When outbound mobility programs and service learning align in pre-service teacher education
Anne Power,Son Truong,Tonia Gray,Greg Downey,Tim Hall,Benjamin Jones 서울대학교 교육연구소 2017 Asia Pacific Education Review Vol.18 No.3
This project sought to investigate the learning that comes about from the intersection of outbound mobility experience programs (OMEs) with service learning in pre-service teacher education settings. The aim of the program of international service learning in the case study was to encourage pre-service teachers to rethink potentially ethnocentric assumptions. The guiding research question was, ‘What outcomes ensue from the combination of OMEs and service learning for pre-service teachers?’ The focus of the paper was on OMEs that took place in China and Malaysia. Findings included that the combined program aided development of global mindedness, learning by being there, teacher experience in a new context and the development of a professional identity in the participating students.
Effect of Cadmium on Radial Growth and Dry Mass Production of Ectomycorrhizal Fungi
김창기,Sally Anne Power,John Nigel Berridge Bell 한국생태학회 2004 Journal of Ecology and Environment Vol.27 No.5
The sensitivity to Cd of three ectomycorrhizal fungi, Paxillus involutus, Suillus bovinus and Rhizopogon subcaerulescens, was assessed and compared in terms of radial growth and dry mass production, using both agar and liquid culture. The radial growth of S. bovinus and R. subcaerulescens was significantly reduced at the lowest concentration (0.1 mg Cd/L). The 50% effective concentration (EC50) values calculated from radial growth rates of the ectomycorrhizal fungi showed that the sensitivity of the fungi to Cd was greatest in S. bovinus and lowest in R. subcaerulescens. Cadmium addition also significantly decreased dry mass production of the ectomycorrhizal fungi. The sensitivity of the fungi to Cd in terms of dry mass production, was greatest in S. bovinus and lowest in P. involutus. Higher growth rates of P. involutus and melanisation of R. subcaerulescens appeared to contribute to reduced Cd toxicity.

The sensitivity to Cd of three ectomycorrhizal fungi, Paxillus involutus, Suillus bovinus and Rhizopogon subcaerulescens, was assessed and compared in terms of radial growth and dry mass production, using both agar and liquid culture. The radial growth of S. bovinus and R. subcaerulescens was significantly reduced at the lowest concentration (0.1mg Cd/L). The 50% effective concentration (EC$_{50}$) values calculated from radial growth rates of the ectomycorrhizal fungi showed that the sensitivity of the fungi to Cd was greatest in S. bovinus and lowest in R. subcaerulescens. Cadmium addition also significantly decreased dry mass production of the ectomycorrhizal fungi. The sensitivity of the fungi to Cd in terms of dry mass production, was greatest in S. bovinus and lowest in P. involutus.
