Estados emocionais em professores recém-formados: análise contextual

In general, the early career is a period marked by crises. Hubermam (1992) points out that this period is considered by the teacher as one of life's most difficult professional teaching. According to Machado (2004), the physical education worked only in competitive perspective in school, does not contribute to the school to perform its social role. This approach encourages the use of stigmas, labels and prejudices, so common in school, that marginalize even more students from lower classes, and can make the sport of high performance within the school walls create students with low self-esteem and low motivation within other possible disorders . Thus, this study presents the fundamental importance to aid and support to novice teachers, so that they can understand, and address key emotional aspects that interfere in their practice. Thus, our aim was to identify the most recurrent emotional processes in novice teachers identify and also how these emotional states can influence the professional and personal attitudes of these teachers. Through a bibliographic we seek statements, reports and case studies that provide enough material to our analysis and interpretation in order to collaborate with the study area and proceed to proposals that are not unreasonable or tied to the current system. Among the emotional states reported in the literature, we highlight the main, more present and influent in the beginner teacher as listed as follow: Anxiety, Stress, Fear, Shame, Low Self Confidence and Motivation. Considering these states, Damasio (1996) reports that the United Emotional directly influenced the style and efficiency of cognitive processes, in other words, interfere with the performance of teachers in the teaching front. Thus, Machado (2006) points out that the teacher should have a set of techniques and procedures that drive their practice in a manner appropriate to the leading group. Therefore, the knowledge of Psychology of Physical...

Glutamatergic antagonism in the NTS decreases post-inspiratory drive and changes phrenic and sympathetic coupling during chemoreflex activation

For a better understanding of the processing at the nucleus tractus solitarius (NTS) level of the autonomic and respiratory responses to peripheral chemoreceptor activation, herein we evaluated the role of glutamatergic neurotransmission in the intermediate (iNTS) and caudal NTS (cNTS) on baseline respiratory parameters and on chemoreflex-evoked responses using the in situ working heart-brain stem preparation (WHBP). The activities of phrenic (PND), cervical vagus (cVNA), and thoracic sympathetic (tSNA) nerves were recorded before and after bilateral microinjections of kynurenic acid (Kyn, 5 nmol/20 nl) into iNTS, cNTS, or both simultaneously. In WHBP, baseline sympathetic discharge markedly correlated with phrenic bursts (inspiration). However, most of sympathoexcitation elicited by chemoreflex activation occurred during expiration. Kyn microinjected into iNTS or into cNTS decreased the postinspiratory component of cVNA and increased the duration and frequency of PND. Kyn into iNTS produced no changes in sympathoexcitatory and tachypneic responses to peripheral chemoreflex activation, whereas into cNTS, a reduction of the sympathoexcitation, but not of the tachypnea, was observed. The pattern of phrenic and sympathetic coupling during the chemoreflex activation was an inspiratory-related rather than an expiratory-related sympathoexcitation. Kyn simultaneously into iNTS and cNTS produced a greater decrease in postinspiratory component of cVNA and increase in frequency and duration of PND and abolished the respiratory and autonomic responses to chemoreflex activation. The data show that glutamatergic neurotransmission in the iNTS and cNTS plays a tonic role on the baseline respiratory rhythm, contributes to the postinspiratory activity, and is essential to expiratory-related sympathoexcitation observed during chemoreflex activation.

Apoiador matricial: uma possibilidade de promover a interdisciplinaridade entre profissionais da saúde

This study aims to reflect the organization of the mental health services in primary care from a new organizational arrangement to health work, defined as Matrix Support (Campos, 1999), which aims to build technical and educational support in the relationship between health professionals from mental health professionals in the Family Health Strategy. The methodology used in the Matrix Support the “Wheel” method, which is mediated by a supporter who, through questions and reflections, points out possibilities for case discussions, promotes links between the health teams, discusses the concept of link between professionals and users, strengthens the co-responsability for the actions of health and tries to break the logic related with the services organized by referrals. So the wheels when they occur in health services enables the interdisciplinary, and through it, it is expected to talk about the complexity of the phenomena that surround each subject, so that they overcome the dichotomy between individual and collective, social and biological revealing new values to be incorporated into health practices. In front of this analysis that is theoric and conceptual, allied with the experience from a nursisn area professional that worked in this work method, can be concluded that this experience related here, eas strategic for the health care actions for strengthen based on the Unique Health system and Psych Rebuild principles.

Tool condition monitoring of aluminum oxide grinding wheel in dressing operation using acoustic emission and neural networks

The grinding operation gives workpieces their final finish, minimizing surface roughness through the interaction between the abrasive grains of a tool (grinding wheel) and the workpiece. However, excessive grinding wheel wear due to friction renders the tool unsuitable for further use, thus requiring the dressing operation to remove and/or sharpen the cutting edges of the worn grains to render them reusable. The purpose of this study was to monitor the dressing operation using the acoustic emission (AE) signal and statistics derived from this signal, classifying the grinding wheel as sharp or dull by means of artificial neural networks. An aluminum oxide wheel installed on a surface grinding machine, a signal acquisition system, and a single-point dresser were used in the experiments. Tests were performed varying overlap ratios and dressing depths. The root mean square values and two additional statistics were calculated based on the raw AE data. A multilayer perceptron neural network was used with the Levenberg-Marquardt learning algorithm, whose inputs were the aforementioned statistics. The results indicate that this method was successful in classifying the conditions of the grinding wheel in the dressing process, identifying the tool as "sharp''(with cutting capacity) or "dull''(with loss of cutting capacity), thus reducing the time and cost of the operation and minimizing excessive removal of abrasive material from the grinding wheel.

SDRE control strategy applied to a nonlinear robotic including drive motor

A robotic control design considering all the inherent nonlinearities of the robot-engine configuration is developed. The interactions between the robot and joint motor drive mechanism are considered. The proposed control combines two strategies, one feedforward control in order to maintain the system in the desired coordinate, and feedback control system to take the system into a desired coordinate. The feedback control is obtained using State-Dependent Riccati Equation (SDRE). For link positioning two cases are considered. Case I: For control positioning, it is only used motor voltage; Case II: For control positioning, it is used both motor voltage and torque between the links. Simulation results, including parametric uncertainties in control shows the feasibility of the proposed control for the considered system.

Estúdio Ghibli: um aparato sobre as técnicas ilustrativas e filosofia oriental dos principais longas metragens de Hayao Miyazaki

In front of the vast and widespread use of new technology in 3D animation currently, this research aims to give an overview adjacent to major film productions with Studio Ghibli and its main director/animator: Hayao Miyazaki. Showing up as an interesting exception to worldwide success, the Ghibli feature films are made with the predominance of 2D hand-drawn art. Its process dates back to the first animations created in the early twentieth century, though such tools have been “overcome” by big studios like Walt Disney, Pixar and Dreamworks, the works of Miyazaki still get considerable highlight, preferring the pencil and paper than the computer. With the aid of some authors in particular as McCloud and the founders of Anima Mundi, and other theorists of design and subjective philosophy, some analyzes are mapped to better understand the connection between the work of Miyazaki and his contribution to the field of illustration and originality as a whole. The objective is to find the key points of Ghibli animations which will drive new parameters between creativity, illustration and Western and Eastern praxis.

A study on the viability of minimum quantity lubrication with water in grinding of ceramics using a hybrid-bonded diamond wheel

With the currently strict environmental law in present days, researchers and industries are seeking to reduce the amount of cutting fluid used in machining. Minimum quantity lubrication is a potential alternative to reduce environmental impacts and overall process costs. This technique can substantially reduce cutting fluids in grinding, as well as provide better performance in relation to conventional cutting fluid application (abundant fluid flow). The present work aims to test the viability of minimum quantity lubrication (with and without water) in grinding of advanced ceramics, when compared to conventional method (abundant fluid flow). Measured output variables were grinding power, surface roughness, roundness errors and wheel wear, as well as scanning electron micrographs. The results show that minimum quantity lubrication with water (1:1) was superior to conventional lubrication-cooling in terms of surface quality, also reducing wheel wear, when compared to the other methods tested.
