An Empirical Study on the Development of Behavior Model of Insurance Fraud
Lee, Myung-Jin ; Gim, Gwang-Yong ;
Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 1~18
Many researches have been done in insurance fraud as the amount and frequency of insurance fraud have been increasing continuously. In particular, the development of insurance fraud detection system using large database management techniques including data mining or link analysis based on visual method have been the main research topic in insurance fraud. However, this kinds of detection system were very ineffective to find unintentional insurance fraud happened by accident even though it was so good to find intentional and organized crime insurance fraud. Therefore, this research suggests insurance fraud as an ethical decision making and applies TPB(Theory of Planned Behavior) for the finding of reasons and prevention strategies of unintentional insurance fraud happened by accident. The results of research show that TPB is very appropriate model to explain the behavior of insurance fraud and that insurance agents force to do insurance fraud as affecting perceived behavior control. Therefore, education and pubic relations for insurance fraud are very effective for preventing insurance fraud and developing insurance service industry.
An Experimental Study on the Price Discrimination on the Internet: The Effect of Illusion of Control and Lateral Customer Relationship on Price Fairness
Lee, Zoon-Ky ; Lee, Ji-Hae ;
Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 19~33
The current advance of IT and the e-commerce triggers the wide practice of dynamic pricing in all industries although the price discrimination has been very cautiously applied in the limited areas in the past. The price discrimination which offers different prices for each customer depending on their preference and buying behaviors has recently gained attention as it could provide superior benefits to sellers. The wide adoption of price discrimination, on the other hand, is reported to face buyer resistances and complaints. Our limited understanding on the perception of price fairness, which we think is key concept in the price discrimination on the Internet-enabled transactions, motives us to investigate factors that affect the perception of price fairness. This study focuses on illusion of control and lateral customer relationship to investigate their effects on price fairness in online auction and group purchase context. By conducting laboratory experiments, our study demonstrates that customers' perception on illusion of control in price determination and advantageous lateral customer relationship significantly affect price fairness perception in both online auction and group purchase environment. The findings are expected to provide researchers and managers with useful insights to develop better pricing strategies and design effective dynamic pricing mechanisms.

Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 35~47
The purpose of this thesis is to analyze the success factors of ERP system in corporations and to know what is different in the factors depending on organizational culture and size. Considering there are various results from introduction of the same information technology(IT), it is implied that organizational characteristics make a difference. In this thesis we did factor analysis and multiple regression about the factors based on the previous studies and analyzed the priorities depending on organizational culture and size. The results show that mechanistic organization has key success factors of work process change, project team abilities, and determination of CEO while organic organization has those of work process change and project team abilities. Plus bigger sized organization has success factors of work process change, project team abilities, and determination of CEO while small sized organization has those of work process change and project team abilities.
Characteristics and Performance of ERP Adoption in University Organization
Cho, Sung-Eui ;
Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 49~62
Characteristics of the motivation and performance of Enterprise Resources Planning (ERP) adoption in university organization are explored through case studies in this study. Generally, the modules for production, sales, and logistics management in a manufacturing company are substituted with new modules for student support, lecture operations, and research management in ERP for university organization. The motivation of ERP adoption is closely related to the purpose of improvement of business process operations and information system control rather than the environmental factors such as inter-organizational competition or increase of market uncertainty, differentially from enterprises cases. In addition, the financial performance such as cost reduction, labor substitution, and increase of productivity is relatively lower evaluated than the performance on organizational aspects or information system control.

Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 63~80
In this paper, the function factors contributing to ITA/EA functions in their organizations, are suggested. Also the reasons to the construction of IT governance system and their effects on the their organizations are discussed and the relationships are verified by empirical model. From the survey, the data of the 227 respondents were collected and regression analysis was performed for validating the research model. ITA/EA functions consist of the IT infrastructure systemization, ITA/EA business process support, IT investment efficiency factors. And the factors of IT resource and performance management, IT process management, IT service management are included to IT governance. The main analysis results described significantly are shows as follows. At first, IT resource and performance management factor is effected by the ITA/EA business process support factor and IT investment efficiency factor. In similarly, IT service management factor is also affected by the factors such as ITA/EA business process support, IT investment efficiency, and IT infrastructure systemization. In additional analysis, IT investment efficiency factor in official sectors, ITA/EA business process support factor in private sectors respectively are described as the significant factors on the IT governance.

Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 81~97
Nowadays, IT becomes one of the core competencies in a business. So defining appropriate responsibilities & roles of IT human resources as well as setting the professionalism of them is getting more important. However, there are lots of problems between the supply and the demand of IT human resource. The efforts to arrange workers who have expert knowledge and skill in right place are needed to strengthen national competitiveness. Recently, several leading countries are setting IT skill standards to solve such problems. Therefore, this paper aims at analyzing IT skill standards of developed countries such as ITSS of Japan, SFIA of United Kingdom, and SSIT of USA. By doing comparative analysis of current status of Korea with them, we derive some meaningful insights to develop a national IT skill standard.

In ubiquitous computing environment such as ubiquitous marketplace (u-market), there is a need of providing context-based personalization service while considering the nomadic user preference and corresponding requirements. To do so, the recommendation systems should deal with the tremendous amount of context data. Hence, the purpose of this paper is to propose a novel recommendation method which provides the products-group list of the customers in u-market based on the shopping intention and preferences. We have developed FREPIRS(FREquent Purchased Item-sets Recommendation Service), which makes recommendation listof product-group, not individual product. Collaborative filtering and apriori algorithm are adopted in FREPIRS to build product-group.
A Study on Web Services Selection and Conditional Branches
Seo, Sang-Koo ;
Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 125~143
IT Services market is growing rapidly in the business industry and SOA-based Web Services have been introduced as an effective vehicle for the integration of enterprise-wide applications within organizations. The number of publicly available Web Services is ever increasing recently in a variety of areas, and as the number of public Web Services increases, there will be many Web Services with the same functionality. These services, however, will vary in their QoS properties, such as price, response time and availability, and it is very important to choose a right service while satisfying given QoS constraints. This paper addresses the issue of selecting composite Web Services which involves conditional branches in business processes. It is essential to have any conditional branches satisfy the global QoS constraints at service selection phase, since the branches are chosen to execute at run-time dynamically. We proposed service selection procedures for basic structure of conditional branches and explained them by examples. Experiments were conducted to analyze the impact of the number of candidate services and service types on the time of finding service solutions.

This paper describes an extension of Kaffe JVM which enables to extract runtime characteristics of a Java program. The runtime characteristics include frequency of method call instruction, ratio of library method call and ratio of method whose runtime is less than compile time. It also represents ratio of method called only once, polymorphicity of virtual call and distribution of method size called in runtime. This paper analyses runtime features of the SciMark benchmark suite using the extended Kaffe.

Middleware for mobile devices, embedded middleware, is used for mobile devices, cellular phone and DMB related services. It is essential for middleware providers to provide high quality middleware in conformity with its standard and interoperability on hardware platforms. The standard conformance and interoperability of embedded middleware are the key factors to make service providers succeed in their business. The quality of embedded middleware could be secured when Tests for the standard conformance and interoperability of embedded middleware are performed with well established test framework. In this paper, we describe middleware testing methodology of standard conformance, interoperability and middleware test framework for mobile devices.
The Design and Implementation of a Performance Evaluation Tool for the Face Recognition System
Shin, Woo-Chang ;
Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 161~175
Face recognition technology has lately attracted considerable attention because of its non-intrusiveness, usability and applicability. Related companies insist that their commercial products show the recognition rates more than 95% according to their self-testing. But, the rates cannot be admitted as official recognition rates. So, performance evaluation methods and tools are necessary to objectively measure the accuracy and performance of face recognition systems. In this paper, I propose a reference model for biometrics recognition evaluation tools, and implement an evaluation tool for the face recognition system based on the proposed reference model.

Lee, Kyu-Woong ;
Journal of the Korea society of IT services, volume 6, issue 2, 2007, Pages 177~188
Policy-based Network Management (PBNM) has been presented as a paradigm for efficient and customizable management systems. The approach chosen is based on PBNM systems, which are a promising and novel approach to network management. These systems have the potential to improve the automation of network management processes. The Internet Engineering Task Force (IETF) has also used policy concepts and provided a framework to describe the concept as the Policy Core Information Model (PCIM) and its extensions. There are policy conflicts among the policies that are defined as the policy information model and they are not easily and effectively detected and resolved. In this paper, we present the brief description of PBNM and illustrate the concepts of policy core information model and its policy implementation for a network security. Especially we describe our framework for detecting and resolving the policy conflicts for network security.
