Objectives : We investigated the effects of sleep apnea syndrome (SAS) on cognitive functions in patients with REM sleep behavior disorder (RBD). We also studied correlations between sleep variables related with SAS and parameters of cognitive function tests. Methods : Twenty two RBD patients with SAS and 20 RBD patients without SAS participated in the study. The diagnoses of RBD and SAS were confirmed on polysomnography. All the participants performed neuropsychological tests by the Korean version of the Consortium to Establish a Registry for Alzheimer’s disease (CERAD-K) Assessment Packet. Results : There were no differences between two groups in age and sex, education, body mass index, and results of the Beck depression inventory (BDI) and the Epworth sleepiness scale (ESS). No difference was found in any of parameters of the CERAD-K between two groups. The cognitive functions were not correlated with BDI, ESS, or variables related with SAS. Conclusion : SAS had no influence on cognitive functions of RBD patients. The result could be explained by negligible effects of SAS on cognitive functions among aged population and no difference in daytime sleepiness between the RBD patients with and without SAS.

Economic debate has continued over whether an acquisition, even without control or influence, may still have anticompetitive effects under certain circumstances. The contention is that an acquiring company, even with a non-controlling minority interest, may unilaterally increase price or decrease production (unilateral effect), or cause the acquiring company and the acquired company to mutually cooperate with each other (coordinated effect). Based on these notions of “unilateral effect” and “coordinated effect,” Courts and antitrust enforcement authorities in United States and Europe have prohibited certain minority acquisitions and acknowledged their anticompetitive effects. Furthermore, in 2010, the U.S. Department of Justice and the Federal Trade Commission released the Horizontal Merger Guideline, which addresses minority acquisitions and outlines a detailed framework for determining whether a minority acquisition is anticompetitive. Likewise in July 2014, the European Commission released White Paper, “Towards More Effective EU Merger Control,” which considers the introduction of a regulatory system of notice filing for certain minority acquisitions. In 2011, influenced by the 2010 Horizontal Merger Guidelines, the Korea Fair Trade Commission (“KFTC”) also acknowledged the possibility of evaluating minority acquisitions and pushed to amend the Guideline for M&A Review in order to provide a detailed framework for the evaluation of minority acquisitions. However, the KFTC withdrew the amendment because in its view, the amendment would burden businesses and conflict with the existing regulatory framework. Nonetheless, in order to guard against potential risks, it is only rational to reconsider the 2014 amendment to the Guideline for M&A Review. In fact, deeming certain minority acquisitions as anticompetitive does not conflict with the existing antitrust regulations, and evaluating minority acquisitions for anticompetitive effects does not burden businesses because actual instances of antitrust threat posed by minority acquisitions are few and far between.
