The purpose of this study was to analysis of the image of elementary school teachers on special class. The Q-methodology was used as a research method which is useful for analyzing subjectivity like as human value, attitude, belief and image. P-sample as subjects of this study was collected from 40 elementary school teacher in Busan. A data was analyzed using QUANL PC program. As a result of research, the image of elementary school teachers on special class was classified as 4 type. The 1 type was labeled the practical proponent type. The 1 type teachers highly estimate the educational importance of the special class and thought it as a place that educational possibility of children with disabilities can come true. The 2 type was labeled the passive bystander type. They are quite indifferent to the special class, and are skeptical about the educational achievement of children with disabilities. The 3 type was labeled the ideational positive type. They admit the importance of the special class, but thought that the image about the special class highly depends on the ability of the teachers who take responsibility for it. The 4 type was labeled the realistic opponent. They criticize the special class for not being the place that inclusion education for children with disabilities comes true and they are dissatisfied with the fact that ordered-curriculum for children with disabilities isn't applied at all.

To recognize F5-like (such as F5 and nsF5) steganographic algorithm from multi-class stego images, a recognition algorithm based on the identifiable statistical feature (IDSF) of F5-like steganography is proposed in this paper. First, this paper analyzes the special modification ways of F5-like steganography to image data, as well as the special changes of statistical properties of image data caused by the modifications. And then, by constructing appropriate feature extraction sources, the IDSF of F5-like steganography distinguished from others is extracted. Lastly, based on the extracted IDSFs and combined with the training of SVM (Support Vector Machine) classifier, a recognition algorithm is presented to recognize F5-like stego images from images set consisting of a large number of multi-class stego images. A series of experimental results based on the detection of five types of typical JPEG steganography (namely F5, nsF5, JSteg, Steghide and Outguess) indicate that, the proposed algorithm can distinguish F5-like stego images reliably from multi-class stego images generated by the steganography mentioned above. Furthermore, even if the types of some detected stego images are unknown, the proposed algorithm can still recognize F5-like stego images correctly with high accuracy.

By analyzing a national survey of public understanding of science and technology, this paper attempts to examine public perceptions of scientists and engineers in Korea. A special attention is given to the gap in the view of scientists and engineers across generation, gender, and class fields (or major fields). This paper shows that generation has the strongest effect on public perceptions of scientists and engineers among all the socio-demographic factors examined in this study. Those over 50 are more likely to have the conventional idealized images of scientists and the stereotypical negative images of scientists simultaneously, while the 20s are less likely to accept the idealized image of scientists. The survey result thus may suggest that the younger generation began to depart from a patriotic and moral description of scientists and engineers-for the younger generation, science and engineering is losing moral respect but becomes perceived as an ordinary occupation. Contrary to the popular belief, however, gender has little effect on public perceptions of scientists and engineers. This finding questions the assertion that female students possess more negative attitudes toward scientists and engineers than male students, and thus are reluctant to develop careers related to science and engineering. By uncovering that class fields (or major areas) have no effect on the image of scientists, this study also call into question the assertion in the science wars that the inadequate appreciation of science particularly among those who do not major in science and engineering is responsible for inadequate support for science and technology.

Department store has actively expanded cultural center services by providing a series of educational courses in order to increase customer visits, enhance customer satisfaction, and ultimately increase sales. In this study, cultural center members' shopping behaviors and image building of the department store were explored through focus group interviews. Results generated from a total of 7 focus group interviews with female cultural center members in their 30's through 60's are as follows. First, the consumer group who attends courses for their own purpose is 45 to 55 year-old female customers who are actively involved in consumption at the department store for their own clothing, food and restaurant. They are not often engaged in impulsive either group shopping for clothing. They are satisfied with class quality compared to low tuition whereas dissatisfied with busy schedule of a lecture room and lack of special discount benefits for members. Second, the other consumer group who attends courses for their children is consumers in their 30's. They are charged in shopping for clothing for their husbands, children, and themselves. They are suffering time poverty due to nurturing their children, therefore, they want to shop more in the department store on the day of class. However, expensive kids-care facilities are barriers to do it. Convenience, familiarity and center of culture are important images of the department store, developed through frequent visits of these customers. Eight implications for marketing strategies were generated based on study results.

The purpose of this study was to investigate how to develop of pre-service childcare teachers' perception about the image of childcare center teachers and self-image. In this study, participants' self-analysis method and in-depth interview were adopted to analyze the aspects of pre-service teachers' teacher image. Also, the narrative of pre-service teachers' a famous painting analysis were reported. The results of this study were divided into nine categories. Findings indicated that participants' self-image analysis work made pre-service teachers more enabled them to expend the significance of teacher's image of role in relation to their career decision and future their teacher's job. Moreover, through the experience of self-analysis work the pre-service teachers recognize their own ability to build up unique and healthy image. To foster the ability of pre-service teachers' self- image, special class teaching methods for pre-service teachers should be developed focusing on evoking them to have more positive self-image. This study suggested that self-image analysis work experiences should be emphasized in university class for pre-service teachers.

Scattering center extraction schemes for radar cross section reduction of large complex targets, like warships, was developed, which are an 1-D radar image method(range profile), and a direct analysis based on an object precision method. The analysis result of partial dihedral model shows that the presented direct analysis method is more efficient than the 1-D radar image method for scattering center extraction of interested targets, in terms of radar cross section reduction design, not signal processing. In order to verify the accuracy of the direct analysis method, a scattering center analysis of an naval weapon system was carried out, and the result was coincident with that of another well-known RCS analysis program. Finally, an analysis result of RCS and its scattering center of an 120m class warship-like model presented that the direct analysis method can be an efficient and powerful tools for radar cross section reduction of large complex targets.

Considering that star reflects the image of current society, analyzing fashion of celebrity is to read ideal type and demands of beauty of the era. Especially the rock music-represents youth culture that last on present day-born in 1960's, and it is considered to a significant decade in pop music history. Thus this research will analysis rock star's fashions in iconological view of E. Panofsky. The aim of this document is Clarifying how the fashion of pop stars appeared and what formed its worth. As a result of analyzing fashions of rock star in 1960's, it is available to find these sameness and difference. The Mods borrowed images of the past, and introduce the elite modernism and shows very urban style. The Folky and the Psychedelic showed post-structuralism propensity against industrial society, in the case of the Folky it induced styles that symbolize labor class to realize social worth. And as an aftereffect of war and repulsion of commercial worth, they embody nature-returning peasant look so that it shows pastoral mood in total. The Psychedelic express somewhat struggling escapism and it generated illusionary images with quests to superego and glorification to psychedelic status. The Folky and the Psychedelic are same in the side of introducing existentialism, this occurred by using ethnic factor. But the Folky showed plain outlook by pop propensity, on the other hand, the Psychedelic showed magnificent outlook such as optical art, pop art, and futurism ought to express merrymaking culture. And common feature of these is introduction of unisex mod which is came after the change of gender role. Thus each star or group has professed special ideology into their culture and it is reflected to acts which is including music and dress style. This affair is analyzed like these two things. The mass of people schemes their identity with inducing special ideology to their culture at the first. And the purpose to archive cultural hegemony in inter-social class at the next.

This paper is the second part of a series of the research about the Teddy boy style which is to examine various fashion changes in subcultural styles in 1900s. The main concern of this research is to investigate the creation and meaning of the Teddy boy style, how it interacted with the elements of class and generation and how the materials needed by the group constructed and appropriated into the visible systematic cultural form of correspondence. The Teddy Boys are the first recognized members of the British youth culture, which is known as the new Edwardian because of their dress. They had created the concept of the "teenagers," which forms the basis of the sense of a "generation" in the 20th century. The Teds set the style that would be used and modified in the following generations. They adopted the Edwardian style of the upper class, and changed it into their own style by modifying it and adding to it some other elements. The Teddy boys style is a special version of the sartorial appropriation encountered in the sphere of the fashion history. It actually began immediately after the war by the upper class youth far from the working class neighborhood. In the late 1953, the elitist aura surrounding the Edwardian suit was suddenly shattered. Within just a few months, the Edwardian suit became a source of social anxiety and the focus of a symbolic battle. Although the Edwardian look had initially went back to the upper class root, it became a symbol of rootlessness. In appropriation of this image, The Teddy boys were also rejecting the sartorial conformism of the English working class with its modest tradition. In this respect, the Teds effected the ascent or fall of the working class in the area of fashion. The Teds dress was not a merely borrowed fashion, but was a bastard fashion in the form of American trends, the Zoot suit. At this time members of the working class possessed only work dress for the week and waist suits for the Sunday outings. Teds broke this pattern, and developed the working class dandyism of wearing clothes simply to show off. The results were that they succeeded in opening the teen market, and popularizing a working class style for the first time in British history. The Teds became the first British street style with ties music, and remain as an symbol of the rising of a new age of values and styles.f values and styles.

Jacket matrices, motivated by the complex Hadamard matrix, have played important roles in signal processing, communications, image compression, cryptography, etc. In this paper, we suggest a novel approach to design a simple class of space-time block codes (STBCs) to reduce its peak-to-average power ratio. The proposed code provides coding gain due to the characteristics of the complex Hadamard matrix, which is a special case of Jacket matrices. Also, it can achieve full rate and full diversity with the simple decoding. Simulations show the good performance of the proposed codes in terms of symbol error rate. For generality, a kind of quasi-orthogonal STBC may be similarly designed with the improved performance.

Colour consistency is an important consideration when selecting pigments used on works of art. In this study, we analyse the colour difference between two sets of synthetic blue glass pigments acquired at least 8 years apart from the same manufacturer in Japan. The old pigment set (unused, dry powder with four different grain sizes) appears faded compared to the new set. These pigments are made available for artistic use, commonly in Nihonga or Japanese paintings. Raman spectroscopy and SEM-EDS results characterize these pigments as cobalt aluminate spinels dissolved in leaded glaze, a special class of complex coloured inorganic pigments that is not well-understood in the field of conservation. Colour difference between the old and new pigments with four different grain sizes were quantified by analysing photomicrographs with image analysis software. Blue pigments with coarse and extremely fine grains showed significant colour change compared to pigments with medium and fine grain sizes. The high occurrence of crystallites in the finer grains give a final colour that is bluer and lighter. Possible causes for the colour difference including manufacturing methods and storage environment are discussed.
