  • Community-based precision farming is a new concept of agricultural systems, which leads to organize groups of wise farmers and technology platforms in Japan. The wisdom farmers create a rational farming system to manage hierarchical variability: variability in farmers' community as well as variability of within-field and between-field. The technology platform develops and provides three key-technologies: mapping technology, variable-rate technology, and decision support systems available for rural constraints. Advancement of bio-production robots leads precision farming to the next level, where two technological innovations: how to produce and manage information-oriented fields and information-added products, can be attained.

  • In Vehicle Information and Communication System (VICS), which is an active field of Intelligent Transport System (ITS), information of traffic congestion is sent to each vehicle at real time. However, a centralized navigation system is not realistic to guide millions of vehicles in a megalopolis. Autonomous distributed systems should be more flexible and scalable, and also have a chance to focus on each vehicle´s demand. This paper proposes a sub-optimal route planning mechanism of vehicles in urban areas using the non-network type immune system. Simulation is carried out using a cellular automaton model. This system announces a sub-optimal route to drivers in real time using VICS.

  • In this paper, we implemented technology assessment on the public R&D activities in IT field in order to select the promising technologies, so called "star technology," making for national industry development. Technology assessment frame in this study included qualitative factors. IT technologies are classified five sector - network, wireless/broadcasting, SW/application/computer/terminal equipment, semiconductor/component. Expert opinion interviews on each field are carried out. Assessment factors consist of technology usefulness and technology competitiveness. In the final analysis, 23 technology items selected as a promising technologies and the results can be used public R&D planning and If industry policy.

  • Recently technological advancements have allowed visible, infrared and thermal imaging systems to be readily available for security and access control. Increasing applications of facial recognition for security and access control leads to emerging spoofing methodologies. To overcome these challenges of occlusion, replay attack and disguise, researches have proposed using multiple imaging modalities. Using infrared and thermal modalities alongside visible imaging helps to overcome the shortcomings of visible imaging. In this paper we review and propose hybrid feature extraction methods to combine data from multiple imaging systems simultaneously.

  • End-User Computing (EUC) is one of the most significant developments in corporate computing in the 1980's. An information center (IC) supports EUC by providing end-users with technical assistance and consulting services. This study investigates the effective management and implementation of an IC in an organization with respect to the three sociotechnical factors : characteristics of end-users, social relationships with the DP/MIS department, and 3) technological infrastructure of EUC. An exploratory framework for managing IC is developed based on extensive literature review and results from interviews with IC directors of 17 large companies in the midwestern region in U.S.A.

  • Nowadays the role of region has been increased, as knowledge, science and technology become important in economic development. This paper argues that a system approach is needed to enhance regional S&T capabilities. Under the this approach, we can identify a concept of regional innovation systems as sub-systems of a national innovation system. This paper investigates Korean regional innovation systems based on R&D budget of regional governments. According to this paper, Korean regional governments' R&D investment is very insufficient. There were no co-relationship between regional governments' fiscal autonomy from the central government and their R&D investment. This paper argues that such a poor investment will restrict the future development of Korean regional innovation systems. Therefore, this paper suggests some strategic options for the development of regional innovation systems as follows. First, regional governments should increase their R&D budget. Second, their R&D efforts should be related with their specific industrial sectors. Third, they should target not only to create new promising industrial sectors but also to enhance technological capabilities of existing sectors. Fourth, their target group should be small and medium-sized enterprises. Finally, regional governments should adopt small and incremental approach to improve their innovation systems.
