본 연구는 생태교육 프로그램 운영 및 개발과 교수에 대한 학습방법에 필요한 기초자료를 제공하고자 생태학습에 관한 어린이집 교사들의 인식 및 실태에 있어 파생되는 문제 및 개선점을 알아보고, 생태기술력의 영향으로 국가경 쟁력이 미래유아교육의 발전과 유아들의 생태적 사고 능력 및 창의성 기르기의 중요성과 질 높은 교육의 기회가 적절한 시기에 제공함으로써 유아교육 발전을 위한 생태교육에 있어 교사양성 및 현직교사연수를 국가차원에서 이루어져야 할 것이다.

Methicillin-resistant Staphylococcus aureus (MRSA) is a substantial contributor to morbidity and mortality. In search of a natural products capable of inhibiting this multidrug resistant bacteria, we have investigated the antimicrobial activity of brazilein (BRZ) isolated from Caesalpinia sappan L. (Leguminosae) against 8 different strains of Staphylococcus aureus (S. aureus). New antimicrobial activity was found using the minimum inhibitory concentrations (MICs), broth dilution as well as checkerboard method. Against the 8 strains, the minimum inhibitory concentrations of BRZ were in the range of 62.5-500μg/mL. From those results we performed the checkerboard test to determine the synergism of BRZ in combination with Hygromycin-b (HgB) against 4 strains. The combined activity of BRZ and HgB against 4 strains resulted in a fractional inhibitory concentrations index (FICI) ranging from 0.18-0.5. The effect of BRZ with HgB was found to be synergistic. We found that BRZ reduced the MICs of HgB. BRZ and HgB could lead to the development of new combination antibiotics against MRSA infection.
