Y. Zheng suggested a new concept called signcryption that provides confidentiality with digital signature properties. The signcryption scheme is more efficient than general method what we call first-sign-then-encrypt of first-encrypt-then-sign in computational and communicational cost. But H. Petersen et al pointed out weakness to Y. Zheng' scheme and suggested new one. In this paper we survey three signcryption schemes suggested by Y, Zheng and H. Petersen et al respectively and cryptanalysis. M. Michel's revised scheme. And we suggest a new signcryption is more efficient when originator makes several signcryption on the same document.

Inferential structure and reality problem is a serious issue to O.M.(oriental medicine). The study will analyze this issue through a philosophical and historical comparative study of W.M.M(Western modern medicine) and O.M. First, I presuppose some basic ideas. The first is the division of the 'the philosophy of medicine' and 'the medicine itself'. Second, there is a 'visibility' that discriminate between 'the abstractive concept' and 'the concrete object' in diagnostic terminology. The third is the separation of disease, the entity and disease, the phenomenon. Finally, the distinction between the cause of disease and the nature of disease. Through these basic concepts, this study will analyze O.M's diagnostic methodology, 'Pattern identification of the S.A.S(sign and symptom)'. The results are follows: 1. O.M's views disease as a phenomenon. So, the S.A.S, which is visible, is the disease itself. Tough the analysis and inference of the S.A.S, 證(zheng) the essence is derived. 2. 證(zheng) can be considered as 'the abstractive concept' reflecting the essence of a disease. 3. 證(zheng) is not arrived through causal sequence reasoning but rather by analogical reasoning. 4. 證(zheng) is 'the non-random correlative combination of S.A.S', pattern. These patterns secure the abstractive deduction in reality. that is, The causality, the positivism, the view of disease as entity, and anatomical knowledge are the traits peculiar to W.M.M. But, these properties can not be applied universally to every medical systems. Also, these properties do not indicate the superiority or inferiority of any medical system. 5. 證(zheng) summarizes the patients condition simultaneously with the S.A.S. However, 證(zheng) doesn't necessarily indicate the knowledge about the actual internal organ. That is, Early in O.M.'s history, the diagnostic terminologies including 證(zheng) were analogical reflections of a naive knowledge of internal organs and external environmental factors. Later, the naive knowledge in 證(zheng) changed int new nature, an abstractive concept. The confusion of the concept of disease, the indiscriminate acceptance of Western anatomical knowledge, and the O.M.'s theoretical evolution et are the challenge facing modern O.M. To find solutions, this study looks at the sequence of the birth of W.M.M. and then compares it's system with the O.M. system. The confusion of the concept of disease, the indiscriminate acceptance of Western anatomical knowledge, and the O.M.'s theoretical evolution et are the challenge facing modern O.M. To find solutions, this study looks at the sequence of the birth of W.M.M. and then compares it's system with the O.M. system. It is recommended that O.M. diagnostics should pay close attention to the ambiguity of the diagnostic methodology in order to further development. At present time, the concept and the system peculiar to O.M. can not be explained by common language. but O.M.'s practitioner can not persist in this manner an: longer. Along with the internal development of O.M., the adjustment of O.M.'s diagnostic terminology needs to be adopted.

In order to find the characteristic medical methods of "BianZhengGiMun" by the author ChenShihTo, we have translated and analyzed the mentioned book. Upon analyses, the following facts were noted : 1) "BianZhengGiMun" is written and composed of case studies. Prescriptive methods described here differ rather from previously known methods, where as our nation's Oriental medicine practitioners refer and consider these methods as miraculous modern methodologies. 2) Book's content has much similarities to "ShangHanLun"'s original text. Moreover, the content is adjusted towards presenting methodologies not coverd in "ShangHanLun"'s text, together with adding more information to conserve "ShangHanLun"'s methods as well as to critique them. 3) Diagnostic methods mainly follow the ZangFuBianZheng(臟腑辨證)'s pattern, where it's recorded information and theories are valid. 4) "BianZhengGiMun"'s proscriptive methods usually follow BuYinShengJin(補陰生津)'s form, where they were appropriate for that period and circumstances. 5) In consideration of all of the above factors, ChenShihTo grasped ShangHan and WenBing(acute febrile disease due to exogenous factor) as WaiGanReBing(外感熱病)'s double sided characteristics, where this corresponds with the current belief. It is believed that this in turn would provide much practical value to the present time.

The signature-then-encryption based on RSA scheme provides forward secrecy, but requires 4 modulo exponentiation operations in total, and the signcryption scheme proposed by Zheng simultaneously fulfills both the functions of digital signature and symmetric key encryption in a logically single step, and with a computational cost significantly smaller than that required by the current standard signature-then-encryption, but it can not provide forward secrecy. In this paper, we propose an enhanced signcryption scheme which can provide forward secrecy with lower computational cost and lower communication overhead comparing with those of the signature-then-encryption based on RSA, and with a similar communication overhead of Zheng's scheme. The proposed scheme can be also easily modified to the direct signature verification scheme by the recipient without using the recipient's private key. Additionally, we suggest a new design protocol with server-supported signatures which solves the CRLs(Certificate Revocation Lists) burden and provides non-repudiation of origin. This protocol with server-supported signatures also can be applied to the original signcryption scheme proposed by Zheng in order to improve security.

Objective : The following study was undertaken in order to seek the acupuncture operation method of ${\ll}$Sang Han Lun(傷寒論)${\gg}$ Liu-Jing-Bian-Zheng(六經辨證). Methods : Based on the documents quoted in ${\ll}$Sang Hang Za Bing Lun Xu Wen(傷寒雜病論)${\gg}$ of "Zhang, Zhong-Jing(張仲景)", the relativity of the theory of Jing-Mai(經脈) and Liu-Jing-Bian-Zheng of convalescence, and from the Liu-Jing-Bing(六經病), the origin and implication that caused Tai-Yang-Bing(太陽病) to form was studied on the basis of acupuncture medicine publications and the commentary writing of ${\ll}$Sang Han Lun${\gg}$. Results : 1) ${\ll}$Sang Ham Lun${\gg}$ Liu-Jing-Bian-Zheng has succeeded and was developed based on Liu-Jing-Fen-Zheng(六經分證) of ${\ll}$Su Wen Re Lun(素問 熱論)${\gg}$. In addition the summary of Liu-Jing-Bing became the general principle of Fen-Jing(分經) and Ding-Zheng(定證) that may be applicable to Fenghan(風寒), Wenre(溫熱), Lili(疫疾) and Zabing(雜病). 2) Most commentators of ${\ll}$Sang Han Lun${\gg}$ in the Song, Ming and Ching Dynasties of ${\ll}$Sang Han Lun${\gg}$ interpreted the Tai-Yang-Bing in physiological and pathological aspects of Rong-Wei(榮衛) as the disease of the bladder meridian that oversees the skin of the human body. 3) From the Liu-Jing-Bing of ${\ll}$Sang Han Lun)${\gg}$, the region of acupuncture treatment of Tai-Yang-Bing is treated with the needle from the point of view of Bing-Zheng-Lun-Zhi(辨證論治) with the basis of the important region of acupuncture of the small intestine meridian bladder meridian and governor vessel.

Objectives : This study was performed to develop a standard instrument of oriental medical evaluation for hwa-byung. Methods : The advisor committee on this study was organized by 17 neuropsychiatry professors of oriental medical colleges. The items and structure of the instrument were quoted from the instrument of pattern identification for hwa-byung. We took consultation twice from the advisor committee and we also took additional advices by e-mail. Results : We discriminated between bian-zheng and su-zheng from the answers of the advisor committee. We got the mean weight of each symptom and sign from the answers of the advisor committee. We got the final weight from the combination of the ratio of bian-zheng to the number of all answers of the advisor committee and mean weight. Conclusions : The instrument of oriental medical evaluation for hwa-byung was developed through experts' discussion. If the validity and reliability of this instrument is confirmed through additional clinical trial, the instrument of oriental medical evaluation for hwa-byung is expected to be applied to the subsequent research.

In Dongeuibogam "東醫寶鑑", Qian Yi(錢乙)'s had been reorganized in more elaborated ways, comprising Ju dan Gae(朱丹溪)'s 'Yang is always sufficient and Yin is always deficient theory(陽有餘陰不足論) and Li Dong Yuan(李東垣)'s 'Theory of the Spleen and Stomach(脾胃論)'. In organizing the contents, 5 Organs(五臟) were mostly concerned especially 'the Heart, the Fire (心火) and the Kidney, the Water(腎水)' as the axis and 'the Spleen and Stomach(脾胃)' as the center of 5 Organs. Based on this concept, the patterns of disharmonies were categorized and the table of content was organized. In this book, 'Deficiency-Excess and Nourishing-Draining(虛實補瀉)'is the basic treatment rule and the concept of 'Yin and Yang(陰陽)' and 'Exterior and Interior(表裏)' is considered to help tell the prognosis. This book has importance of systemizing Qian Yi(錢乙)'s , which was previously mentioned in Hyangyakjipseongbang("鄕藥集成方"),Euibangyoochui("醫方類聚"), Euirimchyalyo("醫林撮要"), by comprising the theories of Jin Yuan Si Da J ia -the four great masters of the Jin Yuan Dynasties(金元四大家).
