Background: Currently, China is in the process of medical and health care reform, and the establishment of primary medical and health services covering urban and rural residents is an important aspect of this process. Studying the satisfaction of residents of underdeveloped areas with their primary medical and health services and identifying the factors that can increase the satisfaction of different groups may improve patient compliance and ultimately improve health. Moreover, such research may provide a reference for the development of medical and health undertakings in similarly underdeveloped areas. Methods: A face-to-face survey was conducted on a stratified random sample of 2200 residents in Gansu by using structured questionnaires. Demographic characteristics were collated, and questionnaires were factor-analysed and weighted using SPSS software to obtain scores for each factor, as well as total satisfaction scores. The characteristics of poorly satisfied populations were determined by a multiple linear regression analysis using SAS software. A cluster analysis was performed using SAS software for classification and a separate discussion of populations. Results: The hypertension self-awareness rate (11.29%) of the sampled population was lower than the average hypertension prevalence (23.85%), as recorded in the 2014 Health Statistical Yearbook of the region. The disease knowledge awareness factor was the lowest factor (2.857), whereas the policy awareness factor was the highest factor (4.772). The overall satisfaction was moderate (3.898). The multivariate linear regression model was significant (p <0.05). The regression coefficients were -0.041 for minors; 0.065 for unemployed people; and 0.094 for people with an elementary school educational level, a value lower than that of other population groups. A cluster analysis was used to divide the respondents into five groups. The overall satisfaction was lowest in the second population group (rural, middle-aged)(Fz = 3.64) and was highest in the fourth population group(minors) (Fz = 4.13). Different population groups showed different satisfaction rates in F1 to F6. Conclusion: Hypertensive patients had low self-awareness, and residents had a poor grasp of disease and limited health knowledge. Their overall satisfaction was moderate. Residents expressed comparatively high satisfaction with the current policy. Minors, adults with low level of education, unemployed people and other vulnerable groups expressed low overall satisfaction. The degree of satisfaction varied greatly among the different groups. Targeted medical and health practices should be implemented for different groups; additionally, the public health practice should be strengthened.

Abstract： 10 A fluorescence system is developed by using several light emitting diodes (LEDs) with different 11 wavelengths as excitation light sources. The fluorescence detection head consists of multi LED light 12 sources and a multimode fiber for fluorescence collection, where the LEDs and the corresponding 13 filters can be easily chosen to get appropriate excitation wavelengths for different applications. By 14 analyzing fluorescence spectra with the principal component analysis method, the system is utilized in 15 the classification of four types of green tea beverages and two types of black tea beverages. Qualities of 16 the Xihu Longjing tea leaves of different grades, as well as the corresponding liquid tea samples, are 17 studied to further investigate the ability and application of the system in the evaluation of 18 classification/quality of tea and other foods.19

In this paper, we develop novel pixel distribution and plane-light-path structures for optical fibre process tomography, which can be used to measure medium distributions and contents in a circular cross section of cylindrical space in the field of industry process monitoring and control. Such structures partition the circular region into two parts: one is a ring-measured part including 60 pixels; the other is a centre unmeasured part corresponding to a mechanical supporting pole. Eight optical fibre sensor units are uniformly distributed around the circle, each consisting of six transmission fibres. A simple numerical model of stratified two-phase flow is employed to provide the projected data for image reconstruction and verify the feasibility of the novel structures. Reconstructed images are obtained in the presence of an algebraic iterative reconstruction algorithm, and they are basically in accordance with the original models. Theoretical image-reconstructed relative resolution, taking into account the 60 pixels, is 1.67%. However, we found that the reconstructed error is less than 5%.
