The Model of Ergonomy Intervention and Evaluation and Role to Improve Administration in Yazd Agricultural- Jihad Educational Center

Lack of attention to theoretical and practical knowledge of ergonomics is essential forthe ergonomic research. In this study، a model was designed to support knowledgebasedtheory of guiding and evaluating the processes of developing ergonomic interventions in Yazd Agricultural Education Centre. Results of the Total (micro and macro) ergonomic interventions have shown positive effects of the application of this knowledge on the improvement of Education Centre’s management. So، it became clear by reviewing the financial and non-financial statements that as compared to the initial (base) year، t application of the present model has caused a decrease in the costs and increase in revenue with less expansion of work load on the manpower. Morgan''s Table was utilized to select the sample treatments. On the other hand، by using simple and random sampling with the sample size of 77 (N1 = 94) and 133 (N2 = 200) persons for the control and sample populations، respectively، the amount of musculoskeletaldisorderswas also investigated. Analysis of the questionnaire data of body mapping throughχ2-test has demonstrated a significant difference (P= 0. 01) between several dimensions of the quality control and sample population. Therefore، the degree of discomfort for qualitative dimensions was more in the control population as compared to the sample population، which indicates the positive impact of total ergonomic interventions in improving the management and reducing the musculoskeletal disorders in the Yazd Agricultural Education Centres.
