Ecological culture is considered as the position of man in relation to nature, a form of manifestation of ecological consciousness, organically included in the system of philosophy as knowledge integration, self-awareness and goal-setting personality. It is formed in the process of environmental education, which is a creation of conditions for the assimilation of the personality of ecological culture established by society, with its inevitable change in the succession of generations. Ecological culture is embodied in real human behavior. Environmental consciousness is the highest level of mental reflection of the natural and artificial environment, his inner world, a reflection of the place and role of man in the biological, physical and chemical world. It acts as a continuously changing collection of sensual and mental images that are directly reflected in analytically generated categories and phenomena, directly fixing individual or the public environmental expertise. The content of consciousness does not coincide with the worldview: a worldview is a specific form of consciousness, which includes fundamental, the most common ideas that define the worldview of a person and which are the results of generalization of knowledge, personal experience, emotional evaluations. For environmental awareness the role of ecological culture as a necessary part of the worldview. Components of ecological culture are: understanding the nature and complexity of natural phenomena, their interrelations; the integrity of the knowledge about the environment; the ability to think within the boundaries of the ecological safety; adherence to laws that protect the natural environment; the ability to create a constructive ethical regulations governing human relationships with the natural environment; willingness to accept responsibility for the safety of the environment. Ecological culture is analyzed from the standpoint of the system, activity, socio-cultural and informational approaches. Ecological culture guides human behavior in the direction of harmonization of social and natural relationships and is a component of its security.

Ecological culture includes dialectically interrelated elements: environmental knowledge, environmental awareness and environmental activities. Environmental knowledge is the basis, the Foundation of an adequate attitude towards environmental problems. In the content of environmental knowledge differentiated socio-environmental and real practical knowledge. Environmental activities covers activities associated with cognition, development, transformation and preservation of the natural environment. Environmental awareness is seen as a higher level of mental reflection of the natural and artificial environment, his inner world, a reflection of the place and role of man in the biological, physical and chemical world. Environmental culture is appropriated by man in the process of environmental education. Environmental education in a broad sense is considered as socialization, the process of mastering by the person of a certain system of ecological knowledge, norms and values that allow it to function as a full member of society. The means of formation of ecological culture are the youth's participation in international, national and regional scientific, ecological and educational research projects on monitoring of the environment, in socially significant actions in support of the protection of nature reserves and nature monuments in the greening of cities, towns, villages, improvement of the ecological environment of residential and business premises. Environmental education in the narrow sense is a part of moral education, the unity of ecological consciousness and behavior, harmonious with nature. Priority areas and mechanisms of formation of ecological culture are: promotion of environmental culture and ethics, the development of an effective national system of ecological education of the population, the organization of a national system of ecological education, ecological culture formation and development of civil society. Formation of ecological culture of students of technical University includes the assimilation of ecological knowledge, the development of ecological consciousness and skills ecologically correct behavior with the use of active learning methods and ethical principles.

One of the parameters determining the efficiency of cleaning the blood in hemodialysis therapy is an effective mass transfer processes of metabolites through the dialyzer, which is defined by the mechanism of molecular diffusion and convection of low and medium weight substances in the blood. The article presents an analysis of modern mass transport models: streaming and kinetic; the analytical expressions of the spatial and temporal distribution of metabolites in the dialyzer. The results of mathematical modeling showed that these models do not reflect the full extent of the entire mechanism of mass transfer and must be supplemented. This is primarily due to the fact that blood is a non-Newtonian fluid. In addition, during hemodialysis, there is a change of the rheological properties of the blood - viscosity aggregated and deformability of erythrocytes, which ultimately affects the dialyzer mass transfer processes, reduces its clearance and thus reduces the efficiency of hemodialysis. The authors consider that the solution to this problem might be to develop a space-time mathematical model of mass transfer (the so-called distributed model of mass transfer), built with the influence of the driving forces behind the transfer of substances through the membrane dialyzer basic parameters and characteristics of fibers and rheological blood properties. In our view, the space-time dependence of the distribution of concentrations of metabolites in the blood and dialysate hemodialyzers allow to predict normalization the concentration of metabolites in the blood, and thus improve the accuracy of assessing the quality of dialysis.

This study analyses fractal characteristics of open-loop and closed-loop control mechanisms for different conditions of the sensor control. The stabilogram acquired using three types of the sensor control: open eyes (OE), closed eyes (CE) and visual artificial feedback (VAF). To determine the difference in control mechanisms for different condition of sensor control we have applied the method, offered by Collins J.J. and De Luca C.J. This method is based on the calculation of the Hurst exponent. We did not reveal significant differences (p>0,05) for control mechanisms between OE and CE parameters. However, there were significant differences for control mechanisms between VAF and OE parameters. We revealed that VAF reinforces open-loop and closed loop control mechanisms in anteroposterior directions, as well as VAF reinforces closed-loop control mechanisms in mediolateral directions. It may be important, in a rehabilitation setting, to identify which one of the two components of postural control (open loop or closed loop) needs more reinforcement in a particular patient, and consequently design an optimized device to improve postural balance.
