Abstract
The treatment of patients with maxillary resection is most often carried out with prosthetic methods and means the main purpose of which is the restoration of masticatory and speech function. An important role in the treatment result is played by the correct planning of the type and shape of the prosthetic construction. In cases with large maxillary defects the main problems are related to ensuring the retention and stability of the prosthesis. The research analyses the opportunities for carrying out prosthetic treatment in patients with resection of half of the maxilla with an open obturator. The results showed that the reduced volume and weight of this type of prosthesis provide the necessary retention and stability. Important advantages are also the easy placement in the defect and the shortened period of adaptation.

Keywords: maxillary resection, maxillary defect, maxillary tumor, obturator.

Abstract
Despite the high level of instrumental provision in therapeutic dental procedures, which allows the use of modern technologies, a wide selection of filling materials, complications during endodontic dental treatment are not uncommon [1–3].

Noteworthy is not only the number of complications, but also a fairly frequent increase in the frequency of severe consequences of treatment, which lead to irreversible changes in the tissues of the maxillofacial area and disturbances in their function [4].

Keywords: filled dental canals, periodontal condition of the treated tooth, evaluation of endodontic treatment.

Qocayeva N. – LINEAR VS. NON-LINEAR CORRELATION ANALYSIS IN PREDICTIVE MODELING

LINEAR VS. NON-LINEAR CORRELATION ANALYSIS IN PREDICTIVE MODELING

Qocayeva N.
Nakhchivan State University

Abstract
This study presents a comparative analysis of linear and non-linear correlation methods within statistical modeling, employing synthetic datasets to explore their effectiveness under varying data conditions. Linear correlation, quantified by Pearson’s r, was found to be more effective in homoscedastic datasets, where the variance of one variable remains constant across the range of another. In contrast, non-linear correlation methods, particularly Spearman’s rho and Kendall’s tau, exhibited superior performance in heteroscedastic datasets, characterized by varying variances and more complex relationships. The research underscores the importance of selecting the appropriate correlation analysis method based on the specific characteristics of the dataset, as the use of an unsuitable method can lead to misinterpretation of data and analytical errors. These findings advocate for a nuanced, context-specific approach to correlation analysis, especially relevant in fields where understanding variable relationships is critical. The study also highlights the potential for future research, including the application of these findings to real-world data, the exploration of more complex data structures, and the integration of machine learning techniques for advanced correlation analysis.

Keywords: Correlation Analysis, Linear and Non-Linear Models, Statistical Modeling, Homoscedasticity, Heteroscedasticity.

Kyiv, Ukraine

Abstract
The article is devoted to the study of the issues of stimulation of foreign investment as a component of the state policy of foreign investment of Ukraine. In the process of research, the author concludes that stimulation is a set of methods of influence of state-authorized bodies on foreign investment processes, which are established by current legislation. The state enshrines in the provisions of the current legislation a system of legal and management measures, which are formed and implemented by special entities with the aim of regulating foreign investment relations for the socio-economic development of the state and which are carried out using a set of a number of methods, the application of which has a stimulating effect on foreign investors.

Based on the analysis of both scientific literature and the practice of investment activity, the author claims that the methods of state management and state regulation of foreign investment represent legally established methods of influence of management bodies on the object of management. Depending on the state’s chosen investment policy in the field of foreign investment, these methods can stimulate the activity of foreign investors. The incentive mechanism begins to operate when the use of one or another method creates more attractive economic conditions for foreign investors than those they have in other states.

Keywords: state policy of foreign investment, the concept of stimulation of foreign investment, types of stimulation in the content of the state policy of foreign investment.

Abstract
The article discusses the issue of recognition of ancient autocephaly and patriarchal dignity of the Georgian Church. The initiator of the process of recognition of ancient autocephaly and the patriarchal dignity of the Georgian Church was His Holiness Patriarch of Georgia Ilia II.

After many years of struggle, the final recognition of the autocephaly of the Georgian Orthodox Church occurred in 1990. On January 7, 1990, after a service in Zion, Metropolitan Chrysostomos, who visited Georgia, officially announced the decision of the Ecumenical Patriarchate to recognize the historical autocephaly of the Georgian Apostolic Church and the patriarchal title of its head.

Then Catholicos-Patriarch Ilia II spoke. In his sermon, he emphasized the fact that the Georgian Church has been autocephalous since ancient times and was headed by a Catholicos.

Keywords: Georgian Church, autocephaly, patriarchal dignity

Abstract
Cryptocurrency is a type of digital currency, accounting of which is provided by a decentralized payment system that does not have an internal or external administrator or any of its analogues, operating in a fully automatic mode. Сryptocurrency by itself does not have any special material or electronic form – it is just a number indicating the amount of data of the units of account, which is recorded in the appropriate position of the information package of the data transfer protocol that is often not even encrypted, like all other information about transactions between the addresses of the system. It is important to have an idea of what changes may occur with the prices of cryptocurrencies in the future in order to make informed decisions about the allocation of investments and also take into account the risks associated with investing in them. This, as well may be necessary for regulators and legislators to develop up-to-date legislative framework.

Keywords: cryptocurrency, pricing, assets, bitcoins, monetary unit, electronic currency, blockchain, volatility, crypto exchanges, inertia (momentum).

Abstract
From 20 to 30 percent of the population in developed countries is involved in agribusiness, thanks to which it remains one of the most budget-filling and profitable in the world.

Today, the agricultural sector is developing most strongly in the United States of America (up to 12 percent of GDP).

Since the European region cannot provide itself with agricultural products and raw materials in full, the agro-industrial complex is formed in such a way that global connections are taken into account.

Agribusiness in Ukraine has great potential for development, as it has the largest area of agricultural land in Europe (41.5 million hectares, or up to 70 percent of the total territory). About 25% of the world’s chernozem soils with a high level of fertility are concentrated in Ukraine. The agricultural sector accounts for more than 10% of GDP and is one of the most important export sectors. The agro-industrial complex is constantly developing, which is explained by the proximity of the main sales markets, the existing infrastructure, including transport, and the constant growth of global demand for food products.

Given that Ukraine is one of the world’s leading exporters of grain and oil crops, russia’s military invasion of our territory had a significant impact on agribusiness and food safety around the world.

Keywords: the food safety, modern challenges for the food safety.

Ablayeva A. – OVERVIEW OF THE POTENTIAL OF MICROALGAE FOR CO2 FIXATION

OVERVIEW OF THE POTENTIAL OF MICROALGAE FOR CO2 FIXATION

Ablayeva A.
2nd year doctoral student in the specialty “Environmental Protection Technology” ENU named after. Gumileva, Astana

Abstract
CO₂ forms the largest component in coal combustion flue gas (Xing Zhang, 2015). Carbon dioxide (CO₂) fixation is an important process in mitigating the harmful effects of climate change caused by greenhouse gas emissions. One promising method of CO₂ fixation is through the use of microalgae. These tiny organisms are capable of photosynthesis, converting light energy into chemical energy and fixing atmospheric CO₂ into organic compounds. Microalgae are known for their fast growth rates and high CO₂ assimilation rates, making them an attractive option for CO₂ mitigation. In fact, some species of microalgae can fix up to 10 times more CO₂ than land-based plants. Furthermore, microalgae can grow in a wide range of environments, including wastewater, saline water, and brackish water, making them versatile and sustainable. In addition to CO₂ fixation, Chlorella microalgae also remove other pollutants from flue gases, such as sulfur dioxide (SO₂) and nitrogen oxides (NOx). These pollutants can be toxic and contribute to acid rain and smog. Chlorella microalgae are able to remove these pollutants through a process known as bioadsorption, where the pollutants are adsorbed onto the surface of the microalgae. This review presents an outlook on microalgal propagation systems for CO₂ sequestration.

Keywords: Microalgae, CO₂ fixation, flue gas, utilization, photobioreactor.

Abstract
To clarify the nature of the chemical interaction between InAs₂S₂Se₂ and In₃As₂S₃Se₃, alloys of various compositions were synthesized. The chemical interaction in the InAs₂S₂Se₂-In₃As₂S₃Se₃ system was studied using complex methods of physicochemical analysis: differential thermal analysis (DTA), X-ray diffraction analysis (XRD), microstructural analysis (MSA), as well as determination of density and microhardness, and a Tx phase diagram was constructed. It has been established that the state diagram of the InAs₂S₂Se₂-In₃As₂S₃Se₃ system is quasi-binary, of the eutectic type. In the system at room temperature, solid solutions based on InAs₂S₂Se₂ reach up to 3 mol %, and based on In₃As₂S₃Se₃ up to 10 mol %. The compounds InAs₂S₂Se₂ and In₃As₂S₃Se₃ form a eutectic with a composition of 25 mol % In₃As₂S₃Se₃, temperature 265°C.
