Quadrature spatial modulation (QSM) utilizes the in-phase and quadrature spatial dimensions to transmit the real and imaginary parts of a single signal symbol, respectively. The improved QSM (IQSM) transmits two signal symbols per channel use through a combination of two antennas for each of the real and imaginary parts. The main contributions of this study can be summarized as follows. First, we derive an upper bound for the error performance of the IQSM. We then design constellation sets that minimize the error performance of the IQSM for several system configurations. Second, we propose a double QSM (DQSM) that transmits the real and imaginary parts of two signal symbols through any available transmit antennas. Finally, we propose a parallel IQSM (PIQSM) that splits the antenna set into equal subsets and performs IQSM within each subset using the same two signal symbols. Simulation results demonstrate that the proposed constellations significantly outperform conventional constellations. Additionally, DQSM and PIQSM provide a performance similar to that of IQSM while requiring a smaller number of transmit antennas and outperform IQSM with the same number of transmit antennas.

This study selected brand logos of six South Korean and Chinese banks including KB, IBK, SH, ICBC, ABC, and SISB, conducted Eye Tracking experiment among 36 South Korean and Chinese university students(Nine male and female students, respectively), and analyzed the difference of visual attention of consumers on bank brand logo, symbol, Korean/Chinese character logo types as well as the difference of visual attention of these consumers on English logo types. Results were represented by using statistics and visualization including GAZEPLOT, HEATMAP, and visual expression. Results showed that most generally gazed logo types more often and longer than symbols when they watched bank brand logos. A slight difference was observed between both groups in terms of gazing English logo types. This study has a implication that it proposed the possibility of drawing quantitative and reliable outcomes by utilizing eye tracking device and approaching in an objective standpoint beyond a methodological aspect on bank brand logo primarily leaning over the analysis of case research or design development. Moreover, findings are expected to serve as basic data for proposing the direction of special bank brand logo design and marketing strategies.

The Trellis Coded Modulation(TCM) allows the considerable achievements of coding gains compare with conventional multi-level modulation without compromising bandwidth efficiency. In this paper, we are presented a design of the parallel Viterbi decoder for 16-QAM TCM decoder with large constraint length (K=9), which can be applicable for the Digital Audio Broadcasting(DAB) receiver. As a mid-term result, a parallel Branch Metric Calculator (BMC)can compute 16 BMs within 3 clocks and a parallel 16 Add-Compare-Selects (ACS) unit can compute in a single clock. And also, two 256 Path Metric Memories (PMM) 32 Trace Back(TB) memories are specially designed with shuffle exchange switches for 16 parallel accesses. As a VHDL simulation, we can find the correctness of proposed model, which can be operated 16 S per symbol. Now, we are performing the hardware reduction for realtime operation and FPGA implementation.

The purpose of this thesis is to investigate about the various metamorphosis methodology, which is one of the specific skill being used widely in contemporary metal-craft. Even though this methodology is being investigated actively in the other genre, it is not easy to find the example and various experimentation for further expression than in metal craft. The metamorphosis had been dealed little by little before the metal-craft is being modernized. Recentely, the experimentation is more deeply and widely held; because the deconstruction methodology, which is the skill to express the differance in the meaning: material's archetype and dealing with the symbol and metaphorical meanings concealed, is being developed. The special skills of the metamorphosis are Mokumegane, reticulation, Fusing, and electro form Mixed Media metamorphosis; these investigation is being further developed with metal alloy methodology.

Patterns have their own shapes and characteristics as a symbol in accordance with in what environment they are like a language. Especially our ancestor had wished present values as like riches and honors, longevity and health, love and happiness through all kinds of patterns of animals, plants, the sun, the moon, cloud, water and mountain, and expressed an aesthetic consciousness. Pattern design is important in fashion but it is insufficient in terms of the development of modern patterns based on Korean traditional patterns. Therefore, We need to create new senses and thoughts through the understanding and re-analysis about Korean traditional costume and a study on optical patterns could give an extreme effect without any changes of silhouette. Especially, Emilio Pucci and Missoni have been developing a variety of Pattern designs even though there are different tendencies each other. Consequently it could be a good chance to show Korean images and originality that develope the various textile patterns with applying to Korean traditional patterns based on an analysis of their works.

This article is to study the ancient Korean make-up based on ancient men's and women's facial decoration. The adornment is mainly about make-up, but I didn't employ make-up in this article on the ground that it isn't an appropriate concept in men's case. The study on the ancient Korean make-up has been conducted on the basis of Goguryeo mural paintings excavated in the tombs. Contrary to the Baekje and the Silla Kingdoms, Goguryeo women's make-up carne to fashion like China. The Goguryeo mural paintings depicted women's make-up which painted their faces white and lined on the eyebrows to make them raise toward their foreheads after removing their own eyebrows. They outlined their mouths smaller than their own and, in some occasions, applied make-up differently on the upper lip and the lower lip. As the time passed by, women applied the blusher, which attests to the fact that make-up of those days was considerably developed. Unlike women, men didn't put on cosmetics but they grew beard as a symbol of adults. The beard had a diversity in shape such as goat-shaped and fan-shaped beards. It can be understood that women's make-up was applied as a manifestation of adults like men's growing beards.

Certosa, a representative Monastic Architecture of Renaissance era, has been well preserved. And it has worked as a symbol of the space form & style revealed by monad, sell, arcade and court, which are characteristic of a monastery. A court is divided into large court and small one, and it connects each units and each sells through the annex with clarifying each space identities. And arcade and pillar is not only to derive a unitary space from entire space, but also to try openness and extension applying a different height in spite of physical closure of style. Especially planned by monad and cell, the routine space of monks, a structure of rational space is a yardstick of moderation and frugality, showing affluent space which occupy essential areas without extra space. And the space appears self-sufficiency, honest poverty, and affluence with order and eternity based on elementary principles of the Cartusio order in composition and plan of the space. Keeping strong linking with entire sells in the monastery, Each sell symbolizes entire sells, and the inverse is the same. And it is the universe advocating eternity and it is also a small city which provides the monks with accurate modules and scales in the very recluse space.

This research was conducted to activate the horne shopping by providing the basic data about demographic characteristics, purchase practices and satisfaction degree of women consumers. The subjects were 328 women consumers residing in Cheongju who had purchased apparel products through home shopping. Collected data were analyzed by frequency analysis, t-test, analysis of variance, and cross-tabulation analysis using SPSS. The results were as follows: 1) When purchasing formal wears, casual wear and furnishing textile products through home shopping, respondents considered the design and fiber content seriously, and when purchasing underwear, the fiber content and size. 2) When purchasing apparel products, most of respondents confirmed apparel labels, and married women confirmed more than single women did. Among apparel labels, fiber content, care symbol, and size were the items that respondents considered most. 3) The single women managed internet and knew the value of internet in searching information or purchasing apparel products better than married ones. 4) When purchasing apparel products via home shopping, respondents used TV, catalog, and internet in order. 5) Degree of satisfaction for clothing purchased via home shopping was in ordinary level, high for furnishing textile products and low for formal wears.

Today, The representation of the modern space is experimented with shape and surface of the de-structural point of view to make architecture and space, in terms of not being able to make defined by single regulation. However, it can correspond to the rapidly changing modern, but it is easy to fade of architecture fundamental meaning. Along with the need for the rise of the construction of fundamental space, should be built a 'tectonic' spatial, which is said to be building of logos. Tectonic, as norms for expressing the fundamental meaning of architecture, as to expression of construction, be unfolded with dualism such as science and art, technology and express, structure and formation, and it was introduced into the architecture through the construction expression of space that was a tectonic discussion of 19c german architects. On the other hand Constructivism which is avant-garde formative movement with Russia revolution, constructed 'sculpture' with the formative principles as tectonic. Tectonic's Formative characteristics can draw a conclusion with of tectonic characteristics of constructivism sculpture, space of logos will be realized through its study. Other hand, The pavilion, as symbol space, can be analyzed by tectonic properties, Pavilion, meaning the space is expressed in a variety of tectonic expression. As tectonic construction, fundamental ideology and symbolization of space is revealed metaphorically and visually.

The purpose of this study is to find the relationship between hightech architecture and digital one through the discussion on Karl B tticher's view on tectonic in 19th century. The discussion of tectonics which has not been brought up until recently. Since there are no studies regarding contemporary architecture relating to Karl B tticher's view on tectonic, so it is fairly significant to study Karl B tticher's conception, discussion and relationship of contemporary architecture. To study the essence and meaning of Karl B tticher's view on tectonic in 19th century, we will analyze each examples of hightech architecture and digital architecture through Karl B tticher's dual form. B tticher insist that dualistic relationship is united and produced simultaneously. Because they have so closed relationship each other, it's impossible to apply only decoration without structure. Therefore they have mutual assistant relationship. A relationship can be found between hightech architecture's technology and structural symbol that Karl B tticher tried to find in steel which is new material ornament. Digital architecture can be confirmed as images which are made of maximum expose through consistent dynamics of structure. Karl Btticher try to find structural symbolism between new meterail, iron, and decoration. In modern architecture it has the closed relationship with high-tech technology.
