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.

International Journal for Equity in Health , 2012, DOI: 10.1186/1475-9276-11-38
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.
A Model for Regional Energy Utilization by Offline Heat Transport System and Distributed Energy Systems—Case Study in a Smart Community, Japan  [PDF]
Liyang Fan, Weijun Gao, Zhu Wang
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.53019
Abstract:

Under the Kyoto Protocol,Japanwas supposed to reduce six percent of the green house gas (GHG) emission in 2012. However, until the year 2010, the statistics suggested that the GHG emission increased 4.2%. What is more challenge is, afterFukushimacrisis, without the nuclear energy,Japanmay produce about 15 percent more GHG emissions than1990 inthis fiscal year. It still has to struggle to meet the target set by Kyoto Protocol. The demonstration area of “smart community” suggests Japanese exploration for new low carbon strategies. The study proposed a demand side response energy system, a dynamic tree-like hierarchical model for smart community. The model not only conveyed the concept of smart grid, but also built up a smart heat energy supply chain by offline heat transport system. Further, this model promoted a collaborative energy utilization mode between the industrial sector and the civil sector. In addition, the research chose the smart community inKitakyushuas case study and executed the model. The simulation and the analysis of the model not only evaluate the environmental effect of different technologies but also suggest that the smart community inJapanhas the potential but not easy to achieve the target, cut down 50% of the CO2 emission.

On the Insufficiency of Government Medical and Health Care Expenditure of China: A Stochastic Frontier Analysis Based on Provincial Panel Data
Wang An,Hong Liyang
Research Journal of Applied Sciences, Engineering and Technology , 2013,
Abstract: This study sets up a deterministic model of the optimal government medical and health care expenditure amount and then adopts the provincial panel data of China from 1999-2009 to study the insufficiency problem of government medical and health care expenditure with the help of stochastic frontier analysis (hereinafter referred as SFA) technique. Our result indicates that judging from both provincial level and national average level, although it has been alleviated during these years, there is still a huge gap between actual government expenditure and its optimal amount. We also find that the higher the degree of fiscal decentralization, the closer is the medical and health care expenditure to its optimal level. In addition, urbanization in China aggravates the insufficiency problem.

Jingbo Guo, Yuping Duan, Lidong Liu, Liyang Chen, Shunhua Liu
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2011, DOI: 10.4236/jemaa.2011.35023
Abstract: Carbonyl-iron/Fe91Si9 composites for thin microwave absorbers were firstly prepared by a simple blending technique. The patterns of carbonyl-iron and Fe91Si9 were characterized by scanning electron microscope (SEM). The complex permittivity, permeability and microwave absorption properties of the composites were studied in the frequency range of 2 - 7GHz by a HP8720B vector network analyzer. Complex permittivity and permeability decrease gradually with increasing weight percentage of Fe91Si9 in the composites, the variation of permittivity was very large but the variation of permeability was very small. The composites exhibited excellent microwave absorption properties with increasing Fe91Si9 content. The reflection loss (RL) values less than –20 dB were obtained in the 3.7 - 6.7 GHz frequency range for the paraffin matrix composites with 80 wt% carbonyl-iron/Fe91Si9 powders (weight ratio of carbonyl-iron to Fe91Si9 was 1:1), with thickness of 4.0 - 2.4 mm, respectively. The optimal RL of –45 dB was observed at 5.2 GHz with a matching thickness (dm) of 3.0 mm. The excellent microwave absorption properties were attributed to a better electromagnetic impedance match and a higher electric resistivity.

Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.38121
Abstract: This paper is to provide an empirical work for agricultural spatial distribution of agriculture. We consider the spatial location pattern in order to offer spatial views on the agricultural economic research and how Chinese agricultural economic spatial location pattern is forming, we also tested the agglomeration situation of agriculture and the process is going on in the future. The results indicate that the periphery areas exist significant differential among regions in Hunan province, China. It really presents some kinds of agglomeration pattern of agriculture and characteristic spatial autocorrelation; the biggest rate of contribution to the region agriculture economic gap is productivity per agriculture worker.

Abstract: Two Web search tools, namely, AltaVista and Sohu, were evaluated and compared in terms of their composition of Web indexes, search capability, retrieval performance, output option, and user effort. Recall is deliberately omitted from this study because for a particular query it is impossible to assume how many relevant items there are in the huge and ever changing Web system. In addition, the author introduces two new parameters, e.g. duplicate links and dead links, for the evaluation. As a result, the author analyses the gap between Chinese and English Web search tools and indicates the different evaluation methodologies between them.
