Methods: Focus groups were conducted with adult participants (n = 54) to determine attitudes, self-efficacy, and behaviors related to liking and usage of vegetables, herbs and spices as well as strategies to increase vegetable intake. Results: Seasonal availability, and family-centered memories and practices were motivation for vegetable intake. A diverse number of vegetables (n = 39) were listed as favorites based on taste and versatility, but seasonings were not commonly included in responses regarding preparation. Participants felt that vegetable dish names should reflect ingredients explicitly;that seasonings enhanced vegetable flavors;and that salt and pepper were most commonly used seasonings. The preferred strategy to increase vegetable consumption was through tasting or sampling opportunities;seasoning use was not mentioned. However, participants perceived that suggestions or demonstrations on how to prepare vegetables at home would be helpful. Personal gardens were mentioned frequently, but were not connected to strategies for increasing intake. Conclusions and Implications: Vegetable intake has a family focus that should be emphasized to increase intake. Efforts to increase intake could emphasize flavor and versatile preparation methods through tasting opportunities or educational demonstrations.展开更多
针对传统方剂配伍规律分析方法的不足,提出一种面向复杂网络的新型中药(traditional Chinese medicine,TCM)方剂配伍规律挖掘算法。根据中药方剂特性并结合点式互信息构建TCM网络模型,结合TCM网络的小世界特性提出TCM网络的局部适应度模...针对传统方剂配伍规律分析方法的不足,提出一种面向复杂网络的新型中药(traditional Chinese medicine,TCM)方剂配伍规律挖掘算法。根据中药方剂特性并结合点式互信息构建TCM网络模型,结合TCM网络的小世界特性提出TCM网络的局部适应度模型,分析TCM网络的特性并挖掘TCM网络中配伍关系紧密、相似度较大的药物群。以4 000余首经典方剂作为实验对象,验证了所提方法具有较好的有效性,与经典LFM(local fitness measure)算法对比,平均模块度值提高了0.05,为中药方剂的配伍规律进行探索及新药研发提供了新思路。展开更多
