The mitochondrial genome of domesticated silkworm (Bombyx mori) was mapped with five restriction endonucleases (BamHI, EcoRI, HindIII, PstI and XbaI), the entire genome was cloned with HindIII and EcoRI. From the end sequencing results of 5$^1$and 3$^1$region for full genome set of eleven mitochondrial clones, the seven mitochondrial genes (NADH dehydrogenase 6, ATPase 6, ATPase 8, tRN $A^{Lys}$, tRN $A^{Asp}$, tRN $A^{Thr}$ and tRN $A^{Phe}$ of mori were identified on the basis of their nucleotide sequence homology. The nucleotide composition of NADH dehydrogenase 6 was heavily biased towards adenine and thymine, which accounted for 87.76%. On basis of the sequence similarity with published tRNA genes from six insect species, the tRN $A^{Lys}$, tRN $A^{Asp}$ and tRN $A^{Thr}$ were showed stable canonical clover-leaf tRNA structures with acceptible anticodons. However, both the DHU and T$\psi$C arms of tRN $A^{Phe}$ could not form any stable stem-loop structure. The two overlapping gene pairs (tRN $A^{Lys}$ -tRN $A^{ASP}$ and ATPase8-ATPase6) were found from our sequencing results. The genes are encoded on the same strad. ATPase8 and ATPase6 overlaps (ATGATAA) which are a single example of overlapping events between abutted protein-coding genes are common, and there is evidence that the two proteins are transcribed from a single bicistronic message by initiation at 5$^1$terminal start site for ATPase8 and at an internal start site for ATPase6. Ultimately, this result will provide assistance in designing oligo-nucleotides for PCR amplification, and sequencing the specific mitochondrial genes for phylogenetics of geographic races, genetically improved silkworm strains and wild silkworm (mandarina) which is estimated as ancestal of domesticated silkworm.sticated silkworm.

This experiment was conducted to find out the response of orchardgrass (Dactylis glorneruta L.) varieties to grazing at the condition of monocultures and mixed pastures on the field of Livestock Experiment Station at Suwon from Sep. 1989 to Oct. 1991. The varieties of orchardgrass used in this experiment were Potomac, Hallmark and Syn. No. 2 as a early maturing type, and Lidacta, Rancho and Syn. No. 10 as a late maturing type. The results obtained were as follows: 1. Herbage utilization of mixture with Hallmark variety(T2) was the highest as 78.2% and that with Rancho variety(T5) was the lowest as 70.2%. but there was no difference(P>0.05). Mixtures with early maturing varieties(T1, T2 and T3) were higher as 77.4% than those with late varieties(T4, T5 and T6) as 72.9% in herbage utilization. In monocultures Rancho variety(T5) was the highest as 68.6% and Lidacta variety(T4) was the lowest as 58.8%, and mixtures with early maturing varieties(T1, T2 and T3) as 66.6% were higher than those of late(T1, 72 and 73) as 64.6%. 2. The content of crude protein of 6 mixed pastures ranged from 19.7% to 22.8%, and those of ether extracts, crude fiber, crude ash and nitrogen free extract were 6.6 to 7.5%, 24.9 to 26.2'76, 1 1.5 to 1 1.9% and 33.6-35.4 8, respectively, But there were not different significantly(P>0.05). In monocultures, significant difference by variety was observed in crude protein content(P<0.05). 3. In botanical composition, there was just a little different among 6 mixtures, having 90% or more in grass percentage. The percentages of each orchardgrass varieties were decreased, but those of perennial ryegrasses were increased as grazing sesson was progressed in all treatment.

Present study was carried out to find out an optimum interval for artificial insemination in aged and poor laying hens, Brown colored, hundred and twenty commercial laying hens at about 530 days old and 20 S. C. W. Leghorn males at 580 days old were adopted Egg production rate during the experiment was 61.6% and number of eggs examined was 2,283. The intervals for the insemination were 2, 4 and 6 days for experimental groups T-1, T-2 and T-3, respectively. Eggs were collected on every 6th day and examined for fertility by candling after 5 days of incubation. Average fertility rates for T-1, T-2 and T-3 groups appeared 87.5, 81.1, and 65.1%, respectively. The fertility of T-3 group was significantly lower than those of T-1 and T-2 groups(P＜0.05). The highest fertility rate was obtained on the second day after the insemination for all groups, i. e. 90.7, 84.0 and 71.7% for T-1, T-2 and T-3, respectively. Thereafter, a tendency of gradual decline in fertility was observed. This study suggests that the optimum interval for artificial insemination in aged hens is 2 days. The fertility tended to be improved by repeated injection. For the 2-day interval group, the highest rate (98.2%) was obtained on the 6th insemination.

Purpose : We investigated the relationship between thyroid hormone and serum tumor necrosis factor (TNF-${\alpha}$), interleukin (IL-6) and N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) in patients with Kawasaki disease (KD). Methods : Serum levels of thyroid hormone, TNF-${\alpha}$, IL-6, and NT-proBNP were measured in 52 KD patients in the acute and subacute phase and 10 patients with acute febrile illness (control group). TNF-${\alpha}$ and IL-6 were determined by sandwich enzyme-linked immunosorbent assay (ELISA). Echocardiography was performed to detect coronary artery lesions (CAL) in KD patients. Results : Low $T_3$ syndrome occurred in 63.5% of KD patients. $T_3$ in the acute phase of KD was lower than that in the control. In KD patients, $T_3$ was lowered in the acute phase and elevated in the subacute phase, whereas TNF-${\alpha}$, IL-6 and NT-proBNP were elevated in the acute phase and decreased in the subacute phase. NT-proBNP, and IL-6 were higher in patients with low $T_3$ than in those with normal $T_3$. In addition, $T_3$ inversely correlated with IL-6 and NT-proBNP. Of the 4 patients with CAL, 3 had very low $T_3$. Compared with intravenous immunoglobulin (IVIG)-responsive patients, IVIG-resistant patients had lower $T_3$ and higher IL-6 and NT-proBNP. Conclusion : $T_3$ decreases in the acute phase of KD and normalizes in the subacute phase without thyroid hormone replacement. Low $T_3$ may be partially induced by IL-6 rather than TNF-${\alpha}$, and is strongly associated with high NT-proBNP. $T_3$ in KD may be used for the differential diagnosis, monitoring the activity of the disease, and predicting the severity of inflammation.

This study was conducted to examine the effect of Hwangto, Illite, and any other disease resistant materials as dietary supplements on the growth performance and immunity for growing period with 30 Hanwoo male calves weaned 75days in age. Feeding trial was conducted with 6 treatments(five heads/treatment), which were T1(Control), T2(Control + 2% Hwangto), T3(Control + 2% Illite), T4(Control + 0.04% Oligosacharides), T5(Control + 2% Charcoal powder) and T6(Control + 0.1% Chromium picolinate) for 120 days from three to seven months in age. The results obtained are summarized as follows; During the experimental period, average daily gains were 0.82 to 0.92kg, and were high in the order of T3, T6, T4, T5, T2 and T1. Especially the growth rate of calves for growing period was higher in Illite, chromium-picolinate and oligo- sacharides feeding groups than in any other groups. Average daily intakes and intake ratio to body weight of concentrates for 120days were 3.91 to 4.15kg(average 4.03kg) and 3.10 to 3.31% (average 3.21%), respectively. TDN intakes per kilogram gains were 3.20 to 3.57kg(average 3.35kg) and were smaller in the order of T5, T3, T6, T4, T2 and T1, respectively. Density of IgG in serum of calves measured by the IgG SDID Kit was 10.2 to 11.6mg/$m\ell$, and especially increase rate of IgG for experimental period was high in T3 and T5 by 6.9 and 2.8%, respectively. But incidence of disease was not found to be different by treatments. According to the above results it may be concluded that Illite is a sort of clay minerals increased the growth rate, feed efficiency and immunity of early weaned calves for growing period, but was not in unprocessed Hwangto.

The effects of heat treatments (T6 and T73) on the microstructure, mechanical properties, and high cycle fatigue behavior of modified AA7075 alloys were investigated. A modified 7075 alloy was manufactured using modified-Mg (Mg-Al2Ca) instead of the conventional element Mg. Based on the microstructure, the average grain size was 4.5 ㎛ (T6) and 5.2 ㎛ (T73). Regardless of heat treatment, the modified AA7075 alloys consisted of Al matrix containing homogeneously distributed Al2CuMg and MgZn2 phases with reduced Fe-intermetallic compound. Room temperature tensile tests showed that the properties of modified 7075-T6 (Y.S.: 622MPa, T.S: 675MPa, elongation: 15.4%) were superior to those of T73 alloy (Y.S.: 492MPa, T.S: 548MPa, elongation: 12.8%). Experimental data show that the fatigue life of T6 was 400 MPa, about 64% of its yield strength. However, the fatigue life of T73 alloy was 330 MPa and 67%. Irrespective of the stress level, all crack initiation points were located on the specimen surface, and no inclusions acting as stress concentrators were seen. Superior mechanical properties and high cycle fatigue behavior of modified AA7075-T6 alloy are attributed to the fine grains and homogeneous distribution of small second phases such as MgZn2 and Al2CuMg, in addition to reduced Fe-intermetallic compounds.

This study was carried out to investigate the effects of seeding dates and cultivated period on the growth characteristics, dry matter yield and feed value of Teosinte new variety "Geukdong 6"[Zea mays L. subsp. mexicana (Schrad.) H. H. Iltis]for feed. The experimental design was arranged in a randomized block design with three replications. Treatments consisted of five time seeding dates, 10 May(T1), 25 May(T2), 10 June(T3), 25 June(T4) and 10 July(T5), and same time harvesting, 22 October. Therefore, growing period were 164 days(T1), 149 days(T2), 134 days(T3), 119 days(T4) and 103 days(T5), respectively. In growth stage at harvest time, T1, T2, T3, T4 and T5 were early flowering, end heading, middle heading, early heading and early heading stage, respectively. Plant length and dead leaf were highest in T1, but leaf width and number of leaf were highest in T2 than others (p<0.05). Leaf length, stem diameter and number of tiller were not significantly different among the treatments (p<0.05). Stem hardness was higher in order of T1(2.0)> T2(1.9) > T3=T4(1.7) > T5($1.2kg/cm^2$). Fresh yield and dry matter yield showed significantly higher as the sowing time was faster and the cultivation period was longer (T1 > T2 > T3 > T4 > T5, p<0.05). Crude protein, crude fat and TDN content were highest in T5, but ADF and NDF content were highest in T1 than others (p<0.05). T1, T2 and T3 showed significantly higher crude protein yield compared to T4 and T5 (p<0.05). Total digestible nutrients yield were higher in order of T1 > T2 > T3 > T4 > T5 (p<0.05), and relative feed value were higher in order of T5 > T4 > T3 > T2 > T1 (p<0.05). Based on the above results, seeding dates could be recommended from the early May to the late May, and it is efficient that the cultivation period is over 150 days for dry matter yield, crude protein yield and total digestible nutrients yield.

This study was carried out to determine the optimum harvest stage of Italian ryegrass (Lolium multiflorum Lam., IRG) for maximum forage production during the spring season in Suwon, 2010. The variety of IRG was the early maturity type, 'Kowinearly', and six harvest stages (treatments) were first heading (T1), heading (T2), late heading to early bloom (T3), bloom to late bloom (T4), ripeness (T5), and late ripeness stage (T6). The dates of the first heading and heading of 'Kowinearly' were seen on 4 to 5 May, and 14 May, respectively. Plant length and dry matter (DM) percentage at first harvest were from 69 cm and 14.8% at T1 stage to 103 cm and 35.0% at T6 stage, respectively. The content of crude protein (CP) and in vitro DM digestibility (IVDMD) of T1, T2, T3, T4, T5 and T6 at first harvest were 15.6%, 10.6%, 10.1%, 8.1%, 7.3% and 5.4%, and 81.8%, 72.1%, 64.8%, 63.8%, 61.4% and 59.0%, respectively. The content of neural detergent fiber (NDF) and acid detergent fiber (ADF) were increased continuously with delayed harvest. A significantly higher yield of DM, CP and in vitro digestible DM (IVDDM) were observed for T3, and T4 (p<0.05). DM yield of 3,526 kg, 6,278 kg, 7,842 kg, 8,984 kg, 8,346 kg and 8,008 kg/ha, CP yield of 549 kg, 665 kg, 795 kg, 725 kg, 608 kg and 430 kg/ha, and IVDDM of 2,883 kg. 4,526 kg, 5,083 kg, 5,728 kg, 5,124 kg and 4,722 kg/ha at first harvest were recorded in T1, T2, T3, T4, T5 and T6, respectively. Regrowth yield of DM, CP and IVDDM were shown to be higher at T1 and T2 (p<0.05). However, no significant differences were observed between the two stages. Daily DM and DDM production of regrowth IRG were higher at T2, followed by T1. The total yield (at first and at regrowth) of DM, CP and IVDDM were significant higher for T2, followed by T3, T4 and T1 in order. At T2 stage, the yield was 11,089 kg, 1,254 kg, and 7,669 kg/ha in DM, CP, and IVDDM. In conclusion, the late heading to bloom stage was determined to be the optimum harvest stage for a single harvest, while the heading stage was a suitable stage of first harvest of 'Kowinearly' where two harvests were sought in a single year.
