Antropometrik değişkenler kullanılarak Nijerya'nın Ondo eyaletindeki ortaokullar için uygun sıra ve sandalye tasarımı ve geliştirilmesi

Abstract

Furniture provision is a major component of teaching and learning facilities in schools which is usually done without considering the body measurements of users leading to discomfort for the users. A survey of anthropometric measurements of secondary school students in Ondo State of Nigeria was carried out alongside the size of existing chairs and desks in order to determine the level of mismatch. Obtained data were analyzed and the population of students was grouped into 5th, 25th, 50th, 75th, and 95th percentiles. In Ondo State, Bio-characteristics of the students showed that the average age of students from JSS 1-SSS 3 increased from 10 years for JSS 1 to 16 for SSS3 which conformed with the entry and exit age requirement. Ergonomically compliant furniture was designed with adjustable features using 36.25 cm as the lower limit point and with the upper limit of 46.85 cm for seat height while lower limit was 54.46 cm for desk and upper limit having 67.60 cm. With these measurements, a typical desk and chair was produced by using round pipe and laminated board. Selection of non-adjustable furniture is both impracticable and unsuitable for a large of people; hence provision of adjustable compliant furniture was preferred to accommodate the entire population.
