Physiological measurement of the push-pull effect during flight

The Push-pull In-flight Research Program was a Canadian Forces sponsored set of experiments conducted during flight to investigate the bodily responses to +gz exposure when preceded by low, or negative, gz exposure. This type of exposure is known as the push-pull manoeuvre. It has been hypothesized that the physiological responses of the human body to this manoeuvre can lessen an individual pilot\u27s g tolerance, thereby making him or her more susceptible to g-induced loss of consciousness. The overall aim of this thesis was to instrument an aircraft and perform in-flight research to collect data for evaluation of this hypothesis. As a joint research venture, the Aerospace Engineering Test Establishment, in conjunction with the Defence and Civil Institute of Environmental Medicine, performed a series of in-flight trials using a highly-instrumented CF-18 aircraft to gather physiological data on a wide spectrum of test subjects. The end-goal of this flight testing and follow-on research is to design a microprocessor controlled anti-g valve for future use in high-performance aircraft. This thesis evaluates the instrumentation approach, test procedures, and data gathering conducted during this test program. Preliminary results indicate the existence of a push-pull effect. Specific attention is given to the difficulties encountered with conducting experimental physiological research in an ejection seat equipped, high-performance fighter aircraft, and the methods and equipment developed to overcome these challenges

Helioseismic Mapping of the Magnetic Canopy in the Solar Chromosphere

We determine the three-dimensional topography of the magnetic canopy in and around active regions by mapping the propagation behavior of high-frequency acoustic waves in the solar chromosphere

A review of medical error taxonomies: a human factors perspective

Although a large number of medical error taxonomies have been published, there is little evidence to suggest that these taxonomies have been systematically compared. This paper describes a study comparing 26 medical error taxonomies using a human factors perspective. The taxonomies were examined to determine if they classified systemic factors of medical errors and if they utilized theoretical error concepts in their classifications. Scope of classification was also examined. It was found that two-thirds of the taxonomies classified systemic factors of medical errors and only a third utilized theoretical error concepts. Medical error taxonomies based on theoretical error concepts were more likely to be generic in applicability and also more likely to classify systemic factors and psychological error mechanisms of medical errors. In addition to terminology, the medical error taxonomies also varied in terms of domain-specificity, granularity, and developmental process. Different medical error taxonomies provide different information; how these differences affect medical error management needs to be investigated
