본 연구는 공간특성이 서로 다른 두 공간, 주거/사무공간의 조명환경에 대한 평가구조를 비교 검토하고 각 공간의 행위에 적합한 조명환경을 제시하고자 슬라이드 사진을 이용한 평가실험을 실시하였다. 평가대상 슬라이드수는 주거공간이 28장, 사무공간이 26장이다 실험은 각 공간별로 분위기항목과 행위항목에 대해 각각 실시하였다. 평가항목은 분위기항목이 21가지, 행위항목이 14가지이다. 각 공간의 평정치를 이용하여 인자분석을 실시한 결과, 주거공간과 사무공간 모두 <활동성>,<안정감),<고급감)의 3인자축이 추출되었다. 그러나, 주거공간의 경우는 <활동성>인자축이 평가축을 이루었으며, 사무공간의 경우는 <고급감>인자축이 평가축을 이루었다. 행위항목의 인자분석 결과는 주거공간의 경우, <작업행위>,<휴식행위>,<단란행위>의 3인자축이, 사무공간의 경우 <작업행위),<휴식행위>의 2인자축이 추출되어 주거공간의 경우, 활동성 평가가 높은 조명환경은 작업행위에 적합하며 반대로 활동성평가가 낮은 조명환경일수록 휴식행위에 적합한 것으로 나타났다 사무공간의 경우도 마찬가지로 작업행위에 가장 큰 영향을 미치는 분위기 인자는 활동성으로 나타나 활동성평가 높을수록 작업행위에 적합하며, 후식행위는 평가성 평가가 높은 조명환경에 적합한 것으로 나타났다.

20C까지 단순히 밝혀주고, 점멸만 하는 조명형태가 21C부터는 밝기의 조정, 칼라의 조정이 병행된 감성조명의 시대로 도래하여, 주거생활 조명, 상업용 조명, 문화공간의 조명 둥에 본격적으로 도입되기 시작했다. 특히, LED 응용조명은 자동차 분야 및 PV분야 등 다양하게 활용되고 있으며, 연 4조원의 세계시장과 2,000억원의 국내시장으로 점유되고 있으며, 연평균 45% 성장 ($1995{\sim}2004$)으로, 성능은 향상되고, 가격은 년 $10{\sim}15%$로 인하되어 "미디어파사드"로 그 응용이 눈부시게 가속화 되는 실정이다. 조명기술의 눈부신 발전과 조명산업의 발전이 어우러진 가운데 조명 산업 현장에는 조명전문가의 소요가 급속히 발생되고 있는 반면에 실무형 조명전문가를 양성하는 교육기관과 프로그램이 턱없이 부족하여, 수요에 비하여 조명전문가 양성은 요원한 실정이다. 조명교육시스템을 구축하고, 실무형 조명전문가를 양성하고 있는 경북전문대학의 조명전문가 양성교육시스템을 참고로 하여, 보다 효율적인 단계별 중견조명 전문가의 양성에 대해 연구하여, 방향을 제시하고자 한다.

This study aims to investigate the effect of multisensory stimulation on relieving the stress experienced by drivers. The photoplethysmograms (PPGs) of 30 healthy subjects were measured, and their subjective response to stressful situations and normal driving were evaluated. The subjects underwent nonstimulation and multisensory stimulation in stressful driving situations. Heart rate estimation from the PPG was collected via an ear-type sensor to reduce movement noise. The signals acquired were sampled at 200 Hz using BIOPAC PPG100C. Heart rate variability (HRV) was analyzed to compare the effect of multisensory stimulation on stress situations. In the multisensory stimulation, blue, green, and yellow were used for the visual sensory system; white, pink, and brown noises were used for the auditory sensory system; and lavender, lemon, and rosemary were used for the olfactory sensory system. No difference was observed in the subjective evaluation; however, the HRV results showed an increased HF (%) and decreased LF (%) and LF/HF (%) in the multisensory stimulation (e.g., green, pink noise, and rosemary) when compared to the nonstimulation.

This study is the visually emotional identification lighting for easy to distinguish using 3colors LED on AtoN facility in shore and harbor, which have realized a controller for certainly express the mouth of a harbor by red light and green light of both sides a harbor and for synchronization at a time of right and left or serial sequential the harbor guidance light through synchronizer or timer by GPS. There is expectation effect that is prevent a confusion about distinguish of facility by ship's operator and to beautify a night scene of harbor, which is expressed to emotional identification lighting differ from great many lighting of harbor with variable color lighting the lighthouse body and vertical layer color lighting using LED. The function of AtoN is adapted that guidance light through synchronization or serial sequential lighting and display of harbor safety message by CW lighting, and this system is the power consumption greatly reduce by candle alternated high light LED.

This study on the methode is easied to distinguish with emotional visual lighting on AtoN facility using 3colors LED, and which is controlled to on-off switching of approach light in shore or harbor. The identification have easied to provide a differentiation between the AtoN facility of red and white light and surrounding light in harbor both sides. And the integrated controller have designed to left-right and serial sequential lighting system for harbor guidance using the GPS synchronous or timer. There is expectation effect that is prevent a confusion about distinguish of facility by ship's operator and to beautify a night scene of harbor, which is expressed to emotional identification lighting and variable color lighting on AtoN body by vertical layer color lighting using LED. In addition, the performance of AtoN is implemented to display with guidance light the harbor safety message by morse code lighting. Effectiveness of system is enhanced that age and power consumption reduce by candle alternated high light LED.

As LED becomes more important in lighting system, LED-based communication draws much attention. Only a single color has been used for this purpose thus far. However, as emotional lighting becomes more important, the need for color visible light communication is growing. In this paper, a transmission scheme for RGB color based communication is proposed that can transmit data while changing color constantly.

Today, the city greatly increase the interest in the night, increasing the importance of building and landscape lighting is a trend. Landscape lighting and a combination of factors, especially the media has been expanding in the domestic media facade. The facade of the building for the implementation of the screen to install the LED, or are projecting the image through the projector. The facade of this study present a paradigm shift in traditional media based on interactive and works by combining the artistry of the item type, art, colors, patterns, and interactions were drawn into 5 main topics. This section of the 83 kinds of domestic. Other media facade sample was classified. Categorized by 5 types of lighting techniques, lighting system, manner of expression, changing the way lighting design elements were based. Thus, the current trend changes, depending on the technical value and artistic value of the applied media facade lighting design should be applied to identify the elements and the combination of media facades and IT skills beyond simply directing programmed to communicate interactively with various designs Must be for you.

This thesis presents an emotion-based contents player platform that can change its visual and aural components as user's emotions. It analyzes the emotion as pleasant, unpleasant, aroused, and relaxed based on the physiological signals and the user's active response. Accordingly. the system reorganizes graphical and aural stimuli, such as, light, color, sound, in real-time. It can be used to develop and show the emotional contents and also be applied for the systematic analysis to find out how the components would affect the emotion. This paper describes overall the system architecture and the implementations of the sub-systems, as well as the actual contents built on top of the platform.
