Designing mechanisms to encourage immigrants for official employment in Ukraine
Authors: Kostennikov Dmytro
Published: December 2023

This article offers an original perspective on the issue of incentivizing immigrants for official employment in Ukraine to support post-war reconstruction efforts. The proposed solution is viewed from the perspective of motivation and the organization within host communities. It’s evident that post-war Ukraine will require non-standard regulatory measures, as all neighboring countries are implementing similar strategies. This article aims to substantiate the organizational integration and motivational mechanisms for encouraging immigrants to engage in official employment in Ukraine as an urgent and strategically significant tool for implementing state immigration policy. The conclusion is drawn that in the context of intensified European integration efforts, we must also focus on areas beyond legislation. This includes education, employment opportunities, the establishment and operation of foreign companies in Ukraine, and attracting foreign workers through mechanisms such as language barrier improvement, recognition of foreign qualifications, skills enhancement, and improvements in social security and guarantees. Specifically, we should intensify: (a) development of attractive investment programs and financial incentives to attract Ukrainian expatriates and highly skilled immigrants to participate in Ukraine’s recovery and development projects after the war; (b) creation of specialized legal and tax conditions for immigrants wishing to contribute to the development of critical sectors such as infrastructure, education, healthcare, and innovation; (c) accreditation and recognition programs for foreign qualifications and experience to facilitate immigrant integration into Ukrainian professional unions and civil organizations; (d) partnerships with Ukrainian and international companies to create jobs and support immigrants in adapting to the Ukrainian job market and way of life; (e) development of programs for immigrant families wishing to join Ukrainian society, including educational and medical services for children and other support to create a favorable environment for resettles. Unfortunately, discussing the foreign-qualified labor force policy in the near future is challenging due to the security situation across our nation caused by the ongoing state of war. Therefore, migration policy’s primary focus is working with domestic resources to prevent their outflow.

Published: December 2023

This article explores the legal role of digital systems in the institutionalization of public administration in the context of decentralization, with a focus on the role of artificial intelligence (AI) in state management processes. The objective of the article is to define the legal role of AI and organized computer systems in state management processes and public administration. It identifies the factors that contribute to or hinder the effectiveness of integrating digital systems into legal institutions and relationships in Ukraine, with a specific determination of their distinct legal status. The research adopts a neo-institutional approach to analyze the legal institutionalization in various spheres of public administration.

The article examines factors and elements that limit the effectiveness of AI usage in legal institutions during the process of decentralization and redistribution of executive powers, as well as in building a new quality of interaction with citizens and civil society. This material can serve as a foundation for studying ways to intensify the involvement of AI-based engineering systems in legal institutions in various aspects of public administration.

Ukrainian scholars are encouraged to actively research the opportunities and challenges associated with AI implementation in public administration. Firstly, it is crucial to investigate the legal framework regulating the utilization of AI in state structures and institutions. Active collaboration with human rights organizations and other stakeholders is essential to ensure compliance with transparent and ethical standards in AI utilization in governance. Additionally, researchers should provide recommendations on establishing mechanisms for monitoring and auditing the implementation of AI to ensure its efficiency and compliance with legislation. Such an approach will contribute to the successful institutionalization of public administration using AI and promote the development of a modern and efficient system of state governance in Ukraine.

The article presents a review of foreign literature on the main approaches to protecting the health of the working population from the standpoint of industrial and restorative medicine. The article discusses the problems associated with psychosocial risks and stressful impacts at work / production, substantiates the need to implement measures based on the principles of prevention, recovery and rehabilitation. It is emphasized that today, requirements for working conditions, control over production processes, the relationship between requirements in the field of health protection of workers and their labor protection, as well as psychosocial factors - uncertainty at work, distracting breaks, lack of team spirit and etc. The policy of the enterprise, relevant industries, and the state itself in the field of protecting the health and life safety of workers is of decisive importance for the health of the working population. Teamwork involves not only the participation of health and safety employees, but also the employees and employers themselves at the respective workplaces / production sites, as well as the involvement of third-party experts. Sustainable employment of the working population is associated, according to scientists, with such aspects as maintaining and restoring the health of workers, economic productivity, social utility and a favorable long-term outlook. Problems of risks for workers require an integrated approach to the development of measures aimed at primary prevention, including the prevention of overwork, changing the style and organization of work, strengthening and maintaining health in general. An approach is considered important for preserving and restoring the health of the working population when it is advisable to combine measures for the primary prevention of health disorders not only with measures to optimize the organization and working conditions, but also with modern technologies of preventive and restorative medicine.

Published: December 2023

The problem of cardiovascular diseases, for example, atherosclerosis, justifies any attempts to identify the mechanisms of not only their formation, but also prevention and treatment, in particular with the use of drugs. In this regard, the purpose of the work was to study the possibility of using the dietary supplement Trekrevit during the treatment of patients with atherosclerosis with simvastatin. 45 men aged 22 to 35 years with signs of carotid artery sclerosis were examined. Patients of the main group, in addition to simvastatin, received Trekrevit for 10 months. It has been established that the addition of basic therapy with the dietary supplement trekrevit causes significant improvements in the characteristics of the walls of the carotid arteries in patients. It is also important that a previously unknown property of trekrevit has been established - to enhance and prolong the effect of simvastatin. This indicates the high effectiveness of combined treatment of patients with atherosclerosis.

The study optimized the analytical method for determining the active components of targeted drugs for the treatment of low-grade gliomas dabrafenib and trametinib, in a model organoid system. Third generation organoids were incubated for 24 hours in the presence of 100 μg/ml dabrafenib and trametinib (substance, SIGMA-Aldrich, Germany) (3 cultures in each series). The method for determining dabrafenib and trametinib in organoid tissue included sequential washing of tumor-like structures from the incubation medium, homogenization and centrifugation, followed by determination of the concentration of active substances in the supernatant by HPLC on a Shimadzu LCMS-8030 mass spectrometer (Japan) using a Phenomenex Luna® C18 column (2) 250 * 4.6 mm, with an internal diameter of 5 μm and a sorbent pore diameter of 100 Å. The release time (RT) of dabrafenib in these conditions was 7.405 minutes, the RT of trametinib was 8.356 minutes, the selectivity factor (α) was 1.19, which satisfied the requirements (α > 1). The chromatographic system resolution (Rs) was 2.13, indicating complete separation (Rs > 1.5). Thus, the developed method may be used to determine molecularly targeted drugs - dabrafenib and trametinib in model tumor systems.

Published: December 2023

Introduction. Cough, especially painful paroxysmal, significantly impairs the quality of life of the patient, disrupting his sleep and reducing physical activity. Herbal expectorants with a reflex action can significantly increase the volume of bronchial secretions that young children are unable to cough up on their own, which can lead to a significant impairment of the drainage function of the lungs. A combination of herbal expectorants with secretolytics will be very effective. The creation of combination drugs that simultaneously affect various pathogenetic mechanisms of cough is a promising direction in pharmacy. Therefore, the purpose of this study is to develop the composition of lozenges with expectorant and mucolytic effects that do not cause disruption of the drainage function of the lungs. During the study, were produced 9 ready compositions of a medicine, the quality of which was assessed in accordance with the requirements of the general pharmacopoeial article of the State Pharmacopoeia of the XIV edition according to the indicators: description, disintegration, crushing strength and grateness.

Published: December 2023

Coronary artery disease (CAD) is one of the most common causes of mortality both in Russia and worldwide, which necessitates the development of diagnostic methods for detecting and localizing pathology in coronary vessels at the earliest stages. Among the non-invasive diagnostic methods, one of the most common and effective is myocardial perfusion imaging using single-photon emission computed tomography (SPECT), which, however, only allows for semi-quantitative assessment. Quantitative assessment is possible using positron emission tomography combined with computed tomography (PET/CT), including the use of 82Rb-chloride as a tracer. The aim of this study was to evaluate the feasibility of applying the SPECT technique proposed by Ansheles et al. in 2015, for the detection of early perfusion abnormalities, analyze the results obtained, and determine the differences in the use of the 15-segment and 17-segment myocardial division schemes in PET with rubidium-82 chloride. Materials and methods: PET studies with rubidium-82 chloride were conducted on 10 patients with symptoms of CAD but without coronary artery stenosis according to coronary angiography. Perfusion severity indices and perfusion heterogeneity indices were calculated for each patient using both the standard 17-segment model and the previously proposed 15-segment model. Results: Statistically significant differences between the 17-segment and 15-segment models were only observed when assessing the heterogeneity index at rest; in other cases, no statistically significant differences were found between the two models, indicating the possibility of using the 15-segment model for calculating quantitative parameters. Both models showed a lack of correlation between perfusion severity indices during rest and stress studies, which may allow for the use of this index in evaluating the presence of microvascular abnormalities. No statistically significant differences were found between men and women in the analysis of these indices...
MOTIVATION THEORY: FROM HEDONISM TO THE DICHOTOMY OF INTERNAL AND EXTERNAL MOTIVATIONS
Authors: D.V. Bolbochan
Published: December 2023

Motivation remains one of the most studied topics in the field of psychology and management - many foreign and domestic psychologists throughout the 19th-21st centuries were interested in what exactly motivates people to act. The thinkers of Ancient Greece and Rome studied this issue, however, this area does not stand still, and over time, theories of motivation are developed and supplemented. The author of the article seeks to contribute to the study of motivation, starting from the philosophical concept of hedonism of the 15th century and to the division of motives into internal and external within the framework of motivation theories of the 20th century. The purpose of the article is to synthesize basic theories of motivation, starting with hedonism and ending with the dichotomy of internal and external motivations - the author explores various concepts of motivation and describes their influence on human behavior in the context of three related theories: Jungian orientation, self-determination theory and the theory of internal and external values. The study uses analysis and synthesis of scientific literature, including works on philosophy, psychology and motivation. As a result of the investigation, the author concludes that theoretical frameworks, serving as depictions of various facets in the establishment of human motivation, delineate innate and acquired forms of motivation. Furthermore, a classification of motives into external and internal categories is posited: external motivation is linked to a societal orientation, whereby the individual predominantly self-defines through social integration and is more contingent on one's own social standing. In contrast, the internal type of motivation, geared towards outcomes, exhibits less dependence on society and significantly diminishes its inclination towards social approval.

At the moment, one of the most common causes of morbidity and mortality is coronary heart disease, which determines the need to develop methods for its diagnosis. Among diagnostic methods, non-invasive methods occupy a special place, in particular, determination of myocardial perfusion. One of the “gold standards” for assessing cardiac muscle perfusion is positron emission tomography combined with computed tomography (PET/CT) with 82Rb-chloride. Recently, attempts have been actively made to introduce the use of artificial intelligence in a variety of areas of medical clinical practice, including the development of medical decision support systems, as well as neural networks for assessing the results of diagnostic studies. In particular, there is information about attempts to use artificial intelligence in assessing myocardial perfusion using PET/CT with 82Rb-chloride. This paper analyzes the possibilities and prospects for using artificial intelligence in assessing the results of PET/CT with 82Rb-chloride. The use of well-trained neural networks and machine learning algorithms can significantly increase the accuracy of diagnosing coronary heart disease by improving the quality of images, analyzing the data obtained, or calculating characteristics and indicators, the quantitative interpretation of which may be difficult for a doctor. Neural networks are able to take into account in the prognosis both clinical and anamnestic data and additional parameters determined from research data, which the doctor may not pay attention to, which determines the relevance and prospects for the use of artificial intelligence in relation to the interpretation of 82Rb-PET/CT results.

Published: December 2023

The orientation of the teacher's personality which determines his/her moral appearance and behavior is the most important basis for understanding the true motives of his/her activity, since its positive pole is a necessary condition for professional development and effectiveness. The article presents the results of an empirical study of the peculiarities of the orientation of teachers of modern secondary schools. 215 teachers of two educational institutions of St. Petersburg took part in the study using the method of personality orientation diagnostics by of V. Smekal and M. Kucer. The results obtained indicate that almost half (48%) of the teachers of the studied sample have a collectivist orientation of personality (for interaction), every third (34%) has a business orientation (for a task), only 18% are focused on themselves (motives of personal well-being). Despite the decreasing tendency of the intensity of teachers' focus on interaction and the increasing number of teachers with a focus on the task as the length of their experience increases, no significant changes in pedagogical orientation at different stages of professionalization were revealed. This makes it possible to characterize the orientation of the personality of teachers of a modern school as a stable construct reflecting the specifics of the activity performed. The results obtained can be useful for the development of educational and correctional-developmental programs for the professional development of teachers, as well as for monitoring the effectiveness of the organization of their work in an educational institution.application into the educational process.
TO THE PROBLEM OF THE INFLUENCE OF DIGITAL MEANS ON THE PSYCHE OF A STUDYING CHILD
Authors: L.V. Lezhnina , E.S. Rogacheva
Published: December 2023

In the era of digital transformation of society and education, the mental development of a child goes differently than before. The purpose of the article is to briefly analyse the state of study of the problem of the influence of digital media on the cognitive development of pre-school and primary school age students. The analysis of foreign and domestic studies revealed the insufficiency, fragmentation and inconsistency of available data on the peculiarities of the cognitive sphere of students using digital media. Noting the impossibility of cancelling the sociocultural evolution of the psyche in the new digital environment, the prospect of systemic research into the child's mental development in the conditions of mixed reality on the basis of the working concept of digital socialisation is emphasised. The analysis of studies of the possible positive and negative effects of school education under conditions of digitalisation has shown the increasing cognitive inefficiency of this largely spontaneous practice. Since the digit itself is not capable of transforming information into knowledge and action, the transition to a properly organised digital education system requires the substantiation of the theory of effective digital learning and the development of digital educational products that offer new ways of organising students' attention, memory, thinking and communication, adequate to their age and psychological characteristics.

The investigation was conducted on the livelihood status of fishers of Chikadubi beel in Dingaputa haor, Netrokona district of Bangladesh for a period of 6 months from August 2020 to December 2020. A total 50 fishers were randomly selected and data were collected from them through direct interview. Focus group discussions were carried out by a previously made checklist. The results showed that the annual income of fishermen varied from BDT 30000 (270.79 USD) to BDT 70000 (631.85 USD). Maximum (58%) fishers were low-income levels from BDT 30000 (270.79 USD) to BDT 40000 (361.05 USD) and trying to shift their professions to other subsidiary professions. Among them 66% of the respondents indicated that this sanctuary is very effective in improving socio-economic status of the fishers. Relatively middle age group (31 to 40 years) dominated in all study areas. Muslim fishermen are the most dominant in the study area. 68% of the fishers live with nuclear families. The highest percentage (62%) fishers can sign only due to economic crisis and lack of awareness about education, (24%) having Primary level education, (14%) have no education as the children dropped out from school before completing their primary education. Housing and sanitation conditions of the fishermen were not well developed. Based on various livelihood parameters, fishermen are leading very poor state of lives. Sanctuary establishment and Community based aquatic resource management strategies may be undertaken with a view to enhance fish production to improve the livelihood condition of the fishers dwelling in the Chikadubi beel area of Dingaputa haor in Bangladesh.

Oyster mushroom cultivation, though cost-effective, faces constraints due to seasonality and substrate availability. An experimental study was conducted in the resource-constrained Darchula district of Nepal from February to May 2022. The aim was to identify and recommend economically sustainable alternatives to rice straw for oyster mushroom production using local substrates in regions with limited resources. Six treatments; rice straw (T1), banana leaves and pseudostem (T2), maize cob (T3), sawdust (T4), grass (Eulaliopsis sp.) (T5), and spent mushroom substrates (T6); were employed in a completely randomized design with four replications. Statistical analysis of growth and yield parameters revealed significant results (P values ranging from P>0.001 to P>0.05) across all parameters. The maize cob treatment exhibited a shorter spawn run period (20.50 days) and the earliest pinhead formation (25 days). The highest total yield (3.14 kg) across three flushes was obtained from paddy straw, followed by T2 and T5, yielding 2.05 kg and 1.43 kg, respectively. Sawdust, despite its larger stalk (1.23 cm) and pileus diameter (7.72 cm), had the lowest production (0.63 kg). Maximum biological efficiency was recorded for T1 (139.63%), followed by T2, T5, and T3, respectively. Economically, T1 resulted in the highest gross margin per 10 kg of substrate (NRs.1845.22) and the highest B:C ratio (2.51), followed by T5 and T2. These findings highlight the promise of locally abundant substrates such as banana leaves, pseudo stems, Eulaliopsis, and maize cobs as economically viable alternatives to rice straw in regions with limited straw availability or unsuitable climates for rice cultivation.

An experiment was aimed to discover the overall scenario of physico-chemical parameters along with the qualitative and quantitative analysis of plankton in two different fish culture systems as carp mixed culture and catfish (Pangus) monoculture from September 2021 to February 2022 using conventional techniques. The mean values of transparency and dissolved oxygen (DO) noted at the catfish culture pond were lower than those at the mixed carp culture pond while pH mean values were observed to be higher in the catfish culture pond than in the mixed carp culture pond. A total of 21 genera of phytoplankton were found in both ponds under the groups of euglenophyceae (4), cyanophyceae (4), bacillariophyceae (5) and chlorophyceae (8). Among zooplankton, 13 genera were identified including Rotifera (7), copepoda (2), cladocera (3) and crustacean larvae (1) were recorded in mixed culture ponds whereas in catfish culture ponds, 11 zooplankton genera were recorded including Rotifera (5), copepoda (2), cladocera (3) and crustacean larvae (1). Planktonic abundances were statistically significantly different between the different levels (phytoplankton abundance in CCP, phytoplankton abundance in MCP, zooplankton abundance in CCP, zooplankton abundance in MCP), χ2(3) = 220.46, p < 0.001. Mixed culture pond cyanophyceae, bacillariophyceae, and euglenophyceae are positively associated with water temperature and pH but negatively correlated with DO. Rotifera is negatively associated with catfish culture pond water temperature, whereas chlorophyceae and cyanophyceae are favorably. Catfish monoculture ponds had higher phytoplankton abundance, so phytoplankton grazing fish species could be included with pangus culture to maintain a better water quality.

The present research work was undertaken to study the fate of cleft grafting of five potential monkey jack genotypes during 2020-2021 at the Germplasm Center, Patuakhali Science and Technology University, Bangladesh. Scions from five in situ conserved promising mother plants named as Dumki-Al-S1, Dumki-Al-S2, Dumki-Al-S3, Dumki-Al-S4 and Kalapara-Al-S5 were cleft grafted on seedling rootstock (Dumki-Al-R1) of single genotype. A pot experiment was set in two-factor (Scions and Days after grafting) RCBD with 10 replications. The time required to break bud varied significantly among the treatments and ranged from 14 to 20 days. Dumki-Al-S1 required the maximum time to bud break (20 days) followed by Dumki-Al-S3 (18 days). Dumki-Al-S2 took minimum time (14 days) for bud breaking. The maximum increased length of rootstock found in Dumki-Al-S2 which were 55.00, 55.70, 56.44 and 65.30 cm at 21, 42, 63 and 84 days after grafting (DAG), respectively, followed by Kalapara-Al-S5 (61.80, 54.80, 55.30, and 57.12 cm at 21, 42, 63 and 84 DAG, respectively). Kalapara-Al-S5 showed maximum diameter of rootstock (1.44, 1.70, 1.80 and 1.94 cm at 21, 42, 63 and 84 DAG, respectively) followed by Dumki-Al-S4 (1.08, 1.24, 1.34 and 1.42 cm at 21, 42, 63 and 84 DAG, respectively). The length and diameter of scion of Dumki-Al-S4 and Kalapara-Al-S5 were higher and statistically identical at 84 DAG. The maximum graft height was recorded in Kalapara-Al-S5 (70.60, 73.40, 76.00 and 77.10 cm at 21, 42, 63 and 84 DAG, which was statistically similar with Dumki-Al-S2. Kalapara-Al-S5, Dumki-Al-S3 and Dumki-Al-S4 showed maximum number of leaves per graft at 84 DAG. The maximum graft success of 40% was observed in both Dumki-Al-S1 and Dumki-Al-S3 at 84 DAG, whereas, other treatments had less than 20% graft success. Kalapara-Al-S5 and Dumki-Al-S2 showed significantly higher and identical number of sprouted shoots at 84 DAG. Dumki-Al-S1 showed the maximum lengths and diameters of shoot at 84 DAG. The overall performance of the stionic combinations indicated that Dumki-Al-S1 and Dumki-Al-S3 were found promising for further grafting trials with seedling rootstocks.
Socioeconomic status of the people and their attitude toward conservation in Parsa National Park, Nepal

Published: December 2023

This study aims to investigate the socioeconomic status of communities living in proximity to a park and their attitudes towards conservation. The questionnaires used in this study were carefully designed to achieve the desired research objectives. The majority of people living adjacent to the park depend on agriculture and livestock farming for their livelihood. People also benefit from the forest's resources in many aspects. People’s perceptions of wildlife conservation vary widely and are influenced by various factors such as economic status, cultural background, education status, awareness level, and personal experiences. Respondents with higher education status have been found to exhibit positive attitudes towards conservation. Results have shown that 70% of respondents who live near the park claim that coexistence with wildlife is becoming increasingly problematic. While the respondents are pleased with the practical conservation strategies that have contributed to the rise in wildlife populations, they are concerned about the increasing conflicts with wildlife. Crop raiding is a serious problem in several villages located near dense forests. Livestock depredation is another major issue that has been observed in the same area. Wildlife has been known to attack and kill livestock, causing a significant loss of income for the farmers in these villages. Many people feel that the lack of effective compensation mechanisms has led to a sense of antagonism towards both authorities and conservation efforts as a whole. The importance of effective compensation mechanisms in conservation efforts cannot be overstated. Some of the respondents have noted that the development of ecotourism has the potential to mitigate human-wildlife conflict. Ecotourism provides jobs, income, and other economic opportunities that help improve their socioeconomic status and, in turn, promote conservation.
A Study on the Long-Term Performance of Mergers in the Korean Stock Market
Authors: Park Kyung Suh , Jung Chan Shik
Published: December 2023

This study analyzes the merger-related hypotheses which are managerial overconfidence hypothesis, controlling shareholder interest hypothesis, synergy hypothesis, financial constraint hypothesis, and momentum hypothesis through long-term performance analysis of acquiring firms. As a result of empirical analysis, first, the three-year event-time buy-andhold excess return (BHAR) was about -10% for both the average and median values which is statistically significant. Second, through both calendar-time portfolio excess return and BHAR, we find that the stronger the management's overconfidence is, the lower the longterm performance is. On the other hand, in the case of mergers by horizontal combinations, there was a positive synergy effect. This means that the management overconfidence hypothesis, the financial constraint hypothesis, the momentum hypothesis of merger performance, and the synergy hypothesis are established. Despite the poor long-term performance of mergers between domestic companies, this study provides implications that the merger may be mainly due to unreasonable overconfidence of managers and short-term perspectives of management.
Do Managers Always Make Optimal Investment Decisions: Relationship between Managerial Optimism Measured by BERT and Investment Decision-making
Authors: Byun Jinho , Choi Hae Rin , Lee Yoon Jung
Published: December 2023

This paper aims to investigate the effect of managerial optimism on corporate investment and performance. BERT’s methodology, a machine learning method developed by Google, was used to measure managerial optimism for companies listed on KSE (Korea Stock Exchange) and KOSDAQ from 2009 to 2019. Optimism, when there are capital constraints of companies, is defined as overconfidence, and unlike previous studies, the meaning of managerial optimism and overconfidence is distinguished. The empirical analysis revealed the following: higher the manager’s optimism, higher the cash flow, smaller the size of the firm, larger the debt ratio and lastly, higher the growth potential, higher the investment. Furthermore, in analyzing the relationship between performance and investment, higher optimism and investment was associated with higher corporate performance. Finally, when a company is in a capital constraint state, it was found that managerial optimism negatively affected corporate performance. These findings are consistent with previous studies that showed that more optimistic managers have higher investment and that excessive optimism is not good for corporate value.
