Published: November 2021

The assessment of current production activities is carried out on the example of specialized construction and installation management with the help of turnover indicators as well as the level of efficiency of use of own and borrowed funds by the enterprise was determined.
Indicators of this group characterize the results and efficiency of the current main activity of the enterprise, such analysis can be carried out both at the qualitative level and with the help of quantitative criteria.
The main ones are production indicators, return on assets and turnover indicators. These indicators are of great importance for assessing the financial condition of the enterprise, because the speed of turnover, i.e. the speed of their conversion into cash, directly affects the solvency. The results of the calculation of the rate of return indicate that this fact (decrease in the turnover of fixed assets) may be associated with aging and wear of production equipment, i.e. we can say that the technical level of fixed assets of the object is low.
The coefficient of sustainability of economic growth shows the average rate at which the company can develop further, without changing the already established relationship between different sources of funding. Summarizing the comparative data, we can say that if the management of the enterprise intends to increase its production capacity in order to increase production, it is necessary to change the financial policy. The results of calculations allow to show that at the analyzed enterprise there was a significant increase in the full production cycle and turnover as a whole. The duration of the operating cycle increased by more than 1.2 times and the duration of the financial cycle by almost 2 times. This was negatively affected by the factor of a significant slowdown in the turnover of inventories. Increasing the full production cycle in the future may cause negative trends in the enterprise as a whole, because this factor will primarily affect the amount of profit, which will affect the efficiency of production. The company activities to reduce the amount of net profit was influenced primarily by the acquisition of inventories, low-value perishable items and fixed assets, as well as repayment of accounts payable and payment of penalties.
The period of turnover of the most liquid assets during the year varied from 0.04 to 17.5 days. The average chronological value in the period of saving money in the accounts of the enterprise was 7.5 days. This fact indicates that the company, despite the apparent well-being, is experiencing a serious shortage of funds. They were enough for a little over a week. Thus, with the help of analysis of economic indicators, you can describe the general condition of the company and the possibilities of its operation and development

Published: November 2021

The article highlights the theoretical approaches to the essence of the concept of "budgeting" as a tool for managing economic activity of the enterprise. Based on the study of interpretations of the "budgeting" concept, a comparison of opinions of different scientists-researchers of this economic category is generalized and formed. The role of budgeting and opportunities for effective management of economic activity of the enterprise are revealed. The principles on which the budgeting system is based are analyzed and supplemented by their own, which include: optimality; unity; systematics, transparency, alternatives, complexity. The classification of budgeting methods is carried out according to the following classification features: selection of budget planning objects, initial base, budget development procedure, level of centralization, level of adaptation of budget planning to changes in the external environment, method of planned budget indicators calculating. It is determined that budgeting as well as any economic category has its advantages and disadvantages, the main of which are given in this article.
Modern business conditions necessitate entrepreneurs to take into account changes in both internal and external environment, actively master innovative management technologies, study market conditions, take into account the probability of certain events and at the same time develop models of enterprise behavior in the absence of sustainable development in labor, material, information and financial resources.
A significant number of business representatives appreciated the benefits of applying the budgeting process in practice, which is one of the management tools and has become widespread in economically developed countries. Budgeting is not a universal method of avoiding negative impact on the results of their activities, but provides an opportunity to navigate in a real fast-changing environment and make the necessary sound management decisions that will provide optimal conditions for business development in an unstable economy. The practical application of budgeting becomes an objective necessity, as it helps to optimize resource flows, ensures economical use of all types of resources, affects cash flow management, increases financial discipline, the level of investment attractiveness and competitiveness of enterprises.

The article considers the role and mission of the customer service in engineering activities during the design and implementation of investment and construction projects.
The essence of engineering, its legal definition, types of engineering at different stages of investment projects are revealed, it is determined that the main purpose of cost engineering is to stimulate for economical work, which is possible through the use of effective engineering solutions.
The review of theoretical approaches and methodical recommendations to the concept of "engineering activity", "cost engineering", ways of estimation and formation of effective service of the customer on engineering activity at stages of designing, erection of construction objects, commissioning is carried out. Cost engineering has been identified as an integral part of engineering. The legal support of engineering activities is considered.
It is proposed to classify engineering activities according to the functional approach in accordance with the stages of investment projects, namely: pre-project engineering - pre-project stage, project engineering - maintenance of project documentation, construction engineering - engineering activities during construction of facilities - commissioned and further operation, cost engineering - cost optimization at all stages of the investment project, not just at the design stage. The author's classification will allow to coordinate the types of engineering activities with the main stages of implementation of investment and construction projects and will facilitate the customer's services to choose areas for improvement of ongoing projects.
It has been proposed for the leading Ukrainian universities to conduct advanced training and introduce the second level of higher education in higher education in the specialty "Сost Engineering in Construction".
Investment crisis: causes and ways to overcome
Authors: Kishchenko T. 
Published: November 2021

The article considers the main features and peculiarities of the investment crisis, which is an element of the systemic crisis that has gripped the state economy and negatively affects all spheres of public life and activity. The investment crisis is an obstacle to operational, investment and financial activities of construction companies, causing demand for real estate. The global internal causes of low investment activity are analyzed, which are, first of all, the current state of the state economy, which increases investment risk and significantly complicates the formation of investment programs, creates conditions for illegal withdrawal of investment resources from the real economy to other areas. All this is a consequence of insufficiently deep development of regulatory and legal framework for the development of investment activities in the country: the existing legal norms do not work, there is no effective mechanism of punishment and property liability for improper use of investment resources, and the result - violation of the investment process. Among the identified and the ways of overcoming the investment crisis mentioned in the article are as follows: renewal of domestic sources of investment resources in the real economy, which were paralyzed in the last years of the country's life, the need to strengthen strong incentives and arguments for returning lost domestic capital from abroad. The creation of new laws on the efficient use of own sources to finance domestic investments in the modernization of production and introduction of new, modern technologies, as well as laws that will prevent the outflow of capital from the state during the acute investment crisis. The lack of a clear legal framework and non-compliance with current legislation is the main reason for the significant reduction in investment in Ukraine, both domestic and foreign.
Transformation of the Ukrainian cities within post-Chornobyl and Post-totalitarian ‘transitional’ period

Published: November 2021

The study of the transformation of Ukrainian cities in the post-Chornobyl and post-totalitarian transition period highlighted a number of general development trends and regional features of the global urban process. Despite the socio-economic upheavals, Russia's military aggression and population decline, Ukraine has entered the ‘human development high category’ list of countries. Studies have shown that the country urbanization level continues to grow, while balancing its spatial development potential. This is evidenced by the emergence of the ‘South-West Spatial Vector’, the ‘West Sector’ and the ‘Meridional Axis’ of the urbanization process development. This indicates, first, the ‘spatial structures memory’, the presence of which allows us to interpret post-socialist transformations as a ‘return to pre-socialist development trajectories’ of Ukraine in common Pan-European space; secondly, on the cyclical development and reversibility of ‘waves vibrational motion’ of the world urban process; thirdly, the ‘country urbanized space reaction’ to the Russian military aggression in the East of Ukraine, the annexation of the Autonomous Republic of Crimea and part of the Donbas territories.
The specifics of the post-socialist development of the Kyiv Agglomeration reflect the new status of Kyiv and the general trend of development of the European metropolitan network, as well as the ‘gravitational pattern’ of spatial development, which is manifested by territorial uneven economic development and ‘growth poles wave migration’ from center to periphery and vice versa. The post-Chornobyl growth of the tourist attractiveness of the Chornobyl Exclusion Zone, where 80% of visitors are foreigners, will contribute to the further transformation of Ukrainian cities. In particular, air communication − the development of Kyiv and the Kyiv Agglomeration; roads − development of bordering cities in the west and south of the country, as well as cities in the areas of Pan-European transport corridors influence; railway - the development of Kyiv, Chernihiv, Slavutych; the Dnipro - Visla waterway project implementation, the purpose of which is the connection of the Baltic and Black Seas - the development of city-river ports along the Dnipro and Pripyat Rivers.
Stabilization of the process of mechanized pulsed-arc welding
Authors: Maksimov Sergey , Gavrilyuk Anatoly , Krazhanovskyi Denys 
Published: November 2021

The main disadvantage of the mechanized arc welding process in shielding gases with short circuits is the spatter during melting of the electrode metal and its transfer to the weld pool, which affects the productivity of the process, reducing it. Its elimination is possible through the implementation of the controlled transfer of molten electrode metal into the weld pool. The implementation of such a transfer and the control of the processes that take place in the arc gap to a large extent determine the conditions for the qualitative formation of the deposited metal, the stability of the process, the magnitude of the loss of electrode metal and the manufacturability of the processes of arc welding in shielding gases. At the present stage of development of welding technologies, controlled transfer of electrode metal is possible due to the pulsed nature of arc burning. In this case, one of the main methods for increasing the efficiency of the process is to limit the maximum value of the short circuit current by increasing the inductive resistance of the welding circuit.
The research aimed to determine the effect of the rate of rising of the welding current during a short circuit on the stability of the welding arc. It was found that an increase in the current growth rate, starting from 1.23 kA/s to 50 kA/ s, leads to a decrease in the average duration of short circuits by at least 10 times. At the same time, the average frequency of short circuits increases by more than 2 times, from 36...38 s-1 to 80...86 s-1. The reason for this is the increase in the values of the electrodynamics’ Lorentz force, the action of which leads to the compression of the liquid metal bridge of the drop (pinch effect) due to an increase in the short circuit current. At the same time, there is a violation of the stability of the pulse process, and this is reflected in an increase in the average frequency of arc breaks by more than 30 times from 0.33 s-1 to 10 s-1. An increase in the energy parameters of the welding process led to a decrease in the average frequency of short circuits (2...3 times) and their average duration (2 times). The reason for this should be considered a change in the type of transfer of liquid metal – the welding process with short circuits has turned into a mixed process in which, along with short circuits, a droplet transfer of electrode metal is observed.

Published: November 2021

Objective: Hydatid cyst disease is a widespread zoonotic disease infecting humans as an intermediate host. Since the first description of this pathology, many modalities have been introduced into modern treatment protocols. Minimally invasive surgical treatment is well-described and widely used, but has many points where rationalization and modification can be applied. In this case series, we describe small differences in surgical technique and the corresponding treatment results.
Materials and Methods: Out of 44 patients, 16 were included in this study. Patients were retrospectively evaluated in two groups in accordance with the preferred cyst aspiration technique, i.e. via a standard laparoscopic aspirator or a large diameter venous catheter (the control and study groups, respectively). Demographic, clinical and surgical data like duration of surgery, hospital stay and complication rates were evaluated in both groups.
Results: Equal numbers of males and females participated, with a median age of 40 years. Most patients had a type III hydatid cyst (n=11, 68.75%). Surgery duration and hospital stay were significantly shorter in the study group, without a significant difference in terms of complication rates.
Conclusion: Laparoscopic procedures quickly became plausible for selected hydatid cysts located in liver. Success of such procedures shows to be depending on the success and duration of the laparoscopic intervention. The latter, according to our calculations, seems to be inversely proportional to the diameter of the aspirator tip and its piping.

Published: November 2021

Objective: This study aimed to determine the relationship between nurses’ perceptions of emotional labor, organizational loyalty, and their turnover intention.
Methods: This study was conducted in a private hospital in Ankara and two hundred and seven nurses participated. Correlation analysis was used to determine the relationships between variables. Multiple linear regression analysis was used to measure the effect of emotional labor and organizational loyalty on turnover intention. The data were obtained using the Emotional Labor Scale, the Organizational Loyalty Scale, the Turnover Intention Scale, and an information form developed by the researchers to inquire about the personal and professional characteristics of the nurses.
Results: Nurses’ perceptions of organizational loyalty had a negative effect (-0.664) on their turnover intention. Twenty percent of the change in nurses’ turnover intention is explained by organizational loyalty and the dimensions of emotional labor, namely, superficial acting, deep acting, and natural emotions.
Conclusion: It was found that the emotional labor and organizational loyalty perceptions of the nurses were at a moderate level, whereas their turnover intention was low. It was found that only organizational loyalty had a significant effect on nurses’ turnover intention.
Combinatorial Analysis of AT-Rich Interaction Domain 1A and CD47 in Gastric Cancer Patients Reveals Markers of Prognosis

Published: November 2021

Background: The AT-rich interaction domain 1A (ARID1A) is thought to be a tumor suppressive gene, and most of its mutations result in loss of expression of ARID1A protein. Combined with SIRPα on the surface of macrophages, CD47 on the surface of cancer cells can send an antiphagocytic “Don’t eat me” signal to the immune system that helps to avoid immune surveillance. However, the relationship between ARID1A and CD47 expression and their prognostic value in gastric cancer (GC) are still unknown.Methods: In this study, we evaluated ARID1A and CD47 expression in 154 GC patients’ tissues using tissue microarray. Expressions of ARID1A and CD47 in GC cell lines were determined by western blot and quantitative reverse transcriptase–polymerase chain reaction (qRT-PCR) techniques, and cell membranous CD47 expression was quantified by flow cytometry. In addition, chromatin immunoprecipitation (ChIP)–qPCR was used to determine the aspects of regulation of CD47 by ARID1A. The proportions of tumor-infiltrating immune cells were estimated on The Cancer Genome Atlas (TCGA) data set by using quanTIseq and EPIC algorithms. The infiltration of M1-polarized macrophages, M2-polarized macrophages, and regulatory T cells (Tregs) in GC tissues was determined by multispectral immunofluorescence.Results: A significant correlation was found between loss of ARID1A and high expression of CD47 at protein level in GC. By integrating 375 bulk RNA sequencing samples from TCGA data set, we found that mutated ARID1A correlated with high CD47 expression. In GC cell lines, knockdown of ARID1A significantly increased CD47 expression both at protein and mRNA levels as measured by western blot, qRT-PCR, and flow cytometry. Moreover, ChIP-qPCR revealed that CD47 was a direct downstream target gene of ARID1A in GC. Utilizing univariate and multivariate survival analyses, we found that patients with ARID1AlossCD47high expression had a worse prognosis. Estimation of infiltrating immune cells on TCGA data set showed that a higher infiltration proportion of M2 macrophages and Tregs was found in ARID1AmutatedCD47high expression subgroup. Furthermore, application of multispectral immunofluorescence revealed a higher infiltration proportion of M2 macrophages and Tregs in ARID1AlossCD47high GC tissues.Conclusion: Loss of ARID1A is strongly correlated with high CD47 expression in GC, and combination of ARID1A and CD47 is a promising prognosis factor in GC.
