The present sensor network technology is rapidly developing with advent of diverse sensors and operating systems, and diverse application technologies using sensor network technology are being presented; out of them, a signature technology is a context awareness application adjusting movement by recognizing a context. The field of context awareness application serves as a wide variety of application service by recognizing users’ location through sensor and processes location information in diverse forms, and one of the most important application fields is a health care field. The u- Healthcare makes it possible to monitor a patient’s condition in a remote manner by using a wide array of medical appliances and sensors to provide health management and medical service. This enables service to be offered to even remote regions where medical service is hardly conducted, and emergency situations to be taken care of through real – time monitoring. The u- Healthcare system can offer health management and a wide range of medical service to the elder living alone not given appropriate medical service. Thus, the research herein is conducted on the u- Healthcare system that can transmit a patient’s emergency situations and location information at the same time as it is embedded with diverse sensors to detect emergency through a patient’s bio sign als examined. Delivering clinic information of patient at the point-of-care to physicians is critical to increase the quality of healthcare services, especially in emergency departments of hospitals. However, since that medical records and clinic data are distributed in different hospitals, it is sometimes difficult to collect clinic data of patient ubiquitously in case of urgency. In order to support the ubiquitous content accessing, in this paper, a resource model is first proposed to locate and get clinic data which are stored in heterogeneous hospital information systems. Then, a ubiquitous clinic data accessing method is proposed based on the resource model. In the proposed method, clinic data of patient is defined as resource with unique URL address. Related clinic data of one patient is collected together to form a combinational resource, and could be accessed by physician if authority is assigned to the physician. Finally, case study is discussed to illustrate the method of clinic data accessing through Internet from different healthcare units. The result shows that the clinic data of patients could be accessed more conveniently. Cloud computing is an “emerging paradigm” in the field of Information Technology for scalable, internet based, real time applications and resources to satisfy end users’ needs. This state-of-the-art technology is utilized in vital healthcare services to incorporate emerging applications such as remote patient monitoring, electronic health record and collaborative consultation. In this paper the system plans to propose the architecture of a cloud-based healthcare application intending to serve patients in emergency conditions. A centralized cloud database would hold individual’s medical history in a single summarized document. In case of any accident or emergency situation, the patient’s previous medical history can be retrieved from the cloud database before starting any crucial operation. This system can also be integrated with state owned unique identification number systems. In this paper, the system are study conducted on the u-Healthcare system that can transmit a patient’s emergency situations and location information at the same time as it is embedded with diverse sensors to detect emergency through a patient’s bio signals examined.
