2018-05-01

Hepatitis C virus (HCV) infection poses significant adverse health effects. Improper use of vials, needles, syringes, intravenous bags, tubing, and connectors for injections and infusions is a current preventable cause of iatrogenic HCV transmission. Numerous cases have demonstrated the need for continued vigilance and the widespread nature of this iatrogenic infection risk across a variety of medical practice settings in the United States. Failure to implement the evidence-based Centers for Disease Control and Prevention (CDC) infection prevention guidelines exposes patients to preventable harm. The guidelines establish the requirement to notify patients in cases of suspected virus transmission, as well as to screen those patients who would not otherwise have been at risk for HCV seroconversion and other bloodborne pathogens. Legal and regulatory ramifications, including state, criminal, and tort laws, hold physicians and other health care professionals accountable to use safe injection practices. This article reviews the major health risks of HCV infection, significant effects of iatrogenic infection transmission, CDC guidelines for safe injection practices, and legal regulations and ramifications designed to promote safe injection practices.

The Dutch government considers the transition process to be necessary and stimulates investments in energy innovations in the built environment. This innovation effort is the programme 'Energy Leap' (Energiesprong), which is being carried out by the Steering Group Experimental Housing (SEV) on behalf of the Dutch Ministry of the Interior and Kingdom Relations (BZK). The programme is derived from the Innovation Agenda for Energy in the Built Environment. The SEV 'Energy Leap' programme aims to make a substantial contribution to the conditions under which the energy transition can be achieved effectively. In this basic plan, it is explained how the market can arrive at this, and which activities will be supported, set up and/or implemented by Energy Leap.

Hybrid chernoff tau-leap

KAUST Repository

Moraes, Alvaro

2014-01-01

Markovian pure jump processes model a wide range of phenomena, including chemical reactions at the molecular level, dynamics of wireless communication networks, and the spread of epidemic diseases in small populations. There exist algorithms such as Gillespie\\'s stochastic simulation algorithm (SSA) and Anderson\\'s modified next reaction method (MNRM) that simulate a single path with the exact distribution of the process, but this can be time consuming when many reactions take place during a short time interval. Gillespie\\'s approximated tau-leap method, on the other hand, can be used to reduce computational time, but it may lead to nonphysical values due to a positive one-step exit probability, and it also introduces a time discretization error. Here, we present a novel hybrid algorithm for simulating individual paths which adaptively switches between the SSA and the tau-leap method. The switching strategy is based on a comparison of the expected interarrival time of the SSA and an adaptive time step derived from a Chernoff-type bound for the one-step exit probability. Because this bound is nonasymptotic, we do not need to make any distributional approximation for the tau-leap increments. This hybrid method allows us (i) to control the global exit probability of any simulated path and (ii) to obtain accurate and computable estimates of the expected value of any smooth observable of the process with minimal computational work. We present numerical examples that illustrate the performance of the proposed method. © 2014 Society for Industrial and Applied Mathematics.

This study aims at: examining if leadership style and unit climate predict safety climate; and testing the direct, indirect, and total effect of leadership style, unit climate, and safety climate on nurses' safe medication practices. The Institute of Medicine and nursing scholars propose that safety climate is a prerequisite to safety practices. However, there is limited empirical evidence about factors contributing to the development of safety climate and about the association with nurses' safe medication practices. This cross-sectional study used survey data from 246 RNs working in a Magnet® hospital. Leadership style and unit climate predicted 20% to 50% of variance on all safety climate dimensions. Model testing revealed the indirect impact of leadership style and unit climate on nurses' safe medication practices. Our hypothesized model explained small amount of the variance on nurses' safe medication practices. This finding suggests that nurses' safe medication practices are influenced by multiple contextual and personal factors that should be further examined.

Does LEAP change the screening paradigm for food allergy in infants with eczema?

Science.gov (United States)

Allen, K J; Koplin, J J

2016-01-01

The LEAP randomized controlled trial provides the first direct evidence that delayed introduction of peanut in an infant's diet significantly increases the risk of peanut allergy. However, as often is the case in ground-breaking research, the LEAP study raises almost as many questions as it resolves. Although the quality of design and excellence in study execution is unquestioned, the particular difficulty this study raises is how to generalize results from a trial of high-risk infants, which screened infants for the presence of peanut allergy prior to peanut introduction, to the general population. Although many existing infant feeding guidelines already allow for the introduction of allergenic foods from 4 to 6 months of age irrespective of co-existent risk factors for peanut allergy, these will now need to be revised to more strongly state that avoidance may be harmful. Interim guidelines have already been published which incorporate these recommendations. However, the question as to how to achieve timely introduction of peanut into an infant's diet in a safe and cost-effective way, particularly in high-risk infants, remains unresolved. © 2015 John Wiley & Sons Ltd.

Thousands of operations involving the use of radioactive substances will end during the current century. While there is considerable regulatory experience in the 'front end' of the regulatory system for practices, the experience at the back end is more limited as fewer practices have actually been terminated. When a practice is terminated because the facility has reached the end of its useful life, action has to betaken to ensure the safe shutdown of the facility and allow the removal of regulatory controls. There are many issues involved in the safe termination of practices. These include setting criteria for the release of material and sites from regulatory control; determining the suitability of the various options for decommissioning nuclear facilities, managing the waste and material released from control (recycling, reuse or disposal), and the eventual remediation of the site. Some countries have put in place regulatory infrastructures and have developed programmes to manage the associated decommissioning and remediation activities. Other countries are at the stage of assessing what is involved in terminating such practices. The purpose of this Conference is to foster an information exchange on the safe an orderly termination of practices that involve the use of radioactive substances, including both decommissioning and environmental remediation, and to promote improved coherence internationally on strategies and criteria for the safe termination of practices.

LEAP: biomarker inference through learning and evaluating association patterns.

Science.gov (United States)

Jiang, Xia; Neapolitan, Richard E

2015-03-01

Single nucleotide polymorphism (SNP) high-dimensional datasets are available from Genome Wide Association Studies (GWAS). Such data provide researchers opportunities to investigate the complex genetic basis of diseases. Much of genetic risk might be due to undiscovered epistatic interactions, which are interactions in which combination of several genes affect disease. Research aimed at discovering interacting SNPs from GWAS datasets proceeded in two directions. First, tools were developed to evaluate candidate interactions. Second, algorithms were developed to search over the space of candidate interactions. Another problem when learning interacting SNPs, which has not received much attention, is evaluating how likely it is that the learned SNPs are associated with the disease. A complete system should provide this information as well. We develop such a system. Our system, called LEAP, includes a new heuristic search algorithm for learning interacting SNPs, and a Bayesian network based algorithm for computing the probability of their association. We evaluated the performance of LEAP using 100 1,000-SNP simulated datasets, each of which contains 15 SNPs involved in interactions. When learning interacting SNPs from these datasets, LEAP outperformed seven others methods. Furthermore, only SNPs involved in interactions were found to be probable. We also used LEAP to analyze real Alzheimer's disease and breast cancer GWAS datasets. We obtained interesting and new results from the Alzheimer's dataset, but limited results from the breast cancer dataset. We conclude that our results support that LEAP is a useful tool for extracting candidate interacting SNPs from high-dimensional datasets and determining their probability. © 2015 The Authors. *Genetic Epidemiology published by Wiley Periodicals, Inc.

Avoiding negative populations in explicit Poisson tau-leaping.

Science.gov (United States)

Cao, Yang; Gillespie, Daniel T; Petzold, Linda R

2005-08-01

The explicit tau-leaping procedure attempts to speed up the stochastic simulation of a chemically reacting system by approximating the number of firings of each reaction channel during a chosen time increment tau as a Poisson random variable. Since the Poisson random variable can have arbitrarily large sample values, there is always the possibility that this procedure will cause one or more reaction channels to fire so many times during tau that the population of some reactant species will be driven negative. Two recent papers have shown how that unacceptable occurrence can be avoided by replacing the Poisson random variables with binomial random variables, whose values are naturally bounded. This paper describes a modified Poisson tau-leaping procedure that also avoids negative populations, but is easier to implement than the binomial procedure. The new Poisson procedure also introduces a second control parameter, whose value essentially dials the procedure from the original Poisson tau-leaping at one extreme to the exact stochastic simulation algorithm at the other; therefore, the modified Poisson procedure will generally be more accurate than the original Poisson procedure.

Study protocol: translating and implementing psychosocial interventions in aged home care the lifestyle engagement activity program (LEAP) for life

Science.gov (United States)

2013-01-01

Background Tailored psychosocial activity-based interventions have been shown to improve mood, behaviour and quality of life for nursing home residents. Occupational therapist delivered activity programs have shown benefits when delivered in home care settings for people with dementia. The primary aim of this study is to evaluate the effect of LEAP (Lifestyle Engagement Activity Program) for Life, a training and practice change program on the engagement of home care clients by care workers. Secondary aims are to evaluate the impact of the program on changes in client mood and behaviour. Methods/design The 12 month LEAP program has three components: 1) engaging site management and care staff in the program; 2) employing a LEAP champion one day a week to support program activities; 3) delivering an evidence-based training program to care staff. Specifically, case managers will be trained and supported to set meaningful social or recreational goals with clients and incorporate these into care plans. Care workers will be trained in and encouraged to practise good communication, promote client independence and choice, and tailor meaningful activities using Montessori principles, reminiscence, music, physical activity and play. LEAP Champions will be given information about theories of organisational change and trained in interpersonal skills required for their role. LEAP will be evaluated in five home care sites including two that service ethnic minority groups. A quasi experimental design will be used with evaluation data collected four times: 6-months prior to program commencement; at the start of the program; and then after 6 and 12 months. Mixed effect models will enable comparison of change in outcomes for the periods before and during the program. The primary outcome measure is client engagement. Secondary outcomes for clients are satisfaction with care, dysphoria/depression, loneliness, apathy and agitation; and work satisfaction for care workers. A process

This report describes progress made at ORNL toward development and demonstration of a methodology for evaluating energy-economic modeling codes and important results derived from these codes. To bolster traditional evaluation methods with more-quantitative procedures of interest to the Energy Information Administration, ORNL is applying sensitivity theory as part of a comprehensive effort to quantify the importance of various data and model parameters to the key results that are of interest. The Long-Term Energy Analysis Program (LEAP) was chosen as the initial focus for the research. LEAP is an energy-economy model which resides in the Long-Term Energy Analysis Division (LTEAD) of the Integrative Analysis Group in the Office of Applied Analysis, EIA. LTEAD developed Model 22C of LEAP for two reasons: (1) to prepare projections through the year 2020, which were needed for the 1978 EIA Annual Report to Congress and (2) to develop a base for analyses of specific options for Federal action. LEAP Model 22C and its uses are described to provide the background for this interim description of the model evaluation effort at ORNL. 19 figures, 10 tables.

Safe practices and financial considerations in using oral chemotherapeutic agents.

Science.gov (United States)

Bartel, Sylvia B

2007-05-01

Safe handling practices and financial concerns associated with oral chemotherapy in non-traditional settings are discussed. Oral chemotherapy may pose a risk to patients because of a narrow therapeutic index, complex dosing regimen, dispensing by community pharmacists without prescription order review by an oncology pharmacist or nurse, or self-administration in the home or another nontraditional setting, where patient monitoring is infrequent. Errors in prescribing, dispensing, and administration and patient or caregiver misunderstandings are potential problems with the use of oral chemotherapy that need to be addressed when developing safe practices. Changes in Medicare pharmaceutical reimbursement rates and rules need to be monitored because they have the potential to affect patient care and outcomes. Patient assistance programs and advocacy groups can help alleviate financial concerns associated with oral chemotherapy. Consensus guidelines specific to safe handling of oral chemotherapy in the home or other nontraditional setting need to be developed. Also, healthcare providers must understand reimbursement and provide direction to patients when patient assistance programs or advocacy groups can assist with the financial challenges of oral chemotherapy.

Currently, cross-sectional imaging viewing is used in routine practice whereas the surgical procedure requires physical contact with an interface (mouse or touch-sensitive screen). This type of contact results in a risk of lack of aseptic control and causes loss of time. The recent appearance of devices such as the Leap Motion(®) (Leap Motion society, San Francisco, USA) a sensor which enables to interact with the computer without any physical contact is of major interest in the field of surgery. However, its configuration and ergonomics produce key challenges in order to adapt to the practitioner's requirements, the imaging software as well as the surgical environment. This article aims to suggest an easy configuration of the Leap Motion(®) in neurosurgery on a PC for an optimized utilization with Carestream(®) Vue PACS v11.3.4 (Carestream Health, Inc., Rochester, USA) using a plug-in (to download at: https://drive.google.com/?usp=chrome_app#folders/0B_F4eBeBQc3ybElEeEhqME5DQkU) and a video tutorial (https://www.youtube.com/watch?v=yVPTgxg-SIk).

Drift-Implicit Multi-Level Monte Carlo Tau-Leap Methods for Stochastic Reaction Networks

KAUST Repository

Ben Hammouda, Chiheb

2015-05-12

In biochemical systems, stochastic e↵ects can be caused by the presence of small numbers of certain reactant molecules. In this setting, discrete state-space and stochastic simulation approaches were proved to be more relevant than continuous state-space and deterministic ones. These stochastic models constitute the theory of stochastic reaction networks (SRNs). Furthermore, in some cases, the dynamics of fast and slow time scales can be well separated and this is characterized by what is called sti↵ness. For such problems, the existing discrete space-state stochastic path simulation methods, such as the stochastic simulation algorithm (SSA) and the explicit tau-leap method, can be very slow. Therefore, implicit tau-leap approxima- tions were developed to improve the numerical stability and provide more e cient simulation algorithms for these systems. One of the interesting tasks for SRNs is to approximate the expected values of some observables of the process at a certain fixed time T. This is can be achieved using Monte Carlo (MC) techniques. However, in a recent work, Anderson and Higham in 2013, proposed a more computationally e cient method which combines multi-level Monte Carlo (MLMC) technique with explicit tau-leap schemes. In this MSc thesis, we propose new fast stochastic algorithm, particularly designed 5 to address sti↵ systems, for approximating the expected values of some observables of SRNs. In fact, we take advantage of the idea of MLMC techniques and drift-implicit tau-leap approximation to construct a drift-implicit MLMC tau-leap estimator. In addition to accurately estimating the expected values of a given observable of SRNs at a final time T , our proposed estimator ensures the numerical stability with a lower cost than the MLMC explicit tau-leap algorithm, for systems including simultane- ously fast and slow species. The key contribution of our work is the coupling of two drift-implicit tau-leap paths, which is the basic brick for

We assessed safe injection practices among 1100 health-care workers in 25 health-care facilities in Gharbiya Governorate. Questionnaires were used to collect information and 278 injections were observed using a standardized checklist. There was a lack of infection control policies in all the facilities and a lack of many supplies needed for safe injection. Proper needle manipulation before disposal was observed in only 41% of injections, safe needle disposal in 47.5% and safe syringe disposal in 0%. Reuse of used syringes and needles was reported by 13.2% of the health-care workers and 66.2% had experienced a needle-stick injury. Only 11.3% had received a full course of hepatitis B vaccination.

Outdoor workers are especially susceptible to skin cancer--the most common, but also one of the most preventable, forms of cancer. Colorado, the location of the study, has the second highest rate of skin cancer deaths in the nation. Local government managers in Colorado-in municipalities, counties, and special districts-were surveyed to ascertain the extent to which they engage in formal (written) and informal practices to protect their outdoor workers against excessive exposure to sun. The survey consisted of 51 questions assessing awareness of formal or informal practices for sun protection of outdoor workers. An index of practices--the study's dependent variable--was created that was composed or practices such as providing employees free or reduced-cost sunscreen, wide-brimmed hats, sunglasses, long-sleeved work shirts, long work pants, and temporary or permanent outdoor shade shelters. Proscriptive policies, such as restricting the use of broad brimmed hats, were subtracted from the index. Surveys were completed by 825 administrators representing 98 jurisdictions. Responses from administrators in the same jurisdiction were averaged. More than 40% of responding jurisdictions indicated that they engaged in informal sun safety practices. Tests conducted to determine what variables might account for the adoption of these sun protection practices found that the degree to which a community could be regarded as cosmopolite and as having an individualistic political culture were significant predictors. Type of government was also significant. Although, higher community income was a significant predictor, neither local government budget nor size was significant. The adoption of sun safe practices bears low costs with potentially high returns. Findings from this study suggest that awareness campaigns might most effectively target cosmopolite communities, but that the greatest impact might be achieved by targeting localite communities. Government size and budget do not

The Leap Motion Controller is a new device for hand gesture controlled user interfaces with declared sub-millimeter accuracy. However, up to this point its capabilities in real environments have not been analyzed. Therefore, this paper presents a first study of a Leap Motion Controller. The main focus of attention is on the evaluation of the accuracy and repeatability. For an appropriate evaluation, a novel experimental setup was developed making use of an industrial robot with a reference pen allowing a position accuracy of 0.2 mm. Thereby, a deviation between a desired 3D position and the average measured positions below 0.2 mm has been obtained for static setups and of 1.2 mm for dynamic setups. Using the conclusion of this analysis can improve the development of applications for the Leap Motion controller in the field of Human-Computer Interaction.

An improved shuffled frog leaping algorithm based evolutionary framework for currency exchange rate prediction

Dash, Rajashree

2017-11-01

Forecasting purchasing power of one currency with respect to another currency is always an interesting topic in the field of financial time series prediction. Despite the existence of several traditional and computational models for currency exchange rate forecasting, there is always a need for developing simpler and more efficient model, which will produce better prediction capability. In this paper, an evolutionary framework is proposed by using an improved shuffled frog leaping (ISFL) algorithm with a computationally efficient functional link artificial neural network (CEFLANN) for prediction of currency exchange rate. The model is validated by observing the monthly prediction measures obtained for three currency exchange data sets such as USD/CAD, USD/CHF, and USD/JPY accumulated within same period of time. The model performance is also compared with two other evolutionary learning techniques such as Shuffled frog leaping algorithm and Particle Swarm optimization algorithm. Practical analysis of results suggest that, the proposed model developed using the ISFL algorithm with CEFLANN network is a promising predictor model for currency exchange rate prediction compared to other models included in the study.

Nurses' clinical reasoning practices that support safe medication administration: An integrative review of the literature.

Science.gov (United States)

Rohde, Emily; Domm, Elizabeth

2018-02-01

To review the current literature about nurses' clinical reasoning practices that support safe medication administration. The literature about medication administration frequently focuses on avoiding medication errors. Nurses' clinical reasoning used during medication administration to maintain medication safety receives less attention in the literature. As healthcare professionals, nurses work closely with patients, assessing and intervening to promote mediation safety prior to, during and after medication administration. They also provide discharge teaching about using medication safely. Nurses' clinical reasoning and practices that support medication safety are often invisible when the focus is medication errors avoidance. An integrative literature review was guided by Whittemore and Knafl's (Journal of Advanced Nursing, 5, 2005 and 546) five-stage review of the 11 articles that met review criteria. This review is modelled after Gaffney et al.'s (Journal of Clinical Nursing, 25, 2016 and 906) integrative review on medical error recovery. Health databases were accessed and systematically searched for research reporting nurses' clinical reasoning practices that supported safe medication administration. The level and quality of evidence of the included research articles were assessed using The Johns Hopkins Nursing Evidence-Based Practice Rating Scale©. Nurses have a central role in safe medication administration, including but not limited to risk awareness about the potential for medication errors. Nurses assess patients and their medication and use knowledge and clinical reasoning to administer medication safely. Results indicated nurses' use of clinical reasoning to maintain safe medication administration was inadequately articulated in 10 of 11 studies reviewed. Nurses are primarily responsible for safe medication administration. Nurses draw from their foundational knowledge of patient conditions and organisational processes and use clinical reasoning that

Full Text Available The Leap Motion Controller is a new device for hand gesture controlled user interfaces with declared sub-millimeter accuracy. However, up to this point its capabilities in real environments have not been analyzed. Therefore, this paper presents a first study of a Leap Motion Controller. The main focus of attention is on the evaluation of the accuracy and repeatability. For an appropriate evaluation, a novel experimental setup was developed making use of an industrial robot with a reference pen allowing a position accuracy of 0.2 mm. Thereby, a deviation between a desired 3D position and the average measured positions below 0.2mmhas been obtained for static setups and of 1.2mmfor dynamic setups. Using the conclusion of this analysis can improve the development of applications for the Leap Motion controller in the field of Human-Computer Interaction.

LEAP: A balloon-borne search for low-energy cosmic ray antiprotons

Science.gov (United States)

Moats, Anne Rosalie Myers

The LEAP (Low Energy Antiproton) experiment is a search for cosmic ray antiprotons in the 120 MeV to 1.2 GeV kinetic energy range. The motivation for this project was the result announced by Buffington et al. (1981) that indicated an anomalously high antiproton flux below 300 MeV; this result has compelled theorists to propose sources of primary antiprotons above the small secondary antiproton flux produced by high energy cosmic ray collisions with nuclei in the interstellar medium. LEAP consisted of the NMSU magnet spectrometer, a time-of-flight system designed at NASA-Goddard, two scintillation detectors, and a Cherenkov counter. Analysis of flight data performed by the high energy astrophysics group at Goddard Space Flight Center revealed no antiproton candidates found in the 120 MeV to 360 MeV range; 3 possible antiproton candidate events were found in the 500 MeV to 1.2 GeV range in an analysis done here at the University of Arizona. However, since it will be necessary to sharpen the calibration on all of the LEAP systems in order to positively identify these events as antiprotons, only an upper limit has been determined at present. Thus, combining the analyses performed at the University of Arizona and NASA-Goddard, 90 percent confidence upper limits of 3.5 x 10-5 in the 120 MeV to 360 MeV range and 2.3 x 10-4 in the 500 MeV to 1.2 GeV range for the antiproton/proton ratio is indicated by the LEAP results. LEAP disagrees sharply with the results of the Buffington group, indicating a low antiproton flux at these energies. Thus, a purely secondary antiproton flux may be adequate at low energies.

Initial Experiments with the Leap Motion as a User Interface in Robotic Endonasal Surgery.

Travaglini, T A; Swaney, P J; Weaver, Kyle D; Webster, R J

The Leap Motion controller is a low-cost, optically-based hand tracking system that has recently been introduced on the consumer market. Prior studies have investigated its precision and accuracy, toward evaluating its usefulness as a surgical robot master interface. Yet due to the diversity of potential slave robots and surgical procedures, as well as the dynamic nature of surgery, it is challenging to make general conclusions from published accuracy and precision data. Thus, our goal in this paper is to explore the use of the Leap in the specific scenario of endonasal pituitary surgery. We use it to control a concentric tube continuum robot in a phantom study, and compare user performance using the Leap to previously published results using the Phantom Omni. We find that the users were able to achieve nearly identical average resection percentage and overall surgical duration with the Leap.

Science.gov (United States)

Fowler, Aja J; Evans, Patricia W; Etchegaray, Jason M; Ottenbacher, Allison; Arnold, Cody

2013-11-01

Our primary objective was to compare parents of infants cared for in newborn intensive care units (NICUs) and infants cared for in well-baby ("general") nurseries with regard to knowledge and practice of safe sleep practices/sudden infant death syndrome risk reduction measures and guidelines. Our secondary objective was to obtain qualitative data regarding reasons for noncompliance in both populations. Sixty participants (30 from each population) completed our survey measuring safe sleep knowledge and practice. Parents of NICU infants reported using 2 safe sleep practices-(a) always placing baby in crib to sleep and (b) always placing baby on back to sleep-significantly more frequently than parents of well infants. Additional findings and implications for future studies are discussed.

This paper presents a Fitts' law-based analysis of the user's performance in selection tasks with the Leap Motion Controller compared with a standard mouse device. The Leap Motion Controller (LMC) is a new contact-free input system for gesture-based human-computer interaction with declared sub-millimeter accuracy. Up to this point, there has hardly been any systematic evaluation of this new system available. With an error rate of 7.8% for the LMC and 2.8% for the mouse device, movement times twice as large as for a mouse device and high overall effort ratings, the Leap Motion Controller's performance as an input device for everyday generic computer pointing tasks is rather limited, at least with regard to the selection recognition provided by the LMC.

The development of navigation technology facilitating MRI-guided stereotactic neurosurgery has enabled neurosurgeons to perform a variety of procedures ranging from deep brain stimulation to laser ablation entirely within an intraoperative or diagnostic MRI suite while having real-time visualization of brain anatomy. Prior to this technology, some of these procedures required multisite workflow patterns that presented significant risk to the patient during transport. For those facilities with access to this technology, safe practice guidelines exist only for procedures performed within an intraoperative MRI. There are currently no safe practice guidelines or parameters available for facilities looking to integrate this technology into practice in conventional MRI suites. Performing neurosurgical procedures in a diagnostic MRI suite does require precautionary measures. The relative novelty of technology and workflows for direct MRI-guided procedures requires consideration of safe practice recommendations, including those pertaining to infection control and magnet safety issues. This article proposes a framework of safe practice recommendations designed for assessing readiness and optimization of MRI-guided neurosurgical interventions in the diagnostic MRI suite in an effort to mitigate patient risk. The framework is based on existing clinical evidence, recommendations, and guidelines related to infection control and prevention, health care-associated infections, and magnet safety, as well as the clinical and practical experience of neurosurgeons utilizing this technology. © 2017 American Society for Healthcare Risk Management of the American Hospital Association.

2013-08-01

Full Text Available Introduction: For maintaining the continuity of care and improving the quality of care, effective inter-shift information communication is necessary. Any handover error can endanger patient safety. Despite the importance of shift handover, there is no standard handover protocol in our healthcare settings. Methods In this one-group pretest-posttest quasi-experimental study conducted in spring and summer of 2011, we recruited a convenience sample of 56 ICU nurses. The Nurses’ Safe Practice Evaluation Checklist was used for data collection. The Content Validity Index and the inter-rater correlation coefficient of the checklist was 0.92 and 89, respectively. We employed the SPSS 11.5 software and the Mc Nemar and paired-samples t test for data analysis. Results: Study findings revealed that nurses’ mean score on the Safe Practice Evaluation Checklist increased significantly from 11.6 (2.7 to 17.0 (1.8 (P < 0.001. Conclusion: using a standard handover protocol for communicating patient’s needs and information improves nurses’ safe practice in the area of basic nursing care.

Multilevel hybrid split-step implicit tau-leap

KAUST Repository

Ben Hammouda, Chiheb

2016-06-17

In biochemically reactive systems with small copy numbers of one or more reactant molecules, the dynamics is dominated by stochastic effects. To approximate those systems, discrete state-space and stochastic simulation approaches have been shown to be more relevant than continuous state-space and deterministic ones. In systems characterized by having simultaneously fast and slow timescales, existing discrete space-state stochastic path simulation methods, such as the stochastic simulation algorithm (SSA) and the explicit tau-leap (explicit-TL) method, can be very slow. Implicit approximations have been developed to improve numerical stability and provide efficient simulation algorithms for those systems. Here, we propose an efficient Multilevel Monte Carlo (MLMC) method in the spirit of the work by Anderson and Higham (SIAM Multiscal Model. Simul. 10(1), 2012). This method uses split-step implicit tau-leap (SSI-TL) at levels where the explicit-TL method is not applicable due to numerical stability issues. We present numerical examples that illustrate the performance of the proposed method. © 2016 Springer Science+Business Media New York

Full Text Available The content of this article is structured in three sections: 1- Preamble, 2- Contradictions and dialectical overcoming the history of education, 3- Social Movements and Historical-Critical Pedagogy in Brazil. Identifies relationships between experiences of qualitative change of the social order in the sixteenth, eighteenth and nineteenth centuries, and education as political and pedagogical element constitutive of revolutionary processes. It is evident that among the conservative ideologies of the old social order, played by the Church and bourgeois state, emerge new perspectives of education and society, thus overcoming the contradictions produce processes that can be identified in the history of education. Social movements as an expression of conflicts between these ideologies can be strengthened to the extent that work with the prospect of united struggles and deepen their strategies from their anchorage in the historical-dialectical materialism. The Historical- Critical Pedagogy, as a theoretical and practical perspective grounded in Marxist thought, has been linked to social movements and pedagogical processes in and out of school, contributing to a qualitative leap occurs in national education and the struggles of building the socialism.

Code of practice for the safe use of industrial radiography equipment (1989)

International Nuclear Information System (INIS)

1989-12-01

This code supersedes the Code of practice for the control and safe handling of sealed radioactive sources used in industrial radiography, published by the National Health and Medical Research Council (NHMRC) in 1968. It differs significantly from the former code because radiation protection practice and recommended standards have changed. The code covers the design, construction and requirements for the safe use of X-radiography equipment and gamma-radiography equipment. It provides illustrative working rules, detailed emergency procedures and comprehensive responsibilities and duties for all personnel involved in supplying and using industrial radiography equipment. The code details those equipment requirements, personnel requirements and work practices that the NHMRC considers necessary to keep exposures to ionizing radiation as low as reasonably achievable. Some equipment and facilities currently in use may not meet all of the mandatory requirements of this code. These requirements have been included in the code to encourage progress towards future compliance in the expectation that, in the interim, statutory authorities will apply them with discretion

Context Outdoor workers are especially susceptible to skin cancer, the most common, but also one of the most preventable, forms of cancer. Colorado, the location of the study, has the second highest rate of skin cancer deaths in the nation. Objective Local government managers in Colorado—in municipalities, counties and special districts—were surveyed in order to ascertain the extent to which they engage in formal (written) and informal practices to protect their outdoor workers against excessive exposure to sun. Design The survey consisted of 51 question assessing awareness of formal or informal practices for sun protection of outdoor workers. An index of practices--the study's dependent variable--was created that was comprised or practices such as providing employees free or reduced-cost sunscreen, wide-brimmed hats, sunglasses, long-sleeved work shirts, long work pants, and temporary or permanent outdoor shade shelters. Proscriptive policies, such as restricting the use of broad brimmed hats, were subtracted from the index. Surveys were completed by 825 administrators representing 98 jurisdictions. Responses from administrators in the same jurisdiction were averaged. Results Over 40 percent of responding jurisdictions indicated that they engaged in informal sun safety practices. Tests conducted to determine what variables might account for the adoption of these sun protection practices found that the degree to which a community could be regarded as cosmopolite and as having an individualistic political culture were significant predictors. Type of government was also significant. Although, higher community income was a significant predictor, neither local government budget nor size was significant. Conclusions The adoption of sun safe practices bears low costs with potentially high returns. Findings from this study suggest that awareness campaigns might most effectively target cosmopolite communities, but that the greatest impact might be achieved by targeting

We present a simple model for neural signaling leaps in the brain considering only the thermodynamic (Nernst) potential in neuron cells and brain temperature. We numerically simulated connections between arbitrarily localized neurons and analyzed the frequency distribution of the distances reached. We observed qualitative change between Normal statistics (with T 37.5 0 C, awaken regime) and Levy statistics (T = 35.5 0 C, sleeping period), characterized by rare events of long range connections.

The Leaping on with Language programme provides a combination of strategies and activities to accelerate children's spoken language use from simple sentences to complex language. Using a conversational philosophy it expands the building blocks of language (vocabulary, grammar, speech), whilst emphasising the importance of developing independent social communication and acknowledging a child's developing self esteem and self identity between the ages of 4-11. Three pilot projects evaluated the programme with a total of 51 delegates. The outcomes were hugely positive. Changes in behaviour were reported from the 3rd pilot 1 month later. Comments regarding the length of training, practical strategies and more film clips were implemented. Leaping on with language is now a free to access resource available on line.

Safe Operation of Nuclear Power Plants. Code of Practice and Technical Appendices

International Nuclear Information System (INIS)

1969-01-01

This book is in two parts. The first is a Code of Practice for the Safe Operation of Nuclear Power Plants and the second part is a compilation of technical appendices. Its object is to give information and illustrative examples that would be helpful in implementing the Code of Practice. This second part, although published under the same cover, is not part of the Code. Safe operation of a nuclear power plant postulates suitable siting and proper design, construction and management of the plant. Under the present Code of Practice for the Safe Operation of Nuclear Power Plants, those intending to operate the plant are recommended to prepare documentation which would deal with its operation and include safety analyses. The documentation in question would be reviewed by a regulatory body independent of the operating organization; operation would be authorized on the understanding that it would comply with limits and conditions designed to ensure safety. The Code may be subject to revision in the light of experience. The Appendices provide additional information together with some examples relating to certain topics dealt with in the Code; it must be emphasized that they are included as examples for information only and are not part of any recommendation. Purpose and scope: The recommendations in the Code are designed to protect the general public and the operating personnel from radiation hazards, and the Code forms part of the Agency's Safety Standards. The Code, which should be used in conjunction with the Agency's other Safety Standards, provides guidance and information to persons and authorities responsible for the operation of stationary nuclear power plants whose main function is the generation of thermal, mechanical or electrical power; it is not intended to apply to reactors used solely for experimental or research purposes. It sets forth minimum requirements which, it is believed, in the light of experience, must be met in order to achieve safe operation of a

Berg, Siv Hilde; Rørtveit, Kristine; Walby, Fredrik A; Aase, Karina

2017-01-27

Suicide prevention in psychiatric care is arguably complex and incompletely understood as a patient safety issue. A resilient healthcare approach provides perspectives through which to understand this complexity by understanding everyday clinical practice. By including suicidal patients and healthcare professionals as sources of knowledge, a deeper understanding of what constitutes safe clinical practice can be achieved. This planned study aims to adopt the perspective of resilient healthcare to provide a deeper understanding of safe clinical practice for suicidal patients in psychiatric inpatient care. It will describe the experienced components and conditions of safe clinical practice and the experienced practice of patient safety. The study will apply a descriptive case study approach consisting of qualitative semistructured interviews and focus groups. The data sources are hospitalised patients in a suicidal crisis and healthcare professionals in clinical practice. This study was approved by the Regional Ethics Committee (2016/34). The results will be disseminated through scientific articles, a PhD dissertation, and national and international conferences. These findings can generate knowledge to be integrated into the practice of safety for suicidal inpatients in Norway and to improve the feasibility of patient safety measures. Theoretical generalisations can be drawn regarding safe clinical practice by taking into account the experiences of patients and healthcare professionals. Thus, this study can inform the conceptual development of safe clinical practice for suicidal patients. Published by the BMJ Publishing Group Limited.

Expression of chicken LEAP-2 in the reproductive organs and embryos and in response to Salmonella enterica infection.

Science.gov (United States)

Michailidis, Georgios

2010-06-01

In recent years host antimicrobial peptides and proteins have been recognised as key mediators of the innate immune response in many vertebrate species, providing the first line of defense against potential pathogens. In chickens a number of cationic antimicrobial peptides have been recently identified. However, although these peptides have been studied extensively in the avian gastrointestinal tract, little is known about their function in the chicken reproductive organs and embryos. Chicken Liver Expressed Antimicrobial Peptide-2 (cLEAP-2) has been previously reported to function in protecting birds against microbial attack. The aim of this study was to investigate the expression of cLEAP-2 gene in the chicken reproductive organs, as well as in chicken embryos during embryonic development, and to determine whether cLEAP-2 expression in the chicken reproductive organs was constitutive or induced as a response to Salmonella enteritidis infection. RNA was extracted from ovary, oviduct, testis and epididymis of sexually mature healthy and Salmonella infected birds, as well as from chicken embryos until day ten of embryonic development. Expression analysis data revealed that cLEAP-2 was expressed in the chicken ovary, testis and epididymis as well as in embryos during early embryonic development. Quantitative real-time PCR analysis revealed that cLEAP-2 expression was constitutive in the chicken epididymis, but was significantly up regulated in the chicken gonads, following Salmonella infection. In addition, expression of cLEAP-2 during chicken embryogenesis appeared to be developmentally regulated. These data provide evidence to suggest a key role of cLEAP-2 in the protection of the chicken reproductive organs and the developing embryos from Salmonella colonization.

Leap Motion Device Used to Control a Real Anthropomorphic Gripper

Directory of Open Access Journals (Sweden)

Ionel Staretu

2016-06-01

Full Text Available This paper presents for the first time the use of the Leap Motion device to control an anthropomorphic gripper with five fingers. First, a description of the Leap Motion device is presented, highlighting its main functional characteristics, followed by testing of its use for capturing the movements of a human hand's fingers in different configurations. Next, the HandCommander soft module and the Interface Controller application are described. The HandCommander is a software module created to facilitate interaction between a human hand and the GraspIT virtual environment, and the Interface Controller application is required to send motion data to the virtual environment and to test the communication protocol. For the test, a prototype of an anthropomorphic gripper with five fingers was made, including a proper hardware system of command and control, which is briefly presented in this paper. Following the creation of the prototype, the command system performance test was conducted under real conditions, evaluating the recognition efficiency of the objects to be gripped and the efficiency of the command and control strategies for the gripping process. The gripping test is exemplified by the gripping of an object, such as a screw spanner. It was found that the command system, both in terms of capturing human hand gestures with the Leap Motion device and effective object gripping, is operational. Suggestive figures are presented as examples.

SparseLeap: Efficient Empty Space Skipping for Large-Scale Volume Rendering

KAUST Repository

Hadwiger, Markus; Al-Awami, Ali K.; Beyer, Johanna; Agus, Marco; Pfister, Hanspeter

2017-01-01

Recent advances in data acquisition produce volume data of very high resolution and large size, such as terabyte-sized microscopy volumes. These data often contain many fine and intricate structures, which pose huge challenges for volume rendering, and make it particularly important to efficiently skip empty space. This paper addresses two major challenges: (1) The complexity of large volumes containing fine structures often leads to highly fragmented space subdivisions that make empty regions hard to skip efficiently. (2) The classification of space into empty and non-empty regions changes frequently, because the user or the evaluation of an interactive query activate a different set of objects, which makes it unfeasible to pre-compute a well-adapted space subdivision. We describe the novel SparseLeap method for efficient empty space skipping in very large volumes, even around fine structures. The main performance characteristic of SparseLeap is that it moves the major cost of empty space skipping out of the ray-casting stage. We achieve this via a hybrid strategy that balances the computational load between determining empty ray segments in a rasterization (object-order) stage, and sampling non-empty volume data in the ray-casting (image-order) stage. Before ray-casting, we exploit the fast hardware rasterization of GPUs to create a ray segment list for each pixel, which identifies non-empty regions along the ray. The ray-casting stage then leaps over empty space without hierarchy traversal. Ray segment lists are created by rasterizing a set of fine-grained, view-independent bounding boxes. Frame coherence is exploited by re-using the same bounding boxes unless the set of active objects changes. We show that SparseLeap scales better to large, sparse data than standard octree empty space skipping.

A bench-scale photobioreactor system, termed Laboratory Environmental Algae Pond Simulator (LEAPS), was designed and constructed to simulate outdoor pond cultivation for a wide range of geographical locations and seasons. The LEAPS consists of six well-mixed glass column photobioreactors sparged with CO2-enriched air to maintain a set-point pH, illuminated from above by a programmable multicolor LED lighting (0 to 2,500 µmol/m2-sec), and submerged in a temperature controlled water-bath (-2 °C to >60 °C). Measured incident light intensities and water temperatures deviated from the respective light and temperature set-points on average only 2.3% and 0.9%, demonstrating accurate simulation of light and temperature conditions measured in outdoor ponds. In order to determine whether microalgae strains cultured in the LEAPS exhibit the same linear phase biomass productivity as in outdoor ponds, Chlorella sorokiniana and Nannochloropsis salina were cultured in the LEAPS bioreactors using light and temperature scripts measured previously in the respective outdoor pond studies. For Chlorella sorokiniana, the summer season biomass productivity in the LEAPS was 6.6% and 11.3% lower than in the respective outdoor ponds in Rimrock, Arizona, and Delhi, California; however, these differences were not statistically significant. For Nannochloropsis salina, the winter season biomass productivity in the LEAPS was statistically significantly higher (15.2%) during the 27 day experimental period than in the respective outdoor ponds in Tucson, Arizona. However, when considering only the first 14 days, the LEAPS biomass productivity was only 9.2% higher than in the outdoor ponds, a difference shown to be not statistically significant. Potential reasons for the positive or negative divergence in LEAPS performance, relative to outdoor ponds, are discussed. To demonstrate the utility of the LEAPS in predicting productivity, two other strains – Scenedesmus obliquus and Stichococcus minor

Fuenkajorn, K.; Daemen, J.J.K.

1991-06-01

An empirical criterion is formulated to describe the compressive strength of the densely welded Apache Leap tuff. The criterion incorporates the effects of size, L/D ratio, loading rate and density variations. The criterion improves the correlation between the test results and the failure envelope. Uniaxial and triaxial compressive strengths, Brazilian tensile strength and elastic properties of the densely welded brown unit of the Apache Leap tuff have been determined using the ASTM standard test methods. All tuff samples are tested dry at room temperature (22 ± 2 degrees C), and have the core axis normal to the flow layers. The uniaxial compressive strength is 73.2 ± 16.5 MPa. The Brazilian tensile strength is 5.12 ± 1.2 MPa. The Young's modulus and Poisson's ratio are 22.6 ± 5.7 GPa and 0.20 ± 0.03. Smoothness and perpendicularity do not fully meet the ASTM requirements for all samples, due to the presence of voids and inclusions on the sample surfaces and the sample preparation methods. The investigations of loading rate, L/D radio and cyclic loading effects on the compressive strength and of the size effect on the tensile strength are not conclusive. The Coulomb strength criterion adequately represents the failure envelope of the tuff under confining pressures from 0 to 62 MPa. Cohesion and internal friction angle are 16 MPa and 43 degrees. The brown unit of the Apache Leap tuff is highly heterogeneous as suggested by large variations of the test results. The high intrinsic variability of the tuff is probably caused by the presence of flow layers and by nonuniform distributions of inclusions, voids and degree of welding. Similar variability of the properties has been found in publications on the Topopah Spring tuff at Yucca Mountain. 57 refs., 32 figs., 29 tabs

The use of collaboration to implement evidence-based safe practices.

Science.gov (United States)

Clarke, John R

2013-12-01

The Pennsylvania Patient Safety Authority receives over 235,000 reports of medical error per year. Near miss and serious event reports of common and interesting problems are analysed to identify best practices for preventing harmful errors. Dissemination of this evidence-based information in the peer-reviewed Pennsylvania Patient Safety Advisory and presentations to medical staffs are not sufficient for adoption of best practices. Adoption of best practices has required working with institutions to identify local barriers to and incentives for adopting best practices and redesigning the delivery system to make desired behaviour easy and undesirable behaviour more difficult. Collaborations, where institutions can learn from the experiences of others, have show decreases in harmful events. The Pennsylvania Program to Prevent Wrong-Site Surgery is used as an example. Two collaborations to prevent wrong-site surgery have been completed, one with 30 institutions in eastern Pennsylvania and one with 19 in western Pennsylvania. The first collaboration achieved a 73% decrease in the rolling average of wrong-site events over 18 months. The second collaboration experienced no wrong-site operating room procedures over more than one year. Significance for public healthSince the Institute of Medicine's To Err is Human identified medical errors as a major cause of death, the public has been interested in the recommendations for reporting of medical errors and implementing safe systems for the delivery of healthcare. The Commonwealth of Pennsylvania has followed those recommendations and found that an essential intermediate step between analysing reports and implementing safe systems is collaborative learning among healthcare institutions. The experience in Pennsylvania should be useful to other public organizations wishing to improve safety.

LEAP [Low-Energy Antiproton]: A balloon-borne search for low-energy cosmic-ray antiprotons

International Nuclear Information System (INIS)

Moats, A.R.M.

1989-01-01

The LEAP (Low-Energy Antiproton) experiment is a search for cosmic-ray antiprotons in the 120 MeV to 1.2 GeV kinetic energy range. The motivation for this project was the result announced by Buffington et. al. (1981) that indicated an anomalously high antiproton flux below 300 MeV; this result has compelled theorists to propose sources of primary antiprotons above the small secondary antiproton flux produced by high energy cosmic-ray collisions with nuclei in the interstellar medium. LEAP consisted of the NMSU magnetic spectrometer, a time-of-flight system designed at Goddard Space Flight Center, two scintillation detectors, and a Cherenkov counter designed and built at the University of Arizona. Analysis of flight data performed by the high-energy astrophysics group at Goddard Space Flight Center revealed no antiproton candidates found in the 120 MeV to 360 MeV range; 3 possible antiproton candidate events were found in the 500 MeV to 1.2 GeV range in an analysis done here at the University of Arizona. However, since it will be necessary to sharpen the calibration on all of the LEAP systems in order to positively identify these events as antiprotons, only an upper limit has been determined at present. Thus, combining the analyses performed at the University of Arizona and Goddard Space Flight Center, 90% confidence upper limits of 3.5 x 10 -5 in the 120 MeV to 360 MeV range and 2.3 x 10 -4 in the 500 MeV to 1.2 GeV range for the antiproton/proton ratio is indicated by the LEAP results. LEAP disagrees sharply with the results of the Buffington group, indicating a low antiproton flux at these energies

To identify gender difference in safe and unsafe practice of pesticide handling in tobacco farmers of Malaysia, we conducted a 20-item questionnaire interview on storage of pesticide (4 questions), mixing of pesticide (3 questions), use of personal protective equipment and clothing while spraying pesticide (7 questions), activities during and after spraying of pesticide (5 questions), and maintenance of pesticide sprayer (1 question) in 496 tobacco farmers (395 males and 101 females) in Bachok District, Kelantan, Malaysia. Duration of employment was significantly longer in females than those in males (pwork habit, (3) reading and following instructions on pesticide label, (4) security, storage and disposal of pesticide container, (5) safe work habit, (6) proper handling of pesticide and maintenance of pesticide sprayer, (7) use of personal protective clothing, and (8) safe handling of pesticide. Results of analysis of covariance for the eight factor scores of all male and female farmers, controlling for educational level and duration of employment, showed that: (1) factor scores for use of personal protective equipment (pwork habit (p0.05). We therefore conclude that: (1) for female tobacco farmers, choice of personal attire tend to result in lower scores on use of personal protective equipment and personal protective clothing while personal hygiene practices result in lower score on safe work habit; and, (2) for male tobacco farmers, the lower scores on reading and following instruction on pesticide label and mixing pesticide and maintenance of pesticide sprayer in good condition suggests that they were not primarily involved in these activities. It is postulated that these differences in safe and unsafe practices of pesticide handling across gender is related to the choice of personal attire, personal hygiene practices and division of labour within farming households which in turn is influenced by prevailing sociocultural norms in the community.

The Lifestyle Engagement Activity Program (LEAP) incorporates social support and recreational activities into case-managed home care. This study's aim was to evaluate the effect of LEAP on engagement, mood, and behavior of home care clients, and on case managers and care workers. Quasi-experimental. Five Australian aged home care providers, including 2 specializing in care for ethnic minorities. Clients (n = 189) from 5 home care providers participated. The 12-month program had 3 components: (1) engaging support of management and staff; (2) a champion to drive practice change; (3) staff training. Case managers were trained to set meaningful social and/or recreational goals during care planning. Care workers were trained in good communication, to promote client independence and choice, and in techniques such as Montessori activities, reminiscence, music, physical activity, and humor. Data were collected 6 months before program commencement, at baseline, and 6 and 12 months. The Homecare Measure of Engagement Staff report and Client-Family interview were primary outcomes. Secondary outcomes were the Cohen-Mansfield Agitation Inventory; apathy, dysphoria, and agitation subscales of the Neuropsychiatric Inventory-Clinician Rating; the geriatric depression scale; UCLA loneliness scale; and home care satisfaction scale. Staff provided information on confidence in engaging clients and the Utrecht Work Engagement Scale. Twelve months after program commencement, clients showed a significant increase in self- or family-reported client engagement (b = 5.39, t[113.09] = 3.93, P recreationally engage clients (b = 0.52, t(21.33) = 2.80, P = .011, b = 0.29, t(198.69) = 2.58, P = .011, respectively). There were no significant changes in care worker-rated client engagement or client or family self-complete measures of depression or loneliness (P > .05). Client and family self-rated apathy increased over 12 months (b = 0.04, t(43.36) = 3.06, P = .004; b = 3.63, t(34.70) = 2.20, P

Interaction between HIV awareness, knowledge, safe sex practice and HIV prevalence: evidence from Botswana.

Science.gov (United States)

Ray, Ranjan; Sinha, Kompal

2012-05-01

This paper makes methodological and empirical contributions to the study of HIV in the context of Botswana, a country with high HIV prevalence. Comparable evidence is presented from India to put the Botswana results in perspective. The results point to the strong role played by affluence and education in increasing HIV knowledge, promoting safe sex and reducing HIV prevalence. The study presents African evidence on the role played by the empowerment of women in promoting safe sex practices such as condom use. The lack of significant association between HIV prevalence and safe sex practice points to the danger of HIV-infected individuals spreading the disease through multiple sex partners and unprotected sex. This danger is underlined by the finding that females with multiple sex partners are at higher risk of being infected with HIV. These results take on special policy significance in the context of Botswana, where the issue of multiple sex partners has not been adequately addressed in the programme to contain the spread of HIV.

2018-01-01

We announce barycorrpy (BCPy) , a Python implementation to calculate precise barycentric corrections well below the 1 cm/s level, following the algorithm of Wright and Eastman (2014). This level of precision is required in the search for 1 Earth mass planets in the Habitable Zones of Sun-like stars by the Radial Velocity (RV) method, where the maximum semi-amplitude is about 9 cm/s. We have developed BCPy to be used in the pipeline for the next generation Doppler Spectrometers - Habitable-zone Planet Finder (HPF) and NEID. In this work, we also develop an automated leap second management routine to improve upon the one available in Astropy. It checks for and downloads a new leap second file before converting from the UT time scale to TDB.

Although motion analysis is frequently employed in upper limb motor assessment (e.g. visually-guided reaching), they are resource-intensive and limited to laboratory settings. This study evaluated the reliability and accuracy of a new markerless motion capture device, the Leap Motion controller, to measure finger position. Testing conditions that influence reliability and agreement between the Leap and a research-grade motion capture system were examined. Nine healthy young adults pointed to 15 targets on a computer screen under two conditions: (1) touching the target (touch) and (2) 4 cm away from the target (no-touch). Leap data was compared to an Optotrak marker attached to the index finger. Across all trials, root mean square (RMS) error of the Leap system was 17.30  ±  9.56 mm (mean ± SD), sampled at 65.47  ±  21.53 Hz. The % viable trials and mean sampling rate were significantly lower in the touch condition (44% versus 64%, p motion capture systems, the Leap Motion controller is sufficiently reliable for measuring motor performance in pointing tasks that do not require high positional accuracy (e.g. reaction time, Fitt's, trails, bimanual coordination).

2016-07-01

Full Text Available Optimization of hole-making operations in manufacturing industry plays a vital role. Tool travel and tool switch planning are the two major issues in hole-making operations. Many industrial applications such as moulds, dies, engine block, automotive parts etc. requires machining of large number of holes. Large number of machining operations like drilling, enlargement or tapping/reaming are required to achieve the final size of individual hole, which gives rise to number of possible sequences to complete hole-making operations on the part depending upon the location of hole and tool sequence to be followed. It is necessary to find the optimal sequence of operations which minimizes the total processing cost of hole-making operations. In this work, therefore an attempt is made to reduce the total processing cost of hole-making operations by applying relatively new optimization algorithms known as shuffled frog leaping algorithm and proposed modified shuffled frog leaping algorithm for the determination of optimal sequence of hole-making operations. An industrial application example of ejector plate of injection mould is considered in this work to demonstrate the proposed approach. The obtained results by the shuffled frog leaping algorithm and proposed modified shuffled frog leaping algorithm are compared with each other. It is seen from the obtained results that the results of proposed modified shuffled frog leaping algorithm are superior to those obtained using shuffled frog leaping algorithm.

To present athletic trainers with recommendations for safe weight loss and weight maintenance practices for athletes and active clients and to provide athletes, clients, coaches, and parents with safe guidelines that will allow athletes and clients to achieve and maintain weight and body composition goals. Unsafe weight management practices can compromise athletic performance and negatively affect health. Athletes and clients often attempt to lose weight by not eating, limiting caloric or specific nutrients from the diet, engaging in pathogenic weight control behaviors, and restricting fluids. These people often respond to pressures of the sport or activity, coaches, peers, or parents by adopting negative body images and unsafe practices to maintain an ideal body composition for the activity. We provide athletic trainers with recommendations for safe weight loss and weight maintenance in sport and exercise. Although safe weight gain is also a concern for athletic trainers and their athletes and clients, that topic is outside the scope of this position statement. Athletic trainers are often the source of nutrition information for athletes and clients; therefore, they must have knowledge of proper nutrition, weight management practices, and methods to change body composition. Body composition assessments should be done in the most scientifically appropriate manner possible. Reasonable and individualized weight and body composition goals should be identified by appropriately trained health care personnel (eg, athletic trainers, registered dietitians, physicians). In keeping with the American Dietetics Association (ADA) preferred nomenclature, this document uses the terms registered dietitian or dietician when referring to a food and nutrition expert who has met the academic and professional requirements specified by the ADA's Commission on Accreditation for Dietetics Education. In some cases, a registered nutritionist may have equivalent credentials and be the

Guidance notes : safe practice for the use of nuclear density meters

International Nuclear Information System (INIS)

2000-06-01

These 'Guidance notes' have been written to provide information for owners and users on the safe care and use of instruments containing radioactive materials used for the measurement of moisture content and/or density of materials. They give practical guidance on compliance with the requirements of radiation protection legislation and the 'Code of safe practice for the use of nuclear density meters, NRL C15'. Some of these instruments have been known as 'soil moisture gauges' and others as 'nuclear density meters' or just 'NDMs'. For simplicity, these 'Guidance notes' will follow industry terminology and use the term 'nuclear density meter'. Some parts of these 'Guidance notes' and of the 'Code, NRL C15' are relevant for users of asphalt gauges containing radioactive sources. These are normally laboratory bench instruments, and are not portable field instruments. Nevertheless, the radioactive sources used are similar to those used for moisture measurement and the safety implications are similar. The units of measurement of radioactivity and radiation dose are discussed in Appendix 1. Appendix 2 contains consent application forms while sample transport forms can be found in Appendix 3.

Full Text Available Natural User Interfaces (NUI is a relatively new area of research that aims to develop humancomputer interfaces, natural and intuitive, using voice commands, hand movements and gesture recognition, similar to communication between people which also implies body language and gestures. In this paper is presented a natural designed workspace which acquires the user's motion using a Leap Motion sensor and visualizes the CAD models using a CAVE-like 3D visualisation system. The user can modify complex CAD models using bimanual gesture commands in a 3D virtual environment. The developed bimanual gestures for rotate, pan, zoom and explode are presented. From the conducted experiments is established that Leap Motion NUI sensor provides an intuitive tool for design review of CAD models, performed even by users with no experience in CAD systems and virtual environments.

Optimal inverse magnetorheological damper modeling using shuffled frog-leaping algorithm–based adaptive neuro-fuzzy inference system approach

Directory of Open Access Journals (Sweden)

Xiufang Lin

2016-08-01

Full Text Available Magnetorheological dampers have become prominent semi-active control devices for vibration mitigation of structures which are subjected to severe loads. However, the damping force cannot be controlled directly due to the inherent nonlinear characteristics of the magnetorheological dampers. Therefore, for fully exploiting the capabilities of the magnetorheological dampers, one of the challenging aspects is to develop an accurate inverse model which can appropriately predict the input voltage to control the damping force. In this article, a hybrid modeling strategy combining shuffled frog-leaping algorithm and adaptive-network-based fuzzy inference system is proposed to model the inverse dynamic characteristics of the magnetorheological dampers for improving the modeling accuracy. The shuffled frog-leaping algorithm is employed to optimize the premise parameters of the adaptive-network-based fuzzy inference system while the consequent parameters are tuned by a least square estimation method, here known as shuffled frog-leaping algorithm-based adaptive-network-based fuzzy inference system approach. To evaluate the effectiveness of the proposed approach, the inverse modeling results based on the shuffled frog-leaping algorithm-based adaptive-network-based fuzzy inference system approach are compared with those based on the adaptive-network-based fuzzy inference system and genetic algorithm–based adaptive-network-based fuzzy inference system approaches. Analysis of variance test is carried out to statistically compare the performance of the proposed methods and the results demonstrate that the shuffled frog-leaping algorithm-based adaptive-network-based fuzzy inference system strategy outperforms the other two methods in terms of modeling (training accuracy and checking accuracy.

2016-12-01

Expression of peptide transporter 1 (PepT1) and liver-expressed antimicrobial peptide 2 (LEAP-2) in chickens can be influenced by food deprivation, pathological conditions and drug administration. Effect of three putative probiotic Lactobacillus strains and enrofloxacin on the expression of PepT1 and LEAP-2 mRNA was investigated in Ross 308 chickens. One-day-old chicks (n = 24) were allocated to following groups: control (without treatment); group treated with probiotics via feed; group treated with a combination of probiotics and enrofloxacin; and a group given enrofloxacin only. The drug was administered at a dose of 10 mg kg -1 , via drinking water for 5 days. Samples from liver, duodenum and jejunum were collected 126 h after the start of the treatment. Expression levels of PepT1 and LEAP-2 were determined by real-time polymerase chain reaction and were statistically evaluated by Mann-Whitney test. Enrofloxacin administered alone or in combination with probiotics provoked a statistically significant up-regulation of PepT1 mRNA levels in the measured organ sites. These changes can be attributed to a tendency of improvement in utilization of dietary peptide and in body weight gain. LEAP-2 mRNA expression levels did not change significantly in enrofloxacin-treated chickens in comparison with control group.

Diarrheal illness, frequently associated with fecal-oral transmission, is one of the leading causes of death worldwide. It is commonly preventable through the implementation of safe water practices. This experiment concerns how to best implement safe water practices in a quasi-permanent refugee camp setting with limited ability for structural changes. Specifically, we explore how health promotion activities that help identify target groups for hygiene interventions can play a role in disease prevention. An anonymous survey was conducted at the United Nations Relief and Works Agency Health Clinic in the Kulandia refugee camp to assess the safe water and personal hygiene practices. Demographic and social characteristics, accessible water and personal hygiene characteristics, and gastrointestinal (GI) burden for individuals and their households were assessed. A total of 96 individuals were enrolled; 62 females and 34 males. Approximately 58% of the sample had soap available and washed hands before and after eating and when preparing food. Piped water was the main source of drinking water (62%), while 31% of our sample utilized tanker-trucks. 93% of participants had access to toilet facilities, with 86% of these facilities being private households. 55% practice extra water hygiene measures on their household drinking water source. 51.3% considered vendor cleanliness when they were buying food. 51% had received formal health education. 68.8% had been taught by their parents, but only 55.2% were teaching their children and 15.6% had consistent access to a health professional for hygiene inquiries. Individual variables and hygiene practices associated with lower rates of diarrheal illnesses included having water piped into the home, proper hand washing, adequate soap availability, proper consideration of vendor cleanliness, higher income, levels of education, health hygiene education, and having access to healthcare professions to discuss hygiene related matters. This is

The Characters of Leap Years in Qing Calendars (1644-1911)

Science.gov (United States)

Lu, Dalong

In Qing Dynasty (1644-1911) three different calendars had been put into use which titles are Xiyang Xinfa Lishu (Treatise on Astronomy and Calendrical Science according to the New Method in West 1645-1666) Yuzhi Lixiang Kaocheng (Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1725-1742) and Yuzhi Lixiang Kaocheng Houbian (Sequel Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1742-1911). The characters of leap years in the three calendars are different for the last one which is selected the year of 1723 as it epoch and named as Guimao Yuan Li. This calendar is based on the 33-year pattern of leap years (there is a rather exact accord between days and years over this interval with eight days being intercalated per 33 years) and is slightly different from the former two calendars. Therefore the calendars of Qing Dynasty complied by Western Jesuits and Chinese astronomers can be regarded as the remarkable achievements in the history of calendar in the world.

2018-04-01

This paper proposed a novel puppet play method utilizing recent technology. An interactive puppet game has been developed based on the theme of a famous Chinese classical novel. This project was implemented using Unreal Engine, which is a leading software of integrated tools for developers to design and build games. On the other hand, Leap Motion Controller is a sensor device for recognizing hand movements and gestures. It is commonly used in systems which require close-range finger-based user interaction. In order to manipulate puppets’ movements, the developed program employs the Leap Motion SDK, which provides a friendly way to add motion-controlled 3D hands to an Unreal game. The novelty of our project is to replace 3D model of rigged hands by two 3D humanoid rigged characters. The challenges of this task are two folds. First, the skeleton structure of a human hand and a humanoid character (i.e., puppets) are totally different. Making the puppets to follow the hand poses of the user and yet ensuring reasonable puppets’ movements has not been discussed in the literatures nor in the developer forums. Second, there are only a limited number of built-in recognizable hand gestures. More recognizable hand gestures need to be created for the interactive game. This paper reports the proposed solutions to these challenges.

Leaping out of water is a phenomenon exhibited by a variety of aquatic and semi-aquatic animals, such as frogs and whales. In this study, we aim to elucidate the effects of geometric and kinematic conditions on the propulsive and drag force required for an animal to jump through the water interface. A simple mechanism was designed to measure the propulsive thrust produced by a flapping appendage. In a separate experiment to measure the opposing drag, simplified models of animals are 3D printed and fitted with pressure sensors. The model is accelerated from rest and covers a range of Re from 103 to 105. Using a high-speed camera and pressure sensors, we observed a deformation of the free surface prior to water exit, and correlated this to the drag force. Finally, we discuss a scaling law to describe the general physics which allow animals to leap out of water. NSF EAPSI.

The majority of the current surgical simulators employ specialized sensory equipment for instrument tracking. The Leap Motion controller is a new device able to track linear objects with sub-millimeter accuracy. The aim of this study was to investigate the potential of a virtual reality (VR) simulator for assessment of basic laparoscopic skills, based on the low-cost Leap Motion controller. A simple interface was constructed to simulate the insertion point of the instruments into the abdominal cavity. The controller provided information about the position and orientation of the instruments. Custom tools were constructed to simulate the laparoscopic setup. Three basic VR tasks were developed: camera navigation (CN), instrument navigation (IN), and bimanual operation (BO). The experiments were carried out in two simulation centers: MPLSC (Athens, Greece) and CRESENT (Riyadh, Kingdom of Saudi Arabia). Two groups of surgeons (28 experts and 21 novices) participated in the study by performing the VR tasks. Skills assessment metrics included time, pathlength, and two task-specific errors. The face validity of the training scenarios was also investigated via a questionnaire completed by the participants. Expert surgeons significantly outperformed novices in all assessment metrics for IN and BO (p assessment of basic laparoscopic skills. The proposed system allowed the evaluation of dexterity of the hand movements. Future work will involve comparison studies with validated simulators and development of advanced training scenarios on current Leap Motion controller.

Food-borne disease outbreaks remain a major global health challenge and cross-contamination from raw meat due to poor handling is a major cause in developing countries. Adequate knowledge of meat handlers is important in limiting these outbreaks. This study evaluated and compared the safe meat-handling knowledge, attitudes and practices (KAP) of private (PMPP) and government meat processing plants' (GMPP) workers in south-western Nigeria. This cross sectional study comprised 190 meat handlers (PMPP = 55; GMPP = 135). Data concerning their safe meat-handling knowledge, attitudes and practices as well as their socio-demographic characteristics, such as age, gender and work experience were collected. A significant association was observed between the type of meat processing plants and their knowledge (p = 0.000), attitudes (p = 0.000) and practices (p = 0.000) of safe meat-handling. Meat handlers in the GMPP were respectively, about 17 times (OR = 0.060, 95% CI: 0.018-0.203), 57 times (OR = 0.019, 95% CI: 0.007-0.054) and 111 times (OR = 0.009, 95% CI: 0.001- 0.067) less likely to obtain good knowledge, attitude and practice level of safe meat-handling than those from PMPP. Further, KAP levels were significantly associated with age group, education and work experience (p < 0.05). Study findings suggest the need for future policy in food industry in developing countries to accommodate increased involvement of private sector for improved food safety and quality delivery. Public health education on safe food handling and hygiene should be on the front burner among food handlers in general.

Practical exercises are a crucial part of many curricula. Even simple exercises can improve the understanding of the underlying subject. Most experimental setups require special hardware. To carry out e. g. a lens experiments the students need access to an optical bench, various lenses, light sources, apertures and a screen. In our previous publication we demonstrated the use of augmented reality visualization techniques in order to let the students prepare with a simulated experimental setup. Within the context of our intended blended learning concept we want to utilize augmented or virtual reality techniques for stationary laboratory exercises. Unlike applications running on mobile devices, stationary setups can be extended more easily with additional interfaces and thus allow for more complex interactions and simulations in virtual reality (VR) and augmented reality (AR). The most significant difference is the possibility to allow interactions beyond touching a screen. The LEAP Motion controller is a small inexpensive device that allows for the tracking of the user's hands and fingers in three dimensions. It is conceivable to allow the user to interact with the simulation's virtual elements by the user's very hand position, movement and gesture. In this paper we evaluate possible applications of the LEAP Motion controller for simulated experiments in augmented and virtual reality. We pay particular attention to the devices strengths and weaknesses and want to point out useful and less useful application scenarios.

Construction in and around a working perioperative suite is a challenge beyond merely managing traffic patterns and maintaining the sterile field. The AORN "Recommended practices for a safe environment of care, part II" provides guidance on building design; movement of patients, personnel, supplies, and equipment; environmental controls; safety and security; and control of noise and distractions. Whether the OR suite evolves through construction, reconstruction, or remodeling, a multidisciplinary team of construction experts and health care professionals should create a functional plan and communicate at every stage of the project to maintain a safe environment and achieve a well-designed outcome. Emergency preparedness, a facility-wide security plan, and minimization of noise and distractions in the OR also help enhance the safety of the perioperative environment. Copyright © 2014 AORN, Inc.

China's dual employment system plays a crucial role in sexually transmitted infections (STIs) and HIV-related safe and unsafe sexual practices among young Chinese people. Social and psychological determinants of safe and unsafe sexual practices for HIV infection among young people in Sichuan, China were examined. Our findings indicate that changes in China's social structure and employment system impact upon the social contextual involvement and socio-sexual practice of young Chinese people. The findings in the study suggest that the employment-related contextual involvement was a major predictor in the relationships between demography, information, and psychological risk-taking factors on one hand and the people's safe and unsafe sexual practices on the other. Self-employed people (officially called 'getihu') were more likely than the state-employed people to engage in unprotected sex with casual sexual partners. As China undergoes social restructuring and many state-employed people are laid off, the risk may also extend into the broader non-self-employed population as more state-employed people become involved not only in the self-employed getihu's socioeconomic activities but also in their unconventional socio-sexual practices. Collective vulnerability to STI and HIV, due to the current socio-sexual practices of the getihu young people, has created a new frontier for STI and HIV prevention in today's China, as well as demonstrating the importance of collective action with STI and AIDS prevention strategies within relevant social and sub-cultural contexts.

The concentrations of Cr, Cu, Fe, Mn, Ni, Pb, Cd, and Zn were determined in the brain, heart, liver, gill, gonad, spleen, kidney, and red and white muscles of Liza saliens (leaping mullet). Trace element levels in fish samples were analyzed by flame atomic absorption spectrometry. Among the non-essential metals, the levels of Ni and Pb in the tissues were higher than limits for fish proposed by FAO/WHO, EU, and TFC. Generally, the levels of the non-essential metals were much higher than those of manganese in the red and white muscles. Fe distribution pattern in tissues was in order of spleen > liver > heart > gill > brain > kidney > gonad > red muscle > white muscle. Red muscle was not within the safe limits for human consumption because non-essential metal (Ni, Pb) contents were higher than standard limits.

The long-term forecasting of energy supply and demand is an extremely important topic of fundamental research in Taiwan due to Taiwan's lack of natural resources, dependence on energy imports, and the nation's pursuit of sustainable development. In this article, we provide an overview of energy supply and demand in Taiwan, and a summary of the historical evolution and current status of its energy policies, as background to a description of the preparation and application of a Long-range Energy Alternatives Planning System (LEAP) model of Taiwan's energy sector. The Taiwan LEAP model is used to compare future energy demand and supply patterns, as well as greenhouse gas emissions, for several alternative scenarios of energy policy and energy sector evolution. Results of scenarios featuring 'business-as-usual' policies, aggressive energy-efficiency improvement policies, and on-schedule retirement of Taiwan's three existing nuclear plants are provided and compared, along with sensitivity cases exploring the impacts of lower economic growth assumptions. A concluding section provides an interpretation of the implications of model results for future energy and climate policies in Taiwan. - Research highlights: → The LEAP model is useful for international energy policy comparison. → Nuclear power plants have significant, positive impacts on CO 2 emission. → The most effective energy policy is to adopt demand-side management. → Reasonable energy pricing provides incentives for energy efficiency and conservation. → Financial crisis has less impact on energy demand than aggressive energy policy.

Towards automatic global error control: Computable weak error expansion for the tau-leap method

KAUST Repository

Karlsson, Peer Jesper; Tempone, Raul

2011-01-01

This work develops novel error expansions with computable leading order terms for the global weak error in the tau-leap discretization of pure jump processes arising in kinetic Monte Carlo models. Accurate computable a posteriori error approximations are the basis for adaptive algorithms, a fundamental tool for numerical simulation of both deterministic and stochastic dynamical systems. These pure jump processes are simulated either by the tau-leap method, or by exact simulation, also referred to as dynamic Monte Carlo, the Gillespie Algorithm or the Stochastic Simulation Slgorithm. Two types of estimates are presented: an a priori estimate for the relative error that gives a comparison between the work for the two methods depending on the propensity regime, and an a posteriori estimate with computable leading order term. © de Gruyter 2011.

The sodium-water reaction event in an FBR steam generator (SG) has influence on the safety, economical efficiency, etc. of the plant, so that the selection of design base leak (DBL) of the SG is considered as one of the important matters. The clarification of the sodium-water reaction phenomenon and the development of an analysis model are necessary to estimate the sodium-water reaction event with high accuracy and rationality in selecting the DBL. The reaction jet model is pointed out as a part of the necessary improvements to evaluate the overheating tube rupture of large SGs, since the behavior of overheating tube rupture is largely affected by the reaction jet conditions outside the tube. Therefore, LEAP-JET has been developed as an analysis code for the simulation of sodium-water reactions. This document shows the validation of the LEAP-JET code by the Sodium-Water Reaction Test (SWAT-1R). The following results have been obtained: (1) The reaction rate constant, K, is estimated at between 0.001≤K≤0.1 from the LEAP-JET analysis of the SWAT-1R data. (2) The analytical results on the high-temperature region and the behaviors of reaction consumption (Na, H 2 O) and products (H 2 , NaOH, Na 2 O) are considered to be physically reasonable. (3) The LEAP-JET analysis shows the tendency of overestimation in the maximum temperature and temperature distribution of the reaction jet. (4) In the LEAP-JET analysis, the numerical calculation becomes unstably, especially in the mesh containing quite small sodium mass. Therefore, it is necessary to modify the computational algorism to stabilize it and obtain the optimum value of K in sodium-water reactions. (author)

Multilevel Drift-Implicit Tau-Leap

KAUST Repository

2016-01-06

The dynamics of biochemical reactive systems with small copy numbers of one or more reactant molecules is dominated by stochastic effects. For those systems, discrete state-space and stochastic simulation approaches were proved to be more relevant than continuous state-space and deterministic ones. In systems characterized by having simultaneously fast and slowtimescales, the existing discrete space-state stochastic path simulation methods such as the stochastic simulation algorithm (SSA) and the explicit tauleap method can be very slow. Implicit approximations were developed in the literature to improve numerical stability and provide efficient simulation algorithms for those systems. In this work, we propose an efficient Multilevel Monte Carlo method in the spirit of the work by Anderson and Higham (2012) that uses drift-implicit tau-leap approximations at levels where the explicit tauleap method is not applicable due to numerical stability issues. We present numerical examples that illustrate the performance of the proposed method.

Interglacial-glacial transitions represent important turnovers in the climate system. In contrast with glacial terminations, they are described as a more gradual cooling. So far, the last interglacial has yielded a wealth of knowledge regarding climate dynamics during past warm periods. On top of the assumed gradual temperature drop starting at 119 ka, evidence for the presence of a drastic drying/cooling event in northern Europe has been observed. In lake records from Germany, a distinct shift in pollen assembly at 117.5 ka is interpreted as the consequence of a short dry event lasting 470 years, defined as the Late Eemian Aridity Pulse (LEAP, Sirocko et al., 2005). In a Belgian stalagmite from Han-sur-Lesse Cave, the LEAP is characterized by a 5‰ increase in δ13C occurring in just 200 years. The δ13C enrichment is dated at 117.5 ka and associated with a vegetation change above the cave, induced by a drying and/or cooling event (Vansteenberge et al., 2016). Also, within North Atlantic sediment cores, an increase in ice rafted debris was linked to the occurrence of a colder period at 117 ka (Irvali et al., 2016). Its coevality with the LEAP indicates a likely more regional extent than previously thought. Up to now, no independent chronology exists and little is known about the continental climatic expression of the LEAP. This study aims at 1) constructing an improved and independent chronology for the LEAP event, 2) characterizing this event in terms of its climatic expression and 3) placing the LEAP within the context of an interglacial-glacial transition. For this, two additional speleothems (Han-8, RSM-17) from two different Belgian caves (Han-sur-Lesse, Remouchamps) are added to the existing Han-9 dataset. Exceptionally high growth rates (0.5 mm yr-1) and a presumed annual layering of the RSM-17 sample enable an annual to decadal resolution to investigate the LEAP. U-Th age models covering the glacial inception are constructed with 25 dates on the three

Flying fish can both swim underwater and glide in air. Transitioning from swimming to gliding requires penetration of the air-water interface, or breaking the ``surface tension barrier,'' a formidable task for juvenile flying fish measuring 1 to 5 cm in length. In this experimental investigation, we use high-speed videography to characterize the kinematics of juvenile flying fish as they leap from the water surface. During this process, which lasts 0.05 seconds, flying fish achieve body accelerations of 5 times earth's gravity and gliding speeds of 1.3 m/s, an order of magnitude higher than their steady swimming speed. We rationalize this anomalously high speed on the basis of the hydrodynamic and surface tension forces and torques experienced by the fish. Specifically, leaping fish experience skin friction forces only on the submerged part of their body, permitting them to achieve much higher speeds than in steady underwater swimming. We also perform experiments using a towed flying fish mimc to determine optimality of various parameters in this process, including body angle and start position with respect to the water surface.

Nowadays, routine cross-sectional imaging viewing during a surgical procedure requires physical contact with an interface (mouse or touch-sensitive screen). Such contact risks exposure to aseptic conditions and causes loss of time. Devices such as the recently introduced Leap Motion (Leap Motion Society, San Francisco, CA), which enables interaction with the computer without any physical contact, are of wide interest in the field of surgery, but configuration and ergonomics are key challenges for the practitioner, imaging software, and surgical environment. This article aims to suggest an easy configuration of Leap Motion on a PC for optimized use with Carestream Vue PACS v11.3.4 (Carestream Health, Inc, Rochester, NY) using a plug-in (to download at https://drive.google.com/open?id=0B_F4eBeBQc3yNENvTXlnY09qS00&authuser=0) and a video tutorial (https://www.youtube.com/watch?v=yVPTgxg-SIk).

Food safety training has been the primary avenue for ensuring food workers are performing proper food handling practices and thus, serving safe food. Yet, knowledge of safe food handling practices does not necessarily result in actual performance of these practices. This research identified participating food service employees' level of agreement with four factors of motivation (internal motivations, communication, reward-punishment, and resources) and determined if respondents with different demographic characteristics reported different motivating factors. Data were collected from 311 food service employees who did not have any supervisory responsibilities. Intrinsic motivation agreement scores were consistently the highest of all four motivational factors evaluated and did not differ across any of the demographic characteristics considered. In contrast, motivation agreement scores for communication, reward-punishment, and resources did differ based on respondents' gender, age, place of employment, job status, food service experience, completion of food handler course, or possession of a food safety certification. In general, respondents agreed that these motivation factors influenced their likelihood to perform various safe food handling procedures. This research begins to illustrate how employees' demographic characteristics influence their responses to various motivators, helping to clarify the complex situation of ensuring safe food in retail establishments. Future research into why employee willingness to perform varies more for extrinsic motivation than for intrinsic motivation could assist food service managers in structuring employee development programs and the work environment, in a manner that aids in improving external motivation (communication, reward-punishment, and resources) and capitalizing on internal motivation.

The purpose of this study was to develop guidelines for Korean consumers with regard to safe food handling practices at home by identifying current food handling issues. Korean consumers' behaviors regarding their safe food handling were identified via survey questionnaires that included items on individual hygiene practices, prepreparation steps when cooking, the cooking process, and the storage of leftover foods. The subjects were 417 Korean parents with elementary school children living in Seoul and Gyeonggi Province in the central area of Korea. The survey results revealed gaps between the knowledge or practices of Korean consumers and scientific evidence pertaining to safe food handling practices. Based on these findings, a leaflet on safe food handling guidelines was developed in accordance with Korean food culture. These guidelines suggest personal hygiene practices as well as fundamental principles and procedures for safe food handling from the stage of food purchase to that of keeping leftover dishes. A pilot application study with 50 consumers revealed that the guidelines effectively improved Korean consumers' safe food handling practices, suggesting that they can serve as practical educational material suitable for Korean consumers.

Breast and cervical cancers are the most common causes of cancer mortality among women in India, but actually they are largely preventable diseases. Although early detection is the only way to reduce morbidity and mortality, there are limited data on breast and cervical cancer knowledge, safe practices and attitudes of teachers in India. The purpose of this study is to assess the level of awareness and impact of awareness programs in adoption of safe practices in prevention and early detection. This assessment was part of a pink chain campaign on cancer awareness. During cancer awareness events in 2011 at various women colleges in different parts in India, a pre-test related to cervical cancer and breast cancer was followed by an awareness program. Post-tests using the same questionnaire were conducted at the end of the interactive session, at 6 months and 1 year. A total of 156 out of 182 teachers participated in the study (overall response rate was 85.7 %). Mean age of the study population was 42.4 years (range- 28-59 yrs). There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of breast self examination (BSE) was significantly more frequent in comparison to CBE, mammography and the Pap test. Magazines and newspapers were sources for knowledge regarding screening tests for breast cancer in more than 60% of teachers where as more than 75% were educated by doctors regarding the Pap test. Post awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons for not doing screening test were found to be ignorance (50%), lethargic attitude (44.8%) and lack of time (34.6%). Level of knowledge of breast cancer risk factors, symptoms and screening methods was high as compared to cervical cancer. There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year

oscillating light `waves' had to be quantized as well. Several articles in this issue of Physics Education celebrate the first year of the quantum, 1900. I am grateful and beholden to Board Member and co-editor Gren Ireson for his contacts and nomination of the various contributors. It does seem strange, however, a full century after its discovery full of its amazing success that the essential quantum nature of practically everything is still kept hidden from school students, in the UK at least. Let's see what happens in the coming century. Now for another quantum leap. This is the last issue of Physics Education that I shall have the honour of editing. In fact, I shall leap into historical obscurity as the very last honorary editor. Great efforts by your Editorial Board - over a fair number of years! - have resulted in a radical reorganizing of both the journal and the way it is produced. It's been an interesting five years, a time of falling numbers but quite radical innovations in post-16 physics education. IoPP and the IoP are working together to revitalize what may have been seen by many as a staid if respectable and authoritative publication. We shall keep the authority and even respectability but hope to liven things up a bit. The new editor is Kerry Parker of Sheffield College. She will take on a stronger role than I and my predecessors have had, and will be working at IoPP in Bristol two days a week.

When a stream of shampoo is fed onto a pool in one's hand, a jet can leap sideways or rebound from the liquid surface in an intriguing phenomenon known as the Kaye effect. Earlier studies have debated whether non-Newtonian effects are the underlying cause of this phenomenon, making the jet glide on top of a shear-thinning liquid layer, or whether an entrained air layer is responsible. Herein we show unambiguously that the jet slides on a lubricating air layer. We identify this layer by looking through the pool liquid and observing its rupture into fine bubbles. The resulting microbubble sizes suggest this air layer is of submicron thickness. This thickness estimate is also supported by the tangential deceleration of the jet during the rebounding.

2015-01-01

The uptake of stereotactic ablative body radiation therapy (SABR) / stereotactic body radiation therapy (SBRT) worldwide has been rapid. The Australian and New Zealand Faculty of Radiation Oncology (FRO) assembled an expert panel of radiation oncologists, radiation oncology medical physicists and radiation therapists to establish guidelines for safe practice of SABR. Draft guidelines were reviewed by a number of international experts in the field and then distributed through the membership of the FRO. Members of the Australian Institute of Radiography and the Australasian College of Physical Scientists and Engineers in Medicine were also asked to comment on the draft. Evidence-based recommendations (where applicable) address aspects of departmental staffing, procedures and equipment, quality assurance measures, as well as organisational considerations for delivery of SABR treatments. Central to the guidelines is a set of key recommendations for departments undertaking SABR. These guidelines were developed collaboratively to provide an educational guide and reference for radiation therapy service providers to ensure appropriate care of patients receiving SABR.

It invests in a fundamental TRL 1-6 research and technology portfolio that will enable the future of: Alternative fuels and/or alternative propulsion systems, non-combustion (electric) propulsion systems. P&P/LEAP will identify and capitalize on the highest potential concepts generated both internal and external to the Agency. During my 2004 summer at NASA Glenn Research Center, I worked with my mentor Barbara Mader, in the Project Office with the Business Team completing various tasks for the project and personnel. The LEAP project is a highly matrixed organization. The Project Office is responsible for the goals advocacy and dollar (budget) of the LEAP project. The objectives of the LEAP Project are to discover new energy sources and develop unconventional engines and power systems directed towards greatly reduced emissions, enable new vehicle concepts for public mobility, new science missions and national security. The Propulsion and PowerLow Emissions Alternative Power directly supports the environmental, mobility, national security objectives of the Vehicle Systems Program and the Aeronautics Technology Theme. Technology deliverables include the demonstration through integrated ground tests, a constant volume combustor in an engine system, and UAV/small transport aircraft all electric power system. My mentor serves as a key member of the management team for the Aeropropulsion Research Program Office (ARPO). She has represented the office on numerous occasions, and is a member of a number of center-wide panels/teams, such as the Space management Committee and is chair to the Business Process Consolidation Team. She is responsible for the overall coordination of resources for the Propulsion and Power Project - from advocacy to implementation. The goal for my summer at NASA was to document processes and archive program documents from the past

2013-03-14

The stochastic integral ensuring the Newton-Leibnitz chain rule is essential in stochastic energetics. Marcus canonical integral has this property and can be understood as the Wong-Zakai type smoothing limit when the driving process is non-Gaussian. However, this important concept seems not well-known for physicists. In this paper, we discuss Marcus integral for non-Gaussian processes and its computation in the context of stochastic energetics. We give a comprehensive introduction to Marcus integral and compare three equivalent definitions in the literature. We introduce the exact pathwise simulation algorithm and give the error analysis. We show how to compute the thermodynamic quantities based on the pathwise simulation algorithm. We highlight the information hidden in the Marcus mapping, which plays the key role in determining thermodynamic quantities. We further propose the tau-leaping algorithm, which advance the process with deterministic time steps when tau-leaping condition is satisfied. The numerical experiments and its efficiency analysis show that it is very promising.

Some countries have accumulated considerable experience in the operation of these reactors and have in the process developed safe practices. On the other hand, other countries which have recently acquired, or will soon acquire, such reactors do not have sufficient background of experience with them to have developed full knowledge regarding their safe operation. In this situation, the International Atomic Energy Agency has considered that it would be useful to make available to all its Member States a set of recommendations on the safe operation of these reactors, based on the accumulated experience and best practices. The Director General accordingly nominated a Pane Ion Safe Operation of Critical Assemblies and Research Reactors to assist the Agency's Secretariat in drafting such recommendations

Mobile technology is one way that we have reached this population with safer sex information but challenges exist with the delivery process. The literature between 2010 and 2015 was reviewed for data on safe sex and sexual health information delivered using mobile cell phone devices. A search for relevant databases revealed that 17 articles met our inclusion criteria. Findings suggest that mobile cell phone interventions are an effective mode for delivering safe sex and sexual health information to youth; those at the highest risk may not be able to access cell phones based on availability and cost of the text messages or data plans.

Shuffled Frog Leaping Algorithm for Preemptive Project Scheduling Problems with Resource Vacations Based on Patterson Set

Directory of Open Access Journals (Sweden)

Yi Han

2013-01-01

Full Text Available This paper presents a shuffled frog leaping algorithm (SFLA for the single-mode resource-constrained project scheduling problem where activities can be divided into equant units and interrupted during processing. Each activity consumes 0–3 types of resources which are renewable and temporarily not available due to resource vacations in each period. The presence of scarce resources and precedence relations between activities makes project scheduling a difficult and important task in project management. A recent popular metaheuristic shuffled frog leaping algorithm, which is enlightened by the predatory habit of frog group in a small pond, is adopted to investigate the project makespan improvement on Patterson benchmark sets which is composed of different small and medium size projects. Computational results demonstrate the effectiveness and efficiency of SFLA in reducing project makespan and minimizing activity splitting number within an average CPU runtime, 0.521 second. This paper exposes all the scheduling sequences for each project and shows that of the 23 best known solutions have been improved.

Full Text Available Hand rehabilitation is fundamental after stroke or surgery. Traditional rehabilitation requires a therapist and implies high costs, stress for the patient, and subjective evaluation of the therapy effectiveness. Alternative approaches, based on mechanical and tracking-based gloves, can be really effective when used in virtual reality (VR environments. Mechanical devices are often expensive, cumbersome, patient specific and hand specific, while tracking-based devices are not affected by these limitations but, especially if based on a single tracking sensor, could suffer from occlusions. In this paper, the implementation of a multi-sensors approach, the Virtual Glove (VG, based on the simultaneous use of two orthogonal LEAP motion controllers, is described. The VG is calibrated and static positioning measurements are compared with those collected with an accurate spatial positioning system. The positioning error is lower than 6 mm in a cylindrical region of interest of radius 10 cm and height 21 cm. Real-time hand tracking measurements are also performed, analysed and reported. Hand tracking measurements show that VG operated in real-time (60 fps, reduced occlusions, and managed two LEAP sensors correctly, without any temporal and spatial discontinuity when skipping from one sensor to the other. A video demonstrating the good performance of VG is also collected and presented in the Supplementary Materials. Results are promising but further work must be done to allow the calculation of the forces exerted by each finger when constrained by mechanical tools (e.g., peg-boards and for reducing occlusions when grasping these tools. Although the VG is proposed for rehabilitation purposes, it could also be used for tele-operation of tools and robots, and for other VR applications.

We previously postulated how evolutionary changes in man's upper respiratory tract to facilitate speech, a phenomenon Jared Diamond calls The Great Leap Forward, have predisposed man to obstructive sleep apnea (OSA) [Diamond J. The Third Chimpanzee: the evolution and future of the human animal. New York: HarperCollins Publishers; 1992. p. 21, 23, 32-54, 54-6; Davidson TM. The Great Leap Forward: the anatomic evolution of obstructive sleep apnea. Sleep Medicine 2003;4:185-94]. We grouped these anatomic changes into four categories: klinorynchy, laryngeal descent, craniobase angulation and supralaryngeal vocal tract (SVT) ratio of SVT(H):SVT(V). This study was designed to investigate the relationship between cephalometric measures corresponding to these anatomic changes and OSA. One hundred and twenty-three male subjects presenting with symptoms of OSA underwent unattended multi-channel home sleep studies. We obtained cephalometric measurements from standard lateral cephalograms. Pearson correlation coefficients were calculated between cephalometrics and apnea-hypopnea index (AHI), age, and body mass index (BMI). Our results showed significant correlation between AHI and klinorynchy, laryngeal descent, and craniobase angulation. Overall, our data supports the theory that evolutionary anatomic changes to facilitate speech correlate with OSA severity. The cumulative changes in each cephalometric category trended in the directions hypothesized and support the Great Leap theory of OSA evolution.

Full Text Available The transient radiative transfer in 1-D homogeneous media with ultra-short Gaussian pulse laser irradiated was investigation by the finite volume method. The concept of optimal detection distance was proposed. The radiation characteristic was studied thoroughly. Afterwards, a memetic meta-heuristic shuffled frog leaping algorithm was introduced to inverse transient radiative problems. It is demonstrated that the extinction coefficient and scattering albedo can be retrieved accurately even with noisy data in a homogeneous absorbing and isotropic scattering plane-parallel slab. Finally, a technique was proposed to accelerate the inverse process by reducing the searching space of the radiative parameters.

Forecasting of Energy Consumption in China Based on Ensemble Empirical Mode Decomposition and Least Squares Support Vector Machine Optimized by Improved Shuffled Frog Leaping Algorithm

Full Text Available For social development, energy is a crucial material whose consumption affects the stable and sustained development of the natural environment and economy. Currently, China has become the largest energy consumer in the world. Therefore, establishing an appropriate energy consumption prediction model and accurately forecasting energy consumption in China have practical significance, and can provide a scientific basis for China to formulate a reasonable energy production plan and energy-saving and emissions-reduction-related policies to boost sustainable development. For forecasting the energy consumption in China accurately, considering the main driving factors of energy consumption, a novel model, EEMD-ISFLA-LSSVM (Ensemble Empirical Mode Decomposition and Least Squares Support Vector Machine Optimized by Improved Shuffled Frog Leaping Algorithm, is proposed in this article. The prediction accuracy of energy consumption is influenced by various factors. In this article, first considering population, GDP (Gross Domestic Product, industrial structure (the proportion of the second industry added value, energy consumption structure, energy intensity, carbon emissions intensity, total imports and exports and other influencing factors of energy consumption, the main driving factors of energy consumption are screened as the model input according to the sorting of grey relational degrees to realize feature dimension reduction. Then, the original energy consumption sequence of China is decomposed into multiple subsequences by Ensemble Empirical Mode Decomposition for de-noising. Next, the ISFLA-LSSVM (Least Squares Support Vector Machine Optimized by Improved Shuffled Frog Leaping Algorithm model is adopted to forecast each subsequence, and the prediction sequences are reconstructed to obtain the forecasting result. After that, the data from 1990 to 2009 are taken as the training set, and the data from 2010 to 2016 are taken as the test set to make an

Wind-powered wheel locomotion, initiated by leaping somersaults, in larvae of the southeastern beach tiger beetle (Cicindela dorsalis media.

Directory of Open Access Journals (Sweden)

Alan Harvey

2011-03-01

Full Text Available Rapid movement is challenging for elongate, soft-bodied animals with short or no legs. Leaping is known for only a few animals with this "worm-like" morphology. Wheel locomotion, in which the animal's entire body rolls forward along a central axis, has been reported for only a handful of animals worldwide. Here we present the first documented case of wind-powered wheel locomotion, in larvae of the coastal tiger beetle Cicindela dorsalis media. When removed from their shallow burrows, larvae easily can be induced to enter a behavioral sequence that starts with leaping; while airborne, larvae loop their body into a rotating wheel and usually either "hit the ground rolling" or leap again. The direction larvae wheel is closely related to the direction in which winds are blowing; thus, all our larvae wheeled up-slope, as winds at our study site consistently blew from sea to land. Stronger winds increased both the proportion of larvae wheeling, and the distance traveled, exceeding 60 m in some cases. In addition, the proportion of larvae that wheel and the distance traveled by wheeling larvae are significantly greater on smooth sandy beaches than on beach surfaces made rough and irregular by pedestrian, equestrian, and vehicular traffic. Like other coastal species of tiger beetles, C. dorsalis media has suffered major declines in recent years that are clearly correlated with increased human impacts. The present study suggests that the negative effects of beach traffic may be indirect, preventing larvae from escaping from predators using wheel locomotion by disrupting the flat, hard surface necessary for efficient wheeling.

A research associated with urban transportation was carried out in Rawalpindi and Islamabad to analyze the status of emission of air pollutants and energy demands. The study included a discussion of past trends and future scenarios in order to reduce the future emissions. A simple model of passenger transport has been developed using computer based software called Long-Range Energy Alternatives Planning System (LEAP). The LEAP model was used to estimate total energy demand and the vehicular emissions for the base year 2000 and extrapolated till 2030 for the future predictions. Transport database in Rawalpindi and Islamabad, together with fuel consumption values for the vehicle types and emission factors of NO{sub x}, SO{sub 2} and PM{sub 10} corresponding to the actual vehicle types, formed the basis of the transport demand, energy consumption and total emission calculations. Apart from base scenario, the model was run under three alternative scenarios to study the impact of different urban transport policy initiatives that would reduce energy demand and emissions in transport sector of Rawalpindi and Islamabad. The prime objective was to arrive at an optimal transport policy, which limits the future growth of fuel consumption as well as air pollution. (author)

To explore chronic obstructive pulmonary disease patients' experiences with a partnership-based nursing practice programme in the home setting. Patients with chronic obstructive pulmonary disease suffer from psychological and physiological problems, especially when they return home after hospitalisation from exacerbation. Many express a need for information and knowledge about chronic obstructive pulmonary disease. Partnership as practice is a patient-centred framework providing an individualised practice for each patient. This study intends to achieve a nuanced and improved understanding of chronic obstructive pulmonary disease patients' experiences with a partnership-based nursing practice programme comprising home visits from a respiratory nurse after hospital discharge, alongside interdisciplinary collaboration. This study has a qualitative design with interviews. Six individual semi-structured interviews collected in 2012-2013 constitute the material. Interviews were recorded, transcribed to written text and analysed using systematic text condensation. Three key themes were identified: to be seen, talked with and understood; healthcare support at home-continuity, practical support and facilitation; and exchange of knowledge. However, there were two generic themes that permeated the material: feeling safe and comforted, and motivation to achieve better health. Patients with chronic obstructive pulmonary disease can experience feeling safe and comforted, and be motivated to make changes in order to achieve better health after participating in a partnership-based nursing practice programme that includes home visits from a respiratory nurse and interdisciplinary cooperation after hospital discharge. To feel safe is of great importance, and how this relates to the patient's ability to cope with illness should be explored in further research. The results suggest that the partnership-based nursing practice programme that includes home visits and interdisciplinary

A syncopated leap-frog algorithm for orbit consistent plasma simulation of materials processing reactors

1994-01-01

The authors present a particle algorithm to extend simulation capabilities for plasma based materials processing reactors. The orbit integrator uses a syncopated leap-frog algorithm in cylindrical coordinates, which maintains second order accuracy, and minimizes computational complexity. Plasma source terms are accumulated orbit consistently directly in the frequency and azimuthal mode domains. Finally they discuss the numerical analysis of this algorithm. Orbit consistency greatly reduces the computational cost for a given level of precision. The computational cost is independent of the degree of time scale separation

Taking the leap toward a career as a private practice owner is daunting. When in the initial stages of starting a private practice, I searched for current advice from an audiologist who had recently confronted the same challenges I was about to face. Because of the limited information available, I documented my process in hopes of providing an overview of my startup experience to help others. Included is a timeline of startup tasks and a sample budget to use as a reference. In this chapter, I share my experiences, both the positives and the negatives, and tips with the goal of helping you survive and thrive in your first year in private practice. PMID:28028322

Safe injection practices for administration of propofol.

King, Cecil A; Ogg, Mary

Sepsis and postoperative infection can occur as a result of unsafe practices in the administration of propofol and other injectable medications. Investigations of infection outbreaks have revealed the causes to be related to bacterial growth in or contamination of propofol and unsafe medication practices, including reuse of syringes on multiple patients, use of single-use medication vials for multiple patients, and failure to practice aseptic technique and adhere to infection control practices. Surveys conducted by AORN and other researchers have provided additional information on perioperative practices related to injectable medications. In 2009, the US Food and Drug Administration and the Centers for Disease Control and Prevention convened a group of clinicians to gain a better understanding of the issues related to infection outbreaks and injectable medications. The meeting participants proposed collecting data to persuade clinicians to adopt new practices, developing guiding principles for propofol use, and describing propofol-specific, site-specific, and practitioner-specific injection techniques. AORN provides resources to help perioperative nurses reduce the incidence of postoperative infection related to medication administration. Copyright © 2012 AORN, Inc. Published by Elsevier Inc.

; further, self-reports of the intention to drive safely (or not) are socially sensitive. Therefore, we examined automatic preferences towards safe and risky driving with a Go/No-go Association Task (GNAT). The results suggest that (1) implicit attitudes towards driving behavior can be measured reliably...... with the GNAT; (2) implicit attitudes towards safe driving versus towards risky driving may be separable constructs. We propose that research on driving behavior may benefit from routinely including measures of implicit cognition. A practical advantage is a lesser susceptibility to social desirability biases......, compared to self-report methods. Pending replication in future research, the apparent dissociation between implicit attitudes towards safe versus risky driving that we observed may contribute to a greater theoretical understanding of the causes of unsafe and risky driving behavior....

Safe handling of tritium

International Nuclear Information System (INIS)

1991-01-01

The main objective of this publication is to provide practical guidance and recommendations on operational radiation protection aspects related to the safe handling of tritium in laboratories, industrial-scale nuclear facilities such as heavy-water reactors, tritium removal plants and fission fuel reprocessing plants, and facilities for manufacturing commercial tritium-containing devices and radiochemicals. The requirements of nuclear fusion reactors are not addressed specifically, since there is as yet no tritium handling experience with them. However, much of the material covered is expected to be relevant to them as well. Annex III briefly addresses problems in the comparatively small-scale use of tritium at universities, medical research centres and similar establishments. However, the main subject of this publication is the handling of larger quantities of tritium. Operational aspects include designing for tritium safety, safe handling practice, the selection of tritium-compatible materials and equipment, exposure assessment, monitoring, contamination control and the design and use of personal protective equipment. This publication does not address the technologies involved in tritium control and cleanup of effluents, tritium removal, or immobilization and disposal of tritium wastes, nor does it address the environmental behaviour of tritium.

2010-01-01

Approximately one-fifth of Western Australian women deliver their babies in rural and remote regions of the state. The medical workforce caring for these women is predominantly non-specialist GP obstetricians. This article explores how safe is rural GP obstetrics. It reviews one rural obstetric practice in detail. In particular it asks these questions: What are the antenatal risk factors? What are the obstetric outcomes for the mother? What are the obstetric outcomes for the baby? This study is an audit of the author's obstetric practice over a two-year period from July 2007 to June 2009. The audit criteria included all obstetric patients managed by the author through to delivery and immediate post-partum care. Hospital and practice notes for 195 singleton pregnancies were reviewed. Antenatal risk factors, intrapartum events and immediate post-partum events for all patients cared for by the author through to delivery were recorded and compared with averages for Western Australia from published 2007 figures. The maternal population had mean age of 28.5 years, 2.1% were Aboriginal. Body mass index (BMI) at booking was a mean of 27.1 (range 18-40). Those with a BMI > 40 were referred elsewhere. Significant antenatal risks included smoking (14.9%), previous caesarean section (14.4%), hypertension (13.3%), pre-eclampsia (5.1%) and gestational diabetes (8.2%). Intrapartum there were high rates of induction (33.5%), epidural/spinal (34.7%) and shoulder dystocia (3.6%). Type of delivery was predominantly spontaneous vaginal (65.6%), vacuum (14.9%), forceps (2.6%), elective caesarean (9.7%) and non-elective caesarean (8.7%). Post-partum events included post-partum haemorrhage (10.3%), transfusion (1.5%), retained placenta (2.1%), neonatal jaundice (21.1%), neonatal seizures (1.5%) neonatal sepsis (1.5%) and neonatal special care or intensive care (SCU/NICU) admission (9.8%). The audit population was a group of relatively low risk pregnant women. Despite referral of more

LEAP into the Pfizer Global Virtual Library (PGVL) space: creation of readily synthesizable design ideas automatically.

2011-01-01

Pfizer Global Virtual Library (PGVL) of 10(13) readily synthesizable molecules offers a tremendous opportunity for lead optimization and scaffold hopping in drug discovery projects. However, mining into a chemical space of this size presents a challenge for the concomitant design informatics due to the fact that standard molecular similarity searches against a collection of explicit molecules cannot be utilized, since no chemical information system could create and manage more than 10(8) explicit molecules. Nevertheless, by accepting a tolerable level of false negatives in search results, we were able to bypass the need for full 10(13) enumeration and enabled the efficient similarity search and retrieval into this huge chemical space for practical usage by medicinal chemists. In this report, two search methods (LEAP1 and LEAP2) are presented. The first method uses PGVL reaction knowledge to disassemble the incoming search query molecule into a set of reactants and then uses reactant-level similarities into actual available starting materials to focus on a much smaller sub-region of the full virtual library compound space. This sub-region is then explicitly enumerated and searched via a standard similarity method using the original query molecule. The second method uses a fuzzy mapping onto candidate reactions and does not require exact disassembly of the incoming query molecule. Instead Basis Products (or capped reactants) are mapped into the query molecule and the resultant asymmetric similarity scores are used to prioritize the corresponding reactions and reactant sets. All sets of Basis Products are inherently indexed to specific reactions and specific starting materials. This again allows focusing on a much smaller sub-region for explicit enumeration and subsequent standard product-level similarity search. A set of validation studies were conducted. The results have shown that the level of false negatives for the disassembly-based method is acceptable when the

Pursuing Qualitative Research From the Global South: "Investigative Research" During China's "Great Leap Forward" (1958-62

Directory of Open Access Journals (Sweden)

Full Text Available Over the last decade, qualitative researchers have begun to challenge the domination and universalistic claims of the Global North. Nevertheless, it is still unclear what pursuing qualitative research (QR from the Global South might entail. I advance this effort by situating it in the larger context of the decentering endeavor in social science and decolonizing methodologies in aboriginal scholarship. Informed by their locally-grounded approach in the quest for constructing alternative social science accounts and articulating decolonized knowledge, I argue that writing locally-grounded histories is an essential first step to explore methodologies and epistemologies of QR from the Global South. Noting that no national history of QR has been derived from the Global South, I present an example of writing the history of QR by examining MAO Zedong's legacy of "investigative research" (IR. Specifically, I analyze the practices of IR during China's "Great Leap Forward" (1958-62. In conclusion, I discuss the implications of IR to the development of social science research in contemporary China. I lay out key issues in pursuing QR from the Global South and present how such a pursuit is relevant to social science inquiry in the Global North.

The Thai Health Promotion Foundation supported the Improvement of Quality of Life of Informal Workers project in Ban Luang District, Amphur Photaram, Ratchaburi Province. There were many informal workers in Ban Luang District. Sweet-crispy fish producers in Ban Luang were the largest group among the sweet-crispy fish producers in Thailand. This project was aimed at improving living and working conditions of informal workers, with a focus on the sweet-crispy fish group. Good practices of improved living and working conditions were used to help informal workers build safe, healthy and productive work environments. These informal workers often worked in substandard conditions and were exposed to various hazards in the working area. These hazards included risk of exposure to hot work environment, ergonomics-related injuries, chemical hazards, electrical hazards etc. Ergonomics problems were commonly in the sweet-crispy fish group. Unnatural postures such as prolonged sitting were performed dominantly. One hundred and fifty informal workers participated in this project. Occupational health volunteers were selected to encourage occupational health and safety in four groups of informal workers in 2009. The occupational health volunteers trained in 2008 were farmers, beauty salon workers and doll makers. The occupational health and safety knowledge is extended to a new informal worker group: sweet-crispy fish producer, in 2009. The occupational health and safety training for sweet-crispy fish group is conducted by occupational health volunteers. The occupational health volunteers increased their skills and knowledge assist in to make safe home and safe community through participatory oriented training. The improvement of living and working condition is conducted by using a modified WISH, Work Improvement for Safe Home, checklist. The plans of improvement were recorded. The informal workers showed improvement mostly on material handling and storage. The safe uses and safe

Staying Safe While Doing Science in Public: Emerging Best Practices for Social Media

Science.gov (United States)

Jefferson, A.; McKinnon, M.

2016-12-01

Doing science in public has incalculable benefits for professional networking, science advocacy, and public outreach, but it also carries significant risks. Online harassment related to social media use can pose significant emotional hardship, negatively impact professional standing, and even threaten physical welfare. Women, people of color, and other underrepresented people in science are disproportionately targeted for anonymous online harassment. We analyzed our experiences with online harassment, and tactics for managing this harassment. While anecdotal, our experiences cover scientists with differing identities and fields, demonstrating that while the details change the overarching patterns remain the same. Fear of becoming a target poses a significant barrier to engaging in public discourse about science. But it is possible to mitigate this risk. Successful strategies for social media to promote science while staying safe are slowly creating a body of emerging best practices. These tactics include proactively restricting access to personal information, developing strategies for identifying and responding to deliberate antagonists (trolls), and choosing when and how to participate in volatile topics. They also require full-community engagement from creating support networks, partnering with allies to manage sudden floods of hostility, and educating on security practices for protecting colleagues' potentially sensitive personal information. It is our hope that frank and open discussion of the realistic threat passed by harassment and strategies for mitigating that threat will jump start a culture of online safety amongst geoscientists, and encourage our most vulnerable and underrepresented scientists to participate in the public sphere.

2017-07-05

The re-emergence of community-based health workers such as the auxiliary midwives (AMWs) in Myanmar, who are local female volunteers, has been an important strategy to address global health workforce shortages. The Myanmar government recommends one AMW for every village. The aim of this study is to investigate the current knowledge of critical danger signs and practices for safe childbirth and immediate newborn care of AMWs to inform potential task shifting of additional healthcare responsibilities. A cross-sectional survey was conducted from July 2015 to June 2016 in three hard-to-reach areas in Myanmar. Face-to-face interviews were conducted using a pretested questionnaire. Among 262 AMWs participating in the study, only 8% of AMWs were able to identify at least 80% of 20 critical danger signs. Factors associated with greater knowledge of critical danger signs included older age over 35 years (adjusted OR (AOR) 2.19, 95% CI 0.99 to 4.83), having received refresher training within the last year (AOR 2.20, 95% CI 1.21 to 4.01) and receiving adequate supervision (AOR 5.04, 95% CI 2.74 to 9.29). Those who employed all six safe childbirth and immediate newborn care practices were more likely to report greater knowledge of danger signs (AOR 2.81, 95% CI 1.50 to 5.26), adequate work supervision (AOR 3.18 95% CI 1.62 to 6.24) and less education (AOR 0.44, 95% CI 0.23 to 0.88). The low level of knowledge of critical danger signs and reported practices for safe childbirth identified suggest that an evaluation of the current AMW training and supervision programme needs to be revisited to ensure that existing practices, including recognition of danger signs, meet quality care standards before new interventions are introduced or new responsibilities given to AMWs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Safe operation of research reactors and critical assemblies. Code of practice and annexes. 1984 ed

International Nuclear Information System (INIS)

1984-01-01

The safe operation of research reactors and critical assemblies (hereafter termed 'reactors') requires proper design, construction, management and supervision. This Code of Practice deals mainly with management and supervision. The provisions of the Code apply to the whole life of the reactor, including modification, updating and upgrading. The Code may be subject to revision in the light of experience and the state of technology. The Code is aimed at defining minimum requirements for the safe operation of reactors. Emphasis is placed on which safety requirements should be met rather than on specifying how these requirements may be met. The Code also provides guidance and information to persons and authorities responsible for the operation of reactors. The Code recommends that documents dealing with the operation of reactors and including safety analyses be prepared and submitted for review and approval to a regulatory body. Operation would be authorized on the understanding that it would comply with limits and conditions designed to ensure safety. The Code covers a wide range of reactor types, which gives rise to a variety of safety issues. Safety issues applicable to specific reactor types only (e.g. fast reactors) are not necessarily covered in this Code. Some of the recommendations in the Code are not directly applicable to critical assemblies. A recommendation may therefore be interpreted according to the type of reactor concerned. In such cases the words 'adequate' and 'appropriate' are used to mean 'adequate' or 'appropriate' for the type of reactor under consideration.

Full Text Available Motions using Leap Motion controller are not standardized while the use of it is spreading in media contents. Each content defines its own motions, thereby creating confusion for users. Therefore, to alleviate user inconvenience, this study categorized the commonly used motion by Amusement and Functional Contents and defined the Structural Motion Grammar that can be universally used based on the classification. To this end, the Motion Lexicon was defined, which is a fundamental motion vocabulary, and an algorithm that enables real-time recognition of Structural Motion Grammar was developed. Moreover, the proposed method was verified by user evaluation and quantitative comparison tests.

Leap Motion-based virtual reality training for improving motor functional recovery of upper limbs and neural reorganization in subacute stroke patients

Virtual reality is nowadays used to facilitate motor recovery in stroke patients. Most virtual reality studies have involved chronic stroke patients; however, brain plasticity remains good in acute and subacute patients. Most virtual reality systems are only applicable to the proximal upper limbs (arms) because of the limitations of their capture systems. Nevertheless, the functional recovery of an affected hand is most difficult in the case of hemiparesis rehabilitation after a stroke. The recently developed Leap Motion controller can track the fine movements of both hands and fingers. Therefore, the present study explored the effects of a Leap Motion-based virtual reality system on subacute stroke. Twenty-six subacute stroke patients were assigned to an experimental group that received virtual reality training along with conventional occupational rehabilitation, and a control group that only received conventional rehabilitation. The Wolf motor function test (WMFT) was used to assess the motor function of the affected upper limb; functional magnetic resonance imaging was used to measure the cortical activation. After four weeks of treatment, the motor functions of the affected upper limbs were significantly improved in all the patients, with the improvement in the experimental group being significantly better than in the control group. The action performance time in the WMFT significantly decreased in the experimental group. Furthermore, the activation intensity and the laterality index of the contralateral primary sensorimotor cortex increased in both the experimental and control groups. These results confirmed that Leap Motion-based virtual reality training was a promising and feasible supplementary rehabilitation intervention, could facilitate the recovery of motor functions in subacute stroke patients. The study has been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-OCH-12002238). PMID:29239328

The Wolf motor function test (WMFT) was used to assess the motor function of the affected upper limb; functional magnetic resonance imaging was used to measure the cortical activation. After four weeks of treatment, the motor functions of the affected upper limbs were significantly improved in all the patients, with the improvement in the experimental group being significantly better than in the control group. The action performance time in the WMFT significantly decreased in the experimental group. Furthermore, the activation intensity and the laterality index of the contralateral primary sensorimotor cortex increased in both the experimental and control groups. These results confirmed that Leap Motion-based virtual reality training was a promising and feasible supplementary rehabilitation intervention, could facilitate the recovery of motor functions in subacute stroke patients. The study has been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-OCH-12002238).

Full Text Available Virtual reality is nowadays used to facilitate motor recovery in stroke patients. Most virtual reality studies have involved chronic stroke patients; however, brain plasticity remains good in acute and subacute patients. Most virtual reality systems are only applicable to the proximal upper limbs (arms because of the limitations of their capture systems. Nevertheless, the functional recovery of an affected hand is most difficult in the case of hemiparesis rehabilitation after a stroke. The recently developed Leap Motion controller can track the fine movements of both hands and fingers. Therefore, the present study explored the effects of a Leap Motion-based virtual reality system on subacute stroke. Twenty-six subacute stroke patients were assigned to an experimental group that received virtual reality training along with conventional occupational rehabilitation, and a control group that only received conventional rehabilitation. The Wolf motor function test (WMFT was used to assess the motor function of the affected upper limb; functional magnetic resonance imaging was used to measure the cortical activation.

It has been estimated that one-third of all work-related deaths occur while driving for work-related purposes. Despite this, many organisations are unaware of the practices, beyond those that identify and control the impact of unforeseen events (i.e., risk management), that predispose drivers to risk. This study addresses the issue by identifying the management practices operationalised as, High Performance Workplace Systems (HPWS) that influence safe driver behaviour. The study also explores the value given to safety by senior level management as a moderator of the relationship between HPWS practices and driver behaviour. Each factor was tested within a two level hierarchical model consisting of 911 drivers, nested within 161 supervisors and 83 organisations. The findings highight that under conditions of high investment in job and work design, communication and selection practices, drivers reported poorer driving behaviour. An interaction effect also demonstrated that under conditions of high investment in remuneration, drivers reported safer behaviour, but only when they perceived that managers valued and prioritised safety. The findings challenge current thinking in the management of workplace road safety. Copyright © 2017 Elsevier Ltd. All rights reserved.

Griko, Yuri; Regan, Matthew D.

2018-02-01

Animal research aboard the Space Shuttle and International Space Station has provided vital information on the physiological, cellular, and molecular effects of spaceflight. The relevance of this information to human spaceflight is enhanced when it is coupled with information gleaned from human-based research. As NASA and other space agencies initiate plans for human exploration missions beyond low Earth orbit (LEO), incorporating animal research into these missions is vitally important to understanding the biological impacts of deep space. However, new technologies will be required to integrate experimental animals into spacecraft design and transport them beyond LEO in a safe and practical way. In this communication, we propose the use of metabolic control technologies to reversibly depress the metabolic rates of experimental animals while in transit aboard the spacecraft. Compared to holding experimental animals in active metabolic states, the advantages of artificially inducing regulated, depressed metabolic states (called synthetic torpor) include significantly reduced mass, volume, and power requirements within the spacecraft owing to reduced life support requirements, and mitigated radiation- and microgravity-induced negative health effects on the animals owing to intrinsic physiological properties of torpor. In addition to directly benefitting animal research, synthetic torpor-inducing systems will also serve as test beds for systems that may eventually hold human crewmembers in similar metabolic states on long-duration missions. The technologies for inducing synthetic torpor, which we discuss, are at relatively early stages of development, but there is ample evidence to show that this is a viable idea and one with very real benefits to spaceflight programs. The increasingly ambitious goals of world's many spaceflight programs will be most quickly and safely achieved with the help of animal research systems transported beyond LEO; synthetic torpor may

Interventions to prevent sudden unexpected death in infancy (SUDI) have generally been population wide interventions instituted after case-control studies identified specific childcare practices associated with sudden death. While successful overall, in New Zealand (NZ), the rates are still relatively high by international comparison. This study aims to describe childcare practices related to SUDI prevention messages in a New Zealand community, and to develop and explore the utility of a risk assessment instrument based on international guidelines and evidence. Prospective longitudinal study of 209 infants recruited antenatally. Participant characteristics and infant care data were collected by questionnaire at: baseline (third trimester), and monthly from infant age 3 weeks through 23 weeks. Published meta-analyses data were used to estimate individual risk ratios for 6 important SUDI risk factors which, when combined, yielded a "SUDI risk score". Most infants were at low risk for SUDI with 72% at the lowest or slightly elevated risk (combined risk ratio ≤1.5). There was a high prevalence of the safe practices: supine sleeping (86-89% over 3-19 weeks), mother not smoking (90-92% over 3-19 weeks), and not bed sharing at a young age (87% at 3 weeks). Five independent predictors of a high SUDI risk score were: higher parity (P =0.028), younger age (P =0.030), not working or caring for other children antenatally (P =0.031), higher depression scores antenatally (P =0.036), and lower education (P =0.042). Groups within the community identified as priorities for education about safe sleep practices beyond standard care are mothers who are young, have high parity, low educational levels, and have symptoms of depression antenatally. These findings emphasize the importance of addressing maternal depression as a modifiable risk factor in pregnancy.

Katisi, Masego; Daniel, Marguerite

2015-01-01

Botswana has been running Safe Male Circumcision (SMC) since 2009 and has not yet met its target. Donors like the US Centers for Disease Control and Prevention and Africa Comprehensive HIV/AIDS Partnership (funded by the Gates Foundation) in collaboration with Botswana's Ministry of Health have invested much to encourage HIV-negative men to circumcise. Demand creation strategies make use of media and celebrities. The objective of this paper is to explore responses to SMC in relation to circumcision as part of traditional initiation practices. More specifically, we present the views of two communities in Botswana on SMC consultation processes, implementation procedures and campaign strategies. The methods used include participant observation, in-depth interviews with key stakeholders (donors, implementers and Ministry officials), community leaders and men in the community. We observe that consultation with traditional leaders was done in a seemingly superficial, non-participatory manner. While SMC implementers reported pressure to deliver numbers to the World Health Organization, traditional leaders promoted circumcision through their routine traditional initiation ceremonies at breaks of two-year intervals. There were conflicting views on public SMC demand creation campaigns in relation to the traditional secrecy of circumcision. In conclusion, initial cooperation of local chiefs and elders turned into resistance.

Cox, J.

1971-01-01

This book is in two parts. The first is a Code of Practice for the Safe Operation of Critical Assemblies and Research Reactors, prepared as a result of a meeting of experts which took place in Vienna on 20-24 May 1968. The Code has been prepared by the International Atomic Energy Agency in co-operation with the World Health Organization, and its publication is sponsored by both organizations. In addition, the Code was approved by the Board of Governors of the International Atomic Energy Agency on 16 December 1968 as part of the Agency's safety standards, which are applied to operations undertaken by Member States with the assistance of the Agency. The Board, in approving the publication of the present book, also recommended Member States to take the Code into account in the formulation of national regulations and recommendations. The second part of the book is a Technical Appendix to give information and illustrative samples that would be helpful in implementing the Code of Practice. This second part, although published under the same cover, is not part of the Code. An extensive Bibliography, amplifying the Technical Appendix, is included at the end.

As a measure to establish a climate-friendly energy system, Korean government has proposed to expand landfill gas (LFG) electricity generation capacity. The purpose of this paper is to analyze the impacts of LFG electricity generation on the energy market, the cost of generating electricity and greenhouse gases emissions in Korea using a computer-based software tool called 'Long-range Energy Alternative Planning system' (LEAP) and the associated 'Technology and Environmental Database'. In order to compare LFG electricity generation with existing other generating facilities, business as usual scenario of existing power plants was surveyed, and then alternative scenario investigations were performed using LEAP model. Different alternative scenarios were considered, namely the base case with existing electricity facilities, technological improvement of gas engine and LFG maximum utilization potential with different options of gas engine (GE), gas turbine (GT), and steam turbine (ST). In the technological improvement scenario, there will be 2.86 GWh or more increase in electricity output, decrease of 45 million won (Exchange rate (1$=1200 won)). in costs, and increase of 10.3 thousand ton of CO 2 in global warming potentials due to same period (5 year) of technological improvement. In the maximum utilization potential scenario, LFG electricity generation technology is substituted for coal steam, nuclear, and combined cycle process. Annual cost per electricity product of LFG electricity facilities (GE 58MW, GT 53.5MW, and ST 54.5MW) are 45.1, 34.3, and 24.4 won/kWh, and steam turbine process is cost-saving. LFG-utilization with other forms of energy utilization reduces global warming potential by maximum 75% with compared to spontaneous emission of CH 4 . LFG electricity generation would be the good solution for CO 2 displacement over the medium term and additional energy profits

McPherson, Madeleine; Karney, Bryan

2014-01-01

Panama recently enacted a new law, which aims to promote wind energy by mandating long term power purchase tenders. The implications of this new law lend some uncertainty to Panama's electricity development pathway. This paper quantitatively analyzes the current status of power generation in Panama, and explores various potential future scenarios and the associated impacts on the system marginal cost, global warming potential, and resource diversity index. To this end, this study applies the scenario development methodology developed by Schwartz in the context of the energy-economic modeling platform ‘Long-range Energy Alternative Planning’ (LEAP). Four scenarios are developed and analyzed. The Business as Usual scenario extrapolates the electricity generation trend that has been observed over the last decade; it is compared to three alternative scenarios which have more specific objectives. Scenario 1 encourages climate mitigation without incorporating new technologies in the generation mix, Scenario 2 maximizes resource diversity, and Scenario 3 minimizes global warming potential. For each scenario, the composition of the electricity generation profile, system marginal cost, global warming potential, and resource diversity is predicted quantitatively. These scenarios to not attempt to forecast likely developments, but rather illuminate the tradeoffs that different development pathways entail. - Highlights: • This paper models Panama's electricity sector using the LEAP model platform. • Four scenarios are developed and analyzed. • Impact analysis includes: system cost, global warming potential, resource diversity index. • Panama can achieve a sustainable grid with existing technologies and costs. • There is an tradeoff between the resource diversity and global warming potential

Highlights: • Electro-thermal performance of open-loop controlled dual axis CPVT is investigated. • For using the absorbed heat, active ventilation with a heat storage tank is used. • Economic optimization of the system is performed, using Frog Leap algorithm. • Detailed model of all sections is simulated with their characteristics evaluation. • Triple-junction photovoltaic cells, which are the most recent technology, are used. - Abstract: In this study, design and optimization of a concentrated photovoltaic thermal (CPVT) system considering electrical, mechanical, and economical aspects is investigated. For this purpose, each section of the system is simulated in MATLAB, in detail. Triple-junction photovoltaic cells, which are the most recent technology, are used in this study. They are more efficient in comparison to conventional photovoltaic cells. Unlike ordinary procedures, in this work active ventilation is used for absorbing the thermal power of radiation, using heat storage tanks, which not only results in increasing the electrical efficiency of the system through decreasing the temperature, but also leads to storing and managing produced thermal energy and increasing the total efficiency of the system up to 85 percent. The operation of the CPVT system is investigated for total hours of the year, considering the needed thermal load, meteorological conditions, and hourly radiation of Khuznin, a city in Qazvin province, Iran. Finally, the collector used for this system is optimized economically, using frog leap algorithm, which resulted in the cost of 13.4 $/m"2 for a collector with the optimal distance between tubes of 6.34 cm.

Transfer pricing and safe harbours

Directory of Open Access Journals (Sweden)

Veronika Solilová

Full Text Available Transfer prices are significant for both taxpayers and tax administrations because they determine in large part taxable profits of associated enterprises in different tax jurisdictions. Moreover, in the context of taxation, transfer prices must be complied with the arm’s length principle. However, Multinational Enterprises have been faced daily by conflicting rules and approaches to applying the arm’s length principle, burdensome documentation requirements, inconsistent audit standards and unpredictable competent authority outcomes. Therefore, the Committee on Fiscal Affairs launched another project on the administrative aspects of transfer pricing in 2010. On 16 May 2013 as a partial solution of this project was approved by the OECD Council the Revised Section E on Safe Harbours in Chapter IV of the Transfer Pricing Guidelines for Multinational Enterprises and Tax Authorities. The paper is focused on significant changes of newly approved chapter IV of the Transfer Pricing Guidelines for Multinational Enterprises and Tax Authorities, further on analysis of practice in this area, on advantages and disadvantages of safe harbours for taxpayers and competent authorities with aim to suggest recommendations on use of safe harbours in the Czech Republic.

Liu, Q. B.; Wang, Q. J.; Lei, M. F.

2015-09-01

It is known that the accuracies of medium- and long-term prediction of changes of length of day (LOD) based on the combined least-square and autoregressive (LS+AR) decrease gradually. The leap-step autoregressive (LSAR) model is more accurate and stable in medium- and long-term prediction, therefore it is used to forecast the LOD changes in this work. Then the LOD series from EOP 08 C04 provided by IERS (International Earth Rotation and Reference Systems Service) is used to compare the effectiveness of the LSAR and traditional AR methods. The predicted series resulted from the two models show that the prediction accuracy with the LSAR model is better than that from AR model in medium- and long-term prediction.

The leap from ROI to SROI: Farther than expected?

Science.gov (United States)

Gargani, John

2017-10-01

Social return on investment (SROI) is a popular method for evaluating the impact that organizations have on society and the environment. It has its roots in finance, where return on investment (ROI) is used to evaluate investments. Over the past ten years, SROI has made the leap from a tool for building private wealth to one that advances the public good. Has it landed us in a better place? To answer the question, I describe the general approach to financial analysis, how it is applied to financial decisions, and how it has been adapted to evaluate impact. I then consider the strengths and weaknesses of SROI, and suggest how, by pushing beyond the constraints of financial analysis, it can give stakeholders voice and provide evidence of success from diverse perspectives. Along the way, I propose a conceptual model for value, a foundational concept in SROI that has been criticized by some as underdeveloped, and I include a technical appendix that identifies potential sources of statistical bias in SROI estimates. I conclude by acknowledging our growing need to incorporate efficiency as one of multiple success criteria and the role that SROI-properly implemented-can play. Copyright © 2017 Elsevier Ltd.

An Analysis of the Precision and Reliability of the Leap Motion Sensor and Its Suitability for Static and Dynamic Tracking

Directory of Open Access Journals (Sweden)

2014-02-01

Full Text Available We present the results of an evaluation of the performance of the Leap Motion Controller with the aid of a professional, high-precision, fast motion tracking system. A set of static and dynamic measurements was performed with different numbers of tracking objects and configurations. For the static measurements, a plastic arm model simulating a human arm was used. A set of 37 reference locations was selected to cover the controller’s sensory space. For the dynamic measurements, a special V-shaped tool, consisting of two tracking objects maintaining a constant distance between them, was created to simulate two human fingers. In the static scenario, the standard deviation was less than 0.5 mm. The linear correlation revealed a significant increase in the standard deviation when moving away from the controller. The results of the dynamic scenario revealed the inconsistent performance of the controller, with a significant drop in accuracy for samples taken more than 250 mm above the controller’s surface. The Leap Motion Controller undoubtedly represents a revolutionary input device for gesture-based human-computer interaction; however, due to its rather limited sensory space and inconsistent sampling frequency, in its current configuration it cannot currently be used as a professional tracking system.

To establish a consensual and coherent ranking of healthcare programmes that involve the presence of ward-based and clinic-based clinical pharmacists, based on health outcome, health costs and safe delivery of care. This descriptive study was derived from a structured dialogue (Delphi technique) among directors of pharmacy department. We established a quantitative profile of healthcare programmes at five sites that involved the provision of ward-based and clinic-based pharmaceutical care. A summary table of evidence established a unique quality rating per inpatient (clinic-based) or outpatient (ward-based) healthcare programme. Each director rated the perceived impact of pharmaceutical care per inpatient or outpatient healthcare programme on three fields: health outcome, health costs and safe delivery of care. They agreed by consensus on the final ranking of healthcare programmes. A ranking was assigned for each of the 18 healthcare programmes for outpatient care and the 17 healthcare programmes for inpatient care involving the presence of pharmacists, based on health outcome, health costs and safe delivery of care. There was a good correlation between ranking based on data from a 2007-2008 Canadian report on hospital pharmacy practice and the ranking proposed by directors of pharmacy department. Given the often limited human and financial resources, managers should consider the best evidence available on a profession's impact to plan healthcare services within an organization. Data are few on ranking healthcare programmes in order to prioritize which healthcare programme would mostly benefit from the delivery of pharmaceutical care by ward-based and clinic-based pharmacists. © 2012 The Authors.

Full Text Available Instructing personnel in the issues of labor protection and industrial safety at hazardous facilities is one of the main tasks that face the employer; the quality with which this procedure is organized and carried out defines not only company’s indicators, but the mere possibility of its normal functioning. The paper contains a detailed overview of the typical content of standard documentation, which is currently used when conducting operations in the oil mines of Yarega high-viscosity oil deposit. Distinct features and unique nature of this oil field require special measures to guarantee safety of personnel and all facilities in general.The author proposes and reviews an additional type of operating guidelines – instructional map of safe working methods and practices. It is more illustrative than existing documentation (charts of inclined shaft development, labor protection regulations, which allows to upgrade the process of instructing personnel in the oil mines, to improve the quality of instructions and to reduce the risk of emergencies, accidents, industrial injuries.The author reviews the structure of suggested instructional map, offers a detailed arrangement diagram for the main thematic sections of the map, as well as their content. Instructional maps are regarded as a type of operating guidelines that include: description and characteristics of equipment, instruments and appliances; general safety requirements; content and execution sequence of operational elements with their graphical images; distribution of responsibilities with an indication of their priority in case the operations are conducted by several workers; specific safety requirements for equipment, materials, instruments, safety clothes and footwear, personal protective gear etc. (prohibitions, warnings.Advantages and disadvantages of proposed instructional maps of safe working methods and practices are highlighted.

 In evolutionary linguistics, experiments using artificial signal spaces are being used to investigate the emergenceof speech structure. These signal spaces need to be continuous, non-discretized spaces from which discrete unitsand patterns can emerge. They need to be dissimilar from-but comparable with-the vocal tract, in order tominimize interference from pre-existing linguistic knowledge, while informing us about language. This is a hardbalance to strike. This article outlines a new approach that uses the Leap Motion, an infrared controller that canconvert manual movement in 3d space into sound. The signal space using this approach is more flexible than signalspaces in previous attempts. Further, output data using this approach is simpler to arrange and analyze. Theexperimental interface was built using free, and mostly open- source libraries in Python. We provide our sourcecode for other researchers as open source.

Neural Network Analysis of LEAP Energy Spectra

Energy Technology Data Exchange (ETDEWEB)

Holdridge, Robert E

2002-09-10

The Laser Electron Acceleration Project (LEAP) group has been conducting a proof of principle experiment on the acceleration of electrons with a pair of crossed laser beams. To date there has been no experimental verification of electron acceleration with crossed laser beams in a dielectric loaded vacuum, although the energy profile of an accelerated electron bunch has been well described by theory. The experiment is subject to unavoidable time dependent fluctuations in the independent variables. Changes in the experimental parameters can dramatically alter the beam profile incident near the focal plane of a high-resolution spectrometer located downstream from the accelerator cell. Neural networks (NNs) appear to provide an ideal tool for the positive determination of an acceleration event, being adaptable and able to handle highly complex nonlinear problems. Typical NNs under such conditions require a training set consisting of a representative data set along with ''answers'' which have been determined to be consistent with the variable state of the experimental parameters. A strategy of pattern recognition with respect to the status of independent variables can be employed to determine the signature characteristics of a laser perturbed electron bunch. Data cuts representing characteristics that were thought to be distinctive to accelerated beam profile images were implemented in the algorithm employed. Statistical analysis of the results of data cuts made on the energy profile images from the experiment is presented, as well as conclusions drawn from the results of this analysis. Finally, a discussion of future directions to be taken in this work is given including the orientation towards on-line, real-time analysis.

Effects of variability of practice in music: A pilot study on fast goal-directed movements in pianists

Full Text Available Variability of Practice (VOP refers to the acquisition of a particular target movement by practicing a range of varying targets rather than by focusing on fixed repetitions of the target only. VOP has been demonstrated to have beneficial effects on transfer to a novel task and on skill consolidation. This study extends the line of research to musical practice. In a task resembling a barrier-knockdown paradigm, 36 music students trained to perform a wide left-hand interval leap on the piano. Performance at the target distance was tested before and after a 30-minute standardized training session. The high-variability group (VAR practiced 4 different intervals including the target. Another group (FIX practiced the target interval only. A third group (SPA performed spaced practice on the target only, interweaving with periods of not playing. Transfer was tested by introducing an interval novel to either group. After a 24-hour period with no further exposure to the instrument, performance was retested. All groups performed at comparable error levels before training, after training, and after the retention interval. At transfer, however, the FIX group, unlike the other groups, committed significantly more errors than in the target task. After the retention period, the effect was washed out for the FIX group but then was present for VAR. Thus, the results provide only partial support for the VOP hypothesis for the given setting. Additional exploratory observations suggest tentative benefits of VOP regarding execution speed, loudness, and performance confidence.We derive specific hypotheses and specific recommendations regarding sample selection and intervention duration for future investigations. Furthermore, the proposed leap task measurement is shown to be (a robust enough to serve as a standard framework for studies in the music domain, yet (b versatile enough to allow for a wide range of designs not previously investigated for music on a

Performance at the target distance was tested before and after a 30-min standardized training session. The high-variability group (VAR) practiced four different intervals including the target. Another group (FIX) practiced the target interval only. A third group (SPA) performed spaced practice on the target only, interweaving with periods of not playing. Transfer was tested by introducing an interval novel to either group. After a 24-h period with no further exposure to the instrument, performance was retested. All groups performed at comparable error levels before training, after training, and after the retention (RET) interval. At transfer, however, the FIX group, unlike the other groups, committed significantly more errors than in the target task. After the RET period, the effect was washed out for the FIX group but then was present for VAR. Thus, the results provide only partial support for the VOP hypothesis for the given setting. Additional exploratory observations suggest tentative benefits of VOP regarding execution speed, loudness, and performance confidence. We derive specific hypotheses and specific recommendations regarding sample selection and intervention duration for future investigations. Furthermore, the proposed leap task measurement is shown to be (a) robust enough to serve as a standard framework for studies in the music domain, yet (b) versatile enough to allow for a wide range of designs not previously investigated for music on a standardized basis.

Lead is still seen as one of the most harmful environmental toxins for young children, with the predominant source being deteriorating lead-based paint. Those at continued risk include those living in homes built before 1978, renovators and remodelers, and especially those with limited access to proper healthcare and diets. Proper training on lead-safe work practices focused on preventing and reducing the spread of lead dust can help reduce lead exposure. Presented in this paper are experiences in delivering lead-safe work practices training in six Arkansas cities, and results from pre- and post- surveys delivered before and immediately after the training. Pre- and post-surveys assess strong and weak areas of training. Participants demonstrated positive shifts in attitude and behavior towards lead-safe work practices following training. However, our research found that more emphasis should be focused on clarifying current lead exposure sources and routes for children.

The leap motion controller (LMC) is a new optoelectronic system for capturing motion of both hands and controlling a virtual environment. Differently from previous devices, it optoelectronically tracks the fine movements of fingers neither using glows nor markers. This pilot study explored the feasibility of adapting the LMC, developed for videogames, to neurorehabilitation of elderly with subacute stroke. Four elderly patients (71.50 ± 4.51 years old) affected by stroke in subacute phase were enrolled and tested in a cross-over pilot trial in which six sessions of 30 minutes of LMC videogame-based therapy were added on conventional therapy. Measurements involved participation to the sessions, evaluated by means of the Pittsburgh Rehabilitation Participation Scale, hand ability and grasp force evaluated respectively by means of the Abilhand Scale and by means of the dynamometer. Neither adverse effects nor spasticity increments were observed during LMC training. Participation to the sessions was excellent in three patients and very good in one patient during the LMC trial. In this period, patients showed a significantly higher improvement in hand abilities (P = 0.028) and grasp force (P = 0.006). This feasibility pilot study was the first one using leap motion controller for conducting a videogame-based therapy. This study provided a proof of concept that LMC can be a suitable tool even for elderly patients with subacute stroke. LMC training was in fact performed with a high level of active participation, without adverse effects, and contributed to increase the recovery of hand abilities.

Improper use of pesticides among farmers has caused food safety issues which are serious threats to public health in China. A central question concerns how to motivate farmers to self-regulate their pesticide usage. The paper aims to identify the influence of an internal driving factor, i.e., perceived benefits, and an external driving factor, i.e., subjective norm, on farmers' safe pesticide behaviors, and whether the two factors are moderated by the exposure to information on government policies and the market, based on a sample of 971 farmers selected from 5 Chinese provinces. The results revealed that farmers' safe pesticide usage was predominately driven by perceived benefits whereas external pressure or subjective norm did not play much of a role. Interaction effects were found between the exposure to market information and perceived benefits, and also between subjective norm and exposure to government policy. Extensions agencies are recommended to effectively convey to farmers the benefits to follow safe pesticide practices. Meanwhile, surveillance and monitoring systems should be established so that the prices of their agricultural products are reflected by the quality of the products.

Implicit attitudes towards risky and safe driving in a Danish sample

DEFF Research Database (Denmark)

Martinussen, Laila Marianne

; further, self-reports of the intention to drive safely (or not) are socially sensitive. Therefore, we examined automatic preferences towards safe and risky driving with a Go/No-go Association Task (GNAT). The results suggest that (1) implicit attitudes towards driving behavior can be measured reliably...... with the GNAT; (2) implicit attitudes towards safe driving versus towards risky driving may be separable constructs. We propose that research on driving behavior may benefit from routinely including measures of implicit cognition. A practical advantage is a lesser susceptibility to social desirability biases......, compared to self-report methods. Pending replication in future research, the apparent dissociation between implicit attitudes towards safe versus risky driving that we observed may contribute to a greater theoretical understanding of the causes of unsafe and risky driving behavior....

Lessons from Semmelweis:A Social Epidemiologic Update On Safe Motherhood

Directory of Open Access Journals (Sweden)

Julie Cwikel

2008-01-01

Full Text Available In this historical review, Ignaz Semmelweis's study of handwashing to prevent puerperal fever is described and used as a benchmark from which to identify salient issues that are informative to today's women’s health activists working for Safe Motherhood. The epidemiology of contemporary excess maternal mortality is reviewed. Using the conceptual framework of social epidemiology, the paper addresses four issues that were problematic in Semmelweis’ era. New tools in public health are presented that can help to solve critical, still challenging problems to reduce excess maternal mortality, nosocomial infections, and puerperal fever at childbirth: 1 progress in behavioral methods to promote health behavior change, 2 the introduction of participatory action research, 3 the diffusion of evidence-based public health practice and 4 understanding how politics and health interact and present challenges when trying to meet public health goals. Social exclusion and marginality are still key issues in determining who has access to safe motherhood and who risks her life in maternity. Applied social epidemiology allows practitioners to make effective use of the already accumulated evidence and translate it into effective public health practice to promote safe motherhood around the world.

Ates, Seyithan A.

2015-01-01

With the assistance of the LEAP (long-range energy alternatives planning) energy modeling tool, this study explores the energy efficiency and CO_2 emission reduction potential of the iron and steel industry in Turkey. With a share of 35%, the steel and iron industry is considered as the most energy-consuming sector in Turkey. The study explores that the energy intensity rate can be lowered by 13%, 38% and 51% in SEI (slow-speed energy efficiency improvement), AEI (accelerating energy efficiency improvement) and CPT (cleaner production and technology scenario) scenarios, respectively. Particularly the projected aggregated energy savings of the scenarios CPT and AES are very promising with saving rates of 33.7% and 23% respectively. Compared to baseline scenarios, energy efficiency improvements correspond to economic potential of 0.1 billion dollars for SEI, 1.25 dollars for AEI and 1.8 billion dollars for CPT scenarios annually. Concerning GHG (greenhouse gas) emissions, in 2030 the iron and steel industry in Turkey is estimated to produce 34.9 MtCO_2 in BAU (business-as-usual scenario), 32.5 MtCO_2 in SEI, 24.6 MtCO_2 in AEI and 14.5 MtCO_2 in CPT a scenario which corresponds to savings of 9%–39%. The study reveals that energy consumption and GHG emissions of the iron and steel industry can be lowered significantly if the necessary measures are implemented. It is expected that this study will fill knowledge gaps pertaining to energy efficiency potential in Turkish energy intensive industries and help stakeholders in energy intensive industries to realize the potential for energy efficiency and GHG mitigation. - Highlights: • This paper explores energy efficiency potential of iron and Steel industry in Turkey. • We applied the LEAP modeling to forecast future developments. • Four different scenarios have been developed for the LEAP modeling. • There is a huge potential for energy efficiency and mitigation of GHG emissions.

Leaping shampoo glides on a 500-nm-thick lubricating air layer

2013-11-01

When a stream of shampoo is fed onto a pool in one's hand, a jet can leap sideways or rebound from the liquid surface in an intriguing phenomenon known as the Kaye effect. Earlier studies have debated whether non-Newtonian effects are the underlying cause of this phenomenon, making the jet glide on top of a shear-thinning liquid layer, or whether an entrained air layer is responsible. Herein we show unambiguously that the jet slides on a lubricating air layer [Lee et al., Phys. Rev. E 87, 061001 (2013)]. We identify this layer by looking through the pool liquid and observing its rupture into fine micro-bubbles. The resulting micro-bubble sizes suggest that the thickness of this air layer is around 500 nm. This thickness estimate is also supported by the tangential deceleration of the jet during the rebounding, with the shear stress within the thin air layer sufficient for the observed deceleration. Particle tracking within the jet shows uniform velocity, with no pronounced shear, which would be required for shear-thinning effects. The role of the surfactant may primarily be to stabilize the air film.

The main goal of this study is to investigate the potential of the Leap Motion Controller (LMC) for the objective assessment of motor dysfunctioning in patients with Parkinson's disease (PwPD). The most relevant clinical signs in Parkinson's Disease (PD), such as slowness of movements, frequency variation, amplitude variation, and speed, were extracted from the recorded LMC data. Data were clinically quantified using the LMC software development kit (SDK). In this study, 16 PwPD subjects and 12 control healthy subjects were involved. A neurologist assessed the subjects during the task execution, assigning them a score according to the MDS/UPDRS-Section III items. Features of motor performance from both subject groups (patients and healthy controls) were extracted with dedicated algorithms. Furthermore, to find out the significance of such features from the clinical point of view, machine learning based methods were used. Overall, our findings showed the moderate potential of LMC to extract the motor performance of PwPD.

Introduction Sleep-related infant deaths are major contributors to Tennessee's high infant mortality rate. The purpose of this initiative was to evaluate the impact of policy-based efforts to improve modeling of safe sleep practices by health care providers in hospital settings across Tennessee. Methods Safe sleep policies were developed and implemented at 71 hospitals in Tennessee. Policies, at minimum, were required to address staff training on the American Academy of Pediatrics' safe sleep recommendations, correct modeling of infant safe sleep practices, and parent education. Hospital data on process measures related to training and results of crib audits were compiled for analysis. Results The overall observance of infants who were found with any risk factors for unsafe sleep decreased 45.6% (p ≤ 0.001) from the first crib audit to the last crib audit. Significant decreases were noted for specific risk factors, including infants found asleep not on their back, with a toy or object in the crib, and not sleeping in a crib. Significant improvements were observed at hospitals where printed materials or video were utilized for training staff compared to face-to-face training. Discussion Statewide implementation of the hospital policy intervention resulted in significant reductions in infants found in unsafe sleep situations. The most common risk factors for sleep-related infant deaths can be modeled in hospitals. This effort has the potential to reduce sleep-related infant deaths and ultimately infant mortality.

Importance of safety review to the safe operation of a nuclear plant

International Nuclear Information System (INIS)

Brinkerhoff, L.C.

1978-01-01

Widely differing standards of construction of nuclear reactors are employed in different countries. Although the reactor vendors, including designers and construction contractors, have a vested interest in safety, the ultimate responsibility for safety rests with the reactor facility operator. Even though governmental agencies, either directly or indirectly, must take a strong lead in developing policies and practices of safe operation, the reactor facility operator must recognize and accept the full responsibility for safe operation of the facility. The policies and practices of safe operation imposed by governmental agencies must help assure the prudent operation and the adequate maintenance of those structures, systems, and components of importance to safety. Since each country has a slightly different philosophy for achieving safety and each vendor utilizes different structures, systems, and components to fulfil this philosophy, it is imperative that the facility operator adequately maintain those engineered safety features and those plant protective systems which have been engineered into achieving the desired levels of safety. An additional method of helping to assure that those structures, systems, and components of importance to safety are prudently operated and adequately maintained is to assign the full safety responsibility for the overall operations of the reactor facility to the operating organization, i.e. assigning a 'line of responsibility' within the reactor facility operator. This assurance can be further strengthened by requiring that the facility operator establish a safety review body that overviews the operation and assures that the operating organization complies with those policies and practices of safe operation which have been imposed on the reactor facility.

Parents play a fundamental role in teaching their children safe driving skills to reduce risk of motor vehicle crashes, the leading cause of death for teens. Steering Teens Safe is a new parent-based intervention that equips parents with communication skills to talk about, demonstrate, and practice safe driving behaviors and skills with their teens. This implementation evaluation focuses on a sample of 83 parents who delivered Steering Teens Safe to their teens. One-, 2- and 3-month follow-up assessments were conducted with intervention parents to evaluate the self-reported quantity and quality of talking about, demonstrating, and practicing safe driving goals with teens; perceived success and benefit of the program; and barriers to implementation. Over 3 months of follow-up, parents discussed driving goals with their teens for a median of 101.5 minutes. The most frequently addressed topics were general safety principles, including distracted driving, driving in bad weather, wearing a seat belt, and being a safe passenger. Parents spent a median of 30 minutes practicing safe driving skills such as changing lanes. Sixty-seven percent of parents talked to their children about rural road safety, but just 36% demonstrated and half practiced these skills with their teens. Barriers to implementation include time and opportunity barriers and resistant attitudes of their teens. However, barriers neither affected frequency of engagement nor parents' perceived benefit and comfort in delivering the program. Parents with time/opportunity barriers also had higher practice and demonstration times than parents without these barriers. Findings indicate high acceptability among parent implementers and promise for real-world delivery. Future studies are needed to assess intervention impact.

Background Cultural safety has the potential to improve the health disparities between Indigenous and non-Indigenous Canadians, yet practical applications of the concept are lacking in the literature. Purpose This study aims to identify the key components of culturally safe health initiatives for the Indigenous population of Canada to refine its application in health-care settings. Methods We conducted a scoping review of the literature pertaining to culturally safe health promotion programs, initiatives, services, or care for the Indigenous population in Canada. Our initial search yielded 501 publications, but after full review of 44 publications, 30 were included in the review. After charting the data, we used thematic analysis to identify themes in the data. Results We identified six themes: collaboration/partnerships, power sharing, address the broader context of the patient's life, safe environment, organizational and individual level self-reflection, and training for health-care providers. Conclusion While it is important to recognize that the provision of culturally safe initiatives depend on the specific interaction between the health-care provider and the patient, having a common understanding of the components of cultural safety, such as those that we identified through this research, will help in the transition of cultural safety from theory into practice.

In the Learning Early About Peanut Allergy (LEAP) study, early peanut introduction in high-risk 4- to 11-month-olds was associated with a significantly decreased risk of developing peanut allergy. However, the influences of key baseline high-risk factors on peanut tolerance are poorly understood. Secondary analysis was conducted on the publically available LEAP dataset, exploring relationships between peanut tolerance, baseline peanut/egg sensitization, eczema severity/duration, age of introduction, gender, and race. A multiple logistic regression model predicting odds of successful oral food challenge (OFC) at 60 months noted higher odds with early introduction (OR 9.2, P introduction group was 83% vs 43% in the avoidance group with SPT wheal of introduction between 6 and 11 months than at 4-6 months. Increasing eczema severity had limited impact on the probability of peanut tolerance in the early introduction arm. Increasing peanut wheal size predicted peanut tolerance only in the avoidance arm. Peanut introduction between 6 and 11 months of age was associated with the highest rates of peanut tolerance, questioning the 'urgency' of introduction before 6 months. © 2016 John Wiley & Sons A/S.

According to T. de Chardin, it is the third stage in the development of the earth, after the geosphere and the biosphere. As well as the emergence of life has fundamentally changed the geosphere, the emergence of human consciousness has fundamentally changed the biosphere. De Chardin envisioned the “planetarization” of mankind, which is equivalent to the current globalization by information technology. From an anthropological point of view, internet is not a technology or media as others: it has the potential to revolutionize the current civilizational paradigm. With the advent of the internet the idea of the noosphere has been reactualized and related to the concept of collective intelligence. The article questions the hypothesis of an evolutionary leap in a greater collective intelligence or higher level of collective consciousness presenting pros and cons.

Are nursing students safe when choosing gluteal intramuscular injection locations?

Science.gov (United States)

Cornwall, J

2011-01-01

Nurses are required to perform gluteal intramuscular (IM) injections in practice. There are dangers associated with erroneous performance of this task, particularly with dorsogluteal injections. Knowledge regarding safe injection practice is therefore vital for nursing students. Fifty-eight second year students at a New Zealand Nursing School were given schematic drawings of the posterior and lateral aspects of the gluteal region. They were asked to mark and justify the safest location for gluteal IM injections. Fifty-seven students marked the dorsal schematic and one the lateral, with 38 (66.7%) marking in the upper outer quadrant (UOQ). Twenty indicating the UOQ (52.6%) wrote 'sciatic' or 'nerve' in justifying their location. Nineteen (33.3%) marked a location outside the UOQ; nine (47.4%) of these mentioned 'sciatic' or 'nerve' as reasons for injection safety. Overall, 50% of students mentioned 'sciatic' or 'nerve' in justifying the safety of their chosen injection location. Results suggest some second year nursing students do not understand safe gluteal IM injection locations and rationale. Current teaching practices and IM injection techniques could be revisited to prepare students more effectively; this may help prevent pathologies arising from this procedure.

Sleep-related infant deaths remain a major public health issue. Multiple interventions have been implemented in efforts to increase adherence to safe sleep recommendations. We conducted a systematic review of the international research literature to synthesize research on interventions to reduce the risk of sleep-related deaths and their effectiveness in changing infant sleep practices. We searched PubMed, CINAHL, PsycINFO, and Google Scholar for peer-reviewed articles published between 1990 and 2015 which described an intervention and reported results. Twenty-nine articles were included for review. Studies focused on infant caregivers, health care professionals, peers, and child care professionals. Targeted behaviors included sleep position, location, removing items from the crib, breastfeeding, smoke exposure, clothing, pacifier use, and knowledge of Sudden Infant Death Syndrome. Most articles described multi-faceted interventions, including: one-on-one or group education, printed materials, visual displays, videos, and providing resources such as cribs, pacifiers, wearable blankets, and infant t-shirts. Two described public education campaigns, one used an educative questionnaire, and one encouraged maternal note taking. Health professional interventions included implementing safe sleep policies, in-service training, printed provider materials, eliciting agreement on a Declaration of Safe Sleep Practice, and sharing adherence data. Data collection methods included self-report via surveys and observational crib audits. Over half of the studies utilized comparison groups which helped determine effectiveness. Most articles reported some degree of success in changing some of the targeted behaviors; no studies reported complete adherence to recommendations. Future studies should incorporate rigorous evaluation plans, utilize comparison groups, and collect demographic and collect follow-up data.

We evaluated images in popular stock photography websites for adherence with American Academy of Pediatrics (AAP) guidelines for safe infant sleep practices. Three top stock photo websites were used to collect photographs generated from key phrases. All images depicting an infant sleep environment were analyzed for consistency with AAP guidelines. Descriptive statistics, chi-square and z test of proportions, were conducted. A total of 1233 of 1947 stock photographs showed sleeping infants on a flat surface. In all, 627 (50.8%) photographs showed the infant in the supine position and 79 (5%) of all infant sleep environments were adherent with AAP recommendations. Bedding inconsistent with safe sleep recommendations was identified in 1133 images (71.3%), with blankets noted in 49.5%. Images depicting sleeping infants on stock photography sites do not routinely adhere to AAP recommendations. Media messages inconsistent with health care messages create confusion and misinformation about infant sleep safety and may lead inadvertently to unsafe practices.

At present, near-surface shear wave velocities are mainly calculated through Rayleigh wave dispersion-curve inversions in engineering surface investigations, but the required calculations pose a highly nonlinear global optimization problem. In order to alleviate the risk of falling into a local optimal solution, this paper introduces a new global optimization method, the shuffle frog-leaping algorithm (SFLA), into the Rayleigh wave dispersion-curve inversion process. SFLA is a swarm-intelligence-based algorithm that simulates a group of frogs searching for food. It uses a few parameters, achieves rapid convergence, and is capability of effective global searching. In order to test the reliability and calculation performance of SFLA, noise-free and noisy synthetic datasets were inverted. We conducted a comparative analysis with other established algorithms using the noise-free dataset, and then tested the ability of SFLA to cope with data noise. Finally, we inverted a real-world example to examine the applicability of SFLA. Results from both synthetic and field data demonstrated the effectiveness of SFLA in the interpretation of Rayleigh wave dispersion curves. We found that SFLA is superior to the established methods in terms of both reliability and computational efficiency, so it offers great potential to improve our ability to solve geophysical inversion problems.

Advances in virtual and augmented reality (AR) are having an impact on the medical field in areas such as surgical simulation. Improvements to surgical simulation will provide students and residents with additional training and evaluation methods. This is particularly important for procedures such as the endoscopic third ventriculostomy (ETV), which residents perform regularly. Simulators such as NeuroTouch, have been designed to aid in training associated with this procedure. The authors have designed an affordable and easily accessible ETV simulator, and compare it with the existing NeuroTouch for its usability and training effectiveness. This simulator was developed using Unity, Vuforia and the leap motion (LM) for an AR environment. The participants, 16 novices and two expert neurosurgeons, were asked to complete 40 targeting tasks. Participants used the NeuroTouch tool or a virtual hand controlled by the LM to select the position and orientation for these tasks. The length of time to complete each task was recorded and the trajectory log files were used to calculate performance. The resulting data from the novices' and experts' speed and accuracy are compared, and they discuss the objective performance of training in terms of the speed and accuracy of targeting accuracy for each system.

There is little research on HIV awareness and practices of traditional birth attendants (TBA) in India. This study investigated knowledge and attitudes among rural TBA in Karnataka as part of a project examining how traditional birth attendants could be integrated into prevention-of-mother-to-child transmission of HIV (PMTCT) programs in India. A cross-sectional survey was conducted between March 2008 and January 2009 among TBA in 144 villages in Mysore Taluk, Karnataka. Following informed consent, TBA underwent an interviewer-administered questionnaire in the local language of Kannada on practices and knowledge around birthing and HIV/PMTCT. Of the 417 TBA surveyed, the median age was 52 years and 96% were Hindus. A majority (324, 77.7%) had no formal schooling, 88 (21.1%) had up to 7 years and 5 (1%) had more than 7 yrs of education. Only 51 of the 417 TBA (12%) reported hearing about HIV/AIDS. Of those who had heard about HIV/AIDS, only 36 (72%) correctly reported that the virus could be spread from mother to child; 37 (74%) identified unprotected sex as a mode of transmission; and 26 (51%) correctly said healthy looking people could spread HIV. Just 22 (44%) knew that infected mothers could lower the risk of transmitting the virus to their infants. An overwhelming majority of TBA (401, 96.2%) did not provide antenatal care to their clients. Over half (254, 61%) said they would refer the woman to a hospital if she bled before delivery, and only 53 (13%) felt referral was necessary if excessive bleeding occurred after birth. Traditional birth attendants will continue to play an important role in maternal child health in India for the foreseeable future. This study demonstrates that a majority of TBA lack basic information about HIV/AIDS and safe delivery practices. Given the ongoing shortage of skilled birth attendance in rural areas, more studies are needed to examine whether TBA should be trained and integrated into PMTCT and maternal child health programs in

The grand leap of the whale up the Niagara Falls: converting philosophical conclusions into policy prescriptions.

Holm, Søren

2015-04-01

This article analyzes a neat conjuring trick employed in bioethics, that is, the immediate conversion of a philosophical conclusion into a policy prescription, and compares it to the "grand leap of the whale up the Niagara Falls" mentioned by Benjamin Franklin. It is shown that there is no simple and easy way to achieve the conversion, by considering arguments falling under four headings: (1) reasonable disagreement about values and theories, (2) general jurisprudential arguments, (3) the differences between policymaking and philosophy, and (4) the messy world of implementation. The particular issue used to illustrate the difficulties in moving from philosophical conclusion to policy description is infanticide of healthy infants, but the analysis is general, and the conclusion that the immediate move to policy is illegitimate is quite general.

Infusion therapy is widely used in hospitals. It is well known that medication errors constitute one of the highest risks to patient safety, leading to numerous adverse events concerning incorrect application of infusion technology. Both clinical practice and in vitro studies show that infusion of multiple medications via one access point induces unwanted phenomena such as backflow and an incorrect system response to interventions. Within the Metrology for Drug Delivery project, we addressed the role of infusion devices in drug delivery. We surveyed current practices for application in hospitals to provide input to standards and quality norms for the materials used in infusion technology. Furthermore, we organized meetings with clinicians and other relevant stakeholders to set up a risk analysis-based infusion policy, accompanied by easy to access operating procedures on infusion technology. It was found difficult to establish clear-cut infusion safety guidelines based on quantitative data because of the many different application areas and stakeholders. However, both the expert team and the survey indicated the value of multidisciplinary qualitative discussion for defining best practices. We advise to incorporate specific requirements on infusion devices in protocols and standards, adjusted to specific applications, to ensure safe use of infusion technology.

Medium- and Long-term Prediction of LOD Change by the Leap-step Autoregressive Model

Wang, Qijie

2015-08-01

The accuracy of medium- and long-term prediction of length of day (LOD) change base on combined least-square and autoregressive (LS+AR) deteriorates gradually. Leap-step autoregressive (LSAR) model can significantly reduce the edge effect of the observation sequence. Especially, LSAR model greatly improves the resolution of signals’ low-frequency components. Therefore, it can improve the efficiency of prediction. In this work, LSAR is used to forecast the LOD change. The LOD series from EOP 08 C04 provided by IERS is modeled by both the LSAR and AR models. The results of the two models are analyzed and compared. When the prediction length is between 10-30 days, the accuracy improvement is less than 10%. When the prediction length amounts to above 30 day, the accuracy improved obviously, with the maximum being around 19%. The results show that the LSAR model has higher prediction accuracy and stability in medium- and long-term prediction.

"Same Room, Safe Place".

There are many different professional stances on safe sleep and then there is the reality of caring for a newborn. There is a debate among professionals regarding safe sleep recommendations. The continum of recommendations vary from the American Academy of Pediatrics (AAP) Safe Sleep Guidelines to the bed-sharing recommendations from the Mother-Baby Behavioral Sleep Laboratory. The lack of consistent and uniform safe sleep recommendations from health professionals has been confusing for families but has more recently raised a real professional ethical dilemma. Despite years of focused safe sleep community education and interventions, sleep-related infant deaths are on the rise in many communities. This commentary calls for a united safe sleep message from all health professionals to improve health for mothers and infants most at-risk, "Same Room, Safe Place."

The ghost of Afrikaner identity in Ancestral voices, Leap year and The long silence of Mario Salviati (Etienne van Heerden

2017-04-01

Full Text Available Ghost characters are a characteristic of the novels of Etienne van Heerden, but little research has been done concerning the nature and function of these ghost characters. In this article I discuss Van Heerden’s use of ghost characters diachronically with reference to the novels Ancestral voices (1986, Leap year (1993 and The long silence of Mario Salviati (2000. In order to clarify the nature of these ghosts, I use the so-called science of the paranormal as a framework. The ghosts in the three novels will be classified accordingly, and then discussed within the context of the novels in which they appear. In this way, I shall show how the ghost characters in these novels can be read as a constantly changing embodiment of Afrikaner identity (a central theme in Van Heerden’s oeuvre. Van Heerden’s Afrikaner changes with the times: in Ancestral voices the ghost characters form a collective that represents a fragmented image of the stereotypical, archaic male Afrikaner identity; in Leap year a liminal character is written in a liminal time to embody a liminal Afrikaner identity; and in The long silence of Mario Salviati Van Heerden moves away from the exclusive Afrikaner identity to a broader South African identity by using ghost characters from very different backgrounds and origins. In conclusion I shall compare these identities and the historical contexts of these novels in order to show the function of Van Heerden’s ghost characters as constant rewritings of South African identities.

To evaluate the impact of LEAP, a volunteer-based, inpatient asthma education program for families of inner-city children with asthma. 711 children ages 2-17 years admitted with status asthmaticus were randomized to receive usual care or usual care plus a supplemental education intervention. Both groups completed a baseline interview. Trained volunteer lay educators conducted individualized bedside education with the intervention group. Primary outcome was attendance at a post-hospitalization follow-up visit 7-10 days after discharge. Secondary outcomes included parent-reported asthma management behaviors, symptoms, and self-efficacy scores from a one month follow-up interview. Post-hospitalization asthma clinic attendance was poor (38%), with no difference between groups. Families randomized to the intervention group were more likely to report use of a controller (OR 2.4, 95% CI 1.3-4.2, peducation by trained lay volunteers was associated with improved asthma management behaviors. This novel volunteer-based program could have widespread implications as a sustainable model for asthma education. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Proton pump inhibitors (PPIs) are widely prescribed drugs in daily practice. Allergic reactions, even small number of anaphylactic reactions to PPIs have been reported. Omeprazole, lansoprazole, pantoprazole, rapeprazol and esomeprazole are classified in the same group. Despite the similarity of biochemical structures among these drugs, presence of cross-reactivity between PPIs is controversial.1,2 In this letter, we present 3 lansoprazole allergy cases, who were prescribed and took esomeprazole safely after allergic reactions to lansoprazole.

The LEAP simulation model requires the values of some exogenous variables: At international level, the population increase, the economic growth and the international oil prices; at domestic level, the population increase, the economic growth, the energy intensity, the elasticity of demand of energy-price, and the elasticity of energy demand-gross national product. The use of the LEAP model for the estimation of the penetration of the renewable energies in Mexico comprises of the requirements established in the study. To estimate the future long term values of variables as the exogenous ones required by this model by means of expert opinion can be, given the nature of same, equally or more complicated and speculative than to directly consider the future rates of penetration of the renewable energies. In order to reflect on the future values of these variables a group of approach with experts was integrated. [Spanish] El modelo de simulacion LEAP requiere los valores de algunas variables exogenas: A nivel internacional, el crecimiento demografico, el crecimiento economico y los precios internacionales del petroleo; a nivel nacional, el crecimiento demografico, el crecimiento economico, la intensidad energetica, la elasticidad de demanda de energia-precio, y la elasticidad de demanda de energia-producto interno bruto. El uso del modelo LEAP para la estimacion de la penetracion de las energias renovables en Mexico forma parte de los requerimientos establecidos en el estudio. Estimar los futuros valores a largo plazo de variables como las exogenas requeridas por dicho modelo mediante opinion experta puede resultar, dada la naturaleza de las mismas, tan o mas complicado y especulativo que estimar las futuras tasas de penetracion de las energias renovables directamente. Para reflexionar sobre los futuros valores de dichas variables se integro un grupo de enfoque con expertos.

The leap into the global market is not easy when it involves a provincial family business. This article demonstrates how adequate planning is fundamental in a small and medium-sized enterprise (SME) with the tight budget they have available to them, in order to be able to differentiate themselves in a highly competitive market, taking into accounts the benefits and risks involved. The Information Technology (IT) tools put in place will give the necessary support and allow for the possibility of increasing and improving the infrastructure as the company requires. An adequate strategy for the future to increases sales would be e-marketing techniques as well as the current promotions which contribute to diffusing the brand.

Within hospital pediatric units, there is a lack of consistent application or modeling of the American Academy of Pediatrics recommendations for safe infant sleep. The purpose of this study was to improve safe sleep practices for infants in nonneonatal pediatric units with implementation of specific interventions. This multi-institutional study was conducted by using baseline observations collected for sleep location, position, and environment (collectively, "safe sleep") of infants admitted to pediatric units. Interventions consisted of: (1) staff education, including a commitment to promote safe sleep; (2) implementing site-generated safe sleep policies; (3) designating supply storage in patient rooms; and/or (4) caregiver education. Postintervention observations of safe sleep were collected. Eight hospitals participated from the Inpatient FOCUS Group of the Children's Hospital Association. Each site received institutional review board approval/exemption. Safe sleep was observed for 4.9% of 264 infants at baseline and 31.2% of 234 infants postintervention (Ppresent in 77% of cribs at baseline and 44% postintervention. However, the mean number of unsafe items observed in each sleeping environment was reduced by >50% (P=.001). Implementation of site-specific interventions seems to improve overall safe sleep in inpatient pediatric units, although continued improvement is needed. Specifically, extra items are persistently left in the sleeping environment. Moving forward, hospitals should evaluate their compliance with American Academy of Pediatrics recommendations and embrace initiatives to improve modeling of safe sleep.

When do we think it is Safe to Drive after Hand Surgery? – Current Practice and Legal Perspective

LENUS (Irish Health Repository)

Murphy, SF

2016-11-01

Patients recovering from hand surgery frequently ask when it is safe to drive and it is unclear where the responsibility lies; the surgeon, the patient or the insurance company. An eight-question survey looking at various aspects of clinical practice was circulated to consultant and trainee plastic and orthopaedic surgeons in Ireland and the UK. Of the 89 surgeons who replied, (53%) felt the decision when to drive was the patient’s compared with the insurance company (40%) and the surgeon (7%). 80% advised patients to contact their insurance company. 87% were unaware of current regulations or guidelines. National guidelines were vague and left the decision with the treating doctor. Similarly, major insurers advise patients to contact their doctor for advice. From a legal standpoint, the patient has a duty of care to other road users to be in full control of his vehicle prior to driving, regardless of any advice received.

Regulatory Framework and Current Practices of the Radioactive Material Safe and Secure Transport in Albania

2016-01-01

Attempts for the establishing of a safe and secure radioactive material transport in Albania began a decade ago with formulation of the different regulation in the field of safe and secure handling of the radioactive materials. In 2004 a special regulation for the safe transport of radioactive material was prepared and approved by the National Radiation Protection Commission). This regulation has been based in the IAEA standards for the radioactive material transport and was reviewed periodically. The last regulation of the radioactive material transport was approved by Albanian government through a governmental ordinance. The transport of the radioactive material in Albania is performed by licensed subjects, which fulfill all requirements of the mentioned governmental ordinance. Based in the existing regulation, for each transport of radioactive material, a special permission is issued by NRPC. The issuing of permission allows competent authority to provide necessary information on transport regularity and to have under survey all transports of the radioactive material carried out inside the country. Last year were issued more than 80 permissions for the transport of the different types and categories of the radioactive sources. (author)

Full Text Available The Pennsylvania Patient Safety Authority receives over 235,000 reports of medical error per year. Near miss and serious event reports of common and interesting problems are analysed to identify best practices for preventing harmful errors. Dissemination of this evidence-based information in the peer-reviewed Pennsylvania Patient Safety Advisory and presentations to medical staffs are not sufficient for adoption of best practices. Adoption of best practices has required working with institutions to identify local barriers to and incentives for adopting best practices and redesigning the delivery system to make desired behaviour easy and undesirable behaviour more difficult. Collaborations, where institutions can learn from the experiences of others, have show decreases in harmful events. The Pennsylvania Program to Prevent Wrong-Site Surgery is used as an example. Two collaborations to prevent wrong-site surgery have been completed, one with 30 institutions in eastern Pennsylvania and one with 19 in western Pennsylvania. The first collaboration achieved a 73% decrease in the rolling average of wrong-site events over 18 months. The second collaboration experienced no wrong-site operating room procedures over more than one year.

Eleven safe havens exist in Europe providing offshore banking and low taxes. Ten of these states are very small while Switzerland is moderately small. All 11 countries are richer than their large neighbors. It is shown that causality is from small to safe haven to wealth, and that theoretically...... equilibriums are likely to exist where a certain regulation is substantially lower in a small country than in its big neighbor. This generates a large capital inflow to the safe havens. The pool of funds that may reach the safe havens is shown to be huge. It is far in excess of the absorptive capacity...... of the safe havens, but it still explains, why they are rich. Microstates offer a veil of anonymity to funds passing through, and Switzerland offers safe storage of funds....

This Manual is provided as a guide to the safe operation of critical assemblies and small research reactors. It is intended that it should be used by all authorities and persons concerned with, or responsible for, the use of such equipment, in addition to the scientists and technologists who are actually working with, or operating it. It is suggested that it will be of use to those wishing to design and manufacture, or purchase, critical assemblies or research reactors, as well as those already in possession of them, and that it will prove particularly helpful to those users who have no direct access to other collected sources of information. This Manual is not a set of rules or a code of practice, but a series of recommendations which must be interpreted with scientific judgement in their application to any particular problem. The guiding principles are given from which good operational procedures may be established and improved. The promulgation of rigid standards is both impossible and undesirable at the present time, since the topics discussed form part of a rapidly growing science and technology. Therefore, any recommendations made should not be used to restrict or inhibit future developments. The Manual is intended mainly for use in those Member States where there has been little experience in the operation of critical assemblies and research reactors. It has been compounded from the best practices which exist in Member States having a large amount of such experience, so that nothing in it should conflict with the best practices to be encountered in the field of safe operation.

Consensus shaping and safe space public participation processes

Energy Technology Data Exchange (ETDEWEB)

Andersson, Kjell [Karita Research AB, Taeaby (Sweden)

2015-07-01

Stakeholder involvement and public participation is recognized as a necessary part of nuclear waste management. It is possible to see three driving forces behind this development: (1) a deliberative movement with its roots in the 1960s leftish movement (a philosophical argument), (2) the need for public acceptance of proposed solutions (a practical argument), and (3) the need for awareness and clarity before crucial decisions are made (a practical and democratic argument). Depending on which driving force dominates an initiative for public participation, the initiator is likely to prefer certain public participation processes before others. The initiator has to select among a large number of processes already having been implemented or design a new one tailored for the specific situation. The process choice is crucial for which stakeholders are able to join and which goals can be reached. Much of the debate about public participation has referred to the ''Arnstein ladder'' (Arnstein, 1969) or its modernized versions, such as the participation ladder used in the IPPA Project (Richardson et.al. 2011) building on work by the Netherlands Environmental Assessment Agency (MNP, 2008).

Consensus shaping and safe space public participation processes

Stakeholder involvement and public participation is recognized as a necessary part of nuclear waste management. It is possible to see three driving forces behind this development: (1) a deliberative movement with its roots in the 1960s leftish movement (a philosophical argument), (2) the need for public acceptance of proposed solutions (a practical argument), and (3) the need for awareness and clarity before crucial decisions are made (a practical and democratic argument). Depending on which driving force dominates an initiative for public participation, the initiator is likely to prefer certain public participation processes before others. The initiator has to select among a large number of processes already having been implemented or design a new one tailored for the specific situation. The process choice is crucial for which stakeholders are able to join and which goals can be reached. Much of the debate about public participation has referred to the ''Arnstein ladder'' (Arnstein, 1969) or its modernized versions, such as the participation ladder used in the IPPA Project (Richardson et.al. 2011) building on work by the Netherlands Environmental Assessment Agency (MNP, 2008). The various forms of ladders have in common an increasing level of ambition for participation from low to high. The higher up on the ladder, the better it is often anticipated. However, with this should follow more responsibility and accountability of all participants, which in practice is often lacking. There are also practical problems in using the ladder to map public participation processes. For example the step 'collaboration' is ambiguous as it can mean different things.

Full Text Available Can video game design be compared to more formalized practices of scientific research or speculation within game studies? And, by virtue of an intellectual leap that in itself calls for discussion, can video games be considered as an efficient vehicle for the presentation of certain kinds of knowledge, in the same way in which papers, conference presentations, and books are? What Ratto defines as critical making (2011, the practice of producing artifacts of different sorts in order to supplement and extend critical reflection, may apply to video games as well. Forms of research through design (Zimmerman, Forlizzi and Evenson, 2007, of carpentry (Bogost, 2012, and speculative design (Dunne and Raby, 2013 have been analyzed, discussed, and maybe most importantly, put into practice in different fields of cultural and scientific production. To address this gap and to map the current (and future state of self-reflexive games, we asked both researchers and designers to imagine an application of these concepts to video games. Paraphrasing Zimmerman, Forlizzi and Evenson, what does research through game design might mean? What epistemological insights can we derive from the act of designing, making and playing video games?

growing evidence that intervention has multiple components, focusing on health education practices, with the participation of the whole community. The aim of those interventions is to help students and community members to adopt healthy and safe behaviors. Schools are taking on an increasing role in health promotion, disease prevention, and injury prevention. In the context of prevention of external causes of morbidity and mortality, it is important to recognize a risky environment, places, and risk behaviors as favorable to injury and violence, as well as the concept of accident as something one can avoid. CONCLUSION: Implementation of safe schools represents a promising new direction for school-based preventive work. It is important to note that a safe school should intervene not only in its physical structure, but it should also make it as safe as possible by gathering the school community through health education, and mainly encouraging healthy behavior.

2015-11-12

Regulated differently than drugs or foods, the market for botanical dietary supplements continues to grow worldwide. The recently implemented U.S. FDA regulation that all botanical dietary supplements must be produced using good manufacturing practice is an important step toward enhancing the safety of these products, but additional safeguards could be implemented, and unlike drugs, there are currently no efficacy requirements. To ensure a safe and effective product, botanical dietary supplements should be developed in a manner analogous to pharmaceuticals that involves identification of mechanisms of action and active constituents, chemical standardization based on the active compounds, biological standardization based on pharmacological activity, preclinical evaluation of toxicity and potential for drug-botanical interactions, metabolism of active compounds, and finally, clinical studies of safety and efficacy. Completing these steps will enable the translation of botanicals from the field to safe human use as dietary supplements.

Charusiri, W.; Eua-arporn, B.; Ubonwat, J.

2008-01-01

In 2004, the total energy consumption in Thailand increased 8.8 per cent, from 47,806 to 60,260 ktoe. Long-range Energy Alternatives Planning (LEAP) is an accounting tool that simulates future energy scenarios. According to a Business As Usual (BAU) case, the overall energy demand in Thailand is estimated to increase from 61,262 to 254,200 ktoe between 2004 and 2030. Commercial energy consumption, which comprises petroleum products, natural gas, coal and its products, and electricity, increased by 9.0 per cent in Thailand in 2004, and new and renewable energy increased by 7.8 per cent. Nearly 60 per cent of the total commercial energy supply in Thailand was imported and increased for a fifth year in a row. The changes in energy consumption can be attributed to population growth and increase in economic activity and development. 10 refs., 5 tabs., 14 figs

This Federal Code revises an earlier Code on the same subject issued in 1982 and was formulated under the Environment Protection (Nuclear Codes) Act 1978. The purpose of the Code is to establish uniform safety standards, applicable throughout the Commonwealth of Australia, to provide for the protection of persons and the environment, against any dangers associated with the transport of radioactive substances. The Code uses as a basis the IAEA Regulations for the Safe Transport of Radioactive Materials. This new edition takes into account the 1985 Edition of the Regulations incorporating the 1988 Supplement and provides, furthermore, that radiation protection standards will also be subject to recommendations of the Australian National Health and Medical Research Council [fr

Jespen, Torben

2016-01-01

This book describes the prerequisites for the placing on the market and the safe use of machinery in compliance with the relevant EU Directives, especially the Machinery Directive 2006/42. It provides readers with high-level knowledge concerning the Essential Health and Safety Requirements (EHSR) that machinery must fulfill. The approach and principles of the Machinery Directive were most recently made worldwide acknowledged in the ILO code of practice on safe machinery, released in 2013. The book addresses that code, as well as providing valuable insight into other EU Product and Workplace legislation. Focusing on the key aspect of safe machinery, the “machinery safety risk assessment”, which allows readers to better understand the more difficult aspects of risk assessments, the book equips readers to tackle problems at the manufacturing stage and in different use scenarios, introducing them to risk reduction techniques and functional safety aspects.

To describe the experiences and opinions of pharmacists serving as site coordinators for the Medication Safety Research Network of Indiana (Rx-SafeNet). Retail chain, independent, and hospital/health system outpatient community pharmacies throughout Indiana, with a total of 127 pharmacy members represented by 26 site coordinators. Rx-SafeNet, a statewide practice-based research network (PBRN) formed in 2010 and administered by the Purdue University College of Pharmacy. Barriers and facilitators to participation in available research studies, confidence participating in research, and satisfaction with overall network communication. 22 of 26 site coordinators participated, resulting in an 85% response rate. Most (72.2%) of the respondents had received a doctor of pharmacy degree, and 13.6% had postgraduate year (PGY)1 residency training. The highest reported benefits of PBRN membership were an enhanced relationship with the Purdue University College of Pharmacy (81% agreed or strongly agreed) and enhanced professional development (80% agreed or strongly agreed). Time constraints were identified as the greatest potential barrier to network participation, reported by 62% of respondents. In addition, the majority (59%) of survey respondents identified no prior research experience. Last, respondents' confidence in performing research appeared to increase substantially after becoming network members, with 43% reporting a lack of confidence in engaging in research before joining the network compared with 90% reporting confidence after joining the network. In general, Rx-SafeNet site coordinators appeared to experience increased confidence in research engagement after joining the network. While respondents identified a number of benefits associated with network participation, concerns about potential time constraints remained a key barrier to participation. These findings will assist network leadership in identifying opportunities to positively increase member participation

Ramos, Silvina; Romero, Mariana; Ortiz, Zulma; Brizuela, Vanessa

2015-12-01

In 2010, the Safe and Family-Centered Maternity Hospitals initiative was launched in order to transform large public maternity centers into settings where safe practices are implemented and the rights of women, newborn infants and families are warranted. As a result, the paradigm of perinatal care was modified. This article reports on the findings of organizational culture as a component for the implementation of the initiative. The sample was selected in a non-probabilistic way and was made up of 29 public hospitals located in the province of Buenos Aires that participated in the initiative. During 2011 and 2012, an anonymous, self-administered survey was completed by members of the Department of Neonatology and the Department of Obstetrics. The survey collected information on three dimensions of the organizational culture: organizational environment, safe practices, and facilitation of change. A total of 1828 surveys were collected; 51% of survey respondents stated that there is a need to improve communication by having more meetings, while 60% made a positive assessment of various aspects of leadership. Work overload was described as the main cause of conflicts by 60%. Approximately 25% agreed and showed commitment with the initiative of transforming maternity centers. Adherence to practices was dissimilar depending on the practice, but half of survey respondents reported that there were genuine reasons for change. The assessment of the organizational culture showed that commitment to the Safe and Family-Centered Maternity Hospitals initiative is yet to be consolidated, and the evaluation of leadership is not comprehensive. Work overload and communication failures are the main reasons for conflict.

Accident history, risk perception and traffic safe behaviour.

Ngueutsa, Robert; Kouabenan, Dongo Rémi

2017-09-01

This study clarifies the associations between accident history, perception of the riskiness of road travel and traffic safety behaviours by taking into account the number and severity of accidents experienced. A sample of 525 road users in Cameroon answered a questionnaire comprising items on perception of risk, safe behaviour and personal accident history. Participants who reported involvement in more than three accidents or involvement in a severe accident perceived road travel as less risky and also reported behaving less safely compared with those involved in fewer, or less severe accidents. The results have practical implications for the prevention of traffic accidents. Practitioner Summary: The associations between accident history, perceived risk of road travel and safe behaviour were investigated using self-report questionnaire data. Participants involved in more than three accidents, or in severe accidents, perceived road travel as less risky and also reported more unsafe behaviour compared with those involved in fewer, or less severe accidents. Campaigns targeting people with a less serious, less extensive accident history should aim to increase awareness of hazards and the potential severity of their consequences, as well as emphasising how easy it is to take the recommended preventive actions. Campaigns targeting those involved in more frequent accidents, and survivors of serious accidents, should address feelings of invulnerability and helplessness.

Safe working hours--doctors in training a best practice issue.

Science.gov (United States)

Lewis, Andrew

2002-01-01

In 1995, the Australian Medical Association launched its Safe Working Hours campaign. By 1998, this had been developed into a National Code of Conduct that continues to resonate in the Australian public health system. However, and particularly in respect of Doctors in Training (DITs) who continue to work long hours, there are levels of resistance to proposals that seek to re-organise work or change prevailing professional and cultural expectations. Long working hours have substantial impacts on a DIT's capacity to consistently deliver high quality patient care, dilute the effectiveness of their training regime and have negative consequences on their health, social life and family responsibilities. While public hospitals often maintain the view that minimal budget flexibility restricts their capacity to affect change in a positive way, in fact devisable productivity and efficiency gains can be achieved by reducing working hours. Further, the medical profession needs to consider whether long hours provide an optimal environment for quality learning and performance.

We conducted a series of focus groups to explore the information needs of clinicians and consumers related to arthritis and driving. An open coding analysis identified common themes across both consumer and clinician-based focus groups that underscored the importance of addressing driving-related concerns and the challenges associated with assessing safety. The results revealed that although driving is critical for maintaining independence and community mobility, drivers with arthritis experience several problems that can affect safe operation of a motor vehicle. Findings from this study are part of a broader research initiative that will inform the development of the Arthritis and Driving toolkit. This toolkit outlines strategies to support safe mobility for people with arthritis and will be an important resource in the coming years given the aging population.

Barriers and Facilitators to Safe Food Handling among Consumers: A Systematic Review and Thematic Synthesis of Qualitative Research Studies.

Full Text Available Foodborne illness has a substantial health and economic burden on society, and most cases are believed to be due to unsafe food handling practices at home. Several qualitative research studies have been conducted to investigate consumers' perspectives, opinions, and experiences with safe food handling at home, and these studies provide insights into the underlying barriers and facilitators affecting their safe food handling behaviours. We conducted a systematic review of previously published qualitative studies in this area to synthesize the main across-study themes and to develop recommendations for future consumer interventions and research. The review was conducted using the following steps: comprehensive search strategy; relevance screening of abstracts; relevance confirmation of articles; study quality assessment; thematic synthesis of the results; and quality-of-evidence assessment. A total of 39 relevant articles reporting on 37 unique qualitative studies were identified. Twenty-one barriers and 10 facilitators to safe food handling were identified, grouped across six descriptive themes: confidence and perceived risk; knowledge-behaviour gap; habits and heuristics; practical and lifestyle constraints; food preferences; and societal and social influences. Our overall confidence that each barrier and facilitator represents the phenomenon of interest was rated as high (n = 11, moderate (11, and low (9. Overarching analytical themes included: 1 safe food handling behaviours occur as part of a complex interaction of everyday consumer practices and habituation; 2 most consumers are not concerned about food safety and are generally not motivated to change their behaviours based on new knowledge about food safety risks; and 3 consumers are amenable to changing their safe food handling habits through relevant social pressures. Key implications and recommendations for research, policy and practice are discussed.

2015-02-01

Full Text Available Current social and political realties have focused attention on human trafficking in the United States. Although new mechanisms for criminalizing offenders and protecting victims are increasingly funded and implemented across the country, empirical exploration into the efficacy of these interventions is lacking. This article uses yearly count data on juvenile prostitution arrests aggregated at the state level to explore the criminalization of commercial sexually exploited children post safe harbor policy implementation. Preliminary data from four states suggests that the passage of safe harbor laws may not reduce the number of juveniles arrested for prostitution crimes. Implications for future research are discussed.

To investigate the effect of the Intrafix(®) SafeSet infusion apparatus on the incidence of phlebitis in patients being intravenously infused in a neurological intensive care unit (ICU). Patients aged > 12 years, with no history of diabetes mellitus and no existing phlebitis, requiring a daily peripheral intravenous infusion of ≥ 8 h with the total period lasting ≥ 3 days, were enrolled. Infusions were performed using the Intrafix(®) SafeSet or normal infusion apparatus. Incidence of phlebitis (scored according to the Infusion Nursing Standards of Practice of the American Infusion Nurses Society) was analysed. Patients (n = 1545) were allocated to Intrafix(®) SafeSet (n = 709) or normal infusion (n = 836) groups, matched for age, gender and preliminary diagnosis. Incidence of phlebitis was significantly higher using normal infusion apparatus compared with the Intrafix(®) SafeSet (23.4% versus 17.9%, respectively). Intrafix(®) SafeSet infusion apparatus significantly reduced the incidence of phlebitis in patients in the neurological ICU, compared with normal infusion apparatus, and may be suitable for use in routine clinical practice.

Exploring direct 3D interaction for full horizontal parallax light field displays using leap motion controller.

2015-04-14

This paper reports on the design and evaluation of direct 3D gesture interaction with a full horizontal parallax light field display. A light field display defines a visual scene using directional light beams emitted from multiple light sources as if they are emitted from scene points. Each scene point is rendered individually resulting in more realistic and accurate 3D visualization compared to other 3D displaying technologies. We propose an interaction setup combining the visualization of objects within the Field Of View (FOV) of a light field display and their selection through freehand gesture tracked by the Leap Motion Controller. The accuracy and usefulness of the proposed interaction setup was also evaluated in a user study with test subjects. The results of the study revealed high user preference for free hand interaction with light field display as well as relatively low cognitive demand of this technique. Further, our results also revealed some limitations and adjustments of the proposed setup to be addressed in future work.

The biggest users of GRID technologies came from the science and technology communities. These consist of government, industry and academia (national and international). The NASA GRID is moving into a higher technology readiness level (TRL) today; and as a joint effort among these leaders within government, academia, and industry, the NASA GRID plans to extend availability to enable scientists and engineers across these geographical boundaries collaborate to solve important problems facing the world in the 21 st century. In order to enable NASA programs and missions to use IPG resources for program and mission design, the IPG capabilities needs to be accessible from inside the NASA center networks. However, because different NASA centers maintain different security domains, the GRID penetration across different firewalls is a concern for center security people. This is the reason why some IPG resources are been separated from the NASA center network. Also, because of the center network security and ITAR concerns, the NASA IPG resource owner may not have full control over who can access remotely from outside the NASA center. In order to obtain organizational approval for secured remote access, the IPG infrastructure needs to be adapted to work with the NASA business process. Improvements need to be made before the IPG can be used for NASA program and mission development. The Secured Advanced Federated Environment (SAFE) technology is designed to provide federated security across NASA center and NASA partner's security domains. Instead of one giant center firewall which can be difficult to modify for different GRID applications, the SAFE "micro security domain" provide large number of professionally managed "micro firewalls" that can allow NASA centers to accept remote IPG access without the worry of damaging other center resources. The SAFE policy-driven capability-based federated security mechanism can enable joint organizational and resource owner approved remote

Bindon, Susan L

2017-08-01

Maintaining competence is a professional responsibility for nurses. Individual nurses are accountable for their practice, as outlined in the American Nurses Association's Nursing: Scope and Standards of Practice. Nurses across clinical settings face the sometimes daunting challenge of staying abreast of regulatory mandates, practice changes, equipment updates, and other workplace expectations. In the complex, evolving perioperative setting, professional development is a priority, and the need for ongoing education is critical. However, nurses' efforts to engage in their own development can be hampered by a lack of time, limited access to educational resources, or cost concerns. This article provides an overview of nursing professional development and offers some resources to help individual nurses maintain or enhance their knowledge, skills, and attitudes.

Tikunov, Vladimir S.; Tikunova, Iryna N.; Eremchenko, Eugene N.

2018-05-01

Sustainable development is one of the most important challenges for humanity and one of the priorities of the United Nations. Achieving sustainability of the whole World is a main goal of management at all levels - from personal to local to global. Therefore, decision making should be supported by relevant geospatial information system. Nevertheless, classical geospatial products, maps and GIS, violate fundamental demand of `situational awareness' concept, well-known philosophy of decision-making - same representation of situation within a same volume of time and space for all decision-makers. Basic mapping principles like generalization and projections split the universal single model of situation on number of different separate and inconsistent replicas. It leads to wrong understanding of situation and, after all - to incorrect decisions. In another words, quality of the sustainable development depends on effective decision-making support based on universal global scale-independent and projection-independent model. This new way for interacting with geospatial information is a quantum leap in cartography method. It is implemented in the so-called `Digital Earth' paradigm and geospatial services like Google Earth. Com-paring of both methods, as well as possibilities of implementation of Digital Earth in the sustain-able development activities, are discussed.

Patient involvement in safe delivery planning is considered important yet not widely practiced. The present study aimed at identifythe factors that affect patient involvementin safe delivery, as recommended by parturient women. This study was part of a qualitative research conducted by content analysis method and purposive sampling in 2013.The data were collected through 63 semi-structured interviews in4 hospitalsand analyzed using thematic content analysis. The participants in this research were women before discharge and after delivery. Findings were analyzed using Colaizzi's method. Four categories of factors that could affect patient involvement in safe delivery emerged from our analysis: patient-related (true and false beliefs, literacy, privacy, respect for patient), illness-related (pain, type of delivery, patient safety incidents), health care professional-relatedand task-related factors (behavior, monitoring &training), health care setting-related (financial aspects, facilities). More research is needed to explore the factors affecting the participation of mothers. It is therefore, recommended to: 1) take notice of mother education, their husbands, midwives and specialists; 2) provide pregnant women with insurance coverage from the outset of pregnancy, especially during prenatal period; 3) form a labor pain committee consisting of midwives, obstetricians, and anesthesiologists in order to identify the preferred painless labor methods based on the existing facilities and conditions, 4) carry out research on observing patients' privacy and dignity; 5) pay more attention on the factors affecting cesarean.

Science.gov (United States)

Lee, Corinne; Knight, Suzanne W; Smith, Sharon L; Nagle, Dorothy J; DeVries, Lori

This article addresses the development, implementation, and evaluation of an education program for safe patient handling and mobility at a large academic medical center. The ultimate goal of the program was to increase safety during patient mobility/transfer and reduce nursing staff injury from lifting/pulling. This comprehensive program was designed on the basis of the principles of prework, application, and support at the point of care. A combination of online learning, demonstration, skill evaluation, and coaching at the point of care was used to achieve the goal. Specific roles and responsibilities were developed to facilitate implementation. It took 17 master trainers, 88 certified trainers, 176 unit-based trainers, and 98 coaches to put 3706 nurses and nursing assistants through the program. Evaluations indicated both an increase in knowledge about safe patient handling and an increased ability to safely mobilize patients. The challenge now is sustainability of safe patient-handling practices and the growth and development of trainers and coaches.

 The paper draws attention to: i) key considerations involving the confidentiality, privacy, and security of shared data; and ii) the requirements needed to build collaborative arrangements encompassing all stakeholders with the goal of ensuring safe, secure, and quality use of shared data.  A narrative review of existing research and policy approaches along with expert perspectives drawn from the International Medical Informatics Association (IMIA) Working Group on Technology Assessment and Quality Development in Health Care and the European Federation for Medical Informatics (EFMI) Working Group for Assessment of Health Information Systems.  The technological ability to merge, link, re-use, and exchange data has outpaced the establishment of policies, procedures, and processes to monitor the ethics and legality of shared use of data. Questions remain about how to guarantee the security of shared data, and how to establish and maintain public trust across large-scale shared data enterprises. This paper identifies the importance of data governance frameworks (incorporating engagement with all stakeholders) to underpin the management of the ethics and legality of shared data use. The paper also provides some key considerations for the establishment of national approaches and measures to monitor compliance with best practice. Data sharing endeavours can help to underpin new collaborative models of health care which provide shared information, engagement, and accountability amongst all stakeholders. We believe that commitment to rigorous evaluation and stakeholder engagement will be critical to delivering health data benefits and the establishment of collaborative models of health care into the future.

Safe and environmentally sound management of radioactive wastes in India

International Nuclear Information System (INIS)

Krishnamoorthy, T.M.; Mishra, U.C.

1999-09-01

It was recognised quite early in India's nuclear power programme that the safe management of radioactive waste is vital for its success. An entirely self-sustained fuel cycle based on indigenous resources necessitated evaluation of hazard potential vis-a-vis radioactive wastes generated at different stages of the cycle, starting from mining and milling; fuel fabrication and through the stages of reactor operation and finally spent fuel reprocessing. Emphasis was laid on studies related to impact of radioactivity in the environment and on developing technologies to effectively isolate and contain them. The radiological safety assessment for a radioactive waste management practice is a regulatory mandate and it requires quantitative estimate of the maximum burden to the present and future generation. Safety assessment models are employed to derive this estimate that could be compared with regulatory criteria to ensure the safety of the public. Decades of experience have proved that the present practices are safe, yet there is a constant endeavour to use new technologies to further restrict the releases so that ultimate goal of radioactive waste management should go beyond merely satisfying prevailing regulations. The comprehensive system of waste management, from water generation to its disposal developed in India, is briefly presented in this report. (author)

2014-04-01

To explore nurses' experiences with and perspectives on preventing medication administration errors. Insight into nurses' experiences with and perspectives on preventing medication administration errors is important and can be utilised to tailor and implement safety practices. A qualitative interview study of 20 nurses in an academic medical centre was conducted between March and December of 2011. Three themes emerged from this study: (1) nurses' roles and responsibilities in medication safety: aside from safe preparation and administration, the clinical reasoning of nurses is essential for medication safety; (2) nurses' ability to work safely: knowledge of risks and nurses' work circumstances influence their ability to work safely; and (3) nurses' acceptance of safety practices: advantages, feasibility and appropriateness are important incentives for acceptance of a safety practice. Nurses' experiences coincide with the assumption that they are in a pre-eminent position to enable safe medication management; however, their ability to adequately perform this role depends on sufficient knowledge to assess the risks of medication administration and on the circumstances in which they work. Safe medication management requires a learning climate and professional practice environment that enables further development of professional nursing skills and knowledge. © 2014 John Wiley & Sons Ltd.

Quality assurance for the safe transport of radioactive material

International Nuclear Information System (INIS)

1994-01-01

All activities related to the safe transport of radioactive material should be covered by a quality assurance programme. This publication recognizes that a single transport operation often involves several different organizations, each having specific responsibilities. Hence, it is unlikely that the operation will be covered by a single quality assurance programme. Each quality assurance programme should be tailored to the specific organizational structure for which the programme is prepared, with account taken of the particular transport activities of that organization and the interfaces with other organizations. The aim of this publication is to give a detailed interpretation of what must be done by whom to produce a quality assurance programme for radioactive material transport. This publication provides guidance on methods and practical examples to develop QA programmes for the safe transport of radioactive material. It provides information on how to develop the programme, the standards and the common features of a QA programme

Practical Reason, Another Approach of Safe Action

International Nuclear Information System (INIS)

Blazsin, H.; Guarnieri, F.; Martin, C.

2016-01-01

Born from the realisation that technology is neither the only source of risk, nor the exclusive solution, the concept of safety culture aimed at reintegrating human action, skills and symbolic productions (representations, beliefs, values, cognitive abilities, etc.) in the preservation of safety. As such it constituted a turning point for risk management and safety studies. Yet, the concept seems to raise more and more questions, both as a concept and as a practical tool (Simard, 2000; Fuchs, 2012; Edwards et al., 2013; Lopez de Castro et al., 2013). Mostly, these questions revolve around the lack of consensus over one shared definition of safety culture; around the idea that a number of its traditionally accepted characteristics, such as its systemic nature, remain to be demonstrated; finally, and maybe most importantly, that its implementation through such management tools as questionnaires, indicators, dashboards, has deprived safety culture of its substance and diverted from its original purpose, i.e., putting humanity back at the heart of safety (Guldenmund, 2007; Karsh, Waterson, Holden, 2013; Reiman, Rollenhagen, 2013). Indeed such tools lead to classify and quantify reality in an attempt at reproducibility, leaving aside the many aspects of human action that do not fit the associated categories as well as its complexity.

Despite efforts to translate knowledge into clinical practice, barriers often arise in adapting the strict protocols of a randomized, controlled trial (RCT) to the individual patient. The Locomotor Experience Applied Post-Stroke (LEAPS) RCT demonstrated equal effectiveness of 2 intervention protocols for walking recovery poststroke; both protocols were more effective than usual care physical therapy. The purpose of this article was to provide knowledge-translation tools to facilitate implementation of the LEAPS RCT protocols into clinical practice. Participants from 2 of the trial's intervention arms: (1) early Locomotor Training Program (LTP) and (2) Home Exercise Program (HEP) were chosen for case presentation. The two cases illustrate how the protocols are used in synergy with individual patient presentations and clinical expertise. Decision algorithms and guidelines for progression represent the interface between implementation of an RCT standardized intervention protocol and clinical decision-making. In each case, the participant presents with a distinct clinical challenge that the therapist addresses by integrating the participant's unique presentation with the therapist's expertise while maintaining fidelity to the LEAPS protocol. Both participants progressed through an increasingly challenging intervention despite their own unique presentation. Decision algorithms and exercise progression for the LTP and HEP protocols facilitate translation of the RCT protocol to the real world of clinical practice. The two case examples to facilitate translation of the LEAPS RCT into clinical practice by enhancing understanding of the protocols, their progression, and their application to individual participants.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A147).

Exploring Direct 3D Interaction for Full Horizontal Parallax Light Field Displays Using Leap Motion Controller

Directory of Open Access Journals (Sweden)

Vamsi Kiran Adhikarla

2015-04-01

Full Text Available This paper reports on the design and evaluation of direct 3D gesture interaction with a full horizontal parallax light field display. A light field display defines a visual scene using directional light beams emitted from multiple light sources as if they are emitted from scene points. Each scene point is rendered individually resulting in more realistic and accurate 3D visualization compared to other 3D displaying technologies. We propose an interaction setup combining the visualization of objects within the Field Of View (FOV of a light field display and their selection through freehand gesture tracked by the Leap Motion Controller. The accuracy and usefulness of the proposed interaction setup was also evaluated in a user study with test subjects. The results of the study revealed high user preference for free hand interaction with light field display as well as relatively low cognitive demand of this technique. Further, our results also revealed some limitations and adjustments of the proposed setup to be addressed in future work.

Smart aircraft fastener evaluation (SAFE) system: a condition-based corrosion detection system for aging aircraft

Science.gov (United States)

Schoess, Jeffrey N.; Seifert, Greg; Paul, Clare A.

1996-05-01

The smart aircraft fastener evaluation (SAFE) system is an advanced structural health monitoring effort to detect and characterize corrosion in hidden and inaccessible locations of aircraft structures. Hidden corrosion is the number one logistics problem for the U.S. Air Force, with an estimated maintenance cost of $700M per year in 1990 dollars. The SAFE system incorporates a solid-state electrochemical microsensor and smart sensor electronics in the body of a Hi-Lok aircraft fastener to process and autonomously report corrosion status to aircraft maintenance personnel. The long-term payoff for using SAFE technology will be in predictive maintenance for aging aircraft and rotorcraft systems, fugitive emissions applications such as control valves, chemical pipeline vessels, and industrial boilers. Predictive maintenance capability, service, and repair will replace the current practice of scheduled maintenance to substantially reduce operational costs. A summary of the SAFE concept, laboratory test results, and future field test plans is presented.

2014-09-01

Full Text Available Indirana chiravasi, a new species of leaping frog is described from the northern Western Ghats around Amboli, Sindhudurg District, Maharashtra, India. It differs from all its congeners based on a combination of characters including presence of median single internal vocal sac, head longer than wide, distinct canthus rostralis, tympanum 2/3rd to 3/4th the diameter of eye, vomerine teeth in two oblique series at the posterior border of choanae, long midventral lingual papilla, first finger longer than or equal to second, presence of double outer palmer tubercle, thin and elongated inner metatarsal tubercle, absence of outer metatarsal tubercle, webbing moderate, dorsal skin with glandular folds but without warts, ventral skin smooth without mottling and palms and soles dark brown. Molecular analysis based on mitochondrial 12S and 16S genes and nuclear rhodopsin and rag1 genes suggests that the species is genetically distinct from other species for which genetic data is available. Preliminary observations on the development of the species are also provided. We also provide genetic data and images for Indirana gundia collected from the type locality.

2016-06-14

The Leap Motion Controller (LMC) is a low-cost, markerless motion capture device that tracks hand, wrist and forearm position. Integration of this technology into healthcare applications has begun to occur rapidly, making validation of the LMC׳s data output an important research goal. Here, we perform a detailed evaluation of the kinematic data output from the LMC, and validate this output against gold-standard, markered motion capture technology. We instructed subjects to perform three clinically-relevant wrist (flexion/extension, radial/ulnar deviation) and forearm (pronation/supination) movements. The movements were simultaneously tracked using both the LMC and a marker-based motion capture system from Motion Analysis Corporation (MAC). Adjusting for known inconsistencies in the LMC sampling frequency, we compared simultaneously acquired LMC and MAC data by performing Pearson׳s correlation (r) and root mean square error (RMSE). Wrist flexion/extension and radial/ulnar deviation showed good overall agreement (r=0.95; RMSE=11.6°, and r=0.92; RMSE=12.4°, respectively) with the MAC system. However, when tracking forearm pronation/supination, there were serious inconsistencies in reported joint angles (r=0.79; RMSE=38.4°). Hand posture significantly influenced the quality of wrist deviation (P<0.005) and forearm supination/pronation (P<0.001), but not wrist flexion/extension (P=0.29). We conclude that the LMC is capable of providing data that are clinically meaningful for wrist flexion/extension, and perhaps wrist deviation. It cannot yet return clinically meaningful data for measuring forearm pronation/supination. Future studies should continue to validate the LMC as updated versions of their software are developed.

Do nurses provide a safe sleep environment for infants in the hospital setting? An integrative review.

Science.gov (United States)

Patton, Carla; Stiltner, Denise; Wright, Kelly Barnhardt; Kautz, Donald D

2015-02-01

Sudden infant death syndrome (SIDS) may be the most preventable cause of death for infants 0 to 6 months of age. The American Academy of Pediatrics (AAP) first published safe sleep recommendations for parents and healthcare professionals in 1992. In 1994, new guidelines were published and they became known as the "Back to Sleep" campaign. After this, a noticeable decline occurred in infant deaths from SIDS. However, this number seems to have plateaued with no continuing significant improvements in infant deaths. The objective of this review was to determine whether nurses provide a safe sleep environment for infants in the hospital setting. Research studies that dealt with nursing behaviors and nursing knowledge in the hospital setting were included in the review. A search was conducted of Google Scholar, CINAHL, PubMed, and Cochrane, using the key words "NICU," "newborn," "SIDS," "safe sleep environment," "nurse," "education," "supine sleep," "prone sleep," "safe sleep," "special care nursery," "hospital policy for safe sleep," "research," "premature," "knowledge," "practice," "health care professionals," and "parents." The review included research reports on nursing knowledge and behaviors as well as parental knowledge obtained through education and role modeling of nursing staff. Only research studies were included to ensure that our analysis was based on rigorous research-based findings. Several international studies were included because they mirrored findings noted in the United States. All studies were published between 1999 and 2012. Healthcare professionals and parents were included in the studies. They were primarily self-report surveys, designed to determine what nurses, other healthcare professionals, and parents knew or had been taught about SIDS. Integrative review. Thirteen of the 16 studies included in the review found that some nurses and some mothers continued to use nonsupine positioning. Four of the 16 studies discussed nursing knowledge and

SAFE/SNAP application to shipboard security

International Nuclear Information System (INIS)

Grady, L.M.; Walker, J.L.; Polito, J.

1981-11-01

An application of the combined Safeguards Automated Facility Evaluation/Safeguards Network Analysis Procedure (SAFE/SNAP) modeling technique to a physical protection system (PPS) aboard a generic ship is described. This application was performed as an example of how the SAFE and SNAP techniques could be used. Estimates of probability of interruption and neutralization for the example shipboard PPS are provided by SAFE as well as an adversary scenario, which serves as input to SNAP. This adversary scenario is analyzed by SNAP through four cases which incorporate increasingly detailed security force tactics. Comparisons between the results of the SAFE and SNAP analyses are made and conclusions drawn on the validity of each technique. Feedback from SNAP to SAFE is described, and recommendations for upgrading the ship based on the results of the SAFE/SNAP application are also discussed

Organising a safe space for navigating social-ecological transformations to sustainability.

Science.gov (United States)

Pereira, Laura; Karpouzoglou, Timothy; Doshi, Samir; Frantzeskaki, Niki

2015-05-28

The need for developing socially just living conditions for the world's growing population whilst keeping human societies within a 'safe operating space' has become a modern imperative. This requires transformative changes in the dominant social norms, behaviours, governance and management regimes that guide human responses in areas such as urban ecology, public health, resource security (e.g., food, water, energy access), economic development and biodiversity conservation. However, such systemic transformations necessitate experimentation in public arenas of exchange and a deepening of processes that can widen multi-stakeholder learning. We argue that there is an emergent potential in bridging the sustainability transitions and resilience approaches to create new scientific capacity that can support large-scale social-ecological transformations (SETs) to sustainability globally, not just in the West. In this article, we elucidate a set of guiding principles for the design of a 'safe space' to encourage stronger interactions between these research areas and others that are relevant to the challenges faced. We envisage new opportunities for transdisciplinary collaboration that will develop an adaptive and evolving community of practice. In particular, we emphasise the great opportunity for engaging with the role of emerging economies in facilitating safe space experimentation.

WNA position statement on safe management of nuclear waste and used nuclear fuel

International Nuclear Information System (INIS)

Saint-Pierre, S.

2006-01-01

This World nuclear association (W.N.A.) Position Statement summarizes the worldwide nuclear industry's record, progress and plans in safely managing nuclear waste and used nuclear fuel. The global industry's safe waste management practices cover the entire nuclear fuel-cycle, from the mining of uranium to the long-term disposal of end products from nuclear power reactors. The Statement's aim is to provide, in clear and accurate terms, the nuclear industry's 'story' on a crucially important subject often clouded by misinformation. Inevitably, each country and each company employs a management strategy appropriate to a specific national and technical context. This Position Statement reflects a confident industry consensus that a common dedication to sound practices throughout the nuclear industry worldwide is continuing to enhance an already robust global record of safe management of nuclear waste and used nuclear fuel. This text focuses solely on modern civil programmes of nuclear-electricity generation. It does not deal with the substantial quantities of waste from military or early civil nuclear programmes. These wastes fall into the category of 'legacy activities' and are generally accepted as a responsibility of national governments. The clean-up of wastes resulting from 'legacy activities' should not be confused with the limited volume of end products that are routinely produced and safely managed by today's nuclear energy industry. On the significant subject of 'Decommissioning of Nuclear Facilities', which is integral to modern civil nuclear power programmes, the W.N.A. will offer a separate Position Statement covering the industry's safe management of nuclear waste in this context. The safe management of nuclear waste and used nuclear fuel is a widespread, well-demonstrated reality. This strong safety record reflects a high degree of nuclear industry expertise and of industry responsibility toward the well-being of current and future generations

Safe delivery care practices in western Nepal: Does women's autonomy influence the utilization of skilled care at birth?

Science.gov (United States)

Bhandari, Tulsi Ram; Kutty, V Raman; Sarma, P Sankara; Dangal, Ganesh

2017-01-01

Despite various efforts to increase the utilization of skilled birth attendants (SBA), nearly two-thirds of deliveries take place at home without the assistance of SBAs in Nepal. We hypothesized that the ability of women to take decisions about their own lives-women's autonomy-plays an important part in birth choices. To know this, we conducted a community-based cross-sectional study for assessing women's autonomy and utilization of safe delivery care service in Kapilvastu district of Nepal from June to October 2014. We used multivariate modeling to associate socioeconomic factors and women's autonomy with the utilization of safe delivery care services. Just over one-third of women sought institutional delivery care during the birth of their last child. Out of the total deliveries at health facilities, nearly 58% women visited health facility for self-reported emergency obstructive care. Only 6.2% home deliveries were handled by health workers and 14.7% women used the safe delivery kit for home delivery care. Higher levels of women's education had a strong positive association (odds ratio = 24.11, CI = 9.43-61.64) with institutional delivery care. Stratified analysis showed that when the husband is educated, women's education seems to work partly through their autonomy in decision making. Educational status of women emerged as one of the key predictors of the utilization of delivery care services in Kapilvastu district. Economic status of household and husband's education are other dominant predictors of the utilization of safe delivery care services. Improving the economic and educational status may be the way out for improving the proportion of institutional deliveries. Women's autonomy may be an important mediating factor in this pathway.

Safety Case for Safe-store

International Nuclear Information System (INIS)

Woollam, Paul B.

2002-01-01

Magnox Electric plc (Magnox), a wholly owned subsidiary of BNFL, owns 26 gas-cooled, graphite-moderated units on 11 sites in the UK. Eight units have been permanently shutdown and the remainder will shut this decade in a currently declared closure programme. The first of these reactors went to power in 1952 and the fleet has generated typically 9% of the UK's electricity during the last five decades. In accordance with UK Government policy, BNFL aims for a systematic and progressive reduction in hazards on its decommissioning sites. The end-point of the decommissioning process is that the reactors will be dismantled and their sites de-licensed. This will be done through minimising both the risks to the public, workers and the environment and also the lifetime cost, consistent with world class safety. There will be passive safe storage during deferment periods and it is BNFL's clear intent that the reactors will not be Safe-stored indefinitely. The main hazard associated with any decommissioned nuclear site is the spent fuel. Hence the reactors will be de-fuelled as soon as practicable after shutdown. After this work is complete, Cs-137 contaminated plant (e.g. fuel pools, effluent plant, and drains) will be dismantled when it is no longer needed. All other plant and buildings will also be dismantled when they are no longer needed, except for the reactor buildings which will be put into passive safe storage. Co-60 contaminated plant, such as steam generators, will be dismantled with the reactors. The reactors will be dismantled in a sequenced programme, with a notional start time around 100 years from shutdown. Magnox Electric is ensuring that the reactors and primary circuits on all its sites are well characterised. We have carried out a detailed, peer reviewed hazard identification on the lead site from which we have generated a rolling 25-year basic safety case. We have then searched for cliff edge effects and possible long-term changes to generate the 100-year

Safeness of radiological machinery

International Nuclear Information System (INIS)

Yokoyama, Shun

1979-01-01

The human factors affecting the safeness of radiological machinery, which are often very big and complicated machines, are described from the stand point of handling. 20 to 50% of the troubles on equipments seem to be caused by men. This percentage will become even higher in highly developed equipments. Human factors have a great influence on the safeness of radiological equipments. As the human factors, there are sensory factors and knowledge factors as well as psychological factors, and the combination of these factors causes mishandling and danger. Medical services at present are divided in various areas, and consist of the teamwork of the people in various professions. Good human relationship, education and control are highly required to secure the safeness. (Kobatake, H.)

Inherently safe characteristics of nuclear reactors

International Nuclear Information System (INIS)

1989-01-01

This report is based on a detailed study which was carried out by Colenco (a company of the Motor-Columbus Group) on behalf of the Commission of the European Communities (CEC). It presents a summary of this study and concentrates more on the generic issues involved in the subject of inherent safety in nuclear power plants. It is assumed that the reader is reasonably familiar with the design outline of the systems included in the report. The report examines the role of inherent design features in achieving the safety of nuclear power plants as an alternative to the practice, which is largely followed in current reactors, of achieving safety by the addition of engineered safety features. The report examines current reactor systems to identify the extent to which their characteristics are either already inherently safe or, on the other hand, have inherent characteristics that require protective action to be taken. It then considers the advantages of introducing design changes to improve their inherent safety characteristics. Next, it looks at some new reactor types for which claims of inherent safety are made to see to what extent these claims are justified. The general question is then considered whether adoption of the inherently safe reactors would give advantages (by reducing risk in real terms or by improving the public acceptability of nuclear power) which are sufficient to offset the expected high costs and the technical risks associated with any new technology

Full Text Available Socio-demographic predictors about safe sex behaviours in individual suffering from immune deficiency virus (HIV had been tried to understand in this cross-sectional study. It was conducted on 120 individuals having immune deficiency virus (HIV. Collection of the data were based on socio-demographic and a safe sex behaviour questionnaire. To determine the socio-demographic the general linear model was used. Result revealed mean (SD of the total score of safe sexual behaviour among men and women was 66.5 (13.1, 62.2 (13.0 respectively and (Score limit: 0-100. Status of sexual partners, unprotected vaginal sex, drugs and alcohols, as well as employment status, were considered as predictors of safe sex behaviours. About 50 percent of the participants pose unsafe sexual practices, thus, it is advisable that the health promotion programs and HIV prevention should implement in various groups of the society.

Working safely with electronics racks

CERN Document Server

Simon Baird, HSE Unit Head

2016-01-01

Think of CERN and you’ll probably think of particle accelerators and detectors. These are the tools of the trade in particle physics, but behind them are the racks of electronics that include power supplies, control systems and data acquisition networks.   Inside an electronics rack: danger could be lurking if the rack is not powered off. In routine operation, these are no more harmful than the home entertainment system in your living room. But unscrew the cover and it’s a different matter. Even after following appropriate training, and with formal authorisation from your group leader or equivalent to carry out electrical work or any work in the vicinity of electrical hazards, and even with extensive experience of carrying out such operations, it’s important to incorporate safe working practices into your routine. At CERN, before the racks of electronics reach their operational configurations for the accelerators and detectors, they play a vital role in test set-ups ...

Due to the high prevalence of prescription opioid misuse, the US Food and Drug Administration (FDA) mandated a Risk Evaluation and Mitigation Strategy (REMS) requiring manufacturers of extended-release/long-acting (ER/LA) opioids to fund continuing education based on an FDA curricular Blueprint. This paper describes the Safe and Competent Opioid Prescribing Education (SCOPE of Pain) train-the-trainer program and its impact on (1) disseminating the SCOPE of Pain curriculum and (2) knowledge, confidence, attitudes, and performance of the participants of trainer-led compared with expert-led meetings. SCOPE of Pain is a 3-hour ER/LA opioid REMS education. In addition to expert-led live statewide meetings, a 2-hour train-the-trainer (TTT) workshop was developed to increase dissemination nationally. The trainers were expected to conduct SCOPE of Pain meetings at their institutions. Participants of both the trainer-led and expert-led SCOPE of Pain programs were surveyed immediately post and 2 months post meetings to assess improvements in knowledge, confidence, attitudes, and self-reported safe opioid prescribing practices. During 9 months (May 2013 to February 2014), 89 trainers were trained during 9 TTT workshops in 9 states. Over 24 months (May 2013 to April 2015), 33% of the trainers conducted at least 1 SCOPE of Pain training, with a total of 79 meetings that educated 1419 participants. The average number of meetings of those who conducted at least 1 meeting was 2.8 (range: 1-19). The participants of the trainer-led programs were significantly more likely to be practicing in rural settings than those who participated in the expert-led meetings (39% vs. 26%, P strategy to increase guideline-based safe opioid prescribing knowledge, confidence, attitudes, and self-reported practices.

Aware, motivated and striving for a 'safe tan': an exploratory mixed-method study of sun-protection during holidays.

2017-01-01

Background: This article presents an exploratory study, aiming to explore the correspondence between knowledge, motivation and sun-protection practices during holidays. Methods: Seventeen participants aged 21-62 years old, recruited from community settings took part in individual face-to-face semi-structured interviews, completed sun sensitivity questions and an objective assessment of sunscreen use. Holidaymakers' knowledge about sun-safe messages, intentions and perceptions of barriers and facilitators for sun-protection were assessed. Qualitative data were analysed using thematic analysis and integrated with quantitative data, using a pragmatic theory-informed approach to synthesise the findings. Results: Participants were well informed about sun-safe messages, highly motivated to protect themselves from solar UV radiation (UVR) and they perceived themselves as well protected. However, they did not seem to use effective protective practices. Sunscreen was the preferred method of sun-protection, but most participants used considerably less than the recommended amount and significantly overestimated the amount of time they could be safely exposed. Seeking shade was the least used method of sun-protection and covering-up strategies were mostly implemented as a partial protection (i.e. hats or sunglasses). The desire to reach an optimal balance between getting a tan and using sun-protection to avoid sunburns was preeminent. Several additional barriers and facilitators for sun-protection were identified. Conclusions: Holidaymakers might have a false sense of security when it comes to sun-exposure. They are aware of the need to protect from solar UVR, but the motive for a safe tan, the overreliance on sunscreen, the overestimation of the safe sun-exposure time for their skin type and the insufficient application of sunscreen leaves holidaymakers motivated to protect their skin at significant risk of overexposure, sunburn and skin cancer. Public health messages need to

Nation launches first safe sex campaign with foreign help. Russia, education (health).

Science.gov (United States)

1997-06-30

This news brief discusses the first campaign to stop the spread of AIDS in Russia. The government is investing in newspaper advertising in order to prevent the spread of AIDS, because the alternative health care model is too expensive. The country is unable to afford the expensive drugs for treating AIDS and HIV infections, and the health care system, in general, is in decline. The health ministry is relying on the support from Medecins sans Frontieres (Doctors without Borders) to mount a newspaper campaign to urge condom use and other safe sex practices. The campaign will also involve television and radio advertisements, followed by billboards on subway stops and city buses. Since the communist break-up, IV drug use and prostitution have become widespread problems. Borders were opened, and drugs entered the country. Under the former Soviet regime, contact with foreigners was discouraged and travel was restricted. The public was exposed to AIDS information in the campaigns conducted in 1990. The public is generally informed about AIDS. The new campaign focuses on safe sex, which is a new concept for Russians. There is a wide gap between knowledge and adoption of safe sex practices. Official records indicate about 4400 HIV cases, of which 259 are in advanced stages of AIDS. Official figures are considered underestimates. Over 75% of current HIV cases involve IV drug users, but the potential for heterosexual transmission is great. About 50% of the HIV cases were recorded in Kaliningrad, a port city with a growing population of IV drug users. The city provides easy access to the rest of Europe and exposure to HIV/AIDS that is not yet found in most other Russian cities.

CO 2 emission from fossil fuels is a major cause for the global warming effect, but it is hard to remove completely in actuality. Moreover, energy consumption is bound to increase for the continuous economic development of a country that has an industrial formation requiring high-energy demand. Therefore, we need to consider not only a device for CO 2 mitigation but also its impact when a CO 2 mitigation device is applied. The device for CO 2 emission mitigation can be classified into three fields: energy consumption reduction, development of CO 2 removal and recovery technology, and development of alternative energy technology. Among these options, CO 2 removal and recovery technology has a merit that can be applied to a process in the near future. Therefore, research for CO 2 removal and recovery is actively progressing in Korea. In this study, environmental and economic assessment according to the energy policy change for climate change agreement and increase of CO 2 mitigation technology is accomplished, on the bases of operating data for the CO 2 chemical absorption pilot plant that is installed in the Seoul coal steam power plant. The Long-range Energy Alternatives Planning system (LEAP) was used to analyze the alternative scenario, and results were shown quantitatively

Endoscopic resection of large colorectal polyps is well established. However, significant differences in technique exist between eastern and western interventional endoscopists. We report the results of endoscopic resection of large complex colorectal lesions from a specialist unit that combines eastern and western techniques for assessment and resection. Endoscopic resections of colorectal lesions of at least 2 cm were included. Lesions were assessed using magnification chromoendoscopy supplemented by colonoscopic ultrasound in selected cases. A lesion-specific approach to resection with endoscopic mucosal resection or endoscopic submucosal dissection (ESD) was used. Surveillance endoscopy was performed at 3 (SC1) and 12 (SC2) months. Four hundred and sixty-six large (≥20 mm) colorectal lesions (mean size 54.8 mm) were resected. Three hundread and fifty-six were resected using endoscopic mucosal resection and 110 by ESD or hybrid ESD. Fifty-one percent of lesions had been subjected to previous failed attempts at resection or heavy manipulation (≥6 biopsies). Nevertheless, endoscopic resection was deemed successful after an initial attempt in 98%. Recurrence occurred in 15% and could be treated with endoscopic resection in most. Only two patients required surgery for perforation. Nine patients had postprocedure bleeding; only two required endoscopic clips. Ninety-six percent of patients without invasive cancer were free from recurrence and had avoided surgery at last follow-up. Combining eastern and western practices for assessment and resection results in safe and effective organ-conserving treatment of complex colorectal lesions. Accurate assessment before and after resection using magnification chromoendoscopy and a lesion-specific approach to resection, incorporating ESD where appropriate, are important factors in achieving these results.

InaSAFE applications in disaster preparedness

Pranantyo, Ignatius Ryan; Fadmastuti, Mahardika; Chandra, Fredy

2015-04-01

Disaster preparedness activities aim to reduce the impact of disasters by being better prepared to respond when a disaster occurs. In order to better anticipate requirements during a disaster, contingency planning activities can be undertaken prior to a disaster based on a realistic disaster scenario. InaSAFE is a tool that can inform this process. InaSAFE is a free and open source software that estimates the impact to people and infrastructure from potential hazard scenarios. By using InaSAFE, disaster managers can develop scenarios of disaster impacts (people and infrastructures affected) to inform their contingency plan and emergency response operation plan. While InaSAFE provides the software framework exposure data and hazard data are needed as inputs to run this software. Then InaSAFE can be used to forecast the impact of the hazard scenario to the exposure data. InaSAFE outputs include estimates of the number of people, buildings and roads are affected, list of minimum needs (rice and clean water), and response checklist. InaSAFE is developed by Indonesia's National Disaster Management Agency (BNPB) and the Australian Government, through the Australia-Indonesia Facility for Disaster Reduction (AIFDR), in partnership with the World Bank - Global Facility for Disaster Reduction and Recovery (GFDRR). This software has been used in many parts of Indonesia, including Padang, Maumere, Jakarta, and Slamet Mountain for emergency response and contingency planning.

Full Text Available The need for developing socially just living conditions for the world’s growing population whilst keeping human societies within a ‘safe operating space’ has become a modern imperative. This requires transformative changes in the dominant social norms, behaviours, governance and management regimes that guide human responses in areas such as urban ecology, public health, resource security (e.g., food, water, energy access, economic development and biodiversity conservation. However, such systemic transformations necessitate experimentation in public arenas of exchange and a deepening of processes that can widen multi-stakeholder learning. We argue that there is an emergent potential in bridging the sustainability transitions and resilience approaches to create new scientific capacity that can support large-scale social-ecological transformations (SETs to sustainability globally, not just in the West.

Heads or tails: do stranded fish (mosquitofish, Gambusia affinis know where they are on a slope and how to return to the water?

Directory of Open Access Journals (Sweden)

Robert J Boumis

Full Text Available Aquatic vertebrates that emerge onto land to spawn, feed, or evade aquatic predators must return to the water to avoid dehydration or asphyxiation. How do such aquatic organisms determine their location on land? Do particular behaviors facilitate a safe return to the aquatic realm? In this study, we asked: will fully-aquatic mosquitofish (Gambusia affinis stranded on a slope modulate locomotor behavior according to body position to facilitate movement back into the water? To address this question, mosquitofish (n = 53 were placed in four positions relative to an artificial slope (30° inclination and their responses to stranding were recorded, categorized, and quantified. We found that mosquitofish may remain immobile for up to three minutes after being stranded and then initiate either a "roll" or a "leap". During a roll, mass is destabilized to trigger a downslope tumble; during a leap, the fish jumps up, above the substrate. When mosquitofish are oriented with the long axis of the body at 90° to the slope, they almost always (97% initiate a roll. A roll is an energetically inexpensive way to move back into the water from a cross-slope body orientation because potential energy is converted back into kinetic energy. When placed with their heads toward the apex of the slope, most mosquitofish (>50% produce a tail-flip jump to leap into ballistic flight. Because a tail-flip generates a caudually-oriented flight trajectory, this locomotor movement will effectively propel a fish downhill when the head is oriented up-slope. However, because the mass of the body is elevated against gravity, leaps require more mechanical work than rolls. We suggest that mosquitofish use the otolith-vestibular system to sense body position and generate a behavior that is "matched" to their orientation on a slope, thereby increasing the probability of a safe return to the water, relative to the energy expended.

Full Text Available Background: In India, the Home Based Postnatal Newborn Care programme by Accredited Social Health Activists (ASHAs under the National Rural Health Mission was initiated in 2011 to reduce neonatal mortality rates (NMRs. ASHAs get cash incentives for six postnatal home visits for newborn care. We studied newborn care practices among mothers in Mewat, Haryana, having a high NMR and determined risk factors for unsafe practices and described the knowledge and skills of ASHAs during home visits. Methods: A cross-sectional survey was conducted among mothers who had delivered a child during the previous seven months using cluster sampling. We interviewed mothers and ASHAs in the selected subcentres using semi–structured questionnaires on the six safe newborn care practices, namely safe breastfeeding, keeping cord and eyes clean, wrapping baby, kangaroo care, delayed bathing and hand washing. Results: We interviewed 320 mothers, 61 ASHAs and observed 19 home visits. Overall, 60% of mothers adopted less than three safe practices. Wrapping newborns (96% and delayed bathing (64% were better adopted than cord care (49%, safe breastfeeding (48%, hand washing (30%, kangaroo care (20% and eye care (9%. Cultural beliefs and traditional birth attendants influenced the mother’s practices. The lack of supervision by auxiliary nurse midwives (ANM, delayed referral and transportation were the other challenges. Conclusion: Knowledge–practice gaps existed among mothers counselled by ASHAs. Poor utilization of reproductive and child health services decreased opportunities for ASHA–mother dialogue on safe practices. Recommendations included training ANMs, training TBAs as ASHAs, innovative communication strategies for ASHAs and improved referral system.

Promoting Safe Injection Practices : The Challenge Ahead

Full Text Available Injections are one of the most common health care procedures in the world. Global estimates range between 12 billion-16 billion injections each year’. Most of the injections (90 to 95% are given for therapeutic purposes and only 5 to 10% are given for immunization. It is estimated that worldwide every year a billion injections are given to women and children for immunization. Up to half of these injections are currently thought to be unsafe. Due to the sheer burden of injections and the coresponding magnitude of unsafe injections, the proportion of blood borne pathogen transmission is much larger than is due to unsafe blood transfusion. Unsafe injections are responsible for million cases of Hepatitis B and C and an estimated one-quarter of a million cases of HIV annually. Worldwide 8 to 16 million hepatitis B, 2.3 - 4.7 million hepatitis C and 80,000 - 1,60,000 HIV infections are estimated to occur yearly form reuse of syringes and needles without adequate sterilization2. In the less developed countries, the unsafe injection practices account for an estimated $ 535 million in health care costs and result in nearly 1.3 million deaths a year. In a developing country like India where unnecessary injections are common, the total bur­den of injections is estimated to be 3.7 billion injections per year3. Certain studies that have been carried out in India,along with anecdotal evidence point towards a large numbe- of unnecessary, inappropriate, unsafe injections and inadequate sharps waste management4 5. A high proportion of injections given in India for immunization are unsafe due to reuse of needles/ syringes. The popularity of curative injections remains high due to various factors influencing the behaviour of prescribers / injection givers as well as clients.

Overview of the international legal framework governing the safe and peaceful uses of nuclear energy - Some practical steps

International Nuclear Information System (INIS)

Rautenbach, J.; Tonhauser, W.; Wetherall, A.

2006-01-01

The accident on 26 April 1986 in unit 4 of the Chernobyl nuclear power plant in the former Ukrainian Republic of the Union of Soviet Socialist Republics, near the present borders of Belarus, the Russian Federation and Ukraine, was categorised at the time as 'the most devastating accident in the history of nuclear power'. Two decades on, the assessment of the health, environmental and socio-economic impacts of the accident still continues, with the aim of providing definitive and authoritative answers. In addition, from a legal perspective the accident underlined some significant deficiencies and gaps in the international legal and regulatory norms that had been established to govern the safe and peaceful uses of nuclear energy. At the same time, it stressed the need for a collective international focus on [nuclear] safety and, in its wake, prompted a call for the creation of an international regime for the safe development of [nuclear energy] under the auspices of the IAEA. For all its devastating consequences, the accident was in fact a wake-up call for the 'international nuclear community' and led to a new era in international nuclear cooperation, involving states which had so far been removed both geographically and technologically from nuclear power. In its aftermath, the international nuclear community, in an attempt to allay concerns of the public and political world over the use of the atom as a viable energy source, sought to rebuild confidence in the safety of nuclear energy, primarily through the IAEA, by urgently addressing those main deficiencies in the existing international legal framework that had been exemplified by the accident. As much as has already been written on the substantive provisions and negotiating history of the different international instruments that compromise this legal framework and that were developed under the auspices of the IAEA in the two decades since the Chernobyl accident, this paper only briefly describes their substance

Safe Handling of Radioisotopes

International Nuclear Information System (INIS)

1958-01-01

Under its Statute the International Atomic Energy Agency is empowered to provide for the application of standards of safety for protection against radiation to its own operations and to operations making use of assistance provided by it or with which it is otherwise directly associated. To this end authorities receiving such assistance are required to observe relevant health and safety measures prescribed by the Agency. As a first step, it has been considered an urgent task to provide users of radioisotopes with a manual of practice for the safe handling of these substances. Such a manual is presented here and represents the first of a series of manuals and codes to be issued by the Agency. It has been prepared after careful consideration of existing national and international codes of radiation safety, by a group of international experts and in consultation with other international bodies. At the same time it is recommended that the manual be taken into account as a basic reference document by Member States of the Agency in the preparation of national health and safety documents covering the use of radioisotopes.

Safe affordable fission engine (SAFE 30) module conductivity test thermal model correlation

International Nuclear Information System (INIS)

Roman, Jose

2001-01-01

The SAFE 30 is a simple, robust space fission power system that is comprised of several independent modules. Each module contains 4 fuel tubes bonded to a central heatpipe. Fission energy is conducted from the fuel tubes to the heatpipe, which in turn transfers the energy to a power conversion system. This paper benchmarks a thermal model of the SAFE 30 with actual test data from simulated SAFE 30 module tests. Two 'dummy' SAFE 30 modules were fabricated - each consisted of 4 1-inch dia. tubes (simulating the fuel tubes) bonded to a central '1' dia. tube (simulating the heatpipe). In the first module the fuel tubes were simply brazed to the heatpipe along the line of contact (leaving void space in the interstices), and in the second module the tubes and heatpipe were brazed via tri-cusps that completely fill the interstices between the tubes. In these tests, fission energy is simulated by placing resistance heaters within each of the 4 fuel tubes. The tests were conducted in a vacuum chamber in 4 configurations: tri-cusps filled with and without an outer insulation wrap, and no tri-cusps with and without an outer insulation wrap. The baseline SAFE 30 configuration uses the brazed tri-cusps. During the tests, the power applied to the heaters was varied in a stepwise fashion, until a steady-state temperature profile was reached. These temperature levels varied between 773 K and 1073 K. To benchmark the thermal model, the input energy and chamber surface temperature were used as boundary conditions for the model. The analytical results from the nodes at the same location as the test thermocouples were plotted again test data to determinate the accuracy of the analysis. The unknown variables on the analysis are the radiation emissivity of the pipe and chamber and the radiation view factor between the module and the chamber. A correlation was determined using a parametric analysis by varying the surface emissivity and view factor until a good match was reached. This

Crashes are the leading cause of death for teens, and parent-based interventions are a promising approach. We assess the effectiveness of Steering Teens Safe, a parent-focused program to increase safe teen driving. Steering Teens Safe aimed to improve parental communication with teens about safe driving using motivational interviewing techniques in conjunction with 19 safe driving lessons. A randomized controlled trial involved 145 parent-teen dyads (70 intervention and 75 control). Intervention parents received a 45-minute session to learn the program with four follow-up phone sessions, a DVD, and a workbook. Control parents received a standard brochure about safe driving. Scores were developed to measure teen-reported quantity and quality of parental communication about safe driving. The main outcome measure was a previously validated Risky Driving Score reported by teens. Because the Score was highly skewed, a generalized linear model based on a gamma distribution was used for analysis. Intervention teens ranked their parent's success in talking about driving safety higher than control teens (p = 0.035) and reported that their parents talked about more topics (non-significant difference). The Risky Driving Score was 21% lower in intervention compared to control teens (85% CI = 0.60, 1.00). Interaction between communication quantity and the intervention was examined. Intervention teens who reported more successful communication had a 42% lower Risky Driving Score (95% CI = 0.37, 0.94) than control parents with less successful communication. This program had a positive although not strong effect, and it may hold the most promise in partnership with other programs, such as Driver's Education or Graduated Driver's License policies.

The successful and safe transfer of the patient from one phase of care to another is contingent on optimal communication by all team members. Nurses are often in a natural leadership position to improve safe practices during hand overs. A holistic understanding of the patient allows the perioperative nurse the opportunity to identify issues and choose a nursing diagnosis based on key elements of a patient's needs and goals--information that should be relayed during patient transfers. This article reviews best practices in transfer-of-care communication to enable perioperative RNs to take an active, leading role in hand-over processes. Copyright © 2015 AORN, Inc.

ABSTRACT Background: This article presents an exploratory study, aiming to explore the correspondence between knowledge, motivation and sun-protection practices during holidays. Methods: Seventeen participants aged 21–62 years old, recruited from community settings took part in individual face-to-face semi-structured interviews, completed sun sensitivity questions and an objective assessment of sunscreen use. Holidaymakers’ knowledge about sun-safe messages, intentions and perceptions of barriers and facilitators for sun-protection were assessed. Qualitative data were analysed using thematic analysis and integrated with quantitative data, using a pragmatic theory-informed approach to synthesise the findings. Results: Participants were well informed about sun-safe messages, highly motivated to protect themselves from solar UV radiation (UVR) and they perceived themselves as well protected. However, they did not seem to use effective protective practices. Sunscreen was the preferred method of sun-protection, but most participants used considerably less than the recommended amount and significantly overestimated the amount of time they could be safely exposed. Seeking shade was the least used method of sun-protection and covering-up strategies were mostly implemented as a partial protection (i.e. hats or sunglasses). The desire to reach an optimal balance between getting a tan and using sun-protection to avoid sunburns was preeminent. Several additional barriers and facilitators for sun-protection were identified. Conclusions: Holidaymakers might have a false sense of security when it comes to sun-exposure. They are aware of the need to protect from solar UVR, but the motive for a safe tan, the overreliance on sunscreen, the overestimation of the safe sun-exposure time for their skin type and the insufficient application of sunscreen leaves holidaymakers motivated to protect their skin at significant risk of overexposure, sunburn and skin cancer.

Criteria for the safe storage of enriched uranium at the Y-12 Plant

International Nuclear Information System (INIS)

Cox, S.O.

1995-07-01

Uranium storage practices at US Department of Energy (DOE) facilities have evolved over a period spanning five decades of programmatic work in support of the nuclear deterrent mission. During this period, the Y-12 Plant in Oak Ridge, Tennessee has served as the principal enriched uranium facility for fabrication, chemical processing, metallurgical processing and storage. Recent curtailment of new nuclear weapons production and stockpile reduction has created significant amounts of enriched uranium available as a strategic resource which must be properly and safely stored. This standard specifies criteria associated with the safe storage of enriched uranium at the Y-12 Plant. Because programmatic needs, compliance regulations and desirable materials of construction change with time, it is recommended that these standards be reviewed and amended periodically to ensure that they continue to serve their intended purpose

To experimentally intervene safe injection by medical staff in basic-level hospitals and observe the recent and long-term effect after the intervention and to provide practical measures to improve safe injection. We used random sampling methods to set up groups in county hospitals and township hospitals of Hunan Province, and offered lectures, delivered safe injection guide, brochure and on-site guidance in the experimental group. We surveyed the 2 groups after the intervention at 1 month and 6 months to compare the effect of unsafe injection behaviors and safe injection behaviors. One month after the intervention, the unsafe injection rate in the experimental group decreased from 27.8% to 21.7%, while in the control group injection the unsafe injection rate rose from 26.0% to 27.9%, with significant difference (Pinjection rate in the experimental group declined to 18.4% while the unsafe injection rate in the control group also dropped to 22.4%, with significant difference (Pinjection rate was decreased in the experimental group at different intervention points, with significant difference (Psafe injection behavior scores in the experimental group were higher than those in the control group after the intervention of 1 month and 6 month intervention (Psafe injection, distribution of safe injection guide, and comprehensive intervention model can significantly change the primary care practitioners' behaviors in unsafe injections and it is worth promoting.

Safe handling, transport and storage of plutonium. Proceedings of a technical committee meeting held in Vienna, 18-21 October 1993

International Nuclear Information System (INIS)

1994-10-01

Plutonium inventories and utilization rates worldwide are growing. It is important for nuclear power programmes everywhere that no incidents or accidents with plutonium occur. It is therefore important that all who deal with plutonium, do so safely. All those who deal with plutonium should have available the best information on safety handling and storage. Several countries have mature plutonium programmes. However, information exchange on plutonium has been limited. This has precluded the development until now of consensus documentation on safe handling and storage of plutonium. The Technical Committee has been established to address these problems and this Technical Document is the first product in this process. The purpose of the meeting was to bring together experts with significant experience in handling, transporting and storing plutonium; to exchange information and experiences dealing with plutonium at their facilities; to describe their practices (guidelines, procedures, regulations, etc.) for safely dealing with plutonium; to assess the need to develop and publish a consensus plutonium safety practices document(s), and to recommend possible future IAEA activities in this technical area.

Building world-wide nuclear industry success stories - Safe management of nuclear waste and used nuclear fuel

International Nuclear Information System (INIS)

Saint-Pierre, S.

2005-01-01

Full text: This WNA Position Statement summarizes the worldwide nuclear industry's record, progress and plans in safely managing nuclear waste and used nuclear fuel. The global industry's safe waste management practices cover the entire nuclear fuel-cycle, from the mining of uranium to the long-term disposal of end products from nuclear power reactors. The Statement's aim is to provide, in clear and accurate terms, the nuclear industry's 'story' on a crucially important subject often clouded by misinformation. Inevitably, each country and each company employs a management strategy appropriate to a specific national and technical context. This Position Statement reflects a confident industry consensus that a common dedication to sound practices throughout the nuclear industry worldwide is continuing to enhance an already robust global record of safe management of nuclear waste and used nuclear fuel. This text focuses solely on modern civil programmes of nuclear-electricity generation. It does not deal with the substantial quantities of waste from military or early civil nuclear programmes. These wastes fall into the category of 'legacy activities' and are generally accepted as a responsibility of national governments. The clean-up of wastes resulting from 'legacy activities' should not be confused with the limited volume of end products that are routinely produced and safely managed by today's nuclear energy industry. On the significant subject of 'Decommissioning of Nuclear Facilities', which is integral to modern civil nuclear power programmes, the WNA will offer a separate Position Statement covering the industry's safe management of nuclear waste in this context. The safe management of nuclear waste and used nuclear fuel is a widespread, well-demonstrated reality. This strong safety record reflects a high degree of nuclear industry expertise and of industry responsibility toward the well-being of current and future generations. Accumulating experience and

Guidelines for safe design of shipping packages against brittle fracture

International Nuclear Information System (INIS)

1993-08-01

In 1992, the ninth meeting of the Standing Advisory Group on the Safe Transport of Radioactive Materials recommended the publication of this TECDOC in an effort to promote the widest debate on the criteria for the brittle fracture safe design of transport packages. The published IAEA advice on the influence of brittle fracture on material integrity is contained in Appendix IX of the Advisory Material for the IAEA Regulations for the Safety Transport of Radioactive Material (1985 Edition, as amended 1990), Safety Series No. 37. This guidance is limited in scope, dealing only with ferritic steels in general terms. It is becoming more common for designers to specify materials other than austenitic stainless steel for packaging components. The data on ferritic steels cannot be assumed to apply to other metals, hence the need for further guidance on the development of relationships describing material properties at low temperatures. The methods described in this TECDOC will be considered by the Revision Panel for inclusion in the 1996 Edition of the IAEA Regulations for the Safe Transport of Radioactive Material and the supporting documents. If accepted by the Revision Panel, this advice will be a candidate for upgrading to a Safety Practice. In the interim period, this TECDOC offers provisional advice on brittle fracture evaluation. It is acknowledged that, at this stage, the views expressed do not necessarily reflect those of the governments of Member States or organizations under whose auspices this manuscript was produced.

Kutty, V. Raman; Sarma, P. Sankara; Dangal, Ganesh

2017-01-01

Despite various efforts to increase the utilization of skilled birth attendants (SBA), nearly two-thirds of deliveries take place at home without the assistance of SBAs in Nepal. We hypothesized that the ability of women to take decisions about their own lives—women’s autonomy—plays an important part in birth choices. To know this, we conducted a community-based cross-sectional study for assessing women’s autonomy and utilization of safe delivery care service in Kapilvastu district of Nepal from June to October 2014. We used multivariate modeling to associate socioeconomic factors and women’s autonomy with the utilization of safe delivery care services. Just over one-third of women sought institutional delivery care during the birth of their last child. Out of the total deliveries at health facilities, nearly 58% women visited health facility for self-reported emergency obstructive care. Only 6.2% home deliveries were handled by health workers and 14.7% women used the safe delivery kit for home delivery care. Higher levels of women’s education had a strong positive association (odds ratio = 24.11, CI = 9.43–61.64) with institutional delivery care. Stratified analysis showed that when the husband is educated, women’s education seems to work partly through their autonomy in decision making. Educational status of women emerged as one of the key predictors of the utilization of delivery care services in Kapilvastu district. Economic status of household and husband’s education are other dominant predictors of the utilization of safe delivery care services. Improving the economic and educational status may be the way out for improving the proportion of institutional deliveries. Women’s autonomy may be an important mediating factor in this pathway.

Managing Cassini Safe Mode Attitude at Saturn

Burk, Thomas A.

2010-01-01

The Cassini spacecraft was launched on October 15, 1997 and arrived at Saturn on June 30, 2004. It has performed detailed observations and remote sensing of Saturn, its rings, and its satellites since that time. In the event safe mode interrupts normal orbital operations, Cassini has flight software fault protection algorithms to detect, isolate, and recover to a thermally safe and commandable attitude and then wait for further instructions from the ground. But the Saturn environment is complex, and safety hazards change depending on where Cassini is in its orbital trajectory around Saturn. Selecting an appropriate safe mode attitude that insures safe operation in the Saturn environment, including keeping the star tracker field of view clear of bright bodies, while maintaining a quiescent, commandable attitude, is a significant challenge. This paper discusses the Cassini safe table management strategy and the key criteria that must be considered, especially during low altitude flybys of Titan, in deciding what spacecraft attitude should be used in the event of safe mode.

Based on survey that conducted by Multi-Center Study in Southeast Asia, Indonesia was on the top four position in number of patients with hearing disability (4.6%. Therefore, the existence of Sign Language recognition is important. Some research has been conducted on this field. Many neural network types had been used for recognizing many kinds of sign languages. However, their performance are need to be improved. This work focuses on the ASL (Alphabet Sign Language in SIBI (Sign System of Indonesian Language which uses one hand and 26 gestures. Here, thirty four features were extracted by using Leap Motion. Further, a new method, Rule Based-Backpropagation Genetic Al-gorithm Neural Network (RB-BPGANN, was used to recognize these Sign Languages. This method is combination of Rule and Back Propagation Neural Network (BPGANN. Based on experiment this pro-posed application can recognize Sign Language up to 93.8% accuracy. It was very good to recognize large multiclass instance and can be solution of overfitting problem in Neural Network algorithm.

Working safely with radioactive materials

International Nuclear Information System (INIS)

Davies, Wynne

1993-01-01

In common with exposure to many other laboratory chemicals, exposure to ionising radiations and to radioactive materials carries a small risk of causing harm. Because of this, there are legal limits to the amount of exposure to ionising radiations at work and special rules for working with radioactive materials. Although radiation protection is a complex subject it is possible to simplify to 10 basic things you should do -the Golden Rules. They are: 1) understand the nature of the hazard and get practical training; 2) plan ahead to minimise time spent handling radioactivity; 3) distance yourself appropriately from sources of radiation; 4) use appropriate shielding for the radiation; 5) contain radioactive materials in defined work areas; 6) wear appropriate protective clothing and dosimeters; 7) monitor the work area frequently for contamination control; 8) follow the local rules and safe ways of working; 9) minimise accumulation of waste and dispose of it by appropriate routes, and 10) after completion of work, monitor, wash, and monitor yourself again. These rules are expanded in this article. (author)

The US Department of Energy (DOE) is sponsoring SUNRAYCE 93 to advance tile technology and use of photovoltaics and electric vehicles. Participants will use cars powered by photovoltaic modules and lead-acid storage batteries. This brochure, prepared for students and faculty participating in this race, outlines the health hazards presented by these electrical systems and gives guidance on strategies for their safe usage. At the outset, it should be noted that working with photovoltaic systems and batteries requires electric vehicle drivers and technicians to have 'hands-on' contact with the car on a daily basis. It is important that no one work near a photovoltaic energy system or battery, either in a vehicle or on the bench, unless they familiarize themselves with the components in use and know and observe safe work practices including the safety precautions described in the manuals provided by the various equipment vendors and this document.

Inherently safe light water reactors

Ise, Takeharu

1987-01-01

Today's large nuclear power reactors of world-wise use have been designed based on the philosophy. It seems that recent less electricity demand rates, higher capital cost and the TMI accident let us acknowledge relative small and simplified nuclear plants with safer features, and that Chernobyl accident in 1983 underlines the needs of intrinsic and passive safety characteristics. In such background, several inherently safe reactor concepts have been presented abroad and domestically. First describing 'Can inherently safe reactors be designed,' then I introduce representative reactor concepts of inherently safe LWRs advocated abroad so far. All of these innovative reactors employ intrinsic and passive features in their design, as follows: (1) PIUS, an acronym for Process Inherent Ultimate Safety, or an integral PWR with passive heat sink and passive shutdown mechanism, advocated by ASEA-ATOM of Sweden. (2) MAP(Minimum Attention Plant), or a self-pressurized, natural circulation integral PWR, promoted by CE Inc. of the U.S. (3) TPS(TRIGA Power System), or a compact PWR with passive heat sink and inherent fuel characteristics of large prompt temperature coefficient, prompted by GA Technologies Inc. of the U.S. (4) PIUS-BWR, or an inherently safe BWR employing passively actuated fluid valves, in competition with PIUS, prompted by ORNL of the U.S. Then, I will describe the domestic trends in Japan and the innovative inherently safe LWRs presented domestically so far.

Safeguards Automated Facility Evaluation (SAFE) methodology

International Nuclear Information System (INIS)

Chapman, L.D.; Grady, L.M.; Bennett, H.A.; Sasser, D.W.; Engi, D.

1978-01-01

The SAFE procedure is an efficient method of evaluating the physical protection system of a nuclear facility. Since the algorithms used in SAFE for path generation and evaluation are analytical, many paths can be evaluated with a modest investment in computer time. SAFE is easy to use because the information required is well-defined and the interactive nature of this procedure lends itself to straightforward operation. The modular approach that has been taken allows other functionally equivalent modules to be substituted as they become available. The SAFE procedure has broad applications in the nuclear facility safeguards field as well as in the security field in general. Any fixed facility containing valuable materials or components to be protected from theft or sabotage could be analyzed using this same automated evaluation technique

There is renewed interest in second-stage labor practices as recent evidence has challenged historical perspectives on safe duration of secondstage labor. Traditional practices and routine interventions during second-stage have uncertain benefit for low-risk women and may result in cesarean birth. The purpose of this quality improvement project was to implement an interdisciplinary second-stage practice bundle to promote safe outcomes including method of birth and women's birth experience. Standardized second-stage labor evidence-based practice recommendations structured into a 5 Ps practice bundle (patience, positioning, physiologic resuscitation, progress, preventing urinary harm) were implemented across 34 birthing hospitals in Trinity Health system. Significant improvements were observed in second-stage practices. Association of Women's Health, Obstetric and Neonatal Nurses' perinatal nursing care quality measure Second-Stage of Labor: Mother-Initiated Spontaneous Pushing significantly improved [pre-implementation 43% (510/1,195), post-implementation 76% (1,541/2,028), p labor practices derived from the Association of Women's Health, Obstetric and Neonatal Nurses and American College of Nurse-Midwives professional guidelines achieved our goals of safely reducing primary cesarean birth among low-risk nulliparous women, and optimizing maternal and fetal outcomes associated with labor and birth. By minimizing routine interventions, nurses support physiologic birth and improve women's birth satisfaction.

Curiosity's Autonomous Surface Safing Behavior Design

Science.gov (United States)

Neilson, Tracy A.; Manning, Robert M.

2013-01-01

The safing routines on all robotic deep-space vehicles are designed to put the vehicle in a power and thermally safe configuration, enabling communication with the mission operators on Earth. Achieving this goal is made a little more difficult on Curiosity because the power requirements for the core avionics and the telecommunication equipment exceed the capability of the single power source, the Multi-Mission Radioisotope Thermoelectric Generator. This drove the system design to create an operational mode, called "sleep mode", where the vehicle turns off most of the loads in order to charge the two Li-ion batteries. The system must keep the vehicle safe from over-heat and under-heat conditions, battery cell failures, under-voltage conditions, and clock failures, both while the computer is running and while the system is sleeping. The other goal of a safing routine is to communicate. On most spacecraft, this simply involves turning on the receiver and transmitter continuously. For Curiosity, Earth is above the horizon only a part of the day for direct communication to the Earth, and the orbiter overpass opportunities only occur a few times a day. The design must robustly place the Rover in a communicable condition at the correct time. This paper discusses Curiosity's autonomous safing behavior and describes how the vehicle remains power and thermally safe while sleeping, as well as a description of how the Rover communicates with the orbiters and Earth at specific times.

Unsafe injections and substandard waste management are public health issues exposing healthcare workers and the community to the risk of infections. The objective of this study was to assess the knowledge and practice of safe injections and health care waste management among healthcare workers at a regional hospital in northern Tanzania. This cross sectional descriptive study was conducted in a regional hospital in northern Tanzania. Data was collected through a self-administered questionnaire with additional observations of the incinerator, injections, waste practices, and the availability of medical supplies. Data was analysed in SPSS descriptive statistics and chi-square tests were performed. A total of 223 of 305 (73%) healthcare workers from different cadres were included in the study. The majority of healthcare workers had adequate knowledge and practice of safe injections, but inadequate knowledge about waste management. The majority of the staff reported knowledge of HIV as a risk factor, however, had less knowledge about other blood-borne infections. Guidelines and posters on post exposure prophylaxes and waste management -were present at the hospital, however, the incinerator had no fence or temperature gauge. In conclusion, healthcare workers reported good knowledge and practice of injections, and high knowledge of HIV transmission routes. However, the hospital is in need of a well functioning incinerator and healthcare workers require sufficient medical supplies. There was a need for continual training about health care waste management and avoidance of blood-borne pathogens that may be transmitted through unsafe injections or poor health care waste management.

Perspectives from practice: complexities of personal care workers.

Science.gov (United States)

Martyn, Julie-Anne; Zanella, Sally; Wilkinson, Adele

2017-11-14

Personal care workers (PCWs) make up the bulk of the workforce in residential and community care services. The knowledge and skill set needed for safe and effective practice in care settings is extensive. A diverse range of registered training organisations (RTOs) offering Certificate III and IV in Individual Support (aging, home and community) are tasked with producing job-ready PCWs. However, the curricula of these programs vary. Additionally, a national code of conduct for healthcare workers became effective in October 2015 as a governance framework for PCWs. The language of the code statements is ambiguous making it unclear how this framework should be translated by RTOs and applied in the preservice practice preparation of PCWs. Employers of PCWs need to feel confident that the content of the preservice education of PCWs satisfactorily prepares them for the diverse contexts of their practice. Likewise, the health professionals who supervise PCWs must be assured about the knowledge and skills of the PCW if they are to safely delegate care activities. The perspectives presented in this discussion make it clear that investigation into the nebulous nature of PCW education, regulation and practice is needed to identify the shortcomings and enable improved practice.

Comparing the level of dexterity offered by latex and nitrile SafeSkin gloves.

An increase in the occurrence of latex allergy has been concurrent with the increasing use of latex gloves by laboratory and healthcare workers. In recent years nitrile gloves have been used to replace latex gloves to prevent latex allergy. Nitrile gloves offer a comparable level of protection against chemical and biological agents and are more puncture resistant. However, if manual dexterity is compromised by nitrile gloves to a greater degree than latex then this may increase the risk of sharps injuries. The Purdue pegboard test, which measures both gross and fine finger dexterity, was used to test the dexterity levels of two glove types used at HPA CEPR; Kimberly-Clark SafeSkin nitrile and latex laboratory gloves. There was a statistically significant 8.6% increase in fine finger dexterity provided by latex compared with nitrile SafeSkin laboratory gloves but no difference in gross dexterity between the glove types. There was no significant relationship between glove dexterity and age or gender. The selection of glove size was influenced by the digit length of participants. Moreover, those with longer, thinner fingers appeared to have an advantage when using nitrile SafeSkin gloves. The level of dexterity provided by latex and nitrile SafeSkin gloves for tasks on a gross dexterity level are comparable and health workers will benefit from the non-allergenic properties of nitrile. For tasks requiring fine finger dexterity nitrile SafeSkin gloves may impede dexterity. Despite this, the degree of restriction appears to have a negligible impact on safety in this study when compared with the risk of latex sensitization and subsequent allergy. In addition to glove material, working practices must also take into account glove size, fit, grip and thickness, as these factors can all influence dexterity.

To describe the strategy employed by Andalusian public health service hospitals to foster safe medication use. The self-evaluation questionnaire on drug system safety in hospitals, adapted by the Spanish Institute for Safe Medication Practices was used as a fundamental tool to that end. The strategy is developed in several phases. We analyse the report evaluating drug system safety in Andalusian public hospitals published by the Spanish Ministry of Health and Consumption in 2008 and establish a grading system to assess safe medication practices in Andalusian hospitals and prioritise areas needing improvement. We developed a catalogue of best practices available in the web environment belonging to the Andalusian health care quality agency's patient safety observatory. We publicised the strategy through training seminars and implemented a system allowing hospitals to evaluate the degree of compliance for each of the best practices, and based on that system, we were able to draw up a map of centres of reference. We found areas for improvement among several of the questionnaire's fundamental criteria. These areas for improvement were related to normal medication procedures in daily clinical practice. We therefore wrote 7 best practice guides that provide a cross-section of the assessment components of the questionnaire related to the clinical process needing improvement. The self-evaluation questionnaire adapted by ISMP-Spain is a good tool for designing a systematic, rational intervention to promote safe medication practices and intended for a group of hospitals that share the same values.

Pushover, Response Spectrum and Time History Analyses of Safe Rooms in a Poor Performance Masonry Building

International Nuclear Information System (INIS)

Mazloom, M.

2008-01-01

The idea of safe room has been developed for decreasing the earthquake casualties in masonry buildings. The information obtained from the previous ground motions occurring in seismic zones expresses the lack of enough safety of these buildings against earthquakes. For this reason, an attempt has been made to create some safe areas inside the existing masonry buildings, which are called safe rooms. The practical method for making these safe areas is to install some prefabricated steel frames in some parts of the existing structure. These frames do not carry any service loads before an earthquake. However, if a devastating earthquake happens and the load bearing walls of the building are destroyed, some parts of the floors, which are in the safe areas, will fall on the roof of the installed frames and the occupants who have sheltered there will survive. This paper presents the performance of these frames located in a destroying three storey masonry building with favorable conclusions. In fact, the experimental pushover diagram of the safe room located at the ground-floor level of this building is compared with the analytical results and it is concluded that pushover analysis is a good method for seismic performance evaluation of safe rooms. For time history analysis the 1940 El Centro, the 2003 Bam, and the 1990 Manjil earthquake records with the maximum peak accelerations of 0.35g were utilized. Also the design spectrum of Iranian Standard No. 2800-05 for the ground kind 2 is used for response spectrum analysis. The results of time history, response spectrum and pushover analyses show that the strength and displacement capacity of the steel frames are adequate to accommodate the distortions generated by seismic loads and aftershocks properly

USING THE SAFE SYSTEM APPROACH TO KEEP OLDER DRIVERS SAFELY MOBILE

Directory of Open Access Journals (Sweden)

Jim LANGFORD

2006-01-01

Full Text Available In 2003, Australian road transport jurisdictions collectively accepted that the greatest road safety gains would be achieved through adopting a Safe System approach, derived from Sweden's Vision Zero and the Netherlands' Sustainable Safety strategies. A key objective of all three approaches is to manage vehicles, the road infrastructure, speeds, road users and the interactions between these components, to ensure that in the event of crashes, crash energies will remain at levels that minimize the probability of death and serious injury. Older drivers pose a particular challenge to the Safe System approach, given particularly their greater physical frailty, their driving patterns and for some at least, their reduced fitness to drive. This paper has analyzed the so-called ‘older driver problem’ and identified a number of key factors underpinning their crash levels, for which countermeasures can be identified and implemented within a Safe System framework. The recommended countermeasures consist of: (1 safer roads, through a series of design improvements particularly governing urban intersections; (2 safer vehicles, through both the promotion of crashworthiness as a critical consideration when purchasing a vehicle and the wide use of developed and developing ITS technologies; (3 safer speeds especially at intersections; and (4 safer road users, through both improved assessment procedures to identify the minority of older drivers with reduced fitness to drive and educational efforts to encourage safer driving habits particularly but not only through self-regulation.

Feeling safe during an inpatient hospitalization: a concept analysis.

This paper aims to explore the critical attributes of the concept feeling safe. The safe delivery of care is a high priority; however; it is not really known what it means to the patient to 'feel safe' during an inpatient hospitalization. This analysis explores the topic of safety from the patient's perspective. Concept analysis. The data bases of CINAHL, Medline, PsychInfo and Google Scholar for the years 1995-2012 were searched using the terms safe and feeling safe. The eight-step concept analysis method of Walker and Avant was used to analyse the concept of feeling safe. Uses and defining attributes, as well as identified antecedents, consequences and empirical referents, are presented. Case examples are provided to assist in the understanding of defining attributes. Feeling safe is defined as an emotional state where perceptions of care contribute to a sense of security and freedom from harm. Four attributes were identified: trust, cared for, presence and knowledge. Relationship, environment and suffering are the antecedents of feeling safe, while control, hope and relaxed or calm are the consequences. Empirical referents and early development of a theory of feeling safe are explored. This analysis begins the work of synthesizing qualitative research already completed around the concept of feeling safe by defining the key attributes of the concept. Support for the importance of developing patient-centred models of care and creating positive environments where patients receive high-quality care and feel safe is provided. © 2014 John Wiley & Sons Ltd.

A new approach to design safe CNTs with an understanding of redox potential.

Tsuruoka, Shuji; Cassee, Flemming R; Castranova, Vincent

2013-09-02

Carbon nanotubes (CNTs) are being increasingly industrialized and applied for various products. As of today, although several toxicological evaluations of CNTs have been conducted, designing safer CNTs is not practiced because reaction kinetics of CNTs with bioactive species is not fully understood. The authors propose a kinetic mechanism to establish designing safe CNTs as a new goal. According to a literature search on the behavior of CNTs and the effects of impurities, it is found that chemical reactions on CNT surface are attributed to redox reactions involving metal impurities and carbon structures at the CNT surface. A new goal is proposed to design safer CNTs using the redox potential hypothesis. The value of this hypothesis must be practically investigated and proven through the further experiments.

SAFE USE OF DRUGS DURING PREGNANCY IN FOCUS OF INTERNATIONAL PRACTICE OF PHARMACOVIGILANCE SYSTEM AND TERATOLOGICAL INFORMATION SERVICE ORGANIZATION

Full Text Available The safe use of drugs during pregnancy is essential to optimize the health of both pregnant woman and her future child. At the same time obstetrician-gynecologists often face the lack of evidence-based information on the use of drugs and leave the issue to the woman herself — whether the treatment benefit to the mother outweighs risks to the unborn child — relying on the limited amount of scientific data. Preconception discussion of actual risks and safe treatment reduces patient fears and maximizes the emphasis on the therapy safety. At the same time, the lack of adequate information on safety for the majority of drugs used by pregnant women combined with the need to make appropriate treatment decisions and communicate drug risk information to a potentially vulnerable population is the most challenging and critical issue of pregnant women's health.

Runyan, Carol W; Brooks-Russell, Ashley; Betz, Marian E

2018-06-07

Counseling about reducing access to lethal means of suicide, especially firearms, is a recommended practice in emergency departments (EDs) but does not occur routinely. Understanding influencers of decisions makers in health care (ED nurse leaders, mental health providers) and temporary firearm storage (law enforcement and gun retailers) could enhance practice. We surveyed these 4 groups in the 8-state region of the Mountain West. For ED nurse leaders (n = 190), hospital legal, risk management, and quality improvement representatives, and the ED nursing director were most often cited as influential, whereas mental health providers (n = 67) cited their own team. Law enforcement officials (n = 448) identified the overall community and leaders of mental health or general health organizations as influential. Firearm retailers (n = 95) cited local law enforcement and national firearm organizations. Advocacy from influential groups may encourage efforts to provide lethal means counseling and temporary off-site storage of firearms for suicide prevention.

To describe the design, implementation, and early experience of the SafeMed program, which uses certified pharmacy technicians in a novel expanded role as community health workers (CPhT-CHWs) to improve transitions of care. A large nonprofit health care system serving the major medically underserved areas and geographic hotspots for readmissions in Memphis, TN. The SafeMed program is a care transitions program with an emphasis on medication management designed to use low-cost health workers to improve transitions of care from hospital to home for superutilizing patients with multiple chronic conditions and polypharmacy. CPhT-CHWs were given primary responsibility for patient outreach after hospital discharge with the use of home visits and telephone follow-up. SafeMed program CPhT-CHWs served as pharmacist extenders, obtaining medication histories, assisting in medication reconciliation and identification of potential drug therapy problems (DTPs), and reinforcing medication education previously provided by the pharmacist per protocol. CPhT-CHW training included patient communication skills, motivational interviewing, medication history taking, teach-back techniques, drug disposal practices, and basic disease management. Some CPhT-CHWs experienced difficulties adjusting to an expanded scope of practice. Nonetheless, once the Tennessee Board of Pharmacy affirmed that envisioned SafeMed CPhT-CHW roles were consistent with Board rules, additional responsibilities were added for CPhT-CHWs to enhance their effectiveness. Patient outreach teams including CPhT-CHWs achieved increases in home visit and telephone follow-up rates and were successful in helping identify potential DTPs. The early experience of the SafeMed program demonstrates that CPhT-CHWs are well suited for novel expanded roles to improve care transitions for superutilizing populations. CPhT-CHWs can identify and report potential DTPs to the pharmacist to help target medication therapy management. Critical

Description of safety problems and harm in general practices has previously relied on information from health professionals, with scarce attention paid to experiences of patients. To examine patient-reported experiences and outcomes of patient safety in primary care. Cross-sectional study in 45 general practices across five regions in the north, centre, and south of England. A version of the Patient Reported Experiences and Outcomes of Safety in Primary Care (PREOS-PC) questionnaire was sent to a random sample of 6736 patients. Main outcome measures included 'practice activation' (what a practice does to create a safe environment); 'patient activation' (how proactive are patients in ensuring safe healthcare delivery); 'experiences of safety events' (safety errors); 'outcomes of safety' (harm); and 'overall perception of safety' (how safe patients rate their practice). Questionnaires were returned by 1244 patients (18.4%). Scores were high for 'practice activation' (mean [standard error] = 80.4 out of 100 [2.0]) and low for 'patient activation' (26.3 out of 100 [2.6]). Of the patients, 45% reported experiencing at least one safety problem in the previous 12 months, mostly related to appointments (33%), diagnosis (17%), patient provider communication (15%), and coordination between providers (14%). Twenty-three per cent of the responders reported some degree of harm in the previous 12 months. The overall assessment of level of safety of practices was generally high (86.0 out of 100 [16.8]). Priority areas for patient safety improvement in general practices in England include appointments, diagnosis, communication, coordination, and patient activation. © British Journal of General Practice 2017.

SafeNet: a methodology for integrating general-purpose unsafe devices in safe-robot rehabilitation systems.

Vicentini, Federico; Pedrocchi, Nicola; Malosio, Matteo; Molinari Tosatti, Lorenzo

2014-09-01

Robot-assisted neurorehabilitation often involves networked systems of sensors ("sensory rooms") and powerful devices in physical interaction with weak users. Safety is unquestionably a primary concern. Some lightweight robot platforms and devices designed on purpose include safety properties using redundant sensors or intrinsic safety design (e.g. compliance and backdrivability, limited exchange of energy). Nonetheless, the entire "sensory room" shall be required to be fail-safe and safely monitored as a system at large. Yet, sensor capabilities and control algorithms used in functional therapies require, in general, frequent updates or re-configurations, making a safety-grade release of such devices hardly sustainable in cost-effectiveness and development time. As such, promising integrated platforms for human-in-the-loop therapies could not find clinical application and manufacturing support because of lacking in the maintenance of global fail-safe properties. Under the general context of cross-machinery safety standards, the paper presents a methodology called SafeNet for helping in extending the safety rate of Human Robot Interaction (HRI) systems using unsafe components, including sensors and controllers. SafeNet considers, in fact, the robotic system as a device at large and applies the principles of functional safety (as in ISO 13489-1) through a set of architectural procedures and implementation rules. The enabled capability of monitoring a network of unsafe devices through redundant computational nodes, allows the usage of any custom sensors and algorithms, usually planned and assembled at therapy planning-time rather than at platform design-time. A case study is presented with an actual implementation of the proposed methodology. A specific architectural solution is applied to an example of robot-assisted upper-limb rehabilitation with online motion tracking. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Existing guidelines rarely address the practical issues faced by multidisciplinary ICU teams attempting to translate evidence into practice. We present a comprehensive strategy for safe mobilization utilized in our ICU, incorporating the combined skills of medical, nursing, and physiotherapy staff to achieve safe outcomes and establish a culture which prioritizes this intervention.Methods: A raft of tools and strategies are described to facilitate mobilization in ICU by the multidisciplinary team. Patients without safe unsupported sitting balance and without ≥3/5 (Oxford scale strength in the lower limbs commence phase 1 mobilization, including training of sitting balance and use of the tilt table. Phase 2 mobilization involves supported or active weight-bearing, incorporating gait harnesses if necessary.

openPDS: protecting the privacy of metadata through SafeAnswers.

Directory of Open Access Journals (Sweden)

Yves-Alexandre de Montjoye

Full Text Available The rise of smartphones and web services made possible the large-scale collection of personal metadata. Information about individuals' location, phone call logs, or web-searches, is collected and used intensively by organizations and big data researchers. Metadata has however yet to realize its full potential. Privacy and legal concerns, as well as the lack of technical solutions for personal metadata management is preventing metadata from being shared and reconciled under the control of the individual. This lack of access and control is furthermore fueling growing concerns, as it prevents individuals from understanding and managing the risks associated with the collection and use of their data. Our contribution is two-fold: (1 we describe openPDS, a personal metadata management framework that allows individuals to collect, store, and give fine-grained access to their metadata to third parties. It has been implemented in two field studies; (2 we introduce and analyze SafeAnswers, a new and practical way of protecting the privacy of metadata at an individual level. SafeAnswers turns a hard anonymization problem into a more tractable security one. It allows services to ask questions whose answers are calculated against the metadata instead of trying to anonymize individuals' metadata. The dimensionality of the data shared with the services is reduced from high-dimensional metadata to low-dimensional answers that are less likely to be re-identifiable and to contain sensitive information. These answers can then be directly shared individually or in aggregate. openPDS and SafeAnswers provide a new way of dynamically protecting personal metadata, thereby supporting the creation of smart data-driven services and data science research.

Certainty, leaps of faith, and tradition: rethinking clinical interventions.

Dzurec, L C

1998-12-01

Clinical decision making requires that clinicians think quickly and in ways that will foster optimal, safe client care. Tradition influences clinical decision making, enhancing efficiency of resulting nursing action; however, since many decisions must be based on data that are either uncertain, incomplete, or indirect, clinicians are readily ensnared in processes involving potentially faulty logic associated with tradition. The author addresses the tenacity of tradition and then focuses on three processes--consensus formation, the grounding of certainty in inductive reasoning, and affirming the consequent--that have affected clinical decision making. For some recipients of care, tradition has had a substantial and invalid influence on their ability to access care.

Cho, Sumi; Lee, Eunjoo

2017-12-01

Recently, the patient's role in preventing adverse events has been emphasized. Patients who are more knowledgeable about safety issues are more likely to engage in safety initiatives. Therefore, nurses need to develop techniques and tools that increase patients' knowledge in preventing adverse events. For this reason, an educational smartphone application for patient safety called "Safe Patients" was developed through an iterative process involving a literature review, expert consultations, and pilot testing of the application. To determine the effect of "Safe Patients," it was implemented for patients in surgical units in a tertiary hospital in South Korea. The change in patients' knowledge about patient safety was measured using seven true/false questions developed in this study. A one-group pretest and posttest design was used, and a total of 123 of 190 possible participants were tested. The percentage of correct answers significantly increased from 64.5% to 75.8% (P effectively improve patients' knowledge of safety issues. This will ultimately empower patients to engage in safe practices and prevent adverse events related to surgery.

Safe management of radioactive waste in Ghana

2000-01-01

The Ghana Atomic Energy Commission was established in 1963 by an Act of Parliament, Act 204 for the Promotion, Development and Peaceful Application of Nuclear Techniques for the Benefit of Ghana. As in many developing countries the use of nuclear application is growing considerably in importance within the national economy. The Radiation Protection Board was established as the national regulatory authority and empowered by the Radiation Protection Instrument LI 1559 (1993). The above regulations, Act 204 and LI 1559 provided a minimum legal basis for regulatory control of radioactive waste management as it deals with waste management issues in a very general way and is of limited practical use to the waste producer. Hence the National Radioactive Waste Management Centre was established in July 1995 to carry out waste safety operations in Ghana. This paper highlights steps that have been taken to develop a systemic approach for the safe management of radioactive waste in the future and those already in existence. (author)

Prospects for inherently safe reactors

Barkenbus, J.N.

1988-01-01

Public fears over nuclear safety have led some within the nuclear community to investigate the possibility of producing inherently safe nuclear reactors; that is, reactors that are transparently incapable of producing a core melt. While several promising designs of such reactors have been produced, support for large-scale research and development efforts has not been forthcoming. The prospects for commercialization of inherently safe reactors, therefore, are problematic; possible events such as further nuclear reactor accidents and superpower summits, could alter the present situation significantly.

Teaching Engineering Practices

Cunningham, Christine M.; Carlsen, William S.

2014-03-01

Engineering is featured prominently in the Next Generation Science Standards (NGSS) and related reform documents, but how its nature and methods are described is problematic. This paper is a systematic review and critique of that representation, and proposes that the disciplinary core ideas of engineering (as described in the NGSS) can be disregarded safely if the practices of engineering are better articulated and modeled through student engagement in engineering projects. A clearer distinction between science and engineering practices is outlined, and prior research is described that suggests that precollege engineering design can strengthen children's understandings about scientific concepts. However, a piecemeal approach to teaching engineering practices is unlikely to result in students understanding engineering as a discipline. The implications for science teacher education are supplemented with lessons learned from a number of engineering education professional development projects.

Sociotechnical attributes of safe and unsafe work systems.

Kleiner, Brian M; Hettinger, Lawrence J; DeJoy, David M; Huang, Yuang-Hsiang; Love, Peter E D

2015-01-01

Theoretical and practical approaches to safety based on sociotechnical systems principles place heavy emphasis on the intersections between social-organisational and technical-work process factors. Within this perspective, work system design emphasises factors such as the joint optimisation of social and technical processes, a focus on reliable human-system performance and safety metrics as design and analysis criteria, the maintenance of a realistic and consistent set of safety objectives and policies, and regular access to the expertise and input of workers. We discuss three current approaches to the analysis and design of complex sociotechnical systems: human-systems integration, macroergonomics and safety climate. Each approach emphasises key sociotechnical systems themes, and each prescribes a more holistic perspective on work systems than do traditional theories and methods. We contrast these perspectives with historical precedents such as system safety and traditional human factors and ergonomics, and describe potential future directions for their application in research and practice. The identification of factors that can reliably distinguish between safe and unsafe work systems is an important concern for ergonomists and other safety professionals. This paper presents a variety of sociotechnical systems perspectives on intersections between social--organisational and technology--work process factors as they impact work system analysis, design and operation.

Each approach emphasises key sociotechnical systems themes, and each prescribes a more holistic perspective on work systems than do traditional theories and methods. We contrast these perspectives with historical precedents such as system safety and traditional human factors and ergonomics, and describe potential future directions for their application in research and practice. Practitioner Summary: The identification of factors that can reliably distinguish between safe and unsafe work systems is an important concern for ergonomists and other safety professionals. This paper presents a variety of sociotechnical systems perspectives on intersections between social–organisational and technology–work process factors as they impact work system analysis, design and operation.

Manufactured nanomaterials (MNMs) are regarded as key components of innovations in various fields with high potential impact (e.g., energy generation and storage, electronics, photonics, diagnostics, theranostics, or drug delivery agents). Widespread use of MNMs raises concerns about their safety for humans and the environment, possibly limiting the impact of the nanotechnology-based innovation. The development of safe MNMs and nanoproducts has to result in a safe as well as functional material or product. Its safe use, and disposal at the end of its life cycle must be taken into account too. However, not all MNMs are similarly useful for all applications, some might bear a higher hazard potential than others, and use scenarios could lead to different exposure probabilities. To improve both safety and efficacy of nanotechnology, we think that a new proactive approach is necessary, based on pre-regulatory safety assessment and dialogue between stakeholders. On the basis of the work carried out in different European Union (EU) initiatives, developing and integrating MNMs Safe-by-Design and Trusted Environments (NANoREG, ProSafe, and NanoReg2), we present our point of view here. This concept, when fully developed, will allow for cost effective industrial innovation, and an exchange of key information between regulators and innovators. Regulators are thus informed about incoming innovations in good time, supporting a proactive regulatory action. The final goal is to contribute to the nanotechnology governance, having faster, cheaper, effective, and safer nano-products on the market.

Safe havens in Europe: Switzerland and the ten dwarfs

Directory of Open Access Journals (Sweden)

Martin Paldam

2013-12-01

Full Text Available Eleven safe havens exist in Europe providing offshore banking and low taxes. Ten of these states are very small while Switzerland is moderately small. All 11countries are richer than their large neighbors. It is shown that causality is from small to safe haven towealth, and that theoretically equilibriums are likely to exist where a certain regulation is substantially lower in a small country than in its big neighbor. This generates a large capital inflow to the safe havens. The pool of funds that may reach the safe havens is shown to be huge. It is far in excess of the absorptive capacity of the safe havens, but it still explains, why they are rich. Microstates offer a veil of anonymity to funds passing through, and Switzerland offers safe storage of funds.

This paper shows that strict match pass-through funding of covered bonds provides safe and liquid mortgage bonds. Despite a 30% drop in house prices during the 2008 global crisis Danish mortgage bonds remained as liquid as most European government bonds. The Danish pass-through system effectively...... eliminates credit risk from the investor's perspective. Similar to other safe bonds, funding liquidity becomes the main driver of mortgage bond liquidity and this creates commonality in liquidity across markets and countries. These findings have implications for how to design a robust mortgage bond system...

Bio Design Facility is the specifically designed glass house for propagation, screening and analysis of high quality plant varieties developed through biotechnology or a combination of nuclear technology and biotechnology. High quality plant varieties especially genetically modified plants (GMO) require a special glass house facility for propagation and screening to isolate them from cross-pollinating with wild type varieties in surrounding ecosystem, and for carrying out evaluation of possible risks of the plants to human, animal and environment before they are proven safe for field trials or commercial release. This facility which was developed under the Ninth Malaysia Plan is classified as the Plant Containment Level 2 and is compliance with the bio safety regulations and guidance for the safe release of GMO according to Malaysian Bio safety Act 2007. Bio Design Facility is fully operational since 2010 and in 2012, it has also been certified as the glass house for post-entry quarantine by The Department of Agriculture. This paper summarizes the bio safety procedure for a safe, controlled and contained growing and evaluation of GMO in Bio Design Facility. This procedure covers the physical (containment and equipment's) and operational (including responsibility, code of practice, growing, decontamination and disposal of plant materials, emergency and contingency plan) aspects of the facility.

Learning From Critical Collective Spaces: Reflections on the Community-Diversity Dialectic in Safe Spaces

Directory of Open Access Journals (Sweden)

Jennifer Wallin-Ruschman

2016-05-01

Full Text Available Safe spaces have the potential to become prefigurative groups that aim to create social change. The idea of a safe space as a place separate and sheltered from dominant culture to mobilize for social change has gained traction in a number of academic and practical areas. However, safe spaces have the ability to be both progressive and regressive. To guide our discussion we utilize the concept of community-diversity dialectic to address the tension between these forces within two settings. First we discuss research in an upper level college course rooted in feminist praxis. Then we discuss a faith community’s use of adaptive liturgy with parishioners with intellectual disabilities. Following this discussion, we offer a new term, “critical collective spaces”, to better capture the work done in these spaces. We offer this alternative label to move popular and academic discourse away from debating about how “safe” these spaces are (or are not and toward a more nuanced discussion of the community-diversity dialectic and other tensions within these spaces. Our overall intention is to generate dialogue on the regressive and progressive aspects of these locations and to inform the activism and community building process within prefigurative politics more broadly.

IAEA Mission Says France Committed to Safe, Responsible Management of Radioactive Waste

International Nuclear Information System (INIS)

2018-01-01

An International Atomic Energy Agency (IAEA) team of experts said France demonstrated a comprehensive commitment to safety with a responsible approach to the management of radioactive waste and spent nuclear fuel. The team also made suggestions aimed at further enhancements and noted several good practices. The Integrated Review Service for Radioactive Waste and Spent Fuel Management, Decommissioning and Remediation (ARTEMIS) team concluded an 11-day mission to France on 24 January. The mission, requested by the Government of France, was hosted by the Directorate General of Energy and Climate (DGEC), with the participation of officials from several relevant organizations including the French National Radioactive Waste Agency (ANDRA) and the Nuclear Safety Authority (ASN), which is responsible for nuclear and radiation safety regulation in the country. ARTEMIS missions provide independent expert advice from an international team of specialists convened by the IAEA. Reviews are based on the IAEA safety standards as well as international good practices. The mission to France aimed to help the country meet European Union obligations that require an independent peer review of national programmes for the safe and responsible management of spent fuel and radioactive waste. Nuclear power currently generates more than 70 percent of France’s electricity. The country has 58 operating nuclear power reactors, which will require the continuing safe management of radioactive waste and spent fuel. France operates facilities for the disposal of very low-level and low-level wastes, and is developing a deep geological repository for the disposal of high-level waste.

Taking a leap of faith: Meaningful participation of people with experiences of homelessness in solutions to address homelessness

Directory of Open Access Journals (Sweden)

2015-12-01

Full Text Available Participation of people with experiences of homelessness is critical to the development of meaningful strategies to end homelessness. The purpose of this study was to gain insights from people who have been homeless in a mid-sized Canadian city, as to strategies that facilitate meaningful participation in solutions to end homelessness. Within an overarching framework of collaborative research, we collected data through seven focus groups and employed interpretive description as our approach to data analysis. In our analysis, we identified both exclusionary and inclusionary forces that impact participation. Exclusionary forces included being ‘caught in the homelessness industry’, ‘homelessness is a full time job’ and facing stigma/discrimination that make participation a ‘leap of faith’. Inclusionary forces included earning respect and building trust to address unequal power relations, and restoring often ‘taken for granted’ social relations. Specific strategies to enhance participation include listening, valuing skills and stories, and supporting advocacy efforts. The study findings illuminate ways in which power imbalances are lived out in the daily lives of people who experience homelessness, as well as mitigating forces that provide direction as to strategies for addressing power inequities that seek to make participation and social inclusion meaningful.

Operating and maintaining a tornado safe room can be critical to the effective continuity of business operations because a firm's most valuable asset is its people. This paper describes aspects of operations and maintenance (O&M) for existing tornado safe rooms as well as a few planning and design aspects that affect the ultimate operation of a safe room for situations where a safe room is planned, but not yet constructed. The information is based on several Federal Emergency Management Agency safe room publications that provide guidance on emergency management and operations, as well as the design and construction of tornado safe rooms.

A durability model incorporating safe life methodology and damage tolerance approach to assess first inspection and maintenance period for structures

International Nuclear Information System (INIS)

Xiong, J.J.; Shenoi, R.A.

2009-01-01

This paper outlines a new durability model to assess the first inspection and maintenance period for structures. Practical scatter factor formulae are presented to determine the safe fatigue crack initiation and propagation lives from the results of a single full-scale test of a complete structure. New theoretical solutions are proposed to determine the s a -s m -N surfaces of fatigue crack initiation and propagation. Prediction techniques are then developed to establish the relationship equation between safe fatigue crack initiation and propagation lives with a specific reliability level using a two-stage fatigue damage cumulative rule. A new durability model incorporating safe life and damage tolerance design approaches is derived to assess the first inspection and maintenance period. Finally, the proposed models are applied to assess the first inspection and maintenance period of a fastening structure at the root of helicopter blade.

Safe actinide disposition in molten salt reactors

International Nuclear Information System (INIS)

Gat, U.

1997-01-01

Safe molten salt reactors (MSR) can readily accommodate the burning of all fissile actinides. Only minor compromises associated with plutonium are required. The MSRs can dispose safely of actinides and long lived isotopes to result in safer and simpler waste. Disposing of actinides in MSRs does increase the source term of a safety optimized MSR. It is concluded that the burning and transmutation of actinides in MSRs can be done in a safe manner. Development is needed for the processing to handle and separate the actinides. Calculations are needed to establish the neutron economy and the fuel management. 9 refs

Effectiveness of Serious Games for Leap Motion on the Functionality of the Upper Limb in Parkinson’s Disease: A Feasibility Study

Directory of Open Access Journals (Sweden)

Edwin Daniel Oña

2018-01-01

Full Text Available The design and application of Serious Games (SG based on the Leap Motion sensor are presented as a tool to support the rehabilitation therapies for upper limbs. Initially, the design principles and their implementation are described, focusing on improving both unilateral and bilateral manual dexterity and coordination. The design of the games has been supervised by specialized therapists. To assess the therapeutic effectiveness of the proposed system, a protocol of trials with Parkinson’s patients has been defined. Evaluations of the physical condition of the participants in the study, at the beginning and at the end of the treatment, are carried out using standard tests. The specific measurements of each game give the therapist more detailed information about the patients’ evolution after finishing the planned protocol. The obtained results support the fact that the set of developed video games can be combined to define different therapy protocols and that the information obtained is richer than the one obtained through current clinical metrics, serving as method of motor function assessment.

NONE

1998-06-01

This Technical Standard (TS) does not contain any new requirements. Its purpose is to provide guides to good practice, update existing reference material, and discuss practical lessons learned relevant to the safe handling of plutonium. the technical rationale is given to allow US Department of Energy (DOE) health physicists to adapt the recommendations to similar situations throughout the DOE complex. Generally, DOE contractor health physicists will be responsible to implement radiation protection activities at DOE facilities and DOE health physicists will be responsible for oversight of those activities. This guidance is meant to be useful for both efforts. This TS replaces PNL-6534, Health Physics Manual of Good Practices for Plutonium Facilities, by providing more complete and current information and by emphasizing the situations that are typical of DOE`s current plutonium operations; safe storage, decontamination, and decommissioning (environmental restoration); and weapons disassembly.

The most intensely discussed and controversial issue in time keeping has been the proposal before the International Telecommunications Union (ITU) to redefine Coordinated Universal Time (UTC) so as to replace leap seconds by leap hours. Should this proposal be adopted, the practice of inserting leap seconds would cease after a specific date. Should the Earth's rotation continue to de-accelerate at its historical rate, the next discontinuity in UTC would be an hour inserted several centuries from now. Advocates of this proposal cite the need to synchronize satellite and other systems, such as GPS, Galileo, and GLONASS, which did not exist and were not envisioned when the current system was adopted. They note that leap second insertions can be and have been incorrectly implemented or accounted for. Such errors have to date had localized impact, but they could cause serious mishaps involving loss of life. For example, some GPS receivers have been known to fail simply because there was no leap second after a long enough interval, other GPS receivers failed because the leap second information was broadcast more than three months in advance, and some commercial software used for internet time-transfer Network Time Protocol (NTP) could either discard all data received after a leap second or interpret it as a frequency change. The ambiguity associated with the extra second could also disrupt financial accounting and certain forms of encryption. Those opposed to the proposal question the need for a change, and also point out the costs of adjusting to the proposed change and its inconvenience to amateur astronomers and others who rely upon astronomical calculations published in advance. Reports have been circulated that the cost of checking and correcting software to accommodate the new definition of UTC would be many millions of dollars for some systems. In October 2005 American Astronomical Society asked the ITU for a year's time to study the issue. This commission has

Conceptual design of a passively safe thorium breeder Pebble Bed Reactor

International Nuclear Information System (INIS)

Wols, F.J.; Kloosterman, J.L.; Lathouwers, D.; Hagen, T.H.J.J. van der

2015-01-01

Highlights: • This work proposes three possible designs for a thorium Pebble Bed Reactor. • A high-conversion PBR (CR > 0.96), passively safe and within practical constraints. • A thorium breeder PBR (220 cm core) in practical regime, but not passively safe. • A passively safe breeder, requiring higher fuel reprocessing and recycling rates. - Abstract: More sustainable nuclear power generation might be achieved by combining the passive safety and high temperature applications of the Pebble Bed Reactor (PBR) design with the resource availability and favourable waste characteristics of the thorium fuel cycle. It has already been known that breeding can be achieved with the thorium fuel cycle inside a Pebble Bed Reactor if reprocessing is performed. This is also demonstrated in this work for a cylindrical core with a central driver zone, with 3 g heavy metal pebbles for enhanced fission, surrounded by a breeder zone containing 30 g thorium pebbles, for enhanced conversion. The main question of the present work is whether it is also possible to combine passive safety and breeding, within a practical operating regime, inside a thorium Pebble Bed Reactor. Therefore, the influence of several fuel design, core design and operational parameters upon the conversion ratio and passive safety is evaluated. A Depressurized Loss of Forced Cooling (DLOFC) is considered the worst safety scenario that can occur within a PBR. So, the response to a DLOFC with and without scram is evaluated for several breeder PBR designs using a coupled DALTON/THERMIX code scheme. With scram it is purely a heat transfer problem (THERMIX) demonstrating the decay heat removal capability of the design. In case control rods cannot be inserted, the temperature feedback of the core should also be able to counterbalance the reactivity insertion by the decaying xenon without fuel temperatures exceeding 1600 °C. Results show that high conversion ratios (CR > 0.96) and passive safety can be combined in

Are we pharmacovigilant enough in ophthalmic practice?

Directory of Open Access Journals (Sweden)

Ashok Dubey

2013-01-01

Full Text Available No drug is absolutely safe. Pharmacovigilance is the science related to detection, assessment, understanding and prevention of adverse effects or any other possible drug-related problems. The ocular medications and devices can cause localized and systemic adverse effects. Not all adverse effects are known when a drug or device is launched in market because of limitations of clinical trials. Many adverse effects are recognized due to the spontaneous reporting of the vigilant doctors who observe and report such events encountered in their practice. Despite a large ophthalmic patient population base, India does not have robust adverse drug reaction (ADR database because of lack of reporting culture. Government of India recently launched the Pharmacovigilance Programme of India (PvPI to monitor ADRs and create awareness among the healthcare professionals about the importance of ADRs. Suspecting and reporting a possible drug reaction is very important in developing a safe and rational ophthalmic practice.

Probabilistic risk assessments show an inverse relationship between the likelihood and the consequences of nuclear and chemical plant accidents, but the Bhopal accident has change public complacency about the safety of chemical plants to such an extent that public confidence is now at the same low level as with nuclear plants. The nuclear industry's response was to strengthen its institutions and improve its technologies, but the public may not be convinced. One solution is to develop reactors which do not depend upon the active intervention of humans of electromechanical devices to deal with emergencies, but which have physical properties that limit the possible temperature and power of a reactor. The Process Inherent Ultimately Safe and the modular High-Temperature Gas-Cooled reactors are two possibilities. the chemical industry needs to develop its own inherently safe design precepts that incorporate smallness, safe processes, and hardening against sabotage. 5 references

The contract was an optional extension that was initiated on July 21, 1994 and that expired on May 31, 1995. The project manager was Thomas J. Nicholson, Office of Nuclear Regulatory Research. The objectives of this contract were to examine hypotheses and conceptual models concerning unsaturated flow and transport through fractured rock, and to design and execute confirmatory field and laboratory experiments to test these hypotheses and conceptual models at the Apache Leap Research Site near Superior, Arizona. The results discussed here are products of specific tasks that address a broad spectrum of issues related to flow and transport through fractures. Each chapter in this final report summarizes research related to a specific set of objectives and can be read and interpreted as a separate entity. The tasks include detection and characterization of historical rapid fluid flow through fractured rock and the relationship to perched water systems using environmental isotopic tracers of {sup 3}H and {sup 14}C, fluid- and rock-derived {sup 2343}U/{sup 238}U measurements, and geophysical data. The water balance in a small watershed at the ALRS demonstrates the methods of acounting for ET, and estimating the quantity of water available for infiltration through fracture networks. Grain density measurements were made for core-sized samples using a newly designed gas pycnometer. The distribution and magnitude of air permeability measurements have been measured in a three-dimensional setting; the subsequent geostatistical analysis is presented. Electronic versions of the data presented here are available from authors; more detailed discussions and analyses are available in technical publications referenced herein, or soon to appear in the professional literature.

In order to obtain the dispatching strategy that can better respond to changes in road conditions during the whole dispatching process, the real-time and time-dependent link travel speeds are fused, and a time-dependent polygonal-shaped link travel speed function is set up to simulate the predictable changes in road conditions. Response times, accident severity, and accident time windows are taken as key factors to build an emergency vehicle dispatching model integrating dynamic emergency vehicle routing and selection. For the unpredictable changes in road conditions caused by accidents, the dispatching strategy is adjusted based on the real-time link travel speed. In order to solve the dynamic emergency vehicle dispatching model, an improved shuffled frog leaping algorithm (ISFLA is proposed. The global search of the improved algorithm uses the probability model of estimation of distribution algorithm to avoid the partial optimal solution. Based on the Beijing expressway network, the efficacy of the model and the improved algorithm were tested from three aspects. The results have shown the following: (1 Compared with SFLA, the optimization performance of ISFLA is getting better and better with the increase of the number of decision variables. When the possible emergency vehicle selection strategies are 815, the objective function value of optimal selection strategies obtained by the base algorithm is 210.10% larger than that of ISFLA. (2 The prediction error of the travel speed affects the accuracy of the initial emergency vehicle dispatching. The prediction error of ±10 can basically meet the requirements of the initial dispatching. (3 The adjustment of emergency vehicle dispatching strategy can successfully bypassed road sections affected by accidents and shorten the response time.

This paper outlines a new durability model to assess the first inspection and maintenance period for structures. Practical scatter factor formulae are presented to determine the safe fatigue crack initiation and propagation lives from the results of a single full-scale test of a complete structure. New theoretical solutions are proposed to determine the s{sub a}-s{sub m}-N surfaces of fatigue crack initiation and propagation. Prediction techniques are then developed to establish the relationship equation between safe fatigue crack initiation and propagation lives with a specific reliability level using a two-stage fatigue damage cumulative rule. A new durability model incorporating safe life and damage tolerance design approaches is derived to assess the first inspection and maintenance period. Finally, the proposed models are applied to assess the first inspection and maintenance period of a fastening structure at the root of helicopter blade.

Verstappen, Jennie; Mirosa, Miranda; Thomson, Carla

2018-03-01

The number of individuals with food allergies or intolerances attending catered university residential colleges is increasing, and safe dining options are required to minimize the risk of allergic reactions and food-induced death. This qualitative research study sought to advance professional knowledge of the factors affecting allergen management practices, particularly pertaining to college foodservices. Three catered residential colleges affiliated with a major university in New Zealand were selected as research sites. The study used an ethnographic approach and systems-practice theory as a framework for data collection and organizing results. Data collection techniques included document analyses (3 hours per site), observations (6 to 8 hours per site), focus groups with foodservice workers (30 to 45 minutes per site, n=16), and interviews with foodservice managers (45 to 90 minutes per interview, n=5). Notes and transcripts were coded through the process of thematic analysis using NVivo for Mac software, version 11.1.1, to identify factors affecting allergen management practices. The main factors affecting allergen management practices at college foodservices included information provided by residents about dietary requirements; communication between residents and foodservice staff; systems for allergen management; attitude of foodservice staff; and college size. Detailed dietary information, effective communication with residents, sufficient resources, clarification of responsibilities, and thorough systems are required for staff to perform safe allergen management practices. Ultimately, successful implementation was predominantly determined by staff attitude. Foodservice managers are advised to identify motivators and address barriers of staff attitudes toward allergen management practices to promote successful implementation.

Full Text Available Tall buildings are becoming very popular around the world. Asia will have most of the tall buildings in this century. Both safety and sustainability aspects are important in planning and designing these buildings. The design and construction of tall buildings present many challenges for the design team, from engineers, architect through to the builder. Although structural systems could be developed and construction solutions could be found to design and construct very tall buildings in excess of 1 km (even 1 mile, other aspects such as fire and egress, long-term movements, environmental wind and perception of motion (including damping for dynamic effects, transportation (lifts issues, sustainability, durability and maintenance will govern and may even restrict the heights. Current practices and important issues related to design of safe and sustainable design of tall buildings are discussed in this paper.

Secrets of safe laparoscopic surgery: Anaesthetic and surgical considerations

Directory of Open Access Journals (Sweden)

Srivastava Arati

2010-01-01

Full Text Available In recent years, laparoscopic surgery has gained popularity in clinical practice. The key element in laparoscopic surgery is creation of pneumoperitoneum and carbon dioxide is commonly used for insufflation. This pneumoperitoneum perils the normal cardiopulmonary system to a considerable extent. Every laparoscopic surgeon should understand the consequences of pneumoperitoneum; so that its untoward effects can be averted. Pneumoperitoneum increases pressure on diaphragm, leading to its cephalic displacement and thereby decreasing venous return, which can be aggravated by the position of patient during surgery. There is no absolute contraindication of laparoscopic surgery, though we can anticipate some problems in conditions like obesity, pregnancy and previous abdominal surgery. This review discusses some aspects of the pathophysiology of carbon dioxide induced pneumoperitoneum, its consequences as well as strategies to counteract them. Also, we propose certain guidelines for safe laparoscopic surgery.

Dinner, Paul J.C.; Heimlich, Karel

2016-01-01

Around the world, a large number of aging nuclear plants are approaching final shutdown. While this is largely driven by plants reaching the end of their design life, economic factors such as low gas prices (in North America) and the smaller unit size of early commercial reactors are important contributors to this trend. In several instances, economic pressures have resulted in a need for a more rapid transition to Safe Enclosure than originally anticipated. Thus plans for this transition taking into account experience with Safe Enclosure periods of varying lengths are being actively prepared in many jurisdictions. The IAEA as well as other national and international authorities have long recognized the importance of the topic of Safe Enclosure and provided guidance, and the IAEA has recently undertaken a study of 'Lessons Learned from Deferred Decommissioning of Nuclear Facilities'. Beginning with preliminary experience from Canadian CANDU reactors in extended shutdown or safe enclosure, this paper aims to compare this experience with the larger pool of experience from the international community to: - classify the main issues or themes, - examine means to mitigate these, and - formulate general measures of 'good practice'. Compilation of this experience represents the first steps towards a comprehensive, searchable database potentially of use to many in the decommissioning community. Tabulation and analysis of the complete list (comprising approximately 70 cases) has provided the 'short list' of issues presented in Table 1. Examples of the most important listed issues are discussed. The authors' objective is to stimulate interest in extending this compilation. In this way it will continue to grow and benefit all those preparing for transition to decommissioning. (authors)

To establish the most effective approach and type of educational intervention for health professional students, to enable them to maintain a professionally safe online presence. This was a qualitative, multinational, multi-institutional, multiprofessional study. Practical considerations (availability of participants) led us to use a combination of focus groups and individual interviews, strengthening our findings by triangulating our method of data collection. The study gathered data from 57 nursing, medical and paramedical students across four sites in three countries (Aotearoa/New Zealand, Australia and Wales). A content analysis was conducted to clarify how and why students used Facebook and what strategies they thought might be useful to ensure professional usage. A series of emergent codes were examined and a thematic analysis undertaken from which key themes were crystallized. The results illuminated the ways in which students use social networking sites (SNS). The three key themes to emerge from the data analysis were negotiating identities, distancing and risks. Students expressed the wish to have material about professional safety on SNS taught to them by authoritative figures to explain "the rules" as well as by peers to assist with practicalities. Our interactive research method demonstrated the transformative capacity of the students working in groups. Our study supports the need for an educational intervention to assist health professional students to navigate SNS safely and in a manner appropriate to their future roles as health professionals. Because health professional students develop their professional identity throughout their training, we suggest that the most appropriate intervention incorporate small group interactive sessions from those in authority, and from peers, combined with group work that facilitates and enhances the students' development of a professional identity.

Fusco, Jesse C.; Swei, Sean S. M.; Nakamura, Robert H.

2015-01-01

This paper presents the development of sun safe controllers which are designed to keep the spacecraft power positive and thermally balanced in the event an anomaly is detected. Employed by NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE), the controllers utilize the measured sun vector and the spacecraft body rates for feedback control. To improve the accuracy of sun vector estimation, the least square minimization approach is applied to process the sensor data, which is proven to be effective and accurate. To validate the controllers, the LADEE spacecraft model engaging the sun safe mode was first simulated and then compared with the actual LADEE orbital fight data. The results demonstrated the applicability of the proposed sun safe controllers.

Safe Use of Contrast Media: What the Radiologist Needs to Know.

Beckett, Katrina R; Moriarity, Andrew K; Langer, Jessica M

2015-10-01

Iodinated and gadolinium-based contrast media are used on a daily basis in most radiology practices. These agents often are essential to providing accurate diagnoses, and are nearly always safe and effective when administered correctly. However, reactions to contrast media do occur and can be life threatening. Therefore, it is critical for faculty and staff to know how reactions to contrast agents manifest and how to treat them promptly. The decline in renal function seen occasionally after intravenous administration of iodinated contrast agents is poorly understood and likely multifactorial, and its association with the contrast medium may be overemphasized. However, it is important that radiologists be aware of current understanding and strategies to decrease the incidence of renal dysfunction. Nephrogenic systemic fibrosis, a skin disease, is an adverse reaction related to use of some gadolinium-based contrast agents in patients with chronic renal failure. The types of gadolinium most often associated with this condition and the indications for withholding gadolinium are important and are discussed in this article. The use of enteric contrast agents and contrast agents during pregnancy and nursing are reviewed briefly. Current knowledge for safe use of contrast media and key concepts that all radiologists should know are summarized in this review. © RSNA, 2015.

To explore attitudes to safe-induced abortion among pregnant women in Iran. In Islamic teachings, abortion is generally forbidden. However in specific circumstances, abortion may be permitted and currently, in Iran, the law allows termination of pregnancy only if three specialist physicians confirm that the pregnancy outcome may be harmful for the mother during pregnancy or after birth. Pilot, descriptive survey. A 15-item structured questionnaire focusing on attitudes to safe-induced abortion was developed and pilot tested. Participants were pregnant women who were referred to the Legal Medical Centre (July-December 2015) to obtain permission for abortion. On obtaining their informed consent, the women were asked to respond to each item if they agreed (Yes) or disagreed (No). Only their age, education, employment, marital status and religion were obtained. Of the 80 survey participants referred for a safe-induced abortion, 90% were carrying foetuses with a diagnosed congenital malformation and 10% were experiencing complications of pregnancy that endangered their health. The majority of women (85%) perceived abortion to be dangerous to health; 86% indicated that partners should be involved in decision-making about abortion, while 83% believed that public health officials should have complete control of abortion law. There is a need to improve women's and couples' awareness and practice of effective contraceptive methods. Further research is needed to better understand the complex issues that lead to unintended pregnancies and abortions considering religious beliefs and cultural and legal contexts. © 2017 John Wiley & Sons Ltd.

Design strategy for control of inherently safe reactors

International Nuclear Information System (INIS)

Chisholm, G.H.

1984-01-01

Reactor power plant safety is assured through a combination of engineered barriers to radiation release (e.g., reactor containment) in combination with active reactor safety systems to shut the reactor down and remove decay heat. While not specifically identified as safety systems, the control systems responsible for continuous operation of plant subsystems are the first line of defense for mitigating radiation releases and for plant protection. Inherently safe reactors take advantage of passive system features for decay-heat removal and reactor shutdown functions normally ascribed to active reactor safety systems. The advent of these reactors may permit restructuring of the present control system design strategy. This restructuring is based on the fact that authority for protection against unlikely accidents is, as much as practical, placed upon the passive features of the system instead of the traditional placement upon the PPS. Consequently, reactor control may be simplified, allowing the reliability of control systems to be improved and more easily defended

2016-09-01

Full Text Available Street food trading solves major social and economic problems in developing countries through the provision of ready-made meals at relatively inexpensive prices and employment for teeming rural and urban populace along its value chain. However, due to informal nature of the enterprise, the activities of the practitioners are not regulated. This gives ample room for unwholesome practices. The results are the risks such activities pose to the health and safety of practitioners along the value chain. This review paper, a summary of literature reports on risk factors in street food trade in developing countries and recommended safety intervention, is written with the hope of providing global baseline for intervention to ensure safe food practices. Adoption of safety approaches that permeates the entire chain of street food business from good agricultural practices through hazard analysis critical control points strategy to good hygiene practices by farmers, vendors and consumers would significantly reduce risks in street food consumption. Above all, active collaboration of all stakeholders toward the strengthening and proper enforcement of public health policies to ensure safe practices and engender safer and healthier society is recommended.

Is nuclear power safe enough

Andresen, A F [Institutt for Atomenergi, Kjeller (Norway)

1979-01-01

The lecture formed a commentary on the report of the Norwegian Government's Commission on Nuclear power Safety which was published in October 1978. It was introductorily pointed out that 'safe' and 'safety' are not in themselves meaningful terms and that the probability of an occurrence is the real measure. The main items in the Commission's report have been core meltdown, releases during reprocessing, waste disposal, plutonium diversion and environmental impacts. The 21 members of the Commission were unanimous in 7 of the 8 chapters. In chapter 2, 'Summary and Conclusions', 3 members dissented from the majority opinion, that, subject to certain conditions, nuclear power was a safe and acceptable source of energy.

A 'simple anterior fish excluder' (SAFE for mitigating penaeid-trawl bycatch.

Matthew J McHugh

Full Text Available Various plastic strips and sheets (termed 'simple anterior fish excluders'-SAFEs were positioned across the openings of penaeid trawls in attempts at reducing the unwanted bycatches of small teleosts. Initially, three SAFEs (a single wire without, and with small and large plastic panels were compared against a control (no SAFE on paired beam trawls. All SAFEs maintained targeted Metapenaeus macleayi catches, while the largest plastic SAFE significantly reduced total bycatch by 51% and the numbers of Pomatomus saltatrix, Mugil cephalus and Herklotsichthys castelnaui by up to 58%. A redesigned SAFE ('continuous plastic' was subsequently tested (against a control on paired otter trawls, significantly reducing total bycatch by 28% and P. saltatrix and H. castelnaui by up to 42%. The continuous-plastic SAFE also significantly reduced M. macleayi catches by ~7%, but this was explained by ~5% less wing-end spread, and could be simply negated through otter-board refinement. Further work is required to refine the tested SAFEs, and to quantify species-specific escape mechanisms. Nevertheless, the SAFE concept might represent an effective approach for improving penaeid-trawl selectivity.

Practice development using video-reflexive ethnography: promoting safe space(s towards the end of life in hospital

Directory of Open Access Journals (Sweden)

Aileen Collier

2016-05-01

Full Text Available Background: There is international consensus of the need for improved palliative and end-of-life care in hospital settings. What is less clear is how such improvements might be realised in practice. Research and practice improvement methodologies need to acknowledge the relational, spiritual, moral and ethical as well as physical dimensions of death and dying if improvements in care are to be achieved. Aims and objectives: The aim of this article is to explore the potential of video-reflexive ethnography as a practice development methodology to improve care of people with a life-limiting illness in the hospital setting. Methods: The study used video-reflexive ethnography and was underpinned by an indigenous research ethical framework. Findings: Study findings highlight the potential of video-reflexive ethnography as a practice development methodology. The reach of video extended internally and externally beyond immediate practice research sites to make hospital dying tangible. The research acted as a disruptive innovation, foregrounding peoples’ (patients and families expertise as well as that of healthcare workers. For some patient and family participants, the research offered a visual legacy. Conclusions: The theories underpinning video-reflexive ethnography and practice development are closely aligned; the former has potential as a practice development methodology to promote person-centred palliative and end-of-life care. The underpinning philosophical, ethical and values framework through which it is applied, along with the skills and aptitude of facilitation, are critical if its potential is to be realised. Implications for practice development: The delivery of person-centred end-of-life care may be facilitated by: Healthcare workers seeing themselves and those they care for differently Healthcare organisations seeing their employees as well as patients and families differently Researchers also being prepared to see themselves differently

Combined SAFE/SNAP approach to safeguards evaluation

International Nuclear Information System (INIS)

Engi, D.; Chapman, L.D.; Grant, F.H.; Polito, J.

1980-01-01

Generally, the scope of a safeguards evaluation model can efficiently address one of two issues, (1) global safeguards effectiveness, or (2) vulnerability analysis for individual scenarios. The Safeguards Automated Facility Evaluation (SAFE) focuses on (1) while the Safeguards Network Analysis Procedure (SNAP) is directed at (2). SAFE addresses (1) in that it considers the entire facility, i.e., the composite system of hardware and human components, in one global analysis. SNAP addresses (2) by providing a safeguards modeling symbology sufficiently flexible to represent quite complex scenarios from the standpoint of hardware interfaces while also accounting for a rich variety of human decision making. A combined SAFE/SNAP approach to the problem of safeguards evaluation is described and illustrated through an example

Full Text Available Blood transfusion is a life saving procedure in various transfusion-dependent life threatening conditions and donation of safe blood is a prerequisite for achieving this goal. This study was designed to evaluate the awareness regarding “safe blood” in Pakistani population. This study was conducted at a large scale through a population survey. The test population was divided into two groups i.e. general population and students. The Performa was designed for a general and student population and included 20 questions related to awareness of safe blood. A total of 4900 individuals belonging to different ethnic groups were included in this population survey. Results of social survey were analyzed by using Usman and Moin awareness chart. Results of this study revealed profound unawareness about safe blood in Pakistani population. This study found lack of awareness about safe blood as a major factor that is playing a vital role in the propagation of blood borne diseases in Pakistan. To secure the recipients from blood borne complications through blood donation, it is necessary to create effective awareness about safe blood in Pakistani population.
