Chroma key technique which composes images by separating an object from its background in specific color has restrictions on color and space. Especially, unlike general chroma key technique, image composition for stereo 3D display requires natural image composition method in 3D space. The thesis attempted to compose images in 3D space using depth keying method which uses depth information of Microsoft Kinect. Object was converted into point cloud type in 3D space after separating it from its background according to depth information. The image in which 3D virtual background and object are composed obtained and played stereo 3D images using a virtual camera. The research showed naturally composed stereo 3D images as well as the feasibility of applying stereoscopic 3D mixed reality image technology.

This study is to comprehend the interior space of the Royal Palace in the 15th Century, the early years of Joseon Dynasty. The subject of this study is limited to the center of the Royal Palace, that is Jeongjeon(正殿, the royal audience chamber) and Haengrang(行廊, which encloses Jeongjeon on four sides and has many rooms). It is very important to understand the usage of the interior space because the architectural space consists of the space unified by the organic function of the interior and the exterior space. But there are few studies on the interior space of Jeongjeon and Haengrang at the Royal Palace. Therefore, the purpose of this study is to understand the interior space of those buildings. The result of this study is following. Haengrang has several uses such as a night duty room, a storehouse, a government office or a banquet hall etc. So the interior spaces were finished with various methods that were suitable for the use of each room, and the material of the floor were the ground, Maru(the wooden floor) or Ondol(the Korean traditional heating system) There were held many kinds of ceremonies in Jeongjeon, and the government officials could not enter the inside of that building and took part in the ceremony on the front court of Jeongjeon, except the men performing the ceremony. But the high ranking officials could enter the inside when King gave a banquet and there, they prostrated themselves before King. They sat down with their legs crossed on the ground floor instead of sitting on a chair. When King held tea ceremony with Chinese envoys in Jeongjeon, they sat on Gyoui(交倚, a kind of armchair). Then, the government officials performing the ceremony in Jeongjeon prostrated himself around the King and the Chinese envoys and others stood around them.

본 논문에서는 태양광 발전시스템을 이용한 PWM(Pulse Width Modulation) 전압형 인버터를 전력변환기로 구성하 였고, 안정된 변조를 위해서 동기신호와 제어신호를 56F8323 마이크로프로세서에 의해서 처리하였다. PWM 전압형 인버터는 태양전지가 연속 발전할 수 없는 단점을 보완하기 위해 일반 상용전원과 연계함으로써 약 10～20[%]의 전 력 절감 효과를 얻을 수 있는 에너지 절약 전원 복합형 전력변환장치로 구성하였다. 그리고 PWM 전압형 인버터와 위 상동기를 위해서 계통전압을 검출하고 계통전압과 인버터 출력을 동상 운전하므로 잉여전력을 계통과 연계할 수 있게 하였다. 또한, 고조파를 절감한 출력을 유지함으로써 부하와 계통에 전력이 안정하게 공급될 수 있도록 제어 시스템을 적용하여 좋은 결과를 얻을 수 있었다.
