Creating in the Crucibles of Nature's Fury
Authors: Dutta Sunasir
Published: November 2019

This paper examines foundings of human services organizations after natural disasters such as floods, earthquakes, wildfires, hurricanes, and tsunamis and explains why only some communities bounce back by founding appropriate collective-goods organizations. Using natural disasters in California counties from 1990 to 2010 as shocks that exogenously impose a need for collective goods over and above the level endogenous to the community, this paper shows that a geographic community’s local organizing capacity rests on the richness of its repertoire of voluntary organizing models as reflected in the diversity of its voluntary associations. Such diversity is even more critical when the type of natural disaster is more unexpected or complex (e.g., both a wildfire and an earthquake) in an area, and the organizational challenges posed are thus more novel for the community. Associational diversity has positive effects on both the numbers and aggregate size of foundings of local (non-branch, secular) human services organizations, and the effects are generalizable to other endogenous demand conditions such aspoverty. Results also show how different kinds of variety can have opposing effects onorganizing capacity as observed after a disaster, with associational diversity having a positive effect, political diversity having a negative effect, and racial diversity having no significant effect, net of other factors. The paper concludes with a call for treating community resilience as a matter of enhancing local organizing capacity over centralized planning efforts when the environment is rapidly changing.

Analisando a Variabilidade de Estimativas de Acessibilidade por Transporte Público a Partir de Dados de GPS
Authors: Braga Carlos Kauê Vieira , Loureiro Carlos Felipe Grangeiro , Pereira Rafael H. M.
Published: November 2019

Accessibility is a key concept in transport and land use integrated planning. General Transit Feed Specification (GTFS) has been used with success as a data source to estimate accessibility in recent years, but it relies on scheduled transit trips to estimate travel times between origin-destination pairs. On the other side, GPS data of a transit system can be used to calculate travel times between stops for each trip that happens in the system, but it can impose methodological/computational challenges and make use of median travel times to reconstruct the GTFS file. Using one month of GPS data from Fortaleza, Brazil, it is analyzed the variability of accessibility using empirical travel times and considering its dispersion. Results show that variability changes in space and between activities, possibly affecting the assessment and proposition of interventions on the transportation system.

Banyak orang salah mengerti tentang gembala, bahkan ada orang beranggapan bahwa gembala itu terlalu rendah dan lingkup kekuasaannya sangat kecil sehingga banyak pelayan Tuhan sekarang ini selalu menghindar dari identitas gembala. Sebenarnya kalau di telusuri kata gembala dalam Alkitab ternyata gembala sering disebutkan dalam Alkitab, mulai dari Kitab yang pertama, Kejadian, sampai Kitab yang terakhir, penyingkapan, atau Wahyu. Kej. 4:2; penyingkapan 12:5 Tokoh-tokoh seperti Abraham, Musa, dan Raja Daud, adalah gembala.
Amplitude Division Multiple Access Using Uniqueness of Prime Factorization
Authors: Shandilya Pradyoth H
Published: November 2019

A new method of amplitude division multiplexing (ADMA) is proposed, where a single channel can be used to transmit multiple digital signals simultaneously using the concept of prime number factorization. This method contrasts with the currently used methods such as frequency-division multiple access (FDMA), in whichthe total bandwidth available in a channel is divided into a series of non-overlapping frequency bands, each ofwhich is used to carry a separate signal. Comparison of the proposed method with a popular PAM technique-2B1Q method is made. Distinct advantages of the proposed method and a few applications arepresented.

Sertifikat tanah bukan hanya berfungsi sebagai tanda bukti hak saja, melainkan juga kunci akses terhadap modal. Namun ternyata persentase tanah yang diagunkan dibandingkan dengan sertifikat tanah yang diterbitkan oleh Kantor Pertanahan bervariasi antar daerah. Pengamatan yang dilakukan menemukan bahwa karena perbankan membutuhkan likuditas, maka masyarakat harus berpenghasilan relatif rutin untuk mengangsur pinjamannya. Akibatnya, dalam masyarakat yang dominan agraris, komoditas pertanian menjadi penentu untuk bisa dibiayai perbankan. Tanaman yang layak untuk diberi kredit oleh bank hanyalah tanaman perkebunan yang bisa berproduksi sepanjang tahun, seperti sawit, karet, kakao dan jeruk. Sementara untuk tanaman pangan, seperti jagung, kedelai dan padi, adalah jenis tanaman yang sulit dibiayai perbankan.
Votes at work in Britain: shareholder monopolisation and the ‘single channel’
Authors: McGaughey Ewan
Published: November 2019

Why do shareholders monopolise voting rights in UK companies, and are trade unions the only way to get meaningful workplace representation? In 1967 a Labour Party policy document first coined the phrase that a ‘single channel’ for representation should ‘in the normal’ case mean trade unions. Since then, it has been said the labour movement embraced an ‘adversarial’ rather than a ‘constitutional’ conception of corporations, neglecting legal rights to worker voice in enterprise governance. This article shows that matters were not so simple. It explains the substantial history of legal rights to vote in British workplaces, and competition from the rival constitutional conception: employee share schemes. The UK has the oldest corporations – namely universities – which have consistently embedded worker participation rights in law. Britain has among the world’s most sophisticated ‘second channel’ participation rights in pension board governance. Developing with collective bargaining, it had the world’s first private corporations with legal participation rights. Although major plans in the 1920s for codetermination in rail and coal fell through, it maintained a ‘third channel’ of worker representatives on boards during the 20th century in numerous sectors, including ports, gas, post, steel, and buses. At different points every major political party had general proposals for votes at work. The narrative of the ‘single channel’ of workplace representation, and an ‘adversarial’ conception of the company contains some truth, but there has never been one size of regulation for all forms of enterprise.

Authors: Samofalova N. E. , Dubinina O. A. , Samofalov A. P. , Ilichkina N. P.
Published: November 2019

In the regions of insufficient and unstable moisture, hydrothermal conditions are the main natural factors that determine the level of crop productivity. The purpose of our study was to identify the role of the main meteorological factors in the formation of winter durum wheat productivity at different periods of its growth and development. The study was carried out in the southern part of the Rostov region in the FSBSI “Agricultural Research Center “Donskoy” in 2003–2014. The objects of the study were winter durum wheat varieties and breeding lines of competitive variety testing, sown in black fallow, in four replications, with a plot area of 25 m². The current paper presents the analysis results of the average daily temperature, precipitation, hydrothermal index (HTI) by the periods of winter durum wheat growth and development through the years of study, average varietal productivity for each year. It has been established that the characteristic features of the studied years are a temperature rise, especially in the pre-sowing and sowing periods, during the wintering period and the resumption of spring vegetation, and irregular precipitation, their shift in the fall from November to October, in the winter from February to January, in the spring from April to March, and its decrease or absence during the active growing season. The conducted correlation analysis between main meteorological factors and productivity showed a decisive role of the temperature regime in winter durum wheat productivity formation. It turned out to be less significant in relation to precipitation. This indicates that winter durum wheat productivity does not depend on the total amount of precipitation, but on its distribution, moisture presence in soil, and temperature. According to the analysis of the main meteorological factors, their connection with productivity, there have been identified positive and negative points in the ontogenesis of winter durum wheat associated with climate change, which must be taken into account in breeding and growing technology. There have been determined the main objectives for winter durum wheat breeding, aimed at improving such adaptive properties as drought resistance, heat resistance, especially at the initial stages of growth and development, winter tolerance, disease and pest resistance occurred due to climate change (septorisis, pyrenophorosis, bacteriosis and fusarium of heads and kernels).

Authors: Ignatiev S. А. , Regidin А. А.
Published: November 2019

To stimulate livestock production increase, it is necessary to improve the production of high-quality feed with high protein percentage. The purpose can be achieved by an increase of sown area for perennial leguminous herbs and, in particular, alfalfa. The varietal alfalfa composition is constantly being replenished with new, more productive and adapted varieties for different growing zones. The biological potential of this crop allows now conducting its successful breeding. Annually the FSBSI “Agricultural Research Center “Donskoy” lays the alfalfa collection nurseries including breeding samples from different countries with certain useful traits. According to the study results alfalfa plant height ranged from 75.7 cm (“K-20367”) to 122.5 cm (“G-4”). On average, through the study, the samples formed a low yield of green mass. 19 samples had yields from 1.70 kg/m2 to 2.46 kg/m2 , which is significantly lower than the standard indicator (3.29 kg/m2 ). The samples “K-51698”, “G-1”, “K-50512”, “G-3”, “G-4” produced a significant excess of green mass productivity in comparison with the variety “Rostovskaya 90” (4.13–4.86 kg/m2 ). On average during the years of 2016–2018, foliage amount of the samples varied from 41% to 53%. The samples “K-50512”, “G-1”, “G-3”, “G-4” showed a significant excess of absolutely dry matter (ADM) productivity (from 1.42 kg/m2 to 1.65 kg/m2 ). Among the samples seed productivity varied in the range of 15.2–94.9 g/m2 . Only 3 samples (“K-50511”, “K-51201”, “G-2”) showed a significant excess in the studied traits compared to the standard variety “Rostovskaya 90” (63.3 g/m2 ), their seed productivity was 85.7 g/m2 , 86.8 g/m2 and 94.9 g/m2 , respectively. The protein percentage of absolutely dry matter according to the study ranged from 17.79% to 21.47%. The samples “K-43260” (20.95%), “K-50512” (21.34%), “K-31800” (21.47%) showed the largest indicators. In the current study there have been analyzed correlations between the studied traits.

Authors: Hawkshaw Rita , Markson Hannah
Published: November 2019

Introduction: This article describes the development of a model of well-being for children from military families in NATO countries. Methods: The development comprised seven phases: (1) a review of the participating NATO countries’ literature (current theory and research); (2) an outline of the key elements of a model of child well-being; (3) the identification of potential indicators of child well-being; (4) the identification of the components and dimensions of child well-being; (5) a review and refinement of the model; (6) the inclusion of the military factors that influence child well-being; and (7) the development of a definition for child well-being. Results: Thematic analysis was used to identify the well-being indicators, dimensions, and components. The process was informed by the subject matter expertise of the NATO Human Factors Medicine Research Task Group-258 (NATO HFM RTG-258), the civilian literature, and military factors associated with child well-being. Discussion: Central to the developed child well-being model are five dimensions of child well-being: health, education, legal, material, and social (HELMS). This model is closely aligned with well-established models and measures of well-being – Bronfenbrenner’s bioecological model of human development, Minkkinen’s structural model of child well-being, and the Organisation for Economic Co-operation and Development’s (OECD) measures of child-well-being. The proposed model takes into consideration relevant military factors that influence the well-being of children in military families.

Published: November 2019

Purpose: We describe the development, implementation, and outcomes of role-emerging (RE) clinical placements at Positive Living Niagara (PLN), a community-based HIV organization (CBHIVO), for two second-year, entry-level Master of Science (Physiotherapy) (MSc[PT]) students from McMaster University. Client Description: A national, not-for-profit organization , Realize, conducted outreach to identify CBHIVOs interested in developing physiotherapy (PT) student placements. Intervention: PLN responded to the outreach and worked with McMaster’s MSc(PT) programme and Realize to establish two part-time RE PT student placements. The placement description and expectations were developed collaboratively by PLN, Realize, and the MSc(PT) programme. All PT students participating in their third 6-week clinical placement were eligible to apply. A registered occupational therapist and physiotherapist and PLN’s programme services manager participated in a shared model to supervise the students’ clinical and administrative activities. Measures and Outcome: These first RE PT placements in a Canadian CBHIVO were completed between November and December 2016. The evaluation of the student and placement included a learning contract and the Canadian Physiotherapy Assessment of Clinical Performance. Over 6 weeks, the students collaborated with people living with HIV (PLWHIV) who were members of PLN to identify a role for physiotherapists at PLN and led two health promotion workshops for PLN’s members and staff. Implications: The RE PT placement identified future opportunities for physiotherapists at PLN. The experience also influenced one student’s decision to apply after graduation for a newly created PT position that included working with PLWHIV.
Microstructural and tribological characterization of molybdenum–molybdenum carbide structures produced by spark plasma sintering
Authors: Cekli Can , Goller Gultekin
Published: November 2019

Pure molybdenum is one of the most important refractory metals owing to its high melting point, low thermal expansion coefficient and good thermal conductivity. Molybdenum carbide exhibits superior wear resistance to molybdenum owing to its low friction coefficient and high hardness; therefore, in this study, to endure abrasive conditions, the surface of molybdenum was modified as molybdenum carbide. In accordance with this purpose, pure molybdenum powder was sintered under constant pressure (40 MPa), various temperatures (1 650 °C, 1 700 °C and 1 725 °C) and holding periods (180 s, 360  s and 540 s) using the spark plasma sintering technique. The effects of sintering temperature and holding period on relative density, microhardness, microstructure and wear properties of the specimens were investigated. Moreover, carbide formation on the surface due to carbon diffusion was also investigated. Relative density values decreased with increasing sintering temperature and period, obtaining the highest value of 97.55 % at 1 650 °C and 180 s. A microhardness value of 15.20 GPa was reached on the surface while the maximum value measured at the cross-section was 2.17 GPa, showing the formation of molybdenum carbide structure on the surface of all specimens. Furthermore, microstructural analysis supported the microhardness results and showed a minimum 288-μm thick molybdenum carbide layer on the surface. In addition, a typical eutectic microstructure was observed between molybdenum and molybdenum carbide layers; however, the decrease in temperature decreased the thickness of the eutectic layer and it gradually disappeared from the centre to edge of disc-shaped specimens. Wear resistance of surfaces was improved by decreasing holding period where a non-porous carbide layer and highest microhardness values were achieved. The cross-sectional analysis corresponding to molybdenum base metal proved that the formation of molybdenum carbide layer because of carbon diffusion improved the wear properties of the sample with the low friction coefficient and low wear depth.

ABOUT OF THE DYNAMICS OF FORCED OSCILLATIONS IN NONLINEAR SYSTEMS
Authors: Qurbanov A. N. , Sardarova I. Z.
Published: November 2019

The article discusses the issues of determining the effectiveness indicators of an electromagnetic vibration exciter in a dynamic mode of operation. It is established that this system is whole system of electrical and mechanical circuits. In this case, the mechanical part operates in the mode of forced vibrations. The oscillation parameters of the system, such as amplitude, frequency, and phase, largely depend on the parameters of the system load. For the analysis of this system, differential equations describing an electromagnetic vibration exciter have been compiled. For this purpose, the dependence L(x) of the inductance on the displacement is used. The dynamic modes of one of the ways of asynchronous excitation of an electromagnetic vibration exciter are investigated. The accuracy analysis and the evaluation of the results were performed by the Fisher criterion for the regression model. To analysis of transients in the electromagnetic vibration exciter, were used the software packages WinFact and MatLab to simulate and optimize dynamic systems. It is established that the system, depending on the initial conditions in the simulation, goes into one of two very different modes. In this case, the initial zero conditions switch the system into a “cyclic” mode, and in other, non-zero conditions, the system goes into an approximate cyclic mode, characterized by a higher speed of movement of the anchor. The parameters of the steady state cyclic movement are determined by the method of harmonic balance.

The obtained results allow us to describe autoparametric oscillations of the electric equivalent circuit. It has been established that the compilation of harmonic balance equations corresponding to a linear system helps simplify the solution of the task of determining the dynamics of forced oscillations. The expressions for determining the tractive force and the current flowing through the circuit are obtained, the wavelet spectra of vibration are constructed using the MatLab software package. As a result, for the mechanical part of a nonlinear system, in fact, it is necessary to solve only harmonic balance equation. The results show that this theoretical model allows a more qualitative and accurate assessment of the observed phenomenon. Based on this, the asymptotic conditions for solving the harmonic balance equations of a nonlinear system are determined. The expressions for the electromagnetic force acting on the anchor are obtained, the conditions for the harmonic balance of the mechanical part of the system are determined. The expressions obtained allow us to construct the amplitude-frequency characteristics of the electromagnetic vibration exciter. In conclusion, not only qualitative, but also quantitative estimates of the observed phenomena were obtained. It has been established that mechanical oscillations of a nonlinear system are insensitive to changes in the supply network and practically have a large amplitude with a constant frequency.
THE ELECTRIC DRIVE PUMPING UNITS STEADY OPERATING MODES OPTIMIZATION BY THE MODES RELIABILITY CRITERIAS
Authors: Yaremak I. I.
Published: November 2019

According to the research results, the target functions of the task of optimizing the functioning of the units according to the criteria of the regime reliability, depending on the flow of the working fluid were synthesized, which made it possible to research the influence of the regime on the reliability of operation of electric and hydraulic subsystems of the pump unit. The extreme weight of local target functions of regime reliability of electric motor and the centrifugal pump in various (especially low-flow rate) operating modes are determined. It is proposed to optimize the operating modes of  pumping units of oil pumping station with the simultaneous use of the reliability criteria of electric drive and centrifugal pump. . It was established that the maximum values of reliability of electric drive and centrifugal pump are achieved at different values of the load, which requires the involvement of multi-criteria optimization methods. The problem of optimization of the established modes of the pump unit in the multicriteria setting, taking into account the technological limitations of its subsystems was formalized. The analysis of modern methods of solving the problem of multicriteria optimization of the steady modes of operation of pump units is carried out. The method of solving the multicriterion optimization problem is substantiated, which fully takes into account the influence of operation mode on the reliability of electric and hydraulic subsystems of pumping unit. It is revealed that the most appropriate method for solving this problem is the method of approaching an ideal (utopian) point in the criteria space. With this method, the desired ratio of criteria at the optimum point is the best. The value of the "agreed optimum" of liquid flow has been determined in order to choose the optimum for the reliability of operation mode of the pumping unit of oil pumping station.
IMPROVING THE CAPILLARY METHOD OF NON-DESTRUCTIVE TESTING
Authors: Lopatin V. V.
Published: November 2019

The history of capillary control began in the 40s of the last century for the needs of the aerospace industry. Currently, the cost of quality control in the aerospace industry is up to 12 - 18% of the cost of products. Similar amounts of expenses in the nuclear and defense industries are not lagging behind other industries. For example, for the control of welded joints of oil and gas pipelines of large diameter and considerable length, the labor costs for inspection reach 10% of the total labor costs. Capillary quality control method is based on the ability of indicator liquids (penetrants) to penetrate into the cavities of surface defects (discontinuities). Over the 70 years of its existence, the capillary method of control has not undergone fundamental changes, and its principles have remained unchanged. In international practice, the abbreviated designation of types of non-destructive testing (AWS) is adopted, and the control with the use of penetrating liquid denoted RT. This method is applicable to the detection of all types of surfacedead-end and through defects, such as cracks, delamination, leaks, in products made from any non-porous materials, including glass, ceramics, plastics and other non-metallic materials. The analysis of the capillary method of nondestructive testing of the surface of a solid body is carried out, the possibilities and ways of its improvement are indicated. The method of the capillary method of non-destructive testing of a solid surface, the physics of the method and its implementation are considered in detail. It is shown that the wetting ability and spreading are important characteristics of capillary control fluids; therefore, they must be evaluated and analyzed when developing new ones, choosing or comparing known capillary flaw detection materials. The possibility of using the Rebinder effect to improve the capillary method of non-destructive testing of a solid surface has been proved. A refined method of capillary defectoscopy is proposed by taking into account the wetting ability, density, viscosity and evaporation of a liquid, which makes it possible to make an optimal choice of liquid to ensure high efficiency of surface (capillary)control. An improved method for assessing the wetting ability of liquids is proposed, which makes it possible to evaluate the wetting ability of liquids by the size of the spreading spot of their droplets, taking into account the influence of density, viscosity and evaporation of liquids intended for capillary flaw detection (penetrants).
THE MAIN CHARACTERISTICS AND FEATURES OF THE LOW-FREQUENCY WAVE PROCESS IN THE STRETCHED PIPELINES
Authors: Bondarenko O. G.
Published: November 2019

The problem of determining the technical condition of various pipeline systems, ensuring their reliable аnd safe operation has recently become the subject of geopolitics. In this situation, constant monitoring of their technical condition is essential for the maintenance of pipelines. However, it is technically difficult to monitor the technical state of pipelines by conventional methods of non-destructive testing (NDT).

An analysis of the essence of the wave process in diagnosing the technical condition of long pipelines by low-frequency ultrasound directed waves is performed. The types of modes of directed waves and peculiarities of the wave process in the solid medium of the pipeline are given. Dispersed diagrams of  ound velocities for different modes of directed waves are considered, on the basis of which their main features are formulated in the diagnosis of the technical state of extended pipelines. The analysis of the wave process in the long pipeline from the position of the acoustic location of its solid medium by low-frequency directional waves is made, the model of the active localization system is developed in diagnosing the technical state of the pipeline, the principles of excitation and displacement of the particles of the medium of the pipe wall are considered in the distribution of longitudinal, twisted and bending mods of low-frequency ultrasonic directed waves.

When choosing the frequency and mode of the directed wave to diagnose the technical state of long pipes, it is necessary to take into account that the directed wave is the result of the interaction of the vibrations generated by the transducers with the pipe surface. A significant factor determining the efficiency of energy transfer from the antenna to the body of the drainage pipeline is the harmonization of the internal resistance of the converter and the load due to the static force of pressing the piezoelectric transducers to the pipe surface. When creating systems of low-frequency ultrasonic diagnostics of long-distance pipelines directed waves it is necessary to take into account the main features of the wave process, which has a complicated mechanism of propagation over the thickness of the pipe wall.

The work is devoted to the investigation of the effectiveness of the coordinate search methods for solving the problem of finding the position of the solar panels, in which the greatest power of the produced current is achieved. The existing solutions in the market of sun surveillance systems (solar trackers) are analyzed. The advantages and disadvantages of such systems are presented in comparison with fixed panels. It is proposed to improve the hardware and software for research of the solar panels efficiency, developed by the authors and highlighted in the previous works, by integrating the program realization of the algorithm of coordinate search of the maximum power of solar panels into the existing. For this purpose, the efficiency of three algorithms for coordinate search of the maximum, namely, the method of coordinate ascending, the Huck-Jeeves method and the Rosenbrock method, was studied in three parameters. Experiments were carried out on data obtained both experimentally using the lab stand for solar panel efficiency research, and by generation using mathematical model of the solar panel efficiency dependance on the angle of radiation, described in previous works. TThe results of experiments are analyzed, which showed a fundamental difference between the work of coordinatewise search algorithms on a mathematical model and experimental data. The main indicators of the efficiency of algorithms are substantiated on the basis of the meteorological conditions in which the measurement was carried out for the formation of experimental data. Conclusions are drawn regarding the efficiency of using these coordinate-based search methods for solving the problem of finding the optimal position of solar panels. Further prospects for research on this topic and the possibility of using coordinate-wise search methods in software of solar panels with a biaxial orientation on the position of the Sun are given.

In connection with the necessity to unify the procedures and requirements applicable to goods and services, first of all, with regard to conformity assessment, in order to eliminate technical barriers to trade, a list of methods for testing mineral waters has been analyzed, according to which their assessment of conformity and determination of individual safety and quality indicators. The paper analyzes the metrological characteristics of the methods approved in the form of international, national standards, standards adopted before 1992, test methods for assessing their suitability for implementation not only in the testing, but also in the production laboratories. According to the results of the analysis of 42 indicators of the measurement methodology, which are specified in DSTU 878-93 (regulatory document on packaged mineral water) and GSTU 42.10-02-96 (normative document on medical waters used in sanatorium practice), 13 indicators , which are mandatory, as they are specified in the relevant normative documents, are not valid. According to the results of the analysis of the metrological characteristics of the methods of testing the indicators of safety and quality of mineral waters, a list of methods of tests of mineral waters for the period 2019-2021 has been developed, which includes national standards certified in Ukraine methodology and GOST for drinking water, in particular, on sulfates, ammonium and iron . However, the effect of these GOST on the testing of drinking water after 2021 will be abolished, and they should also be replaced either internationally or to develop national standards. In selecting the methods of testing mineral waters, two aspects were taken into account: the conformity of metrological characteristics of the methods during the assessment of the conformity of mineral waters, taking into account the features of the composition of the mineral water itself (applicability of the method for both low and high mineral waters), and the economic feasibility of testing for the appropriate method (due to the impossibility of many testing and production laboratories to use high-value equipment). In order to provide modern standards (international and national) of packaged mineral water producers and test laboratories conducting an assessment of the conformity of mineral waters, a list of methods for testing mineral waters, which is to be developed in Ukraine for the replacement of interstate GOST or methods, the metrological characteristics of which do not correspond to the current one, is proposed. in Ukraine the rules of legal metrology, and to give them the status of national standards (for the definition of Pseudomonas spit, sulfates, ammonium, bro copper and iodide). This will enable Ukrainian producers of packaged mineral water to optimize production costs for the production of Ukrainian products and successfully expand its share in the foreign market.
A Comparison of the Structural Elements of the Integrated Reporting and the Management Report

Published: November 2019

A new type of reporting has been introduced both in the international and Ukrainian practice: the integrated reporting and the management report. The integrated reporting in Ukraine is not subject to regulation by central government, whereas the structure and format of the management report is legally fixed (the Law of Ukraine “Accounting and Financial Reporting in Ukraine). However, as of 01.12.2018, a unified format for the management report was not approved by the Ministry of Finance of Ukraine. According to the abovementioned Law of Ukraine, micro-enterprises and small enterprises are exempt from the management report, whereas medium enterprises are not obliged to show non-financial data in the management report. The integrated reporting can be submitted separately from the financial reporting, but, following the above Law of Ukraine, the management report is to be submitted together with the financial statement and the consolidated financial reporting in the legally fixed procedure and time limits.         
The purpose of the study is to compare the structural elements of the integrated reporting according to the International Integrated Reporting Framework, the management report according to the Draft Methodical Recommendations on Compilation of Management Report by the Ministry of Finance of Ukraine, and the management report according to the Draft Methodical Recommendations on Preparation of Report from Kreston GCG, in order to identify their differences and the feasibility of their simultaneous application in the national reporting practice. Based on the analysis, the main differences between the Integrated Reporting and the Management Report are highlighted. A comparative analysis of the structural elements of the integrated reporting and the management report is conducted, to find out the correlation of their structural elements. It is demonstrated that the differences between the integrated reporting and the management report are negligible; it is, therefore, recommended to combine these two types of reporting in one optimal format.

Published: November 2019

The article deals with the key technological trends underlying cyberphysical systems. The questions of constructing the smart industry as a cyber-physics system are described in their context the, barriers and risks are described in the transition to smart technologies in the economy and ways of overcoming them.
The combination of the Internet and material things forms new opportunities for managing the physical world, including devices, factories and infrastructure that determine the modern economic landscape. The next 10 years of Internet of Things can radically change the manufacturing industry, energy, agriculture, transport and other sectors of the real economy, accounting for almost two thirds of world GDP. Due to the processes of digitization, such transformations will have far-reaching consequences in terms of redistribution of resources and markets of the present world.
Technically, the smart industry integrates advances in the field of physical devices with advances in the field of information and communication technologies, which results in the formation of cyber-physics systems. For Ukraine, the special significance of smart industry is also determined by the fact that its traditional industry is currently in crisis, and the new “smart” industry has not received enough attention from the state. In the developed plan, the government’s priority actions in the Ukrainian economy for the period up to 2020 are smart industry (Industry 4.0, Internet industry, advanced digital production, etc.), unlike US, China, EU countries and other industrial leaders in general not considered, especially as a national strategic investment.
The possibilities of using cyber-physics systems in various branches of economy and socially important systems are described. Examples of smart manufacturing are presented in modern conditions of Ukraine.

The analysis of investment cooperation between Azerbaijani Republic and Ukraine shows a positive trend from 2014 and on. As of December 31, 2017, the Ukrainian economy attracted investment of 213 million USD from Azerbaijan. The main sectors of Azerbaijani investment in Ukrainian are wholesale and retail trade, repair of motor vehicles, construction and industry. Direct investment of Ukraine to Azerbaijan in 2017 amounted to 25 million USD.
The clear position of the Azerbaijani government in terms of facilitating business conditions can help attract Ukrainian investment and Ukrainian business to cooperate with Azerbaijani companies. Comfortable taxation, the termination of two years of inspections of business entities, the possibility of obtaining financing: all this increases the attractiveness of investment in small and medium businesses in Azerbaijan and makes the country attractive for foreign business.
The study shows that the current state of military-technical cooperation is not in the best condition, but it has significant potential for development. In this regard, the promising area of military-technical cooperation between Azerbaijani Republic and Ukraine is the transfer of Ukrainian experiences in the production of light-weight wheeled vehicles such as APCs, radar detection of air targets, and anti-personnel combat weapons. Most importantly, all of this technique will be more competitive in terms of price compared with Western counterparts and with the already existing experience of counteracting the latest Russian technology and technologies (which are actively used in the Donbass).
A promising area of cooperation may be the transfer of experiences in the modernization of anti-aircraft missile systems of Soviet production. This problem is now very actively engaged in our country at the state level and there are already real results. For example, Ukrainian companies were able to master the repair and modernization of missiles for such anti-aircraft missile systems as the S-300 (including modifications B1), Osa-AKM, and Cub-M1. There are good variants of modernization of missiles for the complex С-125, which is being armed with air defense of Azerbaijan.
