Korea Maritime University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Korea Maritime University demonstrates an outstanding scientific integrity profile, with an overall risk score of -0.636 that indicates robust and responsible research practices. The institution's primary strengths lie in its exceptionally low rates of hyperprolific authorship, multiple affiliations, and hyper-authored output, alongside a minimal gap in impact leadership, showcasing a culture of quality, transparency, and scientific autonomy. Minor vulnerabilities are noted in the areas of institutional self-citation and redundant output, which, while still classified as low-risk, present slight deviations from the national average and merit proactive monitoring. According to SCImago Institutions Rankings data, the university's strongest thematic areas nationally include Economics, Econometrics and Finance (ranked 31st), Earth and Planetary Sciences (34th), and both Mathematics and Social Sciences (49th). Although the institution's specific mission was not available for this analysis, its exemplary integrity performance strongly aligns with the universal academic mandate for excellence, ethical conduct, and social responsibility. The identified low-risk signals do not compromise this alignment but rather offer an opportunity to refine internal policies further. It is recommended that the university leverage this strong integrity profile as a strategic asset to enhance its reputation and attract premier talent, while implementing light-touch monitoring on the few indicators showing incipient vulnerability to ensure continued leadership in research quality.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -1.336, significantly lower than the national average of -0.886. This result signals a state of total operational silence regarding this risk indicator, with an absence of problematic signals that is even more pronounced than the already low national standard. While multiple affiliations can be legitimate, the university's exceptionally low rate demonstrates a clear and unambiguous approach to institutional credit, effectively eliminating any suspicion of strategic "affiliation shopping" and reinforcing a culture of transparent collaboration.

Rate of Retracted Output

With a Z-score of -0.587, the institution shows a near-total absence of risk signals, in contrast to the country's low-risk score of -0.049. This low-profile consistency suggests that the university's internal quality control and supervision mechanisms are highly effective. Unlike the national environment where retractions occur at a low but measurable rate, the institution's performance indicates that potential errors or methodological issues are successfully identified and corrected prior to publication, safeguarding its scientific record and demonstrating a robust culture of integrity.

Rate of Institutional Self-Citation

The institution's Z-score of -0.023 is numerically higher than the national average of -0.393, indicating an incipient vulnerability. Although both scores fall within the low-risk category, the university shows a slightly greater tendency toward self-citation than its national peers. A certain level of self-citation is natural to reflect ongoing research lines; however, this minor elevation warrants observation. It is a subtle signal that could, if unmonitored, grow into a scientific "echo chamber," where the institution's impact is partially inflated by internal dynamics rather than validated by the broader external academic community.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.169 is statistically aligned with the national average of -0.217. This correspondence reflects a state of normality, where the risk level is as expected for the national context. It indicates that the university's researchers are exercising appropriate due diligence in selecting publication venues, showing no significant exposure to the reputational damage associated with channeling work through "predatory" or low-quality journals that fail to meet international standards.

Rate of Hyper-Authored Output

The institution's Z-score of -1.226 is exceptionally low, contrasting with the national average of -0.228. This demonstrates a consistent and low-risk profile, suggesting that the university's authorship practices are well-governed and transparent. While extensive author lists are normal in "Big Science," the institution's very low rate outside these contexts indicates a healthy culture that avoids the inflation of author lists with "honorary" or political inclusions, thereby preserving individual accountability and the integrity of its research contributions.

Gap between Impact of total output and the impact of output with leadership

With a Z-score of -1.018, the institution exhibits a very low-risk profile that is significantly stronger than the national average of -0.320. This result indicates that the university's scientific prestige is structurally sound and built on genuine internal capacity. The minimal gap between its overall impact and the impact of research where it holds intellectual leadership is a powerful sign of scientific autonomy and sustainability, confirming that its excellence metrics are not dependent on an exogenous or strategic positioning in collaborations led by others.

Rate of Hyperprolific Authors

The institution's Z-score of -1.413 is exceptionally low, far below the national average of -0.178. This low-profile consistency points to a research environment that effectively balances productivity with quality. The near absence of authors with extreme publication volumes suggests that the university's culture discourages practices such as coercive authorship or "salami slicing," which prioritize metric inflation over the integrity of the scientific record and meaningful intellectual contribution.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 shows a strong integrity synchrony with the national average of -0.252. This total alignment reflects a shared commitment to maximum scientific security within the country. By avoiding over-reliance on its own journals, the university demonstrates a preference for independent external peer review, thus mitigating the risks of academic endogamy and potential conflicts of interest. This practice enhances the global visibility and competitive validation of its research output.

Rate of Redundant Output

The institution's Z-score of -0.215, while in the low-risk category, is higher than the national average of -0.379, signaling an incipient vulnerability. This suggests that the university exhibits a slightly greater tendency toward bibliographic overlap than its peers, which warrants review before it escalates. A higher rate of redundant output can be an early indicator of "salami slicing"—the practice of fragmenting a single study into multiple publications to inflate productivity—which can distort the scientific evidence base and prioritize volume over significant new knowledge.
