In this paper, an experiment was done where the input device used the linear multiple regression and the sRGB color space to perform a color transformation. The output device used the GOG, GOGO and sRGB for the color transformation. After the input device underwent a color transformation, a $3\;{\times}\;20\;size$ matrix was used in a linear multiple regression and the scanner's color representation of scanner was better than a digital still camera's color representation. When using the sRGB color space, the original copy and the output copy had a color difference of 11. Therefore it was more efficient to use the linear multiple regression method than using the sRGB color space. After the input device underwent a color transformation, the additivity of the LCD monitor's R, G and B signal value improved and therefore the error in the linear formula transformation decreased. From this change, the LCD monitor with the GOG model applied to the color transformation became better than LCD monitors with other models applied to the color transformation. Also, the color difference varied more than 11 from the original target in CRT and LCD monitors when a sRGB color transformation was done in restricted conditions.

The stage is ceremonial and legendary space unlike the ordinary world. Performance is not simply scrip-staged, but spatial art based on tempo that transmits extreme condition. The stage art is a visual art combined with stage settings, lighting, customs and the like. I exemplify the stage of Middle Age and Renaissance in the history of the art of public performance and so I review that what meditative functions each stage perform and that as what pattern of media it can be conceptualized. In this thesis, I divide the places of public performance Into the spaces of proscenium and polygon and also set up the concepts of hot and cool that McLuhan presents for each space. So, the degree of participation could be different according to the distinction of quantity of information, which is communication following the patterns of spaces. The basis of public performance might be the communication between co-actors and audiences. Since the sense of the art of public performance is the art in the process of establishing the meaning based on the communication with co-actors, it is not a confirmed and fixed one, but rather a reflexive one that can be created and changed continuously. Therefore, audiences should be regarded as the subjects, who are making the art of public performance with co-actors.

In this study, we attempted to propose operational directions for each space in order to transform the newly built library in Yangpyeong-gun into a space for cultural enjoyment and creativity development for local residents. To this end, the purpose is to understand the space composition status of Yangpyeong-gun public libraries and establish an operation plan (draft) for the space to be constructed. To this end, we analyzed the names, operation status, and cases of similar spaces in other libraries, and analyzed the spatial characteristics of library cases to establish a space operation plan for the Yangpyeong-gun public library. As a result of the study, it is important to utilize spaces such as children's resource rooms to improve early reading habits for infants and children, contribute to development, and develop various senses, and small theaters should be planned with a focus on large-scale performances. Furniture and space for reading and relaxation should be provided next to Byeokmyeonga & Bookstair, and it should be operated as a communication space where small talk is possible within a certain limit. It is necessary to operate the multipurpose room by activating experiential creative activities and creative performances. It is necessary for the club room to establish an operation plan through regular communication and opinion sharing. The maker space space is a space that supports various creative activities, and the general data room is a place that provides materials on all topics and must be operated by regularly communicating with users and reflecting their opinions. Lastly, I would like to suggest that the family room should be used like a book cafe where children and parents can freely drink tea together in the same space.

In this paper, we describe a pointing accuracy establishment and efficiency measurement of 13.7 m antenna for observing cosmic radio wave which is in the first stage just after finishing its installation. The initial stage of pointing model, 1 and 2 were set up with the observational data of Sun and Moon which are large in visual diameter and also strong in radio intensity. Based on this model, model 3 and 4 were established within the available operational range, i.e., 3.8" in azimuth deviation, 10.5" in elevation deviation, with the observational data of SiO maser source which is a point source and distributed in overall sky. Both apeture efficiency anhd beam efficiency were measured by observing Venus whose brightness temperature is well-known. The resulting corrected efficiencies were 35% and 50% respectively.

Despite numerous efforts on reducing road-kill worldwide, the collisions have been occurring continuously. Many factors are affecting road-kill occurrences and the effect is various by species. We investigated Hydropotes inermis argyropus road-kill characteristics on the national highway. We examined 9,099 H. i. argyropus road-kill points with distance to the gaps on road (interchange and intersection) and distance to six natural land-cover types as explanatory variables. We also examined the number of road-kill occurrences according to temporal variation using chi-square test with 9,658 events. In general, H. i. argyropus road-kill location tended to occur close to the gaps on road, agricultural lands and forests. The average distance from road-kill to the gap was 694.7 m and 78.6% of the collisions were occurred within 1 km from the gaps. In addition, Kruskal-Wallis test showed the distance between road-kill points and each land cover and the gaps was significantly different. The temporal analyses showed that the differences of the H. i. argyropus road-kill frequency are significant in both month and season. Our results implies H. i. argyropus road-kill location tended to occur close to the gaps on road, agricultural lands and forests in general, especially during May and June, according to their seasonal behavior. Thus, we suggest there is a need of concentrated management on the roads with specific characteristics for both wildlife and human safety.

In this talk, we will review extragalactic science cases with NISS and SPHEREx. With its capability to perform a low resolution spectroscopy over a wide area, NISS and SPHEREx can provide valuable information about the evolution of spectral shapes of galaxies in different environments over cosmic history. This talk will focus on the cases for the studies that are closely related to the galaxy evolution and formation.

In this paper, we develop a vowel training assistant method using vowel formant statistics. Formant statistics were obtained from a PBW set consisting of 452 words from 8 persons. Then we calculated distance from input formants to each center of vowel formant space. Based on the distance, directions could be given to correct the speaker's manner of articulations, i.e. position of jaw and tongue.

In this study and design, I explore the visual communication design process related to wayfinding in Wonkwang University Hospital in Iksan City. The purpose for designing an integrated is to graphically communicate the complex information. I have designed a graphic information system combining graphic elements such as typography, color, image and text layout, and graphic image to present interpretive and communicative processes. As a result of designing, the wayfinding is s term used to describe the program of applying environmental graphics and or architectural sign systems. In other words, wayfinding is the art of helping people find their way by utilizing visual communications such as signs, directories, landmarks, edges, paths and so on. Wayfinding can also be explained as the ability to know where one is in space and how to find one's way through space. Wayfinding design then becomes a systematic arrangement of the variables that allows patients and visitors to successfully find their desired destinations, especially in a hospital.

Few samples face recognition has become a highly challenging task due to the limitation of available labeled samples. As two popular paradigms in face image representation, sparse component analysis is highly robust while parts-based paradigm is particularly flexible. In this paper, we propose a probabilistic generative model to incorporate the strengths of the two paradigms for face representation. This model finds a common spatial partition for given images and simultaneously learns a sparse component analysis model for each part of the partition. The two procedures are built into a probabilistic generative model. Then we derive the score function (i.e. feature mapping) from the generative score space. A similarity measure is defined over the derived score function for few samples face recognition. This model is driven by data and specifically good at representing face images. The derived generative score function and similarity measure encode information hidden in the data distribution. To validate the effectiveness of the proposed method, we perform few samples face recognition on two face datasets. The results show its advantages.

The radiating or receiving characteristics of array elements (i.e., antennas) are changed from those of isolated elements due to mutual coupling effects and the array performance becomes different from those originally designed by assuming isolated elements. The effects of mutual coupling on the performance of a rectangular array with triangular grid geometry of dipoles above a ground plane are discussed with respect to element pattern. The concept of element gain function is used to examine the effects of mutual coupling on the array performance in terms of sidelobe level in the uniformly spaced and space-tapered rectangular arrays with triangular grid geometry of dipoles. It was shown that the sidelobe performance improved in the space-tapered array compared to the uniformly spaced array in the presence of mutual coupling effects. Computer simulation results are presented.
