A transitividade na conversa����o: uma abordagem funcional centrada no uso

This work investigates the phenomenon of transitivity in the conversation. We examined the behavior of complements in Brazilian Portuguese speech, and then compared the results with previous researches in the English language by Thompson and Hopper (2001) and in the Spanish language by V��zques (2004). In Brazil, there are no researches that treat this phenomenon in the discursive conversation, for that reason it justifies and reveals the importance of this research that aims to answer questions related to the transitivity of ordinary conversations. Thus, we describe, explain and analize the transitivity based on concrete linguistic data, provided by native speakers of Portuguese language, specifically, spontaneous talk of people from Natal-RN. We have used as theoretical assumptions the Functional Linguistics usage-based (LFCU), which gathers academics of North-American Functional Linguistics, inspired by Chafe (1979), Hopper and Thompson (1980), Thompson and Hopper (2001), Giv��n (2001), Bybee (2010), Traugott (2009, 2011), among others, as well as Cognitive Linguistics, presented by Langacker (1987), Taylor (1995), Tomasello (1998) and Goldberg(1995), among others. This data consists in conversations extracted from the corpus Banco Conversacional de Natal (FURTADO DA CUNHA). The results obtained from this work confirm the assertions defined by prior conducted studies on the transitivity in the conversation. The research showed that these three idioms, Spanish, Portuguese and English, despite the differences, they present a uniform behavior regarding their transitivity in the conversation. We intend, by this work, to contribute, in some way, to the comprehension of the focused linguistic phenomenon, likewise to build a finer scenario around of the transitivity in the Brasilian Portuguese

Conectores sequenciadores e e a�� em contos e narrativas de experi��ncia pessoal escritos por alunos de ensino fundamental: uma abordagem sociofuncionalista

In this dissertation, based on two theoretical frameworks, American functionalism and variationist sociolinguistics, I take as subject the sequence connectors E and A��, which has the grammatical function of indicating retroactive-propeller sequenciation of information. I analyze the variable use of these connectors in texts written by students from two public schools in the city of Natal, RN, attending at the time of data collection (the year 2012), two distinct levels of basic education: the sixth and the ninth year. The students who contributed to this research wrote, as part of their activities in the classroom, texts of two narrative genres: narrative of personal experience (non-fictional) and short story (fictional). In addition, these students and their Portuguese teachers answered a test of linguistic attitude in which they gave their opinions regarding the appropriateness of the use of connectors E and A�� in contexts of speech and writing marked by distinct degrees of formality. The results obtained by means of quantitative analysis showed different tendencies of linguistic, social and stylistic distribution of connectors E and A�� in the narrative texts written by the students. I related these results to the action of two principles: the principle of persistence, linked to the process of change by grammaticalization, and the principle of stylistic markedness. Besides, I took into account the answers provided by students and teachers to the test of linguistic attitude for refine the interpretation of the results

A aula de portugu��s no ensino m��dio: o ensino que se deseja, o ensino que se faz

Settled within the realm of a problematization towards teaching and learning the Portuguese language, this study aims to investigate the way how the Portuguese Language discipline is dealt with in Secondary School. We propose specifically to analyze the orientations of the official documents concerning the educator practice, examining the way the PCNEM proposal is approached in the didactic book, identifying the treatment given to language questions, analyzing the way the teacher uses the didactic book and verifying the relations between the official approach and the pedagogical practice. The analysis takes into account the several discourses concerning school literacy, considering the various political-educational instances which institutionalize the teaching of the mother tongue - where we locate the teaching that is wanted . In what teachers and students say in their activities and concerning them - the realm of the teaching that is performed - we presuppose that there are signs of the principles - or conceptions - that orientate what they understand by language, teaching and learning. Such evidences are considered within the interrelation of the enunciative places where this literacy is promoted: the public policies concerning education - focusing the language questions - the academic researches about those questions, the educator formation and capacitation and the very school practices in the complexity of their discoursive inter-subjectivity. The principles - or conceptions - are pursued in what is said (or not) about what is done (or not) in the classroom when dealing with the Portuguese Language. The corpus is made up of oral and written texts produced in Portuguese classes in the Secondary School at a public school in the city of Natal, Rio Grande do Norte, Brazil. Situated in the realm of Applied Linguistics, the research is conducted in a qualitative and interpretative perspective, following the ethnography of communication procedures and the contributions of the Functional Linguistics. In the observations, language conceptions were discerned, among others, besides beliefs and representations where the theoretical and practical aspects, professional roles, expectations and uncertainties were diluted.

O aspecto polif��nico d os Lus��adas

A study about the polyphonic aspect of The Lusiads. An epic poem in Portuguese Language written by Lu��s de Cam��es, that narrates the adventure of the journey of Vasco da Gama in the discoverer of new shipping lanes for the ��ndias. Secondarily, tells the historics battles engaged during the process of foundation and consolidation of the Portuguese Empire. The object of the study are the diverse speeches that compose the poem s narration, aiming at to the possible aesthetic relation of the epic poetry of Cam��es with the novelistic prose developed in the modernity, starting with D. Quijote and consacrating it at polyphonic novels written by Dostoi��vski. The sdudy focuses the singularity of Cam��es lies in the elaboration of a narrative structurally epic, but at the same time contains several deviating speeches. Such speeches emphasize the multiple planes and multiple voices (characteristics of novelistic prose) without, however, prejudice the interlinking logical-formal epos, resulting in the monological finish conventional of the epic gender. This feature characterizes The Lusiads as monological literary work, but also shows dialogism and plurilinguism, essentials to the polyphonic phenomenon. Another prominent aspect of the poetry of Cam��es is the relative procedure to the expressiveness of the characters. They are, in the majority, rhetorical creations, which assume, in the speech, human or myhtological characteristics. Stratagem that permits to the poet to emit a multiple faces of vision of the facts told. The analysis of the speeches supports-itself entirely in the polyphonic theory of Mikhail Bakhtin, shall be cited, accessory, viewpoints of others theoretical, as long if it is judged compatible with the theory adopted

Constru����es com t��pico marcado em cartas pessoais brasileiras dos s��culos XVIII, XIX E XX

This dissertation is a research on the marked topic construction (CT) in Brazilian personal letters from eighteenth, nineteenth and twentieth centuries. The goal of our research is to verify if CT are present in the writing of Brazilians born in the centuries in question. Our research focus is based on the assumptions of generative theory (CHOMSKY 1981; 1986), which states that grammar is internalized in the mind / brain of the writers, with the emphasis on studies of grammatical change, as pointed texts by Paix��o de Sousa (2004), Carneiro (2005); Galves, Namiuti and Paix��o de Sousa (2006) and Martins (2009). Our corpus was extracted from Projeto Para a Hist��ria do Portugu��s Brasileiro (PHPB) and Cartas Brasileiras colet��nea de fontes para o estudo do portugu��s. We selected forty-six correspondents who should be inserted into the two criteria set out in this research: to be Brazilian and be born in the centuries mentioned above, so that we could find legitimate topic constructions of PB. This work is based on researches by Pontes (1987), Mateus et al. (2003), Araujo (2006, 2009), Berlinck, Duarte and Oliveira (2009), which actively support us in the study of this linguistic phenomenon in Portuguese. The results show that the marked topic construction in our corpus appear on the writing of Brazilians since the second half of the eighteenth century, while the typical constructions in Brazilian Portuguese locative topic, subject topic and copy topic - are already reflected in the I-language of the writers born in the second half of the nineteenth century and the first of the twentieth century

Representa����es discursivas de Ficar e Namorar em textos de vestibulandos e pr��-vestibulandos

This doctoral thesis investigate the way vestibulandos and pr��-vestibulandos construct their discursive representations of Ficar and Namorar in their textual production. At the same time, aims to discuss its implications for the ATD and for the teaching and learning of textual production in the context of Portuguese Language classes. Its theoretical framework is inspired mainly by three sources: textual linguistics, the textual analysis of discourses (ADAM, 2008), as well as by frames semantics (FILLMORE, 2006; FELTES, 2007). The methodology is based on a combination of qualitative and quantitative approaches (VIANNA et al., 2008). The data is composed of 168 empirical texts written by the vestibulandos of PSV/2005 da UFRN, Natal, RN, and by secondary school students who attended Escola Estadual Juscelino Kubitschek (EEJK), Ass��, in the 2008 school year. The results indicate different categories of discursive representations of Ficar and Namorar , such as designation of referents, prediction, aspectualization, spatial-temporal circunstances , and metaphor, which reveal the influence of factors such as: the encyclopedic knowledge, the culture, as well as the cognitive components related to textual production. These results point out to the necessity of a teaching practice which enables the interaction among students, the discussion of current themes, as well as the student involvement with different textual genres, mainly the work with textual production in the classroom, so that it enables the students do acquire the textual production strategies. Thus, the overall goal is the (re)construction of their discursive representations, so that they can cope with new contexts of communicative interaction.

A interpreta����o sem��ntica dos auxiliares modais poder, precisar e dever: uma abordagem da sem��ntica cognitiva

Apresentamos, neste trabalho, com base na sem��ntica cognitiva, uma an��lise do significado, em contexto, dos auxiliares modais poder, precisar e dever. Analisamos 120 textos produzidos por candidatos ao vestibular e por alunos do ensino fundamental, como resposta da quest��o n��mero tr��s da prova discursiva de Língua Portuguesa do vestibular 2005 da UFRN, que pede aos candidatos para explicitar a diferen��a de sentido entre tr��s frases, observando o uso desses tr��s verbos. Consideramos que um item lexical n��o �� incorporado a uma representa����o ling����stica sem��ntica fixa, limitada e ��nica, mas antes, �� ligado a uma representa����o ling����stica sem��ntica flex��vel e aberta que prov�� acesso a muitas concep����es e sistemas conceituais dependente de cada contexto determinado. Com base em seu significado, um item lexical evoca um grupo de dom��nios cognitivos, que por sua vez, apresentam um determinado conte��do conceitual. Isto implica em afirmar que a rede de significados lexicais vai variar conforme o conhecimento de mundo de cada um (LANGACKER, 2000). A relev��ncia deste trabalho �� proporcionar uma contribui����o para a descri����o sem��ntica do portugu��s

Veredas infinitas, Recep����o italiana de Grandes sert��es: veredas

L'obiettivo principale di questo lavoro �� valutare le difficolt�� di comprensione e di identificazione nella ricezione da parte della cultura italiana dell'opera Grande sert��o: veredas, da quelle trovate, in modo pionieristico, dal traduttore italiano, a quelle che sono state percepite e indicate al momento della lettura dai critici, dagli accademici, dall'autore di questo lavoro e, soprattutto, dai lettori comuni, mostrando, allo stesso tempo, che i problemi avuti dagli italiani nella traduzione esistono, sotto certi aspetti, anche per i brasiliani urbani, poich�� la dimensione linguistico-geografica presente nel romanzo �� cos�� peculiare, che perfino molti lettori di lingua portoghese ignorano il mondo plasmato dal linguaggio di Guimar��es Rosa rivelando una esacerbazione della questione universale espressa nella formula "traduttori, traditori". Partendo da tutto ci��, abbiamo cercato di dimostrare che, sebbene la traduzione di Edoardo Bizzarri abbia raggiunto un eccellente risultato, l'opera rosiana, cos�� come nella poesia e di pi�� di qualsiasi altra narrativa, comporta, nel passaggio da un idioma all'altro, perdite irrimediabili, tanto relative all'armonia musicale e ritmica, quanto alla richezza semantica che si occulta nel testo originale

Sujeitos e atores sociais nas representa����es discursivas de docentes da rede estadual de ensino em Sergipe: uma an��lise cr��tica em tempos de Ideb

According to the studies in Applied Linguistics, this thesis is based on an interdisciplinary perspective (Critical Discourse Analysis, Sociology towards Social Change, Cultural Studies and Systemic-Functional Linguistics). The overall objective of the research was to analyze the discourses of Elementary School teachers in the state of Sergipe, by means of the discursive representations of the social actors, the processes of subjectivity and their fragmented identities in the context of standardized evaluations before the requirements of globalized pedagogical practices, based on the result-based management. The critical analysis of such discourses was motivated by the rapid pace with which the demands of innovation become part of the classroom, aiming at reaching the target in what concerns the indexes of the rankings which characterize the globalized discourse of the national education management, like Ideb (Basic Education Development Index), which makes teachers change their discourses, become silent or keep resistant. The work was initially endorsed by the theoretical lines of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2006), and poses a proposal for such purpose: the ASCD Discourse Sociological and Communicative Approach (PEDROSA, 2012, 2013). This is an interpretative-qualitative study of the Critical Discourse Analysis (FAIRCLOUGH, 2001, 2003; RAMALHO ; RESENDE, 2011) and to carry it out, semi-structured interviews were used as instruments of data generation (BAUER; GASKELL, 2011; GILL, 2011). Its corpus is composed of thirteen accounts of teachers from the Elementary school who teach Portuguese and work in the fifteen schools which were chosen to be the universe of the research at the Regional Board of Education (02) in the state of Sergipe. Such narratives are related to their impressions, expectations and actions which favor the management of results to which they have to submit themselves. The analytical overview of sociological and discursive line comes from the pan-semiotic categories (Inclusion and Exclusion) which appear in the theory of Representation of Social Actors (VAN LEEUWEN, 1997, 2008). To present the processes of subjectivity of these teachers, this work is based on the socio-analytical proposal of the classification of the subjects, which stems from the individual s work in the Gest��o Relacional de Si , which comes from the Applied Sociology (towards) Social Change (BAJOIT, 2006, 2009). The discursive analyses were guided word for word, in their majority, by having the Systemic Functional Grammar as their theoretical basis, specifically by the processes of the Transitivity System postulated by Halliday, (1985); Halliday and Mathiessen, (2004); Eggins (2004); Cunha and Souza (2011). The work makes the field of Cultural Studies emerge towards the dialogue and the presentation of the fragmented identities of the teachers in the context of late modernity (GIDDENS, 2002; HALL, 2011). The thesis promoted a reflection over the teacher s condition, who is immerse in this context of knowledge construction of the present Brazilian educational system, the standardized evaluations, the indexes of development, the targets and the rankings. The considerations and outcomes of such a research dealt with the teachers emerging social practices and the need of planned initial and continuing teacher education towards the new moment which is foreseeable

O Uso de opera����es lingu��stico-discursivas da cr��tica gen��tica na reescritura de textos

As a professor in Curso de Licenciatura em Letras, from Campus Avan��ado Profa Maria Eliza Albuquerque Maia (CAMEAM),do Estado do Estado do Rio Grande do Norte (UERN), in the town of Pau do Ferros, in the state of Rio Grande do Norte, we had the chance to carry out several writing activities , as well as guiding re-writing activities for the texts produced. From this experience, we started looking at the need of reflecting upon the writing process in higher education. Thus, we aim at analyzing, in this research, the methodology used in the moment of carrying out the writing practices activities in higher education, investigating, in particular, the rewriting practices, concerning the operations used for carrying out such activities, as well as the sense effects produced from the alterations which were made in the texts. Our theoretical foundation is grounded on a conception of text as a verbal action , what reveals a socio-interactional view of the language (MARCUSCHI, 2008; SAUTCHUK, 2003). As the production of written texts, our research focus, we assume that, for this activity, we deal with distinct figures (active writer and internal reader), so that we can, apart from writing, reflecting upon our writing and, this way, deciding about operations which are carried out to make the alterations which are necessary to the rewriting of our texts (SAUTCHUK, 2003). Still about the theoretical foundations used in this research, we made use of the theories from the Textual Analysis of Discourse (TAD) which discusses the belief on the evidence on the existence of the texts, which is opposite to the fixist view of textuality which believes that the texts exist by themselves. (ADAM, 2008; [2005]2010). Under this perspective, we have also adopted, the concepts which come from genetics criticism which is concerned about the relation between text and genesis, using as objects documents which bring traits of the text in progress, on the ground that the text is the result of work in progress, and the writing practice, on the other hand, as an activity in a continuous movement (HAY, [1975]2002; DE BIASI, [2000]2010; GR��SILLON, 1989; [1990]2008; [1992]2002; SALLES, 2008a). The methodology in this research is an ethnography-based one, an approach which focuses on the process, as well as is meaning-based. To understand the objectives proposed in our research, we made use of different procedures of collecting data which include an ethnographic study, such as: observation, note-taking, document analysis. The data which were analyzed were collected during the semester of 2008.2, in a first term classroom of Curso de Letras from CAMEAM, when we were able to collect twenty-one written texts and all of them were rewritten based on rewriting activities, what provides a corpus of forty-two texts which will be analyzed based on the linguistics operations identified by Generative Grammar and adopted by Lebrave and Gr��sillon (2009). From these analyses, we were able to confirm that writing is a process, and rewriting has become an extremely important activity for this process. Still due to these data, we observed that substitution was the most used operation by text authors. We believe that this result is justified by the fact that the substitution, according to what proposes the Genetic Criticism, constitutes the source of all erasure, from which one can easily make a change in writing. Regarding the operations of addition and deletion, we found that they were used in quantitative terms, almost equivalently, which can be explained when we see that the two operations require, by the author of the text, different strategies from those used for the replacement, what includes , respectively, adding or removing a segment. Finally, we found out that the shift operation was the least used, since it works with a segment that will not be replaced, added or deleted, but transferred to another place of text, which requires a greater ability of the author to perform this operation and not compromising the meaning of his/her writing. As a result, we hope to contribute to the reflection on the teaching of writing, considering, in a particular way, those with a Bachelor in Arts. Our analysis will contribute to the teaching of Portuguese language, specifically for activities that guide the production of texts in order to explore with students the ability to rewrite their own text

Did��tica do plurilinguismo: efeitos da intercompreens��o de línguas rom��nicas na compreens��o de textos escritos em portugu��s

This exploratory study aims to present some readings as Doy�� (2003), Carrasco Perea (2003), Melo Ara��jo e S�� (2004), Chavagne (2009) and Alas-Martins (2010; 2011) which helped to confirm some ways for showing that a plurilingual environment can enable a trend in improving the understanding of written texts in the mother tongue, and can collaborate on a better perception of the world around a person with all their different nuances. The study describes the methodology and some results of our doctoral research that resulted in the insertion of the experimental discipline called Intercomprehension of Romanic Languages (ILR) in the curriculum in the city of Natal / RN / Brazil, and it was justified because of high functional illiteracy degree among young people up to 15 years old according to the educational data from IBGE research on 2010. The results were verified through an experimental action-research which was characterized by Lewin (1946); Nunan (1992); Thiollent (1994) and Trip (2005) in two schools: Professoara Terezinha Paulino de Lima (municipal school) and Professora Ana Julia de Carvalho Mousinho (State of Rio Grande do Norte), with 95 students from the final years of primary education. The corpus of this research was subjected to a series of condensed techniques like the nonparametric test from Kruskal and Wallis (1952) and the parametric test ANOVA as an effort to provide statistical significance to the analysis of the results indicated in the book of ILR activities. The research presented some skill views about reading comprehension of written texts according to perspective of Ringbow (1987), Giacobbe (1990), Alarc��o (1991; 2009a and 2009b), Corder (1992), Castellotti (2001) and Degache (2003), and the possibilities of transfer these skills for learning Portuguese as pointed out by Meissner, Klein and Stegmann (2004); it indicates a positive trend towards the understanding of LM according to analyzing the scores of written tests and texts by participants in solving tasks

Manual do professor, muito prazer em (re)conhec��-lo! Uma an��lise sociorretorica do g��nero

Esta pesquisa de natureza documental e etnogr��fica se insere no campo da Lingu��stica Aplicada, tendo por objeto de estudo o Manual do Professor, que acompanha o livro did��tico de Língua Portuguesa, e por objetivo geral (re)conhecer os aspectos sociorret��ricos do g��nero Manual do Professor. O interesse desta tese est�� concentrado no uso situado desse g��nero, a partir do qual se observam seus aspectos sociorret��ricos, a saber: o que est�� posto no produto, o ambiente de intera����o onde �� encontrado e como �� visto por seus usu��rios em potencial. Em um primeiro momento, produzimos um quadro epistemol��gico que nos permitiu, dentre outros reparos, (i) compreender g��nero textual como a����o ret��rica tipificada baseada numa situa����o ret��rica recorrente e (ii) obter um panorama dos programas de governo voltados para a avalia����o de colet��neas did��ticas, nos quais encontramos aspectos indispens��veis a um Manual do Professor. Os aportes te��ricos adotados neste estudo referem-se �� concep����o sociorret��rica dos estudos de g��nero textual �� luz, sobretudo, de Johns et al. (2006), Bazerman (2011) e Miller (2011). Em um segundo momento, sob o vi��s da abordagem sociorret��rica, procuramos definir o Manual do Professor como g��nero textual e apresentamos os aspectos ret��ricos encontrados nas amostras que analisamos, considerando a organiza����o constitutiva, o contexto de uso desse g��nero e as percep����es de seus usu��rios autores e professores. A gera����o de dados deu-se inicialmente a partir da sele����o de tr��s exemplares de Manuais de colet��neas did��ticas adotadas no IFRN; em seguida, no sentido de reconhecer as percep����es dos usu��rios desse g��nero, realizamos grupo focal com professores e entrevistamos o coautor de uma das colet��neas. Para an��lise dos dados, elegemos o m��todo etnogr��fico de an��lise de g��neros postulado por Reiff (apud JOHNS et al, 2006), que nos permitiu analisar o objeto de estudo em contextos aut��nticos de uso do g��nero. Nossos resultados mostram que o Manual do Professor est�� inserido num sistema de g��neros e no sistema de atividades profissionais de dom��nio do professor e n��o se limita apenas a explicar como est�� organizado o livro did��tico do aluno. Outros sete prop��sitos foram observados, dentre os quais se encontram: possibilitar ao docente uma reflex��o sobre a sua pr��tica de ensino e sugerir caminhos para a melhoria do processo de ensino-aprendizagem. Acreditamos que esta pesquisa poder�� estimular professores, em rela����o �� import��ncia (e n��o obrigatoriedade) de consultas peri��dicas aos Manuais; autores, no que se refere a estabelecer uma interlocu����o mais pessoalizada com seus leitores em potencial e no sentido de esclarecer ainda mais as facetas do livro did��tico; e editoras, sobretudo no que tange a recursos de editora����o, para que o Manual do Professor se torne mais atrativo

Tradu����o, adapta����o cultural e propriedades psicom��tricas da vers��o brasileira do Short-Form of the Mobility Assessment Tool (MAT-sf)

Objectives: to translate and assess the psychometric properties of the Brazilian short-form of the Mobility Assessment Tool (MAT-sf) in Brazilians community elderly. Methds: the 12 items MAT-sf went through the process of translation and back translation into Portuguese of the Brazil, considering the semantic and cultural adaptation. In a sample of 150 aged 65-74 years living in the community, the instrument's psychometric properties were evaluated by analysis of convergent and construct validity and test-retest reliability. The main outcomes measures used for validation included in the battery of tests of physical ability, self-repor measures of functional limitations, health, depression, cognitive and sex. The test-retest reliability of the instrument was assessed using the intra-class correlation coefficient (ICC), 40 subjects were reassessed after an interval of 14 days of assessment. Results: the concurrent validity for the MAT-sf was evidenced by significant correlations with SPPB (r = 0,53), number of functional limitations (r = -0,62) and depressive symptoms (r = -0,45). The construct validity of the instrument was measured by gradual and significant increase of the MAT-sf scores with high levels of physical performance and with positive self-reported health, also found that MAT-sf scores were statistically differents according to sex. The variation in MAT-sf scores (R2 = 0,41) was explained by SPPB, number of limitations for activities of daily life and depressive symptoms. High values for test-retest reliability was evidencend by ICC = 0,94, 95% CI = 0,90 0,97. Conclusions: the Brazilian version of the short-form of the Mobility Assessment Tool has values of validity and reliability to ensure its use in elderly populations living in communities

Influ��ncia do sistema de fornecimento de oxig��nio na qualidade de vida de pacientes com hipoxemia cr��nica

OBJETIVO: Avaliar a qualidade de vida relacionada �� sa��de de pacientes com doen��a obstrutiva cr��nica das vias a��reas recebendo oxigenoterapia domiciliar prolongada (ODP) por meio de cilindros de oxig��nio e comparar estes resultados com os obtidos ap��s seis meses de modifica����o do sistema de fornecimento para concentradores de oxig��nio. M��TODOS: Um total de 45 pacientes, 24 com hipoxemia cr��nica e 21 sem evid��ncias de hipoxemia, foram avaliados. Os pacientes com hipoxemia cr��nica estavam recebendo ODP regularmente durante pelo menos os ��ltimos seis meses e foram avaliados no momento basal, em uso de cilindro, e ap��s seis meses de transi����o para concentradores. Os pacientes n��o hipox��micos foram avaliados no mesmo intervalo de tempo que os pacientes hipox��micos. Para avaliar a qualidade de vida foi utilizada a vers��o validada para língua portuguesa (Brasil) do Question��rio Respirat��rio Saint George (Saint George's Respiratory Questionnaire - SGRQ). RESULTADOS: No momento inicial, os pacientes hipox��micos apresentaram maior comprometimento da qualidade de vida, avaliada pelo escore total e pelos escores dos dom��nios sintomas e impacto do SGRQ, que os pacientes n��o hipox��micos. Ap��s seis meses, houve melhora significativa da qualidade de vida dos pacientes hipox��micos e, neste momento, n��o foi encontrada diferen��a entre os pacientes com e sem hipoxemia. CONCLUS��O: Nossos achados mostraram que os pacientes com doen��a obstrutiva cr��nica das vias a��reas e hipoxemia cr��nica apresentam preju��zo da qualidade de vida, que essa qualidade de vida pode ser melhorada com o uso regular de ODP e que o sistema de fornecimento de oxig��nio tem influ��ncia nessa melhora.
