Subjects participating in a study on the ergonomics of tea-leaf plucking operations were so categorised, and the results have been compared with the existing groupings followed by the Tea-estate authorities. Such a method could facilitate predictive selection of pluckers, selection for training, and formation of groups in future studies.

This study aims to present and exemplify methodology for incorporating ergonomics pro-actively into the design using computer-aided design and digital human modeling-based analysis. The cleaning equipment is parametrized to detect the critical variables. The relations are then constrained through the 3DSSPP software-based biomechanical and experimental analysis using a prototype. MATLAB and Minitab software is used for optimizing efficiency while satisfying the established constraints. The experiment showed nearly 67%, 120%, and 241% successive improvement in the mechanical advantage in comparison to their immediate predecessors. A significant (6 point) reduction in rapid entire body assessment score has been observed in the final posture while working with the manipulator. 3DSSPP suggested that the joint forces during the actuat...

The present study aimed to investigate the extent of postural discomfort in CNC machine operators, and the relationship of this discomfort to the display and control panel height, with a view to validate the anthropometric recommendation for the location of the display and control panel in CNC machines. Methods: The postural discomforts associated with CNC machines were studied in 122 male operators using Corlett and Bishop’s body part discomfort mapping, subject information, and discomfort level at various time intervals from starting to end of a shift. This information was collected using a questionnaire. Statistical analysis was carried out using ANOVA. Results: Neck discomfort due to the positioning of the machine displays, and shoulder and arm discomfort ...

The Network was created to promote and develop ergonomics in BRICS countries, collaboratively represent the BRICS countries at the level of the IEA and ensure that professional standards of ergonomics, in teaching, research and practice, are maintained. This paper offers a short overview of the history of each BRICS country's ergonomics society, in which we highlight the impact of key individuals, events and milestones on the development of ergonomics in the respective countires. We then provide an overview of the current challenges faced by BRICS countries, with respect to the dissemination of ergonomics, which is proceeded by a snapshot of how the intended activities of the network will address these. We conclude by emphasizing how the BRICS plus network has the potential to create globalized ergonomics graduates, educators and researchers, who will continue to foster the advancement of ergonomics in their countries and more globally.

One hundred and forty women workers from Tuticorin district were selected randomly. Skin temperature was measured using Infrared Thermography. Temperature of the phalanges (fingers) of hand areas during work were as low as 26.57±3.06 0 C , i.e. 8C less than the pre exposure values and the temperature of the phalanges (toes) of feet areas (without gumboots) during work were as low as 25.70± 3.14 C , i.e. 9C less than the pre exposure values. Drop in temperature during work were statistically significant (P<0.05) compared to pre exposure. Occupational related health hazard – contact dermatitis, warts and block spot and blanching of fingers, palm and feet, might be attributed to the handling of ice cold water, fish and work environment. Majority of the workers (88%) had higher level total immunoglobulin E (IgE).

Machine design, job structure, physical and mental strain experienced by the operators of Computerised Numerical Control (CNC) machines were studied in an engineering company. Data were collected based on study of the machines, interviews and questionnaires. The main objective of this study is to investigate ergonomics, occupational health and safety problems of CNC machine operators. One hundred and twenty two employees participated in the study and different types of CNC machines were taken up for the study. The study revealed that 45 percent of the employees reported of lower back pain, 44% of neck, 21% of upper-body pain, 61% of shoulders and 41% of leg. However, the employees expressed that their jobs are more challenging and interesting. Furthermore, the environmental working conditions were assessed to be more convenient than in conventional workplaces. The outcome of this st...

Humans have limited power and require mechanization, to meet high energy demand, through equipment. We initiated this study to accumulate data from previous research to identify critical issues and approaches in implementing ergonomic principles into the design, intervention, development and assessment of manually operated equipment. Method. The literature search was carried out in scientific databases: Scopus and PubMed. Fifty-three research articles, meeting the inclusion criteria, were selected for this review. Results. The study indicated a propensity of countries with lower-middle-income and high-income groups, and of the agricultural and manufacturing sector toward research and development of manually operated equipment. A thorough study of the equipment design process revealed that health and safety was the prime motivator in the pre-design phase, an experimental prototype approach was most utilized in the design phase and a direct measurement technique was most frequently used in the post-design phase. Conclusion. The study highlights the scarcity of research in the integration of ergonomics into the design of manually operated equipment among countries with the low-income group. This study also promotes the use of virtual design and assessment techniques for cost-effectiveness.

The main objective of this study is to analyze subjective evaluation of musculoskeletal discomfort assessed by the forklift operators using the Cornell musculoskeletal discomfort questionnaire. A total of 47 operators aged between 20-58 years who are driving six types of forklifts in a heavy equipment manufacturing industry were selected for this study. The study revealed that forklift operators felt most of the musculoskeletal discomfort at lower back (65.45%) and in the neck (13.03%). Discomfort was less pronounced in the left upper arm (0.02%) and in the left lower leg (0.03%). Specifically, the results revealed that 40 out of 47 (85.11%) forklift operators sensed discomfort in the lower back 1-2 times per week; 41 out of 47 (87.23%) forklift operators reported discomfort was moderate and above. Because of this, 22 (46.8%) and 16 (34.04%) operators respectively have felt slight and substantial level of discomfort that has an effect on their ability to work.

Results: Neck discomfort due to the positioning of the machine displays, and shoulder and arm discomfort due to the positioning of controls were identifi ed as common health issues in the operators of these machines. The study revealed that 45.9% of machine operators reported discomfort in the lower back, 41.8% in the neck, 22.1% in the upper-back, 53.3% in the shoulder and arm, and 21.3% of the operators reported discomfort in the leg. Conclusion: Discomfort increased with the progress of the day and was highest at the end of a shift; subject age had no effect on patient tendency to experience discomfort levels.

There are some health and safety problems associated with these machine operations, however. The main objectives of the present work is to study the health and safety issues associated with the CNC machines with respect to control and display, specifically to determine the frequency, intensity of discomfort, and its interference in operating different CNC machines as reported by the workers operating them. The postural discomfort associated with CNC machines was studied, and the frequency, intensity of discomfort, and interference of the level of discomfort with the participants' ability to work were recorded and analyzed. The study revealed that 20.5% of the operators reported discomfort 1 or 2 times, 25.4% experienced discomfort 3 to 4 times in a week, 37.7% had discomfort daily, and 16.4% reported discomfort several times a day. Discomfort was reported in all the body parts involved (lower back, neck, upper back, shoulder, and leg), but the highest discomfort scores were associated with the shoulder and arm region. Workers reporting discomfort several times a day also reported high mean discomfort scores. The study established that the frequency and intensity of the discomfort in all body parts is related to the position of the control panel and display.
