This paper describes a practical ergonomic approach for the shipbuilding industry that occupies the highest rate of work-related musculoskeletal disorders (WMSD) in Korea. Typical work processes within a shipbuilding operation were surveyed to determine the presence of risk factors associated with musculoskeletal disorders. We used interviews, document analysis, video analysis, and OWAS postural analysis to identify and quantify ergonomic risk factors that workers may be exposed to in the course of their normal work duties. Some ergonomics actions were performed to solve the problems identified in the risk factor analysis. The practical ergonomic approach has resulted in decreases in workers' accident, and increases in productivity. The ergonomic solutions developed in this study could be applied to other sectors of industry that share common features of work with shipbuilding industry.

Objective: The goal of this study was to assess work ability of Korean workers in the shipbuilding industry. Background: Old age is associated with inevitable time-dependent losses in physical capabilities. However the maintenance of physical capabilities is essential for continuing independence in old age. The work ability index(WAI) was constructed to reveal how well a worker is able to perform his or her work. Method: The WAI is a kind of survey methods developed to estimate the work capacity of aged workers by the Finish Institute of Occupational Health(FIOH) in 1998. The difference of the WAI between groups in each category was tested using the Kruskal-Wallis test, and the relationship between the WAI and the workers' ages was tested by the Correlation test. Results: This study surveyed 2,709 persons working in the shipbuilding industry in Korea. The average WAI score for all workers was 40.0 denoting a Good Level. Also, workers in the shipbuilding industry had lower work ability, as compared to the results of other industries. The WAI was analyzed for different age groups(${\leq}29$; 30~34; 35~39; 40~44; 45~49; 50~54; ${\geq}55$). The results of Kruskal-Wallis test showed that significant difference was identified on the effect of aging(p<0.05). Conclusion: Advanced countries like the Finland showed decreasing tendency in good and excellent levels as aged, but there was no decreasing tendency in Korean population. The results may be attributable to the general characteristics of Korean society, such as poor social security and burden caused by role of the patriarch. It may bring forth higher work ability in aged population even their physical condition is getting worse. Application: This finding could be used for developing more accurate assessment tool of work ability for working environment.

This study examined the wearing conditions of working clothes of shipbuilding industry workers according to the working environmental factors and working process features. It was also investigated the relationship between the wearing sense of working clothes and the overall comfort according to work processes. In the working process of shipbuilding industry, the process of fitting, welding, grinding and painting were chosen by considering work environmental factors, disaster types, hazardous materials, work process features, working clothes and safety equipments of each work categorized. The workers of fitting process usually wore the standard working clothes, while more than 60% of the workers of welding, grinding and painting wore the specialized protective clothes. The hazardous work environmental factors such as noise, heavy dust, high temperature and noxious fumes affected to the workers of fitting, welding and grinding. However, the workers of painting were greatly damaged by organic solvent. The dissatisfaction with the wearing performance of working clothes was highly shown in the sweat absorbency, moisture permeability and body protection. In respect of the correlation between the overall comfort and the wearing sense of working clothes, the satisfaction was decreased in orders of movement comfort> sensual comfort> physiological comfort.

Korea's shipbuilding industry has led the world in the technical area over the last century. Despite this commendable performance, around 2,000 workers experience accidents almost every year with 40 being killed. This raises a question of whether the safety level of our shipbuilding industry, in particular the safety of workers, is actually at the world-class level. Accordingly, this research has analyzed several types of safety training currently provided in the field through investigating statistical data of serious accidents occurring from 2006 to 2015 in the domestic shipbuilding industry, analyzing its occurrence and causes, and conducting a survey targeting employees in the shipbuilding industry. Based on this, it has investigated problems of safety training in the shipbuilding industry and suggested improvements. First, it is essential to create a standard system for safety training in the shipbuilding industry to address problems of different kinds and levels of safety training provided by each shipyard and low quality of training, and operate more organized and systemized training. Second, safety training curriculum specializing in the shipbuilding industry should continue to be developed and standardized based on a standard system for safe training to prevent serious accidents and improve safety awareness of workers. Lastly, both employers and employees should actively provide and participate in safety training to secure safety of workers through preventing serious accidents and ultimately create safety-first culture in workplace.

In recent years, Korea's shipbuilding industry have expanded its business into offshore plant. These changes are increasing the interest on job stress in shipbuilding industry. The purpose of this study is to investigate the differences of job stressors between white and blue-collar workers. The survey was using Korean Occupational Stress Scale(KOSS) questionnaire and was administered to 8,080 workers of large shipyard company. As a result of the survey, compared with the median score of Korean workers, job stress level of shipyard company workers was low. However, seven categories of KOSS, except for job demand showed higher stress levels of blue-collar workers than white-collar workers. The overall stress level of shipyard company workers is low, however, it is important to find stressors by considering the type of work, working period etc., through a detailed analysis of KOSS 8-categories. The results of this study may be helpful to identify the level of stress and to establish preventive measures in Shipyard Company.
