  • We report two cases of spinal subdural hematoma in the lumbar region after trauma. They developed in a 27-years old man and a 32-year-old woman. They had no other causes such as bleeding tendency, preexisting spinal lesions, lumbar puncture, vascular malformation and anticoagulant therapy. There lesions were diagnosed with MRI(fat suppression) and treated by lumbar puncture.

  • This study investigated influence of kind of fine aggregate on fundamental properties of concrete. For the properties of fluidity with various type of fine aggregate, lime stone crushed fine aggregate(Ls) exhibited favorable result, due to grain shape and particle distribution, and next was granite crushed fine aggregate(Gs), natural fine aggregate(Ns). Ns had the highest value of air content while Ls had the lowest, due to the effective filling performance by continuos particle distribution. Ls, Ns, Gs in an order had higher bleeding capacity and faster setting time. However, compressive and tensile strength value exhibited similar tendency, regardless of aggregate type.

  • Hemophilia is a hereditary condition in which one of the normal blood clotting factors is absent. This sex-linked, recessive disease, transmitted by the female and expressed in some of her male offspring, is characterized by significantly delayed coagulation times and by the tendency to hemorrhage. On the dental treatment especially, surgical procedure, appropriate methods of hemorrhage control are required. These methods are replacement therapy, antifibrinolytic agents, and local hemostatic methods. In this case, we successfully extract residual roots of hemophiliac patient without eccessive post operative bleeding using replacement therapy and surgical splint.

  • This paper investigates the relationship between the compression ratio and the gamut area for a reconstructed image when using JPEG and JPEG2000. Eighteen color samples from the Macbeth ColorChecker are initially used to analyze the relationship between the compression ratio and the color bleeding phenomenon, i.e. the hue and chroma shifts in the a*b* color plane. In addition, twelve natural color images, divided into two groups depending on four color attributes, are also used to investigate the relationship between the compression ratio and the variation in the gamut area. For each image group, the gamut area for the reconstructed image shows an overall tendency to increase when increasing the compression ratio, similar to the experimental results with the Macbeth ColorChecker samples. However, with a high compression ratio, the gamut area decreases due to the mixture of adjacent colors, resulting in more grey.

  • Waste foundry sand of industrial waste which is happening by vast quantity according to fast development of industry has much the occurrence amount and processing method is depended on reclamation, and is using by fine aggregate for construction by recycling method among others. In this research Waste foundry sand powder into cement replace fare use possibility availability judge wish to Slump and air content decreased the replacement ratio increases by concrete special quality that do not harden according to experiment result, and unit capacity mass and bleeding increased the replacement ratio increases. Hardening concrete intensity special quality displayed strength improvement to replacement ratio 20%, and tendency that watertightness increases most in replacement ratio loft in watertight property appear. Considering the strength and watertight properties, the adequate usage of waste foundry sand powder is the 10% of replacement ratio.

  • This study is about physical properties of concrete with changing displacement ratio of calcium sulfa aluminates(CSA) type admixture. Firstly, test shows that as displacement ratio of CSA increases and setting properties changes, fluidity and air contents decreases. In water to binder ratio 35$\%$ and 45$\%$, concrete using the cement replacing CSA 4$\%$ by volume shows that bleeding decreases 94.7$\%$ and 74.3$\%$ respectively, compared with plain concrete. In addition, setting time was promoted around 3 to 6 hour and 1 to 4 hour respectively. For harden concrete, increase of displacement ratio caused tendency of higher compressive strength as OPC has at early age. Replacing higher CSA admixture led to reduce of drying shrinkage.

  • The treatment of intraosseous ateriovenous malformation in the jaw is difficult because of life threatening frequent bleeding tendency. The surgical resection of AVM may be mortal due to massive blood loss. In the growing pediatric patient, surgery may cause facial deformity and growth disturbance. So currently, the treatment of AVM is only embolization using various material through endovascular access, direct-puncture or embolization in conjunction with surgical resection. We report a case of combined techniques.

  • The purpose of this study was to evaluate the effect of the lateral displacement on the mandibular condylar growth in the rabbit. The experimental animals were twenty White NewZealand rabbits of 4-week old. Ten of them was used as control group, and experimental animal was composed of remaining ten. Laterodeviation appliance was made of cast base metal and appliance was cemented with resin in permanent fashion. Experimental group were sacrificed at 1, 2, 4, 6, 8 weeks form beginning of the experiment. Both of temporomandibular joint were prepared for histologic study. The conclusions are: 1. In control group, there was slight increase of proliferative zone and hypertrophic zone at 2-week control animal and slight reduction at 4-week. 6-week and 8-week control animal were similiar to 1-week control animal. 2. In right mandibular condyle of experimental group, 2-week experimental animal showed marked increase of proliferative zone and hypertrophic zone at posterior surface of condylar head. In 8-week experimental animal marked increase at anterior surface of anticular surface is observed. 3. In left mandibular condyle of experimental group, proliferative zone and hypertrophic zone were reduced at 1-week experimental animal and slight increase at 2-week. Proliferative zone and hypertrophic zone were reduced at 4-week experimental animal and were slightly increased at 6 week. 4. After 8 weeks, right and left condyle were not different in experimental group. The condylar cartilage was stabilized 8 weeks after the experiment. No marked traumatic change was seen, but minute focal bleeding was seen at articular cavity in 1-week, 2-week and 4-week experimental animal. 6-week and 8-week experimental animal did not show bleeding tendency in articular cavity.

  • Objective : Hemophilia, a genetically determined disorder, is characterized by abnormality of the coagulation mechanism due to functional deficiency of a specific factor, namely VIII or IX. In this study, the effect of Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was evaluated. Methods : We treated him with acupuncture by stimulating Dong-Si acupuncture point(Yuk Wan) and assessed the effect by using manual dynamic evaluation of MRC(Medical Research Council) and Modified Barthel Index. Results : After treatment, the bleeding tendency was grossly reduced and bleeding lesion was absorbed gradually. And manual dynamic evaluation of the upper extremity increased from 4 grade to 5 grade. Conclusions : This result suggest that Dong-Si acupuncture therapy on the cerebral hemorrhage patient with hemophilia was effective. And futher studies are required to concretely prove the effectiveness of Dong-Si acupuncture therapy for treating hemorrhagic diseases.
