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.

생선회용 해산물에 오염되어, 생식한 경우 발생되는 패혈병의 원인균주인 Vibrio vulnificus의 생육 및 독성생성을 억제할 목적으로 천연 항균제인 Grapefruit종자추출물(GPSE)을 이용하여 그 항균효과를 검토하였다. In vitro 시험결과, Vibrio vulnificus에 대한 GFSE의 생육최소저해농도는 50~100 ppm 정도이었으며, Vibrio vulnificus 균체세포틀 100 ppm 농도의 GFSE 용액으로 처리하고 전자현미경 촬영시료로 조제하여 촬영한 후, 미생물형태을 무처리대조구와 비교, 검토한 결과, GFSE 처리로 세포막 기능이 파괴되어 세포내용물이 균체외부로 유출되어 균체의 생육이 억제되고 균체내부가 빈 ghost 형태의 균체수가 증대되어 GFSE의 항균효과를 확인할 수 있었다. 한편, 생선회용 해산물에 GFSE를 근육주사하고 Vibrio vulnificus를 접종한 수조내에서 사육하여 채취한 어육부를 마쇄하여 일정량씩을 표준사료에 첨가해서 통닭용 병아리를 실험동물로 하여 사양실험을 실시한 결과. 체중증가율, 단백질이용효율, 혈청내 효소활성, 혈청의 주요성분함량 등에 있어서, GFSE 처리수조내에서 사육한 해산물을 첨가한 시료시험구의 경우, 무첨가사료처리구와 비교할 때 뚜렷한 차이를 목격할 수 없었으며, GFSE 첨가에 따른 실험동물의 성장저해 또는 독성현상을 유발하지 않음을 알 수 있었다. 아울러, 각 처리구에서 사양한 해산물의 어육부에 오염된 Vibrio vulnificus의 균수를 측정한 결과, 250ppm 이상의 GFSE 처리구에서는 Vibrio vulnificus를 전혀 검출할 수 없었다. To prevent food-poisoning outbreaks by Vibrio vulnificus the antimicrobial efficacy of grapefruit seed extract (GFSE) was examined. Minimal inhibitory concentration (in vitro) for the microorganism was found to be 50~100 ppm. Transmission electron micrographs of Vibrio vulnificus showed the biocidal action of this natural antimicrobial agent would be related to specific respiratory effect coupled with the destruction of permeable function of microbial cell membrane. After Anguilla japonia GFSE-injected to the body was incubated in the seawater contaminated by Vibrio vulnficus the fish meats were taken up, mixed with control diet and used as a diet in the feeding experiment. In this experiment the effect of GFSE treated with fish muscle on body weight protein efficiency ratio, serum enzymes and serum blood component of broiler chicks was investigated. It is proved from this study that there is neither Vibriosis nor toxicity associated with GFSE itself and fish meats treated with it when it is injected to the fish body at a level of 250 ppm or less.

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.

연속 추출장치를 이용하여 grapefruit 종자를 gl-ycerine으로 추출하고 농축, 조제한 grapefruit 종자추출물(GFSE)의 항균 및, 항산화성 효과를 검토하기 위하여 정어리, 고등어 및 새우와 같은 수산물을 재료로 하여 GFSE를 처리하지 않은 대조구와 GFSE용액 (100, 250, 500, 750, 1,000PPM)으로 처리한 시험구로 나누어 Salmonella tylhi를 접종하여 일정 온도에서 저장하면서 총균수, 과산화물가 및 texture의 변화를 측정하고 GFSE처리후 저장한 수산물을 대조구와 외관, 냄새를 중심으로 관능검사를 실시하였다. 정어리와 고등어의 경우, 최초 균수가 1.9*10^6, 1.8*10^6이었는데 500PPM 농도 첨가하여 5℃에서 50일 저장후 1.1*10^4과 9.0*10^3으로 감소되었고, 새우의 경우 균의 검출이 확인되지 않아 상당히 좋은 항균효과를 나타내었다. 그리고, 3종의 수산물 모두 GFSE처리구가 대조구에 비하여 유의적인 항산화효과가 있음을 나타내었으며, 500~750PPM 농도의 용액을 처리하여 30℃에서 30일간 저장한 수산시료 추출유의 과산화물가는 정어리는 최초 28~45meq/kgdptj 92~143meq/kg(대조구,490meq/kg)로, 고등어는 64~75meq/kg에서 98~137meq/kg(대조구, 406meq/kg)로, 새우는12~20meq/kg에서 21~32meq/kg(대조구, 72meq/kg)로 증가하여 뚜렷한 산패 억제효과를 볼 수 있었다. Texture도 저장기간이 경과함에 따라 감소하는 경향을 나타내었으나 3종 수산물 모두 GFSE용액 처리시험구에서 감소율이 크게 낮아졌다. GFSE를 처리하여 0℃, 0일간 보관한 시험구와 대조구에 관한 관능검사 결과, GFSE를 처리하지 않은 대조구는 열등한 기호도를 보여준 반면, GFSE용액을 500PPM 이상의 농도로 처리한 시험구 모두가 높은 기호도의 관능검사 결관를 나타내었다. The antimicrobial and antioxidant activities of grapefruit seed extract(GFSE), which was extracted with glycerine in the special schematic extraction apparatus, were investigated for handling and processing of fishery products. The effectivity of GFSE has been tried on sardine, mackerel and shrimp divided into six lots for each fishery product: control(no treatment) and five GFSE-treated samples. Samples were inoculated with Salmonella typhi, incubated for 24hrs at 30℃ in dextrose-tryptone broth medium and prepared for microbiological & chemical analysis and organoleptic assessment. The bacteriological analytical results with GFSE(250ppm) showed the reduction of 1.8×10^6→2.0×10^4, 1.9×10^6→1.8×10^4 and 1.6×10^6→2.7×10^3 in total bacterial count for sardine, mackerel and shrimp, respectively. The test results with GFSE(500ppm) showed a 100% reduction of bacterial mackerel treated with GFSE(500ppm) was reduced to 1.1×10^4 and 9.0×10^3 respectively. Antioxidant effect of treatment with GFSE at 500ppm level for three products was significant. LSD test results on organoleptic parameter for the samples treated with various showed a significant influence on the appearance, odor and texture in which at concentration 500ppm level give the excellent scours compared to each control.

The purpose of present study was to evaluate the bioequivalence of two enalapril maleate tablets, Renitec^(™) (MSD Korea Ltd.) and Enalace ^(™) (Welfide Korea Ltd.), according to the guidelines of Korea Food Drug Administration (KFDA). Twenty-four normal male volunteers, 22.33±2.55 year in age and 66.54±8.30 ㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After two tablets containint 10 ㎎ of enal-april maleate per tablet wre orally administered, blood was taken at predetermined time intervals and concentrations of enalapril in plasma were determined using LC-MS-MS. Pharmacokinetic parameters such as AUC_(t), C_(max) and T_(max) were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed AUC_(t) and C_(max) untransformed T_(max). There were no sequence effects between two formulations in these parameters. The 90% confidence intervals for the log transfored data were acceptance range of log0.8 to log1.25(e.g., log1.02∼log1.14 and log1.03∼log1.19 for AUC_(t) and C_(max), respectively). The major parameters, AUC_(t) and C_(max), met the criteria of KDFA for bioequivalence indicating that Enalace^(™) tablet is bioequivalent to Renitec^(™) tablet.
