Recently Korean textile industry has been in the phase that requires its strategy change from the less-develped country style of the labor-intensive products to the developed country style of the technology-intensive products. It needs to make more efforts to develop the value-added products to meet the customer's various needs. In addition, development of technology, equipment, and design is required to implement its corporate strategy successfully. Although Korean textile companies have currently kept skillful labor and advanced equipments, they are losing their share in the international textile markets. This is mainly because corporate management has not been involved with efficient strategy. Strategy is an adoption of a company to environment by its corporate members, thus leading to the requirement of coordination of the main functions such as manufacturing and marketing. In fact, the coordination of the two departments toward reaching the corporate goal is not easy since the two are interested in different areas, respectively. Manufacturing people show their interests in production capacity, equipment layout, process technology, quality, purchasing, and labor while marketing people, target customer, product mix, advertisement, product specification, and customer service. For this reason, conflicts sometimes happen between the two departments. There are, however, many area that need a horizontal cooperation, for instance, in layout, process technology, product mix, and potential demand. Therefore, reciprocal coordination is necessary for achieving the firm's common objectives. This study was concerned with determining the factors that enhance the competitiveness of textile firms so that they could reach the common goal of the two departments with a horizontal collaboration.

This paper presents the application of topology optimization as a design tool for a steel railway bridge. The choice of a steel railway bridge is dictated by the particular situation that it is suitable for topology optimization design. On the one hand, the current manufacturing techniques for steel structures (additive manufacturing techniques not included) are highly appropriate for material optimization and weight reduction to improve the overall structural efficiency, improve production efficiency, and reduce costs. On the other hand, the design of a railway bridge, especially at higher speeds, is dominated by minimizing the deformations, this being the basic principle of compliance optimization. However, a classical strategy of topology optimization considers typically only one or a very limited number of load cases, while the design of a steel railway bridge is characterized by relatively concentrated convoy loads, which may be present or absent at any location of the structure. The paper demonstrates the applicability of considering multiple load configurations during topology optimization and proves that a different and better optimal layout is obtained than the one from the classical strategy.

Domestic power plants have consistently been developed over the years in industrially developed nations with high standards of living. Considering the power plant development strategy, design efficiency is of upmost importance. Therefore, an improper design directly affects the power plant's risk management plan and the potential risks of the piping system. Therefore, in this study, research is intended to be carried out to allow efficient power plant operation, through optimization of the design of the piping system. The purpose of the study is to confirm economic feasibility by changing the piping loop design, expanding the length of pipe loops, and to investigate the thermal stress influence on the piping system through simulations of systems similar in condition to those currently used in existing plants in Korea.

This paper presents a heuristic process-optimization procedure for minimizing warpage in injection-molded parts based on the dynamic robust design methodology. The injection molding process is known to have intrinsic variations of its process conditions due to various factors, including incomplete process control facilities. The aim of the robust design methodology advocated by Taguchi is to determine the optimum design variables in a system which is robust to variations in uncontrollable factors. The proposed procedure can determine the optimal robust conditions of injection molding processes at a minimum cost through a trade-off strategy between the degree of warpage and the packing time.
