Importance of the work-related musculoskeletal disorders(WMSDs) has been increasing in the manufacturing industry such as the domestic shipbuilding industry and car industry. Recently, companies have implemented the risk factor investigation due to the amendment of the industrial safety and health law in 2003. At the same time, some large companies have introduced and implemented an ergonomics program for WMSDs. Yet, until now a study of the effect and management of the ergonomics program has not been conducted. In 2005, we audited an ergonomics program in a domestic shipbuilding company four times for 9-month period. The company implemented an ergonomics program from 2003 to 2005. From the investigation, this paper reveals the effects and problems of the ergonomics program implemented by the company and presents methods for its improvement. The findings described in this paper will help the companies to implement their ergonomics program for WMSDs in the future.

Environment of marine transportation market is changing rapidly. Due to globalization of world economy, marine transportation of cargos, especially trade using container boxes, is increasing dramatically. Fierce competition in the global market of container transportation forces the shipping industry to seek the economy of scale to reduce transportation cost, and drives the merge and alliance of liner shipping companies. Mega-sized container ships, having capacity over 10,000 TEU, were introduced, and appeared recently, in order to reduce the unit transportation cost. Korean shipping and shipbuilding companies are competitive, and have considerable market share in the global market. Even though both industries are inter-connected through ships and have many common interests in order to enlarge the global market share, inter-relation between two industries is surprisingly insignificant. In this paper current issues in the process of environmental change of marine cargo transportation are reviewed, and inter-relation of shipping and shipbuilding industries is discussed. Suggestions for inter-related development of Korean shipping and shipbuilding industries are given, and means for mutually beneficial collaboration are suggested.

This paper investigated the impact of economic cycles in the shipbuilding industry on managerial performance of marine paint and coatings firms. As part of the upstream to ship construction, the marine equipment industry plays a critical role in determining the competitiveness of the shipbuilding industry. Despite a close interaction between the two sectors, the majority of research on the marine equipment industry has highlighted securing competitiveness edge and developing advanced technologies, paying little academic attention to the relationship between shipbuilding and managerial performance. In this regard, this paper examined how economic cycles in shipbuilding affected growth and profitability of marine paint and coatings firms. To this end, managerial performances of six marine paint and coatings firms for the period of 2003-2022 were analyzed in panel regressions. Results indicated that the shipbuilding economic cycle proxied by delivery amounts of Korean shipyards was positively associated with growth and profitability of marine paint and coatings firms. However, there was divergence in statistical significance by shipbuilding indicators. While coefficients of compensated gross tonnage, gross tonnage, and monetary amount were statistically significant, that of deadweight tonnage was not. Findings of this study imply that managerial performances of marine paint and coatings firms are affected by the amount of value added from the shipbuilding industry rather than its absolute size.

According to the Korea National Statistical Office data in 2010, the population over ages of 65 years would possess to 11.3% whole population of Korea in 2011 denoting Korea is already in the aging society. 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 work. This study focused on the discovery of an industrial and age-related influences on the work ability and job stress of workers in the shipbuilding, house managing, apartment construction industry. For this, the study conducted a job stress test using the Korean Occupational Stress Questionnaire Short Form, and employee performance evaluations using the Work Ability Index (WAI) of the Finnish Institute of Occupational Health (FIOH) on 3,228 workers in the shipbuilding, house managing and apartment construction industry. SPSS 12.0 K statistics program was used for statistics analysis and significance was verified with the Kruskal-Wallis test, a corporate body of nonparametric statistical analysis. As a result, employee performance had significant differences, depending on age, an industrial and years of service. The mean WAI score of the shipbuilding industry was lower than that of the other industry. Additionally, it was found that employee work ability decreased more as job stress increased.

This paper aims to explore the spatial distribution and locational characteristics of the shipbuilding industry in the south-east region of Korea. The geography of the Korea's shipbuilding industry illustrates an absolute spatial concentration into the south-east region, including Gyeongnam, Busan and Ulsan. In view of the type of agglomeration, it is argued that the south-east region's shipbuilding industry has been evolved as an Advanced Hub & Spoke cluster, which is characterized by interconnected relationships between a couple of gigantic customer firms and the majority of small and medium-sized supplier firms. A survey on the locational factors of the firms presents that traditional locational factors, such as physical infrastructure, land, labour and industrial linkages, are more important than new economic geographical locational factors, such as knowledge, learning, innovation and networks. According to firm's evaluation of the Gyeongnam region's locational environments for the shipbuilding industry is, however, rather different to the result of firm's location decision factors. The shipbuilding firms in Gyeongnam see that the Gyeongnam region retains regional advantages in terms of agglomeration economies, geographical proximity to customers, the infrastructure of transportation and communication and the quality of life. On the contrary, firms recognize that the Gyeongnam region suffers from the lack of R&D and production workforce and a weak basis of industry-university -government networks.

Pay-for-performance plans are some of widely used human resource practices in many firms, including shipbuilding, for productivity and motivational improvement purposes. Such plans play an important role in industries that are highly labor-intensive, and where effective management of human resources is critical to business operations, such as the shipbuilding industry. Those practices can have large impact on employee performance and ultimately company competitiveness. Research studies that show how such incentive plans improve productivity and reported pattern of adoption by firms have spurred the use and adoption in many firms. However, there are also researchers who point out that there are negative consequences to using incentive plans. Therefore it is important for companies to carefully consider the practices they use. In this paper, I discuss research findings that support the practices and critical viewpoints related to pay-for-performance plans. Research findings from Korean literature are, then, discussed. The shipbuilding industry is chosen because proper human resource management is critical in reducing turnover and increasing employee satisfaction. Through a shipbuilding company case, problems related to using pay-for-performance incentive plans and how they affect work-related issues of employee morale, cooperation, and teamwork will be discussed. While positive aspects have been emphasized to drive greater adoption among firms, the resulting consequences of the pay plans need to be seriously considered and improvements upon the plans made by firms. Improvement suggestions are discussed in the conclusions and implications.

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.

A method of three-dimensional curved surface generation was studied for multi-point dieless forming (MPDF) in the shipbuilding industry. Three-dimensional coordinates of punch elements were obtained from objective surfaces using a proprietary CAD program. MPDF surfaces were generated by adjusting the height of punch elements in accordance with the coordinates. Some problems, such as collision of punch elements and contact between plates and punch bodies, were anticipated from the analysis of the results. A twisted surface was formed successfully by MPDF in a laboratory scale, which suggests possibility of application of the technology to the shipbuilding industry.

The influence of wave forces on the moored ship beside quay was investigated based on in-house ship mooring analysis and ship motion program in this paper. The wind and current are the general environmental factors for the mooring analysis beside quay in the mild weather. However, the weather is becoming rough, the wave phenomenon should be included in the mooring analysis. In this paper, as preliminary stages, each moored rope tension was evaluated based on wind and current environmental condition. The results were compared with those from MOSES, commercial program. In addition to this, wave forces of the ship were calculated in order to solve moored ship motion of equation. We will leave to solve this motion equation as future work.

This study inquired the features of restructuring of shipbuilding industry and structure of community cooperation. The Sinhyeon-eup region has experienced rapid changes as a large shipyard location. Prior to Korea, Japan has developed the cooperation of company-community-residents relationships and the reorganization of location systems through division and accumulation system. The restructuring of shipbuilding industry in Korea have focused on the improvement of business environment. So they have not been efficiently settled in the accumulation and the cooperation structure between company and region. Japan established the organic cooperation structure of company and community before the large restructuring, while the shipbuilding industry city of our country commenced it with the crisis of community by the restructuring. In the Sinhyeon-eup region, The connecting ring among the production sections of a core company in center is established. However the structure of community cooperation is weak. The structure of community cooperation as local governance consist of company, pubic institution, local residents, and regional expert. This structure can be a rational channel in which it can not only strengthen the cohesion of the community, but also solve the present questions of the industrial city.
