七彩年华

雨后,大自然送给人间一件别致的礼物——七彩虹,清晰地折射出阳光那迷人的颜色,青春则犹如这雨后的彩虹,充满了丰富的色彩。赤、橙、黄、绿、青、蓝、紫亦如青春的音符,谱奏着生命中最美丽的旋律。     

阿旃陀洞穴的宝藏

隐藏在印度农村,距孟买东约200英里的30座阿旃陀洞穴,堪与世界七大奇迹并列。这些面积广大的佛教寺院均为2200—1300年以前从险峻的玄武岩悬崖上用凿斧和錾子挖掘而成的。印度其他1000个宗教山洞都无法与阿旃陀洞内那些激动人心的壁画相比,可以说这些阿旃陀洞穴的创     

非洲国家学校教学中的民族语

尽管非洲国家在发展教育中取得了显著成绩,但是在那里有效的教育系统直到现在还是不完备的。这首先表现为由于学生被淘汰和留级造成学校失去质量水平。为了找到解决教育质量问题的方法,非洲国家正在致力于把课程引导到使教育具有非洲特征的轨道上来。而实现这个任务与用地方语翻译教材、用地方语编写教材和教学参考书紧密相关。人们注意到对多数学生用他们所不熟悉的欧洲语言授课是教育质量低、淘汰人数多的原     

短距离爬泳的耐力

专项耐力是指机体用一定速度和强度持续完成该专项的工作能力.当运动员参加短距离项目比赛时,我们认为专项耐力显得更重要.然而,如果认为在赛前专项耐力的训练是起压倒一切的作用,那么这种看法就值得怀疑了.同样,从重要性来说,运动员应该制订大强度短距离游(25,50和100米)的训练和竞赛计划,所要创造的条件,类似他在比赛中所遇到的条件.     

研讨会:在一起耐心地讨论

亲爱的刘默耕: 我非常乐意能够为你们的《科学启蒙教育》刊物寄送乔治·托基塔写的文章,这篇文章是在他入院做手术之前写完的,幸运的是文章写得很好。他要我加上提要。 对“懒惰而反应迟缓的孩子”用他的探究法与我在育才学校以录相授课期间所见到的许多方法比较,我认为他的方法是很有趣的。也许你们的读者也同样通过看录相带来提高他们的理解能力。     

Effects of adding a preceding run-up on performance, blood lactate concentration and heart rate during maximal intermittent vertical jumping

In this study, we examined the effects of a prior run-up on intermittent maximal vertical jump performance. Seven regionally ranked male volleyball players volunteered to participate in the study. They performed three randomized tests: (1) six repeated intermittent maximal jumps (jump condition), (2) six repeated intermittent run-ups (run-up condition), and (3) six repeated run-ups followed by maximal jumps (run-up plus jump condition). All performances were assessed and blood lactate concentration and heart rate were measured before and after each of the tests. Mean ( +/- ) jump performance (64.7 +/- 2.3 cm) increased significantly (P = 0.02) over the course of the jump condition and was significantly higher (P < 0.001) than for the run-up plus jump condition (58.0 +/- 3.2 cm), which tended to decrease with repetition. Blood lactate concentration was significantly higher in the run-up plus jump condition (3.73 +/- 0.24 mmol . l(-1)) than in the jump (2.61 +/- 0.26 mmol . l(-1), P = 0.02) and run-up (2.86 +/- 0.18 mmol . l(-1), P = 0.03) conditions. The increase in heart rate was significantly higher both in the run-up plus jump condition (33 +/- 6 beats . min(-1), P = 0.05) and run-up condition (33 +/- 4 beats . min(-1), P = 0.02) than in the jump condition (21 +/- 3 beats . min(-1)). The results indicate that the addition of run-ups probably impeded performance in the repetition of vertical jumps.     

研讨会:在一起耐心地讨论(续完)

每次研讨结束后,你应在“小科学家日记”上记录下全班都同意的论述,这些论述可用孩子们自己的语言来表达。在某些情况下,孩子们可能找不出各种不同论述中的共同点,这就需要教师的适时引导,去指点一下孩子们的思路并且提供一个能够概括他们     

揭示奇哲文化个性之作

熊十力可以称得上是二十世纪中国思想界的奇哲,他为人刚直不阿、风骨嶙峋,其哲学思想亦气势磅礴、不同凡响。他穷毕生精力砥励学问,终于在荟萃古今中西思想精华的基础上建立起一套博大精深的哲学体系。 他既注意紧扣时代脉搏,以新思想之盎然生机抗拒传统文化的腐朽僵化,又时时警惕着西方社会中的人性异化和价值旁落,力图开创一个与宇宙物质生命和谐融洽的人文精神世界,在物化和异化的时代氛围中重建具有创造精神的、刚健自强的道德人生。正是上述独到见解,使熊十力哲学瑰宝在遭受了政治批判年代的摧残和“死心塌地向西走”之狂潮的冲击后,于当今改革开放面向世界和重建民族文化“根芽”的时代精神中大放异彩,受到海内外学者的关注。     

Validation of a laboratory and hospital information system in a medical laboratory accredited according to ISO 15189

Introduction

The aim of the study was to present a protocol for laboratory information system (LIS) and hospital information system (HIS) validation at the Institute of Clinical Chemistry and Laboratory Medicine of the Merkur University Hospital, Zagreb, Croatia.

Materials and methods:

Validity of data traceability was checked by entering all test requests for virtual patient into HIS/LIS and printing corresponding barcoded labels that provided laboratory analyzers with the information on requested tests. The original printouts of the test results from laboratory analyzer(s) were compared with the data obtained from LIS and entered into the provided template. Transfer of data from LIS to HIS was examined by requesting all tests in HIS and creating real data in a finding generated in LIS. Data obtained from LIS and HIS were entered into a corresponding template. The main outcome measure was the accuracy of transfer obtained from laboratory analyzers and results transferred from LIS and HIS expressed as percentage (%).

Results:

The accuracy of data transfer from laboratory analyzers to LIS was 99.5% and of that from LIS to HIS 100%.

Conclusion:

We presented our established validation protocol for laboratory information system and demonstrated that a system meets its intended purpose.
