    • Sociodemographic Factors Influencing Vietnamese Patient Satisfaction with Healthcare Services and Some Meaningful Empirical Thresholds
    Authors: Quan-Hoang Vuong;  Advisor: -;  Co-Author: - (2018)

    Background: This short communication report some new results obtained from a medical survey among 900 Vietnamese patients in 2015, looking into possibly influential sociodemographic factors as far as patient satisfaction is concerned, to establish empirical relationships between them for policy implications. Methods: The study employed the baseline category logit models to establish empirical relationships between predictor variables and responses, which reflect different levels of satisfaction. Results: Income, medical expenditure, and insurance coverage have the positive influence on improving patient satisfaction. However, insurance reimbursement rate has the negative influence. Patients with residency status are more demanding than those without. The more seriously ill, th...

    Network coding (NC) has been recently emerging as an excellent technique for leveraging network efciency. In optical networks, NC and protection appear to be a good match and indeed, NC could be efectively exploited for greater protection efciency thanks to the opportunity of combining signals rather than duplication in the traditional approach. Motivated by this observation, we investigate the application of a simple and practical NC technique based on XOR operation to improve the network throughput in survivable optical networks. To this end, we propose the NC-based protection whose speed recovery is on a par with the conventional 1 + 1 dedicated protection while the capacity usage could be more efcient, paving the way for improving throughput in constrained capacity conditions.
