The following conclusions are drawn from Hyungsang medicinal review on th globs hystericus through Donguibogam and other literatures. The globs hystericus appears in the throat and the epigastric region. It is a subjective sensation as if a plum pit is stick in the throat and is compressed, usually ac companied by stuffiness in chest, depression, nausea, and hiccup. But the throat is not marked with redness and swelling. Because Gi stagnation due to seven emotions is the main cause, the globs hystericus is usually followed by Seven Gi injuries, Pain and depressive syndrome due to disorder of Gi, palpitation due to fright, continuous violent palpitation, Gi phlegm, precordial pain with palpitation, epigastric pain due to seven emotions, cough and dyspnea due to disorder of Gi, and six kinds of stagnations. When head and body or chest and abdomen is compared to heaven and earth, the blockage of Gi between heaven and earth is common to the persons with the following charcteristics in Hyungsang; Dam type rather than Bankwang type, Gi type and Shin type rather than deer type and fish type, Taeum and Yangmyeong meridian types out of six meridian types, manly women, womanly man, too long or short neck, and signs of stagnation between the eyebrows. The globus hystericus needs, distinguishing from aphonia, acute tonsilitis, goiter, and pectorial pain with stuffiness. The affected area of aphonia and acute tonsilitis is the throat but they are not cause by the disturbance of seven emotions. Goiter can be distinguished by the changes in the appearance of neck. Even though the symptoms are similar, globus hystericus is caused by the stagnation of Gi, but the pectorial pain with stuffiness, by the insufficiency of the Heart blood. The general prescriptions are Chilgitang, Sachiltang, Gamisachiltang, Gamiijintang, and Sinihwan.

The study was to investigate kinematic difference between flexed and extended type of knee during Jigeo-Cha-Gi in Taekwon-Do. For this subjects participated were consisted of weights of fin (1), bantam (1) and welter class(1) of male 3 national representative level skilled in two type(flexed and extended type) of Jigeo-Cha-Gi. 3D cinematography analysis was performed for motion analysis and Kwon 3D ver. 3.1) was used for 3D coordinates & analysis variables calculation. In Temporal variable there was no significant difference statistically in all phases & total elapsed time between flexed and extended type, but flexed type was delayed more 0.016 sec than extended type. In displacement of COG there was significant difference in level of p<.05 showing longer mean 6.13 cm in case of flexed type than extended type in displacement of COG during all phase and too significant difference in level of p<.01 showing longer mean 4.4 cm in case of flexed type than extended type in displacement of COG in follow through phase. In velocity of COG there was significant difference in level of p<.001 showing higher mean 15.53cm/s in case of flexed type than extended type in velocity of COG(Y direction) during targeting phase and peak velocity(Y) was more fast 8.74 cm/s in extended type than flexed type. In velocity of leading leg in forward direction(Y) there was significant difference in level of p<.05 showing higher thigh mean value in case of flexed type than extended type but showing higher foot mean value in extended type at level of p<.001 than flexed type in velocity of COG(Y direction). In velocity of leading leg in vertical direction(Z) there was no significant difference in the second & third phase in case of vertical velocity level, but momentum transferred efficiently form proximal to distal endpoint. In front-back & right-left orientation angle of trunk there was possibility of more stable Jigeo-Cha-Gi in extended than flexed type by decreasing in right-left orientation angle of trunk. In relative angle of lower leg(hip, knee, ankle) there was significant difference in level of p<.001 showing longer mean 32.74 deg. in case of flexed type than extended type in hip joint during the second phase but maintained insufficient extended knee of mean 168 deg. in targeting phase.

The followings are concluded from the treatment of headache in Hyungsang medicine, focussed on 11 kinds of headaches in Donguibogam. Headache is classified into overall headache and migraine according to the affected region. The causes are divided into exogenous affection and internal injury; The former brings on headache due to Wind-Cold and headache due to Damp-Heat. The latter, reversal headache, headache due to adverse rising of phlegm, headache due to regurgitation of Gi, headache due to excessive Heat, headache due to excessive Damp, true headache, and alcoholic headache. Headache due to internal injury generally tends to show deficiency syndrome with external affection. Headache due to exogenous affections is common to those who have big head or white skin and to Bangkwang type, and woman. The primary causes are Wind-Cold and Wind-Heat. When the body is observed in the perspective of eight phases, Damp-Heat is to be produced in the front, and Dry-Damp, in the back. Headache due to Damp-Heat is susceptible to Yangmyeong meridian type whose body develops more in the front and to woman. In the perspective of the upper and the lower, Yangdu(that is, head) is related to Eumdu(that is, glans of penis). Headache is also caused by the problems of Eumdu ,such as deficiency of Essence in man, pathologic change of uterus in women, and San syndrome in lower abdomen. In the case of man, headache is frequently severe and difficult to treat because head is a root for man. Disharmony of Gi and blood between the right and the left brings out migraine and headache due to regurgitation of Gi. Migraine is usually accompanied by symptoms of exogenous affection and often afflicts Gi-type, Shin-type, Soyang meridian type, deer type, and Dam-type. Headache due to regurgitation of Gi is brought by Gi deficiency or blood deficiency so that symptoms of exogenous affection do not show. It is mainly common with old people and those who have sunken eyes induced by deficiency of stomach Gi. In the perspective of the upper, the middle, and the lower, the pathologic change of head, chest and abdomen also bring about headache. The pathologic cause of head is Wind-Heat ,which triggers overall headache, migraine, headache due to Wind-Cold, headache due to excessive Heat, The pathogen of chest is phlegm-Fire and brings out headache due to Damp-Heat and headache due to adverse rising of phlegm. The pathologic factor in abdomen is Cold-Damp and produces headache due to adverse rising of phlegm and headache due to excessive Damp. In case of women, headache is generally caused by phlegm-Fire and retention of undigested food.

Objectives : The quotation of Seongyeong found in the chapter of danjeonyusam in Donguibogam uses a type of allocation of Gi(氣), Sin(神), and Jeong(精) each in Upper, Middle and Lower, three Danjeon, that is different from the type was widely accepted at the time. The paper attempts to interpret this in a new way. Methods : The paper collected the understanding of Jeong-Gi-Sin found in the Korean medicine based on Naedan Theory of Taoism, and tried to approach and structurally analyze the contents of Seongyeong, Ojinpyeonju, and Hwanggeuggyeongseseo found in Donguibogam's danjeonyusam. Results : The control of the body by Gi stored in Upper Danjeon is related to brain function, control of Gi at Lower Danjeon which preserves Jeong in Kidney is related to proliferation of Original Qi from kidney region throughout the body by triple energizers. Sin located at Middle Danjeon is contrasted with Jeong in Lower Danjeon, and Sin controls activity of life in the part between body and Gi. Conclusions : A new understanding on the assignment of Jeong-Gi-Sin in Seongyeong is possible, and it is expected to contribute to the future study of Korean Medicine and Taoism.

To complement and develop the Orient Medical Bian Zheng treatmemt(韓方辨證施治), I have observed and analysed 68 persons who have recieved medical treatment because of the epigastric pain. Considering and analysed the Clinical Diagnosis(臨床診斷) and Clinical Bian Zheng(臨床辨證), Clinical Diagnosis(臨床診斷) and Gastroscopic Bian Zheng(微觀辨證), Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證), case history, age and sex, I have obtained the conclusion as follows. 1. The frequency of epigastric pain according to the classfication of Clinical Bian Zheng(臨床辨證) most occured in Gi Che Zheng(氣滯證), then in Huh Han Zheng(虛寒證). and least in Wi Youl Zheng. 2. There is no clear connection between the Clinical Bian Zheng(臨床辨證) and Clinical Diagnosis(臨床診斷). 3. The frequency of the epigastric pain according to Gastroscopic Bian Zheng(微觀辨證), mainly occurred in Wi youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷滯型)and then occurred in Wi Han Type(胃寒型), and least occurred in Wi Rac A Che Type(胃絡瘀滯型) 4. Having observed the relation between the Gastroscopicin Bian Zheng(微觀辨證), and Clinical Diagnosis(臨床診斷) as pathological process, I have obtained the result that Wi Youl type(胃熱型) and Wi Rac Jac Sang Type(胃絡灼傷型) mainly occurred in Erosive Gastritis and Superficial Gastritis at the early stage, and Wi Rac A Che Type(胃絡瘀滯型) occurred in the whole stage among the Wuperficial Gastritis, Atro pic Gastritis, and Erosive Gastritis, Gastric Cancer, and the Wi Han Type(胃寒型) mainly occurred in Atropic Gastritis at the later stage. 5. The relation between Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證) do not coincide. 6. Observing the relation between the Clinical Bian Zheng(臨床辨證) and case history, Gi Che Zheng(氣滯證), Huh Han Zheng(虛寒證), Wi Youl Zheng(胃熱證) were commonly seen in the early stage of the case history, and Eum Huh Zheng(陰虛證) and Houl A Zheng(血瘀證) were seen in every stage. 7. Observing the relation between the Clinical Bian Zheng(臨床辨證) and age, Gi Che Type(氣滯型) was mostly seen in the thirties and other Bian Zheng(辨證) was seen after the middle 8. Observing the relation between the Clinical Bian Zheng(臨床辨證) and sex, Gi Che Type(氣滯型) was seen at high ratio in both sexes. 9. Observing the relation between the Gastroscopic Bian Zheng(微觀辨證) and case history Wi Han Type(胃寒證), Wi Youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷型) were seen in the early stage of the case history Wi Rac A Che Type(胃絡瘀滯型) was mostly seen in the later stage. 10. There was no clear connection between the Gastroscopic Bian Zheng(微觀辨證) and age, sex. Although the examples were not sufficient, recipe regarding the partial variation state of stomach mucos together with Orient Medical Bian Zheng(韓方辨證) treatment seems to be useful in the effective treatment of Bi wi(脾胃) disease besides the epigastric pain.

After analyzing the cases of treating female patients troubled with morbid leukorrhea, the writer drew the conclusions as follows. The shapes of patients with morbid leukorrhea show a large number of shapes of Gi type, Sin type or being inclined to be vigorous Gi, to have depressive syndrome due to disorder of Gi, to be Fire's nature flared upward, to become retention of phlegm and fluid, to become retention of Gi or to become retention of heat, or San syndromes. Accompanied syndromes of morbid leukorrhea appear over the body of upper, middle or lowe portion. In lower cho, the symptoms are menopathy, menstrual irregularities, menstrual irregularities, oligomenorrhea, itching of external genitals, San syndromes, infertility, lumbago which are connected with uterus. And in the middle cho, those are indigestion, nausea, distress in the stomach, vomiting, swallowing acid connected with digestive organs. And also in the upper cho, globus hystericus, chest distress, headache, dizziness, neck stiffness, heat in the upper, pimples connected with upper cho are appeared. Among the prescriptions of treatment for morbid leukorrhea, Ijintang was applied with the widest range of all. Besides that there were mainly prescribed for symptoms such as Gamisachil-tang, Haenggihyangso-san, Gamigwibi-tang, hyangsapyeongwi-san, Onkyung-tang, Banchong-san, Yongdamsagan-tang, Sogampaedok-san, Ojeok-etc.

In this paper we present a simple and efficient robust optimal design formulation and its application to a resonant-type micro probe. The basic idea is to use the Gradient Index (GI) to improve robustness of the objective and constraint functions. In the robust optimal design procedure, a deterministic optimization for performance of MEMS structures is followed by design sensitivity analysis with respect to uncertainties such as fabrication errors and change of operating conditions. During the process of deterministic optimization and sensitivity analysis, dominant performance and uncertain variables are identified to define GI. The GI is incorporated as a term of objective and constraint functions in the robust optimal design formulation to make both performance and robustness improved. While most previous approaches for robust optimal design require statistical information on design variations, the proposed GI based method needs no such information and therefore is cost-efficient and easily applicable to early design stages. For the micro probe example, robust optimums are obtained to satisfy the targets for the measurement sensitivity and they are compared in terms of robustness and production yield with the deterministic optimums through the Monte Carlo simulation.

In this paper, we introduce a roots method that uses the roots inside the unit circle of the associated characteristics equation to evaluate the steady-state system-length distribution at three epochs (pre-arrival, arbitrary, and post-departure) and sojourn-time distribution in GI/PH/1 queueing model. It is very important for an air base to inspect airplane oil because low-quality oil leads to drop or breakdown of an airplane. Since airplane oil inspection is composed of several inspection steps, it sometimes causes train congestion and delay of inventory replenishments. We analyzed interarrival time and inspection (service) time of oil supply from the actual data which is given from one of the ROKAF's (Republic of Korea Air Force) bases. We found that interarrival time of oil follows a normal distribution with a small deviation, and the service time follows phase-type distribution, which was first introduced by Neuts to deal with the shortfalls of exponential distributions. Finally, we applied the GI/PH/1 queueing model to the oil train congestion problem and analyzed the distributions of the number of customers (oil trains) in the queue and their mean sojourn-time using the roots method suggested by Chaudhry for the model GI/C-MSP/1.
