본 연구에서는 지상공간이 부족한 대도시 밀집지역과 교통혼잡이 심각한 도심부의 교통문제를 해결하기 위해 안전성과 경제성이 확보되면서도 급속시공이 가능한 PSC 거더를 적용한 지하차도 급속시공 공법을 개발하였다. 그리고 이를 안정적으로 적용하기 위해 개발된 연결부 고정장치의 성능을 확인하기 위한 연구의 일환으로 캔틸레버 형식의 구조실험체를 통하여 성능 검증을 실시하였다. 본 실험은 고정연결장치의 방식과 가로보의 길이를 변수로 설정하였다. 실험결과, 개발된 고정연결장치는 형상과 연결방식에 상관없이 모두 안정적인 휨 거동을 나타내었다. 또한, 실험체는 파괴시까지 고정연결장치에 의해 연결된 PSC 거더와 상부 슬래브가 일체 거동을 하는 것으로 나타나 고정연결장치의 성능이 매우 우수한 것으로 확인되었다. 가로보의 길이에 따른 영향은 가로보의 길이가 길어짐에 따라 구조물의 성능이 향상되는 것을 확인할 수 있었다. In this study, a safe, economic, and rapid construction method of underground roadway using PSC girder is developed to reduce traffic congestion and maximize space usage in urban area. For an efficient application of the method, a rigid joint connection is proposed and tested. For the testing, cantilever specimens were used to verify its capacity. The parameters for this study were cross beam length and joint connection type. The results of the test showed that the proposed connection system has superior performances. Despite having differences of cross beam length and joint connection type, the stable flexural behavior was shown in all of the tested specimens. Also, the behaviors of PSC girders and upper slabs connected by the proposed method showed superior performance. Moreover, the improvement of structure performance according to the increase of length of cross beams has been verified.

본 연구에서는 합성보의 특징을 활용하고, 일부 고강도강 적용이 가능한 단면을 개발하여 이에 대한 기초연구를 실시하였다. 본 논문은 그 첫 번째로 단위부재인 합성보의 휨성능을 실험을 통해 평가하였다. 실험결과를 통해 기존 합성보의 공칭강도 산정식 적용여부를 검토하였고, 각 구성부재를 주요변수로 하여 실험하였다. 실험결과 신형상 U형 합성보의 내력평가는 콘크리트 압축강도와 강재의 인장강도에 의한 우력모멘트로 소요모멘트에 저항하는 것으로 평가하는 것이 적합하며, 보 춤 및 강판 두께에 비례하여 내력이 안정적으로 증가하였으며, 연성거동을 하는 것으로 나타났다. In this research, we carry this study into effect on the basis of utilizing character of composite beam and developing applicable section to some of high strength steel. We evaluated flexural capacity of composite beam that is a unit member through experiments. The existing nominal strength formula of Composite Beam which is a previous method was reviewed and the experiment had been progressive by using each composite members as main variables though the result. Capacity evaluation of U-shape Hybrid Forming Beam(HyFo Beam) which is a new shape show as follow from the result. First, it is resonable to resist demand moment by couple moments which are occurred in concrete compressive-strength and steel tensile-strength. Second, the capacity was stably increased in proportion to the depth of beams and the thickness of steel plates. The last, HyFo Beam was showed as ductile behavior.

Optimization of Culture Medium forRifamycin SV Production by Amycolatopsis mediterranei MM2 Using Statistical Designs

김성배,Hae Joong Shin,Chang-Joon Kim 한국생물공학회 2007 Biotechnology and Bioprocess Engineering Vol.12 No.4

In this paper, we conducted a statistical optimization of the medium components for the production of rifamycin SV by Amycolatopsis mediterranei MM2. In order to maximize the yield of rifamycin SV, a Plakett-Burman experimental design (PBD) was initially utilized in the screening of the medium components among 11 nutrients. Glycerol and yeast extract were determined to influence significantly the yield of rifamycin SV. Then, a central-composite experimental design (CCD) was utilized in order to optimize the concentrations of the screened components accqired using the PBD and to predict the mutual interactions occurring between the screened components. The predicted optimal glycerol and yeast extract concentrations were determined to be 43.8 and 9.5 g/L, respectively. At this optimum point, the predicted rifamycin SV yield was 490.5 mg/L, whereas the corresponding experimental yield was 480.3 ± 43.8 mg/L.

This is the study on causes and remedies of hearing disturbance in chinese medical journals(1991-1993). The results were as follows. 1. The causes of sudden deafness(突發性耳聾) were usually fire in the liver(肝火).phlegmatic fire(痰火), deficiency of the vital function and essence of the kidney(腎虛), blood stasis or sludge due to stagnation of vital energy stagnation(氣滯血瘀). Remove endogenous heat or fire method(淸瀉火熱法). circulation of phlegm and dampness(運化痰濕). using tonics to cure disease due to deficiency of vital essence of both the liver and the kidney(滋補肝腎) were used for each treatment. 2.The causes of menieres disease were usually mental disturbance due to phlegmatit fire(痰化上搖). dampness-phlegm long standing(痰濕內停), water-dampness retention(水濕停滯), Method of remove heat and circulation phlegm(淸熱化痰法), method of remove water and dampness(利水渗濕法), invigorate function of the spleen and circulation of dampness method(健脾化濕法) were used for each treatment. 3. The causes of toxico-deafness(中毒性 耳聾) were usually heart, liver and kidney functional weakness(心肝腎虛), vital essence and blood weakness(氣血虛弱). Remove obstruction in the flow and circulation phlegm(通窮化痰), reinforce vital energy and tonify blood (補氣活血), using tonics to cure disease due to deficiency of vital essence of both the liver and the kidney(滋補肝腎) were used for each treatment. 4. The causes of deafness (耳聾), tinitus(耳鳴) were usually mental disturbance due to wind and heat(風熱上搖). flaming up of excessive heat of the liver(肝火上亢). exhaustion seat of reproductive essence in kidney(腎精虧虛). Remove endogenous heat and disperse wind(淸熱疏風). remove the fire of liver(淸肝瀉火), through nourish kidney check exuberance of yang(滋腎潛陽), nourish kidney yang(補腎陽). replenish vital energy and improve essential substance(益精血), blood activate for treatment of blood stasis(活血化瘀) were used for each treatment. 5. The effects of mainly used drugs were classified into method of water and dampness remove medicine(利水渗濕藥), nourishing liver and kidney medicine(補肝腎藥), improve blood and vital energy activate medicine(活血行氣藥), through nourish yan medicine check exuberance of yang(滋陰潛陽藥).

The Effects of Nonionic Surfactants on the Pretreatment and Enzymatic Hydrolysis of Recycled Newspaper

김성배,Hyun Joo Kim,Chang Joon Kim 한국생물공학회 2007 Biotechnology and Bioprocess Engineering Vol.12 No.2

The effects of surfactants on the pretreatment and enzymatic hydrolysis stages of recycled newspaper processing were examined. Newspaper substrate was pretreated with surfactants at 40℃ and 400 rpm for 1 h, and the enzymatic digestibilities of the pretreated substrate were compared. NP-20 was 10~20% more effective as a surfactant than Tween-20 and Tween-80. To investigate the effects of the surfactants on the subsequent enzymatic hydrolysis stage, the newspaper was pretreated with NP-20 and then hydrolyzed in the presence of TW-20 or TW-80. TW-80 showed an approximate 7% higher digestibility than TW-20. The surfactant effect on the hydrolysis of the untreated newspaper was significant, whereas the surfactant effect on the hydrolysis of the surfactant-pretreated newspaper was marginal. When the digestibilities of the pure cellulose substrates (α-cellulose and filter paper) were examined, markedly different surfactant effects were observed. In contrast to the newspaper substrate, the surfactant-pretreated pure cellulose substrates had a significant effect on digestibility when they were hydrolyzed in the presence of a surfactant, indicating that the surfactant effect on digestibility is highly dependent on substrate type.
