I have a ecological background, but there is an excellent books about SEM: Grace, J. Structural Equation Modeling and Natural Systems. He offers philosophical and some statistical advice. If you know R, there is a package ('sem'), which I used, but you can see also 'Lavaan' package (http://www.r-bloggers.com/first-steps-with-structural-equation-modeling/)
Dear Juliano, thank you so much for your advice and help. Thank you once again. Do you know university and institution in South Korea where the training is provided on this topic? thank you.
