본 연구의 목적은 복부 자기공명영상에서 주로 적용되고 있는 4 종류의 펄스시퀀스를 중심으로 1.5 T 와 3.0 T 기기의 자기장의 차이로 나타나는 자기장의 속성 및 인공물 발생 차이를 비교하기 위해 분석을 하였다. PACS network로 전송된 총 500 명의 데이터를 정량적으로 SNR 값을 분석하였고, MSA, CSA, DA을 3 단계로 구분하여 정성적 평가를 하였다. 정량적 평가에서 SNR 값은 1.5 T 값 보다 의미 있는 결과로 높은 값을 얻었지만(p<0.05), 영상의 인공물이 발생하여 영상의 질을 저하시키는 요인도 있었다(p<0.05). 1.5 T는 3.0 T 보다 인공물 발생이 적어 3.0 T 만큼에 영상의 질을 보상 할 수가 있었다(0.05). 결론적으로, 이러한 결과를 토대로 자기장의 차이에 따라 발생되는 자기장의 속성 및 인공물 발생 차이를 파악 할 수 있었으며 이에 따른 대처방안을 제공할 수 있었다. 향후 임상현장에서 두 기기를 이용하여 복부 자기공명영상을 검사 할 때 환자를 직접 검사하는 MRI 사용자에게 가이드라인이 될 것이다.

The hatching of fertilized egg and early development of larval black seabream, Acanthopngrus schlegeli by immersion of 3,5,3'-triiodo-L-thyronine ($T_3$) with doses of 0.01~0.5 ppm in tank were examined for early development periods and compared with control fish immersed by 0.1 N NaOH and 99% alcohol. Larvae were fed with rotifers for first 5 days during experimental period. Yolk absorption of larvae from $T_3$ immersion groups were significantly faster than that of control. Although hatching times among each groups were not significant difference. the hatching rates of larvae in higher doses (0.1 ppm and 0.5 ppm $T_3$ groups) were significantly lower than control. The results of $T_3$ immersion experiments to newly hatching larvae indicated that exogenous $T_3$induced significant faster the absorption of yolk and oil globule, faster the development of myotome and digestive duct and higher the growth rate of larvae than larvae of control. These results indicate that $T_3$ immersion supplements appear to confer a distinct advantage to eggs and larvae of black seabream, which is in early fragile developmental stage.

Infestations of Aphis gossypii per leaf in greenhouse cultivation of cucumbers were investigated to develop binomial sampling plans. An empirical $P_T-m$ model, $ln(m)={\alpha}+{\beta}ln[-ln(1-P_T)]$, was used to evaluate relationship between the proportion of infested leaves with ${\leq}$ T aphids per leaf ($P_T$) and mean aphid density (m). Tally thresholds (T) were set to 1, 3, 5, 7, and 9 aphids per leaf to find appropriate T in greenhouse cultivation of cucumbers. Increasing sample size had little effect on the precision of the binomial sampling plan. However, the precision increased with tally threshold. The binomial model with T = 5 provided appropriate predictions of the mean densities of A. gossypii in the greenhouse cultivation of cucumbers. Using a binomial model with T = 5 (sample size = 200), a wide range of densities (1.2 - 222.8 aphids per leaf) could be estimated with precision levels of 0.346 - 0.380 for $P_T$ values between 0.15 and 0.96. Binomial models were validated at T = 5 and 7 using 12 independent data sets. Both binomial models were robust and adequately described aphid densities; most of the independent sampling data fell within 95% confidence intervals around the prediction model.

This study was carried out to examine the effects of Lactobacillus spp. on performance and cecal microflora in broiler chicks. Eight diets consisting of basal diet(C), C+Lactobacillus crispatus BC7 (T2), C+Lactobacillus reuteri BC9 (T3), C+L.reuteri BC5+L.crispatus BC9 (T4), C+L. reuteri BC5 (T1)+L.reuteri BC9 (T5), C+L.crispatus BC7+L.reuteri BC9 (T6) and C+L.reuteri BC5+L.crispatus BC7+L.reuteri BC9 (T7), were fed to Ross male broiler chicks for 5 weeks. The level of supplemented Lactobacillus spp. was 107 cfu/g diet. Body weight and feed intake were measured every week, and cecal microfla was counted at 1 and 5 weeks for Lactobacillus and yeast. Body weight increased signigicantly in supplemental Lactobacillus treatments from 2 weeks of age (p<0.05). Chicks in T2, T5 and T5 of treatments were heavier than those of other treatments at 5 weeks of age(p<0.05). Viability was not different significantly. Feed intake and feed conversion also were not different, although feed conversion improved slightly in supplemental Lactobacillus treatments. Lactobacillus spp. of cecal content was increased in supplemental Lactobacillus treatments at 1 week, but no significance was found. The number of yeast in cecum was not different from that of supplemental Lactobacillus. In conclusion, Lactobacillus, L.crispatus BC7 and L.reuteri BC9 from broiler cecum could contribute to the increase in body weight with supplemented mono-or mixing of di-lactobacilli. The results indicate that Lactobacillus feeding can benefit to intestinal lactobacillus at early growing broiler.

본 논문에서는 5G 무선국 검사에 있어, 측정 시간 단축을 위한 8T8R 콤바이너를 활용한 무선국 검사 방법에 관하여 연구하였다. 5G 무선국 검사는 배열된 안테나 수에 대응하는 RF(: Radio Frequency) 출력 신호를 개별적으로 측정해야 한다. 하지만, 본 연구에서는 개별 채널 측정 결과와 8T8R을 이용한 측정값 비교를 통해 기존 방식을 시간적으로 단축할 수 있는 5G 무선국 검사 방법을 제시하였다. 연구 결과 8T8R 콤바이너를 이용하는 경우, 정확한 무선국 검사를 수행할 수 있을 뿐만 아니라, 기존방식의 소요 시간을 1/8으로 줄일 수 있었다.

The experiments were conducted to investigate the effects of supplementary feather meal(FM) and its digest on the taurine content and performance of laying hens. Feeding trial was conducted with 810 78-wk-old ISA-Brown layers for 5wk. The experiment consisted of nine dietary treatments ； T1 ; control(basal diet), T2；Tl + feather meal(FM) 6 ％ diet, T3；T2 + pyridoxin(21 mg/kg) supplemented diet, T4； T1 + H$_2$O$_2$treated FM 6%, T5； T4 + pyridoxin(21 mg/kg) supplemented diet, T6； T1 + cystine(0.25 ％) supplemented diet, T7； T6 + pyridoxin(21 mg/kg) supplemented diet, T8； T1 + synthetic taurine supplemented(0.25％) diet, T9； T1 + synthetic taurine supplemented(0.5 ％) diet. Diets were formulated to be iso-caloric and to meet NRC(1994) requirements of essential nutriente. Birds in treatments T3 showed significantly higher(P＜0.01) egg production, feed intake, feed conversion ratio, egg weight, haugh unit and eggshell strength than those fed other treatments. Supplementation of FM. H$_2$O$_2$treated FM and cystine with or without pyridoxin did not significantly affected taurine content of egg yolk. Only synthetic taurine supplemented diets(T8 and T9) linearly increased(P＜0.01) taurine content of egg yolk.

본 연구는 조사료 생산 분야에서 화학비료를 사용하는 관행농법에서 벗어나 유기재배 기술개발을 위하여 관행재배와 유기재배의 수량성, 사료가치 등을 비교 조사하였다. 시험은 전남 강진군 작천면 소재 축산연구소의 논에서 수행하였다. 유기질 비료로는 질소성분이 4.0% 함유된 유박비료를 이용하였으며, 시험구 편성은 대조구(Con)와 대조구 질소 함량 기준으로 환산하여 유박비료 100% 처리구(T1), 유박비료 150% 처리구(T2), 유박비료200% 처리구(T3)로 구성 하였다. 시험품종은 수수${\times}$수단그라스 교잡종(SX17)을 5월 25일에 ha당 40kg을 휴립세조파(조간 50cm)로 파종하였다. 수확기 처리구별 초장은 대조구 317cm, T1 252cm, T2 269cm, T3 293cm으로 대조구가 가장 우수하였고, 시비 처리구에 따른 시험구에서는 시비량의 증가에 따라 증가하였고, 건초량은 대조구 11.386kg/ha, T1 6,015kg/ha, T2 6,799kg/ha, T3 7,627kg/ha으로 초장의 생육과 동일한 경향을 보였다. 조단백질은 대조구 7.0%, T1 5.7%, T2 6.3%, T3 5.1%로 시험 처리구에서는 T2에서 가장 높았다. 이와 같은 결과로 유박비료를 대조구 시비량 질소 함량 대비 150% 시비에서 사료가치는 유의적 차이를 보이지 않았으나, 초장과 건초량이 증가가 이루어졌으므로 150% 기준으로 시비하는 것이 적합할 것으로 판단된다.
