Botnets are a disastrous threat because they execute malicious activities such as distributed denial-of-service, spam email, malware downloads (such as eggdownloads), and spying by exploiting zombie PCs under their control. Botnets infect PCs on a huge scale by initially scanning the service ports of vulnerable applications for the purpose of propagation,(More)
We investigated the effect of long-term oral administration of ethanolic extract of Angelica gigas Nakai (Umbelliferae) (EAG) or decursinol, a coumarin isolated from A. gigas, on beta-amyloid peptide 1-42 (Abeta(1-42))-induced memory impairment in mice. Mice were allowed free access to drinking water (control) or water containing different concentrations of(More)
Antinociceptive profiles of decursinol were examined in ICR mice. Decursinol administered orally (from 5 to 200 mg/kg) showed an antinociceptive effect in a dose-dependent manner as measured by the tail-flick and hot-plate tests. In addition, decursinol attenuated dose-dependently the writhing numbers in the acetic acid-induced writhing test. Moreover, the(More)
Prevention, not reaction, is normally recognized as one of the best defense strategy against malicious hackers or attackers. The desire of deploying better prevention mechanism motivated many security researchers and practitioners to develop a threat trend analysis model. However, threat trend is not directly revealed from the time-series data because it is(More)
The mobile internet environment which is in the limelight as the important platform of the ubiquitous environment gets accomplished by the intimate relation with user. In order to realize the interaction between device and user, it is considered that resource of exterior/interior user information which can be collected by mobile device and the(More)
The aim of this study was to investigate the effects of antidepressant treatment on serum cytokines and nutritional status in hemodialysis patients. Twenty-eight hemodialysis patients with a depressed mood were given 20 mg of fluoxetine for 8 weeks. The degree of depressive symptoms, the serum levels of interleukin-1beta, interleukin-2, interleukin-6, tumor(More)
Jellyfish cause a range of problems: they sting beach vacationers in the summer, block nuclear power plant intakes (thus disrupting the supply of electricity), decrease fishery catches, cause fishing activities to be delayed, decrease product value, and damage fishing gear. This study gauged the types and amount of damage directly caused by jellyfish. Using(More)
