To enhance Bacillus thuringiensis (Bt) efficacy, four Cry toxins were purified from four different Bt strains and assessed in their combined efficacy. The Cry mixtures significantly expanded their target insect spectra. Bacterial culture broth of Xenorhabdus nematophila (Xn) significantly suppressed insect cellular immune response and increased Cry toxicity. The addition of Xn culture broth to Cry mixture significantly enhanced Bt efficacy in target insect spectrum and insecticidal activity.

This study investigated the possibility of reducing sodium and sugar intake in the Bulgogi bowl and yogurt, respectively, by utilizing food and non-food factors. Sodium and sugar replacers were the target food factors, and eating environment was the target non-food factor. The sodium content of Bulgogi bowls was reduced by 40%, and a flavor enhancer was applied to compensate for the reduced saltiness. Low calorie sweeteners, such as sucralose and stevia, were used to lower the sugar content of yogurt by 30%. Consumers were asked to evaluate the samples in one of the three eating environments: private booth evaluation, BOOTH; watching video clips during evaluation, VIDEO; conversation with friends during evaluation, FRIEND. The results showed that applying sodium or sugar replacers were effective in lowering sodium or sugar intake, respectively, without compromising the acceptance level of samples. Significant influences of the eating environment were observed on liking and perception of samples, but the influence patterns were not consistent between Bulgogi bowl and yogurt.

As a process for commercial application, production of reducing sugar, antioxidant, and DNA protective compounds from shrimp-shell powder was investigated in a fed-batch biodegradation using Bacillus cereus EW5. The fed-batch biodegradation was operated in a 5-L bioreactor for 96 h according to three times pulse-feeding strategy. On the basis of the equal working volume (3 L), the fed-batch biodegradation showed a better production of the target compounds than the batch biodegradation, with higher cell density and shortened biodegradation period. The maximum values of the target compounds were 0.297 mg/mL of reducing sugar, 92.35% DPPH radical scavenging activity, 98.16% ABTS radical scavenging activity, and 1.55 reducing power at $A_{700}$, which were approximately 12.1, 3.4, 5.2, and 8.4% enhanced, respectively, compared with those obtained from the batch biodegradation. The fed-batch culture supernatant also showed the enhanced DNA damage inhibition activity than the batch culture supernatant. As a result, the fed-batch biodegradation accompanied by high cell density could produce more useful compounds, enabling an increase in the reutilization value of shrimp-shell waste.

The objective of this study was to use cluster analysis to determine differences in eating-out behavior among grouped clusters of female consumers after each cluster was divided based on lifestyle patterns. The data were collected by interview survey from a biased sample of 1,300 females, ranging from ages 20 to 59, and living in residential districts of Seoul. Reliability analysis, factor analysis, cluster analysis, cross-tabulation analysis, and analysis of variance (ANOVA) were applied to the data. Four lifestyle factors were extracted by lower-division and classified as follows: health condition, consuming, food, and housing lifestyles. Based on these four factors, the female consumers were grouped as three clusters: the consuming-individuality type, rational-pursuit type, and conservative-stability type. The eating-out behavior of each cluster was significantly different in terms of frequency of eating-out, eating-out expenditures, restaurant selection criteria, food preferences, and the purpose for eating-out. Since this study surveyed females from ages 20 to 59, age and demographics were the differential factors in determining the various lifestyle types. Thus, to target the consumers who form a target market, the food industry should consider market segmentation that combines demographic factors such as age, income, and marital status.

In recent years, the relationship of language maintenance to culture and identity has received increased attention in the language acquisition and education fields. Korean immigrants in the U.S. form one of the biggest Asian groups and their language and cultural maintenance has been a major issue for both parents and ESL teachers. The present research is designed to investigate the cultural and social identities as well as the psychological investment factors that contribute to heritage language maintenance. Three Korean immigrant families in a small Midwest university town in the U.S. were surveyed and later interviewed. Issues and strategies concerning their children's Korean education in the U.S., coupled with the competing goal for the children to learn English were documented through parent interviews and interviews with school-aged focal children. Strategies and stances that facilitate or hinder both heritage and target language maintenance goals are presented along with participants' major reasons for heritage language maintenance in their homes and via Saturday schools. This work will assist ESL teachers and sociolinguists in situating both Korean student and parent goals in the context of shifting cultural and linguistic identities in countries where they have immigrated.

The polymerase chain reaction(PCR) of target lacZ and uidA genes were used to detect total coliform and Escherichia coli for determining water quality, respectively. Of 109 spring waters, coliform were detected from 38 spring waters by lacZ PCR method but 21 spring waters by culture method accepted by the Ministry of Environment for water quality monitoring. The lacz PCR method gave the results statistically equivalent to those of the culture method(kappa=0.62, McNemar=17.00). The uidA PCR method gave the same results to those of the culture method. The sensitivity and specificity of coliform and E. coli by PCR method were 100% and 80.7%, respectively. Therefore, PCR can be used for the rapid identification of Escherichia coli and coliform in potable water using uidA and lacZ.

This paper aims to analyze the influences of the socio-cultural environment on discourse in translation. To illustrate a deep connection between discourses and societies in which they were produced, communicative patterns of high- and low-context cultures are examined. Though the original version of the translated text comes from a different culture, the translation reflects communicative preferences of the target culture. To uncover some of these preferences, a comparative study of two translations from Russian into English and from English into Russian is conducted. This study, together with further investigation of some more recent translations into Russian, revealed a number of choices affected by translators' cultural background (for example, making the translation more emotionally charged) and current ideological preferences in the society (excessive use of anglicisms).
