In this study I will examine the general view among preschool teachers on the use of sign as support as a complement in order to enhance communication. I have focused this work on children between the one and three years of age. The main aim of this study is to investigate how sign as supportis used in the daily work in different preschool and how this method affects the development of verbal communication between the children and teachers. I want to find out more about the general view and the advantages and possible disadvantages this method introduces on the daily work among the teachers who actually uses this tool. This is particularly important as the foundation of the children’s ability to continue to grow and developed are made during this time.To help the younger children improve their communication skills it is the view of this author that sufficient support and tools are required at an early stage, preferably as early as possible, task to provide the teachers with sufficient means to accomplish this. A web enquiry is used as the main tool to get an up to date information about how the teachers use sign as support these days as well as the opinions about its advantages and disadvantages where a number of relevant questions are putto the participatingteachers.The result show for example that a majority, 96 of 100, findssign as support very helpful approach. Only fourfound other means more appropriate on an individual basis. Additionally, it was found that digital media and tools were not a tool commonly applied when using the sign as supportmethod. This suggests that the potential for improving the sign as supportmethod further seem very promising in the future. / I min studie undersöker jag några pedagogers syn på användandet av Tecken som Alternativ och Kompletterande Kommunikation (TAKK). Jag har valt att inrikta mig på de pedagoger som arbetar med de yngrebarnen (1-3 år). Syftet med min studie är att undersöka hur TAKK används i verksamheten och hur den utifrån pedagogernas perspektiv påverkar de yngre barnens språkutveckling. Jag vill därför få en inblick i hur pedagoger som använder TAKK upplever verksamheten med hjälp av detta hjälpmedel. Förskolans verksamhet är viktig eftersom denna tid i livet högst avsevärt påverkar hur barnet kommer att utvecklas i framtiden. För att de minsta ska få en bra start på sin språkutveckling anser jag att det är väsentligt att de får rätt stöd och verktyg av oss pedagoger på förskolan för att utveckla sitt språk i så tidigt stadium som möjligt. Genom att använda mig av metoden webbenkät kan jag få ett bra underlag på hur metoden TAKK används och upplevs i dagens samhälle med hjälp av ett antal relevanta frågor som presenteras för respondenterna i enkäten. I mitt resultat kommer det fram att en stor majoritet, 96 respondenter av 100, tycker att TAKK hjälper alla små barn med deras språkutveckling på ett bra sätt. Endast fyra respondenter tycker att de hjälper barn med behov av språkstöd bäst i sin språkutveckling genom att ge dessa extra stödåtgärder individuellt. Dessutom framkommer det att digitala media ännu inte har något större stöd i användandet av TAKK vilket antyder att metoden har stor potential för att utvecklas ytterligare.

O objetivo deste trabalho foi conhecer a história de vida de alunos surdos, matriculados em instituições de ensino superior na cidade de São Paulo, contada por eles mesmos, por meio da Língua de Sinais, a língua natural dos surdos. Para compor o material de estudo, objeto deste trabalho, foram entrevistados quatro alunos surdos, matriculados em instituições de ensino superior e do setor privado e também um professor universitário, também surdo, que leciona a língua brasileira de sinais - Libras em uma universidade da cidade de São Paulo. As entrevistas dos alunos contaram com a participação de um intérprete de Libras, enquanto o professor de Libras preferiu o método oral para responder às nossas perguntas, que tiveram como objetivo conhecer as suas histórias de vida em cinco aspectos, os quais não foram abordados necessariamente na ordem aqui colocada: família, infância, escola, comunicação e surdez. O objetivo foi o de conhecer a vivência dos entrevistados em cada um desses aspectos e como a surdez influenciou suas vidas nessas esferas, e, como também cada um relata suas experiências de vida. Os relatos mostraram que ser surdo em uma sociedade composta por uma maioria ouvinte, representou uma condição de desvantagem em um ou mais dos aspectos abordados, sendo que a falta de comunicação foi a principal dificuldade apontada por todos os entrevistados. A riqueza dos relatos aparece nas formas como eles contaram as suas vidas e na ênfase que cada um colocou nos diferentes aspectos abordados. As singularidades desses relatos revelaram que os surdos compõem um grupo social distinto, não apenas devido à sua condição física que os impossibilita de ouvir os estímulos sonoros, mas sobretudo pela forma como se inserem e interagem em um ambiente majoriatariamente ouvinte. Nesta interação ocorre a singularidade da pessoa por meio do comunicação por sinais ou oral. / The objective of this study was to know more about the life and background of deaf students enrolled in higher education institutions located in the city of São Paulo. Each student presented his report in sign language - the deaf\'s natural language. To compose the study material object of this work, four deaf students in private higher education institutions and a deaf professor, who teaches brazilian sign language - Libras in a University in São Paulo, were interviewed. A Libras interpreter took part in the students\' interviews. The professor preferred the oral method in order to answer the questions. The questions targeted at five aspects on their life, not necessarily approached in the order presented: family, childhood, school, communication and deafness. The goal was to approach the interviewees\' experience in each of the aspects and how each one reports his life experiences. The narratives estate that being deaf in a society composed by a majority of listeners represented a disadvantage at one or more of the approached aspects. The shortage of communication was presented as the main difficulty by all interviewees. The richness of the narratives appears in the means they told their stories and the emphasis on the different approached aspects. The reports\' singularity reveals that the deaf can be classified as a distinct social group, not only for their physical condition, which prevents them from hearing, but specially, by the way they are inserted and interact in a mostly common hearing environment, without implying a denial of one\'s singularity.

Research conducted on the prevalence of behavioural adjustment in Deaf children and adolescents, in erstwhile countries, points towards an appreciably elevated percentage of emotional and behavioural problems amongst this population group when compared to hearing normative groups. Studies specify that the prevalence of behaviour and emotional problems in Deaf children and adolescents varies from 4.8% to 50.3%. From existing research conducted, it is ambiguous as to why the reported prevalence rates of maladjustment are higher amongst Deaf children and adolescents. This pioneering study is the first of its kind to research dissimilar modalities of language used as the language of learning and teaching (LoLT) in schools for Deaf learners and how this could possibly correlate to learner behaviour in the classroom. Taking into consideration the reported pervasiveness of maladjustment in Deaf children and adolescents; this study uses the Teacher Report Form (TRF) to investigate the types of behaviour problems displayed by Deaf learners in the classroom. It further investigates whether Deaf learners display certain types of behaviour problems when dissimilar modalities of language are used as the language of learning and teaching. The overall findings of this study suggest that teachers who use manually coded spoken language report an elevated prevalence of behaviour problems on the TRF compared to teachers who use South African Sign Language (SASL). Results further suggest that the group of teachers who use SASL report somatic complaints and attention problems as the most frequently encountered behaviour problems in their classrooms. In comparison the group of teachers who use manually coded spoken English (MCE) report social problems and attention problems as the most frequently encountered behaviour problems in their classrooms. Limitations of this study and suggestions for future research are discussed.

Notre contribution porte sur les processus de conceptualisation et de modélisation de la matière et de ses transformations en chimie. Elle s'articule autour de deux parties. Une première partie consistant en une analyse du type sémioépistémologique de ce processus pendant la période fin XVIIIe - début XIXe siècles. Nous mobilisons pour cela la théorie sémiotique de C.S. Peirce comme cadre d'analyse. Elle a permis de resituer l'expérimental de la chimie comme étant un ensemble de signes qui prolonge le théorique en même temps qu'il le fonde. Le signe iconique loin d'être signe d'une pensée primitive apparait comme une véritable néo écriture, un instrument heuristique privilégié utilisé par les chimistes pour sonder la matière à la recherche d'indices sur une structure pouvant rendre compte de son comportement, il leur a permis, après de nombreuses controverses, d'aboutir à une structure particulaire, et de construire les concepts d'atome, la molécule et son atomicité. Une deuxième partie où l'analyse sémio-épistémologique a constitué notre cadre théorique pour une transposition didactique de ce contexte. Notre question de recherche est de savoir si le signe iconique, comme défini au sens peircien, peut être mobilisé de manière spontanée par les élèves de 13-15 ans pour construire un raisonnement en chimie, et s'il peut les aider à accéder à l'infiniment petit sur la base de ce contexte transposé ? Nous avons alors élaboré un corpus de 20 séquences d'enseignement engageant les élèves dans une démarche qui nécessite la construction de modèles évolutifs. Nos résultats permettent de dire que le signe iconique loin d'être un moyen pédagogique de transmission facilité, un auxiliaire didactique est au contraire un instrument heuristique privilégié dans la construction des connaissances par les élèves, comme il l'est chez le chimiste / Our contribution focuses on the process of conceptualization and modeling of matter and its transformations in chemistry. It consists of two parts. A first part consisting of an analysis of the semio-epistemological type of this process during the late 18th - early 19th centuries. We mobilize for this semiotic theory of C.S. Peirce as a framework for analysis. It allowed to relocate the experimental chemistry as being a set of signs that extends the theoretical at the same time that he founded. The iconic sign far from signs of a primitive thought appears as a true neo writing, a privileged heuristic instrument used by chemists to probe the matter for clues on a structure that can make account of his behavior, he allowed them, after much controversy, lead to a particulate structure, and build the concepts of atom, the molecule and its atomicity. A second part where the semio-epistemological analysis was our theoretical framework for a didactic transposition of this context. Our research question is to know if the sign iconic, as defined in the peircien sense, can be mobilized spontaneously by students from ages 13-15 to build reasoning in chemistry, and if he can help in accessing the infinitely small on the basis of this converted context? We then developed a corpus of 20 sequences of teaching engaging students in a process that requires the construction of evolutionary models. Our results to say that the iconic sign far from a pedagogical means of transmission facilitated, a teaching assistant is instead a heuristic instrument in the construction of knowledge by students, as it is at the chemist

Comment La langue vient à l’enfant sourd selon qu’il se trouve dans un environnement sourd ou entendant ?Telle est la question que tente de mettre au travail cette thèse de psychologie clinique.L’histoire des sourds du moyen-âge jusqu’à nos jours comporte différentes positions idéologiques quant à l’accès au langage. Encore aujourd’hui la position « phonocentrée » reste prépondérante. La personne sourde est perçue comme une personne handicapée qu’il faut rééduquer. Les appareillages les plus sophistiqués, les séances d’orthophonie, doivent faire parler l’enfant sourd. La langue des signes ne reste qu’un pis-aller, non réellement investie comme une langue à part entière dans l’éducation de l’enfant sourd.Le bébé sourd naît le plus souvent dans un environnement entendant. La découverte de la surdité n’a lieu qu’aux environs du second semestre de la vie du bébé. Ce diagnostic représente un véritable traumatisme psychique pour les parents entendants. Ils se sentent le plus souvent trahis par ce « nouveau » bébé. L’urgence de la rééducation orale vient colmater la blessure narcissique faite aux parents. Dans ce contexte, le risque est grand pour le bébé de perdre l’étayage du « miroir environnement » et de se retrouver face à un vécu de « déprivation ». La surdité représente une autre manière d’être au monde, une autre manière de l’appréhender et d’interagir avec lui. Etre sourd aux bruits environnants ne signifie pas être sans langage. La langue des signes est une invention humaine extraordinaire qui nécessite de changer de paradigme. Elle interroge la problématique de la communication en général.Comment le bébé sourd interagit avec son environnement sourd et entendant? Ce bébé sourd présente une sensorialité spécifique qui nécessite un positionnement relationnel particulier de la part de son environnement entendant.L’observation filmée de trois dyades mère-bébé sourd, âgés de deux mois à deux ans, propose quelques éléments de réponse Le rythme, dans la clinique de la rencontre, apparaît comme un concept essentiel dans l’accordage de la dyade mère-bébé. / How does a child acquire language whether it finds itself in a deaf environnement or a normal (hearing) one ?That is the question that this clinical psychology thesis inquires.The history of the deaf community through the Middle Ages until today is composed of different ideological positions concerning how language is acquired. Until today, the « phonocentric » position remains preponderant. The deaf person is percieved (apprehended) as a handicapped person who needs to be re-educated. The most sophisticated material, speach therapy sessions, are supposed to make the deaf child speak. Sign language remains the last resort, not really considered as a language, in all senses of the term, when used as education for the deaf child.The deaf baby is most frequently born in a normally hearing environment. Discovery of deafness only occurs around the second semester of the baby’s life. This diagnosis can represent an absolute trauma for normally hearing parents. They often feel betrayed by this « new » baby. The emergency of getting oral re-education started is an attempt to make up for the narcissic wound inflicted on the parents. In this context, there is a great risk that the baby will lose the propping up of the « mirror environment » only to find itself confronted with a feeling of « deprivation ».Deafness represents a different way of being in the world, another way of apprehending and interacting with it. Being deaf to environing noise does not imply being without language. Sign language is an extraordinary human invention which implies changing the paradigm. It questions the problem of communication in general.How does the deaf baby interact with both normally hearing and a deaf environment ? The deaf baby has specific sensoriality which requires a particular relational position on behalf of its normally hearing environment.The video-observation of three mother-deaf baby dyads, from two months old to two years of age, proposes parts of a reply to these questions. Rythm, in the clinical situation of meeting, appears as a fundamental concept concerning the getting together of mother and baby dyad.

Este trabalho teve como objetivo observar, analisar e discutir como ocorre a busca por sinais-alvo, em indivíduos surdos, fluentes na Língua Brasileira de Sinais (Libras); verificar se ocorre, nesses indivíduos o fenômeno ponta dos dedos (TOF); e descrever os aspectos fonético-fonológicos na ocorrência do fenômeno. O TOF corresponde ao fenômeno ponta da língua (TOT) nas línguas orais. Esse fenômeno ocorre quando há o esquecimento momentâneo de palavras conhecidas e o sentimento de que essa palavra está prestes a ser recuperada. Tal fenômeno oferece pistas sobre o processamento da linguagem e a recuperação lexical. Poucos trabalhos foram realizados sobre este fenômeno nas línguas de sinais (THOMPSON; EMMOREY; GOLLAN, 2005) e essa investigação é importante, pois, por ser uma língua de modalidade distinta (visual-espacial), possui processos fonológicos particulares. Nesse sentido, foi elaborado um teste para eliciar o fenômeno em 34 adultos surdos, que relataram utilizar a Libras como principal meio de comunicação. O teste consistia na realização do sinal referente a personalidades famosas e a cidades no mundo. Foram exibidas imagens e o participante deveria dizer se sabia ou não o sinal referente à pessoa ou à cidade, ou se estava experienciando o TOF. Neste último caso, o participante deveria sinalizar o que lembrasse do sinal- alvo. Foram realizados 69 estímulos por participantes, somando um total de 2346 estímulos e, como resultado obtivemos a ocorrência de 20 TOFs (0,9% dos estímulos). Em todos os casos de TOF foi recuperado ao menos um dos parâmetros fonético-fonológicos (quais sejam, configuração de mão, localização/ espaço, orientação, movimento, número de mãos). Dos parâmetros fonético-fonológicos recuperados, a configuração de mão foi recuperada em 65% dos casos (13 vezes); a localização em 70% (14 vezes); o espaço em 85% (17 vezes); o movimento em 35% (7 vezes); a orientação em 50% (10 vezes); e o número de mãos em 90% dos casos (18 vezes). Corroboramos a conclusão de Thompson, Emmorey e Gollan (2005) de que o movimento é o parâmetro menos recuperado no momento do TOF. Esse fato pode indicar que os parâmetros localização, configuração de mão e orientação (mais recuperados no momento do TOF) constituem o onset da estrutura silábica do sinal, isto é, o segmento inicial do sinal. Além disso, a ocorrência do fenômeno ponta dos dedos na Libras ajuda a confirmar separação, no processamento da recuperação lexical em codificação semântica e codificação fonológica estabelecidas em modelos de recuperação de línguas orais (DELL, 1986; GARRETT, 1988; LEVELT, 1989). / The aim of this research is to analyze and discuss how the search for target signs occurs in the lexical retrieval in deaf people using Brazilian Sign Language (Libras); to verify if the \"tip of the fingers\" (TOF) phenomenon occurs; and describe the phonological aspects in the occurrence of the phenomenon. The TOF phenomenon mirrors the \"tip of the tongue\" phenomenon in oral languages. This phenomenon occurs when there is momentary forgetfulness of known words and the feeling that this word is about to be recovered. This phenomenon offers clues about language processing and lexical retrieval. Few studies have been carried out on this phenomenon in sign languages (THOMPSON; EMMOREY; GOLLAN, 2005) and this research is important because sign language has a different modality and therefore it has particular phonological processes. In this sense, a test was prepared to elicit the phenomenon in 34 deaf adults, who reported using Libras as the main means of communication. The test consisted of the signing regarding proper names of famous personalities and cities in the world. Images were displayed and the participant should say whether or not he knew the sign for the person or city, or whether he was experiencing TOF. In the latter case, the participant should sign what he remembered of the target signal. A total of 69 stimuli were performed per participant, totaling 2346 stimuli and, as a result, we obtained the occurrence of 20 TOFs (0.9% of the stimuli). In all TOF cases, at least one of the phonological parameters (ie, hand configuration, location / space, orientation, movement, number of hands) was retrieved. Of those, the hand configuration was recovered in 65% of the cases (13 times); the location in 70% (14 times); space 85% (17 times); movement in 35% (7 times); orientation by 50% (10 times); and the number of hands in 90% of the cases (18 times). We corroborate the conclusion of Thompson, Emmorey and Gollan (2005) that movement is the least recovered parameter at the time of TOF. This fact may indicate that the parameters localization, hand configuration and orientation (more retrieved while in TOF state) constitute the onset of the syllabic structure of the sign. In addition, the occurrence of the \"tip of the fingers\" phenomenon in Libras helps to confirm separation, in the processing of lexical retrieval in semantic encoding and phonological encoding established in lexical retrieval models of oral language (GARRETT, 1988; LEVELT, 1989).

As produções artísticas do pintor Kazuo Wakabayshi podem ser divididas em duas etapas. A primeira é um conjunto de obras de tonalidade escura, de tom universal e sem qualquer indicação de sua origem étnica. A segunda fase, que se inicia por volta dos anos de 1980, consiste em obras de cores vibrantes, cujo detalhe apresenta elementos da cultura japonesa, tais como personagens do teatro kabuki, estampas da indumentária tradicional e outros elementos pertinentes àquela cultura. Apesar das notáveis diferenças entre as duas etapas, a elipse é a forma geométrica que sempre existiu na vida artística de Wakabayashi. O propósito da presente tese é trazer à tona o que está imerso nessas criações, primeiramente de natureza universal e, posteriormente, identitária. Acredito que a compreensão da arte desse artista imigrante poderá trazer respostas acerca da história de sua vida / The artistic productions of the painter Kazuo Wakabayashi, who spent his teenage years during the World War II can be divided in two stages. The first one is represented by the group of paintings in dark tones, which lacks any sign of ethnic origin, and which seeks to preserve a universal tone. The second stage, which begins in 1980s, consists of vibrant colours paintings, whose details are rich on Japanese culture elements, such as the Kabuki play characters, the patterns of traditional clothing, among other elements. Although there are striking differences between these two stages, the ellipsis is the geometric form which has never left his artistic life. The present thesis seeks to bring to the surface what is immersed in the depth of these productions in his first stage, which has an universal character and in the later one, after the acception of his ethnic identity. The understanding of his work will enable us to find answers on the personal life of this Japanese immigrant artist

A presente tese consiste numa pesquisa de caráter lingüístico descritivo. O objetivo é o de oferecer critérios para a segmentação do discurso na língua de sinais brasileira (libras) em unidades gramaticais. Duas linhas teóricas contribuíram para este projeto de forma crucial: a análise da conversa de base etnometodológica e a gramática baseada no uso. A análise da conversa, ao observar o modo como os próprios participantes se orientam uns em relação aos outros na interação, revela uma visão dos recursos gramaticais como práticas sociais voltadas à realização e coordenação de ações sociais na conversação. A gramática baseada no uso, ao explorar as relações entre língua, cognição e interação, revela o importante papel da prosódia e da gestualidade para o estabelecimento da atenção conjunta na interação. Na constituição do corpus, díades formadas por surdos adultos fluentes em libras foram gravadas num estúdio, com iluminação e câmeras posicionadas de modo a captar o rosto e o espaço de sinalização dos falantes, além de ambos em perfil. Um trecho da gravação foi selecionado para ser transcrito e utilizado como ponto de referência principal da análise, que envolveu duas etapas distintas. Na primeira fase, é demonstrado que o princípio do um-de-cada-vez, uma manifestação da atenção conjunta no nível do discurso, também se mostra operante numa língua de modalidade gestual-visual como a libras. Na segunda fase, uma análise sobre a segmentação interna dos turnos de fala sinalizados é realizada por meio da combinação de uma abordagem com foco nas unidades entoacionais do discurso, e uma abordagem com foco em práticas estruturadas do discurso, tais como listas e contrastes. As principais contribuições que resultaram do trabalho foram: i) um repertório sistematizado de recursos manuais e não-manuais da libras que pode servir como ponto de referência inicial para a segmentação do discurso espontâneo em unidades gramaticais; e ii) uma abordagem para a segmentação do discurso que, em futuras investigações, poderá permitir um maior aprofundamento de nosso conhecimento acerca dos recursos prosódicos da libras. / This dissertation comprises a study in descriptive linguistics. The aim is to elaborate criteria for the segmentation of Brazilian Sign Language (Libras) discourse into grammatical units. Two theoretical fields contributed crucially to this project: conversation analysis and usage-based grammar. Conversation analysis, by focusing observation on how participants themselves orient to each other in interaction, has revealed a perspective on grammatical resources as social practices designed for the deployment and coordination of social actions in conversation. Usage-based grammar, by exploring the relations among language, cognition and interaction, reveals the important role of prosody and gesture for the establishment of joint attention in interaction. In the construction of the corpus, dyads composed of fluent adult speakers of Libras were recorded in a studio, with lights and cameras positioned in order to capture both the face and the signing space of each of the speakers, in addition to the two speakers in profile. An excerpt from one of the conversations was selected to be transcribed and used as the main point of reference for the analysis, which involved two distinct phases. In the first phase, it is demonstrated that the principle of one-at-a-time, a manifestation of joint attention at the level of discourse, also holds in a language of gestural-visual modality like Libras. In the second phase, the internal segmentation of turns at talk is analyzed, by combining an approach focused on the minimal prosodic units of discourse with an approach focused on structured practices of discourse, such as lists and contrasts. The major contributions resulting from the analysis are: i) a systematized repertoire of manual and non-manual resources of Libras which can serve as an initial point of reference for the segmentation of signed discourse into grammatical units; and, ii) an approach to the identification of prosodic units which, in future investigations, may permit further advancements with respect to our understanding of the prosodic resources of Libras.

Este trabalho representa a reflexão e o conhecimento buscado e construído a partir do que aconteceu quando uma comunicadora resolveu desenvolver um projeto de comunicação audiovisual numa outra comunidade – a dos surdos - em que a comunicação com os de fora é uma barreira. Chegar com 'meu' projeto, achando que seria bom 'para eles', foi pura pretensão. O desenvolvimento do projeto - seu tempo, seu modo, sua expressão, sua língua e sua linguagem – teria que ser uma busca cujo tempo e maneira não poderiam ser estabelecidos por mim. Para me recuperar do impacto dessa constatação óbvia e quase ingênua, fui buscar orientação nos conceitos de cultura de Clifford Geertz, de identidade de Stuart Hall, de pensamento e linguagem de Vygotsky, de história de Peter Burke, de narrativas de Hayden White e Ecléa Bosi, nas histórias exemplares e inspiradoras de Oliver Sacks, na aprendizagem da comunicação com a língua de sinais e, sobretudo, na convivência com a comunidade surda. Mais observando e sendo observada do que propondo intervenções que pudessem 'desarranjar' uma cultura construída com dificuldades significativas. O mais importante descrito neste trabalho foi o processo, que me levou à experiência que hoje vivo, 'convidada' a construir novas conquistas, agora COM a comunidade. O resultado audiovisual foi um vídeo feito com fotografias da Associação dos Surdos de São Paulo (ASSP), sem som, limitado por datas: a da festa de 50 anos da ASSP e a da entrega da minha dissertação. A ausência de som não representa apenas apertar o 'mudo' do controle remoto, mas uma outra forma de comunicação e de ver o mundo. Meu trabalho, de fato, está começando agora. / This work represents the reflection and the knowledge researched and built over what happened when a communicator decided to develop an audiovisual communication project within a community – the deaf community - whose the communication with the outsiders is such a barrier for them. To get there with 'my' project, believing that would be good 'for them' was pure pretension. The development of the project - its time, its way, its expression, its language – would have to be a way that could not be set by me. To recover me from the impact of this obvious and almost ingenuous evidence, I looked for orientation on the concepts about culture of Clifford Geertz, about identity of Stuart Hall, about thought and language of Vygotsky, about history of Peter Burke, about narratives with Hayden White and Eclea Bosi, on the exemplar and inspiring histories of Oliver Sacks, on the communication Sign Language learning and, mainly, on the companionship with the deaf community. More observing and being observed than proposing interventions that could 'disarrange' a culture built with meaningful difficulties. The main part descript in this work was the process that guided me to the experience I’ve been living today, 'invited' to build new conquests, now WITH the community. The audiovisual result was a video made with pictures of the Deaf Association of Sao Paulo, with no sound, limited by dates: the Association 50-year party’s, and the delivery of my dissertation´s. The absence of sound doesn’t represent only to press the 'mute' bottom of the remote control, but another way of communication and perceiving the world. My work, indeed, is beginning now.

This dissertation aims to perform collections of Radio Signal Strength Indicator (RSSI), to suggest a method to analyze the signal behavior and to subsidize criteria for decision making, when the signal presents significant instability. The expected benefit is the characterization of this environment, allowing knowledge about the behavior of this type of network, which today, although necessary, is still limited, thus contributing to the development of reliable applications that use this type of network. The results of the signal strength measurements have been analyzed for their stability. / Trabalho cient?fico que demonstra o comportamento da intensidade do sinal em uma Rede de Sensores sem Fio (RSSF) no ambiente industrial.
