Preface

1. Preface
The Research Institute of Electrical Communication (RIEC) has continued to excel as the only
research institute affiliated with a national university that addresses information technology since its
establishment in 1935. In 1994, our research institute became one of the National Centers for
Cooperative research, addressing “theory and applications of intelligent information science andcommunication technology”. In the last several decades Information science and communication
technology have rapidly developed and brought about great social changes including globalization ofcommunication and physical distribution.
To meet the needs and demands of a new age, in 2004 we reorganized our institute into four researchdivisions, two research facilities and one research center. Research center for 21st century information
science and technology has established to realize the rapid commercialization of technologies
developed at the institute within a 5years horizon. Two research facilities with 8 research groups
working on next generation technology have been established with a 10 years horizon. The Laboratory
Nanoelectronics and Spintronics, one of the facilities, is carrying out fundamental research into
high-speed semiconductor devices and advanced nano/spin electronics. The Laboratory for Brainware
Systems is working towards a new computing system, in which human-being functions areincorporated into information communication technology. The Four Research Divisions are working on
basic research for information communication with a 20 years horizon. The Information Devices
Division carries out research into materials and devices for communication technology, whilst theBroadband Engineering Division focuses on the development of new technologies for the transmission
and storage of vast quantities of information. The human Information Systems Division researches
into intelligent information processing and the Systems and Software Division is developing advanced
system software for the next generation information society.
Nowadays there are a lot of discussions on restructuring the research and education systems inJapan. Even the national universities including affiliated institutes are not exceptions, then thoseshould be discussed based on the academic freedom and the university autonomy, which are thewellsprings of creative power and innovation resulted in. RIEC has significantly contributed to theinformation and communication technologies as an innovation center since its establishment, in which
it frequently took several decades to realize the commercialization of the innovative ideas/technologies
developed at the institute. We intend to continue to work hard to ensure the progress of theinformation and communication technologies. In addition to research activities, we have a mission to
train researchers and engineers to internationally high standard through close co-operation with thefive departments in the fields of electrical communications at Tohoku University’s School ofEngineering and the Graduate School of Information Sciences.
We have published an annual report every year since 1994 summarized our own activities, anddistribute it researchers working in the field of information sciences and technology. It is also utilized
as self-checking and self-evaluation materials. Please let me hear your frank criticism.

Nation-wide Cooperative research projects

4. Nation-wide Cooperative Research Projects
The Institute has a long history of fundamental contributions in many fields of engineering andscience that include the fields of semiconductor materials and devices, magnetic recording, opticalcommunication, electromagnetic technology, applications of ultrasonics, acoustic communication,
non-linear physics and engineering, and computer software. On the basis of this rich historicalbackground the Institute was designated as National Center for Cooperative Research in 1994.
Accompanying Tohoku University’s transformation to “a national university juridical entity” in
April,2004, this institution plays a leading role on the world stage, as its researchers, both domestic
and foreign, continue the task of “investigating the theory and application of universal science andtechnology to realize communication, to the enrichment of humanity.”

In such background, the Institute organizes Nation-wide Cooperative Research Projects bycoordinating its activities with research workers. The main themes for Cooperative Research are
selected annually by the Committee for Cooperative Research. Then invitations for project
proposals and participation are extended to university faculties and government laboratories aswell as industrial research groups. Each project approved by the Faculty Council of the Institute iscarried out by a team of researchers that include members of the Institute as well as outside
participants.
The advisory Council which includes members from other institutions has an advisory function to
the Director in defining the general direction of the research at the Institute and its Nation-wide
Cooperative Research Projects.
The Project Judging Committee that includes members from the outside of Tohoku University
has a judging function for project proposals. The purpose of the Project Steering Committee is theproper operation of approved projects.

Periodicals published by the institute

8. Periodicals Published by the Institute

The Institute publishes the following two periodicals to inform readers on recent research results of
the Institute.

1. The Record of Electrical and Communication Engineering Conversazione Tohoku University

This journal aims at providing an opportunity to publish research results of the Institute as well as
the result of the Departments of Electrical Engineering, Communication Engineering, Electronics
Engineering, and Information Engineering of the Faculty of Engineering. Since the journal also aims
at publishing general research activities of the Institute and of the Departments such as records of the
final lectures of retiring professors, records of the Institute Symposium, and reviews.

The name of the Journal ‘Conversazione’ is attributable to the ‘Tuesday Conversazione’ at the
Department of Electrical Engineering, which had been held once a week on Tuesday since around 1920.
Minutes of the meetings had been distributed to researchers outside of the University via various
routes and therefore some of them had been referred to as 'Records of Tuesday Electrical Engineering
Conversazione Tohoku University' with the result that they came to be treated as official publications.

Though the meeting was once interrupted by World War Two, it was restarted in 1947. In 1952, thepublication of the records was succeeded by the Institute and the records have been published asperiodicals, two times a year recently, since No. 1 Vol. 21 was published in July, 1952.

2. The Annual Report of Research Activity at the Research Institute of Electrical Communication,
Tohoku University

Published annually since 1995. This report details the activities of each research division andresearch facility. Also included are reports on nation-wide co-operative research projects, international
symposium and seminars organized by members of RIEC, and the reports and evaluation on the RIEC
advisory board members.

English edition(digest version of Japanese edition) has been publishedsince 2007.

Afterword

10．Afterword
Recently, two disasters stroke Asian area successively. One was that Myanmar suffered greatdamage from the cyclone, and the other was the great earthquake attacked Sichuan Province in
China. In the two disasters, there left unbelievable number of victims. In the case of cyclone, it is
supposed that indiscreet usage of energy and industrial products causes the greenhouse effect andclimate changes, which might brew stronger cyclones. In the latter case, houses and buildings
without adequate measures for quake might cause heavy casualties. Even the modern science andtechnology could not keep from occurring disasters, but could reduce the damage from them. To ourregret, the modern science and technology is not always properly used to minimize the damage fromthe disasters. On this opportunity, we need to reconsider how the modern science and technology
should be used.
With regard to information science and communication technology, similar situation has developed.
They brought the globalization of communication, resulted in changing the human behavior and thesocial structure. They are surely convenient, while produce digital divide, autistic persons and new
kinds of offence. It is a universal that the natural sciences and technology are neutral against rightand wrong, so the human beings are responsible for the usage of them. If the natural sciences andtechnology give negative effects, we need to change the way of usage or to overcome the problems by
developing the technologies. The science and technology should be progressed to properly support
the human life.
We have philosophically redefined in 2001 what RIEC should be. “It is possible for human society
to sustainably develop, only when a barrier-free communication is guaranteed. Devoting ourselvesto the research of information science and communication technology, we will contribute to theprosperity and development of our own country, and extensively to the progress of the culture andwelfare of mankind.” All the staff in our institute will assume the responsibility to information andcommunication systems in Japan, and each research activity should be approved by the Japanesenation. Academic freedom how to approach the problems is a right of all researchers, but each isaccountable for his/her own study. For doing our duty, we need to show what we are doing and what
the future of the information science and communication technology will be. This annual reportpresents our daily research activities, so I greatly appreciate your frank and critical comments on
our activities.
