Overview
In today's society, in which technological innovation and market changes are accelerating, NTT EAST is committed to solving problems of local communities while valuing the ties that it has cultivated with those communities over the more than 100 years in the telephone business. We interviewed Hiroshi Tanabe, senior executive vice president of NTT EAST, about his thought on the use of technology to solve social problems and why he has been focusing on helping front-line employees shine.
Front-line Researchers
- Masaaki Nagata, Senior Distinguished Researcher, NTT Communication Science Laboratories
Overview
Research on machine translation using neural networks has made rapid progress, and the accuracy of machine translation has improved considerably. Although websites and smartphone apps providing machine translation have become more popular, issues with accuracy remain. To address such issues, researchers are studying more advanced translation technology that reflects context, situation, and culture. We interviewed Masaaki Nagata, senior distinguished researcher at NTT Communication Science Laboratories, who is researching context- and situation-based neural machine translation, about the progress of his research and what it means to be a researcher.

 Research and Development on Technologies for Transforming the Global Environment from a Space Perspective
Abstract
NTT Space Environment and Energy Laboratories was established in July 2020 to develop innovative technologies for regenerating the global environment and achieving a sustainable and inclusive society. We are the first NTT laboratories with "space" in our name, but our purpose is not to conduct research on space itself. Rather, we study the Earth from the perspective of the space environment, including the Sun, and take on challenging studies with the aim of transforming the future of the global environment from dynamic viewpoints.

Abstract
This article outlines next-generation energy technologies to enable the use of overwhelmingly clean and inexhaustible energy sources, which are expected to be put to practical use, and carbon dioxide (CO2)-conversion technologies to effectively fix CO2 and reduce the total CO2 emissions of business activities to zero or less.
- Energy-distribution Platform Technologies toward Zero Environmental Impact
Abstract
The use of renewable energy has been increasing, but further adoption will require effective distribution of energy and energy resilience. The Energy Network Technology Group of NTT Space Environment and Energy Laboratories is researching and developing virtual energy demand/supply control technology to enable full use of renewable energy and next-generation energy-supply technology based on direct current microgrids to provide a stable supply of power to regional areas even if the supply of commercial power is interrupted. This article introduces these technologies.

Abstract
We introduce ESG (environmental, social, and governance) Management Science and Technology for achieving a sustainable and inclusive society with respect to recent climate changes and problems related to human rights. We also analyze the relationship between the global environment and socioeconomic systems to predict the future and identify long-term corporate risks as well as opportunities for corporations to generate new revenue and enhance their corporate value.
- Proactive Environment Adaptation Technology for Living Safely and Securely
Abstract
Changes in the Earth's environment are expected to have a significant impact on our social life. In this article, environmental adaptation technologies (technology to develop a platform for collecting and analyzing all types of information on the Earth, meteorological forecasting/control technology, lightning control technology, and electromagnetic barrier technology) for predicting various effects of changes in the Earth's environment, responding to such effects proactively, and achieving a resilient society by enabling humans to adapt to such changes are introduced.

- Physical-condition Management Technology for Creating More Comfortable Work Sites
Abstract
Physical-condition management is becoming more important to improve the safety of work sites, such as preventing heat stroke caused by intense heat. We at NTT Device Innovation Center have developed a physical-condition management technology for creating more comfortable work sites by using the wearable-device sensors and data-analysis technology we have developed thus far, and the knowledge of thermal and exercise physiology in collaboration with specialists. This article introduces the problems with physical-condition management, how our technology can solve these problems, and the results from verifying our technology at an actual work site.
- Non-invasive Biological-information Sensing Using Photoacoustic Measurement Technology
Abstract
Biological-information sensing technology for simplifying the measurement of blood components without drawing blood has been attracting attention. NTT has been researching and developing biological-information sensing using photoacoustic measurement technology that combines the ability of light to selectively measure specific biological components and the ability of sound (ultrasound) to propagate through the human body. In this article, we introduce non-invasive biological-information sensing technology using photoacoustic measurement technology with the aim of collecting various types of information from within the body.
- Derusting Technology Using High-power Laser Device
Abstract
Rust removal in narrow spaces that are inaccessible to human hands or electric tools is a challenge in derusting operations essential in prolonging the life of steel towers and other communication infrastructure facilities supporting communication services. We are developing technologies for efficient derusting using high-power laser devices developed by NTT. In this article, we introduce a compact and lightweight derusting technology incorporating a high-power laser device called a diffractive optical element.
- Technology for Predicting Hydrogen Embrittlement in Reinforcing Bars of Concrete Poles
Abstract
A concrete pole, which is an important part of the communication infrastructure supporting communication services, requires significant maintenance costs to ensure its safety. If hydrogen embrittlement, a phenomenon by which reinforcing bars in concrete poles deteriorate, could be accurately predicted, it would be possible to maintain and manage concrete poles more safely and economically. A technology for predicting hydrogen embrittlement in reinforcing bars inside concrete poles that involves using an accelerated-hydrogen-embrittlement test and statistical data analysis is introduced.

- Neutron-energy-dependent Semiconductor Soft Errors Successfully Measured for the First Time
Abstract
Problems caused by neutron-induced soft errors in electrical devices are becoming increasingly common in various applications. The neutron-energy-dependent soft-error rate is indispensable for evaluating the frequency of such errors in different neutron environments. We observed the energy-dependent neutron-induced soft-error rates continuously over the energy range of 1¡Ý800 MeV at the Los Alamos Neutron Science Center, USA. This measurement was made possible with a method we developed that uses extremely fast circuits built into field-programmable gate arrays coupled with a neutron time-of-flight technique.
Global Standardization Activities
- Recent Standardization Activities of Optical Connectors in IEC
Abstract
Optical communication networks and datacenters worldwide use a huge number of optical connectors made in many countries. Optical connectors are products that require precise components because a dimensional error of only 1 ¦Ìm can affect the optical signal quality. To ensure the compatibility of connectors, it is essential to internationally standardize the component shapes, connector performance, and the measurement methods for testing them. This article introduces the standardization activities and recent trends in optical connectors.
