JOTSE ' S NEW CHALLENGES

As a matter of fact, if we observe JOTSE's monthly evolution we can state that November and December are the months with more papers submissions as the average increases (as shown in Table 1) In particular, in year 2018 we have had twice as much articles than in preceding years. In addition, there has been a steady rise in the total number of article submissions and such increase could be due to the fact that JOTSE has been indexed in SCOPUS since November 2015 and that we have started receiving more articles from foreign countries and not so many from Spain.

As we can observe in Figure 1, the objective of steady growth has been accomplished throughout these 8 last years.

As a matter of fact, if we observe JOTSE's monthly evolution we can state that November and December are the months with more papers submissions as the average increases (as shown in Table 1) In particular, in year 2018 we have had twice as much articles than in preceding years.In addition, there has been a steady rise in the total number of article submissions and such increase could be due to the fact that JOTSE has been indexed in SCOPUS since November 2015 and that we have started receiving more articles from foreign countries and not so many from Spain.
As to the articles published (included in Table 2), we can observe the evolution of the volumes/issues and articles published in the years (2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018).In 2018, we have increased the number of articles published regularly and we have kept the number of special issues, namely two.This is directly proportional to the volume of articles received.When analysing the percentage of rejected articles we can see that in year 2016 it was 36 %, in 2017 the figure rose up to 69 % and in 2018 it was 64%.It is important to mention here the role of JOTSE's reviewers who do their job with much rigor and out of their generosity.In fact, we could not publish our journal without their help and, therefore, we thank them all for this here.We can observe in Figure 2 the good opinion of our "authors/users" on the quality of our reviewers and their intention to recommend JOTSE Journal.
In this vein, if we analyses JOTSE's internationalisation as to visits to its website is concerned (one of our challenges) we can observe in Table 3 the 10 countries that have visited JOTSE's website more frequently in the last 4 years.In 2018 the first position was for the United States, the Philippines was second and (only in the third position) appeared Spain with 13.29%.This is a clear evidence that the degree of internationalisation of JOTSE Journal is increasing.Hence, we can observe more internationalisation in the articles and authors who published in our latest issues, which was one of our main goals in JOTSE Journal.Last but not least, we would like to thank Dr Noelia Olmedo-Torre, from the Polytechnic University of Catalonia (UPC, Barcelona Tech) for her job and teamwork within the Editorial Board in the last few years and we wish her great success in the new stage she has just started.On the other hand, we welcome Dr. Jasmina Berbegal-Mirabent, from the Universitat Internacional de Catalunya (UIC), Dr. Juan José Escribano from the Universidad Europea de Madrid (UEM) and Dr. Emilio Rallón from the Universitat Politècnica de València (UPV), who are willing to face JOTSE'S new challenges and goals as our new team members.
