#1
Robert J Ruben
The existence of the adenoid first appears to have been noted by Conrad Victor Schneider in 1661. James Yearsley reported in 1842 one case in which he improved hearing by removal of a mucus membrane from behind the uvula, which indicates some appreciation of a relationship of the nasopharynx to ear disease. Hans Wilhelm Meyer, in 1868, was the first to demonstrate the relationship of the adenoid to ear disease and to develop an effective, although somewhat difficult, surgical operation to remove the adenoid...

BACKGROUND: Keratoconus is a progressive noninflammatory ectatic corneal dystrophy, characterized by corneal thinning and increased curvature with central or paracentral tapered protrusion. Such changes in corneal morphology induce irregular astigmatism and myopia, resulting in visual acuity impairment. This report assesses cases in which keratoconus is not an absolute disabling condition for civil aviation pilots. METHODS: Six cases of keratoconus in active pilots are presented...

Healthcare has enthusiastically embraced quality and safety improvement. Yet, more radical transformation is clearly needed to make a more significant impact on error reduction and to ensure consistent quality. This need for transformation is leading healthcare to examine how other industries, such as nuclear power and aviation, improve safety to achieve a high degree of reliability and avoid potential catastrophes. Research has shown that successful organizations in high-risk industries achieve high reliability by maintaining a cultural mindfulness that allows them to continually reinvent themselves in complex environments...

To develop and validate a classification of non-technical skills (NTS) in military aviation, a study was conducted, using data from real operations of F16 aircraft formations. Phase 1 developed a NTS classification based on the literature review (e.g. NOTECHS) and a workshop with pilots. The Non-TEChnical-MILitary-Skills (NOTEMILS) scheme was tested in Phase 2 in a series of Principal Component Analysis with data from After-Action-Review sessions (i.e. 900 records from a wide range of operations). The NTS were found to make a good prediction of Mission Essential Components (R(2) > 0...

Marisa Aguiar, Alan Stolzer, Douglas D Boyd
BACKGROUND: Flying over mountainous and/or high elevation terrain is challenging due to rapidly changeable visibility, gusty/rotor winds and downdrafts and the necessity of terrain avoidance. Herein, general aviation accident rates and mishap cause/factors were determined (2001-2014) for a geographical region characterized by such terrain. METHODS: Accidents in single piston engine-powered aircraft for states west of the US continental divide characterized by mountainous terrain and/or high elevation (MEHET) were identified from the NTSB database...

Alexis Carrel and Charles Lindbergh were among the most famous international figures in the 20th century: Carrel, the surgeon-scientist who won a Nobel prize as a young surgeon, and Lindbergh, the aviator-engineer who pioneered aviation and promoted commercial flight throughout his life. Surprisingly, these two amazing individuals came together to collaborate on the early development of extracorporeal circulation. Their work was interrupted by the onset of World War II, which destroyed one of them and nearly destroyed the other...

INTRODUCTION: Education frequently dictates students need to study for prolonged periods of time to adequately prepare for examinations. This is especially true with aviation preflight indoctrination (API) candidates who have to assimilate large volumes of information in a limited amount of time during API training. The purpose of this study was to assess caffeine consumption patterns (frequency, type, and volume) among naval aviation candidates attending API to determine the most frequently consumed caffeinated beverage and to examine if the consumption of a nonenergy drink caffeinated beverage was related to energy drink consumption...

P R Greig, H E Higham, J L Darbyshire, C Vincent
Background: The variability in risk tolerance in medicine is not well understood. Parallels are often drawn between aviation and anaesthesia. The aviation industry is perceived as culturally risk averse, and part of preflight checks involves a decision on whether the flight can operate. This is sometimes termed a go/no-go decision. This questionnaire study was undertaken to explore the equivalent go/no-go decision in anaesthesia. We presented anaesthetists with a range of situations in which additional risk might be expected and asked them to decide whether they would proceed with the case...

This study aims to develop a taxonomy of coordination behaviors during emergencies in nuclear power plants (NPPs). We summarized basic coordination behaviors from literature in aviation, healthcare, and nuclear field and identified coordination behaviors specific to the nuclear domain by interviewing and surveying control crew operators. The established taxonomy includes seven workflow stages and 24 basic coordination behaviors. To evaluate the reliability and feasibility of the taxonomy, we analyzed 12 videos of operators' training sessions by coding coordination behaviors with the taxonomy and the inter-rater reliability was acceptable...

Although Arabic numerals (like '2016' and '3.14') are ubiquitous, we show that in interactive computer applications they are often misleading and surprisingly unreliable. We introduce interactive numerals as a new concept and show, like Roman numerals and Arabic numerals, interactive numerals introduce another way of using and thinking about numbers. Properly understanding interactive numerals is essential for all computer applications that involve numerical data entered by users, including finance, medicine, aviation and science...

Crew resource management (CRM) describes a system developed in the late 1970s in response to a series of deadly commercial aviation crashes. This system has been universally adopted in commercial and military aviation and is now an integral part of aviation culture. CRM is an error mitigation strategy developed to reduce human error in situations in which teams operate in complex, high-stakes environments. Over time, the principles of this system have been applied and utilized in other environments, particularly in medical areas dealing with high-stakes outcomes requiring optimal teamwork and communication...

Aviation transportation systems have developed rapidly in recent years and have become a focus for research on the modeling of epidemics. However, despite the number of studies on aggregated topological structures and their effects on the spread of disease, the temporal sequence of flights that connect different airports have not been examined. In this study, to analyze the temporal pattern of the Chinese Aviation Network (CAN), we obtain a time series of topological statistics through sliding the temporal CAN with an hourly time window...
