Design de interfaces para aplicativo de smartphone como recurso auxiliar no acompanhamento clínico de pacientes fibromiálgicos

Este trabalho tem como objetivo o desenvolvimento de interfaces com o usuário para aplicativo móvel smartphones com intuito de contribuir para a eficiência das atividades de profissionais e pesquisadores da área de fisioterapia ao oferecer suporte ao acompanhamento clínico da dor no tratamento de pacientes fibromiálgicos. Utilizando a abordagem de Design Centrado no Usuário - DCU, foram realizadas entrevistas e uma investigação contextual para a identificação inicial dos problemas e necessidades dos usuários. Verificou-se que as atividades de monitoramento e acompanhamento das sessões do tratamento de pacientes fibromiálgicos são, tradicionalmente, realizadas por meio de manipulando de formulários e fichas em papel (registro das condições de saúde do paciente) e escalas de classificação da dor em formato impresso (apresentadas ao paciente para indicação de sua dor percebida para cada ponto pré-determinado do corpo). Os procedimentos envolvidos nestas atividades dificultam o gerenciamento do desempenho do tratamento, o que, segundo relatos, reflete no comprometimento dos pacientes na adesão e frequência as sessões. A partir da observação e do levantamento das necessidades desses profissionais diante de suas atividades, foi proposto um aplicativo para smartphone com a intenção de minimizar os problemas ocasionados pelo uso das ferramentas convencionais e de prover informações rápidas acerca dos dados coletados. Então, seguindo a abordagem do DCU foi elaborado um modelo conceitual durante a etapa de concepção de soluções, o qual guiou a criação dos protótipos. A avaliação das interfaces do protótipo foi realizada com o envolvimento dos usuários a partir da técnica de avaliação cooperativa. Seus resultados proporcionaram o refinamento das interfaces e o desenvolvimento de uma nova proposta do design das interfaces em protótipo de alta fidelidade, produzido para o ambiente Android. Assim, esse trabalho faz parte do processo de desenvolvimento de um produto de software personalizado com foco na concepção e avaliação das interfaces com o usuário. Por meio da metodologia aplicada, observaram-se indícios os quais sugerem que as interfaces propostas apresentaram-se como um recurso facilitador e capaz de contribuir para eficiência das atividades no acompanhamento do tratamento de pacientes fibromiálgicos

A experiência do usuário idoso no design de jogo digital para a reabilitação neural de pacientes com quadro de acidente vascular cerebral (AVC)

Stroke is nowadays one of the main causes of death in Brazil and worldwide. During the rehabilitation process, patients undergo physioterapic exercises based on repetition, which may cause them to feel little progress is being made. Focusing on themes from the areas of Human-Computer Interaction and Motor Imagery, the present work describes the development of a digital game concept aimed at motor rehabilitation to the neural rehabilitation of patients who have suffered a stroke in a playful and engaging way. The research hypothesizes that an interactive digital game based on Motor Imagery contributes to patients' raised commitment in the stroke sequel rehabilitation process. The research process entailed the investigation of 10 subjects who live with sequels caused by stroke - it was further established that subjects were over 60 years old. Using as foundation an initial survey regarding target-users' specificities, where an investigation on subjectrelated aspects was carried out through Focus Group (n=9) and Contextual Analysis (n=3), having as subjects elderly individuals, a list with the necessary requirements for the conceptualization of a digital game was fleshed out. The initial survey also enabled the establishment of preliminary interactions for the formulation of game prototypes. At first, low-resolution prototypes were used, with two distinct interaction models for the game - one with a direct approach to the Motor Imagery concept, and another using a narrative with characters and scene settings. The goal was to verify participants' receptivity regarding the addition of playful activities into game dynamics. Prototypes were analyzed while being used by five patients, through the Cooperative Evaluation technique. The tests indicated a preference for option with elements in a playful narrative. Based on these results high fidelity prototypes were created, where concepts close to the game's final version were elaborated. The High Fidelity prototype was also evaluated with four patients through the Cooperative Evaluation technique. It was concluded that elderly individuals and patients were receptive to the idea of a digital game for the rehabilitation from sequels caused by stroke; that, for the success of devices aimed at these cohorts, their contexts, needs and expectations must be respected above all; and that user-centered design is an essential approach in that regard.

Sistema especialista fuzzy para dimensionamento de bombeio mecânico

Despite the emergence of other forms of artificial lift, sucker rod pumping systems remains hegemonic because of its flexibility of operation and lower investment cost compared to other lifting techniques developed. A successful rod pumping sizing necessarily passes through the supply of estimated flow and the controlled wear of pumping equipment used in the mounted configuration. However, the mediation of these elements is particularly challenging, especially for most designers dealing with this work, which still lack the experience needed to get good projects pumping in time. Even with the existence of various computer applications on the market in order to facilitate this task, they must face a grueling process of trial and error until you get the most appropriate combination of equipment for installation in the well. This thesis proposes the creation of an expert system in the design of sucker rod pumping systems. Its mission is to guide a petroleum engineer in the task of selecting a range of equipment appropriate to the context provided by the characteristics of the oil that will be raised to the surface. Features such as the level of gas separation, presence of corrosive elements, possibility of production of sand and waxing are taken into account in selecting the pumping unit, sucker-rod strings and subsurface pump and their operation mode. It is able to approximate the inferente process in the way of human reasoning, which leads to results closer to those obtained by a specialist. For this, their production rules were based on the theory of fuzzy sets, able to model vague concepts typically present in human reasoning. The calculations of operating parameters of the pumping system are made by the API RP 11L method. Based on information input, the system is able to return to the user a set of pumping configurations that meet a given design flow, but without subjecting the selected equipment to an effort beyond that which can bear

Projeto e controle de um sistema de aquecimento no Laboratório de Avaliação de Medição em Petróleo

The Oil Measurement Evaluation Laboratory (LAMP), located in the Federal University of Rio Grande do Norte (UFRN), has as main goal to evaluate flow and BS&W meters, where the simulation of a bigger number of operation variable in field, guarantees a less uncertain evaluation. The objective of this work is to purpose a heating system design and implementation, which will control the temperature safely and efficiently in order to evaluate and measure it. Temperature is one of the variables which influence the flow and BS&W accurate measurement, directly affecting the fluid viscosity and density in the experiment. To project the heating system it is of great importance to take the laboratory requirements, conditions and current restrictions into consideration. Three alternatives were evaluated: heat exchanger, internal resistance and external resistance. After the analyses are made in order to choose the best alternative for the heating system in the laboratory, control strategies were determined for it, PID control methods in combination with fuzzy logic were used. Results showed a better performance with fuzzy logic than with classic PID
