No. of bitstreams: 1 2016 - L?o Manso Ribeiro.pdf: 2045163 bytes, checksum: b33674eb288f4cea0f42bbb60c8a5a04 (MD5) Previous issue date: 2016-02-23 / We believe that the education management model presented by the government of Rio de Janeiro State transfers to teachers all responsibility for problems faced in education. The logic established by this new paradigm is based on a productivist vision and does not establish a proposal for public education guided by an emancipatory practice, that is, to enable students to understand their reality, showing only concern with the improvement of the indexes provided by the state network teaching the assessments established by the Ministry of Education (MEC). The choice for this research demonstrates our interest in contributing to the investigation into the current model of school management of the State Schools of Rio de Janeiro that determines restructuring the work of teachers. The relevance of this research directs to the expansion of knowledge about the reactions that teachers of Ciep Brizol?o 175 Jos? Rego Lins have in relation to the implementation of managerialism as a new paradigm of management of school work in the State Network of Rio State Education from January. For data collection, we use the following instruments: analysis of primary literature sources; analysis of secondary sources; application of a questionnaire with open questions and multiple choice (closed); interviews with key informants and field diary. We find that the social, political and economic management of this new paradigm of school work, conduct search students (workers) a conformation regarding the structure of contemporary society. And because of this, a significant number of teachers as well as the management team, have huge critical to the implementation of GIDE due to her focus the results to be achieved in IDEB instead of seeking to develop a management model that provides students the ability to become emancipated individuals. / Consideramos que o modelo de gerenciamento da educa??o apresentado pelo governo do Estado do Rio de Janeiro transfere aos professores toda a responsabilidade pelos problemas enfrentados na educa??o. A l?gica estabelecida por este novo paradigma ? fundamentada numa vis?o produtivista e n?o estabelece uma proposta de educa??o p?blica orientada por uma pr?tica emancipadora, ou seja, que permita aos estudantes compreender a sua realidade, demonstrando apenas preocupa??o com a melhora dos ?ndices apresentados pela rede estadual de ensino nas avalia??es estabelecidas pelo Minist?rio da Educa??o (MEC). A escolha por essa pesquisa demonstra nosso interesse em contribuir com as investiga??es sobre o atual modelo de gest?o escolar da Rede Estadual de Ensino do Rio de Janeiro que determina uma reestrutura??o no trabalho dos professores. A relev?ncia desta pesquisa direciona-se ? amplia??o do conhecimento a respeito das rea??es que os docentes do Ciep Brizol?o 175 Jos? Lins do Rego possuem em rela??o ? implanta??o do gerencialismo como novo paradigma da gest?o do trabalho escolar na Rede Estadual de Educa??o do Estado do Rio de Janeiro. Para levantamento de dados, nos utilizamos dos seguintes instrumentos: an?lise de fontes bibliogr?ficas prim?rias; an?lise de fontes secund?rias; aplica??o de um question?rio com quest?es abertas e de m?ltipla escolha (fechadas); entrevista com informante-chave e um di?rio de campo. Constatamos que o significado social, pol?tico e econ?mico deste novo paradigma de gest?o do trabalho escolar, busca conduzir os estudantes (trabalhadores) a uma conforma??o em rela??o a estrutura da sociedade contempor?nea. E, em fun??o disso, um n?mero expressivo de professores como tamb?m da equipe gestora, possuem enormes cr?ticas ? implanta??o da GIDE em decorr?ncia dela privilegiar os resultados a serem alcan?ados no IDEB ao inv?s de procurar desenvolver um modelo de gest?o que forne?a aos estudantes a capacidade de tornarem-se indiv?duos emancipados.

Paraleliza??o em GPU da segmenta??o vascular com extra??o de Centerlines por Height Ridges

One way to accomplish the segmentation is extracting the centerline of the vessel with height ridges, which uses the intensity as features for segmentation. This process can take from seconds to minutes, depending on the current technology employed. In order to accelerate the segmentation method proposed by Aylward [Aylward & Bullitt 2002] we have adapted it to run in parallel using CUDA architecture. The performance of the segmentation method running on GPU is compared to both the same method running on CPU and the original Aylward s method running also in CPU. The improvemente of the new method over the original one is twofold: the starting point for the segmentation process is not a single point in the blood vessel but a volume, thereby making it easier for the user to segment a region of interest, and; the overall gain method was 873 times faster running on GPU and 150 times more fast running on the CPU than the original CPU in Aylward / A segmenta??o vascular ? importante no diagn?stico de doen?as como o acidente vascular cerebral e ? dificultada por ru?dos na imagem e vasos muito finos que n?o s?o vistos. Uma maneira de realizar a segmenta??o ? extraindo a centerline do vaso com height ridges, que usa a intensidade como caracter?sticas para a segmenta??o. Este processo pode levar de segundos a minutos, dependendo da tecnologia atual empregada. O m?todo ? implementado em GPU, ou seja, ? executado de maneira paralela em placa gr?fica. O desempenho do m?todo de segmenta??o executado em GPU ? comparado com o mesmo m?todo em CPU e o m?todo original de Aylward em execu??o tamb?m na CPU. O melhoramento do novo m?todo sobre o original ? dupla. O ponto de partida para o processo de segmenta??o n?o ? um ?nico ponto no vaso sangu?neo, mas um volume, tornando assim mais f?cil para o usu?rio a sele??o de uma regi?o de interesse, e, o ganho do m?todo proposto foi 873 vezes mais r?pido sendo executado em GPU e 150 vezes mais r?pido sendo executado em CPU do que o original de Aylward em CPU
