Stamps are the smallest image symbols that can be read in the period, and they include the history, culture, politics, and figures and events of the issuing country. In particular, the stamps of the past presidents include the contemporary history of Korea, and reexamining and reviewing the meaning of the presidential stamps historically has a meaning that can not be overlooked as a researcher who studies the image of political leaders. In this study, the scope of research from the first republic to the fifth republic, where the publicity of political leaders through the advertisement of stamps and placards was high, was conducted and the leader image formation and change process centering on the former presidents Rhee Seungman, Park Jeong Hee, Chun Doo Hwan, Respectively. For the interpretation of the image of political leaders according to the changes of time, the images were classified by using Osgood's Semantic Differential Scale, and the images were analyzed using Saussure's semiotics. The image continues to move and change, and the conclusion that the image of the political leader of the time is not a simple personal image but a social product reflecting the specific age of the era.

The regression analysis and Adaptive -Network based Fuzzy-inference system (ANFIS) were applied to the explanation on human's visual texture of cotton fabrics with 7 mechanical properties. The ANFIS uses the structure with fuzzy membership function and neural network. The results obtained by the statistical analysis through the coefficient of correlation and regression analysis showed that subjective texture had a linear relationship with mechanical properties. But It had a relatively low coefficient of determination and was difficult that the statistical analysis explained other relationship with the exception of a lineality and interaction among mechanical properties. Comparing the statistical analysis, the ANFIS was an effective tool to explain human's non-linear perceptions and their interactions. But to apply ANFIS to human's perceptions more effectively, it is necessary to discriminate effective input variables through controlling the properties of samples.

Odor sensing system that is electronic nose device and its signal processing technique has potential to become a critical service for the people who require tangibility of sense of smell in the multimedia communication. PCA(Principal Component Analysis) have been used for dimensionality reduction and visualization of multivariate measurement data. PCA is good for estimating importance value by variance of data but, have some limitation for getting meaningful representation from odor sensing system. This paper explain about how to analyze the data of odor sensing system by ICA(Independent Component Analysis). We show that ICA can give better result like sensor drift analysis, dimensionality reduction and data representation by improved discrimination.

The function of music in a motion picture ranges widely from supporting the storyline to being the main storyline delivering the major plots. This trend and can be seen in recently produced films, advertising as well as in music videos. Many attempts were made to express music visually in the past. But it was through Disney's creative production, "Fantasia", that such attempts became a reality in a motion picture. This paper will look into the difference between the "Fantasia" and "Fantasia 2000" through a comparative analysis of the correlation between the musical element and the storyline of the 2 Disney animation movies. The most distinct difference is that the "Fantasia" has a storyline that is faithful to the original interpretation of the true meaning of the music, while, on the other hand, the "Fantasia 2000" has a storyline that endeavors to express the special features of the overall sound of individual pieces as best as possible. And the differences between the two animations, thus compiled, is hoped to facilitate and enhance a better understanding of the two Disney's finest animations.

The purpose of this study is to comprehensively analyze elementary school teachers' perceptions of the use of artificial intelligence in education. Recently, interest in the use of artificial intelligence has increased in the field of education. However, there is a lack of research on the perceptions of elementary school teachers using AI in education. Using descriptive statistics, multiple linear regression analysis, and semantic differential meaning scale, 69 elementary school teachers' perceptions of using AI in education were analyzed. As a results, artificial intelligence technology was perceived as most suitable method for assisting activities in class and for problem-based learning. Factors which influence the use of AI in education were learning contents, learning materials, and AI tools. AI in education had the features of personalized learning, promoting students' participation, and provoking students' interest. Further, instructional strategies or models that enable optimized educational operation should be developed.

Grit, defined as "perseverance and passion for long-term goals", is a known personality trait that successfully predicts high performance in various fields. In spite of extant evidence of the effectiveness of grit, research has not yet clarified the relationship between grit and conscientiousness, a highly correlated personality trait. In this study(N = 355), we examined the effect of grit and conscientiousness on academic achievement, mediated by self-determination motivation. As a result, grit and conscientiousness both predicted academic performance, and intrinsic motivation mediated these relationships. However, conscientiousness no longer related with motivation and academic achievement when grit was controlled for, whereas grit maintained its relationship with motivation and achievement even when conscientiousness was controlled. This result indicates that although the two psychological concepts overlap to some extent, grit has a unique motivational and behavioral effect that distinguishes it from conscientiousness. The present study expands the current understanding of grit with its comparison between grit and conscientiousness. We suggest future research ought refine the grit scale to establish its discriminant validity.

The purpose of the study was to validate the Korean version of the Heterophobia Scale for Gay Male (HGM). Heterophobia refers to the rejection, fear, and avoidance that sexual minorities feel against of heterosexuals. The three subscales of HGM assesses the unease/avoidance, disconnectedness, and expected rejection fromwith heterosexual male. To validate the Korean HGM, item translation, item analysis, and exploratory factor analysis were conducted. From the Using exploratory factor analysis of the Korean version of the HGM(N=213), per 13 items, a 3-factor model consisting of 13 items wereas determined. The Cconfirmatory factor analysis supported the goodness of fit of the 3-factor structure of the K-HGM (N=153) and showed adequate model fit, K-HGM showed adequate the internal consistency, convergent validity, discriminant validity and Criterion validity was good with other related scales (K-SOMS, K-MISS-G, SDS-9, and RS). In conclusion, the K-HGM is a valid measure of heterophobia for gay male within the Korean population. Based on the findings, implications, practical use, limitations, and suggestions for future study are discussed.

The present study aimed to investigate the discrimination between employee voice and silence behavior in measurement: it is silence behavior the absence of voice or not? It was examined using confirmatory factor analysis. Five measurement models based on the suggestion of Pinder & Harlos(2001) and Van Dyne, Ang, & Botero(2003) were compared. Additionally, the hierarchical multiple regression analysis was conducted for examining the incremental validity of silence behaviors over voice. A total of 204 employees who worked with their own supervisor were surveyed. Results indicated that silence behavior could be a separate construct from voice. Findings also showed that silence behaviors could be distinguished by the level of concreteness in definition, difference in content of motivation and have the incremental validity over voice in only acquiescent Silence. From these results, the theoretical implications of findings, limitations, suggestions for future research were discussed in discussion.

Typography in visual communication design is 'potential form' hidden within a space. Showing rhythm in typography is making 'aesthetic sense' in a graphic which has formative characteristics, the way of expression is very important. When the rhythm is recognized through visual stream, Rhythmic Sense is formed. The research will present a new form of the Visual Rhythmic Sense by analyzing typography works out positively. First of all, I researched works done by Fillippo Marinetti, Robert Massin, Wolfgang Weingart, and David Carson for their vigorous experimentalism in typography in forming visual rhythm. I used S.D. Scale method to analyze characteristics of visual image and VARIMAX for factor analysis reaching types of visual rhythm, which could be classified as following. (1) Synesthesia Rhythmic Sense (R-synesthesia) means that the senses are conveyed through 'visualization of auditory sense' and 'visualization of touch' (2) Simultaneous Rhythmic Sense (R-simultaneity) means that the time and space co-exist in one plane. (3) Connective Rhythmic Sense(R-connection) means that different factors (Within one plane) co-exist interacting with one another and creating a unified impression through such a process. (4) Artist Oriented Rhythmic Sense ($-artist) means that the artist interprets the content subjectively and expresses his/her impression, thereby, attracting a gaze of audience systematically and arbitrarily. (5) Reader Oriented Rhythmic Sense(R-reader) avoids the existing legibility formed through aggressive engagement of the reader.

Discussion of facial image of the movie starts is recognized as an art movie that started from silent film period. Critical discussions on the facial image initiated with the emergence of 'close-up' are performed in the context to claim the superiority of close-up format. Therefore, the trend of critical discussion on the facial image differs from two perspectives to perceive close-up in this era. The first perspective is to privilege both face and close-up since close-up is recognized as the unique tool to realize the face considering close-up as the independent body to have new aesthetic feasibility of the movie. The second perspective is to consider close-up as one of the plots in the movie language to complete its narration. In this case, it is perceived as just a short, which has no differentiation from the others, as long as the facial image does not interfere the completeness of the narration, because the characteristics of close-up to highlight the subject more than the other short is not recognized as the unique form to complete the movie, and because it has the meaning only when the subject and the format aim to maintain the completeness of the narration.
