Atenção à saúde da pessoa idosa na estratégia saúde da família no município de Santo Antônio/RN: um estudo de caso

According to demographic estimates, by the year 2025 Brazil will be the sixth country in the world in number of elderly. For this reason, it is a purpose of public policies to help people to reach that age being healthier. The current health care model of health surveillance through the Family Health Strategy (EFS, in portuguese) is configured as a gateway into the care of the elderly in the Unified Health System (SUS, in portuguese). It is also an area of development of practices to promote health, prevention and control of chronic nondegenerative diseases. The aim of this study was to analyze the health care of the elderly provided by ESF professionals for the achievement of a full care. The study is descriptive case study with a quantitative approach, performed in the city of Santo Antônio/RN. The population included all health professionals, who are FHS members of the city that agreed to participate of the survey, a total of 80 professionals. Data were collected using a structured questionnaire, having mostly closed questions and divided into two parts: one containing sociodemographic information of health professionals and vocational training and the other, the activities carried on by the professionals in senior care, being analyzed from a database tabulated in a spreadsheet and discussed according to the descriptive statistics in tables, graphs and charts using frequencies, medians and values of central tendency. It was verified a predominance of professionals who finished highschool, mostly female, aged from 30 to 34 years old, with training completed in the last 10 years, without being graduated in the field of geriatrics or gerontology and mostly without training in gerontology. Family members and caregivers were the components of the social support network most identified by the professionals (66.3%).The elderly access to the Family Health Basic Unit was considered by83.8% of professionals as the most important factor that interferes in the activities of health care of the elderly. Considering the inclusion of the family in care: 98.8% of professionals consider the family as one of the goals of care, but 82.5% assist the family to know their role and participate in the care of the elderly, emphasizing that no professional makes use of tools for evaluating the functionality of the family. Regarding the actions taken to assist the elderly, 91.25% have home visits program to the elderly, 88.75% use the host program; 77.5% know the habits of life, cultural, ethical and religious values of the elderly, their families and their community ;51.25% complement the activities through intersectoral actions, 50%participate in groups of living with the elderly; 33.75% keeps track and maintain updated the health information of the elderly; 11.25% of the professionals perform the Single Therapy Planning (PTS, in portuguese) and few implement the actions to promote health according to PTS; there is a deficit in the number of professional categories in the identification and monitoring of the frail older people in their households. It is concluded that the health care of the elderly developed by ESF professionals differs among the professional categories. It was identified weaknesses in the promotion of an active and healthy aging and also in the establishment of an integrated and full care of the elderly. It is recommended the adoption of permanent educational activities by the City Management, initially for ESF professionals in the the perspective of the guidelines of the National Policy of Health Care for the Elderly and later to the other professionals that are part of the health care network of the elderly, at all levels of care in the city for the development of strategies and practices that promote the improvement of the quality of healthcare for the elderly, expecting concrete and effective results in terms of promoting health within Brazilian reality

Uma contribuição à definição de indicadores de desempenho de instituições federais de educação tecnológica do Brasil na abordagem do balanced scorecard

This Master of Science Thesis deals with a study on applying the BSC Balanced Scorecard to assess the performance of Federal Centers for Technological Education Institution in Brazil, the CEFET s (Centro Federal de Educação Tecnológica), government organizations non for profit. It s accomplished a literature review in order to understand the BSC and its application to non for profit organizations and as a main result it is proposed a BSC conceptual model with an inversion of the main BSC perspective from financial to customer/society. Taking the FORPLAN/CONCEFET performance indicators matrix it is developed a set of performance indicators for the two tops perspective in the conceptual model proposed five for customer/society perspective and three for financial/budget perspective. A field survey with ten CEFET s General Directors is conducted to validate the indicators and assess the perception of the Directors on the hierarchy of the conceptual model, and a hierarchy among the indicators as well. The main results suggests that the indicators are validated, that most of the Directors support the hierarchy presented in the conceptual model but 30% of them have a traditional model with financials coming first. In terms of indicator hierarchy, there s a slight priority for the student unitary cost among the financial perspective indicators, and a relative balance among the customer/society perspective indicators

Análise e projeto de superfícies seletivas de frequência com elementos pré-fractais para aplicações em comunicações indoor

In this thesis, a frequency selective surface (FSS) consists of a two-dimensional periodic structure mounted on a dielectric substrate, which is capable of selecting signals in one or more frequency bands of interest. In search of better performance, more compact dimensions, low cost manufacturing, among other characteristics, these periodic structures have been continually optimized over time. Due to its spectral characteristics, which are similar to band-stop or band-pass filters, the FSSs have been studied and used in several applications for more than four decades. The design of an FSS with a periodic structure composed by pre-fractal elements facilitates the tuning of these spatial filters and the adjustment of its electromagnetic parameters, enabling a compact design which generally has a stable frequency response and superior performance relative to its euclidean counterpart. The unique properties of geometric fractals have shown to be useful, mainly in the production of antennas and frequency selective surfaces, enabling innovative solutions and commercial applications in microwave range. In recent applications, the FSSs modify the indoor propagation environments (emerging concept called wireless building ). In this context, the use of pre-fractal elements has also shown promising results, allowing a more effective filtering of more than one frequency band with a single-layer structure. This thesis approaches the design of FSSs using pre-fractal elements based on Vicsek, Peano and teragons geometries, which act as band-stop spatial filters. The transmission properties of the periodic surfaces are analyzed to design compact and efficient devices with stable frequency responses, applicable to microwave frequency range and suitable for use in indoor communications. The results are discussed in terms of the electromagnetic effect resulting from the variation of parameters such as: fractal iteration number (or fractal level), scale factor, fractal dimension and periodicity of FSS, according the pre-fractal element applied on the surface. The analysis of the fractal dimension s influence on the resonant properties of a FSS is a new contribution in relation to researches about microwave devices that use fractal geometry. Due to its own characteristics and the geometric shape of the Peano pre-fractal elements, the reconfiguration possibility of these structures is also investigated and discussed. This thesis also approaches, the construction of efficient selective filters with new configurations of teragons pre-fractal patches, proposed to control the WLAN coverage in indoor environments by rejecting the signals in the bands of 2.4~2.5 GHz (IEEE 802.11 b) and 5.0~6.0 GHz (IEEE 802.11a). The FSSs are initially analyzed through simulations performed by commercial software s: Ansoft DesignerTM and HFSSTM. The fractal design methodology is validated by experimental characterization of the built prototypes, using alternatively, different measurement setups, with commercial horn antennas and microstrip monopoles fabricated for low cost measurements

Arranjo de antenas de microfita com substrato anisotrópico com patch supercondutor e aplicações em nanotecnologia

The main objective in this work is the analysis of resonance frequency microstrip structures with glass fiber and electromagnetic band gap (EBG/PBG) substrate and analysis of microstrip antennas with rectangular patch of superconductor of high critical temperature (HTS). In this work was used the superconductors YBCO (critical temperature of 90K), SnBaCaCuOy (critical temperature of 160K), and Sn5InCa2Ba4Cu10Oy (critical temperature of 212K) with results in Gigahertz and Terahertz. Was used microstrip antennas arrays planar and linear phase and linear phase planar with patch with superconductor. It presents a study of the major theories that explain superconductivity. In phase arrays were obtained the factors arrays for such configurations, and the criteria of phase and spacing between the elements compound in the array, which were examined in order to get a main lobe with high directivity and high gain. In the analysis we used the method of Transverse Transmission Line (TTL) used in domain of the Fourier Transform (FTD). The LTT is a full wave method, which obtains the electromagnetic field in terms of the components transverse of the structure. The addition of superconductive patch is made using the boundary condition resistive complex. Results are obtained resonance frequency as a function of the parameters of the antenna, radiation patterns of the E and H Planes, for the phase antenna arrays in linear and planar configurations, for different values of the phase and the spacing between elements

VCO Banda Larga Integrado para Receptor a Cinco Portas

This work presents an wideband ring VCO for cognitive radio five-port based receivers. A three-stage differential topology using transmission gate was adopted in order to maintain wide and linear tuning range and a low phase-noise. Monte-Carlo analysis were performed for phase-shift response of individual stages, which is an important figure of merit in five-port works. It was observed a fairly linear correlation between control voltage and oscillation frequency in the range between 200 MHz and 1800 MHz. The VCO was preliminarily designed for IBM 130nm CMOS technology

Arranjos Log-Periódicos Compactos em Microfita com Elementos Fractais de Koch

This work aims to present how the application of fractal geometry to the elements of a log-periodic array can become a good alternative when one wants to reduce the size of the array. Two types of log-periodic arrays were proposed: one with fed by microstrip line and other fed by electromagnetic coupling. To the elements of these arrays were applied fractal Koch contours, at two levels. In order to validate the results obtained some prototypes were built, which were measured on a vector network analyzer and simulated in a software, for comparison. The results presented reductions of 60% in the total area of the arrays, for both types. By analyzing the graphs of return loss, it was observed that the application of fractal contours made different resonant frequencies appear in the arrays. Furthermore, a good agreement was observed between simulated and measured results. The array with feeding by electromagnetic coupling presented, after application of fractal contours, radiation pattern with more smooth forms than the array with feeding by microstrip line

Análise de onda completa de superfície seletiva em freqüência do tipo anteparo duplo

This work presents a theoretical analysis and numerical and experimental results of the scattering characteristics of frequency selective surfaces, using elements of type patch perfectly conductor. The structures are composed of two frequency selective surfaces on isotropic dielectric substrates cascaded, separated by a layer of air. The analysis is performed using the method of equivalent transmission line in combination with the Galerkin method, to determine the transmission and reflection characteristics of the structures analyzed. Specifically, the analysis uses the impedance method, which models the structure by an equivalent circuit, and applies the theory of transmission lines to determine the dyadic Green's function for the cascade structure. This function relates the incident field and surface current densities. These fields are determined algebraically by means of potential incidents and the imposition of the continuity of the fields in the dielectric interfaces. The Galerkin method is applied to the numerical determination of the unknown weight coefficients and hence the unknown densities of surface currents, which are expanded in terms of known basis functions multiplied by these weight coefficients. From the determination of these functions, it becomes possible to obtain numerical scattered fields at the top and bottom of the structures and characteristics of transmission and reflection of these structures. At work, we present numerical and experimental results for the characteristics of transmission and reflection. Comparisons were made with other results presented in literature, and it was observed a good agreement in the cases presented suggestions continuity of the work are presented

Desenvolvimento e testes de software de um receptor de GPS para uso espacial

Spacecraft move with high speeds and suffer abrupt changes in acceleration. So, an onboard GPS receiver could calculate navigation solutions if the Doppler effect is taken into consideration during the satellite signals acquisition and tracking. Thus, for the receiver subject to such dynamic cope these shifts in the frequency signal, resulting from this effect, it is imperative to adjust its acquisition bandwidth and increase its tracking loop to a higher order. This paper presents the changes in the GPS Orion s software, an open architecture receiver produced by GEC Plessey Semiconductors, nowadays Zarlink, in order to make it able to generate navigation fix for vehicle under high dynamics, especially Low Earth Orbit satellites. GPS Architect development system, sold by the same company, supported the modifications. Furthermore, it presents GPS Monitor Aerospace s characteristics, a computational tool developed for monitoring navigation fix calculated by the GPS receiver, through graphics. Although it was not possible to simulate the software modifications implemented in the receiver in high dynamics, it was observed that the receiver worked in stationary tests, verified also in the new interface. This work also presents the results of GPS Receiver for Aerospace Applications experiment, achieved with the receiver s participation in a suborbital mission, Operation Maracati 2, in December 2010, using a digital second order carrier tracking loop. Despite an incident moments before the launch have hindered the effective navigation of the receiver, it was observed that the experiment worked properly, acquiring new satellites and tracking them during the VSB-30 rocket flight.

Classificação Automática de Modulação Digital com uso de Correntropia para Ambientes de Rádio Cognitivo

Modern wireless systems employ adaptive techniques to provide high throughput while observing desired coverage, Quality of Service (QoS) and capacity. An alternative to further enhance data rate is to apply cognitive radio concepts, where a system is able to exploit unused spectrum on existing licensed bands by sensing the spectrum and opportunistically access unused portions. Techniques like Automatic Modulation Classification (AMC) could help or be vital for such scenarios. Usually, AMC implementations rely on some form of signal pre-processing, which may introduce a high computational cost or make assumptions about the received signal which may not hold (e.g. Gaussianity of noise). This work proposes a new method to perform AMC which uses a similarity measure from the Information Theoretic Learning (ITL) framework, known as correntropy coefficient. It is capable of extracting similarity measurements over a pair of random processes using higher order statistics, yielding in better similarity estimations than by using e.g. correlation coefficient. Experiments carried out by means of computer simulation show that the technique proposed in this paper presents a high rate success in classification of digital modulation, even in the presence of additive white gaussian noise (AWGN)

Estudo de Superfícies Seletivas de Frequência com o Uso de Inteligência Computacional

The main objective of this work is to optimize the performance of frequency selective surfaces (FSS) composed of crossed dipole conducting patches. The optimization process is performed by determining proper values for the width of the crossed dipoles and for the FSS array periodicity, while the length of the crossed dipoles is kept constant. Particularly, the objective is to determine values that provide wide bandwidth using a search algorithm with representation in bioinspired real numbers. Typically FSS structures composed of patch elements are used for band rejection filtering applications. The FSS structures primarily act like filters depending on the type of element chosen. The region of the electromagnetic spectrum chosen for this study is the one that goes from 7 GHz to 12 GHz, which includes mostly the X-band. This frequency band was chosen to allow the use of two X-band horn antennas, in the FSS measurement setup. The design of the FSS using the developed genetic algorithm allowed increasing the structure bandwidth

Variação do tamanho de sementes de plantas daninhas e sua influência nos padrões de emergência das plântulas

Estudos relacionados ao tamanho de sementes e sua influência no processo germinativo de plantas daninhas são necessários devido à grande importância das espécies e à escassez de informações relacionadas à produção de sementes dessas plantas. Dessa forma, este trabalho objetivou estudar a variação do tamanho de sementes de 12 espécies de plantas daninhas e a emergência de duas dessas espécies semeadas em diferentes profundidades. Foi mensurado o peso unitário de 200 sementes por espécie de planta daninha selecionada e estabelecidas curvas de distribuição das frequências não acumuladas para o peso das sementes das espécies, utilizando-se o modelo de Gompertz. Após a classificação por tamanho (pequenas, médias e grandes), sementes de Ipomoea purpurea e Brachiaria decumbens foram semeadas em campo, em canteiros de 1,2 m², em diferentes profundidades no solo (2, 4, 6, 8 e 10 cm) de cada tratamento (profundidade); efetuaram-se quatro repetições. de maneira geral, no primeiro estudo, os resultados indicaram que não há como se referir ao peso de sementes das espécies de plantas daninhas estudadas considerando-se apenas a média dessa característica, devido à variação que pode ser encontrada. Essa grande variação no tamanho das sementes pode estar associada, também, a variações nos padrões de emergência, o que foi verificado no segundo estudo para a espécie I. purpurea. O índice de velocidade de emergência para I. purpurea foi maior para 4 cm de profundidade nas sementes pequenas, 8 cm nas sementes médias e de 6 a 10 cm de profundidade nas sementes grandes.

Levantamento da infestação de plantas aquáticas em Porto Primavera antes do enchimento final do reservatório

O objetivo deste trabalho foi identificar as plantas aquáticas e os níveis de infestação de cada espécie em Porto Primavera antes do enchimento final do reservatório. Foram avaliados todos os focos de vegetação aquática no reservatório (72 pontos), sendo os pontos demarcados com um aparelho de GPS. As espécies foram identificadas e estimouse visualmente (tamanho da área) a distribuição proporcional das plantas no foco de infestação. Após a identificação, foram encontradas 18 espécies de plantas aquáticas vegetando no reservatório, das quais foram determinadas a frequência de espécie de planta aquática e a distribuição dentro do sistema de geração de energia. As espécies encontradas no reservatório foram: Eichhornia crassipes, Eichhornia azurea, Pistia stratiotes, Paspalum repens, Cyperus brevifolius, Paspalum conspersum, Echinochloa polystachya, Egeria densa, Egeria najas, Polygonum hidropiperoides, Polygonum lapathifolium, Alternanthera philoxeroides, Eleocharis sellowiana, Nymphaea ampla, Pontederia cordata, Salvinia auriculata, Salvinia rotundifolia e Typha angustifolia. As maiores frequências relativas foram observadas em: E. azurea (36,11%), E. crassipes (16,67%), P. stratiotes (13,89%), S. auriculata (13,89%), C. brevifolius (11,11%) e P. lapathifolium (6,94%).

Análise comparativa de traduções do Cântico dos Cânticos

Observam-se especialmente as divergências entre as duas, no que diz respeito ao erotismo presente no poema, e analisando as suas prováveis razões discursivas. Não se visa aqui a produção de uma nova tradução, mas a comparação e o comentário das escolhas tradutórias em determinados excertos das obras selecionadas. A argumentação desenvolvese através dos seguintes encaminhamentos: após a apresentação do objeto de estudo com o debate que sempre o acompanha acerca das polêmicas de datação e autoria, passa-se à exposição do problema do qual se ocupa a hipótese, assim como os objetivos e os parâmetros metodológicos que regeram a elaboração desta dissertação. Consecutivamente, elencam-se os pressupostos teóricos que emolduram as análises propostas, aborda-se também a sexualidade segundo a religião contemporânea (por se tratar de um livro ao qual se agregou valor religioso) nas instituições que adotaram o Cântico dos Cânticos, a saber: o judaísmo e o cristianismo católico e protestante, assim como o processo possivelmente efetuado durante essa adoção quanto ao enviesamento interpretativo e à atribuição autoral: visa-se compreender as razões da incongruência causada pelo sexo que permeia o texto em questão relativamente à religiosidade contemporânea, e especula-se sobre a sua canonização, considerando como esse desencaixe pode ter mudado o curso da sua exegese tradicional para a alegoria que se tornou a sua leitura majoritária, inclusive engendrando a atribuição tradicional da sua suposta origem. Somente então se dá início à análise comparativa das duas traduções, a fim de se constatar a provável existência dum viés discursivo transparecente das formas como cada uma destas obras verteu as porções do texto-fonte, para o português, que continham marcas de erotismo, observando se respeitaram ou não as leituras tradicionais que insuflaram no texto o seu pendor alegórico de caráter religioso

Noções básicas de variabilidade da frequência cardíaca e sua aplicabilidade clínica

O sistema nervoso autônomo (SNA) desempenha um papel importante na regulação dos processos fisiológicos do organismo humano tanto em condições normais quanto patológicas. Dentre as técnicas utilizadas para sua avaliação, a variabilidade da frequência cardíaca (VFC) tem emergido como uma medida simples e não-invasiva dos impulsos autonômicos, representando um dos mais promissores marcadores quantitativos do balanço autonômico. A VFC descreve as oscilações no intervalo entre batimentos cardíacos consecutivos (intervalos R-R), assim como oscilações entre frequências cardíacas instantâneas consecutivas. Trata-se de uma medida que pode ser utilizada para avaliar a modulação do SNA sob condições fisiológicas, tais como em situações de vigília e sono, diferentes posições do corpo, treinamento físico, e também em condições patológicas. Mudanças nos padrões da VFC fornecem um indicador sensível e antecipado de comprometimentos na saúde. Uma alta variabilidade na frequência cardíaca é sinal de boa adaptação, caracterizando um indivíduo saudável, com mecanismos autonômicos eficientes, enquanto que, baixa variabilidade é frequentemente um indicador de adaptação anormal e insuficiente do SNA, implicando a presença de mau funcionamento fisiológico no indivíduo. Diante da sua importância como um marcador que reflete a atividade do SNA sobre o nódulo sinusal e como uma ferramenta clínica para avaliar e identificar comprometimentos na saúde, este artigo revisa aspectos conceituais da VFC, dispositivos de mensuração, métodos de filtragem, índices utilizados para análise da VFC, limitações de utilização e aplicações clínicas da VFC.
