The Use of Augmented Reality Technology in Medical Specimen Museum Tours     

Atsushi Sugiura  Toshihiro Kitama  Masahiro Toyoura  Xiaoyang Mao 《Anatomical sciences education》2019,12(5):561-571

Human anatomical specimen museums are commonly used by medical, nursing, and paramedical students. Through dissection and prosection, the specimens housed in these museums allow students to appreciate the complex relationships of organs and structures in more detail than textbooks could provide. However, it may be difficult for students, particularly novices, to identify the various parts of these anatomical structures without additional explanations from a docent or supplemental illustrations. Recently, augmented reality (AR) has been used in many museum exhibits to display virtual objects in videos captured from the real world. This technology can significantly enhance the learning experience. In this study, three AR-based support systems for tours in medical specimen museums were developed, and their usability and effectiveness for learning were examined. The first system was constructed using an AR marker. This system could display virtual label information for specimens by capturing AR markers using a tablet camera. Individual AR markers were required for all specimens, but their presence in and on the prosected specimens could also be obtrusive. The second system was developed to set the specimen image itself as an image marker, as most specimens were displayed in cross section. Visitors could then obtain the label information presented by AR without any markers intruding on the display or anatomical specimens. The third system was comprised of a head-mounted display combined with a natural click interface. The system could provide visitors with an environment for the natural manipulation of virtual objects with future scalability.  相似文献

中文电子病历的分词及实体识别研究   总被引：1，自引：0，他引：1  

王若佳  赵常煜  王继民 《图书情报工作》2019,63(2):34-42

[目的/意义]健康医疗大数据是我国重要的基础性战略资源，本研究对中文电子病历分词与实体识别的探讨与实证较好地完成了医疗数据的信息抽取任务，对今后医疗大数据在语义层面的应用发展具有重要意义。[方法/过程]本研究首先融合权威词表、官方标准、健康网站数据及其他医学补充词库构建了词语数量级达到10万的医学词表；然后对电子病历的字段进行分词，对比了jieba工具、导入词典后的jieba、无监督学习及AC自动机4种模型的分词效果；最后，以自动分词和人工标注结果为语料，实现基于条件随机场的电子病历实体识别研究，并比较不同实体类别以及不同文本特征下的实体识别效果，选出最优模板。[结果/结论]分词结果显示，AC自动机的效果最好，F值可达82%；实体识别结果表明，"检查"和"疾病"实体的识别效果最好，而"症状"的识别效果不太理想。  相似文献   

The impact of immediate test score reporting on university students' achievement emotions in the context of computer-based multiple-choice exams     

《Learning and Instruction》2017

Test-taking is an emotion-laden event for many students. Typically, negative emotions are highest at the start of an examination and are replaced by positive emotions as the exam progresses. The impact of computer-based testing and immediate score reporting on students' emotions has not been examined. In Study 1, we evaluated university students’ emotions at the end of a computer-based exam and found positive emotions more strongly endorsed than negative. In Study 2, we replicated this finding and used a quasi-experimental pre-post design to examine how emotions changed in response to real examination scores. Exam scores presented immediately had significant positive effects on relief, pride, and hope and negative effects on anxiety and shame even after controlling for the corresponding emotion at the end of the exam. The one exception was anger, which was not impacted by examination score. No interaction effects were found.  相似文献

陈小芒  黄卫兴 《赣南师范学院学报》2002,(5):76-79

悼亡文学是祭悼活动发展到一定阶段的产物 ,其起源与发展从一开始就受社会文化、民族心理、地理环境等因素的影响和制约。悼亡作品中创作主体的情感通常表现为一定的模式 ,这些情感模式展示了传统的爱情观 ,特别是对失落的爱情的态度。而悼亡作品的价值取向又表现了传统的爱情价值观和自我价值观的统一。悼亡作品中独特的情感表达模式和价值取向共同构建起了悼亡文学有别于其它文学的个性特征  相似文献

情感教育的内容是道德感、理智感和审美感教育。建立中小学情感教育操作性目标、内容、方法体系等，是中小学实施情感教育的基础。实验表明，开展情感教育对中小学生情感及认知能力的发展有着重要作用。教师情感素质是以教育爱为核心成份的教育价值观、思维方式、行为艺术以及教育风格等因素组成的综合体，培养教师情感性素质的基本途径是建立职前职后一体化的培养体制。  相似文献   

基于条件随机场的学术期刊中理论的自动识别方法     

陈锋  翟羽佳  王芳 《图书情报工作》2016,60(2):122-128

[目的/意义]从学术期刊中抽取其中的理论是对文献进行内容分析的前提,实现理论名称识别的自动化可以提高内容分析的效率。[方法/过程]将理论识别视为一类命名实体识别问题,总结现有的命名实体识别的常用方法,提出一个基于语义泛化思想的命名实体识别方法,选取词性、知网义原等外部知识,采用CRF模型对《情报学报》1822篇论文的标题和摘要进行实验。[结果/结论]实验表明,识别准确率最高达到95.38%,但召回率较低;训练语料规模对性能影响较大,不同程度的语义泛化方法对准确率和召回率有复杂影响。如何选择语义特征、语义标注和语义消歧是需要解决的新问题。  相似文献
