This paper examined what factors affect the immediacy index showing the average number of times an article is cited in the year it is published. Not only Seventy-one immediacy indexes for subject field biology on JCR 2008 edition were gathered, but also many characteristics of scholarly journals that may influence the indexes directly or indirectly were aggregated. Simple correlation coefficient analysis, factor analysis, and regression analysis were performed on the paper. Therefore factors such as physical volume, availability, forthcoming issue, age and language explaining 67.64% of total variance were identified. After regression analysis using these factors as independent variables, the results were statistically significant. The results showed physical volumes, the total pages of publication, have an influence upon immediacy indexes obviously, although it is expected that journal reputations may affect immediacy indexes. Generally open access journals had high immediacy indexes. High ranked journals on immediacy index were apt to be issued frequently, uploaded very often on PMC, and published in major countries including United States and United Kingdom.

Electronic publications, including e-journals, show a rapid expansion due to its several advantages for the academic and research community. The purpose of this study is to analyze the impact of e-journals on scholarly communication. The impact factors and immediacy indices were provided via JCR social science edition have been used to conduct a series of analysis on three subject fields, economics, law and psychology. The data from the last eight years show that the impact factors of e-journals have not changed, but immediacy indices have intensely increased in recent two years. Significant increase of immediacy indices is probably due to prevalence of e-journals or electronic sources of articles. The result reveals that e-journals play an important role in speeding up the scholarly communication. It is expected that the findings of this study can contribute to more efficient management of the digital libraries.

Methods: The data for the objectives was collected major KCI index and key words of the articles in KCI web site. Results: The KJHSM has good performaces that KCI IF(2 year) is 0.98, Centrality Index(3 Year) is 1.188, Immediacy index is 0.19, and Self Citation Rate(2 Year) is 25.81. Conclusions: In order to improve the academic quantity and quality in the KSHSM, we will need the vision to corporate and participate through more good research results and performance with desirable ethic value.

This study is to analyze impact factor, self-citation, immediacy index and cited half-life through citation analysis of scholarly journals of LIS field in Korea. This study was analysed the 9,329 references cited in Korean scholarly journal of LIS field. As a result, it analyzed that the articles of Korean LIS journal among the cited references in scholarly journal of LIS field in Korea is very insignificant. In other words, the percentage of citations was observed 19.1% in Journal of Korean Library and Information Science Society (KSLIS), 20.2% in Journal of the Korean Society for Library and Information Science (KLISS), 17.0% in Journal of the Korean Society for Information Management (KOSIM), 18.8% in Korean Biblia Society for Library and Information Science (KBIBLIA). Also, the cited half-life was analysed 5.87 years in KSLIS, 5.40 years in KLISS, 4.25 years in KOSIM, 3.57 years in KBIBLIA. And Impact factor has been found to be very low compared to journals of other fields.

It is meaningful to develop the scholarly digital archives in a respect that it could preserve the research papers using digital media. The scholarly digital archives provide scientists with the information source with which scientists could actively accomplish research. This study measured based on the citation analysis to what extent PMC, which is life science scholarly digital archives, has an effect on the scholarly communication in the same subject field. The findings are as follows. First, the three citation indicators, impact factor, immediacy index, and half-life, have no remarkable difference in between pre and post-digital archives era. Second, there were more cases that the major citation indicators increased rather than ones decreased with the appearance of the scholarly digital archives, as a result of ranking the scholarly journals after classifying according to subjects.

This study started from the awareness of the issue if the citation index newly introduced to evaluate the quality of papers satisfies the proper timing matter, which is a component of performance indicators for the evaluation of government-funded R&D institutes. Accordingly, the study will propose improvement ways to shift the previous evaluation system to quality evaluation for mission-oriented R&D institutes by analysing and using the periodical characteristics such as citation half-life and immediacy index of papers. As a result, it turned out that the speed of academic change is getting faster in proportion to the dependency on the technological development but that the citation speed in the field of public technology is relatively slower and the speed of knowledge transfer in the fields related to industry is faster. In addition, the citation index among the R&D fields showed no differences, and the minimum period for citation index measurement with validity should be over 6 years. The problems of evaluation for mission-oriented R&D institutes were deducted based on the technical and statistical analysis results of the temporal characteristic of citation necessary for quality evaluation of performance among R&D fields. To solve the problems, policy alternatives for object and valid quality evaluation were proposed from the points of evaluation period and evaluation criteria.

A large and reliable citation database is necessary to identify and analyze citation behavior of Korean researchers in science and technology. Korea Institute of Science and Technology Information (KISTI) built the Korea Science Citation Database (KSCD), and have provided Korea Science Citation Index (KSCI) and Korea Journal Citation Reports (KJCR) services. In this article, citing behavior of Korean scientists on Korean journals was examined by using the KSCD that covers 459 Korean core journals. This research dealt with (1) statistical numeric information of journals in KSCD, (2) analysis of document types cited, (3) ratio of domestic to international documents cited and ratio of citing different disciplines, (4) analysis on immediacy index, peak time, and half-life of cited documents, and (5) analysis on impact of journals based on KJCR citation indicators. From this research, we could find the immediacy citation rate (average 2.36%), peak-time (average 1.7 years) and half-life (average 5.2 years) of cited journals in Korea. We also found that the average journal self-citation rate is more than 50% in every field. In sum, citing behavior of Korean scientists on Korean journals was comprehensively identified from this research.

The importance of citation measures has been increasing in the evaluation of scholarly journals and it becomes a major issue for Korean Citation Index (KCI) journals. The Journal Impact Factor (JIF), a widely used measure for academic journals, has a problematic issue that it does not include the number of citations for a paper immediately made in the year in which the cited paper was published. On the contrary, the Diachronous Impact Factor (IMP) includes the number of citations made in the published year, but IMP is a measure for papers published a few years ago, not in the last year. It does not represent the recent value of journals effectively. To overcome these problems, Total Impact Factor (TIF) and Mean Impact Factor (MIF) are proposed as new journal citation indicators. This study calculated the performance of proposed indicators experimentally on KCI data. The result shows that TIF is a promising measure for the multidimensional evaluation of humanities and social sciences journals in Korea because it has high stability by year and includes the immediate citations of the published year.
