The chemicals and petrochemicals industry is currently one of the world's leading international economies. But at the same time it also remains an industry where harmful, difficult and hazardous working conditions for workers are present. All occupational safety and health protection measures must be aimed at achieving the main objective of reducing the level of occupational diseases on the basis of, first and foremost, preventive work on risk factors. Professional activity at chemical and petrochemical enterprises reveals the necessity to develop a clear algorithm of occupational risk analysis, which has a common basis with assessment of other technical risks. The chemical and petrochemical industry is an industry with a large number of risks: risk of fire, risk of explosion, risk of leakage of harmful chemicals, risk of evaporation of harmful chemicals. All these risks entail risks of getting sick: respiratory tract cancer, etc. and the resulting disability or disablement. This article examines some methods of occupational risk assessment in the chemical and petrochemical industry. Analysis of methodologies such as the ranking of occupational hazards, the Kwij Al-Dalemi occupational risk assessment, as well as the French experience of the Laboratory Laboratory Network-Prevention Network-National Surveillance for Occupational Diseases (Research National de Vigilance et de Prevention des Pathologies Professionneles, RNV3P) and the US experience of LHAT-Laboratory for Hazardous Substances Assessment in Iowa State in the USA. The article details the methodology for ranking occupational hazards in chemical plants and shows the ranking of occupational hazards by priority and their short- and long-term exposure.
This descriptive work is aimed at studying at the micro level the socio-demographic indicators of the Abay region of Kazakhstan. The literature review highlights the importance of population dynamics, education, health care and internal migration for sustainable development in the region and in the country. The study also uses the fuzzy set method for several aspects of the selected indicators. Secondary data for 2010-2020 are taken from an open source - the Bureau of National Statistics and were used to identify negative trends and contradictions. The results showed that over the past 10 years there are negative trends in the region in terms of indicators: a high level of emigration, a shortage of able-bodied population, an increase in the number of schoolchildren with a constant number of schools, and a negative trend in hospital organizations. Beskaragai and Borodulikha districts natural population growth decreased by 62 percent. The number of schools in the region has slightly decreased, while in Semey (23%), Kurchatov district (30%) and Ayagoz (1.54%) district there is an increase in school enrollment. In Abay and Kokpekty districts, there is a decrease in the number of schools enrollment (-10% and -16%). The number of hospital beds has decreased significantly in most districts (more than 30 percent in half of the districts). In general, this article contributes to a deeper understanding of the socio-demographic dynamics of the Abai region. The results obtained can be used in making political decisions related to population regulation and economic development in each region.
This article shortly researches how does it work: one of the popular free online platforms called Khan Academy to study Mathematics in the perspective of methodology of teaching. Khan Academy is free online platform with video tutorials and explanations with exercise dashboard for learning subjects like Mathematics, Science and more. This digital resource provides statistics for teachers to monitor the progress of students. In this article written explanations why it is effective and how it could be implemented to Kazakhstan’s schools. The method of research is observing the experiences of overseas schools by analyzing articles and additionally made a personal observation of the platform. Schools in the American continent use flipped classes with Khan Academy to learn Mathematics inside and outside of the class effectively for non-cost. This idea of flipped class for mathematics would be efficient in Kazakhstani schools for secondary school students and also for students who are preparing for taking National Common Test for entrance to university.
Goals and objectives of the research: To raise awareness about maintaining self-learning skill for the students of schools and their parents in order to investigate into human capital. The objective is to identify the advantages, disadvantages of blended learning in Math classes at schools with Kazakh linguistic groups and find out the proper implementations considering culture and perception of Kazakhstani families of the middle class. Methodology: Mixed methods such as surveys and experimental classes were used. Results/Findings: The self-learning skill is not developed in a majority of the students, however, there are bunch of problems related to this obstacle. Starting from the technological limits and internet access, ending with the not sufficient developments of the content for Kazakhstan’s students online. Novelty/Originality/Value - The work with the students is performed in a relatively short period of time (3 months) by conducting classes. This is the first research done in ordinary comprehensive school and in Kazakh linguistic group on the usage of digital resource in English within the class of Kazakh linguistic Math class. Theoretical or Practical Implications: The results of the experiment can be related to the primary data. The implication of the research can be used in conducting experiments in other schools to identify the tendencies of students in raising self-learning skill to invest into the human capital and its perspectives in economic sphere which includes education.
