The purpose of this study was to investigate the effects of two different chung-seo-ik-gi-tang administration types on fatigue induced during 2,000 m running in 12 healthy-male elite boxer. All subjects were divided randomly with two groups, Pre-administration Group(A: N=7) and Pre- and Post-administration Group(B: N=7) and performed 2,000 m maximal running. The blood samples were collected from antecubital vein by 10ml syranges(6ml/each) at before exercise, immediately after exhaustion, recover-10 min, recover-20 min and recover-30 min. These samples were used to analyze for the level of glucose, lactate, TG, LDH, pH, HCO₃?, Na??, K??. The statistically analyzed results of various blood parameters were summarized as follow, 1. Plasma glucose were not showed significant difference between two groups. but glucose lwvel at post-exercise and rest-30 min in B group wes significantly decreased. 2. Lactate accumulation in B group was significantly decreased at post-exercise and rest-30 min.. And lactate level at rest-30 min. was showed significant difference between two gruops. 3. Serum LDH response to 2,000 m running at post-exercise and recovary periods was showed significant changes in B group. 4. Venous pH at post-exercise, HCO₃? at post-exercise and rest-30 min. in A group and pH at post-exercise and rest-10, 20 min., HCO₃? at post-exercise were showed significant changes. But there were not showed significant difference between two groups. 5. K?? level in B group was showed significant difference compared to A group. And also K?? level at rest-30 min. in B group was showed significant change. The results indicated that Chung-seo-ik-pi-tang had the effects of ergogenic aids on fatigue and recovery during 2,000 m maximal running.

The corrosion behavior of copper in neutral aerated synthetic tap water was investigated using electrochemical methods, SEM and XPS. All potentiodynamic polarization curves showed active corrosion behavior, and the corrosion rate was more sensitive to flow velocity than Cl^(-) ion concentration and temperature. The result of potentiostatic test indicated that the current density decreased with increasing time regardless of Cl^(-) ion concentration and temperature in stagnant condition because copper compounds were formed uniformly on the surface. The EIS plot was changed from two time constants to three time constants with the formation of Cu₂O, and the charge transfer resistance (R_(ct)) was very large and increased with increasing immersion time. From all results, copper had good corrosion resistance in this potable water system.

A neural network approach has been developed to determine the depth of a surface breaking crack in a steel plate from ultrasonic backscattering data. The network is trained by the use of feedforward three-layered network together with a back-scattering algorithm for error correction. The signal used for crack insonification is a mode converted 70˚ transverse wave. A numerical analysis of back scattered field is carried out based on elastic wave theory, by the use of the boundary element method. The numerical data are calibrated by comparison with experimental data. The numerical analysis provides synthetic data for the training of the network. The training data have been calculated for cracks with specified increments of the crack depth. The performance of the network has been tested on other synthetic data and experimental data which are different form the training data.

The separation of symphysis pubis as a result of injury is uncommon, but it is increasing in number in parallel with today's speedy development of car industry. Most cases of the separation of symphysis pubis are amenable to closed treatments, but unstble separation where the reduction is difficult to maintain may require open techniques. Authors analyzed 27 cases of traumatic separation of symphysis pubis with 16 months follow-up on an average, who had been treated at the Orthopaedic Department, Chosun University Hospital. The results obtained were as follows; 1. The most common cause was traffic accident (81.5%). 2. Among of 27 patients, instability on the posterior stabilizer of pelvic bone was noticed in 18 patients. 3. Fifteen patients were treated with closed methods(bed rest, hammock, traction)and twelves were treated by the open reduction and internal fixation. 4. Internal fixations were carried out with plate and screw(5 cases), screw and wiring(4 cases), and wiring (3 cases). 5. The separation of symphysis pubis with minimal disruption of posterior stabilizer were treated by closed treatment or internal fixation of the separation of symphysis pubis diastasis alone, and its result was good or excellent. 6. We think that the symphysis pubis diastasis with severe disruption of posterior stabilizer should be fixed anteriorly and posteriorly both.

The Fracture of the tibia is the most common on fracture of the long bone and has high complication rates due to it's anatomical property. Segmental fractures are characterized by two or more fractures on different levels of the shaft with an intermediate segment. In addition to general characteristics of tibial fracture, segmental fractures are commonly combined with extensive soft tissue injury comminution and displacement with poor blood supply in it's intermediate segment. Recently, closed intramedullary nailing under the image intensifier has been widely used and its good results have been reported. The purpose of this study is to compart the bony union, functional result and complication between Ender nail and interlocking nail which we treated with intramedullary nailing in 20 segmental tibial fractures of 19 patients from 1990 to 1991. Minimum follow up period was 12 months. The results were as follows : 1. The most common type of fractures was Melis type Ⅰ. 2. All fractures were united and average union time was 24.9 weeks. 3. The major complications were delayed union (6 cases) joint stiffness (6 cases), superficial infection (3 cases), and angular deformity (2 cases). The complication rate in Ender nail was higher than Interlocking nail. 4. According to the criteria of functional results by Klemm and Borner. we obtained a 87.5% of excellent and good resulted in Ender nailing group and 91.7% of excellent and good results in Interlocking nail group.

진행성 골화성 섬유 이형성증은 2 백만명 중에 1명 발생하는 매우 드문 유전질환이다. 저자들은 2차례의 외상후 심해진 진행성 섬유 이형성증환자에서 최근 다시 발생된 외상후 생긴 병변부위에 biphosphonate와 steroid 투여로 최근수상부위의 근육 골화와 경화를 현저한 호전을 보였으나, 기존의 골화가 이미 진행된 병변에서는 잘 반응하지 않음을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Fibrodysplasia ossificans progressiva(FOP) is an extremely rare hereditary disorder characterised by progressive heterotopic ossification of the soft tissue. The resulting progressive immobilization of the limbs, jaw and chest wall generally leads to severe disability. We present an 20-rear-old man with advanced FOP. He had two operative interventions by prior traffic accident and recent biopsy. It resulted abnormal ossification. Treatment for this disorder is avoidance of exacerbating factors and medical strategies is biphosphonate and steroid. We observed the course of ossification and muscle atrophy during biphosphonate and steroid therapy in advanced FOP.

The purpose of this study was to investigate the effects of chung-seo-ik-gi -tang administration on the metabolic responses and hormones in 18 healthy-male elite boxes. All subjects were divided randomly with two groups, Chung-sea-ik-gi-tang Group(N=18) and placebo group(N=18) and perfored with 70% of HR max using bycicle ergometer unfil exhaustion. During the submaximal exercise, heart rate was maesured every two min. The blood samples were collected from antecubital vein by 10ml syranges(6ml/each) before immediately after exhaustion, recover-10 min, recover-20 min and recover-30 min. The samples were to analyzed for the level of glucose, lactate, TG, TC, HDL-C, insulin and catecholamine. The results of various blood parameters were summarized as follow; l. Energy substrates (plasma glucose, TG, TC, HDL-C) changes in group C were significantly different from group P. Plasma glucose in group C was significantly lowered at recover-10 min compared to group P (P<0.05). and also TG, TC and HDL-C in group C were significantly increased after 3 weeks compared to group P (P<0.05) whereas. Lactate accumulation in group C was significantly decreased after 3 weeks compared to group P (P<0.05). 2. Plasma insulin level was not showed significant difference between two groups. But insulin depression tendency after 3, 6 weeks in group C was allevated compared to group P. Increasing rate of norepinephrine in group C at Post-exhaustion after 3weeks lowered compared to group P. Norepinephrine in group C at rest periods after 3 weeks showed significant difference compared to group C. The results indicated that Chung-seo-ik-gi-tang had the effects of ergogenic aids on fatigue resistance and recovery from exhaustive exercise at the level of 70% HR max.
