RESUMO

OBJECTIVE: to analyze YouTube videos with information about COVID-19 in Brazilian sign language. METHODS: a cross-sectional study conducted with 402 videos from the YouTube sharing platform. Chi-square, Fisher's exact, Mann-Whitney and Spearman's correlation tests were used. RESULTS: the videos mainly covered COVID-19 prevention (20.6%). There was a positive correlation between video length and number of views (p<0.001). The length of more than 20 minutes was associated with narration only in BSL (p=0.37) and in BSL with audio (p<0.001), while videos with less than 20 minutes were associated with simultaneous narration in BSL, audio and subtitles. Those with narration only in BSL had a similar number of views to those narrated with subtitles and/or audio (p=0.998). CONCLUSION: the videos were mostly short and included COVID-19 prevention. The longer the video, the greater the number of views. Regardless the presentation of narrations, the videos had a similar number of views.

RESUMO

Sign language is the most important way of communication for hearing-impaired people. Research on sign language recognition can help normal people understand sign language. We reviewed the classic methods of sign language recognition, and the recognition accuracy is not high enough because of redundant information, human finger occlusion, motion blurring, the diversified signing styles of different people, and so on. To overcome these shortcomings, we propose a multi-scale and dual sign language recognition Network (SLR-Net) based on a graph convolutional network (GCN). The original input data was RGB videos. We first extracted the skeleton data from them and then used the skeleton data for sign language recognition. SLR-Net is mainly composed of three sub-modules: multi-scale attention network (MSA), multi-scale spatiotemporal attention network (MSSTA) and attention enhanced temporal convolution network (ATCN). MSA allows the GCN to learn the dependencies between long-distance vertices; MSSTA can directly learn the spatiotemporal features; ATCN allows the GCN network to better learn the long temporal dependencies. The three different attention mechanisms, multi-scale attention mechanism, spatiotemporal attention mechanism, and temporal attention mechanism, are proposed to further improve the robustness and accuracy. Besides, a keyframe extraction algorithm is proposed, which can greatly improve efficiency by sacrificing a little accuracy. Experimental results showed that our method can reach 98.08% accuracy rate in the CSL-500 dataset with a 500-word vocabulary. Even on the challenging dataset DEVISIGN-L with a 2000-word vocabulary, it also reached a 64.57% accuracy rate, outperforming other state-of-the-art sign language recognition methods.

RESUMO

Objetivo: verificar a influência da comunicação dos pais no recebimento de informações e comportamento de saúde de filhos surdos. Método: estudo transversal realizado com 110 pessoas surdas, selecionadas com a técnica snowball sampling, em municípios no Noroeste do estado do Paraná. Os dados foram coletados de fevereiro a agosto de 2019, mediante aplicação de instrumento estruturado. Na análise dos dados utilizou-se a estatística descritiva e inferencial. Resultados: a maioria dos surdos (95,4%) recebeu alguma orientação de saúde no núcleo familiar; ser orientado sobre a importância de consultas de rotina mostrou-se associado à realização da mesma pelos filhos no último ano (OR= 3,40). O pai que sabe se comunicar em Libras constituiu fator de proteção, pois, nestes casos, ocorreram mais orientações sobre o uso de drogas e consumo abusivo de açúcar. Conclusão: a habilidade comunicacional dos pais possibilita que eles realizem mais orientações relacionadas à saúde e isto influencia o comportamento em saúde de filhos surdos.


Objective: to ascertain the influence of parents' communication on deaf children's reception of health information, and health behavior. Method: in this cross-sectional study of 110 deaf people selected by snowball sampling in municipalities in northwest Paraná state, data were collected from February to August 2019 using a structured instrument. Descriptive and inferential statistics were used in the data analysis. Results: most deaf people (95.4%) received some health guidance in the family; being guided about the importance of routine appointments was found to be associated with the children's attending such appointments in the prior year (OR = 3.40). The parent able to communicate in Libras was a protective factor, because in these cases, more guidance on drug use and sugar abuse occurred. Conclusion: the parents' communication skills enabled them to provide more health-related guidance, and this influenced their deaf children's health behavior.


Objetivo: determinar la influencia de la comunicación de los padres en la recepción de la información sanitaria y el comportamiento sanitario de los niños sordos. Método: en este estudio transversal de 110 personas sordas seleccionadas por muestreo de bola de nieve en municipios del noroeste del estado de Paraná, los datos se recolectaron de febrero a agosto de 2019 mediante un instrumento estructurado. Se utilizó estadística descriptiva e inferencial en el análisis de datos. Resultados: la mayoría de las personas sordas (95,4%) recibió alguna orientación sanitaria en la familia; Se descubrió que el hecho de recibir orientación sobre la importancia de las citas de rutina estaba asociado con la asistencia de los niños a dichas citas el año anterior (OR = 3,40). El padre capaz de comunicarse en Libra fue un factor de protección, porque en estos casos, hubo más orientación sobre el uso de drogas y el abuso de azúcar. Conclusión: las habilidades de comunicación de los padres les permitieron brindar más orientación relacionada con la salud, y esto influyó en el comportamiento de salud de sus hijos sordos.

RESUMO

PURPOSE: to know the family interaction with the hearing impaired child/adolescent. METHODS: descriptive and exploratory qualitative research developed at a Special School in Southern Brazil. Participants were 10 primary caregivers of deaf children/adolescents between 10 and 19 years old. The collection took place in November 2017, through semi-structured interviews containing questions about the communication process of deaf children/adolescents with their families. The information was analyzed through thematic analysis. The study was submitted and approved by the Ethics Committee under opinion number 2.333.560. RESULTS: as the main theme of the study "Interaction between the family and the child/adolescent with hearing impairment", it addresses two sub-themes: potentialities and weaknesses in the communication of the family with the child/adolescent with hearing impairment and learning in the care of the child/adolescent with hearing impairment. CONCLUSION: it was identified that the interaction of the deaf with the family and society is impaired by people's lack of knowledge about the deaf community and the Brazilian Sign Language, which raises concern in caregivers who often overprotect the child/adolescent which may limit the full development of their skills and autonomy.

RESUMO

INTRODUCTION: In Brazil, there is a considerable number of deaf people, sign language users, who should have access to equal opportunities. However, sign language is unknown by the most Brazilian population, especially those who work in public institutions, and deny the deaf their rights to equality. Therefore, several professionals, among them, the municipal guards, are not prepared for the diversity. PURPOSE: to investigate the knowledge of the Municipal Guards (MG) from Curitiba about the deaf, Brazilian Sign Language (Libras),and their service practices when they need to interact with deaf citizens. METHOD: It´s a mixed crosscut study; data were collected by the application of a semi-structured questionnaire answered by 50 municipal guards, with questions on their knowledge about the deaf, the sign language and the service practices conducted by their corporation towards deaf people. Data were analyzed quantitatively and qualitatively by means of Bardin's Content Analysis. RESULTS: The results demonstrate that participants have a limited knowledge of deafness and Libras. CONCLUSION: Most members of the Municipal Guard have a view of deaf people and the Brazilian Sign Language based on an organic perspective of deafness, and it was also observed that during their service practices towards deaf people, many of them could not either interact or communicate with them.

RESUMO

BACKGROUND: The coronavirus disease 2019 pandemic has necessitated rapid adaptations to all levels of clinical practice. Recently produced guidelines have suggested additional considerations for tracheostomy and advocated full personal protective equipment, including filtering facepiece code 3 masks. Air seal with filtering facepiece code 3 masks is often challenging, and full-face respirators and powered air-purifying respirators with hoods need to be employed. The infection prevention benefits of this equipment are accompanied by potential issues in communication. OBJECTIVE: In an attempt to minimise surgical error through miscommunication, the authors sought to introduce a simple sign language system that could be used as an adjunct during surgery. RESULTS: Following evaluation of pre-existing sign language platforms and consideration of multiple surgical factors, 14 bespoke hand signals were ultimately proposed. CONCLUSION: Whilst this novel sign language system aims to bridge the communicative gap created by additional personal protective equipment, further development and validation of the proposed tool might be beneficial.

RESUMO

Language provides a rich source of information about other people's thoughts and feelings. Consequently, delayed access to language may influence conceptual development in Theory of Mind (ToM). We use functional magnetic resonance imaging and behavioral tasks to study ToM development in child (n = 33, 4-12 years old) and adult (n = 36) fluent signers of American Sign Language (ASL), and characterize neural ToM responses during ASL and movie-viewing tasks. Participants include deaf children whose first exposure to ASL was delayed up to 7 years (n = 12). Neural responses to ToM stories (specifically, selectivity of the right temporo-parietal junction) in these children resembles responses previously observed in young children, who have similar linguistic experience, rather than those in age-matched native-signing children, who have similar biological maturation. Early linguistic experience may facilitate ToM development, via the development of a selective brain region for ToM.

RESUMO

Motor simulation has emerged as a mechanism for both predictive action perception and language comprehension. By deriving a motor command, individuals can predictively represent the outcome of an unfolding action as a forward model. Evidence of simulation can be seen via improved participant performance for stimuli that conform to the participant's individual characteristics (an egocentric bias). There is little evidence, however, from individuals for whom action and language take place in the same modality: sign language users. The present study asked signers and nonsigners to shadow (perform actions in tandem with various models), and the delay between the model and participant ("lag time") served as an indicator of the strength of the predictive model (shorter lag time = more robust model). This design allowed us to examine the role of (a) motor simulation during action prediction, (b) linguistic status in predictive representations (i.e., pseudosigns vs. grooming gestures), and (c) language experience in generating predictions (i.e., signers vs. nonsigners). An egocentric bias was only observed under limited circumstances: when nonsigners began shadowing grooming gestures. The data do not support strong motor simulation proposals, and instead highlight the role of (a) production fluency and (b) manual rhythm for signer productions. Signers showed significantly faster lag times for the highly skilled pseudosign model and increased temporal regularity (i.e., lower standard deviations) compared to nonsigners. We conclude sign language experience may (a) reduce reliance on motor simulation during action observation, (b) attune users to prosodic cues (c) and induce temporal regularities during action production.

RESUMO

OBJECTIVE: to build and validate the content on Cardiopulmonary Resuscitation (CPR) of a sign language instrument for assessing the knowledge of the deaf. METHOD: methodological study in which the content validity process was used by 22 specialists in cardiac arrest and 16 deaf people. In the validation of internal consistency, 113 deaf people participated. For the assessment of the deaf, the Assistive Technology Assessment Questionnaire was used and, in the content validity, an instrument with a Likert scale was used, which included the content, clarity, objectivity, organization and language. Items with a minimum agreement of 80% were considered valid, according to the Content Validity Index (CVI) and binomial test. The internal consistency was verified by Cronbach's alpha. RESULTS: The instrument contains 11 questions about the identification of cardiorespiratory arrest, activation by aid and high quality chest compression. It had a minimum content validity of 81% by the specialists, 90% by the deaf participants and internal consistency by the Cronbach alpha of 0.86, being considered high. CONCLUSION: the instrument can be used in research to survey the previous knowledge of deaf people about CPR, as well as in pre and/or post-testing studies that test educational interventions with this public.

RESUMO

Facial expressions in sign languages are used to express grammatical functions, such as question marking, but can also be used to express emotions (either the signer's own or in constructed action contexts). Emotions and grammatical functions can utilize the same articulators, and the combinations can be congruent or incongruent. For instance, surprise and polar questions can be marked by raised eyebrows, while anger is usually marked by lowered eyebrows. We investigated what happens when different emotions (neutral/surprise/anger) are combined with different sentence types (statement/polar question/wh-question) in Kazakh-Russian Sign Language (KRSL), replicating studies previously made for other sign languages. We asked 9 native signers (5 deaf, 4 hearing children of deaf adults) to sign 10 simple sentences in 9 conditions (3 emotions * 3 sentence types). We used OpenPose software to track eyebrow position in the video recordings. We found that emotions and sentence types influence eyebrow position in KRSL: eyebrows are raised for polar questions and surprise, and lowered for anger. There are also some interactions between the two factors, as well as some differences between hearing and deaf native signers, namely a smaller effect of polar questions for the deaf group, and a different interaction between emotions and wh-question marking in the two groups. We thus find evidence for the complex influences on non-manual behavior in signers of sign languages, and showcase a quantitative approach to this field.

RESUMO

The study of deaf users of signed languages, who often experience delays in primary language (L1) acquisition, permits a unique opportunity to examine the effects of aging on the processing of an L1 acquired under delayed or protracted development. A cohort of 107 congenitally deaf adult signers ages 45-85 years who were exposed to American Sign Language (ASL) either in infancy, early childhood, or late childhood were tested using an ASL sentence repetition test. Participants repeated 20 sentences that gradually increased in length and complexity. Logistic mixed-effects regression with the variables of chronological age (CA) and age of acquisition (AoA) was used to assess sentence repetition accuracy. Results showed that CA was a significant predictor, with increased age being associated with decreased likelihood to reproduce a sentence correctly (odds ratio [OR] = 0.56, p = .010). In addition, effects of AoA were observed. Relative to native deaf signers, those who acquired ASL in early childhood were less likely to successfully reproduce a sentence (OR = 0.42, p = .003), as were subjects who learned ASL in late childhood (OR = 0.27, p < .001). These data show that aging affects verbatim recall in deaf users of ASL and that the age of sign language acquisition has a significant and lasting effect on repetition ability, even after decades of sign language use. These data show evidence for life-span continuity of early life effects. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

RESUMO

O objetivo do presente estudo foi identificar e compreender as representações sociais de discentes surdos em relação à sexualidade. Esta pesquisa teve como aporte teórico a Teoria das Representações Sociais (TRS), que permite elucidar os aspectos históricos, culturais e políticos que cercam o sujeito e, com isso, acessar o conhecimento proveniente do senso comum. Foram entrevistados 10 estudantes surdos de forma individual, em Língua Brasileira de Sinais (LIBRAS), por meio de um roteiro semiestruturado. Utilizou-se o software IRAMUTEQ para a análise dos dados mediante a Classificação Hierárquica Descendente (CHD). Percebeu-se que as representações sociais dos participantes sobre a sexualidade estão ancoradas na saúde sexual, nas relações com os pares, família e nas relações íntimas de afeto. O presente estudo identificou a importância das informações acessíveis para o surdo e da participação dos familiares e da escola na ampliação do conhecimento sobre a temática em questão.


This study aimed to identify and understand the social representations of deaf students regarding sexuality. This research had as theoretical contribution the Theory of Social Representations that allows elucidating the historical, cultural and political aspects that surround the subject and with this access the knowledge coming from the common sense. Ten deaf students were interviewed individually, in the Brazilian Sing Language (LIBRAS), through a semistructured script. The IRAMUTEQ Software was used to analyze the data using the Descending Hierarchical Classification (DHC). It was realized that the social representations of deaf students about sexuality are anchored to the care with sexual health, the sexual pleasure, the care with the appearance and in the relations of friendship and loving. This study identified the importance of accessible information for the deaf and the participation of the family and the school in the expansion of the knowledge on the subject in question.

RESUMO

O objetivo da pesquisa foi adaptar para Libras, a Língua Brasileira de Sinais, a Escala Multidimensional de Satisfação de Vida para Adolescentes (EMSVA). A adaptação foi realizada em seis etapas: 1) adaptação semântica e tradução para Libras; 2) síntese das versões traduzidas; 3) avaliação da síntese por juízes; 4) análise semântica da escala em Libras; 5) retrotradução e 6) análise empírica. Nas três primeiras etapas e na retrotradução, os participantes surdos e ouvintes eram adultos, proficientes em Libras e em português, com formação universitária. A análise semântica foi desenvolvida por meio de grupo focal com adolescentes surdos. Na última etapa, 50 adolescentes surdos, estudantes de escolas públicas do Distrito Federal responderam ao instrumento. A versão adaptada da EMSVA demonstrou boa consistência interna (λ2 = 0,89) na amostra de adolescentes surdos.(AU)

RESUMO

Introduction: Children with special health-care needs have limitations in oral hygiene performance due to their potential motor, sensory, and intellectual disabilities and so are more prone to have compromised oral health. Aim: This study aimed to compare the impact of oral hygiene instructions given via sign language and a validated customized oral health education skit video on oral hygiene status of children with hearing impairment (CHI). Settings and Design: Ethical clearance was obtained from the institutional ethical committee for research activities. The study was carried out across CHI schools of Wardha district, Maharashtra, India. Methodology: Sixty-eight CHI, within the age group of 6-13 years, were divided into two educational intervention groups: customized oral health educational video (Group A) and sign language (Group B). A structured questionnaire was designed to gather information about the routine oral hygiene practices via the Indian Sign Language. Baseline Gingival Index (GI)-S and Plaque Index-S indices were recorded. Based on the group assigned, oral hygiene instructions were given on a daily basis. Reassessment was done after 4 weeks. Statistical Analysis: Unpaired t-tests were performed (P < 0.05) to determine if significant differences exist between the two groups. Results: Postintervention plaque scores between Group A and Group B were 0.12 ± 0.22 and 0.07 ± 0.22, respectively, and the difference between the two was statistically insignificant (P = 0.330). For GI, scores in Group A and Group B were 0.03 ± 0.12 and 0.04 ± 0.12, respectively, and the difference was statistically insignificant (P = 0.669). Conclusion: Both sign language and the validated customized video modeling have been proved to be positively influencing the oral hygiene status of CHI equivalently.

RESUMO

El objetivo de este trabajo es determinar si las personas sordas usuarias de lengua de señas mexicana (LSM) activan la LSM en la lectura de palabras escritas en español. Se usaron pares de palabras semánticamente relacionadas y semánticamente no relacionadas, divididas a su vez 2subgrupos, fonológicamente relacionadas y fonológicamente no relacionadas en LSM. Los participantes respondieron más rápido a las palabras semánticamente y fonológicamente relacionadas, mientras que, por el contrario, respondieron más lento en las palabras semánticamente no relacionadas que sí estaban fonológicamente relacionadas. Los resultados sugieren un efecto de facilitación e interferencia, respectivamente, dado por la activación de la LSM


The goal of this study was to determine whether deaf bilingual MSL-Spanish adults activate their signed language when reading words in Spanish. Participants were Mexican Deaf signers whose dominant language was Mexican Sign Language and who had a basic Spanish written proficiency. Two main conditions were examined for word groups: semantically related and non-related words. They were also distinguished by hand "phonology": related and unrelated configurations. The written words were presented in a reaction-time task in which participants were asked to identify whether the words belonged to similar categories. Mean reaction times were faster for semantically and phonologically related and slower for semantically unrelated but phonologically related pairs. Results show that the structure of the word in Sign language is activated when reading words in Spanish

RESUMO

Human activity recognition is an important and difficult topic to study because of the important variability between tasks repeated several times by a subject and between subjects. This work is motivated by providing time-series signal classification and a robust validation and test approaches. This study proposes to classify 60 signs from the American Sign Language based on data provided by the LeapMotion sensor by using different conventional machine learning and deep learning models including a model called DeepConvLSTM that integrates convolutional and recurrent layers with Long-Short Term Memory cells. A kinematic model of the right and left forearm/hand/fingers/thumb is proposed as well as the use of a simple data augmentation technique to improve the generalization of neural networks. DeepConvLSTM and convolutional neural network demonstrated the highest accuracy compared to other models with 91.1 (3.8) and 89.3 (4.0) % respectively compared to the recurrent neural network or multi-layer perceptron. Integrating convolutional layers in a deep learning model seems to be an appropriate solution for sign language recognition with depth sensors data.
