We evaluated the efficacy of the liquid form of enrofloxacin against poultry respiratory and digestive infections, the major problems in the poultry industry, from diverse diagnosis viewpoints. Results obtained through this study were as follows: 1. The liquid form of enrofloxacin showed good acceptability to poultry owing to no abhorrence to the drug by chickens, which indicated its suitability for mixing in drinking water. 2. The application of the enrofloxacin formulation improved the productivity of the chicken farm to a great extent by lowering the death toll of chicken raised in the farm. 3. The use of the drug shortened the days to the market, and increased the body weight at the time of marketing. 4. Preventive and therapeutic effects of the liquid enrofloxacin were observed higher than ampicillin, a major antibiotic used in poultry farming. From above results, the liquid form of enrofloxacin would find its use for the prevention and treatment of digestive and respiratory infections, let alone the growth promotion and feed efficiency, especially in the chicken farming practice.

In this study the antimicrobial spectrum and sensitivity of a liquid formulation of enrofloxacin against the major six pathogenic bacteria isolated from the diseased poultry in Korea were evaluated in comparison with ciprfloxacin (CFX), gentamicin (GM) and penicillin (PC). A liquid form of enrofloxacin, a test material and ciprofloxacin showed at least 83% antibacterial activity against all of six test pathogenic microorganisms at the fixed concentration of 10 ㎍/㎖. Gentamicin and penicillin revealed much lower antibacterial activity at the same condition. We evaluated the liquid form of enrofloxacin as having widespread antibacterial spectrum against poultry infections. The liquid form of enrofloxacin showed potent antibacterial activity, with the MIC range being 0.12∼2 ㎍/㎖ against Gram positives, 0.06∼2 ㎍/㎖ against Gram negatives and 0.5∼2 ㎍/㎖ against Mycoplasma spp. These values were equivalent to or somewhat higher than those of ciprofloxacin, but much lower than those of gentamicn and penicillin. This new liquid form of enrofloxacin would find its way in application of mixing with drinking water for the prevention and treatment of diverse infections in chickens.

The helicopter system is non-linear and complex. Futhermore, because of absence of an accurate mathematical model, it is difficult accurately to control its attitude. Therefore, we propose a fuzzy control technique to control efficiently its elevation angle and azimuth one. This controller is on the basis of expert's knowledges and his experiences. The simulation results using MATLAB are introduced.

The X-ray quality of continuous X-ray beam depends upon the half value layer which varies according to the geometric conditions, filtration thickness, and the amount of tube voltage(kVp). We compared inverter type X-ray apparatus with conventional single phase 2 peak and three phase 12 peak apparatus in the following aspects X- ray quality in various thickness of added filter with different kVp. The X-ray quality of single phase 2 peak X-ray generator showed increase to added filter and tube voltage. The half value layer is increased the thicker the filter and the higher the kVp. The X-ray quality of inverter type and three phase 12 peak showed increase as compared against of single phase 2 peak X-ray generator.

Inverter generators are now on the way for further development to eliminate single phase generators and three phase generators. We compared inverter type X-ray apparatus with conventional single phase 2 peak and three phase 12 peak apparatus in the following aspects X-ray output to tube voltage, linearity of X-ray output to mA and exposure time, transmission dose in various thickness of aluminium absorber with different kVp. The output, linearity of inverter type and three phase 12 peak showed increase as compared against of single phase 2 peak X-ray generator. The transmitted doses of inverter type and three phase 12 peak X-ray generators were more increased than single phase 2 peak X-ray generator.

In this paper, as a performance analysis of parallel processing, a static data flow model and a Von Neumann model is used. Simulations are performed and the results are analyzed. The CPI and MIPS are used to analyze the performance of two models at a real time speed. In general, Von Neumann models make well use of locality, but data-flow models have overheads that are due to producing token and no use of locality.

In this paper, high level of MPEG-2 video MP@HL decoder is designed and follows ISO/IEC 13818-2 standard specification. MPEG-2 video decoder consists of system processign board, slice processign board, and motion processing board, which is compatible with MPEG-TS and MPEG layer-2. Each board represents schematic level design and external interface.

The slit moving apparatus which determine the advantage of opt-sentive material in sensitometry was produced and was compared to the distance scale method which has low variation in accuracy and in reproduction, and the results showed that the unique value agree. The slit moving apparatus is expect to reduce space which needs widely for sensitometry in distance scale method and improve convince to user.

전자 디지털 컴퓨터가 발명된 지 40년 여년이 지났고 현재의 컴퓨터는 모든 기능을 그래픽 환경에서 구현하고 있으며, 여러 가지 부가적인 기능을 가지고 있다. 초기의 수치계산에 치우쳤던 컴퓨터의 기능은 지금은 많은 멀티미디어 기능을 내장하고 있다. 수치계산에서 문서화 작업, 자동제어, 음악, 그림에 이르기까지 앞으로의 용도를 예측하기 어려울 정도다. 처음에는 영어 철자나 기호 등을 이용해 점자같은 처리를 했던 그래픽이 지금은 모든 것을 표현하는 완벽한 예술의 도구로 자리잡았다. 기존의 이미지 뷰어에서는 정영상과 동영상에 별도의 틀이 있었지만, 통합 환경은 없었다. 본 논문에서는 다양한 포맷의 디스플레이, 확대, 축소, 프린트 기능과 동영상을 디스플레이할 수 있는 통합 환경을 구현하였다.
