본 연구는 넙치의 수온 스트레스에 대한 사료첨가제 (미역 5%, 미역 10%, 어보산 0.5%, 고추냉이 잎 2%, 고추냉이 줄기 2%)의 영향을 혈액학적, 면역학적 측면과 Edwardsiella tanda를 사용하여 질병에 대한 저항성으로서 평가하였다. 혈장의 글루코즈와 콜티졸 농도는 1차 수온 변동 후 대조구에 비하여 미역 5%와 고추냉이잎 2% 첨가구에서 유의적으로 낮게 나타났다(P〈0.05). 1차 수온 변동 후 혈장 라이소자임 활성과 E. tarda의 공격 시험 후 생존율은 미역 5%첨가구에서 대조구에 비하여 유의적으로 높게 나타났다(P〈0.05). 본 실험 결과 미역 5% 첨가 사료 투여는 넙치의 스트레스 상태에서 질병 감염에 대한 저항성을 높일 수 있을 것으로 사료된다. The effect of each dietary supplements (Undaria 5%, Undaria l0%, Obosan 0.5%, Wasabi leaf 2%, Wasabi stem 2%) on the water temperature fluctuation in juvenile olive flounder (Puralichthys olivaceus) was investigated. The response to stress was assessed in terms of effects on haematological and immunological, and resistance against Edwurdsiella tarda infection. Plasma glucose and cortisol levels were significantly lower in 5% undaria and 2% wasabi leaf supplement groups than the controls after the first change of water temperature (P<0.05). The plasma lysozyme activities and the survival rates from E. tarda infection were significantly higher in the 5% undaria supplement groups than the control (P<0.05). These results suggest that the 5% undaria supplement seems to be contributable to the increased disease resistance on olive flounder.

The following results were obtained through the clinical review and CT study of 12 cases of Tuberculous meningitis which were treated at the Soonchunhyang Hospital (Department of Pediatrics) during the period of 1/2 years from March 1981 till September 1982. 1. The highest incidence by age was noted as 6 6.7% under the age of 3 years. Male to female ratio was 1 : 1.4. 2. The chief complaints on admission were in order of frequency, high fever. vomiting, coughing and irritability. Meningeal irritation sign was noticed in 75% of cases. 3. Tuberculin test revealed positive in 75% of cases. 4. Chest x-Ray revealed tuberculous lesion in 6 6.7% of all cases and miliary tuberculosis was found in 33.3% of all cases. 5. In 66.7% of cases leukocyte count in the CSF was 50∼500/㎣. In 75% of all cases, differential count of lymphocyte was over 75%. Protein level ranged from 50 to 300mg% in 83.3% of all cases. Sugar level in the cerebrospinal fluid was decreased below 40mg% in the 58.3% of all cases. 6. CT findings were as follows ⓐ obliteration of the basal cisterns were observed in 2 out of 7 cases (28.6%). ⓑ Intence abnormal contrast enhancement of the basal cistern were observed in 1 out of cases (14.3%). ⓒ Moderate to marked dilatation of both lateral ventricles were observed in 4 cases(57%) ⓓ I case of cerebral infarction was observed. 7. As for clinical stage of Tuberculous Meningitis 10 cases were in stage l & 2 on admission and all of them were recovered. 2 cases were in stage 3, 1 case died and 1 case recovered. Mortality rate was 8.3%.

This experimental study is about characteristics of flow-induced vibration of elastically supported two circular cylinders in side-by-side arrangement. In particular, the characteristics of t1ow-induced vibration of the two cylinders are investigated with changing flow speed at each spacing ratio L/D (L: space between two cylinders, D: diameter of cylinder). Flow patterns around the vibrating two cylinders are also investigated by flow visualization with reproducing the state of elastically supported vibration accurately in forced vibration apparatus. It is clarified that characteristics of flow-induced vibration of two cylinders are changed with switching flow passing through the two cylinders.

In this paper, a global compaction algorithm of microprograms, which combines microoperations (MOP's) into effective microinstructions (MI's) by global data analysis over basic blocks, is proposed. The algorithm reduces total execution time and control memory space, and improves the execution efficiency through a broad view of microprograms. Also, it is implemented and tested on virtual machine, and the result of it's compaction is verified.
Catalytic activity and characterization of V2O5/γ-Al2O3 for ammoxidation of m-xylene system
설용건,Yukwon Jeon,Sung wook Row,Altansukh Dorjgotov,Sang Duek Lee,Kyeongseok Oh 한국화학공학회 2013 Korean Journal of Chemical Engineering Vol.30 No.8
An ammoxidation of m-xylene was evaluated in a fixed-bed reactor using V2O5 on various oxides. Catalysts were prepared by wet impregnation method. At first, the loading of V2O5 was varied from 5 wt% to 20 wt% on γ-Al2O3support to estimate the most effective amount of V2O5. Second, the effect of catalyst supports was examined at 10 wt%loading of V2O5. V2O5/TiO2 and V2O5/SiO2 catalysts were employed to compare the ammoxidation reaction with V2O5/γ-Al2O3. Most catalytic activity was observed when γ-Al2O3 was used as a support. Careful characterization was followed by physicochemical techniques, such as BET measurement, X-ray diffraction (XRD), Raman spectroscopy and temperature-programmed reduction (TPR). The results provided the clue that monolayer V2O5 was favorably dispersed on the surface of γ-Al2O3 up to 10 wt%, which led to the highest yield of isophthalonitrile (IPN).
