The purpose of this study was to examine how exterior-relieving herbs are blended by each prescription with emphasis on Internal disease range of Donguibogam by limiting Wind herbs in exterior-relieving herbs to apply exterior-relieving herbs to internal diseases. Prescriptions mixed with exterior-relieving herbs is a prescription adding Bojungikgitang, Yijintang, Yimyosan, Yukilsan and Gilgyeongjigaktang. The mixed exterior-relieving herbs were diversely operated according to each prescription or medicines. However, the mixed exterior relieving herbs were mixed for rising yang & tonifying qi(升陽益氣) for the most part. The exterior-relieving herbs mixed with prescriptions had the total 15 kinds, Bupleuri Radix, Cimicifugae Rhizoma among them were mixed with prescriptions for the most part. In addition, two-kind mixed exterior-relieving herbs were utilized in order of Bupleuri Radix Cimicifuga Rhizoma and Bupleuri Radix Cimicifugae Rhizoma Notopterygii Rhizoma Ledebouriellae Radix. Taken together, Wind herbs is applied several purpose, so that it can contribute to treatment and prevention of internal diseases in present-day.

High-rising buildings are a sort of solution to recent cities. Till now real estate development was concentrated in new development on vacant lots, and it resulted urban sprawl. Generally large cities are confronted with the exodus of industry and population from city. High-rising buildings solve many problems associated with this problem. The purpose of this research is to identify the effect of super high-rise mixed use building project process on apartment price. For this study, the hypothesis is that price of apartments is influenced by project process of super high-rise mixed use building. The study concerned 4 variations of project process that is building permits stage, sale stage, construction starting stage and stage of moving into building. The target projects of buildings are selected by number of floor(over 40 floors) and construction time. And 48 apartment complex are selected around super high-rise mixed use building. This study uses hedonic price function to analysis effect of project process of super high-rise mixed use building. A price of apartments is defined as a dependent variable. Characteristics of residence, complex, district and super high-rise building are defined as independent variables. The results are as follows; first, there is no error in price model of this study. Second, it is found that apartment price was influenced negatively by building permit stage and sale stage of super high-rise mixed use building. But that was influenced positively by construction starting stage and stage of moving into building of that. Third, as the project process of super high-rise mixed use building was proceeded, price of apartments was increased.

Ready-mixed shotcrete mixed with high quality materials and can be controled shotcrete quality is producted in plants and transported to construction fields, so do not need a field batch plant. In this study, the field construction system that can be applied Ready-mixed Shotcrete to construction fields was proposed, and the all-in-one silo that was the key component of the field construction system was design. It was performed to evaluate the constructability that the field construction process analysis in case of applying a field batch plant and the all-in-one silo, the cost analysis of the material production and transport in a road tunnel was also performed to evaluate the economic feasibility of Ready-mixed shotcret.

This study used EPR's sheet and cable as a specimen, and measured residual voltage depending on the induced voltage, thickness of the sheet, and shape of the sheet and cable. The results of the study lead to the following conclusion: 1) The residual voltage increased in proportion to the induced voltage as time increases; 2) The residual voltage of the basic mixed specimen and practical mixed specimen increased as time increased; 3) The peak of the cable appeared earlier than that of the sheet in both of the basic mixed specimen and practical mixed specimen.

In this study, retardation behavior of fatigue crack under single overloading of the mixed mode I+II state was experimentally investigated. To produce single overload in the mixed mode I+II state, the compact tension shear (CTS) specimen and loading device were used. The propagation tests for fatigue crack were performed under mode I loading overloading afterwards. We examined the observed deformation aspects, variation of fatigue life and crack propagation rate, and the aspects of retardation behavior from tests. The retardation effect of mixed-mode single overload on fatigue crack propagation behavior was smaller than that of mode I single overload. It has been confirmed that the retardation behavior did not immediately appear and the retardation length was short when the component of mixed-mode overload was changed.

Concrete track will be constructed in Gyungbu High Speed Railway II(GHSR II) stage construction site from Daegu to Busan. Concrete track is supported by substructure consisting of the original ground and embankment and does not allow the settlement of track because of its structural type. The embankment is composed of rock and soil mixture and settlement is feasible. So management of settlement of embankment is key point in successful construction of the concrete track. Compaction management of mixed fill materials is important in minimizing the settlement of embankment. In this study, in order to assess the compaction characteristics of mixed fill materials, large laboratory compaction tests were conducted. Mixed fill materials were obtained from two construction sites in GHSR II construction site. Modeled mixed fill materials having different rock type, fine content, maximum particle diameter, and moisture contents were prepared. From the test results, compaction characteristics of mixed fill materials were analysed.

The purposes of this study were (a) to compare the level of sense of community and community activity of the mixed-use residential buildings' residents with the expected residents for the mixed-use residential building, (b) and to investigate the degree of their needs of social interaction. For the survey the questionnaire from 176 residents of mixes-use residential building in Seoul, and 67 expected residents in Bundang Newtown are used. The analytical methods adopted in this study were frequency, percentage, chi-square test and t-test. It was found that the level of sense of community and the community activities of the mixed-use residential building' residents were higher than those of the expected residents. Their residents reported higher degree of participation on community activities than the expected residents. It was also found that the common space in their residential area promoted the residents' sense of community and community activity.

Hydrox gas which is the mixed gas of hydrogen and oxygen gained fromwater electrolysis is one of the new clean energy sources and thus is researched and commercialized actively. Especially, it can be replaced the fossil energy and shows the better quality compared to the conventional energy such as LPG or acetylene gas. The mixed gas of hydrogen and oxygen is gained from water electrolysis reaction. It has constant volume ratio 2:1 of hydrogen and oxygen, and it is used as a source of thermal energy by combustion reaction. Further, hydrox gas is nearly a mixed ideal gas combusting itself completely and its combustion shows anunique characteristics of implosion. In this study, temperature rise effects on hydrox gas content through mixed combustion test of kerosene and hydrox gas and LPG and hydrox gas are investigated. it is also confirmed that economy of mixed combustion of hydrox gas as effective energy is fairly probable.

Mixed-model production lines are often used in manufacturing systems. In production lines, different product types are simultaneously manufactured by processing small batches. This paper describes a new welding assembly technology involving the development of experimental models for a mixed-model production line in an automobile company. Due to the extensive number of models, the design of a welding assembly system is complicated. Performance evaluation is an important phase in the design of welding assembly lines in a mixed-model production environment. In this study, a new welding assembly technology for a mixed-model production method was used to weld the package tray and dash panel of a vehicle.
