거대고리 리간드는 금속이온과 선택적으로 결합하는데, 이를 이용하여 에멀젼 액체막을 통한 금속이온의 이동에 관하여 연구를 수행하였다. 금속이온은 유기층에 있는 운반체에 의하여 source phase에서 receiving phase으로 이동한다. 운반체로는 거대고리 리간드인 DBN_(3)O_(3)를 사용하였다. 여기에서 에멀젼 액체막을 통한 금속이온의 이동에 관한 요인과 어떤 금속이온의 선택적 분리에 관하여 검토하였다. 금속이온과 거대고리 리간드 그리고 금속이온과 receiving phase내에 있는 음이온에 대한 안정도 상수를 금속이온의 선택적 이동에 대한 척도로 조사하였다. 납이온이 혼합 용액에서 다른 금속이온보다 높은 이동속도를 나타내었다. Receiving phase내의 음이온이 금속이온의 이동에 중요한 역할을 한다. Receiving phase내에 있는 NO_(3)^(-)을 S_(2)O_(3)^(2-) 대치하면 이동량이 증가함을 보였는데 이는 Pb^(2-)-S_(2)O_(3)^(2-) 상호작용이 Pb^(2+)-NO_(3)^(-) 상호작용보다 크기 때문이다. Macrocyclic ligand has been know to selectively bind with metal ions so that ability applied for the transport of metal ions across the emulsion liquid membrane in this study. The metal ions are transproted from the source phase to the receiving phase by the carrier of the organic phase. Several factors involved in the transport of metal ions acrose the emulsion membrane we reported here and these factors proveided the informations for the selective seperation of some metal ion. Stability constants for cation-macrocyclic ligand and metal ion-anion receiving phase interaction are examined as parameters for the prediction of metal ion transport selectivities Pb^(2+) was transported higher rates than the other metal ions in the mixture solution. The interaction of metal ion to anion in receiving phase is important. S_(2)O_(3)^(2-) in replacement of NO_(3)^(-) in the receiving phase enhances the transport of pb^(2-) since Pb^(2-)-S_(2)O_(3)^(2-) interaction is greater than Pb^(2+)-NO_(3)^(+) interaction.

Recently increased attention has been given to utilization of agricultural waste products to produce food, feed, fertilizer and as a raw material in home and foreign countries. Such utilization could not only help maximize resources but at the same time minimize waste disposal problems. On this purpos, studies were conducted to investigate the possibility of utilizing of agricultural waste seeds-gourd, cucumber, peach, citron and hardy orange. The results determined could be summarized as follow: 1. The waste seeds contained 16-32% of crude protein, 25-46% of crude fat. Determined food energy values averaged 589kcal/100g. Especially, Peach seed were contained higher content than other waste seeds in crude protein and crude fat. 2. Of the oil charcteristics, iodine value was in the range of 100-154, saponification value was in the range of 124-188 and acid valve was about 1.1. 3. The seeds were found to have valuable amounts of essential minerals. The content of iron in gourd. cucumber and citron seeds were in the range of 48-90ppm and the content of copper. zinc and calcium were plentyful than that of other food resources. 4. The lipid fractions obtained by silic acid column chromatography were mainly composed of over 87% neutral lipid, whereas the content of glycolipid and phospholipid were 1.0-5.3% and 1.5-7.3% respectively. 5. Among the neutral lipid in total lipid, triglyceides were predominant (68.7-78.1%) with smaller amounts of the others. Among the glycolipids, esterifed steryl glycosides (41.2-52.4%), cerebrosies (20.8-28.6%) and steryl glycosides (12.7-24.3%) were the most abundant and others were present as minor components. Of the phospholipids, phosphatidyl ethanolamine, phosphatidyl choline and phosphatidyl serine, and phosphatidyl glycerol were the major components. 6. The major fatty acids in tile total lipids were linoleic(41.6-67.4%), ofeic (14.5-40.7%) and paimitic (7.3-23.3%) acids. The contents of the unsaturated fatty acids were more predominant than saturated fatty acids. 7 .Among the changes of nitrogen compounds, the contents of the soluble protein-N (48.3-65.9%) was the most abundant, whereas insoluble protein-N was slightly higher than soluble protein-N in the hardy orange seed. Peptide protein-N was contained as minor contents (1.8∼4.9%) except citron seed (11.7%). 8. TILe major amino acids of the these seed proteins were glutamic, arginine, aspartic, g1ycine and leucine, and the essential amino acids except tryptophan were detected. 9. It has been identified by SDS-disc electrophoresis that peach seed protein showed 7 bands and the others showed 6 bands. Compared with standard substances, the molfcular weight of the main protein in the gourd, cucumber, peach, citron and hardy orange seeds were estimated to be 44,000, 47, 500, 43,500. 44,500, 46,000 respectively.

A vehicle plate extraction technique is proposed using the intensity transition characteristics of vehicle plate area. A vehicle plate is directly extracted by examining vehicle image from down to up using the domain knowledge. We get 151 real world vehicle images at different time, and test our method with them. In the experimental results, our proposed method shows good performance in spite of the unclear vehicle plate boundary and physically degraded vehicle plate. It shows 98.7% extraction rate, and takes about 1.0 sec to extracte vehicle plate in a vehicle image.

본 논문은 LPC계수의 효율적인 양자화기에 대한 연구로서, LSF 계수의 프레임간 높은 상관도와 예측 에러 신호의 기하학적 성질을 이용한 predictive pyramid vector quantization(PPVQ) 방식을 제안한다. LSF 계수의 예측을 위해 weighted distortion measure를 이용하여 설계한 4차 moving average(MA) 예측기틀 사용하였고, Laplacian 분포를 가지는 예측 에러 신호의 효율적인 양자화를 위해 pyramid VQ(PVQ)를 이용하였다. PPVQ는 적은 계산량으로 23 bits/frame에서 transparent한 성능을 가진다. 또한 PPVQ는 계산량이 적으며 코드북 저장을 위한 메모리를 전혀 필요치 않는다. In this paper, the predictive pyramid VQ(PPVQ) is proposed to quantize LSF parameters. The properties of the LSF parameters, whose prediction error signal is Laplacian and interframe correlation is high, are exploited. To predict the LSF parameters, 4th order moving average (MA) predictor is used, and to quantize the prediction error signal, the pyramid VQ (PVQ) is exploited. It is verified that the performance of PPVQ has the transparent quality at 23 bits/frame. PPVQ requires low complexity and does not need any memories for the codebook storage.
