Stress in medical education has been inevitable among medical students. The prevalence of mental health problems among medical students is increasing, requiring a reliable tool for accessing assessments. The General Health Questionnaire (GHQ-12), designed to screen for mental disorders and psychological stress, is a promising tool. Although the factor structure of GHQ-12 has been studied internationally, it is still unclear in Vietnam.

The need for operating circuits at increasingly higher speeds has always challenged designers. From radar and television systems in the 1940s to gigahertz microprocessors today, the demand for pushing circuits to higher frequencies has required a solid understanding of their speed limitations. In this chapter, we study the effects that limit the speed of transistors and circuits, identifying topologies that better lend themselves to high-frequency operation.
