Incheon National University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Incheon National University (INU) demonstrates a robust and commendable scientific integrity profile, with an overall risk score of -0.385 that significantly outperforms many global peers. This strong foundation of ethical research practices is a critical asset in its mission to become a top 100 global university. The institution exhibits exceptional control in key areas, particularly in maintaining intellectual leadership (indicated by a minimal gap between total and led research impact) and avoiding authorship inflation. These strengths are complemented by high-impact research in strategic thematic areas, with SCImago Institutions Rankings placing INU among the national leaders in Pharmacology, Toxicology and Pharmaceutics (7th), Energy (11th), and Business, Management and Accounting (22nd). While the overall picture is one of excellence, minor vulnerabilities in institutional self-citation and redundant output warrant proactive monitoring. Addressing these incipient signals will be crucial to ensure that the university's pursuit of global recognition and "research excellence" is built upon an unshakeable foundation of transparency and integrity, fully aligning its operational practices with its ambitious strategic vision.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -0.726, a low value that nonetheless diverges slightly from the national average of -0.886. This indicates a minor but noticeable presence of risk signals related to multiple affiliations that are less common across the rest of the country. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, this slight divergence suggests that the university's collaboration patterns generate a higher rate of shared institutional credit than the national baseline. It is advisable to ensure that all affiliations are transparently and accurately reported to maintain clear institutional accountability and avoid any perception of strategic "affiliation shopping" to inflate institutional credit.

Rate of Retracted Output

With a Z-score of -0.202, the university demonstrates a more prudent profile regarding retracted publications compared to the national average of -0.049. This superior performance suggests that the institution's internal quality control and supervision mechanisms are more rigorous than the national standard. Retractions can result from honest error correction, but a lower-than-average rate points to a healthier integrity culture where potential issues are identified and resolved prior to publication. This robust pre-publication scrutiny is a significant strength, effectively mitigating the risk of systemic failures and protecting the institution's scientific reputation.

Rate of Institutional Self-Citation

The university's Z-score for institutional self-citation is -0.314, which, while low, indicates an incipient vulnerability when compared to the national average of -0.393. This suggests the institution's research ecosystem is slightly more self-referential than its peers. A certain level of self-citation is natural, reflecting the continuity of research lines. However, this slightly elevated rate warrants review to prevent the formation of 'echo chambers' where work is validated internally without sufficient external scrutiny. Proactive monitoring is recommended to ensure that the institution's academic influence is driven by global community recognition rather than being oversized by internal dynamics.

Rate of Output in Discontinued Journals

The institution exhibits a prudent profile with a Z-score of -0.313, which is notably lower than the national average of -0.217. This indicates that the university manages its publication processes with greater rigor than the national standard, effectively steering its researchers away from questionable dissemination channels. A low rate of publication in discontinued journals is a strong positive signal, demonstrating high due diligence in selecting publication venues. This practice protects the institution from the severe reputational risks associated with 'predatory' or low-quality publishing and ensures that research resources are invested in impactful and credible outlets.

Rate of Hyper-Authored Output

With a Z-score of -1.145, the institution shows a near-total absence of risk signals related to hyper-authorship, a figure that aligns with the low-risk national context (Z-score of -0.228) but demonstrates an even stronger position. This low-profile consistency indicates that the university's authorship practices are well-governed and transparent. Outside of 'Big Science' contexts where extensive author lists are normal, high rates can indicate author list inflation. The university's excellent result suggests a culture that values genuine contribution over 'honorary' authorship, thereby upholding individual accountability and the integrity of the scientific record.

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

The university's Z-score of -1.321 is exceptionally low, indicating a minimal gap between the impact of its total output and the output where it holds a leadership role. This performance is consistent with the low-risk national environment (Z-score of -0.320) but is markedly better, signaling robust internal research capacity. A wide gap can suggest that an institution's prestige is overly dependent on external partners rather than its own structural capabilities. The university's result, however, confirms that its high-impact research is driven by genuine internal intellectual leadership, a key indicator of scientific maturity and sustainability.

Rate of Hyperprolific Authors

The institution's Z-score of -0.229 reflects a prudent management of author productivity, positioning it more favorably than the national average of -0.178. This suggests that the university's processes are more rigorous in discouraging extreme publication volumes that could compromise research quality. While high productivity can be legitimate, hyperprolificacy often raises concerns about the depth of intellectual contribution and can be linked to practices like coercive authorship or data fragmentation. The university's controlled rate indicates a healthy balance between quantity and quality, prioritizing the integrity of the scientific record over sheer metrics.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the university's rate of publication in its own journals is in almost perfect synchrony with the national average of -0.252. This total alignment with a national environment of maximum scientific security demonstrates a strong commitment to external validation and global visibility. Excessive dependence on in-house journals can create conflicts of interest and academic endogamy by bypassing independent peer review. The university's very low rate confirms that its researchers consistently engage with the broader scientific community, ensuring their work is validated through standard competitive channels and avoiding the use of internal 'fast tracks'.

Rate of Redundant Output

The university's Z-score of -0.009, while low, signals an incipient vulnerability when compared to the more favorable national average of -0.379. This score suggests that the institution's research output may contain a slightly higher degree of bibliographic overlap between publications than its national peers. Massive and recurring overlap can be an indicator of 'salami slicing,' the practice of fragmenting a single study into multiple minimal units to inflate productivity. This signal warrants a review of publication practices to ensure that all published works represent significant new knowledge, thereby upholding the integrity of the scientific evidence base and avoiding an unnecessary burden on the peer-review system.
