Visual Teaching Strategies for Children with Autism

Most traditional teaching methods used in working with autistic children rely heavily on auditory instruction. Autism is a spectrum disorder, with a wide variety of needs and abilities within the range of children with the disability, and not all children within this grouping benefit from copious oral instruction. This paper discusses the type of child that would benefit from an educational approach that emphasises a visual approach and discusses the benefits and disadvantages of some of the more well known of these.     

Filmless radiology in the Emergency Department

The introduction of standardization in image formatting allowed the development of a picture archiving and communication system, or filmless radiology. In practice, we have found advantages in quick access and availability, image manipulation, and cost savings to outweigh the disadvantages of portability and system down time.     

数字X线摄影和计算机X线摄影的应用比较与评价

探讨数字X线摄影(DR)和计算机X线摄影(CR)两大数字化摄影技术的临床应用.材料和方法:用德国Pehamed公司产测试板分别测量DR和CR的空间分辨率,并从100例两者所摄得的正位胸片中,分析图像质量,统计受检者的照射剂量,比较在技术操作、图像质量控制与后处理技术、工作效率、医院效益等方面的优势.结果:DR和CR均提高了图像质量,不同程度减低了被检者所受X线照射量,通过缩短检查和发报告的时间加快了工作效率,带来更高的效益,DR较之CR更具优势.结论:DR与CR相比DR图像质量、后处理功能、工作流程能力、病人吸收剂量均明显优于CR,DR具有更广阔的前景.     

汉语及图片语义加工机制的fMRI研究

目的利用功能磁共振成像(fMRI)技术探讨汉字及图片语义加工的脑机制。方法对13名正常青年受试者进行视觉方式呈现汉字及图片语义辨别任务的fMRI扫描,采用AFNI软件进行数据分析和脑功能区活动图像。结果fMRI显示两种任务均激活了左侧顶下小叶、额中回、额下回、右侧小脑及双侧梭状回、舌回、枕中回、枕下回、辅助运动区。其中左侧顶下小叶、额中回及双侧枕中回、梭状回在图片语义辨别任务激活明显强于汉字任务,有显著性差异(P<0.05)。结论汉字及图片语义的脑加工均存在偏侧化现象,图片语义的脑处理有更多的脑活动参与完成。     

医学影像传输及储存系统数据库中应用云计算的设计

目的:在医学影像传输及储存系统(PACS)中,数据库是其整个系统的主要组成部分。数据库文件结构的建立是编制程序的基础,也是维护工作的依据。为满足患者对医疗技术水平的要求,研究出不必对现有医疗设备进行升级换代或购买新软件,而是设计一个"私有云",在"云"内进行数据处理和数据储存,实现对图像储存及图像的后处理。方法:将现有的PACS系统与医疗设备及用户端的PC使用"云计算"技术将其对接,使数据储存和数据运算等工作在云内进行。结果:"云"内储存的存储空间得到了极大的提升,且单独工作站瘫痪时不会引起数据丢失;因"云"内计算采用了分布式和并行式计算,大大提高了运算能力。结论:PACS数据库中应用"云计算"能有效的提高数据存储和数据处理方面的能力。     

Tracking the status of language development in language‐minority kindergartners

As our world becomes increasingly multicultural in nature, multilingual skills constitute an everyday phenomenon in schools. Since most of the second‐language research has focused on school‐age students, more research had to be conducted with language‐minority students at the kindergarten level in order for psychologists and educators to develop effective and efficient systems for evaluating and tracking the developmental status of young language‐minority children. The purpose of this study was to investigate the potential usefulness of a standardized continuous progress measure, the Picture Naming Individual Growth and Development Indicator, to longitudinally assess language development in 23 language‐minority children, as well as in 13 native English‐speaking children. Results indicated that we could use the Picture Naming Individual Growth and Development Indicator to detect differences in first‐language and second‐language development in language‐minority children, as well as to detect differences between the two groups of children in their expressive English‐language skills.     

医学英语词汇教学探讨

通过医学构词学习、文化背景介绍、实际应用指导三个方面对医学英语词汇教学进行了探讨,旨在提高教学效果,为专业课程学习服务。     

以提高医学影像学专业本科生实践技能水平为目标的实验课程改革

医学影像设备飞速发展,对医学影像学专业人才实践技能水平提出更高要求。然而传统（CTMR诊断学》实验教学存在图像质量差、教学资源不平衡、学生实践技能训练不足、课程考核不能体现实践技能水平等弊端,不利于人才培养。通过改善实验室硬件设施、编写实验指导、鼓励学生主动学习、加强实践技能考核、多渠道培养教师等措施,提高该课程的实验教学质量与学生实践技能。调查发现,92．9％的学生对改革后的实验课程教学表示满意。上述措施今后将应用于医学影像诊断学的所有子课程教学,以促进医学影像学专业人才培养。     

Blood gases, electrolytes and metabolic monitoring in children with acute failure of vital functions

The priority of direct monitoring of blood gases in Paediatric Intensive Care Units (PICU) increased substantially after introduction of the Deep Picture™ method and Oxygen Status Algorithm (OSA) (1) into medical practice. We used the advantages of these methods as a prerequisite for a more detailed and deeper analysis of the blood oxygen profile (2, 3). The aims of the present paper were:

• 1

   To illustrate the applicability of the capacity coefficients β₁₀, β₂₃, β_{5. 4} of the transported oxygen and the "Useful Ratio" (UR) index of the haemoglobin oxygen, previously described by us, and the benefit derived from differentiation of the states of hyperoxia, normoxia and hypoxia; hyperoxaemia, normoxaemia and hypoxaemia on the Blood Oxygen Binding Curve (BOBC) in critically ill newborns, infants and children.
• 2.

   To expand the diagnostic capacity of the Blood Gas Map (BGM) used with the OSA in children and to supplement the arterial oxygen diagnostics with new indices that reflect the relationship between oxygen uptake and oxygen transported in the body.
• 3.

   To share our experience in PICU related to the acid-base-electrolytes relationship and to the possibility of assessing the reno-hepatic regulation according to the changes of the acid-base status in critically ill children.

     

数字减影血管造影图像数据备份存储方式探讨

目的探讨适合数字减影血管造影（DSA）图像备份存储的最简便和最实惠的存储方式。方法将429例具有完整临床资料患者的DSA图像资料进行光盘刻录、图像存储和传输系统（PACS）存储和USB移动存储。对3种方法的备份耗费的时间、调阅所需时间、所耗费用、操作的简便性及图像质量进行比较。结果USB移动储蓄的备份所需时间、调阅所需时间、费用、每例患者备份成本明显低于前两种方法，而且操作简单、图像质量好。结论USB移动存储是最简便和最实惠的DSA图像数据存储方式，可作为常规方法加以推广。
