  • Backflow Prevention Mechanism of laparoscopic Toupet fundoplication using high-resolution manometry
    Surgical Endoscopy, 2016
    Co-Authors: Masato Hoshino, Nobuo Omura, Fumiaki Yano, Kazuto Tsuboi, Se Ryung Yamamoto, Shunsuke Akimoto, Hideyuki Kashiwagi, Katsuhiko Yanaga
    Abstract:

    Background The use of multichannel intraluminal impedance pH (MII-pH) and high-resolution manometry (HRM), which are new devices used to examine the esophageal function, has recently become common in Europe and the USA, thus garnering much attention. There have not been enough studies as of yet, however, on the esophageal motor function and the benefits of treatment after these devices have been used in laparoscopic fundoplication. Objective To use MII-pH and HRM to study the treatment effectiveness of laparoscopic fundoplication and consider a backflow Prevention Mechanism for laparoscopic Toupet fundoplication. Materials and methods The study looked at 27 of a total of 60 patients undergoing laparoscopic fundoplication due to reasons of either gastroesophageal reflux disease or esophageal hiatal hernia between October 2012 and February 2014, who underwent a postsurgical HRM examination. Of these, 25 patients whose symptoms disappeared following surgery and who were not orally administered gastric secretion inhibitor (of whom nine were male, average age 55.9 ± 14.9 years, and of whom 76 % underwent MII-pH) were taken as the subjects of the study. The postsurgical evaluation was conducted 3 months after the operation. Results Using HRM, although no change was noted in the lower esophageal sphincter pressure (LESP) ( p  = 0.943), an increase in lower esophageal sphincter pressure integral ( p  = 0.024) and extensions in both overall length and abdominal length were noted (both p

  • GLOBECOM - Green firewall: An energy-efficient intrusion Prevention Mechanism in wireless sensor network
    2012 IEEE Global Communications Conference (GLOBECOM), 2012
    Co-Authors: Ting Zhu, Qingquan Zhang
    Abstract:

    Wireless sensor networks (WSNs) are vulnerable to security attacks due to the broadcast nature of transmission and limited computation capability. After intrusion detection systems (IDSs) identifies an mobile intruder, IDS may broadcast the blacklist to all nodes in network. This method is energy inefficient because all nodes have to receive and forward the alarm packet so as to exhaust communication bandwidth and node energy, especially when there are a large number of sensor nodes in the network. This paper develops an energy efficient intrusion Prevention Mechanism in WSNs called green firewall. It can isolate an intruder with less overhead, and track the intruder to continually prevent the attack. The paper analyzes the overhead cost of the green firewall and compare it with the flooding broadcast method. Extensive analysis and simulations show that green firewall can prevent the attack and effectively reduce redundant alarm packet transmissions which results in less energy consumption.
