Rapid Detection of SdhBP225F and SdhBH272R Mutations in Boscalid Resistant Botrytis cinerea Strains by ARMS-PCR

SdhBP225Fand SdhBH272R mutations have been found associated with boscalid resistance in Botrytis cinerea from strawberry in Shanghai, China. For rapid detection of two mutations, tetra-primers were designed and optimized to gain the relatively high accuracy and specificity based on the ARMS-PCR technique, by which resistance can be identified with different lengths of products on agarose gels. The tetra-primer ARMS-PCR systems for SdhBP225F and SdhBH272R were validated by 9 SdhB-squenced strains... -
Effects on G2/M Phase Cell Cycle Distribution and Aneuploidy Formation of Exposure to a 60 Hz Electromagnetic Field in Combination with Ionizing Radiation or Hydrogen Peroxide in L132 Nontumorigenic Human Lung Epithelial Cells

The aim of the present study was to assess whether exposure to the combination of an extremely low frequency magnetic field (ELF-MF; 60 Hz, 1 mT or 2 mT) with a stress factor, such as ionizing radiation (IR) or H2O2, results in genomic instability in non-tumorigenic human lung epithelial L132 cells. To this end, the percentages of G2/M-arrested cells and aneuploid cells were examined. Exposure to 0.5 Gy IR or 0.05 mM H2O2 for 9 h resulted in the highest levels of aneuploidy; however, no cells... -
To Be Conservative as a Disposition of Education: Familiarity, Freedom and Learning from the Perspective of Michael Oakeshott

Purpose: The purpose of this study is chiefly to interpret and clarify a traditionally notion of the conservative disposition concealed in liberal education by reviewing three basic concepts?familiarity, freedom and learning? from the perspective of Michael Oakeshott. Method: Firstly, we discover that there are two intractable crises in education on account of the observation of history and current situations. The first relates to the sustainability of the conservative disposition and the second... -
‘Tutee Resistance’ during Writing Tutorial as a Part of Negotiation: Case Studies on Two Korean EFL Students
Lee Hyeon-Ji, Cho Sookyung 한국교육학회 교육학연구 20 Pages
한국교육학회 교육학연구 2022, 60권 3호 2 29-48 (20 pages)
This study investigates how ‘tutee resistance’ works as a part of negotiation between writing tutors and tutees by comparing two Korean EFL (English as a Foreign Language) students. So far, the resistance that tutees have shown during writing tutorials has been considered as a dispreferred practice in the framework of conversational analysis (Waring, 2005). However, this study adopts a sociocultural view that negotiation is key to tutor-tutee interactions and that it starts when there occurs a... -

미소결함을 가진 금속체에 교류자기장을 인가하면 결함부근에는 와전류의 분포가 달라져 이에 의해 금속체를 관통하는 교류자기장은 결함부근에서 차이를 가진다. 이 교류자기장을 비정질 와이어로 된 센서헤드로 측정하여 센서헤드의 유기전압 크기로부터 결함 유무를 검출하는 방법에 대해 검토하였다. 비정질 와이어는 Co-based재료로 자왜가 거의 0이며 고투자율 자성체이고 비정질 와이어는 길이가 15mm, 직경이 100$mu extrm{m}$인 원주형 자성체이다. 실험대상 금속체로 0.5mm의 단일 직선 갭을 가진 두께 1mm의 동판과 0.1mm의... -
