Harmonizing the relationship between urbanization and eco-environment is not only an important proposition for the national development plan but also the only way to promote healthy urbanization. Based on an analysis of urbanization process and its relationship with the eco-environment, this article analyzes interactive coercing effects between urbanization and eco-environment from three perspectives of population urbanization, economic urbanization and spatial urbanization, respectively, and analyzes risk effects of the interactive coercion. Further, it shows six basic laws followed by interactive coercion between urbanization and eco-environment, namely, coupling fission law, dynamic hierarchy law, stochastic fluctuation law, non-linear synergetic law, threshold value law and forewarning law, and divides the interactive coercing process into five stages, namely, low-level coordinate, antagonistic, break-in, ameliorative and high-grade coordinate. Based on the geometric derivation, the interactive coercing relationship between urbanization and eco-environment is judged to be non-linear and it can be explained by a double-exponential function formed by the combination of power and exponential functions. Then, the evolutionary types of the interactive coercing relationship are divided into nine ones: rudimentary coordinating, ecology-dominated, synchronal coordinating, urbanization lagging, stepwise break-in, exorbitant urbanization, fragile ecology, rudimentary break-in and unsustainable types. Finally, based on an interactive coercion model, the degree of interactive coercion can be examined, and then, an evolutionary cycle can be divided into four phases, namely rudimentary symbiosis, harmonious development, utmost increasing and spiral type rising. The study results offer a scientific decision-making of healthy urbanization for achieving the goal of eco-environment protection and promoting urbanization.展开更多

On the basis of an overlapping generation(OLG) model, this paper introduces the health effects of environmental pollution to systematically discuss the optimal distribution ratio of energy tax revenues in subsidizing household income and emission abatement under given tax rates to reduce the risks of "environment-health-poverty" trap. Our research shows that an optimal distribution ratio for maximizing per capita output or an optimal distribution ratio for maximizing public welfare exists. Based on China's actual parameters, however, this study has found that China's energy tax revenue distribution policy hardly meets the two optimal targets at the same time. Specific distribution ratio is subject to government decision-making preference, and needs to be adjusted according to actual differences.展开更多

Several studies showed that health care meant to improve people＇s health is an important source of disease. Good clinical practices aim to maximize effectiveness and therapeutic compliance, minimize risks and costs, respecting the patient＇s choice from generic drugs, also from the moment of prescribing, the supervision of drug-related events must be taken into account, not only on the patient but also in the environment. Pharmacovigilance and pharmacoecovigilance have to be conceived as a clinical practice in dentistry. There is no established culture of drug induced reaction reports by dentists in Uruguay, and awareness of environmental care is incipient. The pharmacy of faculty of dentistry, （Universidad de la Repfiblica）, an institutional project that has been developed since 2006, is in a transformation process. The pharmacovigilance dentistry Node is in full development. The toxicovigilance and pharmacoecovigilance activities are recent. The general aim of this project was to establish the pbarmacovigilance, toxicovigilance and pharmacoecovigilance clinical practice in dentistry. The widespread use of cosmetic as toothpastes, or mouth rinses, drugs and dental materials, as well as exposure to chemical contaminants through the population＇s living habits and the environmental damage caused by drug wastes requires comprehensive and up-to-date information to establish rational strategies.展开更多

It is necessary to compare urban public health status among different cities, so that each city can define its own health patterns and limiting factors. The following assessment indicators were established to evaluate urban public health status： living conditions, physical health, education and culture, envir- onmental quality, and social security. A weighted-sum model was used in combination with these indicators to compare the urban public health status in four cities-- Beijing, New York, London, and Tokyo--using data for 2000-2009. Although the urban public health level of Beijing was lower than that of the other cities, it showed the greatest increase in this level over the study period. Different patterns of urban public health were identified： London had the most balanced, steady pattern （almost all factors performed well and developed stably）; New York and Tokyo showed balanced, but unsteady patterns （most factors remained high, though social security and environ- mental quality fluctuated）; Beijing had the most unba- lanced, unsteady pattern （the different factors were at different levels, and education and culture and social security fluctuated）. For enhanced urban public health status, environmental quality and education and culture clearly need to be improved in Beijing. This study demonstrates that a comparison of different cities is helpful in identifying limiting factors for urban public health and providing an orientation for future urban development.展开更多
