| 1 | The association of layperson characteristics with the quality of simulated cardiopulmonary resuscitation performance显示文摘BACKGROUND: Few studies have examined the association of layperson characteristics with cardiopulmonary resuscitation(CPR) provision. Previous studies suggested provider characteristics, including age and gender, were associated with CPR quality, particularly chest compression(CC) depth. We sought to determine the association of subject characteristics, including age and gender with layperson CPR quality during an unannounced simulated CPR event. We hypothesized shallower CC depth in females, and older-aged subjects.METHODS: As part of a larger multicenter randomized controlled trial of CPR training for cardiac patients' caregivers, CPR skills were assessed 6 months after training. We analyzed associations between subject characteristics and CC rate, CC depth and no-? ow time. Each variable was analyzed independently; signi? cant predictors determined via univariate analysis were assessed in a multivariate regression model.RESULTS: A total of 521 laypersons completed a 6-month CPR skills assessment and were included in the analysis. Mean age was 51.8±13.7 years, 75% were female, 57% were Caucasian. Overall, mean CC rate was 88.5±25.0 per minute, CC depth was 50.9±2.0 mm, and mean no-flow time was 15.9±2.7 sec/min. CC depth decreased signi? cantly in subjects >62 years(P<0.001). Male subjects performed deeper CCs than female subjects(47.5±1.7 vs. 41.9±0.6, P<0.001).CONCLUSION: We found that layperson age >62 years and female gender are associated with shallower CC depth. | Marion Leary David G.BucMer Daniel J.Ikeda Daiane A.Saraiva Robert A.Berg Vinay M.Nadkarni Audrey L.Blewer Benjamin S.Abella | 2017 | World Journal of Emergency Medicine2017，8，1： | 5 |

| 3 | 心理学胜过教育学:评中国的“新教育实验”显示文摘盖洛普民调显示,在世界范围内,由于中小学教育中的“远离学习”会进一步导致职场中“远离工作”的问题,这会给全球生产力带来每年高达7万亿美元的损失。朱永新教授在他的China’s New Education Experiment in Action一书中,讲述了遵循他们的原则的创新学校所取得成功的各种故事。近年来在教育领域鲜为人知的心理学研究发现,将有助于进一步解释朱教授的新教育实验为什么能取得成功。通过将重点放在学生的积极性和参与度上,应用新教育实验原则的学校既能帮助学生取得学业成就,又能使其“过上快乐、完整的教育生活”。展望未来,所有的教育变革,无论它们发生在哪里,都将面临着挑战。在新教育实验中,这些学校在迎接不可避免的挑战时采用的一种积极的潜在方法,比如对这些学校所使用的科学的心理环境测量方法的价值,本文也进行了讨论。 | | 2022 | 华东师范大学学报(教育科学版)2022，40，10： | 0 |
| 4 | DEM Fusion using a modified k-means clustering algorithm显示文摘Digital elevation models(DEMs)are a necessary dataset for modelling the Earth’s surface;however,all DEMs contain error.Researchers can reduce this error using DEM fusion techniques since numerous DEMs can be available for a region.However,the use of a clustering algorithm in DEM fusion has not been previously reported.In this study a new DEM fusion algorithm based on a clustering approach that works on multiple DEMs to exploit consistency in the estimates as indicators of accuracy and precision is presented.The fusion approach includes slope and elevation thresholding,k-means clustering of the elevation estimates at each cell location,as well as filtering and smoothing of the fusion product.Corroboration of the input DEMs,and the products of each step of the fusion algorithm,with a higher accuracy reference DEM enabled a detailed analysis of the effectiveness of the DEM fusion algorithm.The main findings of the research were:the k-means clustering of the elevations reduced the precision which also impacted the overall accuracy of the estimates;the number of final cluster members and the standard deviation of elevations before clustering both had a strong relationship to the error in the k-means estimates. | Colleen E.Fuss Aaron A.Berg John B.Lindsay | 2016 | International Journal of Digital Earth2016，9，12： | 0 |
| 5 | The Application of Model-Based Systems Engineering to Rural Healthcare System Disaster Planning:A Scoping Review显示文摘Disasters and other emergency events have complex effects on human systems,particularly if the events are severe or prolonged.When these types of events happen in rural communities,the resources of the local public health,healthcare,and emergency response organizations can be quickly depleted or overwhelmed.Planning for emergencies can help to mitigate their impact.Model-based systems engineering(MBSE)methods,including computer simulations,can provide insight on how best to prepare for these events and to explore the effects of varying approaches and resource utilization.To best apply these methods for improving disaster management in rural settings,a synthesis of the current body of evidence in this field is needed.The objective of this scoping review was to provide a descriptive overview of the application of computer simulation based on MBSE approaches to disaster preparedness and response for rural healthcare systems.Six studies met inclusion criteria,and varied in terms of MBSE method used,healthcare setting,and disaster type and context considered.We identified a gap in the research regarding the application of MBSE approaches to support rural healthcare disaster preparedness planning efforts.Model-based systems engineering and systems thinking,therefore,represent novel methods for developing tools and computational simulations that could assist rural communities better prepare for disasters. | Thomas A.Berg Kelsi N.Marino Kristina W.Kintziger | 2023 | International Journal of Disaster Risk Science2023，14，3： | 0 |
| 6 | 自身免疫疾病——病因学、诊断和治疗的新认识 1999年1月22日~23日联邦医师协会第23届学科间研讨会“医学进展和继续教育”显示文摘有两项中心任务有待免疫系统解决:①识别什么是有害的'异己',并且与它做斗争;②识别什么是自己的,不去攻击而去保护它。细胞免疫与体液防御机制一样受着两个 T 辅助细胞亚群 T_(H1)和 T_(H2)细胞的调控,二分法对于理解自身免疫病变特别重要。从此观点出发。 | Peter A.Berg 郝连杰 | 1999 | 德国医学1999，16，6： | 0 |
| 7 | Genetic diseases conferring resistance to infectious diseases显示文摘This review considers available evidence for mechanisms of conferred adaptive advantages in the face of specific infectious diseases.In short,we explore a number of genetic conditions,which carry some benefits in adverse circumstances including exposure to infectious agents.The examples discussed are conditions known to result in resistance to a specific infectious disease,or have been proposed as being associated with resistance to various infectious diseases.These infectious diseasedgenetic disorder pairings include malaria and hemoglobinopathies,cholera and cystic fibrosis,tuberculosis and Tay-Sachs disease,mycotic abortions and phenylketonuria,infection by enveloped viruses and disorders of glycosylation,infection by filoviruses and NiemannePick C1 disease,as well as rabies and myasthenia gravis.We also discuss two genetic conditions that lead to infectious disease hypersusceptibility,although we did not cover the large number of immunologic defects leading to infectious disease hypersusceptibilities.Four of the resistance-associated pairings(malaria/hemogloginopathies,cholera/cystic fibrosis,tuberculosis/Tay-Sachs,and mycotic abortions/phenylketonuria)appear to be a result of selection pressures in geographic regions in which the specific infectious agent is endemic.The other pairings do not appear to be based on selection pressure and instead may be serendipitous.Nonetheless,research investigating these relationships may lead to treatment options for the aforementioned diseases by exploiting established mechanisms between genetically affected cells and infectious organisms.This may prove invaluable as a starting point for research in the case of diseases that currently have no reliably curative treatments,e.g.,HIV,rabies,and Ebola. | Isabelle C.Withrock Stephen J.Anderson Matthew A.Jefferson Garrett R.McCormack Gregory S.A.Mlynarczyk Aron Nakama Jennifer K.Lange Carrie A.Berg Sreemoyee Acharya Matthew L.Stock Melissa S.Lind K.C.Luna Naveen C.Kondru Sireesha Manne Bhavika B.Patel Bierlein Mde la Rosa Kuei-Pin Huang Shaunik Sharma Hilary Z.Hu Sri Harsha Kanuri Steve A.Carlson | 2015 | Genes & Diseases2015，2，3： | 0 |
