Using the prediction of cancer outcome as a model, we have tested the hypothesis that through analysing routinely collected digital data contained in an electronic administrative record (EAR), using machine-learning techniques, we could enhance conventional methods in predicting clinical outcomes.

This work represents field measurements of task completion times for the crew of an M198 Howitzer. The M198 is a towed, 155mm artillery piece, manned by a 10-member US Marine crew for the exercise. Baseline times in battle dress uniform and degraded times in full nuclear and chemical protective gear (MOPP4) are included. Times are reported for 22 tasks composing a fire mission. Task performance is defined as the ratio of baseline task completion time to completion time with crewmembers in MOPP4. A regression of performance versus time in MOPP4 separates the performance degradation caused by the encumbrance of the MOPP gear from that caused by accumulating heat strain. Meteorological data and physiological data from the exercise are included in the report. 12 of 22 M198 tasks show significant degradation from encumbrance effects. 10 of 22 tasks show significant degradation with time in MOPP4. Degradation is correlated with demand ratings on human abilities of the tasks and with the number of crewmembers involved in a task. The measurements and analyses are part of an ongoing effort of DNA's NBC Consequence Assessment Program to support quantification of military performance degradation in an NBC environment., Prepared in cooperation with ARES Corp., Arlington, VA. Included with AD-M000 642. See also AD-A286 891

This work represents field measurements of performance times for the crew of an M198 howitzer. The M198 is a towed, 155mm artillery piece, manned by a 10-member US Marine crew for this exercise. Baseline times in battle dress uniform and degraded times in full nuclear and chemical protective gear (MOPP4) are included. Reported times consist of emplacement time, displacement time, time to first round (TTFR), and time between rounds (TBR) for three fire mission types. Baseline times for TTFR and TBR show a decrease (improvement) with repetition number during a day's fire missions, indicating a significant practice or warm-up effect. Times for TTFR and TBR show a significant increase (degradation) when the crew is at MOPP4. The performance degradation worsens with mission repetition (increasing time-in-MOPP4). These measurements are part of the ongoing effort of DNA's Radiation Risk/Safety program to support quantification of military performance degradation in an NBC environment., Sponsored in part by contract DNA001-90-C-0164. Prepared in cooperation with ARES Corp., Arlington, VA.
