This is sometimes called the study objective. The key objective of this study was to resolve the occupational challenges affecting the truckloaders in the Nigerian block-making industry. Particularly, the researchers tried to clarify the possible benefits of adopting the Ergonomic Method of Lifting (EML) vs the common Un-Ergonomic Method of Lifting (UML). 2) What was the study design(s)? The study analyzes the EML adoption in the block-making industry of Nigeria using qualitative and econometric methods of inquiry to understand the experiences of workers and the economic effects of the application of EML. 3) What population was studied, and how were subjects selected? Also, describe the control or Comparison group if applicable. The study sought to understand the effect of the Ergonomic Method of Lifting among the workers and managers in 25 Southwestern Nigerian block-making industries by looking at experiences, challenges, and perceptions. 4) How was exposure defined, and how was it measured? The study assessed the influence of non-ergonomic lifting practices (UML) on the truck loading workers. It looked at lifting time, pace, and task quality so ergonomic training functions could be proposed to match it with ergonomic lifting methods. 5) What was the outcome, and how was it measured? The study compared the Ergonomic Method of Lifting (EML) to un-ergonomic methods in truck loading in the block-making industry. EML was efficient, cost-saving, increased efficiency, and improved task quality; UML was cost-saving. 6) How were the data analyzed? The Ergonomic Method of Lifting (EML) on truck loaders in the block-making industry of Nigeria was assessed by considering subjective accounts and economic aspects. It utilized an independent-sample t-test that compares benefits and personal experiences. 7) What were the results? The research shows that the Ergonomic Method of Lifting (EML) significantly enhances efficiency, reduces spoilage, and lowers medical expenses, as 82% of workers prefer it to its long-term benefits. 8) What sources of bias, confounding, and random error were addressed? The article did not explicitly mention the sources of bias, confounding, or random error that were addressed. 9) What sources of error were unaddressed, and how might these affect the results? The unaddressed sources of error should be specifically mentioned in the article. 10) What conclusions did the author draw, and were they justified? The authors based their conclusions on the physical increase in actual productive hours, reduction in wastages, and lower medical costs in modernization under EML. In addition, they stressed the importance of enlightenment...
