In mobile healthcare service, the accurate detection and the notification of the emergency situation are important to chronic patients' life. In the existing healthcare service, the medical staff or medical service provider always judges patients' health status by monitoring from the measured from bio-data. However, it is difficult to monitor many patients in real-time simultaneously, because the medical staff should monitor the health status continuously. Furthermore, an emergency condition diagnosis based solely on the statistical level of the bio-data may be difficult, since the emergency judgment of the bio-data might differ depending on the health characteristics of each person such as age, history of disease, gender, etc. In order to solve this problem, this article presents an mobile healthcare system for emergency bio-data management using a personalized emergency policy. The salient feature of the proposed mobile healthcare system is that the characteristics of the health status of an unique patient is defined to the policy, which is used to judge the emergency condition of the bio-data measured from the patient. The prototype of proposed mobile healthcare system has been built to demonstrate the design concept.

We proposes a new approach for testing the self visual-acuity by using the KS standard optotype. The proposed system provides their hand-gesture recognition method for the convenient response of subjects in the visual acuity measurement. Also, this system can measure a visual-acuity that excludes the examiner's subjective judgement or the subject's memorized guess, because of presenting a random optotype automatically by computer without a examiner. Especially, Our system guarantees the reliability by using the KS standard optotype and its presentation(KS P ISO 8596), which is defined by the Korea Standards Association in 2006. And the database management function of our system can provide the visual-acuity data to the EMR client easily. As a result, Our system shows the 98% consistency in the limit of the ${\pm}1$ visual-acuity level error by comparing the visual-acuity chart test.

The quality control is needed to ensure the accuracy of medical information and achieved by evaluating the performance of and maintaining the system and practicing various measurements and evaluations. The Korean Institute for Accreditation of Medical Image, therefore, have held educational program for quality control of special medical equipments. The major of programs participants, however, are radiology specialists with only small number of radiological technologists from some hospitals, furthermore, the follow-up education and the share of information between participants and non-participants are insufficient in general, thus, the knowledge level of radiological technologists, regardless of their participation, is relatively low. This study carried out the questionnaire research for the 500 radiological technologists registered in Korean Society of MRI Technology, on the basis of 2008, and performed analysis for five months from May to Oct., 2008. The questionnaires were delivered by post to each radiological technologists and the response rate was 36%(n=180). The results of this revealed that the 86.7% of respondents felt the necessity of inspection on quality management, while only the 27.8% completed the educational program for manager of special medical equipment. and only the half(53.9%) had the knowledge about inspection on quality management. The completion of educational program had no correlations with sex, age, size of occupying hospital, the number of radiological technologists in occupying site and MRI laboratory, career year of general radiologist and in MRI laboratory, and the presence of biomedical engineering department in occupying hospital. The 78.0% of participants at the educational program for quality management held by the Korean Institute for Accreditation of Medical Image had the knowledge about inspection on quality management(p<.05) whereas the 43.9% of the hospitals held such program and the 54.4% of radiological technologists from those hospitals had related knowledge, which indicated that such programs held by hospitals had not effects on the knowledge level of radiological technologists. This indicates also that the contents, methods, and other conditional factors of educational programs are important for the outcome of them.

The aim of this study was to examine fluid excretions and changes in deceased bodies depending on type, location of, and causes of death for hygienic management of funeral homes. Based on the 858 cadavers studied, the average age at the time of death is 68.6 years, 83.0% had illness as the cause of death, and 79.5% passed away in a medical facility. Fluid excretion was observed in 46.2% of the cadavers. In manner of death, 78.8% of deaths -highest percentage- was due to an accident and 10.8% of deaths - lowest percentage- was due to age. Fluid excretion was observed in 46.3% of cadavers from medical facilities, 38.6% of cadavers from homes and 77.4% of cadavers from miscellaneous locations. There were various number of cadavers with recorded immediate, secondary and underlying cause of death; however, the fluid excretion rate was similar. In analyzing the immediate, secondary and underlying cause of death, respiratory and heart disease were the most common causes of death in categories of body organ and system. In terms of fluid excretion, liver disease followed by digestive and circulatory diseases were most common in immediate cause of death. Accidents and miscellaneous circumstances were most common amongst secondary and underlying causes of death for cadavers with fluid excretion. Based on the recorded illnesses of the cadavers, cardiopulmonary failure was most common as evident in 96 cadavers followed by pneumonia and sepsis. Cholangiocarcinoma (73.3%) had the highest rate of fluid excretion followed by pancreatic cancer, severe brain injury and liver cancer amongst categories of illnesses with more than 15 cadavers.

IT technology of U-healthcare system is being grafted onto medical services and the use of U-healthcare system are extending steadily. However, in case of patients using Implantable Medical Device (IMD) in U-healthcare system, patients' privacy protection and safe access to system recently has emerged as a major issue. This paper proposes a patients' privacy protection protocol to prevent any illegal accesses from third parties as state value and action value are synchronized after patients' information virtualization. The proposed protocol can limit the access range of patients' information according to authentication information of hospitals, doctors, nurses, and pharmacies registered in the U-healthcare server. Additionally, this protocol can increase management efficiency for patients' privacy by synchronizing state values and action values only for approved information and, by instituting this process, third parties cannot easily access patients' information.

전문가시스템은 지식베이스를 이용하여 지식을 추론하는 추론엔진과 해당분야의 전문지식이 쌓여있는 지식베이스로 구성되어진다. 전문가시스템연구에 있어서 지식베이스에 저장되는 지식획득과 정의 규명이 가장 핵심적인 연구분야하고 할 수 있다. 전문지식은 일반적으로 지식공학자들이 전문가로부터 전문지식을 획득하여 구현하는 것이 가장 일반적인 방법으로서 많은 전문가시스템 개발방법 이론들은 지식획득과정에서 지식공학자들의 역할을 필수적인 것으로 이해하고 있다. 그러나 지식획득에 관한 광범위한 해결책은 여전히 제시되고 있지 못하며, 이러한 문제점은 전문가 시스템의 상용화에 가장 큰 어려움으로 지적되고 있다. 최근에는 이러한 지식획득병목현상을 해결하기 위하여 상황인식론과 같은 지식에 대한 새로운 해석을 기반으로한 지식획득 방법 이론들이 소개되고 있다. Multiple Classification Ripple Down Rules 이론은 1995년 소개된 이론으로서 지식의 획득과정을 지식의 유지보수라는 소프트웨어 공학적 개념에서 접근하고 있다. 지식의 획득과정에서 완전무결한 지식의 모델 찾기를 지양하고 지식이란 단계적 확장개념에서 진화한다고 이해한다. 즉 지식베이스의 구축 단계를 개발과 완료가 불가능하다는 관점에서 지식베이스 끊임없이 유지보수가 필요한 대상으로 이해하고 이러한 유지보수를 가능하게 하는 방법론을 제시한다. MCRDR에서 가장 핵심적인 부분은 지식공학자의 역할을 최소화하고 시스템 내부에서 지식의 관리와 획득을 수행하여 연구실험을 통하여 실용성이 입증되었고 의료분야에서 상용화 시스템 개발 툴로서 사용되어져 왔다. 그러나 MCRDR 이론이 적용된 전문가시스템들의 경우 MCRDR이론을 기본으로한 개발 툴로서 개발된 시스템들이 아니고 해당분야에서 MCRDR이론을 적용한 엔진을 직접 설계 구현하여 온 것이 사실이다. KEE(Knowledge Engineer for Experts) 시스템은 최근 개발된 MCRDR기반 전문가시스템 개발 툴로서 본 논문에서는 이러한 분야별 전문가시스템 개발을 지양하고 MCRDR 이론을 기반으로 한 범용성 있는 전문가시스템 개발 툴의 개발에 관한 연구를 소개한다.
