Development status of the Korean Journal of Child Studies 4 years after the suggestions made in 2016

Objective: In the first issue of 2016 of the Korean Journal of Child Studies (KJCS), development strategies were proposed. The aim of the present study was to examine the changes made in response to each proposal and to suggest steps for further improvement. Methods: Changes in the characteristics and status of the journal from 2016 to 2020 were described, and new suggestions for further development strategies were proposed. Therefore, this article is a follow-up study of past data. Results: Among the development strategies proposed in 2016, the following aspects improved: specific aims and scope, official ISO abbreviations, open access declarations, international-level layout, manuscript editing, detailed instructions to authors, and digital standards including Journal Article Tag Suite XML. However, further improvements remain to be made with regard to changing the journal title, obtaining permission to use others' measurement tools, requiring statements of institutional review board (IRB) approval and informed consent, ensuring the long-term tenure of an editor-in-chief, and internationalizing the editorial board membership. The 2015 Web of Science impact factor was calculated as 0.009, while that of 2019 was 0.04. In contrast, the number of cites per 2 years in Scopus rose from 0.03 in 2015 to 0.07 in 2019. Conclusion: The above results showed that digital standards have been implemented perfectly. However, articles should specify whether permission was received to use measurement tools and whether IRB approval and informed consent were obtained. The language is recommended to be changed to English to broaden the readership and to increase citation frequency by other international journals

研究目标：《韩国儿童研究学报》（Korean Journal of Child Studies, KJCS）2016年首期刊发了期刊发展策略倡议。本研究旨在检视针对各项倡议所实施的修订举措，并提出后续完善方案。
研究方法：本研究梳理了该期刊2016至2020年间的办刊特征与发展现状变化，并提出了新的期刊发展策略优化建议，因此本文属于基于既往数据的追踪研究。
研究结果：2016年提出的发展策略中，以下维度得到了优化：明确的办刊宗旨与范围、官方ISO标准缩写、开放获取声明、国际化版面编排、稿件编辑规范、面向作者的详细投稿指南，以及包括期刊文章标签套件XML（Journal Article Tag Suite XML）在内的数字化办刊标准。但仍有部分维度有待进一步完善：期刊名称变更、获取他人测量工具使用许可、要求作者提供机构审查委员会（Institutional Review Board, IRB）审批证明与知情同意书、保障主编长期任职，以及实现编辑委员会成员的国际化。2015年Web of Science影响因子为0.009，2019年升至0.04；与之相对，Scopus数据库的两年期被引频次从2015年的0.03增长至2019年的0.07。
研究结论：上述结果表明，数字化办刊标准已得到全面落实。但仍需在刊发稿件中明确标注是否获得测量工具使用许可，以及是否取得机构审查委员会审批与知情同意。建议将期刊出版语言变更为英语，以拓展读者群体，并提升国际期刊的引用频次。
