| 2 | 建立急诊潜在危重病评分预测短期死亡风险的前瞻性研究显示文摘目的:在改良早期预警评分( MEWS)的基础上进行改进、综合,以建立一种新的评分方法,并探讨这种新的评分方法早期识别急诊潜在危重病患者的可行性。方法记录1235例急诊观察室患者的临床资料,分别进行MEWS和新评分表评分,追踪所有患者的去向和预后。分别比较MEWS和新评分方法不同分数段患者14 d内死亡、>14 d死亡、住院时间>14 d、住院时间≤14 d、门诊治疗的构成比;比较MEWS和新评分方法对患者病情评价和预测预后分辨度的ROC曲线差异;比较两种评分方法及与预后的相关性。结果 MEWS 5分以上,危重患者的构成比明显增加,与5分以下比较差异有统计学意义(P<0.05)。新评分方法5分以上、住院时间>14 d的患者构成比明显增加(P<0.05);10分以上、危重患者构成比明显增加(P<0.05);15分以上、<14 d短期死亡的患者构成比明显增加( P<0.05)。就患者短期死亡危险性的预测和评估的鉴别能力而言,新评分方法ROC曲线下面积明显高于MEWS ( P<0.001)。新评分方法与预后的相关性高于MEWS(P<0.05),而且转归愈严重的组别新评分分值越大。结论 MEWS和新评分方法均可用于判断急诊患者的病情严重程度,有一定识别“急诊潜在危重病”的能力。而新评分方法可以更好地判断患者的住院周期及短期死亡风险,且只需增加血常规检查,其快速、费用低廉和操作简捷性并不亚于MEWS,更适用于国内的急诊科。 | 陈芙蓉 赵文穗 徐仲卿 | 2014 | 中国急救医学2014，34，4： | 15 |
| 3 | Comprehensive early warning of rock burst utilizing microseismic multi-parameter indices显示文摘Rock bursts have become one of the most severe risks in underground coal mining and its early warning is an important component in the safety management. Microseismic(MS) monitoring is considered potentially as a powerful tool for the early warning of rock burst. In this study, an MS multi-parameter index system was established and the critical values of each index were estimated based on the normalized multi-information warning model of coal-rock dynamic failure. This index system includes bursting strain energy(BSE) index, time-space-magnitude independent information(TSMII) indices and timespace-magnitude compound information(TSMCI) indices. On the basis of this multi-parameter index system, a comprehensive analysis was conducted via introducing the R-value scoring method to calculate the weights of each index. To calibrate the multi-parameter index system and the associated comprehensive analysis, the weights of each index were first confirmed using historical MS data occurred in LW402102 of Hujiahe Coal Mine(China) over a period of four months. This calibrated comprehensive analysis of MS multi-parameter index system was then applied to pre-warn the occurrence of a subsequent rock burst incident in LW 402103. The results demonstrate that this multi-parameter index system combined with the comprehensive analysis are capable of quantitatively pre-warning rock burst risk. | Linming Dou Wu Cai Anye Cao Wenhao Guo | 2018 | International Journal of Mining Science and Technology2018，28，5： | 9 |

| 6 | Early Warning Systems: Lost in Translation or Late by Definition? A FORIN Approach显示文摘Early warning systems(EWSs) are widely considered to be one of the most important mechanisms to prevent disasters around the globe. But as disasters continue to affect countries where EWSs have already been implemented, the striking disaster consequences have led us to reflect on the focus, architecture, and function of the warning systems. Since the 2004 Indian Ocean tsunami there has been a rapid rise in the promotion and use of EWSs to minimize disaster losses and damage. However,few researchers have addressed the question of their acceptability as an adaptive measure to the existing exposure conditions. EWSs are far more linked to emergency response and humanitarian crises and accepted technological interventions as solutions than they are to explicitly advance integrated analysis, disaster risk reduction, and policy making. A major flaw of EWSs is that the term‘‘early’’ has been essentially used in reference to the speed of hazard onset, founded on a physicalist perspective that has encouraged a considerable dependence on technology.In this article we address the need for a clear understanding of the root causes and risk drivers of disaster risk creation,as advanced in the FORIN(forensic investigation of disasters) approach, as a prerequisite for the development of more articulated EWSs that could contribute to disaster risk reduction through policy making and practice, based on integrated and transdisciplinary management, in the interest of sustainable development, and human welfare and well-being. | Irasema Alcántara-Ayala Anthony Oliver-Smith | 2019 | International Journal of Disaster Risk Science2019，10，3： | 2 |
| 7 | Real-time seismology for the 05/12/2008 Wenchuan earthquake of China: A retrospective view显示文摘The devastating 05/12/2008 Wenchuan earthquake (Mw7.9) in Sichuan Province of China showed very few precursory phenomena and occurred on a fault system once assigned to be of moderate long term seismic risk. Given the existing coverage of seismograph stations in Sichuan Province, real-time seis-mology could have been effective in avoiding some earthquake damage and helping post-earthquake emergency response. In a retrospective view, we demonstrated that the epicenter can be located with 20 km accuracy using just two broadband stations with three-component, which takes only about 10 s after the onset of the earthquake. Initial magnitude is estimated to be M7 with the Tc measurement over first 4 seconds of P waves. Better magnitude estimate can be obtained within 2 min by modeling Pnl waves for stations about 500 km away where the S waveforms are clipped. The rupture area is well revealed by teleseismically-recorded >M5 early aftershocks within two hours after the mainshock. Within a few hours, teleseismic body waves were inverted to derive a more detailed rupture process and the finite fault model can be readily used to calculate ground motions, thus providing vital information for rescue efforts in the case where no real-time strong motion records are available. | Paul SOMMERVILLE | 2009 | Science China Earth Sciences2009，52，2： | 2 |
| 8 | A study of the early warning signals of abrupt change in the Pacific decadal oscillation显示文摘In recent years, the phenomenon of a critical slowing down has demonstrated its major potential in discovering whether a complex dynamic system tends to abruptly change at critical points. This research on the Pacific decadal oscillation(PDO) index has been made on the basis of the critical slowing down principle in order to analyze its early warning signal of abrupt change. The chaotic characteristics of the PDO index sequence at different times are determined by using the largest Lyapunov exponent(LLE). The relationship between the regional sea surface temperature(SST) background field and the early warning signal of the PDO abrupt change is further studied through calculating the variance of the SST in the PDO region and the spatial distribution of the autocorrelation coefficient, thereby providing the experimental foundation for the extensive application of the method of the critical slowing down phenomenon. Our results show that the phenomenon of critical slowing down, such as the increase of the variance and autocorrelation coefficient, will continue for six years before the abrupt change of the PDO index. This phenomenon of the critical slowing down can be regarded as one of the early warning signals of an abrupt change. Through calculating the LLE of the PDO index during different times, it is also found that the strongest chaotic characteristics of the system occurred between 1971 and 1975 in the early stages of an abrupt change(1976), and the system was at the stage of a critical slowing down, which proves the reliability of the early warning signal of abrupt change discovered in 1970 from the mechanism. In addition, the variance of the SST,along with the spatial distribution of the autocorrelation coefficient in the corresponding PDO region, also demonstrates the corresponding relationship between the change of the background field of the SST and the change of the PDO. | 吴浩 侯威 颜鹏程 张志森 王阔 | 2015 | Chinese Physics B2015，24，8： | 1 |
| 9 | The Research on Synergic Development Mechanism of Oceanic Meteorology Modernization in the Huang-Bohai Region显示文摘To study the cooperative development mechanism of ocean meteorological modernization of Huang-Bohai,we analyze the situation of ocean meteorological modernization in Huang-Bohai with the method of an new five-force model and the analyses of strengths,weaknesses,opportunities and threats (SWOT analysis).As the research results shown,the advantages of ocean meteorological modernization of Huang-Bohai mainly include three aspects which are ocean meteorological observation system,ocean meteorological warning information release and the construction of ocean meteorological center;the disadvantages contain that stereo-observation ability of the ocean meteorology is insufficiency,and the precision forecast technology and the cooperative development are deficiency in ocean meteorology;opportunities also include three aspects which are 'The Belt and Road',and development of new technology and new warning system on meteorology disasters;threats mainly contain the main influencing weather system,the potential social competition and hazard factors.The use of different functions and combination innovation of five forces,i.e.,attractiveness,cohesiveness,radiating power,repulsiveness and affinity,could promote the cooperative development of ocean meteorological modernization in the Huang-Bohai. | Wang Wei Gong Xiaoqing Liu Lili Wang Qinliang | 2019 | Meteorological and Environmental Research2019，10，3： | 1 |
| 10 | Participatory Early Warning Systems: Youth, Citizen Science,and Intergenerational Dialogues on Disaster Risk Reduction in Brazil显示文摘Building national people-centered early warning systems(EWS) is strongly recommended by the United Nations International Strategy for Disaster Reduction(UNISDR). Most of the scientific literature is critical of the conventional view of EWS as a linear model with a topdown approach, in which technological features are given more attention than human factors. It is argued that EWS should be people-centered, and used for risk prevention,with an emphasis on resilience, rather than only being triggered when a hazard occurs. However, both the UNISDR and the literature fail to say how a people-centered EWS should be built, and what steps are needed to put EWS into effect. This article examines the obstacles and measures required to promote people-centered EWS,with a focus on the situation in Brazil. After assessing the institutional vulnerability of EWS, we analyze some measures that can be taken to reduce institutional vulnerability,based on experiences with a participatory citizen science educational project that involved high school students.Some guidelines are developed for adopting a bottom-up approach towards achieving the four elements of EWS—risk knowledge, monitoring, communication of warnings,and response capability—with the help of school curricula. | Victor Marchezini Rachel Trajber Dbora Olivato Viviana Aguilar Muoz Fernando de Oliveira Pereira Andra Eliza Oliveira Luz | 2017 | International Journal of Disaster Risk Science2017，8，4： | 1 |
| 11 | An Integrated Multi-Level Early Warning Method for Rainfall-Induced Shallow Landslides显示文摘Rainfall-induced landslides have occurred frequently in Southwestern China since the Wenchuan earthquake,resulting in massive loss of people’s life and property.Fortunately,landslide early-warning is one of the most important tools for landslide hazard prevention and mitigation.However,the accumulation of historical data of the landslides induced by rainfall is limited in many remote mountain areas and the stability of the slope is easily affected by human engineering activities and environmental changes,leading to difficulties to accurately realize early warning of landslide hazards by statistical methods.The proposed warning method is divided into rainfall warning component and deformation warning component because the deformation induced by rainfall has the characteristic of hysteretic nature.Rainfall,tilted angle and crack width are chosen as monitoring indexes.Rainfall grade level that contains rainfall intensity and duration information is graded according to the variation of the safety factor calculated by 3-D finite difference numerical simulation method,and then is applied using the strength reduction method and unascertained information theory to obtain the deformation grade level of several monitored points.Finally,based on the system reliability theory,we establish a comprehensive landslide warning level method that provides four early warning levels to reflect the safety factor reductions during and post rainfall events.The application of this method at a landslide site yield generally satisfactory results and provide a new method for performing multi-index and multi-level landslide early warnings. | ZHAO Binbin KONG Xiao'ang OU Wenhao LIU Yi YANG Zhi | 2020 | Earthquake Research in China2020，34，1： | 1 |
| 12 | Probabilistic rainfall thresholds in Chibo, India: estimation and validation using monitoring system显示文摘The Himalayan region has been severely affected by landslides especially during the monsoons. In particular, Kalimpong region in Darjeeling Himalayas has recorded several landslides and has caused significant loss of life, property and agricultural land. The study region, Chibo has experienced several landslides in the past which were mainly debris and earth slide. Globally, several types of rainfall thresholds have been used to determine rainfall-induced landslide incidents. In this paper, probabilistic thresholds have been defined as it would provide a better understanding compared to deterministic thresholds which provide binary results, i.e., either landslide or no landslide for a particular rainfall event. Not much research has been carried out towards validation of rainfall thresholds using an effective and robust monitoring system. The thresholds are then validated using a reliable system utilizing Microelectromechanical Systems(MEMS) tilt sensor and volumetric water content sensor installed in the region. The system measures the tilt of the instrument which is installed at shallow depths and is ideal for an early warning system for shallow landslides. The change in observed tilt angles due to rainfall would give an understanding of the applicability of the probabilistic model. The probabilities determined using Bayes' theorem have been calculated using the rainfall parameters and landslide data in 2010-2016. The rainfall values were collected from an automatic rain gauge setup near the Chibo region. The probabilities were validated using the MEMS based monitoring system setup in Chibo for the monsoon season of 2017. This is the first attempt to determine probabilities and validate it with a robust and effective monitoring system in Darjeeling Himalayas. This study would help in developing an early warning system for regions where the installation of monitoring systems may not be feasible. | Abhirup DIKSHIT Neelima SATYAM | 2019 | Journal of Mountain Science2019，16，4： | 1 |

| 16 | Clinical assessment indicators of postpartum hemorrhage: A systematic review显示文摘Objective: The assessment indicators of postpartum hemorrhage(PPH) were systematically reviewed to explore their relationship with blood loss as an early warning sign to identify potential PPH for prompt intervention.Methods: A systematic literature search of 9 databases was conducted according to inclusion and exclusion criteria using a comprehensive strategy. Strengthening the Reporting of Observational Studies in Epidemiology(STROBE) strategy was chosen as the tool for quality assessment of included studies, and data concerning the basic study characteristics and assessment indicators were extracted.Results: Eleven studies were included in this review. The assessment indicators in different reports covered heart rate, blood pressure, placental and birth canal check, hemoglobin(Hb), hematocrit(HCT),coagulation function tests, hemodynamic parameters and arterial blood gas, but no data on the assessment of postpartum uterine contraction were found. The relationship between indicators and blood loss varies.The overall quality of 9 manuscripts was comparatively high or moderate, and 2 were rated as low.Conclusions: The association between blood loss and clinical symptoms is not conclusive based on the present studies, and specific cut-off points could not be formulated to determine the approximate amount of blood loss. However, some cut-off points can be considered warning signs for the need of advanced interventions, such as heart rate, prothrombin time, and placental implantation. Further research on comprehensive assessment and cut-off points should be performed such that birth attendants can distinguish PPH as early as possible. | Ying Liu Ying Shen Wei Zhu Jing-Bo Qiu Qun Huang Wen-Qin Ye | 2017 | Chinese Nursing Research2017，4，4： | 0 |
| 17 | Validation of the VitalPAC Early Warning Score at the Intermediate Care Unit显示文摘AIM To assess the performance and clinical relevance of the Early Warning Scoring(EWS)system at the Intermediate Care Unit(IMCU).METHODS This cohort study used all the Vital PAC EWS(Vi EWS)scores collected during each nursing shift from 2014through 2016 at the mixed surgical IMCU of an academic teaching hospital.Clinical deterioration defined as transfer to the Intensive Care Unit(ICU)or mortality within 24 h was the primary outcome of interest.RESULTS A total of 9113 aggregated Vi EWS scores were obtained from 2113 admissions.The incidence of the combined outcome was 272(3.0%).The area under the curve of the Vi EWS was 0.72(CI:0.69-0.75).Using a threshold value of six,the sensitivity was 68%with a positive predictive value of 5%and a number needed to trigger(e.g.,false alarms)of 19%.CONCLUSION The Vi EWS at the IMCU has a discriminative performance that is considerably lower than at the hospital ward.The number of false alarms is high,which may result in alarm fatigue.Therefore,use of the Vi EWS in its current form at the IMCU should be reconsidered. | Joost DJ Plate Linda M Peelen Luke PH Leenen Falco Hietbrink | 2018 | World Journal of Critical Care Medicine2018，7，3： | 0 |
