Due to the rapid development of mobile devices equipped with cameras, instant translation of any text seen in any context is possible. Mobile devices can serve as a translation tool by recognizing the texts presented in the captured scenes. Images captured by cameras will embed more external or unwanted effects which need not to be considered in traditional optical character recognition (OCR). In this paper, we segment a text image captured by mobile devices into individual single characters to facilitate OCR kernel processing. Before proceeding with character segmentation, text detection and text line construction need to be performed in advance. A novel character segmentation method which integrates touched character filters is employed on text images captured by cameras. In addition, periphery features are extracted from the segmented images of touched characters and fed as inputs to support vector machines to calculate the confident values. In our experiment, the accuracy rate of the proposed character segmentation system is 94.90%, which demonstrates the effectiveness of the proposed method.

Chang Chung-ching(張仲景) in the Later Han(Eastern Han) Dynasty of Chinese history wrote the treatise on Diseases Caused by Cold Factors(傷寒論; Shang Han Lun) on the basis of the fundamental theory of Emperor's Classic of Internal Medicine(黃帝內經; ECIM) after collecting medical treatment experiences until the Han Dynasty. It had great significance that Shang Han Lun was the origin of treating six-channels(六經) and there showed the peculiar guidelines on the diagnosis and treatment of oriental medicine to divide diseases into six-channels. The oriental medical doctors who had studied Shang Han Run thought highly of meridians and until now it was generally known that the chapter of heat in the Plain Questions of ECIM(黃帝內經, 素問ㆍ熱論) was the basis of Shang Han Run. The chapter of heat in the Plain Questions of ECIM was the first text in which the basic theory on six-channels according to the types of illness was introduced. In my point of view, the theory of treating six-channels had close relation to the Chapter of Channels in Miraculous Pivot of ECIM(黃帝內經, 靈樞ㆍ經脈篇) as well as the chapter of heat in the Plain Questions of ECIM. Therefore I took a look at the origin of treating six-channels in Shang Han Lun and illuminated again the meaning to compare the parts of in Shang Han Lun with the Chapter of Channels in Miraculous Pivot of ECIM. Conclusion: The, symptoms divided into six-channels in the chapter of channels in ECIM gave the fundamental basis of diagnosis and treatment basesd on overall analysis of signs and symptoms(辨證論治) an illness in the Zangfu(臟腑) in respect of meridians. Viewed in the light of diagnosis and treatment basesd on overall analysis of signs and symptoms(辨證論治), the symptoms of YangMing-channel(陽明經) in the Chapter of Channels in Miraculous Pivot of ECIM were, for the most part, accord with those of YangMing-disease in Shang Han Lun. Furthermore, the symptoms in Shang Han Lun were explained definitely and in detail. Therefore the theory of Shang Han Lun has been developed on the basis of ECIM with the changes of the times. YangMing-disease in Shang Han Lun implied medical cases in stomach meridian(胃經) and large intestine meridian(大腸經). Therefore Shang Han Lun was the foundation of treatment basesd on overall analysis of signs and symptoms(辨證論治) in respect of meridian as well as the text in which the steps of infectious diseases(外感病) of human bodies were explained.

We considered the context of the publications and transmissions of mathematics books using the Korean traditional book lists and the catalogues of woodblocks in the Joseon Dynasty and DaeHan大韓 Empire period. Among the results, this paper first describes the context of the publication and transmission of mathematics textbooks of national math exams算學取才 in the first half of Joseon, adding a step more specific to the facts known so far. In 1430, 『YangHui SanFa楊輝算法』, 『XiangMing SuanFa詳明算法』, 『SuanXue QiMeng算學啓蒙』, 『DiSuan地算』, 『WuCao SuanJing五曹算經』 were selected as the textbooks of national math exams算學取才. 『YangHui SanFa』, 『XiangMing SuanFa』, 『DiSuan』 were included in the catalogues of woodblocks in the Joseon Dynasty before the Japanese invasion in 1592, and we could see that Gyeongju慶州, Chuncheon春川, and Wonju原州 were the printing centers of these books. Through other lists, literature records and real text books, it came out into the open that 『XiangMing SuanFa』 was published as movable print books three times at least, 『SuanXue QiMeng』 four times at least in the first half of Joseon Dynasty. And 『XiangMing SuanFa』 was published at about 100 years later than 『YangHui SanFa楊輝算法』 as xylographic books, 『SuanXue QiMeng』 was published twice as xylographic books in the second half of Joseon Dynasty. Whether or not the list of royal books included the Korean or Chinese versions of these books, and additional notation in that shows how the royal estimation of these books changed.

Compared to hiding information into digital image, hiding information into digital text file requires less storage space and smaller bandwidth for data transmission, and it has obvious universality and extensiveness. However, text files have low redundancy, so it is more difficult to hide information in text files. To overcome this difficulty, Wang et al. proposed a reversible information hiding scheme using left-right and up-down representations of Chinese characters, but, when the scheme is implemented, it does not provide good visual steganographic effectiveness, and the embedding and extracting processes are too complicated to be done with reasonable effort and cost. We observed that a lot of traditional and simplified Chinese characters look somewhat the same (also called lookalike), so we utilize this feature to propose a novel information hiding scheme for hiding secret data in lookalike Chinese characters. Comparing to Wang et al.'s scheme, the proposed scheme simplifies the embedding and extracting procedures significantly and improves the effectiveness of visual steganographic images. The experimental results demonstrated the advantages of our proposed scheme.

This paper suggested MyeonGu(面垢), symptom of Baekho-tang(白虎湯) in text 219 of Shang-Han-Lun(傷寒論), could be reinterpreted. There were 4 cases, 1 case on atopic dermatitis and 3 cases on psoriasis. All of them were diagnosed by Ying-Ming-Bing(陽明病) symptom. After taking Baekho-tang, SCORAD index of atopic dermatitis in case 1 improved 62.8 to 12.8 and PASI score of psoriasis in case 2, 3, and 4 improved 13.0 to 2.4, 10.8 to 0.8, and 8.6 to 1.0 respectively. Since Baekho-tang was effective for certain skin disease with Ying-Ming-Bing(陽明病) symptom, MyeonGu could be related on skin problem. MyeonGu was mainly translated in 'someone's face seems to be covered with dirt'. However if Myeon(面) is translated in 'surface of the body' and Gu(垢) is translated in 'inflammation', it means the surface of the body suffered from papules, erythema, white scales, etc. These are features of chronic inflammatory cutaneous disease like atopic dermatitis and psoriasis. This study is meaningful in case of giving specific clinical case of MyeonGu of Baekhotang text of Shanghanlun.

This study aims to take a look at the ShinKanMyungYiJapZhe(新刊明醫雜著)'s publication process, influence on later generations, and its historical significance. A publication of the Ming dynasty, MyungYiJapZhe(明醫雜著) was republished by ChoSung(趙晟), a Chosun Confucian doctor, in 1551. In the process of its republication, the clinical value of this text was proven, and further explanations on ambiguous topics were also added. . A Japanese book based on the Chosun ShinKanMyungYiJapZhe(新刊明醫雜著) was discovered in the process of this research, and an analysis of this book also took place. Through the above research it could be shown that the Chosun republication of Chinese medical texts was an important means of medical information exchange and that through such processes new medical knowledge could be created.

This paper is focused on the 'contents' of database level medical texts sponsored by the Chinese government. The premise of the study is that the contents of state-sponsored medical texts would show how medical policy makers and practitioners approached the body and diseases of the time, and by association the medical text would reveal the policy associated with state medical education and distribution of medical resources associated with the practitioners' approaches. This paper analyzes the contents of four representative state-sponsored medical texts: Cao's Treatise on the Origins and Symptoms of Various Diseases (巢氏諸病源候論, 610, Sui China); Great Peace and Sagely Benevolence Formulas (太平聖惠方, 996, Song China); Complete Record of Sagely Benevolence (聖濟總錄, 1117, Song China); Formulas for Universal Relief (普濟方, 1406, Ming China).

Objectives :This paper analyzes the newly discovered manuscripts of the Sanghanjijangdo(傷寒指掌圖). A bibliographic study was carried out to examine the contents and the background of publication. Methods : First, a bibliographical analysis of the Joseon text was conducted. Next, the contents of the composition were compared with the Yuanand early Ming publications of China. Results : 1. The Joseon publication was published based on the original publication from the Yuan period. The Sanghanjijangdo has been cited in several medical texts from early Joseon such as the Euibangyuchwi and Hyangyakjipseongbang. 3. The background for publication of the Sanghanjijangdo is as following. First, it is an introductory text for beginners of Shanghan[cold damage] studies. Second, its contents do not conflict with the specialized Shanghan text that was used as the textbook for the royal physician examination. Third, it contains many Shanghan formulas that could be composed of domestic drugs only. Conclusions : The Sanghanjijangdo could be described as an introductory text for beginners of Shanghan studies that contributed to the expansion of the base of Shanghan studies in 15c mid-Joseon. Publication of this book clearly shows that Shanghan studies in early Joseon was practiced within the scopes of practicality and localization of medicinals.
