Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.  相似文献

The study examined whether an academic, social, or both an academic and social focus might relate with achievement goals and academic achievement. Participants were 412 urban elementary school students. Results suggest that students with an academic focus toward school have more mastery‐approach and less mastery‐avoid achievement goals. Academic achievement (standardized test scores) did not relate with boys’ or girls’ focus toward school. These findings suggest that academic motivation, but not achievement, correspond with self‐perceptions of school as being a place to learn or school as a place for social interactions.  相似文献

Software vulnerability due to practical drift     

Christian V. Lundestad  Anique Hommels 《Ethics and Information Technology》2007,9(2):89-100

The proliferation of information and communication technologies (ICTs) into all aspects of life poses unique ethical challenges as our modern societies become increasingly dependent on the flawless operation of these technologies. As we increasingly entrust our privacy, our well-being and our lives to an ever greater number of computers we need to look more closely at the risks and ethical implications of these developments. By emphasising the vulnerability of software and the practice of professional software developers, we want to make clear the ethical aspects of producing potentially flawed software. This paper outlines some of the vulnerabilities associated with software systems and identifies a number of social and organisational factors affecting software developers and contributing to these vulnerabilities. Scott A. Snook’s theory of practical drift is used as the basis for our analysis. We show that this theory, originally developed to explain the failure of a military organisation, can be used to understand how professional software developers “drift away” from procedures and processes designed to ensure quality and prevent software vulnerability. Based on interviews with software developers in two Norwegian companies we identify two areas where social factors compel software developers to drift away from a global set of rules constituting software development processes and methods. Issues of pleasure and control and difference in mental models contribute to an uncoupling from established practices designed to guarantee the reliability of software and thus diminish its vulnerability.  相似文献
