Mankind spends a third of it's lifetime sleeping. Sleep deficiency can cause several psychological and physical complications - as well as death - if prolonged over extended periods. Therefore, sleep is a substantial part of life and essential to the preservation of human-life. In modern society, human-beings are having more difficulty with sleep than ever before. Consequently, the need for medical research on sleep has increased as well. There are no studies in current western medicine that focuses entirely on sleep alone. However, there have been ongoing research by traditional eastern medicine on sleep and sleep-related-dysfunctions since ancient times which has yielded diverse results. Undertaken a study of the sleep and sleep-related-dysfunction in traditional medicine of East-asia, I have summarized my studies into the following. 1. From ancient china to the age of the warring state(戰國時代) - ground on few data that we can get - humans have a simple and rough cognizance of sleep and sleep-related- dysfunction. But people are little removed from shamanism yet. 2. After Han(漢) dynasty, in "Huang Di Nei Jing(黃帝內經)" and "Shang Han Lun(傷寒論)" and "Jin Gui Yao Lue(金匱要略)", people present a basic physiology and pathology of sleep. 3. The theory has improved repeatedly in quality and quantity through "Zhen Jiu Jia Yi Jing(針灸甲乙經)" of Huang Fu Mi(皇甫謐) of Jin(晉) dynasty, "Bei Ji Qian Jin Yao Fang(備急千金要方)" of Sun Si Miao(孫思邈) of Tang(唐) dynasty to "Tai Ping Sheng Hui Fang(太平聖惠方)" of Song(宋) dynasty.

Analysis of the species of wood in the wooden materials and the chemical composition of the fabric of the clothing excavated from the tomb of Yi Jing (1580-1642) has determined that the wooden materials, including the coffin (內棺, naegwan), burial chamber(外棺, oegwan), chilseongpan(七星板, bottom-lining board), and fan-shaped slats were made of pine(Pinus densiflora). The analysis of the fabrics suggested that the cloth attached to the fan-shaped slats, the funeral banner with inscriptions, and the five pouches for the corpse (五囊, onang) were all made of silk. The jacket was made of plain-weave cotton, while the inner and outer cloth of the socks were made of cotton and hemp, respectively. Among the silk items, the pouches for the left and right feet (constituting the five pouches for the corpse) were made from a satin-weave figured silk, while the other silk items were made of ju(紬), or plain-weave silk fabric. Infrared analysis revealed that the fan-shaped slats were decorated with cloud patterns across the entire surface, while the funeral banner and the five pouches for the corpse bore ink inscriptions.

This paper is sequel to the paper titled 'A study on research methodology of the quoted verses in Dong-uisusebowon(2)'. In the previous study, Tao-ren-cheng-qi-tang(桃仁承氣湯) and Di-dang-tang (抵當湯) lines from Shanghanlun quoted in the Dong-uisusebowon were examined. Through this study, we learned that Heo, Jun corrected these texts in the Dong-uibogam to avoid logical contradiction, which were again quoted by Yi, Jema in the Dong-uisusebowon. Thus the quotations in Yi's book were also corrected of the contradictory lines as found in the source text, Shanghanlun. In this paper, I would like to examine the lines regarding Jeokseokji-uyeoryang-tang(赤石脂禹餘糧湯) and Gan-cao-xie-xin-tang(甘草瀉心湯). Firstly, in the case of Jeokseokji-uyeoryang-tang(赤石脂禹餘糧湯) lines, many changes in contents were made to resolve contradiction within the lines as previous cases. By quoting the Dong-uibogam directly, Yi, Jema inherited the thoughts of Heo, Jun in his work. Secondly, in the case of Gan-cao-xie-xin-tang(甘草瀉心湯) lines, Heo, Jun suggested new perspectives on Pi(痞, stuffiness) and Jie-xiong(結胸, chest bind) different to those of Zhang Zhong Jing, based on empirical knowledge of later days. Yi, Jema quoted these corrected lines, which implies Yi's agreement to the theories of Heo. However, Yi made clear his difference in perspective with Heo through his unique theory of the Four(Sasang) Constitutions. I conclude my research regarding quotations in the Dong-uisusebowon by stressing the necessity of research on the Dong-uibogam prior to any further research regarding quotations in the Dong-uisusebowon.

This study makes clear Huang Yuan-Yu(黃元御)'s medical thoughts Yi-philosophically. Yi-philosophy(易學) since ancient times is occupied by fundamental problems of various fields of Oriental Science. Confusian Medicine Reseachers of Zhang Jie-Bin(張介賓), Zhang Nan(章楠), Zhu Zhen-Heng(朱震亨) was seriously affected by Yi-philosophy(易學) and Confucianism(儒學). But I don't think that the majority of their medicine theories are occupied by Yi-philosophy(易學) and Confucianism(儒學). But Huang Yuan-Yu(黃元御) studied medicine thoughts on the basis of Tu Shu Yi(圖書易) in almost whole medicine theories and clinical contents. Therefore this study researched medical thinkings of Huang Yuan-Yu(黃元御) on Yi-philosophical medical viewpoint Tu Shu Yi(圖書易)-scientifically. Especially in this paper the author examined a characteristic point in medical thoughts of Huang Yuan-Yu(黃元御), the difference of existing medicine on Nei-Jing(內經) and Yi-medicine of Huang Yuan-Yu(黃元御), a commonness of medicine principles of Huang Yuan-Yu(黃元御) and Li Ji-Ma(李濟馬)), medicine theories of Huang Yuan-Yu(黃元御) on Tu Shu Yi(圖書易) and a background of Yi-philosophical medical standpoint. The results was summarized as follows; First, Huang Yuan-Yu(黃元御)'s standpoint on five phase is that the relation of earth and wood fire metal water is form and use(體用). Huang Yuan-Yu(黃元御) insists that the earth represents existence itself and wood fire metal water is concepts that represents actual states. Second, the concept of Four-Constitution of Huang Yuan-Yu(黃元御) and Li Ji-Ma(李濟馬) is same. Third, Huang Yuan-Yu(黃元御) doesn't have a standpoint of five-phase on Nei-Ching Medicine, but a standpoint of five-phase on Yi-philosophy. Fourth, water, fire, metal, wood is Four-Constitution that middle qi transformed. Fifth, the middle qi is yang-earth and yin-earth of the spleen and stomach, the physiological function of four viscera is maintained by the movement of ascending and descending of yin and yang earth. Sixth, The middle qi is main role of Four-Constitution. Exchanging of water and fire and the movement of ascending and descending of metal and wood depends on the earth. Seventh, generally medicine researchers speak that human mind is a main role of psycho-function of heart, but Huang Yuan-Yu has the standpoint of spleen-stomach oriented seven emotions not human-mind oriented viewpoint. It represents that a existing thinking of heart-earth center is changed to medical viewpoint of spleen-earth center. Eighth, There is enough ground for controversy on where is the middle point of human in five viscera. Is that spleen or heart? Huang Yuan-Yu(黃元御) insists that the spleen and stomach is middle point, but the standpoint in Four-Constitution medicine of Li Ji-Ma(李濟馬) is that middle point is heart.

Mankind has had various medical treatments and theories as the result of steady researches about many diseases. Medical science has something to do with religions closely. That is, he tries to solve the problem connected with his life through medicine, while he tries to overcome the fear of death through the religion. Also I have tried to establish the relations between Oriental medicine. This research shows that the relation between Taoism and medical morals(醫德). The results of this research are following. The moral consciousness in medicine is the one of great traditions in Oriental medicine which comes to the front by Sun-Si-Miao(孫思邈). That is influenced by the ethical view that a moral act influences the long and the short of life. ${\ulcorner}$Tai-Ping-Jing(太平經)${\lrcorner}$ says that man enjoys longevity if he tends his parents with filial piety and then is aware of the principle of heaven and earth. Sun-Si-Miao teaches in Da-Yi-Jing-Cheng(大醫精誠) that 'Treat the patient impartially', 'Don't weigh the merits when treating the patient', 'Avoid the use of animal medicines as you can.', 'As a man sows, so he shall reap.', Don't be jealous and don't be proud.', which are closely related to main principles about act and taboo suggested in ${\ulcorner}$Bao-Piao-Zi(抱朴子)${\lrcorner}$

This paper presents a moth-flame optimization (MFO)-based maximum power point tracking (MPPT) method for photovoltaic (PV) systems. The MFO algorithm is a new optimization method that exhibits satisfactory performance in terms of exploration, exploitation, local optima avoidance, and convergence. Therefore, the MFO algorithm is quite suitable for solving multiple peaks of PV systems under partial shading conditions (PSCs). The proposed MFO-MPPT is compared with four MPPT algorithms, namely the perturb and observe (P&O)-MPPT, incremental conductance (INC)-MPPT, particle swarm optimization (PSO)-MPPT and whale optimization algorithm (WOA)-MPPT. Simulation and experiment results demonstrate that the proposed algorithm can extract the global maximum power point (MPP) with greater tracking speed and accuracy under various conditions.

This paper presents an investigation on the free vibration characteristics of functionally graded nanocomposite double-beams reinforced by single-walled carbon nanotubes (SWCNTs). The double-beams coupled by an interlayer spring, resting on the elastic foundation with a linear layer and shear layer, and is simply supported in thermal environments. The SWCNTs gradient distributed in the thickness direction of the beam forms different reinforcement patterns. The materials properties of the functionally graded carbon nanotube-reinforced composites (FG-CNTRC) are estimated by rule of mixture. The first order shear deformation theory and Euler-Lagrange variational principle are employed to derive the motion equations incorporating the thermal effects. The vibration characteristics under several patterns of reinforcement are presented and discussed. We conducted a series of studies aimed at revealing the effects of the spring stiffness, environment temperature, thickness ratios and carbon nanotube volume fraction on the nature frequency.

East-Asian intellectual societies in the pre-modem age sustained a holistic system of poem-calligraphy-painting trinity until the coming of Western modernism. Therefore, it has been insisted that the principles of traditional landscape gardening were greatly influenced by those of landscape painting and related literature. This study examined those influences closely to discover the essence of traditional Asian landscape architecture through a comparative study between Chinese landscape painting theory and landscape gardening theory within the dual categories of 'contents(value and meaning)' and 'form(view and spatial structure)'. The most important theme of landscape painting theory in contents category was 'Chi and its Vitality(氣韻生動)'. The matching theme in landscape design field was 'Feng-Shui(風水)' and 'Yi-Jin'g(意境)'. The most important theme of landscape painting theory in formal category was 'the Three Ru1es of Perspective(三遠法)'. And the matching theme of landscape design theory was 'Yindi(因地)' and 'Jie-Jing(借景)'. The most important theme of landscape painting theory in formal category was 'the Three Rules of Perspective(三遠法)'. And the matching theme of landscape design theory was 'Yindi(因地)' and 'Jie-Jing(借景)'. It was found that themes and various principles of both fields were closely inter-related and have much in common in their representation of contents and form. In the close relationship with main art genres like this, the landscape gardening could have been recognized as one of the genres of fine art.

This study analyzes a medicine and iching-study(易學) and vital meaning through a me야cal science ruler called ZhangNan(章楠) of Qing-Dynasty(淸代), but has a purpose. First of all, the writer judges that the ZhangNan's medicine did not get out of a tradition of a Rui-Yi(儒醫, Confucian medicine) medicine greatly. He considered philosophy character of Rui-Yi formed after Jin-Yuan Dynsty(金元代) a purpose of own medicine. A way he kept the human life in order to realize a large meaning of Confucianism, and to stop a disease was necessary and spoke necessity of a medicine for this. Though a medicine is small, but becomes necessary thing in order to realize Confucianism whether a medicine and Confucianism are the only each other. The ZhangNan presented Zhi-zhong-he(致中和) with a way as soon as it is a purpose of a medicine, but ZhangNan is opening the point that Xing(性) was given 'Taiji(太極)'to. If Neo-Confucianism named 'Taiji(太極)-xing(性)-li(理)' is general, but ZhangNan is introducing the Taiji with Chi(氣). ZhangNan introduces the Taiji(太極) with one Chi(氣) and is rea야ng thing with another Zhu-zai(主宰) except Taiji, but cannot but recognize this with one in characteristics of a medicine ruler. A disregard is the inferior results, and this can do entrance of the Huang-di-nei-jing(業帝內經) which put a base with Han-Dynasty(漢代) iching-study(易學) and this too. It is made concrete 'Zangfu(藏府)-Taiji', and he is considering 'Dan-tian(丹田)-Taiji‘ in a discussion about the Great Absolute to be physical too more. Also, Taiji' is describing a point of contact that a spirit and the body meet with.
