The objective of this study was to characterize injuries occurring to crew members aboard a U.S. Navy ship. ⋯ Overuse musculoskeletal injuries occurred with the greatest incidence, but acute musculoskeletal injuries were responsible for the greatest morbidity. Soft tissue injuries occurred with an intermediate incidence but had the lowest overall morbidity. The safest place for crew members assigned to this Navy ship was aboard that ship at sea. Further studies of this nature could help guide medical efforts at injury treatment and prevention for shipboard personnel.

To evaluate an ambulatory physiological monitoring system during a mountaineering expedition. We hypothesized that the Environmental Symptoms Questionnaire, combined with frequent measurement of oxygen saturation and core temperature, would accurately identify cases of environmental illness. ⋯ Our monitoring system may complement, but cannot replace, on-site medical personnel during mountaineering expeditions.

The study examines personality characteristics that may increase vulnerability to sexual harassment among active duty Army personnel. A survey was administered to 1,060 male soldiers and 305 female soldiers at three Army posts located in the United States. ⋯ Two gender-related personality characteristics derived from the Extended Personal Attributes Questionnaire were hypothesized to increase vulnerability to sexual harassment. Negative Femininity, which reflects extreme passivity, and Negative Masculinity, which includes antisocial characteristics, were both found to be positively correlated with unwanted sexual experiences among male and female soldiers.

An investigation was conducted to determine if testing machine crosshead speed influenced shear bond strength (SBS) or the failure mode of composite bonded to enamel and dentin. Composite cylinders were bonded to 50 enamel and 50 dentin surfaces and thermocycled. Groups of 10 samples were debonded at speeds of 0.1, 0.5, 1.0, 5.0, and 10.0 mm/min. ⋯ No other differences in SBS were found. Samples tested at 0.5 mm/min demonstrated strikingly better cohesive vs. adhesive results than all other groups. SBS and cohesive vs. adhesive failures achieved with dentin bonding were significantly affected by crosshead speed.
