There are many researches to build up ubiquitous environment by the Ubiquitous Sensor Network(USN). These applications, such as home network, health care, natural environment and agricultural areas, are implemented by an embedded system. Their fields are gradually spreading. However the power consumption in its implementation plays an important role on the surrounding environment of the wireless network. In this paper, we design low power processor based sensor node platform for agricultural applications. We also compare its some performance with existing products.

Interaction requires dynamic relationship between objects. In ubiquitous computing environment, interaction between human and the environment is implied. Tactile interaction has so far been less addressed, while tactile sensation should be an important topic in the field of multimedia study. This paper describes development of a novel PVDF (Polyvinylidene Fluoride) dynamic tactile sensor and associated experiments. PVDF dynamic tactile sensors detect touch events applied to the sensor skin by low frequency components of the signal. Rubber skin-covered sensing material was mounted on the bones. Robust performance with low noise was figured out in our robotic experiment. Whereas most conventional sensors are interested in measurement, our dynamic tactile sensor is sensitive to change of state, which could be a key for economic understanding of happenings in the dynamic world. We note that dynamic sensing uses motion as a part of sensing modality We suggest that dynamic sensing be understood in technological terms in the perspective of interactive media and ubiquitous computing.

This study is to analyze the implications of effective learning in a ubiquitous environment. Research proceeded according to the multiple case study analysis method. This paper is one result of the Korean case study to examine the effectiveness of and satisfaction with u-learning. We will introduce necessary conditions for effective learning in a ubiquitous environment. Each condition was elicited through the case study, and the analyzing framework was classified into hardware related to infra structure; software such as learning contents, teaching-learning activity and support, and class management; human-ware related to learner and teacher; system-ware as an education system, and administrative supporting.

In the ubiquitous environment, the interoperability among the several agencies or systems can be realized by the common information model of the applications The common information model plays role of the core in the several application. In this paper, we proposed the ubiquitous information model as the core and developed the ubiquitous information markup language can be used to the any ubiquitous environment.

This paper reviews a new kitchen space by analyzing the user life style and their house environment where ubiquitous system is considered. The kitchen space where ubiquitous system is applied was differ in their house atmosphere and the role of kitchen area. Those changes under ubiquitous system has the kitchen becomes the central space of the house and the furnishings including home appliances and furnitures. This furniture and built-in machine will get a communication ability with user in the living and kitchen space. And it will include a high technology like as RFID, home network and so on.

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.

The rapidly developed environment by ubiquitous computing make the paradigm from e-trade to u-trade. The purpose of the study is to find out issue and the strategic suggestions that could link together between the e-trade and ubiquitous computing in side of information security. The study include the contents as follows; firstly, the technical explanations under the ubiquitous computing, secondly, e-trade's risks in security technology and lastly, issue and strategic suggestions how link them together in integrated view.

This study suggests a trial system for facility monitoring technology on ubiquitous environment. The trial system can be used for integrated various collection and sending data by bluetooth and wireless network from bridge. We used smart sensor and wireless network for it. Especially, we analyzed out all appliable technologies at monitoring part on ubiquitous environment and gave a standard spec to build the system. We wanted it as a guideline to apply ubiquitous in smart facility monitoring part.

Ubiquitous space can be described as a combined space of physical space and digital space. Ubiquitous space possesses new possibilities by combining the two. The concept of ubiquitous home will bring new changes in residential space design. First of all, it makes possible for more convenient and secure home. It has to be developed along with city and town level changes as ubiquitous environment. Secondly, concept of extended space as an extension of living space becomes possible by linking with outside spaces. Thirdly, as consumer requirements for residential spaces will become more versatile by social changes, ubiquitous home can be a good means to meet these versatile consumer requirements by accommodating concept of multi-functional space and flexible space. It is quite important to predict user requirements in rapidly changing social environment and versatile personal inclinations. Instead of POE methodology which can analyze and evaluate in exiting types of designs, storytelling methodology can be used to predict and direct for future requirements of living. The methodology makes scenarios of space usage for future living and extracts design requirements for the living. The concept of intelligent space has to be introduced. It is different from digital home that only accomodate digital devices in space. In intelligent space, space itself has to be recognized as an identity that interacts human directly. Intelligent space recognize human requirements and control digital devices as a response. Multi-functional space is closely related with intelligent space that can changes for business, entertainments as well as for rests by user requirements instantly. Flexible space that also intends to meet requirements of mobility and versatility can be attained through the integration of digital technology into current physical mobile systems. Interaction design becomes integral part for ubiquitous space design along with physical design. For the residential space design, digital illiteracy has to be considered for interaction design. Instead of the concept of passive existence, space itself has to be recognized as active subsistence that reacts with human. Intuitive and natural interaction for human will be a key design element for space-human interface design.
