The main purpose of this study is to design the port maketing strategies for strengthening the competitive power of container terminal. So far many attempts have been to analyze the international competitiveness of the terminal. As a results, Six factors hypothesized by this study come from previous research analysis about customers preference for port selection. Those are Cost, Centrality, and Intermediacy, Free trade port, Inland transportation connections, Political and Economic institution, and Port facilities. This study analyze the most important factor about hub port, and transhipment port separately, though questionnaire analysis about users(shipper, shipping company, and freight forwarder) influenced on port selection. The results of this study were found as follows : Equations See Full-text

A research model was developed to examine the relationship between the anticipated benefits of electronic commerce and competitive strategies. A survey questionnaire was sent to 2000 electronic shopping malls in Korea, and 102 usable responses were obtained. The survey asked about the anticipated benefits from using electronic commerce. The survey also asked about three strategies that they have been following to achieve business competitiveness. The results provide useful guideline to develop appropriate strategies and plans for effectively deploying and managing the use of the electronic commerce. Customer responsiveness was the most important factors among six benefit factors, namely customer responsiveness, market responsiveness, economies of production, internal organizational efficiency, overall performance, and flexibility. Overall performance also predicted a focus strategy whereas flexibility predicted a cost leadership strategy.

In order to improve the international competitiveness of ferrule industry, the core technology of the second stage for ferrule grinding system is under developing. A high speed (10,000RPM) and high precision spindle system(Radial Runout 0.2 micrometer) bearing more cutting torque and force is designed considering the limitation of cost and size, the effect of heat, and various work-piece materials. A CAE software for machine elements and general machine system is used for preliminary evaluation and selection of design parameters. A dedicated program for the analysis of spindle system is used for final evaluation and selection of design parameter. The process how to evaluate and select using such tools are presented.

The market share of plastic fuel tube in automobile part is now growing rapidly. Especially fuel tube makers have had their efforts to develop tube module not only with dimensional accuracy, spring back and cost competitiveness. In this study, we used steam bending process for heat relaxation on PA12 plastic fuel tube's 128 types experimental bending conditions. we present the results of this process system in term of dimensional accuracy, and spring back.

The e-catalog system consists of e-catalog database. e-catalog manager. and a web server, and provides e-catalog web service by displaying e-catalog documents that contain web 3D images. product specifications and manuals. Various web contents such as the 3D images of products, which offer basic viewpoints/movement handles and function simulations, product specifications, product manuals and product features, can be integrated into e-catalog documents in XML format through image manipulation and database connection by using the e-catalog manager tool. By reducing time and cost for publication and management of an e-catalog web service, the competitiveness of companies is expected to be intensified in the perspective of e-business activities.

In order to increase competitiveness and to gain economic benefit, companies ask more and more how to recycle their products in a efficient way. So far, to answer this question, companies are not sufficiently supported by suitable methods specially in the area of disassembly process planning. For this reason, we develop in collaboration with an industrial partner a new method for generating an optimal disassembly sequence. In the presented paper this method will be described in detail by considering the exiting assembly information, disassembly method and disassembly depth. PLM (Profit-Loss Margin) curve that is used to determine disassembly depth consists of profit value, disassembly cost and disassembly effect. Using assessment parameters, generated alternative disassembly sequences are evaluated and optimal disassembly sequence is proposed. This method is applied to generate the optimal disassembly sequence of Door Trim as an example.

This study analyzed the amount of displacement of window wipers according to pressure by using finite element analysis (FEA) with KS standards for aluminum alloy window wipers manufactured by die-casting method. The product design was changed over four steps considering the die-casting process to achieve strength greater than that of the conventional steel window wiper. According to the FEA results, the strength of final aluminum alloy window wiper improved by 55% over that of a steel window wiper, and the weight of the former was less by approximately 45%. Therefore, there is the possibility of module downsizing for driving motor capacity. Further, the cost competitiveness improved, and the manufacturing process of aluminum alloy window wipers was simplified.

Multi Progress Planning System problem in a multi-stage manufacturing system have a complexity and peculiarity different from other kinds of production system. World leading company has invested much cost and effort into a Real-Time Planning System and intelligent manufacturing field to obtain their own competitiveness. Especially Real-Time Planning System for ship production process as a part of intelligence for a shipyard. Real-Time Planning System, simulation based system, or virtual manufacturing system is an approach to achieve a such goal. It is expected that the Real-Time Planning System will contribute to the improvement of the productivity in working process at a shipyard. Also, This Real-Time Planning System will optimize the entire shipbuilding process in a multi progress planning environment for the delivery.

PRAM(Phase change access memory) has desirable characteristics including high speed, low cost, low power, and simple process. PRAM is based on the reversible phase transition between resistive amorphous and conductive crystalline states of chalcogenide. However, PRAM needs high reset current for operation. PRAM have to reduce reset current for high density and competitiveness. Therefore, we have investigated the reset current of PRAM with top electrode contact hole size using 3-D finite element analysis tool in this paper.
