Prática de coordenação pedagógica e concepções acerca da atuação em psicologia escolar: desvendando um contexto, repensando caminhos

Considering the necessary approaches with the quotidian of the pedagogical field mentioned in the recent productions in Psychology about the insertion of psychologists in the school field, the objective of this work was to know and to understand the dynamics of functioning of a team of pedagogical coordination, intending to produce reflections on the possibilities of action in school psychology with these professionals. Our field of research was the Municipal School Teacher Emília Ramos (EMPER), considering its peculiar history, distinguished by a constant effort of achievement of the school success by its pupils. As subject of the study, six pedagogical coordinators participated, who worked at the school in the diurne turns, where regular classrooms of 1º cycle of basic education functioned. As procedures, we use participant observations and open interviews, focusing the activities performed by the coordinators and its possible demands to psychology. We use the analysis of content for the production of results. These results evidenced a work of coordination realized on a structured routine, but flexible, centered around the activity of conduction of groups of studies with the teachers. We grouped the demands to psychology in four thematic groups: diagnosis and attending the pupils; orientation to the families, contribution in the formation of the professionals and clinical listening of the professionals of the school. In this way, it is made clear that, in a context where happens a well articulated and consistent pedagogical work, the possible performance in school psychology is not scrumbled or confused with social and pedagogical practical others which many times takes attendance. With these information, we expect to contribute for the theoretical and practical elaborations, in Psychology and the Pedagogy, compromised with the success of the educative work realized in the public schools

Efect of an educative action on relatives' knowledge about childhood burns at home

O objetivo deste trabalho foi avaliar o efeito de ação educativa sobre o conhecimento de familiares de crianças a respeito de queimaduras em ambiente doméstico. Participaram 40 familiares de crianças menores de quatro anos, divididos igualmente em grupos intervenção e controle. Foram realizadas entrevista inicial, ação educativa com folder de queimaduras e entrevista após uma semana. As respostas foram comparadas, utilizando-se teste estatístico de Fisher. Na primeira entrevista, registrou-se 60 respostas de situações de risco no grupo controle e 62 no grupo intervenção; na segunda, aumentou para 61 e 80 indicações, respectivamente. Na primeira entrevista, 90% dos participantes do grupo controle e 80% do grupo intervenção verbalizaram acreditar que a queimadura infantil pode ser evitada; na segunda, a indicação diminuiu para 84% e aumentou para 100%, respectivamente. Este estudo mostrou a importância da orientação com folder de queimaduras em ambiente doméstico.

Practical considerations of embryo manipulation: Preimplantation genetic typing

In the past years, research in embryo technologies is moving to the establishment of preimplantation genetic typing or also denominated preimplantation genetic diagnosis (PGD). The objectives of these tests are the prevention of genetic diseases transmission and the prediction of phenotypic characteristics, as well as sex determination, genetic disorders and productive and reproductive profiles, prior to the embryo transfer or freezing, during early stages of development. This paper points out the state-of-the-art of PGD, mainly in cattle and discuss the perspectives of multiloci genetic analysis of embryos. (C) 2001 by Elsevier B.V.

Some practical advice on polynomial regression analysis from blocked response surface designs

It is often necessary to run response surface designs in blocks. In this paper the analysis of data from such experiments, using polynomial regression models, is discussed. The definition and estimation of pure error in blocked designs are considered. It is recommended that pure error is estimated by assuming additive block and treatment effects, as this is more consistent with designs without blocking. The recovery of inter-block information using REML analysis is discussed, although it is shown that it has very little impact if thc design is nearly orthogonally blocked. Finally prediction from blocked designs is considered and it is shown that prediction of many quantities of interest is much simpler than prediction of the response itself.

Potentialities and practical limitations of absolute neutron dosimetry using thin films of uranium and thorium applied to the fission track dating

Neutron dosimetry using natural uranium and thorium thin films makes possible that mineral dating by the fission-track method can be accomplished, even when poor thermalized neutron facilities are employed. In this case, the contributions of the fissions of (235)U, (238)U and (232)Th induced by thermal, epithermal and fast neutrons to the population of tracks produced during irradiation are quantified through the combined use of natural uranium and thorium films.If the Th/U ratio of the sample is known, only one irradiation (where the sample and the films of uranium and thorium are present) is necessary to perform the dating. However, if that ratio is unknown, it can be determined through another irradiation where the mineral to be dated and both films are placed inside a cadmium box.Problems related with film manufacturing and calibration are discussed. Special attention is given to the utilization of thin films having very low uranium content. The problems faced suggest that it may be better to substitute these films by uranium doped standard glasses calibrated with thicker uranium films (thickness greater than 1.5 x 10(13) mu m).

Electric measurements with constant current: A practical method for characterizing dielectric films

This article assesses the use of the constant current (CC) method for characterizing dielectric films. The method is based on charging the sample with a constant current (current stress) and measuring the corresponding voltage rise under the closed circuit condition. Our article shows that the CC method is an alternative to the constant voltage stressing method to study the electric properties of nonpolar, ferroelectric, and polar polymers. The method was tested by determining the dielectric constant of polytetrafluoroethylene, and investigating the electric conduction in poly(ethylene terephthalate). For the ferroelectric polymer poly(vinylidene fluoride), it is shown that hysteresis loops and the dependence of the ferroelectric polarization on the electric field can be obtained.

PRACTICAL LAND GRADING BASED ON LEAST SQUARES.

Practical methods for land grading design of a plane surface for rectangular and irregularly shaped fields based on a least squares analysis are presented. The least squares procedure leads to a system of three linear equations with three unknowns for determination of the best-fit plane. The equations can be solved by determinants (Cramer's rule) using a procedure capable of solution by many programmable calculators. The detailed computational process for determining the equation of the plane and a simple method to find the centroid location of an irregular field are also given. An illustrative example and design instructions are included to demonstrate the application of the design procedure.

A practical method for lingual retainer fixation before direct bonding: Clinical suggest

The retention phase is initiated after orthodontic treatment completion to prevent orthodontic relapse. There are several techniques, direct and indirect, available for placing bonded lingual retainers, but none of them is considered as a standard clinical protocol. The best choice should be the association of simplicity and efficiency. This article presents a practical method sequence for fixation of the lingual retainer before direct bonding. © 2009 Elsevier Ltd and the Japanese Orthodontic Society.

A practical approach for biometric authentication based on smartcards

Cryptographic systems are safe. However, the management of cryptographic keys of these systems is a tough task. They are usually protected by the use of password-based authentication mechanisms, which is a weak link on conventional cryptographic systems, as the passwords can be easily copied or stolen. The usage of a biometric approach for releasing the keys is an alternative to the password-based mechanisms. But just like passwords, we need mechanisms to keep the biometrical signal safe. One approach for such mechanism is to use biometrical key cryptography. The cryptographic systems based on the use of biometric characteristics as keys are called biometrical cryptographic systems. This article presents the implementation of Fuzzy Vault, a biometrical cryptographic system written in Java, along with its performance evaluation. Fuzzy Vault was tested on a real application using smartcards.
