In this study, a numerical scheme based on physical optics method is developed to predict RCS of perfectly conducting body. The scheme is verified through the comparisons of numerical values of cylinder and sphere with analytical ones. It is also applied to compute RCS of a fast naval craft. Major reflection of this ship at threat angle of 0 degrees is found to be due to superstructure and stern part of main hull. In order to investigate the shaping effects on the ship. inclination angles of the stern of main hull and superstructure are set to 12 degrees. The RCS of the ship with shaping is proven to be much reduced in comparison with one without shaping.

Piers are the main lateral force-resisting members of high-speed railway (HSR) bridges used in China and are characterized by low axial load ratios, low longitudinal reinforcement ratios, low stirrup ratios, and high shear span ratios. It is well known that flexural, flexural-shear, and shear failures of piers may occur during an earthquake. In this study, a new shear strength model was developed to simulate the seismic failure of HSR solid piers accurately. First, low cyclic-loading test data of solid piers obtained in recent years were collected to set up a database for model verification. Second, based on the test database, the applicability of existing shear strength models was evaluated. Finally, a new shear strength model for HSR solid piers with round-ended cross-sections was derived based on the truss model and ultimate equilibrium theory. In comparison with existing models, it was demonstrated that the proposed model could be used to predict the shear strength of HSR piers more accurately.

This study is aimed to investigate the aspect of using relative clauses in Korean. The data used for this study were extracted from the Korean text books for the foreign students and from the Chinese students' Korean compositions. They are the learners of Korean language at the early intermediated stage. As the result of analyzing them, the followings were found I)the majority of relative clauses in Korean consists of left-branching sentences. ii)The number of the subject relative clauses was higher than object ones in both of them. Especially in the aspect of using relative clauses, subject ones were used even more frequently than objective ones. This result is corresponded to the previous thesis, "the subject relative clauses was acquired earlier than object ones". iii)The relative clauses that those with a head noun function as subject in the main sentence showed in higher proportion in comparison of those as object. That is, this study showed that subjects were used more frequently than objects in the relative clauses used in their compositions. Finally, this study analyzed the errors of adnominal ending usage occurring in their compositions. More errors occurred when adjective form ended with '-hada' are changed into adnominal ending one.

"Duck Hunting" is the most psychological play with unique structure written by Aleksandr Vampilov. The play describes protagonist hero's furious behavior with psychological instability, therefore, this play tends to be recognized as serious and complicated one. After the death of Vampilov, "Duck Hunting" was reproduced as a film, titled as "Vacation in September." This study is designed to shed light on the play's psychological-dramatic factors by focusing on the structure of narrative and spatial-temporal objet. Also, this study compared the screenshots of the play with their textual meanings, then concentrated on main character's psychological features. By focusing on protagonist hero's mind, this study tries to look into the features of the play and its meanings for modern period. The film's plot is a kind of story telling structure based on main character's memory. The short stories of main character represents that Jilov(main character's name)'s losing his own life. The audience can acknowledge that Jilov's life as a duck hunter who is cynical, ideological, lazy, and self-interest oriented person. This play provokes the audience to compare their life to Jilov's one because such comparison helps the audience recognize their lives as surplus style of life with nihilism. Jilov as a character represents one of Soviet's generation with the feeling of great loss in 1960s.

The purpose of this paper look at the basis of the cultural differences of Korean and Japan by comparing the craftsmanship. Korean craftsmanship and master craftsman making traditional handcrafts and artwork would die out at a critical moment. The craftsmanship and system could not be established because of discrimination in the traditional four classes of society( scholars, farmers, artisans and tradesmen), invasions of other countries and discontinuity of tradition from modernization. On the contrast, in Japan, it was possible to establish traditional handcrafts and artworks, technique and craftsmanship with apprentice system and various social privilege and treatment even in the same traditional four classes of society ( scholars, farmers, artisans and tradesmen). It was common to pass down the family business for a hundreds of years with self respect between Japanese master craftsmen and lots of people succeed the family business will now. Japanese craftsmanship is originated from 'worship to god' Medieval Japanese believed that the thing changes human mind, artistic talent, masterpieces and faith were connected to sacred power. Therefore, master craftsmen and their works were also made by the power of god. In this context, craftsmen were protected and treated in socially and nationally. It is that the social treatments and supports in national level and their own pride and continuous training of techniques and abilities as the main driving force to maintain the craftsmanship in Japan. Korea has the sale level of competitive tradition and technique in comparison any other countries. Japanese craftsmanship study will be a critical data in the protection and maintenance of Korean traditional and technique.

In China, elder brother's wife is called 'Sao' or 'Saozi' and younger brother's wife is called 'Fu' or 'Difu', etc. On the other hand, In Korea is called 'Hyeongsu' and 'Jesu'. This paper aims to find that Korean and Chinese kinship terminology 'Hyeongsu' and 'Jesu's origin and characteristics. And considerd reason that Korean kinship terms different changed with Chineses and investigated whether the presence of native language. In China, Kinship term reflected strict species act. Therefore, for elder brother's wife to give dignity 'Sao' in the title that made separately. In other hand, sister-in-law used 'Fu that means submission. The first was to use the same type of Kinship terms in the Korean and Chinese. Because Korea accept of the China's relative terms. But gradually confusion about the meaning of the original issued 'Sao' and wrong term 'Jesu' appeared. In response, 'Hyeongsu' as a two-syllable terms was shown whence they came. Also through literature shows that '아??마', '아??마니 is called native tongue.

This paper is a study on The Korea Magzine. The magazine has a series. One of them is KOREA'S NOTED WOMEN. This is the women who are all Chinese women. They are Yo-WHA-SI(여와씨), A-WHANG, YU-YUNG(아황과 여영), T'AI-IM AND T'AI-SA(태임과 태사), WANG SO-KOON(왕소군), Su Wang Mo(서왕모), Yang Kwi-pi(양귀비), SU-SI(서시), TAK MOON-KOON(탁문군). The story of the women in the magazine were studied in a series of articles of reasons. First, it is because the Chinese women living in the hearts of Koreans. Second, the Koreans because these women want to love passionately, and be like. Third, because the Chinese women was also well-known in Korea as well known in East Asia. Was This series is used in any way. Features shown in the description was investigated. It explains how to understand what they Korea. Deliberately omitted, and were also added. I also used the analogy and comparison. This does not make sense but were accepted. Finally, we fully understand and take advantage of the literature.

The present paper deals with delamination fracture analyses of the multilayered functionally graded non-linear elastic Symmetric Split Beam (SSB) configurations. The material is functionally graded in both width and height directions in each layer. It is assumed that the material properties are distributed non-symmetrically with respect to the centroidal axes of the beam cross-section. Sine laws are used to describe the continuous variation of the material properties in the cross-sections of the layers. The delamination fracture is analyzed in terms of the strain energy release rate by considering the balance of the energy. A comparison with the J-integral is performed for verification. The solution derived is used for parametric analyses of the delamination fracture behavior of the multilayered functionally graded SSB in order to evaluate the effects of the sine gradients of the three material properties in the width and height directions of the layers and the location of the crack along the beam width on the strain energy release rate. The solution obtained is valid for two-dimensional functionally graded non-linear elastic SSB configurations which are made of an arbitrary number of lengthwise vertical layers. A delamination crack is located arbitrary between layers. Thus, the two crack arms have different widths. Besides, the layers have individual widths and material properties.

In their everyday life, people form social phenomena and relations through the shapes and habits of animals. Therefore, animals contain the idea of the way of life of certain nations, spiritual and cultural feelings, and the symbolic meaning which can be recognized between the members of the unique nation. The symbolism of animals varies depending on different nations, because the adages are the essence of the language including their culture, thought, custom, and life. Examining their own adages can be one of the ways to find out what the animals symbolize in different nations. Another reason is that they are the dictionaries, reflecting their own way of thinking and traditional values, so to speak. The research shows that, between Korean and Chinese adages, it is in a similar frequency, using materials such as mammals, birds, fishes, reptiles, and insects. The adages are focused on the 12 animals which is familiar to both nations, a rat, an ox, a tiger, a rabbit, a dragon, a snake, a horse, a lamb, a monkey, a rooster, a dog and a boar. We compared the symbolism, the surface meanings in adages, and the figurative meanings of these animals in Korea and China. As a result, it is found that some are almost the same in usage. However, some are totally different such as expressions related to the animals, the cultural differences and clear understanding. It is necessary to do comparative researches in a detailed and various way by studying the issues derived from verbalism.

At the turn of the century in which European colonialism was reaching its zenith and modernization was gathering speed, public museums were institutionalized. This paper looks into the part these European modern museums played in territorializing academic disciplines like anthropology and art history. The museums to deal with are the British Museum and the National Gallery in London, Mus?e du Louvre in Paris, and Museumsinsel in Berlin. Rather than in-depth detailed analysis of each museum, the aim is to explore the ways in which these museological institutions interacting with modern disciplines in the wider colonial context objectified other cultures and formulated a framework of the world through classification and comparison of material things, on the basis of the judgement of their artistic values. This exploration is also to rethink theoretical positions and perspectives on the museum in Korea. It is remarkable in Europe that such academic fields as history, art history, anthropology and cultural studies look for new possibilities of museology in conjunction with the recent proliferation of studies on the museum as a medium to construct and deconstruct knowledge. Meanwhile, the mammoth European museums which are often considered a stronghold of museology advocate the 'universal museum' themselves, quite the modern idea but in a revised rendering. Under these circumstances, this paper seeks to shed light on the definition of the museum as an arena in which scholarly discourses about art, culture and history can be created and contested, on the effectiveness of the museum as a communication medium in a postcolonial era, and on the need to pay trans-disciplinary attention to the museum in its broadest sense.
