Prevalence and risk factors of musculoskeletal disorders among Myanmar migrant workers in Thai seafood industries

Soe K. T., Laosee O., Limsatchapanich S., Rattanapan C.

International Journal of Occupational Safety and Ergonomics

2015

Vol. 21, No. 4

539--546

A cross-sectional descriptive study was conducted with self-administered questionnaires among 368 Myanmar migrant workers to investigate the prevalence of and to determine the risk factors for musculoskeletal disorders (MSDs) in the Thai seafood industry. The results showed the prevalence of MSDs was 45.1% occurring in the last 7 days. Marital status, number of dependents, other health problems, working hours, repetitive hand movements, awkward posture of wrists, prolonged standing, and manual handling of heavy loads were found to be associated with MSDs. Multiple logistic regression indicated that the workers who were married, had more than two dependents, and had more exposure to awkward wrist postures were at significantly increased risk of MSDs. The study findings suggest the need for adequate knowledge of ergonomics and for awareness campaign programs focusing on prevention of MSDs, especially low back pain, to be initiated in industries for earlier detection of symptoms among seafood processing workers.

Evaluation Copper Smelting Process in a Fluidized Bed Furnace Based on the Analysis of a Vibroacoustic Signal's Envelope

Mączak J., Radkowski S.

Machine Dynamics Problems

2008

Vol. 32, No. 4

67-77

Preventive maintenance procedure is presented to improve the copper smelting process in "blister" furnace. It was shown that the process could be more efficient by applying periodic monitoring to avoid the state of "slag boiling". In the paper the algorithm of diagnostic information selection was proposed allowing for application of condition-based maintenance making the smelting process more effective
