This study aimed to understand communicative and socialization practices of immigrant bilingual families in everyday learning situations by examining interactions between parents and children in the United States. Drawn on language socialization theory and socio-cultural factors influencing immigrants, this study explored how three Korean American mothers struggled as they helped their children with homework by interviewing the mothers and observing mother-child interaction during homework time. The study paid attention to the emotional values of immigrant parents that they tried to teach their children who are members in two distinctive communities, such as Korean American and mainstream American. The findings showed that parental socialization practices had effects on children's emotional and social competence and at the same time the socialization process was bidirectional. Mothers started with Korean values, but they faced challenges with the English language, different demands for American homework, and children's rejection of their attempts. Mothers needed to change their strategy and borrow American ways of keeping emotional distance from their children by acknowledging their independence. Their struggles are discussed with attention to their language choice and culture.

We consider the modulus-based successive overrelaxation method for the linear complementarity problems from the discretization of Black-Scholes American options model. The $H_+$-matrix property of the system matrix discretized from American option pricing which guarantees the convergence of the proposed method for the linear complementarity problem is analyzed. Numerical experiments confirm the theoretical analysis, and further show that the modulus-based successive overrelaxation method is superior to the classical projected successive overrelaxation method with optimal parameter.

This paper concerns barrier option of American type where the underlying price is monitored during only part of the option's life. Analytic valuation formulas of the American partial barrier options are obtained by approximation method. This approximation method is based on barrier options along with exponential early exercise policies. This result is an extension of Jun and Ku [10] where the exercise policies are constant.

Sanitary codes of retail ffod establishment of Korea, Japan, China, and America were reviewed in order to figure out the differences of the codes. The codes of Korea & Japan are similar in many aspects. The code of America regulates food safety procedures in detail and are easy to interpret. The code of China is broad and not specific in the procedures. Korean code deals with many administration affairs and Japanese code deals with food test and business. Chinese code also deals with administration and standards. American code defines 90 different terms while the codes of rest of the countries define only few terms. For sanitization American code specifies the procedures in specific terms in detail but others do not specify the procedures. For facilities, the American code specifies location, material and procedures but other codes also specify the material but the contents of the codes are not so much specific to compare with American code.

Korean export of fashion products to the U.S. has fallen off sharply after 2001. Now, Korean fashion companies have to develop higher value-added business. In the U.S., Korean-American fashion companies are taking a primary role in up-stream of the fashion industry. To cut the edge over the U.S. fashion companies, one of the solutions could be to build the business relationship with Korean fashion companies which reflect the recent trend rapidly and have high quality production. On this study, we investigated the marketing strategies of Korean-American fashion companies to seek to start business with Korean fashion companies and make suggestions for Korean fashion companies who want to enter into the U.S. market effectively. To analyze current situation of Korean export to the U.S. and the U.S. fashion industry, we considered various kinds of statistic data, publications and studies. And we performed in-depth interviews with 9 Korean-American fashion companies in LA from $9^{th}$ to $21^{st}$ of July. The results are as follows. first, Korean fashion companies should aim for high-end market with the products of high quality and design. Second, there should be professional agents who manage Korean small-medium fashion companies and connect them with Korean-American fashion companies. Third, Korean fashion companies who want to enter into the retail market of the U.S. have to decide the target market clearly and plan strategic and differentiated merchandising. Fourth, Korean fashion companies can specialize in product developing service like proposing a product or a merchandising line as a package including designs, fabric swatches, trims, production information, etc.

The saponins of two- and four-year-old American ginseng plants (Panax quinquefolium L.) (Araliaceae) collected in July and September were studied. American ginseng saponins (panaquilins) differ from Korean ginseng $(Panax ginseng\;C.A.\;M_{EYER})$ saponins (ginsenosides). The American ginseng saponins separated and named were panaquilins A, B, C, D, E-1, E-2, E-3, G-1, G-2, (c) and (d). One-dimensional thin-layer chromatography did not completely separate panaquilin mixture and was subject to misinterpretation. The panaquilins were more accurately separated and identified by the two-dimensional thin-layer method established. Some differences in American ginseng saponins were dependent upon the plant age, time of collection, and part extracted. The American ginseng sapogenin components are panaxadiol (panaquilins B and C), oleanolic acid (panaquilin D) and panaxatriol (panaquilin G-1). The panaquilins E-1, E-2 and E-3 mixture contained both panaxadiol and panaxatriol. The genins of panaquilins A, (c), (d) and G-2 were not identified. In addition, ${\beta}-sitosterol$ and stigmasterol were identified from the root ether extracts.

This study was conducted to obtain a better understanding of American green tea consumers for increasing Korean green tea sales in the US market. In doing so, this study investigated green tea choice attributes of US consumers and segmented them based upon their perceptions about important attributes of green tea. A factor-cluster segmentation approach was used for this study. An exploratory factor analysis identified five green tea choice motives: 'Sensory', 'Diet', 'Price', 'Health', and 'Brand'. Based upon these five choice attributes, cluster analyses classified all respondents into four homogeneous subgroups: 'Highly motivated', 'Taste/Price oriented', 'Health oriented', and 'Brand oriented'. Cross-tab tests proved that green tea consumption and purchasing patterns were significantly different among the four clusters. In particular, two cluster groups representing 'Highly motivated' and 'Health oriented' groups were found to offer the most utility for further American green tea market segmentation research. Findings show that American green tea consumers include a wide range of age groups and they usually buy green tea at grocery markets. Managerial implications for all cluster groups based upon their unique characteristics are provided. Korean green tea companies can apply these findings in order to develop more effective and efficient marketing strategies to attract American consumers to buy more Korean green tea.

The sapogenins of two-and four-year-old A-merican ginseng plants (Panax quinquefolium L.) (Araliaceae) collected in July and September were studied. American ginseng saponins (panaquilins) differ from Korean ginseng (Panax ginseng C. A. Meyer) saponins (ginsenosides). The American ginseng saponins separated and named were panaquilins A, B, C, D, E-l, E-2, E-3, G-l, G-2, (c) and (d). One-dimensional thin-layer chromatography did not completely separate panaquilin mixture and were subject to misinterpretation. The panaquilins were more accurately separated and identified by the two-dimensional thin-layer method established. Some differences in American ginseng saponins were dependent upon the plant age, time of collection, and part extracted. The American ginseng sapogenin components are panxadiol (panaquilins B and C), oleanolic acid (panaquilin D) and panaxatriol (panaquilin G-l). The panaquilins E-l, E-2 and E-3 mixture contains both panaxadiol and panaxatriol. The genins of panaquilins A, (c), (d) and G-2 were not identified. In addition, ${\beta}-sitosterol$ and stigmasterol were identified from the root ether extracts.

This paper examines how nation-specific history of Asian war brides affects different representations of war brides in Velina Hasu Houston's Tea (1984) and Julia Cho's The Architecture of Loss (2003). While war brides had long been excluded from American history, Japanese war brides were brought to public attention in the 1980s. Korean war brides, on the other hand, were kept out of sight until the 2000s. Focusing on how this time gap is related to ethnic difference, this paper analyzes dramaturgical differences between the two plays such as the presence/absence of war bride on stage or ethnic solidarity/familial reconciliation as the main device of war bride memorialization. Such differences, the paper suggests, stem from ethnic/historical differences between Korean and Japanese war brides. Through historical interpretations of the plays, this paper argues that America's military relationships with Korea and Japan were reproduced within the Asian-American families of each drama in ways that raise questions about pan-Asian identity.
