  • The interior vehicle noise due to the exterior aerodynamic field is an important topic in the acoustic design of a car. The air flow detached from the A-pillar and impacting the side windows are of particular interest as they are located close to the driver / passenger and provides a lower insulation index than the trimmed car body parts. This paper presents a numerical analysis method for a simplified vehicle model. The internal air cavity including trim component are included in the simulation. The car body includes the windshield and two side windows. The body is made of aluminum and trimmed with porous layers. The methodology proposed in this paper relies on two steps: the first step involves the computation of the exterior flow and turbulence induced non-linear acoustic field using CFD Code. The second step consists in the computation of the vibro-acoustic transmission through the window using the finite element vibro-acoustic solver Actran.

  • Greater yang disease(太陽病) is a syndrome induced by peripheral obstruction. One of them is "wind stroke(中風)" with the obstruction in lymphatic system. The other obstruction appearing on circulatory system is called "cold damage(傷寒)." Kyejitang(桂枝湯) is the formula prescribed for greater yang wind stroke pattern(太陽中風證) which is caused by peripheral lymphatic duct obstruction. Ramulus Cinamoni acts as a vasodilator and Radix Paeoniae relieves the abdominal tension. They make blood move to the internal organ and this can remove the retention of peripheral lymphatic system. Covering the patient with a blanket and getting him/her to have hot and thin rice gruel causes slight Diaphoresis, contributing to relieving the retention of lymphatic system. Disharmony between nutrient and defense(營衛不和) means that pressure becomes different between lymphatic system and vascular system. Kyejitang(桂枝湯) is called releasing muscles formula(解肌劑) because it can resolve such pressure difference. Diaphoresis is not a means to eliminate pathogenic qi(邪氣) from the body. That is the syndrome proving that the body fluid has moved around when disordered fluid distribution is corrected. Therefore, diaphoresis should be induced weakly all the time. If diaphoresis is induced excessively, body fluid will move more than desired and then illness cannot be cured. In Sanghanlun(傷寒論), dispersing drugs aim at addressing the retention in the exterior field, but it actually applies to the entire exterior and interior to make body fluid move. Therefore, diaphoresis does not just act on exterior field, and freeing the stool does not only apply to interior field. Distribution of body fluid changed by pathogenic qi(邪氣) influences the whole body because the human body has a closed circulatory system. Sanghanlun(傷寒論) has included treatments for pathogenic disease. However, its value should not be limited to pathogenic disease. It is because controlling blood flow by sending body fluid to the place a doctor wants is certainly worth using for treatment of non-exogenous disease or chronic illnesses.

  • Objectives : This paper contemplates how the special features found in Moyuan as revealed in Wenyilun has continued from the Moyuan concepts of past includig Huangdineinjing. The author of this paper attempted to distinguish common and different points between the two, and how these features changed in the following generations. Methods : The concept of Moyuan as revealed in Huangdineinjing is first reviewed before laying out the concepts of Moyuan in Wenyilun by different categories. These two concepts are then compared. A Chinese medicine literature database is used in continuing this study, and materials are selected with relation to the special features of Moyuan. Results : The special feature of half-exterior half-interior found in the Moyuan in Wenyilun is similar with that in Neijing in that they both thought Moyuan existed between the stomach, the lungs, and the five organs. The concealability of Moyuan is similar with the explanation of Moyuan in Suwen nuelun, and it is related with the story of Gaohuang in Chunqiu Zuozhuan. Compared to the fact that the concept of Moyuan in Neijing is explained as that pathogenic factor enters the surface of the body in sequence, the concept of Moyuan in Wenyilun is conveyed in that the pathogenic factor conceals itself first before being divided into exterior and interior. Moyuan is also related to upright qi, and Gaohuang-yuan: origin of Gaohuang, too, is connected Shenjiandongqi: the energy that moves between the two kidnets, and also the triple burner. Conclusions : The concepts of "Half-exterior Half-interior", concealability, and "divide it into several places in half-exterior", and upright qi contained within the Moyuan in Wenyilun are studied for their origins, and this effort is anticipated to be greatly helpful in both understanding the historical contexts of Wuyouke Wenyilun and conducting studies on clinical application of Moyuan theory.

  • This research is purposed to find methods of treatment on allergy diseases, through summarizing thought on human and etiology, classification and treatment on diseases proposed in Sasang constitutional medicine 2. Methods of Research It was researched as bibliologically with Dong-mu's chief medical writings such as ${\ulcorner}$Dongyi Soose Bowon(東醫壽世保元)${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun(東醫壽世保元四象草本卷${\lrcorner}$ 3. Results and Conclusions 1. Dong mu thought that human is composed of Heart that inside preserve soul and Body that outside respond to Affairs-Objects. 3. The cause of disease is classified into interior cause and exterior cause. Interior cause could be used in cause of disease, exterior cause could be used in prevention of illness, treatment of disease and preservation of health. 4. The treatment of disease proposed in ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun(東醫壽世保元四象草本卷${\lrcorner}$ is that it is to recover 'Essential Qi of Constitution(體質正氣)' by medicine and management of 'Mind-Body(心身)' and that chronic disease is treated chiefly by management but acute disease is treated chiefly by medicine. 5. Allergy disease should be prevented by management of 'Mind-Body(心身)'. but if we suffer from allergy disease, we should treat disease through recovering 'Essential Qi of Constitution(體質正氣)' both medicine and management of 'Mind-Body(心身)'.

  • 1. Objective This study is aimed to present the effective classification of Soeumin symptomatology and the standardized signs for classification which can be applied for KCD, ICD and the insurance codification system. 2. Methods 1) Differentiate Soeumin symptomatology based on exterior-interior patterns, favorable-unfavorable patterns, and mild-severe-dangerous-urgent patterns. 2) Investigate the standard signs and symptoms to claasify Soeumin symptomatology based on exterior-interior patterns, favorable-unfavorable patterns, and mild-severe-dangerous-urgent patterns. 3. Results and Conclusions 1) The diagnosis criteria for Soeumin exterior-interior disease is based upon signs & symptoms of cold/heat, condition of stool, state of digestive system(such as digestion and appetite)among others. 2) The diagnosis criteria for Soeumin favorable-unfavorable disease is generally based upon whether the vital force of the spleen is damaged or not. More specifically, for the exterior disease, whether or not sweating is present. For the interior disease, whether or not dry mouth, body ache(a main symptom of the exterior state), and anxiousness are present. 3) For the Soeumin Wool-gwang disease, the diagnosis criteria of mild-severe disease is whether or not chills is present and the degree of body fever. 4) For Soeumin Mang-yang disease, the diagnosis criteria of dangerous-urgent disease is whether or not chills is, the degree of sweating and urine condition. 5) For the Soeumin Greater-Yin disease, Abdominal-pain bowel irritability pattern and Epigastric discomfort pattern are early state signs, Jaundice pattern is mild-state sign, edema & Greater-Yang disease Yin-toxin pattern are terminal state signs. 6) For the Soeumin interior disease, Abdominal-pain bowel irritability pattern and Epigastric discomfort pattern are of the dangerous state pattern, Jang-gual and Exuberant-Yin-repelling-Yang pattern are of the urgent state patterns.

  • 1. Objectives: We aimed to propose a sub-classification system for the Taeeumin symptomatology by examining the Taeeumin pathology and symptomatology descriptions appearing in "Donguisusebowon". 2. Methods: The Gabo Edition and the Sinchuk Edition (the upgraded and revised edition) of "Donguisusebowon" were reviewed and examined for relevant information on the Taeeum pathology and symptomatology. 3. Results and Conclusions: 1) In the Taeeumin symptomatology, the Exterior disease develops from the basic pathology of Esophagus-Cold and the Interior disease from that of Liver-Heat, eventually progressing to damage of the expirational and dispersive energy of the Lung Sector, the Prime Core Organ or the excessively small organ of the Taeeum constitutional type. The resulting pathology can be broadly defined as the "Lung-Dryness symptomatology". 2) The case reports introduced in the Exterior disease section, including the Zhang Zhongjing Mahuang-tang treatment, Prolonged-affliction disease treatment, and Exterior disease Pestilential disease treatment, share several points in common. They all arise from the pathology of "weakness in the Lung sector and deficiency in the Exterior sector", and they can all be assigned to the same symptomatological division that presents with systemic heat and cold intolerance; this symptomatology can be defined as the "Esophagus-Cold symptomatology", the milder subdivision of the exterior symptomatology. 3) The body of text appearing in the last part of the Interior disease section commonly referred to as the "Taeeumin Conspectus" is in fact not a conspectus when its contents are actually examined. Instead, it can be understood from its pathological and symptomatological descriptions that the passage is explaining the more severe subdivision of the exterior symptomatology that has progressed from Esophagus-Cold to a pathology characterized by damaged expirational and dipersive energy of the Lung Sector. 4) The relocation of the "dry-related pathology" indicates a change in perspective regarding the "Dry-related symptomatology", which caused the rearrangement of the Interior disease into divisions of Liver-Heat symptomatology that is characterized by fulminant heat pathology and Dry-Heat symptomatology that is also accompanied by Lung-Dryness. 5) The Interior disease Yin-Blood Consumptive symptomatology should be included in the Dry-Heat symptomatology in the pathological scheme. 6) Based on the above, the subdivisions of the Taeeumin symptomatology should be arranged as "Esophagus-Cold symptomatology" and "Lung-Dry-Cold symptomatology" in the Exterior disease and "Liver-Heat symptomatology" and "Dry-Heat symptomatology" in the Interior disease.

  • In an ordinary CT scan, a large number of projections with full field-of-view (FFOV) are necessary to reconstruct high resolution images. However, excessive x-ray dosage is a great concern in FFOV scan. Region-of-interest (ROI) CT or sparse-view CT is considered to be a solution to reduce x-ray dosage in CT scanning, but it suffers from bright-band artifacts or streak artifacts giving contrast anomaly in the reconstructed image. In this study, we propose an image reconstruction method to eliminate the bright-band artifacts and the streak artifacts simultaneously. In addition to the ROI scan for the interior projection data with relatively high sampling rate in the view direction, we get sparse-view exterior projection data with much lower sampling rate. Then, we reconstruct images by solving a constrained total variation (TV) minimization problem for the interior projection data, which is assisted by the exterior projection data in the compressed sensing (CS) framework. For the interior image reconstruction assisted by the exterior projection data, we implemented the proposed method which enforces dual data fidelity terms and a TV term. The proposed method has effectively suppressed the bright-band artifacts around the ROI boundary and the streak artifacts in the ROI image. We expect the proposed method can be used for low-dose CT scans based on limited x-ray exposure to a small ROI in the human body.

  • Traditional Medicine (TM) is called as philosophical medicine in Korea. An unified theory named as Sihnsang-hanron (SSHR) was hypothesized through studies of scientific analyses on various theories of TM. SSHR has extracted seven concepts which are six common ones from the great three books (三大原典) and the Logic of Laotzu & Chuangtzu (老莊思想). Six common concepts are the affecting by cold (傷寒), qi (氣), cold or heat (寒熱), exterior & interior of body (表裏), deficiency or excessiveness (虛實), and yin & yang (陰陽). We have tried to apply these seven concepts to Physics and Life Science. The affecting by cold means anti-sunlight and the origin of all diseases. The difference between TM and modern medical science would be in diagnostic methods as well as their theoretical analyses for various diseases. The modern science follows Haeckel's positive dialectics applied by the biological monism, and oriental one(SSHR) does Yin-Yang monism from the studies of Logic of Laotzu (老子) & Chuangtzu (莊子). SSHR would make the theory of exterior & interior of body (表裏論) and six channels (六經) develope scientifically as a diagnostic technique of disease. This theory is an excellent one that can't be found out in modern medical science, and so it should be developed as a scientific theory by using modern mechanic instrument. Chuangtzu asserted that ai was the basic substance of the universe. It is hypothesized that qi (氣) is like small particles -higgs, with dynamic power in modern Physics. We consider cautiously qi could be calculated by mathematics through higgs' bosons in near future.
