A dedicated CAM(Computer-Aided Manufacturing) system has been developed, which generated tool-path to machine Styrofoam stamping die-patterns in Chrysler Corporation. A previous process to build die-patterns was to "stick build" the pattern, in which stock is cut & glued together, and then the NC machining of part-surface shape completes building a Styrofoam die-pattern. The current process utilizes the developed CAM system, and almost removes the manual work, consequently reduces the overall lead time. The paper presents the overall system structures, tool-path generation, and some features of Styrofoam pattern machining.

Computer automation, developed into a major element of modern industry, has also brought to great change in textile design field. Traditional textile designers have been created patterns by free hand drawing with brush. The modern textile designers create and present, on the other hand, printed or woven designs much more utilizing extensively the computer cad as design tool, creating various designs and colors as well as reducing the creative process. Vine pattern the worldwide known is not a pattern simplified from a specific plant but it is rather a plant imaginative pattern that has been developed from a winter plant found in ancient Egypt. Vine patterns express gorgeous curve lines, which are simple but decorative by connecting flowers or leaves with stems. These vine patterns have also been widely used for their decorative arts in Korea since early times because they were believe to a favorable auspice pattern symbolizing a long-life and fertility. In this study, the possibility of developing various designs is explored and presented by utilizing the motif of vine pattern in CAD program.

Samples were 217 housewives residing in metropolitan area. Questionnaire included 17 Likert type items of bedclothes pur-chase motive measure 12 items of color preference 7 items of pattern (floral geo-metric abstract stripe plaid polka dot, and paisley pattern). The results of the study were as fol-lows. 1. 5 factors of bedclothes purchase mo-tives were derived by factor analysis ; F .1 'design': F 2. "brand' ; F.3. 'deficiency'; F. 4. 'fabric' F.5. 'economical reason' 2. Subjects perceived design and utility area to be important motives for bed-clothes purchase. 3. Cholor preference of bedclothes was in the order of white pale blue pale green and pale orange. Pattern preference was in the order of stripe plaid solid color floral and polka dot pattern. The combi-nation of patterned fabric and solid color fabric was liked better than the combina-tion of analogic color and the combination of contrasting color. 4. The women in their 20's liked navy blue red stripe plaid pattern and solied color better than 30's and 40's . 40's liked abstract and paisley pattern better then 20's and 30's 5. Low income group lied navy blue and solid color fabric more than the mid-dle and high income group and liked ab-stract pattern less than the middle and high income group. 6. Women in their 20's perceived design to be important motive more than 30's and 40's. 30's perceived brand to be im-portant motive than 20's and 40's 7. High income group perceived design to be important motive more than the middle and low income group. Low in-come group perceived brand and fabric to be less important motives than the middle and high income group, The present findings provide that age and income had a significant effect on bedclothes purchase motives and design preferences of houesewives. The results that white color and the combination of patterned fabric and solid color fabric were liked best indicated that women prefered clean image and chacteristics de-sign of bdeclothes.

Recent Internet of Things(IoT), and in addition to wearable PC, such as software development methodologies based on a variety of object-oriented design and design patterns of GoF(Gang of Four) with OOP(Object-Oriented Programming) intended for portable devices. However, incorrect application design specification is that the higher the importance of the optimization of the program on the device because it can cause problems such as decreased operating speed, increase the memory occupancy and battery usage. In this paper, we propose an optimized design pattern based on the method of application, such as Android (Android) OS Strategy Pattern, State Pattern, Observer pattern. Test results show that the proposed scheme selection patterns can be selected to optimize the design pattern in the device that specification.

A computer simulation method for textile designs was developed using a generic-purpose graphics program, LUMENA and its results were applied for costume design simulation. Its design performance was comparable with those using specialized design package programs which are in general very expensive. Three areas of textile design, print pattern design, weaving design, and knitting design, were covered. In the print pattern design simulation, a gird network library was constructed by using basic methods of repeat, and a pattern library by scanning existing print patterns. Through the modification and synthesis of library patterns, many new print patterns could be obtained. In the weaving design simulation, a thread library and a draw-down library were constructed. Using them, simulations of woven textile structures were carried out. In the knitting design simulation, a stitch library and a detail library were made from various types of knit stitch and detail drawings of knit costume, respectively. They were used to make structural knitting patterns and jacquard knitting designs. Using those simulated textile designs, costume design simulation was carried out.

A coverglass pattern was designed to improve the annual electrical energy production of a building-integrated photovoltaic (BIPV) module installed in the exterior walls of buildings. The transmittance pattern was calculated using ray tracing, and the results were derived by optimizing the simulation using Taguchi's method. We obtained the optimal pattern by analyzing the conventional patterns for improving the transmittance and derived design factors by quantifying the pattern. By calculating the influence of electrical energy on each design factor, we obtained the optimal coverglass pattern that produced the maximum annual electrical energy. The annual electrical energy production improved by approximately 11.79% compared to the non-patterned coverglass.
