It is essential to determine a proper earthquake time history as a seismic load in a seismic design for a critical structure. In the code, a seismic load should satisfy a design response spectrum and include the characteristic of a target fault. The characteristic of a fault can be represented by a definition of a type of possible earthquake time history shape that occurred in a target fault. In this paper, the pseudo-basis function is proposed to be used to construct a specific type of earthquake, including the characteristic of a target fault. The pseudo-basis function is derived from analyzing the earthquake time history of specific fault harmonic wavelet transform. To show the feasibility of this method, the proposed method was applied to the faults causing the Gyeong-Ju ML5.8 and Pohang ML5.3 earthquakes.

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.

Systemic Functional linguistics considers Modality as the speaker’s attitude betwe en “yes” and “no”. Based on this, we discuss the Chinese modality system. First, we review what has been done on Chinese modals by the previous researchers. Then, we introduce Halliday’s modality system in English to establish a Chinese modality system and analyze the syntactic and semantic features of the typical modal verbs to point out the negotiation of Chinese modality.
