Services are reusable units in business level. Ubiquitous computing provides computing services anytime and anywhere. The combination of both is becoming an important paradigm of computing environment. Fundamentals of services require flexibility and interoperability, and key elements of ubiquitous modeling require interoperability and context-awareness. There are two kinds of methods to identify services. The top-down approach is based on business process, and the bottom-up approach is based on components. The first approach depends on experts' intuitions, while the second approach suffers the incapability of expressing non-functional expression through components. Although a feature-based approach is capable of expressing non-functional expression and identifying services in ubiquitous environment, the research on this issue is not adequately addressed by far. To promote this research, this paper proposes a feature-based method to identify services in ubiquitous computing. The method extracts initial-candidate-services from a feature model. Then, the ultimate services are identified through optimizing and analyzing the candidate-services. The proposed method is expected to enhance the service reusability by effectively analyzing ubiquitous domain based on feature, and varying reusable service units.

Korean local governments have been planning for u-City construction with great efforts. Such efforts are needed in order to reflect the urban characteristics of each city, to promote local economic growth, and to have a sustainable operation model. Thus it is critical at an earlier stage to set a strategic direction based on urban environment analysis, which will lead to a feasible implementation of u-City. This paper derives issues and suggests improvement methods based on a case study on the USPs (u-City Strategy Planning's) of ten local governments. It is expected that the improvement methods will greatly reduce risks involved in u-City construction and contribute to better provided local-specific u-services.

The vision of ubiquitous computing is becoming a reality now .Service discovery in ubiquitous environment, as well as adding semantics to the data is quite established. But, not many researchers have thought about the management of these devices. We envisage that by integrating SNMP with service discovery protocols, we could leverage the use of management factors (like performance, fault and security management etc) in the business, organizations, and other multi-user environments.

Nowadays the research and development of various middleware for the ubiquitous computing environment has been demanded and many application services have been provided. The practical ubiquitous computing environment is the world where a variety of services based on RFID/USN devices are integrated with each other and make synergy effects all together. In the end user perspectives, there should be a middleware platform and business logic framework collaborating various services all together to satisfy the user requirements. In addition, the platform should provide the user to describe a scenario based on various event to maximize the collaboration. In this paper, we have proposed business logic framework which is supporting collaboration between heterogeneous service systems based on the user's scenario. We have also tried to show the efficiency and scalability of the proposed framework by providing the result of a couple of tests.

These days, information technology is rapidly changing our society. Thus, considering such a business environment, many companies are seeking revenue models for successful business. In particular, digital content with the convergence of culture and information technology create revenue for businesses. For this reason, many companies are interested in UGC (User Generated Content), which refers to various kinds of publicly accessible media content that are produced by end-users. Thus, this paper analyzed the attributes of UGC and businesses using ubiquitous technology. From this analysis, this paper shows the critical success factors for UGC in ubiquitous business environments. In addition, this paper analyzed the attributes of UGC through the research of literature reviews and expert reviews. Based on this research, many companies are encouraged to develop successful digital content generated by end-users.

Since the beginning of the 21st century, the power source for the growth of our country is shifting from the 'knowledge and information'-centered business to the culture-based business attaching importance to 'creativity'. In the era of creative culture-based economy, the core resources on which the national competitive power depends can be thought to be 'cultural contents'. The current ubiquitous project, which is being promoted in our country, is characteristically placing much emphasis on building-up of the RFID-centered infrastructure so that it is poorly acknowledged by common people to whom its service is actually provided. In this study, the approach to promotion of the cultural service, to which an easy access is available as a result of combining the ubiquitous-based technology with 'cultural contents', is discussed in the 4 aspects.

Evaluating ubiquitous computing services is important for the commercialization of the ubiquitous services which will be running on electronic markets. However, despite its importance and usefulness, assessing ubiquitous computing services is still in its early stage. Moreover, sufficient study of making a distinction what are 'ubiquitous computing services' or not has not been provided yet. Hence, this paper aims to propose an integrated methodology to assess the ubiquitous computing services. A multilayered approach is considered to assess not only technical but also behavioral perspectives. To show the feasibility of the assessment model, three use cases are studied and evaluated.

It is important that ubiquitous technology changes paradigm of thought, not simple definition in the 21st digital era. Characteristics of ubiquitous computing are pervasive, disappearing, invisible, calm through environment. As IT Technology develops, designers, computer scientists, chemists, performance artists cooperate in order to find out the best way to make desirable digital clothing in the future, with the merit of each part. Digital clothing defines clothes of new generation equipped computer, digital installations. Digital clothing design demands intercept of electromagnetic waves, light-weight and esthetic appearance, for it is attached high-technology equipment near body. The purpose of this study is to analyze design features of digital clothing according to ubiquitous characteristics. The methods of this study are documentary research of previous study and case study. In the theoretical study, ubiquitous characteristics are function-intensive by convergence, interactivity, embedded mobility and human & emotion-oriented attributes. Based on ubiquitous characteristics, digital clothing design classified function-intensive design by convergence, design for Interactivity and multi-sensible & emotion-oriented design, because embedded mobility is a basic element of ubiquitous environment. The early days digital clothing design is function-intensive design, and have esthetic appearances and design for interactivity increasingly. Recently digital clothing design is expressed multi-sensible and emotion-oriented design.

The ubiquitous computing environment is widely expanded in almost all industries such as transportation. physical distribution, manufacturing, communication, tourist industry, financial business, and so on. But the construction industry is not well applied yet. Thus this study investigate the ubiquitous computing environment and propose a way for applying this technology to the construction industry. To achieve this aim, this study consider about a instrumentation management of retaining wall system in earthmoving operations, and suggest the ubiquitous system configuration to measure the variance of retaining wall. Through this system, the efficiency of the instrumentation management of retaining wall will be improved.
