We report a case of a 54-year-old female with papillary fibroelastoma of the aortic valve who presented with ST-elevation myocardial infarction and cardiac arrest. Though her initial symptom was only atypical chest pain, life-threatening complications such as acute myocardial infarction and cardiac arrest developed. After cardiopulmonary resuscitation, we(More)
Mutations in KCNJ11 are a common cause of permanent neonatal diabetes mellitus. Previously, all patients carrying an R201H mutation in the KCNJ11 gene showed successful switches from insulin to sulfonylurea. Here, we report an unsuccessful switch in an 18-year-old patient carrying the common R201H mutation in the KCNJ11 gene.
In this paper a new switch architecture with quasi shared bu ering is proposed for a scalable multi cast ATM switch system The proposed switch shares a small size of dedicated bu ers for its input and out put ports and incoming cells are e ectively distributed within the switch system For sharing dedicated bu ers a distributor is proposed to evenly(More)
In this paper, a new cell re-sequence mechanism is proposed to restore cell sequence in multipath ATM switches. Since the proposed mechanism uses per-VC logical queues which store only the cells belonging to the same VC, the mechanism can reduce processing time compared to convent ional re-sequence mechanisms. The mechanism also has no limitation on the(More)
A B-ISDN national project in Korea has been carried out to develop a National Information Superhighway since 1992. An ATM switching system has been developed as one of the most important parts in the project, and has been tested in the National Information Superhighway testbed. In this paper, we develop a cell-level/call-level ATM switch simulator using(More)
