The purpose of this study is to analyze the industrial structural changes and types of specialized in the shipbuilding cities, which are representative sectors of industrial city decline, and explore regional responses. Most cities designated as special areas for industrial crisis response in 2018 are specialized in shipbuilding. While the shift from prosperity to recession since the 2010s is the main factor, each city has responded differently to the industrial crisis. The analysis, targeting seven shipbuilding cities, shows that regions where large shipyards of major corporations with high industrial competitiveness are located have relatively less decline during business fluctuations, and there is a tendency for a decrease in industrial structural diversity during prosperous periods and an increase during recessionary periods. Based on the resistance and recoverability to industrial crises, the industrial paths of shipbuilding cities are classified into four types. Considering regional industrial structure and competitiveness, it is necessary to develop customized support strategies such as maintaining and declining shipbuilding industries and fostering new alternative industries.

The productivity improvement is indispensible to shipbuilding industry for maintaining the world's No. 1. Simulation based production recently has been an issue as prat of efforts to high efficiency production and Korean shipyards requests simulation system tools specialized in a shipbuilding industry. IT convergence project between conventional shipbuilding industry and IT simulation technology has been carried out and integrated simulation framework was proposed as a way to overcome sporadic developments. The framework would provide reusability of kernels and modules and also ensure for expansibilities to other production simulations. The fact that production simulation system should reflect shipyard requirement would be most important. We suggest an analysis process of customer requirements and functional requirements for production simulations. It is partially based on concepts of software engineering and axiomatic design. The process is applied to a design of configuration for simulation framework.

According to the Korea National Statistical Office data in 2008, the population over ages of 65 years would possess to 10.7% whole population of Korea in 2009 denoting Korea is already in the aging society. In addition, the office also expected that Korea would enter in the aged population over 65 years: 14.3% and post-aged 20.8% society in 2019 and 2026 respectively, and which suggests that an averaged age of workers in Korean industries may increase rapidly in future. The main purpose of this study is to assess the work ability and the job stress of each age group in order to identity the influential factors on those items. To this end, Questionnaires about work ability and job stress were distributed to practitioners in shipbuilding industry and statistical analysis was performed to assess work ability and the job stress based on the responses from the practitioners.

This paper draws implications on the ship finance of the Korean ECAs for shipbuilding industry from the perspective of WTO ASCM through studying the trade disputes on export credits. In consideration of the underwriting practice on the case-by-case basis, the ECAs' law regimes and their ship finance programs as such would be judged not conferring a benefit. The ship finance of international commercial banks could be treated as a market benchmark for the purpose of determining the existence of benefit in the ECA ship finance. The ECAs share securities with international commercial banks for the same exposure to the risks in a syndicate. Therefore, WTO DSB would rule that the ECA ship finance confers no benefit for individual transactions. The items (j) and (k-1) of ASCM Annex I are not allowed to interpret a contrario.

Generally, the shipbuilding industry has finite resources and limited workspace. Due to finite resources, limited workspace and state of block preparation, erection process in shipbuilding industry is frequently delayed than erection process scheduling which is planned at long-term plan stage. In this study, considering variability of block reserve ratio, the degree of delay in real erection process is measured and compared to scheduling which is planned at long-term plan stage in shipbuilding industry including finite capacity and variative lead time. Also, the erection process scheduling which has minimum lead time can be checked through simulation. The results of this study could be improved the accuracy of erection process scheduling by checking the main event compliance ratio by block reserve ratio and calculating the optimum erection pitch for the main event compliance.

As the government encourages the replacement of small FRP ships with eco-friendly aluminum ships due to environmental pollution problems, interest and demand for small aluminum ships are increasing. It is known that the vibration and noise of aluminum ships are somewhat vulnerable than that of FRP ships. However, in the process of designing and manufacturing small aluminum fishing boats, vibration and noise are not reviewed. In this study, vibration analysis is performed on three existing aluminum fishing boats, and the vibration characteristics of small aluminum boats are identified. Through this study, we intend to contribute to improving the vibration quality of small aluminum ships.

As ships become larger and construction of offshore plants increases recently, the amount of outsourcing has increased accordingly in the shipyard. Consequently, the system integration in terms of SCM (Supply Chain Management) of information and material flows has become much more important. Especially, since the SCM in the shipbuilding industry is operated in accordance with the production planning in connection with design, purchasing and production process which are the main components of the supply chain, the best production plan has to be established over the whole scheduling activities from the long-term planning to the short-term planning. The paper analyzes the characteristics of the SCM and the production planning system and suggests the need and the direction of APS (Advanced Planning System) development specialized in the supply chain management only for shipbuilding industry. Furthermore, propose a new SCP-Matrix (Supply Chain Planning Matrix), which is the basis of the APS development, appropriate for the shipbuilding industry and draw the core function of the APS module for the practical production plan.

Information technologies centered on the internet in the area of shipbuilding and marine engineering further incur the needs to increase the flexibility of the organization, the dispersion of work process, and the use of out sourcing, as well as the globalization of related market. In near future, electronic commerce and concurrent engineering based on CALS/EC and the Internet will be an integral part of the environment and upon these changes, ship design and construction will become a computer supported cooperative work of many dispersed and specialized groups. As the means of active response to these environmental changes, many new concepts such as digital shipbuilding, virtual shipyard, and simulation based design are appearing. In this paper, the concept and current status of digital manufacturing in general manufacturing industry will be reviewed. Then, related technologies, area of application and methods of digital manufacturing in shipbuilding and marine industries are presented. In addition, virtual assembly simulation system for shipbuilding(VASSS), a tool for crane operability and block erection simulation in virtual dock based on 3D product model, will be introduced.

It is true that every country which includes the developing country has planned own economic development through government subsidies. Korea also has developed their some major industry through supporting government subsidies. Under the WTO structure, however, government's specific supports for export firms come under prohibited subsidy and subsidy supporting must be based on WTO ASCM(Agreement on Subsidies and Countervailing Measures). The purpose of this paper was to study on the WTO ASCM and to analyze cases on the shipbuilding and Hynix DRAM dispute which Korean concerned major subsidy issue. Korea has been undergoing subsidy dispute with EU and U.S.A. concerned matter of shipbuilding and Hynix DRAM respectively. From this research results were as follow : First of all, the WTO ASCM introduced a definition of subsidy and divided subsidies into three categories and was legally bound through dispute settlement mechanism and implemented by all WTO members. Also, through analyzing cases, results were indicated that Korea wins a lawsuit against the matter of shipbuilding subsidy whereas losing the lawsuit against the matter of DRAM subsidy. It means that the case of shipbuilding subsidy do not violation WTO ASCM and the case of Hynix DARAM is against WTO ASCM. Additionally, as we see the dispute cases concerned Korean industry, it is necessary that government should operate subsidies which were provided for certain governmental policy as consisted with WTO ASCM.
