Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

This study was undertaken to investigate the effect of orthognathic surgery on occlusal force. The maximum bite force was measured in 26 dentofacial deformity patients, aged 14-26(mean age 20.3) years, before surgery and at IMF removal, 3, 6, and 12months postsurgery. To grope the correlation of bite force and skeletal change after orthognathic surgery, the cephalometric headplates were measured, tabulated and statistically analyzed. The results were as follows. 1. The presurgical maximum bite force was 13.7kg in upper first molar(rt. Side 12.7kg, it. Side 14.6kg). There was remarkable difference with that of normal occlusion. 2. The recovery of bite force was very significant in according to the operation method and the duration of IMF that was 7.6kg at IMF removal, 14.2kg at 3 months, 19.7kg at 6 months. 26.1kg at 12 months postsurgery. 3. To fasten the recovery and to increase the bite force after orthognathic surgery, the long IMF time and the injury to the masticatory muscle should be avoided by the internal rigid fixation and early physical exercise. 4. The bite force was positively correlated to the changes of mandibular plane angle, the angle between platatal plane and mandibular plan, the angle between occlusal plane and mandibular plane, and negatively correlated to the changes of mandibular body length in craniofacial structure. 5. There was no correlationship between bit force and mesial inclination of tooth long axis of first molar in this subject. 6. There was no correlation between the changes of bite force and the changes of mechanical advantage of the temporal and masseter muscle.

Eagle's syndrome is the term given to symtomatic elogation of the styloid process or mineralization of the stylohyoid or stylomandibular ligament. Since ossification of stylohyoid ligament at cadeva was fist described by De Manchetics in 1652 and Weinlecher described clinical symptom which produced by elongated styloid process and osteotomy of styloid process in 1872, Clinical symptom which include sensation of a foreign body on the pharynx, dysphagai, dysphonia, referred pain, and mouth opening disturbance was termed by Eagle as Eagle's syndrome. then, case reports of Eagle's syndrome are presented. in these cases, the patient's chief complaints included periauricular radiating pain, mouth opening disturbance, foreign body sensation, dysphagia, tenderness on the neck. Through vairous X-ray examination and palpation of tonsillar fossa, elongted styloid process were confirmed. Under the general anesthesia there were successfully removed out via transoral approach technique, described by Eagle. after resented styloid process, they were freed from the symptoms without further complication. Therefor we reported these cases treated by surgical resection of styloid process with good results.

The purpose of this study was to investigate the dynamic response of the mandible to impact and provide insight into the fracture mechanism of the mandible, by 3-dimensional finite element method. The finite element model of the mandible was developed and calculated using NASTRAN/XL(MSC co. U.S.A.) and the linear dynamic transient analysis was performed according to the impulsive force direction, force type and impulse time to the mandible. At first, the load was applied on the mandibular symphysis, body, angle and subcondylar area in the horizontal mandibular plane and the computed stress-time histories at 14 locations of the mandible were obtained. Secondly, the impulsive force was directed to the symphyseal area with changing the force magnitude and impulse time, and calculated the node displacement at 8 locations of mandible. The conclusions from this study were as follows. 1. The appearance of impulsive energy transmission was different to the direction of impulse to the mandible. 2. The impulsive stress and deformation were large in lingual or medial side than buccal or lateral in the mandible. 3. The velocity, appearance of energy transmission and the fracture pattern in mandible were affected rather impulse time than force. 4. The horizontal impact to the one side of mandible did not have effect on the stress and displacement of contralateral mandible. From the above results, fracture pattern in symphysis can be showed as simple or comminuted, multiple or associated in body and angle and solitary in subcondyle area.

The amplification and the isolation conditions of pBR322 plasmid DNA were investigated. For the amplification of pBR322 plasmid DNA, cells from logarithmic growth phase were most effective. The optimal conditions for the amplification of pBR322 plasmid DNA in Escherichia coli GM4 were obtained as follows; 50-150 ㎍/ml of chloramphenicol concentration, 6-8 hours of incubation time in the presence of chloramphenicol. Ampicillin and tetracycline had no effect on the amplification of pBR322 plasmid DNA. Approximately 1 mg of pBR322 plasmid DNA was purified from 3.5 ℓof Escherichia coli GM4 culture broth by hydroxyapatite chromatography. The purified pBR322 plasmid DNA was expressed in Escherichia coli C600.

This paper aims to provide a way to improve dynamic stability of biped robots against undesirable disturbances and in a slope. By using an angular velocity sensor and an acceleration sensor on its waist, we can make a medium-sized biped robot walk stably in a slope against impulsive disturbances. In addition, it is possible for the robot to walk stably in an unknown slope. The measured signals from the sensor are used for compensating the reference angles of ankle, knee, and pelvis joints. Some experiments show that the stability of the robot is much enhanced by using cheap sensors and a simple algorithm. This work helps biped robots walk more stably in real environments.

This study focuses on the characteristics of the families of the mentally ill and the intervnention program for them. First, the families experience serious care burden : emotinal, behavioral, social and economic. Second, their primary needs include anxiety counseling, information on community resources, education on mental illness, etc. Third, their care burden leads to reduction of social network, resulting in the weakening of social support. Therefore social workers use various intervention methods. Especially, the uses of family education program, self-help group, and social network(support group) intervention are prevalent. Each method has its own weakness and strength. Social network intervention is better than two other methods in solving problems related to emotinal and social burden and information provision.

Tracheobronchopathia osteoplastica is a rare disorder of unknown cause characterized by the projection of numerous bony or cartilaginous submucosal nodules into the tracheobronchial lumen with sparing of the posterior membranous portion of tracheobronchial tree. In the past, most of the cases were diagnosed as secondary finding at autopsy. Nowaday, the key component of the evaluation is flexible fiberoptic laryngoscopy and bronchoscopy, which typically demonstrates irregular spicules of subrnucosal bone and cartilage projecting into the tracheobronchial lumen and causing various degrees of airway obstruction. A 45 years old man was visited Sunchon St. Carollo hospital due to discomfort on throat. We saw several nodules just below vocal cord via laryngoscope. The computed tomography revealed multiple small calcified nqdules on trachea and both main bronchi. Pathologic finding of bronchoscopic biopsy showed abnormal proliferation of bony and cartilagious nodules in the tracheal submucosa. These fingdings were consistent with tracheobronchopathia osteoplastica. We report here on a case of tracheobronchopathia osteoplastica with review of literature.

This is clinico-statistical & retrospective study of 30 patients with only unilateral mandibular condyle fracture and combined with 24 midface fracture patients who were treated with open reduction in Wonkwang University Dental Hospital during the period 1993 to 2000. The results were as follows : 1. In mandibular condyle fracture combined with midface fracture, the most incident type is associated with zygomaticomaxillary complex fracture and level Ⅳ of mandibular condyle fracture combined with ZMC fracture is the most related(33.32%). 2. In the period of intermaxillary fixation, unilateral mandibular condyle fracture group (9.8 days) is shorter than combined with midface fracture group (15.3 days), but no statistical difference between two groups(p.>0.05). 3. In the mouth opening recovery, unilateral mandibular condyle fracture group is faster than combined with midface fracture group in post-operative 1 month, but no significant difference between two-groups after 3 months postoperatively (p>0.05). 4. In two-groups, treatment method is almost open reduction with internal fixation(ORIF) and overall 25% temporary complications were shown, but little lower incidence in unilateral condylar fracture group.
