Purpose - This study investigates the effects of going public on the innovation of KOSDAQ firms. Design/methodology/approach - This study uses firms that go public from 2007 to 2011 in Korea. We compare a firm's innovation performance over five years before and after IPO. Findings - We find that firm's innovation declines after an IPO. After going public, both the quality and the quantity of patents are decreased. However, this decrease is alleviated in high-tech industries or concentrated industries where innovation is expected to be more valuable. When comparing firms with venture capital(VC), which are more likely to window dress, to firms without VC, VC backing has no meaningful impact on changes of innovation. Research implications or Originality - As the KOSDAQ market was established to provide small and medium enterprises(SMEs) with funds for firm's investments and growth, it is necessary to verify whether the capital raised at the IPO encourages innovation. Thus, our study contributes to the literature by examining empirically whether an IPO boosts a firm's innovation.

The history of the APOCP/APJCP goes back to 1999 when a number of interested scientists joined together to form the organization and to launch a new journal to support cancer prevention research in the Asian-Pacific area. Since the initial Founding Conference, some six General Assemblies (GAs) and ten Regional Conferences (RCs) and Special Study Sessions have been organized. Already the decisions have been made for two further GAs and at least three RCs. As of the April issue of 2013, a total of nearly 3,700 papers have already been published in regular issues of the APJCP or special supplements. With support of the Korean National Cancer Center, housing the Chief Editorial Office, the journal is now including approximately 100 papers a month. Although it experienced a set-back by reduction in the Impact Factor (IF) from 1.29 in 2010 to 0.67 in 2011, there are good grounds to expect an improvement in 2012. However, the future of the APOCP/APJCP will continue to depend on its membership, making continuous efforts to attend our conferences and submit good quality manuscripts. It is particularly important to cite papers in the APJCP wherever possible, if the wish is for an IF commensurate with our long term aims. In that sense it is up to all authors, since the journal will continue to have a very positive ploicy towards accepting papers from all countries within the Asian-Pacific, with continue to varied levels of resources. The editorial team looks forward to your considered support. The APOCP also hopes to see you in person at future meeetings, so that you have a more active voice in deciding the best way forward in our cooperative enterprise.

Objective : This study was aimed to review the trend of clinical research articles of acupuncture and moxibustion from the year of 1995 to 2006. Methods : The retrieving and analyzing period were from January 1995 to July 2006. Articles were collected by retrieving Pubmed database. Search terms were as follows; 'Acupuncture', 'Acupuncture & Meridian', 'Moxibustion'. After reviewing articles by our pre-defined criteria, Correlation was assessed qualitatively between contents of the final selected articles and those of Korea Institute of Oriental Medicine. Results : The number of acupuncture research articles have increased with higher rate since the year of 2000. In the field of medical devices, the articles were sparsely existed. The percentage of clinical acupuncture research articles was 75%. However, in the category of Korean investigators' researches, it was 46%. Publications by Korean investigators were concentrated to several specific journals of which their impact factor were below 1 point. Conclusion : There needs more qualifying studies in acupuncture studies which are represented by impact factor in Journal Citation Reports. It is necessary to research and develop the medical devices quantatively rating the outcome of acupuncture trials. The secondary research, such as, systematic reviews, meta-analysis, would be a key approach to evaluate the effectiveness and safety of acupuncture treatments. Moxibustion research would be noticeable in regard to its historical effectiveness and its variable indications.

Many publishers tried flipping, or extensively changed their journals flipped. They considered that converting an established journal into OA journal is more attractive than launching an entirely new OA journal. After conducting a careful literature review, this study provided the background and current situations on flipping. There are flipped OA journals alive published by commercial publisher, society, university, and institute in the field of science and medicine. This study found the increased number of published articles after flipping, with 69% of 97 flipped OA journals in 2015 having impact factors. Also 92% of the journals experienced rising in ranking of impart factor, or achieved it for the first time. It was suggested that the roles of academic society, funding agencies, and universities when it comes to active flipping.

The availability and use (citedness) of Korean medical journals are measured based on the bibliometric data of 82 journals evaluated by the Korean Association of Medical Journal Editors between 1997 and 1999. A Korean medical journal is held on the average by one half of Korean medical libraries investigated. Only 10 journals (12.2%) are covered in any of 36 abstract and index databases in the field of medicine searchable through DIALOG. The journal self-citation rate is 3.402%. 1.092% of papers are cited at least once by SCI journal papers within 3 years after publication. The average SCI impact factor of Korean medical journals is 0.111, However, the impact factor of MEDLINE or SCISearch journals is 10 times higher. The results show that the Korean medical journals are not easily available domestically and internationally. They are hardly cited by Korean colleagues or by foreign scholars either.

The purpose of this study is to analyze the research fields constituting the knowledge structure of the Korean Studies by applying hierarchical clustering method to domestic journal papers in Korean Studies. We analyzed 3,800 papers containing Korean author keyword that were listed in 14 kinds of Korean Studies journals published in 2004-2013, which have average impact factor more than 0.5 in 2011-2013. The results of the analysis show that the central research fields are the subjects related to political & social problems based on Confucian ideas focusing on Neo-Confucianism (Seonglihak) and Realist School of Confucianism (Silhak), to the political situation associated with territorial division of the Korean peninsula, and to the history from the period of japanese colonialism to modern and contemporary. It has been also found that the temporal backgrounds of researches in domestic Korean Studies were related to the modern times and the Joseon Dynasty periods, rather than the time of the ancient and contemporary.

The study analyzed bibliometric data of papers published in Korea Citation Index (KCI) and Web of Science (WoS) journals from 2002 to 2021. After examining size differences of KCI and WoS domains in the number of authors, institutions, and journals to put publication and citations counts in perspective, the study investigated co-authorship patterns over time to compare collaboration trends of Korean and international scholars and analyzed the data at author, institution, and journal levels to explore how the influences of authors, institutions, and journals on research output differ across domains. The study also conducted frequency-based analysis of keywords to identify key topics and visualized keyword clusters to examine topic trends. The result showed Korean LIS authors to be twice as productive as international authors but much less impactful and Korean institutions to be at comparable levels of productivity and impact in contrast to much of productivity and impact concentrated in top international institutions. Citations to journals exhibited initially increasing pattern followed by a decreasing trend though WoS journals showed far more variance than KCI journals. Co-authorship trends were much more pronounced among international publication, where larger collaboration groups suggested multi-disciplinary and complex nature of international LIS research. Keyword analysis found continuing diversification of topics in international research compared to relatively static topic trend in Korea. Keyword visualization showed WoS keyword clusters to be much denser and diverse than KCI clusters. In addition, key keyword clusters of WoS were quite different from each other unlike KCI clusters which were similar.

Since information scientists have begun trying to quantify significant research trends in scientific publications, '-metrics' research such as 'bibliometrics', 'scientometrics', 'informetrics', 'webometrics', and 'citation analysis' have been identified as crucial areas of information science. To illustrate the dynamic research activities in these areas, this study investigated the major contributors of '-metrics' research for the last decade at three levels: nations, institutions, and documents. '-metrics' literature of this study was obtained from the Science Citation Index for the years 2001-2011. In this analysis, we used Pathfinder network, PNNC algorithm, PageRank and several indicators based on h-index. In terms of international collaborations, USA and England were identified as major countries. At the institutional level, Katholieke University, Leuven and the University of Amsterdam in Europe and Indiana University and the Office of Naval Research in the USA have led co-research projects in informetrics areas. At the document level, Hirsch's h-index paper and Ingwersen's web impact factor paper were identified as the most influential work by two methods: PageRank and single paper h-index.

Research on changes in research trends in academic disciplines is a method that enables observation of not only the detailed research subject and structure of the field but also the state of change in the flow of time. Therefore, in this study, in order to observe the changes of research trend in library and information science field in Korea, co-word analysis was conducted with Korean author keywords from three types of journals which were listed in the Korea Citation Index(KCI) and have top citation impact factor were selected. For the time series analysis, the 15-year research period was accumulated in 5-years units, and divided into 2003~2007, 2003~2012, and 2003~2017. The keywords which limited to the frequency of appearance 10 or more, respectively, were analyzed and visualized. As a result of the analysis, during the period from 2003 to 2007, the intellectual structure composed with 25 keywords and 8 areas was confirmed, and during the period from 2003 to 2012, the structure composed by 3 areas 17 sub-areas with 76 keywords was confirmed. Also, the intellectual structure during the period from 2003 to 2017 was crowded into 6 areas 32 consisting of a total of 132 keywords. As a result of comprehensive period analysis, in the field of library and information science in Korea, over the past 15 years, new keywords have been added for each period, and detailed topics have also been subdivided and gradually segmented and expanded.

This study investigates the development path and intellectual structure of data literacy research, aiming to identify emerging topics in the field. A comprehensive search for data literacy-related articles on the Web of Science reveals that the field is primarily concentrated in Education & Educational Research and Information Science & Library Science, accounting for nearly 60% of the total. Citation network analysis, employing the PageRank algorithm, identifies key papers with high citation impact across various topics. To accurately trace the development path of data literacy research, an enhanced PageRank main path algorithm is developed, which overcomes the limitations of existing methods confined to the Education & Educational Research field. Keyword bibliographic coupling analysis is employed to unravel the intellectual structure of data literacy research. Utilizing the PNNC algorithm, the detailed structure and clusters of the derived keyword bibliographic coupling network are revealed, including two large clusters, one with two smaller clusters and the other with five smaller clusters. The growth index and mean publishing year of each keyword and cluster are measured to pinpoint emerging topics. The analysis highlights the emergence of critical data literacy for social justice in higher education amidst the ongoing pandemic and the rise of AI chatbots. The enhanced PageRank main path algorithm, developed in this study, demonstrates its effectiveness in identifying parallel research streams developing across different fields.
