Abstract
From Editor’s Desk…..

At the outset let me express my gratitude to our beloved Rector Dr.Khalid Bin Saad Al Meqrin and Vice Rector for Graduate Studies and Scientific Research Prof. Dr. Mohammad Bin Abdullah Al-Shaaya for the trust endowed upon me.

MJHS is proud to bring forth its third issue of Vol 7:2019 on the occasion of the National Day of Saudi Arabia. All of us renew loyalty and allegiance and show the love to our generous homeland and wise leadership. MJHS wishes all the stakeholders and readers a Happy 89th National Day.
The editorial team strives hard to publish the issues on time; I express my sincere thanks to the international panel of experts and new team of editorial assistants for their efforts to improve the publication process of MJHS office.

Authors who are submitting their research in MJHS are encouraged to enrich their scientific contributions by plagiarism checking and get their manuscripts professionally edited prior to submission; especially the authors for whom English is a second language. There are many editing services available that can help the authors improve the scientific and grammatical writing of their manuscripts. However, the language editing does not guarantee publication and any costs incurred are the sole responsibility of the author.

The editorial team would like to thank all authors, reviewers, readers for their continuous support for the success of MJHS.

Dr. Khalid Mohammad Alabdulwahhab
Editor in Chief
