Current difficulty to formulate complex systems may be resolved by introducing scale constraints thanks to the development of advanced information technology. This paper concerns the identification of the first principle equation that governs complex system beviour by applying machine learning and trial study of the relationship between the public affinity and earthquake risk. The basic research of the discovery of the first principle equation has been made in the area of artificial intelligence, a kind of engineering. This outcome was extended to socio-psychology. Thus the framework is considered to be a symbiosis of natural and cultural sciences.

We have conducted a survey of documents, magazines and other literature as to the historical origin, development of the use and the current common concepts of the terms “symbiosis” and “symbiosis society” now being used in various forms. We have eventually found out that the common concept of many people is that the term, “symbiosis society”, is a society aimed at the establishment of a new combined society under the approval of the “co-existence” of various alien concepts.

It is commonly said that both the renewable new energy and nuclear energy are effective for preventing global warming, but the both have their own problems on real introduction. In this paper, we will first point out that the symbiosis with society is the important aspect for the enterprise activity, then the problems of the new energy and nuclear energy will be made clear by social investigation, and propose the new concepts of enterprise models to solve the raised issues for those energy sectors.

To improve the usability of plant operation systems without decreasing plant safety and reliability, we need an advanced human-machine system that is easy to use and highly tolerant of human errors. Our goal is to upgrade basic functions of human-machine systems in the plant-operation through the use of advanced human interface techniques. This paper describes an outline of that project.

The handicap about a protecting people with intellectual disabilities’ communication in a community poses an important problem. Activity of NPO enjoy-communications is reported as this handicap measure by the Internet use. NPO enjoy-communications is carrying out the personal computer school for a protecting people with intellectual disabilities. While letting a school pass and having the new communication method acquired, it aims at having a protecting people with intellectual disabilities enjoy communication with various volunteer staff in the environment different from usually. Moreover, the effect of a spread of the recognition in a community has been acquired by looking for a volunteer from a community. Corresponding to a protecting people with intellectual disabilities’ needs, NPO enjoy-communications has also tried the improvement of activity from now on so that the recognition in a community may be extended further. Thus, although the measure is taken, finally it is necessary to aim at normalization by the community formation including the protecting people with intellectual disabilities using the Internet as one measure turned to symbiosis of a community with the protecting people with intellectual disabilities.

We investigated various problems involved when it takes long for physically-challenged people to get to some place and collected much information helpful in the realization of a successive barrier-free system. As a result various problems has come to light. People with defective eyesight point out the lack of fences to prevent them from falling a platform. People with defective hearing point out the lack of signs appealing visually to them in special expresses. People with their defective upper limbs and people with their defective internal organs point out the presence of a lot of stairs between a wicket and a platform in a railway station. People with their defective legs and people with their defective trunk point out the presence of much space between a car and a platform in a railway station. And intellectually-challenged people point out the lack of information about trains at a wicket.

This research is about a human-computer interface equipment such as a wrist watch and bracelet type without a keyboard. This interface can be used in all the scenes everyday life and also non-everyday life such as walking and having meals.

Information education which is becoming compulsory at school in Japan does not teach human interface very much yet. Human interface, on the other hand, is currently attracting attention and plays a significant role in making the society accessible to everyone. For example, information technology with an accessible interface is used for supporting the independent lives of many people with disabilities and elderly people. Hence learning human interface can become an important part in today’s information education, as well as learning information processing and the operation of hardware and software. In this study, university students and junior high school students have group activities with kindergarten pupils where they create multimedia software together. In this cooperative work among people from different age groups, it is hoped that they understand the difference of each other and the students find the need to design the software enjoyable and accessible to the kindergarten pupils, which might develop their creativity toward information technology useful for everyone.

Towards harmony between human and society for the sustainable development of humanity, we had constructed a web site for “Sym-bio Society Formation” as a forum of knowledge sharing and mutual communication. Additionally, towards providing friendly place for dialogue between multigenerational people about various social issues, we have considered a web site using network communication. The character agent was introduced to navigate into a community and to provoke participants’ message. We have conducted the experiment to research the evaluation and effectiveness of the web site with respect to evocation of messages, usefulness of navigation, and so on. In consequense, we have found that the usefulness of the navigator would have relation with the familiarity to the networked community.
