Drug-resistant strains isolated from animals have have become an increasingly serious problem because of their resistance to antimicrobial agents and as potential donors of their R-Plasmid to sensitive strains. A total of 129 strains of C. jejuni isolated from pigs and chickens were examined for the susceptibility to 10 antimicrobial agents. Minimal inhibit-ory concentration(MIC) ranges of antimicrobial agents to C. jejuni isolates were○0.2 to 12.5㎍/㎖ for gentamicin and chloramphenicol, ○0.2to25㎍/㎖ for kanamycin and nalidixic acid 0.2 to○400㎍/㎖ for streptomycin. Resistance rates of C. jejuni were showed to in order of cephalothin(100%) rifampin(86%), streptomycin(74.4%), tetracycline(58.1%), erythromycin(24.8%) and ampicillin(3.1%), all of the strains were sensitive to chloramphenicol, gentamicin and kanamycin. The drug resistance patterns of 87 chicken isolates to C. jejuni to 10 antimicrobial agents were showe different patterns, and Cep Sm Re Tc pattern and Cep Sm Re pattern were relatively common, and also 42 pig isolates were showed 5different patterns and Cep Sm Tc pattern were most frequeint and Cep Sm Re Tc pattern were most frequent. A total of 57 isolates of C. jejuni were subjected to test for the presence of plasmid DNA of the isolates examined. 68.4% of the isolates were noted to harbor plasmid DNA. Plasmid occurence rate from pigs and chickens were 70.6% and 62.%, respectively. The strain with a large molecular weight plasmid, ranging from 30-78Md were identified as tetracycline resistant.

손글씨를 인식하기 위하여 여러 방면의 노력들이 존재하여왔다. 손글씨를 인식하기 위한 예로는 일어 영어 숫자 등등 다양한 방면의 논문들이 존재하고 있다. 다만 어린아이들과 같은 경우는 인식에 대한 어려움이 존재하기에 이러한 것을 극복하기 위하여 우리는 Deep learning 기술을 사용하였다 사용한 기술은 SLR, ANN, CNN 총 3가지 기법을 사용하여 정확도를 측정하였고 그 결과 SLR은 91% 두 개의 층을 더 넣어준 것은 93% CNN은 95%로 가장 높은 성능을 보였다.

A total of 277 specimens from cow skin, Korean native cattle skin, silage, bulk milk and cow feces were examined for the incidence of Listeria species. The bacterial isolates was selected on LiCl-phenylethanol-moxalactam agar plates after the cold enrichment in FDA-EB at 4℃ for 7 days and identified by several biochemical, mobility, and CAMP test. Prevalence of L. innocua was found to be 58.6% in cow feces, 17.1% in corn silage, 13.3% in Korean native cattle skin, 5.9% in cow skin, and 4.0% in bulk milk. L. monocytogenes was isolated from 4.3% in corn silage and 2.0% in cow skin but was not found in the skin and feces of cattle, and bulk milk specimens. Of 10 L. monocytogenes isolated, 7 strains were classified into serotype 4, and 3 strains was untypable.
