The Journal of Information Systems, volume 13, issue 1, 2004, Pages 1~20
Most of the software development projects bear risks that need analysis and management. Risk management plays a critical role for the success of software project management. In this study, we have used delphi method to delineate critical risk factors. The study pulls out 20 project risk factors from 21 project managers. It is certainly clear that certain features are more risky than others. Our study shows that unrealistic cost estimation and changes in scope and objective are more risky than other features.

Along with the advance of Information technology and the introduction of the information era, cyber education through the internet has been activated in universities and private educational organization. However, most cyber education is not being practically applied in government employ. This study looks at the influential factors of cyber education in order to create a cyberspace where the public official can obtain information at a place and time convenient to them. This will provide a chance to activate cyber education effectively. The hypothesis was approved through multiple regression analysis was executed in order to explain and predict the relationship between influential factors and cyber education effects. The results of the study show the influential factors of education effect as follows: - the instruction design and contents factors such as interesting educational contents, interaction between leamers and teacher, and positive instruction, all had an important influence. - the learner factors, such as a desire to leam, motivation, and interest in the lesson, also had a significant influence. - the environmental factors such as systematical basis and support, atmosphere, and consideration of others had a large effect on the education effect.

As a result of the fast development of Information communication technology, the competitive advantage of companies and the service quality of nonprofit organizations has been largely changed. Corresponding to this kind of change, companies have tried to make production improvement, competitive strengthening, and organizational innovation. Meanwhile, the nonprofit organizations directed by the government are pursuing the service innovation from general administration area to the public service for civilians. In relation to this, risk management of the company's information systems outsourcing has largely been studied until now. However, the study of risk management for nonprofit organization information systems outsourcing has rarely been made. In this paper, to provide the theoretical base for further research, we have attempted to develop the evaluation framework for risk management of information systems outsourcing considering the characteristics of nonprofit organizations.

Fixed-mobile convergence services can be defined as the combination of previously separate fixed and mobile services, and networks and commercial practices. Examples of fixed-mobile convergence services include single voice-mail box, single number and unified messaging across fixed and mobile networks. Recently as more voice is transferred to mobile networks, convergence services between fixed and mobile become more important. In Korea convergence services are only starting to become established, and are likely to become an important part of any operator's offering. In this paper, we search the different levels of fixed-mobile convergence services and the trends and regulations for fixed-mobile convergence services in major countries. And at the same time, we also suggest the corresponding Marketing strategies by operators related to fixed-mobile convergence services.

According to the increase of organizational complexity and the change of rapid information technology environment, many firms have shifted their information technology(IT) strategy from developing information systems in-house to purchasing application software such as Enterprise Resource Planning(ERP) Systems. Marketing and Sales functions within a Korean automotive part company include developing new assembly products, determining pricing, taking customer's orders, and shipping assembly products to customers. Marketing and Sales Information System(MSIS) in ERP system plays an important role in next Production Planning process. MSIS also makes management reporting and decision making faster and more uniform throughout an organization. MSIS promotes thinking about corporate goals, as opposed to thinking only about the goals of a single department or functional area. This paper intends to design and implement a MSIS in ERP systems for Korean automotive part company using object-oriented methodology In order to accomplish the implementation of MSIS in ERP system, we employed UML as its standard modeling language. In this study, four diagramming techniques such as use case diagram, sequence diagram, class diagram, component diagram among eight modeling techniques are used for analyzing hierarchical business process. In traditional marketing and sales function, a company with an unintegrated information system can have marketing and sales data that is data redundant or inaccurate. MSIS integrated in ERP system can solve the sales forecast problem, which minimizes the total costs of production, inventory, and transportation under constraints of production capacity. Also, the use of UML methodology makes S/W programmers shorten the phase of analysis and design in the implementation of MSIS system, and increase the reuse of software and the interoperability with corporate internal Information system.

Recently, many e-business companies started to charge fees to the use of information contents service. However, little is known about how users evaluate and determine to purchase information services. Past technology adoption research has focused primarily on the positive utility gains side, focusing on usefulness and ease of use. Purchase of e-service, however, involves not only the position utilities but also negative utilities. This research uses the service value model(SVM) and explains user's intention of purchasing a new information service. Based on the Perceived Value Framework, this research investigates the impacts of the service quality and the fee charge on the user's perceived service value and further on user's intention of adopting the e-service. One of the most important postulations of this research is that both service quality and the fee charge influence user's intention through affecting the user's perceived service value. This research presences a conceptual model of users' e-service evaluation process. The conceptual framework provides a basis for understanding how perceptions of quality and sacrifice influence value perceptions and purchase intentions. The results of an empirical research suggest that the both service quality and fee charge have influences on the perceived service value. However, they do not directly affect user's intention to purchase the e-service. They affect user's intention to purchase through affecting the perceived service value. In conclusion, this research provides a base to build on for other research studying use intention model of new e-service.

As Internet usage widely grows, online content services such as newspaper, magazine, music, game and movie are provided with a fee-based subscription. Many content services providers consider charging a usage fee into its service provisions as one of the Internet business models for increasing revenue. There are customer resistances to adopting the fee-based service provision on the Web. Previous research in information systems (IS)has focused on the analysis of adoption of information technology or systems in the individual ororganization level. No principle research has been carried out on the user adoption behavior of online content services provisions. As users actively access content services on the Web, it needs to explore user adoption behavior in different settings. Many IS researcher have employedquantitative approaches, even though they deal with the process of user behavior regarding the information technology or system. In this study, we attempt to discover how customers adopt the fee-based provision of online content services by employing grounded theory, one of the principal qualitative research methods.

In industrialised countries, innovation is a key source of economic growth. Rrsearch is a key driver of technological innovation and involves the process of systematic investigation and/or experimentation to discover new knowledge. The Governments'industry innovation policy supports a business focus on Research and Development (R&D) through a range of programs in order to achieve these aims. The Innovation Statement (DISR 2000, 20010, launched by the Australian Prime MinisterJanuary 2001, commits an additional
3 billion over five years to encourage and support innovation. The Australian Government aims toworld competitive firms and strong research capability in industry to strengthen Australia's international competitiveness and increase national prosperity. It develops policies and programs to enhance investment in innovation. The Australian Government has established a number of R&D funding support programs aimed at increasing the level of R&D in Australia. The backbone of these programs is the tax concession program, which is made up of the 125 per cent R&D tax concession, the 175 per cent premium tax concession and the tax offset. Over 4000 businesses take advantage of the tax concession scheme, which costs the government around
400mi11ion a year. This cost is expected to rise to over hall a billion by 2005-06 (commonwealth or Australia, 2003). Ensuring these resources are invested where they provide significant national economic benefits is a major policy issue. In this sense, this paper looks at the appropriateness, effectiveness and efficiency of the R&D tax concession with costs and benefits analysis.

The Journal of Information Systems, volume 13, issue 1, 2004, Pages 161~177
In the catalogs that have presently been under research, the product information cannot be represented in a classified form but it also fails to be well defined, lacking the description of detail information for various products on a systematic fashion. And the product information is duplicated on its representation. In this study, an implementing model is to be proposed to analyze and classify the information that can be in use of describing various products, and to describe an integrated products information for various types of products while making up for the weak points of presently available researches. Also, this study shows that it is possible for the proposed model to represent various units of product information with presently proposed model applied to computers and book products in high demand of transaction, and by implementing electronic catalogues in the existing researches to prove its efficiency.
