N/A Objectives: Thallium-201 test per rectum (Shunt Index) and ICG-Rmax have been used for the evaluation of portosystemic shunt and functional reserve of the liver. The mean values of Shunt Index and ICG-Rmax have not been determined in HBsAg healthy carriers confirmed by liver biopsy. In this stud)', the mean values and correlation between Shunt Index, ICG-I4max and ICG- B15 in these subjects were estimated, and the progression from HHsAg healthy carrier to chronic liver disease was observed prospectively. Methods: Twenty-four HHsAg healthy carriers (male 15 and female 9) were analyzed from 1988 to 1993. The mean duration of follow-up is 17months(range : 2~59). All subjects were diagnosed by liver biopsy. Shunt Index, ICCi-Rmax and ICG-l415 were obtained for each subject 3times weekly. Results: Vive from 24subjects(20.8%) were disclosed chronic persistent hepatitis associated with HHsAg during follow-up period. The mean values of Shunt Index. ICCi-Iimax and ICG-R15 were 0.24±0.07, 4.15±2.21mg/kg/min, and 7.85±3.00% respectively, in seventeen cases whose conventional laboratory data were continuously nor- mal. Shunt Index was well correlated (R-square= 0.34, p<0.0:) with 1.ICG-Rmax. Hut, ICG-Il15 was not correlated with both ICCi-Rmax and Shunt Index. Conclusion: One fifth of the biopsy proven HHsAg healthy carriers progressed to chronic persistent hepatitis associated with HBsAg. We suggest that laboratory follow-up for regular interval is necessary even in HHsAg healthy carriers. The mean values of Shunt Index and ICG-Rmax may be useful in the diagnosis of the chronic liver disease and assessment of outcome of the treatment.

Interruption system with the transformer type superconducting fault current limiter(TSFCL) is proposed in this paper. The interruption system with a TSFCL is a technology that it maximizes the interruption function of a mechanical DC circuit breaker using a transformer and a superconducting fault current limiter. By a TSFCL, the system limits the fault current till the breakable current range in the fault state. Therefore, the fault current could be cut off by a mechanical DC circuit breaker. The Interruption system with a TSFCL were designed using PSCAD/EMTDC. In addition, the Interruption system with a TSFCL was applied to the DC test circuit to analyze characteristics of a current-limiting and a interruption operation. The simulation results showed that the Interruption system with a TSFCL interrupted the fault current in a stable when a fault occurred. Also, The current-limiting rate of the Interruption system with a TSFCL was approximately 69.55%, and the interruption time was less than 8 ㎳.
