[Urgency of comparative spectral analysis of noises in sanitary inspection].

Spectrum (presentation, an image) is a set of all values of any that characterizes, for example, sound-wave propagation. In exact sciences, the expansion of oscillatory function in terms of harmonics, by calculating the Fourier coefficients denotes a spectral analysis. The paper discusses how to further improve the existing sanitary document regulating the order of noise measurement in the area of an apartment block and in residential and public buildings. The author proposes to supplement the document with a procedure for the comparative analysis of the spectral contents of noises.

[On methods for unambiguous assessment of occupational environmental factors in occupational medicine]. / K metodike formirovaniia odnoznachnykh otsenkok pokazatelei faktorov proizvodstvennoi sredy v gigiene truda.

Suggested system to formalize hygienic information is designed for definite and unambiguous assessment of varied totality of occupational environmental parameters in specific object of sanitary supervision; for study and analysis of physiologic, hygienic and clinical dependencies of workers' health state on the work conditions; for further specification of scientifically based prophylactic measures and social economic protection of workers.

[Forecasting harmless service and work safety for able-bodied population]. / O prognoze bezvrednogo stazha i okhrane zdorov'ia trudnosposobnogo naseleniia.

The authors suggest medical and mathematical simulator for forecasting hygienically harmless length of service with consideration of occupational load and other circumstances causing human wear and ageing. Forecasting length of individual occupational longevity is a way to novel system of work safety and health preservation for able-bodied population.

[Summarizing experience concerning certification of workplaces based on work conditions]. / Nekotorye obobshcheniia opyta organizatsii attestatsii rabochikh mest po usloviiam truda.

The article contains theoretic principles derived from the author's practice of working environment assessing. The author suggests and justifies definition for the assessing procedure, necessitates improvement and updating of current leading documents. Important notion is that development of governmental function--regulation of work safety--that is new for Russia, but common for developed countries, forms a first step--organization of governmental institution. The author necessitates scientific, ergonomic and hygienic basis for further development of monitoring system for work safety.

["Even", integral indicators in systemic mathematical analysis of fatigue]. / "Odnorodnye", integral'nye pokazateli v sistemnom, matematicheskom analize utomleniia.

The article considers 3 different points of view on systemic mathematical analysis of human fatigue process. In this case, the same physiologic information is processed according to various algorithms for integral and digital estimates of lowered performance and energy expenditure, as well as indirect characteristics of inhibition and excitation processes in the brain cortex. The mathematical results are applied in computer forecasting of individual occupational risk at the specific workplace.

[Again about occupational diseases]. / Snova o proizvodstvenno-obuslavaennykh zabolevaniiakh.

The article deals with a new physiologic and hygienic approach to evaluation of risk factors for occupational diseases and proves their occurrence even in individuals who have no exposure to critical and intensive work conditions causing occupational diseases.

[Systematic mathematical modeling of functional tension in a working man]. / O sistemnom matematicheskom modelirovanii zavisimostei funktsionalnogo napriazheniia rabotaiushchego cheloveka.

A bipolar pattern of human work was applied to evaluate the dependences of human functional status and capacity for work on occupational factors, work algorithms, etc. The results lead to a conclusion that the relationships of intellectual and physical elements of work have a special influence on the correlations between functional status and three main structures of the pattern: industrial conditions, working process and other acting circumstances (from emotions to social and everyday life). The pattern enables to base automatic controlling systems taking into account the complete human functioning, to make a durable forecast of human health and capacity for work, which is very important for medical insurance.
