Caminhos de sobrevivência institucional: a gestão do núcleo de oficinas e artes profissionalizantes laís aderne

The object of this study is the organizational management, particularly the relational processenvironment organization focused on the survival of the space Department of the Arts and Crafts Mestre Raimundo Cardoso linked to the structural arrangement of the Liceu do Paracuri.. Aimed to understand the ways of organizational survival, from the actors' perception of the Center for Arts Career Workshops and Lais Aderne, with investments that discuss the theoretical models of management, institutional theory, cultural organization and institutionalization of public education requirement of the municipal light LDB. (1996) used a qualitative approach with a view to RICHARDSON (1985). The data generated were analyzed based on the technique of content analysis, the thematic type [categorical] Bardin (1977). The results indicate that the institutionalization of the arrangement of the Liceu do Paracuri emerges meet the legal requirement of the autonomy of municipal educational administration under the aegis of sustainable development, quality of life and basic education from the municipal Hélio Gueiros (1993-1996 ). More specifically the Center for Arts and Crafts Laís Aderne, the unit of analysis, the subjects said that this space is designed as a link between the demands of school and community searching through interdisciplinary activities educate and train manpower mainly potter. They did mention the existence of institutional factors (history, culture, habits, values) represent a strong socio-cultural element to the actors belonging to the core that guides behavior and actions of these individuals, fueled by a sense of hope, inclusion of future artisans in culture ceramist. It made a shared management, the existence of a unique work through cultural revival. However, over the course of time, the core is faced with dilemmas of managing transitions mainly regarding governmental, technological beyond endurance by the craftsmen for the optimization of their work. The conclusion - that the paths chosen for the organizational survival of the core meaning and guiding their actions in the systematization of conduct, representations, memories and traditions through habits and choices of consensus, the viewpoint of the actors

A tecitura da ação do coordenador pedagógico da EJA: saberes necessários à mediação do trebalho docente em alfabetização.

Este trabajo tiene su origen en nuestra historia profesional, en la que destacamos el rol mediador de coordinación pedagógica en la (re)construcción de nuestra actuación docente. En este contexto de vida profesional, nace la tesis que discute la problemática de la alfabetización y el rol de la escuela y de sus profesores, mediados por la acción de la coordinación pedagógica, en la construcción de una práctica alfabetizadora de jóvenes y adultos. Investigar qué saberes de la acción pedagógica son requeridos del coordinador pedagógico, en la mediación/ orientación de profesores alfabetizadores de jóvenes y adultos fue el objetivo de este trabajo. Para tejer la investigación fue escogido el abordaje caritativo de la encuesta; como metodología, el estudio de caso y como procedimiento el levantamiento de datos, la observación, el cuestionario, la entrevista y el análisis documental. Aprehendimos de la investigación que, en el desarrollo de su práctica, el coordinador pedagógico moviliza Saberes Específicos y Saberes Transversales de su acción pedagógica. En los saberes específicos, encontramos: Joven y Adulto como sujeto del conocimiento y del aprendizaje; Alfabetización del joven y del adulto: Psicogénesis de la lengua escrita; Ciclo de la acción didáctico-pedagógica. En los saberes transversales, fueron aprendidos: Respetar y se hacerse respetar por profesores y alumnos; Priorizar la dimensión pedagógica en el cotidiano escolar; Mediar la acción docente en las distintas etapas: planeamiento; ejecución y evaluación. La investigación ratifica que el trabajo pedagógico en la escuela debe ser construido en una relación entre profesores y coordinadores. Como resultados, evidenciamos, también, que los coordinadores pedagógicos se encuentran, todavía, sin una identidad profesional, inmersos en muchos quehaceres, sin darse cuenta de lo más importante: la mediación del trabajo docente. El coordinador pedagógico es un profesional que se va construyendo en las prácticas escolares y su identidad profesional aún no está definida como en el campo real de actuación. Basado en los estudios hechos, defendemos la tesis de que, la práctica del coordinador pedagógico en la escuela demanda saberes y quehaceres de acción pedagógica; estos adquieren especificidades en ejercicio de la mediación /orientación de la práctica pedagógica de profesores alfabetizadores de jóvenes y adultos. Aprehendemos como recomendación a los cursos de formación de coordinadores pedagógicos que estos deben proporcionar: Embasamiento teóricometodológico consistente sobre las Ciencias de la Educación; Prácticas Supervisadas de larga duración en la Coordinación Pedagógica de instituciones escolares y no escolares; Experiencia como profesor en sala de clase, de manera preferencial, en el nivel en que el que concluye el curso desea actuar. Fue destacada la importancia del lado humano en el ejercicio de la acción coordinadora, como forma de establecer y alimentar la comunicación con el profesor y, de este modo, coordinadores y profesores comparten la apasionante, pero difícil tarea de educar. Esperamos que el estudio, que destaca saberes necesarios para la práctica del coordinador pedagógico, pueda contribuir para ampliar la discusión del rol de este profesional en la escuela que deseamos pública, democrática y con calidad social.

A ação do coordenador pedagógico e as suas contribuições a vivência compreensiva sob a perspectiva conscienciológica

This work is based on a reflection about my personal and professional background as a teacher and a pedagogical supervisor in two public schools in the municipality of Natal, RN, and how relevant this background is to the development of a proposal of continued formation within the scope of the school, in which a diversity of actionreflection strategies are present. In such contexts, I have identified several of my personality traits as being likely advantages or disadvantages that may contribute or not to the coming up of misunderstanding situations. The self-research experience and the identification of new dimensions of self-evaluation, self-observation and attention serve as a basis to think about the importance of experiencing the understanding within the ambit of the school. The reflections about my actions and those of the teachers bring up the hypothesis that the misunderstandings in the teaching-learning process and in the affective relations are the result of a fragmented, naive and egotistic way of thinking. Thus, they don t contribute to an experience of mutual understanding. That is why there must be an investment on new strategies of self-research and dialogue within the scope of pedagogical meetings that may come to help all educators with the analysis, identification and solving of their own problems as well as the other s. Under this perspective, the question that guides this study assumes the presupposition that the educator can invest in a qualified and meaningful pedagogical formation, either one s own and others , if one has a critical-reflexive overview about oneself and the school s pedagogical process. This research aims to explore, discuss and encourage new reflections about the act of researching in the pedagogical supervisor s role, questioning about the possibility of this action to generate contributions to the process of one s own and other s pedagogical formation within the scope of the school, in a conscientiological perspective, in which the manifestation of the thosenes of the educators are valorized. We approach Paulo Freire (1921-1997), as we see the dialogue as very important to the development of this research work, as well as an encouragement to the consciential dialogue. The empirical research took place from June 4, 2004 to November 11, 2004, with 8 pedagogical meetings and with the participation of 2 pedagogical supervisors and 8 teachers. The application of this new methodology within the scope of pedagogical meetings brought considerable contributions to the interpretation of the elements of the educators thosenes, classified according to the following: uncritical, naïve and critical thoughts; sentiments of assistential or non-assistential affectivity; and actions that may or not make the experience of mutual understanding possible. The action of the pedagogical supervisor and one s contributions to the understanding brought up reflections about new ways of investing in the process of continued formation within the scope of the school

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

Desenvolvimento de um núcleo versátil e integrado de ferramentas CAD/CAE para a modelagem e simulação de peças mecânicas

Currently there is still a high demand for quality control in manufacturing processes of mechanical parts. This keeps alive the need for the inspection activity of final products ranging from dimensional analysis to chemical composition of products. Usually this task may be done through various nondestructive and destructive methods that ensure the integrity of the parts. The result generated by these modern inspection tools ends up not being able to geometrically define the real damage and, therefore, cannot be properly displayed on a computing environment screen. Virtual 3D visualization may help identify damage that would hardly be detected by any other methods. One may find some commercial softwares that seek to address the stages of a design and simulation of mechanical parts in order to predict possible damages trying to diminish potential undesirable events. However, the challenge of developing softwares capable of integrating the various design activities, product inspection, results of non-destructive testing as well as the simulation of damage still needs the attention of researchers. This was the motivation to conduct a methodological study for implementation of a versatile CAD/CAE computer kernel capable of helping programmers in developing softwares applied to the activities of design and simulation of mechanics parts under stress. In this research it is presented interesting results obtained from the use of the developed kernel showing that it was successfully applied to case studies of design including parts presenting specific geometries, namely: mechanical prostheses, heat exchangers and piping of oil and gas. Finally, the conclusions regarding the experience of merging CAD and CAE theories to develop the kernel, so as to result in a tool adaptable to various applications of the metalworking industry are presented

Não vício assintótico, consistência forte e uniformemente forte de estimadores do tipo núcleo para dados direcionais sobre uma esfera unitária k-dimensional

In this work we studied the asymptotic unbiasedness, the strong and the uniform strong consistencies of a class of kernel estimators fn as an estimator of the density function f taking values on a k-dimensional sphere

Estimadores do tipo núcleo para Variávei s I.I.D. com espaço de estados geral

In this work, the paper of Campos and Dorea [3] was detailed. In that article a Kernel Estimator was applied to a sequence of random variables with general state space, which were independent and identicaly distributed. In chapter 2, the estimator´s properties such as asymptotic unbiasedness, consistency in quadratic mean, strong consistency and asymptotic normality were verified. In chapter 3, using R software, numerical experiments were developed in order to give a visual idea of the estimate process

"O núcleo supraquiasmático e o folheto intergeniculado do mocó (Kerodon rupestris): Projeções retinianas e caracterização imuno-histoquímica

In this study, two circadian related centres, the suprachiasmatic nucleus (SCN) and the intergeniculate leaflet (IGL) were evaluated in respect to their cytoarchitecture, retinal afferents and chemical content of major cells and axon terminals with a tract tracer and immunohistochemical techniques in the rock cavy (Kerodon rupestris), a Brazilian caviidae rodent species. The rock cavy SCN is innervated in its ventral portion by terminals from the predominantly contralateral retina. It also contains neurophisin and vasoactive intestinal polypeptide immunoreactive cell bodies and neuropeptide Y and enkephalin immunopositive fibres and terminals and is marked by intense GFAP immunoreactivity. The IGL receives a predominantly contralateral retinal projection, contains neuropeptide Y and nitric oxide synthase producing neurons and enkephalin immunopositive terminals and is characterized by dense GFAP immunoreactivity. This is the first report examining the neural circadian system in a crepuscular rodent species for which circadian properties have been described. The results are discussed comparing with what has been described for other species and in the context of the functional significance of these centres

Expressão de fos após pulso de escuro no núcleo pré- geniculado do tálamo do sagui (Callithrix jacchus)

The pregeniculate nucleus (PGN) of the primate s thalamus is an agglomerate neuronal having a cap shaped located dorsomedially to the main relay visual information to the cerebral cortex, the dorsal lateral geniculate nucleus (GLD). Several cytoarchitectonic, neurochemical and retinal projections studies have pointed PGN as a structure homologous to intergeniculate leaflet (IGL) of rodents. The IGL receives retinal terminals and appears to be involved in the integration of photic and non-photic information relaying them, through geniculo-hypothalamic tract (TGH), to the main circadian oscillator in mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus. Thus, the IGL participates in the control of the biological rhythm by modulating the activity of the SCN. Pharmacological and IGL injury studies conclude that it is critical in the processing of non-photic information which is transmitted to the SCN. Other studies have found that especially neurons immunoreactive to neuropeptide Y (NPY) respond to this type of stimulation, determined by its colocation with the FOS protein. Has not been determined if the PGN responds, expressing the FOS protein, to the non-photic stimulus nor the neurochemical nature of these cells. Thus, we apply a dark pulse in the specifics circadian phases and analyze the pattern of expression of FOS protein in PGN of the marmoset (Callithrix jacchus). We found that in all animals analyzed the FOS expression was higher in the experimental than in the control group. There was a higher expression of FOS when the dark pulse was applied during the subjective day between the groups. Still, a subregion of the PGN, known by immunoreactive to NPY, had a greater number of FOS-positive cells in relation to his other just close dorsal region. Our data corroborate the theory that the PGN and IGL are homologous structures that were anatomically modified during the evolutionary process, but kept its main neurochemical and functional characteristics. However, injury and hodological studies are still needed for a more accurate conclusion

Efeitos da senescência no núcleo supraquiasmático do sagui (Callithrix Jacchus): plasticidade morfológica e neuroquímica

The circadian timing system (CTS) is responsible for the generation and synchronization and the suprachiasmatic nucleus (SCN) of the hypothalamus has been described as the major circadian pacemaker in many mammalian species. The internal temporal organization managed by SCN is disturbed with aging bringing many pathological disorders that range from loss of complex cognitive performance to simple physiological functions. Therefore, our aim was perform a comparative study of the morphological aspects and neurochemical composition in the SCN of marmosets (Callithrix jacchus) adults and older using immunohistochemical techniques. We found morphometric and neurochemical changes in th SCN o folder animals in comparison to adults, among these a possible decreased in retinal projection to the SCN of older animals, found through a decline in CTB immunostaining, which can occur due atrophy and/or decreasing of fibers from the retinohypothalamic tract (RHT). The Klüver-Barrera histological technique strongly suggests a decrease in those fibers from RHT. Also, by means of a morphometric study, it is found a atrophy and numerical decline of neurons in SCN of aged animals, investigated by Nissl technique, and immunostaining with NeuN and calbindin. Relative optical density (ROD) analysis were used to evaluate the expression of some neurochemical components in SCN, such as GFAP expression, which was increased in older, result that indirectly reinforces that morphological changes occurs due the aging; the vasoactive intestinal polipeptide (VIP) showed no expression alteration in SCN of older animals; the serotonin (5-HT) was descreased in the dorsomedial portion of the SCN, and neurpeptide Y (NPY) apparently also decrease due to the increase of age. Many of these modifications were seen in other animals, such as rodents, human primates and non-human primates. These data about marmoset comes to add new information of the effect of aging on structures responsibles for the circadian rhytmicity, and that some behavioral changes controlled by th SCN, and founded in aged animals, may be caused by these morphological and neurochemical changes. Although some results have been quantitatively negative, qualitatively all analysis show significant change comparing adult and older animals, perhaps due to a low sampling number. In conclusion, the marmoset presents several morphological and neurochemical changes in the SCN of aged animals compared to adults, which may result in behavioral changes that favor pathology aging related

Caracaterização do núcleo pré-geniculado do sagüi (Callithrix jacchus) :projeção retiniana, neuroquímica e atividade celular (expressão de FOS)

In rodents, the suprachiasmatic nucleus (SCN) and the intergeniculate leaflet (IGL) are the main components of the circadian system. The SCN is considerate the site of an endogenous biological clock because can to generate rhythm and to synchronize to the environmental cues (zeitgebers) and IGL has been related as one of the main areas that modulate the action of SCN. Both receive projections of ganglion cells of retina and this projection to SCN is called retinohypothalamic tract (RHT). Moreover, the IGL is connected with SCN through of geniculohypothalamic tract (GHT). In primates (include humans) was not still demonstrated the presence of a homologous structure to the IGL. It is believed that the pregeniculate nucleus (PGN) can be the answer, but nothing it was still proven. Trying to answer that question, the objective of our study is to do a comparative analysis among PGN and IGL through of techniques immunohystochemicals, neural tracers and FOS expression after dark pulses. For this, we used as experimental model a primate of the new world, the common marmoset (Callithrix jacchus). Ours results may contribute to the elucidation of this lacuna in the circadian system once that the IGL is responsible for the transmission of nonphotic information to SCN and participate in the integration between photic and nonphotic stimulus to adjust the function of the SCN. In this way to find a same structure in primates represent an important achieve in the understanding of the biological rhythms in those animals
