Mathematical modelling of the growth processes in the developing chick wing bud

This paper illustrates how a simple geometric model resembling the shape of the chick wing bud at an early growth stage can be mathematically expanded to simulate subsequent growth characteristics of the developing bud. The model was tested against several sets of experimental data and gave an acceptable representation of growth over the range considered. Representing growth patterns in this form enables the determination of differential growth characteristics in different parts of the bud and provides boundary constraints which will play an important part in the eventual evaluation of internal growth mechanisms.     

高级综合模拟人联合以问题为基础的教学法进行心肺复苏教学的研究

目的 评价高级综合模拟人(ECS)联合以问题为基础的教学法(PBL)进行心肺复苏英语教学的效果,探讨现代麻醉学英语模拟教学的新方法.方法 42名学生分为对照组及ECS组.以人工呼吸、胸外按压单项操作成绩及对学生反馈意见调查表进行统计学分析,评估教学效果.结果 ECS组与对照组单项操作成绩差异无统计学意义(P＞0.05);ECS组在增强急救意识、提高急救能力等与对照组差异有统计学意义(P＜0.05);86%以上学生认为ECS组教学与对照组差别较大.结论 采用ECS联合PBL进行麻醉学中心肺复苏英语教学,使医学生直接参与"急救工作",处理"各类问题",在实践中增强急救意识和提高急救能力,能够显著提高教学质量,适应现代医学发展的需要.

不规则对象的造型与分析

本文根据不规则对象轮廓的曲率变化以及局部形心位置,提出一套建立三维模型的数学方法,为设计与分析该对象奠定良好的基础。本文已将此方法应用于医学领域的临床工程上,成功地进行了人体中最复杂的硬组织之一,全牙列下颌骨的三维实体造型与力学分析,同时也为在其他领域形状复杂对象的设计与分析提供了一条思路。     

Comparative evaluation among different materials to replace soft tissue in oral radiology studies

Objective

The aim of this study was to establish which materials afford better simulation of soft tissues in Oral Radiology studies.

Material and Methods

The sample was composed of four materials in eleven different thicknesses to simulate the soft tissues of the face. The mean values of the relative amounts of radiographic contrast of the materials were determined and compared to a gold standard value, which was obtained from 20 patients who were referred to have periapical radiographs taken of the left mandibular molars. Data were subjected to statistical analysis with Dunnett''s test (p<0.05).

Results

The mean value of the relative amounts of contrast encountered in the patients was 0.47, with a range between 0.36 and 0.64 for all 44 material/thickness combinations. The majority of the tested materials showed values close to those of the patients’ tissues, without statistically significant differences among them. The values of only three materials/ thickness combinations differed statistically from those of the patients’ tissues.

Conclusions

Based on the results of the present study, it may be concluded that except for utility wax (4 mm and 8 mm) and water (4 mm), all materials tested at different thickness could be used as soft tissue substitute materials in Oral Radiology studies.
