In order to enhance competitiveness in the industry, financial companies are building a high level of customer satisfaction and repurchase intention by further strengthening not only the technical quality of the platform business but also the customer-oriented service quality. Theoretically, it is time for a theoretical review of whether the expansion of service quality using platform business in the financial industry is directly linked to the performance of financial companies, such as satisfaction and repurchase intention of existing customers. Based on the rapid growth of mobile and the main activities of financial platform companies above, This study attempted to test a significant impact on customer satisfaction and reuse intention on information services and system services, which are service quality of mobile financial platforms. Even if a number of financial companies compete with each other, they could survive by dividing the market, In the digital environment, customers have free access, so the winner can monopolize the market. It is an environment in which customers can move to platform companies that provide better services. The contents presented through the results in this study will be able to be used strategically in terms of the implementation and operation of the financial platform. In addition, it served as an opportunity to find independent variables that affect customer satisfaction and reuse intention, which are financial platform service quality, and suggested the possibility of continuous development of the platform in the future. In summary, the service quality of financial platforms can further expand users by emphasizing user visibility in terms of information services and utilizing user-centered financial platforms that increase customer satisfaction and reliability by strengthening the responsiveness and ease of system services. This study is of important value and is believed to have laid an important foundation for future research.

In this paper, we analyze an M/G/1 two-phase gated service model with threshold. We consider compound Poison arrival Process and general service time, where the server fives two different modes of services in order, batch and individual services. Server starts his service when the number of arrived customers reaches the predetermined threshold . We find the PGF of the number of customers in system and LST of waiting time, with which we obtain the means of them.

Recently, Certificate has been loosed 100 times in a four years as Phising or hacking. The service that use certificate in financial services occurs practical and secure issues. Therefore, the Korea government abolished the mandatory system used in the certificate service. However, they did not provide a replacing method for a certificate. And is not to fill the gaps of the certificate with one time password or secure card. Therefore this paper is propose the alternative method with total authentication service, that is lead the more secure electronic commercial.

We consider the $P_{\lambda}^M-service$ policy for an M/G/1 queueing system in which the workload is monitored randomly at discrete points in time. If the level of the workload exceeds a threshold ${\lambda}$ when it is monitored, then the service rate is increased from 1 to M instantaneously and is kept as M until the workload reaches zero. By using level-crossing arguments, we obtain explicit expressions for the stationary distribution of the workload in the system.

To transform the enterprise system into the 'Real Time Enterprise' with respect to IT, I suggest the conceptual application model which is composed of pieces(components) extracted from different packaged applications working in a heterogeneous environment based on the 'business activity' in other words, business services provided by internal (inter-enterprise) and external (extended enterprise) application to support a business activity within in an enterprise and the design mechanism focusing service tier which acts as intermediate tier within application architecture.

The main idea behind the Intelligent Networks (IN) concept is the separation of switching functionality from the service control, in order to meet various service requirements of subscribers and development of new services in time. On the increase of subscriber and for high quality of service, the IN upgrades its service systems, and there are a number of ways depending on the system architecture and the characteristics of services. This paper compares two alternatives, traces the performance of them by means of the simulation technique, and finally puts a rule to select one of them.

An exact solution technique for M/M/s multi-server demanding queue is introduced, and a general form of the curves representing service rates of the system is presented. As the number of customers in the system increases, the service rate is shown to increase initially, then decrease, and finally converge to a certain value. It is also shown that this phenomenon persists regardless of the numbers of servers and customer types.

This thesis examines the problems faced in the electronic trade specialized service provider for which improvements are necessary, and suggests various ways of overcoming those problems. First, from the legal aspect, it is necessary to clarify the scope of duties as well as to expand the threshold for entrance and business areas through the amendment of related laws. Second, from the operating aspect, the e-trade specialized service provider should be able to provide convenient work spaces through user-centered interface by connecting, integrating, automating and simplifying various services scattered around through the establishment of an operating system. Third, from the institutional aspect, trade firms should be able to perform e-trade duties without difficulties by specializing and increasing the size of the e-trade specialized service provider system and strengthening job competence. For this, it is required to improve legal registration requirements to enhance the reliability of the e-trade specialized service provider system and secure its financial capacity.

Evaluating a project is one of the key activities in managing projects, and thus it should be implemented as a part of the entire project management system. However, currently deployed systems suffer from deficiencies such as the lack of supporting distributed environment and integrity problems. Web service technology, which enables applications to work inter-operatively under a distributed computing environment, is said to solve such problems. In this paper, the web service technology is applied to evaluation management systems. The process of evaluation is designed based on the web service, data is modeled and a pilot system is implemented to test the feasibility of the technology to the domain of project evaluation.
