동시공학적 측면에서의 R.P.(Rapid Prototyping) 기술 적용에 관한 연구
河光哲 서원대학교 예술문화연구소 2000 예술문화논총 Vol.9 No.-
In the 1990's, with competing products in every market segment-most produced with similar technologies, similar features and materials, and almost identical pricing; design may soon be the only element that differentiates one product from another. Industrial design is not merely a function. Design provides the essential link between engineering, manufacturing, and the market place, and in essence, is the primary ingredient to present and future success. These trends, coupled with rapid development in information technology, crate a far mor important role for industrial designers. It is no longer enough for industrial designers to be artists or stylists. The new generation of industrial designers will manage information, understand business, markets, materials and processes, as well as participate as equal partners with other organizational elements on cross-functional product development teams. Being competitive as an industrial designer will require adaptability and a progressive attitude toward product development. Companies will have to reduce product development "cycle time" to quickly get a product from the drawing board to market. It will also be necessary to generate a continuous stream of new products that can target market niches for increased market penetration, share, and company image. Designers and design firms will have to be adaptive to survive. They have to embrace the time and material saving capabilities of emerging computer technologies, which can provide the benefits of concurrent product development process. Using computers to model the complicated and sophisticated shapes of today's products correctly has become a trend. However, designers and model makers are still making the physical models by hand. Model-making is essential part of product development. We simply cannot overlook the importance of the accuracy of design models and engineering prototypes because they are the only means of real evaluation before the final products are made. By incorporating the R.P. technology in our product development cycle in right manner, we can eliminate the possbible reinterpretation in the successive departments by reading the 2D drawings. We have numerous computer-aided design systems available to us today. However, the key is implementation. By carefully evaluating different systems and the needs will only guarantee the perfect match for you and your companies and provide the leading edge.

ABSTRACTThe study was carried out to find the planting pattern of 44 multi-family housing sites in Seoul. Variables to identify the difference among sites were (a)number of households in site, (b)planting days, (c)total acreage, (b)planting acreage, (e)planting expenditure, (f)certified real estate price, (g)number of households in site/total acreage, (h)planting acreage/total acreage, (i)planting expenditure/total acreage. Data was analyzed by ANOVA, Duncan's multiple range test. Planting ratio of evergreen and deciduous trees were, on the average, 58, 49 and 41, 52 percent, respectively. And planting ratio of evergreen and deciduous shrubs were, on the average, 18.84 and 81.16 percent, respectively. The most frequently planted trees were Juniperus chinensis L., Pinus strobus L., Acer palmatum Thunb, Pinus parviflora Sieb. et Zucc., Acer triflorum Komarov, Zelkova serrata Makino, and Ginkgo biloba L. The most frequently planted shrubs were Ligustrum obtusifolium Sieb. et Zucc., Rhododendron schippenbachii Max, Buxus microphylla var koreana Nakai, Berberis koreana Palibin, Forsythia koreana Nakai, and Chaenomeles lagenaria Koidz. Results from ANOVA showed that planting pattern was siginifcantly different by the variables: (a)number of households in site, (b)total acreage, (c)planting acreage, and (d)planting expenditure.
