Contradictions of the mesoeconomic level

E.N. Bolkhovitina — 2025-06-27

The authors consider the contradictions of the mesoeconomic level on the example of the innovation sphere. A contradiction is understood as a state (temporary, but critically significant) of incompatibility of individual entities (attributes, properties, qualities, parameters, and functionality of certain elements of the system — subsystems, actors), which objectively arise during the development of systems (subsystems, actors). The method of comparison and juxtaposition allowed us to interpret the "barriers" of the innovation sphere as "contradictions".

S.V. Bespalyy — 2025-06-27

The article considers the problem of integrating sustainable development principles into higher education through professional training of teachers. Based on the analysis of international experience, key approaches to the development of educational courses on education for sustainable development are analyzed. The main components of effective teacher training are defined: substantive (Agenda 2030, SDGs), theoretical and methodological (active and transformational pedagogical approaches). The methodological basis of the study consisted of: a system analysis of scientific publications and reports of international organizations (UNESCO, SDSN), a comparative study of successful cases of ESD integration in universities in Europe and Central Asia, as well as a content analysis of the curricula of Kazakhstani universities. It is shown that the proposed teacher training course should include three face-to-face sessions devoted to: 1) analysis of sustainable development concepts, 2) formation of professional competencies in the field of ESD, 3) design of sustainable educational scenarios. The need to combine theoretical classes with practical work on modernization of curricula is revealed. It has been established that the key conditions for the successful implementation of the course are: taking into account the national educational standards of Kazakhstan, developing a system for monitoring the effectiveness of training, and creating institutional mechanisms to support teachers. Particular attention is paid to limitations, including the need to move from declarative changes to real transformation of educational practice. The results of the study are of practical importance for the development of a national program for advanced training of teachers in the field of ESD, contributing to the implementation of the SDGs in Kazakhstani universities.

Cao Hao Cao Hao — 2025-06-27

In table tennis scenarios, there are many difficulties in picking up table tennis balls after training and matches. The traditional way of picking up table tennis balls by manpower is extremely inefficient, especially when the balls are scattered all over the field or even rolled to the narrow area, the manpower picking up not only consumes a lot of time and energy, but also easy to lead to the staff's discomfort due to frequent bending down. With the rapid development of science and technology, the application of robotics in various fields is becoming more and more extensive, and the research and development of table tennis ball pick-up robot has become a key direction to solve the problem. The microcontroller-based table tennis ball pickup robot designed in this paper takes STM32F103C8T6 microcontroller as the core controller, and integrates servo motors, infrared sensors, ultrasonic sensors and collection devices and other hardware modules. The robot can quickly and accurately identify the environment of the arena, and efficiently pick up and place the table tennis balls through the spiral pickup device and collection device. The design is highly flexible and stable, and can quickly and accurately locate the table tennis balls in small training venues, which greatly enhances the efficiency of picking up table tennis balls and improves the training experience of the athletes. The successful implementation of this design will significantly improve the efficiency of table tennis training and significantly reduce manpower investment, which has outstanding practicality and promotion value.

P. Gereltuya — 2025-06-27

A crop rotation system has consists of various benefits such as reducing soil erosion and increasing fertility and crop yield. The experiment was conducted on the irrigation field of the formal potato seed multiplier Company “Elite seed” from 2015 to 2018. The main purpose of the research is to multiply the types of crops that are part of the potato rotation, to improve the structure, to investigate and determine the effect of the crops grown in rotation on the physical, chemical, and biological quality of the soil and how well they are to the next crop, and to solve the problems of crop development. Four types of potato rotations were included in the study, and in increasing seed potato yield and soil fertility green manure fallow — potato — wheat rotation or green manure had better benefits than other rotations (green manure plowing in the field in July). Soil samples were taken from 0-20 cm depth before the planting and after the harvest of potatoes each year. According to the results of the soil analysis of the experimental field, the humus content of the green manure fallow soil increased by an average of 0.35% with an improvement from another previous crop. Moreover, in the soil of green manure fallow the amount of nitrogen easily used by plants was 0.3-0.8 mg/kg (spring), which had a good effect on the yield of the potato crop planted the following year. The result of the experiment shows that the use of green manure fallow as a rotation with potatoes will improve the yield and quality of potatoes, therefore, this method is highly recommended in the future.
