This paper is a thesis on media art technology for high-tech performances and exhibitions. After creating an interactive stroke in VR, it is projected in real time through a media facade technique. Among our traditional dramas emphasizing linear movements, movements were extracted from the Bongsan mask dance, and the movements of the lines were used in a media art performance called 'Multi-face Convergence'. When motion data enters the virtual space, geometry consisting of faces is created in the VR space. The created strokes can be set with various brush types, and when performing, a stroke with a red fire effect that matches a dynamic movement was used. It was made to be able to harmonize with the dancers performing the Bongsan mask dance. The medium called VR has characteristics that are not suitable for melting into a performance, but in this performance, it has overcome its limitations by using a technique called media façade. We propose the world's first performance technique that combines interactive strokes with traditional dance performances.

As the contemporary times entered, the attention focused on the 'human's perception on a space' as much as on that a space's physical structure, so the meaning of a space became defined depending on how a person thought over and behaved in the space. As this age is the times of consilience and integration, a space accepts new technologies beyond being defined simply based on the space's structure and its shape and tries to provide different, 'strange experiences' from tho se felt by the human until now. Recently in the filed of space design, it can be seen that the spae design's connection with various technologies affects on considerable influence on the all fields of culture and arts like space marketings, media arts, exhibitions and performances as well as the buildings. Especially. the fusion of digital images and architecture is actively developed. Images possessing the moving light's attributes shine a city night and day and a building changes a city's appearance itself by adding new materials on the surface of building. It is the purpose of this study to study what new experiences the human gets and creates from his interaction with spaces based on such technological fusion. By studying some cases that used the digital media as a mediating instrument as the way presenting spatial experiences to the human, this study intended to identify what design factors were applied and to find appropriate directions for space desig in relation to what new trials can be done.

The methods used in this study included investigation of media facades used for landmarks in downtown areas in previous studies, visits to these areas, and recording of media facades. The changes in the colors or the size of buildings were analyzed among the recorded cases and 12 of these cases were selected for further study. The sensibility preference of the media facades was evaluated by sorting the 12 kinds of media facades, and providing them as materials to a group of 60 participants (40 undergraduate and 20 graduate students majoring in architecture and design) consisting of an equal proportion of males and females. This study addressed the following four_stage questions: 1) Five questions of recognition evaluation about media facades and the cognitive evaluation items of emotional vocabulary and color preference in each research case; 2) sensibility preference items regarding the media facade color design; and 3) design evaluation items of the media facades; 4) Video clips and still images were recorded from a middle distance at 7p.m to 11p.m. in central New York, Singapore, Seoul, and Beijing. The participants looked at the changes in colors through the video clips in each case and evaluated their preferences through 23 pairs of emotional vocabulary items using system dynamics. Construction of an emotional vocabulary followed, based on previous studies about media facades and color design. To evaluate the sensibility preference and the perceived representative colors of the media facade, this study suggests new emotional responses that depended on the color emotional vocabulary of light in the LED lighting technical evaluation methodology. A media facade with a moving change of colors, unlike a fixed landscape color design, suggests a new communication method based on architectural factors. New architectural color coordination can be presented for urban landscapes at night. Designs that factor in the pedestrians' emotional vocabulary or preference should take precedence over the use of high luminance and various colors.

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 was conducted to examine the effect of the light source for the media facade of the 10-story Gyeongcheonsa Stone Pagoda on the pagoda's restoration materials. To restore the pagoda, two types of epoxy resin-L-30, Araldite (AW106, and HV953U)-were used, and the photostability of the restoration materials and the acceptable lighting irradiation time were estimated through accelerated aging experiments of the restoration specimens. Six types of specimens were used in this process: a specimen painted with blue and yellow pigments for each resin type, and an unpainted specimen. Among them, the ΔE of the unpainted specimens (BA) of Araldite AW106 and HV953U was the highest of 4.66, and the acceptable light irradiation time was about 130,000 hours if the change rate of ΔE is limited to about 1. It was confirmed that the BA specimens were losing their characteristics due to light, as their reflectance and transmittance increased and the absorbance decreased, making them more transparent than their original color. It was found that the painted specimens had a low change rate of ΔE, with insignificant changes in their reflectance, transmittance and absorbance. Therefore, the use of pigments with high photostability provides more restoration materials options.

In the contemporary age, social environment has changed from analog to digital. As a media is developed, the public is more familiar to digital than analog. In this society, media art rises as new art. One of the most useful methods in the media art is projection mapping. In this paper, I propose a realization process of artwork 'Cloned Me' that is realized by projection mapping method. Artwork is formed by projecting image contents that are visualized a music on a steel structure. It is different from media facade that the object projected contents has a story composition. It is a strength that the object and contents are connected by story and composition. Also it can be modified each other easily for harmony because the structure is assembly-type. A face that is projected by beam projection is consist of unique structure not fixed rectangular frame. Artwork 'Cloned Me' has significance that it reflects the present age to develop digital cloning.

The 2020 Gwangju Media Art Festival (2020 GMAF) was held in the area of the National Asian Cultural Center. Under the slogan "The entire Gwangju shines under the theme of "Aesthetics of Light and Coexistence," the media festival demonstrated projection mapping to Jeonnam (former) Provincial Office at the DATA+ Research Institute of Chung-Ang University's Graduate School of Advanced Video. This paper focuses on explaining the overall production process and content development of projection mapping demonstrated in the Jeollanam-do Provincial Government, which is a symbol of Korean democratization and is located in the center of Gwangju, Jeolla-do. It was intended to faithfully express the history of the 2020 GMAF and Jeonnam (former) provincial government, Gwangju's history, and democratization records. It was intended to show images, background sounds, sound effects, and visual effects using various special effects and high-power laser devices using unique characteristics of projection mapping. To this end, about 5 minutes and 30 seconds of content were planned, and it was divided into parts and topics, and one individual story was developed for each chapter.
