Recently there are some trends to construct smart home system infrastructure depending upon the development of Information and Communication Technology. Also requirements of the Ubiquitous Healthcare Systems at home which can monitor the status of health continuously are increased rapidly comparing with hospitals. Healthcare service can be divided into two categories. The first one is Alarm Service that can be used for the emergency status and the other one is Remote Support Service which can monitor the patient including home environments and give those diagnosis information to medical office or to his family. Generally wired networks and fixed healthcare measuring system have some limits to transmit reliable realtime based information for both categories described above comparing with portable monitoring system. Getting over the inefficiency we will design and implement portable healthcare system under the wireless Zigbee network environments.

The X-ray unit developed by this study is to diagnose emergency cases which is too far from a hospital and to classify the patients. We have to use the X-ray in a ambulance or the scene of an accident where we cannot use the AC220 outlet because of the distance from a hospital as well. The X-ray unit developed has a characteristics as follows. First of all, as the unit has a condenser in itself where there is no electric supply, we can use the X-ray inspector in a mountain area or a island. Second, we can detect by digital detector the information taken by X-ray from DC 12[V] electricity and store as a form of file. A control circuit can secure the reliability of the X-ray unit by using the Pic16F84A X-ray and provide various functions. The X-ray unit which suits remote emergency system can be efficiently used for the emergent cases who is too far from a doctor and a hospital or in the situation where it is difficult to diagnose, transcribe and treat simultaneously.

본 연구는 스마트폰 사용자가 응급상황에 처했을 때 사용자의 정확한 위치 정보를 응급 구조 센터에 전달할 수 있는 방법을 개발함에 목적을 둔다. 사고의 경우 실외 뿐만 아니라 실내에서 많은 사고가 발생하는데, 일반적으로 위치 정보를 획득에 사용되는 GPS 의 경우는 실내 위치를 정확하게 파악하기 어렵기 때문에 구조를 지연시키는 문제를 야기한다. 본 연구는 이러한 상황들을 방지하기 위해 GPS와 와이파이, 블루투스를 각각 이용한 삼각 측량법을 통해 실내의 위치정보를 측정하고 더 나아가 압력센서를 통해 사용자의 위치를 3차원적으로도 탐색한다. 실험 결과, GPS를 이용하는 것보다 블루투스를 이용하는 것이 더 정확한 실내 정보를 탐색하는 것을 알 수 있었다. 또한 압력계를 통해 고도를 측정함으로써 건물 내부에서 사용자의 수직적 위치를 측정할 수 있었다. 이러한 결과는 위도 경도의 정확한 정보와 함께 고도에 대한 예측을 가능하게 함으로써 보다 정확한 실내 위치 정보를 획득하여 골든 타임을 확보하는데 도움이 될 것으로 보인다.

Purpose: Prompt arrival of emergency vehicles at the scene is important. Therefore, special cases for emergency vehicles are being applied. However, there remain obstacles that obstruct the prompt arrival during dispatch. Methods: First, a literature review revealed five categories of problems with the emergency vehicle priority signal system. Then, the first Delphi survey was conducted to confirm the validity of the five categories. Further, a second Delphi survey was conducted to identify additional problems, and we used a 5-point Likert scale for a third Delphi survey. Results: A total of 92 items were extracted from preceding studies. The validity of the five categories was confirmed in the first Delphi survey. Then, 123 additional items were derived from the second Delphi survey, and the final 50 items were selected from 93 items obtained from the third Delphi survey. Conclusion: This study revealed problems and improvement measures for improving the operation of the emergency vehicle priority signal system that were not proposed in previous studies.

Lone Death is increasing as elderly population increases. Lone elderly is vulnerable in society for many reasons. This paper explores digital solution to protect solitary in society. First, sensor and AI care robot can be used to collect digital data and situation check. Second, digital device is checked regularly and visiting is expanded in digital environment. Third, digital emergency security system should be established. Fourth, user education is to be regularly carried out including complementary education.

U-healthcare is real-time monitoring of personal biometric information using by portable devices, home network and information and communication technology based healthcare systems, and fused together automatically to overcome the constraints of time and space are connected with hospitals and doctors. As u-healthcare gives health service in anytime and anywhere, it becomes to be a new type of medical services in patients management and disease prevention. In this paper, recent changes in prevention-oriented care is analyzed in becoming early response for Healthcare Information System by requirements analysis for technology development trend. According to the healthcare system, PACS, OCS, EMR and emergency medical system, U-healthcare is presenting the design of a patient-centered integrated client system. As the relationship between the meaning of the terms is used in the ontology, information models in the system is providing a common vocabulary with various levels of formality. In this paper, we propose an ontology-based system for patient-centered services, including the concept of clustering to clustering the data to define the relationship between these ontologies for more systematic data.

When an applicant requests the emergency situation call or safe return service using a smart device, the smart surveillance service can select the CCTV(closed circuit television) cameras around the applicant using applicant's location information, then automatically takes a photograph to track the applicant. Since the surrounding CCTV camera shoots the applicant continuously using location information and the applicant can be observed by the monitor agent in real time, this service can be very helpful in an applicant's emergency situation or safe return. The existing smart surveillance service does not consider the priority of the emergency situation call and safe return service. Therefore, there is the disadvantage that the applicant who requests an emergency situation call service can not be photographed when safe return service has already preoccupied CCTV cameras which are capable of taking a picture of the applicant. The proposed smart surveillance service improves this disadvantage by using service priority.

의료기관의 응급실은 환자의 생명을 다루는 긴박한 현장으로 환자에 대한 실시간 모니터링 및 관리가 필수적으로 요구되는 곳이다. 본 연구에서는 기존 응급실 진료 프로세스를 체계적으로 관리하고 모니터링 하기 위해 BPM 아키텍처를 도입하여 응급실 업무들을 표준화, 가시화함으로써 의료진의 신속한 응급 업무 대응이 가능한 응급신속대응관리시스템(EQRMS-Emergency Quick Response Management System)를 제안한다. 의료기관에서 BPM의 도입은 단순히 병원 경영 목표나 병원 내외부의 운영을 모니터링 할 수 있는 이점 이외에 병원 업무의 이윤을 극대화 할 수 있는 다양한 효과가 있다. 또한 임상위험수치 (CV-Critical Value)를 정의함으로써 복잡한 검사의 단순화와 검사 시간 단축, 검사의 오류 발생률 감소 등 환자의 안정성 제고 측면에도 크게 기여할 것이다.
