As the use of unmanned aerial vehicles increases, in order to expand the operability of the unmanned aerial vehicle, it is essential to develop an unmanned aerial vehicle traffic management system, and to establish the system, it is necessary to analyze the integrated navigation performance of the unmanned aerial vehicle to be operated. Integrated navigation performance is affected by various factors such as the type of unmanned aerial vehicle, flight environment, and guidance law algorithm. In addition, since a large amount of flight data is required to obtain high-reliability analysis results, efficient and consistent flight scenarios are required. In this paper, a flight scenario that satisfies the requirements for integrated navigation performance analysis of rotary and fixed-wing unmanned aerial vehicles was designed and verified through flight experiments.

Integrated Pollution Prevention and Control(IPPC) has become an idealistic environmental prevention concept in developed countries and corresponds with principles of Industrial Ecology. The concept of emissions regulatory integration is a key factor for an integrated environmental management system. While most EU member countries have a cross-media regulatory system, Korea has a media-specific regulatory system which was found to have significant environmental management problems. The purpose of this study is to integrate the emissions regulatory system by resolving difficulties through procedural, organizational, and substantive analysis of integration. To this end, the following research was performed: The first task was to determine the target of the integrated emissions regulatory system. In connection with this, the "IPPC directive" of the EU and the "PPCA 2000" schedule 1 of the UK, as well as environmental laws in Korea were compared and analyzed. The second was to design a regulatory system model. This model was divided into three groups after considerations were made regarding the time it would take for the pre-application,application, and permission stages. Lastly, on the basis of this research, a revised bill for an integrated emissions regulatory system was suggested. Nevertheless, substantive analysis of integration focused on BAT requires supplementation in order to make the integrated emissions regulation system operate normally as an environmental management policy and regulation method. To this end, the specific characteristics of Korean society, culture, and law should be actively considered.

Number of researches on efficient terminal operation system applying RFID(Radio Frequency Identification) are on progress. However, RFID has limitations on tracking and providing accurate positions of containers. In this paper, to enhance the performance of the integrated terminal operation system, an efficient loading management of yard is proposed by applying RFID-based RTLS(Real Time Locating System) that provides real-time accurate positions of containers. We found that a group-based sequence system is more efficient than the existing individual sequence number system in the container yard. In the group-based sequence system, the containers in the same group should have similar characteristics such as port of destination(POD), size, weight, etc. In order to run this system, we have proposed the parameters to the unspecified N bytes of RFID tag which are specified in ISO 18000-7. And, this paper proposed a development of integrated operation system of container terminal using RFID for reducing the ship turnaround time in ubiquitous port environment.

Initial prevention activities and rapid propagation conditions is the most important to prevent diffusion of water pollution. If water pollutants flow into streams river or main stresm located in environmental conservation area or water intake facilities, we must predict immediately arrival time and the diffusion concentration to the proactive. National Institute of Environmental Research developed water pollution incident response prediction system linking dam and movable weir. the system is mathematical model which is updated daily. Therefore it can quickly predict the arrival time and the diffusion concentration when there are accident of oil spills and hazardous chemicals. Also we equipped with mathematical model and toxicity model of EFDC(Environmental Fluid Dynamics Code) to calculate the arrival time and the diffusion concentration. However these systems offer the services of an offline manner than real-time control services. we have ensured the reliability of data collection and have developed a real-time water quality measurement data transmission device by using the data linkage utilizing a mode bus communication and a commercial SCADA system, in particular, we implemented to be able to do real-time water quality prediction through information infrastructure of the water quality integrated management business created by utilizing the construction of the real-time prediction system that utilizes the data collected, the Open map, the visual representation using charts API and development of integrated management system development based on web maps.
