Introduction. In increased requirements to occupational and personal qualities of workers engaged into or applying for dangerous professions, effi ciency of occupational selection considerably depends on choice of methodic approaches adequate to the study objectives. Objective. To study psychophysiologic approaches to evaluation of social psychologic reliability and occupational fi tness of individuals with dangerous professions, for revealing prognostic facilities of new methods and for improving occupational selection for military and police offi cers. Materials and methods. Psychophysiologic studies used eye-tracker SMI-RED–250 and polygraph “Diana” and covered 201 candidates for service in various divisions of RF Investigating Committ ee. Major part of the examinees consisted of individuals aged under 30 years (134 males and 67 females). All the candidates had normal vision or corrected to normal one. Evoked brain potentials study covered 114 candidates for military service (2 females and 112 males) aged 17 to 52 years. According to polygraph study, 51.8% of the examinees demonstrated a risk factor of “drug use”. Results. Th e authors presented results of psychophysiologic studies of occupational fi tness in candidates for military and police service. Nowadays, polygraph study remains a reliable method to reveal reactions proving presence of concealed information. Using evoked brain potentials for disclosing individuals who conceal drug usage is an important procedure in security maintenance. Within a standard polygraph procedure, videooculography (eye-tracker) seems the most interesting. Th e studies covered possible use of evoked EEG potentials and eye-tracker along with polygraph study for personnel checkups. Conclusions. Occupational selection in individuals with dangerous professions obtained experimental data indicating high effi ciency of combined use of eye-tracking and polygraph, for diagnosis of social psychologic reliability one can use soft ware of evoked brain potentials with demonstration of drugs-associated slides.
An analysis of the literature and an essay on the problem of recognizing the diseases of workers — diagnosis and causation(work-relatedness assessment) are given. A historical reference is made on the etiology of workers’ diseases and the statements of the classics about the causality in medicine. The main categories of occupational medicine and terminology of the WHO and ILO, the principles of evidence in occupational health are considered. The WHO concept of work-related diseases (WRD), occupational disease (OD) recognition systems under ILO Convention No. 121, features of the ILO occupational diseases list (revision 2010), and the criteria for inclusion of diseases in this list are presented.The general provisions of causation, types of causation algorithms in consensus and evidence-based medicine, as well as a generalized algorithm for analyzing periodic medical examinations data are considered. The European experience of recognition of WRD is considered. Based on experience and literature data, we propose a 10-step causation algorithm, including forecasting the probability of OD and WRD, as well as quantifying the degree of work-relatedness with computer support programs from the electronic directory «Occupational Risk» (http://medtrud. com/). It is concluded that legal recognition of WRD is needed for early diagnosis and prophylaxis of workers’ health disorders in conditions of digitalization of the economy and society.
The article discusses the issues of adjustment, developed in 2007 and supplemented in 2009, of the methodology for evaluating the equivalent level of cabin noise of civil aviation aircraft in Russia. The relevance of the problem is due to high levels of professional hearing loss among the aircrew members of the air force, which is directly related to the lack of unified and competent approaches to assessing the acoustic load on the hearing organ of the aircrew members. The updated methodology contains full-fledged data on noise levels in modern domestic and foreign airliners, data on certification of acoustic efficiency of aircraft accessories, a direct algorithm and formulas for calculating the noise load for the selected periods of flight operation.
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.
