Most recent birth rate at home raising children, only one has come out well. Accordingly, children born to parents is to have a strong interest, and healthcare (Healthcare) sector, while emerging as a new growth industry (Baby Care) Baby Care also increased the interest. Baby Care products until now the food, toiletries and clothing, etc. Although it advances the development of ubiquitous computing environment with the development of the healthcare industry, Baby Care Electronics products have been developed. Europe and the U.S. infant from another room deungeseoneun feeder. At this time SIDS infants to prevent this phenomenon often takes place in order to measure the status of children and away from parents to children, also can check the status of children was used to implement the Platform. In this paper, using the radio frequency real-time observation of data storage without the parents were determined only by the speed of the ARM11-based systems using the S3C6410 CPU and wireless WI-FI (IEEE8.2.11) technology to prevent sudden infant death using Platform for the implementation study was conducted.

For the possible application of monitoring or diagnosing heart sounds in an ubiquitous healthcare environment. a small and light electro-stethoscope that can be attached in human body should be exploited. With this aim, this study proposes a new style of electro-stethoscope device that is composed of four hardware modules in wearable style. For this ambulatory heart sound collecting device, the several tests must be performed to check portability and material capability for collecting heart sounds. It turned out to be that the multi-channel electro-stethoscope can detect heart sound signals well even if it is not pinpointed in the accurate stethoscope point on a heart. Consequently, our ambulatory electro-stethoscope hardware system can be applied to monitor or diagnose abnormal heart sounds in the ubiquitous healthcare system.

In this paper, the module for measuring SpO2 and PPG(Photo Plethysmo Graphy) signal of human body and the module for wireless communication of these bio-signals to PC were developed. The program was developed to display transmitted SpO2 and PPG signal by various type data and graph without information loss during a emergency transfer. This system can be utilized as appropriate for remote medical care and a new market is expected, to be created according to revision of medical law.

An integrated security mechanism is one of the key challenges in the open wireless network architecture because of the diversity of the wireless network in open wireless network and the unique security mechanism used in each one of these networks. In the paper we analysed some elements to guarantee security and privacy preserving in distributed IT applications which provide some kind of support to complex medical domains.

Recently, Healthcare system has not been standardized and has been developed as an embedded system lacking interoperability. We are finally going to face such problems as having excessive load in using network caused by the uncontrolled spread of system and un-guaranteed interoperability among the heterogenous systems. We suggest the possibility that OSGi (Open Service Gateway initiative : the international standardization of service middleware) can be accepted as a solution for the above problems.

In comparison with a existing passive Healthcare system, a healthcare system applied OSGi framework is spontaneous and excellently expandable. But, OSGi-based healthcare system has security vulnerability which OSGi has the technical feature and restriction in the service support area. In this paper, in order to overcome these vulnerability, we propose the technique that applies JXTA standardized P2P platform in OSGi-based healthcare system.

The use of Radio Frequency Identification technology (RFID) in medical context enables not only drug identification, but also a rapid and precise identification of patients, physicians, nurses or any other health care related staffs. The combination of RFID tag identification with structured and secured Internet of Things (IoT) solutions enables ubiquitous and easy access to medical related records, while providing control and security to all interactions. This paper surveyed a basic security architecture, easily deployable on mobile platforms, which would allow to establish and manage a medication prescription service in mobility context making use of electronic personal health records.

일반적으로 출생 후 1세 전후의 영유아들은 신체의 발달이 온전치 않아 수면중 질식사하는 영유아 돌연사증후군(SIDS)에 이를 수 있어, 보호자의 세심한 관심이 필요하다. 더욱이 보호자가 있더라도 오히려 더 높은 질식에 의한 사망률이 늘어나고 있다. 이를 위해서, 본 논문에서는 수면시 발생할 수 있는 질식사 방지를 위한 하드웨어 장치와 이와 연계된 스마트폰 앱(App) 시스템을 설계하고 구현한다. 제안된 시스템으로써 하드웨어 장치는 초음파 거리 센서(sonsor)를 이용하여 실시간으로 뒤집힘 여부의 정보를 수집하여 무선 통신을 통해 스마트폰 앱(App)에 전달한다. 또한 스마트폰 앱 시스템은 수집된 정보를 분석 판단하여, 비정상적인 상태의 영유아에 대해 긴급 경보와 긴급 전화를 자동 호출한다. 따라서 여러 위험에 노출되어 있는 영유아들의 수면중에 뒤척이다 엎드려 자는 경우, 호흡기를 막거나 가슴압박으로 인한 질식사를 미연에 방지한다. 향후, 본 논문에서 제안된 시스템은 졸음방지나 낙상방지시스템 같은 유비쿼터스 헬스케어(ubiquitous healthcare) 환경 구현에도 적용될 수 있다.

In this paper, we implemented a heartbeat-signal monitoring system that can measure and check the heartbeat of a human body in any time and anywhere. The implemented prototype is composed of heartbeat measurement terminal, gateway, and server that collect and process data. The terminal compose sensor network using ZigBee protocol. And server acquire heartbeat signal through differentiating collected data two times, and store above data to database and manage it. We can understand the status of examinee's heart without restriction and self-awareness. Through experiment, we confirmed the possibility of ubiquitous healthcare system based on sonsor network using the ZigBee.
