Through the study on judgment of Body form and settle Energy flow(立形定氣) before diagnose the patients, the results are as follows. The observation of the body form is to determine prosperity and deficiency of each internal organ. It is necessary to distinguish Body form loss(形脫) and Body form fullness(形充). Fat man(肥人), Thin man(瘦人), Creamy man(膏人), Muscular man(肉人), Small Fat man(脂人) are discriminated by fat distribution, fat content, and muscle mass. The observation of the body form means the observation of structure disorder, color change, develop part at body, head and face. The observation of the body form that is to determine prosperity and deficiency of each internal organ is from the limited knowledge of the anatomy. The observation of face color is considered by blood perfusion, blood oxygenation and accumulation of carotinoid, bilirubin and change of melanin in the facial skin. The prosperity and the deficiency of energy flow is considered by symptom combined with growth (<40 years) and aging (>40 years). The prosperity of energy flow includes the anger, anxious emotion and the deficiency of energy flow includes the fear, depressive emotion. The breathing type is expiratory exhalation like asthma patients in the prosperity of energy flow. The deficiency of energy flow is weakness to overcome the disease. The prosperity and the deficiency of energy flow are considered by body metabolic ratios (Basal metabolic Rate: BMR, Resting metabolic rate: RMR, Physical activity ratios: PASs). Development of subcutaneous fat is good in the person of prosperous energy flow. The person of prosperous energy flow is hard to overcome to heat weather than cold weather. The person of deficiency of energy flow has tendencies of low blood pressure, insufficiency of blood flow in the peripheral and being shocked. The person of deficiency of energy flow has tendencies of chronic fatigue syndrome or automatic nerve disorder. If the patient who has deficiency of energy flow has severe weight loss should be checked for the presence of disease. The observation of small and large of bone is to check the development and disorder of bone growth and aging. The observation of thickness and weakness of muscle is to check the development of muscle, particularly biceps, gastrocnemius, and rectus abdominal muscle. The observation of thickness and weakness of skin is to check the ability of regulating body temperature by sweating.

J$\bar{i}$n ji$\acute{e}$(根結) has been recognized as one of a meridian pathway. If you want to study a defense qi(衛氣) and nutrient qi(營氣)'s nature, function and operation, you could find a relationship of J$\bar{i}$n ji$\acute{e}$(根結) and the defense qi(衛氣). We proposed that, especially, J$\bar{i}$n ji$\acute{e}$(根結) has got a close relationship with a operation of the defense qi(衛氣). The ji$\acute{e}$(結) of three yang(三陽) located in ears and eyes, that are a starting point of the defense qi(衛氣) operation in the daytime and a one of five sense organs(五官). Gin, Liu, Zou and Ru (根, 溜, 注, 入) of the three yang(三陽) distinguished between the three yang(三陽) in the extremities. and in the symptoms of a disease of the three yang(三陽) on the bolt - leaf - hanges(關闔樞) theory, Greater yang(太陽) is related to the skin and flesh, Yang brightness(陽明) is related to the flesh and Lesser yang(少陽) is related to the muscle or bone. These skin, flesh, muscle and bone belonged to the five bodies(五體). The five bodies(五體) have relationship with the defense qi(衛氣)'s operation and function part. The ji$\acute{e}$(結) of three yin(三陰) located in neck, chest and abdomen. If we could catched the concepts on the ji$\acute{e}$(結) of three yin(三陰) and The Gin, Liu, Zou, Ru and ji$\acute{e}$(根, 溜, 注, 入, 結) position of three yang(三陽) altogether, we could suggested the theory of the entire area completed in the surface of body. so the defense qi(衛氣)'s protecting function of the whole body surface is achieved. In the symptoms of a disease of the three yin(三陰)'s the bolt - leaf - hanges(關闔樞) theory, greater yin(太陰) and reverting yin(厥陰)'s symptoms indicates the defense qi(衛氣)'s main action of a chest and abdomen. And lesser yin(少陰)' symptoms is about a vessle, that is not to mention on the five bodies(五體) of the three yang(三陽)'s symptoms, so here is mentioned the relationship of the defense qi(衛氣) and the five bodies(五體) strengthened. In the "J$\bar{i}$n ji$\acute{e}$ chapter(根結編) of Lin Shu(靈樞)", as the meridians of the foot (足經) was described, except the meridians of the hand(手經), it is reasonable to infer that the defense qi (衛氣) is relevant to the meridians of the foot(足經) than the meridians of the hand(手經).

This study was intended to provide basic information which might be useful in increasing added values to the pork from Korean native black pigs (KNP), through comparative evaluation on carcass characteristics and meat qualities between KNP and four exotic breed groups including Duroc (DD), Landrace (LL), Yorkshire (YY), and LYD-cross (1/4LL 1/4YY, 1/2DD), and the results were summarized as follows. Live weight carcass weight, dressed meat weight, skin weight, fat weight and bone weight of KNP were significantly (p<0.05) lower than those of DD, LL, YY and LYD-cross. Carcass yield and dressed meat yield were also significantly (p<0.05) lower in KNP than other 4 groups, however, total fat, skin, bone, kidney and kidney fat in percentage were significantly (p<0.05) higher for KNP than others. Dressed meat yield was highest for YY, followed by LYD-cross and KNP. Weight of belly was 6.12, 9.43, and 9.52 kg for KNP, YY and LYD-cross, respectively. Percent belly of KNP was $11.11\%$ while other groups ranged from 11.5 to $12.2\%$ Shear force value was not different among the treatments. KNP had significantly (p<0.05) lower water holding capacity (WHC), and cooking loss, but significantly (p<0.05) higher in juiciness comparatively. KNP had significantly (p<0.05) higher $a^{*}$ value while DD had significantly (p<0.05) lower than other breeds.

Proton therapy using the Bragg peak is one of the radiation therapies and can deliver its maximum energy to the tumor with giving least energy for normal tissue. A cross-sectional image of the human body taken with the computed tomography (CT) has been used for radiation therapy planning. The HU values change according to the tube voltage, which lead to the change in the boundary and thickness of the anatomical structure on the CT image. This study examined the changes in the Bragg peak of the brain region according to the thickness variation in the head phantom composed of several materials using the Geant4. In the phantom composed of a single material, the Bragg peak according to the type of media and the incident energy of the proton beams were calculated, and the reliability of Geant4 code was verified by the Bragg peak. The variation of the peak in the brain region was examined when each thickness of the head phantom was changed. When the thickness of the soft tissue was changed, there was no change in the peak position, and for the skin the change in the peak was small. The change of the peak position was mainly changed when the bone thickness. In particular, when the bone was changed only or the bone was changed together with other tissues, the amount of change in the peak position was the same. It is considered that measurement of the accurate bone thickness in CT images is one of the key factors in depth-dose distribution of the radiation therapy planning.

The purpose of this study is to evaluate the biomechanical properties of fractured adjacent soft tissue during closed reduction after forearm fracture using the finite element method. To accomplish this, a finite element (FE) model of the forearm including soft tissue was constructed, and the material properties reported in previous studies were implemented. Based on this, nine finite element models with different fracture types and fracture positions, which are the main parameters, were subjected to finite element analysis under the same load and boundary conditions. The load condition simulated the traction of increasing the fracture site spacing from 0.4 mm to 1.6 mm at intervals of 0.4 mm at the distal end of the radioulnar bone. Through the finite element analysis, the fracture type, fracture location, and displacement were compared and analyzed for the fracture site spacing of the fractured portion and the maximum equivalent stress of the soft tissues adjacent to the fracture(interosseous membrane, muscle, fat, and skin). The results of this study are as follows. The effect of the major parameters on the fracture site spacing of the fractured part is negligible. Also, from the displacement of 1.2 mm, the maximum equivalent stress of the interosseous membrane and muscle adjacent to the fractured bone exceeds the ultimate tensile strength of the material. In addition, it was confirmed that the maximum equivalent stresses of soft tissues(fat, skin) were different in size but similar in trend. As a result, this study was able to numerically confirm the damage to the adjacent soft tissue due to the fracture site spacing during closed reduction of forearm fracture.

Purpose : The aim of this study is to find a method to diagnose and treat children who showed benign hemophagocytic histiocytes in bone marrow examination. Methods : We analyzed the clinical data of thirty patients retrospectively who showed benign hemophagocytic histiocytes in bone marrow examination from January 1995 to November 2001 at Keimyung University Dong-san Hospital. Bone marrow histiocytes were classified into a few, some, and many according to the number of histiocytes comparing with the white cells. Results : The age of thirty patients ranged from two months to 15 years. The median age was 5.6 years with male predominance(2.3 : 1). The most frequent clinical manifestation was fever; others were respiratory symptom, hepatosplenomegaly, lymphadenopathy and skin rash(in order of frequency). Common laboratory findings were leukopenia, thrombocytopenia, anemia and abnormal liver function test. Infection was present in 30 patients; causative organisms were documented in 15 patients, and bacterial infection was more common. Epstein Barr virus was the cause of infection in four patients. Bone marrow examination showed a few(20.0%), some(75.0%) and many(30.0%) hemophagocytic histiocytes. Combination immunochemotherapy including immunoglobulin, steroids and cyclosporine were helpful in 22 out of 30 patients. The mortality rate was high in young patients who showed some to many hemophagocytic histiocytes. Conclusion : Bone marrow examinations and early detection of histiocytes will be helpful in children who have fever, hepatosplenomegaly and abnormal liver function test. Immunochemotherapy were helpful and further investigation will be needed for the detection of the relationship between the bone marrow findings and prognosis.

Purpose: To report the clinical results and efficacies of one stage reverse lateral supramalleolar adipofascial flap for soft tissue reconstruction of the foot and ankle joint. Material and Methods: We performed 5 cases of one stage reverse lateral supramalleolar adipofascial flap from Jan 2005 to Sept 2005. All patients were males and mean age was 50(36~59) years old. The causes of soft tissue defects were 1 diabetic foot, 2 crushing injuries of the foot, 1 open fracture of the calcaneus, and 1 chronic osteomyelitis of the medial cuneiform bone. Average size of the flap was 3.6(3~4)${\times}$4.6(4~6) cm. All flaps were harvested as adipofascial flap and were performed with the split-thickness skin grafts (STSG) above the flaps simultaneously. Results: All flap survived completely and good taking of STSG on the flap was achieved in all cases. There were no venous congestion and marginal necrosis of the flap. In diabetic foot case, wound was healed at 4 weeks after surgery due to wound infection. There was no contracture on the grafted sites. Ankle and toe motion were not restricted at last follow up. All patients did not have difficulty in wearing shoes. Conclusion: The reverse lateral supramalleolar adipofascial flap and STSG offers a valuable option for repair of exposure of the tendon and bone around the ankle and foot. Also one stage procedure with STSG can give more advantages than second stage with FTSG, such as good and fast take-up, early ambulation and physical therapy, and good functional result.

Purpose: The basic vascular anatomy and versatility of the anterolateral thigh flap was reported firstly by Song in 1984 and then by Zhang who introduced the reverse flow pattern of this flap. In this case, the authors reviewed various articles and their experiences with the distally based anterolateral thigh flap and applied it for coverage of bone-exposed wound occurred at the distal of the disarticulated knee stump. We consequently reported the reliability and resourcefulness of this flap in the difficult and limited situation. Methods: A 67-year-old-man who had suffered from arteriosclerotic obliterans inevitably underwent the disarticulation at knee joint due to clinical deterioration. He presented to our clinic with soft tissue necrosis and bone exposure at the stump. We debrided the wound and conducted the distally based anterolateral thigh island flap by transecting proximal portion of descending branch of the lateral circumflex femoral artery and the $14{\times}10cm$ sized flap was transferred to cover the defect. The pedicle measured 14 cm in length with pivot point 7 cm above the patella. Results: The postoperative course was mainly uneventful except early venous congestion for 4 days and subsequent partial skin loss. The wound was healed by secondary intension and no other sequelae had been observed during follow-up period of 12 months. Conclusion: Despite the presence of various reconstructive choices, the distally based anterolateral thigh island flap can be designed to repair soft tissue defects around the knee region, providing its reliable blood supply and long pedicle length, especially in the challenging cases.

The conservative treatment of the condylar fracture has been used for a long time because of its simplicity, good prognosis and less complication. Traditionally the conservative treatment has been carried out by maxillomandibular fixation using arch bar and wire. But a simplified technique of maxillomandibular fixation introduced here is a procedure that 4 bone screws are placed above the apecies of the maxillary and mandibular canines and then ipsilaterally placed maxillary and mandibular bone screws are linked by a loop of wire each other. This procedure has several advantages compared with the traditional maxillomandibular fixation method. 1) it provides simplicity for the operators. 2) it sustains maxillomandibular fixation more rigidly compared with arch bar technique. 3) it keeps stable maxillomandibular fixation in the region of the anterior teeth so that anterior open bite tendency can be remarkably minimized. 4) it does not injure the periodontal tissue because the teeth are not engaged and causes less discomfort to the patient. 5) it decreases the possibility of operator's AIDS infection through inadvertent skin puncture. 6) it is highly recommended for the patients whose teeth are available for maxillomandibular fixation. The two male patients were diagnosed as bilateral condylar and symphyseal fracture of the mandible. They restored stable occlusion and functional mandibular movement only by a simplified technique of maxillomandibular fixation.

Purpose: Many fingertip injuries are associated with nail injury and it is hard to repair to original shape due to its unique characteristic. Mucosal graft is used for a defect of the nail bed injury. Hereby, we introduce a DAP flap and buccal mucosal graft, with which we could reduce the defect size of the injured fingertip and donor site morbidity at the same time, without any need for harvesting additional skin from other part of hand. Also, mucosal graft makes good cosmetic and functional outcome of nail. Methods: This method was performed in a 56-year-old man with fingertip injury on dorsal side of left thumb due to electrical saw. First, DAP flap was performed on the injured finger to reduce the size of the defect of fingertip and cover the bone exposure. Second, nail bed part of the DAP flap was de-epithelized and buccal mucosal graft was done from left side of intraoral cavity wall. Results: Flap and graft survived without any necrosis but some nail bed could not be covered with flap due to insufficient flap size. All wounds healed well and did not present any severe adversary symptoms. Conclusion: DAP flap with mucosal graft is an effective method that we can easily apply in reconstruction of fingertip injury. We suggest that the combination of the two procedures makes good functional and cosmetic outcome compared to the usual manner, especially in cases of nail bed injury without distal phalanx bone defect.
