In this study we report the development of a new type of optical Fiber Bragg Grating(FBG) sensor system for the purpose of structural health monitoring. We have compared the results obtained by using three kinds of FBG sensors with conventional electric sensors in bridge health monitoring. Strain, displacement and acceleration measurements were conducted to determine the health or condition of the bridge. These results show good agreements between FBG and electric sensors. A higher level of signal sensitivity was obtained in case of FBG as compared to the electric sensors. This study thus proves that FBG sensors are a promising alternative in structural health monitoring systems as they overcome the electrical noise drawback.

As internet technology develops and there are increases in cyber activities such as e-mail, SNS and e-commerce, cyber security is being emphasized as one of the most important social issues. In particular, spam mail, SMS phishing and other malicious URLs to breach personal data are inflicting financial and physical damage. This paper proposes a malicious URL detection method based on search volume from internet search engines to resolve such problem. The search volume-based malicious URL detection method uses portal search engines to automatically search URLs linked to emails, text messages and SNS to determine whether or not they can be categorized as malicious URLs according to the volume of the search result. This method allows normal URLs, but will protect to abnormal behaviors.
