Publication lag is a determinant to journal efficiency that was not yet studied concerning Korean medical journals. To measure publication lag, we investigated the publication timestamps of 4,762 articles published by 10 Korean medical journals indexed in Scopus database, randomly selected from the KoreaMed Synapse since 2013. The total publication lag was 246.5 (Q1, Q3; 178.0, 347.0) days. The overall acceptance lag was 102.0 (65.0, 149.0) days. The overall lead lag was 123.0 (63.0, 236.0) days. The year of publication did not significantly affect the acceptance lag (P = 0.640), supposedly shortening it by about 1.4 (97.5% confidence interval [CI], −5.2 to 8.0) days/year, while the date affected the lead lag (P = 0.028), shortening it by about 12.9 (1.3 to 24.5) days/year. The Korean medical journals have reduced the total publication delay entirely by means of reducing the lead lag, not by reducing the acceptance lag.

BACKGROUND: Rapid-sequence induction is common technique to reduce anesthetic complications. Due to side effects of succinylcholine, nondepolarizing muscle relaxants have been tried. The authors tried to observe the effect of lidocaine on the onset of vecuronium. METHODS: Sixty patients were divided into lidocaine group(L) and control group(C). Anesthetic induction with 4-5 mg/kg of thiopental and 0.1 mg/kg of vecuronium was made. The L-group received 1.5 mg/kg of lidocaine 90 seconds prior to the injection of vecuronium and the C-group received normal saline with the same volume and at the same time like L-group. The ulnar nerve stimulations were applied to detect the contraction of the adductor pollicis on thumb by using Accelograph . The condition of intubation, the appearanee of arrhythmias, side effects of drugs, and the changes of mean arterial pressure and heart rate were checked and compared in peri-induction periods. RESULTS: The results are followings; (1) There were no differences in changes of MAP and HR, and the appearance of arrhythmias in 2 groups, (2) the conditions of intubation were satisfactory with same degree in 2 groups, (3) ths lidocaine pretreatment decreased significantly the onset of vecuronium (137.5+/-33.4 seconds vs. 176.4+/-62.7 seconds) comparing to the C-group and augumented the potency of vecuronium by 28% CONCLUSIONS : From the above results, the authors concluded that 1.5mg/kg of intravenous lidocaine at 90 seconds before induction can be safely used to reduce the onset time of vecuronium especially in the case of rapid endotracheal intubation. Furthermore, it is expected that lidocaine in combination with other techniques will be more effective in shortening the onset of vecuronium.

This article examined repeated measures analysis of variance (RMANOVA). Within-subjects repeated measurements are unavoidable during clinical and experimental investigation, and between- and within-subject variability should be treated separately. Only through proper use and meticulous interpretation can ethical and scientific integrity be guaranteed. The philosophical background of, and knowledge pertaining to, RMANOVA are described in the first half of this text. The sphericity assumption and associated issues are discussed in the latter half. The final section provides a summary measure analysis, which was neglected by P value-dependent interpreters.
