유비궈터스 헬스케어는 단일화된 서비스가 아니라 다양한 기술들이 복합적으로 결합되어 운용되는 서비스이다. 따라서 서비스의 형태가 고정적이지 않고 매우 다양하게 나타난다. 하지만 실제로 차이가 발생하는 부분은 서비스의 구현에 관한 세부적 내용에서 나타나고, 서비스 운용을 위한 기본 구성요소에 있어서는 큰 차이가 없이 유사한 형태를 가진다. 그 결과 유비쿼터스 헬스케어 서비스 개발 과정에서는 실제 서비스의 구현 외의 통신과 데이터베이스의 이용, 메시지 전달과 같은 중복되는 항목에 대한 고려가 매번 이루어져야 한다. 이것은 개발 과정에 있어 불필요한 비용의 증가를 불러온다. 본 논문에서는 이와 같은 불필요한 비용을 감소시키며 서비스의 개발과 운용이 가능한 유비쿼터스 헬스케어 서비스의 제공을 위한 아키텍처와 서비스 개발을 위한 프레임워크를 제안한다. 제안하는 서비스 제공 아키덱처는 크게 이용자 단말, 유비궈터스 헬스케어 서비스 센터, 외부 기관으로 구성된다. 서비스 개발 프레임워크는 서버와 클라이언트 프레임워크로 구분된다. 서비스 개발 프레임워크는 서비스를 제공하는 서버에서 필요한 유비쿼터스 헬스케어 서비스의 공통 구성요소를 가진다. 서비스의 개발을 위해 우선 프로세스에 대한 정의를 수행하고, 정의된 내용에 따라 필요한 코드 템플릿을 결합하여 서비스의 초기 형태를 만들어낸다. 여기에 각 서비스가 필요로 하는 세부 사항을 작성하는 것으로 서비스의 개발을 수행하게 된다. 제안된 서비스 제공 아키텍처와 서비스 개발 프레임워크를 실제 적용해보기 위해 전림선비대증 환자 진료를 위한 시스템을 설계하고 구현하였다.JSHOP2 계획수립기내에 구현하였다. 계획 실행 방법으로는 주어진 강건한 계획에 대하여 행위들이 직접 실행하수 있도록 한다.며 용량에 의존하는 양상을 보였다. $H_2O_2$에 의해 유발(誘發)된 DNA의 손상은 catalase와 deferoxamine에 의해 억제되었지만 DPPD는 억제시키지 못했다. 배기음(排氣飮)은 $H_2O_2$에 의해 유발(誘發)된 ATP의 소실을 회복시켰다. 이러한 실험결과 $H_2O_2$에 의해 유발(誘發)된 세포(細胞)의 손상(損傷)은 지질(脂質)의 과산화(過酸化)와는 다른 독립적인 기전에 의해 일어남을 나타낸다. 결론 : 이러한 결과들로 볼 때 Caco-2 세포(細胞)에서 배기음(排氣飮)이 항산화작용(亢酸化作用)보다는 다른 기전을 통하여 Caco-2 세포안에서 산화제(酸化劑)에 의해 유발(誘發)된 세포(細胞)의 사망(死亡)와 DNA의 손상(損傷)을 방지할 수 있다는 것을 가리킨다. 따라서 본 연구(硏究)는 배기음(排氣飮)이 반응성산소기(反應性酸素基)에 의해 매개된 인체(人體) 위장관질환(胃腸管疾患)의 치료(治療)에 사용할 수 있을 가능성(可能性)이 있음을 제시하고 있다.에 이를 이용하여 유가배양시 기질을 공급하는 공정변수로 사용하였다 [8]. 생물학적인 폐수처리장치인 활성 슬러지법에서 미생물의 활성을 측정하는 방법은 아직 그다지 개발되어있지 않다. 본 연구에서는 슬러지의 주 구성원이 미생물인 점에 착안하여 침전시 슬러지층과 상등액의 온도차를 측정하여 대사열량의 발생량을 측정하고 슬러지의 활성을 측정할 수 있는 방법을

The real-time biomedical signal monitoring is a very important factor to realize the ubiquitous healthcare environment. Most of these devices for monitoring the biomedical information get the PPG signal from the user, and these signals are utilized for monitoring their health. It is inconvenient to get the PPG because the user should wear the finger probe with his finger for measuring the PPG signal. Also it is difficult to get the PPG correctly, because of the motion artifacts from the movement of the user. In this paper, we develop the watch type biomedical signal monitoring system without the finger probe, and propose the new algorithm for reducing the motion artifacts from the PPG signal. We designed the system which gets the PPG from the sensor on the wrist band strip. As compared with the finger probe type, this system we proposed is more affected by the motion artifacts. So to filter this motion artifacts, we propose the new method; the improved PMAF(Periodic Moving Average Filter) method.

The metallothionein (MT) gene (IbMT3) was selected from an EST library of suspension-cultured sweet potato cells. The MT gene, which is one of abundant ESTs in the library, is involved in stress regulation of cells and tissues. A full-length IbMT3 cDNA was obtained and analysis of its nucleotide sequence revealed that IbMT3 encoded a type 3 MT protein, based on its structural characteristics. The function of type 3 MT in plants is not yet known. Northern blot analysis showed stronger expression of IbMT3 in suspension-cultured cells than in sweet potato plant leaves. Since cell culture is known to impose a state of oxidative stress on cells, sweet potato plants were subjected to oxidative stress to investigate the transcriptional regulation of IbMT3. When the herbicide methyl viologen (MV) was administered for 6, 12, and 24 hr, IbMT3 transcription rapidly increased at 6 hr and then decreased. A cold treatment at $15^{\circ}C$ for 24 and 48 hr resulted in a gradual increase in IbMT3 expression. These findings indicate that IbMT3 expression is regulated in response to environmental and oxidative stress. IbMT3 isoform is expected to have antioxidant effects in sweet potato plants and may play an important role in cellular adaptation to oxidative stress.

As the ubiquitous technology has penetrated into almost every aspect of modern life, the research of the security technology to solve the weakness of security in the ubiquitous environment is received much attention. Because, however, today's security systems are usually based on the fixed rules, many security systems can not handle diverse situations in the ubiquitous environment appropriately. Although many existing researches on context aware security service are based on ACL (Access Control List) or RBAC (Role Based Access Control), they have an overhead in the management of security policy and can not manipulate unexpected situations. Therefore, in this paper, we propose a context-aware security service providing multiple authentications and authorization from a security level which is decided dynamically in a context-aware environment using FCM (Fuzzy C-Means) clustering algorithm and Fuzzy Decision Tree. We show proposed model can solve typical conflict problems of RBAC system due to the fixed rules and improve overhead problem in the security policy management. We expect to apply the proposed model to the various applications using contextual information of the user such as healthcare system, rescue systems, and so on.

In this paper, we propose a ubiquitous $SaO_2$ monitoring system for patients using oxygen therapy. For these patients, the ability to monitor oxygen saturation ubiquitously is very important fur accurate adjustment of ventilator's flow rate to match the patient's time-varying requirements with the shortest lag time possible. We have developed a portable device to measure $SaO_2$ and transmit it to hospital in real-time or in store-and-forward mode through the integration of $Bluetooth^{TM}$ technology and the code division multiple access (CDMA) cellular network. We also developed software for doctors to receive and manage the patients' $SaO_2$ information. Performance of the developed system was evaluated as acceptable by assessing the accuracy of the measured oxygen saturation value and the stability of communication network. Test results in real clinical setting demonstrate that our system is feasible for immediate use in home oxygen therapy.

Objectives : The purpose of this study was to propose the utilization plan of Ryodoraku in the U-health care systems. Methods : Computerized literature searches were performed for Ryodoraku related articles using the following databases: KISS, RISS, DBPIA, NDSL from 1990 to Oct 2010. Search terms were '양도락' or 'Ryodoraku' or 'U-health'. Due to Ryodoraku coming from Japan, additional literature review(articles published by 2008) on Japanese journal of Ryodoraku medicine was done for compensation. Results : 1. Introduction of U-health : As rapid progress of population aging and strong interest in health, the demand for the traditional Korean medical service is increasing. Until now healthcare service has provided post treatment by face-to-face manner. But according to related researches, proactive treatment is resulted to be more effective for preventing diseases. Particularly, the existing healthcare services have limitations in preventing and managing chronic geriatric degenrative diseases such as metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis, etc., because the cause of the above is complex and even related to life habit. As the advent of ubiquitous technology, patients with the chronic geriatric degenrative diseases can improve life habit such as poor eating habits and physical inactivity without the constraints of time and space through u-healthcare service. Therefor, lots of researches for u-healthcare service focus on providing the personalized healthcare service for preventing and managing that. To cope with this situations, The concept of u-healthcare service should be adopted in the traditional korean medicine and diagnostic devices suitable for it should be also devised and developed based on traditonal korean medine. 2. Review of existing Ryodoraku related articles for applying to U-health : articles investigating feasibility applying Ryodoraku to meridian diagnosis and raising problems of it, articles providing recent research trends of Ryodoraku, Ryodoraku related articles considering usefulness for U-health, and articles confirming the repeatability and reproducity of Ryodoraku were included. Based on the review of the above Ryodoraku related articles, several application of Ryodoraku in the U-health care system. Conclusions : To make preparations for the increasing need of traditional Korean medicine due to rising morbidity rate of chronic geriatric degenerative diseases, it is necessary to appropriately apply Ryodoraku to the U-health care system. The application of Ryodoraku is as follows. 1. To use Ryodoraku additionally to the established diagnostic device of metabolic syndrome, CVA, coronary heart diseases, parkinson's diseases, degenerative joint disease, spondylosis. 2.
