Modern Hanbok tends to use new colors based on traditional colors and their symbolic meanings. In addition to the traditional colors, various expressions have been increased, it is necessary to consider the color and color trend used in modern clothing. This study focused on the period 2011 - 2020 and analyzed the main color and coloring method of top and skirt by year with 450 data from a total of 81 wedding magazines. The results of examining the characteristics of traditional colors during the target period are as follows. First, the main color of the Jeogori showed a distribution of various colors in the first half, but the main color of the skirt concentrated on black, white and light pink in the second half. Second, while the use of blue and green systems decreased, Dang-ui color changed to warm yellow, green, and red systems. The Baeja used plain dark white in the first half; however in the latter half, they changed to white or accented colors. The one-piece used various colors in the first half, but only black and white appeared in the second half. Third, in the upper and lower colors of Hanbok, the blue-red color, the traditional contrast color of the first half, decreased significantly in the second half. The appearance rate of proximity for the complementary color harmony of white-red color and the adjacent color harmony of white-blue increased.

Recently, influence of color has been expanded in various fields including design field. Among human five senses, visual sense is best for information capturing, and 80% of information judgment by visual sense is from color. Color is emotion and image. Hanbok is marked by its beautiful color combinations. The guiding principle of such color chords was Obangsaek, or the traditional Korean five base colors. The method of this study is to consider concepts of Obangsaek derived from the principles of yin-yang and the five elements and is to investigate application of Obangsaek. And the purpose of this study is to understand traditional colors and is to provide judgment criteria on various color combinations based on Korean aesthetic sense for development of textile design. The degree of nation culture depends on the level of research, analysis and application on traditional colors. Obangsaek, Korean traditional color is splendid and primary color. Also, Obangsaek has symbolic and lucky meanings. These colors are still the primary source of coloring. Obangsaek has been reinterpreted by application on textile design, some into base colors and others into diverse shades. So this study will help in the aspect of development on Korean style design.

Clothing is a powerful medium that reflects the environment, situation, and trends of the times. It has been an important subject of semiotic analysis, particularly in East Asia. While Korea, China, Japan, and Mongolia are geographically close, they have each developed unique characteristics in their clothing. These characteristics continue to evolve over time. The purpose of this paper is to explore the modern fashion design characteristics of these four East Asian countries by using the Greimas symbol square. To achieve this, the paper follows a research method consisting of several steps. First, it considers previous studies on the topic. Second, it analyzes fashion collections from Paris, Milan, New York, and London, as well as the Seoul and Cruise collections, from 2013 to 2024. Third, it compares costumes and modern fashion designs of brands known for their East Asian influences. Finally, it applies the framework of the Greimas symbol square to analyze the main elements of dress culture in these four countries and their significance in modern fashion collections. The findings of this study reveal that East Asian costume culture can be summarized into four distinct characteristics in modern fashion. Korea is characterized by "moderation," China by "exaggeration," Japan by "distinctiveness," and Mongolia by "symbolism."

In collaborative recommendation two models are generally used: the user model and the article model. A user model learns correlation between users preferences and recommends an article based on other users preferences for the article. Similarly, an article model learns correlation between preferences for articles and recommends an article based on the target user's preference for other articles. In this paper, we investigates various combination methods of the user model and the article model for better recommendation performance. They include simple sequential and parallel methods, perceptron, multi-layer perceptron, fuzzy rules, and BKS. We adopt the multi-layer perceptron for training each of the user and article models. The multi-layer perceptron has several advantages over other methods such as the nearest neighbor method and the association rule method. It can learn weights between correlated items and it can handle easily both of symbolic and numeric data. The combined models outperform any of the basic models and our experiments show that the multi-layer perceptron is the most efficient combination method among them.

According to the improvement in quality of life and the progress of user's taste in this modern society, people great deal with the symbolic meaning of product which express user's self-concept(image). Therefore, this kind of information of users' image is needed to deal importantly for the product design development processes, particularly, the early stage of design development such as the concept design development stage. But, there is not much analysis tools which deal qualitative data of users for the design development. From this reason, the supply of information of user's image through the development of verbal analysis method of user's self-concept will help a designer. For this purpose, this study not only developed the twenty-one factors in order to evaluate user's self-concept, but also suggested that the new approach method that can classify user's group within the same characteristic of user's image using the twenty-one developed verbal measurement items with tools of statistical analysis for the design direction of product. The developed this verbal analysis tool was testified through the case study in this research work.

The purpose of this project is the derivation and development of techniques for the new estimation of robustness for the systems having uncertainties. The basic ideas to analyze the system which is the originally nonlinear is Lyapunov direct theorems. The nonlinear systems have various forms of terms inside the system equations and this investigation is confined in the form of bounded uncertainties. Bounded means the uncertainties are with same positive/negative range. The number of uncertainties will be the degree of freedoms in the calculation of the stability region. This is so called the robustness bounds. This proposition adopts the theoretical analysis of the Lyapunov direct methods, that is, the sign properties of the Lyapunov function derivative integrated along finite intervals of time, in place of the original method of the sign properties of the time derivative of the Lyapunov function itself. This is the new sufficient criteria to relax the stability condition and is used to generate techniques for the robust design of control systems with structured perturbations. Using this relaxing stability conditions, the selection of Lyapunov candidate function is of various forms. In this paper, the quadratic form is selected. this generated techniques has been demonstrated by recent research interest in the area of robust control design and confirms that estimation of robustness bounds will be improved upon those obtained by results of the original Lyapunov method. In this paper, the symbolic algebraic procedures are utilized and the calculating errors are reduced in the numerical procedures. The application of numerical procedures can prove the improvements in estimations of robustness for one-and more structured perturbations. The applicable systems is assumed to be linear with time-varying with nonlinear bounded perturbations. This new techniques will be extended to other nonlinear systems with various forms of uncertainties, especially in the nonlinear case of the unstructured perturbations and also with various control method.

Linear regressions and evolutionary nonlinear regression based compensation techniques for the short-range prediction of wind speed are investigated. Development of an efficient MOS(Model Output Statistics) is necessary to correct systematic errors of the model, but a linear regression based MOS is hard to manage an irregular nature of weather prediction. In order to solve the problem, a nonlinear and symbolic regression method using GP(Genetic Programming) is suggested for a development of MOS for wind speed prediction. The proposed method is compared to various linear regression methods for prediction of wind speed. Also, statistical analysis of distribution for UM elements for each method is executed. experiments are performed for KLAPS(Korea Local Analysis and Prediction System) re-analysis data from 2007 to 2013 year for Jeju Island and Busan area in South Korea.

The purpose of this study is to see and compare the contemporary Korean-Thai female poems from a feminine standpoint to newly clarify the textuality of their poems. The textuality defined in this manuscript is the text of Korean-Thai contemporary female poems. To newly clarify the textuality of their poems are to go against the existing discussion method and to newly read out the text as re-vision method. This discussion is to analyse deeply how the central exis composing a text which is the identity of woman in a body, appearance of uttrance, or action of abjection is exposed in gender space and to identify the poem's textuality. In other words, through in-depth analysis of the text of poems, which are very complicated as a skein of yarn, place a high value of Korean-Thai female poems. Transcending time, nations and races, if the text of female poem would not free from a biased male-dominated thinking or make a mystery of female poem textuality without critics or tend to be stereotype the text of poem as pathos of female, it would not get out from man-centered reading. To escape from the state of sexual discrimination, the new reading method was seriously analysed and found out that the female text poems not only implicate sexual discrimination but also link to expansive cultural and social structure. And for that reason, this study raise a question to male-dominant sexual discriminated norm. It is very significant that through this elaborate and in-depth text poem analysis, a creation process of female poem is traced. Eventually, the comparative study on Korean-Thai female poems is meaningful and worthy in regard to the contribution to promotion of cultural exchange between korea-Thai two nations and furthermore extend to East Asia to make a basement for the vitalization of Asia comparative literature.

Today, communication trend of financial brand has changed fast with more foreign financial brand's introduction, emerging financial brands through the openness. With the trend of changing, companies are introducing various marketing methods to differentiate its brand image. And color marketing becomes an important tool for the differentiation. However, except a few brands, brand color which expresses management character of a company is different from the customer's preferred color which is based on investors' investment tendency. This may be related to the brand Image which is final goal of communication. Therefore, this study suggests effective communication method between company and customers by analyzing preferred color of customers by their investment tendency and comparison analysis security firms' color marketing strategy. As a result, it was found that Roland Barthes symbolic meaning of colors is different from the symbolic meaning of the groups of investor tendency. For example, I assumed that aggressive investors preferred strong color like red or orange, but the survey result was far from my assumption. I hope this study can be a good foundation for logical and scientific marketing in communication between security companies and customers in more open market with introduction to the Capital Market Consolidation Act.
