New Zealand studies have identified up to 96% mismatch between the dimensions of school furniture and student body size. Poor posture in students using school furniture is considered to contribute to the prevalence of musculoskeletal disorders. This paper describes the development of dynamic furniture designed to be appropriate for the sizes of students in years 1-13 (ages 5-17 years) and condu...

Musculoskeletal symptoms are one of the top ten health problems among schoolchildren in Hong Kong. Whether or not these symptoms are related to school furniture has yet to be determined and published data on furniture size are lacking. The purpose of the study was to determine whether the design of furniture in schools is appropriate for children's anthropometry. A total of 214 volunteer subjec...

nappropriately designed classroom furniture that does not take children’s anthropometric measurements into account has a negative effect on musculoskeletal systems. In this study, which kept Covid-19 pandemic policies in mind, students’ static dimensions were measured and their descriptive statistics calculated, using mean, standard deviation, percentiles, statistical tests, including the t-tes...

the quality function deployment (qfd) is a very helpful method to analyze the customer's desires with solutions of problems along a new design to generate high quality and competitive developed products to generate high quality and competitive ergonomic products and processes. this method employs a wide range of applications for translating customers’ needs into technical requirements to f...

Traditional approaches to semantics give a logical, settheoretic account of category conjunction, where an item is a member of a conjunction A&B only if it is a member of both single categories A and B. However, people do not always follow this logical approach when classifying items in conjunctions. For example, Hampton (1988) found that people typically classify blackboards as non-members of ...

Ergonomically unsuitable school furniture is frequently considered one of the major causes of severe posture problems in adulthood. This study was designed to determine the ergonomic suitability of educational furniture in the lecture theaters at the University of Ibadan to serve as a case study. Sample of convenience was used to select participants for this study. The lecture theaters were sel...

Tests were conducted to compare the performance characteristics of school chairs constructed with pinned but unglued round mortise and tenon joints with those of chairs with glued but unpinned joints. Chairs with 0.125-inch cross pins in 0.723-inch diameter tenons developed over 90 percent of the strength of the chairs with glued tenons, whereas chairs with 0.313-inch diameter pins developed on...
