Purpose: We analyzed the need for home care services and awareness of U-healthcare in nurses of the Catholic Parish Home Care Center to link the ubiquitous health care system and the home care. Methods: We recruited 46 nurses from a home care center in the catholic parish of the C medical center from April 4th to June 8th, 2007. Results: The highest needs were 'assessment and diagnosis of the problem', 'management of hypertension & diabetes patients', 'counseling of the patient', and 'counseling of major caregiver and family problems'. Therapeutic nursing showed the highest needs in bedsore care. Nurses want hospital medical records available through the ubiquitous health care system. Conclusion: Home care services are supported from the agency, with high needs in assessing and diagnosing the problem, counseling, and managing of hypertension & diabetes patients. Education and public relations efforts on the U-healthcare system should improve system awareness.

In this paper, we proposed a multi-agent based healthcare system (MAHS) which is the combination of medical sensor module and wireless communication technology. This MAHS provides wide services to mobile telemedicine, patient monitoring, emergency management, doctor's diagnosis and prescription, patients and doctors, information exchange between hospital workers in a long distance. Also, MAHS is connected to Body Area Network (BAN) and a doctor and hospital workers. In addition, we designed and implemented extended JADE based MAHS that reduces hospital server's burden. Agents gather, integrate, and deliver the collected patient's information from sensor, and provide presentation in healthcare environment. Proposed MAHS has advantage that can handle urgent situation in the far away area from hospital like Islands through PDA and mobile device. In addition, by monitoring condition of patient (old man) in a real time base, it shortens time and expense and supports medical service efficiently.

Adaptive services need to become as mobile as their users and be extended to take advantage of the constantly changing context in which they are accessed. Context-awareness is a technology to facilitate information acquisition and execution by supporting interoperability between users and devices based on users' context. The objective of this study is to develop a middleware fer dealing with context-awareness in ubiquitous computing. To achieve it, our middleware plays an important role in recognizing a moving node with mobility by using a bluetooth wireless communication technology as well as in executing an appropriate execution module according to the context acquired from a context server. In addition, for verifying the usefulness of the Proposed middleware, we develop an application system which Provides a music playing service based on context information by using our context middleware.

As the sensors and communication technology get advance, the remote health diagnosis for patients and senior persons at home are possible now without visiting doctors in hospitals. A low-power ubiquitous health check device was developed adapting Real-Time Embedded Linux is developed. This ubiquitous device is consisted of three sensors. The wrist type health checking terminal acquires periodically the health data by using a blood pressure sensor, a pulse sensor and a body temperature sensor. It transmits the health data to the access point located at the home center through the ZigBee wireless communication modem. This health data collector or access point device sends the data again to the main server operated in a hospital or health care organization. The health server control continuously the input data and sends an alarm signal to the assigned. doctor and responsible persons using cellular SMS when any dangerous events occur. This wrist type health check device has an embedded linux OS using Intel PAX255 MPU. The developed U-Health system is applicable for checking patients health in remote at home. And their family or related persons in remote site can check the patients health status at any time. They can be assured by receiving SMS record and alarm of emergency case which is transmitted from the health server.

A median barrier in the road is to separate driver and passenger the traffic flow in the 4-line over highway. In order to keep thee safety of and minimize the traffic jam in the traffic accidents, the ubiquitous intelligent median barrier system is proposed in this paper. This system is required to develop the sensor node fields in the median barrier, which detects the traffic accident using vibration sensors and wireless communication network. Free space test to sensing & receiving radio frequency, verification of middleware to report and countermeasure the accident intelligently to police and hospital are carried out.

In contrast to the increase in demand for high quality healthcare, there is limited medical human resources such as doctors and nurses so an excessive amount of workload is being forced to them. Therefore, a patient monitoring system using USN(Ubiquitous Sensor Network) is becoming a solution. This paper proposes a patient monitoring system applying USN in maternity hospital to reduce the workload of nurses. According to the efficiency evaluation test based on the model of two university hospitals(S, K University Hospital) and their doctor's diagnosis, the results showed that under the circumstances that one nurse is in charge of 12 patients(6 normal delivery patients and 6 cesarean delivery patients), a total of 1,260 minutes of workload was saved during hospitalization period(5 days). Also, we compared the workload of nurses with or without our proposed system, and the figures showed that in case of normal delivery patients, the workload of nurses decreased by 50 minutes per patient, whereas in case of cesarean delivery patients, the workload of nurses decreased by 130 minutes per patient.

Scedosporium apiospermum, the anamorph of Pseudallescheria boydii, is a ubiquitous saprophytic fungus. S. apiospermum can cause life-threatening infections usually in immunocompromised patients or after near-drowning incidents. Here, we report the first case of disseminated infection caused by S. apiospermum after near-drowning in Korea. A 44-year-old healthy man developed aspiration pneumonia, followed by multiple brain abscesses, and endopthalmitis, after a near-drowning incident in a septic tank. S. apiospermum infection was diagnosed on the 33rd day after the incident had occurred. The patient died from the progressive renal failure 255 days after incident, although he had been treated with voriconazole.

Healthcare is a field where ubiquitous computing is most widely used. We propose a mining-based healthcare multi-agent system for ubiquitous computing environments. This proposed scheme select diagnosis patterns using mining in the real-time biosignal data obtained from a patient's body. In addition, we classify them into normal, emergency and be ready for an emergency. This proposed scheme can deal with the enormous quantity of real-time sensing data and performs analysis and comparison between the data of patient's history and the real-time sensory data. We separate Association rule exploration into two data groups: one is the existing enormous quantity of medical history data. The other group is real-time sensory data which is collected from sensors measuring body temperature, blood pressure, pulse. Proposed system has advantage that can handle urgent situation in the far away area from hospital through PDA and mobile device. In addition, by monitoring condition of patient in a real time base, it shortens time and expense and supports medical service efficiently.

There are rapidly increasing in the number of SNS users according to quick supply of smart phones and expansion of wireless internet services, but there is no much researches on hospital promotion using SNS. In this paper, we proposed methods for development of effective hospital promotion by investigating current status of homepages, mobile web contents and SNS operated in 21 dermatology hospitals located at Seoul city and by analyzing contents according to functions as hospital promotion media. In the investigation results, all of three contents such as homepage, mobile web content and SNS are opened in 76.1% of hospitals and external companies occupied the main management body of the three contents at the largest portion(56.2%). There are hospital information, clinic, reservation in all hospitals' homepages and followed by broadcasting(90.5%), medical treatment(85.7%), consultation information(80.9%), member information in 'mypage'(42.9%), staff information(14.3%). In the analysis results, there is need to enlarge departments or staffs taking full charge of in order to manage the three contents professionally and also there is need to prepare and conduct hospital promotion methods using prevalent SNS.
