Stimulated polariton scattering from the $B_1$-symmetry modes of a $KNbO_3$ crystal to generate a terahertz wave (THz-wave) with a noncollinear phase-matching scheme is investigated. The frequency-tuning characteristics of the THz-wave by varying the phase-matching angle and pump wavelength are analyzed. The expression for the effective parametric gain length under the noncollinear phase-matching condition is deduced. Parametric gain and absorption characteristics of the THz-wave in $KNbO_3$ are theoretically simulated. The characteristics of $KNbO_3$ for a terahertz parametric oscillator (TPO) are compared to those of $MgO:LiNbO_3$. The analysis indicates that $KNbO_3$ is an excellent optical crystal for a TPO, to enhance the THz-wave output.

컴퓨터에 의해 촉발된 디지털 미디어 기술은 그 발전 속도가 나날이 가속화되어, 현재는 과학기술 분야뿐만 아니라 사회 문화적으로 확장되어 커다란 영향력을 갖게 되었다. 이러한 확장과 영향력에 대해 국내에서는 '디지털 컨버전스'라는 용어로 축약되어 설명될 수 있는데, 에드몽 꾸쇼(Edmond Couchot)는 'hybridization' 이라는 용어로 설명한 바 있다. 슈필만과 볼터(Yvonne Spielmann and Jay David Bolter)는 이러한 혼성적인 디지털 미디어 작품들은 이미지, 텍스트, 사운드, 공간 그리고 구체적 표현 방법 등의 다양한 범위의 재현 형식을 넘나들며 통합되고 있다고 하였으며, 이러한 혼성적인 특성 중 실재(real)적인 것과 가상(virtual)적인 것의 융합으로 인해 이루어지는 상호소통에 대해 다루어야 함을 역설한 바 있다. 본 논문에서는 실재와 가상이 융합된 결과물의 형태로 보여지는 혼합 현실 환경에 주목하여 이러한 적극적인 상호소통을 필요로 하는 양극의 주체인 과학기술과 문화예술간의 적절한 접점으로 수렴되고 있는 분야 중의 하나인 혼합현실형 공공 문화콘텐츠를 예를 들어 미디어아트에서 시도되었던 방법들과 그에 대한 확장된 해석을 통해 과학과 예술을 현대적으로 화합시키는 방법에 대한 연구를 통해 과학과 예술의 수렴을 지향하는 간학제적 관점을 논구하고자 한다.

Narrative has broad domains. So it is related to the everything man faces in his daily life and also performed in various modes. Narrative is revealed through all media including a character, which is also applied to plastic art. And narrative objects formed beyond the differences in media aid forms of expression are commonly based on a language. The study on such objects which created a new conceit of narratology can be said to be a spiritual trend by which to understand the world and man from the viewpoint of a 'story'. Plastic art took high interest in narrative in the same period as the rise of postmodernist art in the latter half of the 20th century, which was also applied to sculpture. The researcher, therefore, investigated through the history of sculpture in the 20th century the process in which narrative was denied under the value system of modernism and reappeared with the quickening of postmodernism. And as a result this period could be briefly characterized by 'return to figure' and 'reappearance of narrative'. The is, such flow means that late sculpture converted its center of interest from simple geometric abstract forms to irregular, figurative images. The researcher chose as the subject of his study the work of Louise Bourgeois, who was judged to have performed narrative positively and successfully among a great number of performed narrative positively and successfully among a great number of postmodernist sculptors who adopted it as their own strategy of expression. As the central artist of postmodrnist sculpture, She expressed human desire and condition as sexuality through the introspection of her own personal experience in contrast to the character of pop art sensitive to external world. The researcher borrowed narrative semiotics as a method of analyzing more elaborately the problem about the generation of narrative shown in her works. For it, he selected as the sample work for analysis Bourgeois's , which were judged to contain narrative most abundantly and as the metaphor of a gaze and recollection presented a new woman self that sublimed love, hatred, and loneliness. The narrative in her works are characterized by introspection questioning one's own trauma. It has independent domain and characteristics and clearly reveals narrative and content-centered characteristics, which are commonly discovered in postmodernist sculpture. The researcher could more concretely and definitely understand the characteristics of narrative through figurative images by analyzing the sample work. The researcher wanted to call your attention to the fact that the sculpture in the late 20th century contained narrative commonly and uniformly despite being characterized by various expressions and modes. And the focused on highlighting the fact that the narrative was more effectively revealed through figurative images of human body and simultaneously analyzing the formalizing process and structure for narrative. Besides he wanted to argue that the position of narrative defining the characteristics of sculpture should be valued more justly. Also, such acceptance of narrative, which is discovered in the sculpture, will have to be understood as the characteristics of the period reflecting the cultural aspect of the present time.

Purpose : Phospholipase C(PLC) isozymes play significant roles in transmembrane signal transduction. PLC-${\gamma}1$ acts as the intracellular effector in signal transduction for cellular proliferation and differentiation. Ras oncoprotein is also involved in cell growth. We determined the biological significance of PLC and ras oncoprotein in regeneration following radiation and the effect of different modes of administration of 5-FU. Materials and Methods : To determine the effect of the administration mode of 5-FU on the regeneration of intestinal mucosa of rats following radiation, we compared the expression of PLC and ras oncoprotein in six groups. Group I had no treatment. Group II received radiation(8 Gy) only. Group III received radiation(8 Gy) and 5-FU(150mg/kg) continuous intravenous (iv) infusion for 12 hours. Group IV received radiation(8 Gy) and 5-FU(750mg/kg) iv bolus injection. Group V received only 5-FU(150mg/kg) continuous iv infusion for 12 hours, Group VI received only 5-FU (150mg/kg) iv bolus injection. Through immunoblotting and immunohistochemistry, we examined the expression of PLC and ras oncoprotein in rat jejunum at 96 hours after radiation or 5-FU administration and at 120 hours after radiation and 5-FU adminstration. We also investigated the histological findings using hematoxylin and eosin stain. Results : In the immunohistochemistry study, PLC-${\gamma}1$ expression was the highest in group III followed by groups II and VI in that order and was weakly positive in groups V and VI. PLC-${\gamma}1$ was hardly detected in the control group. The expression of ras oncoprotein was the same as the PLC-${\gamma}1$ expression for all groups. These results were confirmed by the histological findings regarding the mucosal regeneration. In the immunoblotting analysis, PLC-${\gamma}1$ expression was the highest in group III followed by group IV and II in that order. This difference between the immunoblotting and immunohistochemistry study was due to the high expression of PLC-${\gamma}1$ on the damaged surface epithelium rather than to its expression in the regeneration region as observed in the immunohistochemistry study for group IV. The expression of PLC-${\delta}1$ was positive only in group V and VI, which received both radiation and 5-FU, and the expression of PLC-${\beta}1$ was negligible for all groups. Conclusion : These results suggest that PLC-${\gamma}1$ mediated signal transduetion and ras oncoprotein may have a significant role in mucosal regeneration after radiation, and that continuous iv infusion of 5-FU may induce active regeneration in intestinal mucosa following radiation. In addition, the expression of PLC-${\delta}1$ in combined group of radiation and 5-FU implies that PLC-${\delta}1$ may be involved in signal transduction mediated by concerted action between radiation and 5-FU.

The multilateral attempt for present applications of art school of thought and expression is leading modern fashion as a chapter of various artistic expression. In fashion, historic art thinking which predominated the period are source of optional inspiration not simply being generated, culminated and disappear but layout principles which can reemerge as periodical needs. In other words, the past styles are the source of inspiration of new trend of the present time and will serve as the text that give birth to yet another trend. In this study, I conducted the research on the layout principles of Modernism Architecture in aspects of pure visibility and the layout characteristics. And I analyzed cases of modern fashion which were appling architectural layout principles in the view point of formal construction dimension. As the result, the layout principles of Modernism Architecture have the characteristics of diagram linearity, geometric planarity and exclusive closing. And I was applying the architectural layout principles of Modernism to fashion. The layout principles of Modernism Architecture have the tendency of lacking history types, abstract plane partition and reductionism purity in fashion. The meaning of this study is follows: The characteristics of art school of thought are given shape by appling & analysing the architectural layout principles of historical art school of thought to modern fashion in the view point of formal construction dimension. The applied possibility of historical art school of thought as the source of inspiration about the fashion design is extended.

The development of the Internet has led to the emergence of an internet meme culture using duplication. This phenomenon has appeared in the fashion field as 'fashion memes' and its playful expression has helped it to spread. Vetements is one of the well-known brands that actively incorporates fashion memes into their fashion. The purpose of this study was to examine the playfulness of Mikhail Bakhtin's Carnival Theory and identify the playful identity, design characteristics, and implications of Vetements' fashion memes in light of Bakhtin's playfulness. The research methods were literature research and collection case analysis, and empirical content research was conducted in parallel. The scope of this study was fashion memes shown in the products from 2017 S/S to 2019 F/W. The study results showed that Bakhtin's playfulness could be divided into "playfulness in the destruction of hierarchy", "playfulness in grotesque imagery" and "playfulness in the emphasis on the lower bodily stratum". Based on these findings, the playful identity of Vetements' fashion meme images can be described as follows. First, it breaks down the existing order of fashion brands like the destruction of hierarchy in Bakhtin's theory. Second, it is grotesque; it is strange, eerie, yet ridiculous at the same time. Third, it is a playful metaphor of contamination, filth, and lower stratum. The modes of embodiment of such identity include Vetements' collaboration with famous brands, the use of cheap items, and the expression of genderless ideas.

만화는 말과 그림 그리고 칸의 흐름이 복합적으로 구성되면서 의미를 표출하는 장르이다. 만화를 그린다는 것은 언어와 시각언어의 합성을 통해 그 의미가 수용자 즉, 만화를 읽는 사람에게 어떻게 전달되는가를 의미한다. 즉, 만화를 읽고 만화로 표현하는 행위는 시각적 커뮤니케이션에 대한 이해를 바탕으로 이루어지므로, 기호학을 바탕으로 하는 시각적 커뮤니케이션에 대한 학습은 만화교육에서 매우 중요하다. 본 논문에서는 다양한 분석방법 가운데 특히, 기호학을 바탕으로 하는 연구사례를 중심으로 만화교육을 위한 기호학적 방법론을 검토하였다. 연구사례는 크게 1) 형식에 대한 분석사례, 2) 내용에 대한 분석사례, 3) 형식+내용에 대한 분석사례의 세 가지 영역으로 구분하여, 기호학의 관점에서 실질적으로 이루어진 만화분석 사례를 토대로 만화 교육에의 적용방법과 역할을 제안해 보고자 한다. 기호학의 관점에서 이루어진 분석들은 연구자의 주장을 객관적으로 제시할 수 있다는 공통점을 가지므로, 기호학적 방법론을 응용한 교수학습법 개발과 수업에서의 활용효과 등에 관한 연구가 적극적으로 이루어져, 보다 체계적인 만화교육의 기틀을 위한 또 하나의 방법으로 활용되길 바란다.

Fashion is changing and evolving everyday with an influence from and over contemporary socio-cultural factors. Cartoons expressing the phenomena of times through exchanges of mutual effects with socio-cultural factors that result from functionality and media characteristics. This study examines how fashion provides a great correlation with society-culture expressed in cartoons. The research segment of this study was conducted with literature and case studies; in addition, the UK cartoon magazine "Punch" was selected for the case study. The research findings of the fashion satire expression in cartoon were divided into 2 cases. The first case is that fashion was used as an instrument to satirize socio-cultural phenomena in cartoons. Various fashion elements (hats, dresses, words on T-shirts) were used for satiric expressions and to express periodic images related to politics, economics, society and culture. It communicated factually or criticized noteworthy phenomenon or age changes through the symbolism of fashion. The second case is that fashion itself is the object of satire in a cartoon. It satirically described the blind following and destruction of stereotype as direct objects. Fashion satire appeared in cartoons regardless of a correlation with age. Each cartoon fashion satire had meaning in both humor and criticism for satirizing the age. This study shows that fashion symbolism for satire of the reality has been used as the instrument of expression and simultaneously expressed as the object of the critique as an image and phenomenon that reflects reality. This study has significance in that it examined expressive modes of fashion satire in cartoons that escape from separating fashion from cartoon as a different area.
