Concess es de Rodovias do Paraná: Uma Análise Comparativa com o Modelo Federal de 2007 Highway concessions in Parana State: a comparative analysis against 2007 Federal model
Alessandro de Melo Perbelini,Maria da Piedade Araújo
Revista Paranaense de Desenvolvimento , 2008,
Abstract: Este trabalho tem por objetivo analisar, comparativamente, o Programa de Concess o de Rodovias do Estado do Paraná, implementado em 1997, em rela o ao modelo de Concess o de Explora o de Rodovia, realizado pelo governo federal, em 2007. Foram analisados os Lotes 3 e 2 dos contratos de concess o do Estado do Paraná e Federal, respectivamente. Buscou-se levantar as diferen as presentes nos dois modelos de concess o relacionadas aos contratos e seus anexos. Além disso, foi feita uma análise comparativa do histórico do valor médio da Tarifa Básica de Pedágio, referente à concess o do Estado do Paraná, utilizando-se a fórmula de reajuste proposta pela concess o federal. Os resultados mostram que, mediante os cálculos dos valores referentes aos reajustes tarifários, o usuário está pagando praticamente o mesmo valor da Tarifa Básica de Pedágio, caso o contrato estivesse sendo integralmente cumprido. Entretanto, uma gama considerável das obras referente ao trecho explorado foi reduzida ou encontra-se sub judice. Ainda, a fórmula de reajuste proposta pelo governo federal desencadearia um menor nível de tarifa para o usuário, caso fosse utilizada na concess o paranaense. This paper aims to perform a comparative analysis on the Highway Concession Program of the State of Parana, started in 1997, in relation to the model stipulated for the Roads Exploitation and Concession Program, accomplished by the Brazilian Federal Government, in 2007. It analyzed lots 3 and 2 of the concession contracts of Parana State and of the Federal Government, respectively. It tried to identify the differences in both these concession models, according to the contracts and their attachments. Besides, it was performed a comparative analysis of the historical average rates of the Basic Toll Fee in Parana State using the price adjustment formula proposed by the federal concession. The results obtained show that, under this method of costing fees, users would pay virtually the same value as the Basic Toll Fee, if the contracts had been fully observed. However, a considerable range of developments in the exploited road section were reduced or are currently sub judice. Yet, the price adjustment formula proposed by the federal government would provide lower fees for the user, if it was practiced in Parana concession.

Abstract: this paper contributes to the "work and education" area through the descriptive analysis and criticism of an important document produced by the cni (national confederation of industry) for the meeting of the ibero-american business presidents, held between july 12 and 16, 1993, in salvador (bahia, brazil). such analysis focuses on the questions raised about the relationship of brazilian entrepreneurs with the demands for basic education in order to form workers adapted to the needs of the work process characterized by the microelectronics revolution, and endowed with skills and expertise, which, from the early 90s on, have become the hegemonic banner of the brazilian educational field. in this sense, such document becomes more relevant because of its vanguardism, since it put forward trends that have been incorporated into the contemporary educational policies.
A educa??o básica na proposta da Confedera??o Nacional da Indústria (CNI) nos anos 2000

Educa??o e Pesquisa , 2012, DOI: 10.1590/S1517-97022011005000003
Abstract: this article has resulted from a doctoral thesis and it aims first to present and then to critically analyze the proposal of basic education of the national confederation of industry - cni, by describing and analyzing some documents of the confederation, publicly exposed over the 2000s. the basic education project of the brazilian business community attempts to meet need of this class to compete in the globalized and in crisis market, linking the increase in the level of education with the increase in productivity and innovation needed to achieve this project. the basis of this educational project is the return to the human capital theory, employability and entrepreneurship. in terms of social project, the businessmen refer to a social pact, that is, they intend to generalize a worldview to which applies not the conflict between capital and labor but the adaptation of workers to the class society. in such conception the emphasis is on an educational project that seeks accountability of individuals for their career. therefore, their inclusion or exclusion should be considered not a result of the macro-social structure, but a result of the individual effort to succeed, i.e., the worker's ability or lack of ability to be organically productive for the capital.
A redu??o ontológica do Homem à máquina em Marx: subsídios ao debate contemporaneo

Educa??o em Revista , 2009, DOI: 10.1590/S0102-46982009000200007
Abstract: this essay intends to be one more element of a debate about marx's contributions for the understanding and critic of the current society, which is characterized in economic terms by the progress of neoliberalism and the flexible accumulation of production.about this initial presupposition, the text intends to verify the book "the capital" the historical movement of workers' disqualification in the development of the productive forces in the capitalism: in its phases of cooperation, manufactures and machinery and big industry. these historicall elements are understood here by the concept of ontological reduction, that means the men, human work, as well as the whole society reduction only to economic determination. this reduction eliminates ideologically the elements of reality as a capital development condition. those elements are the capital origin and its support.

Abstract: objective: to analyze radiological findings observed at high-resolution computed tomography in patients with sarcoidosis, and establishing their correlation with pathological findings. materials and methods: high-resolution computed tomography findings in ten patients with sarcoidosis were reviewed and correlated with findings in specimens obtained by surgical biopsy or at necropsy of four of such patients. results: the most frequently observed finding was presence of nodules with perilymphatic distribution, predominating along bronchovascular sheaths and pleural surface, with subpleural nodules and nodular scissurae. other less frequent findings were ground-glass attenuation and interlobular septa thickening. conclusion: in general, all the mentioned findings demonstrated anatomopathological correlation with development of granulomas in these regions.

Abstract: traumatic mediastinal lesions are unusual findings in patients with thoracic trauma but may represent poor prognosis and be associated with severe lesions. mediastinal trauma is increasingly being diagnosed by computed tomography due to the fast acquisition times of helical techniques, allowing the evaluation of critically ill patients and the adoption of efficient therapeutic measures. the authors studied 11 patients with mediastinal lesions who were submitted to computed tomography due to thoracic trauma. the most frequent finding was mediastinal bleeding characterized by infiltration of mediastinal fat, dense material within the mediastinal spaces or hematoma. hemopericardium was the second most common lesion in this series, appearing as dense or liquid material in the pericardium. aortic lesions such as wall irregularities or pseudoaneurisms were less commonly seen (three patients). in this study blunt thoracic traumas were observed in six cases whereas penetrating trauma occurred in five cases. the causes of blunt trauma were pedestrians struck by car, motor vehicle accidents and falls. penetrating trauma was due to lesions produced by bullets or knifes.

Abstract: the authors report a case of a 40-year-old male patient with sickle cell disease who presented with intra-thoracic extramedullary hematopoiesis and paravertebral expansive lesions that appeared as soft tissue density masses on conventional x-ray films. a computed tomography of the chest demonstrated soft tissue density masses in the lower third of the paravertebral spaces. these masses presented well-defined limits, lobulated edges and were heterogeneous due to areas of interposed adipose and soft density tissues. the lung parenchyma had no abnormalities. computed tomography of the abdomen revealed diffuse hiperdensity and enlargement of the liver that was attributed to hemosiderosis, and an atrophic and calcified spleen due to repeated episodes of infarction.

Abstract: traumatic lesions of the lung are common findings in patients with thoracic trauma. these lesions are increasingly diagnosed using computed tomography, mostly due to the fast acquisition time helical techniques that allow evaluation of critically ill patients and an efficient therapeutic management. the authors studied 150 patients with thoracic trauma submitted to computed tomography that demonstrated lung contusions, atelectasies, lacerations and hematomas. lung contusions were the most frequent lesions appearing as consolidation or ground-glass attenuation areas. atelectasies, in subsegmentar and compressive patterns, were the second most common lesions observed. lacerations appeared as consolidations with air or liquid level. lung hematomas, characterized by round opacities, were the most rare lung lesions seen in only five cases. in this study, blunt thoracic trauma accounted for the majority of 120 cases whereas penetrating trauma occurred in 30 cases. the causes of blunt trauma in decrescent order of frequency were motor vehicle accidents, pedestrian hit by car, falls, motorcycle accidents and trashing. penetrating traumas were caused by bullets or knives.

Radiologia Brasileira , 2001,
Abstract: Os autores relatam o caso de um paciente do sexo masculino, de 40 anos de idade, portador de anemia falciforme, que desenvolveu a forma intratorácica de hematopoiese extramedular, apresentando les es expansivas com densidade de partes moles, localizadas posteriormente, nas goteiras paravertebrais, na radiologia convencional. A tomografia computadorizada do tórax demonstrou massas bem delimitadas, de contornos lobulados, com densidade heterogênea à custa de áreas de tecido gorduroso e de densidade de partes moles, localizadas no ter o inferior das goteiras paravertebrais. Os pulm es tinham coeficientes de atenua o preservados. A tomografia computadorizada de abdome revelou importante aumento da densidade e do volume do fígado, atribuídos à hemossiderose, e ba o atrófico e calcificado devido a infartos esplênicos de repeti o.

Radiologia Brasileira , 2001,
Abstract: O pseudomixoma peritoneal é um tumor incomum, de curso indolente, que se caracteriza pela presen a de ascite mucinosa ou implantes na cavidade peritoneal. Origina-se geralmente de les es no apêndice ou no ovário. O diagnóstico pode ser feito por meio da citologia de aspira o por agulha fina, ultra-sonografia, tomografia computadorizada ou ressonancia magnética. Os autores relatam três casos de pseudomixoma peritoneal cujo sítio primário era o ovário, e que foram submetidos a tomografia computadorizada e a ressonancia magnética do abdome. Este trabalho enfatiza a importancia destes métodos em fun o de sua capacidade de resolu o espacial, imagens multiplanares e diferentes seqüências (na ressonancia magnética), permitindo melhor avalia o das les es. Os exames tomográficos demonstraram massas lobuladas, hipodensas, com limites bem definidos, determinando "lobula es" nas margens hepática e esplênica por compress o extrínseca secundária a implantes peritoneais, sem invas o dos órg os. A ressonancia magnética revelou les es expansivas com baixo sinal nas imagens ponderadas em T1 e alto sinal em T2, de localiza o peritoneal, junto às margens do fígado e ba o.
