Background/Aims: The Japan Gastroenterological Endoscopy Society (JGES) has published guidelines for gastroenterologicalendoscopy in patients undergoing antithrombotic treatment. These guidelines classify endoscopic ultrasound-guided biliary drainage(EUS-BD) as a high-risk procedure. Nevertheless, the bleeding risk of EUS-BD in patients undergoing antithrombotic therapy isuncertain. Therefore, this study aimed to assess the bleeding risk in patients undergoing antithrombotic therapy. Methods: This single-center retrospective study included 220 consecutive patients who underwent EUS-BD between January 2013and December 2018. We managed the withdrawal and continuation of antithrombotic agents according to the JGES guidelines. Wecompared the bleeding event rates among patients who received and those who did not receive antithrombotic agents. Results: A total of 18 patients (8.1 %) received antithrombotic agents and 202 patients (91.8 %) did not. Three patients experiencedbleeding events, with an overall bleeding event rate of 1.3% (3/220): one patient was in the antithrombotic group (5.5%) and twopatients were in the non-antithrombotic group (0.9%) (p=0.10). All cases were moderate. The sole thromboembolic event (0.4%) wasa cerebral infarction in a patient in the non-antithrombotic group. Conclusions: The rate of EUS-BD-related bleeding events was low. Even in patients receiving antithrombotic therapy, the bleedingevent rates were not significantly different from those in patients not receiving antithrombotic therapy.

Summary of Event Bacterial, mycotic peritonitis and Candida fungemia developed in a patient with moderate ascites who had undergone endoscopic ultrasound-guided biliary drainage (EUS-BD). Antibiotics and antifungal agent were administered and ascites drainage was performed. Although the infection improved, the patient’s general condition gradually deteriorated due to aggravation of the primary cancer and he died. Teaching Point This is the first report to describe infectious peritonitis after EUS-BD. Ascites carries the potential risk of severe complications. As such, in patients with ascites, endoscopic retrograde cholangiopancreatography (ERCP) is typically preferred over EUS-BD or percutaneous drainage to prevent bile leakage. However, ERCP may not be possible in some patients with tumor invasion of the duodenum or with surgically altered anatomy. Thus, in patients with ascites who require EUS-BD, we recommend inserting the drainage tube percutaneously and draining the ascites before and after the intervention in order to prevent severe infection.

APPLICATION OF GIANT MAGNETOSTRICTIVE MATERIAL TO DISC BRAKE ACTUATOR
Yutaka OGAWA,Yukio MURATA,kazuo KAWASE,Hiroyuki WAKIWAKA,Tsutomu MIZUNO,Hajime YAMADA 전력전자학회 1998 ICPE(ISPE)논문집 Vol.- No.-
For the next generation railway brake system, a disc brake which can be operated directly and electrically is strongly expected. This paper deals with newly developed disc brake actuator using giant magnetostnctive materials (GMM) which can be integrated with disc brake Regarding the brake system performance, a better delay time was also attained which will contribute to shorten a stopping distance.<br/>
