  • According to the trend for electric power equipment of high capacity and reduction of its size, the needs for the new high performance electric equipments become more and more important. On of the possible solution is high temperature superconducting (HTS) power application. Following the successful development of practical HTS wires, there have been renewed activities in developing superconducting power equipment. HTS equipments have to be operated in a coolant such as liquid nitrogen ($LN_2$) or cooled by conduction-cooling method such as using Gifford-McMahon (G-M) cryocooler to maintain the temperature below critical level. In this paper, the dielectric strength of some insulating materials, such as unfilled epoxy, filled epoxy, and polyimide in $LN_2$ was analyzed. Epoxy is a good insulating material but fragile at cryogenic temperature. The filled epoxy composite not only compensates for this fragile property but enhances its dielectric strength.

  • The main function of the general hospital building is to provide medical facilities and service. However, damage to the non-structural elements such as architectural, medical, mechanical and other components will interrupt those functions after the earthquake. Especially, it is considered that, damage to the non-structural elements is a serious event because it is directly associated with the lives of patients. Therefore, this study evaluated whether the certain non-structural elements of general hospital building has the seismic performance to provide hospital medical services after the earthquake. The evaluation is conducted by selecting the non-structural elements used in general hospital which are sensitive to acceleration, such as cooling towers, air handler, MRI and CT. As a result, the non-structural elements located on the upper floor without suitable support method did not meet the performance objective. Therefore, adequate anchorage against the seismic event is required for such non-structural elements that are acceleration-sensitives.

  • This article discusses accomplishments and historical implications of American missionary dentist W.J. Scheifley and the first Korean dental department, which was established in 1915 in Korea. W.J. Scheifley, with Christian service mind and mission as a dentist, applied to American Protestantic missionary dentist overseas. The dental department in the Severance Union Medical College introduced the scientistic dental education of America, facilitated research on the dental condition of the Korean people, and ran independent dental clinic. W.J. Schiefley criticised the profit-seeking attitude of Japanese dentists and denturist(="IPCHISA", in Korean pronunciation) and emphasized on the significance of Oral Health. He did all kind of dental treatments with advanced equipments like X-ray machine, and managed the collective oral health care for missionaries overseas. He trained medical students and assistants of the dentists with the goal of producing Korean dentists, but he failed due to the Dentist law introduced by Japanese colonial administration that interfered with producing Korean dentists. However, O.R. Avison's proposal of the establishment of dental schools stimulated the establishment of Kyungsung dental school, which provided the basis for the Dental department in the Severance Union Medical College becoming special training institution for Korean Dentists.
