[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   

Virtual Microscopy as a Learning Tool in Brazilian Medical Education

Virtual microscopy (VM) is a widely used teaching method in Medical Education in many developed countries. In Brazil, however, this is not the case for most medical schools, considering Brazilian social inequality and uneven access to technology. Recently, the Covid-19 pandemic has also challenged Universities to seek and make a transition toward more effective methods of full-time online education. Thus, the main goal of this work was to verify student's perception and academic performance, assessed upon VM implementation in a Brazilian Medical School. Ribeirao Preto Medical School students answered a 26-question survey with regards to optical microscopy (OM) and VM. Academic performance was compared between participants that were (year of 2019) or were not (year of 2015) exposed to VM. Taken the results together, subjective impressions such as handling, suitability, learning effectiveness, and pleasure using the tools, have shown a higher score for virtual microscopy (median = 29), when compared to optical microscopy (median = 24) with a P-value < 0.001 by Wilcoxon rank test, upon measurement using an ordinal scale. Regarding academic performance, no statistically significant differences were found between groups (P-value = 0.38, Cohen's d = 0.19). Therefore, VM proved to be adequate to the Brazilian medical education in light of Brazilian social contexts and Covid-19 pandemic.  相似文献   

Strength,Weakness, Opportunity,Threat (SWOT) Analysis of the Adaptations to Anatomical Education in the United Kingdom and Republic of Ireland in Response to the Covid-19 Pandemic

The Covid-19 pandemic has driven the fastest changes to higher education across the globe, necessitated by social distancing measures preventing face-to-face teaching. This has led to an almost immediate switch to distance learning by higher education institutions. Anatomy faces some unique challenges. Intrinsically, anatomy is a three-dimensional subject that requires a sound understanding of the relationships between structures, often achieved by the study of human cadaveric material, models, and virtual resources. This study sought to identify the approaches taken in the United Kingdom and Republic of Ireland to deliver anatomical education through online means. Data were collected from 14 different universities in the United Kingdom and Republic of Ireland and compared adopting a thematic analysis approach. Once themes were generated, they were collectively brought together using a strength, weakness, opportunity, threat (SWOT) analysis. Key themes included the opportunity to develop new online resources and the chance to engage in new academic collaborations. Academics frequently mentioned the challenge that time constrains could place on the quality and effectiveness of these resources; especially as in many cases the aim of these resources was to compensate for a lack of exposure to cadaveric exposure. Comparisons of the actions taken by multiple higher education institutions reveal the ways that academics have tried to balance this demand. Discussions will facilitate decisions being made by higher education institutions regarding adapting the curriculum and assessment methods in anatomy.  相似文献   

The international telecommunication regime in the information age     

《普罗米修斯》2012,30(4):399-414

This paper examines recent changes in the international telecommunication regime. The concept of an international regime comes from the field of international relations. Although it is not universally accepted, one of the most widely supported definitions describes an international regime as, ‘implicit or explicit principles, norms, rules, and decision‐making procedures around which actors’ expectations converge in a given area of international relations'.¹ The ‘given area’ of concern here is telecommunication. Telecommunication and the principles, norms, rules and decision‐making procedures which are relevant to it at the international level—which have been studied extensively by communications and development economics scholars²—have only rarely been the focus of international relations scholars.³ The objective of this paper is to use tools from the study of international relations to explore subject matter that has more frequently been the focus of scholars in communications, development economics, and information economics.  相似文献

开展公益教育是时代环境变化、社会转型的客观要求。家庭公益教育是公益教育的有机组成部分,是突破当前“应试型”教育模式,构建“家庭-学校-社区”三联动下系统、多元的公益教育模式的关键环节。我国家庭公益教育的开展存在诸多障碍。调查发现,这些障碍主要为家长认知障碍、家庭公益行动障碍及制度性障碍。针对这些障碍,在借鉴美国家庭公益教育经验的基础上,提出了破解之策。  相似文献   

国际背景下的我国初中化学课程的发展   总被引：2，自引：0，他引：2  

魏冰 《教育理论与实践》2004,(12)

从国际影响的视角看,可将我国初中化学课程在1978年到2001年间的变化划分为四个阶段。在每一个阶段,初中化学课程都受到国际的影响,在不同阶段所影响的内容与程度是不同的,当国际趋势符合国内的教育(课程)政策时,它便能较大幅度地影响化学课程,反之则弱。  相似文献

我国入世过渡期结束、外贸经营权放开以后，以前为国有专业外贸公司提供货源的厂家获得外贸出口权，国有专业外贸公司面临失去货源和客户的风险。为此，90年代后半期以后不少专业外贸公司纷纷向实业化转型。该文根据有关经济学理论对此问题进行了探讨，并对今后国有专业外贸公司的发展问题提出了自己的建议。  相似文献
