It is my pleasure to see that the journey of PCIU Journal is continuing at the desired pace with the publication of volume 7 Issue (1 & 2) 2020. Indeed, it is a long, arduous but fruit-bearing venture. This volume contains as many as ten articles in the field of business, science and technology and other related subject areas. 
The articles of PCIU journal has been chosen by following the principles and guidelines enacted by the PCIU. The editorial board have conducted a meeting to scrutinize and reviewed the submitted articles and the selected articles were sent to reviewers. The authors were asked to revise their articles in light of reviewer's comments (whenever needed). The revised articles were further reviewed and checked by the editorial board members before going for final publication. However, it is the honorable readers who would judge the quality of the articles. 
I sincerely express my heartfelt thanks and congratulate the authors who have submitted their articles to be published in this journal. I would also like to express my sincere appreciation to the members of editorial board, the reviewers and all others involved in the process of publication of this journal for their commendable contribution. 
I also express my heartfelt gratitude to Prof. Dr. Nural Anwar, Hon’ble VC of PCIU for his relentless support and co-operation who took much trouble to get this journal published. the editorial board is greatly indebted to the chief patron Mr. A.
