  • When we are visiting unfamiliar huge public places, it is hard to know what, how, and where to go. For solving these problems, we have suggest a user guide system, and a knowledge model which is built to support the system. High intelligence guidance system needs to react the user's context more spontaneously, which could be obtained when a system aware both the location and process coordinately. In this paper, we will show how our knowledge model is designed to enable the system to interpret simultaneously both of them.

  • The objectives of this study are (1) to review previous studies in the context of brand management in consumer behaviors using costumer based brand equity (CBBE) and theory of planned behavior (TPB) as the basic foundation of the study; and (2) to develop a comprehensive research model by integrating relevant research constructs using meta-analysis. This study reviewed a total 173 studies from 58 published papers with 40 journals during 1991~2014 and developed a comprehensive framework with 16 research hypotheses. The results showed that (1) brand image, brand personality, brand association, and subjective norm are the important antecedents of brand attitudes; (2) brand awareness, brand trust, perceived quality, and perceived behavioral control are the important antecedents of brand loyalty; (3) brand attitude positively influences brand loyalty, which further influences brand equity; and (4) brand equity positively influences behavioral intention. This study fills in the research gap by integrating more research variables into CBBE model, particularly to include the influence of social context on consumer behavior through TPB. These results indicated that the integration between CBBE and TPB is meaningful and the comprehensive model can explain more variances than that of the individual model. Limitations, and recommendations for future research in this area are provided.

  • An URC (Ubiquitous Robot Companion) is aimed for providing the best service according to situational information that it recognizes. In order to offer human-friendly and intelligent services, a robot middleware requires the technique to automate and control URC service processes, which are based on context-awareness. In this paper, we propose a context-aware workflow system to provide web services based URC services according to situational information. The proposed system offers a platform-independent command object model to control heterogeneous URCs, and supports web services based context-aware URC services. Therefore, the proposed system can increase the reliability of URC services in ubiquitous network environment, on which the diverse URC robots and platforms exist. And it can enhance the flexibility and adaptability of the functional and structural changes of URC systems.

  • When unapproved users access to healthcare system and use medical information for other malicious purposes, it could severely threaten important information related to patients' life, because in ubiquitous environment healthcare service makes patient's various examination results, medical records or most information of a patient into data. Therefore, to solve these problems, we design RBAC(Role Based Access Control) for U-healthcare that can access control with location, time and context-awareness information like status information of user and protect patient's privacy. With implementation of the proposed model, we verify effectiveness of the access control model for healthcare in ubiquitous environment.

  • Aiming at solving the problems associated with existing wireless paging systems, this paper proposed a 4W1H+L+PI concept to context-aware information structure, based on which, a new wireless paging system named 119 system is developed under ubiquitous environment. Bemuse of the adoption of RFID tags in the wireless paging system, hazard and malfunction rates are reduced, thus accuracy is guaranteed. Besides, response time is shortened comparing with existing systems. In the future, if emergency aid information system can be implemented under the ubiquitous computing environment combined with sensor network, then aid service of good quality will be provided.

  • 스마트 폰을 비롯한 다양한 모바일 기기는 사용자 중심의 정보 수집과 상황 인지 및 서비스 제공에 적합한 환경이다. 하지만 사용자에게 의미 있는 서비스를 제공하기 위해서는 단순한 환경 상태 또는 행동에 대한 추론보다는 사용자의 행동에 대한 목적과 의도를 파악할 수 있어야 한다. 즉, 주변 환경 상태와 사용자의 행동 이력, 현재의 행동 등을 종합하여 사용자가 필요로 하는 서비스를 예측하고 결정할 수 있는 상황 모델이 필요하다. 따라서 본 논문에서는 사용자의 일상 생활 상에서의 중요한 일정을 추적하여 적합한 모바일 서비스를 제공하기 위한 기반 지식 모델로서 계층적인 모바일 컨텍스트 모델을 제안하고자 한다. 기존의 상-하위 컨텍스트 모델을 세분화하고 의미 있는 컨텍스트를 추가하여 서비스를 결정하는데 중요한 기반 정보로 활용될 수 있도록 한다.

  • This paper implemented the u-Healthcare Context Information System (HCIS) supporting ubiquitous healthcare by using location, health and titrating environment information collected from sensors/devices equipped in home for healthcare home service. The HCIS is based on the Distributed Object Group Framework (DOGF), a management model which can customize distributed resources, and manages various context information, applications and devices as a group in healthcare home environment, as one more logical units. Also, this system provides continuous healthcare multimedia service considering a resident's location using Mobile Proxy, and the healthcare context information through Context Provider to a resident in home. For verifying execution of our system, we implemented the seamless multimedia service based on resident's location and the prescription/advice and schedule notification/alarm service as healthcare applications in home. And we showed the executing results of healthcare home service by using service device existed in the residential space on which the resident is located according to the healthcare scenario.

  • We proposed the context based user profile which is aware of its user's situation and based on user's situation it recommends personalized services. The user profile which consists of (context, service) pair can be acquired by the context and the service usage of a user; it then can be used to recommend personalized services for the user. In this paper, we show how they can be evolved without previously known user information so that not to violate privacy during the learning phase; in the result our user profile can be applied to any new environment without any modification to model only except context profiles. Using context-awareness based user profile, the service usage pattern of a user can be learned by the union of contexts and the preferred services can be recommended by the current environments. Finally, we evaluate the precision of proposed approach using simulation with data sets of UCI depository and Weka tool-kit.

  • The present study proposes a model for literature-based instruction within the context of a fashion design curriculum at a Korean university. The fashion design market continues to grow. The fashion design market now requires more cultural-bound strategies and efficient communication skills. The literature provides authentic resources and is highly relevant to the development of students' culture awareness as well as language awareness. Alice's Adventures in Wonderland written by Lewis Carroll contains various cultural contexts of the Victorian Era. The text provides explicit knowledge of the era depicted in both illustrations and satire languages. This study instructs students to analyze and interpret texts and illustrations so that they can engage critically and analytically in reading text to increase culture awareness and language awareness. The integration of literature and fashion design can provide students an opportunity to explore language choice and acquire refined knowledge of the target culture. Along with the text, illustrations in the literature provoke student's imaginative and creative thinking skills. Students can think and discuss many issues that deal with Victorian values and reinforce creative thinking skills. In the final stage, students can design fashion inspired by Victorian values and present their own designs using the acquired languages. This eventually leads students to adapt to a new notion for the fashion market and become competent communicators in the fashion world.
