Abstract	Purpose This study aimed to investigate the changes that occurred in journal and article publishing during the noncontact period that started in 2020 due to COVID-19. Methods The integrated journal list in Journal Citation Reports (JCR) 2017–2021 and the search results of Web of Science were analyzed using pivot tables in Microsoft Excel. The articles, citations, impact factor (IF), publishers, open access (OA) status, and compound annual growth rate (CAGR) were investigated using the data. Results The CAGRs of articles, citations, and IFs in JCR journals increased throughout the COVID-19 pandemic. Moreover, the increase in OA articles was accompanied by a decreasing share of subscription articles. The top 20 journals in JCR-SCIE (Science Citation Index Expanded), based on the number of articles, accepted OA policies and showed a strong influence, accounting for 7% to 9% of all articles. MDPI and Frontiers were OA publishers included among the top 10 publishers. Large publishers maintained their competitiveness through mergers and acquisitions with OA publishers. Due to the rapid distribution of OA and early access articles as part of the international response to overcome COVID-19, the CAGRs of citations and IFs increased more than that of articles, and the publication and use of journal articles have become more active. Conclusion The publication and use trends in JCR journals analyzed herein will provide useful information for researchers’ selection of journals for article submission, analyses of research performance, and libraries’ journal subscription contracts.

Abstract	Purpose This study explored changes in the journal publishing market by publisher and access type using the major journals that publish about 95% of Journal Citation Reports (JCR) articles. Methods From JCR 2016, 2018, and 2020, a unique journal list by publisher was created in Excel and used to analyze the compound annual growth rate by pivot tables. In total, 10,953 major JCR journals were analyzed, focusing on publisher type, open access (OA) status, and mega journals (publishing over 1,000 articles per year). Results Among the 19 publishers that published over 10,000 articles per year, in JCR 2020, six large publishers published 59.6% of the articles and 13 publishers 22.5%. The other publishers published 17.9%. Large and OA publishers increased their article share through leading mega journals, but the remaining publishers showed the opposite tendency. In JCR 2020, mega journals had a 26.5% article share and an excellent distribution in terms of the Journal Impact Factor quartile. Despite the high growth (22.6%) and share (26.0%) of OA articles, the natural growth of non-OA articles (7.3%) and total articles (10.7%) caused a rise in journal subscription fees. Articles, citations, the impact factor, and the immediacy index all increased gradually, and the compound annual growth rate of the average immediacy index was almost double than that of the average impact factor in JCR 2020. Conclusion The influence of OA publishers has grown under the dominance of large publishers, and mega journals may substantially change the journal market. Journal stakeholders should pay attention to these changes.

Abstract	The demilitarized zone (DMZ), a military buffer zone between South and North Korea, is an ecological treasury free from human interference and a core ecological axis of the Korean Peninsula, making its conservation crucial. However, surveys have been insufficient because of restricted civilian access and ecosystem fragmentation. We aimed to investigate the ecological value of the DMZ and the regional characteristics of plants. A flora survey was conducted along the iron fences in the South Korean DMZ and analyzed by region. We recorded 1,051 vascular plant taxa comprising 121 families, 484 genera, 936 species, 25 subspecies, 81 varieties, and 9 formae. The region requires habitat protection because of the presence of 36 rare and 38 endemic taxa, and 35 floristic target species of Stage IV or higher. Invasive alien plants require further monitoring because 89 invasive taxa were recorded. Changes in military facilities or barren land operations can threaten habitats or create habitat edges. Biological resources, including plants, should be monitored for a multifaceted evaluation of the DMZ ecosystem value. Habitat restoration research and conservation activities should be conducted by establishing an environmental database linking environmental conditions with native plant habitats.

Abstract	Purpose There is somewhat of a difference between understanding the open access (OA) concept and practicing it by stakeholders. OA articles are mainly published by gold and hybrid OA journals, but the OA status may be confusing depending on the target databases. This study investigated the OA status of journals and articles and evaluated the extent to which OA2020 (publishing 90% of articles as OA) was achieved. Methods This study collected OA data by combining 2014-2019 data from Journal Citation Reports at the journal level with Web of Science at the article level. Finally, 12,449 journals were analyzed focusing on gold and hybrid OA journals, and progress towards the goal of OA2020 was evaluated. Results Even though 80.4% of Journal Citation Reports journals were gold and hybrid OA journals, only 20.9% of the articles were OA (gold OA journals, 16.6%; hybrid journals, 4.3%). The compound annual growth rate of the total articles was 4.7%, that of OA articles was 16.4%, and that of subscription articles was only 1.7%. Among the subscription journals, 77.4% had shifted to become hybrid journals, but only 5.2% of their articles were OA. Therefore, the hybrid journals were at the very early stage of OA publishing. Conclusion Considerable progress must still be made to achieve the goal of OA2020. The influence of OA publishing will eventually expand and therefore, librarians should take interest in OA publishing for the library services.

Abstract	Purpose The number of open access (OA) journals is rapidly increasing, and it is very important for librarians to understand the influence of OA journals on the research community. This study investigated the influence of the OA journals listed in Journal Citation Reports (JCR) based on various indicators. Methods The data for this study were prepared by combining the JCR 2014 to 2019 journal list with the number of hybrid OA articles obtained by searching the Web of Science. Each journal’s JCR indicators and article processing charge were added. The influence of OA journals was compared according to OA type, whether they were published by large publishers, and whether they were top gold OA journals. Results Gold OA journals remained weaker in terms of JCR indicators than hybrid journals. However, the top 20 gold OA journals, accounting for 27.0% of all OA articles in JCR 2014 to 2019, were superior in all JCR indicators. The top three OA publishers (MDPI, BioMed Central, and Public Library of Science) showed potential for development despite concerns regarding poor journals. The top three subscription publishers were very active in OA publishing, but their actual share of hybrid OA articles (Elsevier, 5.1%; Springer, 10.1%; and Wiley, 12.4% in JCR 2019) was still insufficient. Conclusion Some gold OA journals showed high competitiveness and even the possibility for development beyond traditional journals. The transition of subscription journals to hybrid journals was found to be at the early stage. In light of these findings, librarians should continue monitoring the influence of OA journals.

Abstract	Background and Objectives The aim of the present study was to investigate the effects of a combination of crushed cartilage and thin silastic sheet for patients with a risk of septal perforation during septoplasty. Materials and Methods A total of 195 people who underwent septoplasty surgery at Dong-A University Hospital from January 2019 to December 2020 were enrolled retrospectively. Among 195 people, our surgical method was provided for those with damage to both septal mucosa. The cartilage was collected, crushed with the cartilage crusher, and inserted between perforated mucosa. After the cartilage insertion, a 0.254-mm-thin silastic sheet was designed to cover both sides of the perforated septal mucosa. Next, a penetrating suture was placed. After thin silastic was applied on both mucosa, a 1-mm-thick silastic sheet was inserted on both sides of the nasal cavity and penetrating sutures were placed on the anterior and inferior septum. The operation concluded after packing both sides of the nasal cavity using non-absorbable packing material. The packing was removed on the second day after the operation, and the nasal cavity condition was checked every week. Thick silastic sheets were removed 5 days after surgery, and thin silastic sheets were maintained until both septal mucosa healed. Results Of nine total cases, only one 78-year-old male experienced septal perforation at the cartilage portion two months after surgery. In this case, no other action was taken to cover the perforation site because he reported no symptoms or discomfort during the 9 months after surgery. In the other eight cases, both septal mucosa healed completely, and there were no complications. Conclusion This method with crushed cartilage and silastic sheets to fill the defect after septal surgery is thought to help prevent postoperative perforation at no additional cost, and further research is needed.

Abstract	Efficient water electrolysis is one of the key issues in realizing a clean and renewable energy society based on hydrogen fuel. However, several obstacles remain to be solved for electrochemical water splitting catalysts, which are the high cost of noble metals and the high overpotential of alternative catalysts. Herein, we suggest Ni-based alternative catalysts that have comparable performances with precious metal-based catalysts and could be applied to both cathode and anode by precise phase control of the pristine catalyst. A facile microwave-assisted procedure was used for NiO nanoparticles anchored on reduced graphene oxide (NiO NPs/rGO) with uniform size distribution in ~1.8 nm. Subsequently, the Ni-NiO dual phase of the NPs (A-NiO NPs/rGO) could be obtained via tailored partial reduction of the NiO NPs/rGO. Moreover, we demonstrate from systematic HADDF-EDS and XPS analyses that metallic Ni could be formed in a local area of the NiO NP after the reductive annealing procedure. Indeed, the synergistic catalytic performance of the Ni-NiO phase of the A-NiO NPs/rGO promoted hydrogen evolution reaction activity with an overpotential as 201 mV at 10 mA cm −2 , whereas the NiO NPs/rGO showed 353 mV. Meanwhile, the NiO NPs/rGO exhibited the most excellent oxygen evolution reaction performance among all of the Ni-based catalysts, with an overpotential of 369 mV at 10 mA cm −2 , indicating that they could be selectively utilized in the overall water splitting. Furthermore, both catalysts retained their activities over 12 h with constant voltage and 1000 cycles under cyclic redox reaction, proving their high durability. Finally, the full cell capability for the overall water electrolysis system was confirmed by observing the generation of hydrogen and oxygen on the surface of the cathode and anode.

Abstract	Despite the increasing interest in RF (Radiofrequency) therapy, little is known about its effectiveness for low back pain (LBP). The aim of this study was to investigate the effectiveness of 4.4-MHz RF diathermy compared to ultrasound (US) in patients with LBP. One-hundred-and-eighteen patients with LBP were randomized with RF ( n = 62) or US ( n = 56). Investigator and subjects were blinded to the treatment group. Either RF (4.4 MHz, 45 W/cm 2 ) or US (1 MHz, 2 W/cm 2 ) was applied for 10 to 15 min, 3 times per week for 4 weeks. The primary outcome was the Oswestry Disability Index (ODI, %). Secondary outcomes were numeric rating scale (NRS), Biering–Sorensen test, up-and-go test, successful pain relief, and successful functional improvement. Clinical outcomes were evaluated prior to intervention (baseline), and at 4 and 12 weeks after treatment. There were no significant differences between the groups regarding baseline demographic and clinical characteristics. Both groups observed a significant improvement of ODI (%), NRS, Biering–Sorensen test, and up-and-go test at 4 and 12 weeks after treatment ( p < 0.05); however, no significant differences were found between groups. The RF group showed a higher proportion of successful pain relief at 12 weeks after treatment than the US group ( p = 0.048). The RF diathermy showed favorable results in pain reduction, improvement of function, mobility, and back muscle endurance. Compared with US, RF diathermy obtained slightly better perception of patients in pain relief at 12 weeks after treatment. The results from this study indicated that 4.4-MHz RF diathermy can effectively be used as a conservative treatment option for patients with LBP.

Abstract	The inhibition of the aberrant differentiation of tendon-derived stem cells (TDSCs) is a major target for the regeneration of damaged tendon tissues, as tendinopathy can be caused by the aberrant differentiation of TDSCs. We investigated whether the possible aberrant differentiation of TDSCs can be prevented by using adequate inhibitors. TDSCs extracted from chemically induced tendinopathy and injury-with-overuse tendinopathy models were cultured with 18α-glycyrrhetinic acid (AGA) and T0070907 to block osteogenic differentiation and adipogenic differentiation, respectively. The optimal dose of AGA decreased the osteogenic-specific marker Runx2 (Runt-related transcription factor 2), and T0070907 blocked the adipogenic-specific marker peroxisome proliferator-activated receptor gamma (PPARγ) in mRNA levels. We also found that AGA induced tenogenic differentiation in mRNA levels. However, T0070907 did not affect the tenogenic differentiation and regenerative capacity of TDSCs. We expect that optimal doses of AGA and T0070907 can prevent tendinopathy by inhibiting osteogenic and adipogenic differentiation, respectively. In addition, AGA and T0070907 may play important roles in the treatment of tendinopathy.
