The Relationship Between Chaebol And Firm Value Using Bayesian Network

The purpose of this study is to analyze the effects of being a chaebol company, the biggest company characteristic variable, on firm value. It tries to overcome the limitation of multiple regression analysis mostly used in preceding research. That is, as multiple regression analysis assumes uniform linearity between dependent and independent variables, it could not reflect the diverse types of the real world. Thus, based on being a chaebol company and financial information, company characteristic variables influencing firm value, this study derives causal relationships existing between them. The results could help managers and various accounting information users in their decision-making by providing them with information of what company characteristics would directly or indirectly influence firm value. To this end, this study utilizes Bayesian Network and attempts Markov Blanket. In the end, all the analysis methods used in this study not only provides significant results, but also raises its practical value by offering information of diverse situations that could occur in the real world

Is Foreign Direct Investment Effective From The Perspective Of Tax Avoidance? An Analysis Of Tax Avoidance Through The International Transfer Pricing Behaviors Of Korean Corporations

This study examines whether multinational companies carry out tax avoidance through subsidiaries. An empirical analysis was conducted of 4,585 Korean firms from 2001 to 2010 by company and year. The results are as follows. First, MNCs that have become more internationally diversified through the establishment of overseas subsidiaries generally show a higher tendency to avoid tax. Thus, the analysis results show a positive correlation between globally diversified MNCs and corporate tax avoidance. This correlation is established due to the firms' active use of tax strategies (investment tax credits, tax cuts) applicable to the various countries in which they have expanded their businesses. Second, the analysis results showed that these firms actively avoided tax with overseas transfer pricing behaviors when compared to companies without overseas subsidiaries. Thus, the adjustment of sales prices and purchase value through actual transactions increased the propensity of the parent company to avoid tax.

Percutaneous Cardiopulmonary Support in Refractory No-Reflow with Cardiogenic Shock after Coronary Stenting in Acute Myocardial Infarction

Coronary no-reflow is defined as inadequate myocardial perfusion of a given coronary segment without angiographic evidence of mechanical vessel obstruction. No-reflow is visualized angiographically as a reduction in thrombolysis in myocardial infarction (TIMI) flow grade and is typically accompanied by chest pain, electrocardiographic changes with ST-segment shift and possible hemodynamic compromise. No-reflow during primary percutaneous coronary intervention (PCI) results in increasing mortality and morbidity. Therefore, treatment of noreflow is associated with improved clinical outcomes. Generally, the treatment of no-reflow is based on pharmacotherapy. In this case, despite maximal pharmacotherapy and intraaortic balloon pump (IABP), refractory no-reflow accompanied with cardiogenic shock was successfully treated with percutaneous cardiopulmonary support (PCPS)

The Initial Extent of Malapposition in ST-Elevation Myocardial Infarction Treated with Drug-Eluting Stent: The Usefulness of Optical Coherence Tomography

PURPOSE: The aim of this study is to identify the extent of initial malapposition using optical coherence tomography (OCT) in ST-elevation myocardial infarctions (STEMI) treated with different types of drug-eluting stents (DES). MATERIALS AND METHODS: Twenty four STEMI patients that underwent primary percutaneous coronary intervention (PCI) were enrolled. The OCT and intravascular ultrasound (IVUS) were performed within 72 hours after the primary PCI. Distances between the endo-luminal surface of the strut reflection and the vessel wall and the extent of malapposition were measured and analyzed. RESULTS: Sirolimus-eluting stents (SES), paclitaxel-eluting stents (PES) and zotarolimus-eluting stents (ZES) were deployed in 7 patients (29%), 7 patients (29%) and 10 patients (42%). In total, 4951 struts in 620 mm single-stent segments were analyzed (1463 struts in SES, 1522 in PES, and 1966 in ZES). In strut analysis by OCT, the incidence of malapposition was 17 % (860/4951) and in stent analysis by IVUS, malapposition rate was 21% (5/24). The malapposition rate of strut level using OCT in 5 patients who had malapposition in IVUS was significantly higher than the 19 of those who had not (32 +/- 5% vs. 12 +/- 6%, p = 0.001). In addition, the frequency of malapposition was also significantly different (28% in SES, 11% in PES, 10% in ZES, p = 0.001). The use of SES was an independent predictor of malapposed struts. CONCLUSION: The incidence of malapposition using OCT was quite prevalent in STEMI after primary PCI with DES implantation and SES has especially higher rates of malapposition compared to other DESs.ope

The microwave spectrum and structure of the methanol⋅SO2 complex

The rotational spectra of nine isotopomers of the methanol⋅sulfur dioxide van der Waals complex were observed with a pulsed molecular beam Fourier transform microwave spectrometer. Each rotational transition is split into an A‐state (m=0) and an E‐state (m=±1) transition due to methyl top internal rotation effects. The A and E transitions show an additional inversion splitting ranging from a MHz to a few tens of MHz in seven of the isotopomers. The inversion splitting is absent in the two S16O18O isotopomers. The center frequencies of the inversion doublets were used in a simultaneous fit of both the A‐ and E‐state transitions, producing rotational constants which allowed a complete determination of the structure of the complex. Analysis of the moments of inertia indicate that the complex has a stacked structure. The center of mass distance between the two monomers is 3.08(5) Å. The effective torsional barrier height is V3=128.6(1) cm−1 based on the assumption that the methyl group rotates against a heavy frame. The dipole moment is μT=1.94(3) D. The inversion motion is discussed based on effects on the splitting associated with isotopic substitution and the transition dipole direction. © 1995 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71010/2/JCPSA6-103-15-6440-1.pd

A Comparative Study of Governance in State Management: Focusing on the Roh Moo-hyun Government and the Lee Myung-bak Government

This study aims to explore development discourses of the Roh Moo-hyun and Lee Myung-bak governments and evaluate their governance in achieving their respective visions of development. The two governments advocate sustainable development and green growth, respectively, as their national development paradigms, and strategies, laws, and organizations were developed to realize their goals. This research analysis reveals that the Roh administration perceived and reflected the concept and the importance of governance into its own policy framework while the Lee administration has not. The Roh administration perceived civil society as the subject of governance and policy process whereas the Lee administration perceives it as the object. In conclusion, the Roh administration can summarily be described as non-authoritarian with civil societycentered governance that pursues sustainable development, while the Lee administration is authoritarian with token state-centered governance that pursues green growth. This difference results from the difference between the nature of development discourse, principles of government management, perception of governance, leadership style and values, and the support basis of each government
