The objective of this paper is to identify factors influencing intention to use ubiquitous banking service focusing on potential users using a regression model. Through this, providers of ubiquitous banking services can get an idea of future development, including marketing strategy through the results of this analysis. This paper proposes that perceived usefulness is the most important factor influencing the uptake of ubiquitous service. Also in addition, ANOVA test shows that higher education level of the user can lead to the higher intention to use an ubiquitous banking service. In this study, we set up a model by using the most basic factor among influential factors presented in previous studies as an independent variable. However, other research variables which affect acceptance of ubiquitous service should be considered by thinking more diversely.

최근 새로운 정보기술 패러다임인 유비쿼터스가 등장함에 따라 그에 관련된 연구와 개발이 활발해지고 있다. 유비쿼터스 환경에서 기업은 효과적인 상품 개발과 서비스를 위해 사용자들이 어떠한 요인에 의해 u-서비스를 이용하는지에 대한 연구가 필요하다. 그러나 유비쿼터스에 대한 기존 연구는 기술 중심적인 연구에 치중되어 서비스나 상품을 마케팅 하는 데는 시사점이 적었다. 본 연구에서는 u-서비스 이용에 영향을 미치는 중요 요인에 대한 실증적 연구를 통해 기업의 입장에서 향후 u-서비스를 개발하고 이용자를 확대하는데 시사점을 제공하고자 하였다. 본 논문은 기존 문헌을 바탕으로 유비쿼터스 개념을 정의하고 유비쿼터스 특성요인을 반영한 u-서비스 수용 모델을 제시하고 이를 실증하였다. 그 결과 u-서비스 이용에 영향을 미치는 요인은 편재성, 상황기반 제공성, 친화성 등이었으며 지각된 가치는 이용의도에 영향을 미치며, 또한 이용 빈도에도 유의한 영향을 미치는 것으로 나타났다. 이러한 실증결과를 바탕으로 u-서비스 활성화를 위한 마케팅적 시사점을 토의하고, 연구의 한계점과 향후 연구방향을 제시하였다.

Various kind of ubiquitous healthcare services have been developed and tried in patient care and health care fields. Due to technical restrictions and not enough application practices, the service systems have been developed somewhat in ad hoc way. This paper describes the requirements for ubiquitous healthcare service systems most of which need to have and presents a ubiquitous healthcare service system architecture with which various ubiquitous healthcare services can be developed. It also introduces an application system for ubiquitous benign prostatic hyperplasia (BPH) patient care which has been developed based on the architecture.

The evaluation of ubiquitous computing service is the important work for preparing the commercialization of the ubiquitous business services in which ubiquitous intelligence (ubitelligence) is embedded. However, the methodology for evaluating ubiquitous computing services has not been developed enough. Even the study of making a distinction what is 'ubiquitous' or not is insufficient yet. Hence, this paper aims to propose an integrated methodology to assess the ubiquitous computing services. A multi-layered approach is adopted to assess not only technical but also behavioral service levels.

Recently, the korean statistical information service reported that the elder people aged over 65 years take 11 percentage point of all population, indicating that the hyper-elder era will advent shortly. As a result, there are remarkably increasing demands for providing self-organizable home agent system for elder people. Of the home agent system, the ubiquitous home service is known to be useful to overcome this problem. However, current ubiquitous home services limited to provide functional services, and it can be observed that there is lack of consideration for elder-support products which are closely interacted with elder people in the living situation. In this paper, we analyze senior aids products that can be combined to the ubiquitous home service, and propose design procedure for senior aids products that can be applied to self-organizable ubiquitous services. We studied characteristics of elder people, current state of affairs for senior aids products, and home services that are highly required by elder people. Moreover, we observed that the ubiquitous home services related to health, safety, and amenity are urgently needed, and those services can be categorized according to residential areas. Following those observances, we proposed a design principle based on the universal design paradigm to provide self-organizable ubiquitous home service environment for elder people using senior aids products.

정보기술의 혁신은 오늘날 정부의 개혁 노력에 있어서 매우 결정적인 역할을 하고 있으며, 전자정부는 그 대표적인 예라고 할 수 있다. 그러나 전자정부 서비스 제공의 문제점은 무엇보다도 도민들의 활용도가 저조하다는 것이다 전자 정부가 실제 수요자인 도민에게 대응적 서비스를 제공되지 못하였기 때문이다. 이에 경상남도는 향후 유비쿼터스 서비스를 제공하는데 있어서 무엇보다도 도민의 수요에 대응적인 서비스 방안이 모색하여야 할 필요성이 있다. 본 논문은 경상남도 도민을 대상으로 유비쿼터스 서비스에 대한 인식 조사를 실시하여 현황 파악 및 연관성 규칙을 분석한다. 본 논문의 결과는 경상남도의 유비쿼터스 서비스 구축에 대한 정책적 기초 자료를 제공할 수 있다.

Ubiquitous computing is enhancing computer use by making many computers available throughout the physical environment without being noticed to the users. To facilitate successful adoption and diffusion of ubiquitous systems, it is important to find out the factors affecting their uses. Although researches related to ubiquitous computing have been vigorously conducted from the aspect of system and service provider, there have been very few studies that focus on the user's perspective. This study attempts to find out major factors which are dedicated to the development of ubiquitous systems and services and the relationships between these factors and user satisfaction factors. This study derived the specific factors that characterize ubiquitous services, such as ubiquity, contextual offer, user affinity, privacy, reliability, responsiveness, assurance, and empathy. We also considered service quality factors of ubiquitous services. Then these factors were combined with the Expectation Confirmation Theory (ECT) model and the path analysis was applied to find out the factors affecting user satisfaction and the intention to use the systems. The research findings indicate that ubiquity, contextual offer, privacy, reliability, and responsiveness affect the perceived usefulness. The perceived ease of use and confirmation were found to affect the perceived usefulness. The perceived usefulness, perceived ease of use, and confirmation fumed out to influence the satisfaction. It turned out that the result of this study on the relationship between the perceived usefulness and user satisfaction was identical with the findings in previous related ECT researches. We think this study makes two significant contributions to the development of ubiquitous services. First, this study provides basic implications for better ubiquitous services by considering important characteristics of ubiquitous systems as services. Second, this study also suggests important factors that need to be considered when ubiquitous service providers develop new ubiquitous services to improve user satisfaction and the intention to use the services.

현재 우리는 Ubiquitous IT기술을 활용한 편의시설이 곳곳에 적용되어 가고 있는 도시에 서 살아가고 있으며, 이러한 Ubiquitous IT기술은 발전에 발전을 거듭하여 우리가 느끼지 못하는 곳까지 확대되어 가고 있다. IT산업과 도시산업의 융·복합화을 통해 형성되는 새로운 도시의 개념인 u-City는 다양한 u-Service의 제공을 통해 국민의 삶을 향상시키는데 의의가 있다. 정부에서도 Ubiquitous 활성화 정책과 u-City 관련 산업 육성을 위해 노력하고 있으며, 이에 Ubiquitous 환경 및 정보인프라 구축등 기술적 구현은 빠르게 발전되고 있다. 그러나 u-Service의 효과를 체험하고 보다나은 서비스가 제공될 수 있도록 정보를 제공해 주어야 하는 소비자(국민)들은 계층별 정보격차로 인해 체감할 수 있는 u-Service가 미흡한 것으로 파악된다. 따라서 본 논문에서는 정보격차 분석을 통해 계층별 소비자 맞춤형 u-Service 적용방안을 제시하고자 한다. 이에 본 논문은 u-Service의 기본단위인 도시에서 생겨나는 정보격차 속성을 이해하고, 정보격차의 주체별 분석을 통하여 올바른 u-Service를 적용할 수 있는 효율적인 방안을 제시하고자 한다.

In this paper, we defined constructivism and ontology theory and associate it in ubiquitous learning. The typical ubiquitous learning involving the Context Aware Intelligent system was presented. Also the Architecture for learning environment including the key idea and technical concept is being presented in this paper. Guided with these principles and with the advancement of information and communication technology the context-awareness based on Artificial intelligence for Location based Service for ubiquitous Learning was conceptualized.

The purpose of this study is to introduce ubiquitous home services for the aged. In comparison with general ubiquitous homes, ubiquitous homes for the aged have two major characteristics. First, the service contents should be expanded and strengthened. Second, the services should be customized to each individuals. The primary objective of a ubiquitous home for the aged is health care. The three affordances for this objective are 1)prevention of sickness and reducing the speed of aging process, 2)technical assistance for disability, 3)recovering and enhancing the physical and cognitive function. For this purpose this paper analyses the characteristics of the aged and current ubiquitous technology and ubiquitous home service, thus providing an outline for ubiquitous services necessary for aged people.
