Abstract
The adoption of IFRS increases accounting transparency and the usefulness of accounting information. Thus, we expect that opportunistic earnings management can be reduced by adopting IFRS. However, IFRS is a principle?based standard with which assets and liabilities are recorded with their fair value, and consolidated financial statements are a primary report. The adoption of IFRS can increase the management"s discretion on earnings management. Thus, opportunistic earnings management can be increased after the adoption of IFRS. Therefore, the effects of IFRS adoption on earnings is a matter of empirical question. On the other hand, the adoption of IFRS increases the importance of audit quality and the abnormal audit hour is a proxy of audit quality. Thus, the abnormal audit hour can have an additional influence when the adoption of IFRS affects opportunistic earnings management. In this study, we selected total 3,935 firm?year from 2009 to 2012 as the samples, targeting non?financial companies of December 31 fiscal year?end listed on the KOSPI and KOSDAQ of the 2012 year?end and have done an empirical analysis. The main empirical results of this study are as follows. First, after the adoption of IFRS, discretionary accruals and real earnings management were significantly decreased. This means that the adoption of IFRS increases accounting transparency. Second, while the adoption of IFRS reduced earnings management, abnormal audit hour did not have additional influence on the reduction of earnings management. The results of this study imply that the adoption of IFRS decreases opportunistic earnings management, but the role of abnormal audit hour as an audit quality is not changed by the adoption of IFRS.

Abstract
This research studies an alternative plan to improve the material flow between two production lines through a case of R motors. That is, this paper investigates the effectiveness of changing manned tow trucks into an unmanned logistics system based on AGVs (Automated Guided Vehicles) to move door, hood, and trunk assemblies. Witness is adopted for this simulation study. The experiment first determines the optimal number of AGVs. In addition, the use of a single line is tested for AGVs. Finally, this research shows that the investment on the unmanned logistics system is effective.

Abstract
The present study tried to verify if the endowment effect would be enlarged under the situation of self identity?threatening. It was investigated if the endowment effect for Korean products would be intensified under the situation of Korean ID?threatening and if the endowment effect for foreign products would be intensified under the global ID? threatening situation. It was also examined if, under the situation of Korean ID?threatening, the endowment effect for Korean products could be intensified when Korean ID would be primed, whereas it was explored if, under the global ID?threatening situation, the endowment effect for foreign products could be intensified when global ID would be primed. As objects of experiment, Korean? and foreign?made ballpoint pens were sampled out and experimentation was designed in 2 (Korean and foreign products) × 3 (basic, threatening and added priming). ANOVA was conducted to find the results as follows: First, an ID?threatening situation exercised positive impact upon the endowment effect for ID?related products owned. Second, few significant increase was confirmed for the endowment effect of the products owned under the both domestic as well as global ID?threatening situations in which both domestic as well as global ID"s were primed, respectively. From the Additional analysis, it was made known that no significant difference was disclosed in both intended selling and buying prices between Korean basic group and Korean ID?threatening group. Such results definitely implied that the intended selling and buying prices of Korean?made products used to be fixed differently depending on individuals under the Korean ID?threatening situation so that it seemed impossible to explain the increase of the endowment effect for Korean?made products just by a single straight change of either intended selling price or buying price. Another ANOVA showed that there was no signifiant difference in the intended selling price for the foreign? made products owned between the basic and global ID?threatening groups, but on the other hand, there was significant difference in the intended buying price between both groups, suggesting that the endowment effect of the foreign?made products was caused by the difference in the intended buying price as the global ID was threatened.

Abstract
The purpose of this study was to investigate empirically the impact of implementation strategies of wage peak system on its effectiveness and the moderating role of employee need strength in the relationship between implementation strategies and effectiveness of wage peak system. The results showed that, first, perceived necessity for wage peak system had a significant relationship with employee acceptance of and satisfaction with wage peak system. Second, there was a positive relationship between implementation strategies( understanding for the implementing model , clarified goal, consensus building) and effectiveness of a system like employee acceptance and satisfaction. Third, a moderating role of employee growth need strength was identified in the relationship between implementation strategies and effectiveness of wage peak system. Finally, some practical recommendations for implementing wage peak system more effectively are suggested.
