Authors: TAŞĞIN Baran , İLBAŞ Mustafa
Published: December 2022

Increasing environmental concerns with climate change have led many people around the world to demand urgent action, forcing national governments to seek alternatives to carbon-based fuels. In the light of all this, it is of critical importance for our civilization that carbon-based energy sources are rapidly replaced by renewable and sustainable sources without carbon emissions. For this reason, the use of these clean energy sources and the efficiency of the processes in their production is a very important issue. In this study, 3-dimensional, two-phase (hydrogen and water) computational fluid dynamics (CFD) analysis was performed in a polymer electrolysis membrane cell (PEM). Analysis took place for 30 seconds. The water flow rate was kept constant at 260 ml/min. As a result of the analysis, pressure, gas volume fraction and velocity data in the manifolds and in the electrolysis channels where the electrolysis process takes place were interpreted. While the pressure change in the cell was quite high in the range of 0-1.8 seconds from the beginning of the flow, it was observed that a balance was formed in the pressure distribution after 1.8 seconds. It is understood that the number of channels in the model is a factor for the pressure inside the manifold and the cell. However, it was observed that the unit gas production amount in the cell also changed along the channels.

Authors:   Lviv Polytechnic National University, Krokhmalna Yaryna , Bortnikova Mariana ,   Lviv Polytechnic National University
Published: December 2022

Modern business trends create new requirements for the use of innovative tools for searching and generating ideas in order to increase the efficiency of enterprises. It is creativity that contributes to the personal and professional self-development and self-improvement of the company’s employees. Analyzing the research of recent years in the field of management, it can be emphasized that in order to achieve important organizational results, such as innovation, growth and management success, it is creativity that is important. Key industries in the creative economy include: advertising, architecture, arts and crafts, design, fashion, film, video, photography, music, performing arts, publishing, research and development, software, computer games, electronic publishing, television and radio. The era of informational and intellectual development became the era of the XXI century, which was marked by the transition from rationality to creativity. The concept of the “creative class” offers a new way of understanding the mechanisms of wealth creation. In the period of the “post-industrial” economy, the new driving forces of economic development are the “super creative core” (including artists, designers) and “creative professionals” (including managers, lawyers). Organizational management is complex and multidimensional in nature. It combines a number of elements, activities and processes aimed at achieving the organization’s goals. Amidst a rapidly changing business landscape, organizations are moving forward from the classic criteria of cost and performance to integrating creativity and innovation for overall efficiency. Such integration involves the study and implementation of concepts at different functional levels of management for the development of the creative potential of enterprises. Development of creative solutions at the enterprise involves market research and analysis, generation of new ideas, evaluation of alternatives and implementation of innovative solutions. Creative management is what is needed in the 21st century in order for the business to stay afloat and maintain its competitive advantage. The main skill that managers are looking for in skilled workers today is creativity. Creativity management ensures the development of an individual's creative skills, his ability to generate fundamentally new ideas and bring them to a concrete result. That is why the achievement of the goals and objectives of creative management requires improvement of the tools for the development and implementation of innovative solutions.

Published: December 2022

The article is devoted to the study of new technologies in warehouses; the essence of the “distribution channel” is considered through the analysis of the definitions of this term by various authors; the difference between the supply channel, the goods movement channel and the distribution channel was analyzed; the main changes and problems in the field of distribution over the past few years have been identified; describes the most innovative technologies for digitalization of warehouses. The results of the study showed that the implementation of the latest technologies in warehouses will ensure the coordinated and fast work of all its links. Thus, the new blockchain technology guarantees the sovereignty and protection of data transmission between the user and the company, as well as avoiding the reuse of certificates of origin through real-time tracking of goods. It is guaranteed through cryptography, visibility and data usage, as well as ensuring equal access to all network participants. This technology provides protection and, at the same time, openness of enterprise data, which in turn will help prevent unfair competition in the industry. The Pick by Voice technology will help to significantly increase the efficiency of warehouse workers, because the operator does not waste time reading, has free hands and is not distracted by related operations. The implementation of Radio Frequency Identification will help enterprises to maximally systematize information about the product itself, which in turn will improve and speed up work with both suppliers and customers. Also, the introduction of robotics in warehouses will ensure the minimization of the human factor at the workplace and the reduction of employee salary costs. In general, the advantages of implementing these technologies significantly exceed the disadvantages or risks. The main advantage is the smooth operation of the warehouse, reduction of production maintenance costs, systematized information and tracking of goods. The disadvantages are the costs of implementing these projections, which are quite expensive. Therefore, the development of online business and the reduction of delivery times to the shortest terms have started a trend towards automation of even small warehouses. In turn, warehouses with huge flows of goods need large-scale systematization of all processes, which is possible only with the use of the latest warehousing technologies.

Published: December 2022

The article presents the research results of the mechanisms of startups venture capital investment. The role and significance of venture capital investment in the startup ecosystem and the innovation ecosystem in general are considered. The economic essence of the concept of venture investing is presented. In the process of research, the peculiarities of venture capital investment for startups were analyzed and a comparative characteristic of venture capital investment and classical investment was given. Mechanisms of financing and support of innovative startups at different stages of the life cycle are analyzed. The main and auxiliary success factors of startups by stages of the life cycle are described. The research examines models of venture capital investment in innovative enterprises. In particular, the following options were considered: the model of capital transfer (partial participation), the model of joint investment and the fund of funds model. For each model, the implementation mechanisms of investing in startups are described and described schematically. Key stakeholders and all stages of the investment process are listed. The models of joint investment in startups are described, in particular the model of a public-private venture capital fund and the model of joint investment in a private venture capital fund. The three selected models have many common elements, but differ from each other in terms of their dependence on specific contractual mechanisms, financing and access tools, and in some cases, exit mechanisms from the investment process. They also differ in terms of overall complexity, with the “fund of funds” model being more complex than the other two models. When considering specific models of the organization of venture funds, the work used the practices and experience of a number of jurisdictions, including Australia, Israel, Tunisia and Great Britain. Recipients in the implementation of any of the considered investment models should be startups, academic spin-offs, technological enterprises at an early stage of development, innovative enterprises that carry out technology transfer. Projects may involve the development of new products or technologies or the expansion of existing operations to commercial scale.
Planning the costs of ensuring the quality parameters of the enterprise’s products in the conditions of foreign economic activity
Authors:   Lviv Polytechnic National University, Hryhoriev Oleksandr , Tuziak O. ,   Lviv Polytechnic National University
Published: December 2022

The problems of cost planning for ensuring the quality parameters of the enterprise's products in the conditions of foreign economic activity are investigated. The reasons for the introduction of key principles of quality management in the technology of planning costs to ensure the quality parameters of products are identified. Recommendations for the introduction of assortment policy planning based on the gradation of costs and quality parameters of products at the enterprise in the conditions of foreign economic activity are formed. Quality characteristic is a quantitative expression of one or more homogeneous indicators of products that meet the specific needs of consumers depending on its purpose and conditions of use. The ratio between the actually achieved quality indicator and its normative (reference) value determines the level of product quality. To justify quality indicators and determine their specific levels for each type of product, the following four factors should be taken into account: needs (preferences) of end users: citizens, processors, farms that use intermediate products; real opportunities to achieve quality indicators at this level of development of productive forces (equipment, technology, qualification of workers); availability of developed techniques, methods, ways of measuring quality indicators and monitoring their development; financial incentives for producers to achieve the best quality indicators and establishing financial responsibility for their reduction. The subjects of product quality planning are ultimately various measures and indicators that reflect both individual product properties and various characteristics of the quality management system and processes. One of the ways to improve the efficiency of economic activity of the enterprise is to further expand the range of products, which will help to increase the customer base, and therefore the level of sales. Also, expanding the range of products will help the enterprise to distribute risks and reduce dependence on business cycles. But it should be borne in mind that the expansion of the product range complicates the production process; when producing small batches of products, the cost of each product increases, the organization of management becomes more complicated. Therefore, in order to coordinate the interests of the enterprise – manufacturer and the market, it is necessary to clearly plan the range of products – both new and those already produced by the enterprise.

Published: December 2022

The results of the enterprise's economic activity are multifaceted and depend on many factors. Under such conditions, it becomes more and more difficult to evaluate the obtained results of the enterprise activity. This is especially difficult to do in the aviation industry, since the complexity of aviation equipment and the tragic consequences of its malfunction significantly complicate the calculation of the economic efficiency of the aviation equipment restoration. For a better understanding of the problem, it is necessary to comprehensively reveal theoretical approaches and identify the most important factors for evaluating the effectiveness of aviation equipment restoration. In order to solve the above problem, the purpose of the article is established as a study of the theoretical and applied principles of the effectiveness of the aviation equipment restoration. To realize this goal, the main tasks of the article are a deeper interpretation of the features of the concept of "efficiency", highlighting the views of modern authors on the issue and finding common denominators in their views, as well as developing a typification of the effectiveness of the process of restoring aircraft equipment by aircraft repair enterprises. The peculiarities of the definition of the concept of efficiency by modern scientists have been studied. The meaning of efficiency is revealed through profitability indicators. The interpretation of efficiency as a certain state of affairs has been studied. Features of the understanding of efficiency as a measure of achieving goals, the relationship between the established goal and the obtained results are highlighted. The approaches of scientists regarding the interpretation of the concept of efficiency are summarized, and also, taking into account the revealed features of the activity on the restoration of aviation equipment, the main provisions are formulated, which should be used as a basis for the formulation of the determination of the efficiency of the restoration of aviation equipment. The study of literary sources proved the existence of various types of efficiency. It has been established that efficiency, according to many scientists, is economic and social. The classification of the effectiveness of individual projects or types of activities was studied. Taking this into account, it is proposed to typify the efficiency of the process of restoration of aircraft equipment by aircraft repair enterprises in order to develop criteria and methods of its evaluation.

Published: December 2022

The article examines the trends in the development of venture business in Ukraine and examines its current state in the conditions of martial law. The main sources of funding for start-up projects were studied, the success stories of leading domestic start-ups were identified and analyzed, and the problems of the formation and formation of domestic start-up businesses were revealed. The authors analyzed the prospects for the development of the startup industry in Ukraine and the possibilities of its restoration to pre-war indicators. The article examines the essence and history of the introduction of venture investment mechanisms in Ukraine and identifies the peculiarities of the formation and development of domestic start-up companies. The authors analyzed the trends in the development of the venture capital market in the pre-war period in the segment of individual players of the investment market – joint venture investment institutions. The article defines the positions of Ukraine and its cities in the global rankings of the best ecosystems for startups and outlines the most popular high-tech industries for investors in local startup projects in pre-war times. The authors analyzed the branch-based local startups and investigated the profile types of the Ukrainian startup based on the criteria of the number of co- founders, duration of work on the market, sources of financing, level of profitability, and organizational forms of entrepreneurship. The article analyzes the factors hindering the growth of the national venture capital market and the development of the local startup industry, as well as highlights the priority areas of their support in wartime conditions. Many factors were added to the risks of innovative activity in the conditions of martial law startups, which disrupted the continuity and normal flow of business processes of national startup companies. The local startup community faced the problems of living in conditions of brutal hostilities, and therefore the issue of employee safety, their relocation to fairly safe places of residence, the relocation of valuable technological equipment, and servers, and the restoration of access to the Internet became the primary factors for the creation of startup teams and recovery. their work in war conditions. The suspension of funding of startup projects by foreign investors and the lack of own resources force emigrant startups and their employees with their family members to safe countries of the world, which is also a problem for the survival of the Ukrainian startup ecosystem.

During the last eight years, since the beginning of the Russian-Ukrainian war, some volunteer organizations that were created to help the Ukrainian army were able not only to expand their activities, but also to transform into charitable organizations with a defined management structure and areas of activity. In order to ensure the effective functioning of such entities, it is necessary to attract constantly financial resources, in particular, for medium- and long-term planning of their work. Fundraising is one of the ways to accumulate resources, particularly financial. There are various forms of co-financing and fundraising that strengthen the organization, including those ones engaged in foreign economic operations, both financially and contribute to the expansion of partnership. Therefore, modern volunteer organizations are a successful example of such tools implementation. In fact, funds are most often raised for charitable foundations, public organizations, etc. with the help of fundraising. However, in the modern realities of Ukrainian entrepreneurship, the use of fundraising tools can be used to preserve and develop the potential of domestic companies engaged in foreign economic operations in wartime. It was found that various scientists define the concept of fundraising as a complex system of activities or a method of communication. It has also been clarified which tools are used to implement the fundraising process within the framework of the activities of non-profit organizations and those engaged in foreign economic operations. Some peculiarities of fundraising activities in the United States of America were identified in terms of the high level of development of a democratic society, in particular, the importance of image, gaining customer loyalty, and holding physical events. By the way, an example of the successful attraction of financial resources by the charitable foundation “Povernys zhyvym” (“Come Back Alive”) as one of the most famous in Ukraine is given. Recommendations for domestic enterprises engaged in foreign economic operations seeking to attract financial resources for socially oriented projects are highlighted and listed.

Published: December 2022

The intensification of military and political instability and the activization of European integration processes necessitate the development and use of precisely urgent instruments at different levels and in different spheres. In the conditions of fulfillment of European integration obligations one of the priority directions requiring urgent reforms is the customs system of Ukraine. Along with the already implemented reforms in the customs sphere, there are still a number of unresolved tasks that require the introduction of effective and progressive tools. At the same time, the effectiveness of such tools is determined on the basis of a comprehensive information base, which is the result of a targeted assessment. Thus, an important problem today is the selection of a reasonable list of indicators to diagnose the optimality of customs urgent instruments to ensure the successful European integration of Ukraine. Indicators of evaluation of customs urgent instruments should be understood as measures of effectiveness of formation and use of customs urgent instruments at different levels in the context of urgent solution of urgent problems of customs nature, elimination or minimization of their negative impact, primarily on export-import operations of enterprises, increasing the favorability of customs services of foreign economic activity subjects and activation of international trade. In order to assess the effectiveness of customs urgent instruments for effective solution of urgent problems of the state customs system functioning and provision of its progressive development the system of diagnostic indicators was prepared based on a number of principles: purposefulness, urgency, anti-crisis, activation, relationship with stakeholders, multilevel orientation, the relationship with European integration, harmonization, specificity, adaptability, optimality, accessibility, effectiveness, information diversity. The developed typology of diagnostic indicators hierarchically differentiates such indicators to assess the impact of customs urgent instruments at different levels (mega-, macro-, meso- and micro-levels) of national economy in order to provide favorable customs services to enterprises as a precondition for enhancing export-import activities in the conditions of Euro-integration transformations.

On the way to European integration, Ukraine is facing many tasks related to the fulfillment of obligations under the Association Agreement with the European Union. One of the key places in the list of such tasks is harmonization of domestic customs legislation in terms of customs procedures with the norms of the European Union. In the context of assistance in solving this problem the essence and structure of customs procedures under the legislation of the European Union were studied. It was established that all customs procedures of the European Union are divided into three groups: release for free circulation, special procedures, export. The following special customs procedures are distinguished: transit (covers external and internal transit), storage (includes customs warehouse and free zones), special use (provides for temporary purpose and end-use), processing (includes processing in the customs territory of the European Union and outside the customs territory of the European Union). One of the most common customs procedures is the release for free circulation and export. The procedure of release for free circulation provides for: collection of duty; collection of other payments in individual cases according to the provisions of the relevant legislation, which obliges to pay them in such cases; application of trade policy instruments and prohibitions and restrictions, if they were not introduced in the previous stages; performance of other necessary formalities required when importing goods. As for the export procedure, it stipulates the following: all goods leaving the customs territory of the European Union must be placed under the customs procedure of export (only goods placed under the customs procedure of processing or transit may be an exception); goods exported outside the customs territory of the European Union are not the subject to customs duties; goods placed in the export procedure remain under customs control until they are in the customs territory of the European Union in the same condition as they were at the time of acceptance of the customs declaration; if the goods remain in the customs territory of the European Union, the exporter must promptly notify the customs authority.

Background: Every day, almost 20 million committed health care workers (HCP) are exposed to biological, chemical, and mechanical risks. According to the World Health Organization, nearly three million health care personnel are exposed to blood and other fluids each year as a result of needle stick or sharps accidents. Needlestick and sharps injuries (NSIs) are among the most common job-related injuries suffered by health care professionals. In fact, one of the most common occupational dangers among health care workers is the transmission of hepatitis B or C through work-related NSIs. Methods: This is a review is based on collecting all previous articles which were done on Factors association with needle stick injury: An Overview of Prevention & Management. Results: The review process involved determining the suitability of 20 publications. There were 20 papers that made it through the full text screening and into the final review. The purpose of this research was to assess Factors association with needle stick injury: An Overview of Prevention & Management. Conclusion: The findings indicated that no single device, place, or behaviours can be held solely accountable for all types of NSIs, although each can contribute to the injury. HCWs must use safety equipment more frequently, and training institutions with constant observation for procedures to reduce NSIs must be designed and implemented.

Authors: ALTUN Suat , KAPÇAK Veysel
Published: December 2022

The effect of a water repellent chemical used in the textile sector on some physical properties of wood was investigated in this study. Uludağ Fir (Abies bornmülleriana Mattf) and Beech (Fagus Orientalis Lipsky) were used as a wood and a commercial water repellent chemical named Ruco-DryEco® (RD), a fluorocarbon-free water-based product used in the textile industry, was used as a chemical. This chemical is used as an 3% aqueous solution in the textile industry. So, in this study 5% and 10% solution of RD was used. After the treatment with 5% and 10% solutions, the expected water repellency was not achieved and the study was repeated at 50% concentration. Weight percent gain (WPG), swelling effect (SE), water uptake (WU), water repellent efficiency (WRE), volumetric swelling (WS) and anti-swelling efficiency (ASE) values of the woods were determined and, were compared with the values of the untreated control samples. It was determined that, as the concentration of solution increases, WPG and SE values increase. In addition, the increase in impregnation time and the use of binders also cause a relatively small increase in WPG values. On the SE, it was observed that impregnation time was not very effective. The WU of the samples decreased slightly compared to the WU of the control group. The higher the amount of water repellent attached to the material, the lower the rate of WU. WS of all treatment groups was found to be less than that of the control group. However, the effect of the impregnation was found to be less with low concentration solutions. For both wood species, higher ASE values were obtained as solution concentration increased.

Indeed, the dam located in the village of Talembika in the municipality of Zam and the agricultural plain in Mogtedo are threatened by advanced siltation of the watercourse. This has an impact on the standard of living of the local populations. Can the cause of the silting be linked to a lack of communication on the management of water reservoirs? The main objective is to analyze the perceptions of the users of the dam on silting and the contribution of communication in the process of a good farming technique around the water reservoir of Mogtedo-Zam in the province of Ganzourgou in the Central Plateau region. To do this, quantitative and qualitative methods were used for the collection, processing and analysis of data using appropriate tools. The results of the study reveal rapid siltation of the dam, which is confirmed by 86.96% of the respondents. This situation is due to soil erosion, the deposition of solid materials from the watershed, high pressure from users, and low rainfall. Thus, communication is an important factor in the fight against siltation. The technical services are the first communicators of the users of the dam. Users lack information and awareness on the management of the dam and good farming practices to avoid its rapid siltation.

Insurance is one of people’s needs as a protection from the loss-causing risks. Based on the insurable interest, people then have an insurance agreement. The legal relation between an insurance company and the insured is based on a written agreement called a policy. In reality, not all claims can be done well. Insurance companies often fail to fulfill its obligation (payment failure), which is caused by several factors, including the allegation of frauds. This research is going to discuss the existence of insurance fraud as a factor in the case of payment failure of an insurance claim. The research employs a normative juridical method using the secondary data in the forms of primary legal materials such as relevant regulations, as well as secondary legal materials such as legal books and literature. The research uses legislation and conceptual approaches. The fraud factor is indicated if the element of intent can be proven when, in doing the transaction, the insurance company’s board has abused their authority, and when the transaction is proven to have influenced the company’s financial health.

The aim of the work is to determine the peculiarities of the clinical course of Wellens syndrome due to the presence of critical occlusion of the medial segment of the anterior interventricular coronary artery bifurcation.Material and Methods. Clinical manifestations of the disease, including dynamics of ECG changes; coronary angiography data; results of echocardiographic and laboratory tests.Results. This article presents the peculiarities of the clinical course of Wellens syndrome in patient L., 70, who met the currently recognized diagnostic criteria of the syndrome, but the critical occlusion of the anterior interventricular branch of the left coronary artery was localized in its medial segment. Along with this, there was hemodynamically irrelevant stenosis of the proximal coronary artery section (60%). Electrocardiographic changes were consistent with pattern B (deeply inverted T waves in V2-V6). Сonditional normalization of the T waves, indicating the absence of repeated coronary artery occlusion after spontaneous reperfusion. Stenting of the anterior interventricular coronary artery vein of the left coronary artery prevented the possible occurrence of “stuttering” pattern and the occurrence of myocardial infarction.Conclusions. Acute coronary syndrome with complete coronary artery occlusion is often accompanied by spontaneous reperfusion, which contributes to the relief of chest pain and the appearance of characteristic T waves on ECG and is the basis of the so-called Wellens syndrome. The most frequent localization of coronary artery occlusion is the proximal segment of the anterior interventricular branch of the left coronary artery, but we witnessed the occlusion in the medial segment of these coronary arteries. Immediate coronary angiography with stenting of the occluded artery will prevent the occurrence of myocardial infarction in the patient.

The aim to evaluate the possibility of determining the optical density of venous blood plasma (ODVBP) to identify the viability of the intestines in the experiment.Material and methods. For the study, 30 nonlinear white rats were used. In 10 animals, the loop of the middle part of the small intestine was tied with a ligature to simulate destruction, and in 10 animals, the loop of the middle part of the colon was ligated. After 12 h, a laparotomy was performed, the ligated loop of the intestine was removed for histological examination and blood was drawn from the jugular vein to measure ODVBP. The control was given to 10 healthy animals.Results. Healthy animals at a wavelength lambda = 310 nm found a specific maximum ODVBP, reaching 0.22 units (0.22 ± 0.01). After 12 h in animals with models of small bowel destruction, the ODVBP values at this wavelength were 0.38 ± 0.17 units, which was statistically significantly (p <0.01) higher than the control values. In animals with models of colon destruction, the indicators of ODVBP at this wavelength were 0.37 ± 0.13 units, which was statistically significantly (p <0.01) higher than the control values. There were no statistically significant differences between the indicators of animals with models of destruction of different parts of the intestine (p> 0.05). Necrotic changes of the intestinal wall were detected on all histological preparations.Conclusions. 1. According to experimental data, in healthy rats at a wavelength lambda = 310 nm, there is a peak ODVBP, reaching 0.22 ± 0.01 units. 2. In animals with models of destruction of the small intestine, the rate of ODVBP at this wavelength increases to 0.38 ± 0.17 units, and in animals with models of destruction of the colon - up to 0.37 ± 0.13 units, which is statistically significant (p (0.01), exceeds the control values, at the same time there are no statistically significant distinctions in different localization of intestinal destruction (p> 0.05). 3. The data obtained indicate the prospects for clinical use of such an index to assess the condition of the intestines under conditions of their destruction and the need for appropriate clinical trials.
