  • In ubiquitous computing environments, users want to receive the robot services regardless of various physical status or devices such as time, place, various sensors, and high-performance servers. Thus, the ubiquitous service robots have to provide users with automated services according to situational information that they properly recognize. Beyond these problems, robot software has to establish a foundation to support the functions with the network infrastructure that are not able to be solved by a single independent resource. On the basis of a robot middleware that is capable of minimizing dependencies among hierarchy structures, the robot software also has to provide execution environment to control the flow of robot application services. In this paper, we propose a layered architecture to provide users with automated services through ubiquitous robots. The proposed architecture is based on CAWL (Context-Aware Workflow Language) and RSEL (Robot Services Execution Language). CAWL easily represents the flow of robot services from user application service levels, and RSEL is able to support the composition and reusability of robot services through abstraction of robot device services. In our experiments, we applied the proposed architecture to an example of "booth guide robot service".

  • The purpose of this study is to suggest institutional reformation of public office facilities by analysis the status of services on welfare for the aged and disabled. For this study, we have researched and analyzed on two different aspects. The aspects are space composition of public office facilities, welfare systems and service support within region. And we can get the following important points as conclusion; (1) We need to consider on not only access for public office facilities site but also the connection on business such as block plan on zone and connection between quarters. Architectural plan has to be considered. (2) Most of the public office facilities use human service resources as a supporting system for shortage of convenient facilities. Variety of welfare services are required. (3) We need to secure various programs and space for local peculiarities and social demand.

  • As web services have become an important architecture solution, web service composition applications are developed actively. A mobile application supporting multiple services requires a complex user interface so that the interface needs to consist of more than one view and to provide a way to navigate between views. In this paper, we presented a formal way to analyze a set of views for a given service specification, and a relation model between views and methods. We then provided an algorithm to generate codes for service method calls and navigation between views. Therefore, with an optional user configuration input, we could automatically generated XForms codes from the web service specifications. Finally, we developed a proof of concept implementation of XForms browser to show that the generated codes works well as an interface for web service compositions.

  • Influences of different seeding dates on growth, seed yield, fatty acid composition and oil content were investigated in flax plants for two years. The results indicated that plant height in early seeding date was higher than that of delayed seeding dates during first season. Furthermore, seeding date also significantly affected the ripened seed rate and the rate increased with the delay in seeding date in first season. Seed yield in the first crop season was significantly higher than the second crop season. Palmitic acid showed variation in different seeding dates. Contrarily, stearic acid was stable and did not changed by different seeding dates. Linolenic acid was found in highest amount in all seeding dates consecutively in two cropping years. Highest oil content was recovered from the seeds of flax sown at 29 Apr. and May 9 in first and second cropping year respectively.

  • Nowadays, the web service was based on composing the e-business and distributed computing environment. But existing workflow management systems have many problems with the interoperability between companies because they are made before most web services. For these problems, the workflow based composition language such as the Business Process Execute Language for Web Services (BPEL4WS or BPEL) appeared in expressing the web service composition. In this paper, we present an event based rule management system architecture that executes automatically the BPEL using the Event-Condition-Action (ECA) rules. The event based rule management system consists of the event manager, rule manager, and Jess. The Jess is the part of executing and deciding the condition.

  • The aim of this field experiment was to investigate the possible effects of mepiquat chloride (TE) and trinexapac-ethyl (MC) on oil composition, seed yield and endogenous gibberellins content of flax cultivar. Foliar application of plant growth retardants mepiquat chloride (0.897, 1.794 and 2.691 kg a.i. $ha^{-1}$) and trinexapac-ethyl (0.756, 1.512 and 2.668 kg a.i. $ha^{-1}$) had significantly increased seeds ripening rate and seed yield. In contrast, plant height was decreased by foliar application of MC and TE. The application of MC significantly increased seed oil yield (730 kg $ha^{-1}$ by 27.0%) compared to the control. Seed and oil yield, and unsaturated fatty acids (oleic acid, linoleic acid and linolenic acid) were increased by foliar application of MC.

  • User Experience (UX) and Experience Innovation have been emphasized in the process of New Product Development (NPD). However, previous works which were conducted within the theme of UX mostly focused on the fragmentary aspects of user's experience in a specific usage-context only. For this reason, it is always hard to deal with questions on how to define the abstract concept of UX and how to apply this important keyword in actually NPD process both for satisfying potential users and for setting a market strategy. To address this issue, we focused on the fact that UX has an aspect of composition like pattern and structure. It means that we can understand the context of UX with clarifying characteristics of relations between user and experiential objects. Also, we referred to two sub-concepts of Complexity, Density and Centrality, as representative characteristics of relations in usage-context. Based on this theoretical background, we attempted to find UX design principles and concepts for NPD from the actual example cases of products and services in the real market. From these whole study process, we expect that our findings could have implications for academic and practical areas within the theme of Human-Centered Innovation.
