“Life-World”: Beyond Fukushima and Minamata
( Shoko Yoneyama ) 경남대학교 극동문제연구소 2013 ASIAN PERSPECTIVE Vol.37 No.4
The human and ecological disasters of Minamata and Fukushima highlight Japan`s need to plan for a sustainable future. Ogata Masato, a Minamata fisherman, through his philosophy of “lifeworld” suggests that this quest for a sustainable future requires a change in the epistemology of social science. His philosophy offers a postmodern version of Japan`s heritage of animism, where humans are connected with all living beings, including the souls of the living and the dead, as well as animate and inanimate entities in nature. His philosophy thus presents an alternative framework for a new modernity. KEYWORDS: Fukushima, Minamata, World Risk Society, nuclear disaster, environmental ethics, connectedness, lifeworld, Ulrich Beck, Ogata Masato.The human and ecological disasters of Minamata and Fukushima highlight Japan`s need to plan for a sustainable future.

Development of millimeter wave radar front-end for car collision avoidance using NRD guide
Tsukasa Yoneyama,신천우 에스케이텔레콤 (주) 1999 Telecommunications Review Vol.9 No.4
We've succeeded in developing a millimeter wave FM-CW radar that has a power of 10 mW at a frequency of 60 GHz. With the use of the radar, a vehicle which is 150m away from it, can be detected and even a small sized obstacle can also be detected. Since the radar adopts an NRD guide to propagate a millimeter wave, it can be produced at a low production cost. we can also, fabricate a millimeter wave radar of high quality in a convenient way because it is small in size and has a simple circuit. With those great capabilities, the radar is expected to fully function as a car collision avoidance radar. In addition, owing to its high quality of reproduction, it can be produced in large numbers and before long, it would be put into practical use.
Proposal of a flexible translational joint mechanism for humanoid robots
Takehiro Yoneyama,Kazuyuki Ito 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10
Recently, applications of robots for home assistant, helper and rehabilitation have attracted considerable attention, and various humanoid robots are developed. In such environments, robots have to handle unexpected disturbance very quickly. Especially, external forces owing to collision to obstacles or people are one of significant problems, because they causes risks to injure human bodies or to break own structures. However, almost conventional robots consist of rigid structures, so, many sensors and high-spec controller is required for handling external forces. To address this problem, flexible structures like a muscle have attracted considerable attentions. By employing flexible structures, we can reduce sensors and controllers, because the flexible structures can adapt themselves to the unknown environment by utilizing their physical properties without sensors or controllers. In this paper, we focus on flexible mechanism, and propose a flexible translational joint of which flexibility can be adjusted adaptively. We employ the proposed flexible joints for legs of a humanoid robot, and we conduct experiments of walking on vibrated plane. As the result, we confirm that the developed humanoid robot can walk on the vibrated plane, due to the filtering properties of the flexible joints.
