In recent decades, three-dimensional (3D) printing as an emerging technology, has been utilized for imparting human anatomy knowledge. However, most 3D printed models are rigid anatomical replicas that are unable to represent dynamic spatial relationships between different anatomical structures. In this study, the data obtained from a computed tomography (CT) scan of a normal knee joint were used to design and fabricate a functional knee joint simulator for anatomical education. Utility of the 3D printed simulator was evaluated in comparison with traditional didactic learning in first-year medical students (n = 35), so as to understand how the functional 3D simulator could assist in their learning of human anatomy. The outcome measure was a quiz comprising 11 multiple choice questions based on locking and unlocking of the knee joint. Students in the simulation group (mean score = 85.03%, ±SD 10.13%) performed significantly better than those in the didactic learning group, P < 0.05 (mean score = 70.71%, ±SD 15.13%), which was substantiated by large effect size, as shown by a Cohen’s d value of 1.14. In terms of learning outcome, female students who used 3D printed simulators as learning aids achieved greater improvement in their quiz scores as compared to male students in the same group. However, after correcting for the modality of instruction, the sex of the students did not have a significant influence on the learning outcome. This randomized study has demonstrated that the 3D printed simulator is beneficial for anatomical education and can help in enriching students’ learning experience.  相似文献   

Three-Dimensional Printing of Archived Human Fetal Material for Teaching Purposes

The practical aspect of human developmental biology education is often limited to the observation and use of animal models to illustrate developmental anatomy. This is due in part to the difficulty of accessing human embryonic and fetal specimens, and the sensitivity inherent to presenting these specimens as teaching materials. This report presents a new approach using three-dimensional (3D) printed replicas of actual human materials in practical classes, thus allowing for the inclusion of accurate examples of human developmental anatomy in the educational context. A series of 3D prints have been produced from digital data collected by computed tomography (CT) imaging of an archived series of preserved human embryonic and fetal specimens. The final versions of 3D prints have been generated in a range of single or multiple materials to illustrate the progression of human development, including the development of internal anatomy. Furthermore, multiple copies of each replica have been printed for large group teaching. In addition to the educational benefit of examining accurate 3D replicas, this approach lessens the potential for adverse student reaction (due to cultural background or personal experience) to observing actual human embryonic/fetal anatomical specimens, and reduces the potential of damage or loss of original specimens. This approach, in combination with ongoing improvements in the management and analysis of digital data and advances in scanning technology, has enormous potential to allow embryology students access to both local and international collections of human gestational material.

扫叶山房创始年代考   总被引：1，自引：0，他引：1  

杨丽莹 《图书馆杂志》2005,24(3):68-73

目前学术界对清代著名书坊扫叶山房的创始年代有着不同的说法，其中主要代表有明万历说和明季说等。本文通过对各说的辨析，并考察扫叶山房主人洞庭席氏相关人物的情况，以及席氏购藏汲古阁《十七史》书版的经过，从而确定清乾隆后期当为扫叶山房真实的创始年代。  相似文献

基于硅氧烷喷墨打印加工纸芯片的研究     

蔡龙飞  林俊  侯淑如  王婉露  薛燕娜 《韩山师范学院学报》2015,(3)

提出了一种基于硅氧烷喷墨打印技术加工纸芯片的方法。将十八烷基三甲氧基硅烷的正庚烷溶液以喷墨打印的方式打印到滤纸上，由于滤纸的强吸水性，十八烷基三甲氧基硅烷的甲氧基水解生成硅羟基，硅羟基与滤纸纤维上的羟基缩合使硅氧烷结合到滤纸纤维上。该加工方法简单、低廉，适于纸芯片的大规模加工与制作。用该方法加工的纸芯片分析了尿样中的蛋白质含量，证明其在临床检测中的广泛应用前景。  相似文献
