THE SHAPE OF THE DISTRIBUTION OF THE NUMBER OF SEXUAL PARTNERS

Information on the number of sexual partners that people have is necessary for predicting the likely long term course of the AIDS epidemic. More information is required than is provided by simply stating the mean and variance of the number of partners. It is useful to find a family of curves which approximate data on the proportion of people in the various ‘number of partners’ categories. Two Australian surveys of the sexual behaviour of first year university behavioural science students were analysed. It was found here that log-normal distributions gave good approximations to the distribution of number of partners amongst people who had more than one partner. Gamma and negative binomial distributions gave less satisfactory fits and the truncated normal and Poisson distributions were clearly unable to match the data.

回归树在分析病例组合住院费用影响因素中的应用

[目的]通过分析病例组合住院费用的影响因素,探讨制定病种定额付费的方法。[方法]利用非参数的回归树,就某医院2005年出院病人的26种病例组合住院费用影响因素进行研究。[结果]住院天、入院情况、预后、抢救次、职业、年龄及性别是影响住院费用的因素,其中最为关键的因素是住院天。[结论]回归树与DRGs系统建模思想一致,可以作为建立病种定额付费的方法。

THE USE OF THE UNEMPLOYED IN THE FIELD OF SANITATION

Unemployment and under employment are topics that the average health officer pays little attention to. No one will deny the significance of unemployment when considered solely from the public health point of view. Men and women who are out of work or who are only working part time necessarily are unable to buy proper food and shelter which are so essential for their physical well being. Mr. McCrudden, in this paper, tells in an interesting manner how a number of unemployed men were given work through the Health Department of the City of Philadelphia. Not only did they benefit themselves but the work they did was a direct benefit to the entire community. This is a subject that health officials generally might well give more attention to.     

气管切开外套管固定带方法改良的临床效果观察

[目的]探讨气管切开后外套管固定带采用改良方法的临床效果。[方法]采用床位单双号将我科行气管切开术后69例患者随机分为观察组﹙36例﹚和对照组﹙33例﹚,对照组按常规使用布带为气管外套管固定带,观察组将布带套上血浆管后再作为气管外套管的固定带。[结果]观察组皮肤损害的发生率较对照组明显降低,观察组皮肤损害程度较对照组轻,观察组损害时间也比对照组明显延缓,差异均有统计学意义(P﹤0.001)。[结论]行气管切开术后使用套有血浆管的气管外套管固定带有效地防止了颈部皮肤的损害,避免了感染,操作简便,耗材低廉,值得推广和应用。
