目的比较TW2法英国人标准、TW2法中国人南方标准和TW3法测定腕骨骨龄对特发性性早熟(IPP)女孩的诊断价值。方法女性IPP患儿55例;对照组83例。回顾性分析初诊左腕X线片,用TW2法、TW2CHC中国人南方标准和TW3法盲法分期,分别测得其腕骨骨龄及其百分位,并分为5个连续性的工作点,即:>P97、>P90、>P75、>P50和、≤P50。结果敏感度(Sen)和特异度(Spe)都比较高的有以下3个工作点:TW2CH“>P90”点,TW3“>P90”点,TW2“>P90”点。结论TW系统3种腕骨骨龄对于IPP女孩都有诊断价值,TW3法和TW2法中国人南方标准诊断价值比较高,TW2法英国人标准的诊断价值为中等。 相似文献

日本护理保险制度制定的原因分析及启示 总被引:4,自引:0,他引:4
战后,面对快速到来的老龄化社会,日本政府在社会保险方面采取了各种对策,老年护理保险制度经历了从无到有、不断发展完善的过程,其间既有成功经验,又有失败教训。目前,我国的老龄人口护理问题也日益突出,如何建立符合我国国情的老年护理保险体系,日本的做法是具有参考价值的。 相似文献

We use data from a survey covering ages 15–94 to test the Hirschi/Gottfredson hypothesis that the correlates and causes of crime do not interact with age. These data reveal some nonchance interaction between age and demographic and theoretical predictors of criminal behavior that is localized in specific age categories and around particular variables and/or offenses. Overall, however, such interaction does not appear to be substantial, nor does it seem to have important consequences for generalizing from age restricted samples, particularly where generalization is of the most common type-from youth samples to adults. Therefore, despite some results contrary to a strict assertion that the causes and correlates of crime are the same for all ages, our findings support the thrust of the Hirschi/Gottfredson interaction hypothesis. 相似文献

This article investigated the moderating role of age on the positive relationship between computer self-efficacy (CSE) and intention to use e-government services.The Technology Acceptance Model was used as the theoretical framework for this study while the data was analyzed with SPSS. The results showed that age as a demographic factor was significant and positively moderates the impact of CSE on the intention to use e-government services. Also, CSE was a significant predictor of the intention to use but age does not have a direct significant impact on the intention to use. The implications of these findings are discussed. 相似文献

Multiple fatality incidents involving more than one child of statistically same age (including twins) can be challenging from an identification standpoint. This case details an urban fire, in which four children perished. Age assessment on three of the victims utilizing maturity staging described by Moorrees, Fanning, and Hunt yielded insignificant results. However, a plot of the MFH data shows the difference between two identical twins and a third child. The twins share a similar growth pattern, whereas the other was different. Based on this graphical interpretation, the nontwin victim was positively identified through exclusion. These results were verified through statistical testing. This case demonstrates a method to repurpose age assessment data to graphically distinguish between child victims. Further, it is shown that radiographic and clinical presentation in childhood identical twins can elicit genetic versus acquired similarities and differences, which can be used for identification of individuals and exclusion of others. 相似文献

This study investigated the relationship between chronological age and pulp tooth area ratio (PTR) in maxillary central teeth using cone‐beam computed tomography (CBCT) images in the Turkish population. The sample consisted of CBCT images of 120 male and female subjects between 14 and 75 years old. The PTR of the maxillary central teeth was calculated using inVivo 5 software (Anatomage, San Jose, CA). Data were analyzed with independent t‐test and Pearson's rank correlation test. There was a significant negative correlation between chronological age and PTR (r = ?0.615). The results showed that the PTR of maxillary central teeth is a reliable method for age estimation in the Turkish population. 相似文献
