Title

THE PROPORTION OF THE EQUIPMENTS USED BY STUDENTS AND ERGONOMIC STANDARDS AND THEIR ANTHROPOMETRICAL CHARACTERISTICS

Pages

Abstract

 Purpose: The purpose of the research was to study the equipments used by junior, high school students (bench and DESK and height of blackboard) from ergonomical standards points and their relationship to anthropometrical dimensions of their users. Method: 203 junior male H.S. students with mean age of 13.6 ± 1.9 yrs. were selected as subjects and their anthropometrical measurements were taken. The equipments used by these students in their classes and the characteristics of the subjects' classes were also evaluated. The following measurements were taken from the subjects; standing and SITTING height, leg length, shoulder width, arm length, SITTING width, and visual line. The ergonomical characteristics of the BENCH, tables, including height width, slope, SITTING height and blackboard height were also collected. The correlation between the data was computed by using "relative-standard" method and referenced anthropometrical formulas through t – Students test. (P ≤ 0.05). Results: The results of this study indicated that: tables' height (73.6 cm) is higher than the suitable height of user's body characteristics (54.25cm). The height of the BENCHes and their body characteristics of users also showed significant relationships. However, the SITTING width didn't show significant relation (P ≤0.05). Also, the top of the tables and BENCHes' SITTING were without standard slopes degree. The blackboards were placed lower than the standards of the visual line of the subject (139.5) which called in ERGONOMY, as "easy visual line". So, it also indicated significant relation (p < 0.05). The information provided in the  questionnaire forms also indicated that 49/3% of the users were dissatisfied and felt some sorts of tiredness. The tiring condition they complained from with regard to ergonomic disposi6on of the furniture which were considered included 41/9%in the knee, 24.1% in the leg 51.2% in the back, 47.8% in the neck, and 24.6% from the high blackboard. Conclusion: The present study indicated that the equipments used in schools lacked standard ergonomics, and suitability with the students' characteristics. Importantly lack of the attention to this point may cause, postural deformities, fatigue, pain, and deficiency of students.
