The article analyzes the technological schemes of sanitation systems, analyzes the technological solutions to improve existing systems. The aim of the work is to develop an effective structural and technological scheme of the sanitary treatment system of the milking unit. When drawing up the structural diagrams of technological lines, an analysis of existing technologies was used. To determine the rational working scheme of sanitation, a systematic approach is needed with a thorough analysis of existing structures, parameters that determine the effectiveness of its functioning. Structural diagrams are a chain of successively arranged operations.

In Italy, studies on wooden structural elements in masonry buildings, from the Middle Ages throughout the Modern Age to the twentieth century, are few in number compared to other European countries and present no systematic approach. It is necessary to carry out progressively, but systematically, high-detailed surveys and to correlate them with the existing discontinuous documentation. Diachronic comparisons – referring to significant geographical areas in which evident constructive constants are recognizable – would highlight the variation over time of the models and their diffusion, while the comparison, especially synchronic, between solutions evidently different or apparently similar, would allow to better understand both the constructive choices and their static behaviour. A series of models – including the structural ones – should be elaborated, for directing design in a sector, often seriously flawed, prone to simplification and the introduction of high safety factors essentially motivated by summary and inadequate surveys of the actual situation. It is also interesting to evaluate the application of mensiochronological techniques to the analysis of timber structures, especially floors. The significant measures for dating are various: dimensions and centre distances of beams and joists, width and thickness of the boards, dimension of the accessory elements (e.g. joint laths), but the working processes and tree species have a decisive impact on the measures of the artefacts. Mensiochronological techniques usually detect slow but evident variations; however, a centuries-old constancy is equally significant. More general information about the context is useful, in particular which choices are not determined by mere technical reasons. A better historical knowledge serves to understand the qualities and limitations of existing structures, and the features – including decay – in which they appear.  The floors of Palazzo Magio in Cremona, dating from the fifteenth century to the end of the eighteenth century, allow to reflect on how and what to examine.

The article is aimed at outlining the possibilities of applying the conception of structuralism in order to interpret the indicators of the components (constituents) of the efficiency of enterprises as micro level systems in terms of the paradigm of «structure – system» taking into account the history of the origin and development of the mentioned conception. The article presents the results of a study of the evolution of concepts «structure» and «system» in the context of the relevant paradigm in view of improving approaches to management of the performance of enterprises. The interpretation of the above mentioned definitions by different scholars is provided; the author’s own interpretation of the concepts of «structure of performance indicators» and «system of constituent performance indicators» of enterprises activity are proposed. Methodological approaches to managing the performance of enterprises as complex micro level systems based on the above mentioned system of indicators based on the models of Burennikova (Polishchuk) – Yarmolenko are outlined. The structural-logical scheme of basic concepts in the paradigm of «structure – system» is proposed. The «model of interrelation» between the concepts of «structure» (quantitative and qualitative constituents of performance indicators) and «system» (as a multiplex, a set of interrelated elements, a complex of related performance indicators) is presented in a systematic approach of scientific cognition in order to more clearly identify the relationships between the studied concepts and related indicators with taking into account the system approach. It is emphasized that the lack of results of computations on certain components (constituents) of the specified system of indicators makes it impossible to create a holistic picture regarding the performance of enterprises. It is underlined that the improved by the author methodology of knowledge, measurement and evaluation of the performance of enterprises will contribute to improving their management and finding reserves for the development of enterprises as systems.

The article describes the shortcomings of existing structures and units of pneumatic grain seeders. There was analyzed the technological process of distribution of seed material in distribution systems. There were described the various options of developed designs of dosing and distributive systems allowing to increase the sowing machines efficiency. To improve the efficiency of sowing machines, it is proposed to establish a distribution of seeds with a downward flow, which will increase the uniformity of seed supply to coulters and, consequently, increase the uniformity of their distribution over the field surface.

Abstract The purpose of the paper is to develop a model for managing the motivation of managers and ensure its effectiveness. The principles of formation of management model of managers’ work motivation which correspond to the universal system approach to management model of managers’ work motivation and define its basic functions are outlined: a) goal setting, b) assessment and forecasting of the state and efficiency, c) development and decision making, d) planning, e) organizational, f) communication and subordination, g) regulation of the management model of motivation of managers, h) control. The management model of managers’ work motivation of (MMMWM) is formalized in the form of a structural-logical scheme based on a systematic approach and decomposition, which reflects the interaction of subject and object in the process of forming and implementing a system of motivation of managers at the enterprise. The factors for achieving the set goals have been formed, which are divided into internal and external motivators for managing managers’ work motivation. The management model of managers’ work motivation which is presented by the following subsystems is offered: “X” – target subsystem (the management process of managers’ work motivation), “Y” – providing subsystem (factors of rational achievement of the goals), “XY” – providing subsystem (regulatory legal acts, resources), “Z” – management subsystem (reflects the implementation of the general functions of management work motivation on the basis of experience), which are characterized by parameters, indicators, criteria for managing the motivation of managers. According to the method of linear multiple regression, a system of equations was constructed to describe the economic-mathematical model of management motivation at oil and gas enterprises, which after the repeated experiments provided diagnostics of indicators before, during and after the implementation of management motivation model.

Introduction. Current trends in the development of sports dance indicate the impact of modern knowledge of sports science on the system of improving the functional support of special performance of dancers. The lack of a systematic approach to the management of training loads significantly affects the formation of specific methodological approaches to improving the special performance of dancers, taking into account the specific characteristics of training inherent in sports that combine sports and art. The aim is to develop a systematic approach aimed at modeling the special functional training of dancers, taking into account the specific requirements of training in sport dances. Material and methods: analysis of special scientific and methodical literature. Theoretical research methods: analysis, synthesis, comparison, generalization, concretization, systematization. Results. The structure and algorithm of realization of modeling of special functional preparation in sports dance are developed: 1) Structural organization of the analysis directed on formation of the system approach to modeling of sports training. 2) Specific principles of forming a systematic approach to modeling the training of dancers. 3) Structural and logical scheme of modeling the functional readiness of dancers. 4) Characteristics of models of training of athletes-dancers. 5) Aids for modeling the readiness of athletes in sport dances. Conclusions. The system approach is developed on the basis of the model-target approach of realization of modeling as functions of management of special functional preparation of athlete-dancers. The formation of the structural components of the model-target approach requires taking into account the specific components of training and preparedness inherent in sports that combine sport and art.

This article presents a systematic approach to solving a problem with rational use of an airport’s water resources. Life cycle programming of the technological systems of wastewater purification allowed to consider comprehensively the problem of economical water consumption. The life cycle programming was adopted as the methodological basis for constructing a logical scheme of tasks of an airport’s water-saving processes. On the basis of the proposed logical tasks diagram it became possible to develop an algorithm and software for automatized control over airport’s water-saving processes. The purpose of the work is to implement a systematic approach for control over water-saving production aviation processes of the airport and representation of the developed algorithm for control. It may be concluded that the implementation of the given algorithm on the basis of computer technology will increase the efficiency of wastewater purification and significantly reduce the fresh water consumption.

In order to make a breakthrough for the acute problem of water shortage in the world, the key words “decentralization and re-use” are very important for new sustainable sanitation systems that will be developed. Therefore, we focused on a new treatments system called “a slanted soil treatment system” which combines a biotoilet system with a domestic grey water treatment system. Because this system is a low cost and compact system, the system can be easily introduced to homes in urban areas or in the suburbs of cities in many developing countries. In this study, we performed on site experiments carried out on Shikoku Island, Japan, for several years. We obtained the following results. The slanted soil treatment system could remove organic pollutants and total nitrogen and total phosphorus in grey water effectively. Furthermore, the system performance became high in the case of the high concentration of the influent water. The nitrification reaction and denitrification reaction were speculated to exist due to aerobic zones and anaerobic zones present in the slanted soil treatment system. The slanted soil treatment system could perform for approximately 3 years with zero maintenance. The plug flow model of 1st order reaction kinetics could describe the reaction in the slanted soil treatment system. However, it is necessary to improve the system to maintain the performance in all seasons.

Climate change is among the major challenges that are increasing the risk of extreme weather events, such as increases in the strength and frequency of heavy precipitation, floods, and drought. Technologies currently promoted for improving access to sanitation are vulnerable to climate-related threats. In today's context where nearly 2.5 billion people do not have access to sanitation, climate change is an additional hurdle in ensuring them access. Climate change, its impact on sanitation systems and their scope of adaptation must be addressed to accelerate sustainable sanitation coverage. This paper attempts to analyse the vulnerability and potential adaptability of certain sanitation systems with a focus on floods and will provide guidance on systems selection. The waterless system with urine diversion has the components necessary to cope with a flood situation, while the waterless system with alternating pits and the pour flush system with twin pits are less suitable. The (semi-)centralized treatment system is the least adaptable system. This paper recommends action research on the vulnerability and adaptability of sanitation systems in order to make informed choices based on future climatic projections to ensure sustainable sanitation systems in the face of climate change.
