Terahertz waves are superior to conventional X-ray or Magnetic Resonance Tomography(MRI), and the amount of information that can be transmitted is as large as thousands of times that conventional X-ray or MRI. In addition, Terahertz waves have great performance in analyzing an object which have some layered structure. By using this advantage, we can extract the letters of a page by analyzing information such as absorption amount and reflection amount by irradiating a closed book with pulses of various frequencies within gap of a terahertz wave. However, in the image of each page using the Terahertz wave might be obtained various kinds of noise and the different character occlusion region. So, to extract letters from the terahertz image, we must take the noise and occlusion region away. We have been working to enhancement the image quality in various ways, and keep on studying de-noising processing for enhancement about the image quality and high resolution. Finally, we also keep on studying about OCR(Optical Character Recognition) technology, which based on pattern matching technique, to read letters.

This study is to explore the usability of a pattern making software 'Looks tailor X' developed recently by the Digital Fashion in line with the cloth simulation software 'DressingSim'. When the software engineers develop software for clothes and clothing simulations, most often they lose touch of real-world craftsmanship of pattern making. As such, the software evaluation of the functionality and the usability is a crucial step in the field of virtual clothing. We carried out a detailed evaluation of the software via the process of making some basic types of pattern including tight skirts, pants, jackets, and one-piece dress. In this paper, we documented a step-by-step scenarios of making clothes using the Looks tailor X, and listed both the advantages and limitations of the software from the perspective of an enduser, i.e., a professional fashion designer. We also briefed suggestions on the refinement of the future software in the field.

This study was developed using the DTP (digital textile printing) jacquard fabrics with a three-dimensional pattern for bag and evaluated the preference and emotional structure. The following conclusions were obtained. Three-dimensional patterns of 12 species using the illustrator program, including six kinds of designs based on the text and six kinds of character types based on the geometry of the basic design was developed. As a result of evaluating the preference of the three-dimensional pattern jacquard fabric, the most preferred fabric was a three-dimensional patterned jacquard fabric with a motif of the Korean consonant "ㅅ". The results of analyzing the emotional dimension of the three-dimensional pattern jacquard fabric, eight factors including simple image, feminine image, exotic image, graphic image, sporty image, masculine image, dynamic image and stereoscopic image were derived. Between emotional factors and preferences correlation analysis showed the stronger the simple image, the feminine image, and the sporty image, the more preferable. It suggested the possibility of a morphological and new fabric for bag, textile design motifs by using Hangul consonants attempt to limit the flatness of the existing geometric form patterns that can be applied to three-dimensional bag whether swirly patterns overcome.

Patterns abstractly depicting flowing water with Chinese characters such as gong, wan(man), or wang continued endlessly and curved water patterns began appearing on textiles during the Song Dynasty. Though Song curved water patterns encompassed poetic sentiments such as "falling flowers and flowing water," the meaning faded with time, and these patterns were depicted in backgrounds with flowers added to brocade (Geum-sang-cheom-hwa). During the Ming and Qing Dynasties, combinations of diverse patterns, including flowers, butterflies, dragons, and auspicious treasures became fashionable, rather than the gong- and wan-shaped curved water patterns. Likewise, during the Joseon Dynasty, curved water patterns were preferred as background rather than as primary patterns. They were overlaid with flowers and clouds. The overlaid flower patterns included four-season flower patterns (17th-18th centuries), round flower patterns (19th century), and large flower patterns (20th century), which were identical to flower patterns fashionable at the time and arranged at intervals on complex curved water pattern backgrounds. In contrast, simple Ruyi types were more numerous than the four-Ruyi types fashionable at the time with regard to cloud patterns. Added here were Taiji (great ultimate symbol) or crane patterns, thus seeking to depict diverse auspicious Ruyi such as wish fulfillment and longevity.

The purposes of this study are to review the Chinese traditional patterns and to apply one of them, the Peony Blossom pattern into modern textile designs for fashion For this purpose, first, the categories and symbolic meanings of the patterns existing in the Chinese traditional clothing from literature were reviewed. Second, the Peony Blossom patterns of Chinese traditional patterns from literature were reviewed and selected one of them, Third, authors applied the Peony Blossom pattern to creative textile design which would fit to appetite of people lived in modern society. The results were as follows: The patterns of Chinese traditional clothing could be classified as animal pattern, plant pattern, nature pattern, character pattern, lucky token pattern, geometric pattern and so on. All these patterns contained individual symbolic meaning, which varied according the different wearers. Moreover, it endows a peony blossom pattern of Chinese traditional patterns with modern style and purposes the textile design. The theme of the design is "Luxuriant Outing" with the concept of "Dream in Fantasy". The design target is the female born in the 1980's, that is, the target population between 20 and 30 years old. In addition, it is designed for the romantic one-piece. This paper perceives the national spirit revealed in the Chinese traditional patterns and designs with the combination of traditional culture and modernized technique of expression.

The operator LIKE of the database language SQL is a string pattern search operator. By providing the string pattern, the operator can identify column values that match with the string pattern. As a phonetic symbol, each Korean syllable is composed either of a leading sound and a medial sound or of a leading sound, a medial sound, and a trailing sound. As a search pattern of Korean syllables of the operator LIKE, in addition to the traditional Korean search pattern, this paper proposes a new search pattern that is based on leading sounds and medial sounds of Korean. With the new Korean search pattern, Korean syllables having specific leading sounds, specific medial sounds, or both specific leading sounds and medial sounds can be found. Formulating predicates equivalent with the new Korean search pattern by way of existing SQL operators is cumbersome and might cause the portability problem of applications depending on the underlying character set of the DBMS. This paper presents algorithms for the execution of the operator LIKE considering the new Korean search pattern based on the characters that are represented in KS X 1001, which is a Korean standard code for information interchange of Korean and Chinese.

The most popular speech feature used in speech recognition today is the Mel-Frequency Cepstral Coefficients (MFCC) algorithm, which could reflect the perception characteristics of the human ear more accurately than other parameters. This paper adopts MFCC and its first order difference, which could reflect the dynamic character of speech signal, as synthetical parametric representation. Furthermore, we quote Dynamic Time Warping (DTW) algorithm to search match paths in the pattern recognition process. We use the software "GoldWave" to record English digitals in the lab environments and the simulation results indicate the algorithm has higher recognition accuracy than others using LPCC, etc. as character parameters in the experiment for Digital Isolated Word Recognition (DIWR) system.

This study aims at advancing waterfront of Pusan Port and attempting to establish an identity through studying characteristics of place in Pusan Port. The place is consisted of two elements ; orientation and identity, which is expressed clearly the environmental totality including the character and space. The urban waterfront is also one of the place pattern, and that is consist of land area, water area, and transit zone combining two areas. Although there are a lot of primary factors to be able to make the most of the character and identity in Pusan port, badly planned development prevents the plan promoting the sense of place in urban waterfront. The point in the waterfront development plan of Pusan Port is how to secure aminities based on Identity and Orientation; node, landmark, edge, path, district. The result of this study is for planners to develop more and systematic approaches which could utilize waterfront.
