  • In this paper we define the probability models for determining the disparity map given stereo images and derive the methods for solving the problem, which is proven to be equivalent to an energy-based stereo matching. Under the assumptions the difference between the pixel on the left image and the corresponding pixel on the right image and the difference between the disparities of the neighboring pixels are exponentially distributed, a recursive approach for estimating the MRF regularizing parameter is proposed. The proposed method alternates between estimating the parameters with the intermediate disparity map and estimating the disparity map with the estimated parameters, after computing it with random initial parameters. Our algorithm is applied to the stereo matching algorithms based on the dynamic programming and belief propagation to verify its operation and measure its performance.

  • In order to find out the effect of temperature and shading on the growth and major disease infection of Eutrema wasabi Matsum., experiments were at growth chamber condition and field. Plant height, petiole and rhizome of wasabi were obvious decreased with increase the temperature, from which the optimum air temperature for the plant growth were estimated to be 17$^{\circ}C$. The light intensity of the treatment with 75% shading net was favorable to the length of main rhizome, rhizome weight and whole plant weight. Infection ratio of black leg and soft rot were increased at high temperature condition, however their infection ratio were decreased with increase the shading condition.

  • The effect of two-fluid fogging system on the control of Bemisia tabaci in tomato cultivation was evaluated in a greenhouse. The number of Bemisia tabaci was decreased by 87% from the fog treatment for 7 days. During the fog treatment, the mean daily temperature was decreased by $2^{\circ}C$ and the mean daily relative humidity was increased by 3~4% as compared to the non-treatment. The reduction of Bemisia tabaci in the treatment might not be resulted from the differences in temperature and humidity in the greenhouse. The sound coming from the two-fluid fogging system did not affect when it was operated without water inside. Therefore it was concluded that water droplets coming out the nozzle reduced the growth and the movement of whiteflies because the suspension of tiny water droplets were attached on the skin of whiteflies.

  • 구순 구개열 환자의 악교정 성형수술로 구강내 Le Fort II 골절단술이나 비중격 성형술이 많이 이용되는데, 이때 비골의 외측골절단술을 요하며, 이에 대한 술 후 합병증으로 비루관의 폐쇄나 비골의 분쇄골절 등이 발생할 수 있어, 악안면기형 환자를 다루는 구강악안면외과의사에게 비루관의 웅용해부학적 연구는 중요하다. 본 연구의 목적은 교합면을 기준으로 촬영된 컴퓨터 단충 촬영에서 비루관의 위치와 크기를 조사하는데 있다. 2000년 7월부터 2003년 2월까지 서울대학교병원 구강악안면방사선과에서 컴퓨터 단층촬영을 시행한 환자 62명을 대상으로 비상악봉합선에서 비루관까지의 최단거리와 비루관의 최대반경과 최소반경을 측정하였다. 우측비상악 봉합선에서 비루관까지의 거리는 5.68mm이고, 좌측은 5.67mm였다. 좌우 및 성별간의 차이는 없었다. 이의 해부학적 지견은 악기형 수술시의 비루관 폐쇄라는 합병증의 예방책으로 기여하리라 생각된다.

  • This study was carried out to isolate and identify the yeasts from the the composts, which were effective to reduce odor of the pig feces, and to investigate their physiological properties. In yeasts, one of 30 isolates was obtained on 10% pig feces extract medium. Judging from the morphological and biochemical characteristics, the CY-10 isolated from the compost were identified as Candida rugosa. This isolated strain showed the deodorizing activity by reducing the concentration of $NH_3$ and R-$NH_2$ than that of the control. The CY-10 had completely utilizing butyric acid and iso-butyric acid including 10% pig slurry of the volatile fatty acids, which are the specific malodorous agents of pig feces. Compared to control, this yeast was found effective for decrease in $NH_4$-N, Soluble-N and BOD, 20%, 12.6%, and 9.82% respectively.
