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.

The objective of this research is to select the most effective technique among task related techniques(motion & time study, job redesign, physical environment improvement) for improving work efficiency in shipbuilding enterprise. This study consists of several principal steps. The first step is to design critical criteria in evaluating work efficiency in ship-building enterprises. The second step is to develop sub-criteria of the critical criteria. The third step is to develop a four level AHP(Analytic Hierarchy Process) structure using the critical criteria, sub-criteria and techniques among task related techniques. The fourth step is to develop the pairwise comparison matrix at each level of AHP structure, which was based on survey data collected at the H heavy industry. And the last step is to select the most effective technique among task related techniques using AHP analysis. The result of AHP analysis has shown clear difference in priority among task related techniques in terms of work efficiency of the shipbuilding enterprise: The reduction of normal time is more important than the reduction of allowance time in improving of the work efficiency. Motion & time study is the most important technique for the reduction of normal time, and physical environment improvement is the most important technique for the reduction of allowance time as well.

The shipbuilding industry is characterized by order production, and various processes are performed simultaneously in the construction of ships. Therefore, effective management of the production process and productivity improvement form important key factors in the industry. For decades, researchers and process managers have attempted to improve processes by using business process analysis (BPA). However, conventional BPA is time-consuming, expensive, and mainly based on subjective results generated by employees, which may not always correspond to the actual conditions. This paper proposes a method to improve the production process of offshore plant modules by analysing the process mining data obtained from the shipbuilding industry. Process mining uses information accumulated from the system-provided event logs to generate a process model and determine the values hidden within the process. The discovered process is visualized as a process model. Subsequently, alternatives are proposed by brainstorming problems (such as bottlenecks or idle time) in the process. The results of this study can aid in productivity improvement (idle time or bottleneck reduction in the production process) in conjunction with a six-sigma technique or ERP system. In future, it is necessary to study the standardization of the module production processes and development of the process monitoring system.

The Korean marine equipment industry is, in significant ways, behind the shipbuilding industry. For example, in terms of the number of orders received, the shipbuilding industry has ranked first in the world since 2003. In contrast, the global competitiveness of Korea's marine equipment industry is still relatively weak. This is important not only for the equipment industry, but because these two industries have many links. The structure of this research was firstly, to identify theoretical issues by looking at the characteristics of the marine equipment companies, marketing recognition, uses of marketing, and financial outcomes. Second, the study developed an analytical framework for empirical examination using configuration of each factor. Third, each factor has been analysed empirically. Forth, this study presents the importance of marketing for marine equipment companies within Korea, as well as in a global market. Finally, the study suggests a new marketing strategy for Korea's marine equipment companies to achieve global competitiveness.

International Organization for Standardization has recently published ISO 9001:2008 which is the basic requirements for a quality management system that an organization must fulfil to demonstrate its ability to consistently provide products that enhance customer satisfaction and meet applicable statutory and regulatory requirements. Not many empirical researches based on ISO 9001:2008 have been done up until now. In this article we outline transitional features for ISO 9000 quality management system (QMS) since its first publication in 1987. In order to effectively maintain ISO 9001:2008 QMS certification and continuously enhance quality management activities, we perform statistical analysis for the minor nonconformity data generated from follow-up audits for subcontractors of shipbuilding industry based on ISO 9001:2008 requirements. A Kruskal-Wallis test is used to show relationships between the minor nonconformity data and three classification criteria: the type of business, the size of business, and the number of follow-up audits.

This paper aims to provide basic data for work environment control, prevention of worker exposure to asbestos and improvement of air quality to protect workers ‘health after measuring the level of airborne asbestos and workers' exposure in a shipbuilding repair businesses. For this study, a total of 27 samples were collected from 27 workers who had been exposed to asbestos during engine, piping, boiler and other manufacturing processes in 'A' Shipbuilding Repair Company in Gyeongnam. This research was conducted from Oct. 1 to 30, 2007 and had the following results: The target group (27 workers) consisted of all men with an average age of 35.9 years and 6.6 years of work on average. Among them, fifteen 15 (55.6%) were smokers. In terms of their duties at work, there were 12 plumbing repair engineers (44.4%), 8 boiler repair engineers (29.6%) and 7 engine engineers (25.9%). The geometric mean concentration of airborne asbestos was 0.004 f/cc. A total of 4 samples exceeded the exposure limit. In particular, three exceeded the legal limit by more than double, which means that some workers have been highly exposed to asbestos. In terms of the concentration of asbestos fibres by work process, plumbing repair was the highest (0.0071 f/cc($0.001{\sim}0.57\;f/cc$)) while boiler was the lowest (0.0015 f/cc($0.001{\sim}0.007\;f/cc$)). Based on this study, proper action needs to be taken as soon as possible to protect workers from the threat of asbestos.
