For many past years, research in the operation of stand-alone Microgrid, which provides electric power generated from renewable energy sources and energy storage system instead of diesel generators, has been a major issue in order to prepare the exhaustion of fossil fuel and to protect environment, in island grids. Samso Island, known as the world's first stand-alone Microgrid in Denmark, is connected to the mainland grid through AC system, which has different technical conditions with Korea's isolated power system. Korea's first stand-alone Microgrid has been built in Ga-sa island, Chun-la-nam-do, based on Energy Management System (EMS) operation, and other islands are under construction to follow the next step. These stand-alone Microgrid's has large capacity of Battery Energy Storage System (BESS) and the proportion of the renewable energy sources are large, which makes it necessary to use a Microgrid-Energy Management System (MG-EMS) to operate the grid effectively and economically. However, since the main subject of MG-EMS is different from EMS, specific characteristics and functions must be different as well. In this paper, the necessary characteristics and functions are explained for a general MG-EMS compared to a large power system EMS.

Purpose. Based on the comparison and analysis with those of United States, the aim of this research is to find the problems in current management, operation and future directions of emergency medical service (EMS) fund in S. Korea and to provide basic resources and appropriate measures to make a right decision in policies for EMS fund. Methods. Data from Ministry of Health and Welfare and other various sources during 1995 to 2012 were collected and analyzed. Results. From our analyses, several problems are identified in EMS fund operation. In brief, problems discerned are as follows. First, whereas the purpose and direction of EMS fund operations in United States are highlighted and focused on pre-hospital EMS system and associated infrastructures which need to be constructed, those of S. Korea are emphasized mainly on the in-hospital EMS system so far. Second, on the contrary to the fact that the EMS funds in United States are tuned to pre-hospital EMS system to provide prompt and efficient emergency care at the emergency scene of pre-hospital stage and to achieve the development, design, planning and demonstration projects for pre-hospital EMS systems, up to date, our investment of EMS funds demonstrated an excess biased inclination toward the construction of in-hospital EMS system, which is far from the realization of constructive and vital pre-hospital infrastructures. Third, while emergency medical technician is important and principal body in the management of emergency medical funds in United States, so far, no EMS funds in S. Korea existed for EMTs including the job condition, improved treatment and working environment for them. Conclusion. In conclusion, we strongly suggest that the problems pointed out must be revised and corrected. Current usage of EMS fund needs to be redirected predominatly to pre-hospital EMS system. Otherwise, unless current management and investment of emergency medical funds in S. Korea are applied and used for the vital necessities and demands of EMTs, public EMS units and private EMS units as well as related units in pre-hospital EMS system as in the cases of United States, in our consideration, they must be suspended or abolished.

This paper presents the improved zero power levitation control algorithm for a quadruple hybrid EMS (Electromagnetic Suspension) system. Quadruple hybrid EMS system is a united form of four hybrid EMS systems one on each corner coupled with a metal plate. Technical issue in controlling a quadruple hybrid EMS system is the permanent magnet's equilibrium point deviation caused by design tolerance which eventually leads to a limited zero power levitation control that only satisfies the zero power levitation in one or two hybrid EMS system among the four hybrid EMS system. In order to satisfy a complete zero power levitation control of the quadruple hybrid EMS system, the proposed method presented in this paper adds a compensating algorithm which adjusts the gap reference of each individual axe. Later, this paper proves the stability and effectiveness of the proposed control algorithm via experiment and disturbance test.

This paper summarizes a data modeling for developing the baseline network analysis software of the Korean energy management system (EMS). The study is concentrated on the following aspects. First, the data for operating the each application software are extracted. Some of the EMS network application softwares are selected for basis model. Those are based on the logical functions of each software and are not considered the other softwares. Second, the common data are extracted for equipment model and topological structure of power system in Korea. We propose the application common model(ACM) that can be applied whole EMS network application softwares. The ACM model includes the hierarchy and non-hierarchy power system structure, and is connected each other using the direct and indirect link. Proposed database model is tested using the Korea Electric Power Corporation(KEPCO) system. The real time SCADA data are provided for the test. Through the test, we verified that the proposed database structure can be effectively used to accomplish the Korean EMS system.

In Korea, EMS Fund Operation seems to move the opposite direction to right way. The most initial EMS fund was consumed loan for some emergency patients without any particular results. Since 2002, the use of EMS fund also has shown a tendency to shift one side. By the results, it was 44.3% to support emergency medical centers, so called hospital EMS system and 28.4% to purchase ambulances and helicopters, and 1.6% to operate Central Medical Center, prehospital base in the EMS fund consumed in 2004. It was never supported for the environmental improvement and development of universities, colleges, and private EMS units having the primary responsibilities. The initial EMS fund using should be used for prehospital base, e.g., prehospital staffs, communications, and facilities and balanced development between public and private EMS units than any other fund using.

The purpose of this study was to improve EMS-System in Korea through the research in EMS-System of advanced country. The response time is defined as the interval from the time of call receipt to the time of scene arrival. The important factor was to shorten moving distance of ambulance. It should be considered to accomplish this factor that the vehicle must be increased and the convenient location chosen for optimizing of service area. The transport of emergency patients carried out almost by 119 Emergency Medical Service but out of all the employees at 119 EMS only 11.3% have own qualified EMT degree. They should be employed more and more specially at 119 EMS for a superior level of emergency medical care for civilian. In America, EMT can take care of emergency patients following the order from medical Director at the scene of accident. But in Germany, prehospital care was emphasized from the beginning and, in those days, a medical doctor was sent for treatment of emergency patients at the scene, the so-called a Rendezvous system. Hierby this study makes the suggestion to improve the EMS-System, it is effective to use the medical Director system in America and furthermore a Rendezvous system in Germany. The functional integratin and unification of the report system as well as enough personal and equipmental elements saved together invaluable lives.
