Conference Paper's Strength:

Conferences are good venues for disseminating information and for discussing new results with colleagues. A contribution at a conference usually involves writing and submitting an abstract which is then reviewed and either accepted or rejected. Conference papers are written with the goal of being accepted to the conference, where your results are presented to the community, usually as an oral presentation, a poster presentation, or a tabled discussion. Conference papers are typically published in collections called "proceedings". Attending a conference is a very expensive means of getting a publication and this is not always guaranteed.

A journal paper does not involve attending an event.  The author write the paper, based on author guide, and submit it to the target journal. The review process for journals does not have a fixed deadline or schedule. However, instead of conferences that typically have only accept/reject decisions, journals typically have a rolling review schedule and reviewers can opt to ask the authors for revisions. As the journal paper is peer reviewed, it is considered a more valuable publication and is generally more difficult to get accepted.

Obviously reputed Journal papers.

It seems to me that what you, and I, should do is publish a paper, then present the ideas at conferences. A paper or a conference presentation alone is not enough to get your ideas accepted.

I think Han Ping Fung is right, Conferences are a good school for young scientists and researchers: "Good training ground for novice researchers that want to conduct research, write & publish papers / thesis as well as presentation before audience / thesis examiners during viva etc."

The publication of articles in serious scientific journals requires the author (s) to gain experience.

Hi Dear Han Ping Fung

thanks for useful infomation and I agree with you.

Hi Dear Anton

thanks for your comment.

I can describe Journals as a static method of transferring science meanwhile conference as a dynamic method, I preferred indexed journals, by the way I do agree with Dr. Han Ping Fung.

Hi Emad

thanks for your comment and your define is very fantastic.

Thank you very much my colleague Dr. Vahid,

I just right now posted this reply from the mechanical engineering point of view.

Regards, Emad (mechanical engineer).

In my understanding, majority of Journal and Conference papers are more concerned about advertising than about the real scientific contribution. Recently, I'm increasingly inclined to the fact that any Open Discussion in a wide audience (e.g. as in Researchgate) is a very valuable scientific contribution on a given topic to be "successful to transfer science to researchers". From my experience, I can say absolutely honestly that I try to find any truth (on a given topic or paper) in "hot" discussions, in which opposing points of view are presented. Comparing all points of view, I do my own conclusions. In my opinion, this is the only correct way to evaluate the scientific contribution of any paper. Using this oppurtinity, I want to raise the following question:

Could Science Blockhain became a modern IT tool to evaluate Real Science Contribution of any paper?

 Thanks for sharing the question. Colleagues have provided interesting responses. Concerning the main question of the thread, both journal papers and conference papers may be considered as successful ways ''to transfer science to researchers''. However, to me, the more successful way for this transference is journal papers with a prerequisite; not to be published in scientific journals of questionable quality.

Thanks for the question. In my university and other promotions in higher institutions, higher scores are given to journal papers than conference papers. Most times, conference papers meets a wider review audience in comparison to the few peer reviewers for journal papers. Yet, the modalities for conference paper attendance is not very robust as many conference organizers usually put a premium on number of attendance and papers to scrutinze. Afterall, the intricacies of the paper Will be discussed and improved before their possible inclusion in the published conference proceedings, thus, reducing the level of rejection to a minimal degree. On the other hand, journal paper submission should be heightened to the brim otherwise it may face possible rejection (high) for rigorous journals.

I think both of them have their strengths which must be appreciated as such. Researchers must not be influenced by the premium the promotions board in an institution place on each of these category of academic papers otherwise their good imports would be confused and even thwarted. The researcher must weigh the paper in the light of the best platform to shape the thoughts expressed in the paper to deepen their usefulness to the global academic community. 

Thanks
