        In this paper, we proposed a technique for minimizing blocking effects and mosquito noises which are major causes of image degradation in H.263-based transmitted images. Since the blocking effects occur in the uniform region like background and the mosquito noises occur in the non-uniform rigion like edge neighborhood, we proposed an algorithm to divide image into uniform and non-uniform regions and a filtering algorithm that is adequate for each noise. To reduce the blocking effects, 4-pixel non-linear filter is proposed to get the better performance in both subjetive and objective respect. 5-pixel median filter is used for reducing mosquito noises. In simulation result, the proposed method shows higher PSNR of 0.02~1.01dB and better subjective test, results in comparison with existing methods.

      • Modular Intermeshing Co-rotating Twin Screw Extruder 내에서 제조된 PC/ABS 블랜드의 물리적, 유변학적 성질

        방대석,정우형 금오공과대학교 2006 論文集 Vol.27 No.-

        The physical properties and melt behavior of PC/ABS blends may be significantly affected by mixing equipments and processing conditions. In this study, the physical and rheological properties of PC/ABS blends in a modular interrneshing co-rotating twin screw extruder were investigated. PC and ABS were blended by different conditions such as different compositions of PC and ABS, and the several types of screw configurations in a modular interrneshing co-rotating twin screw extruder. After extrusion, the specimens were fabricated by injection molding. Then the physical properties were measured by tensile and Izod-irrpact tests. The melt behavior was observed with the capillary rheometer. Mixing and melting behaviors in the extruder were investigated by the cooling experiment for the different screw configurations.

        牛와 緬羊 그리고 山羊의 hemoglobin phenotype 및 遺傅子의 出現頻度를 檢討하고자 牛 460頭(韓牛 430, Holstein 30), 緬羊 214頭(Corriedale 140 Polworth 74), 山羊 150頭(在來山羊 黑色種 60, 在來山羊 白色種 40, Saanen 雜種 50)에 對하여 寒天 gel 電氣泳動法을 實施하여 다음과 같은 結果를 얻었다. 1. 牛의 hemoglobin phenotype는 HbAA, HbAB, HbBB, HbAC 그리고 HbAD의 5型으로 나타났으며 이들의 出現頻度는 HbAA型이 78.70%, HbAB型이 20.00%, HbBB型이 0.43%, HbAC型이 0.43%, 그리고 HbAD型이 0.43%이었다. hemoglobin型, 支配遺傅子은 ??, ??, ?? 그리고 ??의 4種으로 그 出現頻度는 ??가 89.13%이고 ??가 10.43%이며 ??와 ??는 名名 0.22%이었다. 단지 Holstein種은 hemoglobin phenotype가 HbAA型과 HbAB型만이 나타났으며 그 出現頻度는 HbAA型86.67%이고 HbAB型이 13.33%이었다. Holstein種의 hemoglobin 支配遺傅子는 ??와 ??의 2種으로 그 出現頻度는 ??가 93/33%이었고 ??가 6.67%이었다. 2. 緬羊의 hemoglobin phenotype는 HbAA, HbAB 그리고 HbBB의 3型으로 나타났으며 이들의 出現頻度는 HbAA型이 63.08%, HbAB型이 29.91% 그리고 HbBB型이 7.01%이었다. hemoglobin型 支配遺傅子는 ??와 ??의 2種으로 그 出現頻度는 ??가 78.04%이었고 ??가 21.96%이었다. Carriedale種과 Polworth種과는 hemoglobin型에는 差異가 없었으나 型의 出現頻度와 그 支配遺傅子의 出現頻度에는 큰 差가 있었다. 즉 Corriedale種는 hemoglobin phenotype의 出現頻度가 HbAA型이 80.71%이며 ??의 出現頻度는 89.64%나 되었으나 Polworth의 hemoglobin phenotype의 出現頻度는 HbAA型이 29.73%이며 HbAB型이 52.70%로 가장 많았으며 ??의 出現頻度가 43.92%나 되었다. 3. 山羊의 hemoglobin phenotype는 全部 同一型으로 나타났으며 牛나 緬羊의 HbAA型에 類似하였다. The hemoglobin phenotypes and the gene frequencies of 460 cattle(430 Korean native cattle, 30 Holstein), 214 sheep(140 Corriedale, 74 Polworth) and 150 goats(60 black Korean native goats, 40 white Korean native goats, 50 Saanen hybrid) were examined by agar gel electrophoresis. The results obtained were as follows; 1. In cattle hemoglobin phenotypes, HbAA, HbAB, HbBB, HbAC and HbAD were observed and their frequencies of appearence were 78.70, 20.00, 0.43, 0.43, and 0.43 per cent respectively. The distribution of gene frequency were calculated 89.13 in ??, 10.43 in ??, 0.22 in ?? and 0.22 per cent in ??. Among the cattle hemoglobin phenotypes two hemoglobin types, HbAA and HbAB, were observed in Holstein and their frequencies of appearence were 86.67 and 13.33 per cent respectively. The distribution of gene frequency were calculated 93.33 in Hb?? and 6.67 per cent in ??. 2. In sheep hemoglobin phenotypes, HbAA, HbAB and HbBB were observed and their frequencies of appearence were 63.08, 29.91 and 7.01 per cent respectively. The distribution of gene frequency were calculated 78.04 in ?? and 21.96 per cent in ??. The distribution of gene frequency of Hb?? was 89.64 per cent in Corriedale but 56.08 per cent in Polworth. 3. Only one hemoglobin type was found in the goats and the type was similar to the HbAA type which was showed in cattle and sheep.

        , In order to get the normal blood values of Holstein calves and heifers in Korea, blood samples were taken from 180(♀123, ♂57) healthy calves and heifers Chonnam province. The results obtained in the present study are as follows: 1. Determined average red blood cell count was 5.61(4.00∼9.96)×10??/㎕, whereas average red blood cell count obtained from the results in the normal range(normal) was 6.19(5.08∼9.23)×10??/㎕. The red blood cell count appeared to decrease with age. 2. Determined average hemoglobin content was 10.40(6.5∼15.3)g/100㎖, whereas normal hemoglobin content was 11.20(9.3∼14.4)g/100㎖. The hemoglobin content tended to decrease with age. 3. Determined average packed cell volume(PCV)was 31.43(22∼46)㎖/100㎖, while normal PCV was 33.75(28∼43)㎖/100㎖. The PCV tended to decrease with age. 4. Determined mean corpuscular volume(MCV) was 56.02(35.71∼70.00) fl. Normal MCV was 54.52(42.25∼61.87) fl, which was lower than the determined MCV. 5. Determined mean corpuscular hemoglobin concentration(MCH) was 18.54(12.35∼24.00) pg. Normal MCH was 18.09(14.01∼20.58) pg, which was lower than the determined MCH. 6. Determined mean corpuscular hemoglobin concentration(MCHC) was 33.09(24.21∼40.83)g/100㎖. Normal MCHC was 33.19(28.33∼36.33)g/100㎖, which was higher than the determined MCHC. 7. Determined average white blood cell(WBC) count was 9,681(3,590∼18, 630)/㎕ whereas normal WBC count was 9,104(4,780∼13,184)/㎕. The WBC count tended to increase with age. 8. In the normal WBC differential count, the values were lymphocyte 67.83(44∼86)%, monocyte 2.63(0∼8)%, neutrophil 26.57(8∼53)%, eosinophil 2.48(0∼9)% and basophil 0.49(0∼2)%, respectively. No differences were found between the determined and normal values. 9. Lymphocyte count appeared to increase with age, while the reverse was the case with neutrophil count. 10. Determined average platelet count was 261,981(119,000∼964,000)/㎕, whereas normal platelet count was 283,064(135,000∼964,000)/㎕, which was slightly higher than the determined platelet count. The platelet count between age groups appeared to be higher in the age groups of 1 day to 1 month and 2 months to 3 months than the other age groups.

        Trametes versicolor에 의한 상수리나무의 분해형태

        유태방,윤민호,최우영,이종신 충남대학교 농업과학연구소 2001 농업과학연구 Vol.28 No.2

        백색부후균 Trametes versicolor(CV5) 균주에 의한 wood lignin의 분해능을 조사하였다. CV5는 활엽수와 침엽수에 속하는 여러 수종의 프로토 리그닌 분해 시 활엽수에 한해서 분해되는 특성을 보였으며, 특히 상수리나무에서 33.5%의 가장 높은 리그닌이 분해되었다. 리그닌 분해에 관련된 phenoloxidase 분비능을 Bavendamm 시험을 통해 검토한 결과 CV5는 지금까지 연구된 우수 백색 부후균과 같은 유사 반응 형태를 나타내고 있음을 확인하였다. 또한 상수리 목재 chip표면에 CV5의 균사가 생육하면서 목재조직이 부후된 상태를 주사전자 현미경으로 관찰한 결과 목섬유 및 도관에서 균사의 침투와 목재조직의 분해를 확인하고 리그닌에 대한 높은 선택적 분해력을 갖고 있음을 구명하였다. Trametes versicolor(CV5) selected as a white-rot fungus with strong lignin degrading activity, in the previous paper, was investigated on a properties of degradation of wood lignin. Lignins of hardwoods, especially oak(Querous acutissima carruth) an paulownia (Paulownia coreana Uyeki) were considerably delignified by the CV5, however, softwoods used in this experiment were not delignified. Bavendamm's reaction was positive with several phenols on agar plates for the confirmation of a phenoloxidase secreted Through the morphologies of decayed wood chip observed with the aid of scanning electron microscopy, it was found that the hypha of CV5 penetrated the ray cells and vessels caused separation of the wood cellulose.
