[New methodological approaches to the hygienic standards of clothes for children and adults].

The hygienic assessment is presently a research issue related mainly with commissioning new materials into production; the above issue is equally related with materials' diversity, with expanding the choice of commodities and with the multi-functionality of the latter as well as with modern technologies and with the forthcoming admittance of our country to the WTO, which necessitates a harmonization of regulating requirements in various countries. The old approaches towards regulations of cloths are outdated and are no longer in line with the requirements of today. The chemical stability of contemporary synthetic fibers and the narrowing-of-gap between their physical-and-hygienic indices and those of natural fibers ensures unified approaches towards the hygienic evaluation of both. A real load that is conceptually found as a product of the impact intensity on the impact duration time is a hygienically valuable criterion ensuring a universal approach towards regulating the cloths hygienic safety. A hygienic classification provides, in case of each item, for defining the index of its hygienic safety (HIS), which is a basis for designing the differential requirements towards cloths of various functional purposes and for various age groups. The area of contact with the skin during wear and the age of consumer are the key components of system (The Hygienic Classification of Cloths". The article is supplemented by 1 drawing, 2 tables and a list of literature (8 entries; article's volume is 5 pages).

[Hygienic evaluation of basic elements of preparation of the texts for printed publications].

The influence of the main elements of the composed matter (set and print size, line length, inter-lines space) on the legibility of mass periodicals was evaluated in experimental studies on volunteers. A complex of composed matter parameters increasing the legibility of the printed issues texts for the adults was established. The developed recommendations are important for the protection of readers' eye sight.

[Sanitary classification of publishing products].

The natural asthenopic pattern of the process of reading shows it necessary to set sanitary standards of publishing production, namely, printing type styling and the printing quality of publications. The necessity of sanitary classification of publishing production stems from the specificity of reading the publications of different functional uses and from the physiological features of vision in different age group readers. The developed sanitary classification of printing production is based on the researches into the actual visual load while reading the publications of different types by readers of different ages.

[Health-related requirements for the print design of illustrated texts in publications intended for children].

The fact that there are essential differences in the volumes of texts for continuous reading in the belles-lettres and those for episodic reading (encyclopaedias, comic books, etc.) and marked differences in the area of the type pages intended for illustrations made it necessary to substantiate differential requirements for these groups of publications. Hygienic requirements were corrected by using the data obtained from 150 experiments covering 36 secondary-form pupils. Based on the well-known data on temporary visual fatigue thresholds (TVFT) and on the experimental findings, the authors defined the ratio of higher TVFT to the actual time of reading the texts of different volumes. A complex of print design indices to be hygienically regulated varies with the multiplicity that is in fact a safety factor.

[Hygienic rationale for the allowable weight load of a daily training complex for schoolchildren].

Computed posturography (stabilography) was used to examine the locomotor function of 165 children from 1-11 forms under the influence of different real and model loads. Analysis of age-specific changes in their upright stability (by the data on the lateral velocity of the body's oscillations) yielded allowable load weights of a daily complete set for schoolchildren.
