Corpo e poesia: para uma educação dos sentidos

In this research, we reflect on Body and Poetry: for an Education of the senses. This piece of work has as its objective the comprehension of the body and poetry s interlacement, for an education of the senses, starting from the experience of the Being in the world. With this purpose, we search to understand the poetic creation as the corporal transubstantiation by means of the senses, which is realized in the creative expression and manifests itself in the body language, opening ways to an education felt in the aesthetic experience. In order to comprehend the process of poetic creation, we rely on the phenomenological method of the lived world from Merleau-Ponty, philosophy, always opening forests of questionings and sprouting new doubts in search of other comprehensions about Poetry, Body and Education. These three phenomena were investigated by means of a reflection on my own life trajectory as a poet and Physical Education professor; identification and analysis of poets/reciters; sensitive experiences experience lived in Oficinas de Poesias (Poetry Workshops), held in seven public governmental schools of the State of Rio Grande do Norte and through a permanent dialogue with the works of Merleau-Ponty, Severino Antonio, Paul Zumthor, Petrucia Nóbrega, among other authors. Phenomenology and the sources investigated have permitted us to conclude that poetic creation is not a product of a divine inspiration, of a spirit come from over yonder, nor a hereditary gift, but poetry is created from a dialogue between the poet and the organic and cultural world, revealing at each experience undergone a new world of senses and meanings. It was possible to comprehend the poetic language as a synesthetic and performable manifestation, which ontologically reveals itself and hides itself at each experience, bringing new expressive clarities of the Being in the world. This piece of research has revealed us that poetry as a sensitive experience of the poetic state makes it possible a construction of a sensitive, glad and ludic knowledge for an education of the senses

Representações sociais do comportamento agressivo do homem sob a ótica da mulher em situação de violência

We aim to understand the social representations of man's aggressive behavior from the perspective of women in situations of domestic violence. This is a descriptive, exploratory and representational study, whose methodological approach falls into the qualitative category. We chose as a scenario for research, by the Reference Center for Citizen Women (CRMC), Natal / RN. The criteria for selection of participants were women who lived/live in situations of domestic violence, with affective or relationship bonding with the assailant, in psychological and emotional positions appropriated to the reality; that are being protected or assisted by the service listed above; whose aggressor is male. We adopted as data collection instruments: questionnaire, Drawing-Story (DE) and a field diary. For analysis of textual data, we decided to use the ALCESTE software conjugated to editing analyze and initial reading. Were investigated 20 women victims of domestic violence, whose author of the attacks was the husband/partner. We identified, from the respondents, that 70% (n = 14) of men with aggressive behavior also had a family history of violence and fragile family relationships. About the physical and emotional condition of the assailant at the time of violence, 50% (n = 10) of these men, regardless the use of alcohol, had often quarrelsome and/or nervous behavior, impatient and unpredictable humor facing a setback, worry or annoyance. Regarding the nature of violence, we observed that women were victims of all types of violence, however, the psychological prevailed in 100% of cases. The corpus "Men" has three classes, whose focuses are, respectively: resignation, denounce and violence/aggression, being possible categorizing them as well: Category 1: The imprisonment of women; Category 2: Violence and its meanings; Category 3: Breaking the violent cycle. We show that the social representations of man s aggressive behavior, from the women in situations of violence, are anchored in the social roles of men in family and society, becoming a dominant model of masculinity. It is aimed, on one hand, from the reproduction of what is already known and/or experienced by male aggressors in the family, as repetitions of behavior. And on the other, present themselves as a state of illness, addiction or psychopathy

Hanseníase: a implicação da educação em saúde para o autocuidado

A hanseníase é um problema de saúde em nível mundial devido principalmente ao seu potencial incapacitante. A estratégia de combate à doença adotada pelo Ministério de Saúde é o diagnóstico e tratamento precoces, prevenção e tratamento de incapacidades físicas e vigilância dos contatos domiciliares. Tudo isso fundamentado na educação em saúde como sustentáculo para compreensão do processo de adoecimento, da doença em si, sua aceitação e, principalmente, das ações de autocuidado para prevenção de sequelas. Nesse contexto, questiona-se: Qual a implicação da assistência de enfermagem focada na educação em saúde para o autocuidado em portadores de hanseníase? O objetivo geral desse estudo é avaliar os conhecimentos adquiridos pelos portadores de hanseníase sobre a doença, o tratamento e autocuidado abordados durante a consulta de enfermagem. Trata-se de um estudo exploratório-descritivo com abordagem qualitativa, realizado no Hospital Universitário Onofre Lopes. Respeitou a resolução 466/12 do Conselho Nacional de Saúde e foi aprovado pelo comitê de ética sob nº 387.769 e CAAE 17468213.0.0000.5537. Envolveu 14 portadores de hanseníase em tratamento no ambulatório de dermatologia do HUOL. Os dados foram coletados no período de 23 de setembro a 04 de novembro de 2013 por meio de entrevista semi-estruturada; e analisados a partir da analise de conteúdo de Bardin. Os resultados e discussões são apresentados através de um artigo, o qual atende os objetivos propostos, denominado O autocuidado realizado por portadores de hanseníase . Esse objetivou identificar as ações de autocuidado de portadores de hanseníase em uma unidade de referência a partir de três eixos temáticos emersos dos discursos dos sujeitos: 1.as complicações/sequelas da hanseníase conhecidas pelos portadores da doença; 2. as ações de autocuidado adotadas pelos portadores de hanseníase; 3. as possíveis contribuições de um grupo de autocuidado para os portadores de hanseníase. Constou-se aparente superficialidade no conhecimento dos pacientes sobre as complicações da hanseníase, como também, das ações de autocuidado realizadas por eles. Verificou-se também a importância da assistência de enfermagem ao portador de hanseníase, tanto na atenção primária, quanto nos demais níveis de complexidade 11 da assistência. Considera-se que o enfermeiro é um potencial colaborador da educação em saúde como alicerce para o controle e eliminação da hanseníase

A Produção mais Limpa como ferramenta em busca da sustentabilidade empresarial: um estudo de múltiplos casos em empresas do Estado do Rio Grande do Norte

This study aimed to assess the Cleaner Production CP as corporate sustainable tool, through the multiple case studies within companies from Rio Grande do Norte State. In order to achieve this goal a research methodology approach was set. The initial stage of the research methodology was based on a literature review on which it was observed that the CP can be linked with corporate sustainable once it prevents pollution and reduces the operational risks among employees, community and environment. In addition, CP can useful for companies position within competitive position as well as being applied to process, products and services. In order to observe these factors, CP was used within food industry (Company 1), textile industry (Company 2) and in a car dealer (Company 3). Regarding the results, Company 1 changed its raw material as well as implementing housekeeping (control use of water, energy and condensed milk). In Company 2, it was observed the three levels of CP. In other words, housekeeping (e.g. cutting process and manipulation of chemical products), changing technology (high pressure washing machine) and internal and external recycling. In addition, Company 3 considered only level 3 external recycling. As consequence, it was observed that can be applied either within industry as well as service sector. Unfortunately, it was not possible to observe any social gains on a monetary basis. This is due to limitations of the CP methodology and study complexity. Therefore, it was observed improvements regarding to social, environmental and economic areas. Nevertheless, it is necessary more commitment from top level management in order to consider CP like effective sustainable tool

Fatores que afetam a satisfação e a fidelidade do consumidor: um estudo com usuários de calçado esportivo (tênis), na Região Sul da cidade de Natal

This paper aims to investigate the factors that influence the satisfaction and fidelity of tennis´s users with the region southern city of Natal, capital of Rio Grande do Norte as the area of analyzing , using the national satisfaction index models as a tool to study. In this study was used the questionnaire as a tool for collecting data based on the new Norwegian customer satisfaction barometer model proposed by Johnson et. al. (2001). The data collection took place during the months of May and June 2008, when 450 tennis´s users were interviewed. The main results obtained by multiple regression analysis and logistic regression showed that the users' satisfaction with the tennis´s brand is influenced by the quality, comfort, material used in the manufacture and price, while fidelity is potentized by the image of the brand and the satisfaction degree with the user's tennis and with the brand of tennis.

As the processing of claims there was no direct influence on satisfaction and consumers fidelity due to the low number complaints

Metodologia para modelagem, validação e programação de controladores lógicos industriais usando statecharts básicos

Due of industrial informatics several attempts have been done to develop notations and semantics, which are used for classifying and describing different kind of system behavior, particularly in the modeling phase. Such attempts provide the infrastructure to resolve some real problems of engineering and construct practical systems that aim at, mainly, to increase the productivity, quality, and security of the process. Despite the many studies that have attempted to develop friendly methods for industrial controller programming, they are still programmed by conventional trial-and-error methods and, in practice, there is little written documentation on these systems. The ideal solution would be to use a computational environment that allows industrial engineers to implement the system using high-level language and that follows international standards. Accordingly, this work proposes a methodology for plant and control modelling of the discrete event systems that include sequential, parallel and timed operations, using a formalism based on Statecharts, denominated Basic Statechart (BSC). The methodology also permits automatic procedures to validate and implement these systems. To validate our methodology, we presented two case studies with typical examples of the manufacturing sector. The first example shows a sequential control for a tagged machine, which is used to illustrated dependences between the devices of the plant. In the second example, we discuss more than one strategy for controlling a manufacturing cell. The model with no control has 72 states (distinct configurations) and, the model with sequential control generated 20 different states, but they only act in 8 distinct configurations. The model with parallel control generated 210 different states, but these 210 configurations act only in 26 distinct configurations, therefore, one strategy control less restrictive than previous. Lastly, we presented one example for highlight the modular characteristic of our methodology, which it is very important to maintenance of applications. In this example, the sensors for identifying pieces in the plant were removed. So, changes in the control model are needed to transmit the information of the input buffer sensor to the others positions of the cell

Group Sequential Communication (GSC): Especificação e Análise de Desempenho de umMecanismo de Comunicação de Tempo Real Compatível ao Padrão IEEE 802.11/11e Aplicado à Automação Industrial

This thesis proposes the specification and performance analysis of a real-time communication mechanism for IEEE 802.11/11e standard. This approach is called Group Sequential Communication (GSC). The GSC has a better performance for dealing with small data packets when compared to the HCCA mechanism by adopting a decentralized medium access control using a publish/subscribe communication scheme. The main objective of the thesis is the HCCA overhead reduction of the Polling, ACK and QoS Null frames exchanged between the Hybrid Coordinator and the polled stations. The GSC eliminates the polling scheme used by HCCA scheduling algorithm by using a Virtual Token Passing procedure among members of the real-time group to whom a high-priority and sequential access to communication medium is granted. In order to improve the reliability of the mechanism proposed into a noisy channel, it is presented an error recovery scheme called second chance algorithm. This scheme is based on block acknowledgment strategy where there is a possibility of retransmitting when missing real-time messages. Thus, the GSC mechanism maintains the real-time traffic across many IEEE 802.11/11e devices, optimized bandwidth usage and minimal delay variation for data packets in the wireless network. For validation purpose of the communication scheme, the GSC and HCCA mechanisms have been implemented in network simulation software developed in C/C++ and their performance results were compared. The experiments show the efficiency of the GSC mechanism, especially in industrial communication scenarios.

Conversor CC/CA de alta freqüência baseado em inversores ressonantes com comutação seqüencial para excitação de uma tocha indutiva a plasma térmico

This work describes the study, the analysis, the project methodology and the constructive details of a high frequency DC/AC resonant series converter using sequential commutation techniques for the excitation of an inductive coupled thermal plasma torch. The aim of this thesis is to show the new modulation technique potentialities and to present a technological option for the high-frequency electronic power converters development. The resonant converter operates at 50 kW output power under a 400 kHz frequency and it is constituted by inverter cells using ultra-fast IGBT devices. In order to minimize the turn-off losses, the inverter cells operates in a ZVS mode referred by a modified PLL loop that maintains this condition stable, despite the load variations. The sequential pulse gating command strategy used it allows to operate the IGBT devices on its maximum power limits using the derating and destressing current scheme, as well as it propitiates a frequency multiplication of the inverters set. The output converter is connected to a series resonant circuit constituted by the applicator ICTP torch, a compensation capacitor and an impedance matching RF transformer. At the final, are presented the experimental results and the many tests achieved in laboratory as form to validate the proposed new technique

Uso de renderização volumétrica e realidade virtual para problemas de percolação na engenharia

In the recovering process of oil, rock heterogeneity has a huge impact on how fluids move in the field, defining how much oil can be recovered. In order to study this variability, percolation theory, which describes phenomena involving geometry and connectivity are the bases, is a very useful model. Result of percolation is tridimensional data and have no physical meaning until visualized in form of images or animations. Although a lot of powerful and sophisticated visualization tools have been developed, they focus on generation of planar 2D images. In order to interpret data as they would be in the real world, virtual reality techniques using stereo images could be used. In this work we propose an interactive and helpful tool, named ZSweepVR, based on virtual reality techniques that allows a better comprehension of volumetric data generated by simulation of dynamic percolation. The developed system has the ability to render images using two different techniques: surface rendering and volume rendering. Surface rendering is accomplished by OpenGL directives and volume rendering is accomplished by the Zsweep direct volume rendering engine. In the case of volumetric rendering, we implemented an algorithm to generate stereo images. We also propose enhancements in the original percolation algorithm in order to get a better performance. We applied our developed tools to a mature field database, obtaining satisfactory results. The use of stereoscopic and volumetric images brought valuable contributions for the interpretation and clustering formation analysis in percolation, what certainly could lead to better decisions about the exploration and recovery process in oil fields

The popularization of the Internet has stimulated the appearance of Search Engines that have as their objective aid the users in the Web information research process. However, it s common for users to make queries and receive results which do not satisfy their initial needs. The Information Retrieval in Context (IRiX) technique allows for the information related to a specific theme to be related to the initial user query, enabling, in this way, better results. This study presents a prototype of a search engine based on contexts built from linguistic gatherings and on relationships defined by the user. The context information can be shared with softwares and other tool users with the objective of promoting a socialization of contexts

Desenvolvimento de um ressoador retangular de fenda com múltiplas camadas de substrato e com utilização de material PBG para sistema de comunicação sem fio

In the globalized world modern telecommunications have assumed key role within the company, causing a large increase in demand for the wireless technology of communication, which has been happening in recent years have greatly increased the number of applications using this technology. Due to this demand, new materials are developed to enable new control mechanisms and propagation of electromagnetic waves. The research to develop new technologies for wireless communication presents a multidisciplinary study that covers from the new geometries for passive antennas, active up to the development of materials for devices that improve the performance at the frequency range of operation. Recently, planar antennas have attracted interest due to their characteristics and advantages when compared with other types of antennas. In the area of mobile communications the need for antennas of this type has become increasingly used, due to intensive development, which needs to operate in multifrequency antennas and broadband. The microstrip antennas have narrow bandwidth due to the dielectric losses generated by irradiation. Another limitation is the degradation of the radiation pattern due to the generation of surface waves in the substrate. Some techniques have been developed to minimize this limitation of bandwidth, such as the study of type materials PBG - Photonic Band Gap, to form the dielectric material. This work has as main objective the development project of a slot resonator with multiple layers and use the type PBG substrate, which carried out the optimization from the numerical analysis and then designed the device initially proposed for the band electromagnetic spectrum between 3-9 GHz, which basically includes the band S to X. Was used as the dielectric material RT/Duroid 5870 and RT/Duroid 6010.LM where both are laminated ceramic-filled PTFE dielectric constants 2.33 and 10.2, respectively. Through an experimental investigation was conducted an analysis of the simulated versus measured by observing the behavior of the radiation characteristics from the height variation of the dielectric multilayer substrates. We also used the LTT method resonators structures rectangular slot with multiple layers of material photonic PBG in order to obtain the resonance frequency and the entire theory involving the electromagnetic parameters of the structure under consideration. xviii The analysis developed in this work was performed using the method LTT - Transverse Transmission Line, in the field of Fourier transform that uses a component propagating in the y direction (transverse to the real direction of propagation z), thus treating the general equations of the fields electric and magnetic and function. The PBG theory is applied to obtain the relative permittivity of the polarizations for the sep photonic composite substrates material. The results are obtained with the commercial software Ansoft HFSS, used for accurate analysis of the electromagnetic behavior of the planar device under study through the Finite Element Method (FEM). Numerical computational results are presented in graphical form in two and three dimensions, playing in the parameters of return loss, frequency of radiation and radiation diagram, radiation efficiency and surface current for the device under study, and have as substrates, photonic materials and had been simulated in an appropriate computational tool. With respect to the planar device design study are presented in the simulated and measured results that show good agreement with measurements made. These results are mainly in the identification of resonance modes and determining the characteristics of the designed device, such as resonant frequency, return loss and radiation pattern

Contribuição para o estudo do embarque de uma rede neural artificial em field programmable gate array (FPGA)

This study shows the implementation and the embedding of an Artificial Neural Network (ANN) in hardware, or in a programmable device, as a field programmable gate array (FPGA). This work allowed the exploration of different implementations, described in VHDL, of multilayer perceptrons ANN. Due to the parallelism inherent to ANNs, there are disadvantages in software implementations due to the sequential nature of the Von Neumann architectures. As an alternative to this problem, there is a hardware implementation that allows to exploit all the parallelism implicit in this model. Currently, there is an increase in use of FPGAs as a platform to implement neural networks in hardware, exploiting the high processing power, low cost, ease of programming and ability to reconfigure the circuit, allowing the network to adapt to different applications. Given this context, the aim is to develop arrays of neural networks in hardware, a flexible architecture, in which it is possible to add or remove neurons, and mainly, modify the network topology, in order to enable a modular network of fixed-point arithmetic in a FPGA. Five synthesis of VHDL descriptions were produced: two for the neuron with one or two entrances, and three different architectures of ANN. The descriptions of the used architectures became very modular, easily allowing the increase or decrease of the number of neurons. As a result, some complete neural networks were implemented in FPGA, in fixed-point arithmetic, with a high-capacity parallel processing

Influência da adição de rejeitos cerâmicos nas propriedades de cerâmica vermelha da região do Recôncavo Baiano

The study of the physical and mechanic properties is an analysis of unquestioned importance on the production of the ceramic materials. In the region of the Recôncavo Baiano, there are ceramic and small brick factories, that still use rudimentary techniques, where the necessity of characterization of raw materials is denounced by the quality of the final product. The present work has for objective to study the behavior of the clay proceeding from the region of the Recôncavo, between the cities of Candeias and Camaçari/Ba, with addition of 5, 10 and 15% by weight of brick scraps, trying to optimize the physic and mechanical properties of the final product, aiming a better possibility of being manufactured, mechanic resistance, low linear retraction and water absorption. The brick scraps and the clay were characterized by FRX, DRX, TG, ATD and the granulometric analysis. Samples for testing where prepared by uniaxial pressing at 25Mpa, in 60x20x5mm size. The evaluated technological properties were: linear retraction, water absorption, apparent porosity and flexural strength. The samples were burned in electric oven in the temperatures of 850º, 950º and 1050ºC and compared its mechanical properties and the gresification. With addition of 15% by weight of brick scraps and burning at 900º-1000ºC the samples showed properties superior to that clay
