  • Objectives & Methods: This study was aimed to investigate denomination and distribution of fifteen main collaterals through oriental medicine literature. Results & Conclusions: 1. Kyung-maek-pyoun(經脈篇) of Yeong-chu (靈樞; divine pivot) says that fifteen main collaterals (十五絡脈) consist of main collaterals of the twelve regular meridians (十二經脈), Conception Channel (任孤), Governor channel (督脈) and great collateral of the spleen(脾之大絡). While chapter 26 of Nan-gyung(難經; Classic of difficulty) says that Yin-heel & Yang-heel channels are included instead of Conception channel(任脈) and Governor Channel (督脈). what is explained in Yeong-chu (靈樞; divine pivot) is considered more proper. 2. Great collateral of the stomach (胃之大絡 ) has been considered as one of the main collaterals, resulting in an opinion of sixteen main collaterals. We speculate that this is a wrong interpretation of Pyoung-in-gi-sang-lon(平人氣象論 ) of So-mun(素問). 3. Gumi (CV1) is more resonable than Hoeeum(CV14) for the Connecting point of Conception Channel(任脈) 4. Kyung-maek-pyoun (經脈篇) of Yeong-chu (靈樞; divine pivot) did not mention that the collateral of Hand Jueyin (手厥陰絡版) was running to Hand Shaoyang(手少陽經脈), which is considered to be omitted by mistake. 5. Fifteen main collaterals are mostly distributed on the legs and arms, while some are distributed in the internal organs, chest, abdomen, as well as head and five sensory organs.

  • Electronic and telecommunication industries are constantly striving towards miniaturization of electronic devices. Miniaturization of chips creates extra space on PCBs that can be populated with additional components, which decreases the heat transfer surface area and generates very high heat flux. Even though an air-cooling technology for telecommunication equipment has been developed in accordance with rapid growth in electrical industry, it is confronted with the limitation of cooling capacity due to the rapid increase of heat density. In this study, liquid-cooling heat exchangers were designed and tested by varying geometry and operating conditions. In addition, air-cooling heat exchangers were tested to provide performance data for the comparison with the liquid-cooling heat exchangers. The liquid-cooling heat exchangers had twelve rectangular channels with different flow paths of 1, 2, and 12. Silicon rubber heaters were used to control the heat load to the heat exchangers. Heat input ranged from 293 to 800W, and inlet temperatures of working fluid varied from 15 to $27^{\circ}C$. The heat transfer coefficients were strongly affected by flow conditions. All liquid-cooling heat exchangers showed higher cooling performance than the air-cooling heat exchanger. The heat exchanger with 2-paths could provide more controllability on the maximum temperature than the others.

  • The heat transfer performance and energy transport ability are relatively high due to higher specific heat. Therefore, it can be used in fields such as heating, ventilating, air-conditioning, refrigeration and heat exchangers. In this study, liquid-cooling heat exchangers were designed and tested by varying geometry and operating conditions. In addition, liquid-cooling heat exchangers were tested to provide performance data for MPCM slurry. The liquid-cooling heat exchangers had twelve rectangular channels with flow paths of 1, 2, 4 and 12. Silicon rubber heaters were used to control the heat load to the heat exchanger. Heat input ranged from 293 to 800 W, and inlet temperatures of working fluid varied from 15S to $27^{\circ}C$. The standard deviation of surface temperature was strongly affected by the coolant of MPCM Slurry, All MPCM-cooling heat exchangers showed higher cooling performance than the water-cooling heat exchanger except one path channel heat exchanger.

  • In this paper, we propose an image compression scheme which uses a demosaicking network and a channel-wise decoder in the decoding network. For the demosaicing network, we use as the input a colored mosaiced pattern rather than the well-known Bayer pattern. The use of a colored mosaiced pattern results in the mosaiced image containing a greater amount of information pertaining to the original image. Therefore, it contributes to result in a better color reconstruction. The channel-wise decoder is composed of multiple decoders where each decoder is responsible for each channel in the color image, i.e., the R, G, and B channels. The encoder and decoder are both implemented by wavelet based auto-encoders for better performance. Experimental results verify that the separated channel-wise decoders and the colored mosaic pattern produce a better reconstructed color image than a single decoder. When combining the colored CFA with the multi-decoder, the PSNR metric exhibits an increase of over 2dB for three-times compression and approximately 0.6dB for twelve-times compression compared to the Bayer CFA with a single decoder. Therefore, the compression rate is also increased with the proposed method than with the method using a single decoder on the Bayer patterned mosaic image.

  • Objectives : Ten heavenly stems(10天干) and Twelve earthly branches(12地支) are symbols exposing change order in heaven and earth, and are a very important sign in studying oriental philosophy and oriental medicine. Especially, 10 heavenly stems(10天干) and 12 earthly branches(12地支) are indispensable for the study of Five Circuits And Six Qi(오운육기), and a deep study is needed. Methods : I have examined Yin Yang combination(음양배합), Five elements combination(오행배합), Six Qi 3Yin 3Yang combination(육기삼음삼양배합), viscera combination(장부배합), Mutual collision(상충), Six combination(육합), Three combination(삼합), etc. of 12 earthly branches(12지지) by referring to books such as "Yellow Emperor Internal Classic" ("黃帝內經") and "Principle of universe change" ("우주변화의 원리"). Results & Conclusions : Zi Yin Chen Wu Shen Xu(子 寅 辰 午 申 戌) become Yang(陽), Chou Mao Si Wei You Hai(丑 卯 巳 未 酉 亥) become Yin(陰), Zi Si Yin Mao Chen Si(子 丑 寅 卯 辰 巳) become Yang, and Wu Wei Shen You Xu Hai(午 未 申 酉 戌 亥) become Yin. Twelve earthly branches can be divided into five movements by its original meaning, where YinMao(인묘) is tree, SiWu(사오) is a fire, ShenYou(신유) is a gold, HaiZi(해자) is water, and ChenXuChouWei(진술축미) mediate in the middle of four movements So they become soil(土). SiHai(巳亥) is JueYin Wind Tree(궐음 풍목), ZiWu(子午) is ShaoYin Monarch Fire(소음 군화), ChouWei(丑未) is TaiYin Humid Soil(태음 습토), YinShen(寅申) is ShaoYang Ministerial Fire(소양 상화), MaoYou(卯酉) is YangMing Dry Gold(양명 조금), and ChenXu(辰戌) is TaiYang Cold Water(태양 한수). Viscera combination(장부배합) combines Zi(子) and Bile(膽), Chou(丑) and Liver(肝), Yin(寅) and Lung(肺), Mao(卯) and Large intestine(大腸), Chen(辰) and Stomach(胃), Si(巳) and Spleen(脾), Wu(午) and Heart(心), Wei(未) and Small intestine(小腸), Shen(申) and Bladder(膀胱), You(酉) and Kidney(腎), Xu(戌) and Pericardium(心包), Hai(亥) and Tri-energizer(三焦), Which means that the function of the viscera and channels is the most active at that time. Twelve earthly branches mutual collisions collide with Zi(子) and Wu(午), Chou(丑) and Wei(未), Yin(寅) and Shen(申), Mao(卯) and You(酉), Chen(辰) and Xu(戌), and Si(巳) and Hai(亥). The two colliding earthly branches are on opposite sides, facing each other and restricting each other by the relation of Yin-Yin and Yang-Yang it rejects each other so a collision occurs. Six Correspondences(六合) coincide with Zi(子) and Chou(丑), Yin(寅) and Hai (亥), Mao(卯) and Xu(戌), Chen(辰) and You(酉) and Si(巳) and Shen(申) Wu(午) and Wei(未). Three combination(三合) is composed of ShenZiChen(申子辰), SiYouChou(巳酉丑), YinWuXu(寅午戌), and HaiMaoWei(亥卯未). Three combination(三合) is composed of ShenZiChen(申子辰), SiYouChou(巳酉丑), YinWuXu(寅午戌), and HaiMaoWei(亥卯未). This is because the time Six Qi(六氣) shifts in these three years are the same.

  • We came to the conclusion as follows from the research about pulse diagnostic technique (脈診) out of "Nan Jinghoeju jeonjung" (難經滙注箋正). 1. "Nan Jing" is practical medical book for clinician and holds different opinions about three portions and nine takings(三部九候脈法) from Huang Di Nei Jing's Taking the pulse of Bu Jung Chim Chon Kwan Chuk((浮中沈 寸關尺) is a quite creative means which has been a important role to future generation. 2. We pointed the differences between western medical science and traditional medical science. And can explain the pulse in western medicine divided from twelve channels of Oriental Medicine. We can explain special connection between heart and lungs using the theory of systemic & pulmonary circulation in western medicine. And this can be a basement of Lung controls every pulse theory in oriental medicine. 3. We have negative assertion about viewing the human body using theory of Yin and Yang-Five Elements. And have poor opinion of explaining about the matching internal organs to Chon Kwan Chuk using the theory of Yin and Yang-Five Elements. 4. We pointed out the mistake that Porak & Sang hwa act for heart. We took pulses considering heart is a real actual internal organ as others. 5. We denied the theory of Man's Chuk pulse is always weak(男子尺脈恒弱) & Woman's Chuk pulse is always strong(女子尺脈恒盛). The physical form of man and woman is not different from each other considering their inheritances from forefather & same shape of organs. So, we cannot insist on the theory.

  • Three burning space concentrating mainly on the text of ${\ll}NeiChing{\gg}$, we got this conclusion by looking at a longitudial perspective of three burning space function, nutrient & defensive qi creation, movement and numbers. 1. Longitudial movement is the law of the universe, by looking at oriental medicine by the thought of heaven and man unity we can tell that longitudial movement concept is used to analyze the physiology of our body. And we can look at our body in a cubic movement suck as top and bottom, left and right, outside and inside, internal and external, upward and downward movement. 2. In Nei Ching the concept of three burning space is seperated in to four different types of three burning space which are three burning space as a fu, three burning space as a water metabolism and excretion organ, and three burning space by its position. 3. nutrient & defensive qi's movement in the channel is the same as the twelve regular channels movement in our body, nutrient qi circulates the yang part twenty five during the day and circulates the ying part twenty five times during the night. Since channel functions corresponds with the sun, moon, and the stars the ups and downs of nutrient & defensive qi's property varies with the difference of the periods. 4. By comparing nutrient & defensive qi's production and property with three burning space's positional property, we can see that three burning space's positional property comes out from the longitudial movement of nutrient & defensive qi.

  • When people discuss the continental cultural elements in the ancient East Asian culture, people always attach great importance to the two major cultures of Confucianism and Taoism, but offer little explanation to the significant influence of the theory of yin and yang, the important philosophical base of the two major cultures. The theory of yin and yang, existing as the theoretical source at a profounder level, possesses philosophical connotations that are always embedded into the mainstream of thought, religions and customs, displaying its unique glamour in its unique way. Its influence is more than that, however. It has exerted far-reaching influence on and is of significant importance to the development of the ancient culture of East Asia. This article aims at exploring this field of study. After the erudite scholar of The Five Classics made a voyage to the east in the early sixth century, The Book of Changes, the most important Chinese ancient classic expounding the theory of yin and yang, started to circulate among the Japanese court, via Baiji in the Korea Peninsula. As a result, the theory of yin and yang found its way to Japan. Examining the spreading channels, we learn that the theory's dissemination was largely related to the activities of Buddhist monks. Shoutoku Prince, regent of Japan at the time, was himself an enthusiastic supporter of Buddhism and was excelled in the study of The Book of Changes and the theory of yin and yang. In the Twelve Ranks System and Seventeen-article Constitution promulgated by Shoutoku Prince, the influence of the theory of yin and yang and of the theory of the five elements can be visibly discerned. This obviously proves the sublime status of the Chinese theory of yin and yang in Japan, thanks to the victory of the political clique that adored Buddhism. In the shaping course of ancient Japanese culture, the theory of yin and yang served as an important philosophical source of its development. Mythology based on Kojiki and Nihon Shoki, two earliest Japanese books that exist today, record mythological stories about the emergence of the Japanese nation. The notion about the birth of heaven and earth and the forming of Japanese Shinto, expressed in the mythological stories, not only tell us the source and historical progress of the Japanese nation but also the nation's world outlook in the transition from barbarian period to civilized period, as well as the basis for its philosophical thinking. All these were marked with profound influence of the Chinese theory of yin and yang. The theory of yin and yang, as one of the ancient Chinese academic thoughts, was accepted asa political belief when it first spread to Japan. The emergence and establishment of both the Mikado system and the centralized regime in ancient Japan drew largely on the theory of yin and yang and adopted it as an important philosophical basis to deify and aggrandize the "imperial power" so as to protect the authority of the imperial ruling and consolidate the established regime. Following the continuous strengthening and expansion of the centralized state power, the theory of yin and yang was further employed, and gradually "hidden" in Japanese culture with the passage of time, finally becoming the edge tool of ancient Japanese Mikados in exercising political power and controlling the country.
