Didactic transposition arithmetic content in textbooks of mathematics
Authors: Šćepanović Rada
Published: March 2024

Didactic transposition of the arithmetic content in the starting teaching mathematics is only possible if you keep in mind the student of a particular age, to whom the content of the natural numbers is intended, his level of logical thinking, previous knowledge and experience. Undoubtedly, these demands need to be met in home math textbook as well ,i.e., to allow the adoption of relevant knowledge of arithmetic and to participate in the development of thinking and other cognitive abilities of students. Therefore, this paper first describes significant psychological basis, and then the specific details in the transposition of the initial mathematical content. In the end, for the purpose of completing and more impartial studies of selected problems of research, the arithmetic facilities have been analyzed in the textbooks of mathematics from first to third grades of elementary school education system of Montenegro, which was carried out in 2014. Didactic actions of the adoption of natural numbers in the textbooks are viewed through a global research access to research textbook, which aim is to establish the contents of textbooks and methodical psychological characteristics. The results that we got shows that the arithmetic support facilities are exposed by logical order but there are irregularities in textbooks at present : scientific, methodological ,art-graphic and language - stylish approach. The dominant form of activation of the students is memorizing The teaching facilities of the natural numbers are not connected with other subjects and examples of real environments. The findings indicate that the listed disadvantages can be overcome: by improving the quality of the content of the existing textbooks - structuring teaching units; by implementing new content into an existing curriculum home math; new approaches of teachers in the use of textbooks.
Conditions of length measurement using lenyor for pupils 2nd and 4th graders elementary schools
Authors: Antić Milica
Published: March 2024

The aim of the paper was to determine how successfully pupils of the 2nd and 4th grades mastered the term length measurement using the measuring tool - ruler. We focused on the following components: the starting point - zero-point, additivity, division, linking of measuring units and distance accumulation, and based on them, devised assignments for pupils. The sample of the research consists of 145 pupils, of which 72 are pupils of the 2nd grade and 73 pupils of the 4th grade. A descriptive method is applied. The results of the research and pupil responses are in line with other research and indicate that the pupils' understanding of the measurement process is incomplete and very poor, as well as that the understanding of the scale measurement representation is lacking. Recommendations for teaching in the form of pedagogical implications are that pupils should first meet with non-standard units of measurement, followed by a standard ones, and establish a clear connection with the construction of the measurement scale. It is necessary to focus on the development of the basic components of the concept of length measurements using the measuring tool while working with pupils, as well as the designing of activities such as: self-made rulers, measure with the broken rulers, the use of unnumbered scales etc., which would prevent the occurrence of common pupil mistakes.
Isometric transformations in the development of spatial reasoning
Authors: Šćepanović Rada
Published: March 2024

Translating, rotation and symmetry, i.e. isometric mapping, and their compositions are transformations that do not distort the shape and size. The aim of this paper is to demonstrate that various examples of isometric transformations encourage the early development of students' spatial reasoning. The basic starting points of this work are: (1) the connection between school geometry and spatial reasoning, and (2) the characteristics of spatial reasoning in children and instructions in encouraging the development of their spatial abilities. The results that have been obtained by the method of theoretical analysis show more approaches that encourage the development of spatial reasoning skills in children, from conversations with teachers and peers, game matching, drawing, and reconstruction of three-dimensional objects to the use of software packages and touch technologies. In isometric tasks, students first use visualization, to evaluate which forms are matched, compare forms, mentally and physically rotate the shapes received and recognize shapes from different perspectives. It has been concluded that there is clear evidence that even the youngest students, if offered high quality opportunities, can be engaged in challenging activities of isometric transformations. Therefore, transformations can be introduced to primary school students, not directly with explicit definition, but in an informal way, choosing an appropriate context so that geometric activities for students have meanings. In order for students to gain understanding and insight into these fundamentally difficult aspects of isometric transformations, they must be rooted in the experiences that students have on a daily basis, as well as in the tasks set by the teacher. Conclusions point out to the importance of designing isometric tasks and teacher mediation, especially with regard to the use of such software, as a catalyst for the development of culture, in a classroom, where teachers and students expand their beliefs about learning and understanding isometrics.

Relativization of conflicts in the area of UNESCO World Heritage Site: The case of Studenica Monastery, Serbia
Authors: Dobričić Milica
Published: March 2024

Conflicts in space encountered by participants in the development of spatial plans for special purpose areas of cultural or natural assets are numerous, and the most significant are between protection and development. The relativization of the conflict implies the harmonization, neutralization or minimization of mutually opposing interests and goals in that area. This paper investigates conflicts in the area of the Studenica monastery, a cultural property inscribed on the UNESCO World Heritage List in 1986, as well as in the area of the cultural landscape that surrounds it. In this particular case, conflicts were identified between the protection of cultural heritage on the one hand and the development of transport infrastructure, water management and the exploitation of mineral resources on the other. The task of spatial planning, as carried out for special purpose areas, is the relativization of conflicting interests in space. This paper shows that in relation to conflicting interests in the area of a world heritage site, not everything is contingent on the creation of spatial plans of special purpose areas, but rather on their realization, monitoring and evaluation, as well as on the corresponding capacities in general. The aim of the research presented in this paper is to point out the importance of spatial planning in the relativization of conflicting interests and goals using the example of the world heritage site planning of the Studenica monastery.
A study on the influence of austenitization temperature on the mechanical, thermal, and structural properties of 51CrV4 steel

Published: March 2024

In this paper, emphasis is placed on studying the influence of quenching temperature (austenitization) on the mechanical, thermal, and structural properties of 51CrV4 chrome-vanadium steel. Generally, 51CrV4 steel is often categorized as spring steel; however, in recent years, it has been increasingly used in the production of different types of tools, so it can also be categorized as tool steel. To obtain better-quality tools, this steel is subjected to various types of heat treatment, which usually include normalizing, quenching, and medium-temperature tempering. In this investigation, the samples were austenitized at different temperatures, ranging from 780 °C to 920 °C, and subsequently quenched in oil. After quenching, the samples were tempered at a temperature of 350 °C for 2 hours. The goal was to monitor the influence of austenitizing temperature on hardness, thermal conductivity, and microstructure by subjecting the samples to characterization after the applied heat treatment. The results showed that with an increase in the austenitization temperature, the hardness values gradually increase, reach a maximum, and then decrease, regardless of the type of heat treatment. On the other hand, thermal conductivity values show the opposite trend. After the characterization, it was concluded that by choosing a low austenitization temperature (770 °C), samples would be cooled from the two-phase region (a+g), which produces lower hardness values. However, choosing a high austenitization temperature (920 °C) would lead to austenite grain growth and surface decarburization, again lowering hardness values.

Nonlinear Firm Dynamics
Authors: Melcangi Davide , Sarpietro Silvia
Published: March 2024

This paper presents empirical evidence on the nature of idiosyncratic shocks to firms and discusses its role for firm behavior and aggregate fluctuations. We document that firm-level sales and productivity are hit by heavy-tailed shocks and follow a nonlinear stochastic process, thus departing from the canonical linear. We estimate a state-of-the-art model to flexibly capture the rich dynamics uncovered in the data and characterize the drivers of nonlinear persistence and non-Gaussian shocks. We show that these features are crucial to get empirically plausible volatility and persistence of micro-originated (granular) aggregate fluctuations.

Public R&D Expenditure Efficiency and Knowledge Creation in CEE Region
Authors: Greganić Dalibor
Published: March 2024

In this paper we use the data envelopment analysis (DEA) to analyze the efficiency of public expenditure on R&D in Central and Eastern European countries (CEE), using knowledge creation and knowledge diffusion as key output indicators. Our results show that most CEE countries do not use public R&D resources efficiently and that the current level of expenditure should generate much better results on the Global Innovation Index scale. Thus, we believe that instead of increasing the level of public expenditure on R&D, the CEE countries need to increase efficiency first. In order to do so, these countries should continue to improve their institutional framework in terms of government effectiveness, business climate and suppression of corruption. The increase in R&D efficiency is of great importance for the CEE countries as they look for new knowledge-based growth models that are more challenging for policy makers than pre-crisis models, which were based on physical capital accumulation and adoption of technologies from abroad.

Sorghum bicolor and Trifolium repens extracts as plant coagulants can be used for wastewater treatment instead of chemical coagulants. This study investigates the effects of pH and coagulant dose on COD and turbidity reduction by natural coagulants. In the optimum treatment conditions of 100 mg/L coagulant dose and pH 7, high turbidity (81.34%), and COD reduction (62%) (compared with alum and FeCl3) were obtained. The percentage of COD reduction is higher in Trifolium repens than the other plant coagulant, and the percentage of turbidity reduction is higher in Sorghum bicolor. FT-IR spectra were performed on the plant extracts to identify the existing factors in active extracts. Also, outlet COD and turbidity values can be predicted and calculated according to computational equation in similar treatment systems. It should be mentioned that the only applied solvent for extracting the natural coagulant seeds was distilled water, and none of the other solvents such as NaCl and NaOH were used. According to the results, the characteristics of the treated effluents by the plant extracts make them appropriate alternatives for textile wastewater treatment.

Authors: Kumar Som , Singh Karamjit , Brar B.S. , Kumar Santosh
Published: March 2024

Abrasive flow machining (AFM) is a non-conventional machining method used for the fine finishing of complex external/internal surfaces of metallic parts. Generally, this process has a low material removal rate (MRR) and is a more time-consuming process. So, to overcome this problem, various researchers employed hybridization of the abrasive flow machining process (AFM) with a distinct nontraditional machining process. Hence, this paper aims to provide a detailed review of the electro-chemical assisted AFM (ECA2FM) process, which is a combination of electrochemical machining and abrasive flow process. Then, the effect of processing parameters such as grit size and type, the total number of cycles, current, voltage, abrasive type and size, extrusion pressure, design of workpiece holding device and proper tooling on the material abrasion and surface finishing is summarized. Thereafter the Progressive outlook on the integration of electrochemical AFM with magnetic energy is given. Finally, the emerging applications of the electrochemical AFM process are discussed.

Authors: Bustos Moreno Yolanda
Published: March 2024

La nueva política comunitaria de impulso a la movilidad urbana inteligente y automatizada, particularmente, la implementación del U-Space está convirtiéndose en una realidad merced a los avances de tecnologías emergentes como la inteligencia artificial. Estos novedosos medios de transporte requieren probar sus funcionalidades a fin de garantizar que alcanzan los suficientes estándares de seguridad a través de los “espacios controlados de pruebas”, conocidos como regulatory sandboxes. Esto implica integrar adecuadamente los dictados de la futura Ley de Movilidad Sostenible con la regulación ya vigente aplicable a los marcos normativos sectoriales sobre transporte. El éxito del despegue de los regulatory sandboxes dependerá de que vengan sustentados bajo la premisa de un régimen de responsabilidad civil claramente delimitado, objeto principal de este estudio en lo referente al espacio aéreo.
