Defects of oral cavity occur in the course of treatment by surgery of cancer in the head and neck. More often they are the results of surgery after previous operation and irradiation already have been tried in an attempts to eradicate the primary cancer. The methods for repairing the oral cavity are variable and vary depending upon exisiting conditions and individual preference. Familiarity with the different techniques is necessary so that one suitable for the problem may be selected. Several methods of repair are known which utilize flaps designed from the forehead, the neck and deltopectoral area, but reconstruction with these flaps often fails because of the poor vascular supply due to previos surgery and irradiation in this area. So it is necessary to select the flap which not only have more abundant vascular supply but also serve to nourish the scarred bed, damaged by irradiation, that is implanted, Myocutaneous flaps have the advantage of transffering well vascularized tissue for reconstruction. Moreover, the free flap transfer has not yet proven to be thoughtly reliable, if it is indicated in selected cases, it may be a better reconstruction for the repair of the oral cavity. In this papers, we demonstrate the versality and different kinds of the methods which were used by describing experineces of 8 flaps, 7 myocutaneous flaps and 1 free flap.

It is difficult to analyze the behavior of the geogrid reinforced soil walls, because most of the design methods for the reinforced soil structures with geogrids are based on the theory of the rigid-plasticity which takes no account of displacement and deformation of reinforcing material in the soil. In this study, the finite element analyses of geogrid reinforced retaining walls are performed to suggest an useful design method which consider the displacement and deformation of reinforcing material in the soil. The reinforcing effects on geogrid reinforced retaining wall are related with the length and interval of reinforcing materials. So the effects are analyzed with four different interval of reinforcing materials. It can be concluded from the results of analyses that the wall displacement, the earth pressure on the wall, the vertical stress distribution in the foundation and the settlement of backfill surface are decreased in direct proportion to the decrease of the interval.

국부의치용 금속인 Ni-Cr alloy와 Co-Cr alloy의 주조후 냉각방법에 따른 표면조직과 경도의 비교 연구

The purpose of this study was to investigate the relationship between the micro-structure and hardness of Ni-Cr alloy(Talladium™ alloy) and Co-Cr alloy(Wironium^(?) extra-hard alloy), which are widely used as partial denture frame work these days, depending on the cooling method, followed by casting. The frist group was bench cooled at room temperature(20℃), the second group was slowly cooled in the furnace from 700t to room temperature, and third, rapidly cooled in 20~22℃ water. The micro-structures of each specimen were compared by means of photomicrograph taken by metallurgical microscope. In addition to the physical characteristics of each specimen were obtained using the Rockwell C Scale. The results were obtained as follows: 1) The hardness value of Talladium™ alloy appeared higher than the Wironium^(?) alloy. 2) The hardness value of the slow cooling method(in the furnace) appeared higher the than the bench cooling method, water cooling method. 3) The grain particle in the slowly cooled alloy were much finer than the bench cooling method, water cooling method. 4) In the cooling method of Talladium™ alloy and Wironium^(?) alloy for partial denture the slow cooling method was considered more profitable than the bench cooling method, water cooling method.

This paper achieves a research about avoidance of obstacles avoidance based on ultrasonic sensor. The performance of the proposed obstacle avoidance robot controller in order to determine the exact dynamic systems modeling system that uncertainty is difficult for nomadic controlled robot direction angle by ultrasonic sensors throughout controlled performance tests. In additionally, this study is an in different ways than the self-driving simulator in the development of ultrasonic sensors and unmanned remote control techniques used by the self-driving robot controlled driving through an unmanned remote controlled unmanned realize the performance of factory automation.

Crushed Stone Pile(CSP) is suitable for improving soft silts and clays and loose silty sands. The effects of this method are increasing bearing capacity and slope stability, reducing settlement, increasing the time-rate of consolidation, and reducing liquefaction potential. In this study several model tests are carried out to investigate the bearing capacity of CSP treated ground. The results show that bearing capacity increases with the area replacement ratio and the preconsolidation pressure of the ground.

Drainage planning model was developed to examine the capability of flood drawdown in existing detention facilities and also to plan drainage system. This model is composed of inflow, storage, and outflow com-ponents. SCS unit hydrograph is used to generate inflow. Stage-volume relationship is used to analyze the capacity of storage. Outflow is depen-dent of the storage of canal, the rate of pumping, and the geometry of outlet control structures. Modeling is based on trial and error method that computation continues until simulation outputs approach the capacity of storage of detention facilities. Model developed was applied to Jemin stream basin of 7.6㎢ in Gongju city. Jemin stream is confluent to Keum river and have a backwater phenomenon in time of flood in Keum river. Peak flow of Jemin stream on 100 year design rainfall was 154㎥/s from SCS hydrograph. Pumping capacity was 57.9㎥/s and detention basin capa-city was 475.000㎥ from tangent line method that cumulative storage line in tangent to the rate of pumping. Using this drainage model, pumping capacity was 105‰/s with canal closed because the place of constructing the detention basin around Jemin stream is insufficient. But, the analysis of backwater based on standard step method showed that Jemin stream was not overflowed in time of Keum river's flooding. Therefore, it is diagonosed that the present stage of drainage system in Je-min stream is able to drain off 100 year design inflow.

Giant cell variant of hepatocellular carcinoma is well recognized?. However, it is sufficiently rare to warrant reporting, especially when this malignant tumor invade and metastasize extensively. According to Peters?, about 14% of hepatocellular carcinoma contain giant cells, but one composed mostly of giant cells must designated as giant cell variant. We experienced an autopsy case of giant cell variant of hepatocellular carcinoma composed mostly of pleomorphic malignant giant cells, with diffuse invasion of abdominal organs and metastasis to the mesentery and transverse colon.

For the purpose of studying the properties of calcium pump, the effect of methy lation on the ATP-induced Ca-transport in the isolated porcine sarcolemmal vesicles which were loaded with high KCI was investigated. 1) Ca-transport by ATP was increased significantly, compared to control sarcolemmal vesicles. 2) Ca-transport of the vesicles preincubated in the methylation medium without PM II was increased by ATP, but less than control sarcolemmal vesicles. 3) Ca-transport of the vesicles preincubated in the methylation medium with PM II was decreased by ATP in the KCl medium, but increased in NaCI medium. But Ca-transport by ATP in the methylated vesicles in the reaction medium (NaCI and KC1) was significantly decreased, compared with Ca-transport by ATP in the nonmethylated vesicles. From the above results, it was suggested that methylation of membrane protein by PM II can change the membrane properties or the activity of calcium ATPase transporting calcium.
