Assistência ao parto no Município do Rio de Janeiro: perfil das maternidades e o acesso da clientela
Campos, Tatiana Pacheco;Carvalho, Marilia Sá;
Cadernos de Saúde Pública , 2000, DOI: 10.1590/S0102-311X2000000200011
Abstract: the purpose of this paper is to identify and describe rio de janeiro maternity hospital profiles and the route between the mother's place of residence and the hospital. data sources were: the state live birth information system (1995) and the national survey on medical care (1992). two groups of maternity hospitals were identified using multivariate cluster analysis. group a had an extremely high cesarean rate (81%), with mothers and neonates presenting good health conditions. cesarean rates were lower in group b, although still high (32%), and other variables reflected worse neonatal conditions. cesarean rate was the indicator which best discriminated between the groups, followed by proportion of adolescent mothers and mothers with a high school education. the uneven spatial distribution of maternity hospitals, which were concentrated in the richest area of the city, was a factor in the long routes used by women to reach medical care for childbirth.
Assistência ao parto no Município do Rio de Janeiro: perfil das maternidades e o acesso da clientela
Campos Tatiana Pacheco,Carvalho Marilia Sá
Cadernos de Saúde Pública , 2000,
Abstract: Neste trabalho analisou-se a assistência ao parto, caracterizando o perfil das principais maternidades e o deslocamento da clientela, ou seja, o fluxo entre residência e local de nascimento. Os indicadores utilizados foram construídos a partir do Sistema de Informa o sobre Nascidos Vivos (SINASC) em 1995 e da Pesquisa sobre Assistência Médico-Sanitária (AMS), com dados para 1992. Através de classifica o multivariada foram identificados dois tipos de maternidades: um com grande número de partos cesáreos, boas condi es da parturiente e recém-nato; e outro com maior propor o de partos espontaneos e indicadores que apontam riscos do recém-nascido. As propor es de: m es com escolaridade igual ou superior ao ensino médio, m es adolescentes e partos cesáreos s o os indicadores que melhor caracterizaram os grupos. Identificou-se grande heterogeneidade na distribui o espacial das maternidades, concentrados nas regi es mais ricas da cidade, determinando, conseqüentemente, longos trajetos das gestantes na busca da assistência ao parto.

Abstract: the events included in the process of repair of corneal damage occur simultaneously and involve proliferation, migration, differentiation, cell apoptosis and intercellular communication. several soluble factors, mesenchymal matrix proteins, proteoglycans, proteolytic enzymes and some cell types are covered in this review, which explains the processes of repair of corneal wounds, either superficial or penetrating. the amniotic membrane, used in ophthalmic surgery, was studied because of the contribution of its functions to the repair process. however, these functions may be lost when the amniotic membrane is subjected to conservation. therefore, it is important to understand the repair process of lesions involving or not the entire thickness of the cornea, and choose the best use of the amniotic membrane, when it is indicated for the treatment of these lesions.
Bonding evolution with sintering temperature in low alloyed steels with chromium
Fuentes-Pacheco L.,Campos M.
Science of Sintering , 2009, DOI: 10.2298/sos0902161f
Abstract: At present, high performance PM steels for automotive applications follow a processing route that comprises die compaction of water-atomized powder, followed by sintering and secondary treatments, and finishing operations. This study examines Cr-alloyed sintered steels with two level of alloying. In chromium-alloyed steels, the surface oxide on the powder is of critical importance for developing the bonding between the particles during sintering. Reduction of this oxide depends mainly on three factors: temperature, dew point of the atmosphere, and carbothermic reduction provided by the added graphite. The transformation of the initial surface oxide evolves sequence as temperature increases during sintering, depending on the oxide composition. Carbothermic reduction is supposed to be the controlling mechanism, even when sintering in hydrogen-containing atmospheres. The effect of carbothermic reduction can be monitored by investigating the behavior of the specimens under tensile testing, and studying the resultant fracture surfaces.
Estudio de la estabilidad térmica de polvo de hierro nanoestructurado en función del tipo de refuerzo (Nb, NbC) y de su contenido
Fuentes-Pacheco, L.,Campos, M.,Torralba, J. M.
Revista de Metalurgia , 2011,
Abstract: In structural steels, an effective strategy to succeed in increasing both strength and toughness is the grain refining, like in microalloyed steels. To delay or even inhibit the grain growth there are two basic mechanisms: particle pinning and solute drag. The effect of the presence of small particles of NbC to inhibit the austenitic grain growth is well known. However, it is not so clear which mechanism will be more effective to delay ferritic grain growth. In order to confirm it, nanostructured iron powders reinforced with Nb and NbC have been prepared by mechanical alloying. The main objective of this work is, therefore, to study the thermal stability of the nanostructured powder as a function of the reinforce type (elemental Nb or NbC) and its content. En los aceros estructurales, una estrategia efectiva para incrementar tanto la resistencia como la tenacidad es disminuir el tama o de grano, tal y como ponen de manifiesto los aceros microaleados. Para retrasar e incluso inhibir el crecimiento de grano existen dos mecanismos básicos: la presencia de partículas de una segunda fase (“particle pinning”) y la presencia de elementos en solución sólida substitucional (“solute drag”). El efecto de la presencia de NbC para inhibir el crecimiento del grano asutenítico está más que demostrado. Sin embargo, no está claro cuál de los dos mecanismos (particle pinning o solute drag) es el más efectivo para retener el grano ferrítico. Para comprobarlo se han preparado polvos de hierro nanoestructurado mediante aleación mecánica, reforzados bien con niobio, bien con NbC. El presente trabajo tiene como objetivo estudiar la estabilidad térmica de la ferrita de dichos polvos en función del tipo de refuerzo (Nb en forma elemental o NbC) y de su contenido.

Abstract: this paper aimed to show the integration between environmental psychology, developmental psychology, and early childhood education, focusing on two groups of empirical studies on spatial organization in day-care centers: (1) studies on spatial arrangement (the way in which furniture / equipments are arranged in rooms for 1-2/2-3/3-4 year-old children); (2) studies on a north-american scale for assessing the quality of center-based child care, and another study on principles of quality of day-care centers in national and foreign documents. the first group has shown that spatial arrangement is one of the environmental elements which mediate interaction between child-child and child-educator, favoring certain educational and interactive practices and avoiding others. the second group has indicated that the scale is suitable for the brazilian context and quality indicators can be shared. such empirical data demonstrate the possibility of integrating environmental psychology, developmental psychology and early childhood education.

Abstract: nursing education history in brazil was re-visited, beginning with the foundation of the anna nery school of nursing in 1922, followed by the analysis of the teaching programs of 1923, 1926 and 1949, and of the national curriculum for nursing education of 1962, 1972 and 1994. in spite of the fact that modern nursing in brazil was established to qualify nurses to work in public health, since the beginning they were trained in hospitals, with the systematic study of diseases, without giving priority to subjects linked to public health. although the reformulation that resulted in the 1994 curriculum was committed to the construction of an education proposal that was non-hegemonic in nursing, the subdivision in medical specialties was preserved, as a result of the adoption of the flexnerian model. the biomedical, individualized and hospital-based model that influenced nursing education from it origins in brazil is still present and nursing education is not focused on the population needs, being therefore antagonistic to the presuppositions of collective health.
