Utilizando tecnologia móvel oferecemos um curso de atualização sobre medida indireta da pressão arterial para profissionais de enfermagem de três Unidades Básicas de Saúde do Distrito Oeste do município de Ribeirão Preto. Estudo descritivo exploratório que contou com a participação de 11 auxiliares de enfermagem. Avaliamos estes profissionais em quatro fases distintas: avaliação diagnóstica, processual, somativa e de uso da tecnologia móvel e avaliação teórico-prática. Os resultados indicam lacunas no conhecimento relativo a alguns aspectos que envolvem a medida indireta da pressão arterial, quando da avaliação das atividades pedagógicas na fase processual. A maioria dos profissionais obteve bom desempenho na realização do procedimento após o curso. Todos 11 (100,0%) avaliaram positivamente o uso do dispositivo móvel (Tablet) na educação permanente em serviço, indicando que gostariam de participar de outras experiências com o uso do recurso. Concluímos que o presente estudo apresenta limitações decorrentes do reduzido numero de participantes, além de imposições estabelecidas pelo serviço, quanto à guarda dos equipamentos. Neste sentido recomendamos a realização de novos estudos com vistas a dimensionar melhor os aspectos aqui identificados. / An updating course on indirect blood pressure measurement, using mobile technology, was offered to nursing professionals from three Basic Health Units of the Western District of the city of Ribeirão Preto. This exploratory and descriptive study had the participation of 11 nursing auxiliaries. These professionals were evaluated in four different phases: diagnostic, processual and summative assessments and use of mobile technology and theory and practice evaluation. Results indicate gaps in knowledge related to aspects that involve indirect blood pressure measurement, when evaluating the educational activities in the processual phase. Most professionals had a good performance on accomplishing the procedure after the course. All 11 (100.0%) positively evaluated the use of the mobile device (Tablet) in continuing education at service, indicating they would like to participate in other activities using the resource. It was concluded that this study has limitations due to the small number of participants and the rules established by the service as to the custody of equipments. Thus, further studies should be proposed in order to better scale the aspects identified by this study.

A key step in the handover process corresponds to the decision phase in which the mobile device selects the candidate network that it will be attached to. The criterion generally used in the decision step is the signal strength of the available network. In addition to the signal power, other criteria also need to be explored in heterogeneous environments for taking handover decision, since the network technologies differ in the types of services, protocols, quality standards, frequency bands and monetary costs. This paper proposes a handover decision algorithm based on cost function that takes into account both the received signal power, some quality of service criteria such as packet loss rate, delay and jitter, as well as the energy consumption of network interface of the mobile station. In order to evaluate the performance of the algorithm were considered two scenarios, one in which the battery of device mobile is sufficiently charged and another where it meets the low load. Simulations in NS-2 were performed in an environment compound by the Wi-Fi and WiMAX networks. The results showed that the proposed algorithm helped to reduce the number of wrong handovers decisions, so that there was no deterioration in the quality of service that would affect the performance of the network in which the mobile device is currently connected. / Uma etapa fundamental no processo de handover corresponde à fase de decisão, na qual é selecionada a rede candidata para a qual o dispositivo móvel irá se transferir. O critério normalmente utilizado na etapa de decisão é a potência de sinal da rede que se encontra disponível. Além da potência de sinal, outros critérios também necessitam ser explorados em ambientes heterogêneos para a tomada de decisão de handover, uma vez que as tecnologias de rede divergem quanto aos tipos de serviços, protocolos, níveis de qualidade, faixas de frequência e custos monetários. Este trabalho propõe um algoritmo de decisão de handover baseado em função de custo que leva em consideração, além da potência de sinal recebida, alguns critérios de Qualidade de Serviço, tais como taxa de perda de pacotes, atraso e jitter, bem como o consumo de energia da interface de rede da estação móvel. A fim de avaliar o desempenho do algoritmo foram considerados dois cenários, um no qual a bateria do terminal móvel está com carga suficiente e outro onde a mesma se encontra com a carga baixa, sendo realizadas simulações no NS-2 em um ambiente composto pelas redes Wi-Fi e WiMAX. Os resultados obtidos mostraram que o algoritmo proposto contribuiu para reduzir o número de decisões erradas de handovers, de modo que não houvesse uma degradação da Qualidade de Serviço que viesse a afetar o desempenho da rede na qual o terminal móvel se encontra conectado.

Using a modified still-face procedure the present study explores 3-6-month-old infants' behavioral and physiological responses to mothers' screen distractions during mother-infant interactions. In the modified phone still-face procedure the neutral face of the traditional still face procedure was replaced with mothers' texting on their mobile phones. Infants' cortisol stress responses to mothers' device use were assessed through the collection of 3 infant saliva samples. Infants' behavioral responses including facial expressions, vocalizations, gaze and self-comforting behaviors were also explored. All mother-infant interactions were videoed recorded and coded for analysis. Thirty-four mother-infant dyads participated, average ages for mothers was 29 years and 4.4 months for infants. As predicted, infants demonstrated the changes in affect associated with the still-face effect, with significant differences in positive and negative affect during the play phases and the phone still face phase. As a whole, infants did not respond with increased cortisol responses, however, when individual differences were explored 47% responded with increased stress during mothers' phone distractions. Mother's frequency and attitudes towards device use were also assessed but were unrelated to infant responses. Implications and directions for future research are discussed.
