유기금속분해법(MOD, Metal Organic Decomposition)에 의하여 ITO 박막을 제조하고 SnO$_2$의 조성과 소성온도의 변화에 따른 박막의 특성변화를 고찰하였다. SnO$_2$의 양이 변하여도 ITO는 In$_2$O$_3$의 결정구조를 유지하고 있었으며, 이로부터 Sn이 In자리를 치환하여 고용체를 형성함을 알 수 있었다. SnO$_2$를 9wt.% 첨가 하였을때 비저항이 2.5$\times$$10^{-3}$$\Omega$-cm로 가장 낮은 값을 보였으며, 이는 타 연구자들의 결과치 보다 약 10배정도 큰 값이다. 이러한 비저항값의 차이는 작은 입경으로 인한 이동도의 감소 때문인 것으로 판단되었다. 투광도는 SnO$_2$의 첨가량 및 소성온도에 크게 의존하지 않았으며 가시영역에서 90% 이상을 보였다. 광흡수단으로부터 계산된 optical energy gap은 4.51-4.96eV 이었다. Thin films of Indium tin oxie (ITO) were prepared by the process of metal organic decomposition. Light transmittance and electrical transport properties of the films were studied with varying the firing temperature and SnO$_2$content. XRD study showed that tin substituted indium in the In$_2$O$_3$lattice. The resistivity had the minimum value of 2.5 ${\times}$ 10$\^$-3/$\Omega$-cm when the content of SnO$_2$was 9wt.%. This value was higher by a factor of 10 than the previously reported results. This difference was attributed to the low mobilities presumably caused by the fine grain size. The transmittance of ITO films in the visible range was over 90%, and the optical energy gap calculated from the absorption edge was in the range of 4.51 and 4.96eV.

We report a case of huge ovarian cyst, which we met very rarely today, although a good many reports were found in the past literature. A 23 - year - old multiparous woman was admitted to the Chosun University hospital on Jan 1, 1991, complaining of the distension of the abdomen and inability to walk. Her height was 153 cm, body weight 60 kg and abdominal circumference was 91 cm on admission. The tumor was removed surgically after puncture aspiration of cystic contents. It proved that it had originated from It. ovary. The tumor weighed 13 kg and the volume of cystic contents was 6.5 L. Pathologic diagnosis was serum cyst adenocarcinoma, It. ovary. Hospital course had been uneventful and the patient was discharged on the post-op 7th day.
