Annulation of N-allyl-2-ethynylaniline derivatives easily afforded the corresponding 2-substituted 3-allylindole derivatives in good to excellent yields using P,olefin ligand/palladium catalst systems.

The purpose of this study is to understand who user' property affects the ability to manipulate a digital camera. The N-back task, the action control scale, usability test, structural test, functional test, protocol analysis and some questioner are used to understand user' distinction. The relationships among each property and performance were cleared by correlation analysis. As a result, functional models about the camera are most important to use well.
