  • As part of the Fire Evacuation Service scenario using mobile applications, this study aims to find the appropriate colors to be used in the interface of the application and to define and apply colors that can positively and reliably affect human unstable psychology in the course of evacuating the room in case of fire. In the situation of fire, proper design and placement of the colored escape guidance interface is important, taking into account the psychology of the occupants. However, literature and previous research have shown that colors used to induce evacuation are not suitable for effective evacuation in case of fire. In this study, the purpose of the study was to provide a color that would provide psychological stability in the event of a evacuation in consideration of the psychological issues of those who are still in need of shelter, and to use it to help induce an efficient evacuation in the event of a disaster. Using the image evaluation method, the form and color of images have been derived through frequency analysis to a number of unspecified people, and the main and secondary colors of images were analyzed through KSCA color analysis. Finally, the final application color was constructed through mutual verification between the results by comparing and analyzing the colors obtained through the image evaluation analysis results and the KSCA color analysis results. The results of the study showed that the green line can help stabilize the human mind through comparative analysis with prior research. Therefore, the main color for guiding calm and calm applications in case of fire escape is proposed in the green line. In this study, the experiment with image evaluation cannot accurately measure the effect of factors on color among complex factors. A subsequent study of this will help quantify images if it allows the subject matter of color and image to be defined to some extent through factor analysis.

  • Various earth observation satellites need to provide accurate and high-quality data after launch. To maintain and enhance the quality of satellite data, it is crucial to employ a cross-calibration process that accounts for differences in sensor characteristics, such as the spectral band adjustment factor (SBAF). In this study, we utilized Landsat-8 and Sentinel-2A satellite imagery collected from desert sites in Libya4, Algeria3, and Mauritania2 among pseudo-invariant calibration sites to calculate and apply SBAF, thereby compensating the uncertainties arising from variations in bandwidths. We quantitatively compared the reflectance differences based on the similarity of bandwidths, including Blue, Green, Red, and both the near-infrared (NIR) narrow, and NIR bands of Sentinel-2A. Following the application of SBAF, significant results with reflectance differences of approximately 1% or less were observed for all bands except NIR. In the case of the Sentinel-2A NIR band, it exhibited a significantly larger bandwidth difference compared to the NIR narrow band. However, after applying SBAF, the reflectance difference fell within the acceptable error range (5%) of 1-2%. It indicates that SBAF can be applied even when there is a substantial difference in the bandwidths of the two sensors, particularly in situations where satellite utilization is limited. Therefore, it was determined that SBAF could be applied even when the bandwidth difference between the two sensors is large in a situation where satellite utilization is limited. It is expected to be helpful in research utilizing the quality and continuity of satellite data.

  • Shaman's play is significant in that it provided public theater for a long time in the theatrical and dramatic history. Unlike upper class who could call entertainer or Korean geisha in the traditional society, the majority of ordinary people could see professional performances through gut. Therefore, the shaman of the traditional society pulled the play which developed in the gut and the outside play into the gut and prepared the performance street for the ordinary people. shaman's play, apart from the religious context, has also functioned as a theatrical performance. Through shaman's play, you can see the process of ritual development into play. Shaman's play is a ritual ritual of expel calamity in an agriculture based society. In Korean consciousness, evil spirits are thought to bring disease or disaster to humans, so they should be good for evil spirits. This is a ritual that goes hand in hand with the Confucian Yeoje and the Buddhist Suryukjae. Most traditional plays, including masque performance, tend to weaken and become stifling after the designation of intangible cultural properties. However, shaman's play is transformed every time it is executed and is given a new meaning. Depending on the ability of the shaman to respond to and accommodate social change, adaptability is excellent depending on the situation in the field. Shaman's play has richness, prevent calamity and playful elements such as imitation of god and sexual connection based on the element of shamanism. In addition, it is necessary to pay attention to the meaning and the direction of Shaman's play because it is differentiated into play including social subject beyond mere magic imitation.
