  • Temporomandibular joint(TMJ) and dental occlusion are important in functional aspect as well as in cosmetic aspect for craniofacial surgery such as orthognathic and traumatic surgery. During these operations, appropriate maxillomandibular fixation(MMF) is especially necessary to conserve or reconstruct, dynamic TMJ and functional occlusion. Arch bar is one of the most popular method to gain proper MMF. Seventeen patients including 5 patients with mandibular fracture, 12 patients with orthognathic surgery(6 patients had relatively normal occlusion, however 6 patients had facial anomalies such as hemifacial microsomia with irregular occlusal plane.) were joined in this study. Arch bar was contoured on the dental cast, which was prepared for model surgery, prior to apply it on the facial anomaly patient. On using pre-contoured arch bar, patients felt better during the procedure and surgeons saved time. Moreover, well-contoured arch bar promises precise transmission of force on the bone, which implies surgeons do not need to worry about the occlusion while fixing bony structures. Authors suggest how to apply arch bar to satisfy basic theories about dental row and occlusion based on the experience. In addition, it is proposed to contour arch bar on the dental impression prior to apply it on the patient who has irregular and complex occlusal plane.

  • A taxonomic study of Viola section Chamaemelanium in Korea, based on morphological characters, was conducted with light microscopy and scanning electron microscopy. Two species, V. orientalis W. Becker and V. brevistipulata (Fr. et Sav.) W. Becker, are recognized by rhizome and cauline habits, trichomes on the ovary and the shape and beards of stigmas. The latter can be split further into three varieties, var. brevistipulata, var. minor Nakai and var. laciniata (Boiss.) W. Becker, according to the leaf morphology in particular. Viola brevistipulata var. laciniata has the most tooth number, and its teeth are irregular erose but the other two varieties are regular sinuate or serrate. As for the size of leaves, V. brevistipular var. brevistipulata is the largest but V. brevistipulata var. minor is the smallest among the varities. Of them, V. brevistipulata var. laciniata is newly recorded in Korea. It was also revealed that both development and arrangement of the beards developed on the ovary and stigma were particularly diagnostic in the identification of the Viola section Chamaemelanium species.

  • Bacterial meningitis is a rare complication of epidural block. As epidural abscess, subarachnoid infection associated with epidural catheters are related to the treatment of pain in diabetic patient whose immune responses have been impaired. A 51-year-old male with non-insulin dependent diabetes came to the pain clinic with neuropathic gain on right thigh and amputated stump of right leg. Treatment consisted of continuous epidural block and subcutaneous tunnelling and epidural morphine with bupivacaine was given on an outpatient basis. Two months later, the patient noted a diffuse frontal headache, projectile vomiting and stiffness neck. These symptoms became more aggrevated over the following 24 h and temperature went up to $38.4^{\circ}C$. A diagnostic lumbar puncture revealed CSF total protein of 747 mg/dl, glucose of 43 mg/dl, and $4320\;WBC/mm^3$. Cultures of epidural catheter tip grew hemolytic staphylococcus epidermidis. A chest x-ray and brain CT scan were negative. Antibiotic therapy with penicillin G and chloramphenicol was given for 15 days. Recovery was uneventful.

  • The patient was a 42-year-old female with breast cancer who had an implantable central venous catheter inserted percutaneously into left subclavian vein for chemotherapy. The postinsertion chest x ray revealed that there was no compressive sigh of catheter. Three months after insertion of the catheter, the patient was admitted to the hospital for 4th chemotherapy. The port was accessed but blood could not be aspirated and the catheter could not be flushed. A chest x ray revealed that the catheter was completely transected at the point where the catheter passed under the clavicle. Percutaneous removal of the distal fragment of the catheter was accomplished. The patient was discharged after successful removal of fragment of catheter.

  • This study aims to suggest the PV lightshelf and to evaluate the power performance of the photovoltaic systems easily mounted on the windows. For the study, the suggested systems consist of two parts as fixed and movable PV modules. Also, tempered glass and polycarbonate are used on the surface protection materials for solar cells of PV lightshelf. By using polycarbonate, the weight of PV lightshelf is lighter about 20%. The field tests are performed for five days by using real size models. The voltage, current and electric powers are measured as basic performances of PV lightshelf. Also, the irradiation, brightness and module surface temperature are measured as outside conditions. As results, the power performance of tempered glass PV lightshelf shows about 11(%) higher thant that of polycarbonate PV lightshelf. And the power performance shows about 5(%) higher in a horizontal system. This results could be used to develop the effective PV lightshelf in next study.

  • The cases of continuous epidural catheterization for pain control have increased nowadays. Epidural abscess, one of the complications of continuous epidural catheterization. can cause severe and permanent neurologic deficit. Though the incidence of epidural abscess is rare, we should devote every effort to prevention of abscess formation. And in the occurrence of epidural abscess formation, treatment should be started as early as possible with antibiotic therapy and surgical drainage to prevent permanent neurologic deficit. We experienced a case of epidural abscess following continuous epidural catheterization, and so the case is presented.

  • Paracalanus parvus and P. indicus collected in Korean coastal waters were redescribed to clarify taxonomical confusion. They showed the significant morphological difference in the $2nd\~4th$ swimming legs. In P. parvus the outer distal edge of 3rd segment of exopod of $2nd\~4th$ swimming legs is not serrated. The 1st basipodite has no spinules on the surface. In P. indicus the outer distal edge of 3rd segment of exopod of End and 3rd swimming legs is serrated, while that of the 4th swimming leg is not. This species has the 1st basipodite with a lot of spinules on the surface.
