  • In this paper, a design of multiple channel wireless remote control system for unmanned vehicle is proposed. One of serious problems of the previous wireless remote control system is that it does not work when a control channel is damaged in case of emergency because it's composed of single control channel. Therefore, we propose the multiple channel wireless remote system which is composed of a portable wireless remote controller and a stationary wireless remote controller. The portable wireless remote controller and stationary wireless remote controller are designed and the multiple channel wireless remote control system for unmanned vehicles in developed. By applying to the unmanned vehicle to check its performance. The wireless remote control system is tested. Emergency stop using the portable wireless remote controller is tested when the stationary wireless remote controller is damaged. Also, emergency stop using the stationary wireless remote controller is tested when the portable wireless remote controller is damaged. The result of emergency stop test shows satisfied performance.

  • Purpose: This study was conducted to identify the effects of educational intervention on pre-test and post-test tidal volume, endotracheal peak pressure, and ventilation interval measurements during single-rescuer respiratory-assistant therapy by paramedic students. Methods: The present study, with a quasi-experimental design, included a pre-test and post-test nonequivalent control group. A total of 62 paramedic students (31, experimental group; 31, control group) participated in this study. The intervention lasted 80 minutes. Data were collected from each student before the intervention and two weeks after the intervention, between September 3 and 21, 2018. The collected data were analyzed using IBM SPSS Statistics for Windows, Version 25.0. Results: Tidal volume (p<.001) and endotracheal peak pressure (p=.002) measurements after the intervention were significantly different between the two groups. Analysis of covariance was used to control the variance (the pretest value of endotracheal peak pressure) in order to identify the effect of the intervention in the two groups. Endotracheal peak pressure was not significantly different between the two groups. Conclusion: Education and training of paramedic students in emergency medical services on single-rescuer respiratory-assistant therapy is necessary for the emergency care of patients with respiratory arrest.

  • In an emergency management case, evaluating the economic value of information technology investments is a challenging problem due to the effects of decision making, uncertainty of disasters, and difficulty of measurements. Risk assessment and recovery process, one of the major functions in emergency management, consists of (1) measurement of damages or losses, (2) recovery planning, (3) reporting and approving budgets, (4) auctioning off recovery projects to constructors, and (5) construction for the recovery. Specifically and of our interest, measurement of damages or losses is often a costly and time-consuming process because the wide range of field surveys should be performed by a limited pool of trained agents. Managers, therefore, have to balance accuracy of the field survey against the total time to complete the survey. Using information technologies to support field survey and reporting has great potential to reduce errors and lowers the cost of the process. However, existing cost benefit analysis framework may be problematic to evaluate and justify the IT investment because the cost benefit analysis often include the long-run benefit of IT that is difficult to quantify and overlook the impact of managerial control upon the investment outcomes. Therefore, we present an alternative cost-centric control model that conservatively quantifies all cost savings to replace benefits in cost benefit analysis and incorporate the managerial control. The model provides a framework to examine how managerial decision making and uncertainty of disaster affect the economic value of IT investments. The current project in Emergency Agency in South Korea is introduced as a case to apply the cost-centric control model. Our work helps managers to better evaluate and justify IT-related investment alternatives in emergency management.

  • Objectives: Emergency medical personnel (EMPs) are pre-hospital emergency responders who are at risk of exposure to infections and may also serve as a source for the transmission of infections. However, few studies of infection control have specifically addressed EMPs in the Republic of Korea (hereafter Korea). The goal of this study was to assess the current status of infection prevention and control programs (IPCPs) for EMPs in Korea. Methods: A cross-sectional survey was conducted to quantitatively assess the resources and activities of IPCPs. A total of 907 EMPs in five metropolitan cities completed a structured questionnaire from September 2014 to January 2015. The data were analyzed using descriptive statistics, multi-response analysis, and the chi-square test. Results: The mean age of the participants was $34.8{\pm}15.1years$. IPCPs were found to have weaknesses with regard to the following resources: the assignment of infection control personnel (ICP) (79.5%), hand hygiene resources such as waterless antiseptics (79.3%), the use of paper towels (38.9%), personal protective equipment such as face shields (46.9%), and safety containers for sharps and a separated space for the disposal of infectious waste (10.1%). Likewise, the following activities were found to be inadequately incorporated into the workflow of EMPs: education about infection control (77.5%), post-exposure management (35.9%), and the decontamination of items and spaces after use (88.4%). ICP were found to have a significant effect on the resources and activities of IPCPs (p<0.001). The resources and activities of IPCPs were found to be significantly different among the five cities (p<0.001). Conclusions: IPCPs for EMPs showed some limitations in their resources and activities. IPCPs should be actively supported, and specific IPCP activities for EMPs should be developed.

  • In this paper, we have developed the system of emergency vehicle preemption signal control based on UTIS(Urban Traffic Information System) which have been deployed and operated in the national capital area. It considered the turning direction(through or left turn) of emergency vehicle at the signalized intersection in order to provide the consecutive progression of emergency vehicle and minimize the control delay of passenger cars. we adopted several EVP control modes such as phase insertion and phase adjustment mode. Also, we evaluated the possibility of field implementation via simulation analysis using CORSIM RTE(Run Time Extension) based HILS(Hardware In the Loop Simulation). We expect that the result of this research contribute to providing the right-of-way to emergency vehicle in this country.
