Objective: The purpose of this study is to discourse upon that the construction of Sasang Constitutional Medicine has a significant property of Oriental Medicine by explaining the disparity of the viscera and bowels of four constitutions through the special quality of ying-qi and wei-qi circulating in human body on the basis of the channel-qi theory of ${\ulcorner}Huangdi$ $Neijing{\lrcorner}$ Conclusion: 1. Primordial-qi is the congenital essence inherited from the parents and pectoral-qi, ying-qi and wei-qi is the acquired essence derived from the food and air that human eat and breathe. 2. Ying-qi and wei-qi circulates in the meridian system by the strength and pushing of pectoral-qi under the influence of primordial-qi 3. Ying-qi, by the pushing function of pectoral-qi, determines large lung-small liver and small lung-large liver according to the innate quantity of qi and blood. 4. Wei-qi, by the pushing function of pectoral-qi, determines large spleen-small kidney and small spleen-large kidney according to the innate quantity of qi and blood. 5. The heart in the theory of the meridian system's fetus-nourishing and Sasang Constitutional Medicine is involved in the formation of viscera and bowels as governing human body and seven emotions. 6. It is considered that Taiyang person and Taiyin person have the constitution influenced by ying-qi. 7. It is considered that Shaoyang person and Shaoyin person have the constitution influenced by wei-qi. The inquiry into several literatures on the basis of the channel-qi theory of ${\ulcorner}Huangdi$ $Neijing{\lrcorner}$ leads us to the idea that the construction of Sasang Constitotional Medicine is another well-implied representation of the property of the meridian doctrine in the existing Oriental Medicine. And it is considered that the more continual studies of literatures and Sasang Constitutional Medicine Acupuncture are necessary henceforth.

Yin Yang theory is the first and the last one to interpret diseases apply to treatment in oriental medicine. So it is regarded as the way of heaven and earth, the discipline of all things, the origin of change, the beginning of giving birth and death, the source of spirit. These regulatory passages are needed to compare with western medical physiology and analyzed whether it has scientific bases or not. The Yin Yang theory of traditional oriental medicine are summerized from the descriptions of Scripture of Documents, Ying Wei theory of Huangdi Neijing. Meanwhile up-to-date neurobiological and molecular genetic theories on circadian physiology are reviewed in western medicine. Sunshine is transferred through RGC to SCN, herein the central circadian rhythm is made by zeitgeber and interaction of melatonin secreted from pineal body and orexin from mp pan of hypothalamus. So HPA axis is activated and controlled under the circadian rhythm and affects peripheral tissues and cells of whole body through glucocorticoid hormones. First of all, the circadian rhythm makes the basic patterns of human life in biological and sociological meaning. It is almost same context with the record of the Scripture of Documents. Also the Ying Qi and Wei Qi is basically same with the sleep-awake mechanism, that is melatonin/orexin signal or per/clk/bmal/cry genes with circadian activation and activity of each organ's physiological function. Conclusively it can be said that Yin Yang is a priori principle of living things and the beginning of giving birth and death for activation of them biologically, as is described in Huangdi Neijing.

Objective : To study of Literature on the Ying Qi and Wei Qi One of thing that is among basis theory of Oriental medicine is Vital Essence, Vitality, Qi and Blood(精神氣血) justly. Results : Physiological special quality of Ying Qi(營氣) first, flows within Blood Circulation and the temper is mild and second, transform blood and grow up whole body, and follow through Pectoral Qi(宗氣). Wei Qi(衛氣) means running regeneration of material that do guard action of human body as refined nutritious substances transformed in food. Physiological special quality of Wei Qi(衛氣) first, nature is fast, smooth, and sharp. And it flows outside Blood Circulation. Second, go on muscslar gap without following through Pectoral Qi(宗氣). Ying blood(營血) flows within Blood Circulation means living body ingredient which thing reveals by circulation of the blood change phenomenon. Ying Qi(營氣) is Ying(營) in meaning which go on meridians, therefore meridians as wandering living body reaction route mean. This Ying Qi(營氣)'s physiology transform blood and grows up whole body and flows within Blood Circulation. It becomes most important ingredient of composition of blood, Wei Qi(衛氣) transforms and becomes nutrition constantly by running regeneration of material which transform in Jungcho(中焦) and spread by spreading action of upper chest exhaust in lower belly above the blader of apriority, Kidney-yang.

Fiber Bragg grating (FBG) sensors already have been the focus for structural health monitoring (SHM) due to their distinguishing advantages. However, as bare optical fiber is very fragile, bare FBG strain sensor without encapsulation can not properly be applied in practical infrastructures. Therefore encapsulation techniques for making encapsulated FBG strain sensor show very important in pushing forward the application of FBG strain sensors in SHM. In this paper, a simplified approximate method to analyze the stress transferring rules for embedded FBG strain sensors in concrete monitoring is put forward according to mechanics of composite materials. Shear lag theory is applied to analyze the stress transferring rule of embedded FBG strain sensor in measured host material at the first time. The measured host objects (concrete) and the encapsulated FBG strain sensor are regarded as a composite, and then the stress transfer formula and stress transfer coefficient of encapsulated FBG strain sensor are obtained.

Objectives : Through the analysis of the harmonization(和) thought in Traditional Chinese culture, and then excavate the theory and application of Harmonization Method(和法) in Huang Di Nei Jing(黃帝內經) and Shanghan Zabing Lun(傷寒雜病論). Methods : We find the harmonization(和) means harmony and neutral in traditional Chinese culture, including the harmony of society, the harmony of the mind and the body, and so on. Results : Huang Di Nei Jing(黃帝內經) emphasized the health status is moderate, the disease state is unbalance, preserving our health should keep the yin-yang equilibrium, treating disease should reestablish the equilibrium status, which establish the foundation of the theory of Harmonization Method(和法). Shanghan Zabing Lun(傷寒雜病論) created the methods of settlement and harmony, which is a precedent for the wide application of Harmonization Method(和法) for future generations, including to reconcile the interior-exterior and yin-yang, to harmony the ying-wei and qi-blood, to reconcile the activities of qi of internal organs. Conclusions : The harmonization(和) is the ideological foundation of the theory system of TCM and the Harmonization Method(和法). The Harmonization Method(和法) is an important treatment method for clinical practice of Traditional Chinese Medicine.

The whirl and generated forces of rotating cylinders with different diameters placed in still water and in flow are studied experimentally. For the rotating cylinders in still water, the Same Frequency Whirl (SFW) and Different Frequency Whirl (DFW) have been identified and illustrated. The corresponding SFW and DFW areas are divided. The Root Mean Square (RMS) values of the generated force coefficient dramatically increase in the defined ranges of Resonance I and Resonance II. For the rotating cylinders in flow, the hydrodynamics, SFW and DFW are illustrated. The hydrodynamic, SFW and DFW areas are divided. The RMS values of the generated forces in the range of Resonance II are much smaller than those in still water due to the generated lift forces. The discussion suggests that the frequency of the DFW may equal multiple times or one-multiple times that of the rotating frequency: the whirl direction of the DFW with multiple times the frequency of the rotating frequency is the same as the rotating direction. The whirl direction of the DFW with one-multiple times frequency of the rotating frequency is opposite to the rotating direction.

An innovative partially precast partially encased composite beam (PPECB) is put forward based on the existing research. In order to study the flexural performance of the new composite beam which has precast part and cast-in-place part, six prefabricated specimens and one cast-in-place specimen are designed with considering the influence of the production method, the steel flange thickness, the concrete strength grade and the stirrup process on the behavior of the composite beam. Through four points loading and test data collection and analysis, the behavior of partially prefabricated specimen is similar to that of cast-in-place specimen, and the casting method, the thickness of the steel flange, the concrete strength grade and the stirrup process have different influence on the crack, yield and peak load bearing capacity of the component. Finally, the calculation theory of plastic bending of partially precast partially encased concrete composite beams is given. The calculation results are in good agreement with the experimental results, which can be used for practical engineering theory guidance. This paper can provide reference value for further research and engineering application.

The present writer studied the medical thought of 'You-Yi(尤怡)', the medical expert of the early 'Qing(淸)' Dynasty, which can be summarized as following. 1. 'You-Yi' writed many essays and treaties about 'Shang-Han-Lun(傷寒論)' and 'Jin-Gui-Yao-Lue(金?要略)', both of which are the writings of 'Zhang-Zhong-Jing(張仲景)', the medical saint of 'Han(漢)' Dynasty, and those writings include 'Shang-Han-Guan-Zhu-Ji(傷寒貫珠集)', 'Jin-Gui-Yao-Lue-Xin-Dian(金?要略心典)', 'Yi-Xue-Dou-Shu-Ji(醫學讀書記)', 'Jin-Gui-Yi(金?翼)', and 'Jing-Xiang-Lou-Yi-An(靜香樓醫案)'. 2. A theory of 'Tai-Yang(太陽)' syndrome, including 'San-Gang-Ding-Li(三綱鼎立)', was proposed by 'Fang-You-Zhi'(方有執)' and 'Yu-Chang(喩昌)' and it came to be one of the leading theory of the 'Shang-Han-Lun', 'You-Yi' rejected their opinions in which they insisted that the 'Feng(風)' hurts the 'Wei'(衛)' and the 'Han(寒)' hurts the 'Ying(營)', and he advocated his particular idea that the 'Xie-Qi'(邪氣)' can directly hit skin, flesh, 'Ying-Wei(營衛)', the Five Organs and the Six Viscera(五臟六腑), regardless of 'Zhong-Feng(中風)' or 'Shang-Han(傷寒)', and he insisted that there is need to be anxious about Whether the 'Ying-Wei' is strong or weak. 3. In 'Shang-Han-Guan-Zhu-Ji', 'You-Yi' invented the eight classifications in treating the 'Shang-Han' and he did not follow the old theories hitherto. He divided the book into six parts via the clinical experiences, and the Classification and Logics in Treatment(辨證論治), and he put several titles on 'Jin-Gui-Yao-Lue. And he newly edited the original text of 'Shang-Han-Lun' and arranged 'Zhong-Jing(仲景)'s Six Meridian(六經) categories. Each syndrome in 'Tai-Yang' 'Yang-Ming(陽明)', 'Shao-Yang(少陽)', 'Tai-Yin'(太陰)', 'Shao-Yin(少陰)' and 'Jue-Yin(厥陰)' has its own categories in treatment. 4. In explaining the Six Meridian(六經) and the Organs and Viscera(臟腑), 'You-Yi' legislated the syndrome in 'Three Yang(三陽)' into Meridian(經) and Viscera(腑) ; the syndrome in 'Three Yin(三陰)'into Meridian(經) and Organs(腑). He also concluded that 'Shang-Han-Lun' not only discussed 'Wai-Gan(外感)' but also included the Internal Hurt(內傷) and Miscellaneous Diseases(雜病). 5. In his academic research, 'You-Yi' followed 'Zhong-Jing' in classifications and prescriptions and succeeded the theory of 'Ma-Chu(마숙)' and 'Li-Zhong-Zi(李中梓)', but was not tied to any stereotyped former practices. He put emphasis on the Spleen(脾) and the Kidney(腎) as he harmonized the Middle Energizer(中焦焦) with the taste of 'Gan(甘)' and 'Wen(溫)' and enjoyed strengthening 'Yang' by benefitting the 'Qi(氣)'. 6. He discussed in detail the causes, mechanism and symptoms on 'Tan-Yin(痰飮)' and proposed the seven categorizes in treatment. 7. He sorted the causes of 'Zhong-Feng' into two kinds of the 'Feng' via 'Wai-Gan' and Internal Hurt, and recognized these two 'Feng's correlate as mutual sources of diseases. He insisted that the origin of the 'Feng' exists in the 'Liver(肝). He also established the eight categories in treating the 'Feng'. 8. 'You-Yi' belong to the classifications and Logical Treatment School. And he, considering he respected and followed 'Zhong-Jing' and 'Li-Zhong-Zi', belongs to the successor to the 'Wen-Bu(溫補)' School. 9. His writings, especially the 'Shang-Han-Guan-Zhu-Ji' and the 'Jin-Gui-Yao-Lue-Xin-Dian', are excellent commentary works on the originals, so they served as significant guide books for many junior scholars. For penetrating the 'Shang-Han-Lun' with his unique way of classification of treatment, he has been highly appreciated by later generations including scholars like 'Tang-Li-San(唐立三)' in the 'Qing' Dynasty, and so many more ones thenceforth. In conclusion, on the base of this study, it is hopefully proposed that the still more profound research on the medical thought of 'You-Yi', as one of the most distinguished scholars, an expert clinician and an earnest writer as well.

Objectives : To review the meaning of Open-Close-Pivot and its transition over time. Methods : Annotations and explanations in chapters where the theory of Open-Close-Pivot originated from in the "Suwen(素問)" and "Lingshu(靈樞)" were examined, followed by philological examination of key physicians. Results & Conclusions : Yang Shang Shan(楊上善) compared the 'Open-Close-Pivot' to a door. Wang Bing(王冰) explained it's movement and stillness to be the principle behind the Three-Yin-Three-Yang's threefold division. Wang Ji(汪機), in "XuSuwenChao(續素問鈔)" explained its physiological function as the entering and exiting of Ying Wei(營衛), and its scope to be exterior, interior, and center. Ma Shi(馬蒔) stratified it similar to "Shanghanlun(傷寒論)"'s six stages, while Wu Kun(吳崑) categorized Shaoyang(少陽) as being in-between exterior and interior. Zhang Jing Yue(張景岳) suggested a standard for the entering-exiting and exterior-interior-center concepts of the Open-Close-Pivot. Zhang Zhi Cong(張志聰) argued a theory of Open-Close-Pivot that emphasized the meaning of Three-Yin-Three-Yang, while Gao Shi Zong(高士宗) explained the relationship between Open, Close, Pivot and the functioning process. Shi Shou Tang(石壽棠) explained the physiology and pathology in the actions among Open-Close-Pivot with a focus on Pivot. Ke Qin(柯琴) applied Open-Close-Pivot to "Shanghanlun(傷寒論)" and used it as the basic principle to the Six Channel Ground Theory(六經地面說), also clinically applying it in the identification and treatment of the Six Channel patterns. Conclusions : Counting based word embedding methods seems to be more effective than.
