Observing the medication hours are critical to the patients but they often forget to keep them unconsciously and delay in recovery. Although some notification services are being carried out by calling the patients or sending out the recorded messages through portable devices to those who stay at the hospitals or at homes, such services do not cover most of them. The notification system described in this article utilizes a Mobile Push Service generally used in other areas. The system not only notifies the medication hours but also informs the user cautions and warnings when they take their medicine(s). The possible side effects caused by excess consumption and mixed usage will be informed as well. The system has been designed to let the users to easily identify the information they need and keep the hours of medication. By modifying this system, other more sophisticated applications will be possible.

Unprecedented attention is being given to Smart Grid, Micro Grid and Internet of Things (IoT) in the Republic of Korea recently but such systems' effect is not well experienced by the market since they require additional and costly reforms for the existing household electrical system where adaptive communication platforms are needed. As such platforms, both wireless and wire communication technologies are being considered at the moment. Usually, they include WiFi, Zigbee technologies and the latter, LAN technology. However, communication speed decline due to signal attenuation and interference during wireless communications are considered to be the major problem and the extra works involving time and costs for the LAN system construction can be another demerit. Therefore, in this paper, we have introduced a Power Line Communication-based Smart Outlet System Expandable at Home to complement these disadvantages. Proposed IoT system involves Power Line Communication (PLC) technology which is essential to constructing a Smart Grid.
