  • The present study analysed the various productive and reproductive characteristics of 1/2 Pabna Milking Cows (PMC)-1/2 Sahiwal (S) and 1/4 PMC-3/4 S collected from the Pabna milkshed area at Baghabarighat, Sirajgonj, Bangladesh. The studied traits were birth weight (BWT), age at puberty (AP), number of services per conception (NSC), post partum heat period (PPHP), gestation period (GP), daily milk yield (DMY), lactational production (LP), lactation length (LL), fat percentage and solids-not-fat percentage (SNFP). Five individual Sahiwal sires were used for the upgrading of Pabna Milking Cows. The used data covered from 1987 to 1994. Least-squares analysis of variance showed that genetic group had a significant effect on BWT (P < 0.05), AP (p < 0.01), DMY (p < 0.01), LP (p < 0.001), LL (p < 0.05), FP (p < 0.05) and SNFP (p < 0.01). Genetic group had non-significant effect on NSC, GP and PPHP. The effect of sire was significant on BWT (p < 0.01), NSC (p < 0.01), LP (p < 0.05) and LL (p < 0.05). The AP, NSC, DMY, LP, LL and SNFP were higher in 1/2 PMC-1/2S cows; BWT and PPHP were higher in 1/4 PMC-3/4S but GP and FP were almost same in both genetic groups. From this study it may be concluded that production and use of 1/2 PMC-1/2S would seem more profitable for commercial milk production in the Bangladesh Milk Producers' Cooperative Union Limited (BMPCUL) area and at the same time emphasis should be given on rigorous sire selection.

  • In this paper, digital watermarking method using quad-tree algorithm is proposed. The proposed algorithm searches the significant coefficient of the watermark by using quad-tree algorithm and inserts the watermark by the Cox's algorithm. The simulation for performance analysis of the proposed algorithm is implemented about the effect of quad-tree algorithm in wavelet domain and that of embedding watermark in each subband coefficient (HH, LH, HL) and each DWT level, and that of embedding in the lowest frequency band (LL). As a simulation result, digital watermarking using quad-tree algorithm improves the watermarking performance in comparison with inserting watermark in the significant coefficients of fixed frequency band. The watermarking performance of simultaneously embedding in HH, LH, and HL band of DWT(6 level) is better than that of different cases. In addition, insertion the watermark to the LL band about 30~60% of all watermarks improves the correlation value while PSNR performance decreases 1~3dB.

  • A series of New N-[1-(benzotriazol-1-yl)-X-substituted benzyl]-Y-substituted aniline derivaties (S) have been synthesized. And the rate of hydrolysis was investigated kinetically in 25% (v/v) aqueous methanol at 25$^{\circ}C$. On the basis of rate equations, solvent effect $m {\ll} 1,\; n \leq 3\; and\; m {\ll} l$), salt effect, general base catalysis, substituent effect (${\rho}_{xy}$ > > 0), and hydrolysis products analysis, it may be concluded that the hydrolysis of N-[1-(benzotriazol-1-yl)benzyl]aniline proceeds the "A-$S_N2$" mechanism below pH 12.0, while above pH 13.0, the hydrolysis proceeds through a typical "$S_N2$" mechanism.

  • This study aims to describe actual condition of residents' involvement of Sk$\"{a}$rk$\"{a}$ll ecovillage in Sweden by in-depth interviews with five residents. This study, hopefully, could contribute to offer useful information for forming ecovillage, as well as awakening about ecovillage movement to the public in Korea. The interviews were fulfilled during spring of 2010 in G$\"{o}$teborg and Sk$\"{a}$rk$\"{a}$ll ecovillage in Sweden. The results are as follows: 1) In terms of overall residents' involvement by self-evaluation everybody agrees with that residents' involvement was quite excellent during forming stage of the village, while it has been notably decreased now in running stage. It reveals there is a gap between ideology and reality. 2) Concerning decision making method, they use majority decision instead of consensus, since only 9 households of 20 are residing there all year around, it is hardly possible to assemble all the residents in the meeting. In Accordance with problematic conflicts in the village recently, development of socialization with others and education of communication skill for residents probably could be helpful to resolve conflicts among residents in long term. 3) In terms of evaluation of ecovillage movement in Sk$\"{a}$rk$\"{a}$ll ecovillage, it is the fact that many residents live less self-sufficiently, more energy consumed than the ideology pursuits. Also, they live with close connections with conventional society. Nevertheless, the efforts they are willing to practice 3R principles (Recycle, Reuse, Reduction) have to be highly respected, if we consider its educational influence to environmental movement for the conventional society.

  • The study was conducted to know the differential growth responses of soybean cultivars as affected by various application stages of Metribuzin herbicide, at the University experimental farm of Chonnam Nat'l. Univ, Kwangjoo, 1980. Experimented soybean materials were six cultivars, as Kwanggyo, Dongbuktae, Bongui, Yukwoo 3, Suweon 85, and Suweon 86., . and Laid-out application stages were five as pre-sowing, Pre-emergence, Early Post-emergence, and Late Post-emergence treatment comparing with Control. Results obtained from the study were as follows: Among experimented soybean cultivars, no significantly tolerant cultivar was shown. Highly significant differences in phytotoxicities by Metribuzin treatments were detected among various application stages, and crop tolerances were recognized bigger in order as E. Post-emg. < L. Post-emg. $\ll$ Pre-emg. < Pre-sowing $\leq$ Control. The phytotoxic symptoms of all soybean cuitivars were severely recorded in order of Leaf No. /Plant < Plant height $\ll$ Branch No. /Plant. For the cultivation of most soybean cuitivars, the use of Metribuzin in Pre-sowing or Pre-emergence were recommended, and especially it is expected to follow of more detailed study on soil-incorporation method in Pre-sowing treatment, and rather the tank-mixture system of Metribuzin with others than the mono-application system for the safe-use and enlargement of weeding-spectrum.

  • Yingchuang yicao(${\ll}$螢窗異草${\gg}$) is a collection of short stories in Classical Chinese, whose style was much affected by Liaozhai zhiyi(${\ll}$聊齋志異${\gg}$). It consists of 3 chapters, 12 juan, and 138 stories. This work was written by a scholar with the pen name of Hao gezi(浩歌子) in the reign period of Qianlong in the Qing dynasty, and has drawn relatively little attention among the scholars thus far; it was not until 1980's that scholars figured out that the author Hao gezi was Yin Qinglan, the sixth son of the renowned Qing scholar Yin Jishan. Yingchaung yicao had circulated as a manuscript for more than one hundred years until it was printed by Shenbao guan(申報館) in Shanghai in the reign period of Guangxu 2-3 (1876-1877). This edition is currently collected at The Kyujanggan(奎章閣) Institute of National Seoul University. At present, no known study of its introduction to and circulation in premodern Korea is available. However, given that the late $Chos{\ddot{o}}n$ period saw high interest in Chinese narratives, it is speculated that this work was imported to Korea soon after its first publication in China. Later, two publishing houses in Shanghai also published illustrated editions of the work. Given that the Shenbao guan version is the first printed edition of Yingchuang yicao, the copy collected at Kyujanggak Institute should be regarded highly for its academic values.

  • Steers (n = 335) of known genetic backgrounds from four fundamentally different growth types were subjected to two production systems to study the main effects and possible interactive effects on carcass composition. Growth types were animals with genetic potential for large mature weight (LL), intermediate mature weight-late maturing (IL), intermediate mature weight-early maturing (IE), and small mature weight-early maturing (SE). Each year, in a nine year study, calves of each growth type were weaned and five steers of each growth type were developed on pasture or feedlot and harvested at approximately 20 and 14 mo of age, respectively. Data recorded were chilled carcass weight and percentages of forequarter, foreshank, chuck, rib, plate, brisket, hindquarter, round, rump, shortloin, sirloin, flank, lean, fat, bone, and retail cuts. The growth $type{\times}production$ system interaction was an important source of variation in chilled carcass weight (p = 0.0395) and percentage retail cuts (p = 0.001), lean (p = 0.001), fat (p = 0.001), rump (p = 0.0454), shortloin (p = 0.0487), and flank (p = 0.001). The ranking of the growth $type{\times}production$ system means for percentage lean was LL-pasture>IL-pasture = IE-pasture = SE-pasture>LL-feedlot, IL-feedlot>IE-feedlot = SE-feedlot. The growth $type{\times}production$ system interaction was non-significant (p>0.05) for forequarter, foreshank, chuck, rib, plate, brisket, hindquarter, round and bone. Growth types of IE and SE yielded greater (p<0.05) mean forequarter than did growth types of IL and LL ($51.6{\pm}0.3$ and $51.5{\pm}0.3$ vs. $51.1{\pm}0.3$ and $50.8{\pm}0.3%$). Mean bone was highest (p<0.05) for the LL growth type and lowest (p<0.05) for the SE growth type ($19.5{\pm}0.5$ vs. $16.8{\pm}0.5%$). Mean bone was greater (p<0.05) for the pastured steers than for the feedlot steers ($21.8{\pm}0.8$ vs. $14.5{\pm}0.6%$). These data indicate that growth type responded differently in the two production systems and that these results should be helpful in the match of genetics to production resources.

  • In this paper, using third-order system of the PLL we'll analyze the aspect of flicker noise appearing troubles in the low frequency band. Since it is difficult to analyze mathematically flicker noise in the third-order system of the PLL, introducing the concept of pseudo-damping factor using the optimized second-filter has made an ease of the access of the flicker-noise variance. we'll show a numerical formula of flicker variance in the third-order system of the PLL which is compared with that of 1/f noise variance in the second-order system of the PLL.

  • Twenty college women were led experimental diet which composed ot basal diet plus different kinds of dietary rats at 27% Cal. Equal amount of 13.5g of corn oil, perilla oil or fish oil was supplied for 2 weeks as a source of n6 linoleic acid(LA). n3 $\alpha$-linolenic acid (LL). or n3 EPA + DHA. respectively. Plasma total Chol level was reduced by perilla and fish oils, significantly only by fish oil. Plasma Chol level was rather increased by corn oil(P<0.05), but was decreased by double amount of corn oil supplement. Therefore, hypocholesterolemic effect of fatty acids was in the order of n3 EPA+DHA>n3 LL>n6 LA and influenced by the degree of fat unsaturation. Plasma TG level was also significantly decreased by n3 EPA+ DHA and increased by n6 LA. Hypotriglyceridemic effect of fatty acids was also in the order of n3 EPA + DHA> n3 LL>n6 LA and influenced by the unsaturation. However, the reduction of plasma TG was more influenced by the fatty acid structure rather than the fat unsaturation. There were no significant effects on lipoprotein pattern 3nd chemical compositions of lipoprotein by different dietary PUFAs. but fish oil diet significantly increased the relative proportion of HDL-Chol. In conclusion. cholesterol- lowering effect of dietary PUFAS seemed to be a function of total fat unsaturation but hypotriglyceridemic effect seemed to be more linked to the ratty acid structure rather than the degree of unsaturation. The hypolipidemic effect of n3 PUFAs was significant so that fish oil or perilla oil may have important nutritional applications in the prevention and treatment of atherosclerotic disease.

  • A series of the herbicidal pyridylsulfonyl areas, none substitutent, 1-(4,6-dimethoxypyrimidine-2-yl)-3-(2-pyridylsulfonyl) urea, 3 and 3-trifluoromethyl substitutent, 1-(4,6-dimethoxypyrimidine-2-yl)-3-(3-trifluoromethyl-2-pyridylsulfonyl) urea, 5(Flazasulfuron) were synthesizied and the rate of hydrolysis of their has been studied in 25%(v/v) aqueous dioxane at $45^{\circ}C$. From the results of solvent effect($m{\ll}1,\;n{\ll}3\;&\;{\mid}m{\mid}{\ll}{\mid}{\ell}{\mid}$), thermodynamic parameter (${\Delta}S^{\neq}=0.54{\sim}\;-2.19\;e.u.\;&\;{\Delta}H^{\neq}=0.025\;Kcal.mol.^{-1}$), hydrolysis product analysis, $pK_a$ constant(3: 4.9 & 5: lit.4.6) and the rate equation, a marked difference in the kinetics of the reaction of 3 and 5(Flazasulfuron) was observed. It may be concluded that the hydrolysis of 5 proceeds through the $A-S_N2Ar$ reaction via conjugate acid$(5H^+)$ below pH 7.0, whereas, above pH 9.0, the hydrolysis proceeds through irreversibly $(E_1)_{anion}$ and reversibly $(E_1CB)_R$ mechanism via conjugate base(CB), respectively. But in case of 5, $A-S_N2Ar,\;(E_1)anion\;and\;(E_1CB)_R$ mechanism involved Smile rearrangement. The mate of rearrangement of 5 to a 3-trifluoromethyl-2-pyridylpyrimidinyl urea(PPU) in acid and 3-trifluoromethyl-2-pyridyl-4.6-dimethoxypyridinyl amine (PPA) in base was increased about 3.5 times by the introduction of trifluoromethyl group in the 3-position on the 2-pyridyl ring. From the basis of these findings, a possible mechanism for the hydrolysis of 5 was proposed and discussed.
