Using a 3D food printer as a teaching tool: Focus groups with dietitians,teachers, and nutrition students

Three‐dimensional (3D) food printing is a new technology that can be used to produce personalized and customized food products. However, very little research has been completed on how 3D food printers could be used as educational tools. As such, the objective of this study was to evaluate how teachers (n = 6), dietitians (n = 6), and nutrition students (n = 11) envision the use of 3D food printers when disseminating information about food and nutrition. Focus groups were conducted with teachers, dietitians, and nutrition students. Initially, the participants were introduced to the concept of 3D food printing and then they were asked how they could use a 3D food printer in their teachings. The participants did not feel that a 3D food printer would enhance their teaching and instead felt it could confuse or frighten people. Also, all of the participants were worried about learning how to 3D print foods. The participants did state that people would be interested in watching a 3D food printer. Furthermore, the teachers and nutrition students indicated they thought a demonstration of a 3D food printer would lead to more interest in food and nutrition. Additionally, they thought a 3D food printer could be used to create visually appealing foods. Overall, until 3D food printers are found in residential and commercial kitchens, the participants did not think it would enhance their teachings; however, they did indicate that 3D food printing demonstrations could lead to students being interested in the food and nutrition fields.     

对扁平足的体育康复探讨

通过查阅大量有关儿童少年扁平足发病率和康复方法的文献和资料，从而得知扁平足发病率高，手术治疗弊病多。远期疗效不理想等目前无法克服的矛盾。进而提出了用推拿和体育康复训练相结合的手段来康复扁平足的论点。经过典型病例实验研究，与多学科的学术理论分析，最后得出推拿与体育康复训练相结合的康复手段是防治扁平足的科学有效手段，有利于推广和普及。

The Press,Paper Shortages,and Revolution in Early America

The printing press helped to spread literacy, civic discourse, and even political dissent in colonial America. Without paper, however, the invention of the moveable type printing press would have been insignificant. This crucial communication medium was hobbled by a critical shortage of the raw material needed for printed matter. Paper was in short supply in the colonies and in the new nation as it could only be made from rags, and there was constant difficulty in obtaining enough rags to keep the presses rolling. Pleas for this essential ingredient were constantly seen in the newspapers in early America and there were severe shortages of both paper and the rags from which it was made during the American Revolution. This article examines how desperate were the early Americans for the paper which was necessary both for firing the muskets and for spreading the rhetoric of Revolution.     

Does Augmented Visual Feedback from Novel,Multicolored, Three-Dimensional-Printed Teeth Affect Dental Students' Acquisition of Manual Skills?

Although three-dimensional (3D) printing technology is increasingly used in dental education, its application regarding the provision of online visual augmented feedback has not been tested. Thus, this study aimed to: (1) develop two generations of multicolored 3D-printed teeth that provide visual augmented feedback for students conducting the cavity preparation process, (2) assess students' clinical performance after training on the 3D models, and (3) acquire student feedback. For the first-generation model, augmented feedback was obtained from five 3D-printed teeth models for five cavity preparation procedures. Each model comprised three layers printed in green, yellow, and red indicating whether preparation was acceptable, limited, or unacceptable, respectively. The study used a crossover design in which the experimental group trained on five multicolored models and 10 standard plastic teeth, and the control group trained on 15 standard plastic teeth. Students gave positive feedback of the methodology but complained about the printed material's hardness. Therefore, a second-generation model was developed: the model's occlusal plane was replaced with a harder printed acrylic material, and the experiment was repeated. During training, instructors provided external terminal feedback only for performance on standard plastic teeth. Manual grades for cavity preparations on standard plastic teeth were compared. No significant differences were found between the control and experimental groups in both generations' models. However, less instructor time was needed, and similar clinical results were obtained after training with both generations. Thus, multicolored 3D-printed teeth models promote self-learning during the process of acquiring manual skills and reduce student dependency on instructors.
