복부 방사선 촬영은 몇몇 질환들에 대해서는 매우 신뢰도가 높은 검사중의 하나이며, 그 외에도 많은 증상들에 대한 스크린 검사로써 매우 유용하다. 그러나, 복강 내에는 여러 장기들이 있고, 환자의 준비나 상태에 따라 여러 변수들이 있어, 늘 판독에 최적한 상황에서만 판독하게 되지는 않는다. 여러 변수에 대처하여 가장 정확한 복부 방사선 판독을 할 수 있는 안목이 중요하다고 하겠다.

The ex utero intrapartum treatment (EXIT) is used for unborn fetuses in cases of predictable complications of postpartum airway obstruction. The delivered fetus is maintained on placental circulation while airway is established and this is carried out by a multidisciplinary team. Teratomas arising from the palate or pharynx may cause immediate life-threatening airway obstruction to the newborn. In our case, congenital oral teratoma was detected via prenatal ultrasound. The treating team determined that this may induce airway occlusion at birth and decided to perform an EXIT to secure an airway. On the day of birth, debulking of the tumor was performed and the fetus was successfully delivered. Vital signs were stable without intubation management.

In order to obtain higher efficiency and to reduce the amount of CO_2 exhausting from high temperature components, operating temperature and pressure have been raised recently. Such effort required the development of new high temperature materials, which have better high temperature properties. As the result, P92 steel is developed as a new high temperature piping material. In this study, the tensile properties and the fatigue crack growth rates of P92 steel were obtained at 600℃, 650℃ and 700℃ and the effects of temperature on high temperature characteristics were investigated using Base metal(As received), Base metal(As PWHT) and Weld metal.

Angiokeratoma is a rare, cutaneous disorder that typically manifests as multiple lesions and is often associated with a number of metabolic disorders. Although solitary cutaneous forms have been reported, localized lesions within the oral tongue have not been described so far. We report a 16-year-old male with a solitary pigmented lesion of his oral tongue tip. The lesion was a mixture of purple and white in color with a granulomatous appearance. Histopathological examination of the lesion obtained by excisional biopsy showed features consistent with angiokeratoma. We report a case of solitary angiokeratoma of the oral tongue tip and review the clinical and pathologic features of this unusual condition.
Clinical application of quantitative computed tomography in osteogenesis imperfecta-suspected cat

One-year-old male Persian cat presented with multiple fractures and no known traumatic history. Marked decrease of bone radiopacity and thin cortices of all long bones were identified on radiography. Tentative diagnosis was osteogenesis imperfecta, a congenital disorder characterized by fragile bone. To determine bone mineral density (BMD), quantitative computed tomography (QCT) was performed. The QCT results revealed a mean trabecular BMD of vertebral bodies of 149.9 ± 86.5 mg/cm3. After bisphosphonate therapy, BMD of the same site increased significantly (218.5 ± 117.1 mg/cm3, p < 0.05). QCT was a useful diagnostic tool to diagnose osteopenia and quantify response to medical treatment.
