The prior studies in the citation analyses of Korean natural science and engineering journals found that they have cited SCIE (Science Citation Index Extended) journals significantly. This research investigated the citation impact of the Korean natural science and engineering journals (from 2009 to 2014) toward SCIE journals in terms of JCR (Journal Citation Reports) ranking changes. First, this research analyzed the cited numbers and citation age by subject and journal through the citation analysis of the cited SCIE journals. Second, this research created the co-citation networks of journals and subjects by using co-citation analysis of SCIE journals. Based on the same method, we also assessed the network centrality measures and compared the citation numbers in each journal. Third, this research analyzed the changes in journal ranking in SCIE journal citation index by reflecting the citations of Korean natural science and engineering journals into JCR. Our results indicate that engineering has higher cited numbers, smaller peak-time, and cited half-time values than natural science. These results mean the journal articles in engineering are more quickly consumed and decreased than natural science journals, respectively. Second, this research visualized the co-citation network of SCIE journals and subject areas based on the Korean journals, and it also measured the network centrality in journals and subjects. Third, this research found that the existing journal Impact Factor (IF) (2 years) has been changed significantly if we apply the Korean journal citations into JCR in 2014, and there are significant changes in JCR journal rankings in engineering and natural science. This research shows the impact of Korean journals on SCIE journals, and the results of this study can be used for the future evaluation of journals. The practical implications were presented for Asian countries as well as Korea to develop their own JCR rankings and for their academic libraries to provide better scholarly services.

国家期刊对SCIE期刊JCR排名的引用影响分析

之前对韩国自然科学和工程期刊引文分析的研究发现，它们对SCIE（Science Citation Index Extended）期刊的引用率很高。本研究调查了韩国自然科学和工程期刊（2009 年至 2014 年）在 JCR（期刊引文报告）排名变化方面对 SCIE 期刊的引用影响。首先，本研究通过对SCIE被引期刊的引文分析，按学科和期刊分析了被引数量和被引年龄。其次，本研究利用SCIE期刊的共引分析建立了期刊和学科的共引网络。基于相同的方法，我们还评估了网络中心性度量并比较了每个期刊的引用数。第三，本研究通过将韩国自然科学和工程期刊的引用反映到 JCR 中，分析了 SCIE 期刊引用指数中期刊排名的变化。我们的结果表明，与自然科学相比，工程学具有更高的被引数、更小的峰值时间和被引半衰期值。这些结果意味着工程学期刊文章分别比自然科学期刊更快地被消耗和减少。其次，本研究基于韩国期刊对SCIE期刊和学科领域的共引网络进行了可视化，并衡量了期刊和学科的网络中心度。第三，本研究发现，如果我们在 2014 年将韩国期刊引文应用到 JCR 中，现有期刊影响因子（IF）（2 年）发生了显着变化，并且JCR期刊在工程和自然科学方面的排名有显着变化。本研究展示了韩国期刊对SCIE期刊的影响，本研究结果可用于未来期刊的评价。为亚洲国家和韩国发展自己的 JCR 排名和他们的学术图书馆提供更好的学术服务提出了实际意义。
