In this study, performance based seismic design was performed on the shear wall structural system and the beam-column system as a variable general rebar and seismic rebar, and comparing the capacity of the two models of each system. From nonlinear analyses, the capacity of the shear wall structural system applying seismic rebar has shown a stable behavior after the maximum strength, but there is little difference. Furthermore, both models showed similar capacity between story drift and story shear force and capacity of members. These results are attributed to the fact that the seismic rebar, which is highly ductile under the seismic load applied to the target structure, does not render sufficient capacity.

At present, the problem to secure seismic resistance capacity is one of the most important issue in school buildings. However, the range of facilities to consider retrofit or the proper direction of seismic retrofit haven't provided in details. Therefore in this study, a series of school buildings were chosen as established time, and the structure composition and the seismic performance of the school buildings were investigated to get the comprehensive features of seismic resistance capacity in school buildings. At result, it was presented that the member capacities were less than criteria and structure system was showed the brittle behavior at the collapse prevention level at the school buildings before 1990 year. At the school buildings after 1990 year, though it is hard to get general features for various compositions, it was presented that they have problems for seismic performance evaluation in some buildings at life safety level, specially in the direction of X axis. So, considering the introduction process of seismic criteria in Korea, the school buildings before 2005 year should be examined for seismic resistance capacity and the seismic performance should be examined as well as member capacity to resist seismic.

Precast Concrete (PC) construction method can be the one that is suitable for long-life housing due to its merit in respect of maintenance and durability based on crack-free from mass production with indirect construction cost-saving-effect due to shortening construction period comparing to the conventional construction method, but it has the problem that causes the raise of direction construction costs. So, this study analyzed its economic feasibility of PC method whose maintenance and durability are excellent for underground parking lot of apartment house for accomplishing cost-saving long-life housing by applying the various structural system. In evaluation of unit module structural system, two-way PC system requires 10 to 28% more costs for frame work than RC rigid frames, and, one-way PC system 98~112%. Although it varies depending on the method, the costs are similar to RC rigid frame structure, provided a proper method is adopted. Also, Model 11, which was most economical in the evaluation, was applied to an real parking lot and about 2 to 6% of construction costs was reduced than RC rigid frames. This seems to be because, although PC system has a higher production cost, introduction of P.S (prestress) reduces member depth and, therefore, height, as well as the number of members per unit module.

For application to apartment house, which accounts for the vast majority of constructions in domestic, various studies on development of device for seismic control are being conducted by private constructors and public companies. Also, a device of lintel beam type has been developed based on structural characteristics of apartment houses and risk of earthquake in domestic, and applied to newly constructed apartment houses. Currently, in domestic, research on efficient installation method of device for seismic control is rare, as it is still in the early stage. Therefore, in this study, based on the damper for lintel beam that was recently developed, an installation method for efficient damper for lintel beam will be proposed according to installation capacity and horizontal position of dampers of different heights.

The objective of this paper is to suggest structural design for the long-life housing apartment complex to save the construction cost. The key is to use unavailable underground space due to bearing walls or bad configuration of columns in apartments as the parking space. Therefore, the structural plan of apartment buildings considering the parking section in the underground should be designed. After analytical resutls of three cases, it is significant effect in saving construction cost.

본 연구에서는 야생 효모 Saccharomyces cerevisiae Y28을 이용하여 참다래-대봉감 혼합과실주 제조를 위해 과즙의 효소 처리 조건 확립, 참다래-대봉감 비율별 알코올 발효 특성 및 향기성분 분석을 조사하였다. 최적 효소 처리 조건은 참다래는 0.3%, 1시간이었고 대봉감은 0.3%, 3시간이었다. 참다래-대봉감 혼합과실주의 pH는 발효 후 3.69-3.77로 거의 변화가 없었고, 산도는 발효 후 증가하여 1.51-2.07%로 있었으나, 대봉감 첨가량이 증가할수록 산도는 낮았다. Brix 및 환원당은 발효 후 감소하여 각각 $8.8-9.6^{\circ}brix$ 및 6.07-6.90 g/L 있었다. 혼합과일주의 주요 유기산은 tartaric acid, malic acid 및 citric acid 있었고, 유리당 sucrose 및 glucose은 미량 검출되었다. 발효 후 수용성 phenolics 함량 감소하고 상대적으로 갈변도는 증가하여 각각 1.00-1.25 g/L 및 0.212-0.412 수준이었다. 주요 향기성분으로 ethyl acetate와 hydrazine, 1,1-dimethyl가 있으며 장미와 유사한 향을 가지는 phenylethyl alcohol 또한 모든 시료에서 검출되었다. 관능평가 결과, 참다래:대봉감(7:3) 혼합과실주가 다른 비율 혼합과실주보다는 기호성이 약간 우수하였다. The study was aimed to investigate the mixing ratio of kiwi and persimmon juices for the production of good quality wine by Saccharomyces cerevisiae Y28. Firstly, the optimum condition of rapidase treatment for the kiwi and persimmon juices was established, thereafter various mixing ratio (10:0, 9:1, 8:2, 7:3, 6:4, 5:5) of kiwi and persimmon was investigated regarding physiochemical properties and flavor compounds of wine. As the result, the optimum conditions were obtained as 0.3% rapidase for 1 h in kiwi and 0.3% rapidase for 3 h in persimmon. According to higher ration of persimmon, the pH of wines increased from 3.69 to 3.77, while the acidity of wines decreased from 2.07% to 1.51% at 14 days fermentation. The ranges of brix and reducing sugar in wines were decreased which ranges around 9.6 to 8.8 and 6.07 to 6.90 g/L, respectively, after fermentation. Major organic acid in wines were identified as tartaric acid, malic acid, and citric acid. A small amount of free sugar such as sucrose and glucose were detected in wines, but fructose was completely absent. The soluble phenolic contents were decreased that ranges around 1.00 to 1.25 g/L, in contrast, browning degree were increased ranges around 0.212 to 0.412 after fermentation. The major flavor components were identified as ethyl acetate and hydrazine, and 1,1-dimethyl. Importantly, phenylethyl alcohol was detected from the all wines that have a typical rose like flavor. But sensory test results and preference of kiwi-persimmon (7:3) mixing wine was better than the other wines.
