Abstract: In silicon-oxide-nitride-oxide-silicon (SONOS) memory and other charge trapping memories,the charge distribution after programming operation has great impact on the device’s characteristics,such as reading,programming/erasing,and reliability.The lateral distribution of injected charges can be measured precisely using the charge pumping method.To improve the precision of the actual measurement,a combination of a constant low voltage method and a constant high voltage method is introduced during the charge pumping testing of the drain side and the source side,respectively.Finally,the electron distribution after channel hot electron programming in SONOS memory is obtained,which is close to the drain side with a width of about 50nm.

Abstract: Today, wide-open, high-resolution Doppler frequency shift (DFS) estimation is essential for radar, microwave/millimeter-wave, and communication systems. Using photonics technology, an effective approach is proposed and experimentally demonstrated, providing a high-resolution and frequency-independent solution. In the approach consisting of two cascaded opto-electronic modulators, DFS between the transmitted microwave/ millimeter-wave signal and the received echo signal is mapped into a doubled spacing between two target optical sidebands. Subsequently, the DFS is then estimated through the spectrum analysis of a generated low-frequency electrical signal, with an improved resolution by a factor of 2. In experiments, DFSs from -90 to 90 KHz are successfully estimated for microwave/millimeter-wave signals at 10, 15, and 30 GHz, where estimation errors keep lower than +/- 5e-10 Hz. For radial velocity measurement, these results reveal a range from 0 to 900 m/s (0 to 450 m/s) and a resolution of 1e-11 m/s (5e-12 m/s) at 15-GHz (30-GHz) frequency band.

Abstract: This study collaborated with the National Bureau of Statistics to collect a sample of 3,424 residents from 17 provinces and municipalities in a 2008 China household survey on patient's trust in medical service, patient's attitude towards health policy, patient's overall satisfaction and sub satisfaction in current medical experience.Patient's overall satisfaction with medical service and most kinds of sub satisfaction in current medical experience were significantly influenced by both patient's trust in medical service and patient's attitude towards health policy; among all kinds of sub satisfaction in current medical experience, patient's trust in medical service/patient's attitude towards health policy had the largest influence on patient's satisfaction with medical costs, the influences of patient's trust in medical service/patient's attitude towards health policy on patient's satisfaction with doctor-patient interaction and satisfaction with treatment process were at medium-level, patient's trust in medical service/patient's attitude towards health policy had the smallest influence on patient's satisfaction with medical facilities and hospital environment, while patient's satisfaction with waiting time in hospital was not influenced by patient's trust in medical service/patient's attitude towards health policy.In order to improve patient's overall satisfaction with medical service and sub satisfaction in considering patient's trust in medical service and patient's attitude towards health policy, both improving patient's interpersonal trust in medical service from individual's own medical experience/public trust in medical service and improving patient's attitude towards health policy were indirect but effective ways.Over the past few decades, patient satisfaction has taken a prominent position in the medical service research literature [1-3]. This attention has been justified since patient satisfaction (directly or indirectly) has become a key criterion for eval

Abstract: Background Although the Chinese government put a lot of effort into promoting the community patient’s life satisfaction, there still lacked the holistic and systematic approaches to promote the community patient’s life satisfaction in various regions of China. On the basis of the literature, it was found that both the community patient’s assessment of community medical service and trust in community health delivery system were important considerations when the community patient comprehensively evaluated community medical service to generate life satisfaction. So this study was set up to test whether and to what extent the community patient’s assessments of various major aspects of community medical service/various major aspects of the community patient’s trust in community health delivery system influenced life satisfaction in whole China/in various regions of China. Methods In order to explore the situation of China’s community health delivery system before 2009 and provide a reference for China’s community health delivery system reform, the data that could comprehensively and accurately reflect the community patient’s life satisfaction, assessment of community medical service, and trust in community health delivery system in various regions of China was needed, so this study collaborated with the National Bureau of Statistics of China to carry out a large-scale 2008 national community resident household survey (N = 3,306) for the first time in China. And the specified ordered probit models were established to analyze the dataset from this household survey. Results Among major aspects of community medical service, the medical cost (particularly in developed regions), the doctor-patient communication (particularly in developed regions), the medical facility and hospital environment (particularly in developed regions), and the medical treatment process (particularly in underdeveloped regions) were all key considerations (p<0.05 for t statistics) in generating the community patient’s life satisfaction. Among major aspects of the community patient’s trust in community health delivery system, trust in doctor (particularly in underdeveloped regions), trust in prescription (particularly in underdeveloped regions), and trust in recommended medical examination (particularly in underdeveloped regions) were all important considerations (p<0.10 for t statistics) in generating the community patient’s life satisfaction. Conclusion The reduction of medical cost (particularly in developed regions), the improvement of doctor-patient communication (particularly

Abstract: Background Patient’s satisfaction with medical service delivery/assessment of medical service/trust in health delivery system may have significant influence on patient’s life satisfaction in China’s health delivery system/in various kinds of hospitals. The aim of this study was to test whether and to what extent patient’s satisfaction with medical service delivery/patient’s assessments of various major aspects of medical service/various major aspects of patient’s trust in health delivery system influenced patient’s life satisfaction in China’s health delivery system/in various kinds of hospitals. Methods This study collaborated with National Bureau of Statistics of China to carry out a 2008 national urban resident household survey in 17 provinces, autonomous regions, and municipalities directly under the central government (N = 3,386), and specified ordered probit models were established to analyze dataset from this household survey. Results The key considerations in generating patient’s life satisfaction involved patient’s overall satisfaction with medical service delivery, assessment of doctor-patient communication, assessment of medical cost, assessment of medical treatment process, assessment of medical facility and hospital environment, assessment of waiting time for medical service, trust in prescription, trust in doctor, and trust in recommended medical examination. But the major considerations in generating patient’s life satisfaction were different among low level public hospital, high level public hospital, and private hospital. Conclusion The promotion of patient’s overall satisfaction with medical service delivery, the improvement of doctor-patient communication, the reduction of medical cost, the improvement of medical treatment process, the promotion of medical facility and hospital environment, the reduction of waiting time for medical service, the promotion of patient’s trust in prescription, the promotion of patient’s trust in doctor, and the promotion of patient’s trust in recommended medical examination could all help promote patient’s life satisfaction. But their promotion effects were different among low level public hospital, high level public hospital, and private hospital.

Abstract: Background The promotion of patient safety and drug safety through promotion of pharmacist’s drug safety practice was among the most important aims of China’s health delivery system reform, but regional inequity in pharmacist’s drug safety practice was still serious in China. Methods The 2011 national patient safety and medication error baseline survey was carried out for the first time in China, and through analyzing dataset from the survey, this study was set up to test both China’s regional inequity in pharmacist’s drug safety practice and major influencing factors for pharmacist’s drug safety practice among different districts of China. Results Pharmacist’s drug safety practice in regions with higher per capita GDP and more abundant medical resources was still better than that in regions with lower per capita GDP and less abundant medical resources. In all districts of China, pharmacist’s drug safety knowledge, drug safety attitude, self-perceived pressure and fatigue, hospital management quality, and hospital regulation were major influencing factors for pharmacist’s drug safety practice, while only in regions with higher per capita GDP and more abundant medical resources, hospital drug safety culture, supervisor’s work team management, cooperation atmosphere of work team, and drug safety culture of work team were major influencing factors for pharmacist’s drug safety practice. Conclusion Regional inequity in pharmacist’s drug safety practice still existed in China. In all districts of China, promoting pharmacist’s drug safety knowledge, drug safety attitude, self-perceived pressure and fatigue, hospital management quality, and hospital regulation could help promote pharmacist’s drug safety practice, while only in regions with higher per capita GDP and more abundant medical resources, promoting hospital drug safety culture, supervisor’s work team management, cooperation atmosphere of work team, and drug safety culture of work team could help promote pharmacist’s drug safety practice. And in regions with lower per capita GDP and less abundant medical resources, the link between pharmacist’s drug safety practice and hospital drug safety culture/supervisor’s work team management/cooperation atmosphere of work team/drug safety culture of work team should also be gradually established.
