Hipp8ie style was introduced in 1960s when young generation's movement against industrial society and mass culture was spread. Its value was to go back to "Real and Pure Nature". Hippie originated from "Human Be-in" which was on-violent revolution held in sanfrancisco. American Hippie style was represented through freedom and love based on drug and psychedelic culture which were created by the young generation who were against traditional esthetic value as well as the moral and material value. However, Hippie style was represented differently in France. The privilege classes such as artists who were interested in surrealism, art negro and primitive culture, the intelligentsia like Montparnass in Paris, accepted Hippie style faster than ordinary people did. therefor, Hippie style in france was represented as an esthetic mode not a symbol of anti-culture and anti-policy. The general public imitated the style of the privileged classes and coordinated their style according to their personality without any standard such as blue jeans, ethnic, psychedelic, mini, mods, beatnik, etc. Yves Saint Laurent who was influenced by hippies led the mode of Paris to introduce "Africa", "Saharienne", "Pathwork". therefore, in 1960's fashion in Paris, everything was possible because of too many changes in fashion and refusal of accepting vogue.

The stochastic properties of variation in fatigue crack growth are important in reliability and stability of structures. In this study,the stochastic model for the variation of fatigue crack growth rate was proposed in consideration of nonhomogeneity of materials. For this model, experiments were ocnducted on 7075-T6 aluminum alloy under the constant stress intensity factor range. The variation of fatigue crack growth rate was expressed by random variables Z and r based on the variation of material coefficients C and m in the paris-Erodogan's equation. The distribution of fatigue life with respect to the stress intensity factor range was evaluated by the stochastic Markov chain model based on the Paris-Erdogan's equation. The merit of proposed model is that only a small number of test are required to determine this this function, and fatigue crack growth life is easily predicted at the given stress intensity factor range.

This paper presents the physical formulation of a 1D material model suitable for seismic applications. It is written within the framework of thermodynamics with internal variables that is, especially, very efficient for the phenomenological representation of material behaviors at macroscale: those of the representative elementary volume. The model can reproduce the main characteristics observed for concrete, that is nonsymetric loading rate-dependent (viscoelasticity) behavior with appearance of permanent deformations and local hysteresis (continuum plasticity), stiffness degradation (continuum damage), cracking due to displacement localization (discrete plasticity or damage). The parameters have a clear physical meaning and can thus be easily identified. Although this point is not detailed in the paper, this material model is developed to be implemented in a finite element computer program. Therefore, for the benefit of the robustness of the numerical implementation, (i) linear state equations (no local iteration required) are defined whenever possible and (ii) the conditions in which the presented model can enter the generalized standard materials class - whose elements benefit from good global and local stability properties - are clearly established. To illustrate the capabilities of this model - among them for Earthquake Engineering applications - results of some numerical applications are presented.

The existence of Korean schools is one of the salient characteristics of Overseas Koreans. How do such schools for Korean immigrants' children try to construct Korean ethnic identity? Also, how is immigrant children's ethnic identity developed and reinforced by the education at those schools? This paper explores these questions based on an ethnographic research at a Korean school in Paris from September 2005 to December 2007. The cultural education for immigrant children at the Korean school has a tendency to emphasize the most exotic traits of Korean culture. And this emphasis on the unfamiliar elements of Korean culture doesn't seem to help to form the ethnic identity of Korean immigrants' children. Instead, the students appear to get the sense of being a member of Koreans more from the education outside of classroom such as scholastic events than in a classroom of a Korean school. That's because scholastic events allow them to play out some of the Korean culture in more inter-ethnic settings. Therefore, it can be concluded that ethnicity of immigrant children is rather developed in inter-ethnic social contexts than born with or taught in class.

This study was aimed to analyze and investigate a diversity of aesthetic values expressed in the military look designs of the Paris collections by using content analysis method to find what design characteristic and image emerged in the later 20th century. A total of 267 military look works shown in fashion magazines such as Vogue and Collezioni Donna over the period between 1996 and 2000 were collected as research data, which were classified into 5 categories such as item, silhouette, color, color coordination, fashion image. The results were summarized as follows: first, it was found that coat was the most preferred item in expressing the military look image. Second, the straight line was the most referred silhouette, which indicates that it was the most suitable silhouette in expressing he bisexual image of the military look. Third, achromatic colors such as black and white were found to be of the highest frequency, which shows that achromatic colors continued to be proposed as fashionable colors around 1996 and this influence was effected in the military look. Finally, monochromatic coordination accounted for more than half of the military look, through which it could be explained that designers utilized it greatly to make an effective expression of the masculine image.

The purpose of this is to investigate the color of Art Deco Fashion in Paris. (1920-1930) Through the age of Art Deco style, the enormous modern cities were built up and numerous life-constructions were designed conspiciously in Paris. Under this situation, the usage of the 'color' became very important element of design area and also it bestowed new form upon the modern design. The black beauty of Art Deco style was the outcomes of cubism, black-arts, and pragmatism. And the black beauty was regarded as the proper color to represent simplicity. Simplicity was the best way to express Art Deco style. The color and light of metal were used adequately to express a geometrical and streamline form; it was raised as a new beauty in this period. The primary colors were used to recognize the simplified forms effectively. New pastel colors, which signified differently with Art Nouveau were born centering around the Youth Culture like a summer resort and a sun bath. Also they expressed neon signs and atmosphere of beach by means of the tropical colors. At last the color of Art Deco style opened the new age. And it was started to use the various colors in design field from at this time.

It is important to calculate the exact crack opening area in the cracked pipe subjected to axial force and bending moment. Among many solutions for obtaining the crack opening displacement, Paris-Tada's expression, which is derived from energy method, is open used in fracture analysis for piping crack problems because of its simplicity. But Paris-Tada's equation has conservativeness when radius over thickness ratio(R/t) is ten or less, for it is based on the stress intensity factor solution having a compliance function derived from a simple shell theory. In this paper we derived a new expression using a different stress intensity factor solution which is able to consider the variation of compliance through wall thickness in a cracked pipe. Conservativeness of both equations was examined and compared to finite element analysis results. Conservativeness of the new equation is decreased when R/t > 10 and increased slightly when R/t < 10 compared with Paris-Tada's. But Both equations were highly conservative when R/t < 10 compared with finite element analysis results.
