Authors: Kotova I. A. 
Published: July 2022

Preparing young people for the future of work is one of the tasks of paramount importance. Based on the focus of modern education on the formation, in particular, of general competencies, the features of the interaction of the teacher with students in mastering the educational material are pointed out. The solution to the problem of the formation of general competencies of students from the standpoint of the eﬀectiveness of this process is possible when the teacher uses methods for organizing the activities of students that meet certain requirements (criteria for enriching subjective experience).A theoretical analysis of the scientiﬁc, pedagogical and methodological literature was carried out, a generalization was made and the systematization of the studied material was carried out, which made it possible to identify the conditions for the successful organization of students’ activities and indicators of the formation of general competencies of future specialists. In connection with the need to develop methodological support for the organization of students’ activities from the standpoint of developing general competencies, a procedure for improving the method of organizing students’ activities chosen for a speciﬁc learning situation is presented, which allows the teacher to model new techniques based on a speciﬁc goal. On the example of studying educational mathematical problems, it is shown how the procedure for improving the technique chosen by the teacher is carried out. The results obtained can be useful not only for teachers of mathematics, but also for teachers of other academic disciplines, as well as for creating a lecture course for the advanced training program for educators.

Published: July 2022

The development of an ultrasonic ﬂ aw detector receiving unit for rail monitoring includes theoretical and practical studies. Special attention is paid to the experimental determination of the characteristics of the ultrasonic piezoelectric sensor and the description of the receiving-amplifying path. A mock-up sample of an ultrasonic ﬂ aw detector allows checking rails for defects and gives a tangible gain in dimensions compared to bulky analogues.The theoretical methods used were based on the principles of electrical engineering, electronic engineering, graphical analysis and the theory of automatic control.Experimental studies of the piezoelectric sensor allowed us to determine its main resonant frequency. The correct choice of parameters of the ampliﬁer unit ensured accurate and reliable operation of the device. Practical tests of the ﬂ aw detector using a special buﬀer sample of the rail made it possible to adjust its sensitivityThe input ampliﬁer of the microvoltmeter V3-40 is taken as the basis of the receiving and amplifying path of the ﬂ aw detector. The device includes the possibility of its use in conjunction with the converter. The structural diagram of the ﬂ aw detector is presented. The electrical circuit of the input divider with the selection of the necessary resistances and the electrical circuit of the eﬀective value meter with a description of all its elements are described.Operating modes and electronic circuits are selected according to reference data, taking into account their high reliability of operation. The use of analog integrated circuits in the circuit solution made it possible to increase the reliability and accuracy of the ﬂ aw detector device, simplify its adjustment, reduce zero drift and improve the quality of the output signal.

Implementation of the spatial voltage vector modulation algorithm using an artificial neural network
Authors: Chol Kim Gum , Song Kim Gum 
Published: July 2022

An algorithm for space vector pulse width modulation (SVPWM) based on an artiﬁcial neural network is proposed.In calculating the action time of the voltage vectors according to the traditional SVPWM algorithm, the values of the relative phase angle on the sectors are used as variables, which causes diﬃculties in their calculation.To overcome these shortcomings, mathematical models have been compiled that determine the opening time of the power element by the absolute phase angle on the inverter converter. Since mathematical models have different types of calculation formulas for sectors and it is impossible to express them in an unambiguous formula, to eliminate these diﬃculties, a function was built using an artiﬁcial neural network, with which you can generally determine the opening time of a power element in phases A, B and C.Regardless of the sectors, the SVPWM algorithm sets the opening time of the power element according to the phase angle θ on the inverter converter.The generalized ability of the artiﬁcial neural network and its accuracy, as well as the simulation operation time in the MATLAB environment, were tested.The proposed method makes it possible to achieve high speed control accuracy and signiﬁcantly reduce the operation time.When controlling the traction drive of an electric rolling stock with an asynchronous traction motor, it is possible to reduce the regulation period, as a result, the traction capacity of electric locomotives and metro electric trains with vector control or with direct torque control increases by about 1.1–1.2 times.

Published: July 2022

The main task of the transport system is the most complete satisfaction of the needs of business entities and the population in transportation, reducing the time of delivery of goods and transportation of passengers on the basis of a qualitative increase in the capacity of the entire transport system. This problem is solved with the help of computer technology and new information technologies in transport management systems. The most demanded is the database technology implemented in modern automated transport management information systems.Given the exponential growth in the volume of databases used, strict time limits for real-time management decisions in transport management systems, the task of minimizing the time to execute information queries in the database is of particular relevance.The execution time of information requests is influenced by the methods of physical storage of databases. To solve the problem of minimizing the execution time of information requests, it is necessary to determine the physical parameters that affect the efficiency of database processing.An external memory simulation model is described for optimizing the physical parameters of database organization, based on the exchange procedures implemented in modern database management systems between external and operational memory upon information requests. As a key optimization parameter, a memory block reservation factor is substantiated, which allows minimizing the number of slow accesses to external memory.The rationality and adequacy of the proposed model in the process of research is confirmed by the results of simulation modeling.

Published: July 2022

Over the past two years, due to the spread of the epidemic and the restrictions imposed, state borders have been closed, restrictions on the movement of people and goods have been established, supply chains have been disrupted and, as a result, consumer demand and purchasing power have decreased. These events had a negative impact on the revenues of operator companies. Transportation of goods is carried out by diﬀerent modes of transport. The choice of transport depends on many factors: the volume of cargo transported, the location of enterprises of producers and consumers, the degree of development of the transport infrastructure.At present, the task of reducing the transport component in the price of goods and, accordingly, the costs of operating companies of railway rolling stock during the transportation of goods is becoming urgent. This can be achieved by outsourcing some of the work performed by rolling stock operating companies.The conditions for the termination of work by the rolling stock operator are considered. A tool for analysis is presented, an assessment of the eﬀectiveness of outsourcing is made. The use of outsourcing will allow railway rolling stock operators to reduce costs for non-core activities, to focus on those processes that directly bring proﬁt.

Authors: Sabroso Leomar M. , Tamayo Adrian M. 
Published: July 2022

<p>The Philippine coffee industry is dominated by small-scaled farm households. This study was conducted to measure the technical efficiency of coffee production in Davao City using Data Envelopment Analysis. The study also determined the factors that contribute to the technical efficiency of coffee farms using Logistic Regression. Among the 166 respondents obtained, the study revealed that only 11 DMUs are technically efficient operating under constant return to scale while 154 and 1 were technically inefficient operating under increasing return to scale and decreasing return to scale, respectively. This means that input such as farm size, labor, number of coffee trees, age of coffee trees, fertilizers and pesticides has to be adjusted in order to reach the frontier to be technically efficient DMUs in which coffee farms are the potential to increase production if provided with appropriate support. Furthermore, to achieve bias-corrected DEA technical efficiency scores, Bootstrapping was done and later used for regression. Meanwhile, the logistic regression results revealed that there were significant relationships between technical efficiency and socioeconomic such as Age of Household Head, Sex, Access to Credit, Cropping System, Technology, and Coffee Variety. However, the logistic regression also revealed the factors that have no statistically significant relationship in the variables such as Education, Farm Experiences, Household Size, Extension Services, and Off-farm Activities.</p><p> </p><p><strong>JEL</strong>: L60; L66; O13</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0929/a.php" alt="Hit counter" /></p>

MICRO-COUNSELING SKILLS MASTERY OF GUIDANCE COUNSELORS AT JUNIOR HIGH SCHOOLS
Authors: Saputro Henri , Wangid Muhammad Nur 
Published: July 2022

The purpose of this study was to determine how far the micro-counseling skills mastered by Guidance Counselors (counselor) at the Junior High School (SMP) in Kulon Progo Regency. The subject of the study were guidance counselors/teachers at the Junior High Schools in Kulon Progo Regency with a proportional sample of 33 teachers. Research data were collected using a questionnaire instrument and analyzed using quantitative and qualitative descriptive techniques. The results of the study show: 1) All guidance counselors believe that the use of counseling skills can improve the quality of counseling services, but only the majority of guidance counselors use these skills. The micro counseling skills used by most of the Kulon Progo guidance counselors are attention, opening, acceptance, direction, strengthening, advice, summary, and termination. 2) A small number of guidance counselors admitted that they had never received micro-counseling skills material, either when they were still students in college or when they had entered as practitioners or guidance counselors. Suggestion from this research is that guidance counselors need to take part in training to increase their capacity for mastering micro-counseling skills. The training can be in the form of role-playing with colleagues or practice handling cases directly with the assistance of a competent supervisor. Professional organizations, universities, and schools need to provide support to guidance counselors in efforts to develop and improve the competence of micro-counseling skills.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0765/a.php" alt="Hit counter" /></p>

Published: July 2022

This article examines the perceptions of preschool teachers in reference to their role in the school context. In recent years teachers have been obliged to take on additional roles. Except for solving problems related to the pedagogical process, they should be able to solve general issues related to the operation of the school unit. The qualitative method was followed for the design of the research tool and its analysis. The research involved 47 preschool teachers of public kindergartens in Western Greece. In order to study the perceptions of preschool teachers about their role in the school context we, used an open-ended question. For greater validity of their answers, preschool teachers are asked to answer in two questions. In the first question, the participants describe their role using literal language while in the second question the participants describe their role using metaphors-metaphorical images. The results of the study as far as the first question is concerned, which regarded preschool teachers’ perception of the use of literal language, recorded sixteen (16) categories. The second question, regarding the perceptions of preschool teachers about the use of metaphors-metaphorical images resulted in eight (8) categories. The NVivo-8 qualitative analysis software was utilized for data analysis.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0951/a.php" alt="Hit counter" /></p>
