Problem statement: High demand for products in the manufacturing industry had driven the human workers to work faster and adapt to their un-ergonomically designed workstation. Some tasks at assembly workstations require human workers to stand for a prolonged period of time to assemble the products. Approach: This study was conducted at an automotive component manufacturer. Twenty full time workers working at the assembly line participated as subjects in this study. Observations were made and recorded with respect to working postures practiced while performing their assembly tasks. In addition, subjects anthropometric data and current workstations dimensions were measured to determine whether they are suitable or not to perform the assembly tasks. Results: The findings from this study showed that there are four types of awkward postures and anthropometric data mismatches that had contributed to Musculoskeletal Disorders (MSDs) problems, faced by the subjects. Conclusion: The findings from this study shows the current assembly workstation at Company A need to be redesign to eliminate awkward postures and anthropometric mismatches to lower MSDs problem and improve productivity among assembly workers
Road crossings are considered as an unavoidable part of walking in which the desirable route of pedestrians interacts with vehicles. This interaction may expose the pedestrians to risks or delays. Pedestrian- vehicle collisions are regarded as the most serious type of accidents since they incur high fatality rate of nearly 13 percent. This study has been carried out to fulfil two objectives. First, to identify the contributing factors to road crash, and second, to understand the implementation and effectiveness of a preventive device to reduce road crashes involving pedestrians. Collision avoidance and mitigation systems such as the AEB are intended to reduce accident risks by automatically applying the brakes prior to an accident. Understanding the human action, style and behaviour are the key elements in producing the ideal AEB Pedestrian for the future. This study sheds light on the future direction in the area of road safety by considering preventive actions to reduce the occurrence of road crashes, particularly among pedestrians.
Long distance driving could result in driver’s fatigue. Driving fatigue has been identified as one of the main reasons behind fatal crashes and injuries. This study aims to identify the body parts that experience fatigue and investigate factors that contribute towards driving fatigue among long distance heavy vehicle drivers. Two methods were used to collect information; first, an oral face-to-face interview and second, a self-administered survey questionnaire. A set of questionnaire was developed, pilot tested for its reliability and validity; and distributed to the respondent. Respondents were 60 heavy vehicle drivers from Klang Valley. Majority of the heavy vehicle drivers agreed that long driving hours is the main factor that causes fatigue. Both oral interviews and survey findings showed that all respondents experienced fatigue while driving. Majority of them start to experience fatigue after two hours of driving. In addition, the result of this study shows the drivers experienced severe discomfort on shoulder and low back. Majority of them highlighted that lack of sleep before starting the journey is the main fatigue cause. In conclusion, the heavy vehicle drivers should have sufficient sleep before long distance driving and take a break after two hours of driving.
This paper discusses the roles of professional engineers (PEs) who are attached to the Institutions of Higher Learning (IHLs) and how their contributions are as important as their counterparts in the industry. This paper highlights the roles for PEs at IHLs based on a survey conducted at selected IHLs in Malaysia. Academician-professional engineers have crucial responsibilities to develop graduates who later promote safer and cutting-edge engineering solutions. These new technologies will make Malaysia an environmentally healthier place and further prepare Malaysia towards a developed nation at the end of the decade. From the survey, we conclude that PEs at IHLs make use of their professional qualifications to enhance their knowledge therefore provide better work quality. We also found that lecturers with these qualifications have higher confidence in their own ability to success in their careers and to face and help the public.
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.
