Mobile devices is getting to include more functions according to the demand of digital convergence. Applications based on 3D graphic calculation such as 3D games and navigation are one of the functions. 3D graphic calculation requires heavy calculation. Therefore, we need dedicated 3D graphic hardware unit with high performance. 3D graphic calculation needs a lot of complicated floating-point arithmetic operation. However, most of current mobile 3D graphics processors do not have efficient architecture for mobile devices because they are based on those for conventional computer systems. In this paper, we propose arithmetic units for special functions of lighting operation of 3D graphics. Transcendental arithmetic units are designed using approximation of logarithm function. Special function units for lighting operation such as reciprocal, square root, reciprocal of square root, and power can be obtained. The proposed arithmetic unit has lower error rate and smaller silicon area than conventional arithmetic architecture.

In this study, we present a 260k color TFT LCD driver chip set that consumes only 5 mW in the module, which has exceptionally low power consumption. To reduce power consumption, we used many power-lowering schemes in the logic and analog design. A driver IC for LCDs has a built-in graphic SRAM. Besides write and read operations, the graphic SRAM has a scan operation that is similar to the read operation of one row-line, which is displayed on one line in an LCD panel. Currently, the embedded graphic memory is implemented by an 8-transistor leaf cell and a 6-transistor leaf cell. We propose an efficient scan method for a 6-transistor embedded graphic memory that is greatly improved over previous methods. The proposed method is implemented in a 0.22 ${\mu}m$ process. We demonstrate the efficacy of the proposed method by measuring and comparing the current consumption of chips with and without our proposed scheme.

This paper deals with the difference between human sensibility collected from real product and that through graphic image(photographs and graphic images on CRT monitor) on the same automotive interior. The objective of this study is to verify the possibility that, If there are some restrictions in collecting human sensibility through real product directly, they can be overcome by using graphic image instead, making it easy to collect and analyze human sensibility so as to reflect consumers sensibility in the design of automotive interior, and also comparing the result between real product and graphic image on CRT monitor in order to confirm the potentiality of developing a remote human sensibility survey system through Internet. Therefore two experiments were conducted and the object for experiments was limited to automotive interior. The analysis results showed that there were significant differences between graphic image and real product in case of total interior and IPC(Instrument Panel Center) and no significant difference in case of display panel. Also, there were no significant difference when the subject group was female(housewife). To conclude, we can infer, in case of display panel, that it is possible to replace real product with graphic image to extract similar results on human sensibility and to collect human sensibility through Internet.

1930년대 나치 정권으로 인해 유럽에서 예술 활동에 제약이 많이 발생하자 유럽의 모더니즘을 이끌던 많은 예술가들이 미국으로 이주해 왔다. 이들이 미국 각지에서 디자인 활동을 시작하면서 유럽의 모더니즘을 미국에 알리고 미국 디자인에 많은 영향을 주었다. 이들의 영향을 받은 미국 출신 디자이너들의 활약은 1950년대부터 돋보이기 시작했다. 허브 루발린(Herb Lubalin: 1918-1981), 폴 랜드(Paul Land 1914-1996), 브래드버리 톰슨(Bradbury Thomson 1911-1995), 솔 바스(Saul Bass 1920-1996)등이 대표적인 작가들이다. 이들 중 허브 루발린은 6,70년대에 미국에서 가장 유명했던 그래픽 디자이너 중 하나다. 본 논문에서는 유럽의 모더니즘 디자인이 미국에 영향을 준 시대적 배경을 알아보고, 이러한 영향을 받아 미국 6,70년대의 그래픽 디자인을 주도한 허브 루발린의 작품에 대해 분석한다. 허브 루발린은 타이포그래피가 단순히 문자적 의미를 전달하는 것만이 아니라 '시각 이미지'로서 사용될 수 있다는 것을 증명해주었다. 그는 다양한 실험정신과 독창적인 창의력으로 새로운 타이포그래피의 표현을 가능하도록 해 주었으며, 이로 인해 인쇄 기술도 끌어올려주었다.

LED design works make user experience the conditions of time and space, and enable maximized spatial exploration and pursuit of ultimate sources. Light itself includes an ample dimension of time and, through the process of on and off, time-duration, similarity, and discontinuation is reorganized. LED design works make people experience the conditions of time and space, and enable maximized spatial exploration and pursuit of ultimate sources. LED design have been approached more from the viewpoint of material than from the viewpoint of aesthetics. LED based environmental design will be embedded deeply into our life with the technology of ubiquitous city. As the problem of the light intensity, tempo of change LED motion graphic and colors, substitutability is almost completely resolved now, LED is have more potentials than any other material as a tool of motion graphic. These result well make that using of LED is could be better useful from now on. In edition, users could be offered better beneficial lighting environment, and they will enjoy their better lives in the future.

The purpose of this design is to find out the design for an ophthalmic hospital focusing on the patient needs and changed healthcare environment. A cellularized hospital system appears variety design. This space needs well-balanced and ease of mind, because of ophthalmic needs a clear description attention. The concept of this design is to give human colour intellect and rich colour-sense. The waiting area wall is finished the graphic design sheet of leaves, which is covered with the fluting glass and indirect lighting. The colour is extracted in nature. The colour techniques of graphic design is gradation, the colour plan select from Y to G-GB. The material is selected within natural colour. The treatment area is functional space and the waiting area is sensitivity space. The hospital design must change with user as a leader.
