Editorial

We are together with you again with the fourth issue of the fifth publishing year of JEMS. This issue consists of ‘'engine performance'', ‘'ship design'', ‘'burnout level of seafarers'', ‘'submarine resistance'', ‘'emergency evacuation operation'', ‘'ship wave bending moment'', ‘' dangerous cargo operations'' and ‘'liquid cargoes transportation'' subjects along with seventeen precious researches. Our efforts to increase the national and international recognition of our Journal still continue. JEMS has been evaluated by Index Copernicus, which is internationally recognized index, for three years. I am pleased to mention that JEMS has gradually increased its score within this period (46.94 (2014), 68.39 (2015), 93.00 (2016)).
