박소영,오예은,왕흔신,홍수민 한국물류학회 2024 물류학회지 Vol.34 No.2

본 연구는 선박 저속운항과 대체 연료 추진선 도입이 선박의 CO2 배출량 감축에 미치는 영향에 대해 분석하기 위해 시스템 다이내믹스(System Dynamics)를 활용하였다. 2022년 컨테이너 선박의 연료소모량 및 운항 데이터를 기반으로 선박 저속운항 관련 1 개 시나리오와 대체 연료 사용에 대한 12개 시나리오를 설정하여 10년간 CO2 배출량 및 연료 비용을 산정하였다. 분석 결과, 저속운항에 따른 CO2 배출량 및 연료비용 저감 효과는 미미한 것으로 나타났다. 반면, 기존 연료인 LFO와 HFO를 LNG로 대체하는 경우 CO2 배출량 감축 효과는 큰 것으로 나타났으나 연료 비용 또한 증가하는 것으로 나타났다. 프로판 가스의 경우 LNG에 비해연료 비용과 CO2 감축 효과 모두 낮은 것으로 확인되었다. 단기적 관점에서 저속운항이 배출량 감소에 효과적이지만 저속운항에따른 운항 시간 증가와 비용이 증가할 가능성이 있다. 따라서 장기적 관점에서 대체 연료 추진선 도입을 추진해야 하지만 대체연료 수급 불안정성과 가격 변동으로 인한 한계가 존재하기 때문에 이를 보완할 수 있는 제도적 장치가 마련되어야 한다. This study used System Dynamics to analyze the impact of slow steaming and the introduction of alternative fuel propulsion ships on the reduction of vessels’ CO2 emissions. Based on the fuel consumption and operation data of container ships in 2022, one scenario for slow steaming and 12 scenarios for alternative fuel use were established to calculate CO2 emissions and fuel costs over a 10-year period. As a result of the analysis, it was found that the effect of reducing CO2 emissions and fuel costs caused by slow steaming was insignificant. On the other hand, when LFO and HFO, which are existing fuels, are replaced with LNG, the effect of reducing CO2 emissions has been shown to be large, but fuel costs have also increased. In the case of propane gas, it was confirmed that both fuel cost and CO2 reduction effect were lower than that of LNG. From a short-term perspective, slow steaming are effective in reducing emissions, but alternative fuel propulsion ships should be introduced from a long-term perspective because slow steaming are likely to increase operating time and cost. However, there are limitations due to instability in the supply and demand of alternative fuels and price fluctuations, so an institutional mechanism to compensate for them should be prepared.

박소영,강세원,황희주,정종민,송대권,박홍석,한연수,이준상,강정하,이용석,Park, So Young,Kang, Se Won,Hwang, Hee Ju,Chung, Jong Min,Song, Dae Kwon,Park, Hong Seog,Han, Yeon Soo,Lee, Jun-Sang,Kang, Jung-Ha,Lee, Yong Seok 한국패류학회 2016 The Korean Journal of Malacology Vol.32 No.2

The natives of the genus Corbicula have shown worldwide dispersion in recent times, which has caused great ecological and economic impacts on the introduced ecosystems. The species reported from the genus have been consumed as food and explored for medicine with pharmacological activity. Consequently, the demand of Corbicula sp. in the South Korean domestic market has increased and so also it's associated import to the country. However, due to the absence of identification keys of imported Corbicula, the market is facing confronting situations. We hypothesized that the mitochondrial Cytochrome Oxidase I gene (CO-I) based molecular profiling could be a necessary technique for identification of Corbicula sp. in the South Korea domestic market. The genetic analysis identified both Corbicula japonica and Corbicula fluminea from the market foods. C. japonica and C. fluminea are inhabitants in Korea, but C. fluminea production has decreased in Seomjingang river basin. Therefore, C. fluminea identified from this study, is expected to be imported from China and would have a mixed sales in Seomjingang river side basin. CO-I서열의 생물정보학적 분석 결과 국내에서 유통되는 재첩류의 연체부는 일본재첩 (C. japonica) 과 재첩 (C. fluminea) 으로 동정되어 두 종이 혼재하여 유통되는 것으로 확인되었다. 일본재첩 (C. japonica) 과 재첩 (C. fluminea) 은 국내에서 서식하고 있으나, 섬진강 유역의 재첩 (C. fluminea) 은 개체수가 감소하여 거의 생산되지 않고 있으므로, 본 연구를 통해 확인된 재첩 (C. fluminea) 은 중국 수입산으로 예상된다.

Background Brassinosteroids (BRs) are a class of phytohormones with important roles in regulating physiological and developmental processes. Small RNAs, including small interfering RNAs and microRNAs (miRNAs), are non-protein coding RNAs that regulate gene expression at the transcriptional and post-transcriptional levels. However, the roles of small RNAs in BR response have not been studied well. Objective In this study, we aimed to identify BR-responsive small RNA clusters and miRNAs in Arabidopsis. In addition, the effect of BR-responsive small RNAs on their transcripts and target genes were examined. Methods Small RNA libraries were constructed from control and epibrassinolide-treated seedlings expressing wild-type BRI1-Flag protein under its native promoter in the bri1-5 mutant. After sequencing the small RNA libraries, differentially expressed small RNA clusters were identified by examining the expression levels of small RNAs in 100-nt bins of the Arabidopsis genome. To identify the BR-responsive miRNAs, the expression levels of all the annotated mature miRNAs, registered in miRBase, were analyzed. Previously published RNA-seq data were utilized to monitor the BR-responsive expression patterns of differentially expressed small RNA clusters and miRNA target genes. Results In results, 38 BR-responsive small RNA clusters, including 30 down-regulated and eight up-regulated clusters, were identified. These differentially expressed small RNA clusters were from miRNA loci, transposons, protein-coding genes, pseudogenes and others. Of these, a transgene, BRI1, accumulates small RNAs, which are not found in the wild type. Small RNAs in this transgene are up-regulated by BRs while BRI1 mRNA is down-regulated by BRs. By analyzing the expression patterns of mature miRNAs, we have identified BR-repressed miR398a-5p and BR-induced miR156g. Although miR398a5p is down-regulated by BRs, its predicted targets were not responsive to BRs. However, SPL3, a target of BR-inducible miR156g, is down-regulated by BRs. Conclusion BR-responsive small RNAs and miRNAs identified in this study will provide an insight into the role of small RNAs in BR responses in plants. Especially, we suggest that miR156g/SPL3 module might play a role in BR-mediated growth and development in Arabidopsis.

식민지 여성 통역사 : 말린체와 배정자

Interpretation is “the oldest job of human beings.” However, the interpretation studies have been relatively a few compared to translation studies. And the study on interpreters is also very limited in comparison to that on translators. On the other hand, todayinterpreters are acknowledged as one of “the best job” for women. Nevertheless, there were the times when female interpreters were regarded as a spy, a potential betrayer of secrets, and a traitor against the nation. Accordingly, this research focused on the role and identity of female interpreters in the colonies. More specifically, La Malinche, the interpreter during the conquest of Aztec Empire in 1500s and Bae Jeong-ja, who worked as an interpreter during the early colonization of Chosun Dynasty by Japan in 1900s, were reassessed from the historiographic point of view.

박소영,이유진,나태윤 대한안과학회 2023 대한안과학회지 Vol.64 No.2

Purpose: To report the first domestic case of orbital eccrine hidrocystoma. Case summary: A 40-year-old man visited our clinic after an orbital mass was discovered in the left eye. Orbital magnetic resonance imaging showed a well-defined 1 cm mass on the superomedial side of the orbit, slightly posterior to the globe. The mass was excised completely without rupture through an incision to the upper eyelid skin. The mass appeared more like a cyst than a hemangioma. The diagnosis of eccrine hidrocystoma was confirmed histopathologically. The patient recovered and there was no recurrence at the 6-month follow-up. Conclusions: Although orbital eccrine hidrocystoma is very rare, it should be included in the differential diagnosis of orbital tumors. 목적: 안와에 생긴 에크린한선낭종을 국내 최초로 보고하고자 한다. 증례요약: 40세 남자 환자가 건강검진에서 우연히 발견된 좌측 안와 내의 종괴로 내원하였다. 안와 자기공명영상검사에서 경계가 분명한 직경 약 1 cm 크기의 종괴가 좌측 안구의 약간 후방에서 안와의 내상방에 위치하고 있었다. 위눈꺼풀 피부 절개를 통한 종양제거술을 시행하였고, 피막 파열 없이 완전 적출하였다. 수술 당시 종괴는 혈관종의 양상이 아닌 낭종의 형태를 보였으며, 병리조직검사에서 에크린한선낭종으로 진단되었다. 환자는 잘 치유되었으며, 술 후 6개월 까지의 경과 관찰 동안 재발 소견은 없었다. 결론: 안와의 에크린한선낭종은 매우 드물지만, 안와에 생길 수 있는 종양의 하나로서 감별되어야 할 것으로 여겨진다.
