  • We continue the study of power-Armendariz rings over IFP rings, introducing $k$-power Armendariz rings as a generalization of power-Armendariz rings. Han et al. showed that IFP rings are 1-power Armendariz. We prove that IFP rings are 2-power Armendariz. We moreover study a relationship between IFP rings and $k$-power Armendariz rings under a condition related to nilpotency of coefficients.

  • This report is about wireless energy transform system. It means something to charge without a line of contact. Existing charging has been many defect, including badness of the line, limitation of the space and the time and so on But this is one of the way that can complement it. So our goal is making the wireless charger that is effective and easy to use.

  • Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by profuse jelatinous materials in the abdominal cavity and pelvis with mucinous implants on the peritoneal surface. There are some studies for serum tumor markers, including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 125 (CA125), to assess the risk of recurrence following cytoreductive surgery and intraperitoneal chemotherapy. However, rare cases were reported about recurrence with increasing serum CEA levels. Herein, we report a case of recurrence of PMP according to serially elevated serum CEA.
