Objectives : This study aims to examine the exterior relief method through pungent-cool properties in comparison to pungent-warm properties historically, to understand the meaning of 'exterior relief through pungent-cool' more thoroughly. Methods : Contents mentioning the treatment method directly were examined historically, then analyzed. Results & Conclusions : The method to relieve the exterior through pungent-cool properties has developed by overcoming the limitations of the method to relieve the exterior through pungent-warm properties since it was first established in 『Shanghanzabinglun』(『傷寒雜病論』). The term 'relief of the exterior through pungent-coolness'(辛凉解表) was first mentioned in the Ming period, referring to weak level of perspiration. Yetianshi(葉天士) explained it as communicating Weiqi(衛氣) using pungent-cool medicinals for heat to discharge through the exterior, resulting in mild sweating. In 『Wenbingtiaobian』(『溫病條辨』) the term 'to relieve the flesh'(解肌) refers to both mild sweating through pungent-warm medicinals and the opening of the exterior through pungent-cool medicinals for pathogenic qi to exit, resulting in sweating. If the exterior relief of the pungent-warm medicinals happens through the warm Yang qi(陽氣) stimulated the inner Yin fluids(陰液) to discharge as sweat, that through pungent-cool medicinals relieves stagnation in the exterior, opening up a way for the pathogenic heat to exit. From the perspective of the main therapeutic mechanism for pungent-cool medicinals to be its coolness relieving heat, the term 'exterior relief through pungent-coolness' becomes erroneous. For the 'exterior relief through pungent-coolness' category to be valid, the meaning of 'exterior relief' needs to be expanded to include not only stimulated sweating but the treatment process that could result in sweating.

The cooling mechanism for a liquid rocket engine of 10tf-thrust using kerosene as a fuel was studied from the viewpoint of both the regenerative and curtain cooling. Based on the concept of a highly-stratified gas flow in the combustion chamber, the cross section of the combustion chamber was spilt into 2 independent parts, core and exterior part. Additional fuel is injected into the exterior section and gas temperature can be reduced in the exterior section. Consequently, the heat flux into the coolant and wall temperature are reduced and the thermal stability of a liquid rocket en g i.ne could be improved.

Objectives : The first object is to reveal the mechanism of diarrhea based on exterior heat syndrome for Taeumin as explained in Donguisusebowon's Taeeumingansuyeoliyeolbyeonglon. The second objective is to review the treatment for Taeumin as explained in Leejema's Galgeunnabogjatang because the drug composition of Galgeunnabogjatang, the drug that treats this syndrome, is not written. Methods : As the first step, the paper will review the disease pathology for Taeumin written, and check the existence of disease path that can be viewed as exterior heat syndrome. As the second step, the paper will review the probability of exterior heat syndrome deriving from Taeumin disease path and morph into the exterior heat syndrome. Results : Using the first step to discover the direct correlation between exterior heat syndrome and the theory of disease for Taeumin led to a failure, but through the second step, the paper was able to confirm the probability that exterior heat syndrome could derive from Wiwansuhanpyohanbyeong's Wiwanhanjeung. Based on this, the paper was able to determine the Galgeunnabogjatang suitable for the treatment of exterior heat syndrome. Conclusions : Exterior heat syndrome is created when healthy qi is stimulated to quickly build up the pathogen of Taeumin exterior heat syndrome, but only exterior heat is generated and the cold remains. Its main symptoms are fever, excessive sweating, and difficult painful red-urination. Exterior heat syndrome diarrhea refers to the diarrhea which is generated from the Taeumin's disease pathology. The paper determined that Galgeunnabogjatang, which is listed in Donguisusebowon the seventh edition Boyubang.

The purpose of this article was to compare 'The Discourse on the Constitutional Symptoms and Disease' of ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ written in 1894(Old Edition(舊本)) with that of ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901(In Edition(印本)), and to find the idea of pathologic mechanism and classification of 'the Exterior and Interior disease'. the conclusions were as follows. 1. The classification of constitutional symptoms and disease of Soeumin and Soyangin in 'Old Edition(舊本)' was almost equal to that in 'In Edition(印本)' 2. In pathological mechanism of constitutional symptoms and disease of Soeumin and Soyangin, 'The Exterior Disease' could be explained as the disease resulted from fight between 'Yang-chi(陽氣)(Hot-chi(熱氣))'of 'Thoracic vertebrae' and 'Yin-chi(陰氣)(Cold-chi(寒氣))' of 'Bladder' and 'The Interior Disease' between 'Hot-chi(熱氣)(Stomach-chi(胄氣))' of 'Stomach' and 'Cold-chi(寒氣)' of 'Large intestine'. 3. 'The Exterior Symptoms and Disease of the Exterior and the Interior Disease(表裏之表病)' could be explained as the disease occurring at the Branch portion(large portion)(標) by overcoming of Pathogenic factors but Vital energy still sufficient, and 'The Interior Symptoms and Disease of the Exterior and the Interior Disease(表裏之裏病)' occurring at Root portion(small portion)(裏) by invasion of Pathogenic factors and Vital energy almost exhausted. 4. In the classification of constitutional symptoms and disease of Taeumin, 'The Exterior Symptoms and Disease of the Exterior and the Interior Disease(表裏之表病)' in 'Old Edition(舊本)' were rearranged to 'The Exterior Disease' in 'In Edition(印本)', 'The Interior Symptoms and Disease of the Exterior and the Interior Disease(表裏之裏病)' to 'The Interior Disease'. 5. It was assumed that 'The Exterior and the Interior Disease' of Taeumin could be explained in relation between the exterior and e interior, based on the Healthy energy(保命之主) and e concept of the Branch and the Root portion

As a newly structural system, RCS composite system has been researched last two decades. However mechanism of exterior T-type joint for RCS composite system is not well known. This research is focus on the exterior T-type joint for RCS composite system. Specimens are designed by the ASCE guideline, tested and compared with the inner RCS joint. Test variables include face bearing plate(FBP), extended face bearing plate(E-FBP) and U-bar. The tests indicate that the strength of exterior T-type joint is higher than that of the guideline by ASCE. The U-bar has a significant effect on the joint strength and absorbing the strain energy.

1. Objectives This paper is written for clear understanding on the concepts of 'Deep adherence of the Nature' and 'Sudden explosion of the Emotion' and for intensive comprehension of Mechanism of 'The Exterior Disease' and 'The Interior Disease' by The Nature and the Emotion. 2. Methods The study mainly based on "The exterior disease injured by the Nature, the interior disease injured by the Emotion" and deals with 'Seongmyungron, Sadanron, Hwarkchungron and Jangburon'. 3. Results and conclusions The conclusions as follows (1) Exterior Disease in each constitution breaks out by deep adherence of the Nature. Interior Disease brings out with sudden explosion of the Emotion. (2) 'Deep adherence of the Nature' is the state that the Ear, Eye, Nose, Mouth taking care of environmental frames can't work enoughly because of wrong minds on the Jaw, Breast, Umbilicus, Abdment. 'Sudden explosion of the Emotion' is the state that the Lung, Spleen, Liver, Kidney doing human affairs doesn't do appropriately for each constitution due to negative minds on the Head, Shoulder, Waist, Hip. (3) The result that the Ear, Eye, Nose, Mouth doesn't extract the clear energy from 'Jin, Go, You, Yaek sea' so they are lack of 'Shin, Qi, Hyul, Jeong' causes exterior disease in each constitution. (4) In each constitution, Interior disease results from that the Lung, Spleen, Liver, Kidney fails to bring on the clear juice from 'Lee, Mak, Hyul, Jeong sea', so shortage of 'Jin, go, You, Yaek' results in it.

Objectives : The aim of this paper is to examine the mechanisms of spontaneous sweating and night sweating, their relationship and how the explanations of their mechanisms have changed over the course of time, through examination of past discussions on spontaneous sweating and night sweating. Methods : Contents in classical medical texts that mention the mechanisms of spontaneous sweating and night sweating among search results from databases such as the Siku Quanshu were analyzed, followed by examination of each of their mechanisms, and their relationship with each other. Results & Conclusions : The cause of night sweating before the 『Danxixinfa』 was seen to be caused by yang deficiency in relation to problems of Exterior Qi and the theory of 'Heart governs perspiration', as the focus was on the phenomenon of sweating. However, it seems that yin deficiency came to be seen as playing a more fundamental role in the process of determining the root cause of night sweating. Moreover, Zhu Danxi's emphasis on nurturing yin, the composition of Dangguiliuhuangtang, and the development of the fire-heat pathology since the Jin Yuan period added to this shift in perspective. Night sweating from Shanghan could be seen as a sign of the already damaged Exterior Qi becoming more deficient while the pathogenic qi is in the half-exterior-half-interior zone, or as the pathogenic qi which entered with the Exterior Qi unsettling yin, or as a result of heat that is produced in the struggle between healthy qi and pathogenic qi that happens when Exterior Qi enters. Night sweating from miscellaneous disease could be seen as a sign of a deficient exterior that resulted from excessive entering of the Exterior Qi during yin deficiency, or resulting from relatively excessive Exterior Qi to deficient yin, producing heat that leads to sweating. If yin is not cultivated during the night but rather consumed leading to deficiency of Exterior Qi which also needs to be cultivated during night time, it could result in sweating.

A multihomed enterprise or AS(Autonomous System) improves reliability and performance by acquiring its Internet connectivity from more than two ISP(Internet Service Provider). Multihoming protocol must allow a multihomed site whose connectivity through one of the ISPs fails to keep its Internet connectivity As one of mechanisms to do this, tunneling mechanism through Non-direct EBGP(Exterior Border Gateway Protocol) is defined. This mechanism makes connectivity to the Internet more reliable, but causes the problem that makes the communication route non-optimal. In this paper, we propose the route optimization mechanism using an extension header in the IPv6 multihoming environment.

The purpose of this research was focused on substantiating an effects of tendon-layouts and compressed stress($=f_{pc}$) induced by post-tensioning on seismic performance of post-tensioned flat plate slab-column connection designed as non-participating system. To accomplish this purpose, an experimental research of flat plate exterior slab-column connections subjected to gravity load and reversed lateral displacement history are presented. As a result, tendon-layout is a main variable to influence failure mechanism, dissipated energy and lateral deformation capacity. Furthermore, compressed stress ($=f_{pc}$) induced by post-tensioning enhanced the seismic performance of flat plate slab.

Due to functional requirements, SRC column-RC beam abnormal joints with characteristics of strong beam weak column, variable column section, unequal beam height and staggered height exist in the Steel reinforced concrete (SRC) frame-bent main building structure of thermal power plant (TPP). This paper presents the experimental results of these abnormal joints through cyclic loading tests on five specimens with scaling factor of 1/5. The staggered height and whether adding H-shaped steel in beam or not were changing parameters of specimens. The failure patterns, bearing capacity, energy dissipation and ductile performance were analyzed. In addition, the stress mechanism of the abnormal joint was discussed based on the diagonal strut model. The research results showed that the abnormal exterior joints occurred shear failure and column end hinge flexural failure; reducing beam height through adding H-shaped steel in the beam of abnormal exterior joint could improve the crack resistance and ductility; the abnormal interior joints with different staggered heights occurred column ends flexural failure; the joint with larger staggered height had the higher bearing capacity and stiffness, but lower ductility. The concrete compression strut mechanism is still applicable to the abnormal joints in TPP, but it is affected by the abnormal characteristics.
