Utilização do brinquedo terapêutico na assistência à criança hospitalizada

Estudo exploratório e descritivo, parte integrante de um projeto de parceria entre o Serviço de Enfermagem e de Terapia Ocupacional no preparo da criança para as cirurgias eletivas no Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo. OBJETIVO: utilizar o brinquedo como recurso terapêutico no alívio das tensões reais e inconscientes da criança em relação à hospitalização. MÉTODO: Foi construído um instrumento de coleta dos dados em forma de roteiro observacional, e aplicado em dois momentos: o primeiro consiste no dia anterior à realização da cirurgia e o segundo momento no dia da cirurgia imediatamente antes de sua realização. Utilizamos a contação de história e a demonstração das intervenções de enfermagem nos brinquedos (bonecos) com equipamentos e materiais comumente utilizados na hospitalização (luvas, aventais cirúrgico, máscara facial e gorro cirúrgico). RESULTADOS: Dentre as 21 variáveis de comportamento observadas, oito obtiveram diferença estatisticamente significativa com teste de McNemar (p>0,05). CONCLUSÃO: brincar interativamente proporciona à criança hospitalizada interagir com o ambiente hospitalar, expressar os seus sentimentos e emoções e provê recursos para a assistência humanizada.

O artigo explora a possibilidade de integração no processo de aprendizagem à rede de serviços de saúde do subsistema de saúde indígena integrante do Sistema Único de Saúde e colabora com o processo de formação profissional na área da saúde. Enfatiza também que a concepção pedagógica e as metodologias de ensino-aprendizagem são temas importantes para o desenvolvimento das competências dos novos profissionais da saúde. Com isto, o objetivo deste artigo é apresentar, através da análise descritiva, o contexto em que se desenvolve o processo preparatório para o estágio optativo "Projeto Huka-Katu - a FORP-USP no Xingu", ressaltando os aspectos cognitivos presentes na proposição de ações voltadas para a atenção primária. Considera-se ainda que as competências requeridas para o trabalho do cirurgião-dentista na atenção básica à saúde se constituem em um suporte (base) para a construção do SUS, sendo que estas competências devem atender as necessidades de articulação da prática e da educação, em uma perspectiva do cuidado à saúde.

Hidróxidos duplos lamelares: nanopartículas inorgânicas para armazenamento e liberação de espécies de interesse biológico e terapêutico

Studies about the inorganic nanoparticles applying for non-viral release of biological and therapeutic species have been intensified nowadays. This work reviews the preparation strategies and application of layered double hydroxides (LDH) as carriers for storing, carrying and control delivery of intercalated species as drugs and DNA for gene therapy. LDH show low toxicity, biocompatibility, high anion exchange capacity, surface sites for functionalization, and a suitable equilibrium between chemical stability and biodegradability. LDH can increase the intercalated species stability and promote its sub-cellular uptake for biomedical purposes. Concerning the healthy field, LDH have been evaluated for clinical diagnosis as a biosensor component.

Este ensaio aborda o histórico do Projeto SABE, nas versões de pesquisa do ano 2000 e 2006

Fatores relacionados à autopercepção da audição entre idosos do município de São Paulo - Projeto SABE

Este artigo relata a influência de fatores sociodemográficos e de saúde na autopercepção da audição entre os idosos do projeto " Saúde, Bem-Estar e Envelhecimento" (Projeto SABE) no município de São Paulo. O estudo incluiu 2.143 indivíduos de 60 anos e mais. Um modelo de regressão logística ordinal, considerando o desenho da amostra, foi usado na análise multivariável. O aumento da idade; o sexo masculino; morar acompanhado; relatar tontura; memória regular/ ruim e saúde regular ou ruim aumentaram a chance de autopercepção ruim da audição. O conhecimento da autopercepção da audição e dos seus fatores relacionados é importante para avaliar a qualidade de vida dos idosos e a necessidade de reabilitação auditiva

Modelo de programação linear para otimização econômica do projeto de irrigação Baixo Acaraú - CE

The present work had as objective uses a model of lineal programming algorithm to optimize the use of the water in the District of Irrigation Baixo Acarau-CE proposing the best combination of crop types and areas established of 8,0 ha. The model aim maximize the net benefit of small farmer, incorporating the constraints in water and land availability, and constraints on the market. Considering crop types and the constraints, the study lead to the following conclusions: 1. The water availability in the District was not a limiting resources, while all available land was assigned in six of the seven cultivation plans analyzed. Furthermore, water availability was a restrictive factor as compared with land only when its availability was made to reduce to 60% of its actual value; 2. The combination of soursop and melon plants was the one that presented the largest net benefit, corresponding to R$ 5,250.00/ha/yr. The planting area for each crop made up to 50% of the area of the plot; 3. The plan that suggests the substitution of the cultivation of the soursop, since a decrease in annual net revenue of 5.87%. However, the plan that contemplates the simultaneous substitution of both soursop and melon produced the lowest liquid revenue, with reduction of 33.8%.

Equifocality of a singular Riemannian foliation

A singular foliation on a complete Riemannian manifold M is said to be Riemannian if each geodesic that is perpendicular to a leaf at one point remains perpendicular to every leaf it meets. We prove that the regular leaves are equifocal, i.e., the end point map of a normal foliated vector field has constant rank. This implies that we can reconstruct the singular foliation by taking all parallel submanifolds of a regular leaf with trivial holonomy. In addition, the end point map of a normal foliated vector field on a leaf with trivial holonomy is a covering map. These results generalize previous results of the authors on singular Riemannian foliations with sections.

Singular Perturbation for the Discounted Continuous Control of Piecewise Deterministic Markov Processes

This paper deals with the expected discounted continuous control of piecewise deterministic Markov processes (PDMP`s) using a singular perturbation approach for dealing with rapidly oscillating parameters. The state space of the PDMP is written as the product of a finite set and a subset of the Euclidean space a""e (n) . The discrete part of the state, called the regime, characterizes the mode of operation of the physical system under consideration, and is supposed to have a fast (associated to a small parameter epsilon > 0) and a slow behavior. By using a similar approach as developed in Yin and Zhang (Continuous-Time Markov Chains and Applications: A Singular Perturbation Approach, Applications of Mathematics, vol. 37, Springer, New York, 1998, Chaps. 1 and 3) the idea in this paper is to reduce the number of regimes by considering an averaged model in which the regimes within the same class are aggregated through the quasi-stationary distribution so that the different states in this class are replaced by a single one. The main goal is to show that the value function of the control problem for the system driven by the perturbed Markov chain converges to the value function of this limit control problem as epsilon goes to zero. This convergence is obtained by, roughly speaking, showing that the infimum and supremum limits of the value functions satisfy two optimality inequalities as epsilon goes to zero. This enables us to show the result by invoking a uniqueness argument, without needing any kind of Lipschitz continuity condition.

A collocation method for solving singular integro-differential equations

This paper describes a collocation method for numerically solving Cauchy-type linear singular integro-differential equations. The numerical method is based on the transformation of the integro-differential equation into an integral equation, and then applying a collocation method to solve the latter. The collocation points are chosen as the Chebyshev nodes. Uniform convergence of the resulting method is then discussed. Numerical examples are presented and solved by the numerical techniques.

A singular integro-differential equation model for dryout in LMFBR boiler tubes

A 2D steady model for the annular two-phase flow of water and steam in the steam-generating boiler pipes of a liquid metal fast breeder reactor is proposed The model is based on thin-layer lubrication theory and thin aerofoil theory. The exchange of mass between the vapour core and the liquid film due to evaporation of the liquid film is accounted for using some simple thermodynamics models, and the resultant change of phase is modelled by proposing a suitable Stefan problem Appropriate boundary conditions for the now are discussed The resulting non-lineal singular integro-differential equation for the shape of the liquid film free surface is solved both asymptotically and numerically (using some regularization techniques) Predictions for the length to the dryout point from the entry of the annular regime are made The influence of both the traction tau provided by the fast-flowing vapour core on the liquid layer and the mass transfer parameter eta on the dryout length is investigated

Beyond the average: Detecting global singular nodes from local features in complex networks

Deviations from the average can provide valuable insights about the organization of natural systems. The present article extends this important principle to the systematic identification and analysis of singular motifs in complex networks. Six measurements quantifying different and complementary features of the connectivity around each node of a network were calculated, and multivariate statistical methods applied to identify singular nodes. The potential of the presented concepts and methodology was illustrated with respect to different types of complex real-world networks, namely the US air transportation network, the protein-protein interactions of the yeast Saccharomyces cerevisiae and the Roget thesaurus networks. The obtained singular motifs possessed unique functional roles in the networks. Three classic theoretical network models were also investigated, with the Barabasi-Albert model resulting in singular motifs corresponding to hubs, confirming the potential of the approach. Interestingly, the number of different types of singular node motifs as well as the number of their instances were found to be considerably higher in the real-world networks than in any of the benchmark networks.

ON CLOSED GEODESICS IN THE LEAF SPACE OF SINGULAR RIEMANNIAN FOLIATIONS

In this paper we prove the existence of closed geodesics in the leaf space of some classes of singular Riemannian foliations (s.r.f.), namely s.r.fs. that admit sections or have no horizontal conjugate points. We also investigate the shortening process with respect to Riemannian foliations.

Desingularization of singular Riemannian foliation

Let F be a singular Riemannian foliation on a compact Riemannian manifold M. By successive blow-ups along the strata of F we construct a regular Riemannian foliation (F) over cap on a compact Riemannian manifold (M) over cap and a desingularization map (rho) over cap : (M) over cap -> M that projects leaves of (F) over cap into leaves of F. This result generalizes a previous result due to Molino for the particular case of a singular Riemannian foliation whose leaves were the closure of leaves of a regular Riemannian foliation. We also prove that, if the leaves of F are compact, then, for each small epsilon > 0, we can find (M) over cap and (F) over cap so that the desingularization map induces an epsilon-isometry between M/F and (M) over cap/(F) over cap. This implies in particular that the space of leaves M/F is a Gromov-Hausdorff limit of a sequence of Riemannian orbifolds {((M) over cap (n)/(F) over cap (n))}.
