The structurally colored surface of anodic aluminum oxide (AAO) is highly useful for decoration and anti-counterfeiting applications, which are of significance for both scientific and industrial communities. This study presents the first demonstration of the fabrication of an iridescent film of porous AAO on an industrial aluminum alloy substrate, with alternatingly electrodeposited Cu and SiO2 nanoparticles (NPs). A rainbow effect was effectively obtained for the optimized sample with appropriate alternating electrodeposition times. The structure and optical properties of a series of the electrodeposited AAO-based thin film were investigated. The Cu and SiO2 NPs were found to be uniformly deposited into the porous structure of the AAO film, and the alternating electrodeposition repeating twice led to the formation of the optimal AAO-based thin film that exhibited a rainbow effect and superior anti-corrosion performance.
Planetesimal Population Synthesis: Pebble Flux-regulated Planetesimal Formation
Authors: Lenz Christian T. , Klahr Hubert , Birnstiel Tilman
Published: March 2019

We propose an expression for a local planetesimal formation rate proportional to the instantaneous radial pebble flux. The result—a radial planetesimal distribution—can be used as an initial condition to study the formation of planetary embryos. We follow the idea that one needs particle traps to locally enhance the dust-to-gas ratios sufficiently, such that particle gas interactions can no longer prevent planetesimal formation on small scales. The locations of these traps can emerge everywhere in the disk. Their occurrence and lifetime is subject to ongoing research; thus, here they are implemented via free parameters. This enables us to study the influence of the disk properties on the formation of planetesimals, predicting their time-dependent formation rates and the location of primary pebble accretion. We show that large α-values of 0.01 (strong turbulence) prevent the formation of planetesimals in the inner part of the disk, arguing for lower values of around 0.001 (moderate turbulence), at which planetesimals form quickly at all places where they are needed for proto-planets. Planetesimals form as soon as dust has grown to pebbles (mm to dm) and the pebble flux reaches a critical value, which is after a few thousand years at 2–3 au and after a few hundred thousand years at 20–30 au. Planetesimal formation lasts until the pebble supply has decreased below a critical value. The final spatial planetesimal distribution is steeper compared to the initial dust and gas distribution, which helps explain the discrepancy between the minimum mass solar nebula and viscous accretion disks.
Deriving Galaxy Cluster Velocity Anisotropy Profiles from a Joint Analysis of Dynamical and Weak Lensing Data
Authors: Stark Alejo , Miller Christopher J. , Halenka Vitali
Published: March 2019

We present an analytic approach to lift the mass-anisotropy degeneracy in clusters of galaxies by utilizing the line-of-sight velocity dispersion of clustered galaxies jointly with weak lensing inferred masses. More specifically, we solve the spherical Jeans equation by assuming a simple relation between the line-of-sight velocity dispersion and the radial velocity dispersion and recast the Jeans equation as a Bernoulli differential equation that has a well-known analytic solution. We first test our method in cosmological N-body simulations and then derive the anisotropy profiles for 35 archival data galaxy clusters with an average redshift of

. The resulting profiles yield a weighted average global value of

(stat) ±0.15 (sys). This indicates that clustered galaxies tend to globally fall on radially anisotropic orbits. We note that this is the first attempt to derive velocity anisotropy profiles for a cluster sample of this size utilizing joint dynamical and weak lensing data.
Think Global, Act Local: The Influence of Environment Age and Host Mass on Type Ia Supernova Light Curves
Authors: Rose B. M. , Garnavich P. M. , Berg M. A.
Published: March 2019

The reliability of Type Ia Supernovae (SNe Ia) may be limited by the imprint of their galactic origins. To investigate the connection between supernovae and their host characteristics, we developed an improved method to estimate the stellar population age of the host as well as the local environment around the site of the supernova. We use a Bayesian method to estimate the star formation history and mass weighted age of a supernova’s environment by matching observed spectral energy distributions to a synthesized stellar population. Applying this age estimator to both the photometrically and spectroscopically classified Sloan Digital Sky Survey II supernovae (N = 103), we find a 0.114 ± 0.039 mag “step” in the average Hubble residual at a stellar age of ∼8 Gyr; it is nearly twice the size of the currently popular mass step. We then apply a principal component analysis on the SALT2 parameters, host stellar mass, and local environment age. We find that a new parameter, PC1, consisting of a linear combination of stretch, host stellar mass, and local age, shows a very significant (4.7σ) correlation with Hubble residuals. There is a much broader range of PC1 values found in the Hubble flow sample when compared with the Cepheid calibration galaxies. These samples have mildly statistically different average PC1 values, at ∼2.5σ, resulting in at most a 1.3% reduction in the evaluation of H
0. Despite accounting for the highly significant trend in SN Ia Hubble residuals, there remains a 9% discrepancy between the most recent precision estimates of H
0 using SN Ia and the CMB.
Search for Gravitational Lensing Signatures in LIGO-Virgo Binary Black Hole Events
Authors: Hannuksela O. A. , Haris K. , Ng K. K. Y. , Kumar S. , Mehta A. K. , Keitel D. , Li T. G. F. , Ajith P.
Published: March 2019

We search for signatures of gravitational lensing in the binary black hole events detected by Advanced LIGO and Virgo during their first two observational runs. In particular, we look for three effects: (1) evidence of lensing magnification in the individual signals due to galaxy lenses, (2) evidence of multiple images due to strong lensing by galaxies, and (3) evidence of wave optics effects due to point-mass lens. We find no compelling evidence of any of these signatures in the observed gravitational wave signals. However, as the sensitivities of gravitational wave detectors improve in the future, detecting lensed events may become quite likely.

Authors: Bedenko Sergey V. , Knyshev Vladimir V. , Kuznetsova Mariya Ye. , Lutsik Igor O. , Shamanin Igor V.
Published: March 2019

A computational study has been performed for various options of the thorium reactor core loading. Neutronic studies of fuel have been conducted, its isotopic composition has been calculated, and the alpha emitters and the sources of neutron and photon radiation in the microencapsulated nuclear fuel have been analyzed. The studies had the purpose of developing the methodology used to estimate the radiation characteristics of nuclear fuel with a complex inner structure. Emphasis is placed on calculating the quantitative and spectral composition of the neutrons formed as the result of (a, n) reactions on small- and average-mass nuclei. The ratio of the quantity of the neutrons resulting from the (a, n) reactions to the quantity of the neutrons formed as the result of spontaneous fission has been calculated for fuel with heterogeneous and homogeneous arrangements of fissionable and structural elements. The developed tools will make it possible to estimate the neutron radiation dose, to revise the traditional fresh and spent fuel handling procedures, and to estimate, using the Rossi alpha method, the neutron multiplication factor in deeply subcritical systems. The neutron yield and spectrum were calculated using an analytical model and verified codes such as WIMS-D5B, ORIGEN-APP, SOURCES-4C and SRIM-2013.

Published: March 2019

The article presents a description and some illustrative results of the application of two optimization models for a two-component nuclear energy system consisting of thermal and fast reactors in a closed nuclear fuel cycle. These models correspond to two possible options of developing Russian nuclear energy system, which are discussed in the expert community: (1) thermal and fast reactors utilizing uranium and mixed oxide fuel, (2) thermal reactors utilizing uranium oxide fuel and fast reactors utilizing mixed nitride uranium-plutonium fuel. The optimization models elaborated using the IAEA MESSAGE energy planning tool make it possible not only to optimize the nuclear energy system structure according to the economic criterion, taking into account resource and infrastructural constraints, but also to be used as a basis for developing multi-objective, stochastic and robust optimization models of a two-component nuclear energy system. These models were elaborated in full compliance with the recommendations of the IAEA’s PESS and INPRO sections, regarding the specification of nuclear energy systems in MESSAGE. The study is based on publications of experts from NRC “Kurchatov Institute”, JSC “SSC RF-IPPE”, ITCP “Proryv”, JSC “NIKIET”. The presented results demonstrate the characteristic structural features of a two-component nuclear energy system for conservative assumptions in order to illustrate the capabilities of the developed optimization models. Consideration is also given to the economic feasibility of a technologically diversified nuclear energy structure providing the possibility of forming on its base a robust system in the future. It has been demonstrated that given the current uncertainties in the costs of nuclear fuel cycle services and reactor technologies, it is impossible at the moment to make a reasonable conclusion regarding the greatest attractiveness of a particular option in terms of the economic performance.
Investigation of the small break conditions in the primary circuit of a VVER-1000 reactor*
Authors: Belozerov Vladimir I. , Zhuk Mikhail M. , Terekhova Anna M.
Published: March 2019

Modes with violation of the reactor plant cooling conditions on the primary circuit side of a VVER reactor were simulated using the TRAC-PD2 and Open FOAM thermohydraulic codes (TRAC-PD2 1981, OpenFOAM User Guide Version 1.6. 2009, OpenFOAM Programmer’s Guide Version 1.6. 2009) based on energy and mass conservation equations for the three-dimensional unsteady flow of a two-phase mixture. Coupled simulation of the dynamics of neutronic and thermohydraulic processes (TRAC-PD2 1981, OpenFOAM User Guide Version 1.6. 2009, OpenFOAM Programmer’s Guide Version 1.6. 2009, Bolshagin et al. 2009, Galanin 1971, Weinberg and Wigner 1961, Ovchinnikov and Semenov 1988, Report LA-UR-03-1987) aims to improve the qualitative understanding and the quantitative presentation of their effects on safety.

Investigating these modes using the above thermohydraulic codes makes it possible to analyze the course of transients and certain emergency processes without using the industrial testing method, this providing the basis for solving the problems of ensuring the reliability, operational safety and efficiency of nuclear power plants.

A modern nuclear reactor is a complex system studying and calculating which requires more than the use of simple theoretical models. Thermohydraulic calculations are an essential part of most engineering and technological development works in nuclear power. Since, in conditions of an NPP, no technologically conventional way can be used to verify and update the results and findings of an a priori analysis on the basis of commercial tests, investigations based on codes are used in some cases as the tools to study and predict the parameters of thermohydraulic processes in the reactor’s circulation circuit.

The main purpose of the study is to calculate and investigate, based on codes, modes with violation of the reactor plant cooling conditions on the primary circuit side of a VVER reactor in order to determine if calculated parameters conform to the acceptance criteria established by regulatory documents.

Benefits of COMMUNITY MEETINGS in the Corporate Setting After the Suicide of a Coworker
Authors: Clements Paul T , DeRanieri Joseph T , Fay-Hillier Theresa M , Henry Gloria C
Published: March 2019

ABSTRACT

When an employee commits suicide, his or her coworkers are confronted unexpectedly with issues related to the sudden traumatic death. Being inundated with questions, grappling with acceptance of the loss, and exploring how this could have happened are factors that can complicate the bereavement process and delay a return to workplace homeostasis. Understanding the dynamics and issues related to grief and bereavement after sudden traumatic death potentially can accelerate the recovery process and promote restoration of workforce normalcy for employees and organizations. This can be significantly important to corporate managers and administrators who must maintain ongoing productivity despite such disruption, while promoting adaptive coping for their employees.

Authors: King Beth M. , Linette Donna , Donohue-Smith Maureen , Wolf Zane Robinson
Published: March 2019

Patients admitted to psychiatric acute care settings benefit from interactions and caring relationships with hospital staff. The current study describes the association between patients' perceptions of nurse caring and their satisfaction with care at an inpatient psychiatric–mental health unit. The relationship between patients' perceptions of nurse caring and two measures of satisfaction with care were explored. A convenience sample of patients (
N
= 169) completed the Caring Behaviors Inventory-16 and Client Satisfaction Survey. Data were collected at the time of discharge from the hospital. The associations between perceived nurse caring and satisfaction with care and overall satisfaction with care resulted in strong, positive, statistically significant correlations. Treating patient information confidentially and giving treatments and medications on time were highly ranked, along with feeling safe during the hospitalization and satisfaction with nursing care. Additional research on patients' perception of nurse caring and satisfaction with care is needed. [

Authors: Adeniran Janelle Fassbender , Sophie Raafay , Adhi Mehreen , Ramasubramanian Aparna
Published: March 2019

BACKGROUND AND OBJECTIVE:

Detection of early vascular changes observed on optical coherence tomography angiography (OCTA) in children who have received external beam radiation and are at risk of developing radiation retinopathy (RR).

PATIENTS AND METHODS:

Eleven pediatric patients (20 eyes) with history of irradiation and nine healthy subjects (14 eyes) were retrospectively studied after dilated fundus exam and imaging.

RESULTS:

Four eyes of three patients had clinical RR. Eyes with radiation exposure but no RR had worse vision (no RR: logMAR 0.09 ± 0.14, Snellen 20/25) than controls (logMAR 0.01 ± 0.03, Snellen 20/21;
P
= .04) and increased superficial foveal avascular zone (FAZ) area (radiation: 0.31 ± 0.15 vs. control: 0.18 ± 0.10;
P
= .005). Eyes with RR had worse vision (RR: logMAR 0.34 ± 0.31, Snellen 20/44) than eyes with no RR (
P
= .001) and had increased deep FAZ (RR: 1.23 ± 0.40 vs. no RR: 0.68 ± 0.25;
P
= .01), but similar superficial FAZ (RR: 0.44 ± 0.28 vs. no RR: 0.31 ± 0.15;
P
= .42).

CONCLUSIONS:

Eyes with mildly decreased vision but no RR show superficial but not deep plexus changes. Eyes with RR have both superficial and deep plexus changes.

Modified Cow-Hitch Suture for Repositioning of Subluxated Scleral-Fixated Rigid Intraocular Lens
Authors: Ma I-Hsin , Tsai Chia-Ying , Yang Chung-May , Lai Tso-Ting
Published: March 2019

BACKGROUND AND OBJECTIVE:

To describe a new technique for repositioning a subluxated scleral-fixated rigid intraocular lens (IOL).

PATIENTS AND METHODS:

The authors present a modified intraocular threading technique to tie a cow-hitch knot around the eyelet on the dislocated haptic of a scleral-fixated rigid IOL. This technique uses three small corneal incisions to eliminate the need for IOL externalization and minimized the size and number of wounds.

RESULTS:

Three consecutive cases of subluxated haptics in two patients underwent this procedure. Postoperative IOL centration and alignment were satisfactory without tilt. No surgical-related complication was observed 1 year after surgery.

CONCLUSION:

A rigid IOL could be repositioned to a desired axis and centration via this modified cow-hitch technique, with better IOL support as compared with a single tie.

Published: March 2019

Managing knowledge has become a critical aspect of the contemporary business landscape. In addition, business no longer has profit as the sole purpose of their existence. Therefore, there has been growing impetus for socially and environmentally conscious business actions. The present article takes a dimensional view of the process of knowledge management. The authors disaggregate the process along three dimensions- knowledge acquisition, knowledge dissemination and responsiveness to knowledge and investigate their impact on sustainable business performance. In addition, this article assesses the moderating role of empowering leadership in the relationship between knowledge management components. Among various leadership behaviors, empowering leadership has assumed critical significance owing to growing chorus on providing autonomy and empowerment to employees. This article tests the hypotheses on data collected from manufacturing firms in India. The results demonstrate a positive relationship between dimensions of knowledge management, as well as positive moderation by empowering leadership. Further, the authors discuss implications.

Published: March 2019

Objective: To report our single-center experience in terms of patient clinical characteristics, treatment outcomes, and chemotherapy-related toxicities in patients with low-risk gestational trophoblastic neoplasia (GTN). Materials and Methods: A retrospective cross-sectional study (2008–2013) was conducted at a tertiary health-care hospital in Saudi Arabia. Forty-four (n = 44) patients met the inclusion criteria for low-risk GTN. Methotrexate (MTX) was administered in a 5-day regimen: 0.3–0.5mg/kg intravenously (IV) daily for 5 days every 2 weeks (maximum 25mg per dose). Actinomycin D (ActD) was administered 1.25mg/m2 pulsed IV every 2 weeks. Results: The majority of patients had molar pregnancy as the antecedent event (86%), developed GTN within the first 4 months after the initial evacuation (93.2%), had human chorionic gonadotropin levels between 1,000 and 10,000 mIU/dL (36.3%), and had the World Health Organization prognostic scores from 0 to 2 (48.7%). Only 38 patients accepted treatment with chemotherapy. A total of 37 patients received first-line MTX; 34 patients of them achieved complete remission (CR, 92%). The three patients who developed MTX resistance were salvaged with sequential ActD and all achieved CR of 100%. Only one patient received first-line ActD and achieved CR. The overall survival as well as cure rate for all patients with low-risk GTN was 100%. No patient developed MTX-related hepatic toxicity or ActD-related blister formation. No severe adverse effects occurred. Conclusion: Our 5-day IV MTX regimen was highly effective in treating patients with low-risk GTN, with CR rate of 92% and no severe toxicity. Primary and sequential ActD therapy appears to be very effective.
Clinical Utility of Platelet Count as a Prognostic Marker for Melioidosis
Authors: Kirby Philippa , Smith Simon , Ward Linda , Hanson Josh , Currie Bart J.
Published: March 2019

Thromobocytopenia predicts mortality in patients with melioidosis in Thailand. We analyzed platelet counts in two large cohorts of melioidosis patients in tropical northern Australia to assess utility in a different clinical setting. Admission platelet counts were compared between subgroups of patients with different clinical outcomes. Patients with more severe disease (indicated by bacteremia, septic shock, and death) had significantly lower platelet counts than those with less severe disease. Logistic regression analysis was carried out for potential predictors of mortality among various clinical parameters, and platelet count was shown to be an independent predictor of mortality. Furthermore, in patients critically ill with melioidosis, an increasing platelet count after admission was associated with a significantly greater chance of survival. However, given that most patients with severe disease still had platelet counts within the normal range, platelet count is not a useful biomarker for predicting the severity of melioidosis in a clinical context.
Experiences of Civil Certification of Multi-Core Processing Systems in Commercial and Military Avionics, Integration Activities, and Analysis
Authors: Tiedeman Harold Glenn , Parkinson Paul
Published: March 2019

Avionics systems are currently undergoing a transition from single core processor architectures to multi-core processor architectures. This transition enables significant advantages in reduction in size, weight, power (SWaP) and cost. However, avionics hardware and software certification policies and guidance are evolving as research and experience is gained with multi-core processor architectures. The unique challenges of using multi-core processors in certified avionics will be discussed. The requirements for a virtualization platform supporting multiple real-time operating system (RTOS) partitions on a multi-core processor used in safety-critical avionics systems are defined, including the ability to support multiple design assurance levels (DAL) on multiple cores, fault isolation and containment, static configuration as per ARINC 653, role-based development as per DO-297, and robust partitioning to reduce cost of incremental certification. The paper will present a collaborative approach undertaken by a leading avionics system supplier and a leading safety-critical commercial-off-the-shelf (COTS) RTOS supplier in the development of a multi-core real-time system with DO-178C DAL A software and DO-254 DAL A hardware safety certification on an FAA Program of Record (PoR). The approach taken to comply with FAA CAST-32A objectives will be presented. Particular focus is provided for integration activities and program specific analysis performed by the IMA application developer and integrator to guarantee determinism in the deployed system. Using the approach defined under the PoR, the application developer performs activities including foot-printing under worst-case execution time (WCET) loads and application of numerical methods to predict interference effects. The IMA integrator uses this data to define a performance restricted environment (PRE) and uses WCET verification in the PRE. Tools, analysis methods, and sample results will be presented. The method to capture results is discussed. Finally the paper includes lessons learned during the program.

Health protection planning for extreme weather events and natural disasters
Authors: Papadakis, PhD Giorgos , Chalabi, PhD Zaid , Khare, MSc Swarna , Bone, MBChB, MSc Angie , Hajat, PhD Shakoor , Kovats, PhD Sari
Published: March 2019

Objective: There is a need to develop cost-effective methods to support public health policy makers plan ahead and make robust decisions on protective measures to safeguard against severe impacts of extreme weather events and natural disasters in the future, given competing demands on the social and healthcare resources, large uncertainty associated with extreme events and their impacts, and the opportunity costs associated with making ineffective decisions.Design: The authors combine a physics-based method known as nonextensive statistical mechanics for modeling the probability distribution of systems or processes exhibiting extreme behavior, with a decision-analytical method known as partitioned multiobjective risk method to determine the optimal decision option when planning for potential extreme events.Results: The method is illustrated using a simple hypothetical example. It is shown that partitioning the exceedance probability distribution of health impact into three ranges (low severity/high exceedance probability, moderate severity/medium exceedance probability, and high severity/low exceedance probability) leads to the correct estimation of the conditional expected impact in each range. Multiobjective optimization is used to determine the optimal decision option based on the perspective of the policy maker.Conclusion: This method constitutes a robust generic framework for the quantification of impacts and supporting decision-making under scenarios of extreme and catastrophic health risks.
Have you “CORED” lately? A comprehensive operating room evacuation drill
Authors: Hart, MD Alexander , Femino, HEM Meg , Sears, HEM Bryan , Wolberg, BA Adam , Cook, MD, FACS Charles H. , Gupta, MD, FACS Alok
Published: March 2019

Introduction: Crises in the operating room (OR) are uncommon events that require an expeditious response from all providers to minimize morbidity and mortality to both patients and staff. Evacuation during a surgical procedure presents a unique challenge. There is a paucity of data on the ideal response, ideal times, and training needs for hospital staff.Methods: The authors herein describe a full-scale simulation exercise of the emergent mid-procedure evacuation of seven ORs.Results: Median time to evacuate from the OR and reach the Post-Anesthesia Care Unit safety point was 3:50 minutes (range, 1:22 minutes to 6:00 minutes). Multiple lessons were learned from direct observation, post-drill debrief, and post-drill survey of participants.Conclusions: Emergent mid-procedure evacuation of ORs can be expeditious if needed. Critical themes in leadership, communication, and coordination of care were discovered. Surgeons, anesthesiologists, and OR staff should consider performing an OR evacuation drill to improve their local efficacy and efficiency in emergent OR evacuation.

An intergenerational art program as a means to decrease passive behaviors in patients with dementia
Authors: Brownell, PhD, RN Catherine A.
Published: March 2019

This study evaluated the impact of participation in an intergenerational art program on the cognitive and emotional responses of adults with dementia. A secondary purpose was to capitalize on existing resources to engage the community in a rural residential care center. The responses of residents participating in a structured art program facilitated by high school students were compared with those offered an individual art activity. Four measures of cognitive, emotional, and behavioral responses were evaluated. No significant differences were found between the two groups; however, participation in the structured art project increased each session. Residents able to understand and respond to the art activity were likely to become engaged and show interest. Findings suggest that participation in activities at an appropriate functional level may penetrate the apathy and decrease the isolation seen with passive behaviors. Qualitative data revealed positive attitude changes among the high school students regarding older adults, nursing homes, and working with people with dementia.

The aim of this study was to assess perception of activity and social context scales1 of adolescent substance abusers following participation in a physical activity intervention during residential drug treatment. The sample was assessed on entry to treatment, on completion of treatment; six weeks postresidential treatment and six months after treatment using mean, standard deviation, and t-tests. In general, the overall mean scores for perception of social context increased from entry to completion of the treatment program, decreased six weeks post-treatment, and increased when six months in aftercare. Some significant difference was recorded between entry to treatment and six weeks post-treatment (p = 0.04). The results relating to perception of activity increased from entry to completion of the treatment program, increased at six weeks post-treatment, and decreased to six months in aftercare. Some significant differences were recorded between entry and six weeks post-treatment (p = 0.02), between completion of treatment and six months in aftercare (p = 0.03), and between six weeks post-treatment and six months in aftercare (p = 0.05). This research hoped to illustrate the potential of physical activity as alternative leisure pursuit following addiction treatment to help prevent relapse for adolescent substance abusers by reducing contact with other users and providing a healthy and positive social outlet.

Authors: Adams, MS, CTRS, C-IAYT Emilie V. , Townsend, PhD, CTRS Jasmine
Published: March 2019

Schizophrenia spectrum disorders (SSDs) are a group of mental illnesses characterized by hallucinations, delusions, disorganized thought; they are often accompanied by cognitive dysfunction, social skills deficits, and low volition. This article reviews the extant literature on the efficacy of using yoga as an adjunct therapy to supplement standard pharmacotherapy and psychotherapy in the treatment and management of SSD. The 16 studies reviewed indicate yoga may be an effective intervention for increasing global cognitive functioning, decreasing psychotic symptoms, and improving quality of life for clients with SSD. Recommendations for integration of yoga into a Recreation Therapy program are outlined.

An updated hazard vulnerability analysis: A value-based model
Authors: Phelps, JD, MPH, CEM, CBCP Scot
Published: March 2019

Traditional hazard vulnerability analysis (HVA) looks at probability and impact to determine risk. The results are often graphically displayed in an XY chart, and mitigation priorities are determined by risk ranking alone. This model is not sufficient, because it does not consider the cost of mitigation. The updated HVA looks at value, in which the traditional XY chart is expanded to a cube model in which the Z axis reflects cost. In a typical hospital HVA, where there may be over 50 different potential events, determining proximity to the perfect value point (high probability, high impact, low cost) allows a better ranking system when allocating scarce mitigation dollars.

The tsunami of December 26, 2004, can be described as one of the worst disasters medical systems have ever had to face. This paper will describe the geophysical properties of tsunamis and their disastrous impact on human beings and infrastructure. Finally, we will present three different modes of response to the tsunami that were present in different provinces in Thailand. These three modes represent different strategies of disaster management, and analyzing each will help to begin understanding how best to respond to the next large-scale natural disaster.
Network-centric emergency response: The challenges of training for a new command and control paradigm
Authors: Stanovich, USMCR Lt. Col. Mark
Published: March 2019

The last two decades have seen technological innovations that have revolutionized the collection and transfer of information, permitting access to and dissemination of massive amounts of data with unprecedented speed and efficiency. These innovations have been incorporated into virtually every aspect of modern society, from personal communications, to commercial and business processes, to governmental function and military operations. The concept of network-centric warfare (NCW) grew out of these new capabilities and has been a prominent topic in strategic and operational discussions in the US military since the late 1990s.In recent years, the concepts behind NCW have been increasingly applied to emergency response, particularly as responders prepare for an increasingly complex threat spectrum in a post-9/11 world. As emergency responders adopt the technological innovations and organizational concepts that enable network-centric operations, attention should be paid to the lessons learned by the US armed forces in the application of the network-centric approach to war-fighting. Emergency operations centers (EOCs), incident command centers (ICCs), and field personnel will require extensive training and experimentation to sort out the impact of this new technology. They must develop protocols and procedures to leverage maximum advantage, while avoiding the undesirable and damaging effects of that technology improperly applied. Because most emergency response organizations lack the vast training resources of the US military, they must be innovative and adaptable in taking advantage of every opportunity to train their personnel in the assimilation of this new technology.

Emergency logistics planning and disaster preparedness
Authors: Kapucu, PhD Naim
Published: March 2019

Emergency management is often evaluated and improved after a disaster, especially in the realm of preparedness. This article discusses the importance of logistics planning and operation as it relates to preparedness. The selection of field logistics sites, such as staging areas, prior to the occurrence of a natural or man-made disaster is a crucial step in emergency management planning. Selection can be aided and kept consistent by pre-identifying state- and countylevel guidelines for staging areas.

Background: The Center for Devices and Radiological Health, Food and Drug Administration (FDA) launched a collaborative initiative with Centers for Disease Control and Prevention (CDC) to gain a better understanding of ventilators that are used during national emergencies. This initiative was intended to test reliability of ventilator devices stored long term in the CDC Strategic National Stockpile (SNS) and also used by the Department of Defense. These ventilators are intended to be used by trained operators to provide ventilatory support to adult and pediatric populations under diverse environmental conditions. The authors evaluated device performance and possible effects of long-term storage.Methods: Three SNS ventilator models: Impact Uni-Vent 754 Eagle™, Covidien (Puritan Bennett) LP10, and CareFusion LTV 1200 were used in this study. A total of 36 ventilators, 12 per model, were evaluated for performance in simulated adult populations using a test lung. The parameters evaluated included battery charge status and capability, battery longevity, positive end expiratory pressure consistency, device performance on AC and DC (battery) power, and device durability testing.Results: The out-of-the-box run time was equal to or higher than the manufacturer’s specifications for fully charged batteries for all ventilators except 58 percent of the Impact 754 ventilators. No significant ventilator performance issues were observed in terms of tidal volume consistency, proximal pressure, oxygen consumption, and a 2000-hour run test in LP10 models.Conclusions: These findings provide information about the long-term storage of ventilators that have regular maintenance, and their ability to perform reliably during a public health emergency.

Introduction

Recently introduced microUSB ultrasound probe, which can be connected to personal mobile device constitutes a new class of diagnostic pocket size imaging devices (PSID).The aim of this study was to assess the feasibility and clinical utility of real-time tele-echocardiography with the use such device.

Material and methods

The study group comprised 30 patients (18 men and 12 women; mean age: 54 ±14 years; mean BMI: 27 ±6 kg/m2), admitted to various hospital departments (infectious diseases, internal medicine and cardiology). All patients underwent focused echocardiographic examination performed by an inexperienced operator using PSID and collaborating remotely in real-time with cardiologist by means of tele-consultation. Before commencing the examination, the operators underwent one hour training in use of the PSID.

Results

In most of patients PSID imaging provided sufficient diagnostic image quality. The dimensions of left ventricle, left atrium and the aorta obtained during the this examination showed good correlation with standard echocardiography (r = 0.89, r = 0.82, r = 0.92 respectively), but the correlation for TAPSE measurements was less pronounced (r = 0.52). The agreement in detection of pathologies (wall motion abnormalities, morphological and functional valvular abnormalities) between the tele-echocardiography and standard echocardiographic examination was good to very good ( ranged from 0.648 to 0.823).

Conclusions

Pocket size imaging devices allows an inexperienced operator to perform a focused echocardiographic examination under a remote supervision of an experienced cardiologist. The introduction of new technology in the form of PSID with tele-echocardiography feature can revolutionize access to this imaging technique.
