Atuação do enfermeiro na estratégia de atenção integrada às doenças prevalentes na infância

This study aimed to describe nurses' actions in the strategy of Integrated Management of Childhood Illness in the city of Natal, Rio Grande do Norte. This is a qualitative study with descriptive approach. The universe consisted of nurses from the Family Health Strategy, totaling 16 participants. For the research project was submitted for approval by the Ethics Committee of the Universidade Federal do Rio Grande do Norte, obtaining Opinion No. 187/2012. Data were obtained in two ways: a questionnaire survey to profile the training of nurses and an interview guided by a structured interview. Interviews were treated in the light of analysis of thematic category Bardin. The results showed the central thematic study "Integrated Management of Childhood Illness in the context of nursing activities" category and three analyzes: "Understanding the Integrated Management of Childhood Illness", "Difficulties invibializam use IMCI "and" Working conditions for nurses in the Integrated Management of Childhood Illness. " It is observed that nurses consider the Integrated Management of Childhood Illness useful, effective and important to keep sick children within the logic curative. However disregard the character of health promotion and disease prevention thereof. It was found that the participants still hold the attendance of crinaças within the biomedical model and that these same professionals are subjected to increasingly precarious working conditions and unhealthy due to lack of human and material resources. It was found that the interviewees do not follow the protocols of strategy because of barriers related to prescription medications by nurses, the medical, the lack of incentives, training and supervision by the municipal health and the Regional Nursing Council

Supervisório Inteligente de Processos na Idústria do Petróleo e Gás :Aplicação em uma Coluna de Destilação Simulada Integrada a Instrumentação Real

The need to implement a software architecture that promotes the development of a SCADA supervisory system for monitoring industrial processes simulated with the flexibility of adding intelligent modules and devices such as CLP, according to the specifications of the problem, it was the motivation for this work. In the present study, we developed an intelligent supervisory system on a simulation of a distillation column modeled with Unisim. Furthermore, OLE Automation was used as communication between the supervisory and simulation software, which, with the use of the database, promoted an architecture both scalable and easy to maintain. Moreover, intelligent modules have been developed for preprocessing, data characteristics extraction, and variables inference. These modules were fundamentally based on the Encog software

Equalização neural aplicada a sistemas com modulação bidimensional em fibra óptica

Nowadays, optic fiber is one of the most used communication methods, mainly due to the fact that the data transmission rates of those systems exceed all of the other means of digital communication. Despite the great advantage, there are problems that prevent full utilization of the optical channel: by increasing the transmission speed and the distances involved, the data is subjected to non-linear inter symbolic interference caused by the dispersion phenomena in the fiber. Adaptive equalizers can be used to solve this problem, they compensate non-ideal responses of the channel in order to restore the signal that was transmitted. This work proposes an equalizer based on artificial neural networks and evaluates its performance in optical communication systems. The proposal is validated through a simulated optic channel and the comparison with other adaptive equalization techniques

Diagnóstico de descarga de cátodo oco de ar e pós-descarga Ar N2 por espectroscopia de emissão óptica e espectrometria de massa

Many applications require that the plasma discharge is produced apart from the surface to be processed, thus preventing damage caused by bombardment and/or plasma radiation. In the post-discharge regime in various applications thermally sensitive materials can be used. In this work, active species produced by discharge and post-discharge hollow cathode were diagnosed by optical emission spectroscopy and mass spectrometry. The discharge was produced with the gases Ar and Ar - N2 gas flow ranging from 1 to 6 cm3/min and electric current between 150 to 600 mA. It was estimated that the ion density inside the hollow cathode, with 2 mm diameter ranged between 7.71 and 14.1 x 1015 cm-3. It was observed that the gas flow and the electric current changes the emission intensity of Ar and N2 species. The major ionic species detected by quadrupole mass spectrometry were Ar+ and N2+. The ratio of optical emission intensities of N2(1 +)/Ar(811 nm) was related to the partial pressure of N2 after the hollow cathode discharge at low pressure

História da ciência como estratégia didática no ensino médio: um breve olhar de conteúdos da óptica

From a critique of aspects of the current teaching of physics, we propose in this paper an investigation into the conceptions of Nature of Science (NOS) submitted by students from the high school level, as well as the inclusion of discussions about some elements of NOS, through the History and Philosophy of Science, understanding them as facilitating strategy for more effective learning of Physics and, more specifically, the contents of optics. Based on the historical period corresponding to Greek antiquity to the mid-nineteenth century, built and applied a teaching unit to a high school class at the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) Ipanguaçu campus. Our teaching unit involved the reading and interpretation of texts with historical content, observation and assembling five experimental activities, among other activities. Data analysis occurred through questionnaires investigative applied before and after the completion of the teaching unit, as well as questionnaires for content present in the texts. Although not significant, the results indicated that the application of the teaching unit allowed the (re) construction of some conceptions about NOS targets students present in our work, and contribute to a better learning content and greater optical science approach and its nature

O ensino de óptica no nível fundamental: uma proposta de ensino aprendizagem contextualizada para a oitava série

This dissertation presents the investigation and possible interference in the current teaching of physics, specially of optics, in the eighth grade/ ninth year / fourth cycle of junior high school. The context of the current science teaching is also presented. Besides, the following aspects are discussed: the preparation of the eighth grade teachers, their professional needs, the pedagogical practices and the theoreticmethodological difficulties faced by them. Another important issue in Science Teaching, which is also discussed in this dissertation, is the need for an efficient scientific literacy so that the citizen may express value judgment about Science and Technology issues. The data about the context were gathered from questionaires answered by the teachers. In value of this information, lesson plans were elaborated and implemented. The goal was to point out alternatives for the development of a teaching-learning evaluation which would be both pleasant for the teachers in relation to the implemented methodology, end meaningful for the students by adding elements such as: interdisciplinary approach, contextualization and preparation by competences. Furthermore it was carried out a deeper analysis of the Brazilian curriculum references (LDB, DCN, PCN, RCB) and content aspects (concepts, procedures e attitudes) to be executed by that branch of human knowledge, aiming at a really Contextualized Science Teaching, qualified and pleasant for the eighth grade level. It is also presented in this paper the profile or the Professional which teach this level at state public schools in Russas, state of Ceará, Vale do Jaguaribe Region. The efficacy of the lesson plans were also analysed by using evaluation procedures with the eighth grade students of the following schools: CAIC Senador Carlos Jereissati and EEF Manuel Matoso Filho, from which the concepts acquired during the implementation of the classes became evident in the students

Uma proposta de ensino e aprendizagem de Língua Inglesa integrada ao uso das TICS para o desenvolvimento da autonomia dos aprendizes

This study focuses on the teaching and learning of English based on a new theoretical perspective concerning the Zone of Proximal Development (ZPD), which points to the apprehension of metacognitive processes as the way to reach learning autonomy. The theoretical set underline this study is those of a new pedagogy based on the symbiosis of Bruner‟s (2002) and Freire‟s (2009) concepts and in the metacognitive theory. In a social context dominated by the Communication and Information Technologies (CIT), the integration between teacher and learners with the support of the internet has been used as the way to operationalize this new emergent proposal of the theoretical perspectives. The analyses have been conducted through Systemic and Integral Action Research. The results at the end of this study corroborate our hypothesis that the enlargement of spontaneous knowledge of the learners can facilitate the understanding of scientific concepts, stimulating their metacognition and thus promoting their autonomy.

Abordando o ensino de óptica através da construção de telescópios

A proposta deste trabalho é a construção artesanal de um telescópio refletor do tipo Newtoniano relacionando conteúdos abordados na disciplina de óptica, como a formação de imagens em lentes e espelhos, aberrações esféricas e cromáticas, interferência e difração, com cada fase do processo de construção. Com o aparelho construído é possível abordar a fotografia lunar e planetária com alta resolução e sua utilização por alunos do curso de Licenciatura em Física já demonstra ser um grande incentivo à contemplação do céu e à compreensão de muitos fenômenos físicos, com ocorrências de eclipses, formação das marés, estações do ano, etc, que geralmente são pouco abordados nas escolas de Ensino Fundamental e Médio. de acordo com diagnóstico realizado pelos alunos de graduação em algumas escolas do município de Bauru, verificou-se que a única abordagem de astronomia é apenas em relação ao sistema solar, especificamente órbitas planetárias, nas disciplinas de Física ou Geografia. Além do telescópio, a utilização de animações produzidas por alunos de graduação também pode ser considerada como uma ferramenta eficiente no ensino de astronomia, principalmente para alunos de Ensino Fundamental.

Caracterização citoarquitetônica, neuroquímica e de aferência óptica do complexo parabraquial do sagui (Callithrix jacchus)

The parabrachial complex (PB) is an area of the brainstem responsible for the processing and transmission of essential physiologic information for the survival of the organisms. This region is subdivided in approximately nine subregions, considering morphology, cytoarchitectural and functional characteristic. Its neurons have an extensive network of connections with other regions of the nervous system. The objective in this work was to map the retinal projection to the PB and make a citoarchitectonic and neurochemical characterization of this region in the common marmoset (Callithrix jacchus), a primate of the New World. The retinal projections were mapped by anterograde transport of the choleric toxin subunit b (CTb). The citoarchitecture was described through the Nissl method, and the neurochemical characterization was made through immunohistochemical technique to the some neurotransmitters and neuroactives substances present in this neural center. In marmoset PB, in the coronal sections labeled by Nissl method, we found a similar pattern to that evidenced in other animal species. The immunoreactivity against CTb was verified in the PBMv in fibers/terminal, characterizing such as retinal innervations in this area. The immunohistochemical technique reveled that the PB contain cells, fibers and/or terminals immunoreactives to the neuronal nuclear protein, Choline acetyl transferase, nitric oxide synthase, serotonin, enkephalin, substance P, Calcium-binding proteins (calbindin, calretinin e parvalbumin), and glial fibrillary acidic protein. The histochemical technique reveled cells and fibers NADPH-diaphorase reactive. Each one of those substances presented a characteristic pattern of demarcation in PB, and some serve as specific markers of subregions

Espectrometria de emissão óptica com plasma indutivamente acoplado aliada à quimiometria na determinação de íons metálicos no molusco Mytella falcata para discriminação de estuários potiguares

This work examined the possibility of using mussel Mytella falcata as bioindicator sample to detect metal ions in several estuaries potiguares, since species substances that accumulate in their tissues due to its characteristics filter feeders have been used for environmental monitoring. The chemometrics by principal components analysis was used to reduce the size of the original data in order to establish a pattern of distribution of metal ion. Samples were collected at three different points in the estuaries Curimataú, Guaraíra-Papeba, Potengi, Galinhos-Guamaré and Piranhas-Assu having been marked with the location using GPS (Global Positioning System). The determination of humidity content and digestion of the samples were performed using methods described in the Compendium of analytical standards of the Institute Adofo Lutz (2005) and the determination of metal ions of the elements Al, Ba, Cd, Cr, Cu, Mn, Ni, Pb, Sn and Zn were performed by optical emission spectrometry with inductively coupled plasma as described by USEPA method 6010C. The results show that it is possible to use this molluscum Mytella falcata in the estuaries of Rio Grande do Norte for the determination of metal ions. The data were subjected to principal components analysis (PCA) which enabled us to verify the distribution pattern of the metal ions studied in several estuaries potiguares and group them according to the metal ions in common with and relate them to the activities in each region

Condicionamento estrutural das zonasa de cisalhamento da região de Forquilha, domínio Ceará Central: uma abordagem integrada de sensoriamento remoto e geologia estrutural

The studied region, named Forquilha and localized in northwestern Central Ceará domain (northern portion of Borborema Province), presents a lithostratigraphic framework constituted by paleoproterozoic metaplutonics, metasedimentary sequences and neoproterozoic granitoids. The metasedimentary rocks of Ceará group occupy most part of the area. This group is subdivided in two distinct units: Canindé and Independência. Canindé unit is represented basically by biotite paragneisses and muscovite paragneisses, with minor metabasic rocks (amphibolite lens). Independência sequence is composed by garnetiferous paragneisses, sillimanite-garnet-quartz-muscovite schists and quartz-muscovite schists, pure or muscovite quartzites and rare marbles. At least three ductile deformation events were recognized in both units of Ceará group, named D1, D2 and D3. The former one is interpreted as related to a low angle tangential tectonics which mass transport is southward. D2 event is marked by the development of close/isoclinal folds with a N-S oriented axis. Refolding patterns generated by F1 and F2 superposition are found in several places. The latest event (D3) corresponds to a transcurrent tectonics, which led to development of mega-folds and several shear zones, under a transpressional regime. The mapped shear zones are Humberto Monte (ZCHM), Poço Cercado (ZCPC) and Forquilha (ZCF). Digital image processing of enhanced Landsat 7-ETM+ satellite images, combined with field data, demonstrate that these penetrative structures are associated with positive and negative geomorphologic patterns, distributed in linear and curvilinear arrangements with tonal banding, corresponding to the ductile fabric and to crests. Diverse color composites were tested and RGB-531 and RGB-752 provided the best results for lineament analysis of the most prominent shear zones. Spatial filtering techniques (3x3 and 5x5 filters) were also used and the application of Prewitt filters generated the best products. The integrated analysis of morphological and textural aspects from filtered images, variation of tonalities related to the distribution of geologic units in color composites and the superposition over a digital elevation model, contributed to a characterization of the structural framework of the study area. Kinematic compatibility of ZCHM, ZCPC, ZCF shear zones, as well as Sobral-Pedro II (ZCSPII) shear zone, situated to the west of the study area, was one of the goal of this work. Two of these shear zones (ZCHM, ZCPC) display sinistral movements, while the others (ZCSPII, ZCF) exhibit dextral kinematics. 40Ar/39Ar ages obtained in this thesis for ZCSPII and ZCPC, associated with other 40Ar/39Ar data of adjacent areas, indicate that all these shear zones are related to Brasiliano orogeny. The trend of the structures, the opposite shear senses and the similar metamorphic conditions are fitted in a model based on the development of conjugate shear zones in an unconfined transpression area. A WNW-ESE bulk shortening direction is infered. The geometry and kinematic of the studied structures suggest that shortening was largely accommodated by lateral extrusion, with only minor amounts of vertical stretch

Elementos figurados da hemolinfa de Dermatobia hominis (Diptera: Cuterebridae): caracterização ao nível de microscopia óptica, em larvas do 2o. e 3o. instares

Foram examinados os hemócitos de larvas do 2º (L2) e 3º(L3) instares de Dermatobia hominis em nível de microscopia óptica e comparados com os de outras espécies encontradas na literatura. Nas L2 e em L3 com peso de até 200mg foram encontrados cinco tipos: Pro-hemócitos, Plasmatócitos, Vermiformes, Oenocitóides e Esfoliativas. A medida em que as L3 foram-se tornando mais idosas apareceram em seqüência os Granulócitos e Adipohemócitos, sendo raro encontrar-se Pro-hemócitos em L3 com peso acima de 500mg. Tipos intermediários entre Pro-hemócitos e Plasmatócitos e entre Granulócitos e Adipohemócitos também foram encontrados, fazendo-se supor que pro-hemócitos dão origem ao Plasmatócito e que este dá origem ao Granulócito que pode acumular grãos de lipídeos transformando-se em Adipohemócito. O Oenocitóide parece ter origem diferente dos demais tipos. Não foram encontradas formas transicionais entre Plasmatócito fusiforme e Vermiforme típica conforme aparece na literatura para algumas espécies. Embora sem ter característica de hemócitos, as células Esfoliativas são elementos que aparecem nos dois instares estudados.

O presente trabalho tem como objetivo realizar um estudo de anatomia foliar por meio de microscopia óptica e de microscopia eletrônica de varredura em Mentha spicata L. e Mentha spicata X suaveolens, caracterizando histologicamente a lâmina foliar. Secções transversais e paradérmicas da região mediana do limbo foliar mostraram a presença de epiderme unisseriada, coberta por uma fina camada de cutícula, apresentando tricomas glandulares do tipo capitado e peltado e não glandulares unisseriados multicelulares, não ramificados. O mesofilo de ambas as espécies é dorsiventral, com parênquima paliçádico uniestratificado, com células alongadas e rico em inclusões citoplasmáticas. O parênquima lacunoso é formado por três a quatro camadas de células irregulares. Os tricomas capitados presentes são classificados como do tipo I, e apresentam-se com uma célula basal, uma célula peduncular e uma grande célula apical, cujo formato varia de circular a piriforme. Os tricomas peltados consistem de uma célula basal, uma célula peduncular curta, larga e unicelular, com paredes externas cutinizadas e uma cabeça grande multicelular com 12 células secretoras, distribuídas radialmente em dois círculos concêntricos, o central com 4 células e o externo com 8 células, as quais acumulam o produto da secreção em uma cavidade entre a cutícula e as células secretoras; o pé do tricoma glandular está inserido em 11 células epidérmicas. Há predominância de tricomas capitados em relação aos tricomas peltados em ambas as espécies de Mentha.
