Purpose: The purpose of this study was to identify the level of perception of safety risk factors and the degree of performance of safety nursing activities in order to develop an education program to improve the safety of patients. Methods: The subjects were 217 nurses from 3 university hospitals in Incheon. Data were collected with structured questionnaires and analyzed using descriptive analysis, t-test, and ANOVA using SPSS 22.0. Results: The level of perception of patient's safety risk factors and safety care activities was 2.93 and 4.68, respectively. Perception of patient safety risk factors which belonging to the risk type of therapeutic devices, equipment, service and infrastructure all scored below average; also in addition, behavior, performance, and violence risk type and work system, information and communication risk type showed relatively low perception levels. Safety nursing activities showed a low level of performance in accurate communication among medical teams, management of fire and disaster, security management, use of restraints, identification of patients, and correct performance of operations and procedures. Conclusion: Based on these results, it is necessary to improve the safety of patients by taking proper management measures along with education.

This study was carried out to examine the effect of the presence of non-structural walls in apartment buildings subjected to an earthquake. It was believed that the presence of non-structural walls, which has not been considered in the structural design process, was usually built together with structural walls and this led to significant damages to the apartment buildings in Pohang earthquake, 2017. In this study, a 22-story apartment building was selected and modeled to simulate the seismic behavior due to earthquakes. The story drift, performance point, and compressive strain in the walls were the main parameters to evaluate the seismic performance with the presence of non-structural walls.

Ad hoc network does not need any preexisting network infrastructure, and it has been developed as temporal networks in the various fields. Infostation is an efficient system to transfer information which does not have delay sensitive characteristics. In this paper, we propose a disaster emergency management system using sensor attached animals' mobility combined with infostation system. We also analyze the performance of the proposed system by simulation. From the performance analysis results, we expect that the proposed system will be very useful to early detect big forest fires which occurs frequently in Korea mountain areas.

Among various retrofitting strategies, use of semi-active control for retrofitting a building structure has gained momentum in recent years. One of the techniques for such retrofitting is to connect a weaker building to an adjacent stronger building by semi-active devices, so that performances of a weaker building are significantly improved for seismic forces. In this paper, a ten storey weaker building is connected to an adjacent stronger building using magneto-rheological (MR) dampers, for primarily improving the performance of the weaker building in terms of displacement, drift and base shear. For this, a fuzzy logic controller is specifically developed by fuzzyfying the responses of the coupled system. The performance of the control strategy is compared with the passive-on and passive-off controls. Pounding Mitigation between the two buildings is also investigated using all three control strategies. The results show that there exists a fundamental frequency ratio between the two buildings for which maximum control of the weaker building response takes place with no penalty on the stronger building. There exists also a fundamental frequency ratio where control of the weaker building response is achieved at the expense of the amplification of the stronger building. However, coupling strategy always improves the possibility of pounding mitigation.

A core device of foam system is the in-line eductor and it is the device to mix the foam liquid into liquid solution proper to the use density and the mixture ratio must be kept regularly regardless of changing fluid condition of the front and rear end of the in-line eductor. However, if the flux of the pressurized water changes, the mixture ratio is not kept regularly, and so it becomes a cause which a performance of fire-extinguishing deteriorates in discharging foam liquid. I devise a method to improve it that the metering orifice type in-line eductor is improved into the metering venturi type in-line eductor, the fluctuation of the mixture ratio to the flux change of the pressurized water is minimized and the performance of fire-extinguishing is kept regularly. As this method is simple in its structure and can be designed at a low cost, it helps for maintenance as well. In the future, it seems to need the research for the metering nozzle type in-line eductor in the future.
