The objective of the present study is to review of the system, type of care and utility of the Geriatric Health Care Facility(GHCF) in Japan. Geriatric Health Care Facilities in Japan were started with subsidies from the Ministry of Health and Welfare in 1987 to encourage return of the elderly from hospitals to their homes rather than other destinations such as nursing homes or hospitals. Concerning to the type of care, there is the difference between GHCF and other geriatric care facilities(i.e., geriatric hospital and nursing home). GHCF provides both medical and nursing care. The following services are available for the GHCF's user's. As institutional care services, rehabilitation training, ADL exercise, nursing care and management of medicine, are available. For the out-patients, supplying meals, taking a bath, and rehabilitation services, are also available. The medical treatment fee at the facilities is about US $ 1,500 per month. Expenses for meals, daily necessities, shall be borne by the recipient, Those expenses are about US $ 360 per month. In anticipation of the coming of the aging society, the Goverment must be formulated consecutively several vital policies of measures, especially GHCF, for the elderly in the future few years.

Home network is a network composed of devices in home and is being expanded by evolving devices. Also, The number of digital contents in home network has been increasing steadily. But it is difficult to continually protect the rights of digital contents due to lack of interoperability among contents devices. Besides, a license has to be re-issued by DRM sever for contents transfer between devices. Thus, this paper proposes framework which can freely transfer and contents to another device through mutual device authentication and a system that can decrease overload of license management of the DRM sever and that enable device outside home network to use contents through user authentication.

As the internet is widely distributed. the intelligent search agent is commonly used to meet the needs of user. But these Intelligent multi-agents are so independent each other that they can not give reliability of information and also have difficulty in coping with the dynamic distributed environments due to the short of cooperation abilities among multiagent. To resolve these problems. this paper proposes the mechanism for efficient cooperation and information processing by creating agency within broker agent and clustering multi agent's agency using neural network. For reliability of information. we also propose the multiagent management mechanism that can improve the information update problems which are in existing search systems and evaluate the performance of this research through simulation.

Due to the rapid popularization of mobile multimedia devices and the Internet as well as the realization of high-speed data transmission and large-volume data recording media, high quality content distribution and ubiquitous information services are making progress and a new type of information distribution and network sharing service has gradually emerged into the market. It is capable of utilizing terabyte sized home servers also in private homes. Under these circumstances, in distribution of content over shared networks, it is crucial to establish DRM (Digital Rights Management) technologies to protect the content from illegal copying and usage. A truly successful DRM system must be built on open worldwide specifications and provide maximum interoperability and user acceptance. An open interoperability of DRM is able to construct highly expandable PKI based DRM, targeting usage between systems, considering the expansion of recent content distribution services and clients This document gives protocol specifications for the exchange of rights information between the DRM module, description of specifications for rights information and encrypted content formats.

The purpose of this study was to examine the dissatisfaction level of consumers buying foreign goods through Internet shopping malls and their complaint behavior. As there is growing demand for foreign brands along with a rapid increase in the Internet user population, a lot of ongoing studies have focused on Internet-based transaction. The dissatisfaction level of selected consumers was checked in terms of system, price, quality, information/hype, shipping and refund/exchange, and it's found that complaint behavior linked to refund/exchange was most prevalent. The most dominant way for them to respond to such situations was talking friends, relatives or neighbors about that. And they had an intention to buy foreign goods through Internet shopping malls again to greater or lesser extents, though they were unsatisfied. It indicates that the consumers didn't have a wide option in the consumer market.

QR/NFC tags have been utilized in various fields like exhibition, museum, and so on, but they have a drawback that they are read-only fundamentally. We devise a novel device called a smart memory tag (below mem-tag) which is supplemented with the write function through combining a flash memory into a NFC tag. A mem-tag is composed of an NFC tag, an MCU, a flash memory, a bluetooth module, and a battery, and is inter-operating with smartphones via bluetooth communication. It can be used in a bulletin board to support writing replies and in a check-in service to verify the presence of the site. What matters is that users' inter-operations are borne to be asynchronous, which leads to the energy consumption to wait for users' actions. Sleep mechanisms and asynchronous MAC protocols used in ubiquotous sensor networks cannot avoid the consumption of battery. In this paper, we propose a touch and play scheme for minimizing the consumption of battery that the MCU wakes up and PLAY when a user TOUCH the mem-tag. We implemented the system to show that our scheme lets the mem-tag work 50 times longer than the sleep and wake-up scheme.

Multidisciplinary Design Optimization (MDO) is an optimization technique considering simultaneously multiple disciplines such as dynamics, mechanics, structural analysis, thermal and fluid analysis and electromagnetic analysis. A software system enabling multidisciplinary design optimization is called MDO framework. An MDO framework provides an integrated and automated design environment that increases product quality and reliability, and decreases design cycle time and cost. The MDO framework also works as a common collaborative workspace for design experts on multiple disciplines. In this paper, we present the architecture for an MDO framework along with the requirement analysis for the framework. The requirement analysis has been performed through interviews of design experts in industry and thus we claim that it reflects the real needs in industry. The requirements include integrated design environment, friendly user interface, highly extensible open architecture, distributed design environment, application program interface, and efficient data management to handle massive design data. The resultant MDO framework is datasever-oriented and designed around a centralized data server for extensible and effective data exchange in a distributed design environment among multiple design tools and software.
