A hearing report from Brazil

The past several decades, the need for hearing health services is still great, especially in the northeast, the Amazonian, and the southern regions Brazil, officially Federative Republic of Brazil, is the largest Portuguese-speaking country, and the fifth largest country in the world by population and by land. The vast land not only brings rich natural resources but also large varieties of exotic vegetation and wildlife. One hundred and ninety-three million inhabitants live in five geographical regions with diverse cultural practices influenced by immigrants from Italy, Spain, Japan, Germany, and other countries. Brazilian people generally are warm-hearted, very welcoming, and resilient. They are optimistic and creative despite having encountered many economic downturns and political challenges throughout history. A bachelor's degree is the entry level for the profession. As only 19 percent of the population aged 18–24 years have access to higher education, the competition for admissions is fierce, especially in government institutions. High school students need to pass tests of general knowledge in a national examination and a university-specific examination. Government educational institutions offer good education without charging tuition. The majority of scientific papers are also produced by scholars working in government institutions. Private institutions are generally ranked lower in academic rigor (Behlau and Gasparini, 2006), except for a few top-ranking institutions. The fields of speech-language pathology and audiology are marked by rapid changes in recent years. Currently, there are 104 undergraduate programs recognized by the Ministry of Education and distributed in all but three federal states of Brazil.

Influence of Particle Size, Applied Compression, and Substratum Material on Particle-Surface Adhesion Force Using the Centrifuge Technique

The centrifuge technique was used to investigate the influence of particle size, applied compression, and substrate material (stainless steel, glass, Teflon, and poly(vinyl chloride)) on particle-surface adhesion force. For this purpose, phosphatic rock (rho(p) = 3090 kg/m(3)) and manioc starch particles (rho(p) = 1480 kg/m(3)) were used as test particles. A microcentrifuge that reached a maximum rotation speed of 14 000 rpm and which contained specially designed centrifuge tubes was used in the adhesion force measurements. The curves showed that the adhesion force profile followed a normal log distribution. The adhesion force increased linearly with particle size and with the increase of each increment of compression force. The manioc starch particles presented greater adhesion forces than the phosphatic rock particles for all particle sizes studied. The glass substrate showed a higher adherence than the other materials, probably due to its smoother topographic surface roughness in relation to the other substrata.

A postura educativa de O Tico-Tico: uma análise da primeira revista brasileira de histórias em quadrinhos

Este trabalho discute a produção da revista O Tico-Tico, publicação de quadrinhos de mais onga duração no Brasil. A revista, que teria completado 100 anos em outubro de 2005, caracterizou-se por uma postura didático-pedagógica e pela disseminação de produtos quadrinhísticos genuinamente nacionais, dando oportunidade para a atuação de dezenas de desenhistas brasileiros e propiciando o aparecimento de diversos personagens de histórias em quadrinhos. Na década de 1960, desgastada pelo tempo e sofrendo a concorrência da televisão, a revista encerrou suas atividades, ficando na lembrança de seus leitores por sua abnegação a um modelo de educação para a infância que privilegiava o civismo, os bons costumes e a religiosidade

Alimentação hospitalar: proposições para a qualificação do Serviço de Alimentação e Nutrição, avaliadas pela comunidade científica

The scope of this paper is to validate proposals used to qualify hospital food by the Brazilian scientific community. An electronic questionnaire was applied to clinical nutrition professionals registered on the Lattes Platform (Brazilian database of institutions and researchers' curricula in the areas of Science and Technology). The questionnaire incorporated a Likert scale and had spaces for comments. The themes dealt with patient participation, the nutritional and sensory quality of hospital diets, and planning and goals of the Hospital Food and Nutrition Service (HFNS). The questionnaire also asked for the top five priorities for a HFNS. Proposals with total or partial adherence equal to or greater than 70% were considered to be approved. All proposals had total adherence equal to or greater than 70%. The proposal that had minimal adherence (70%) was the one that proposed that nutritional intervention must be arranged by mutual agreement with the patient. The proposal that had maximal adherence (93%) was the one advocating that there must be statistical control on diets prescribed by the HFNS. The most cited priorities referred to infrastructure and training of human resources (40%), the quality of hospital food (27%) and the nutritional status of the patient.

Voice disorders in children and its relationship with auditory, acoustic and vocal behavior parameters

Objective: Parameters to distinguish normal from deviant voices in early childhood have not been established. The current study sought to auditorily and acoustically characterize voices of children, and to study the relationship between vocal behavior reported by teachers and the presence of vocal aberrations. Methods: One hundred children between four and 6 years and 11 months, who attended early childhood educational institutions, were included. The sample comprised 50 children with normal voices (NVG) and 50 with deviant voices (DVG) matched by gender and age. All participants were submitted to auditory and acoustic analysis of vocal quality and had their vocal behaviors assessed by teachers through a specific protocol. Results: DVG had a higher incidence of breathiness (p < 0.001) and roughness (p < 0.001), but not vocal strain (p = 0.546), which was similar in both groups. The average F-0 was lower in the DVG and a higher noise component was observed in this group as well. Regarding the protocol used "Aspects Related to Phonotrauma - Children's Protocol", higher means were observed for children from DVG in all analyzed aspects and also on the overall means (DVG = 2.15; NVG = 1.12, p < 0.001). In NVG, a higher incidence of vocal behavior without alterations or with discrete alterations was observed, whereas a higher incidence of moderate, severe or extreme alterations of vocal behavior was observed in DVG. Conclusions: Perceptual assessment of voice, vocal acoustic parameters (F-0, noise and GNE), and aspects related to vocal trauma and vocal behavior differentiated the groups of children with normal voice and deviant voice.

Panorama atual dos repositórios institucionais das instituições de ensino superior no Brasil

O cenário atual de repositórios digitais mundialmente distribuídos estimula estudos diversificados com os quais esse trabalho visa contribuir, objetivando um levantamento dos repositórios de instituições de ensino superior no Brasil, verificando a eficácia de uma ferramenta experimental no tratamento e análise dos dados e usando como fontes os diretórios Registry of Open Access Repositories (ROAR), Directory of Open Access Repositories (OpenDOAR), Diretório Luso-Brasileiro de Periódicos e Repositórios de Acesso Livre e a lista L_repositories. A ferramenta experimental Google Fusion Tables foi aplicada nos dados dos repositórios institucionais pesquisados, categorizando suas principais características: Instituição mantenedora, Natureza da instituição, Local, Região geográfica, Software adotado e sua versão, adoção do padrão Dublin Core e quantidade de trabalhos disponibilizados na data do estudo. Foram identificados 49 repositórios que em agosto de 2013 disponibilizavam 396.881 itens, sendo as instituições federais as com maior povoamento e o repositório LUME o primeiro em volume de itens; a região Sudeste com o maior número de repositórios e volume de itens disponibilizados; o DSpace o software predominante, com maior utilização da versão 1.6.2 e o padrão de metadados Dublin Core em todas as aplicações desse software. Este estudo comprovou a eficácia e utilidade do FusionTables, permitindo caracterizar o panorama atual de repositórios de instituições de ensino superior no Brasil. Os resultados foram disponibilizados em um Catálogo de Repositórios de Instituições de Ensino Superior no Brasil e um Mapa interativo dos Repositórios de Instituições de Ensino Superior no Brasil.
