This study aims to suggest a bag design focusing on the symbol of Bo patterns by developing a pattern-based textile which forms a Korean design with a modern sense of beauty as well as following the conventions of traditional cultures, a design which is based on the previous study on formative characteristics of Bo patterns. That is, seven pieces of motifs are considered as proper patterns that have a symbol suitable for the materials of bags, showing their individual beauty well. This includes Horomum (longevity and prosperity of desendants), Banjangmum (eternity and samsara), Jeonbomum (treasure and luck), Seobomum (innate good fortune), Bangseungmum (it means that things don't break in harmony with one another), Bomum (embroidered patches for royal family representing justice), and Seogakmum (blessed life). With these seven motifs, we developed textile patterns and printed them through DTP. Then, we created a fashion bag design with a high quality using durable canvas fabrics. Therefore, a fashion bag with the Bo patterns symbol has a propitious symbol designed with a propitious shape, not to mention its formative beauty. It is expected to have value as a fashion art item by being redesigned for benevolent patterns with a modern image.

In general, when IIR digital filter are designed from analog filters, the bilinera transformation and the impluse invariant tramsformation are commonly used. It is known, however, that high frequency response of digital filters designed by these transformations can not be well approximated to the sampled analog signals. In this paper, the symbol pulse invariant transformation is analyzed theoretically so that the symbol pulse invariant transformation which was originally application to a rectangular pulse is newly applied to double rate pulse signals and generic shape pulse signals. Also, the relation of spectra between a transfer function of digital filter and one of analog filter is considered. Further, we apply to design the digital high pass filters using the symbol pulse invariant transformation method.

This paper proposes new symbol mapping method that can enhance the performance of trellis coded M-ary PSK compared with conventional symbol mapping methods in AWGN environment. Since the basic criteria of TCM design is Maximum Euclidean distance in AWGN, conventional symbol mapping method keep this basic criteria. In this paper, proposed new symbol mapping method uses both Euclidean distance and Hamming distance to design, while conventional methods make use of only optimal Euclidean distance. New symbol mapping method show the better BER performance than the other through computer simulation and error equations.

The study is intended to clarify the ideologies and principles applied to the formative expression of church architecture which is contained both the God and human. Iconography as the relation between described target and the meaning as meaning analysis especially emphasized since the religious reason in religious art. Iconography is the area of discussing rules and habits and involved in the pieces of transition from the piece of experience obtained by sensing to the one of the ethical structure. N. L. Prak who apply meaning theory of E. Panofsky who distinguish between iconography and iconology clear relation of mental foundation which characteristics of shape of art and its concretion in architecture categorized the shape of meaning in three steps. Among them, conscious symbol and unconscious symbol correspond to iconography and iconology of Panofsky respectively. The symbol is mainly showed in religious architecture and is not related to simple practical architecture. Such symbol system can be important discussion objects in modern church architecture and necessary expressional system for expressional characteristics.

These days, universities are establishing new image; UI(University Identity) for them because of rapid change of education environment in 21st century, The objective of UI is expressing university's image externally and unifying members internally. In the process of establishing university's image, Symbol mark plays a key role in differentiating other universities because of its visual effect as well as enhancing self-confidence. In this study, I suggest that symbol mark is an important brand asset in point of differentiation and identification and analyze 36 domestic universities' symbol mark designs. In the way of this analysis, I classified these symbol marks in the aspect of shapes and colors and studied current design along with character of each symbol marks by examining usage of emblem. Therefore this paper will be used as a basic reference to understand domestic universities' symbol mark trend and to establishing differentiating strategy in the future.

The elements to enhance preference in symbol design are mainly related to consumers' response and aesthetic elements. Because certain aesthetic elements in design affect consumers' response and it is actually presented through (the different level of) preference. This study through surveying case studies examines whether a certain aesthetic element in symbol design gives rise to much preference. According to the result of study, high preference in symbolic design depends on high level of Rhythm, Balance, Harmony, Elaboration, Round, Gestalt, Organic, and Artificial/Natural among aesthetic elements. In comparison, it is founded that Simplicity/complexity, Objective/Abstract, depth, and symmetry should be designed at the moderate level, and proportion, repetition of elements be at the low level. Additionally(or Besides) this study makes out that symbol design cases with high preference have shapes from natural material or patterns of traditional culture, while cases with low preference have shapes from geometric figures. On the basis of these results, a guideline of symbol design could De offered(or suggested) to fit preference of consumers. But, this study is mostly concerned with only affect among emotional reactions of consumer in a scope of study, and is considered only in the aspect of form excluding color and texture.

This paper designs the dynamic symbol automatic trading system in Korean option market. This system is based on Multichart program which is convenient and efficient system trading tool. But the Multichart has an important restriction which has only one constant symbol per chart. This restriction causes very useful strategies impossible. The proposed design uses global variables, signal chart selection and position order exchange. So an automatic trading system with dynamic symbol works on Multichart program. To verify the proposed system, BS(Buythensell)-SB(Sellthenbuy) strategies are tested which uses the change of open-interest of stock index futures within a day. These strategies buy both call and put option in ATM at start candle and liquidate all at 12 o'clock and then sell both call and put option in ATM at 12 o'clock and also liquidate all at 14:40. From 23 March 2009 to 31 May 2010, 301-trading days, is adopted for experiment. As a result, the average daily profit rate of this simple strategies riches 1.09%. This profit rate is up to eight times of commision price which is 0.15 % per option trade. If the method which raises the profitable rate of wining trade or lower commission than 0.15% is found, these strategies make fascinated lossless trading system which is based on the proposed dynamic symbol automatic trading system.

1"his Study is to make research a Image and Symbol in the Gothic Architecture. Firstly, the concept of the symbol and the image effect are essentially based on the meaning that the activity of consciousness take on the constitution of the symbol. Therefore the image represent the deepest content of human nature has been imagination and reality. Secondly, the symbol concept showed in Gothic Architecture was associated with the passion of the order of middle ages. The world, the cosmos and the history had been revealed in Gothic architecture. In Gothic Image, Emile Male maintained the symbol of the Catholic Church as above mentioned. The Catholic Church was mirror of the natural, the institution, the moral and history, then this passion of the order was a christian order. Especially, E. Panofsky said that the scholastic method was shown in Gothic architecture. He assert that it was especially dialectic method used in theology. That is, he explained the transfiguration of Gothic Architecture with the process of thesis, anti-thesis, synthesis. These symbolize light, magnitude, clearness. Finally, symbolic image is important in Post-Modem architecture at present. Post-Modern architecture is associated with the public and the Pluralism. Post-Modern architecture attempt to communicate as symbolic language among the assumption for diverse aspect of culture.

In this paper, we consider the performance evaluation of space time block code (STBC)) with coordinate interleaved orthogonal design (CIOD) over time selective channel. In case of quasi static channel, STBC-CIOD satisfies full rate and full diversity (FRFD) property with the single symbol decoding. However in the time selective channel, the symbol interference degrades the system performance when we employ the single symbol decoding. We derive the union bound of the symbol error probability by evaluating the pairwise error probability in the first order Markov channel. We also present simulation results of STBC-CIOD with QPSK.

This paper deals with a design of a symbol timing recovery circuit of QAM using the interpolation in AWGN channel. To reduce timing jitter and the amount of processing data, we employ MGA (Modified Gardner Algorithm) as a symbol timing error detector which is called NDA(Nondecision Directed Algorithm). We show the characteristics (S-curve and the variance) of timing error detector with the roll-off factor of a shaping filter, which are compared with GA. Also, we compare the BER curve of interpolation method with that of ideal case. The performance of the STR is shown to be close to that of ideal case. This result shows that this method can be useful to implement symbol timing recovery circuit for multi-level modulation.
