The Impact of Blockchain Technology on the Financial Sector of the Global Economy
Authors: Shevtsova Alina V. ,   V. N. Karazin Kharkiv National University
Published: July 2024

The aim of the article is to highlight the importance and relevance of blockchain technology for the financial sector of the global economy, as well as to find out how blockchain technology affects security and reliability in the financial sector, simplifying the processes of exchanging assets and making transactions; emphasizing the importance of blockchain technology in improving the settlement system, reducing time, and increasing market liquidity. With rapid technological development, the role of blockchain technology is growing as a key factor determining new directions for the financial sector. Since its emergence as the foundation for cryptocurrencies, blockchain has quickly evolved from an alternative concept to a powerful tool that has the potential to change the paradigm of how financial services work. Outdated methods of providing financial services have long been in need of revision. Challenges such as data entry into various systems and manual processing of information are becoming increasingly common in the financial sector. The centralized model is becoming increasingly vulnerable to cyberattacks, as all data is concentrated in one place. Consequently, to date, outdated methods of information systems and the workload of paper documents in the financial sector have proven to be not only ineffective, but also vulnerable to security risks. These problems arise from deficiencies in centralized systems that store and process sensitive information. Lack of transparency, the possibility of errors, and suspicion about security are obstacles to the effective functioning of financial institutions. To solve these problems and improve processes, it is necessary to move towards digital innovations that promote collaboration, increase trust, independence and ensure a high level of security. One of the most promising technologies that meets these requirements is blockchain, which is based on a distributed data storage system and cryptographic principles, which can provide a high level of security, transparency, and authenticity of information. It avoids intermediaries by allowing direct collaboration between participants, and it also makes it possible to store and transmit data in a secure environment without the risk of their modification.

The aim of the article is to evaluate the indicators of the insurance market of Ukraine as part of the financial sector, analyze the patterns of its development and determine the impact of full-scale military operations on its dynamics. Analyzing trends in the development of the insurance market of Ukraine its active recovery in 2023 was noted as evidenced by an increase in gross premiums by 18.7% and the number of concluded insurance contracts by 7.6% compared to 2022. The article evaluates the structure of the financial sector of Ukraine, defines the place and role of the insurance market. It is revealed that the financial sector of Ukraine is dominated by banking institutions which have increased the volume of their assets over the past 7 years more than 2 times, at the same time, the insurance sector has increased its portfolio of assets by only 29.4%. An analysis of the depth of the insurance market was carried out through the indicator of the level of insurance penetration the value of which reaches 0.8% at the end of 2022. It is noted that in Ukraine, unlike the developed countries of the world, the insurance market is characterized by the dominance of risk insurance companies, the size of their assets significantly exceeds the assets of life-insurers. Along with that, during 2021–2023 life insurance companies have significantly increased their asset portfolios. Quantitative parameters of the insurance market of Ukraine were monitored and it was found that insurers receive the most premiums from automobile types of insurance – about 50% of all premiums, personal types of insurance provide slightly less than 30% of premiums. A list of conditions that would allow insurance companies to more effectively meet the requirements of consumers of insurance services is given. Prospects for further research in this direction are the study of theoretical and empirical aspects of the relationship between the indicators of the insurance market and economic growth.

Published: July 2024

The article discusses the transformation processes that have taken place in the management of enterprises in extremely changing conditions of their functioning, which is war. For sustainability and development, these processes require, in particular, rapid adaptation, revision of the following: paradigms of management, security, personnel policy, information flows, business processes and business models; implementation of the principles of inclusiveness and accessibility, cost optimization; introduction of modern digital technologies; increase of productivity. The aim of the article is to substantiate and systematize the transformation processes of enterprise management during the wartime. To achieve this goal, the following tasks have been performed: the main problems in the management of enterprises that hinder their development in wartime have been systematized and characterized; the main blocks that unite the transformation processes in the management of enterprises during wartime are allocated on the basis of an analysis of the experience of various Ukrainian and international companies, this will allow other economic entities to lead their enterprises to sustainability, success, and efficiency. As result of the study, the authors determined that the main challenge in management in peacetime and in wartime is the rapid variability of factors of external influence, which leads to ultra-risky managerial decisions. During the war, it is difficult to foresee all sources of risks in management decisions that affect the business processes of the enterprise. At that, challenges appear quickly due to the variability of external factors, which leads to the rapid adaptation of managerial decisions and the need for their urgent solution. The loss of planning ability directly affects the decrease in the efficiency of the enterprise. Therefore, enterprises are trying to form certain patterns to stabilize their activities in extremely changing conditions of their functioning. Obviously, management has become the key instrument in this. The ability to make management decisions quickly, adapt to changing external factors, and implement high-quality communication with the team are crucial for success. Despite the lack of a one-size-fits-all approach, adhering to these core principles helps leaders navigate wartime and lead their businesses to sustainability, success, and efficiency.

Corporate culture turns out to be especially important for companies during the wartime, when changes in the economic and social environment can be radical and rapid. Corporate culture determines the values, norms of behavior and ways in which employees respond to stressful situations that become critical in times of uncertainty and crisis. Culture fosters team cohesion by helping to counter internal conflicts and providing like-minded people in making important decisions for the company. A robust and supportive corporate culture can keep employees morale, motivated, and productive even in challenging environments. In addition, corporate culture influences the perception of the enterprise by external stakeholders, including customers, partners and investors, which can be of great importance in times of crisis. Corporate culture builds the image of the business, increases trust and helps to maintain positive relationships with stakeholders, which is important for maintaining stability and long-term success of the enterprise. The importance of corporate culture in the context of military conflicts and crisis management has been verified by the research of many scholars and researchers in the field of management and psychology of organizations. Research in the field of management and organizational behavior confirms that corporate culture can be transformed during crises and wars. For example, under the influence of stressful situations, the values and norms of the organization can be re-evaluated, the emphasis in communication and activities shifts depending on the circumstances. Such a transformation of corporate culture can reveal both positive and negative impact on the organization during crises and war. On the one hand, it can stimulate innovation, change of strategies and approaches to problems, which is important for the survival of an enterprise in difficult conditions. On the other hand, a change in corporate culture can generate internal conflicts, impair communication, and increase risks for the organization. Thus, management and control over the process of transformation of corporate culture is a key aspect of effective crisis management. However, this aspect requires further research and clarification of management strategies, since the impact of corporate culture during a crisis can be diverse and require specific approaches for each situation. Additional research will help unleash the potential of corporate culture in crisis management and develop effective strategies to ensure the stability and success of the organization even in the most difficult conditions.

Published: July 2024

The aim of the article is to define a system of indicators for assessing the provision of sustainable development of enterprise, strengths and weaknesses in the existing practice of its functioning in order to further form a development strategy. The article examines the issue of assessing the provision of sustainable development of enterprise, which is a key aspect of modern business management. Sustainable development of an enterprise encompasses economic, ecological and social aspects that must be harmoniously integrated to achieve long-term stability and competitiveness. The author analyzes various methodological approaches to assessing sustainable development, including such quantitative and qualitative indicators as sustainability indices, environmental and social reports. The aspects of assessing the effectiveness of the enterprise’s functioning through the system of assessment of the economic, social and ecological components of sustainable development are considered. Methods and instruments for sustainable development management have been developed, enabling identication of the sources, essence and directions of change to ensure sustainability. The definition of the category of «sustainable development management mechanism» has been clarified. It is determined that one of the important instruments is to conduct independent audits, which allow to assess the compliance of the enterprise’s activities with international standards of sustainable development, such as ISO 26000 (social responsibility) and ISO 14001 (environmental management). Such inspections help to identify obstacles and define areas and tools for improving the performance of the enterprise. Particular attention is paid to the role of strategic planning and resource management in the context of sustainable development, as well as the influence of external factors such as legislation and market conditions. As a result of the study, a system of indicators for assessing the sustainable development of enterprise has been proposed, including indicators of economic efficiency, environmental responsibility and social justice. Conclusions and proposals should be used in the work of managers and researchers interested in the implementation and improvement of sustainable development strategies in enterprises.

The article analyzes the international experience of convergence of regional development. The features of the European development of regional policy are defined. The main stages of formation of regional policy of some European countries have been allocated. It is substantiated that the change of the conception of the Europe of nations into the conception of the Europe of regions has led to the formation of a single market, in which the regions are considered as independent players due to increasing their competitiveness. The main tasks of regional development support funds in European countries have been formed. It is determined that on the basis of support and implementation of socioeconomic reforms, introduction of innovative technologies, an increase in the competitiveness of regions and an increase in the level of employment of the population has been achieved. In developed countries, programs are being developed to improve energy infrastructure, which include the development of alternative energy, the introduction of energy-saving technologies, and the creation of new energy communications. It is determined that in regional development an important role is played by stimulation of medium and small businesses, which is implemented on the basis of support of such initiatives by providing them with simplified access to capital, activation of enterprises engaged in tourism activities. It is determined that, despite the different levels of regional development, the main vector is the creation of prerequisites for the balanced development of all territories through minimizing the impact of negative environmental factors. The main instruments for ensuring the convergence of regional development have been allocated. The policy of France in the direction of stimulating the convergence of regions, which consists in the State-controlled system of contracts for planning regional development, is substantiated. The regional development policy of the Netherlands and Austria is more focused on the development of instruments of influence. The peculiarity of the Danish system of regional development is the refusal to stimulate and support certain problem regions and the application of a market approach, which is aimed at creating the necessary conditions for their independent development. The features of the policy of regional convergence of the USA, China, Canada and Australia have been studied, which allowed to allocate the features of their policy of stimulating the development of territories. The main aspects of the formation of regional development policy in Ukraine are also examined and the priority tasks in this aspect are allocated.

KARMA SEBAGAI PRAKSIS PEMBEBASAN DALAM BHAGAVAD GĪTĀ
Authors: Arta I Gede Arya Juni
Published: July 2024

This research is a literature study, using qualitative data. The hermeneutic method was used to analyze data regarding the teaching of karma as a practice of liberation in the text of the Bhagavad Gītā. Where, the Bhagavad Gītā has an important position in Hinduism because it contains the teachings of Brahmavidyā (divine knowledge) and yogaśāstra (yogic knowledge). The Bhagavad Gītā not only guides humans ethically, but also directs humans to carry out practical actions through karma (effort, work, action). In this case, the Bhagavad Gītā makes karma a praxis through the teachings of yoga, as a way to connect oneself (individual soul) with God (Universal Soul). The teaching of karma in the Bhagavad Gītā emphasizes work or actions carried out based on dharma (duty), and awareness of God as the owner of actions (karma). In this case, all the actions he performs will be directed towards God, so that he will no longer be bound by the results of the actions he performs. This is expressed in the Bhagavad Gītā, II.47: karmaṇy evadhikāras te mā phaleṣu kadācana, mā karma-phala-hetur bhūr mā te saṅgo ‘stv karmaṇ. The result of this research is that the Bhagavad Gītā teaches karma as a path to material and spiritual liberation. Where material liberation is interpreted not as an effort to accumulate material possessions, instead it frees humans from the shackles of material attachment by offering all the results of actions or work to God. Complete surrender to God of all karmic results and Unity with God is a form of spiritual liberation.

The implementation of an open economic system in Indonesia since 1969 has significant impact to the national economic growth. The high demand and supply of goods from within the country involved in international trade demonstrate a close correlation between export and import activities with the exchange rate of the rupiah. Economic stability is measured through the stability of the rupiah exchange rate against foreign currencies. The balance between demand and supply in the global market is considered crucial for creating a stable economy. History has recorded the Indonesian economic crisis in 1998, where the exchange rate of the rupiah against the US dollar drastically raises and causing challenges to the domestic production cost. This research aiming to make predictions using data science approach based on historical (time series) data. GRU, LSTM, and RNN algorithm being assess to perform the prediction. Results show that RNN algorithms generally outperform GRU and LSTM in making the prediction, particularly with limited time series data. Although RNN is typically superior, in one instance, GRU achieved slightly higher accuracy (0.047% difference) for the CNY to IDR pair over five years. Furthermore, the research highlights the substantial impact of batch size on algorithm accuracy, considering external factors such as interest rates. These findings offer valuable insights for economic decision-making and policy formulation.

This study uses a quantitative methodology and machine learning methods, namely k-means and k-medoids algorithms. These two methods will be compared to determine which is the most effective for export and import data of goods in Indonesia in 2021-2023. The results of the study were obtained by K-Means more effectively in handling data on the grouping of exports and imports of goods in Indonesia in 2021-2023. The dataset shows the results of the evaluation of K-Means using DBI of 0.59, while the results of the evaluation using K-Medoids show a result of 1.7868. Because the evaluation value of K-Means has low computing performance compared to K-Medoids.  The largest amount of the value and weight of exports and imports of goods in Indonesia is in C1 where in the HS code [27], namely Mineral fuels with a total export value of goods in 2021 to 2023 of 134,999,470,522 US$ and a total import value of 113,714,568,740 US$. Meanwhile, the total export weight of goods from 2021 to 2023 in mineral fuel goods is 1,505,006,250,327 Kg or around 1,658,985,413 tons and the total import weight is 186,446,782,134 Kg or around 205,522,397 tons.
Flowing Body: The Collision of Power Relations, Mind and Body Agency
Authors: Li Yuchen
Published: July 2024

This article constructs a novel theoretical framework for understanding the body in feminist theory by critically engaging with existing non-binary and non-essentialist views. It advances upon foundational critiques, particularly those by Haraway, Connell, and Butler, integrating the dynamics of body agency, power relations, and mind to propose a more fluid and intersectional approach to body politics. The new framework posits the body as an active participant in its continuous formation, interacting with and reshaping societal norms and expectations. Empirically, the paper analyzed four artworks displayed in art galleries and museums in Lund and Malmö in Sweden as case studies, focusing on how these works represent and shape notions of the female body across various themes including beauty, reproduction, migration, and sexuality. These artworks serve as a medium to explore how corporeal experiences are constructed through the interplay of power relations, mind, and body agency. Through critical analyses of theory and textual analyses of artworks, this paper points out that the body is a language of fluidity, simultaneously influenced and shaped by power relations, the mind, and its agency. Feminism should treat the body more carefully, avoiding biological essentialism or absolute social constructs.

Farm sabotage can cause massive fish escape events with significant ecological and socio-economic risks. This study examined the fate of Mediterranean seabass Dicentrarchus labrax escapees following a large-scale escape event caused by sabotage in the Western Mediterranean Sea. We monitored the escapee density and size structure over 3 mo after the escape at increasing distances from the escape point, up to 45 km away. Fish density adjacent to the escape location 5 d after the sabotage was, on average, 114 ± 44.7 (SE) fish per 100 m2. Our analyses showed that fish density decreased by 17% for every km away from the location, dropping to 2 and 1% after 1 and 2 mo, respectively, following the escape event. As escapee density declined throughout time and space, the size distribution of seabass shifted towards larger sizes. The rapid decrease in fish densities highlights the need for contingency plans focusing on fishing efforts in the coastal areas near the escape location (<20 km) within the first 24 h. These results are paramount to mitigating the risks associated with escape events cost-effectively. We emphasise the importance of sabotage prevention measures, such as security systems that can quickly detect intruders and trigger an immediate response to deter them. Additionally, enforcing appropriate sanctions based on the severity of the damage caused could help to discourage future sabotage attempts.
Harmonizing and Optimizing CT Perfusion Stroke Imaging
Authors:   , Peerlings Daan
Published: July 2024

This thesis focuses on harmonizing and optimizing CT perfusion (CTP) imaging for stroke. CTP imaging can help select patients with ischemic stroke for thrombectomy. However, due to a lack of consensus on the CTP acquisition and processing protocols, widespread acceptance of image-based treatment criteria has not been achieved. The CLEOPATRA care assessment was set up to determine whether it is cost-effective to select patients with ischemic stroke for thrombectomy based on stroke imaging. We focused on harmonizing and optimizing the protocols for CTP stroke imaging.
Chapter 1 introduces some concepts of CTP imaging. In CTP imaging, contrast agent is injected into the bloodstream. By measuring changes in contrast enhancement over time, perfusion maps can be created. These perfusion maps show the blood flow in brain tissue and are used to estimate ischemic (less perfused) brain regions. The estimated ischemic regions help clinical decision-making for ischemic stroke.
Chapters 2 and 3 discuss the injection protocol, scan protocol, and processing protocol of CTP imaging. Using an anthropomorphic digital CTP phantom, we argued that the processing protocol has the greatest impact on CTP imaging results. Additionally, variations in the injection and scan protocols between centers can, in some cases, lead to different CTP imaging results.
Chapter 4 describes our efforts to create a physical CTP phantom from the digital phantom in chapters 2 and 3. By scanning paper sheets printed with contrast agent, we demonstrated that simulating anthropomorphic brain tissue perfusion with a physical phantom is feasible.
Chapters 5 and 6 cover the estimation of ischemic regions. A standardized method that we developed could harmonize and optimize CTP imaging results to some extent. Additionally, the estimations from this standardized method resembled both manual segmentations of CTP perfusion maps and acute MR diffusion images.
Chapter 7 presents a new use of CTP imaging as a tool to locate vessel occlusions. Smaller and more distal occlusions are increasingly difficult to locate with CT angiography imaging. We demonstrated that the location of the total ischemic region, determined from CTP imaging, can help locate the vessel occlusion.
Chapter 8 recommends establishing a standardized framework for estimating ischemic regions to reduce inconsistencies in clinically relevant information derived from CTP imaging. Based on our research, this framework should utilize all perfusion data, consider spatial information, and rely on manual segmentations as a reference point.
In summary, we believe that CTP imaging remains important for helping patients with ischemic stroke. This thesis argues that current inconsistencies arise from misinterpretations of perfusion maps. We advocate for a shifted perspective in which CTP imaging is assessed on its intrinsic value and broader clinical applications are considered. Only then can the full potential of CTP imaging be realized.
Nature and Challenges in the Teaching of Anatomy from a Global Perspective
Authors:   , Chang Chan Ana Yoe Cheng
Published: July 2024

Human anatomy has played a central role in the evolution of medical sciences. During the 20th century, several changes occurred in anatomy in both science and education.

To meet current health needs, low-and-middle-income countries (LLIMC) are challenged to provide quality medical training to more students while maintaining the same number of qualified teachers and teaching resources.

This thesis delves into the subject of optimizing anatomy teaching from a global perspective, addresses disparities between high-income and low-middle-income countries, and offers practical insights into how LLMICs teach anatomy.

The following studies were conducted:
- A study about where we are and where we are going in teaching anatomy based on the experience and views of medical educators from a developed country.
- Two field investigations addressed implementing technology (E-learning) and applied anatomy (radiological anatomy) in anatomy teaching in an LLIMC.
- A comparative study to understand the cultural and economic differences and similarities between high (Netherlands) versus low (Nicaragua) countries and the preferences of their medical students regarding anatomy education.
- A literature review to identify the available evidence on approaches to anatomy teaching in LLMIC.
- An international study involving anatomy teachers from several LLMICs to explore the challenges and strategies they have implemented.

Anatomy's visual and practical nature allows effective horizontal and vertical integration (particularly with radiology). In academic settings with limited resources, teachers' and students´ commitment and motivation appear vital to the development of medical sciences. Visual learning, applied anatomy, and communication tools (WhatsApp) were the most viable strategies.
