The purpose of this study is to suggest configuration methods of sensor according to user's behaviors in the ubiquitous house. Recently, with appearing the concept of 'Ubiquitous', the applications of ubiquitous technologies on the our environment adopt a new paradigm. This new paradigm leads to the possibility of creating more intellectual dwelling environment according to user's behaviors. This paper suggests to change our dwelling by considering both engineering technology and considering the character of dwelling, because the house should provide causes humans with comfortability. Therefore, we need to understand user's behaviors in the dwelling, towards user friendly environment.

In this paper, we study to two research direction about information security in ubiquitous computing environment. First, researches on context-aware access control using user's context or environment conditions based on role-based control. Second, researches on model for access control about context information in ubiquitous computing utilizing role base access control model. Two research directions are the one of the most important point technology in that embody ubiquitous environment in the actual world.

The library space has historically been influenced by the change of its information and social environment. This paper describes the effect of ubiquitous environment on the library's space, by literature review, case analysis. and focus-group interview of 5 undergraduate students. The results show that the library's physical place is still important for users, and suggest the library information space design and management need to reflect the open-ness and the interactive-ness of the ubiquitous space.

유비쿼터스 시스템을 개발하기 위해서는 여러 전문 분야를 포괄하는 복합적 지식과 가상적 접근이 요구된다. 본 논문에서는 이러한 요구를 만족시키기 위해 CAUSE(Computer-Aided Ubiquitous System Engineering)를 제안한다. CAUSE는 유비쿼터스 시스템 자체를 하나의 컴퓨터 지원 도구를 사용하여 개발하는 것으로 유비쿼터스 시스템 엔지니어가 복합적 관점에서 시스템을 개발할 수 있도록 해준다. 논문에서는 우선 CAUSE의 아키텍처를 제안하고 그것을 유비쿼터스 기숙사에 적용한 CAUSE for Ubiquitous Dormitory 개발에 대해 소개한다.

The purpose of this study is to improve ubiquitous fashion design which adolescents can be satisfied with. The methods of this study are documentary research of previous studies, survey research and deep interviews. For this study 371 students are selected as samples of survey. As a result of this study, we could know that the adolescents of the 21st century are enjoying actively the culture of consumers and the culture of information era. Domestic adolescents have much knowledge and interest in information and in UFC fashion products. So we can predict that domestic adolescents' interest and desire of UFC fashion products will increase gradually. As for using occasions, adolescents will use UFC fashion products for 'mobile', 'exercise', 'social followship', and as for using purposes, they will use UFC fashion products for 'listening to music', 'playing games', 'communication', 'search for information', etc. So when we develop UFC fashion products for adolescents, we'd rather develop the products for entertainment than for studying. To satisfy the various tastes of adolescents, UFC fashion products must also consider the design factors like styles, colors, materials, etc. In conclusion all UFC fashion products for adolescents must have not only the basic qualities like functions and conveniences, but also the qualities of designs.

This paper proposes and analyzes the anti-collision algorithm in Ubiquitous ID system. We mathematically compares the performance of the proposed algorithm with that of binary search algorithm, slotted binary tree algorithm using time slot, and bit-by-bit binary tree algorithm proposed by Auto-ID center. We also validated analytic results using OPNET simulation. Based on the analytic results, comparing the proposed algorithm with bit-by-bit algorithm which is the best of existing algorithms, the performance of proposed algorithm is about 5% higher when the number of tags is 20, and 100% higher when the number of tags is 200.

In ubiquitous computing environments, users want to receive the robot services regardless of various physical status or devices such as time, place, various sensors, and high-performance servers. Thus, the ubiquitous service robots have to provide users with automated services according to situational information that they properly recognize. Beyond these problems, robot software has to establish a foundation to support the functions with the network infrastructure that are not able to be solved by a single independent resource. On the basis of a robot middleware that is capable of minimizing dependencies among hierarchy structures, the robot software also has to provide execution environment to control the flow of robot application services. In this paper, we propose a layered architecture to provide users with automated services through ubiquitous robots. The proposed architecture is based on CAWL (Context-Aware Workflow Language) and RSEL (Robot Services Execution Language). CAWL easily represents the flow of robot services from user application service levels, and RSEL is able to support the composition and reusability of robot services through abstraction of robot device services. In our experiments, we applied the proposed architecture to an example of "booth guide robot service".

The purpose of the study was to examine the implications for new strategical policy on promoting lifelong learning in ubiquitous society by gathering the views and ideas of experts. We interviewed with 15 experts in the fields of ubiquitous learning and technology. In the result, we found the following pre-requisites in promoting lifelong learning in ubiquitous society: 1) consensus regarding the ubiquitous society, 2) infra structure and various services, 3) contents based on the citizens' needs, 4) information gap closing, and 5) law and institutions in terms of lifelong learning in ubiquitous society.

The exhibition and convention industry offers facilities and services required to host expositions and conferences. Currently, it has been greatly esteemed as a promising industry because it can produce a higher added value and maintain a pure environment at the same time as an aggregate of service industries. Like other industries, the need of digitalization and information system in the exhibition and convention industry makes it introduce ERP and MIS and nowadays ubiquitous related model projects are ongoing. In this paper, we conduct researches regarding the systematic introduction of ubiquitous related technologies through the service and information system identification of exhibition and convention industry, and analysis of value chain and critical success factor. We consider RFID, ZigBee and mobile related technologies as the ubiquitous related technology types and select the exhibition witness and the maintenance of facilities as the area of related technologies introduction. In addition, we propose a scheme used to analyze and solve the problems which could be occurred when ubiquitous related technologies are applied. The results of this paper could be used as a policy to nourish exhibition and convention industry, and a guideline of the host organizations.

With the introduction of the ubiquitous technology, the housing culture centers have demonstrated future housing image or technology. But Ubiquitous Home Services in the future housing were more focused on implementation of environment for the future than exhibition that consumers can experience. The purpose of this study was to identify ubiquitous home services which were realized in domestic future housing and to compare those with results of previous researches on demand for u-services. For this study, field study was conducted with 3 domestic future housings and 14 previous studies on demand of u-services were analyzed by the standard of residents demand. The results of the study showed that u-services for housework and leisure life more than those for security and health, were applied in the future housing. However, residents prefered u-services for security and control of indoor environment to those for housework and leisure life. As a result, it was found thatu-services which residents needed mainly were discordant with those that were displayed frequently in future housing. Also developing u-services reflected the needs of residents, a test bed has to be established in the future housing and then pre-evaluaiton can be conducted.
