R&D Exhibit at the NTT Group Communication EXPO

　For three days from December 20 to 22 2005, the NTT Group held the NTT Group

Communication EXPO at the Tokyo International Forum to commemorate 20 years since

the privatization of NTT.

　This event included a keynote speech from our President Norio Wada, seminars, and

various exhibitions on the theme of NTT’s preparations for a ubiquitous broadband society.

　In the exhibitions, we introduced NTT’s historical role in the development of communication

and recent developments in communications. These were presented three zones: “The

History of Communication”, “Future Square”, and “Technology Lab”. This event helped to

present our image of the future of communications to about 10,000 visitors over three days.

　Our recent R&D achievements were presented and introduced centered around two

zones: “Future Square” and “Technology Lab”. In the “Future Square”, exhibitions were

presented based on the four keywords feel, learn, live and meet, where visitors were able to

experience first-hand the lifestyle that will be offered by telecommunications in the near

future. The exhibitions in the “Technology Lab” related to five themes: natural communication,

net life technology, net security, key technologies for high speed and high capacity, and

ecology & science. In this way, we introduced visitors to our technological connections and

advanced technical abilities, including the diversity of NTT’s research and development

work.

　At the EXPO, visitors were able to experience the wide variety of achievements that NTT

is continuing to make in research and development towards the realization of a ubiquitous

broadband society. They showed a great deal of interest in the future trends of this field,

and were able to take part in meaningful discussions.“Technology Lab” exhibition

NTT Communication Science Laboratories Open House 2005

　NTT Communication Science Laboratories Open House 2005 was held on June 2 and 3, 2005 at the NTT Keihanna Building to present research results to the general

public. Based on the theme of “Creating Intelligence to Fill Communication Space”, Open House 2005 featured a series of lectures and exhibits on current research

divided into the five categories of search intelligence, communication intelligence, perception intelligence, logical intelligence, and interwoven intelligence of the future.

　Five lectures were given in each of the above five categories. The first, titled “Storytellers from the Future”, was presented by Shigeru Katagiri, then the director of NTT

Communication Science Laboratories. A total of 36 research exhibits were prepared with eight or nine exhibits allocated to four of the above categories. Only two exhibits

were presented for the research category of “interwoven

intelligence of the future”, but these encompassed many of

the other exhibits under the theme of “The Future

Envisioned by Communication Science”. Open House

2005 opened its doors to a total of 1,017 visitors giving

them a first-hand introduction to research at NTT

Communication Science Laboratories. This event also

enabled NTT researchers to interact with customers and

receive many valuable comments and suggestions.

Members of the press were also in attendance and Open

House 2005 received news coverage in various media. Research exhibit sceneLecture by director Shigeru Katagiri

Universal IT Design Symposium in Fukuoka

　The “Universal IT Design Symposium in Fukuoka” was held on January 30, 2006 at NTT Yumetenjin Hall in Fukuoka, Kyushu, Japan sponsored by NTT

Cyber Solutions Laboratories, cosponsored by Kyushu University and NTT West Fukuoka Office, and supported by the Kyushu-Yamaguchi Economic

Federation. This symposium was planned and carried out to “publicize NTT’s interest in universal design and to present NTT’s stance on universal design

in cooperation with the entire NTT Group”.

　The symposium included various lectures from universal design

concepts to specific examples and welcomed Chika Sekine from UDIT,

Inc., Yoshitsugu Morita from Kyushu University, and Seiji Shimada from

Kumamoto prefecture as lecturers. It also featured a presentation from

NTT on the trials it has been holding on “Weldery Communication

System”, monitoring services for the elderly and a demonstration of

these services. These and other research results from NTT Laboratories

attracted much interest among the 202 symposium participants. Panel

discussions were also held and lively discussions took place.

Participants asked many questions on IT technology and universal

design resulting in a meaningful symposium for all concerned.Hall entranceLecture scene

Core Technology Symposium

　At NTT Cyber Communications Laboratory Group, we have planned and held a core technology

symposium every year since 2004 in order to reinvigorate our research activities and enhance our

presence with regard to our five R&D themes (core competences) of (i) visual media, (ii) speech, acoustics

and natural language, (iii) human interfaces, (iv) human appliances, and (v) media-based computing.

　In 2005, the NTT Cyber Communications Laboratory Group and NTT Cyber Solutions Laboratories

organized the third core technology symposium which was held at the Kokuyo Hall in Shinagawa on

December 1.

　At this symposium, presentations and panel discussions were held on the theme of “Portal Technology

Symposium — Targeting the net community of the near future”. The symposium proved to be a success,

with about 200 people taking part. The participants were introduced to the current state of society

concerning media computing, and to the achievements of research at NTT Cyber Solutions Laboratories. Panel discussion at the symposium


Activities in Open Source Software Communities — Linux and PostgreSQL —

Communication Support System for Elderly Care and a Social Experiment at Kijocho, Miyazaki

　In Japan, the aging society continues to grow with one in four people expected to be senior citizens by 2015. To help the elderly lead healthy lives with a feeling of

well-being in this society, NTT Laboratories have developed the “Welderly Communication System” to provide monitoring and communication functions in a bidirectional

manner (between elderly persons and their families or local care volunteers, public welfare officers, etc.). A particular feature of this system is the use of infrared

sensors to detect the state (presence) of both parties at all times and the presentation of that state on respective terminals. When one party wishes to communicate with

another party, the former can do so by either audio/visual calling or text messaging according to the state of the latter using simple operations provided by the system.

　This system has been used in trials since March 2005 in Kijocho, Miyazaki prefecture, a local area that, though thinly populated, has been provided with a fiber to the

home (FTTH) infrastructure. In these trials, elderly users have said that the system helps make their everyday life more enjoyable, while volunteers and public welfare

officers have said that it enables them to provide the elderly with an even higher level of care. Our objective for the future is to commercialize this system by lowering the

cost of the communication terminals.

NTT’s contribution to the PostgreSQL community

Example of a bulletin on NILFS in the Linux community

　We have played an active role in the activities of OSS*1 communities, mainly with regard to the Linux

operating system and the PostgreSQL database management system.

　For Linux, we have made proposals to the Linux developer community regarding patches to improve the

file system reliability. Seven of these patches have been incorporated into the official Linux kernel. We

also released NILFS*2, a log-structured file system which increases the availability of data, as open source

software. This has been highly evaluated as a major contribution from Japan to the development of Linux,

and further developments are eagerly anticipated. We expect these activities will draw attention to the

reliability of Linux, and encourage users to apply Linux to large-scale reliable systems.

　With regard to PostgreSQL, we have contributed to the developer community by proposing 15 patches

including performance tweaks and bug fixes, five of which have

been incorporated into the current release, PostgreSQL 8.1.

These patches effectively increase the database throughput

by about 70%. We have also made efforts at the Japan

PostgreSQL Users Group to enhance NTT’s presence and

expand the PostgreSQL community through activities such as

technical presentations (4), contributing articles to the group

newsletter (2), and building ties with the Database Society of

Japan.
