The natural convection in a horizontal enclosure heated from the bottom wall, cooled at the top wall, and having a square adiabatic body in the center is studied. Three different Prandtl numbers (0.01, 0.7 and 7) are considered for the investigation of the effect of the Prandtl number on natural convection. Adiabatic boundary conditions are employed for the side walls. A two-dimensional solution for unsteady natural convection is obtained, using an accurate and efficient Chebyshev spectral methodology for different Rayleigh numbers varying over the range of $10_3$ to $10_6$. It had been experimentally reported that the heat transfer mode becomes oscillatory when Pr is out of a specific Pr band beyond the critical Ra. In this study, we reproduced this phenomenon numerically. It was found that when Ra=$10_6$, only the case for intermediate Pr (=0.7) reached a non-changing steady state and the low and high Pr number cases (Pr=0.01 and 7) showed a periodically oscillatory fashion hydrodynamically and thermally. The variation of time- and surface-averaged Nusselt numbers on the hot and cold walls for different Rayleigh numbers and Prandtl numbers are presented to show the overall heat transfer characteristics in the system. Further, the isotherms and streamline distributions are presented in detail to compare the physics related to their thermal behavior.

Recently, in the fields of fashion, advertisement, film, literature, philosophy, etc., the word, 'Nomad', is being used frequently across the overall society. The contemporary society is actively incorporating "nomadic thinking" as a new social phenomenon across the boundaries of conventional fields. This is not an exception in the field of space design. This study, via the contemporary nomadic thinking, examined the relationship between space design's application possibility as a new trend and flexible space; then categorized the characteristics of flexible space into flexibility, temporariness, changeability, and correlation; and then analyzed expression characteristics of flexible space. As for unrestricted expression of scene, it was recognized that separation of scene and space leads space to meet the needs of surrounding environment and users; formation of changeable space enables uses of space from various perspectives; and combining external factors (energy, media technologies) with space leads space to self-evolution. Space is perceived as an living organism that is flexibly corresponding, via realistic movement and virtual movement, to the indefinite, diversified thinking of the contemporary society. Therefore, this study illuminates that nomadic thinking has significance as basic thinking to predict development and characteristics of design thinking through understanding the contemporary society with the basic thinking system that has been inherent without restrictions of being fixed to the present, past, and future.

In considering the relationship between natural beauty and the human frame of mind, or the interconnections between the Landscape and the point of view, we are concerned primaily with the external factors. Historically, certain physical features tended to cause shifts in human attitudes toward landscapes; We concentrate on this phenomenon of changeful scenery rather than on what psychological factors caused certain landscapes to be regarded as remarkable or unique. In a similar fashion we must ask ourselves what the basic elements in landscape are and attempt to ascertain their visual and spatial characteristics before we attempt to desingn environments that are fundamentally, physical in character. Futhermore, the experience of meanings, a part of literatual association process, appeared through the intension of nature study looking for the best landscape phenomena out of simple naturelooking. Of course, as the variable degree of landscapes changes, the dualistic relationship between humans and objects shows the different experience of meanings as the time changes even in landscapes which possess variable factors in same season. The study is conducted by defining the nature of recognizing and appreciating the logical structure of the concept "Landscape" after analysis of meaning context appeared in 'Kyung' which is consists of time, space and elements in landscape.

The purpose of this study was to identify a basic meaning of humor from the costume expressing cartoon image, to grasp the status of contemporary costume, and also to supply people with a database related to the sphere of costume design. This was done by analyzing and examining humor of the costume expressing cartoon image in post-industrial society. Consequently, the result of this study was summarized as follows; First, humor by parody of Pop Art is recognized as humorous expression that repulsed the main current culture and post-industrial society phenomenon. Second, humor by quotation tends to appear through cartoon character. Costume which quote cartoon character is against Kidult tastes and the pre-existing authoritative prejudices in post-industrial society. Third, humor by bricolage, making bricolage with silhouette, color, pattern item, is recognized as new creation of humor In other words, it is regarded as enlargement of new esthetic consciousness and humor about instrumented gender in post-industrial society. Lastly, humor by deformation expressed itself in deformation of body image of character and cloth silhouette by cartoon image. Deformation of cloth silhouette by cartoon image, being not conscious pre-existing concept of harmony of human and costume, is recognized as humor which have characteristic of play with introduction of new silhouette. In addition to, the result of this study showed that humor expressed in cartoon image of costume has been limited to the works of few designers because of characteristics of fashion designers who made use of popularity as subjects of the works and internal meanings which were related to the characteristics of post-industrial society.

Clothing as one of elements of culture has been interwoven with cultural diffusion, and accompanied the most visible change. In this paper, it was focused that the process and the characteristics of western clothing adop-tion of Korea from 1876 to 1945 corelating with cultural diffusion theory. They were analyzed through the change of clothing reformation system by government, school uniform, and social phenomenon. The finding of this paper were as followings; 1. The process of western clothing adoption was forcibly demanded by Japan, therefore influenced by Japan. 2. The clothing reformation which was forced to accept western style was confronted by complex of cultural, psychological and economical resistance. 3. The fashion leaders of this period were Korean students studying abroad, diplomatic officials, members of the armed forces, government officials, students of western educational systemed school, and lady of evangelist. 4. Man adopted western clothing earlier than woman. 5. Western clothing adoption was took precedence in case of formal wear, diplomatic official's attire, military uniform, and school uniform. 6. In this process, we can find 'transculturation' by Malinowski and 'reinter-pretation' by Herskovits. 7. This process was a kind of 'reorientaion'. 8. The change of clothing which was affected by the tradition, for example, robe for the ancestral rites was evolutionary than others. 9. Clothing elements based on mental or internal characteristics like which clothing was hardly changed by compulsion or extortion. 10. The external trends of clothing change during this period were simplicity, utility, and decrease of status symbols.

This Study is on the Punggongyubodoryake. Punggongyubodoryak was the records and pictures written by Ohgyeongmun(吳景文, Painter) and Gangbonpungeon(岡本豊彦, a Japanese painter, 1773~1745). in 1832. Those records and pictures were about the gifts which Korea's King(宣祖, 1567-1608) sent to Doyotomi Hideyosi(豊臣秀吉, Pungsinsugil) in 1590. Most of the gifts were of the Korean costume, which meant that Korea recognized Doyotomi Hideyosi as the new general of Japan, Tokugawa Shogunate(幕府將軍). The pictures of every Clothing in punggongyubodoryake described forms of every cloth and delineated ornamental patterns and sizes of clothing as closely as actual, they were clothes of the Middle period of Chosun. the author of the study inferred that it would be one of the impotent materials in the history of the Korean traditional costume. Among the clothes, there were several danryeongs(단령, ceremonial coat), okgwan (玉冠 woman headdress with) and paeok(佩玉, pendents with jade stings) and choongdan(中單 ceremonial undercoat) and Sang(裳, ceremonial Skirts for man), gyeontongsuseulran (肩通袖膝襕, chinese coat) was recorded in punggongyubodoryake. they were not a set of clothes for ceremonial costume but a mixture of men's and women's costume, of korean and abroad styles. the author inferred that this phenomenon was actually a good proof that the gifts were sent to Hideyosi only as courtesy, which meant for downgrading the receiver.

This paper analyses the geometric aspect of Soma Delaunay's works on the basis of design elements and principles. Geometric pattern is one of the distinct features of early 20th century avant-garde works. The significance of its pattern and colour comes from the fact that it has not only influenced the contemporary fine art but also offered the basic principle of modern costume design. In 1925 she was designing clothes which could be worn today without appearing old-fashioned. She foresaw the future trends in fashion and interior decoration, One might claim she belongs to the avant-garde even today and no less astonishing a phenomenon than she was in 1925. Soma Delaunay's art was one of the first expressions of abstract painting and her "simultaneous contrasts"are among the earliest example of the aesthete. In Delaunay's geometric abstraction it is found that the technique of"simultaneous contrasts" is exploited almost without exception. colour as well as collage was the favourite technique Delnaunay used in creating a distinct simultaneity, Many "inobjective" paintings as she herself called unite the rigour of simple geometric forms with an inner life and poetry which emanate from the richness of the colour, the musicality of the rhythm, the vibrant breadth of the execution.rant breadth of the execution.

Today's technology enables consumers to trade millions of dollars, conduct online banking, access entertainment, and do countless other activities at the click of a button. Online social networks (OSN) have become a cultural phenomenon that allows for individualistic consumerism. Consumers are increasingly utilizing OSN to share ideas, build communities, and contact fellow consumers who are similar to themselves. The relevance of online communities to the music is immense especially because musicians are now using social media to build global audiences. Not only is information about music and performance disseminated online, but musical commodities are sold and traded online. Online music communities allow consumers to elect and create new identities online through the purchase of subcultural commodities. Given the growing economic importance of online music communities it is important to get a holistic view of subcultural communities online. This study utilized content analysis of online music community websites using the Netnography methodology as developed by Kozinet for data collection to analyze consumers' purchasing and consumption behavior of subcultural commodities online as related to the formation of subcultural identities. Findings showed that subcultural items are predominantly purchased online, especially digital music, and there is a need for more custom craft items. The authors presented a new conceptual taxonomy of online subcultural consumer classifications based on online behavior patterns.

As social recognition about men changes and men's concern about appearance increases, so in the social phenomenon of men's toiletries' diversification, ramification and specialization, the aim of this study is to analyze meaning of men's toiletries centered on men's toiletries advertisement published on men's fashion magazines which can be said to speak for men's culture. After collecting of 209 kinds of men's toiletries advertisements published in 'Esquire' and based on contents analysis results divided into domestic & foreign toiletries and perfumery, the symbolic analysis result with selection of representative advertisement in each field separately is that there are more cases of giving salience to a product through image expression rather than emphasizing product's function only, and the emphasis of image only achieves eminence in case of perfumery. At the comparison of domestic with foreign toiletries, in case of domestic toiletries, there are more cases of expressing meaning of toiletries through model image or backgrounds, while in case of foreign toiletries, there are more cases of expressing of function or effect of product through general image itself.
