Aim – Evaluate the influence of work environment on the risk of arterial hypertension (AH) development in employees of various social groups. Material and Methods – 3664 employees of Siberian industrial enterprises and office workers were examined. Apart from occupation AH predictors were considered to be gender, age, Quetlet index, smoking, alcohol abuse, marital status and education. Classification trees were used as a method of predicting AH presence or absence. Results – A classification tree allowing 75% prediction of AH presence/ absence was obtained. Quetlet index (100), age (83) and occupation (63) were maximum significant predictors for classification. A structure of the classification tree changed in different age groups and; moreover, with similar prediction level the predictor significance differed greatly. In middle-aged population occupation along with Quetlet index was characterized by higher significance (89) while in elderly subjects the significance of occupation decreased (55) and the significance of education and marital status rose (60 and 34, respectively). Different AH prevalence was observed in the occupational groups with similar working conditions. Conclusion – Quetlet index, age and occupation are highly significant for AH prediction in working age population. Occupation is very significant for AH prediction in middle-aged patients. Other factors under study do not usually influence AH development much, though, with ageing their role gets more important.

This paper focuses on mathematical models of distribution channels in the multi-mesh-networks, the 802.11 standard by which the balancing of mesh-stations on domains conflicts with their territorial remoteness and activity that can improve the performance of multichannel mesh network as a whole.

In this paper, an approach to the multitensor description of telecommunication network attending for a great amount of user traffics being transmitted between the multitude of network units is considered. In order to provide the multiple-aspect description of the telecommunication network (TCN), its mathematical model is represented as a mixed-dimensional geometric object - a multitensor. Owing to happy choice of coordinate systems for multitensor representation, it is possible to simplify significantly formalization and computation of a number of important network problems of the TCN analysis and synthesis.
