Purpose: The purpose of this study was to analyze articles published in the Journal of the Korean Academy of Nursing (JKAN) between 2010 and 2019, along with those published in three international nursing journals, to improve JKAN’s international reputation. Methods: The overall characteristics of JKAN’s published papers and keywords, study participants, types of nursing interventions and dependent variables, citations, and cited journals were analyzed. Additionally, the keywords and study designs, publication-related characteristics, journal impact factors (JIF), and Eigenfactor scores of International Journal of Nursing Studies (IJNS), International Nursing Review (INR), Nursing & Health Sciences (NHS), and JKAN were analyzed and compared. Results: Among the four journals, JKAN’s score was the lowest in both the journal impact factor and Eigenfactor score. In particular, while the JIF of INR and NHS has been continuously increasing; JKAN’s JIF has remained static for almost 10 years. The journals which had cited JKAN and those which JKAN had cited were mainly published in Korean. Conclusion: JKAN still has a low IF and a low ranking among Social Citation Index (E) journals during the past 10 years, as compared to that of four international journals. To enhance JKAN’s status as an international journal, it is necessary to consider publishing it in English and to continuously improve the conditions of other publications.

Purpose: This year 2020 marks the 50th anniversary of the founding of the Korean Society of Nursing Science (KSNS). This study was aimed to explore development of caring and describe the 50 years of history of KSNS within the sociocultural context of Korea regarding academic footsteps, meanings, and implications for the future. Methods: This study used a historical research methodology using a literature review and bibliometric analysis. Relevant literature was reviewed and the published abstracts in the Journal of Korean Academy of Nursing (JKAN) were analyzed using VOSviewer. Results: Birth control and family planning in the 1970s was the main research topic. In the 1980s, the development of nursing concepts, theories, and philosophies was the mission of KSNS to extend the disciplinary boundary. In the 1990s, the progress of KSNS to become one of the woman-dominant healthcare professionals was the mission in the given period. Expanding the frontiers of KSNS to the extent of global standards was the undertaking of the nursing scholars in the 2000s. Lastly, in the 2010s, the quality and quantity improvement of KSNS and JKAN is expected to make our future even prosperous. The map visualization of the 50 years of research accumulation showed the comparable opposition of quantitative vs. qualitative research methodologies, equation modeling, and instrument development. Conclusion: These clusters of research demonstrates the efforts to make nursing evidence by Korean nursing scholars for the last five decades. The growth in the slope of KSNS and outcomes of JKAN are to carry on to an unimaginable extent in the future.
Plausibility of Local Currency Contribution to the CMIM
Soyoung Kim,Woongji Im 서울대학교 경제연구소 2020 Seoul journal of economics Vol.33 No.3
This study assesses the plausibility of local currency contribution to the Chiang Mai Initiative Multilateralization (CMIM) arrangement. First, we investigate the (net) demand for local currencies in foreign exchange reserves because introducing local currency contribution is efficient only when sufficient demand exists. The main results are as follows. i) Substantial demand exists for local currencies in foreign exchange reserves. ii) The size of the demand for local currencies in foreign exchange reserves is large in comparison with the size of the maximum withdrawal from CMIM. iii) Net demand for local currencies in CMIM tends to be positive. Second, the stability of local currencies is analyzed by calculating the exchange market pressure index because costs of local currency contribution to CMIM arrangements can be high if local currencies are unstable. The results suggest that several currencies of ASEAN+3 members are as stable as popular non-U.S. international currencies for various sub-periods. The results in terms of stability of the currency, internationalization of currency, and liberalization of capital account transactions, indicate that the Japanese yen, Chinese yuan, and Korean won could first be considered eligible for local currency contribution to CMIM arrangements. Overall, the results may support the idea of introducing local currency contribution to CMIM arrangements.
