Healthcare relief teams dispatched to rural areas often face difficulties due to limited initial and ongoing health information in the affected community.The present study investigated patterns of healthcare service demand for a rural displaced population in a post-disaster situation.Three weeks after the 2014 Ludian County earthquake,the Institute for Disaster Management and Reconstruction(IDMR) at Sichuan University and Hong Kong Polytechnic University organized a disaster nursing team to support the rural community in Longtoushan,at the epicenter of the earthquake.A cross-sectional,records-based study of 2484 records obtained from a temporary hospital in Longtoushan(for the period of 14 September-1 October 2014) was conducted.The daily number of records by patients' sociodemographic characteristics and medical diagnoses were plotted on a time series graph to explore the temporal change during the study period.Findings indicate that healthcare service demand from younger age groups was higher than that of the older adult group.Three major health problems were observed:respiratory disease,skin problems,and ear,eye,and throat(EET) problems.All of these very real health problems are chronic issues that require long-term care.They are not health issues directly related to the disaster emergency itself.Yet disaster relief nursing teams were selected on the basis of their ability to cope primarily with traumatic disaster-related injuries.The existing practice of teaming up disaster relief professions might not be optimal.To better understand the healthcare needs of a displaced population,short- and long-term planning is needed.Planning will allow disaster response professionals to better organize and deploy healthcare personnel to manage the above-listed problems in a postdisaster situation. 展开更多

The relationship between the supply and demand for ecosystem services(ESs)is a key issue for the rational allocation of natural resources and optimisation of sustainable development capacity.This paper investigateed the dynamic evolution features of supply and demand of four ESs in Lanzhou of China,namely,water supply,food supply,carbon fixation and soil retention services.The crosssectional data of 2005 and 2017 were used for calculating ESs value and its supply and demand through ArcGIS software,InVEST model,elastic coefficient model and coupling coordination model.Results showed that:1)from 2005 to 2017,the supply of water supply services increased,the demand of soil retention services decreased,and the supply and demand of food supply and carbon fixation services increased.The high-value areas of service supply were mainly distributed in the rocky mountain areas in the southeast and northwest with high vegetation coverage,while the high-value areas of demand were mainly distributed in the urban areas and surrounding areas with high population density.2)There were five different types of coupling relations.Water supply service was dominated by a negative coupling type D,which means that the decrease in demand for ESs has had a positive response on the supply of ESs.Negative coupling type C was the main type of food supply and carbon fixation services,which means that the increase in demand for ESs has had a negative response on the supply of ESs.All three services were supplemented by a positive coupling type A,which means that the increase in demand for ESs has had a positive response on the supply of ESs.Soil retention service generally exhibits a positive coupling type B,which means that the decrease in demand for ESs has had a negative response on the supply of ESs.3)Over the past 12 yr,the coordination degree of supply and demand of water supply,food supply and soil retention services decreased,and the coordination degree of carbon fixation service increased.Various types of ES had a low degree of coupling and coordination,showing different characteristics of temporal and spatial evolution.The areas with imbalanced ESs supply and demand were mainly distributed in urban areas dominated by construction land.The research results are valuable to the optimisation of urban and rural ecological environments and the sustainable development of territory space under the framework of ecological civilisation,including similar ecologically vulnerable areas in other developing countries. 展开更多

The empirical research is conducted in the sample of high-value customers in China mobile market. Based on Lewin behavior model, this pa- per establishes factors-matrix from personal and environmental dimensions. Relationships among multiple factors are tested in the structural equa- tion model and their impacts on customers' de- mands are elaborated. Findings indicate that opera- tional convenience and business brand image have significant effects on sample users' demands. Fur- thermore, annual income, gender, occupation, the needs of access to information and the needs of enriching and improving social relationships are al- so important factors for high-value users. The re- suits may provide further insights into mobile service demand and the model can be popularized to other behavior researches. 展开更多

The spatial relationships between traffic accessibility and supply and demand(S&D)of ecosystem services(ESs)are essential for the formulation of ecological compensation policies and ESs regulation.In this study,an ESs matrix and coupling analysis method were used to assess ESs S&D based on land-use data for 2000,2010,and 2020,and spatial regression models were used to analyze the correlated impacts of traffic accessibility.The results showed that the ESs supply and balance index in the middle reaches of the Yangtze River urban agglomeration(MRYRUA)continuously decreased,while the demand index increased from 2000 to 2020.The Gini coefficients of these indices continued to increase but did not exceed the warning value(0.4).The coupling degree of ESs S&D continued to increase,and its spatial distribution patterns were similar to that of the ESs demand index,with significantly higher values in the plains than in the montane areas,contrasting with those of the ESs supply index.The results of global bivariate Moran’s I analysis showed a significant spatial dependence between traffic accessibility and the degree of coupling between ESs S&D;the spatial regression results showed that an increase in traffic accessibility promoted the coupling degree.The present results provide a new perspective on the relationship between traffic accessibility and the coupling degree of ESs S&D,representing a case study for similar future research in other regions,and a reference for policy creation based on the matching between ESs S&D in the MRYRUA. 展开更多

Background: Treatment is an important component of a comprehensive cancer control approach and its outcomes strongly depend on infrastructure, equipment, human and financial resources available. Therefore it is imperative to generate evidence-based tools to assist health policy makers from low resourced countries in planning efficient and equitable treatment services for a defined population based on what it is feasible to these settings. Methods: The intended cancer spe-cific treatment planned and written in the patients’ medical record (treatment prescription) of untreated adult cancer cases (≥18 years of age), excluding non-melanoma skin cancer, was recorded in a chronological way from 1 January 2012 onwards in a group of eight comprehensive cancer centres located in middle income countries and offering the main modalities of cancer treatment (surgery, medical oncology and radiotherapy). Results: A total of 17,713 medical records were reviewed, of which 7106 (54.2%) met the eligibility criteria. Prescription of main cancer treatment modalities were distributed as follows: 57.6% for chemotherapy (n = 4093), 56.8% for surgery (n = 4038), and 46.8% for radiotherapy (n = 3327). There was a predominance of plans consisting of combined treatment modalities over monotherapy (55.2% versus 44.8%). At the time of diagnosis 54.3% of the cancer cases had disease that had spread beyond the primary site, 41.2% were considered as having local disease and in 4.5% of the cases the information on disease extension was unknown. Conclusions: The results obtained should be seen as an approximation of cancer treatment service demand based on what it is currently practiced and therefore feasible in developing countries, particularly in middle income countries. 展开更多

China's energy service demand statistics for the passenger transport sector only cover travel activities for business purpose.The incomplete data have made it very difficult to conduct long-term scenario analysis for this sector.Thus,this study develops a methodology by refining and combining vehicle activity and travel behavior methods.By taking advantage of the two methods,the extent of uncertainty in estimates can be reduced.A detailed description of China's energy service demand in the passenger transport sector for the years 2013,2015,and 2017 are produced.Results show that there is a significant underestimation of total passenger transport turnover in governmental statistics.After reevaluation,the total passenger turnover doubled and increased by 146%,167%,and 187%,resulting in national total passenger turnover of 6783,8031,and 9406 billion passenger kilometers in 2013,2015,and 2017,respectively.The majority of missing statistics are caused by not accounting for non-operational road transport,which is dominated by private vehicles.After adjustment,the road sector share in total passenger turnover grew substantially from 30%to 40%to approximately 75%,with the proportion of urban travel continuing to increase.We found that without complete data on China's passenger turnover,it may result in more than three-fold overestimation for future travel demand,leading to inaccurate projections with much higher energy consumption and CO_(2) emissions.It is therefore very important to have a detailed and precise calculation of energy service demand in the passenger transport sector.The estimation framework and step-by-step process can also be applied to other developing countries which are confronting similar statistical issues. 展开更多

OBJECTIVE: To provide insight into the psychosocial factors underlying the utilisation of health services by women with reproductive tract infection (RTI) symptoms. METHODS: A cross-sectional study, adopting Aday and Andersen' s Social Behaviour Model, was conducted between 1998 and 1999 in Chinese Hebei province and Beijing. A total of 864 eligible married women (age 21 to 60 years) were face to face interviewed. RESULTS: The percentage of self-reported symptoms of RTIs in urban and rural women was 35.6 and 46.8, respectively; the proportion of women with RTIs who utilised health services was 27.5% and 26.7%, respectively. Compared to urban women, rural women had less knowledge on RTIs and more traditional beliefs, and were more satisfied with local health services. The results of logistic regression analysis showed that the common factor influencing health service utilisation in women with RTIs was current experience of RTIs. Knowledge about self-medication, perceived social stigma attached to RTIs, prior experience of RTIs, family income and perceived severity of RTIs were also predictors of utilisation of health services in rural women with RTIs. Satisfaction with health providers, information received from health providers, prior experience of RTIs, occupation and medical care coverage were predictors of utilisation of health services in urban women with RTIs. CONCLUSION: The prevalence of RTIs is high, but the rate of seeking health services is low. There is a great need for emphasizing culturally acceptable reproductive health education in different places to improve women' s ability for self-care. Regular medical check-ups for women are also important. It is necessary to improve the quality of health service, complete the reform of health insurance and alleviate women' s social stigma related to RTIs, giving women social and moral support. 展开更多

The destruction of the ecological system caused by urban expansion has led to the environmental deterioration,cities have become increasingly vulnerable.In this study,six districts and counties along the Yellow River in Zhengzhou were selected as the study area.First,green infrastructure elements were extracted by morphological spatial pattern analysis.Then,outside the urban areas,we used connectivity analysis to evaluate the importance of core areas,adopted minimum cumulative resistance model to extract potential corridors,and identified the important corridors by using the gravity model.Finally,in the urban areas,we set up an evaluation system to assess the demands for ecosystem services.The results showed that:(1)Seven landscape types of green infrastructure be identified in study area.(2)There are 17 vital cores,136 potential corridors,and 24 vital corridors outside the urban areas.(3)The blocks with high demand for ecosystem services are mostly concentrated in the old blocks with dense populations and poor infrastructure,and there are 5 blocks with comprehensive high-demand.Based on identified importance for green infrastructure land space,and high-demand level for ecosystem services areas in this study,a green infrastructure net plan was proposed based on spatial conservation prioritisation. 展开更多
