Then, interannual and interdecadal characteristics of the SCS summer monsoon onset are analyzed. In addition, we calculate air-sea heat fluxes over the Indian Ocean using the advanced method of CORARE3.0, based on satellite remote sensing data. The onset variation cycle has remarkable interdecadal variability with cycles of 16 a and 28 a. Correlation analysis between air-sea heat fluxes in the Indian Ocean and the SCS summer monsoon indicates that there is a remarkable lag correlation between them. This result has important implications for prediction of the SCS summer monsoon, and provides a scientific basis for further study of the onset process of this monsoon and its prediction. Based on these results, a linear regression equation is obtained to predict the onset date of the monsoon in 2011 and 2012. The forecast is that the onset date of 2011 will be normal or 1 pentad earlier than the normal year, while the onset date in 2012 will be 1-2 pentads later.展开更多

Methods: This crosssectional study was conducted in Fats Province of Iran during a 29month period from March 2009 to July 2011. The data were from the Fats Forensic Medi cine Registry, In 4 923 recorded road traffic accident fatalities, 971 deaths were due to pedestrian accidents. The demographic and accidentrelated information were analyzed by SPSS ver sion 11.5. P value less than 0.05 was considered significant. Results: The mean age of decedents was (47.2±26.2) years, ranging from 6 months to 103 years old. Males ac counted for 69.8% of all deaths. Fatal accidents were mostcommon in September; 56.1% of the fatal injuries occurred on intracity roads and 33.1% on extracity roads. Fatal head injuries were present in 60.54% of cases. Evaluation of the injury site and the cause of death found that they were significantly associated with age, interval between injury and death. Besides, the type of roads played an important role in mortality. Conclusion: Although the clinical management of trauma patients has been improved in our country in the recent decade, decreasing the burden of injuries needs co ordination among trauma system organizations.展开更多
