Aging is the process spontaneously occurred in living organisms. Cardiac fibrosis is a pathophysiological process of cardiac aging. Mangiferin is a well-known C-glucoside xanthone in mango leaves with lots of beneficial properties. In this study, rat model of cardiac fibrosis was induced by injected with 150 mg/kg/d D-galactose for 8 weeks. The age-related cardiac decline was estimated by detecting the relative weight of heart, the serum levels of cardiac injury indicators and the expression of hypertrophic biomakers. Cardiac oxidative stress and local inflammation were measured by detecting the levels of malondialdehyde, enzymatic antioxidant status and proinflammatory cytokines. Cardiac fibrosis was evaluated by observing collagen deposition via masson and sirius red staining, as well as by examining the expression of extracellular matrix proteins via Western blot analysis. The cardiac activity of profibrotic TGF-β1/p38/MK2 signaling pathway was assessed by measuring the expression of TGF-β1 and the phosphorylation levels of p38 and MK2. It was observed that mangiferin ameliorated D-galactose-induced cardiac aging, attenuated cardiac oxidative stress, inflammation and fibrosis, as well as inhibited the activation of TGF-β1/p38/MK2 signaling pathway. These results showed that mangiferin could ameliorate cardiac fibrosis in D-galactose-induced aging rats possibly via inhibiting TGF-β/p38/MK2 signaling pathway.

경계인으로서의 윤동주와 본향의 자리

윤지은(Yun, Ji-eun) 한국근대문학회 2017 한국근대문학연구 Vol.18 No.2

윤동주와 그의 시세계를 재구성하는 과정에서 주목되는 것은 그에게 영향을 준 외부적 요인을 살피는 작업이다. 이 작업은 윤동주 작품의 창작 시점과 발표 시점이 시차를 갖기 때문에 당대의 맥락을 필수적으로 살펴야 한다는 점, 과작을 했던 만큼 시인의 시세계 전반을 구성하기 위해서 영향관계에 있던 요인을 빠짐없이 조망할 필요가 있다는 점 등에서 중요하다. 이러한 문제의식에서 출발하여, 본고는 윤동주의 애송가 〈黑人의 望鄕歌〉를 새롭게 소개함으로써 시인의 이력을 세밀하게 조직해보고자 했다. 번안곡인 〈黑人의 望鄕歌〉는 미 대륙에 끌려온 아프리카 흑인노예가 그의 고통을 위로받을 공간인 유토피아적 고향을 불러내는 노래다. 나아가 노래와 시의 관련성을 토대로 윤동주 시에 나타난 ‘고향’의 의미를 해명하였다. 윤동주 시에서 고향은 부조리한 현실을 뛰어넘어 진정한 자유를 성취할 수 있는 미래에 대한 욕망을 포함한 공간이다. 이 공간은 ‘진정한 고향’ 혹은 ‘본향’으로 구체화된다. 제국 일본과 식민지 조선, 그리고 간도라는 중층의 경계를 의식했던 윤동주에게 ‘진정한 고향’을 형상화하는 것은 현실에 저항하고 시대를 전복하려는 혁명적인 시도였다. The external factors that affected Yun Dong-ju’s poetry and poetics attract much attention when we study his poetry. The most important of such external factors is the contemporary context of Yun’s writing. This is because the time when he composed poetry was different from the time when he published it. Furthermore, the poet’s works are few, thus the external factors must be carefully examined iso that we can construct Yun’s whole poetry. Taking this issue of order of composition as its starting point, this paper discovered Yun’s favorite song 〈黑人의 望鄕歌〉, and organized his career in detail. 〈黑人의 望鄕歌〉 was a song based on African-American Spiritual 〈Carry me back to old Virginny〉. This song is about black slaves in America wishing to return to their homeland. Based on the relationship between 〈黑人의 望鄕歌〉 and Yun’s poetry, this paper explains the meaning of ‘home’ in Yun Dong-ju‘s poetry. In Yun’s poetry, home is a place that embeds the desire for the future that can achieve true freedom beyond the absurd reality. Yun Dong-ju defines this space as the ‘true home’ or ‘homeland’. It was a revolutionary attempt to overthrow the era’s oppressors and resist their reality, who was conscious of the boundary between the imperial Japan, the colonial Joseon, and Gando.

조형예술의 측면에서 본 윤이상의 주요음(향)작곡

윤신향 한국음악학학회 2004 음악학 Vol.11 No.-

This study tries to investigate the relation between maintone(sound)-composition of Isang Yun and formative arts. The first two chapter summerize the music historical primise for the integrative-artistic aesthetic and the process of establishment of Isang Yuns identity as a composer in europe. Therby it is characteristic, that Yun is interested in the relation between music and pictures, while the western composers in the 1950s deal with graphical music and accidental music: the compositional situation tends to weaken the traditional note system, to expand the traditional instrumental medium, and to dismantle the traditional genre. The third chapter describes the relation between the formative image of west side in the acient tomb mural 'Sasindo', which is an about 1500 years old Korean traditional heritage. The line image of this mural is similar with the line image, which Yun draws in the dialog with the japanese composer Nishimura Akira about his maintone(sound)-model. An archetype of this line image is implemented in the beginning of the piece <flute-etu¨de>(1974) in the first section, and it is transformed in the beginning of the fifth section of the same work. Specially amorphous form ending of the maintone(sound)-model displays in this part an expanded form. The expansion of the amorphous form at the end of the maintone-model occurs also three times in <Re´ak>(1966). It is deduced, that this amorphous part form shaws alike in <Images> as a connecting part of the sound-surface. The last two chapter deal with the means of change the Korean traditional format image to modern sound. Yun saw always the picture of the mural in his living room and emphasized the line image of this picture in the explanations of his work, and draw this form in the air in the introduction of play. This phenomen is interpreted under two aspects: at one hand side, the image depicts the taoistic thouhgt, which Yun himself wont to identify with his work. On the other hand side, the connection of Yun's music with a Korean traditional image shaws the fusion aspect of composer. The formative essence of maintone(sound) based on spatial form. The formative mean is created through tile fusion of the line and colorful images. This aura of an image is consistently and endless open. As a result, his maintone(sound) -composition can be interpret as a try to form of an Asian image in the real space 'modern'.

He concentrated especially on Taoism. Idea of `Hauptton` which is basis of Isang Yun`s music originated from Eastern sound concept. Therefore, this thesis will be discussed on musical presentation and Taoism that are indulged in Isang Yun`s music through "Interludium A". This piece was created with creativity and unique characteristics of Isang Yun. His life in Korea and Europe, style of music during his life time, what is Taoism and balance of yin and yang, and analysis of hauptton in each parts will be discussed to prove the understanding and hidden meaning of "Interludium A".

윤이상의 <고풍의상>: 박, 박자 및 리듬적 특징 연구

주윤영 ( Yun Young Joo ) 세계음악학회 2012 음악과 문화 Vol.27 No.-

Yun`s early art song <Traditional Attire> successfully represents the rhythmic characteristics of Korean traditional music, which is the coexistence of duple and triple meter in musical time. However, it has never been studied in depth. Thus, this paper will discuss how Yun brought out the rhythmic characteristics of Korean traditional music, not depending on any particular changddan (rhythmic patterns of Korean traditional music), and rhythmic features of the Korean text within the musical texture. In the course of the study, "Si-Jo," one of the three genres of traditional Korean classical art song, will be mentioned, and Pyongsijo <Dong-chang-i> will be examined to provide background discussion.

Yun, Taik-Koo,Lee, Yun-Sil The Korean Society of Ginseng 1994 Journal of Ginseng Research Vol.18 No.3

In this study, we investigeated the anticarcinogenicity of various types and ages of ginseng extracts as an extended study using Yun's anticarcinogenicity test. Fresh ginseng at 1.5, 3, 4, 5 and 6 years was dried and powdered. And white ginseng was processed in the same way that of fresh ginseng after removal fo the ginseng cortex and fine root. For red ginsneg, fresh ginseng was steamed and dried. Each ginseng powder was extracted and extracts was freeze dried. Newborn N:GP(S) mice were given a single subcutaneous injection of 0.5 mg of benzo(a)pyrene(BP). Various types and ages of ginseng extracts at 2.5mg/ml were orally administered. All the mice were sacrificed at the 9th week. The following results were obtained. In the dried fresh ginseng extract treated group, the incidence of lung adenoma induced by BP was 63.9% and its incidence was reduced to 48.3%, 52.5%, 51.8%, 47.5% and 44.1% after co-treatment with 1.5, 3, 4, 5 and 6 year-dried fresh ginseng, respectively. The incidence of lung adenoma induced by BP on the white ginseng extract treated group was 41.3% and decreased to 31.0%, 46.0%, 44.0% and 26.5% after co-treatment with 3, 4, 5 and 6 year-white ginseng, respectively. In the red ginseng extract treated group, the incidence of lung adenoma induced by BP was 47.5% and its incidence diminished to 40.7%, 35.0%, 30.1%, 30.0% and 26.3% after co-treatment with 1.5, 3, 4, 5 and 6 year-red ginseng, respectively. From the above results, we concluded that a statistically significant anticarcinogenic effect was observed in extracts of 6 year-dried fresh ginseng, 6 year-white ginseng, and 4, 5 and 6 year-red ginseng and it is suggested that the anticarcinogenicity of ginseng varies according to the types and ages Key words Ginseng extract, types and ages. anticarcinogenic, newborn mice, lung tumor.
