One of the propounded subjects in ergonomics is anthropometry, which measures the human body dimensions in order to have the appropriate dimensions between the equipments and the users.. Using anthropometric measurements, valuable data will be achieved which eventually leads to national and regional standards. The main objective of this study is designing anthropometric tools for static anthropometry measurements.   Methods   Available samples were assessed based on interview with experts in different disciplines and also literature review in on-line databases. Following the assessment of local and exported samples, and according to the analysis of social, environmental, market, practical, static, structure, assembling and material, systematic, standard and packing aspects, the characteristics of an anthropometry device were determined.   Results   Examining the pros and cons of available local samples in several academic centres, this was revealed that anthropometry portable devices should be produced in larger amounts so as to reach the goals.   Conclusion   In this study, a portable anthropometry device was designed for mass production according to anthropometric characteristics of Iranians. This device, due to the design, unique specifications, easy to use, lightness, few pieces used, and suitable costs, could be used in different   places.}, Keywords = {Static Anthropometry, , Portable, body segment}, volume = {5}, Number = {1}, pages = {6-14}, publisher = { Iran University of Medical Sciences}, url = {http://ioh.iums.ac.ir/article-1-113-en.html}, eprint = {http://ioh.iums.ac.ir/article-1-113-en.pdf}, journal = {Iran Occupational Health}, issn = {1735-5133}, eissn = {2228-7493}, year = {2008} } @article{ author = {Habibi, E. and Amini, N. and Porabdian, S. and Rismanchian, M.}, title = {Assessment of relationship between Macro Ergonomic conditions and employees work satisfaction Touse-eh and Omran factory}, abstract ={  Background and aims   Background and aim: Macro ergonomics is a social - technical attitude which in the manner of top down proceeds to look at organization planning , work- system and also planning of human - machine , human -environmental , human- job interaction and emphasizes on employees participation and make plenty use of it.   Methods   This descriptive - analytical study is of cross - sectional type. Data gathering method  is based on observation and questionnaire. The society under study includes 83 personnel (employees) of a factory which is a subsidiary of Iran Khodro. We used two questionnaires in this  study. One is questionnaire to verify macro ergonomic situation which planned and consisted of  30 questions that investigated different factors in working environment and was verified in terms  of stability and reliability (cronbach alpha = 0.72) and the other one was Minnesota job satisfaction  questionnaire which was distributed among people.   Results   This research shows over 1,500 extended hour's male workers, 69 percent of whom  reported "Chronic or Frequent" back pain, while 52 percent reported "Chronic or Frequent" wrist  pain. Sleep deprivation could possibly be damaging in terms of muscle, ligament, or tendon  injury. With the average extended-hours employee sleeping only 5.1 hours to 5.5 hours each day when working a night shift, they could face an increased risk of ergonomic injuries. The mean age of people under investigation is 30.8. Most people are in age group of 26-30 (44.6%) most  individuals have 4 to 7 years working experience (56.6%). Macro ergonomic mean score in total  society under study was obtained as 59.8. The highest score of job satisfaction has been related to middle managers (69.2). Pearson correlation test showed that there was a direct relationship between general domain of macro ergonomic and job satisfaction.   Conclusion   There is a consistency between main enhanced results in our study in terms of macro ergonomic situation with the result of similar studies of barariyan (2006) and rajabzadeh (2002) that have used RSI (Relative Stress Index). Also there is a correlation between the result of  our study job satisfaction with the results of similar studies such as Bassy's (2002) in Swedish employees , Garcia and Molina's (1999) in Spanish employees and the result of Partovi study  (2006) in Esfahan steel plant employees and Davari's (2003) in employees of Esfahan Shahid PowerStation.}, Keywords = {Macro ergonomic, Micro ergonomic, working hours, work satisfaction }, volume = {5}, Number = {1}, pages = {15-20}, publisher = { Iran University of Medical Sciences}, url = {http://ioh.iums.ac.ir/article-1-115-en.html}, eprint = {http://ioh.iums.ac.ir/article-1-115-en.pdf}, journal = {Iran Occupational Health}, issn = {1735-5133}, eissn = {2228-7493}, year = {2008} } @article{ author = {Hazavehei, SM. and Shadzi, SH. and Asgari, T. and Pourabdian, S. and Hasanzadeh, A.}, title = {The effect of safety education based on Health Belief Model (HBM) on the workers practice of Borujen industrial town in using the personal protection respiratory equipments}, abstract ={  Background and aims   Every year 50-158 million occupational diseases and job accidents occur in the world. Studies on the job injuries show that about 150000 injuries occur annually in  Iran. Unhealthy behaviors are important problems in public health. Education is one of the best ways to change unhealthy behaviors. Interventions based on model and theories have many  capacities for behavior change. Health Belief Model is one of the health education models that are  useful for behavior change. This research has been performed in order to assess the effect of health  education program based on health belief model (HBM) to prevent occupational respiratory   diseases in workers.   Methods   Aquasi-experimental design was used for this interventional study, in which 88 of workers of Borujen industrial town participated, who were randomly assigned to experimental and control group. Data collecting tool were a self-administered questionnaire including 53 questions based on health belief model that was completed by the workers, in addition to the performance check list which was conducted by researcher via insensible controlling the workers' safety behaviour. Validity and reliability of the tools were examined prior to the study. Educational  intervention was conducted in the first stage following by the second data collection one month  later. The data of both experimental and control group were compared statistically before and  after the intervention.   Results   The results showed that the mean of the grade of all parts of health belief model  (HBM) and performance mark of the workers about safety and use of personal respiratory  preventive equipment in experimental group after educational intervention compared to prior the  study and also compared to control group were significantly increased.   Conclusion   The results of this survey showed that by enhancement of health belief model (HBM) components including perceived susceptibility, perceived severity, perceived barriers  and perceived benefits, adopting preventive actions increases, too.
