  • In this paper the automatic system for dairy cattle has been desisted such as body temperature measuring unit, feed supplying unit and temperature control unit. Since e disease is strongly related to the body temperature of cattle, early detection of the abnormal temperature would prevent the severe problems which nay occur in dairy farms. An electronic component AD590J is used as temperature sensor for the system, The device is highly robust against the noise since the output signal is the current so it can be applied to a long distance sensing The resolution of signal is 0.1$^{\circ}C$ and the current is 10㎷ Also 12-bit A/D converter is desisted fir interfacing the sensor with a one-chip microprocessor. A temperature measuring experiment using the developed system has been done for measuring the temperature of human beings and the system was proven to be useful for measuring the body temperature of dairy cattle properly. A geared AC motor is used for the feed supplying unit The heater and fm are used as temperature control unit. The feed supplying unit and temperature control unit are well operating in the laboratory experiment.

  • In this paper the development of an automatic body temperature measuring system which can be attached to the milking machine has been studied. Since the disease is highly related to the body temperature of the cattle, early detection of the abnormal temperature would prevent the severe problems which may occur in dairy farms. The electronic component AD590 is used as a temperature sensor for the system. The device is highly robust against the noise since the output signal is the current. So it can be applied to the long distance sensing. The resolution of the signal is $0.1{\circ}C$ and the current is 10 mV. Also the A/D converter is designed for interfacing the sensor with a computer. A temperature measuring experiment using the developed system has been done for measuring the temperature of human beings and the system was proven to be useful for measuring the body temperature of the dairy cattle properly.

  • 본 연구에서 우슈 도장에서의 수련자 신체활동량을 과학적, 정량적으로 분석하여 스포츠의학의 중요한 관심사인 질병의 예방과 만성퇴행성 질환의 조절과 관리 그리고 건강을 증진할 수 있는 방안을 제안한다. 신체활동량을 측정하기 위해 신호획득 장비는 body media사에서 개발한 SenseWear PRO2 Armband를 사용하였다. Armband내에는 체온계(skin temperature sensor), 온도계(near-body temperature sensor), 가속도센서(accelerometer), 몸에서 발산되는 열량을 측정하는 센서(heat flux sensor), 피부의 전기전도도를 측정하는 센서(galvanic skin response sensor)가 있다. 각각의 센서로부터 획득한 데이터는 Armband내의 저장장치에 기록하였다. Armband에 저장된 데이터를 InnerView Wearer Software를 이용하여 우슈 도장에서 수련자의 신체활동에 따른 피부온도변화, 칼로리 소모, 활동량 추이변화를 분석하였다. 연구결과 지속적으로 오랜 기간 동안 운동을 한 사람은 단시간에 많은 에너지 소모를 하는 것으로 나타났으며 Physical activity가 활발하면 에너지 소모가 증가하고 동시에 피부 온도가 상승하는 것을 알 수 있었다. 에너지 소모가 증가하면서 피부온도가 증가하고 난 후 열 발산이 일어나는 것을 실험결과 알 수 있었다. 그리고 피부전도는 Physical activity, 에너지 소모, 피부온도 증가 등의 인자에 아무런 영향을 받지 않는 것으로 나타났다.

  • The wireless sensor network (WSN) based ECG and body temperature measuring system for ubiquitous health-care were designed and developed. The system was composed of a wireless sensor network node, base station and server computer for the continuous monitoring of ECG signals and body temperatures of patients at home or hospital. ECG signal and body temperature data, important vital signals which are commonly used in clinical and trauma care, were displayed on a graphical user interface (GUI). The data transfer from sensor nodes on patients' body to server computer was accomplished through a base-station connected to a server computer using Zigbee compatible IEEE802.15.4 standard wireless communication. Real-time as well as historical, ECG data of elderly persons or patients, can also be retrieved and played back to assist the diagnosis. The ubiquitous health care system presented in this study can effectively reduce social medical expenses, which will be increased greatly in the coming aging society.

  • Typically, the vital signs that are representing the state of human body, are the body temperature, sphygmus, respiration and blood pressure. The body temperature is the result of metabolic regulation and human steady-state body temperature is maintained from 35.9 to $37.4^{\circ}C$ by heat regulatory center. The body temperature is indicative of infection and especially it should be monitored to requiring intensive care patients or after surgical patients. But, measuring of body temperature to a heavy workload on nursing staff has been recognized. And, the health service of nurse is limited by simple tasks such as the measurement and record of vital sign. In this paper, the body temperature monitoring telemetry system was proposed to prove the recoding and transmission of body temperature patch system according the standard(ISO TS11073-92001). We proposed the transmission protocol to suit the MFER(medical waveform format encoding rules). The telemetry patch system was implemented and it was verified by experiments.

  • A Wireless Body Area Network (WBAN) allows the seamless integration of miniaturized sensor nodes in or around a human body, which may cause damage to the surrounding body issue due to high temperature. Although various temperature aware routing protocols have been proposed to prevent temperature rise of sensor nodes, most of them accommodate single traffic transmission with no mobility support. We propose a Forwarder based Temperature Aware Routing Protocol (FTAR) that supports multiple traffic transmission for normal and critical data. Normal data is forwarded directly to the sink through forwarding nodes which are selected among mobile nodes attached to the arms and legs, while critical data is forwarded to the sink through static nodes attached to fixed body parts with no mobility. We conduct extensive simulations of FTAR, and conclude that FTAR has good performance in terms of hot spot generation ratio, hot spot duration time, and packet delivery ratio.

  • This paper presents a wearable human health-monitoring band. The band consists of a body temperature detector (BTD) and a hear rate detector (HRD). The BTD and HRD are realized using an inkjet-printed flexible temperature sensor and a commercial heart rate sensor module, respectively. The sensitivity of the fabricated BTD was found to be $-31/^{\circ}C$ with a linearity of 99.82%. The HRD using the commercial heart rate sensor module has a good performance with a standard deviation of 0.85 between the data of a commercial smart watch and the fabricated HRD.

  • 본 논문에서는 전기설비의 전기적 접속부 또는 전기배선 등에서 발생하는 이상발열을 감지하는 방법에 대해 알아보고, 분전함에서의 발열상태를 실시간으로 모니터링하는 전력설비 진단시스템에 사용되고 있는 광온도센서에 대하여 동작특성을 실험, 분석하였다. 광온도센서의 동작특성 실험을 위한 열원으로는 Black Body와 Hot Plate를 사용하였으며 각각에서의 열원의 온도변화에 따른 광온도센서 출력전압값을 측정, 분석하였다. 그리고 분전함내 차단기 단자에서의 체결불량으로 인한 이상발열 감지 실험을 기존의 발열 감지방법인 열전대와 적외선 열화상장치를 이용하여 실시하였고, 광온도센서를 이용해 실시하여 결과를 비교 분석하였다. 실험결과, 광온도센서의 이상발열 감지능력이 유사함을 확인할 수 있었다. 이러한 분석 결과는 향후 RFID형 광온도센서를 이용한 전력설비 진단시스템의 현장 적용에 있어 기본 자료가 될 것으로 기대된다.

  • 무선센서네트워크는 처리능력과 자원이 제한된 수많은 소형의 센서노드들로 구성된다. 따라서 무선센서네트워크에 있어서 가장 중요하고 기본적인 요소는 환경 정보를 수집하고 이를 사용자 응용시스템에 전송하는 센서노드 기술이다. 기술의 발전에 따라 센서노드는 점점 소형화 되고 지능화 되어 그 응용범위를 넓혀가고 있다. 특히 이식형 센서노드 기술은 인체나 가축의 체내에 이식되어 질병을 감시하고 치료하는데 사용됨으로써 무선센서네트워크의 미래 발전 방향을 제시한다. 본고에서는 가축의 체온을 실시간으로 감시할 수 있는 이식형 무선 센서노드를 설계하였다. 또한, 실시간 생체 감시 시스템 구현을 위한 추가적인 고려사항에 대하여 논하였다.
