Atenção, consciência e prática pedagógica: um estudo de suas interconexões

This thesis entitled, Attention, Consciousness and Practice of Teaching: A Study of its Interconnects, argues about a relationship between development of attention and consciousness and its connection to the pedagogical practice developed in a public elementary school in Natal city, Rio Grande do Norte state. The research school is located in the south of the city. School activities are developed according with the political pedagogical project. The group investigated was 25 students aged between 8-12 years of the fourth grade. The students of the research are residents of Ponta Negra village, Pirangi and Neópolis districts. The research was effected by three teachers however, the purpose of this thesis was to investigate the relationship between the development of attention and awareness and the pedagogical practice of one of the teachers who participated in the research, and more specifically understand the psychic procedures involved in the development of attention and awareness; enabling conditions for the realization of an educational action that enables the development in terms of focused attention and states of consciousness of students, analyzing their interrelations. Therefore, it was used as methodology the collaborative research by providing elements for research as strategy of formation and development, the coproduction of knowledge, and the change of educational practice through reflective processes effected through the collaboration and critical reflection among participants. For empirical construction, it was used the following procedural elements: meeting, planning, diagnosis of attention and awareness, reflective period studies, collaborative observation and reflection sessions with the participant teachers and the students. The diagnosis of attention was effected through a game and its elaboration was based on the study proposed by Luria (1991). The purpose of the game was to apprehend the stage where students were in relation of a development attention. Concerning the diagnosis of consciousness, it was taken as reference studies by Burlatski (1987), Pinto (1960a, 1960b), Rubinstien (1973), Leontiev (1978) and others studies discussing this topic. As a method of analysis, it was resorted to the dialectical historical materialism, the ability to identify, analyze and explain those contradictions generated in the process. In the analysis procedures were prepared some categories as well as, were used categories by other authors with the purpose of understanding the critical reflective process collaborative evidencing the formation of concepts and pedagogical practice of the participants, and the analysis of a practical pedagogical of a teacher and her relationships with the development of the psychic process and functions of students, in other words, attention and awareness. Regarding the reflective process were used the categories: technical reflection, critical reflection and practical reflection (LIBERALI, 2008). Concerning the analysis of the concepts were used the categories: description, characterization, definition and conceptualization (FERREIRA, 2003). And for critical collaboration were the categories: critical collaboration, uncritical, technique and practice. In pedagogical practice, were used categories: repetitive practice teaching, heterogeneous and reflexive critical (SOUZA, 2010). During the collaborative observation was evident predominance of heterogeneous practice, because the main participant teacher searches for immediate solution to the situations problem, as well as reflection moments, is the technical arrangement, practice, critical, as well as concern in interacting with students, the qualitative changes, deep knowledge, renewal and transformation of the teaching activity. In this process, the collaborative reflection proved to be an effective strategy for developing awareness of students, because through reflection sessions, the students were able to understand that learning is a building process and that it necessary to be careful for their development

Serviço de atendimento móvel de urgência (SAMU) e a assistência às urgências psiquiátricas

The objective of this work which is characterized as an applied research, with a qualitative exploratory approach and has case study character has been the analysis of the conceptions and dealings of health professionals of SAMU in Natal RN about the attendance of psychiatric urgencies. The information was collected between the months of March and April of 2010, by means of semi-structured interviews, performed with 24 health professionals integrating of SAMU-Natal as well as the usage of direct observation technique, performed in the institution's medical regulation room. Both the number of professionals involved in the interviews and the bringing about of the observations, were determined by saturation methods in qualitative research's information collecting. The interviews and observations were transcribed and submitted to contents analysis technique , more specifically, to thematic analysis, which made possible to reach the deepest levels, that go beyond what has simply been manifest in the speech of the interviewed, getting to the relations among the categories and social structures of the issue of the research. Keeping this in mind, three analysis categories have been built, namely: conceptions and concepts of psychiatric urgencies shared by health professionals in SAMU-Natal; attendances to psychiatric urgencies in SAMU-Natal; and the Brazilian Psychiatric Reformation under the view of the SAMU-Natal's health professionals. Reflection about the analyzed information revealed discussions pertaining to the stigma and prejudice on mental illness, and also, pointed out to some hindrances which impair the attendance to individuals in mental suffering in SAMU-Natal. The interviewed health professionals' conceptions on the individual in psychical crisis involve concepts of unpredictability, aggressiveness and risk, stigmatizing elements and historically associated to the social hazard ideology and need for mentally sicks' segregation. The predominance of these conceptions, seen in health professionals speech, had identifiable reflexes on assistance to psychiatric demands performed by SAMU-Natal, namely: indiscriminate request for military police's presence during psychic crisis intervention, neglect about occasions that involve mental health patients, as well as repetitive assisting practice directed on physical contention, and transportation to psychiatric hospital. Associated to it, the professionals have shown distorted and reductionist understanding about Brazilian Psychiatric Reformation, and, in the majority, haven't lent credibility to present model of attention to mental health, based on psycho-social treatment, pointing their speech to a need for psychiatric patient's internment. In this sense, we notice that the hospital-centered and excluding model conceived by classical psychiatry still remains alive in these health professionals' mentality as a reference to psychiatric urgency's assistance. Therefore, the research revealed a sequence of elements, that make us think about the challenges that health sector and society must face to realize Brazilian Psychiatric Reformation's principles and guidelines

Painéis-sanduíche com núcleo de EPS reciclado: metodologia de execução e determinação de propriedades termofísicas

New materials made from industrial wastes have been studied as an alternative to traditional fabrication processes in building and civil engineering. These materials are produced considering some issues like: cost, efficiency and reduction of nvironmental damage. Specifically in cases of materials destined to dwellings in low latitude regions, like Brazilian Northeast, efficiency is related to mechanical and thermal resistance. Thus, when thermal insulation and energetic efficiency are aimed, it s important to increase thermal resistance without depletion of mechanical properties. This research was conducted on a construction element made of two plates of cement mortar, interspersed with a plate of recycled expanded polystyrene (EPS). This component, widely known as sandwich-panel, is commonly manufactured with commercial EPS whose substitution was proposed in this study. For this purpose it was applied a detailed methodology that defines parameters to a rational batching of the elements that constitute the nucleus. Samples of recycled EPS were made in two different values of apparent specific mass (ρ = 65 kg/m³; ρ = 130 kg/m³) and submitted to the Quick-Line 30TM that is a thermophysical properties analyzer. Based on the results of thermal conductivity, thermal capacity and thermal diffusivity obtained, it was possible to assure that recycled EPS has thermal insulation characteristics that qualify it to replace commercial EPS in building and civil engineering industry

Diffusion of Interstitial Elements in Ti Alloys used as Biomaterials

Titanium alloys are excellent implant materials for orthopedic applications due to their desirable properties, such as good corrosion resistance, low elasticity modulus, and excellent biocompatibility. The presence of interstitial elements (such as oxygen and nitrogen) causes strong changes in the material's mechanical properties, mainly in its elastic properties. Study of the interaction among interstitial elements present in metals began with Snoek's postulate, that a stress-induced ordering of interstitials gives rise to a peak in the mechanical relaxation (internal friction) spectra. In the mechanical relaxation spectra, each species of interstitial solute atom gives rise to a distinct Snoek's peak, whose temperature and position depend on the measurement frequency. This effect is very interesting because its peculiar parameters are directly related to the diffusion coefficient (D) for the interstitial solute. This paper presents a study of diffusion of heavy interstitial elements in Ti-35Nb-7Zr-5Ta alloys using mechanical spectroscopy. Pre-exponential factors and activation energies are calculated for oxygen and nitrogen in theses alloys.

Prolapse-free relativistic Gaussian basis sets for the superheavy elements up to Uuo (Z=118) and Lr (Z=103)

Prolapse-free basis sets suitable for four-component relativistic quantum chemical calculations are presented for the superheavy elements UP to (118)Uuo ((104)Rf, (105)Db, (106)Sg, (107)Bh, (108)Hs, (109)Mt, (110)Ds, (111)Rg, (112)Uub, (113)Uut, (114)Uuq, (115)Uup, (116)Uuh, (117)Uus, (118)Uuo) and Lr-103. These basis sets were optimized by minimizing the absolute values of the energy difference between the Dirac-Fock-Roothaan total energy and the corresponding numerical value at a milli-Hartree order of magnitude, resulting in a good balance between cost and accuracy. Parameters for generating exponents and new numerical data for some superheavy elements are also presented. (c) 2007 Elsevier B.V. All rights reserved.

A mixture theory based method for three-dimensional modeling of reinforce concrete members with embedded crack finite elements

The paper presents a methodology to model three-dimensional reinforced concrete members by means of embedded discontinuity elements based on the Continuum Strong Discontinuous Approach (CSDA). Mixture theory concepts are used to model reinforced concrete as a 31) composite material constituted of concrete with long fibers (rebars) bundles oriented in different directions embedded in it. The effects of the rebars are modeled by phenomenological constitutive models devised to reproduce the axial non-linear behavior, as well as the bond-slip and dowel action. The paper presents the constitutive models assumed for the components and the compatibility conditions chosen to constitute the composite. Numerical analyses of existing experimental reinforced concrete members are presented, illustrating the applicability of the proposed methodology.

Corona Discharge Model for Transmission Lines by Lumped Elements

This paper shows the insertion of corona effect in a transmission line model based on lumped elements. The development is performed considering a frequency-dependent line representation by cascade of pi sections and state equations. Hence, the detailed profile of currents and voltages along the line, described from a non-homogeneous system of differential equations, can be obtained directly in time domain applying numerical or analytic solution integration methods. The corona discharge model is also based on lumped elements and is implemented from the well-know Skilling-Umoto Model.

MOTOR NERVE CONDUCTION and REPETITIVE NERVE STIMULATION IN CAPTIVE RING-TAILED COATI (NASUA NASUA)

There are few electrophysiologic studies in wild animals. The aim of this study was to determine normal data for motor nerve conduction studies and repetitive stimulation in sciatic-tibial and ulnar nerves in clinically normal captive coati. Eight adult ring-tailed coatis (Nasua nasua), two females and six males weighing 68 kg, were used. Average nerve conduction velocity was 70.81 m/sec (standard deviation [SD] = 3.98) and 56.93 m/sec (SD = 4.31) for the sciatic-tibial and ulnar nerves, respectively. Repetitive stimulation responses demonstrated minimal variations of the area of the compound muscle action potentials at low (3 Hz) and high (20 Hz) frequencies. The maximal obtained decremental area response was 8%. These normal data of conduction studies may be used in assessing abnormalities for clinical diagnosis. In addition, the obtained normal repetitive stimulation data were similar to dogs and humans and may be used for post- and presynaptic disturbances of the neuromuscular transmission in coatis.
