The goal of this study was to investigate how spectrographic features of ultrasonic vocalizations (USVs) in rats vary among individuals and behaviors. Eighteen pairs of rats were allocated to individual pair cages. Each pair's behaviors and vocalizations were recorded during the 900s a known cage-mate was returning to the cage. The effects of individuals, behaviors, and the interaction between individuals and behaviors ($individuals{\times}behaviors$) were tested on the duration and peak frequencies. There was difference in the duration and peak frequency: i) among individuals (p<0.0001 and p<0.0001, respectively); ii) among behaviors (p = 0.0667 and p<0.0001, respectively); iii) among individuals${\times}$behaviors (p<0.0001 and p<0.0001, respectively). The frequency of ultrasonic vocalizations changed with a frequency ranging from 40 to 71 kHz which were emitted by individuals, whereas the frequency of ultrasonic vocalizations changed with a frequency ranging from 60 to 70 kHz which were emitted by behaviors. The peak frequency of call on 'contact' behavior was lower than that of call on other behaviors, but call duration of call on 'contact' was longer than on other behaviors. Especially, 40 kHz calls were found on 'contact' and 'other' behaviors. We suggest that ultrasonic vocalizations need to be subdivided and the effects of individuals and behaviors must be considered to assess emotional state of rats because these may influence the features of ultrasonic vocalizations.

1993년부터 한국 서해안의 새우 양식장에서는 양식새우의 대량폐사가 일어났다. 외부증상은 두흉갑과 표피에 흰 반점이 나타났고 어류주화세포에는 배양되지 않았다. 열($50^{\circ}C$) 및 강산(pH 3)에는 쉽게 실활되었으나 강알카리(pH 11)에는 내성이 강했다. 바이러스의 입자 형태는 Rod Shaped한 형태를 보였다. 바이러스 단백질의 분석결과는 Hypodermal Hematopoietic Necrosis Baculovirus(HHNBV)와 유사했고 바이러스 핵산분석 결과는 약 114kb로 Penaeid Acute Viremia(PAV)와 유사했다.

본 연구는 델타-이미노레블린산(ALA)의 급여가 산란계의 생산성 및 계란 품질에 미치는 영향에 대해 알아보기 위하여 시험을 실시하였다. 사양 시험은 30주령 ISA Brown 144수를 공시하였으며 28일간 실시하였다. 시험 설계는 1) CON (기초 사료), 2) 0.05(기초 사료 + ALA 0.05%) 3) 0.1(기초 사료 + ALA 0.1%) 및 4) 0.2(기초 사료 + ALA 0.2%)로 4개 처리를 하여 처리당 4반복, 반복당 12수씩 완전 임의 배치하였다. 전체 사양 시험 기간 동안, 델타-아미노레블린산의 첨가 수준이 증가함에 따라 산란율의 감소가 나타났으나, 0.2% 첨가 수준에서 다시 증가하는 경향을 나타내었다(quadratic effect, P=0.01). 난중은 델타-아미노레블린산의 첨가 수준이 증가함에 따라 무게가 증가하였다(linear effect, P=0.01; quadratic effect, P=0.01). 난황색은 전체 사양 시험 기간 동안, 0.1% 첨가 수준까지 난황색이 높아지다가 0.2% 첨가 수준에서 낮아지는 경향을 나타내었다(quadratic effect, P=0.03). 델타-아미노레블린산의 첨가 수준이 증가함에 따라 혈액 내 hemoglobin 농도가 유의적으로 증가하였다(linear effect, P= 0.01). 결론적으로, 산란계에 델타-아미노레블린산의 급여는 난중 및 난황색 그리고 혈액 내 hemoglobin 농도를 증가시키는 것으로 사료된다.

다양한 미생물들로부터 유래한 cellulase 중에서, 특히 장내 단백질 가수분해효소에 안정한 Clostridium thermocellum 균주 유래의 endoglucanase를 선별하였다. 그 후 그 유전자의 자체 프로모터에 의해 발현되는 재조합 Lactobacillus용 발현벡터를 구축하였고, 그 발현벡터를 pSD1이라 명명하였다. 이 발현벡터를 L. bulgaricus와 L. plantarum 균주에 각각 전기천공법을 이용하여 형질전환시키는데 성공하였으며 그 재조합 균주들로부터 endoglucanase 효소역가를 조사한 결과 각각 배지 상층액에서 0.12, 0.144 U/ml로 조사되었다. 한편 이들 균주들의 생균제로 갖추어야할 특성인 내산성, 내담즙성 및 항생제내성 여부를 조사한 결과, 이들 균주들은 모두 pH3과 같은 산성 조건하에서도 안정하였으며, 내담즙성에 있어서는 특히 L. plantarum 균주의 경우 0.3, 1% 의 oxgall에서도 안정하였다. 또한 항생제 내성을 조사한 결과 두 균주 모두 amikacin, gentamicin, kanamycin, colistin에 저항성이 높은 것으로 나타났다.

Incidence of retained placenta in dairy cows was investigated in 120 parturitions. Prior to calving, cows were allotted into four groups; 1) control, 2) the infection of Vitamin E (500 IU), 3) the injection of selenium (40 mg), and 4) the infection of Vitamin E (500 IU) and selenium (40 mg). Selenium (Se) and Vitamin E were injected intramusculary 20 d prior to the estimated calving date. No effects of Se or Vitamin E administration alone was observed for number of service per conception, conception rate, and estrus rate (p > 0.05). But the Vitamin E administration with Se significantly (p < 0.05) reduced the incidence of retained placenta and the days required for calving the first service. Incidence of retained placenta was not significantly (p > 0.05) influenced by parity, but it was significantly (p < 0.01) influenced by season, especially, increased during July and August. Concentration of Se in plasma was not significantly (p > 0.05) changed during peripartum period whether the treatment. The results of this study on retained placenta suggest that this disorder will be reduced by the administration of Se and Vitamin E prior to calving in dairy cows.

Deconstructionism is a philosophical stream in the latter half of 20'th century which goes against western metaphysics and tries to deconstruct the dualism e.g. eastern/west-ern man/woman. Its main concepts are 'indi-vidual' 'other' 'difference' 'restoration of the repressed' 'decentralization' 'Today it shows strong influences in literature art, and other social fields. This study investigated inner meanings and exterior forms represented in clothing on the base of Jacques Derrida's theory in order to re-search modes of deconstruction in is. And it compared clothing with architecture among other genres of art in order to discover similarities between through and modes of art in a certain period. For illuminating concept of deconstruction I referred to the literatures of preceding studies and for deconstruction's characteristics in both clothing and architec-ture I referred work's collection book $\ulcorner$collec-tions$\lrcorner$ and other related books dealing from 1960's to this point. As a rsult there are four modes of decons-truction in both clothing and architecture as follows; 1) Differenance which is a concept of the dif-ference in time and space as being trace. 2) In termeaning of meanings which is not present in reality but re-interpreted a new in the future. 3) Interxtuality in which a texte is not alone but with others 4) Dis.De phenomenon in which distortion and fragmentation forms occur as the result of the denial of perfection and reson. There are characteristics of modes of de-construction in clothing as follows; 1) Differance; R.Gigli, P. Rabanne. G.Bersace, V.Westwood are representatives of the cloth-ing which is combined with the past the pres-ent and the future or is re-viewed as the clothing of the past in the present point of view. J. Watanabe R. Dawakubo I miyake are representatives of the clothing which is out-date but re-viewed in the sense of recollec-tion and re-usage. 2) Intermeaning of meanings: R. kawakubo I, Miyake Y,Yamamoto are representatives of the clothing which is incomplete but re-interpreted in the future and appears to be new-fashioned according to ways of bnding wearing throwing on and tying J.C. Castel-bajac K.Hamnett S.Sprouse are representa-tives of the clothing which is made up of ab -stract forms scribbling or symbolic letters which appears to be different according to view-point of observers. 3) Intertextuality ;J.P.Gaultier K.Hamnett, Comme des Gar ons are representatives of intertextuality of gender which avoids the 여-ality of man/woman J.P Gaultier G,Versace J. galliano are representatives of the intertex-tuality of time place and occasion which mixes temporality extensity and purposiveness. J.P Gaultier G,Versace are representatives of the intertextuality of coordination which combines items different in image purpose and use. P.Rabanne A,Courr ges R,Gernreic I,Miyake are representatives of the intertextuality of mat-ter which uses heterogeneous matter different from cloth. 4) Dis.De-phenomenon: R, Kawakubo I.Mi-yake J.P.Gaultier are representatives of the de-composition which discloses distortion and exag-geration of form through destructing the estab-lished way of construction J.Galliano R.Kawa-kubo Devota Y Lomba arte representatives of the decentring which restores the repressed and the alienated on the one hane and shows front-centrality on the other. Comme des Gar ones is representative of the discontinuity because of which right and left up and down are not in har-mony with one another. J,Galliano J.P,Gaultier T,Mugler are representatives of the disruption by way of which one makes one's body exposed through intentional slashes or holes. As a consequence deconstructionism enabled us to investigate similarities between through of deconstruction and modes of art interms of diffrance Intermeaning of meanings intertextuality and Dis De-phenomenon. And we found that deconstruction was a phase of development in that it as a all-comprising and multiple concept tries to pursue the new through deconstruction.
