On farm evaluation for the control of airborne diseases like FMD and flu virus has been done in past but control of disease in process of transportation of livestock and manures is still needed. The objective of this study was to predict a common pattern of livestock vehicles movement. The analysis were done on GPS data, collected from drivers of livestock vehicles in Jeju Island, South Korea in year 2012 and 2013. The GPS data include the coordinates of moving vehicles according to time and dates, livestock farms and manure keeping sites. 2012 year data was added to ArcGIS and different tools were used for predicting common vehicle moving pattern. The common pattern of year 2012 were determined and considered as predicted common pattern for year 2013. To compare with actual pattern of year 2013 the same analysis was done to find the difference in 2012 and 2013 pattern. When the manure keeping sites and livestock farms were same in both years, as a result common pattern of 2012 and 2013 were similar but difference were found in patterns when the manure keeping sites and livestock farms were changed. In future for more accurate results and to predict the accurate pattern of vehicles movement, more dependent and independent variables will be required to make a suitable model for prediction.

영지(靈芝)버섯(Ganoderma lucidum (Fr.) Karst.)의 16개 균주간(菌株關) 특성을 전기영동법(電氣泳動法)을 사용(使用)하여 단백질(蛋白質) pattern과 esterase, LAP의 동립효소(同位酵素) pattern에 의해 비교(比較) 관찰하여 다음과 같은 결과를 얻었다. 1. 자실체(子實體)의 esterase의 band pattern은 각(各) 균주간(菌株間) 특정 band의 유 무(有 無)와 위치(位置) 등에 의해 분류(分類) 할 수 있었으며 자실체(子實體)의 형태(形態)가 유사한 것은 band pattern에서도 유사하였다. 2. 동일균주(同一菌株)에서 편각(扁角)과 녹각형태(鹿角形態)로 형성(形成)된 자실체(子實體)의 esterase band pattern은 서로 동일(同一)한 pattern을 보였다. 3. 균주간(菌株間) 유연관계인 유사도 지수는 12.5%에서 100%의 변이 폭을 보였다. 특히 6과 7번의 두 균주간(菌株間)과 13,14,15,16번의 4균주간(菌株間)은 유사도지수가 100%이므로 유전적(遺傳的)으로 동일(同一)한 균(菌)이라 사료(思料)된다. 4. 균사(菌絲)의 단백질(蛋白質)과 esterase의 band pattern은 자실체(子實體)의 pattern과는 달랐으며 자실체(子實體)에서 동일(同一)한 pattern을 보였던 균주간(菌株間)에서도 균주간(菌株間) 특성을 가장 잘 보여 주었으므로 영지(靈芝)버섯 분류(分類)에는 균사(菌絲)의 esterase pattern이 가장 적합하다.

본 실험은 수도의 유전연구에 전기영동법을 도입함에 있어 기초조사를 하기 위하여 수도 조직내의 몇가지 산소가 부위별로 차이가 있는지 또한 생장 조절제인 GA를 처이함으로 같은 산소의 동위효소 pattern이 변하는지 '아끼바레'와 '유신' 두 품종을 사용 조사하였다. 그 결과는 다음과 같았다. 1. Isoelectrofocusing에 의한 종자, Shoot, Root의 Esterase, Phosphatase, Amylase 동위효소 pattern은 두 품종 모두 조직부위별로 다른 pattern을 보였다. 2. 7％ polyacrglamide slab gel electrophoresis에 의한 Peroxidase 동위효소 pattern도 두 품종 모두 조직부위별로 다른 Pattern을 보였다. 3. GA(10/sup -5/)을 처리했을 경우 Esterase 동위효소 pattern은 '아끼바레'의 root와 '유신'의 shoot, root에서 대조구와 차이가 있었으며 Phosphatase의 동위효소 pattern은 '아끼바레'의 root에서 차이가 있었다. Amylase와 Peroxidase의 동위효소 pattern은 대조구와 GA 처리간에 차이가 없었다.

This study was carried out to investigate the antibiotic resistance pattern of Enterococcus spp. and Staphylococcus aureus (S. aureus) isolated from chicken feces. All isolates showed high resistance to erythromycin (E) and tetracycline (TE). Of the 63 Enterococcus faecalis (E. faecalis) isolates, 73.0% were resistant to E and 98.4% to TE. Of the 44 Enterococcus faecium (E. faecium) isolates, 50.0% were resistant to E and 95.5% to TE. Of the 52 S. aureus isolates, 57.6% were resistant to E and 96.2% to TE. The prevalence of two and three drugs resistance pattern were 28.6% and 17.5% of E. faecalis, 40.9% and 25.0% of E. faecium and 38.5% and 23.1% of S. aureus, respectively. The multiple resistance pattern to six drugs was observed in 1 E. faecalis isolates, and five drugs resistance pattern were seen in 1 E. faecalis, 1 E. faecium and 1 S. aureus isolates. The prevalence of resistant organisms in Korea probably reflects lack of proper antibiotic policy resulting in prolonged and indiscriminate use of antimicrobial agents.

The present study was conducted to examine the effect of a stair-stepped feed intake pattern on growth, feed efficiency, and meat quality of Hanwoo steers. Twenty-seven 11-month-old Hanwoo steers were randomly divided into three groups. The control group was fed according to the Korean steer feeding program, and the other two groups were fed according to an alternated feeding schedule of 3-2-4-2 months. During the first three months of the experiment, treatment group 1 (T1) and treatment group 2 (T2) were fed 20% and 30% less than the control group, respectively. For the following two months, the T1 group was fed 20% more than the control group while the T2 group was fed 20% less than the control group. In the third step, T1 and T2 groups were fed 20% and 10% less, respectively, than the control group for four months. In the last two months, T1 and T2 groups were fed 20% more than the control group. After the stair-step feeding trial, steers were fed concentrated feed ad libitum for five months. The altered feed intake pattern did not affect daily body weight gain. However, daily feed intake tended to decrease and growth efficiency tended to increase in the two treatment groups compared to the control group. Altered feed intake also affected blood metabolite levels. The serum glucose and BUN level of the T1 group increased in the first re-fed period compared to the T2 and control groups. The serum cholesterol level of the T2 group decreased in the first restricted-re-fed growth period compared to the T1 and control groups. The serum NEFA levels of the two treatment groups increased from the first restricted period compared to the controls. The serum insulin level of the T2 group increased in the last period compared to the T1 and control groups. Regarding meat yield index, the control group was significantly higher than the T2 group (p<0.05). Regarding meat yield grade, the carcass back fat thickness of the T2 group was significantly higher than the control group (p<0.05). In marbling score, the T1 group was the highest (4.9), followed by the control group (4.1) and the T2 group (4.0). These results indicate that using a stair-stepped growth pattern (T1) can contribute to improvements in growth efficiency and muscle marbling.

도열병균(Pyricularia oryzae) 균사체의 esterase 동위효소 pattern이 배양조건에 의하여 변화되는가를 $10\~25\%$ polyacrylamide gradient slab gel을 사용하여 알아보았다. 배양기간에 따라 배양 24일까지 동위효소 pattern은 변하지 않았지만 특징 band의 효소량에는 차이가 있었다. 탄소원(glucose, fructose, maltose, sucrose, starch), 단포자분리균주간, 계대배양 및 세포벽재생균주간의 동위효소 pattern은 변함이 없었다.
