Teachers often use videos to teach their students, but stories are not used as often in educational videos as they could be. Experts tell us that stories are an important part of teaching and learning. Unfortunately, there is only a small amount of research and no definitive expert agreement about stories used in educational videos. This is especially true for videos used with technical education students, like mechanic students or dental assisting students. In this study, dental assisting students learned how to assist a dentist with a standard cavity procedure after watching a video with or without a story. The study measured which video helped students get better quiz scores, feel more motivated, and which videos they preferred better. The students were randomly assigned to watch either video. The results demonstrated no significant difference in quiz scores or motivation, part of this was due to the low number of participants in this section of the study. Another group of students were shown both videos and then interviewed to determine additional insights. Overall, students preferred the video without the story as a reference for the dental cavity procedure. Students also seemed to like the video without the story because it was short and simple. In contrast, students reported the video with the story was more emotionally engaging, especially in regards to developing empathy for patients. Students also reported the video with the story better helped prepared them to work with patients.

A power assisted wheelchair combines human power, which is delivered by the arms through the pushrims, with electrical motors, which are powered by a battery. Today’s electric power assisted wheelchairs use force sensors to measure the torque exerted on the pushrims by the user. The force sensors in the pushrims are rather expensive and this approach also makes the wheels a little bit clumsy. The objective with this project is to find a new, better and cheaper solution that does not use expensive force sensors in the pushrims. The new power assisted wheelchair will instead only rely on its velocity, which is measured with rotational encoders, as feedback signal and thereby the project name “Torque Sensor Free Power Assisted Wheelchair”. The project consisted of two main parts; an extensive construction part, where an ordinary joystick controlled motorized wheelchair has been rebuild to the new power assisted wheelchair without torque sensors and a development part, where different torque sensor free controllers has been designed, simulated, programmed and tested. The project resulted in a torque sensor free power assisted wheelchair, where the final implemented design is a proportional derivative controller, which gives a very good assisting system that is robust and insensitive to measurement noise. The proportional derivative control design gives two adjustable parameters, which can be tuned to fit a certain user; one parameter is used to adjust the amplification of the user’s force and the other one is used to change the lasting time of the propulsion influence. Since the new assisting control system only relies on the velocity, the torque sensor free power assisted wheelchair will besides giving the user assisting power also give an assistant, which pushes the wheelchair, additional power. This is a big advantage compared to the pushrim activated one, where this benefit for the assistant is not possible.

A growing number of factors, including the costs, technological advancements, an ageing population, and medical errors are leading industrialised countries to invest in research on alternative solutions to improving their health care systems and increasing patients’ life quality. Personal Health System (PHS) solutions envision the use of information and communication technologies that enable a paradigm shift from the traditional hospital-centred healthcare delivery model toward a preventive and person-centred approach. PHS offers the means to follow patient health using wearable, portable or implantable systems that offer ubiquitous, unobtrusive bio-data acquisition, allowing remote access to patient status and treatment monitoring.Electrical Bioimpedance (EBI) technology is a non-invasive, quick and relatively affordable technique that can be used for assessing and monitoring different health conditions, e.g., body composition assessments for nutrition. EBI technology combined with state-of-the-art advances in sensor and textile technology are fostering the implementation of wearable bioimpedance monitors that use functional garments for the implementation of personalised healthcare applications.This research studies the development of a portable EBI spectrometer that can use dry textile electrodes for the assessment of body composition for the purposes of clinical uses. The portable bioimpedance monitor has been developed using the latest advances in system-on-chip technology for bioimpedance spectroscopy instrumentation. The obtained portable spectrometer has been validated against commercial spectrometer that performs total body composition assessment using functional textrode garments.The development of a portable Bioimpedance spectrometer using functional garments and dry textile electrodes for body composition assessment has been shown to be a feasible option. The availability of such measurement systems bring closer the real implementation of personalised healthcare systems. / 2013-04-29 Licentiatseminarium kl.10-11.30 The presentation will be broadcast using Adobe Connect.

A manipulação de materiais é uma das tarefas em que comumente empregam-se robôs para substituir o trabalho humano, dadas algumas vantagens como: maior precisão na manipulação de cargas e maior velocidade de execução da tarefa, bem como por aumentar a segurança do operador. Apesar dessas vantagens, os dispositivos robóticos são largamente empregados apenas em situações em que velocidade e precisão são indispensáveis, em outros casos, os equipamentos convencionais (como talhas, gruas e macacos hidráulicos) e os dispositivos específicos (aqueles fazem uso de molas e contrapesos), vêm sendo utilizados nas tarefas cotidianas, principalmente pelo fato de, entre outros, serem menos dispendiosos. Comparando-se estas duas soluções disponíveis, tem-se que os equipamentos tradicionais, apesar de sua simplicidade e versatilidade de movimentação, apresentam limitações quando são exigidas precisão e eficiência, enquanto os dispositivos robóticos apresentam alta complexidade tanto no projeto quanto na operação, representando uma solução cara e com movimentação restrita pela programação. Neste contexto, o presente trabalho tem por objetivo estudar e propor uma solução intermediária entre a solução convencional e a robótica. O foco do estudo é o projeto de um dispositivo simplificado, que faz uso de molas e de um sistema de alavanca para manipular cargas. Um estudo preliminar desse mecanismo mostrou imperfeições quanto à força de contrabalanceamento. Com o intuito de corrigir esse erro foi usado um sistema de controle, que é constituído por um motor elétrico, um mecanismo de correção, sensores e um módulo controlador. O dispositivo proposto apresenta um controle simplificado, vez que a movimentação é feita exclusivamente pelo operador, possibilitando assim que o dispositivo apresente um baixo consumo de energia. Um protótipo é desenvolvido e os testes demonstraram a eficácia da solução. / The material handling is one task in which robot is commonly employed to replace the human work because it has some advantages such as, higher precision in the handling and higher speed of the task, and to increase operator safety. Despite these advantages, the robotic device is most employed only in situation that speed and precision are essential; in other cases, the conventional equipments (such as hydraulic jacks, cranes and pulley systems) and the specific device (which use springs and counterweight), have been used in daily tasks mainly because of they are less expensive. Comparing these two solutions, it is possible to say that the conventional devices, despite its simplicity and guidance, have limitations when the task requires precision and speed, while the robotic solution has higher complexity in both design and in operation, representing an expensive solution with a programming that restrict the movement. In this context, the present work has the objective the study and development of an intermediate solution between the conventional solution and the robotic device. The proposed study is based on a simplified device, which uses springs and a lever system to handle material. A preliminary study on this mechanism shows imperfections in balance force. In order to correct this error, a control system is used. The control system is constituted by an electric motor, a correcting mechanism, sensors and a controller. The proposed device presents simple control because movements are responsibility of the human operator moreover presents low power consumption, due to the use of springs. A prototype is developed and tests demonstrate the effectiveness of the solution.

Os objetivos são: analisar e discutir as tecnologias da informação e comunicação, especialmente a televisão, na educação dos Surdos; estudar alguns posicionamentos e reflexões dos surdos em relação à recepção das informações mediadas pela televisão. Ressalta os aspectos de uma pesquisa de cunho qualitativo que investiga a Educação Especial, Educação dos Surdos, tecnologia, televisão, a imagem, a legenda e a necessidade de agregar todos os programas televisivos à Língua Brasileira de Sinais - Libras. A dissertação apresenta questões específicas sobre a História da Educação dos Surdos, tecnologias assistivas e a contextualização dessas formas de educação no município de Ipiaú. Destaca os pontos de vista dos jovens entrevistados, além dos posicionamentos dos autores selecionados e que fundamentam teoricamente o estudo. A relação dos adolescentes e jovens entrevistados com as tecnologias e as transformações que os mesmos promovem no corpo, na maneira de ser e agir, o principal ponto discutido. A pesquisa constata que, sem o uso da Libras, é grande a dificuldade de um grupo - formado por 15 alunos do Ensino Fundamental e um do Ensino Médio que freqüentam a Sala de Apoio Pedagógico, no município de Ipiaú-BA - ter acesso à informação televisiva, mesmo que esse meio de comunicação encante e fascine todos e seja apontado como principal fonte de informação do que acontece no mundo, no país e ao seu redor. / Salvador

In the State of Sergipe, the modernization processes were always accompanied of several outlines of local development, implementing rural programs that they manifested a mixture productivity and assisting, counting with the loans with BIRD - I Support World and administered by PRONESE - Company of Maintainable Development of State of Sergipe, along the years. That pattern of local or community development direct to the called small rural producers, management in a centralized way, seems to culminate today in a crisis of alarming proportions. It persists the extreme poverty in the rural way, the hunger, the unemployment, the inequality, the aggressions to the environment, the social exclusion, with loss of cultural identity. This study has for objective to analyze the process of the changes in the Economic, Social dimensions and you Set, in the municipal district of Porto of the Leaf, current of the recruiting and operacionalization of the productive, social subprojetos and of infrastructure, originating from of the Program of Reduction of the Rural Poverty - PRPR, administered by PRONESE. Based on the theoretical presuppositions, this study it based in the paradigm phenomenon and he had a focus in the perception and apprehension of the reality built through the social ´´ actors´ perspective involved in the process of the Program of Reduction of the Rural Poverty - PRPR of the municipal district of Porto of the Leaf. Thirty and an interviews were accomplished with the Presidents of Community Associations, in several towns of the municipal district. Amongst the results can stand out besides the white public´s disinformation with relationship to the procedures for acquisition of financings close to PRONESE, the absence of effective attendance to the Associations and the Council, in face of the extinction of the Agents of Change and of the Municipal Fund of Community Support - Fumac-p, as well as the moroseness in the tramitação process and approval of requested Subprojetos, getting to delay in some cases, up to 10 years. Through the analysis of the indicators of this study, it was observed that the Economic, Social actings and you Set current of the program, in the municipal district of Porto da Folha, non did´not get a favorable evaluation and, besides, the articulation process between the Associations and Council with the Power local Public and with PRONESE, it doesn´t come being worked in an effective way, in the promotion of the local maintainable development. / No Estado de Sergipe, os processos de modernização sempre estiveram acompanhados de diversos esquemas de desenvolvimento local, implementando programas rurais que manifestaram uma mistura produtivista e assistencialista, contando com os empréstimos firmados com o BIRD - Banco Mundial e administrados pela PRONESE - Empresa de Desenvolvimento Sustentável do Estado de Sergipe, ao longo dos anos. Esse padrão de desenvolvimento local ou comunitário dirigido aos chamados pequenos produtores rurais, gerenciado de forma centralizada, parece culminar hoje numa crise de proporções alarmantes. Persiste a pobreza extrema no meio rural, a fome, o desemprego, a desigualdade, as agressões ao meio ambiente, a exclusão social, com perda de identidade cultural. Este estudo tem por objetivo analisar o processo das mudanças nas dimensões Econômicas, Sociais e Ambientais, no município de Porto da Folha, decorrentes da contratação e operacionalização dos subprojetos produtivos, sociais e de infra-estrutura, oriundos do Programa de Redução da Pobreza Rural - PRPR, administrado pela PRONESE. Baseado nos pressupostos teóricos, este estudo se fundamentou no paradigma fenomenológico e teve um enfoque na percepção e apreensão da realidade construída através da perspectiva dos ´atores sociais´ envolvidos no processo do Programa de Redução da Pobreza Rural - PRPR do município de Porto da Folha. Foram realizadas trinta e uma entrevistas com os Presidentes de Associações Comunitárias, em diversos povoados do município. Dentre os resultados pode-se destacar além da desinformação do público alvo quanto aos procedimentos para aquisição de financiamentos junto a PRONESE, a ausência de assistência efetiva às Associações e ao Conselho, em face da extinção dos Agentes de Mudança e do Fundo Municipal de Apoio Comunitário - Fumac-p, bem como a morosidade no processo de tramitação e aprovação dos Subprojetos solicitados, chegando a demorar em alguns casos, até 10 anos. Através da análise dos indicadores deste estudo, observou-se que os desempenhos Econômicos, Sociais e Ambientais decorrentes do programa, no município de Porto da Folha, não auferiu uma avaliação favorável e, além disso, o processo de articulação entre as Associações e Conselho com o Poder Público local e com a PRONESE, não vem sendo trabalhado de forma efetiva, na promoção do desenvolvimento sustentável local.

This is a study about English teachers’ perception on teaching students with dyslexia reading and reading strategies and their knowledge gained on the subject matter. The aim was to identify, describe and analyse the teacher‟s perceptions of teaching Swedish students with dyslexia in four Swedish mainstream secondary schools. The data for this study was collected by interviews from four English teachers in four different mainstream secondary schools. The results show that English teachers get too little in-service training from their employer about dyslexia and reading difficulties. In addition the English teachers need to become more familiar with what reading strategies are and what new learning assisting materials students with dyslexia can make use of, such as new applications and the new HELP-program.
