This study covers the problem of information overload in workers of different occupations in a home medical care field. This system enables push notification of only highly urgent information by using COI (Conditions of interest) of each worker though specialized information sharing system.

In Japan, the aging of society has become a serious problem that has increased the importance of being able to flexibly share information between medical and nursing care workers. In this study, we examine the real needs of workers in this field and devise and construct a support system that can assist in collecting and acquiring information of int...

In recent years, due to the effects of societal aging, the demand for health-related consultations has been increasing. Recently developments in information technology have made it possible to conduct care consultations by Internet telephony and chat programs. In this study, we propose a remote consultation system that incorporates a collocation di...

Among elderly people who live alone, lack of communication leads to delays in responding to their common medical problems and to the onset or progression of dementia. Here, we propose a communication activation method for elderly people and caregivers. Selection criteria for active communication topics that interest elder people are selected from c...

A life log records man's activity information as digital data. After these life logs are recorded, they are used in order to look back upon an individual's life. There are some problems in the method of life log acquisition. The system needs to install many sensors in a house. In order to install sensors, much initial investment is needed and the u...

The problem of multiple risks is that a countermeasure taken to reduce one risk can increase other risks. To address this problem, a system to support social consensus formation is needed to mitigate the risks. When the number of people necessary for consensus formation is low, such as within an organization, the "Multiple Risk Communicator" (MRC)...

Recently, opportunities that a consumer has to make his/her choices are increasing. And the need of the remote consultation is rising as a means of making better choices efficiently. However, the burden of the expert (consultant) is getting large in the existing remote consultation, because there is a large difference between the number of customer...

In this paper, we propose the supporting method of the risk communications that use the collaborative learning. Using collaborative learning, participant of risk communication can acquire not only knowledge the participant is interested in, but also the intention and knowledge of other party who do not concern the participant’s concern. In the proc...

A paper filtering system that supports the effective collection of related journal papers is becoming important as the technological progress has been rapid. However, previous systems realized insufficient filtering effectiveness, because of lack of available information in abstract part of journal papers that is available to the public. In this pa...

In fields of technological innovation the speed of advance is fast, and while it is difficult for some people to keep up, there are few experts in new technologies. Since consultation is focused on a small number of experts, phenomena such as being unable to obtain sufficient information in a timely manner occur, and are one of the major reasons fo...

The chance to use the Internet as a communications tool has been increasing, and the consultation businesses for customers at remote places are diversifying in their communication media and forms.

There is increasing demand for a filtering system for scientific papers that can be utilized by researchers in business organizations. In conventional paper filtering systems, relevant papers are selected without sufficiently representing the researcher's interest structure, and thus the accuracy of filtering is not satisfactory. The purpose of thi...

According to development of information technology, a variety of social risks have emerged and complex social problems have happened. To cope with this situation, risk communication is useful. In risk communication, negotiation between participants and decision maker is performed and solution for risks is made. Now we have been developing Multiplex...

Risk has increased with the development of an Internet-oriented society, and to what extent that risk can be reduced has become a major issue. Thus, risk communication has become crucial for the formation of a consensus among decision-makers such as citizens. Dealing with risk, however, requires the reduction of risks based on conflicting concepts...
