PBL Based Engineering Education to Cultivate Leadership Spirit in Postgraduate Students
Yokota Kazutaka,Maruoka Masatomo,Takaki Junji,Watanabe Shinichi 한국공학교육학회 2012 공학교육연구 Vol.15 No.5
Utsunomiya University started a 3-year project to develop an education program for postgraduate students to cultivate leadership spirits. The program is centered on a PBL in which each group of students is required to find an engineering or social problem themselves and start a project to solve the problem. Projects vary widely, from a straight product development to a summer program for children or local area development. Student groups are advised by senior engineers from industries. They give advice as to how a project should be managed and run, but will not give instructions. The PBL is compulsory for all students in the engineering master course students. The new education program also includes a series of lectures by engineers to show engineers’ job, activities, and career in the industry. Internship programs are also provided, in which students will be given opportunities to actively apply their knowledge and skills to real engineering tasks offered by the industry. The students are expected to gain something more than just experiences.

Trojan horse in an insect symbiosis

Many insects form mutualistic relationships with microbial symbionts, crucial for their physiological processes. The bean bug, Riptortus pedestris, establishes a unique gut symbiosis with the genus Caballeronia and consistently acquires these symbionts from surrounding soil with each generation. As a result, the bean bug unavoidably consumes a variety of environmental microbes, including potential pathogens. To address this, the bean bug has developed a specialized organ in its midgut that selectively filters out non-symbiotic microbes, thereby preventing contamination of its symbiotic organ. In this study, we identified a pathogenic strain from the genus Burkholderia that lethally affects the bean bug post-invasion of the symbiotic organ. This pathogen employs a strategy of mimicking the motility of native symbionts to infiltrate the symbiont sorting organ and displays a pronounced resistance against antimicrobial agents produced by the host. Upon establishing itself in the symbiotic organ, the pathogen breaches the midgut cells, leading to host mortality, and subsequently disperses into the external environment. Our findings unveil a cunning pathogenic tactic that exploits the mimicry of native symbionts within an insect's symbiotic framework.
