Recently, an unprecedented emerging infectious disease has rapidly spread, causing a global shortage of wards. Although various temporary beds have appeared, the supply of wards specializing in infectious diseases is required. Negative pressure isolation wards should maintain their function even after an earthquake. However, the current seismic design standards do not guarantee the negative pressure isolation wards’ operational (OP) performance level. For this reason, some are not included in the design target even though they are non-structural elements that require seismic design. Also, the details of non-structural elements are usually determined during the construction phase. It is often necessary to complete the stability review and reinforcement design for non-structural elements within a short period. Against this background, enhanced performance objectives were set to guarantee the OP non-structural performance level, and a computerized tool was developed to quickly perform the seismic design of non-structural elements in the negative pressure isolation wards. This study created a spreadsheet-based computer tool that reflects the components, installation spacing, and design procedures of non-structural elements. Seismic performance review and design of the example non-structural elements were conducted using the computerized tool. The strength of some components was not sufficient, and it was reinforced. As a result, the time and effort required for strength evaluation, displacement evaluation, and reinforcement design were reduced through computerized tools.
Choryang-weagwan which was the largest international trading place between Joseon Dynasty and Tokugawa Shogunate had been maintained from 1678 through 1872 in Busan. Particularly, they had 21 times repairing constructions for 200 years since its establishment. It is noticeable that Joseon Dynasty permitted Tokukawa Shogunate to construct main pavilions and guesthouses as his style due to the good-neighbor policy between two countries, and Tokukawa Shogunate struggled to achieve his own culture in that place under the supervision of Joseon Dynasty For satisfying his needs, the architectural craftsmen of Tokukawa Shogunate were mobilized by the chief of construction company which was called kumi-gasira in the most of cases. When they came to Busan for the construction, they brought their own architectural tools. On the one hand, the carpenters and workers of Joseon Dynasty were organized by the traditional construction superintendents which were called Gamdong-gwan and they had to carry out their responsibilities with Japanese technicians at the same workplace. Judging from this fact, the construction site of Weagwan was the good place for exchanging the architectural technology between two countries. This study especially focuses on Tokukawa Shogunate craftsmen who made the repairs of Dongwan-samdaechung in 1727 such as carpenters(Dai-ku), sawyers(ko-biki), and surveyors(Tsue-tsuki) and their tools such as Hatsuri(=Masakari) and Yo-ki(=Oh-no). The constructions in this period, there were not only the repairs of 3 major pavilions including the trading center, but also one of the most active repairing constructions comparing with other period, therefor these were important constructions to shows us repairing construction of Choryang-weagwan of those days.
History of architecture technology is the area where further studies are the most needed in Korean architecture history. This present study deals with architectural tools and woodworking of Baekje as a first step in exploration of Korean architecture technology history especially, that of Baekje dynasty. Based on the study of real artifacts and archeological sites showing the trace of tool use, function and forms of architectural tools were classified, characteristics of tools investigated, and woodworking technology analyzed. The main tools of analysis include Square, Black Inkpot, Hatchet, Saw, Chisel, Wood Hammer, Axe, and Plane. It is assumed that architectural technology during Baekje dynasty might have leapt into the new stage thanks to the regular use of iron tools. Compared to those of previous eras, iron tools of Baekje are more elaboratedly-designed and well-defined in function. In addition, wooden architectural tools from Baekje demonstrate the superiority of its woodworking technology Historical record also shows the fact that craftsman from Baekje participated in construction of temples of Shilla and Japan. Precise assessment of Baeje architecture technology is difficult because no Baekje wooden architecture is still remaining. The facts mentioned above, however, surely prove the excellence of architecture technology of Baekje.
