New record of the red algae, Halarachnion parvum (Gigartinales) and Champia lubrica (Rhodymeniales), from Korea

양미연,Young Ho Koh,Myung Sook Kim 한국생태학회 2015 Journal of Ecology and Environment Vol.38 No.4

We report the first finding of Halarachnion parvum and Champia lubrica from Korea based on morphology and the plastid rbcL sequence analyses. H. parvum occurs in the subtidal zone of Munseom, the southern part of Jeju. Thalli have short stipe, and elliptical to ovate fronds with marginal proliferations of up to 3 cm in height. H. parvum has zonately divided tetrasporangia and cystocarp immersed under the cortical layer. Champia lubrica appears in Namhae, Gyeongnam and Seopseom, Jeju. Thalli are erect, irregularly branched, terete, obtuse apex, up to 3–5 cm high, and have tetrahedrally divided tetrasporangia. Molecular analyses of the plastid rbcL gene reveal that two species are clearly separated from other species of their respective genera. H. parvum is sister with Halarachnion latissimum in 3.1–3.2% sequence divergence, and C. lubrica is closely related to the sample from Japan with 0.2% sequence divergence.

Molecular Phylogeny of the Genus Chondracanthus (Rhodophyta), Focusing on the Resurrection of C. okamurae and the Description of C. cincinnus sp. nov.

양미연,김명숙 한국해양과학기술원 2016 Ocean science journal Vol.51 No.3

Determining the taxonomic status of the red algal genus Chondracanthus based on morphological characters is challenging due to the similarity and high degree of plasticity of the thallus. Since the taxonomic history of several Chondracanthus species remains unclear, we analyzed the plastid rbcL and mitochondrial COI genes of the specimens from Korea and Japan, in combination with morphological observations, to examine their phylogenetic relationships. Our results confirmed the distinction of C. okamurae, which is separated from C. intermedius, and identified a novel species, C. cincinnus sp. nov. Three species (C. okamurae, C. intermedius and C. cincinnus) formed a monophyletic clade with C. tenellus. C. okamurae is distinguished by linear, narrow, cylindrical to compressed, slightly recurved axes, and a high-intertidal to subtidal distribution. It was collected from Korea and Japan, while C. intermedius was identified from Japan only. A new species, Chondracanthus cincinnus sp. nov., is characterized by linear, compressed, strongly recurved axes, and a low-intertidal to subtidal distiribution. Based on the molecular phylogeny using rbcL and COI data, we herein resurrect C. okamurae as a distinct species and identify C. cincinnus as a new species.

Molecular analyses for identification of the Gracilariaceae (Rhodophyta) from the Asia–Pacific region

양미연,김명숙 한국유전학회 2015 Genes & Genomics Vol.37 No.9

The family Gracilariaceae contains economically important seaweeds and is well known as a difficult group for the species identification due to its high species diversity and uncertainty of species limits. To date, molecular studies of the Gracilariaceae in the Asia–Pacific region have been insufficient to determine the distribution and diversity of species. To acquire a better understanding of the species boundary and species diversity, we analyzed mitochondrial COI as DNA barcoding marker and plastid rbcL genes for specimens from the Asia–Pacific region. A total of 22 species has been recognized as a distinct entity including five unidentified and two new distribution records. COI sequence data showed more variation than rbcL data, enabling the clear discrimination of species. The range of intra- and inter-specific divergence for COI was 0–2.6 % (except 4.4 %) and 2.8–15.7 %, respectively. RbcL data showed the interspecific divergences ranged from 1.1 to 14.8 % and divided into two large clades, such as Gracilaria sensu lato and Gracilariopsis. The regional study allowed us to get the information of the geographic distribution of two species, Gracilariopsis chiangii from Taiwan and Hydropuntia perplexa from Australia, and reported for the first time their presence in Okinawa, Japan. The database of the Gracilariaceae has potential to speed up the identification of species diversity.

심부전 악화로 사망한 대유행 인플루엔자(H1N1 2009) 1예

양미연,박정환,이윤나,임재희,이은정,전민혁,김태형,추은주 대한감염학회 2010 Infection and Chemotherapy Vol.42 No.2

On April, 2009, pandemic influenza (H1N1 2009) emerged in the United States at first. Clinical outcomes of this infection are reported as ranging from self-limited illness to respiratory failure or death. There were more than 250 deaths due to pandemic influenza until March 2010. Influenza-related deaths occurred in the elderly and in patients with underlying medical conditions. Most of the critically ill patients showed severe hypoxia and acute respiratory distress syndrome and required ventilator care. We experienced a 70-year-old man presenting with pandemic influenza (H1N1 2009) with heart failure. He was treated with antival agents, ventalator and extracorporeal membrane oxygenation. But his heart function was aggravared and resulted in his death.

Molecular identification of Grateloupia elliptica and G. lanceolata (Rhodophyta) inferred from plastid rbcL and mitochondrial COI genes sequence data

양미연,한은규,김명숙 한국유전학회 2013 Genes & Genomics Vol.35 No.2

The marine red algae Grateloupia is the largest genus in the family Halymeniaceae and widely distributed from tropical to warm temperate regions of the world. In the genus Grateloupia, especially G. elliptica and G. lanceolata have common features of bladelike thalli with leather in texture and cruciately divided tetrasporangia. Due to this similar morphology, G. elliptica and G. lanceolata are frequently confused and resulted in considerable difficulty distinguishing these two taxa. We have reassessed the relationships between two species using molecular identification including plastid rbcL and mitochondrial COI genes to more accurately define their genetic diversity owing to the confusion of identification. As a result, the chloroplast-encoded rbcL sequence analyses support the distinction of two species, G. elliptica and G. lanceolata collected from Jeju Island, Korea and Japan at the species level, with interspecific divergence of 3.7-4.6 %. The genetic diversity of COI gene within species are estimated to be 0–0.3 % in G. elliptica and 0–1.0 % in G. lanceolata, respectively. The effectiveness of mtDNA COI barcoding in the identification for two species demonstrates in this study.

Molecular analyses and reproductive structure to verify the generic relationships of Hypnea and Calliblepharis (Cystocloniaceae, Gigartinales), with proposal of C. saidana comb. nov.

양미연,김명숙 한국조류학회I 2017 ALGAE Vol.32 No.2

The genera Hypnea and Calliblepharis of the family Cystocloniaceae are discriminated by their female reproductivestructure, especially in the formation of carposporangia and gonimoblasts. Hypnea saidana, once classified based onobsolete evidence, has not been studied phylogenetically using molecular analysis and detailed reproductive structurethough it shares many morphologic features with the genus Calliblepharis. To provide better understanding of genericrelationship of H. saidana with Hypnea and Calliblepharis, we carried out molecular analyses using the nuclear-encodedsmall subunit ribosomal DNA (SSU) and chloroplast-encoded large subunit of the RuBisCO (rbcL), and exact morphologicalobservations focusing on the reproductive structures of wild specimens. Our molecular phylogeny showed thatH. saidana is closely related to Calliblepharis, but distinct from the clade of Hypnea. Female reproductive structure ofH. saidana characterized by upwardly developing chains of carposporangia, central reticulum of cell, and gonimoblastfilaments not connected to the pericarp provides definite evidence to assign the taxonomic position of this species toCalliblepharis. Based on our combined molecular and morphological analyses, we have proposed Calliblepharis saidanacomb. nov., expanding the distribution of Calliblepharis habitat from the eastern Atlantic South Africa, the northern IndianOcean, Australasia, and Brazil to the western Pacific Ocean.

중국인 주관적 계층 인식의 영향 요인 -코로나 19의 유행으로 인한 소비 패턴의 변화를 중심으로-

양미연 중국학연구회 2023 중국학연구 Vol.- No.106

2019년 12월 중국 후베이성 우한시에서 유행하기 시작한 코로나 19는 중국인의 생활 방식 및 소비 패턴에 큰 영향을 미친다. 2020년 1월부터 중국 정부는 코로나 19의 유행을 최대한 통제하기 위해 공간 이동 및 개인 간의 접촉을 최대한 줄이는 봉쇄적인 격리 정책을 택했다. 이런 격리 정책으로 인해 중국인의 소비 패턴이 크게 변화한다. 그러나 이런 소비 패턴의 변화는 중국인의 주관적 계층 인식에 영향을 미치는지 아직 불명확하다. 주관적 계층 인식의 결정요인에 관해 서구에서 진행된 경험적 연구들은 주로 직업, 교육, 소득 등의 사회경제적 요인이 주관적 계층 인식의 주요 결정요인으로 강조하고 있다. 그러나 현대사회에서 주관적 계층 인식의 형성은 경제적 소유에 의해서만 결정되지 않고, 소비 패턴에 의해서도 좌우된다. 따라서 본 논문에서 중국인의 주관적 계층 인식이 코로나 19로 인한 소비의 변화에 어떤 영향을 받는지 연구하기 위해, 우선 사회경제적 요인 및 소비 패턴은 주관적 계층 인식에 어떤 영향을 미치는지에 관한 이론을 살펴보고자 한다. 다음에 코로나 19가 유행하기 전인 2018년과 코로나 19를 통제하기 위해 봉쇄적인 격리 정책을 실시한 2021년 중국 종합 사회 조사 자료(CGSS)를 이용하여, 중국인들이 코로나 19를 경험하면서 그들의 소비 패턴이 어떻게 변화했고, 이런 소비 패턴의 변화는 중국인들의 주관적 계층 인식의 변화에 있어 어떤 영향을 미쳤는지 살펴보도록 한다. 결론적으로 중국인의 현재 주관적 계층인식과 미래 속할 계층에 관한 주관적 인식에 있어, 문화 소비와 체육 소비는 코로나 19가 유행하기 전, 후 시기에 모두 정적 영향을 미친 반면에, 사회자본적 소비는 2018에만 정적 영향을 미친다. 미래 계층 상향 이동 가능성에 대한 믿음에 관해, 모든 요인을 투입한 경우에는 2018년에는 사회자본적 소비 요인만 정적 영향을 미쳤으나, 2021년의 경우에는 체육 소비만 정적인 영향이 나타났다.
