유엔의 통계에 의하면, 2020 년에 전세계 60 세이상의 인구는 10 억까지 달성하고, 2050 년, 전세계에 20 억 가까운 노인 인구가 생존하게 됩니다. 끊임없이 증가되는 세계의 노령화 문제 때문에, 혼자 생활하는 독거 노인은 끊임없이 증가하고, 동시에 노인들의 순환기질환 관련 위험성은 증대하고 있다. 따라서 본 디자인연구는 이러한 노인들의 문제를 해결하기 위해 외형은 손목 시계와 같이 손목에 차는 형태로 연구되었으며, 심장과 혈압 항상 검사 측정하는 기능이 있어서, 그 수치가 안전을 위협하고 있을 때, 119 나 친척들 또는 담당의사에게 전화로 응급처리를 요청하게 되고, GPRS 는 스스로 작동, 병원에 응급조치와 함께 가장 짧은 시간에 도착할 수 있도록 것을 한다. 동시에 제품에는 환자의 진료카드가 있어 담당의사가 아니라도 진료를 할 수 있도록 하는 기능을 가진 기기에 대하여 연구하였다. 이러한 기기가 노인들에게 사용되기 위해서는 노인의 특성을 고려한 특징적인 연구가 필요하며, 노인의 감성에 맞는 기기의 특성을 파악 적용하는 문제를 연구하였다.

As an integrated technology with IT and biomedical sciences, U-health offers various healthcare services without time and space limit. In order to make a proper diagnosis, doctors need two key technologies: biosignal measurement and high reliability communication technologies. In this paper, we introduce an implementation process of a bio signal system with using an electrocardiography(ECG) sensor, video, global positioning system(GPS), communication module and micro controller unit(MCU).

Fast response to livestock disease and raising the reproductive success rate contribute to the improvement of farm productivity and profit margins. Due to the decrease in farm workforce and aging population, efficient livestock healthcare and breeding management are needed. In this study, we developed a mobile application for livestock healthcare and breeding management based on the collected body temperature data by IoT sensors. In case of livestock health problem, users are notified immediately via a mobile application warning message. It also provides users with a livestock breeding date function, allowing them to respond without missing the breeding season.

In this study, a method for estimating the amount of urination for men, was suggested and its performance was evaluated. This study is a preliminary one for the development of a health monitoring system that needs un-constraining, non-intrusive and long-term measurements in daily life. To estimate the amount of urination, a wide weighing plate with load cell was built and the difference in a man's weights between before and after urination was measured while he was standing on the plate. The results showed that the amount of urination can be estimated with the measured weight difference under the condition of mild movements. The largest measurement error of the suggested method was 40g, which means that this method can be applied to health monitoring in daily life. It is expected that the results of this study will be the basis for developing practical un-constraining and non-intrusive health monitoring system for daily use at home.

This study is on the elderly people's use and experience of a wearable device. By using wearable device, the elderly can monitor their health data at real time. As a result, their motivation for health care, exercise, and so on can improve and enhance. Across the globe, population aging becomes one of the most important problems in each nation. The social and economic burden from aging is one of most serious challenges to sustainability of the world and its economy, including South Korea. Information Communication Technology including wearable device can help the elderly health care improve. In 2016, the number of wearable devices is more than 19 million. Many of them are the devices related to health data monitoring. In the experiment, the authors measure real time health data from the subjects' wearable devices. In the first experiment day, subjects' average waist size was 36.29 inches. In the final experiment day, 31st day later from start of the experiment, the average waist size was 35.51 inches. At the beginning of the experiment, standard deviation was 1.93. At the final day of the experiment, it was 2.24. In regression analysis, when experiment day extends, average waist size seems to decrease. The trend is significant (t=2.719, p<0.05). That result may mean the subjects' motivation for health care improve. Wearable device can increase the elderly people's motivation for health care and exercise. As a result, their health can improve.

For patients who have senile mental disorder such as dementia, quantity of excercise and amount of sunlight are important clue for dose and the treatment. Therefore, monitoring health information of daily life is necessary for patients' safety and healthy life. Portable & wearable sensor device and server configuration monitoring data are needed to provide these services for patients. Watch-type device(smart watch) which patients wear and server system are developed in this paper. Smart watch developed includes GPS, accelerometer and illumination sensor, and can obtain real time health information by measuring the position of patients, quantity of exercise and amount of sunlight. Server system includes the sensor data analysis algorithm and web server that doctor and protector can monitor through sensor data acquired from smart watch. The proposed data analysis algorithm acquires quantity of exercise information and detects step count in patients' motion acquired from acceleration sensor and to verify this, the three cases with fast pace, slow pace, and walking pace show 96% of the experimental result. If developed u-Healthcare System for dementia patients is applied, more high-quality medical service can be provided to patients.

하천의 건강성을 유지하고 수환경의 정상적인 기능을 회복하기 위해서는 수서생물들에게 알맞은 서식환경 조성, 점오염원 및 비점오염원 차단, 적절한 유량과 같은 다양한 조건이 요구된다(Gore 1895; Gore et al. 1989). 이 중 유량은 수생태계를 이루는 물리적, 화학적, 생물학적 요소들 가운데 기본이 된다고 할 수 있다(Bunn and Arthington 2002; Nilsson and Svedmark 2002; Arthington et al. 2006). 국내 하천관리를 위한 하천유지유량의 산정에서 고려하고 있는 갈수량, 하천생태계, 하천수질 등 8가지 항목 가운데 최근 생태계와 환경에 대한 사회적 국민적 관심이 증가하면서 하천생태계를 고려한 환경유량의 중요성이 부각되었으나, 현실적으로 생태계를 고려한 정량적 조사자료 구축 및 환경유량산정 등의 객관적 자료는 미흡한 실정이다. 특히, 과거 해당수계 및 하천의 어류분포 현황 파악을 중심으로 이루어진 어류조사는 환경유량 산정 시 기초자료로 활용하거나 직 간접적으로 어류상이 변화하는 원인을 분석하는 자료로 활용하기에는 객관성이 결여되어 있다고 할 수 있다. 어류모니터링 기법 확립은 환경유량산정에 있어 요구되는 정량화와 자료의 객관성을 높이기 위한 작업으로 문헌조사와 청문조사를 포함한 사전조사, 현장조사, 조사결과 정리, 고찰 등의 총 4가지 과정을 기본으로 실시하는 것으로 정하였다(그림. 1), 청문조사와 문헌조사 등의 사전조사를 통해 기존자료를 확보하고 현장의 답사, 조사구간, 방법, 시기 등의 선정을 통해 두 번째 단계인 현장조사의 효율성을 높였다. 현장조사에서는 어류분포 현황 외에도 해당지점의 하상재료, 식생, 유속, 수심, 수질 등 조사지점의 수 환경요소 전반을 기록하여 어류의 서식과 물리 화학적 수환경과의 상호관계를 파악하고자 하였다. 마지막으로 고찰단계에서는 조사 대상 지역 전반적인 어류상 특징과 함께 보호종, 한국고유종, 외래도입종 출현유무 및 빈도, 물리적, 화학적 수환경의 특징, 수환경에 따른 어류상 특징 등의 분석과 함께 조사하천의 건강성을 평가하고자 하였다. 본 연구는 어류모니터링 기법 확립을 통해 환경유량산정 시 요구되는 객관적 기초자료를 구축하고 나아가 오염물질 유입, 하천정비사업 등의 각종 교란요인에 의해 발생할 수 있는 문제점들에 능등적으로 대처하고 교란에 의해 악화된 수환경의 복원을 위해 요구되는 객관적 기초자료 생산에 목적이 있다.

Mobile Healthcare is a new type of health care services for managing health and life irrespective of time and space by uniting IT and BT. For this service bio-signal measurement using WBAN, and data analysis and monitoring technologies based on mobile devices are essential. Generally, however, mobile application has low compatibility because of the features of mobile platform, we have to redevelop it to support the corresponding platform. In this paper we introduce a Mobile Healthcare System which can function as gateway and monitoring based on hybrid app to create ubiquitous healthcare monitoring system compatible with various mobile devices by overcoming the difference of platforms. The proposed system consists of sensor composition part, monitoring composition part, and server composition part.

Because worldwide interest in the health is increased, the real-time health monitoring system has been demanded to be more convenient non-contact and precise medical devices than conventional. Therefore we developed the blood pressure monitoring system using UWB(Ultra Wide Band) radio wave which contact to the human body through the radar and continuously collect a movement signal of the blood vessel. Then the collected data including pulse rate, systolic blood pressure, diastolic blood pressure is processed in real time. The system monitors and controls through a program-based embedded LCD(Liquid Crystal Display) using Qt GUI(Graphic User Interface) to be displayed in real time. We implement the system as a embedded system because of reducing the size of the limited resources. Existing PC GUI design mode is used relatively large memory, therefore it requires more CPU(Central Processing Unit) capacity and processing time.
