The aim of this study is to identify the anthropometric differences among Malaysian, Singaporean and Indonesian, and analyse the compatibility of the anthropometric data with the selected Boeing 737 cockpit layout. The data of 16 anthropometric dimension for Malaysian, Singaporean and Indonesian adults were analyzed, arranged according to percentiles (5th, 50th and 95th)and compared. The result of comparative analysis between anthropometric data with the selected cockpit layout dimensions showed that the 95th percentile of anthropometric dimensionsof the Indonesian adult is compatible with the Boeing 737 cockpit layout. The results of this study could be used as references by the aircraft manufacturer to increase the effectiveness of the cockpit design in the future especially in considering the anthropometric data of ASEAN population
Aviation accidents still hit the news even though the growth of technological advancement on commercial aircraft avionic systems has been impressive. Hence, one of the objectives of this study is to plot the time-based graph of commercial aviation accidents, with direct consequence from avionics instrumentations in the period of two decades, from 1996 to 2015. The second objective is to analyse two main aircraft manufacturers, Boeing and Airbus, in determining specific model of its kind that significantly involved in avionics-related instrumentation as one of the contributing factors that leads to the incidents or accidents. The third objective is to identify which avionics system that most frequently involved in aviation incidents, for both manufacturers. The final objective is to examine the main probable cause that has the highest percentage in those accidents within the said time frame. The method of collecting data is by doing comparative analysis from reliable official websites of four well-known bodies such as National Transportation Safety Board (NTSB), Federal Aviation Administration (FAA), Aviation Safety Network and Flight Safety Foundation. Results show that misfortune occurrences are directly associated with avionics within the said two decades, which mainly involved Autopilot and Flight Management System (FMS) (14% each), meanwhile the aircraft model Boeing 737 carries the highest percentage of avionics-related incidents or accidents. Nonetheless, 67% of the misfortune occurrences within the scope of study are mainly due to human error instead of technology.
This paper aims to identify the risk of work-related musculoskeletal disorders (WMSDs) among nurses or patient handlers and to develop the assisted equipment in order to reduce the risk. The survey questionnaires have been distributed to the nurses in two medical centers in Klang Valley. The results indicated that they are exposed to the risk of WMSDs and one of the tasks contributed to the risk is changing bedridden patient diapers. Based on the interview conducted, there is no equipment available that could be used to assist in diapers changing process, and all the participants agreed on the idea to develop the Bedridden Assisting Support Equipment (BASE). The BASE has been designed and developed with the combination of the mechanical element, counterbalance systems, and ergonomic tools. The BASE is successfully performed its intended function in reducing the physical effort of nurses or patient handlers to change patient’s diapers which indirectly could reduce the risk of WMSDs. In addition, the BASE proved its effectiveness as only one person required when changing the diapers using BASE
This paper aims toinvestigatethe risk of physical fatigue at different levels of posture and repetition during manual handling task. Ten subjects with nohistoryof musculoskeletal disorders performed manual handling tasks at three levels of posture and two levels of repetition. The task completion time is recorded during the experimental task and the subjects rated their perceived discomfort level after the task completion. The results indicated that the lower posture of hand at higher repetition resulted in higher perceived discomfort level that leads to higher risk of physical fatigue. The higher repetition requires higher rest time for recovery and required lengthy completion time. The findings of this study served as a reference to the manufacturing industry in manual handling task design and planning to mitigate issues related to work-related physical fatigue at different levels of posture and repetition that could lead to the risk of work-related musculoskeletal disorders (WMSDs)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
