ABSTRACT

Uno de los desafíos que los programadores tienen que enfrentar es la alta dimensión de grupos de datos. El proceso de reconocimiento de patrones en imagen y la minería de datos para los volúmenes grandes de información son ejemplos de ellos, optimizar la cantidad de veces que se recorre el conjunto de datos, disminuye el tiempo de procesamiento. Éste documento tiene el objetivo de caracterizar el algoritmo de tres pasos (S3), paralelo a K-medias, como una alternativa para afrontar la alta dimensión del conjunto de datos, en la clasificación no supervisada de imagen. Para el análisis de la concurrencia, se escoge, flujo de datos y el esquema instrucción única con datos múltiples. El resultado obtenido confirma que la concurrencia en ambos es posible, S3 no depende de la selección inicial de los representantes y puede ser el proceso de escogimiento de los primeros vectores centrales en K-medias. S3 es una alternativa a ser tenida en cuenta en la clasificación no supervisada de imágenes médicas y procesos de minería de datos(AU)


One of the challenges to be faced by programmers is the large dimensions of data groups. The process of pattern recognition in images and data mining for great volumes of information is an example. Optimizing the number of times that the set of data is run saves processing time. The purpose of the study was to characterize the three-step (S3) algorithm, parallel to k-means, as an alternative to cope with the large dimension of the data set in unsupervised image classification. Concurrence analysis is based on data flow and the single instruction multiple data scheme. The result obtained confirms that concurrence of both is possible. S3 does not depend on initial selection of representatives, and may be the process for selection of the first central vectors in k-means. S3 is an alternative to be considered in the unsupervised classification of medical images and data mining(AU)

ABSTRACT

Este artigo trata da participação de representantes de trabalhadores em comissões intersetoriais de saúde do trabalhador (CIST) e também de estratégias destes profissionais na defesa do seu direito à saúde. Para tanto, realizamos revisão bibliográfica sobre ideias centrais nesse campo, leitura dos relatórios de conferências e entrevistas com representantes dos trabalhadores que participam da coordenação dessas comissões no âmbito estadual, especialmente em São Paulo, e na CIST Nacional. O trabalho aponta para a tensão presente na relação entre cidadania e mercado na construção social da efetivação do direito à saúde do trabalhador. Em relação ao controle social, as conferências nacionais da área e a resolução do Conselho Nacional de Saúde que estimula os conselhos a criarem as CIST possibilitam a consolidação da Política Nacional de Saúde do Trabalhador e da Trabalhadora. Contudo, a pesquisa mostra a necessidade de ações institucionais conjuntas para o fortalecimento da participação na construção da agenda, formulação, implementação e avaliação de políticas públicas de saúde do trabalhador.


This paper deals with the participation of worker representatives in workers' health inter-sector commissions (in Portuguese, CIST). Moreover, it approaches these professionals' strategies to defend the workers' right to health. In order to achieve these goals, we reviewed the literature to find the main ideas in this field, read conference reports and interviewed worker representatives who participate in the coordination of these commissions at the state level, especially in São Paulo, and in the national CIST. The study reveals the tension that is present in the relationship between citizenship and the market in the social construction of the accomplishment of workers' right to health. In relation to social control, the national conferences in the area and the National Health Council's resolution that stimulates councils to create CISTs enable the consolidation of the National Workers' Health Policy. However, the research shows the necessity of joint institutional actions in order to strengthen participation in the construction of the agenda, formulation, implementation and evaluation of worker's health public policies.
