Bamboo is an evergreen perennial plant, and it is known as one of the most productive and fastest-growing plants in the world. It grows quickly in moderate climates with only moderate water and fertilizer. Traditionally in Asia, bamboo is used for building materials, as a food source, and as versatile raw materials. Bamboo as a biomass feedstock can be transformed to prepare activated carbon using the thermal treatment of pyrolysis. The effect of process variables such as carbonization temperature, activation temperature, activation time, the amount of steam, and the mixing ratio of phosphoric acid and bamboo were systematically investigated to optimize the preparation conditions. Steam activation was proceeded after carbonization with a vapor flow rate of $0.8{\sim}1.8mL-H_2O\;g-char^{-1}\;h^{-1}$ and activation time of 1 ~ 3 h at $700{\sim}900^{\circ}C$. Carbon yield and surface area reached 2.04 ~ 20.59 wt% and $499.17{\sim}1074.04m^2\;g^{-1}$, respectively, with a steam flow rate of $1.4mL-H_2O\;g-char^{-1}\;h^{-1}$ for 2 h. Also, the carbon yield and surface area were 24.67 wt% and $1389.59m^2\;g^{-1}$, respectively, when the bamboo and phosphoric acid were mixed in a 1:1 weight ratio ($700^{\circ}C$, 2 h, $1.4mL-H_2O\;g-char^{-1}\;h^{-1}$). The adsorption of methylene blue into the bamboo activated carbon was studied based on pseudo first order and second order kinetics models. The adsorption kinetics were found to follow the pseudo second order model, which is governed by chemisorption. 대나무는 지구상에 존재하는 식물 중 적절한 기후와 토양조건에서 생산성이 가장 높고, 성장속도가 가장 빠른 다년생 식물로 알려져 있다. 전통적으로 아시아에서 대나무는 음식, 건축 및 다양한 재료로 활용되고 있다. 바이오매스 자원으로 대나무는 열분해과정을 거쳐 활성탄으로 제조될 수 있다. 본 연구에서는 탄화온도, 활성화 온도, 시간, 수증기의 양, 그리고 인산의 양 등을 변화에 따른 최적의 대나무 활성탄 제조 연구를 수행하였다. 대나무 탄화 후 수증기 활성화를 위해 $700{\sim}900^{\circ}C$의 온도, $0.8{\sim}1.8mL-H_2O\;g-char^{-1}\;h^{-1}$ 수증기 유량 범위에서 1 ~ 3 h 동안 활성화를 진행하였다. 수증기 유량을 $1.4mL-H_2O\;g-char^{-1}\;h^{-1}$으로 2 h 동안 실험한 결과 활성탄 수율과 비표면적은 각각 2.04 ~ 20.59 wt%, $499.17{\sim}1074.04m^2\;g^{-1}$의 값이 나왔다. 대나무와 인산의 질량비를 1:1로 혼합한 후 $700^{\circ}C$에서 유량 $1.4mL-H_2O\;g-char^{-1}\;h^{-1}$ 속도로 2 h 동안 활성화를 진행한 결과 활성탄 수율과 비표면적은 각각 24.67 wt%, $1389.59m^2\;g^{-1}$의 값이 나타냈다. 제조된 대나무 활성탄을 대상으로 메틸렌블루 흡착 실험을 통해 유사 1차, 2차 속도식 모델을 적용하였으며, 화학적 흡착을 의미하는 유사 2차 속도식에 따랐다.

We investigated the effect of ammonium chloride, which is known to affect lysosome-mediated viral internalization, on the infectious of fish cells, CHSE-214, with Infectious Pancreatic Necrosis Virus (IPNV). Progeny production of IPNV was delayed 6 to 8 hours in IPNV infected CHSE-214 cells by the addition of NH₄C1 at the final concentration of 20 mM. The multiplication of IPNV, however, was no longer inhibited when NH₄C1 was present only for the first 4 hours after viral infection. Thus the inhibitory effect of NH₄C1 seems to be on some other steps but internalization. For the inhibitory effect of NH₄C1, time of addition is not very important, but the length of treatment is rather critical. Ammonium chloride attenuated the synthesis of almost all the proteins in IPNV-infected CHSE-214 cells. Thus the primary effect of NH₄C1 on virus-infected host cells is to inhibit the synthesis of proteins resulting in the delay of IPNV growth. Therefore, we conclude that IPNV penetration into CHSE-214 cells does not require the low-pH dependent activity of lysosome.

근래에 지어진 건축물의 경우 지진에 대한 안전성을 확보하고 있지만 1983년 개정이전의 건축물은 내진설계가 미반영 되어 있어 지진에 대해 매우 취약하다. 본 연구에서는 내진성능이 부족한 기존 건축물의 지진 발생 시의 안전성 확보를 위한 내진보강 방안으로 격자강판 내진보강벽을 제안한다. 축력과 반복수평력을 받는 성능실험을 수행하였으며, 실험체는 벤치마크 용도로 순수 철근콘크리트 프레임(BM-RC)과 프레임 내부에 격자강판 내진보강벽(SW-RC)을 설치한 2개의 실험체를 제작하여 실험을 수행하였고, 축력과 횡하중 가력을 위하여 500kN용량의 엑츄에이터 2대와 2,000kN용량의 엑츄에이터 1대를 사용하였다. 실험결과를 통해 벤치마크 실험체와 비교하여 강도, 강성, 연성 및 에너지소산능력을 평가하였다. The recently constructed buildings are ensuring seismic safety with enhanced design criteria. But, the buildings unapplied enhanced design criteria are very weak. In this study, steel grid shear wall is proposed as a solution of seismic retrofit to ensure safety of the existing buildings for the earthquake. And the structural performance experiments were carried out under axial force and cyclic lateral loads. The two specimens were made of a reference RC frame and steel grid shear wall in-filled RC frame. The test setup configured with two dynamic actuators, for the axial force with a 500kN capacity actuator and for the cyclic lateral load applied with the 2,000kN actuator. Compared with control specimen, the strength, stiffness, ductility, energy dissipation capacity of the seismic retrofit structures is evaluated.

To investigate the etiology, pathogenicity and virological properties of NYJ-1-87 strain of Aujeszky's disease virus (ADV) that was isolated from the diseased piglet in Korea, the virus at $10^{6.0}TCID_{50}/0.1ml$ was inoculated intranasally and subcutaneously into 30 to 35 days-old piglets. Results obtained through the experiments were summarized as follows. 1. Ten of the infected piglets were clinically observed for 15 days. On the 2nd day post-inoculation(pi), the signs of pyrexia, anorexia and convulsion were noted. On the 4th to 7th days pi, nervous signs of incoordination and intermittent spasm were shown in the most of piglets, and one out of 5 piglets infected intranasally was died with severe nervous signs at the 7th day pi. The signs became relieved on the 8th day pi and all of remainder were completely recovered on the 13th to 14th days pi. 2. In hematological study, prominent decrease in the number of total leukocyte and lymphocyte was shown in the ADV-infected piglets on the 6th day pi. On the 8th day pi, the cell numbers were slightly increased and returned to normal level on the 10th day pi. 3. Viral excretion of the ADV-inoculated piglets was examined by swabbing of nasal and oral cavities, and rectal feces. During the periods of the 3rd to 11th days pi, the virus was excreted intermittently from nasal and oral cavities, and rectal feces. The nasal excretions were shown the highest virus concentration of $10^{5.2}TCID_{50}/0.1ml$ at the 5th day pi. 4. Recovery of the inoculated virus from various organs of the piglets that were died or experimentally slaughtered was attempted, and the virus was isolated from the tissues of brain and tonsil by the cultured cell-inoculation method. The highest recovery rate was noted in the tonsil. By indirect immunofluorescence antibody assay using ADV-monoclonal antibody, the viral antigens were detected in tissues of spleen and liver as well as brain and tonsil on the 7th to 9th days pi. The virus was not isolated from blood and the tissues of lung and kidney throughout the experiments. 5. Titers of virus neutralizing antibody in the piglets experimentally infected with ADV became increased after the 6th to 9th days pi in both of intranasal and subcutaneous inoculation showing the highest titers of 64 to 128 on the 29th day pi. When the antibody levels were measured by radial immunodiffusion enzyme assay, the reactive diameter was enlarged to be positive after the 4th to 6th days pi in both of intranasal and subcutaneous inoculation showing the largest diameter of 13 to 14mm on the 29th day pi.
