ECG widely used in cardiac function test is a graph that is recorded by measuring the electrical impulses occurred in the heart. Normal ECG has the form of similar sections that are repeated, and each section has the information occurred in a heart beat. Thus, In order to make the correct diagnosis, correct grasp of the sections and formed analysis must be done. In this research, a system that detects the sections of ECG is proposed. The system is based on ECG stored in the form of files. The ECG can easily have a noise caused by an outside factor. The noise of ECG is easily caused by external factors. Through a band-pass filter, it can be removed. and then, to get this ECG without a noise, interval detection algorithm using R-peak is applied. The clean, intuitive interface will help the above functions to be used without any difficulties.

In this paper, the particle swarm optimization (PSO) algorithm is adopted to design a modified ring-slot type patch rectenna with a resonance frequency of 2.45GHz. In order to accomplish minimization of dimensions and circular polarization (CP) and harmonic suppression, axial direction slits and side-cuts are added to the patch of the ring. The PSO manipulated this kind of multi-dimensional problem very well, and as a result, the designed rectenna shows a desirable performance of return loss of 21.36dB and axial ratio of 2.92dB at the frequency of 2.45GHz with compact sizing.

In recent years the USN(Ubiquitous Sensor Networks) technology has been applied in the greenhouse in order to control temperature and humidity automatically. In this paper, we proposed a control algorithm using feedback linearization techniques based on a mathematical model for temperature and humidity environment. Especially, Control algorithm is presented to the operation of the ventilator affecting on the temperature and humidity system at the same time. The System has been designed taking into account the disturbance(External temperature, soil temperature, external humidity, solar radiation and wind). In conclusion, I will present a way to control multiple actuator through simulations. The proposed control algorithm is validated using the Matlab / Simulink tools.

In this paper deperm performance on deperm protocol cycle has been analyzed. As deperm protocol increases cycle, deperm performance improves and duration time will increase. Thus, it's essential that proper deperm cycle that is fit on vessel should be applied. To compare deperm performance according to cycle changes, small deperm system has been made and small vessel had been made with SM45C materials. As Anhysteretic deperm protocol applied, the result on the increase of deperm performance according to the increase of cycle has been gotten.

In this paper describe configuration about QCM system for image processing device. It presents that QCM's image processing board video from the camera recognized by the PLC's battery removable exact location coordinates to the robot image processing technology to deliver. In addition, QCM video image processing technology for improved data reliability is described. In this paper define the landmarks of battery for obtaining the location coordinates and verify battery the location coordinates acquisition process from field tests of the QCM/QTPE-BUS Battery Exchange System.

최근 중요한 사회적 이슈로 떠오르고 있는 고독사를 예방하기 위해 IT- BT 융합을 기반으로 한 U-health care 시스템 및 서비스가 제안되고 있다. 그러나 최근 제안된 방식은 착용형 센서만을 이용하기 때문에 장기간 사용할 수 없는 단점을 가지고 있다. 이에 본 논문은 착용형 센서와 고정형 센서를 함께 이용하여 휴대용 센서의 수명을 극대화하면서 고신뢰성을 유지할 수 있는 지능형 상태 모니터링 시스템과 휴대형 센서의 소비전력을 줄이기 위한 AM-TPC (active margin transmission power control) 기반의 저전력 네트워크 기술을 제안 한다. 이와 더불어 구현된 저전력 지능형 상태모니터링 시스템을 기반으로 저전력 네트워크 실험을 하였을 때 50%의 전력이 감소된다는 결과를 도출하였다.
