This experiment was conducted to study the effects of level of dietary energy and protein on the growth rate, feed intake and feed conversion of chicken. One hundred and eight male baby chicken of Leghorn was used for 56 days. Starter ration (CP-17, 20,23%; M.E-1,030, 1,200, 1,370㎉/Lb) was fed to chicken for 4 weeks from 3 to 6-week age, and finisher ration (CP-14, 17, 20%; M.E-1,000, 1,215, 1,430㎉/Lb) was fed to chicken for 4 weeks from 7 to 10-weeks age. The results obtained from this study may be summarized as follows; 1) As the level of energy or protein increased in the ration, average daily gain were increased significantly. 2) Amount of feed consumed was significantly higher as the level of dietary protein. In feed conversion, chickens fed higher protein or higher energy were much superior to the chickens fed 10 wer protein or lower energy. 3) There was no influence of dietary energy or protein level on the chicken mortality. 4) Feed cost per kilogram of full body weight gain was increased greatly as the dietary energy level increased. 5) From the above mentioned results of this experiment it was thought that C_1 was profitable level in this study.

郭鍾瀅,鄭鉉丞 진주산업대학교 1968 論文集 Vol.1 No.-

育成豚 飼料로서의 Russian Comfrey의 利用價値를 究明하고자 各各 4頭의 育成豚에 Russian Comfrey를 10%·20%· 30%씩 代置한 飼料와 基本飼料를 給與하여 比較飼養한 結果 다음과 같은 成績을 얻었다. 1)豚의 增體量은 10%代置區가 가장 優秀하였고, 30%代置區가 가장 不良하였으며, 20%代置區는 對照區와 有意差가 없었다. 2)飼料利用性도 對照區에 比하여, 10% 代置區는 優秀하였으며, 20%代置區는 비슷하고, 30%代置區는 不良하였다. 3)Russian Comfrey를 10%∼20% 程度로 代置飼養하면 飼料費가 節約되었으며, 30%代置는 不利하였다. 4)Russian Comfrey에 對한 豚의 嗜好性은 比較的 良好하였으며, Russian Comfrey 30%까지 代置給與하여도 健康上 異常은 별로 없었다. 以上의 結果로 보아 Russian Comfrey를 養豚飼料로 10%∼20% 程度 代置함으로써 有利한 經營을 꾀할 수 있다고 생각된다. The experiment was conducted to determine the feeding value of Russian Comfrey (Symphytum peregreoium) for pigs. Sixteen berkshire gilts were alloted into 4 treatments according to the levels of Russian Comfrey (R.C.) such as 0%, 10%, 20%, and 30% (on air-dried basis) in pig ration. Body weight gain, feed efficiency, economical feeding value and palatability in each treatment were investigated. The experimental results obtained were as follows: 1)In weight gain, the pigs fed 10% R.C. ration showed more gain (P<0.05), but those fed 30% R.C. ration showed less gain (p<0.05) than control group of pigs did. And the pigs fed 20% R.C. ration showed no more gain than the control pigs statistically. 2)Feed efficiency in 10% R.C. ration was also higher than that in any other rations. 3)Feed cost for 1kg. weight gain was lowest in 10% R.C. ration and slightly higher in 30% R.C. ration than that in control ration. 4)From the feed intake it was considered that Russian Comfrey should be considerably palatable to pigs. And from the above results, it was estimated that Russian Comfrey could be supplemented by 20% in the pig ration successfully.

W^(sh)/W^(sh) 마우스 고환에서 Protein Kinase C(PKC)와 c-kit의 발현 양상

곽현정,최병민,서기석,임정식,정헌택 大韓免疫學會 1996 大韓免疫學會誌 Vol.18 No.3

Protein kinase C (PKC) is a multigene family of at least nine serine/threonine kinases that are central to many signal transduction pathways. And the expression of PKC gene is strictly con-trolled by developmental stage. Mutation of the W (c kit) gene, which encodes a transmembrane tyrosine kinase receptor, affect the development and differentiation stem cells. Most homozygous W mutant mice are sterile, due to a lack of germ cells arising during embryonic development, but one of notable exception is W */Wh mice, which are fully fertile in both sexes. In order to elucidate the biological functions of PKC S and c-kit in the testes, we have examined the expression of PKC b mRNA and c-kit mRNA in While mouse testes by means of Northern blotting. North-em blot results was demonstrated that only PKC 8, 4, 8 mRNA can be detected in normal mouse testes. PKC, 8 mRNA was weakly expressed in 7 and 8-week-old mice and highly ex-pressed by 12 weeks. The PKC 8 mRNA and the c-kit mRNA was detectable in the testes of Whl Wh mouse. These results indicated that the function of the PKC a gene is necessary for the development and the W (c-kit) gene is important for the transmission of signal in testes.

부분공진기법에 의한 승압형 DC-AC 인버터에 관한 연구

곽동걸,이현우 慶南大學校 附設 工業技術硏究所 1998 硏究論文集 Vol.16 No.-

제안되는 승압형 DC-AC 인버터는 승압과 소프트 스위칭이 동시에 이루어지는 회로구조를 가진다. 인버터부에 구동되는 스위치들은 부분공진 회로부의 스위치들과 서로 동기화 되어 소프트 스위칭으로 동작하여 스위칭 손실이 저감되고, 스위칭 제어기법도 간단하다. 그리고 제안된 회로는 기존의 인버터에서 발생하는 각 상의 스위칭 아암 단락에 의한 소자 소손을 제거하는 장점도 얻게 된다. A large number of soft swithing topologies included a resonant circuit have been proposed. But these circuits increase number of switch in circuit and complicate sequence of switching operation. In this paper, the authors propose power conversion system, DC-AC inverter of high effciency and high power factor with soft switching mode by partial resonant method. The switching devices in a proposed circuits are operated with soft switching by the partial resonant method, that is PRS²MPC (Partial Resonant Soft Switching Mode Power Converter). The result is that the switching loss is very low and the efficiency of system is high. And the snubber condenser used in partial resonant circuit makes charging energy regenerated at input power source for resonant operation.

The incidence of double primary cancer is about 10% in all kinds of cancers. Double primary cancer is usually accompanied by gastrointestinal cancer. Esophageal cancer is supposed to be frequently accompanied by squamous cell carcinoma of the head and neck or the upper respiratory tract, because of such common carcinogens as smoking and alcohol ingestion. Esophageal cancer and hypopharyngeal cancer are usually diagnosed by esophagogastric endoscopy with biopsy. We performed endoscopic ultrasound-guided Trucut biopsy(EUS-TCB) to diagnose a mediastinal mass in a 49 year-old patient, who visited our hospital because of voice change. During procedure, we accidently found enlarged celiac lymph node, and obtained tissue from the mediastinal lymph node and the celiac lymph node. We confirmed double primary cancer of squamous cell carcinoma in the esophagus and the hypopharynx via esophagogastric endoscopy.
