A propósito dos parâmetros curriculares nacionais e sua relação com o ethos cultural hodierno

The text focuses on the relation between the Law of Directives and Bases of National Education, as well as its deployment in the National Curriculum, and contemporary culture in three aspects: the predominantly naive about the relation between technological development / education, the translation rhetoric about family’s institution as a partner of educational practices, and finally, the use of systems theory applied to the context of politicaleducational diagnosis. Results from a larger research project in progress titled "Cultural Industry and formative processes: Subsidies to reflect the new educational demmands”.

Contribuições da epistemologia genética para a construção do conhecimento na educação infantil

The kindergarten has as main objective the development of the child from zero to five years in their physical, emotional, cognitive and social domains. This is also the goal of the Centers for Children Living from the Universidade Estadual Paulista (UNESP) that caters to children of teachers, technical and administrative staff and students. In this work we report some of the action of the Technical Commission of the CCIs with reflections on the construction of children's knowledge through observations of the CCIs in different campuses of Unesp, conducted through technical visits. As a theoretical contribution we adopt the Genetic Epistemology of Jean Piaget. Partial results show that, although there are efforts to understand and assist the process of constructing knowledge of children, many challenges remain to be overcome in the realization of an excellent service to children.

Quantified power Doppler as a predictor of delayed graft function after renal transplantation

No safe ultrasound (US) parameters have been established to differentiate the causes of graft dysfunction.To define US parameters and identify the predictors of normal graft evolution, delayed graft function (DGF), and rejection at the early period after kidney transplantation.Between June 2012 and August 2013, 79 renal transplant recipients underwent US examination 1-3 days posttransplantation. Resistive index (RI), power Doppler (PD), and RI + PD (quantified PD) were assessed. Patients were allocated into three groups: normal graft evolution, DGF, and rejection.Resistive index of upper and middle segments and PD were higher in the DGF group than in the normal group. ROC curve analysis revealed that RI + PD was the index that best correlated with DGF (cutoff = 0.84). In the high RI + PD group, time to renal function recovery (6.33 +/- A 6.5 days) and number of dialysis sessions (2.81 +/- A 2.8) were greater than in the low RI + PD group (2.11 +/- A 5.3 days and 0.69 +/- A 1.5 sessions, respectively), p = 0.0001. Multivariate analysis showed that high donor final creatinine with a relative risk (RR) of 19.7 (2.01-184.7, p = 0.009) and older donor age (RR = 1.17 (1.04-1.32), p = 0.007) correlated with risk DGF.Quantified PD (RI + PD) was the best DGF predictor. PD quantification has not been previously reported .

Maxillary sinus lift without grafting, and simultaneous implant placement: a prospective clinical study with a 51-month follow-up

A prospective clinical study of maxillary sinus lift procedures in the posterior region of the maxilla, using only blood clot as filling material, was conducted. Seventeen patients underwent a maxillary sinus lift procedure; 20 maxillary sinus regions were operated on and a total of 25 implants were placed. The sinus mucosa was lifted together with the anterior wall of the osteotomized maxilla and supported by the implants placed. Computed tomography (CT) scans were obtained immediately postoperative (T-initial) and at 3 (T-1) and 51(T-2) months postoperative for the measurement of linear bone height and bone density (by grey tones). Only one implant was lost in the first stage (96% success). After dental prosthesis placement and during up to 51 months of follow-up, no implant was lost (100% success, second stage). The difference in mean bone height between T-initial (5.94 mm) and T-1 (13.14 mm), and between T-initial and T-2 (11.57 mm), was statistically significant (both P < 0.001); comparison between T-1 and T-2 also presented a statistical difference (P < 0.001). Bone density had increased at the end of the period analyzed, but this was not statistically significant (P > 0.05). Thus, the maxillary sinus lift technique with immediate implant placement, filling with blood clot only, may be performed with a high success rate.

Systemic lupus erythematous and clinical outcomes in peritoneal dialysis

Background: The prevalence of systemic lupus erythematous (SLE) patients requiring renal replacement therapy (RRT) is increasing but data on clinical outcomes are scarce. Interestingly, data on technique failure and peritoneal-dialysis (PD)-related infections are rarer, despite SLE patients being considered at high risk for infections. The aim of our study is to compare clinical outcomes of SLE patients on PD in a large PD cohort. Methods: We conducted a nationwide prospective observational study from the BRAZPD II cohort. For this study we identified all patients on PD for greater than 90 days. Within that subset, all those with SLE as primary renal disease were matched with PD patients without SLE for comparison of clinical outcomes, namely: patient mortality, technique survival and time to first peritonitis, then were analyzed taking into account the presence of competing risks. Results: Out of a total of 9907 patients, we identified 102 SLE patients incident in PD and with more than 90 days on PD. After matching the groups consisted of 92 patients with SLE and 340 matched controls. Mean age was 46.9 +/- 16.8 years, 77.3% were females and 58.1% were Caucasians. After adjustments SLE sub-hazard distribution ratio for mortality was 1.06 (CI 95% 0.55-2.05), for technique failure was 1.01 (CI 95% 0.54-1.91) and for time to first peritonitis episode was 1.40 (CI 95% 0.92-2.11). The probability for occurrence of competing risks in all three outcomes was similar between groups. Conclusion: PD therapy was shown to be a safe and equally successful therapy for SLE patients compared to matched non-SLE patients.

Computer graphics applied to anatomy: a study of two bio-cad modeling methods on finite element analysis of human edentulous hemi-mandible

Modeling is a step to perform a finite element analysis. Different methods of model construction are reported in literature, as the Bio-CAD modeling. The purpose of this study was to perform a model evaluation and application using two methods of Bio-CAD modeling from human edentulous hemi-mandible on the finite element analysis. From CT scans of dried human skull was reconstructed a stereolithographic model. Two methods of modeling were performed: STL conversion approach (Model 1) associated to STL simplification and reverse engineering approach (Model 2). For finite element analysis was used the action of lateral pterygoid muscle as loading condition to assess total displacement (D), equivalent von-Mises stress (VM) and maximum principal stress (MP). Two models presented differences on the geometry regarding surface number (1834 (model 1); 282 (model 2)). Were observed differences in finite element mesh regarding element number (30428 nodes/16683 elements (model 1); 15801 nodes/8410 elements (model 2). D, VM and MP stress areas presented similar distribution in two models. The values were different regarding maximum and minimum values of D (ranging 0-0.511 mm (model 1) and 0-0.544 mm (model 2), VM stress (6.36E-04-11.4 MPa (model 1) and 2.15E-04-14.7 MPa (model 2) and MP stress (-1.43-9.14 MPa (model 1) and -1.2-11.6 MPa (model 2). From two methods of Bio-CAD modeling, the reverse engineering presented better anatomical representation compared to the STL conversion approach. The models presented differences in the finite element mesh, total displacement and stress distribution.

Chemical and rheological properties of exopolysaccharides produced by four isolates of rhizobia

The rheological, physicochemical properties, emulsification and stability of exopolysaccharides (EPSs) from four rhizobia isolates (LBMP-C01, LBMP-C02, LBMP-C03 and LBMP-C04) were studied. The EPS yields of isolates under these experimental conditions were in the range of 1.5-6.63gL(-1). The LBMP-C04 isolate, which presented the highest EPS production (6.63gL(-1)), was isolated from Arachis pintoi and was identified as a Rhizobium sp. strain that could be explored as a possible potential source for the production of extracellular heteropolysaccharides. All polymers showed a pseudoplastic non-Newtonian fluid behavior or shear thinning property in aqueous solutions. Among the four EPS tested against hydrocarbons, EPS LBMP-C01 was found to be more effective against hexane, olive and soybean oils (89.94%, 82.75% and 81.15%, respectively). Importantly, we found that changes in pH (2-11) and salinity (0-30%) influenced the emulsification of diesel oil by the EPSs. EPSLBMP-C04 presented optimal emulsification capacity at pH 10 (E24=53%) and 30% salinity (E24=27%). These findings contribute to the understanding of the influence of the chemical composition, physical properties and biotechnology applications of rhizobial EPS solutions their bioemulsifying properties.

Aplicação de modelos hidrológicos para avaliação de reservatórios de retenção e detenção combinados à obra de recuperação do canal de macrodrenagem no controle de cheias em uma bacia hidrográfica urbanizada

The aim of this paper was to evaluate the effect of retention and detention reservoirs along with the regulation in channel flow upgrade on flood for an urban watershed located at Rio Claro, SP. For this purpose, modeling and simulation techniques were applied for runoff determination and its propagation in channel. The Soil Conservation Service – SCS hydrologic model as well as Pulz and non-linear Muskingum-Cunge model were used. The software IPHS1 was applied on simulations. The results pointed out that the combination of retention increasing and detention reservoir implementation (120,000 m3, corresponding to 1.5% of the watershed area) with the streamflow upgrade (n decreasing from 0,04 to 0,02) can minimize the flood on the investigated Servidão watershed. Further, after the proposed intervention, the flood was eliminated for the investigated times of recurrence: 5, 20, 50 and 100 years. The prognostic indicated that the available area occupation had a minor effect on flow increasing due to the observed high urbanization.

A questão da experiência estética nos debates de epistemologia da comunicação

In the outline of communication epistemology, the article discusses the fluid and complex delimitations of the field of social communication and its intersections with the world of aesthetics. It includes the question of aesthetic experience and its presence in the epistemological debates on communication in Brazil. It tries to identify possible contributions of the phenomenology of aesthetic experience, based upon the teachings of Mikel Dufrenne and the theoretical references proposed by John Dewey, Paul Valéry, Luigi Pareyson and Jacques Rancière, to the studies on communication. To contextualize the articulations between communication and aesthetics in the debates developed in the Working Group on Communication Epistemology, the article briefly explores the works that discussed that intersection over the last ten years.
