This approach has some distinct disadvantages: 1) GCM must be downscaled; 2) different GCMs are difficult to be reconciled for a given climate change scenario;3) the uncertainty of GCMs is far from the requirement of the evaluation of climate change impacts. To overcome these limits of the traditional method,a new method termed as "bottom-up"was used for climate risk assessment that linked vulnerability assessment with climate information to assess the risk of climate change impacts on the Quabbin Reservoir,and United States under A2 scenario.The result shows that the risks are around 20% in 2006-2035 and 2036-2055,50% in 2066-2095.展开更多

Because of the limited resources allocated to health, it is very important for countries to conduct studies especially on cost of diseases such as colorectal cancer (CRC) with a high burden of disease and labor loss. The aim of this study was to calculate the cost of treatment for colon and rectal cancers based on two different cost approaches from the perspective of SSI (top-down and bottom-up) and to compare the results obtained. <strong>Materials and Methods:</strong> Data were obtained from the SSI MEDULA System a total of 62,970 colon and rectal cancer patient for the top-down cost approach. In the bottom-up cost approach, treatment costs were determined based on the expert opinions. <strong>Results:</strong> The average cost of treatment per patient for colon cancer was determined as 3055.5 TL, for rectal cancer was determined as 4146.2 TL with the top-down cost approach. The average cost of treatment per patient for colon cancer was determined as 14,920.4 TL, for rectal cancer was determined as 17,904.6 TL according to the bottom-up cost approach. <strong>Conclusion: </strong>Since the bottom-up cost approach provides more detailed information on the cost of illness, and thereby on the use of resources allocated to health, it is thought that the combined use of these two cost approaches completes each other’s weaknesses.展开更多
