O desenvolvimento do sistema capitalista, à medida que aumenta a eficiência da produção contribui para uma cada vez maior concentração da riqueza e, em conjunto com as reformas neoliberais ocorridas durante o final do século XX, para uma mudança significativa na produção, bem como nos níveis de emprego formal, especialmente no Brasil. Buscando amenizar esses problemas, surgiram inúmeras iniciativas associativistas, que se cristalizaram na forma da Economia Solidária no Brasil nos anos 80. Para compreender e coordenar esse novo movimento inúmeras instituições foram criadas e cada vez mais atores se apresentaram para constituir a atual configuração dos empreendimentos solidários, estes baseados na cooperação, auto-gestão e solidariedade. Como resultado de toda essa organização os empreendimentos solidários aumentaram em número e importância econômica durante os últimos 30 anos. Neste trabalho analiso essa trajetória bem como tomo o exemplo da Cooperativa de limpeza do Jardim Gonzaga para demonstrar se a Economia Solidária é de fato um movimento de alternativa ao desemprego para as populações excluídas, sendo abandonada assim que as taxas de emprego formais melhorem, ou não, sendo uma nova forma duradoura de conceber a produção

In today's competitive environment of automakers, it is essential to obtain the highest efficiency of the production process. This paper presents a study in a pre-assembly of brake pipes and fuel of a vehicle where the value stream maps and information (VSM – Value Stream Mapping) were designed in order to improve the process by reducing the Lead Time Production of a product, reducing waste and decrease time between processes. This work can be divided into three stages, the first building the VSM of the initial state, the second VSM of the proposed state and finally the VSM than was actually performed and to present the gains were achieved effectively. The proposed VSM would lead to a gain of 54% in lead time and 61% in processing time, since the VSM implemented had gains of 47% in lead time and 48% in processing time even without major investments as originally proposed. Concluding that even without big investment, using the techniques of lean manufacturing is possible to achieve high levels of process efficiency

Este trabalho discute sobre como a habitação social vem sendo desenvolvida no Brasil e apresenta uma proposta de loteamento urbano para as classes sociais menos favorecidas economicamente na cidade de Presidente Prudente. A idéia do projeto é a de comparar um loteamento com vias ortogonais, lotes privados e espaços de lazer públicos bem separados, com uma proposta cujas unidades habitacionais estariam dispostas de forma a criar áreas verdes integradas ao convívio social. Para isso foram considerados aspectos sociais, econômicos, formais e funcionais. A elaboração do trabalho começou com estudos sobre o tema e com levantamento bibliográfico, quando nasce essa inquietação sobre habitação social no Brasil, verificou-se a carência de bons projetos arquitetônicos em uma relação quantitativa. A partir daí, foram analisadas diversas pesquisas e propostas que relacionam a urbanização brasileira e a forma como ela se apresenta com relação a unidades habitacionais, com interesse social, ou seja, para pessoas de baixa renda, com foco na cidade de Presidente Prudente (São Paulo). De acordo com esses estudos, foi feito um levantamento de possíveis áreas de implantação de um loteamento onde foi constatada a existência de um terreno não edificado, em uma área com infra-estrutura e dentro do perímetro urbano. Esta área de aproximadamente 100 mil metros quadrados foi escolhida para a realização do trabalho de comparação das diferentes formas de produção do espaço urbano

This monograph aims contribute to point out the presence of technical procedures, formal and thematic elements, typical of the Symbolist/Decadentism aesthetic in lyric poetry of Al Berto (1948-1997), using the Camilo Pessanha’s (1867-1926) work as tool to comparison. To achieve this goal, we analyze the corpus selected for research, consisting of three Pessanha’s poems taken from the book that brings together his work, Clepsidra, “Caminho I”, “Caminho II” e “[Depois das bodas de oiro]”, and three poems of Al Berto, taken from the book O Medo, which is the combination of his work too: “Os dias sem ninguém - 4”, “Doze moradas de silêncio – I” and “[no exíguo espaço do corpo ou da casa]”. Through the comparison between the analysis of the poems from Al Berto and Camilo Pessanha it was found resemblances, in fact, - and obviously some differences - between both. Furthermore, it was verified that Al Berto, a contemporary poet, rescues numerous traits of the decadent aesthetic, whose Camilo Pessanha is one of the greatest representatives

In the recent years, the use of proton beams in radiotherapy has been an outstanding progress (SMITH, 2006). Up to now, computed tomography (CT) is a prerequisite for treatment planning in this kind of therapy because it provides the electron density distribution required for calculation of dose and the interval of doses. However, the use of CT images for proton treatment planning ignores fundamental differences in physical interaction processes between photons and protons and is, therefore, potentially inaccurate (SADROZINSKI, 2004). Proton CT (pCT) can in principle directly measure the density distribution needed in a patient for the dose distribution (SCHULTE, et al, 2004). One important problem that should be solved is the implementation of image reconstruction algorithms. In this sense, it is necessary to know how the presence of materials with different density and composition interfere in the energy deposition by ionization and coulomb excitation, during its trajectory. The study was conducted in two stages, was used in both the program SRIM (The Stopping and Range of Ions in Matter) to perform simulations of the interaction of proton beams with pencil beam type. In the first step we used the energies in the range of 100-250 MeV (ZIEGLER, 1999). The targets were set to 50 mm in length for the beam of 100 MeV, due to its interaction with the target, and short-range, and 70 mm for 150, 200 and 250 MeV The target was composed of liquid water and a layer of 6 mm cortical bone (ICRP). It were made 9 simulations varying the position of the heterogeneity of 5 mm. In the second step the energy of 250 MeV was taken out from the simulations, due to its greater energy and less interaction. The targets were diminished to 50 mm thick to standardize the simulations. The layer of bone was divided into two equal parts and both were put in the ends of the target... (Complete abstract click electronic access below)

Dentro da perspectiva delineada por Jürgen Habermas, que delineia um conceito normativo de esfera pública e de sua importância na democracia, esta pesquisa se propõe a analisar como o jornalismo pode contribuir para a construção da opinião pública, que pressiona os poderes formais. Diante das mudanças nos modos de participação da sociedade civil no poder político, as informações e opiniões relacionadas aos movimentos sociais na imprensa são de extrema importância para a reflexão sobre a democracia. Com o objetivo de entender as contribuições do jornalismo sobre as questões levadas ao público pelos movimentos sociais, este trabalho propõe uma análise do jornal Le Monde Diplomatique Brasil. A partir do método de Análise de Conteúdo proposto por Laurence Bardin, que prioriza a análise qualitativa, a pesquisa busca compreender a constituição e as ideias presentes nos textos e sua relevância para os debates na esfera pública. Desse modo, busca-se apontar pontos positivos e negativos na cobertura jornalística do veículo, que possam contribuir tanto para a prática quanto para os estudos do jornalismo

The market has forced companies to maintain high levels of control over their processes , ensuring a product or service quality to its customers . This study comes in the issuance and registration carried out in a company of e-commerce , which is showing problems with the values of weights and dimensions used in the cases cited . The need to eliminate wasteful spending freight caused by shipment of products weighing more than the reality, and to increase the reliability of the information used in the management of processes led to the planning of this project . This work focuses on the development of a PDCA cycle to work in the identification and correction of the causes of the problem , in order to neutralize the current complications and ensure that the problem does not appear again. To aid the mapping of the processes involved , identifying the causes of the problem and implementation of the proposed improvements were used quality tools such as flowcharts , Ishikawa diagrams , Pareto diagrams , and applied statistics

The aim of this work is to study some of the density estimation tec- niques and to apply to the segmentation of medical images. Medical images are used to help the diagnostic of tumor diseases as well as to plan and deliver treatment. A computer image is an array of values representing colors in some scale. The smallest element of the image to which it is possible to assign a value is called pixel. Segmen- tation is the process of dividing the image in portions through the classi¯cation of each pixel. The simplest way of classi¯cation is by thresholding, given the number of portions and the threshold values. Another method is constructing a histogram of the pixel values and assign a portion to each pike. The threshold is the mean between two pikes. As the histogram does not form a smooth curve it is di±cult to discern between true pikes and random variation. Density estimation methods allow the estimation of a smooth curve. Image data can be considered as mixture of different densities. In this project parametric and nonparametric methods for density estimation will be addressed and some of them are applied to CT image data

This paper deals with so called cleft constructions and other similar structures in eight Portuguese varieties, aiming to show that the formal differences correspond to different functional strategies used by the Speaker to achieve his/her communicative intentions, i.e., Focus, Contrast and Emphasis, in accordance with the theory of Functional Discourse Grammar (Hengeveld and Mackenzie, 2008). This study takes as evidence real spoken occurrences extracted from a corpus organized by Linguistic Centre at the University of Lisbon, in partnership with the University of Toulousse Mirail and the University of Provence-Aix-Marseille. The results show the following distribution: cleft construction is a strategy for pragmatic function Contrast marking; Focus-ser constructions are used to highlight a constituent and (é) que is used as an operator of emphasis showing the speaker’s desire to intensify certain pieces of information.

This work deals with the distinction between embedded questions and headless relatives, that was already pointed out as problematic in several studies based on generative approach. The purpose is to examine to what extent functional aspects, as proposed by the theory of Functional Discourse Grammar (HENGEVELD; MACKENZIE, 2008) to describe the two types of clauses can contribute to the explanation of the differences and similarities between them. Based on representative occurrences of spoken Brazilian Portuguese, we demonstrated that the approach of Functional Discourse Grammar provides important parameters for defining the nature of these two types of clauses, in both formal and functional (semantic-discursive) terms, contributing thus to the existing proposals for the distinction between these clauses.

Este trabalho concentra-se na tradução de poemas infantis em língua inglesa, examinando, em particular, as denominadas nursery rhymes, componentes do cancioneiro popular na cultura do Reino Unido. Serão considerados aspectos formais e históricos dessa categoria poética e apresentadas sugestões de tradução para alguns poemas, com base nos conceitos de correspondência formal e correspondência funcional, elaborados por Paulo Henriques Britto, como aplicados ao processo tradutório (ademais de seu emprego na crítica de tradução poé- tica). Foram selecionados para tradução e exemplificação das discussões três poemas de temáticas diversas, extraídos das coletâneas organizadas por Peter e Iona Opie, The Oxford Dictionary of Nursery Rhymes (1952/1997) e A Family Book of Nursery Rhymes (1964).
