Carbon ecological security assessment based on the decoupling relationship between carbon balance pressure and ecological quality in Xuzhou City, China.

Building a carbon ecological security (CES) framework helps to scientifically evaluate and manage the regional carbon cycle and eco-environment and support regional ecological security patterns. This paper adopted the pressure-state-response-immune (PSRI) model and the carbon balance index method to evaluate the ecological quality and carbon balance pressure. Then, based on the decoupling model and the improved four-quadrant model, the CES framework was constructed to evaluate the changing trend of the CES of Xuzhou City from 2005 to 2020. The results showed that the carbon balance pressure of Xuzhou City showed a pattern of "low-high-low" from east to west, and most areas tended to have a carbon balance and surplus in 2020. The ecological quality showed an overall upward trend during the study period. Protection and restoration drove the response and immune index growth from 2010 to 2020. In the Thirteenth Five-Year Plan stage, the nine districts of Xuzhou City were in a stable decoupling state, and the overall decoupling process was ideal. The CES of districts showed individual differences in the general upward trend. The carbon balance pressure of Gulou and Quanshan Districts was the main factor restricting the districts' CES. Therefore, based on the empirical results, this research proposes relevant suggestions to enhance carbon ecological security to achieve regional green and low-carbon development.

Epidemic characteristics of student tuberculosis in Xuzhou, Jiangsu, 2016-2020 / 中国热带医学

@#Abstract: Objective　The tuberculosis data of students registered and reported in Xuzhou from 2016 to 2020 were analyzed to provide a basis for Xuzhou to formulate tuberculosis prevention and control measures in schools. Method　The epidemiological characteristics of tuberculosis among students in Xuzhou from 2016 to 2020 were analyzed based on the data from Tuberculosis Information Management System and Xuzhou Statistical Yearbook 2021. Results　From 2016 to 2020, a total of 574 student tuberculosis patients were registered in Xuzhou, with an annual average registration rate of 5.64/100 000. The reported incidence of tuberculosis among students in Xuzhou showed an increasing trend year by year (χ2trend=22.521, P<0.001). There were 365 males and 209 females, respectively, with a sex ratio of 1.75:1. The tuberculosis patients were mainly in the 15-19 years old group and 20-24 years old group. According to the statistical analysis by different levels of education, students from ordinary higher institutions accounted for 48.61% of the total number of confirmed cases, followed by senior high schools and secondary vocational schools, accounting for 20.91% and 14.46%, respectively. Preschool education had the lowest number of confirmed cases, accounting for 1.05%. There was significant difference in the reported incidence of tuberculosis among students at different educational levels (χ2=1 522.39, P<0.001). The highest incidence was reported in ordinary higher institutions, followed by senior high schools and secondary vocational schools, and the lowest incidence was reported in preschool education. Conclusion　Xuzhou city school tuberculosis epidemic integral is on the rise, we should further strengthen tuberculosis control work of school tuberculosis prevention and control measures of implementation in the future, at the same time to strengthen school tuberculosis prevention knowledge propaganda and standardize the schools for disposal of tuberculosis epidemic situation. We should also further strengthen the newborn matriculation examination and students absent from class because of illness monitoring work.

Study on middle-aged and elderly people′ willingness for family doctor contracting and its influencing factors / 中华医院管理杂志

Objective:To investigate the middle-aged and elderly people′ willingness for family doctor service contracts and its influencing factors, and to provide feasible suggestions for the implementation and promotion of family doctor services.Methods:Stratified random sampling method was adopted to select middle-aged and elderly people aged 45 in 6 urban areas of Xuzhou city for questionnaire survey to investigate their illness, medical treatment and their willingness to contract a family doctor. The data acquired were analyzed with statistical description, univariate analysis( χ2 test), and multivariate logistic regression analysis. Results:Among the 927 valid questionnaires were recovered, 272(29.34%)of them intended to contract a family doctor, and 655(70.66%)had no such intention. Results of multivariate logistic regression showed that the influencing factors of the middle-aged and elderly people′ willingness of contracting family doctors were age, occupation, self-rated health, treatment status within two weeks, chronic diseases, referral experience and their knowledge of family physician contract system.Conclusions:Middle-aged and elderly people at large are not willing to sign up for family doctors. It is recommended to focus the publicity efforts on those who are relatively younger age, farming and healthier, enhancing their awareness of the service, and encouraging them to support the dual-referral policy. These efforts are expected to promote the coordinated progress of both dual referral and family doctor contract service, hence achieving the national coverage of the family doctor system.

Risk factors of obesity in children aged 5-14 years in Xuzhou and early intervention measures / 公共卫生与预防医学

Objective To explore the risk factors and early intervention methods of obesity in children aged 5-14 years in Xuzhou. Methods Children from 3 urban areas were randomly selected from Xuzhou City for physical measurement. The children were divided into obese group and normal group based on 2 standard deviations of WHO standard weight. A questionnaire survey was used to assess the risk factors for obesity in children aged 5 to 14, and early intervention measures were put forward. Results The detection rate of obese children in this group was 53.00%. Single factor analysis showed that breastfeeding, supplementary food addition at 4 and 6 months, fast eating, preference for dessert, drinks and fried foods, sleep time <8h/d, dislike of sports, daily TV watching time ≥ 2h / d, obesity of father and mother, mother's education level, and parents' obesity cognition were related to obesity in children aged 5-14 (P <0.05) . Logistic regression analysis revealed that artificial feeding, fast eating, deep frying, sweet drinks, mother's education, father's obesity and mother's obesity were high risk factors of children's obesity. Conclusion The incidence of obesity in children aged 5-14 years old in Xuzhou was high. Early feeding mode, children's preference for fried desserts, parents' obesity and mother's education level were the main risk factors for children's obesity. It is suggested that communities promote more health education on children’s obesity.

[Multi-scale effects of urban landscape pattern on plant diversity in Xuzhou City, Jiangsu Province, China.] / å¾å·žåŸŽå¸‚æ™¯è§‚æ ¼å±€å¯¹ç»¿åœ°æ¤ç‰©å¤šæ ·æ€§çš„å¤šå°ºåº¦å½±å“.

The changes of urban surface landscape will lead to damage, fragmentation, and losses of biodiversity, resulting in urban biodiversity decline. In order to explore the responses of urban plant diversity to the changes of landscape pattern, we chose the urban area surrounded by round-city highway as research object, set 36 plots in different directions with the Gupeng Square as the center, investigated the plant group in each of the plots through coverage rank method of Braun-Blanquet, and examined the features of plant species diversity in Xuzhou's greenlands. Meanwhile, we divided the landscape of the research area into seven categories: buildings, grasslands, forest lands, waste lands, water areas, roads and farmlands with the help of Erdas, GIS software and Landsat TM remote sensing images from 2005 to 2015 as basic data source. The features of landscape pattern in the research area were analyzed by Fragstats software. We set nine different buffer districts within each of the sample plot by applying the space analyzing function of GIS, calculated 39 landscape pattern metrics using Fragstats, and explored the features of how plant diversity responsed to landscape pattern. After that, the landscape pattern metrics with significant influence on the plant diversity of urban greenlands under different extents were selected by redundant analysis (RDA). The results showed that the plant diversity had obvious temporal and spatial scale effects in responses to landscape pattern and landscape elements. In 2005, the patch area and shape metrics of unused land and farmland could better explain plant diversity in 800 m buffer zone. The patch fragmentation and connectivity metrics of construction land had significant impacts on plant diversity within the extent of 800-2000 m. In 2015, grassland and forest landscapes better explained plant diversity in the 800 m buffer zone while construction sites and unused land had a remarkable impact on plant diversity in the extent of 1000-2000 m. The current plant diversity was more strongly influenced by the 2005 landscape type metrics, indicating that the plant diversity lagged in its response to the changes of landscape pattern. The pattern metrics of landscape level were more consistent with the landscape-class level metrics, indicating that the interaction between species and spatial scale was more dependent on the landscape type. This study would provide effective decision-making information for Xuzhou City planning and construction as well as effective protection of urban green space biodiversity.

Enhanced recycling network for spent e-bicycle batteries: A case study in Xuzhou, China.

Electric bicycles (e-bicycles) are a primary means of commuting in China because of their light weight, speed, and low maintenance costs. Owing to short service life and environmental pollution hazards, recycling and reuse of e-bicycle batteries has always been a focus of industry and academia. As a typical case of both production and use of large electric bicycles, 113 major sellers, 378 corporate and individual buyers, 147 large e-bicycle repair centers, and 1317 e-bicycle owners in Xuzhou City were investigated in order to understand the sales, use, recycling, and disposal of spent e-bicycle batteries. The findings show that the existing distempered recycling system is the main limitation of spent battery recovery, and the actual recovery rate of spent batteries is lower than the estimated output (QW) for the years 2011-2014. Electric bicycle sellers play a fundamental role in the collection of spent batteries in Xuzhou, accounting for 42.3±8.3% of all batteries recovered. The widespread use of lithium batteries in recent years has resulted in a reduction in spent battery recycling because of lower battery prices. Furthermore, consumer preferences are another important factor affecting the actual recovery rate according to survey results evaluated using canonical correspondence analysis. In this paper, we suggest that a reverse logistics network system for spent battery recycling should be established in the future; in addition, enhancing producer responsibility, increasing publicity, raising of public awareness, developing green public transport, and reducing dependence on e-bicycles also should be pursued. This study seeks to provide guidance for planning construction and management policies for an effective spent battery recycling system in China and other developing countries.

Objective To investigate the status of knowledge,attitude and practice(KAP)of foodborne parasitic diseases among middle school students in Xuzhou City,so as to provide a reference to the health education. Methods A total of four middle schools were selected and their students were investigated with the basic information questionnaire and questions of food-borne parasitic diseases. Results The awareness rates of parasitic diseases,hazards and transmission were 56.50％,66.33％and 70.50％respectively. The awareness rates of transmission of the diseases in the senior high school students and urban students were higher than those in the junior middle school students and rural students(χ2 =8.684,8.470,both P<0.05). The forma-tion rates of not drinking raw water and not eating raw food were higher among the female students than those among the male stu-dents(χ2 =7.675,15.230,both P<0.05). The formation rate of not eating raw food was higher among the senior high school students than that among the junior middle school students(χ2 =49.276,P<0.001),and the formation rates of washing hands before meals and not keeping pets were higher among the urban students than those among the rural students (χ2 = 5.833, 13.443,both P<0.05). Totally 64.83％of the students would not eat food that might be infected with foodborne parasites,and the proportion of girls was higher than that of the boys(χ2 =11.690,P<0.05),and 20.5％of the students would suggest others not eating food that might be infected with foodborne parasites,and 81％of the students would plan to get rid of bad habits. Con-clusion The cognition of foodborne parasitic diseases is poor among the middle school students in Xuzhou City. The health edu-cation work on foodborne parasitic diseases should be strengthened.
