The challenge of degradation of natural ecosystems because of human activity is considered by the world community to the most serious problems facing mankind. As a result of mineral extraction, man-made landscapes and environmentally ruined areas replace natural habitats and agroecosystems; a whole spectrum of man-made processes are typical for such landscapes, which leads to a decrease in species richness and biological diversity within such areas. Degraded territories formed in the process of coal mining are often partially restored through remediation measures. During the implementation of the technical stage of remediation, substrates with different potential fertility having different environmental properties and quality are used. Specific features of distribution total, available nitrogen concentrations and levels of urease enzymatic activity at the layers of artificial soil, sod-lithogenic soils onto gray-green and red-brown clays and on loess-like loams in the Nikopol manganese ore basin are established. It is presented general assessment of technosol status by concentration of general easily hydrolysed nitrogen enzyme activity of urease and this enzyme enriches the soil with mineral nitrogen in the process of mineralization of organic substances. The level of activity of urease, investigated soils, determines the intensity of the direction of biochemical processes that affect soil fertility.High correlation between concentrations of soluble nitrogen and urease activity values by layers of artificial soil (r = 0.81), sod-lithogenic soils onto gray-green (r = 0.98), red-brown clays (r = 0.72) and onto loess-like loam (r = 0.85) were found. Tendency of decreasing hydrolytic enzyme activity, urease, with depth in all types of artificial soil studied was established. It has been established that biochemical diagnostics of technozem processes beyond the level of activity of the hydrolytic enzyme urease makes it possible to estimate the direction of changes at the layers of artificial soil, sod-lithogenic soils onto gray-green and red-brown clays and on loess-like loams. The recultivated soil has some what lower fertility and greater salimity at the lower horizons, but is capable of performing ecological functions and can not only be used for economic purposes, but also perform ecological functions.

The article presents the results of the analysis of the problem of digitalization of ed-ucation. Interrelations of digitalization of ecological education with noospheric essence of modern civilization and realization of the concept of sustainable development are established. Possibilities of use of developments of the Russian and foreign scientists and teachers are con-sidered. The importance and main directions of development of digitalization of environmental education are shown. Attention is drawn to the need for digitalization of environmental educa-tion in the preparation of not only environmental specialists, but also specialists in other areas of training. Digitalization of education should be aimed at the formation of eco-cultural compe-tencies. The article presents the results of an experimental study of the use of modern IT by various participants of the educational process. The studies were conducted by questionnaire method and allow to indicate the current directions of further development of digitalization of education, including environmental education.

Specific features of distribution total, available phosphorus concentrations and levels of phosphatase enzymatic activity at the layers of artificial soil, sod-lithogenic soils onto gray-green and red-brown clays and on loess-like loams in the Nikopol manganese ore basin are established. It is presented general assessment of technosoil status by evaluation of phosphatase enzyme activity; this enzyme enriches the soil with mineral phosphorus and thereby improves its availability for living organisms. Among current bioindication methodology, soil enzymatic method is the most reliable and promising because enzymatic activity serves a stable indicator of soil biogenicity in comparison with other indicators. Soil enzymatic activity determines both intensity and targeting of biogeochemical processes. High correlation between concentrations of soluble phosphorus and phosphatase activity values by layers of artificial soil (r = 0.87), sod-lithogenic soils onto gray-green (r = 0.77), red-brown clays (r = 0.62) and onto loess-like loam (r = 0.95) was determined. Tendency of decreasing hydrolytic enzyme activity, phosphatase, with depth in all types of artificial soil studied was established. High efficiency of the enzymatic activity study in diagnostics of soil fertility dynamics under impact of various anthropogenic and natural ecosystems was determined. Advantages of using this method are capability to determine rapidly the changes occurring in ecosystems in the early stages of degradation processes and prediction of their targeting and, accordingly, their intensity. It has been found that levels of phosphatase activity and values of mobile phosphorus compounds in complex biogeocoenotic systems are sensitive quantitative indicators of changes in environmental conditions in man-made environment, and they generate good data about processes occurred within the soil column. The use of phosphatase activity level can be a reliable and promising method on biomonitoring of technogenic edaphotops.

The University of British Columbia (UBC) in collaboration with a software developer (Planmeca Oy, Finland) created an electronic oral health record based on the principles of cognitive ergonomics rooted in the European research and development project 'ORQUEST' to guide students through medical, dental, social histories, examinations, treatment planning and progress notes. Clinicians in each dental specialty of the Faculty of Dentistry and software engineers cooperated to define the clinical content and workflow of clinical procedures in three phases: (i) development of a radiographic module, (ii) development of medical, dental, social and family histories, intra- and extra-oral examinations, progress notes and treatment planning and (iii) development of the orthodontic section accompanied by an optimisation phase to correct technical problems and clinical content issues. From a practical perspective, this EOHR enhances the clinical performance of students and the quality assurance capacity of the institution. It facilitates audits of clinical productivity and research, and it can be modified with relative ease to suit similar educational and clinical environments in either public or private healthcare settings.
