        This study explores the notion of ‘good language teacher’ (GLT) identity in the context of English education in South Korea. While other studies have investigated parents’ and general public preferences for and associations of good language teacher identity with ‘native-speaking’ teachers of English, little research has examined the views of young learners as to what constitutes a GLT. In this study, a survey tool was used to collect student images and descriptions of imagined, good English teachers. A total of 577 young Korean students (K-6th grade) provided their own images and descriptions of good English teachers, both in English and Korean. The findings indicate that student perceptions of GLT identity strongly reflects their immediate learning experience. Contrary to previous studies showing preference for teachers according to ‘native speaker’ or other markers (e.g., race, gender), the study demonstrated no strong preference for native speaking teachers. Instead, factors such as personality were emphasized. This study provides implications for recruiting and hiring practices for English teachers.

        The master sintering curve (MSC) is derived from densification data over a range of heating rates and temperatures. To improve the accuracy, several modifications were proposed: multi-phase MSC for solid state sintering with phase changes, MSC for liquid phase sintering, and MSC with consideration of grain growth. The developed MSC models were applied to several material systems such as molybdenum, stainless steels, and tungsten heavy alloys (WHA), in order to evaluate the effect of compaction pressure, phase change, grain growth, and composition on densification, to classify regions having different sintering mechanism, and to help engineer design, optimize, and monitor sintering cycles.
