The possibility of developing musculoskeletal disorders increases with the length of service of the worker. Musculoskeletal disorders can occur when performing repetitive and forceful movements. Therefore, Cargo drivers operate repeatedly in the wrong posture for a long time. When loading and unloading a cargo, the cargo driver works repeatedly with force. Cargo operators are also exposed to musculoskeletal disorders in the working environment due to poor posture and repetitive movements. In this study, we are going to conduct a study on the level of awareness and prevention of the possibility of musculoskeletal disorders in cargo drivers for long periods of time. As a result of the study, the factors that cause musculoskeletal disorders in each group can occur during the long-term operation and preparation of drivers.

A two-dimensional posture measurement system was developed to evaluate the risks of work-related musculoskeletal disorders(MSDs) easily on various conditions of work. The posture measurement system is an essential tool to analyze the workload for preventing work-related musculoskeletal disorders. Although several posture measurement systems have been developed for workload assessment, some restrictions in industry still exist because of its difficulty on measuring work postures. In this study, an image recognition algorithm was developed based on a neural network method to measure work posture. Each joint angle of human body was automatically measured from the recognized images through the algorithm, and the measurement system makes it possible to evaluate the risks of work-related musculoskeletal disorders easily on various working conditions. The validation test on upper body postures was carried out to examine the accuracy of the measured joint angle data from the system, and the results showed good measuring performance for each joint angle. The differences between the joint angles measured directly and the angles measured by posture measurement software were not statistically significant. It is expected that the result help to properly estimate physical workload and can be used as a postural analysis system to evaluate the risk of work-related musculoskeletal disorders in industry.

In 2003 the Korean Government introduced 'the risk factors analysis system' in order to prevent the work-related musculoskeletal disorders. In addition, the proclamation by the Ministry of Labor delineated eleven spheres of work associated with musculoskeletal disorders. According to Occupational Safety and Health Regulations, business proprietors who have workers engaged in tasks associated with musculoskeletal disorders are required to carry out a survey on risk factors every three years. Effective risk factors analysis principles and practices will succeed by refining the workplaces continuously. However, numerous difficulties arise during the application of risk factors analysis to the various industries. We discuss a number of issues related to risk factors analysis system, and suggest a number of directions for future work in this area.

The work-related musculoskeletal disorders have constantly increased since it became an issue in 1996. In 2002, the Government established the risk factors analysis system in order to prevent musculoskeletal disorders. The proclamation by the Ministry of Labor defined eleven spheres of work associated with musculoskeletal disorders. As a result, business proprietors, who have workers engaged in tasks associated with musculoskeletal disorders, are required to conduct the risk factor analysis on a regular basis every three years. However, numerous issues have been raised while carrying out the risk factor analysis in various industries. One of the issues is that even though work sampling is an ideal method in risk factor analysis, most cases have selected extreme task postures, which is judged by an expert, due to limited time. This study will propose the desired direction of the risk factor analysis by comparing task assessment results between work sampling scenes and extreme task scenes.

Musculoskeletal disorders show symptoms of pain and dysfunction caused by accumulation of minute damage on nerves and blood vessels which are related to specific body parts. This is more likely to occur in the elderly. In Korea, 40.3% of the agricultural population is over 65 years old. In these cases, the portion of musculoskeletal disorders is more than 80% in acute/chronic diseases related to agricultural work. Therefore, measures for physical health care and safety prevention of elderly farmers are needed. In this study, we intend to propose a method to measure musculoskeletal health condition through the motion recognition device and VR contents. For this, we analyze the agricultural work causing musculoskeletal disorders of farmers, and suggest a motion analysis algorithm that can measure the health condition of the musculoskeletal system. In addition, we are going to propose a training method customized for farmers on the basis of VR contents in order to prevent musculoskeletal disorders.

The presence of musculoskeletal burden tasks and work related musculoskeletal disorders (WMSDs) at Industrial workers was not well-known until 2000 in Korea. Since The Occupational Safety & Health Law was registered a business of proprietor duty in preventing work-related MSDs of workers In July of 2003 WMSDs became a big issue in Korea. A social previous interest was focused on the manufacturing industry just like auto and shipping industry in manufacturing sectors but nowadays it is spreading out to non-manufacturing fields gradually. Nevertheless, we have WMSD prevention Law and System in Korea to reduce WMSDs effectively and systematically we recognized some mistakes and problems of WMSD Law and System. In this paper we study these recent problems in Korea from about 10 years experience and proposed some proposals as discussion.

This study conducted two surveys to establish an educational system to prevent work-related musculoskeletal disorders. The first survey investigates the factors influencing the recognition of job specifications for risk factor analysts of work-related musculoskeletal disorders. The respondents of the first survey were selected from 173 different small-sized manufacturing enterprises having less than 300 workers and had experienced the inspection of risk factors. The results of the first survey shows that better recognition of job specifications are followed by the increase of education time, but regardless of the positions and periods of job experience. Among the respondents with a high level recognition, the second survey was conducted. According to the results, it is presented that 2, 8, 16 hours are the most suitable for educating workers, superintendents, and risk factors analysts. Based on the results of the second survey, educational contents have also been suggested. This research will provide the basic information when forming education systems to prevent musculoskeletal disorders.
