유한체 $GF(2^n)$에서 낮은 공간복잡도를 가지는 새로운 다중 분할 카라슈바 방법의 병렬 처리 곱셈기
장남수,한동국,정석원,김창한,Chang Nam-Su,Han Dong-Guk,Jung Seok-Won,Kim Chang Han 대한전자공학회 2004 電子工學會論文誌-SC (System and control) Vol.41 No.1
유한체 $GF(2^n)$에서 두 원소의 곱셈을 수행하는 공간 복잡도가 낮은 병렬 처리 곱셈기의 구현에 있어서 divide-and-conquer 방법은 유용하게 사용된다. 이를 이용한 가장 널리 알려진 알고리듬으로는 카라슈바 (Karatsuba-Ofman) 알고리듬과 다중 분할 카라슈바(Multi-Segment Karatsuba) 알고리듬이 있다. Leo ne은 카라슈바 알고리듬의 최적화된 반복 횟수를 제안하였고, Ernst는 다중 분할 카라슈바 방법을 이용한 일반적이고 확장 가능한 유한체 곱셈기를 제안하였다. 본 논문에서는 Ernst가 제시한 다중 분할 카라슈바 병렬 처리 곱셈기의 복잡도를 제시한다. 또한 기존 방법의 병렬 처리 곱셈기와 시간 복잡도는 같지만 공간 복잡도는 낮은 새로운 다중 분할 카라슈바 방법의 병렬 처리 곱셈기를 제안하며 그에 따른 최적화된 반복 횟수를 제안한다. 나아가서 제안하는 곱셈기가 몇몇 유한체에서 카라슈바 방법의 병렬 처리 곱셈기 보다 공간 복잡도에서 효과적임을 제시한다. The divide-and-conquer method is efficiently used in parallel multiplier over finite field $GF(2^n)$. Leone Proposed optimal stop condition for iteration of Karatsuba-Ofman algerian(KOA). Ernst et al. suggested Multi-Segment Karatsuba(MSK) method. In this paper, we analyze the complexity of a parallel MSK multiplier based on the method. We propose a new parallel MSK multiplier whose space complexity is same to each other. Additionally, we propose optimal stop condition for iteration of the new MSK method. In some finite fields, our proposed multiplier is more efficient than the KOA.

This paper aims to examine Dickens's Hard Times, on the assumption that its representation of the Benthamite Utilitarianism shows the disciplinary strategy of capital. Bentham's 'method of detail' turns out to be closely related to some essential characteristics of the capitalist economy ; the emphasis on the spirit of abstraction and calculation, the reduction of qualitative differences to quantitative differences, and so on. This alleged spirit of progress, contrary to its promise of the enlightened future, breeds not only uniformity and mechanical repetitiveness, but also misery and numbness in Coketown, locus of Hard Times. The strength of the Gradgrind-Bounderby regime is ultimately secured by the spread of 'normalized selves,' which are produced by the disciplinary operations of the complex of Utilitarianism and political economy. Their repression of curiosity and wonder inherent in children is a primary way of producing the fragile selves vulnerable to the dominating interests, opinions, and forces. However, there will be no future if we simply tread in the Utilitarians' disciplinary footsteps. Herein lies the importance of identifying and promoting the genuine self, i.e., Blake's 'identity'. Sissy, empowered with the strong individuality and creativity, vigor and energy, opposes the grounding principle of this regime and represents "another thing needful" to prevail over this inhumane spirit in Coketown. Dickens in Hard Times might be said to prefigure Foucault's notion of discipline. He doesn't just anticipate him, but goes further. Dickens, through Sissy, shows us the way out of the Foucauldian dilemma, which comprises astutely diagnosing the omnipotent and omnipresent power of disciplinary machinery without providing an alternative. It is this point in which Dickens's greatness as a creative writer lies.

In recent years, there has been an increased awareness of the effect of dietary constituents on the function of the central nervous system. Unlike previous beliefs, brain is found to be much more sensitive to normal daily fluctuations in nutrient supply. This paper will review neuronal roles of dietary precursor amino acids, tryptophan and histidine as they contribute to the formation of the neurotransmitters, serotonin and histamine. It will also discuss the role of vitamin B6 and its interaction with tryptophan or histidine in the neurotransmitter metabolism.

This paper aims to inquire the responsibility following the death of Jo in Bleak House. Jo and his 'habitat', Tom-all-Alone's are the critical links connecting the privileged and the under-privileged, the high and the low, so his death comes out to be central to the meaning of this novel, which is related with "class privilege and inequality" and also with the quality of life in this society. The recognition that, contrary to the apparent class distinctions, people cannot be ultimately separated and the so-called 'diseases' in one part of society soon contaminate the whole society comprises the main theme of this work, which is reinforced by the closely organized structure. The close relation of all the parts of this novel shows the writer's growing awareness of the social interconnections, and vice versa. If not, we don't have to pay attention to the social outcast like Jo. In order to establish connections between parts, Dickens resorts to, besides plot, many methods or motifs. We can enumerate the coherence of images, the mystery techniques, the motif of epidemic and parenthood, and "sudden relationships" among characters, and what not. In conclusion, it is clear the ultimate responsibility for the death of Jo should go to the whole social system, that is, the capitalist economy, not to the particular section. No one in this system is immune from the death of Jo.
