas de dois gen?tipos de eucalipto contrastantes quanto ? suas capacidades de tolerar o d?ficit h?drico e ii) construir uma biblioteca g?nica diferencial do gen?tipo tolerante ? seca, de maneira a possibilitar ? compreens?o dos mecanismos subjacentes ? toler?ncia ao d?ficit h?drico do ponto de vista gen?tico-molecular. O experimento foi conduzido, em casa de vegeta??o na UFVJM, em Diamantina, MG. As plantas dos dois gen?tipos, clones 953 (Eucalyptus camaldulensis vs. Eucalyptus grandis) e 224 (Eucalyptus grandis vs. Eucalyptus urophylla), modelo de toler?ncia e sensibilidade ao d?ficit h?drico, respectivamente, foram aclimatadas em casa de sombra, com irriga??o, durante 30 dias. Ap?s esse per?odo, foram submetidos a dois diferentes regimes h?dricos (irrigado e n?o irrigado), quando, ent?o, foram avaliados, ao longo do per?odo experimental, o crescimento em altura e di?metro, ?rea foliar, ?ndice de clorofila total, vari?veis da fluoresc?ncia da clorofila a, vari?veis de trocas gasosas, mat?ria seca de todos os compartimentos da planta e suas rela??es derivadas (rela??o mat?ria seca raiz e parte a?rea, raz?o de massa foliar, ?rea foliar espec?fica e raz?o de ?rea foliar), al?m da sintomatologia do estresse. O experimento foi conduzido em um Delineamento Inteiramente Casualizado, em esquema fatorial 2 (gen?tipos) x 2 (regimes h?dricos), totalizando quatro tratamentos (25 repeti??es cada). As an?lises estat?sticas foram realizadas mediante an?lise de vari?ncia. Para o estudo da express?o g?nica, concomitantemente a aplica??o do estresse h?drico, folhas foram coletadas, congeladas em N2 l?quido e armazenadas a - 80 ?C. Em seguida, procedeu-se com as extra??es e purifica??es do RNA total e, posterior, constru??o da biblioteca subtrativa. A defici?ncia h?drica n?o limitou o crescimento em altura dos gen?tipos estudados, embora, tenha reduzido o di?metro e a produ??o de mat?ria seca total. As demais vari?veis morfofisiol?gicas e todas as vari?veis de trocas gasosas foram negativamente afetadas pelo d?ficit h?drico. O clone 224 mostrou-se menos eficiente em termos fotossint?ticos e mais sens?vel ? restri??o h?drica para a maioria das vari?veis analisadas. Em contrapartida, o 953 apresentou maior toler?ncia ? falta d'?gua. Possivelmente, ?rea foliar reduzida, aumentos no teor de clorofila e aparelho fotossint?tico mais eficiente podem ter sido determinantes nessa maior toler?ncia encontrada no clone 953. Essas estrat?gias, podem, portanto, serem alvos em programas de sele??o de materiais gen?ticos mais tolerantes ? seca. Nesse sentido, a efici?ncia qu?ntica do Fotossistema II mostrou-se uma caracter?stica a ser considerada num processo de sele??o para toler?ncia ? falta d'?gua. A biblioteca de cDNA constru?da permitir? identificar quais genes est?o envolvidos nesse processo de toler?ncia no gen?tipo 953. Futuramente, esses genes candidatos poder?o ser transferidos para gen?tipos de interesse econ?mico, por meio de transgenia. / Disserta??o (Mestrado) ?

However, the low water availability of these border regions has limited the development of some genotypes of eucalyptus. Therefore, we aimed to: i) evaluate the morphological and physiological responses of two contrasting genotypes of eucalyptus as to their ability to tolerate drought and ii) build a library differential gene genotype drought tolerant, in order to enable the understanding molecular mechanisms underlying tolerance to water deficit. The experiment was conducted in a greenhouse at UFVJM in Diamantina, MG. The plants of the two genotypes, 953 clones (Eucalyptus camaldulensis vs. Eucalyptus grandis) and 224 (Eucalyptus grandis vs Eucalyptus urophylla) model of tolerance and sensitivity to water stress, respectively, were acclimated in the shade, irrigated for 30 days. After this period, underwent two different water regimes (irrigated and non-irrigated), when then were evaluated over the experimental period, the growth in height and diameter, leaf area, total chlorophyll index, chlorophyll a fluorescence variables, gas exchange variables, dry matter of all plant parts and their relations derived (shoot/root dry weight ratios, leaf weight ratio, specific leaf area and leaf area ratio) and the symptoms of stress. The experiment was conducted in a completely randomized design in a factorial 2 (genotypes) x 2 (water regimes), totaling four treatments (25 replicates each). Statistical analyzes were performed by analysis of variance. For the study of gene expression, concomitant application of water stress, leaves were collected, frozen in liquid N2 and stored at - 80 ?C. Then proceeded with the extraction and purification of total RNA and subsequent construction of the subtractive library. Water stress did not limit the growth in height of the genotypes studied, although it reduced the diameter and total dry matter production. The other morphophysiological variables and all gas exchange variables were negatively affected by drought. Clone 224 was less efficient photosynthetic and more sensitive to water restriction for most variables. In contrast, the 953 was more tolerant to lack of water. Possibly, reduced leaf area, increases in chlorophyll content and photosynthetic apparatus more efficient may have been determinant to increase tolerance found in clone 953. These strategies can be targeted in selection programs of genetic materials more drought tolerant. In this sense, the quantum efficiency of Photosystem II showed a characteristic to be considered in the selection process for tolerance to water shortage. A cDNA library constructed will allow to identify which genes are involved in the process of tolerance on the genotype 953. In the future, these candidate genes may be transferred to genotypes of economic interest through transgenesis.

Pesquisa do estado de Minas Gerais (FAPEMIG) / O objetivo deste estudo foi analisar representa??es sociais, conhecimentos e pr?ticas relacionadas ao Programa Nacional de Suplementa??o de Vitamina A (PNSVitA), em um munic?pio do Vale do Jequitinhonha. Esse Programa est? institu?do no ?mbito do Sistema ?nico de Sa?de, com vistas ? preven??o/controle da Defici?ncia de Vitamina A (DVA), um dos principais problemas de sa?de p?blica relacionados ? alimenta??o e nutri??o da atualidade. Como aporte metodol?gico, adotou-se a abordagem qualitativa e a Teoria das Representa??es Sociais. Foram realizadas entrevistas semiestruturadas e focalizadas com vinte m?es de crian?as benefici?rias do PNSVitA, sendo esse n?mero definido por inclus?o progressiva, interrompida pelo m?todo de satura??o. As entrevistas foram gravadas, transcritas e submetidas ? an?lise de conte?do na modalidade tem?tica. Com rela??o ?s pr?ticas referentes ao PNSVitA, este estudo revela que a suplementa??o de vitamina A tem sido uma estrat?gia vinculada ao Programa Nacional de Imuniza??o, quest?o que pode ter repercuss?es positivas e negativas. Demonstra que a pr?tica de suplementa??o tem sido desacompanhada de um adequado processo de comunica??o, informa??o e educa??o voltado ? popula??o benefici?ria, o que pode influenciar no conhecimento e nas concep??es que as m?es possuem a respeito da vitamina A, da DVA e do PNSVitA. Indica que a suplementa??o com megadoses da vitamina tem sido a estrat?gia central de preven??o/controle da DVA e sugere a inexist?ncia de atividades voltadas ? promo??o de uma alimenta??o adequada e saud?vel. No tocante aos conhecimentos das m?es acerca da tem?tica em estudo, evidencia-se que, em geral, eles s?o ausentes ou n?o correspondentes ao descrito na literatura cient?fica e t?cnica, quest?o que pode influenciar no reconhecimento da DVA como problema de sa?de p?blica local e na ado??o de corresponsabilidade pelas medidas preventivas. A partir da an?lise dos conhecimentos, com base na Teoria das Representa??es Sociais, este estudo revela que algumas m?es veem a vitamina A como a ?vitamina do posto?, o que indica a concep??o prim?ria desse nutriente como medicamento e n?o como elemento constituinte dos alimentos. Revela a concep??o de que a vitamina A ? uma vacina ou simplesmente uma vitamina (de forma gen?rica) e, por fim, demonstra que essa vitamina ? valorizada pelas m?es, mesmo que, em alguns momentos, elas n?o compreendam sua import?ncia. Conclui-se que, para efetiva preven??o/controle da DVA, faz-se necess?ria a prioriza??o das estrat?gias baseadas em alimentos em detrimento da suplementa??o medicamentosa de vitamina A, tendo em vista o direito humano ? alimenta??o adequada. Al?m disso, faz-se necess?rio o desenvolvimento/fortalecimento de atividades educativas voltadas ? popula??o acerca dessa car?ncia nutricional e das a??es destinadas a sua preven??o/controle. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Sa?de, Sociedade e Ambiente, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2013. / ABSTRACT The objective of this study was to analyze social representations, knowledge and practices related to the National Vitamin A Supplementation Program (PNSVitA in its Portuguese acronym) in a municipality of the Jequitinhonha Valley. This Program has been established within the framework of the Brazilian Unified Health System in order to prevent / control Vitamin A Deficiency (VAD), which is currently one of the major public health problems associated with food and nutrition. As far as methodology is concerned, a qualitative approach and the Social Representations Theory were adopted. Semi-structured and focused interviews were conducted with twenty mothers of children who benefit from the National Vitamin A Supplementation Program, this number being defined by progressive inclusion, interrupted by the saturation method. The interviews were tape-recorded, transcribed and subjected to thematic content analysis. With regard to the practices relating to the National Vitamin A Supplementation Program, this study reveals that vitamin A supplementation has been a strategy linked to the National Immunization Program. This is an issue that may have both positive and negative repercussions. It shows that the supplementation practice has not been accompanied by a proper communication, information and education process targeted at the beneficiary population. This may influence the knowledge and conceptions that mothers possess about vitamin A, VAD, and the PNSVitA. It indicates that supplementation with mega-doses of the vitamin has been the central strategy to prevent / control VAD, and suggests the absence of activities aimed at the promotion of appropriate and healthy eating habits. Concerning the knowledge that mothers possess about the subject area of the study, it is evidenced that, in general, such knowledge is absent or is not consistent with what is described in the scientific and technical literature. This is an issue that may affect the recognition of VAD as a local public health problem and that may influence the adoption of co-responsibility for preventive measures. Based on the analysis of their knowledge, in the light of the Social Representations Theory, this study reveals that some mothers view vitamin A as the ?vitamin from the community health post?, which indicates that this nutrient is primarily perceived as medication, and not as a constituent element of food. It reveals the conception that vitamin A is a vaccin or simply a vitamin (in a generic way), and finally it demonstrates that this vitamin is valued by these mothers, even though at times they do not understand its importance. It is concluded that, for effective prevention / control of vitamin A deficiency, it is necessary to prioritize food-based strategies rather than vitamin A drug supplementation, taking into account the human right to adequate food. In addition, it is necessary to develop / strengthen population-focused educational activities concerning this nutritional deficiency and the actions to prevent / control it.
