Análise morfométrica do colágeno dérmico a partir da segmentação por conglomerados (clusters) de cor
Resumo:
Análise morfométrica do colágeno dérmico pode fornecer subsídio quantitativo para a pesquisa em dermatologia. Os autores demonstram uma técnica de análise de imagem digital que permite a identificação de estruturas microscópicas, a partir da segmentação por conglomerados (clusters), de cor aplicada à estimativa da intensidade e densidade das fibras colágenas da derme.

O principal objetivo deste trabalho é verificar, por meio de uma pesquisa tipo survey, os benefícios e as dificuldades da adoção de Sistemas de Gestão Ambiental ISO 14001 em empresas industriais do Estado de São Paulo. Para tal, um questionário foi enviado para 194 empresas constantes da base de dados do INMETRO (Instituto Nacional de Metrologia, Normalização e Qualidade Industrial) e respondido por 69 delas, representando uma taxa de retorno de 35,36%. Duas hipóteses foram estabelecidas para realização do estudo: uma enunciando os potenciais benefícios e outra as dificuldades da gestão ambiental com base na norma NBR ISO 14001. Estas hipóteses foram parcialmente comprovadas. O artigo está estruturado da seguinte forma: introdução, sistema de gestão ambiental, norma NBR ISO 14001, método de pesquisa, apresentação e análise dos resultados, conclusão e referências bibliográficas.

Foram estabelecidos segmentos anatomocirúrgicos em pulmões de ovinos da raça Ideal (dezessete segmentos no pulmão direito e doze no esquerdo), mediante dissecação de peças coradas com látex colorido e fixadas em formol. Na maioria dos casos, a artéria pulmonar direita emite, a partir de um tronco, o ramo ascendente e descendente para as partes cranial e caudal do lobo cranial respectivamente; o ramo do lobo médio; o ramo do lobo caudal e o ramo do lobo acessório. Invariavelmente, a artéria pulmonar esquerda emite o ramo do lobo cranial e o ramo do lobo caudal.

In this paper is presented a region-based methodology for Digital Elevation Model segmentation obtained from laser scanning data. The methodology is based on two sequential techniques, i.e., a recursive splitting technique using the quad tree structure followed by a region merging technique using the Markov Random Field model. The recursive splitting technique starts splitting the Digital Elevation Model into homogeneous regions. However, due to slight height differences in the Digital Elevation Model, region fragmentation can be relatively high. In order to minimize the fragmentation, a region merging technique based on the Markov Random Field model is applied to the previously segmented data. The resulting regions are firstly structured by using the so-called Region Adjacency Graph. Each node of the Region Adjacency Graph represents a region of the Digital Elevation Model segmented and two nodes have connectivity between them if corresponding regions share a common boundary. Next it is assumed that the random variable related to each node, follows the Markov Random Field model. This hypothesis allows the derivation of the posteriori probability distribution function whose solution is obtained by the Maximum a Posteriori estimation. Regions presenting high probability of similarity are merged. Experiments carried out with laser scanning data showed that the methodology allows to separate the objects in the Digital Elevation Model with a low amount of fragmentation.

Background and objectives: Glass ampoules have been widely used in packaging injection drugs. Glass has important characteristics that allow it to be widely used in fabrication of recipients for drugs and other sterile substances. However, contamination of solutions with glass microparticles on breaking open glass ampoules, the presence of metals, percutaneous injury, and biological contamination justify the need of educational materials to orient the manipulation of ampoules. Contents: Glass microparticles generated in the snap-opening of ampoules, as well as metals that contaminate their contents can be aspirated and injected through several routes. Exogenous contaminations by glass and metals can reach several sites in the organism. They trigger organic reactions that may give rise to injuries. Opening ampoules can expose professionals to the risk of percutaneous injuries. These lesions increase the biological risk as they are the gateway for viruses and bacteria. Ampoules opening systems (VIBRAC and OPC) have been developed to reduce the incidence of such accidents. Alternative materials to glass may represent an interesting strategy to increase safety. The use of prefilled syringes may represent an evolution regarding safety. Conclusions: Team training and information provided by the pharmaceutical industry on the use of ampoules are fundamental in the prophylaxis of accidents and contaminations. The search for safer materials to replace glass is also important. © 2011 Elsevier Editora Ltda.

This work aims to identify the main motivations and difficulties faced by Brazilian companies to obtain ISO 9001 certification. The key quality management practices that provide support to this certification and the relationship with other types of systems, such as ISO 14001 (Environmental Management) and OHSAS 18001 (Occupational Health and Safety Management System), were also investigated. A survey research was conducted with 191 companies. The main motivations for implementing ISO 9001 are the following: internal organization improvement, production efficiency increase, and brand reliability improvement. Employee resistance was the greatest challenge found during the implementation process. On the other hand, the main benefits identified were: quality processes improvement and increased employee awareness of quality. The results reveal that the most common quality programs and tools used are: 5S, brainstorming, and Ishikawa diagram, while the least common are SERVQUAL and QFD.

In this paper, we analyzed situations where (a) one vocabular structure showed in two different ways in the same text or (b) had erasures. These structures fluctuations were extracted from texts written by children that, when the registers were done, were second graders of elementary school. Concerning the results, we verified: (1) that more than one prosodic constituent showed in the basis of fluctuation of vocabulary structures; and (2) that at least one of the limits of orthographic words was maintained in fluctuation structures. These results point to the recuperation done by writers with information they have access due to their insertion in (1) oral practices and (2) literacy practices.
