Development and Validity of Krik patrick\'s Evaluation Tool to Investiagte the Efficincy of the Training Course on Workers\' use of Hearing Protection Equipment

Background:The last strategy to protect workers' hearing against load noises is use of hearing protection devices. The efficiency of wearing headphone depends on its full time application. After education, we need to evaluate the efficiency of the conducted training course. One of the most important factors affecting a valid assessment is existence of an appropriate questionnaire to evaluate the course properly. Methods: In order to standardize and investiagte the validity of the researcher-made questionnaire, 12 experts were asked to review it. To determine the questionnaire's validity, we used the face validity and content validity. In order to determine the quantitative content validity, we applied the content validity ratio (CVR) and content validity index (CVI). Then, reliability of the questionnaire was investigated by Alpha-Cronbach method. Results: We designed 30 questions as the questionaire's items, containing five demographic questions, 10 response questions, four content questions, four learning questions, four behavior evaluation questions, and seven questions about the outcomes. In experts' content evaluation, questions with CVR of higher than 0.56 were selected; while, the CVI of the remaining questions was 0.91. The overall reliability of the research tool was 0.83 using the internal consistency.Conclusion: This study provided a valid and reliable questionnaire for assessing the Kirkpatrick model. This questionnaire can be used as an appropriate tool to evaluate the training courses in accordance with the BASNEF model to increase the duration of using headphones by workers. &nbsp

Effect of Integrated Management System on Occupational Hazards Reduction

Background: Today, organizations need to comply with environmental standards, employees, customers, and others in order to achieve competitive advantage and performance globally. One of these standards is an integrated management system. One of the standards in an integrated management system is safety and health that is currently being considered as one of the most important worldwide issues, and emphasizes the goals of identifying harmful factors, evaluating, controlling, and managing. This study tries to measure the efficiency of an integrated management system by analyzing the annual report of work place damage before and after implementing this system. Methods: This descriptive-analytic study was carried out in one of tile factories from 2009 to 2014 in Yazd. The data on the measurement of occupational harmful factors (sound, lighting, thermal stress, total dust) during the years of the study were collected and analyzed by the SPSS software version 19.Results: According to the results of measuring the harmful factors of the work place in this research, the establishment of an integrated management system on the environmental factors (sound, lighting, thermal stress and total dust) in the studied industry environment was positive and reduced issues out of standard and increased standard stations. Conclusion: The integrated management system establishment had positive effects on physical and chemical environmental factors and reduces costs, eliminates performance and ultimately improves the performance and efficiency
