In this paper the development of new technique based on the travelling-wave information contained in the post fault voltage and current signals has been presented. To develop fault location methods which can cope with close-up fault and zero-inception angle problems, magnitude of the backward wave has been used. The technique developed can be incorporated in a generalized algorithm for application as a high speed distance scheme. In this way some of the problems and limitations associated with travelling wave schemes are avoided. Verification of the relay operating principles is presented through digital computer numerical simulation using an electromagnetic transient program(EMTP) in conjunction with simulation of the proposed algorithms.

To evaluate the diagnostic significance of p16 overexpression in human hepatocellular carcinoma (HCC), we analyzed p16 status and growth inhibitory patterns by p16 overexpression in HCC cell lines having different pRE status. SKHep1 and SNU449 cells show homozygous deletion of p16. The p16 gene in SNU398 cell is inactivated at posttranscription level. Adenovira1-p16 (Ad-p16) infection inhibits the cell growth in Hep3B, SNU398, and SNU449. Failure of growth inhibition in SKHepl results from the low transduction efficiency of adenovirus. The p16-mediated growth inhibition shows G 1 phase arrest in pRE-positive SNU449 but not in pRE-negative Hep3B. These results suggest that therapeutic efficacy of p16 gene might be considered on the transduction efficiency and the toxicity of adenoviral vector. Beside, growth inhibitory effect of p16 could be exerted through either pRE-dependent or -independent pathway.

Transradial access is a widely accepted method for percutaneous coronary diagnostic and interventional procedures, and it has dramatically reduced access site vascular complications compared to transfemoral access. Arteriovenous fistula formation at the access site is an especially rare complication in transradial access. We report an extremely rare case of delayed radial arteriovenous fistula that developed one year after transradial coronary angiography, which was successfully treated by surgical repair.

Recurrent ventricular arrhythmia can be fatal and cause serious complications, particularly when it is caused immediately after an operation. Incorrect placement of a Swan-Ganz catheter can trigger life-threatening ventricular arrhythmia, but even intensive care specialists tend to miss this fact. Here, we report a case of recurrent ventricular arrhythmia causing a severe hemodynamic compromise; the arrhythmia was induced by a severely angulated Swan-Ganz catheter. The recurrent ventricular arrhythmia was not controlled by any measures including repositioning of the catheter, until the complete removal of the Swan-Ganz catheter. It is necessary to keep in mind that the position of the pulmonary artery catheter should be promptly checked if there is intractable recurrent ventricular arrhythmia.
