A study of decision-making behavior of aircraft pilots deviating from a planned flight.
This paper outlines an investigation into the worth structures of pilots facing a deviation from a planned flight. A "paper and pencil" simulation was used to frame the situation into which pilots interjected their own decision-making skills in a simple ranking of candidate diversion airports with varying locational, navigational aid, radar, and weather attributes. ⋯ Systematic differences in the worth functions of the pilots were not found as a result of dividing the pilot sample according to any measure of flight hours' experience. However, differences were found when the pilot sample was grouped according to grade of pilot certificate, type of pilot training, and type of flying most commonly done.

Comparative StudyA study of treadmill exercise protocols for Chinese males.
Treadmill stress testing currently is used in screening for coronary artery disease. Maximal oxygen consumption is the best index of work capacity and maximal cardiovascular function. Clinically, there are many exercise protocols being utilized, including Bruce, Kattus, Balke, Naughton, and Chinese Air Force (CAF). ⋯ The regression equation of oxygen consumption and duration was: Y (ml/kg/min) = 1.26X (min) + 26.3. The CAF protocol is a safe, reproducible, easily performed method with moderate exercise duration. We confirm its advantages and prefer to select this protocol to serve as a routine screening or clinical method for use in testing Chinese people.

Case ReportsThe transportable recompression rescue chamber as an alternative to delayed treatment in serious diving accidents.
This report summarizes experience in the use of a Transportable Recompression Rescue Chamber (TRRC) for one man in the rapid initiation of treatment and evacuation in severe scuba diving accidents. An evacuation system is described which incorporates the centralized management of all diving accidents and standardized TRRCs capable of interlocking under pressure with the stationary medical chamber. Oxygen breathing capability in the TRRC allows the use of up-to-date U. ⋯ No complications associated with the use of TRRCs have been encountered. Ideally, evacuation should be made in a pressurized two-compartment (for a victim and an attendant) chamber. However, if this is not available we strongly advocate the use of one-man pressurized TRRCs over unpressurized evacuation.

Comparative StudyLong-term follow-up of Skylab bone demineralization.
The os calcis mineral was measured in the nine Skylab crew members and in eight control subjects, 5 years after the Skylab Program, utilizing a photon absorptiometric technique. These measurements were compared with preflight measurements in an attempt to discover any long-term effects of space flight on the skeletal system. A statistically significant loss of bone mineral was found in the crew members who flew, but caution is urged in the interpretation of this difference. A recommendation to continue studies of this type is made.

In the 12 month period Oct. 1, 1978 - Sept. 30, 1979, United States airlines carried 318 million passengers as revealed by the Federal Aviation Administration. It is estimated that 1 out of every 1 million passengers may be deplaned by an unscheduled landing due to a life-threatening medical emergency. ⋯ This paper provides information on in-flight emergencies and describes some simple ane effective techniques suitable for in-flight operations. Training flight attendants to deal with in-flight medical emergencies and to use first-aid support equipment and essential and useful drugs may later help with stabilization of a victim and allow continuing the flight to the scheduled destination, obviating the need for a diverted landing with all of the associated potential flight hazards, inconveniences, fuel wastage and increased costs.
