With the support of standard database of master process planning documents which are developed by parameterization technique, and instance process planning for special product(instance product)can be generated automatically by the sub-system of variant de- sign of process planning.Finally,a CAPP system was developed for process design of rotor of steam turbine to validate the feasibil- ity and applicability of the method.展开更多
目的评价“对分课堂”与案例教学联合模式在提升专业型公共卫生硕士(Master of Public Health,MPH)研究生健康干预计划设计能力中的应用效果。方法于2022—2023学年和2023—2024学年春季学期,采用全面调查方法选取北京大学选修健康教育...目的评价“对分课堂”与案例教学联合模式在提升专业型公共卫生硕士(Master of Public Health,MPH)研究生健康干预计划设计能力中的应用效果。方法于2022—2023学年和2023—2024学年春季学期,采用全面调查方法选取北京大学选修健康教育与健康促进课程的所有MPH研究生为研究对象。采用“对分课堂”与案例教学对课程进行改革,采用历史对照单盲试验设计、描述性分析等方法比较MPH研究生健康干预计划设计能力提升效果。结果基于课程分析,本研究提出了加强对健康行为和传播理论价值的思考、健康教育干预计划实践训练以及逻辑实践训练3项改革重点。MPH研究生健康干预计划设计能力提升结果显示,试验组学生的健康干预项目计划书总分为(89.35±3.59)分,高于对照组;评价方案、背景与需求评估、干预策略、行为理论或传播理论维度得分分别为(26.95±0.64)分、(26.90±1.37)分、(26.30±1.60)分、(9.20±0.92)分,均高于对照组。结论“对分课堂”与案例教学联合模式在提升MPH学生健康干预项目设计的整体质量,尤其是评价方案设计方面具有积极作用。因此,可认为该教学模式对于提升MPH研究生健康干预计划设计能力具有一定的积极作用。展开更多
