The purpose of this study was to isolate and identify bacteria from the 4 patients with non-odontogenic infectious lesions (mucormycosis, chronic inflammation from wound infection, and two actinomycosis) and determine their antimicrobial susceptibility against eight antibiotics. Bacterial culture was performed under three culture conditions (anaerobic, CO2, and aerobic incubator). The bacterial strains were identified by 16S rRNA gene (16S rDNA) sequence comparison analysis method. For investigating the antimicrobial susceptibility of the bacteria against eight antibiotics, penicillin G, amoxicillin, tetracycline, cefuroxime, erythromycin, clindamycin, vancomycin, and Augmentin® (amoxicillin + clavulanic acid), minimum inhibitory concentration (MIC) measurement was performed using broth microdilution assay. Nosocomial pathogens such as Enterococcus faecalis, Klebsiella pneumoniae, Bacillus subtilis, and Neisseria flavescens were isolated from mucormycosis. Veillonella parvula, Enterobacter hormaechei, and Acinetobacter calcoaceticus were isolated from chronic inflammatory lesion. Actinomyces massiliensis was isolated from actinomycosis in parotid gland. Capnocytophaga ochracea was isolated from actinomycosis in buccal region in anaerobic condition. There was no susceptible antibiotic to all bacteria in mucormycosis. Tetracycline was susceptible to all bacteria in chronic inflammation. C. ochracea was resistant to vancomycin and penicillin G; and other antibiotics showed susceptibility to all bacteria in actinomycosis. The results indicated that the combined treatment of two or more antibiotics is better than single antibiotic treatment in mucormycosis, and penicillin is the first recommended antibiotic to treat actinomycosis.

본 연구의 목적은 출발시각기준 실시간 링크통행시간 추정정보의 질을 평가하는 것이다. 이에 본 연구는 통행시간 정보의 질을 정확성(추정오차)과 신속성(시간처짐) 측면에서 평가하였다. 그리고 통행시간 정보의 질과 링크길이 및 혼잡수준과의 관계를 규명하였다. 분석결과, 출발시각기준 실시간 링크통행시간 추정정보의 정확성과 신속성은 서로 상충관계임을 알 수 있었다. 또한 정확성을 나타내는 '추정오차' 는 계통오차(systematic error)와 혼잡수준을 반영하는 평균자승오차(MSEE)로 구성되는 것으로 분석되었다 시간처짐은 '최소시간처짐', '혼잡에 의한 시간처짐', '갱신간격에 의한 시간처짐'으로 구분하여 평가하였다. 이를 실제 AVI자료에 적용한 결과, 링크길이와 혼잡수준에 관계없이 추정오차가 5%일 때, 시간처짐은 약 10분 정도 발생하는 것으로 나타났다.
