Recommender systems have been widely advocated as a way of coping with the problem of information overload in e-business environment. Most of the existing recommender systems focused on what kind of items to recommend, although when to recommend to the target customer considering their context is an important issue. Even right item might be a spam advertisement or wrong recommendation for the customer if it can not be recommended at the right context. It is particularly important for recommendations where the user's context is changing rapidly, such as in both handheld and ubiquitous computing environment. Therefore, we propose CARS (Context-Aware Recommender System) based on CBR and context-awareness for ubiquitous computing environment. CBR is used to generate a target customer class and proper context. Context-awareness is used to gather suer context information from sensors, networks, device status, user profiles, and other sources. An illustrative case example is suggested to explain the procedure of CARS.

This study is intended to forecast changes in Ubiquitous technology-based residential environment since the digital revolution so as to suggest the direction of furniture design in the near future. Among Ubiquitous technologies, the intelligent digital technology applied to a residential environment is defined as "Smart Digital Technology." Ministry of Commerce, Industry and Energy named the residential environment where such technology is applied "Smart Home." Smart Home is strategically creating intelligent residential environment where interactivity is made between human, furniture and residential environment, based on home automation, home network and intelligent sensor technology. Smart furniture is based on strategic characteristics of smart home. Its convergence with IT equipments is being made. Largely, smart furniture has three characteristics as below: First, smart furniture provides users with information on home management, health management, education and fashion. not just functioning as storage space. Second, smart furniture that is a new lifestyle pattern will suggest a new aesthetic standard based on unsettled shapes and innovative structure. Finally, it gives convenience to users intelligently. Namely, smart furniture, "intelligent informative furniture", will be suggested as a new paradigm.

Since ubiquitous embedded software is sensitive to the resources and environment of target system, it should be debugged in the same environment as actual target system. However, existing tools to debug embedded software, in which access to internal signal or resources is limited, are uneconomical. In the thesis, economical and practical USB-JTAG Adapter that can use open GDB is suggested. It can remove existing limitations of environment implementation that have many difficulties in implementing an environment for remote debugging. Hence, the thesis provides economical interfacing environment that can debug ubiquitous embedded software inside remote system.

유비쿼터스 시대와 더불어 미용학의 헤어분야도 발전하고 있다. 본 논문에서는 유비쿼터스 네트워크에서 디지털 헤어 체인징을 설계하고 구현한다. 미용사가 시술하기 위해 디지털 카메라를 이용하여 고객의 얼굴 모습을 촬영한다. 인터넷에 접속하여 고객의 얼굴과 헤어가 모니터에 나타나면, 웹 서버에서 보유한 커트, 퍼머, 업스타일, 염색, 긴 머리 등의 디지털 콘텐츠를 이용하여 이동단말기에서 고객의 헤어모습에 대한 선택과 호응을 얻는다. 미용사는 이동단말기의 헤어 디자인 이미지를 보면서 고객의 헤어를 시술 한 후, 다시 디지털 카메라로 찍어 웹 서버에 자료를 업 데이트 한다. 고객은 이 사진을 자신의 이동단말기에 저장한다. 유비쿼터스 네트워크에서 이를 적용하기 위한 유비쿼터스 헤어 체인징 시스템을 설계하고, 디지털 헤어 콘텐츠와 온라인 인터넷 시스템 및 이동단말을 통한 시스템을 구현하여 미용 정보사회 발전에 기여하고자 한다.

As the ubiquitous computing technology (uT) is prevailing, applying uT is more likely to transform the legacy way of doing business to a new way with the goals of ubiquitous computing: strategic use of information resources by using them everywhere, every time, with any devices for any services. These opportunities naturally require the provision to assess the degree of the transformation from the legacy IT-based e-business to the uT-based business. However, research about assessing the degree of u-transformation has been still very few. Moreover, even deciding what is ubiquitous or not is obscure. Hence, this paper aims to propose the methodology for assessing the degree of u-transformation oriented by the teleology of ubiquitous service, which intends to fully make use of uT in creating new business of next generation. Through the literature review, we developed the methodology to check whether the provided service is ubiquitous or not based on the capabilities that technologies have. and then, the methodology developed to assess the technical requirements that the uT should have when the transformation is considered through the focus group interview based on the literature review of the capability. A two-layered approach is introduced to assess not only the level of ubiquity but also the degree of u-transformation.

Fruition for a diverse uIT(Ubiquitous Information Technology) service is currently required through the convergence of what is known as ubiquitous computing technology. In recent years, with the rapid growth of the need for information services, heavier demands have been made upon the supply of high-quality multimedia services that require a high bandwidth. Today, various home network solutions have been proposed to manage these service smoothly and a system able to deal with various types of network traffic without delays. In addition, in established home network environments that mix wired and wireless networks, along with the steady evolution of wireless network technology and the earnest development of ubiquitous computing technology, sensor-based wireless networks have emerged as a core solution for home networks. In this paper, a sensor network-based home control system supporting the next generation home gateway system for ubiquitous home environments is designed and implemented.

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.

Ubiquitous sensor network is to manage and collect information autonomously by communicating user around device. Security requirements in Ubiquitous based on sensor network are as follows: a location of sensor, a restriction of performance by low electric power, communication by broadcasting, etc. We propose new mutual authentication protocol using a low power of sensor node. This protocol solved a low power problem by reducing calculation overload of sensor node using two steps, RM(Register Manager) and AM(Authentication Manager). Many operations performing the sensor node itself have a big overload in low power node. Our protocol reduces the operation number from sensor node. Also it is mutual authentication protocol in Ubiquitous network, which satisfies mutual authentication, session key establishment, user and device authentication, MITM attack, confidentiality, integrity, and is safe the security enemy with solving low electric power problem.
