This study is regaring a new design of system to detect cracks in the tunnel while the vehicle is moving. There was a limitation and inefficiency in existing tunnel scanning system that should prevent vehicle traffic for the tasking and inspect the crack with slow moving. New system is designed for equipping on the roof of the vehicle and using video to inspect the crack. And it improved resolution of the inspected picture with synchronized algorithm by hardware flashing. By this experimental study, the new system implements to shoot inspection image up to 15 pictures per second under 80km/h high-speed moving. And it enhanced the clearness of recording video by using synchronized signal algorithm and enable to inspect up to 4M lining of the tunnel.

This paper suggested and analyzed the multiple feedback filter systems which improves ICR system’s performance. The proposed system used the adaptive LMS algorithm which can apply the weight value according to the channel environment and multiple sub filter blocks. We designed ICR(Interference Cancellation Repeater) and simulated convergence speed according to the channel condition for analyzing the multiple feedback filter's performance. In simulation results, it has been shown that the proposed filter system is able to cancel the interference of the ICR and to improve hardware's performance because of the proposed filter system's fast speed.

Hypertensive intracerebral hemorrhage is a high risk disease as it can induce sudden physical paralysis and decreased consciousness as a result of cerebrovascular circulatory disturbance. Also, the guardians of hypertensive intracerebral hemorrhage patient may experience anxiety during the patients absence. To deal with such problems effectively, a real-time patient tracking service is vital which makes use of smartphones and PC to help track the patients whereabouts. In this study in order to more effectively provide services for patient tracking system is proposed. This service suggests a patient monitoring system that can provide the GPS coordination and spatial information of the patients in real time.

This paper is wrapped around the heating wire, such as water and sewage pipes in plumbing and fire protection water pipes and winter apartments and buildings for frost protection system to prevent freezing. Characteristics of the frost protection system is a system that generates heat by supplying current to the heating wire wound around the pipe. In this paper, we will effectively control the current supplied to the heating coil and to design a system.

본 논문은 하천 원격 감시 시스템에 주로 사용되는 RTU의 성능을 개선하기 위한 고속의 임베디드 시스템을 적용한 RTU시스템 설계에 관한 연구이다. 본 논문에서 제안한 하천관리용 RTU는 모듈단위로 구성되어 있으며 확장이 용이하도록 시스템을 구성하였다. RTU의 상태를 감시할 수 있도록 고장에 대한 진단기능 부가 하였으며 Web Sever 기능을 부가하여 원격지에서 하천의 상태를 쉽게 모니터링 할 수 있도록 시스템을 개발하였다. In this paper, we designed RTU of the remote monitoring system for performance to improve of RTU using the embedded system with high-speed. The proposed river management RTU system consists of a modular unit system was constructed to facilitate the expansion. RTU to monitor the status of the fault diagnostic capabilities for additional functionality and add Web Sever river in a remote location to allow easy monitoring of the state system has been developed.

This paper presents a design and analysis of a gateway for cold chain monitoring. In order to do this, a sensor for collecting data from sensors and communication modules such as ZigBee, Bluetooth and active RFID were used. The communication module between the gateway and server was designed using Ethernet, WiFi, and LTE modules. For our experiment, a gateway implemented using ZigBee, Bluetooth and WiFi modules was made and we collected data of temperature, humidity, and vibration every 5 minutes. As a experimental result, we found out that we could collect data from 50 meters away when there are no obstacles, and 20 meters when there is.
