The emergence of diverse medical Internet of Things (IoT) devices has facilitated the collection and analysis of medical contexts to assess health conditions. However, the complexity of IoT-based systems for health assessment is quiet high and it requires high development cost, since the designs of the systems highly depend on the heath aspects to be evaluated. In this paper, we propose a design of the platform that provides generic functionalities to various health evaluation applications. We first define a metric for computing a health index, which is a generic health assessment model. And, based on the proposed generic health index, we propose a design of the platform to evaluate diverse aspects of the health including its hardware architecture, software architecture and database design. We describe the result of developing Rainbow Toilet System based on the proposed platform, and assess the practical applicability.

As human life span has increased, people have wanted to live healthier desires. Especially Korea has rapidly entered an aging society, leading to the burden of medical expenses to the increase of disease accompanying aging. To alleviate the burden of medical expenses, prediction and prevention are important rather than treatment of diseases. It is possible to predict and prevent diseases by measuring individual genetic information. In order to utilize individual's genetic information Korea's genetic information is grasped through SNP (800 thousand) and GWAS optimized for the discovery of genetic factors of phenotype and disease of Koreans, The genetic information of each individual is analyzed in the genetic (constitutional) characteristics of the individual. In this thesis we develop a classification index so that we can classify populations of specific chronic diseases (obesity, diabetes or cardiovascular system). Try to develop health care services to manage custom diet and exercise associated with chronic illness.

Stress is a common risk factor for health and is associated with the endocrine gland and immune system. Studies on the association between stress and biochemical factors have been conducted worldwide, but studies on the association have been rare in South Korea. Therefore, the aims of this study are to analyze the relationship of stress with demographic information and biochemical factors for domestic adults and derive risk factors for stress. For data analysis, stress and normal groups were analyzed using binary logistic regression. In both men and women, age and average daily sleep time during the weekday were highly associated with stress, and the depression score (Patient Health Questionnaire-9) was also highly related with stress. In women, white blood cell levels were highly associated with stress, and in men, red blood cell levels were highly related with stress. These findings will contribute to the prevention of stress and the national health in the future.

Recently, smart wearable devices for monitoring health status have been utilized as interest in health care has increased. In this paper, we developed a fatigue measurement system that works with smart wearable devices. Unlike physical fatigue that is restored when you take enough rest, mental fatigue can decrease the efficiency or concentration of work, so you can monitor your mental health status through measurements. This system provides the function to transmit the measured data from the smart wearable device to the smartphone and to calculate the mental fatigue. A fatigue index was developed to measure fatigue and expressed as a number from 1 to 5. In addition, the results of the fatigue calculation and the survey were compared with the results of the independent sample t-test. Therefore, this system will be used to help users manage their health efficiently.

This study aimed to evaluate the plasma concentration of NT-proBNP in dogs with different stages of heart failure by chronic mitral valve insufficiency (CMVI). Fifty small-breed dogs with CMVI and 7 healthy control dogs without cardiac disease and critical systemic diseases were included in the study population. As a preliminary study, we compared the plasma concentrations of N-terminal pro-brain natriuretic peptide (NT-proBNP) and the echocardiographic parameters between dogs of the International Small Animal Cardiac Health Council (ISACHC) classes. Then, we evaluated the associations between NT-proBNP and echocardiographic parameters. Plasma NT-proBNP levels showed a significant difference among the ISACHC groups. In the comparison between echocardiographic parameters and NT-proBNP, NT-proBNP were found to be associated with left atrium/aorta (LA/AO), early diastolic transmitral flow (E) velocity, late diastolic transmitral flow (A) velocity, end diastolic volume index (EDVI). Our study found plasma NT-proBNP might be useful to predict the disease progression in dogs with CMVI.

WBAN(Wireless Body Area Network)기반의 의료 응용으로 실시간 모니터링 시스템을 구현하였다. 특히 산소포화도 생체 센서들로부터 연속적으로 전송되는 스트림 데이터에 대해 다양한 조건을 포함하는 질의들이 실행 되는데 이러한 실시간 모니터링 질의들을 효율적으로 식별하기 위한 질의 인덱스를 설계하였다. 매번 모든 질의들을 실행하기에는 시간이 많이 걸리기 때문에 Interval Skip List 를 이용하여 빠르고 효율적으로 식별하도록 설계하였다. 이로써 위급한 상황의 환자의 건강에 문제가 생겼을 때 신속하게 대처할 수 있는 환경을 제공한다. 본 논문에서는 방대한 양의 스트림 데이터와 이 데이터를 실시간으로 감시할 수 있도록 Interval Skip List 를 스마트 메디컬 스페이스(m-MediNet)에 적용한 방법을 기술하고 있다.

Smart Society로 나아가는 핵심으로 손꼽히는 모바일의 급속한 확산은 교육, 교통, 경제뿐만 아니라 건강에도 큰 영향을 미치고 있다. 그동안 발전이 미진했던 u-Health 기술 및 시장 역시 모바일로 인해 새로운 서비스 모델을 제시함으로써 발전하고 있다. 본 논문은 제안하는 시스템은 u-Health 서비스 중 sensor를 이용하여 원격지 환자의 생체정보를 수집하고, 실시간으로 병원의 클라우드 서버에 전송하는 시스템에서 사용자 검증에 대하여 연구하였다. 여기서 사용자란 클라우드 서버에 접속하는 의사를 말하며, 환자의 생체정보를 보기 위하여 시스템 접속함에 있어 공인인증서나 기타 인증 시스템과 비교해 간편하고, 네트워크 트래픽이 적은 사용자 검증 시스템을 목표로 한다. 그리하여 QRcode를 3개 생성하고, 각 클라우드 서버에 분산 분배 후 서로 섞음으로써 기존의 QRcode와 전혀 다른 인증용 QRcode를 생성할 수 있었다. 이것을 3차원 인덱스를 통해 원본 사용자 QRcode와 대조함으로 사용자 검증 과정을 수행시킴으로써 절차를 간소화하고 네트워크 트래픽을 약 15% 감소시킬 수 있었다.

Purpose: This study aimed to develop the Korean Prototype of Wellness Index (KP-WI) and identify the relationship between Koreans' health characteristics and wellness. Methods: The Wellness Index (WI) was translated into the primitive version of the KP-WI, considering the Koreans' culture and health behavior. It was administered to 223 service industrial employees at one workplace along with the Positive Affect and Negative Affect Schedule (PANAS) and Stress Questionnaire-Short Form. Data analyses included item-total correlation, Pearson's correlation coefficient, independent t-test, and one-way ANOVA. Results: The primitive version was modified to KP-WI based on the item-total correlation. The items considered to lower the reliability of the KP-WI were eliminated. Cronbach's ${\alpha}$ for each subscale ranged from .857 to .939. Perceived stress and negative emotions correlated significantly with wellness measured by KP-WI (r=-.29, p<.001; r=-.27, p<.001). Positive emotions correlated significantly with wellness (r=.60, p<.001). Conclusion: This study contributes to the development of Korean-style wellness indexes by developing a prototype and exploring the factors related to wellness.

A health index was proposed that evaluates personal health state from both measured physiological variables and survey questions. Four health indices were defined such as cardiovascular index, stress index, obesity index, and management index. The total health index was calculated by summing these four health indices. Physiological variables such as blood pressure, heart rate variability(HRV), accelerated photoplethysmograph(APG), and body fat percentage were non-invasively measured and a survey questionnaire that asks personal health state, exercise intensity, and food preference was developed. The suggested health index was applied to thirty eight persons including 30 patients and 8 normal persons with an average age of 51.8. The average health index was estimated to be 75.1 out of 100 points. Young age group(below 50) and men group showed higher health indices than the aged(over 50) and women groups. The correlation coefficient between the cardiovascular index and stress index was found to be 0.513, which means stress is related to cardiovascular health state. The correlation coefficient between the measurements and survey questions was 0.385 for the cardiovascular index. It was as low as 0.182 for the stress index. More case studies may improve correlations between measurements and survey questions, and then, the current health index system may develop as an effective tool to evaluate personal health state.
