The purpose of this study is to reorganize any rusty image including natural modeling characteristic presented from the natural phenomenon to certain patterns in order to create the fashion design that are valued in the expansion of independently expressional area and modeling art. As a method for research, the author analyzed the concept and characteristic for rust with a base of theoretical background by the documental research and realistic consideration, analyzed its modeling characteristic through domestic and overseas pictures, and e-documents as data, inspected the modeling activities of various categories that various images were adapted related to rust, looked into the concept of Digital Textile Printing and its producing procedure as an expressional method, and analyzed the examples of modern dress and its ornament making use of Digital Textile Printing. The conclusions of this study are as below. First, the rust occurred due to the natural phenomenon is the bond with different material like metal, each unique modeling characteristic occurs and harmony of various patterns has abundant aesthetic value. Second, the author could endowed sensible characteristic and speciality with works and could produce creative fashion design that painting, abstractive pattern and harmony of unique sense of colors are significant by using the image of rust, Third, to emphasize natural feeling of rust, the author could develop creative design that simple silhouette and impressive pattern look significant by reorganizing and applying rust according to repetition, increment, rhythm, contract, emphasis and harmony. Fourth, Digital Textile Printing method is used to induce visual effect by the expression of feels of rust, and the author could express the natural patterns, delicate expression for the feels of a material and unique design of emotion.

역사적으로 볼 때, 지난 100여 년 간 자동차 개발의 경향은 기술적인 성능 위주로의 경쟁이 주도하여 왔다고 할 수 있다. 특히 첨단 전자 산업의 급속한 성장에 의한 자동차 기술력의 향상은 단기간에 걸쳐 괄목할만한 결과를 가져온 것이다. 초창기부터 고급차를 생산하는 일부 유명 제조 사에서 현재의 신흥 자동차 제조 사 까지 승용차를 위주로 한 개발기술 능력은 한계에 이를 만큼 매우 근소한 차이로 좁혀져 왔다. 따라서 이제는 자동차 선택의 기준에 디자인이 큰 몫을 하게되었다. 최근의 자동차 스타일의 경향은 보편적인 삶의 질의 향상에 따른 소비자의 다양한 욕구에 만족할 수 있는 개성 있는 디자인으로 변화되고 있다. 따라서, RV, SUV, MPV 등의 자동차가 등장하는가 하면, 각 차종별로 독특한 파생 모델이 나타나고 있다. 본 연구에서는 차세대 개념의 새로운 소형 SUV형 자동차 디자인에 대한 컨셉카 연구를 시도하였다. 리서치에서부터 최종 하드모델까지 자동차 디자인 프로세스에 의거 진행한 전과정은 대우자동차의 디자인 연구소에서 진행되었다. 특히 젊은 연령층이 쉽게 소유할 수 있도록 값싸고 개성 있는 새로운 카테고리의 자동차 개념을 스타일화 하였으며 고객의 반응도를 조사 분석하여 차후 경 SUV 자동차 개발에 참조될 수 있도록 하였다.

This paper presents the design results and characteristic analysis of SRM. For vehicle power supply for adaptable design of the SRM, variable design parameters, such as stator and rotor laminations, winding details, pole numbers, and pole arcs, phases numbers are required. So, in this paper the SRM design results and the comparison of characteristics for vehicle power supply as phases changed are described.

In the industrial field the necessity of the linear motion is increasing. We selected a moving magnet coreless type LDM, which have the advantages, such as long stoke, brushless, no cogging force. Actually, the design is accomplished using FEM analysis for the basic configuration of a magnetic circuit, and characteristic equations for coil design. In the course of design we have estimated airgap flux density and thrust.

In the present study, fuel system matching was analyzed, and a characteristic chart for common use for design-related parts is presented. Based on the characteristic chart thus presented, controlled fuel system matching was tested for a 35-liter fuel system, and actual mass product movement coils were applied to validate the test. The keynote of the present research is the use of the characteristic chart to devise a preferred fuel system matching method. Through the present study, it will be possible to design standard parts for efficient fuel system matching in the near future.

An approach to compute characteristic curves such as section curves, reflection characteristic lines, and asymptotic curves on a surface is introduced. Each problem is formulated as a surface-plane inter-section problem. A single-valued function that represents the characteristics of a problem constructs a property surface on parametric space. Using a contouring algorithm, the property surface is intersected with a horizontal plane. The solution of the intersection yields a series of points which are mapped into object space to become characteristic curves. The approach proposed in this paper eliminates the use of traditional searching methods or non-linear differential equation solvers. Since the contouring algorithm has been known to be very robust and rapid, most of the problems are solved efficiently in realtime for the purpose of visualization. This approach can be extended to any geometric problem, if used with an appropriate formulation.

We know that curriculum is, first of all, related to teaching materials, namely, contents. Therefore, when we think of mathematics curriculum, we must take account of characteristic of mathematics. Vygotsky has studied the development of scientific concepts and everyday concepts. According to Vygotsky, scientific concepts grow down through spontaneous concepts; spontaneous concepts grow upward through scientific concepts. And mathematics is a representative of subjects dealing with scientific or theoretical concept. Therefore, his study provides scientific basis for mathematics curriculum design. In this context, Davydov notes that everyday concepts are developed through empirical abstraction, while scientific concepts require a theoretical abstraction. And Davydov constructed the curriculum materials for the teaching of number concept. Davydov's curriculum is an example of reflecting Vygotsky' theoretical view and his view about the types of abstraction. In particular, it represents mathematical characteristic of a 'science' by introducing number concept through quantitative relationship and use of signs. In conclusion, stance mathematical concepts have scientific characteristic, mathematics curriculum reflects this characteristic.

In this paper, the effect of volute area distribution on the performance characteristic curve of a centrifugal pump were numerically studied using a commercial CFD code. To reduce the shutoff head, maintaining head and efficiency at a design flow rate, the flat head-capacity characteristic curves in which the head varies only slightly with capacity from shutoff to design capacity are frequency required. In order to control the shutoff head of a pump, several volute area distributions were proposed as a main parameter with the same impeller geometry. The calculation results show that the characteristic curve of a centrifugal pump can be controlled by modifying the area distribution with the same volute outlet area.
