The purpose of this study was first, to clarify the clothing benefits that Uzbek female college students seek through clothing products; and second, to determine whether there is a difference in clothing involvement and clothing purchasing behavior according to the type of clothing benefits. Data were collected from 290 female university students from Tashkent, Uzbekistan, and analyzed using factor analysis, K-means group classification analysis, ANOVA, Duncan test, χ²-test, and frequency analysis. Respondents were classified into four types according to their clothing benefits: individuality/economy-pursuit, comfort-pursuit, fashion/brand-pursuit, and indifference. Significant differences were identified in terms of clothing involvement, information sources, clothing evaluation criteria, clothing store attributes, clothing wearing conditions (including monthly clothing expenses), number of purchases per year, clothing purchase location, clothing preference style, and clothing dissatisfaction. The fashion/brand-pursuit and personality/economy-pursuit types were influenced more by fashion and symbolism of clothing involvement, information sources, clothing evaluation criteria, and clothing store attributes. The individuality/economy-pursuit type purchased more frequently, spent more monthly clothing expenses, and used the internet. Clothing store attributes were considered more important by female students than the other attributes. In these results, clothing benefits were identified as consumer characteristics of female Uzbek college students and market segmentation was determined. In addition, it is meaningful in providing basic data for efficient marketing activities and minimizing trials and errors in establishing local-friendly strategies for target customers in different cultures.

The meticulous figure painting is one of the wonders of traditional Chinese painting and has blossomed in art history with its unique and interesting style. The period from the Warring States period to the Song and Yuan dynasties was a glorious period in its history, after which it tended to decline due to changes in painting materials and many socio-historical reasons. The extensive cultural exchanges in the world today, the penetration of Western values and the expansion of information technology have brought a huge impact on Chinese meticulous figure painting, which has developed an active way of thinking and expression after absorbing certain elements of Western culture and thought on the basis of inherited tradition. Contemporary Realistic Figure painters continue to explore new developments in meticulous figure painting in the contemporary context, and give contemporary meticulous figure painting a new cultural and ideological connotation, forming a new look that meets the requirements of the times, with richer and more lively content, subject matter and formal language. Traditional meticulous figure painting is characterised by a highly refined use of line and coloring composition. Contemporary meticulous figure painting focuses on the use of purely formal language and the expression of the personality of the creative subject, with a new outlook on the world of painting. In the contemporary multicultural context, new formal language and methods of expression are constantly being explored to create a new look. In the process of development, contemporary meticulous figure painting has merged the best qualities of traditional and contemporary culture, making it an art with a subtle language, rich in meaning and with the charm of the times and oriental characteristics. The author in the form of contemporary fine brushwork figure painting language as the research object, explore new form of fine brushwork figure painting, and in the contemporary society and multicultural context factors. Innovation, enrich and develop new forms of art language of contemporary social form and aesthetic temperament and interest.

창의성이 조직의 성장과 발전에 중요하다는 점에서, 많은 기업들이 조직원의 창의성을 높이기 위한 방안들을 모색하고 있다. Dual pathway to creativity model 에 관련된 기존 연구에 따르면, 창의성은 두 가지 경로(인지적 유연성 혹은 인지적 지속성)를 통해 향상된다고 알려져 있다. 그러나, 이 두 가지 경로가 어떻게 활성화 되는지 이해하는데 있어서 조직원의 개인적 특질이 고려되어야 함에도 불구하고, 유연성과 지속성 중 어느 경로가 특정 성격에 더 효과적 인지에 대해서는 거의 논의된 바가 없다. 본 논문에서는, 애착 이론에 근거하여, 개인이 가진 애착 유형이 두 가지 인지적 경로에 어떤 영향을 미치는지 살펴보았다. 구체적으로, 안정 애착을 가진 개인이 (인지적 지속성이 아닌) 인지적 유연성 경로를 사용했을 때, 창의성이 향상된다고 예측하였다. 미국 피험자를 대상으로 한 온라인 실험은 본 연구의 가설을 지지하고 있다. 본 연구의 결과는, 조직 내 창의성 향상에 있어서 안정 애착이 (인지적 지속성이 아닌) 인지적 유연성과 더 적합하다는 점을 시사하고 있다.

중국 애니메이션은 1950년대와 80년대의 황금기를 거치면서, 중국의 전통문화를 계승한 민족적 스타일을 형성하였고 다양한 제작 방식과 민족적 정신을 고수하였다. 그러나 오늘날 중국 애니메이션은 세계의 애니메이션과 경쟁하면서 다양한 도전에 직면하고 있다. 이러한 상황 속에서 중국 애니메이션은 '중국 문화의 정체성'을 어떻게 확립하고 중국의 고유한 민족성을 어떻게 현대적 성격과 결합할 것인가에 대해 고민해야 하는 시점에 와 있다. 본 연구는 중국 애니메이션 작품 속에 나타난 중국 전통 색채관의 상징성과 심미특징을 분석하는 것을 통해 상징성과 심미특징이 어떻게 사용되었는지, 그리고 의경미(意境美)가 어떻게 나타나고 있는지를 분석하는 것을 목적으로 하고 있다. 이를 통해 중국 전통 색채가 오늘날 현대 중국 애니메이션의 미래 방향과 가치를 제시하는데 있어, 창조적 요인으로 작용 가능한지를 본 연구를 통해 알아보고자 한다.

연환화(連環畵)는 중국 만화사 초기에 발생하여 회화와 서사가 결합한 중국의 독특한 문예 양식으로 발전하였다. 또한 중국 만화사에서 연환화와 만화는 한때 형식이 융합되는 경향도 있어 1920년대에는 만화 스타일로 창작된 연환화가 매우 유행하기도 했다. 이를 연쇄 만화라고도 부른다. 1950-1960년대에 중국 연환화는 독립적으로 발전해 고유한 형식적 특징을 나타내기에 이르며 기법적으로도 성숙한 '황금시기'를 맞았다. 이 시기 연환화 작품은 서사의 극적 표현, 보다 현실적인 인물 묘사를 보여주며 표현수법 및 예술양식 등은 매우 큰 발전을 거두었으며 작품의 예술적인 완성도가 크게 높아졌다. 허유즈(賀友直)의 "산향거변(山鄕巨變)"과 화싼촨(華三川)의 "백모녀(白毛女)"가 예술성과 완성도 면에서 손꼽히는 이 시기의 대표작이다. 제2장에서는 중국 연환화의 기원 및 발전에 대해 살펴보았는데, 이를 통해 중국 연환화가 매 시기 내용과 형식의 결합에서 새로운 성과를 거두었다는 사실을 알 수 있었다. 또한 중국 연환화의 발전 과정에서 1950-1960년대의 작품들이 예술성과 완성도 면에서 가장 큰 성과를 거두었다는 사실을 확인했다. 따라서 제3장에서는 중국 연환화의 '황금시기' 대표작인 "산향거변"과 "백모녀"의 구체적인 이미지를 다각적인 각도에서 분석함으로써 서사의 극적 표현, 현실적인 인물 묘사 등이 어떻게 구체적인 예술성을 획득했는지 보여주고자 했다. 분석은 인물의 성격 묘사, 화면 구도, 배경 및 기법의 활용, 연출 방식 등에 대해 중점적으로 이루어졌다. 이 두 작품을 연구한 목적은 구체적인 작품의 분석을 통해 훌륭한 연환화의 조건을 확인하고, 연환화의 회화 기법 및 연출 구도 등 예술적 성과가 중국의 초기 만화에 끼친 영향을 고찰하는 데 있다. 이 두 작품은 현실적인 삶의 모습을 담아내는 데 주력하며 내용을 전달하는 데 보다 효과적인 표현을 창조하고자 새로운 연출과 기법을 시도하였다는 의의를 지닌다. 또한 동양과 서양 회화의 미학적인 장점을 두루 흡수하여 작가 나름의 개성이 돋보이는 새로운 스타일을 완성하였다는 점에서 그 성과가 돋보인다. 두 작품은 표현 형식과 회화 기법에서 차이를 보이지만 모두 중국적인 삶의 짙은 정취와 '민간(民間)'의 분위기를 자아낸다는 공통점을 지닌다.

화자인식은 자동 음성시스템에서 중요한 기능을 담당하며, 최근 휴대용 기기의 발전 및 음성 기술, 오디오 콘텐츠 분야 등이 계속해서 확장됨에 따라 화자인식 기술의 중요성은 더구나 부각 되고 있다. 이전의 화자인식 연구는 음성 파일을 기반으로 화자가 누구인지 자동으로 판정 및 정확도 향상을 위한 목표를 가지고 진행되었다. 한편 말투는 중요한 사회언어학적 소재로 사용자의 사회적 환경과 밀접하게 관련되어 있다. 추가로 화자의 말투에 사용되는 종결어미는 문장의 유형을 결정하거나 화자의 의도, 심리적 태도 또는 청자에 대한 관계 등의 기능과 정보를 가지고 있다. 이처럼 종결어미의 활용형태는 화자의 특성에 따라 다양한 개연성이 있어 특정 미확인 화자의 종결어미의 종류와 분포는 해당 화자를 인식하는 것에 도움이 될 것으로 보인다. 기존 텍스트 기반의 화자인식에서 말투를 고려한 연구가 적었으며 음성 신호를 기반으로 한 화자인식 기법에 말투 정보를 추가한다면 화자인식의 정확도를 더욱 높일 수 있을 것이다. 따라서 본 연구의 목적은 한국어 화자인식의 정확도를 개선하기 위해 종결어미로 표현되는 말투(speech style) 정보를 활용한 방법을 제안하는 것이다. 이를 위해 특정인의 발화 내용에서 등장하는 종결어미의 종류와 빈도를 활용하여 벡터값을 생성하는 문장 시퀀싱이라는 방법을 제안한다. 본 연구에서 제안한 방법의 우수성을 평가하기 위해 드라마 대본으로 학습 및 성능평가를 수행하였다. 본 연구에서 제안한 방법은 향후 실존하는 한국어 음성인식 서비스의 성능 향상을 위한 수단으로 사용될 수 있으며 지능형 대화 시스템 및 각종 음성 기반 서비스에 활용될 것을 기대한다.

전라북도 정읍은 한국 사상사에서 주목을 요하는 지역이다. 또한 정읍은 문학사에서 '최초'를 기록한 작품이 많은 지역이다. 백제 노래 <정읍사>가 그렇고 조선시대 사대부 가사 <상춘곡>이 그렇다. 그리고 이 지역 태수를 지낸 최치원(857~?)의 선정과 풍류의 전통이 전해오는 고장이기도 하다. 이 논문에서는 정읍의 무성서원의 성립과정과 선비문화에 있어서 최치원의 연관성을 살펴보았다. 최치원이 임기를 마치고 떠날 때 고을 사람들이 선정에 보답하는 의미로 태산사라는 생사당을 건립하였고 그것이 근원이 되어 후대에 무성서원으로까지 이어졌다. 최치원은 자신의 포부와 역량을 정읍에서 실현하였다. 특히 조선중기 무성서원의 건립과 사액 과정에 최치원의 역할은 결정적이었기에 최치원은 이 지역의 상징적 인물로 되살아날 수가 있었다. 그리고 무성서원을 중심으로 영정의 이안(移安) 작업을 통해서 최치원의 형상도 보다 유학자, 유학적 선비의 모습으로 좌정해나가는 것도 볼 수가 있다. 최치원이 남긴 시문을 통해서도 유학적 선비(지식인)로서 자각을 읽을 수 있다. 그의 시세계가 다양하지만 특히 유학자 지식인으로서 현실에서 오는 시름과 고뇌, 비판적인 내면의식 등을 표출한 작품이 많은 수를 차지하고 있음을 볼 수 있다. 최치원은 남다른 포부와 각고의 노력으로 당대의 우뚝한 문사로서의 자질을 유감없이 발휘하기는 하였으나, 그 자신 주변국의 한 시인으로서의 지역적, 정신적 소외감을 극복하지 못했다. 따라서 세계인식 면에서의 치열성은 자연히 내면화될 수밖에 없었다. 그러나 그것이 오히려 그의 작품으로 하여금 강한 서정성을 가지게 한 요인이 되었던 것으로 보인다. 그리고 최치원의 문집에는 당대의 말기적 현상에서 초래된 다양한 형태의 병리적 현상을 강한 어조로 비판한 작품들이 다수 포함되어 있다. 그는 가난하고 곤고한 삶을 살아가는 민중들의 모습을 사실적으로 그려내는가 하면, 왜곡된 생산관계 속에서 결국 희생되고 마는 가련한 백성들의 삶의 실상을 형상화함으로써 당대의 잘못된 사회의 단면을 부각시키기도 했다. 이러한 것은 지식인으로서의 고뇌로 읽을 수 있다. 선비의 사전적 정의가 '학식과 인품을 갖춘 사람에 대한 호칭으로, 특히 유교이념을 구현하는 인격체 또는 신분계층을 가리키는 유교용어'이고, 오늘날 의미로는 '신분적 존재가 아니라 인격의 모범이요, 시대사회의 양심으로서 인간의 도덕성을 개인 내면에서나 사회질서 속에서 확립하는 원천으로 이해될 수 있다.'고 할 때, 최치원의 문학에서 고뇌하는 모습은 곧 선비(지식인)의 고뇌이고 '선비(士)'로서의 책무를 자각하였기에 나오는 반응이라고 할 수 있다. 그러한 점에서 최치원은 가장 이른 시기의 선비(지식인)의 원류라고 보아도 크게 잘못이 없을 것이다.

Though the tradition of Korean mathematics since the ancient time up to the 'Enlightenment Period' in the late 19th century had been under the influence of the Chinese mathematics, it strove to develop its own independent of Chinese. However, the fact that it couldn't succeed to form the independent Korean mathematics in spite of many chances under the reign of Kings Sejong, Youngjo, and Joungjo was mainly due to the use of Chinese characters by Koreans. Han-gul (Korean characters) invented by King Sejong had not been used widely as it was called and despised Un-mun and Koreans still used Chinese characters as the only 'true letters' (Jin-suh). The correlation between characters and culture was such that, if Koreans used Han-gul as their official letters, we may have different picture of Korean mathematics. It is quite interesting to note that the mathematics in the 'Enlightenment Period' changed rather smoothly into the Western mathematics at the time when Han-gul was used officially with Chinese characters. In Koryo, the mathematics existed only as a part of the Confucian refinement, not as the object of sincere study. The mathematics in Koryo inherited that of the Unified Shilla without any remarkable development of its own, and the mathematicians were the Inner Officials isolated from the outside world who maintained their positions as specialists amid the turbulence of political changes. They formed a kind of Guild, their posts becoming patrimony. The mathematics in Koryo significant in that they paved the way for that of Chosun through a few books of mathematics such as 'Sanhak-Kyemong', 'Yanghwi-Sanpup' and 'Sangmyung-Sanpup'. King Sejong was quite phenomenal in his policy of promotion of mathematics. King himself was deeply interested in the study, createing an atmosphere in which all the high ranking officials and scholars highly valued mathematics. The sudden development of mathematic culture was mainly due to the personality and capacity of king who took anyone with the mathematic talent into government service regardless of his birth and against the strong opposition of the conservative officials. However, King's view of mathematics never resulted in the true development of mathematics perse and he used it only as an official technique in the tradition way. Korean mathematics in King Sejong's reign was based upon both the natural philosophy in China and the unique geo-political reality of Korean peninsula. The reason why the mathematic culture failed to develop continually against those social background was that the mathematicians were not allowed to play the vital role in that culture, they being only the instrument for the personality or politics of the king. While the learned scholar class sometimes played the important role for the development of the mathematic culture, they often as not became an adamant barrier to it. As the society in Chosun needed the function of mathematics acutely, the mathematicians formed the settled class called Jung-in (Middle-Man). Jung-in was a unique class in Chosun and we can't find its equivalent in China or Japan. These Jung-in mathematician officials lacked tendency to publish their study, since their society was strictly exclusive and their knowledge was very limited. Though they were relatively low class, these mathematicians played very important role in Chosun society. In 'Sil-Hak (the Practical Learning) period' which began in the late 16th century, especially in the reigns of Kings Youngjo and Jungjo, which was called the Renaissance of Chosun, the ambitious policy for the development of science and technology called for. the rapid increase of he number of such technocrats as mathematics, astronomy and medicine. Amid these social changes, the Jung-in mathematicians inevitably became quite ambitious and proud. They tried to explore deeply into mathematics perse beyond the narrow limit of knowledge required for their office. Thus, in this period the mathematics developed rapidly, undergoing very important changes. The characteristic features of the mathematics in this period were: Jung-in mathematicians' active study an publication, the mathematic studies by the renowned scholars of Sil-Hak, joint works by these two classes, their approach to the Western mathematics and their effort to develop Korean mathematics. Toward the 'Enlightenment Period' in the late 19th century, the Western mathematics experienced great difficulty to take its roots in the Peninsula which had been under the strong influence of Confucian ideology and traditional Korean mathematic system. However, with King Kojong's ordinance in 1895, the traditional Korean mathematics influenced by Chinese disappeared from the history of Korean mathematics, as the school system was hanged into the Western style and the Western mathematics was adopted as the only mathematics to be taught at the Schools of various levels. Thus the 'Enlightenment Period' is the period in which Korean mathematics shifted from Chinese into European.
