OA journal publishing has steadily increased its relative share of all scholarly journal articles by about 20%-30%. The 'Gold' OA, often preferred by readers, refers to journal articles which are more widely available through the journal's web site immediately. This study analyzed funder and university's policy for paying APCs in implementing a Gold OA. In recent years there have been a number of attempts in the UK and Europe to stimulate more systematic arrangements for paying APCs, leading funders have clearly established arrangements in place. Also OA fund made by major universities in North America provides publisher with APCs. On the other hand, it is still in early stages in paying with gold OA requirements from Korean funders and universities. The funders have a 'Green' OA policy, such as upload the article accepted version to their online platform. Although it varies by field, many Korean authors are publishing in international journals. Their articles' impacts would rise when they are published as gold OA. Therefore, funders and universities need to pay attention to gold OA publishing and set up subsidies for APCs which are required by OA or hybrid journal publishers.

This study empirically analyzed the proportion and method of Open Access (OA) in Korea, China, Japan, the United States, United Kingdom based on the Web of Science (WoS) papers. In addition, through the verification of the moderating effect, it was verified whether there is a difference in the effect of the amount of citation depending on the maturity of OA according to the countries or academic fields. As a result of the analysis, the proportion of OA was the highest in the UK at 62.7%, and the lowest in China at 38.0%. Second, the UK and US had a high proportion of indicators through self-archiving and APC-based Gold Hybrid, while only the Gold indicators were found to be prominent in China and Korea. Third, in the UK, US and Japan, the higher the proportion of OA, the greater the effect of inducing the citations. However, Korea (B=-0.00003, p<0.01) and China (B=-0.00001, p<0.01) showed the opposite direction. In addition, in most academic fields, the OA proportion had an effect of inducing citation, but a negative effect was found in the engineering field (B=-0.00002, p<0.01).

We report results of selection-bias-free approaches to the analysis of the impact of open access (OA) models on citation metrics. We studied reference groups of Gold and Green OA articles and the group of non-OA (Paywall) articles with the new functionality of the Web of Science Core Collection database, the InCites platform of Clarivate Analytics, and the Dimensions database of Digital Science. For each reference group we obtained the values of the percent of cited articles and citation impact and their dependence on the depth of the citation period. Different research fields were analyzed in two schemas of the InCites platform. We report the higher values and growth rates of the citation metrics: citation impact and %Cited, in the OA reference groups over the Paywall group. The Green OA articles demonstrate the highest values of citation metrics among all the OA models. Dependence of the value of citation impact on citation period follows linear law with R2 values close to 0.9-1.0. The overall annual growth rates of citation impact of the Green OA, Gold OA, and the Paywall articles, k equal, respectively, 3.6, 2.4, and 1.4 in Dimensions and 4.6, 3.6, and 2.3 in the Web of Science Core Collection. We suppose that earlier results reported for the articles in pure OA journals vs. articles in Paywall journals were affected by the high citation impact of the Green and Hybrid OA articles that could not be elucidated in the Paywall journals at that time.

This study aims to review the possibility of OA to international journal articles cited by researchers of the library and information science field in Korea. For this, the international journal articless cited to the articles (1,543) of the Korean Society for Information Management were collected, and the investigation was carried out regarding the OA policy of the international journals and the status of journals that can be open to the public through the OA according to the OA policy. In addition, this study analyzed the actual accessibility by utilizing the OA finders (Google Scholar, Unpaywall, OA Button). The analysis result indicated that the majority of the international journals were using the green OA policy. Also, 1,476 journal articles which is 95.4% of the total international journal articles were allowed to be accessed officially with the OA. The results of reviewing the actual accessibility rate of the journal articles open to the public through the use of the OA finders indicated that accessibility was up to 68% when using Google Scholar, and the maximum accessibility rate was 72% when mixing the OA finders. Among the OA finders, Google Scholar had the greatest OA accessibility rate, but it was desirable to mix the OA finders in order to expand the OA accessibility rate to the maximum level.

In a situation where OA papers are increasing, POI, which indexes how open the research activities of individual researchers are, is drawing attention. This study investigated the existence of OA papers and the OA method published in international academic journals by domestic LIS researchers, and derived the researchers' POI based on this. In addition, by examining the relationship between the POI index and the researcher's amount of research papers, the research sub field, and the foreign co-authors, it was analyzed whether these factors are relevant to the researcher's POI. As a result, there were 492 papers by 82 researchers whose OA status and method were normally identified through Unpaywall. Second, only 20.7% of papers published in international journals were open accessed, and almost cases were gold and green methods. Third, there were many papers in text mining in medical journals, and the papers opened in the green method are open in institutional repositories of foreign co-authors or transnational subject repositories such as PMC. Third, the POI index was relatively higher for researchers in the field of informetrics, machine learning than other fields. In addition, it was analyzed that the presence or absence of overseas co-authors is related to OA.

Purpose: Laparoscopic appendectomy (LA) has become a gold standard for children even in complicated appendicitis. The purpose of this study was to compare the postoperative surgical site infection rates between laparoscopic and open appendectomy (OA) group in pediatric complicated appendicitis. Methods: A total of 1,158 pediatric patients (age ${\leq}$ 15 years) underwent operation for appendicitis over a period of 8 years. Among these patients, 274 patients (23.7%) were diagnosed with complicated appendicitis by radiologic, operative and pathologic findings, and their clinical outcomes were retrospectively analyzed. Results: Of the 274 patients with complicated appendicitis, 108 patients underwent LA and 166 patients underwent OA. Patients in the LA group returned to oral intake earlier (1.9 days vs. 2.7 days; p<0.01) and had a shorter hospital stay (5.0 days vs. 6.3 days; p<0.01). However, rate of postoperative intra-abdominal infection (organ/space surgical site infection) was higher in the LA group (LA 15/108 [13.9%] vs. OA 12/166 [7.2%]; p<0.01). Readmission rate was also higher in the LA group (LA 9/108 [8.3%] vs. OA 3/166 [1.8%]; p<0.01). Conclusion: The minimally invasive laparoscopic technique has more advantages compared to the open procedure in terms of hospital stay and early recovery. However, intra-abdominal infection and readmission rates were higher in the laparoscopy group. Further studies should be performed to evaluate high rate of organ/space surgical infection rate of laparoscopic procedure in pediatric complicated appendicitis.

Plan S is a policy that mandates research papers supported by specific funders such as the European Community be published in open access journals. The funder supports APC to researchers, providing a chance to advance the era of gold open access, and is expected to bring significant changes to the scholarly publishing ecosystem. This study explored the impact of Plan S from the perspective of each stakeholder of the scholarly publishing ecosystem, such as funders, academic societies or publishers, authors, and libraries, through a review of previous studies. In addition, the status of Korean gold open access publishing and position for each stakeholder were identified through the collected data analysis. As a result of the analysis, the share of publishing gold open access journals in Korea was 22%, which was less than 26% worldwide. Korean funding agencies were predicting and preparing for the impact of Plan S. On the other hand, Korean academic societies produce about 70% of all papers, but there are not many open access papers except medicine (51%). The response of the Korean library was not sufficient, and it contrasted with the activities of librarians in the U.S. that actively provide research support services based on the research lifecycle. It was suggested that Korean libraries should also actively try to change the role of librarians; advising researchers to plan open access publishing in grant project applications, consulting on copyrights, and so on. This study identified the background, principles, and impact of Plan S policy that would be effective in 2021 and examined the response situation in Korea. This study is valuable in that it served as the necessary basis for revitalizing the academic publishing ecosystem in Korea.

A bacterial pathogen, Pseudomonas syringae pv. actinidiae (Psa), is a causal agent of kiwifruit bacterial canker worldwide. Psa biovar 3 (Psa3) was first detected in 2011 at an orchard in Dodeok-myeon, Goheung-gun, Jeonnam Province in Korea. In this study, we present the results of an epidemiological study regarding Psa3 occurrence on kiwifruit orchards in Korea for the period of 2013 to 2015. Since the first detection of Psa3 in 2011, there was no further case reported by 2013. However, Psa3 was rapidly spreading to 33 orchards in 2014; except for three orchards in Sacheon-si, Gyeongnam Province, most cases were reported in Jeju Island. Entering 2015, bacterial canker by Psa3 became a pandemic in Korea, spreading to 72 orchards in Jeju Island, Jeonnam, and Gyeongnam Provinces. Our epidemiological study indicated that the first Psa3 incidence in 2011 might result from an introduction of Psa3 through imported seedlings from China in 2006. Apart from this, it was estimated that most Psa3 outbreaks from 2014 to 2015 were caused by pollens imported from New Zealand and China for artificial pollination. Most kiwifruit cultivars growing in Korea were infected with Psa3; yellow-fleshed cultivars (Yellow-king, Hort16A, Enza-gold, Zecy-gold, and Haegeum), red-fleshed cultivars (Hongyang and Enza-Red), green-fleshed cultivars (Hayward and Daeheung), and even a kiwiberry (Skinny-green). However, susceptibility to canker differed among cultivars; yellow- and red-fleshed cultivars showed much more severe symptoms compared to the green-fleshed cultivars of kiwifruit and a kiwiberry.

This research provides a quantitative analysis on research articles published in PLoS ONE, a multidisciplinary open access journal, by authors affiliated with Korean institutions. Korean authors published more than 6,500 research ariticles in the mega journal between 2006 and 2019. Korea is ranked the top 11th place in terms of article publishing in the journal. Most articles by Korean authors are concentrated in the biomedical fields. In recent years, the overall production of PLoS ONE has decreased as authors migrated to competing mega journals such as Scientific Reports and BMJ Open. The change might have been affected in part by the delay in the review period and the dropping impact factor score. The open access share of the Korean PLoS ONE authors of more than 10 articles hovers around 30%. However, there is a significant variation among researchers reaching up to 50% discrepancies. Among altmetrics provided by PLoS ONE, the saves are highly correlated with the views and the citations. On the contrary, the shares show low correlation with other use metrics. A follow up, survey questionnarie based research involving researchers who have published in PLoS ONE is planned in order to investigate author motivation and experience in the review process.
