  • According to the increases the standard of living of the people, requirements for building environments are also being diversified. The fungus that occurred the building is not good the health of occupants as well as undermine the value of the building. However, chemical antimicrobial agent contain ingredients harmful to human body and it has an impact on indoor air quality. Therefore, the use of natural antimicrobial material is strongly required. In this study, the fungal reproductive inhibit capacity was evaluated by using mortars with natural antimicrobial material.

  • 화력발전소에서 발생하는 유연탄 Bottom ash(BA)는 고온에서 연소 되고 남은 재이다. 고온에서 구워진 재료이기 때문에 맥반석과 같은 기능이 있을 것으로 사료되어 연구를 시작하였다. 최근 일반 모르터보다 황토, 맥반석 등이 재료로 들어가서 원적외선, 항균, 항곰팡이, 탈취, 조습 기능이 있는 모르터의 수요가 늘어가는 추세이다. 유연탄 BA를 친환경 바이오 혼합소재로 활용하기 위한 친환경 바이오 BA 모르터를 일반 모르터와 각각의 기능성에 대해 비교 시험한 결과 원적외선 방사율이 약 $0.02{\times}10^2W/m^2$ 정도 높게 측정되었으며, 탈취 기능은 약 26% 이상 높게 측정되었다. 조습의 경우에도 친환경 바이오 BA 모르터가 일반 모르터보다 약 1.8배 우수한 효과를 가지고 있는 것으로 나타났으며, 국토해양부에서 제정한 흡 방습 건축자재 "양호"기준보다 10% 이상 뛰어난 것으로 나타났다.

  • We studied the photocatalytic functionality such as deodorant, antibacterial, fine dust collection efficiency of polyester-based non-woven fabric filter treated with self-actuated photocatalyst. According to UV/visible result, the UV-visible peak of visible-light responsive photocatalyst was found to be red shift at 420 nm sensitive in the visible light region. The deodorizing performance was shown to be reduced more than 80% even without dark conditions. Fine dust particles collection efficiency was shown to be excellent at the size of not only $2.5{\mu}m{\sim}10.0{\mu}m$ but also less than $2.5{\mu}m$. Also antimicrobial and antifungus was shown to be reduced more than 99.9%.

  • A screening test showed that lycorine exhibited significant antifungal activity against 24 pathogenic crop fungi at concentrations of 500 ${\mu}g/ml$ and 100 ${\mu}g/ml$, respectively. Fusarium graminearum was selected for antifungal mechanism studies by observing its mycelial morphology and investigating the variations in its conductivity. In addition, the substance absorption and metabolism of F. graminearum were explored. The mechanism was revealed as being one by which lycorine destroyed the cellular membrane and further influenced substance absorption and cell metabolism.
