The objectives of the current study were to evaluate the therapeutic effect of dioctahedral smectite (smectite) against calf diarrhea caused by pathogenic E. coli and/or Salmonella typhimurium. In this study, 20 calves (aged 2~3 months) with diarrhea were used for evaluation of the efficacy of smectite on calf diarrhea with 20% smectite suspension in PBS. Calves received 10 ml smectite suspension three times per day after feeding, and fecal samples were collected at the gate of treatment and on the first, second, third, fourth, and fifth day after administration. On the fifth day after treatment with smectite suspension, the diarrhea index showed a significant decrease in the treated group, compared to the control group (P<0.001). The number of pathogenic E. coli in feces of the treated group was significantly decreased, compared to each control group from the second day after treatment (P<0.001), and that of Salmonella typhimurium was significantly decreased from the first day after treatment (P<0.05). According to the results of the current study, 20% smectite suspension had a therapeutic effect on diarrhea caused by E. coli and/or Salmonella in calves.

The purpose of this study is to review (or, investigate) the life of Won Guk Lee. He is the creator of Chung-Do-Kwan, which is one of the five original Taekwondo kwans. Data was gathered from advanced research, newspapers, documentaries, the Internet, magazines, and journals etc. Thus, we were able to create a sequence of events based on the research data. First, we can say that in Won Guk Lee``s career, he created Chung-Do-Kwan and brought Dangsoodo to Korea. These events have had a significant development on Taekwondo. Second, Taekwondo curriculum, which was published by Won Guk Lee, established the foundation of Taekwondo poomsae, as well as giving us the pure spirit of Korean martial arts.

The purpose of this study is to investigate the variation of pore size distribution of the coal-based extruded activated carbon. The extruded activated carbon was prepared by extruding the mixture of coal powder and coal tar. Pore size distribution of the extruded activated carbon was compared with that of the extruded coal and the extruded char. Also it was compared with that of the crushed activated carbon, raw coal and char. The extruded coal had coarser surface than that of raw coal. Macropores of the extruded coal were funned near 10,000Å in diameter during carbonization process and steam penetrated easily between particles and were growing between 3,000Å and 20,000Å in diameter during activation process.

가속수명 시험을 통한 PWB의 제품 신뢰성 평가 연구

全永鎬,權彛章 弘益大學校 科學技術硏究所 1995 科學技術硏究論文集 Vol.6 No.-

This paper describes a highly accelerated life test (HALT, USPCBT) method for rapid qualification testing of STH PWB(Silver Through Hole Printed Wire Boards). This method was carried to be an alternative to the present time-consuming standard 1344 hours life testing(THB). The accelerated life test conditions were 121℃ 95%R. H. at 50V bias and without bias. Their results are compared with those observed in the standard 1344 hours life test at 40℃/95%R.H. at 50V bias and without bias. The studied were focused on the samples' time-to-failure as well as the associated conduction and failure mechanism. The abrupt drop of insulation resistance is due to the absorption of water vapour. And the continuous drop of insulation resistance is due to the Ag migration. The ratio of time-to-failure of HALT(USPCBT) samples to THB was 25 and 11 at 50V bias and without bias respectively.

신경망 확산망을 이용한 항만물류 연속 음성인식시스템에 관한 연구

항만 물류 시스템의 인간공학적인 설계가 요구되고 있다. 특히 물류(컨테이너)의 선, 하적시 컨트롤 문제는 인간에게 과부하를 주고 있어 시스템의 음성화가 요구되고 있다. 본 연구에서는 연속음에서 음성구간을 추출하여 각 음성을 확산필터뱅크를 통해 특징을 추출하고 신경망 인식기에서 인식하여 인식결과를 항만물류 음성인식시스템에 사원번호 인식에 사용하였으며 사원번호 입력화면에서 숫자로 디스플레이 되도록 설계하였다. 인식결과는 각 숫자음과 "확인", "삭제" 등으로 나타내었다. 전체적으로 인식률은 96%을 보이고 있으며 100% 인식결과를 나타내는 음도 있었지만 숫자 "사"의 경우 인식률 80%로 약간 낮은 결과을 나타내었다. 추후에는 패턴의 다양화와 전 처리에서의 개선 등으로 문제점을 보완 하여야 할 것이다.

This study carried out to know the effects of Tetragonia on tumor immunities and the inflammatory responses. The tumor immunities were measured by checking the antibody dependent on cellular cytotoxicity(ADCC) and natural killer(NK) cell activity. The effects of Tetragonia on inflammatory responses were measured by evaluating the amount of reactive oxygen intermediate(ROI) in the neutrophils and macrophages. The innate immunity was evaluated by measuring the phagocytic activity of macrophages. The results obtained were as follows : 1. Tetragonia increased the antigen specific ADCC without affecting antigen non specific NK cell activity in tumor immunities. 2. Tetragonia severely decreased such ROI as O^-_2 and H_2O_2 in both neutrophils and macrophages. 3. Tetragonia increased the phagocytic activity of macrophages. The results of this study suggest that tetragonia might be effective on tumor immunity and such inflammatory diseases as rheumatoid arthritis and allergic diseases.

자외선에 의하여 유발되는 염색체 이상과 자매 염색 분체 교환에 미치는 calmodulin의 영향

이천복,김장호 慶星大學校 1993 論文集 Vol.14 No.4

The present study was performed to elucidate not only the effects of clamodulin (calcuim receptor) on the damages and their recovery processes at the chromosomal level, but also the possible relationship between chromsome aberration and sister chromatid exchange(SCE). To obtain a clear understanding of them ,the experiment were undertaken to the effects of trifluoperazine (Tfp; calmodulin inhibitor) on chromosome aberrations and sister chromatid exchchanges induced by ultraviolet light(UV). The results obtained were as follows: 1)Both the chromosome aberrations and sister chromatid exchanges were not induced by the treatment of various concentration and hours of Tfp. 2) Tfp inhibited chromosome aberrations induced by UV-light regardless of the concentration and hours of treatment. 3) In the groups treated with 5μM Tfp for 1 hour after exposure to UV-light, sister chromatid exchanges induced by UV-light were little effected. However, in the groups treated with 10μM or 20μM Tfp, sister chromatid exchanges induced by UV-light increased with Tfp unlike chromosome aberrations. 4) Treatment of Tfp for 36 hours after exposure to UV-light increased the sister chromatid exchanges UV-light. The aspects of increase were proportional to the concentration of Tfp. These data indicate that Tfp itself dose not induce chromosome aberrations and sister chromatid exchanges, but is concerned in chromosome aberrations and sister chromatid exchanges induced by UV-light; that is, it has the ability to decrease chromosomal aberrations but to increase sister chromatid exchanges. In conclusion, calmodulin has an effect on the damages and their recovery at the chromosome level, the induction pathways of chromosome aberrations and sister chromatid exchanges seems to be controlled by the different mechanisms.

Results of examined effect of calcium and phosphate on granular sludge of methane production bacteria in treating paper and pulp making wastewater by up-flow anaerobic sludge blanked reactor were summarized as follows: 1. Generally granulated month of granular sludge was taked five and six months in case of not dose calcium and phosphorus ion but when artificial dosing calcium and phophorus concentration ratio 80mg/l versus 192mg/l was appeared 75 day on the granulated day. 2. Perfection of granular sludge by scanning electron microscope mere photo-graphed in COD loading rate 6.0kg COD/㎥ day and granular sludge diameter mas from 1.2mm to 3.9mm and settling velocity was 60cm/min. 3, Results of analysis calcium and phosphorus of one gram granular sludge were obtained 33.81 mg, 17.14 mg. so that artificial dosing calcium and phosphorus of chemical factor were effected in granulation process. 4. Methane production per kg COD removal was obtained from 0.2㎥CH4/kg CODrem to 0.31㎥CH4/kg CODrem, so that this study is not reached 0.35㎥ theoretical methane production per kg COD removal for nonbiodegradable substrate of wastewater.
