Fractional counting of citations can improve on ranking of multidisciplinary research units (such as universities) by normalizing the differences among fields of science in terms of differences in citation behavior. Furthermore, normalization in terms of citing papers abolishes the unsolved questions in scientometrics about the delineation of fields of science in terms of journals and normalization when comparing among different (sets of) journals. Using publication and citation data of seven Korean research universities, we demonstrate the advantages and the differences in the rankings, explain the possible statistics, and suggest ways to visualize the differences in (citing) audiences in terms of a network.

Objective Oxytocin circuits are implicated in the regulation of appetite and weight. Variants in the oxytocin receptor (OXTR) gene have been associated with bulimic behaviour. This study aimed to investigate the association between the OXTR gene and eating disorders. Method We genotyped six single nucleotide polymorphisms, rs53576, rs237879, rs2228485, rs13316193, rs2254298 and rs1042778, located within the OXTR gene in Korean patients with eating disorders using the single-base extension method. We studied a total of 262 women, including 69 patients with anorexia nervosa, 90 patients with bulimia nervosa (BN), and 103 healthy women. Results We found a positive association between the G allele of OXTR rs53576 and BN. In the BN group, the G carriers showed a high score on the behavioural inhibition system. Conclusions These findings suggest the involvement of the oxytocinergic system in the mechanism that underlies BN. Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.

Aim: Several studies have suggested that metabolic disorders are related to periodontitis. The objective of this study is to assess whether periodontitis is associated with the metabolic syndrome ( MetS) among Koreans. Material and Methods This case-control study was performed among 167 cases with MetS and 166 healthy controls from Shiwha- Banwol Environmental Health Cohort ( N = 1853). The community periodontal index ( CPI) was used to assess periodontitis ( CPI 3-4). MetS was an outcome variable and periodontitis was a main explanatory variable. Age-gender-matched conditional logistic regression models were applied. Monthly household income, smoking, drinking, physical activity and diabetes mellitus were factored as confounders. We also performed stratified analyses according to confounders. Results Those with periodontitis are more likely to be patients with MetS than those without periodontitis. The adjusted odds ratio of periodontitis for MetS was 1.76. There was no significant dose-effect response on the relationship between the number of sextants with periodontitis and MetS. Links became higher in adults aged 45-60 years and adults without diabetes mellitus. Conclusions These results suggest that periodontitis could be an independently related factor on MetS. Hence, dentists and physicians should be aware of the importance of periodontitis as a potential source of inflammatory burden. [ABSTRACT FROM AUTHOR]
