[HYGIENIC REGULATION OF THE USE OF ELECTRONIC EDUCATIONAL RESOURCES IN THE MODERN SCHOOL].

We studied the effect of academic studies with the use a notebook computer and interactive whiteboard on the functional state of an organism of schoolchildren. Using a complex of hygienic and physiological methods of the study we established that regulation of the computer activity of students must take into account not only duration but its intensity either. Design features of a notebook computer were shown both to impede keeping the optimal working posture in primary school children and increase the risk offormation of disorders of vision and musculoskeletal system. There were established the activating influence of the interactive whiteboard on performance activities and favorable dynamics of indices of the functional state of the organism of students under keeping optimal density of the academic study and the duration of its use. There are determined safety regulations of the work of schoolchildren with electronic resources in the educational process.

[Justification of regulations for the use of computers with LCD monitor during academic studies].

In the article there are reported the results of studies of the effect on the functional state of the body of schoolchildren curriculum with the use of personal computers with LCD monitors. The resistance to the development of visual and general fatigue in schoolchildren -users of personal computers with LCD monitors was found to be higher because they provide a more favorable environment for visual work in comparison with monitors based on cathode-ray tube. The use of LED lighting in classrooms contributes to the creation a more favorable light environment than in fluorescent lighting and reduces fatigable impact (both general and visual) of classes with the use of personal computers.

[Current problems of school education and ways of its hygienic optimization].

The aim of the study was to analyse effects of various innovative forms of school education on the health status and functional abilities of children and adolescents. Enhanced academic loads are shown to be the most unfavourable factor of the school environment. The main consequences of excess teaching load are shortened motor and outdoor activities of the children, smaller duration of night sleep. Optimization of academic routine (alternation of studies and holidays), modular structure of school calendar might help to reduce fatigue during school hours. Hygienic estimates of different variants of specialized education are obtained. Scientifically sound hygienic requirements are proposed to be applied to the organization of academic activities in a new type of educational institutions, full-day schools.

[Hygienic requirements for work organization of full-day schools].

Physiological and hygienic studies under the conditions of a natural hygienic experiment were conducted to examine different variants of the organization of work of new types of general educational establishments--full-day schools. Over 580 pupils from 5 full-day schools were followed up. Organization of teaching children at full-day schools was found to mainly correspond to the age-related capabilities of pupils from primary and secondary classes. Of vital importance for maintenance of mental performance, good emotional and psychosomatic states are the organization of the intraschool environment, including a school plot, as well as the conditions for realization of additional education, motor activity of children, and recess. Health keeping in pupils from full-day schools is favored by the reduction in the duration of lessons to 35 minutes and day sleep for first-form children, the decrease in the number of pupils in a class, outdoor physical exercises in the middle of a school day (a primary school) and strolls after lessons, three meals a day, balanced additional education, medicopsychological accompaniment, optimization of studies and rest in children during a school year.

[Modern military school education sociomedical analysis].

The sociomedical status of senior military school students was studied, by examining the formed stereotype of a healthy lifestyle, spiritual and patriotic values, as well as physical health indices. It was established that among the significant spiritual and patriotic values, most (62.3%) cadets reported love for their country in the first three places: 68.4% of the schoolchildren called physical health; 47.6% put a readiness at defending the motherland in the first three places while 53.9% named physical health. Psychoemotional studies revealed a low level of anxiety and neurotization in the cadets than in the schoolchildren. Physical health studies (hand muscle strength, vital capacity, hypoxic resistance) indicated that the senior military school students had higher fitness than the general educational school children. These differences in the physical health indices of the adolescents are chiefly associated with the greater attention given by the cadets to their physical education than that shown by the general educational schoolchildren.

The case study deals with the health status of children at preschool educational facilities as observed in the 80-ies of the last century and early in the new century; besides, an elaboration of hygienic regulations applicable to the training-and-education effects produced on organisms of contemporary trainees of such facilities for as long as 3 to 7 years with due respect to the education modernization campaign (now underway in the country) is in the focus of attention.

[Differential evaluation of environmental factors and health of schoolchildren]. / Differentsialnaia otsenka factorov okruzhaiushchei sredy i zdorové shkolnikov.

The problem in the study of the mechanisms of school-children's health formation during their study at school can be solved by applying a systems approach with the use of a multifactorial analysis which combines a host of some environmental components into a number of risk factors identified from the degree of their impact on the health status of pupils. In accordance with the contribution to the dispersion of signs, the role of intraschool environmental factors increases from 12.5% in primary school children to 20.6% in those leaving the eighth form. As pupils grow up, the contribution of sociohygienic factors decreases from 27.5% at the beginning of school study to 13.8% at its end. The pathological affliction factor is 23.3% on admission to school and little changed (20.8%) in old schoolchildren. In cities, the highest contribution to the impact on schoolchildren's health is made by the natural and climatic factor; climatic conditions and environmental pollution account for 10 and 20%, respectively.

Proceeding from the analysis and statistical processing of the data derived during the study of health dynamics of junior schoolchildren, who studied during an academic year under the conditions of different air exchange regimes (20 and 40 m3 of air per hr/child), it was established that indoor air medium formed by air supply of 40 m3 per hr/child (compared to 20 m3) even during a year had a favorable impact on the functional state of some body systems and prevalence of acute diseases among schoolchildren.
