Solution to Laplace’s Equation Using Quantum Calculus
Authors: Pintu Bhattacharya  , Ravi Ranjan
Published: October 2023

The quantum calculus emerged as a new type of unconventional calculus relevant to both mathematics and physics. The study of quantum calculus or q-calculus has three hundred years of history of development since the era of Euler and Bernoulli, and was appeared as one of the most arduous techniques to use it in mathematics as well as physical science. At present, it is used in diverged mathematical areas like number theory, orthogonal polynomials, basic hypergeometric functions, etc. Furthermore, in order to get analytical approximate solutions to the ordinary as well as partial differential equations, q-reduced differential technique and quantum separation of variable technique are used in mathematics, Mechanics, and physics. In this paper, Laplace’s equation, a well-known equation in both Physical and Mathematical sciences, has been solved extensively based on the basics of calculus, transformation methods, and q-separation of variable method. In addition, solutions to the Laplace’s equation as obtained by using different boundary conditions are revisited and reviewed. Consequently, all the necessary basics of q-calculus are displayed one by one, and thereafter, the process of finding its solution in view of quantum calculus is described extensively. In order to find out the exact solutions the dimensionality of all the parameters related to the problem has been described. As an essential outcome, it is also found that, as q tends to 1, the solution takes the form as it is in general physics. Hence, this article presents a review and extension that describe the solution to Laplace’s equation in view of both Leibnitz and quantum calculus. Thus, it can add a pedagogical exercise for the students of both physical and mathematical sciences to understand the usefulness of quantum calculus.

Beeswax, produced by honeybees by excreting from the abdominal glands, is a complex mixture of organic compounds. According to its chemical composition and properties, it belongs to the group of lipids. Waxes are, for the most part, monoesters of higher fatty acids with higher monohydroxyl alcohols. Determining the physico-chemical properties of beeswax is necessary for examining its quality and authenticity. The recommendation of the International Honey Commission (IHC) is that the basic physicochemical parameters for quality assessment and detection of possible adulteration are: melting point, acid value, saponification value, ester value and ester/acid ratio. In this paper, we examined the basic physical and chemical properties of authentic beeswax from domestic producers from three locations in Montenegro. The melting point of the investigated beeswax is in the range of 61.5-67.2 0C. The solubility of waxes at room temperature in organic solvents was the highest in chloroform and the lowest in acetone. The minimum and maximum value of the acid number of the tested beeswax was 18.2 and 28.6, respectively. The saponification value of the tested samples of beeswax was determined from 3 measurements and was: SV = 90.8 ± 16.1.

In this work, a series of phenolic N-acyl hydrazones was investigated in silico against six selected E. coli and S. aureus bacterial proteins. Generally, the obtained molecular docking results revealed significantly higher binding affinities of analogs a–n towards selected enzymes in comparison to standard compounds. In the case of E. coli proteins 1hnj, 1c14, and 6ntw, the lowest binding energies were calculated for derivatives l (-8.5 kcal/mol), d (-9.0 kcal/mol), and k (-8.2 kcal/mol), respectively. On the other hand, the highest binding affinity towards the S. aureus 3u2d, 1mwu, and 1jij enzymes was expressed by derivatives a, d, and j, with binding energies of -8.3, -8.4, and -9.4 kcal/mol, respectively. The obtained in silico results indicate the potential inhibitory activity of selected phenolic N-acyl hydrazone derivatives against E. coli and S. aureus bacterial proteins and represent a valuable ground base for future in vitro experiments.

Titanium dioxide nanoparticles (TiO2NPs) are widely used in pharmaceutics, food products and cosmetics. Besides numerous beneficial outcomes, they also induce toxic effects in different organs, including the eyes. The recent findings report that some surface modifications can attenuate TiO2NPs toxicity. Thus, the aim of this study was to compare the effects of acute oral treatment with commercially available, bare TiO2NPs and TiO2NPs surface modified with salicylic acid (SA-TiO2NPs) using adult Wistar rats as model organisms. Control animals were gastrically intubated with vehicle (0.01 M HCl), while others were treated with either TiO2NPs or SA-TiO2NPs (1000mg/kg dissolved in vehicle). Afterward, the mortality rate as the acute toxicity parameter and parameters of neurological function were assessed. Animals were sacrificed on the 14th day following treatment. In the eye crude synaptosomal fraction, the effects of treatments on oxidative stress markers such as prooxidant/antioxidant balance (PAB) and lipid peroxidation (LPO) were compared. According to the obtained results, the mortality was 0 in all experimental groups. TiO2NPs and SA-TiO2NPs treatments displayed mild effects on spontaneous activity and pacing and had no impact on the visual placing reflex. Moreover, TiO2NPs and SA-TiO2NPs exposure significantly elevated PAB levels, when compared to controls. Animals treated with SA-TiO2NPs had similar LPO levels as controls, while in TiO2NPs group LPO levels were significantly increased. The presented data showed that both examined nanoparticles exerted similar outcomes referring to most of the investigated parameters, however, surface binding of SA decreased the level of LPO and thus, mitigated some of TiO2NPs toxicity in the eyes.

Millions of European teachers represent an important intellectual power. They influence a huge pupil’s population, which is not homogeneous nowadays, they influence parent’s community, and they have respected impact on a society. It is necessary to underline that the global world in the 21st century brings about several changes that have to be implemented into the work of teachers and teacher training. Consequently, the roles and competences of teachers (with the stress on global competences), in comparison with the past, are changing (there exist a lot of reasons, e.g., inclusion of pupils with special needs, social inclusion and diversity in multicultural classes, diversity of pupils’ family settings, families at risk, new ICT in school and home environment, involvement of parents in schools, etc.). At present, there is a general agreement among researchers that competences for teaching profession have to be understood widely, not only as “teaching” competences (i.e., teaching in the class, carrying out the class instruction), but also as the process to equip student teachers with the current “teacher” competences. Main goal of this paper is to present how latest trends are implemented into the university professional training of student teachers in the bachelor study programme Pre-primary and primary education at Constantine the Philosopher University in Nitra and what kind of benefits they bring to the educational reality in kindergarten and primary school.
Dete i san u narodnim uspavankama
Authors:   University of Kragujevac, Faculty of Education in Užice, Stakić Mirjana M.
Published: October 2023

The purpose of sleep is to help children grow and develop, which is why many parents try to lull their children to sleep. The present paper investigates what types of feelings, desires, blessings and expectations from a childare contained in lullabies sung by different nations, as well as what perspectives on sleep and lulling a child to sleep there are. The corpus consists of 120 lullabies published in Milutin Đuričković‟s book “Zvezdice sna: uspavanke naroda sveta” (2021). The content analysis technique and descriptive method are used in analyzing the corpus. The obtained results show that the blessings and desires in the lullabies are concerned with the child‟s health, happiness and long life. They are related to dreams that come to life, which provides evidence for lullabies having a magic function. The expectations from a child show that the child was raised to fulfill the expectations of his/her family and the community. The analysis of the perspectives on sleep and lulling a child to sleep shows that emphasis is placed on the quality of sleep, the things that help the child go to sleep and the role of family, primarily that of mother, in creating optimum conditions for going to sleep and removing sleep distractions. The analyzed lullabies also contain a model of raising a child – encouraging the desired behavior (sleeping) by rewarding a child or punishing a child for misbehavior by frightening him/her as a means of reactive discipline. The analysis shows that the lullabies belonging to different nations have many elements in common. The fact that the lullabies used to have other functions besides the basic one suggests the need for further research.
Poimanje deteta, detinjstva, razvoja i učenja iz postmoderne perspektive
Authors:   The Academy of Applied Preschool Teaching and Health Studies, Kruševac  Serbia, Stamenković Ivana M.
Published: October 2023

The paper presents postmodern perspectives on child and childhood, development and learning, which rely on mutually intertwined starting points of poststructuralism, sociocultural theory, sociology of childhood and relational pedagogy. In order to advocate for childrenʼs rights and to support their well-being, it is very important to understand how specific socio-cultural-political context shapes childrenʼs lives, identities, development and learning. Аdditionаlly, the paper indicates the significance of continuous critical reexamination of dominant discourses about child and childhood, child’s nature and children’s needs, what children are, can be and should be, what is natural, normal and necessary in development, as well as how children learn, how they should learn and what is important for learning. Since the educational practice depends on existing beliefs and constructions, emphasis is placed on problematizing, deconstructing and reconstructing discourses that are taken “for granted”.

Published: October 2023

In the era when the modern concept of childhood and the inviolability of the child’s right to education are in the spotlight, and with good reason, numerous questions and pedagogical paradoxes regarding play and toys during a child’s hospitalization are topicalized. The main aim of the paper is to problematize and analytically consider the role and purpose of play and toys in hospital conditions, in line with the relevant theoretical and empirical findings, and the measures of educational and health policy. We started from the assumption that the results of the research on the importance of play and toys during the child's hospitalization are not harmonized with educational and healthcare policy measures, neither at internationalnor at national level. The method of theoretical analysis and technique of content analysis were used. Two research instruments – content analysis matrices – were created. The basic units of analysis in the selected works (goal, sample, design and research results) and legislative and strategic documents (measures and understandings about play and toys) were analyzed using inductive coding, with respect to the defined research tasks. 24 scientific papers and 12 documents regarding educational and healthcare policies were included in the analysis. The results of the research indicate that play and toys during a child's hospitalization are primarily viewed as a health resource for overcoming and mitigating the negative psychosocial effects of the illness, while their role as a significant educational resource is secondary. In the corpus of analyzed documents of educational and healthcare policies, play is primarily understood as the child's right, need and important health resource. The need to create strategic documents and improve the existing legislation as a measure of public, i.e. societal support to play and its educational values during a child's hospitalization is recognized.

For the successful creation of educational work in kindergarten, it is essential that the preschool teacher starts with the children in the group, their authenticity, individualities and peculiarities. When appreciating childrenʼs authenticities and individualities, the basic assumption is that the preschool teacher recognizes the specificities of children and notices the differences among them, i.e. the peculiarities and possibilities of each child. This enables the preschool teacher to support the development of each child in the best possible way while observing the principle of individualization. Students have more modest experience related to the real kindergarten context, the educational work with children, and the differences between them. Therefore, the aim of our empirical quantitative study was to determine in more detail the perception students enrolled in a preschool teacher education study program have of the differences among children of preschool age. The online study was carried out in the academic year 2022/2023 on a sample of 105 students from the Faculty of Pedagogy of the University of Primorska, using an independently created survey with a five-point Likert-type scale of appropriate reliability. The obtained results indicate that students perceive the existence of differences among children related to all aspects of development.

Teacher cognition refers to the cognitive dimension of teaching that encompasses teachersʼ knowledge, beliefs, and thinking. This paper deals with the linguistic aspect of teacher cognition investigating the beliefs of early childhood care and education (ECEC) students in Croatia. The study aims to explore: their beliefs about the standard Croatian language (SCL), and their perception about the use of vernaculars versus the standard language in public communication. The data were collected through an online questionnaire administered to 69 students of ECEC at the University of Zagreb. The results showed that the participants generally agreed with commonly expressed beliefs that are sometimes build on the misconceptions about the nature and role of the SCL. However, their perception about the use of the SCL vs. vernaculars in public communication varied, with participants showing a lack of strongly formed opinions.

The research problem is the influence of video games on the speech development of preschool children. The research was based on the general assumption that video games influence the speech development of preschool children. It was also based on the special assumptions that the parents of preschool children estimate that video games have different effects on the speech development of their children depending on the sex and educational level of the parents. In order to determine this, a survey was conducted in April 2023 on a sample of 122 parents of preschool children at Olga Jovičić Rita preschool in Kraljevo. The data collected by Scaler – EP-IVG-SD-CHPA ( = .676) and processed by t-test and analysis of variance showed that there is no statistically significant difference in parents' assessments of the influence of video games on their children's speech development as regards the sex of the parents: t = 1.368; df = 120; p = .547, but that there is a statistically significant difference as regards parents’ educational level: F(2; 121) = 4.331; p = .015;  = .068. The results of the research are presented in the form of a conclusion and methodical implications are given, emphasizing the need to produce didactically designed video-games that will serve the purpose of speech development of preschool children. Possible implications for future research in this area are also discussed.

Bearing in mind the previous theoretical considerations related to the genre of childrenʼs stories, as well as the writers ofthe 20th century, the paper aims to study the poetic uniqueness of contemporary childrenʼs stories, using the examples of short prose by Igor Kolarov, Uroš Petrović and Dejan Aleksić. Conciseness, incompleteness, fragmentedness, enigma, wonder, and partnership with the recipient are the basic characteristics of contemporary children’s stories. The play in the work of these authors is present on several levels: in the form, structure, semantics of the story, as well as in the recipient’s experience. The contemporary story tries to influence the recipients directly, and the reader is often invited to participate in the self-referential and intertextual puzzle and to join the play of literary creativity. Therefore, it often requires an emotionally engaged, determined, intelligent, empathetic, adventurous and thoughtful reader. The stories of the abovementioned authors will be interpreted through semantic theory, reception theory and theories that study the phenomenon of play.

Owing to the abstraction of its content, on the one hand, and the nature of a child’s thinking, on the other, the development of mathematical concepts in preschool education is a considerable challenge for preschool teachers. Therefore, the process of preschool mathematics education should be organized in such a way that mathematical concepts are developed in the context which is close to the child and the objects of his/her immediate surroundings. With the aim of creating such learning environment, the authors of the present paper draw attention to a puppet as a pedagogical tool and point to its importance and possibilities of its use in developing early mathematical concepts. In that context, the authors call attention to the benefits of using a puppet in preschool education, and in preschool mathematics education in particular. By making use of concrete examples, the authors focus attention on the possibilities of utilizing a puppet in developing mathematical concepts in the content area of numbers, geometry, spatial relations, and measurement and measures.

In this paper, we tried to shed light on the problem of number from different angles. We first analyzed the key definitions of number which determined our understanding of number in the science of mathematics and mathematics teaching. It primarily concerns the understanding of number in the philosophy and mathematics of Ancient Greece, the Pythagoreans and Plato. Then, we pointed to a completely different understanding of both mathematics and the notion of number in the contemporary philosophy of mathematics. The emphasis was placed on the logicist definition of number. What suggests itself as a kind of conclusion is the existence of a priori structure which allows for different attitudes towards number, even in animals, or in children from the earliest age. This segment of analysis was supported by numerous psychological research publications. We also pointed to the significance of the notion of number in a broader, spiritual context of our culture.

The visual and musical arts are extremely important in the area of creativity, expressing emotions and experiencing the world around us. As artistic expressions, they are based on the individual’s inner experience, which is expressed through creativity. Both arts can be approached cross-curricularly, which can make activities even more interesting and educational, and motivate children to express themselves creatively. In a qualitative study conducted with children in the second age group in two kindergartens in Slovenian Istria, we investigated children’s response to cross-curricular activities in the fields of visual arts and music. We qualitatively examined the children’s artwork and analyzed how motivated the children were to express themselves in art with the chosen musical stimulation. We found that the children were highly motivated to work creatively, which was also evident in their artwork. The findings will contribute to the development of didactic approaches in the field of art in early childhood.

In modern practice of educational work in preschool institutions, portfolios are used as a way of monitoring and documenting childrenʼs development and progress. In the context of preschool education, portfolios have numerous functions and benefits. In addition to allowing educators to continuously monitor and document childrenʼs development and learning over an extended period of time, portfolios also facilitate the exchange of information about children's development with parents and other interested parties, as well as providing opportunities for critical reflection and evaluation. Unlike traditional portfolios that involve storing data in registers, boxes, or folders, electronic portfolios represent a collection of data in various formats, such as audio, video, and text. This paper highlights the importance, characteristics, and types of portfolios in preschool education, as well as the differences between traditional and electronic portfolios.

Research reports that there are certain signs of metacognitive processes at preschool age. Wellman (Wellman, 1985; after: Ковач-Церовић, 1998), for example, finds that children during the third year of life talk about some mental states in a way that indicates a real understanding of the basic nature of the psyche. They (Schneider & Lockl, 2002) link the development of metacognition to the development of declarative metamemory: childrenʼs understanding of terms such as know, think, remember, and forget. From the age of four, memory verbs can be used to describe exact mental states. The aim of my research is to examine the metacognitive abilities of preschool children. In order to throw more light on the general aim, it was expanded to include several specific aims: 1) identifying memory verbs which children use to describe their mental states when solving a puzzle; 2) identifying two groups of children (those who managed to solve the puzzle and those who did not) and 3) determining the differences between them. The research has the characteristics of both qualitative and quantitative research. A case study and the technique of systematic observation with associated instruments were used. The obtained results have important implications for educational practice.

The aim of the present paper is to determine the specific patterns of connection between childrenʼs participation in family routines – going shopping, spending free time and the family's social life, depending on the sex and age of preschool children. The sample consists of 334 parents of children attending kindergarten (94.3% mothers, 5.4% fathers, while in 0.3% of cases both parents provided answers). The data used in the research were collected using an online form – Google Forms, where a questionnaire was designed for the purposes of researching childrenʼs participation in family routines. The results indicate the existence of sex differences in childrenʼs participation in the shopping routines (x² = 22.32; p ≤ .001) and lack of significant statistical differences regarding free time and the social life of the family. In both sexes, a positive and statistically significant correlation is observed between the childʼs age and his/her participation in the family's social life (ρ = .43; p ≤ .005), as well as between the child's age and his/her participation in the shopping activities (ρ = .67; p ≤ .001), where in both cases the older age of the child is associated with higher degrees of participation. The perceived differences and the direction of connection among the examined variables point to significant practical implications in the field of preventive work. The research results, limitations, and implications for further research are discussed in the paper.
