The indirect channel is captured by a production func-tion in which the principal health-improving factor, income growth, can be realized only in the cost of pollution increase. This model is then tested by the aggregated chronicle disease data in over 78 Chinese counties. Our results show, after attaining the threshold of 8 μg/m2, continuous increase in industrial SO2 emission density will lead the ratio of population suffering chronicle diseases, among which respiratory diseases occupy a significant proportion, to rise. However, owing to technological progress in pollution control activities, the needed SO2 emission to produce one unit of GDP diminishes with time. Therefore, the negative effect from pollution augmentation on public health seems to be recompensed more and more by the positive effect of economic growth.展开更多

Methods: Patients received irinotecan 60 mg/m^2 on days 1, 8, 15, and cisplatin 25 mg/m^2 on days 1-3, every 28 days one cycle. Response was evaluated every two cycles and patients were follow-up for two years or until death. Results: Among the 28 evaluable patients, there were 1 CR, 7 PR, 8 SD and 12 PD. The response rate was 28.6% (8/28). Median time to progression (TTP) was 3.2 (0.8-5.6) months. Median survival after second-line treatment was 7.5 (1.5-31) months and overall survival was 15 (2.3-43.5) months. The most common adverse effect was hematological toxicity with 36.7% (11/30), grades Ⅲ-Ⅳ neutroperia. Hepatic toxicity was another major side effect. Only one patient developed grade Ⅲ diarrhea. Conclusion: The combination of irinotecan and cisplatin is feasible, effective, and safe for SCLC as second-line treatment.展开更多

WTE technologies will burn waste that is fed and utilized energy generated to be converted into electrical energy. This technology has the potential to reduce the volume of waste more effectively, but WTE also emit various harmful contaminants, including Polychlorinated Dibenzofurans (PCDF) and Polychlorinated Dibenzo-p-Dioxins (PCDDs). WTE equipped with air pollution control, so that the emission of harmful contaminants can be controlled and detected continuously. This study only discusses contaminants PCDF and PCDDs, and the effect of air pollution control work against public health risks. In this study, the efficiency of air pollution control is assumed at 0%, 25%, 50%, 75%, 90% and 99%, while the public health risk assessment carried out for the projected 15 years into the future. Public health risk assessment carried out by the calculation of the health risk of carcinogenic (liver cancer). A causal relationship between the independent variable efficiency of air pollution control with one dependent variable number of liver cancer patients, obtained the simple linear regression equation Y = 76.4592 - 0.7692X.展开更多

This quantitative evaluation is numerical modeling of biomaterial of human body. Measurement for rehabilitation and developing numerical modeling in patients are useful for information technology education with healthcare background. The resistive torque and electromyogram were measured. Electromyogram is the neuronal activity from eight lower limb muscles. Both activities are output signals for angle input signals. The resistive torque of a stroke patient shows a hysteresis curve, and this is a velocity-dependent component, particular for stroke. Differentiated angle by muscle spindle, a velocity-dependent component, is a stretch reflex (spasticity). In an electromyogram of a stroke patient, SLR (stretch reflex via spinal cord) means a short latency reflex, and LLR (stretch reflex via cerebral cortex) means a long latency reflex. An example of some stroke electromyogram shows long latency reflex, and this is voluntary movement during the experiment. The example of some stroke resistive torque reveals that viscoelasticity is used for the intrinsic component. The example of some stroke electromyogram reveals that long latency reflex is used for the reflex component of lower limbs. Current research needs improvement. Intrinsic viscoelasticity is modeled by a second-order differential equation. The reflex component of stroke patients is modeled by a double exponential function. Open source software is in use. Information technology-based analyses by numerical modeling would be applied in future healthcare education.展开更多

The focus of this special issue is on current research on the effects of biochar application to soil for overcoming diverse soil constraints and recommending further research relating to biochar application to soil. The biochar research has progressed considerably with important key findings on agronomic benefits, carbon sequestration, greenhouse gas emissions, soil acidity, soil fertility, soil health, soil salinity, etc., but more research is required before definitive recommendations can be made to end-users regarding the effects of biochar application across a range of soils, climates and land management practices.展开更多
