BACKGROUND Although under-reported and understudied, unplanned extubations carry a significant risk of patient harm and even death. They are an important yardstick of quality control of care of intubated patients in the ICU. A unit-based risk assessment and multidisciplinary approach is required to decrease the incidence of unplanned extubations. METHODS As part of a quality-improvement initi...

Significant harm from heat has become a key restriction for deep metal mining with increasing depth. This paper proposes refrigeration ventilation system mines combined an existing air cycling and builds experimental platform six stope simulation boxes. Using the current method driving-resistance balance relationship, transfer flow constraints of were constructed. An artificial neural network w...

Enterprise resource planning (ERP) systems are becoming of increasing importance as integrated parts of business networks. They support ‘ebusiness implementation’ for better enterprise performance, ‘integrate activities’ for higher enterprise efficiency, and enjoy a ‘modular architecture’, for future extensions and further benefits. The aim of this review is to introduce ERP systems and explore...

Optimisation tools which determine the best layout for access and haulage in an underground mine address an important and difficult mine design problem. The complexity of the problem can be compared to the task of optimising the final pit design in an open pit, together with the pit haul roads required. The strategic design of an underground mine layout must address the location of haulage shaf...

One of the most frequent complications associated with endotracheal intubation itself in intensive care units is unplanned extubation, which represents a potentially serious complication given that many patients may need reintubation while in poor condition. This scenario may account for an increase in morbidity and even in mortality. To be able to compare the rates of unplanned extubation in c...

BACKGROUND The goal of our work was to develop a simple method to evaluate a compensation treatment after unplanned treatment interruptions with respect to their tumour- and normal tissue effect. METHODS We developed a software tool in java programming language based on existing recommendations to compensate for treatment interruptions. In order to express and visualize the deviations from th...

CONTEXT Several studies have found a relationship between abortion and prior substance use, suggesting that a reduction in substance use might help decrease abortion rates. However, such a conclusion requires a greater understanding of the processes linking abortion and prior substance use. METHOD Path analysis of longitudinal data from 1,224 women was used to simultaneously test two pathways...

We sought to identify how gynecologic oncologists approach reproductive counseling for their fertile, reproductive age patients, and their experience with unplanned pregnancies. Members of the Society of Gynecologic Oncology (SGO) were surveyed electronically regarding consistency of counseling patterns of contraception and fertility concerns, most and least common contraceptive methods utilize...
