한국전력거래소는 전력계통의 안정적, 경제적 운영을 담당하고 있는 기관으로 '01년 현재의 에너지관리시스템(EMS)를 도입하여 실시간 전력계통에 대한 정확한 판단을 기반으로 전력계통의 안정성과 경제성 확보에 주력하고 있다. '06년 EMS S/W를 자체 유지 보수하기로 전력거래소 정책이 결정됨에 따라 상주 유지 보수 업체 인력이 철수하여 IT운전원 1명이 모든 감시 업무를 수행해야만 했다. 이에 따라 업무가 가중되고 효율적인 감시 체계가 만들어질 수 없는 상황이었다. EMS의 1차적 감시는 EMS 자체제공 감시 화면을 통해 가능했으나, 이는 수동적이고 다단계 절차가 필요한 비효율적인 작업이다. 1인에게 집중되어 있던 이러한 감시 작업을 간소화하고 체계화시키기 위하여 분산되어 있던 감시 요소들을 그룹화하고, One-sight 감시가 가능하도록 통합시키는 시스템을 제공하는 것이 거래소 IT 업무의 이슈가 되었다. 본고에서는 이러한 니즈에 따라 개발된 EMS 종합감시시스템에 대해 소개하고자 한다.

최근 전력 수요가 지속적으로 증가함에 따라서, 전력 수급을 관리하는 EMS 에 대한 관심이 높아지고 있다. 전력 수급을 안정적으로 관리하기 위해서는 전력 계통의 상태변화에 따라 급전원에게 실시간 알람을 발생시켜주는 알람 시스템이 반드시 필요하다. 그러나 기존 EMS 의 알람 시스템은 알람 인지자의 역할을 고려하지 않고 알람 발생 여부를 알려주고 인지함으로써 보안상의 문제점을 가지고 있다. 본 논문에서는 RBAC 기반의 EMS 알람 시스템을 제안한다. 제안된 시스템을 통해 EMS 의 알람 시스템은 허가된 급전원에게만 알람 발생 여부를 알려주고 알람을 수신한 급전원이 직접 알람을 인지하도록 한다. 또한, 수신한 급전원이 원거리에 위치할 경우, 근거리 급전원에게 알람의 인지를 위임함으로써 알람 시스템의 보안을 강화한다.

Purpose: To analyze trends related to demography and EMS and to provide supporting data for the appropriate deployment of EMS providers. Methods: In this cross-sectional study, data on patients transported by 119 EMS, demographics, and EMS factors were collected using the Korean Statistical Information Service (KOSIS) and the National Fire Agency annual report from 2017 to 2021. Results: During the study period, the total number of patients and those with severe disorders transported via 119 EMS showed an increasing trend. The total fertility rate and population during the same period tended to decrease, and the population density and number of households increased; however, there was a disparity between regions. The main demographic factors affecting the number of patients transported were population density and total fertility rate, while the main EMS factors were the number of ambulances and provision of emergency medical information services(hospital guidance, pharmacy information, and first aid guidance). Conclusion: From the perspective of EMS providers' force deployment, it is necessary to consider population density, population, number of households, total fertility rate, and number of emergency medical institutions and to strengthen the role of diverting the use of 119 EMS by minor patients by providing emergency medical information.

In Korea, the number of LPG vehicles is increasing continuously because LPG is cheaper than Gasoline. Also in Europe, the CNG fuel is a good solution to meet $CO_2$ regulation. In order to use LPG/CNG fuel, new EMS ECU must be developed for every type of vehicles and it requires huge development cost. In order to reduce development cost and time, SIEMENS VDO has developed an Interface Box. It supports EMS ECU in the car and manages LPG/CNG fuel injection system. Basically the Interface box can be used with any kind of EMS ECU. The Interface Box controls LPG/CNG injector through the injection command of gasoline EMS ECU. It calculates required amount of based on the fuel temperature and pressure and sends feedback signal to ECU for fuel correction. Also, it controls LPG/CNG specific actuator such a Shut off valves and LPG switch inputs.

The purpose of EMS is to provide emergency patients with prompt and suitable emergency treatments therefore it saves their lives and makes them recover fast to return to normal. The purpose of correctional administration is to return inmates to society as sound citizens after their service by providing various correctional education, reformational programs, vocational training and etc. In this way, the aim of correctional administration and EMS is like mutual agreement by their returning to society safely. Therefore this study makes some propositions like the followings for the safety between many inmates who can have physical injury and exposure to diseases caused by particularity of subculture within correctional institutions and the staffs who work for them. It is said about efficient pre-hospital EMS through various causes of emergency situation in the correctional institution, system, manpower, facility, equipments and problems and so on. 1. Recruit the first-rate EMT(emergency medical technician) as central role of pre-hospital EMS according to each correctional institution and working terms. 2. Equip specialized transference system with symptom of patients and purpose of transference. 3. Emergency medical equipments and first-aid medicines should be equipped for field and ambulance. 4. Educate correctional officers as first responders and inmates within correctional institutions about systematic emergency treatment.

With the emergence of the smart grid era, the interest in green energy which reduce carbon emissions and environment-friendly smart grid which combines the advantages of power and IT technology is increasing around the world. To use the smart grid effectively heterogeneous systems such as EMS, MOS and WIS must be linked together. However, additional interface should be developed to link EMS and heterogeneous systems since IEC has only defines the interface for EMS. Especially, to link legacy system and new system, some software might need to be designed and developed because separate interfaces for connection can be developed depending on each system and environment. In this paper, we propose an integrated interface based on CIM for interconnection between systems. A proposed interface can integrate messages of heterogeneous system and will be able to reduce costs that could be incurred by the removal of the existing system and the addition of the new system.

Analysis methods in the power system are static analysis, dynamic analysis and online analysis, offline analysis. The static analysis is used for the existing power system analysis method and the static analysis is mainly used for PSS / E. However, in the real system where the value changes in real time which we are using, dynamic analysis is required which can be analyzed in real time for accurate analysis. Therefore, attention is focused on EMS (Energy Management System) and importance is increasing. Among the various EMS systems, we will cover state estimation, which is a static on-line analysis that can receive and interpret data from the acquisition point in real time. DC systems are spreading in various fields such as DC load, DC distribution, renewable energy. As such, much attention and attention are focused on the DC system. In this paper, we have studied the feasibility through the case study and the interpretation of the state estimation that can be applied to the DC system.

Emergency Medical Service(EMS) requires a system that supports the communication between emergency medical technicians (EMT)s and the doctor in the emergency department. Because the rapid triage and on-site treatment of patients need doctor's medical advice. However, a system to assist the doctor assign for medical advice does not exist in Korea. This paper suggests a medical advice support system that focuses on appropriate doctor assign and real-time communication among the ambulance, the Emergency Medical Information Center (EMIC), and the doctor using an agent system. We expect that the system can help to solve the problems affecting prehospital EMS and improve its general quality.

In this paper, we analyzed two methodologies to evaluate the total quality management activities comparatively. One of them is the traditional scoring system (TSS) by analytic hierarchy process (AHP) and the other is the efficiency measuring system (EMS) by data envelop analysis (DEA), It is demonstrated that the index by TSS and the efficiency index by EMS are not correlated. Also, the efficiency index by EMS in terms of company characteristics such as the size of company and ISO certifications is different from the index by TSS. The result implies that to evaluate the quality activities by EMS is needed as a supplementory methodology.
