Purpose: To determine the surgical outcome of intermittent exotropia according to preoperative retinal correspondence with the Bagolini striated glasses test and the relationships between the Worth-4-dot test or stereoacuity with the B-VAT test. Methods: We analyzed retrospectively preoperative fusion statuses with the Worth-4-dot test, stereoacuity with the B-VAT test and retinal correspondence with the Bagolini striated glasses test to determine any possible relationships with surgical outcome. The surgical outcome and binocular function were further investigated six months postoperatively in 114 patients who had undergone surgery for intermittent exotropia. Results: The surgical outcome according to preoperative fusion status and stereoacuity was not statistically significant(p=0.38, p=0.59). whereas, preoperative retinal correspondence with the Bagolini striated glasses test was statistically significant(p<0.01). More over there was a relationship between retinal correspondence and fusion status or stereoacuity(p<0.01, p<0.01). Conclusions: The preoperative Bagolini striated glasses test was the factor predicting a favorable surgical outcome and there was a relationship between the preoperative Worth-4-dot test and the B-VAT test.

Genetic algorithms(GAs) are adaptable to discrete and constrained problems and do not require continuity, unimodality, and derivatives of function. But GAs have a demerit of late convergence, which means to be examined many individuals until find the best individual. And especially much time is required to compute the constraints of an individual in large scale or nonlinear structural problem. So it needs to be developed the genetic algorithm to converges fast in small population. Although the selected algorithm is superior, it's performance could be very fluctuate depending on search space. And it is possible to vary and adapt the algorithm to a placed circumstance. Therefore it is very important for user to create more efficient algorithm. In this paper, micro genetic algorithm effective in small population size is used to save computing time in size optimization of geometrically nonlinear space truss. But in practical structural size optimization problem, many design variables are needed and search space is very complicated. Also optimum solutions exist at the corner (boundaries between feasible and infeasible regions) of the search space. In this case, micro GAs exist so far are liable to fall into dead corner and some genetic operators of those do not work well because the outcomes of the operator are apt to be infeasible. To cope with these problem it is proposed to reduce the intensity of penalty in order to extend the boundaries of search space and to use the hybrid genetic algolithm by gradient-like-selector to converge fast and avoid the genetic drift as a result of copies.

We introduce an unsupervised-learning-based technique to analyze the Radio-Frequency (RF) scattering signals from a target and identify the shape of the target. A collection of scattering points on the target was obtained from the interceptor’s RF seeker; then, the Expectation-Maximization (EM) algorithm was applied to classify them and find the statistical characteristics of each cluster. The computation results provide good estimates on the general shape of the target, which includes the length and the location of specific spots, even without sufficient prior knowledge. The proposed technique was verified via Monte-Carlo simulations using the target Radar Cross-Section (RCS) models and the probabilistic models of the seekers. The algorithms were also implemented on the embedded flight computer, and the real-time location performance under realistic environmental conditions were validated via a series of experimental tests.

Short-term acute toxicity of synthetic detergent(harmful and non-harmful detergents) to crusian carp, Carassius auratus was examined by static bioassay. The crusian carp was exposed to 10 different concentration of synthetic detergent for 240 hours in order to determine median lethal concentration(LC50). In case of harmful detergent, the 100% mortality was showed within 72 and 24 hours for 14 and above 20 ppm, but showed below 30% for until 10 ppm. For the non-harmful detergent, 80% of mortality was appeared for 450 ppm only The 48hr, 96hr and 240hr of median lethal concentration was found 12.85ppm, 11.86ppm !ind lO.36ppm respectively. The permissible toxicant concentration of acute toxicity to crusian carp was 1.19ppm. Gill tissue of dead crusian carp showed necrosis and blood vessel also damaged Epithelium of gill lamellae showed pronounced change in even 8 ppm below. During the test period, gills of survival animals appeared also change for non-harmful detergent. So, animals showed effection of detergent even though animals exposed to non-harmful detergent for long times.

나노 기술의 급격한 발달에 따라 나노미터 수준의 정밀도를 갖는 초정밀 측정 기술이 여러 분야에서 요구되고 있다. 헤테로다인 레이저 간섭계를 이용하여 초정밀 위치 측정을 하려고 할 때, 광학기기 자체의 불완전함에서 발생하는 비선형성 오차는 주요한 요소로 작용한다. 본 논문에서는 헤테로다인 레이저 간섭계 시스템에서의 비선형성을 보정해주기 위해 적용형 알고리즘을 제안한다. 기준 입력인 정전용량센서와 최소자승법을 이용하여 보정변수를 구한 후, 반복 최소자승법을 이용하여 비선형성에 따른 타원 위상을 비선형성이 보정된 원 위의 위상으로 사상시킨다.

1994년 2월 12일 경주시 백반동의 폐사한우에서 분리한 Bacillus anthracis로 여러가지 실험을 실시하여 다음과 같은 결과를 얻었다. 1. 생화학적 검사에서 그람양성, 아포와 협막을 형성하고, 탄저침강소 반응, 카타라제, V-P반응, 질산염 환원, 젤라틴 액화, 전분 가수분해, 혐기하에서 성장, 글루코스 분해, 카제인 가수분해, PH 5.7에서 성장, 7% NaCl 성장 등에서 양성이며, 운동성, 우레아제, 시트르산 이용, 인돌 산생, 아리비노즈,만니톨,키실로즈 분해, 45-65℃에서 성장 등에서는 음성이었다. 2. 각종 배지에서의 배양성은 24시간까지는 BA, Br A, TSA에 가장 좋았고, 72시간까지는 BA, BR A, NA, TSA에서 배양성이 좋았다. Colony배양성으로는 BA대용으로 Br A가 가장 좋았다. 3. 각종 동물 적혈구에 대한 β-용혈성시험은 대부분의 동물 적혈구가 36시간부터 용혈이 시작되어 48시간에 완전히 일어났으며, 산양 적혈구는 60시간부터 용혈이 시작되었다. 4. 항균제에 대한 감수성은 AM,CR,TE,ENR에 감수성이 가장 컷고, 그 다음은 GM,AN,DFX,S,P,TyLO,N,KM,C,E,Lins+SP,NN,CC,CFP,CB의 순이었으며, L,XNL,TIA에는 저항성을 나타내었고, CL,SXT에는 전혀 감수성이 없었다. 5. 탄저균을 피하접종하였을 때 rat와 chicken은 전혀 감수성이 없었고, mouse가 가장 감수성이 좋았고, 그 다음은 goat, hamster, guinea pig, rabbit의 순이 었다. 6. 탄저균 접종으로 폐사된 사체를 37℃ 부란기에 보존하였을 때 개복하지 않은 경우에는 80시간이후부터 탄저균이 검출되지 않았고, 개복한 상태에는 360시간이후에도 검출되었다. 7. 탄저균을 실험동물에 접종시 대체적으로 접종균수가 많을수록 빨리 폐사하였으며, 단지 420개의 피하주사에서도 폐사하였다. 8. 탄저균을 접종한 hamster의 혈액도말표본을 37℃에 보존시는 5시간, 32℃에서는 6시간, 실온에서는 9시간, -4℃와 -20℃에서는 10시간째에 아포를 형성하기 시작했다. 9. 탄저균을 실험동물의 피하 및 경구접종하였을 때 피하접종한 mouse, rat의 분변에서는 탄저균이 회수되지 않았고, 경구접종한 mouse,rat,chicken의 분변에서는 탄저균이 회수되었다. 10. 탄저균에 대한 가장 좋은 소독제는 formalin과 승흥이었으며, phenol과 cresol은 소독력이 약하였으며, NaOH는 소독력이 거의 없었고, ethanol은 전혀 소독력이 없었다. This study was conducted to investigate the characteristics of B, anthracis isolated from Anthrax in the Baeban Dong, Kyong-Ju in Feb. 12. 1994. 1. In biochemical features, B. anthracis showed a gram-positive rod, non-motility, sporulation and capsulation. It was positive in catalase, V-P reaction, nitrate reduction, gelatin liquefaction, starch hydrolysis, anaerobic growth, acid from glucose, casein hydrolysis, growth at PH 5.7, growth in 7% NaCl, but negative in urease, citrate utilization, indole production, acid from arabinose,manitol,xylose, growth at 45-65℃. 2. B. anthracis grew well on BA, Br A and TSA after incubation for 24 hours. The organism grew well on BA, Br A, NA and TSA after incubation for 72 hours. The good media for colony was Br A instead of BA. 3. On 5% blood agar by laboratory animal, β-hemolysis was produced from 36 hours to 48 hours incubation. There was perfect β-hymolysis after incubation for 48 hours. On the other side β- hemolysis was begun on 5% goat blood agar after incubation for 60 hours. 4. In the test of antimicrobial susceptibility, B. anthracis was very sensitive to AM, CF, TE and ENR. The orders of sensitivity were as follows: GM, AN, DFX, S,P, TYLO, N, KM, C, E, Lins+Sp, NN, CC, CFP and CB. B. anthracis was not sensitive to L, XNL, TIA, CL and SXT. 5. B. anthracis had no sensitivity to direct inoculation of rat and chicken, after subcutaneous injection. It was very sensitive to mouse. And the orders of sensitivity were as follows : goat, hamster, guinea pig and rabbit. 6. The dead laboratory animal which had been inoculated with B. anthracis preserved at 37℃ incubation, B. anthracis did not cultivate on non-dissected animal after 80 hours but cultivate on dissected animal after 360 hours. 7. The rapid death of animals could cause by high concentration of B. anthracis, even died from 420 after S.C. 8. In the blood smeared samples of hamster from inoculation with B. anthracis, the spore germinated in 37℃ after 5 hours, in 32℃ after 6 hours, in room temperature after 9 hours and in -4℃ to -20℃ after 10 hours. 9. B. anthracis inoculated to laboratory animal after S.C or P.O. mice and rats feces did not cultivated with B. anthracis after S.C, but cultivated with B. anthracis after P.O. 10. In the test of disinfectant, the most effective disinfectant was HgCl2 and formalin Phenol and cresol was less effective than HgCl2 and formalin. NaOH and ethanol was non-effective.
