［Objective］To sum up the experience of wearing the halo pelvic and level traction costoplasty to treat 35 cases of severe scoliosis combined with collapsed chest.［Methods］When scoliosis of patients were corrected to a certain degree after three weeks of halo pelvic distraction, the most serious collapsed ribs of concave side of the curve underwent a transverse incision the cross ribs. A special rib bender was used to bend the exposed 3 to 6 ribs. The bent ribs were pulled up by double-stranded 10# thick silk which was extended out through the skin and fixed in the upright post of the instrument of Halo pelvic distraction with rubber membranes.［Results］Thirty-three in 35 patients underwent costoplasty.

［目的］介绍35例重度脊柱侧弯合并严重胸廓塌陷的病例，在颅盆牵引的过程中，同时采用肋骨成形术加水平牵引治疗胸廓塌陷［方法］颅盆牵引3周后，脊柱侧弯矫正到定程度时，在侧弯凹侧肋骨塌陷最重的部位，与肋骨交叉作横切口，暴露3～6条肋骨，用特制的肋骨折弯器将肋骨折弯变圆，用10号双股粗丝线将每条肋骨提起，自皮肤穿出通过橡皮膜在颅盆装置的立柱上作牵引。

In this paper, fuzzy theory, Markov chain and RFM model are integrated to evaluate customer lifetime values. This approach calculates the profit contribution of customers in every purchasing situation. Firstly, customer purchasing state is updated contiguously by fuzzy theory and RFM model with transition matrix which represents the probabilities among purchasing states. Then the profit contribution of each period is computed by using revenue and cost data. Finally, the profit contribution of each customer is accumulated through some discounting consideration. This will construct the final customer lifetime values.

本研究结合模糊理论、马可夫链、和RFM(recency， frequency， monetary； RFM)模式，配合折现模式来计算顾客终身价值，其中模糊理论及RFM模型定义顾客之购买状态，马可夫链则推算顾客在每期购买状态改变的机率，然后推估出顾客在每期交易的转换机率，再结合产品的收益与成本资料，算出顾客在各期对公司的利润贡献，最后将各期的利润贡献折现加总，计算出各种购买状况下的顾客价值，利用此顾客价值就可指出哪些是对企业有利的顾客。
