Feature ArticlesCommunication Science as a Compass for the Future

Embracing Information Science and Technology—Decoding,Exploring, and Designing the World▼Abstract

The era in which human beings are confronted with machines (computers or artificial intelligence) as
disparate elements is coming to an end. From here on, we will embrace information science and technology
as part of ourselves. This will necessitate the ability to decode, explore, and design the entire world,including us human beings. While bearing in mind the drastic changes in the information environment thatwe have experienced in the first fifteen years of the twenty-first century, we must think about what shouldmake up the basic research that will form the compass of the future as we envision the year 2030, fifteen
years from now.

New NTT Colleagues
We welcome our newcomers to the NTT Group▼AbstractThe end-faces of optical fibers must be kept clean because unclean
end-faces can cause communication errors. When optical fibers are to
be connected to each other, their end-faces are cleaned and inspectedusing two different devices in two separate time-consuming steps. First,
a fiber cleaner is used to clean each end-face, and then a microscopeis used to inspect each end-face. To simplify this process, wedeveloped a device that integrates the cleaner and the microscope intoa single tool, making it possible to perform both the cleaning and inspection in a single operation without
having to change tools.
