Post-modernism exists with different shapes in overall cultural phenomena. Among the creative methods of composing post-modernism, there are representation, parody, plural coding, trans avant-garde etc. Summing up the influence of creative method of post-modernism on modem fashion led to the following results. 1. The phenomenon appears that value and valuelessness are easily reversed, and things with historical and traditional meanings are being ignored. 2. The boundary between higher culture and public culture is being disorganized, and mixed imitation phenomenon ignoring the differences between male and female is emerging 3. The mental and historial aspects in fashion pattern are highly thought of and the trend to understand human body from the various angles emerges. 4. In the consumer-oriented society, it appears in the form of meanings to achieve the self-achievement in individual life, to express one's idea and desire in the esthetical point of views. 5. It shows that through arranging the striking things and the distorted things, it takes the compromised method of re-appreciating the existing ideas. The phenomena in the post-modernism occurring in fashion design forced the concept of the uniformed existing fashion to be changed, creating a various fashions. That can just be called the dehumanization trend in the era of post-modernism, which is the most important formative feature in modern fashion.

In outdoor visible light communication channels and LED road illumination communications for the intelligent transport systems (ITS), inter symbol interference (ISI) due to multipath propagation prevents high data rate transmission. Indoor wireless optical communication systems utilizing white LED lights and on the road illumination have been studying about it. Generally, plural lights are installed in room and considered to the traffic information system using existing LED traffic lights. Therefore, their optical path difference must be considered. In this paper, the influence of an optical path difference has been investigated and two approaches against this problem are introduced. One uses on-off keying, return-to-zero (OOK-RZ) coding and the other uses optical orthogonal frequency division multiplexing(OFDM).

Future electric lights will be composed of white LEDs (Light Emitting Diodes). Indoor wireless optical communication systems utilizing white LED lights have been studying about it. Generally, plural lights are installed in room. Therefore, their optical path difference must be considered. In this paper, the influence of an optical path difference has been investigated and two approaches against this problem are introduced. One uses OOK-RZ (On-Off Keying, Return-to-Zero) coding and the other uses optical OFDM (Orthogonal Frequency Division Multiplexing). From the results of computer simulations, we have found that these approaches are feasible for the wireless optical communication systems utilizing white LED lights.
