We believe distinguishable product development to be competitive against foreign products, and realize the need to expand domestic business worldwide. In order to be competitive, we should produce fashion items that meets global taste, and at the same time contain exclusive Korean culture and emotional beauty. This article examines and creates unique textile design with the touch of Korean art. Desigus have been proceeded under the following three themes: 'Strong Ego,' 'Gorgeous Days' and 'Song Eternal Seeking Love' using Primavision Computer-aided Design ("CAD"). We have put our interestes in Korean traditional paintings called Hangukhwa. Suitable design motives had been selected and modified from the four gracious plants (bamboos, peonies etc.), and paintings of birds and flowers. Primavision, a CAD software, had been used to manipulate those desigus, and to add instant changes in color, scale, and layout. We had modified Korean traditional motives to make modem image, and had arranged layouts which can be suitable for half-drop repeat and square repeat. The use of color is essential in pattern design. Thus, we explored coloring ways for each design to meet the trends, and the final mapping had been conducted in western style of dresses. We have tried to mix Korean image of textile designs with Western clothing style, expressing hybrid in the mapping process. With global movements, we need to develop products with Korean traditional exotic taste to attract foreign consumers. Therefore, we selected symbolic motives from Korean paintings to express deep spiritual significance. We developed textile design and processed mapping on selected western designer's dress, employing current trend colors and making crossover coordination. We realized Korean painting would be an excellent source for exclusive fabric design, and tried to create a modernized design which maintains Korean ethnical identities.

In a link motion punch press, numerous links are interconnected and each link executes a constrained motion at high speed. As a consequence, dynamic unbalance force and moment are transmitted to the main frame of the press, which results in unwanted vibration. This degrades productivity and precise stamping work of the press. This paper presents an effective method for reducing dynamic unbalance in a link motion punch press based upon kinematic and dynamic analyses. Firstly, the kinematic analysis is carried out in order to understand the fundamental characteristics of the link motion mechanism. Then design variable approach is presented in order to automate the model setup for the mechanism whenever design changes are necessary. To obtain the inertia properties of the links such as mass, mass moment of inertia, and the center of mass, 3-dimensional CAD software was utilized. Dynamic simulations were carried out for various combinations of design changes on some links having significant influences on kinematic and dynamic behavior of the mechanism.

Purpose: The purpose of this study was to evaluate the machining precision and the marginal and internal fit of single restorations fabricated with three types of lithium disilicate ceramic blocks and to evaluate the correlation. Materials and methods: Single restorations were designed using a CAD software program. The crown designed model file was extracted from the CAD software program. Three types of lithium disilicate blocks (Rosetta; HASS, IPS e.max CAD; Ivoclar vivadent, VITA Suprinity; VITA) were milled using a milling machine. For the fabrication of the crown scanned model file, the intaglio surface of the restoration was digitized using a contact scanner. Then, using the three-dimensional inspection software (Geomagic control X; 3D Systems), the process of the overlap of the crown designed model and the scanned model and 3-dimensional analysis was conducted. In addition, the marginal and internal fit of the crowns was evaluated by a silicone replication method. The difference among three types of single ceramic crown was analyzed using a Kruskal-Wallis H test, and Spearman correlation analysis was performed to analyze the correlation between machining precision and fitness (α=.05). Results: There was a significant difference in the machining precision and the marginal and internal fit according to the type of ceramic block (P<.001). In addition, the machining precision and the marginal and internal fit were positively correlated (P<.001). Conclusion: The marginal fit of crowns fabricated according to the types of ceramic blocks was within the clinically acceptable range (< 120 ㎛), so it can be regarded as appropriate machining precision applicable to all clinical as aspects in terms of the marginal fit.

One of the most important factors in the work environment of the industrial design is the design process which can systematically synthesize the informations of related fields. Because the computer technology is being radically developed, industrial should not only positively be able to cope with new technologies, but also should positively be able to take part in the development of the integrated system for the process by the new technologies. Recently in the industrial design field, designers are often using the computer~applied-3D modeling techniques in the development process of industrial design products, especially in the visualization level of the design development. In this paper, we studied the workstation modeling process to understand the computer~applied-3D modeling and presented the methods of transfer of the 3D-modeling data of a workstation(SGI) to the AutoCAD data of a personal computer which is generally being used as a drawing tool in mechanism parts. Through the development process of an electronic taxi meter as a practical case study, we check the possibility whether the 3D-modeling data transferred from an industrial design part to a mechanism part can directly be used as the mechanism data. For this, we transferred the 3D-modeling data of an electronic taxi meter created with a workstation(SGI) to the AutoCAD data of a personal computer and checked the usefulness of data transferred from an industrial design part to a mechanism part. Through these processes of data transfer, we aimed to find out the basic principles which can be rationally applied to a mechanism part or a production part.
