There is a need to support the occupational safety and health (OSH) practitioners defining their priorities action for improving working environment condition and minimizing the risk factors in the early stage of development. This paper aims to identify the critical risk factors of occupational ergonomics among production workers in an automotive component manufacturer. The Analytic Hierarchy Process (AHP) was utilized to prioritize the level of four ergonomics risk main factors and 26 sub-factors. The linear interpolation and a probability value were given by the practitioner to identify the magnitude of risk. In conclusion, physical factors (0.3143) and psychosocial factors (0.2920) were ranked as the two most important risks of occupational ergonomics. The main effective sub-factors initiating occupational ergonomics risk were found that include force exertion in job task (15), carrying and lifting the heavy load (13.91), high workload (13.04) and work stress (11.89)….

Workers in the automotive industry are exposed to various manual material handling activities that lead to Work-related Musculoskeletal Disorders (WRMSDs). Lifting and lowering loads are the main activities in the development of low back pain among the workers. A cross-sectional study was conducted to calculate Recommended Weight Limit (RWL) and Lifting Index (LI) for the selected lifting and lowering activities and to determine the prevalence of WRMSDs symptom among the workers. 120 male subjects were selected through purposive sampling. Standard Nordic Questionnaire (SNQ) was applied to identify WRMSDs. Meanwhile, NIOSH Revised Lifting Equation (NRLE) was used to evaluate job activities. Recommended Weight Limit (RWL) and Lifting Index (LI) for lifting and lowering tire were 11.78 kg (RWL origin) and 13.32 kg (RWL destination); 0.67 (LI origin) and 0.60 (LI destination) respectively. Meanwhile, RWL and LI for lifting front car bumper were 4.13 kg (RWL origin) and 3.72 kg (RWL destination); 1.40 (LI origin) and 1.08 (LI destination) respectively. The highest musculoskeletal disorder prevalence was lower back (39%), followed by shoulder (14%), upper back (11%), elbow (11%), neck (7%), wrist/hand (7%), ankle/feet (7%) and knees (7%)…

Rubber tapping involves repetitive and high paced work, static muscle loading, non-neutral body postures, forceful physical exertion, and many other potential risk factors for development of work-related musculoskeletal problems (WRMP). In this research, a cross-sectional study was carried out to identify the prevalence of WRMP among rubber tappers, to determine the psychosocial factors that contribute to WRMP, and to explore the relationship between psychosocial factors and physical factors among rubber tappers. Data collection was done using three instruments, namely Nordic Musculoskeletal Questionnaire (NMQ), Job Content Questionnaire (JCQ) and Rapid Upper Limb Assessment Tools (RULA). In total, 70 rubber tappers participated in this study. Results obtained in study revealed that majority of the rubber tappers suffering from lower back pain whereas in terms of psychosocial factors they have low social support and high job and physical demand. WRMP among rubber tappers are cannot be doubtable, however the risk can be reduced if the management of occupational safety and health risk is managed properly.

Number of accident cases reported to the Malaysian Social Security Organization (SOCSO) which are related to the number of diseases of musculoskeletal system and connective tissue is increasing rapidly since 2013 to 2017 where most of the accident cases reported comes from the manufacturing industry. Work related musculoskeletal disorder (WMSD) often happens among the workers due to manual material handling (MMH) while performing their everyday working task. The workers in printing and publishing industries especially in distribution section are exposed to risk of getting WMSD diseases. This is because every worker in the distribution section needs to perform MMH tasks such as lifting, bending, twisting, pulling, and pushing which involves repetitive motion. The objective of this study is to investigate the prevalence of musculoskeletal disorders diseases among the distribution workers by using multiple ergonomic assessment analysis such as Nordic Discomfort Questionnaire, Quick Exposure Check (QEC) Questionnaire and REBA Analysis. The results….

Musculoskeletal disorders (MSDs) is one of the most common injuries to the physiotherapists at the treatment center. There are many factors leading to this problem, such as repeated movement, manual handling of heavy equipment, and inappropriate posture. Therefore, the aim of this paper is to identify the risk of MSDs among physiotherapist and investigate the specific treatment designs. This study used questionnaire method that has been distributed to patients and physiotherapist at one of the treatment center in Peninsular Malaysia. Rapid Entire Body Assessment (REBA) was performed also on the physiotherapist to evaluate the effectiveness of the equipment before and after improvements. There were three equipment that have been considered in this study; hydro collator pack, luminous and non-luminous infrared machine. Based on the questionnaire, majority of the physiotherapists were exposed to the risk of MSDs in their occupational task. The REBA’s finding shows there is a decrement of the score after improvement have been made on the luminous machine. Based on paired sample tests on the REBA score before and after improvements, the P value (significance<0.05). It proves that there is a big different in the REBA score after the tools was modified. In conclusion, this study was related to assessments and improvements that can be performed on treatment equipment and the tasks among physiotherapist.

The discussion in this research is about how the utopian ideology that emerged from designing ordinary products demanded by mass consumer markets triggered the plastic monobloc pandemic and influenced social reformation, both in aesthetics aspects of industrial design applications, and in equalising the global post-World-War II economy. Modernism through mass production processes provides a platform for social response by urban designers, who strive for more sustainable ways to achieve idealised utopian conditions by introducing characteristics of durability, cheapness and sturdiness, while developing mass production techniques. The ubiquitous monobloc chair is an example of social activism in design thinking, as mass manufacturing enables society to afford less costly, everyday furnishing materials such as injection-moulded plastic chairs. From the creative standpoint, many in design fields may disqualify and disclaim the value of homogenous plastic furniture as a tangible expression of social reformation. Nevertheless, monoblocs ride on the mass-consumer utility factor and is promoted from economic benefit rather than aesthetics standpoint. What should we make of this, and how does design modernism fit into the 21st-century ideals of “utopian” society today?
