중국어 병음은 초급 단계의 중국어 교육에서 반드시 필요한 중요 도구로 그 중요성은 이미 중국어 교육학계에서 중요하게 인식되고 있으며 나날이 높은 관심과 중시를 받고 있다. 초급 중국어 교재에서는 어떻게 병음을 표기하느냐 하는 문제에 직면하게 된다. 본문에서는 초급 중국어 교재의 병음 표기와 단어를 기준으로 하여 띄어쓰기 하는 分詞連寫에 대하여 토론하고자 한다. 8권의 초급 중국어 교재의 병음 표기 상황을 대비 분석하고 이 교재들의 병음 표기와 《汉语拼音正词法基本规则》의 보편적인 차이와 개별적 차이 및 각 교재 내부의 불일치 현상에 대해서 연구하였다. 초급 중국어 교재의 편찬에서 병음 표기의 총체적인 원칙에 대해 3가지 의견을 제시하고, 또한 구체적인 分詞連寫에 대하여 6가지 의견을 제시하였다.

In spray pyrolysis, the effects of the preparation temperature, flow rate of the carrier gas and concentration of the spray solution on characteristics such as the morphology, size, and emission intensity of Ca8Mg(SiO4)4Cl2:Eu2+ phosphor powders under long-wavelength ultraviolet light were investigated. The phosphor powders obtained post-treatment had a range of micron sizes with regular morphologies. However, the composition, crystal structure and photoluminescence intensity of the phosphor powders were affected by the preparation conditions of the precursor powders. The Ca8Mg(SiO4)4Cl2:Eu2+ phosphor powders prepared at temperatures that were lower and higher than 700˚C had low photoluminescence intensities due to deficiencies related to the of Cl component. The phosphor powders with the deficient Cl component had impurity peaks of Ca2SiO4. The optimum flow rates of the carrier gas in the preparation of the Ca8Mg(SiO4)4Cl2:Eu2+ phosphor powders with high photoluminescence intensities and regular morphologies were between 40 and 60 l/minute. Phosphor powders prepared from a spray solution above 0.5 M had regular morphologies and high photoluminescence intensities.

Two experiments were conducted to determine the effect of wood vinegar (WV) on the fecal microbes and gas emission in weaned pigs. In Exp. 1, 224 weaned piglets (L×Y×D, 21 d-old, initial BW 6.02 ± 0.52 kg) were assigned to four treatments of different WV levels in randomized completely block design with four replicates (14 piglets/pen) for 28 days, including phases I (0-2 wk) and phase II (3-4 wk). The dietary treatments were 0, 0.1, 0.2 and 0.3% of WV added to a corn-soybean meal basal diet. The concentration of ammonia measured at 0 h and 24 h in feces did not differ among dietary treatments (p>0.05), but it was linearly decreased (p<0.05) in 0.2% and 0.3% addition level measured at 48 h and 72 h. The concentration of hydrogen sulfide had no significant change (p>0.05) within treatments measured at different time. The fecal total bacteria (TBC), Lactobacilli(LAB) and E. coli were measured on 14 d and 28 d. TBC were higher (p>0.05) in WV added treatments than the control. Similar results were obtained for LAB. But E. coli populations were decreased (p<0.05) in treatments added WV compared to control measured on 14 d and 35 d. In Exp. 2, 288 weaned piglets (L×Y×D, 21 d-old, initial BW 6.62 ± 0.31 kg) were assigned to four treatments in a randomized completely block design with four replicates (18 piglets/pen) for 28 days. The dietary treatments were basal diet (negative control, NC), 0.2% organic acid (positive control, PC), 0.2% antibiotic (AT) and 0.2% WV added to a corn-soybean meal basal diet. The fecal total bacteria (TBC), Lactobacilli(LAB) and E. coli were measured on 14 d and 28 d. TBC, LAB and E. coli showed lower counts in pigs fed AT diets than others. In conclusion, these results indicated that wood vinegar could reduce the NH3 concentration of feces and inhibited the growth of harmful bacteria.

The effects of Lotus (Nelumbo nucifera Gaertner) leaf dry powder on serum lipid concentrations were evaluated in rats. Forty-eight male Sprague-Dawley rats were divided into six groups and fed high fat diets for sis weeks. Experimental groups were following diets; Control group (CON), 40 % animal and plant high fat group (AHF and PHF) control with 2% Lotus leaf dry powder group (CLDP), animal and plant high fat diets with 2% Lotus leaf powder group (AHFLDP, PHFLDP). Tissue weights of liver, heart, kidney, spleen and lung of AHF group exposed rats were decreased by PHFLDP groups. The concentrations of serum triglyceride in rats fed the CLDP and PHFLDP group were lower than those in other groups. The concentrations of total cholesterol in CLDP and PHFLDP group the were lower than those in AHF groups. The concentrations of HDL-cholesterol in serum of the CLDP and PHFLDP groups were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the CLDP and PHFLDP groups were tended to be lower than those of other groups. GPT and GOT were decreased in CLDP and PHFLDP groups and than in the AHF group. LDHase was lower in CLDP and PHFLDP groups than in the AHF group. These results suggest that 2% Lotus leaf dry powder groups may reduce elevated levels of serum lipid concentrations in rats fed high fat.

In order to investigate the effects of magnetized water treated with HI-Scalper153R on body performance and ammonia concentration in feces of broiler chicks, a feeding trial was conducted with a total of 180 broiler chicks. Each treatment had 18 chicks with 5 replications. Chicks during experimental periods, broiler chicks were fed magnetized water and subterranean water, respectively. The results obtained summarized as follows: Body weight gain slightly increased for broiler chicks fed magnetized water compared with control. But, there is no significantly (p=0.36) different among treatments. Feed intake significantly (p=0.046) decreased for broiler chicks fed magnetized water compared with control. Feed efficiency was significantly (p=0.020) improved for broiler chicks fed magnetized water of each periods when compare to the control. Especially, in starter periods, the feed efficiency of magnetized water treatment increased by 10% more than control (1.80 vs 1.69). In feces, average ammonia concentration (ppm) significantly (p=0.004) decreased in the magnetized water treatment compare to control. Especially, the magnetized water treatment decreased by 2.2 times compared to the control in ammonia concentration of feces (83 vs 37ppm).
