희생은 아일랜드 민족주의의 중요한 가치이자 독립 투쟁의 수단이기도 했다. 희생은 예이츠 초기희곡 세 작품—『캐슬린백작부인』,『캐슬린 니 훌리한』,『왕의 문지방』—의 주제이다. 이 논문은 이 세 작품을 중심으로 각기 다른 형태의 희생 을 연구한다.『캐슬린백작부인􋺸에서 캐슬린은 가난한 농부들을 구하기 위해 영혼까지 팔고, 『캐슬린 니 훌리한』에서 젊은 농부인 마이클은 아일랜드의 상징인 노파의 부름 에 응해 신부와 가족을 뒤에 두고 노파를 위해 싸우러 떠난다. 『왕의 문지방』에서 국 민시인인 샤나한은 국가평의회 위원이라는 시인의 오래된 권리를 수호하기 위해 목숨 을 희생한다. 이 논문의 목적은 주인공들의 희생의 의미와 그 희생에 대한 예이츠의 태도를 분석하는 것이다.

Nanostructured ZnO materials have been studied extensively because of their functional properties. This paper presents a composite material of zinc oxide quantum dots (ZnO QDs) and porous carbon using a one-step carbonization process. The direct carbonization of a metal–organic complex generates mesostructured porous carbon with a homogeneous distribution of ZnO QDs. The structural and morphological properties are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The resulting ZnO QDs@porous carbon composite delivers a high specific capacity of 990 mAh g−1 at 100 mA g−1, 357 mAh g−1 at 2 A g−1, and high reversibility when evaluated as an anode for lithium ion batteries.

용존 6가 우라늄은 다양한 화학종으로 존재하며, 화학종의 분포는 수용액의 pH에 의존한다. 산성 및 중성 근처의 pH 환경 에서는 대표적으로 UO2 2+, UO2OH+, (UO2)2(OH)2 2+, (UO2)3(OH)5 + 화학종이 공존한다. 수용액 속에 비결정성 실리카가 콜로이드 성질의 부유입자 상태로 존재할 때 용존 화학종은 실리카 표면에 쉽게 흡착된다. 이 연구에서는 표면 흡착 화학종의 분 포가 용존 화학종의 분포를 따르는지 조사하였다. 시료의 pH 값이 3.5-7.5인 조건에서 3종의 용존 화학종(UO2 2+, UO2OH+, (UO2)3(OH)5 +)과 2종의 표면 흡착 화학종(≡SiO2UO2, ≡SiO2(UO2)OH‐ 또는 ≡SiO2(UO2)3(OH)5 ‐)의 시간 분해 발광(luminescence) 스펙트럼을 측정하였다. pH 변화에 따른 각 화학종의 스펙트럼 변화 양상을 비교한 결과로 표면 흡착 U(VI) 화학종의 분포는 용존 U(VI) 화학종의 분포와 다르다는 것을 확인하였다.

Haemaphysalis longicornis (Hl) as members of the ixodid tick inhabits lots of grass thicket of field and mountain. Ticks are blood-feeding ectoparasites that can mediate a variety of diseases to human and animals, causing Lyme disease, Rocky Mountain spotted fever, and human monocytic ehrlichiosis. Particularly, ticks can trigger an inflammatory response representing symptoms about swelling and itching in human. The aim of this study is to investigate the effect of H. longicornis extract (HlE) on production of inflammatory cytokines and their mRNA in human monocytic THP-1 cells. In a time- and dose-dependent manner, human monocytic THP-1 cells was treated with HlE. Supernatants were analyzed for the production of cytokines using enzyme-linked immunosorbent assay (ELISA). mRNA level in the culture cells was measured by a reverse transcriptase-polymerase chain reaction (RT-PCR). As a result of this study, HlE significantly induced secretion of IL-6, IL-8, and MCP-1 in THP-1 cells. These results suggest that HlE increase the release of proteins and mRNAs level of inflammatory cytokines in THP-1 cells. HlE may play a role in contributing to inflammatory diseases through stimulation of immune cells. Further research of H. longicornis is needed to better understand the elucidation of the pathogenic mechanism.

Background : This study aimed to investigate the effect of elevated temperature by climate change on growth and ginsenoside contents of Korean ginseng, which requires low temperature during growth period. Methods and Results : Yunpoong was transplanted in temperature gradient chamber (TGC) for high temperature treatment and then growth characteristics and ginsenoside contents were investigated by growth period. Stem length, petiole length, leaf length and leaf width were increased as the temperature was higher than Ambient Temperature (Amb), but stalk diameter was decreased and small petiole length, number of petiole and leaf were no significant difference. Root growth, whereas, including length diameter and weight were decreased as the temperature was higher than Amb. Compared with Amb, root length, diameter and weight were decreased by 19.6%, 22.4% and 41.5% at Amb+6, respectively. The higher the temperatures are associated with the more ginsenoside contents. Compared to Amb, total ginsenoside contents were increased by 68% and 78% at Amb+4℃ and Amb+6℃, respectively. Almost all contents of individual ginsenoside, with the exception of Rg1, made a significant difference. Conclusion : When temperatures rises during growth period, the growth of ginseng was decreased but, ginsenoside contents were increased.

Background : The P. ginseng breeding line G07006, was selected for salt tolerance through salinity screening of mature leaves at the NIHHS of the RDA in 2014-2016. However, it is difficult to maintain a genetically stable breeding line of cross-pollinating crop in the field. Therefore molecular marker required to identify and maintain breeding line G07006. Methods and Results : DNA was extracted following the CTAB DNA extraction protocol (Doyle and Doyle, 1987) with modifications. A pair-end (PE) library was constructed and sequenced using an Illumina MiSeq platform by Lab Genomics, Inc. (Seongnam, Korea). Approximately 4.0 Gb of sequencing data were obtained, and de novo assembled by a CLC genome assembler(v. beta 4.6, CLC Inc., Rarhus, Denmark). The complete chloroplast(CP) genome size is 156,356 bp, including two inverted repeats (IRs) of 52,060 bp, separated by the large single-copy (LSC 86,174 bp) and small single-copy (SSC 18,122 bp) regions. This CP genome encodes 114 unigenes (80 protein-coding genes, four rRNA genes, and 30 tRNA genes), in which 18 are duplicated in the IR regions. Conclusion : This complete chloroplast DNA sequence will provide conducive to discriminate line G070006 (salt-tolerant) and further enhancing genetic improvement program of this important medical plant.
