Função do diretor na escola pública paulista: mudanças e permanências

This essay is intended for an analysis of the principal's duties in São Paulo State school, considering the conceptions of Administration specialists, Education professionals and the legal directives pertinent to the State government. It was interesting the procedures of rereading and analyzing of the literature of the area; the survey and analysis of legal documents which, direct or indirectly, concern the principal's duty and the accomplishment, transcription and analysis of half elaborated interviews with administrators and teachers. At the end of this research, it was found some contradictions in the conception of School Administration like it is diffused in different contexts, which anyway reflects the conceptions of the respondents.

School inclusion: analyzing the establishment and organization of a special needs education service in a brazilian municipality

The present research integrates a network of studies called National Monitoring Center for Special Education (NMCSE) which studies the Multi-purpose Feature Rooms (MFRs) in regular schools. We aim to investigate whether the service offered by such rooms, maintained by the Department of Education of the Municipality of Araraquara, in São Paulo State, Brazil, is being successful at supporting the education of children and youth with special needs, pervasive developmental disorders and high skilled/gifted individuals. We have also investigated the limits and possibilities of such rooms concerning the set of services offered to their participants. In order to conduct the present research, we have performed: an interview with the Special Education Program manager from the abovementioned Department of Education; and the analysis of a Training Program that MFRs teachers must take. The training program consists of ten morning and afternoon shift meetings. The analyzed data leads us to conclude that the policy of implementation of MFRs, even in this relatively restricted universe is seen from different perspectives. Some interpretations are still permeated by the clinical model, considering individual action. The challenges observed in the classrooms show that the cooperation among teachers still occur randomly and, among other difficulties raised by them, is the selection of the right placement methods to identify eligible students who will benefit from the Specialized Educational Service (SES). In addition, teaching evaluation was considered fragile, as well as the training and the general requirements demanded in order to achieve the expected results.

Macro- and microstructural organization of the rabbit's celiac-mesenteric ganglion complex (Oryctolagus cuniculus)

The macro- and microstructures of the rabbit celiac-mesenteric ganglion complex are described in 20 young animals. We found ten celiac ganglia, twenty-seven cranial mesenteric ganglia and eleven celiac-mesenteric ganglia. The celiac ganglia had a rectangular shape in nine cases (90%) and a circular one in one case (10%). The cranial mesenteric ganglia presented triangular (66.7%), rectangular (11.1%), L-shape (18.5%) and semilunar (3.7%) arrangements. The celiac-mesenteric ganglia were organized in three patterns: a single left celiac-mesenteric ganglion having a caudal portion (72.7%); celiac-mesenteric ganglia without a caudal portion (18.2%) and a single celiac-mesenteric ganglion with two portions: left and right (9.1%).The microstructure was investigated in nine celiac-mesenteric ganglia. The results showed that the celiac-mesenteric ganglion is actually a ganglion complex constituted of an agglomerate of ganglionic units separated by nerve fibers, capillaries and septa of connective tissue. Using the semi-thin section method we described the cellular organization of the celiac-mesenteric ganglion complex. Inside of each ganglionic unit, there were various cell types: principal ganglion neurons (PGN), glial cells (satellite cells) and SIF cells (small intensely fluorescent cells or small granular cells), which are the cytologic basis for each ganglionic unit of the rabbit's celiac-mesenteric ganglion complex.

Sex-related macrostructural organization of the deer's brachial plexus

We describe the morphological organization of the deer brachial plexus in order to supply data to veterinary neuroclinics and anaesthesiology. The deer (Mazama gouazoubira) brachial plexus is composed of four roots: three cervical (C6, C7 and C8) and one thoracic (T1). Within each sex group, no variations are observed between the left and the right brachial plexus, though sex-related differences are seen especially in its origin. The origin of axillary and radial nerves was: C6, C7, C8 and T1 in males and C8-T1 (radial nerve) and C7, C8 and T1 (axillary nerve) in females; musculocutaneous nerve was: C6-C7 (males) and C8-T1 (females); median and ulnar nerves was: C8-T1 (males) and T1 (females); long thoracic nerve was: C7 (males) and T1 (females); lateral thoracic nerve was: C6, C7, C8 and T1 (males) and T1 (females); thoracodorsal nerve was: C6, C7, C8 and T1 (males) and C8-T1 (females); suprascapular nerve was: C6-C7 (males) and C6 (females) and subscapular nerve was: C6-C7 (males) and C7 (females). This study suggests that in male deer the origin of the brachial plexus is more cranial than in females and the origin of the brachial plexus is slightly more complex in males, i.e. there is an additional number of roots (from one to three). This sexual dimorphism may be related to specific biomechanical functions of the thoracic limb and electrophysiological studies may be needed to shed light on this morphological feature.

Comparative assessment of the organization of the colors of the Vita Classical color pallet by digital images and visual analysis for dental bleaching

New formularizations, techniques and devices have become the dental whitening most safe and with better results. Although this, the verification of the levels whitening is being continued for visual comparison, that is an empirical, subjective method, subject to errors and dependent of the individual interpretation. Normally the result of the whitening is express for the amplitude of displacement between the initial and the final color, being take like reference the tonalities of a scale of color commanded of darkest for more clearly. Although to be the most used scale, the ordinance of the Vita Classical (R) - Vita, according to recommendations of the manufacturer, reveals inadequate for the evaluation of the whitening. From digital images and of algorithm OER (ordinance of the reference scale), especially developed for the ScanWhite (C), the ordinance of the tonalities of the scale Vita Classical (R) was made. For such, the values of the canals of color R, G, and B of medium part average of the crowns was adopted as reference for evaluation. The images had been taken with the camera Sony Cybershoot DSC F828. The results of the computational ordinance had been compared with the sequence proposal for the manufacturer and with the earned one for the visual evaluation, carried through by 10 volunteers, under standardized conditions of illumination. It statistics analyzes demonstrated significant differences between the ordinances.

Evalution of methods for the detection of MRSA in patients of Botucatu Medical School Hospital, São Paulo, Brazil

Oxacillin is the main drug of choice for the treatment of S. aureus infections. However, S. aureus resistance to oxacillin has become a major problem in the recent decades. The study aimed assess the rates of oxacillin resistance in S. aureus samples obtained at the Botucatu Medical School Hospital, UNESP, and to compare phenotypic techniques for the detection of MRSA against the gold standard method (mecA gene detection) in these samples. A total of 102 samples, previously isolated between 2002 and 2006, and kept at the Culture Collection of the Department of Microbiology and Immunology, in the Botucatu Biosciences Institute, UNESP, were included. Oxacillin resistance was assessed by oxacillin and cefoxitin disk diffusion and agar dilution tests, screening tests using Mueller-Hinton agar with 6 mu g/mL of oxacillin and 4% NaCl, E-test, and mecA gene detection. of the samples analyzed, 46 (45.1%) were mecA-positive. Oxacillin disk sensitivity and specificity were 86.9% and 91.1%, respectively. Cefoxitin disk sensitivity and specificity were respectively 91.3% and 91.1%. The screening test with the cefoxitin disk showed almost the same level of sensitivity (91.3%) and specificity (91.1%). With E-test strips, sensitivity was higher (97.8%) and specificity was comparable to that found with the other methods (91.1%). Ninety-three percent of the samples produced beta-lactamase and five of them were mecA-negative. There was a gradual increase in the number of oxacillin-resistant S. aureus samples between 2002 and 2004. However, from 2004 to 2006, the number of resistant samples dropped from 55% of MRSA in 2004, to 45% in 2005 and 34.6% in 2006. The data obtained reveal that, among phenotypic methods, the E-test yielded the best results, with higher sensitivity levels when compared to the other methods. The decreased resistance rate observed over the most recent years may be explained by the rational use of antimicrobial agents associated with good practices in the control of hospital infection, or may be related to the diminished use of oxacillin as a treatment option.
