Recently many companies have increased their investment in IT because they are increasingly interested in taking advantage of IT and they recognized that it was a very important strategic resource that any organization should manage. That means that the members of a company or an organization realized the importance of IT specialists' coordinating and working in partnership with the business employees to ascertain the high quality and productivity through IT services. While the company looks at IT cost reduction, there is a pressure from users for more support and service from IT departments. That means IT service providers have to offer improved service quality at reasonable cost. To solve the contradictory problem, this paper proposes the application of IT service management. If the IT service management is implemented properly, an organization can attain the tangible and intangible results which are profitable and effective. In Korea, studies on IT service management have focused only on getting a certification and development issues, and there are few papers which accomplished empirical studies. From the viewpoint of Resource-based theory, this study reviews the definition of IT service management and its elements. It has demonstrated empirically how IT service management can have an impact on IT service management performance. As a result, IT service management plays a role in adding and improving the practical use and efficiency of IT service management. In conclusion, this study contributes to support and show the critical point of the previous literatures about IT service management and offers the new practical implications for business sectors.

According to adaptive structuration theory, faithfulness of appropriation(FOA), and consensus on appropriation(COA) are variables for measuring appropriation in use of IT. FOA is the level of interpreting and using the intentions of the IT designers objectively and COA is the level of agreement on ways of using IT among or with user group independently of designers' intention. In traditional theories of IT adoption, computer self-efficacy(CSE), self evaluation on abilities of using computer, has been considered as one of the important individual differences. which would influence on beliefs of using IT. Therefore, considering the relationship among CSE, FOA, COA and attitude, we can hypothesize that CSE would play a moderation varaible among appropriation related variables relationships, FOA-attitude and COA-attitude. The objective of this study is an analysis of CSE's moderation effects in causality relationship among appropriation measuring variables. For this purpose, we propose a research model where there are four hypotheses for moderation effects of CSE on the relationships between appropriation variables. We test these hypotheses by sampling ERP and groupware users. In result, our proposed hypotheses except moderation effect of COA-usefulness are accepted. Main contribution of this study is to identify the relationship between CSE and AST. This study implies that very careful consideration of users' CSE is necessary in order to perform managerial activities based on FOA and COA in IT management department.

The economic growth that depended on IT industry is reaching to a limit. In order to overcome the limit, the convergence industry that makes new market and products is essential. However, companies preparing a jump into the convergence industry must understand the exact visions and characteristics of convergence. Therefore, we investigated the structural changes of industries caused by convergence and importance characteristics of convergence. Also, we demonstrated the current status of the convergence industry and analyzed economical, social/cultural, and technological environments that the companies are facing, and elaborated the opportunities of convergence. At last, we suggested basic requirements and strategies for companies starting a convergence business and IT utilization methods to accelerate the convergence business activation.

In customer-oriented make-to-order manufacturing environments, the works of BOM changes due to the changes of product specification and engineering are closely connected with almost all departments such as sales, engineering, production, procurement, cost, after service, etc within an enterprise. So, the contents of BOM changes must be instantly reflected on the related works among the departments. To effectively process these complex works of BOM changes, types of changes on product specification and engineering and types of BOM changes linked with those must be systematically defined, classified and managed by information systems. Thus, it is necessary to introduce solutions such as BPM and SOA in order to efficiently deal with complex business processes like BOM change management. This paper proposes a methodology of constructing information systems based on BPM and SOA. The proposed methodology defines the relationship between processes of BPM for definition, execution, monitoring, etc of business processes and services of SOA for connection among information systems within an enterprise, and presents a scheme of practically applying BPM and SOA solutions to actual business works. To show an utilization of the proposed methodology, the prototype system for product BOM management is implemented in order to efficiently deal with the works of BOM changes due to the changes of product specification and engineering.

This study proposes a framework for an evaluation and selection of a venture firm with promising new technology in optical electronics industry to nurture that firm. The framework is intended to help practitioners to evaluate accurately and objectively new technologies. In addition, this study tests the usability and effectiveness of this framework with an actual certain case. More specifically, this study, first proposes that the framework for new technology evaluation is composed of financial perspective, market perspective, internal business perspective, and R&D and growing perspective. They are on the four perspectives of BSC(Balanced Score Card). Each perspective contains specific items. In addition, this study uses AHP(Analytic Hierarchy Process) to assess the comparative importance among the four perspectives and their specific items. Secondly, based on the results of AHP, the usability and effectiveness of the framework suggested in this study have been tested with a real case evaluating and selecting a promising venture firm. The results of the study have the following implications: this study has developed the framework for new technology evaluation which assists practitioners. Our framework offers the four perspectives and their specific items with their respective comparative importance. Furthermore, this study has verified that the proposed framework can be applicable in real situation with more accurate results.

Government uses the Internet technology to create electronic Government(e-Government). E-Government is an on-going project, and it represents a strong intention of Korean government to make effective and smooth communication between Korean government and its people. To achieve this purpose, government portal sites is one of projects of e-government, being a common gateway for users to find information and to communicate with the government concerning many matters/any matter. However, user's attitudes and behaviors explaining why they intend to use government portal sites is a scant. Therefore, the main purpose of this study is to investigate empirically the determinants influencing users' intention to use government portal-sites. Starting with DeLone & McLean's Updated Information Success Model(2003), this study suggests three qualities(Information Quality, Systems Quality, and Service Quality) and two moderating effects(Ambiguity and Government Supports), which affect the perceived usefulness of government portal sites. Results show that the hypotheses were supported. The findings of the study suggest not only a new theoretical model for IS research, but also the important indicators of a successful usage of e-Government portal sites.

If industrial disasters happen at workplace, work's desires of workers and business activities may be dispirited. Especially, industrial disasters frequently happen in the field of heavy and chemical industry companies. According to report of the korea occupational safety and health agency(KOSHA), damage due to industrial disasters is more 5 times than losses due to industrial strifes. Thus, in these manufacturing companies, a safety management field for preventing industrial disasters is emerging as an important factor of business activities. This paper proposes an industrial disaster prediction model for safety management and also implements industrial safety management system(after this, is called as u-Safety system) based on the proposed model using ubiquitous computing technologies like USN(ubiquitous sensor networks) which are given much attention among recent information technologies. The implemented system is successfully operating in the shipbuilding division of 'H' companies.
