The purpose of this study was to explore how college students perceived multiliteracy experiences through the intercultural exchange project in an online EFL class. This study explored students' perceptions of the communication experiences with partners from different cultures and their intercultural understanding. Two types of data were collected from 30 Korean college students: qualitative data including activity reports, reflection notes, and final tasks; quantitative data including the responses to the perception questionnaire and intercultural sensitivity survey. Results of statistical analyses did not reveal significant differences in paired t-tests for cultural sensitivity. However, data showed that students experienced meaningful practice of multiliteracy and intercultural understanding. Students experienced four dimensions of the pedagogy of multiliteracy and improved their cultural sensitivity. Researchers suggest that EFL teachers find ways for learners to become multiliterate communicators with learning experiences of multiliteracy in English classes.

This study investigated the use of L1(English) by L2(Korean) learners’ interaction with their native-speaking conversation partners from a sociocultural perspective, using the lens of conversation analysis. The data included 64 hours of recorded interactions of 16 conversation pairs of nonnative learners of Korean and their native conversation partners as well as learners’ diary entries. Findings gleaned from qualitative analysis of learners’ use of their L1 (i.e., English) during native-nonnative pair interactions outside the classroom showed that the overall use of L1 by L2 learners found to be facilitative of their L2 learning. The results proposed a model of L2 learners interaction with their conversation partners that attempted to link learner’s use of L1 and their L2 proficiency, and concluded that learners’ interactions played a key role in improving L2 learners’ language proficiency. In addition, pedagogical recommendations based on the research findings were proposed.

Mercuric chloride, inorganic compound, is one of the most important drugs that has been used in the field of argriculture, antisyphilitica and anticeptics, but it is not used clinically at present. We have studied the effect of testosterone on the mercuric chlorideinduced nephrotoxicity. Renal lipid peroxide concentration of male rat treated with mercuric chloride was significantly increased in comparison with that of the female rat, it showed similar effects on testosterone pretreatment. Changes in renal catalase and glutathione peroxidase activities were not siginificantly different in testosterone-treated groups. But, renal xanthine oxidase and aldehyde oxidase activities of testrosterone-treated group given mercuric chloride significantly increased in comparison with that of the testosterone-treated alone. Animals treated with testosterone prior to mercuric chloride showed more severe damage on histological observations than those treated with testosterone only. Consequently, we suggest that the mercuric chloride-induced nephrotoxicity might be renal lipid peroxide generating enzyme system by testosterone.
