abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
Air pollution causes severe physical and psychological health complications. Considering China's continuously-deteriorating air quality, this study aimed to assess the self-reported effects of air pollution on the behavior and physical health of the students of 13 densely populated cities, and their awareness, practices, and perception of air pollution and its associated public health risks. A ...
Environmental monitoring is required to understand the effects of various kinds of phenomena such as a flood, a typhoon, or a forest fire. To detect the environmental conditions in remote places, monitoring applications employ the sensor networks to detect conditions, context models to understand phenomena, and computing technology to process the large volumes of data. In this paper, we present...
Acidic deposition derived from sulphur and nitrogen pollution can cause many environmental problems which, until recently, were considered to be confined to Europe and North America. It is now clear that regional air pollution is a serious and growing problem in many parts of the World, particularly in certain developing countries. European and North American countries have now committed themse...
The air environmental pollutants exhausted by China have attracted the attention from the world, especially the neighboring countries including Japan. Japan has put forward a conceived model named Air Pollution Prevention Alliance between Japan and China. This article analyzes the background and causations of air environmental pollution problems in China, and the efforts that Chinese government...
In the paper the problem of the real-time emission control is discussed, where the air quality forecast is based on the regional-scale model of air pollution transport. The problem formulation utilizes the optimal control technique for distributed parameter systems, which is integrated with the governing equations of air pollution dispersion process. The approach presented in the paper is sulfu...
OBJECTIVES Air pollution contributes to mortality and morbidity. We estimated the impact of outdoor air pollution on public health in Seoul metropolitan area, Korea. Attributable cases of morbidity and mortality were estimated. METHODS Epidemiology-based exposure-response functions for a 10 μg/m3 increase in particulate matter (PM2.5 and PM10) were used to quantify the effects of air pollutio...
Introduction: One of the main challenges in the field of health economics is detecting the factors affecting on health costs. One of the these factors is air pollution, which has been ignored in most of empirical studies; while air pollution is one of the environmental problems which in recent years has become a serious threat to human health. Therefore, the aim of this study was to evaluate th...
what is called the problems of tehran metropolis now a days, is deep- rooted in the policies ofurban planning in our country. since not far past up to now, immigration from all over the country to tehran, irregular growth of urban population, inconsistency with urban infrastructure development, environmental pollution and low quality of living areas, erosion of self -growing fabric in most area...
This article addresses the development of data linkage methods for the analysis of urban environmental health problems and the development of appropriate policies and discusses, based on existing experience of data linkage in São Paulo (Brazil), the potential for routine environmental health monitoring and management in a major developing country industrial centre. The article looks briefly at ...
