Non-endodontic periapical radiopaque jaw lesions: A mini review
Authors: Zisis Vasileios , Papadopoulos Petros , Anastasiadou Pinelopi , Poulopoulos Athanasios , Andreadis Dimitrios
Published: March 2024

Endodontic practice may be affected by periapical radiopaque/ hyperdense lesions. Oral medicine specialists and endodontists may have trouble diagnosing and treating radiopaque lesions. Inflammatory, non-inflammatory, neoplastic, dysplastic, metastatic or metabolic bone changes may occur. With the increased use of cone-beam CT, a detailed review of radiopaque lesions may help clinicians differentiate these lesions. Differentiating inflammatory, non-inflammatory and neoplastic disorders simplifies diagnosis and helps choose the best treatment. Aim: The aim of this review was to investigate the periapical radiopaque/hyperdense lesions. An extensive review of the literature was carried through. The literature search was conducted using MEDLINE (National Library of Medicine)-PubMed, Web of Science and Google scholar without restrictions concerning the date of publication. The inclusion criterion was that the article should be written in English, whereas the exclusion criterion was the opposite. This literature review covers radiopaque/hyperdense lesion differential diagnoses, clinical, radiographic, histological, and management issues. The effectiveness of root canal therapy is measured by the absence of pain, the absence or reduction of periapical lesions, and the restoration of tooth function. In endodontic practice, the diagnosis of periapical lesions is difficult because many of these lesions can mimic endodontic lesions, even when derived from different sources. For the diagnosis of periapical lesions in this scenario, a comprehensive clinical examination, in conjunction with clinical and radiographic aspects of the disease, is essential. The oral medicine specialist and endodontist must know how to diagnose radiopaque periapical lesions. Knowing how to differentiate between inflammatory, non-inflammatory, neoplastic and metabolic lesions expedites diagnosis and ensures the selection of the appropriate treatment.
Comparative analysis of the remineralization potential of different active ingredients based toothpastes using SEM/EDX: An in vitro study
Authors: Kukey Pelin , Turkmen Cafer , Cimilli Zuhre
Published: March 2024

Background/Aim: The principal purpose of this study was to investigate the efficacy of different active ingredients to inhibit demineralization around the margins of cervical cavities in natural teeth by scanning electron microscopy and energy dispersive X-Ray elemantal analysis (SEM-EDX). Material and Methods: Thirty-two sound human molars were used. Box-shaped cavities were prepared along the cemento enamel junction (CEJ). The samples were were immersed in a demineralization solution (pH=1) maintained for 72 hours and randomly divided into 4 groups. Surfaces according to the groups were treated with potassium nitrate, arginine and calciumsodiumphosphosilicate containing remineralization agents for 14 days, respectively and the samples in control group were submitted to toothbrushing with deionized water. The samples were analyzed by using SEM-EDX analysis. Data was statistically analyzed using by one way ANOVA (analysis of variance) test and LSD (least significant difference) test for comparison between means at a significance level of 0.05. Results: SEM-EDX elemental mapping was used to evaluate the degradation from depth profiles of fluoride (F), Calcium (Ca), and phosphate (P) leaching. Micromorphological and elemental analyses were done using SEM and EDX. SEM EDX Analysis on enamel showed a significant difference between the groups except the control group (p<0.05). The dentine results showed significant differences between the control group and all other groups (p<0.05). Elemental analysis showed significant differences in Ca weight percentage among the first and second observation levels in all groups (p<0.05). Conclusions: In conclusion, all tested toothpastes showed some ability to resist demineralization at the margins. The groups except control group showed better outcomes compared with the other tested samples.

Influence of typing on the hours degree of independence of students in teaching mathematics
Authors: Mandić Aleksandra
Published: March 2024

In classical didactic theories as well as in the practice of the 20th century, different types of lessons were established that support the usual learning processes of younger schoolchildren. In the past decade, the transition of the education system and the reformation of the old school by introducing new work technologies, including the modernization of school textbooks, is transforming and merging various types of math classes. The process of learning is the process of changing individuals, under the influence of environmental conditions and activities. Significant roles in the process of constructing mathematical knowledge are teachers and textbooks that represent basic sources of information. This interdisciplinary paper deals with the role and significance of different didactic types of lessons through the prism of current problems in mathematics teaching. Using a single case study, teaching units in the first grade of primary school point out the qualitative difference between content intended for the hours of processing, practicing and determining mathematical knowledge. In addition to the lack of significance, which for early-school age have certain types of hours and different forms of transformation of mathematical contents, there is also a change in the natural temperature or learning speed, especially a harder measure. The annual and operational plans are not made in accordance with the nature of the subjects and the characteristics of the psychological development of the children, but are based on the subjective views of the authors of the textbooks who are very often in collision with the basic didactic principles of teaching. The mentioned factors lead to unnecessary pressure, student disability, problems with child restraint and parents' dissatisfaction with school.

Problem model of work in natural setup and society from the teacher perspective
Authors: Filipović Aleksandra
Published: March 2024

One of the ways that students are engaging thoughtlessly on the lessons, and the educational effects and quality of the acquired knowledge increase, is the application of the problem model of work (PMR). Considering that the contents of Nature and society are complex, interdisciplinary and allow for the application of various innovative models, we presented in our work the theoretical basics of the problematic model of work and the results of empirical research on the attitudes of teachers on the application of PMR in the teaching of Nature and Society. Our goal was to discover the problems of using PMR from the perspective of teachers and to obtain data relevant for improving the quality of organization and realization of PMR, as well as teaching of Nature and Society. The sample consisted of 62 teachers from different parts of Serbia, and the results showed that teachers, regardless of their years of work experience in education, the environment in which they work, the structure of the class and the class they are currently teaching, generally have a positive attitude towards applying the problem model of work in Continuing Nature and Society.

Authors: Pavlić Gordana
Published: March 2024

In this preparation for the analysis of the novel "Alice in Wonderland" in the fourth grade of primary school, the author shows one of the possible forms of realization of this type of class. The preparation for the class has all the necessary steps that made the analysing of the novel very successful. At the analysing classes of this novel, each step is well-planned and adapted to the psychophysical abilities of students of this age. Students learned about the novel by using modern methods and forms of work, as well as appropriate teaching AIDS. This contributed to understanding the novel in an interesting way, with aesthetic view of things, an optimistic view of the world and positive energy. Within this written preparation, the goals of time, educational, educational and functional tasks were emphasized in order to see what should be left to these two classes of novel analysis. The achievement of goals and tasks helped also preparatory tasks that were given to the students ten days before the work was completed. In the continuation of the preparation, in written form, and after the introduction, an emotional-intellectual admission of students for the time, emphasis and writing of the goal was made, an expressive reading of the passage "Down through the rabbit hole" from the novel. The second class of analaysis was carried out through group tasks, analysis of the results of the work, and then the final part of the time was highlighted and a homework assignment for the students was proposed. At the end of the paper, a conclusion was drawn up, followed by professional literature. Such a proces of analysis the novel "Alice in the Wonderland" meets the demands of a modern school that is being successfully realized, among other things, if the teacher is well "leading" students in the way of learning and experiencing the art world.

Classes are shifting to multimedia. The interactive "smart" board is just one of these tools -a media "changing the flow" of the classical teaching process. Through its utilisation (and also the utilisation of other modern media and content) the role of the teacher is also altered and it is increasingly morphing into the role of an organiser, a guide, albeit still being a control role which is irreplaceable. The possibilities of applying the "smart boards" are extensive, especially if teachers are willing to work on its development and application. Students are the ones who gain the most -they become more independent, confident, open, interested in working, advancing, competing… The paper offers an overview of possibilities offered by a practical application of the interactive "smart" board and the role of both the teacher and the students in such an environment.
Processing the story "Mačak Toša otišao u hajduke" using technique the reading with prediction
Authors: Tomić Dina
Published: March 2024

The tendency to modernize the teaching process of educational work, specifically in the teaching of literature, focuses as on a more creative approach in the study of literary-artistic texts. Teachers should encourage thinking about the text that is read, because it will allow the student to focus on important information, carefully think about what he has read, to understand and make it a part of his knowledge. Children need effective techniques and interesting activities that make it easier to understand the text and create the conditions for them, to read and write independently. Different techniques can be successfully achieved on the texts of a complex thematic, stylistic and aesthetic structure. Reading with prediction is a methodical strategy that awakens curiosity and encourages active reading for better understanding. In this paper is presented the possibility of applying reading with prediction, through the processing of the story "Mačak Toša otišao u hajduke", with pupils of third grade in elementary school.

Stimulation of language competence according to the Preschool Curriculum Framework: The example of development of morphological system
Authors: Jankovic Đorđe
Published: March 2024

The paper discusses ways in which the stimulation of language competence is aligned with the view of the child offered by the Preschool Curriculum Framework (rich in potential, creative, whole being, being of play...) and provides suggestions for harmonizing traditional teaching practices, manifested in domain directed activities, with the project approach. The potential for integrating language play with the contents of other sub-domains of speech development and other developmental domains is highlighted. Attention is directed to stimulating the development of the morphological system, in order to shed light on two aspects of it: ways to stimulate the acquisition of (1) morphological (inflectional) and morphophonological patterns and of (2) derivational patterns. It is found that the kindergarten teacher's preparation for such subject requires an awareness of the ways of uncovering the derivated words, ways of introducing patterns, ways of representing the meaning of derivated words or their morphemes, understanding the derivational meaning, the selection of derivational patterns and examples, and how they are extracted from dictionaries. It is concluded that a quality holistic approach to the child requires not only the application of general pedagogical principles, but also of the principles of the subject, as outlined.

The importance of thematic planning for the integrative access to teaching content in the first cycle primary education
Authors: Petrović Ivana
Published: March 2024

An integrative approach in teaching implies removal of time and content boundaries between teaching subjects and access to one topic from many different aspects. This way of teaching provides connection between different areas of knowledge. The first step toward this is thematic planning. We conducted a survey among 162 teachers from 16 elementary schools in Serbia. The aim of the research was to determine the teachers' attitudes towards integrative approach and thematic planning, to determine whether they use them in their work, in which extent and for what reasons. We also got an insight into the difficulties that teachers are facing with while planning their educational work. The results of the research confirmed hypotheses that teachers rarely apply an integrative approach in teaching, although they are familiar with its significance, while the application of thematic planning is at a satisfactory level. We came to the conclusion that the complexity of applying thematic planning and integrative approach as an imperative imposes the improvement of motivation and professional competence of teachers.
Application of phonomymics in teaching music culture in classroom teaching
Authors: Munćan Suzana
Published: March 2024

In the work with students of younger grades, more precisely combined - from the first to the fourth grade, the possibility of applying phonomimics in the teaching of music culture was examined. The paper is an attempt to go beyond the classical organization of teaching this subject. By applying phonomimics, as a methodological innovation, the vagueness of program contents was reduced, while the number of processing hours was reduced in favor of determining and practicing hours. The dynamism of the time is enhanced. Teacher creativity directly encourages students' motivation and independence. Functional learning is achieved by applying stimulating teaching tools for the class, didactic-methodical vertical and horizontal linking of the content of music culture programs and directing students to memorization through situations that are imposed on the senses. In the final part of the class, with an interactive five-minute check, the lecturer gains insight into the results of the work he achieved in that class. That is, whether learning through phonomimics has an effect on shaping different segments of teaching and learning. Also, our intention with this paper is to inform teachers about the application of phonomics in younger grades and encourage them to search for adequate methodological solutions in the teaching of music culture.
Computational estimation: Theoretical and methodological foundations
Authors: Ilić Svetlana
Published: March 2024

The practical significance of computational estimation is noticeable in everyday life, but the place and role of estimation within mathematical abilities is also important. The paper presents the theoretical and methodological foundations of the concept of computational estimation, the development of estimation skills, and it gives a systematic overview of computational estimation strategies. Computational estimation, due to its nature, has not been much examined and a small number of papers that have tested the effectiveness of the teaching instruction have been observed. However, the results so far suggest that it is possible to develop the estimation ability in both children and adults, and that this contributes to mathematical flexibility, better achievement and attitudes towards mathematics. The place of estimation in the curricula was examined and methodical recommendations for teaching were given. Computational estimation should be integrated into as many mathematics teaching content as possible, and new research suggests that estimation skills should be developed from preschool age.
Controversial discussion for improvement geography teaching
Authors: Lazić Božidar
Published: March 2024

Beside earning factually and logical knowledge, insight into casual-ensuing relations between objects and phenomenons, it is necessary that pupils develop some skills during pedagogical-educational process. Children's cooperation in dealing with group tasks is very important from school aspects. Educational aspect means that they are taught by their coevals at the same time as they transfer knowledge to them, which is required for achieving goals. On the other hand, pedagogical part consists of earning motivation, sense of belonging to a group, sense of own significance and contribution to group success, but it also includes obstacles which pupils must manage. All that have been mentioned belongs to special concept in schooling, named controversial discussion. The name itself indicates the basic characteristics of concept - analysis certain controversial topic (actual and traditional) on classes, defense and criticism of standpoint. The best results using this kind of work are achieved by rotation of roles, more precisely in the end of first debate pupils that defended one standpoint, the second part of debate start to support standpoint they criticized before. Debate must be based on scientific arguments and acquired experiences, without one-sided expression.

Authors: Brčkalo Branka
Published: March 2024

The riddle as a valuable content of oral folk literature is insufficiently represented in the current curriculum and in teaching for the younger grades of primary school in the Republic of Srpska. It is assumed that the riddle, as a very old folklore genre, had a more pedagogical than entertaining character in the past. The paper discusses the possibility of using the riddle as a motivational tool and as a teaching content in the teaching of the Serbian language. In both cases, it can be in the function of speech development, it can complete the experience of students, stimulate thought activity, research spirit, critical thinking, which we will try to show with this paper.

Authors: Anđelković Goran
Published: March 2024

This article researched design practice and construction activity of the project studio "Invest-projekt" from Belgrade. In the ten-year activity period (1952-1963), this small project studio, with a small number of young, enthusiastic and talented architects, gave birth to high-quality, recognizable and author's architecture, and finally a well-designed and built space during the 1950s. On the basis of available knowledge, drawn from direct testimony, available sources from professional periodicals and partially preserved project documentation, the first step was taken towards evaluating his contribution to the development of Belgrade and Serbian architecture in the second half of the 20th century, and determining the exact number of designed and constructed buildings in the area of the city of Belgrade. Special attention was paid to elucidating the working methods of this studio, especially regarding to received typologically diverse investments, then logistical support to other architects, such as Branko Pešić and Miroslav Mirko Jovanović, and finally participation in architectural competitions. The built building fund, consisting of school, residential and administrative buildings, represents a valuable and precious material legacy of this studio, which was worked on by at most two women architects - Danica Dana Milosavljević and Zagorka Lula Mešulam.
The possibilities and benefits of volunteering within protected areas in Serbia
Authors: Jelić Ivana , Antonijević Snežana
Published: March 2024

Improving the management of protected areas through the implementation of planned management measures is of key importance for the adequate protection and conservation of protected areas. One of the many opportunities that can be undertaken in this sense is volunteering, which is a basic and key means of active participation of citizens in solving the issues of wider community. Volunteering contributes to the creation of a stable and, for the individual, attractive social community that offers the possibility of action in the field of nature protection and management of protected areas. The aim of this paper is to analyze the results achieved through various volunteering activities within protected areas, as models of good practice, as well as to provide an overview of the possibilities for increasing the capacity of managers in human and material resources in the process of managing protected areas, which includes the process of involving volunteers. The results of various projects show that volunteers can contribute to the management's activities in different ways, and primarily by performing specific tasks for which the managers lack enough capacity. Moreover, volunteering within protected areas achieves a higher level of awareness among individuals, especially young people, about growing problems in the field of nature protection, challenges in managing protected areas, but also about the way each individual can contribute to the conservation of nature for future generations.

Drivers of Dollar Share in Foreign Exchange Reserves
Authors: Goldberg Linda S. , Hannaoui Oliver
Published: March 2024

The share of U.S. dollar assets in the official foreign exchange reserve portfolios of central banks is sometimes taken as an indicator of dollar status. We show that the observed decline in the aggregate share of U.S. dollar assets does not stem from a systematic shift in currency preferences away from holding dollar assets. Instead, a small group of countries with large foreign exchange reserve balances drive the dollar share decline observed in aggregate statistics. This arises either due to countries conducting monetary policy vis-à-vis the euro or due to preference shifts away from dollars. Regression analysis shows that interest rate differentials between traditional and nontraditional reserve currencies can tilt portfolio composition, particularly in relation to the scale of investment tranches within overall central bank portfolios. Geopolitical distance from the United States and financial sanctions are associated with lower U.S. dollar shares, especially if the primary foreign currency liquidity needs of the central bank are already satisfied.

The purpose of this Article is to determine whether the method of accounting for profit tax in Section 29 of IFRS for SMEs is appropriate.  This objective was raised in the context of the international debate on this subject, since it is considered that it is costly for such companies to implement them.  The theories analyzed deal with the usefulness of financial information and deferred tax.  The method used was quantitative.  Some statistical tools were used that helped to determine the distribution of the data and to obtain the equality of means.  These tools were that of Shapiro Wilk and the W of Wilcoxon. The results found denote that in the small companies of Ecuador the change of regulations of the NEC Equatorian Accounting Standards to IFRS International Financial Reporting Standards are beneficial, therefore, it would be entering within the logic of the tax effect method as a profit tax registration model.

Uncertain economic situation of developing countries like Pakistan is posing threat to marginalized societies and lives in rural areas. Microcredit is considered as most efficient tool in mitigating the vulnerable condition i.e. either due natural calamities or economic policies. This study was fact finder is checking the impact and highlighting the problems associated with microfinancing. For the purpose cross-sectional study was carried out in three randomly selected districts of Punjab province. From each district 200 beneficiaries of microfinancing were selected using lists provided by the regional offices of MFIs. Data obtained through interview schedule from sample of 600 was analyzed using SPSS. Results revealed that respondents received microcredit both for social as well as agricultural purposes. Results showed that percentage share of farm income have been increased after receiving of microcredit. There is a relatively lower impact of microcredit on some indicators such as access to education and health facilities, contribution to family income, and household income level. For tackling the problems like in-time disbursement and repayment, monitoring, business advisory to front man and regular meetings with borrowers can make difference. However, introducing reward system for repayment can be effective.

Published: March 2024

The magnitude of the earthquake load received by the structure is influenced by the peak acceleration parameters of the bedrock for a period of 0.2 seconds (Ss) and a period of 1 second (S1). This research measures the effect of increasing Ss by 0.1g on 10 and 30 storey building structures in DIY. The parameters measured include frequency, story drift, p-delta influence, stiffness and stability index in 7 sub-districts in DIY using equivalent static earthquake analysis and response spectrum variance analysis. The frequency of 10 and 30 storey buildings in the first 3 modes is less than 1 Hz. This frequency is below the peak acceleration frequency of the DIY earthquake which was measured in the range of 1.25 Hz to 7.14 Hz in the 7 sub-districts studied. The frequency of earthquake vibrations in DIY is more dangerous for low to medium storey buildings or buildings with a period (T) of less than 0.8 seconds. An increase in Ss of 0.1g in a 10-story building resulted in the earthquake force distribution increasing by 3.99% in the x and y directions, story drift increasing by 4.12% in the x and y directions, p-delta increasing by 0.46% in the x and 0.28% in y direction, rigid structure, each floor is a swaying portal. Meanwhile, in a 30-story building, the earthquake force distribution increased by 6.24% in the x and y directions, story drift increased by 6.27% in the x direction and 5.31% in the y direction, p-delta increased by 0.15% in the x direction and 0.55% in y direction, rigid structure, each floor is a swaying portal..

The aim of this research was to study the productive potential and evaluate the fiber properties of the new Selena cotton variety. The variety was studied in competition variety trials conducted in 2017-2022 in the experimental field of the Field Crops Institute in the town of Chirpan. In the IASAS system the variety was tested in 2021-2022. It was approved as a new cotton variety in 2023. Selena variety was created by remote hybridization from the crossing of the allotetraploid Gossypium thurberi Tod. × Gossypium raimondii Ulbr. with Dorina variety and subsequent backcrossing with Darmi variety. Selena variety is an early and productive new cotton variety with improved fiber quality. The vegetation period was 106-111 days. In seed cotton yield of 1663 kg/ha, on average for 6 years, it surpassed the standard cultivar Chirpan-539 by 12.3%. According to the IASAS data, in seed cotton yield of 2163 kg/ha it exceeded the two standard cultivars, Chirpan-539 - by 2.2%, Avangard-264 - by 1.3%, the average standard (average of the two standards) - by 1.8%. In lint yield of 95.5 kg/ha Selena variety was equal to Avangard-264, surpassed Chirpan-539 by 2.9% and respectively the average standard - by 1.4%. Selena variety had a number of valuable technological fiber qualities and in some indicators surpassed both standard cultivars. Compared to the two standard cultivars it had better Spinning Consistency Index (SCI), greater Upper Half Mean Length and fiber strength, lower micronaire, better spectroscopy with RD difference reflection than Chirpan-539, less yellowness than Avangard-264 and better fiber whiteness. Selena variety combines better productivity with better technological fiber qualities than the standard cultivars, which defines it as a new achievement in the selection of cotton in our country.
