대상을 상징하는 기호로서의 의미를 포함하고 있는 기하학적 패턴은 조형표현에 있어서 20세기 이후 예술가들의 작품을 통해 재구성되어 현대적인 이미지를 나타내는 중요한 모티브가 되고 있으며 패턴의 단순하고 간결한 형태는 외형뿐만 아니라 문양 장식을 통하여 새로운 아름다움을 창출하고 있다. 기하학적 패턴의 문양장식은 단순화되고, 이성적이며 현대적인 세련미와 잘 어울린다. 이렇듯 기하학적 패턴을 활용한 문양은 팔각형, 반원, 삼각형, 사각형 등의 기하학적 도형들을 이용하여 단순한 미로 현대인에게 만족감을 준다. 또한, 기하학적 패턴은 규칙적이고 단순명료하여 시각적으로 강렬한 효과를 유도하며 운동감과 속도감이 주는 역동성으로 3차원적 공간감으로 확장되기도 한다. 이로 인해 주목성이라는 특성이 나타나는데 테이블웨어에서도 이러한 기학학적 패턴을 이용한 디자인은 강한 주목성으로 시각적인 즐거움을 준다. 또한 이는 우연성의 요소에 근거해서 만들어지는 형태가 아니기 때문에 객관화될 수 있으며 반복적인 재현이 가능하다. 이러한 반복구성은 테이블웨어를 만드는 많은 디자이너에게 영향을 줄 수 있으며 테이블웨어 디자인을 더욱 더 고급화하여 도자 산업에 고부가가치를 창출할 수 있는 새로운 가능성을 제시할 것으로 생각된다.

The purpose of this study is to develop geometric patterns which can be reinterpreted in a modern sense and textile designs which can be commercialized in the mural painting of Goguryeo Dynasty's tomb. Of 42 tombs where genres and portraits could be observed, the costume style of Goguryeo dynasty could be mainly observed in the tombs built in the 4th and 5th centuries. Since geometric patterns found in the portrait could be represented in a modern sense, this study was intended to develop the patterns of a necktie which is one of cultural products by applying geometric patterns in the mural painting of Goguryeo Dynasty's tomb in the 5th century with many patterns distributed. The scope of patterns was limited to a square, a triangle, a circle, and a diagonal line which were the basic of geometric patterns found in the mural painting. The methods of study were literature review and empirical study. Adobe Photoshop CS3 was used to edit geometric patterns found in the mural painting of Goguryeo Dynasty's tomb in the 5th century. By extracting a square(${\square}$), a triangle(${\vartriangle}$), a circle(${\bigcirc}$), and a diagonal line(${\diagdown}$) from edited images, predicted images were proposed before products were made. Finally textile designs were made through the simulation of edited design patterns in the necktie and handkerchief. This study will contribute to the positive effects on the development of cultural product designs applying the characteristic of geometric patterns and the construction of Korean image.

The study intends to seek the creative ideas that can satisfy the needs of individual consumers by rediscovering the modern meaning and the artistic value of geometric ornaments engraved on the backside of Danyugyung, which is a traditional Korean pattern. In terms of the study method, the symbolic meaning and formative characteristics of Danyugyung were determined, and the form of its pattern and the geometric characteristics were analyzed. Based on this, Photoshop and illustrations were used to apply the shapes of Danyugyung and internal patterns to the textile designs, and the results are as follows. Firstly, it was found that Danyugyung was associated with the bronze mirror, which was used from the Bronze Age to the Early Iron Age, and was the product of artistic activities and an object and acted as a shamanistic and authoritative symbol of the ruling parties, which were responsible for the acts related to the spiritual world. Secondly, it was discovered that forms of Danyugyung were classified into Jomungyung and Semungyung in accordance with Forms of Danyugyung (造飾), and the formative features of the geometric ornaments that were engraved in great detail on the backside could be found in the images which change according to the form of the inner patterns. Thirdly, with regard to the development of the textile designs utilizing the shape and inner patterns of Danyugyung based on the formative features, it was could discover that the simple shape of Danyugyung presented a value which can be applied as a unique design factor delivering a visual rhythm by attempting to create various harmonies overlapping lines engraved on the inner patterns and the shapes of Danyugyung. Based on the above-mentioned outcomes, the possibility was confirmed that Danyugyung can be used as a novel motif and as a standard unit of patterns for textile design. With future studies, I would like to utilize the unique and diverse images as pattern motif for textile design.

PURPOSES : It is desirable for buses to be parallel to the face of the bus shelter at a bus stop. In this way, passengers can safely use the buses without moving into the vehicle area. The study was a review of the current bus bay geometric guidelines, to determine whether they lead buses to stop parallel to the face of the bus shelter by analyzing vehicle trajectory. METHODS : A commercial software program for vehicle trajectory analysis was used under our assumptions about bus dimensions and geometric values. The final position of the bus was analyzed for multiple trajectory simulations, reflecting various geometric alternatives. RESULTS : Within the scope of the study, we concluded that the current design guidelines need to be revised by the design values suggested by the study. CONCLUSIONS : The results of the study suggested alternative design values for bus bay geometry, based on the assumption that buses should be parallel to the face of the bus shelter in order to prevent passengers from moving into the vehicle area.

Danchung(丹靑) is the traditional Korean patterns that are decorated with various colorful patterned paintings upon each sections of wooden architecture. Although Danchung consists of variety patterns with the meaningful signs and symbols, as an accomplishment of Korean traditional images, there is a few fashion merchandise by Danchung patterns. Therefore, the purpose of this study is about to design Jacquard fabrics, and to develop bags of Jacquard fabric by Danchung patterns, as a differentiated cultural Fashion Merchandise. The theoretical background was researched for the geometric image of Danchung patterns on the basis of the basic elements, compositions and symbolic meanings of Danchung. The geometric image of Danchung patterns, which had the shape of circle, triangle, square and hexagon, was designed to the surface design by Jacquard CAD system(i.e., EAT Designscope by Germany) and woven into Jacquard fabrics by Stabuli electronic Jacquard system. Danchung patterns for fabric design in this study was mainly focused on 'ChipJaGum', 'SamJiChangGum', 'ShouSulGum', Moro patterns of lotus flower(蓮花), Rok-Wha(綠花) and so on. To development bags of jacquard fabric, those woven jacquard fabrics were manufactured to bags by applying the selected of twelve bag-designs among the current bag styles. These manufactured bags of jacquard fabrics in geometric Danchung patterns were appeared a contemporary yet ethnic feeling so that they can be used for the unique korean cultural products to further commercialization.

Unlike other press forming processes, ISF (Incremental sheet forming) doesn't require a punch and die set. However, during the ISF processes unwanted bending deformation occurred around the target geometry. This paper is aimed to analyze the effect of the die structure, which is supported by bolts, on the geometric accuracy of the ISF processes. In this research, the ISF processes with Al5052 sheet of 0.5 mm, the tool diameter of 6 mm and the stepdown of 0.4 mm was employed. L-shaped, step-shaped, relief-shaped geometry were employed in experiments. Sectional view and the plastic strain were compared. From this research we find out that the bolt supported ISF processes increases the geometric accuracy of products very effectively.

This paper analyses the geometric aspect of Soma Delaunay's works on the basis of design elements and principles. Geometric pattern is one of the distinct features of early 20th century avant-garde works. The significance of its pattern and colour comes from the fact that it has not only influenced the contemporary fine art but also offered the basic principle of modern costume design. In 1925 she was designing clothes which could be worn today without appearing old-fashioned. She foresaw the future trends in fashion and interior decoration, One might claim she belongs to the avant-garde even today and no less astonishing a phenomenon than she was in 1925. Soma Delaunay's art was one of the first expressions of abstract painting and her "simultaneous contrasts"are among the earliest example of the aesthete. In Delaunay's geometric abstraction it is found that the technique of"simultaneous contrasts" is exploited almost without exception. colour as well as collage was the favourite technique Delnaunay used in creating a distinct simultaneity, Many "inobjective" paintings as she herself called unite the rigour of simple geometric forms with an inner life and poetry which emanate from the richness of the colour, the musicality of the rhythm, the vibrant breadth of the execution.rant breadth of the execution.

In this paper, an integration framework of Geometric Constraint Solving Engine and AutoCAD is presented, and a dynamic geometric constraint system is introduced. According to inherent orientation features of geometric entities and various Object Snap results of AutoCAD, the' proposed system can automatically construct an under-constrained geometric constraint model during interactive drawing. And then the directed constraint graph in a geometric constraint model is realtime modified in order to produce an optimal constraint solving sequence. Due to the open object-oriented characteristics of AutoCAD, a set of user-defined entities including basic geometric elements and graphics constraint relations are defined through derivation. And the custom-made Object Reactor and Command Reactor are also constructed. Several powerful characteristics are achieved based on these user-defined entities and reactors, including synchronously processing geometric constraint information while saving and opening DWG files, visual constraint relations, and full adaptability to Undo/Redo operations. These characteristics of the proposed system can help the designers more easily manage geometric entities and constraint relations between them.
