As Relações Da Família Com Os Pediatras: As Visões Maternais

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)To analyze the perception of pediatric guidelines by mothers at the time of consultation in private offices, in order to know how they assimilate, process and use the information received from the pediatricians. Methods Data collection was carried out by a questionnaire sent to participants by a total of 200 mothers from a virtual community in social networks participated in the research. The answers were transcribed using the Discourse of the Collective Subject method. The analyses were supported by the research qualitative perspective, from the viewpoint of the social representation theory. Results Three categories were obtained through data analysis: (1) assessing the pediatric guidelines, (2) confronting theory and practice and (3) developing a critical view of the pediatric guidelines. These categories have elucidated that the level of knowledge of pediatric issues by mothers and their ability to use them when making decisions about the care of their babies, have a direct association between following or not the pediatric guidelines. Conclusions The mother's decision on following the pediatrician's recommendations depends on two main factors: (a) certification of the updated and proven recommendations, according to the official health agencies; (b) support and recognition by the pediatrician of the maternal empowerment during the follow-up process. The mothers’ practice of accessing knowledge through social networks hinders the pediatric monitoring. © 2015 Sociedade de Pediatria de São Paulo343330335CAPES, Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Field redefinition invariant Lagrange multiplier formalism

In this paper, we propose a field redefinition invariant Lagrange multiplier (LM) formalism in which new ghost-like fields, analogous to Lee-Yang ghosts, are introduced. These ghost fields are required to restore the field redefinition invariance of the standard path integral of the LM theory and, at the same time, to cancel the additional contributions due to the LM fields. We argue that the extra degrees of freedom in the standard LM formalism, coming from the LM fields, should cancel against the degrees of freedom of the ghost fields. Hence, in the field redefinition invariant formalism the doubling of degrees of freedom, associated with the LM fields, is absent.Comment: 15 pages, 8 figures.

Optimal On-Off Attitude Control for the Brazilian Multimission Platform Satellite

This work deals with the analysis and design of a reaction thruster attitude control for the Brazilian Multimission platform satellite. The three-axis attitude control systems are activated in pulse mode. Consequently, a modulation of the torque command is compelling in order to avoid high nonlinear control action. This work considers the Pulse-Width Pulse-Frequency (PWPF) modulator which is composed of a Schmidt trigger, a first-order filter, and a feedback loop. PWPF modulator holds several advantages over classical bang-bang controllers such as close to linear operation, high accuracy, and reduced propellant consumption. The Linear Gaussian Quadratic (LQG) technique is used to synthesize the control law during stabilization mode and the modulator is used to modulate the continuous control signal to discrete one. Numerical simulations are used to analyze the performance of the attitude control. The LQG/PWPF approach achieves good stabilization-mode requirements as disturbances rejection and regulation performance

Multi-minicore Disease Revisited.

Multi-minicore disease (MmD) is an infrequent congenital myopathy, defined by structural changes in optic and electron microscopy, namely, multiple small areas lacking oxidative enzyme activity and focal disorganization of contractile proteins involving at most a few sarcomeres. The classical form of the disease manifests as more or less severe hypotonia and generalized weakness with predominance in axial and proximal limb muscles. Clinical variants also exist. Usually MmD is inherited as an autosomal recessive trait. Genetic heterogeneity is recognized and up to now mutations in the genes of RYR1 and SEPN1 have been detected. We record three unrelated cases of MmD. Case 1, with the classical benign form, was followed-up for 15 years. Case 2, presenting pharyngolaryngeal involvement and severe delay of head control, improved gradually, until independent gait was acquired at age of six years. A moderate restriction of daily life activities remains. Case 3, of antenatal-onset, was expressed by arthrogryposis of hands, predominance of scapular girdle deficit and a stable course after ten years on physiotherapy. All cases were selected by the characteristic morphological abnormalities in biceps brachii samples, including electron microscopy. Emphasis is given to case 2 due to type 1 fiber uniformity and mild endomysial fibrosis, posing a difficult differential diagnosis with congenital muscular dystrophy were it not for the significant number of multi-minicores.62935-
