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.

The values of RBC count, Hb content, PCV, MCH and MCHC increased up to 15-20kg milk yielding group and thereafter they tended to decrease with higher milk yielding groups. In other words, there was a negative correlation between the values of erythrocytic series and milk production. 24. The leukocyte and lymphocyte count were a negative correlation with milk yield, while the neutrophil count was a positive correlation wirh milk yield. The monocyte and eosinophil count tended to increase as milk production increased. No relationships were found between the platelet count and milk production. 25.

Effect of Pair-Mineralizer on the Reaction of Alite and Calcium Langbeinite Formation

Kwon, Woo Teck,Kim, Young Phil,Kim, Y.,Kim, Soo Ryong,Bae, Seong Youl Trans Tech Publications, Ltd. 2006 Materials science forum Vol.510 No.-

<P>This paper investigates the effect of the pair-minerializer (CaSO4,-CaF2) on the reaction of alite, belite and calcium langbeinite formation with different alkali and sulfate contents. A set of clinker samples was prepared by adding laboratory grade reagents of (NH4)2SO4, CaF2 and K2CO3 to the cement raw mixes. The mineralogical composition of clinker was analyzed by X-ray powder diffraction, and the quantity of minerals was evaluated by using TOPAS software. As the experimental results, the total amount of calcium silicate minerals was rapidly increased with the addition of F and SO3 components simultaneously as pair-mineralizer with K2O more than the value which mineralizer was added separately. Also, in the case of adding K2O only to the raw mixes, the amount of alite is decreased after clinkering. However, if alkali (K2O) and pair-minerializer (CaSO4,-CaF2) were added simultaneously, the quantity of alite and calcium langbeinite mineral increased because of the formation of stable clinker minerals by the reaction of alkali (K2O) and sulfate.</P>

Kwon, Woo Teck,Kim, Soo Ryong,Kim, Y.,Lee, Yoon Joo,Won, Ji Yeon,Ko, Tae Gyung,Oh, Sea Cheon Trans Tech Publications, Ltd. 2013 Materials science forum Vol.761 No.-

<P>Characterization of silicon kerf from photovoltaic silicon-wafer production was carried out. Also, SiC powder was synthesized using high purity silicon kerf by varying grinding conditions. With increase of grinding time, surface of the silicon was oxidized to form silicon oxide. Also, it was observed that the unreacted silicon oxide and free silicon amount in the SiC powder increases with an increasing grinding times, even though silicon particle size of the starting material is decreased.</P>

<P>In an environmental and economic point of view, recycling of silicon wafer sludge is important. The aim of this work is to investigate the recycling method of silicon wafer sludge. Therefore, drying rate of silicon wafer sludge has been studied for separation of liquid and solid from sludge. Silicon and silicon carbide powder obtained from silicon wafer sludge were analyzed by SEM, XFR, XRD and particle size analyzer. The recovered oil was also characterized using GC-MS. From this work, it can be seen that the falling drying rate of silicon wafer sludge is linear equation.

<P>Polyphenylcarbosilane (PPCS) was synthesized from thermal rearrangement of the polymethylphenylsilane around 350 ~ 430°C. Characterization of synthesized PPCS was performed with FT-IR spectroscopy analysis. From FT-IR data, the band at 1035cm<SUP>-1</SUP> is very strong and assigned to CH2 bending vibration in Si-CH2-Si group, indicating the formation of the PPCS. Ceramic thin film was fabricated onto stainless substrate by dip coating using a 20wt% PPCS in toluene. Heat treatment of the samples was performed at various temperatures (600°C and 800°C) under nitrogen atmospheres. The prepared PPCS samples and the coating layers on SUS316 after heat treatment were analyzed using FT-IR and XPS, respectively.</P>

<P>In our study, the dielectric properties of SiOC low k thin film derived from polyphenylcarbosilane were investigated as a potential interlayer dielectrics for Cu interconnect technology. A SiOC low k thin film was fabricated onto a n-type silicon wafer by dip coating using 30wt % polyphenylcarbosilane in cyclohexane. Curing of the film was performed in air at 300°C for 2h. The thickness of the film ranges from 1 μm to 1.7 μm. The dielectric constant was determined from the capacitance data obtained from metal/polyphenylcarbosilane/conductive Si MIM capacitors and shows a dielectric constant as low as 3.26 without porosity added. The SiOC low k thin film derived from polyphenylcarbosilane shows promising application as an interlayer dielectrics for Cu interconnect technology.</P>
