In this paper we proposed the remote control system for the door lock by the unified modem with the wireless and the power line modem. We developed the management system program between the door-lock system and the proposed unified modem. The infrared communication system was used between the Door-Lock system and the power line modem. With the unified developed modem and the Door-Lock system, it is possible to control remotely the developed system in the internet service area.

In this paper, new results for perturbation bounds for unified decentralized systems by a unified approach using $\delta$ (defined as a shift operator at unified approach) are presented. Robust stability analysis of unified decentralized system is investigated by new robust stability bound under system uncertainties. New unified stability bounds are developed based on the unified Lyapunov matrix equation. It is shown that the system maintains its stability when new unified bounds are applied. Numerical example is presented to illustrate the proposed analysis.

This paper aims to make a step-by-step strategy to formulate an unified health system by clarifying and overcoming challenges facing South and North Korea and to estimate costs needed for South Korea to assist North Korea to recover to normal health delivery system. We explored implications through literature review and estimated costs under the assumption that supportive activities be provided for 5 years in three ways: support for the development of health and medical care manpower; support for health and medical facilities; and support for the provision of both preventive and primary health care. Step-by-step strategy is formulated for a unified health system with the cost estimation resulting as follows: in case of basic scenario, a total of 3 trillion and 341 billion won (at present value of the year 2017) is in need for the 5-year period at the initial 'recovery support stage' with 135.9 billion won for the development of health and medical care manpower, approximately 2 trillion won for health and medical facilities, and 1.2 trillion won for the provision of both preventive and primary health care. Step-by-step approach is more realistic and applicable in formulating unified health system. Suggested stages are 'recovery support stage,' 'system homogenization stage,' and 'unified system stage.' Strategies at 'recovery support stage' suggested in this paper need to be pursued and followed by those at 'system homogenization stage' and 'unified system stage.'

A novel UPQC(Unified Power Quality Conditioner), which consists of series inverter, shunt inverter, distributed generation system, is proposed. The proposing system can compensate reactive power, harmonics, voltage sag and swell, voltage interruption etc. through the change of paralleling operation mode and islanding operation mode. The control strategy for the proposing system was derived using the instantaneous power method. The performance of proposing system was analyzed by means of the PSCAD/EMTDC simulation and the experimental work with the hardware prototype. The proposing system has the ultimate capability of improving power quality at the point of installation on power distribution systems or Industrial power systems and can be utilized for the custom power device in th future distribution system.

This paper describes an advanced unified communication system. The advanced unified communications mean a service that integrates basic communications such as call, SMS, email, and chatting with social networking service considered as a new communication channel, presenting a unified user interface. The advanced unified communication system is composed of advanced UC(Unified Communications) applications, open UC service platform, and UC back-end servers. The advanced UC applications consist of web-based application and smart phone application. The open UC service platform provides a variety of service components that enable the third party applications to access basic communications and social network services within an enterprise. The UC back-end servers provide server functionalities for call, SMS, email, and chatting.

This paper presents a methodology for the application of Unified Modeling Language (UML) to develop the new load management system. Development of new load management system in competitive electricity market is very complex since it requires too much data of power system. For the efficient and flexible design to develop of new load management system, a UML approach in applied which is composed of a class diagram, package diagram using Rational Rose Unified Process.

In order to meet the users demand, who needs faster and more accurate data in geographic information it is necessary to obtain and process the data more effectively. Now more effective data obtainment about geographic information is possible through the development of unified technology, which is applied to the field of geographic information, as well as through the development of hardware and software engineering. With the fast and precise correction and update, the development of unified technology can bring the reduction of the time and money. For the obtainment of geographic information which can meet the demand of the users, the unified technology has been applied to various fields, and in Aerial Photogrammetry field, many are doing researches actively for the GPS/INS unified system. To obtain fast and precise geographic information using Aerial Photogrammetry method, it is necessary to develop Airborne GPS/INS unified system, which makes GCP to the minimum. For this reason, this study has tried to develop a system which could unite and process both GPS and INS data. For this matter, code-processing module for DGPS and OTF initialization module, which can decide integer ambiguity even in motion, have been developed. And also, continuous kinematic carrier-processing module has been developed to calculate the location at the moment of filming. In addition, this study suggests a possibility of using a module, which can unite GPS and INS, using Kalman filtering, and also shows the INS navigation theory.
