In this paper, we try to proposal a new mechanism for optimizing the route of the Greedy parts of GPSR. By studying the GPSR, we find that the Greedy part of GPSR is not always to find the most optimized route, especially in the denser scenario. So according to this problem, we try to propose a mechanism to find an optimized route. In our proposal, we give(More)
BACKGROUND Recently, endoscopic clip application devices have undergone redesign and improvements to optimize their clinical use and effectiveness. Initially designed for the treatment of bleeding nonvariceal lesions, these devices are also increasingly used for the closure of perforations, fistulas, and anastomotic leaks. Several clinical studies, both(More)
BACKGROUND Numerous clinical trials to improve the success rate of biliary access in difficult biliary cannulation (DBC) during ERCP have been reported. However, standard guidelines or sequential protocol analysis according to different methods are limited in place. We planned to investigate a sequential protocol to facilitate selective biliary access for(More)
Vehicular Ad Hoc Network (VANET) is a new emerging technology which integrates all methods of transportation into a single manageable resource. To implement VANET, an effective network is required. General ad hoc routing protocols have been proved not suit enough for VANET. In this paper, we propose a novel vehicular ad hoc routing protocol which takes(More)
Myungseok Oh et al. 167 ABSTRACT⎯In this paper, we propose hardware architecture for a high-speed context-adaptive variable length coding (CAVLC) decoder in H.264. In the CAVLC decoder, the codeword length of the current decoding block is used to determine the next input bitstreams (valid bits). Since the computation of valid bits increases the total(More)
Precise time-of-arrival (TOA) estimation is one of the most important techniques in RF-based positioning systems that use wireless sensor networks (WSNs). Because the accuracy of TOA estimation is proportional to the RF signal bandwidth, using broad bandwidth is the most fundamental approach for achieving higher accuracy. Hence, ultra-wide-band (UWB)(More)
BACKGROUND/AIMS To determine the incidence and clinical characteristics of tuberculosis (TB) medication-associated Clostridium difficile infection. METHODS This multicenter study included patients from eight tertiary hospitals enrolled from 2008 to 2013. A retrospective analysis was conducted to identify the clinical features of C. difficile infection in(More)
