Traditional Korean medicine in the modernization process: institutional and attitudinal changes

The objective of the research is to contribute to the sociological understanding of East Asian medicine in Korea. Specifically, at the institutional level, this study describes changes in the structure and organization of the traditional East Asian medical system, looks for some major reasons for these changes, examines the system\u27s developmental process as a social system, and inquires about the system\u27s dynamic relationship with Western medicine. At the individual level, this research examines the Korean people\u27s attitudes and behaviors concerning East Asian medicine in relation to Western medicine; the effects of sociodemographic variables and nationalistic sentiment on attitudes and use of East Asian medicine are examined;From May to August of 1988, the data were gathered from 191 randomly selected residents of Bong-Dug 2 Dong in Taegu city, Korea. Observations of medical facilities and library research were also conducted in Korea;Along with general social changes, the East Asian medical system has been substantially modernized in recent years. Health policies have clearly affected the status of the traditional medical system. The influences of professionalization on the status of the traditional medical system are generally upheld. At the individual level, the popularity of East Asian medicine has been maintained among the people, regardless of their age, gender, level of education, rural residence experience, and income. Nationalistic sentiment is significantly related to the attitude scale of East Asian medicine but is not significantly related to the two behavior indexes. Attitudes and behaviors concerning East Asian medicine are significantly correlated, but the relationships are not as strong as was anticipated

An ultra-wideband transmit/receive module using 10 to 35 GHz six-channel microstrip multiplexers and its applications to phased-array antenna transceiver systems

This dissertation introduces new and simple techniques for suppression of multispurious passbands, which are inherent to the conventional microstrip parallel coupleline bandpass filters. In addition, the operation of harmonic suppression is analyzed using a simple model. Special emphasis is placed on the applications of several new filter designs for microstrip diplexers and multiplexers. Compact, full-duplex beam scanning antenna transceiver systems with extremely broad bandwidth have also been developed. Recent advances in broadband monolithic microwave integrated circuit (MMIC) amplifiers make the realization of extremely broadband phased-array transceiver systems possible. The ultra-wideband phased-array transceiver systems can be used in multi-band mobile satellite communication systems and wideband radars. This dissertation presents a multi-band, compact, full-duplex, beam scanning antenna transceiver system for satellite communications and two designs of ultra-wideband, low-cost radar systems as applications of the MMIC amplifiers. In addition, a multi-frequency antenna has been developed. A single-feed triple frequency microstrip patch antenna is presented as an answer to the recent demand for multi-function systems in the wireless communications. In summary, the research presented in this dissertation covers every component required to build an ultra-wideband, full-duplex beam scanning phased-array antenna transceiver. The work done in this dissertation should have many applications in the wireless communication systems and wideband radar technologies

Electronic topological transition in sliding bilayer graphene

We demonstrate theoretically that the topology of energy bands and Fermi surface in bilayer graphene undergoes a very sensitive transition when extremely tiny lateral interlayer shift occurs in arbitrary directions. The phenomenon originates from a generation of effective non-Abelian vector potential in Dirac Hamiltonian by the sliding motions. The characteristics of the transition such as pair annihilations of massless Dirac fermions are dictated by the sliding direction owing to a unique interplay between the effective non-Abelian gauge fields and Berry's phases associated with massless electrons. The transition manifests itself in various measurable quantities such as anomalous density of states, minimal conductivity, and distinct Landau level spectrum.Comment: title changed, an extended version for regular article format, 10 pages, 5 figure
