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.

This study is aimed at proposing a new approach to designing UDSS (Ubiquitous Decision Support System) which allows context-awareness and connectivity. In the previous studies, the need to design UDSS and analyze its performance empirically was raised. However, due to the complexity of empirical approaches, there is no study attempting to tackle this research issue so far. To fill this research void, this study proposes a Mobile Delivery System (MDS) as a form of UDSS, empirically analyzing how users perceive its context-awareness and connectivity functions. Especially, to add more rigor to the proposed approach to know how much it works well in the decision-making contexts, we considered three decision making phases (intelligence, design, choice) in the research model. With the valid questionnaires collected from 340 users of the MDS, we induced statistically proven results showing that both context-awareness and connectivity of the proposed UDSS (or MDS) influence the decision making steps positively and then contribute to improving the decision making quality.

모바일 정보통신 사용자들에게 있어서 모바일 상거래는 기존에 존재하던 정보에 대한 통신 및 네트워크 접속 등 이용상의 제약을 뛰어넘어 정보이용의 활성화에 있어 주요한 전환점을 가져오고 있다. 모바일과 같은 정보통신기술의 발달로 금융정보화 투자가 촉진되어 금융중개기관의 경영전략 사무합리화 업무효율화 및 고객과의 관계 등과 같은 부분에서 여러 가지 변화가 일어나게 되었다. 금융산업계에서는 고객들의 금융 서비스 욕구가 다양해지고, 고객 중심의 금융시장으로의 전이로 인해 고객을 최우선으로 하고 고객과의 관계를 효과적으로 구축하기 위한 경쟁이 치열하다. 그 노력의 일환으로 IT기술을 활용한 CRM(Customer Relationship Management)을 금융산업의 중요한 전략 중 하나로 추진하고 있다. 하지만, 모바일 환경을 고려한 CRM 성공요소들이 CRM 성과에 미치는 영향에 대한 연구는 여전히 부족한 편이다. 따라서 본 연구의 주목적은 모바일 기술의 대표적 특성인 이동성과 편재성이 CRM 성공요소(최고경영자지원, 고객지향 조직문화, 부서간 상호작용, 고객정보 통합성)와 CRM 성과 사이에서 어떤 영향을 미치는지에 대해 실증적으로 규명하고자 하는데 그 목적이 있다.

This paper discusses a skeleton feature extraction method for ubiquitous robot system. The skeleton features are used to analyze human motion and pose estimation. In different conventional feature extraction environment, the ubiquitous robot system requires more robust feature extraction method because it has internal vibration and low image quality. The new hybrid silhouette extraction method and adaptive skeleton model are proposed to overcome this constrained environment. The skin color is used to extract more sophisticated feature points. Finally, the experimental results show the superiority of the proposed method.

Ubiquitous society education students, teachers, parents, and educational administration systems, learning tools, and things connected to this one because it provides a learning environment in education for each student to determine their characteristics and needs, and even provide the required services for each student can. In other words, students and teachers within the school to concentrate on education and research activities of the intelligence service is the latest. The future of the ubiquitous era of ubiquitous era of education the future of the education side of the current lack of education to complement the new era of human resources required to foster a positive alternative to bear fruit for all members of our community's interest and commitment, wisdom and education officials, This will be together.

Effective energy consumption now becomes one of the area of knowledge management which potentially gives global impact. It is considerable for the energy management to optimize the usage of energy, rather than decreasing energy consumption at any cases. To resolve these challenges, an intelligent and personalized system which helps the individuals control their own behaviors in an optimal and timely manner is needed. So far, however, since the legacy energy management systems are nation-wide or organizational, individual-level energy management is nearly impossible. Moreover, most estimating methods of energy consumption are based on forecasting techniques which tend to risky or analysis models which may not be provided in a timely manner. Hence, the purpose of this paper is to propose a novel individual-level energy management system which aims to realize timely and personalized energy management based on context-aware computing approach. To do so, an index model for energy consumption is proposed with a corresponding service framework.

In this paper, It proposes that solar cell monitoring system using ubiquitous technique, solar cells development system occurs the attrition at the same time in several segments. This is the reason why, whole damage is also looked greatly increased inclination. Therefore, we progress study that find out damage factor by element and are more deeply about loss reduction by element part hereafter. Also, efficiency of solar photovoltaics system can be improved. we wish to forecast efficiency decrease of solar photovoltaics using neural network algorithm. Experiment result hereafter, We will expect to be remote management of solar cell.

컨테이너터미널의 Gate는 컨테이너의 출입구를 의미하는 것 외에 컨테이너 정보의 최초 입력점이라는 중요한 의미를 가지고 있다. 따라서 컨테이너 정보의 정확한 습득을 위해 다양한 컨테이너 변호 인식방법이 사용되고 있으며, 이러한 적용방법에 따라 Gate의 생산성에도 많은 차이가 발생하고 있다. 최근, 정부의 u-IT사업추진에 따라 적용되기 시작한 RFID를 이용한 Gate자동화 방식은 기존시스템에 대한 새로운 접근을 요구하게 되었다. RFID를 이용함에 따라 각 시스템의 단점을 보완하는 정성적 이점과 더불어 정량적 생산성 향상이라는 기대치도 높아지게 되었다. 따라서 본 연구에서는 RFID를 이용한 Gate 자동화 시스템과 기존의 Gate시스템과의 생산성 차이를 시뮬레이션을 통해 검증함으로써 RFID 방식의 Gate를 고려하고 있는 컨테이너터미널에 관련된 정보를 제공하고자 하였다.
