How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Aim . To assess the quality of life of employees at the production facilities of Kostanay Minerals JSC. Materials and methods. From November to December 2024, the quality of life of 737 employees of Kostanay Minerals JSC was assessed using the internationally standardized SF-36 questionnaire. Quality of life was measured across 8 main scales, and differences between men and women were analyzed using the Mann – Whitney U test (p<0.05). The results reflect the level of physical and psychological well-being of the workers, and statistical analysis was performed using STATA software. Results and discussion. The mean age of respondents was 41.3±9.9 years, and the mean professional experience was 11±10.1 years. Most quality-of-life indicators were above average, with the highest scores observed in physical functioning, role-emotional functioning, and social functioning scales, while scores for «general health» and «vitality» were at an average level. Comparative analysis by sex showed that women had lower physical and psychological well-being compared to men. Conclusions. The majority of respondents rated their quality of life as above average. Although general health scores were similar between men and women, the overall quality-of-life index was higher in men. SF-36 scale scores ranged from 49.6 to 86.0 points, indicating a relatively favorable psychophysiological and emotional state among participants.
