In this study, we have figured out exercise time and the amount of burned calories, using a three-axis acceleration sensor which we name as a health sensor. What is more, the health sensor calculates the degree of physical exercise taken during exercise. As is generally known, continuing, regular exercise is far more effective than short time exercise for sustainable health management. The health sensor is, therefore, recommended as an instrument to efficiently carry out the health management. Additionally, the health sensor was applied as an exercise subsidiary system to walking and jumping rope tests. In light of their results, the sensor system was found useful for analyzing the pattern of exercise.

As low power, low cost wireless communication technology like Bluetooth, Zigbee, RFID has been put to practical use together with the wellbeing trend, the concern about ubiquitous health care has been greatly increased and u-Health is becoming one of the most important application in the sensor network field. Especially, development of the medical services to be able to cope with a state of emergency for solitary senior citizens and the aged in silver town is very meaningful itself and their needs are also expected to continuously increase with a rapid increase in an aging population. In this paper we demonstrate the feasibility of extracting accurate heart rate variability (HRV) measurements from photoelectric plethysmography(PPG) signals gathered by a ring type pulse oximeter sensor attached to the finger. For this, we made 2 types of ring sensor, that is reflective and pervious type, and developed the remote monitoring system which is able to collect HR data from ring sensor, analyze and cope with a state of emergency.

This study was conducted to develop a electronic circuit of primary color reaction for urine analyzer for measuring color response of urine strip. A primary color reaction system is equipped with the computer, electronic circuit, tray, detecting assembly and software. The determination of coefficient($R^2$) between reagent and color sensor were 0.9801(R), 0.9868(G) and 0.9837(B). To evaluate the system verification, we measured the primary color reaction of erythrocytes, Bilirubin, Urobilinogen, Ketones and Protein. We concluded that it is possible to use the developed the primary color reaction system for urine analyzer using u-health.

Purpose： This study reviews the Youth Risk Behavior Surveillance System (YRBSS) in the United States. This review focuses on the purposes, questionnaires, survey methods, and use of survey results. The author also discussesthe establishment and use of Korean Youth Risk Behavior Surveillance System. Results：The YRBSS was developed in 1990 to monitor priority health risk behaviors that contribute to the leading causes of death, disability, and social problems among youth and adults in the United States. The purpose of YRBSS is to determine the prevalence of health risk behaviors, to assess the trend of health risk behavior prevalence, provide comparable data, monitor progress toward achieving the Healthy People 2010. The questionnaires inquire about health-related behaviors, including tobacco use, unhealthydietary behaviors, inadequate physical activity, alcohol and drug use, sexual activity, behaviors that contribute to unintentional injuries and violence. The results of YRBS have been used to estimate the prevalence of risk behaviors among youth, to set goals for school health programs, for training and development of health program personnel, for the development of health education curriculum, to support enactment of health-related regulations, and to support funding for futher research. Conclusions： The YRBSS represents a potentially valuable program that can be applied in Korea. Assessment of risk behaviors among Korean youths will provide invaluable insight for many potential purposes.

u-Life care device collect body bio formation, and classify and store them in exercise patterns. Afterwards, the devices send the data through bluetooth wireless communication to the smart phones which set Google Android operation system at regular intervals. The information is checked out through application. u-Life care device calculates calories spent a day after monitoring activity quantity with 3-axis acceleration sensor. The device judges the status of health through body data mining and consults tailored exercise treatment. When sending body data, the device sends them in smart phone through Blue Tooth wireless communication at once. So, as a strong point, the device doesn't need mobile gateway or home gateway used for sending to web server information sensed from exercise life care products.

A meso-urban meteorological model (Urbanized MM5; uMM5) with urban canopy parameterization (UCP) was applied to the high-resolution simulation of meteorological fields in a complex coastal urban area and the assessment of urban impacts. Multi-scale simulations with the uMM5 in the innermost domain (1-km resolution) covering the Busan metropolitan region were performed during a typical sea breeze episode (4~8 August 2006) with detailed fine-resolution inputs (urban morphology, land-use/land-cover sub-grid distribution, and high-quality digital elevation model data sets). An additional simulation using the standard MM5 was also conducted to identify the effects of urban surface properties under urban meteorological conditions. Results showed that the uMM5 reproduced well the urban thermal and dynamic environment and captured well the observed feature of sea breeze. When comparison with simulations of the standard MM5, it was found that the uMM5 better reproduced urban impacts on temperature (especially at nighttime) and urban wind flows: roughness-induced deceleration and UHI (Urban Heat Island)-induced convergence.
