Nowadays great changes arises from the digital environment and technology. And Also, our living environment are changes very rapidly. The purpose of this study was to analyze the characteristics and trends of future housing reference to ubiquitous housing cases in U.S.A, Japan and Korea. From these cases, reorganized ubiquitous-apartment elements are suitable to our housing environment. To search them, it is investigated to 4 ubiquitous housing examples, such as Aware Home, Toyota's PAPI, samsung raemian's housing gallery and GS E&C's apartment. In this study, we could get types and characteristics and planning elements of ubiquitous housings. The findings showed that many kinds of common network systems were suggested and were acted in limited spaces. In conclusion, it was considered as the one of the most suitable future housing type that had a special feature of the demands of residence and life with free accessibility of information and data. Especially, it is necessary to prepare for coming aging society.

In the ubiquitous computing environment, a ubiquitous vehicle will be a communication node in the vehicular network as well as the means of ground transportation. It will make humans and vehicles seamlessly and remotely connected. Especially, one of the prominent services in the ubiquitous vehicle is the vehicle remote operation. However, mutual-collaboration with the in-vehicle communication network, the vehicle-to-vehicle communication network and the vehicle-to-roadside communication network is required to provide vehicle remote operation services. In this paper, an Internet-based human-vehicle interfaces and a network architecture is presented to provide remote vehicle control and diagnosis services. The performance of the proposed system is evaluated through a design and implementation in terms of the round trip time taken to get a vehicle remote operation service.

Nowadays, ubiquitous computing services begin to be suggested from a few domains such as supply chain, logistics, and location-based services. However, to what extent the services will be successful is hard to be estimated, mainly because a sophisticated service evaluation method focusing on the ubiquitous computing perspective has not been supplied. Hence, this paper alms to build a model to assess the quality of ubiquitous computing service. To do so, an amended model, Ubi-SERVQUAL, is applied to assess the service quality mentioned in ubiquitous computing scenarios. According to the Ubi-SERVQUAL, we found that an actual service with higher quality should consider reliability. responsiveness, assurance and empathy in order to increase customer satisfaction, computer system's intimacy with users and trust.

The spontaneous interoperation is an important characteristic of ubiquitous applications and is closely related with mobility. The mobile components in ubiquitous environments are liable to appear in and disappear from one physical space to another. Because this characteristic certainly influences the structure and behavior of applications, they should adapt themselves to the changed environments by configuring their structure and behaviors. Consequently, developers are faced with the above challenging issue when they design and implement ubiquitous applications. The role concept is an efficient tool to model participant entities, their relationship, and collaboration, so role-based model are appropriate to describe a structure and behavior of software system. But, little attention has been given to reflect characteristics of ubiquitous applications. To tackle the problem, this study considers a ubiquitous application as a software organization which consists of software components and proposes an enhanced role-based application model for supporting spontaneous interoperation.

The concept of ubiquitous is being applied on diverse industry fields as a new growth engine in Korea. With constructing u-City, new services which are called 'ubiquitous services' are developed actively. Even though there are active movement to develop u-service, there is no clear definition of what service can be defined as ubiquitous service. Given that this study proposes a u-service value classification framework focusing on services' characteristics. We conducted experts' group interviews to analyze new operating or developing services whether it can be ubiquitous. Study results show that some services are hard to be defined as u-service, so this study offers possible improvement alternative. The u-service value classification which offers clear definition of u-service can be used for the practitioners offering measurement framework of u-service level.

In this study we designed the killer services for the scene of labor learning in ubiquitous computing. To achieve this study, we have explored the unmet needs of teachers in the scene of labor learning and examined whether the unmet needs could be served by the resources and capabilities of ubiquitous computing. Then, we have crafted a detail killer services that includes value propositions and resource maps by using statistical methodology. Finally, the killer services for the scene of labor learning proposed to serve educational users with the service architecture. The result of this study will be applied to develop new business model in ubiquitous computing as the basic research.

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.

Recently, concerns regarding ubiquitous health have been on the increase according to development of ubiquitous technology and growth of health industry. This study suggested a necessity for market segmentation for the creation of new markets of ubiquitous health business under this background. This paper also analyzed possibile health service industry with characteristics of customers by making an analysis of market segmentation. It was grouped into 4 parts by factor analysis and cluster analysis with raw data collected, the results showed that they would be main potential ubiquitous health service industry. However, some are not significant in statistics, which means that since ubiquitous health industry has not yet been experienced, it probably shows uncertainty about its favour. Finally, the study suggested that a future study should build up more detailed market segmentation data with continuous supplementation.

Especially, system security is very important in the ubiquitous environment. This paper proposes a protecting scheme for security policies in Firewall and intrusion detection system (IDS). The one-way hash function and the symmetric cryptosystem are used to make the protected rules for Firewalls and IDSs. The proposed scheme could be applied in diverse kind of defense systems which use rules.
