background and aims: cardiac surgery patients are at high risk of pressure ulcers. in the present study, we determined the incidence of pressure ulcer in patients who were admitted to open heart cardiac surgery intensive care unit and related risk factors. methods: with using convenience sampling all the eligible patients who were admitted to boali cardiac surgery during june to august 2015 wer...

We propose a novel signal model, based on sparse representations, that captures cross-scale features for visual signals. We show that cross-scale predictive model enables faster solutions to sparse approximation problems. This is achieved by first solving the sparse approximation problem for the downsampled signal and using the support of the solution to constrain the support at the original re...

INTRODUCTION This study explores predictive factors in safety culture. METHOD In 2008, a sample 939 employees was drawn from 22 departments of a telecoms firm in five regions in central Taiwan. The sample completed a questionnaire containing four scales: the employer safety leadership scale, the operations manager safety leadership scale, the safety professional safety leadership scale, and t...

The theory of scale relativity suggests that, at very large time scales, classical laws should be replaced by a non-deterministic, quantum-like description. The theory gives up individual, localized trajectories, but it yields the probability density of families of virtual trajectories, as deduced from a generalized Schr6dinger equation. In this paper, we compare the system of three planets rec...

introduction: stroke is recognized as the third cause of mortality after cardiovascular and cancer diseases, so that lead to death of about 5 million people, annually. there are several scales to early prediction of at risk patients and decreasing the rate of mortality by transferring them to the stroke center. in the present study, the accuracy of cincinnati pre-hospital stroke scale was asses...
