Content services for silver users on the ubiquitous technologies are getting attention as a new business model, monitoring users in real-time on the real-world and/or cyber-world. A lot of business and service model have been developed to apply silver or elder user. This study explained a state-of-the-art silver IT service to innovative services for users, ranging from home and finance to support for healthcare and living. Due to the variation of subtle terminologies, this study was conducted to restructure an adaptive terminology including some definitions. Current silver IT service model has been evaluated from the technical, functional, and business analyst, and its suitability has also been expressed in a proposed model and service. The purpose of this study was to propose a systematic approach of new IT service business model for silver users. A proposed model was described to explain the feasibility of the silver IT industry.

In general, there are 3 subjects of discussion in education field; namely past, present and future. Related with those facts, there is several information or knowledge that relatively hard to be presented in the real world. In this matter, digital content shows its contribution especially in the education field. Digital content can virtually represent the information or knowledge that seems to be difficult to be visualized in the real world before. In this project, researcher develops a mobile device's application that consist the skeleton's 3D virtual content. This application is expected to solve the above explained problem that usually appears during learning human skeleton in senior high-school's biology class. Besides, the application of digital content will make the learning process become easier because the student will have a visual learning tool. Last, the mobile device that is used in this prototype has offer an important beneficial namely mobility beneficial, so that the user can access the content anytime and anywhere.

FIAS(Flood Inundation Analysis System) using Arc/Info is developed and applied to the Namhan River basin. The DWOPER model is revised and expanded to handle simultaneous multiple overtopping and/or breaking, and to estimate the inundated depth and extents. The model is applied to an actual levee overtopping case, which occurred on August 23∼27, 1995 in the Namhan River. Stage hydrographs inside and outside of the levee are compared, then inundated discharges from overbank spilling are computed. The Graphic User interface is developed with AML. Two- and three-dimensional inundation map by Arc/Info are presented. The computed inundation extends agree with observations in terms of inundated depth and flooded area. The FIAS is useful for the analysis of flood hazards and preparation of inundation map for river basins.

The study is based on the technology-organization-environment (TOE) model which, attempted to determine the factors that are going to influence ICT adoption. The proposed research model evaluates the interplay among technological context (IT infrastructure, system security, and user capacity), organizational context (top management commitment, and innovations strategies), environmental context (quick response to the external agencies, interactive network infrastructure, and competitive pressure) and ICT adoption (productivity growth, organizational change, and competitiveness). Data were collected from 243 senior executives of full member firms of the Bangladesh Garments and Manufacturers Association (BGMEA) of examining the relationships among the constructs in the proposed framework utilizing structural equation modeling (SEM). The analysis of TOE factors revealed that environmental, organizational, and technological factors have a significant impact on the successful implementation of ICT tools. The study also discusses implications for management practitioners.

Purposes: This study was to validate the Robotic Smart Work System that can provides better working conditions and high productivity in unstructured environments like bio-industry, based on a tele-operation system for fruit harvesting with low cost 3-D positioning system on the laboratory level. Methods: For the Robotic Smart Work System for fruit harvesting and cultivation management in agriculture, a vision based tele-operating system and 3-D position information are key elements. This study proposed Robotic Smart Farming, an agricultural version of Robotic Smart Work System, and validated a 3-D position information system with a low cost omni camera and a laser marker system in the lab environment in order to get a vision based tele-operating system and 3-D position information. Results: The tasks like harvesting of the fixed target and cultivation management were accomplished even if there was a short time delay (30 ms ~ 100 ms). Although automatic conveyor works requiring accurate timing and positioning yield high productivity, the tele-operation with user's intuition will be more efficient in unstructured environments which require target selection and judgment. Conclusions: This system increased work efficiency and stability by considering ancillary intelligence as well as user's experience and knowhow. In addition, senior and female workers will operate the system easily because it can reduce labor and minimized user fatigue.

This research surveyed college students in Korea on their satisfaction for e-book services provided by university libraries. Their usage behavior was investigated, and the satisfaction rate for e-book usage and its service quality were analyzed to comprehend the status of e-book usage. The analysis showed that overall satisfaction for e-book service of university libraries was 2.93 on average. Moreover, the more frequently a student used the service, the more satisfied the student was; junior/senior-level and graduate school student groups showed higher satisfaction for e-book service than freshman and sophomore students. The most influential factor for satisfaction based on the e-book service quality was the content of the service, followed by the library support service system. Based on the findings, reinforcement of library public relations and user education, and the maintenance of the variety and up-to-date status of the contents were proposed to stimulate future university library e-book services.

While one person household and nuclear family have been increasing, supermarkets began to launch home meal replacement(HMR) promotion. Each brand competes over various types of HMR such as box lunch. In particular, the sales of HMR have been increasing due to one-person households. Experts predicted HMR market will be increased in the future as well. This study presents design evaluation with regards to HMR package design for elders. The methods of this study are: First, research literature review on senior society and analyse the design for both domestic and foreign HMR products. Second, survey on product design for evaluation was conducted. Third, user's evaluation survey was conducted on elders. As a result, containers mostly came in cup or box shaped package designs. The package provided both still and illustration image of food. The HMR design for elders are recommended as follows: first, HMR should be service designed for users. Second, the design should be for elders as well. Third, the design should be empathetic and abundant. For user-interface, the packaging material shall not be slippery and the shape of grip should be considered thoroughly for the elder's design.

In the distributed-computing environment, applications or users have to share resources and communicate with each other in order to perform their jobs more efficiently. In this case, it is important to keep resources and information integrity from the unexpected use by the unauthorized user. Therefore, there is a steady increase in need for a reasonable way to authentication and access control of distributed-shared resources. In RBAC, there are role hierarchies in which a higher case role can perform permissions of a lower case role. No vise versa. Actually, however, it is necessary for a lower case role to perform a higher case role's permission, which is not allowed to a lower case role basically. In this paper, we will propose a permission delegation method, which is a permission delegation server, and a permission delegation protocols with the secret key system. As the result of a permission delegation, junior roles can perform senior role's permissions or senior role itself on the exceptional condition in a dedicated interval.
