The title is too long. Should only be 12 words but go ahead and submit it. See what happens. Keywords are never the same words in the title. They should always be different and limited to 6 words/short phrases.I changed this. There are now 5,300 words. Much more complete than the Thai version sent. So you know, a complete paper with a results/discussion section should be approximately 8,000 words when you prepare the FINAL MODEL paper later. The conference wants to use the term ‘LITERATURE REVIEW’. For paper 2, I deleted many of paper 1’s citations and researched new citations for you. This makes the paper must more publishable when submitting both at the same time. The METHODOLOGY section was also made stronger than the first paper and more complete. As this is a conceptual paper, there is no results and discussion section in the paper. The model names now match the words in the paper perfectly. It was also redesigned to make it more ‘beautiful’. There are now 35 references in paper 2. Most are new and different from the 1st paper. Again, this makes your 2nd paper much stronger.
