u-Park means national parks with environmentally sound information networks and integrated ubiquitous services are available. u-Park is totally managed based on u-IT (Ubiquitous IT Technologies) which provides ubiquitous service through sophisticated resources of national park and establishments. It is necessary in changing the existing park management system into u-IT based u-Park management system that park managers should accept new technology, u-Park management system, and be able to utilize it. The purposes of this research is to analyze managers' acceptance behavior on ubiquitous computing technology. Technology acceptance model (TAM) was introduced to specifies the causal relationships among variables related to managers' technology acceptance behavior. The hypothesized model was tested by surveying 157 managers at 5 national parks in Korea. TAM accounted for 55.2% of the variance in intention to use. The most important finding is that perceived compatibleness was the most influential variable in determining intention to use. This means that u-Park management system should be compatible with manager's task and business style.

Purpose - International diversification, a critical issue in research and practice, undoubtedly represents a growth strategy with great potential impact on firm performance. Although the literature has widely examined the relationship between international diversification and firm performance in international business and strategic management research, it remains unconfirmed. This study, therefore, aims to clarify the relationship as it relates to information service firms. Research design, data and methodology - To examine the international diversification-performance relationship, this study uses a sample of major Korean service firms spread over four industries spanning a period of five years between 2005 and 2009. In this study. generalized least square was used to analyze the relationship between international diversification and performance of service firms. Result - The result showed the U-shaped curvilinear form between international diversification and performance in service firms. Especially, IT service firms may differ from other service firms that the negative effect of internationality may have weaker than other types of service firm. Conclusion - Based on the empirical results, the U-shape relationship between international diversification and performance is confirmed in Korea service firms. Furthermore, information service firm may reduce the initial internationalization cost by transferring codified and digitized information using information and communication technology, so that gain benefit from early international expansion.

The purpose of this paper is to analyse the present situation and legal problems of u-health. U-health plays an important role in enlarging the healthcare service and making the healthcare service efficient. The use of Korean excellent IT technology can lead us to a world wide competitive healthcare industry. Although u-health has the weakness in privacy protection, the usefulness and convenience of u-health is great. Therefore we must analyse the legal issues of security technology, RFID, telemedicine and EMR pertaining to u-health and construct the appropriate legislative structure to resolve the legal problems of u-health.

RFID is estimated to have great potential for hospitals to reduce various costs, reconsider patients' safety, and provide high quality medical service. As the ubiquitous technology allows the medical market to expand, medical centers all around the country are fiercely competing against one another. In order to increase the hospital's competitive edge by reducing IT expenses and concentrating on medical practice, the need to establish a u-Hospital using advanced IT technology is rapidly rising. This paper implements an RFID based u-Hospital system by using ubiquitous computing technology to design a location tracking device for all surgical patients, which can secure the patients' safety and increase the quality of medical service through interlocking hospital information systems.

The Ubiquitous Healthcare business are growing recently by medical service development. According to this environment, many healthcare service model have been studying and suggested. At the same time, medical world market has been reorganized into a traditional medical science out of the west medical science. But in spite of this trend, domestic U-Healthcare market in traditional medical science is for lack of profit service model. So it is true that the presentation is demanded from oriental medicine U-Healthcare service model these days in oriental field. Thus, in this paper we propose the healthcare service model that can be applied to the oriental field efficiently. Our method is based on fuzzy rule method that analyze the patient data by CDSS processing. In experiment, proposed method is more profitable and efficient than west service model. For future works, we will research about the standardization and security of processed data.

Recently, the area of ubiquitous has gained a great attention both in academics and in business organizations as we are entering an ubiquitous society where people can interact at "anytime" and "anywhere". To preoccupy the leading status for the next generation of IT technology, many countries such as Korea, Japan, and US are concerned the ubiquitous. In this tendency, companies want to identify what factors make people use ubiquitous in order to develop the effective ubiquitous service and to supply the higher quality service. However, prior researches on ubiquitous are focused on technical area such as higher data delivery, efficient compression of images, so they do not have given companies beneficial materials for making fascinating ubiquitous services. To offer the service materials for development, from the viewpoint of the customer, important factors to use ubiquitous services are investigated in this study. Moreover, the study was progressed up to the new area of investigation how much these factors influenced ubiquitous service actual usage. To achieve these goals, Ubiquitous service adopting reflected in ubiquitous service characteristics was suggested in this study. The results of this study are as follows. First, contextual offer, ubiquity, invisibility are positively related to perceived value. Second, perceived value is positively related to usage intention but perceived risk is negatively related to usage intention. Third, usage intention is positively related to usage frequency. Based on these results, managerial implications for ubiquitous service vitalization are discussed. Lastly, the limitation of this research and further research issues are suggested.

This study was to analyze the influences of various factors on the u-health service. Data was surveyed from experienced of u-Health service sectors. We measured legal support, IT-infra, user education, the user education, and the u-Health solution, are the critical success factors for the u-Health service. Also we evaluated u-Health services by survey data from the users. We did also the research to evaluate the validity and reliability of these factors. After that the Analytical Hierarchy Process (AHP) was applied to measure the weights among these factors. Factor analysis resulted in 6 major factors (Eigenvalue > 1.0). The AHP analysis showed the list of Critical Success Factors weighted by its significance priorities. The results of this paper could be the valuable references for the policy making process of the u-Health system in Korea.
