When looking at the online copyright infringement, the advertisements have served as a revenue source. Recently, copyright holders and state agencies have requested to stop and withdraw posting the ad. in order to prevent copyright infringement. This way is very easy and efficient. However, the problem is that it is not clear whether the request is appropriate. For the request to be valid, posting the ad. should be a kind of indirect infringement, or if not, it must have a suitable reason. If there is no basis or reason for the two, the request should not be asked recklessly. In the US relevant cases, something more than simple relationship with direct infringers or more material contribution to the direct infringement is required to impose secondary liability for copyright infringement. However, just posting the ad. cannot be considered as the close relationship and moreover, it is not material contribution. Thus, posting the ad. is not secondarily liable for copyright infringement. In addition, the bills which was proposed in 2011, so called SOPA and PIPA, had a provision which can stop and withdraw the ads in the piracy sites. Its opponents raised the following problems: withdrawing the ad. is the censorship, gives the burdensome to the sites, and causes the imbalance due to the overload protection of copyright. Also, under the ad blocker case, to remove the ad. discretionally consists of illegal activity or copyright infringement. As a result, because the request to stop and withdraw posting the ad. is not reasonable, the request should be asked carefully.

Many posters and advertisements for fire prevention have long been known to warn of the danger of fire. The reason for this warning is that the damage of the fire is large. In addition, if the second damage occurs, the damage will be larger. In this study, we will design an automatic power circuit breaker that automatically cuts off the power if the temperature sensor is set to a certain temperature value and then goes up above that value. This study will minimize the secondary damage of fire.

인터넷이 발전함에 따라 기업의 업무, 커뮤니케이션 등이 온라인으로 전환되고 있으며, 정보전달의 통로로써 전자 메일의 사용이 나날이 늘고 있다. 이에 따라 전자 메일을 통한 바이러스, 스팸 광고 등 메일의 컨텐츠를 이용한 공격에 의한 피해가 심각한 수준에 이르고 있다. 현재 방지 대책으로는 백신이나 스팸 메일 차단기 등을 통해 방지 기능을 제공하고는 있으나 이는 사용자의 의지에 의존적이며, 개개 시스템에 한정되는 한계가 있다. 따라서 사용자의 의지와 무관하게 네트워크 차원에서 내부 네트워크를 보호하기 위한 방지 대책이 필요하며 이에 본 논문에서는 기존의 침입 탐지 시스템을 확장하여 메일 컨텐츠를 탐지할 수 있는 확장된 침입탐지 시스템을 제안한다.
