For every country, the flag is a major symbol that represents the country. Establishing image though the use of the country's symbol is more important for achieving national competitiveness in this global age. In Korea, Taekuki has not been actively applied to fashion products, however Korean people began to realize the Taekuki as a motif of fashion with 2002 World Cup. Thus, research on fashion product development applying Taekuki is needed. This research developed designs for fashion product development applying Taekuki. In addition, through suggesting various applied motives, this research explored the product possibility of global fashion design that represents Korean identity and fashion. For research method, after research on fashion design process, design development was progressed according to the 4-phases that comprehends processes previous researchers presented. First, in the problem recognition phase, background on the introduction of Taekuki to products and Taekuki fashion during 2002 World Cup was analyzed. Then, the need and possibility of fashion product development applying Taekuki's formative characteristics were found. Second, in research and analysis phase, meaning and history of Taekuki as well as flag fashion product developments in the U.S. and England examples were reviewed. Also, individual interviews with experts and consumers were conducted to collect qualitative data regarding product and design direction. Third, in idealization for problem solving phase, 62 designs including 43 apparels and 19 accessories were emerged. Finally, in evaluation phase, 40 university students majoring design evaluated designs' creativity, function, uniqueness, symbol, aesthetics, and harmony. Through this research, it is expected that fashion products applying Taekuki will be formly established as a fashion item. Furthermore, it is also expected that product development in other categories, brand planning, and product development using other national symbols such as name, anthem, and flower will be followed.

In this paper, we analyze performance of PSPM(Phase Shift Position Modulation) modulation scheme in multi-path channel. A PSPM modulation method transmits the information data by both PSK symbol data and symbol position data, so that we can significantly improve the power efficiency. The bandwidth efficiency of PSPM is quarter than PSK but improve BER performance, because increasing symbol hamming distance. In this results, a PSPM scheme is bandwidth efficiency better than FSK and power efficiency better than PSK. This characteristic can be useful in WBAN and wireless sensor networks also PSPM modulation method can be expected high throughput than existing FSK. In this paper, we compare PSPM, PSSK and PSK regard to BER performance and throughput in multi-path channel.

The dragon is a special imaginary figure created by the people of East Asia. Its archetypes appeared primarily as totemic symbols of different tribes and groups in the region. The formation of early dynasties probably generated the molding of the dragon symbol. Dragon symbols carried deep imprints of nature. They concealed alternative messages of how ancient people at different locations dealt with or interacted with nature. Under pressure to standardize in the medieval and late imperial periods, the popular dragon had to transform physically and ideologically. It became imposed, unified, and framed, conveying ideas of caste classification and power, and losing itsecological implications. The dragon transitioned from a semi-ecological domain into a total social caste system. However, many people considered the "standardized" dragon as the symbol of the oppressor. Because of continuous orthopraxy and calls for imperial reverence, especially under orthopractic agenda and the surveillance of local elites, the popularized dragon was imbued within local artworks or hidden under the sanctity of Buddhas or popular gods in order to survive. Through disguise, the popular dragon partially maintained its ecological narratives. When the imperial dynasties ended in East Asia (1910 in Korea, 1911 in China, 1945 in Vietnam), the dragon was dramatically decentralized. However, trends of re-standardization and re-centralization have emerged recently in China, as the country rises in the global arena. In this newly-emerging "re-orthopraxy", the dragon has been superimposed with a more externally political discourse ("soft power" in international relations) rather than the old-style standardization for internal centralization in the late imperial period. In the contemporary world, science and technology have advanced humanity's ability to improve the world; however, it seems that people have abused science and technology to control nature, consequently damaging the environment (pollution, global warming, etc.). The dragon symbol needs to be re-defined, "re-molded", re-evaluated and reinterpreted accordingly, especially under the newly-emerging lens-the New Confucian "anthropocosmic" view.

This paper investigates the multifarious nature of the long-term evolution (LTE) scheme and that of the modified LTE scheme for symbol timing synchronization (STS). This investigation allows us to propose a new replica correlation-based STS scheme to overcome the inherent weaknesses of the other two schemes. The proposed STS signal combines a gold sequence and a half sine wave in the time domain, whereas conventional STS signals specify either binary sequences or complex sequences in the time domain or in the frequency domain. In the proposed scheme, a sufficient correlation property is realized by the gold sequence, and robustness against the frequency offset (FO) is achieved through the sine wave. Compared to the existing LTE-related schemes, the proposed scheme can better achieve immunity to FO and reduction in detector complexity, as well as a low peak-to-average power ratio and a low detection error rate. Performance evaluations through analysis and simulation are provided in the paper to demonstrate these attributes.

In this paper, the selective normalized constant modulus algorithm(SNCMA) is applied to a fractionally spaced equalizer. The fractionally spaced equalizer is insensitive to the sampling timing because it processes received signals with the sampling rate larger than the symbol rate. The SNCMA improves the convergence rate by using the large step size for the most outer covering symbol belonging to the trust-level. This blind equalizer exhibits a fast start-up convergence rate as well as a reduced steady-state residual error compared to the fractionally spaced blind equalizer and the T-spaced blind equalizer using conventional blind algorithms.

People have their own cultural backgrounds and experiences in terms of visual perceptional thinking so that they could misunderstand the cultural symbols, trademarks, Brand Identities, and trade characters, especially, animal trademarks. Sometimes Easterners and Westerners seem to not comprehend the different meanings of the cultural symbols. The signs of twelve Chinese zodiac animals are the typical symbol of the Asian mythology. What I wanted to focus on emphasizing the different views and perspective of an animal trademark is according to the Chinese Zodiac between Eastern and Western cultures. Generally, multiple symbolisms are difficult to comprehend, because they are created by individual ideas and incorporate several mythologies and histories. How do Westerners interpret the implied meaning of Eastern animals in general? How are they going to understand the Eastern animal logos or marks accurately? How can we solve the problem to make people understand their different meanings? There were some confusing pictorial images in the area of the design field when a designer creates an animal mark for globalization and localization. Creating of hybrid symbol is the best way to break the communication barriers with people all around the world.

This paper presents the application of a turbo coding technique combined with a bandwidth efficient method known as trellis-coded modulation. A transformation applied to the incoming I-channel and Q-channel symbols allows the use of an off-the-shelf binary/quadrature phase shift keying (B/QPSK) turbo decoder without any modifications. A conventional turbo decoder then operates on transformed symbols to estimate the coded bits. The uncoded bits are decoded based on the estimated coded bits and locations of the received symbols.

Conventional channel estimation methods for orthogonal frequency division multiplexing (OFDM) system don't show the good characteristics in terms of fast fading channels. To solve this drawback in conventional methods, we propose the channel estimation method fur OFDM, assisted pilot for improvement and convergence in mobile system (APIM), which has a good performance and computational complexity in consideration of other methods. APIM uses the more developed concept of conventional methods and a block frame structure within a whole channel. This concept prevents overall performance from diverging or showing a poor one. The simulation results demonstrate the APIM outperforms pilot symbol assisted modulation (PSAM) and extended symbol aided estimation (ESAE) in terms of mean square error (MSE) and bit error rate (BER) performance under all Rayleigh fading environment. Considering the simulation performance and computational complexity, we can see APIM shows better characteristics than conventional methods for OFDM and has not any error floor even in a fast Rayleigh fading environment.

In this paper, novel approximated closed-form expressions of the SER(Symbol Error Rate) and BER(Bit Error Rate) are presented for the multi-input multi-output space-time block coding(MIMO-STBC) system employing two transmit and N receive antenna(s) in Rayleigh fading channels. Assuming a zero-forcing equalizer and a single-symbol maximum-likelihood (ML) decoder, the formulas are derived for the SER and BER, and then their approximated counterparts are also derived. In the derivation of the approximated expressions, acurve-fitting model is adopted that can eliminate the integral operators in the exact expressions.

This study explored the background of contemporary furniture design called New Design furniture, which newly expresses the aesthetics of communication in the postmodern era. Qualitative conceptual analysis as the principle methodology was used to explore the background of the decorative and meaningful contemporary furniture in postmodernism. Thereby, the postmodern concepts of Charles Jencks, Robert Venturi, and Michael Graves were analyzed in terms of their postmodern architecture and furniture. As initiatives of postmodern architecture and furniture, Jencks, Venturi, and Graves explored the pluralism and eclecticism, the decoration, the semantics, and the materials reestablished from the traditions of craft. As a result, their furniture was expressed by various wood and color; the furniture was beautiful, decorative, pluralistic, and eclectic for communicating symbol, metaphor, narrative, and/or humor with people; the furniture has influenced the communicative elements on the contemporary furniture design called New Design furniture design, which shows the blurring of fine arts and craft distinctions.
