  Overview
  Japan is a so-called super-aging society, with people aged 65 and older accounting for over 25% of its population. The needs for early detection of diseases and care for elderly people living alone at home are increasing, and it is urgently needed to establish high-precision measurement of biological signals and a platform for processing biological information. In the meantime, society is rapidly globalizing. We asked NTT Fellow Shingo Tsukada of NTT Basic Research Laboratories what kind of stance researchers should take as they tackle research in such an era.

NTT Technology Report for Smart World

• Technology Report for Smart World

  

  Abstract
  NTT Research and Development Planning Department has selected 11 key technologies for realizing a smart world based on social trends for the next 7 to 10 years and published “NTT Technology Report for Smart World.” This article introduces a summary of these 11 technologies and the social changes that will be brought about by such technologies.

• Electron Spin Resonance Spectroscopy Using a Superconducting Flux Qubit

  

  Abstract
  We use a superconducting flux qubit for the sensing application of electron spin resonance (ESR) spectroscopy. The superconducting flux qubit is a highly sensitive magnetometer with micrometer-scale spatial resolution. The sensitivity of our spectrometer is 400 spins/√Hz, and the sensing volume is 0.05 pL. This high sensitivity and high spatial resolution enable us to investigate a small number of electron spins in a microscale area. The spectrometer also obtains a wider ESR spectrum range with two-parameter (frequency and magnetic field) scanning. This enables us to refine the material parameters.

Global Standardization Activities

• Activities of ITU-T Study Group 5 (Environment, Climate Change and Circular Economy) and Discussion Results

  

  Abstract
  The NTT Group participates in the development of international standards by the International Telecommunication Union - Telecommunication Standardization Sector (ITU-T) with a view to protecting telecommunication equipment from electromagnetic interference and lightning surges, assessing the impact of information and communication technology on climate change, promoting a circular economy conducive to sustainable development, enhancing the reliability of telecommunication services, and reducing the environmental load of the Group’s business activities. This article reports on the main discussion results of the ITU-T Study Group 5 meeting held in September 2018.

Practical Field Information about Telecommunication Technologies

• Countermeasures against Insect Damage to User Equipment—Repellent Sheet and Repellent Spiral

  

  Abstract
  Telecommunication equipment can malfunction if it is damaged by insects. It is therefore necessary to develop measures to prevent such damage. This article presents examples of the damage that can occur when cockroaches nest inside equipment and introduces two products designed to stop them from accessing the equipment. This is the fifty-third article in a series on telecommunication technologies.
