@The technological evolution in the field of ICT has been@achieved mostly with the scope of two dimensions so far. Those are the quantity and quality of information. For an example of the dimension of quantity, their R&D activities were focused on computers capable of processing more information, networks with higher speed and more capacity, data storage functions capable of storing more information, and devices to implement those functions. On the other hand, from the quality viewpoint, relevant R&D activities were focused on the higher fidelity, stereo or stereoscopic presentation, higher presence of analogue information represented by voice and video, the enhancement of accuracy, normality and reliability of digital information, the robustness of information to illegal misuse. These dimensions are not always independent each other, the improvement of quality may cause the enlargement of quantity, or the enlargement of quantity may cause the deterioration of quality. Thus, it proves that the current technologies have been enhanced to evolve the first quadrant on the horizontal axis of quantity and vertical axis of quality. Then, digital technologies have accelerated the enhancement of technological evolution.
However, it has come out that we would face some substantial difficulties which could not be solved with the technological evolution based on only the two dimensional factors. One of the required additional dimensions is time axis. The main issues are how long and accurately the information can remain in any storage function, and simultaneously how long the stored information would be available. The digital technologies can provide quite a lot of advantages so that it has been commenced or discussed in libraries, museums, hospitals, design offices or film centers and so on to digitize and preserve books, documents, design charts, clinical records, photos, movies into archives, while they have faced the sustainability of these digital contents well known as gDigital Dilemmah. Most of current storage functions have the lifetime around 10 years so that they have to complete the migration of information to copy the information before it might be in error. Suppose that the information should be migrated in coming ten years, the overall quantity of information to be copied promptly will increase and fall into a fatal failure. It will be difficult to reserve the budget required for the migration. If the migration cannot be implemented, the digital information will be lost in due course. We can read the ancient history of Egypt existed several thousand years ago through papyrus and read the tale of Genji written one thousand years ago, through Japanese traditional Washi. Then, can the current information be read one thousand years later even if it would not cover the whole information? We have often experienced that conventional storage systems were replaced with newly developed storage systems to be obsolete. Unless we develop technologies to permanently reserve and reactivate the information, the history of human kind will disappear without doubt.
The last one of the required additional new dimensions is the energy to realize the green ICT. It has become distinct and inevitable as the most important issue that we are facing an urgent situation without redundant time to solve the drastic change of global environment and exhaustion of natural resources, in the age of 2010 where every people in every country experience or positively work toward an apparent goal of evenly enjoying the life with high quality which is supported by the modern technologies. It proves an evidence of urgent issue that not only some intelligent people pointed out the importance of the issue in the forum of international politics since Post Kyoto Protocol in 1997, but also the worldwide politics have moved. This issue must be discussed in every field of science and technology. In the field of ICT as well, the dimension of energy required for the evolution of the other three dimensions will not be allowed to increase. Therefore, the technology to enhance the efficiency of energy required for processing, transfer and storage of information per bit will be indispensable.Thus, the evolution of ICT which will extend the overall four dimensional space in harmony is expected, and the research activities focused on the overall aspects of these four dimensions are strongly expected in IEICE as well.
