Анотація. Досліджено теоретичні, методологічні та прикладні аспекти обліково-аналітичного забезпечення оцінювання стану та рівня економічної безпеки підприємства. Висунуто гіпотезу, що економічна безпека підприємства є комплексним і складним поняттям. У загальному варіанті її можна визначити як відсутність різного роду небезпек і загроз або наявність можливостей щодо їх попередження, захисту своїх інтересів і недопущення втрат нижче від граничної межі. У контексті зазначеного основною метою менеджменту підприємства є своєчасна оцінка стану і рівня економічної безпеки та ухвалення виважених управлінських рішень щодо його поліпшення. Визначено, що зазначене потребує наявності адекватної та релевантної інформації, яка формується в обліково-аналітичній системі підприємства. Систематизовано загальні важливі складові обліково-аналітичної інформації як основи обліково-аналітичної системи економічної безпеки підприємства. Виокремлено актуальні напрями і завдання діяльності аналітика з питань фінансово-економічної безпеки підприємства. Обґрунтовано, що діагностика є дієвим і важливими інструментом оцінювання стану та рівня економічної безпеки підприємства. Розглянуто напрями, види і форми діагностики щодо оцінювання стану та рівня економічної безпеки підприємства.

Анотація. Доведено, що впровадження принципів та використання інструментів корпоративної соціальної відповідальності дозволяють підвищити репутацію корпорацій та її активність на фінансовому світовому ринку. Метою статті є обґрунтування та визначення ролі корпоративної соціальної відповідальності компаній у забезпеченні та покращенні їх репутації на світовому фінансовому ринку. Обґрунтовано, що низький рівень практики корпоративного управління і недостатня частина соціальних відрахувань в компаніях негативно впливає на формування корпоративної соціально відповідальної поведінки корпорацій. Також, виявлено міжнародний та європейський досвід впровадження інструментів корпоративної соціальної відповідальності у діяльності корпорацій на світовому ринку та визначено фактори покращення репутації, пов’язані з цим. В статті проаналізовано показові індикатори для соціально відповідальних корпорацій за 2018-2019 рр. за рейтингами Fortunе Global 500, Net Promoter Score, Newsweek Green Ranking, які мають найвищу репутацію за даними Інституту репутації: Rolex, Lego, Disney, Adidas Group, Microsoft, Sony, Canon, Michelin, Netflix, Bosch. Аналіз показників надав змогу виявити пропорційну залежність репутації корпорації від заходів корпоративної соціальної відповідальності, яку вона впроваджує. На основі проведеного дослідження визначено, що корпоративна соціальна відповідальність є ефективним інструментом забезпечення підвищення показника конкурентоспроможності як для корпорацій, так і держави на фінансовому ринку.

Published: December 2020

Abstract. Ensuring economic security is a guarantee of independence and autonomy of the state, an integral condition for stability and effective functioning of society. Given the development of the world economy, ensuring the economic security of Ukraine, which is the basis of national security, is becoming an increasingly urgent problem. The formation of the system of economic security of Ukraine takes place in the conditions of economic globalization, which can not but affect the national interests and trends of socio-economic development of the country. It is to address this result that the issue of regulating the role and place of economic security in the general system of public administration mechanisms in Ukraine arises. In today’s realities there is a negative trend of increasing influence of external and internal threats on the activities of the state and its management. The modern concept of state development provides a single set of requirements for its institutions: openness of legal and economic systems; transparency of the mechanism of public administration, its economic, legal and information support; protection of economic interests of the state, social protection of life and health of the population, etc. Improving the management of economic processes in the state should begin with the development of a clear procedure and mechanisms for identifying and neutralizing threats in the system, which will contribute to the development of effective economic policy, state control over the socio-economic system, objective prioritization of economic reform, etc. Assessment of the current state of economic regulation has revealed that the main energy of the executive branch is spent not on overcoming the causes that provoke illegitimate phenomena, but on combating their consequences, so it requires the development of effective mechanisms for public administration of economic security.

Анотація. В умовах розвитку інноваційної економіки важливим є створення нових кластерних форм і моделей спільної діяльності, що максимально повно враховували б цілі та потенціал учасників та особливості територіальної локалізації взаємодії суб’єктів економічної діяльності однієї або суміжних галузей економіки. У зв’язку з цим актуальними напрямами дослідження є розроблення інструментарію ефективної взаємодії учасників інноваційних кластерів з метою підвищення їхньої конкурентоспроможності та забезпечення стабільного розвитку кластера в цілому. Мета статті — моделювання раціональної структури інноваційного кластера для підвищення конкурентоспроможності його учасників. Пряме використання численних моделей і методів аналізу й оптимізації реальних кластерних структур — достатньо важке через складність і велику розмірність такого роду завдань, але можливе, якщо для опису асоційованої діяльності учасників інноваційного кластера будувати імітаційну модель, що повинна містити в агрегованій формі всю наявну інформацію про модельований процес, і для її дослідження використовувати декомпозиційний підхід. За допомогою економіко-математичного моделювання розраховано імітаційну модель, орієнтовану на вибір оптимальної структури кластерного об’єднання, раціонального складу його учасників, а також цілей їхньої асоційованої діяльності у складі кластера. При цьому для визначення напрямків побудови такої моделі з усього спектра специфічних властивостей інноваційного кластера обрано ті, що визначають його економічний зміст як особливої модельованої конструкції. Запропонована імітаційна модель може бути використана для проведення кількісної оцінки доцільності створення територіально-виробничого об’єднання кластерного типу за умов більш повного врахування специфіки території (регіону) розташування кластера, особливостей галузевої належності його потенційних учасників, ступеня сприяння інституційному середовищу такій асоційованій взаємодії для конкретних учасників і конкретної територіально-локалізованої економічної системи.

AN ANALYSIS OF THE EUROPEAN INTEGRATION PROCESSES IN UKRAINE

Published: December 2020

Abstract. The purpose of the article is to analyze the efficiency of cooperation between Ukraine and the European Union, in general and expediency of Ukraine’s joining the Free Trade Area, in particular, as well as to prove the expediency of European integration processes, in general. The article deals with the history of the development of Ukraine’s integration into the European Economic Community. The main expectations, risks and results of measures aimed at integrating the Ukrainian economy into the European one are considered. Two main viewpoints on the results of the European integration are revealed. The first one is that the European integration is a blessing in all respects, it has no obvious and significant risks and should bring economic and social prosperity to Ukraine, promote Ukraine’s transition to the European social standards, due to economic growth caused by expanding target markets for Ukrainian products (giving access to the capacious European market), guarantee rapid growth of direct foreign investment in the Ukrainian economy, the improvement of the export-import balance, the creation of new jobs, the intensification of innovation processes and an increase in tax revenues to the budgets at all levels, the revamping of Ukrainian industry and the entire economy. The second viewpoint is quite opposite to the first one. It says that the European integration will cause deindustrialization, accompanied by a massive reduction of jobs; emigration of a significant and most capable part of the population; and as a consequence, acute shortage of labor resources, catastrophic increase in social tension and Ukraine’s transformation into Europe’s raw material appendage. Research carried out in the field of investment activity confirms the collapse of direct foreign investment in the Ukrainian economy during the period of the EU integration. Currently, foreign investors, at best, take a wait-and-see attitude, waiting to see the direction in which Ukraine’s political, economic and social development will go. The state of the trade-economic balance with the EU has deteriorated noticeably, as well as the state of the labor market and innovation activity. The research carried out clearly confirms the validity of the second viewpoint. Further studies of integration processes should be aimed at a significant modification of the goals and directions of Ukraine’s European integration, and should help Ukrainians to find a way out of the socio-economic crisis and rank high in the global division of labor.

Published: December 2020

The success of software development depends very much on the competencies possessed by human resources within the development team. These competencies include hard and soft skills. In this study, a team competency model will be proposed, which consists of the minimum competency level for the project manager, analyst, and programmer job roles. The types of competencies that are focused on in this paper consist of soft competencies and hard competencies. The method used to determine the competency model is to use the Focus Discussion Group (FGD) by adopting the Behavior Event Interview (BEI) technique. The result of FGD validates with expert judgments, questionnaires, and team member interviews. This research provides the results of profiling the competency of the software development team on project manager job analysts, analysts, and programmers. This study's competencies profile stated that the average minimum level of soft competency for project managers is 3, 3 for analysts, and 2 for programmers. In comparison, the average minimum level of hard competency for a project manager is 3, analyst 2, and programmer 2. Job Role for project managers requires high enough competence both in terms of technical (hard competency) and soft competency. A job as an Analyst requires a level of soft competence higher than hard competency. At the same time, the job role programmer requires soft and hard competency at a low level, 2. The results of this paper can be useful for the recruitment team to get the right individuals to ensure the success of the project.

Published: December 2020

Solid substrate fermentation of cooked decorticated red sorghum was carried out by using mould Rhizopus oligosporus or Amylomyces rouxii. This study aims to investigate the growth of mould biomass by determining glucosamine and investigating the effects of fermentation on the changes in proximate composition, pH and total titratable acidity, and in-vitro starch and protein digestibility. Red sorghum was decorticated using a carborundrum discs to remove the bran. Decorticated sorghum was soaked in water (12 h for R. oligosporus and 1 h for A. rouxii fermentation), heated up to 90oC for 30 min, steamed for 30 min, and sterilized at 121oC for 20 min). Fifty g of sterile sorghum was inoculated with R. oligosporus (6.103 spore/g substrate) or A. rouxii spores (2.103 spore/g substrate) then incubated at 30oC. Samples were taken at 0, 12, 18, 24, 30, and 36 h for R. oligosporus fermentation and 0, 24, 48, 72, 120, and 168 h for A. rouxii fermentation. The results indicated that glucosamine content of fermented sorghum by R. oligosporus and A. rouxii were 4.49 and 11.72 mg/g dry matter at the end of fermentation, respectively. R. oligosporus hydrolyzed up to 11.4% of initial starch and 63.4% by. A. rouxii. There were more protein and fat losses in R. oligosporus fermentation than A. rouxii. Both fermentations produced acid and lowered pH to about 3.0, but pH went up to 4.0 at the end of R. oligosporus fermentation. Mould fermentation improved in-vitro starch digestibility, in A. rouxii it went up from 31.3% to 37.9% and down again to 11.4% at the end of fermentation. In R. oligosporus fermentation, it went up to 35.4%. In-vitro protein digestibility went up from about 35.0% to 37.0% and to 51.8% by R. oligosporus and A. rouxii fermentation, respectively.

Real-Time Vibration Control of Rotor-Bearing System Based on Artificial Neural Networks and Active Support Stiffness
Authors: Tawfik Mauwafak Ali
Published: December 2020

A real-time dynamic response of the rotor-bearing system is controlled through an active support stiffness designed and constructed for this purpose. It consists mainly of a variable, flexible beam length. A stepper motor with a screw is implemented to manipulate the beam length to the required optimum position. Hence, it works as active spring stiffness, which minimizes the vibration response for the system. Stiff support is fixed at a specified position on the beam, and it is provided with a small ball bearing at the point of contact with the rotor at the other end. An artificial neural network has been used to control the dynamic system response. Response simulation with real-time LabVIEW is conducted to play a role as an interface to deal with the required sensors' records and the rotation of the stepper motor. The results show that the controlled system is efficient in obtaining the optimum support stiffness for different rotational speeds of the driven motor, which gives, in turn, the optimum system dynamic response.

Published: December 2020

In this paper, we have explored the potential of organic solar cells with gold layers, simulating different geometries and comparing them with the experimental data obtained from the devices produced at the “optoelectronic organic devices laboratory at Ben Gurion University of the Negev, Israel.” Thin-film heterojunction solar devices are analyzed using a basic chemical technology of GLASS/ITO/PEDOT,PSS/P3HT, PCBM, and another type of nanostructure where the gold layer is added. A standard device is realized on top of a transparent substrate such as glass or flexible polymer Polyethylene Terephthalate (PET). The first layer is the anode, which is made of conductive material and is also transparent. In our case, the very common material Indium-Tin-Oxide (ITO) is used. To facilitate the transition between the active layer and the anode, an intermediate layer is introduced. Hole Transport Layer (HTL) 's high hole mobility allows holes to move towards the anode instead of the cathode. On top of these layers the organic active layer is constituted by a blend of two organic materials configuring a multiple junction morphology (Bulk Heterojunction or BHJ). In our case, two commonly organic materials [6,6]-Phenyl C61 Butyric acid Methyl ester and Poly(3-Hexylthiophene-2,5-diyl) (PCBM:P3HT) are used. The cathode on top organic active layer is made of highly conductive opaque metal, mostly Aluminum (Al). The finite-element method has been used to compute the electromagnetic field distributions. The results show that the model with the gold layer increases the electrical performance of organic solar cells.

Published: December 2020

In Indonesia, dengue fever has been a public health problem for the past 46 years. According to the World Health Organization (WHO), in 2011, an estimated 2.5 billion people, or about 2/5 of the world population living in tropical and subtropical areas, were at great risk of being infected with dengue fever every year. This study aims to take advantage of the development of Android smartphone technology to design a system capable of screening the early stage of dengue fever with four possible classes, namely1stDegree, 2nd Degrees, 3rdDegrees, and non-dengue using the C4.5 Decision Tree based on patients medical records at Hajj General Hospital (Rumah Sakit Haji), Surabaya, East Java. The initial diagnostic decision of this application was determined by ten input parameters, i.e., unstable fever, conjunctival hemorrhage, rash, headache, age, pulse pressure, nausea/vomiting, body temperature, heartburn (abdominal pain), and decreased appetite. To determine diagnosis results in this application, trees formation using the highest gain ratio for each parameter was conducted. This early screening application for dengue fever patients recorded an accuracy score of 95% out of 20 data tested. Evaluation results for this application showed some good ratings by obtaining the average value of the survey in visual design and user interaction test at 8.3 rates; functionality test 8.932; performance and stability at 9.168; and overall satisfaction test at 8.733. This application also recorded a high accuracy level and good application performance.
Robust Approach of Optimal Control for DC Motor in Robotic Arm System using Matlab Environment
Authors: Al-khazarji Hasan Abbas Hussein , Abdulsada Mohammed Abdulla , Abduljabbar Riyadh Bassil
Published: December 2020

Modern automation robotics have replaced many human workers in industrial factories around the globe. The robotic arms are used for several manufacturing applications, and their responses required optimal control. In this paper, a robust approach of optimal position control for a DC motor in the robotic arm system is proposed. The general component of the automation system is first introduced. The mathematical model and the corresponding transfer functions of a DC motor in the robotic arm system are presented.  The investigations of using DC motor in the robotic arm system without controller lead to poor system performance. Therefore, the analysis and design of a Proportional plus Integration plus Divertive (PID) controller is illustrated. The tuning procedure of the PID controller gains is discussed to achieve the best responses of the DC motor. It is found that with the PID controller, the system performance is enhanced, especially in terms of steady-state error but does not provide the required optimal control.  The required approach of Ackerman's formula optimal controller based on state-space feedback is investigated. A GUI using the Matlab environment is created to obtain the DC motor's responses without using a controller and with controllers. It is found that the proposed approach of the optimal controller has more robustness and enhances the overall performance of the existing PID controller in the form of reducing settling times (from 2.23 second to 0.776 seconds), minimizing percent overshoot (from 27.7 % to 1.31 %) and zero value of steady-state error.

Authors: Cabezas González Marcos , Casillas Martín Sonia , Basantes Andrade Andrea Verenice
Published: December 2020

In 21st-century society, Information and Communication Technologies establish the ways of communication and socialization. The way we live, study, work, entertain ourselves, etc. have changed, and the patterns of social and economic development demand new skills from citizens. In Spain, the scientific and professional career called Social Education and their social educators, are responsible for promoting and facilitating the adaptation of people to society. Nowadays, these professionals must be aware that one of the fundamental competencies, along with others, is digital competence, and its development is a requirement to agree with contemporary society. This article presents the findings of a research that aims to be a pioneer in the field of study of Social Education in Spain and whose objective is to analyze the self-perceived digital competence of 452 working social educators and determine if demographic variables and professionals influence it. A quantitative, non-experimental, and descriptive method was used, with an ex-post-facto methodology, of a descriptive type in which no kind of treatment was applied to the object of study. The electronic survey technique was used to collect the information. For the analysis of the data, descriptive, inferential and regression tests were carried out. The main results obtained allow us to conclude that neither gender, nor age, nor the Autonomous Community influence the dimensions of management and attitude towards Information and Communication Technologies. On the contrary, professional variables do have an influence on the self-assessment of digital competence.

Published: December 2020

In this article, an updated approach to investigate the effects of demographic factors on economic growth is proposed. The initial hypothesis was that these factors significantly affected production proportions, determining development vectors. The predictable shifts in production dynamics are considered for the institutional framework. The article investigates the statistically significant relationships between the demographic variables and economic growth for the sample of the OECD countries (excluding Columbia) and Armenia, Belarus, Bulgaria, Croatia, Georgia, Kazakhstan, Romania, the Russian Federation, and Ukraine, from 1990 to 2017; unbalanced panel data was used. The investigation aimed to highlight the intrinsic interconnection between the changes in demographic variables (e.g., the working‑age population growth rate and the average life expectancy growth rate) and economic growth. Our investigation focused on the issue of whether demographic influence on economics was the same for advanced and developing countries in the sample. Over the period, a significant increase in life expectancy adversely affected the real GDP per capita growth rate. However, the empirical study pointed out that life expectancy was strongly linked to nominal GDP per capita. In advanced countries, the demographic indicator was considerably higher than in emerging markets. We found that the rise in the working‑age stratum of the nation’s population radically reduced the output dynamics as well, but that interconnection was not robust. The institutional framework should be taken into account in order to achieve a favorable performance of public governance in the long‑run. The main demographic variables should be properly forecasted and calibrated for potential endogenous economic triggers. Both public and private investments are important when considering the economic growth rates that are achieved. We propose a balanced approach to macroeconomic policy regarding both demographic and institutional determinants.
Progress in Achieving Sustainable Industrial Development – the Case of the Czech Republic and Poland
Authors: Ulbrych Marta
Published: December 2020

The aim of this paper is to clarify the concept of sustainable industrial development and present the results of a study on the progress in achieving goals in this field adopted by the United Nations (UN) in 2015. The research covered the Czech and Polish economies in the period 2000–2018. Under the United Nations 2030 Agenda for Sustainable Development, the need to promote inclusive and sustainable industrialisation was identified. In the context of sustainable industrial development, it is emphasised that it should encourage a competitive economy, create employment, and protect the environment by efficiently utilising non‑renewable resources. To assess this phenomenon in the analysed economies, indicators identified by the UN under SDG9 were used.
The Multiple Effects of Capital Controls
Authors: Zehri Chokri
Published: December 2020

Capital controls are seen as a means to promote financial stability or improve macroeconomic adjustment in economies with nominal rigidities and suboptimal monetary policy. Such controls may take various forms, including explicit or implicit taxation of cross‑border financial flows and dual or multiple exchange rate systems. Using a quarter dataset on capital controls actions in 27 emerging economies from 2010 to 2018, the study analyzes the effectiveness of capital controls (CCs) along different angles. Since the 2008 financial crisis, strengthening capital controls has allowed more monetary policy autonomy and exchange rate stability, verifying the Mundell‑Fleming trilemma model. Following CCs, the results show that accumulating international reserves may compensate for the loss of inflows and lead to more effective policies. Tighter CCs on inflows cause significant spillovers, specifically in the conditions of liquidity abundance. These spillovers originate from the problem of policy coordination of emerging economies and are mainly caused by capital controls being used as an instrument to manage capital flows. For governments that have to manage the risks associated with inflow surges or disruptive outflows, capital controls need to play a key role.

This paper attempted to investigate the trends or cultural attitudes of Arabic lecturers of East Java’s State Islamic Universities (PTAIN) in using Arabic. To this end, the present study used a quantitative approach The results show that the directive utterances used by Arabic language lecturers at East Java’s PTAIN tend to take the form of direct speech acts through certain language politeness features. Besides, the hierarchy of the directive politeness speech in Arabic and Indonesian shared a similar degree of illocution. However, there is no significant difference between the hierarchy of directive politeness speech in Arabic, Indonesian, and Javanese perceived by the Arabic language teachers based on the Chi-square statistics test with α = 0.05. Consequently, they tend to use non-Arabic socio-cultural norms in expressing various directive utterances in Arabic.

Authors: Wahyuni Dessy , Maulina Yeni
Published: December 2020

Riau is a wealthy region where physical development appears everywhere. However, many people are marginalized and neglected by this development. Due to this fact, most Riau Malay people tend to have negative prejudice and not accept the presence of foreign immigrants, including Indonesian Chinese. However, Olyrinson can blend in with the local community through his work, which often raises topics about humanity and his real-life. Using a three-dimensional framework of Fairclough (1989; 1992a; 1992b; 1995a; and 1995b), this study critically explores the various efforts made by Olyrinson in the short story "Jalan Sumur Mati" to defend his existence by changing prejudices. In this case, the author analyzes relevant texts and explores dialectical relationships between literary works and other social practice elements, which will be presented through textual analysis, discourse practice, and social practice.

Islamic paternal parenting has socially patterned the man dominant language behavior over woman since childhood. This study explores the dominance distributions of high female and low female status in their informal talk strategy, the actual language use,  among the students of The State Islamic Institute of Surakarta in three functional topical units of conversations. The analysis technique was introduced by Sinclair and Coulthard (1975), for which Leech (1983) modifies the speech acts. The data implies that the talk strategy among Muslim females is relatively similar to that of males. The higher female controls and initiates the interaction more while the lower is softer, more polite, more mutually supportive, and more cooperative to whomever she speaks to regardless of the status.Muslim Female; Act; Move; Talk Strategy
