ERP systems are comprehensive sorfware packages that seek to integrate the complete range of lbusiness processes and functions in order to present a heuristic perspectives of a firm from a single information and information technlogy architecture. The ERP systems have delicate internal controls with built-in devices. It is known that the delicate internal controls help to enhance the accounting transparency. We empirically investigate the relationship between the ERP systems inplementations and an accounting transparency. In order to measure the accounting transparency differences, we compare the ERP systems implementation firms with firms which did not implement the ERP systems by 6 financial ratios (accruals, net profit margin, operation cash folo to sales, total debt to equity, accounts receivable changes, assets quality). Data are collecte from 135 firms implemented the ERP systems and 135 firms non-implemented the systems (the firms listed in the Korea Stock Exchange). We analyze financial statements from 270 firms for the period 2001-2003 to ezamine the 6 financial ratios differences. The results of 810 firms analyses over the 3-year period indicate that the ERP systems implementation firms show the statistically significant differences in the accrual ratio, the net profit margin ratio, operating cash flow to sales ratio, and total debt to equity ratio from the ERP systems non-implementation firms. But there is statistically no differences between the two groups for accounts receivable changes to sales ratio and assets quality.

This study suggests improvements in the management performance of the five largest exhibition and convention centers in Korea through financial ratio analysis. For this research, the financial ratios of each center were compared to the average of the centers as well as to the overall industry average during the past five years. According to the analysis results, the stability and growth ratios of the centers were excellent, but the profitability and activity ratios were poor. In particular, the ratios of profitability were in state of urgent need for improvement because they were at the level of severe deficits. It was analyzed that sales increase can be the key factor to improve centers' operation income and net profit to improve profitability. This study recommends measures to increase sales by using centers' facilities and their functions. The first is to actively host large-scale international meetings and conventions that only exhibition and convention centers can accommodate. The second is to attract brand exhibitions through strategic alliances with global Professional Exhibition Organizers (PEOs). Lastly, it is to organize sports and cultural events that are appropriate for incentive tours of associations and corporations.

Recent studies on business performance in the operation of travel agency services note the importance of non-financial factors, in addition to financial factors. They also indicate that in order to enhance the business performance in travel agency services, it is necessary to emphasize the most competitive key factors based on the understanding of the circumstances with which those services are faced. The analyses of business performance in travel services and of related research Papers have showed that the major factors influencing the operation of travel agency services include the relationship with tourism-related companies the introduction of e-commerce and knowledge-based management, the services of employed workers, and brand awareness and advertising. The present study attempts to propose an approach to the efficient operation of travel agency services by reviewing and analyzing the different studies regarding these factors. To do so, this study employs the existing study reports and publications related to the operation of travel services, focusing mainly on literature review. The paper is composed of four chapters: The first is an introductory chapter; Chapter 2 provides the theoretical background; in Chapter 3 an analysis of the previous studies is attempted; and Chapter 4 presents the results of analysis and other considerable suggestions.

The automated teller machine (ATM) is developed as a system to provide customers with an easy deposit and withdrawal of their money without time restriction and be served for 24 hours. Today, ATM is come up to the level of an unmanned branch. The automatic financing system is developed as an essential one for dealing with the rationalization of management and the globalization of financing in order to improve the efficiency of financial management work and increase the customer service quality. With reducing the operational cost of financial organizations through the efficient maintenance operation of ATM and increasing the service quality through the maximization of its processing efficiency, this study is to draw the scheme to ensure the competitiveness among the finance companies. The importance of ATM is highly recognized as the utilization of ATM is increased and the processing function is extended, but ATM is quite vulnerable to the malfunction occurred during the nighttime after banking hours. The ATM maintenance is done through consignment to the specialized maintenance company. The efficient operation of ATM maintenance work is important to the satisfaction of customer using ATM in the nighttime.

The IS project is getting more and more complicated and large-scaled. Many researchers and practitioners are interested in the IS development methodologies, automated tools and techniques, TQM to decrease project failure, and to increase IS performance. But, in spite of such various efforts, the latest Standish Group's research indicates that the project scale is bulkier than $1{\sim}2$ year ago and IS development project's batting average falls from 34% to 28% at the same time, proceeded project is increased, and project discharged arrives to $15%{\sim}18%$. According to a research, success possibility increased by 37% after a year of PMO introduction, and increased sharply by 62% after 2 years and by 65% after S years. This research has a goal to survey how the PMO function and operation type affect the IS project performance in the financial industry. I determine nine independent variables and three dependent variables from previous researches. The results of this study are that the four core functions of PMO have relationship with project performance. But, technical support function does not relate with organization performance. Among the four core PMO operation types, three types have an effect on the IS project performance except the perfectionist type.

We have been developing a method to build one-step-ahead prediction models for time series using genetic programming (GP). Our model building method consists of two stages. In the first stage, functional forms of the models are inherited from their parent models through crossover operation of GP. In the second stage, the parameters of the newborn model arc optimized based on an iterative method just like the back propagation. The proposed method has been applied to various kinds of time series problems. An application to the seismic ground motion was presented in the KACC'99, and since then the method has been improved in many aspects, for example, additions of new node functions, improvements of the node functions, and new exploitations of many kinds of mutation operators. The new ideas and trials enhance the ability to generate effective and complicated models and reduce CPU time. Today, we will present a couple of financial applications, espc:cially focusing on gold price prediction in Tokyo market.
