A SIR chegou... : Sala de Integração e Recursos e a inclusão na Rede Municipal de Ensino de Porto Alegre

A presente investigação tem como objetivo realizar um estudo a respeito da Sala de Integração e Recursos (SIR), analisando seu papel na garantia da permanência e educabilidade dos alunos com necessidades educativas especiais, nas escolas regulares da Rede Municipal de Ensino de Porto Alegre. Este espaço constitui-se como um serviço de apoio vinculado à educação especial existente no ensino comum, onde atuo como educadora especial. Dentro dessa abordagem, mereceu destaque a perspectiva educacional inclusiva e seus pontos de conexão com a proposta político-pedagógica da referida rede de ensino. A pesquisa tem uma abordagem qualitativa e o instrumento utilizado para a coleta dos dados foi a entrevista semi-estruturada. Os sujeitos entrevistados foram cinqüenta e quatro professores do município de Porto Alegre, divididos em dois grupos, formados pelos professores que atuam na Sala de Integração e Recursos e pelos professores de sala de aula do ensino comum. A perspectiva metodológica utilizada para analisar as entrevistas foi a Análise de Conteúdo. Foram analisadas as concepções dos entrevistados em torno de três grandes eixos: Que espaço é esse? Quem é atendido nesse espaço? A construção de parcerias. Nesses eixos destacam-se aspectos relativos ao conceito e caracterização desse espaço; o perfil dos alunos encaminhados; critérios utilizados para encaminhamento e conclusão do atendimento; aspectos facilitadores e problemáticos presentes no processo de construção do espaço de interlocução entre os professores envolvidos no trabalho da SIR Os resultados indicam que existe um processo de construção de parcerias entre os professores da SIR e aqueles do ensino comum, cujos alunos são atendidos nesse espaço. Apesar das evidências de que a Rede Municipal de Ensino de Porto Alegre tem oferecido apoios relativos à inclusão, a discussão a esse respeito ainda encontra-se muito centrada no educador especial e no espaço da SIR.

Construção de um índice de sustentabilidade ambiental para a agroindústria paulista da cana-de-açúcar (ISAAC)

Esta pesquisa apresenta uma proposta de construção de um índice de sustentabilidade ambiental para a agroindústria paulista da cana-de-açúcar – ISAAC. Tal proposta é motivada pela busca de sustentabilidade para a cadeia produtiva da cana, cujo energético principal, o etanol, é exigido, mundialmente, como biocombustível produzido em base socioeconômica responsável, proveniente de fonte renovável, ambientalmente limpa e redutora de emissões de Gases de Efeito Estufa – GEE. Este estudo faz um diagnóstico da produção de cana, açúcar e álcool, bem como da bioenergia gerada no Estado de São Paulo, em 16 Unidades de Gerenciamento de Recursos Hídricos – UGRHI[s], nas quais a agroindústria da cana-de-açúcar é significativa economicamente. O trabalho também aponta o ranking de produção das 164 usinas que operaram na safra 2007/2008, indica a ocupação do solo e a vegetação nativa nos 462 municípios canavieiros e inventaria, dentre outros, a geração de resíduos, as emissões de GEE, o uso da água, os postos de trabalho e o valor da produção. A pesquisa projeta ainda uma estimativa de custos para se mitigar, no horizonte de 30 anos, algumas externalidades negativas e realiza uma breve conceituação de responsabilidade socioambiental e desenvolvimento sustentável. Para o desenvolvimento do índice, empregou-se a metodologia Pressão-Estado-Resposta – PER, da Organização de Cooperação e Desenvolvimento Econômicos – OCDE, a partir da escolha de um conjunto de 30 indicadores, avalizados por meio de seis atributos de seleção e dez princípios norteadores. Na valoração ponderada dos subíndices, foram considerados o atual nível de conhecimento, a percepção acerca da sustentabilidade e as características próprias das UGRHI[s] estudadas. O conjunto dos indicadores e subíndices assim construído é apresentado à consulta das partes interessadas, via Câmara Ambiental Sucroalcooleira, da Companhia Ambiental do Estado de São Paulo – CETESB e Comitês de Bacias Hidrográficas – CBH, em razão da forma participativa de atuação destes colegiados. Vislumbra-se que a CETESB implemente institucionalmente o ISAAC, por meio de relatório de sustentabilidade, o qual poderá se consolidar como instrumento eficaz da gestão ambiental da agroindústria da cana-de-açúcar.

Murais modernos de Newton Navarro e Dorian Gray

This research aims to study wall paitings created by artists Newton Navarro and Dorian Gray, installed in public buildings of modern architecture, in Natal/RN from 1950 to 1970. The subject is seen by focusing on its concepts and characterization, linked to the ideia of integration of the arts and the meaning of modern mural painting in Brasil. The study presents an analyses of those paitings considering themes, techiniques and dimensions, comparing the solutions of local artists with brasilian muralist painters, particularly the work of Cândido Portinari. Registers of artistic works show a view of the inclusion of arts in modern architecture in the city

Problemas e modelos que contribuíram com o desenvolvimento do cálculo diferencial e integral: dos gregos à Newton

This article refers to a research which tries to historically (re)construct the conceptual development of the Integral and Differential calculus, taking into account its constructing model feature, since the Greeks to Newton. These models were created by the problems that have been proposed by the history and were being modified by the time the new problems were put and the mathematics known advanced. In this perspective, I also show how a number of nature philosophers and mathematicians got involved by this process. Starting with the speculations over scientific and philosophical natures done by the ancient Greeks, it culminates with Newton s work in the 17th century. Moreover, I present and analyze the problems proposed (open questions), models generated (questions answered) as well as the religious, political, economic and social conditions involved. This work is divided into 6 chapters plus the final considerations. Chapter 1 shows how the research came about, given my motivation and experience. I outline the ways I have gone trough to refine the main question and present the subject of and the objectives of the research, ending the chapter showing the theoretical bases by which the research was carried out, naming such bases as Investigation Theoretical Fields (ITF). Chapter 2 presents each one of the theoretical bases, which was introduced in the chapter 1 s end. In this discuss, I try to connect the ITF to the research. The Chapter 3 discusses the methodological choices done considering the theoretical fields considered. So, the Chapters 4, 5 and 6 present the main corpus of the research, i.e., they reconstruct the calculus history under a perspective of model building (questions answered) from the problems given (open questions), analyzing since the ancient Greeks contribution (Chapter 4), pos- Greek, especially, the Romans contribution, Hindus, Arabian, and the contribution on the Medium Age (Chapter 5). I relate the European reborn and the contribution of the philosophers and scientists until culminate with the Newton s work (Chapter 6). In the final considerations, it finally gives an account on my impressions about the development of the research as well as the results reached here. By the end, I plan out a propose of curse of Differential and Integral Calculus, having by basis the last three chapters of the article

Notes on Newton-Euler formulation of robotic manipulators

The equations corresponding to Newton-Euler iterative method for the determination of forces and moments acting on the rigid links of a robotic manipulator are given a new treatment using composed vectors for the representation of both kinematical and dynamical quantities. It is shown that Lagrange equations for the motion of a holonomic system are easily found from the composed vectors defined in this note. Application to a simple model of an industrial robot shows that the method developed in these notes is efficient in solving the dynamics of a robotic manipulator. An example is developed, where it is seen that with the application of appropriate control moments applied to each arm of the robot, starting from a given initial position, it is possible to reach equilibrium in a final pre-assigned position.

Os marcos da paisagem da cidade no contexto da trama urbana de Natal/RN: um estudo a partir do Morro do Careca, o Midway Mall, o Pórtico dos Reis Magos e a Ponte Newton Navarro

The present work is a study on the functions performed by landmarks landscape Natal / RN in the urban fabric, in the case of Midway Mall, the Portico dos Reis Magos, the Morro do Careca and Newton Navarro Bridge. For such goals established itself as analyze the functionality of the milestones presented here in the urban fabric; discuss the importance of these landmarks of the city landscape in the process of urbanization of Natal, and identify and spatialize actions related to the use of territories where are located landmarks, discussing their reflections. To achieve these goals we chose to use as a literature search procedures, the problematic concept, working with oral sources, and reading speechless. To support this research the main concepts were worked landscape, city, landmark, public space, circuits, among others. After going over the theory, consistent with the empirical data, it appears that the landmarks studied here have different functions and features, but all carry different forms of fascination for the public and visitors to the city, and every man your way, influence the public space, land speculation and feature importance in the process of urbanization of Natal

Ureteroscopy in Pregnant Women for Ureteral Stone

Introduction: The occurrence of urolithiasis in pregnancy represents a challenge in both diagnosis and treatment of this condition, because it presents risks not only to the mother but also to the fetus. Surgical treatment may be indicated for patients with infection, persistent pain, and obstruction of a solitary kidney. We present our experience on the management of pregnant patients with ureteral calculi and a review of the literature.Materials and Methods: The charts of 19 pregnant patients with obstructive ureteral calculi were retrospectively reviewed. Gestational age ranged from 13 to 33 weeks. In all patients, ureteral stone was diagnosed on abdominal ultrasound. In regard to localization, 15 calculi were in the distal ureter, 3 in the proximal ureter, and 1 in the interior of an ureterocele. Calculi size ranged from 6 to 10 mm (mean, 8 mm). The following criteria were used to indicate ureteroscopy: persistent pain with no improvement after clinical treatment, increase in renal dilation, or presence of uterine contractions. Nine patients (47.3%) were submitted to ureteroscopy. All calculi (100%) were removed with a stone basket extractor under continuous endoscopic vision. None of the calculi demanded the use of a lithotriptor.Results: Nine patients (47.3%) treated with clinical measurements presented no obstetric complications and spontaneous elimination of the calculi. Nine patients (47.3%) submitted to ureteroscopy had no surgical complications. There was remission of pain in all cases after ureteroscopy and ureteral catheter placement.Conclusion: The diagnosis and treatment of ureteral lithiasis in pregnant women present potential risks for the fetus and the mother. Conservative management is the first option, but ureteroscopy may be performed with safety and high success rates.

Bi-Lipschitz A-triviality of map germs and Newton filtrations

Bi-Lipschitz G-triviality and Newton polyhedra, G = R, C, K, R-V, C-V, K-V

In this work we provide estimates for the bi-Lipschitz G-triviality, G = C or K, for a family of map germs satisfying a Lojasiewicz condition. We work with two cases: the class of weighted homogeneous map germs and the class of non-degenerate map germs with respect to some Newton polyhedron. We also consider the bi-Lipschitz triviality for families of map germs defined on an analytic variety V. We give estimates for the bi-Lipschitz G(V)-triviality where G = R,C or K in the weighted homogeneous case. Here we assume that the map germ and the analytic variety are both weighted homogeneous with respect to the same weights. The method applied in this paper is based in the construction of controlled vector fields in the presence of a suitable Lojasiewicz condition. In the last section of this work we compare our results with other results related to this work showing tables with all estimates that we know, including ours.
