Ergonomic and anthropometric consideration for library furniture in an Iranian public university
In our competing educational world, students spend a considerable part of their daily life, studying at library furniture. Not surprisingly, due to lack of proper anthropometric databases, these products have typically been ill fitted for the intended user populations.
To verify the optimum anthropometric match of library furniture within an academic environment, through a combined qualitative and quantitative approach.
267 (120 female and 147 male) students, were subjected to 11 standard anthropometric measurements. In line with the measurements, subjective evaluations were also considered through detailed fitting trials on selected groups of participants.
Combinational equations defined the unacceptable furniture dimensions according to elbow and sitting popliteal heights, mainly for smaller and taller divisions of the studied population, which were systematically comparable along with subjective and objective outcomes. In brief, if we classified studied students into "small," "medium," and "tall" groups, the design dimensions should be altered by -5.1, -2.2, and +1.6 cm for chair seat height; and by -8.3, -5.4, and +1.1 cm for table height, for each student group, respectively.
The furniture size to be used by Iranian students should be changed to fit their anthropometric measures.

In most armies, clothes, equipment and weapons are designed according to the physical characteristics and anthropometric data of soldiers.
To study the anthropometric characteristics of Iranian army force and their changes over recent years.
12 635 Iranian military personnel aged between 18 and 30 years with tenure of <10 years who were normally engaged in educational military activities and soldiers were enrolled in this study, which was conducted in 2010.
The military personnel had a mean±SD stature of 174.1±6.3 cm and sitting height of 89.7±3.8 cm. They had a mean weight of 70.0 kg, and body mass index of 23.3 kg/m2.
The stature of Iranian army has increased by 14 mm during the last 15 years. The stature was less than those of the western countries and 3-4 cm more than those of East Asian personnel. The body mass index has had an increasing trend.

ABSTRACT: This study utilized a participatory ergonomics approach to examine the ergonomic hazards and reduce musculoskeletal symptoms for librarians in the East Baton Rouge Parish Main Library. A variety of research activities were conducted, including: ergonomics training and tests, observations, work environment and health questionnaires, and focus group discussions. A total of 39 employees from 9 different divisions in the Library participated in the study. The results of pre- and post-training ergonomics knowledge tests indicate significant improvement of librarians' understanding of ergonomics principles. The questionnaire responses for both 2-month-post- and 8-month-post- ergonomics training compared against those before the training have shown positive improvements in ratings of the presence and severity of a majority of the musculoskeletal symptoms, the design of computer workstations and manual material handling tasks, as well as perceived control over the work environment. With the identification of ergonomic hazards through RULA (Rapid Upper Limb Assessment) and REBA (Rapid Entire Body Assessment) observations as well as focus group discussions, the study findings accomplished the project's overall objective of assisting librarians with improvement of ergonomics in the workplace. The results of this study provide a necessary foundation for future long-term study of participatory ergonomics to reduce musculoskeletal injuries and disorders for librarians.
