<P>BACKGROUNDAntibiotics used as growth promoters in livestock have been banned in the European Union since 2006. Alternatives of antibiotics have focused on phytogenic plants, such as herbs and medicinal plants. No studies have evaluated the use of fermented medicinal plants (FMP) made up of Gynura procumbens, Rehmannia glutinosa and Scutellaria baicalensis in weanling pigs. Therefore, an experiment was conducted to determine the effects of FMP on growth performance, nutrient digestibility, fecal noxious gas emissions and diarrhea score in weanling pigs. RESULTSFMP supplementation increased (P < 0.05) average daily gain, average daily feed intake, gain:feed, apparent total tract digestibility of dry matter, nitrogen and gross energy compared with NC treatment, while a linear effect (P < 0.05) was observed on those criteria. Ammonia, total mercaptans and hydrogen sulfide concentrations were decreased (P < 0.05) by the supplementation of FMP compared with NC. Additionally, diarrhea score was lower (P < 0.05) by FMP addition compared with NC during days 0-7 and days 8-14. CONCLUSIONThese results suggested that FMP could be used as an alternative to antibiotics by enhancing growth performance and nutrient digestibility, and decreasing fecal noxious gas emission and early diarrhea score of weanling pigs.

<P><B>Background</B></P><P>Dietary nucleotides, considered as antibiotics alternative, were shown to have positive effects on intestinal hyperaemia, systemic immunity, small-intestinal growth, and hepatic composition in pigs. However, there is no previous research on nucleotide supplementation in weanling pigs under an oral challenged <I>E. coli</I> K88. Therefore, 2 experiments were conducted to investigate the effects of dietary nucleotides on weanling pig growth performance, nutrient digestibility, fecal score, and blood profile after being orally challenged with <I>E. coli</I> K88.</P><P><B>Methods</B></P><P>In Exp. 1, a total of 140 weanling pigs [8.33 ± 0.33 kg of body weight (BW), 28-d old] were used in this 42-d feeding trial. Pigs were distributed into 1 of 4 treatments, 5 pigs/pen (3 barrows and 2 gilts) and 7 pens/treatment. Treatments were a control basal diet (CON) or the CON supplemented with 150 (R150), 220 (R220), or 275 (R275) mg/kg to give the three treatment diets. In Exp. 2, 28 weanling pigs (BW = 8.40 ± 0.22 kg, 28-d old) were distributed into 1 of 4 treatments to give 1 pig/pen and 7 pens/treatment in a 42-d feeding and challenge trial. Dietary treatments were the same as in Exp. 1. On d 14, all those pigs (BW = 13.3 ± 0.15 kg, 42-d old) were orally dosed with 1.5 mL suspension containing 10<SUP>10</SUP> cfu/mL of <I>E. coli</I> K88. Twenty four hours after challenge, blood and excreta samples were collected from each pigs for analysis. Fecal scores were measured on d 7, 14, 21, and 28 of the study.</P><P><B>Results</B></P><P>In Exp. 1, overall BW, average daily gain (ADG), gain/feed (G/F) ratio, and nutrient digestibilities were lower (<I>P</I> < 0.05) in CON group compared with the nucleotides fed pigs. In Exp. 2, after challenge, IgA, IgM, and IGF-I were higher (<I>P</I> < 0.05) in the nucleotide groups compared with CON. However, the nucleotide groups had lower (<I>P</I> < 0.05) cortisol and TNF-α compared with CON. Fecal <I>E. coli</I> counts and fecal score for the nucleotide groups were lower (<I>P</I> < 0.05) than for CON.</P><P><B>Conclusions</B></P><P>In conclusion, dietary nucleotides supplementation could improve growth performance, nutrient digestibility, immune status, microbial balance, reduce diarrhea, and provide protection against enterotoxigenic <I>E. coli</I> K88 infection in weanling pigs.</P>

In the electrolytic capacitor-less PMSM drives, the LC resonance between small film capacitor in the DC bus and the inductance in the grid side is analyzed in this paper. Since the electrolytic capacitor is replaced by a small film capacitor in the DC bus, the LC resonance phenomena cannot be neglected, which will result in the underdamping characteristics of the electrolytic capacitor-less motor drives. Hence, the detailed model is established to reveal the resonance mechanism. Based on the model, a current harmonics suppression strategy is also proposed. The proposed control strategy can improve the power factor and reduce the current harmonics in the grid side. In addition, it can improve the system efficiency and enhance the stability of the drives. The proposed method is experimentally validated on an electrolytic capacitor-less PMSM drive applied in 1.5 HP variable frequency air-conditioner.

본 논문에서는 고성능/고용량 투명 인공지능 메모리 칩 개발을 위해 TiO₂/TiO2-x 박막 구조를 기반으로 한 저항 변화형 메모리를 제작하였으며, TiO2-x 활성층 박막에 저진공 산소 플라즈마 처리를 하여 인가하는 RF power에 따른 저항 변화형 메모리 디바이스의 전기적, 표면적 성능 분석하였다. 인가하는 RF power의 세기가 클수록 hysteresis area가 크게 나타났으며, TiO2-x 박막 표면의 RMS 값이 감소하는 결과를 보였다.
