Recently, many researchers have been interested in biometric systems such as fingerprint, handwriting, key-stroke patterns and human iris. From the viewpoint of reliability and robustness, iris recognition is the most attractive biometric system. Moreover, the iris recognition system is a comfortable biometric system, since the video image of an eye can be taken at a distance. In this paper, we discuss human iris recognition, which is based on accurate iris localization, robust feature extraction, and Neural Network classification. The iris region is accurately localized in the eye image using a multiresolution active snake model. For the feature representation, the localized iris image is decomposed using wavelet transform based on dyadic Haar wavelet. Experimental results show the usefulness of wavelet transform in comparison to conventional Gabor transform. In addition, we present a new method for setting initial weight vectors in competitive learning. The proposed initialization method yields better accuracy than the conventional method.

본 논문은 개발하고자 하는 기계학습 기반 한글 필기 인식 시스템의 첫 연구 결과를 담고 있다. 즉, 기계학습을 위해서는 학습용 및 테스트용 필기 데이터가 아주 많이 필요하므로, 이를 수집하고 전처리하는 방법을 제안하였다. 한글의 한 글자는 자음과 모음을 결합하여 생성되는데, 실제 만 개 이상의 글자가 생성될 수 있다. 따라서 각각의 글자 데이터를 수집하는 대신, 수집한 글자 데이터로부터 초성, 중성, 종성을 구분하여 최종적으로 자음, 모음 데이터로 저장하고자 한다. 아직 초기 연구이므로, 다양한 경우에 대한 분석이나 실험 결과는 없지만, 이를 활용하여 온라인 필기 인식 모델에 적용하여 인식 성능을 높이기 위한 추후 연구의 기반으로 활용하고자 한다.

"Japji" was an old cookbook written in 1721. There are 27 types of foods recorded in "Japji"; 10 descriptions of Byeonggwaryu (rice cakes and cookies): Yakgwa, Junggye, Mandugwa, Chaesugwa, Umujeonggwa, Dongajeonggwa, Baekjapyeon, Aengdupyeon, Toranbyeong, and Yeot; and 16 descriptions of Chanpumryu (side dishes): Jinjumyeon, Jeunggyetang, Geumjungtang, Eoreumtang, Changjajjim, Gajijjim, Oejjim, Dubuseon, Dubuneureumi, Geneureumi, Gesanjeok, Hodojaban, Jeonyak, Seokryutang, Sungeojuak, and Yangmandu. There is also a description of Gugija (Chinese wolfberry) liquor. Here, comparative analysis based on culinary science was carried out on the Korean foods recorded in "Japji" as well as the similar foods recorded in "Gyuhapchongseo" (Women's Encyclopedia) written around 1815. Of the 27 types of Korean foods recorded in "Japji", 13 were also found recorded in "Gyuhapchongseo". The time period for "Japji" can be assumed to be 1721 based on the fact that it is written in a cursive handwriting style of Hangeul, that chili was never used as an ingredient, and that the word "Shinchuknyeon (辛丑年)" was transcribed at the beginning of the book. The dating method also included considerations of whether Neureumi was used or not as well as changes in its cooking style.

This study will explore the application of the Korean alphabet 'Hangul' and its calligraphy on fashion design. Hangul is well known for its great formative characteristics. Its calligraphy has unique features that express the implicative meaning of the Korean language while simultaneously displays beautiful shapes that draw the viewer's eye. When Hangul calligraphy is applied on the pattern design, it can be an excellent opportunity to demonstrate the visual beauty of Hangul. The purpose of this study is to develop the pattern designs that utilize the Hangul calligraphy and apply them in various fields of fashion. The detailed concepts of this study are as follows. First, the theoretical concepts and characteristics of both Hangul calligraphy and pattern design will be understood. Second, the aesthetic characteristics of calligraphy will be drawn by case analysis on the artworks of famous calligraphers such as Kim Jong-geon, Kang Byeong-in, Lee Sang-hyeon, Lee Gyu-bok and other representative calligraphers who design the beauty of Korean calligraphy by handwriting and brush-writing. The obtained results will be used to explore the desirable direction of fashion design. Third, eight pattern motif fashion works that utilize Hangul calligraphy in accordance with the arrangement of different characteristics of fashion design will be presented.

This study is purposed to list the full translation of "The secret method of tumor treatment(治瘇方)" and to report the results to the academic world. The results are described as follows. 1. It seems to be difficult to accept the current "The secret method of tumor treatment(治瘇秘方)" as the original script of "The method of tumor treatment(治瘇方)". It seemed that the Imeonguk(任彦國)'s 'Important and Valuable Method(遺方)' at the era of Joseon was copied by handwriting among the private sector. 2. There are contents which are overlapped with "Experience Method of Acupuncture(針灸經驗方)". A further study is required whether the "Experience Method of Acupuncture" was added later on. Because resolution for the before and after of these two books may be acted as an important matter to conjecture the related schools with acupuncture science. 3. The Korean style unique method and terminology were introduced frequently in "The method of tumor treatment". Besides that, materials for the medicine were filled with the things of easy-to-contact in our daily life. It is regarded as one of the excellent materials to confirm the superiority of oriental medical science through the clinical experiments today.
