During the course of the voyage, divers experience the effect of the wide range of adverse factors of operator labor and ship's habitability.The objective of the study is to estimate the state of cardiovascular system of operators of deep water technical means after using the complex of measures aimed at correction of function al state of operators during the course of the voyage.Materials and methods. The study was conducted with the participation of 38 operators of deep water technical means from among the crew of nuclear submarine engaged in operator labor activity. The study was performed twice: before the voyage and after return to base and included: cardiorhythmogram and psychophysiological study methodologies of functional state. Patients were divided into two groups: main (n = 13) and control (n = 25).Results and discussion. The control group shows sympathicotonia (reducing heart rate variability, intensity of respiratory arrhythmia). The main group, on the contrary, shows relative balance of regulatory systems. Thus, the conducted assessment of the state of cardiovascular system showed positive effects of using the complex of measures aimed at correction of functional state of operators during the course of the voyage.
The article provides an analysis of regulatory and technical documents and reference data that determine the nomenclature of anthropometric indicators for various professional categories of personnel. It is shown that the anthropological indicators given in these sources have lost their relevance due to the acceleration of the planet’s population over the past decades, as well as the absence of a whole group of necessary characteristics for the design of marine equipment. So in the standards of the 1980s, the average value of a person’s height for the 95th percentile is 183 cm, and in the European standards of 2000, the height of a man for the 95th percentile is 188.1 cm. The role of dynamic anthropometric characteristics in the justification of ergonomic requirements for control systems is shown. The basic static and dynamic anthropometric indicators necessary for the design of promising marine equipment are determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
