THE CONCEPT OF DEONTOLOGY AND ITS PEDAGOGICAL ESSENCE
This article examines the concept of deontology, its philosophical and pedagogical foundations, and its significance in the education system. Deontology is interpreted as a theoretical field based on the principles of professional duty, moral norms, and responsibility, regulating human behavior in professional activity. In the pedagogical context, deontology plays a crucial role in shaping teachers’ professional ethics, humanistic values, and respectful and fair attitudes toward learners. The article reveals the pedagogical essence of deontology and its interrelation with empathy, communicative culture, and professional responsibility. In addition, the methodological foundations for developing deontological culture among future teachers and the possibilities of its implementation in the educational process are substantiated. The findings indicate that the deontological approach serves as an important pedagogical tool for the development of teachers’ professional and moral qualities

MATHEMATICAL MODEL OF GROUNDWATER LEVEL DYNAMICS AND SALT MIGRATION IN A POROUS MEDIUM
This paper investigates the mathematical modelling of groundwater level variations and the transport of salt concentration within porous media. The filtration behaviour of groundwater is described based on the Dupuit–Forchheimer assumption, while the governing equation for groundwater level dynamics is derived from the law of mass conservation, resulting in a nonlinear differential equation of the Boussinesq type. In addition, the migration of dissolved salts within the porous medium is represented through a convection–diffusion equation. During the salt transport process, the filtration velocity is determined by the groundwater discharge, and the interdependence between groundwater level and salt concentration is incorporated into the formulation. As a result, a coupled mathematical model describing both groundwater level fluctuations and salt concentration dynamics has been developed. Appropriate initial and boundary conditions are specified for the proposed model, and the physical interpretation of the governing processes is discussed. The developed model provides a framework for analysing the hydrodynamic regime of groundwater and the spatial–temporal distribution patterns of salt transport in porous media. Furthermore, the proposed approach can be applied to evaluate groundwater level changes in irrigated regions, to predict soil salinisation processes, and to support the rational management of water resources.

INTENSIFICATION OF THE GAS FUEL COMBUSTION PROCESS IN CHAMBER FURNACE BURNERS
This paper analyzes the methods of intensifying the combustion process of gaseous fuels in chamber furnaces. The characteristics of diffusion and kinetic combustion in burners, which are the main elements of the fuel system, as well as their aerodynamic modes and flame front stability, are examined. Changes in heat load are expressed in mathematical models based on factors related to the turbulent flame propagation velocity and the intensity of heat and mass transfer. In addition, ways to improve heat generation efficiency by increasing the flame surface-to-volume ratio, the advantages of slot and grid burners, the effect of preheating air and fuel, and environmental limitations are analyzed. The results make it possible to determine optimal parameters to increase furnace efficiency and ensure combustion stability.

INTELLECTUAL METHODS OF MODELING AND MANAGEMENT THE REFINING PROCESS BASED ON VIRTUAL ANALYZERS
The article examines an approach based on the construction of intelligent virtual analyzers, which calculate the values of difficult-to-measure quality indicators based on the current readings of technological parameter sensors. A methodology for forming such models under conditions of noise, incomplete, and temporarily dissynchronized data is proposed. A probabilistic maximum algorithm is used to clarify time delays, partial least squares regression for working with multicollinear inputs, nonlinear transformations, analysis methods, and training sampling formation. It has been shown that the implementation of the developed virtual analyzer allows for a decrease in the average error of quality forecasting by tens of percent, stabilizes the refining regime, and ensures a reduction in energy consumption and losses of the target product.

FORECAST OF DROUGHT DYNAMICS IN KARAKALPAKSTAN USING MODIS DATA AND THE HURST INDEX
Drought is one of the most serious natural phenomena negatively impacting arid regions, including Karakalpakstan in the Aral Sea basin. This study used MODIS remote sensing data (NDVI and EVI) to analyze the spatiotemporal dynamics of vegetation and drought in 2015–2024. Changes in vegetation cover were assessed and areas with the most pronounced declines in vegetation indices were identified. It was found that a significant portion of Karakalpakstan is characterized by persistent signs of vegetation degradation, especially in the central and western regions. The results confirm the high effectiveness of MODIS satellite data for monitoring drought conditions and highlight the need to develop adaptation measures in agriculture and water management.
