Every year, the complexity and scale of disasters are growing. Cooperation between institutions must occur in order to adequately respond to urgent situations caused by these disasters. However, agencies and institutions tend to operate separately, which impose limitations to an integrated disaster response. To combat this problem, the subject of this study: 'Korean standardized integrated response system For disaster site' proposes to develop a response system that is applicable to disasters of all types and scales. Standard Formation, SOP (Standard Operation Procedure), and Standard Terms have been developed to be applicable to various institutions and agencies. The necessity for legal and institutional support to actualize the standardized system is focused on. Utilizing a standardized integrated response system will enable a unified command and control structure at disaster sites, clarify each institution's response tasks, and allow clear and efficient communication among response entities. Ultimately, these benefits will improve efficiency and performance in disaster response efforts.

This paper deals with a control technique of eliminating the transient vibration with respect to a waist axis of an articulated robot. This control technique is based on a model-based control in order to establish the damping effect on the driven mechanical part. The control model is composed of reduced-order electrical and mechanical parts related to the velocity control loop. The parameters of the control model can be obtained from design data or experimental data. This model estimates a load speed converted to the motor shaft. The difference between the estimated load speed and the motor speed is calculated dynamically, and it is added to the velocity command to suppress the transient vibration. This control method is applied to an articulated robot regarded as a time-invariant system. The effectiveness of the model-based control integrated into the position control loop is verified by simulations. Simulations show satisfactory control results to reduce the transient vibration at the end-effector.

An integrated EIA tool was developed to analyze present and future environmental quality status of Youngwol Basin using ArcView and FEMWASP. All the input data and computational results were prepared and graphically displayed on the basis of ArcView. FEMWASP and ArcView were integrated using the command "system.execute" in script of Avenue. Modeling items were inserted in the GUI of ArcView. The modeling result showed that the water quality of the proposed Yougwol Lake would be at the stage of eutrophication. The developed system can be applied to the water quality management of drinking water resources to set up the regulatory acts and project plan of governmental policy.

The current trend of low cost ultra-small satellites is to utilize Commercial Off the Shelf (COTS) parts to save cost, and accordingly, Command and Data Handling (C&DH) that operates the satellite and collects/processes the data is also designed and developed around commercial controllers. However, functionalities of commercial controllers are limited according to the specs outlined by the manufacturer. In order for the commercial controllers to be used for satellites where variety of interfaces is required, a separate interface circuit is required. Therefore, a Multi Digital Data Control System (MDDCS) using Field Programmable Gate Array (FPGA) has been developed in order to expand multiple digital interfaces that are not supported by the commercial controller, and also to compensate for SEU. This has been implemented on Actel A3P1000 using Very High Speed Integrated Circuits Hardware Description Language (VHDL).

The defense system development process is a process of developing various systems that perform functions in various functional areas such as battlefield awareness, command control, force application, and logistical support. In other words, the defense system development process is a process of developing many systems simultaneously in various functional areas. Various systems developed through this process should be interoperable so that they can be integrated and operated in a joint warfighting environment. To successfully implement this, the US Department of Defense uses the Joint Capability Integrated Development System(JCIDS) for the defense system development, and within this JCIDS processes the Capability Based Assessment(CBA) methodology as its core technology. This CBA methodology transforms the mission activity requirements to functional capability requirements logically and transforms the functional capability requirements to system requirements logically also. Smart City is a city that improves the convenience and quality of life of the citizen by integrates various systems that perform various functions of the city and smarties various functional systems with smart services by using IT technology. In other words, defense system development and smart city development have a common feature of the process of developing many systems simultaneously in various functional areas. In order to address the problem of having to develop many systems simultaneously in each functional area, it is important to logically transform the various mission scenarios into functions and logically transform the functions into systems. Therefore, a joint capability integrated development system and its core methodology, Capability Based Assessment(CBA), can be applied to smart city development. This paper proposes a method for performing a smart city concept design method using the capability based evaluation (CBA) method.

Recently, with the rapid development of eXtended Reality(XR) technology, the development and use of education and training systems using XR technology is increasing significantly. In particular, in areas that involve great risks and high costs such as military training and counter-terrorism training, the use of XR based simulators is preferred because they can improve training performance, reduce training costs, and minimize the risk of safety issues that may occur in actual training, by creating a training environment similar to actual training. In this paper, we propose a plan to build and evaluate an XR based hyper-realistic counter-terrorism education, training, and evaluation system to improve the ROK police's ability to respond to terrorist situations using the 5G and AR based Integrated Command and Control Platform previously developed by the Korea Military Academy. The proposed system is designed to improve counter-terrorism capabilities with virtual training for individual and team units based on hyper-realistic content and training scenarios. Futhermore, it can also be used as a on-site command and control post in connection with a simulation training site and an actual operation site.
