人白细胞介素-24基因的克隆、表达和纯化

目的对人白细胞介素-24(hIL-24)进行克隆、表达和纯化。方法分离人外周血单个核细胞,ConA刺激培养,提取细胞总RNA,应用RT-PCR技术从外周血单个核细胞中扩增hIL-24成熟肽编码区,定向克隆至融合表达载体pGEX-4T-1,重组载体pGEX-4T-1/hIL-24经DNA测序鉴定后,转化E.coliBL21(DE3),IPTG诱导表达,阴离子交换层析纯化融合蛋白,SDS-PAGE和Westernblot鉴定。结果所得hIL-24基因经序列分析,与GenBank公布一致。所构建融合表达载体pGEX-4T-1/hIL-24测序正确,转化BL21(DE3)后,37℃诱导表达相对分子质量约为44000的融合蛋白,主要以包涵体形式存在,占菌体总蛋白的30.63%。经纯化后,纯度达85%以上。Westernblot检测能与兔抗人IL-24的多克隆抗血清发生结合反应。结论已成功构建了hIL-24的融合表达载体pGEX-4T-1/hIL-24,并在大肠杆菌中高效表达,纯化后获得了高纯度的融合蛋白,为hIL-24的功能及活性研究奠定基础。     

基于信息物理融合的骨折复位机器人系统构建

针对骨折治疗中传统复位方法（手法复位、牵引复位、手术复位）存在的二次损伤、肌能失调、患肢僵硬、破坏血运及术后矫正动态性能差等问题,提出了一种人-机-物融合的信息物理系统（CPHS）用于指导机器人的复位动作。首先,从CPHS的数字孪生、信息感知、系统集成、手术流程、模拟复位等方面论证了并联机器人信息物理系统的构成,将机器人的高定位精度及可重复性与微创方法有效结合,从而指导医生完成仿真规划及术中监控等一系列操作;其次,根据临床骨折复位过程,在机器人操作下对5组不同骨折姿态的模拟骨折病例进行了复位实验;最后,计算出每组实验复位后的移位残余及角度误差,并与传统复位方法的相应数据进行对比。实验结果表明,CPHS骨折复位机器人相较于传统复位方法,在骨折复位过程和患者术后康复上均有着明显的优势。     

Cognitive work analysis to comprehend operations and organizations in the mining industry

Complex industrial systems, including mining, have a prominent challenge in understanding the interrelationship among the cognitive processes, working environment and available equipment. The concept of cognitive work analysis(CWA) transcends the traditional analytic methods of evaluating human tasks solely based on perceptual and physical traits, and rather implements the notions of behavioral and cognitive awareness indispensable for the intricacy of modern technology. In the last few decades, academic and industrial settings employ this type of analysis to set a suitable standard for a system's safety feasibility, and as a result reduce human-based errors. This research paper analyzes current CWA methods and proposes a five-level quantification model portraying the overall cognitive quality of a mining operation.     

Scanning electron microscopy of nerve fibers in human fetal cochlea

The cochleas of four human fetuses ranging 22–25 weeks gestation were studied by scanning electron microscopy (SEM) for the purpose of obtaining a better understanding of the nerve fiber arrangement in the human ear. After critical point drying, the specimens were dissected and the floor of the tunnel of Corti and the outer wall of Nuel's space were exposed for observation. Upper cochlear turns, especially the apical turn, seemed to be still immature. Observed nerve fibers were classified into three types:

• 1 Spiral fibers: Fibers traveling basalward and following the shape of the cochlea were found in both the tunnel of Corti and Nuel's space and believed to be the afferent nerves responsible for innervating the outer hair cells
• 2 Radial fibers: radiating outward from the osseous spiral lamina—one such radial fiber transversing high in the tunnel space (supposedly the efferent nerve servicing the outer hair cells), and another sort of radial fiber (found crossing the tunnel floor), the nature of which was uncertain.
• 3 Irregular fibers: Consisting of thin, randomly running fibers within the cochlea. The destination of these fibers was not determined, but possibly they represent transitory nerve branchings of afferent or more probably efferent nerves, which would later regress during maturation.

     

基于模糊识别的驾驶员疲劳检测

汽车驾驶员疲劳驾驶是导致交通事故的重要原因之一,通过监测驾驶员的眼睛可以判别驾驶员的疲劳程度。对驾驶员眼睛的张开程度、眨眼频率、闭眼持续时间占空比等状态量进行检测和运算分析,提出利用模糊识别算法判别驾驶员眼睛疲劳状态。实验结果表明,该方法能有效识别驾驶员的疲劳状态,实时性好,准确率高。

Assessing the effects of gamification in the classroom: A longitudinal study on intrinsic motivation,social comparison,satisfaction, effort,and academic performance

Gamification, the application of game elements to non-game settings, continues to grow in popularity as a method to increase student engagement in the classroom. We tested students across two courses, measuring their motivation, social comparison, effort, satisfaction, learner empowerment, and academic performance at four points during a 16-week semester. One course received a gamified curriculum, featuring a leaderboard and badges, whereas the other course received the same curriculum without the gamified elements. Our results found that students in the gamified course showed less motivation, satisfaction, and empowerment over time than those in the non-gamified class. The effect of course type on students' final exam scores was mediated by students' levels of intrinsic motivation, with students in the gamified course showing less motivation and lower final exam scores than the non-gamified class. This suggests that some care should be taken when applying certain gamification mechanics to educational settings.     

Empathy and Modern Technology: A Neuroergonomics Perspective

The primary purpose of this paper is to discuss the role of empathy in the design of advanced systems in manufacturing and service industries in order to ensure suitable working conditions for employees from the social and technological point of view. The origins and components of empathy are briefly reviewed. The neural underpinnings of three components of empathy, including cognitive, emotional, and behavioral aspects, are considered in the context of human–human and human–machine interactions, as well as design of working environments. Finally, the potential advantages of applying empathy‐related knowledge to the design and development of human‐centered technology are discussed.
