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."

오늘날 소비자들은 생활수준의 향상과 더불어 제품 구매시, 그 제품이 가지는 가치 중에서 제품이 '사용자의 이미지를 얼마나 잘 대변해 주고 있는지' 하는 상징적인 이미지가 중요한 구매결정 요소가 되고 있다. 이러한 맥락에서 제품 디자인 개발에 있어서 사용자의 상징적 이미지에 관한 정보가 절대적으로 중요하나, 그 구체적인 사용자의 정성적(Qualitative) 정보를 조사하고 분석하는 방법의 개발은 무척 미약한 편이다. 이러한 점에서 사용자의 자아개념 추출 틀(framework)의 개발을 통한 사용자 이미지 정보의 제공은 디자이너에게 유용한 사용자를 이해 할 수 있는 가이드라인(Guideline)정보로써의 궁극적으로 디자인 방향설정에 도움을 줄 수 있을 것이다. 이러한 목적을 위하여 본 연구에서는 사용자군의 자아개념 추출을 위한 21개 언어적 항목을 개발하여 제시했으며, 본 연구에서 사례조사를 통해 개발된 21개 언어적 사용자 자아개념 이미지 평가척도와 사회과학분석 툴(인구통계학적 data분석과 인자분석, 군집분석)의 보완적 활용방안을 모색해 보았다.

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.

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.

오늘날 금융 산업은 개방화와 자율화에 따른 외국금융브랜드의 진출 및 증가, 다양한 금융브랜드의 신설 등으로 급속도로 변화하고 있다. 이러한 변화의 추세 속에서 기업들은 점차 자사의 브랜드 차별화를 위해 다양한 마케팅 방법을 동원하고 있다. 그 중 최근의 금융 브랜드에서 사용하는 '컬러마케팅'은 중요한 브랜드 차별화 요소로 인식되고 있다. 그러나 일부 브랜드를 제외하고 기업의 경영성향을 내포한 브랜드의 컬러마케팅과 투자자의 투자성향에 근거한 컬러선호가 상이함이 있다고 보여진다. 이는 커뮤니케이션의 목적인 브랜드이미지 문제와도 관계가 있을 것이라고 생각된다. 따라서 본 연구는 기업과 고객 간의 효율적인 커뮤니케이션 방안을 제시하기 위해 현재 증권회사들의 브랜드 컬러마케팅과 개인금융 투자자의 투자성향 선호컬러의 상관관계에 대해서 확인해 보고자 하였다. 롤랑 바르트의 컬러의 기호학적 의미해석과 실제 투자자들의 투자성향별 집단의 선호컬러와는 차이가 있음이 확인해 볼 수 있었다. 즉, 공격적인 투자성향을 가진 투자자의 경우 열정적이며 적극성을 상징하는 적색이나 주황의 강렬한 컬러를 선호할 것으로 예상 하였으나 분석 결과 뜻밖에도 의외의 컬러를 선호하는 것으로 알 수 있었다. 이러한 분석들을 토대로 증권사의 경영성향과 투자자의 컬러성향과의 관계를 보다 면밀히 조사하고 체계화하는 과정의 일환으로 본 연구 결과는 향후 맞이하게 될 자본시장통합법에 따른 시장개방에서 금융브랜드와 고객과의 커뮤니케이션 수단의 기초적인 연구 자료가 될 수 있기를 기대한다.
