    Abstract Abstract The excitation technology for high-g-level shock environment experiments is currently a topic of interest, for which velocity amplification by collisions of vertically stacked bodies has been used to develop high-g shock tests with great success. This study investigated the superelastic collision effects generated during high-velocity one-dimensional three-body impacts. Theoretical formulae were derived in brief for an analytical investigation of the collisions. Four experiments were performed with different initial velocities obtained from free-falls from different heights. Velocity gains larger than 5 were obtained for the three-body collisions, and coefficients of restitution larger than 2.5 were observed for the second impact. The experimental results well verified the existence of superelastic collision effects in the one-dimensional three-body impacts.

    Abstract Abstract Background Currently, population aging has been an obstacle and the spotlight for all countries. Compared with developed countries, problems caused by China’s aging population are more prominent. Beijing, as a typical example, is characterized by advanced age and high disability rate, making this capital city scramble to take control of this severe problem. The main types of care for the disabled elderly are classified as home care, institutional care, and community care. With the obvious shortage of senior care institutions, most disabled elderly people are prone to choose home care. This kind of elderly care model is in line with the traditional Chinese concept and it can save the social cost of the disabled elderly to the greatest extent. However, home care for the disabled elderly is facing bumps from the whole society, such as lack of professional medical care, social support and humanistic care, and the care resources provided by a single subject cannot meet the needs of the disabled elderly. Objective Based on the demands of the disabled elderly and their families, this study aims to explore the current status of home care service, look for what kind of care is more suitable for the disabled elderly, and try to find an appropriate elderly care mechanism which could meet the diverse needs of the disabled elderly. Methods A total of 118 disabled elderly people and their primary caregivers were selected from four districts of Beijing by using multi-stage stratified proportional sampling method. A one-to-one and semi-structured in-depth qualitative interview were conducted in the study to find out the health status of the disabled elderly, the relationship between the disabled elderly and their primary caregivers, and utilization of elderly care resources, etc. The views of the interviewees were analyzed through the thematic framework method. All the methods were carried out in accordance with relevant guidelines and regulations. Results The results showed that the average age of 118 disabled elderly ...

    Abstract Objective To evaluate the current state of family doctor contract services (FDCS) in Beijing, identify the roles of family doctors who have worked with disabled older adults and investigate the barriers and facilitators faced by family doctors in providing care for them.Design A convergent mixed methods study was carried out from October 2020 to January 2021 to collect and analyse both quantitative and qualitative data. The integration strategies in this study were connecting the results of the quantitative phase to data collection of the qualitative phase.Setting A multi-stage sampling strategy was used to select 15 community health centres (CHCs) in four districts of Beijing. Of the four districts, two were from urban areas and two were from rural areas.Participants The inclusion criteria for participants were (1) family doctors, (2) contracted with disabled older adults, (3) engaged in related work for disabled older adults more than 6 months.Methods A cluster sampling of 283 family doctors was used in the questionnaire. A purposive sample of 30 family doctors from the same CHCs was selected during the same period. Frequency and rank, rank-sum test, Kruskal-Wallis test were conducted in qualitative data analysis, the views of the interviewees were analysed through the thematic framework method.Results Currently, family doctors provided various services to satisfy the health needs of disabled older adults, while the usage of FDCS for disabled older adults is affected by many factors. The differences of the importance of family doctors’ role (p<0.001) and service satisfaction (p=0.004) were significant among four districts. Compared with contracted health senior citizens, this study has identified five unique roles of family doctors, including ‘psychological consultant’, ‘rehabilitation physiotherapist’, ‘health educator’, ‘health manager’ and ‘family health guardian’. Moreover, family doctors are confronted with a myriad of barriers (including high risks in the process of home visits, a lack of supervisory ...

    Abstract Objective: To evaluate the degree to which electronic medical records (EMRs) were used in primary care and the value of EMRs as perceived by primary care workers in China. Methods: A cross-sectional survey was conducted on 2719 physicians ( n = 2213) and nurses ( n = 506) selected from 462 community health centres across all regions of mainland China except for Tibet. Regional differences in the responses regarding the functionality of existing EMR systems and the perceived value of EMRs were examined using Chi-square tests and ordinal regression analyses. Results: Less than 59% of the community health centres had adopted EMRs. More than 89% of the respondents believed that it was necessary to adopt EMRs in primary care. Of the existing EMR systems, 50% had access to telehealth support for laboratory, imaging or patient consultation services. Only 38.4% captured data that met all task needs and 35.4% supported referral arrangements. “Management of chronic conditions” was voted (66%) as the top preferred feature of EMRs. Higher levels of recognition of the value of EMRs were found in the relatively more developed eastern region compared with their counterparts in other regions. Conclusions: Rapid EMR adoption in primary care is evident in mainland China. The low level of functionality in data acquisition and referral arrangements runs counter to the requirements for “management of chronic conditions”, the most preferred feature of EMRs in primary care. Regional disparities in the realised value of EMRs in primary care deserve policy attention.
