This study examines the dynamic hedging performances of the Black-Scholes model and Heston model when stock prices drift with stochastic volatilities. Using Monte Carlo simulations, stock prices consistent with Heston's(1993) stochastic volatility option pricing model are generated. In this circumstance, option traders are assumed to use the Black- Scholes model and Heston model to implement dynamic hedging strategies for the options written. The results of simulation indicate that the hedging performance of a mis-specified Black-Scholes model is almost as good as that of a fully specified Heston model. The implication of these results is that the efficacy of the dynamic hedging performances on evaluating the specifications of alternative option models can be limited.

We analyze the information asymmetry in the capital market by examining the long-term performance by the insider's trading behavior in the companies that made investment announcements for the construction of the new office building. The results are summarized as follows. On average, the long-term abnormal returns on share prices of sample firms represent a significant positive value. The regression analysis confirmed that there is a statistically significant positive correlation between the factor of the change in equity of large shareholders and the long-term performance. On the other hand, negative correlation was observed between change in equity of small individual investors and long-term performance. These results mean that an insider can determine the authenticity of a manager's private intention. In other words, it supports that the insider is in a position of information superiority. In addition, it is expected to provide practical usefulness to investors in that the change in equity can be used as a predictor of long-term performance.

Local government has constructed GIS DB for efficient business achievement and effective management of complex city facilities and has been developing and utilizing application systems, such as Underground Facility Management System Road Management System and so on. However, Facility Management System is providing functions for business, but not for GIS DB's maintenance. City facilities GIS DB managed by GIS technical expert collects basic figure and attribute information through survey and field investigation and is constructed via complex process, such as structurize editing etc. So it has been concerned that the update and confidence of CIS DB can be lower if a business man who does not have enough experiences about Facility Management System operates it by himself. Therefore, functions that enable business users to operate Facility Management System easily should be provided.
