Automatic testing and assessment of neuroanatomy using a digital brain atlas: Method and development of computer‐ and mobile‐based applications

Preparation of tests and student's assessment by the instructor are time consuming. We address these two tasks in neuroanatomy education by employing a digital media application with a three‐dimensional (3D), interactive, fully segmented, and labeled brain atlas. The anatomical and vascular models in the atlas are linked to Terminologia Anatomica. Because the cerebral models are fully segmented and labeled, our approach enables automatic and random atlas‐derived generation of questions to test location and naming of cerebral structures. This is done in four steps: test individualization by the instructor, test taking by the students at their convenience, automatic student assessment by the application, and communication of the individual assessment to the instructor. A computer‐based application with an interactive 3D atlas and a preliminary mobile‐based application were developed to realize this approach. The application works in two test modes: instructor and student. In the instructor mode, the instructor customizes the test by setting the scope of testing and student performance criteria, which takes a few seconds. In the student mode, the student is tested and automatically assessed. Self‐testing is also feasible at any time and pace. Our approach is automatic both with respect to test generation and student assessment. It is also objective, rapid, and customizable. We believe that this approach is novel from computer‐based, mobile‐based, and atlas‐assisted standpoints. Anat Sci Educ 2:244–252, 2009. © 2009 American Association of Anatomists.     

计算机绘制连杆运动轨迹图谱的方法

本推导出了四杆机构中连杆上任意一点的坐标方程，用常用的应用软件Excel计算出该点在运动过程中的一系列坐标值，并采用Excel中的“插入图表”功能自动绘出了连杆运动轨迹图谱，为设计在按连杆运动轨迹设计四杆机构时提供了一个准确、简捷且非常实用的工具。

Immersive Anatomy Atlas: Learning Factual Medical Knowledge in a Virtual Reality Environment

In order to improve learning efficiency and memory retention in medical teaching, furthering active learning seems to be an effective alternative to classical teaching. One option to make active exploration of the subject matter possible is the use of virtual reality (VR) technology. The authors developed an immersive anatomy atlas which allows users to explore human anatomical structures interactively through virtual dissection. Thirty-two senior-class students from two German high schools with no prior formal medical training were separated into two groups and tasked with answering an anatomical questionnaire. One group used traditional anatomical textbooks and the other used the immersive virtual reality atlas. The time needed to answer the questions was measured. Several weeks later, the participants answered a similar questionnaire with different anatomical questions in order to test memory retention. The VR group took significantly less time to answer the questionnaire, and participants from the VR group had significantly better results over both tests. Based on the results of this study, VR learning seems to be more efficient and to have better long-term effects for the study of anatomy. The reason for that could lie in the VR environment's high immersion, and the possibility to freely and interactively explore a realistic representation of human anatomy. Immersive VR technology offers many possibilities for medical teaching and training, especially as a support for cadaver dissection courses.

基于16G101平法图集钢筋工程量计算问题的研究

在实际工作中,常会出现对于同一工程同样的图纸,不同人计算出的钢筋量不同甚至差别很大,这给工程施工、预决算都带来很大的困惑。文章将以常用钢筋混凝土构件为例,以16G101平法图集为依据,分析钢筋量计算要点,为建筑相关各方在钢筋量计算方面消除分歧,同时,也为确定钢筋量计算规则提供依据。     

中外运动康复专业发展动态的可视化分析

为探索运动康复专业人才培养的热点及前沿问题,对中外运动康复专业人才培养机构、研究动态进行可视化研究,以Web of Science^tm和CNKI数据库为数据源,运用CiteSpace 5.0软件对运动康复专业人才培养模式进行可视化分析,了解其时空分布、历史脉络。研究结果表明:(1)加拿大、美国、英格兰等国在运动康复研究中具有一定的基础性与先进性,研究机构呈现协同合作现象和突增性;研究重点为康复专业学生在团队合作中的专业角色和有效沟通能力,残疾人长期康复、康复专业学生的跨专业学习、综合护理能力。(2)我国目前关于运动康复专业的发展主要集中于专业的建设和课程体系的发展,对就业去向的探讨;作者和合作机构的合作较少,定量研究较少。通过寻找我国与国外运动康复专业人才培养模式的不同,以期为今后的人才培养模式提供新思路。     

二维Otsu算法在壁虎脑切片图像处理中的应用

提出将基于二维Otsu算法的分割方法应用于大壁虎脑切片彩色图像背景区域的漂白处理中及保护目标区域的方法,并对一维和二维算法进行了比较。首先构建二维直方图,然后利用二维直方图建立二维Otsu算法,并对大壁虎脑切片彩色图像进行分割,最后恢复分割完成的二值图像中目标区域的彩色特性。这一方法在生物医学彩色图像处理中得到了较好的实现,同时,本文进一步验证了该方法在普通彩色图像处理中的可行性。
