Recently, with the development of IoT, AI, and mobile terminals, medical information platforms are expanding. The medical information platform can determine a patient's emergency situation, and medical staff can easily access patient information through a mobile terminal. However, in the existing platform, emergency situation decision is delayed, and faster and stronger authentication is required in emergency situations. Therefore, we propose an edge computing-based medical information platform for automatic authentication using patient situations. We design an edge computing-based medical information platform architecture capable of rapid transmission of biometric data of IoT and quick emergency situation decision, and implement the platform data flow in emergency situations. Relying on this platform, we propose the automatic authentication using patient situations. The automatic authentication protects patient information through patient-centered authentication by using the patient's situation as an authentication factor, and enables quick authentication by automatically proceeding with mobile terminal authentication after user authentication in emergencies without user intervention. We compared the proposed platform with existing platforms to show that it can make quick and stable emergency decisions. In addition, comparing the automatic authentication with existing authentication showed that it is fast and protects medical information centered on patient situations in emergency situations.

Recently, introduction of the hospital information system has remarkably improved the efficiency of health care services within hospitals. Due to improvement of the hospital information system, the issue of integration of medical information has emerged, and attempts to achieve it have been made. However, as a preceding step for integration of medical information, the problem of searching the same patient should be solved first, and studies on patient identification algorithm are required. As a typical case, similarity can be calculated through MPI (Master Patient Index) module, by comparing various fields such as patient's basic information and treatment information, etc. but it has many problems including the language system not suitable to Korean, estimation of an optimal weight by field, etc. This paper proposes a method searching the same patient using MRI information besides patient's field information as a supplementary method to increase the accuracy of matching algorithm such as MPI, etc. Unlike existing methods only using image information, upon identifying a patient, a highest weight was given to physical information of medical image and set as an unchangeable unique value, and as a result a high accuracy was detected. We aim to use the similarity measurement result as secondary measures in identifying a patient in the future.

기존의 환자 모니터링 시스템은 환자가 자신의 정보를 원하는 경우 의료 기관을 통해서 정보 확인이 가능 하였다. 그러나 U-Healthcare 기반의 환자 모니터링 시스템에서는 RFID 시스템을 의료 환경에 적용하여 언제 어디서나 자신의 정보를 RFID 리더가 탑재된 모바일 장치를 통하여 확인이 가능하다. 환자의 태그 정보를 읽어 들여 환자가 원하는 서비스를 제공하기 위해서는 RFID 미들웨어 설계가 필요하다. 임베디드 리눅스 기반의 RFID미들웨어는 크게 RFID 모듈, ARM 프로세서, RS-232 인터페이스 등으로 구성된다. RFID 모듈은 사용자의 정보를 입력받기 위하여 사용되며, RS-232 인터페이스를 통하여 RFID 미들웨어로 정보를 전달한다. 또한 본 시스템은 임베디드 전용 ARM 프로세서를 사용하여 환자 모니터링 시스템에 특화된 시스템을 구현하였다. 본 논문에서 제안한 U-Healthcare 기반의 환자 모니터링 시스템은 임베디드 리눅스 기반의 Qt를 사용하여 RFID 미들웨어를 구현하였다.

Medical technology is gradually being developed by applying information technologies. Especially, RFID technology is being used for precise disease history information of patients [4]. And in case the patient is far away, the patient can be treated using network communication of the internet [5][6]. The internet makes us to treat or operate the patient without being restricted to time or space. If the above technologies are made as a system, the patient can be treated or operated without being restricted to time or space. In this paper, we present a patient treatment system has been implemented with a system using RFID and network communication of the internet [1][2][3][4]. The system is driven as follows. First, the information of patient can be checked from a remote PC, if the tag that a patient has been read through a reader. And a remote treatment is performed by controlling robot's arm with a joystick using internet network [19][20][21]. The RFID system was implemented in frequency of 125 KHz [1]. The information of patient can be checked with PDA, PC and C-LCD using Bluetooth and WLAN [7][8][9][10]. For the treatment and operation of the patient, the robot's arm has been formed using AX-12 motor, joystick and two buttons [11][12][13][14][15] [17][18].

Purpose: Despite growing interest in health information sharing, researchers remain uncertain whether hospitals' sharing of information increases patient satisfaction, one of the key measures of the quality of care. This study evaluates the effect of health information sharing on patient satisfaction and whether the effect varies with context. Methodology: Regression analysis was conducted using a sample consisting of 6,641 year-hospital observations, based on data from the annual and IT surveys of the American Hospital Association (AHA) and Census. Findings: Our results suggest that information sharing using health IT increases patient satisfaction, while the extent (breadth) of information sharing increases patient satisfaction, the level of detail (depth) of information sharing does not. Our results also show that the effects of the breadth and depth of information sharing vary with different contexts, e.g., the percentage of people over 65 and Hirschman-Herfindahl index (HHI). Practical Implications: Policymakers should pay greater attention to realizing the full benefits of hospitals' information sharing based on market characteristics.

The purpose of this study is to build a database of patient information for efficient radiotherapy management. Microsoft Office Access was used to build the database owing to its convenience and compatibility. The most important aspect when building the patient database is to make the input and management of patient information efficient at every step of radiotherapy process. The information input starts from the patient's first visit to the radiation therapy department and ends upon completion of the radiotherapy. The forms for each step of radiotherapy process include the patient information form, the radiotherapy schedule form, the radiotherapy information form, the simulation order form, and the patient history form. Every form is centrically connected to the radiation oncology department's patient information form. A test revealed that the database was found to be efficient in managing patient information at each step. An important benefit of this database is improved efficiency in radiotherapy management. Information on patients who received radiotherapy is stored in a database. This means that this clinical data can be found easily and used in future, which will be helpful in research studies on the radiation oncology department. Benefits such as these will potentially contribute to improved radiotherapy quality.

USN(Ubiquitous Sensor Network)는 환자의 생체 정보를 실시간으로 수집하고 수집된 정보를 DB(Data Base)에 저장을 한다. DB에 저장된 환자의 생체 정보는 환자가 자주 이용하는 병원에 저장되어 환자가 병원을 이용 할 경우 저장되어 있는 환자의 생체 정보를 가지고 진료를 하게 된다. 하지만 저장되어 있는 위치는 병원 내의 서버나 PC 환경에 저장을 해놓고 있기 때문에 환자가 다른 병원을 이용하게 될 경우 기존 병원의 DB에 요청을 해야 한다. 하지만 기존 병원은 보안, 인증, 관리, 비용, 인력 등의 문제가 있기 때문에 다른 병원과의 정보 교환이 쉽게 이루어지지 않는 문제가 있다. 그래서 환자의 생체 정보가 환자의 모바일 기기에 저장 되어 있는 경우 그대로 사용할 수 있다는 장점이 있다. DB는 정보를 빠르고 정확하게 찾는 것이 중요하다. 본 연구에서는 환자 중심의 서비스를 위한 모바일 순환 Loop DB 시스템을 연구한다.

본 논문에서는 헬스 케어 시스템에서 효율적으로 질병을 관리할 수 있는 RDMS(Rough Set Theory based Disease Monitoring System)을 제안한다. RDMS는 DCM(Data Collection Module), RDRGM(RST based Disease Rule Generation Module), HMM(Healthcare Monitoring Module)로 구성된다. DCM은 바이오센서로부터 환자의 생체 정보를 수집하고, 데이터 처리 절차에 따라 RDMS DB에 저장한다. RDRGM은 RST의 코어와 속성의 지지율을 이용하여 질병 규칙을 생성한다. HMM은 DCM에 의해 수집된 환자 정보를 이용하여 환자의 질병에 대한 위험지수뿐만 아니라 질병에 대한 합병증에 관한 위험지수까지 분석함으로써 환자의 질병을 예측하고, 환자의 위험지수에 따라 환자, 주치의 등에 시각화된 환자의 정보를 전달한다. 또한, RDRGM에 의해 생성된 규칙들에 따라 환자의 의료정보, 현재의 환자건강상태, 환자 가족력 등을 비교분석하여 환자의 질병을 예측하고, 예측결과에 따라 환자 맞춤형 의료 서비스와 의료 정보를 신속하고 신뢰성 있게 제공할 수 있다.

In this paper, we investigate the patient fall prevention system to prevent the patient from falling out of the bed unintentionally on the bed of the bed. Patients stay in bed for many hours of hospitalization. During the hospitalization period, patients have low controllability of the body, as compared with normal persons, and fall due to intentional movements, resulting in a fall of the patient, can be a fatal threat to the patient. Therefore, an efficient fall prevention system is required. In this paper, the distance map to the patient is generated by the distance measuring sensor on the bed of the patient, and the risk is determined by estimating the position of the patient based on the distance map. As a result, when the distance map of the dangerous area is 150 mm or more, it is determined to be dangerous, and good results are obtained.
