This paper suggests a numerical method for valuation of American options under the Kou model (double exponential jump diffusion model). The method is based on approximation of underlying asset price using a finite-state, time-homogeneous Markov chain. We examine the effectiveness of the proposed method with simulation results, which are compared with those from the conventional numerical method, the finite difference method for PIDE (partial integro-differential equation).

The purpose of this study is to examine the relative distances among English front vowels in a message produced by 47 Korean and American speakers in order to better instruct pronunciation skills of English vowels for Korean English learners. A Praat script was developed to collect the first and second formant values(F1 and F2) of eight words in each sound file which was recorded from an internet speech archive. Then, the Euclidean distances were measured between the three vowel pairs: [i-ɛ], [i-ɪ], and [ɛ-æ]. The first vowel pair [i-ɛ] was set as the reference from which the relative distances of the other two vowel pairs were measured in percent in order to compare the vowel sounds among speakers of different vocal tract lengths. Results show that F1 values of the front vowels produced by the Korean and American speakers increased from the high front vowel to the low front vowel wih differences among the groups. The Korean speakers generally produced the front vowels with smaller jaw openings than the American speakers did. Secondly, the relative distance of the high front vowel pair [i-ɪ] showed a significant difference between the Korean and American speakers while that of the low front vowel pair [ɛ-æ] showed a non-significant difference. Finally, the Korean speakers in the higher proficiency level produced front vowels with higher F1 values than those in the lower proficiency level. The author concluded that Korean speakers should produce the front high vowels distinctively by securing sufficient relative distance of the formant values. Further studies would be desirable to examine how strong the Korean speakers' English proficiency correlate with the relative distance of target words of comparable productions.

The purpose of this research was to investigate the difference in fabric preference of formal wear attire between the Korean and American female consumers. For such purpose, fabrics which were used in the womens formal wear market of Korean(n=25) and U.S.A.(n=25) in the 1999 spring/summer season were collected from different fabric converters of the two countries. The respondents were comprised of 50 Korean and 50 U.S.A. female volunteers in the age group of 20s and 40s. A 5 point Likert Scale was used to evaluate the degree of the \"like\" preference of fabrics. T-test and Spearmans rho statistics were conducted for data analysis. The followings are the results. 1. Korean 20s and American 20s preferred Korean fabrics but Korean 40s and American 40s preferred U.S.A. fabrics. 2. Generally, the 20s preferred greyish or tone down color, whereas the 40s preferred both greyish and colorful fabrics. 3. Koreans preferred melange colored fabrics as well as solid color fabrics. 4. Americans liked knit fabrics as well as woven fabrics for formal wear and 20s liked compact density fabrics compared to the 40s age group.age group.

This study is to compare the prevalence of obesity between Korean-American children and Korean children, and to investigate the role of environmental factors in obesity development. Prevalence of child obesity is compared by their residence, parents' anthropometric data, education and occupation, and the length of immigration, and birth place of the children. A total of 593 children between the ages of 9 and 12 were examined. 262 Korean-American children (KcUS group) from New Jersey, USA and 331 Korean children (KcK group) from Seoul, Korea were compared. KcUS group showed a higher obesity rate (male: 12.6% and female: 8.2%), compared to KcK group (male: 8.0% and female: 5.1 %). KcK male children showed lower weight and prevalence of obesity than Korean-American male children who lived in the United States for more than three years. Korean-American female children had higher weight and obesity rate than Korean female children. Waist circumference and hip circumference were also higher in obese children in both KcK and KcUS groups. The children who live in America had an odds ratio of 1.69 to be obese compared to KcK, while those born in America and those who have lived in America for more than 3 years had odds ratios of 1.53 and 1.25 to be obese, respectively. This study found that environmental factors, immigration to America for instance, could playa bigger role in child obese development than the genetic factor.

Sung Yung Shin was adopted as a Korean infant to an American family. She is now one of the most important writers in Asian American literary field. This paper analyzes the characteristics of her literature, focusing on Skirt full of Black (poetry)and Cooper's Lesson(children's book). Sun Yung Shin uses collage in Skirt full of Black as an effective rhetorical device because it can express her experience as an adopted other in the multicultural American society. She rewrites the fairy tale of Swan Prince in the viewpoint of silence. For a yellow Asian adopted woman, speaking is suppressed. In the end, the attempt to escape from silence is the writer's resisting activity, and the rewriting of the tale is her questioning in place of the princess. I analyses Cooper's Lesson in the viewpoint of transcultural assimilation. Cooper's lesson is accomplished not by his white father but by a Korean settler, Mr. Lee. Cooper's family is a hybrid composed of white American father, Korean mother, and their half son. So this family has many complicated difficulties, though it's small. Mr. Lee who accepted a new language to establish a new identity teaches Cooper the importance of cultural assimilation, which is not a one-sided integration to dominant culture but an intercultural communion while sustaining each culture's singularity. Cooper learns that he should live in an harmonious and balanced life in a multi-cultural society while keeping his own subjective point of view.

Multicultural theories fully fledged around the 1980s and the early 1990s. Emerging in the 1960s thanks to the Civil Rights movement, multiculturalism has become the grand American national narratives, whose tenets recognize and respect people with diverse racial and cultural backgrounds. This period, however, witnessed the eruption of violent and destructive rebellions or uprisings involving racial minorities. Racial conflicts and tensions exploded at the moment when multiculturalism was widely practiced in areas including education and public policy revealing that complicated problems are embedded in the urban ghettos. American popular culture, specifically addresses antagonisms among different races or ethnicities in Bed-Stuy in New York. Although the film is mainly concerned with the collision among races, it lets ambivalent and cacophonous values and ideologies be present in the black community. On the other hand, Ice Cube's "Black Korea" empowers the black community when it deals with the turbulent relationship between black residents and Korean American merchants. Simultaneously, it denigrates Korean Americans as gasta raps often target the institution like government or police. In short, while attempts to search the ideas of coexistence and juxtaposition through polyphonic features embodied in the film "Black Korea" seems to depend on the dualistic system when it deals with the black-Korean conflicts and as a result it just reveals the chasm between two communities.

This paper examines the benefits of teaching The Adventures of Wu Han of Korea in secondary education in Korea. The novel is a rare sample of twentieth-century American fiction that features a Korean protagonist. What is notable in this novel is that its major Korean characters seem to share the mindset of their American author and creator and represent the Western perspective in their discourse of Korean/Eastern idea and culture. The novel is packed with Orientalist attitudes and could be taught as a case study of Orientalism. Teachers can also use the novel to teach students the art of close reading by analyzing selected scenes from the text.

The South Korean ethnic diaspora US lobby shows efficacy as an interest group in generating influence in American foreign and domestic public policy making. The persuasive portrayal of South Korea as a critical Cold War US ally reinforced US amenability to pro-South Korea lobbying. Also, the South Korean US diaspora is a comparatively recent immigrant group, thus its lingering resistance to assimilation facilitates its political mobilization to lobby the US government. One source of this influence includes the foundational legacy of proselytizing Western and particularly American religious social movement representatives in Korean religiosity and society. US protestant Christianity acquired a strong public association with emerging Korean nationalism in response to Japanese imperialism and occupation. Hostility towards Japanese colonialism followed by the threat from Soviet-sponsored, North Korean Communism meant Christianity did not readily become a cultural symbol of excessive external, US interference in South Korean society by South Korean public opinion. The post-Cold War shift in US foreign policy towards targeting so-called rogue state vestiges of the Cold War including North Korea enhanced further South Korea's influence in Washington. Due to essential differences in the perceived historical role of American influence, extrapolation of the South Korean development model is problematic. US hegemony in South Korea indicates that perceived alliance with national self-determination constitutes the core of soft power appeal. Civilizational appeal per se in the form of religious beliefs are not critically significant in promoting American polity influence in target polities in South Korea or, comparatively, in the Middle East. The United States is a perceived opponent of pan-Arab nationalism which has trended towards populist Islamic religious symbolism with the failure of secular nationalism. The pronounced component of evangelical Christianity in American core community nationalism which the Trump campaign exploited is a reflection of this orientation in the US.
