This study was realized the home network system for home care by bio-physical sensor system, to convey for the remote physical signal. The composition condition has four functions of displacement point for a Vision, Somatosensory, Vestibular and CNS that the basic measurement used to a Heart Rate, Temperature, Weight. Physical signal are decided to search a max and min point with adjustment of 0.01 unit in the reference level. There were checked physical condition of body balance to compounded a physical neuroceptor of sensory organ for the measurement such as a Vision, Somatosensory, Vestibular, CNS, BMI. There are to check a health care condition through a combination of physical organ with a posturography of a exercise. The service of home network system can be used to support health care management system through health assistants in health care center and central health care system. It was expected to monitor a physical parameter for the remote control health management system.

To improve the sense of unity between game players and game world avatars, we propose a method to measure game player's physical status and manipulate game character appearances and behavior using the measurements. To measure the status, we implemented a hardware module that perceive the body temperature. We implemented a 3D horror game whose game space is a common subway space ordinarily encountered in daily life so that ordinary people can easily get used to the game environment. The experiments of applying the measurement data from the game player to the game world avatar shows that the player's physical status can be effectively utilized to improve the sense of reality in gameplay.

This paper presents a manufacture of the multiple subjects biotelemetry system using custom CMOS IC fabricated $1.5{\mu}m$ n-well process technology. The implantable circuits of the system except sensor interface circuits including FM transmitter are fabricated on a single chip with the sire of $4{\times}4mm^{2}$. It is possible to assemble the implantable system in a hybrid package as small as $3{\times}3{\times}2.5cm$ by using this chip, It's main function is to enable continuous measurement simultaneously up to 7-channel physiological signals from the selected one among 8 subjects. Another features of this system are to enable continuous measurement of physiological signals, and to accomplish ON/OFF switching of an implanted battery by subject selection signal with command signal from the external circuit. If this system is coupled with another appropriate sensors in medical field, various physiological parameters such as pressure, pH and temperature are to be measured effectively in the near future.

An ubiquitous healthcare monitoring system for elderly person at home was designed for continuous healthy monitoring of elderly person or patients. Human vital signals, such as ECG and body temperature, were monitored by terminal PC or PDA via ECG and temperature sensor nodes on the patient's body. From the ECG data, the heart rate, tachycardia, bradycardia and arrhythmia were diagnosed on the terminal PC or PDA to assist doctor's or nurse's aid or patient itself to monitor the patient's condition and give medical examination. Artificial judgement support system was designed in server computer and the system support a doctor or nurser for management or treatment of the patient. This system can be applied to vital signal monitoring system for solitude elderly person at self house or home health care service part. And this ubiquitous healthcare system can reduce the medical expenses in coming aging or aged 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.

Today, livestock industry grows faster and bigger. The number of livestock numbers per farm also grows rapidly. The bigger farms need more sophisticated control of livestock to prevent from all possible diseases, especially contagious diseases. In Korea, diseases cause serious economic loss of 2 trillion won every year, which is about 20% of the total production output. Researches on the wireless bio-signal monitoring technology for livestock are of great importance in the world. In this paper, as a way to predict the possible diseases, we propose a measurement method of the pulse of dairy cows for the continuous health monitoring. It is possible to measure a pulse from central artery and the left chest-wall of the cow. The pulse from central artery is measured by the sensor attached at the tail winding. The pulse at the left chest-wall can also be measured with our newly designed harness.

사람들의 건강에 대한 관심이 증가하면서 이러한 사람들의 요구사항을 만족시킬 수 있는 다양한 서비스가 개발되어지고 있다. 헬스-관광 서비스는 관광 서비스와 헬스 서비스를 접목하여 관광객의 건강관리를 도와주는 서비스이다. 헬스-관광 서비스는 PDA의 지리정보 및 관광정보를 활용하여 방문할 관광지역과 이동방법을 선정한다. 시스템은 사용자의 기본 정보와 이동반경을 계산하여 사용자의 예상 운동량을 산출하여 보여주고, 사용자는 해당 정보를 바탕으로 전체 관광코스를 선정한다. 실 운동량 측정은 관광객의 이동거리, 이동속도, 고도, 맥박, 체온 등의 정보를 이용하여 측정하고, 측정된 운동량을 사용자에게 알려준다. 또한 실 운동량이 예상 운동량과 비교하여 과도하거나 부족한 경우 관광코스의 수정을 유도하여 적정량의 운동을 할 수 있도록 코치할 수 있다. 본 논문에서는 헬스-관광 서비스 시스템의 서비스 방법을 제안하고, 헬스-관광 서비스 시스템을 설계하였다.

Due to the rapid development of Internet-of-Things technology, different types of smart sensors are now devised and deployed widely. These smart sensors are now used in animal husbandry which was traditionally managed by the experience of farmers, such that wearable sensors for livestock, and the smart farm which is equipped with multiple sensors are utilized to increase the efficiency of livestock management. Herein, we consider a scheme in which the body temperature and the level of activity are measured by smart sensor which is attached to the neck of dairy cattle and the health condition is monitored based on collected data. Especially, we find that the estrous of dairy cattle which is one of most important metric in milk production, can be predicted with high precision using various machine learning techniques. By utilizing the proposed prediction scheme, estrous of cattle can be detected immediately and this can improve the efficiency of cattle management.

Accidents of worker that occur in isolated places are difficult to rescue, unlike general construction accidents. There is a problem of communication limitation when an accident occurs in an isolated place. Also, it is difficult to search the accident place due to the absence of CCTV. In order to solve these problems, this paper proposes a device that combines IoT technology with a safety helmet, which must be worn in the workplace. The proposed device additionally designs and implements a real-time PPG(Photoplethysmography) sensor, body temperature sensor, accelerometer sensor and a camera sensor on the helmet. The proposed helmet system allows the user and the control center to monitor the state of the worker. In addition, when an abnormal biological signal or fall occurs to the worker, the image is transmitted to the control center. By using the proposed system, it is possible to check the status of the worker in real time, so that it has an advantage that it can cope with the accident quickly.
