In this paper, we present an ASIC(Application Specific Integrated Circuit) design of wavelet transform filter Wavelet transform is used in lots of application fields which include image compression, because it has an excellent energy compaction. The operation characteristic and performance of wavelet transform filter are analyzed by using verilog-HDL(Hardware Description Language). In this paper, the designed wavelet transform filter uses line memory to improve data processing rate. Generally, when it reads and writes data of DRAM by using Fast Page Mode, input and output processing is very fast in horizontal direction but substantially slow in vertical direction. The use of line memory solves this low speed processing problem. As a result, though the size of the chip is getting larger, processing time for an image frame becomes 4.66ms. Generally, since the limit of 1 frame processing time on the data of TV video is 33ms, so it is appropriate for TV video.

This study is reported the adhesion failure in adhesive bonded composite and specifically for the T-joint structure. Three-dimensional finite element analysis has been performed using a commercial tool and the necessary outcomes are obtained via an eight noded solid element (Solid 185-element) from the library of ANSYS. The structural analysis input has been incurred through ANSYS parametric design language (APDL) code. The normal and shear stress distributions along different layers of the joint structure have been evaluated as the final outcomes. Based on the stress distributions, failure location in the composite joint structure has been identified by using the Tsai-Wu stress failure criterion. It has been found that the failure index is maximum at the interface between flange and web part of the joint (top layer) which indicates the probable location of failure initiation. This kind of failures are considered as adhesion failure and the failure propagation is governed by strain energy release rate (SERR) of fracture mechanics. The different adhesion failure lengths are also considered at the failure location to calculate the SERR values i.e. mode I fracture (opening), mode II fracture (sliding) and mode III fracture (tearing) along the failure front. Also, virtual crack closure technique (VCCT) principle of fracture mechanics steps is used to calculate the above said SERRs. It is found that the mode I SERR is more dominating compared to other two modes of failure for the joint considered. Finally, the influences of various parametric (geometrical and material) effect on SERR of the joint structure are evaluated and discussed in details.

This paper proposes an expert system with the knowledge learning capability which can enhance the safety and effectiveness of substation operation in the automated substation as well as existing substation by inferring multiple events such as main transformer fault, busbar fault and main transformer work schedule under multiple inference mode and multiple objective mode and by considering totally the switch status and the main transformer operating constraints. Especially inference mode includes the local minimum tree search method and pattern recognition method to enhance the performance of real-time bus reconfiguration strategy. The inference engine of the expert system consists of intuitive inferencing part and logical inferencing part. The intuitive inferencing part offers the control strategy corresponding to the event which is most similar to the real event by searching based on a minimum distance classification method of pattern recognition methods. On the other hand, logical inferencing part makes real-time control strategy using real-time mode(best-first search method) when the intuitive inferencing is failed. Also, it builds up a knowledge base or appends a new knowledge to the knowledge base using pattern learning function. The expert system has main transformer fault, main transformer maintenance work and bus fault processing function. It is implemented as computer language, Visual C++ which has a dynamic programming function for implementing of inference engine and a MFC function for implementing of MMI. Finally, it's accuracy and effectiveness is proved by several event simulation works for a typical substation.

The purpose of this study was to describe how Korean nurses overcome the language barrier while working in the U.S. hospital settings. Twelve Korean nurses living in New York metropolitan area were asked open-ended, descriptive questions to collect the data. The interviews were done in Korean. All interviews were audiotaped under the permission of the participants and were transcribed verbatim. The data were analyzed using grounded theory analysis. The research process consisted of two phases. In the first phase 8 Korean nurses were interviewed and analyzed. In the second phase, further data were collected to verify categories and working hypotheses that were emerged from the first phase. The results of this study show that all Korean nurses experienced severe psychological stress such as confusion, anxiety, frustration, loss of self-confidence, embarrassment, guilt, depression, anger, and fear. Among the mode of communication such as listening, speaking, leading, and writing, they had the most difficulty in speaking. Speaking ability was especially important for them because of the emphasis of individualism and self-defense in the U.S. Among the verbal communication modes, non-face-to-face communications such as phone conversation and body language were the most difficu1t for them to overcome. It took at least 2 years for the participants to initially overcome the language barrier in U.S. hospitals. After 2-5 years they began to feel comfortable even in non-face-to-face communication. They could actively search for the better place to work after 5 years. They finally felt comfortable in English and in their job almost after 10 years. The factors that influenced the English improvement were ‘the years of clinical experience in Korea’, ‘the decade they came to the U.S.’ ‘coming to U.S. alone or with other Korean nurses’, ‘racial homogeneity or heterogeneity of the working unit’, and ‘the degree of social support’. The strategies Korean nurses used to overcome the language barrier included depending on the written communication, using ‘nunchi’, working and studying hard, and establishing good interpersonal relationships with co-workers. They also employed assertive behavior of the U.S., such as using more explicit verbal language and employing smiles and eye contact with others during the conversation. The results of the study may help Korean nurses and nursing students who try to work in U.S. hospital settings by understanding problems other Korean nurses faced, factors that influenced their English improvement, and strategies they used. They may also help U.S. nurses and administrators in developing and implementing efficient programs for newly employed Korean nurses by understanding major problems and feelings the Korean nurses experienced and strategies they used to overcome the language barriers.

In the history of the study of Shakespeare's texts the eighteenth century marked the emergence of editors, and in the history of Shakespearean editing Edmond Malone's emphasis on documentary evidence inaugurated a new stage. Malone's antiquarian scholarship sought to establish Shakespeare in the theatrical context of his age and a historically informed view of the physical circumstances under which he wrote his plays. Malone's editorial use of historical sources in terms of Shakespeare's past formulated a new mode of ascertaining his authorship: the construction of Shakespeare as a man of the theatre as well as of literature. Malone was the first scholar to recognize Shakespeare's merits as an actor, and to introduce the concept of the theatrical Shakespeare, which has become the scholarly norm since. In this respect this paper is designed to demonstrate that Malone's editorial principle and practice are characteristic of the identification of the factual documents of Shakespeare's biography, the authentication of his material to attain his true text, and the construction of his personal experiences through intensive readings of his plays. In conclusion, Malone's new criteria laid the foundation for the progress towards authorizing Shakespeare, thereby canonizing him as a figure of the theatrical and literary authority.

For Romantic women writers the paratext itself is essentially a masculine literary space affiliated with established writing practices; however, this paper suggests that Charlotte Turner Smith's mode of discourse in her use of notes and their relation to the text proper are never fixed in her contemplative blank-verse long poem, Beachy Head (1807). Even though the display of learning in the paratext partly supports the woman writer's claim to authority, this paper argues that Smith's endnotes also indicate her way of challenging the double bind for women writers, summoning masculine authority on the margins of her book while simultaneously interrogating essentialist thinking and instructions about one's identity in a culture and on the printed page. The poem shows how the fringes of the book can be effectively transformed from a masculine site of authority to an increasingly feminized site of interchange as Smith writes with an awareness of patriarchal, imperial abuses of power in that area of the book. There is a persistent transgression of cultural/textual boundaries occurring in Beachy Head, which explores the very scene and languages of imperial encounter. Accordingly, if Wordsworth's theory of composition suggests a subjective and abstract poetic experience-an experience without mediation-in which its medium's purpose seems to be to disappear from the reader's consciousness, an examination of the alternative discourse of self-exposure in Smith's poem reveals the essentially fluid nature of media-consciousness in the Romantic era, which remains little acknowledged in received accounts of Romantic literary culture.

This essay is an attempt to critique the notion of hybridity that has so far facilitated a liberal multiculturalist reading of White Teeth. For an alternative framework, it posits the multiethnic subject-making to examine in what ways the novel questions the premises of liberal multiculturalism. In this vein, this study suggests that Smith throws some significant light on the underside of holding multiple racial/ethnic identities while not bypassing its utopian possibilities. In case of the first-generation male characters, their crossracial/homosocial friendship becomes a platform for a mode of egalitarian belonging across the racial divide. It further implies a symbolic union between working-class white and nonwhite immigrant. The younger generation, in contrast, undergoes problems of racial, ethnic, cultural affiliations in far more complicated ways than the older one. Above all, White Teeth demonstrates the subtle workings of liberal multiculturalism, within which the younger characters are constructed to be a multiethnic subject in varied modes. It delineates the formation mainly by exploring the persisting legacies of Britain's imperial history that partake in their subject-making. The novel, in doing so, obliquely suggests that the younger generation is to confront the past that is a seminal part of their present life rather than have the freedom to throw it away to be a carefree member of a multicultural society.

The purpose of this study is to establish genre knowledge that can be used to study classical Korean novels. Genre knowledge is important because it characterizes individual works based on their knowledge, as well as organically links them with the social context. In this study, I suggest that long classical Korean novels with similar contents can be analyzed using genre knowledge and analyze the "register" of the representative work Sohyeonsungrok as an example of a classical Korean novel. In the Sydney school, register connects genre and language. Register comprises field, tenor, and mode in the social context, and ideological meaning, interpersonal meaning, and textual meaning through language. These three meanings help us to understand how experiences are transformed into language, the relationship between participants, and the way a text is organized. Based on these frameworks, this study reveals that the linguistic features of Sohyeonsungrok is "an attitude that accepts a wide range of human emotions and desires and steadily waits for it to be included in norms." Classic Korean novels such as Sohyeonsungrok depict characters who are not wicked even though they cannot fully comply with social norms, and thereby create sympathy for family members living through Confucian ideology. This genre knowledge is useful for understanding the ideological implications of classical Korean novels.
