Background: several authors have pointed to the urgent need of researches and actions involving teachers, in the school environment, that have a preventive and vocal health promotion character with the purpose of improving work conditions. Aim: to analyze the vocal complaints, laryngeal symptoms, vocal habits and vocal profile of teachers of a public school before and after their participation in voice workshops. Method: the study was divided in different steps: 1st step -closed interview, larynx and perceptive-auditory assessment in which 42 teachers were evaluated; 2nd step -voice workshops; 3rd step -perceptive-auditory reassessment in which 13 teachers were evaluated. Results: 73% of the subjects presented vocal complaints; 57.14% presented mild to moderate hoarseness, 78.57% presented breathiness and 52.38% vocal tension. Evaluation of the larynx indicated that 75.86% of the subjects presented glottal gaps and 34.48% mucous thickening. After the voice workshops a significant difference was observed in the level of vocal tension, both in the analysis of the /e/ vowel and in the analysis of Spontaneous Speech (p = 0.0277 for p > 0.05 for both). Improvement was observed in vocal care and in the understanding of intervening and determinant factors for vocal alterations, which are present in the teaching environment. Conclusion: health actions, such as voice workshops, are important to trigger changes in the work environment as well as in the health of teachers. Key Words: Voice; Teacher; Occupational Health; Health Promotion. ResumoTema: vários autores têm apontado a urgência de se intensificar pesquisas e ações voltadas ao professor, na escola, de caráter preventivo e de promoção de saúde vocal, que se volta para a melhoria das condições de trabalho e do ambiente no qual ocorre a docência. Assim sendo, o objetivo deste estudo foi: analisar as queixas, os sintomas laríngeos, hábitos relacionados ao desempenho vocal e o tipo de voz de professores de uma escola da rede pública de ensino antes e após a participação em grupos de vivência de voz. Método: o estudo foi dividido em etapas com professores de uma escola pública: 1ª Etapa: entrevista, avaliação laringológica e perceptivo-auditiva da qual participaram 42 professores; 2ª Etapa: grupos de vivência de voz e 3ª Etapa: reavaliação perceptivo-auditiva -das quais participaram 13 professores. Resultados: 73% dos sujeitos apresentaram queixas vocais; 57,14% apresentaram rouquidão de grau leve e moderado, 78,57% apresentaram soprosidade e 52,38% apresentaram tensão na voz. Ao exame laringológico, 75,86% apresentaram fendas glóticas e 34,48% espessamento mucoso. Após a vivência de voz houve diferença significativa no grau de tensão, tanto na análise da vogal /e/ como na análise da fala espontânea (p = 0,0277 para p > 0,05 para ambas). Houve melhora dos cuidados com a voz e a compreensão dos fatores intervenientes e determinantes das alterações vocais, presentes nas condições e organização do trabalho docente. Conclusão: ações educativas processuais, como os g...

Abstract-First a new high performance robust latch (referred to as HiPeR latch) is presented, that is insensitive to transient faults affecting its internal and output nodes by design, independently of the size of its transistors. Then, a modified version of the HiPeR latch (referred as HiPeR-CG) is proposed, that is suitable to be used together with clock gating. Both proposed latches are faster than the latches most recently presented in the literature, while providing better or comparable robustness to transient faults, at comparable or lower costs in terms of area and power, respectively. Therefore, thanks to the good tradeoffs in terms of performance, robustness and cost, our proposed latches are particularly suitable to be adopted on critical paths.
