Objectives : Acupuncture manipulation, a kind of sophisticated hand movements, has been considered a fundamental skill for acupuncture practice. In this study, we aimed to develop acupuncture manipulation education system(AMES) using visual feedback of acupuncture manipulation. We also investigated whether or not acupuncture practice-$na{\ddot{i}}ve$ students could enhance their acupuncture manipulation skills after AMES training. Methods : Using AMES and motion sensor, we visualized a time-series motion template(intended motion) and participant's own motion(actual motion) manipulating an acupuncture needle. Ten students were trained with complex lifting/thrusting techniques for 8 training trials. We compared the motion pattern error of the students between the first and the last trials. Results : In our pilot experiment, half of the participants showed significantly improved manipulation skills in complex lifting/thrusting techniques after training with AMES which is developed in this study, while the other half of the participants did not show significant improvements. Conclusions : The AMES could be useful in acupuncture-manipulation training for students. Our findings suggest that novice can improve sophisticated hand movement for acupuncture manipulation with sensorimotor learning using visual feedback.

To examine the effect of biflorin, a component of Syzygium aromaticum, on memory deficit, we introduced a scopolamine-induced cognitive deficit mouse model. A single administration of biflorin increased latency time in the passive avoidance task, ameliorated alternation behavior in the Y-maze, and increased exploration time in the Morris water maze task, indicating the improvement of cognitive behaviors against cholinergic dysfunction. The biflorin-induced reverse of latency in the scopolamine-treated group was attenuated by MK-801, an NMDA receptor antagonist. Biflorin also enhanced cognitive function in a naïve mouse model. To understand the mechanism of biflorin for memory amelioration, we performed Western blot. Biflorin increased the activation of protein kinase C-${\zeta}$ and its downstream signaling molecules in the hippocampus. These results suggest that biflorin ameliorates drug-induced memory impairment by modulation of protein kinase C-${\zeta}$ signaling in mice, implying that biflorin could function as a possible therapeutic agent for the treatment of cognitive problems.

We studyed an Korean astrolabe made by Ryu Geum (1741~1788), the late Joseon Confucian scholar. It has a diameter of 17 cm and a thickness of 6 mm and is now owned by Museum of Silhak. In the 1267 of the reign of Kublai Khan of Mogol Empire, Jamal al Din, an Ilkhanate astronomer, present an astrolabe to his emperor together with 6 astronomical instruments. In 1525, an astrolabe was first made in Korea by Lee, Sun (李純, ?~?), a Korean astronomer and royal official of Joseon Dynasty. He was referred to Gexiang xinshu, a Mongloian-Chinese book by Zhao, Youqin (1280-1345), an astronomer of Mongolian Empire. This astrolabe has not been left. In the mid-17th century, an astrolabe was introduced to Joseon again through Hungai tongxian tushuo (渾蓋 通憲圖設) edited by Chinese Mathematician Li Zhi-zao (李之藻, 1565~1630), that originated from Astrolabium (1593) of Christoph Clavius (1538-1612). It seems that Ryu refered to Hungai tongxian tushuo which affect to Hongae-tongheon-ui (渾蓋通憲儀) edited by Nam, Byeong-Cheol (南秉哲, 1817~1863). We analysis lots of circles on the mother and a set of index from the rete of of Ryu's astrolabe. We find that the accuracy of circles has about 0.2~0.4 mm in average if the latitude of this astrolabe is 38 degrees. 11 indices of the rete point bright stars of the northern and southern celestial hemisphere. Their tip's accuracies are about $2^{\circ}.9{\pm}3^{\circ}.2$ and $2^{\circ}.3{\pm}2^{\circ}.8$ on right ascension and declination of stars respectively.

In the study the documents in Ryu Hee-Choon's diary (Miahm-Ilgicho) from Oct. 29th 1575 to Feb. 9th 1577, for Kaeg-Chung(客聽) are arranged and analized. Ryu, Hee-Choon (Mi-ahm) was a civil minister in the era of Myung-Jong to Sun-Jo of the Chosun dinasty. This study would be one of the basal material for actually inquiring into the character of houses for the gentry in the late 16th century. Above all, the significance of this is that it study could show the details of the architectural economy, the organization of architectural society and the process of the supply of architectural material at that time. Craftsmen devoting themselves to this work are carpenters, artisans making roof titles, roofers and artisans constructing walls. And the content that are craftsmen of monks(僧匠), artisans of commoners(私匠) and slaves belong to government(官奴) is noticeable thing. In this construction work, monks in temples of the region and laboures commandeered by the government office are mainly mobilized. Except of them, private slaves and commoners mobilized by government office also devoted themselves to this work. But, it required more research whether this aspect could be the general character of the construction work of the gentry in the late 16th century. Architectural material, in the case of wood was cut and transported mostly from islands like Jin-do by labourers commandeered by the head officer of the region and monks. Superintendents seemed to come be non-specialists of noble families of the ruling class. So, it is thought that they managed mainly the manpower supply and administration. And some architectural ironworks, much provisions and marine products for labourers and craftsmen were proided by the government office of the region. This could be understood in the same context as above that goverment office of the region contributed to commandeering labourers and supplying architectural material in some degree. Carpenters and roofers took wages that is, about 7.7 pils(匹) of cotton cloth for each carpenter and 5 pils of cotton cloth and some provisions for each roofer. This would be a noticeable thing for researching wages of craftsmen at that time

With Seopa Ryu-Hee's Chunqiugwalyebulyu as the main research subject. this paper is to clarify characteristics in classification of the book's introductory remarks and its academic values. This book is a sort of synthetic collection of introductory remarks classification that defines standardized introductory remarks based on fundamental principles of Chunqiu introductory remarks. Seopa presented two fundamental principles for classifying Chunqiu introductory remarks. First, he clearly defined the nature and the system of the book Chunqiu, which was to present the background of classifying Chunqiu introductory remarks. Second, he declared that writing style and righteousness in Chunqiu serves as standard for classifying the introductory remarks. Seopa classified introductory remarks by type in accordance with these fundamental principles of introductory remarks in order to lay the groundwork for right interpretation of Chunqiu. Further, he was convinced that this classification of introductory remarks would block any chance of the book's wrong interpretation and at the same time, be able to remove the rationale behind distorted theories. This book can be appraised to have significant academic values in that it attempted standardization in classifying Chunqiu introductory remarks through systematic and synthetic analysis on various introductory remarks.
