Authors: Guan Zheng , Ding Gangyi , Aljuhani Hosam Lafi , Huang Tianyu 
Published: February 2022

Abstract
The completeness of the complex model is an important index to evaluate the pros and cons of the complex model. It is of great significance to study the objective evaluation under different indicators and construct an indicator system to ensure the integrity of the complex. The construction of complex system indicators requires instructors who can fully describe the functions of complex models. This study designs a complex index EX
, proves its authenticity through comparison with the real world, illustrates its similarity through conflict and comparison with the coverage of the target problem, and describes its intelligence level through confrontation and comparison with other complex models. Research on complex model problems based on the derivation process of domain theory proves that the quantified complete distance EX
can calculate the similarity between the model and the actual environment to evaluate ‘true and false’. The experiment proved to be a reliable and complex model verification indicator.
Regression function model in risk management of bank resource allocation
Authors: Zhang Hongzhi 
Published: February 2022

Abstract
Commercial bank asset-liability management is a method of overall risk control and resource allocation. It has an essential impact on commercial banks’ operational safety and affects the stability of a country's overall financial system due to the domino effect. The article chooses the regression function model to measure the expected default frequency (EDF) in the resource allocation risk of Chinese banks. It analyses the transmission process of the impact of the main macroeconomic variables on the EDF of the resource allocation risk of Chinese commercial banks. The study found that under the significance level of 5%, standardised industrial output growth rate, money supply growth rate, and real estate price index are the main reasons for the changes in bank resource allocation risk EDF.

Authors: Ma Yanran , Chen Nan , Lv Han 
Published: February 2022

Abstract
Due to the extremely volatile nature of financial markets, it is commonly accepted that stock price prediction is a task filled with challenges. However, in order to make profits or understand the essence of equity market, numerous market participants or researchers try to forecast stock prices using various statistical, econometric or even neural network models. In this work, we survey and compare the predictive power of five neural network models, namely, back propagation (BP) neural network, radial basis function neural network, general regression neural network, support vector machine regression (SVMR) and least squares support vector machine regression. We apply the five models to make price predictions for three individual stocks, namely, Bank of China, Vanke A and Guizhou Maotai. Adopting mean square error and average absolute percentage error as criteria, we find that BP neural network consistently and robustly outperforms the other four models. Then some theoretical and practical implications have been discussed.
Higher education innovation and reform model based on hierarchical probit
Authors: Chang Jingying , Lan Weibin , Lan Wenhao 
Published: February 2022

Abstract
With the intensification of social competition, the rate of return to education is gradually decreasing. This leads to a reduction in the indirect effect of education on happiness. This article uses the bivariate ordered Probit model under the educational field theory to investigate the impact of higher education innovation on social class and residents’ happiness. The results show that the innovation and reform of higher education will have a certain impact on residents’ happiness. The improvement of education level can significantly improve the individual's subjective well-being, and there are significant urban-rural differences. This shows that education reform and innovation are imperative.

Authors: Costa Yasmim Nathalie Carvalho , Pinto Thais Araujo , De Andrade e Santos Ayrton Hugo 
Published: February 2022

O concreto Auto adensável (CAA) é definido como aquele capaz de fluir, preencher a fôrma, passar por elementos embutidos (dutos, armaduras e insertos), e auto adensar-se pelo seu próprio peso, dispensando qualquer meio de vibração externa ou adensamento, ao mesmo tempo que mantém sua homogeneidade, nas etapas de produção, transporte, assentamento e acabamento. Esse concreto nos últimos tempos ganhou um importante papel na construção civil, principalmente com o crescimento do uso do sistema construtivo de parede de concreto, onde paredes de 10 cm de espessura, com alturas de 2,8 m e com presença de armação precisavam ser concretadas e o concreto tradicional vibrado não teria sucesso. Esse concreto tem sido estudado por diversos pesquisadores, com o intuito de melhorar o seu desempenho e a microssílica que é um pó fino com esferas de diâmetro 0,1 µm e 5,5 µm, considerada uma adição mineral altamente pozolânica pode contribuir com esses resultados. Assim, com o intuito de analisar a influência da microssílica no concreto auto adensável, este trabalho propõe estudar a adição de percentuais de 3, 9 e 15 de microssilica no concreto. Para tanto foram realizados testes no estado fresco e endurecido do concreto, conforme apresentado na metodologia deste trabalho. Os resultados mostraram que a microssílica até um certo percentual tende a aumentar a resistência à tração e à compressão do concreto auto-adensável, sendo indicado seu uso.

Authors: Gruzkiy Yuri 
Published: February 2022

The article is devoted to the study of the historical aspect of the public procurement institute formation in Ukraine. The article highlights the main stages of the public procurement sector development, namely: 1993 – 1996; 1997 – 1999; 2000 – 2008; 2008 – 2010; 2010 – 2014 and 2015 – present, the normative regulation of the public procurement sphere, which has undergone significant changes since the independence of Ukraine, has been studied. It is established that the authors approaches to the formation of public procurement are quite similar, scientists note a gradual transition from centralized production planning and distribution of material resources to bidding on a competitive basis, which introduced in Ukraine the institution of public procurement. Some of the scientific approaches to the definition of «public procurement» are considered, the relationship between the concepts of «public procurement» and «government order» is analyzed, and the process of «government procurement» transformation into «public procurement» is covered. It has been found that some researchers view «public procurement» as a part of government order, others believe that public procurement is a broader concept than government order, and another group of scholars emphasize that «public procurement» and «government order» institutions are separate and autonomous from each other, as indicated by the following main features that characterize them: purpose, entities, sources of funding, the legal form of relations. It is established that under modern conditions, public procurement is separate from the state order, so it is impractical to consider them as a method of implementation or part of the state order.
EDUCATIONAL ENVIRONMENT AS A FACTOR OF DEVELOPMENT AND ADAPTATION OF GIFTED CHILDREN
Authors: Panenkova Yuliia V. 
Published: February 2022

The modern tendencies of psychology of development determine priority of the personality orientated model in the context of which child’s personality and idea of his/her integral development acquire the special value. The ambiguousness of interpretation of the phenomenon of gift and complication of his diagnostics creates serious difficulties in forming of the gifted personality, maintenance of his/her individuality and opening of talent. The aim of our paper is to determine the conditions of the educational environment for the development and adaptation of gifted children, substantiate the relationship between giftedness and adaptability, and present the results of the developed model of the adaptation process of gifted children. The category of gift belongs to the most fundamental description of personality. Nowadays there is a row of approaches to its determination. Most scientists examine a gift as a quality transformation of capabilities, as individual originality of makings, as psychological pre-condition of creative development of personality. Essence of personality development of the gifted children is determined as totality of their subjectivity, consciousness and system of values. The gifted child, unlike other children, in a greater measure is provided with ability to achieve the excellent degrees of subjectivity, consciousness, system of values, self-development in condition of successful adaptation process. Adaptation of gifted children is understood by us as a process of manifestation and development of giftedness and formation of children’s individuality in the educational environment. The social situation of development, development of gift and adaptability of the gifted children are correlated with the formation of personal reflection and self-esteem, self-confidence, value consciousness, the formation of characterological personality traits – communication, confidence, emotional stability, self-control, and reluctance to aggression. The presented model of the adaptation process determines the conditions of the educational environment for the development and adaptation of gifted children constructive relationships in the contact social environment (gifted children, parents, teachers, peers) and educational activities that contribute to adaptation and disclosure of children's giftedness through the formation of personal qualities, self-esteem, self-awareness and self-affirmation, personal values and reflection. Awareness of personal values, their own achievements and their recognition are value determinants of the development of creative abilities and personal identity of gifted children. A level, quality originality and character of the development of children’s gift are the result of a difficult cooperation of abilities, pedagogical conditions of the educational environment and psychological mechanisms of personal self- development and self-realization.

Authors: Hurbanska Svitlana 
Published: February 2022

In this article the anthropocentric approach to the study of the national language picture of the world through the prism of linguistic and cultural interaction is offered; the role of non-equivalent vocabulary in the language and conceptual picture of the world is determined due to the theoretical and methodological principles of the linguocultural aspect of research. The accentuation of the human factor as one of the central ones in anthropocentric linguistics brings to the fore the need to study the problems of describing the language structure, as well as the tasks of comprehensive study of the language personality, capable of generating and understanding speech. The establishing of the relationship between the language and culture on the example of non-equivalent vocabulary promotes the revealing of the national cultural specifics of the researched units, and defining universal phenomena, that are inherent in each individual national cultural community. The linguocultural research involves in-depth study of language units, the semantic structure of which is marked by national specifics. The relevance of this research is defined by contrastive and typological approach to the analysis of language signs, especially non-equivalent linguistic material. Various mechanisms of the language and culture interaction on the example of non-equivalent vocabulary are studied, taking into account the urgency of this research, which is determined by the interest in modern linguistic works to the investigation of linguocultural concepts actualization in the process of сoncept space modeling.

Authors: Kocherha Svitlana O. 
Published: February 2022

The article is devoted to Mykhaylo Kryvyniuk (1871-1944), a scientist, a writer, a teacher, and a member of the social-democratic movement, who left a significant heritage in Ukrainian history and culture of the late nineteenth – early decades of the twentieth century. The main task of the article is to outline Kryvyniuk’ biographical connection with Ostroh and to characterize the uniqueness of his friendship with Lesya Ukrainka. The article outlines the ancient phenomenon of brotherhood, the cult of which was re-actualized by Lesya Ukrainka. The main milestones of Mykhaylo Kryvyniuk's biography have been identified, using documentary materials that were not taken into account before. In the article, it is analyzed the letters of Lesya Ukrainka and members of her family to Mykhaylo Kryvyniuk in which there are numerous touches that characterize his worldview beliefs and moral qualities. The writer's relationship with her friend and later a relative (sister's husband) is described. Special attention is paid to Lesya Ukrainka's poems dedicated to her brother. The article is pervasive in understanding the role of Ostroh in the formation of Mykhaylo Kryvyniuk. Emphasis is placed on his studies at the Ostroh Gymnasium and his stay in the Ostroh prison. Lesia Ukrainka marked Mykhaylo Kryvyniuk as a "soul of Ostroh", which was manifested in his mentality, aesthetic tastes, and love for historical Volyn. The conclusions emphasize that Mykhaylo Kryvyniuk, a native of a peasant family from Ostroh region, became a representative of the Ukrainian elite at a young age. His civic stance led to persecution by the tsarist government and the totalitarian Stalinist system. With his qualities and deeds, Kryvyniuk earned the deep respect of Lesya Ukrainka and all members of her family, proving himself a man capable of chivalrous deeds.
FACTORS INFLUENCING THE ORAL CAVITY OF PREGNANT WOMEN (OVERVIEW)
Authors: Чолокова Г.С. , Кенеева Ж.А. 
Published: February 2022

В обзорной статье приведены литературные данные о факторах, оказывающих влияние на стоматологический статус беременных женщин. Первые клинические признаки гингивита беременных наиболее часто возникают на третьем (16,99%) – четвертом (14,52%) месяцах беременности. Распространённость и интенсивность кариеса зубов у женщин, имевших две беременности и более, увеличивается в зависимости от возраста. С увеличением количества беременностей увеличивается интенсивность кариеса и воспалительных заболеваний периодонта. Прогрессирование воспалительно-инфекционных заболеваний пародонта является фактором риска таких осложнений во время беременности и родов, как преждевременные роды, рождение ребенка с малым весом, плацентарная недостаточность, преэклампсия. В первом триместре гестационного периода при превышении в ротовой жидкости уровня лактоферрина выше 3,08 мкг/мл, снижении содержания кателицидина ниже 1,9 пг/мл риск развития рецидивирования кариеса зубов повышается. Скорость прироста кариеса у беременных взаимосвязана с гигиеной полости рта, концентрацией общего и активного кальция в ротовой жидкости и в целом организме, полноценным и сбалансированным питанием. Профилактика кариеса зубов и болезней пародонта у беременных преследует двоякую цель: улучшить стоматологический статус женщины и осуществить антенатальную профилактику кариеса зубов.
The review article provides literature data on factors influencing the dental status of pregnant women: age, duration and number of pregnancies, hormonal and immunological status, general condition of the body, state of oral hygiene, nutrition.The first clinical signs of gingivitis in pregnant women most often occur in the third (16.99 %) – fourth (14.52 %) months of pregnancy. The prevalence and intensity of dental caries in women who have had two or more pregnancies increases with age. With an increase in the number of pregnancies, the intensity of caries and inflammatory periodontal diseases increases.The progression of inflammatory and infectious periodontal diseases is a risk factor for complications during pregnancy and childbirth, such as premature birth, low birth weight, placental insufficiency, preeclampsia. In the first trimester of the gestational period, the risk of recurrent dental caries increases if the level of lactoferrin in the oral fluid exceeds 3.08 μg / ml, the content of cathelicidin decreases below 1.9 pg / ml,. The growth rate of caries in pregnant women is interrelated with oral hygiene, the concentration of total and active calcium in the oral fluid and the whole body, complete and balanced nutrition. Prevention of dental caries and periodontal disease in pregnant women has a twofold goal: to improve a woman’s dental status and to carry out antenatal prevention of dental caries.
