  • PCR-RFLP analysis was carried out to investigate the genotype of Melanocortin receptor 1 (MC1R) gene in Korean Brindle Cattle and Korean Cattle with dark muzzle, which are coat color and muzzle pigmentation variants of Korean Cattle, respectively. Allelic variants of MC1R in cattle were analyzed by digestion with BsrFⅠ, AciⅠ. Among six genotypes, $E^D/E^D,\;E^D/E^+,\;E^D/e,\;E^+/E^+,\;E^+$/e and e/e, detected in cattle, only two genotypes, $E^+/E^+\;and\;E^+$/e, were observed in Korean Brindle Cattle, probably reflecting the necessary of $E^+$ allele for the expression of black brindle coat color. As in Korean Cattle with light muzzle, the $E^+$/e and e/e genotypes were detected in Korean Cattle with dark muzzle. The $E^+$ and e alleles frequencies in two populations of Korean Cattle with dark muzzle and with light muzzle were 0.37, 0.63 and 0,11, 0.89, respectively. Although the frequency of $E^+$ allele in Korean Cattle with dark muzzle was higher than in Korean Cattle with light muzzle, the $E^+$ allele was not completely associated with dark muzzle pigmentation. The results of this experiment indicate that the difference of MC1R genotype and frequency may be useful for fixation of coat color in Korean Cattle as well as Korean Brindle Cattle.

  • De notre temps, nous faisons face ${\grave{a}}$ un changement du $th{\hat{e}}atre$ dans son ensemble. Le $th{\acute{e}}atre$ contemporain tente de se $d{\acute{e}}marquer$ des autres formes artistiques, mais aussi des formes $litt{\acute{e}}raires$, lorsque la tendance est ${\grave{a}}$ la fusion des genres. Il existe ainsi de plus en plus de $th{\hat{e}}atre$ ${e}xp{\acute{e}}rimentaux$, $n{\acute{e}}s$ sous le nom de $th{\acute{e}}atre$ anthropologique, $th{\acute{e}}atre$ sociologique, $th{\acute{e}}atre$ ethnologique, $th{\acute{e}}atre$ ${\acute{e}}pist{\acute{e}}miologique$ ou $th{\acute{e}}{\hat{a}}tre$ interculturel. La $m{\acute{e}}thodologie$ doit elle s'adapter ${\grave{a}}$ cette tendance de fusion? Au lieu de trouver une $m{\acute{e}}thode$ d'anlyse de chaque "nouveaux genre" $n{\acute{e}}$ de la fusion, nous nous interrogeons sur la $m{\acute{e}}thodologie$ pour ${\acute{e}}tudier$ le $th{\hat{e}}atre$ dans son ensemble. Si une telle $m{\acute{e}}thodologie$ d'analyse existait, quelle serait la $diff{\acute{e}}rence$ avec la $m{\acute{e}}thodologie$ $d{\acute{e}}j{\grave{a}}$ existante? Et si elle n'existait pas, quelle serait la meilleure $m{\acute{e}}thodologie$ $adapt{\acute{e}}e$? Nous $consid{\acute{e}}rons$ la $m{\acute{e}}thode$ d'analyse de la didascalie comme nouvelle $m{\acute{e}}thodologie$ $adapt{\acute{e}}e$. En effet, la didascalie $conna{\hat{i}}t$ sans cesse des $m{\acute{e}}tamorphoses$ dans $l^{\prime}{\acute{e}}criture$. De nombreux $th{\acute{e}}oriciens$ ont $d{\acute{e}}velopp{\acute{e}}$ des $m{\acute{e}}thodes$ d'analyse afin de mieux comprendre les diverses formes de $th{\acute{e}}atre$ comtemporain et ses didascalies. Notre travail est de rassembler les ${\acute{e}}tudes$ des $diff{\acute{e}}rents$ $th{\acute{e}}oriciens$ et de les ordonner ; afin de proposer un outil d'analyse $adapt{\acute{e}}$ pour $l^{\prime}interpr{\acute{e}}tation$ des $pi{\grave{e}}ces$ du $th{\acute{e}}{\hat{a}}tre$ contemporain.

  • 21명의 간흡충 감염환자 및 15명의 건강인으로부터 혈청을 수집하여 혈청내 IgE와 간흡충에 대한 특이 IgE 항체를 RIST와 RAST법을 이용하여 측정하였다. 간흡충 감염환자 및 건강인의 혈청 IgE와 특이 IgE는 각각 2,372 lU/ml과 364IU/ml 그리고 52.0%와 4.4%로 간흡충 감염자에서 모두 유의하게 상승되어 있었으며 (p<0.001 및 p<0.01), 혈청 IgE의 상승과 특이 IgE의 상승은 상호 밀접한 관계가 있었고(r=0.9451), 혈청 IgE와 EPG(r=0.6056), 특이 IgE와 EPG(r=0.5693) 역시 상관 관계가 있었다. 이상의 결과로 보아 간흡충 감염은 인체 혈청내 IgE 및 특이 IgE항체를 상승시키며, IgE 및 간흡충에 대한 특이 IgK는 숙주-기생충간의 면역반응에 관여할 것으로 생각된다.

  • 본 논문은 기존에 선행 연구된 연구 자료를 비교${\cdot}$분석하여 e-러닝 환경 변화에 따른 현재 e-러닝의 문제점을 분석해보고 유비쿼터스 환경에서의 차세대 e-러닝의 방향에 대해 연구하였다. 특히 유비쿼터스 환경에서의 e-러닝에 대한 구축모델을 제안하여 앞으로의 e-러닝 발전 방향에 대해 살펴보았다. 우리나라의 경우에서처럼 인터넷 인프라 환경이 잘 갖춰져 있어 사교육비를 절감하고, 소외계층에 대한 생산성 향상에 크게 기여할 수 있는 e-러닝은 아직 태동단계라 축적된 정보가 많지 않지만, 무궁무진한 성장잠재력을 갖고 있으며, 앞으로도 끊임없이 연구되어야 할 부분이기도 하다. 본 논문에서 e-러닝의 현 상황의 문제점을 지적해보고, 유비쿼터스 환경에서의 구축모델을 제안함으로써 e-러닝의 앞으로 나아가야할 방향과 전망을 연구해보았다. 본 논문에서는 특히 향후 도래할 유비쿼터스 컴퓨팅 환경에서의 e-러닝을 접목함으로써 새로운 교육의 패러다임으로 이동되는 e-러닝의 활용 방안을 연구하여 앞으로 e-러닝의 나아가야할 방향을 연구하고자 하였다.

  • Hc nuclear polyhedrosis virus DNA genome was digested with EcoRI endonuclease, these partial fragments were recombined into the pUC8 plasmid vector and transformed in E. coli JM 83 cell. The genome DNA has 24 EcoRI fragments and 12 fragments of them were subcloned. The four recombinants were named as eNP-O, eNP-Q, eNP-R and eNP-S. The expression of foregin gene of the recombinants was investigated by analysing protein patterns on the SDS-PAGE. The eNP-O, eNP-Q and eNP-R were expressed a different weight of protein as comparision with potypeptide bands of E. coli JM 83 host cell.
