Objective: Present investigation was aimed to study the Single Nucleotide Variants of the luteinizing hormone beta ($LH{\beta}$) gene and to analyze their association with the semen quality (fresh and post-thawed frozen semen) and luteinizing hormone (LH) concentrations in Murrah buffalo bulls. Methods: Polymerase chain reaction-single stranded conformational polymorphism (PCR-SSCP) and Sanger sequencing method is used to study genetic variability in $LH{\beta}$ gene. LH assay was carried out using enzyme-linked immunosorbent assay method. A fixed general linear model was used to analyze association of single nucleotide polymorphism (SNP) of $LH{\beta}$ gene with semen quality in 109 and LH concentrations in 80 Murrah bulls. Results: $LH{\beta}$ gene was found to be polymorphic. Total six SNPs were identified in $LH{\beta}$ gene g C356090A, g C356113T, g A356701G, g G355869A, g G356330C, and g G356606T. Single Stranded Conformational Polymorphism variants of pattern 2 of exon 1+pattern 2 of exon 2+pattern 1 of exon 3 had highly significant (p<0.01) effect on sperm concentration (million/mL), percent mass motility, acrosome integrity and membrane integrity in fresh and frozen semen whereas significant (p<0.05) effect was observed on percent live spermatozoa. SSCP variants of pattern 2 of exon 1+pattern 2 of exon 2+pattern 1 of exon 3 had highly significant (p<0.01) effect on luteinizing hormone concentrations too. Conclusion: The observed association between SSCP variants of $LH{\beta}$ gene with semen quality parameters and LH concentrations indicated the possibilities of using $LH{\beta}$ as a candidate gene for identification of markers for semen quality traits and LH concentrations in Murrah buffaloes.

Byron’s Cannibalistic Imagination and the End of War

Suh-Reen Han 19세기영어권문학회 2016 19세기 영어권 문학 Vol.20 No.1

The aim of this essay is to revisit Derrida’s notion of the carnivorous subject and the question of eating well through the trope of cannibalism in Byron’s Don Juan. Cannibalism is an extreme form of flesh eating, which exposes for Byron the voracious underbelly of an economic and political system that feeds on the human flesh. Evidently, the most atrocious manifestation of such rapacious appetite for the human flesh is war, and the urgency with which Byron condemns carnage in military conflicts underlies his recourse to the radical carnivoracity of cannibalism. With the aid of Kant’s own allusion to cannibalism in his treatise on war and perpetual peace, I will offer a new perspective on the possibility of Kantian hospitality as imagined in Don Juan. Many critics have written on the question of appetite in Byron’s works, but most remain limited to the sphere of cultural and anthropological criticism. Discussions of Byron’s critique of war and politics, on the other hand, have inadequately addressed the moral imperative that is implicit in his anti-war sentiment. Exploring cannibalism as the limit experience of “eating badly” and treating others as a means rather than an end, I propose to read Byron’s figure of the cannibalistic appetite as a profoundly moral critique of modern culture’s unrelenting demand for the sacrifice of the human flesh.

Chemical and biological agents were evaluated to in- hibit Colletotrichum fructicola, Phytophthora cactorum, and Lasiodiplodia theobromae causing strawberry dis- eases. Mycelial growths of C. fructicola were gradually arrested by increasing concentrations of fungicides pyraclostrobin and iminoctadine tris (albesilate). P. cac- torum and L. theobromae were more sensitive to pyra- clostrobin compared to C. fructicola, but iminoctadine tris (albesilate) was not or less effective to limit P. cac- torum or L. theobromae, respectively. Bacillus siamensis H30-3 was antagonistic against the three pathogens by diffusible as well as volatile molecules, and evidently reduced aerial mycelial formation of P. cactorum. B. siamensis H30-3 growth was declined by at least 0.025 mg/ml of pyraclostrobin. The two fungicides additively inhibited mycelial growths of C. fructicola, but not of P. cactorum and L. theobromae. B. siamensis H30-3 vola- tiles led to less growth of C. fructicola than one reduced by the fungicides. Taken together, in vitro antimicrobial activities of the two fungicides together with or without B. siamensis H30-3 volatiles may be cautiously incorpo- rated into integrated management of strawberry dis- eases dependent on causal pathogens.

The Aesthete as the Modern Man

Suh-Reen Han 19세기영어권문학회 2010 19세기 영어권 문학 Vol.14 No.1

Reading Oscar Wilde’s The Picture of Dorian Gray as a novel that performs Foucault’s idea of discursive formation, this essay explores various formal aspects of discursive formation as figured by the novel’s statements, most notably the highly stylized epigrams. Words in the novel, I argue, operate at the level of the surface, converging from different disciplines to give shape to Dorian Gray, who with his two faces emerges as a de-subjectified “type” of the new discourse of Hedonism. At the site of such occurrence, we come to recognize a new form of knowledge appearing between the apparent “faces” of the novel: an unarticulated but already understood epistemology of homosexuality whose silence gives form to the inherent paradox between expression and repression?the “already-said” and the “never-said”?in discourse. Wilde’s novel presents homosexuality as a residual, yet potentially subversive, form of knowledge emerging from the fissures between contending ideas of art and morality. Dorian’s mysterious absence hiding unspeakable acts of perversion and his prominent presence as the new artist type both work to epitomize this dynamic process of discursive formation. With new aestheticism forming the other side of homoeroticism, Wilde’s novel thus stages the generation and representation of power through a network of words and tactics that construct discourse?i.e., Foucauldian power which resides in the knowledge produced by discursive practices. As this essay concludes, The Picture of Dorian Gray does not just refer to art as the figure for discourse with its innately subversive power; it also performs power through the particular form of art that is the novel. The self-reflexivity of the novel allows us to read it as a narrative about discursive formation and to experience it as a singular event in which a new discourse of art and life occurs to turn the course of history.

Surviving the Revolution: Wordsworth`s Spots of Time, Trauma, and History

( Suh Reen Han ) 한국영어영문학회 2013 영어 영문학 Vol.59 No.6

This essay argues that Wordsworth`s spots of time in The Prelude have a deeper connection with his sense of history than has commonly been perceived by critics. Deviating from the viewpoint that the spots of time signal Wordsworth`s turn from historical to poetical interest, this essay observes that the spots of time recur across the boundary between history and poetry. A close look at the figure of the "spot" in Books 9 and 10 of The Prelude (1805) reveal that it marks the punctual points in the poet`s encounter with history where the individual mind suffers a sense of severe discordance with the world. Often that sense originates from the inability to comprehend the magnitude of the French Revolution and its violence. Freud``s analysis of war neurosis helps to unveil the traumatic nature of Wordsworth`s revolutionary experiences, the shock of which is repeated and intensified with each spot that marks the revolution`s monumental impact on the poet`s mind and feeling. A sense of history as the irrational repetition of fear emerges with each repetition of the spot, offering the most profound critique of a revolution forever seized in that punctual juncture of historical rupture. Wordsworth`s encounter with history leaves behind a certain pattern of the mind and residue of feeling that determine the spots of time after the revolution, giving him a way to put into poetic figure the enigma of human nature and the natural world. Thus, Wordsworth`s poetic form rises out of the traumatic experience of having lived and survived the revolution.

Kant and Coleridge : Addictions of the Modern Self

Suh-Reen Han 19세기영어권문학회 2013 19세기 영어권 문학 Vol.17 No.2

This essay explores the question of the body and addiction raised by Immanuel Kant and Samuel Taylor Coleridge as they fashion themselves into modern subjects. While studies of the philosophical connection between Kant and Coleridge have well been established, the somewhat counterintuitive relationship between the health-mongering Kant and the opium addict Coleridge has not drawn enough critical attention. Looking closely at the ways in which Kant and Coleridge attend to their bodies, this essay argues that both forms of obsession over the body ? whether as a health nut or as a junkie ? share the problem of dealing with the high pressures of being a modern subject. Modern subjectivity is first and foremost grounded on the idea of autonomy : the free and rational “I”. The idea of autonomy puts an emphasis on the independence and self-sufficiency of the modern self. The Enlightenment imperative is that the subject ought to be an individual in full possession of his or her self ; concepts born from this demand ? right, reason, imagination ? are predicated on the individual as the basic form of subjectivity. Kant’s compulsive dependence on a self-devised physical regimen to prolong life and maintain mental health is a symptomatic sign of how demanding this imperative can be. Coleridge’s opium addiction, on the hand, sheds light on the possibilities and limitations of the Romantic poet’s identity as an original author. A careful analysis of the bodily addictions of these two figures offers an intriguing way of tracing the connections and tensions between Enlightenment and Romanticism at the birth of the modern subject.

Byron’s Queer Lyric: “To Thyrza”

( Suh-reen Han ) 한국영미문학페미니즘학회 2018 영미문학페미니즘 Vol.26 No.3

This essay is a study of a particularly “queer” moment in Byron’s lyric poetry. In “To Thyrza,” a short poem Byron wrote in response to the death of John Edleston, a choirboy Byron fell in love with at Cambridge, the speaker struggles through an exceedingly convoluted and ambiguous passage to express his excruciating pain. In answer to this perplexing poem, this essay proposes a study of the correlation between queer desire and the lyric form in Byron’s poetry. The lyric is not a poetic form usually associated with Byron, and yet in “To Thyrza,” we find a poet who relies on the lyric voice to express what is the most private and dearest to his heart. Queer desire has always been a slippery slope for those who question the possibility of a proper language for desire, and poststructuralist theories of sexuality have looked to language as a site of displacement and substitution for illicit desire. This essay’s reflection on queer lyric is an intervention into this poststructuralist perspective. Lyric poetry is a peculiar fusion of voice and text, and the intrinsic tension between these two linguistic impulses in the lyric has us wonder what the lyric voice can do beyond and against textual displacements of desire. When the lyric voice makes itself heard somewhere outside the structure of the text, it makes space for the voice of displaced desire to reverberate as in an echo box. Queer lyric resides in that space, and this essay’s reading of Byron’s “To Thyrza” contemplates the radical possibility of such a queer lyric.

Creaturely Right in Mary Shelley’s Frankenstein

( Suh-reen Han ) 영미문학연구회 2020 영미문학연구 Vol.38 No.-

This essay raises the question of creaturely right and its cosmopolitan possibilities in Mary Shelley’s Frankenstein by arguing that the novel’s awareness toward the creaturely condition of earthly life allows us to imagine universal hospitality in the most radical sense. Exploring how the novel identifies the creature as the bearer of life and the creator as the sovereign, this essay’s reading opens another way to discuss the question of power and life beyond Foucauldian and Agambenian perspectives on biopolitics. Noting that the Judeo-Christian strain of imagining life given to creatures by the sovereign creator of life has been strangely neglected in current biopolitical discourse, the purpose of this essay is to demonstrate that the notion of creaturely life still persists in Western epistemology at the center of Enlightenment’s secularizing efforts. More importantly, the question of creaturely life and the creator’s sovereign power complicates modern biopolitics, opening another way to locate the epistemological grounds for violence toward life. This essay’s exploration of the creature’s right of life in Frankenstein will hopefully contribute to expanding our dialogue on power and life.
