Purpose: The purpose of this study is to investigate the epithelial-mesenchymal transition (EMT) induced by Snail transcription factor and Snail-transfected in vivo tumors with histopathological features. Materials and methods: We induced in vivo xenografted tumorigenesis in the oral vestibules of nude mice by a Snail transfected HaCaT cell line and investigated morphological and immunohistochemical features in Snail expressive tumors. Results: We identified tumor masses in 14 out of 15 nude mice in the HaCaT-Snail cell inoculation group, but no tumors were present in any of the HaCaT cell inoculation group. Induced tumors showed features of poorly differentiated carcinoma with invasion to neighboring muscles and bones. The HaCaT-Snail tumors showed decreased expressions of E-cadherin and cytokeratin, but showed increased expressions of vimentin and N-cadherin. Discussion: The Snail transfected xenograft can improve productivity of malignant tumors, show various histopathological features including invasive growth, and aid in the investigation of tumor progression and the interaction with surrounding tissues.

As ongoing construction of a new municipal government building leads to the destruction of the interior of the Kyungsung Municipal Government Building(currentlySeoul Metropolitan City Hall) despite its enormous historic value, this study aims to identify the unique features of spatial composition and interior design of the Kyungsung Municipal Government Building, which is widely known as a typical example of public architecture of the 1920s. The primary goal is to perform a systemic arrangement of its interior data and define the modern historic implications of its interior design, thereby laying the foundation for a compilation of the history of modern interior design. From a historical perspective, the Kyungsung Municipal Government Building-an explicit symbol of Japanese colonial supremacy-has served as the administrative hub of a hugecity for 19 years during the Japanese colonial rule and for 64 years following Korea's independence from Japan. From the perspective of architectural history, it also represents modern transitional buildingsin their shift from historicism into modernism, as manifested by its reasonable placement of interior space matching well with topographical form, easy access by citizens, open office space, and, excluding decoration, a simple and non-authoritarian exterior. Its interior design style follows Western historicist architecture, whereasits simple interior decoration embodies expressive characteristics of pragmatic simplicity. Such elements are notably found in the Grand Central Hall, the Municipal Head's Reception Room, and the Grand Conference Room.

This paper aims to examine the fundamental relationship of what principles cause the aesthetic shapes in Korean sarangbang furniture of the $19^{th}$ century. Focusing on the Greimas' isotopic and semantic structure analysis, this research analyzed the traditional Korean men's furniture in four steps; signifier analysis, isotopic analysis, semantic structure analysis, and comprehensive interpretation. The results show that the expressive qualities of sarangbang furniture included visual symmetric aesthetics, and the hues of natural materials with dark tones. The manufacturing process emphasized the characteristics of natural materials; while diversity was respected in decorations, function as restrained form was also important with a concise image. Through these characteristics, sarangbang furniture revealed a balance, a harmony of contrastive elements, and a restrained aesthetics. Within these qualities, it was seen that aesthetic principles, such as "severance and communication," "artifice and nature," "restraint and manifestation," "toughness and softness," "filling and emptying" and "decoration and utility" were in a mutually supplementary relationship. At the basis of this aesthetic thought appears to be Confucianism, which had been the model for seonbi politics and scholarship.

There had been studied for a function of fashion illustration that has various capability of differentiation among fashion products since year 2000. A fashion products adopted the illustration is stand out not only to increase the goods profits by consumers who is willing to purchase the products with specified identity but also to execute differentiation strategy in a market. The aim of this study is the theoretical approach of fashion illustration and examined the development process of the products based on the supporting documents of cooperations, other records and actual application cases. Also, expression techniques of fashion illustration, image features and etc. are mainly studied and following representative results are projected through the data. First, the success of fashion commercialization using fashion illustration should have mutual organic function which requires three factors such as product project, marketing, the role of illustration. Second, An illustration of hand drawing expression technique is more helpful in differentiation of fashion product than using computer graphic, embroidery, collage technique and the fashion products vividly expressed with sensuous illustration tend to have higher preference. Third, the possibility of success the fashion products is often affected by the distinct identification and the precise positioning while the illustration is used.

Content-based image retrieval system retrieves an image from a database using visual features. Among approaches to express visual aspects in queries, 'query by sketch' is most convenient and expressive. However, every 'query by sketch' system has the query imperfectness problem. GContent-based image retrieval system retrieves an image from a database using visual features. Among approaches to express visual aspects in queries, 'query by sketch' is most convenient and expressive. However, every 'query by sketch' system has the query imperfectness problem. Generally, the query image produced by a user is different from the intended target image. To overcome this problem, many image retrieval systems use the spatial relationships of the objects, instead of pixel coordinates of the objects. In this paper, a query-converting algorithm for an image retrieval system, which uses the spatial relationship of every two objects as an image feature, is proposed. The proposed algorithm converts the query image into a graph that has the minimum number of edges, by eliminating every transitive edge. Since each edge in the graph represents the spatial relationship of two objects, the elimination of unnecessary edges makes the retrieval process more efficient. Experimental results show that the proposed algorithm leads the smaller number of comparison in searching process as compared with other algorithms that do not guarantee the minimum number of edges.

In this paper we describe a new data modeling language we call $O^{2}LDM$. $O^{2}LDM$ incorporates features from object-oriented and logic approaches. In $O^{2}LDM$ there is a rich collection of objects organized in a type hierarchy. It is possible to compose queries that involve field selection, function application and other constructs which transcend the usual, strictly syntactic, matching of PROLOG. We give the features of $O^{2}LDM$ and motivate its utility for conceptual modeling. We have a prototype implementation for the language, which we have written in ML. In this paper we describe an executable semantics of the deductive process used in the language. We work some examples to illustrate the expressive power of the language, and compare $O^{2}LDM$ to PROLOG.

This study examined the images and formative features of female characters portrayed in fantasy films. This study aimed at providing an applicable theory to modern fashion by reconsidering the images of women appearing in fantasy films and arranging fantastical features reflected in costumes of female characters. The followings were the results of the study: The first divine nature that human beings discovered was woman nature. The discovered stone worked of the prehistoric age had a meaning of the great mother of universe and expressed a positive image. Such positive images of the goddess were variously differentiated to negative images or reduced in their roles and meanings in the settlement process of patriarchy as well as sociocultural transition. The foremost examples of negative image were expressed as grotesque, destructive, otherness, sensual, and exotic. The positive image of a goddess in fantasy films was not especially emphasized. On the other hand, the negative images of the goddess and the case of costumes were variously expressed as well as emphasized the typicality of the negative image of the characters. It was reconsidered that the typical features of characters in fantasy films were a result of the image of women following sociocultural transition. In addition, it was confirmed that such result was being reflected in film costume.

The aim of this study is to identify the formative feature of the Chippendale style of the 18th century and to understand the aesthetic feature of the Chippendale style applied in the modern fashion. This is significant in that new possibilities are proposed in fashion design in more holistic and multifaceted views by comparing and delving into the fashion vis-a-vis other fields in a bigger scope of the formative art. The Chippendale style furniture is a combination of various styles of different eras and regions such as Gothic and Chinese style based on the Rococo style. Today, It is regarded in fashion as a composite design of heterogeneous elements or very curvy decorative design. The Chippendale style of this kind is classified into the Rococo style, Gothic style and Chinese style. Depending on each classification, formative features including curves, asymmetry, decorativeness, geometrical feature, exoticism, compositeness and graceness were derived. In comparative studies, fashion and furniture of the Chippendale style have the similarity in formative features but there were some differences in the expressive method. This study analyzed the formative features of the Chippendale style represented in furniture and the modern fashion based on the Rococo-revival design in the modern fashion starting from 2000.

The concept of the modern consumption is not limited to the value of use by mere purchasing and using of the products. The consumers in modern capitalistic society, consumes the semiotic value whose meaning is socially granted, as well as the value for using. Therefore, that tendency that the symbolic sign of the products is consumed to differentiate oneself from the others and express oneself appears. The designed hotel that reflects the features of sign consumption in the modern society and where the discriminate experience can be enjoyed through the unique and diversified design expression is drawing our attention. Therefore, in this paper, based on the theoretical consideration of semiotics, the tendency of sign consumption and its feature appearing in the modem society has been studied. And through the case studies of the hotels which have been built since the 2000s, how such features can be expressed in the space has been studied. As a result of the study, as for the features of expression of modern semiotic consumption society shown in the design hotels, the diversity breaking from the uniformity by the diversified thinking, the hybrid attribute, and the attribute of the differentiated entertaining images, based on hedonism, the inherent symbols and narrative attribute, and the flexible interactions through the experience of emotional consumption, are appearing.

Although evolution of construction materials brought about development of modern architecture, they caused destruction of the environment and pollution. This problem is not a new one in terms of ecological esthetics and materials of sustainable architecture in light of the Eastern view of nature and this idea became a background of this study. The basic concept is to try to find out their characteristics from a perspective of ecological esthetics in relation to traditional building materials that nature, architecture, and humans coexist and live with each other to balance. Based on ecological esthetics and precedent studies on materials of traditional architecture, we investigated connections, expressive methods and characteristics in traditional residential construction space. This attempt has meanings in that it can propose a new framework of forming various viewpoints and spatial perceptions in relation to esthetics and traditional construction materials. The current study examined the characteristics by dividing them into tangible and intangible elements based on expressive features of elements of nature. The characteristics found by this process are not simply notion of physical materials, but plays a key role aesthetically and ecologically. Nature and materials take circulation of the law of nature, regulate energy, increase efficiency and play a major role in an economic way. Nature in itself becomes natural alternative energy, and plays its role in an invisible fashion. It examined how expressive characteristics of construction materials are reflected through analyzing residential space and Korean traditional garden having relationships with Eastern viewpoint of nature in relation to Korean traditional construction materials from a perspective of ecological esthetics. Findings of the above study indicate that expressive characteristics of Korean traditional construction materials from a perspective of ecological esthetics are that nature, space, humans coexist and live together and they will provide a clue to an alternative to solve ecological and environmental problems modern society will have in the future. Through this process, it provided a possibility that traditional space and materials can be succeeded in creative and new ways, and it found out the way for nature, space, and humans to coexist and a possibility of ecological esthetics. It addition, it will provide a key base as an alternative of sustainable design of the future.
