The Impact

Using questionnaires, administrative claims, and chart review data, the current study explored the impact of using an electronic medical record system to administer, score, and store the Pediatric Symptom Checklist (PSC-17) during annual pediatric well-child visits. Within a sample of 1773 Medicaid-insured outpatients, the electronic system demonstrated that 90.5% of cases completed a PSC-17 screen electronically, billing codes indicating a screen was administered agreed with the existence of a questionnaire in the chart in 98.8% of cases, the classification of risk based on PSC-17 scores agreed with the classification of risk based on the Current Procedural Terminology code modifiers in 72.9% of cases, and 90.0% of clinicians’ progress notes mentioned PSC-17 score in treatment planning. Using an electronic approach to psychosocial screening in pediatrics facilitated the use of screening information gathered during the clinical visit and allowed for enhanced tracking of outcomes and quality monitoring.

And Control

Epidemiologic inquiry, collation of data and statistical calculations are useful in identifying the place foods were mishandled or mistreated and the probable vehicle of foodborne disease. Biases during collection of information and classification of cases and control can lead to false conclusions. Laboratory analyses can confirm the etiologic agent and vehicle if an appropriate sample is collected, and sometimes trace the source of the etiologic agent. Laboratory analyses may give negative or misleading results depending on the samples collected and the quantity of samples collected. Hazard analyses are necessary to determine the mode of contamination, the means by which the pathogen survived processing, and the conditions that allowed the pathogenic bacteria to increase to populations or elaborate toxins sufficient to cause the illness. Hazard analysis is the link between epidemiology and microbiology that identifies events that contributed to the causation of outbreaks and, hence, provides information upon which to initiate control actions and to base preventive measures.

Objective: to assess the demand for Intensive Care Unit beds as well as the classification of the patients for admission, according to the priority system. Method: a retrospective and cross-sectional study, developed from January2014 to December2018 in two Intensive Care Units for adults of a university hospital. The sample consisted of the requests for vacancies according to the priority system(scale from 1 to 4, where 1 is the highest priority and 4 is no priority), registered in the institution’s electronic system. Results: a total of 8,483 vacancies were requested, of which 4,389(51.7%) were from unitB. The highest percentage in unitA was of Priority2 patients(32.6%); and Priority1 was prevalent in unitB(45.4%). The median lead time between request and admission to unitA presented a lower value for priority1 patients(2h57) and a higher value for priority4 patients(11h24); in unitB, priority4 patients presented shorter time(5h54) and priority3 had longer time(11h54). 40.5% of the requests made to unitA and 48.5% of those made to unitB were fulfilled, with 50.7% and 48.5% of these patients being discharged from the units, respectively. Conclusion: it is concluded that the demand for intensive care beds was greater than their availability. Most of the patients assisted were priorities1 and2, although a considerable percentage of those classified as priorities3 and4 is observed.

In Russian practice, at the author of the mines of the revolution, equipment was used, which was well made at the pest of domestic factories. In view of the core bankruptcy of the domestic factories, the coat of arms of the miners were forced to carry the burden and had the choice to buy foreign equipment.. In 90-ies tax on trail equipment, which was not produced in Russian boards, was not collected at all. The miners bought the equipment abroad, without any additional problems for the equipment import did not arise. Powered roof support and shearers are not produced in Russia and the plants had to buy them abroad both the avalanche and the separate equipment. The term fund "complex" pest has a conditional blue character, the conclusion reflecting taking only the stage of the kinematic announcement of the connection, the input of the electrohydraulic and if the electronic system suddenly controls interchangeable author sets of equipment address. temperament It is advisable to revise the concept of more classification of the kiln cleaning mechanized complexes and the lighthouse to adjust the core of the customs due to legislation to address some of the tinder customs duties on the author of the mining equipment.

The safety of NPPs has to be maintained in any condition which has to be considered. Rational criteria are especially needed for adequate classification of external hazards. Characteristics of external hazards, e.g. Tsunami, Earthquake, Land slide etc, are changed by features of the site. It is necessary to make a rational and clear process of classification to appropriate method of risk assessment. This study treated of various external hazards included natural phenomena and man-made events. Much disaster information was gathered from historical documents these one thousand and five hundred years (1). Published standards of US and IAEA were referred. This study provided some viewpoints for classification, e.g. hazard frequency, range of impact, basic design, and difficulty of accident management etc. The classification included several paths; a full-scope PRA, a hazard analysis, or a comparison between an impact of the hazard and the design condition against it.

AbstractThe process of developing civil aircraft and their related systems includes multiple phases of Preliminary Safety Assessment (PSA). An objective of PSA is to link the classification of failure conditions and effects (produced in the functional hazard analysis phases) to appropriate safety requirements for elements in the aircraft architecture. A complete and correct preliminary safety assessment phase avoids potentially costly revisions to the design late in the design process. Hence, automated ways to support PSA are an important challenge in modern aircraft design. A modern approach to conducting PSAs is via the use of abstract propagation models, that are basically hyper-graphs where arcs model the dependency among components, e.g. how the degradation of one component may lead to the degraded or failed operation of another. Such models are used for computing failure propagations: the fault of a component may have multiple ramifications within the system, causing the malfunction of several interconnected components. A central aspect of this problem is that of identifying the minimal fault combinations, also referred to as minimal cut sets, that cause overall failures.In this paper we propose an expressive framework to model failure propagation, catering for multiple levels of degradation as well as cyclic and nondeterministic dependencies. We define a formal sequential semantics, and present an efficient SMT-based method for the analysis of failure propagation, able to enumerate cut sets that are minimal with respect to the order between levels of degradation. In contrast with the state of the art, the proposed approach is provably more expressive, and dramatically outperforms other systems when a comparison is possible.

The ITER Vacuum Vessel (VV) is a nuclear pressure equipment according to the French Order of December 12th 2005. Therefore the VV manufacturer (the ITER Organization) must demonstrate that the applicable essential safety requirements and radioprotection requirements are satisfied. The paper describes several aspects requiring particular attention from the start in order to assure that the VV will finally comply with the legal requirements. - definition of responsibilities; - fixation of the design; - hazard analysis and uncertainties; - in-service inspection requirements; - classification of all VV parts; - material specifications; - structural strength evaluation; - fabrication tolerances; - assessment of the RCC-MR Code; - alternatives to meet the ESR and RPR. It’s important that all participants to the project have a good understanding of the applicable legislation and are aware of the impact of their decisions on the final conformity of the VV with the essential safety requirements and radioprotection requirements.
