Authors: HLUSHKO Alina , PYRIH Yana ,   National University Yuri Kondratyuk Poltava Polytechnic
Published: April 2023

The article is devoted to the issues of strengthening the financial and economic security of critical infrastructure enterprises of Ukraine under martial law. It is proved that the optimality of the volumes of receivables and payables, their balance, and timeliness of repayment are the basis for ensuring liquidity, solvency, financial independence, and safe functioning of the business entity as a whole. The article analyzes the dynamics, structure, ratio and indicators of turnover of accounts receivable and accounts payable of the critical infrastructure object of JSC “POLTAVAOBLENERGO”. The influence of accounts receivable on the liquidity of the enterprise, its profitability and financial stability is determined. The influence of accounts payable on the financial independence of an enterprise and its solvency is substantiated. The indirect impact of accounts payable on the profitability of an enterprise is proved. It is established that the uncertainty and variability of the business environment, especially under martial law, complicates the process of making management decisions. The level of their validity and effectiveness depends on the ability of management to foresee possible scenarios. Therefore, forecasting is rightly recognized as an integral part of determining the directions of debt optimization. On the basis of forecasting, the risk of debt growth of the researched enterprise is identified and directions for optimizing the amount of receivables and payables are proposed, which will not only improve financial stability but also strengthen the financial and economic security of the enterprise as a whole. The priority measures to optimize the accounts payable of JSC “POLTAVAOBLENERGO” are as follows: introduction of a system of control over accounts receivable and accounts payable at the enterprise; introduction of control over the quality of services provided to consumers; monitoring of settlements with creditors for deferred or overdue debts and identifying reasons for non-compliance with the terms of the contract; obtaining state support under martial law.

Published: April 2023

Background: Primary myelofibrosis is characterized by clonal expansion of hematopoietic stem cell with a non-reactive clonal proliferation of fibroblasts and bone marrow fibrosis, which occurs at an extramedullary hematopoiesis. The clinical features of Primary myelofibrosis include anemia, marked splenomegaly and constitutional symptoms. Ineffective erythropoiesis and extra-medullary hematopoiesis are the main causes of anemia and organomegaly, respectively Objectives : the aim of this study was to evaluate the clinical features, diagnostic tools and the treatment outcome of patients with primary myelofibrosis.Patients and methods: this is a prospective study conducted at the national center of hematology in Baghdad during the period between October 2009 and October 2013. It includes 30 adult patients diagnosed with primary myelofibrosis. Diagnosis was based primarily on bone marrow aspirate and biopsy. The patients were followed up and assessed monthly with complete blood picture and liver function test and renal function test with serum lactate dehydrogenase level.Results: thirty patients were included in this study. There were 16 male and 14 female, the median age was 58 year with range (26-75) years. The most frequent presentation was in the group older than 60 years. Twenty four (80 %) patients had symptoms at diagnosis. The most frequent presentation were the fatigue, left upper quadrant swelling, night sweats, weight loss and fever. The main clinical features were huge splenomegaly which is found in 29 (97%) of patients, while the main finding in blood count at presentation were anemia followed by leukocytosis with leukoerythroblastic blood picture in 22 (73 %) of cases. The level of LDH was high in about 23 (77 %). The bone marrow biopsy showed fibrosis stage 2 in 24 (80 %).Patients who died were in the highest risk groups. The median survival was approximately 28 months.Conclusion: Primary myelofibrosis is part of myeloproliferative neoplasia; it usually runs chronic course. Till now none of the therapeutic modalities approved for treatment of primary myelofibrosis proved to be superior to others, yet the 5 year survival of this disease considered good.

Published: April 2023

BACKGROUND: Natural disasters such as earthquakes have imposed particular problems on small and medium-sized enterprises (SMEs), including on their journey to recovery. Business recovery is a term that has numerous theoretical and practical applications and is frequently regarded as the most elusive stage of a disaster cycle. Hence, it necessitates an exploration. OBJECTIVE: This study examines the determinants of business recovery in the aftermath of a disaster. A framework synthesized from the literature review and hypotheses developed demonstrate factors that drive business recovery. METHODS: This study used an explanatory approach that laid quantitative foundations. The study also tested relevant hypotheses with a statistical approach using the PLS-SEM technique. An off-line survey was conducted using data collected from 272 SMEs in tourism affected by the 2018 Lombok earthquake in Indonesia. The data were analyzed with SmartPLS to test the effects of knowledge management, mitigation strategy, business adaptability, business recovery, and government support. RESULTS: The results indicate that knowledge management, mitigation strategy and business adaptability are determinants of business recovery. However, government support has no influence in leveraging those three determinants of business recovery. This finding may indicate that SMEs that possess a strong level of knowledge management with the ability to formulate a mitigating strategy as well as adapt to certain changes are more likely to succeed in recovering their businesses. In addition, whether or not government support is viable, independently managed SMEs are more likely to progressively perform and be less dependent on aid from other entities on their road to recovery. CONCLUSIONS: KM and mitigation strategy function as determinants of business adaptability subsequent to SMEs’ recovery. On the basis of the resource-based view (RBV), mitigation strategy and business adaptability are influential resources that can leverage firms’ potential for in the quest of competitive advantage and facing environmental turbulence. Nonetheless, government support remains a challenge in the survival of SMEs to cope with the negative impact caused by disaster. Thus, government should strengthen the awareness towards such issue as well as providing much more holistic support in the future particularly to educate SMEs on the importance of mitigation strategy in prior to a disaster.
Continual learning for topological geo-localisation
Authors: Cabrera-Ponce Aldrich A. , Martin-Ortiz Manuel , Martinez-Carranza Jose
Published: April 2023

Geo-localisation from a single aerial image for Uncrewed Aerial Vehicles (UAVs) is an alternative to other vision-based methods, such as visual Simultaneous Localisation and Mapping (SLAM), seeking robustness under GPS failure. Due to the success of deep learning and the fact that UAVs can carry a low-cost camera, we can train a Convolutional Neural Network (CNN) to predict position from a single aerial image. However, conventional CNN-based methods adapted to this problem require off-board training that involves high computational processing time and where the model can not be used in the same flight mission. In this work, we explore the use of continual learning via latent replay to achieve online training with a CNN model that learns during the flight mission GPS coordinates associated with single aerial images. Thus, the learning process repeats the old data with the new ones using fewer images. Furthermore, inspired by the sub-mapping concept in visual SLAM, we propose a multi-model approach to assess the advantages of using compact models learned continuously with promising results. On average, our method achieved a processing speed of 150 fps with an accuracy of 0.71 to 0.85, demonstrating the effectiveness of our methodology for geo-localisation applications.

A lightweight deep learning model based recommender system by sentiment analysis
Authors: Chiranjeevi Phaneendra , Rajaram A.
Published: April 2023

Recommender systems based on sentiment analysis become challenging due to the presence of enormous data available over the internet. With the lack of proper data cleaning and analysis methods, existing machine learning (ML) techniques fail to generate accurate recommendations. To overcome this issue, this paper proposes a Light Deep Learning (LightDL)-based recommender system that uses Twitter-based reviews. First, the data is collected from Twitter and cleaned by subsequent data cleaning processes. Then, this pre-processed data is fed into the LightDL model, which learns the important features like hashtags, unigrams, multigrams, etc. from each piece of data. Here, we have learned about four groups of features, including semantic features, syntactic features, symbolic features, and tweet-based features. Finally, the data is classified into positive, negative, and neutral categories according to the learned features. On the basis of classified sentiment, the review is generated to the users. Finally, the model is evaluated in terms of accuracy, precision, recall, f-measure, and error rate through extensive experiments in Matlab. The proposed LightDL model outperforms in all performance measures; specifically, it achieves 95% accuracy for the Twitter dataset.

Published: April 2023

Background:

Three therapeutic strategies have radically changed the therapeutic scenario for spinal muscular atrophy (SMA). However, therapeutic response differs between individuals. There is a need to identify biomarkers to further assess therapeutic response and to better understand which variables determine the extent of response.

Methods:

We conducted a study using an optimized digital droplet PCR-based method for the ultra-sensitive detection of SMN transcript in serum EVs from SMA 2 individuals treated with nusinersen over 14 months. In parallel, we investigated levels of serum and CSF neurofilament heavy chain (pNF-H) in the same cohort.

Results:

Expression of flSMN transcript in EVs of SMA 2 individuals prior to nusinersen was lower than in controls (0.40 vs 2.79 copies/ul; p < 0.05) and increased after 14 months of nusinersen (0.40 vs 1.11 copies/ul; p < 0.05). The increase in flSMN with nusinersen was significantly higher in younger individuals ( p < 0.05). Serum pNF-h was higher in non-treated individuals with SMA 2 than in controls (230.72 vs 22.88 pg/ml; p < 0.05) and decreased with nusinersen (45.72 pg/ml at 6 months, 39.02 pg/ml at 14 months). CSF pNF-h in SMA 2 individuals also decreased with nusinersen (248.04 pg/ml prior to treatment, 197.10 pg/dl at 2 months, 104.43 pg/dl at 6 months, 131.03 pg/dl at 14 months).

Conclusions:

We identified an increase of flSMN transcript in serum EVs of SMA 2 individuals treated with nusinersen that was more pronounced in the younger individuals. Our results indicate that flSMN transcript expression in serum EVs is a possible biomarker in SMA to predict or monitor the response to treatment.

Authors: Fathollahy Isa , Baglari Babak , Pirsa Sajad
Published: April 2023

Polycyclic aromatic hydrocarbons (PAHs) are a large group of cyclic aromatic hydrocarbons that have been listed as hazardous substances by the US Environmental Protection Agency and the World Health Organization. Edible oils are one of the important food sources of PAHs, which are created during the processes of drying oil seeds or refining edible oils. The aim of this research was to evaluate PAHs (Naphthalene, Fluorene, Phenanthrene, Anthracene, Fluoranthene, Pyrene, Benzo[a]pyrene, and Benz[a]anthracene) in industrially produced edible oils (sunflower, corn, canola, olive and sesame) and traditional oils (press) (yellow animal oil, olive, sesame and sunflower oil) in Iran, and these samples were randomly prepared, sampled and analyzed from the stores of West Azarbaijan province (Urmia, Iran). PAHs were extracted from oily samples by solid phase microextraction method and analyzed by Gas Chromatography-FID. The highest concentration of PAHs (μg/L) were related to different oils as the follow: naphthalene (4.61 in animal yellow oil), Fluorene (0.75 in canola), Phenanthrene (0.21 in canola), Anthracene (0.01 in animal yellow oil), Fluoranthene (2.53 in canola), pyrene (2.67 in canola), Benz[a]anthracene (0.44 in corn) and Benzo[a]pyrene (0.45 in canola). The concentration of Benzo[a]pyrene was compared with the European Union (EU) limit value (μ>2) using one-sample t-test. In industrial canola oil, with an average concentration of 2.593μg/kg, Benzo[a]pyrene was higher than the European Union standard of 2μg/kg. Some of the studied aromatic hydrocarbons could not be detected in some oils.

BACKGROUND: Several studies have continuously investigated FFRs using binaural beat (BB) stimulations and their related effects. However, only a few studies have investigated the differences in BB stimulation effects according to basic demographic characteristics, such as gender and age. OBJECTIVE: This study aimed to determine the alpha wave activity after a 10-Hz BB stimulation and subsequently identify differences according to gender across all brain areas (frontal, central, parietal, temporal, and occipital areas). METHODS: A total of 23 healthy adults (11 male and 12 female), aged 20–29, participated in the study. For the 10-Hz BB stimulation, pure tone auditory stimuli of 250 and 260 Hz were given to the left and right ear, respectively. Through a power spectrum analysis of the phase-excluding BBs (non-BBs) and phase-including 10-Hz BBs (α-BBs), the alpha power at each brain area was estimated. These values were compared using a mixed-design ANOVA. RESULTS: With the exception of the temporal area, all other brain areas showed a significant increase in alpha power for α-BBs compared to those of non-BBs. However, the difference according to gender was not significant. CONCLUSION: The results indicated the lack of gender effects in alpha wave generation through a 10-Hz BB stimulation.

Published: April 2023

BACKGROUND: Differential protein expression of the oral microbiome is related to human diseases, including cancer. OBJECTIVE: In order to reveal the potential relationship between oral bacterial protein expression in oral squamous cell carcinoma (OSCC), we designed this study. METHODS: We obtained samples of the same patient from cancer lesion and anatomically matched normal site. Then, we used the label free quantitative technique based on liquid chromatography tandem mass spectrometry (LC-MS/MS) to analyze the bacteria in the samples of oral squamous cell carcinoma at the protein level, so as to detect the functional proteins. RESULTS: Protein diversity in the cancer samples was significantly greater than in the normal samples. We identified a substantially higher number of the taxa than those detected in previous studies, demonstrating the presence of a remarkable number of proteins in the groups. In particular, proteins involved in energy production and conversion, proton transport, hydrogen transport and hydrogen ion transmembrane transport, ATP-binding cassette (ABC) transporter, PTS system, and L-serine dehydratase were enriched significantly in the experimental group. Moreover, some proteins associated with Actinomyces and Fusobacterium were highly associated with OSCC and provided a good diagnostic outcome. CONCLUSION: The present study revealed considerable changes in the expression of bacterial proteins in OSCC and enrich our understanding in this point.

BACKGROUND: Ginkgo Folium has a favorable effect on non-alcoholic fatty live disease (NAFLD), but its mechanism remains unclear. OBJECTIVE: The aim of this study is to reveal the underlying mechanism of Ginkgo Folium in the treatment of NAFLD. METHODS: Ingredients of Ginkgo Folium and ingredients-related genes were collected from TCMSP database and SwissTargetPrediction website, respectively. Genecards database was used to obtain NAFLD-related genes. Next, the protein-protein interaction network and key ingredients-genes network were constructed via Cytoscape3.7.0. Based on the Metascape website, gene ontology function analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis were carried out for key genes. Finally, molecular docking was performed to present the interaction between components and genes using AutoDock Vina 1.1.2. RESULTS: Eighteen active ingredients and 10 target genes were screened from Ginkgo Folium. AKT1, TNF, EGFR, PTGS2, MAPK8, PPAγ, APP, ESR1, HIFα and PPAα were considered as potential therapeutic targets. These target genes were mainly enriched in insulin resistance, HIF-1, adipocytokine and AMPK signaling pathways. Molecular docking results suggested that Ginkgo Folium active ingredients including luteolin-4′-glucoside, sesamin, luteolin, chryseriol, isorhamnetin and laricitrin showed strong binding capacities with AKT1. CONCLUSION: The study showed that multi-components in Ginkgo Folium interacted with AKT1 and regulated AKT-AMPK/HIF pathway to alleviate NAFLD. Our findings provided an essential role and basis for new anti-NAFLD drug discovery and further research on Ginkgo Folium.

Published: April 2023

BACKGROUND: There is a need for an improved version of the implantable catheter for malignant ascites in the abdominal cavity. OBJECTIVE: New implantable catheters have been developed that drain ascites from the abdominal cavity to the bladder by applying pressure. Based on pigtail catheters, these newly designed catheters have silicone membranes and apertures. METHODS: Experimental instruments controlled flow rates and water level to observe changes of the activation pressure and its cycle time along flow rates and turns of catheters. Furthermore, various normality tests, difference tests and non-parametric tests were investigated to observe statistical validity. RESULTS: Cycle times were significantly affected by flow rate (3/4 cases of p< 0.05). The effects of flow rate on activation pressure, however, were not significant (1/4 case of p< 0.05). Cycle times were not significantly affected by the number of turns of the catheter (3/8 cases of p< 0.05). In contrast, the effects of the turns on activation pressure were significant (5/8 cases of p< 0.05). CONCLUSION: Overall, there was no significant difference between cycle times for 1.5 turns and 2.0 turns of catheters. In addition, catheters with 1.5 turns have a lower activation pressure than catheters with 2.0 turns. It is possible to customize catheters based on the ascites excretion and urination rates of various terminal patients.

The paper emphasizes the important role of socio-psychological attitudes of the individual in various spheres of life. Socio-psychological attitudes have a huge impact on motivation, professional self-determination, and other aspects of the high schooler. Adolescence is a sensitive period for the development of emotional intelligence. Depending on the extent to which the emotional intelligence of the student is expressed, there can be various manifestations of the socio-psychological attitudes. Materials and methods. The study aims to explore the features of socio-psychological attitudes in high school students with various levels of emotional intelligence. The main method of research is testing. The study also relies on the emotional intelligence questionnaire ”Emin” (D. V. Lyusin), the Methodology for diagnosing socio-psychological attitudes of a person in the motivation-and-need sphere (O. F. Potemkina), and the Scale of optimism and activity (N. Vodopyanova, M. Stein). Students of grades 10-11 took part in the diagnostic tests. Results. The findings have revealed that intrapersonal emotional intelligence is better developed in high school students, whereas some indicators of emotional intelligence show their insufficient level of their development. These are understanding of other people’s emotions, sensitivity to the inner state of another person and, in general, interpersonal emotional intelligence. The integral indicator of emotional intelligence is average for the majority of respondents. Altruism orientation and money orientation predominate in the socio-psychological attitudes of the individual. In our opinion, altruism for high school students is a way to acquire the moral experience of humanity, and their money attitude is connected with the values and attitudes of their family. Discussion and Conclusion. The study has proved that there are specific features of the socio-psychological attitudes of high school students with different levels of emotional intelligence, namely: students with a high level of emotional intelligence focus on the process and altruism, their expression of optimism and activity is also higher than that in the students with low emotional intelligence.

Published: April 2023

When participating in the financial market, few investors can sustainably succeed in the market, most of them often make psychological mistakes that lead to failure. The article applies theories and synthesizes empirical studies to analyze common mistakes of individual traders based on the theory of behavioral finance, including: prospect theory, herding effect, house money effect, sunk costs, and overconfidence. The article uses qualitative methods combined with descriptive statistics on a sample of 120 individual investors who are directly trading on the financial market, using a convenience sampling method. The results show that the disposition effect has the strongest impact on investors' decisions, specifically, 81.3% of investors often close their profit positions too soon while the trend is still continuing. Hesitating when making decisions or trading with weak signal, being influenced by others also have a strong impact on the trader, the rest of the factors have a moderate impact. From those results, the article analyzes that the main cause of psychological deviations is "fear" inside each person. Investors close their profit positions early because of the regret aversion if losing that profit, they hesitate to make decisions because of the fear of making mistakes, affected by the herd effect is due to the isolation aversion. On that basis, the article proposes solutions to help investors control psychological factors to survive and succeed in their trading activities, the solution emphasizes self-discipline, planning, and a constant learning process.

The higher education sector is becoming increasingly competitive as students currently have more opportunities to pursue undergraduate degrees. Universities apply marketing strategies to student recruitment and gain the insights about prospective students more closely, which is similar to the process businesses learn about consumer attitudes and behavior. Therefore, the study on the students' intention of choosing a university is necessary. Despite its importance, few previous studies in Vietnam have explored this issue, especially the analysis of choice factors of students throughout the decision-making journey. To explore in-depth the considerations and factors that influence students in this decision-making journey, qualitative data was collected by interviews with freshmen students. Choice factors are divided into three main dimensions, comprising institution-related factors, student-related factors and information sources. The results provide remarkable findings to help universities understand more about the elements which students are interested in and search for during the decision-making process, the importance of paticular choice factors in each stage to adjust the marketing strategies over the stages.

Sustainable livelihood is not only the livelihood objective but also households’ expectations. Livelihood diversification is aimed at ensuring the farmer's resilience to shocks and improving livelihood sustainability. Research on livelihood diversification in rural areas contributes to the development of agricultural development policies, social security policies for all farm households in Vietnam. The authors applied statistic and regression methods to analyze VARHS’s database which is surveyed 12 provinces in Vietnam over years. This paper is carried out to analyze and evaluate factors affecting the probability of choosing to diversify the livelihoods of Vietnamese farmers by developing a diversification index (SID) and SID’s determinants based on the DFID framework. The results show that the decision to diversify livelihood is influenced by many factors, including age, planted areas, asset value, saving money. Since then, the authors propose some implications for promoting the livelihood diversification of Vietnamese farmers.
The role of FDI in Vietnam's economic development
Authors:   Khanh Hoa University, Vietnam, Trần Thị Trân Châu
Published: April 2023

Since Vietnam joined the World Trade Organization (WTO) in 2007, foreign direct investment (FDI) into Vietnam has increased sharply and has become one of the important sources of capital for the economic development of the country. However, apart from the positive aspects that FDI brought, there were also many negative aspects affecting the economic, political, social, and environmental fields. By analyzing the current situation, role, and limitations of FDI in Vietnam's economic development, the study shows that FDI inflows into Vietnam had positive changes in the period 2010 - 2020. During the research, the analytical data was collected from secondary data from the yearbook of the General Statistics Office and the reports of the Foreign Investment Department - Ministry of Planning and Investment, using the descriptive statistics, synthesis, and analysis to analyze data to describe the effects and qualitative relationship between FDI and economic development in Vietnam. The research results show that in the period 2010-2020, FDI capital continuously increased in total registered capital and realized capital; the proportion of FDI contribution to GDP also increased gradually over the years, however, there was an imbalance between registered capital and realized capital, and the contribution of FDI to GDP was still limited. At the same time, the results also show that the capital of FDI invested in Vietnam and many economic sectors primarily stems from Asian countries while the number of investors in developed countries such as Europe and the Americas is yet inconsiderable, and FDI mainly focuses on processing and manufacturing industries. Based on the research results of the article, a number of solutions are proposed to help Vietnam attract more foreign-invested projects, contributing to promoting Vietnam's economic development in the coming time.

The analysis of literary sources made it possible to state that the surface roughness obtained by the finish anti-friction non-abrasive treatment (FANT) is one of the main quality criteria of the anti-friction coating and largely determines the process of running-in during the initial period of operation. The purpose of the presented research is to establish the main patterns of changes in the roughness of the surface layer treated by FANT. Application of anti-friction coatings was carried out according to the method developed by the authors using the original device on a vertical milling machine. Special disc-shaped samples made of gray cast iron SCH20 were used as the tested samples. L63 brass was used as the material of the anti-friction coating. Among the technological factors that changed with the selected FANT scheme, the following were selected: the pressure force of the anti-friction bar and the number of rubbing passes. The roughness of the surface was estimated by the average arithmetic deviation of the Rа profile. The average value obtained as a result of three measurements was taken as the value of the roughness parameter Rа. The obtained values made it possible to establish the main patterns of changes in the roughness parameter depending on the technological parameters of FANT. It is shown that with an increase in the initial surface roughness parameter Rа, the value of the change in the average arithmetic deviation of the profile Ra also increases. High initial values of the arithmetic average deviation of the Ra profile do not allow obtaining a continuous, and therefore high-quality anti-friction coating of FANT. Obtaining a high-quality anti-friction coating with the selected FANT scheme became possible with the following processing modes: pressing force of the anti-friction bar P = 164.6 N; the number of rubbing cycles is N = 6. The results of the studies performed on the application of FANT anti-friction coatings make it possible to predict and control such an important geometric parameter of the surface layer as roughness, which largely determines the quality of the treated surface.

Just war thinking features the history of warfare from the beginning up to the 20th century. Just war thinking, however, did not have one unique frame, but it appeared in many forms. The theory of judgement of God, the mission-related theory, the law enforcement theory, the revolutionary, and finally, the regular war theory were the important forms of historical just war thinking. This article presents these theories and classifies them with the help of the main concepts of Saint Thomas Aquinas and the principal concepts of justice.

The purpose of this article is to present the basis for building trust within the European Union, through which the authors illustrate the importance of the protection of personal data as a fundamental requirement in both the EU and its Member States’ legal environments. In addition, the authors have examined the Chinese Social Credit System, which by its design and operation is not primarily focused on building trust and is therefore not the most appropriate solution for building trust. The authors conducted a SWOT analysis comparing the EU and Chinese principles to achieve their objectives. They also conducted interviews with people who have personal experience with the Chinese credit point system. Based on the results obtained, they sought to justify their basic hypothesis that this type of credit system could not be applied within the EU.

The article is devoted to the relationship and consequences of migration and human trafficking in conditions of armed conflict. It was noted that the full-scale invasion of the Russian Federation on the territory of Ukraine became an impetus for rethinking human trafficking: women and children who are forced to leave Ukraine due to Russia’s military aggression and head for neighboring countries face the risks of human trafficking. Men who remain inside the country can also become prey for traffickers. It is outlined that before the events of February of the current year, the study and formation of migration processes, as well as the reasons for the migration of the Ukrainian population, were aimed at the implementation of preventive measures to overcome the consequences and maximize the benefit of the results caused by such processes. The research determined that such an aspect as the forced and unauthorized transfer of Ukrainian citizens to the territory of the Russian Federation and the occupied territories remains overlooked in statistical information, since there is no exact number of deportees. The figures given in the mass media and in the speeches of representatives of state authorities are approximate, and the number of such persons is much larger; in terms of the number of recorded criminal offenses, there are much more of them, because human trafficking has a high latency, since victims of human trafficking do not want to report it to law enforcement agencies. It was established that as of November, 2, the analysis of the “Legislation of Ukraine” database allows us to note that it contains 66 normative legal acts related to combating human trafficking, however, since the beginning of the full-scale invasion of the Russian Federation on the territory of Ukraine, not a single resolution, decree, orders, etc., were not amended or supplemented. A conclusion was made about the need to make changes to the current legal acts, as well as to pay attention to such a category as internally displaced persons by the national coordinator in the field of combating human trafficking – the Ministry of Social Policy of Ukraine, as well as to conduct explanatory work with citizens of Ukraine , who are traveling abroad due to armed conflict, at the checkpoints, providing them with detailed information about the National Hotline for Combating Human Trafficking, Preventing and Countering Genderbased Violence and the Emergency Helpline in all EU countries. Key words: migration; human trafficking; armed conflict; internally displaced person; causes (factors) of human trafficking.
