The 18th GEL-SIT plenary seminar was held. At this seminar, eight undergraduate students (B4 students) reported on the progress of their graduation research projects. So far, the B4 students have gained experience in giving presentations and have become able to effectively highlight key points in their reports and present the progress of their research in a clear and concise manner. Each of the eight B4 students is working on a different research topic, and in previous years at this time there would typically be some variation in progress among them. This year, however, all of the B4 students have made remarkable progress. As they enter this crucial stage of their thesis research, I hope they will remain patient, maintain confidence in their work, and enjoy the process as they continue to make progress.
