A redução de vogais no português: estudo de uma amostra do PE em comparação com o PB

This study aims to verify the reduction phenomenon and/or disappearance of vowels, especially unstressed vowels in PE compared to the PB, obtained by analysis of the recording of an oral reading sample of the Mar Português poem, by Fernando Pessoa, made by informants of the two variants. The noticeable difference in pronunciation of the informants, with any possibility of reaching up to no understanding of European pronunciation by Brazilian speakers motivated the development of an experiment that allowed us to compare the duration of vowels produced in the two variants. By isolating and measuring the vowels at Praat audio analysis program, this study was to confirm the reduction and, in extreme cases, the disappearance of unstressed vowels in PE, a phenomenon described in Mateus and D'Andrade (2000)

Prevalence and antifungal susceptibility of Candida parapsilosis complex isolates collected from oral cavities of HIV-infected individuals

At present, few data are available on the prevalence and antifungal susceptibility of Candida parapsilosis complex isolates from HIV-infected individuals. The C. parapsilosis complex comprises three species, C. parapsilosis sensu stricto, C. metapsilosis and C. orthopsilosis. Fifteen of 318 Candida isolates were identified as members of the C. parapsilosis complex by PCR and restriction fragment length polymorphism (RFLP). The prevalence of C. parapsilosis complex isolates was 4.7 %, 2.2 % being identified as C. parapsilosis sensu stricto and 2.5% as C. metapsilosis, while no C. orthopsilosis was isolated. This is believed to be the first study that has identified isolates of C. metapsilosis obtained from the oral cavity of HIV-infected individuals. Antifungal susceptibility tests indicated that all the isolates were susceptible to amphotericin B (AMB), fluconazole (FLC), ketoconazole (KTC), itraconazole (ITC), voriconazole (VRC) and caspofungin (CASPO). Although isolates of C. parapsilosis sensu stricto and C. metapsilosis were susceptible to FLC, isolates of C. metapsilosis showed a tendency for higher MICs (>= 1.0 mu g ml(-1)). Based upon the frequency of candidiasis and the fact that certain isolates of the C. parapsilosis complex respond differently to FLC therapy, our data may be of therapeutic relevance with respect to susceptibility and potential resistance to specific antifungal agents. Our data suggest that C. metapsilosis can be a human commensal; its importance as a pathogen has yet to be confirmed.

Educação em saúde: Efeito de um método de auto-instruçáo sobre os níveis de higiene oral em escolares

Objective: To identify the effect of a self-instructive method (comic strip), applied with distinct approaches and evaluated over two periods, on the oral health of schoolchildren. Method: The sample comprised 2nd year elementary schoolchildren chosen randomly and divided into four groups: a control group (G1) which received no material, a reading group (G2), which was given the comic strip and read it in the classroom, a discussion group (G3), who received the comic strip, which was read out loud in the classroom and discussed, and a complete group (G4), which received the comic strip and which, after reading it, was asked to rewrite the story. O'Leary's plaque index was used as an evaluation instrument, measured immediately prior to application of the program and again 30 days later. The plaque index measured after and 30 days was compared, in each group, using the Wilcoxon test. The plaque index of the diferents groups was compared using the Kruskal-Walis test, in two moments diferents. The significance level was 5%. Results: The results of the evaluation revealed a statistically significant reduction (p<0.05) of the plaque index presented between the two periods in the four groups studied here. However, this reduction was considerably greater in the discussion and complete groups. Conclusion: The use of the self-instruction method associated with work on its content, as occurred in the discussion and complete groups, led to a better understanding of the subject matter, resulting in a higher reduction of plaque indices.

Outras Inquisições: apontamentos sobre sistematizações, Hermenêutica e História Oral

The starting point of this paper are some avaliable analyses and characterizations about the academic production in History of Mathematics Education in Brazil. A specific reading of such readings – an hermeneutical approach of those avaliable reviews – allows us to put the focus on some features of Oral History thought as a qualitative methodological approach to researches in Mathematics Education.
