This paper selects the Changsha-Zhuzhou-Xiangtan region(Chang-Zhu-Tan) consisting of 23 county-level units) as a case study and looks at its economic development, agricultural product supply, social security and ecological service functions during 1996–2016. It then constructs an index system to evaluate the temporal evolution of the region’s rural functions. SPSS 19.0 and DPS 7.05 software, as well as Pearson’s correlation coefficient analysis, system clustering, optimal segmentation of ordered samples and other methods, are used to study the evolution traits, regional differentiation characteristics and driving forces of rural functions in the region. The results show, first of all, that the overall evolution trend is increasing in functions with periodic characteristics, the key nodes being 2000 and 2008. Second, there is clear geographical differentiation in the evolution of rural functions. The economic development function shows rapid growth in the urban agglomeration’s center and relatively weak growth at the periphery;the agricultural product supply function and ecological service function are concentrated in county-level units with abundant cultivated and forest land;and the social security function displays similar geographical differentiation to the economic development function. Overall, there is an obvious discrepancy in the degree of development of rural functions among county-level units of the Changsha-Zhuzhou-Xiangtan urban agglomeration;the rural functions of the agglomeration and peripheral county-level units have different development traits;and county-level units display functional differentiation. Third, rural functions have evolved as a result of interactions between various factors, such as natural resources, socio-economic conditions and local transport conditions. The new driving forces caused by urbanization are ultimately leading the evolution of rural functions toward multi-functional comprehensive development.展开更多

This study explored the spatiotemporal evolution of the productive function of three rural settlements, i.e.,Hetaoyuan, Dawengshan, and Gaoqiao, in the Yimeng Mountain in Shandong province of eastern China.Residents lived in this three types of rural settlements were all involved in agricultural production(i.e., grain threshing, drying and storage), which had remained dominant in Hetaoyuan. Dawengshan became an industrial-oriented settlement, while Gaoqiao became a commercial-oriented settlement. This evolution was reflected in the livelihood strategy changes of rural households and the transition of rural settlements changes. The choice of livelihood strategy was affected by the livelihood assets and policies, which resulted in the spatiotemporal evolution of the productive function of rural settlements. This study can provide references for the implementation and adjustment of rural residential land consolidation policies and the improvement of production and the quality of rural life in future.展开更多

Taking rural settlement Raosi Village in Hengduan Mountains as a case study, and on the basis of the synthetic research into the ecological process of the complex ecosystem, the study shows that energy costs of production, human living and ecology functions are separately taking 1.36%, 13.59% and 85. 05% of the gross ecosystem functions, and the exertions of production and human living functions are close to a high-point state on the present using level of energy in the settlement. The study also shows that the most important function of a rural settlement in mountain area is its ecological rather productive function.展开更多

They have increasingly been valuable for their goods and services, and the intrinsic ecological value they provide to local populations, as well as people living outside the periphery of the wetlands. Stakeholders＇ participation is essential to the protection and preservation of wetlands because it plays a very important role economically as well as ecologically in the wetland system. The objective of this study was to determine whether gender, educational status, mouzas （which are constituents of a block according to the land reform of the West Bengal Government in India）, and wetland functions have any influence on the annual income of the local community. Considering a floodplain wetland in rural India, the focus was extended to recognize the pattern of wetland functions according to the nature of people＇s involvement through cluster analysis of the male and female populations. Using the statistical software R-2.8.1, an ANOVA （analysis of variance） table was constructed. Since the p value （significance level） was lower than 0.05 for each case, it can be concluded that gender, educational status, mouzas, and wetland functions have a significant influence on annual income. However, S-PLUS-2000 was applied to obtain a complete scenario of the pattern of wetland functions, in terms of involvement of males and females, through cluster analysis. The main conclusion is that gender, educational status, mouzas, and wetland functions have significant impacts on annual income, while the pattern of occupation of the local community based on wetland functions is completely different for the male and female populations.展开更多

The fact that it is predominantly manually harvested exposes the workers to a variety of health hazards. Since the harvest is a labor activity that exacts from the worker a heavy physical toll, involving the exertion of quick, repetitive movements that intensely overburden both one’s muscles and skeletal frame. Objective: To assess the health profile and functional independence in former workers who operated in a biofuel plant in Bahia. Methods: This is a descriptive, exploration-oriented study conducted with 42 workers formerly employed as cane cutters, both male and female and over 18 years old, all of them living in the town of Amélia Rodrigues (BA). The self-administered Nottingham Health Profile (NHP) was used to measure their quality of life, based on the World Health Organization’s classification of disabilities;the Functional Independence Measure (FIM) metrics was employed to keep track of functional independence. The FIM focuses on two aspects, motile and cognitive, subdivided further into categories designed to assess individual independence in tackling basic activities effectively and satisfactorily. Results: 42 individuals were assessed, most of them men (54.8%), predominantly adults (73.8%) of African descent (61.9%). Evidence, along with the correlation coefficient to analyze the FIM and the NHP, presents a significance level of 0.05 in the categories: Total NHP, Energy Level, Pain and Physical Abilities. Conclusion: This study found that there is harm to the health of former cane cutters as far as their sleep, energy levels and physical abilities are concerned. With these remarks, the authors expect to motivate health surveillance efforts regarding the risks in those work environments and the associated health issues, so that preventive and interventive public health measures can be implemented.展开更多

Results: 42 individuals were assessed, most of them men (54.8%), predominantly adults (73.8%) of African descent (61.9%). Evidence, along with the correlation coefficient to analyze the FIM and the NHP, presents a significance level of 0.05 in the categories: Total NHP, Energy Level, Pain and Physical Abilities. Conclusion: This study found that there is harm to the health of former cane cutters as far as their sleep, energy levels and physical abilities are concerned. With these remarks, the authors expect to motivate health surveillance efforts regarding the risks in those work environments and the associated health issues, so that preventive and interventive public health measures can be implemented.

文摘Cognitive function in the elderly is affected by various environmental,social,and individual factors.Studies show that chemical trace elements are closely related to cognitive function.As a protective factor,selenium promotes cognition in the elderly.However,study results into the effects of selenium on cognition have varied.By eliminating unstable environmental and other related factors,the present study selected elderly individuals from rural areas of the Shandong province to verify whether low selenium exposure is a risk factor for decreased cognitive function.Results demonstrated that age,sex,education,occupation,hypertension,stroke,and body selenium levels were factors affecting cognitive function in the elderly,and that selenium was an important protective factor.Moreover,results supported the hypothesis that a lifelong low selenium level is associated with low cognitive function.
