  • Background: Ginsenosides accumulation responses to temperature are critical to quality formation in cold-dependent American ginseng. However, the studies on cold requirement mechanism relevant to ginsenosides have been limited in this species. Methods: Two experiments were carried out: one was a multivariate linear regression analysis between the ginsenosides accumulation and the environmental conditions of American ginseng from different sites of China and the other was a synchronous determination of ginsenosides accumulation, overall DNA methylation, and relative gene expression in different tissues during different developmental stages of American ginseng after experiencing different cold exposure duration treatments. Results: Results showed that the variation of the contents as well as the yields of total and individual ginsenosides Rg1, Re, and Rb1 in the roots were closely associated with environmental temperature conditions which implied that the cold environment plays a decisive role in the ginsenoside accumulation of American ginseng. Further results showed that there is a cyclically reversible dynamism between methylation and demethylation of DNA in the perennial American ginseng in response to temperature seasonality. And sufficient cold exposure duration in winter caused sufficient DNA demethylation in tender leaves in early spring and then accompanied the high expression of flowering gene PqFT in flowering stages and ginsenosides biosynthesis gene PqDDS in green berry stages successively, and finally, maximum ginsenosides accumulation occurred in the roots of American ginseng. Conclusion: We, therefore, hypothesized that cold-induced DNA methylation changes might regulate relative gene expression involving both plant development and plant secondary metabolites in such cold-dependent perennial plant species.

  • Since the introduction of Western concept of nursing to Korea in late 1880s, Korean nursing practice has evolved into Korean culture. The purpose of this study was to explore and identify similarities and differences in hospital nursing practice between Korea and the United States using the grounded theory method. The data were gathered from 15 Korean nurses working in U.S. hospitals using semi-structured, in-depth interview method. Major similarities in nursing practice between Korea and U.S. existed in the 7 domains that Benner indicated in 1984. The nursing administration system was also similar in both countries. On the other hand, differences existed in how nurses execute these domains of nursing practice. These are the roles of nurses. nurse aides and family members. and the interpersonal relationships, and problem presentation and problem-solving strategies. American family members rarely participated in the patient's bedside nursing care, while Korean family members actively participated. American nurse aide participated in direct patient care, while Korean nurse aides did not. Also Korean nurses were participated more in administering and managiang the patient's diagnostic and treatment modalities, while American nurses foucused on the needs and demands of the patient. In terms of interpersonal relationships, American patients were more self-centered and demanding than Korean. American nurses focused more on the right of individuals while Korean nurses were more oriented to harmony with the coworkers. With inferiors and superiors, American members were more egalitarian, while Koreans tended to be hierachical. In ways of suggesting problems, American nurses tended to pick out the problems more frequently than Korean nurses did.. As to ways to solve the problems, American nurses relied heavily on explicit verbal explanations, while Korean nurses relied more on bodily action and behaviors. The results of this comparative study contribute to nursing by adding knowledge on the theory of culture care by describing the similarities and differences in nursing practice between Korea and the United States.

  • The purpose of this research was to compare the evaluation of tone on tone coloration of traditional Korean dress by Korean and American women college students. The respondents were asked to evaluate 48 stimuli of the traditional Korean skirt and jacket with different tone of color. The evaluation of Korean and American students admit of various interpretation, and it can'be said that they were caused by their different cultural bacgrounds. The results of reseach can be summerized as follows. As to the red colors, Korean students evaluated vivid skirt and light or dark jacket, light skirt and vivid or dull, dark jacket, dull skirt and light jacket as harmonized. But American students judged light skirt and dull and light jacket as not harmonized. As to the yellow colors, both Korean and American students had common opinions that light skirt and dull jacket are well harmonized. Korean students thought vivid skirt and dull jacket, light skirt and dull, dark jacket, dull skirt and dark jacket are well harmonized. American students thought light skirt and vivid, light, dull jacket dull skirt and light jacket are well harmonnized. As to the green colors, Korean students evaluated vivid skirt and dull, dark jacket, light skirt and vivid, dull, dark jacket are well harmonized. But American students evaluated vivid skirt and light jacket, light skirt and dark jacket, dark skirt and vivid or light jacket are not harmonized. Among 48 stimuli of tone on tone coloration, Korean students evaluated 18 set and American students judged 30 set as harmonized.

  • Since the beginning of her dramatic career, Suzan-Lori Parks has considered digging up and restoring African-American history buried under the dominant white Anglo-Saxon history as her mission as a playwright. In Red Letter Plays, she attempts what Deborah Geis called "canon-critique" by taking canonical work by Nathaniel Hawthorne and casting an African-American character as the main character and describing her oppression as an African-American female. This paper argues that Suzan-Lori Parks accuses the oppressive social system by restoring and representing the history of sexual, economic, and racial exploitation that African-American females had to suffer through the dominant image of body and blood. Parks had to rewrite the history of black female characters on their bodies and in the blood because their bodies have been the ultimate object of revulsion and attraction in the perspective of white male. While abhorring and despising Hester La Negrita's abject body, male characters in In the Blood nonetheless not only exploit her sexually and economically but also impregnate her. Hester resorts to her only means of revolting against this oppressive system; she kills her most beloved son and writes "A" on the floor with his blood. Likewise, Hester Smith in Fucking A, who wears "A" on her bosom like Hester Prynne, which in this case means "abortionist," "saves" her son from the hunters by slitting his throat. Abundant graphic and sensational images written on black female body and in the blood are Parks's dramatic strategy to rewrite the forgotten and hidden history of black women's history.

  • 복합민족국가 미국의 신속한 국가정체성 확립을 위한 주요 시발점이 되었던 대통령기록관은 미국이라는 한 자본주의 국가가 자신의 대통령을 기념하는 방법이다. 이것은 분명 미국이기에 가능했고, 또한 미국이기에 이해되는 것들이기도 했다. 미국이 대통령기록관시스템을 통해 그 어떤 행정기록보다 풍부한 자원을 확보하고 이용 가능하게 한 것은 엄연한 사실이다. 그러나 기록보다는 박물 전시에 치중하며, 이를 통해 국가적 애국심을 고착시키며 야기 시켰던 역기능들은 여전히 간과할 수 없는 요소들로 자리하고 있다. 이집트에 고대 파라오를 위한 피라미드가 있다면, 미국에는 전직 대통령을 위한 성전인 대통령기록관이 있다는 역사가들의 비유는 미국 대통령기록관이 자의적 역사해석을 통해서 퇴임 대통령을 긍정적으로 그리기 위해 얼마나 극도로 노력해왔는지를 보여준다. 그 영웅화가 가능하게 된 배경에는 미국식 소유관념과 미국식 낙관주의 문화가 있었음을 배제할 수 없다. 미국대통령기록관이 비록 그들의 방식으로 제도화하고 발전되었지만 거기에는 우리가 기꺼이 배울 점도 있고, 도저히 따라가서는 안 되는 점도 공존한다. 여기서 중요한 것은 균형 잡힌 시각으로 외국 사례를 수용하고 제대로 직시하는 시야를 갖는 것이다.

이야기를 통한 치유: 린다 호건의 『세상을 지켜보는 여자: 한 원주민의 회고록』 (Healing through Storytelling: Linda Hogan's The Woman Who Watches Over the World)

  • In Woman Watches over the World, Linda Hogan explores the broken identity of herself and her family, the issue of the poverty and the identity crisis, the alcoholism, prevalent in the Native American community and their silenced history. Previous studies have claimed that her memoir contributes to the restoration of Native American identity and history by accusing the violence of white culture, and seeks to recognize a dialogue between native culture and white mainstream culture as well. However they seem to overlook the complicated relations among story, identity, body and nature, to which Hogan as a multi-binded storyteller resorts as a way to break the silence of herself and her tribe for healing. Her own story, as a way to break the silence, becomes the formative drive to reveal the silenced history of her own tribe to lead the young generation to the future. She also understands the formative function of the story, which becomes the vehicle for embodying and connecting themselves to nature. To her, healing lies in the restoration of sympathetic relationship with nature. History, as a type of story, can be made up or mistold just like a story. There may be a blind spot where one can not assess what is true. In spite of the vision of the parallel worlds of the two cultures she presents, there seems to be no immediate solution to the discrimination against the Native American, poverty, identity crisis, and environmental problems which the Native American community faces. However, it can be said that her memoir serves as a rudder by presenting a direction to not only the Native American but also to readers in other cultures in its quest for practical possibilities for the future.

  • In Jesmyn Ward's 2017 novel, Sing, Unburied, Sing, Ward places herself within the modern African American literary tradition and lays out the unending "historical traumas" of blacks and cultural haunting in her narrative. She brings to the fore the story of a young black boy and demonstrates the difficulty of living while a black man in the American rural South. Living or dead, black males remain spectral as their frustrated black bodies are endlessly rejected and disembodied. It's through Ward's close attention to the notions of black masculinity and retrieval of (black) humanity that the black South is remembered, recuperated, and historicized. Shrewdly enough, Ward expands it further into the tradition of American literature. Instead of singularizing African American identity and its historical traumas, she renders them the part of American history and universalizing the single black story as the story of the American South. Filling in the gaps that Faulkner and other white writers have left in their novels, Ward writes stories about the unspeakable, the invisible, the excluded to deconstruct white narratives and rebuild the American history; and reasserts African roots and history, spirituality, black raciality and locality within the American tradition. I examine the symbolic significance of Jojo's claim of black masculinity within the socio-political contexts of contemporary America. I also look closely at Ward's portrayal of Jojo's black family genealogy on account of its traumatic experiences of incarceration in notorious Parchman Farm. Locating Jojo as the inspiration of linking the past and the present, the unburied and the living, I contend that Ward creates "home" for blacks in an atemporal oceanic space where the past and the present are able to meet simultaneously. I argue that the oceanic space is an alternative space of affect that functions against the space of white rationality.

  • L.M. Montgomery's Anne of Green Gables is not only confidently labelled a Canadian classic but also placed as a national icon along with the moose, the beaver, and the Habs in Canada. Anne's 'Canadianness' is partly due to its location in the rural world of Prince Edward Island. The fictional Avonlea is described as the ideal space where Canadian spirit can interact with the personified surrounding landscapes through Celtic imagination. Additionally, the communal bond of Avonlea fully demonstrates Scottish Canadian identities. The Scottish national character of Avonlea is responsible for clannishness of the Cuthberts and the Lyndes. The disrespect to the French is also due to Scottish heritage in Avonlea. As an outsider Anne wants to be integrated into the community of Avonlea, and successfully adapts herself to the regional shared values. Meanwhile she partly challenges the strictness and rigidness of the born Canadian Avonlea residents. Despite its Canadian origin, Anne of Green Gables is accepted as part of the American canon of children's literature in the Unite States. The configuration of Anne as an American heroine is noticeable among American scholars: by relocating it to the US the female Bildungsroman in the nineteenth century America, a group of literary critics adapt Anne as an American girl for American readers. The heroine of Anne of Green Gables is linked to American novels such as Louisa May Alcott's Little Women, Kate Douglas Wiggin's Rebecca of Sunnybrook Farm and Gene Stratten Porter's A Girl of the Limberlost. Anne is even classified as another Caddie by American literary critics: Anne is placed at the center of Caddie Woodlawn Syndrome as another Wisconsin pioneer child. Canadian identity of Anne is intentionally excluded and Anne was reborn as an American girl in the U.S. In this context, Anne functions as a sign of nation and a site for cross-national identity formation.

  • This essay aims to examine chick lit written within the Asian American context. For the most part, the chick lit genre has been typically regarded as a site to study contemporary white women's experiences and to debate the genres' credentials as feminist literature. Though some may disagree, there is general consensus that chick lit has fallen out of vogue after reaching its peak in the first decade of the new millenium.; nevertheless, it is being revisited by readers and critics alike as it has recently re-emerged as a location upon which to examine how race and gender inform notions of national belonging and female subject formation in the twenty-first century. To this end, this essay reads Kim Wong Keltner's The Dim Sum of All Things (2004). Keltner's protagonist Lindsey Owyang is yet another twentysomething "chick" looking for love, self, independence, and success in the huge megalopolis of San Francisco. What sets Lindsey apart from the chick prototype is that she is a third-generation ABC (American-born Chinese) and issues relevant to Asian America frequently make their way into Lindsey's narrative. Though it is generally considered as standing a "few notches above the standard chick-lit fare" (Stover n. pag), I would argue that meaningful reflections on many of the major pillars of Asian American literature, history, and cultural politics are glossed over in favor of cursory musings about the daily vicissitudes of Lindsey's life. This essay thus takes to task Ferriss's claim that a "serious" consideration of chick lit "brings into focus many of the issues facing contemporary women and contemporary culture - issues of identity, of race and class, of femininity and feminism, of consumerism and self-image" (2). I contend that a close examination of Keltner's The Dim Sum of All Things discloses that the chick lit format undermines a "serious consideration" of Asian American issues by presenting in particular a highly problematic representation of race and of Asian American femininity.

  • A new cultural practice for commercial production of American ginseng by organically grown in a shaded greenhouse under controlled environment conditions has been developed. This new procedure will shorten the dormant period and reduce the cultivation period from 4 years in conventionally grown ginseng to 2 years.
