The IT convergence industry is expected to create some high added-value, yet the IT convergence service is still in its introductory stage, which requires the utilization of yet to be tried future technologies and development methodologies that have been never tried in the past; therefore, there is certain risk involved regarding the success of development during the introduction of service and the development of technology. From such perspective, this study found examples of the services in the IT convergence industries and the application technologies for the realization of those services; and conducted a research based on the examples, using the technical Characteristics classification; and based on the result, analyzed the standards and the peculiarity of technologies employed for the IT convergence service and the correlation and the complementarity between them; also identified the standards and the peculiarity of technologies required by the IT convergence services and analyzed the correlation between them; and finally analyzed the compatibility between the IT convergence services and the applied technologies. The conclusion of this study is expected to be utilized for selecting technologies for the introduction and the operation of the optimal IT convergence service and as a benchmark as well.

Regional INformation Network Center has constructed integrated VAN among the heterogeneous computers and core technical information database for machinery & materials-oriented enterprises in the Changwon & Masan Industrial complex. As the result of RINNet project, regional industrial companies can take advantage of getting core technical information for developing new technology and strengthening competitive power. Accordingly, RINNet(Regional INformation Network for science & technology) makes regional industrial companies possible to collect, acquire and use technical information rapidly and motivates regional society to form the rapid technical interchange system and cooperative system among industrial-educational-institutal complex.

Recently, the number of patent applications have been increasing rapidly every year as the importance of protecting intellectual property rights becomes more important. Patents must be inventive and have novelty. Especially, the novelty implies that the corresponding invention is not the same as the previous invention. To confirm the novelty, prior art search must be conducted before and after the application. The target of prior art search should include not only Korean patents but also foreign patents. Search of foreign patents should be supported by multilingual search techniques. However, a dictionary-based naive approach shows a limitation because some technical concepts are represented in different terms according to each nation. For example, a Korean term and a Japanese term may not be synonym even though they represent the same technical concept. In this paper, we propose a new method to map semantic similarity between technical terms in Korean patents and Japanese patents. To investigate different representations in each nation for the same technical concept, we identified and analyzed pairs of patents those are mutually connected with priority claim relationship. By performing an experiment with real-world data, we showed that our approach can reveal semantically similar technical terms in other language successfully.

The aim of this study is to find the model that best explains members' continued use intention in virtual communities by comparing technical and social perspectives applied in IS context. With the eight major variables identified from prior studies, four alternative models were formulated:1) A base model from Information Systems (IS) continuance perspective, 2) IS continuance model with technology-acceptance perspective, 3) IS continuance model with social-capital perspective, and 4) IS continuance model with socio-technical combined perspective. The adequacies of these four models with different perspective highlighted were tested using survey data collected from virtual community users in Korea. The findings indicated that the IS continuance model and social-capital perspective is the most efficient model that best explains the members' continued use intention in virtual communities.

The objective of this study is to suggest the effects of the fit between project managers' competency and leadership style on the performance of IT projects. Also, this study examine that the project duration among the project's characteristics moderates the impact of the managers' competency and leadership style on the performance of IT projects. As the results of analysis, we found that the participative leadership and the supportive leadership of project manager is affected by the human and the conceptual skills, and the directive-achievement leadership is affected by the technical skills positively. The project duration moderates the impact of the fit between the participative leadership and the technical skills. and the fit between the directive-achievement leadership and the technical and the human skills positively.

Despite the growing interest in technostress phenomenon of employees in organizations, few guidelines exist about how mangers can effectively control their technostress. Accordingly, scholars should pay greater attention to how firms can successfully manage employees' technostress. This study conceptually developed and tested a research model for understanding the influence of technostress on psychological and behavioral strains. In addition, we tested technical support provision as a moderator. We obtained 107 samples through a survey questionnaire, and data were analyzed based on structural equation modeling (SEM). As a result, it was empirically demonstrated technostress decreases job satisfaction and individual productivity. We also found that technical support provision have moderating effects on the relationship of technostress and job satisfaction/individual productivity.

CALS, being widely adopted by industry, is a strategy to share integrated digital product data through a set of standards to achieve effieciencies and competition in business. For CALS implemetation, creating a shared information system is necessary and CITIS is proposed for that. CITIS shall provide on-line access and automated exchange of all the technical information between contractor and service provider, and the function of CITIS is difined in MIL-STD-974. In this paper, regarding CITIS as a infrastructure of information for CALS, we proposed CITIS server system which comprise global data sharing software, global data management system, workflow manager, and configuration management maneger.

As the functional and nonfunctional requirements of defence systems become more complex and precise, concerning about the systematic development of software embedded into the defence systems has become surged up. In order to develop more reliable and correct software, and to extend the life cycle of the developing software, adoption of some engineering technologies such as development process, methodology, CASE tools and documentation is essentially required. This paper introduce an approach to technical information management in embedded software development process, with an instance, airborne ECM system development project. Particularly, we suggest and explain how to guide the software development according to process and methodology, and how to generate technical documents using CASE tool.
