With developments of architectural and information technologies at the knowledge-information oriented society in the 21st century, there are the needs on intelligent buildings equipped with advanced systems to integrate both technologies. The intelligent building means a smart building which provides comfortable environments, realizes fast and speed information and telecommunication network services, and maximizes work productivities by adopting various systems suitable to uses, sizes, and functions of buildings. In order to meet these needs of the times, the domestic intelligent building certification system has been enforced in 2006. Recently, the intelligent building certification system was newly revised for revitalizing the spread of intelligent buildings. Thus, this paper investigates rating criteria and assessment standards of the new certification system focused on office building projects and suggests strategies for obtaining certifications by analyzing cases which were certified on the previous version of the system.

This study aims to measure amount of the reduction ratio of energy consumptions by the daylight responsive dimming systems, which uses daylighting and electric lighting. The results of this study show that the reduction ratio of electric power is better 'clear sky' by sky condition and 'window side of room' by zoning. When calculating reduction ratio of energy consumptions with used times in real office space, it tells that the result of real office was higher ratio than that of experimental space. For this study which presents efficient use of daylight in office environment, it will be basis of improving energy performance.

Precise Point Positioning-Real Time Kinematic (PPP-RTK) is a high accuracy positioning method that combines RTK and PPP to overcome the limitations on service coverage of RTK and convergence time of PPP. PPP-RTK provides correction data in the form of State Space Representation (SSR), unlike RTK, which provides measurement-based Observation Space Representation (OSR). Due to this, PPP-RTK has an advantage that it can transmit less data than RTK. So, recently, several techniques for PPP-RTK have been proposed. However, in order to utilize PPP-RTK techniques, performance analysis of these in a real environment is essential. In this paper, we implement the local network PPP-RTK and analyze the positioning performance according to the distance within 100 km from the reference station in Korea. As results of experiment, the horizontal and vertical 95% errors of local network PPP-RTK were 6.25 cm and 5.86 cm or less, respectively.

위키는 사용자 누구나 문서를 생성하고 수정이 가능하여 지식관리 도구로 활용이 되고 있다. 위키는 사람을 대상으로 하는 지식 공동 저작과 공유를 위한 기반 구조 중 하나로서 웹에서 운용되며, 내용은 웹 문서 서식을 위한 간단한 마크 업 언어와 자연어로 구성된다. 이 논문은 minimal Apache server 를 USB 에 저장하여 사용할 수 있는 Dokuwiki 에 지식 기능들을 추가한 MWO(Mobile Web Office)를 제안한다. 휴대 성과 이식 성이 있다는 장점을 기반으로 하여 지식 기능들을 설계하여 더욱 효율적인 시스템을 제안한다. MWO 는 공통의 업무나 관련된 그룹의 구성원들이 정보들을 공유하고 시간적, 공간적 제약을 제거하고 그룹구성원의 팀워크와 작업생산성을 향상시킴으로써 업무효율을 증대하고 조직경쟁력을 강화할 수 있다.
