Saya kira Anda benar bahw waktu diskusi
yang paling leluasa adalah apabila kita melakukan poster session.
Akan tetapi para calon pemakalah kelihatan-nya lebih senang
untuk melakukan Oral Presentation , Apakah hal ini al disebabkan nliai
kredit - nya yang lebih rendah ?
Si Abah
bravo, pak awang! terimakasih atas infonya.
