  • Recently, the valuation of patented technology has been greatly emphasized, and patent citation has been accepted as a very useful index of this technology. In this study, we performed correlation analyses between the patent citation counts and 17 explanatory variables of morphological, technological, and conceptual factors with a test dataset of U.S. patents in five subject fields. Seven variables having 5% or more standardized variances($r^2$) with patent citation counts were identified; number of pages, number of claims, reference-average-citation rate, patent increase/decrease rate, strength of bibliographic coupling, co-citation counts and document similarity. The result of the ANOVA test shows that the mean values of these variables vary among most subject fields.

  • Recently, the valuation of research papers has been greatly emphasized, and their citation has been accepted as a very useful indicator. In this study, we performed correlation analyses between the paper citation counts and 11 explanatory variables of morphological and conceptual factors with a test dataset of the papers of 11 journals in library and information science. The analysis results of the correlations show that only the document similarity has 5% or more standardized variances(r2) with paper citation counts and the document similarity with citation counts get higher as the variable value increases.

  • The valuation of patented technology has been recently emphasized, and the patent citation is known as an important factor. This study performed a generalized linear model to find variables that effect the patent citation. We classified 13 variables as morphological, technological and conceptual factors and used them to find out effective variables in 14 medical devices classification. Through the empirical study, we found seven effective variables (assignee nationality, assignee character, the number of inventors, the number of application countries, the number of IPC, the number of references, the strength of bibliographic coupling). In order to apply to Korean industry, this study has significance that provides basic research to citation analysis model.

  • This study describes the meaning of and the formula for Kor-$h_T$, which is a modified index built on the tapered h-index by applying 'the ranking according to the number of citations of journals'. This study evaluated the de-duplication rate of index values of Kor-$h_T$ and analyzed the change in the correlation between the index values and evaluation elements using the Korea Citation Index data from 2008 to 2010. Kor-$h_T$ is compared with h-index, tapered h-index, and IF. As a result, Kor-$h_T$ appeared to be superior to other indexes on de-duplication rate. It is also shown that there is a very strong positive correlation between the evaluation elements, the number of citations and the number of articles of journals, and the index values of Kor-$h_T$.

  • The purpose of this study is to develop a prediction model of patent citation counts based on major factors which affect patent citation. To this end, we performed multiple regression analysis between the patent citation counts and five explanatory variables such as the number of pages, the number of claims, the reference-average-citation rate, the strength of bibliographic coupling, and the document similarity proved as having 5% or more standardized variances($r^2$) with patent citation counts, with a test dataset of U.S. patents in five subject fields. As a result, our prediction models showed 58.3% to 89.6% predictability depending on subject fields and revealed the document similarity has the highest impact on citation counts among the five predictive variables in all the subject fields. The result of comparison between the predicted citation counts and the actual ones confirmed the usefulness of the citation prediction models built for each subject field.

  • 이 연구는 한국 학계가 그간 많은 성장을 일구어 왔음에도 질적 수준에 대해서 지속적인 비판을 받고 있는 현 상황에 의문을 갖고 연구를 시작하였다. 최근 연구의 질적 수준 제고를 위해 연구개발 성과평가 제도가 전면적인 변화를 겪고 있음에도 정작 한국 학술연구의 질적 수준 문제가 어떠한 양상으로 나타나고 있는지 과학적인 증거를 제시하고자 하는 노력은 지금까지 매우 미흡했다. 이에 이 연구에서는 한국 연구의 양적 성장과 질적 성장 간의 괴리가 어떠한 양상으로 나타나는지 가시적인 일면을 제시하기 위하여 한국 연구자가 포함된 모든 SCI 논문을 수집하고 이를 대학, 출연연, 기업, 해외기관, 기타 소속 저자로 구분하여 양적 추세와 피인용횟수 추세를 비교하고자 하였다. 분석결과 해외기관 소속 저자와 국내기관 소속 저자 간에 유의미한 수준의 피인용횟수 격차가 나타나고 있으며, 이러한 격차는 시간의 흐름에 따라 해소되지 않고 있는 것을 확인하였다. 또한 분야별로 격차가 다르게 나타나 생화학 분자생물학이나 신경과학 신경학 등의 분야에서 피인용횟수의 격차가 보다 높게 나타나고 있었다. 이러한 결과는 최근 한국 공공연구 영역에서 전면적으로 일어나고 있는 질적 평가체제로의 전환 움직임에 대해서 그 세부적인 설계와 차등 요건의 적절성에 대해 다시 한 번 생각해볼 수 있는 계기를 제공한다.

  • The purpose of this study is to verify the correlation between the appearance frequency of author keyword and the number of citation in journal articles. In this study, we were trying to develop a methodology that can select the term having semantic relation with other terms and higher utilization to build a structured scientific glossary. In order to achieve this purpose, we analyzed the number of citation and the author keyword of the humanities and social science journal articles of the Korea Citation Index (KCI) from 2007 to 2011. This study found a correlation between appearance frequency of author keyword and the number of citation of the journal articles, with higher appearance frequency of author keyword of the journal articles being more cited.

  • Purpose: No attempt has been made to identify the relationship between the study characteristics and citation rates of articles published in the Journal of the Korean Orthopaedic Association (JKOA). This study classified the study characteristics of articles in the JKOA and analyzed the relationship between the study characteristics and citation rates. Materials and Methods: A cohort study was conducted on all articles published from February 2001 to December 2015. Three independent reviewers classified the articles according to the article type, material, time of the study, design, clinical categories, number of authors, and number of cases. The citation numbers of each article by other journals were taken in January 2020. Univariate analyses were conducted to assess the effect of each characteristic, and multivariate linear regression analysis was performed to analyze the overall relationship between the characteristics and the citation rates. Results: A total of 1,640 articles were published from 2001 to 2015, and 724 articles were cited more than once. The articles published in 2009 had the highest average number of citations. Original articles had the highest citation rates, followed in descending order by surgical techniques and reviews, instructional course lectures, and case reports (p<0.001). Among the case reports, articles dealing with general trauma scored significantly higher average citations (mean=1.5, p=0.006). Among the original articles, articles on general orthopedics had the highest citation rates, followed in order by clinical articles and experimental articles. Among the clinical articles, epidemiologic studies (mean=5.0, p<0.001) and studies on the spine (mean=1.7, p<0.001) recorded significantly higher citation rates than the others. Conclusion: Of all the articles published in the JKOA from 2001 to 2015, articles dealing with general trauma had the highest citation rates among case reports. Among the original articles, epidemiologic studies and studies concerning the spine were cited significantly more than others.

  • The Korea Port Economics Association was established in 1985 and has been operated for academic research on port economics and research on port logistics. Marking the 35th anniversary of its establishment, it is necessary to establish a new development strategy for academic societies and academic journals. This study analyzed the current status of publication of the Journal of Korea Port Economic Association, from the first issue of 2017 to the December issue of 2019, the utilization and systematic nature of this journal, and the efforts implemented to improve the quality of the journal. The recognition, utilization, and subject inconsistencies were analyzed to determine the academic value of the journal. The findings suggested the journal's academic excellence, as evidenced by its highest ranking by Journal Impact Factor among agro-oceanography journals (among 77 journals) and marine transport journals (among four journals). Further, the direction of development for this academic journal was presented with reference to research characteristics and specialization efforts.

  • This study pointed the factors affecting the number of articles and citations in material science which is the most active publishing disciplinary in South Korea. This was conducted by gathering the information on SCIE which had been published by 449 Korean professors in material science from 2006 to 2010. One of the results was that the professors who had published more papers received more citations than those who did not, reconfirming former studies abroad. It was observed that the factors majors impacting on the number of papers may be their academic positions, educational backgrounds (particularly undergraduates), and places of work. The number of citations was affected by the authors' undergraduate and their locations of the work. This study suggested a need for more supports on basic researches by universities and funding bodies and an amendment of performance measures to include the number of citations.
