“…In the current investigation, a specific gender was studied, although similar studies (23) have targeted both sexes. Such studies have been conducted in similar industries, with comparable workstations, although only Chiasson investigated six industries with different natures (14). Results from Nordic questionnaire showed statistical significance of SI for our left-handed workers.…”

“…One of the special characteristic is the evaluation method of attention to the psychological aspect or stress, resulted from work. Finally, the whole points gained from each posture are independently calculated with the following formula comprising exposure level for action level and ergonomic intervention (13)(14)(15): E% = (E/Emax) x 100, where E is referred to as exposure. Action level is divided into four levels, in which, the third and the fourth levels are required to the amendment measures, considering that, at the fourth level, these measures must be immediately performed.…”

Background: Work-related musculoskeletal disorder in upper-limbs (WRMSDs-UL) is one of the major complaints among the female machinists in gas supply parts manufactories, in some of which the noise reaches 85 dB and beyond. Objectives: The most important aim of this study was to evaluate the effects of noise and postural stress on strain index (SI) among these workers. Materials and Methods:The sample size was set at 50 subjects, comprising of two study groups; group 1 were exposed to noise ≥ 85 dB, group 2 were exposed to noise < 85 dB, while the official workers were selected as the control group. A Nordic-style questionnaire was used to collect information. Postures were assessed by observing each task, and then SI and quick exposure check (QEC) checklists were completed. The variability of effort intensity was measured by recording the subject's heart rate during her work and also, a sport tester machine was used for this aim. The Borg scale and then SI were calculated. Noise was measured by sound level meter and noise dosimeter, according to noise type. Data analysis was performed by using the Mann-Whitney, Kruskal-Wallis, one-way ANOVA, Spearman and Pearson correlation in SPSS (ver. 16) software. Results: There was no significant difference between work experience, age, dominant hand and marital status in the target groups (P > 0.05). Results showed a significant statistical relation between work experience and neck pain, shoulders pain and wrist/hand pain. They showed that there existed a different strain index between two groups, although not statistically significant. The Mann-Whitney test showed that there was a significant difference between the two groups from QEC posture score. Spearman correlation coefficient proved that QEC rating is directly related to the value of the SI. Conclusions: Postural stress among female machinists can increase the level of SI to fairly risky and dangerous. Also, changes in rating hand/wrist QEC scores with hand/wrist SI score were proportional in the studied samples. The SI can increase under the influence of noise above 85 dB, although it is not statistically significant.

Oil palm workers perform daily activities that exposed themselves to various ergonomics risk factors. To harvest oil palm fruits from tall trees, specific technique is required. To quantify the ergonomics risks factors, postural analysis was conducted using Quick Exposure Check (QEC) system. It was found oil palm workers were exposed to many postural problems while performing harvesting and collecting fresh fruit bunch (FFB) activities. However, to quantify the actual load, many limitations of the QEC have been revealed such the missing of legs assessment, the crude analysis for arm and shoulder, no pushing and pulling assessment and the biased may be existed due to the workers' perception on the ergonomics factors. Thus, it can be concluded that QEC system was not suitable for conducting postural analysis during harvesting in oil palm plantation especially in tall trees due to the above limitations.

“…Several literatures had suggested that the effect of low performance by the workers can have significant economic and social consequences [4,5,6,7]. This can be seen by the compensation claims for the employers that are increasing which may overburden the health system [8,9]. One of the major reasons for sick leave and work injuries in industry is due to the inefficient of production ergonomics.…”

Abstract. Musculoskeletal disorder (WMSDs) is the common health problems for the industrial workers. This health problem can contribute to long term effect on the production performance. The objective of this study is to analyze the posture of industrial worker in packaging industry using the RULA assessment in CATIA P3 V5R14 software. The working posture was reconstructed and developed in the CATIA P3 V5R14 software and then RULA assessment was conducted. From the RULA analysis, several awkward postures were detected to be high in risk factors. The postures in risk are postures 1,2 and 5 which mainly involve lifting heavy product and excessive bending. As a conclusion the RULA assessment was able to detect the problematic postures and further improvement can be conducted to avoid discomfort or further health complication.
