A communications infrastructure is necessary in order to integrate numerous devices on the smart grid. Among the key technology areas, the implementation of integrated communications infrastructure needs to be performed with the highest priority to build the smart grid efficiently. To encounter possible disruptions of the grid system, a highly reliable,(More)
The present study was carried out to evaluate genetic divergence among eleven japonica rice cultivars and to assess the relationship between genetic distance and hybrid performance in partial non-reciprocal crosses among them. The 44 F1 hybrids along with the eleven parents were evaluated for five cold tolerance-related traits; discoloration at seedling(More)
The brown planthopper (BPH) is a major insect pest in rice, and damages these plants by sucking phloem-sap and transmitting viral diseases. Many BPH resistance genes have been identified in indica varieties and wild rice accessions, but none has yet been cloned. In the present study we report fine mapping of the region containing the Bph1 locus, which(More)
We report the tagging of a brown planthopper (BPH) resistance gene (Bph–1) in rice using RAPD and RFLP markers. The Korean rice variety ‘Gayabyeo’ has dominant duplicate genes including Bph–1 conferring resistance to biotype 1 of BPH. Bulked segregant RAPD analysis was employed for rapid identification of DNA markers linked to resistance genes. For tagging(More)
Many Network Intrusion Detection System(NIDS)s have been developed to detect and respond against several kinds of intrusion activities in widespread networks. Due to the explosive growth of network bandwidth, software approach in developing a high-speed NIDS is becoming impractical due to the performance constraint. Accordingly, it seems unavoidable to(More)
BcN(Broadband convergence Networks) is being deployed in order to support a variety of network applications such as ECommerce, DMB(Digital Multimedia Broadcasting), Home Network, VoIP(Voice over IP), and other services. As network bandwidth is growing rapidly and services are converged, the opportunity and severity of network intrusions are growing as well.(More)
In this paper, we propose an intrusion detection system(IDS) architecture which can detect and respond against the generation of abnormal traffic such as malicious code and Internet worms. We model the system, design and implement a simulator using OPNET Modeller, for the performance analysis on the response capacity of alert information in the proposed(More)
This paper proposes Gigabit IDS to detect and respond against various attacks on high-speed links. Our proposed system has hardware-based stateful intrusion detection architecture that can provide the high-performance detection mechanism. It is possible through the pattern matching and heuristic analysis functions that are processed in FPGA Logic. In this(More)
BcN(Broadband convergence Network) is being deployed in order to support a variety of network applications, with enhanced capabilities of QoS(Quality of Service) provisioning and security, and IPv6. In a high-speed network environment such as BcN, it is more likely for the network resources to be exposed to various intrusion activities. The propagation(More)
