Between 1987 and 1989 there were approximately 5,000 cases of fatal and injury-sustained road traffic accidents, of which 2.3-3.0% were alcohol related (blood alcohol levels greater than the legal limit of 80 mg% ethanol). The offenders of alcohol-related accidents are mostly Chinese (> 79%), male (> 98%), and more often 30-40 years old. The majority of the alcohol-related accidents (> 74%) took place between 8 P.M. and 4 A.M. in fine weather and light traffic. Rear-end, head-on, and side-on collisions comprised > 60% of all the alcohol-related accidents, and losing control of vehicles approximately 30%. Drunken driving cases for the same period that were not accidents showed a number of characteristics similar to those for accidents. In Singapore, motorcycle riders and pedestrians are more prone to road fatality than other road-user groups. International comparisons of road fatalities per 100,000 population gave Singapore one of the lowest accident rates (8.1-8.4) as compared with countries such as Australia, the United Kingdom, the United States, New Zealand, Canada, and Japan. 相似文献

Allele frequencies for the 13 CODIS STR loci included in the AmpFISTR Profiler Plus and AmpFISTR Cofiler kits (Applied Biosystems, Foster City, USA) were determined in a sample of 209 unrelated Chinese in Singapore. The combined random match probability for the 13 loci is about 6.6 x10(-15) and the overall probability of excluding paternity is 0.9999899. The results demonstrate that the loci are useful for forensic human identification and parentage testing for the Chinese population in Singapore. 相似文献

In the early eighties, in response to increasing self-poisoning incidents by pharmaceuticals in Singapore, a comprehensive wide-sweep screen for these drugs in clinical gastric aspirates was devised and implemented by us. The toxicological screen which involved quadruplicate extractions, two in acidic conditions and the other two in alkaline conditions, required the following analyses to be carried out: UV on the acidic fraction, TLC on the basic fraction and mega-bore capillary GC/NPD (nitrogen phosphorus detector) on the combined fraction. The combined fraction if necessary was subjected to GC/MS analysis. Our screen satisfied the need to confirm the analytical outcome of one method by another. Combining the acidic and basic fractions for a single GC analysis saves on instrument time and manpower. All coma and emergency cases were required to undergo GC/MS analysis to prove the identity of toxic agents beyond reasonable doubt. Quality control procedures were instituted at key steps to ensure quality of analytical outcome. 相似文献

In this study of 212 unrelated Singapore Chinese males, allelic frequencies and gene diversities of 11 Y-chromosome specific STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS438 and DYS439) were established. A total of 184 haplotypes were observed in the 212 individuals studied, of which 165 (89.67%) were unique. The most common haplotype was observed in five (2.35%) individuals. The overall haplotype diversity for the 11 Y-STR loci was 99.81%, and the discrimination capacity was 86.79%. 相似文献

Allele frequencies for the 13 CODIS (Combined DNA Index System, USA) STR loci included in the AmpFISTR Profiler Plus and AmpFISTR Cofiler kits (Applied Biosystems, Foster City, USA) were determined in a sample of 197 unrelated Malays in Singapore. 相似文献
