Description
There are about 575 thousand of citizens in the Krasnodar Region that are entitled to a preferential medical maintenance in accordance with the Federal Law of 17.07.1999 (№178-FZ) "On state social assistance." About 120 thousand of preferential prescriptions for 150 thousand of medicines are serviced per month. In order to make the drugs prescription process based exceptionally on real medical indications in accordance with modern concepts of medical service quality it is necessary to plan the medical-economic drugs prescription validity control (MEC). The work proposes the analysis and synthesis method of decision support system (DSS) modules for automation the selection of drugs prescription and medicinal maintenance cases, concerning the federal benefit recipients, while performing the MEC. DSS allows medical experts to estimate the efficiency of federal funds costs, that are spent on the preferential medicinal maintenance, moreover, it can serve as a basis for future purchases planning, as well as to correct and improve the efficiency of medical prescriptions. The DSS was developed in accordance with the approved procedure of information exchange in the Krasnodar Region; it involves the integration with existing systems. Furthermore, as the federal register of persons, entitled to the state social assistance, has common formats among all the Russian Federation subjects, the developed system can be easily adapted in other regions

Description
The article is devoted to the development of a compressor type ozonator. It describes the design of a high-productivity compressor ozone generator, which can be used for industrial decontamination of mixed feeds, water, milk, and in the system of presowing treatment of seeds. This construction allows generating ozone with high concentration to 5 g/m3 at high feed air or oxygen from the compressor station (up to 2000 l/min). The article describes the design of the basic elements of tubular ozone generator, examines the factors influencing the productivity of the ozonator. The proposed mathematical model allows calculating the productivity of the ozonator when considering multiple influencing factors. These factors take into account: the parameters of supply voltage, such as the magnitude and frequency of the supply voltage; the configuration and geometrical parameters of electrodes such as, the area of the electrodes, the configuration of the surface of the electrodes and distance between electrodes; parameters dielectric barrier; and the transported gas parameters such as volume, temperature, pressure and composition. Special attention is paid to the design of the electrodes made of woven wire mesh with mesh sizes from 1.5×1.5 to 2.0×2.0 mm. It is noted, that such electrodes allow obtaining the maximum productivity of an ozonator, and they do not lead to overheating of the dielectric barrier, and do not output down the generator. In the same way, the article presents the results of the mathematical modeling of ozone generator productivity while changing various factors

To improve the reliability and the efficiency of power supply for responsible consumers, we have proposed to develop energy efficient combined energy-saving systems for uninterrupted power supply with use of renewable energy sources. The article lists major principles of the development of such systems; it shows the necessity of constructing a generalized schema that contains the possible types and the sources of electric power converters. It also reveals the modern requirements to systems of uninterrupted energy supply. To improve the operational and technical characteristics of the uninterruptible power supply, it has been proposed to use a new circuitry that includes a contactless power generators, the direct frequency converters used to stabilize the voltage and frequency of the current generators of wind turbines, static converters made with the use of single-phase transformers with rotating magnetic field, universal static converters that can operate in the regimes of known types of converters. The article presents features of the modular construction of systems of uninterrupted energy supply and optimization of their structural decisions on key performance criteria. It shows the algorithm of synthesis of structural designs of combined systems of uninterrupted power supply. An important step for further research with the aim of improving operational and technical characteristics of the combination of uninterrupted power supply systems is the mathematical modeling of physical processes in power circuits of the system in both normal and emergency modes of operation

Description
Expansion and increasing of the Krasnodar region transport infrastructure during the construction of the Olympic facilities together with the new land development created a necessity for construction in the remote areas of landslide slopes with the complex engineering-geological conditions. Constructions of bored piles, jammed by in nondisplaceable soil are often used as one of the measures for the protection of surface rocks landslide movement and tightening the slope weak sections. Such constructive solution is often being considered the best, and sometimes the only acceptable solution. When designing engineering protection it is recommended to consider the use of a number of active protection activities, aimed at the landslide processes stabilization. However, in case of construction production impossibility due to terms of organization, it is necessary to provide passive protection which would secure that the landslide streamlines the construction. Currently, the mechanism of the soil landslides interaction with constructions of detached objects spot protection isn’t studied enough. Known methods adopt simplifications and assumptions which lead to definite significant errors in the design of slope protection structures. Security and reliability of such structures can only be achieved with the adoption of high factor of safety values. This leads to increased material consumption and labor input for the erection of defensive structures also reduces the economic efficiency of these structures. In addition the process of designing protective structures in the Krasnodar region is further complicated by fact that the landslide of construction area is mainly folded by flowing clay soils
