ABSTRACT
 Education has a great stake in the building of a nation's civilization. Meanwhile, efforts to build a nation's civilization must start from the formation of the character of early childhood groups, because this generation will play a lot of role in determining the direction of the nation's journey in the future. Based on this thesis, early childhood education becomes an important discourse in the world of education. Because of the urgency, religion (especially Islam) discusses many issues of early childhood education. The Hadith of the Prophet (peace be upon him), as one of the sources of Islamic teachings, is also not quiet from discussions related to early childhood education, including discussions about the method of educating early childhood. This paper attempts to provide information about the methods of early childhood education of the Hadiths of the Prophet (peace be upon him) which are explored by methods of understanding substantive philosophical hadith. As a result, the prophet's method of early childhood education is a method of preaching, a method of dialogue or discussion, a method of story, a method of demonstration, as well as a method of reward and punishment.

SOLVING FORM TWO STUDENTS’ FAILURE TO SUBTRACT DIRECTED NUMBERS IN MATHEMATICS: AN ACTION RESEARCH STUDY
Authors: Sylocious Chaturuka , Silvanos Chirume
Published: June 2023

The purpose of this action research was to solve student’s failure to subtract directed numbers in Mathematics at junior secondary (Form Two) level. The study was conducted at a secondary school in Gweru, Zimbabwe. The research had two cycles. Cycle 1 had four participants, while Cycle 2 had one participant whose problem had not been solved in Cycle 1. Cycle 1 had three sessions: structured interview, implementation of the cooperative strategy and evaluation of the effectiveness of the cooperative strategy. The cooperative strategy was used in conjunction with the number line and the ‘having money-owing money’ techniques. Cycle 2 had two sessions namely: implementation of the counters model and evaluation of the effectiveness of the strategy. Results from the implementation of the cooperative strategy indicated that logical sequencing of concepts, group work and good presentation skills reduced possible misconceptions. The major reflection was that although the participants had seemed to have the same problem, the use of one strategy may not be effective as was the case for participant D. The results from the interviews highlighted the importance of continuously checking with the learners to reflect on the teacher’s practices. Results from the ‘two-colour counters’ showed the effectiveness in maintaining interest, motivation and concentration. The major limitation of the study was that the number line and the counters model were difficult to use, time consuming and laborious when large numbers were involved. The research has implications on the teaching and learning of directed numbers involving integers, fractions, decimals and algebraic expressions. A call for further research is also made.
Problem of plane strain state of two-layer body in dynamic elastic-plastic formulation (Part II)
Authors: Bogdanov Vladislav
Published: June 2023

Composite materials are widely used in industry and everyday life. Mathematical modelling of composite materials began to be actively developed in the 50s and 60s of the last century. Composite materials began to be actively used in industry only at the end of the 70s of the last century. From that time to this day, interest in composite materials has not weakened, and the demands of modern industry and production are constantly increasing. The areas and branches of application of composite materials are expanding. Many different methods are used to calculate and develop composite materials. This article is part two of the previous article, where there is an investigation of the contact problem of the interaction of a striker with a two-layers composite base in a dynamic elastic-plastic mathematical formulation. This composite base is rigidly attached to an absolutely hard half-space. Its first (top) layer is made of steel, and the second (bottom) layer is made of glass. Glass is a widely available cheap amorphous material, the properties of which cannot be degraded as an result of aging, corrosion, and creep processes. The glass layer can be strengthened by reinforcement and hardening. Therefore, composite materials made on the basis of glass are important in modern production; their use gives a great economic benefit. Rigid adhesion of the layers to each other is assumed. The impact process was modelled as a non-stationary plane strain state problem with an even distributed load in the contact area, which changes according to a linear law. The fields of the Odquist parameter and normal stresses were studied depending on the size of the contact area. In this article as in part I for the design of composite and reinforced material the non-stationary contact problem of plane strain state has been solved in more precise elastic-plastic mathematical formulation. To consider the physical nonlinearity of the deformation process, the method of successive approximations is used, which makes it possible to reduce the nonlinear problem to a solution of the sequences of linear problems.

In contrast to the previous article (Part I), in this papers there is an investigation of the strain-stress state, the fields of the Odquist parameter and normal stresses depending on the thickness of the first (upper) steel layer.
Quartz sand is an affordable inexpensive raw material for technologies of electronics and photovoltaics
Authors: Kritskaia Tatiana , Sukach Mykhailo , Bazhenov Yevgen
Published: June 2023

Based on the analysis of modern methods for obtaining semiconductor silicon, critical factors influencing the prospects for the development of the industry are identified. The basic component of the production scheme for producing silicon of semiconductor quality today is the carbothermal technology for producing metallurgical silicon. The dominance of this scheme is largely dictated by economic reasons for the development of capital-intensive industries. The accumulation of objective needs over time predetermine the need to overcome the inertial barrier of evolutionary steps in the development of semiconductor quality silicon technology.

First of all, the problems of raw material supply and high energy intensity of traditional production processes are actualized. The task is formulated in the direction of searching for a source of raw materials that removes in the time perspective the problems of ensuring a potential increase in the volume of production of semiconductor quality silicon, as well as the problems of energy supply for this growth process. As a promising solution, a method is proposed for obtaining silicon of semiconductor quality directly from quartz sand, excluding the use of expensive and scarce quartzites and charcoal. The prospects for quartz sand as a raw material replacing quartzite are objectively predetermined by the high similarity of the physicochemical characteristics of these materials. The objective prerequisites for the process of replacing quartzite are supported by the existing practice of testing the proposed technological solutions on an industrial scale.For this purpose, low energy-intensive processes for the production and purification of silanes, utilization and reversal of intermediate technological products are used. The energy efficiency of the method is ensured by the exclusion from the technology of a large-tonnage, energy-intensive process for obtaining metallurgical silicon, as well as energy-consuming methods associated with the use of low temperatures (–30 ... –80 ° C). The technological solution eliminates the need for the synthesis of hydrogen chloride and, accordingly, eliminates the explosive high-temperature process from production. The proposed solutions open up possibilities for the variable use of known technologies in relation to the current consumer requirements for the quality of polycrystalline silicon.

A partir de la teoría epistémica laica se desprende el concepto de Necesidad de Cierre Cognitivo el cual contempla los elementos cognitivos y motivacionales subyacentes de los individuos en la construcción y uso del conocimiento, así como también en la toma de decisiones y búsqueda de información. El constructo admite un gradiente que va desde una alta necesidad de cierre cognitivo, es decir, buscar respuestas definitivas y específicas y reducir estados de incertidumbre, a una baja necesidad de cierre cognitivo, el cual permite coexistir con diversas explicaciones causales y tolerar la ambigüedad. Dicho constructo está constituido por dos dimensiones, la tendencia a la urgencia, la cual se caracteriza por un estado de búsqueda rápida de información, y la tendencia a la permanencia la cual busca congelar y volver impermeable la información alcanzada. Las teorías conspirativas, a su vez, han permitido adjudicar un sentido a la experiencia cuando las condiciones parecen inciertas y aleatorias. Cumpliendo la función de observar el mundo como algo ordenado y predecible. En relación a la influencia de la NCC en el procesamiento de la información, el presente trabajo buscó realizar un estudio exploratorio acerca de la existencia de posibles relaciones con las teorías conspirativas. Se utilizó el Test-Revisado de Necesidad de Cierre Cognitivo (TR-NCC) y la escala de Teorías Conspirativas Genéricas (GCB) en una muestra de 267 participantes. Los resultados favorecen la relación entre la tendencia a la urgencia y a ciertas dimensiones del GCB.

Reletions between partial moduli of smoothness of functions with monotone Fourier coefficients
Authors:   Volgograd State Technical University, Simonova I.E. , Simonov B.V. ,   Volgograd State Technical University
Published: June 2023

The problem of estimating the moduli of smoothness of functions from Lqin terms of moduli of smoothness from the broader Lebesgue class Lph as been known for a long time. At the initial stage, in the works of Titchmarsh, Hardy, Littlewood, Nikolsky, the properties of functions from Lipschitz classes were studied and the corresponding embeddings were obtained. For moduli of continuity of functions of one variable P.L. Ulyanov proved an inequality later named after him - "Ulyanov’s inequality". The classical Hardy-Littlewood embedding for Lipschitz spaces is a consequence of Ulyanov’s inequality. As V.A. Andrienko showed, Ulyanov’s inequality is exact in the scale of classes Hωp. Further development of this direction is connected with the works of V.A. Andrienko, E.A. Storozhenko, M.K.Potapov, L. Leindler, V.I. Kolyada, P. Oswald, N. Temirgaliev, S.V. Lapin and other mathematicians. Kolyada proved that Ulyanov’s inequality can be strengthened and proved the corresponding "Kolyada’s inequality". Kolyada’s inequality is exact in the sense that there exists a function in Lp with any given order of the modulus of continuity for which this estimate cannot be improved for any value of δ .Yu.V. Netrusov, M.L. Goldman and W. Trebelz extended Kolyada’s inequality to the moduli of smoothness of higher orders. Another direction of research was the study of fractional moduli of smoothness in the works of M.K. Potapov, B.V. Simonov, S.Yu. Tikhonov. This made it possible to strengthen the Ulyanov inequality and showed the specificity and special significance of using fractional moduli of smoothness, without which, as it turned out, it was impossible to obtain final results. In this article, we study partial moduli of smoothness of functions of two variables. Inequalities are obtained that extend Kolyada’s inequality to partial moduli of smoothness for functions with monotone Fourier coefficients. Estimates are also obtained for the partial moduli of smoothness of the derivative ofa function with monotone Fourier coefficients in terms of the partial moduli of smoothness of the original function.

In modern conditions of digital technologies implementation in various sectors of the economy, the digitalization of public administration, healthcare, education, and science, the growth in the number of Internet services and mobile devices the issues of ensuring the security of cellular communication systems are becoming increasingly relevant. It is becoming increasingly difficult to detect multiple and complex cyber security threats as the sources and methods ofcyber-attacks evolve and expand. Classic network attack detection approaches that rely heavily on static matching, such as signature analysis, blacklisting, or regular expression patterns, are limited in flexibility and are ineffective for early anomaly detection and rapid response to information security incidents. To solve this problem, the use of machine learning (ML) algorithms is proposed. ML methods can provide new approaches and higher rates of detection of malicious activity on the network. In this work, the Splunk Enterprise data analysis platform and the Splunk Machine Learning Toolkit for creating, training, testing, and validating a network attack classifier are used. The performance of the proposed model was evaluatedby applying four machine learning algorithms such as a decision tree, a support vector machine, a random forest, and adouble random forest. Experimental results show that all used ML algorithms can be effectively used to detect network attacks, and the double random forest method has the best accuracy in detecting distributed denial-of-service attacks.

Computed tomography is a vital need to know the structure of the inside of the body from the information obtained from its transillumination without destroying the shell. The format presented here forsolving this massively understandable problem, which can only be theoretical and mathematical with subsequent engineering implementation, is fundamentally expressed in the approximate formula established by the authors in 2019 in approximate formula on a plane with a two-dimensional Cartesian coordinate system. In this article,this breakthrough is brought to a complete surprise in the equivalence of the fundamental problems of Computed Tomography and both widely known and developed in new content continuations of the problems of recovery functions by operators of the form of finite convolution of values approximated at the grid nodes with specially constructed kernels: \[sup\left\{{\left\|f\left(x\right)-\sum^N_{k=1}{{\left(R^2\right)}^{-1}Rf\left({\xi }_k\right)}R\left(\textrm{Ф}\left(y-{\xi }_k\right)\right)(x)\right\|}_{W^{{\left\|y\right\|}^{\frac{s-1}{2}}}_2\left(S^{s-1}\times R^1\right)}: f\in W^{әlpha \left(y\right) \cdot{\left\|y\right\|}^{\frac{s-1}{2}}}_2\left(S^{s-1}\times R^1\right)\right\}әsymp \] \[әsymp sup\left\{{\left\|f(x)-\sum^N_{k=1}{f\left({\xi }_k\right)}\textrm{Ф}(x-{\xi }_k)\right\|}_{L^2\left(E_s\right)}: f\in W^{әlpha \left(y\right)}_2\left(E_s\right)\right\},\] As is customary in Mathematics (in other sciences too), any claim for a breakthrough must be demonstratedin results of fundamental importance. In the resulting equivalence, the working part turned out to be in astate of enough for illustrative and, necessary, fundamental conclusions readiness according to the ComputerScience offered by the first author (according to the list) in 1996 and filled in Kazakhstan with far from trivialcontent of the Computational (numerical) diameter (C(N)D). Namely, a wide range of developments in thetheory of C(N)D instantly automatically leads to new theoretical and direct practical applications of advances in Computed Tomography, including analytic expressibility in explicit formulas of the computational aggregates of Tomography in terms of scanned quantities. Among them is also the conclusion that in Computed Tomographythere is no better scanning method than the Radon transform.

The purpose of the study is to analyze and systematize existing research on the history of tourism and to form one’s own view on the problematic of the issue. This is relevant in connection with the understanding that the development of tourism mirrors the historical, socio-economic and cultural development of society. The methodological basis of the article is the principles of methodological pluralism. A number of scientific methods and approaches have been used to the extent that they are adequate to the tasks of the research. The author uses a system of general philosophical (dialectics, objectivity, historicism), general scientific (method of system analysis, structural-functional, retrospective-comparative), and special (formal, comparative, statistical) research methods. Scientific novelty. The article substantiates theoretical-methodological, methodical approaches and developed practical recommendations for the balanced development of the tourism industry in Ukraine. Based on the study of tourism development trends, a scientific approach to the development of the potential of the tourism industry (based on the results of cognitive modeling) is proposed, which includes structural units of a specialized management center and support for the balanced development of the tourism industry. Conclusions. It is shown that the origin of tourism took place in distant antiquity. The formation of tourism as an independent organized activity occurred in the 1970s, this alternative type of employment was stimulated in order to stop the mass migration of the population from the countryside to the city. It is emphasized that the formation of tourism in different geographical regions has certain features, its development can take place according to the following main models: Anglo-American, Asian, Western European, Eastern European. Attention is focused on the fact that in many countries, the activity of providing tourist services is stimulated by state bodies and is aimed at supporting unpromising areas.

The purpose of the article is to consider aspects of the development of the restaurant industry in Ukraine. Today, in Ukraine, not only the quality of products, but also the provision of services and appropriate service in various spheres of activity is of great importance in the restaurant industry. The provision of services is something that combines the organization of meals and recreation with elements of additional service and is an integral part of the activity of restaurant establishments. Providing services of higher quality, in comparison with competitors, is one of the priority directions for the formation of strategic competitive advantages. It should also be noted that the provision of services should not only satisfy the needs of consumers, but also exceed their expectations. It is because of this that the owner or relevant specialists of restaurant establishments need to conduct an analysis of their target audience more often in order to identify the needs and expectations of customers as accurately as possible. The methodology is based on the principles of systematicity and scientificity. Such methods as analytical-synthetic, the method of comparative analysis were used. Scientific novelty. In the scientific study, the attention is focused on the advanced study of the development of the restaurant industry in Ukraine, the analysis of influencing factors and the forecasting of its development prospects.

The Role of Protein Kinase C in the Supraesophageal Ganglion of Female Acheta Domesticus
Authors:   ,   Andrews University, Kim Sunny
Published: June 2023

The phonotactic response of female Acheta domesticus to the male's calling song is modulated by hormones. The presence of Juvenile Hormone III in the supraesophageal ganglion causes crickets to be more selective. This project evaluates the possibility of a second messenger system involving protein kinase C as the molecular mechanism of Juvenile Hormone III control. A solution of Juvenile Hormone III and a protein kinase C blocker was nanoinjected into the supraesophageal ganglion of nselective female crickets, causing them to remain unselective. This suggests that Juvenile Hormone III utilizes a protein kinase C-mediated second messenger system.
The Effect of 4-aminopyridine on Phonotactic Selectivity in Female Crickets
Authors:   ,   Andrews University, Martin Lauren
Published: June 2023

My research project was designed to explore the effects of 4-aminopyridine (a potassium channel blocker) on phonotactic selectivity in female crickets, Acheta domesticus. These crickets underwent pre-tests for selectivity on a non-compensating treadmill during which their response to a range of male calling songs (30-90ms syllable periods) was recorded. A solution of 9.2 nl of saline or 10(-5)M 4-aminopyridine was nanoinjected into the supraesophageal ganglion. After a ten-minute recovery period, post-tests were performed, identical to the pre-tests. There was no significant effect of 4-aminopyridine on the females' selectivity.
Semiotic Analysis of Andrews University's Official Seal
Authors:   ,   Andrews University, Francis Debbie-Ann
Published: June 2023

This essay focuses on the significance of the symbols used within the official seal of Andrews University. The official seal of an institution describes the origins, foundations, and the authority that the institution carries. The analysis focused on these particular sections: "Andrews University," "1874," and the pyramid. A concise analysis was made on the other elements of the seal: the colors blue and gold, Corpus, Mens, Spiritus; and the cross-like structure within the middle of the seal. Past and current university personnel were consulted for interviews and for clarification of material. The results revealed that the official seal of Andrews University carries an arbitrary and mythic significance to the institution.
The Effects of Pyrilamine on the Selectivity of Phonotaxis
Authors:   ,   Andrews University, Chung Kristin
Published: June 2023

Hormones modulate phonotactic behaviors of female crickets (Acheta domesticus). This project seeks to observe the changes in phonotactic behavior when anti-histamine is injected in the prothoracic ganglion. The anti-histamine used, pyrilamine, resulted in older, unselective females becoming more selective to the male calling songs. Females injected with saline (controls) remained unselective. The experiments with pyrilamine (anti-histamine) validates histamine's proposed role on phonotactic selectivity by enhancing inhibition of syllable period selective neural circuits in the prothoracic ganglion.
Intraindividual Variation in the Calling Songs of the Cricket Gryllus Pennsylvanicus
Authors:   ,   Andrews University, Van Putten Lauren
Published: June 2023

The goal of this project was to examine intraindividual variability in the calling song of the male cricket, Gryllus pennsylvanicus. We evaluated syllable period and chirp period lengths under both constant and changing temperature conditions. Significant variability in chirp and syllable period length was found under constant conditions, suggesting males are subject to internal variability without any effects from the environment. Significant variability was also seen in chirp and syllable period length for crickets under changing temperature conditions. There was a two to five minute delay in response to the temperature change.
Auditing's Ripple Effect: Divergence After Enron
Authors:   ,   Andrews University, Wolff Kelley
Published: June 2023

The Enron scandal received considerable attention over the past 10 years (2001-2011), and the fallout from Enron, WorldCom, and Adelphia were severe. Both auditors and accountants lost the trust of the government and the public. This caused the government to intervene by enacting the Sarbanes-Oxley Act and creating the Public Company Accounting Oversight Board to oversee the audits of public companies. This study will examine how the differences in perspectives amongst gender, as well as public and GCAS auditors, factors into personal opinions by admistering a research survey and studying literature surrounding the Enron scandal.
Chaos, Fragility, and Change: Revisiting Laura Wingfield
Authors:   ,   Andrews University, Weiso Lydia
Published: June 2023

The Glass menagerie (1944) by American playwright Tennessee Williams is a memory play focused on the Wingfield family of St. Louis. The play develops themes of family dysfunction, failed expectations, and various attempts to escape reality. This project focuses on the character of Laura Wingfield, an introverted, emotionally fragile character who is almost always interpreted as helpless and tragic. However, though a close critical analysis of Laura's interactions with other characters and with key props such as her glass collection, the family's Victrola and candelabra, this project shows that Laura need not be viewed as tragically as critics typically have read her.
Ataraxia: A Modern Platonic Utopia
Authors:   ,   Andrews University, Burton Jeremy
Published: June 2023

My research focuses on the effects on children raised according to the guidelines for training the Guardians of the ideal society described in Plato's Republic. I explore this concept creatively in a fictional modern Utopian community like that of B. F. Skinner's Walden Two and support this with firsthand accounts of the attempts to make Skinner's work a reality. Combined with a perspective on education in Plato along with the Hitler Youth program, this framework allows me to analyze how we use ideals and philosophy to justify our actions, and ultimately how human nature confounds our attempts to build paradise.
Inerrancy and Sovereignty: a Case Study on Carl F. H. Henry
Authors:   ,   Andrews University, Karanja Joseph
Published: June 2023

Problem This study examines how the concept of inerrancy of Scripture presupposes a particular understanding of divine sovereignty. Investigation is based on the writings of Carl F. H. Henry, a contemporary American evangelical theologian. Method This investigation uses case—study approach. It consists of a descriptive analysis of Carl Henry's concepts of inerrancy and sovereignty as individual concepts and the sense in which the former presupposes the latter. General inferences are based on that analysis. Results This study shows that Henry's concept of sovereignty is an indispensable presupposition in his concept of inerrancy. Among other things, sovereignty denotes Gad's absolute causality, thereby providing the theological grounds on which scriptural inerrancy is predicated. Conclusions The concept of inerrancy is best explained in theological contexts where divine sovereignty is affirmed and understood in absolute causal terms.
