저자들은 신체 여러 부위에 기형을 동반한 선천성 사지결손증 2예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Congenital skeletal limb deficiencies are rare cases in congenital anomalies of newborn infants. Authors experienced two cases of peromelia, who had multiple anomalies such as absence of external genitalia, anal atresia, hemivertebrae, anencephaly and cephalocele. In case 1, autopsy findimgs revealed the complete duodenal obstruction between second and third portion, and anal atresia. X-ray findings showed multiple bone anomalies such as hemivertebrae, dislocation of femoral head due to incomplete formation of the pelvis. In this case, we could not recognize sex of the baby grossly so we confirmed that is male by chromosomal study and pathologic findings. In the second case, we could observed that the baby was anencephalic monster with cephslocele, but other organs were normal in autopsy findings except multiple skeletal limb deficiencies.

저자들은 1975년 2월 가톨릭의과대학 부속 성모자애병원에서 수술후 병리학적으로 확진된 원발성 난관암을 치료하였기에 문헌고찰과 함께 보고한다. Primary carcinoma of the fallopian tube is the rarest tumor of the female reproductive organs. We expenienced a patient of primary carcinoma of the fallopian tube who was admitted to our Ob. & Gy. Dept. under the impression of the ovarian tumor. After laparotomy, we confirmed pathologically egg-sized primary carcinoma on the right fallopian tube. We present this tumor with brief review of literatures.

This study presents a novel monitoring technique for underwater high-voltage direct current (HVDC) cables based on the Distributed Acoustic Sensor (DAS). The proposed technique utilizes vibration and acoustic signals generated on HVDC cables to monitor their condition and detect events such as earthquakes, shipments, tidal currents, and construction activities. To implement the monitoring system, a DAS based on phase-sensitive optical time-domain reflectometry (Φ-OTDR) system was designed, fabricated, and validated for performance. For the HVDC cable monitoring experiments, a testbed was constructed on land, mimicking the cable burial method and protective equipment used underwater. Defined various scenarios that could cause cable damage and conducted experiments accordingly. The developed DAS system achieved a maximum measurement distance of 50 km, a distance measurement interval of 2 m, and a measurement repetition rate of 1 kHz. Extensive experiments conducted on HVDC cables and protective facilities demonstrated the practical potential of the DAS system for monitoring underwater and underground areas.
