In modern conditions humans are exposed to the high level of stress that causes the gain in psychosomatic disorders. The problem of tolerance to increasing stress is becoming more and more urgent. The study of the possibilities of the dorsolateral prefrontal cortex stimulation, which affects the mechanisms of autonomic regulation, is of clinical interest.
 The aim of the study is to research the mechanisms of the resistance to increasing stress after transcranial magnetic stimulation of the dorsolateral prefrontal cortex of the right hemisphere in young males engaged in mental work. 
 Materials and methods. Thirty four healthy male 20 to 22 years students were observed. Transcranial magnetic stimulation of the dorsolateral prefrontal cortex projection at the F4 point in the electrode system marked “10–20” was carried out with an individually determined stimulus intensity in the amount of 300 stimuli with a frequency of 1 Hz. Autonomic effects were evaluated using spectral analysis of heart rate variability before and after stimulation. Seven-test was used as a stress test.
 Results. The predominance of oscillations in the low frequency of heart rate variability, indicating sympathetic activation, was determined in the examined young men, engaged in mental labour. After stimulation of the prefrontal cortex, there was an increase in heart rate variability, to a greater extent very low frequency oscillations associated with the central mechanisms of parasympathetic activity. During the stress test, the increase in adaptive capabilities was manifested by a less pronounced decrease in heart rate variability in comparison to the reaction before stimulation. A model of the effect of stimulation of the dorsolateral prefrontal cortex on heart rate variability was proposed.
 Limitations. The study is limited to the evaluation of spectral parameters of heart rate variability in 34 young healthy students before and after transcranial magnetic stimulation of the dorsolateral prefrontal cortex.
 Conclusion. Stimulation of the prefrontal cortex increased the adaptive capabilities of the body and can be used to increase stress resistance in people with intellectual work.","PeriodicalId":12550,"journal":{"name":"Gigiena i sanitariia","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135149512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the occupational factors having a harmful effect on the body of airport ground staff, noise dominates, the levels of which may exceed normative values. 
 The purpose of the study. To assess the acoustic loads on airport ground staff when working on the platform of a modern airport.
 Materials and methods. Noise measurements at the workplaces of airport ground staff of the profession “Duty “follow me” Driver” (hereinafter referred to as the Duty Driver) were carried out in accordance with GOST ISO 9612–2016. On the basis of the analysis of the working situation and the typical structure of the working day a measurement strategy based on the labour function was adopted. The CENTER 322 noise meter was used to measure the noise.
 Results. The basic duration of the Duty Driver’s working shift is 10.5 hours and the effective duration of the working day in the sector of the installation of the aircraft (AC) at the parking place (PP) is 4 hours. It is revealed that the greatest noise load on the Duty Officer occurs at the time of coordination of the AC on PP. The main and basic sources of noise in this case are the working turbines of the aircraft. The maximum sound pressure levels depended on the type of aircraft and ranged from 91.2 dBA for the Boeing-747 to 111.0 dBA for the AN-26. The equivalent sound pressure level for a 10.5-hour working day was 
 92.3 ± 3.4 dBA, for the effective duration of the working day (4 hours) – 96.5 ± 3.4 dBA. The maximum sound levels for most brands of modern aircraft do not exceed the standard parameters. Equivalent sound pressure levels exceed the established standards by 12.3–16.5 dBA.
 Limitations of the study. Since the Duty Driver was wearing a microphone on himself, there were uncertainties caused by the shielding and reflecting effects of the body.
 Conclusion. Duty Drivers are exposed to noise exceeding hygienic standards. This makes it possible to attribute the workplace of the Duty Officers to the harmful class of working conditions 3.2 according to the acoustic factor and makes it necessary for them to use personal protective equipment against noise when working on the platform.","PeriodicalId":12550,"journal":{"name":"Gigiena i sanitariia","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135149513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of new and modern methods of extracting metals from mineral ores in the metallurgical industry should be accompanied by an expert hygienic assessment of working conditions. 
 Materials and methods. The research was carried out at one of the metallurgical enterprises of the Murmansk region, which processes sulfide copper-nickel ores, produces electrolyte nickel, copper, cobalt, cobalt concentrate and precious metal concentrates. The characteristics of the air environment in the cobalt salt extraction department were carried out at the workplaces of hydrometallurgists based on the results of the analysis of fifty samples. Air samples were taken using individual samplers during 75.0% of the time of the work shift simultaneously at all three stages (sections) of cobalt salt extraction. The measurement of metals was performed by inductively coupled plasma atomic emission spectrometry.
 Results. Apparatchiks-hydrometallurgists body was estabished to be affected by a lot of harmful substances of complex composition, water-soluble and water-insoluble compounds of nickel and cobalt where the most significant. The content of water-soluble compounds of nickel and cobalt at all extraction sites of cobalt salts ranged from 0.0066–0.0236 mg/m3 and 0.0147–0.303 mg/m3, whereas water-insoluble – 0.0043–0.0150 mg/m3 and 0.002–0.0163 mg/ m3. The concentrations of copper, lead, cadmium compounds in the air of the working area did not exceed the MPC in all samples.
 Limitations. The study is limited of 50 air samples of the working areas of the metallurgical operators of the cobalt salt extraction department.
 Conclusion. Thus, modern methods of obtaining cobalt salts by extraction can pose a real threat to the health of workers in this production. The need to use correct models to assess and manage the risks of the harmful effects of water-soluble and water-insoluble metal compounds (nickel, cobalt) on human health requires the development of a special methodology for the implementation of hygienic regulation of their content in inhaled aerosol fractions of closed industrial premises.","PeriodicalId":12550,"journal":{"name":"Gigiena i sanitariia","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135148704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For an integral quantitative assessment of working population health it is reasonable to use “the chance of being healthy” indicator.
 Objective: The objective of the study is to establish regularities in age trends of “being healthy” chances among various occupational categories and jobs.
 Materials and methods. Three thousand two hundred forty three healthcare, industrial enterprise and education workers were surveyed. The assessment criterion is the absence of any chronic cardiovascular, respiratory, digestive, musculoskeletal, nervous, genitourinary and dermal system diseases. Chances of being healthy (ChH1) were calculated according to formula: ChH1 (%)= 100 • Ki /K, where: Ki is the number of people in i-age group, who have none of the above-mentioned chronic diseases, К is total number of persons examined in i-age group. Fatigue state duration, as “hours of fatigue per working week”, was used as a physiological equivalent of occupational load. Managing, psychological, hygienic, and non-occupational causes of fatigue and stress among workers were analyzed.
 Results. The age trend in chances of being healthy in workers employed in three various occupational fields was studied. Regression models “Chances of being healthy – age” were designed for doctors and nurses, working males and females, workers and experts, heads. A change of ChH1 in workers of different age groups, different workloads, and depending on managing, psychological, hygienic, and non-occupational factors was reported. 
 Limitations. The study is limited to considering two indicators, characterizing the chances of being healthy and four groups of fatigue and stress causes (managing, psychological, hygienic, and non-occupational) among workers of three fields of activity: healthcare, industry, and education.
 Conclusions. Three periods in the age trend of workers’ chances for being healthy, which differ in the level and rate of reducing chances: 20–39 years old, 
 40–69 y.o. and 70 and over y.o., are distinguished. The annual decrease of chances for being healthy is 1.17% in 25–45-aged healthcare workers, 1.19% in industrial workers, and 0.89% among university employees. The chances of being healthy depend on managing, psychological, hygienic, and non-occupational factors of fatigue and load.

In a subgroup of the patients with an initially low level of very low frequency oscillations (less than 30 ms2/Hz), a decrease in the non-linear entropy index (less than 180) was determined; when performing an active orthostatic test, the power of very low frequency spectrum oscillations in the patients of this subgroup decreased by more than 50% of the initial values. In all patients with vibration disease under orthostatic load, a decrease in the oscillations of high and low frequencies of the spectrum of heart rate variability was revealed, whereas in the control group, the low frequency oscillation power remained at the initial level. \u0000Limitations. The study was limited to the evaluation of spectral and non-linear indices of heart rate variability in 136 miners with vibration disease. \u0000Conclusion. The criteria for a severe course of autonomic neuropathy in the patients with vibration disease were identified: an initial decrease in the power of very low frequency oscillations and a non-linear entropy index of heart rate variability, as well as a decrease in the power of very low frequency oscillations by more than 50% during an orthostatic test. According to these criteria, in 40.4% of the miners with vibration disease, pronounced violations of the autonomic support with a lack of compensatory mechanisms of autonomic regulation were found to be detected.","PeriodicalId":12550,"journal":{"name":"Gigiena i sanitariia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70834804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
