This book addresses novel methods to treat a very popular disease, obstructive sleep apnea, based on a knowledge of an electrical engineering. Two approaches are given in the book using an upper-airway stimulation based on the pathogenesis of an obstructive sleep apnea. Implantable electronics are devised to control the tongue and the soft palate considering that they are the major pharyngeal muscles contributing to the apnea. First, for tongue control, a cuff electrode was designed and fabricated to stimulate the hypoglossal nerve, which innervates to the tongue muscle. Rare-earth magnets were embedded in the cuff for easy and repeatable installation of the electrode. For soft palate control, a palatal implant system was firstly developed to contract the soft palate muscle by applying electrical stimuli. Comprised of an implant, an intra-oral device, and an external controller, the palatal implant system is fully powered and controlled by means of wireless communication. The approaches were demonstrated in both in vitro and in vivo assessments, in collaboration with department of Otorhinolaryngology, Seoul National University Bundang Hospital.

Global Issues in Education bridges the discourse on globalization and education with international studies on race, class, gender, ethnicity, culture, and multiculturalism. The contributors to this volume address educational challenges of post-colonial Ghana, the United Arab Emirates, the Caribbean, China, and Germany juxtaposed against Western education in the United Kingdom and the United States. They synthesize macrosociology with educational research, which provides readers with the background, core knowledge, and global focus that is needed to understand international issues, as well as deal with diversity in the classroom. Global Issues in Education also addresses the need for additional research that makes the connections between the geopolitical economy and education, and it does this with a focus on the link to culture, ethnicity, and education.

Since its partition in the 1950s, the Korean peninsula has directly or indirectly shaped the broader security relations between regional powerhouses, and the recent test of a nuclear weapon by the North Korean regime has heightened tensions across the world. This study draws upon contributions from a diverse array of experts who offer their perspectives on the region's complex network of alliances and hostilities. The authors discuss the future of the region, the potential for military conflict and a new arms race, and the ways to maintain peace and stability. Since its partition in the 1950s, the Korean peninsula has directly or indirectly shaped the broader security relations between regional powerhouses, while the recent test of a nuclear weapon by the North Korean regime has heightened tensions across the world. Japan, feeling increasingly threatened by the North Korean regime and China's extravagant military expenditures, has begun questioning Article IX in its Constitution that renounces war and the maintenance of armed forces. Its neighbors, still haunted by Japanese atrocities during World War II, are fearful of a new nuclear arms race in the region. The United States, for its part, has adopted unprecedented hard-line policies in response to 9/11, going so far as to condemn North Korea as part of an axis of evil. It has strengthened its alliance with Japan and alienated its long-time strategic partner South Korea. Add to this the economic entanglements of each of these countries both with each other and with the rest of the world, and the regional security issues become even more paramount. This study makes sense of these complex alliances and frictions and offers an array of perspectives on the future of the region, the potential for military conflict and a new arms race, and the ways to maintain peace and stability. Topics include big power rivalries, South Korea's sunshine policy, anti-Americanism, and emerging nationalisms.
