被陰에 의한 光勾配實驗을 통하여 對照區와 相對照度 75,50,25% 處理區에서의 질경이(Plantago asiatica L.)의 生長狀態를 比較, 分析하였다. 相對照度가 높아질수록 植物體의 物質生産과 C/F ratio는 增加하였으나 T/R ratio는 減少하였다. 한편, 相對照度가 낮아질수록 뿌리와 花穗를 제외한 全 器官의 伸長成長이 增加되었고 水分含量 역시 높아지는 傾向이 있었으나, 花梗 및 잎의 數는 減少하였다. 乾物量에 의한 相對生長率은, 相對照度 75,50,25%區에서 對照區에 대해 각각 90,70,40%의 生長을 보여 照度低下에 따른 生長沮害를 觀察할 수 있었고, 花梗 및 花穗의 出現時期에 있어서는 相對照度가 가장 낮은 S₃區에서 다른 區에 비해 10日間의 差異로 늦어짐을 볼 수 있어 被陰이 질경이의 生長과 分布를 制限하는 要因의 하나임을 알 수 있었다. The light gradient of 100%, 75%, 50% and 25% in light intensity were established in order to investigate the difference of the growth of Plantago asiatica L. The amounts of matter production, water content, C/F ratio and numbers of leaf and scape tend to increase gradually with the increase of the relative light intensity. On the other hand, the elongations of all organs execpt root and spike and T/R ratio increase with the decrease of the relative light intensity. In the relative value of dry weight, the 75%, 50%, and 25% plots show the 90, 70 and 40% growth compared with the control group, respectively. Particulary, the emergence of spike and scape at 25% plot was delayed for 10 days compared with other plots. Judging from these results, shading is considered as a limiting factor in the growth and distribution of Plantago asiatica L.

However, even the most technically perfect anastomosis can neither eliminate the damage which microneedles cause on the vascular endothelium nor foreign body reaction to the suture material. Thrombosis developed at the suture site and regressed if the stimulus for the thrombosis is not severe. Partial thrombosis was inevitable after microvascular anastomosis. Since systemic thrombolytic drugs were used initially in the management of pulmonary emboli, urokinase were also used in prevention of thrombolysis and thrombolysis after microvascular anastomsis. This experimental study includes the effect of urokinase on the microvascular anastomosis in rabbits. The patency was observed, and platelet count, fibinogen, prothrombin time, and activated partial thromboplastim time were examined. In the case of thromboses, the anastomotic sites were resected and examined microscopically. The results were as follow; 1. The patency rate was increased 15 percent in experimental group than control group. 2. There were no differences in platelet count and the prothrombine time between experimental and control group. 3. The level of fibrinogen was decreased 157㎎/dl in experimental group less than control group. 4. The activated partial thromboplastin time was increased three to four times at postoperative period more than preoperative period in experimental group. 5. In light microscopic examination of thrombotic vessel wall revealed inflammatory reaction to suture material. In the experimental group, the thrombi were loose and defibrinated than control group.

The purpose of this study is to evaluate the distribution of stress in the root end resected teeth. The finite element method was used to compare stresses along the root and retrograde filling material in seven two-dimensional models of mandibular 2nd premolar. Each model was endodontic treatment and gold crown restoration. Each model divided with amagam corerestoration or gold casting post restoration. Thus each model divided with shape of root end resection, depth of retropreparation and exposure length of root in the bony cavity. The seven models were classified as in the table 1 below. ◁표참조▷ A load of 500N was applied 45°diagonally on the lingual slope of the buccal cusp. These models were analyzed with two dimensional finite element methods. The results of this study were as follows : 1. The maximum tensile stress along the inner canal wall was shown on the model 7. 2. When the model 1 was compared with the model 5, the maximum tensile stress along the inner canal wall showed the model 1. 3. Less equivalent stress was shown on the model 6 and more equivalent stress was shown on the model 4. 4. More shear stress was shown on the retrograde filling material of the model 7. 5. The models with increased length of exposed root in the bony cavity demonstrated a gradual increase to the tensile stress in X direction which occurred approximately a boundary between the bone and exposed root in the bony cavity. 6. The model which had a case of matching the apex of post and a boundary between the bone and exposed root in the bony cavity demonstrated more increase tensile stress in X direction than other models.

Objective : To report the clinical result of segmental pedicle screw fixation and translation technique in surgical correction of idiopathic scoliosis. Methods and materials : Ten idiopathic scoliosis. patients treated with segmental pedicle screw fixation and translation technique were analyzed retrospectively. The mean follow-up interval was 23.8months, with a minimum of 12 months. Eighteen structural curves were fused in one double curves(King type Ⅰ), seven double thoracic curve(King type Ⅴ) and two thoracolumbar curve. Deformity correction, apical vertebral rotation(AVR), apical vertebral translation(AVT), trunk balance, shoulder balance and complications were evaluated. Result : The structural curve was corrected from 47.4±10.6° to 20.3±5.9° at 1week after surgery and 55.6±14.1° at latest follow-up. AVR was corrected from 2.06±0.4 to 0.94±0.41 at 1week after surgery and latest follow-up. AVT was improved from 25±15.7㎜ to 11.5±7.3㎜ at 1week after surgery and 12.3±7.3㎜ at latest follow-up. There were no trunk imbalance(less than 10㎜ distance from C7 plumb line), no shoulder imbalance(less than 10㎜ shoulder height difference) and no screw related complications. Conclusions : The segmental pedicle screw fixation and translation technique is an effective method in treating for idiopathic scoliosis.

The double eyelid operation is one of the most common cosmetic surgery performed in orientals, and there are numerous studies about surgical procedures of that. In the case of appropriate candidates, the non-incision technique makes excellent cosmetic results, with the advantages of shorter operating time, less morbidity, less pain, no scarring and easy revision of shape. But, usually the non-incision technique is recommended in the cases with thin upper eyelid, small amount of orbital fat, less redundant skin of upper eyelid and in whom a wide fold is not desired so on. Therefore, the disadvantages of this method are that it cannot be applied to all patients. The postoperative complications are disappearance or faded fold, formation of cyst of lumps, asymmetry etc. and the incidence of these complications is slightly higher than those of the incisional method. In this study , the double eyelid operation using the continuous buried suture method was performed in 210 patients for formation of double eyelid from Jan. 1993 to Dec. 1995. In conclusion very good results can be obtained by the continuous buried suture method even in the cases of puffy upper eyelid. This method can make a double eyelid shape in the fashion the patient wants and can be a new indication for correction of unilateral double eyelid. This method is safe, satisfactory and take shorter postoperative recovery time and it can reduce the incidence of postoperative complications.

We consider a facility layout problem for optimized material flow system design in the automated production system design. Existing facility layout algorithm have a weak point that arranged facilities have irregular shape or don't preserve their own shape and size. The proposed algorithm give a layout which is minimize total material handling cost and maximize space utility under preserving each facilities own shape and size.
