Economic burden of work-related musculoskeletal disorder(WMDs) is increasing. Known causes of WMDs include improper posture, repetition, load, and temperature of workplace. Among them, improper postures play an important role. A smart sensor called SensorTag is employed to estimate the trunk postures including flexion-extension, lateral bend, and the trunk rotational speeds. Measuring gravitational acceleration vector in the smart sensor along the tri-orthogonal axes offers an orientation of the object with the smart sensor attached to. The smart sensor is light in weight and has small form factor, making it an ideal wearable sensor for body posture measurement. Measured data from the smart senor is wirelessly transferred for analysis to a smartphone which has enough computing power, data storage and internet-connectivity, removing need for additional hardware for data post-processing. Based on the estimated body postures, WMDs risks can be conviently gauged by using existing WMDs risk assesment methods such as OWAS, RULA, REBA, etc.

A 3D camera-based on-site work-related musculoskeletal disorder risk assessment(WMDs) tool has been developed. The device consists of Kinect a 3D camera manufactured by Microsoft, a servo-motor, and a mobile robot. To complement inherent narrow field of view(FOV) of Kinect, Kinect is rotated according to PID servo-control algorithm by a servo-motor attached underneath, to track movement of a subject, producing skeleton-based motion data. With servo-control, full 360 degrees tracking of a test subject is possible by single Kinect. It was found from experimental tests that the proposed device can be successfully employed for on-site WMDs risk assessing tool.

Objectives: A rapid increase in the population of migrant workers in Korea has brought new challenges regarding the possible effects of acculturation on health. The purpose of this study was to examine the influence of acculturation- and work-related psychosocial factors on work-related musculoskeletal disorders among migrant female workers living in Korea. Methods: A cross-sectional survey design was used. A translated, structured questionnaire was administrated to 156 southeastern Asian female full-time workers living in Korea. Results: About 35% of the participants experienced some type(s) of work-related musculoskeletal disorder(s), which were more prevalent in Vietnamese women than in Thai and Filipino women. Women who preferred to maintain their own heritage and to reject the host country heritage were at risk for work-related musculoskeletal disorders. Conclusion: Acculturation strategy and nationality were found to be significant factors associated with work-related musculoskeletal disorders. Health professionals need to accommodate acculturation contexts into risk assessment and intervention development for work-related musculoskeletal disorders separately for different nationalities.

Objective: This study was performed to investigate the prevalence of musculoskeletal disorders in auto workers of a mission assembly plants. Background: Most studies of musculoskeletal disorders have used car assembly line workers as their participants. However, little research has been done on musculoskeletal disorders afflictions of mission assembly line workers. Method: Through a focus group interview with an ergonomist and a manager at a mission assembly plant site, a questionnaire was developed for musculoskeletal disorders. The questionnaire consisted of five parts, demographic factors, musculoskeletal disorder symptoms, and musculoskeletal disorder experiences; 137 workers participated in this survey. The surveys were analyzed by correlation and Chi-squared analysis. Results: Musculoskeletal disorder symptoms and serious pain were reported in the neck, shoulder, back, and fingers. These problems were statistically related to various demographic factors, such as age, stature, stretching, and work satisfaction. Conclusion: Treatment of musculoskeletal disorders should consider the workers' traits. If there is no specific cause of the pain, developing stretches and exercises before and after work should be applied to prevent musculoskeletal disorders. Application: The results of this study can be used to develop guidelines to prevent injury in auto workers at mission assembly plants.

Purpose: The purpose of this study was to investigate the prevalence and affecting factors of work-related musculoskeletal disorder (WRMSD) among the directory assistance operators. Methods: One hundred eighty-five female subjects who worked more than one year as directory assistance operators in a telecommunication company were surveyed with self-administered questionnaires. Subjects were divided into disorder and control group by the NIOSH criterion about WRMSD, and then analyzed. Results: One hundred seventy two subjects (93%) had upper extremity symptoms and seventy subjects (37.8%) were WRMSD. the frequency order of the disorder area was the shoulder 60(32.4%), the neck 37(20.0%), the wrist 20(10.8%), the finger 20(10.8%) and the elbow 5(2.7%). It was found that the difference factors of the WRMSD group were education level (p<0.01), stress from the customers (p<0.01), satisfaction about monitor (p<0.05), temperature (p<0.05), noise (p<0.01), ventilation (p<0.001), working time (p<0.05), and recess (p<0.001). Conclusion: Improving working condition and education for the workers to control the stress are necessary to decrease the WRMSD for the directory assistance operators.

Background: To investigate the relationship between musculoskeletal disorders and comorbid health problems, including depression/anxiety disorder, insomnia/sleep disorder, fatigue, and injury by accident, and to determine whether certain physical and psychological factors reduce comorbid health problems. Methods: In total, 29,711 employees were selected from respondents of the Third Korean Working Conditions Survey and categorized into two groups: Musculoskeletal Complaints or Musculoskeletal Sickness Absence. Four self-reported health indicators (overall fatigue, depression/anxiety, insomnia/sleep disorder, and injury by accident) were selected as outcomes, based on their high prevalence in Korea. We used multiple logistic regression analysis to determine the relationship between comorbid health problems, musculoskeletal complaints, and sickness absence. Results: The prevalence of musculoskeletal complaints and musculoskeletal sickness absence due to muscular pain was 32.26% and 0.59%, respectively. Compared to the reference group, depression/anxiety disorder and overall fatigue were 5.2-6.1 times more prevalent in the Musculoskeletal Complaints Group and insomnia/sleep disorder and injury by accident were 7.6-11.0 times more prevalent in the Sickness Absence Group. When adjusted for individual and work-related physical factors, prevalence of all four comorbid health problems were slightly decreased in both groups. Conclusion: Increases in overall fatigue and depression/anxiety disorder were observed in the Musculoskeletal Complaints Group, while increases in insomnia/sleep disorder and injury by accident were observed in the Sickness Absence Group. For management of musculoskeletal complaints and sickness absence in the workplace, differences in health problems between employees with musculoskeletal complaints and those with sickness absence as well as the physical and psychological risk factors should be considered.
