The purpose of this study is to design a Japanese language class based on the analysis of college students’ assignments and their misuses of ‘can’ expressions in them during a Japanese conversation class. In the class, the assignments required the students to record their thoughts about conversation topics. For the assignments, the instructor tried to transcribe the students’ recordings, find their misuses of ‘can’ expressions and provide some corrective feedback for the misuses. Following the feedback, the students were asked to resubmit their recordings and then, the instructor examined their recordings again focusing on ‘can’ expressions. The findings from the students’ first recordings revealed that the students used some verbs that describe ‘possibility’ at first, and gradually they used more ‘surukotogadekiru(=can)’ expressions. Then, finally, the students tended to use both ‘possibility’ verbs and ‘surukotogadekiru(=can)’ expressions regardless of the students’ proficiency levels. However, by comparing to the students’ second recordings, the use of ‘possibility’ verbs increased while the use of ‘surukotogadekiru(=can)’ expressions decreased in the second recordings. Based on the findings, a class design that can be applicable to the Japanese language conversation classes was suggested.

Phospholipase C (PLC)는 다양한 세포주에서 세포내 신호전달에 중요한 역할을 한다고 알려져 있으나, 생쥐 난자성숙 과정과 착성전 배아발생 과정에서 PLC의 역할과 발현은 아직 연구된 바 없다. 본 연구에서는 난자성숙과 착상전 배아발생 과정에서 생쥐의 PLC β1과 γ1의 유전자 발현을 조사하기 위하여 한 개의 난자 혹은 배아에서 추출된 total RNA를 사용하여 경쟁적 RT-PCR 방법으로 mRNA를 정량하였다. PL
