Koji Korekawa, President, NTT Life Science and Prime
Research Institute for Medical RWD▼Overview
In Japan, the average life expectancy and healthy life expectancy differ by 9 to 12years. Since this gap is not only a social issue but also affects individual well-being,
it is necessary to raise awareness of public health and promote the prevention,
early diagnosis, and treatment of diseases. To address these social issues throughthe use of health and medical big data, the NTT Group has launched two
healthcare companies; NTT Life Science and Prime Research Institute for MedicalRWD. We interviewed Koji Korekawa, president of both companies about theservices provided by these companies and his mindset as a top executive.

Front-line Researchers

Shin’ya Nishida, Senior Distinguished Scientist, NTT
Communication Science Laboratories▼Overview
Many mechanisms by which the human brain recognizes the various complex
properties of objects in the real world remain unknown. Understanding thesemechanisms is critical for scientific understanding of human-sensory-information
processing and advancements in information-engineering technology. Researchersat NTT Communication Science Laboratories are leading research on the humanperception of specific properties of objects called Shitsukan (Japanese word for thesense of quality) from interdisciplinary perspectives, such as information science,neuroscience, and psychophysics, in conjunction with researchers from inside andoutside the laboratories. We asked Shin’ya Nishida, a senior distinguished scientist
at NTT Communication Science Laboratories, about his pioneering research on
Shitsukan and attitude as a researcher.

Toward New-principle Computers

Activities toward New-principle Computers▼Abstract
Non-von Neumann-type computers, such as quantum
computers and Ising machines that operate on principles
different from those of present-day computers, are attracting
attention. They are particularly powerful when applied to specifictypes of problems such as combinatorial optimization problems,
quantum chemical calculations, and prime factorization, andsince solutions to problems such as these can have a significant
impact on society, research of new-principle computers ismoving forward at a vigorous pace. The following Feature
Articles in this issue introduce theoretical and experimental
activities regarding new-principle computers at NTT laboratories
while describing recent advances in this field.
