The concern regarding inability to perform CPR properly was widespread, and few studies, however, have queried bystanders regarding their responses to an actual emergency. This study assessed how often CPR was performed by CPR-trained bystanders and what factors were associated with the performance and nonperformance of CPR by trained bystanders. From a 2,000 sample survey of the National Emergency Medical Center in Korea (2008), it extracted object persons who actually experienced an emergency situation, and examined closely the relationship of CPR education experience and CPR performance in an emergency. 169 completely interviewed, 23(13.6%) had CPR education experience and performed CPR in an actual emergency, 40(23.6%) had CPR education experience but didn't performed, 12 (7.1%) didn't have CPR education experience but performed, and 94(55.6%) neither had CPR education experience nor performed. Specifically, within bystanders who had CPR education experience, those who CPR was performed were different from those who CPR was not on medical emergency-related characteristics such as CPR knowledge(p=0.001), 1339 emergency phone number(p=0.006) and 1339 emergency services(p=0.001). Consequently, to consider social characteristics or an economic condition, various CPR teaching strategies should be prepared to continuously propel.

With the development of IT technology recently, medical information systems are being constructed in an integrated u-health environment through cloud services, IoT technologies, and mobile applications. These kinds of medical information systems should provide the medical staff with authorities to access patients' medical information for emergency status treatments or therapeutic purposes. Therefore, in the medical information systems, the reliable and prompt authentication processes are necessary to access the biometric information and the medical information of the patients in charge of the medical staff. However, medical information systems are accessing with simple and static user authentication mechanism using only medical ID / PWD in the present system environment. For this reason, in this paper, we suggest a dynamic situation authentication mechanism that provides transparency of medical information access including various authentication factors considering patient's emergency status condition and dynamic situation authentication system supporting it. Our dynamic Situation Authentication is a combination of user authentication and mobile device authentication, which includes various authentication factor attributes such as emergency status, role of medical staff, their working hours, and their working positions and so forth. We designed and implemented a dynamic situation authentication system including emergency status decision, dynamic situation authentication, and authentication support DB construction. Finally, in order to verify the serviceability of the suggested dynamic situation authentication system, the medical staffs download the mobile application from the medical information server to the medical staff's own mobile device together with the dynamic situation authentication process and the permission to access medical information to the patient and showed access to medical information.

Modern society is facing an unstable environment due to unexpected accidents and hazardous situations. For example, incidents such as the collapse of the Bundang Bridge and the crushing accident in Itaewon could serve as examples. In addition to these, critical emergencies like sudden cardiac arrests and strokes frequently occur, requiring swift actions and smooth transfers to specialized medical institutions for effective responses. In response to these risks, the country has been establishing various systems to protect the lives and safety of its citizens. Among these, the 119 First Aid Activities plays a crucial role within the emergency medical system. Its goal is to promptly respond to critical emergency situations involving severe trauma patients or patients with serious illnesses, minimizing damage and safeguarding lives by swiftly transferring them to emergency medical institutions for specialized treatment. The core activity related to this is emergency rescue operations. In particular, the 119 First Aid system serves as a crucial institution responsible for the hospital transportation of emergency patients. However, rescue personnel still encounter cases of interference with their activities during their duties. Despite efforts from the police, these interference cases persist, and they share similarities with the crime of obstructing official duties. Interference with emergency activities exhibits a comparable nature to instances such as physical assaults and equipment damage against emergency medical practitioners working within the emergency medical system. Therefore, a comprehensive understanding and improvement efforts regarding the issues of interference that arise during the process of emergency medical activities, including the 119 First Aid system, are necessary. The solution to these problems is to establish and improve the conditions for obstruction of first aid activities, focusing on the "Framework Act on Firefighting" and the "Act on 119 Rescue and Emergency."

Direct medical control by medical doctors is an essential part of emergency medical services system (EMSS). However, the indications are not specifically defined, even in 119 system with their own medical control team. The Seoul Metropolitan Fire and Disaster Management Department has operated internal medical consultation services on its own since January 2004. Based on the experiences from these services, we reviewed the cases of the direct medical consultation and establish the indications for direct medical control. And we presumed the demand of direct medical control with the established indications. The crews of 119 in Seoul made 793 calls to Medical Control Team during November 2004. We reviewed all of the calls according to the level of consciousness (AVPU), the kinds of emergency care done by crews during transport (10 categories), and the mechanisms of injuries (9 categories). The need for direct medical control was judged by authors with reviewing the records reported by the crews and control teams. Among 23 items, 14 items assigned as the indications, which were abnormal level of consciousness (VPU), 6 kinds of emergency care, and 5 mechanisms of injures. The sum of the three of them, 7,782 cases (45.9%), was in need of direct medical control. In conclusion, about half of the patients transported by 119 crews in Seoul require direct medical control. The need for the direct medical control in Seoul was estimated as many as 260 calls per day. To fulfill the need for direct medical control and to provide a effective medical control, the direct medical control should be accomplished through the communications between the crews and the medical staffs in the local hospitals.

Recently, the environment of a hospital information system is a trend to combine various SMART technologies. Accordingly, various smart devices, such as a smart phone, Tablet PC is utilized in the medical information system. Also, these environments consist of various applications executing on heterogeneous sensors, devices, systems and networks. In these hospital information system environment, applying a security service by traditional access control method cause a problems. Most of the existing security system uses the access control list structure. It is only permitted access defined by an access control matrix such as client name, service object method name. The major problem with the static approach cannot quickly adapt to changed situations. Hence, we needs to new security mechanisms which provides more flexible and can be easily adapted to various environments with very different security requirements. In addition, for addressing the changing of service medical treatment of the patient, the researching is needed. In this paper, we suggest a dynamic approach to medical information systems in smart mobile environments. We focus on how to access medical information systems according to dynamic access control methods based on the existence of the hospital's information system environments. The physical environments consist of a mobile x-ray imaging devices, dedicated mobile/general smart devices, PACS, EMR server and authorization server. The software environment was developed based on the .Net Framework for synchronization and monitoring services based on mobile X-ray imaging equipment Windows7 OS. And dedicated a smart device application, we implemented a dynamic access services through JSP and Java SDK is based on the Android OS. PACS and mobile X-ray image devices in hospital, medical information between the dedicated smart devices are based on the DICOM medical image standard information. In addition, EMR information is based on H7. In order to providing dynamic access control service, we classify the context of the patients according to conditions of bio-information such as oxygen saturation, heart rate, BP and body temperature etc. It shows event trace diagrams which divided into two parts like general situation, emergency situation. And, we designed the dynamic approach of the medical care information by authentication method. The authentication Information are contained ID/PWD, the roles, position and working hours, emergency certification codes for emergency patients. General situations of dynamic access control method may have access to medical information by the value of the authentication information. In the case of an emergency, was to have access to medical information by an emergency code, without the authentication information. And, we constructed the medical information integration database scheme that is consist medical information, patient, medical staff and medical image information according to medical information standards.y Finally, we show the usefulness of the dynamic access application service based on the smart devices for execution results of the proposed system according to patient contexts such as general and emergency situation. Especially, the proposed systems are providing effective medical information services with smart devices in emergency situation by dynamic access control methods. As results, we expect the proposed systems to be useful for u-hospital information systems and services.

Influenza is an infectious disease caused by an influenza virus with symptoms of high fever and headache. Since influenza especially mutates into multiple subtypes in the carrier's body, it is a serious threat for mankind such as Spanish influenza. The treatment of influenza infection mandates the use of antiviral drugs through rapid diagnostic test. Generally, immunochromatography-based rapid influenza diagnostic tests are used for rapid diagnosis in an emergency. In this paper, we propose an influenza analysis algorithm based on image processing to examine a large number of patients suspected of being infected with influenza. Also, we propose a robust influenza analysis algorithm based on the joint cumulative mass function under varying radiometric conditions such as illuminant and exposure differences. Simulation results show that the proposed algorithm significantly reduces the error of influenza diagnosis under different radiometric conditions.

In medical Institution, Electronic Health Record (EHR) is "must access information" to medical staff considering it as medical information. However, this unnecessary exploration of personal information must be treated confidentially because the information is highly related to other's private concerns. It is necessary that medical workers should be also restricted to their access to EHR depending on their roles and duties. As the result, this article explains that "EHR access control will be executed by differentiating authorized medical staff from non medical-related staff as well as EHR access will be only permitted to authorized medical staff depending on their work status conditions. By using Advanced RBAC model on medical situation, we expect to minimize unnecessary leak of EHR information; especially, emergency medical care is needed, access control is highly required depending on a person in charge of the cases or not, and restricted medical information defined by the patient one-self is only allowed to be accessed.
