At the present stage of rapid formation of the digital space, the problems of e-commerce development are becoming relevant. The article aims at generalizing and systematizing the existing scientific approaches to the interpretation of the "e-commerce" concept, and substantiating the author’s approach to defining the essence and content of this term. To achieve this goal, methods of analysis and synthesis, comparison, structural and logical generalization, and classification are used. It has been found out that most researchers identify e-commerce with such concepts as e-business, Internet business, IT business, e-marketing, e-trading, digital marketing, Internet-marketing, Internet-trading, Internet-commerce, e-retail, virtual trading, distance trading, electronic trading. Scientific approaches to formulating the term "e-commerce" can be systematized according to classification groups: part of e-business; type of economic activity; economic activity; commercial activity; type of electronic commercial activity; type of entrepreneurship; specific type of trade; marketing strategy; type of business process; electronic interaction of economic entities; type of trade through information and communication technologies; electronic commercial agreement; type of public relations for the sale of goods; a set of rules for the implementation of electronic relations for the purchase and sale of goods. Summing up the results of scientific research on the conceptual framework, the author interprets the term "e-commerce" as a component of e-business, the essence of which is to strengthen partnerships in buying and selling products using digital technologies and information systems; as an effective form of organizing logistics activities of enterprises by using information and communication technologies and systems; as a tool for promoting products in the market using digital technologies.

The social and labor sphere in the conditions of digital transformation requires special care of the state and theoretical comprehension of the possibilities of the state employment regulation. The article aims at carrying out systemic analysis of opportunities, features and directions of the state influence on employment in the context of economy digitalization. Technological changes form new challenges in the field of social and labor relations, relations concerning the human resources formation and involvement, and the involvement of people in economic activities. These are changes that create uncertainty and risks both in the system of employment and self-realization of human labor potential, and in the system of income. Digital technologies have created a completely specific work process, bringing changes into all its elements, namely: the subject and means of labor, technology, organization and result of labor. The impact of digital technologies on labor market changes take place in several important directions, namely: the intensification of migration processes; interprofessional and intra-firm mobility; development of modern employees’ adaptive skills; ability to learn throughout life; growth of the competitive advantages of educated, professional, and creative staff; development of flexible forms of employment. Contradictory processes in the field of labor and socio-labor relations make special requirements to socio-economic policies in employment promote. Modern employment policy has close complementary links with human development policy. Its important direction is the one of creating an effective retraining system, helping to acquire new professional competencies, and it involves close cooperation with the educational sphere. Mechanisms for de-shadowing hidden unemployment and eradicating informal employment, especially its precarious forms, are of great relevance to the Ukrainian economy. An important aspect of expanding employment opportunities is promoting the development of remote employment together with its consistent institutionalism.

The definition of state policy on business regulation is understood here in accordance with the current Commercial Code of Ukraine, namely: it is a system of economic, social, organizational, legal and political support of a favorable business climate so as to form and develop small business. This understanding allows us to distinguish three blocks within state policy. The first block includes fiscal components of economic relations, primarily related to financing (this block includes monetary policy, investment policy, antitrust policy, depreciation policy, innovation policy); the second block includes organizational measures, in particular, support for small businesses, domestic banks and funds financing small businesses; the third block includes legal measures, namely: a simplified system of registration and licensing, improved tax legislation as for the implementation of international accounting standards, simplification of the accounting system for small businesses, etc. The classification of the system of state policy tools in the field of supporting and stimulating small business development is considered. Unlike others, it provides systematizing state influence tools in two main vector directions: state regulation tools and state policy tools of support and stimulation of small and medium business entities, which makes it possible to clarify the composition of each group. The composition of the state regulation mechanism of small business development has been clarified as one including functions, methods, means and tools, thus allowing us to single out the tools of state regulatory and coordination influence. The concept of state support for small business has been specified as a component of public policy, which is interpreted in the work as a set of methods and forms of promoting small business, taking into account the interests of the state and businesses, allowing us to formulate its purpose, directions and tools. The latter are divided into three groups by their features: state forecasting and planning of small business development by type of economic activity; tax and financial and investment support; information, advisory and institutional support for the development of small business entities

Published: February 2021

The purpose of the article is to study the main trends occurring in the investment climate of Ukraine, to analyze the main factors that have both positive and negative impact on the competitiveness and investment attractiveness of the domestic economy. As a result of the analysis, Ukraine’s position in the international ratings on investment attractiveness was assessed; the main directions of capital investment were identified, and investor countries were pointed out. Priority state projects are indicated, which are to increase the level of high-quality investment resources. At the same time, significant problems were identified that need to be addressed immediately in order to prevent a slow-down in creating an attractive investment climate for foreign and domestic capital. Systematization of a number of factors allowed to emphasize the need not only to attract to the economy financial resources from other countries, but also to intensify state policy that would promote the investment of Ukrainian funds through a system of incentives, and create the rule of law. Investment plays a central part in the development of a country’s economy; it is investment that makes it possible to implement the latest technologies or innovation; or to significantly expand production capacity of a business entity; or to solve a number of social problems. At the same time, the intensification of investment activity is impossible without promoting the accumulation of domestic financial resources, through a system that would stimulate Ukrainian people to save, and through institutional investors, to transfer capital to the real sector of the economy. Prospects for further research in this area are the following: to determine the degree of the state involvement in the development of a competitive economy; to find the ways to eliminate the imbalances and exogenous and endogenous factors that have a chilling effect on the investment process in Ukraine.

Authors:   Sumy State Pedagogical University named after A. S. Makarenko, Omelyanenko V. A.
Published: February 2021

The need to consider the institutional component of solving the problems of sustainable development forms a new analysis plane due to a significant expansion of the range of influence factors. At the same time, it becomes important to develop the practical aspects of substantiating the most important areas of institutional design. The study in question aims at analyzing the institutional aspects of innovation policy development in the context of sustainable development. To achieve the task, it is important that innovations cover not only technological changes, but also changes in organizational, labor and social practices as such, thus potentially influencing transition to sustainable development. The author sums up the innovative aspects of sustainable development goals. To identify the components of the "sustainable development – security" national system the author has adapted the OECD (OECD Well-being Framework) experts’ approach to the classification of sustainable development components through systematizing 17 sustainable development goals by capital type, institutional capital included. The calculations results show that institutional capital is the most problematic component of the "sustainable development - security" national system. The institutional-network approach to innovation policy involves assessing the entirety of institutions and their interaction patterns within active networks (institutional clusters), ensuring the transformation of resources into real results by effective methods in accordance with the national context and the society demands. Some aspects of this approach have been analyzed in a branch case study of the tool engineering development. The author suggests an institutional-innovative project outline in the sphere of tool engineering development. During the project implementation it is possible to realize the potential of the innovation network; to identify promising innovation areas within the network mentioned; to improve the mechanism of attracting private capital on the basis of the public-private partnership. It also becomes possible to develop new ways of intensifying innovation processes, thus causing an increase in the research and development efficiency, products competitiveness, and state support effectiveness.

The purpose of the article is to improve the scientific understanding of the essence of the categorical apparatus of inclusiveness and define the inclusive development of Ukraine as a system in its spatial dimension, sectoral and sectoral sections, political, economic, social and spiritual manifestations. It is determined that the systemic challenge caused by the global economic crisis, exacerbated by the epidemic of coronavirus infection, has focused on the problem of overcoming poverty and socio-economic inequality at both global and national levels, which in turn raises the issue of society's transition to principles. inclusiveness. It is substantiated that the issue of transformation of the model of development of society has become important against the background of the contradictory development of globalization, associated with the widening gap between the countries of the center of the world system and countries on its periphery. The scientific novelty of the study lies in the definition of stages, directions of creating the preconditions for inclusiveness, and in substantiating the systemic idea of inclusive development of Ukraine. To reveal the essence and structure of inclusive development of Ukraine, an analysis of the scientific discourse related to the categorical apparatus of research was carried out. An analysis of inclusive development was conducted based on the identification of paired dichotomies that reveal the essence and direction of this process. The rating of Ukraine according to the index of inclusive development among the developing country is presented. A systematic idea of inclusive development of Ukraine is formed, the components of which are inclusion as a social phenomenon, inclusive development as a process, its elements (objects) and result. Problems that have their manifestation at the national level, in the spatial dimension, sectoral and sectoral sections, in the political, economic, social, spiritual spheres of public life, and are certain obstacles to the formation of an inclusive society, prospects for social development based on inclusiveness. Prospects for further scientific research are in the plane of substantiation of the domestic model of inclusive development, which would take into account the specifics and current state of Ukrainian society.

The research is aimed at further developing the theoretical provisions, elaborating the methodological approaches together with scientific-practical recommendations as to the formation of models of the risk control on the part of client, taking into account the likelihood of implementation of network schemes in order to protect against money laundering and financing terrorism. The article closer defines the essence of the concepts of «model of the risk control on the part of client» (taking into account the main components of the model of the risk control on the part of client) and «network scheme». In addition, a classification of existing network schemes of legalization (laundering) of proceeds of crime is provided, on the basis of which a methodical approach to the formation of risk-control models is proposed, taking into account the likelihood of implementation of network schemes to ensure money laundering and financing terrorism. The proposed methodical approach includes four main stages: definition of the basis and components of the model; formation of an array of data for the assessment of risk control models of the bank’s clients; formalization of relationships and formation of a model for assessing risk control of client; assessment of the effectiveness of risk control models of the bank’s clients. A combined (combination of a single- and two-tier model) model of risk control of the bank’s clients given the likelihood of implementation of network schemes to protect against money laundering and financing terrorism based on a fuzzy cognitive card containing 28 components (conceptions) is specified. The effectiveness of the model of risk control of the bank’s clients regarding the implementation of network schemes by applying a script approach taking into account the variables of management factors, which include fines, written notifications and measures to minimize risks as to the initial risk of the bank’s client, is determined.

Published: February 2021

The article is aimed at forming an idea of the coevolution process as the basis for managing the economic security of enterprise. It is noted that the current state of development of socio-economic systems, which include enterprises, are at the stage of post-industrial development. The development of any enterprise depends on its ability to adapt to changes in the exogenous factors of influence, which causes rethinking and the novel approaches to managing the economic security of individual enterprises as preventive measures for adaptation. At that, economic security management should be considered taking into account significant changes closely related to the coevolution process, which has its origin in biology and is understood as a mutually agreed action to change the elements that constitute the integrity of the developing system. It is noted that during the end of the XXth century - begin of XXIst century a transformation of the development of socio-economic systems took place, changing from industrial to noosphere, with its central element being the human, and the central scientific platform for research being the economics of knowledge. Under these conditions, coevolution is considered as the basis for managing the economic security of enterprises with the definition of purpose, objects and subjects of economic security management, with specific provision of the management system and the formation of appropriate management principles. The central element of the economic security management system of enterprise is approaches to management on a coevolution basis, the formation of which is based on the synthesis of general-basis and specific management approaches, namely: evolutionary, systemic, resource, resource-functional. The result of the proposed aspects is obtaining a more effective result from the process of managing the economic security of enterprises.
Assessing the Operation Security of Trade Enterprises in the Modern Business Environment
Authors:   Kharkiv State University of Food Technology and Trade, Mukhina M. M.
Published: February 2021

The article explores the features of assessing the operation security of trade enterprises in the modern business environment. It is proved that the combination of different methods of situational analysis, e. g. SWOT and PEST methods, allows expanding the external and internal factors under research, which can be taken into account within a diverse range of possible management recommendations. Monitoring of key factors of SWOT analysis allows to develop efficient anti-crisis management strategies that ensure the constant readiness of enterprises to the onset of a crisis, and to adjust them in accordance with changes in the external and internal environment. An improved approach to monitoring the internal and external environment of enterprises based on the integrated use of both SWOT and PEST analysis techniques allows timely detection of crisis situations with adjustment of development strategies. It is proved that precisely the innovative factor is dominant in shaping the trajectory of economic development of trade enterprises. This determines the possibility of moving to a qualitatively new level of development, which, in turn, requires conscious and purposeful management of financial security at the enterprise. The matrix of financial stability of the trade enterprises’ activities is constructed. Four areas of the matrix are distinguished: stable operation area; active development area; sustainable development area; unstable operation area. It is recommended to take into account in the areas of the matrix the wear coefficient of fixed assets, due to the eventual situation when the wear coefficient of fixed assets should be reduced to increase stability. This is suggested to be displayed using a vector directed towards the beginning of the coordinates.

Authors: Makamure Chipo , Tsakeni Maria
Published: February 2021

The closing of schools due to Covid-19 has brought a dimension of uncertainty into STEM education. Despite the closing of schools due to the need to observe physical distancing, some schools have found ways to continue teaching and learning on virtual platforms enabled by increasingly pervasive fourth industrial revolution environments. In this study, the teaching of Ordinary level mathematics and science in pursuit of STEM education goals as enabled by the Internet of Things (IoT) in online classrooms was therefore, explored. Using an interpretive case study, relevant data were collected from two mathematics and three science teachers during semi-structured interviews. These participants communicated their experiences in transitioning from face-to-face to online classrooms as they worked to promote STEM education during the Covid-19 pandemic. The findings reveal teachers’ experiences of this transition and their selection of particular Web 2.0 tools to establish online classrooms. Notably, mobile instant messaging tools proved to be a popular option for being cheap, user-friendly, temporal, and multimodal. The findings also revealed that teachers struggled to adapt the hands-on activities to suit online teaching resulting in the use of teacher-centred approaches.

ASSESSING PRE-SERVICE TEACHERS’ RECEPTION AND ATTITUDES TOWARDS VIRTUAL LABORATORY EXPERIMENTS IN LIFE SCIENCES
Authors: Penn Mafor , Mavuru Lydia
Published: February 2021

This research reports the assessment of pre-service teachers’ reception and attitudes towards virtual laboratory experiments in Life Sciences with the aim of advancing adaptability to digital learning. Using sequential mixed-methods in a quasi-experimental design, 68 pre-service teachers in the 3rd year of a Bachelor of Education (B.Ed) program were surveyed before and after virtual learning interventions. This phase was followed by qualitative data gathering using focus group interviews with all participants. Findings from quantitative data analysis revealed a positive significant difference in pre-service teachers’ attitudes towards virtual laboratory experiments post learning interventions. From qualitative data pre-service teachers found the progression from using only traditional to including virtual experiments was useful in enhancing their conceptual understandings of Life Sciences concepts, convenience, inquiry-based learning, self-directed and autonomous learning. However, pre-service teachers noted that using virtual laboratories did not significantly develop their science process skills and as a result could not replace the experiences in a traditional biology laboratory. The implications of these findings project virtual laboratories as a supporting tool for experimentation in Life Sciences especially within and post the COVID-19 pandemic where issues of social distancing pose a threat to collaborative and inquiry-based science learning. Recommendations from these findings are discussed herein. Keywords: inquiry-based learning, life sciences, pre-service teachers, virtual laboratory experiments

Twenty-two genotypes of maize parental line were grown during 2017-2018 at the Research field of Plant Breeding Division, Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Rahmatpur, Barisal, Bangladesh. The experiment was laid out in randomized complete block design with three replications. Heritabilty, coefficients of variability and genetic advance values were computed for days to tasseling, days to silking, days to maturity, plant height (cm), ear height (cm), cob length (cm) and diameter (cm), number of seed rows per cob, number of seeds per row, number of seeds per cob, thousand grain weight (g) and yield (g/plant). Among all the traits higher phenotypic coefficient of variation (44.53) and genotypic coefficient of variation (44.18) were observed for yield/plant. The uppermost heritability was observed in case of yield per plant (98.41) followed by 1000 seed weight (96.91). Genetic advance was highest for seeds/cob (197.87) followed by 1000-kernel weight (176.86).Greater magnitude of heritability coupled with higher genetic advance in characters under study provided the evidence that these plant parameters were under the control of additive genetic effects. Indicating that selection should lead to a fast genetic improvement of the material.

Published: February 2021

An attempt was made to evaluate the contamination status of surface water collected from the Balu river for irrigation. Twenty samples were collected to analyze pH, EC, TDS and ions. Samples were slightly alkaline in nature. Water samples were from low to medium salinity and low alkalinity hazards (C1S1-C2S1). As per TDS values, samples were classified as freshwater. Considering SAR and SSP values, samples were excellent and good to permissible classes, respectively. Most of the water samples were free from RSC and all the samples were under moderately hard. The status of Cr and Mn ions in samples surpassed FAO guideline values indicating contaminants for long-term irrigation. The levels of other metal ions in samples were within acceptable levels and did not pose a threat to irrigated soil. This finding revealed that Cr and Mn ions were considered as contaminants in river water for irrigation posing harmful impact on soils and crops.

Published: February 2021

The research was conducted to collect information on the status of farming and marketing of live pangas (Pangasius hypophthalmus) from Trishal region to different areas of Bangladesh by interviewing stakeholder and secondary sources. The survey was carried out for seven months from May to November, 2016. Pangas farmers, arotdar, commission agents, wholesaler and retailers were interviewed in accordance with participatory rural methods. The results showed that the best harvesting season were found to be June to July and November to January. It was also found that 90% farmers harvested their fish completely and only 10% of farmers harvested partially. The price of pangas depends on market structure, quality, size, distance, weight, seasonal variation and regional perception. The prices of pangas were found to be highest of 130tk/kg and the lowest of 85tk/kg but sometimes 60 to 70tk/kg when the fish are dead (on the way to destined area) in different districts. On the other hand significant quantity loss was observed in fish 8%, 10%, 15%, 18%, and 19% after reaching to Savar, Manikgonj, Maowa, Sylhet, and Barisal from Trishal. Therefore, it was strongly recommended that proper handling of live fish must be ensured during transportation to attain quality pangas at consumer level.

Widespread groundwater arsenic contamination in south, south-western and north-eastern regions and high salinity in the south-western coastal region are the two major challenges for drinking water supply in Bangladesh. In this study, we assessed various water supply technologies used for mitigating arsenic and salinity in Laksam of Cumilla and Assasuni of Satkhira district. Water samples were analyzed for Arsenic, Iron, Chloride (indicator for salinity) and FC from different water extraction systems (shallow, deep and Tara tubewells), groundwater arsenic treatment units (SIDKO and READ-F), rainwater harvesting systems (RWH), pond sand filters (PSF), and managed aquifer recharge units. Most shallow tubewells, both in Laksam and Assasuni, have been found to produce arsenic contaminated water. But water from deep and Tara tubewells have been found arsenic-free, though high concentration of iron was observed in the wells in Laksam. Rainwater harvesting systems, PSF and MAR units in Assasuni have been found to provide water free from the common chemical contaminants but suffer from high bacterial contamination. Deep tubewell appear to be the most preferred option where a suitable aquifer is available. The community-scale groundwater treatment systems would require strong operation and maintenance support from the service providers to be successful.

Manganese (Mn) as an essential plant micronutrient affects plant development, when at deficient or toxic levels. Manganese is used in several biological processes as an important contributor in plant growth and development. Manganese uptake depends on forms of Mn in soil solution, crop characteristics including growth rate, and ineteractions with other environmental factors. Its distribution in soils and requirement for crops vary from location to location, depending on soil type and reactions. Despite the metabolic roles of Mn in different plant cell compartments, the importance of Mn requirement in plants, distribution in soils and application to crops has been understated. As a micronutrient, judicious Mn management requires to critically evaluating its concentration in soils, biochemical functions, critical levels, soil availability and interactions with other nutrient elements is essential. This review has critically analysed the existing body of knowledge on Mn distribution in soils, dynamics, functions and management towards better crop production and safe environment.

Program Pengabdian pada Masyarakat (PPM) yang dilaksanakan bertujuan untuk menerapkan multimedia sebagai media pembelajaran. Media pembelajaran yang dibuat adalah film animasi 2D Vector dengan latar cerita bencana alam di Indonesia (tsunami, gunung merapi, dan longsor) dengan nilai-nilai islami di dalamnya. Pemutaran film animasi ini membuat anak-anak menjadi lebih mudah untuk memahami musibah dalam bentuk bencana alam seperti apa dan sikap bagaimana yang perlu diambil sebagai seorang muslim. Anak-anak pun termotivasi senantiasa mengingat doa yang sudah diajarkan di Tempat Pembelajaran Quran (TPQ). Doa-doa tersebut dapat mereka panjatkan ketika terkena musibah, Film animasi ini dibuat dengan tujuan  agar anak-anak lebih mudah untuk ditanamkan sikap religius yang perlu diambil ketika mengalami musibah. Sehingga, anak-anak tidak berlarut-larut dalam kesedihan, tidak trauma berkepanjangan, dan dapat bangkit kembali untuk menata masa depan.  Film animasi ini juga dapat digunakan oleh guru maupun orang tua untuk memberikan pelajaran untuk membangun sikap religius anak agar anak mampu mengatasi musibah. Peserta sosialisasi terdiri dari anak-anak usia 5 sampai 12 tahun atau dinamakan kelas cabe rawit dengan jumlah siswa sekitar 12 orang per kelas serta 2 guru untuk tiap kelas. Kegiatan sosialisasi diadakan di TPQ Nurul Huda Dumai. Setelah kegiatan diharapkan anak-anak dapat melihat unsur edukasi pembelajaran nilai islami yang ditanamkan pada media film animasi 2D vector yang diperlihatkan.Kata kunci: animasi 2D vector, film, motion graphic
