The aim of our study is to determine the distribution of 10-year risk for ischemic cardiovascular disease (ICVD) among middle-aged Chinese adults, and to evaluate the usefulness of global risk assessment tools in the primary prevention of ICVD in Chinese population.Methods Simplified prediction tools derived from the USA-PRC Collaborative Study of Cardiovascular Epidemiology cohort were applied to the Chinese Health Examination Database (CHED) 2008. 10-year risk for ICVD was estimated in 461 157 ICVD-free subjects (264 432 male and 196 725 female) aged 35 to 59 years. Results Among the male subjects, 82.4% had a 10-year risk for ICVD of 〈5%, 14.4% of 5% to 12.1% and 3.4 of≥ 12.2%, and in female subjects, 86.7% had a 10-year risk for ICVD of 〈5%, 12.1% of 5% to 12.0% and 1.2% of ≥ 12.1%. All subjects with predicted high level ICVD risk (≥ 12.2% in male or ≥ 12.1% in female) had either remarkably elevated (≥ 160 mmHg) blood pressure, significantly increased (≥ 6.22 mml/L) total serum cholesterol or diabetes.Conclusion Using the currently recommended prediction tools, only very small proportions of middle-aged Chinese men and women who were free of ICVD would be classified into high level risk group. These prediction tools are unlikely to help for the medical intervention decision making in Chinese adult patients with hypertension and/or hypercholesterolemia展开更多

To balance human needs with ecosystem needs, this study proposes an ecologically oriented operation strategy for a multi-reservoir system that integrates environmental flow requirements into the joint operation of a multi-reservoir system in order to main- tain different ecological functions throughout the river. This strategy is a combination of a regular opti-mal operation scheme and a series of real-time ecological operation schemes. During time periods when the incompatibilities between human water needs and ecosystem needs for environmental flows are rel- atively small, the regular optimal operation scheme is implemented in order to maximize multiple human water-use benefits under the constraints of a minimum water-release policy. During time periods when reservoir-induced hydrological alteration imposes significant negative impacts on the river's key ecological functions, real-time ecological operation schemes are implemented in order to modify the out- flow from reservoirs to meet the environmental flow requirements of these functions. The practical use of this strategy is demonstrated for the simulation operation of a large-scale multi-reservoir system which located in the middle and lower Han River Basin in China. The results indicate that the real-time ecological operation schemes ensure the environmental flow requirements of the river's key ecological functions, and that adverse impacts on human water-use benefits can be compensated for by the regular optimal operation scheme. The ecologically oriented operation strategy for a multi-reservoir system that is proposed in this study enriches the theoretical application of the multi-reservoir system joint operation which considers environmental flow requirements.展开更多

For the site selection problem of emergency material warehouses, the triangular fuzzy numbers are respectively demand of the demand node, the distance between the warehouse and demand node and the cost of the warehouse, a bi-objective programming model was established with minimum total cost of the system and minimum distance between the selected emergency material warehouses and the demand node. Using the theories of fuzzy numbers, the fuzzy programming model was transformed into a determinate bi-objective mixed integer programming model and a heuristic algorithm for this model was designed. Then, the algorithm was proven to be feasible and effective through a numerical example. Analysis results show that the location of emergency material warehouse depends heavily on the values of degree a and weight wl. Accurate information of a certain emergency activity should be collected before making the decision.展开更多

These recreations symbolize not only a privileged visual interpretation of a nation, but they also allow us to examine how a given society reflects itself through the fiction. In this sense, the objective of this paper is to reflect upon the Portuguese updated filmic adaptation of The Crime of Father Amaro (1880) by the canonical author Eta de Queiroz. On one hand, the author intends to rethink about the Portuguese identity portrayed by the film and, at the same time, the author manages to observe how the Portuguese society is revealed. On the other hand, the paper aims to analyze the particular process of the adaptation of The Crime of Father Amaro following a qualitative methodology展开更多

However, due to the high complexity of spatial data mining, the need for spatial relationship comprehension and its characteristics, efforts have been directed towards improving algorithms in order to provide an increase of performance and quality of results. Likewise, several issues have been addressed to spatial data mining, including environmental management, which is the focus of this paper. The main original contribution of this work is the demonstration of spatial data mining using a novel algorithm with a multi-relational approach that was applied to a database related to water resource from a certain region of S^o Paulo State, Brazil, and the discussion about obtained results. Some characteristics involving the location of water resources and the profile of who is administering the water exploration were discovered and discussed.展开更多

Since then, teachers have had a lot of work to be done. Every year they have to prepare an individualized programme for each child with special needs. They have to set goals that each child with special needs has to achieve at a particular subject. Pupils have different teachers every year and to make their work easier, the author is considering making a website database with basic information about them. This database would state the goals that the pupil achieved in the past year, which strategy of teaching proved to be the best for him or her and what the areas he or she needs help with are. Teachers would be collecting this data during the primary education, after the final evaluation this database would also be made available to the secondary school of the pupil in concern. This database should be located on the website of Ministry of Education, Science, Culture and Sports. It would be available to primary schools, but protected by a password which would grant the school access to the data of their students only. In secondary schools, teachers could also access to the information, so they would not have to be discovering appropriate teaching strategies that worked for a pupil in the past all over again. This would enable better conditions and a successful education for pupils with special needs.展开更多

Constructing a scientific, environmental-friendly and energy-saving medium-term genebank is essential for preserving crop germplasm resources. However, the construction of medium-term genebank involves a wide range of subjects but lacks unified standard, which might result in many difficulties in the process of construction and application. According to the key parameters of refrigeration system for medium-term genebank, the cooling load was calculated and key system schemes were determined in this paper. Based on the calculation results and designed schemes, the equipment selection was discussed and the standards for construction of bank and monitoring system were proposed with the aim to provide references for germplasm genebank design and equipment selection.展开更多

Since that time, socio economic development in Miyun Area has been slowing due to the restriction of severe environmental standards. More and more attention from the public and government has been paid to the regional sustainable development. And an effective planning for the local society management system is urgently desired. In this study, a regional sustainable development system dynamics model, named MiyunSD, is developed for supporting this planning task. MiyunSD consists of dynamic simulation models that explicitly consider information feedback that governs interactions in the system. Such models are capable of simulating the system′s behavior and predicting its developing situation of the future. For the study case, interactions among a number of system components within a time frame of fifteen years are examined dynamically. Three planning alternatives are carefully considered. The base run is based on an assumption that the existing pattern of human activities will prevail in the entire planning horizon, and the other alternatives are based on previous and present planning studies. The different alternatives will get different system′s environmental and socio economic results. Through analyzing these dynamic results, local authorities may find an optimal way to realize the objectives that the regional environment will be well protected and at the same time the economy will be rapidly developed.展开更多
