This study empirically analyzed the mediating effect of technology absorption capacity in the relationship between technological innovation of ship parts manufacturing companies on business performance. Through this, it will be possible to provide implications for improvement plans for management strategy establishment related to technology development in the future. In order to achieve the purpose of this study, R&D, marketing, production·A total of 362 people working in manufacturing and finance/accounting departments were selected as subjects for this study. As a result of this study, it was found that technological innovation and technology absorption capacity of ship parts manufacturing companies have a positive (+) effect on business performance. The conclusion based on these research results is that the potential absorption capacity and realized absorption capacity constituting technology absorption capacity are judged to be the main key factors between technological innovation and management performance, such as continuous technological capacity accumulation. From a practical point of view, the ship parts manufacturing industry needs to focus on its ability to absorb smart parts process technology.

After the financial crisis in 2008, Korean ship-parts manufacturing companies faced the survival of companies due to the difficulty in securing the volume of orders by sharp dropping in orders from big-three Korean shipbuilders. In ship-parts industry, product diversification and overseas market entry are important targets. Based on the expert Delphi survey and SWOT analysis, this study analyzes the key factors of overseas advancement by the growth stage of ship-parts companies and suggests a systematic and efficient overseas marketing strategy. Also, we propose a systematic and efficient advancement into overseas market by suggesting the traditional offline marketing strategy of exporting materials, marketing and marketing, and suggesting the need to build an integrated online and offline platform.

Outfitting systems in marine vessels have many kinds of standard parts. Ship CAD system should support the designers with an efficient tool for the modeling of outfitting parts such as pipes and valves. We develop a practical procedure for a part master model that combines ship CAD systems with the industrial standard. Part master or catalogue database of standard equipments is included in the database of ship CAD. The part master makes the associations of three dimensional modeling with the industrial standard. Moreover, it reflects the automatic modeling to maintain attributes that are disclosed in the entity of each part master in order to reduce the modeling time. Entity and attributes of pipe and valves are chosen from JIS(Japanese Industrial Standards) in order to explain the proposed procedure. Suggested procedure explains that three dimensional model of equipment is generated by parsing the pre-defined attributes after the entities of part masters is stored in database.

The telegraph controller is a device used to control the speed of a ship, and it is a device that has a very direct effect on the safety of the crew. Accordingly, ship owners demand very high reliability of the telegraph controller, and the classification trend is to introduce HILS (hardware in loop system) test as a method to verify reliability. Therefore, in this paper, an electric propulsion ship was modeled to perform the HILS test of the Telegraph controller. For modeling, the specifications of the electric propulsion tug boat were defined, and the battery parts, propulsion motor parts, and ship model parts were modeled. In addition, various operation scenarios were defined and the Telegraph controller was modeled accordingly. Finally, the results of the integrated model were confirmed through simulation.

Arc welding is sometimes used to repair damaged cast iron parts in diesel engine for driving a ship. In this case cola arc welding. is good for. saving the time and results in good repairing. But if some difference in hardness on welding zones made with AWS E Ni-CI and NiFe-CI. happen, repaired parts would be cracked in a short. In order to overcome this default, the study is performed on varying preheating temperature of welding parts, selecting welding rod and welding work way. The result will be used on ship's repair working shop.

Arc welding is sometimes used to repair damaged cast iron parts in diesel engine for driving n ship. In this case cold arc welding is good for saving the time and results in good repairing. But if some difference in hardness on welding zones made with AWS E Ni-CI and NiFe-CI happen, repaired parts would be cracked in a short. In order to overcome this default, the study is performed on varying preheating temperature of welding parts, selecting welding rod and welding work way.

This paper analyzes the efficiency of Korean Ship Component Part Manufacturer firms using DEA model. We evaluated the CCR, BCC efficiency and RTS of 30 Korea Ship Component Part Manufacturer firms. We also suggested the Korean Ship Component Part Manufacturer firms that can be benchmarked based on analyzed information. The result showed five enterprises whose values of CCR efficiency are 1, and eleven enterprises whose values of BCC efficiency are 1. RTS indicated IRS of 1 firms, DRS of 24 firms and CRS of 5 firms.

This study is some parts, the contents on "Course of Power Machinery and of Automated-Ship Operation", of the results of the sixth curriculum, revision study for the fisheries high schools and merchant marine high schools. In this study, it was suggested that the existing name "the Course of Marine Engine" is revised to "the Course of Power Machinery" and "the Course of Automated-Ship Operation" is newly established. The purpose of the revision of the name to "the Course of Power Machinery" is to give the course a more flexible curriculum which enables the course to bring up not only sea duty marine engineers but also shore duty power engineers. Also, the purpose of the new establishment of "the Course of Automated-Ship Operation" is to bring up automated-ship operators. The necessities for automated-ship operator is derived from the process of ship automation to reduce the number of crew to cut down the expenses. The revised parts of the organization of the professional subjects exclusively related to "the Course of Power Machinery" and "the Course of Automated-Ship Operation" are summarised as follows; (l) The Automated-Ship are newly added. (2) The Sea Training, the Fisheries Law are Disused. (3) The Introduction to Ship, the Introduction to Marine Engine and the Introduction to Marine Communication are merged into the Introduction to Ship. (4) The name of the Marine Engine, the Shipping Business are revised to the Heat Engine, the Introduction to Shipping respectively. (5) M compulsory professional subjects, the Introduction to Fisheries is suggested for the fisheries high schools and the Introduction to Shipping is suggested for the merchant marine high schools.

Shipbuilding process is composed of hull construction, in which the structural body of a ship is formed, and outfitting, in which all the non-structural parts such as pipes, derricks, engines, machinery, electrical cable, etc. are manufactured, added and assembled. Hull construction can be classified into parts fabrication, block assembly and hull erection. Among them, the parts fabrication is the first manufacturing stage that produces components or zones needed for block assembly and hull construction. More specifically, the parts fabrication is performed through machining processes including marking, cutting, pressing, and/or forming. When material is entering into the parts fabrication stage, it is important for achieving the total efficiency of production to select one of production division, so-called 'bay,' as well as machine tools on which the part is fabricated. In this paper, given production quantities of parts in the fabrication stage, the problem is to optimally select machine tools and production division, such that the total flow-time is minimized as well as the workload among machines is balanced. Specifically, three mathematical models for flow-time minimization, load balance, and simultaneously considering both objectives, and a numerical example are analyzed and presented.
