Objectives : To study the shu points selection of the Four Seas in the 「Hailun」 chapter of 『Lingshu』. Methods : The effects and main indications of each shu point, their anatomical position, characteristics along with similarities of disease patterns according to excessiveness and deficiency of the Four Seas were examined. Results : The selection of shu points of the Four Seas were deeply related to the effects and main indications, and the common similarity among conditions due to excessiveness and deficiency was the presence of psychological aspects. Also, when the Four Seas are connected to the Jing-Qi-Shen and Blood, marrow sea[髓海] is connected to Jing & Shen, qi sea[氣海] is connected to Qi, blood sea[血海] is connected to Blood, and sea of water and grain[水穀之海] replenishes Jing-Qi-Shen and Blood. When connected to the Four Qi Intersections, the marrow sea is connected to 'head qi with intersection', qi sea is connected to 'chest qi with intersection', sea of water and grain or blood sea is connected to 'stomach qi with intersection', otherwise sea of water and grain is connected to 'shin qi with intersection'. Conclusions : The Four Seas are designated to the shu points due to their accumulation of Qi when the main elements of Jing-Qi-Shen and Blood are deficient or excessive, allowing for the most convenient management and manipulation of the condition of these main elements. In clinical practice, the shu points of the Four Seas will likely increase treatment efficacy for conditions that include psychological aspects.

Objective : Standard of measurement in Korean Medicine has been changed in dynasty and location. Thus, cun (寸) and chi (尺) as unit of measurement for meridians and acupoints could be recognized as the length of equally divided portions of a certain long bone or the distance between two anatomical landmarks and as an symbolical meaning to date. The goal of this study is to propose a new standard measurement in the metric system for the relative measurement of cun and chi as unit of measurement for meridians and acupoints in normal male legs. Methods : This study was conducted by gauging each parts of normal male legs in the metric system and comparing to the relative measurement of cun and chi as follows; to calculate 1 cun, the length of each parts was divided into the unit of cun referred to Measurement of the Bone in Neijing Lingshu (靈樞 骨度篇); it was compared the unit of cun referred to Measurement of the Bone in Neijing Lingshu with cun which was calculated by dividing subject's height into 75 cun, respectively. Result : There has no significant difference in length of 1 cun among each leg's areas based on a standard of subject's height. The unit of cun by the metric length in the legs was similar to the unit of cun referred to Measurement of the Bone in Neijing Lingshu based on each subject's height. Conclusion : It is suggested that an unit of cun as the measurement for meridians and acupoints in the male legs should be considered to the ranges from 2.4cm to 2.6cm.

Objective : The objective of this paper is to study the characteristics of the categorization of acupuncure points of the Lung Meridian(肺經) based on Hwangdineijingmingtang(黃帝內經明堂). Method : This paper examines several texts regarding the Lung Meridian. Result and Conclusion : Out of Yang Shangshan(楊上善)'s work, the theoretical aspects are presented in Hwangdineijingmingtang, whereas contents regarding acupuncture points are presented in Hwangdineijingmingtang. This is due to Yang's position as an imperial doctor(太醫侍御). In Hwangdineijingmingtang, Yang explains the characteristics of Metal(金) based on Hwangdineijingmingtang followed by an explanation of the acupuncture points of the Lung Meridian, which shows his emphasis on the relationship between the meridian as the main branch and the viscera. Along this medical logic, Yang must have included LU1(中府) into the Lung Meridian. This is Yang's unique point of view, distinguishing itself from other texts regarding the Lung Meridian. Apart from the means of explanation of the Lung Meridian by Yang, the verse 'made a volume for each 12 meridian' in the introduction of Hwangdineijingmingtang, discussion of the main treatable diseases of Hwangdineijingmingtang, contents on pathways of Lingshu Jingmai(靈樞 經脈), the start and end points of the meridians in Lingshu Maidu(靈樞 脈度) points to the assumption that each acupuncture point's belonging meridian known to us today was fixated by Yang.

Objectives : This study aims to grasp the principle of the Won Bang supplementation and draining method as mentioned in the 『Lingshu·Guanneng』 and the 『Suwen·Bazhengshenminlun』, which have contrasting properties. Methods : The texts in each chapter were analyzed to understand the supplementation and draining principle that matches the meanings of round[won,員] and angular[bang, 方]. Especially in the case of the chapter 「Bazhengshenminlun」, a hypothesis was drawn upon the relationship between the abstract explanation of the round[won,員] and angular[bang, 方] and the actual manipulation technique. This hypothesis was tested against other texts and annotations for further discussion. Results & Conclusions : The expressions 'bang[angular, 方]' and 'won[round,員]' refer to the same meanings in both chapters, as 'to be upright' and 'to be smooth,' respectively. The difference between the two chapters is that in the 『Lingshu·Guanneng』 the standard for Won Bang is the needler's movements, while in the 『Suwen·Bazhengshenminlun』, it is the patient's breathing. Moreover, while in the former the subjects of supplementation and draining are clearly divided into healthy qi and exterior pathogenic qi, in the latter the subject of manipulation is the deficiency and excessiveness caused by deviation of the healthy qi, thus making the subject of both supplementation and draining healthy qi. Based on these findings, we can conclude that the supplementation and draining of needling is divided into two methods; separating the healthy and pathogenic qi and manipulating the deficiency and excessiveness of healthy qi within the body.

Objectives : The goal of this paper is to research what affected diagrams of liver originated from Mingtangzangfutu while they were changed. Methods : Diagrams of liver in Traditional Chinese and Japanese medical books had been gathered as many as possible. After they were divided into ones which were originated from Mingtangzangfutu and the others, diagrams originated from Mingtangzangfutu, were again classified into 4 filiations according to Huang Longxiang(黃龍祥)'s standard. Apart from his classification, they were analysed by 4 form factors, e.g. shape, number, veins and petiole of leafs. Results : Reliability of this methods had been confirmed by the correspondence with Huang's 14 standard books, before 29 diagrams of liver were derived from 33 books including 13 books that Huang had already suggested. The lobes of liver in most of diagrams resembled 7 lanceolate or long oval leafs, or a maple leaf with 6 indentations, 4 left lobes and right 3 ones. In most of diagrams, veins of leafs were described variously, and petioles of leafs were drawn more shortly or longer. Analysing 29 diagrams by 4 form factors proved that Huang's classification had crossing features among 4 filiations. This phenomenon implied the painters or doctors drawing diagrams might not convince if the shape of liver was correct or not. Although veins and petiole of leafs in diagrams of liver could be compared with tissues in liver in modern human anatomy, diagrams were not been affected by dissection from Yuan(元) to middle Qing(淸) dynasty. Conclusions : Lingshu(靈樞), Nanjing(難經) and Wang Bing would had constantly acted on 29 diagrams of liver, since diagram of liver originated from Mingtangzangfutu, appeared first in Zhenjiujuying(鍼灸聚英). But they did not come from dissection during same periods.

In "Lingshu Benshen". five vicera are damaged due to changes in emotion having qi flow opposite to five viscera. As a result, it suggests that mental and physical illness could develop. The content of this piece can be explained in relation to five elements but uniformly through qi's flow. The contents can be summarized as follows. 1. The Heart is fire among the five elements and mainly characterized with dispersing. The flow of its qi is characterized facing upward and outward. On the other hand, being afraid or thinking seriously is characterized by making qi to go downward and stop so that the flow of qi is mainly facing toward inward and downward, damaging the heart. 2. The spleen has the conveyance function and spreads qi. On the other hand, worry and emotion inhibit qi function, blocking qi, damaging the spleen. 3. The liver has dispelling and removing functions and the power of sending up. The qi flow goes toward upward and outward. On the other hand, sadness stagnates qi, preventing the flow of liver's qi, damaging the liver. As a result, work is not done accurately. Madness develops with heat accumulated with qi stagnation. When qi is not sending up, mentality is not clear, leading to forgetfulness. 4. The lung has astringent and sending down functions, lowering qi. On the other hand, happy and joyful emotions bring up qi, showing the opposite flow of qi compared with the lung, damaging the lung. 5. The kidney has closing and storing functions, making qi flow to downward and inward. On the other hand, being angry makes qi to go up. Excessive expression of anger damages the kidney. As a result, the yin function of kidney does not work properly, leading to forgetfulness.

Background and Purpose : The concept of $Wux{\'{\i}}ng$(五行) is central to all elements of the Koran traditional medicine. And $Wux{\'{\i}}ng$ is considered to one of the constitution theories in some of oriental medicine fields in South Korea. The aim of this study is to find necessary and concrete estimation factors for distributing patterns of $Wux{\'{\i}}ngr{\'{e}}n$(五行人) respectively. Methods : We translated and summarized the records about distinguishing characteristics and distributing points of Wu-Xing Ren described in <$L{\'{\i}}ngshu$(靈樞)${\cdot}$Yin-Y${\'{a}}$ng ${\`{e}}rsh{\'{\i}}wur{\'{e}}n$(陰陽二十五人)>. Some review articles were identified through searches of KISS and KERIS databases. Results and Conclusion : Concrete distinguishing characteristics and distributing points of Wu-Xing Ren were described in <$Lingshu{\cdot}Yin-Y{\'{a}}ng\;{\`{e}}rsh{\'{\i}}wur{\'{e}}n$>. According to <$Lingshu{\cdot}Yin-Y{\'{a}}ng\;{\`{e}}rsh{\'{\i}}wur{\'{e}}n$>, the most notable characteristics and distributing points are the skin color and shape of face. but the skin color and shape of face are too ambiguous to be used as distributing criteria in a practical manner. In stead size of head, longitudinal length of back, disposition, and width between both shoulders may be used as distributing criteria in practical clinic fields.

A stage-structured predator-prey system with time delay and Beddington-DeAngelis functional response is considered. By analyzing the corresponding characteristic equation, the local stability of a positive equilibrium is investigated. The existence of Hopf bifurcations is established. Formulae are derived to determine the direction of bifurcations and the stability of bifurcating periodic solutions by using the normal form theory and center manifold theorem. Numerical simulations are carried out to illustrate the theoretical results.

This paper presents a novel algorithm for nighttime detection of the lane markers painted on a road at night. First of all, the proposed algorithm uses neighborhood average filtering, 8-directional Sobel operator and thresholding segmentation based on OTSU's to handle raw lane images taken from a digital CCD camera. Secondly, combining intensity map and gradient map, we analyze the distribution features of pixels on boundaries of lanes in the nighttime and construct 4 feature sets for these points, which are helpful to supply with sufficient data related to lane boundaries to detect lane markers much more robustly. Then, the searching method in multiple directions- horizontal, vertical and diagonal directions, is conducted to eliminate the noise points on lane boundaries. Adapted Hough transformation is utilized to obtain the feature parameters related to the lane edge. The proposed algorithm can not only significantly improve detection performance for the lane marker, but it requires less computational power. Finally, the algorithm is proved to be reliable and robust in lane detection in a nighttime scenario.
