An edge wave numerical model was developed based on extended Boussinesq equations with the internal wave-generation method. The form of edge waves near a seawall was chosen as the input signal in order to avoid treatment of the moving shoreline on a sloping beach. As there was an energy transfer between different edge wave modes, not only the target mode but also other modes appeared in the simulations. Due to the nonlinear effect, the simulation results for mode-0 edge waves were slightly modulated by mode-1 and mode-2 waves. As the magnitudes of these higher-mode waves are not significantly related to those of the target mode, the internal wave-generation method in Boussinesq equations can produce high-quality edge waves. The numerical model was used to investigate the nonlinear properties of standing edge waves, and the numerical results were in strong agreement with theory. 展开更多

The aim of the present study was to measure the prevalence of multimorbidity in Bangladesh,India and China,and to assess the relationship between multimorbidity and patient's opinion regarding their involvement in healthcare decision-making and overall satisfaction of healthcare system.Cross-sectional data on 18696 men and women aged 18 and above were collected from the World Health Survey of World Health Organization(WHO).Outcome variables were subjective rating of(1)healthcare system's ability to involve patients in decision-making,and(2)satisfaction with the way healthcare system runs in the country.Self-reported chronic conditions were used to measure the prevalence of multimorbidity.Out of 9 chronic conditions,back pain,arthritis,and chronic cough appeared to be the most prevalent ones among majority of the participants.About one-third of the participants in China(30.7%)and two-thirds in Bangladesh(66.1%)and India(66.6%)reported having at least one chronic illness.Prevalence of multimorbidity was highest in India(34.3%)followed by Bangladesh(28.8%)and China(14.3%).In Bangladesh,India and China,respectively 70.5%,41.7%,61.3%women and 54.5%,42.8%and 58.8%men expressed dissatisfaction regarding the way healthcare system runs in their country.In Bangladesh and India,men who were living with multimorbidity were more likely to rate the patient-centeredness as"bad"than those who had no disease illness.This study suggests that the prevalence of multimorbidity was remarkably high especially in Bangladesh and India.Higher likelihood of dissatisfaction about healthcare system among multimorbid patients might be indicative of inadequacy in the provision of care in qualitative and quantitative terms. 展开更多
