Uma solução para geração automática de trilhas em língua brasileira de sinais em conteúdos multimídia

Deaf people have serious difficulties to access information. The support for sign languages is rarely addressed in Information and Communication Technologies (ICT). Furthermore, in scientific literature, there is a lack of works related to machine translation for sign languages in real-time and open-domain scenarios, such as TV. To minimize these problems, in this work, we propose a solution for automatic generation of Brazilian Sign Language (LIBRAS) video tracks into captioned digital multimedia contents. These tracks are generated from a real-time machine translation strategy, which performs the translation from a Brazilian Portuguese subtitle stream (e.g., a movie subtitle or a closed caption stream). Furthermore, the proposed solution is open-domain and has a set of mechanisms that exploit human computation to generate and maintain their linguistic constructions. Some implementations of the proposed solution were developed for digital TV, Web and Digital Cinema platforms, and a set of experiments with deaf users was developed to evaluate the main aspects of the solution. The results showed that the proposed solution is efficient and able to generate and embed LIBRAS tracks in real-time scenarios and is a practical and feasible alternative to reduce barriers of deaf to access information, especially when human interpreters are not available

A formação de professores surdos de Libras: a centralidade de ambientes bilíngues em sua formação

The study object of this thesis intertwines the history of deaf education in the last 30 years in three schools for the deaf in the cities of Campina Grande, Gado Bravo and Aroeiras, Paraiba, the life stories of six deaf teachers of brasilian sign language (Libras) that have formed and works in these educational institutions for the deaf and our own journey, as a teacher and researcher. The study was conducted on the theoretical-methodological principles of (auto)biographical research in education and socio-historical studies on the social formation of the human. The corpus used for analysis was consisted of six narrative interviews conducted in sign language and transcribed into portuguese, documents and personal files and institutional. The analysis allowed us to define three hinge moments of this story: the creation of the first school for the deaf, within the framework of oralism (1980 - 1991), the passage into the Total Communication (1991 - 1995) and, finally, the introduction of Bilingualism (1995 to today). The analyzes show that the trajectories of teacher formation of the research participants reflect the history of the three schools which have costituted bilingual social spaces of paramount importance to the subjects and the deaf community as a group of linguistic and cultural minority. The evolution of this trajectory has allowed to demarcate between the two generations of research participants. The generation of heirs of oralism, which had delayed access to the Libras and lived an education referenced in oralism, whose reminiscences of childhood and adolescence are strongly marked by suffering for the lack of communication, which hinders their social and professional career until today. And the generation of the sons of bilingualism, the youngest in age, who had childhood access to Libras and education within the framework of bilingualism, whose reminiscences are not marked by suffering and have a positive vision of the future. With respect to your teacher formation, three figures stand out as a teacher. The teacher's improvised, closer to the first generation of teachers who were called to teach without proper training. The figure of the teacher craftsman, which corresponds to the image that most of them have of yourself now, understanding that their knowledge are based on the exchange between peers. And finally the figure of the real teacher, which stands on the horizon of expectations as future graduates in Letters |Libras. The narratives allowed to realize that the evolution between these figures is based on the contributions of the other: hearing teachers of EDAC and the Federal University of Campina Grande and deaf teachers of the two generations who learn from each other. The analyzes and reflections allowed to defend the thesis of the centrality of bilingual environments for the establishment of the deaf person as a citizen with full rights, based on the voice of the deaf, muted by the history of education, conducted by listeners

Percepção da equipe de saúde, discentes e usuários sobre a comunicação com indivíduos surdos na atenção primária

The study aimed to identify in the professionals and students of health courses that work in a health Basic Unit in the city of Natal/RN their perceptions of the care of deaf patients, and with the population's needs with hearing loss in relation to health care. This is a cross-sectional, exploratory, descriptive study, conducted between April to July 2014, with a population composed of 21 health professionals, 17 students and 8 deaf users. For data collection, we used a structured questionnaire with open and closed questions applied to groups composed of health professionals (doctors, dentists, nurses and health workers) and students of medical schools, nursing, physical education, nutrition and social service. The professionals/students answered a semi-structured questionnaire with open and closed questions concerning the possible difficulties the care of the deaf and hearing impaired. Data collection with deaf users was conducted through filmed interview for the Brazilian Sign Language (Libras) could be interpreted as to the Portuguese by the researcher. With the latter it was conducted a survey of their reactions when looking for a care in the health service. Regarding the profile of identification of the subjects, it was analyzed by simple descriptive statistics (absolute and relative frequencies). The open questions were analyzed through the content analysis technique which allowed the categorization process preserving all the points raised in the discussion so that the lines were representative of the whole. When asked about the professionals and students attitude used to communicate with deaf patients possible the following categories emerged: the "writing", the "gestures" and the "third party assistance". With regard of the deaf, when asked about their experiences in seeking care in health, the elucidated categories were: "quality of care to the hearing impaired", "communication with the hearing impaired adequacy" and "dependence on third parties." The closed questions were measured and adapted to the 5 degrees of variation Likert Scale, which comprised three of these issues: degree of difficulty in communication to meet a patient with hearing loss (minimum to great difficulty); feeling of comfort while using sign language (minimum to severe discomfort); and knowledge of the Law 10.436, which provides for the Brazilian Sign Language (Libras) (low knowledge to entirely clear). The data collected with professionals and students revealed some misunderstanding and discomfort in health care for deaf patients, reality also evidenced in the opinion of the deaf participants. This study revealed problems in communication, resulting in negative consequences in serving this population. This diagnosis may be relevant to public policy development and curriculum guidelines essential to the training of health professionals, inclusion and improving assistance to deaf.

Escolarização de surdos no ensino médio em Natal/RN: vendo e ouvindo vozes

La Escuela Secundaria es la etapa final de la Educación Básica y su objetivo es profundizar los conocimientos adquiridos anteriormente, con vistas tanto a la continuidad de los estudios por parte de los alumnos como también a su formación profesional. Considerando el carácter excluyente y elitista de la Escuela Secundaria brasileña, solo recientemente las matrículas de los estudiantes sordos comienzan a ampliarse, y los profesores se deparan con el desafío de lidiar con ese tipo de discente en aulas regulares. Tanto la política de educación especial, desde una perspectiva inclusiva, como la Ley nº 10.436/2002 – reglamentada por el Decreto nº 5.626/2005 – posibilitaron un gran salto para la educación de los sordos en el país. La primera, por la defensa de una escuela atenta a las peculiaridades y demandas de sus discentes; la segunda, por reconocer la Lengua de Señas Brasileña como medio de comunicación y expresión legítimo de la comunidad de sordos y por indicar medidas que garanticen el derecho al acceso y al éxito escolar de la población sorda dentro de la escuela. Amparado en esas discusiones, este estudio tuvo como objetivo analizar el proceso de escolaridad de alumnos sordos de una Escuela Secundaria pública y estatal del municipio de Natal, Rio Grande do Norte. Se realizó un estudio de caso de tipo cualitativo. Los sujetos fueron tres discentes sordos que estaban terminando la Escuela Secundaria, una profesora de Portugués y dos intérpretes de Lengua de Señas Brasileña. Como procedimiento de investigación, se utilizaron entrevistas (grabadas en audio y video), observaciones y análisis de documentos. La participación de los sujetos sordos demandó cuidados éticos adicionales, tales como la traducción del Término de Consentimiento Libre y Aclarado y del guion de la entrevista a la Lengua de Señas Brasileña. Los resultados apuntan que el acceso y la permanencia en la escuela secundaria fueron garantizados, no obstante había poca participación en las clases y el aprendizaje de los contenidos escolares estaba comprometido. Había traductores/intérpretes de Lengua de Señas Brasileña, los cuales, sin embargo, solo iniciaron sus actividades tres meses después del comienzo del periodo lectivo. La profesora y los intérpretes no mantuvieron interacciones que facilitasen el aprendizaje o la participación de los estudiantes, quienes se encontraban siempre juntos y en un lugar determinado del aula, sin mayores interacciones con sus pares normo-oyentes. Los discentes sordos estaban terminando la Escuela Secundaria con edades superiores a 17-18 años, los cuales revelaron no tener perspectivas de continuidad en sus estudios o de inserción en el mercado laboral. Se concluye que la escolaridad de los alumnos sordos en la escuela investigada apunta a la necesidad de una reorganización curricular que atienda a las especificidades lingüísticas y sociales de esos estudiantes.

Currículo escolar e inclusão de estudantes com deficiência: diálogos com uma escola pública

This work of qualitative approach, has as its study object the school curriculum, resulting from the implementation of public policies for inclusion in the Brazilian educational field and of the teaching organization in State School Despertar. While we acknowledge advances in government discussions and proposals related to school inclusion in our country, it is still important to develop studies and interventions in the context of basic education focused on the curriculum. With methodological basis in collaborative-critical action research and contribution by Barbier, the survey was conducted in 2013, in a state school in the Natal - Rio Grande do Norte - school system, and aimed to analyze the curriculum of the State School Despertar, in particular issues related to the inclusion of students with disabilities in common teaching classes expressed in the school and in collective situations of continuing education with teachers and interpreter of Brazilian Sign Language (Libras). The school was previously chosen because it had already been locus of research in a study conducted by a professor at the Federal University of Rio Grande do Norte promoting the knowledge of their formative needs. The study subjects were 26 teachers in the early years and the end of elementary school and a Libras interpreter. The instruments were direct observation, semi-structured interviews, document analysis and a proposal for continuing education called Collaborative Group on School Inclusion (GCEI), established with the participating subjects and the other research collaborators. The analyzed data showed eight dialogues built with the State School Despertar, being basic the contributions of Goffman (1988) on stigma and of Forquin (1993) on school culture. As a theoretical framework, there were important contributions on School Curriculum (SACRISTÁN, 2000; 2007; APPLE, 2006; 2008), School Inclusion (BUENO, 2008), Continuing Education (NÓVOA, 2002; GATTI, 2003) and the existing studies on the dialogues between Curriculum and Special Education (MAGALHÃES, 2002; SILVA, 2008; 2010; OLIVEIRA, 2004; VIEIRA, 2012). The study highlighted the importance of extending the dialogue, the theoretical deepening of GCEI for the understanding of school curriculum and the specifics of any students, with or without disability. It will be necessary to revisit the school teaching practices that do not correspond to the students, for instance the formation of classes made in classrooms. It is also important to consider the organization of the school day and its interface with the pedagogical functions of each member of the school in building curriculum practices consistent with the diversity of modes and learning styles. Subliminal aspects of the curriculum should be reviewed, given its implications in the context of the classroom and management. However, significant changes identified in the practices of some teachers, such as the use of audio description, stimulus to the participation of students with disabilities and use of images, favored the development of other students, who benefit of more exciting and participatory classes. Based on the conducted research, we conclude on the importance of collectively discuss the conditions for / in schooling of different students and the (re)thinking of curriculum practices in the school as a whole, and therein lies a paradox because, on the one hand, it is not about minimizing the specific knowledge in dealing with the needs of students with disabilities, on the other, we are not interested in distancing these needs from those inherent in human nature, therefore peculiar to the other students. The questioning of our own practices is the challenge imposed, not to special education, or its target audience, but this is undoubtedly task of education.

Efeitos de tempestades magnéticas em sinais de gps, em Natal, Brasil

Satellites signals present disturbances (scintillations), due to presence of irregularities in the ionospheric plasma. In the present work, we dedicate to the study of the attenuation of these scintillations that is, an improvement in the signal, during the main magnetic storm phase during the period of October 2006 to February 2007. Using amplitude of scintillation 1.5GHz (L1) data of the net of satellites GPS, in the ionospheric station of Natal (5.84o S, 35.20o O, -20o dip) and geomagnetic indices, during the minimum solar cycle (referred to as cycle 23), demonstrating its anti-correlation between magnetic activity (Kp) and index of scintillation () (Bonelli2005 method, that works for solar maximum, Bonelli(2005)). These results show that these storms correspond to category I of Aarons (1991). The magnetic storms can generate irregularities when the electric feld of penetration eastward on the pre-reversal hour intensificating that and can too generate irregularities on midnight and sunlight period. The limitation of the method applied here is that it is not considering some storms that had also occurred during equinox and summer in the Brazilian region. For this reason, we will use additional data of the stations of São João de Cariri (Imager and Photometer) and of the station at Fortaleza (Digissonde data), as aid to analyze these storms. The storms that had been left out by the applied method, fit in the other two categories of Aarons, with one only exception (storm of January, 02). We show that in the day of the main phase of the magnetic storm, and with presence of bubbles (according to data of the Imager and Photometer), the speed of vertical drift ~E ~B (hF=t) is below 20m/s, that is the threshold found for Anderson al., (2004) (>20m/s as condition favorable to the formation of irregularities and increase in the scintillation index). This reduction of the speed is due to solar minimum

Estudo sobre a relação entre a atividade geomagnética e cintilações de sinais de GPS em Natal-RN (Brasil)

To identify the relationship between GPS scintillation in Natal-RN (Brazil) and geomagnetic disturbances of any intensities and variations, this work made analysis of the ionospheric behavior and magnetic indexes (Dst , AE and Bz of the interplanetary magnetic field) concerning to different periods of the solar cycle between 2000 and 2014. Part of the data of this research originated at the UFRN observatory, from a GEC Plessey board connected to an ANP -C 114 antenna, modified by Cornell University’s Space group Plasma Physics in order to operate the ScintMon, a GPS monitoring program. This study, therefore, found several cases of inhibited scintillations after the main phase of magnetic storms, a fact that, along with others, corroborated with categorization of Aarons (1991) and models of disturbed dynamo (according to Bonelli, 2008) and over-shielding penetration, defended by Kelley et al. (1979) and Abdu (2011) [4]. In addition to these findings, different morphologies were noted in such disruptions in the GPS signal in accordance with previous magnetic activities. It also found a moderate relationship (R2 = 0.52) between the Dst rate (concerning to specific time) and the average of S4 through a polynomial function. This finding therefore, corroborating Ilma et al. (2012) [17], is an important evidence that the scintillation GPS are not directly controlled by magnetic induction of storms. Completing this work, this relation did show itself as a way of partial predicting of scintillations.

Métodos:76 pacientes com Diabetes Melito tipos 1 e 2atendidos no ambulatório de Oftalmologia e Cirurgia Vascular do HUOL/UFRN, Natal, RN, no período de novembro de 2004 a janeiro de 2005, com queixas relativas a alterações da retinopatia diabéticae/oudo pé diabético. Em todos os pacientes foi realizado exame clínico geral, vascular e oftalmológico. Na avaliação específicado pé diabético deu-se ênfase paraa investigação do status vascular pela Classificação de Fontaine para Doença Arterial Obstrutiva Periférica, biomecânica,e teste do monofilamento de Semmes-Weinstein. O exame oftalmológico constou de refração e fundoscopiaatravés da qual identificou-se as formas clínicas da retinopatia diabética. Os dados foram submetidos à análise estatística das variáveis primárias que consistiu em caracterizar o grupo quanto a idade, tempo de doença, nível de glicose A segunda estratégia da análise dos dados constituiu na realização de testes de associação entrealgumas variáveis secundárias selecionadas. O software utilizado para os testes estatísticos foi o Statistica Versão 5, 1997.Resultado: Dos 76 pacientes diabéticos 97% tinham idade superior a 40 anos. O tempo de doença65% tinham mais de 10 anos. Com relação à glicose 72,72% apresentaram níveis de glicose em jejum acima de 100mg/dl. 55,26% apresentavam algum grau de retinopatia diabética contra 44,74% que não apresentavamesses sinais. Com as alterações do pé diabético, identificou-se 59,93% com lesões com área de predominância isquêmica, enquanto 41,07% tinham ausência de sinais. 58,82% apresentaram área de predominância neuropática, e 41,18% sem sinais de neuropatia. Dos com retinopatia diabética 78,57% tinham comprometimento isquêmico no pé e 47,62% tinham algum grau de neuropatia diabética. Observou-se que a retinopatia diabética não proliferativa, nos seus diversos graus de comprometimento apresentou-se com percentuais em torno de 80% junto às lesões do pé diabético, seja isquêmico ou neuropático. Dos pacientes que tinham retinopatia 60,46% tinham alterações biomecânicas dos pés. Conclusão: Concluiu-se que a RDNP leve foi mais freqüente nas lesões do pé diabético isquêmico, enquanto a RDNP severa mostrou-se mais presente no pé diabético neuropático

O fenômeno da corrupção na esfera pública brasileira

This work aims to understand the phenomenon of corruption in the Brazilian public sphere and its implications for society. It has brought concepts of corruption, and has referred to its highest incidence in the public sphere in the three levels of government (despite its infiltration also in the privative sector) and has called attention to two subjects which intertwine public administration (as a means of ordering social life) and corruption (as a form of denial to the collective welfare). Through literature search whose analysis shows that the phenomenon contains the entire country history, from discovery to present day it was found to be common several dictatorial and democratic political regimes. Finally, it has emphasized the importance and necessity of citizen participation in process, as well as the organization of civil society and media, in addition to highlighting the relevance of autonomy and independence of Powers set for its effective confrontation and fighting

Genotoxicidade e composição do material particulado emitido pela queima de Biomassa: um estudo de caso em Tangará da Serra, Região da Amazônia Brasileira

Tangara da Serra is located on southwestern Mato Grosso and is found to be on the route of pollutants dispersion originated in the Legal Amazon s deforestation area. This region has also a wide area of sugarcane culture, setting this site quite exposed to atmospheric pollutants. The objective of this work was to evaluate the genotoxicity of three different concentrations of organic particulate matter which was collected from August through December / 2008 in Tangara da Serra, using micronucleus test in Tradescantia pallida (Trad-MCN). The levels of particulate matter less than 10μm (MP10) and black carbon (BC) collected on the Teflon and polycarbonate filters were determined as well. Also, the alkanes and polycyclic aromatic hydrocarbons (PAHs) were identified and quantified on the samples from the burning period by gas chromatography detector with flame ionization detection (GC-FID). The results from the analyzing of alkanes indicate an antropic influence. Among the PAHs, the retene was the one found on the higher quantity and it is an indicator of biomass burning. The compounds indene(1,2,3-cd)pyrene and benzo(k)fluoranthene were identified on the samples and are considered to be potentially mutagenic and carcinogenic. By using Trad-MCN, it was observed a significant increase on the micronucleus frequency during the burning period, and this fact can be related to the mutagenic PAHs which were found on such extracts. When the period of less burnings is analyzed and compared to the negative control group, it was noted that there was no significant difference on the micronuclei rate. On the other hand, when the higher burning period is analyzed, statistically significant differences were evident. This study showed that the Trad-MCN was sensible and efficient on evaluating the genotoxicity potencial of organic matter from biomass burning, and also, emphasizes the importance of performing a chemical composition analysis in order to achieve a complete diagnosis on environmental risk control

Processamento Inteligente de Sinais de Pressão e Temperatura Adquiridos Através de Sensores Permanentes em Poços de Petróleo

Originally aimed at operational objectives, the continuous measurement of well bottomhole pressure and temperature, recorded by permanent downhole gauges (PDG), finds vast applicability in reservoir management. It contributes for the monitoring of well performance and makes it possible to estimate reservoir parameters on the long term. However, notwithstanding its unquestionable value, data from PDG is characterized by a large noise content. Moreover, the presence of outliers within valid signal measurements seems to be a major problem as well. In this work, the initial treatment of PDG signals is addressed, based on curve smoothing, self-organizing maps and the discrete wavelet transform. Additionally, a system based on the coupling of fuzzy clustering with feed-forward neural networks is proposed for transient detection. The obtained results were considered quite satisfactory for offshore wells and matched real requisites for utilization
