Knowledge management in the construction industry has become an element of transition between traditional processes and the current needs demanded by technological change. This research reviews the updated scientific contributions of knowledge management in construction, as well as its influence. The results come from a bibliometric study, elaborating a quantitative and qualitative analysis of the current state. The research method was divided into the following stages: preliminary approach to the bibliography, establishment of search strategies, selection and classification of articles, quantitative analysis and discussion of relevant articles. Three main factors were identified: use and exploitation of knowledge, knowledge transfer, and information technologies; five complementary facets were also identified: culture, innovation, quality, knowledge generation and human factors. The results reaffirm the importance of the use and exploitation of knowledge, in addition to increasing attention to the transfer and technology of information. However, the generation of knowledge has declined because the sector still does not report the results of applying knowledge, and this underlines the need for the future study of strategies to transform tacit knowledge into explicit knowledge.

The relevance of the study. The traditional idea of a cadence as a primarily harmonic phenomenon does not completely correspond to some musical styles, including Renaissance and early Baroque. Revealing the polyphonic essence of cadences in vocal works of the Renaissance, which is the aim of the article, allows deeper understanding peculiarities of musical thinking of that period. Scientific novelty. The historical approach to the analysis of cadences is quite common in foreign musicological works; this approach is still new for Ukrainian musicology. The research material is also new: the cycle of motets by G. Palestrina on the text of “Song of Songs” was unfairly ignored by Ukrainian and foreign scholars. Thus, the study is relevant both in relation to the method and in relation to the musical material involved in its approbation. The purpose of the article is to show the specifics of cadences in the style of a strict counterpoint using the motets from the cycle “Canticum Canticorum” by G. Palestrina, to reveal the role of cadences in the modal and compositional processes of a Renaissance work. Research methods. The study systematizes the data obtained as a result of the analysis of the cadences of G. Palestrina’s motets, thus, the main research method is inductive. The main results and conclusions of the study. Cadences in vocal polyphony of the Renaissance have a polymelodic nature, which is realized by combining typical melodic turns (clausulae) in different voices. The clausulae order in the voices and their completeness degree are effective criteria for the classification of cadences (e. g. the classification by E. Rotem). Cadences in which the main clausulae are presented in full (i. e. contain ultima and penultima) are strong. Cadences in which one or more clausulae are incomplete are weak. The role of strong and weak cadences in the composition is different: strong cadences are placed at the nodal points of the piece, they have a dividing function; weak cadences are placed in the middle of the text line and they have a connecting function. Strong cadences are the norm, while weak ones violate the norm, revealing the author’s ingenuity. There are a few ways to weaken the cadence: replacing the ultima with a pause or a different sound, distributing the clausula between several voices, extending the melodic line of one of the cadence voices, etc. Weak cadences significantly outnumber strong cadences. In the Dorian motets from the cycle “Song of Songs” by G. Palestrina weak cadences play an important role in the formation of the mode within the sound scale, as well as in revealing the meaning of the verbal text.

The article analyzes the current state of the irrigation and drainage systems of the Ryazan region. It is shown that the lack of technical operation of the drainage network led to its failure and failure to perform its functions. Irrigation, in spite of the fact that it gives stability in the years of droughts due to aging and the dismantling of machinery and equipment is not carried out. It is shown that for the reconstruction and / or modernization of irrigation and drainage systems it is necessary on the basis of inventory to determine the environmentally optimal and economically viable systems, their parts and structures that require rehabilitation, reconstruction and / or modernization. The decision to reconstruct may include not only the ameliorative system as a whole, but also some part of it, for example, a canal, pipeline or a separate hydraulic structure, taking into account the justification of economic feasibility. In dry periods, for the Meshcherskaya lowland and areas with peat soils, it is necessary to provide for land-reclamation systems for dual regulation of soil moisture, which reduces the possibility of peat ignition and the spread of fire. It should be borne in mind that the reconstruction of land-reclamation systems has its specific features, which include: socio-economic (increasing the productivity of agricultural land, obtaining additional income, creating modern infrastructure, increasing employment, living conditions, labor, etc.) ; ecological (creation of cultural landscapes, ensuring their ecological sustainability, prevention of land degradation processes, improvement of recreational conditions, elimination of waterlogging, flooding, salinization, erosion, etc.). Reclamation activities are carried out in compliance with the requirements of land, water, forestry legislation of the Russian Federation, as well as the legislation of the Russian Federation on the protection of the environment, on the subsurface, on the plant world and on the animal world.

The article is devoted doctrinal issues of environmental and economic effectiveness of use land in conditions of infringement of institutional transformations. The modern approaches to the definition of content of ecological and economic effectiveness of land use are analyzed. It is established that the overwhelming majority of domestic researchers interpret this notion regarding the use of agricultural land or farm land. It is proved that such an approach is justified, taking into account the structure of the land fund of Ukraine. However, this reduces other goals of the land user and functions of the land. It is proposed to investigate the category of ecological and economic effectiveness of land use in accordance with the provisions of the ecological economics, social welfare theory, and concept of total economic value. Based on the classification of land functions, the criteria of selection material content and social form of ecological and economic effectiveness of land use are determined.

Works on protective afforestation are carried out in order to protect agricultural land from degradation processes, as well as to improve the microclimate of land. The research purpose is to study the bioproductivity and environmental role of Robinia pseudoacacia L. forest shelterbelts in the conditions of the Kuban lowland. The approved and generally accepted methods of forest valuation, forest land reclamation, botany, and mathematical statistics were applied. Plantings were created according to the standard technology for the steppe zone of the Russian Federation. The area of forest shelterbelts is 62.4 ths ha, including 5 % of the young growth (I state class), 80 % of middle-aged forest plantings (II state class), 10 % of maturing plantings (II state class), 5 % of mature and overmature plantings (III state class). Living ground cover is formed by the following species: Koeleria pyramidata L., Poa pratensis L., Festuca pratensis H., Elytrígia repens L., Dactylis glomerata L., and Phlum pratense L. Aboveground phytomass is 100–300 g/m2; height is 25–32 cm. Plantings are characterized by the quality classes: young growth – I and II; middle-aged and maturing – III; mature and overmature – IV. At the age of natural maturity (70 years), the Robinia trunk reaches the average height of 15.1 m with the average diameter of 22.1 cm. The total stock of wood reaches 18, (ths m3), including (ths m3): young growth – 68 (ths m3); middleaged plantings – 14,871 (ths m3); maturing plantings – 2,187 (ths m3); mature and overmature plantings – 1,314 (ths m3). Aboveground phytomass in young growth is 20.2 t/ha; in mature and overmature plantings it is 391.2 t/ha. In the region it is estimated at 17,070 ths t, including (ths t): young growth – 64; middle-aged plantings – 13,753; maturing plantings – 2,032; mature and overmature plantings – 1,221. The share of stem mass reaches 84.5–80.8 %; woody greenery – 4.2–1.5 %; branches – 11.3–17.7 %. Recalculation coefficients of the stock into aboveground phytomass are the following for: young growth – 0.936; mature and overmature forest shelterbelts – 0.929. Phytosaturation of forest shelterbelts varies within 0.314–2.474 kg/m3. Forest shelterbelts have accumulated 8,534 ths t of carbon, which is estimated at 145.1 mln dollars. The sphere of application of the research results is the Krasnodar Krai forestry, which is recommended to create an additional 60 ths ha of forest shelterbelts, which will provide a normative protective forest cover of arable land of 5 % and annual carbon sequestration up to 3.4 t/ha.

There are many studies which implement and assess existing measurement manners and document the progress of entities towards the circular economy (CE) at various levels, or present or propose new possibilities of measurement. The majority of them refer to the micro level. The aim of this paper is to conduct a multidimensional comparative analysis of the implementation of circular economy by EU countries. After an in-depth critical analysis of the literature, CE indicators which were proposed by the European Commission were adopted as a basis. Owing to the research population-Member States of the European Union (EU-28), focusing on the said indicators was declared reasonable in all aspects. The classification of EU countries according to the level of their advancement in the concept of CE was adopted as a main research task. In order to do so, a relevant index of development of circular economy was created (IDCE). This will allow us, inter alia, to trace changes in the spatial differentiation of advancement of the EU countries in implementing CE over the years, to identify CE implementation leaders as well as countries particularly delayed in this regard. The comparative analysis was conducted by means of statistical methods. On the basis of the analyses, it was concluded that among all EU countries, those of the old EU are the most advanced in terms of CE. The analysis confirmed significant rising trends for IDCE only in the case of Belgium and The Netherlands.
