삶의 질을 향상시키기 위한 유비쿼터스 테크놀로지 도입으로 인해 제품개발, 주거, 상업시설 등에서 시작하여 최근 유비쿼터스 환경 구축의 일환으로 u-City 구현에 중점을 두고 많은 연구 진행되고 있다. 그 중 가로환경 디자인은 공공 시설로서 유비쿼터스 환경 구축의 중요한 이슈가 되고 있다. 그러나, 오늘날 가로 공간은 그 수가 양적으로 팽창되었을 뿐 각각의 특색에 맞게 조성되고 있지는 못하며, 물리적 환경개선에 중점을 두어 단순한 가로정비 수준에 머물고 있다. 이로 인해 지역주민과 이용자 중심의 참여에는 부족한 면이 많았다. 이에 본 연구는 유비쿼터스 테크놀로지를 도입하여 보다 실용적이고 현실 참여적인 공간으로 디자인함으로써 새로운 u-Street 디자인을 제안하고자 한다. 또한, 이와 같은 공공장소에서의 서비스가 이용자들과 어떠한 인터렉티브 커뮤니케이션을 가질 수 있을지에 대해 살펴보고 이를 디자인에 반영하여 공간이 인간과의 상호작용을 원활히 하고 감성적인 공간 디자인이 될 수 있도록 u-Service 를 개발하는 데 중점을 두고자 한다. 본 연구는 부산 광복로를 사례로 진행되었으며, 그 결과 다음과 같은 측면에서 기대효과를 예측할 수 있다. 첫째, u-City 의 기반 시설로서의 u-Street는 수평적이고 친환경적인 가로 경험을 통해 사람이 직접 여러 서비스와 인터렉션할 수 있다. 둘째, 본 연구에 제안된 u-Service 는 이전 광복로의 침체되고 비활동적인 공간을 활동적이고 생동감있는 공간으로 재활성화시키는데 중요한 매개체로서의 역할을 하게 될 것이다. 셋째, 주민과 이용자들의 적극적인 참여를 유도하여 지속적인 공간을 만들어 내는 데 크게 기여할 것이다.

Event driven service (EDS) is one of such services administrating different functions of multiple service providers according to the user situation. This paper first describes the service model of EDS, a User-centric Service for multiple service provider environments over the next generation networks. The multiple provider environments stimulates the unified identifier management, namely unified identification (U-ID), to enable users to be provided network services without awareness of multiple providers. Combining these two concepts, i.e., EDS and U-ID, the designed structure of EDS with U-ID and related procedures are given. Finally, the implementation results tested on Korea Advanced Research Network (KOREN) are described.

For digital TV, the recommendation of u-health personalized service of semantic environment should be done after evaluating individual physical condition, illness and health condition. The existing recommendation method of u-health personalized service of semantic environment had low user satisfaction because its recommendation was dependent on ontology for analyzing significance. We propose the personalized service recommendation method based on Naive Bayesian Classifier for u-health service of semantic environment in digital TV. In accordance with the proposed method, the condition data is inferred by using ontology, and the transaction is saved. By applying naive bayesian classifier that uses preference information, the service is provided after inferring based on user preference information and transaction formed from ontology. The service inferred based on naive bayesian classifier shows higher precision and recall ratio of the contents recommendation rather than the existing method.

For real-time social networking service, mobile interaction in a usable-unified-ubiquitous (U3) web service was studied. Both as a convenient mobile HCI for real-time social networks and as indexing keys to metadata information in ubiquitous web service, the multi-lingual single-character domain names (e.g. 김.net, 이.net, 가.net, ㄱ.net, ㄴ.net, ㅎ.net, ㅏ.net, ㅔ.net, ㄱ.com, ㅎ.com) are convenient mobile interfaces when searching for social information and registering information. We introduce the sketched design goals and experience of mobile interaction in Korea, Japan and China, with the implementation of real-time social networking service as an example of U3 Web service. We also introduce the possibility of extending the application to the metadata directory service in IP-USN (IP-based Ubiquitous Sensor Network) for a unified information management in the service of social networking and sensor networking.

As a comparative study on the value of design concept between service provider (Developer) and service receiver (Customer) group, the aims of this study was to present a service model focused on Continuous positive airway pressure (CPAP) based on U-health care and user environment. Double Diamond-based methods led to a case study that conducted jointly by the department of otolaryngology in U hospital, Ulsan. By targeted on Sleep Apnea patients from the stage of diagnosis to CPAP treatment, variety of meaningful experiences have been extracted and classified into several types of customers. In the final analysis of the 13 service scenario models, Kano Satisfaction and Potential Customer Satisfaction Improvement Index (PCSI) were conducted with the customers, yet Score Model and Concept Position were evaluated by the service provider groups who engaged in development services. The results of this study showed that 7 items in the total of 12 items reached a consensus of viewpoint on value between service receiver and service provider, which the attributes of the service model are based on user environment. Whereas the other 5 items showed the divergent viewpoint on value which included the attributes of U-healthcare service model.

Ubiquitous city which was appeared since 2006 is defined as "The city provided the ubiquitous city service anytime and anywhere using ubiquitous urban infrastructure to improve the city's competitiveness and quality of life" under ubiquitous city construction law. To realize the ubiquitous city, the city has to be constructed efficiently based on the spatial information. And connection of information achieve effective synergy. In this study, applied multilateral analysis to spatial information and administrative information to implement u-service focused on MACCA(Multifunctional Administrative City Construction Agency). Study about main function and product data with connection process of Korean Land Spatialization System and administrative information System was performed. Also, details of u-service and method of acquiring necessary data were derived. In Addition, the information connection possibility for efficient u-service realization was suggested by linkage analysis method to utilize the related information infrastructure jointly.

Developing various ubiquitous computing services (U-services) is being propelled throughout the industry. As U-services are being penetrated into our daily life, research on the factors influencing the acceptance of U-services is highly needed. In this line of study, we examined previous literatures about information technology acceptance and UTAUT model, and applied UTAUT model to U-service acceptance. To characterize the U-services into our research model, we newly introduced 'context based personalization' factor. Since the respondents could not directly experience the U-services yet, we adopted scenario-based questionnaire. For this, we deliberately developed U-service scenario. And then this U-service scenario is verified using capability-based assessment method. Using data collected from 251 respondents, this study found that 'context based personalization' factor was positively and significantly related to the acceptance of U-service as well as UTAUT model's 4 factors such as performance expectancy, effort expectancy, social influence and facilitating conditions.
