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.

As for Korea, China is very important because of an advantageous geological accessibility and high economic dependency. Therefore, the Korean government announced its plan to establish 5billion dollars' investment from Greater China (including Hong Kong and Singapore) and the government has put much effort into accommodating more Chinese investment by diversifying investment channels from Greater China. Under this major Chinese investment boom, it is crucial to conduct in-depth research on accommodation of Chinese investment and create a plan to establish Chinese capital investment that will benefit both the investing country and the countries receiving the investment. Hence, the present study analyzed current trends in Chinese investment for the Korean market, focusing on the stimulation methodology for establishing greater investment from China. To this end, this paper examined various investment characteristics of Chinese investors for the Korean market by researching investment development levels on different time lines and analyzing Chinese investment in Korea for a variety of industries. Through the research, the following study derived a more effective strategy to accommodate greater Chinese capital investment. There has been a worldwide increase in the number of letter of credit cases involving fraud recently. It may happen that the documents which are tendered to the banks under a documentary credit are forged, altered or fraudulent. Banks assume no liability or responsibility for the form, sufficiency, accuracy, genuineness or falsification of any documents.

We have developed new display techniques that allow presentation of nearly correct focus cues. Using these techniques, we find that stereo vision is faster and more accurate, and that viewers experience less discomfort, when focus cues are consistent with simulated depth.

This paper examines the hypothesis that states consolidation and concentration within Korean banking industry have impaired competition and escalated market power of banks. Competition is measured using Bresnahan-Lau method, which estimates a structural model consisting of a demand function and a supply function of banking services, based on aggregate monthly data of January 1996 to December 2002. Estimations indicate that pricing behavior of Korean banks during the period is consistent with perfect competition, and they behave more competitively even after the increase in concentration ratio. The results imply that, contrary to the concerns over the potential for monopoly power, bank competition may not be damaged by the consolidation.

This paper proposes a robust speech recognition algorithm based on the wavelet filter banks. Since the proposed algorithm adopts a multiple band decision-making scheme, it performs robustness for noise as the presence of noisy severely degrades the performance of speech recognition system. For evaluating the performance of the proposed scheme, we compared it with the conventional speech recognizer based on the VQ for the 10-isolated korean digits with car noise. Here, the proposed method showed more 9~27% improvement of the recognition rate than the conventional VQ algorithm for the various car noisy environments.

This paper proposes the allocation method for capacitor-reactor banks in a distribution system with dispersed generators to reduce the installation costs, the maintenance costs and minimize the loss of electrical energy. The expected lifetime and maintenance period of devices with moving parts depends on the total number of operations, which affects the replacement and maintenance period for aging equipment under a limited budget. In this paper, the expected device lifetimes and the maintenance period are included in the formulation, and the optimal operation status of the devices is determined using a genetic algorithm. The optimal numbers and locations for capacitor-reactor banks are determined based on the optimal operation status. Simulation results in a 69-bus distribution system with the dispersed generator show that the proposed technique performs better than conventional methods.

Most of banks in Korea provide smartphone banking services. To use the banking service, public key certificates with private keys, which are stored in personal computers, should be installed in smartphones. Many banks provides intermediate servers that relay certificates to smartphones over the Internet, because the transferring certificates via USB cable is inconvenient. In this paper, we analyze the certificate transfer protocol between personal computer and smartphone, and consider a possible attack based on the results of the analysis. We were successfully able to extract a public key certificate and password-protected private key from encrypted data packets. In addition, we discuss several solutions to transfer public key certificates from personal computers to smartphones safely.

Transient in an electric distribution system are mainly generated by switching. This paper presents analysis of switching surge and means of limiting the voltage magnification transient for high voltage power systems by using the EDSA's EMTAP software package. One means of limiting the voltage magnification transient is to convert the end-user power factor contraction capacitor banks to harmonics filters. An inductance in series with the capacitor bank was used to decrease the transient voltage at the customer bus to acceptable levels. And also simulation results used the EDSA harmonics analysis program show the effect of harmonics reduction.

High temperature fuel cell system, such as molten carbonate fuel cells(MCFC) and solid oxide fuel cells(SOFC), are capable of operating at MW rated power output. The power output change of high temperature fuel cell imposes the thermal and mechanical stresses on the fuel cell stack. To minimize the thermal-mechanical stresses on the stack and increase the systems reliability, we should divide the power plant configuration to several banks. However, the improvement of reliability in fuel cell power plant system causes an increase of the investment cost, for example, replacement costs, labor costs, and so on. For this reason - the balance between investment and reliability improvement - many studies about the appropriate level of investment have been conducted. In this paper, we evaluate the cost for operation and installation, the benefit for electric energy and thermal energy sales, and the system reliability for several cases : these cases relate with the bank configuration.

A two-dimensional numerical model was applied to investigate the sediment transport and sand bank formation in a macrotidal sea, the Kyunggi and Asan Bays. The tidal residual currents show quite complex pattern including counter-rotating eddies off the northwestern corner of the Dugjeok Island that reflect the promontory effect. Complex residual eddies are also present off the coast of the Taeanbando and in the Asan Bay. Net sediment transport pattern shows that sandy sediments in the Kyunggi and Asan Bays are generally transported landward from the outer sea suggesting sediment trapping inside the bays. This phenomenon may be related to the formation and maintenance of numerous sand banks in this macrotidal sea. Alternate occurrences of deposition and erosion predicted from the numerical model along the coast of the Taeanbando with strong deposition on the southwestern part of the 'Jangansatoe'(JSB), a large sand ridge off the coast of the Taeanbando appear to reflect the loose connection of JSB, The 'Joongangcheontoe', a central sand bank (CSB) with the main axis in the NW-SE direction in the Asan Bay may undergo a modification with strong deposition along the northeastern flank. These results indicate that the sand banks are actively modified and maintained by the strong tidal currents in this shallow macrotidal sea.
