The globalization of financial markets has broadened investment opportunities. International investors' investment portfolios consist of financial instruments from various countries; consequently, the risks associated with economic dependence among countries should be carefully considered. Step-down equity-linked securities (ELS) are a structured financial product that have recently become popular among Korean investors. Payoffs are based on two or three stock indices from different regions; therefore, dependence between the indices should be reflected in the risk analysis. In this study, we consider a regime-switching copula model to describe the joint behavior of two stock indices- the Eurostoxx50 and the Hang Seng China Enterprises Index (HSCEI). These indices are commonly used as underlying assets of step-down ELS. Using historical data, we analyze the risk associated with step-down ELS through the probabilities of early redemption. A regime-switching copula model can accommodate complicated dependence. Thus, it should be considered in the risk analysis of step-down ELS.

The purpose of this paper is to present a neural network model based on change-point detection for the prediction of the U.S. Treasury Securities. Interest rates have been studied by a number of researchers since they strongly affect other economic and financial parameters. Contrary to other chaotic financial data, the movement of interest rates has a series of change points due to the monetary policy of the U.S. government. The basic concept of this proposed model is to obtain intervals divided by change points, to identify them as change-point groups, and to use them in interest rates forecasting. The proposed model consists of three stages. The first stage is to detect successive change points in the interest rates dataset. The second stage is to forecast the change-point group with the backpropagation neural network (BPN). The final stage is to forecast the output with BPN. This study then examines the predictability of the integrated neural network model for interest rates forecasting using change-point detection.

The purpose of the study is to make a proposal of how to improve the separate account in Korean life insurance accounting and regulations. A separate account is required to improve the transparency of accounting and fairness of dividing the profit between company and lift insurance contractors. A separate account may be the first step to solve this conflict by clearing the profit sharing of shareholder's and contractor's of the insurance with dividend. The separate account should be designed to reflect the real economic consequences of insurance company and consider the real outcome of the performance-based insurance commodities. The separate account should contain the rules of IASs and KASs. If a separate account is successfully settled down, the portions of contractor's dividend and the dispute about initial public offering of insurance companies can be solved gradually.

Enacted for enhancing the competitiveness of the Korean capital market and financial industry, Capital Market Consolidation Act (CMCA) was intended to induce considerable changes such as adopting the concept of financial investment products, regulating financial investment functionally, extending financial investors' business areas and intensifying protection for investors. Employing DEA (Data Envelopment Analysis), this study measures and compares the efficiencies of domestic financial companies between the before and after the enactment of the Consolidation Act. We categorize the financial companies into 4 groups (banks, life insurance companies, property and casualty insurance companies and securities companies) depending on their business types, and evaluate how much and in which direction the Consolidation Act affects the efficiency of each group respectively. The study shows that there is no significant difference between the average efficiency of banks and that of property and casualty insurance companies due to the trade-off between opportunities and threats of the Act. To the contrary, it shows that the respective average efficiencies of life insurance companies and securities companies moved in the opposite directions to a considerable extent. Through empirical tests, we demonstrate the effect of the Act on the efficiency of Korean financial companies, and suggest the countermeasures for each financial group against the Act.

Recently, enterprises have reinforced security control in order to prevent infringement of personal information and abuse of customer information by insiders. However, the reinforcement of security control by enterprises makes it difficult for internal users to perform business by using a business information system. There is, therefore, a need for research on various fields, which makes it possible to establish an appropriate security control policy while minimizing an impact on business. The present research verifies and analyzes an impact on difficulty in business of internal users using customer information, which is caused by security control performed by display restriction on customer information identifiers. The present research is intended to academically develop a technique for statistically analyzing an impact degree and a causal relationship between security control and an impact on business, which is a dichotomous variable, and to practically contribute to the establishment of an efficient security policy in consideration of an impact on business when an enterprise applies security control. A research target was internal business information systems of domestic securities enterprises, data was collected by questionnaire, and verification/analysis was performed by logistic regression analysis.

The aims of this study are to analyze the current states and problems of development finance in the regional development projects, and to examine new sources and techniques of development finance for activating regional development projects. Analyzing the current states of development finance in regional development project, the problems such as the poorness of development function, the low accessibility to formal financial market, especially capital market, and the dominant use of corporate financing can be seen. In these context, four alternatives are proposed in order to activate development finance. First alternative is to use the funds which invest the equity of real estate, such as REITs. The second is to activate project financing. The third is to use asset backed securities. The forth is using mezzanine capitals as the means of protecting investors.

This paper evaluates the role of fund distributors and the appropriateness of sales fees in funds by the empirical analysis of Korean equity funds. The empirical results are summarized as follows. First, this paper shows that the funds with higher sales fees do not have better performance. Rather, the higher sales fees cause the returns of funds to decrease in Korean equity funds. Second, it is not confirmed that both banks and securities firms, as fund distributors, contribute to the better performance of funds. Especially, the banks gave more negative influence on the performance of funds by imposing higher sales fees in funds than the securities firms. The empirical results suggest that the sales fees of funds are unduly imposed in comparison to the function of fund distributors and therefore, the structure of fund fees should be improved for the benefit of fund investors.

This paper examined closely on the application of the private securities to the measures for countering terrorism. It is related to the fact that the role of human information comes into the picture nowadays. On closer examination of the application of the private securities to the national facilities, transportation, and multi-use facilities, it was found that having consistent commissioned education through the private-public cooperation and enacting legislation for allowing armed guard to board ships, making private security guards to use sniffer dogs, placing private security guards in each subway station is required, and the active publicity campaign of the government concerned needs to take place for directing and setting up the system for supervising managers of the authorities and changing the way they think of countering terrorism.
