Who Can be CDO in Construction?
Authors: Ignatova E
Published: March 2021

Digitalization of the economy requires new specialists for data-based management called Chief Data Officers (CDOs). It is noted that digitalization is no longer the prerogative of a single IT industry. The digital transformation of the construction industry introduces general processes of digitalization, but it has its own peculiarities. The technology of building information modeling (BIM) is being implemented by construction sector companies. The specialist who leads the implementation of information modeling technologies in the organization is a BIM manager. A BIM manager, as well as CDO, must have competencies in the field of IT, management, and data applications. Analysis of the functions and competencies of a BIM manager allows us to conclude that he can become a CDO for managing the organization’s production activities based on BIM data.

Authors: Chuvashlova M , Danilochkina N , Semenyutova I
Published: March 2021

Relevance of this study derives from the fact that state-owned companies need new approaches to improving performance of their management systems and maintaining the appropriate balance between external and internal environments. To a greater extent than their counterparts from the private sector, such companies are keen to choose and rationalize specific forms of management control which enable them to retain financial stability and competitive edge in the global market, and to create value through the realization of additional competitive advantages by proactively affecting value factors.

The intent of this work is to develop a framework and to validate kinesthetic controlling methodology for state-owned aircraft construction companies that would enable purpose-oriented management actions on a company’s competitive position in the global market. The information contained in this work will be of practical value for both top management and executives at different levels across organization structures of production companies and other entities, both in aerospace and other sectors.

As a result of the research conducted, the function-and-value component of kinesthetic controlling model was defined. The model is based on Value Management Concept which includes profit-based and comparative approaches to business value assessment, highlighting controlling indicators at operational and strategic levels, which refer to competence areas of responsibility of different management subjects, considering the possibility and admissibility of reacting to the revealed deviations from critical values and coordination of management actions as they affect strategic priorities of business development in a sustainable way.

Authors: Vasileva A G , Ivashina N S , Kuznetsova N V
Published: March 2021

The priority of the balanced socio-economic development of single-industry towns for the economic policy of the Russian Federation explains the active usage by the Government of the Russian Federation of mechanisms for adapting single-industry towns to changes in the external environment, involving large-scale and systematic federal resource support, i.e. government programs. However, often the planned values of indicators of state programs for the socio-economic development of single-industry towns are formally formulated and do not allow judging the degree of achievement of their goals. The listed circumstances determine the need for scientific research, within the framework of which a retrospective analysis of the efficiency of state programs to support their development was carried out using the example of single-industry towns of the Chelyabinsk oblast of the Russian Federation.

The article presents the results of the study of target indicators system that allow to carry out a retrospective analysis of the efficiency of state programs to support the development of single-industry towns, and the results of testing the identified criteria for the program "Integrated development of single-industry towns in the Chelyabinsk oblast".
Public-Private Partnership and Resolving the Societal Crisis Caused by the COVID-19 Pandemic
Authors: Vaslavskaya I Yu , Vaslavskiy Y I
Published: March 2021

COVID-19 triggered several crises, one of which arose in the social sphere. Societal crisis manifested itself in the growing distrust of ordinary citizens to the state, in the negative consequences for them of the forced restriction of social communication due to the lockdown, and in the understanding of the discrepancy between their own individual values and the generally accepted norms of behavior in society, specified by formal institutions. These social problems have only increased the quality of uncertainty of the post-coronavirus pandemic reality. A rise in uncertainty will lead to increased precautionary savings among households and delayed business investment. Against this background, social polarization in society, growing unemployment, poverty and impoverishment of citizens have further increased their negative attitude towards the state and society as a whole. As a result, overcoming the consequences of the societal crisis in national communities has become almost the highest priority along with the problem of epinomics. Its solution lies in the gradual restoration of partnerships between society, firms, citizens and the state. The most important place is occupied by public-private partnership in any public sector, including socially significant infrastructure projects. However, significant progress in this area is unambiguously due to serious adjustments that the state must make to formal institutions that ensure an equal partnership between the state and the business. At the same time, the specification by formal institutions of expert functions of the state and increasing the importance of private investment in the project will allow using the partnership between the state and private business as a platform for testing various forms of inclusiveness of public and private participation, aimed at restoring public confidence and societal integrity of society.

System for Uncertainty Factors Accounting When Optimizing and Choosing Effective Options for Network Work Schedules on a Dynamic Model with Dead-End Controls
Authors: Korneenko V P , Nazyuta S V , Chursin A A
Published: March 2021

This article proposes accounting for uncertainty factors in a dynamic optimization model. Accounting for uncertainty factors in equipment performance is represented by a decreasing piecewise-constant function, the domain of which is the expert ordinal measurement scale. The basis of the optimization of the execution time on the example of creating a helicopter technology is the dead-end control method which refers to such an admissible Boolean control in which the replacement of an arbitrary zero component by one leads to a violation of the resource constraint. To ensure stable work of a manufacturer, several options of network schedules are usually calculated based on various initial data. The final choice of the effective option is made according to a vector criterion, which can include the time of completion of a complex of works, the degree of intensity of a plant’s work plans, the uniformity of the equipment load (work teams), etc.

Authors: Osennyaya A V , Khakhuk B A , Gura D A , Petel N I
Published: March 2021

Absence of databases compiled during the real estate market analysis poses a substantial problem and questions the integrity and validity of evaluation appraisals. This study is relevant due to its formal approach towards analyzing the real estate market, the necessity to accumulate relevant data and price factors, and taking into consideration the objectives of the appraisal. Use of insufficient or irrelevant data from reports on market/cadastral value poses a significant problem, which hinders practical implementation of modern economic processes and influences purchase and sales prices of real estate, as well as its taxation during cadastral appraisal.

The subject of this research is the real estate market of Krasnodar. The object of this research is the economic interaction taking place during construction, turnover, and development of real estate property. The authors have divided the territory of Krasnodar into zones and selected the most economically developed neighborhoods. These neighborhoods constituted the material of this study. The authors have also determined the pricing factors and their quantitative features. During this study, a database which may be used for real estate property appraisal has been created.

Authors: Mitrofanova E , Lovcheva M , Pritolyuk A
Published: March 2021

However, the low effectiveness of the procedures, which regulate socio-economic relations, such as underestimation of the importance of a problem such as the need for their restructuration lead to a necessity in increased attention throughout the economic entities of the real sector of the economy. The urgency of this research problem can be determined by the lack of development of the tools which in turn lead to the development and implementation of personnel policy, aimed at improving the socio-labor relations by making sure to provide sustainable employment inside the organization and effective regulation of the internal labor market. The article demonstrates that personnel policy is not only the main element of socio-labor relations but also a key part for personnel management decisions, since it predetermines the receipt of an overall positive synergetic effect. In this regard, it has been demonstrated that developing organizations which have based their policies on active innovation and strategic processes both internally and externally are characterized for using multiple personnel policies simultaneously resulting to distortions within the organization, which in turn negatively affect the performance of the organization as a whole. It is substantiated that personnel policy should not be regarded as an obligatory formal document, but more as a strategically significant decision for personnel management, which in turn could affect not only the destiny of the organization but also their balance of power among the competitive environment both positively or negatively depending on how correctly it was set.

Authors: Fedonin O N , Simkin A Z , Mozhaeva T P , Proskurin A S
Published: March 2021

Modern development of additional educational services makes it necessary for educational organizations that provide such services to use tools to guarantee the quality of education. The international and domestic scientific communities in the field of additional professional education (APE) have developed and successfully introduced into educational practice a three-level trajectory of confirming the quality of education implemented by educational organizations: institutional, program and qualification trajectories. An educational organization that operates in the field of additional professional education can choose any option to confirm the quality of its activities.

However, practice shows that for a higher education institution where additional professional training is a subsystem of its quality management system (QMS), the institutional trajectory, which provides for the development, implementation and confirmation of compliance with the QMS of APE, seems to be the most important. Therefore, it is proposed to adapt the standard model of quality system (ISO 9000 & ENQA) to the specifics of additional professional education. This standard model has a modular and hierarchical structure that allows to integrate APE QMS into QMS of a higher education institution quite easily.

The approach proposed in the paper to guarantee the quality of additional professional education implemented by higher education institutions, based on APE QMS, and having a modular and hierarchical model of the quality system (ISO 9000 & ENQA), will ensure the quality of training of students of professional educational programs.
Taxation Instruments for the Support of Research and Advanced Development Expenses in the Manufacturing Sector of the Economy
Authors: Akhmadeev R G , Bykanova O A
Published: March 2021

The goal of this research is studying the results achieved by using the existing taxation instruments regulating the creation of R&D expenses during the profits tax calculation and payment in the manufacturing sector of the economy of the Russian Federation. The main methods of this research are the analysis and the generalization of regulatory documents, as well as the mathematical representation based on the extrapolation of empiric data on the structure of R&D expenses incurred within 2012-2018 on the profit tax base. In terms of expense tracking, Russian tax legislation prescribes complicated procedures for R&D expenses accounting taking into consideration such limitation as using a minimum of 75% of the labor costs. The mechanism of fiscal expansion for the innovative activities in terms of R&D is separate from the methods of innovation process implementation, including the product life cycle phases and innovation process stages. Due to this, it is important to treat manufacturing enterprises as a separate category, because their operations are innovation-active. In practice, we suggest expanding the existing list of innovative activities in strategic areas of the country’s economic safety in order to increase the rates of high-end technology introduction in manufacturing.

Authors: Piskaeva A I , Babich O O
Published: March 2021

Throughout the world, along with the benefits that poultry farming brings to the economy of each individual country, there is a large-scale problem of such byproduct of its activity as feathers. In addition, 91% of them consist of a very valuable protein source with β-keratin. Keratin itself is very poorly decomposed and further disposed component. It makes up one of the components of feathers, the part of vertebrate skin.

There is a growing preference for cost-effective and ecologically friendly poultry waste management ways. And it is the keratinase enzyme, obtained as a result of the bacteria activities, that shows great potential in this area. The selection, identification and improvement of the activities of such species of bacteria which could decompose the chicken feathers is the subject of ongoing research. About 89% provided chicken feathers were disposed (in other words, utilized) by bacteria in 2 days at temperature of 37° C. Full disposal took place after 53 hours. This study provides new results on the activities of microorganisms in the sphere of feather composting, and could also serve as an instruction for improving the work of the poultry industry in the management of keratin waste.

Authors: Stepanova L P , Yelizarov N A , Pisareva A V
Published: March 2021

The article presents studies on establishing the influence of anthropogenic impacts on alluvial soils of agricultural lands. To solve the problem set, tasks were determined to estimate the degree of damage caused to soils of agricultural lands as a result of the soil humus layer loss or closure. These tasks included establishing the degree of alteration in soil fertility indicators for agricultural lands in regard to pH volume; organic matter content; degree of provision with K2O and P2O5 accessible forms as a result of violating technology of the damaged land stripping and reclamation. Nature of changes in granulometric (grain) and micro-aggregate soil composition is demonstrated. Study objects included agricultural land territories with soil samples of alluvial granular soil taken at the depth of 0-5 cm and 5-20 cm. Necessity is demonstrated to study in detail the agroecological assessment of land use systems and the development of differentiated measures ensuring reproduction of soil fertility, crop growth and territory ecological sustainability. Negative processes are manifested to a varying degree on agricultural land in most administrative regions of Russia including agricultural land in the Orel Region, which requires creation of the ecologically sustainable land use system. Since transformation of compounds entering the ecological system primarily occurs in the soil, which acts as a filter and as the factor of transformation and accumulation of the entering substances, agrobiological features of soil composition and properties make it extremely sensitive to anthropogenic impact. As a result of scientific research, it was revealed that the studied area experienced a decrease in soil fertility main indicators of the alluvial soils and destruction (deterioration) of the fertile soil layer as a result of exposure to anthropogenic influence. Rates of decrease in the organic matter content in soil layer as a result of the soil humus layer damage are shown. Significant fluctuations in the amount of exchangeable potassium in the soils of anthropogenically damaged agricultural lands are established. Degree of decrease in the amount of available phosphorus in soils without humus layer is revealed. Significant alteration in the granulometric (grain) composition of the damaged land soil is proved.

Published: March 2021

The economic indicators of the development of the economy of the countries of the world and the presence of the ecology of the environment are significantly influenced by the points of location of power plants in large cities. In modern conditions, these points are recommended to be set taking into account the presence of cost factors in each large city. The use of these features allows you to minimize the emission of gases into the city. On the territory of the continent of Eurasia, there is a cargo point located in Kuzbass, in Russia. From this main loading point for coal on the railway network, loaded wagon flows are sent both in the western and eastern directions. The presence of this cargo terminal on the continent will have a significant impact on the rational location of CHP in large cities. The most rational will be the location of CHPPs, which will be located on the territory of large cities and located separately: both for the western and eastern parts of the continent. When energy streams move from the cargo-handling point, CHPs should be located at the entrance to the city. In the western part of the continent of Eurasia, it is more efficient to locate CHP in the eastern part of large cities. For the eastern part of the continent, power plants should be located on the outskirts in the western part of large cities behind the cargo-handling point.

Published: March 2021

The spread of the dangerous Covid-19 infection caused by the SARS-CoV-2 coronavirus since the end of 2019 has become a big challenge for both the world and Russian society. Thus, on January 30, 2020, the world health organization recognized the spread of a new infection as a public health emergency of international significance. On March 11, 2020, the same organization stated that the outbreak had become a pandemic. Currently, the role of social and environmental factors (which determine the spread of many environmentally-related diseases) in the spread of coronavirus infection in the population is not fully understood. The spread of Covid-19 infection in Russia can be divided into 3 stages. Stage 1 (31.01.2020-01.04.2020) - primary distribution. At this stage, the infection occurred mainly of Russian citizens visiting other countries. Stage 2 (1.04.2020-12.05.2020) - active distribution within the country. By the end of this stage, the maximum spread of infection is recorded. Stage 3 (12.05.2020-present) - gradual decline in the appearance of new cases of coronavirus infection. To assess the specific contribution of social and environmental conditions to the spread of coronavirus infection, data from the Federal information Fund for social and hygienic monitoring of the Federal center for hygiene and epidemiology of Rospotrebnadzor on indicators of financial security of citizens, quality of health care and sanitary conditions were analyzed. Studies have shown that at the first stages, a significant contribution to the spread of infection is made by the financial security of the population. The specific contribution of the quality of medical care, which is widely differentiated within the regions of Russia, affects only the third stage of the spread of coronavirus infection. Environmental and hygiene indicators make a weak contribution to the spread of Covid-19 at all three stages of the epidemic.

Authors: Kotelnikov A V , Pyurbeeva Z Y , Kotelnikova S V
Published: March 2021

In the Astrakhan Region (Russia) on the bank of the Kizan River, which is a tributary of the Volga River, there are two oil sludge collectors, called “Sokolov pits”. They were created in the early twentieth century and now they are a major threat to the ecosystem of the delta river Volga. In this regard, it is topical to conduct studies to assess their environmental safety. The content of petroleum products and the biotoxicity of the soil in the territory of oil sludge accumulators are investigated. The seeds’ germination of watercress (Lepidium sativum) of plants was analyzed. During the study period (2017-2019) the dynamics of phytotoxicity of soils taken from the surface of oil sludge accumulators “Sokolov pits” was of an oscillatory nature. At the same time, the large phytotoxicity of the soil was abolished in 2017. On the territory of oil sludge accumulators “Sokolov pits” the greatest toxicity is the soil from the edge of the oil fields facing the river bank, the smallest is the soil from the edge, far from the shore. Thus, it can be noted a slight positive effect of the reclamation activities, the negative impact on the soil is not eliminated.

Published: March 2021

The article provides a brief analysis of technological solutions for preparing rough feeds for feeding with an emphasis on the existing shortcomings in the implementation of the technological process, taking into account its technical support. There have been proposed and considered two technical and technological schemes for the preparation of rough feeds, the effectiveness of which is aimed at their rational use as a factor of low-waste technology and reducing the influence of a secondary factor when performing the considered technological process. The pollution of the airspace of the livestock building and the skin of animals with dust particles, including small particles of feed and microflora of dry food, can be considered as the very factor affecting the environmental safety of the internal space of the livestock building and indirectly the quality of products (milk). This is confirmed by the presented research results for separate technological operations.

Authors: Krupko A E , Rogozina R E , Derevyagina M V
Published: March 2021

The purpose of the work is to identify the factors, features and problems of water use in the Central Black Earth Region. The Central Black Earth Region is characterized by longterm degradation of water resources, irrational water use, a low level of water purification, a high degree of pollution of water bodies, which requires a deep analysis of factors and trends in the development of the area’s natural resources. To achieve this goal, comparative, structural, statistical and analytical research methods were used. The information provided in the open official publications of the state statistics of the country and regions was used, in particular, the State Report “On the state and use of water resources of the Russian Federation in 2018” and reports on the state and protection of the environment of the Central Black Earth Region in 2018. In the course of the work, the data is systematized, structured, analyzed and summarized. The quality of water resources in the Central Black Earth Region is affected by the deterioration of the natural environment, including destruction of soils, a decrease in forest cover, and water and air pollution. Analysis of the development of water use shows us the complex ecological situation with the water resources of the region, characterized by a decrease in their volume. There are no rivers and reservoirs with “roughly clean” water in the Central Black Earth Region, water bodies of the 3rd category prevail, and there are even reservoirs of the 4th category of pollution. The water regime is deteriorating, fauna and flora are degrading. Taking into account the trends and features of modern nature management, on the basis of our work, we can conclude that the most effective direction of greening water use in the Central Black Earth Region is to reduce water consumption, purification of all types of runoff, optimization and afforestation of water protection zones.

Published: March 2021

This paper described the development and application of a nitrifying bacteria sensor to monitor water toxicity. Four strains of bacteria with high efficiency nitrification, designated as F1, F4, Y2 and Z1, were isolated from fish pond sediment, and identified as Rhodococcus sp. (F1 and F4), Pseudomonas sp. (Y2) and Micrococcus sp. (Z1). The four bacterial strains were tested for their nitrifying capabilities. The results showed that the nitrifying rate of F1, F4, Y2 and Z1 reached 3.51, 3.43, 3.46, 3.52 mg/L·d respectively. The four strains were further cultivated for 21 days to investigate the effects of temperature, pH and inoculation amount on their NH4
+-N degradation ability. The cultivation showed that the four strains possessed optimal NH4
+-N degradation rate when temperature was 35?, pH value was 8.5, and inoculation amount was 30%. Furthermore, the carrier optimization test demonstrated that the nitrobacteria film prepared using 16% PVA, 1.2% SA, 2% NaNO3 and 75% CaCl2 had the best performance of toxicity detection. These results suggested that the nitrobacteria biosensor designed in this study was sensible and suitable for detecting water toxicity.

Published: March 2021

Salidroside is verified to have tumor inhibitory effects. Nevertheless, the mechanisms are not clarified. The research aims to explore the tumor inhibitory mechanisms of salidroside on gastric carcinoma. The tumor inhibitory effects were examined by the cell viability assay. Flow cytometric analysis was adopted to estimate the cancer cells apoptosis. The expressions of differentiated embryo-chondrocyte expressed gene 1 (DEC1), hypoxia-inducible factor-1α (HIF-1α) and signal transducer and activator of transcription 3 (STAT3) in carcinoma cells were measured by immunohistochemistry assay. Salidroside displayed definite cytotoxicity effects on gastric carcinoma cells in a dose and time dependent manner. Apoptotic percent in carcinoma cells treated with salidroside were significantly increased (P < 0.05). The migrations of cancer cells were suppressed with the increasing doses of salidroside. The expressions of HIF-1α, DEC1 and STAT3 in cancer cells with salidroside treatment were down-regulated. The findings suggested that salidroside suppressed the growth of gastric cancer cells by eliciting the cancer cells apoptosis and lowing the expressions of HIF-1α, DEC1 and STAT3 signal molecules.

Large volumes of construction waste have been produced with the rapid development of subway projects in Shenzhen, China. To solve the problems of difficult storage and low resource utilization of the subway construction waste, Shenzhen government has required the contractors to reduce the subway construction waste by onsite and offsite treatment processes since May 2019. This study introduces an offsite treatment process of the subway construction waste in Shenzhen. Some improvement measures such as replacing drum-type sand screening and settling tanks with centrifugal solid-liquid separation equipment and inclined plate sedimentation equipment are proposed to recycle fine sand and heighten treatment efficiency.

In order to study the spatial variability and influencing factors of heavy metals contents in five mangroves in South China, surface sediments and plant canopy new leaves of mangroves were sampled to determine Cr, Ni, Cu, Zn, Pb contents. Moreover, the corresponding pollution load index of sediments and bioconcentration factors of leaves were evaluated. Meanwhile, the physical and chemical properties, organic carbon and nitrogen of surface sediments and new leaves were measured. It was found that the average content of heavy metals in the surface sediments of Futian Reserve was the highest with a pollution load index of 2.61, classified as strongly polluted. The particle size distribution of the five sites was mainly silt-sand, and the pH was slightly acidic. Multivariate analysis of variance indicated that both sampling locations and vegetation types had significant influences on heavy metal contents in surface sediments and leaves as well as bioconcentration factors of leaves. In sum, natural factors such as plant species and organic matter contents significantly influence the metal contents and translocation in mangrove forests. However, in strongly polluted areas anthropogenic factors compromise the natural effects and play the major role in metal distribution.

Using remote sensing images to extract the shoreline is an important means of studying coastlines. In this paper, we propose a semi-automatic coastline extraction method based on the coastline type that uses region segmentation and edge detection image processing. Based on selected Landsat 4-5 TM and Landsat 8 OLI_TIRS satellite images of Chongming Island from 1985 to 2017, we find that the point control method, neighborhood marking method, and targeted selection based on different shoreline types significantly improve the calculation efficiency, have good adaptability, and produce highly accurate shoreline extraction.

Published: March 2021

Based on the best track data set of tropical cyclones and ENSO index, the influence of two kinds of ENSO events on tropical cyclones in the Northwest Pacific Ocean is discussed based on the El Niño / La Niña event discrimination method recently issued by China Meteorological Administration. The results show that ENSO events have an important impact on the TC activity in the Northwest Pacific. The frequency of TC formation in La Niña year is more than that in El Niño year, and the duration and ACE of TC in El Niño year are greater than those in La Niña year. From the comparison of TC activities at different levels, the impact of ENSO events on high-level TC (STY and SuperTY) is greater than that of low-level TC. On the whole, the TC in the Northwest Pacific is greatly affected by the CP-ENSO event, and the high-level TC (SuperTY) is most affected by the EP-ENSO event. In terms of the origin location, the differences of the impact of the two ENSO events on TC origins of different levels are mainly reflected in the differences between the northern and southern South China Sea, and the differences between the southeast and Northwest Pacific.

Birds keeping, especially songbirds, has been considered as one of the major drivers that lead to species extinction in Indonesia. The demand for songbirds either for songbird’s competition or to be enjoyed at home is considerably high, especially in Java. As the native Javan population has been depleted due to habitat conversion and excessive trapping, the supply of songbirds is provided by other islands in Indonesia such as Sumatera and Kalimantan. We conducted long term monitoring of songbird’s trade on Jambi. Data on bird’s trade was obtained by examining the transaction records from wholesalers from the period of 2016 – 2020. The results showed that there were shifting in species target especially after 2018 due to implementation of new regulation on protected species. However, the total number remains high. The trade comparison for the same period between trade records in 2016 and 2020 demonstrated the reduction in the number of species from around 32 species to 25 species, however, the total volume of traded birds is higher in 2020 which is 20.600 compare to 7.198 during the first sixth months. Considering the pandemic situation, the songbirds trade activities is seemingly not affected especially for the distribution chain from hunter to wholesalers.
