Providing reliable and relevant data for decision-making is the foundation for efficient and effective state policy on land management and real estate in general. In Ukraine and balance-owners of real estate, utilities, roads and communications have not always have information about their facilities with reference to existing geodetic network and do not commit action for making such information to the relevant inventories. On a separate note that in land and urban cadaster almost no information on most utilities, roads and communications and their forming mode security zone. Lack of information and communication engineering services prevents efficient work planning and territorial development of Ukraine. Analysis of existing inventories imperfect approach also shows the formation of objects of land relations and the information about actual land use (information about the land on which the immovable property is paid, usually initiated by the owner of the property, not the owner of the land initiative), which in turn is the main reason for the shortfall payment for the land the different levels. In the article the analysis of modern municipal geoinformation support of local communities in Ukraine, proposed primary ways to build on existing technical materials and a new database created with modern technology. These GIS even more relevant in terms of administrative and territorial reform in Ukraine and are suitable for use in combined local communities.

Raising of problem. During the reform of land and property relations, has been carried out in Ukraine since the early 1990s, land plots and buildings received the status of goods, participate in economic turnover, have value and price. At the same time, not the most important prerequisite for the introduction in Ukraine of a mass valuation of real estate, which is intended to become a base for the fair taxation of land plots and other real estate, should be the systematic collection of mass data on the market prices of real estate. Constant changes, additions and improvements to the current normative monetary assessment of land do not give a real change in the methodology of assessment because it is based on regulatory indicators, there is a non-market based assessment. This approach does not give positive results and in the overwhelming majority we distort the evaluation indicators. As a result, there is a situation where in some places the price of a square meter is much lower than the market (real) price, while in others it is much higher than the actual price. Thus, the transition to the use of monetary land valuation, which is based on mass market indicators (mass valuation), will get rid of the regulatory indicators by introducing a market valuation base. Purpose. Conduct an analysis of the current state of monetary valuation of land in Ukraine, form the main problems of the modern land assessment area and guide the ways to improve and transition to market valuation of land based on widespread use of mass data on market prices of real estate. Conclusion. The analysis of the current state of the monetary valuation of land shows a significant deviation of the evaluation results with real market prices, indicating the imperfection of the existing method of normative monetary evaluation. Mass evaluation in the short term can solve the problems with the reliability of the estimates and improve the system of land taxation.

Formulation of the problem. Total hip replacement (THR) remains to be responsible for the markable clinical achievements of contemporal orthopaedic surgery [1; 2; 4]. It should be noted, that numerous efforts to create an “ideal” uncemented hip endoprosthesis’ construction were failed, but led into wide diversity of implants. Such a diversity allowes to individualize implant type selection and to improve implant’s survival and total THR’s clinical outcomes [1; 4]. Outcomes mentioned above determine successful application of total hip replacement as a treatment method. Consequently, development of new and improvement of existing hip endoprosthesis’ constructions seems to be of current interest for contemporal orthopaedic surgery. Purpose. To determine optimal parametres of threaded element’s geometry of total hip endoprosthesis’ threaded acetabular component. Conclusion. There were revealed that threaded element model with right-angled triangle transverse section shape seems to be the most effective considering hardness, while the triangle is leaned on the bone massive with its cathetus. At the same time, results of calculations represent pelvic bone stress-strain state during THR quantitavely and stipulate further research.

Problem statement. In the next 10 years, more than 90 % of materials will be replaced with new materials – nanocomposites [1]. The nanocomponents application will allow manufacture of high-strength materials with reduced production cost and will ensure demand for products [2]. Researches aimed to determination of carbon nanotube type nanomodifier concentration impact on the physical and mechanical properties of gypsum binders are important today and must result in creation of competitive strong nano-materials. Purpose. Research of carbon nanotube (CNT) type nanomodifier concentration impact on the physical and mechanical properties of gypsum binders. Conclusion. Sample microstructure analysis revealed that the non-modified gypsum sample structure is dominated by prismatic and lamellar crystals randomly distributed throughout the matrix volume. In this case, loose structure with increased porosity is formed, which results in sample mechanical strength reduction. In the CNT-modified gypsum matrix, well-ordered and homogeneous structure is formed with larger needle-shaped crystals, which results in the phase-contacting area increase, porosity reduction and thus the physical and mechanical characteristics improvement. It is experimentally proved that at the identical nano-modifier content in the gypsum matrix (0.035 %), maximum compression strength gain is achieved with the use of CNT and makes 28‑ 30 %. At the use of initial carbon nanotubes, increase in strength at the same nano-modifier content makes 13‑15 %. The Ca2+ ions interaction with the graphene-like carbon surface was investigated by the DFT method. Capability is demonstrated of the covalent calcium bonding with the hexagonal carbon surface cell as a result of overlap of Ca2+ valence 3p orbitals and carbon 2р orbitals.

Considering the city as an open dynamic system, it can be concluded that at such level of complexity the system can not exist without a lot of internal contradictions. Each of these contradictions separately, or in combination, causes the city to change in such a way that they do not threaten the system existence. Architecture, as an artificial environment in which system conflicts and systemic contradictions are occurring, has also to react flexibly to them, changing in turn.

Problem Statement. A significant part of Orthodox churches in Ukraine, which are architectural monuments, are in unsatisfactory condition. This is due to the lack of timely care for them and the termination of their operation. It should be noted that one of the most important missions of mankind is the prevention of the disappearance of cultural heritage and its preservation for the next generations. Therefore the issue of restoration of Orthodox Church buildings require comprehensive study. Restoration of churches is accompanied by some organizational and technological difficulties. There is complex architectural and spatial shape of the building and the peculiarities of carrying out repair and restoration works. The purpose of the article. The purpose of the article is to highlight the developed organizational and technological solutions for restoring the covering structure. Conclusions. The complex of repair and restoration works should be divided into three stages (preparatory, main and final). A significant period of production takes the preparatory stage (41 %). Performing repair and restoration works by the flow method allows to maximize the use of labor resources and a set of construction machines. The use of scaffolds and a modern formwork system for the re-establishment of the central vault allowed to reduce the labor intensity of work, which in turn led to a reduction in the number of employed workers and an increase the pace of work.

Raising of problem. Constructions and buildings can be destroyed or damaged from the action of technogenic catastrophes, failures and natural phenomena. An accident takes place, if a rightness is violated: project decisions and normative descriptions, making of plant wares, building editing. On occasion building get damages as a result of action of some not alone factor, and their total action. Dismantling of the damaged constructions is executed without the account of destructions character of objects, in particular their upper floors and roof. Therefore determination of character of destructions of overhead floors of buildings, constructions and development of technological decisions on their renewal is the scientific and technical issue of the day. Purpose. Determination of of destructions character of upper floors of building, as initial information for making decision on realization of works. Conclusion. The most frequent reasons of destructions of upper floors of building are: increase of loading over normative; decline in the process of exploitation the descriptions on durability of constructions from the action of various factors ‑ of moisture, temperature, wear. Destructions of building have a credible character. At the same time there are separate conformities to law of their destruction and general chart of development of this process. The local damages of separate elements of buildings and constructions which spread to the contiguous constructions and knots pass at first. Then the volume expansion of destruction or damage passes in the direction of the explosion source action.

Formulation of the problem. Significant influence on the quality of rolled steel have various defects on its surface, which in its turn inherited from surface defects of billet and possible damage to the surface of rolled steel in the rolling mill line. One of the criteria for assessing the quality indicators of rolled steel is rationing of surface defects [1; 2; 3; 6; 7]. Current status of the issue. Analyzing the different requirements of regulations to the surface quality of the rolled high-carbon steels, we can conclude that the maximum allowable depth of defects on the surface of billet should be in the range of 2.0...5.0 mm (depending on the section of the billet, method of its production and further the destination) Purpose. Develop a methodology for calculating the maximum allowable depth of defects on the steel billet surface depending on the requirements placed on the surface quality of hot-rolled steel. Results. A simplified method of calculation, allowing at the rated depth of defects on the surface of the hot-rolled steel to make operatively calculation of the maximum allowable depth of surface defects of steel billets before heating the metal in the heat deformation was developed. The findings shows that the maximum allowable depth of surface defects is reduced with increasing diameter rolled steel, reducing the initial section steel billet and degrees of oxidation of the metal in the heating furnace.

Formulation of the problem. Sustainable and successful functioning of the organization in today's competitive market conditions is possible if the organization is an open dynamic system capable of timely and adequately adapt to changes in the environment, this organization should initiate the implementation of innovations, both in production and organizational structure. Most suited for these conditions are project-oriented organizations, when the program's development strategy is developed with a detailed individual relatively independent stages, which are implemented as part of projects. In accordance with the development and improvement of the organization of control systems in the direction of increasing emphasis on the development strategy in relation to operating activities is an important task. Goal and tasks. Explore the hierarchical control system of project-oriented organization towards establishing information flows combine program management system with project management subsystems, included in this program. Conclusions. Concretized the concept of “program” and “project” as a result assumed that the program management is a permanent process in the organization that is adaptable to external changes, and project management (as defined) is temporary, so the project management structure are subject to program management structures and are not permanent in the organization's management system.

Raising of problem. Natural calamities, technogenic catastrophes and failures, result in destruction of building objects. Under the obstructions of destructions there can be victims. The most widespread technogenic failure are explosions of domestic gas. The structure of obstructions changes depending on parameters and direction of explosion, first of all size and location of wreckages. Sorting out of obstructions is executed by machines and mechanisms which do not answer the requirements of these works, that predetermines falling short of logistical support to the requirements of rescue or restoration works, and it increases terms and labour intensiveness of their conduct. Development of technological decisions is therefore needed for the effective sorting out of destructions of building objects. Purpose. Development of methodology of determination of logistical support of processes of sorting out of destructions of building and building. Conclusion. Experience of works shows on sorting out of the destroyed building objects, that they are executed with the use of imperfect logistical support, which are not taken into account by character of destruction of objects and is based on the use of buildings machines which do not answer the requirements of these processes, that results in considerable resource losses. Building machines with a multipurpose equipment, which provide the increase of efficiency of implementation of rescue and restoration works, are worked out. Methodology of determination of number of technique is worked out for providing of material-supply of sorting out of destructions, in particular on the initial stage of rescue works for liberation of victims from under obstructions.

Problem statement. Until now slide bearings are used widely in engineering. But the calculation is made on obsolete method that is based on undetermined parameters such as wear of the bearing shell. It is accepted in the literature that if the shaft and liner material are homogeneous, the workpiece surface are cylindrical as they wear and contact between them occurs at all points contact arc. Research objective. The purpose of this study is determine a friction torque in the slide bearings of power-basis parameters. Conclusions. Since the friction is primarily responsible for wear of cinematic pairs “pin – liner” and “pivot — liner” slide bearings. It is shown that the friction torquesof angles wrap, that are obtained by the formulas and given in literature, are not only qualitatively but also quantitatively, namely, the calculation by literature to the formulas the friction torques are proportional to the angle wrap and the calculation by improved formulas the friction torques are inversely proportional to the angle wrap due to the reduction the normal pressure. Underreporting friction torque at large angle wrap is between 40 and 15 %. The difference in the magnitude of friction torque in the run-in and run-out cinematic pairs with real method of machining is 2...3 %, which it is possible to declare of reducing the finish of contacting surface of slide bearings.

Problem statement. Ecopolices are the newest stage of the urban planning. They have to be consideredsuchas material and energy informational structures, included to the dynamic-evolutionary matrix netsofex change processes in the ecosystems. However, there are not made the ecopolice classifications, developing on suchapproaches basis. And this determined the topicality of the article. Analysis of publications on theoretical and applied aspects of the ecopolices formation showed, that the work on them is managed mainly in the context of the latest scientific and technological achievements in the various knowledge fields. These settlements are technocratic. They are connected with the morphology of space, network structures of regional and local natural ecosystems, without independent stability, can not exist without continuous man support. Another words, they do not work in with an ecopolices idea. It is come to a head for objective, symbiotic searching of ecopolices concept with the development of their classifications. Purpose statement is to develop the objective evidence for ecopolices and to propose their new classification. Conclusion. On the base of the ecopolices classification have to lie an elements correlation idea of their general plans and men activity type according with natural mechanism of accepting, reworking and transmission of material, energy and information between geo-ecosystems, planet, man, ecopolices material part and Cosmos. New ecopolices classification should be based on the principles of multi-dimensional, time-spaced symbiotic clarity with exchange ecosystem networks. The ecopolice function with this approach comes not from the subjective anthropocentric economy but from the holistic objective of Genesis paradigm. Or, otherwise — not from the Consequence, but from the Cause.

Raising of problem.Non-compliance requirements of today's industrial enterprises, which were built during the Soviet period, as well as significant technical progress, economic reform and transition to market principles of performance evaluation leading to necessity to change their target and functionality. The technical condition of many industrial buildings in Ukraine allows to exploit them for decades.Redesigning manufacturing enterprises allows not only to reduce the cost of construction, but also to obtain new facilities in the city. Despite the large number of industrial buildings that have lost their effectiveness and relevance, as well as a significant investor interest in these objects, the scope of redevelopment in the construction remains unexplored. Analysis researches on the topic. The problem of reconstruction of industrial buildings considered in Topchy D. [3], Travin V. [9], as well as in the work of other scientists. However, there are no rules in regulatory documents and system studies for improving the organization of the reconstruction of buildings at realigning. The purpose of this work is the development an algorithm of actions for selection of effective organizational decisions at the planning stage of a reprofiling project of industrial buildings. The proposed algorithm allows you to select an effective organizational and technological solution for the re-profiling of industrial buildings, taking into account features of the building, its location, its state of structures and existing restrictions. The most effective organizational solution allows realize the reprofiling project of an industrial building in the most possible short terms and with the lowest possible use of material resources, taking into account the available features and restrictions. Conclusion. Each object has a number of unique features that necessary for considering at choosing an effective reprofiling variant. The developed algorithm for selecting effective decisions of reprofiling buildings is recommended for use in accordance with for the purpose of logical and errors excluding the final result.

Statement of the problem. Health and human performance largely determined by the conditions of climate and air quality in residential, administrative and residential and public buildings. At that, in turn, is influenced by the external environment and the climate, and the geometric dimensions of the room, and thermal performance building envelopes, and the location of the premises (Orientation), and many other factors. The result is the formation of complex systems, which control decision-making in conditions of multifactor [1]. In hygienic purposes it is necessary to strive to create the best indoor microclimate conditions, regardless of changes in the factors that affect the climate in residential, administrative and residential and public buildings. Develop systems to ensure the necessary microclimate parameters – it is a complex and important task, which will depend entirely comfortable and cozy environment for the person. The problem of the present time, there is a steady increase in the energy consumption of these systems, due to the rise in price of non-renewable energy sources, and our job is, to simulate the work of software systems necessary microclimate for the changes in the factors that affect it and to minimize the use of non-renewable energy sources. Analysis of recent research and publications. Domestic and foreign hygienists [2, 3, 4] to establish a connection between the climate in the room and in the workplace and the state of human health. Formation of the indoor climate of residential, administrative and residential and public buildings is influenced by many factors that have already noted earlier [5, 6]. Study of the processes of influence of various factors on human health is of great complexity. If we consider each process separately, and in this case they are not currently amenable to theoretical description clearer. To simulate the effect of these factors studies were conducted, which showed that, with sufficient accuracy manage experimentally investigate the electrical field in the liquid conducting medium as an analog of the thermal field [7, 8]. Isolation of previously solved problems. Known methods for modeling are approximate and have drawbacks that reduce the accuracy and limited scope. Therefore, one way to obtain effective thermal solutions is a simulation of thermal processes with further analysis of the results. It was suggested that the thermal field in the room to simulate electric field in the plating bath, and the analog heat flux between surfaces of any room space assumed current density between the surfaces of the model. The smaller the distance between the selected measurement points, the more accurate will be recreated actual picture patterns in the electric field and hence the thermal field in the room [7, 8]. But this method does not enable to take into account all the possible variations that affect the formation of indoor climate. Working with models that use an electric field to the heat radiation transfer simulations showed a significant labor input in the input model of the initial information and the removal of the simulation results. Objectives. Describe the behavior of the system (the influence of the microclimate of the environment and the geometric dimensions of the room, and thermal performance building envelopes, and the location of the premises (Orientation), and many other factors in the indoor climate of buildings), to build theories and hypotheses that could explain the behavior, which It will be observed to use the theory for predicting the future behavior of the system, that is, those factors that can be caused by a change in the system or change the way of its functioning. Conclusions. The proposed approach to addressing the issues raised will reveal the point of interaction between the different elements and factors that affect the indoor climate of buildings for different purposes. In the future, use the simulation method to study changes in microclimate in the buildings of different functions when you change the factors that affect it. This will create a system of automatic control of technological space heating and cooling processes, which will adapt to the changes in the factors that affect the indoor climate of buildings for different purposes.

Raising of problem. The problem of quality of atmospheric air takes a special place among problems of protection of a surrounding environment. It is caused first of all by vital necessity of atmospheric air for all alive on the Earth, influence of a condition of an atmosphere on global climatic processes and biosphere as a whole due to huge mobility of air weights with which harmful impurity can be transferred. These questions for industrial regions where the level of anthropogenous influence has reached critical size are especially actual. The Dnepropetrovsk area concerns to such regions also. By development of scripts of development of such regions and their territorial components there is a necessity for definition of possible consequences of anthropogenous processes, which occur (or can occur) in atmospheric air. It demands strengthening прогнозных functions of ecological monitoring, in particular on atmospheric air, at planning and building of territories, at a choice of the optimum script of town-planning. Purpose. To improve a subsystem of an estimation and the forecast of a condition of atmospheric air on an example of system of ecological monitoring «Pridneprov'e» the Dnepropetrovsk area by means of introduction of a complex of the mathematical models focused on large industrial region which will allow at presence of criteria and parameters to receive as statistical (for the short-term forecast during steady atmospheric processes), and dynamic estimations of a condition of atmospheric air, the forecast of changes of parameters of atmospheric air and distribution of polluting substances, and also their influence on an environment and the person. Conclusion. The offered approach allows to consider complex parameters of steady development, territorial, branch, social, economic and ecological, time aspects, opportunities of atmospheric air as a polyresource, provides the forecast and an estimation of a condition of atmospheric air in system of regional ecological monitoring at a choice and realization of strategy of steady ecological and economic development of territory.
