  • An investigation was performed to elucidate wave character of the timber line on the middle slope of the west side of Paektusan. The Betula ermanii forest, which composes the timber line on about 2, 060m elevation of sea level, is the pure community of B. ermanii. Diffraction pattern of wave distribution of B. eramnii due to boundary condition of alpine temperature gradient was found out on the timber line. Interference patterns of waves of B. ermanii communities produced by environment conditions such as soil layers, whids, snow and relief were shown on a specific area. These facts indicate that the B. ermanii individuals have wave and particle duality, the complementarity principle.

  • This paper propose a method of shape analysis and representation for the handwritten Hangul character patterns. Each of the connected components composing a Hangul character is decomposed into many parts, and skeletons are extracted from the decomposed parts. Using the results, we represent the shape of Hangul characters using the attributed graph representation. A node of the attributed graph represents a part and an edge represents their relationships and they store valuable informations of the pattern shapes.

  • In this paper, we introduces contents about the emotion recognition and character display expressing emotion. In this paper, we proposes on things like how to search characteristic parameters expressing user emotion, how to deduce emotion through pattern matching algorithm. Also, we implemented display platform recognizing the caller's emotion over internet phone. It display character animations expressing emotion as the result deduced by emotion recognition algorithm.

  • This paper is the study about the improvement of the WPTA4 algorithm available for the recognition of various characters. The WPTA4 algorithm can extract the skeleton of a character almost similar to the original pattern by using the connection value representing connectivity of each pixel. In this paper we show that the skeleton disappearance phenomena existing in the WPTA4 and propose an modified algorithm which can eliminate this phenomena. The proposed algorithm shows that the skeleton disappearance phenomena is eliminated and the quality of extracted skeleton is excellent.

  • This study purposed to restructure representative traditional patterns formatively, manufacture actual cultural products with traditional dyeing technique using persimmon, and commercialize the results of the research. Traditionally in Korea, the dying of natural fiber such as cotton, flax and silk with persimmon was called Galmul dyeing, and clothes made through Galmul dyeing were called Galot. Galot was very useful because it is strong, does not pick up dirt easily, dries easily, and is cool in summer. In addition, cloth dyed with persimmon becomes stiff, so it does not need to be starched or ironed after washing. Moreover, it does not transmit heat under direct rays and is highly air-permeable, so it is cool and useful for standing the heat. In this study, we used traditional persimmon dyeing technique, printing traditional patterns fit for contemporary people's aesthetic sense not through dip-dying but through printing. When persimmon dyeing is used in expressing patterns, it produces not only visual effect but also embossing effect due to the characteristic of persimmon that makes printed patterns stiff, so we can obtain unique texture distinguished from other printing methods. We chose seven motive patterns, which were lotus pattern symbolizing eternal life, peony pattern symbolizing wealth and rank and prosperity, character Su(壽) pattern widely used as a symbol of health, bird and cloud pattern in the Goryeo Dynasty, Sahapyeoeuisohwa(四合如意小花) pattern printed on brocade in the Goryeo Dynasty, lattice pattern, cloth pattern on wall paintings from the Period of the Three Kingdoms. From each pattern chosen as a motive was extracted unit patterns and the original pattern was restored using Adobe Illustrator. Restored patterns were restructured to be applied to cultural products fit for contemporary formative sense. Fabrics used in dyeing were cotton, linen, ramie, silk, and polyester. Although the same persimmon dyeing was applied, we produced different feelings of patterns using various fabrics and in some cases gold and silver powder was added for the effect of gloss in addition to the embossing of patterns. Using printed fabrics we manufactured tea pads, place mats, cushions, wrapping cloth for gifts, wallet, lampshades.

  • Pattern recognition process is made up of the feature extraction in the pre-processing, the pattern clustering by training and the recognition process. This paper presents the F-LVQ (Fuzzy Learning Vector Quantization) pattern classification model which is optimized by the fuzzy membership function for the OCR(Optical Character Recognition) system. We trained 220 numeric patterns of 22 Hangul and English fonts and tested 4840 patterns whose forms are changed variously. As a result of this experiment, it is proved that the proposed model is more effective and robust than other typical LVQ models.

  • The purpose of this study was to provide effective design strategy and distinguish productions for the consumer's emotion satisfaction by analyzing formative properties of fashion sensibility and emotion. 54 photos of contemporary costume have been selected which represented the Izard' DES. The questionnaire consisted of bi-polar 25 pairs adjective scale of fashion sensibility and the 18 noun scale of emotion was distributed to 970 male and female living in Pusan area. The data were analyzed by GLM using the statistic SPSS package. The major findings of this research were as follows. 1. In the clothing formative properties following fashion sensibilities, aestheticism shows significant differences in the silhouette and texture, maturity in the silhouette and color, character in the texture and decoration and feminity in the pattern and color. 2. In the clothing formative properties following emotions, negative emotion shows significant differences in the pattern and silhouette, distressㆍfear in the silhouette and pattern, arousal in the texture and color, shame in the color and texture and enjoyment in the silhouette and pattern. 3. In the fashion sensibility and emotion following clothing formative properties, each formative property shows differences in fashion sensibility and emotion. This study result will be utilized in the clothing design development in special usage like theatrical costume, discriminated display and advertisement stratge.
