在《植物地理学》中,关于植物分类的种类名称问题,既有中文名字又有拉丁文名字,同一种类的植物,其中文名字不同地区叫法不同,有很大差异,但拉丁文的叫法只有一个,现就拉丁文的名称表示方式——双名法及其新组合做一些探究。 相似文献

Dissection has long been the accepted method for teaching anatomy to medical students. More recently, some educators have suggested that easier, cheaper, alternative methods are just as effective. But what do the students think? This paper aimed to identify what undergraduate medical students learn, how they cope, and what effects participating in dissection has on them as individuals. A cohort of 267 second year medical students at Otago Medical School were invited to complete three online surveys; before their first dissection laboratory class, after their first musculoskeletal system dissection and following the last semester of studying anatomy. Open‐ended questions showcasing the attitudes, beliefs, and opinions on what dissection had taught the medical students over years two and three were analyzed. A general inductive approach was used and common emergent themes were identified. In total, 194 students completed the second, and 108 students completed the third questionnaire. Students commonly conveyed dissection as an appropriate and valuable educational tool, useful for teaching and learning anatomical knowledge and relationships, appreciating the body in three‐dimension, teamwork, and how to cope with death/dead bodies. The noted effects of personal growth while participating in dissection were highly varied, but in general, impacted positively on the majority of students. This study shows that at Otago Medical School the students also believe that dissection is not only a useful tool to learn anatomy but also that it fosters teamwork, assists professional development and helps them come to terms with death and dying.

Despite the importance of body donation for medical education and the advancement of medical science, cadaveric donation remains suboptimal worldwide. The purpose of this study was to evaluate the willingness of body donation in Greece and determine the characteristics of donors. This cross‐sectional questionnaire survey was conducted from January to June 2011. A specially designed questionnaire was distributed to 1,700 individuals who were randomly selected from five major Greek cities. It was found that higher educational levels (P = 0.002), annual family income below 30,000 Euros (P = 0.001), guaranteed employment status (P = 0.02), and the presence of comorbid conditions (P = 0.004) seemed to affect potential donors' willingness for cadaveric donation. Those with strong religious beliefs were found to be unwilling to donate their bodies to medical science. Interestingly, the majority of participants who believed that hospitalized patients are deceived or are used for harmful experiments were willing to become whole body donors (P = 0.043). In Greece, the rate of body donation to medical science remains low, and most Greek citizens are not willing to become body donors. Efforts to encourage discussions about whole body donation should be implemented in order to improve current low levels of donation. Anat Sci Educ. © 2012 American Association of Anatomists. 相似文献

若要对新风机进行噪声分析及优化,必须建立其CAD参数化模型.而新风机通道形状十分复杂,采用传统CAD软件正向准确地设计出实体模型较为困难.基于此,采用逆向工程技术对XHBX-D2TH型号的新风换气机进行三维建模与装配.首先,采用三维数字化仪获取实物表面三坐标信息;然后,应用逆向工程软件Geomagic Studio对扫描仪获得的点云数据进行预处理和封装;最后,利用软件CATIA进行实体建模与装配,所得结构符合工程实际. 相似文献

盐胁迫对不同品种小黑麦光合特性和生长的影响 总被引:1,自引:0,他引:1
分别用0,50,100,200,300 mmol/L NaC1溶液处理6个品种的小黑麦幼苗,15天后测定其净光合速率、蒸腾速率、气孔导度、胞间CO2浓度,以及根长、苗高、鲜重.结果表明,50 mmol/L NaC1处理对小黑麦的光合速率和幼苗生长有轻微促进作用,随着NaC1浓度增大,幼苗表现为光合速率、蒸腾速率、气孔导度降低,胞问CO2浓度也呈现规律性变化,幼苗生长受到抑制.综合比较以上指标,在供试的6个小黑麦品种中,抗盐性强的品种有NTH1888和NSWH11,WOH939抗盐性中等,抗盐性弱的品种为黔中3号、劲松49、澳洲黑麦. 相似文献

Teaching internal structures obscured from direct view is a major challenge of anatomy education. High-fidelity interactive three-dimensional (3D) micro-computed tomography (CT) models with virtual dissection present a possible solution. However, their utility for teaching complex internal structures of the human body is unclear. The purpose of this study was to investigate the use of a realistic 3D micro-CT interactive visualization computer model to teach paranasal sinus anatomy in a laboratory setting during pre-clinical medical training. Year 1 (n = 79) and Year 2 (n = 59) medical students undertook self-directed activities focused on paranasal sinus anatomy in one of two laboratories (traditional laboratory and 3D model). All participants completed pre and posttests before and after the laboratory session. Results of regression analyses predicting post-laboratory knowledge indicate that, when students were inexperienced with the 3D computer technology, use of the model was detrimental to learning for students with greater prior knowledge of the relevant anatomy (P < 0.05). For participants experienced with the 3D computer technology, however, the use of the model was detrimental for students with less prior knowledge of the relevant anatomy (P < 0.001). These results emphasize that several factors need to be considered in the design and effective implementation of such models in the classroom. Under the right conditions, the 3D model is equal to traditional laboratory resources when used as a learning tool. This paper discusses the importance of preparatory training for students and the technical consideration necessary to successfully integrate such models into medical anatomical curricula. 相似文献

This paper details the creation of a human gross anatomy laboratory from a defunct chemistry laboratory at West Liberty University, a small primarily undergraduate institution in West Virginia. The article highlights important considerations with regard to the development of a human gross anatomy laboratory including access to human gifts; assessment of the space for size, security, and privacy; assessment of the utilities; acquisition of a dissection table; ventilation; aesthetics in functional design; expenses; and sustainability. The report also identifies favorable conditions and potential pitfalls regarding the creation of a human gross anatomy laboratory. This paper demonstrates that a human gross anatomy laboratory can be created quickly and at little expense. 相似文献
