Anthropometric Test Devices (ATDs) of different nominal percentile values have long been used as human surrogates in automotive crash testing. The Hybrid III family, which is one of the widely used ATDs in frontal crash test, was designed based on the anthropometry dimensions of US adults. Thus, this paper aims to assess the anthropometric differences between Malaysian adults and Hybrid III dummies in terms of 5th percentile (small female), 50th percentile (midsize male) and 95th percentile (large male). A series of anthropometric parameters of Malaysian adults was obtained from a database of 1321 subjects with 708 males and 613 females. The results revealed that the current midsize male population differs from the ATD’s statures and body weights by about 35 and 40 percentile points, respectively. This demonstrates that the current ATDs are not truly representative of the current Malaysian adults, which may potentially lead to different injury responses in road traffic crashes. Thus, car manufacturers may as well consider this discrepancy issue in developing their future models especially with regards to safety.
This paper studies the muscle discomfort among police officers when carrying out their work. The objective of this study is to give a basic introduction of ergonomic problems in among police officers and risk controls in relation to minimize the ergonomics risk factors. This paper gives quick review of muscle discomfort problems and prevalence of musculoskeletal disorders (MSD) among police officer. An ergonomic application has been purposed in the liter- ature to solve the problem related with design of mechanical.
