The market of dental materials industry in Korea will over 10 bilians $. If think concern of world market, we can know the possibility of market growth. In Korea, the technique of dental materials industry is low status. Then, special items income advanced countries. But advanced countries had been developed dental materials industry into high beneficial. Otherwise, Daegu Kyungbuk have several good points in dental materials industry. 1st, national dentisty university and three dental lab. college supplies abilitable human resources. 2nd, the possibility of support on basic industrial technology. Finally, the possibility of selection & attraction from many dental company. Then if Daegu Kyungbuk would be select & supported of dental materials Industrial special region, it can be think that will empower local economy, further national constitutional power. So we propose following three points, 1st. the deeper study on righteous of Daegu Kyungbuk dental materials industrial specialization. 2nd. investment on R & D of the region dental materials industrial. final, the support of venture circle.

느타리버섯(원형1호 느타리) 자실체의 부위별로 지방산 조성을 조사한 결과 linoleic acid는 갓부위에서 가장 높았고 대부위로 갈수록 낮아지는 경향이었고 stearic acid와 palmitic acid는 대부위로 갈수록 증가하는 경향이었다. 생육시기별 지방산조성은 oleic acid의 경우 버섯원기형성 후 $11{\sim}12$일 까지는 점차 증가하다가 이후부터는 감소하는 경향을 보였고 linoleic acid와 불포화지방산대비 포화지방산의 비율은 원기형성 후 $3{\sim}4$일까지는 증가하다가 그 후부터는 감소하는 경향을 나타내었다.

In this study, homogenized mixture of tubercle and pulmonary lymph node showed up tuberculin(PPD) positive dairy cattle was inoculated in experimental animal, and was cultured on medium(Lowenstein Jensen medium, 3% Ogawa). The results obtained through the survey were sumerized as follows ; 1. In experimental animal, goat and rabbits were decreased body weight(25∼28%) and died in 90 days with severe pathogenicity. Rats are slight pathogenicity. 2. Goat, rabbits and rats showed up severe lesions In lung, rabbits was also lesions other organs (kidney, appendix, ileocecum, and I lymph node). 3. Mycobacterium was grown between 5 weeks and 8 weeks on Lowenstein Jensen medium and 3% Ogawa medium. 4. Biochemical test of Mycobacterium cultured on medium was that niacin, nitrate reduction, tween 80 hydrolysis and catalase test were negative, but that urease test was positive. Therefore it was Mycobacterium bovis (M. bovis).

This study was carried out the antimicrobial resistance of staphylococcus aureus isolated from bovine mastitic milk, chickens, korean native cattle, korean native goats, pigs, dog and mice in northern area of kyongbuk. The result were summarised as follows ; A total of 149 S aureus were isolated from bovine mastitic milk, chickens, korean native cattle, korean native goats, pigs, dog and mice. In 80 isolates of S aureus from bovine mastitic milk, 60% of isolates revealed resistance to penicillin and ampicillin, 19% to gentamicin, 6% to tetracycline. In 36 isolates of S aureus from chickens, 72% of isolates revealed resistance to tetracycline, 58% to penicillin and ampicillin, 42% to streptomycin, 31% to lincomycin, 25% to norfloxacin, 22% to gentamicin. In 17 isolates of S aureus from korean native cattle, 100% of isolates revealed resistance to penicillin and ampicillin, 88% to lincomycin, 76% to tetracycline. 2 MRSA were isolated from the isolates of S aureus from bovine mastitic milk and revealed multi-drug resistance.

A considerably high rate of abnormal deliveries of unknown etiology was observed among dairy cattles from November 1988 to February 1989 and Korean native tattles from January to April 1990. The abnormal deliveries consisted of abortions, stillbirths and calf deformities refers to as congenital arthrogryposis hydranencephaly (AH )syndrome. In order to know the level of Akabane antibody of dairy cattle raised in Kyungbuk province, serum neutralization test was conducted with Akabane virus(OBE-1 strain) and HmLu(Hamster lung) cell line. The results were summarized as follows. 1. During 4 months(Nov. 1988-Feb. 1989), abortion (3 heads), stillbirth(1 head) and congenital abnormalities(13 heads) of newborn were occurred in 17 dairy cattles raised in Kyungbuk province. 2. During 4 months(Jan.-Apr.1990), stillbirth(2 heads) and congenital deformities (13 heads) of newborn were occurred in 15 Korean native tattles raised in Kyungbuk province. 3. In Fev, and Apr. 1990, 1,005 dairy cattles at 99 farms were investigated on the actual condition of possessing Akabane antibody. The result was that 1,000 heads (99.9%) in 1,005 dairy cattles reacted as positive condition in Akahane antibody. The antibody titer was from 4 to over 256. 4. 189 heads (18.8%) of 1,005 dairy cattles werw below antibody titer 8 and 816 heads (81.2%) were over 16. 5. Akabane antibody titer of east coast legions(Pohang Yeongil etc) was all over 16, that of internal legions (Yeongiu, Andong. etc) was relatively low, The result suggest that the vaccination for Akabane disease will be unnecessary for the time being because of possessing higher antibody titer reaction except the newly introduced cattle and Akabane virus was widely disseminated in kyungbuk province during the summer months in 1987 or 1988.

최근 국내 큰느타리버섯 재배농가가 증가하면서 병해의 발생이 문제점으로 나타나고 있다. 본 연구에서는 큰느타리 버섯의 자실체에 발생하는 푸른곰팡이 병반으로부터 Penicillium sp.균을 분리하여 동정하였고 생리적 특성을 조사하였다. 분리된 Penicillium sp.균의 형태적 특성을 조사한 결과, 분생포자는 타원형이고 크기는 $2.3{\sim}3.4{\times}2.6{\sim}3.2\;{\mu}m$였다. 분생자병은 균사로부터 one-stage branch 모양을 형성하고, metulae는 $2{\sim}4$개로 크기가 $10{\sim}l8{\times}2.5{\sim}3.0\;{\mu}m$이며, phialides는 플라스크상이고 크기가 $9{\sim}13{\times}2.2{\sim}2.8\;{\mu}m$였다. Czapek 배지에서 배양할 경우 $25^{\circ}C$에서 7일에 균총이 21 mm 성장했으며, 균총의 색은 회녹색이었다. 이상과 같은 형태 및 배양적 특징으로 공시균을 Penicillium corylophilum로 동정하였고 이균을 상처접종하였던바 $6{\sim}7$일만에 재배농가에서와 동일한 증상을 나타내었다.
