The present study was conducted to investigate the isolation frequency, biochemical properties and antimicrobial susceptibility of B. bronchiseptica isolated from slaughtered pigs during the period from March to December, 1992. in Kyeonggi province. A serological survey for antibody of B. bronchiseptica in 200 slaughtered pigs was carried out by agglutination and tetrazolium reduction methods. The results were summarized as follows; 1. From 80 slaughtered pigs, 27(33.8%) case were isolated and all isolate strains were resistant to Penicillin, Streptomycin, Chloramphenicol, Tetracycline and Ampicillin, while the majority of them were susceptible to Gentamicin, Cloxacin, Colistin, Neomycin, and Kanamycin. 2. Incidence of B. bronchiseptica antibody in 200 slaughtered pigs were measured by agglutination and tetrazolium reduction methods. Agglutination method was shown 38(19%) of 200 with a titer of below 1:20 and 20(10%) of 200 with a titer of above 1:640. Tetrazolium reduction method was observed 33(16.5%) of 200 with a titer of below 1:20 and 32(16%) of 200 with a titer of above 1:640. 3. LSD analysis indicated that the difference of the responses between agglutination test and tetrazolium reduction test was not significant.

It is said that the technical high school have changed with national economical policy since liberation. The fact was that the technical high school had educational system of vocational school of foreign college but had not distinct educational aims because of dearth of educational process and facilities. Under this condition, with view to making professional education have systematic and synthetic contents, the technical high school must come out past irrational contents and accept ideal system for the better. Accordingly, as the method for activating architectural education of the technical high school, it analyzes the present school curriculum, the present situation of facilities and students thought by opinionnaire, Then it draws out new educational direction from comparing domastic department of architecture with foreign. Therefore it presents new educational system in accordance with the new direction.

Serial ultrasonographic examinations were daily performed from 15 days after ovulation until parturition to determine the time of first detection and ultrasonographic appearance of the fetal and extra-fetal structures in pregnant 10 Maltese, 10 Yorkshire Terrier, 15 Shih-tzu, and 10 Miniature Schnauzer bitches, respectively. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0ng/ml. The gestational length was (range: ) days and the geatational length was no statistically significant difference among bitches (p>0.05). The initial detection of the extra-fetal structures were; gestational sac at days , zonary placenta at days , yolk sac membrane at days , yolk sac tubular shape at days , and amniotic membrane at days , respectively. The time of the first detection of the extra-fetal structures were no statistically significant difference among bitches (p>0.05). The initial detection of the fetal structures were; embryo initial detection at days , heartbeat at days , embryo bipolar shape , fetal movement at days , limb buds at days , stomach at days , urinary bladder at days , skeleton at days , and kidney at days , respectively. The the time of the first detection of the fetal structures were no statistically significant difference among bitches (p>0.05). These results indicate the evaluation of the time of first detection and ultrasonographic characteristics of the gestational structures might be useful for pregnancy diagnosis, estimating fetal age, embryonic resorption, fetal monster, abnormal fetal growth and fetal viability, respectively.
