  • A 13-year-old neutered female Maltese was referred to Veterinary Medical Teaching Hospital of Seoul National University with 8-month-history of gradually enlarging retrobulbar mass in the right eye. On the ophthalmic examinations, exophthalmos, exposure keratitis, and cataract were observed, and menace response was absent in the eye. The fellow eye was normal except for nuclear sclerosis. On the ocular ultrasonographic evaluation, a mass was identified in retrobulbar and periocular region in the right eye. Exenteration was performed in order to remove the mass. Histopathologic evaluation revealed that most part of the mass was composed of epithelial-like neoplastic cells. Invasion into adipose cells and osseous metaplasia around the mass were also confirmed. Based on the radiologic and histopathologic examination, the mass in the right eye was diagnosed as primary retrobulbar meningioma. Eleven months after the surgery, recurrence was not observed.

  • $Bi_2Sr_2CaCu_2O_x$(Bi-2212) and $Bi_2Sr_2Ca_2Cu_3O_y$(Bi-2223) high-Tc superconductors(HTS) have been manufactured by plasma spraying, partial melt process(PMP) and annealing treatment(AT). A Bi-2212/2223 HTS coating layer was synthesized through the peritectic reaction between a 0212 oxide coating layer and 2001 oxide coating layer by the PMP-AT process. The 2212 HTS layer consists of whiskers grown in the diffusion direction. The Bi-2223 phase and secondary phase in the Bi-2212 layer were observed. The secondary phase was distributed uniformly over the whole layer. As annealing time goes on, the Bi-2212 phase decreases with mis-orientation and irregular shape, but the Bi-2223 phase increases because a new Bi-2223 phase is formed inside the pre-existing Bi-2212 crystals, and because of the nucleation of a Bi-2223 phase at the edge of Bi-2212 crystals by diffusion of Ca and Cu-O bilayers. In this study the spray coated layer showed superconducting transitions with an onset Tc of about both 115 K, and 50 K. There were two steps. Step 1 at 115 K is due to the diamagnetism of the Bi-2223 phase and step 2 at 50 K is due to the diamagnetism of the Bi-2212 phase.

  • A corneal dermoid is a benign congenital mass usually affecting the lateral limbal region. A 3-month old male Shih Tzu dog with abnormal tissue on right cornea was referred to Veterinary Medical Teaching Hospital of Seoul National University. On ophthalmic examination, there was no evidence of visual impairment. Slit lamp biomicroscopy assessment revealed a mass, located in the inferior and temporal part of right cornea. The lesion was typically hemispheric and covered with pink skin. Superficial keratectomy was performed to remove the mass. On histopathological examination, the lesion was diagnosed as a corneal dermoid. Four months after operation, there had been no recurrence and hair regrowth.

  • 준강자성체 구리-철-크롬 산화물 $CuFe_{0.9}Cr_{1.1}O_4$을 제조하여 액체질소 온도에서부터 닐 온도까지의 범위에 대한 뫼스바우어 분광실험을 하였다. 닐 온도는 355 K로 측정되었으며, 닐 온도 이상에서의 전기사중극자 상호작용의 크기인 사중극자 분열값은 0.50 mm/s인 반면, 닐 온도 이하에서의 사중극자 이동값은 실험오차 범위 내에서 0.00 mm/s이었다. 이러한 전기사중극자 상호작용에 대한 겉보기 불일치 현상은 자기적 초미세 자기장이 전기장 기울기 텐서의 주축에 대하여 무작위로 배열된다는 모델을 이용하면 설명될 수 있다.

  • Polyurethane resin containing isocyanate is marked by excellent tensile and mechanical strengths and this test aims to gauge its applicability as a medical high polymer. Tris [2-(acryloyloxy)ethyl]isocyanurate and hexamethylenediisocyanate were added to a basic mixing ratio of HEMA (2-hydroxyethyl methacrylate), MMA (methyl methacrylate), NVP (n-vinyl-2-pyrrolidone) and crosslink agent, EGDMA (ethylene glycol dimethacrylate) with increasing proportions and copolymerized respectively. Also, the basic physical properties of the polymerized high polymers including refraction rate, tensile strength, light transmission and water content were measured to confirm that they are appropriate as hydrogelcontact lenses. After measuring the physical properties of high performance polymers produced by adding tris [2-(acryloyloxy) ethyl]isocyanurate, it was found that the average tensile strengths of sample TRIS1 to TRIS10 were between 0.285 and 0.612 kgf, while the average values of refractive index were ranged from 1.441 to 1.449 with water content from 30.00 to 37.35%.The measurement of physical properties of the copolymers generated by adding hexamethylenediisocyanate showed that the average tensile strength of sample HEXA1 to HEXA10 ranged from 0.267 to 1.742 kgf, the refractive index ranged from 1.443 to 1.475 and water contents were in the range of 21.22 to 35.58%. In all combinations the transmission rates satisfied the transmittance of general hydrogel contact lenses. From theresults, it is possible to conclude that the produced copolymers can be used as contact lens materials with excellent tensile strength.

  • 본 연구는 자동차 엔진의 구동을 각종 부대 장치로 전달하는데 사용되는 V-rib 벨트 재료의 내열성 및 내마모성을 향상시키기 위한 연구이다. 이를 위하여 고무 매트릭스는 EPDM과 CR, 그리고 충전제로 ZnO, 면 및 아라미드 섬유의 함량을 달리한 시편과 v-벨트를 만들어 내열성과 내마모성 그리고 기계적 성질을 조사하였다. CR 배합계에서 ZnO의 함량이 증가함에 따라 내마모성이 증가하였다. 또한 면섬유의 함량이 증가함에 따라 벨트상태에서 견딜 수 있는 구동시간은 증가하지만 내마모성은 감소하는 결과를 보였다. EPDM 배합계에서 면섬유의 충전한계는 30 phr정도였다. 또한 아라미드와 면섬유를 혼합 사용한 결과 구동시간과 내마모성을 동시에 증가시킬 수 있었으며, 그 단섬유의 최적 조성은 아라미드섬유/면섬유 비율이 1/5인 것으로 조사되었다. 동일한 면섬유 함량에서 EPDM 배합계 가 CR 배합계보다 우수한 물성을 보였다.
