Research at home: Being creative in running an undergraduate final research project in Food Science amidst the COVID‐19 crisis

The pandemic of coronavirus disease (COVID‐19) in early 2020 has led to tremendous disruptions in education systems worldwide, including the closure of majority of education institutions and the shifting from face‐to‐face learning toward remote learning. More than 70% of the world's student population were affected by such a disruptive event, inclusive of undergraduate students in their final year preparing their research project. Senior students in Food Science generally perform laboratory‐oriented research project, which can be problematic due to the closure of laboratories and universities. I wrote this article to give an insight into conducting final year research projects from home amidst the COVID‐19 crisis based on my personal experience as a research supervisor. The research methods discussed include literature review, analysis of secondary data, survey research, simple food processing, remote sensory evaluation, and glycemic index analysis. Regardless of the type of research chosen, consistent guidance and support from a research supervisor toward the student, both academic and moral, appears to be a fundamental factor determining the success of the student in completing his/her final research project, particularly during these difficult times.     

Mandatory Virtual Design Studio for All: Exploring the Transformations of Architectural Education amidst the Global Pandemic

Virtual design studio (VDS) has been a part of the discourse of architectural pedagogy for the past two decades. VDS has been showcased as a potential educational tool in schools of architecture often in controlled, pre‐designed experiments. However, the global COVID‐19 pandemic has forced most schools to move their design studios into virtual space. This article aims to explore the potential advantages and shortcomings of VDS during the COVID‐19 quarantine from the perspective of students in a department of architecture. The study investigates three aspects of VDS namely, participating students’ evaluation of the virtual studio experience, the effectiveness of VDS in achieving the studio’s expected learning outcomes and the evaluation process for final design projects. Some 360 students from eight consecutive design studios participated in the study. The results indicate improvement in students’ ability to conduct independent research and in learning new computer‐aided design (CAD) software. Furthermore, the study finds VDS to be much more applicable for third‐ and fourth‐year students. The results also show a significant decline in background informal peer learning among students. Further studies are needed to address the implementation of a more immersive social experience in VDS.     

新型冠状病毒肺炎患者血液中红细胞体积参数的变化

目的观察新型冠状病毒肺炎患者血液中RDW-SD、RDW-CV和MCV三种红细胞体积参数的变化。方法以确诊为新型冠状病毒肺炎患者17例作为病例组,64例普通肺部感染患者作为对照组,比较两组患者的RDW-SD、RDW-CV和MCV均值。结果新型冠状病毒肺炎组的RDW-SD、RDW-CV和MCV均值分别为39.7、12.3和88.5;普通肺部感染组的RDW-SD、RDW-CV和MCV均值分别为43.7、13.7和88.4;病例组与对照组比较RDW-SD(t=3.168,P=0.002),RDW-CV(t=3.990,P<0.001)有统计学差异,MCV(t=0.038,P=0.970)无统计学差异;RDW-SD、RDW-CV和三种红细胞体积参数联合检测的ROC曲线下面积分别为0.674、0.677和0.712。结论新型冠状病毒肺炎患者血液中红细胞体积参数RDW-SD和RDW-CV在发病过程中有明显变化,而普通肺部感染患者血液中红细胞体积参数在发病过程中变化不明显;RDW-SD、RDW-CV和MCV这三种红细胞体积参数联合检测可以辅助鉴别诊断新型冠状病毒肺炎与普通肺部感染。     

非医学类高校防控新冠疫情措施的探析

新型冠状病毒是一种新发现的传染性很强的病毒,病毒的潜伏期长,全球存在很多被感染后的无症状者和复阳者。高校人员集中、生源广泛、学生活动范围大、普遍实行寄宿制、大班教学等特点,加之非医学类高校对健康教育及基础医疗知识的普及和实践不够重视,学生在面对突发公共卫生事件时缺乏基本的防控意识和自救、互救能力。因此这类院校更要积极做好新型冠状病毒肺炎疫情的防控。根据目前非医学类高校在突发公共卫生事件防控方面存在的问题,结合新冠病毒的感染、传播特点,从设立长效应急队伍或机构、制定行之有效地防控和应急预案,在落实师生健康教育课程、监测预警、建设医疗应急队伍和及时进行疫后心理疏导等方面提出了对策和建议。     

第19届世界杯足球赛决赛阶段各队进攻进球特征规律研究

通过对第19届足球世界杯32个参赛队64场比赛143个进球的特征统计研究,结果表明,本届世界杯总进球数是前三届由逐届下降转为上升的折点。在90 min比赛中,下半场进球数高于上半场;全场比赛结束前15min进球数最多,比赛开始第一个15 min进球数最少。罚球区仍然是进球最多的区域,其次是罚球区前沿区域。前锋队员进球最多,依次是中场、后卫队员。在各进球方式中抢点脚射进球数位居第一,依次是头顶球进球、运球突破脚射进球。定位球进攻进球数明显列各进攻形式之首,依次是中路进攻进球、边路进攻进球。由前场组织发动进攻进球率最高,依次是中场发动进球、后场发动进球。从球门下部进球率较高,其中球门2区进球数最多,球门5区进球数最少。进球前经过队员之间"1"次传球配合后射门进球率最高,而经过"5"次以上传球后进球数明显减少。     

对虾白斑综合征病毒VP19基因的克隆和序列分析
