목초의 종류에 따라서는 發芽에 적합하지 않은 온도에서 파종되는 경우가 흔히 있다. 때문에 목초의 發芽率에 미치는 온도의 영향은 물른 발아가 가능한 온도의 범위를 목초 품종에 따라 알아두는 것이 중요하다. 'MO - 20' Birdsfoot trefoil (Lotus corniculatus L.) 과 섬바디(Dystaenia takesimana kitagawa) 의 種子를 3, 6, 9, 12, 15, 20, 25, 그리고 30℃로 고정시킨 發芽箱子들에 넣어서 각 온도와 시간이 발아에 미치는 영향을 연구하였다. 섬바디 종자들은 12 ~25℃ 범위에서만 발아되었고 培養溫度는 발아가 시작되는 시간과 거의 상관이 없었다. 섬바디와는 달러 Birdefoot frefoil의 경우 발아온도와 종자들이 50% 발아되는 시간의 逆數와는 線型적 상관관계가 있었다. 이는 종자의 발아가 온도 이외의 다른 요인이 작용함을 뜻한다 하겠다. Birdsfoot foil의 발아 기본온도는 4.7℃인 것으로 계산되었으며, 9~12℃에서의 發芽率이 급격히 증가하는 것으로 보아 여기에는 Arrhenius 反應, 즉 온도에 따라 급격한 영향을 받는 현상이 있는것 같다. Forage species are often planted in soils that are not at the optimum temperature for germination. Therefore, it is important to know the temperature range of germination, as well as the temperature effect on germination rate. Then appropriate management practices can be developed for that species. Temperature effects on the time course of seed germination of 'MO-20' birdsfoot trefoil (Lotus corniculatus L.) and seombadi (Dystaenia takesimana Kitagawa) were studied using germination chambers at constant temperatures of 3, 6, 9, 12, 15, 20, 25, and 30℃. Total germination percentages of both species were highest at 20℃. Time to start of germination of birdsfoot trefoil was much faster as temperatures increased. Seombadi seeds germinated only between 12 and 25℃ with little temperature influence on time to start of germination. There was a linear relationship for birdsfoot trefoil between germination temperature and the reciprocal of time to reach 50% of final germination, but there was no relationship for seombadi suggesting factors other than temperature were controlling the response. Base temperature for germination of birdsfoot trefoil was calculated to be 4.7℃. Germination rate of birdsfoot trefoil showed a marked increase between 9 and 12℃ suggesting an Arrhenius response, i.e. , and abrupt change in effect of temperature.

子葉과 葉의 展開가 幼植物 生長과 어떠한 관계가 있는가를 조사하기 위하여 6가지 荳科 牧草의 子葉과 葉의 展開過程을 비교 검토하였다. 荳科 牧草의 子葉은 出現후 1주일 동안은 급격히 신장되었으며 그 이후는 서서히 확장되다가 탈락되었다. 종자는 크기가 클수록 子葉 면적도 컸으며 子葉伸張과 幼植物 生育과는 밀접한 관계가 있었다. 그리고 빠른 本葉 出現과 初期 신속한 葉展開는 초기 幼植物 生長에 있어서 결정적인 요인이 되었다.

Oncologic Outcomes of Colon Cancer Patients with Extraregional Lymph Node Metastasis: Comparison of Isolated Paraaortic Lymph Node Metastasis with Resectable Liver Metastasis

Bae, S. U.,Han, Y. D.,Cho, M. S.,Hur, H.,Min, B. S.,Baik, S. H.,Lee, K. Y.,Kim, N. K. Springer Science + Business Media 2016 Annals of surgical oncology Vol.23 No.5

<P>The treatment strategy and benefit of extended lymph node dissection among patients with preoperatively diagnosed paraaortic lymph node metastasis (PALNM) in colon cancer remains highly controversial. In the current study, we analyzed the oncologic outcomes of patients who underwent extraregional lymph node dissection for colon cancer with isolated PALNM. From March 2000 to December 2009, the study group included 1082 patients who underwent curative surgery for colonic adenocarcinoma with pathological lymph node metastasis. Of 1082 patients who underwent curative surgery for colonic carcinoma, 953 (88.1 %) patients underwent regional lymphadenectomy, and 129 (11.9 %) patients underwent paraaortic lymph node dissection. Pathologic examination revealed N1 stage disease in 738 (68.2 %), N2 in 295 (27.3 %), and PALNM in 49 (4.5 %). Five-year overall survival (OS) and disease-free survival (DFS) rate were significantly better in the regional LNM group than in the PALNM group (OS 75.1 vs. 33.9 %, p < 0.001; DFS 66.2 vs. 26.5 %, p < 0.001). Five-year OS and DFS were not significantly different between the PALNM and resectable liver metastasis patients who underwent curative resection (OS 33.9 vs. 38.7 %, p = 0.080; DFS 26.5 vs. 27.6 %, p = 0.604). PALNM in colon cancer is associated with poorer survival than regional lymph node metastasis and showed comparable survival rates with metastasectomy for liver metastasis. Further studies evaluating the net benefit of upfront chemotherapy compared with initial resection for patients with potentially resectable PALNM are needed.</P>

A 105-day feeding trial with 3-way crossbred piglets were conducted to inversigate the feedin values of dehulled soybean meal and dry extruded full-fat soybean in pigs. A total of 45-day-old 72piglets were randomly allotted to four dietary treatments ; the Control treatment, two dehulled soybean meal treatments in which dehulled soybean treatment in which full-fat soybean replaced tallow and pert of soybean meal in Control. There were 3 replicates per treatment and 6 piglets (3 female and 3 castrated male) per replicate(pen). Four all-mash experimental diets were formulated to have similar levels of energy and protein. Economic evaluations were conducted upon the completion of the feeding trial. When dehulled soybean meal replaced soybean meal a part or all of fish meal in Control, the growth performance of pigs appeared to improve but not enough to show a significant degree. However, the feed cost per ㎏ gain was lowered greatly by replacing soybean and fish meal with dehulled soybean meal. When full-fat soybean replaced soybean mel and tallow in Control, pigs appeared to grow faster and consume more feed during starting and growing period, without any change in feed efficiency. During the finishing period, however, no difference in growth performance was found by the replacement. Throughout the overall feeding period, the feed cost per ㎏ gain in pigs fed full-fat soybean was similar to that of Control. Notably, the feed cost per ㎏ gain during starting and growing period increased by the use of full-fat soybean. During the finishing period, however, the trend was reversed. In conclusion, the growth performance of pigs was affected favorbly by the use of defulled soybean meal replacing regulat soybean meal and fish meal. Moreover, the use of dehulled soybean meal turned out to be economically advantageous. The growth performance of pigs was not affected adversely by the use of full-fat soybean in replacement for soybean meal and tallow. Economically, more favorable results may be expected if the usage of full-fat soybean be limited to the finishing period.

In an effect to study experimental animal farms of universities for student practice and faculty teaching purpose, current situation and future development plans of 8 national and, 5 private universities, and 6 agricultural junior colleges were investigated. Results were as follows :1. In general, many of the university farms were too small in size or not funded enough to carry out its own function as for teaching and student practice as well as research. Man power for the farm management was also in very short supply. 2. Number of animal breeds and heads, and their productivity were far below than what they supposed to be, mainly due to the short support of the farm by the gocernment of the university. 3. Farm buildings, facilities and farm land for forage production were also very old and poor. 4. One of the major limitations against university experimental farm operation was the government or the university regultion that requested a certain level of income to be returned out of the farm operation. 5. Having above mentioned problems and not properly supported by the government or universities, all the personal who were in needs of using experimental farm at the univerrsity had a strong desire to have a minimum size of experimental farm at least for teaching, student practice and ressarch. 6. To maintain an experimental farm to be functioned as desired the urgent needs of Chonbuk National University's animal farm were estimated to have farm buildings, facilities and animals with proper amount of operating funds to maintain, 40 ha of farm land including grassland, 35 dairy cows, 10 of each beef and korean cattles, 120 pigs, 1500 chicks, 10 sheep, 10 goats and 100 rabbits.

In order to evaluate the effect of vaccinantion for hog-cholera virus, sera were collected from each 20 piglet out of 26-32 days old before vaccination, and then from the 14th and 28th day post-vaccination(PV) with LOM live virus vaccine at the J and C swine ranches in the suburbs of Chonju. Monoclonal antibody(MAb) against ALD strain of hog cholera virus(HCV) and goal antimouse FITC-conjugates were employed in indirect immunofluorescence(IF) test for the titration of HCV and neuralization IF test for serum neutralization(SN)-Ab-titers against HCV. SN-Ab-titers(M±S.D.) were <2±0 in all piglets before vaccination at the both swine ranches. Whereas SN-Ab-titers of the J and C swine ranches were 111.2±115.08 and 144±121.7 at the 14th day PV and were 361.6±279.6 and 723.2±966.2 at the 28th day PV, respectively. Compared with Duncan's test, SN-Ab-titers were not significantl difference between the H and C swine ranches of the 14th day PV, but were significantly difference at the 28th day PV (P<0.0009). Therefore, SN-Ab-titers were significantly difference between the 14th and 28th day at the J or C ranches, respectively(P<0.0007, P<0.0114). Excepting SN-Ab-titer was1:16 in one piglet of the 14th day PV at the J swine ranch, defensible levels of SN-Ab-titers could be detected in all piglets PV of the both swine ranches. It is suggested that varied dffect of vaccination against HCV may be depended by feed and mangement, enviroment, sanitary conditions, breed and pedigree or vaccination program, etc.

A hydraulic system of an equipment or machinery is a carefully balanced interdependent network. Hydraulic components are designed to work together to get required performance. Every day, however, many factors work to erode their efficiency and performance. Today's industry trend in design and manufacturing is more and more towards sophisticated systems, tighter clearances and easier handling. In this thesis, we developed a performance test equipment for hydraulic proportional control valve. This can be used to test the performance of hysteresis, dead zone and linearity. Performance test results for hydraulic proportional control valve are reliable and stable.

N/A There had been a considerable trouble in the management of refractory acites combined with liver cirrhosis. Such refractory ascites in advanced liver cirrhosis does not respond to conventicnal therapy such as bed rest, salt restriction, massive diuretics and albumin infnsion. And there are also serious corrplications including hepatic encephalopathy, functicnal renal failure and hyponatremia with massive administration of diuretics. So peritoneovenous shunt(Leveen shunt) had been developed in order to promote effective circulatory volume with increased renal function. But relatively large and serious complications such as DIC, fever, infection, pulmonary edema and pulmonary embolism had limited its widespread use in the magement of refractory ascites. So we have experienced intraperitoneal reinfusion of ultrafiltered ascites for 20 patients with intractable ascites combined with liver cirrhosis. We had performed this procedure via ultrafilter which was usually used in hemodialysis and pump. And the following results werc acquired. 1. About 6200 cc of acites was ultrafiltered for average 4. 5 hrs. and loss of body weight was 6.7kg which was more than the amount of filtered ascites. 2, Increasing tendency in serum albumin concentration after ultrafiltration with peak concentration about 0. 5 gm/dl gain at 3rd after this procedure. There were significant increase in the amount of daily urine output but statisitically nonsignificant increase in creatinine clearance. 4, The complications of this procedure were light headache, hearing disturbance, dizziness and there was no more serious complication such as DIC, variceal rupture, pulmonary edema. There was no recurrence of reaccumulation of ascites within 3 months with one time procedure in a certain case. The repeated with average of 4-6 weeks interval had controlled such refractory ascites. In summary, above results supported that intraperitoneal reinfusion of ultrafiltered ascites have beneficial effect in the control of refractory ascites combined with far advanced liver cirrhosis. The advantages of this procedure are the followings. 1.Low cost. 2. Time saving. 3. Ambulatory control. 4 Less complication. 5. Corresponding effect to intravenous albumin infusion (4-5 bottles)
