In this paper, the degree-n bifurcation set as well as the Julia sets is defined by extending the concept of the Mandelbrot set to the complex polynomial $z^{n}{\;}+{\;}c(c{\;}\in{\;}C,{\;}n{\;}\geq{\;}2)$. Some properties of the degree-n bifurcation set and the Julia sets have been theoretically investigated including the symmetry, periodicity, boundedness, connectedness and the bifurcation points as well as the governing equation for the component centers. An efficient algorithm constructing both the degree-n bifurcation set and the Julia sets is proposed using theoretical results. The mouse-operated software calico "MANJUL" has been developed for the effective construction of the degree-n bifurcation set and the Julia sets in graphic environments with C++ programming language under the windows operating system. Simple mouse operations can construct and magnify the degree-n bifurcation set as well as the Julia sets. They not only compute the component period, bifurcation points and component centers but also save the images of the degree-n bifurcation set and the Julia sets to visually confirm various properties and the geometrical structure of the sets. A demonstration has verified the useful versatility of MANJUL.

고성능 해양모델을 개발하기 위하여 적시 컴파일(Just-In-Time) 언어인 줄리아 언어를 사용하였고, 운동량 방정식의 해를 구하기 위해 연속완화법으로 푸아송 방정식을 푸는 코드를 작성하였다. 다음으로, 줄리아 계산 코드를 시험하기 위하여 두 가지의 모델을 구축하였다. 첫 번째로, 일정한 유량의 생성/소멸(source/sink) 조건을 시험하기 위해 단순한 수로 형태를 모델링하였고, 두 번째로, 조석 외력(tidal forcing) 및 전향력(Coriolis force), 난류확산계수로 인한 효과 등을 시험하기 위해 황해(Yellow Sea)를 단순화하여 모델링하였다. 모델은 두 가지 시나리오 안에서 총 8개의 실험안으로 테스트되었다. 테스트 결과, 시나리오 1에서 3가지 실험안의 수심 평균된 유속은 이론 값에 완벽하게 수렴하였고, 해저마찰로 인한 수직적 유속 구배를 잘 보여주었다. 또한 시나리오 2에서는 황해의 무조점과 우리나라 서해 중부와 남부 연안의 조석 특성을 잘 재현하였고, 전향력과 수직 난류확산계수에 따른 결과의 차이를 잘 보여주었다. 따라서, 줄리아 언어를 이용한 해양모델을 개발하는 데에 성공하였다고 판단되며, 이는 해양모델이 고전적인 컴파일 언어에서 적시 컴파일 언어로 성공적으로 넘어가는 단계에 오게 됐다는 것을 시사한다.

This paper examines the meaning and significance of the rebirths narrated in Sylvia Plath's "Lady Lazarus." While the previous readings of the poem have regarded the speaker's rebirth as a single event, this paper aims to understand its plurality and the underlying problem of language and sound by listening to the poet's own reading of the poem. I argue first that the sound structure of the poem can be characterized by the poet's unique employment of vowel sounds. Drawing upon Plath's another poem entitled "Morning Song" and Julia Kristeva's concept of the chora, I contend that the poet's vowels signal her desire for regression to the pre-Oedipal space where sound and body are in direct contact without the interference of language. It is my conclusion that the rebirths in "Lady Lazarus" dramatize the poet's ongoing struggle to bypass the symbolic language in order to make her body heard.

Revisiting the horror of slave mutiny in nineteenth century America via Julia Kristeva's concept of abject, this essay examines abject fear in Amasa Delano and Babo's subversive act to deceive Delano in Herman Melville's "Benito Cereno." Babo, the slave, exercises subversive power, thereby reversing racial hierarchy aboard the slave ship-the San Dominick. Babo's ability to mimic and control racial stereotypes exposes how nineteenth-century racial hierarchy was only a social fiction, which becomes the very source of Delano's fear. Delano's dread belies upon the possible disruption of social order triggered by Babo'sblack rebellion. In order to repress his fear, Delano consciously and unconsciously attempts to re-inscribe white dominion and reaffirm black inferiority and stereotypes by means of rationalizing the disturbing signs he witnesses on the San Dominick. When Delano discovers the realsituation of the ship, he must relinquish the abject resonance that disturbs the previous racial order. Employing a legal document, Delano re-inscribes the official position of the blacks as slaves, defining them as violent savages, and thereby silences Babo. However, Melville's text is not a testament to white power. "Benito Cereno" actually endorses abject instability to challenge racial hierarchies through the poignant image of Babo's dead gaze in the last scene of the novella. Thus, "Benito Cereno" exemplifies the recurring power of abject as a threat to social hierarchy and as a constant reminder of the falsity and insecurity of a social order.

채팅로봇이란 인간과 기계가 서로 대화를 하는 컴퓨터 프로그램이다. 그 목표는 나와 대화를 하고 있는 상대방이 실제 인간인 것처럼 생각하도록 하는 것이다. 오늘날도 이 목표를 달성하기 위해 많은 연구자들이 노력하고 있으며, ELIZA, Julia, ALICE, 심심이 등 많은 채팅로봇이 개발되어 일반 사용자들에게 서비스를 제공하고 있다. 하지만 현재까지 개발된 많은 종류의 채팅로봇은 대부분 단순 패턴매칭 방식을 사용하고 있으며 이는 기존에 정의된 적절한 응답을 출력하는 것에 불과하다. 본 논문에서는 인터넷을 통해서 채팅할 때 사용하는 여러 형태의 통신어를 처리할 수 있는 방법을 제시하고 입력된 문장에 대해 형태소 분석과 품사부착을 통해 문장의 구조를 파악하고 분석된 구조를 토대로 모호한 문장의 패턴을 인식하여 인식률을 높이는 형태이다. 채팅로봇은 인터넷 업계에서 단순한 대화상대뿐만 아니라 특정 주제를 가진 홈페이지 또는 각종 쇼핑몰에서 다방면으로 그 활용도가 높기 때문에 성능이 높은 채팅로봇을 제작하여 사용한다면 사용자의 편의를 향상시키는 데에 큰 도움이 될 것으로 기대된다.

A critique on Freud's remembering taken place in the 80's and 90s has a significant impact on a paradigm shift: from the discursive constructivism to the neo-empiricism. Along with Marx and Nietzsche, Freud was one of the main intellectual sources in formulating the Cultural Studies, known as the political corrections in the later period of Post-modern era. In the wake of feminism, there was a social happening, namely, a memory restoration, when a woman therapist helped a woman patient to restore the past and come up with her father as the cause of her trauma. Finally, 'the false memory syndrome' brought up a hot issue firing on the controversy about Freudian remembering. Freud as a clinical therapist began to be a sole target to be criticized. Strangely enough, however, Freud was continually utilized by such theorists as Julia Kristeva, Homi Bhabah, and Žižek, while having dissenters like Deleuze, Quattari, and Butler. Of those intellectual claims, this paper focuses on the debates by the dissenters not from the discursive theorists but from the clinical studies: Sulloway, Grunbaum, and Crews. My argument directs to the empirical side of Freud for the conclusion that the dispute on him was a seed of a paradigm shift towards the neo-empiricism, after one century's flourishing of constructivism.

This study explores the concept of postmodernism in literature. There are many ideas which have conflicted with each other, but now postmodernism is real concept. We cannot deny. By researching papers of Jean-François Lyotard, Jean Baudrillard, Jacques Derrida, Michel Foucault, Julia Kristeva, Roland Barthes, Ihab Hassan etc. we find out many characteristics of postmodernism. From that, we propose a conceptual understanding of postmodern literature as follows: Starting from the late 1910s with the poetry of Dadaism (1916), Franz Kafka's prose (Metamorphosis 1915) and drama by Samuel Beckett (Waiting for Godot 1953), postmodern literature coexists with modern literature and is a thriving form from 1960 on. Postmodernism is opposed to modernism in nature in that it accepts nothingness, chaos, games and intertextuality. It tries to solve some difficult problems of modernism making use of science to free people from a life of darkness and dogma. Postmodernism is associated with the information technology revolution, an economic, scientific and technological boom and rapid urbanization.

The essay focuses on the relationship between the soldiers and the oppressed women in Lynn Nottage's Ruined (2009) in terms of Julia Kristeva's abject to show how the abjected Congolese women expose the falsehood of the order and identity that the military forces try to construct and maintain by war and violence. According to Kristeva, the abject is something that is rejected for the repulsion and horror it arouses but constantly draws the subject to it at the same time. Physically impaired and socially stigmatized, sexually abused Congolese women find a shelter in Mama Nadi's bar, the only place where they can continue their lives as the abject since the place, like the women themselves, lies outside the symbolic order occupied and corrupted by the men of DRC. Although the men involved in the armed conflict have abjected the women in pursuit of their own system and order, the women are not simply the objects of abuse and oppression. The men have to rely on Mama Nadi and her women not only to reaffirm their identity and power by suppressing them but also to fulfill their biological needs. In addition, the women's resistance against the soldiers demonstrates their power to challenge the men's symbolic order and expose its frailty. Apropos of the abject's resistance, various artistic genres such as poetry, music and dance appear in the play as an escape from the grim reality and a means of challenging and transcending the symbolic order. Bringing all these artistic elements together into a powerful piece of theatre-often considered as an 'abject' genre nowadays, Nottage demonstrates both the power of theatre as well as the tenacious Congolese women.
