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.

In This Paper, we introduce an efficient IFFT design technique named for transmitter of OFDM (Orthogonal Frequency Division Multiplexing) system. In OFDM system, a cyclic prefix is inserted in forepart of OFDM symbol to prevent ICI(Inter-channel Interference) and ISI (Inter-symbol Interference). Attaching cyclic prefix causes delay in storing and copying IFFT result. The proposed IFFT removes this delay because its output is cyclic shifted by the length of cyclic prefix. So we can make a complete OFDM symbol by just copying the forepart of IFFT output to the end. In many cases, the length of cyclic prefix is 1/2n of FFT size, and this IFFT does not require additional hardware complexity and it does not cause any performance degradation.

In this paper, we design the nonoverlapping multicarrier modulation (MCM) system for high rate paging system and evaluate the Performance by computer simulation. In conventional paging system, FSK was usually used, but we select QAM for high bandwidth efficiency. Transmitter structure adopts that of 4-16QAM of the iDEN$\^$TM/ and receiver consists of symbol timing recovery, carrier recovery and automatic gain control. In addition, pilot symbol aided modulation (PSAM) which can overcome the simulcast fading channel is considered and we also propose the optimum pilot symbol pattern. Finally, we show the performance of the overall 4-16QAM system by computer simulation.

This study inferred the symbolism of shaman's costume in China from shamanism and types of shaman's costume in Naje, Deokgang-hyun, Guiju-seong, China through field survey. Shamanism in China has complicated aspects due to negotiations with other culture for a long time while maintaining its own consistency based on ethnicity. Symbolism of shaman's costume in Naje, Guiju-seong, China is observed as follows. First, the shaman's costume in China appears differently from every Jangcha in relation to the position of god appearing in Jangcha when Tolosa takes the position of god as a symbol of sex and god. In Naje of China, the most important shaman's costume indicating the position of god has a unique mask for every deity. It communicates that Tolosa wearing a costume appropriate for the god of wine shall become the god in that Jangcha. Second, the shaman's costume in China has something to do with Yin-Yang and the five elements theory of Taoism as a symbol of shamanism visio of the universe and system of reason. Most of Tolosas hosting Naje are men but dress up as women by wearing Nagun looking like a skirt. Nagun is usually red, the color of Yang, which symbolizes that by wearing such costume that takes color of Yang, Tolosa expels an ominous thing by balancing yin and yang and taking god's strong power. Third, Tolosa takes an eight-breadth Nagun, as a symbol of people. An eight-breadth worn by Tolosa in Naje strengthens the spirit of union and fight of the Tujia nationality who live in Deokgang-hyun, Guiju-seong through folk legends. In this course, a symbolic meaning of the national spirit has been provided on an eight-breadth Nagun, a shaman's costume.

This paper presents the architecture and design of a high speed asymmetric data transmission baseband MODEM ASIC chip for CATV networks. The implemented MODEM chip supports the physical layer of the DOCSIS(Data Over Cable Service Interface Specification) standard in MCNS(Multimedia Cable Network System) The chip consists of a QPSK/16-QAM transmitter and a 64/256-QAM receiver which contain a symbol timing recovery circuit, a carrier recovery circuit, a blind equalizer using MMA and LMS algorithms. The chip can support data rates of 64Mbps at 256 QAM and 48Mbps at 64-QAM and can provide symbol rates up to 8MBaud. This symbol rate is faster than existing QAM receivers. We have performed logic synthesis using the $0.35\mu\textrm{m}$ standard cell library. The total number of gates is about 290,000 and the implemented chip is being fabricated and will be delivered soon.

Game graphics provide players with a sense of immersion, leading to active participation. This paper aims to analyze the mythological meaning for symbolic design of game skill visual effects that reproduce the narrative and the worldview of games borrowing myths. The research method classified the visual effect image into a symbol of the form of a universal archetype representation and a symbol of color expressing the narrative in the game, and analyzed it by applying Roland Barthes' semiological scheme. Through this study, it was possible to analyze the meaning of visual effects as a mythical meaning that can be universally sympathized and an implicit meaning that symbolizes the narrative of the game. The symbolic expression of the visual effect, which reproduces the narrative of the game reflecting the myth, can induce players to engage and participate, and the design direction was intended to provide the visual effect to have a unique symbolism that reflects the game's mythical worldview of the game.

"Aloha" is the Hawaiian word that extends the warmth friendliness, and pride of the Hawaiian people to their island's visitors. The aloha shirt truly symbolizes aloha sprit to islanders and visitors alike. The earliest foreign settlers in the Hawaiian Islands were the Chinese and Japanese. They brought with them their myriad talents and trades, among them the art of tailoring. In July of 1936, a shirtmaker named Ellery J.Chun coined the term "Aloha Shirt" an apt characterization for such an eloquent garment. He was the first to make the shirt on a commercial basis. The shirt sold for as little as a dollar in Chun's own King-Smith store. The genuine aloha shirt is now regaled as a work of art and avidly sought out by collectors. When tourism came to Hawaii in the late 1930s, these unusal shirts were among the first thing that visitors had to have. Local designers and tailors worked quickly to meet the demand and began to expand the range of decoration to include palm trees and romantic beaches, tropical jungles and volcanoes, exotic flowers and scenes from polynesian legend. Therefore the aloha shirt had been born. The functional use of creative colors and amazing artistic renderings in these shirts certainly capture the simplicity and sprit of Hawaii. Aloha shirt is dress that display mystery and charm of Hawaii and cultural symbol of condensed Hawaiian mind. Furthermore, the innocence with which Hawaiians formerly translated their life and heritage onto fabric ranks these shirts with the finest of American folk art. Aloha shirt is made from cotton, silk, rayon in present and past. Most important design element of Aloha shirt is print pattern. Main print pattern of Aloha shirt are all over pattern, horizontal pattern, border pattern, Japanese pattern, picture pattern and back panel pattern. In this study I investigate the design characteristics and development process of aloha shirt.

OFDM Transmission system can effectively reduce ISI(Inter Symbol Interference) caused by multipath fading, especially in the case of broad band data transmission. Nevertheless, the delayed waves existing in a symbol degrade the transmission Performance at the receiver. Therefore when OFDM transmission system applies to mobile radio communication system, we have to remove the influence without intricacy. This paper proposes and design a new scheme in order to estimate propagation characteristics using the characteristics of distinctive OFDM signal which is inserted pilot signal periodically in frequency axis before IFFT at the transmitter Moreover, we introduce a cancellation scheme of delayed signal on the basis of the proposed estimation technique. Using these schemes, it is possible to estimate and cancel the Interference of the delayed signal before FFT at the receiver.
