경관조명은 야간관광자원 활성화를 통한 대외 경쟁력을 강화하고, 도시경쟁력을 향상시키며, 관광객들에게 도시 브랜드를 전달할 수 있는 수단으로 중요시되고 있다. 본 연구는 경관조명의 활성화에 따른 유지관리 비용을 절감할 수 있는 방안을 검토하기 위하여 국제 조명위원회(CIE)에서 제시하고 있는 조도 및 휘도 기준을 조사하였으며, 한강상 교량과 일산호수공원의 일부 지역에 대한 경관조명 설치현황 및 전력요금 사용실태를 조사하였다. 또한 '조명연출방법'과 '조명자재 선정에 의한 방법'에 따라 유지관리 비용 절감 현황을 검토하였으며, 각 회로를 세분화 하여 시간대별 제어가 가능하도록 하고, 조명연출에 적합한 조명 자재를 선정하여 적용함으로써 유지관리 비용이 절감됨을 알 수 있었다.

Recently one level higher intelligent switching board than established one by the application of intelligent building and digital system are being constructed. Therefore facility's high efficiency, high degree satisfaction, miniaturaization, standardization through application of communication technology and monitoring and controlling by computer system utilized by web-basis power control system and electric IT are practiced. Especially network must be constructed through unified IBS server that monitors every educational institute's switching boards in real time control system. And I intend to create methods to save energy and raise electricity quality by power demand prediction and remote-controled management and operation. In this thesis I intend to suggest measures of forming unified system through researching educational institute's ways of constructing switching board and status analysis and overcoming technical difficulties in user's side and saving and maintenance expense.

Major utilities have been focusing on R&D and nationwide business of AMI system which plays a vital role in SmartGrid whose concept is to maximize energy efficiency and optimize electric power facility management with exchanging real time information between utilities and consumers based on ICT technologies in power grid. In this paper, we suggest a power loss monitoring method using KEPCO's AMI system which is operating in fields and with the acquisition of AMI data and analyses verify the validation of a power loss monitoring method.

The portion of lighting power consumption for our country is up to 20~30% of the total amount. Currently, most of the DSM(Demand side management) of lighting power is delivered in supply of high efficient lighting to customers. On the contrary, applications of lighting power to power load leveling are still rare. In this paper, the simulations for various control types of lighting power for load leveling are tried, and we obtained the cost effective and optimal control method through that. This simulation was executed in test office with fluorescent light by us based on applying 8 control types(on, off & dimming), considering customers' satisfaction, for instance, minimum intensity of illumination allowed. According to the result of this test, we found that mixed type(chessboard(on-off) plus dimming control(10%)) is most effective.

In this paper, A web-based server system was developed based on PDA(Personal Digital Assistants) for controlling and managing light facilities on-line with wireless communication efficiently. The control box of current light facilities may be implemented based on simple operational function. The operational quality of the light facilities will be efficiently improved with some practical advantages such as reduction of required facility, manpower and time in managing the lights and control boxes by using the popular PDA.

A variety of Urban Rail Transit (URT) systems have been operating and they have different technology bases, causing a lot of difficulties in taking measures against trouble, training, upgrading, interoperability and so on. As such, a standardization project has been carried out to solve the problems by setting up the national standards for URT systems. A common database was built to provide the integrated engineering environment to the community of URT project. This paper discusses the design of the database and how it can be utilized in the successful promotion of the project. The products of the projects are stored into the database with traceability management to be referred to by other new URT projects for reusing and sharing the acquired knowledge through cross organizations.

Due to the frequent occurrence of dangerous wild animals in rural or mountainous areas. it has been increasing damage of crops in every year. Fight bell or electric fence is typically installed to chase those wild animals. But there are problems that it is impossible to drive out birds and spends high installation and maintenance cost. In addition, it is inefficient to the risk of electric shock effect. In this study, the proposed system can drive out hazardous wildlife and birds regardless of installation location through realtime detection with the multi-sensing based IoT platform technology. This study showed a very large significance effect that can reduce crop damage by wildlife and birds.

LED lighting because of high efficiency, long life, friendly environment, as a general lighting of the next generation, has been substituted for incandescent bulb and fluorescent lamp. The proposed system for use of solar battery is the intelligent controller for LED street lights which is improved the method of battery charging and charging efficiency in winter to extend battery life cycle, controlled lighting current according to SoC and in steps. Also, it is implemented emotional lighting which is controlled with the surrounding environment, by using colorful sub LED to take up 10[%] of a source of total light, white LED. As a lab results, the proposed system was implemented functions to adapt to the environmental changes, and improved the charging efficiency and battery life cycle.

Various DSM (Demand Side Management) programs have been developed and carried out to use the limited energy resources of human-beings reasonably. LED lighting is one of essential DSM programs and the development of technologies is ongoing vigorously. Recently, one-person households have been increased and the electricity consumption pattern is different with conventional households because residents live as a single. On the other hand, owners of the one-person households tend to not prefer to install high efficient appliances due to the cost increasement. Therefore, the existing DSM subsidy programs should be revaluated so that the owners decide to install high efficient appliances.
