EEG changes measured by spectrum analysis under hyperbaric conditions.

The EEG activity was followed during simulated diving to 20 m depth. Altogether 49 EEG records of 5 min length were taken in 5 divers breathing compressed air in a close system. No significant changes of the EEG could be found during either compression or decompression if only conventional indicators, such as the amplitude of theta activity, were tested.

Evaluation of psychic parameters in seamen and fishermen with a long employment period. Part I.

The aim of the present study was to select these personality features of seafarers with a long employment period, which affect the process of occupational adaptation. A group of 588 seamen of deck, catering and engine crew--including fishermen from the fish processing plant, mean age 44,89 years and the mean period of employment at sea 19,42 years, was subjected to MMPI test. The highest number of results deviating from the norm were found in the group of engine crew.
