Postantibiotic effects (PAE) refer to suppression of the bacterial growth following limited periods of exposure to an antibiotic and subsequent to the removal of the antibiotic agent. Fusobacterium nucleatum and Porphyromonas gingivalis are Gram-negative anaerobic bacteria associated with several periodontal diseases. In this study, postantibiotic effects (PAE), postantibiotic sub-MIC effect (PA SME) and sub-MIC effect (SME) of antibiotics on F. nucleatum ATCC 25586 and P. gingivalis W50 were investigated. The PAE was induced by 10X the MIC of antibiotic and antibiotic was eliminated by washing. The PA SMEs were studied by addition of 0.1, 0.2 and 0.3X MICs during the postantibiotic phase of the bacteria, and the SMEs were studied by exposition of the bacteria to antibiotic at the sub-MICs only. Amoxicillin, doxycycline and tetracycline induced PAE for F. nucleatum ATCC 25586 and P. gingivalis W50. But metronidazole and penicillin induced PAE for only F. nucleatum ATCC 25586. Metronidazole and doxycycline induced PA SME and SME for both species of anaerobic bacteria used in this study. The PA SME values for both strains were substantially longer than the SME values. The present study showed the existence of PAE, PA SME and SME for various antibiotics against F. nucleatum ATCC 25586 and P. gingivalis W50.

우리나라에서의 산불은 대부분 인간에 의해서 발생하며, 최근 그 피해가 산림과 관련산업에만 국한되지 않고, 도시와 근교의 산불 유입과 그로 인한 도시의 피해가 발생하고 있는 실정이다. 본 논문에서는 2013년 봄철, 도시근교에서 발생하여, 산림 인접 가옥과 시설물에 피해를 발생시킨 포항시와 울주군의 사례를 모의 재현하고, 그 피해 강도와 범위를 비교함으로써, 산불의 피해 재현과 산림 내, 산림 인접지의 위험지 예측에 적용하고자 하였다.
