Purpose: This study was conducted to analyze the characteristics of work-related musculoskeletal diseases (MSD) and the factors for approving MSD by the parts of the body. Methods: The analysis was done using the data which were drawn from the Industrial Accident Compensation Insurance that is operated by the Korea Worker's Compensation & Welfare Service. The data were composed of total cases related to the work-related diseases from 2006 to 2009. In addition, MSD data input by an investigator were collected. The factors associated with MSD were analyzed using ${\times}2$ and multiple logistic regression. Results: MSD approved cases have increased since 2006 and the proportion of the approved work-related MSD cases in the workers with work-related diseases in 2009 were 33.4%. Spinal approved cases were the highest percentage and upper and lower extremities cases gradually increased. The factors for approving upper extremity were found to be age, company size, type of industry, working duration, and in the case of spine to be company size and heavy lifting. Conclusion: Work-related MSD have increased and the factors that affected MSD by the parts of the body varied. Management strategy must be established to prevent MSD by the parts of the body.

Compared to other occupations, there is a greater risk of exposure to radiation due to the use of radioisotopes in nuclear medicine for diagnostic evaluations and therapy. To consider ways to reduce exposure dose for those in nuclear medicine involved in injection work and elution work among radiation workers as well as for sanitation workers and trainees among frequent workers an investigation into exposure dose and situational analysis from changes in yearly exposure dose evaluations, changes in work environment and changes in forms of inspection were conducted. Exposure dose measurements were taken by using EPD MK2 worn during working hours for one injection worker, one elution worker, two sanitation workers, and one trainee at a general hospital in the Seoul area for three days from July 18th to 20th 2016. Radiation from radioisotopes which are a part of nuclear medicine can significantly affect not only radiation workers who deal with radioisotopes directly but also frequency works as well. According to this study the annual dose limit for elution workers and injection workers were considered safe as the amount of exposure was not large enough to have a significant effect. The limits of this study consist in the duration of this study and the quantity of participants. Also there was a limitation of the measurement device involving accumulated exposure, where the EPD MK2 cannot check the changes in exposure according to a particular activity.

As railroad industry faces the new Renaissance era, effective and efficient maintenance methods for rolling stock operation are required with advanced railroad technology. All kinds of railroad systems such as high-speed long-distance train, metropolitan mass transit and light rail require systematic maintenance technology in order to maintain the safe railroad operation. Simulation models for regular operations of the example maintenance center are developed. In this study, standard maintenance procedures, layout, equipments, and number of workers of Siheung Metropolitan Railroad Maintenance Rolling Stock Depot are considered. The proposed simulation models are developed using simulation package ARENA. After simulation, four types of observations are analyzed. First, the bottleneck operation is identified. Second, the relationship between maintenance center size, number of workers and cycle time is analyzed. Third, the scheduling performances between PERT/CPM and Critical Chain Project Management(CCPM) are compared. Lastly, the simulation results according to worker's working coverage shows expanding the worker's coverage decreases the cycle time and increases throughput per train. However, workers are to be fully trained to do multiple skill work.

Education has recently witnessed a rapid increase in the use of edutech worldwide. This study focuses on Korean workers and explores an edutech-based learning model for vocational education and training. Based on analyses of edutech cases and interviews with edutech experts, a draft edutech model was designed and the validity was evaluated based on two Delphi surveys with a panel of experts in the field. The study's findings suggest that edutech-based employee education and training should prioritize LXP orientation (last CVR=1, last Mean=4.70) , implement adaptive learning through learning analytics (last CVR=1, last Mean=4.90), enhance the human touch effect using edutech (last CVR=1, last Mean=4.90), and emphasize the importance of designing curricula that apply edutech in a step-by-step learning process while incorporating suitable instructional design for the key technologies involved in vocational training programs. In addition, it was revealed that there is a strong need to implement a method that makes each stage of the learning process more effective (before, during, and after). Edutech-based vocational training program should consider the interests of all stakeholders, including learners, instructors, vocational training institutions, and government agencies. Given the promotion of government-sponsored vocational training projects in Korea, the findings of this research are likely to have significant implications for the future of Korea's education and training policies.

Musculoskeletal disorders(MSDs) are one of the major issues in shipbuilding industry. Main risk factors of MSDs include manual handling of heavy weight, awkward posture, repetitive tasks, prolonged static muscle contraction, and so on. in this study, Using the three-dimensional digital human modeling and simulation method we made up a worker and work posture on a virtual environment. To verify this simulation we compared both traditional ergonomic analysis on a real worker and digital program analysis on a digital human. And this paper shows that it is possible to reduce the rate of MSDs in the shipbuilding industry because it means we can change poor posture mid surroundings into better ones.

When picking up cargo, workers manually load and unload the cargo. Workers have different intensity of work depending on the amount and weight of cargo. In particular, as the intensity of manual work increases, workers are exposed to cumulative traumatic diseases. A manual for picking safety work for workers cargo handling in the distribution center is required. In this study, the worker's picking safety work based on the cargo volume and weight was presented as an experimental design model. Like the research results, the disease begins when the worker feels the number of pains presented by the model.

This study was conducted to use the feedback of health personnel to improve the Visiting Health Service. The data was collected from 471 Home Health Workers serving 24 local health organizations in the Kyung-Pook province. 62.5% of the respondents were men under thirty-nine years of age. 92.8% of the respondents are married. 47.1% had degrees from junior colleges. It was ascertained 52.7% of the workers visited their patients six to twelve times within a six month period. And one to three patients were visited per day by one worker. Workers of older age, higher job position, and more experience were more positive in their feedback about the program. In addition, local health center employees, including nurses, were more positive about the program. Younger workers with a higher level of education, less experience, and lower job position had more insight into the problems of the program. Deeper insight into these problems led to a more negative conception of the program. Older workers with higher ranking jobs were found to be most competent. in their jobs. Workers at the main health center were assessed higher than the workers at the health sub-center or the primary health post. In addison nurses at all centers were found to be slightly more competent than the nurses' aide. The primary health post established the highest degree of patient satisfaction. It was discovered that the more positive the workers felt about the program, the higher their patient satisfaction feedback. There was a positive correlation between management assessment and patient satisfaction. This means that better program management was found to produce higher patient satisfaction. Workers feel being more educated about patient management would lead to better service. However, they take no action to produce these results. Where the problems of the system are most commented upon, the need for further education is greatest. Through multiple regression analyses it is apparent that the assessment of patient management is the greatest variable affecting patient satisfaction of patients is dependent on the management by the visiting health worker. Therefore, the development of the visiting health program is highly dependant on the feedback of those workers with a negative conception of the program. So the development of programs, motivation, education and training must be established. These works would lead to active participation by visiting health workers in the improvement of the Visiting health program.
