Exposure to elevated levels of ambient particulate matter (PM 2.5 ) leads to premature mortality and considerable economic losses.
This study examined the effect of a six-month virtual mindfulness program on the emotional stability of school psychologists in Kazakhstan and Russia. The goal was to assess whether structured mindfulness training leads to significant improvements in emotional well-being. A quantitative approach was used. School psychologists were randomly assigned to an experimental group that participated in the mindfulness program or a control group with no intervention. Emotional stability was measured using the Eysenck Personality Inventory (EPI) before and after the intervention. The results indicated a marked improvement in emotional stability in the experimental group compared to the control group. Participants who underwent the mindfulness training demonstrated a marked reduction in emotional instability, as reflected by large effect sizes and statistically significant differences in post-test scores. These results were consistent across both the Kazakhstani and Russian experimental groups. The findings support the effectiveness of virtual mindfulness programs in enhancing the emotional stability of school psychologists. The study contributes to the growing literature on mindfulness-based interventions and underscores the value of digital communication methods in promoting mental well-being within professional development programs, particularly in non-Western settings.
Teachers working with children with special educational needs face high levels of emotional and psychological stress on a daily basis, which increases the risk of professional burnout. In the context of modernizing education and increasing demands on teaching, the study of factors determining teachers’ ability to maintain mental health and professional effectiveness is becoming particularly relevant. This article provides evidence of the correlation of indicators of emotional burnout syndrome (CMEA) with naturally determined individual psychological characteristics of a person, namely– interhemispheric asymmetry of the brain. The article examines the functional sensorimotor asymmetry of the brain as the biological basis of stress tolerance of the personality of a special educator. The problem of stress tolerance of teachers working with children with special educational needs is one of the most acute in the modern education system. Their work requires constant emotional involvement, high responsibility and the ability to solve complex, sometimes non-standard tasks. Chronic psycho-emotional stress combined with insufficient social and financial support significantly increases the risk of professional burnout. Modern scientific research has proved that personality formation depends not only on the system of upbringing, education, and specialist training in ways of behavior in various pedagogical situations. The characterization of a biologically determined factor, namely, the interhemispheric asymmetry of the brain, should be the basis for understanding the nature of individual differences. This phenomenon provides individual differences in cognitive processes, interpersonal interactions, and responses to stressful situations. The presented study proves the correlation of stress tolerance and sensory asymmetry of the brain. Thus, taking into account biological and psychophysiological factors in the development of preventive and correctional programs can significantly increase the effectiveness of teacher support and reduce the risk of professional burnout.
The growing global demand for fish necessitates the exploration of sustainable aquaculture practices. This has led to a focus on the quality and sustainable production of fish products with minimal environmental impact. Thus, the objective of this review is to study and evaluate how different aquaculture systems impact the quality and nutritional profile of fish. Fish are rich sources of protein, containing almost 20% protein and essential amino acids and vitamins. The nutritional value and quality of fish products are directly related to the conditions under which they are produced through aquaculture. This article considers various aquaculture systems, including closed-loop systems, pond farming, marine aquaculture, and aquaponic systems. The operating principles, advantages, and inherent limitations of each fish-rearing system are subjected to rigorous critical analysis in this review. Such practices are necessary to meet the growing demand for fish and to maintain the integrity of aquatic ecosystems for future generations.
The paper investigates the technology of refining primary aluminum from vanadium impurities, based on flux treatment with boron-containing fluxes. In the Pavlodar region of the Republic of Kazakhstan, on the basis of local enterprises, the production of primary aluminum and products based on local raw materials is developing. The main problem in the production of primary aluminum on the basis of JSC “Kazakhstan Electrolysis Plant” is the presence of undesirable vanadium impurities, which pass into metal during electrolysis from baked anodes based on calcined coke (vanadium content up to 800 ppm) of the local enterprise LLP UPNK-PV (Pavlodar, Kazakhstan). The authors investigated the process of ladle refining of aluminum from vanadium using the Al-B (3% B) alloy. Laboratory and industrial tests have shown a decrease in the vanadium content by an average of 78% in the bulk of the metal, with an increase in its content in volume up to 5-10% of the ladle capacity. It was found that mixing leads to a certain averaging of the vanadium content in the ladle volume.
