        The genus Caenoscelis C. G. Thomson (Coleoptera: Cryptophagidae: Cryptophaginae) comprises approximately 30 species in the world, primarily distributed in the Holarctic region. Although 15 Caenoscelis species occur in the Palearctic region, only a single species, Caenoscelis sibirica Reitter, has been documented in Korea. In this study, Caenoscelis koreanus sp. nov. is described, and Caenoscelis ferruginea (C. R. Sahlberg) is reported for the first time in Korea. The new species can be distinguished from other Caenoscelis species by their subquadrate antennomere 10, fully developed hind wings, and male genitalia with subacute parameres and indistinctly separated lateral lobes. Illustrations of habitus, diagnostic characters, and a distribution map of Korean Caenoscelis species are provided.

        We investigate the diffusion process of Thomson-scattered line photons in both real space and frequency space through a Monte Carlo approach. The emission source is assumed to be monochromatic and point-like embedded at the center of a free electron region in the form of a sphere and a slab. In the case of a spherical region, the line profiles emergent at a location of Thomson optical depth τTh from the source exhibit the full width of the half maximum σλ ≃ τ 1.5 Th . In the slab case, we focus on the polarization behavior where the polarization direction flips from the normal direction of the slab to the parallel as the slab optical depth τTh increases from τTh ≪ 1 to τTh ≫ 1. We propose that the polarization flip to the parallel direction to the slab surface in optically thick slabs is attributed to the robustness of the Stokes parameter Q along the vertical axis with respect to the observer’s line of sight whereas randomization dominates the remaining region as τTh increases. A brief discussion on the importance of our study is presented.

        About 10 percent of quasars are known to exhibit deep broad absorption troughs blueward of prominent permitted emission lines, which are usually attributed to the existence of outflows slightly above he accretion disk around the supermassive black hole. Typical widths up to 0.2c of these absorption roughs indicate the velocity scales in which special relativistic effects may not be negligible. Under he assumption of the ubiquity of the broad absorption line region in quasars, the broad emission line flux will exhibit Thomson scattered components from these fast outflows. In this paper, we provide our Monte Carlo calculation of linear polarization of singly Thomson scattered line radiation with the careful considerations of special relativistic effects. The scattering region is approximated by a collection of rings that are moving outward with speeds υ =cβ < 0.2c near the equatorial plane, and the scattered line photons are collected according to its direction and wavelength in the observer's rest frame. We find that the significantly extended red tail appears in the scattered radiation. We also find that the linear degree of polarization of singly Thomson scattered line radiation is wavelength-dependent and hat there are significant differences in the linear degree of polarization from that computed from classical physics in the far red tail. We propose that the semi-forbidden broad emission line C III]1909 may be significantly contributed from Thomson scattering because this line has small resonance scattering optical depth in the broad absorption line region, which leads to distinct and significant polarized flux in this broad emission line.

        본 연구는 제임스 톰슨의 영향에 대한 엘리엇 자신의 진술을 출발점 으로 삼아, 엘리엇의 황무지와 톰슨의 무서운 밤의 도시를 상세하 게 비교하고, 런던에 대한 두 시인의 관심이 그들의 작품에 어떻게 나 타나며, 도시 풍경이 각각의 시에서 어떻게 구현되는지 살펴본다. 메마 른 도시의 배경에서 나온 두 작품 사이의 주제적 유사성, 즉 화자의 탐 색 모티프, 지옥 같은 도시의 현실, 비관적인 분위기 등은 쉽게 발견될 수 있다. 본고는 두 작품에 대한 세밀한 분석을 바탕으로 작가가 속한 시대적 차이와 무관하게, 황무지를 모더니스트 시로, 무서운 밤의 도시를 빅토리아조의 시로 만드는 요인의 유형을 논의한다. 황무지 의 구체적인 시각적 이미지와 음향의 현대성이 강조될 것이다. 특히 다 성어와 불협화음의 어구, 노래와 소음, 이질적인 다양한 목소리를 포함 하는 파편화된 소리의 차원이 충격적일 만큼 혁신적이고 독특하기 때문 이다.

        제임스 톰슨은 빅토리아 시대 시인으로서, 『두려운 밤』의 도시를 발표했는데, 『황무지』와 『두려운 밤』의 도시는 그 어조와 세계관 그리고 멜랑콜리적인 요소의 연관성으로 볼 때, 엘리엇은 톰슨의 작품을 염두에 두고 『황무지』를 집필한 것으로 추측된다. 실제 엘리엇이 강의했던 내용 중에 제임스 톰슨이 포함되어 있으며, 또한 엘리엇이 처음 톰슨을 읽었던 시기가 비교적 명확하게 기록되어 있는 것으로 미루어볼 때, 톰슨의 작품이 엘리엇의 문학세계를 형성하는데 중요한 바탕이 되었을 것 이다. 멜랑콜리적인 것으로 여겨지는 도상학적 이미지와 상징 그리고 전형적인 상실과 암울함 또는 희망과 구원에 대한 좌절 등이 두 작품에 공통적으로 나타나고 있는데, 『황무지』는 『두려운 밤의 도시』가 차용하고 있는 상당부분의 멜랑콜리적인 요소들을 반복하고 있다. 특히 작품의 중요한 인유로서 이용되고 있는 단테를 비롯하여, 다양한 중세회화의 도상들은 엘리엇의 『황무지』가 톰슨이 묘사하려고 했던 멜랑콜리적인 세계, 혹은 도시의 모습을 현대적으로 재현하고 있음을 보여준다.

        he main aim of this essay is to extract similarities between James Thomson’s The City of Dreadful Night of and The Waste Land. The names of the two poets have often been mentioned in connection, but the relation between their poetry has not drawn a serious attention. This essay is meant to track possible exchanges between the poets by examining mainly The City of Dreadful Night and The Waste Land. My focus has been on how Thomson influenced the urban scenes in Eliot’s poems and the images of the “Unreal City,” which are centered on London.Thomson’s poetry shows much influence from Dante. I have tried to present a meaningful number of verbal details showing that Eliot’s reading of Thomson was not confined to The City of Dreadful Night. Thomson seems to have also been a major influence on Eliot’s general thoughts and techniques. Eliot seems to make a good case of how a later-coming and greater-talented poet can make a more universally-appealing work out of the stuffs a locally-confined predecessor presented to the world.
