Ikaino’s Afterlives: The Legacies of Landscape in the Fiction of Kim Yujeong
( Julia Hansell Clark ) 서울대학교 규장각한국학연구원 2023 Seoul journal of Korean studies Vol.36 No.1
This article examines the works of Kim Yujeong as a contemporary response to Ikaino literature, a subgenre of Zainichi Korean literature that flourished from the 1950s–1980s. Ikaino is the old name of the neighborhood of Osaka that was and remains the area of Japan with the largest population of Zainichi Koreans. Ikaino’s origins as a settlement of Korean migrant laborers in the 1920s and its official erasure from Osaka city maps in 1973 have often been mythologized within Zainichi Korean fiction and poetry. I read Kim Yujeong’s short stories “Tanpopo” (2000), “Murasame” (2002), and “Tamayura” (2015), which feature working women protagonists traversing Ikaino’s borders, as contemporary works of Ikaino literature that interrogate the Zainichi community’s cultural and historical understandings of the entangled geographies of Japan and the two Koreas. I argue that Kim portrays Ikaino landscapes as spaces constituted through their residents’ collective imaginings of Jeju Island and North Korea. Kim also subverts our expectations of multilingualism in Zainichi literature through the use of local dialect in her representation of Japanese residents of Ikaino. Throughout her work, she seeks to both shed light on the multiple structures of oppression that face Zainichi women living in the Ikaino area today, and critique the way those women have been represented in prior works of Zainichi literature.

Comprehensive measurements of atmospheric aerosols were made in Phimai, central Thailand (15.183<SUP>o</SUP>N, 102.565<SUP>o</SUP>E, elevation: 206 m) during the BASE-ASIA field experiment from late February to early May in 2006. The observed aerosol loading was sizable for this rural site (mean aerosol scattering: 108 +/- 64 Mm<SUP>-1</SUP>; absorption: 15 +/- 8 Mm<SUP>-1</SUP>; PM<SUB>10</SUB> concentration: 33 +/- 17 μg m<SUP>-3</SUP>), and dominated by submicron particles. Major aerosol compounds included carbonaceous (OC: 9.5 +/- 3.6 μg m<SUP>-3</SUP>; EC: 2.0 +/- 2.3 μg m<SUP>-3</SUP>) and secondary species (SO<SUB>4</SUB><SUP>2-</SUP>: 6.4 +/- 3.7 μg m<SUP>-3</SUP>, NH<SUB>4</SUB><SUP>+</SUP>: 2.2 +/- 1.3 μg m<SUP>-3</SUP>). While the site was seldom under the direct influence of large forest fires to its north, agricultural fires were ubiquitous during the experiment, as suggested by the substantial concentration of K<SUP>+</SUP> (0.56 +/- 0.33 μg m<SUP>-3</SUP>). Besides biomass burning, aerosols in Phimai during the experiment were also strongly influenced by industrial and vehicular emissions from the Bangkok metropolitan region and long-range transport from southern China. High humidity played an important role in determining the aerosol composition and properties in the region. Sulfate was primarily formed via aqueous phase reactions, and hygroscopic growth could enhance the aerosol light scattering by up to 60%, at the typical morning RH level of 85%. The aerosol single scattering albedo demonstrated distinct diurnal variation, ranging from 0.86 +/- 0.04 in the evening to 0.92 +/- 0.02 in the morning. This experiment marks the first time such comprehensive characterization of aerosols was made for rural central Thailand. Our results indicate that aerosol pollution has developed into a regional problem for northern Indochina, and may become more severe as the region's population and economy continue to grow.

<B>ABSTRACT</B><P>Cysteine proteinases are key virulence factors of the protozoan parasite <I>Entamoeba histolytica</I>. We have shown that cysteine proteinases play a central role in tissue invasion and disruption of host defenses by digesting components of the extracellular matrix, immunoglobulins, complement, and cytokines. Analysis of the <I>E. histolytica</I> genome project has revealed more than 40 genes encoding cysteine proteinases. We have focused on <I>E. histolytica</I> cysteine proteinase 1 (EhCP1) because it is one of two cysteine proteinases unique to invasive <I>E. histolytica</I> and is highly expressed and released. Recombinant EhCP1 was expressed in <I>Escherichia coli</I> and refolded to an active enzyme with a pH optimum of 6.0. We used positional-scanning synthetic tetrapeptide combinatorial libraries to map the specificity of the P1 to P4 subsites of the active site cleft. Arginine was strongly preferred at P2, an unusual specificity among clan CA proteinases. A new vinyl sulfone inhibitor, WRR483, was synthesized based on this specificity to target EhCP1. Recombinant EhCP1 cleaved key components of the host immune system, C3, immunoglobulin G, and pro-interleukin-18, in a time- and dose-dependent manner. EhCP1 localized to large cytoplasmic vesicles, distinct from the sites of other proteinases. To gain insight into the role of secreted cysteine proteinases in amebic invasion, we tested the effect of the vinyl sulfone cysteine proteinase inhibitors K11777 and WRR483 on invasion of human colonic xenografts. The resultant dramatic inhibition of invasion by both inhibitors in this human colonic model of amebiasis strongly suggests a significant role of secreted amebic proteinases, such as EhCP1, in the pathogenesis of amebiasis.</P>

In this paper, we present recent field studies conducted by NASA's SMART-COMMIT (and ACHIEVE, to be operated in 2013) mobile laboratories, jointly with distributed ground-based networks (e.g., AERONET, http://aeronet.gsfc.nasa.gov/ and MPLNET, http://mplnet.gsfc.nasa.gov/) and other contributing instruments over northern Southeast Asia. These three mobile laboratories, collectively called SMARTLabs (cf. http://smartlabs.gsfc.nasa.gov/, Surface-based Mobile Atmospheric Research &Testbed Laboratories) comprise a suite of surface remote sensing and in-situ instruments that are pivotal in providing high spectral and temporal measurements, complementing the collocated spatial observations from various Earth Observing System (EOS) satellites. A satellite-surface perspective and scientific findings, drawn from the BASE-ASIA (2006) field deployment as well as a series of ongoing 7-SEAS (2010-13) field activities over northern Southeast Asia are summarized, concerning (i) regional properties of aerosols from satellite and in-situ measurements, (ii) cloud properties from remote sensing and surface observations, (iii) vertical distribution of aerosols and clouds, and (iv) regional aerosol radiative effects and impact assessment. The aerosol burden over Southeast Asia in boreal spring, attributed to biomass burning, exhibits highly consistent spatial and temporal distribution patterns, with major variability arising from changes in the magnitude of the aerosol loading mediated by processes ranging from large-scale climate factors to diurnal meteorological events. Downwind from the source regions, the tightly coupled-aerosol-cloud system provides a unique, natural laboratory for further exploring the micro- and macro-scale relationships of the complex interactions. The climatic significance is presented through large-scale anti-correlations between aerosol and precipitation anomalies, showing spatial and seasonal variability, but their precise cause-and-effect relationships remain an open-ended question. To facilitate an improved understanding of the regional aerosol radiative effects, which continue to be one of the largest uncertainties in climate forcing, a joint international effort is required and anticipated to commence in springtime 2013 in northern Southeast Asia.

Using the techniques described above, we evaluated the effect of various exogenous factors on embryo development. The results of our previous experiments clearly demonstrated that carbohydrates (glucose, pyruvate and lactate), inorganic salts (NaCl and phosphate), amino acids, growth factors (PDGF, TGF, basic fibroblast growth factor, insulin and transferrin), antioxidants (mercaptoethanol and glutathione), arachidonic acid and cell-to-cell signal transducer (nitric oxide) affect bovine embryo development to the blastocyst stage. W e expect an increase in the number of transferrable blastocysts after modification of embryo culture system based on our experimental data.

The first measurement of the cross section for top-quark pair production in pp collisions at the Large Hadron Collider at center-of-mass energy s=7 TeV has been performed using a data sample corresponding to an integrated luminosity of 3.1+/-0.3 pb<SUP>-1</SUP> recorded by the CMS detector. This result utilizes the final state with two isolated, highly energetic charged leptons, large missing transverse energy, and two or more jets. Backgrounds from Drell-Yan and non-W/Z boson production are estimated from data. Eleven events are observed in the data with 2.1+/-1.0 events expected from background. The measured cross section is 194+/-72(stat.)+/-24(syst.)+/-21(lumi.) pb, consistent with next-to-leading order predictions.

A search for a heavy gauge boson W<SUP>'</SUP> has been conducted by the CMS experiment at the LHC in the decay channel with an electron and large transverse energy imbalance E<SUB>T</SUB><SUP>miss</SUP>, using proton-proton collision data corresponding to an integrated luminosity of 36 pb<SUP>-1</SUP>. No excess above standard model expectations is seen in the transverse mass distribution of the electron-E<SUB>T</SUB><SUP>miss</SUP> system. Assuming standard-model-like couplings and decay branching fractions, a W<SUP>'</SUP> boson with a mass less than 1.36 TeV/c<SUP>2</SUP> is excluded at 95% confidence level.
Search for supersymmetry in pp collisions at 7 TeV in events with jets and missing transverse energy
CMS Collaboration,Khachatryan, V.,Sirunyan, A.M.,Tumasyan, A.,Adam, W.,Bergauer, T.,Dragicevic, M.,Ero, J.,Fabjan, C.,Friedl, M.,Fruhwirth, R.,Ghete, V.M.,Hammer, J.,Hansel, S.,Hartl, C.,Hoch, M.,Horm North-Holland Pub. Co 2011 Physics letters: B Vol.698 No.3
A search for supersymmetry with R-parity conservation in proton-proton collisions at a centre-of-mass energy of 7 TeV is presented. The data correspond to an integrated luminosity of 35 pb<SUP>-1</SUP> collected by the CMS experiment at the LHC. The search is performed in events with jets and significant missing transverse energy, characteristic of the decays of heavy, pair-produced squarks and gluinos. The primary background, from standard model multijet production, is reduced by several orders of magnitude to a negligible level by the application of a set of robust kinematic requirements. With this selection, the data are consistent with the standard model backgrounds, namely tt@?, W+jet and Z+jet production, which are estimated from data control samples. Limits are set on the parameters of the constrained minimal supersymmetric extension of the standard model. These limits extend those set previously by experiments at the Tevatron and LEP colliders.
