In this paper, we address a new fast DCT-II/DFT/HWT hybrid transform architecture for digital video and fusion mobile handsets based on Jacket-like sparse matrix decomposition. This fast hybrid architecture is consist of source coding standard as MPEG-4, JPEG 2000 and digital filtering discrete Fourier transform, and has two operations: one is block-wise inverse Jacket matrix (BIJM) for DCT-II, and the other is element-wise inverse Jacket matrix (EIJM) for DFT/HWT. They have similar recursive computational fashion, which mean all of them can be decomposed to Kronecker products of an identity Hadamard matrix and a successively lower order sparse matrix. Based on this trait, we can develop a single chip of fast hybrid algorithm architecture for intelligent mobile handsets.

In this paper, I will explore disparate voices embedded in the interactions of stories in which personal, cultural, historical, and mythical consciousness brings up diverse ideas about the experiences of Native Americans. The accommodation of differences and changes is clearly manifested through the healing ceremony of Tayo, which poses some practical questions: what could be the authentic tradition of Native Americans?; which direction should it be led to? As these questions suggest, Tayo needs to think over and work through the way that Native oral stories will enrich the signification of being Indian within multicultural U. S. society. In other words, Tayo should transfer the oppositional relationship between Anglo and Native American world into an interactive one to bring forth new meanings concerning their interactions. As a hybrid, Tayo begins to recognize that his fragmented consciousness could represent the pervasive but surmountable anxiety about the cultural clash between Native and White Americans. Going through the multiple layers of his stories, Tayo learns that Native Americans need to hold a balanced viewpoint firmly: this demonstrates that storytelling brings restoration and renewal to him. As a result of Betonie's healing ceremony and his intimate relationship with Ts'eh, Tayo comes to have a holistic comprehension about how all the living things are interconnected to one another. After acquiring this recognition, Tayo succeeds in his quest to get back Josiah's cattle and recovers his identity as a Laguna Pueblo Indian, still letting diverse voices, cultures, and stories flow into the process of storytelling. As the last scene in which the conversations among Tayo, Auntie, and Grandmother took place illustrates, Tayo has newly secured a position that will require him to create a new, alternative story, not just repeating previous stories.

It is ironic but not coincidental that the loss of Korean sovereignty to Japan roughly paralleled the formation of the idea of Korean ethnic identity. The coalescence of the content of this heretofore amorphous notion of a "pure" and transcendental (in the class sense) ethnic essence was, again ironically, the result both of ideologies taken from (or given by) Japan and resistance to Japanese encroachment. What resulted was the birth of a hybrid (sub) consciousness that was able to accommodate disparate, or even contradictory, realities simultaneously without any sense of contradiction (Christian and shaman for example). If, as Kim Chul has asserted, the colonial period was the most impactful in forming today's Korean society and "giving birth" to today's Korean, it becomes easy to imagine how this formation process included elements of Japanese and western culture. This meant that there was going to be an inevitable cognitive dissonance when these influences collided with the imperatives of ethnic nationalism which became the touchstone for a common Korean identity (North and South). This paper attempts to show how this split-consciousness was manifested in Yeom Sang seop's Manse jeon with the aim of identifying how it affects discourses related to nationalism and identity.

Now a days, large volumes of data is accumulating in every field due to increase in capacity of storage devices. These large volumes of data can be applied with data mining for finding useful patterns which can be used for business growth, improving services, improving health conditions etc. Data from different sources can be combined before applying data mining. The data thus gathered can be misused for identity theft, fake credit/debit card transactions, etc. To overcome this, data mining techniques which provide privacy are required. There are several privacy preserving data mining techniques available in literature like randomization, perturbation, anonymization etc. This paper proposes an Enhanced Hybrid Privacy Preserving Data Mining(EHPPDM) technique. The proposed technique provides more privacy of data than existing techniques while providing better classification accuracy. The experimental results show that classification accuracies have increased using EHPPDM technique.

This paper examines the characteristics of post-modern self-portrait photography. Characteristics of postmodernism associated with the "loss of centeredness," such as the death of the author, interdisciplinarity, and intertextuality, brought about a number of changes within the self-portrait. The distinction between post-modern and modern self-portraiture can be characterized by the following qualities: appropriation, the use of photography, and the utilization of the human body as an art. The characteristics of post-modern self-portrait photography can be represented through the works of Cindy Sherman, Orlan, and Morimura Yasumasa. By presenting prototypical women in her works, Cindy Sherman not only represents images of those women, but also exposes her fictitious role in the work. She creates a distance between herself in the works and herself in reality and discloses a paternalistic gaze. Meanwhile, Orlan transforms her face into a distorted image and presents it as an alternative identity that is representative of postmodernism. She corrodes the standard concept of identity through plastic surgery and treats the face not as a place where the identity stays, but as a simple body part or fragment of skin. Orlan's post-human face is malleable according to the artist's desire to raise the issue of what the human face is, and opposes the structure of modernism. Morimura Yasumasa also appropriates images from masterpieces and presents a hybrid identity between Eastern and Western, male and female, original and replica, and subject and object. In order to dissect social prejudice, he puts forth every single structural dichotomy that coexists in his self-portrait and suppresses a strong ego. He also studies the relationship between 'seeing' and being 'seen' by trading the painter's role from that of the subject to that of the object.

영화감독 양영희의 두 편의 다큐멘터리 <디어 평양>(2005), <굿바이, 평양>(2009)과 극영화 <가족의 나라>(2013)는 재일코리안 디아스포라로서 감독의 자전적 경험을 바탕으로 제작된 영화로 남북한과 일본이라는 국민국가의 틈바구니에 선 재일코리안 디아스포라 문제를 제기하고 있다. 세 편의 영화는 제주, 오사카, 평양을 횡단하며 구축된 가족의 서사를 질문하는 것을 통해 국민국가가 부과한 경계를 의심하고 '가족의 나라'라는 새로운 탈주의 공간을 모색한다. 이 글은 양영희의 영화가 분단으로 한반도에 발생한 두 개의 국민국가가 강력하게 추구하는 통합과 일체감, 조국에 대한 획일적인 교육에 긴장을 일으키고 그것을 이질화시키면서 자신의 정체성을 재조정해가는 과정을 추적하였다. 결국 이들 영화는 국민국가의 경계를 넘나드는 혼종적 정체성에서 재일코리안 디아스포라의 미래 정체성을 예견하고 있는데 이는 동북아의 평화와 공존, 남북한의 적대성을 해체하는 작업에서 요구되는 타자 수용성, 개방성, 연대성의 가능성이 재일 코리안 디아스포라에게 있음을 보여주는 것이라 할 수 있다.

The purpose of this study is to examine various types and characteristics of masks and to consider what meanings they have in the recent fashion world. To this end, this study attempts to reflect on the internal meaning of masks exhibited in fashion designers' collections rather than functional meanings. It has an implication; in that it tries to help understand the expressive needs for variety and freshness pursued by modern fashion and use the unique design development to understand the internal meanings of masks. It, therefore, examines the existing domestic and foreign literature and data about masks from a theoretical perspective, and also attempts to draw findings from the data of fashion collections which have been held since the 2000s, as well as from literature research based on books about fashion and various other media. The meanings of masks in the field of fashion are as follows: First, they express identity, by criticizing the couture fashion, through the fashion. Second, they present a new concept of body, showing an illogical and ambiguous identity in which both feminine and masculine images coexist. Third, they are media externally communicating insights about human beings' inner world, through which various messages are transferred to modern people who are attached to external appearances, and the identities possessed by designers are revealed by the masks. Fourth, they ask about a boundary between gender and sexuality, as a means to make us concentrate on the important social issue, while expressing various and new identities, like the hybrid identity. In other words, they can be found to be used as effective media in communicating fashion massages intended by fashion experimental and creative designers.

줄종개(Cobitis tetralineata)와 왕종개(Iksookimia longicorpa)간 자연잡종으로 추정되는 개체를 유전적으로 동정하기 위하여 핵 recombination activating gene 1 (RAG1)과 미토콘드리아 cytochrome c oxidase I (COI) 유전자들의 염기서열을 분석하였다. RAG1 염기서열을 분석한 결과 850 bp 중에서 두 친어종들 간에 총 23개의 치환이 관찰되었고, 자연잡종 개체의 electropherogram에서는 이들 치환이 관찰된 모든 위치들에서 double peak들이 관찰되어, 멘델의 유전법칙을 따랐다. 그리고 모계를 통해 자손에게 유전되는 특징을 가지는 미토콘드리아 유전자들 중에서 COI 염기서열을 비교한 결과 잡종 개체는 줄종개와 염기서열이 100% 일치하여 그 모계는 줄종개임이 명확히 밝혀졌다.
