Results of Using Optical Simulators “Zenitsa” for the Treatment of Myopia in School Settings

Introduction. Acquired myopia (AM) is currently a growing medical and social concern as it is associated with a steadily increasing number of myopic students, early onset of its development, rapid progression and further complications. The main cause of AM is considered to be the depletion of the visual system adaptive capabilities because of too much near vision. According to the adaptation theory, it is necessary to create a high stable level of adaptive reserves of the visual system in order to normalize the process of refractive development in AM. Treatment methods of AM aimed to increase the efficacy and adaptive capabilities of eyes include optical reflex exercises. These exercises in particular using Zenitsa optical simulators compare favorably with other methods due to their physiological and pathogenetic orientation of the action mechanisms.Purpose. To study the features of using optical simulators “Zenitsa” for the treatment of acquired myopia in school settings and the dynamics of myopic process course.Material and methods. The group of 25 elementary students (50 eyes, the average age was 9.05 ± 0.72 years) with mild myopia was identified by random sampling. The study was conducted from November to December 2021. 95% of children had asthenopic complaints and 85% of students had a hereditary predisposition to it. The examination included questionnaire, visiometry, skiascopy, ophthalmoscopy, a measure of subjective refraction and relative accommodation reserves, a study of binocular stability of visual perception to hypermetropic retinal defocus. The course of treatment included 10 sessions that were carried out in school settings. We used seven simulators “Zenitsa” each of different optical strength.Results. After the treatment with the use of optical simulators, visual acuity improved on average from 0.58 to 0.67 (P < 0.01). Subjective refraction decreased from (-)1.48 ± 1.1 to 1.28 ± 1.08 D, by an average of 0.20 D (P < 0.01). Relative accommodation reserves increased from 2.33 ± 0.84 to 3.17 ± 1.07 D, by an average of 0.84 D (P < 0.01). Binocular stability of visual perception increased by an average of 1.5 D that is 15% of the initial level. The value of visual resolution increased by an average of 7.2%.Conclusion. The use of optical simulator “Zenitsa” sets significantly improves the performance of accommodation and vergence and increases the level of visual system adaptive capabilities in whole.

The mechanism of suppression of the synthesis of toxic gases and their indirect influence on the vital signs of the animal organism with adaptive growing technologies

Relevance. Many scientists reasonably believe that disturbances in microclimatic parameters are the basis for reduced adaptation of the animal organism to environmental conditions, to aggressive stress factors affecting the immune system of animals. This leads to a violation of the barrier function of the lungs, the rapid multiplication of microflora in the mucous membrane of the upper and lower respiratory tract, the development of exudative processes and a bright leukocyte reaction.Methods. To conduct the experiment in the winter stall period of 2021–2022, calves of the Holstein breed aged 15.0± 5.0 days were selected, from which two groups were formed according to the principle of pairs of analogues of 15 heads each.Results. The authors found that the use of a «Biological inactivator of toxic gases in the litter» for animals makes it possible to achieve a significant reduction in the amount of ammonia in the air inhaled by calves of the over-lining layer. At the same time, the respiratory function of the animal organism is activated (normalization of the body's homeostasis, improvement of erythropoiesis, reduction of erythrocyte sedimentation rate, increase in the level of alkaline blood reserve, etc.).

8Spheres conformal microspheres as embolic agents for symptomatic uterine leiomyoma therapy in uterine artery embolization (UAE): A prospective clinical trial.

To evaluate the treatment efficacy of uterine artery embolization (UAE) using 8Spheres conformal microspheres for symptomatic uterine leiomyoma. In this prospective observational study, 15 patients were enrolled and underwent UAE by 2 experienced interventionalists from September 1, 2018, to September 1, 2019. All patients underwent menstrual bleeding scores, the symptom severity domain of the Uterine Fibroid Symptom and Quality of Life questionnaire scores (with lower scores indicating mild symptoms), pelvic contrast-enhanced magnetic resonance imaging, ovarian reserve tests (estradiol, prolactin, testosterone, follicle-stimulating, luteinizing, and progesterone), and other appropriate preoperative examinations within 1 week before UAE. During follow-up, menstrual bleeding scores and the symptom severity domain of the Uterine Fibroid Symptom and Quality of Life questionnaire scores were recorded at 1, 3, 6, and 12 months after UAE to assess the efficacy of symptomatic uterine leiomyoma. Pelvic contrast-enhanced magnetic resonance imaging was performed 6 months after the interventional therapy. Biomarkers of ovarian reserve function were reviewed at 6 and 12 months after treatment. All 15 patients successfully underwent UAE, without severe adverse effects. Six patients experienced abdominal pain, nausea, or vomiting, all of which improved significantly after symptomatic treatment. The menstrual bleeding scores declined from baseline (350.2 ± 61.9 mL) to (131.8 ± 42.7 mL), (140.3 ± 42.4 mL), (68.0 ± 22.8 mL), and (64.43 ± 17.0 mL) at 1, 3, 6, and 12 months, respectively. The symptom severity domain scores at 1, 3, 6, and 12 months postoperatively were significantly lower and statistically significant compared to the preoperative scores. The uterus and dominant leiomyoma volumes decreased from baseline (340.0 ± 35.8 cm3), (100.6 ± 24.3 cm3) to (266.6 ± 30.9 cm3), (56.1 ± 17.3 cm3) at 6 months after UAE, respectively. Moreover, the ratio of leiomyoma volumes and uterus decreased from (27.4 ± 4.5%) to (18.7 ± 3.9%). At the same time, there was no significant effect on changes in the biomarkers of ovarian reserve levels. Only the changes in testosterone levels before and after UAE were statistically significant (P < .05). 8Spheres conformal microspheres are ideal embolic agents for UAE therapy. This study showed that 8Spheres conformal microsphere embolization for symptomatic uterine leiomyoma could effectively relieve heavy menstrual bleeding, improve the symptom severity of patients, reduce the volume of leiomyoma, and have no significant effect on ovarian reserve function.

Intelligent control System wide-reach Sprinklers circular action

The relevance of the introduction of intelligent control systems for agricultural machinery in the modern world is increasing every year due to the development of more and more global projects in the field of automation and robotics. The purpose of the research was to develop algorithmic software for an intelligent control system for wide-reach sprinkler machines for autonomous operation in the implementation of environmentally safe, high-quality irrigation. The article considers the possibility of matching the irrigation norm issued by the machine to the level of moisture reserves of the field for circular-acting machines, reducing the environmental load on the soil and preserving fertility. The use of an intelligent control system with the proposed algorithm of operation will improve the quality and environmental safety of irrigation, as well as ensure resource savings, in particular irrigation water savings.

Change in Decision-Making Analysis and Preferences in Old Age.

To test the hypotheses that decision making ability declines in old age and that a higher level of cognitive reserve is associated with a reduced rate of decline. As part of an ongoing cohort study, 982 older adults without dementia at study enrollment completed measures of purpose in life and cognitive activity which were used as markers of cognitive reserve. At annual intervals thereafter, they completed 6 tests of decision making. In a factor analysis of baseline decision making scores, 3 measures (financial/health literacy, financial/health decision making, scam susceptibility) loaded on an "analytic" factor and 3 (temporal discounting small stakes, temporal discounting large stakes, risk aversion) loaded on a "preferences" (for temporal discounting and avoiding risk) factor. During a mean of 4.7 years of follow-up (standard deviation = 2.9), analytic factor scores decreased (mean = 0.042-unit per year, standard error [SE] = 0.006, p < .001) and preferences factor scores increased (mean = 0.021-unit per year, SE = 0.006, p < .001), with a correlation of 0.13 (p < .001) between rates of change. Evidence of an association between cognitive reserve and decision making was mixed with purpose in life related to change in analytic decision making, whereas past (but not current) cognitive activity was related to change in decision making preferences. Decision making analysis and preferences change over time in late life. Change over time in decision making components is relatively independent and differentially related to age and cognitive reserve.

Cash holding management for self-financing phase-able and non-phase-able project portfolio selection and scheduling problems

This article presents a novel mathematical model for managing the level of cash reserves for the self-financing phase-able as well as non-phase-able project portfolio selection and scheduling problems. Practically, the executive managers of project-oriented organizations tend to keep cash within their organization to increase their decision-making power. Although this allows managers and investors to invest in future economic projects, it imposes opportunity costs on owners and investors, in which case maintaining cash reserves can turn out to be a major challenge between owners and executive managers. This issue becomes more acute when the project-based organization operates self-financing. Because the financing is limited to the revenues of the finished projects, money withdrawn from the project account without proper management exacerbates financial constraints. Consequently, managers will bypass some future valuable investment opportunities. In this article, from the point of view of cash holding, the expectations of managers and investors in a self-financing phase-able and non-phase-able project-based organization will be met simultaneously. The proposed model is a nonlinear integer program. After linearization, an example is provided to illustrate the applicability and performance of the proposed model.

How does Chinese-style fiscal decentralization affect green technology innovation?

Green technology innovation is crucial to green transformation. Accordingly, the influence of Chinese-style fiscal decentralization on green technology innovation is contingent on whether effective green competition can occur among hierarchical governments. Against this backdrop, the Spatial Durbin Model is used to empirically estimate the impact of Chinese-style fiscal decentralization on green technology innovation, which utilized the panel data of 30 provinces in China from 2010 to 2020. The findings revealed a significant spatial agglomeration effect for green technology innovation in various regions. Besides, fiscal decentralization is evidenced to not only have a positive spatial spillover effect on green technology innovation but also promote green technology innovation at the local level and in surrounding areas, indicating that local governments have formed green preferences and facilitated green innovation technology competition. Moreover, further analysis of induced resource allocation reveals that financial support and environmental regulation have adverse inhibitory and positive promotion effects on green technology innovation, respectively. Furthermore, foreign direct investment, research and development intensity, knowledge reserve level, and industrial structure have varying spatial spillover effects on the level of green technology innovation. In light of these findings, this study recommended that the Chinese government further improves its fiscal decentralization, implements green performance evaluation of local governments, and enhances the coordinated development of various innovation incentives.

Evaluation of the Carry-Over Effect of the “Crop-Forcing” Technique and Water Deficit in Grapevine ‘Tempranillo’

“Crop-forcing” is an effective technique to delay grape maturation to a period of lower temperatures, and in this way, improve grape quality. Because of the aggressiveness of this technique (removal of leaves and fruit to reinitiate a second vegetative cycle), it may affect the level of reserves and could provoke progressive vine exhaustion. The aim of the present work is to evaluate the short- and medium-term evolution of carbohydrate reserves in different plant organs and the effect of “crop-forcing” under different irrigation regimes on seasonal biomass production and its distribution. The study was carried out over a four years period (2017–2020), applying “crop-forcing” in three consecutive years (2017–2019) to the same vines on two different dates and using two irrigation strategies. The application of “crop-forcing” did not decrease root reserve levels in either the year of application or the following year, but did modify starch and soluble sugar levels in shoots and leaves in some moments of the vegetative cycle during the years of “crop-forcing” application. Total biomass production in terms of grams per vine was lower in the “crop-forcing” treatments and continued to be so when “crop-forcing” was no longer applied. The percentage of biomass in vegetative organs increased at the expense of productive organs.

Determinante deviznih rezervi i optimalni nivo deviznih rezervi u Bosni i Hercegovini

The research answered the question of what affects BH foreign exchange reserves and what is the lower limit of the optimal level of foreign exchange reserves of the Central Bank of Bosnia and Herzegovina (CBBH). We defined excess foreign exchange reserves as the difference between the balance of foreign exchange reserves and the lower limit of the optimal level of foreign exchange reserves. In most of the analyzed period, foreign exchange reserves are significantly above the lower limit of the optimal foreign exchange reserves. In 2022, the banking sector had the largest excess of foreign exchange reserves in the scenario of a floating exchange rate, without considering the degree of euroization. The excess is the lowest in the fixed exchange rate regime, in which, through the money supply, we allowed a high impact of euroization on optimal foreign exchange reserves. Even under this most conservative scenario, the excess foreign exchange reserves amount to 1.9 billion KM or about 4% of nominal GDP in 2022. Changes in BH monetary regime, enabling the CBBH to lend to residents and a possible transition to a floating exchange rate, are possible while maintaining a satisfactory level of foreign currency liquidity of the CBBH.

Chance-constrained Calculation of the Reserve Service Provided by EV Charging Station Clusters in Energy Communities

The concept of energy community is currently under investigation as it is considered central into the energy transition process. One of the main aspects of the successful implementation of community lays in the energy management system that coordinates exchanges among prosumers. This paper deals with the optimal energy management of a local energy community of dc microgrids with electric vehicle charging stations, considering local reserve provided by storage units and vehicle batteries. A two-stage optimal procedure is proposed to assess the optimal scheduling of resources for each community participant. Additionally, the optimal up and down reserve levels able to cover random fluctuations in photovoltaic generation within each EV-based microgrid are determined by a set of specific chance constraints.

Analysing the development of renewable energy sources in European countries

This article investigates different types of electricity generation in European countries. The authors examined the trends of renewable electricity generation in Northern, Southern, Western and Eastern Europe. A cluster analysis was performed based on the factors that may predetermine the possibility of using different types of electricity generation: the level of economic development, the amount of air pollutant emissions and the level of energy reserves. Multiple discriminant analysis was used to test the hypothesis that each cluster is characterised by a specific direction. The dependent variable was the country's membership in the clusters, and the independent variables were the types of electricity generation used by the countries: thermal power generation (oil refinery products, gas, coal), nuclear power, hydropower, wind power, solar power, and bioenergy.

Justification of technological solutions for irrigation with electrified circular sprinkler machines

Improving the quality of irrigation can be achieved by changing the irrigation rate in accordance with the level of moisture reserves of the field areas at the time of watering, eliminating over-watering and water erosion of soils. The purpose of the presented research was to improve the technological process of irrigation with wide-reach circular sprinkler machines, which ensures the reduction of unproductive water losses, improving the quality of irrigation. The article discusses theoretical studies of irrigation technology with circular sprinkler machines, optimized irrigation modes. Based on the conducted experimental studies, a comparative assessment of the work of sprinklers according to the standard and proposed technology, taking into account the adjustment of irrigation norms, is presented. Comparison of standard and proposed irrigation technologies with sprinkler machines showed that irrigation using the proposed technology allows saving irrigation water up to 10%.

Effects of the beta-stimulating training in recovery of adaptive reserves in athletes of different sports

To identify effects of the beta-stimulating training in recovery of adaptive reserves in athletes of different sports. The study included young male athletes aged 18-22 years (n=1020), distributed according to the type of sports: group 1 - cyclic sports (n=387); group 2 - speed-strength sports (n=255); group 3 - single combat (n=31); group 4 - team sports (n=173); group 5 - complex-coordination sports (n=174). The main objective of the beta-stimulating training was to select a strategy to raise the beta rhythm level while muscles were relaxed. For each group, we identified training efficiency periods according to the lowest value of the attention index (θ/β, c.u.), then we examined distribution of brain rhythms (α, %; β, %; θ, %) according to EEG. The level of adaptive reserves was identified according to the heart rate variability (HRV) spectral analysis («VNS-Spektr», Neurosoft, Ivanovo). We identified following periods of the beta-stimulating training efficiency according to the attention index (θ/β, c.u.): group 1 - 10th session (game variant); group 2 - 5th session (graphic and game variants); group 3 - 1st and 10th sessions (game variant), 5th session (graphic variant); group 4 (game variant) - 1st, 5th and 10th sessions; group 5 (game variant) - 5th and 10th sessions. The efficiency periods in the observed groups were accompanied by the following distribution of rhythms in the EEG structure: β-rhythm - 45-60%; θ-rhythm - 20-35%, α-rhythm - 19-25%. During these periods, wave structure of the heart rhythm also changed: the activity of VLF waves increased (%); the proportion of HF waves decreased in the range of 23.3-31.59% in the groups 1, 2 and 3; the share of HF waves increased in the range of 32.3-39.8% in the group 4 at the 1st session and in the group 5 at the 10th session. The values of total power (TP, ms2) reduce at the 10th session in the groups 1, 3 and 4 and at the 5th session in the group 5. The vagosympathetic balance coefficient (LF/HF, c.u.) in the studied groups corresponds to the range of normal values; the values increased in the group 2 at the 5th session, in the groups 3 and 4 - at the 5th and 10th sessions, in the 5th group - at the 5th session. The index decreased in the groups 3 and 4 at the 1st session. The index was stable in the groups 1 and 5 at the 10th session of the training. Periods of the beta-stimulating training efficiency associated with the improvement of attention according to the lowest values of θ/β (c.u.) are accompanied by changes in the modulation of the structure of brain rhythms and the wave structure of heart rate variability, optimizing the psychophysiological state of athletes depending on the type of sport, the number of sessions completed and the session variants chosen.

Pre-surgical features of intrinsic brain networks predict single and joint epilepsy surgery outcomes

Despite the effectiveness of surgical interventions for the treatment of intractable focal temporal lobe epilepsy (TLE), the substrates that support good outcomes are poorly understood. While algorithms have been developed for the prediction of either seizure or cognitive/psychiatric outcomes alone, no study has reported on the functional and structural architecture that supports joint outcomes. We measured key aspects of pre-surgical whole brain functional/structural network architecture and evaluated their ability to predict post-operative seizure control in combination with cognitive/psychiatric outcomes. Pre-surgically, we identified the intrinsic connectivity networks (ICNs) unique to each person through independent component analysis (ICA), and computed: (1) the spatial–temporal match between each person’s ICA components and established, canonical ICNs, (2) the connectivity strength within each identified person-specific ICN, (3) the gray matter (GM) volume underlying the person-specific ICNs, and (4) the amount of variance not explained by the canonical ICNs for each person. Post-surgical seizure control and reliable change indices of change (for language [naming, phonemic fluency], verbal episodic memory, and depression) served as binary outcome responses in random forest (RF) models. The above functional and structural measures served as input predictors. Our empirically derived ICN-based measures customized to the individual showed that good joint seizure and cognitive/psychiatric outcomes depended upon higher levels of brain reserve (GM volume) in specific networks. In contrast, singular outcomes relied on systematic, idiosyncratic variance in the case of seizure control, and the weakened pre-surgical presence of functional ICNs that encompassed the ictal temporal lobe in the case of cognitive/psychiatric outcomes. Our data made clear that the ICNs differed in their propensity to provide reserve for adaptive outcomes, with some providing structural (brain), and others functional (cognitive) reserve. Our customized methodology demonstrated that when substantial unique, patient-specific ICNs are present prior to surgery there is a reliable association with poor post-surgical seizure control. These ICNs are idiosyncratic in that they did not match the canonical, normative ICNs and, therefore, could not be defined functionally, with their location likely varying by patient. This important finding suggested the level of highly individualized ICN’s in the epileptic brain may signal the emergence of epileptogenic activity after surgery.

Technological solutions are environmentally friendly safe watering with wide-ranging sprinkler machines

Erosion processes in the Russian Federation remain one of the main sources of loss of soil and crop fertility resources, deterioration of land conditions. The implementation of an environmentally safe irrigation process with wide-coverage sprinklers is an urgent problem and requires improvement of technology, technological techniques for soils with low water permeability. The aim of the study was to optimize the operating mode and technological methods of irrigation with wide-reach sprinklers, adaptation to conditions changing during the irrigation period, exclusion of over-watering and water erosion of soils. The article discusses the schemes of differentiated distribution of irrigation norms and the movement of wide-reach sprinkler machines of circular and frontal action, ensuring compliance of the irrigation norm with the level of moisture reserves of field areas at the time of their watering, reducing the environmental burden on the soil and preserving fertility.

Consistency of trends in the economic and energy development of Ukraine: Assessment and analysis

Reforming Ukraine’s energy sector is targeted at the implementation of European legislation into national practice. However, the lack of a vision of the country’s energy model, coordinated with trends and priorities of its economic development, is creating a number of problems with its energy supply. The aim of the presented study is to assess the consistency of trends in the economic and energy development of Ukraine. To achieve the goal, a methodological approach to assessing the consistency of trends and structural changes in the economy and energy sector was developed. It was proposed to carry out the assessment based on the analysis of the resource / commodity and production / consumption chains of the electric power industry, and the conditions of the electric power market. It was proved that the trends and structural changes in the economy of Ukraine were not accompanied by corresponding changes in the energy sector of the country. Such inconsistency conditioned: a low level of utilization of installed power generation capacities and, consequently, a high level of unused power generation reserves; a high level of power generation reserves that determined a significant level of non-productive costs and, consequently, a high total cost of power production.

Insurance companies in the European Union: General criteria affecting investment policies

Investments of insurance companies relate to assets that guarantee the insured the payment of benefits (liabilities assumed), so they are conditioned by the duration of contracts, the amount of the sums insured, and the level of technical reserves required. An entity shall preserve the value of the investment in time for benefits obligations to policyholders and maintain the solvency margin and capital to protect shareholder or participant/beneficiary. Some insurance investment policies are based on the consideration of risk and return on assets and have incorporated the outcome measures of investment expenses and cost of capital. This article provides an overview of the evolving investment strategies of insurers and identifies the opportunities and constraints they may face with respect to long-term investment activity. This research employs a qualitative method with a convenience sampling approach. The sample of this study was the portfolios of several insurance companies in the European Union (EU). The results showed that two types of general criteria when selecting investment assets are observed, at least theoretically: the ownership structure of the entities and the types of products that are managed (life and non-life). According to the results of this study, most of the investments correspond to the life insurance segment, where contractual obligations are long-term and the insured risk is less volatile, which are invested mainly in fixed income. In contrast, non-life entities have a greater preference to invest in equity and real income when compared to the previous. The relevance of this study is based on the repercussions in the financial markets, as insurers as the main institutional investor.

Digital affinitiy and cognitive reserve: Salience for resilient aging in pandemic.

Objective: The study aimed to analyze the impact of technology in the older adults after acute pandemic regarding to the development of digital confidence. Method: A sample of n. 56 healthy older adults (N = 22 female, N = 34 male) aged 64 to 86 years (M = 73.7, SD = 6.40) participated in observational study. The sample was distributed in two groups: (a) pre-COVID and (b) post-COVID. Psychological battery was applied: Mini-Mental State Examination, Cognitive Reserve Index Questionnaire, Beck Depression Inventory-II, Affinity for Technology Interaction Scale, and then Digital Mastery Questionnaire. Descriptive and (M)ANOVA statistical analyses have been applied. Results: Our results confirmed the increase in technology usage among elders, the higher use of smart devices and then more confident digital daily living; then, the improving of digital affinity for technology and higher adherence in seniors than older. In sex effect, men seemed developing higher digital confidence for digital experience, for access and use of financial online services than women. In the process of improvement by massive digital experience in daily living the cognitive reserve had relevant influence: elders with high level of cognitive reserve appeared to enhance own competence in digital mastery and affinity for technology. Conclusions: Our study highlighted the higher cognitive reserve being protective in older adults favoring the efficacy to the changing in daily living as well the develop of adaptive behaviors in order to achieve high Quality of Life.

The Role of International Reserves in Sovereign Debt Restructuring under Fiscal Adjustment

Highly indebted developing economies commonly also hold large external reserves. This behavior seems puzzling given that governments in these countries borrow with an interest rate penalty to compensate lenders for default risk. Reducing debt to the same extent as reserves would maintain net liabilities constant while decreasing interest payments. However, holding reserves can have insurance benefits in a financial crisis. To rationalize the levels of international reserves and external debt observed in the data, a standard dynamic model of equilibrium default is extended to include distortionary taxation and debt restructuring. This paper shows that fiscal adjustments induced by sovereign default can generate large demand for reserves if taxation is distortionary. At the same time, a non-negligible position in reserves modifies the debt restructuring negotiations upon default. A calibrated version of the model produces recovery rate schedules that are increasing with reserves, as seen in the data, being also able to replicate large positions of reserves and debt to GDP. Finally, I study how both mechanisms play a key quantitative role to generate such result, in fact, not including them, produces a counterfactual demand for reserves that is close to zero.

РОЛЬ МОНЕТАРНОЇ ПОЛІТИКИ В СИСТЕМІ ЗАБЕЗПЕЧЕННЯ ФІНАНСОВОЇ СТАБІЛЬНОСТІ ДЕРЖАВИ

This article examines the role of monetary policy in the system that ensures the financial stability of the country. Monetary and credit policy is an important part of the economic policy of the National Bank, which is aimed at ensuring price stability, creating appropriate conditions for the economic growth and development of the country, and increasing the level of employment of the population. Ensuring the stabilization of the national economy requires the implementation of a set of measures aimed at managing individual elements of economic development. The implementation of a successful monetary policy and its impact on national economic security depends on the achievement of tactical, medium-term and final goals. Among the main directions of monetary policy, the following final goals can be identified, which are directly related to the level of national economic security: growth of real production, moderate expected inflation, balance of international payments, maximum employment. The main tools of wartime monetary policy are defined and the necessity of implementing wartime monetary policy is revealed. War always causes significant damage to the economic and financial stability of the country. One of the most striking consequences of this is the strong inflationary pressure in Ukraine after Russia’s military aggression. This economic indicator seriously affected the life of the population and the general economic development of the country. The priorities of the monetary policy of the National Bank of Ukraine during the war years are the maximization of Ukraine’s defense needs and the reliable functioning of financial markets, ensuring the smooth operation of the banking and payment systems, curbing inflation and maintaining the economic stability of the hryvnia, and ensuring the necessary level of international reserves. The facts confirm that monetary policy is a catalyst for ensuring the country’s financial security and plays an important role in this process. The economic difficulties that Ukraine will face after the war require a number of measures to ensure macroeconomic stability and prevent panic. These measures need to be studied in detail in future studies.
