Equacões preditivas para as pressões respiratórias estáticas máximas de adolescentes brasileiros

Introduction: The reference values and prediction equations for maximal respiratory pressures (MRP) differ significantly between the available studies. This large discrepancy can be attributed to the different methodologies proposed. Although the importance of MRP is widely recognized, there are no Brazilian studies that provide predictive equations and reference values for PRM adolescents. Objectives: The purpose of this study was to provide normal values and propose predictive equations for maximal static respiratory pressures of Brazilian adolescents. Methods: An observational cross-sectional study, which evaluated 182 adolescents of both sexes aged between 12 and 18 years, enrolled in schools of the state and private in the city of Natal / RN. The selection of schools and participants of the study was randomly through a lottery system. The spirometric evaluation was performed through the digital spirometer One Flow FVC prior to the assessment of respiratory muscle strength. The MICs were measured with MVD digital manometer 300. Statistical analysis was performed using the SPSS 17.0 software STATISTICS, assigning the significance level of 5%. The normality of data distribution was verified using the Kolmogorov-Smirnov (KS). The descriptive analysis was expressed as mean and standard deviation. We used one-way ANOVA test to verify the difference of the averages of MRPs between age and gender and comparing the averages of MRPs between levels of physical activity. The test t'Student unpaired compared the averages of MRPs being ages and sexes. The comparison of mean values obtained in this study PRM with the values predicted using the equations mentioned above was relizada by testing paired t'Student. To verify the correlation between the PRM and the independent variables (age, weight, height) was used Pearson correlation test. Levene's test evaluated the homogeneity of variance. To obtain predictive equations analysis was used stepwise multiple linear regression. Results: There was no significant difference in mean age between the PRM. The male adolescents, regardless of age, showed superiority in MRP values when compared to the opposite sex. Weight, height and sex correlated with the PRM. Regression analysis suggested in this study, pointed out that the weight and sex had an influence in MIP and MEP only in relation to sex influenced. The mean for each PRM adolescents classified as very active were superior to those observed in adolescents classified as irregularly active. Conclusion: This study provides reference values and two models of predictive equations for maximal inspiratory and expiratory pressures, and to establish the lower limits of normality that will serve as an indispensable condition for careful evaluation of respiratory muscle strength in Brazilian adolescents

Borges: alegoria, metáfora e morte

This work consists of a discussion, analysis and reading of Borges’stories, in that the problem of interest pronounces to the language, to the speech and the deed, sending them so much to the Literature with relationship to the Philosophy, so much to the statute of the ficcional, with relationship to the of the ontologic. In that optics, it intends to show the Borges deed as warp of the death, of the allegorical and of the metaphorical, in the sense of bringing for the ficcional lines different from the Real, elaborating the speech for besides the statement, reaching the interstic, the silence, the interruptions and the suspension of the representation. In that discursive elaboration, a crossing is pointed in the letter, affected for unspeakable sensations, crossing the processes of memory, imaginary and real, in which the time counting makes to emerge the difference and the repetition. In these if constituting territorial negotioting that they lead the characters to imaginary spaces as possibilities of the real, allowing them executes mobility for desterritory it self and reterritory itself, according to the change forces that show in your threshing. For so much, it is placed as mark a bibliographical research orientated by authors as Maurice Blanchot (2008), Kátia Muricy (1998), João Adolfo Hansen (2006), Susan Sontag (2007), Mário Bruno (2004), Juan Manuel García Ramos (2003), Elizabeth Kübler Ross (2008), Walter Benjamin (1984), Gilles Deleuze (1997; 2006; 2009), Gilles Deleuze and Félix Guattari (1995; 1996; 1997). The theoretical corpus and of discussion, it is constituted to leave of those authors, assisting to the implicit qualitative character in the construction of this thesis. What about to the literary corpus, this is composed by the stories The writing of the God, The two kings and the two labyrinths, The lottery of Babylon, The metaphor, The library of Babel, The mirror and the mask, A theologian in death and The dead man.
